1 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
4 that it is used to send error notifys if error occurs during
5 some SILC packet processing, except commands. The error
6 types are same as for command reply types. Defined that
7 if private message is sent to unknown Client ID the error
8 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
9 Updated the protocol specs and code. Affected files are
10 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
11 lib/silcclient/client_notify.c, silcd/packet_receive.c,
12 and irssi/src/silc/core/client_ops.c. Renamed the
13 SilcCommandStatus to SilcStatus.
15 * Defined the use of extra WHOIS attributes in WHOIS command.
16 The <Requested Attributes> (defined in a separate document)
17 can be used to request additional information about user
18 not returned by standard WHOIS command. Defined that server
19 can send WHOIS command directly to client. Client provides
20 the requested attributes to the server. Updated the protocol
21 specs. Protocol TODO #4. Implementation is not done yet
24 * Renamed function silc_client_command_status_message to
25 silc_client_status_message. Affected files are
26 lib/silcclient/command_reply.[ch].

35 Sun Apr 14 19:49:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
37 * Fixed a bug in library where sending a bogus authentication
38 payload would lead to a crash. Affected file is
39 lib/silccore/silcauth.c.
41 Sat Apr 13 13:09:24 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
43 * Added detach_disabled and detach_timeout server config
44 options to the server. Affected files silcd/serverconfig.[ch],
45 silcd/command.c and silcd/packet_receive.c.
47 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
49 * Added resolve_cmd_ident field to the SilcClientEntry structure
50 too so that if the entry is for example being resolved so
51 another command may attach to the same pending command reply
52 without requiring to resolve the same entry again. Added
53 support for adding multiple pending commands for one
54 command idenfier. Affected files lib/silcclient/command.[ch],
55 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
57 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
59 * Defined that server receives WHOIS command reply for private
60 and secret channels too. Updated protocol specs and the
61 code in server. Affected file silcd/command.c.
63 * Defined <channel user mode list> argument to WHOIS command
64 reply for returning user modes on the channels. The
65 channel list now doesn't include the user mode anymore but the
66 actual channel mode. Updated protocol specs and the code in
67 client and server. Affected files are silcd/command_reply.c,
68 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
69 and lib/silcclient/command_reply.c.
71 * Save the channels list in WHOIS command reply in normal server
72 so that WHOIS always shows joined channels also in normal
73 server and not just on router. Affected file is
74 silcd/command_reply.c.
76 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

85 not provided then the command merely returns the current mode
86 mask to the client. Updated protocol specs and the server.
87 Affected file is silcd/command.c.
89 * Added SILC session detachment/resuming support. It is possible
90 to detach by closing the network connection and then re-connect
91 and resume to the old client session. Added DETACHED user
92 mode that server will set for detached client. Added new
93 packet RESUME_CLIENT which is used to perform the resuming
94 process. Added DETACH command. Updated the protocol specs,
95 core library, client and server. Protocol TODO #22. Very
96 many affected files around the tree.
98 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
100 * Changed the CMODE's mode mask argument to be optional. If
101 not provided then the command merely returns the current mode
102 mask to the client. Updated protocol specs and the server.
103 Affected file is silcd/command.c.
105 * Changed the Killer's Client ID in KILLED notify to be just
106 any ID payload since router server is allowed to kill as well.
107 Updated protocol specs, client libary and server. Affected
108 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
109 and irssi/src/silc/core/client_ops.c.
111 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
113 * Added new user modes ANONYMOUS for special anonymous servers
114 that may set the mode for client, and BLOCK_PRIVMSG which
115 client may set to block incoming private messages unless the
116 Private Message Key flag is set (using private keys to protect
117 private messages). Updated protocol specs and code in client
118 and server and core library. Protocol TODO #23. Affected
119 files are lib/silccore/silcmode.h, silcd/server.[ch],
120 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
121 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
123 * Added new channel user mode BLOCK_MESSAGES which the client
124 may set to itself to tell server not send channel messages.
125 Other packets such as channel key packets are still sent.
126 Protocol TODO #23. Updated the protocol specs, client and
127 server. Affected files are lib/silccore/silcmode.h,
128 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
129 lib/silcutil/silcutil.c, silcd/command.c, and
132 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
134 * Redefined the Status Payload to include now two 8 bit fields,
135 instead of one 16 bit field. This now makes it possible to
136 send list of errors. Updated the protocol specs and the code
137 in core library, client library and server. Protocol TODO #1.
138 Affected files are lib/silccore/silccommand.[ch],
139 lib/silcclient/command_reply.[ch], silcd/command.c,
140 silcd/command_reply.c and silcd/packet_receive.[ch].
142 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
144 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
145 must be handled by the application and should tell the application
146 that an error message was already printed, and it should print the
147 config coords (line, filename, ...). Affected files are
148 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
150 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
151 server config parsing code more readable.
153 Fixed a bug in the fetch_logging() config callback.
155 Affected files is silcd/serverconfig.c.
157 * Drop root privileges when started in foreground. Don't drop them
158 if debugging also. Affected file is silcd/silcd.c.

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

241 Protocol TODO #13. Affected files are silcd/command.c,
242 silcd/packet_receive.c, packet_send.[ch],
243 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
244 The killer's client entry is now returned to application in
245 the `notify' client operation.
247 * Fixed the Max Argument fields that had too large value set
248 in the protocol specs. Protocol TODO #14.
250 * Added the LEAVE command reply to return the ID of parted
251 channel. Updated protocol specs and implemented it to the
252 client and server. Protocol TODO #15. Affected files are
253 silcd/command.c, lib/silcclient/command_reply.c. The channel
254 entry is now returned to application in the `command_reply'
257 * Rewrote the version SKE version checking in client libary
258 and in server to use the silc_parse_version_string. Affected
259 files are lib/silcclient/protocol.c, silcd/protocol.c.
261 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
262 commands that was missing it, and updated protocol specs and
263 the server implementation. Protocol TODO #10. The affected
264 file is silcd/command.c.
266 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
267 generic reply to a generic request (REQUEST flag), and
268 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
269 way. A draft-riikonen-silc-flags-payloads-00.txt is written
270 to define the payload for DATA flag. Added the flags to
271 the implementation. Protocol TODO #9. Affected file is
272 lib/silccore/silcchannel.h.
274 Changed the client library to return the message length
275 to application as well in the channel_message and private_message
276 client operations. Affected files are
277 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
278 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
279 and lib/silcclient/client_ops_example.c.
281 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
282 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
283 the channel. Updated protocol specs and impelemented this
284 to client and server. Protocol TODO #6. Affected files are
285 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
286 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
288 Added new options m and M to CMODE command in Irssi SILC
289 client to set these modes.
291 * Deprecated all administrative commands from SILC protocol
292 since they are highly implementation specific commands.
293 Updated protocol specs. Moved the old commands in
294 implementations to private range of command types. Affected
295 files are silcd/command.c, lib/silcclient/command.c and
296 lib/silcclient/command_reply.c. Protocol TODO #8.
298 * Fixed a bug in server where sending unknown command crashes
299 the server. Affected file silcd/command.c.
301 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
303 * Added SILC_PROTOCOLVERSION macro to check protocol version
304 of a socket connection. The affected file is
305 lib/silcutil/silcsockconn.h.
307 * Added better error logging in rekey protocol. Affected file
310 * Do not check public key types in SKE during rekey. Affected
311 file lib/silcske/payload.c.
313 * Fixed the rekey protocol with PFS, which was totally broken.
314 Affected file silcd/protocol.c.
316 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
318 * Some client implementations quit network by doing first LEAVE
319 and then immediately SIGNOFF (like Bombyx). We now do check
320 after a short time after LEAVE notify and check whether the
321 client is still valid after LEAVE, and if not we remove it from
322 cache. Affected file is lib/silcclient/client_notify.c.
324 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
326 * Merged version 1.1.4 of zlib. Even if it not currently in use,
327 it's good not to have security holes here.
329 * Fixed a negative refcount situtuation for the config context.
330 Affected file is silcd/serverconfig.c.
332 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
334 * ROBOdoc documented lib/silcutil/silcutil.h.
336 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Optimized even more the SilcPacketContext structure. Now
339 totally saved 16 bytes of memory per context after optimization.
340 Affected files are lib/silccore/silcpacket.[ch].
342 * Made strict checks for valid SILC IDs. Affected file is
343 lib/silccore/silcid.c.
345 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
347 * Changed the object argument for silc_cipher_register,
348 silc_hash_register, silc_hmac_register and silc_pkcs_register
349 to const. Affected files are lib/silccrypt/silccipher.[ch],
350 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
352 * Changed the silc_get_username and silc_get_real_name to
353 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
355 * Fixed the Irssi SILC Client to use the silc_get_username and
356 silc_get_real_name insted of glib routines since the glib
357 routines only corrupt stack. Fixes the Irssi SILC to work in
358 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
360 * Fixed the Irssi to not use g_get_home_dir since it crashes
361 or returns garbage on cygwin and corrupts stack. Added function
362 get_home_dir to Irssi routines. Affected files are
363 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
365 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Made some structure optimizations. SFTP memory FS MemFSEntry
368 entry structure. Optimized SilcTask structure. Optimized
369 SilcPacketContext structure.
371 Affected files lib/silcsftp/sftp_fs_memory.c,
372 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
374 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
376 * And yet again reverted back the config thing since Johnny
377 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
380 * Fixed memory leaks from config object. Affected files are
381 silcd/serverconfig.[ch].
383 * Added support for adding new connections to the server in rehash.
384 After rehash they take effect.
386 Added support for changing the maximum allowed connections in
387 rehash. The number can grow but going smaller is not supported.
389 Added function silc_server_num_sockets_by_remote to the
390 silcd/server_util.[ch].
392 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
394 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
396 * Added preliminary checking during config parsing for a valid
397 public/private key and removed further checks in the code.
398 Affected files are silcd/serverconfig.[ch], server.c.
400 * Moved functions silc_server_drop() and silc_server_daemonise()
401 from server.c to silcd.c since they are stricly related to
402 the application activity.
404 * Reverted a small part of the automatic ref/unref since
405 it caused a double unref in some situations. Affected
406 files are silcd/silcd.[ch], server.c, serverconfig.c.
408 * Added some .cvsignore files in the lib directory.
410 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
412 * Fixed silc_net_gethostbyaddr to correctly resolve by
413 address. Affected file lib/silcutil/silcnet.c.
