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

61 options to the server. Affected files silcd/serverconfig.[ch],
62 silcd/command.c and silcd/packet_receive.c.
64 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Added resolve_cmd_ident field to the SilcClientEntry structure
67 too so that if the entry is for example being resolved so
68 another command may attach to the same pending command reply
69 without requiring to resolve the same entry again. Added
70 support for adding multiple pending commands for one
71 command idenfier. Affected files lib/silcclient/command.[ch],
72 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
74 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
76 * Defined that server receives WHOIS command reply for private
77 and secret channels too. Updated protocol specs and the
78 code in server. Affected file silcd/command.c.
80 * Defined <channel user mode list> argument to WHOIS command
81 reply for returning user modes on the channels. The
82 channel list now doesn't include the user mode anymore but the
83 actual channel mode. Updated protocol specs and the code in
84 client and server. Affected files are silcd/command_reply.c,
85 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
86 and lib/silcclient/command_reply.c.
88 * Save the channels list in WHOIS command reply in normal server
89 so that WHOIS always shows joined channels also in normal
90 server and not just on router. Affected file is
91 silcd/command_reply.c.
93 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
95 * Defined that server receives USERS command reply for private
96 and secret channels too. Updated protocol specs and the
97 code in server. Affected file silcd/command.c.
99 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Changed the UMODE's mode mask argument to be optional. If
102 not provided then the command merely returns the current mode
103 mask to the client. Updated protocol specs and the server.
104 Affected file is silcd/command.c.
106 * Added SILC session detachment/resuming support. It is possible
107 to detach by closing the network connection and then re-connect
108 and resume to the old client session. Added DETACHED user
109 mode that server will set for detached client. Added new
110 packet RESUME_CLIENT which is used to perform the resuming
111 process. Added DETACH command. Updated the protocol specs,
112 core library, client and server. Protocol TODO #22. Very
113 many affected files around the tree.
115 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Changed the CMODE's mode mask argument to be optional. If
118 not provided then the command merely returns the current mode
119 mask to the client. Updated protocol specs and the server.
120 Affected file is silcd/command.c.
122 * Changed the Killer's Client ID in KILLED notify to be just
123 any ID payload since router server is allowed to kill as well.
124 Updated protocol specs, client libary and server. Affected
125 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
126 and irssi/src/silc/core/client_ops.c.
128 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Added new user modes ANONYMOUS for special anonymous servers
131 that may set the mode for client, and BLOCK_PRIVMSG which
132 client may set to block incoming private messages unless the
133 Private Message Key flag is set (using private keys to protect
134 private messages). Updated protocol specs and code in client
135 and server and core library. Protocol TODO #23. Affected
136 files are lib/silccore/silcmode.h, silcd/server.[ch],
137 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,

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

183 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
184 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
186 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Added STATS command to the protocol after all, to return
189 various statistical information about the network. It can
190 be used by clients to retrieve statistical information, and
191 servers may use it to to fetch cell and network wide
192 statistics from router. Updated the protocol specs and
193 implemented it to the server. Protocol TODO #16.
194 Affected files are lib/silccore/silccommand, silcd/command.[ch],
195 silcd/command_reply.[ch].
197 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
199 * The LIST command reply in client libary now adds new channel
200 entry if the returned channel doesn't exist yet in cache,
201 and returns the channel entry to the application in the
202 command_reply client operation. Affected file is
203 lib/silcclient/command_reply.c.
205 * Changed the channel message payload's MAC generation to
206 include the IV in the MAC as well. This way all relevant
207 parts of the channel message payload are authenticated also
208 with the channel message MAC (and not only by packet MAC).
209 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
210 Affected file is lib/silccore/silcchannel.c.
212 * Fixed the SKE to save the remote version, since the
213 silc_ske_parse_version mistakenly checked wrong version,
214 after it replaced the start payload. Affected files are
215 lib/silcske/silcske.[ch].
217 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
220 string utility functions. Added there also new functions
221 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
222 Affected files lib/silcutil/silcstrutil.[ch].
224 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
225 files are lib/silcutil/silcstrutil.[ch].
227 * Defined that the security property fields in SKE SHOULD be
228 UTF-8 encoded, defined that version string MUST be US-ASCII
229 encoded, defined that passphrases sent in connection
230 authentication protocol MUST be UTF-8 encoded. Implemented
231 these to the client and server. Defined also that other
232 passphrases sent in the protocol MUST be UTF-8 encoded.
233 Affected files are lib/silcske/silcske.c,
234 lib/silcclient/protocol.c, silcd/protocol.c,
235 silcd/serverconfig.c, and lib/silccore/silcauth.c.
237 * Changed the silc_client_close_connection interface to not
238 need the SilcSocketConnection which should not be visible
239 to application. Affected files are lib/silcclient/client.c
240 and lib/silcclient/silcclient.h.
242 * Rewrote the text for Private Message Key Payload in the
243 protocol specification. Protocol TODO #11.
245 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
247 * Upgraded the protocol version to 1.1, updated protocol specs
250 * Added the nickname as new argument to NICK_CHANGE notify and
251 added it to protocol specs and implemented it to client and
252 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
253 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
254 lib/silcclient/client_notify.c.

260 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
261 The killer's client entry is now returned to application in
262 the `notify' client operation.
264 * Fixed the Max Argument fields that had too large value set
265 in the protocol specs. Protocol TODO #14.
267 * Added the LEAVE command reply to return the ID of parted
268 channel. Updated protocol specs and implemented it to the
269 client and server. Protocol TODO #15. Affected files are
270 silcd/command.c, lib/silcclient/command_reply.c. The channel
271 entry is now returned to application in the `command_reply'
274 * Rewrote the version SKE version checking in client libary
275 and in server to use the silc_parse_version_string. Affected
276 files are lib/silcclient/protocol.c, silcd/protocol.c.
278 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
279 commands that was missing it, and updated protocol specs and
280 the server implementation. Protocol TODO #10. The affected
281 file is silcd/command.c.
283 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
284 generic reply to a generic request (REQUEST flag), and
285 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
286 way. A draft-riikonen-silc-flags-payloads-00.txt is written
287 to define the payload for DATA flag. Added the flags to
288 the implementation. Protocol TODO #9. Affected file is
289 lib/silccore/silcchannel.h.
291 Changed the client library to return the message length
292 to application as well in the channel_message and private_message
293 client operations. Affected files are
294 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
295 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
296 and lib/silcclient/client_ops_example.c.
298 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
299 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
300 the channel. Updated protocol specs and impelemented this
301 to client and server. Protocol TODO #6. Affected files are
302 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
303 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
305 Added new options m and M to CMODE command in Irssi SILC
306 client to set these modes.
308 * Deprecated all administrative commands from SILC protocol
309 since they are highly implementation specific commands.
310 Updated protocol specs. Moved the old commands in
311 implementations to private range of command types. Affected
312 files are silcd/command.c, lib/silcclient/command.c and
313 lib/silcclient/command_reply.c. Protocol TODO #8.
315 * Fixed a bug in server where sending unknown command crashes
316 the server. Affected file silcd/command.c.
318 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
320 * Added SILC_PROTOCOLVERSION macro to check protocol version
321 of a socket connection. The affected file is
322 lib/silcutil/silcsockconn.h.
324 * Added better error logging in rekey protocol. Affected file
327 * Do not check public key types in SKE during rekey. Affected
328 file lib/silcske/payload.c.
330 * Fixed the rekey protocol with PFS, which was totally broken.
331 Affected file silcd/protocol.c.
333 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Some client implementations quit network by doing first LEAVE
336 and then immediately SIGNOFF (like Bombyx). We now do check
337 after a short time after LEAVE notify and check whether the
338 client is still valid after LEAVE, and if not we remove it from
339 cache. Affected file is lib/silcclient/client_notify.c.
341 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
343 * Merged version 1.1.4 of zlib. Even if it not currently in use,
344 it's good not to have security holes here.
346 * Fixed a negative refcount situtuation for the config context.
347 Affected file is silcd/serverconfig.c.
349 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
351 * ROBOdoc documented lib/silcutil/silcutil.h.
353 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
355 * Optimized even more the SilcPacketContext structure. Now
356 totally saved 16 bytes of memory per context after optimization.
357 Affected files are lib/silccore/silcpacket.[ch].
359 * Made strict checks for valid SILC IDs. Affected file is
360 lib/silccore/silcid.c.
362 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
364 * Changed the object argument for silc_cipher_register,
365 silc_hash_register, silc_hmac_register and silc_pkcs_register
366 to const. Affected files are lib/silccrypt/silccipher.[ch],
367 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
369 * Changed the silc_get_username and silc_get_real_name to
370 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
372 * Fixed the Irssi SILC Client to use the silc_get_username and
373 silc_get_real_name insted of glib routines since the glib
374 routines only corrupt stack. Fixes the Irssi SILC to work in
375 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
377 * Fixed the Irssi to not use g_get_home_dir since it crashes
378 or returns garbage on cygwin and corrupts stack. Added function
379 get_home_dir to Irssi routines. Affected files are
380 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
382 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Made some structure optimizations. SFTP memory FS MemFSEntry
385 entry structure. Optimized SilcTask structure. Optimized
386 SilcPacketContext structure.
388 Affected files lib/silcsftp/sftp_fs_memory.c,
389 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
391 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
393 * And yet again reverted back the config thing since Johnny
394 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
397 * Fixed memory leaks from config object. Affected files are
398 silcd/serverconfig.[ch].
400 * Added support for adding new connections to the server in rehash.
401 After rehash they take effect.
403 Added support for changing the maximum allowed connections in
404 rehash. The number can grow but going smaller is not supported.
406 Added function silc_server_num_sockets_by_remote to the
407 silcd/server_util.[ch].
409 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
411 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
413 * Added preliminary checking during config parsing for a valid
414 public/private key and removed further checks in the code.
415 Affected files are silcd/serverconfig.[ch], server.c.
417 * Moved functions silc_server_drop() and silc_server_daemonise()
418 from server.c to silcd.c since they are stricly related to
419 the application activity.
421 * Reverted a small part of the automatic ref/unref since
422 it caused a double unref in some situations. Affected
423 files are silcd/silcd.[ch], server.c, serverconfig.c.
425 * Added some .cvsignore files in the lib directory.
427 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
429 * Fixed silc_net_gethostbyaddr to correctly resolve by
430 address. Affected file lib/silcutil/silcnet.c.
432 * Fixed the notify relaying to client. The HMAC to be used
433 with relayed packets ws wrong and caused decryption failure
434 at the client end. Affected file is silcd/packet_receive.c.
436 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
438 * Created new branch silc_protocol_1_0_branch.
440 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
442 * Changed the silc_server_config_* routines to be SilcServer
443 independent. They are now officially application specific code
444 and not part of generic server implementation. Affected files
445 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
447 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Added automatic referencing of config context in the
450 silc_server_config_alloc, and automatic unreferencing in the
451 silc_server_config_destroy. Affected files are
452 silcd/serverconfig.[ch], silcd/silcd.c.
454 * Fixed the silc_log_quick handling in the logging routines.
455 It didn't log quickly when it was TRUE. Affected file is
456 lib/silcutil/silclog.c. Also the flush delay was set even
457 if it was 0 in config file. Affected file is
458 silcd/serverconfig.c.
460 * Added support for changing key pair of the server in rehash.
461 Affected file silcd/server.c.
463 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
465 * Fixed the TOPIC_SET notify to not cras. It changed the topic
466 too early, before getting the channel entry. Affected file
467 is silcd/packet_receive.c.
469 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
471 * Added functions silc_server_config_[ref/unref], these are used
472 to prevent that the config object is destroyed.
474 No longer directly affect global variables silc_log_quick and
475 silc_log_delay, they are first cached inside the config object
476 and then applied with silc_server_config_setlogfiles().
478 silc_server_config_set_defaults() is now internal to
479 serverconfig.c, there are no reasons to show this internal stuff
482 Affected files are silcd/serverconfig.[ch].
484 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
485 fprintf's to stderr, since some code may be executed again after
486 the server went into the background. Affected files are
489 * Added rehash support. Added function silc_server_rehash() that
490 will perform all the basic tasks of the rehashing procedure.
492 * Added command line option `-x, --hexdump'. This will enable the
493 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
494 The option `--hexdump' implies `--debug'.
496 * Fixed a bad bug in the logging APIs (silcutil library) where
497 the application would crash after calling silc_log_reset_all().
499 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
501 * Fixed the KICKED notify handling in client library to
502 correctly remove the channel and all entries from the
503 channel when I was kicked. This bug crashed the client.
505 Fixed yet another but in KICKED notify handling to remove
506 the kicked client correctly from the channel.
508 Affected file is lib/silcclient/client_notify.c.
510 * Fixed a minor bug in looking up correct client entry
511 in KICKED notify in server. Affected file is
512 silcd/packet_receive.c.
514 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
515 sources correctly to distribution. Fixes --with-gmp option.
517 * Removed the manual rehashing from ID Cache, and changed it
518 to use the SILC Hash Table's auto rehash feature. Affected
519 file is lib/silccore/silcidcache.c.
521 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
523 * Fixed a bug in the silc_client_nickname_format function that
524 handles the multiple same nickname formatting. Two clients
525 with same nickname caused problems after the first one left
526 and rejoined. It didn't format the nickname correctly.
527 Affected file is lib/silcclient/idlist.c.
529 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
531 * Don't change the topic if olod topic is same as new one.
532 Affected file is silcd/packet_receive.c.
534 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
536 * Added cross-reference support to the SILC Documentation
537 generator. All types across all HTML files are now cross-
538 referenced. Affected files util/robodoc/generator.c and
539 scripts/silcdoc/silcdoc.
541 * Added file lib/silcutil/silctypes.h to include all the
542 arithmetic type definitions and some macros. Removed
543 includes/bitmove.h and moved macros to silctypes.h.
545 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
547 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
549 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Added `type' argument to silc_id_payload_parse_id function which
552 now returns the type of the ID to the sent pointer. Affected
553 file is lib/silccore/silcid.[ch].
555 * Added check for CMODE_CHANGE notify type that mode change is
556 allowed by the sender. Affected file silcd/packet_receive.c.
558 * Added check for CUMODE_CHANGE notify type that mode change is
559 allowed by the sender. Affected file silcd/packet_receive.c.
560 Added the ID type as CUMODE_CHANGE notify type as argument
561 to the `notify' client operation. Affected files are
562 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
564 * Added function silc_client_add_server to the client library.
565 Added support for resolving also channel and server info when
566 received unknown entity in notify packet. Affected files are
567 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
569 * Added function silc_command_get_status to return the command
570 status from the command reply's argument payload. Affected files
571 are lib/silccore/silccommand.[ch].
573 * Added check for KICKED notify type that the kicking is
574 allowed by the client. Affected file silcd/packet_receive.c.
576 * Created function silc_get_input which can be used to get input
577 (echo on or off) from user on command line. Affected files are
578 lib/silcutil/silcutil.[ch].
580 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
582 * Optimized silc_server_packet_relay_to_channel function.
583 Added new function silc_channel_message_payload_encrypt which
584 can be called directly if channel message payload needs to
585 be encrypted and is already encoded (no need to call _encode
586 function). Packet relaying is now done by router without any
587 extra memory allocations. Affected files are
588 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
591 * Fixed the INVITE notify handling. It took wrong arguments
592 as invite list and invite delete. Affected file is
593 silcd/packet_receive.c.
595 * Added check for TOPIC_SET notify type that the topic change is
596 allowed by the client. Affected file silcd/packet_receive.c.
598 * Added check for INVITE notify type that inviting is allowed by
599 the client. Affected file silcd/packet_receive.c.
601 * Changed the silc_server_client_on_channel to return the
602 SilcChannelClientEntry as well. Moved the function
603 silc_server_check_cmode_rights to server_util.[ch].
604 Affected files are silcd/server_util.[ch], silcd/command.c.
606 * Added function silc_server_check_umode_rights to check whether
607 changing client's user mode is allowed. Added check for
608 UMODE_CHANGE notify type that the umode change is allowed
609 by the client. Affected files are silcd/server_util.[ch],
610 silcd/packet_receive.c and silcd/command.c.
612 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
615 ID length. It ignored that ID can be IPv6 based as well.
616 Affected file lib/silccore/silcpacket.h.
618 * Fixed the silc_id_id2str and silc_id_str2id to take the
619 IPv6 address offset's into consideration. Affecte file is
620 lib/silccore/silcid.c.
622 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
624 * Fixed the internal Unix scheduler functions to check for
625 NULL context they may receive. The affected file is
626 lib/silcutil/unix/silcunixschedule.c.
628 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
630 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
631 can specify different directory with --home command line
632 parameter. Affected files irssi/src/silc/core/client_ops.c,
635 * SILC-specific commands aren't now executed if the active server
636 isn't of SILC-type, so there won't be problems with having
637 IRC and SILC protocol support in same client. Affected files
638 irssi/src/silc/core/silc-channels.c, silc-servers.c,
641 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Improved the signal support in SILC Schedule. Added new
644 function silc_schedule_signal_call which is used by application
645 to mark a signal to be called. It is now safe to perform
646 any kind of tasks in signal callbacks since it is guaranteed
647 that the application specified signal callback is called
648 after the signal is over. Affected files are
649 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
651 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
653 * Added `name' field to SilcChannelPrivateKey to represent
654 application given name for the key. Moved also the context from
655 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
656 Added the `name' argument also to the function
657 silc_client_add_channel_private_key.
659 Added function silc_client_current_channel_private_key to set the
660 current channel private key in use.
662 Added "change" command to KEY command which can be used to change
663 the current channel private key. Bound the command also to
666 Also affected files lib/silcclient/client_channel.c,
667 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
669 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
671 * Added silc_rng_get_byte_fast function in to the
672 lib/silccrypt/silcrng.[ch].
674 * Changed the interface of silc_packet_assemble and the
675 silc_packet_send_prepare. If silc_packet_assmble is now
676 called the application does not call silc_packet_send_prepare
677 because the library will call it automatically. These
678 interfaces now also return a reference to the outgoing buffer
679 which includes the assembled packet, which the application can
680 use to encrypt the packet.
682 Affected files are lib/silccore/silcpacket.[ch],
683 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
684 silcd/packet_send.c, server_backup.c and packet_receive.c.
686 * Fixed a packet sending bug on very high load, where outgoing
687 packet queue wasn't handled correctly and packets got corrupted.
688 Affected files are lib/silcutil/*/silc*sockconn.c,
689 lib/silcclient/client.c and silcd/server.c.
691 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
693 * Added macro SILC_PACKET_DATALEN which can be used during
694 packet assembling to check whether the data to be added to
695 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
696 len is truncated until it fits it.
698 Added checks for maximum length of channel message payload and
699 private message payload also.
701 Added checks for maximum packet length in server and in
704 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
705 lib/silcclient/client.c, lib/silccore/silcchannel.c and
706 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
707 lib/silcclient/client_prvmsg.c.
709 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
711 * Added silc_server_packet_queue_purge call to the
712 silc_server_disconnect_remote to assure that all data in the
713 queue before disconnecting is sent to the network. Affected
716 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Added the deleting of server's own ID cache entry to the
719 silc_server_free function. Free also everything else that
720 has been allocated in silc_server_init. The affected file
723 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Added functions silc_parse_version_string, silc_version_to_num,
726 and silc_ske_parse_version to parse SILC protocol style version
727 strings. Affected files lib/silcutil/silcutil.[ch] and
728 lib/silcske/silcske.[ch].
730 * Added new configuration params: version_protocol, version_software
731 and version_software_vendor to specify what version the remote
732 host must at least be to be able to connect to server. The vendor
733 string can be regex matched too. Added new function
734 silc_server_connection_allowed to check maximum number of allowed
735 connections, and allowed versions for incoming connections.
736 Affected files are silcd/server.c, server_util.[ch] and
739 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Added preliminary support for signals in scheduler. The
742 signals we care about are now blocked always when the scheduler
743 is locked. This way we can synchronise the use of signal with
744 scheduler. It is guaranteed that when signal occurs the scheduler
745 is not locked, and thus new tasks can be safely added to the
748 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
749 to silc_schedule_internal_init and silc_schedule_internal_uninit.
750 Added new platform specific routines
751 silc_schedule_internal_signals_[un]block and
752 silc_schedule_internal_signal_[un]register.
754 Added new functions to SILC Schedule API:
755 silc_schedule_signal_[un]register. Each signal that application
756 is going to use should be registered to the scheduler.
758 Affected files are lib/silcutil/silcschedule.[ch],
759 lib/silcutil/*/silc*schedule.c.
761 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Check for unauthenticated client and server in the
764 silc_server_new_client and silc_server_new_server functions.
765 Affected file silcd/packet_receive.c.
767 * Added function silc_string_is_ascii to check whether given
768 string is 7-bit ASCII string. Affected files are
769 lib/silcutil/silcutil.[ch].
771 * Added function silc_id_is_valid_server_id into the
772 silcd/serverid.c and added checking for valid Server ID's in
773 silc_server_new_server. The Server ID must always be based
774 on the server's public IP address.
776 * Added logging of DISCONNECT packet message in the server.
777 Affected file silcd/server.c.
779 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
781 * Changed all library interfaces that use Global RNG to also
782 accept SilcRng as argument. Affected files are
783 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
784 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
785 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
786 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
789 * Added function silc_pkcs_generate_key to the
790 lib/silccrypt/silcpkcs.[ch] for applications so that they
791 don't need to do pkcs->pkcs->init calls anymore.
793 * Remove SilcSocketConnection from the SFTP API since it really
794 wasn't needed there. The application has the information
795 saved in its contexts anyway and the SFTP layer doesn't need
796 know about it. Affected files lib/silcsft/silcsftp.h and
797 lib/silcsftp/sftp_[server/client].c.
799 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
800 The SilcSimContext is not SilcSim.
802 * Fixed possible buffer overflows in silc_id_render in the
803 lib/silcutil/silcutil.c.
805 * On EPOC the global crypto module lists are not used at all
806 in the crypto library. Added support for using the constant
807 algorithm list on EPOC. Affected files are
808 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
811 * Fixed the handling of third parameter of KICKED notify, since
812 it was mistakenly updated to SILC Protocol 1.0 even though it
813 is to be included in 1.1. Since it is not in 1.0 it is not
814 mandatory, and this fix now handles it only if it is provided,
815 and it is not error if it is not provided. Affected file
816 lib/silcclient/client_notify.c.
818 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
820 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
821 client. Affected file irssi/src/silc/core/client_ops.c.
823 * Merged with Irssi 0.8.4 from irssi.org CVS.
825 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
827 * Check for valid socket connection in client entries before
828 sending any messages. Fixes a crash, but doesn't fix some
829 other underlaying bug that is lurking there. Affected
830 file silcd/packet_send.c.
832 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
834 * $usermode, $cumode and $cumode_space expandos shouldn't do
835 anything with non-SILC server records. Affected file
836 irssi/src/silc/core/silc-expandos.c
838 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
840 * Fixed the silc_net_check_[host/local]_by_sock to support
841 IPv6 bound sockets as well. Now they can return IPv6 addresses
842 as well. Affected file lib/silcutil/silcnet.c.
844 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
845 Affected lib/silcutil/unix/silcunixnet.c.
847 * Fixed ID rendering (at least on some platforms, not NetBSD)
848 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
850 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
852 * Added silc_hash_public_key and silc_hash_public_key_compare
853 functions to be used with SilcHashTable. They can be used to
854 hash public keys and compare public keys in hash table. Affected
855 file lib/silcutil/silcutil.[ch].
857 * Added support for specifying multiple public keys for Client
858 connection section in server configuration file. This makes it
859 possible to accept multiple public keys from same host, or to
860 make a section that accepts any incoming host, and have the
861 accepted public keys listed in the section.
863 Added functions silc_sever_[find/get]_public_key, added the
864 support for this actually to all connection sections but only
865 the Client section is currently allowed to specify multiple
868 Affected files are silcd/server.c, server_internal.h,
869 command.c, protocol.c, server_util.[ch], packet_receive.c.
871 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Merged Irssi 0.8.2 from irssi.org CVS.
875 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
877 * If silc_debug is TRUE, also output standard logging messages
878 to stderr with the debug output.
880 Made silc_log_reset_all() flushing all channels before returning.
881 Also fixed some documentation typos.
883 Affected files are lib/silcutil/silclog.[ch].
885 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
887 * Fixed the server to check correctly the amount of connections
888 from single host, by checking also the type of the connection.
889 Fixed also the comparison of number of connections and number
890 of allowed connections. Affected files are silcd/server.c,
893 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Fixed the USERS command reply to save the user's mode on the
896 channel as well. Fixed JOIN command reply to check whether a
897 client is on channel already and not join it twice. Affected
898 file lib/silcclient/command_reply.c.
900 * Added new file silc-expandos.c into irssi/silc/core/ to return
901 various stuff for various signal for the statusbar etc. updating.
902 Now Irssi SILC client prints channel user modes etc. on the
905 * The user mode (like server/router operator changes) is now shown
906 on the Irssi SILC client's statusbar. The affected files are
907 irssi/src/silc/core/client_ops.c, silc-expandos.c.
909 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
911 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
912 to SILC_SCHEDULE_[UN]LOCK macros.
914 * Added more error printing to logs in server code. Affected
915 files silcd/server.c and silcd/protocol.c.
917 * Fixed -S option parsing in Irssi SILC Client. Affected file
918 irssi/src/silc/core/silc-core.c.
920 * Added silc_buffer_alloc_size function. Affected file is
921 lib/silcutil/silcbuffer.h.
923 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
925 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
926 constants. Affected files in
927 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
930 * Changed the internal SFTP Memory FS table to const. Affected
931 file lib/silcsftp/sftp_fs_memory.c.
933 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
935 * Fixed the buffer formatting and unformatting routines to
936 check the size of 64 bits types with sizeof(). Affected
937 file is lib/silcutil/silcbuffmt.c.
939 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * Removed 0.6.x backwards support.
943 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
945 * Changed all integer type names:
946 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
947 to avoid collisions with other libraries using same type names
950 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Added `prefer_ipv6' argument to the functions
953 silc_net_gethostbyname[_async]. If it is TRUE it will return
954 IPv6 address over IPv4. If FALSE IPv4 address is returned
955 even if IPv6 address was found. Affected files
956 lib/silcutil/silcnet.[ch].
958 * Added support silc_net_create_connection[_async] to fallback
959 to IPv4 address if IPv6 address could not be used (like if
960 it doesn't work on a specific system). Affected file in
961 lib/silcutil/unix/silcunixnet.c.
963 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
965 * Added silc_schedule_reinit function to do the enlarging
966 of the max tasks handling capabilities of the scheduler.
967 Affected files lib/silcutil/silcschedule.[ch].
969 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Added automatic extern "C" { ... } for C++ compilers so the
972 application does not need to define them. Affected file
973 includes/silcincludes.h.
975 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
976 old name went against naming convention. Applications now
977 include "silcclient.h" instead of "clientlibincludes.h".
978 Removed includes/clientlibincludes.h, it is redundant now.
980 * Renamed includes/version.h to silcversion.h.
982 * Added really preliminary support for OS/2 into the util
983 library. Only thread & mutex API is implemented, others
984 are still to be implemented. Created the lib/silcutil/os2/
985 directory. Created also file includes/silcos2.h.
987 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
989 * Added preliminary BeOS support into the util library.
990 Created lib/silcutil/beos/, and implemented all the needed
991 functions to support SILC on BeOS. Created also file
994 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
996 * Added proper initializations to silc's irssi code, so it's
997 now possible to load it as module. Affected files
998 irssi/src/silc/core/silc-core.c,
999 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1001 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1003 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1006 * Fixed the silcdoc document generator to correct generate
1007 docs from all kinds of filenames. Affected files are
1008 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1010 * ROBOdoc documented lib/silcutil/silcmemory.h.
1011 Added also new function silc_memdup.
1013 * Removed lib/silcutil/silcbufutil.h and moved those routines
1014 to the lib/silcutil/silcbuffer.h.
1016 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1018 * Added `user_count' to the SilcChannelEntry which now tells the
1019 number of users on the channel. The user count is now saved
1020 in normal server of global channels as well. Affected files
1021 silcd/server.c, idlist.h, packet_receive.c and command.c.
1023 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1024 include file utility functions.
1026 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1027 instead of calling directly OS routines.
1029 * Fixed NICK change printing in Irssi SILC Client. Fixed
1030 KICKED notify printing in Irssi SILC Client. Affected file
1031 irssi/src/silc/core/client_ops.c.
1033 * Fixed a NICK change bug in client library, to not recreate the
1034 client_entry->channels hash table everytime nick is changed.

1039 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1040 the SKE interface a bit.
1042 * Fixed padding problem in PKCS#1. The padding was not actually
1043 random since the random number generator was used incorrectly.
1044 This security bug affects only when encrypting with PKCS#1, and
1045 it is not currently used at all in SILC. SILC only use signing
1046 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1048 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1058 * Added following new config file settings:
1059 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1060 key_exchange_timeout, conn_auth_timeout, connections_max,
1063 Implemented all the new config settings handling in the server.
1065 Optimized the use of SKE Mutual flag usage. Use it only
1066 if connection authentication protocol is not based in public
1069 Renamed all SilcServerConfigSection* to SilcServerConfig*
1070 to have a bit shorter names.
1072 Affected files silcd/serverconfig.[ch], server.[ch], and
1075 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1101 Affected files are silcd/serverconfig.[ch].
1103 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1105 * Fixed command line parameter handling. All SILC initialization
1106 is now done in silc_core_init() which also fixes autoconnecting
1109 Affected files irssi/src/silc/core/silc-core.c,
1110 irssi/src/fe-text/silc.c.
1112 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1114 * Added new configuration options and blocks:
1115 keepalive_secs, reconnect_count, reconnect_interval,
1116 reconnect_interval_max, reconnect_keep_trying and
1117 require_reverser_lookup. Added ConnectionParam block, and
1118 implemented the connection parameters when connecting as
1119 initiator and when accepting connections as responder.

1122 whether given configuration value has been given already.
1124 Affected files silcd/serverconfig.[c], server.[c].
1126 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1127 algorithm parts and created new file silcalgs.conf, that
1128 is now included from the example_silcd.conf.in.
1130 * Optimized the silc_server_connect_to_router_second to take
1131 the connection configuration object from the SilcServerConnection
1132 object instead of finding it during the connecting phase.
1133 Added the configuration object to SilcServerConnection struct.
1134 Affected files silcd/server_internal.h, server.c.
1136 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Add the client on channel after it was resolved at the
1139 channel message receiving, and it was not already on the
1140 channel. Affected file lib/silcclient/client_channel.c.
1142 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed the public key authentication to allocate always the

1156 * Added new Passphrase and Publickey authentication methods to
1157 config file, allowing both public key and passphrase based
1158 authentication to be set at the same time.
1160 Added `prefer_passphrase_auth' setting in config file which
1161 can be used to set to prefer passwd auth if both passwd and
1162 public key is set. If not set, public key is preferred.
1163 This has effect only when being initiator (responder will try
1166 Added support for authentication with passphrase and public key
1167 at the same time. The passphrase is tried first always since
1168 it is faster to check.
