3 * Fixed a bug in the pid writing function, which couldn't be
4 written in a root-owned directory.
6 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Defined that channel message to unknown Channel ID must
9 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
10 Updated the protocol specs and the code in server. The
11 affected file is silcd/packet_receive.c.
13 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
16 that it is used to send error notifys if error occurs during
17 some SILC packet processing, except commands. The error
18 types are same as for command reply types. Defined that
19 if private message is sent to unknown Client ID the error
20 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
21 Updated the protocol specs and code. Affected files are
22 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
23 lib/silcclient/client_notify.c, silcd/packet_receive.c,
24 and irssi/src/silc/core/client_ops.c. Renamed the
25 SilcCommandStatus to SilcStatus.
27 * Defined the use of extra WHOIS attributes in WHOIS command.
28 The <Requested Attributes> (defined in a separate document)
29 can be used to request additional information about user
30 not returned by standard WHOIS command. Defined that server
31 can send WHOIS command directly to client. Client provides
32 the requested attributes to the server. Updated the protocol
33 specs. Protocol TODO #4. Implementation is not done yet
36 * Renamed function silc_client_command_status_message to
37 silc_client_status_message. Affected files are
38 lib/silcclient/command_reply.[ch].

56 options to the server. Affected files silcd/serverconfig.[ch],
57 silcd/command.c and silcd/packet_receive.c.
59 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
61 * Added resolve_cmd_ident field to the SilcClientEntry structure
62 too so that if the entry is for example being resolved so
63 another command may attach to the same pending command reply
64 without requiring to resolve the same entry again. Added
65 support for adding multiple pending commands for one
66 command idenfier. Affected files lib/silcclient/command.[ch],
67 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
69 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
71 * Defined that server receives WHOIS command reply for private
72 and secret channels too. Updated protocol specs and the
73 code in server. Affected file silcd/command.c.
75 * Defined <channel user mode list> argument to WHOIS command
76 reply for returning user modes on the channels. The
77 channel list now doesn't include the user mode anymore but the
78 actual channel mode. Updated protocol specs and the code in
79 client and server. Affected files are silcd/command_reply.c,
80 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
81 and lib/silcclient/command_reply.c.
83 * Save the channels list in WHOIS command reply in normal server
84 so that WHOIS always shows joined channels also in normal
85 server and not just on router. Affected file is
86 silcd/command_reply.c.
88 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

94 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Changed the UMODE's mode mask argument to be optional. If
97 not provided then the command merely returns the current mode
98 mask to the client. Updated protocol specs and the server.
99 Affected file is silcd/command.c.
101 * Added SILC session detachment/resuming support. It is possible
102 to detach by closing the network connection and then re-connect
103 and resume to the old client session. Added DETACHED user
104 mode that server will set for detached client. Added new
105 packet RESUME_CLIENT which is used to perform the resuming
106 process. Added DETACH command. Updated the protocol specs,
107 core library, client and server. Protocol TODO #22. Very
108 many affected files around the tree.
110 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Changed the CMODE's mode mask argument to be optional. If
113 not provided then the command merely returns the current mode
114 mask to the client. Updated protocol specs and the server.
115 Affected file is silcd/command.c.
117 * Changed the Killer's Client ID in KILLED notify to be just
118 any ID payload since router server is allowed to kill as well.
119 Updated protocol specs, client libary and server. Affected
120 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
121 and irssi/src/silc/core/client_ops.c.
123 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Added new user modes ANONYMOUS for special anonymous servers
126 that may set the mode for client, and BLOCK_PRIVMSG which
127 client may set to block incoming private messages unless the
128 Private Message Key flag is set (using private keys to protect
129 private messages). Updated protocol specs and code in client
130 and server and core library. Protocol TODO #23. Affected
131 files are lib/silccore/silcmode.h, silcd/server.[ch],
132 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,

136 may set to itself to tell server not send channel messages.
137 Other packets such as channel key packets are still sent.
138 Protocol TODO #23. Updated the protocol specs, client and
139 server. Affected files are lib/silccore/silcmode.h,
140 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
141 lib/silcutil/silcutil.c, silcd/command.c, and
144 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Redefined the Status Payload to include now two 8 bit fields,
147 instead of one 16 bit field. This now makes it possible to
148 send list of errors. Updated the protocol specs and the code
149 in core library, client library and server. Protocol TODO #1.
150 Affected files are lib/silccore/silccommand.[ch],
151 lib/silcclient/command_reply.[ch], silcd/command.c,
152 silcd/command_reply.c and silcd/packet_receive.[ch].
154 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
156 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
157 must be handled by the application and should tell the application
158 that an error message was already printed, and it should print the
159 config coords (line, filename, ...). Affected files are
160 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
162 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
163 server config parsing code more readable.
165 Fixed a bug in the fetch_logging() config callback.
167 Affected files is silcd/serverconfig.c.
169 * Drop root privileges when started in foreground. Don't drop them

178 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
179 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
181 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
183 * Added STATS command to the protocol after all, to return
184 various statistical information about the network. It can
185 be used by clients to retrieve statistical information, and
186 servers may use it to to fetch cell and network wide
187 statistics from router. Updated the protocol specs and
188 implemented it to the server. Protocol TODO #16.
189 Affected files are lib/silccore/silccommand, silcd/command.[ch],
190 silcd/command_reply.[ch].
192 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
194 * The LIST command reply in client libary now adds new channel
195 entry if the returned channel doesn't exist yet in cache,
196 and returns the channel entry to the application in the
197 command_reply client operation. Affected file is
198 lib/silcclient/command_reply.c.
200 * Changed the channel message payload's MAC generation to
201 include the IV in the MAC as well. This way all relevant
202 parts of the channel message payload are authenticated also
203 with the channel message MAC (and not only by packet MAC).
204 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
205 Affected file is lib/silccore/silcchannel.c.
207 * Fixed the SKE to save the remote version, since the
208 silc_ske_parse_version mistakenly checked wrong version,
209 after it replaced the start payload. Affected files are
210 lib/silcske/silcske.[ch].
212 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
214 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

216 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
217 Affected files lib/silcutil/silcstrutil.[ch].
219 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
220 files are lib/silcutil/silcstrutil.[ch].
222 * Defined that the security property fields in SKE SHOULD be
223 UTF-8 encoded, defined that version string MUST be US-ASCII
224 encoded, defined that passphrases sent in connection
225 authentication protocol MUST be UTF-8 encoded. Implemented
226 these to the client and server. Defined also that other
227 passphrases sent in the protocol MUST be UTF-8 encoded.
228 Affected files are lib/silcske/silcske.c,
229 lib/silcclient/protocol.c, silcd/protocol.c,
230 silcd/serverconfig.c, and lib/silccore/silcauth.c.
232 * Changed the silc_client_close_connection interface to not
233 need the SilcSocketConnection which should not be visible
234 to application. Affected files are lib/silcclient/client.c
235 and lib/silcclient/silcclient.h.
237 * Rewrote the text for Private Message Key Payload in the
238 protocol specification. Protocol TODO #11.
240 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
242 * Upgraded the protocol version to 1.1, updated protocol specs
245 * Added the nickname as new argument to NICK_CHANGE notify and
246 added it to protocol specs and implemented it to client and
247 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
248 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
249 lib/silcclient/client_notify.c.

255 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
256 The killer's client entry is now returned to application in
257 the `notify' client operation.
259 * Fixed the Max Argument fields that had too large value set
260 in the protocol specs. Protocol TODO #14.
262 * Added the LEAVE command reply to return the ID of parted
263 channel. Updated protocol specs and implemented it to the
264 client and server. Protocol TODO #15. Affected files are
265 silcd/command.c, lib/silcclient/command_reply.c. The channel
266 entry is now returned to application in the `command_reply'
269 * Rewrote the version SKE version checking in client libary
270 and in server to use the silc_parse_version_string. Affected
271 files are lib/silcclient/protocol.c, silcd/protocol.c.
273 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
274 commands that was missing it, and updated protocol specs and
275 the server implementation. Protocol TODO #10. The affected
276 file is silcd/command.c.
278 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
279 generic reply to a generic request (REQUEST flag), and
280 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
281 way. A draft-riikonen-silc-flags-payloads-00.txt is written
282 to define the payload for DATA flag. Added the flags to
283 the implementation. Protocol TODO #9. Affected file is
284 lib/silccore/silcchannel.h.
286 Changed the client library to return the message length
287 to application as well in the channel_message and private_message
288 client operations. Affected files are
289 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
290 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
291 and lib/silcclient/client_ops_example.c.
293 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
294 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
295 the channel. Updated protocol specs and impelemented this
296 to client and server. Protocol TODO #6. Affected files are
297 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
298 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
300 Added new options m and M to CMODE command in Irssi SILC
301 client to set these modes.
303 * Deprecated all administrative commands from SILC protocol
304 since they are highly implementation specific commands.
305 Updated protocol specs. Moved the old commands in
306 implementations to private range of command types. Affected
307 files are silcd/command.c, lib/silcclient/command.c and
308 lib/silcclient/command_reply.c. Protocol TODO #8.
310 * Fixed a bug in server where sending unknown command crashes
311 the server. Affected file silcd/command.c.
313 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
315 * Added SILC_PROTOCOLVERSION macro to check protocol version
316 of a socket connection. The affected file is
317 lib/silcutil/silcsockconn.h.
319 * Added better error logging in rekey protocol. Affected file
322 * Do not check public key types in SKE during rekey. Affected
323 file lib/silcske/payload.c.
325 * Fixed the rekey protocol with PFS, which was totally broken.
326 Affected file silcd/protocol.c.
328 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Some client implementations quit network by doing first LEAVE
331 and then immediately SIGNOFF (like Bombyx). We now do check
332 after a short time after LEAVE notify and check whether the
333 client is still valid after LEAVE, and if not we remove it from
334 cache. Affected file is lib/silcclient/client_notify.c.
336 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
338 * Merged version 1.1.4 of zlib. Even if it not currently in use,
339 it's good not to have security holes here.
341 * Fixed a negative refcount situtuation for the config context.
342 Affected file is silcd/serverconfig.c.
344 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
346 * ROBOdoc documented lib/silcutil/silcutil.h.
348 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Optimized even more the SilcPacketContext structure. Now
351 totally saved 16 bytes of memory per context after optimization.
352 Affected files are lib/silccore/silcpacket.[ch].
354 * Made strict checks for valid SILC IDs. Affected file is
355 lib/silccore/silcid.c.
357 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Changed the object argument for silc_cipher_register,
360 silc_hash_register, silc_hmac_register and silc_pkcs_register
361 to const. Affected files are lib/silccrypt/silccipher.[ch],
362 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
364 * Changed the silc_get_username and silc_get_real_name to
365 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
367 * Fixed the Irssi SILC Client to use the silc_get_username and
368 silc_get_real_name insted of glib routines since the glib
369 routines only corrupt stack. Fixes the Irssi SILC to work in
370 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
372 * Fixed the Irssi to not use g_get_home_dir since it crashes
373 or returns garbage on cygwin and corrupts stack. Added function
374 get_home_dir to Irssi routines. Affected files are
375 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
377 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
379 * Made some structure optimizations. SFTP memory FS MemFSEntry
380 entry structure. Optimized SilcTask structure. Optimized
381 SilcPacketContext structure.
383 Affected files lib/silcsftp/sftp_fs_memory.c,
384 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
386 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
388 * And yet again reverted back the config thing since Johnny
389 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
392 * Fixed memory leaks from config object. Affected files are
393 silcd/serverconfig.[ch].
395 * Added support for adding new connections to the server in rehash.
396 After rehash they take effect.
398 Added support for changing the maximum allowed connections in
399 rehash. The number can grow but going smaller is not supported.
401 Added function silc_server_num_sockets_by_remote to the
402 silcd/server_util.[ch].
404 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
406 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
408 * Added preliminary checking during config parsing for a valid
409 public/private key and removed further checks in the code.
410 Affected files are silcd/serverconfig.[ch], server.c.
412 * Moved functions silc_server_drop() and silc_server_daemonise()
413 from server.c to silcd.c since they are stricly related to
414 the application activity.
416 * Reverted a small part of the automatic ref/unref since
417 it caused a double unref in some situations. Affected
418 files are silcd/silcd.[ch], server.c, serverconfig.c.
420 * Added some .cvsignore files in the lib directory.
422 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
424 * Fixed silc_net_gethostbyaddr to correctly resolve by
425 address. Affected file lib/silcutil/silcnet.c.
427 * Fixed the notify relaying to client. The HMAC to be used
428 with relayed packets ws wrong and caused decryption failure
429 at the client end. Affected file is silcd/packet_receive.c.
431 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
433 * Created new branch silc_protocol_1_0_branch.
435 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
437 * Changed the silc_server_config_* routines to be SilcServer
438 independent. They are now officially application specific code
439 and not part of generic server implementation. Affected files
440 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
442 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
444 * Added automatic referencing of config context in the
445 silc_server_config_alloc, and automatic unreferencing in the
446 silc_server_config_destroy. Affected files are
447 silcd/serverconfig.[ch], silcd/silcd.c.
449 * Fixed the silc_log_quick handling in the logging routines.
450 It didn't log quickly when it was TRUE. Affected file is
451 lib/silcutil/silclog.c. Also the flush delay was set even
452 if it was 0 in config file. Affected file is
453 silcd/serverconfig.c.
455 * Added support for changing key pair of the server in rehash.
456 Affected file silcd/server.c.
458 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
460 * Fixed the TOPIC_SET notify to not cras. It changed the topic
461 too early, before getting the channel entry. Affected file
462 is silcd/packet_receive.c.
464 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
466 * Added functions silc_server_config_[ref/unref], these are used
467 to prevent that the config object is destroyed.
469 No longer directly affect global variables silc_log_quick and
470 silc_log_delay, they are first cached inside the config object
471 and then applied with silc_server_config_setlogfiles().
473 silc_server_config_set_defaults() is now internal to
474 serverconfig.c, there are no reasons to show this internal stuff
477 Affected files are silcd/serverconfig.[ch].
479 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
480 fprintf's to stderr, since some code may be executed again after
481 the server went into the background. Affected files are
484 * Added rehash support. Added function silc_server_rehash() that
485 will perform all the basic tasks of the rehashing procedure.
487 * Added command line option `-x, --hexdump'. This will enable the
488 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
489 The option `--hexdump' implies `--debug'.
491 * Fixed a bad bug in the logging APIs (silcutil library) where
492 the application would crash after calling silc_log_reset_all().
494 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
496 * Fixed the KICKED notify handling in client library to
497 correctly remove the channel and all entries from the
498 channel when I was kicked. This bug crashed the client.
500 Fixed yet another but in KICKED notify handling to remove
501 the kicked client correctly from the channel.
503 Affected file is lib/silcclient/client_notify.c.
505 * Fixed a minor bug in looking up correct client entry
506 in KICKED notify in server. Affected file is
507 silcd/packet_receive.c.
509 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
510 sources correctly to distribution. Fixes --with-gmp option.
512 * Removed the manual rehashing from ID Cache, and changed it
513 to use the SILC Hash Table's auto rehash feature. Affected
514 file is lib/silccore/silcidcache.c.
516 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
518 * Fixed a bug in the silc_client_nickname_format function that
519 handles the multiple same nickname formatting. Two clients
520 with same nickname caused problems after the first one left
521 and rejoined. It didn't format the nickname correctly.
522 Affected file is lib/silcclient/idlist.c.
524 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Don't change the topic if olod topic is same as new one.
527 Affected file is silcd/packet_receive.c.
529 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
531 * Added cross-reference support to the SILC Documentation
532 generator. All types across all HTML files are now cross-
533 referenced. Affected files util/robodoc/generator.c and
534 scripts/silcdoc/silcdoc.
536 * Added file lib/silcutil/silctypes.h to include all the
537 arithmetic type definitions and some macros. Removed
538 includes/bitmove.h and moved macros to silctypes.h.
540 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
542 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
544 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
546 * Added `type' argument to silc_id_payload_parse_id function which
547 now returns the type of the ID to the sent pointer. Affected
548 file is lib/silccore/silcid.[ch].
550 * Added check for CMODE_CHANGE notify type that mode change is
551 allowed by the sender. Affected file silcd/packet_receive.c.
553 * Added check for CUMODE_CHANGE notify type that mode change is
554 allowed by the sender. Affected file silcd/packet_receive.c.
555 Added the ID type as CUMODE_CHANGE notify type as argument
556 to the `notify' client operation. Affected files are
557 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
559 * Added function silc_client_add_server to the client library.
560 Added support for resolving also channel and server info when
561 received unknown entity in notify packet. Affected files are
562 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
564 * Added function silc_command_get_status to return the command
565 status from the command reply's argument payload. Affected files
566 are lib/silccore/silccommand.[ch].
568 * Added check for KICKED notify type that the kicking is
569 allowed by the client. Affected file silcd/packet_receive.c.
571 * Created function silc_get_input which can be used to get input
572 (echo on or off) from user on command line. Affected files are
573 lib/silcutil/silcutil.[ch].
575 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
577 * Optimized silc_server_packet_relay_to_channel function.
578 Added new function silc_channel_message_payload_encrypt which
579 can be called directly if channel message payload needs to
580 be encrypted and is already encoded (no need to call _encode
581 function). Packet relaying is now done by router without any
582 extra memory allocations. Affected files are
583 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
586 * Fixed the INVITE notify handling. It took wrong arguments
587 as invite list and invite delete. Affected file is
588 silcd/packet_receive.c.
590 * Added check for TOPIC_SET notify type that the topic change is
591 allowed by the client. Affected file silcd/packet_receive.c.
593 * Added check for INVITE notify type that inviting is allowed by
594 the client. Affected file silcd/packet_receive.c.
596 * Changed the silc_server_client_on_channel to return the
597 SilcChannelClientEntry as well. Moved the function
598 silc_server_check_cmode_rights to server_util.[ch].
599 Affected files are silcd/server_util.[ch], silcd/command.c.
601 * Added function silc_server_check_umode_rights to check whether
602 changing client's user mode is allowed. Added check for
603 UMODE_CHANGE notify type that the umode change is allowed
604 by the client. Affected files are silcd/server_util.[ch],
605 silcd/packet_receive.c and silcd/command.c.
607 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
609 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
610 ID length. It ignored that ID can be IPv6 based as well.
611 Affected file lib/silccore/silcpacket.h.
613 * Fixed the silc_id_id2str and silc_id_str2id to take the
614 IPv6 address offset's into consideration. Affecte file is
615 lib/silccore/silcid.c.
617 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * Fixed the internal Unix scheduler functions to check for
620 NULL context they may receive. The affected file is
621 lib/silcutil/unix/silcunixschedule.c.
623 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
625 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
626 can specify different directory with --home command line
627 parameter. Affected files irssi/src/silc/core/client_ops.c,
630 * SILC-specific commands aren't now executed if the active server
631 isn't of SILC-type, so there won't be problems with having
632 IRC and SILC protocol support in same client. Affected files
633 irssi/src/silc/core/silc-channels.c, silc-servers.c,
636 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
638 * Improved the signal support in SILC Schedule. Added new
639 function silc_schedule_signal_call which is used by application
640 to mark a signal to be called. It is now safe to perform
641 any kind of tasks in signal callbacks since it is guaranteed
642 that the application specified signal callback is called
643 after the signal is over. Affected files are
644 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
646 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
648 * Added `name' field to SilcChannelPrivateKey to represent
649 application given name for the key. Moved also the context from
650 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
651 Added the `name' argument also to the function
652 silc_client_add_channel_private_key.
654 Added function silc_client_current_channel_private_key to set the
655 current channel private key in use.
657 Added "change" command to KEY command which can be used to change
658 the current channel private key. Bound the command also to
661 Also affected files lib/silcclient/client_channel.c,
662 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
664 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Added silc_rng_get_byte_fast function in to the
667 lib/silccrypt/silcrng.[ch].
669 * Changed the interface of silc_packet_assemble and the
670 silc_packet_send_prepare. If silc_packet_assmble is now
671 called the application does not call silc_packet_send_prepare
672 because the library will call it automatically. These
673 interfaces now also return a reference to the outgoing buffer
674 which includes the assembled packet, which the application can
675 use to encrypt the packet.
677 Affected files are lib/silccore/silcpacket.[ch],
678 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
679 silcd/packet_send.c, server_backup.c and packet_receive.c.
681 * Fixed a packet sending bug on very high load, where outgoing
682 packet queue wasn't handled correctly and packets got corrupted.
683 Affected files are lib/silcutil/*/silc*sockconn.c,
684 lib/silcclient/client.c and silcd/server.c.
686 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
688 * Added macro SILC_PACKET_DATALEN which can be used during
689 packet assembling to check whether the data to be added to
690 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
691 len is truncated until it fits it.
693 Added checks for maximum length of channel message payload and
694 private message payload also.
696 Added checks for maximum packet length in server and in
699 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
700 lib/silcclient/client.c, lib/silccore/silcchannel.c and
701 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
702 lib/silcclient/client_prvmsg.c.
704 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Added silc_server_packet_queue_purge call to the
707 silc_server_disconnect_remote to assure that all data in the
708 queue before disconnecting is sent to the network. Affected
711 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Added the deleting of server's own ID cache entry to the
714 silc_server_free function. Free also everything else that
715 has been allocated in silc_server_init. The affected file
718 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
720 * Added functions silc_parse_version_string, silc_version_to_num,
721 and silc_ske_parse_version to parse SILC protocol style version
722 strings. Affected files lib/silcutil/silcutil.[ch] and
723 lib/silcske/silcske.[ch].
725 * Added new configuration params: version_protocol, version_software
726 and version_software_vendor to specify what version the remote
727 host must at least be to be able to connect to server. The vendor
728 string can be regex matched too. Added new function
729 silc_server_connection_allowed to check maximum number of allowed
730 connections, and allowed versions for incoming connections.
731 Affected files are silcd/server.c, server_util.[ch] and
734 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
736 * Added preliminary support for signals in scheduler. The
737 signals we care about are now blocked always when the scheduler
738 is locked. This way we can synchronise the use of signal with
739 scheduler. It is guaranteed that when signal occurs the scheduler
740 is not locked, and thus new tasks can be safely added to the
743 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
744 to silc_schedule_internal_init and silc_schedule_internal_uninit.
745 Added new platform specific routines
746 silc_schedule_internal_signals_[un]block and
747 silc_schedule_internal_signal_[un]register.
749 Added new functions to SILC Schedule API:
750 silc_schedule_signal_[un]register. Each signal that application
751 is going to use should be registered to the scheduler.
753 Affected files are lib/silcutil/silcschedule.[ch],
754 lib/silcutil/*/silc*schedule.c.
756 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
758 * Check for unauthenticated client and server in the
759 silc_server_new_client and silc_server_new_server functions.
760 Affected file silcd/packet_receive.c.
762 * Added function silc_string_is_ascii to check whether given
763 string is 7-bit ASCII string. Affected files are
764 lib/silcutil/silcutil.[ch].
766 * Added function silc_id_is_valid_server_id into the
767 silcd/serverid.c and added checking for valid Server ID's in
768 silc_server_new_server. The Server ID must always be based
769 on the server's public IP address.
771 * Added logging of DISCONNECT packet message in the server.
772 Affected file silcd/server.c.
774 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
776 * Changed all library interfaces that use Global RNG to also
777 accept SilcRng as argument. Affected files are
778 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
779 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
780 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
781 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
784 * Added function silc_pkcs_generate_key to the
785 lib/silccrypt/silcpkcs.[ch] for applications so that they
786 don't need to do pkcs->pkcs->init calls anymore.
788 * Remove SilcSocketConnection from the SFTP API since it really
789 wasn't needed there. The application has the information
790 saved in its contexts anyway and the SFTP layer doesn't need
791 know about it. Affected files lib/silcsft/silcsftp.h and
792 lib/silcsftp/sftp_[server/client].c.
794 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
795 The SilcSimContext is not SilcSim.
797 * Fixed possible buffer overflows in silc_id_render in the
798 lib/silcutil/silcutil.c.
800 * On EPOC the global crypto module lists are not used at all
801 in the crypto library. Added support for using the constant
802 algorithm list on EPOC. Affected files are
803 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
806 * Fixed the handling of third parameter of KICKED notify, since
807 it was mistakenly updated to SILC Protocol 1.0 even though it
808 is to be included in 1.1. Since it is not in 1.0 it is not
809 mandatory, and this fix now handles it only if it is provided,
810 and it is not error if it is not provided. Affected file
811 lib/silcclient/client_notify.c.
813 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
815 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
816 client. Affected file irssi/src/silc/core/client_ops.c.
818 * Merged with Irssi 0.8.4 from irssi.org CVS.
820 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Check for valid socket connection in client entries before
823 sending any messages. Fixes a crash, but doesn't fix some
824 other underlaying bug that is lurking there. Affected
825 file silcd/packet_send.c.
827 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
829 * $usermode, $cumode and $cumode_space expandos shouldn't do
830 anything with non-SILC server records. Affected file
831 irssi/src/silc/core/silc-expandos.c
833 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Fixed the silc_net_check_[host/local]_by_sock to support
836 IPv6 bound sockets as well. Now they can return IPv6 addresses
837 as well. Affected file lib/silcutil/silcnet.c.
839 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
840 Affected lib/silcutil/unix/silcunixnet.c.
842 * Fixed ID rendering (at least on some platforms, not NetBSD)
843 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
845 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
847 * Added silc_hash_public_key and silc_hash_public_key_compare
848 functions to be used with SilcHashTable. They can be used to
849 hash public keys and compare public keys in hash table. Affected
850 file lib/silcutil/silcutil.[ch].
852 * Added support for specifying multiple public keys for Client
853 connection section in server configuration file. This makes it
854 possible to accept multiple public keys from same host, or to
855 make a section that accepts any incoming host, and have the
856 accepted public keys listed in the section.
858 Added functions silc_sever_[find/get]_public_key, added the
859 support for this actually to all connection sections but only
860 the Client section is currently allowed to specify multiple
863 Affected files are silcd/server.c, server_internal.h,
864 command.c, protocol.c, server_util.[ch], packet_receive.c.
866 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
868 * Merged Irssi 0.8.2 from irssi.org CVS.
870 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
872 * If silc_debug is TRUE, also output standard logging messages
873 to stderr with the debug output.
875 Made silc_log_reset_all() flushing all channels before returning.
876 Also fixed some documentation typos.
878 Affected files are lib/silcutil/silclog.[ch].
880 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
882 * Fixed the server to check correctly the amount of connections
883 from single host, by checking also the type of the connection.
884 Fixed also the comparison of number of connections and number
885 of allowed connections. Affected files are silcd/server.c,
888 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
890 * Fixed the USERS command reply to save the user's mode on the
891 channel as well. Fixed JOIN command reply to check whether a
892 client is on channel already and not join it twice. Affected
893 file lib/silcclient/command_reply.c.
895 * Added new file silc-expandos.c into irssi/silc/core/ to return
896 various stuff for various signal for the statusbar etc. updating.
897 Now Irssi SILC client prints channel user modes etc. on the
900 * The user mode (like server/router operator changes) is now shown
901 on the Irssi SILC client's statusbar. The affected files are
902 irssi/src/silc/core/client_ops.c, silc-expandos.c.
904 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
906 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
907 to SILC_SCHEDULE_[UN]LOCK macros.
909 * Added more error printing to logs in server code. Affected
910 files silcd/server.c and silcd/protocol.c.
912 * Fixed -S option parsing in Irssi SILC Client. Affected file
913 irssi/src/silc/core/silc-core.c.
915 * Added silc_buffer_alloc_size function. Affected file is
916 lib/silcutil/silcbuffer.h.
918 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
921 constants. Affected files in
922 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
925 * Changed the internal SFTP Memory FS table to const. Affected
926 file lib/silcsftp/sftp_fs_memory.c.
928 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed the buffer formatting and unformatting routines to
931 check the size of 64 bits types with sizeof(). Affected
932 file is lib/silcutil/silcbuffmt.c.
934 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
936 * Removed 0.6.x backwards support.
938 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
940 * Changed all integer type names:
941 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
942 to avoid collisions with other libraries using same type names
945 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
947 * Added `prefer_ipv6' argument to the functions
948 silc_net_gethostbyname[_async]. If it is TRUE it will return
949 IPv6 address over IPv4. If FALSE IPv4 address is returned
950 even if IPv6 address was found. Affected files
951 lib/silcutil/silcnet.[ch].
953 * Added support silc_net_create_connection[_async] to fallback
954 to IPv4 address if IPv6 address could not be used (like if
955 it doesn't work on a specific system). Affected file in
956 lib/silcutil/unix/silcunixnet.c.
958 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
960 * Added silc_schedule_reinit function to do the enlarging
961 of the max tasks handling capabilities of the scheduler.
962 Affected files lib/silcutil/silcschedule.[ch].
964 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
966 * Added automatic extern "C" { ... } for C++ compilers so the
967 application does not need to define them. Affected file
968 includes/silcincludes.h.
970 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
971 old name went against naming convention. Applications now
972 include "silcclient.h" instead of "clientlibincludes.h".
973 Removed includes/clientlibincludes.h, it is redundant now.
975 * Renamed includes/version.h to silcversion.h.
977 * Added really preliminary support for OS/2 into the util
978 library. Only thread & mutex API is implemented, others
979 are still to be implemented. Created the lib/silcutil/os2/
980 directory. Created also file includes/silcos2.h.
982 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
984 * Added preliminary BeOS support into the util library.
985 Created lib/silcutil/beos/, and implemented all the needed
986 functions to support SILC on BeOS. Created also file
989 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
991 * Added proper initializations to silc's irssi code, so it's
992 now possible to load it as module. Affected files
993 irssi/src/silc/core/silc-core.c,
994 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
996 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
998 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1001 * Fixed the silcdoc document generator to correct generate
1002 docs from all kinds of filenames. Affected files are
1003 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1005 * ROBOdoc documented lib/silcutil/silcmemory.h.
1006 Added also new function silc_memdup.
1008 * Removed lib/silcutil/silcbufutil.h and moved those routines
1009 to the lib/silcutil/silcbuffer.h.
1011 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1013 * Added `user_count' to the SilcChannelEntry which now tells the
1014 number of users on the channel. The user count is now saved
1015 in normal server of global channels as well. Affected files
1016 silcd/server.c, idlist.h, packet_receive.c and command.c.
1018 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1019 include file utility functions.
1021 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1022 instead of calling directly OS routines.
1024 * Fixed NICK change printing in Irssi SILC Client. Fixed
1025 KICKED notify printing in Irssi SILC Client. Affected file
1026 irssi/src/silc/core/client_ops.c.
1028 * Fixed a NICK change bug in client library, to not recreate the
1029 client_entry->channels hash table everytime nick is changed.
1030 Affected file lib/silcclient/client.c.
1032 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1034 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1035 the SKE interface a bit.
1037 * Fixed padding problem in PKCS#1. The padding was not actually
1038 random since the random number generator was used incorrectly.
1039 This security bug affects only when encrypting with PKCS#1, and
1040 it is not currently used at all in SILC. SILC only use signing
1041 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1043 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1049 * Send the auto-nicking NICK command in client library with
1050 little timeout after connecting. The affected file is
1051 lib/silcclient/client.c.
1053 * Added following new config file settings:
1054 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1055 key_exchange_timeout, conn_auth_timeout, connections_max,
1058 Implemented all the new config settings handling in the server.
1060 Optimized the use of SKE Mutual flag usage. Use it only
1061 if connection authentication protocol is not based in public
1064 Renamed all SilcServerConfigSection* to SilcServerConfig*
1065 to have a bit shorter names.
1067 Affected files silcd/serverconfig.[ch], server.[ch], and
1070 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1092 section structs, now identifying the param directly.
1094 Added CONFIG_FREE_AUTH macro in config file parsing.
1096 Affected files are silcd/serverconfig.[ch].
1098 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1100 * Fixed command line parameter handling. All SILC initialization
1101 is now done in silc_core_init() which also fixes autoconnecting
1104 Affected files irssi/src/silc/core/silc-core.c,
1105 irssi/src/fe-text/silc.c.
1107 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1109 * Added new configuration options and blocks:
1110 keepalive_secs, reconnect_count, reconnect_interval,
1111 reconnect_interval_max, reconnect_keep_trying and
1112 require_reverser_lookup. Added ConnectionParam block, and
1113 implemented the connection parameters when connecting as
1114 initiator and when accepting connections as responder.