415 * Fixed the notify relaying to client. The HMAC to be used
416 with relayed packets ws wrong and caused decryption failure
417 at the client end. Affected file is silcd/packet_receive.c.
419 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Created new branch silc_protocol_1_0_branch.
423 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
425 * Changed the silc_server_config_* routines to be SilcServer
426 independent. They are now officially application specific code
427 and not part of generic server implementation. Affected files
428 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
430 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
432 * Added automatic referencing of config context in the
433 silc_server_config_alloc, and automatic unreferencing in the
434 silc_server_config_destroy. Affected files are
435 silcd/serverconfig.[ch], silcd/silcd.c.
437 * Fixed the silc_log_quick handling in the logging routines.
438 It didn't log quickly when it was TRUE. Affected file is
439 lib/silcutil/silclog.c. Also the flush delay was set even
440 if it was 0 in config file. Affected file is
441 silcd/serverconfig.c.
443 * Added support for changing key pair of the server in rehash.
444 Affected file silcd/server.c.
446 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
448 * Fixed the TOPIC_SET notify to not cras. It changed the topic
449 too early, before getting the channel entry. Affected file
450 is silcd/packet_receive.c.
452 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
454 * Added functions silc_server_config_[ref/unref], these are used
455 to prevent that the config object is destroyed.
457 No longer directly affect global variables silc_log_quick and
458 silc_log_delay, they are first cached inside the config object
459 and then applied with silc_server_config_setlogfiles().
461 silc_server_config_set_defaults() is now internal to
462 serverconfig.c, there are no reasons to show this internal stuff
465 Affected files are silcd/serverconfig.[ch].
467 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
468 fprintf's to stderr, since some code may be executed again after
469 the server went into the background. Affected files are
472 * Added rehash support. Added function silc_server_rehash() that
473 will perform all the basic tasks of the rehashing procedure.
475 * Added command line option `-x, --hexdump'. This will enable the
476 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
477 The option `--hexdump' implies `--debug'.
479 * Fixed a bad bug in the logging APIs (silcutil library) where
480 the application would crash after calling silc_log_reset_all().
482 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Fixed the KICKED notify handling in client library to
485 correctly remove the channel and all entries from the
486 channel when I was kicked. This bug crashed the client.
488 Fixed yet another but in KICKED notify handling to remove
489 the kicked client correctly from the channel.
491 Affected file is lib/silcclient/client_notify.c.
493 * Fixed a minor bug in looking up correct client entry
494 in KICKED notify in server. Affected file is
495 silcd/packet_receive.c.
497 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
498 sources correctly to distribution. Fixes --with-gmp option.
500 * Removed the manual rehashing from ID Cache, and changed it
501 to use the SILC Hash Table's auto rehash feature. Affected
502 file is lib/silccore/silcidcache.c.
504 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Fixed a bug in the silc_client_nickname_format function that
507 handles the multiple same nickname formatting. Two clients
508 with same nickname caused problems after the first one left
509 and rejoined. It didn't format the nickname correctly.
510 Affected file is lib/silcclient/idlist.c.
512 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Don't change the topic if olod topic is same as new one.
515 Affected file is silcd/packet_receive.c.
517 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * Added cross-reference support to the SILC Documentation
520 generator. All types across all HTML files are now cross-
521 referenced. Affected files util/robodoc/generator.c and
522 scripts/silcdoc/silcdoc.
524 * Added file lib/silcutil/silctypes.h to include all the
525 arithmetic type definitions and some macros. Removed
526 includes/bitmove.h and moved macros to silctypes.h.
528 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
530 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
532 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
534 * Added `type' argument to silc_id_payload_parse_id function which
535 now returns the type of the ID to the sent pointer. Affected
536 file is lib/silccore/silcid.[ch].
538 * Added check for CMODE_CHANGE notify type that mode change is
539 allowed by the sender. Affected file silcd/packet_receive.c.
541 * Added check for CUMODE_CHANGE notify type that mode change is
542 allowed by the sender. Affected file silcd/packet_receive.c.
543 Added the ID type as CUMODE_CHANGE notify type as argument
544 to the `notify' client operation. Affected files are
545 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
547 * Added function silc_client_add_server to the client library.
548 Added support for resolving also channel and server info when
549 received unknown entity in notify packet. Affected files are
550 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
552 * Added function silc_command_get_status to return the command
553 status from the command reply's argument payload. Affected files
554 are lib/silccore/silccommand.[ch].
556 * Added check for KICKED notify type that the kicking is
557 allowed by the client. Affected file silcd/packet_receive.c.
559 * Created function silc_get_input which can be used to get input
560 (echo on or off) from user on command line. Affected files are
561 lib/silcutil/silcutil.[ch].
563 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
565 * Optimized silc_server_packet_relay_to_channel function.
566 Added new function silc_channel_message_payload_encrypt which
567 can be called directly if channel message payload needs to
568 be encrypted and is already encoded (no need to call _encode
569 function). Packet relaying is now done by router without any
570 extra memory allocations. Affected files are
571 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
574 * Fixed the INVITE notify handling. It took wrong arguments
575 as invite list and invite delete. Affected file is
576 silcd/packet_receive.c.
578 * Added check for TOPIC_SET notify type that the topic change is
579 allowed by the client. Affected file silcd/packet_receive.c.
581 * Added check for INVITE notify type that inviting is allowed by
582 the client. Affected file silcd/packet_receive.c.
584 * Changed the silc_server_client_on_channel to return the
585 SilcChannelClientEntry as well. Moved the function
586 silc_server_check_cmode_rights to server_util.[ch].
587 Affected files are silcd/server_util.[ch], silcd/command.c.
589 * Added function silc_server_check_umode_rights to check whether
590 changing client's user mode is allowed. Added check for
591 UMODE_CHANGE notify type that the umode change is allowed
592 by the client. Affected files are silcd/server_util.[ch],
593 silcd/packet_receive.c and silcd/command.c.
595 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
597 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
598 ID length. It ignored that ID can be IPv6 based as well.
599 Affected file lib/silccore/silcpacket.h.
601 * Fixed the silc_id_id2str and silc_id_str2id to take the
602 IPv6 address offset's into consideration. Affecte file is
603 lib/silccore/silcid.c.
605 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Fixed the internal Unix scheduler functions to check for
608 NULL context they may receive. The affected file is
609 lib/silcutil/unix/silcunixschedule.c.
611 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
613 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
614 can specify different directory with --home command line
615 parameter. Affected files irssi/src/silc/core/client_ops.c,
618 * SILC-specific commands aren't now executed if the active server
619 isn't of SILC-type, so there won't be problems with having
620 IRC and SILC protocol support in same client. Affected files
621 irssi/src/silc/core/silc-channels.c, silc-servers.c,
624 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Improved the signal support in SILC Schedule. Added new
627 function silc_schedule_signal_call which is used by application
628 to mark a signal to be called. It is now safe to perform
629 any kind of tasks in signal callbacks since it is guaranteed
630 that the application specified signal callback is called
631 after the signal is over. Affected files are
632 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
634 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Added `name' field to SilcChannelPrivateKey to represent
637 application given name for the key. Moved also the context from
638 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
639 Added the `name' argument also to the function
640 silc_client_add_channel_private_key.
642 Added function silc_client_current_channel_private_key to set the
643 current channel private key in use.
645 Added "change" command to KEY command which can be used to change
646 the current channel private key. Bound the command also to
649 Also affected files lib/silcclient/client_channel.c,
650 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
652 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Added silc_rng_get_byte_fast function in to the
655 lib/silccrypt/silcrng.[ch].
657 * Changed the interface of silc_packet_assemble and the
658 silc_packet_send_prepare. If silc_packet_assmble is now
659 called the application does not call silc_packet_send_prepare
660 because the library will call it automatically. These
661 interfaces now also return a reference to the outgoing buffer
662 which includes the assembled packet, which the application can
663 use to encrypt the packet.
665 Affected files are lib/silccore/silcpacket.[ch],
666 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
667 silcd/packet_send.c, server_backup.c and packet_receive.c.
669 * Fixed a packet sending bug on very high load, where outgoing
670 packet queue wasn't handled correctly and packets got corrupted.
671 Affected files are lib/silcutil/*/silc*sockconn.c,
672 lib/silcclient/client.c and silcd/server.c.
674 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
676 * Added macro SILC_PACKET_DATALEN which can be used during
677 packet assembling to check whether the data to be added to
678 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
679 len is truncated until it fits it.
681 Added checks for maximum length of channel message payload and
682 private message payload also.
684 Added checks for maximum packet length in server and in
687 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
688 lib/silcclient/client.c, lib/silccore/silcchannel.c and
689 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
690 lib/silcclient/client_prvmsg.c.
692 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
694 * Added silc_server_packet_queue_purge call to the
695 silc_server_disconnect_remote to assure that all data in the
696 queue before disconnecting is sent to the network. Affected
699 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Added the deleting of server's own ID cache entry to the
702 silc_server_free function. Free also everything else that
703 has been allocated in silc_server_init. The affected file
706 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Added functions silc_parse_version_string, silc_version_to_num,
709 and silc_ske_parse_version to parse SILC protocol style version
710 strings. Affected files lib/silcutil/silcutil.[ch] and
711 lib/silcske/silcske.[ch].
713 * Added new configuration params: version_protocol, version_software
714 and version_software_vendor to specify what version the remote
715 host must at least be to be able to connect to server. The vendor
716 string can be regex matched too. Added new function
717 silc_server_connection_allowed to check maximum number of allowed
718 connections, and allowed versions for incoming connections.
719 Affected files are silcd/server.c, server_util.[ch] and
722 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Added preliminary support for signals in scheduler. The
725 signals we care about are now blocked always when the scheduler
726 is locked. This way we can synchronise the use of signal with
727 scheduler. It is guaranteed that when signal occurs the scheduler
728 is not locked, and thus new tasks can be safely added to the
731 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
732 to silc_schedule_internal_init and silc_schedule_internal_uninit.
733 Added new platform specific routines
734 silc_schedule_internal_signals_[un]block and
735 silc_schedule_internal_signal_[un]register.
737 Added new functions to SILC Schedule API:
738 silc_schedule_signal_[un]register. Each signal that application
739 is going to use should be registered to the scheduler.