1170 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1172 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1174 * Merged the new SILC Config library, with the server parsing
1175 support. Read the header file silcconfig.h or the toolkit
1176 documentation for the news. Affected files are

1199 Payload. Affected file lib/silccore/silcchannel.c.
1201 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1202 as header filenames.
1204 * Removed lib/silcclient/README and created HTML file
1205 lib/silcclient/silcclient_using.html, which is now included
1206 as part of Toolkit documentation.
1208 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1210 * Fixed CUMODE_CHANGE notify handling to change the mode of
1211 correct client. Affected file lib/silcclient/client_notify.c.
1213 * Make silc_rng_alloc fail if it cannot allocate the sha1
1214 hash algorithm. Affected file lib/silccrypt/silcrng.c.

1218 * Fixed the file transfer's key agreement payload to include
1219 zero port also if the hostname is NULL because it could not
1222 Call file transfer monitor callback now also if error occurs
1223 during key agreement protocol.
1225 Changed the silc_client_file_send interface to return the
1226 SilcClientFileError instead of session id. The session ID
1227 is returned into pointer provided as argument.
1229 Check that the file exists locally before sending the
1230 file transfer request at all.
1232 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1234 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1235 error than can occur while key agreement protocol. Affected
1236 file lib/silcclient/silcapi.h.
1238 * Fixed the event_mode CMODE handler to not crash when mode
1239 is changed and +k mode is set in the channel. Affected file
1240 irssi/src/silc/core/silc-channels.c.
1242 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1243 SILC_LOG_WARNING to give out Warning and not Error. Affected
1244 file lib/silcutil/silclog.c.
1246 * Fixed the channel message payload decryption in the function
1247 silc_channel_message_payload_decrypt to not modify the original
1248 buffer before it is verified that the message decrypted
1249 correctly. Otherwise, next time it is called with correct
1250 channel key it won't encrypt since the payload is corrupted.
1251 Affected file lib/silccore/silcchannel.c.
1253 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1263 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1265 * Fixed a bug in hash table internal routine for traversing
1266 the table with foreach callback. The current entry may
1267 become invalid in the callback but it was referenced after
1268 the callback returned.
1270 Do not allow auto rehashing of hash table during the
1271 silc_hash_table_foreach operation, for same reasons as it is
1272 not allowed for SilcHashTableList. Affected files are
1273 lib/silcutil/silchashtable.[ch].
1275 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1277 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1278 Win32 DLL. extern's in header files are now declared with
1281 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1283 * Fixed private message handling. It used some old code that
1284 caused the client to crash. Affecte file is
1285 lib/silcclient/client_prvmsg.c.
1287 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1289 * Added function silc_client_add_channel,
1290 silc_client_replace_channel_id, and removed functions
1291 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1292 from client library.
1294 * Added cross reference of the joined channels to the
1295 SilcClientEntry, and changed the SilcChannelEntry's
1296 users list to SilcHashTable. The affected files are
1297 lib/silcclient/idlist.[ch].
1299 * Fixed a bug in hash table tarversing. While the hash table
1300 is traversed with SilcHashTableList the table must not be
1301 rehashed. It is now guaranteed that auto rehashable tables
1302 are not rehashed while tarversing the list. Also defined that
1303 silc_hash_table_rehash must not be called while tarversing
1304 the table. Added function silc_hash_table_list_reset that must
1305 be called after the tarversing is over. The affected files are
1306 lib/silcutil/silchashtable.[ch].
1308 * Changed all hash table traversing to call the new
1309 silc_hash_table_list_reset in server and in client library.
1311 * Added function silc_client_on_channel to return the
1312 SilcChannelUser entry if the specified client entry is joined
1313 on the specified channel. This is exported to application as
1314 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1316 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1318 * Fixed founder regaining problem with JOIN command on normal
1319 server. The notify for mode change must be sent always and
1320 not only if !cmd->pending. Affected file silcd/command.c.
1322 * Fixed the WHOWAS command's reply sending to support the
1323 lists correctly. Affected file silcd/command.c.
1325 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1327 * When sending JOIN command to router for processing the
1328 sender's old command identifier was not saved back to the
1329 sender's command context, fixed now. The affected file is
1332 * Create the key in JOIN command of the router did not return
1333 the channel key, added check for this. Affected file is
1336 * Fixed a channel ID update bug in JOIN command reply. Do
1337 not directly upgrade the ID but call the function
1338 silc_idlist_replace_channel_id if the ID was changed.
1339 Affected file silcd/command_reply.c.
1341 * Fixed memory leaks from command calling if it would fail.
1342 Affected file silcd/command.c.
1344 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * Applied patches from cras:
1348 Memory leak fixes around libaries, irssi window resize fix,
1349 new silclist.h and silcdlist.h, all extern inline changed to
1352 * Removed dotconf from lib/dotconf, not needed anymore.
1354 * Removed TRQ from lib/trq, not needed anymore.
1356 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1357 with server connections. Later this will be configurable
1358 in config file after new config file is done. Affected file
1361 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1363 * Fixed a crash in server related to channel announcements.
1364 Affected file silcd/server.c.
1366 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1368 * Fixed memory leaks in silc_server_create_new_channel*
1369 functions. Affected file silcd/server.c.
1371 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1372 which ID was changed. This way the router will send the
1373 user list for the channel again, and server won't be in
1374 desync in some rare circumstances. Affected file is
1375 silcd/packet_receive.c.
1377 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * Check for NULL socket pointer in the function

1388 * Fixed some header addition to Toolkit distribution in
1389 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1391 * Added lib/silcclient/client_ops_example.h as an template
1392 file for application programmers to quickly start using
1393 the SilcClientOperation functions in their application.
1394 Updated the lib/silcclient/README as well to tell about this
1395 nice file made available.
1397 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1399 * Call silc_server_remove_from_channels when removing client
1400 entry when NO_SUCH_CLIENT_ID was received. Affected file
1401 is silcd/command_reply.c.
1403 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1405 * Added server & router operator statistics updating. Affected
1406 file silcd/packet_receive.c and silcd/command.c.
1408 * Fixed the SERVER_SIGNOFF notify handling on normal server
1409 not to save the history information for clients. Same was
1410 fixed earlier in remove_clients_by_server function, but not
1411 here. Affected file silcd/packet_receive.c.
1413 * Raised the default connection-retry count from 4 to 7 in
1414 server. Affected file silcd/server.h.
1416 * Cancel any possible reconnect timeouts when we start the
1417 key exchange. Affected file silcd/server.c.
1419 * Do not reconnect on connection failure when SCONNECT was
1420 given. Affected files silcd/server.[ch].
1422 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1424 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1426 * Fixed the NICK command to always give the unformatted
1427 nickname to the one giving the NICK command. If unformatted
1428 nickname is cached already it will be formatted and the
1429 local entry will always get the unformatted nickname.
1430 Affected file lib/silcclient/idlist.c.
1432 * Fixed some double frees from client library commands.
1433 Affected file is lib/silcclient/command.c.
1435 * Fixed CUMODE command in server to assure that no one can
1436 change founder's mode than the founder itself, there was a
1437 little bug. Affected file silcd/command.c.
1439 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1441 * Removed the SilcClientCommandDestructor from the client
1442 libary, it is not needed anymore. Affected files are
1443 lib/silcclient/silcapi.h, command[_reply].[ch],
1444 client_notify, idlist.c.
1446 * Fixed GETKEY command to first resolve client, and then
1447 resolve the server only if the client was not found, instead
1448 of resolving both at the same time. Affected file is
1449 lib/silcclient/command.c.
1451 * Added silc_client_start_key_exchange_cb and lookup the
1452 remote hostname and IP address before starting the key
1453 exchange with server. The affected file is
1454 lib/silcclient/client.c.
1456 * The server's public key is now saved using the IP address
1457 of the server and not the servername for the filename.
1458 The hostname public key filename is checked as an fall back
1459 method if the IP address based filename is not found.
1461 Fixed the GETKEY command to save the fetched server key
1462 in correct filename.
1464 Print the remote server's hostname now when new key is
1465 received during connection process. Affected file is
1466 irssi/src/silc/core/client_ops.c.
1468 * Return always our own public key to the client if it asks
1469 for it with GETKEY command. Affected file silcd/command.c.
1471 * Removed the use_auto_addr variable from default config
1472 file since it was in wrong section. Affected file is
1475 * Fixed TOPIC_CHANGE notification to not route it when it
1476 was sent using silc_server_send_notify_to_channel function.
1477 Affected file silcd/command.c.
1479 * Fixed silc_server_send_notify_kicked to send the kicker's
1480 Client ID also, it was missing. Affected files are
1481 silcd/command.c, silcd/packet_send.[ch].
1483 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1485 * Do not save client history information in SERVER_SIGNOFF.
1486 Fixes the bug in normal server that it does not detect
1487 the client becoming valid after the server becomes back
1488 online. Affected file silcd/server_util.c.
1490 * Added `sock_error' field into the SilcSocketConnection
1491 context. When error occurs during socket operation (read
1492 or write) the error is saved. Added also new function
1493 silc_socket_get_error to return human readable socket error
1494 message. Affected files are lib/silcutil/silcsockconn.[ch],
1495 lib/silcutil/unix/silcunixsockconn.c, and
1496 lib/silcutil/win32/silcwin32sockconn.c.
1498 * The server now prints the socket error message in the
1499 signoff for client. Affected file silcd/server.c.
1501 * Fixed the `created' channel information sending from router
1502 to server in JOIN command. Checks now whether the channel
1503 really was created or not and set it according that.
1505 Fixed the JOIN command to use the client entry's current
1506 ID during the joining procedure instead of the one it sent
1507 in the command (it is checked though), since it can change
1508 between the packet processing and command processing, and
1509 would just case unnecessary pain in the client end. Affected
1510 file silcd/command.c.
1512 * Fixed a channel key payload sending to use correct channel
1513 ID when the server was forced to change the channel's ID by
1514 router. Router sent the key payload with the old Channel ID.
1515 Affected file silcd/packet_receive.c.
1517 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1519 * Call silc_server_save_channel_key only if the key payload
1520 was provided in the JOIN command's command reply. Affected
1521 file silcd/command_reply.c.
1523 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Fixed silc_mp_sizeinbase to return the value correctly with
1526 MPI. Affected file lib/silcmath/mp_mpi.c.
1528 * Fixed the stop_server signal to correctly stop the scheduler
1529 and gracefully stop the server when SIGTERM or SIGINT signals
1530 are received. Affected file silcd/silcd.c.
1532 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1534 * Simple handling of TERM and HUP signals. Also added some log
1535 flushing call around. Affected file is
1538 * Fixed small bugs in silclog.c. Now buffering output will take
1539 effect after 10 seconds since startup: This will ensure that
1540 no important startup messages are lost. Also output redirection
1541 will preserve original format ([Date] [Type] message).
1542 Affected file is lib/silcutil/silclog.c.
1544 * Added two options to the config file, in the logging section:
1545 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1546 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1548 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1550 * Do not print the warning about log files not being initialized
1551 more than once to avoid excess logging. Affected file is
1552 lib/silcutil/silclog.c.
1554 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1555 the SIM copying in make install in Makefile.am.pre.
1557 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1559 * Rewritten silclog APIs. Globally interesting changes follows:
1560 silc_log_set_files() changed to silc_log_set_file().
1561 silc_log_set_callbacks() changed to silc_log_set_callback().
1562 ROBOdoc documented silclog header file.
1563 SilcLogCb now returns bool to wether inihibit the default
1564 handler or not (to keep the old behaviour return always TRUE).
1565 The new APIs should also fix the problem of the
1566 silcd_error.log file that was written in the current directory.
1569 Log files streams will remain opened after silc_log_set_file()
1570 call, means less CPU usage notably on high traffic servers.
1571 File streams are now full buffered, and flushed to the disk
1572 every 5 minutes, lesses HD activity and CPU usage.
1573 Messages can be redirected, allowing admins to configure
1574 one single logfile for all server messages.
1575 the silc_log_quick global variable to activate fast-logging.
1576 Affected files lib/silcutil/silclog.[ch]
1578 * Changed some code to conform new silclog APIs. Affected
1579 files are doc/example_silcd.conf.in, silcd/server.c
1580 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1583 * Fixed a memory leak that could occur in some situations.
1584 Affected file silcd/serverconfig.c.
1586 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1588 * Added the silc_client_del_client to remove the client from
1589 all channels as well. Affected file lib/silcclient/idlist.c.
1591 * Fixed the client library to correctly remove the client
1592 from all channels when the client entry is being destroyed.
1593 Affected file lib/silcclient/client_notify.c, command.c.
1595 * Added auto-nicking support to the client library. If the
1596 applicatio now sets client->nickname it will be sent to the
1597 server after connecting by the library. This way for example
1598 SILCNICK (or IRCNICK) environment variables will have effect
1599 and always change the nickname automatically to whatever
1600 it is wanted. Affected file lib/silcclient/client.[ch].
1602 * Renamed silc_server_command_bad_chars to the
1603 silc_server_name_bad_chars and moved it to the
1604 silcd/server_util.[ch]. Added also new function
1605 silc_server_name_modify_bad to return nickname that
1606 includes bad characters as new nickname without those
1607 bad characters. This check and modify is now used in
1608 silc_server_new_client when the username is initially set
1609 as nickname, so it must be checked to be valid nickname.
1610 Affected file silcd/packet_receive.c.
1612 * The nickname length is now taken from the packet for real
1613 and not trusted to strlen() since it clearly can return
1614 wrong length for nickname including bad characters. This
1615 also applies to channel names. Affected file silcd/command.c.
1617 * Removed the lib/silcsilm/modules directory. Modules are now
1618 compiled into the lib/silcsim. Fixed the copying of the
1619 modules to follow symbolic links in Makefile.am.pre.
1621 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1623 * Fixed silc_string_regexify list creation. Fixes bugs with
1624 BAN and INVITE commands in server. The affected file is
1625 lib/silcutil/unix/silcunixutil.c.
1627 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Removed the command destructor entirely from the server's
1630 command and command reply routines. It is not needed, and
1631 its usage was buggy and caused crashes. Affected files are
1632 silcd/command[_reply].[ch].
1634 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Cancel protocol and NULL sock->protocol if timeout
1637 occurred during protocol. Affected file silcd/server.c.
1639 * Cancel protocol timeouts always before calling the final
1640 callback, to assure that after final callback is called
1641 no other state will be called for the protocol anymore.
1642 Affected file silcd/protocol.c.
1644 * Print error log if incoming connection configuration could
1645 not be found. Affected file silcd/server.c.
1647 * Fixed JOIN command to correctly save the founder mode
1648 to the client on normal SILC server, when the channel
1649 was created by the router. Affected file silcd/command.c.
1651 * Fixed LIST command (hopefully) to send correct reply
1652 packets. Affected file silcd/command.c.
1654 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * The silc_packet_receive_process now returns FALSE if the
1657 read data was invalid packet, and TRUE if it was ok.
1659 The server now checks that if unauthenticated connection
1660 sends data and its processing fails the server will close
1661 the connection since it could be a malicious flooder.
1663 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1665 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Make sure the warning about error opening a log file is
1668 printed only once and not everytime it fails (produces
1669 too much useless log). Affected file lib/silcutil/silclog.c.
1671 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1673 * Made the silc_server_daemonise() function more readable.
1674 Affected file silcd/server.c.
1676 * Pid file is now optional, the user may comment it out from
1677 the config file. Removed define SILC_SERVER_PID_FILE, we
1678 don't need a default any longer. Affected file
1679 configure.in.pre, lib/Makefile.am.pre.
1681 * Make some use of the pid file. The server now dies at startup
1682 if it detects a valid pid file on his path. The server would
1683 die anyway in this circumstance, because of the bind() failure.
1684 Affected file silcd/silcd.c.
1686 * No longer compiling lib/dotconf.
1688 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Fixed JOIN command parsing not to crash. Affected file
1691 lib/silcclient/command.c.
1693 * Fied the NICK_CHANGE notify to add the new client entry
1694 even it is resolved. This removes an <[unknown]> nick
1695 thingy bug in the client. Affected file is
1696 lib/silcclient/client_notify.c.
1698 * Do not try to allocate 0 bytes (efence does not like it)
1699 in lib/silccore/silccomand.c when encoding payload.
1701 * Do not take IRCNICK as nickname in Irssi SILC client since
1702 it is not possible to set nickname before hand connecting
1703 the server (TODO has an entry about adding auto-nicking
1706 * Changed the silc_server_command_pending to check whether
1707 there already exists an pending entry with the specified
1708 command, command identifier and pending callback. This is
1709 to fix IDENTIFY and WHOIS related crashes that may register
1710 multiple pending commands with same identifier. Affected
1711 file silcd/command.c.
1713 * Fixed the server to reconnect to the router even if it
1714 was already reconnecting and EOF was received. This to
1715 fix a possibility that the server wouldn't ever try to
1716 auto-reconnect to the router. Affected file silcd/server.c.
1718 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Fixed the server's password authentication to use the
1721 length of the locally saved password, and not the one
1722 sent in the packet. Affected file silcd/protocol.c.
1724 * Fixed same password authentication problem in the
1725 Authentication Payload handling routines in
1726 lib/silccore/silcauth.c.
1728 * Yet another password authentication problem fixed with
1729 channel password handling in silcd/command.c.
1731 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * If first character of string in silc_parse_userfqdn is '@'
1734 then do not parse it. Affected file is
1735 lib/silcutil/silcutil.c.
1737 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed minor bug in IDENTIFY command reply sending, which
1740 caused various weird problems during JOIN when it was
1741 resolving names for users. Affected file silcd/command.c.
1743 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Fixed the IDENTIFY command reply sending to chech better valid
1746 clients. It was possible to send incomplete list of replies.
1747 Affected file silcd/command.c.
1749 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Added silc_client_command[s]_[un]register functions now to
1752 dynamically register the commands in client library. Removed
1753 the static table of commands. This allows the client library
1754 to call commands without causing the application to know about
1755 what commands library has called.
1757 Removed the INFO command reply kludge to detect when the command
1758 was called by library. Now library use its own command reply
1759 function for INFO command.
1761 Added function silc_client_command_call to call a command.
1762 Application can use it to call command, not access the structure
1765 Now all commands that are sent by the client library (not
1766 explicitly sent by application) use own command reply functions.
1768 Affected files around lib/silcclient/ and in
1769 irssi/src/silc/core/.
1771 * Fixed the WHOIS command reply sending to chech better valid
1772 clients. It was possible to send incomplete list of replies.
1774 Fixed the WHOIS and IDENTIFY to send the request to router
1775 if normal server did not do it and did not find any results.
1777 Affected file silcd/command.c.
1779 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1781 * Moved the internal data from SilcClient context into its
1782 own file, not accesible to application. Affected files
1783 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1784 and other files in client library.
1786 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Added doc/examples installation target in Makefile.am.pre.
1791 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1794 commands the found client entry will be removed from the
1795 cache, after notifying application about the error. Affected
1796 file lib/silcclient/command_reply.c.
1798 * Changed the /MSG to check for exact nickname user gave, and
1799 not let `nick' match `nick@host' if it is only one found. Now,
1800 user must type the exact nickname (like nick@host2) even if
1801 there are no more than one same nicks found. This is to avoid
1802 a possibility of sending nickname to wrong nickname since
1803 `nick' could match `nick@host'. Affected file is
1804 irssi/src/core/silc-servers.c.
1806 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Do not print "you are now server operator" or similar when
1809 giving /away command. Affected files are
1810 irssi/src/silc/core/client_ops.c, silc-servers.h.
1812 * Made the silc_server_command_pending_error_check to send
1813 the same command reply payload it received back to the
1814 original sender of the command. This way all arguments
1815 that was received by the server will be received by the
1816 client too. Affected file silcd/command.c.
1818 * Added the silc_idcache_add to return the created cache entry
1819 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1821 * Add global clients to expire if they are not on any channel.
1822 This is because normal server will never know if they signoff
1823 if they are not on any channel. The cache expiry will take
1824 case of these entries. This is done by normal servers only.
1825 The affected files are silcd/command_reply.c,
1826 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1828 * If server receives invalid ID notification for WHOIS or
1829 IDENTIFY and the ID exists in the lists, it is removed.
1830 Affected file silcd/command_reply.c.
1832 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1833 in client then client entry that it matches is searched and
1834 the nickname is printed on the screen for user. Affected
1835 file irssi/src/silc/core/client_ops.c.
1837 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Use cache entry expire time in the LIST command reply to
1840 purge old entries from the cache after the LIST command
1841 reply has been received. This way we don't have non-existent
1842 entries in the cache for too long. Affected file is
1843 silcd/command_reply.c.
1845 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * If we are normal server, and we've not resolved client info
1848 in WHOIS or IDENTIFY from router, and it is global client,
1849 we'll check whether it is on some channel. If it is not
1850 then we cannot be sure about its validity and will resolve it
1851 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1852 file silcd/command.c.
1854 * Search channel by name (if possible) rather than by ID
1855 in IDENTIFY command's command reply. Affected file is
1856 silcd/command_reply.c.
1858 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1861 Updated specs and implemented it. Affected file silcd/command.c,
1862 silcd/packet_send.c and silcd/packet_receive.c.
1864 * Implemented the <founder auth> payload handling in the JOIN
1865 command. If provided all conditions for channel joining
1866 except requirement to provide correct passphrase can be
1867 overrided by the channel founder. Updated the protocol specs.
1868 Affected file silcd/command.c.
1870 Added support for founder auth in JOIN command in client
1871 library. Fixed the parsing of the JOIN command now to support
1872 all options as they should be. The affected file is
1873 lib/silcclient/command.c.
1875 * Optimized the WHOIS and IDENTIFY commands to send the request
1876 to router only if it includes nicknames or other names. If
1877 they include only IDs then check the local cache first before
1878 routing. Affected file is silcd/command.c.
1880 * Added channels topic announcements. Affected file is
1881 silcd/packet_receive.c and silcd/server.c.
1883 * Fixed the silc_server_send_notify_topic_set to really destine
1884 the packet to channel. Affected file silcd/packet_send.c.
1886 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1887 library. Affected file lib/silcclient/client_notify.c.
1889 * Added UMODE announcements. Affected file silcd/server.c.
1891 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Memory leak fixes in:
1895 lib/silcutil/silcsockconn.c
1896 lib/silcske/silcske.c
1897 lib/silcske/groups.c
1899 lib/silccrypt/silcpkcs.c
1900 lib/silccore/silccommand.c
1901 lib/silccore/silcidcache.c
1906 * ROBOdoc documented the lib/silcske/groups.h file and a
1907 bit changed the interface for better.
1909 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1911 * Update the client entry context in the ID cache after
1912 nick change. Affected file lib/silcclient/command.c.
1913 Fixes the CUMODE command when regaining founder privileges,
1914 and a little WHOIS problem.
1916 * Fixed silc_net_gethostbyname to correctly call the
1917 inet_ntop. Affected file lib/silcutil/silcnet.c.
1919 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1921 * Added IPv6 support checking to the configure.in.pre, added
1922 also --enable-ipv6 option to override the check. Affected
1923 file configure.in.pre.
1925 * The silc_thread_create now calls the start function
1926 directly if threads support is not compiled in. Removes
1927 ugly #ifdef's from generic code. Affected files are
1928 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1930 * Added silc_net_gethostby[name/addr]_async to asynchronously
1931 resolve. Affected files are lib/silcutil/silcnet.[ch].
1933 * Added support for rendering IPv6 based server, client and
1934 channel IDs. Affected file lib/silcutil/silcutil.c.
1936 * Added support for creating IPv6 based server IDs. Affected
1937 file is silcd/serverid.c.
1939 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1941 * Added silc_net_gethostby[addr/name] into the
1942 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1943 routines. Added silc_net_is_ip[4/6]. Affected file is
1944 lib/silcutil/unix/silcunixnet.c. All routines that take
1945 address as argument now supports both IPv4 and IPv6 addresses.
1947 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1949 * Fixed LIST command reply sending in server. Affected file
1952 * Server now sends the kicker's client ID in the KICK notify
1953 to the kicked client. Affected file silcd/command.c.
1955 * The client library now parses the kickers client ID and
1956 UI displays it. Affected files lib/silcclient/client_notify.c
1957 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1959 * Made all payload parsing function prototypes consistent.
1960 They all take now const unsigned char * and uint32 pair as
1961 the payload data instead of SilcBuffer. Changes all around
1962 the source tree. Other unsigned char* -> const unsigned char*
1963 changes around the tree as well.
1965 * Optimized SFTP client and server packet sending not to
1966 allocate new buffer for each packet but to recycle the
1967 first allocated buffer. Affected files are
1968 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1970 * Optimized the SFTP client to use SilcList instead of
1971 SilcDList for requests, because it is faster. Affected file
1972 is lib/silcsftp/sftp_client.c.
1974 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1975 into lib/silccore/silcid.[ch].
1977 Renamed silcpayload.[ch] into silcargument.[ch].
1979 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * If client entry is deleted with active key agreement
1982 session, abort the session.
1984 The silc_client_abort_key_agreement now calls the completion
1985 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1987 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1990 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * Don't use __restrict in older GCC's. Affected file is
1993 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1995 * silc_net_localhost now attempts to reverse lookup the
1996 IP/hostname. Affected file lib/silcutil/silcnet.c.
1998 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1999 command. It can be used to gain founder privileges at
2000 the same time when joining the channel.
2002 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2003 kicker's client ID as well. Updated protocol specs.
2005 Defined that the server must send SILC_COMMAND_IDENTIFY
2006 command reply with error status to client who sent
2007 private message with invalid client ID.
2009 Updated the protocol specification.
2011 * Added silc_server_send_command_reply to send any
2012 command reply. Affected file silcd/packet_send.[ch].
2014 * Added silc_id_payload_encode_data to encode ID payload
2015 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2017 * The server now send IDENTIFY command reply with error
2018 status if client ID in private message is invalid. Affected
2019 file silcd/packet_receive.c.
2021 * Save the server key file with server's IP address in
2022 the filename instead of hostname. The affected file is
2023 irssi/src/silc/core/client_ops.c.
2025 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2030 * Added libtool support for compiling shared objects in
2031 lib/silcsim. Affected file configure.in.pre and
2032 lib/silcsim/Makefile.am. Original patch by cras.
2034 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2036 * Pid file configuration, and server's config file fixes
2037 patch by toma. Updated CREDITS file.
2039 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2041 * Fixed silc_client_channel_message to not try to decrypt
2042 the message twice if it resolved the destination client
2043 information. This could cause of dropping one channel
2044 message. Affected file lib/silcclient/client_channel.c.
2046 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2049 lib/silcclient/client.c. This function is used when the SILC
2050 Client is run under some other scheduler, or event loop or
2051 main loop. On GUI applications, for example this may be
2052 desired to used to run the client under the GUI application's
2053 main loop. Typically the GUI application would register an
2054 idle task that calls this function multiple times in a second
2055 to quickly process the SILC specific data.
2057 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2059 * Fixed silc_server_drop() for dropping the supplementary
2060 groups as well, this could cause a security hole on some
2063 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2068 * Write PID file after dropping privileges. Added -F option
2069 to run server on foreground. A patch by debolaz.
2070 Affected files silcd/server.c, silcd/silcd.c.
2072 * Fixed MOTD to return the MOTD file server name. Affected
2073 file silcd/command.c.
2075 * Added INFO command reply handling to the Irssi SILC Client.
2076 Affected file irssi/src/silc/core/client_ops.c.
2078 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Fixed the silc_idcache_list_* routines to really support
2081 the dynamic list. Fixes a crash. Affected file is
2082 lib/silccore/silcidcache.c.
2084 * Fixed the LIST command reply to really call LIST command's
2085 pending callbacks. Affected file silcd/command_reply.c.
2087 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * Update conn->local_entry->nickname after giving NICK
2090 command. Affected file lib/silcclient/command.c.
2092 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2094 * Added the [pid] option to the silcd configuration file
2096 Affected files: serverconfig.[ch] and silcd.c
2098 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Save fingerprint in WHOIS command reply in server.
2101 Affected file silcd/command_reply.c.
2103 * Fixed NICK commands pending callback registration.
2104 Affected file lib/silcclient/command.c.
2106 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Use ++server->cmd_ident when sending commands in server,
2109 instead of random number. Affected file silcd/command.c.
2111 * Fixed GETKEY command reply to call actually GETKEY pending
2112 command callbacks. Affected file silcd/command_reply.c.
2114 * A bit stricter check for nicknames. Check for same nickname
2115 in NICK command also. Affected file silcd/command.c.
2117 * Do not call INFO command everytime client ID changes, only
2118 during first connecting. Affected file lib/silcclient/client.c.
2120 * Set the new nickname only after successful command reply for
2121 NICK command is returned by server. Affected file
2122 lib/silcclient/command.c.
2124 * Remove nicknames from nicklist during server_signoff notify.
2125 Should fix /NAMES bit more. The affected file is
2126 irssi/src/silc/core/silc-channels.c.
2128 * Added `fingerprint' field to the SilcIDListData in the
2129 silcd/idlist.h to hold the fingerprint of the client's
2132 Send the fingerprint of the client's public key in WHOIS
2135 Affected files silcd/command.c, and silcd/idlist.[ch].
2137 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2138 create fingerprint from given data.
2140 * Show the fingerprint of the client's public key in WHOIS.
2141 Affected files irssi/src/module-formats.[ch] and
2142 irssi/src/silc/core/client_ops.c.
2144 * Format the multiple same nicknames also during JOIN and
2145 NICK_CHANGE notifys. Affected file is
2146 lib/silcclient/client_notify.c.
2148 * Do not print error on screen for invalid private message
2149 payload since it can come if someone is sending private
2150 messages with wrong key. Affected file
2151 lib/silccore/silcprivate.c.
2153 * Fixed multiple concurrent /PING crash. Affected file
2154 lib/silcclient/command.c.
2156 * Changed the wrong ID encoding. All IP addresses must be
2157 in MSB first order in encoded format. They were encoded
2158 wrong and was in LSB format. Affected files are
2159 silcd/serverid.c, lib/silcutil/silcutil.c.
2161 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2163 * Call the `connect' client operation through the scheduler
2164 in case of error. Affected file lib/silcclient/client.c.
2166 * Call the `failure' client operation even if the error
2167 occurred locally during a protocol. Affected file is
2168 lib/silcclient/protocol.c.
2170 * Added support of sending LIST command to router from normal
2171 server. This way normal server can get list of all channels
2172 in the network too. Fixed the channel list sending in the
2173 server too. Affected files are silcd/command.c, and
2174 silcd/command_reply.[ch].
2176 * Added silc_server_update_channels_by_server and
2177 silc_server_remove_channels_by_server. They are used during
2178 disconnection of primary router and in backup router protocol.
2179 Affected file silcd/server_util.[ch], silcd/server.c and
2180 silcd/server_backup.c.
2182 * Fixed channel adding to global list in IDENTIFY command
2183 reply in server. Affected file silcd/command_reply.c.