1117 whether given configuration value has been given already.
1119 Affected files silcd/serverconfig.[c], server.[c].
1121 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1122 algorithm parts and created new file silcalgs.conf, that
1123 is now included from the example_silcd.conf.in.
1125 * Optimized the silc_server_connect_to_router_second to take
1126 the connection configuration object from the SilcServerConnection
1127 object instead of finding it during the connecting phase.
1128 Added the configuration object to SilcServerConnection struct.
1129 Affected files silcd/server_internal.h, server.c.
1131 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1133 * Add the client on channel after it was resolved at the
1134 channel message receiving, and it was not already on the
1135 channel. Affected file lib/silcclient/client_channel.c.
1137 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1139 * Fixed the public key authentication to allocate always the

1151 * Added new Passphrase and Publickey authentication methods to
1152 config file, allowing both public key and passphrase based
1153 authentication to be set at the same time.
1155 Added `prefer_passphrase_auth' setting in config file which
1156 can be used to set to prefer passwd auth if both passwd and
1157 public key is set. If not set, public key is preferred.
1158 This has effect only when being initiator (responder will try
1161 Added support for authentication with passphrase and public key
1162 at the same time. The passphrase is tried first always since
1163 it is faster to check.
1165 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1167 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1169 * Merged the new SILC Config library, with the server parsing
1170 support. Read the header file silcconfig.h or the toolkit
1171 documentation for the news. Affected files are

1194 Payload. Affected file lib/silccore/silcchannel.c.
1196 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1197 as header filenames.
1199 * Removed lib/silcclient/README and created HTML file
1200 lib/silcclient/silcclient_using.html, which is now included
1201 as part of Toolkit documentation.
1203 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1205 * Fixed CUMODE_CHANGE notify handling to change the mode of
1206 correct client. Affected file lib/silcclient/client_notify.c.
1208 * Make silc_rng_alloc fail if it cannot allocate the sha1
1209 hash algorithm. Affected file lib/silccrypt/silcrng.c.

1213 * Fixed the file transfer's key agreement payload to include
1214 zero port also if the hostname is NULL because it could not
1217 Call file transfer monitor callback now also if error occurs
1218 during key agreement protocol.
1220 Changed the silc_client_file_send interface to return the
1221 SilcClientFileError instead of session id. The session ID
1222 is returned into pointer provided as argument.
1224 Check that the file exists locally before sending the
1225 file transfer request at all.
1227 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1229 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1230 error than can occur while key agreement protocol. Affected
1231 file lib/silcclient/silcapi.h.
1233 * Fixed the event_mode CMODE handler to not crash when mode
1234 is changed and +k mode is set in the channel. Affected file
1235 irssi/src/silc/core/silc-channels.c.
1237 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1238 SILC_LOG_WARNING to give out Warning and not Error. Affected
1239 file lib/silcutil/silclog.c.
1241 * Fixed the channel message payload decryption in the function
1242 silc_channel_message_payload_decrypt to not modify the original
1243 buffer before it is verified that the message decrypted
1244 correctly. Otherwise, next time it is called with correct
1245 channel key it won't encrypt since the payload is corrupted.
1246 Affected file lib/silccore/silcchannel.c.
1248 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1258 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1260 * Fixed a bug in hash table internal routine for traversing
1261 the table with foreach callback. The current entry may
1262 become invalid in the callback but it was referenced after
1263 the callback returned.
1265 Do not allow auto rehashing of hash table during the
1266 silc_hash_table_foreach operation, for same reasons as it is
1267 not allowed for SilcHashTableList. Affected files are
1268 lib/silcutil/silchashtable.[ch].
1270 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1273 Win32 DLL. extern's in header files are now declared with
1276 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1278 * Fixed private message handling. It used some old code that
1279 caused the client to crash. Affecte file is
1280 lib/silcclient/client_prvmsg.c.
1282 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1284 * Added function silc_client_add_channel,
1285 silc_client_replace_channel_id, and removed functions
1286 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1287 from client library.
1289 * Added cross reference of the joined channels to the
1290 SilcClientEntry, and changed the SilcChannelEntry's
1291 users list to SilcHashTable. The affected files are
1292 lib/silcclient/idlist.[ch].
1294 * Fixed a bug in hash table tarversing. While the hash table
1295 is traversed with SilcHashTableList the table must not be
1296 rehashed. It is now guaranteed that auto rehashable tables
1297 are not rehashed while tarversing the list. Also defined that
1298 silc_hash_table_rehash must not be called while tarversing
1299 the table. Added function silc_hash_table_list_reset that must
1300 be called after the tarversing is over. The affected files are
1301 lib/silcutil/silchashtable.[ch].
1303 * Changed all hash table traversing to call the new
1304 silc_hash_table_list_reset in server and in client library.
1306 * Added function silc_client_on_channel to return the
1307 SilcChannelUser entry if the specified client entry is joined
1308 on the specified channel. This is exported to application as
1309 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1311 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1313 * Fixed founder regaining problem with JOIN command on normal
1314 server. The notify for mode change must be sent always and
1315 not only if !cmd->pending. Affected file silcd/command.c.
1317 * Fixed the WHOWAS command's reply sending to support the
1318 lists correctly. Affected file silcd/command.c.
1320 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1322 * When sending JOIN command to router for processing the
1323 sender's old command identifier was not saved back to the
1324 sender's command context, fixed now. The affected file is
1327 * Create the key in JOIN command of the router did not return
1328 the channel key, added check for this. Affected file is
1331 * Fixed a channel ID update bug in JOIN command reply. Do
1332 not directly upgrade the ID but call the function
1333 silc_idlist_replace_channel_id if the ID was changed.
1334 Affected file silcd/command_reply.c.
1336 * Fixed memory leaks from command calling if it would fail.
1337 Affected file silcd/command.c.
1339 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1341 * Applied patches from cras:
1343 Memory leak fixes around libaries, irssi window resize fix,
1344 new silclist.h and silcdlist.h, all extern inline changed to
1347 * Removed dotconf from lib/dotconf, not needed anymore.
1349 * Removed TRQ from lib/trq, not needed anymore.
1351 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1352 with server connections. Later this will be configurable
1353 in config file after new config file is done. Affected file
1356 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed a crash in server related to channel announcements.
1359 Affected file silcd/server.c.
1361 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1363 * Fixed memory leaks in silc_server_create_new_channel*
1364 functions. Affected file silcd/server.c.
1366 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1367 which ID was changed. This way the router will send the
1368 user list for the channel again, and server won't be in
1369 desync in some rare circumstances. Affected file is
1370 silcd/packet_receive.c.
1372 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1374 * Check for NULL socket pointer in the function
1375 silc_server_packet_send_to_channel_real. Affected file

1383 * Fixed some header addition to Toolkit distribution in
1384 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1386 * Added lib/silcclient/client_ops_example.h as an template
1387 file for application programmers to quickly start using
1388 the SilcClientOperation functions in their application.
1389 Updated the lib/silcclient/README as well to tell about this
1390 nice file made available.
1392 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1394 * Call silc_server_remove_from_channels when removing client
1395 entry when NO_SUCH_CLIENT_ID was received. Affected file
1396 is silcd/command_reply.c.
1398 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1400 * Added server & router operator statistics updating. Affected
1401 file silcd/packet_receive.c and silcd/command.c.
1403 * Fixed the SERVER_SIGNOFF notify handling on normal server
1404 not to save the history information for clients. Same was
1405 fixed earlier in remove_clients_by_server function, but not
1406 here. Affected file silcd/packet_receive.c.
1408 * Raised the default connection-retry count from 4 to 7 in
1409 server. Affected file silcd/server.h.
1411 * Cancel any possible reconnect timeouts when we start the
1412 key exchange. Affected file silcd/server.c.
1414 * Do not reconnect on connection failure when SCONNECT was
1415 given. Affected files silcd/server.[ch].
1417 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1421 * Fixed the NICK command to always give the unformatted
1422 nickname to the one giving the NICK command. If unformatted
1423 nickname is cached already it will be formatted and the
1424 local entry will always get the unformatted nickname.
1425 Affected file lib/silcclient/idlist.c.
1427 * Fixed some double frees from client library commands.
1428 Affected file is lib/silcclient/command.c.
1430 * Fixed CUMODE command in server to assure that no one can
1431 change founder's mode than the founder itself, there was a
1432 little bug. Affected file silcd/command.c.
1434 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1436 * Removed the SilcClientCommandDestructor from the client
1437 libary, it is not needed anymore. Affected files are
1438 lib/silcclient/silcapi.h, command[_reply].[ch],
1439 client_notify, idlist.c.
1441 * Fixed GETKEY command to first resolve client, and then
1442 resolve the server only if the client was not found, instead
1443 of resolving both at the same time. Affected file is
1444 lib/silcclient/command.c.
1446 * Added silc_client_start_key_exchange_cb and lookup the
1447 remote hostname and IP address before starting the key
1448 exchange with server. The affected file is
1449 lib/silcclient/client.c.
1451 * The server's public key is now saved using the IP address
1452 of the server and not the servername for the filename.
1453 The hostname public key filename is checked as an fall back
1454 method if the IP address based filename is not found.
1456 Fixed the GETKEY command to save the fetched server key
1457 in correct filename.
1459 Print the remote server's hostname now when new key is
1460 received during connection process. Affected file is
1461 irssi/src/silc/core/client_ops.c.
1463 * Return always our own public key to the client if it asks
1464 for it with GETKEY command. Affected file silcd/command.c.
1466 * Removed the use_auto_addr variable from default config
1467 file since it was in wrong section. Affected file is
1470 * Fixed TOPIC_CHANGE notification to not route it when it
1471 was sent using silc_server_send_notify_to_channel function.
1472 Affected file silcd/command.c.
1474 * Fixed silc_server_send_notify_kicked to send the kicker's
1475 Client ID also, it was missing. Affected files are
1476 silcd/command.c, silcd/packet_send.[ch].
1478 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1480 * Do not save client history information in SERVER_SIGNOFF.
1481 Fixes the bug in normal server that it does not detect
1482 the client becoming valid after the server becomes back
1483 online. Affected file silcd/server_util.c.
1485 * Added `sock_error' field into the SilcSocketConnection
1486 context. When error occurs during socket operation (read
1487 or write) the error is saved. Added also new function
1488 silc_socket_get_error to return human readable socket error
1489 message. Affected files are lib/silcutil/silcsockconn.[ch],
1490 lib/silcutil/unix/silcunixsockconn.c, and
1491 lib/silcutil/win32/silcwin32sockconn.c.
1493 * The server now prints the socket error message in the
1494 signoff for client. Affected file silcd/server.c.
1496 * Fixed the `created' channel information sending from router
1497 to server in JOIN command. Checks now whether the channel
1498 really was created or not and set it according that.
1500 Fixed the JOIN command to use the client entry's current
1501 ID during the joining procedure instead of the one it sent
1502 in the command (it is checked though), since it can change
1503 between the packet processing and command processing, and
1504 would just case unnecessary pain in the client end. Affected
1505 file silcd/command.c.
1507 * Fixed a channel key payload sending to use correct channel
1508 ID when the server was forced to change the channel's ID by
1509 router. Router sent the key payload with the old Channel ID.
1510 Affected file silcd/packet_receive.c.
1512 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1514 * Call silc_server_save_channel_key only if the key payload
1515 was provided in the JOIN command's command reply. Affected
1516 file silcd/command_reply.c.
1518 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1520 * Fixed silc_mp_sizeinbase to return the value correctly with
1521 MPI. Affected file lib/silcmath/mp_mpi.c.
1523 * Fixed the stop_server signal to correctly stop the scheduler
1524 and gracefully stop the server when SIGTERM or SIGINT signals
1525 are received. Affected file silcd/silcd.c.
1527 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1529 * Simple handling of TERM and HUP signals. Also added some log
1530 flushing call around. Affected file is
1533 * Fixed small bugs in silclog.c. Now buffering output will take
1534 effect after 10 seconds since startup: This will ensure that
1535 no important startup messages are lost. Also output redirection
1536 will preserve original format ([Date] [Type] message).
1537 Affected file is lib/silcutil/silclog.c.
1539 * Added two options to the config file, in the logging section:
1540 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1541 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1543 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1545 * Do not print the warning about log files not being initialized
1546 more than once to avoid excess logging. Affected file is
1547 lib/silcutil/silclog.c.
1549 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1550 the SIM copying in make install in Makefile.am.pre.
1552 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1554 * Rewritten silclog APIs. Globally interesting changes follows:
1555 silc_log_set_files() changed to silc_log_set_file().
1556 silc_log_set_callbacks() changed to silc_log_set_callback().
1557 ROBOdoc documented silclog header file.
1558 SilcLogCb now returns bool to wether inihibit the default
1559 handler or not (to keep the old behaviour return always TRUE).
1560 The new APIs should also fix the problem of the
1561 silcd_error.log file that was written in the current directory.
1564 Log files streams will remain opened after silc_log_set_file()
1565 call, means less CPU usage notably on high traffic servers.
1566 File streams are now full buffered, and flushed to the disk
1567 every 5 minutes, lesses HD activity and CPU usage.
1568 Messages can be redirected, allowing admins to configure
1569 one single logfile for all server messages.
1570 the silc_log_quick global variable to activate fast-logging.
1571 Affected files lib/silcutil/silclog.[ch]
1573 * Changed some code to conform new silclog APIs. Affected
1574 files are doc/example_silcd.conf.in, silcd/server.c
1575 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1578 * Fixed a memory leak that could occur in some situations.
1579 Affected file silcd/serverconfig.c.
1581 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1583 * Added the silc_client_del_client to remove the client from
1584 all channels as well. Affected file lib/silcclient/idlist.c.
1586 * Fixed the client library to correctly remove the client
1587 from all channels when the client entry is being destroyed.
1588 Affected file lib/silcclient/client_notify.c, command.c.
1590 * Added auto-nicking support to the client library. If the
1591 applicatio now sets client->nickname it will be sent to the
1592 server after connecting by the library. This way for example
1593 SILCNICK (or IRCNICK) environment variables will have effect
1594 and always change the nickname automatically to whatever
1595 it is wanted. Affected file lib/silcclient/client.[ch].
1597 * Renamed silc_server_command_bad_chars to the
1598 silc_server_name_bad_chars and moved it to the
1599 silcd/server_util.[ch]. Added also new function
1600 silc_server_name_modify_bad to return nickname that
1601 includes bad characters as new nickname without those
1602 bad characters. This check and modify is now used in
1603 silc_server_new_client when the username is initially set
1604 as nickname, so it must be checked to be valid nickname.
1605 Affected file silcd/packet_receive.c.
1607 * The nickname length is now taken from the packet for real
1608 and not trusted to strlen() since it clearly can return
1609 wrong length for nickname including bad characters. This
1610 also applies to channel names. Affected file silcd/command.c.
1612 * Removed the lib/silcsilm/modules directory. Modules are now
1613 compiled into the lib/silcsim. Fixed the copying of the
1614 modules to follow symbolic links in Makefile.am.pre.
1616 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1618 * Fixed silc_string_regexify list creation. Fixes bugs with
1619 BAN and INVITE commands in server. The affected file is
1620 lib/silcutil/unix/silcunixutil.c.
1622 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Removed the command destructor entirely from the server's
1625 command and command reply routines. It is not needed, and
1626 its usage was buggy and caused crashes. Affected files are
1627 silcd/command[_reply].[ch].
1629 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Cancel protocol and NULL sock->protocol if timeout
1632 occurred during protocol. Affected file silcd/server.c.
1634 * Cancel protocol timeouts always before calling the final
1635 callback, to assure that after final callback is called
1636 no other state will be called for the protocol anymore.
1637 Affected file silcd/protocol.c.
1639 * Print error log if incoming connection configuration could
1640 not be found. Affected file silcd/server.c.
1642 * Fixed JOIN command to correctly save the founder mode
1643 to the client on normal SILC server, when the channel
1644 was created by the router. Affected file silcd/command.c.
1646 * Fixed LIST command (hopefully) to send correct reply
1647 packets. Affected file silcd/command.c.
1649 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * The silc_packet_receive_process now returns FALSE if the
1652 read data was invalid packet, and TRUE if it was ok.
1654 The server now checks that if unauthenticated connection
1655 sends data and its processing fails the server will close
1656 the connection since it could be a malicious flooder.
1658 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1660 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Make sure the warning about error opening a log file is
1663 printed only once and not everytime it fails (produces
1664 too much useless log). Affected file lib/silcutil/silclog.c.
1666 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1668 * Made the silc_server_daemonise() function more readable.
1669 Affected file silcd/server.c.
1671 * Pid file is now optional, the user may comment it out from
1672 the config file. Removed define SILC_SERVER_PID_FILE, we
1673 don't need a default any longer. Affected file
1674 configure.in.pre, lib/Makefile.am.pre.
1676 * Make some use of the pid file. The server now dies at startup
1677 if it detects a valid pid file on his path. The server would
1678 die anyway in this circumstance, because of the bind() failure.
1679 Affected file silcd/silcd.c.
1681 * No longer compiling lib/dotconf.
1683 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Fixed JOIN command parsing not to crash. Affected file
1686 lib/silcclient/command.c.
1688 * Fied the NICK_CHANGE notify to add the new client entry
1689 even it is resolved. This removes an <[unknown]> nick
1690 thingy bug in the client. Affected file is
1691 lib/silcclient/client_notify.c.
1693 * Do not try to allocate 0 bytes (efence does not like it)
1694 in lib/silccore/silccomand.c when encoding payload.
1696 * Do not take IRCNICK as nickname in Irssi SILC client since
1697 it is not possible to set nickname before hand connecting
1698 the server (TODO has an entry about adding auto-nicking
1701 * Changed the silc_server_command_pending to check whether
1702 there already exists an pending entry with the specified
1703 command, command identifier and pending callback. This is
1704 to fix IDENTIFY and WHOIS related crashes that may register
1705 multiple pending commands with same identifier. Affected
1706 file silcd/command.c.
1708 * Fixed the server to reconnect to the router even if it
1709 was already reconnecting and EOF was received. This to
1710 fix a possibility that the server wouldn't ever try to
1711 auto-reconnect to the router. Affected file silcd/server.c.
1713 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Fixed the server's password authentication to use the
1716 length of the locally saved password, and not the one
1717 sent in the packet. Affected file silcd/protocol.c.
1719 * Fixed same password authentication problem in the
1720 Authentication Payload handling routines in
1721 lib/silccore/silcauth.c.
1723 * Yet another password authentication problem fixed with
1724 channel password handling in silcd/command.c.
1726 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * If first character of string in silc_parse_userfqdn is '@'
1729 then do not parse it. Affected file is
1730 lib/silcutil/silcutil.c.
1732 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1734 * Fixed minor bug in IDENTIFY command reply sending, which
1735 caused various weird problems during JOIN when it was
1736 resolving names for users. Affected file silcd/command.c.
1738 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1740 * Fixed the IDENTIFY command reply sending to chech better valid
1741 clients. It was possible to send incomplete list of replies.
1742 Affected file silcd/command.c.
1744 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Added silc_client_command[s]_[un]register functions now to
1747 dynamically register the commands in client library. Removed
1748 the static table of commands. This allows the client library
1749 to call commands without causing the application to know about
1750 what commands library has called.
1752 Removed the INFO command reply kludge to detect when the command
1753 was called by library. Now library use its own command reply
1754 function for INFO command.
1756 Added function silc_client_command_call to call a command.
1757 Application can use it to call command, not access the structure
1760 Now all commands that are sent by the client library (not
1761 explicitly sent by application) use own command reply functions.
1763 Affected files around lib/silcclient/ and in
1764 irssi/src/silc/core/.
1766 * Fixed the WHOIS command reply sending to chech better valid
1767 clients. It was possible to send incomplete list of replies.
1769 Fixed the WHOIS and IDENTIFY to send the request to router
1770 if normal server did not do it and did not find any results.
1772 Affected file silcd/command.c.
1774 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Moved the internal data from SilcClient context into its
1777 own file, not accesible to application. Affected files
1778 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1779 and other files in client library.
1781 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Added doc/examples installation target in Makefile.am.pre.
1786 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1789 commands the found client entry will be removed from the
1790 cache, after notifying application about the error. Affected
1791 file lib/silcclient/command_reply.c.
1793 * Changed the /MSG to check for exact nickname user gave, and
1794 not let `nick' match `nick@host' if it is only one found. Now,
1795 user must type the exact nickname (like nick@host2) even if
1796 there are no more than one same nicks found. This is to avoid
1797 a possibility of sending nickname to wrong nickname since
1798 `nick' could match `nick@host'. Affected file is
1799 irssi/src/core/silc-servers.c.
1801 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1803 * Do not print "you are now server operator" or similar when
1804 giving /away command. Affected files are
1805 irssi/src/silc/core/client_ops.c, silc-servers.h.
1807 * Made the silc_server_command_pending_error_check to send
1808 the same command reply payload it received back to the
1809 original sender of the command. This way all arguments
1810 that was received by the server will be received by the
1811 client too. Affected file silcd/command.c.
1813 * Added the silc_idcache_add to return the created cache entry
1814 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1816 * Add global clients to expire if they are not on any channel.
1817 This is because normal server will never know if they signoff
1818 if they are not on any channel. The cache expiry will take
1819 case of these entries. This is done by normal servers only.
1820 The affected files are silcd/command_reply.c,
1821 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1823 * If server receives invalid ID notification for WHOIS or
1824 IDENTIFY and the ID exists in the lists, it is removed.
1825 Affected file silcd/command_reply.c.
1827 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1828 in client then client entry that it matches is searched and
1829 the nickname is printed on the screen for user. Affected
1830 file irssi/src/silc/core/client_ops.c.
1832 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Use cache entry expire time in the LIST command reply to
1835 purge old entries from the cache after the LIST command
1836 reply has been received. This way we don't have non-existent
1837 entries in the cache for too long. Affected file is
1838 silcd/command_reply.c.
1840 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * If we are normal server, and we've not resolved client info
1843 in WHOIS or IDENTIFY from router, and it is global client,
1844 we'll check whether it is on some channel. If it is not
1845 then we cannot be sure about its validity and will resolve it
1846 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1847 file silcd/command.c.
1849 * Search channel by name (if possible) rather than by ID
1850 in IDENTIFY command's command reply. Affected file is
1851 silcd/command_reply.c.
1853 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1856 Updated specs and implemented it. Affected file silcd/command.c,
1857 silcd/packet_send.c and silcd/packet_receive.c.
1859 * Implemented the <founder auth> payload handling in the JOIN
1860 command. If provided all conditions for channel joining
1861 except requirement to provide correct passphrase can be
1862 overrided by the channel founder. Updated the protocol specs.
1863 Affected file silcd/command.c.
1865 Added support for founder auth in JOIN command in client
1866 library. Fixed the parsing of the JOIN command now to support
1867 all options as they should be. The affected file is
1868 lib/silcclient/command.c.
1870 * Optimized the WHOIS and IDENTIFY commands to send the request
1871 to router only if it includes nicknames or other names. If
1872 they include only IDs then check the local cache first before
1873 routing. Affected file is silcd/command.c.
1875 * Added channels topic announcements. Affected file is
1876 silcd/packet_receive.c and silcd/server.c.
1878 * Fixed the silc_server_send_notify_topic_set to really destine
1879 the packet to channel. Affected file silcd/packet_send.c.
1881 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1882 library. Affected file lib/silcclient/client_notify.c.
1884 * Added UMODE announcements. Affected file silcd/server.c.
1886 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Memory leak fixes in:
1890 lib/silcutil/silcsockconn.c
1891 lib/silcske/silcske.c
1892 lib/silcske/groups.c
1894 lib/silccrypt/silcpkcs.c
1895 lib/silccore/silccommand.c
1896 lib/silccore/silcidcache.c
1901 * ROBOdoc documented the lib/silcske/groups.h file and a
1902 bit changed the interface for better.
1904 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1906 * Update the client entry context in the ID cache after
1907 nick change. Affected file lib/silcclient/command.c.
1908 Fixes the CUMODE command when regaining founder privileges,
1909 and a little WHOIS problem.
1911 * Fixed silc_net_gethostbyname to correctly call the
1912 inet_ntop. Affected file lib/silcutil/silcnet.c.
1914 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1916 * Added IPv6 support checking to the configure.in.pre, added
1917 also --enable-ipv6 option to override the check. Affected
1918 file configure.in.pre.
1920 * The silc_thread_create now calls the start function
1921 directly if threads support is not compiled in. Removes
1922 ugly #ifdef's from generic code. Affected files are
1923 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1925 * Added silc_net_gethostby[name/addr]_async to asynchronously
1926 resolve. Affected files are lib/silcutil/silcnet.[ch].
1928 * Added support for rendering IPv6 based server, client and
1929 channel IDs. Affected file lib/silcutil/silcutil.c.
1931 * Added support for creating IPv6 based server IDs. Affected
1932 file is silcd/serverid.c.
1934 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1936 * Added silc_net_gethostby[addr/name] into the
1937 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1938 routines. Added silc_net_is_ip[4/6]. Affected file is
1939 lib/silcutil/unix/silcunixnet.c. All routines that take
1940 address as argument now supports both IPv4 and IPv6 addresses.
1942 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1944 * Fixed LIST command reply sending in server. Affected file
1947 * Server now sends the kicker's client ID in the KICK notify
1948 to the kicked client. Affected file silcd/command.c.
1950 * The client library now parses the kickers client ID and
1951 UI displays it. Affected files lib/silcclient/client_notify.c
1952 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1954 * Made all payload parsing function prototypes consistent.
1955 They all take now const unsigned char * and uint32 pair as
1956 the payload data instead of SilcBuffer. Changes all around
1957 the source tree. Other unsigned char* -> const unsigned char*
1958 changes around the tree as well.
1960 * Optimized SFTP client and server packet sending not to
1961 allocate new buffer for each packet but to recycle the
1962 first allocated buffer. Affected files are
1963 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1965 * Optimized the SFTP client to use SilcList instead of
1966 SilcDList for requests, because it is faster. Affected file
1967 is lib/silcsftp/sftp_client.c.
1969 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1970 into lib/silccore/silcid.[ch].
1972 Renamed silcpayload.[ch] into silcargument.[ch].
1974 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * If client entry is deleted with active key agreement
1977 session, abort the session.
1979 The silc_client_abort_key_agreement now calls the completion
1980 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1982 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1985 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Don't use __restrict in older GCC's. Affected file is
1988 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1990 * silc_net_localhost now attempts to reverse lookup the
1991 IP/hostname. Affected file lib/silcutil/silcnet.c.
1993 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1994 command. It can be used to gain founder privileges at
1995 the same time when joining the channel.
1997 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1998 kicker's client ID as well. Updated protocol specs.
2000 Defined that the server must send SILC_COMMAND_IDENTIFY
2001 command reply with error status to client who sent
2002 private message with invalid client ID.
2004 Updated the protocol specification.
2006 * Added silc_server_send_command_reply to send any
2007 command reply. Affected file silcd/packet_send.[ch].
2009 * Added silc_id_payload_encode_data to encode ID payload
2010 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2012 * The server now send IDENTIFY command reply with error
2013 status if client ID in private message is invalid. Affected
2014 file silcd/packet_receive.c.
2016 * Save the server key file with server's IP address in
2017 the filename instead of hostname. The affected file is
2018 irssi/src/silc/core/client_ops.c.
2020 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2025 * Added libtool support for compiling shared objects in
2026 lib/silcsim. Affected file configure.in.pre and
2027 lib/silcsim/Makefile.am. Original patch by cras.
2029 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Pid file configuration, and server's config file fixes
2032 patch by toma. Updated CREDITS file.
2034 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2036 * Fixed silc_client_channel_message to not try to decrypt
2037 the message twice if it resolved the destination client
2038 information. This could cause of dropping one channel
2039 message. Affected file lib/silcclient/client_channel.c.
2041 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2044 lib/silcclient/client.c. This function is used when the SILC
2045 Client is run under some other scheduler, or event loop or
2046 main loop. On GUI applications, for example this may be
2047 desired to used to run the client under the GUI application's
2048 main loop. Typically the GUI application would register an
2049 idle task that calls this function multiple times in a second
2050 to quickly process the SILC specific data.
2052 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2054 * Fixed silc_server_drop() for dropping the supplementary
2055 groups as well, this could cause a security hole on some
2058 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2063 * Write PID file after dropping privileges. Added -F option
2064 to run server on foreground. A patch by debolaz.
2065 Affected files silcd/server.c, silcd/silcd.c.
2067 * Fixed MOTD to return the MOTD file server name. Affected
2068 file silcd/command.c.
2070 * Added INFO command reply handling to the Irssi SILC Client.
2071 Affected file irssi/src/silc/core/client_ops.c.
2073 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Fixed the silc_idcache_list_* routines to really support
2076 the dynamic list. Fixes a crash. Affected file is
2077 lib/silccore/silcidcache.c.
2079 * Fixed the LIST command reply to really call LIST command's
2080 pending callbacks. Affected file silcd/command_reply.c.
2082 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Update conn->local_entry->nickname after giving NICK
2085 command. Affected file lib/silcclient/command.c.
2087 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2089 * Added the [pid] option to the silcd configuration file
2091 Affected files: serverconfig.[ch] and silcd.c
2093 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Save fingerprint in WHOIS command reply in server.
2096 Affected file silcd/command_reply.c.
2098 * Fixed NICK commands pending callback registration.
2099 Affected file lib/silcclient/command.c.
2101 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Use ++server->cmd_ident when sending commands in server,
2104 instead of random number. Affected file silcd/command.c.
2106 * Fixed GETKEY command reply to call actually GETKEY pending
2107 command callbacks. Affected file silcd/command_reply.c.
2109 * A bit stricter check for nicknames. Check for same nickname
2110 in NICK command also. Affected file silcd/command.c.
2112 * Do not call INFO command everytime client ID changes, only
2113 during first connecting. Affected file lib/silcclient/client.c.
2115 * Set the new nickname only after successful command reply for
2116 NICK command is returned by server. Affected file
2117 lib/silcclient/command.c.
2119 * Remove nicknames from nicklist during server_signoff notify.
2120 Should fix /NAMES bit more. The affected file is
2121 irssi/src/silc/core/silc-channels.c.
2123 * Added `fingerprint' field to the SilcIDListData in the
2124 silcd/idlist.h to hold the fingerprint of the client's
2127 Send the fingerprint of the client's public key in WHOIS
2130 Affected files silcd/command.c, and silcd/idlist.[ch].
2132 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2133 create fingerprint from given data.
2135 * Show the fingerprint of the client's public key in WHOIS.
2136 Affected files irssi/src/module-formats.[ch] and
2137 irssi/src/silc/core/client_ops.c.
2139 * Format the multiple same nicknames also during JOIN and
2140 NICK_CHANGE notifys. Affected file is
2141 lib/silcclient/client_notify.c.
2143 * Do not print error on screen for invalid private message
2144 payload since it can come if someone is sending private
2145 messages with wrong key. Affected file
2146 lib/silccore/silcprivate.c.
2148 * Fixed multiple concurrent /PING crash. Affected file
2149 lib/silcclient/command.c.
2151 * Changed the wrong ID encoding. All IP addresses must be
2152 in MSB first order in encoded format. They were encoded
2153 wrong and was in LSB format. Affected files are
2154 silcd/serverid.c, lib/silcutil/silcutil.c.
2156 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2158 * Call the `connect' client operation through the scheduler
2159 in case of error. Affected file lib/silcclient/client.c.
2161 * Call the `failure' client operation even if the error
2162 occurred locally during a protocol. Affected file is
2163 lib/silcclient/protocol.c.
2165 * Added support of sending LIST command to router from normal
2166 server. This way normal server can get list of all channels
2167 in the network too. Fixed the channel list sending in the
2168 server too. Affected files are silcd/command.c, and
2169 silcd/command_reply.[ch].
2171 * Added silc_server_update_channels_by_server and
2172 silc_server_remove_channels_by_server. They are used during
2173 disconnection of primary router and in backup router protocol.
2174 Affected file silcd/server_util.[ch], silcd/server.c and
2175 silcd/server_backup.c.
2177 * Fixed channel adding to global list in IDENTIFY command
2178 reply in server. Affected file silcd/command_reply.c.
2180 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * If the incoming packet type is REKEY or REKEY_DONE process
2183 that packet always synchronously. Fixes yet another MAC
2184 failed error on slow (dialup) connections. Affected file
2185 lib/silcclient/client.c and silcd/server.c.
2187 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Call check_version SKE callback for initiator too. Affected
2190 file lib/silcske/silcske.c.
2192 * Implemented fix for security hole found in the SKE that was
2193 fixed in the specification few days back; the initiator's
2194 public key is now added to the HASH value computation.
2195 Added backwards support for the old way of doing it too, for
2196 old clients and old servers. Affected file is
2197 lib/silcske/silcske.c.
2199 * Enabled mutual authentication by default in SKE. If initiator
2200 is not providing mutual authentication the responder will
2201 force it. This will provide the proof of posession of the
2202 private key for responder. The affected files are
2203 lib/silcclient/protocol.c and silcd/protocol.c.
2205 * Do not cache anymore the server's public key during SKE.
2206 We do mutual authentication so the proof of posession of
2207 private key is done, and if the server is authenticated in
2208 conn auth protocol with public key we must have the public
2209 key already. Affected file silcd/protocol.c.
2211 * Added new global debug variable: silc_debug_hexdump. If
2212 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2213 file lib/silcutil/silclog.[ch].
2215 * Fixed compilation warning due to char * -> const char *.
2216 Affected files lib/silcutil/silcnet.h, and
2217 lib/silccore/silcauth.[ch].
2219 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Fixed CMODE command when new channel key was created. If
2222 the creation failed the old key was removed. Next time giving
2223 same command would crash the server since the old key was
2224 freed already. Affected file silcd/command.c.
2226 * Fixed the silc_server_announce_get_channels to not crash
2227 on reconnect. Affected file silcd/server.c.
2229 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Added silc_log_set_debug_string function to set a regex
2232 string to match for debug output. Only the function names,
2233 or filenames matching the given debug string is actually
2234 printed. This way it is possible to filter out those debug
2235 strings that user is not interested in.
2237 Fixed a bug in silc_string_regexify.
2239 Affected files lib/silcutil/silclog.[ch], and
2240 lib/silcutil/unix/silcunixutil.c.
2242 * Changed the -d options in both server and Irssi SILC client
2243 to take the debug string as argument. Affected files
2244 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2246 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Added silc_hash_babbleprint to create a Bubble Babble
2249 Encoded fingerprint. The encoding is developed by Antti
2250 Huima (draft-huima-babble-01.txt), and it creates human
2251 readable strings out of binary data. Affected file
2252 lib/silccrypt/silchash.[ch].
2254 * Print the babble print now in addition of fingerprint as well
2255 in Irssi SILC client. Affected files are
2256 irssi/src/fe-common/silc/module-formats.[ch],
2257 irssi/src/fe-common/silc/core/client_ops.c.
2259 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * Fixed a security problem found in SKE. The initiator's
2262 public key too is now added to the HASH hash value creation
2263 which is signed by the responder to create the SIGN value.
2264 This will prevent anyone in the middle to lie to the responder
2265 about the initiator's public key. If this is done now, the
2266 man in the middle will get caught. Updated the protocol
2269 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Better installation directory handling. Configure module
2272 paths and other paths automatically to example_silc* files
2273 in doc/. A patch by toma.
2275 * Fixed compiler warning from MPI library, and from SILC RNG.
2278 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2279 It can be configured with ./configure. A patch by toma.
2281 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Find correct make to use in prepare-clean. A patch by
2284 toma. Affected file prepare-clean.
2286 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2288 * Added irssi variables use_auto_addr, auto_bind_ip,
2289 auto_bind_port and auto_public_ip.
2291 * Changed the interface for silc_client_send_key_agreement
2292 in lib/silcclient/silcapi.h
2296 irssi/src/silc/core/silc-core.c
2298 lib/silcclient/silcapi.h
2299 irssi/src/silc/core/silc-channels.c
2300 lib/silcclient/client_keyagr.c
2303 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Added silc_pkcs_public_key_compare to compare two
2306 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2308 * Check that the client who set the founder mode on the
2309 channel is the same client that is giving the founder
2310 mode to itself. It is done by comparing the saved public
2311 key (it is saved even in the authentication is passphrase).
2312 Affected file silcd/command.c.
2314 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Do not process packet for disconnected socket connection.
2317 Affected file lib/silccore/silcpacket.c.
2319 * Process the DISCONNECT packet through scheduler in the
2320 client library. Affected file lib/silcclient/client.c.
2322 * Fixed the silc_client_packet_parse to not to increase
2323 the packet sequence number if the conn->sock and the
2324 current socket connection is not same. This can happen
2325 for example during key agreement when the conn includes
2326 multiple socket connections (listeners). Affected file
2327 lib/silcclient/client.c.
2329 * The sender of the file transfer request now provides also
2330 the pointer (listener) for the key exchange protocol. If
2331 the listener cannot be created then it sends empty key
2332 agreement and lets the receiver provide the listener.
2334 Added `local_ip' and `local_port' arguments to the
2335 silc_client_file_send. If they are provided they are used,
2336 if not then it will attempt to find local IP address, if
2337 not found or bind fails then the remote client will provide
2340 Affected files are lib/silcclient/client_ftp.c and
2341 lib/silcclient/silcapi.h.
2343 * Extended the FILE SEND command to support defining the
2344 local IP and port for key exchange listener. They are
2345 optional. Affected file irssi/src/silc/core/silc-servers.c.
2347 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Defined to WHOIS command reply the sending of fingerprint
2350 of the client's public key (if the proof of posession of the
2351 corresponding private key is verified by the server).
2352 Updated to the protocol specification.
2354 * Added support of receiving the client's public key's
2355 fingerprint in command reply in client library. Affected
2356 file is lib/silcclient/command_reply.c, and
2357 lib/silcclient/idlist.[ch].
2359 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * Do not send over 128 chars long nickname to the server
2362 in NICK command. Affected file lib/silcclient/command.c.
2364 * Do not send over 256 chars long channel names to the server
2365 in JOIN command. Affected file lib/silcclient/command.c.
2367 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Assure that silc_server_close_connection cannot be called
2370 twice for same socket context. Affected file is
2373 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Send error message to application if opening file for
2376 writing during file transfer fails. Affected file is
2377 lib/silcclient/client_ftp.c.
2379 Remove all file transfer sessions for a client that we're
2380 removing from ID cache.
2382 Affected file is lib/silcclient/client_ftp.c.
2384 * Fixed silc_net_addr2bin to return correct address. Affected
2385 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2387 * Fixed file transfer session removing on signoff notify.
2388 Affected file irssi/src/silc/core/silc-servers.c.
2390 * Added the SilcClientFileError to be returned in the monitor
2391 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2392 Affected file lib/silcclient/silcapi.h.
2394 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Fixed a crash in silc_client_ftp_free_sessions and
2397 silc_client_ftp_session_free_client. Affected file
2398 lib/silcclient/client_ftp.c.
2400 * Added `disabled' field in the SilcChannelEntry in the server
2401 to indicate if the server entry is disabled. Affected file
2402 silcd/idlist.h, silcd/command[_reply].c.