741 Affected files are lib/silcutil/silcschedule.[ch],
742 lib/silcutil/*/silc*schedule.c.
744 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
746 * Check for unauthenticated client and server in the
747 silc_server_new_client and silc_server_new_server functions.
748 Affected file silcd/packet_receive.c.
750 * Added function silc_string_is_ascii to check whether given
751 string is 7-bit ASCII string. Affected files are
752 lib/silcutil/silcutil.[ch].
754 * Added function silc_id_is_valid_server_id into the
755 silcd/serverid.c and added checking for valid Server ID's in
756 silc_server_new_server. The Server ID must always be based
757 on the server's public IP address.
759 * Added logging of DISCONNECT packet message in the server.
760 Affected file silcd/server.c.
762 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
764 * Changed all library interfaces that use Global RNG to also
765 accept SilcRng as argument. Affected files are
766 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
767 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
768 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
769 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
772 * Added function silc_pkcs_generate_key to the
773 lib/silccrypt/silcpkcs.[ch] for applications so that they
774 don't need to do pkcs->pkcs->init calls anymore.
776 * Remove SilcSocketConnection from the SFTP API since it really
777 wasn't needed there. The application has the information
778 saved in its contexts anyway and the SFTP layer doesn't need
779 know about it. Affected files lib/silcsft/silcsftp.h and
780 lib/silcsftp/sftp_[server/client].c.
782 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
783 The SilcSimContext is not SilcSim.
785 * Fixed possible buffer overflows in silc_id_render in the
786 lib/silcutil/silcutil.c.
788 * On EPOC the global crypto module lists are not used at all
789 in the crypto library. Added support for using the constant
790 algorithm list on EPOC. Affected files are
791 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
794 * Fixed the handling of third parameter of KICKED notify, since
795 it was mistakenly updated to SILC Protocol 1.0 even though it
796 is to be included in 1.1. Since it is not in 1.0 it is not
797 mandatory, and this fix now handles it only if it is provided,
798 and it is not error if it is not provided. Affected file
799 lib/silcclient/client_notify.c.
801 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
804 client. Affected file irssi/src/silc/core/client_ops.c.
806 * Merged with Irssi 0.8.4 from irssi.org CVS.
808 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Check for valid socket connection in client entries before
811 sending any messages. Fixes a crash, but doesn't fix some
812 other underlaying bug that is lurking there. Affected
813 file silcd/packet_send.c.
815 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
817 * $usermode, $cumode and $cumode_space expandos shouldn't do
818 anything with non-SILC server records. Affected file
819 irssi/src/silc/core/silc-expandos.c
821 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
823 * Fixed the silc_net_check_[host/local]_by_sock to support
824 IPv6 bound sockets as well. Now they can return IPv6 addresses
825 as well. Affected file lib/silcutil/silcnet.c.
827 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
828 Affected lib/silcutil/unix/silcunixnet.c.
830 * Fixed ID rendering (at least on some platforms, not NetBSD)
831 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
833 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Added silc_hash_public_key and silc_hash_public_key_compare
836 functions to be used with SilcHashTable. They can be used to
837 hash public keys and compare public keys in hash table. Affected
838 file lib/silcutil/silcutil.[ch].
840 * Added support for specifying multiple public keys for Client
841 connection section in server configuration file. This makes it
842 possible to accept multiple public keys from same host, or to
843 make a section that accepts any incoming host, and have the
844 accepted public keys listed in the section.
846 Added functions silc_sever_[find/get]_public_key, added the
847 support for this actually to all connection sections but only
848 the Client section is currently allowed to specify multiple
851 Affected files are silcd/server.c, server_internal.h,
852 command.c, protocol.c, server_util.[ch], packet_receive.c.
854 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
856 * Merged Irssi 0.8.2 from irssi.org CVS.
858 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
860 * If silc_debug is TRUE, also output standard logging messages
861 to stderr with the debug output.
863 Made silc_log_reset_all() flushing all channels before returning.
864 Also fixed some documentation typos.
866 Affected files are lib/silcutil/silclog.[ch].
868 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed the server to check correctly the amount of connections
871 from single host, by checking also the type of the connection.
872 Fixed also the comparison of number of connections and number
873 of allowed connections. Affected files are silcd/server.c,
876 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
878 * Fixed the USERS command reply to save the user's mode on the
879 channel as well. Fixed JOIN command reply to check whether a
880 client is on channel already and not join it twice. Affected
881 file lib/silcclient/command_reply.c.
883 * Added new file silc-expandos.c into irssi/silc/core/ to return
884 various stuff for various signal for the statusbar etc. updating.
885 Now Irssi SILC client prints channel user modes etc. on the
888 * The user mode (like server/router operator changes) is now shown
889 on the Irssi SILC client's statusbar. The affected files are
890 irssi/src/silc/core/client_ops.c, silc-expandos.c.
892 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
894 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
895 to SILC_SCHEDULE_[UN]LOCK macros.
897 * Added more error printing to logs in server code. Affected
898 files silcd/server.c and silcd/protocol.c.
900 * Fixed -S option parsing in Irssi SILC Client. Affected file
901 irssi/src/silc/core/silc-core.c.
903 * Added silc_buffer_alloc_size function. Affected file is
904 lib/silcutil/silcbuffer.h.
906 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
909 constants. Affected files in
910 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
913 * Changed the internal SFTP Memory FS table to const. Affected
914 file lib/silcsftp/sftp_fs_memory.c.
916 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
918 * Fixed the buffer formatting and unformatting routines to
919 check the size of 64 bits types with sizeof(). Affected
920 file is lib/silcutil/silcbuffmt.c.
922 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
924 * Removed 0.6.x backwards support.
926 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
928 * Changed all integer type names:
929 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
930 to avoid collisions with other libraries using same type names
933 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
935 * Added `prefer_ipv6' argument to the functions
936 silc_net_gethostbyname[_async]. If it is TRUE it will return
937 IPv6 address over IPv4. If FALSE IPv4 address is returned
938 even if IPv6 address was found. Affected files
939 lib/silcutil/silcnet.[ch].
941 * Added support silc_net_create_connection[_async] to fallback
942 to IPv4 address if IPv6 address could not be used (like if
943 it doesn't work on a specific system). Affected file in
944 lib/silcutil/unix/silcunixnet.c.
946 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Added silc_schedule_reinit function to do the enlarging
949 of the max tasks handling capabilities of the scheduler.
950 Affected files lib/silcutil/silcschedule.[ch].
952 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
954 * Added automatic extern "C" { ... } for C++ compilers so the
955 application does not need to define them. Affected file
956 includes/silcincludes.h.
958 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
959 old name went against naming convention. Applications now
960 include "silcclient.h" instead of "clientlibincludes.h".
961 Removed includes/clientlibincludes.h, it is redundant now.
963 * Renamed includes/version.h to silcversion.h.
965 * Added really preliminary support for OS/2 into the util
966 library. Only thread & mutex API is implemented, others
967 are still to be implemented. Created the lib/silcutil/os2/
968 directory. Created also file includes/silcos2.h.
970 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
972 * Added preliminary BeOS support into the util library.
973 Created lib/silcutil/beos/, and implemented all the needed
974 functions to support SILC on BeOS. Created also file
977 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
979 * Added proper initializations to silc's irssi code, so it's
980 now possible to load it as module. Affected files
981 irssi/src/silc/core/silc-core.c,
982 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
984 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
986 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
989 * Fixed the silcdoc document generator to correct generate
990 docs from all kinds of filenames. Affected files are
991 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
993 * ROBOdoc documented lib/silcutil/silcmemory.h.
994 Added also new function silc_memdup.
996 * Removed lib/silcutil/silcbufutil.h and moved those routines
997 to the lib/silcutil/silcbuffer.h.
999 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * Added `user_count' to the SilcChannelEntry which now tells the
1002 number of users on the channel. The user count is now saved
1003 in normal server of global channels as well. Affected files
1004 silcd/server.c, idlist.h, packet_receive.c and command.c.
1006 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1007 include file utility functions.
1009 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1010 instead of calling directly OS routines.
1012 * Fixed NICK change printing in Irssi SILC Client. Fixed
1013 KICKED notify printing in Irssi SILC Client. Affected file
1014 irssi/src/silc/core/client_ops.c.
1016 * Fixed a NICK change bug in client library, to not recreate the
1017 client_entry->channels hash table everytime nick is changed.
1018 Affected file lib/silcclient/client.c.
1020 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1023 the SKE interface a bit.
1025 * Fixed padding problem in PKCS#1. The padding was not actually
1026 random since the random number generator was used incorrectly.
1027 This security bug affects only when encrypting with PKCS#1, and
1028 it is not currently used at all in SILC. SILC only use signing
1029 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1031 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1116 Added the configuration object to SilcServerConnection struct.
1117 Affected files silcd/server_internal.h, server.c.
1119 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1121 * Add the client on channel after it was resolved at the
1122 channel message receiving, and it was not already on the
1123 channel. Affected file lib/silcclient/client_channel.c.

1141 authentication to be set at the same time.
1143 Added `prefer_passphrase_auth' setting in config file which
1144 can be used to set to prefer passwd auth if both passwd and
1145 public key is set. If not set, public key is preferred.
1146 This has effect only when being initiator (responder will try
1149 Added support for authentication with passphrase and public key
1150 at the same time. The passphrase is tried first always since
1151 it is faster to check.
1153 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1155 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1157 * Merged the new SILC Config library, with the server parsing

1201 * Fixed the file transfer's key agreement payload to include
1202 zero port also if the hostname is NULL because it could not
1205 Call file transfer monitor callback now also if error occurs
1206 during key agreement protocol.
1208 Changed the silc_client_file_send interface to return the
1209 SilcClientFileError instead of session id. The session ID
1210 is returned into pointer provided as argument.
1212 Check that the file exists locally before sending the
1213 file transfer request at all.
1215 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1217 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1227 file lib/silcutil/silclog.c.
1229 * Fixed the channel message payload decryption in the function
1230 silc_channel_message_payload_decrypt to not modify the original
1231 buffer before it is verified that the message decrypted
1232 correctly. Otherwise, next time it is called with correct
1233 channel key it won't encrypt since the payload is corrupted.
1234 Affected file lib/silccore/silcchannel.c.
1236 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1246 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1248 * Fixed a bug in hash table internal routine for traversing
1249 the table with foreach callback. The current entry may
1250 become invalid in the callback but it was referenced after
1251 the callback returned.