2185 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * If the incoming packet type is REKEY or REKEY_DONE process
2188 that packet always synchronously. Fixes yet another MAC
2189 failed error on slow (dialup) connections. Affected file
2190 lib/silcclient/client.c and silcd/server.c.
2192 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2194 * Call check_version SKE callback for initiator too. Affected
2195 file lib/silcske/silcske.c.
2197 * Implemented fix for security hole found in the SKE that was
2198 fixed in the specification few days back; the initiator's
2199 public key is now added to the HASH value computation.
2200 Added backwards support for the old way of doing it too, for
2201 old clients and old servers. Affected file is
2202 lib/silcske/silcske.c.
2204 * Enabled mutual authentication by default in SKE. If initiator
2205 is not providing mutual authentication the responder will
2206 force it. This will provide the proof of posession of the
2207 private key for responder. The affected files are
2208 lib/silcclient/protocol.c and silcd/protocol.c.
2210 * Do not cache anymore the server's public key during SKE.
2211 We do mutual authentication so the proof of posession of
2212 private key is done, and if the server is authenticated in
2213 conn auth protocol with public key we must have the public
2214 key already. Affected file silcd/protocol.c.
2216 * Added new global debug variable: silc_debug_hexdump. If
2217 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2218 file lib/silcutil/silclog.[ch].
2220 * Fixed compilation warning due to char * -> const char *.
2221 Affected files lib/silcutil/silcnet.h, and
2222 lib/silccore/silcauth.[ch].
2224 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Fixed CMODE command when new channel key was created. If
2227 the creation failed the old key was removed. Next time giving
2228 same command would crash the server since the old key was
2229 freed already. Affected file silcd/command.c.
2231 * Fixed the silc_server_announce_get_channels to not crash
2232 on reconnect. Affected file silcd/server.c.
2234 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Added silc_log_set_debug_string function to set a regex
2237 string to match for debug output. Only the function names,
2238 or filenames matching the given debug string is actually
2239 printed. This way it is possible to filter out those debug
2240 strings that user is not interested in.
2242 Fixed a bug in silc_string_regexify.
2244 Affected files lib/silcutil/silclog.[ch], and
2245 lib/silcutil/unix/silcunixutil.c.
2247 * Changed the -d options in both server and Irssi SILC client
2248 to take the debug string as argument. Affected files
2249 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2251 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Added silc_hash_babbleprint to create a Bubble Babble
2254 Encoded fingerprint. The encoding is developed by Antti
2255 Huima (draft-huima-babble-01.txt), and it creates human
2256 readable strings out of binary data. Affected file
2257 lib/silccrypt/silchash.[ch].
2259 * Print the babble print now in addition of fingerprint as well
2260 in Irssi SILC client. Affected files are
2261 irssi/src/fe-common/silc/module-formats.[ch],
2262 irssi/src/fe-common/silc/core/client_ops.c.
2264 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Fixed a security problem found in SKE. The initiator's
2267 public key too is now added to the HASH hash value creation
2268 which is signed by the responder to create the SIGN value.
2269 This will prevent anyone in the middle to lie to the responder
2270 about the initiator's public key. If this is done now, the
2271 man in the middle will get caught. Updated the protocol
2274 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Better installation directory handling. Configure module
2277 paths and other paths automatically to example_silc* files
2278 in doc/. A patch by toma.
2280 * Fixed compiler warning from MPI library, and from SILC RNG.
2283 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2284 It can be configured with ./configure. A patch by toma.
2286 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Find correct make to use in prepare-clean. A patch by
2289 toma. Affected file prepare-clean.
2291 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2293 * Added irssi variables use_auto_addr, auto_bind_ip,
2294 auto_bind_port and auto_public_ip.
2296 * Changed the interface for silc_client_send_key_agreement
2297 in lib/silcclient/silcapi.h
2301 irssi/src/silc/core/silc-core.c
2303 lib/silcclient/silcapi.h
2304 irssi/src/silc/core/silc-channels.c
2305 lib/silcclient/client_keyagr.c
2308 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Added silc_pkcs_public_key_compare to compare two
2311 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2313 * Check that the client who set the founder mode on the
2314 channel is the same client that is giving the founder
2315 mode to itself. It is done by comparing the saved public
2316 key (it is saved even in the authentication is passphrase).
2317 Affected file silcd/command.c.
2319 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Do not process packet for disconnected socket connection.
2322 Affected file lib/silccore/silcpacket.c.
2324 * Process the DISCONNECT packet through scheduler in the
2325 client library. Affected file lib/silcclient/client.c.
2327 * Fixed the silc_client_packet_parse to not to increase
2328 the packet sequence number if the conn->sock and the
2329 current socket connection is not same. This can happen
2330 for example during key agreement when the conn includes
2331 multiple socket connections (listeners). Affected file
2332 lib/silcclient/client.c.
2334 * The sender of the file transfer request now provides also
2335 the pointer (listener) for the key exchange protocol. If
2336 the listener cannot be created then it sends empty key
2337 agreement and lets the receiver provide the listener.
2339 Added `local_ip' and `local_port' arguments to the
2340 silc_client_file_send. If they are provided they are used,
2341 if not then it will attempt to find local IP address, if
2342 not found or bind fails then the remote client will provide
2345 Affected files are lib/silcclient/client_ftp.c and
2346 lib/silcclient/silcapi.h.
2348 * Extended the FILE SEND command to support defining the
2349 local IP and port for key exchange listener. They are
2350 optional. Affected file irssi/src/silc/core/silc-servers.c.
2352 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Defined to WHOIS command reply the sending of fingerprint
2355 of the client's public key (if the proof of posession of the
2356 corresponding private key is verified by the server).
2357 Updated to the protocol specification.
2359 * Added support of receiving the client's public key's
2360 fingerprint in command reply in client library. Affected
2361 file is lib/silcclient/command_reply.c, and
2362 lib/silcclient/idlist.[ch].
2364 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Do not send over 128 chars long nickname to the server
2367 in NICK command. Affected file lib/silcclient/command.c.
2369 * Do not send over 256 chars long channel names to the server
2370 in JOIN command. Affected file lib/silcclient/command.c.
2372 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Assure that silc_server_close_connection cannot be called
2375 twice for same socket context. Affected file is
2378 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Send error message to application if opening file for
2381 writing during file transfer fails. Affected file is
2382 lib/silcclient/client_ftp.c.
2384 Remove all file transfer sessions for a client that we're
2385 removing from ID cache.
2387 Affected file is lib/silcclient/client_ftp.c.
2389 * Fixed silc_net_addr2bin to return correct address. Affected
2390 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2392 * Fixed file transfer session removing on signoff notify.
2393 Affected file irssi/src/silc/core/silc-servers.c.
2395 * Added the SilcClientFileError to be returned in the monitor
2396 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2397 Affected file lib/silcclient/silcapi.h.
2399 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2401 * Fixed a crash in silc_client_ftp_free_sessions and
2402 silc_client_ftp_session_free_client. Affected file
2403 lib/silcclient/client_ftp.c.
2405 * Added `disabled' field in the SilcChannelEntry in the server
2406 to indicate if the server entry is disabled. Affected file

2416 * Fixed a crash in client resolving in client_prvmsg.c in
2417 client library. Affected file lib/silcclient/client_prvmsg.c.
2419 * Do not actually remove the client directly from ID cache
2420 during SERVER_SIGNOFF, but invalidate it. This way we
2421 preserve the WHOWAS info for the client. Affected file
2422 silcd/server_util.c.
2424 * Fixed SERVER_SIGNOFF notify handling in the server. The
2425 server is now able to process incoming SERVER_SIGNOFF notify
2426 for a server that it doesn't even know about. It will remove
2427 the clients provided in the notify. Affected file
2428 silcd/packet_receive.c.
2430 * Check for partial packet in data queue after every packet that
2431 was found from the queue. Return and wait for more data if
2432 there is partial data in queue. Affected file is
2433 lib/silccore/silcpacket.c.

2441 lib/silcclient/client_ftp.c.
2443 * Check that newsize in silc_buffer_realloc is larger than
2444 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2446 * Added better monitor of file transfers. It now monitors
2447 key agreement protocol during the file transfer too. Added
2448 error reporting too. Affected files
2449 irssi/src/silc/core/silc-servers.c,
2450 irssi/src/fe-common/silc/module-formats.[ch].
2452 * Wrote a help file for FILE command.
2454 * Added silc_rng_global_get_byte_fast to get not-so-secure
2455 random data as fast as possible. Random data is read from
2456 /dev/urandom if available and from the SILC RNG if not
2457 available. It is used in padding generation. Affected file
2458 lib/silccrypt/silcrng.[ch].
2460 * All packets in client library are now processed synchronously.
2461 Optimized packet processing a lot. Affected file
2462 lib/silcclient/client.c.
2464 * All server connection packets are processing synchronously
2465 now in server, to optimize packet processing. Affected file
2468 * Include files are installed now only in Toolkit distribution
2469 if make install is given. Affected files: all Makefile.am's.
2471 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Assure that silc_client_notify_by_server_resolve does not
2474 resolve the client information multiple times. If it cannot
2475 be found by the first it cannot be found at all. Affected
2476 file lib/silcclient/client_notify.c.
2478 * Fixed WHOWAS command reply calling. Affected file
2479 lib/silcclient/command_reply.c.
2481 * Removed all references to silc_idlist_get_client from the
2482 Irssi SILC client since that call is internal call used by
2483 the library. The Irssi SILC client will use now client
2484 retrieval functions found in silcapi.h.
2486 * Fixed a bug in resolving nickname info before sending
2487 private message. It used freed memory. Affected file
2488 irssi/src/silc/core/silc-servers.c.
2490 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2492 * Assure my_channels statistics cannot go negative in server.
2493 Affected files silcd/server.c, silcd/server_util.c.
2495 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2509 * Added silc_net_localip to return local host's IP address.
2510 Affected file lib/silcutil/silcnet.[ch].
2512 * If key exchange or rekey protocol is active for a connection
2513 parse all packets syncronously since there might be packets
2514 in packet queue that we are not able to process without first
2515 processing packets before them. Affected file silcd/server,
2516 lib/silcclient/client.c.
2518 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2519 whether library should continue processing the packet.
2520 Affected file lib/silccore/silcpacket.h.
2522 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2551 lib/silcutil/silcutil.[ch].
2553 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2555 * Resolve the client info when received private message or
2556 channel message for a client which nickname we don't know.
2557 Affected files lib/silcclient/client_prvmsg.c and

2566 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2567 is incomplete and is being resolved, it won't be resolved
2570 Make sure also that USERS command reply does not resolve
2571 twice information. Affected file is
2572 lib/silcclient/command_reply.c.
2574 Make sure that silc_client_get_clients_by_list does not
2575 resolve twice same information.
2577 * Check for valid client->id in the silc_server_free_client_data.
2578 Affected file silcd/server.c.
2580 * Fixed /GETKEY nick@server not to crash if the server entry
2581 is not found. Affected file lib/silcclient/command.c.
2583 * Fixed the silc_server_check_cmode_rights to check the

2589 Affected file silcd/command.c.
2591 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Call the silc_server_udpate_servers_by_server in the
2594 primary router that comes back online in the backup resuming
2595 protocol. Otherwise it routes packets wrong. Affected file
2596 silcd/server_util.[ch], silcd/server_backup.c.
2598 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2601 lib/silcutil/silcbuffmt.[ch].
2603 * Redefined the SILC packet header to include the padding
2604 length. Affected file lib/silccore/silcpacket.[ch].
2606 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2607 length for maximum padding up to 128 bytes). Affected
2608 file lib/silccore/silcpacket.h.
2610 * Removed all backwards support for old 0.5.x MAC thingies.
2611 The SILC packet header change makes it impossible to be
2612 backwards compatible.
2614 * Send the ENDING packet with timeout in the backup resuming
2615 protocol. This is to assure that all routers has connected
2616 to the primary router. Affected file silcd/server_backup.c.
2618 * Changed the RNG to take the first IV from random data. It
2619 used to take it from zero actually. Changed the RNG also
2620 to use /dev/urandom during session. /dev/random is used
2621 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2623 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2625 * Changed the SILC packet header to have the first two bytes
2626 (the packet length) encrypted. Affected files aroung the
2627 code tree, lib/silccore/silcpacket.[ch]. Removed the
2628 SilcPacketCheckDecrypt callback. It is not needed anymore
2629 since the silc_packet_receive_process will determine now
2630 whether the packet is normal or special.
2632 * Implemented the unidirectional MAC keys. Affected files
2633 lib/silcske/silcske.c, silcd/protocol.c and
2634 lib/silcclient/protocol.c.
2636 * Implemented the packet sequence number to the MAC computation.
2637 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2638 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2639 lib/silcclient/protocol.c.
2641 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Allow backup router to announce servers. All servers
2644 announced by backup router are added to the global list
2645 automatically. Update hte server's socket to our primary
2646 router also when backup router announces a server.
2647 Affected file silcd/packet_receive.c.
2649 * Do not update the client->router in the function
2650 silc_server_udpate_clients_by_server if the client is on
2651 global list. We might fail to find any specific server
2652 for locally connected clients and local cell clients. They
2653 should still use the `from' and not `to' as client->router.
2654 This fixes backup router resuming protocol. Affected file
2655 silcd/server_util.c.
2657 * Decrease channel statistics count only if the channel
2658 deletion worked. Affected files are silcd/server.c and
2659 silcd/server_util.c.
2661 * Added silc_server_update_servers_by_server to update origin
2662 of all server entries. Used during backup router protocol.
2663 Affected files silcd/server_util.[ch], silcd/server.c. and
2664 silcd/backup_router.c.
2666 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2667 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2668 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2669 lib/silccrypt/silchmac.c.
2671 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Assure that router cannot reroute the same channel message
2674 to the sender. Affected file silcd/packet_receive.c.
2676 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Made better checks that the channel message is not sent
2679 to the router it came from. Affected file is
2680 silcd/packet_send.c. Fixed memory leak too.
2682 * Announce informations for incoming router connection, but
2683 only after checking if it is replaced by backup router.
2684 Affected file silcd/packet_receive.c.
2686 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Fixed the backup resuming protocol to work in multiple
2689 router environment. Affected file silcd/server_backup.c.
2691 * Route packet only to one router in the function
2692 silc_server_packet_send_to_channel. Affected file is
2693 silcd/packet_send.c.
2695 * Fixed silc_server_send_notify_dest to set the broadcast
2696 flag. Fixed the silc_server_send_notify_topic to actually
2697 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2698 Affected file silcd/packet_send.c.
2700 * Changed the SFTP Filesystem interface. Changed the
2701 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2702 the filesystem operation function. The SilcSFTPFilesystem
2703 is now a context that is allocated by all filesystem allocation
2704 functions and it already includes the operations structure
2705 and filesystem specific context. It is given as argument
2706 now to the silc_sftp_server_start. This made the interface
2707 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2708 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2710 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2712 * Changed the backup router adding and getting interfaces
2713 in the server. The router that will be replaced by the
2714 specified backup router is now sent as argument. Affected
2715 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2718 * Added silc_net_addr2bin_ne to return the binary form of
2719 the IP address in network byte order. Affected files
2720 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2722 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Check for existing server ID in silc_server_new_server
2725 and in silc_server_connect_to_router_final and remove the
2726 old entry if it exists. Affected file silcd/packet_receive.c,
2729 * Send the channel message always to only one router, either
2730 in upstream or downstream. Affected file is
2731 silcd/packet_send.c.
2733 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Wrote the definition of the backup resuming protocol to the
2736 protocol specification.
2738 * Removed one redundant channel key generation from normal
2739 server during joining procedure. Removed one redundant
2740 channel key sending from server to router during joining
2741 procedure. Affected file silcd/command.c.
2743 * Made minor bugfixes to the backup router resuming protocol.
2744 Affected file silcd/server_backup.c, server.c.
2746 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * Added --disable-asm configuration option. Affected files
2749 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2752 * Implemented the backup resuming protocol that is used to
2753 resume the primary router position in the cell after the
2754 primary router comes back online. Affected files
2755 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2756 and silcd/server_util.[ch].
2758 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Sleep two (2) seconds after sending QUIT command to server.
2761 Affected file lib/silcclient/command.c.
2763 * Assure that if outgoing data buffer is pending do not force
2764 send any data. Affected file silcd/packet_send.c.
2766 * Assure that if outgoing data buffer is pending do not force
2767 send any data. Affected file lib/silcclient/client.c.
2769 * Implemented the backup router support when the primary router
2770 goes down. The servers and routers can now use the backup
2771 router as new primary router without loosing connectivity.
2773 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2775 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2776 in the server to indicate disabled entry. All data read
2777 from the connection will be ignored and no data is sent
2778 for entry that is disabled. Affected files are
2779 silcd/idlist.h, silcd/server.c.
2781 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Created SFTP client and server test programs in the
2784 lib/silcsftp/tests directory.
2786 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Implemented memory filesystem (virtual filesystem) for
2789 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2792 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Implemented the SFTP (SSH File Transfer Protocol) to the
2795 lib/silcsftp. It includes SFTP client and SFTP server
2798 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * Moved lib/silccore/silcprotocol.[ch] to the
2801 lib/silcutil library.
2803 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2804 take variable argument list pointer as argument. Affected
2805 file lib/silcutil/silcbuffmt.[ch].
2807 * Added silc_buffer_set function that is used to set data
2808 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2809 Affected file lib/silcutil/silcbuffer.h.
2811 * Changed various routines in the core library to use the new
2812 silc_buffer_set instead of allocating new buffer only for
2815 * Added 64-bit value formatting and unformatting support to the
2816 silc_buffer_[un]format routines. Affected file is
2817 lib/silcutil/silcbuffmt.[ch].
2819 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2820 to includes/bitmove.h.
2822 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2824 * Fixed channel user mode saving in client library. Affected
2825 file lib/silcclient/command[_reply].c.
2827 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Defined the file transfer to the SILC Protocol. Added
2830 new packet type SILC_PACKET_FTP and defined File Transfer
2831 Payload. The mandatory file transfer protocol is SFTP
2832 (SSH File Transfer Protocol). Affected file in addition
2833 of the internet draft is lib/silccore/silcpacket.h.
2835 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2836 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2837 is used as part of backup router protocol when the primary
2838 router of the cell is back online and wishes to resume
2839 the position as primary router.
2841 * Redefined the MAC generation keys in the protocol. The
2842 same key is not used anymore in both direction. Both
2843 direction will now use different keys for sending and
2844 receiving. This fixes a potential security flaw. This
2845 change causes incompatibilities in the protocol.
2847 * Redefined also the MAC computation from the packet.
2848 An packet sequence number is now added to the MAC
2849 computation. This prevents possible replay attacks against
2850 the protocol. This change too causes incompatibilities
2853 Added `sequence' field to the SilcPacketContext to hold
2854 the current sequence number for the packet.
2856 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Added `created' field to the SilcIDListData in the file
2859 silcd/idlist.h to indicate the time when the entry was
2862 * Added `created' field to the SilcChannelEntry too. Affected
2863 file silcd/idlist.h.
2865 * Added `creation_time' aguments to all the announcement functions
2866 in the server. If it is provided then only the entries that
2867 was created after the provided time frame are actually
2868 announced. Affected file silcd/server.[ch].
2870 * The protocol says that the Channel ID's IP address must be
2871 based on the router's IP address. Added check for this in
2872 the silc_server_new_channel when processing incoming New Channel
2873 Payload. Affected file silcd/packet_receive.c.
2875 * Print out the correct version with --version in SILC client.
2876 Affected file irssi/src/silc/core/silc-core.c.
2878 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Fixed WHOWAS command to check for completnes of the client
2881 entry always, not just when the command is coming from client.
2882 Affected file silcd/command.c.
2884 * Added new function silc_server_packet_queue_purge to purge the
2885 outgoing data queue to the network. After the function returns
2886 it is guaranteed that the outgoing packet queue is empty.
2887 Affected file silcd/packet_send.[ch].
2889 * Purge the outgoing packet queue in the rekey protocol's final
2890 callback to assure that all rekey packets go to the network
2891 before quitting the protocol. Affected file silcd/server.c.
2893 * Added silc_client_packet_queue_parse as similar function as
2894 in server to the client library. The affected file is
2895 lib/silcclient/client.c.
2897 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Splitted silcd/server.c and created silcd/server_util.[ch]
2900 for utility functions.
2902 * Added new socket flag SILC_SF_DISABLED to indicate that the
2903 connection is open but nothing can be sent to or received from
2904 the connection. Affected file lib/silcutil/silsockconn.[ch].
2905 The checking for disabled socket is checked in the low level
2906 silc_socket_write and silc_socket_read functions.
2908 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Allow only nicknames and channel names that fits into the
2911 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2913 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * When processing JOIN command reply in server check that if
2916 the channel exists in our global list we'll move it the local
2917 list. Affected file silcd/command_reply.c.
2919 * Fixed the check whether client is joined on the channel already
2920 in JOIN command. Affected file lib/silcclient/command.c.
2922 * Fixed the JOIN command reply to check whether the channel
2923 already exists. Affected file lib/silcclient/command_reply.c.
2925 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Added silc_ske_status_string to map the SKE error numbers
2928 to readable strings. The affected files are
2929 lib/silcske/silcske[_status].[ch].
2931 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Do not show the private channels on the WHOIS channel list
2934 as it is not allowed by the protocol. The affected file is
2937 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Assure that the packet length digged from the actual packet
2940 is something sensible in the silc_packet_decrypt_rest_special
2941 in lib/silccrypt/silcpacket.c.
2943 * Free and NULL the allocated pointer in silc_hmac_alloc if
2944 the HMAC allocation fails. The affected file is
2945 lib/silccrypt/silchmac.c.
2947 * Print the selected security properties to the log files in
2948 the server. Affected file silcd/protocol.c.
2950 * Add SKE's reference counter even if calling the completion
2951 callback manually. Otherwise it goes negative, although it
2952 does not cause any problems. The affected file is
2953 lib/silcske/silcske.c.
2955 * Remove the client entry with short timeout after giving the
2956 KILL command. Affected file lib/silcclient/command.c.
2958 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2959 case all found clients are already disconnected (WHOWAS would
2960 found them) in the server. Affected file silcd/command.c.
2962 * Update the last_receive (time of last data received) to be
2963 updated only when received private or channel message so that
2964 the idle time showed in WHOIS makes more sense.
2966 * Added boolean field `valid' in to the SilcClientEntry in the
2967 client library to indicate whether the entry is valid or not.
2968 This fixes the nickname change bug on channel when changing
2969 the nickname to be same than the old (like nick to Nick) the
2970 nickname formatter doesn't set the new nick anymore to Nick@host.
2971 Affected file lib/silcclient/idlist.[ch].
2973 * Now actually fixed the nickname changing on disconnection.
2974 Added new function silc_change_nick to the Irssi SILC Client.
2975 Affected file irssi/src/silc/core/client_ops.c,
2976 irssi/src/silc/core/silc-nicklist.[ch].
2978 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Check that the public key exists in the GETKEY command before
2981 trying to encode it. Affected file silcd/command.c.
2983 * Print some notifications on received public keys with GETKEY
2984 command in the Irssi SILC Client. Affected files are
2985 irssi/src/fe-common/silc/module-formats.[ch],
2986 irssi/src/silc/core/client_ops.c.
2988 * Use IDENTIFY command to resolve the server information in the
2989 GETKEY command instead of INFO command. Affected file
2990 lib/silcclient/command.c.
2992 * All command reply functions in the client library now calls
2993 the pending command reply callbacks even if an error has
2994 occurred. The server has done this a long time and now it was
2995 time to move the client library to this as well. Now all
2996 errors can be delivered back to the pending command reply
2997 callbacks if necessary. Affected files are
2998 lib/silcclient/command[_reply].[ch].
3000 * Change the nickname on disconnection back to the username
3001 because in reconnect the server will enforce it to it anyway.
3002 Affected file irssi/src/silc/core/silc-servers.c.
3004 * Fixed a config file parsing bug in the Irssi SILC client.
3005 Affected file irssi/src/silc/core/clientconfig.c.
3007 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * When printing the channel mode on JOIN, verify that the
3010 channel key and channel's HMAC are valid. Affected file
3011 irssi/src/silc/core/client_ops.c.
3013 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3016 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3017 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3019 * Removed channel key rekey task deleting from the function
3020 silc_server_save_channel_key. Affected file silcd/server.c.
3021 Added explicit timeout task context instead that is used to
3022 delete the task if we are registering a new task before the
3023 new task has elapsed.
3025 * When channel key rekey occurs the client library now saves
3026 the old channel key for a short period of time (10 seconds) and
3027 is able to use it in case some is still sending channel
3028 messages encrypted with the old key after the rekey. Affected
3029 file lib/silcclient/[idlist.h|client_channel.c].
3031 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Added check to the silc_server_new_id_real to not accept
3034 new ID if it is the sender's own ID. Affected file is
3035 silcd/packet_receive.c.
3037 * Assure that we do not announce ourself or the one we've
3038 sending our announcements when we're router and are announcing
3039 servers to our primary router. Affected file silcd/server.c.
3041 * Fixed silc_server_command_identify_check_client to assemble
3042 correct WHOIS packet. It send corrupted WHOIS packet and
3043 caused problem with router to router connections. Affected
3044 file silcd/command.c.
3046 Fixed also silc_server_command_whois_check the same way
3047 as for the IDENTIFY command.
3049 * Added new SilcIDListStatus to the server in the SilcIDListData
3050 structure. The status now includes the current status of
3051 the entry (like registered, resolved etc.). Affected file
3052 silcd/idlist.[ch]. Defined a bunch of different status types
3053 as well. This replaced the old boolean registered field as well.
3055 Added resolve_cmd_ident field to the SilcClientEntry structure
3056 too so that if the entry is for example being resolved so
3057 another command may attach to the same pending command reply
3058 without requiring to resolve the same entry again. This concept
3059 should optimize the WHOIS and the IDENTIFY resolving under
3060 heavy load by taking away unnecessary resolving for entries
3061 that are being resolved already.
3063 Added support for adding multiple pending commands for one
3064 command idenfier. Affected file silcd/command[_reply].[ch].
3066 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3067 before deleting the data. Otherwise the hash table will have
3068 freed data in comparison functions. Affected file is
3069 silcd/command_reply.c.
3071 * Fixed silc_idlist_replace_client_id to add the new entry to
3072 the cache with NULL nickname. Otherwise there will be invalid
3073 memory as the nickname after the nickname is freed. Affected
3074 file silcd/packet_receive.c.
3076 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3077 saved into wrong slots because the previous number of entries
3078 was not taken into account. Affected file silcd/idlist.c.
3079 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3081 * If we are router and we receive JOIN notify to a channel that
3082 does not have any users then notified client is marked as the
3083 channel founder, as it is it. The affected file is
3084 silcd/packet_receive.c
3086 * Added to the extended hash table API's table_del_*ext functions
3087 the destructor as argument too, so that the caller can decide
3088 which destructor to use or whether to use destructor at all.
3089 Affected file lib/silcutil/silchashtable.[ch].
3091 * Fixed ID Cache purging. It actually deleted the entries from
3092 the hash table after the data was freed. The hash table ended
3093 up comparing freed memory. The affected file is
3094 lib/silccore/silcidcache.c.
3096 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Fixed Irssi SILC client's KILL command's HELP syntax.
3100 * The USERS command now resolves the detailed user information
3101 if the userinfo field is missing. Affected file is
3102 lib/silcclient/command_reply.c.
3104 * Do not print error in silc_file_read if the read file does
3105 not exist. Just silently return NULL. Affected file is
3106 lib/silcutil/silcutil.c.
3108 * Fixed the silc_log_output to not wine about NULL filename
3109 and to not create some bogus " " filename. Affected file is
3110 lib/silcutil/silclog.c.
3112 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Fixed various printing bugs on the user interface in the
3115 Irssi SILC Client. Minor changes that were forgotten from
3118 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Fixed the configure.in.pre and the compilation and distribution
3121 environment to support the new autoconf 2.52. That version is
3122 now required to compile the CVS trunk.
3124 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3127 to generally parse user@fqdn format strings. Affected file
3128 lib/silcutil/silcutil.c.
3130 * Added nickname_format and nickname_force_format fields to the
3131 SilcClientParams structure. The first one defines the format
3132 for the nicknames that the library will enforce if the receives
3133 multiple same nicknames. The second one is boolean value and
3134 can be used to force the library to always enforce the format
3135 to the nicknames regardles whether there are multiple nicknames
3136 or not. This configurable formatting was employed to flexibly
3137 support accessing multiple nicknames from the user interface.
3138 The userinterface can now set the nicknames to what ever format
3139 they prefer. Affected file lib/silcclient/silcapi.h.
3141 Added function silc_client_nickname_format to the file
3142 lib/silcclient/idlist.c. It performs the nickname formatting.
3144 Added new field `hostname´ to the SilcClientEntry context.
3145 It holds the hostname of the client. Affected file is
3146 lib/silcclient/idlist.h.
3148 * Irssi SILC Client sets the nicknames in nick@hostn format.
3149 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3150 irssi/src/silc/core/silc-core.c.
3152 The WHOIS printing now also shows both the real nickname and
3153 the formatted nickname so that user knows how to access the
3154 user if there are multiple same nicknames cached. Affected
3155 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3156 printing formatting too to take the hostname now as a separate
3157 argument. The Affected file is
3158 irssi/src/fe-common/silc/modules-formats.[ch].
3160 * Changed the silc_client_get_clients_local to accept the formatted
3161 nickname as argument. It accepts the real nickname too but the
3162 formatted nickname can be used to find the true entry from
3163 multiple entries. Affected file lib/silcclient/silcapi.h and
3164 lib/silcclient/idlist.c.
3166 * Added nickname_format_parse field to the SilcClientParams.
3167 It is a callback function provided by the application to parse
3168 the nickname out of the formatted nickname string. The library
3169 calls it to get the nickname from the formatted string. Since
3170 the application generally knows better the format of the nickname
3171 string it parses it instead of the library, even though library
3172 encodes the formatted string. If the callback function is not
3173 provided then the library will use the string as is. The
3174 affected file is lib/silcclient/silcapi.h.
3176 * All the nickname strings passed to the client library in
3177 commands are now expected to be formatted nickname strings.
3178 If the command does not support the formatted nickname string
3179 it will assume that the sent string is the actual nickname.
3180 Affected file lib/silcclient/command.c.
3182 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Added public key authentication support to OPER and SILCOPER
3185 commands in the client library. Affected file is
3186 lib/silcclient/command.c.
3188 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Changed the get_auth_methdod client operation to be asynchronous.
3191 It can be async if the application resolves the authentication
3192 method from the server during the negotiation. Added new
3193 SilcGetAuthMeth completion callback that the application will
3194 call after resolving the authentication method.
3196 Added function silc_client_request_authentication_method that
3197 the application can use to resolve the authentication method
3198 from the server. Added also SilcConnectionAuthRequest callback
3199 that the library will call after the server has replied. The
3200 application can call this function if it does not know the
3201 current authentication method.
3203 Affected files are lib/silcclient/client.c and
3204 lib/silcclient/silcapi.h.