2411 * Fixed a crash in client resolving in client_prvmsg.c in
2412 client library. Affected file lib/silcclient/client_prvmsg.c.
2414 * Do not actually remove the client directly from ID cache
2415 during SERVER_SIGNOFF, but invalidate it. This way we
2416 preserve the WHOWAS info for the client. Affected file
2417 silcd/server_util.c.
2419 * Fixed SERVER_SIGNOFF notify handling in the server. The
2420 server is now able to process incoming SERVER_SIGNOFF notify
2421 for a server that it doesn't even know about. It will remove
2422 the clients provided in the notify. Affected file
2423 silcd/packet_receive.c.
2425 * Check for partial packet in data queue after every packet that
2426 was found from the queue. Return and wait for more data if
2427 there is partial data in queue. Affected file is
2428 lib/silccore/silcpacket.c.
2430 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Added SilcClietFileError enum to indicate error in
2433 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2434 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2435 Affected files lib/silcclient/silcapi.h and
2436 lib/silcclient/client_ftp.c.
2438 * Check that newsize in silc_buffer_realloc is larger than
2439 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2441 * Added better monitor of file transfers. It now monitors
2442 key agreement protocol during the file transfer too. Added
2443 error reporting too. Affected files
2444 irssi/src/silc/core/silc-servers.c,
2445 irssi/src/fe-common/silc/module-formats.[ch].
2447 * Wrote a help file for FILE command.
2449 * Added silc_rng_global_get_byte_fast to get not-so-secure
2450 random data as fast as possible. Random data is read from
2451 /dev/urandom if available and from the SILC RNG if not
2452 available. It is used in padding generation. Affected file
2453 lib/silccrypt/silcrng.[ch].
2455 * All packets in client library are now processed synchronously.
2456 Optimized packet processing a lot. Affected file
2457 lib/silcclient/client.c.
2459 * All server connection packets are processing synchronously
2460 now in server, to optimize packet processing. Affected file
2463 * Include files are installed now only in Toolkit distribution
2464 if make install is given. Affected files: all Makefile.am's.
2466 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Assure that silc_client_notify_by_server_resolve does not
2469 resolve the client information multiple times. If it cannot
2470 be found by the first it cannot be found at all. Affected
2471 file lib/silcclient/client_notify.c.
2473 * Fixed WHOWAS command reply calling. Affected file
2474 lib/silcclient/command_reply.c.
2476 * Removed all references to silc_idlist_get_client from the
2477 Irssi SILC client since that call is internal call used by
2478 the library. The Irssi SILC client will use now client
2479 retrieval functions found in silcapi.h.
2481 * Fixed a bug in resolving nickname info before sending
2482 private message. It used freed memory. Affected file
2483 irssi/src/silc/core/silc-servers.c.
2485 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Assure my_channels statistics cannot go negative in server.
2488 Affected files silcd/server.c, silcd/server_util.c.
2490 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2494 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Win32 Toolkit changes. Affected files

2500 lib/sftp/sftp_fs_memory.c.
2502 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Added silc_net_localip to return local host's IP address.
2505 Affected file lib/silcutil/silcnet.[ch].
2507 * If key exchange or rekey protocol is active for a connection
2508 parse all packets syncronously since there might be packets
2509 in packet queue that we are not able to process without first
2510 processing packets before them. Affected file silcd/server,
2511 lib/silcclient/client.c.
2513 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2514 whether library should continue processing the packet.
2515 Affected file lib/silccore/silcpacket.h.
2517 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2518 SilcSFTPMonitorData to SFTP server to monitor various
2519 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2520 lib/silcsftp/sftp_server.c.
2522 * Added silc_file_size to return file size. Affected file

2527 transmission. Affected file lib/silcclient/client_ftp.c,
2528 lib/silccilent/client.[ch].
2530 * Added new local command FILE to the Irssi SILC Client.
2531 It is used to perform the file transfer. It has subcommands
2532 SEND, RECEIVE, SHOW and CLOSE. Affected files
2533 irssi/src/silc/core/client_ops.c,
2534 irssi/src/silc/core/silc-server.[ch].

2543 * Renamed silc_file_read and silc_file_write to functions
2544 silc_file_readfile and silc_file_writefile. Added function
2545 silc_file_open and silc_file_close. Affected files
2546 lib/silcutil/silcutil.[ch].
2548 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Resolve the client info when received private message or
2551 channel message for a client which nickname we don't know.
2552 Affected files lib/silcclient/client_prvmsg.c and
2553 lib/silcclient/client_channel.c.
2555 * Do not crash in /KEY if client is not connected. Affected