1253 Do not allow auto rehashing of hash table during the
1254 silc_hash_table_foreach operation, for same reasons as it is
1255 not allowed for SilcHashTableList. Affected files are
1256 lib/silcutil/silchashtable.[ch].
1258 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1260 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1261 Win32 DLL. extern's in header files are now declared with
1264 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1266 * Fixed private message handling. It used some old code that
1267 caused the client to crash. Affecte file is
1268 lib/silcclient/client_prvmsg.c.
1270 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1272 * Added function silc_client_add_channel,
1273 silc_client_replace_channel_id, and removed functions
1274 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1275 from client library.
1277 * Added cross reference of the joined channels to the
1278 SilcClientEntry, and changed the SilcChannelEntry's
1279 users list to SilcHashTable. The affected files are
1280 lib/silcclient/idlist.[ch].
1282 * Fixed a bug in hash table tarversing. While the hash table
1283 is traversed with SilcHashTableList the table must not be
1284 rehashed. It is now guaranteed that auto rehashable tables
1285 are not rehashed while tarversing the list. Also defined that
1286 silc_hash_table_rehash must not be called while tarversing
1287 the table. Added function silc_hash_table_list_reset that must
1288 be called after the tarversing is over. The affected files are
1289 lib/silcutil/silchashtable.[ch].
1291 * Changed all hash table traversing to call the new
1292 silc_hash_table_list_reset in server and in client library.
1294 * Added function silc_client_on_channel to return the
1295 SilcChannelUser entry if the specified client entry is joined
1296 on the specified channel. This is exported to application as
1297 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1299 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Fixed founder regaining problem with JOIN command on normal
1302 server. The notify for mode change must be sent always and
1303 not only if !cmd->pending. Affected file silcd/command.c.
1305 * Fixed the WHOWAS command's reply sending to support the
1306 lists correctly. Affected file silcd/command.c.
1308 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1310 * When sending JOIN command to router for processing the
1311 sender's old command identifier was not saved back to the
1312 sender's command context, fixed now. The affected file is
1315 * Create the key in JOIN command of the router did not return
1316 the channel key, added check for this. Affected file is
1319 * Fixed a channel ID update bug in JOIN command reply. Do
1320 not directly upgrade the ID but call the function
1321 silc_idlist_replace_channel_id if the ID was changed.
1322 Affected file silcd/command_reply.c.
1324 * Fixed memory leaks from command calling if it would fail.
1325 Affected file silcd/command.c.
1327 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1337 * Removed TRQ from lib/trq, not needed anymore.
1339 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1340 with server connections. Later this will be configurable
1341 in config file after new config file is done. Affected file
1344 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * Fixed a crash in server related to channel announcements.
1347 Affected file silcd/server.c.
1349 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1351 * Fixed memory leaks in silc_server_create_new_channel*
1352 functions. Affected file silcd/server.c.
1354 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1355 which ID was changed. This way the router will send the
1356 user list for the channel again, and server won't be in
1357 desync in some rare circumstances. Affected file is
1358 silcd/packet_receive.c.
1360 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1362 * Check for NULL socket pointer in the function
1363 silc_server_packet_send_to_channel_real. Affected file

1372 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1374 * Added lib/silcclient/client_ops_example.h as an template
1375 file for application programmers to quickly start using
1376 the SilcClientOperation functions in their application.
1377 Updated the lib/silcclient/README as well to tell about this
1378 nice file made available.
1380 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1382 * Call silc_server_remove_from_channels when removing client
1383 entry when NO_SUCH_CLIENT_ID was received. Affected file
1384 is silcd/command_reply.c.
1386 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1388 * Added server & router operator statistics updating. Affected
1389 file silcd/packet_receive.c and silcd/command.c.
1391 * Fixed the SERVER_SIGNOFF notify handling on normal server
1392 not to save the history information for clients. Same was
1393 fixed earlier in remove_clients_by_server function, but not
1394 here. Affected file silcd/packet_receive.c.
1396 * Raised the default connection-retry count from 4 to 7 in
1397 server. Affected file silcd/server.h.
1399 * Cancel any possible reconnect timeouts when we start the
1400 key exchange. Affected file silcd/server.c.
1402 * Do not reconnect on connection failure when SCONNECT was
1403 given. Affected files silcd/server.[ch].
1405 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1407 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1409 * Fixed the NICK command to always give the unformatted
1410 nickname to the one giving the NICK command. If unformatted
1411 nickname is cached already it will be formatted and the
1412 local entry will always get the unformatted nickname.
1413 Affected file lib/silcclient/idlist.c.
1415 * Fixed some double frees from client library commands.
1416 Affected file is lib/silcclient/command.c.
1418 * Fixed CUMODE command in server to assure that no one can
1419 change founder's mode than the founder itself, there was a
1420 little bug. Affected file silcd/command.c.
1422 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1424 * Removed the SilcClientCommandDestructor from the client
1425 libary, it is not needed anymore. Affected files are
1426 lib/silcclient/silcapi.h, command[_reply].[ch],
1427 client_notify, idlist.c.
1429 * Fixed GETKEY command to first resolve client, and then
1430 resolve the server only if the client was not found, instead
1431 of resolving both at the same time. Affected file is
1432 lib/silcclient/command.c.
1434 * Added silc_client_start_key_exchange_cb and lookup the
1435 remote hostname and IP address before starting the key
1436 exchange with server. The affected file is
1437 lib/silcclient/client.c.
1439 * The server's public key is now saved using the IP address
1440 of the server and not the servername for the filename.
1441 The hostname public key filename is checked as an fall back
1442 method if the IP address based filename is not found.
1444 Fixed the GETKEY command to save the fetched server key
1445 in correct filename.
1447 Print the remote server's hostname now when new key is
1448 received during connection process. Affected file is
1449 irssi/src/silc/core/client_ops.c.
1451 * Return always our own public key to the client if it asks
1452 for it with GETKEY command. Affected file silcd/command.c.
1454 * Removed the use_auto_addr variable from default config
1455 file since it was in wrong section. Affected file is
1458 * Fixed TOPIC_CHANGE notification to not route it when it
1459 was sent using silc_server_send_notify_to_channel function.
1460 Affected file silcd/command.c.
1462 * Fixed silc_server_send_notify_kicked to send the kicker's
1463 Client ID also, it was missing. Affected files are
1464 silcd/command.c, silcd/packet_send.[ch].
1466 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1468 * Do not save client history information in SERVER_SIGNOFF.
1469 Fixes the bug in normal server that it does not detect
1470 the client becoming valid after the server becomes back
1471 online. Affected file silcd/server_util.c.
1473 * Added `sock_error' field into the SilcSocketConnection
1474 context. When error occurs during socket operation (read
1475 or write) the error is saved. Added also new function
1476 silc_socket_get_error to return human readable socket error
1477 message. Affected files are lib/silcutil/silcsockconn.[ch],
1478 lib/silcutil/unix/silcunixsockconn.c, and
1479 lib/silcutil/win32/silcwin32sockconn.c.
1481 * The server now prints the socket error message in the
1482 signoff for client. Affected file silcd/server.c.
1484 * Fixed the `created' channel information sending from router
1485 to server in JOIN command. Checks now whether the channel
1486 really was created or not and set it according that.
1488 Fixed the JOIN command to use the client entry's current
1489 ID during the joining procedure instead of the one it sent
1490 in the command (it is checked though), since it can change
1491 between the packet processing and command processing, and
1492 would just case unnecessary pain in the client end. Affected
1493 file silcd/command.c.
1495 * Fixed a channel key payload sending to use correct channel
1496 ID when the server was forced to change the channel's ID by
1497 router. Router sent the key payload with the old Channel ID.
1498 Affected file silcd/packet_receive.c.
1500 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1502 * Call silc_server_save_channel_key only if the key payload
1503 was provided in the JOIN command's command reply. Affected
1504 file silcd/command_reply.c.
1506 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1508 * Fixed silc_mp_sizeinbase to return the value correctly with
1509 MPI. Affected file lib/silcmath/mp_mpi.c.
1511 * Fixed the stop_server signal to correctly stop the scheduler
1512 and gracefully stop the server when SIGTERM or SIGINT signals
1513 are received. Affected file silcd/silcd.c.
1515 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1517 * Simple handling of TERM and HUP signals. Also added some log
1518 flushing call around. Affected file is
1521 * Fixed small bugs in silclog.c. Now buffering output will take
1522 effect after 10 seconds since startup: This will ensure that
1523 no important startup messages are lost. Also output redirection
1524 will preserve original format ([Date] [Type] message).
1525 Affected file is lib/silcutil/silclog.c.
1527 * Added two options to the config file, in the logging section:
1528 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1529 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1531 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1533 * Do not print the warning about log files not being initialized
1534 more than once to avoid excess logging. Affected file is
1535 lib/silcutil/silclog.c.
1537 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1538 the SIM copying in make install in Makefile.am.pre.
1540 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1542 * Rewritten silclog APIs. Globally interesting changes follows:
1543 silc_log_set_files() changed to silc_log_set_file().
1544 silc_log_set_callbacks() changed to silc_log_set_callback().
1545 ROBOdoc documented silclog header file.
1546 SilcLogCb now returns bool to wether inihibit the default
1547 handler or not (to keep the old behaviour return always TRUE).
1548 The new APIs should also fix the problem of the
1549 silcd_error.log file that was written in the current directory.
1552 Log files streams will remain opened after silc_log_set_file()
1553 call, means less CPU usage notably on high traffic servers.
1554 File streams are now full buffered, and flushed to the disk
1555 every 5 minutes, lesses HD activity and CPU usage.
1556 Messages can be redirected, allowing admins to configure
1557 one single logfile for all server messages.
1558 the silc_log_quick global variable to activate fast-logging.
1559 Affected files lib/silcutil/silclog.[ch]
1561 * Changed some code to conform new silclog APIs. Affected
1562 files are doc/example_silcd.conf.in, silcd/server.c
1563 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1566 * Fixed a memory leak that could occur in some situations.
1567 Affected file silcd/serverconfig.c.
1569 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1571 * Added the silc_client_del_client to remove the client from
1572 all channels as well. Affected file lib/silcclient/idlist.c.
1574 * Fixed the client library to correctly remove the client
1575 from all channels when the client entry is being destroyed.