3206 * The Irssi SILC client now automatically resolves the authentication
3207 method incase any configuration information is not present (and
3208 currently there never is). The affected file is
3209 irssi/src/silc/core/client_ops.c.
3211 * Fixed public key authentication from the client library.
3212 Affected file lib/silcclient/protocol.c. Changed also the
3213 protocol specification about the public key authentication in
3214 the connection authentication protocol. The actual data to be
3215 signed is now computed with a hash function before signing.
3217 * Fixed the public key authentication from the server as well.
3218 Affected file silcd/protocol.c.
3220 * Removed the mlock()'s from the memory allocation routines.
3221 Affected file lib/silcutil/silcmemory.c. The ./configure does
3222 not check anymore for the mlock(). Affected file is
3225 * Fixed USERS command in server to allow the execution of the
3226 command for private and secret channels if the client sending
3227 the command is on the channel. Affected file silcd/command.c.
3229 * Fixed silc_client_get_clients_local to return the clients
3230 count correctly. It could return wrong value. Affected file
3231 lib/silcclient/idlist.c.
3233 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3236 types. The assembler optimizations seemed not to like 64-bit
3237 data types. The assmebler optimizations thus are now enabled
3238 also for BSD systems as opposed to only enable them for Linux.
3240 * Do not check for threads at all on BSD systems. Affected
3241 file configure.in.pre.
3243 * Removed -n and -h options from the Irssi SILC Client since
3244 they are not used in silc.
3246 * Fixed the prime generation to assure that the first digit
3247 of the generated random number is not zero since our conversion
3248 routines does not like number strings that starts with zero
3249 digit. If zero digit is seen the random number is regenerated.
3250 This caused some corrupted RSA keys when the zero first digit
3251 was met. Affected file lib/silcmath/silcprimegen.c.
3253 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Fixed WIN32 configuration in the ./configure script.
3256 Fixed to include xti.h on environments that has it.
3257 Patches by Carsten Ilchmann and andrew.
3259 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Changed the silc_id_create_client_id to be collision
3262 resistant. It is now assured that there cannot be created
3263 two same client ID's. I suspect that some weird bugs in
3264 the server were actually caused by duplicate Client IDs.
3265 Affected file silcd/serverid.[ch]. A router receiving
3266 new ID now also assures and informs the sending server
3267 if the ID caused collision.
3269 * Changed the silc_id_create_channel_id to also assure that
3270 there are no collisions.
3272 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Statement about ignoring the Mutual Authentication flag when
3275 performing rekey with PFS was a bit misleading. It is ignored
3276 if it was set in the initial negotiation, it cannot be even
3277 set in the rekey. Fixed in the ke-auth draft. Started the
3278 new versions of the protocol drafts in the doc/.
3280 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Fixed a bug in silc_client_command_identify_save when saving
3283 new channel information. The channel name was no duplicated
3284 and caused crash on exit. Affected file is
3285 lib/silcclient/command_reply.c.
3287 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Fixed the getkey command handling in the server. Send just
3290 empty OK reply to the sender if the key could not be fetched
3291 (but everything else was ok, like the key just was not available).
3292 Changed the public key parameter to optional in the protocol
3293 specs so that empty OK reply can be sent. Affected file
3296 Added a message to Irssi SILC client to tell to user if the
3297 server did not return a public key.
3299 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Fixed a channel key regeneration bug. It registered new
3302 timeout tasks exponentially until all system resources were
3303 used. Affected file silcd/server.c.
3305 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Added the SILC Document generator to the scripts/silcdoc.
3308 It can be used to generate the Toolkit Reference Manual out
3309 of the source tree. Internally it will also use the RoboDoc
3310 generator now imported in util/robodoc.
3312 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Added couple of return's in rekey protocol if error orccurred
3315 during the protocol. The execution must be terminated.
3316 Affected file silcd/protocol.c. Also, terminate the protocol
3317 always with timeout.
3319 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * The client's Client ID was created initally from the wrong
3322 nickname (it could have been in format nick@host) in the
3323 silc_server_new_client. Affected file silcd/packet_receive.c
3325 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Added some SILC_LOG_ERROR's to various error conditions
3328 if client could not be added to ID cache. Affected files
3329 silcd/packet_receive.c and silcd/server.c.
3331 * When client's sock->user_data is freed, NULL also the
3332 client->router and client->connection pointers. Added check
3333 for these pointers being NULL to various places around the
3334 code. Affected file silcd/server.c.
3336 * Added client->data.registered == TRUE checks to various
3337 places around the code to assure that unregistered client's
3338 are not handled when it is not allowed. Affected file
3341 * Added `bool registered' fields to all
3342 silc_idlist_[server|client]_get_* routines to indicate whether
3343 the fetched client needs to be registered or not. Affected
3344 file silcd/idlist.[ch].
3346 * Add your own entry as registered to the ID cache in the
3347 server. Affected file server.c.
3349 * Fixed a bug in silc_server_new_server. The SilcServer was
3350 set as the new server's context instead of SilcServerEntry.
3351 This naturally caused some weird bugs.
3353 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Do not delete the channel rekey task when adding it
3356 for in silc_server_create_channel_key.
3358 * Changed the silc_server_create_channel_key to return
3359 TRUE or FALSE to indicate the success of the channel key
3362 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * Fixed MSVC++ project files and added missing files to
3365 Makefiles under win32/.
3367 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Do not add TCP_NODELAY flag if the operating system
3370 does not have it defined. Affected files are
3371 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3373 * Fixed buffer overflow from Irssi SILC Client. Affected
3374 file irssi/src/fe-common/core/themes.c.
3376 * Fixed double free in client library in the file
3377 lib/silcclient/client.c when disconnecting from server.
3379 * Applied double free patch from cras to Irssi SILC client.
3380 Affected files irssi/src/core/[modules/expandos].c
3382 * Fixed the disconnection handling to Irssi SILC Client.
3383 The application must call silc_client_close_connection
3384 in ops->connect client operation in case of failure of
3385 the connection. Affected file is
3386 irssi/src/silc/core/client_ops.c.
3388 * Do not set sock->protocol to NULL in the function
3389 silc_client_close_connection after executing the protocol's
3390 final callback since the sock might not be valid anymore.
3391 Affected file lib/silcclient/client.c.
3393 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Do not enable SILC_THREADS if the linking with libpthread
3396 did not happen. Affected file configure.in.pre.
3398 * Added notion to protocol specification that server must
3399 verify the sent authentication payload with CMODE when
3400 setting the channel founder key. Implemented it to the
3401 server. Affected file silcd/command.c.
3403 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Added _EXTRA_DIST SILC distribution variable to the
3406 distributions file. It is used to conditionally add extra
3407 files or directories to the specific distribution. Affected
3408 files ./prepare, Makefile.am.pre and distributions.
3410 Removed the `_' from the start of the distribution names.
3413 * Added README.WIN32 for instructions to compile the Toolkit
3416 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3418 * Fixed a double free in disconnection in the server. Affected
3419 file is silcd/server.c.
3421 * Fixed the lib/silcske/groups.c to work now also with GMP
3422 MP library. The string conversion did not work when using
3423 specific base and the base is indicated in the string as well.
3425 * Created win32/ directory which now includes MSVC++ specific
3426 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3427 It will appear only in the toolkit distribution
3429 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Changed the key material distribution function in case when
3432 the hash output is too short. The data is now concatenated
3433 a bit differently than it used to. Made the change to the
3434 SKE protocol specification.
3436 * Added better GMP detection to configure.in.pre. A patch
3439 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Fixed a minor bug in SKE that might cause some problem on
3442 some platforms. Affected file lib/silcske/silcske.c.
3444 * Added the cookie checking for initiator in the SKE. It checks
3445 that the responder returns the sent cookie unmodified. The
3446 affected file is lib/silcske/silcske.c. Added new SKE
3447 error type INVALID_COOKIE that can be sent during the
3448 negotiation. Fixed some memory leaks as well.
3450 * Added the "invalid cookie" error message to Irssi SILC client's
3453 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Added `task_max' field to the SilcClientParams to indicate
3456 the maximum tasks the scheduler can handle. If set to zero,
3457 default values are used. Affected file lib/silcclient/silcapi.h.
3459 * Fixed memory leaks in silc_client_close_connection. Affected
3460 file lib/silcclient/client.c.
3462 * Added silc_client_del_client_entry to client library to free
3463 all memory of given client entry. Affected file is
3464 lib/silcclient/idlist.[ch].
3466 * Added new functions silc_client_del_channel and
3467 silc_client_del_server to delete channel and server entries.
3468 Affected file lib/silcclient/[silcapi.h/idlist.c].
3470 * Removed silc_client_del_client_by_id from silcapi.h.
3472 * Fixed the INFO command to return the server's own info
3473 correctly when querying by Server ID. Affected file is
3476 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Removed the non-blocking settings in WIN32 code in the
3479 silc_sock_[read/write] and added SleepEx instead. Affected
3480 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3481 of input data is now checked with FIONREAD and ioctlsocket.
3483 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3485 * Call silc_schedule_task_del_by_context in the
3486 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3487 Affected file lib/silccore/silcprotocol.c.
3489 * Call silc_protocol_cancel for active protocols in the
3490 silc_server_close_connection if the funtion
3491 silc_server_free_sock_user_data has not been called.
3492 Affected file silcd/server.c.
3494 * Generic tasks cannot be deleted using the del_by_fd
3495 task deleting function since generic tasks does not match
3496 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3498 * Added a notion to SILCOPER help file that the SILCOPER works
3499 only on router server, not on normal server.
3501 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * Added for WIN32 support for the new scheduler as well.
3504 Affected file lib/silcutil/win32/silcwin32schedule.c.
3506 * Fixed the SHA1 implementation to work on various platforms.
3508 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3511 API. It is part of the scheduler now. Everything else is
3512 as previously but some functions has changed their names.
3513 Checkout the lib/silcutil/silcschedule.h for the interface.
3514 Updated all applications to use the new interface. Affected
3515 files are lib/silcutil/silcschedule.[ch].
3517 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3519 * Found a bug in the SKE implementation. The HASH value,
3520 specified by the protocol, was not computed correctly. The
3521 public key of the responder was not added to the computation
3522 even though it is mandatory. Affected file lib/silcske/silcske.c.
3523 This unfortunately causes incompatibilities with older
3524 clients and servers.
3526 * Added WIN32 specific network init and uninit functions:
3527 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3528 the Winsock2. Affected file lib/silcutil/silcnet.h and
3529 lib/silcutil/win32/silcwin32net.c.
3531 * Set the socket always to nonblocking mode on WIN32 after
3532 reading data or writing data. Affected file is
3533 lib/silcutil/win32/silcwin32sockconn.c.
3535 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Fixed various compilation problems under WIN32. Affected
3538 files lib/silcutil/win32/silcwin32thread.c and
3539 lib/silcutil/win32/silcwin32schedule.c.
3541 * Removed all _internal.h #includes from public header
3542 files. Internal headers must never be included from
3545 Removed also the lib/silcske/payload_internal.h file.
3547 * All include files that may be needed (public and some others
3548 included by the public headers) by application developers are
3549 now copied to the ./includes directory. It does not copy any
3550 internal headers. Affected file Makefile.defines.pre and all
3551 Makefile.am's under lib/ and subdirs.
3553 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Do not change the ~/.silc directory's permissions automatically.
3556 Affected file irssi/src/silc/core/clientutil.c.
3558 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Do not cancel the protocol in silc_server_close_connection
3561 it might cause recursion. Now cancelled in the function
3562 silc_server_free_sock_user_data. Affected file silcd/server.c.
3564 * Fixed the silc_server_remove_clients_by_server to regenerate
3565 the channel keys correctly finally. Added also new function
3566 silc_server_remove_clients_channels to actually do it.
3567 Affected file silcd/server.c.
3569 * Fixed the silc_server_new_channel to not crash by giving
3570 wrong router to the new channel. Affected file is
3571 silcd/packet_receive.c.
3573 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3575 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3576 which is given as argument to the silc_client_alloc now.
3577 It can be used to configure the client and set various parameters
3578 that affect the function of the client.
3580 * The USERS command in server did not check whether the channel
3581 is private or secret. Affected file silcd/command.c.
3583 * Added new argument to the USERS command in protocol specification.
3584 The USERS command now can take the channel name as argument
3585 as well. Added support for this in client and server and
3586 updated the protocol specs.
3588 * Completed the GETKEY command in client. It can be now used
3589 to fetch also servers public key not only some clients.
3590 Affected files lib/silcclient/command[_reply].c.
3592 * Added silc_client_get_server to return server entry by the
3593 server name. Affected files lib/silcclient/silcapi.h and
3596 * Redefined the IDENTIFY command in protocol specification to be
3597 more generic. It now can be used to query information about
3598 any entity in the SILC Network, including clients, servers and
3599 channels. The query may be based either the entity's name
3600 or the ID. Added support for this in both client and server.
3602 Affected files silcd/command.c and lib/silcclient/command.c
3603 and command_reply.c.
3605 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3606 the _from_client and _from_server functions. Affected file
3609 * Added silc_client_get_channel_by_id_resolve to the file
3610 lib/silcclient/silcapi.h to resolve channel information by
3611 its ID. Added also silc_client_get_channel_by_id that
3612 does not resolve it from the server.
3614 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Added SilcServerEntry context into the client library
3617 to represent one server. The INFO command now allocates
3618 these to save the resolved server info. For now on the
3619 client library will also keep information about servers,
3620 connected and resolved with INFO.
3622 The INFO command now allocates the SilcServerEntry context
3623 and saves the server info there. The COMMAND_REPLY in
3624 the INFO now returns the parameters to application in
3625 same order as defined in the protocol specification.
3627 The entries are cached in the client->server_cache.
3629 * The INFO command is now issued after received the Client ID
3630 from the server. Affected file lib/silcclient/client.c.
3632 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3633 to the application as the mode changer might be server.
3634 It is guaranteed that NULL is not returned anymore to the
3635 application. Affected file lib/silcclient/client_notify.c.
3637 The ID Type is now also passed to the application so that
3638 it can check whether the returned entry is SilcClientEntry
3641 Added new function silc_client_get_server_by_id to return
3642 the server entry by ID. Affected files are the
3643 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3645 * Do not create the channel in the Irssi SILC Client when issuing
3646 the JOIN command but when received the sucessful JOIN command
3647 reply. Otherwise the channel might get created even though we
3648 could not join it. The Affected file is
3649 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3651 * Fixed a channel joining bug in router. The router must also
3652 check the channel modes, invite and ban lists etc. when serving
3653 the JOIN command sent by normal server. Affected file is
3654 silcd/command.c. The router now resolves the client's
3655 information from the server who sent the JOIN command if it
3656 does not know it, and processes the JOIN command only after
3659 * Changed the SilcCommandCb to take new argument; void *context2.
3660 Affected file lib/silccore/silccommand.h
3662 The second argument in the command callbacks in the server now
3663 includes the SilcServerCommandReplyContext if the command was
3664 called as pending command callback from the command reply.
3665 Otherwise it is NULL. When called as pending the status of the
3666 command reply will be checked and if it was erronous the
3667 error will be sent to the original sender of the command.
3668 This way the client always receives the error messages even
3669 though the server was actually the one who received the error
3670 when it resent the command to router, for example. Affected
3671 files silcd/command[_reply].[ch].
3673 * Fixed sending WHOWAS command's error message to client if
3674 the requested client could not be found. It was missing.
3677 * Changed the CMODE and CUMODE commands reply arguments in the
3678 protocol specification. The Channel ID is now sent in both
3679 of the commands to identify the channel. Implemented this
3680 new feature to the client and server. Affected files
3681 lib/silcclient/command_reply.c and silcd/command.c.
3683 * Made better checks for invite and ban lists in the JOIN
3684 command in server. Affected file silcd/command.c.
3686 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * The server now performs the incoming host IP/DNS lookup
3689 using the silc_socket_host_lookup and thus does not block
3690 the server anymore. Affected file silcd/server.c.
3692 * Completed the multi-thread support for SILC Scheduler in
3693 the lib/silcutil/silcschedule.c.
3695 * Fixed the configure.in.pre to detect the pthread correctly
3698 * Fixed a deadlock in silc_task_queue_wakeup in the file
3699 lib/silcutil/silctask.c.
3701 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3703 * Added new function silc_schedule_wakeup that is used in
3704 multi-threaded environment to wakeup the main thread's
3705 schduler. It needs to be used when a thread adds a new task
3706 or removes a task from task queues. After waking up, the
3707 scheduler will detect the task queue changes. If threads
3708 support is not compiled in this function has no effect.
3709 Implemented the wakeup mechanism to both Unix and WIN32
3710 systems. Affected files are lib/silcutil/silcschedule.[ch],
3711 lib/silcutil/unix/silcunixschedule.c and the
3712 lib/silcutil/win32/silcwin32schedule.c.
3714 * Added new function silc_task_queue_wakeup to wakeup the
3715 scheduler by the specified task queue. Affected file
3716 lib/silcutil/silctask.[ch].
3718 * The silc_socket_host_lookup_start now wakes up the scheduler
3719 after adding the timeout task. Affected file is
3720 lib/silcutil/silcsockconn.c.
3722 * The silc_socket_host_lookup is synchronous now if the threads
3723 support is not compiled in. However, the callback is still
3724 called asyncronously through the scheduler, anyway. Affected
3725 file lib/silcutil/silcsockconn.c.
3727 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3729 * Added new function silc_socket_host_lookup to perform
3730 asynchronous IP and FQDN lookups for the socket connection.
3731 Affected files lib/silcutil/silcsockconn.[ch].
3733 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3735 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3736 that may or may not compile the mutex support in.
3738 Changed the silc_mutex_alloc interface. It allocates the
3739 mutex now to the sent pointer and returns TRUE or FALSE.
3741 Affected file lib/silcutil/silcmutex.h.
3743 * Wrote the SILC Task Queue interface to support multi-threads.
3744 Affected file lib/silcutil/silctask.[ch].
3746 * Wrote the SILC Scheduler to support multi-threads. Affected
3747 file lib/silcutil/silcschedule.c.
3749 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3751 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3752 in lib/silcutil/win32/.
3754 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3756 * Defined SILC Mutex API and SILC Thread API and implemented
3757 them for Unix. Affected files are
3758 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3759 lib/silcutil/unix/silcunixmutex.c and
3760 lib/silcutil/unix/silcunixthread.c.
3762 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Fixed the silc_server_remove_clients_by_server's channel
3765 key re-generation. The hash table handling was incorrect
3766 and would not work with many channels. Affected file is
3769 * Fixed some memory leaks around the server code.
3771 * Rewrote the silc_server_get_users_on_channel to support IPv6
3772 based Client ID's. Affected file silcd/server.c.
3774 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3775 specification. However, a separate document must be written
3776 to define the detailed signing procedure and the payload
3777 associated with the flag. Defined the flag to the
3778 lib/silccore/silcchannel.h as well.
3780 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Changed the dynamic tables to static size tables in the
3783 lib/silccrypt/silchmac.c.
3785 * Removed GCC dependencies from the code. A patch by cras.
3787 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3789 * Do not show the error "Error receiving packet bla bla"
3790 in server if it really was not an error (-2 means that reading
3791 is pending). Affected file silcd/server.c.
3793 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Fixed a possible crash in silc_server_remove_clients_by_server
3796 in silcd/server.c. Fixed there also some memory leaks.
3798 * Fixed the silc_idlist_replace_client_id. It could replace
3799 wrong key in the hash table. Affected file silcd/idlist.c.
3801 * Do not check whether there are global users on the channel
3802 if the channel->global_users is FALSE. Affected functions
3803 silc_server_remove_from_one_channel and
3804 silc_server_remove_from_channels in silcd/server.c. Also,
3805 do not check if the removed client is local as we can be
3806 sure that global client was not removed from the channel
3807 and checking for global users is not needed.
3809 * The silc_server_remove_clients_by_server now re-generates
3810 the channel keys correctly for those channels that had
3811 clients removed from them. Affected file silcd/server.c.
3813 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Found the reason of random crashes in the server. We weren't
3816 ignoring the SIGPIPE signal (which can be sent in write())
3817 and it crashed the server. Affected file silcd/silcd.c.
3819 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Assure that sock->user_data is not NULL in the function
3822 silc_server_packet_send in silcd/packet_send.c.
3824 * Disconnect the remote connection if it could not be added
3825 to any ID lists in the server. The affected file is
3828 * Check in silc_server_packet_send[_real/dest] that the
3829 socket is not disconnecting and ignore the data if it is.
3830 Affected file silcd/packet_send.c.
3832 * Define inline to __inline on native WIN32 compilation.
3833 Affected file includes/silcwin32.h.
3835 * Added some explicit type casts for inline code since MSVC
3836 require them. Affected files lib/silcutil/silcbuffer.h,
3837 lib/trq/silcdlist.h and lib/trq/silclist.h.
3839 * Print warning in log files from now on if the packet
3840 decryption fails. Affected file silcd/server.c.
3842 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3844 * Changed the `say' client operation's interface to accept
3845 new `type' argument to indicate the type of the message sent
3846 by the library. The application may filter the library's
3847 messages according the type. The affected file is the
3848 lib/silcclient/silcapi.h.
3850 * Added two new functions to lib/silcclient/silcapi.h:
3851 silc_client_del_client and silc_client_del_client_by_id.
3852 Affected file lib/silcclient/idlist.c.
3854 * Moved the clientincludes.h from includes/ to silc/ and
3855 serverincludes.h from includes/ to silcd/.
3857 * The modes for the CMODE and CUMODE are now passed as
3858 uint32 for application with COMMAND_REPLY. The affected
3859 file is lib/silcclient/command_reply.c.
3861 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * /WHOIS without arguments shows client's own information.
3864 Affected file lib/silcclient/command.c.
3866 * Changed PING to not accept any arguments. The specs
3867 says that client can ping only the connected server so
3868 requiring an argument is not needed. Affected file is
3869 lib/silcclient/command.c.
3871 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3873 * Fixed a fatal bug in private message sending and reception
3874 encryption and decryption when using private message keys.
3875 The implementation was incorrect and did not follow the
3876 specification. It causd that some of the message were
3877 lost since it did not use the sending and receiving keys
3878 as the protocol suggests. This has been fixed and will cause
3879 incompatibilities with older clients when sending private
3880 message encrypted with private message keys. Affected files
3881 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3882 and various other in Irssi SILC Client.
3884 Added `responder' boolean argument to the functions
3885 silc_client_add_private_message_key[_ske] to indicate when
3886 the key is added as responder or initiator of the key
3889 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3891 * Removed the silc_ske_check_version function and created
3892 a SilcSKECheckVersion callback. Added also a function
3893 silc_ske_set_callbacks that is now used to set all SKE
3894 callbacks. The callback functions are not given to
3895 the SKE functions anymore, but this function is used to
3898 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3900 * Added `silc_version' argument to the silc_client_alloc
3901 to define the version of the application for the library.
3902 The library will use the version string to compare it
3903 against the remote host's (usually a server) version
3904 string. Affected file lib/silcclient/silcapi.h
3906 * Added the KE protocol context to Key Agreement context
3907 in client library so that we can abort the SKE if it
3908 is in process when we get timeout. Affected file is
3909 lib/silcclient/client_keyagr.c.
3911 * Do not resolve the client ID forever if it returns in the
3912 first time that such client does not exist. This was done
3913 for example with private message. Affected file is
3914 lib/silcclient/client_prvmsg.c.
3916 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3918 * Do not add regex.h for WIN32. The affected file
3919 includes/silcincludes.h.
3921 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3922 not work yet 100%. It generates the DLL's automatically
3923 when compiling with --with-win32 under cygwin.
3925 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * lib/contrib/regex.c is not compiled on WIN32.
3929 * Added silc_net_get_socket_opt function to the
3930 lib/silcutil/silcnet.h.
3932 * Added includes/silcwin32.h for WIN32 specific includes
3935 * Do not use ptime structure or any of the posix process
3936 functions on WIN32 in lib/silccrypt/silrng.c.
3938 * Added silc_gettimeofday to provide generic function
3939 for struct timeval on all platforms. Added the function
3940 to lib/silcutil/silcutil.h.
3942 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3944 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3945 library as they clearly belong there. As a plus side we
3946 can make the actual socket connection routines platform
3949 Added also new generic function silc_socket_read and
3950 silc_socket_write (that used to be silc_packet_[read/write].
3951 The implementation of these are platform specific.
3953 * Added WIN32 specific routines of silc_socket_[read/write]
3954 to lib/silcutil/win32/silcwin32sockconn.c.
3956 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3958 * Added preliminary support for native WIN32 compilation under
3959 cygwin (using the -mno-cygwin option for GCC) to the
3960 ./configure.in.pre. The --with-win32 now prepares the
3961 compilation for native WIN32.
3963 * Rewrote the SILC Scheduler interface in the file
3964 lib/silcutil/silcschedule.h. The scheduler is now context
3965 based and does not have anymore any global static scheduler.
3966 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3967 and created lib/silcutil/win32 directory for WIN32 based
3970 * Added Unix specific network routines to the
3971 lib/silcutil/unix/silcunixnet.c and the old
3972 lib/silcutil/silcnet.c includes now only generic routines.
3974 Added WIN32 specific network routines to the
3975 lib/silcutil/win32/silcwin32net.c.
3977 * Added Unix specific utility functions from the
3978 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3980 * Added WIN32 SILC Scheduler to the file
3981 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3984 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Do not handle JOIN notify in the server if the target client
3987 is not registered (idata->registered == FALSE). The affected
3988 file is silcd/packet_receive.c.
3990 * Update the nickrec->founder in event_cumode in the Irssi SILC
3991 client. Affected file irssi/src/silc/core/silc-channels.c.
3993 * Fixed the CUMODE_CHANGE notify handling in the server when
3994 server and router are announcing their clients on channels.
3995 Now the mode changes are saved and notified correctly. The
3996 affected file is /silcd/packet_receive.c.
3998 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3999 They really did not replace the cache entry in the ID Cache.
4000 Now they do that. Affected file silcd/idlist.c.
4002 * Fixed the KICK notify handling in the Irssi SILC client to
4003 update the channel records so that the kicked client does not
4004 appear to be on the channel. The affected file is
4005 irssi/src/silc/core/silc-channels.c.
4007 * Always update the conn->current_channel when executing command
4008 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4010 * Fixed the KILL notify handling in Irssi SILC client to remove
4011 the killed client on all channels.
4013 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Fixed the silc_parse_command_line to remove extra spaces
4016 from the start and end of the arguments. Affected file is
4017 lib/silcutil/silcutil.c.
4019 * Cancel and free any active protocol in the function
4020 silc_server_close_connection. Affected file silcd/server.c.
4022 * Cancel and free any active protocol in the function
4023 silc_client_close_connction. Affected file is
4024 lib/silcclient/client.c.
4026 * Do not execute the KILL command for clients that are in
4027 history (ie. they are not in the network). Affected file is
4030 * Fixed KILL notify handling, client does not crash anymore.
4031 Affected file irssi/src/silc/core/silc-channels.c.
4033 * Reduced the default packet buffer size from 2048 to 1024 in
4034 lib/silccore/silcpacket.c.
4036 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4037 counter to the SKE context that is incresed when the SKE library
4038 performs async operation outside the library. If the outside
4039 process frees the SKE context and FREED status will be set
4040 and the library will detect after the sync operation that the
4041 libary is freed. The affected files are
4042 lib/silcske/silcske[_status].[ch].
4044 * Resolve the client entry information in the function
4045 silc_client_channel_message to assure that NULL pointer is not
4046 passed as client entry to the application. */
4048 * Fixed the task timeout calculation to assure that there is
4049 never negative timeouts. The affected file is
4050 lib/silcutil/silcschedule.c.
4052 * Fixed the channel user mode notification sending in server.
4053 It was sent point-to-point to the router (or to server by router)
4054 but it needs to be destined to a channel. The routines now
4055 supports sending the channel user mode notifys to the channels
4056 when announcing clients and channels. Affected files are
4057 silcd/server.c and silcd/packet_receive.c.
4059 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4060 It did not actually replace the old channel entry in the cache.
4061 Affected file lib/silcclient/client_notify.c.
4063 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Fixed a possible crash in silc_packet_send_prepare. It now
4066 assures always that there is enough space in the buffer and
4067 at the tail area of the buffer (for MAC).
4069 Fixed the inbound buffer reallocation in silc_packet_read.
4070 It was old code and did not handle the reallocation correctly.
4073 The affected file is lib/silccore/silcpacket.c.
4075 * Fixed buffer overflow in silc_parse_nickname in the file
4076 lib/silcutil/silcutil.c.
4078 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * make install generates new server keys only if there is not
4083 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4086 Added check that if the NOREPLY is set then we will not send
4087 the away message. This avoids infinite loop of away messages
4088 if both clients are away. The affected file is
4089 lib/silcclient/client_prvmsg.c.
4091 * Fixed client crash if /NICK was given without arguments.
4092 Affected file lib/silcclient/command.c.
4094 * Server does not send the invite list in INVITE command back
4095 to the client if the list was not altered. Added this notion
4096 to the protocol spec as well. Affected file silcd/command.c.
4098 Fixed possible crash in INVITE command by checking the
4099 value of silc_server_get_client_route command.
4101 * Fixed the INVITE notify type handling. The arguments are now
4102 taken in correct order and client does not crash. The affected
4103 file is irssi/src/silc/core/silc-channels.c.
4105 Removed the "Inviting xxx to channel" message from the
4106 client library away and let the application handle it.
4107 Affected file lib/silcclient/command.c. Added that message
4108 to Irssi SILC client's message formats.
4110 * Fixed CMODE command crash in client. It now checks the
4111 amount of arguments correctly and does not crash. The affected
4112 file is lib/silcclient/command.c.
4114 * Do not create new channel automatically in silc_channels_join
4115 but check whether the channel by that name already exists.
4116 Affected file irssi/silc/core/silc-channels.c.
4118 * Do not send the SERVER_SIGNOFF to router if the disconnected
4119 entity was the router. Affected file silcd/server.c.
4121 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4122 SILC client as it was missing from there.
4124 Added the handling of the KICK notify to the Irssi SILC client
4125 as it was missing. Added "you have been kicked" message to
4126 Irssi SILC client's message modules formats.
4128 Added the handing of the KILL notify to the Irssi SILC client
4129 as it was missing. Added the kill message module formats
4132 The affected file is irssi/src/silc/core/silc-channels.c.
4134 * The router did not save the channel mode the server announced.
4135 Affected file silcd/packet_receive.c.
4137 * Fixed a possible crash in INFO command in server. If the
4138 server did not provide the server info it crashed. Affected
4139 file silcd/command.c.
4141 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Fixed the GETKEY command in the server to check also the
4144 global list. Otherwise the GETKEY would not work correctly
4145 in normal SILC server. Affected file silcd/command.c.
4147 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Fixed GETKEY crash, it crashed if the command did not succseed.
4151 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4154 is now real and not just an macro interface to GMP.
4156 Removed the entire GMP from the source tree and imported new
4157 NSS MPI library instead. Reason for removing GMP is that it is
4158 extremely large and compiles extremely slow. The NSS MPI
4159 is only a few files and compiles in less than 10 seconds.