2558 * Added SilcClientStatus field to the SilcClientEntry in the
2559 lib/silcclient/idlist.h.
2561 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2562 is incomplete and is being resolved, it won't be resolved
2565 Make sure also that USERS command reply does not resolve
2566 twice information. Affected file is
2567 lib/silcclient/command_reply.c.
2569 Make sure that silc_client_get_clients_by_list does not
2570 resolve twice same information.
2572 * Check for valid client->id in the silc_server_free_client_data.
2573 Affected file silcd/server.c.
2575 * Fixed /GETKEY nick@server not to crash if the server entry
2576 is not found. Affected file lib/silcclient/command.c.
2578 * Fixed the silc_server_check_cmode_rights to check the
2579 requested modes correctly. Affected file silcd/command.c.
2581 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * Better checks for non-printable chars in nick added.
2584 Affected file silcd/command.c.
2586 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Call the silc_server_udpate_servers_by_server in the
2589 primary router that comes back online in the backup resuming
2590 protocol. Otherwise it routes packets wrong. Affected file
2591 silcd/server_util.[ch], silcd/server_backup.c.
2593 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2596 lib/silcutil/silcbuffmt.[ch].
2598 * Redefined the SILC packet header to include the padding
2599 length. Affected file lib/silccore/silcpacket.[ch].
2601 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2602 length for maximum padding up to 128 bytes). Affected
2603 file lib/silccore/silcpacket.h.
2605 * Removed all backwards support for old 0.5.x MAC thingies.
2606 The SILC packet header change makes it impossible to be
2607 backwards compatible.
2609 * Send the ENDING packet with timeout in the backup resuming
2610 protocol. This is to assure that all routers has connected
2611 to the primary router. Affected file silcd/server_backup.c.
2613 * Changed the RNG to take the first IV from random data. It
2614 used to take it from zero actually. Changed the RNG also
2615 to use /dev/urandom during session. /dev/random is used
2616 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2618 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Changed the SILC packet header to have the first two bytes
2621 (the packet length) encrypted. Affected files aroung the
2622 code tree, lib/silccore/silcpacket.[ch]. Removed the
2623 SilcPacketCheckDecrypt callback. It is not needed anymore
2624 since the silc_packet_receive_process will determine now
2625 whether the packet is normal or special.
2627 * Implemented the unidirectional MAC keys. Affected files
2628 lib/silcske/silcske.c, silcd/protocol.c and
2629 lib/silcclient/protocol.c.
2631 * Implemented the packet sequence number to the MAC computation.
2632 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2633 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2634 lib/silcclient/protocol.c.
2636 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Allow backup router to announce servers. All servers
2639 announced by backup router are added to the global list
2640 automatically. Update hte server's socket to our primary
2641 router also when backup router announces a server.
2642 Affected file silcd/packet_receive.c.
2644 * Do not update the client->router in the function
2645 silc_server_udpate_clients_by_server if the client is on
2646 global list. We might fail to find any specific server
2647 for locally connected clients and local cell clients. They
2648 should still use the `from' and not `to' as client->router.
2649 This fixes backup router resuming protocol. Affected file
2650 silcd/server_util.c.
2652 * Decrease channel statistics count only if the channel
2653 deletion worked. Affected files are silcd/server.c and
2654 silcd/server_util.c.
2656 * Added silc_server_update_servers_by_server to update origin
2657 of all server entries. Used during backup router protocol.
2658 Affected files silcd/server_util.[ch], silcd/server.c. and
2659 silcd/backup_router.c.
2661 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2662 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2663 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2664 lib/silccrypt/silchmac.c.
2666 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Assure that router cannot reroute the same channel message
2669 to the sender. Affected file silcd/packet_receive.c.
2671 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Made better checks that the channel message is not sent
2674 to the router it came from. Affected file is
2675 silcd/packet_send.c. Fixed memory leak too.
2677 * Announce informations for incoming router connection, but
2678 only after checking if it is replaced by backup router.
2679 Affected file silcd/packet_receive.c.
2681 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Fixed the backup resuming protocol to work in multiple
2684 router environment. Affected file silcd/server_backup.c.
2686 * Route packet only to one router in the function
2687 silc_server_packet_send_to_channel. Affected file is
2688 silcd/packet_send.c.
2690 * Fixed silc_server_send_notify_dest to set the broadcast
2691 flag. Fixed the silc_server_send_notify_topic to actually
2692 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2693 Affected file silcd/packet_send.c.
2695 * Changed the SFTP Filesystem interface. Changed the
2696 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2697 the filesystem operation function. The SilcSFTPFilesystem
2698 is now a context that is allocated by all filesystem allocation
2699 functions and it already includes the operations structure
2700 and filesystem specific context. It is given as argument
2701 now to the silc_sftp_server_start. This made the interface
2702 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2703 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2705 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Changed the backup router adding and getting interfaces
2708 in the server. The router that will be replaced by the
2709 specified backup router is now sent as argument. Affected
2710 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2713 * Added silc_net_addr2bin_ne to return the binary form of
2714 the IP address in network byte order. Affected files
2715 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2717 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * Check for existing server ID in silc_server_new_server
2720 and in silc_server_connect_to_router_final and remove the
2721 old entry if it exists. Affected file silcd/packet_receive.c,
2724 * Send the channel message always to only one router, either
2725 in upstream or downstream. Affected file is
2726 silcd/packet_send.c.
2728 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2730 * Wrote the definition of the backup resuming protocol to the
2731 protocol specification.
2733 * Removed one redundant channel key generation from normal
2734 server during joining procedure. Removed one redundant
2735 channel key sending from server to router during joining
2736 procedure. Affected file silcd/command.c.
2738 * Made minor bugfixes to the backup router resuming protocol.
2739 Affected file silcd/server_backup.c, server.c.
2741 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Added --disable-asm configuration option. Affected files
2744 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2747 * Implemented the backup resuming protocol that is used to
2748 resume the primary router position in the cell after the
2749 primary router comes back online. Affected files
2750 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2751 and silcd/server_util.[ch].
2753 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Sleep two (2) seconds after sending QUIT command to server.
2756 Affected file lib/silcclient/command.c.
2758 * Assure that if outgoing data buffer is pending do not force
2759 send any data. Affected file silcd/packet_send.c.
2761 * Assure that if outgoing data buffer is pending do not force
2762 send any data. Affected file lib/silcclient/client.c.
2764 * Implemented the backup router support when the primary router
2765 goes down. The servers and routers can now use the backup
2766 router as new primary router without loosing connectivity.
2768 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2771 in the server to indicate disabled entry. All data read
2772 from the connection will be ignored and no data is sent
2773 for entry that is disabled. Affected files are
2774 silcd/idlist.h, silcd/server.c.
2776 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Created SFTP client and server test programs in the
2779 lib/silcsftp/tests directory.
2781 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Implemented memory filesystem (virtual filesystem) for
2784 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2787 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Implemented the SFTP (SSH File Transfer Protocol) to the
2790 lib/silcsftp. It includes SFTP client and SFTP server
2793 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2795 * Moved lib/silccore/silcprotocol.[ch] to the
2796 lib/silcutil library.
2798 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2799 take variable argument list pointer as argument. Affected
2800 file lib/silcutil/silcbuffmt.[ch].
2802 * Added silc_buffer_set function that is used to set data
2803 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2804 Affected file lib/silcutil/silcbuffer.h.
2806 * Changed various routines in the core library to use the new
2807 silc_buffer_set instead of allocating new buffer only for
2810 * Added 64-bit value formatting and unformatting support to the
2811 silc_buffer_[un]format routines. Affected file is
2812 lib/silcutil/silcbuffmt.[ch].
2814 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2815 to includes/bitmove.h.
2817 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Fixed channel user mode saving in client library. Affected
2820 file lib/silcclient/command[_reply].c.
2822 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2824 * Defined the file transfer to the SILC Protocol. Added
2825 new packet type SILC_PACKET_FTP and defined File Transfer
2826 Payload. The mandatory file transfer protocol is SFTP
2827 (SSH File Transfer Protocol). Affected file in addition
2828 of the internet draft is lib/silccore/silcpacket.h.
2830 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2831 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2832 is used as part of backup router protocol when the primary
2833 router of the cell is back online and wishes to resume
2834 the position as primary router.
2836 * Redefined the MAC generation keys in the protocol. The
2837 same key is not used anymore in both direction. Both
2838 direction will now use different keys for sending and
2839 receiving. This fixes a potential security flaw. This
2840 change causes incompatibilities in the protocol.
2842 * Redefined also the MAC computation from the packet.
2843 An packet sequence number is now added to the MAC
2844 computation. This prevents possible replay attacks against
2845 the protocol. This change too causes incompatibilities
2848 Added `sequence' field to the SilcPacketContext to hold
2849 the current sequence number for the packet.
2851 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Added `created' field to the SilcIDListData in the file
2854 silcd/idlist.h to indicate the time when the entry was
2857 * Added `created' field to the SilcChannelEntry too. Affected
2858 file silcd/idlist.h.
2860 * Added `creation_time' aguments to all the announcement functions
2861 in the server. If it is provided then only the entries that
2862 was created after the provided time frame are actually
2863 announced. Affected file silcd/server.[ch].
2865 * The protocol says that the Channel ID's IP address must be
2866 based on the router's IP address. Added check for this in
2867 the silc_server_new_channel when processing incoming New Channel
2868 Payload. Affected file silcd/packet_receive.c.
2870 * Print out the correct version with --version in SILC client.
2871 Affected file irssi/src/silc/core/silc-core.c.
2873 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Fixed WHOWAS command to check for completnes of the client
2876 entry always, not just when the command is coming from client.
2877 Affected file silcd/command.c.
2879 * Added new function silc_server_packet_queue_purge to purge the
2880 outgoing data queue to the network. After the function returns
2881 it is guaranteed that the outgoing packet queue is empty.
2882 Affected file silcd/packet_send.[ch].
2884 * Purge the outgoing packet queue in the rekey protocol's final
2885 callback to assure that all rekey packets go to the network
2886 before quitting the protocol. Affected file silcd/server.c.
2888 * Added silc_client_packet_queue_parse as similar function as
2889 in server to the client library. The affected file is
2890 lib/silcclient/client.c.
2892 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Splitted silcd/server.c and created silcd/server_util.[ch]
2895 for utility functions.
2897 * Added new socket flag SILC_SF_DISABLED to indicate that the
2898 connection is open but nothing can be sent to or received from
2899 the connection. Affected file lib/silcutil/silsockconn.[ch].
2900 The checking for disabled socket is checked in the low level
2901 silc_socket_write and silc_socket_read functions.
2903 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Allow only nicknames and channel names that fits into the
2906 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2908 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * When processing JOIN command reply in server check that if
2911 the channel exists in our global list we'll move it the local
2912 list. Affected file silcd/command_reply.c.
2914 * Fixed the check whether client is joined on the channel already
2915 in JOIN command. Affected file lib/silcclient/command.c.
2917 * Fixed the JOIN command reply to check whether the channel
2918 already exists. Affected file lib/silcclient/command_reply.c.
2920 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Added silc_ske_status_string to map the SKE error numbers
2923 to readable strings. The affected files are
2924 lib/silcske/silcske[_status].[ch].
2926 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Do not show the private channels on the WHOIS channel list
2929 as it is not allowed by the protocol. The affected file is
2932 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Assure that the packet length digged from the actual packet
2935 is something sensible in the silc_packet_decrypt_rest_special
2936 in lib/silccrypt/silcpacket.c.
2938 * Free and NULL the allocated pointer in silc_hmac_alloc if
2939 the HMAC allocation fails. The affected file is
2940 lib/silccrypt/silchmac.c.
2942 * Print the selected security properties to the log files in
2943 the server. Affected file silcd/protocol.c.
2945 * Add SKE's reference counter even if calling the completion
2946 callback manually. Otherwise it goes negative, although it
2947 does not cause any problems. The affected file is
2948 lib/silcske/silcske.c.
2950 * Remove the client entry with short timeout after giving the
2951 KILL command. Affected file lib/silcclient/command.c.
2953 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2954 case all found clients are already disconnected (WHOWAS would
2955 found them) in the server. Affected file silcd/command.c.
2957 * Update the last_receive (time of last data received) to be
2958 updated only when received private or channel message so that
2959 the idle time showed in WHOIS makes more sense.
2961 * Added boolean field `valid' in to the SilcClientEntry in the
2962 client library to indicate whether the entry is valid or not.
2963 This fixes the nickname change bug on channel when changing
2964 the nickname to be same than the old (like nick to Nick) the
2965 nickname formatter doesn't set the new nick anymore to Nick@host.
2966 Affected file lib/silcclient/idlist.[ch].
2968 * Now actually fixed the nickname changing on disconnection.
2969 Added new function silc_change_nick to the Irssi SILC Client.
2970 Affected file irssi/src/silc/core/client_ops.c,
2971 irssi/src/silc/core/silc-nicklist.[ch].
2973 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Check that the public key exists in the GETKEY command before
2976 trying to encode it. Affected file silcd/command.c.
2978 * Print some notifications on received public keys with GETKEY
2979 command in the Irssi SILC Client. Affected files are
2980 irssi/src/fe-common/silc/module-formats.[ch],
2981 irssi/src/silc/core/client_ops.c.
2983 * Use IDENTIFY command to resolve the server information in the
2984 GETKEY command instead of INFO command. Affected file
2985 lib/silcclient/command.c.
2987 * All command reply functions in the client library now calls
2988 the pending command reply callbacks even if an error has
2989 occurred. The server has done this a long time and now it was
2990 time to move the client library to this as well. Now all
2991 errors can be delivered back to the pending command reply
2992 callbacks if necessary. Affected files are
2993 lib/silcclient/command[_reply].[ch].
2995 * Change the nickname on disconnection back to the username
2996 because in reconnect the server will enforce it to it anyway.
2997 Affected file irssi/src/silc/core/silc-servers.c.
2999 * Fixed a config file parsing bug in the Irssi SILC client.
3000 Affected file irssi/src/silc/core/clientconfig.c.
3002 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * When printing the channel mode on JOIN, verify that the
3005 channel key and channel's HMAC are valid. Affected file
3006 irssi/src/silc/core/client_ops.c.
3008 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3011 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3012 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3014 * Removed channel key rekey task deleting from the function
3015 silc_server_save_channel_key. Affected file silcd/server.c.
3016 Added explicit timeout task context instead that is used to
3017 delete the task if we are registering a new task before the
3018 new task has elapsed.
3020 * When channel key rekey occurs the client library now saves
3021 the old channel key for a short period of time (10 seconds) and
3022 is able to use it in case some is still sending channel
3023 messages encrypted with the old key after the rekey. Affected
3024 file lib/silcclient/[idlist.h|client_channel.c].
3026 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Added check to the silc_server_new_id_real to not accept
3029 new ID if it is the sender's own ID. Affected file is
3030 silcd/packet_receive.c.
3032 * Assure that we do not announce ourself or the one we've
3033 sending our announcements when we're router and are announcing
3034 servers to our primary router. Affected file silcd/server.c.
3036 * Fixed silc_server_command_identify_check_client to assemble
3037 correct WHOIS packet. It send corrupted WHOIS packet and
3038 caused problem with router to router connections. Affected
3039 file silcd/command.c.
3041 Fixed also silc_server_command_whois_check the same way
3042 as for the IDENTIFY command.
3044 * Added new SilcIDListStatus to the server in the SilcIDListData
3045 structure. The status now includes the current status of
3046 the entry (like registered, resolved etc.). Affected file
3047 silcd/idlist.[ch]. Defined a bunch of different status types
3048 as well. This replaced the old boolean registered field as well.
3050 Added resolve_cmd_ident field to the SilcClientEntry structure
3051 too so that if the entry is for example being resolved so
3052 another command may attach to the same pending command reply
3053 without requiring to resolve the same entry again. This concept
3054 should optimize the WHOIS and the IDENTIFY resolving under
3055 heavy load by taking away unnecessary resolving for entries
3056 that are being resolved already.
3058 Added support for adding multiple pending commands for one
3059 command idenfier. Affected file silcd/command[_reply].[ch].
3061 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3062 before deleting the data. Otherwise the hash table will have
3063 freed data in comparison functions. Affected file is
3064 silcd/command_reply.c.
3066 * Fixed silc_idlist_replace_client_id to add the new entry to
3067 the cache with NULL nickname. Otherwise there will be invalid
3068 memory as the nickname after the nickname is freed. Affected
3069 file silcd/packet_receive.c.
3071 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3072 saved into wrong slots because the previous number of entries
3073 was not taken into account. Affected file silcd/idlist.c.
3074 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3076 * If we are router and we receive JOIN notify to a channel that
3077 does not have any users then notified client is marked as the
3078 channel founder, as it is it. The affected file is
3079 silcd/packet_receive.c
3081 * Added to the extended hash table API's table_del_*ext functions
3082 the destructor as argument too, so that the caller can decide
3083 which destructor to use or whether to use destructor at all.
3084 Affected file lib/silcutil/silchashtable.[ch].
3086 * Fixed ID Cache purging. It actually deleted the entries from
3087 the hash table after the data was freed. The hash table ended
3088 up comparing freed memory. The affected file is
3089 lib/silccore/silcidcache.c.
3091 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Fixed Irssi SILC client's KILL command's HELP syntax.
3095 * The USERS command now resolves the detailed user information
3096 if the userinfo field is missing. Affected file is
3097 lib/silcclient/command_reply.c.
3099 * Do not print error in silc_file_read if the read file does
3100 not exist. Just silently return NULL. Affected file is
3101 lib/silcutil/silcutil.c.
3103 * Fixed the silc_log_output to not wine about NULL filename
3104 and to not create some bogus " " filename. Affected file is
3105 lib/silcutil/silclog.c.
3107 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Fixed various printing bugs on the user interface in the
3110 Irssi SILC Client. Minor changes that were forgotten from
3113 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Fixed the configure.in.pre and the compilation and distribution
3116 environment to support the new autoconf 2.52. That version is
3117 now required to compile the CVS trunk.
3119 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3122 to generally parse user@fqdn format strings. Affected file
3123 lib/silcutil/silcutil.c.
3125 * Added nickname_format and nickname_force_format fields to the
3126 SilcClientParams structure. The first one defines the format
3127 for the nicknames that the library will enforce if the receives
3128 multiple same nicknames. The second one is boolean value and
3129 can be used to force the library to always enforce the format
3130 to the nicknames regardles whether there are multiple nicknames
3131 or not. This configurable formatting was employed to flexibly
3132 support accessing multiple nicknames from the user interface.
3133 The userinterface can now set the nicknames to what ever format
3134 they prefer. Affected file lib/silcclient/silcapi.h.
3136 Added function silc_client_nickname_format to the file
3137 lib/silcclient/idlist.c. It performs the nickname formatting.
3139 Added new field `hostname´ to the SilcClientEntry context.
3140 It holds the hostname of the client. Affected file is
3141 lib/silcclient/idlist.h.
3143 * Irssi SILC Client sets the nicknames in nick@hostn format.
3144 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3145 irssi/src/silc/core/silc-core.c.
3147 The WHOIS printing now also shows both the real nickname and
3148 the formatted nickname so that user knows how to access the
3149 user if there are multiple same nicknames cached. Affected
3150 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3151 printing formatting too to take the hostname now as a separate
3152 argument. The Affected file is
3153 irssi/src/fe-common/silc/modules-formats.[ch].
3155 * Changed the silc_client_get_clients_local to accept the formatted
3156 nickname as argument. It accepts the real nickname too but the
3157 formatted nickname can be used to find the true entry from
3158 multiple entries. Affected file lib/silcclient/silcapi.h and
3159 lib/silcclient/idlist.c.
3161 * Added nickname_format_parse field to the SilcClientParams.
3162 It is a callback function provided by the application to parse
3163 the nickname out of the formatted nickname string. The library
3164 calls it to get the nickname from the formatted string. Since
3165 the application generally knows better the format of the nickname
3166 string it parses it instead of the library, even though library
3167 encodes the formatted string. If the callback function is not
3168 provided then the library will use the string as is. The
3169 affected file is lib/silcclient/silcapi.h.
3171 * All the nickname strings passed to the client library in
3172 commands are now expected to be formatted nickname strings.
3173 If the command does not support the formatted nickname string
3174 it will assume that the sent string is the actual nickname.
3175 Affected file lib/silcclient/command.c.
3177 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Added public key authentication support to OPER and SILCOPER
3180 commands in the client library. Affected file is
3181 lib/silcclient/command.c.
3183 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Changed the get_auth_methdod client operation to be asynchronous.
3186 It can be async if the application resolves the authentication
3187 method from the server during the negotiation. Added new
3188 SilcGetAuthMeth completion callback that the application will
3189 call after resolving the authentication method.
3191 Added function silc_client_request_authentication_method that
3192 the application can use to resolve the authentication method
3193 from the server. Added also SilcConnectionAuthRequest callback
3194 that the library will call after the server has replied. The
3195 application can call this function if it does not know the
3196 current authentication method.
3198 Affected files are lib/silcclient/client.c and
3199 lib/silcclient/silcapi.h.
3201 * The Irssi SILC client now automatically resolves the authentication
3202 method incase any configuration information is not present (and
3203 currently there never is). The affected file is
3204 irssi/src/silc/core/client_ops.c.
3206 * Fixed public key authentication from the client library.
3207 Affected file lib/silcclient/protocol.c. Changed also the
3208 protocol specification about the public key authentication in
3209 the connection authentication protocol. The actual data to be
3210 signed is now computed with a hash function before signing.
3212 * Fixed the public key authentication from the server as well.
3213 Affected file silcd/protocol.c.
3215 * Removed the mlock()'s from the memory allocation routines.
3216 Affected file lib/silcutil/silcmemory.c. The ./configure does
3217 not check anymore for the mlock(). Affected file is
3220 * Fixed USERS command in server to allow the execution of the
3221 command for private and secret channels if the client sending
3222 the command is on the channel. Affected file silcd/command.c.
3224 * Fixed silc_client_get_clients_local to return the clients
3225 count correctly. It could return wrong value. Affected file
3226 lib/silcclient/idlist.c.
3228 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3230 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3231 types. The assembler optimizations seemed not to like 64-bit
3232 data types. The assmebler optimizations thus are now enabled
3233 also for BSD systems as opposed to only enable them for Linux.
3235 * Do not check for threads at all on BSD systems. Affected
3236 file configure.in.pre.
3238 * Removed -n and -h options from the Irssi SILC Client since
3239 they are not used in silc.
3241 * Fixed the prime generation to assure that the first digit
3242 of the generated random number is not zero since our conversion
3243 routines does not like number strings that starts with zero
3244 digit. If zero digit is seen the random number is regenerated.
3245 This caused some corrupted RSA keys when the zero first digit
3246 was met. Affected file lib/silcmath/silcprimegen.c.
3248 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * Fixed WIN32 configuration in the ./configure script.
3251 Fixed to include xti.h on environments that has it.
3252 Patches by Carsten Ilchmann and andrew.
3254 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3256 * Changed the silc_id_create_client_id to be collision
3257 resistant. It is now assured that there cannot be created
3258 two same client ID's. I suspect that some weird bugs in
3259 the server were actually caused by duplicate Client IDs.
3260 Affected file silcd/serverid.[ch]. A router receiving
3261 new ID now also assures and informs the sending server
3262 if the ID caused collision.
3264 * Changed the silc_id_create_channel_id to also assure that
3265 there are no collisions.
3267 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Statement about ignoring the Mutual Authentication flag when
3270 performing rekey with PFS was a bit misleading. It is ignored
3271 if it was set in the initial negotiation, it cannot be even
3272 set in the rekey. Fixed in the ke-auth draft. Started the
3273 new versions of the protocol drafts in the doc/.
3275 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Fixed a bug in silc_client_command_identify_save when saving
3278 new channel information. The channel name was no duplicated
3279 and caused crash on exit. Affected file is
3280 lib/silcclient/command_reply.c.
3282 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Fixed the getkey command handling in the server. Send just
3285 empty OK reply to the sender if the key could not be fetched
3286 (but everything else was ok, like the key just was not available).
3287 Changed the public key parameter to optional in the protocol
3288 specs so that empty OK reply can be sent. Affected file
3291 Added a message to Irssi SILC client to tell to user if the
3292 server did not return a public key.
3294 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Fixed a channel key regeneration bug. It registered new
3297 timeout tasks exponentially until all system resources were
3298 used. Affected file silcd/server.c.
3300 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3302 * Added the SILC Document generator to the scripts/silcdoc.
3303 It can be used to generate the Toolkit Reference Manual out
3304 of the source tree. Internally it will also use the RoboDoc
3305 generator now imported in util/robodoc.
3307 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3309 * Added couple of return's in rekey protocol if error orccurred
3310 during the protocol. The execution must be terminated.
3311 Affected file silcd/protocol.c. Also, terminate the protocol
3312 always with timeout.
3314 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * The client's Client ID was created initally from the wrong
3317 nickname (it could have been in format nick@host) in the
3318 silc_server_new_client. Affected file silcd/packet_receive.c
3320 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Added some SILC_LOG_ERROR's to various error conditions
3323 if client could not be added to ID cache. Affected files
3324 silcd/packet_receive.c and silcd/server.c.
3326 * When client's sock->user_data is freed, NULL also the
3327 client->router and client->connection pointers. Added check
3328 for these pointers being NULL to various places around the
3329 code. Affected file silcd/server.c.
3331 * Added client->data.registered == TRUE checks to various
3332 places around the code to assure that unregistered client's
3333 are not handled when it is not allowed. Affected file
3336 * Added `bool registered' fields to all
3337 silc_idlist_[server|client]_get_* routines to indicate whether
3338 the fetched client needs to be registered or not. Affected
3339 file silcd/idlist.[ch].
3341 * Add your own entry as registered to the ID cache in the
3342 server. Affected file server.c.
3344 * Fixed a bug in silc_server_new_server. The SilcServer was
3345 set as the new server's context instead of SilcServerEntry.
3346 This naturally caused some weird bugs.
3348 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3350 * Do not delete the channel rekey task when adding it
3351 for in silc_server_create_channel_key.
3353 * Changed the silc_server_create_channel_key to return
3354 TRUE or FALSE to indicate the success of the channel key
3357 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Fixed MSVC++ project files and added missing files to
3360 Makefiles under win32/.
3362 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * Do not add TCP_NODELAY flag if the operating system
3365 does not have it defined. Affected files are
3366 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3368 * Fixed buffer overflow from Irssi SILC Client. Affected
3369 file irssi/src/fe-common/core/themes.c.
3371 * Fixed double free in client library in the file
3372 lib/silcclient/client.c when disconnecting from server.
3374 * Applied double free patch from cras to Irssi SILC client.
3375 Affected files irssi/src/core/[modules/expandos].c
3377 * Fixed the disconnection handling to Irssi SILC Client.
3378 The application must call silc_client_close_connection
3379 in ops->connect client operation in case of failure of
3380 the connection. Affected file is
3381 irssi/src/silc/core/client_ops.c.
3383 * Do not set sock->protocol to NULL in the function
3384 silc_client_close_connection after executing the protocol's
3385 final callback since the sock might not be valid anymore.
3386 Affected file lib/silcclient/client.c.
3388 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Do not enable SILC_THREADS if the linking with libpthread
3391 did not happen. Affected file configure.in.pre.
3393 * Added notion to protocol specification that server must
3394 verify the sent authentication payload with CMODE when
3395 setting the channel founder key. Implemented it to the
3396 server. Affected file silcd/command.c.
3398 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Added _EXTRA_DIST SILC distribution variable to the
3401 distributions file. It is used to conditionally add extra
3402 files or directories to the specific distribution. Affected
3403 files ./prepare, Makefile.am.pre and distributions.
3405 Removed the `_' from the start of the distribution names.
3408 * Added README.WIN32 for instructions to compile the Toolkit
3411 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * Fixed a double free in disconnection in the server. Affected
3414 file is silcd/server.c.
3416 * Fixed the lib/silcske/groups.c to work now also with GMP
3417 MP library. The string conversion did not work when using
3418 specific base and the base is indicated in the string as well.
3420 * Created win32/ directory which now includes MSVC++ specific
3421 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3422 It will appear only in the toolkit distribution
3424 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3426 * Changed the key material distribution function in case when
3427 the hash output is too short. The data is now concatenated
3428 a bit differently than it used to. Made the change to the
3429 SKE protocol specification.
3431 * Added better GMP detection to configure.in.pre. A patch
3434 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Fixed a minor bug in SKE that might cause some problem on
3437 some platforms. Affected file lib/silcske/silcske.c.
3439 * Added the cookie checking for initiator in the SKE. It checks
3440 that the responder returns the sent cookie unmodified. The
3441 affected file is lib/silcske/silcske.c. Added new SKE
3442 error type INVALID_COOKIE that can be sent during the
3443 negotiation. Fixed some memory leaks as well.
3445 * Added the "invalid cookie" error message to Irssi SILC client's
3448 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Added `task_max' field to the SilcClientParams to indicate
3451 the maximum tasks the scheduler can handle. If set to zero,
3452 default values are used. Affected file lib/silcclient/silcapi.h.
3454 * Fixed memory leaks in silc_client_close_connection. Affected
3455 file lib/silcclient/client.c.
3457 * Added silc_client_del_client_entry to client library to free
3458 all memory of given client entry. Affected file is
3459 lib/silcclient/idlist.[ch].
3461 * Added new functions silc_client_del_channel and
3462 silc_client_del_server to delete channel and server entries.
3463 Affected file lib/silcclient/[silcapi.h/idlist.c].
3465 * Removed silc_client_del_client_by_id from silcapi.h.
3467 * Fixed the INFO command to return the server's own info
3468 correctly when querying by Server ID. Affected file is
3471 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Removed the non-blocking settings in WIN32 code in the
3474 silc_sock_[read/write] and added SleepEx instead. Affected
3475 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3476 of input data is now checked with FIONREAD and ioctlsocket.
3478 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Call silc_schedule_task_del_by_context in the
3481 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3482 Affected file lib/silccore/silcprotocol.c.
3484 * Call silc_protocol_cancel for active protocols in the
3485 silc_server_close_connection if the funtion
3486 silc_server_free_sock_user_data has not been called.
3487 Affected file silcd/server.c.
3489 * Generic tasks cannot be deleted using the del_by_fd
3490 task deleting function since generic tasks does not match
3491 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3493 * Added a notion to SILCOPER help file that the SILCOPER works
3494 only on router server, not on normal server.
3496 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Added for WIN32 support for the new scheduler as well.
3499 Affected file lib/silcutil/win32/silcwin32schedule.c.
3501 * Fixed the SHA1 implementation to work on various platforms.
3503 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3506 API. It is part of the scheduler now. Everything else is
3507 as previously but some functions has changed their names.
3508 Checkout the lib/silcutil/silcschedule.h for the interface.
3509 Updated all applications to use the new interface. Affected
3510 files are lib/silcutil/silcschedule.[ch].
3512 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Found a bug in the SKE implementation. The HASH value,
3515 specified by the protocol, was not computed correctly. The
3516 public key of the responder was not added to the computation
3517 even though it is mandatory. Affected file lib/silcske/silcske.c.
3518 This unfortunately causes incompatibilities with older
3519 clients and servers.
3521 * Added WIN32 specific network init and uninit functions:
3522 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3523 the Winsock2. Affected file lib/silcutil/silcnet.h and
3524 lib/silcutil/win32/silcwin32net.c.
3526 * Set the socket always to nonblocking mode on WIN32 after
3527 reading data or writing data. Affected file is
3528 lib/silcutil/win32/silcwin32sockconn.c.
3530 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Fixed various compilation problems under WIN32. Affected
3533 files lib/silcutil/win32/silcwin32thread.c and
3534 lib/silcutil/win32/silcwin32schedule.c.
3536 * Removed all _internal.h #includes from public header
3537 files. Internal headers must never be included from
3540 Removed also the lib/silcske/payload_internal.h file.
3542 * All include files that may be needed (public and some others
3543 included by the public headers) by application developers are
3544 now copied to the ./includes directory. It does not copy any
3545 internal headers. Affected file Makefile.defines.pre and all
3546 Makefile.am's under lib/ and subdirs.
3548 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Do not change the ~/.silc directory's permissions automatically.
3551 Affected file irssi/src/silc/core/clientutil.c.
3553 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Do not cancel the protocol in silc_server_close_connection
3556 it might cause recursion. Now cancelled in the function
3557 silc_server_free_sock_user_data. Affected file silcd/server.c.
3559 * Fixed the silc_server_remove_clients_by_server to regenerate
3560 the channel keys correctly finally. Added also new function
3561 silc_server_remove_clients_channels to actually do it.
3562 Affected file silcd/server.c.
3564 * Fixed the silc_server_new_channel to not crash by giving
3565 wrong router to the new channel. Affected file is
3566 silcd/packet_receive.c.
3568 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3571 which is given as argument to the silc_client_alloc now.
3572 It can be used to configure the client and set various parameters
3573 that affect the function of the client.
3575 * The USERS command in server did not check whether the channel
3576 is private or secret. Affected file silcd/command.c.
3578 * Added new argument to the USERS command in protocol specification.
3579 The USERS command now can take the channel name as argument
3580 as well. Added support for this in client and server and
3581 updated the protocol specs.
3583 * Completed the GETKEY command in client. It can be now used
3584 to fetch also servers public key not only some clients.
3585 Affected files lib/silcclient/command[_reply].c.
3587 * Added silc_client_get_server to return server entry by the
3588 server name. Affected files lib/silcclient/silcapi.h and
3591 * Redefined the IDENTIFY command in protocol specification to be
3592 more generic. It now can be used to query information about
3593 any entity in the SILC Network, including clients, servers and
3594 channels. The query may be based either the entity's name
3595 or the ID. Added support for this in both client and server.
3597 Affected files silcd/command.c and lib/silcclient/command.c
3598 and command_reply.c.
3600 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3601 the _from_client and _from_server functions. Affected file
3604 * Added silc_client_get_channel_by_id_resolve to the file
3605 lib/silcclient/silcapi.h to resolve channel information by
3606 its ID. Added also silc_client_get_channel_by_id that
3607 does not resolve it from the server.
3609 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * Added SilcServerEntry context into the client library
3612 to represent one server. The INFO command now allocates
3613 these to save the resolved server info. For now on the
3614 client library will also keep information about servers,
3615 connected and resolved with INFO.
3617 The INFO command now allocates the SilcServerEntry context
3618 and saves the server info there. The COMMAND_REPLY in
3619 the INFO now returns the parameters to application in
3620 same order as defined in the protocol specification.
3622 The entries are cached in the client->server_cache.
3624 * The INFO command is now issued after received the Client ID
3625 from the server. Affected file lib/silcclient/client.c.
3627 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3628 to the application as the mode changer might be server.
3629 It is guaranteed that NULL is not returned anymore to the
3630 application. Affected file lib/silcclient/client_notify.c.
3632 The ID Type is now also passed to the application so that
3633 it can check whether the returned entry is SilcClientEntry
3636 Added new function silc_client_get_server_by_id to return
3637 the server entry by ID. Affected files are the
3638 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3640 * Do not create the channel in the Irssi SILC Client when issuing
3641 the JOIN command but when received the sucessful JOIN command
3642 reply. Otherwise the channel might get created even though we
3643 could not join it. The Affected file is
3644 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3646 * Fixed a channel joining bug in router. The router must also
3647 check the channel modes, invite and ban lists etc. when serving
3648 the JOIN command sent by normal server. Affected file is
3649 silcd/command.c. The router now resolves the client's
3650 information from the server who sent the JOIN command if it
3651 does not know it, and processes the JOIN command only after
3654 * Changed the SilcCommandCb to take new argument; void *context2.
3655 Affected file lib/silccore/silccommand.h
3657 The second argument in the command callbacks in the server now
3658 includes the SilcServerCommandReplyContext if the command was
3659 called as pending command callback from the command reply.
3660 Otherwise it is NULL. When called as pending the status of the
3661 command reply will be checked and if it was erronous the
3662 error will be sent to the original sender of the command.