1576 Affected file lib/silcclient/client_notify.c, command.c.
1578 * Added auto-nicking support to the client library. If the
1579 applicatio now sets client->nickname it will be sent to the
1580 server after connecting by the library. This way for example
1581 SILCNICK (or IRCNICK) environment variables will have effect
1582 and always change the nickname automatically to whatever
1583 it is wanted. Affected file lib/silcclient/client.[ch].
1585 * Renamed silc_server_command_bad_chars to the
1586 silc_server_name_bad_chars and moved it to the
1587 silcd/server_util.[ch]. Added also new function
1588 silc_server_name_modify_bad to return nickname that
1589 includes bad characters as new nickname without those
1590 bad characters. This check and modify is now used in
1591 silc_server_new_client when the username is initially set
1592 as nickname, so it must be checked to be valid nickname.
1593 Affected file silcd/packet_receive.c.
1595 * The nickname length is now taken from the packet for real
1596 and not trusted to strlen() since it clearly can return
1597 wrong length for nickname including bad characters. This
1598 also applies to channel names. Affected file silcd/command.c.
1600 * Removed the lib/silcsilm/modules directory. Modules are now
1601 compiled into the lib/silcsim. Fixed the copying of the
1602 modules to follow symbolic links in Makefile.am.pre.
1604 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Fixed silc_string_regexify list creation. Fixes bugs with
1607 BAN and INVITE commands in server. The affected file is
1608 lib/silcutil/unix/silcunixutil.c.
1610 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Removed the command destructor entirely from the server's
1613 command and command reply routines. It is not needed, and
1614 its usage was buggy and caused crashes. Affected files are
1615 silcd/command[_reply].[ch].
1617 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Cancel protocol and NULL sock->protocol if timeout
1620 occurred during protocol. Affected file silcd/server.c.
1622 * Cancel protocol timeouts always before calling the final
1623 callback, to assure that after final callback is called
1624 no other state will be called for the protocol anymore.
1625 Affected file silcd/protocol.c.
1627 * Print error log if incoming connection configuration could
1628 not be found. Affected file silcd/server.c.
1630 * Fixed JOIN command to correctly save the founder mode
1631 to the client on normal SILC server, when the channel
1632 was created by the router. Affected file silcd/command.c.
1634 * Fixed LIST command (hopefully) to send correct reply
1635 packets. Affected file silcd/command.c.
1637 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * The silc_packet_receive_process now returns FALSE if the
1640 read data was invalid packet, and TRUE if it was ok.
1642 The server now checks that if unauthenticated connection
1643 sends data and its processing fails the server will close
1644 the connection since it could be a malicious flooder.
1646 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1648 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Make sure the warning about error opening a log file is
1651 printed only once and not everytime it fails (produces
1652 too much useless log). Affected file lib/silcutil/silclog.c.
1654 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1656 * Made the silc_server_daemonise() function more readable.
1657 Affected file silcd/server.c.
1659 * Pid file is now optional, the user may comment it out from
1660 the config file. Removed define SILC_SERVER_PID_FILE, we
1661 don't need a default any longer. Affected file
1662 configure.in.pre, lib/Makefile.am.pre.
1664 * Make some use of the pid file. The server now dies at startup
1665 if it detects a valid pid file on his path. The server would
1666 die anyway in this circumstance, because of the bind() failure.
1667 Affected file silcd/silcd.c.
1669 * No longer compiling lib/dotconf.
1671 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Fixed JOIN command parsing not to crash. Affected file
1674 lib/silcclient/command.c.
1676 * Fied the NICK_CHANGE notify to add the new client entry
1677 even it is resolved. This removes an <[unknown]> nick
1678 thingy bug in the client. Affected file is
1679 lib/silcclient/client_notify.c.
1681 * Do not try to allocate 0 bytes (efence does not like it)
1682 in lib/silccore/silccomand.c when encoding payload.
1684 * Do not take IRCNICK as nickname in Irssi SILC client since
1685 it is not possible to set nickname before hand connecting
1686 the server (TODO has an entry about adding auto-nicking
1689 * Changed the silc_server_command_pending to check whether
1690 there already exists an pending entry with the specified
1691 command, command identifier and pending callback. This is
1692 to fix IDENTIFY and WHOIS related crashes that may register
1693 multiple pending commands with same identifier. Affected
1694 file silcd/command.c.
1696 * Fixed the server to reconnect to the router even if it
1697 was already reconnecting and EOF was received. This to
1698 fix a possibility that the server wouldn't ever try to
1699 auto-reconnect to the router. Affected file silcd/server.c.
1701 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Fixed the server's password authentication to use the
1704 length of the locally saved password, and not the one
1705 sent in the packet. Affected file silcd/protocol.c.
1707 * Fixed same password authentication problem in the
1708 Authentication Payload handling routines in
1709 lib/silccore/silcauth.c.
1711 * Yet another password authentication problem fixed with
1712 channel password handling in silcd/command.c.
1714 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * If first character of string in silc_parse_userfqdn is '@'
1717 then do not parse it. Affected file is
1718 lib/silcutil/silcutil.c.
1720 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Fixed minor bug in IDENTIFY command reply sending, which
1723 caused various weird problems during JOIN when it was
1724 resolving names for users. Affected file silcd/command.c.
1726 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Fixed the IDENTIFY command reply sending to chech better valid
1729 clients. It was possible to send incomplete list of replies.
1730 Affected file silcd/command.c.
1732 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1734 * Added silc_client_command[s]_[un]register functions now to
1735 dynamically register the commands in client library. Removed
1736 the static table of commands. This allows the client library
1737 to call commands without causing the application to know about
1738 what commands library has called.
1740 Removed the INFO command reply kludge to detect when the command
1741 was called by library. Now library use its own command reply
1742 function for INFO command.
1744 Added function silc_client_command_call to call a command.
1745 Application can use it to call command, not access the structure
1748 Now all commands that are sent by the client library (not
1749 explicitly sent by application) use own command reply functions.
1751 Affected files around lib/silcclient/ and in
1752 irssi/src/silc/core/.
1754 * Fixed the WHOIS command reply sending to chech better valid
1755 clients. It was possible to send incomplete list of replies.
1757 Fixed the WHOIS and IDENTIFY to send the request to router
1758 if normal server did not do it and did not find any results.
1760 Affected file silcd/command.c.
1762 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Moved the internal data from SilcClient context into its
1765 own file, not accesible to application. Affected files
1766 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1767 and other files in client library.
1769 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Added doc/examples installation target in Makefile.am.pre.
1774 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1777 commands the found client entry will be removed from the
1778 cache, after notifying application about the error. Affected
1779 file lib/silcclient/command_reply.c.
1781 * Changed the /MSG to check for exact nickname user gave, and
1782 not let `nick' match `nick@host' if it is only one found. Now,
1783 user must type the exact nickname (like nick@host2) even if
1784 there are no more than one same nicks found. This is to avoid
1785 a possibility of sending nickname to wrong nickname since
1786 `nick' could match `nick@host'. Affected file is
1787 irssi/src/core/silc-servers.c.
1789 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Do not print "you are now server operator" or similar when
1792 giving /away command. Affected files are
1793 irssi/src/silc/core/client_ops.c, silc-servers.h.
1795 * Made the silc_server_command_pending_error_check to send
1796 the same command reply payload it received back to the
1797 original sender of the command. This way all arguments
1798 that was received by the server will be received by the
1799 client too. Affected file silcd/command.c.
1801 * Added the silc_idcache_add to return the created cache entry
1802 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1804 * Add global clients to expire if they are not on any channel.
1805 This is because normal server will never know if they signoff
1806 if they are not on any channel. The cache expiry will take
1807 case of these entries. This is done by normal servers only.
1808 The affected files are silcd/command_reply.c,
1809 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1811 * If server receives invalid ID notification for WHOIS or
1812 IDENTIFY and the ID exists in the lists, it is removed.
1813 Affected file silcd/command_reply.c.
1815 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1816 in client then client entry that it matches is searched and
1817 the nickname is printed on the screen for user. Affected
1818 file irssi/src/silc/core/client_ops.c.
1820 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Use cache entry expire time in the LIST command reply to
1823 purge old entries from the cache after the LIST command
1824 reply has been received. This way we don't have non-existent
1825 entries in the cache for too long. Affected file is
1826 silcd/command_reply.c.
1828 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * If we are normal server, and we've not resolved client info
1831 in WHOIS or IDENTIFY from router, and it is global client,
1832 we'll check whether it is on some channel. If it is not
1833 then we cannot be sure about its validity and will resolve it
1834 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1835 file silcd/command.c.
1837 * Search channel by name (if possible) rather than by ID
1838 in IDENTIFY command's command reply. Affected file is
1839 silcd/command_reply.c.
1841 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1844 Updated specs and implemented it. Affected file silcd/command.c,
1845 silcd/packet_send.c and silcd/packet_receive.c.
1847 * Implemented the <founder auth> payload handling in the JOIN
1848 command. If provided all conditions for channel joining
1849 except requirement to provide correct passphrase can be
1850 overrided by the channel founder. Updated the protocol specs.
1851 Affected file silcd/command.c.
1853 Added support for founder auth in JOIN command in client
1854 library. Fixed the parsing of the JOIN command now to support
1855 all options as they should be. The affected file is
1856 lib/silcclient/command.c.
1858 * Optimized the WHOIS and IDENTIFY commands to send the request
1859 to router only if it includes nicknames or other names. If
1860 they include only IDs then check the local cache first before
1861 routing. Affected file is silcd/command.c.
1863 * Added channels topic announcements. Affected file is
1864 silcd/packet_receive.c and silcd/server.c.
1866 * Fixed the silc_server_send_notify_topic_set to really destine
1867 the packet to channel. Affected file silcd/packet_send.c.
1869 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1870 library. Affected file lib/silcclient/client_notify.c.
1872 * Added UMODE announcements. Affected file silcd/server.c.
1874 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Memory leak fixes in:
1878 lib/silcutil/silcsockconn.c
1879 lib/silcske/silcske.c
1880 lib/silcske/groups.c
1882 lib/silccrypt/silcpkcs.c
1883 lib/silccore/silccommand.c
1884 lib/silccore/silcidcache.c
1889 * ROBOdoc documented the lib/silcske/groups.h file and a
1890 bit changed the interface for better.