4160 The speed is also about the same as GMP. The MPI is imported
4161 to lib/silcmath/mpi.
4163 If the system has GMP installed we will still use the GMP.
4164 If it is not then the NSS MPI will be compiled.
4166 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Merged a long nickname (127 characters long) crash bugfix from
4169 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4171 * Merged a freed memory reference bugfix from Irssi CVS tree.
4172 Affected file irssi/src/core/commands.c.
4174 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added the server's public key sving and verification to the
4177 server when performing the SKE. This was missing and the
4178 remote server's (or router's) public key was accepted without
4179 checking whether we have it previously or trust it at all.
4180 Affected file silcd/protocol.c.
4182 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Check in the silc_server_timeout_remote if protocol is active
4185 and make sure that the protocol's final callback is called so
4186 that all memory if freed. Affected file silcd/server.c.
4188 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * silc_server_whois_send_reply crashed the server if the nickname
4191 was 127 characters long. Affected file silcd/command.c.
4193 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Added sanity check to the silc_server_new_client. If the hostname
4196 is provided inside username then check that the provided hostname
4197 really is the same as the resolved one. If the hostname was not
4198 resolved then check it from the public key. Affected file is
4199 silcd/packet_receive.c.
4201 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4202 if the server disconnected us and the connection is not valid
4203 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4205 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4206 the library to the lib/silcutil/silcutil.[ch].
4208 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Close log file after open. Affected file
4211 lib/silcutil/silclog.c.
4213 * Check whether sock == NULL in silc_client_send_packet and return
4214 if it is. Affected file lib/silcclient/silcclient.c.
4216 * Check rec->entry == NULL in the Irssi SILC Client before
4217 sending the channel message. Affecte file is
4218 irssi/src/silc/core/silc-servers.c.
4220 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Merged a splitted window bugfix from Irssi CVS tree. The
4223 affected file is irssi/src/fe-text/textbuffer-view.c.
4225 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4226 It did not print nickname.
4228 * Improved the distributions system a bit.
4230 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4233 irssi/src/fe-text/gui-window.c.
4235 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4236 to in-active server. The affected file is
4237 irssi/src/silc/core/client_ops.c.
4239 * Resolve the client in USERS command reply if the entry does
4240 not have username resolved. The affected file is
4241 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4242 command to WHOIS command to really resolve stuff. The USERS
4243 is not used any more in any critical section so WHOIS can
4244 be used even though it might be slower than IDENTIFY.
4246 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4249 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Changed the protocol API a bit more consistent in the
4252 lib/silccore/silcprotocol.[ch].
4254 * Changed the following headers to ROBODoc format:
4256 lib/silccore/silcpayload.h
4257 lib/silccore/silcprotocol.h
4258 lib/silccore/silcsockconn.h
4260 All core library headers are now formatted.
4262 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Fixed a bug in Irssi SILC client; do not show that you are
4265 server/router operator if you really are not. Affected file is
4266 irssi/src/silc/core/client_ops.c.
4268 * Renamed silc_command_free_payload to silc_command_payload_free.
4269 Affected file lib/silccore/silccommand.h
4271 * Added silcmath.h to include the prototoypes of various routines
4272 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4275 * Changed the following headers to ROBODoc format:
4277 lib/silccore/silcchannel.h
4278 lib/silccore/silccommand.h
4279 lib/silccore/silcid.h
4280 lib/silccore/silcidcache.h
4281 lib/silccore/silcmode.h
4282 lib/silccore/silcnotify.h
4283 lib/silccore/silcpacket.h
4284 lib/silcmath/silcmath.h
4286 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * Added checking to the server code not to start the server if
4289 ciphers and stuff are not configured properly. Affected files
4290 silcd/serverconfig.[h] and silcd/server.c.
4292 * Changed the layout of the header files of the public interfaces
4293 in the SILC libraries. The new layout supports ROBODoc
4294 documentation tool (and some others) so that it is easy to create
4295 a library reference manual. All the other headers and source
4296 code must still follow the CodingStyle document. Also source
4297 code must not include these ROBODoc stuffs, only the headers.
4298 Furthermore, all public interface headers must now be named
4299 by using `silc' prefix, example: silcapi.h, silccipher.h.
4300 Some files were renamed due to this. All the other headers
4301 must not be used as public interfaces. I will update the
4302 CodingStyle document later. Changed following headers, so far:
4304 lib/silcclient/silcapi.h
4305 lib/silccore/silcauth.h
4306 lib/silccore/silcprivate.h
4307 lib/silccrypt/silcdh.h
4309 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Removed silc_client_packet_send_flush from the client library
4314 as it is not needed. Affected file lib/silcclient/client.[ch].
4316 * Added printing of message of unresolved authentication method
4317 to the Irssi SILC client. Added it to the module formats.
4318 Removed the same message from the client library.
4320 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Added new distribution feature, DISTLABEL. Every distribution
4323 can define own preprocessor label that can be used in the
4324 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4325 file distributions, acconfig.h.pre and prepare.
4327 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Added Makefile.defines_int to include the actual definitions
4330 for Makefile.defines.in. Tested the new distribution system,
4331 created distributions and tested installation.
4333 * Added AWAY message printing to the Irssi SILC client. Added
4334 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4336 * Added SCONNECT command to call the SILC's CONNECT command.
4337 Cannot use CONNECT directly since Irssi uses that internally.
4338 Affected file irssi/src/silc/core/silc-servers.c.
4340 Added ACTION local command. It is same as ME command but takes
4341 the channel as mandatory argument.
4343 Rewrote some of the Irssi's help files to suite for SILC
4346 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Added Makefile.defines[.in] that should for now on be included
4349 in all Makefile.am file in the source tree. That file includes
4350 all common compilation definitions for SILC source tree.
4352 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Minor changes to the ./prepare script to change the package
4355 name according the distribution name to the configure.in.
4357 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Created new distribution system. Added file `distributions'
4360 that defines all the distributions that can be created out of
4361 the SILC source tree. The ./prepare script now reads that
4362 file to determine how to prepare the distributions. The
4363 first argument to the ./prepare is the name of the distribution
4364 and second is the version of the distribution. If given
4365 without arguments it creates the default (toolkit) distribution
4366 with the default version (defined in ./prepare).
4368 All Makefile.am files that are subject to the distributions
4369 are now named as Makefile.am.pre. These are ./Makefile.am
4370 and lib/Makefile.am. Others may be changed later.
4372 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Added invite list, ban list, some key management and connection
4375 error message printing to module formats in the Irssi SILC client.
4377 * Added new silc_client_set_away_message to set the away message
4378 that is back to the person who sent private message. The
4379 affected file lib/silcclient/silcapi.h and the
4380 lib/silcclient/client_prvmsg.c.
4382 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Fixed the private message sending in the Irssi SILC client,
4385 added local command KEY to the Irssi SILC client.
4387 Added key management and key agreement message formats to the
4388 irssi/src/fe-common/silc/module-formats.[ch].
4390 Added USERS (alias WHO) printing, server/router operator
4391 indication and LIST command printing to the module formats.
4393 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed channel joining notify handling, cumode notify handling
4396 from Irssi SILC client.
4398 * Added SILC specific module-formats to the Irssi SILC client so
4399 that SILC specific message hilighting, colors etc is possible.
4400 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4402 Added channel mode, channel user mode, actions, notices,
4403 whois and whowas printing to the the module-formats.c.
4405 * Fixed a bug in channel deletion in the server. The channel
4406 is not left to the cache even if the channel founder auth mode
4407 is set when there are no users anymore on the channel. Affected
4408 file silcd/server.c.
4410 * The silc_net_localhost now resolves the entire hostname including
4411 the domain name. Affected file lib/silcutil/silcnet.c.
4413 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Changed the ask_passphrase client operation to be ascynchronous.
4416 It has now a completion callback and a context that the
4417 application must call after it has got the passphrase from
4418 the user. Affected files lib/silcclient/silcapi.h,
4419 lib/silcclient/protocol.c, lib/silcclient/command.c and
4422 Added SilcAskPassphrase callback that the application calls
4423 to deliver the passphrase to the library.
4425 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4426 The public key verification and especially a certificate
4427 verification is asynchronous procedure.
4429 Added new SILC_SKE_STATUS_PENDING status to indicate the
4430 request is pending and a callback will be called to finalize
4433 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4434 indicate that remote end did not send its public key (or
4435 certificate), even though we require it. Added check for this
4436 condition in the SKE. This was a security bug, now fixed.
4438 Defined new SilcSKEVerifyCbCompletion callback that is called
4439 when the verification process is completed.
4441 The affected files lib/silcske/silcske_status.h and
4442 lib/silcske/silcske.[ch].
4444 * Changed the verify_public_key client operation to be async
4445 as well. Defined SilcVerifyPublicKey callback that is used to
4446 indicate the success of the public key verification process.
4448 Changed the server and client to use the new async client
4451 * Changed the Irssi SILC client's internal scheduler to be called
4452 twice as many times as it used to be. As a result the client
4453 should be a bit faster now. Affected file is
4454 irssi/src/silc/core/silc-core.c.
4456 * Added support to Irssi SILC client of asynchronous public key
4457 verification and passphrase inquiry. Affected file is
4458 irssi/src/silc/core/silc-core.c.
4460 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Do not say "You have left channel %s" in client library.
4463 Moved it to the application. Affected files are
4464 lib/silcclient/command.c and silc/client_ops.c.
4466 * Fixed silc_client_get_clients. Command context was not
4467 duplicated and was freed memory in the callback. Affected
4468 file lib/silcclient/idlist.c.
4470 * Do not say "you are now talking..." on JOIN command in the
4471 client library. The appliation must handle it.
4473 * Do not say ".. changed topic to" in command reply in the
4474 client libary. The application must handle it.
4476 * Fixed TOPIC command sending in the client library.
4478 * Fixed a memory leak in silc_client_command_free in the file
4479 lib/silcclient/command.c.
4481 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Imported a modified version of Irssi client to the source tree.
4484 The Irssi will be used to create a new client called
4485 Irssi SILC. Imported to irssi/.
4487 Added silc_core_init_finish function to the Irssi. Affected
4488 file irssi/configure.in.
4490 A lot changes in the Makefile.ams around the irssi tree.
4492 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Do not rehash if the new size is same as the old size of the
4495 hash table, in the silc_hash_table_rehash*. The affected file
4496 lib/silcutil/silchashtable.c.
4498 * Replaced hash_table_del_by_context calls from the server
4499 (when channel->user_list and client->channels) to the
4500 hash_table_del as it is sufficient and faster.
4502 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added silc_hash_table_list, silc_hash_table_get and the
4505 SilcHashTableList structure to provide an alternative way to
4506 traverse the hash table. The affected files are
4507 lib/silcutil/silchashtable.[ch].
4509 * Changed the server's idlist routines to use the hash table
4510 routines to optimize the code.
4512 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Replaced the client entry's `channel' list and channel entry's
4515 `user_list' list to hash tables for optimized lookup. Changed
4516 the code to use the hash table interface around the code.
4517 Affected file lib/silcd/idlist.[ch].
4519 * Added `auto_rehash' boolean argument to the function
4520 silc_hash_table_alloc to indicate whether the hash table should
4521 auto-rehash when it thinks is appropriate time. It will
4522 increase the hash table size if the there is twice as much
4523 entries in the table than the size of the table, and will
4524 decrease the size if there are twice as less entries than
4525 the size of the table.
4527 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4531 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * silc_idcache_purge_by_context deletes the entry now by context
4534 as it is supposed to do. Affected file lib/silccore/idcache.c.
4536 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4537 client is not anymore valid (WHOWAS givens the info) and not
4538 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4540 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Removed the `data' and `data_len' arguments from the ID Cache
4543 interfaces and added `name' argument. ID Cache does not handle
4544 anymore the binary data only a names associated with given ID.
4546 * When hashing a Client ID with silc_hash_id the entire ID is
4547 not hashed anymore, instead only the hash of the Client ID is
4548 hashed. This way we can access the Client ID from the cache
4549 with Client ID but with the hash of the ID (which is a hash of
4550 the nickname) as well without any difference in performance.
4552 Added also silc_idcache_find_by_id_one_ext to do one on one
4553 searching when we have the actual ID. Added also function
4554 silc_hash_client_id_compare. The affected files are
4555 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4557 * When hashing the name associated with a ID it is always done
4558 in lowercase. This way we can access the cache without worrying
4559 about case-sensitivity, even though, for example nicknames are
4562 * Fixed a bug in server with channel message sending. It put
4563 wrong ID type as destination ID. The affected file
4564 silcd/packet_send.c.
4566 * silc_idcache_del_by_context now deletes from all hash tables
4567 by context. Affected file lib/silccore/idcache.c.
4569 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Changed the client library to use the new ID Cache interface.
4572 Changes around the source tree.
4574 * Added silc_hash_table_rehash_ext to rehash with specific
4575 hash function. Affected file lib/silcutil/silchashtable.[ch].
4577 * Added silc_hash_string_compare to compare two strings in the
4578 hash table. Affected file lib/silcutil/silcutil.[ch].
4580 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Added new function silc_idcache_del_by_context into the
4583 lib/silccore/idcache.[ch].
4585 * Changed the server's ID list routines to use the new ID Cache
4586 interface. Changes around the source tree.
4588 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added silc_hash_table_del[_by_context]_ext functions in to the
4591 lib/silcutil/silchashtable.[ch].
4593 Removed silc_hash_table_find_all* routines and added new
4594 silc_hash_table_find_foreach to replace them.
4596 Added silc_hash_table_replace_ext function as extended
4597 replacing function. Separated the simple hash table interface
4598 from the extended hash table interface in the file
4599 lib/silcutil/silchashtable.h.
4601 * Fixed minor bugs and changed it to use some of the new
4602 hash table functions in lib/silccore/idcache.c
4604 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Added new function silc_hash_table_find_all to return all keys
4607 in the hash table by the specified key. As the hash table is
4608 collision resistant it also makes it possible to have several
4609 duplicate keys in the hash table. This function may be used to
4610 find all of the keys from the hash.
4612 Added user_context arguments to the SilcHashFunction,
4613 SilcHashCompare and SilcHashDestructor to deliver user specified
4616 Added new fuctions silc_hash_table_find[_all]_ext to do
4617 extended lookup with specified hash and compare functions and
4618 specified user contexts.
4620 Added new function silc_hash_table_add_ext to add the key
4621 with specified hash function and user context.
4623 Added new function silc_hash_table_foreach to traverse all
4624 entrys in the hash table. Added SilcHashForeach callback
4627 Added new function silc_hash_table_del_by_context to delete
4628 the entry only if the context associated with the key matches.
4630 Affected files are lib/silcutil/silchashtable.[ch].
4632 * Removed silc_hash_[server/client/channel]_id and added just
4633 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4634 silc_hash_id_compare to compare two ID's using as the hash table
4635 comparison function. Added also silc_hash_data to hash
4636 binary data and silc_hash_data_compare to compare it.
4638 * Removed silc_idlist_find_client_by_hash as it is not needed
4639 anymore. Affected file silcd/idlist.[ch].
4641 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4642 to use internally the SilcHashTable. The new ID Cache is a lot
4643 faster than the old one. Some of the ID Cache interface was also
4644 rewritten and obsolete and stupid functions were removed.
4646 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Added entry_count field to the SilcHashTable to keep the number
4649 of the entries in the table. Implemented the function
4650 silc_hash_table_rehash. Added new function
4651 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4653 Fixed a minor bug in silc_hash_table_free.
4655 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4656 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4657 into the lib/silcutil/silcutil.[ch].
4659 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Implemented a collision resistant hash table into the
4662 lib/silcutil/silchashtable[ch]. See the header and the source
4663 for the SilcHashTable API.
4665 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Merged dotconf version 1.0.2 into lib/dotconf.
4669 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Do not compile anything in lib/silcsim/* if the SIM support
4672 is not enabled. The tree should now compile without problems
4675 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Compiled the SILC under cygwin. Compiled and tested briefly
4678 without problems. More tests needed. The SIMs didn't compile
4681 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4683 * Fixed possible crash in silc_get_username in the
4684 lib/silcutil/silcutil.c.
4686 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Fixed a va_arg in silc/client_ops.c.
4690 * Oops, RC5 routines were named AES and caused some problems
4691 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4693 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Added new SilcIDIP structure into the lib/silccore/id.h and
4696 replaced the old `ip' fields from all SILC ID's to that type.
4697 This is a step towards IPv6 support.
4699 The silc_id_get_len takes now the ID as an extra argument.
4700 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4701 both IPv4 and IPv6 based ID's.
4703 The affected files are lib/silccore/id.[ch] and other files
4704 around the tree using these routines.
4706 * Removed the ID length arguments in server from various
4707 silc_server_send_notify_* routines -> they are not needed
4710 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Fixed memory leak in silc_encode_pem_file in the file
4713 lib/silcutil/silcutil.c.
4715 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Check minor version as well in the SKE. Affected files are
4718 silcd/protocol.c and lib/silcclient/protocol.c.
4720 * Added --identifier option to the server so that an identifier
4721 can be when creating the public key for the server. Affected
4722 file is silcd/silcd.c.
4724 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4725 lib/silccrypt/silcpkcs.c.
4727 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Register default ciphers and stuff when using -C option with
4730 the server. Affected file sildc/silcd.c.
4732 * Put back the servers public key filename format, it is better
4733 than the new one. For now, the client keys are saved with the
4734 new filename format. The affected file silc/client_ops.c.
4736 * Implemented the Cipher API for the rest of the ciphers that
4737 did not implement it or implemented it the wrong way.
4739 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Register default ciphers and stuff when using the -S option
4742 in the client. Affected file silc/silc.c. Same also when
4743 creating new key pair with -C option.
4745 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Fixed the silc_verify_public_key client operation function to
4748 save the public keys differently. The fingerprint is now
4749 used as filename and not the hostname. This way also the
4750 client keys are saved uniquely and not with hostnames. The
4751 affected file is silc/client_ops.c.
4753 * Trimmed the silc_hash_fingerprint function to remove extra
4754 whitespaces from the end of the fingerprint. The affected
4755 file is lib/silccrypt/silchash.c.
4759 * Added silc_cipher_register_default function to register all
4760 default ciphers. It can be used when configuration files
4761 does not exist and the application does not want any specific
4762 ciphers in any specific order.
4764 The SilcDList is now used as silc_cipher_list dynamically
4765 allocated cipher list. Removed the static list all together
4766 and now all ciphers must be allocated to the dynamic list.
4767 The silc_cipher_alloc routine was changed to check only the
4770 All silc_cipher_* routines that used to return int returns
4773 The affected files lib/silccrypt/silccrypt.[ch].
4775 * The same thing was done to silc_hash_* as for silc_cipher_*
4776 routines. Affected files lib/silccrypt/silchash.[ch].
4778 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4779 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4780 Added also silc_pkcs_[un]register[_default] functions.
4781 Removed the data_context from the PKCS API.
4783 * Added silc_hmac_register_default function to register default
4784 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4785 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4786 to unregister all hmacs at once.
4788 * Register the default ciphers, hash functions, PKCSs and HMACs
4789 if client's configuration file does not exist. The affected
4792 * The client did not load the hash functions from the SIM
4793 modules at all. Added support for this. Affected file is
4794 silc/clientconfig.c.
4796 * When decoding public key with silc_pkcs_public_key_decode, check
4797 the supported algorithm only if PKCS are registered. Affected
4798 file lib/silccrypt/silcpkcs.c. The same was done with the
4799 silc_pkcs_private_key_decode.
4801 * Fixed the SILC List routines to keep the list always in order.
4802 It used to change the list's order when traversing the list but
4803 not it preserves the order. Affected file lib/trq/silclist.h.
4805 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added the client library to use the SilcSocketConnection's
4808 reference counter (by silc_socket_dup) to prevent the bug that
4809 the socket object may be freed underneath async operation.
4811 * The name resolv library checking fixes in the configure.in.pre.
4814 * Created new version of the protocol drafts for future
4815 development. The -03 drafts are the ones that will be changed
4816 in the trunk now and the -02 will remain as they are.
4818 * Send list of CUMODE notifys to the router when announcing
4819 the channel users to the router. Affected file silcd/server.c.
4820 If the router receiving channel founder CUMODE for a channel
4821 that already has channel founder it will send CUMODE notify
4822 to the sender to remove the channel founder rights from the
4823 announced client. Affected file silcd/packet_receive.c.
4825 * The CUMODE notify may now use Server ID as well as the entity
4826 who changes the mode. Updated protocool specs.
4828 * Updated INSTALL and README files.
4830 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * New web pages in the http://silc.pspt.fi. The pages was
4837 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Implemented the [DenyConnectin] config section in the server.
4840 Added silc_server_config_denied_conn to check whether incoming
4841 connection is denied. Affected file silcd/serverconfig.[ch].
4843 * Do not check the ports when checking the incoming configuration
4844 data if the port is 0, meaning any. Affected file is
4845 silcd/serverconfig.c.
4847 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Fixed buffer overflow in silc_string_compare in the file
4850 lib/silcutil/silcutil.c.
4852 * Fixed double free in silc_server_command_leave in the file
4855 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Fixed the version checking in the server. Affected file is
4860 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Fixed the configuration data fetching when accepting new
4863 connections in the server. Affected file silcd/server.c.
4865 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Added `sender_entry' argument to the function
4868 silc_server_packet_relay_to_channel so that we can check
4869 whether some destination actually belongs to the same route
4870 the sender belongs (ie, we must not resend the packet to the
4871 sender). Affected file silcd/packet_send.[ch].
4873 * Added `servername' field to the SilcClientEntry in the server
4874 to hold the name of the server where client is from. Affected
4875 file is silcd/idlist.h.
4877 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Moved the channel message encrypting in the router betwen
4880 router connections from silc_server_channel_message to the
4881 silc_server_packet_relay_to_channel since we want to check
4882 whether we have anybody channel before encrypting anything.
4883 Affected files silcd/packet_[receive/send].c.
4885 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Fixed the [AdminConnection] server config section to support
4888 multiple entries. Affected file silcd/serverconfig.c.
4890 * Added support into the server to check the validity of the
4891 incoming connection before executing any KE or authentication
4894 * The connection configuration is now saved to the KE and
4895 connection auth protocol contexts and not fetched anymore in
4896 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4898 * The local hosts listenning address and port is also resolved
4899 now when starting the server. We want to have the socket object
4900 to include the real address and port for the listener. Added
4901 new function silc_net_check_local_by_sock into the files
4902 lib/silcutil/silcnet.[ch].
4904 * Fixed a broadcast bug in server -> do not broadcast if we
4907 * Fixed a routing bug. Do not route broadcast packets ever.
4908 Broadcast packets must be processed always and not routed since
4909 they may be destined to some other host than yourself and thus
4910 would get routed without no good reason. Affected file is
4913 * Added function silc_server_config_is_primary_route to check
4914 whether primary router connection has been configured (a router
4915 configuration that we are initiating). If there is not, we
4916 will assume that there is only two routers in the SILC network
4917 and we will use the incoming router connection as our primary
4918 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4920 * Changed the order of the broadcasting. Broadcast _after_ the
4921 packet has been processed not before. Affected file is
4924 * Fixed a [ClientConnection] parsing bug. The port was never
4925 parsed correctly thus resulting to port 0. Affected file
4926 silcd/serverconfig.c.
4928 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4929 argument and did not set the broadcast packet flag. Affected
4930 file silcd/packet_send.c. Fixed same bug in the function
4931 silc_server_send_notify as well.
4933 * If we receive NEW_ID packet for our own ID in the server, ignore
4936 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Removed the nickname from the Private Message Payload.
4941 Updated the code and the protocol specs.
4943 * Updated protocol specs for submitting to the IETF.
4945 * Tweaked the Random Number Generator a bit. Affected file
4946 lib/silccrypt/silcrng.c. Exported a new function
4947 silc_rng_[global]_add_noise which can be used to add more
4950 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Do not parse packets with different timeout when protocol
4953 is active -> may cause problem with rekey. Affected file
4956 * When server receives signoff notify it must not create
4957 new channel key if the client is on any channels since the
4958 sender of the signoff notify will create it.
4960 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Added printing of error messages during SKE protocol from the
4963 failure packet sent by server during SKE. Affected file
4966 * Removed the client's failure_callback handling with timeout
4967 and handle it immediately when received.
4969 * The SKE library returned wrong type in SUCCESS and FAILURE
4970 packets. They must be 32 bit MSB not 16 bit MSB.
4972 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Ok, rewrote the logic of the re-key and now it seems to work.
4975 I tested it on high traffic with frequent re-keys without
4976 problems. Added hmac_receive (and renamed hmac to hmac_send)
4977 in SilcClientConnection in lib/silcclient/client.h and
4978 in SilcIDListData in silcd/idlist.h. Also, removed the
4979 SilcPacketParserContext's cipher and hmac fields as they are
4980 not needed anymore and actually caused some problems when
4981 the ciphers and hmac's changed underneath the packet parser.
4983 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * If re-key protocol is active then process the incoming packets
4986 synchronously since we must assure that icoming packets encrypted
4987 with the old key is processed before the new keys is set to
4988 use. This is true other packets than for REKEY packets.
4989 Affected file silcd/server.c. The same was done to client library
4990 as well, affected file lib/silcclient/client.c.
4992 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Fixed bug in client and server to accept the force send if
4995 the packet is send from silc_[server/client]_packet_process
4996 function. Otherwise the packets are never delivered, oops.
4998 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Disable force sending of packets when REKEY protocol is active.
5001 We must assure that no packet is sent directly when rekey is
5002 performed. All packets must be sent through packet queue.
5003 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5004 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5005 function is silc_[server/client]_packet_send_real to check
5008 * Replaced the SIM paths from example config files to
5009 /usr/local/modules. Also, make install creates now
5010 /usr/local/silc/logs directory to hold all the SILC server
5013 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Made the configure.in.pre work on Solaris. Patch by salo.
5017 * Made all ciphers compatible with non-x86 machines. Defined
5018 CBC mode macros into lib/silccrypt/ciphers_def.h.
5020 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Fixed the make install.
5024 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * When MAC computation fails the silc_packet_decrypt returned 0
5027 even though it was supposed to return -1. Fixed this. The
5028 affected file is lib/silccore/silcpacket.c.
5030 * Do not replace the config files in /etc/silc (in make install)
5031 if they already exist. Affected file ./Makefile.am.
5033 * Do not send re-key packets immediately but through packet queue.
5034 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5036 * Changed silc_net_check_host_by_sock to return FALSE if the
5037 IP/DNS could not be resolved. Though, it returns the IP address
5038 now even if it could not resolve it (but returns also FALSE).
5039 Affected file lib/silcutil/silcnet.[ch].
5041 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Added silc_pkcs_decode_identifier to decode the public key's
5044 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5045 Added also silc_pkcs_free_identifier. Added also new context
5046 SilcPublicKeyIdentifier.
5048 * Added -S option to the silc client. It is used to dump the
5049 contents of the specified public key file.
5051 * Changed the PKCS api to return the public key length when
5052 setting the public key.
5054 * Fixed a fatal bug in the public and private key file loading.
5055 Affected file lib/silccrypt/silcpkcs.c.
5057 * Execute the packet parsing for client with zero (0) timeout
5058 if the protocol is active. Affected file silcd/server.c.
5060 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Made the key generation options to the silcd program. Added
5063 -C option, equivalent to client's option.
5065 * Added new [ServerKeys] config section to the server. It
5066 configures the server's public and private key.
5068 * Defined generic Public Key Payload into the protocol
5069 specification to send specific type of public keys and
5072 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5073 public key or certificate.
5075 * Implemented the GETKEY command to the server and to the
5076 client library and on user interface.
5078 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Made preliminary `make install' work.
5082 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Added SilcServerRekey context into silcd/idlist.h.
5086 * Added the PFS support as defined in the specification to the
5087 SKE protocol. Affected files lib/silcske/*.c.
5089 * Added `ske_group' field to the SilcServerRekey context to hold
5090 the number of the SKE group that is used with PFS in re-key.
5091 Affected file silcd/idlist.h.
5093 * Added PFS re-key support to the server. Affected file is
5096 * Added silc_protocol_cancel to cancel execution of the next
5097 state of the protocol. Affected file is
5098 lib/silccore/silcprotocol.[ch].
5100 * Added the re-key support with and without PFS to the client
5101 library. Re-key is performed once in an hour, by default.
5103 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5104 Added silc_client_rekey_callback and silc_client_rekey_final.
5105 Affected files are lib/silcclient/protocol.[ch] and
5106 lib/silcclient/client.[ch].
5108 * Removed the `hmac_key' and `hmac_key_len' fields from the
5109 SilcClientConnection structure; not needed. Affected file is
5110 lib/silcclient/client.h.
5114 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5116 * Do not ask whether user wants to use the negotiated private key
5117 for private messages, just use it. Affected file is
5118 silc/local_command.c.
5120 * Added `send_enc_key' and `enc_key_len' fields to the
5121 SilcIDListData structure since they are needed in the re-key
5122 phase. Affected file is silcd/idlist.[ch].
5124 * Implemented the simple re-key protocol into the server.
5125 Affected files silcd/server.c and silcd/protocol.[ch]. The
5126 re-key will be performed once in an hour, by default.
5128 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5129 Added silc_server_rekey, silc_server_rekey_callback and
5130 silc_server_rekey_final.
5132 * Removed Tunneled flag from the protocol. Updated the code
5133 and the specifications.
5135 * Adde `pfs' field to the SilcIDListData to indicate whether
5136 the PFS is to be performed in the re-key. Affected file is
5139 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5142 int64 of at least the xintXX size. If void * is less that 4
5143 bytes uint32 * will be used. Defined bool as boolean.
5145 * Changed _ALL_ unsigned long and unsigned int to uint32,
5146 unsgined short to uint16 in the source tree.
5148 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5149 not handle clients that has entry->data.registered == FALSE.
5150 They are not in the network anymore. Affected file is
5153 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Implemented the sending of the SERVER_SIGNOFF notify in the
5156 server. Affected file is silcd/server.c.
5158 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5159 Added also silc_notify_payload_encode_args into the
5160 lib/silccore/silcnotify.[ch].
5162 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5163 Affected file silcd/packet_receive.c.
5165 * Implemented the SERVER_SIGNOFF notify handling in the client
5166 library. Affected file lib/silcclient/client_notify.c. Also,
5167 implemnted the printing of the SERVER_SIGNOFF info to the
5168 application. Affected file silc/client_ops.c.
5170 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5171 if the deleting was successful. Affected file silcd/idlist.[ch].
5173 * Added support for public key authentication in the connection
5174 authentication protocol in the client library. Affected file
5175 lib/silcclient/protocol.c.
5177 * Changed the server's silc_idlist_get_clients_by_* interface
5178 to support already allocated array so that new entries may be
5179 added to pre-allocated array. Affected file silcd/idlist.[ch].
5180 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5181 and command replies.
5183 * All command reply functions in the server now calls the
5184 pending command callback even if error occured. This way the
5185 error will be delivered to the client as well. Affected files
5186 silcd/command.c and silcd/command_reply.c.