3663 This way the client always receives the error messages even
3664 though the server was actually the one who received the error
3665 when it resent the command to router, for example. Affected
3666 files silcd/command[_reply].[ch].
3668 * Fixed sending WHOWAS command's error message to client if
3669 the requested client could not be found. It was missing.
3672 * Changed the CMODE and CUMODE commands reply arguments in the
3673 protocol specification. The Channel ID is now sent in both
3674 of the commands to identify the channel. Implemented this
3675 new feature to the client and server. Affected files
3676 lib/silcclient/command_reply.c and silcd/command.c.
3678 * Made better checks for invite and ban lists in the JOIN
3679 command in server. Affected file silcd/command.c.
3681 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * The server now performs the incoming host IP/DNS lookup
3684 using the silc_socket_host_lookup and thus does not block
3685 the server anymore. Affected file silcd/server.c.
3687 * Completed the multi-thread support for SILC Scheduler in
3688 the lib/silcutil/silcschedule.c.
3690 * Fixed the configure.in.pre to detect the pthread correctly
3693 * Fixed a deadlock in silc_task_queue_wakeup in the file
3694 lib/silcutil/silctask.c.
3696 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3698 * Added new function silc_schedule_wakeup that is used in
3699 multi-threaded environment to wakeup the main thread's
3700 schduler. It needs to be used when a thread adds a new task
3701 or removes a task from task queues. After waking up, the
3702 scheduler will detect the task queue changes. If threads
3703 support is not compiled in this function has no effect.
3704 Implemented the wakeup mechanism to both Unix and WIN32
3705 systems. Affected files are lib/silcutil/silcschedule.[ch],
3706 lib/silcutil/unix/silcunixschedule.c and the
3707 lib/silcutil/win32/silcwin32schedule.c.
3709 * Added new function silc_task_queue_wakeup to wakeup the
3710 scheduler by the specified task queue. Affected file
3711 lib/silcutil/silctask.[ch].
3713 * The silc_socket_host_lookup_start now wakes up the scheduler
3714 after adding the timeout task. Affected file is
3715 lib/silcutil/silcsockconn.c.
3717 * The silc_socket_host_lookup is synchronous now if the threads
3718 support is not compiled in. However, the callback is still
3719 called asyncronously through the scheduler, anyway. Affected
3720 file lib/silcutil/silcsockconn.c.
3722 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3724 * Added new function silc_socket_host_lookup to perform
3725 asynchronous IP and FQDN lookups for the socket connection.
3726 Affected files lib/silcutil/silcsockconn.[ch].
3728 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3731 that may or may not compile the mutex support in.
3733 Changed the silc_mutex_alloc interface. It allocates the
3734 mutex now to the sent pointer and returns TRUE or FALSE.
3736 Affected file lib/silcutil/silcmutex.h.
3738 * Wrote the SILC Task Queue interface to support multi-threads.
3739 Affected file lib/silcutil/silctask.[ch].
3741 * Wrote the SILC Scheduler to support multi-threads. Affected
3742 file lib/silcutil/silcschedule.c.
3744 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3747 in lib/silcutil/win32/.
3749 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3751 * Defined SILC Mutex API and SILC Thread API and implemented
3752 them for Unix. Affected files are
3753 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3754 lib/silcutil/unix/silcunixmutex.c and
3755 lib/silcutil/unix/silcunixthread.c.
3757 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Fixed the silc_server_remove_clients_by_server's channel
3760 key re-generation. The hash table handling was incorrect
3761 and would not work with many channels. Affected file is
3764 * Fixed some memory leaks around the server code.
3766 * Rewrote the silc_server_get_users_on_channel to support IPv6
3767 based Client ID's. Affected file silcd/server.c.
3769 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3770 specification. However, a separate document must be written
3771 to define the detailed signing procedure and the payload
3772 associated with the flag. Defined the flag to the
3773 lib/silccore/silcchannel.h as well.
3775 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Changed the dynamic tables to static size tables in the
3778 lib/silccrypt/silchmac.c.
3780 * Removed GCC dependencies from the code. A patch by cras.
3782 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3784 * Do not show the error "Error receiving packet bla bla"
3785 in server if it really was not an error (-2 means that reading
3786 is pending). Affected file silcd/server.c.
3788 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3790 * Fixed a possible crash in silc_server_remove_clients_by_server
3791 in silcd/server.c. Fixed there also some memory leaks.
3793 * Fixed the silc_idlist_replace_client_id. It could replace
3794 wrong key in the hash table. Affected file silcd/idlist.c.
3796 * Do not check whether there are global users on the channel
3797 if the channel->global_users is FALSE. Affected functions
3798 silc_server_remove_from_one_channel and
3799 silc_server_remove_from_channels in silcd/server.c. Also,
3800 do not check if the removed client is local as we can be
3801 sure that global client was not removed from the channel
3802 and checking for global users is not needed.
3804 * The silc_server_remove_clients_by_server now re-generates
3805 the channel keys correctly for those channels that had
3806 clients removed from them. Affected file silcd/server.c.
3808 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Found the reason of random crashes in the server. We weren't
3811 ignoring the SIGPIPE signal (which can be sent in write())
3812 and it crashed the server. Affected file silcd/silcd.c.
3814 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3816 * Assure that sock->user_data is not NULL in the function
3817 silc_server_packet_send in silcd/packet_send.c.
3819 * Disconnect the remote connection if it could not be added
3820 to any ID lists in the server. The affected file is
3823 * Check in silc_server_packet_send[_real/dest] that the
3824 socket is not disconnecting and ignore the data if it is.
3825 Affected file silcd/packet_send.c.
3827 * Define inline to __inline on native WIN32 compilation.
3828 Affected file includes/silcwin32.h.
3830 * Added some explicit type casts for inline code since MSVC
3831 require them. Affected files lib/silcutil/silcbuffer.h,
3832 lib/trq/silcdlist.h and lib/trq/silclist.h.
3834 * Print warning in log files from now on if the packet
3835 decryption fails. Affected file silcd/server.c.
3837 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * Changed the `say' client operation's interface to accept
3840 new `type' argument to indicate the type of the message sent
3841 by the library. The application may filter the library's
3842 messages according the type. The affected file is the
3843 lib/silcclient/silcapi.h.
3845 * Added two new functions to lib/silcclient/silcapi.h:
3846 silc_client_del_client and silc_client_del_client_by_id.
3847 Affected file lib/silcclient/idlist.c.
3849 * Moved the clientincludes.h from includes/ to silc/ and
3850 serverincludes.h from includes/ to silcd/.
3852 * The modes for the CMODE and CUMODE are now passed as
3853 uint32 for application with COMMAND_REPLY. The affected
3854 file is lib/silcclient/command_reply.c.
3856 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3858 * /WHOIS without arguments shows client's own information.
3859 Affected file lib/silcclient/command.c.
3861 * Changed PING to not accept any arguments. The specs
3862 says that client can ping only the connected server so
3863 requiring an argument is not needed. Affected file is
3864 lib/silcclient/command.c.
3866 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Fixed a fatal bug in private message sending and reception
3869 encryption and decryption when using private message keys.
3870 The implementation was incorrect and did not follow the
3871 specification. It causd that some of the message were
3872 lost since it did not use the sending and receiving keys
3873 as the protocol suggests. This has been fixed and will cause
3874 incompatibilities with older clients when sending private
3875 message encrypted with private message keys. Affected files
3876 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3877 and various other in Irssi SILC Client.
3879 Added `responder' boolean argument to the functions
3880 silc_client_add_private_message_key[_ske] to indicate when
3881 the key is added as responder or initiator of the key
3884 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3886 * Removed the silc_ske_check_version function and created
3887 a SilcSKECheckVersion callback. Added also a function
3888 silc_ske_set_callbacks that is now used to set all SKE
3889 callbacks. The callback functions are not given to
3890 the SKE functions anymore, but this function is used to
3893 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3895 * Added `silc_version' argument to the silc_client_alloc
3896 to define the version of the application for the library.
3897 The library will use the version string to compare it
3898 against the remote host's (usually a server) version
3899 string. Affected file lib/silcclient/silcapi.h
3901 * Added the KE protocol context to Key Agreement context
3902 in client library so that we can abort the SKE if it
3903 is in process when we get timeout. Affected file is
3904 lib/silcclient/client_keyagr.c.
3906 * Do not resolve the client ID forever if it returns in the
3907 first time that such client does not exist. This was done
3908 for example with private message. Affected file is
3909 lib/silcclient/client_prvmsg.c.
3911 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Do not add regex.h for WIN32. The affected file
3914 includes/silcincludes.h.
3916 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3917 not work yet 100%. It generates the DLL's automatically
3918 when compiling with --with-win32 under cygwin.
3920 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * lib/contrib/regex.c is not compiled on WIN32.
3924 * Added silc_net_get_socket_opt function to the
3925 lib/silcutil/silcnet.h.
3927 * Added includes/silcwin32.h for WIN32 specific includes
3930 * Do not use ptime structure or any of the posix process
3931 functions on WIN32 in lib/silccrypt/silrng.c.
3933 * Added silc_gettimeofday to provide generic function
3934 for struct timeval on all platforms. Added the function
3935 to lib/silcutil/silcutil.h.
3937 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3939 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3940 library as they clearly belong there. As a plus side we
3941 can make the actual socket connection routines platform
3944 Added also new generic function silc_socket_read and
3945 silc_socket_write (that used to be silc_packet_[read/write].
3946 The implementation of these are platform specific.
3948 * Added WIN32 specific routines of silc_socket_[read/write]
3949 to lib/silcutil/win32/silcwin32sockconn.c.
3951 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Added preliminary support for native WIN32 compilation under
3954 cygwin (using the -mno-cygwin option for GCC) to the
3955 ./configure.in.pre. The --with-win32 now prepares the
3956 compilation for native WIN32.
3958 * Rewrote the SILC Scheduler interface in the file
3959 lib/silcutil/silcschedule.h. The scheduler is now context
3960 based and does not have anymore any global static scheduler.
3961 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3962 and created lib/silcutil/win32 directory for WIN32 based
3965 * Added Unix specific network routines to the
3966 lib/silcutil/unix/silcunixnet.c and the old
3967 lib/silcutil/silcnet.c includes now only generic routines.
3969 Added WIN32 specific network routines to the
3970 lib/silcutil/win32/silcwin32net.c.
3972 * Added Unix specific utility functions from the
3973 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3975 * Added WIN32 SILC Scheduler to the file
3976 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3979 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3981 * Do not handle JOIN notify in the server if the target client
3982 is not registered (idata->registered == FALSE). The affected
3983 file is silcd/packet_receive.c.
3985 * Update the nickrec->founder in event_cumode in the Irssi SILC
3986 client. Affected file irssi/src/silc/core/silc-channels.c.
3988 * Fixed the CUMODE_CHANGE notify handling in the server when
3989 server and router are announcing their clients on channels.
3990 Now the mode changes are saved and notified correctly. The
3991 affected file is /silcd/packet_receive.c.
3993 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3994 They really did not replace the cache entry in the ID Cache.
3995 Now they do that. Affected file silcd/idlist.c.
3997 * Fixed the KICK notify handling in the Irssi SILC client to
3998 update the channel records so that the kicked client does not
3999 appear to be on the channel. The affected file is
4000 irssi/src/silc/core/silc-channels.c.
4002 * Always update the conn->current_channel when executing command
4003 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4005 * Fixed the KILL notify handling in Irssi SILC client to remove
4006 the killed client on all channels.
4008 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Fixed the silc_parse_command_line to remove extra spaces
4011 from the start and end of the arguments. Affected file is
4012 lib/silcutil/silcutil.c.
4014 * Cancel and free any active protocol in the function
4015 silc_server_close_connection. Affected file silcd/server.c.
4017 * Cancel and free any active protocol in the function
4018 silc_client_close_connction. Affected file is
4019 lib/silcclient/client.c.
4021 * Do not execute the KILL command for clients that are in
4022 history (ie. they are not in the network). Affected file is
4025 * Fixed KILL notify handling, client does not crash anymore.
4026 Affected file irssi/src/silc/core/silc-channels.c.
4028 * Reduced the default packet buffer size from 2048 to 1024 in
4029 lib/silccore/silcpacket.c.
4031 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4032 counter to the SKE context that is incresed when the SKE library
4033 performs async operation outside the library. If the outside
4034 process frees the SKE context and FREED status will be set
4035 and the library will detect after the sync operation that the
4036 libary is freed. The affected files are
4037 lib/silcske/silcske[_status].[ch].
4039 * Resolve the client entry information in the function
4040 silc_client_channel_message to assure that NULL pointer is not
4041 passed as client entry to the application. */
4043 * Fixed the task timeout calculation to assure that there is
4044 never negative timeouts. The affected file is
4045 lib/silcutil/silcschedule.c.
4047 * Fixed the channel user mode notification sending in server.
4048 It was sent point-to-point to the router (or to server by router)
4049 but it needs to be destined to a channel. The routines now
4050 supports sending the channel user mode notifys to the channels
4051 when announcing clients and channels. Affected files are
4052 silcd/server.c and silcd/packet_receive.c.
4054 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4055 It did not actually replace the old channel entry in the cache.
4056 Affected file lib/silcclient/client_notify.c.
4058 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Fixed a possible crash in silc_packet_send_prepare. It now
4061 assures always that there is enough space in the buffer and
4062 at the tail area of the buffer (for MAC).
4064 Fixed the inbound buffer reallocation in silc_packet_read.
4065 It was old code and did not handle the reallocation correctly.
4068 The affected file is lib/silccore/silcpacket.c.
4070 * Fixed buffer overflow in silc_parse_nickname in the file
4071 lib/silcutil/silcutil.c.
4073 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * make install generates new server keys only if there is not
4078 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4081 Added check that if the NOREPLY is set then we will not send
4082 the away message. This avoids infinite loop of away messages
4083 if both clients are away. The affected file is
4084 lib/silcclient/client_prvmsg.c.
4086 * Fixed client crash if /NICK was given without arguments.
4087 Affected file lib/silcclient/command.c.
4089 * Server does not send the invite list in INVITE command back
4090 to the client if the list was not altered. Added this notion
4091 to the protocol spec as well. Affected file silcd/command.c.
4093 Fixed possible crash in INVITE command by checking the
4094 value of silc_server_get_client_route command.
4096 * Fixed the INVITE notify type handling. The arguments are now
4097 taken in correct order and client does not crash. The affected
4098 file is irssi/src/silc/core/silc-channels.c.
4100 Removed the "Inviting xxx to channel" message from the
4101 client library away and let the application handle it.
4102 Affected file lib/silcclient/command.c. Added that message
4103 to Irssi SILC client's message formats.
4105 * Fixed CMODE command crash in client. It now checks the
4106 amount of arguments correctly and does not crash. The affected
4107 file is lib/silcclient/command.c.
4109 * Do not create new channel automatically in silc_channels_join
4110 but check whether the channel by that name already exists.
4111 Affected file irssi/silc/core/silc-channels.c.
4113 * Do not send the SERVER_SIGNOFF to router if the disconnected
4114 entity was the router. Affected file silcd/server.c.
4116 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4117 SILC client as it was missing from there.
4119 Added the handling of the KICK notify to the Irssi SILC client
4120 as it was missing. Added "you have been kicked" message to
4121 Irssi SILC client's message modules formats.
4123 Added the handing of the KILL notify to the Irssi SILC client
4124 as it was missing. Added the kill message module formats
4127 The affected file is irssi/src/silc/core/silc-channels.c.
4129 * The router did not save the channel mode the server announced.
4130 Affected file silcd/packet_receive.c.
4132 * Fixed a possible crash in INFO command in server. If the
4133 server did not provide the server info it crashed. Affected
4134 file silcd/command.c.
4136 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Fixed the GETKEY command in the server to check also the
4139 global list. Otherwise the GETKEY would not work correctly
4140 in normal SILC server. Affected file silcd/command.c.
4142 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Fixed GETKEY crash, it crashed if the command did not succseed.
4146 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4149 is now real and not just an macro interface to GMP.
4151 Removed the entire GMP from the source tree and imported new
4152 NSS MPI library instead. Reason for removing GMP is that it is
4153 extremely large and compiles extremely slow. The NSS MPI
4154 is only a few files and compiles in less than 10 seconds.
4155 The speed is also about the same as GMP. The MPI is imported
4156 to lib/silcmath/mpi.
4158 If the system has GMP installed we will still use the GMP.
4159 If it is not then the NSS MPI will be compiled.
4161 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Merged a long nickname (127 characters long) crash bugfix from
4164 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4166 * Merged a freed memory reference bugfix from Irssi CVS tree.
4167 Affected file irssi/src/core/commands.c.
4169 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Added the server's public key sving and verification to the
4172 server when performing the SKE. This was missing and the
4173 remote server's (or router's) public key was accepted without
4174 checking whether we have it previously or trust it at all.
4175 Affected file silcd/protocol.c.
4177 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Check in the silc_server_timeout_remote if protocol is active
4180 and make sure that the protocol's final callback is called so
4181 that all memory if freed. Affected file silcd/server.c.
4183 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * silc_server_whois_send_reply crashed the server if the nickname
4186 was 127 characters long. Affected file silcd/command.c.
4188 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Added sanity check to the silc_server_new_client. If the hostname
4191 is provided inside username then check that the provided hostname
4192 really is the same as the resolved one. If the hostname was not
4193 resolved then check it from the public key. Affected file is
4194 silcd/packet_receive.c.
4196 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4197 if the server disconnected us and the connection is not valid
4198 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4200 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4201 the library to the lib/silcutil/silcutil.[ch].
4203 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Close log file after open. Affected file
4206 lib/silcutil/silclog.c.
4208 * Check whether sock == NULL in silc_client_send_packet and return
4209 if it is. Affected file lib/silcclient/silcclient.c.
4211 * Check rec->entry == NULL in the Irssi SILC Client before
4212 sending the channel message. Affecte file is
4213 irssi/src/silc/core/silc-servers.c.
4215 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Merged a splitted window bugfix from Irssi CVS tree. The
4218 affected file is irssi/src/fe-text/textbuffer-view.c.
4220 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4221 It did not print nickname.
4223 * Improved the distributions system a bit.
4225 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4228 irssi/src/fe-text/gui-window.c.
4230 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4231 to in-active server. The affected file is
4232 irssi/src/silc/core/client_ops.c.
4234 * Resolve the client in USERS command reply if the entry does
4235 not have username resolved. The affected file is
4236 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4237 command to WHOIS command to really resolve stuff. The USERS
4238 is not used any more in any critical section so WHOIS can
4239 be used even though it might be slower than IDENTIFY.
4241 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4244 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Changed the protocol API a bit more consistent in the
4247 lib/silccore/silcprotocol.[ch].
4249 * Changed the following headers to ROBODoc format:
4251 lib/silccore/silcpayload.h
4252 lib/silccore/silcprotocol.h
4253 lib/silccore/silcsockconn.h
4255 All core library headers are now formatted.
4257 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Fixed a bug in Irssi SILC client; do not show that you are
4260 server/router operator if you really are not. Affected file is
4261 irssi/src/silc/core/client_ops.c.
4263 * Renamed silc_command_free_payload to silc_command_payload_free.
4264 Affected file lib/silccore/silccommand.h
4266 * Added silcmath.h to include the prototoypes of various routines
4267 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4270 * Changed the following headers to ROBODoc format:
4272 lib/silccore/silcchannel.h
4273 lib/silccore/silccommand.h
4274 lib/silccore/silcid.h
4275 lib/silccore/silcidcache.h
4276 lib/silccore/silcmode.h
4277 lib/silccore/silcnotify.h
4278 lib/silccore/silcpacket.h
4279 lib/silcmath/silcmath.h
4281 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Added checking to the server code not to start the server if
4284 ciphers and stuff are not configured properly. Affected files
4285 silcd/serverconfig.[h] and silcd/server.c.
4287 * Changed the layout of the header files of the public interfaces
4288 in the SILC libraries. The new layout supports ROBODoc
4289 documentation tool (and some others) so that it is easy to create
4290 a library reference manual. All the other headers and source
4291 code must still follow the CodingStyle document. Also source
4292 code must not include these ROBODoc stuffs, only the headers.
4293 Furthermore, all public interface headers must now be named
4294 by using `silc' prefix, example: silcapi.h, silccipher.h.
4295 Some files were renamed due to this. All the other headers
4296 must not be used as public interfaces. I will update the
4297 CodingStyle document later. Changed following headers, so far:
4299 lib/silcclient/silcapi.h
4300 lib/silccore/silcauth.h
4301 lib/silccore/silcprivate.h
4302 lib/silccrypt/silcdh.h
4304 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Removed silc_client_packet_send_flush from the client library
4309 as it is not needed. Affected file lib/silcclient/client.[ch].
4311 * Added printing of message of unresolved authentication method
4312 to the Irssi SILC client. Added it to the module formats.
4313 Removed the same message from the client library.
4315 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Added new distribution feature, DISTLABEL. Every distribution
4318 can define own preprocessor label that can be used in the
4319 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4320 file distributions, acconfig.h.pre and prepare.
4322 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Added Makefile.defines_int to include the actual definitions
4325 for Makefile.defines.in. Tested the new distribution system,
4326 created distributions and tested installation.
4328 * Added AWAY message printing to the Irssi SILC client. Added
4329 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4331 * Added SCONNECT command to call the SILC's CONNECT command.
4332 Cannot use CONNECT directly since Irssi uses that internally.
4333 Affected file irssi/src/silc/core/silc-servers.c.
4335 Added ACTION local command. It is same as ME command but takes
4336 the channel as mandatory argument.
4338 Rewrote some of the Irssi's help files to suite for SILC
4341 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Added Makefile.defines[.in] that should for now on be included
4344 in all Makefile.am file in the source tree. That file includes
4345 all common compilation definitions for SILC source tree.
4347 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Minor changes to the ./prepare script to change the package
4350 name according the distribution name to the configure.in.
4352 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Created new distribution system. Added file `distributions'
4355 that defines all the distributions that can be created out of
4356 the SILC source tree. The ./prepare script now reads that
4357 file to determine how to prepare the distributions. The
4358 first argument to the ./prepare is the name of the distribution
4359 and second is the version of the distribution. If given
4360 without arguments it creates the default (toolkit) distribution
4361 with the default version (defined in ./prepare).
4363 All Makefile.am files that are subject to the distributions
4364 are now named as Makefile.am.pre. These are ./Makefile.am
4365 and lib/Makefile.am. Others may be changed later.
4367 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Added invite list, ban list, some key management and connection
4370 error message printing to module formats in the Irssi SILC client.
4372 * Added new silc_client_set_away_message to set the away message
4373 that is back to the person who sent private message. The
4374 affected file lib/silcclient/silcapi.h and the
4375 lib/silcclient/client_prvmsg.c.
4377 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Fixed the private message sending in the Irssi SILC client,
4380 added local command KEY to the Irssi SILC client.
4382 Added key management and key agreement message formats to the
4383 irssi/src/fe-common/silc/module-formats.[ch].
4385 Added USERS (alias WHO) printing, server/router operator
4386 indication and LIST command printing to the module formats.
4388 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Fixed channel joining notify handling, cumode notify handling
4391 from Irssi SILC client.
4393 * Added SILC specific module-formats to the Irssi SILC client so
4394 that SILC specific message hilighting, colors etc is possible.
4395 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4397 Added channel mode, channel user mode, actions, notices,
4398 whois and whowas printing to the the module-formats.c.
4400 * Fixed a bug in channel deletion in the server. The channel
4401 is not left to the cache even if the channel founder auth mode
4402 is set when there are no users anymore on the channel. Affected
4403 file silcd/server.c.
4405 * The silc_net_localhost now resolves the entire hostname including
4406 the domain name. Affected file lib/silcutil/silcnet.c.
4408 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Changed the ask_passphrase client operation to be ascynchronous.
4411 It has now a completion callback and a context that the
4412 application must call after it has got the passphrase from
4413 the user. Affected files lib/silcclient/silcapi.h,
4414 lib/silcclient/protocol.c, lib/silcclient/command.c and
4417 Added SilcAskPassphrase callback that the application calls
4418 to deliver the passphrase to the library.
4420 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4421 The public key verification and especially a certificate
4422 verification is asynchronous procedure.
4424 Added new SILC_SKE_STATUS_PENDING status to indicate the
4425 request is pending and a callback will be called to finalize
4428 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4429 indicate that remote end did not send its public key (or
4430 certificate), even though we require it. Added check for this
4431 condition in the SKE. This was a security bug, now fixed.
4433 Defined new SilcSKEVerifyCbCompletion callback that is called
4434 when the verification process is completed.
4436 The affected files lib/silcske/silcske_status.h and
4437 lib/silcske/silcske.[ch].
4439 * Changed the verify_public_key client operation to be async
4440 as well. Defined SilcVerifyPublicKey callback that is used to
4441 indicate the success of the public key verification process.
4443 Changed the server and client to use the new async client
4446 * Changed the Irssi SILC client's internal scheduler to be called
4447 twice as many times as it used to be. As a result the client
4448 should be a bit faster now. Affected file is
4449 irssi/src/silc/core/silc-core.c.
4451 * Added support to Irssi SILC client of asynchronous public key
4452 verification and passphrase inquiry. Affected file is
4453 irssi/src/silc/core/silc-core.c.
4455 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Do not say "You have left channel %s" in client library.
4458 Moved it to the application. Affected files are
4459 lib/silcclient/command.c and silc/client_ops.c.
4461 * Fixed silc_client_get_clients. Command context was not
4462 duplicated and was freed memory in the callback. Affected
4463 file lib/silcclient/idlist.c.
4465 * Do not say "you are now talking..." on JOIN command in the
4466 client library. The appliation must handle it.
4468 * Do not say ".. changed topic to" in command reply in the
4469 client libary. The application must handle it.
4471 * Fixed TOPIC command sending in the client library.
4473 * Fixed a memory leak in silc_client_command_free in the file
4474 lib/silcclient/command.c.
4476 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Imported a modified version of Irssi client to the source tree.
4479 The Irssi will be used to create a new client called
4480 Irssi SILC. Imported to irssi/.
4482 Added silc_core_init_finish function to the Irssi. Affected
4483 file irssi/configure.in.
4485 A lot changes in the Makefile.ams around the irssi tree.
4487 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Do not rehash if the new size is same as the old size of the
4490 hash table, in the silc_hash_table_rehash*. The affected file
4491 lib/silcutil/silchashtable.c.
4493 * Replaced hash_table_del_by_context calls from the server
4494 (when channel->user_list and client->channels) to the
4495 hash_table_del as it is sufficient and faster.
4497 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Added silc_hash_table_list, silc_hash_table_get and the
4500 SilcHashTableList structure to provide an alternative way to
4501 traverse the hash table. The affected files are
4502 lib/silcutil/silchashtable.[ch].
4504 * Changed the server's idlist routines to use the hash table
4505 routines to optimize the code.
4507 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Replaced the client entry's `channel' list and channel entry's
4510 `user_list' list to hash tables for optimized lookup. Changed
4511 the code to use the hash table interface around the code.
4512 Affected file lib/silcd/idlist.[ch].
4514 * Added `auto_rehash' boolean argument to the function
4515 silc_hash_table_alloc to indicate whether the hash table should
4516 auto-rehash when it thinks is appropriate time. It will
4517 increase the hash table size if the there is twice as much
4518 entries in the table than the size of the table, and will
4519 decrease the size if there are twice as less entries than
4520 the size of the table.
4522 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4526 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * silc_idcache_purge_by_context deletes the entry now by context
4529 as it is supposed to do. Affected file lib/silccore/idcache.c.
4531 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4532 client is not anymore valid (WHOWAS givens the info) and not
4533 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4535 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Removed the `data' and `data_len' arguments from the ID Cache
4538 interfaces and added `name' argument. ID Cache does not handle
4539 anymore the binary data only a names associated with given ID.
4541 * When hashing a Client ID with silc_hash_id the entire ID is
4542 not hashed anymore, instead only the hash of the Client ID is
4543 hashed. This way we can access the Client ID from the cache
4544 with Client ID but with the hash of the ID (which is a hash of
4545 the nickname) as well without any difference in performance.
4547 Added also silc_idcache_find_by_id_one_ext to do one on one
4548 searching when we have the actual ID. Added also function
4549 silc_hash_client_id_compare. The affected files are
4550 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4552 * When hashing the name associated with a ID it is always done
4553 in lowercase. This way we can access the cache without worrying
4554 about case-sensitivity, even though, for example nicknames are
4557 * Fixed a bug in server with channel message sending. It put
4558 wrong ID type as destination ID. The affected file
4559 silcd/packet_send.c.
4561 * silc_idcache_del_by_context now deletes from all hash tables
4562 by context. Affected file lib/silccore/idcache.c.
4564 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Changed the client library to use the new ID Cache interface.
4567 Changes around the source tree.
4569 * Added silc_hash_table_rehash_ext to rehash with specific
4570 hash function. Affected file lib/silcutil/silchashtable.[ch].
4572 * Added silc_hash_string_compare to compare two strings in the
4573 hash table. Affected file lib/silcutil/silcutil.[ch].
4575 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Added new function silc_idcache_del_by_context into the
4578 lib/silccore/idcache.[ch].
4580 * Changed the server's ID list routines to use the new ID Cache
4581 interface. Changes around the source tree.
4583 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added silc_hash_table_del[_by_context]_ext functions in to the
4586 lib/silcutil/silchashtable.[ch].
4588 Removed silc_hash_table_find_all* routines and added new
4589 silc_hash_table_find_foreach to replace them.
4591 Added silc_hash_table_replace_ext function as extended
4592 replacing function. Separated the simple hash table interface
4593 from the extended hash table interface in the file
4594 lib/silcutil/silchashtable.h.
4596 * Fixed minor bugs and changed it to use some of the new
4597 hash table functions in lib/silccore/idcache.c
4599 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Added new function silc_hash_table_find_all to return all keys
4602 in the hash table by the specified key. As the hash table is
4603 collision resistant it also makes it possible to have several
4604 duplicate keys in the hash table. This function may be used to
4605 find all of the keys from the hash.
4607 Added user_context arguments to the SilcHashFunction,
4608 SilcHashCompare and SilcHashDestructor to deliver user specified
4611 Added new fuctions silc_hash_table_find[_all]_ext to do
4612 extended lookup with specified hash and compare functions and
4613 specified user contexts.
4615 Added new function silc_hash_table_add_ext to add the key
4616 with specified hash function and user context.
4618 Added new function silc_hash_table_foreach to traverse all
4619 entrys in the hash table. Added SilcHashForeach callback
4622 Added new function silc_hash_table_del_by_context to delete
4623 the entry only if the context associated with the key matches.
4625 Affected files are lib/silcutil/silchashtable.[ch].
4627 * Removed silc_hash_[server/client/channel]_id and added just
4628 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4629 silc_hash_id_compare to compare two ID's using as the hash table
4630 comparison function. Added also silc_hash_data to hash
4631 binary data and silc_hash_data_compare to compare it.
4633 * Removed silc_idlist_find_client_by_hash as it is not needed
4634 anymore. Affected file silcd/idlist.[ch].
4636 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4637 to use internally the SilcHashTable. The new ID Cache is a lot
4638 faster than the old one. Some of the ID Cache interface was also
4639 rewritten and obsolete and stupid functions were removed.
4641 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Added entry_count field to the SilcHashTable to keep the number
4644 of the entries in the table. Implemented the function
4645 silc_hash_table_rehash. Added new function
4646 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4648 Fixed a minor bug in silc_hash_table_free.
4650 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4651 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4652 into the lib/silcutil/silcutil.[ch].
4654 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Implemented a collision resistant hash table into the
4657 lib/silcutil/silchashtable[ch]. See the header and the source
4658 for the SilcHashTable API.
4660 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Merged dotconf version 1.0.2 into lib/dotconf.
4664 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Do not compile anything in lib/silcsim/* if the SIM support
4667 is not enabled. The tree should now compile without problems
4670 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Compiled the SILC under cygwin. Compiled and tested briefly
4673 without problems. More tests needed. The SIMs didn't compile
4676 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4678 * Fixed possible crash in silc_get_username in the
4679 lib/silcutil/silcutil.c.
4681 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Fixed a va_arg in silc/client_ops.c.
4685 * Oops, RC5 routines were named AES and caused some problems
4686 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4688 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Added new SilcIDIP structure into the lib/silccore/id.h and
4691 replaced the old `ip' fields from all SILC ID's to that type.
4692 This is a step towards IPv6 support.
4694 The silc_id_get_len takes now the ID as an extra argument.
4695 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4696 both IPv4 and IPv6 based ID's.
4698 The affected files are lib/silccore/id.[ch] and other files
4699 around the tree using these routines.
4701 * Removed the ID length arguments in server from various
4702 silc_server_send_notify_* routines -> they are not needed
4705 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Fixed memory leak in silc_encode_pem_file in the file
4708 lib/silcutil/silcutil.c.
4710 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Check minor version as well in the SKE. Affected files are
4713 silcd/protocol.c and lib/silcclient/protocol.c.
4715 * Added --identifier option to the server so that an identifier
4716 can be when creating the public key for the server. Affected
4717 file is silcd/silcd.c.
4719 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4720 lib/silccrypt/silcpkcs.c.
4722 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Register default ciphers and stuff when using -C option with
4725 the server. Affected file sildc/silcd.c.
4727 * Put back the servers public key filename format, it is better
4728 than the new one. For now, the client keys are saved with the
4729 new filename format. The affected file silc/client_ops.c.
4731 * Implemented the Cipher API for the rest of the ciphers that
4732 did not implement it or implemented it the wrong way.
4734 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Register default ciphers and stuff when using the -S option
4737 in the client. Affected file silc/silc.c. Same also when
4738 creating new key pair with -C option.
4740 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Fixed the silc_verify_public_key client operation function to
4743 save the public keys differently. The fingerprint is now
4744 used as filename and not the hostname. This way also the
4745 client keys are saved uniquely and not with hostnames. The
4746 affected file is silc/client_ops.c.
4748 * Trimmed the silc_hash_fingerprint function to remove extra
4749 whitespaces from the end of the fingerprint. The affected
4750 file is lib/silccrypt/silchash.c.
4754 * Added silc_cipher_register_default function to register all
4755 default ciphers. It can be used when configuration files
4756 does not exist and the application does not want any specific
4757 ciphers in any specific order.
4759 The SilcDList is now used as silc_cipher_list dynamically
4760 allocated cipher list. Removed the static list all together
4761 and now all ciphers must be allocated to the dynamic list.
4762 The silc_cipher_alloc routine was changed to check only the
4765 All silc_cipher_* routines that used to return int returns
4768 The affected files lib/silccrypt/silccrypt.[ch].
4770 * The same thing was done to silc_hash_* as for silc_cipher_*
4771 routines. Affected files lib/silccrypt/silchash.[ch].
4773 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4774 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4775 Added also silc_pkcs_[un]register[_default] functions.
4776 Removed the data_context from the PKCS API.
4778 * Added silc_hmac_register_default function to register default
4779 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4780 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4781 to unregister all hmacs at once.
4783 * Register the default ciphers, hash functions, PKCSs and HMACs
4784 if client's configuration file does not exist. The affected
4787 * The client did not load the hash functions from the SIM
4788 modules at all. Added support for this. Affected file is
4789 silc/clientconfig.c.
4791 * When decoding public key with silc_pkcs_public_key_decode, check
4792 the supported algorithm only if PKCS are registered. Affected
4793 file lib/silccrypt/silcpkcs.c. The same was done with the
4794 silc_pkcs_private_key_decode.
4796 * Fixed the SILC List routines to keep the list always in order.
4797 It used to change the list's order when traversing the list but
4798 not it preserves the order. Affected file lib/trq/silclist.h.
4800 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Added the client library to use the SilcSocketConnection's
4803 reference counter (by silc_socket_dup) to prevent the bug that
4804 the socket object may be freed underneath async operation.
4806 * The name resolv library checking fixes in the configure.in.pre.
4809 * Created new version of the protocol drafts for future
4810 development. The -03 drafts are the ones that will be changed
4811 in the trunk now and the -02 will remain as they are.
4813 * Send list of CUMODE notifys to the router when announcing
4814 the channel users to the router. Affected file silcd/server.c.
4815 If the router receiving channel founder CUMODE for a channel
4816 that already has channel founder it will send CUMODE notify
4817 to the sender to remove the channel founder rights from the
4818 announced client. Affected file silcd/packet_receive.c.
4820 * The CUMODE notify may now use Server ID as well as the entity
4821 who changes the mode. Updated protocool specs.
4823 * Updated INSTALL and README files.
4825 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * New web pages in the http://silc.pspt.fi. The pages was