1892 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1894 * Update the client entry context in the ID cache after
1895 nick change. Affected file lib/silcclient/command.c.
1896 Fixes the CUMODE command when regaining founder privileges,
1897 and a little WHOIS problem.
1899 * Fixed silc_net_gethostbyname to correctly call the
1900 inet_ntop. Affected file lib/silcutil/silcnet.c.
1902 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1904 * Added IPv6 support checking to the configure.in.pre, added
1905 also --enable-ipv6 option to override the check. Affected
1906 file configure.in.pre.
1908 * The silc_thread_create now calls the start function
1909 directly if threads support is not compiled in. Removes
1910 ugly #ifdef's from generic code. Affected files are
1911 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1913 * Added silc_net_gethostby[name/addr]_async to asynchronously
1914 resolve. Affected files are lib/silcutil/silcnet.[ch].
1916 * Added support for rendering IPv6 based server, client and
1917 channel IDs. Affected file lib/silcutil/silcutil.c.
1919 * Added support for creating IPv6 based server IDs. Affected
1920 file is silcd/serverid.c.
1922 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1924 * Added silc_net_gethostby[addr/name] into the
1925 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1926 routines. Added silc_net_is_ip[4/6]. Affected file is
1927 lib/silcutil/unix/silcunixnet.c. All routines that take
1928 address as argument now supports both IPv4 and IPv6 addresses.
1930 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1932 * Fixed LIST command reply sending in server. Affected file
1935 * Server now sends the kicker's client ID in the KICK notify
1936 to the kicked client. Affected file silcd/command.c.
1938 * The client library now parses the kickers client ID and
1939 UI displays it. Affected files lib/silcclient/client_notify.c
1940 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1942 * Made all payload parsing function prototypes consistent.
1943 They all take now const unsigned char * and uint32 pair as
1944 the payload data instead of SilcBuffer. Changes all around
1945 the source tree. Other unsigned char* -> const unsigned char*
1946 changes around the tree as well.
1948 * Optimized SFTP client and server packet sending not to
1949 allocate new buffer for each packet but to recycle the
1950 first allocated buffer. Affected files are
1951 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1953 * Optimized the SFTP client to use SilcList instead of
1954 SilcDList for requests, because it is faster. Affected file
1955 is lib/silcsftp/sftp_client.c.
1957 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1958 into lib/silccore/silcid.[ch].
1960 Renamed silcpayload.[ch] into silcargument.[ch].
1962 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * If client entry is deleted with active key agreement
1965 session, abort the session.
1967 The silc_client_abort_key_agreement now calls the completion
1968 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1970 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1973 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Don't use __restrict in older GCC's. Affected file is
1976 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1978 * silc_net_localhost now attempts to reverse lookup the
1979 IP/hostname. Affected file lib/silcutil/silcnet.c.
1981 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1982 command. It can be used to gain founder privileges at
1983 the same time when joining the channel.
1985 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1986 kicker's client ID as well. Updated protocol specs.
1988 Defined that the server must send SILC_COMMAND_IDENTIFY
1989 command reply with error status to client who sent
1990 private message with invalid client ID.
1992 Updated the protocol specification.
1994 * Added silc_server_send_command_reply to send any
1995 command reply. Affected file silcd/packet_send.[ch].
1997 * Added silc_id_payload_encode_data to encode ID payload
1998 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2000 * The server now send IDENTIFY command reply with error
2001 status if client ID in private message is invalid. Affected
2002 file silcd/packet_receive.c.
2004 * Save the server key file with server's IP address in
2005 the filename instead of hostname. The affected file is
2006 irssi/src/silc/core/client_ops.c.
2008 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2013 * Added libtool support for compiling shared objects in
2014 lib/silcsim. Affected file configure.in.pre and
2015 lib/silcsim/Makefile.am. Original patch by cras.
2017 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Pid file configuration, and server's config file fixes
2020 patch by toma. Updated CREDITS file.
2022 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2024 * Fixed silc_client_channel_message to not try to decrypt
2025 the message twice if it resolved the destination client
2026 information. This could cause of dropping one channel
2027 message. Affected file lib/silcclient/client_channel.c.
2029 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2032 lib/silcclient/client.c. This function is used when the SILC
2033 Client is run under some other scheduler, or event loop or
2034 main loop. On GUI applications, for example this may be
2035 desired to used to run the client under the GUI application's
2036 main loop. Typically the GUI application would register an
2037 idle task that calls this function multiple times in a second
2038 to quickly process the SILC specific data.
2040 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2042 * Fixed silc_server_drop() for dropping the supplementary
2043 groups as well, this could cause a security hole on some
2046 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2051 * Write PID file after dropping privileges. Added -F option
2052 to run server on foreground. A patch by debolaz.
2053 Affected files silcd/server.c, silcd/silcd.c.
2055 * Fixed MOTD to return the MOTD file server name. Affected
2056 file silcd/command.c.
2058 * Added INFO command reply handling to the Irssi SILC Client.
2059 Affected file irssi/src/silc/core/client_ops.c.
2061 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2063 * Fixed the silc_idcache_list_* routines to really support
2064 the dynamic list. Fixes a crash. Affected file is
2065 lib/silccore/silcidcache.c.
2067 * Fixed the LIST command reply to really call LIST command's
2068 pending callbacks. Affected file silcd/command_reply.c.
2070 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Update conn->local_entry->nickname after giving NICK
2073 command. Affected file lib/silcclient/command.c.
2075 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2077 * Added the [pid] option to the silcd configuration file
2079 Affected files: serverconfig.[ch] and silcd.c
2081 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Save fingerprint in WHOIS command reply in server.
2084 Affected file silcd/command_reply.c.
2086 * Fixed NICK commands pending callback registration.
2087 Affected file lib/silcclient/command.c.
2089 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Use ++server->cmd_ident when sending commands in server,
2092 instead of random number. Affected file silcd/command.c.
2094 * Fixed GETKEY command reply to call actually GETKEY pending
2095 command callbacks. Affected file silcd/command_reply.c.
2097 * A bit stricter check for nicknames. Check for same nickname
2098 in NICK command also. Affected file silcd/command.c.
2100 * Do not call INFO command everytime client ID changes, only
2101 during first connecting. Affected file lib/silcclient/client.c.
2103 * Set the new nickname only after successful command reply for
2104 NICK command is returned by server. Affected file
2105 lib/silcclient/command.c.
2107 * Remove nicknames from nicklist during server_signoff notify.
2108 Should fix /NAMES bit more. The affected file is
2109 irssi/src/silc/core/silc-channels.c.
2111 * Added `fingerprint' field to the SilcIDListData in the
2112 silcd/idlist.h to hold the fingerprint of the client's
2115 Send the fingerprint of the client's public key in WHOIS
2118 Affected files silcd/command.c, and silcd/idlist.[ch].
2120 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2121 create fingerprint from given data.
2123 * Show the fingerprint of the client's public key in WHOIS.
2124 Affected files irssi/src/module-formats.[ch] and
2125 irssi/src/silc/core/client_ops.c.
2127 * Format the multiple same nicknames also during JOIN and
2128 NICK_CHANGE notifys. Affected file is
2129 lib/silcclient/client_notify.c.
2131 * Do not print error on screen for invalid private message
2132 payload since it can come if someone is sending private
2133 messages with wrong key. Affected file
2134 lib/silccore/silcprivate.c.
2136 * Fixed multiple concurrent /PING crash. Affected file
2137 lib/silcclient/command.c.
2139 * Changed the wrong ID encoding. All IP addresses must be
2140 in MSB first order in encoded format. They were encoded
2141 wrong and was in LSB format. Affected files are
2142 silcd/serverid.c, lib/silcutil/silcutil.c.
2144 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2146 * Call the `connect' client operation through the scheduler
2147 in case of error. Affected file lib/silcclient/client.c.
2149 * Call the `failure' client operation even if the error
2150 occurred locally during a protocol. Affected file is
2151 lib/silcclient/protocol.c.
2153 * Added support of sending LIST command to router from normal
2154 server. This way normal server can get list of all channels
2155 in the network too. Fixed the channel list sending in the
2156 server too. Affected files are silcd/command.c, and
2157 silcd/command_reply.[ch].
2159 * Added silc_server_update_channels_by_server and
2160 silc_server_remove_channels_by_server. They are used during
2161 disconnection of primary router and in backup router protocol.
2162 Affected file silcd/server_util.[ch], silcd/server.c and
2163 silcd/server_backup.c.
2165 * Fixed channel adding to global list in IDENTIFY command
2166 reply in server. Affected file silcd/command_reply.c.
2168 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2170 * If the incoming packet type is REKEY or REKEY_DONE process
2171 that packet always synchronously. Fixes yet another MAC
2172 failed error on slow (dialup) connections. Affected file
2173 lib/silcclient/client.c and silcd/server.c.
2175 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * Call check_version SKE callback for initiator too. Affected
2178 file lib/silcske/silcske.c.
2180 * Implemented fix for security hole found in the SKE that was
2181 fixed in the specification few days back; the initiator's
2182 public key is now added to the HASH value computation.
2183 Added backwards support for the old way of doing it too, for
2184 old clients and old servers. Affected file is
2185 lib/silcske/silcske.c.
2187 * Enabled mutual authentication by default in SKE. If initiator
2188 is not providing mutual authentication the responder will
2189 force it. This will provide the proof of posession of the
2190 private key for responder. The affected files are
2191 lib/silcclient/protocol.c and silcd/protocol.c.
2193 * Do not cache anymore the server's public key during SKE.
2194 We do mutual authentication so the proof of posession of
2195 private key is done, and if the server is authenticated in
2196 conn auth protocol with public key we must have the public
2197 key already. Affected file silcd/protocol.c.
2199 * Added new global debug variable: silc_debug_hexdump. If
2200 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2201 file lib/silcutil/silclog.[ch].
2203 * Fixed compilation warning due to char * -> const char *.
2204 Affected files lib/silcutil/silcnet.h, and
2205 lib/silccore/silcauth.[ch].
2207 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Fixed CMODE command when new channel key was created. If
2210 the creation failed the old key was removed. Next time giving
2211 same command would crash the server since the old key was
2212 freed already. Affected file silcd/command.c.
2214 * Fixed the silc_server_announce_get_channels to not crash
2215 on reconnect. Affected file silcd/server.c.