5188 * Fixed INFO command to return local server's info if no server
5189 was provided. Affected file lib/silcclient/command.c.
5191 * Removed RESTART command for good. Updated the code and the
5194 * Rewrote parts of the task system. It is a bit simpler now.
5195 Removed unsued task priorities. The affected files are
5196 lib/silcutil/silctask.[ch].
5198 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Moved the USERS printing from the library to the application.
5201 Affected files lib/silcclient/command.c and silc/client_ops.c.
5203 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added channel key re-key support. The re-key is perfomed
5208 only by the router and is done once in an hour. Added `rekey'
5209 field to the SilcChannelEntry in the server. Affected files
5210 silcd/server.c and silcd/idlist.h.
5212 * Added silc_task_unregister_by_context into the file
5213 lib/silcutil/silctask.[ch].
5215 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Added SILC_UMODE_GONE mode to indicate when the client is not
5218 present in the SILC network. Added also support to the local
5219 command AWAY that will set this mode. Added support of showing
5220 "xxx is gone" in WHOIS command. The USERS command shows the
5221 gone status as well.
5223 * Fixed setting server and router operator privileges in the
5224 server's UMODE command. Affected file silcd/command.c.
5226 * Merged the SKE KE1 and KE2 payloads into one payload. The
5227 new KE payload is equivalent to the old KE2 payload.
5229 Cleaned up the SKE Start Payload parsing. It now uses the
5230 simple buffer unformatting to do the parsing. A lot faster
5233 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5234 to the SKE that is used to indicate whether both of the SKE
5235 parties should perform authentication. By default only the
5236 responder performs authentication. By setting this flag also
5237 the initiator must do authentication. By default it is unset
5238 since in normal SKE case, client to server connection, only
5239 the responder should do authentication. When doing SKE between
5240 two clients both should perform authentication. Updated the
5241 code and the protocol specs.
5243 * A little fix to IDENTIFY command in the server. Search the
5244 client first by hash not nickname. Affected file is
5247 * Fixed the silc_client_close_connection to support closing
5248 the client to client connections wihtout deleting too much
5249 data. Affected file lib/silcclient/client.c.
5251 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5252 are received if protocol used to be active but is not anymore
5253 the application would crash due to NULL pointer dereference.
5254 Affected files silcd/server.c and lib/silcclient/client.c.
5256 * Added `hash' field to the SilcClientConnection to include
5257 the hash function negotiated in the SKE protocol.
5259 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5260 to set the channel founder authentication data. A client can
5261 claim the founder rights later by providing the authentication
5262 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5263 This way the channel founder can regain the channel founder
5264 privileges even it is left the channel. This works only on
5265 local server and the client must be connected to the same
5266 server to be able to regain the founder rights. Updated the
5267 protocol specs accordingly.
5269 Added support to the CMODE command in the client to set the
5270 founder auth data. Read the README to see how to set it.
5272 Added support to the CUMODE command to claim the founder
5273 rights. Read the README to see how to do it.
5275 Added support for the founder authentication to the Channel
5276 Entry in the server. Affected file silcd/idlist.h.
5278 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5279 server's CMODE command. Affected file silcd/command.c.
5281 * Added the following new functions into lib/silccore/silcauth.[ch]:
5282 silc_auth_get_method and silc_auth_get_data.
5284 * The server now saves the remote hosts public key to the
5285 SilcIDListData pointer. Affected file silcd/protocol.c.
5287 * The normal server now does not remove the channel entry from
5288 the cache if the founder authentication data is set. It used
5289 to remove it if the founder was the last one on the channel on
5290 the server and left the channel. The auth data is saved and
5291 if the channel is re-joined later the old entry is used with
5292 the old auth data. Affected files silcd/command_reply.c and
5295 * Removed the `pkcs' field from the SilcIDListData structure
5296 in the server; it is not used. Affected file silcd/idlist.h.
5298 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Fixed packet processing on slow links. Partial packets were
5301 never re-processed because the incoming data buffer was cleared
5302 by the application. Application must not directly clear the
5303 sock->inbuf, the packet processing routines handle it. Fixed
5304 this in client library and in server.
5306 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Fixed the WHOIS and IDENTIFY send reply function to really
5309 check whether to send list or just one entry. Affected file
5312 * Cleaned up the LEAVE command's channel key distribution. The
5313 affected file silcd/command.c.
5315 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5316 can enforce the channel mode as well. In that case the ID
5317 includes the ID of the server. The code now enforces the
5318 mode change if the router have different mode than the server.
5320 * The notify client operation with CMODE_CHANGE notify can now
5321 return NULL client_entry pointer if the CMODE was not changed
5322 by client. Application must check for this.
5324 * Added <Server ID> argument to INFO command to support server
5325 info fetching by Server ID.
5327 * Added silc_server_announce_get_channel_users to get assembled
5328 packets of channel users of the specified channel. Affected
5329 file silcd/server.[ch].
5331 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5332 was freed underneath the ID Cache.
5334 * Re-announce clients when the server received CHANNEL_CHANGE
5335 notify from the router. Affected file silcd/packet_send.c.
5337 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5340 crashed since it did not handle the fact that there is no cipher
5341 called "3" and didn't check the error condition. Now fixed.
5343 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5344 flag. It can be used to send message requests.
5346 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Implemented the RESTART command in the client.
5350 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5351 notice type messages. Added notice printing to the user
5354 * The channel keys are not re-generated if the channel's mode
5355 is PRIVKEY, ie private key on the channel exists. Affected
5356 files silcd/server.c and silcd/command.c.
5358 * Fixed a little bug in channel message delivery when channel
5359 private keys are set in the server. Affected file is
5360 silcd/packet_send.c.
5362 * Changed the setting on channel->on_channel = TRUE from the
5363 silc_client_save_channel_key to the JOIN command reply. The
5364 key payload is not received if the private channel key is set.
5365 Affected file lib/silcclient/command_reply.c and the
5366 lib/silcclient/client_channel.c.
5368 * When the CMODE_CHANGE notify is sent and the channel private
5369 key mode is removed the channel key must be re-generated in
5370 other cells as well. Added this support for the router in the
5371 silcd/packet_receive.c.
5373 * Added new local command NOTICE to send notice message on
5374 channel. Affected file silc/local_command.[ch].
5376 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Added new local command ME to the client. It is used to send
5379 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5380 some action. Affected file silc/local_command.[ch].
5382 * Changed channel_message and private_message client operations
5383 to deliver the message flags to the application. Added also
5384 the `flags' arguments to the silc_client_send_channel_message
5385 and silc_client_send_private_message functions. Affected file
5388 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Redefined the Private Message Payload to support private message
5391 keys and to support the new private message flags. Updated
5392 the protocol specs. Flags makes it possible to have for example
5393 CTCP style messages.
5395 * Added new type SilcPrivateMessagePayload and defined an API
5396 for it in the lib/silcclient/silcprivate.[ch].
5398 * Tested private message private keys successfully. Tested the
5399 private message key set, unset and list commands with the new
5402 * Redefined the Channel Message Payload to include the channel
5403 message flags (equal with private message flags) to support
5404 for example CTCP style messages.
5406 * Defined some of the message (for channel and private message)
5407 flags. Updated the protocol specs and added the flags to the
5408 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5410 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Added SilcKeyAgreementStatus type to the key agreement routines
5413 to indicate the current status and error if one occured.
5414 The status types are defined in the lib/silcclient/silcapi.h.
5416 * Added new local command KEY that is used to set and unset private
5417 keys for channels, set and unset private keys for private messages
5418 with remote clients and to send key agreement requests and
5419 negotiate the key agreement protocol with remote client. The
5420 key agreement is supported only to negotiate private message keys,
5421 it currently cannot be used to negotiate private keys for channels,
5422 as it is not convenient for that purpose.
5424 * Fixed a minor pending callback setting bug in the function
5425 silc_client_get_client_by_id_resolve, now the function works.
5426 Affected file lib/silcclient/idlist.c.
5428 * Added function silc_net_get_local_port to get local bound
5429 port by socket. Added to lib/silcutil/silcnet.[ch].
5431 * Added `sockets' and `sockets_count' fields to the SilcClient
5432 object. They hold the sockets of the listenning sockets in
5433 the client. Listenning sockets may be for example the key
5434 agreement server. Affected file lib/silcclient/client.[ch].
5435 Added functions the silc_client_add_socket and the
5436 silc_client_del_socket. They are exported to the application
5439 * Added ~./silc/clientkeys to support other client's public keys.
5441 * Renamed verify_server_key client operation to verify_public_key
5442 and added one argument to indicate the type of the connection
5443 (server, client etc.).
5445 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added silc_server_connection_auth_request to handle the
5448 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5449 silcd/packet_receive.[ch].
5451 * Added silc_server_send_connection_auth_request into the
5452 silcd/packet_send.c to send the connection auth request packet.
5454 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5457 * Fixed the public key authentication in responder side in the
5458 server. The `auth_data' pointer includes the SilcPublicKey
5459 not the path to the public key. Affected file silcd/protocol.c.
5461 * Implemented the public key authentication in the initiator side
5462 in the server. Affected file silcd/protocol.c.
5464 * Removed the [RedirectClient] config section from the server
5465 configuration. Is not needed and I don't want to implement it.
5467 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Cleaned up the CMODE command in the server. It now works
5470 correctly and supports all the modes defined in the protocol.
5471 Affected file is silcd/command.c.
5473 * Added `hmac_name' field to the SilcChannelEntry in the server
5474 to hold the default HMAC of the channel. It can be set when
5475 creating the channel (with JOIN command). Affected files
5478 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5479 type to indicate the change of the current cipher and hmac
5480 on the channel. Client can safely ignore the <cipher> argument
5481 (if it chooses to do so) since the CHANNEL_KEY packet will
5482 force the channel key change anyway. The <hmac> argument is
5483 important since the client is responsible of setting the new
5484 HMAC and the hmac key into use.
5486 * Fixed the CMODE command in the client library as well.
5488 * Tested CMODE command in router environment successfully.
5490 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Show the version of the remote client (or server) when connecting
5493 to the server. It is logged to the log file. Affected file
5494 is silcd/protocol.c.
5496 * Fixed the KILLED notify handling in the client library. The
5497 client must be removed from all channels when receiving the
5500 Also, do not remove the client entry when giving the KILL
5501 command but when the KILLED notify is received.
5503 * Removed silc_idlist_find_client_by_nickname from the server.
5504 Not needed anymore. Affected files silcd/idlist.[ch].
5506 * Implemented the CHANNEL_CHANGE notify type handling to the
5507 server. Affected file silcd/server.c.
5511 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added silc_server_send_notify_invite to send the INVITE
5514 notify between routers.
5516 * Implemented the INVITE command correctly to the server.
5518 * Implemented the INVITE notify type handling in the server.
5520 * Implemented the INVITE command to the client library and on the
5523 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added function silc_server_get_client_resolve to find the
5526 client entry by ID from all ID lists and then resolve it
5527 (using WHOIS) if it cannot be found. Affected file is
5530 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Implemented the BAN command to the client library.
5534 * The JOIN command in the server now checks the invite list
5537 * Changed the silc_command_reply_payload_encode_va and the
5538 silc_command_payload_encode_va to support that if argument is
5539 NULL it ignores and checks the next argument. Affected file
5540 lib/silccore/silccommand.c.
5542 * Added silc_server_send_notify_ban to send the BAN notify
5543 type between routers.
5545 * Chaned the silc_notify_payload_encode to support that if
5546 argument is NULL it ignores and checks the next argument.
5547 Affected file lib/silccore/silcnotify.c.
5549 * Tested ban lists in router environment successfully.
5551 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Implemented BAN command to the server, in silcd/command.[ch].
5555 * Removed the BAN and INVITE_LIST modes from the CMODE command
5558 * Added function silc_string_match to regex match two strings.
5559 Affected files lib/silcutil/silcutil.[ch].
5561 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Redefined parts of the SilcChannelEntry in the server to support
5564 the new ban and invite lists.
5566 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Redefined the INVITE command. The same command can be used to
5569 invite individuals to the channel but also to manage the invite
5570 list of the channel (to add to and remove from the invite list).
5571 Updated the protocol specs.
5573 * Added new command SILC_COMMAND_BAN that can be used to manage
5574 the ban list of the channel. Updated the protocol specs.
5576 * Removed the channel modes: the SILC_CMODE_BAN and the
5577 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5578 in the CMODE command. The equivalent features are now available
5579 using INVITE and BAN commands. Updated the protocol specs.
5581 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5582 in the network about change in the current ban list. The notify
5583 type is not used by the client.
5585 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5586 support the invite lists.
5588 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added new function silc_string_regexify that converts string
5591 including wildcard characters into regex string that can
5592 be used by the GNU regex library. Added into the file
5593 lib/silcutil/silcutil.[ch].
5595 Added silc_string_regex_combine to combine to regex strings
5596 into one so that they can be used as one regex string by
5597 the GNU regex library. Added into the file
5598 lib/silcutil/silcutil.[ch].
5600 Added silc_string_regex_match to match two strings. It returns
5601 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5603 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Imported GNU regex to the soruce tree into lib/contrib.
5606 Fixed some compiler warning from the regex.c.
5608 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Fixed MOTD command in the server to work in router environment.
5612 * Fixed the MOTD command in the client library to support
5613 the server argument in the command.
5615 * Added `nickname_len' argument to the silc_idlist_add_client
5616 in the server, as the `nickname' argument may be binary data
5619 * Added silc_idlist_get_channels to return all channels from
5622 * Implemented LIST command to the server. Affected file is
5625 * Implemented the LIST command to the client library and on the
5628 * Added [<user count>] argument to the LIST command reply.
5629 With private channels the user count is not shown.
5631 * Updated TODO and README.
5633 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * The client entry's data.registered must be TRUE even with
5636 global client entry on global client list. The data.registered
5637 is used to check whether the client is anymore in the network,
5638 for example with WHOWAS command so it must be valid.
5640 * Fixed the WHOWAS command in the server. It now actually works
5641 in router environment. Added function into silcd/command_reply.c
5642 silc_server_command_reply_whowas_save.
5644 * Added silc_idlist_purge function to the silcd/idlist.c
5645 to periodically purge the ID Cache.
5647 * Fixed INFO command in the server. It works now in router
5648 environment. Added <server name> argument to the INFO command
5649 reply. Updated the protocol specs.
5651 * Fixed minor bug in silc_idcache_purge to not purge if the
5652 expire value is zero.
5654 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5655 they were buggy because of the WHOWAS information.
5657 * Fixed local command MSG to handle the async resolving of
5658 the remote client properly. It used to fail the first MSG.
5659 Affected file silc/local_command.c.
5661 * Added `data_len' field to SilcIDCache context.
5663 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Update TODO. Todo in commands in the server.
5667 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5670 used by routers as broadcast packet to inform other routers
5671 about the changed user mode.
5673 Implemented the notify handling in the server. Affected file is
5674 silcd/packet_receive.c. Added the function
5675 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5677 * Added new generic Channel Payload and deprecated the New Channel
5678 Payload. The New Channel Payload is now the generic Channel
5681 * Added new argument `mode' to the silc_server_send_new_channel
5682 as it is required in the Channel Payload now.
5684 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5685 and created a new and real SilChannelPayload to represent the
5686 new generic Channel Payload. Implemented the encode/decode
5687 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5689 * Added silc_server_get_client_channel_list to return the list
5690 of channels the client has joined for WHOIS command reply.
5691 Affected file silcd/server.[ch].
5693 * Implemented the channel list sending in the WHOIS command reply
5694 in server and in the client.
5696 Implemented the channel list displaying on the user interface
5697 as well. Affected file silc/client_ops.c.
5699 * Added silc_channel_payload_parse_list to parse list of Channel
5700 Payloads. It returns SilcDList list of SilcChannelPayloads.
5701 Client for example can use this function to parse the list of
5702 channels it receives in the WHOIS command reply. The caller
5703 must free the list by calling silc_channel_payload_list_free.
5704 Affected files lib/silccore/silcchannel.[ch].
5706 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added one new argument <user mode> to the WHOIS command reply
5709 to return the mode of the user in SILC. Updated the protocol
5712 Implemented it to the server and client.
5714 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Fixed the mode printing on the user interface on joining.
5717 Affected file silc/client_ops.c.
5719 * Implemented the UMODE command and user modes in general to the
5720 client library and to the user interface.
5722 * Implemented the UMODE command to the server.
5724 * The server now sends UNKNOWN_COMMAND error status if client sends
5725 unknown command. Affected file silcd/command.c.
5727 * All server commands now handle the command identifier the right
5728 way when sending the command reply to the client. The client can
5729 use to identify the command replies with the identifier.
5731 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Added silc_server_get_client_route to resolve the route to
5734 the client indicated by the client ID. Affected file is
5737 * Added silc_server_relay_packet as general function to relay
5738 packet to arbitrary destination. This deprecates functions
5739 like _send_private_message_key, _relay_notify etc. Affected
5740 file is silcd/packet_send.[ch].
5742 Removed silc_server_send_key_agreement,
5743 silc_server_send_private_message_key and
5744 silc_server_packet_relay_notify functions from the file
5745 silcd/packet_send.[ch].
5749 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5750 server. Affected file silcd/packet_receive.[ch].
5752 * Implemented the KILL command to the client. Implemented the
5753 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5754 Affected files lib/silcclient/command[_reply].c and
5755 lib/silcclient/client_notify.c. Implemented the KILL notify
5756 printing in the user inteface.
5758 * Fixed a lot silc_parse_nick memory leaks from the client
5759 library in the file lib/silcclient/command.c.
5761 * Changed the silc_server_send_notify_on_channels's `sender'
5762 argument from SilcSocketConnection to SilcClientEntry to
5763 check the sender as entry and not as connection object and not
5764 to send to the client provided as argument. The affected file
5765 is silcd/packet_send.[ch].
5767 * The notify packets that are destined directly to the client used
5768 to not to be processed by the server. Now changed that and the
5769 server processes all notify packets. After relaying the packet
5770 to the client the notify packet is processed in the server.
5772 * The silc_server_free_client_data now checks whether there is
5773 pending outgoing traffic for the client and purges the data to
5774 the network before removing the client entry.
5776 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5779 an client is killed from the SILC Network. Updated the protocol
5782 Added new function silc_server_send_notify_killed to the
5783 silcd/packet_send.[ch].
5785 * Added function silc_server_packet_relay_notify to relay notify
5786 packets that are destined directly to a client. In this case
5787 the server does not process the notify packets but merely relays
5788 it to the client. Affected file silcd/packet_send.[ch].
5790 Added also silc_server_packet_process_relay_notify to check
5791 whereto relay the notify. Affected file is
5792 silcd/packet_receive.[ch].
5794 * Implemented the KILL command to the server.
5798 * Added the backup schema desgined last fall to the protocol
5799 specs for everyone to see. The specification is in the
5800 *-spec-xx.txt draft and the packet type definitions for the
5801 backup routers is in *-pp-xx.txt draft. Thusly, added also
5802 new packet type SILC_PACKET_CELL_ROUTERS.
5804 * A big security problem in the implementation discovered. The
5805 signoff of an client did not cause new channel key generation
5806 which it of course should've done. The channel keys must be
5807 always re-generated when client leaves (or signoffs) the channel.
5808 The silc_server_remove_from_channels funtion now handles
5809 the channel key re-generation.
5811 * Added `sender' argument to the silc_server_send_notify_on_channels
5812 to not to send the client provided as argument. Affected file
5813 silcd/packet_send.[ch].
5815 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Implemented OPER and SILCOPER commands into the server and
5820 * Added silc_auth_verify and silc_auth_verify_data to verify
5821 the authentication directly from the authentication payload.
5822 It supports verifying both passphrase and public key based
5823 authentication. Affected file lib/silccore/silcauth.[ch].
5825 * Added `hash' field to the SilcIDListData structure. It is the
5826 hash negotiated in the SKE protocol. Affected file is
5829 * Slight redesigning of the SilcAuthPayload handling routines.
5830 Do not send SilcPKCS but SilcPublicKey as argument.
5832 * Implemented the public key authentication support to the
5833 serverconfig. The public key is loaded from the provided path
5834 and saved as authentication data to void * pointer. Thus,
5835 changed the unsigned char *auth_data to void *auth_data;
5837 * Fixed SHUTDOWN command to send the reply before the server
5838 is shutdown. :) Affected file silcd/command.c.
5840 * Fixed fatal bug in CONNECT command. The hostname was invalid
5841 memory and server crashed. Affected file silcd/command.c.
5843 * Fixed fatal bug in CLOSE command. The server_entry became
5844 invalid but was referenced later in the command. Affected file
5847 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Fixed fatal bug in failure packet handling. Server ignored
5850 the failure and thus crashed when it came.
5854 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5857 that the command may be executed only once in (about) 2 seconds.
5858 The old SILC_CF_LAG flag is same but allows command bursts up
5859 to five before limiting.
5861 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5862 server code. Various commands now includes the CF_LAG_STRICT
5863 flag to disallow any kind of miss-use of the command.
5865 * Fixed the silc_buffer_unformat to not to allocate any data
5866 if the length of the data is zero. It used to allocate the
5867 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5869 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Changed the format of AdminConnection configuration section
5872 in the server. Added username of the admin to the format.
5873 Affected files silcd/serverconfig.[ch].
5875 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5876 to return admin configuration data by host, username and/or
5879 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Implemented WHOWAS command to the server. Added the functions:
5883 silc_server_command_whowas_parse,
5884 silc_server_command_whowas_send_reply,
5885 silc_server_command_whowas_from_client and
5886 silc_server_command_whowas_from_server
5888 * Added <Client ID> argument to the WHOWAS command reply. Updated
5889 the protocol specs accordingly.
5891 * Implemented WHOWAS command and command_reply to the client
5894 Implemented the WHOWAS printing on the user interface.
5896 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Added new argument to the WHOWAS command reply, the real name.
5899 It is an optional argument. Updated the protocol specs.
5901 * Added SilcIDCacheDestructor callback that is registered when
5902 the SilcIDCache is allocated. The callback is called when
5903 an cache entry in the ID Cache expires, or is purged from the
5904 cache. Added into lib/silccore/idcache.[ch].
5906 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5907 to destruct the client entries when the cache entry expires.
5908 Other ID Cache's in server and in the client library ignores
5911 * If the ID Cache entry's `expire' field is zero then the entry
5912 never expires. Added boolean `expire' argument to the
5913 silc_idcache_add function in the lib/silccore/idcache.[ch].
5914 If it is TRUE the default expiry value is used.
5916 * Added silc_server_free_client_data_timeout that is registered
5917 when client disconnects. By default for 5 minutes we preserve
5918 the client entry for history - for WHOWAS command.
5920 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Added support to the server to enforce that commands are not
5923 executed more than once in 2 seconds. If server receives
5924 commands from client more frequently, timeout is registered
5925 to process the commands. Affected file silcd/command.c.
5926 Added new function silc_server_command_process_timeout.
5928 * Changed NICK_NOTIFY handling in client library to check that
5929 if the client's nickname was changed, so there is no need to
5930 resolve anything from the server.
5932 * Removed error printing from the WHOIS and IDENTIFY commands.
5933 If error occurs then it is ignored silently in the client library.
5934 The application, however, may map the received error to
5935 human readable error string. The application currently maps
5936 the NO_SUCH_NICKNAME error to string.
5938 * Made the command status message public to the application. Moved
5939 them from lib/silcclient/command_reply.c to
5940 lib/silcclient/command_reply.h. The application can map the
5941 received command status to the string with the
5942 silc_client_command_status_message function.
5944 * Added check to the server to check that client's ID is same
5945 as the Source ID in the packet the client sent. They must
5948 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Added dist-bzip hook to the Makefile.am to make bzip2
5951 compressed distributions.
5953 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Server now enforces the maximum length for the nickname and
5956 the channel as protocol specification dictates. 128 bytes for
5957 nickname and 256 bytes for channel name.
5959 * Moved the WHOIS printing to the application. The client libary
5960 does not print out the WHOIS information anymore, the application
5961 must do it. Renamed silc_client_command_reply_whois_print to
5962 the silc_client_command_reply_whois_save.
5964 The client's idle time is also sent to the application now, and
5965 the idle is shown on screen.
5967 * Added silc_client_command_reply_identify_save to save the
5968 received IDENTIFY entries.
5970 * Do not check for channel private keys in message sending and
5971 reception if the channel does not have the PRIVKEY mode set.
5972 Affected file lib/silclient/client_channel.c.
5974 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5977 just surfaced after chaning the JOIN procedure.
5979 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Added silc_client_get_clients_by_list to get client entries
5982 from Client ID list, that is returned for example by JOIN
5983 and USERS command replies. The application should use this
5984 function for example when JOIN command reply is received to
5985 resolve the clients already on the channel (library does not
5986 do that anymore as USERS command reply is not used in the JOIN
5987 procedure anymore). Affected files lib/silcclient/silcapi.h and
5988 lib/silcclient/idlist.c.
5990 * JOIN command reply and USERS command reply returns now SilcBuffer
5991 pointers instead of unsigned char pointers when returning
5992 the client list and mode list.
5994 * Added <Client ID> argument to the JOIN command reply, mainly
5995 for the server to identify for which client the command was
5996 originally sent. Updated protocol specs accordingly.
5998 * Added SilcDlist private_key pointer to the SilcChannelEntry
5999 in the client to support the channel private keys. Affected
6000 file is lib/silcclient/idlist.h.
6002 * Added SilcChannelPrivateKey argument to the function
6003 silc_client_send_channel_message so that application can choose
6004 to use specific private ke if it wants to. If it is not provided,
6005 the normal channel key is used, unless private keys are set.
6006 In this case the first (key that was added first) is used
6007 as the encryption key.
6009 * Implemented the support for channel private key handling.
6010 Implemented the following functions:
6012 silc_client_add_channel_private_key,
6013 silc_client_del_channel_private_keys,
6014 silc_client_del_channel_private_key,
6015 silc_client_list_channel_private_keys and
6016 silc_client_free_channel_private_keys
6018 Affected file lib/silcclient/client_channel.c.
6020 * Added the support for the private keys in the channel message
6021 sending and encryption and in the message reception and
6022 decryption. Affected funtions are
6023 silc_client_send_channel_message and silc_client_channel_message.
6025 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added SKE's key verify callback to the client library's
6028 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6030 * Removed the statement that server (or router) must send USERS
6031 command reply when joining to the channel so that the client
6032 knows who are on the channel. Instead, the client list and
6033 client's mode list is now sent in the JOIN command reply to the
6034 client who joined channel. This is better solution.
6036 * Added function silc_server_get_users_on_channel and function
6037 silc_server_save_users_on_channel to the silcd/server.[ch].
6039 * Removed function silc_server_command_send_users from the
6042 * Do not show topic on the client library anymore. The topic is
6043 sent in the command reply notify to the application and the
6044 application must show the topic now.
6046 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Added client searching by nickname hash into the IDENTIFY and
6049 WHOIS commands in the server as they were clearly missing from
6050 them. Affected file is silcd/command.c.
6052 * Fixed a bug in private message receiving in the client library.
6053 The remote ID was freed and it wasn't supposed, now it is
6056 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Minor fix to the channel payload; allocate the data area, as it
6059 needs to be of specific length.
6061 * If the key agreement port is zero then the operating
6062 system will define the bound port. Affected files are
6063 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6065 * Added new function silc_channel_payload_decrypt into the file
6066 lib/silccore/silcchannel.[ch].
6068 * Moved the channel message etc, check from silc_packet_decrypt
6069 to applications. The library calls now a generic
6070 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6071 when the packet is either normal or special. This was done to
6072 allow more wide range of checking that was not allowed when
6073 the code was in library. Now applications can do virtually any
6074 checks to the packet and return to the library the decision how
6075 the packet should be processed. Affected files are
6076 lib/silccore/silcpacket.[ch].
6078 Added silc_server_packet_decrypt_check to the server and
6079 silc_client_packet_decrypt_check to the client library.
6081 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6082 to send with specified source and destination information.
6084 * Channel message delivery between routers was broken after the
6085 channel key distribution was fixed earlier. The channel key
6086 was used be to distributed to other routers as well which is not
6087 allowed by the protocol. Now this is fixed and channel keys
6088 really are cell specific and the channel message delivery between
6089 routers comply with the protocol specification.
6091 * Fixed various commands in server to check also the global list
6092 for the channel entry and not just the local list. The affected
6093 file silcd/command.c.
6095 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Added assert()s to buffer formatting and unformatting routines
6098 to assert (if --enable-debug) when error occurs. Affected
6099 file: lib/silcutil/silcbuffmt.c.
6101 * Changed to auto-reconnect to check whether the remote host is
6102 router and register the re-connect timeout if it is. It used
6103 to check that whether we are normal server, but router must do
6104 auto-reconnect with another router as well. Affected file
6107 * Removed the [<key len>] option from CMODE command as the cipher
6108 name decides the key length, nowadays. See the defined ciphers
6109 from the protocol specification.
6111 * Added [<hmac>] option to the CMODE command to define the HMAC
6112 for the channel. Added SILC_CMODE_HMAC channel mode.
6114 * Added [<hmac>] option for the JOIN command so that user can
6115 select which HMAC is used to compute the MACs of the channel
6118 * Added Hmac field to the Channel Message Payload. The integrity
6119 of plaintext channel messages are now protected by computing
6120 MAC of the message and attaching the MAC to the payload. The
6121 MAC is encrypted. Now, it is clear that this causes some
6122 overhead to the size of the packet but rationale for this is that
6123 now the receiver can verify whether the channel message decrypted
6124 correctly and also when private keys are set for the channel the
6125 receiver can decrypt the packet with several keys and check from
6126 the MAC which key decrypted the message correctly.
6128 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6129 lib/silccrypt/silccipher.[ch].
6131 * Added silc_hash_len to return the digest length into the
6132 lib/silcrypt/silchash.[ch].
6134 * Rewrote parts of Silc Channel Payload interface in the
6135 lib/silccore/silcchannel.[ch]. The encode function now also
6136 encrypts the packet and parse function decrypts it.
6138 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Fixed a minor formatting bug in the SKE's key material processing.
6141 It actually might have processed the keys wrong way resulting
6144 * Redefined the mandatory HMAC algorithms and added new algorithms.
6145 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6146 and hmac-md5 truncated to 96 bits. The mandatory is now
6147 hmac-sha1-96. Rest are optional (including the one that used
6148 to be mandatory). Rationale for this is that the truncated HMAC
6149 length is sufficient from security point of view and can actually
6150 make the attack against the HMAC harder. Also, the truncated
6151 HMAC causes less overhead to the packets. See the RFC2104 for
6154 * Added new [hmac] configuration section. The SKE used to use
6155 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6156 is of course wrong. The official names that must be proposed in
6157 the SKE are the ones defined in the protocol specification
6158 (hmac-sha1-96 for example). The user can configure any hmac
6159 using any hash function configured in the [hash] section. At
6160 least, the mandatory must be configured.