4832 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Implemented the [DenyConnectin] config section in the server.
4835 Added silc_server_config_denied_conn to check whether incoming
4836 connection is denied. Affected file silcd/serverconfig.[ch].
4838 * Do not check the ports when checking the incoming configuration
4839 data if the port is 0, meaning any. Affected file is
4840 silcd/serverconfig.c.
4842 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Fixed buffer overflow in silc_string_compare in the file
4845 lib/silcutil/silcutil.c.
4847 * Fixed double free in silc_server_command_leave in the file
4850 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Fixed the version checking in the server. Affected file is
4855 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Fixed the configuration data fetching when accepting new
4858 connections in the server. Affected file silcd/server.c.
4860 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Added `sender_entry' argument to the function
4863 silc_server_packet_relay_to_channel so that we can check
4864 whether some destination actually belongs to the same route
4865 the sender belongs (ie, we must not resend the packet to the
4866 sender). Affected file silcd/packet_send.[ch].
4868 * Added `servername' field to the SilcClientEntry in the server
4869 to hold the name of the server where client is from. Affected
4870 file is silcd/idlist.h.
4872 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Moved the channel message encrypting in the router betwen
4875 router connections from silc_server_channel_message to the
4876 silc_server_packet_relay_to_channel since we want to check
4877 whether we have anybody channel before encrypting anything.
4878 Affected files silcd/packet_[receive/send].c.
4880 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Fixed the [AdminConnection] server config section to support
4883 multiple entries. Affected file silcd/serverconfig.c.
4885 * Added support into the server to check the validity of the
4886 incoming connection before executing any KE or authentication
4889 * The connection configuration is now saved to the KE and
4890 connection auth protocol contexts and not fetched anymore in
4891 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4893 * The local hosts listenning address and port is also resolved
4894 now when starting the server. We want to have the socket object
4895 to include the real address and port for the listener. Added
4896 new function silc_net_check_local_by_sock into the files
4897 lib/silcutil/silcnet.[ch].
4899 * Fixed a broadcast bug in server -> do not broadcast if we
4902 * Fixed a routing bug. Do not route broadcast packets ever.
4903 Broadcast packets must be processed always and not routed since
4904 they may be destined to some other host than yourself and thus
4905 would get routed without no good reason. Affected file is
4908 * Added function silc_server_config_is_primary_route to check
4909 whether primary router connection has been configured (a router
4910 configuration that we are initiating). If there is not, we
4911 will assume that there is only two routers in the SILC network
4912 and we will use the incoming router connection as our primary
4913 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4915 * Changed the order of the broadcasting. Broadcast _after_ the
4916 packet has been processed not before. Affected file is
4919 * Fixed a [ClientConnection] parsing bug. The port was never
4920 parsed correctly thus resulting to port 0. Affected file
4921 silcd/serverconfig.c.
4923 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4924 argument and did not set the broadcast packet flag. Affected
4925 file silcd/packet_send.c. Fixed same bug in the function
4926 silc_server_send_notify as well.
4928 * If we receive NEW_ID packet for our own ID in the server, ignore
4931 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Removed the nickname from the Private Message Payload.
4936 Updated the code and the protocol specs.
4938 * Updated protocol specs for submitting to the IETF.
4940 * Tweaked the Random Number Generator a bit. Affected file
4941 lib/silccrypt/silcrng.c. Exported a new function
4942 silc_rng_[global]_add_noise which can be used to add more
4945 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Do not parse packets with different timeout when protocol
4948 is active -> may cause problem with rekey. Affected file
4951 * When server receives signoff notify it must not create
4952 new channel key if the client is on any channels since the
4953 sender of the signoff notify will create it.
4955 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Added printing of error messages during SKE protocol from the
4958 failure packet sent by server during SKE. Affected file
4961 * Removed the client's failure_callback handling with timeout
4962 and handle it immediately when received.
4964 * The SKE library returned wrong type in SUCCESS and FAILURE
4965 packets. They must be 32 bit MSB not 16 bit MSB.
4967 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Ok, rewrote the logic of the re-key and now it seems to work.
4970 I tested it on high traffic with frequent re-keys without
4971 problems. Added hmac_receive (and renamed hmac to hmac_send)
4972 in SilcClientConnection in lib/silcclient/client.h and
4973 in SilcIDListData in silcd/idlist.h. Also, removed the
4974 SilcPacketParserContext's cipher and hmac fields as they are
4975 not needed anymore and actually caused some problems when
4976 the ciphers and hmac's changed underneath the packet parser.
4978 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * If re-key protocol is active then process the incoming packets
4981 synchronously since we must assure that icoming packets encrypted
4982 with the old key is processed before the new keys is set to
4983 use. This is true other packets than for REKEY packets.
4984 Affected file silcd/server.c. The same was done to client library
4985 as well, affected file lib/silcclient/client.c.
4987 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Fixed bug in client and server to accept the force send if
4990 the packet is send from silc_[server/client]_packet_process
4991 function. Otherwise the packets are never delivered, oops.
4993 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Disable force sending of packets when REKEY protocol is active.
4996 We must assure that no packet is sent directly when rekey is
4997 performed. All packets must be sent through packet queue.
4998 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4999 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5000 function is silc_[server/client]_packet_send_real to check
5003 * Replaced the SIM paths from example config files to
5004 /usr/local/modules. Also, make install creates now
5005 /usr/local/silc/logs directory to hold all the SILC server
5008 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Made the configure.in.pre work on Solaris. Patch by salo.
5012 * Made all ciphers compatible with non-x86 machines. Defined
5013 CBC mode macros into lib/silccrypt/ciphers_def.h.
5015 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Fixed the make install.
5019 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * When MAC computation fails the silc_packet_decrypt returned 0
5022 even though it was supposed to return -1. Fixed this. The
5023 affected file is lib/silccore/silcpacket.c.
5025 * Do not replace the config files in /etc/silc (in make install)
5026 if they already exist. Affected file ./Makefile.am.
5028 * Do not send re-key packets immediately but through packet queue.
5029 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5031 * Changed silc_net_check_host_by_sock to return FALSE if the
5032 IP/DNS could not be resolved. Though, it returns the IP address
5033 now even if it could not resolve it (but returns also FALSE).
5034 Affected file lib/silcutil/silcnet.[ch].
5036 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added silc_pkcs_decode_identifier to decode the public key's
5039 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5040 Added also silc_pkcs_free_identifier. Added also new context
5041 SilcPublicKeyIdentifier.
5043 * Added -S option to the silc client. It is used to dump the
5044 contents of the specified public key file.
5046 * Changed the PKCS api to return the public key length when
5047 setting the public key.
5049 * Fixed a fatal bug in the public and private key file loading.
5050 Affected file lib/silccrypt/silcpkcs.c.
5052 * Execute the packet parsing for client with zero (0) timeout
5053 if the protocol is active. Affected file silcd/server.c.
5055 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Made the key generation options to the silcd program. Added
5058 -C option, equivalent to client's option.
5060 * Added new [ServerKeys] config section to the server. It
5061 configures the server's public and private key.
5063 * Defined generic Public Key Payload into the protocol
5064 specification to send specific type of public keys and
5067 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5068 public key or certificate.
5070 * Implemented the GETKEY command to the server and to the
5071 client library and on user interface.
5073 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Made preliminary `make install' work.
5077 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Added SilcServerRekey context into silcd/idlist.h.
5081 * Added the PFS support as defined in the specification to the
5082 SKE protocol. Affected files lib/silcske/*.c.
5084 * Added `ske_group' field to the SilcServerRekey context to hold
5085 the number of the SKE group that is used with PFS in re-key.
5086 Affected file silcd/idlist.h.
5088 * Added PFS re-key support to the server. Affected file is
5091 * Added silc_protocol_cancel to cancel execution of the next
5092 state of the protocol. Affected file is
5093 lib/silccore/silcprotocol.[ch].
5095 * Added the re-key support with and without PFS to the client
5096 library. Re-key is performed once in an hour, by default.
5098 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5099 Added silc_client_rekey_callback and silc_client_rekey_final.
5100 Affected files are lib/silcclient/protocol.[ch] and
5101 lib/silcclient/client.[ch].
5103 * Removed the `hmac_key' and `hmac_key_len' fields from the
5104 SilcClientConnection structure; not needed. Affected file is
5105 lib/silcclient/client.h.
5109 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Do not ask whether user wants to use the negotiated private key
5112 for private messages, just use it. Affected file is
5113 silc/local_command.c.
5115 * Added `send_enc_key' and `enc_key_len' fields to the
5116 SilcIDListData structure since they are needed in the re-key
5117 phase. Affected file is silcd/idlist.[ch].
5119 * Implemented the simple re-key protocol into the server.
5120 Affected files silcd/server.c and silcd/protocol.[ch]. The
5121 re-key will be performed once in an hour, by default.
5123 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5124 Added silc_server_rekey, silc_server_rekey_callback and
5125 silc_server_rekey_final.
5127 * Removed Tunneled flag from the protocol. Updated the code
5128 and the specifications.
5130 * Adde `pfs' field to the SilcIDListData to indicate whether
5131 the PFS is to be performed in the re-key. Affected file is
5134 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5137 int64 of at least the xintXX size. If void * is less that 4
5138 bytes uint32 * will be used. Defined bool as boolean.
5140 * Changed _ALL_ unsigned long and unsigned int to uint32,
5141 unsgined short to uint16 in the source tree.
5143 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5144 not handle clients that has entry->data.registered == FALSE.
5145 They are not in the network anymore. Affected file is
5148 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Implemented the sending of the SERVER_SIGNOFF notify in the
5151 server. Affected file is silcd/server.c.
5153 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5154 Added also silc_notify_payload_encode_args into the
5155 lib/silccore/silcnotify.[ch].
5157 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5158 Affected file silcd/packet_receive.c.
5160 * Implemented the SERVER_SIGNOFF notify handling in the client
5161 library. Affected file lib/silcclient/client_notify.c. Also,
5162 implemnted the printing of the SERVER_SIGNOFF info to the
5163 application. Affected file silc/client_ops.c.
5165 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5166 if the deleting was successful. Affected file silcd/idlist.[ch].
5168 * Added support for public key authentication in the connection
5169 authentication protocol in the client library. Affected file
5170 lib/silcclient/protocol.c.
5172 * Changed the server's silc_idlist_get_clients_by_* interface
5173 to support already allocated array so that new entries may be
5174 added to pre-allocated array. Affected file silcd/idlist.[ch].
5175 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5176 and command replies.
5178 * All command reply functions in the server now calls the
5179 pending command callback even if error occured. This way the
5180 error will be delivered to the client as well. Affected files
5181 silcd/command.c and silcd/command_reply.c.
5183 * Fixed INFO command to return local server's info if no server
5184 was provided. Affected file lib/silcclient/command.c.
5186 * Removed RESTART command for good. Updated the code and the
5189 * Rewrote parts of the task system. It is a bit simpler now.
5190 Removed unsued task priorities. The affected files are
5191 lib/silcutil/silctask.[ch].
5193 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Moved the USERS printing from the library to the application.
5196 Affected files lib/silcclient/command.c and silc/client_ops.c.
5198 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Added channel key re-key support. The re-key is perfomed
5203 only by the router and is done once in an hour. Added `rekey'
5204 field to the SilcChannelEntry in the server. Affected files
5205 silcd/server.c and silcd/idlist.h.
5207 * Added silc_task_unregister_by_context into the file
5208 lib/silcutil/silctask.[ch].
5210 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Added SILC_UMODE_GONE mode to indicate when the client is not
5213 present in the SILC network. Added also support to the local
5214 command AWAY that will set this mode. Added support of showing
5215 "xxx is gone" in WHOIS command. The USERS command shows the
5216 gone status as well.
5218 * Fixed setting server and router operator privileges in the
5219 server's UMODE command. Affected file silcd/command.c.
5221 * Merged the SKE KE1 and KE2 payloads into one payload. The
5222 new KE payload is equivalent to the old KE2 payload.
5224 Cleaned up the SKE Start Payload parsing. It now uses the
5225 simple buffer unformatting to do the parsing. A lot faster
5228 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5229 to the SKE that is used to indicate whether both of the SKE
5230 parties should perform authentication. By default only the
5231 responder performs authentication. By setting this flag also
5232 the initiator must do authentication. By default it is unset
5233 since in normal SKE case, client to server connection, only
5234 the responder should do authentication. When doing SKE between
5235 two clients both should perform authentication. Updated the
5236 code and the protocol specs.
5238 * A little fix to IDENTIFY command in the server. Search the
5239 client first by hash not nickname. Affected file is
5242 * Fixed the silc_client_close_connection to support closing
5243 the client to client connections wihtout deleting too much
5244 data. Affected file lib/silcclient/client.c.
5246 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5247 are received if protocol used to be active but is not anymore
5248 the application would crash due to NULL pointer dereference.
5249 Affected files silcd/server.c and lib/silcclient/client.c.
5251 * Added `hash' field to the SilcClientConnection to include
5252 the hash function negotiated in the SKE protocol.
5254 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5255 to set the channel founder authentication data. A client can
5256 claim the founder rights later by providing the authentication
5257 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5258 This way the channel founder can regain the channel founder
5259 privileges even it is left the channel. This works only on
5260 local server and the client must be connected to the same
5261 server to be able to regain the founder rights. Updated the
5262 protocol specs accordingly.
5264 Added support to the CMODE command in the client to set the
5265 founder auth data. Read the README to see how to set it.
5267 Added support to the CUMODE command to claim the founder
5268 rights. Read the README to see how to do it.
5270 Added support for the founder authentication to the Channel
5271 Entry in the server. Affected file silcd/idlist.h.
5273 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5274 server's CMODE command. Affected file silcd/command.c.
5276 * Added the following new functions into lib/silccore/silcauth.[ch]:
5277 silc_auth_get_method and silc_auth_get_data.
5279 * The server now saves the remote hosts public key to the
5280 SilcIDListData pointer. Affected file silcd/protocol.c.
5282 * The normal server now does not remove the channel entry from
5283 the cache if the founder authentication data is set. It used
5284 to remove it if the founder was the last one on the channel on
5285 the server and left the channel. The auth data is saved and
5286 if the channel is re-joined later the old entry is used with
5287 the old auth data. Affected files silcd/command_reply.c and
5290 * Removed the `pkcs' field from the SilcIDListData structure
5291 in the server; it is not used. Affected file silcd/idlist.h.
5293 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Fixed packet processing on slow links. Partial packets were
5296 never re-processed because the incoming data buffer was cleared
5297 by the application. Application must not directly clear the
5298 sock->inbuf, the packet processing routines handle it. Fixed
5299 this in client library and in server.
5301 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed the WHOIS and IDENTIFY send reply function to really
5304 check whether to send list or just one entry. Affected file
5307 * Cleaned up the LEAVE command's channel key distribution. The
5308 affected file silcd/command.c.
5310 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5311 can enforce the channel mode as well. In that case the ID
5312 includes the ID of the server. The code now enforces the
5313 mode change if the router have different mode than the server.
5315 * The notify client operation with CMODE_CHANGE notify can now
5316 return NULL client_entry pointer if the CMODE was not changed
5317 by client. Application must check for this.
5319 * Added <Server ID> argument to INFO command to support server
5320 info fetching by Server ID.
5322 * Added silc_server_announce_get_channel_users to get assembled
5323 packets of channel users of the specified channel. Affected
5324 file silcd/server.[ch].
5326 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5327 was freed underneath the ID Cache.
5329 * Re-announce clients when the server received CHANNEL_CHANGE
5330 notify from the router. Affected file silcd/packet_send.c.
5332 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5335 crashed since it did not handle the fact that there is no cipher
5336 called "3" and didn't check the error condition. Now fixed.
5338 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5339 flag. It can be used to send message requests.
5341 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Implemented the RESTART command in the client.
5345 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5346 notice type messages. Added notice printing to the user
5349 * The channel keys are not re-generated if the channel's mode
5350 is PRIVKEY, ie private key on the channel exists. Affected
5351 files silcd/server.c and silcd/command.c.
5353 * Fixed a little bug in channel message delivery when channel
5354 private keys are set in the server. Affected file is
5355 silcd/packet_send.c.
5357 * Changed the setting on channel->on_channel = TRUE from the
5358 silc_client_save_channel_key to the JOIN command reply. The
5359 key payload is not received if the private channel key is set.
5360 Affected file lib/silcclient/command_reply.c and the
5361 lib/silcclient/client_channel.c.
5363 * When the CMODE_CHANGE notify is sent and the channel private
5364 key mode is removed the channel key must be re-generated in
5365 other cells as well. Added this support for the router in the
5366 silcd/packet_receive.c.
5368 * Added new local command NOTICE to send notice message on
5369 channel. Affected file silc/local_command.[ch].
5371 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Added new local command ME to the client. It is used to send
5374 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5375 some action. Affected file silc/local_command.[ch].
5377 * Changed channel_message and private_message client operations
5378 to deliver the message flags to the application. Added also
5379 the `flags' arguments to the silc_client_send_channel_message
5380 and silc_client_send_private_message functions. Affected file
5383 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Redefined the Private Message Payload to support private message
5386 keys and to support the new private message flags. Updated
5387 the protocol specs. Flags makes it possible to have for example
5388 CTCP style messages.
5390 * Added new type SilcPrivateMessagePayload and defined an API
5391 for it in the lib/silcclient/silcprivate.[ch].
5393 * Tested private message private keys successfully. Tested the
5394 private message key set, unset and list commands with the new
5397 * Redefined the Channel Message Payload to include the channel
5398 message flags (equal with private message flags) to support
5399 for example CTCP style messages.
5401 * Defined some of the message (for channel and private message)
5402 flags. Updated the protocol specs and added the flags to the
5403 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5405 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added SilcKeyAgreementStatus type to the key agreement routines
5408 to indicate the current status and error if one occured.
5409 The status types are defined in the lib/silcclient/silcapi.h.
5411 * Added new local command KEY that is used to set and unset private
5412 keys for channels, set and unset private keys for private messages
5413 with remote clients and to send key agreement requests and
5414 negotiate the key agreement protocol with remote client. The
5415 key agreement is supported only to negotiate private message keys,
5416 it currently cannot be used to negotiate private keys for channels,
5417 as it is not convenient for that purpose.
5419 * Fixed a minor pending callback setting bug in the function
5420 silc_client_get_client_by_id_resolve, now the function works.
5421 Affected file lib/silcclient/idlist.c.
5423 * Added function silc_net_get_local_port to get local bound
5424 port by socket. Added to lib/silcutil/silcnet.[ch].
5426 * Added `sockets' and `sockets_count' fields to the SilcClient
5427 object. They hold the sockets of the listenning sockets in
5428 the client. Listenning sockets may be for example the key
5429 agreement server. Affected file lib/silcclient/client.[ch].
5430 Added functions the silc_client_add_socket and the
5431 silc_client_del_socket. They are exported to the application
5434 * Added ~./silc/clientkeys to support other client's public keys.
5436 * Renamed verify_server_key client operation to verify_public_key
5437 and added one argument to indicate the type of the connection
5438 (server, client etc.).
5440 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Added silc_server_connection_auth_request to handle the
5443 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5444 silcd/packet_receive.[ch].
5446 * Added silc_server_send_connection_auth_request into the
5447 silcd/packet_send.c to send the connection auth request packet.
5449 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5452 * Fixed the public key authentication in responder side in the
5453 server. The `auth_data' pointer includes the SilcPublicKey
5454 not the path to the public key. Affected file silcd/protocol.c.
5456 * Implemented the public key authentication in the initiator side
5457 in the server. Affected file silcd/protocol.c.
5459 * Removed the [RedirectClient] config section from the server
5460 configuration. Is not needed and I don't want to implement it.
5462 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Cleaned up the CMODE command in the server. It now works
5465 correctly and supports all the modes defined in the protocol.
5466 Affected file is silcd/command.c.
5468 * Added `hmac_name' field to the SilcChannelEntry in the server
5469 to hold the default HMAC of the channel. It can be set when
5470 creating the channel (with JOIN command). Affected files
5473 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5474 type to indicate the change of the current cipher and hmac
5475 on the channel. Client can safely ignore the <cipher> argument
5476 (if it chooses to do so) since the CHANNEL_KEY packet will
5477 force the channel key change anyway. The <hmac> argument is
5478 important since the client is responsible of setting the new
5479 HMAC and the hmac key into use.
5481 * Fixed the CMODE command in the client library as well.
5483 * Tested CMODE command in router environment successfully.
5485 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Show the version of the remote client (or server) when connecting
5488 to the server. It is logged to the log file. Affected file
5489 is silcd/protocol.c.
5491 * Fixed the KILLED notify handling in the client library. The
5492 client must be removed from all channels when receiving the
5495 Also, do not remove the client entry when giving the KILL
5496 command but when the KILLED notify is received.
5498 * Removed silc_idlist_find_client_by_nickname from the server.
5499 Not needed anymore. Affected files silcd/idlist.[ch].
5501 * Implemented the CHANNEL_CHANGE notify type handling to the
5502 server. Affected file silcd/server.c.
5506 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Added silc_server_send_notify_invite to send the INVITE
5509 notify between routers.
5511 * Implemented the INVITE command correctly to the server.
5513 * Implemented the INVITE notify type handling in the server.
5515 * Implemented the INVITE command to the client library and on the
5518 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Added function silc_server_get_client_resolve to find the
5521 client entry by ID from all ID lists and then resolve it
5522 (using WHOIS) if it cannot be found. Affected file is
5525 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Implemented the BAN command to the client library.
5529 * The JOIN command in the server now checks the invite list
5532 * Changed the silc_command_reply_payload_encode_va and the
5533 silc_command_payload_encode_va to support that if argument is
5534 NULL it ignores and checks the next argument. Affected file
5535 lib/silccore/silccommand.c.
5537 * Added silc_server_send_notify_ban to send the BAN notify
5538 type between routers.
5540 * Chaned the silc_notify_payload_encode to support that if
5541 argument is NULL it ignores and checks the next argument.
5542 Affected file lib/silccore/silcnotify.c.
5544 * Tested ban lists in router environment successfully.
5546 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Implemented BAN command to the server, in silcd/command.[ch].
5550 * Removed the BAN and INVITE_LIST modes from the CMODE command
5553 * Added function silc_string_match to regex match two strings.
5554 Affected files lib/silcutil/silcutil.[ch].
5556 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Redefined parts of the SilcChannelEntry in the server to support
5559 the new ban and invite lists.
5561 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Redefined the INVITE command. The same command can be used to
5564 invite individuals to the channel but also to manage the invite
5565 list of the channel (to add to and remove from the invite list).
5566 Updated the protocol specs.
5568 * Added new command SILC_COMMAND_BAN that can be used to manage
5569 the ban list of the channel. Updated the protocol specs.
5571 * Removed the channel modes: the SILC_CMODE_BAN and the
5572 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5573 in the CMODE command. The equivalent features are now available
5574 using INVITE and BAN commands. Updated the protocol specs.
5576 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5577 in the network about change in the current ban list. The notify
5578 type is not used by the client.
5580 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5581 support the invite lists.
5583 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added new function silc_string_regexify that converts string
5586 including wildcard characters into regex string that can
5587 be used by the GNU regex library. Added into the file
5588 lib/silcutil/silcutil.[ch].
5590 Added silc_string_regex_combine to combine to regex strings
5591 into one so that they can be used as one regex string by
5592 the GNU regex library. Added into the file
5593 lib/silcutil/silcutil.[ch].
5595 Added silc_string_regex_match to match two strings. It returns
5596 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5598 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Imported GNU regex to the soruce tree into lib/contrib.
5601 Fixed some compiler warning from the regex.c.
5603 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Fixed MOTD command in the server to work in router environment.
5607 * Fixed the MOTD command in the client library to support
5608 the server argument in the command.
5610 * Added `nickname_len' argument to the silc_idlist_add_client
5611 in the server, as the `nickname' argument may be binary data
5614 * Added silc_idlist_get_channels to return all channels from
5617 * Implemented LIST command to the server. Affected file is
5620 * Implemented the LIST command to the client library and on the
5623 * Added [<user count>] argument to the LIST command reply.
5624 With private channels the user count is not shown.
5626 * Updated TODO and README.
5628 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * The client entry's data.registered must be TRUE even with
5631 global client entry on global client list. The data.registered
5632 is used to check whether the client is anymore in the network,
5633 for example with WHOWAS command so it must be valid.
5635 * Fixed the WHOWAS command in the server. It now actually works
5636 in router environment. Added function into silcd/command_reply.c
5637 silc_server_command_reply_whowas_save.
5639 * Added silc_idlist_purge function to the silcd/idlist.c
5640 to periodically purge the ID Cache.
5642 * Fixed INFO command in the server. It works now in router
5643 environment. Added <server name> argument to the INFO command
5644 reply. Updated the protocol specs.
5646 * Fixed minor bug in silc_idcache_purge to not purge if the
5647 expire value is zero.
5649 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5650 they were buggy because of the WHOWAS information.
5652 * Fixed local command MSG to handle the async resolving of
5653 the remote client properly. It used to fail the first MSG.
5654 Affected file silc/local_command.c.
5656 * Added `data_len' field to SilcIDCache context.
5658 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Update TODO. Todo in commands in the server.
5662 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5665 used by routers as broadcast packet to inform other routers
5666 about the changed user mode.
5668 Implemented the notify handling in the server. Affected file is
5669 silcd/packet_receive.c. Added the function
5670 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5672 * Added new generic Channel Payload and deprecated the New Channel
5673 Payload. The New Channel Payload is now the generic Channel
5676 * Added new argument `mode' to the silc_server_send_new_channel
5677 as it is required in the Channel Payload now.
5679 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5680 and created a new and real SilChannelPayload to represent the
5681 new generic Channel Payload. Implemented the encode/decode
5682 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5684 * Added silc_server_get_client_channel_list to return the list
5685 of channels the client has joined for WHOIS command reply.
5686 Affected file silcd/server.[ch].
5688 * Implemented the channel list sending in the WHOIS command reply
5689 in server and in the client.
5691 Implemented the channel list displaying on the user interface
5692 as well. Affected file silc/client_ops.c.
5694 * Added silc_channel_payload_parse_list to parse list of Channel
5695 Payloads. It returns SilcDList list of SilcChannelPayloads.
5696 Client for example can use this function to parse the list of
5697 channels it receives in the WHOIS command reply. The caller
5698 must free the list by calling silc_channel_payload_list_free.
5699 Affected files lib/silccore/silcchannel.[ch].
5701 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Added one new argument <user mode> to the WHOIS command reply
5704 to return the mode of the user in SILC. Updated the protocol
5707 Implemented it to the server and client.
5709 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Fixed the mode printing on the user interface on joining.
5712 Affected file silc/client_ops.c.
5714 * Implemented the UMODE command and user modes in general to the
5715 client library and to the user interface.
5717 * Implemented the UMODE command to the server.
5719 * The server now sends UNKNOWN_COMMAND error status if client sends
5720 unknown command. Affected file silcd/command.c.
5722 * All server commands now handle the command identifier the right
5723 way when sending the command reply to the client. The client can
5724 use to identify the command replies with the identifier.
5726 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Added silc_server_get_client_route to resolve the route to
5729 the client indicated by the client ID. Affected file is
5732 * Added silc_server_relay_packet as general function to relay
5733 packet to arbitrary destination. This deprecates functions
5734 like _send_private_message_key, _relay_notify etc. Affected
5735 file is silcd/packet_send.[ch].
5737 Removed silc_server_send_key_agreement,
5738 silc_server_send_private_message_key and
5739 silc_server_packet_relay_notify functions from the file
5740 silcd/packet_send.[ch].
5744 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5745 server. Affected file silcd/packet_receive.[ch].
5747 * Implemented the KILL command to the client. Implemented the
5748 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5749 Affected files lib/silcclient/command[_reply].c and
5750 lib/silcclient/client_notify.c. Implemented the KILL notify
5751 printing in the user inteface.
5753 * Fixed a lot silc_parse_nick memory leaks from the client
5754 library in the file lib/silcclient/command.c.
5756 * Changed the silc_server_send_notify_on_channels's `sender'
5757 argument from SilcSocketConnection to SilcClientEntry to
5758 check the sender as entry and not as connection object and not
5759 to send to the client provided as argument. The affected file
5760 is silcd/packet_send.[ch].
5762 * The notify packets that are destined directly to the client used
5763 to not to be processed by the server. Now changed that and the
5764 server processes all notify packets. After relaying the packet
5765 to the client the notify packet is processed in the server.
5767 * The silc_server_free_client_data now checks whether there is
5768 pending outgoing traffic for the client and purges the data to
5769 the network before removing the client entry.
5771 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5774 an client is killed from the SILC Network. Updated the protocol
5777 Added new function silc_server_send_notify_killed to the
5778 silcd/packet_send.[ch].
5780 * Added function silc_server_packet_relay_notify to relay notify
5781 packets that are destined directly to a client. In this case
5782 the server does not process the notify packets but merely relays
5783 it to the client. Affected file silcd/packet_send.[ch].
5785 Added also silc_server_packet_process_relay_notify to check
5786 whereto relay the notify. Affected file is
5787 silcd/packet_receive.[ch].
5789 * Implemented the KILL command to the server.
5793 * Added the backup schema desgined last fall to the protocol
5794 specs for everyone to see. The specification is in the
5795 *-spec-xx.txt draft and the packet type definitions for the
5796 backup routers is in *-pp-xx.txt draft. Thusly, added also
5797 new packet type SILC_PACKET_CELL_ROUTERS.
5799 * A big security problem in the implementation discovered. The
5800 signoff of an client did not cause new channel key generation
5801 which it of course should've done. The channel keys must be
5802 always re-generated when client leaves (or signoffs) the channel.
5803 The silc_server_remove_from_channels funtion now handles
5804 the channel key re-generation.
5806 * Added `sender' argument to the silc_server_send_notify_on_channels
5807 to not to send the client provided as argument. Affected file
5808 silcd/packet_send.[ch].
5810 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Implemented OPER and SILCOPER commands into the server and
5815 * Added silc_auth_verify and silc_auth_verify_data to verify
5816 the authentication directly from the authentication payload.
5817 It supports verifying both passphrase and public key based
5818 authentication. Affected file lib/silccore/silcauth.[ch].
5820 * Added `hash' field to the SilcIDListData structure. It is the
5821 hash negotiated in the SKE protocol. Affected file is
5824 * Slight redesigning of the SilcAuthPayload handling routines.
5825 Do not send SilcPKCS but SilcPublicKey as argument.
5827 * Implemented the public key authentication support to the
5828 serverconfig. The public key is loaded from the provided path
5829 and saved as authentication data to void * pointer. Thus,
5830 changed the unsigned char *auth_data to void *auth_data;
5832 * Fixed SHUTDOWN command to send the reply before the server
5833 is shutdown. :) Affected file silcd/command.c.
5835 * Fixed fatal bug in CONNECT command. The hostname was invalid
5836 memory and server crashed. Affected file silcd/command.c.
5838 * Fixed fatal bug in CLOSE command. The server_entry became
5839 invalid but was referenced later in the command. Affected file
5842 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Fixed fatal bug in failure packet handling. Server ignored
5845 the failure and thus crashed when it came.
5849 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5852 that the command may be executed only once in (about) 2 seconds.
5853 The old SILC_CF_LAG flag is same but allows command bursts up
5854 to five before limiting.
5856 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5857 server code. Various commands now includes the CF_LAG_STRICT
5858 flag to disallow any kind of miss-use of the command.
5860 * Fixed the silc_buffer_unformat to not to allocate any data
5861 if the length of the data is zero. It used to allocate the
5862 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5864 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Changed the format of AdminConnection configuration section
5867 in the server. Added username of the admin to the format.
5868 Affected files silcd/serverconfig.[ch].
5870 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5871 to return admin configuration data by host, username and/or
5874 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5876 * Implemented WHOWAS command to the server. Added the functions:
5878 silc_server_command_whowas_parse,
5879 silc_server_command_whowas_send_reply,
5880 silc_server_command_whowas_from_client and
5881 silc_server_command_whowas_from_server
5883 * Added <Client ID> argument to the WHOWAS command reply. Updated
5884 the protocol specs accordingly.
5886 * Implemented WHOWAS command and command_reply to the client
5889 Implemented the WHOWAS printing on the user interface.
5891 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Added new argument to the WHOWAS command reply, the real name.
5894 It is an optional argument. Updated the protocol specs.
5896 * Added SilcIDCacheDestructor callback that is registered when
5897 the SilcIDCache is allocated. The callback is called when
5898 an cache entry in the ID Cache expires, or is purged from the
5899 cache. Added into lib/silccore/idcache.[ch].
5901 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5902 to destruct the client entries when the cache entry expires.
5903 Other ID Cache's in server and in the client library ignores
5906 * If the ID Cache entry's `expire' field is zero then the entry
5907 never expires. Added boolean `expire' argument to the
5908 silc_idcache_add function in the lib/silccore/idcache.[ch].
5909 If it is TRUE the default expiry value is used.
5911 * Added silc_server_free_client_data_timeout that is registered
5912 when client disconnects. By default for 5 minutes we preserve
5913 the client entry for history - for WHOWAS command.
5915 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Added support to the server to enforce that commands are not
5918 executed more than once in 2 seconds. If server receives
5919 commands from client more frequently, timeout is registered
5920 to process the commands. Affected file silcd/command.c.
5921 Added new function silc_server_command_process_timeout.
5923 * Changed NICK_NOTIFY handling in client library to check that
5924 if the client's nickname was changed, so there is no need to
5925 resolve anything from the server.
5927 * Removed error printing from the WHOIS and IDENTIFY commands.
5928 If error occurs then it is ignored silently in the client library.
5929 The application, however, may map the received error to
5930 human readable error string. The application currently maps
5931 the NO_SUCH_NICKNAME error to string.
5933 * Made the command status message public to the application. Moved
5934 them from lib/silcclient/command_reply.c to
5935 lib/silcclient/command_reply.h. The application can map the
5936 received command status to the string with the
5937 silc_client_command_status_message function.
5939 * Added check to the server to check that client's ID is same
5940 as the Source ID in the packet the client sent. They must
5943 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Added dist-bzip hook to the Makefile.am to make bzip2
5946 compressed distributions.
5948 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Server now enforces the maximum length for the nickname and
5951 the channel as protocol specification dictates. 128 bytes for
5952 nickname and 256 bytes for channel name.
5954 * Moved the WHOIS printing to the application. The client libary
5955 does not print out the WHOIS information anymore, the application
5956 must do it. Renamed silc_client_command_reply_whois_print to
5957 the silc_client_command_reply_whois_save.
5959 The client's idle time is also sent to the application now, and
5960 the idle is shown on screen.
5962 * Added silc_client_command_reply_identify_save to save the
5963 received IDENTIFY entries.
5965 * Do not check for channel private keys in message sending and
5966 reception if the channel does not have the PRIVKEY mode set.
5967 Affected file lib/silclient/client_channel.c.
5969 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5972 just surfaced after chaning the JOIN procedure.
5974 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added silc_client_get_clients_by_list to get client entries
5977 from Client ID list, that is returned for example by JOIN
5978 and USERS command replies. The application should use this
5979 function for example when JOIN command reply is received to
5980 resolve the clients already on the channel (library does not
5981 do that anymore as USERS command reply is not used in the JOIN
5982 procedure anymore). Affected files lib/silcclient/silcapi.h and
5983 lib/silcclient/idlist.c.
5985 * JOIN command reply and USERS command reply returns now SilcBuffer
5986 pointers instead of unsigned char pointers when returning
5987 the client list and mode list.
5989 * Added <Client ID> argument to the JOIN command reply, mainly
5990 for the server to identify for which client the command was
5991 originally sent. Updated protocol specs accordingly.
5993 * Added SilcDlist private_key pointer to the SilcChannelEntry