2217 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Added silc_log_set_debug_string function to set a regex
2220 string to match for debug output. Only the function names,
2221 or filenames matching the given debug string is actually
2222 printed. This way it is possible to filter out those debug
2223 strings that user is not interested in.
2225 Fixed a bug in silc_string_regexify.
2227 Affected files lib/silcutil/silclog.[ch], and
2228 lib/silcutil/unix/silcunixutil.c.
2230 * Changed the -d options in both server and Irssi SILC client
2231 to take the debug string as argument. Affected files
2232 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2234 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Added silc_hash_babbleprint to create a Bubble Babble
2237 Encoded fingerprint. The encoding is developed by Antti
2238 Huima (draft-huima-babble-01.txt), and it creates human
2239 readable strings out of binary data. Affected file
2240 lib/silccrypt/silchash.[ch].
2242 * Print the babble print now in addition of fingerprint as well
2243 in Irssi SILC client. Affected files are
2244 irssi/src/fe-common/silc/module-formats.[ch],
2245 irssi/src/fe-common/silc/core/client_ops.c.
2247 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * Fixed a security problem found in SKE. The initiator's
2250 public key too is now added to the HASH hash value creation
2251 which is signed by the responder to create the SIGN value.
2252 This will prevent anyone in the middle to lie to the responder
2253 about the initiator's public key. If this is done now, the
2254 man in the middle will get caught. Updated the protocol
2257 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Better installation directory handling. Configure module
2260 paths and other paths automatically to example_silc* files
2261 in doc/. A patch by toma.
2263 * Fixed compiler warning from MPI library, and from SILC RNG.
2266 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2267 It can be configured with ./configure. A patch by toma.
2269 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Find correct make to use in prepare-clean. A patch by
2272 toma. Affected file prepare-clean.
2274 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2276 * Added irssi variables use_auto_addr, auto_bind_ip,
2277 auto_bind_port and auto_public_ip.
2279 * Changed the interface for silc_client_send_key_agreement
2280 in lib/silcclient/silcapi.h
2284 irssi/src/silc/core/silc-core.c
2286 lib/silcclient/silcapi.h
2287 irssi/src/silc/core/silc-channels.c
2288 lib/silcclient/client_keyagr.c
2291 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Added silc_pkcs_public_key_compare to compare two
2294 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2296 * Check that the client who set the founder mode on the
2297 channel is the same client that is giving the founder
2298 mode to itself. It is done by comparing the saved public
2299 key (it is saved even in the authentication is passphrase).
2300 Affected file silcd/command.c.
2302 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * Do not process packet for disconnected socket connection.
2305 Affected file lib/silccore/silcpacket.c.
2307 * Process the DISCONNECT packet through scheduler in the
2308 client library. Affected file lib/silcclient/client.c.
2310 * Fixed the silc_client_packet_parse to not to increase
2311 the packet sequence number if the conn->sock and the
2312 current socket connection is not same. This can happen
2313 for example during key agreement when the conn includes
2314 multiple socket connections (listeners). Affected file
2315 lib/silcclient/client.c.
2317 * The sender of the file transfer request now provides also
2318 the pointer (listener) for the key exchange protocol. If
2319 the listener cannot be created then it sends empty key
2320 agreement and lets the receiver provide the listener.
2322 Added `local_ip' and `local_port' arguments to the
2323 silc_client_file_send. If they are provided they are used,
2324 if not then it will attempt to find local IP address, if
2325 not found or bind fails then the remote client will provide
2328 Affected files are lib/silcclient/client_ftp.c and
2329 lib/silcclient/silcapi.h.
2331 * Extended the FILE SEND command to support defining the
2332 local IP and port for key exchange listener. They are
2333 optional. Affected file irssi/src/silc/core/silc-servers.c.
2335 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2337 * Defined to WHOIS command reply the sending of fingerprint
2338 of the client's public key (if the proof of posession of the
2339 corresponding private key is verified by the server).
2340 Updated to the protocol specification.
2342 * Added support of receiving the client's public key's
2343 fingerprint in command reply in client library. Affected
2344 file is lib/silcclient/command_reply.c, and
2345 lib/silcclient/idlist.[ch].
2347 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Do not send over 128 chars long nickname to the server
2350 in NICK command. Affected file lib/silcclient/command.c.
2352 * Do not send over 256 chars long channel names to the server
2353 in JOIN command. Affected file lib/silcclient/command.c.
2355 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Assure that silc_server_close_connection cannot be called
2358 twice for same socket context. Affected file is
2361 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Send error message to application if opening file for
2364 writing during file transfer fails. Affected file is
2365 lib/silcclient/client_ftp.c.
2367 Remove all file transfer sessions for a client that we're
2368 removing from ID cache.
2370 Affected file is lib/silcclient/client_ftp.c.
2372 * Fixed silc_net_addr2bin to return correct address. Affected
2373 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2375 * Fixed file transfer session removing on signoff notify.
2376 Affected file irssi/src/silc/core/silc-servers.c.
2378 * Added the SilcClientFileError to be returned in the monitor
2379 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2380 Affected file lib/silcclient/silcapi.h.
2382 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Fixed a crash in silc_client_ftp_free_sessions and
2385 silc_client_ftp_session_free_client. Affected file
2386 lib/silcclient/client_ftp.c.
2388 * Added `disabled' field in the SilcChannelEntry in the server
2389 to indicate if the server entry is disabled. Affected file

2399 * Fixed a crash in client resolving in client_prvmsg.c in
2400 client library. Affected file lib/silcclient/client_prvmsg.c.
2402 * Do not actually remove the client directly from ID cache
2403 during SERVER_SIGNOFF, but invalidate it. This way we
2404 preserve the WHOWAS info for the client. Affected file
2405 silcd/server_util.c.
2407 * Fixed SERVER_SIGNOFF notify handling in the server. The
2408 server is now able to process incoming SERVER_SIGNOFF notify
2409 for a server that it doesn't even know about. It will remove
2410 the clients provided in the notify. Affected file
2411 silcd/packet_receive.c.
2413 * Check for partial packet in data queue after every packet that
2414 was found from the queue. Return and wait for more data if
2415 there is partial data in queue. Affected file is
2416 lib/silccore/silcpacket.c.
2418 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Added SilcClietFileError enum to indicate error in
2421 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2422 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2423 Affected files lib/silcclient/silcapi.h and
2424 lib/silcclient/client_ftp.c.
2426 * Check that newsize in silc_buffer_realloc is larger than
2427 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2429 * Added better monitor of file transfers. It now monitors
2430 key agreement protocol during the file transfer too. Added
2431 error reporting too. Affected files
2432 irssi/src/silc/core/silc-servers.c,
2433 irssi/src/fe-common/silc/module-formats.[ch].
2435 * Wrote a help file for FILE command.
2437 * Added silc_rng_global_get_byte_fast to get not-so-secure
2438 random data as fast as possible. Random data is read from
2439 /dev/urandom if available and from the SILC RNG if not
2440 available. It is used in padding generation. Affected file
2441 lib/silccrypt/silcrng.[ch].
2443 * All packets in client library are now processed synchronously.
2444 Optimized packet processing a lot. Affected file
2445 lib/silcclient/client.c.
2447 * All server connection packets are processing synchronously
2448 now in server, to optimize packet processing. Affected file
2451 * Include files are installed now only in Toolkit distribution
2452 if make install is given. Affected files: all Makefile.am's.
2454 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Assure that silc_client_notify_by_server_resolve does not
2457 resolve the client information multiple times. If it cannot
2458 be found by the first it cannot be found at all. Affected
2459 file lib/silcclient/client_notify.c.
2461 * Fixed WHOWAS command reply calling. Affected file
2462 lib/silcclient/command_reply.c.
2464 * Removed all references to silc_idlist_get_client from the
2465 Irssi SILC client since that call is internal call used by
2466 the library. The Irssi SILC client will use now client
2467 retrieval functions found in silcapi.h.
2469 * Fixed a bug in resolving nickname info before sending
2470 private message. It used freed memory. Affected file
2471 irssi/src/silc/core/silc-servers.c.
2473 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Assure my_channels statistics cannot go negative in server.
2476 Affected files silcd/server.c, silcd/server_util.c.
2478 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2492 * Added silc_net_localip to return local host's IP address.
2493 Affected file lib/silcutil/silcnet.[ch].
2495 * If key exchange or rekey protocol is active for a connection
2496 parse all packets syncronously since there might be packets
2497 in packet queue that we are not able to process without first
2498 processing packets before them. Affected file silcd/server,
2499 lib/silcclient/client.c.
2501 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2502 whether library should continue processing the packet.
2503 Affected file lib/silccore/silcpacket.h.
2505 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2506 SilcSFTPMonitorData to SFTP server to monitor various

2531 * Renamed silc_file_read and silc_file_write to functions
2532 silc_file_readfile and silc_file_writefile. Added function
2533 silc_file_open and silc_file_close. Affected files
2534 lib/silcutil/silcutil.[ch].
2536 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Resolve the client info when received private message or
2539 channel message for a client which nickname we don't know.
2540 Affected files lib/silcclient/client_prvmsg.c and
2541 lib/silcclient/client_channel.c.
2543 * Do not crash in /KEY if client is not connected. Affected

2547 lib/silcclient/idlist.h.
2549 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2550 is incomplete and is being resolved, it won't be resolved
2553 Make sure also that USERS command reply does not resolve
2554 twice information. Affected file is
2555 lib/silcclient/command_reply.c.
2557 Make sure that silc_client_get_clients_by_list does not
2558 resolve twice same information.
2560 * Check for valid client->id in the silc_server_free_client_data.
2561 Affected file silcd/server.c.
2563 * Fixed /GETKEY nick@server not to crash if the server entry
2564 is not found. Affected file lib/silcclient/command.c.
2566 * Fixed the silc_server_check_cmode_rights to check the
2567 requested modes correctly. Affected file silcd/command.c.
2569 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Better checks for non-printable chars in nick added.
2572 Affected file silcd/command.c.
2574 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Call the silc_server_udpate_servers_by_server in the
2577 primary router that comes back online in the backup resuming
2578 protocol. Otherwise it routes packets wrong. Affected file
2579 silcd/server_util.[ch], silcd/server_backup.c.
2581 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2584 lib/silcutil/silcbuffmt.[ch].
2586 * Redefined the SILC packet header to include the padding
2587 length. Affected file lib/silccore/silcpacket.[ch].