6162 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6164 * Added HMAC list to the SKE proposal list. It has now both
6165 hash algorithm list and HMAC list. This makes the protocol
6166 incompatible with previous versions. The SKE now seems to work
6167 the way it is supposed to work, for the first time actually.
6169 * Defined plain Hash algorithms to the protocol specification.
6172 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Implemented support for key agreement packets into the server.
6175 Added functions silc_server_key_agreement and
6176 silc_server_send_key_agreement. Other than these functions,
6177 server has nothing to do with this packet.
6179 * Added support for private message key packets into the server.
6180 Added functions silc_server_private_message_key and
6181 silc_server_send_private_message_key.
6185 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6186 called in the protocol's final callback instead in the END
6187 protocol state. This makes a little more sense and in the same
6188 time in client we can use the same protocol routines for normal
6189 key exchange and to key agreement packet handling as well.
6191 * Added to both client's and server's KE protocol context the
6192 SilcSKEKeyMaterial pointer to save the key material. We will
6193 bring the key material to the protocol's final callback by doing
6194 this. The final callback must free the key material.
6196 * Added SKE's packet_send callback into client's KE protocol
6197 context so that the caller can choose what packet sending function
6198 is used. This way we can use different packet sending when
6199 doing normal SKE when doing key agreement packet handling (in
6200 the key agreement packet handling we do not want to encrypt
6203 * Implemented the responder side of the key agreement routines
6204 in the client. The client can now bind to specified port and
6205 accept incoming key negotiation. The key material is passed
6206 to the application after the protocol is over.
6208 * Implemented the processing of incoming Key Agreement packet
6209 in the client. Added function silc_client_key_agreement to
6212 * Implemented the intiator side of the key agreement routines
6213 in the client. The client can now initiate key agreement with
6214 another remote client. The key material is passed to the
6215 application after the protocol is over.
6217 * Created client_keyagr.c to include all the key agreement
6220 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6221 SILC_TASK_CALLBACK except that it is not static.
6223 * Created client_notify.c and moved the Notify packet handling
6224 from the client.[ch] into that file.
6226 * Created client_prvmsg.c and moved all private message and
6227 private message key routines from the client.[ch] into that file.
6229 * Create client_channel.c and moved all channel message and
6230 channel private key routines from the client.[ch] into that file.
6232 * Changed silc_client_get_client_by_id_resolve to resolve with
6233 WHOIS command instead of IDENTIFY command, in the file
6234 lib/silclient/idlist.c.
6236 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Implemented the SKE's responder side to the Client library.
6240 * When FAILURE is received to the protocol do not trust it
6241 blindly. Register a timeout to wait whether the remote closes
6242 the connection as it should do it, only after that process the
6243 actual failure. This was changed to both client and server.
6245 * Added client_internal.h to include some of the structures
6246 there instead of client.h in lib/silcclient/.
6248 * Added function silc_task_unregister_by_callback to unregister
6249 timeouts by the callback function.
6251 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Some "Incomplete WHOIS info" errors has been appearing on the
6254 log files. Took away the entry->userinfo check from WHOIS
6255 reply sending. The entry->userinfo is now " " if client did not
6256 provide one. I thought this was fixed earlier but something
6257 is wrong still. Let's see if the error still appears.
6259 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Fixed a minor bug in the login when the channel key is
6262 re-generated in the server. It used to generate the key in
6263 wrong order and thus caused problems in the channel traffic.
6265 * Fixed a minor bug in channel key distsribution after
6266 KICK command. The key was not sent to the router even though
6269 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Added silc_ske_process_key_material_data as generic routine
6272 to process any key material as the SILC protocol dictates. The
6273 function is used by the actual SKE library but can be used by
6274 applications as well. This relates to the private message keys
6275 and the channel private keys since they must be processed the
6276 same way the normal SILC session keys. The protocol dictates
6277 this. Affected files: lib/silcske/silcske.[ch].
6279 Added also silc_ske_free_key_material to free the
6280 SilcSKEKeyMaterial structure.
6282 * Defined silc_cipher_set_key function to set the key for
6283 cipher without using the object's method function. The affected
6284 files: lib/silccrypt/silccipher.[ch].
6286 * Implemented silc silc_client_add_private_message_key,
6287 silc_client_add_private_message_key_ske,
6288 silc_client_del_private_message_key,
6289 silc_client_list_private_message_keys and
6290 silc_client_free_private_message_keys functions in the
6293 Added functions silc_client_send_private_message_key to send
6294 the Private Message Key payload and silc_client_private_message_key
6295 to handle incoming Private Message Key payload.
6297 * Added Cipher field to the Private Message Key payload to set
6298 the cipher to be used. If ignored, the default cipher defined
6299 in the SILC protocol (aes-256-cbc) is used.
6301 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Removed lib/silcclient/ops.h file.
6305 Redefined parts of the SILC Client Library API. Created new
6306 file silcapi.h that deprecates the ops.h file and defines the
6307 published Client Library API. Defined also private message key
6308 API and channel private key API into the file.
6310 This is the file that the application must include from the
6311 SILC Client Library. Other files need not be included by
6312 the application anymore.
6314 * Added new key_agreement client operation callback and also
6315 defined the Key Agreement library API for the application.
6317 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6320 is used by clients to request key negotiation between another
6321 client in the SILC network. If the negotiation is started it
6322 is performed using the SKE protocol. The result of the
6323 negotiation, the secret key material, can be used for example
6324 as private message key.
6326 Implemented the Key Agreement payload into the files
6327 lib/silccore/silauth.[ch].
6329 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Redefined ciphers for the SILC protocol. Added some new ciphers
6332 and defined the key lengths for the algorithms. Changed the
6333 code accordingly. The default key length is now 256 bits.
6335 * Fixed SKE key distribution function silc_ske_process_key_material
6336 when the key length is more than 128 bits. The default key
6337 length in SILC is now 256 bits.
6339 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6340 to indicate unsupported algorithm.
6342 * Renamed rijndael.c to aes.c and all functions as well.
6344 * Fixed a long standing channel key setting bug in client library.
6345 Weird that it has never surfaced before.
6347 * Fixed bug in channel deletion. If the entire channel is removed
6348 then it must also delete the references of the channel entry
6349 from the client's channel list as the client's channel entry and
6350 the channel's client entry share same memory.
6352 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Implemented CONNECT and SHUTDOWN commands in the client.
6356 * Implemented CLOSE command to the client.
6358 * Added the function silc_idlist_find_server_by_name into the
6359 files silcd/idlist.[ch].
6361 Added the function silc_idlist_find_server_by_conn into the
6362 files silcd/idlist.[ch].
6364 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * DIE command was renamed to SHUTDOWN. Updated the both code
6369 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6370 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6372 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6375 * Added function silc_server_create_connection function to create
6376 connection to remote router. My server implementation actually
6377 does not allow router to connect to normal server (it expects
6378 that normal server always initiates the connection to the router)
6379 so the CONNECT command is only good for connecting to another
6382 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6385 or some other client was kicked from the channel.
6387 Implemented the handling of the notify type to both client
6390 Implemented silc_server_send_notify_kicked to send the KICKED
6391 notify. It is used to send it to the server's primary router.
6393 * Implemented the KICK command into server and client.
6395 * Added `query' argument to the silc_idlist_get_client function
6396 to indicate whether to query the client from server or not if
6399 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6400 to indicate that the client is not channel founder.
6404 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Removed the rng context from SilcPacketContext structure and
6407 changed that the packet routine uses the Global RNG API.
6409 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Added support for quit message that client can "leave" on the
6412 channel when it quits the SILC. It is ditributed inside the
6413 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6415 Added silc_server_free_client_data that will take the
6416 signoff message as argument.
6418 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6420 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Updated parts of the protocol specification to keep it up
6425 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6427 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6428 payloads in one packet.
6430 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6431 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6432 use now the new List flag.
6434 * Also deprecated the following packet types: REPLACE_ID,
6435 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6437 * Added list support for Notify packet in server.
6439 * Added silc_server_send_notify_channel_change to send the
6440 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6441 the silc_server_send_replace_id.
6443 * Added silc_server_send_notify_nick_change to send the
6444 NICK_CHANGE notify type. Deprecates the function
6445 silc_server_send_replace_id.
6447 * Added silc_server_send_notify_join to send the JOIN notify type.
6448 Deprecates the function silc_server_send_new_channel_user.
6450 * Added silc_server_send_notify_leave to send LEAVE notify type.
6451 Deprecates the function silc_server_send_remove_channel_user.
6453 * Added silc_server_send_notify_cmode and
6454 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6455 types. Deprecates the silc_server_send_set_mode function.
6457 * Added SERVER_SIGNOFF notify type to indicate that server has
6458 quit. This means that all clients on the channel from that
6459 server will drop. This can be also used when netsplit happens.
6461 Deprecated REMOVE_ID packet type since it is not needed anymore
6464 Added silc_server_send_notify_server_signoff to send the
6465 SERVER_SIGNOFF notify type. Deprecates the function
6466 silc_server_send_remove_id.
6468 Added also silc_server_send_notify_signoff to send the
6469 SIGNOFF notify type.
6471 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6472 SILC protocol from this day on. Changed the protocol
6473 specification as well.
6475 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6476 notify type. It is used between routers to notify about
6477 topic changes on a channel.
6479 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6482 * Partly updated the protocol specification to comply with the
6483 changes now made. It is still though a bit outdated.
6485 * The JOIN notify type now takes one extra argument <Channel ID>.
6486 The packet used to be destined to the channel but now the
6487 JOIN type may be sent as list thus it is impossible to
6488 destine it to any specific channel. By adding this argument
6489 it is again possible.
6491 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Added CREDITS file. The CHANGES and CREDITS file will appear
6494 in the distribution as well.
6496 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6499 types in the server's silcd/packet_receive.c.
6501 * Implemented CMODE and CUMODE to work in router environment.
6503 * Fixed minor encoding and decoding buglet from the
6504 lib/silccore/silcmode.c.
6506 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6509 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6511 * Changed all SilcConfigServer* and silc_config_server* to
6512 SilcServerConfig* and silc_server_config*, respectively.
6515 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Associated the ID (client or server ID) to the Authentication
6518 Payload to avoid any possibility of forging. Updated the
6519 protocol specification and the code accordingly.
6521 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * The RSA key length is now save to the RsaKey context in the
6524 key generation process in lib/silccrypt/rsa.c. The key length
6525 is now used to figure out the maximum size of the block allowed
6526 to be encrypted/signed.
6528 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6529 is equivalent to the silc_mp_mp2bin but does not allocate any
6532 * Changed silc_mp_mp2bin API to take length argument. If it is
6533 non-zero then the buffer is allocated that large. If zero, then
6534 the size is approximated using silc_mp_sizeinbase, which however
6537 * Created Global RNG API which is global RNG that application can
6538 initialize. After initializing, any routine anywhere in the
6539 code (including library) can use RNG without allocating a new
6540 RNG object. This was done to allow this sort of use of the
6541 RNG in code that has no chance to allocate RNG object. All
6542 applications currently allocate this and many routines in the
6543 library use this. Affected file lib/silccrypt/silcrng.[ch].
6545 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6546 it to use the Global RNG API.
6548 * Defined Authentication Payload into protocol specification that
6549 is used during SILC session to authenticate entities. It is
6550 used for example by client to authenticate itself to the server
6551 to obtain server operator privileges.
6553 Implemented this payload into the lib/silccore/silcauth.[ch].
6554 Implemented also routines for public key based authentication
6555 as the new protocol specification dictates.
6557 Moved definitions of different authentication methods from
6558 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6560 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6561 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6562 silc_pkcs_verify_with_hash functions into the file
6563 lib/silccrypt/silcpkcs.[ch].
6565 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * The client entry's userinfo pointer must be always valid.
6568 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6569 will fail since it requires the userinfo. Now, the userinfo
6570 is allocated as "" if actual userinfo does not exist. Actually,
6571 it must exist and it is totally Ok to drop client connections
6572 that does not announce the userinfo. However, we will make
6573 this workaround for now.
6575 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6576 to return the remote port by socket.
6578 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6581 SILC_SERVER_PENDING_EXEC and added an new macro
6582 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6583 data or when error occurs while processing the pending command.
6585 Added new argument `destructor' into silc_server_command_pending
6586 and to the SilcServerCommandPending object. This destructor is
6587 now called after calling the pending callback or if error occurs
6588 immediately. If error occurs the actual pending callback won't
6589 be called at all - only the destructor. The destructor may be
6590 NULL if destructor is not needed.
6592 All this applies for client library code as well. Similar
6593 changes were made there as well for the pending commands.
6595 In the client, the application must now allocate the
6596 SilcClientCommandContext with the silc_client_command_alloc
6599 * Added reference counter to the SilcServerCommandContext. Added
6600 function silc_server_command_alloc and silc_server_command_dup
6603 Same type of functions added to the client library for the same
6606 * Removed the cmd_ident from IDListData away since it is now
6607 global for all connections. It is the command identifier used
6608 in command sending and with pending commands. The affected file
6611 * Added reference counter to the SilcSocketConnection objecet to
6612 indicate the usage count of the object. The object won't be
6613 freed untill the reference counter hits zero. Currently only
6614 server uses this, and client ignores it. The client must be
6615 set to use this too later. The affected files are
6616 lib/silccore/silcsockconn.[ch]. Added also the function
6617 silc_socket_dup to increase the reference counter.
6619 This was mainly added because it is possible that the socket
6620 is removed underneath of pending command or other async
6621 operation. Now it won't be free'd and proper DISCONNECTING
6622 flags, etc. can be set to avoid sending data to connection that
6623 is not valid anymore.
6625 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6626 the connection. After that it sets SILC_SET_DISCONNECTED.
6627 It is, however, possible that the socket data is not still freed.
6628 The silc_server_packet_process now checks that data is not
6629 read or written to connection that is DISCONNECTED. The socket
6630 get's freed when the reference counter hits zero.
6632 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Changed the client operation API: channel_message operation's
6635 `sender' is now the client entry of the sender, not the nickname
6636 and the `channel' is the channel entry, not the channel name.
6638 In the private_message operation the `sender' is now also the
6639 client entry of the sender not the nickname.
6641 Affected file is lib/silcclient/ops.h and all applications
6642 using the client operations.
6644 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Moved the calling of ops->connect() from connect_to_server_final
6647 into receive_new_id functin since that is the point when the
6648 client is actually allowed to send traffic to network. The
6649 affected file is lib/silcclient/client.c.
6651 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6654 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6655 (if needs broadcasting) instead of broadcasting the packets one
6656 by one which would make a burst in the network traffic.
6658 * Added `broadcast' argument to the functions in silcd/server.[ch]
6659 silc_server_create_new_channel[_with_id] to indicate whether
6660 to send New Channel packet to primary router.
6662 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Added new function into the silcd/server.[ch] files:
6665 silc_server_create_new_channel_with_id to create new channel with
6666 already existing Channel ID.
6668 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6669 lib/silccore/silcpacket.h. This packet is used t send list of
6670 Set Mode payloads inside one packet. Server uses this to set
6671 the modes for the channels and clients on those channels, that it
6672 announced to the router when it connected to it. The protocol
6673 specification has been updated accordingly.
6675 * The silc_server_new_channel did not handle the packet coming
6676 from normal server as it normally does not send that. However,
6677 when it announces its channels it does send it. Implemented
6678 the support for that.
6680 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6681 into the file lib/silccore/id.h.
6683 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Fixed memory leaks in the functions silc_idlist_del_client,
6686 silc_idlist_del_channel and silc_idlist_del_server in the file
6687 silcd/idlist.c. All of those leaked like a sieve.
6689 * Fixed some small memory leaks in the client's function
6690 silc_client_notify_by_server.
6692 * Added functions into silcd/server.c: silc_server_announce_clients,
6693 silc_server_announce_channels and silc_server_announce_server.
6694 These functions are used by normal and router server to announce
6695 to its primary router about clients, channels and servers (when
6696 router) that we own. This is done after we've connected to the
6699 These functions effectively implements the following packet types:
6700 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6701 and SILC_PACKET_NEW_ID_LIST.
6703 * Added new functions into the silcd/packet_receive.[ch]:
6704 silc_server_new_id_list, silc_server_new_channel_list and
6705 silc_server_new_channel_user_list to handle the incoming
6706 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6708 * Added support of changing Channel ID in the function
6709 silc_server_replace_id. If the server that announces a channel
6710 to the router already exists in the router (with same name but
6711 with different Channel ID), router is responsible to send
6712 Replace ID packet to the server and force the server to change
6713 the Channel ID to the one router has.
6715 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6716 client that the Channel ID has been changed by the router. The
6717 normal server sends this to the client. Client must start using
6718 the new Channel ID as the channel's ID.
6720 Implemented handling of this new type into lib/silcclient/client.c
6721 into the function silc_client_notify_by_server.
6723 * Added new function silc_idlist_replace_channel_id into the files
6724 silcd/idlist.[ch] to replace the Channel ID.
6726 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Call silc_server_command_identify_check always when processing
6729 the IDENTIFY command in silcd/command.c
6731 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6733 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6734 send keepalive packets. The packet can be sent by clients,
6735 servers and routers.
6737 Added function silc_socket_set_heartbeat into the file
6738 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6739 If not set, the heartbeat is not performed. The actual
6740 heartbeat is implemented in the low level socket connection
6741 library. However, application is responsible of actually
6744 Added silc_server_send_heartbeat to send the actual heartbeat
6745 packet into silcd/packet_send.[ch]. Server now performs
6746 keepalive with all connections.
6748 * Added silc_task_get_first function into lib/silcutil/silctask.c
6749 to return the timeout task with shortest timeout. There was a bug
6750 in task unregistration that caused problems. TODO has been
6751 updated to include that task system must be rewritten.
6753 * The client library will now resolve the client information when
6754 receiving JOIN notify from server for client that we know but
6755 have incomplete information.
6757 * Rewrote parts of silc_server_remove_from_channels and
6758 silc_server_remove_from_one_channel as they did not remove the
6759 channel in some circumstances even though they should've.
6761 * Encryption problem encountered in server:
6763 The LEAVE command used to send the Channel Key packet to the
6764 router immediately after generating it. However, the code
6765 had earlier sent Remove Channel user packet but not immediately,
6766 ie. it was put to queue. The order of packets in the router
6767 was that Channel Key packet was first and Remove Channel User
6768 packet was second, even though they were encrypted in the
6769 reverse order. For this reason, MAC check failed. Now, this
6770 is fixed by not sending the Channel Key packet immediately but
6771 putting it to queue. However, this is more fundamental problem:
6772 packets that are in queue should actually not be encrypted
6773 because packets that are sent immediately gets encrypted
6774 actually with wrong IV (and thus MAC check fails). So, packets
6775 that are in queue should be encrypted when they are sent to
6776 the wire and not when they put to the queue.
6778 However, the problem is that the current system has not been
6779 designed to work that way. Instead, the packet is encrypted
6780 as soon as possible and left to the queue. The queue is then
6781 just purged into wire. There won't be any fixes for this
6782 any time soon. So, the current semantic for packet sending
6785 o If you send packet to remote host and do not force the send
6786 (the packet will be in queue) then all subsequent packets to the
6787 same remote host must also be put to the queue. Only after the
6788 queue has been purged is it safe again to force the packet
6791 o If you send all packets immediately then it safe to send
6792 any of subsequent packets through the queue, however, after
6793 the first packet is put to queue then any subsequent packets
6794 must also be put to the queue.
6796 Follow these rules and everything works fine.
6798 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Added new function silc_server_remove_clients_by_server to
6801 remove all client entries from ID list when the server connection
6802 is lost. In this case it is also important to invalidate all
6803 client entires as they hold the invalid server entry. This
6804 fixes fatal bug when server has lost connection and will reconnect
6807 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Made some sanity checks to silc_server_daemonise like to check
6810 whether the requested user and group actually exists.
6812 * Added sanity check to SKE's silc_ske_responder_finish to check
6813 that the public and private key actually is valid.
6815 * Invalidate the client's nickname when receiving Replace ID
6816 packet and the Client ID is being replaced. This means that the
6817 server will query the nickname if someone needs it (client)
6820 * Sort the ID Cache in client library when the ID Cache data
6821 has changed (needs sorting).
6823 * Do not allow for SILC client to create several connections to
6824 several servers. The client does not support windows right now
6825 and generating multiple connections causes weird behaviour.
6827 Irssi-silc client does support windows and can handle several
6828 connections without problems, see: www.irssi.org and SILC plugin.
6830 * Fixed some places where client was added to the IDList. The
6831 rule of thumb is following (in order to get everything right):
6832 If the client is directly connected local client then the
6833 `connection' argument must be set and `router' argument must be
6834 NULL to silc_idlist_add_client function. If the client is not
6835 directly connected client then the `router' argument must
6836 bet set and the `connection' argument must be NULL to the
6837 silc_idlist_add_client function.
6839 * The funtion silc_server_packet_send_local_channel actually did
6840 not check whether the client was locally connected or not. It
6841 does that now. Fixed a bug related to LEAVE command.
6843 * Fixed Remove Channel User payload parsing bug in server's
6844 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6846 * The server's silc_server_save_channel_key now checks also the
6847 global ID list for the channel as it might not be in the local
6848 list. Fixed a bug related to LEAVE command.
6850 * Is this the end of the [<unknown>] buglet that has been lurking
6851 around for a long time? A little for loop fix in server's
6852 silc_server_command_whois_parse that is used by both IDENTIFY
6853 and WHOIS command. At least, this was a clear bug and a cause
6854 of one type of [<unknown>] buglet.
6856 * WHOIS and IDENTIFY commands call the function
6857 silc_server_command_[whois/identify]_check function even if
6858 we are not router server.
6860 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Added --with-gmp configuration option. If set the GMP
6863 is always compiled in the SILC source tree. If not set then
6864 it is checked whether the system has the GMP3 installed. If
6865 it has then the GMP won't be compiled (the system's headers
6866 and library is used), if it doesn't have it then the GMP is
6867 compiled in the SILC source tree.
6869 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Changed RSA private exponent generation to what PKCS #1
6872 suggests. We try to find the smallest possible d by doing
6873 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6874 not security fix but optimization.
6876 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6878 * Added new config entry [Identity] to fork the server and run
6879 it as specific user and group. A patch from Bostik.
6881 * Imported Dotconf configuration library into lib/dotconf.
6882 This will be used to create the SILC configuration files later.
6883 It will appear in the distsribution after this commit.
6885 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6887 * A big code auditing weekend happening. Auditing code for
6888 obvious mistakes, bugs and errors. Also, removing any code
6891 Removed files for being obsolete:
6893 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6894 inline in the file lib/silcutil/silcbuffer.h)
6896 o lib/silcutil/silcbufutil.c (the header has inline versions)
6898 Changed code to fix possible error conditions:
6900 o The buffer formatting routines now check that the destination
6901 buffer really has enough space to add the data. This applies for
6902 both buffer formatting and unformatting
6903 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6904 unformatting was changed to accomodate following rules:
6905 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6906 sent to the function while XXX_*STRING will not allocate or copy
6907 the data into the buffer. Instead it sets the pointer from the
6908 buffer into the pointer sent as argument (XXX_*STRING used to
6909 require that the pointer must be allocated already). This change
6910 makes this whole thing a bit more consistent and more optimized
6911 (note that the data returned in the unformatting with XXX_*STRING
6912 must not be freed now). The routines return now -1 on error.
6914 o Tried to find all code that use buffer_format and buffer_unformat
6915 and added return value checking to prevent formatting and
6916 especially unformatting errors and possible subsequent fatal
6919 o Changed ske->x and ske->KEY to mallocated pointers in
6920 lib/silcske/silcske.h. Fixed possible data and memory leak.
6922 o Added return value checking to all *_parse* functions. Fixed
6923 many memory leaks as well.
6925 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6926 so that buffer overflows would not happen. All code now also
6927 checks the return value as it can fail.
6929 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Added reconnection support to server if the normal server looses
6932 its connection to the router (for example if router is rebooted).
6933 The server performs normal reconnection strategy implemented
6934 to the server. Affected file silcd/server.c.
6936 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6938 * Added new packet type SILC_PACKET_SET_MODE that is used to
6939 distribute the information about changed modes (for clients,
6940 channels and clients channel modes) to all routers in the
6941 network. Updated the protocol specification accordingly.
6943 Added functions into silcd/packet_send.c and
6944 silcd/packet_receive.c: silc_server_send_set_mode,
6945 silc_server_set_mode.
6947 Added new files silcmode.[ch] into lib/silccore that implements
6948 the encoding and decoding of Set Mode Payload. Added new type
6949 SilcSetModePayload. Moved the definitions of different modes
6950 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6952 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Oops, a little mistake in server's connection authentication
6955 protocol. The protocol is not ended with FAILURE but with
6956 SUCCESS if the authentication is Ok. :) Affected file is
6959 * Implemented NICK_CHANGE notify handling in server in the file
6960 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6961 the local clients on the channel. After the changing nickname
6962 in router environment snhould work and the [<unknown>] nickname
6963 should appear no more.
6965 The silc_server_replace_id function that receives the Replace ID
6966 payload now sends the NICK_CHANGE notify type also in the file
6967 silcd/packet_receive.c
6969 * Changed WHOIS and IDENTIFY command to support the maximum amount
6970 of arguments defined in protocol specs (3328 arguments). This
6971 fixed a bug that caused problems when there were more than three
6974 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Added extra parameter, command identifier, to the
6977 silc_client_send_command so that explicit command identifier
6980 Changed that ID list routines uses specific command identifier
6981 when sending WHOIS/IDENTIFY requests to the server so that they
6982 can be identified when the reply comes back.
6984 Affected files lib/silcclient/command.[ch],
6985 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6987 * Added `sender' argument to silc_server_packet_send_to_channel
6988 to indicaet the sender who originally sent the packet to us
6989 that we are now re-sending. Ignored if NULL. Affected file
6990 silcd/packet_send.[ch].
6992 * Added some server statistics support in silcd/server_internal.h
6993 SilcServerStatistics structure and around the server code. Also
6994 send some nice statistics information when client is connecting
6997 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Fixed channel ID decoding in server's JOIN command reply in
7000 silcd/command_reply.c
7002 * Fixed braodcasting of replace ID payload to not to send it if
7003 we are standalone server in silcd/packet_receive.c.
7005 * Fixed all channel message sending routines to not to send
7006 packets to clients that has router set, since they are routed
7007 separately in the same function earlier. Affects file
7008 silcd/packet_send.c and all channel packet sending functions.
7010 * In USERS reply, res_argv[i] are not allocated, the table
7011 is allocated. Thus changed that free the table, not its
7014 * In server's whois_check and identify_check if the client is
7015 locally connected do not send any WHOIS commands - they are not
7018 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Fixed some minor bugs in client when sending WHOIS command. The
7021 arguments was in wrong order.
7023 * Removed statis function add_to_channel from server in
7024 silcd/command.c that was previously used with the joining but
7027 * Tested USERS command in router environment successfully with two
7028 routers, two servers and two clients.
7030 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7032 * Reorganized the USERS command and command reply in client library
7033 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7034 When the command is given by user we register a pending command
7035 callback that will reprocess the command after the reply has been
7036 received from the server. When reprocessing the packet we then
7037 display the information. Thus, the USERS information is displayed
7038 now in the command callback instead of in the command reply
7039 callback. The processing of the command is same as previously
7040 when server has sent the command reply in the JOINing process.
7042 * Added to USERS command in silcd/command_reply.c to join the client,
7043 we didn't use to know about, to the channel after we've created
7044 a client entry for it. Also, for clienet we did know already still
7045 check whether it is on the channel or not and add it if not.
7047 * Removed silc_server_command_join_notify as the function and its
7050 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Changed the client's pending command handling to the same as the
7053 server's pending command handling. It is also now possible to
7054 execute command reply functions from other command reply
7055 function as the function callbacks for commands and command
7056 replies are one and same. The pending commands are not static
7057 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7058 in client connection context. Thus, pending commands are server
7059 connection specific as it is convenient.
7061 Changed the function silc_client_command_pending and
7062 silc_client_command_pending_del and added new function
7063 silc_client_command_pending_check. Removed the
7064 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7067 * Added cmd_ident, current command identifier, to the client
7068 connection context in lib/silcclient/client.h to keep track on
7069 command identifiers used in command sending. Client's command reply
7070 function handling now supports the mandatory command identifiers.
7072 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7073 funtions in client to fully support pending command callbacks.
7075 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7076 as one of the arguments to the application in the command reply
7079 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7080 before first releasing SILC but came back. Now it is removed again
7081 and should come back nomore. The FORWARDED flag was used only
7082 by the JOINing procedure by forwarding the command packet to router.
7083 Now, the JOINing procedure has been changed to more generic (due
7084 to various router environment issues) and FORWARDED is not needed
7085 anymore for anything. The protocol specification is yet to be
7088 Now, removed silc_server_packet_forward from server and the flag
7089 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7091 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Renamed NAMES command to USERS command. The NAMES was named that
7094 due to historical reasons. Now it is renamed. Also, rewrote
7095 parts of the USERS command. The nickname list is not sent anymore
7096 by the server. Only Client ID and mode lists are sent in the USERS
7097 command. Changed this also to the protocol specification.
7099 The client now resolves the names and stuff after it receives
7100 the USERS list from the server when joining to the channel.
7102 * WHOIS and IDENTIFY commands has been changed to support multiple
7103 Client ID's per command. One can now search for multiple users
7104 in the network by sending only one WHOIS or IDENTIFY command.
7105 Changed the code and the protocol specifications.
7107 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7108 uses silc_server_command_whois_parse to parse the request. */
7110 * If normal server, do not parse the WHOIS and IDENTIFY requests
7111 before sending it to the router. Saves some time.
7113 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Fixed JOIN command on client library. Wrong number of arguments
7116 used to crash the client.
7118 * Added silc_server_channel_has_global function to check whether
7119 channel has global users or not.
7121 * Added silc_server_channel_has_local function to check whether channel
7122 has locally connected clients on the channel.
7124 * The silc_server_remove_from_one_channel now checks whether the
7125 channel has global users or not after given client was removed from
7126 the channel. It also checks whether the channel has local clients
7127 on the channel anymore. If it does not have then the channel entry
7128 is removed as it is not needed anymore.
7130 * The silc_server_notify now checks on JOIN notify whether the joining
7131 client is one of locally connected or global. If it is global then
7132 the channel has now global users on the channel and that is marked
7133 to the channel entry. Also, it now saves the global client to
7134 global list who is joining and JOINs it to the channel. This is
7135 for normal server, that is.
7137 Changed silc_server_send_notify_on_channel,
7138 silc_server_packet_relay_to_channel and
7139 silc_server_packet_send_to_channel check if we are normal server
7140 and client has router set (ie. global client) do not send the
7141 message to that client, as it is already routed to our router.
7143 * Implemented LEAVE notify type handling in silc_server_notify
7146 * Tested LEAVE command in router environment successfully. Tested
7147 with two routers, two servers and two clients.
7151 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7153 * Implemented SIGNOFF notify type handling in silc_server_notify
7156 * silc_server_remove_id now removes the client entry from all channels
7157 it has joined and thusly sends SIGNOFF notify type.