5994 in the client to support the channel private keys. Affected
5995 file is lib/silcclient/idlist.h.
5997 * Added SilcChannelPrivateKey argument to the function
5998 silc_client_send_channel_message so that application can choose
5999 to use specific private ke if it wants to. If it is not provided,
6000 the normal channel key is used, unless private keys are set.
6001 In this case the first (key that was added first) is used
6002 as the encryption key.
6004 * Implemented the support for channel private key handling.
6005 Implemented the following functions:
6007 silc_client_add_channel_private_key,
6008 silc_client_del_channel_private_keys,
6009 silc_client_del_channel_private_key,
6010 silc_client_list_channel_private_keys and
6011 silc_client_free_channel_private_keys
6013 Affected file lib/silcclient/client_channel.c.
6015 * Added the support for the private keys in the channel message
6016 sending and encryption and in the message reception and
6017 decryption. Affected funtions are
6018 silc_client_send_channel_message and silc_client_channel_message.
6020 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Added SKE's key verify callback to the client library's
6023 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6025 * Removed the statement that server (or router) must send USERS
6026 command reply when joining to the channel so that the client
6027 knows who are on the channel. Instead, the client list and
6028 client's mode list is now sent in the JOIN command reply to the
6029 client who joined channel. This is better solution.
6031 * Added function silc_server_get_users_on_channel and function
6032 silc_server_save_users_on_channel to the silcd/server.[ch].
6034 * Removed function silc_server_command_send_users from the
6037 * Do not show topic on the client library anymore. The topic is
6038 sent in the command reply notify to the application and the
6039 application must show the topic now.
6041 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added client searching by nickname hash into the IDENTIFY and
6044 WHOIS commands in the server as they were clearly missing from
6045 them. Affected file is silcd/command.c.
6047 * Fixed a bug in private message receiving in the client library.
6048 The remote ID was freed and it wasn't supposed, now it is
6051 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Minor fix to the channel payload; allocate the data area, as it
6054 needs to be of specific length.
6056 * If the key agreement port is zero then the operating
6057 system will define the bound port. Affected files are
6058 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6060 * Added new function silc_channel_payload_decrypt into the file
6061 lib/silccore/silcchannel.[ch].
6063 * Moved the channel message etc, check from silc_packet_decrypt
6064 to applications. The library calls now a generic
6065 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6066 when the packet is either normal or special. This was done to
6067 allow more wide range of checking that was not allowed when
6068 the code was in library. Now applications can do virtually any
6069 checks to the packet and return to the library the decision how
6070 the packet should be processed. Affected files are
6071 lib/silccore/silcpacket.[ch].
6073 Added silc_server_packet_decrypt_check to the server and
6074 silc_client_packet_decrypt_check to the client library.
6076 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6077 to send with specified source and destination information.
6079 * Channel message delivery between routers was broken after the
6080 channel key distribution was fixed earlier. The channel key
6081 was used be to distributed to other routers as well which is not
6082 allowed by the protocol. Now this is fixed and channel keys
6083 really are cell specific and the channel message delivery between
6084 routers comply with the protocol specification.
6086 * Fixed various commands in server to check also the global list
6087 for the channel entry and not just the local list. The affected
6088 file silcd/command.c.
6090 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Added assert()s to buffer formatting and unformatting routines
6093 to assert (if --enable-debug) when error occurs. Affected
6094 file: lib/silcutil/silcbuffmt.c.
6096 * Changed to auto-reconnect to check whether the remote host is
6097 router and register the re-connect timeout if it is. It used
6098 to check that whether we are normal server, but router must do
6099 auto-reconnect with another router as well. Affected file
6102 * Removed the [<key len>] option from CMODE command as the cipher
6103 name decides the key length, nowadays. See the defined ciphers
6104 from the protocol specification.
6106 * Added [<hmac>] option to the CMODE command to define the HMAC
6107 for the channel. Added SILC_CMODE_HMAC channel mode.
6109 * Added [<hmac>] option for the JOIN command so that user can
6110 select which HMAC is used to compute the MACs of the channel
6113 * Added Hmac field to the Channel Message Payload. The integrity
6114 of plaintext channel messages are now protected by computing
6115 MAC of the message and attaching the MAC to the payload. The
6116 MAC is encrypted. Now, it is clear that this causes some
6117 overhead to the size of the packet but rationale for this is that
6118 now the receiver can verify whether the channel message decrypted
6119 correctly and also when private keys are set for the channel the
6120 receiver can decrypt the packet with several keys and check from
6121 the MAC which key decrypted the message correctly.
6123 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6124 lib/silccrypt/silccipher.[ch].
6126 * Added silc_hash_len to return the digest length into the
6127 lib/silcrypt/silchash.[ch].
6129 * Rewrote parts of Silc Channel Payload interface in the
6130 lib/silccore/silcchannel.[ch]. The encode function now also
6131 encrypts the packet and parse function decrypts it.
6133 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed a minor formatting bug in the SKE's key material processing.
6136 It actually might have processed the keys wrong way resulting
6139 * Redefined the mandatory HMAC algorithms and added new algorithms.
6140 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6141 and hmac-md5 truncated to 96 bits. The mandatory is now
6142 hmac-sha1-96. Rest are optional (including the one that used
6143 to be mandatory). Rationale for this is that the truncated HMAC
6144 length is sufficient from security point of view and can actually
6145 make the attack against the HMAC harder. Also, the truncated
6146 HMAC causes less overhead to the packets. See the RFC2104 for
6149 * Added new [hmac] configuration section. The SKE used to use
6150 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6151 is of course wrong. The official names that must be proposed in
6152 the SKE are the ones defined in the protocol specification
6153 (hmac-sha1-96 for example). The user can configure any hmac
6154 using any hash function configured in the [hash] section. At
6155 least, the mandatory must be configured.
6157 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6159 * Added HMAC list to the SKE proposal list. It has now both
6160 hash algorithm list and HMAC list. This makes the protocol
6161 incompatible with previous versions. The SKE now seems to work
6162 the way it is supposed to work, for the first time actually.
6164 * Defined plain Hash algorithms to the protocol specification.
6167 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Implemented support for key agreement packets into the server.
6170 Added functions silc_server_key_agreement and
6171 silc_server_send_key_agreement. Other than these functions,
6172 server has nothing to do with this packet.
6174 * Added support for private message key packets into the server.
6175 Added functions silc_server_private_message_key and
6176 silc_server_send_private_message_key.
6180 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6181 called in the protocol's final callback instead in the END
6182 protocol state. This makes a little more sense and in the same
6183 time in client we can use the same protocol routines for normal
6184 key exchange and to key agreement packet handling as well.
6186 * Added to both client's and server's KE protocol context the
6187 SilcSKEKeyMaterial pointer to save the key material. We will
6188 bring the key material to the protocol's final callback by doing
6189 this. The final callback must free the key material.
6191 * Added SKE's packet_send callback into client's KE protocol
6192 context so that the caller can choose what packet sending function
6193 is used. This way we can use different packet sending when
6194 doing normal SKE when doing key agreement packet handling (in
6195 the key agreement packet handling we do not want to encrypt
6198 * Implemented the responder side of the key agreement routines
6199 in the client. The client can now bind to specified port and
6200 accept incoming key negotiation. The key material is passed
6201 to the application after the protocol is over.
6203 * Implemented the processing of incoming Key Agreement packet
6204 in the client. Added function silc_client_key_agreement to
6207 * Implemented the intiator side of the key agreement routines
6208 in the client. The client can now initiate key agreement with
6209 another remote client. The key material is passed to the
6210 application after the protocol is over.
6212 * Created client_keyagr.c to include all the key agreement
6215 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6216 SILC_TASK_CALLBACK except that it is not static.
6218 * Created client_notify.c and moved the Notify packet handling
6219 from the client.[ch] into that file.
6221 * Created client_prvmsg.c and moved all private message and
6222 private message key routines from the client.[ch] into that file.
6224 * Create client_channel.c and moved all channel message and
6225 channel private key routines from the client.[ch] into that file.
6227 * Changed silc_client_get_client_by_id_resolve to resolve with
6228 WHOIS command instead of IDENTIFY command, in the file
6229 lib/silclient/idlist.c.
6231 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Implemented the SKE's responder side to the Client library.
6235 * When FAILURE is received to the protocol do not trust it
6236 blindly. Register a timeout to wait whether the remote closes
6237 the connection as it should do it, only after that process the
6238 actual failure. This was changed to both client and server.
6240 * Added client_internal.h to include some of the structures
6241 there instead of client.h in lib/silcclient/.
6243 * Added function silc_task_unregister_by_callback to unregister
6244 timeouts by the callback function.
6246 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6248 * Some "Incomplete WHOIS info" errors has been appearing on the
6249 log files. Took away the entry->userinfo check from WHOIS
6250 reply sending. The entry->userinfo is now " " if client did not
6251 provide one. I thought this was fixed earlier but something
6252 is wrong still. Let's see if the error still appears.
6254 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Fixed a minor bug in the login when the channel key is
6257 re-generated in the server. It used to generate the key in
6258 wrong order and thus caused problems in the channel traffic.
6260 * Fixed a minor bug in channel key distsribution after
6261 KICK command. The key was not sent to the router even though
6264 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Added silc_ske_process_key_material_data as generic routine
6267 to process any key material as the SILC protocol dictates. The
6268 function is used by the actual SKE library but can be used by
6269 applications as well. This relates to the private message keys
6270 and the channel private keys since they must be processed the
6271 same way the normal SILC session keys. The protocol dictates
6272 this. Affected files: lib/silcske/silcske.[ch].
6274 Added also silc_ske_free_key_material to free the
6275 SilcSKEKeyMaterial structure.
6277 * Defined silc_cipher_set_key function to set the key for
6278 cipher without using the object's method function. The affected
6279 files: lib/silccrypt/silccipher.[ch].
6281 * Implemented silc silc_client_add_private_message_key,
6282 silc_client_add_private_message_key_ske,
6283 silc_client_del_private_message_key,
6284 silc_client_list_private_message_keys and
6285 silc_client_free_private_message_keys functions in the
6288 Added functions silc_client_send_private_message_key to send
6289 the Private Message Key payload and silc_client_private_message_key
6290 to handle incoming Private Message Key payload.
6292 * Added Cipher field to the Private Message Key payload to set
6293 the cipher to be used. If ignored, the default cipher defined
6294 in the SILC protocol (aes-256-cbc) is used.
6296 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Removed lib/silcclient/ops.h file.
6300 Redefined parts of the SILC Client Library API. Created new
6301 file silcapi.h that deprecates the ops.h file and defines the
6302 published Client Library API. Defined also private message key
6303 API and channel private key API into the file.
6305 This is the file that the application must include from the
6306 SILC Client Library. Other files need not be included by
6307 the application anymore.
6309 * Added new key_agreement client operation callback and also
6310 defined the Key Agreement library API for the application.
6312 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6315 is used by clients to request key negotiation between another
6316 client in the SILC network. If the negotiation is started it
6317 is performed using the SKE protocol. The result of the
6318 negotiation, the secret key material, can be used for example
6319 as private message key.
6321 Implemented the Key Agreement payload into the files
6322 lib/silccore/silauth.[ch].
6324 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Redefined ciphers for the SILC protocol. Added some new ciphers
6327 and defined the key lengths for the algorithms. Changed the
6328 code accordingly. The default key length is now 256 bits.
6330 * Fixed SKE key distribution function silc_ske_process_key_material
6331 when the key length is more than 128 bits. The default key
6332 length in SILC is now 256 bits.
6334 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6335 to indicate unsupported algorithm.
6337 * Renamed rijndael.c to aes.c and all functions as well.
6339 * Fixed a long standing channel key setting bug in client library.
6340 Weird that it has never surfaced before.
6342 * Fixed bug in channel deletion. If the entire channel is removed
6343 then it must also delete the references of the channel entry
6344 from the client's channel list as the client's channel entry and
6345 the channel's client entry share same memory.
6347 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Implemented CONNECT and SHUTDOWN commands in the client.
6351 * Implemented CLOSE command to the client.
6353 * Added the function silc_idlist_find_server_by_name into the
6354 files silcd/idlist.[ch].
6356 Added the function silc_idlist_find_server_by_conn into the
6357 files silcd/idlist.[ch].
6359 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * DIE command was renamed to SHUTDOWN. Updated the both code
6364 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6365 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6367 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6370 * Added function silc_server_create_connection function to create
6371 connection to remote router. My server implementation actually
6372 does not allow router to connect to normal server (it expects
6373 that normal server always initiates the connection to the router)
6374 so the CONNECT command is only good for connecting to another
6377 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6380 or some other client was kicked from the channel.
6382 Implemented the handling of the notify type to both client
6385 Implemented silc_server_send_notify_kicked to send the KICKED
6386 notify. It is used to send it to the server's primary router.
6388 * Implemented the KICK command into server and client.
6390 * Added `query' argument to the silc_idlist_get_client function
6391 to indicate whether to query the client from server or not if
6394 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6395 to indicate that the client is not channel founder.
6399 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Removed the rng context from SilcPacketContext structure and
6402 changed that the packet routine uses the Global RNG API.
6404 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Added support for quit message that client can "leave" on the
6407 channel when it quits the SILC. It is ditributed inside the
6408 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6410 Added silc_server_free_client_data that will take the
6411 signoff message as argument.
6413 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6415 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Updated parts of the protocol specification to keep it up
6420 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6423 payloads in one packet.
6425 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6426 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6427 use now the new List flag.
6429 * Also deprecated the following packet types: REPLACE_ID,
6430 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6432 * Added list support for Notify packet in server.
6434 * Added silc_server_send_notify_channel_change to send the
6435 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6436 the silc_server_send_replace_id.
6438 * Added silc_server_send_notify_nick_change to send the
6439 NICK_CHANGE notify type. Deprecates the function
6440 silc_server_send_replace_id.
6442 * Added silc_server_send_notify_join to send the JOIN notify type.
6443 Deprecates the function silc_server_send_new_channel_user.
6445 * Added silc_server_send_notify_leave to send LEAVE notify type.
6446 Deprecates the function silc_server_send_remove_channel_user.
6448 * Added silc_server_send_notify_cmode and
6449 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6450 types. Deprecates the silc_server_send_set_mode function.
6452 * Added SERVER_SIGNOFF notify type to indicate that server has
6453 quit. This means that all clients on the channel from that
6454 server will drop. This can be also used when netsplit happens.
6456 Deprecated REMOVE_ID packet type since it is not needed anymore
6459 Added silc_server_send_notify_server_signoff to send the
6460 SERVER_SIGNOFF notify type. Deprecates the function
6461 silc_server_send_remove_id.
6463 Added also silc_server_send_notify_signoff to send the
6464 SIGNOFF notify type.
6466 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6467 SILC protocol from this day on. Changed the protocol
6468 specification as well.
6470 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6471 notify type. It is used between routers to notify about
6472 topic changes on a channel.
6474 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6477 * Partly updated the protocol specification to comply with the
6478 changes now made. It is still though a bit outdated.
6480 * The JOIN notify type now takes one extra argument <Channel ID>.
6481 The packet used to be destined to the channel but now the
6482 JOIN type may be sent as list thus it is impossible to
6483 destine it to any specific channel. By adding this argument
6484 it is again possible.
6486 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Added CREDITS file. The CHANGES and CREDITS file will appear
6489 in the distribution as well.
6491 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6494 types in the server's silcd/packet_receive.c.
6496 * Implemented CMODE and CUMODE to work in router environment.
6498 * Fixed minor encoding and decoding buglet from the
6499 lib/silccore/silcmode.c.
6501 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6504 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6506 * Changed all SilcConfigServer* and silc_config_server* to
6507 SilcServerConfig* and silc_server_config*, respectively.
6510 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Associated the ID (client or server ID) to the Authentication
6513 Payload to avoid any possibility of forging. Updated the
6514 protocol specification and the code accordingly.
6516 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * The RSA key length is now save to the RsaKey context in the
6519 key generation process in lib/silccrypt/rsa.c. The key length
6520 is now used to figure out the maximum size of the block allowed
6521 to be encrypted/signed.
6523 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6524 is equivalent to the silc_mp_mp2bin but does not allocate any
6527 * Changed silc_mp_mp2bin API to take length argument. If it is
6528 non-zero then the buffer is allocated that large. If zero, then
6529 the size is approximated using silc_mp_sizeinbase, which however
6532 * Created Global RNG API which is global RNG that application can
6533 initialize. After initializing, any routine anywhere in the
6534 code (including library) can use RNG without allocating a new
6535 RNG object. This was done to allow this sort of use of the
6536 RNG in code that has no chance to allocate RNG object. All
6537 applications currently allocate this and many routines in the
6538 library use this. Affected file lib/silccrypt/silcrng.[ch].
6540 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6541 it to use the Global RNG API.
6543 * Defined Authentication Payload into protocol specification that
6544 is used during SILC session to authenticate entities. It is
6545 used for example by client to authenticate itself to the server
6546 to obtain server operator privileges.
6548 Implemented this payload into the lib/silccore/silcauth.[ch].
6549 Implemented also routines for public key based authentication
6550 as the new protocol specification dictates.
6552 Moved definitions of different authentication methods from
6553 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6555 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6556 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6557 silc_pkcs_verify_with_hash functions into the file
6558 lib/silccrypt/silcpkcs.[ch].
6560 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * The client entry's userinfo pointer must be always valid.
6563 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6564 will fail since it requires the userinfo. Now, the userinfo
6565 is allocated as "" if actual userinfo does not exist. Actually,
6566 it must exist and it is totally Ok to drop client connections
6567 that does not announce the userinfo. However, we will make
6568 this workaround for now.
6570 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6571 to return the remote port by socket.
6573 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6576 SILC_SERVER_PENDING_EXEC and added an new macro
6577 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6578 data or when error occurs while processing the pending command.
6580 Added new argument `destructor' into silc_server_command_pending
6581 and to the SilcServerCommandPending object. This destructor is
6582 now called after calling the pending callback or if error occurs
6583 immediately. If error occurs the actual pending callback won't
6584 be called at all - only the destructor. The destructor may be
6585 NULL if destructor is not needed.
6587 All this applies for client library code as well. Similar
6588 changes were made there as well for the pending commands.
6590 In the client, the application must now allocate the
6591 SilcClientCommandContext with the silc_client_command_alloc
6594 * Added reference counter to the SilcServerCommandContext. Added
6595 function silc_server_command_alloc and silc_server_command_dup
6598 Same type of functions added to the client library for the same
6601 * Removed the cmd_ident from IDListData away since it is now
6602 global for all connections. It is the command identifier used
6603 in command sending and with pending commands. The affected file
6606 * Added reference counter to the SilcSocketConnection objecet to
6607 indicate the usage count of the object. The object won't be
6608 freed untill the reference counter hits zero. Currently only
6609 server uses this, and client ignores it. The client must be
6610 set to use this too later. The affected files are
6611 lib/silccore/silcsockconn.[ch]. Added also the function
6612 silc_socket_dup to increase the reference counter.
6614 This was mainly added because it is possible that the socket
6615 is removed underneath of pending command or other async
6616 operation. Now it won't be free'd and proper DISCONNECTING
6617 flags, etc. can be set to avoid sending data to connection that
6618 is not valid anymore.
6620 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6621 the connection. After that it sets SILC_SET_DISCONNECTED.
6622 It is, however, possible that the socket data is not still freed.
6623 The silc_server_packet_process now checks that data is not
6624 read or written to connection that is DISCONNECTED. The socket
6625 get's freed when the reference counter hits zero.
6627 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Changed the client operation API: channel_message operation's
6630 `sender' is now the client entry of the sender, not the nickname
6631 and the `channel' is the channel entry, not the channel name.
6633 In the private_message operation the `sender' is now also the
6634 client entry of the sender not the nickname.
6636 Affected file is lib/silcclient/ops.h and all applications
6637 using the client operations.
6639 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Moved the calling of ops->connect() from connect_to_server_final
6642 into receive_new_id functin since that is the point when the
6643 client is actually allowed to send traffic to network. The
6644 affected file is lib/silcclient/client.c.
6646 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6649 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6650 (if needs broadcasting) instead of broadcasting the packets one
6651 by one which would make a burst in the network traffic.
6653 * Added `broadcast' argument to the functions in silcd/server.[ch]
6654 silc_server_create_new_channel[_with_id] to indicate whether
6655 to send New Channel packet to primary router.
6657 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added new function into the silcd/server.[ch] files:
6660 silc_server_create_new_channel_with_id to create new channel with
6661 already existing Channel ID.
6663 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6664 lib/silccore/silcpacket.h. This packet is used t send list of
6665 Set Mode payloads inside one packet. Server uses this to set
6666 the modes for the channels and clients on those channels, that it
6667 announced to the router when it connected to it. The protocol
6668 specification has been updated accordingly.
6670 * The silc_server_new_channel did not handle the packet coming
6671 from normal server as it normally does not send that. However,
6672 when it announces its channels it does send it. Implemented
6673 the support for that.
6675 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6676 into the file lib/silccore/id.h.
6678 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Fixed memory leaks in the functions silc_idlist_del_client,
6681 silc_idlist_del_channel and silc_idlist_del_server in the file
6682 silcd/idlist.c. All of those leaked like a sieve.
6684 * Fixed some small memory leaks in the client's function
6685 silc_client_notify_by_server.
6687 * Added functions into silcd/server.c: silc_server_announce_clients,
6688 silc_server_announce_channels and silc_server_announce_server.
6689 These functions are used by normal and router server to announce
6690 to its primary router about clients, channels and servers (when
6691 router) that we own. This is done after we've connected to the
6694 These functions effectively implements the following packet types:
6695 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6696 and SILC_PACKET_NEW_ID_LIST.
6698 * Added new functions into the silcd/packet_receive.[ch]:
6699 silc_server_new_id_list, silc_server_new_channel_list and
6700 silc_server_new_channel_user_list to handle the incoming
6701 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6703 * Added support of changing Channel ID in the function
6704 silc_server_replace_id. If the server that announces a channel
6705 to the router already exists in the router (with same name but
6706 with different Channel ID), router is responsible to send
6707 Replace ID packet to the server and force the server to change
6708 the Channel ID to the one router has.
6710 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6711 client that the Channel ID has been changed by the router. The
6712 normal server sends this to the client. Client must start using
6713 the new Channel ID as the channel's ID.
6715 Implemented handling of this new type into lib/silcclient/client.c
6716 into the function silc_client_notify_by_server.
6718 * Added new function silc_idlist_replace_channel_id into the files
6719 silcd/idlist.[ch] to replace the Channel ID.
6721 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Call silc_server_command_identify_check always when processing
6724 the IDENTIFY command in silcd/command.c
6726 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6729 send keepalive packets. The packet can be sent by clients,
6730 servers and routers.
6732 Added function silc_socket_set_heartbeat into the file
6733 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6734 If not set, the heartbeat is not performed. The actual
6735 heartbeat is implemented in the low level socket connection
6736 library. However, application is responsible of actually
6739 Added silc_server_send_heartbeat to send the actual heartbeat
6740 packet into silcd/packet_send.[ch]. Server now performs
6741 keepalive with all connections.
6743 * Added silc_task_get_first function into lib/silcutil/silctask.c
6744 to return the timeout task with shortest timeout. There was a bug
6745 in task unregistration that caused problems. TODO has been
6746 updated to include that task system must be rewritten.
6748 * The client library will now resolve the client information when
6749 receiving JOIN notify from server for client that we know but
6750 have incomplete information.
6752 * Rewrote parts of silc_server_remove_from_channels and
6753 silc_server_remove_from_one_channel as they did not remove the
6754 channel in some circumstances even though they should've.
6756 * Encryption problem encountered in server:
6758 The LEAVE command used to send the Channel Key packet to the
6759 router immediately after generating it. However, the code
6760 had earlier sent Remove Channel user packet but not immediately,
6761 ie. it was put to queue. The order of packets in the router
6762 was that Channel Key packet was first and Remove Channel User
6763 packet was second, even though they were encrypted in the
6764 reverse order. For this reason, MAC check failed. Now, this
6765 is fixed by not sending the Channel Key packet immediately but
6766 putting it to queue. However, this is more fundamental problem:
6767 packets that are in queue should actually not be encrypted
6768 because packets that are sent immediately gets encrypted
6769 actually with wrong IV (and thus MAC check fails). So, packets
6770 that are in queue should be encrypted when they are sent to
6771 the wire and not when they put to the queue.
6773 However, the problem is that the current system has not been
6774 designed to work that way. Instead, the packet is encrypted
6775 as soon as possible and left to the queue. The queue is then
6776 just purged into wire. There won't be any fixes for this
6777 any time soon. So, the current semantic for packet sending
6780 o If you send packet to remote host and do not force the send
6781 (the packet will be in queue) then all subsequent packets to the
6782 same remote host must also be put to the queue. Only after the
6783 queue has been purged is it safe again to force the packet
6786 o If you send all packets immediately then it safe to send
6787 any of subsequent packets through the queue, however, after
6788 the first packet is put to queue then any subsequent packets
6789 must also be put to the queue.
6791 Follow these rules and everything works fine.
6793 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Added new function silc_server_remove_clients_by_server to
6796 remove all client entries from ID list when the server connection
6797 is lost. In this case it is also important to invalidate all
6798 client entires as they hold the invalid server entry. This
6799 fixes fatal bug when server has lost connection and will reconnect
6802 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Made some sanity checks to silc_server_daemonise like to check
6805 whether the requested user and group actually exists.
6807 * Added sanity check to SKE's silc_ske_responder_finish to check
6808 that the public and private key actually is valid.
6810 * Invalidate the client's nickname when receiving Replace ID
6811 packet and the Client ID is being replaced. This means that the
6812 server will query the nickname if someone needs it (client)
6815 * Sort the ID Cache in client library when the ID Cache data
6816 has changed (needs sorting).
6818 * Do not allow for SILC client to create several connections to
6819 several servers. The client does not support windows right now
6820 and generating multiple connections causes weird behaviour.
6822 Irssi-silc client does support windows and can handle several
6823 connections without problems, see: www.irssi.org and SILC plugin.
6825 * Fixed some places where client was added to the IDList. The
6826 rule of thumb is following (in order to get everything right):
6827 If the client is directly connected local client then the
6828 `connection' argument must be set and `router' argument must be
6829 NULL to silc_idlist_add_client function. If the client is not
6830 directly connected client then the `router' argument must
6831 bet set and the `connection' argument must be NULL to the
6832 silc_idlist_add_client function.
6834 * The funtion silc_server_packet_send_local_channel actually did
6835 not check whether the client was locally connected or not. It
6836 does that now. Fixed a bug related to LEAVE command.
6838 * Fixed Remove Channel User payload parsing bug in server's
6839 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6841 * The server's silc_server_save_channel_key now checks also the
6842 global ID list for the channel as it might not be in the local
6843 list. Fixed a bug related to LEAVE command.
6845 * Is this the end of the [<unknown>] buglet that has been lurking
6846 around for a long time? A little for loop fix in server's
6847 silc_server_command_whois_parse that is used by both IDENTIFY
6848 and WHOIS command. At least, this was a clear bug and a cause
6849 of one type of [<unknown>] buglet.
6851 * WHOIS and IDENTIFY commands call the function
6852 silc_server_command_[whois/identify]_check function even if
6853 we are not router server.
6855 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Added --with-gmp configuration option. If set the GMP
6858 is always compiled in the SILC source tree. If not set then
6859 it is checked whether the system has the GMP3 installed. If
6860 it has then the GMP won't be compiled (the system's headers
6861 and library is used), if it doesn't have it then the GMP is
6862 compiled in the SILC source tree.
6864 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Changed RSA private exponent generation to what PKCS #1
6867 suggests. We try to find the smallest possible d by doing
6868 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6869 not security fix but optimization.
6871 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Added new config entry [Identity] to fork the server and run
6874 it as specific user and group. A patch from Bostik.
6876 * Imported Dotconf configuration library into lib/dotconf.
6877 This will be used to create the SILC configuration files later.
6878 It will appear in the distsribution after this commit.
6880 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * A big code auditing weekend happening. Auditing code for
6883 obvious mistakes, bugs and errors. Also, removing any code
6886 Removed files for being obsolete:
6888 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6889 inline in the file lib/silcutil/silcbuffer.h)
6891 o lib/silcutil/silcbufutil.c (the header has inline versions)
6893 Changed code to fix possible error conditions:
6895 o The buffer formatting routines now check that the destination
6896 buffer really has enough space to add the data. This applies for
6897 both buffer formatting and unformatting
6898 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6899 unformatting was changed to accomodate following rules:
6900 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6901 sent to the function while XXX_*STRING will not allocate or copy
6902 the data into the buffer. Instead it sets the pointer from the
6903 buffer into the pointer sent as argument (XXX_*STRING used to
6904 require that the pointer must be allocated already). This change
6905 makes this whole thing a bit more consistent and more optimized
6906 (note that the data returned in the unformatting with XXX_*STRING
6907 must not be freed now). The routines return now -1 on error.
6909 o Tried to find all code that use buffer_format and buffer_unformat
6910 and added return value checking to prevent formatting and
6911 especially unformatting errors and possible subsequent fatal
6914 o Changed ske->x and ske->KEY to mallocated pointers in
6915 lib/silcske/silcske.h. Fixed possible data and memory leak.
6917 o Added return value checking to all *_parse* functions. Fixed
6918 many memory leaks as well.
6920 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6921 so that buffer overflows would not happen. All code now also
6922 checks the return value as it can fail.
6924 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added reconnection support to server if the normal server looses
6927 its connection to the router (for example if router is rebooted).
6928 The server performs normal reconnection strategy implemented
6929 to the server. Affected file silcd/server.c.
6931 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Added new packet type SILC_PACKET_SET_MODE that is used to
6934 distribute the information about changed modes (for clients,
6935 channels and clients channel modes) to all routers in the
6936 network. Updated the protocol specification accordingly.
6938 Added functions into silcd/packet_send.c and
6939 silcd/packet_receive.c: silc_server_send_set_mode,
6940 silc_server_set_mode.
6942 Added new files silcmode.[ch] into lib/silccore that implements
6943 the encoding and decoding of Set Mode Payload. Added new type
6944 SilcSetModePayload. Moved the definitions of different modes
6945 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6947 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * Oops, a little mistake in server's connection authentication
6950 protocol. The protocol is not ended with FAILURE but with
6951 SUCCESS if the authentication is Ok. :) Affected file is
6954 * Implemented NICK_CHANGE notify handling in server in the file
6955 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6956 the local clients on the channel. After the changing nickname
6957 in router environment snhould work and the [<unknown>] nickname
6958 should appear no more.
6960 The silc_server_replace_id function that receives the Replace ID
6961 payload now sends the NICK_CHANGE notify type also in the file
6962 silcd/packet_receive.c
6964 * Changed WHOIS and IDENTIFY command to support the maximum amount
6965 of arguments defined in protocol specs (3328 arguments). This
6966 fixed a bug that caused problems when there were more than three
6969 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Added extra parameter, command identifier, to the
6972 silc_client_send_command so that explicit command identifier
6975 Changed that ID list routines uses specific command identifier
6976 when sending WHOIS/IDENTIFY requests to the server so that they
6977 can be identified when the reply comes back.
6979 Affected files lib/silcclient/command.[ch],
6980 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6982 * Added `sender' argument to silc_server_packet_send_to_channel
6983 to indicaet the sender who originally sent the packet to us
6984 that we are now re-sending. Ignored if NULL. Affected file
6985 silcd/packet_send.[ch].
6987 * Added some server statistics support in silcd/server_internal.h
6988 SilcServerStatistics structure and around the server code. Also
6989 send some nice statistics information when client is connecting
6992 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Fixed channel ID decoding in server's JOIN command reply in
6995 silcd/command_reply.c
6997 * Fixed braodcasting of replace ID payload to not to send it if
6998 we are standalone server in silcd/packet_receive.c.
7000 * Fixed all channel message sending routines to not to send
7001 packets to clients that has router set, since they are routed
7002 separately in the same function earlier. Affects file
7003 silcd/packet_send.c and all channel packet sending functions.
7005 * In USERS reply, res_argv[i] are not allocated, the table
7006 is allocated. Thus changed that free the table, not its
7009 * In server's whois_check and identify_check if the client is
7010 locally connected do not send any WHOIS commands - they are not
7013 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * Fixed some minor bugs in client when sending WHOIS command. The
7016 arguments was in wrong order.
7018 * Removed statis function add_to_channel from server in
7019 silcd/command.c that was previously used with the joining but
7022 * Tested USERS command in router environment successfully with two
7023 routers, two servers and two clients.
7025 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Reorganized the USERS command and command reply in client library
7028 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7029 When the command is given by user we register a pending command
7030 callback that will reprocess the command after the reply has been
7031 received from the server. When reprocessing the packet we then
7032 display the information. Thus, the USERS information is displayed
7033 now in the command callback instead of in the command reply
7034 callback. The processing of the command is same as previously
7035 when server has sent the command reply in the JOINing process.
7037 * Added to USERS command in silcd/command_reply.c to join the client,
7038 we didn't use to know about, to the channel after we've created
7039 a client entry for it. Also, for clienet we did know already still
7040 check whether it is on the channel or not and add it if not.
7042 * Removed silc_server_command_join_notify as the function and its
7045 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7047 * Changed the client's pending command handling to the same as the
7048 server's pending command handling. It is also now possible to
7049 execute command reply functions from other command reply
7050 function as the function callbacks for commands and command
7051 replies are one and same. The pending commands are not static
7052 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7053 in client connection context. Thus, pending commands are server
7054 connection specific as it is convenient.
7056 Changed the function silc_client_command_pending and
7057 silc_client_command_pending_del and added new function
7058 silc_client_command_pending_check. Removed the
7059 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7062 * Added cmd_ident, current command identifier, to the client
7063 connection context in lib/silcclient/client.h to keep track on
7064 command identifiers used in command sending. Client's command reply
7065 function handling now supports the mandatory command identifiers.
7067 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7068 funtions in client to fully support pending command callbacks.
7070 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7071 as one of the arguments to the application in the command reply
7074 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7075 before first releasing SILC but came back. Now it is removed again
7076 and should come back nomore. The FORWARDED flag was used only
7077 by the JOINing procedure by forwarding the command packet to router.
7078 Now, the JOINing procedure has been changed to more generic (due
7079 to various router environment issues) and FORWARDED is not needed