7159 * Rewrote the NAMES list generation in server by removing two excess
7160 loops. The lists are created now inside one loop.
7162 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7164 * silc_server_remove_channel_user checks now also global list
7165 for channel and client.
7167 * silc_server_new_channel_user checks now both local and global
7168 list for channel and client. Fixed a bug in client id decoding.
7169 Used to decode wrong buffer.
7171 * silc_server_channel_message checks now both local and global
7172 list for channel entry.
7174 * Tested channel joining (hence JOIN) in router environment
7175 successfully. Tested with two routers, two servers and two
7178 * Tested channel message sending in router environment successfully.
7180 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7182 * Added silc_server_save_channel_key into server.[ch] to save the
7183 received channel key in Channel Key payload processing. It is
7184 also used in JOIN command reply handling.
7186 Equivalent function silc_client_save_channel_key added into
7187 client.[ch] into client library.
7189 * Changed JOIN command reply to send information whether the channel
7190 was created or not (is existing already) and the channel key
7191 payload. Changed protocol specs accordingly.
7193 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7194 the request was sent by ID and not by nickname. Crashed on
7197 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7200 now correctly save the received data.
7202 * silc_server_free_sock_user_data now notifies routers in the
7203 network about entities leaving the network.
7205 At the same time implemented functions silc_server_remove_id
7206 and silc_server_send_remove_id to receive and send REMOVE_ID
7207 packets. The packet is used to notify routers in the network
7208 about leaving entities. The ID removed will become invalid in
7211 * Added function silc_idlist_del_server into server. Removes and
7212 free's server entry from ID list.
7214 * silc_server_private_message function now checks, if we are router,
7215 that the destination ID really is valid ID, naturally.
7217 * In router when NEW_ID packet is received (for new client) the
7218 hash of the Client ID is saved in the ID Cache but the
7219 client->nickname is set to NULL, instead of putting the hash
7222 IDENTIFY command now also checks that client->nickname must be
7223 valid. If it is not if will request the data from the server who
7224 owns the client. Added new function
7225 silc_server_command_identify_check.
7227 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7228 to set the command to already allocated Command Payload.
7230 * Tested private message sending in router environment with two
7231 routers, two servers and two clients. Fixed minor bugs and now
7234 * Fixed segfault from client's NAMES command. Used to crash if
7237 * Forwarded packets must not be routed even if it is not destined
7238 to the receiver. Changed server code comply with this.
7240 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Added `require_reverse_mapping' boolean value to ServerParams
7243 structure. If TRUE (not default) the server will require that
7244 the connecting host has fully qualified domain name.
7246 If the reverse mapping is not required and hostname could not be
7247 found the IP address is used as hostname.
7249 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Implemented version string checking to both client and server.
7252 The check is incomplete currently due to the abnormal version
7253 strings used in development version of SILC.
7255 * Changed all command functions in server to use the new
7258 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7260 * Changed char *data to unsigned char *data in ID Cache system to
7261 support binary data as ID Cache data. Changed code to support
7262 binary data in lib/silccore/idcache.c.
7264 * Renamed silc_server_packet_relay_command_reply to
7265 silc_server_command_reply as it is normal packet receiving
7266 function. Rewrote the function to accept command replys for
7267 servers and not only for clients.
7269 * Mark remote router always as registered server if we are connecting
7270 to it. Otherwise, commands sent by the router to us are ignored.
7272 * All ID List find routines now returns the ID Cache Entry pointer
7273 as well if requested.
7275 * WHOIS command works now in router environment, tested with two
7276 routers, two servers and two clients.
7278 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7279 in router environment (as it is almost equivalent to WHOIS) but
7280 hasn't been tested thoroughly. Added new functions:
7282 silc_server_command_identify_parse
7283 silc_server_command_identify_send_reply
7284 silc_server_command_identify_from_client
7285 silc_server_command_identify_from_server
7287 * Disabled route cache adding because adding two different ID's with
7288 same IP replaces the old cache entry thus giving wrong route.
7289 The entry->router->connection is always the fastest route anyway
7290 so route cache may not be needed. Of course, new routes maybe
7291 established after receiving the ID when the entry->router->connection
7292 might not be anymore the most optimal.
7294 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7296 * Add route cache for received ID for fast routing.
7298 * Added silc_server_packet_route to route received packet on router
7299 that is not destined to us.
7301 * Renamed silc_server_get_route to silc_server_route_get.
7303 * Added id_string and id_string_len fields into SilcServer to
7304 include encoded ServerID for fast comparing without excess
7305 encoding of the ID's.
7307 * Cleaned up WHOIS command on server side. Added following static
7310 silc_server_command_whois_parse
7311 silc_server_command_whois_check
7312 silc_server_command_whois_send_reply
7313 silc_server_command_whois_from_client
7314 silc_server_command_whois_from_server
7316 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7317 arguments in command replies. All command functions should be
7318 updated to use this macro.
7320 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7322 * Minor typo fixes on command reply handling on server.
7324 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added silc_server_command_add_to_channel internal routine to add
7327 the client to the channel after router has created the channel and
7328 sent command reply to the server.
7330 * Added generic silc_server_send_command to send any command from
7333 * Use static buffer with ID rendering instead of duplicating data.
7335 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7337 * Fixed a channel user mode bug when joining to a channel server gave
7338 everybody channel founder rights, oops.
7340 * We mark ourselves as the router of the incoming server connection
7341 if we are router ourselves. This way we can check in some packet
7342 sending functions whether it is locally connected server. For
7343 incoming router connections we put NULL.
7345 * For router sending packets locally means now always sending the
7346 packet cell wide; to local clients and local servers. For normal
7347 server sending packet locally means sending it to only local
7350 * Fixed the JOIN command to really work in router environment. If the
7351 channel is created it is always created by the router. Router is
7352 also responsible of making the initial joining to the channel,
7353 sending JOIN notify to the sending server and distributing
7354 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7355 does not exist server doesn't do anything else but forward the
7356 command to the router which performs everything.
7358 * Added silc_server_send_channel_key function to send the Channel Key
7361 * Added silc_server_create_channel_key to create new channel key. The
7362 channel key is now re-generated everytime someone joins or leaves
7363 a channel, as protocol dictates. Note: channel->key_len is the
7366 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7368 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7369 packet_receive.[ch] to separate packet sending and receiving
7370 routines. The server.[ch] now includes everything else including
7371 actual packet processing (writing and reading data) and other
7374 Renamed silc_server_private_message_send_internal to
7375 silc_server_send_private_message. The routine is still though
7376 used only to relay private messages as server does not send
7377 private messages itself.
7379 Renamed silc_server_new_channel to silc_server_create_new_channel
7380 and added new function sicl_server_new_channel that handles the
7381 incoming New Channel packet. Added also new sending function
7382 silc_server_send_new_channel to send New Channel Payload.
7384 * Added new function silc_server_notify to process incoming notify
7385 packet to the server/router. Server may then relay the notify
7386 to clients if needed.
7388 * Added new function silc_server_new_channel_user to process incoming
7389 New Channel User packet. Router will redistribute the packet and
7390 send JOIN notify to its local clients and locally connected servers
7391 if needed. Normal server will send JOIN notify to its local client
7392 on same channel when received this packet. Added also corresponding
7393 sending function silc_server_send_new_channel_user to sent the
7396 * Added boolean route argument to send_notif_to_channel and
7397 packet_send_to_channel functions to attempt to route the packet
7398 if it is TRUE and send only locally if it is FALSE.
7400 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * silc_server_replace_id now broadcasts the received replace ID
7403 packet if it is not broadcast packet already. The router must
7404 broadcast to inform other routers about changed ID.
7406 * Added backpointer to server's router into SilcServer context in
7407 silcd/server_internal.h.
7409 * Fixed silc_server_packet_broadcast to send correct broadcast
7412 * The channel key is now distributed to the local client as soon
7413 as it is received from the router (in router environment) so that
7414 no other packet may be sent for the channel until client has
7417 * silc_server_remove_channel_user now broadcasts the received
7418 Remove Channel User packet if it is not broadcast packet already.
7419 The router must broadcast to inform other routers about removed
7422 * Added users field into SilcPacketContext that is a reference count
7423 of the context. One can increase the reference count by calling
7424 silc_packet_context_dup which is now changed to just increase the
7425 reference count instead of duplicating the data. The reference
7426 count is decresed by calling silc_packet_context_free that will
7427 free the data after the reference count hits zero.
7429 For now on the packet context and everything allocated into it
7430 (including the raw packet from network) must be freed by calling
7431 the new silc_packet_context_free function. Added also new function
7432 silc_packet_context_alloc that must be used now to allocate the
7433 context. This also means that if a routine is asynchronous from
7434 silc_[client/server]_packet_parse_type the packet context must
7435 be duplicated by calling silc_packet_context_dup. Otherwise it
7436 gets free'd after silc_[client/server]_packet_parse_type returns.
7437 Also, one must remember that if packet is duplicated then its
7438 reference count must be decresed by calling the free function as
7439 many times as it was duplicated.
7441 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7442 from both client and server.
7444 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7446 * Made joining to a channel working in router environment.
7448 * Cleaned up JOIN command on server side and create function
7449 silc_server_command_join_channel internal routine to make the
7452 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Changed silc_command_pending list to SilcDList. Also, added
7455 `ident' field to SilcServerCommandPending structure to identify
7456 the reply and to call correct callback.
7458 Added silc_server_command_pending_check function to replace the
7459 corresnponding macro. The silc_command_pending list is not
7462 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7463 to set identifier to previously allocated Command Payload. It
7464 is used to set identifier for command when resending Command
7467 * Added silc_command_payload_encode_payload to encode Command
7468 Payload buffer from SilcCommandPayload structure.
7470 * Added silc_argument_payload_encode_payload to encode Argument
7471 payload buffer from SilcArgumentPayload structure.
7473 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7475 * Changed WHOIS command to support router connection on server side.
7476 The whois request is always sent to router unless the server is
7477 standalone server. After server has received the reply from the
7478 router will it send the reply to the client.
7480 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7481 broadcast received broadcast packet. The function is used only
7482 by router. The broadcast packet is always sent to the router's
7485 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7486 render given ID to printable string, for log files for example.
7488 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Made basic router to router connections working. At least they
7491 can now connect to each other but nothing really works the way
7492 they are supposed - yet.
7494 * Added new initiator token to RouterConnection configuration
7495 file in silcd/serverconfig.[ch]. It is used to tell whether we
7496 are the initiator to the remote router or whether we'll expect
7497 the other end to connect.
7499 * Moved registering of listener task to silc_server_init, hence
7500 the server starts listenning as soon as it is run, even if it
7501 does not have connections to other routers. Let's see how well
7504 * Changed default connection retry timeouts for more suitable in
7507 * Removed cipher and such arguments from silc_idlist_add_client
7508 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7509 Added new function silc_idlist_add_data to add the keys and stuff
7512 * Added SilcIDListData structure and added it to SilcClientEntry
7513 and SilcServerEntry as their first field in the structure. This
7514 way we can explicitly cast the ID entries to the SilcIDListData
7515 structure and get common data for the entries. In past, we had
7516 to first check what type of connection it is and then cast it to
7517 correct ID entry type. Now, we can directly cast the opaque
7518 pointer to the SilcIDListData (no matter what ID entry it actually
7519 is) and get the data needed.
7521 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7523 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7524 in some circumstances even if threre were timeout tasks, though not
7525 IO tasks, but tasks anyway. Now fixed.
7527 * Defined SilcServerConnection structure to hold connection specific
7528 stuff about directly connected servers and routers. The definition
7529 is currently in silcd/server_internal.h. I thought about having
7530 a bit more important role fro this struct but for now it is used
7531 only when connecting to other server (or router actually).
7533 * Added connecting retry support in server when connecting to
7534 router(s). The retry feature implement exponential backoff
7535 algorithm. Also, added SilcServerParams structure to hold default
7536 parameters for server. For now, it include these retry settings
7537 and are hard coded. After server is moded to be as Silc Server
7538 Library this structure will be more important.
7540 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7542 * Changed client librarys channel->clients table to SilcList and
7543 changed code accordingly.
7545 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Changed client's channel table to SilcList and changed code
7548 accordingly. Also changed SilcChannelClientEntry to include back-
7549 pointer to the channel so that client entry can use that structure
7550 as list as well and we have fast cross-reference to the channel.
7551 This change dramatically decreased the complexity of channel
7552 handling with client entry and vice versa (removed one extra
7553 loop when searching for channel entry from many functions).
7555 * Changed server->sim from table to SilcDList and changed code
7558 * NAMES command can now be used from user interface. It will show
7559 the user list on the channel, neatly.
7561 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7562 Code now saves realname of the user if it becomes available.
7564 * Renamed configure.in to configure.in.pre and made ./prepare
7565 script to automatically add correct version string to
7566 configure.in which it creates from configure.in.pre.
7568 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * NAMES command reply now shows users mode with the nickname when
7573 * Moved silc_client_ch[u]mode[_char] functions from
7574 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7575 place sucks, they are utility functions and should be in some
7578 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7580 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7583 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Added TRQ (efficient deque and list library) into lib/trq. This is
7588 a very good list library that is currently used in the SILC. Defined
7589 SilcList API over the library because I didn't like the API very
7590 much. See lib/trq/silclist.h for the API and examples of how to
7591 use the API. Fixed various places in the code to use the new
7592 SilcList API. The SilcList is meant for lists that has a structure
7593 already defined as a list. It is not suitable to add just some
7594 context to the list (in TRQ, the context is the list actually).
7596 So, I defined SilcDList that can be used for the purpose where
7597 predefined list structure does not exit. This can be used as
7598 such list. Now some context just can be added to the SilcDList.
7599 Currently this list is not used in the SILC just yet, though there
7600 are a lot places where this can replace dynamically allocated
7601 tables and I will fix these places, later, to use SilcDList.
7602 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7603 and use TRQ internally).
7605 Also fixed some annoying warning messages that the original TRQ
7606 code generated. Also minor changes to TRQ's Makefile.in.
7608 * Added support for querying by Client ID to both WHOIS and
7609 IDENTIFY commands into server, as required by the protocol.
7611 * Removed method function pointers from SilcBuffer structure. They
7612 weren't used to anything and just increased the context size for
7613 no good reason. This change also made silc_buffer_alloc and
7614 silc_buffer_free functions inline functions.
7616 * Disabled command flooding detection support until it's fixed so
7617 that it accepts commands in but does not execute them more than once
7620 * Added silc_net_localhost(), to return local hostname, into
7621 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7622 that must be initialized before calling silc_client_init.
7624 * Added new function: silc_server_send_notify_on_channels to send
7625 notify messages to all channels client has joined. It is assured
7626 that the message is sent only once per client.
7628 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7629 lib/silcutil/silcutil.[ch] as silc_format function. The new
7630 function is generic and is used by server as well, not only by
7631 the logging routines.
7633 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7634 the provided version string was not acceptable. Added new function:
7635 silc_ske_check_version into lib/silcske/silcske.h. The function
7636 must be implemented by the application (client or server) and it
7637 does not reside in the SKE library. The function checks the version
7638 string remote end sent.
7640 * Added back pointers (to opaque context and to SilcSocketConnection)
7641 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7643 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7644 duplicate packet context structure.
7646 * Changed `notify' client operation to send same arguments as client
7647 receives from server except for ID's. ID's are mapped to correct
7648 ID entry and that is returned. Also, if channel entry is not sent
7649 by server but the notify is for channel the channel entry is sent
7650 to application (otherwise application doesn't know that it is for
7651 channel (library gets it from packet's Destination ID)).
7653 * Added silc_client_remove_from_channels into client library to
7654 remove a client from all channels it has joined to. Used when
7655 received SIGNOFF notify from server. Added also new function
7656 silc_client_replace_from_channels to replace old ID entry with
7657 new ID entry on all channels. Used when received NICK_CHANGE
7660 * Fixed ID Cache list handling in silc_idlist_get_client in
7661 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7662 to get (or query) client by ID.
7664 * Updated TODO list.
7666 * Added connection authentication status message defined by the
7667 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7668 support for these into the code in client and server side.
7670 * Added generic function silc_client_send_command to send any command
7671 with variable argument list. Application should use this function
7672 to send commands if the command functions provided by the library
7673 does not suite for the application's user interface needs.
7675 * Added new `failure' client operation. Application is notified about
7676 received failure packet if client is executing a protocol. In this
7677 case the protocol's execution has failed.
7679 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7680 is required by the protocol.
7682 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7683 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7686 * Added status flag to SilcSKE object to indicate realtime status
7687 of the SKE protocol.
7689 * Application receives now exactly same command reply arguments as
7690 the library receives from server. However, if ID is received the
7691 corresponding ID entry is returned to the application (eg. Client
7692 ID is mapped to correct SilcClientEntry entry and that is returned).
7693 Changed command_reply client operation due to this change.
7695 * Changed all ID's in commands and in command replys as ID Payloads.
7696 Change affected both client and server side codes.
7698 All ID's sent in SILC network (with execption of ID's in SILC
7699 Packet header) are sent in ID Payload to support variable length
7702 * Server now notifies nick changes and notifies all clients on
7703 the channels about the new nickname (about the new Client ID,
7706 * Implemented CMODE command to change channel modes. Supports all
7707 channel modes defined by the protocol specs except ban and invite
7708 lists. (Also, private channel key mode is supported but support for
7709 setting private channel key in client is missing, thus, this mode
7710 has no effect on client side (except that server requires that the
7711 client uses private channel key and normal channel traffic does not
7714 Also, invite mode works per se, but INVITE command does not work
7715 yet correctly, so you can set channel as invite only channel but
7716 inviting clients to the channel does not work (it is yet to be
7717 thought what's the best way to do it).
7719 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7720 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7721 Implemented CUMODE command to change user's mode on the channel.
7722 Supports all modes defined by the protocol specs.
7724 * Added NAMES command reply to return users modes on the channel.
7726 * Removed unnecessary and slow ciphers from lib/silccrypt.
7728 * Set SO_KEEPALIVE option to connection sockets by default.
7730 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7732 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7733 redefined the Notify Payload into protocol specs.
7735 * Added silc_id_payload_parse_id to get ID directly from raw
7738 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7741 accept searching by Client ID as well.
7743 * Added support for LEAVE and SIGNOFF notify types in client library.
7745 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7746 to parse ID Payload from raw data.
7748 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Added flags parameter into silc_ske_assemble_security_properties
7751 function in lib/silcske/silcske.[ch].
7753 * Changed notify client operation to fit better for notify messages
7754 sent by server. The notify payload received from server is now
7755 passed to the application (after parsing it to SilcNotifyPayload).
7756 It is application's responsibility to retrieve the arguments
7757 from the payload and show the message the way it wants. The message
7758 sent by server is implementation specific.
7760 * Changed public keys to comply with the protocol specification.
7761 Old public keys are not supported anymore and are not compatible.
7763 * Removed nickname from Channel Payload as the latest draft removed
7764 it. The client must resolve the nickname from the NAMES command
7765 reply received when it joined the channel.
7767 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7769 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Fixed some errors in protocol specification drafts.
7773 * Created lib/silccore/silcnotify.c to implement Notify Payload
7774 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7775 generic payloads described by protocol specifications. The file
7776 includes implementations for ID Payload and Argument Payload.
7778 * Changed Command Payload implementation to use the new Argument
7779 Payload. Changed command_xxxx_payload to command_payload_xxxx
7780 to comply with SILC coding conventions.
7782 * Added suppport for Argument Payload handling in Notify Payload
7783 implementation as protocol requires it. Added the new support
7784 into server and client lib as well.
7786 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7788 * Added support for multiple nicknames on same channel. [n] is
7789 added locally to the nickname if there are more than one same
7790 nicknames on the channel.
7792 * Server now sends all nicknames that matched WHOIS request.
7793 Client also shows the list received from server.
7795 * Added TOPIC command to client side. User can now set and show
7796 current topic on channel.
7798 * Added MOTD command to client and server. Also, server sends the
7799 motd when client connects to the server.
7801 * Changed version strings to comply ISO 8601.
7803 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7805 * Fixed protocol error handling in client library. It should now
7806 cope even if the SKE fails for some reason.
7808 * Made new protocol specification drafts for submitting to IETF.
7810 * Implemented TOPIC command to server in silcd/command.c.
7812 * Added two new notify types into lib/silccore/silcnotify.h:
7813 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7814 notify nickname change and topic setting/change on a channel.
7816 * API change of command_reply operation in client library. The
7817 application gets now the status type received from server as well.
7819 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7821 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7823 * Cras fixed and optimized the packet handling even further and
7824 it should work now. Minor change to the prototype of function
7825 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7827 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7829 * Added new function into lib/silcutil/silcschedule.[ch]:
7830 silc_schedule_with_fd to select() a specified fd. The function
7831 returns after timeout expires or data arrives or goes. The
7832 function is used by packet routines to wait that all data is
7833 received from network.
7835 * Fixed data reading from network in lib/silccore/silcpacket.c.
7836 The code now assures that all data is read from the fd and then
7837 continues packet processing. This was a bug fix since the code
7838 used to drop some data in some circumstances.
7840 * Added new function into lib/silcclient/client.[ch]:
7841 silc_client_start_key_exchange to start key exchange after
7842 connection has been established to server. The code internally
7843 now uses this funtion but its main purpose was to provide it
7844 for applications that perform their own connecting. After
7845 application has created a connection it merely calls this
7846 function to start the key exchange between client and server.
7847 The library takes care of everything else after that.
7849 Updated also lib/silcclient/README to explain the usage of
7852 * Do not send to application information that connection has
7853 been established. Application gets notified it by connect
7856 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7858 * Applied cras's patch to add silc_schedule_one function. The
7859 function runs scheduler once and returns.
7861 * Fixed the scheduler after cras messed it up. The timeout
7862 handling works now as it's supposed to work.
7864 * Added into lib/silccore/ silcnotify.h to include notify
7865 message types support. Changed silc_server_send_notify*
7866 functions, in server.[ch], to support those new notify types.
7867 Added the support for the notify types into client library,
7868 as well. Added new notify client operation into ops.h in
7871 * Changed silc_server_packet_send_to_channel to send normal
7872 packets instead of just channel message packets. The function
7873 is now used to send the notify packets to channels. It is not
7874 used to send channel message packets anymore, as server never
7877 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7878 va_arg()s as it seems to require it nowadays. I guess, if SILC
7879 is compiled with older va_arg() the new code should work anyway.
7881 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7883 * Splitted core library. Core library (lib/silccore) includes
7884 now only SILC protocol specific core (and common) components.
7885 Created new utility library (lib/silcutil) that includes more
7886 generic purpose stuff. The stuff for util library was taken
7887 from the old core library. This was minor and easy split.
7889 * Created SILC Client Library (lib/silcclient) that includes
7890 implementation of the SILC client without user interface. This
7891 was major move from silc/ directory. The code has been changed
7892 so that it is transparent towards the user interface. The
7893 silc/ directory includes now the same user interface as before
7894 and it uses the new client library. Read lib/silcclient/README.
7895 Basicly, the client library performs everything else related
7896 to SILC except user interface handling. Also, configuration
7897 files are considered to be part of user interface and library
7898 does not handle them.
7900 This change also changed a lot of structures, function naming etc.
7901 Most important change was that SilcClientWindow object was
7902 renamed to SilcClientConnection in the client library. Created
7903 also new file lib/silcclient/ops.h. Also added new files
7904 silc/local_command.[ch] and silc/client_ops.[ch].
7906 All these changes were made to make it easier for user interface
7907 designers to create what ever user interface for the SILC client
7910 It is also expected that the server will be moved to lib
7911 directory as well and SILC Server Library will be created;
7912 sometimes in the future.
7914 * Removed Local commands from lib/silccore/silccommand.h as
7915 they are application specific and new client library does not
7916 handle any of those anymore.
7918 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7919 old client implementation in silc/.
7921 * Added support for callback functions in SILC_LOG_* macros.
7922 Application can now set its own callbacks that will be called
7923 instead of using the default functions that will always print
7924 the debug messages to stderr (or stdout). Also, debugging can
7925 now be disabled by setting silc_debug to FALSE and re-enabled by
7926 setting it to TRUE. Note, that logging will still work even
7927 if debugging is disabled.
7929 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7930 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7931 silc_log_reset_debug_callbacks.
7933 * To enable debugging in silc client one must give now -d
7934 option on command line.
7936 * Changed silc_schedule_init to automatically allocate task queues
7937 if they are not allocated before calling it.
7939 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7941 * Added GMP 3.1 into math library.
7943 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7945 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7946 a channel in SILC network. The packet is used by servers and
7947 routers to notify other routers that user has left a channel.
7948 This little feature was missing until now. Added the feature
7949 to protocol specification as well.
7951 Added functions: silc_server_send_remove_channel_user and
7952 silc_server_remove_channel_user into server.[ch].
7954 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7955 lib/silccore/silcpacket.h. However, they are not implemented
7958 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7960 * Fixed joining to a channel and sending channel messages
7961 between server and router. The channel message sending should
7962 now work inside a cell.
7964 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7966 * Fixed the private message sending between server and router.
7967 The private message sending should now work inside a cell.
7969 * Added silc_server_replace_id into server.[ch] to replace
7970 existing ID in the SILC network.
7972 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7973 and silc_idlist_replace_server_id into idlist.[ch] in server.
7975 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Fixed the server to server connections. Server can again now
7978 connect to router. Router to router connections probably does
7981 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7983 * Added dynamic protocol registering support. Now protocols can
7984 registered and unregistered on the fly. Patch by cras.
7986 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7988 * Added lib/contrib directory to hold routines that some platforms
7989 don't have but are needed by SILC.
7991 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7992 into lin/contrib to provide getopt() and getopt_long() for
7993 those who don't have it.
7995 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7997 * Added AWAY command to client. When away message is set and
7998 client receives a private message packet the client automatically
7999 replies to the sender with the away message.
8001 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8002 bug seemed to be the cause of recent problems when compiling
8005 * Added version detection support to SKE protocol specification
8006 and added the new changes to the SKE implementation as well.
8007 There were other minor changes in the SKE protocol as well.
8009 Many changes in lib/silcske/silcske.[ch] and in
8010 lib/silcske/payload.[ch].
8012 * Added ^U functionality, clear input line. Patch from cras.
8014 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8016 * Mainly small bugfixes on core library. Fixed some debugging
8017 logging and buffer overflow in silclog.c.
8019 * Updated config.sub and config.guess on the distribution tree.
8021 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8023 * Added command lagging support in server. Client may execute
8024 commands now only once in two seconds.
8026 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Optimized packet reception. MAC computation and checking is now
8029 also more optimized. A lot previously duplicated code is now
8030 used as generic by both client and server.
8032 * Fixed key pair generation in clientutil.c
8034 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8036 * Added into lib/silccore/silcbufutil.[ch] new function;
8037 silc_buffer_realloc.
8039 * Moved generic packet sending/encryption functions to
8040 lib/silccore/silcpacket.[ch] from client and server. Some
8041 rewriting of the functions.
8043 * Moved all generic packet reception/decryption functions to
8044 lib/silccore/silcpacket.[ch] from client and server. The
8045 packet processing is now much cleaner in both client and server.
8046 These were major changes in both client and server.
8048 * Created many common functions in server to do packet sending.
8049 Previously code were duplicated a lot, this has been removed
8052 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8054 * Rewrote major parts of the ID cache system. Don't know
8055 whether it is better now or not but at least the API is more
8058 * Major rewrite on ID cache stuff on client because of the ID
8059 cache API changes. Added idlist.c to client.
8061 * Also major rewrite on ID cache stuff on server as well.
8062 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8063 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8064 in hand, instead they are all put into the ID cache system now.
8065 All server_idlist_* routines uses ID cache now instead of
8066 traversing its own lists (those lists does not exist anymore).
8067 SilcIDList though still exists. Also, SilcXXXEntry's are
8070 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8072 * Finally made the SKE implementation compliant to the protocol
8073 specification. All mp integers are now binary encoded as
8074 opposed being HEX encoded.
8076 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8079 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8080 functions: silc_[encode/decode]_pem. Also added function
8081 silc_encode_pem_file to PEM encode with newlines ('\n') for
8084 * SILC public keys are now encoded either PEM or binary. Same
8085 option is for private keys as well. By default private keys
8086 are binary encoded and public keys PEM encoded. Silly HEX
8087 encoding were removed.
8089 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8090 function to create fingerprints.
8092 * Fixed a bug in SHA1; does not change the original data anymore.
8094 * Partly implemented INFO command on client and server side.
8095 Fixed CLEAR command. Changes to SERVER command; show current
8096 server(s) when giving command without arguments. Added
8097 VERSION command to client.
8099 * Added check to server that unregistered connections cannot
8100 execute commands (unless it is specificly allowed).
8102 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8104 * Fixed screen refresh.
8106 * Fixed channel joining bug from client. On some circumstances
8107 client tried to join to a channel it had already joined.
8109 * Added public key verification process into client's protocol.c.
8110 The client now verifies the public key from user and saves
8111 it into ~./silc/serverkeys/ directory.
8113 Added into: clientutil.[ch]: silc_client_verify_server_key.
8115 * Changed SKE protocol's silc_ske_initiator_finish function
8116 to accept callback function that verifies the received public
8117 key. Removed old silc_ske_verify_public_key function.
8119 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8121 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8122 silc_pkcs_private_key[_data]_set.
8124 * Made the password and public authentication more cleaner in
8125 server's protocol.c.
8127 * Removed historic and obsolete protocol `channel_auth' from
8128 both client and server.
8130 * Removed wrong way of sending command status messages from
8131 server to client in server's command.c. The old way violated
8132 protocol specification.
8134 Changes to silccore/silccommand.[ch]: removed
8135 silc_command_encode_status_payload -> not needed anymore,
8136 changed silc_command_encode_payload_va to accept extra
8137 argument on variable argument list. The argument type must
8138 now be provided to the function. Also, added new function:
8139 silc_command_encode_reply_payload_va which is same as
8140 normal command_encode_payload_va except command status type
8141 is provided as extra argument.
8143 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8145 * Added ~./silc directory handling. The directory includes the
8146 public and private keys for the client.
8148 Added silc_client_check_silc_dir, silc_client_create_identifier
8149 and silc_client_load_keys.
8151 * Implemented SILC protocol compliant public key. Added public
8152 and private key saving to and loading from files.
8154 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8155 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8156 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8157 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8158 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8160 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8161 silc_pkcs_load_[public/private]_key.
8163 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8165 * Added silc_server_get_route (route.[ch]) to get connection
8166 data for the fastest route for given ID.
8168 * Implemented INVITE command on client and server. The command
8169 were re-defined in the SILC Protocol Specification and the
8170 implementation now complies with the specification.
8172 * Implemented PING command on client and server.
8174 * Implemented NAMES command on client and server. The server side
8175 supports currently only normal server not router server yet.
8176 Some changes to NAMES definition in SILC protocol specification.
8178 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8180 * Implemented LEAVE command on client and server.
8182 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8183 again. This change was made to the protocol as well. Server
8184 should not violate the protocol specification anymore.
8186 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8188 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8189 was tested. SOCKS4 was not but should work anyway.