7080 anymore for anything. The protocol specification is yet to be
7083 Now, removed silc_server_packet_forward from server and the flag
7084 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7086 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Renamed NAMES command to USERS command. The NAMES was named that
7089 due to historical reasons. Now it is renamed. Also, rewrote
7090 parts of the USERS command. The nickname list is not sent anymore
7091 by the server. Only Client ID and mode lists are sent in the USERS
7092 command. Changed this also to the protocol specification.
7094 The client now resolves the names and stuff after it receives
7095 the USERS list from the server when joining to the channel.
7097 * WHOIS and IDENTIFY commands has been changed to support multiple
7098 Client ID's per command. One can now search for multiple users
7099 in the network by sending only one WHOIS or IDENTIFY command.
7100 Changed the code and the protocol specifications.
7102 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7103 uses silc_server_command_whois_parse to parse the request. */
7105 * If normal server, do not parse the WHOIS and IDENTIFY requests
7106 before sending it to the router. Saves some time.
7108 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7110 * Fixed JOIN command on client library. Wrong number of arguments
7111 used to crash the client.
7113 * Added silc_server_channel_has_global function to check whether
7114 channel has global users or not.
7116 * Added silc_server_channel_has_local function to check whether channel
7117 has locally connected clients on the channel.
7119 * The silc_server_remove_from_one_channel now checks whether the
7120 channel has global users or not after given client was removed from
7121 the channel. It also checks whether the channel has local clients
7122 on the channel anymore. If it does not have then the channel entry
7123 is removed as it is not needed anymore.
7125 * The silc_server_notify now checks on JOIN notify whether the joining
7126 client is one of locally connected or global. If it is global then
7127 the channel has now global users on the channel and that is marked
7128 to the channel entry. Also, it now saves the global client to
7129 global list who is joining and JOINs it to the channel. This is
7130 for normal server, that is.
7132 Changed silc_server_send_notify_on_channel,
7133 silc_server_packet_relay_to_channel and
7134 silc_server_packet_send_to_channel check if we are normal server
7135 and client has router set (ie. global client) do not send the
7136 message to that client, as it is already routed to our router.
7138 * Implemented LEAVE notify type handling in silc_server_notify
7141 * Tested LEAVE command in router environment successfully. Tested
7142 with two routers, two servers and two clients.
7146 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7148 * Implemented SIGNOFF notify type handling in silc_server_notify
7151 * silc_server_remove_id now removes the client entry from all channels
7152 it has joined and thusly sends SIGNOFF notify type.
7154 * Rewrote the NAMES list generation in server by removing two excess
7155 loops. The lists are created now inside one loop.
7157 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * silc_server_remove_channel_user checks now also global list
7160 for channel and client.
7162 * silc_server_new_channel_user checks now both local and global
7163 list for channel and client. Fixed a bug in client id decoding.
7164 Used to decode wrong buffer.
7166 * silc_server_channel_message checks now both local and global
7167 list for channel entry.
7169 * Tested channel joining (hence JOIN) in router environment
7170 successfully. Tested with two routers, two servers and two
7173 * Tested channel message sending in router environment successfully.
7175 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added silc_server_save_channel_key into server.[ch] to save the
7178 received channel key in Channel Key payload processing. It is
7179 also used in JOIN command reply handling.
7181 Equivalent function silc_client_save_channel_key added into
7182 client.[ch] into client library.
7184 * Changed JOIN command reply to send information whether the channel
7185 was created or not (is existing already) and the channel key
7186 payload. Changed protocol specs accordingly.
7188 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7189 the request was sent by ID and not by nickname. Crashed on
7192 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7195 now correctly save the received data.
7197 * silc_server_free_sock_user_data now notifies routers in the
7198 network about entities leaving the network.
7200 At the same time implemented functions silc_server_remove_id
7201 and silc_server_send_remove_id to receive and send REMOVE_ID
7202 packets. The packet is used to notify routers in the network
7203 about leaving entities. The ID removed will become invalid in
7206 * Added function silc_idlist_del_server into server. Removes and
7207 free's server entry from ID list.
7209 * silc_server_private_message function now checks, if we are router,
7210 that the destination ID really is valid ID, naturally.
7212 * In router when NEW_ID packet is received (for new client) the
7213 hash of the Client ID is saved in the ID Cache but the
7214 client->nickname is set to NULL, instead of putting the hash
7217 IDENTIFY command now also checks that client->nickname must be
7218 valid. If it is not if will request the data from the server who
7219 owns the client. Added new function
7220 silc_server_command_identify_check.
7222 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7223 to set the command to already allocated Command Payload.
7225 * Tested private message sending in router environment with two
7226 routers, two servers and two clients. Fixed minor bugs and now
7229 * Fixed segfault from client's NAMES command. Used to crash if
7232 * Forwarded packets must not be routed even if it is not destined
7233 to the receiver. Changed server code comply with this.
7235 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Added `require_reverse_mapping' boolean value to ServerParams
7238 structure. If TRUE (not default) the server will require that
7239 the connecting host has fully qualified domain name.
7241 If the reverse mapping is not required and hostname could not be
7242 found the IP address is used as hostname.
7244 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Implemented version string checking to both client and server.
7247 The check is incomplete currently due to the abnormal version
7248 strings used in development version of SILC.
7250 * Changed all command functions in server to use the new
7253 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Changed char *data to unsigned char *data in ID Cache system to
7256 support binary data as ID Cache data. Changed code to support
7257 binary data in lib/silccore/idcache.c.
7259 * Renamed silc_server_packet_relay_command_reply to
7260 silc_server_command_reply as it is normal packet receiving
7261 function. Rewrote the function to accept command replys for
7262 servers and not only for clients.
7264 * Mark remote router always as registered server if we are connecting
7265 to it. Otherwise, commands sent by the router to us are ignored.
7267 * All ID List find routines now returns the ID Cache Entry pointer
7268 as well if requested.
7270 * WHOIS command works now in router environment, tested with two
7271 routers, two servers and two clients.
7273 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7274 in router environment (as it is almost equivalent to WHOIS) but
7275 hasn't been tested thoroughly. Added new functions:
7277 silc_server_command_identify_parse
7278 silc_server_command_identify_send_reply
7279 silc_server_command_identify_from_client
7280 silc_server_command_identify_from_server
7282 * Disabled route cache adding because adding two different ID's with
7283 same IP replaces the old cache entry thus giving wrong route.
7284 The entry->router->connection is always the fastest route anyway
7285 so route cache may not be needed. Of course, new routes maybe
7286 established after receiving the ID when the entry->router->connection
7287 might not be anymore the most optimal.
7289 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Add route cache for received ID for fast routing.
7293 * Added silc_server_packet_route to route received packet on router
7294 that is not destined to us.
7296 * Renamed silc_server_get_route to silc_server_route_get.
7298 * Added id_string and id_string_len fields into SilcServer to
7299 include encoded ServerID for fast comparing without excess
7300 encoding of the ID's.
7302 * Cleaned up WHOIS command on server side. Added following static
7305 silc_server_command_whois_parse
7306 silc_server_command_whois_check
7307 silc_server_command_whois_send_reply
7308 silc_server_command_whois_from_client
7309 silc_server_command_whois_from_server
7311 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7312 arguments in command replies. All command functions should be
7313 updated to use this macro.
7315 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7317 * Minor typo fixes on command reply handling on server.
7319 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added silc_server_command_add_to_channel internal routine to add
7322 the client to the channel after router has created the channel and
7323 sent command reply to the server.
7325 * Added generic silc_server_send_command to send any command from
7328 * Use static buffer with ID rendering instead of duplicating data.
7330 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7332 * Fixed a channel user mode bug when joining to a channel server gave
7333 everybody channel founder rights, oops.
7335 * We mark ourselves as the router of the incoming server connection
7336 if we are router ourselves. This way we can check in some packet
7337 sending functions whether it is locally connected server. For
7338 incoming router connections we put NULL.
7340 * For router sending packets locally means now always sending the
7341 packet cell wide; to local clients and local servers. For normal
7342 server sending packet locally means sending it to only local
7345 * Fixed the JOIN command to really work in router environment. If the
7346 channel is created it is always created by the router. Router is
7347 also responsible of making the initial joining to the channel,
7348 sending JOIN notify to the sending server and distributing
7349 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7350 does not exist server doesn't do anything else but forward the
7351 command to the router which performs everything.
7353 * Added silc_server_send_channel_key function to send the Channel Key
7356 * Added silc_server_create_channel_key to create new channel key. The
7357 channel key is now re-generated everytime someone joins or leaves
7358 a channel, as protocol dictates. Note: channel->key_len is the
7361 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7364 packet_receive.[ch] to separate packet sending and receiving
7365 routines. The server.[ch] now includes everything else including
7366 actual packet processing (writing and reading data) and other
7369 Renamed silc_server_private_message_send_internal to
7370 silc_server_send_private_message. The routine is still though
7371 used only to relay private messages as server does not send
7372 private messages itself.
7374 Renamed silc_server_new_channel to silc_server_create_new_channel
7375 and added new function sicl_server_new_channel that handles the
7376 incoming New Channel packet. Added also new sending function
7377 silc_server_send_new_channel to send New Channel Payload.
7379 * Added new function silc_server_notify to process incoming notify
7380 packet to the server/router. Server may then relay the notify
7381 to clients if needed.
7383 * Added new function silc_server_new_channel_user to process incoming
7384 New Channel User packet. Router will redistribute the packet and
7385 send JOIN notify to its local clients and locally connected servers
7386 if needed. Normal server will send JOIN notify to its local client
7387 on same channel when received this packet. Added also corresponding
7388 sending function silc_server_send_new_channel_user to sent the
7391 * Added boolean route argument to send_notif_to_channel and
7392 packet_send_to_channel functions to attempt to route the packet
7393 if it is TRUE and send only locally if it is FALSE.
7395 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * silc_server_replace_id now broadcasts the received replace ID
7398 packet if it is not broadcast packet already. The router must
7399 broadcast to inform other routers about changed ID.
7401 * Added backpointer to server's router into SilcServer context in
7402 silcd/server_internal.h.
7404 * Fixed silc_server_packet_broadcast to send correct broadcast
7407 * The channel key is now distributed to the local client as soon
7408 as it is received from the router (in router environment) so that
7409 no other packet may be sent for the channel until client has
7412 * silc_server_remove_channel_user now broadcasts the received
7413 Remove Channel User packet if it is not broadcast packet already.
7414 The router must broadcast to inform other routers about removed
7417 * Added users field into SilcPacketContext that is a reference count
7418 of the context. One can increase the reference count by calling
7419 silc_packet_context_dup which is now changed to just increase the
7420 reference count instead of duplicating the data. The reference
7421 count is decresed by calling silc_packet_context_free that will
7422 free the data after the reference count hits zero.
7424 For now on the packet context and everything allocated into it
7425 (including the raw packet from network) must be freed by calling
7426 the new silc_packet_context_free function. Added also new function
7427 silc_packet_context_alloc that must be used now to allocate the
7428 context. This also means that if a routine is asynchronous from
7429 silc_[client/server]_packet_parse_type the packet context must
7430 be duplicated by calling silc_packet_context_dup. Otherwise it
7431 gets free'd after silc_[client/server]_packet_parse_type returns.
7432 Also, one must remember that if packet is duplicated then its
7433 reference count must be decresed by calling the free function as
7434 many times as it was duplicated.
7436 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7437 from both client and server.
7439 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7441 * Made joining to a channel working in router environment.
7443 * Cleaned up JOIN command on server side and create function
7444 silc_server_command_join_channel internal routine to make the
7447 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Changed silc_command_pending list to SilcDList. Also, added
7450 `ident' field to SilcServerCommandPending structure to identify
7451 the reply and to call correct callback.
7453 Added silc_server_command_pending_check function to replace the
7454 corresnponding macro. The silc_command_pending list is not
7457 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7458 to set identifier to previously allocated Command Payload. It
7459 is used to set identifier for command when resending Command
7462 * Added silc_command_payload_encode_payload to encode Command
7463 Payload buffer from SilcCommandPayload structure.
7465 * Added silc_argument_payload_encode_payload to encode Argument
7466 payload buffer from SilcArgumentPayload structure.
7468 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7470 * Changed WHOIS command to support router connection on server side.
7471 The whois request is always sent to router unless the server is
7472 standalone server. After server has received the reply from the
7473 router will it send the reply to the client.
7475 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7476 broadcast received broadcast packet. The function is used only
7477 by router. The broadcast packet is always sent to the router's
7480 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7481 render given ID to printable string, for log files for example.
7483 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Made basic router to router connections working. At least they
7486 can now connect to each other but nothing really works the way
7487 they are supposed - yet.
7489 * Added new initiator token to RouterConnection configuration
7490 file in silcd/serverconfig.[ch]. It is used to tell whether we
7491 are the initiator to the remote router or whether we'll expect
7492 the other end to connect.
7494 * Moved registering of listener task to silc_server_init, hence
7495 the server starts listenning as soon as it is run, even if it
7496 does not have connections to other routers. Let's see how well
7499 * Changed default connection retry timeouts for more suitable in
7502 * Removed cipher and such arguments from silc_idlist_add_client
7503 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7504 Added new function silc_idlist_add_data to add the keys and stuff
7507 * Added SilcIDListData structure and added it to SilcClientEntry
7508 and SilcServerEntry as their first field in the structure. This
7509 way we can explicitly cast the ID entries to the SilcIDListData
7510 structure and get common data for the entries. In past, we had
7511 to first check what type of connection it is and then cast it to
7512 correct ID entry type. Now, we can directly cast the opaque
7513 pointer to the SilcIDListData (no matter what ID entry it actually
7514 is) and get the data needed.
7516 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7519 in some circumstances even if threre were timeout tasks, though not
7520 IO tasks, but tasks anyway. Now fixed.
7522 * Defined SilcServerConnection structure to hold connection specific
7523 stuff about directly connected servers and routers. The definition
7524 is currently in silcd/server_internal.h. I thought about having
7525 a bit more important role fro this struct but for now it is used
7526 only when connecting to other server (or router actually).
7528 * Added connecting retry support in server when connecting to
7529 router(s). The retry feature implement exponential backoff
7530 algorithm. Also, added SilcServerParams structure to hold default
7531 parameters for server. For now, it include these retry settings
7532 and are hard coded. After server is moded to be as Silc Server
7533 Library this structure will be more important.
7535 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Changed client librarys channel->clients table to SilcList and
7538 changed code accordingly.
7540 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Changed client's channel table to SilcList and changed code
7543 accordingly. Also changed SilcChannelClientEntry to include back-
7544 pointer to the channel so that client entry can use that structure
7545 as list as well and we have fast cross-reference to the channel.
7546 This change dramatically decreased the complexity of channel
7547 handling with client entry and vice versa (removed one extra
7548 loop when searching for channel entry from many functions).
7550 * Changed server->sim from table to SilcDList and changed code
7553 * NAMES command can now be used from user interface. It will show
7554 the user list on the channel, neatly.
7556 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7557 Code now saves realname of the user if it becomes available.
7559 * Renamed configure.in to configure.in.pre and made ./prepare
7560 script to automatically add correct version string to
7561 configure.in which it creates from configure.in.pre.
7563 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * NAMES command reply now shows users mode with the nickname when
7568 * Moved silc_client_ch[u]mode[_char] functions from
7569 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7570 place sucks, they are utility functions and should be in some
7573 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7575 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7578 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Added TRQ (efficient deque and list library) into lib/trq. This is
7583 a very good list library that is currently used in the SILC. Defined
7584 SilcList API over the library because I didn't like the API very
7585 much. See lib/trq/silclist.h for the API and examples of how to
7586 use the API. Fixed various places in the code to use the new
7587 SilcList API. The SilcList is meant for lists that has a structure
7588 already defined as a list. It is not suitable to add just some
7589 context to the list (in TRQ, the context is the list actually).
7591 So, I defined SilcDList that can be used for the purpose where
7592 predefined list structure does not exit. This can be used as
7593 such list. Now some context just can be added to the SilcDList.
7594 Currently this list is not used in the SILC just yet, though there
7595 are a lot places where this can replace dynamically allocated
7596 tables and I will fix these places, later, to use SilcDList.
7597 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7598 and use TRQ internally).
7600 Also fixed some annoying warning messages that the original TRQ
7601 code generated. Also minor changes to TRQ's Makefile.in.
7603 * Added support for querying by Client ID to both WHOIS and
7604 IDENTIFY commands into server, as required by the protocol.
7606 * Removed method function pointers from SilcBuffer structure. They
7607 weren't used to anything and just increased the context size for
7608 no good reason. This change also made silc_buffer_alloc and
7609 silc_buffer_free functions inline functions.
7611 * Disabled command flooding detection support until it's fixed so
7612 that it accepts commands in but does not execute them more than once
7615 * Added silc_net_localhost(), to return local hostname, into
7616 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7617 that must be initialized before calling silc_client_init.
7619 * Added new function: silc_server_send_notify_on_channels to send
7620 notify messages to all channels client has joined. It is assured
7621 that the message is sent only once per client.
7623 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7624 lib/silcutil/silcutil.[ch] as silc_format function. The new
7625 function is generic and is used by server as well, not only by
7626 the logging routines.
7628 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7629 the provided version string was not acceptable. Added new function:
7630 silc_ske_check_version into lib/silcske/silcske.h. The function
7631 must be implemented by the application (client or server) and it
7632 does not reside in the SKE library. The function checks the version
7633 string remote end sent.
7635 * Added back pointers (to opaque context and to SilcSocketConnection)
7636 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7638 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7639 duplicate packet context structure.
7641 * Changed `notify' client operation to send same arguments as client
7642 receives from server except for ID's. ID's are mapped to correct
7643 ID entry and that is returned. Also, if channel entry is not sent
7644 by server but the notify is for channel the channel entry is sent
7645 to application (otherwise application doesn't know that it is for
7646 channel (library gets it from packet's Destination ID)).
7648 * Added silc_client_remove_from_channels into client library to
7649 remove a client from all channels it has joined to. Used when
7650 received SIGNOFF notify from server. Added also new function
7651 silc_client_replace_from_channels to replace old ID entry with
7652 new ID entry on all channels. Used when received NICK_CHANGE
7655 * Fixed ID Cache list handling in silc_idlist_get_client in
7656 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7657 to get (or query) client by ID.
7659 * Updated TODO list.
7661 * Added connection authentication status message defined by the
7662 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7663 support for these into the code in client and server side.
7665 * Added generic function silc_client_send_command to send any command
7666 with variable argument list. Application should use this function
7667 to send commands if the command functions provided by the library
7668 does not suite for the application's user interface needs.
7670 * Added new `failure' client operation. Application is notified about
7671 received failure packet if client is executing a protocol. In this
7672 case the protocol's execution has failed.
7674 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7675 is required by the protocol.
7677 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7678 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7681 * Added status flag to SilcSKE object to indicate realtime status
7682 of the SKE protocol.
7684 * Application receives now exactly same command reply arguments as
7685 the library receives from server. However, if ID is received the
7686 corresponding ID entry is returned to the application (eg. Client
7687 ID is mapped to correct SilcClientEntry entry and that is returned).
7688 Changed command_reply client operation due to this change.
7690 * Changed all ID's in commands and in command replys as ID Payloads.
7691 Change affected both client and server side codes.
7693 All ID's sent in SILC network (with execption of ID's in SILC
7694 Packet header) are sent in ID Payload to support variable length
7697 * Server now notifies nick changes and notifies all clients on
7698 the channels about the new nickname (about the new Client ID,
7701 * Implemented CMODE command to change channel modes. Supports all
7702 channel modes defined by the protocol specs except ban and invite
7703 lists. (Also, private channel key mode is supported but support for
7704 setting private channel key in client is missing, thus, this mode
7705 has no effect on client side (except that server requires that the
7706 client uses private channel key and normal channel traffic does not
7709 Also, invite mode works per se, but INVITE command does not work
7710 yet correctly, so you can set channel as invite only channel but
7711 inviting clients to the channel does not work (it is yet to be
7712 thought what's the best way to do it).
7714 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7715 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7716 Implemented CUMODE command to change user's mode on the channel.
7717 Supports all modes defined by the protocol specs.
7719 * Added NAMES command reply to return users modes on the channel.
7721 * Removed unnecessary and slow ciphers from lib/silccrypt.
7723 * Set SO_KEEPALIVE option to connection sockets by default.
7725 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7727 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7728 redefined the Notify Payload into protocol specs.
7730 * Added silc_id_payload_parse_id to get ID directly from raw
7733 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7736 accept searching by Client ID as well.
7738 * Added support for LEAVE and SIGNOFF notify types in client library.
7740 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7741 to parse ID Payload from raw data.
7743 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Added flags parameter into silc_ske_assemble_security_properties
7746 function in lib/silcske/silcske.[ch].
7748 * Changed notify client operation to fit better for notify messages
7749 sent by server. The notify payload received from server is now
7750 passed to the application (after parsing it to SilcNotifyPayload).
7751 It is application's responsibility to retrieve the arguments
7752 from the payload and show the message the way it wants. The message
7753 sent by server is implementation specific.
7755 * Changed public keys to comply with the protocol specification.
7756 Old public keys are not supported anymore and are not compatible.
7758 * Removed nickname from Channel Payload as the latest draft removed
7759 it. The client must resolve the nickname from the NAMES command
7760 reply received when it joined the channel.
7762 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7764 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7766 * Fixed some errors in protocol specification drafts.
7768 * Created lib/silccore/silcnotify.c to implement Notify Payload
7769 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7770 generic payloads described by protocol specifications. The file
7771 includes implementations for ID Payload and Argument Payload.
7773 * Changed Command Payload implementation to use the new Argument
7774 Payload. Changed command_xxxx_payload to command_payload_xxxx
7775 to comply with SILC coding conventions.
7777 * Added suppport for Argument Payload handling in Notify Payload
7778 implementation as protocol requires it. Added the new support
7779 into server and client lib as well.
7781 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7783 * Added support for multiple nicknames on same channel. [n] is
7784 added locally to the nickname if there are more than one same
7785 nicknames on the channel.
7787 * Server now sends all nicknames that matched WHOIS request.
7788 Client also shows the list received from server.
7790 * Added TOPIC command to client side. User can now set and show
7791 current topic on channel.
7793 * Added MOTD command to client and server. Also, server sends the
7794 motd when client connects to the server.
7796 * Changed version strings to comply ISO 8601.
7798 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7800 * Fixed protocol error handling in client library. It should now
7801 cope even if the SKE fails for some reason.
7803 * Made new protocol specification drafts for submitting to IETF.
7805 * Implemented TOPIC command to server in silcd/command.c.
7807 * Added two new notify types into lib/silccore/silcnotify.h:
7808 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7809 notify nickname change and topic setting/change on a channel.
7811 * API change of command_reply operation in client library. The
7812 application gets now the status type received from server as well.
7814 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7816 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7818 * Cras fixed and optimized the packet handling even further and
7819 it should work now. Minor change to the prototype of function
7820 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7822 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7824 * Added new function into lib/silcutil/silcschedule.[ch]:
7825 silc_schedule_with_fd to select() a specified fd. The function
7826 returns after timeout expires or data arrives or goes. The
7827 function is used by packet routines to wait that all data is
7828 received from network.
7830 * Fixed data reading from network in lib/silccore/silcpacket.c.
7831 The code now assures that all data is read from the fd and then
7832 continues packet processing. This was a bug fix since the code
7833 used to drop some data in some circumstances.
7835 * Added new function into lib/silcclient/client.[ch]:
7836 silc_client_start_key_exchange to start key exchange after
7837 connection has been established to server. The code internally
7838 now uses this funtion but its main purpose was to provide it
7839 for applications that perform their own connecting. After
7840 application has created a connection it merely calls this
7841 function to start the key exchange between client and server.
7842 The library takes care of everything else after that.
7844 Updated also lib/silcclient/README to explain the usage of
7847 * Do not send to application information that connection has
7848 been established. Application gets notified it by connect
7851 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7853 * Applied cras's patch to add silc_schedule_one function. The
7854 function runs scheduler once and returns.
7856 * Fixed the scheduler after cras messed it up. The timeout
7857 handling works now as it's supposed to work.
7859 * Added into lib/silccore/ silcnotify.h to include notify
7860 message types support. Changed silc_server_send_notify*
7861 functions, in server.[ch], to support those new notify types.
7862 Added the support for the notify types into client library,
7863 as well. Added new notify client operation into ops.h in
7866 * Changed silc_server_packet_send_to_channel to send normal
7867 packets instead of just channel message packets. The function
7868 is now used to send the notify packets to channels. It is not
7869 used to send channel message packets anymore, as server never
7872 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7873 va_arg()s as it seems to require it nowadays. I guess, if SILC
7874 is compiled with older va_arg() the new code should work anyway.
7876 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7878 * Splitted core library. Core library (lib/silccore) includes
7879 now only SILC protocol specific core (and common) components.
7880 Created new utility library (lib/silcutil) that includes more
7881 generic purpose stuff. The stuff for util library was taken
7882 from the old core library. This was minor and easy split.
7884 * Created SILC Client Library (lib/silcclient) that includes
7885 implementation of the SILC client without user interface. This
7886 was major move from silc/ directory. The code has been changed
7887 so that it is transparent towards the user interface. The
7888 silc/ directory includes now the same user interface as before
7889 and it uses the new client library. Read lib/silcclient/README.
7890 Basicly, the client library performs everything else related
7891 to SILC except user interface handling. Also, configuration
7892 files are considered to be part of user interface and library
7893 does not handle them.
7895 This change also changed a lot of structures, function naming etc.
7896 Most important change was that SilcClientWindow object was
7897 renamed to SilcClientConnection in the client library. Created
7898 also new file lib/silcclient/ops.h. Also added new files
7899 silc/local_command.[ch] and silc/client_ops.[ch].
7901 All these changes were made to make it easier for user interface
7902 designers to create what ever user interface for the SILC client
7905 It is also expected that the server will be moved to lib
7906 directory as well and SILC Server Library will be created;
7907 sometimes in the future.
7909 * Removed Local commands from lib/silccore/silccommand.h as
7910 they are application specific and new client library does not
7911 handle any of those anymore.
7913 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7914 old client implementation in silc/.
7916 * Added support for callback functions in SILC_LOG_* macros.
7917 Application can now set its own callbacks that will be called
7918 instead of using the default functions that will always print
7919 the debug messages to stderr (or stdout). Also, debugging can
7920 now be disabled by setting silc_debug to FALSE and re-enabled by
7921 setting it to TRUE. Note, that logging will still work even
7922 if debugging is disabled.
7924 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7925 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7926 silc_log_reset_debug_callbacks.
7928 * To enable debugging in silc client one must give now -d
7929 option on command line.
7931 * Changed silc_schedule_init to automatically allocate task queues
7932 if they are not allocated before calling it.
7934 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7936 * Added GMP 3.1 into math library.
7938 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7940 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7941 a channel in SILC network. The packet is used by servers and
7942 routers to notify other routers that user has left a channel.
7943 This little feature was missing until now. Added the feature
7944 to protocol specification as well.
7946 Added functions: silc_server_send_remove_channel_user and
7947 silc_server_remove_channel_user into server.[ch].
7949 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7950 lib/silccore/silcpacket.h. However, they are not implemented
7953 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7955 * Fixed joining to a channel and sending channel messages
7956 between server and router. The channel message sending should
7957 now work inside a cell.
7959 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7961 * Fixed the private message sending between server and router.
7962 The private message sending should now work inside a cell.
7964 * Added silc_server_replace_id into server.[ch] to replace
7965 existing ID in the SILC network.
7967 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7968 and silc_idlist_replace_server_id into idlist.[ch] in server.
7970 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7972 * Fixed the server to server connections. Server can again now
7973 connect to router. Router to router connections probably does
7976 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Added dynamic protocol registering support. Now protocols can
7979 registered and unregistered on the fly. Patch by cras.
7981 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7983 * Added lib/contrib directory to hold routines that some platforms
7984 don't have but are needed by SILC.
7986 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7987 into lin/contrib to provide getopt() and getopt_long() for
7988 those who don't have it.
7990 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7992 * Added AWAY command to client. When away message is set and
7993 client receives a private message packet the client automatically
7994 replies to the sender with the away message.
7996 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7997 bug seemed to be the cause of recent problems when compiling
8000 * Added version detection support to SKE protocol specification
8001 and added the new changes to the SKE implementation as well.
8002 There were other minor changes in the SKE protocol as well.
8004 Many changes in lib/silcske/silcske.[ch] and in
8005 lib/silcske/payload.[ch].
8007 * Added ^U functionality, clear input line. Patch from cras.
8009 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Mainly small bugfixes on core library. Fixed some debugging
8012 logging and buffer overflow in silclog.c.
8014 * Updated config.sub and config.guess on the distribution tree.
8016 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Added command lagging support in server. Client may execute
8019 commands now only once in two seconds.
8021 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8023 * Optimized packet reception. MAC computation and checking is now
8024 also more optimized. A lot previously duplicated code is now
8025 used as generic by both client and server.
8027 * Fixed key pair generation in clientutil.c
8029 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Added into lib/silccore/silcbufutil.[ch] new function;
8032 silc_buffer_realloc.
8034 * Moved generic packet sending/encryption functions to
8035 lib/silccore/silcpacket.[ch] from client and server. Some
8036 rewriting of the functions.
8038 * Moved all generic packet reception/decryption functions to
8039 lib/silccore/silcpacket.[ch] from client and server. The
8040 packet processing is now much cleaner in both client and server.
8041 These were major changes in both client and server.
8043 * Created many common functions in server to do packet sending.
8044 Previously code were duplicated a lot, this has been removed
8047 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8049 * Rewrote major parts of the ID cache system. Don't know
8050 whether it is better now or not but at least the API is more
8053 * Major rewrite on ID cache stuff on client because of the ID
8054 cache API changes. Added idlist.c to client.
8056 * Also major rewrite on ID cache stuff on server as well.
8057 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8058 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8059 in hand, instead they are all put into the ID cache system now.
8060 All server_idlist_* routines uses ID cache now instead of
8061 traversing its own lists (those lists does not exist anymore).
8062 SilcIDList though still exists. Also, SilcXXXEntry's are
8065 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Finally made the SKE implementation compliant to the protocol
8068 specification. All mp integers are now binary encoded as
8069 opposed being HEX encoded.
8071 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8074 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8075 functions: silc_[encode/decode]_pem. Also added function
8076 silc_encode_pem_file to PEM encode with newlines ('\n') for
8079 * SILC public keys are now encoded either PEM or binary. Same
8080 option is for private keys as well. By default private keys
8081 are binary encoded and public keys PEM encoded. Silly HEX
8082 encoding were removed.
8084 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8085 function to create fingerprints.
8087 * Fixed a bug in SHA1; does not change the original data anymore.
8089 * Partly implemented INFO command on client and server side.
8090 Fixed CLEAR command. Changes to SERVER command; show current
8091 server(s) when giving command without arguments. Added
8092 VERSION command to client.
8094 * Added check to server that unregistered connections cannot
8095 execute commands (unless it is specificly allowed).
8097 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8099 * Fixed screen refresh.
8101 * Fixed channel joining bug from client. On some circumstances
8102 client tried to join to a channel it had already joined.
8104 * Added public key verification process into client's protocol.c.
8105 The client now verifies the public key from user and saves
8106 it into ~./silc/serverkeys/ directory.
8108 Added into: clientutil.[ch]: silc_client_verify_server_key.
8110 * Changed SKE protocol's silc_ske_initiator_finish function
8111 to accept callback function that verifies the received public
8112 key. Removed old silc_ske_verify_public_key function.
8114 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8117 silc_pkcs_private_key[_data]_set.
8119 * Made the password and public authentication more cleaner in
8120 server's protocol.c.
8122 * Removed historic and obsolete protocol `channel_auth' from
8123 both client and server.
8125 * Removed wrong way of sending command status messages from
8126 server to client in server's command.c. The old way violated
8127 protocol specification.
8129 Changes to silccore/silccommand.[ch]: removed
8130 silc_command_encode_status_payload -> not needed anymore,
8131 changed silc_command_encode_payload_va to accept extra
8132 argument on variable argument list. The argument type must
8133 now be provided to the function. Also, added new function:
8134 silc_command_encode_reply_payload_va which is same as
8135 normal command_encode_payload_va except command status type
8136 is provided as extra argument.
8138 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Added ~./silc directory handling. The directory includes the
8141 public and private keys for the client.
8143 Added silc_client_check_silc_dir, silc_client_create_identifier
8144 and silc_client_load_keys.
8146 * Implemented SILC protocol compliant public key. Added public
8147 and private key saving to and loading from files.
8149 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8150 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8151 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8152 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8153 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8155 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8156 silc_pkcs_load_[public/private]_key.
8158 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8160 * Added silc_server_get_route (route.[ch]) to get connection
8161 data for the fastest route for given ID.
8163 * Implemented INVITE command on client and server. The command
8164 were re-defined in the SILC Protocol Specification and the
8165 implementation now complies with the specification.
8167 * Implemented PING command on client and server.
8169 * Implemented NAMES command on client and server. The server side
8170 supports currently only normal server not router server yet.
8171 Some changes to NAMES definition in SILC protocol specification.
8173 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8175 * Implemented LEAVE command on client and server.
8177 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8178 again. This change was made to the protocol as well. Server
8179 should not violate the protocol specification anymore.
8181 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8183 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8184 was tested. SOCKS4 was not but should work anyway.