2589 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2590 length for maximum padding up to 128 bytes). Affected
2591 file lib/silccore/silcpacket.h.
2593 * Removed all backwards support for old 0.5.x MAC thingies.
2594 The SILC packet header change makes it impossible to be
2595 backwards compatible.
2597 * Send the ENDING packet with timeout in the backup resuming
2598 protocol. This is to assure that all routers has connected
2599 to the primary router. Affected file silcd/server_backup.c.
2601 * Changed the RNG to take the first IV from random data. It
2602 used to take it from zero actually. Changed the RNG also
2603 to use /dev/urandom during session. /dev/random is used
2604 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2606 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Changed the SILC packet header to have the first two bytes
2609 (the packet length) encrypted. Affected files aroung the
2610 code tree, lib/silccore/silcpacket.[ch]. Removed the
2611 SilcPacketCheckDecrypt callback. It is not needed anymore
2612 since the silc_packet_receive_process will determine now
2613 whether the packet is normal or special.
2615 * Implemented the unidirectional MAC keys. Affected files
2616 lib/silcske/silcske.c, silcd/protocol.c and
2617 lib/silcclient/protocol.c.
2619 * Implemented the packet sequence number to the MAC computation.
2620 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2621 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2622 lib/silcclient/protocol.c.

2626 * Allow backup router to announce servers. All servers
2627 announced by backup router are added to the global list
2628 automatically. Update hte server's socket to our primary
2629 router also when backup router announces a server.
2630 Affected file silcd/packet_receive.c.
2632 * Do not update the client->router in the function
2633 silc_server_udpate_clients_by_server if the client is on
2634 global list. We might fail to find any specific server
2635 for locally connected clients and local cell clients. They
2636 should still use the `from' and not `to' as client->router.
2637 This fixes backup router resuming protocol. Affected file
2638 silcd/server_util.c.
2640 * Decrease channel statistics count only if the channel
2641 deletion worked. Affected files are silcd/server.c and
2642 silcd/server_util.c.
2644 * Added silc_server_update_servers_by_server to update origin
2645 of all server entries. Used during backup router protocol.
2646 Affected files silcd/server_util.[ch], silcd/server.c. and
2647 silcd/backup_router.c.
2649 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2650 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2651 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2652 lib/silccrypt/silchmac.c.
2654 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Assure that router cannot reroute the same channel message
2657 to the sender. Affected file silcd/packet_receive.c.
2659 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Made better checks that the channel message is not sent
2662 to the router it came from. Affected file is
2663 silcd/packet_send.c. Fixed memory leak too.
2665 * Announce informations for incoming router connection, but
2666 only after checking if it is replaced by backup router.
2667 Affected file silcd/packet_receive.c.
2669 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Fixed the backup resuming protocol to work in multiple
2672 router environment. Affected file silcd/server_backup.c.
2674 * Route packet only to one router in the function
2675 silc_server_packet_send_to_channel. Affected file is
2676 silcd/packet_send.c.
2678 * Fixed silc_server_send_notify_dest to set the broadcast
2679 flag. Fixed the silc_server_send_notify_topic to actually
2680 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2681 Affected file silcd/packet_send.c.
2683 * Changed the SFTP Filesystem interface. Changed the
2684 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2685 the filesystem operation function. The SilcSFTPFilesystem
2686 is now a context that is allocated by all filesystem allocation
2687 functions and it already includes the operations structure
2688 and filesystem specific context. It is given as argument
2689 now to the silc_sftp_server_start. This made the interface
2690 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2691 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2693 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Changed the backup router adding and getting interfaces
2696 in the server. The router that will be replaced by the
2697 specified backup router is now sent as argument. Affected
2698 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2701 * Added silc_net_addr2bin_ne to return the binary form of
2702 the IP address in network byte order. Affected files
2703 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2705 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Check for existing server ID in silc_server_new_server
2708 and in silc_server_connect_to_router_final and remove the
2709 old entry if it exists. Affected file silcd/packet_receive.c,
2712 * Send the channel message always to only one router, either
2713 in upstream or downstream. Affected file is
2714 silcd/packet_send.c.
2716 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Wrote the definition of the backup resuming protocol to the
2719 protocol specification.
2721 * Removed one redundant channel key generation from normal
2722 server during joining procedure. Removed one redundant
2723 channel key sending from server to router during joining
2724 procedure. Affected file silcd/command.c.
2726 * Made minor bugfixes to the backup router resuming protocol.
2727 Affected file silcd/server_backup.c, server.c.
2729 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Added --disable-asm configuration option. Affected files
2732 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2735 * Implemented the backup resuming protocol that is used to
2736 resume the primary router position in the cell after the
2737 primary router comes back online. Affected files
2738 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2739 and silcd/server_util.[ch].
2741 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Sleep two (2) seconds after sending QUIT command to server.
2744 Affected file lib/silcclient/command.c.
2746 * Assure that if outgoing data buffer is pending do not force
2747 send any data. Affected file silcd/packet_send.c.
2749 * Assure that if outgoing data buffer is pending do not force
2750 send any data. Affected file lib/silcclient/client.c.
2752 * Implemented the backup router support when the primary router
2753 goes down. The servers and routers can now use the backup
2754 router as new primary router without loosing connectivity.
2756 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2759 in the server to indicate disabled entry. All data read
2760 from the connection will be ignored and no data is sent
2761 for entry that is disabled. Affected files are
2762 silcd/idlist.h, silcd/server.c.
2764 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Created SFTP client and server test programs in the
2767 lib/silcsftp/tests directory.
2769 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Implemented memory filesystem (virtual filesystem) for
2772 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2775 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * Implemented the SFTP (SSH File Transfer Protocol) to the
2778 lib/silcsftp. It includes SFTP client and SFTP server
2781 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Moved lib/silccore/silcprotocol.[ch] to the
2784 lib/silcutil library.
2786 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2787 take variable argument list pointer as argument. Affected
2788 file lib/silcutil/silcbuffmt.[ch].
2790 * Added silc_buffer_set function that is used to set data
2791 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2792 Affected file lib/silcutil/silcbuffer.h.
2794 * Changed various routines in the core library to use the new
2795 silc_buffer_set instead of allocating new buffer only for
2798 * Added 64-bit value formatting and unformatting support to the
2799 silc_buffer_[un]format routines. Affected file is
2800 lib/silcutil/silcbuffmt.[ch].
2802 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2803 to includes/bitmove.h.
2805 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Fixed channel user mode saving in client library. Affected
2808 file lib/silcclient/command[_reply].c.
2810 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Defined the file transfer to the SILC Protocol. Added
2813 new packet type SILC_PACKET_FTP and defined File Transfer
2814 Payload. The mandatory file transfer protocol is SFTP
2815 (SSH File Transfer Protocol). Affected file in addition
2816 of the internet draft is lib/silccore/silcpacket.h.
2818 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2819 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2820 is used as part of backup router protocol when the primary
2821 router of the cell is back online and wishes to resume
2822 the position as primary router.
2824 * Redefined the MAC generation keys in the protocol. The
2825 same key is not used anymore in both direction. Both
2826 direction will now use different keys for sending and
2827 receiving. This fixes a potential security flaw. This
2828 change causes incompatibilities in the protocol.
2830 * Redefined also the MAC computation from the packet.
2831 An packet sequence number is now added to the MAC
2832 computation. This prevents possible replay attacks against
2833 the protocol. This change too causes incompatibilities
2836 Added `sequence' field to the SilcPacketContext to hold
2837 the current sequence number for the packet.
2839 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Added `created' field to the SilcIDListData in the file
2842 silcd/idlist.h to indicate the time when the entry was
2845 * Added `created' field to the SilcChannelEntry too. Affected
2846 file silcd/idlist.h.
2848 * Added `creation_time' aguments to all the announcement functions
2849 in the server. If it is provided then only the entries that
2850 was created after the provided time frame are actually
2851 announced. Affected file silcd/server.[ch].
2853 * The protocol says that the Channel ID's IP address must be
2854 based on the router's IP address. Added check for this in
2855 the silc_server_new_channel when processing incoming New Channel
2856 Payload. Affected file silcd/packet_receive.c.
2858 * Print out the correct version with --version in SILC client.
2859 Affected file irssi/src/silc/core/silc-core.c.
2861 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Fixed WHOWAS command to check for completnes of the client
2864 entry always, not just when the command is coming from client.
2865 Affected file silcd/command.c.
2867 * Added new function silc_server_packet_queue_purge to purge the
2868 outgoing data queue to the network. After the function returns
2869 it is guaranteed that the outgoing packet queue is empty.
2870 Affected file silcd/packet_send.[ch].
2872 * Purge the outgoing packet queue in the rekey protocol's final
2873 callback to assure that all rekey packets go to the network
2874 before quitting the protocol. Affected file silcd/server.c.
2876 * Added silc_client_packet_queue_parse as similar function as
2877 in server to the client library. The affected file is
2878 lib/silcclient/client.c.
2880 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Splitted silcd/server.c and created silcd/server_util.[ch]
2883 for utility functions.
2885 * Added new socket flag SILC_SF_DISABLED to indicate that the
2886 connection is open but nothing can be sent to or received from
2887 the connection. Affected file lib/silcutil/silsockconn.[ch].
2888 The checking for disabled socket is checked in the low level
2889 silc_socket_write and silc_socket_read functions.
2891 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Allow only nicknames and channel names that fits into the
2894 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2896 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * When processing JOIN command reply in server check that if
2899 the channel exists in our global list we'll move it the local
2900 list. Affected file silcd/command_reply.c.
2902 * Fixed the check whether client is joined on the channel already
2903 in JOIN command. Affected file lib/silcclient/command.c.
2905 * Fixed the JOIN command reply to check whether the channel
2906 already exists. Affected file lib/silcclient/command_reply.c.
2908 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Added silc_ske_status_string to map the SKE error numbers
2911 to readable strings. The affected files are
2912 lib/silcske/silcske[_status].[ch].
2914 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Do not show the private channels on the WHOIS channel list
2917 as it is not allowed by the protocol. The affected file is
2920 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Assure that the packet length digged from the actual packet
2923 is something sensible in the silc_packet_decrypt_rest_special
2924 in lib/silccrypt/silcpacket.c.
2926 * Free and NULL the allocated pointer in silc_hmac_alloc if
2927 the HMAC allocation fails. The affected file is
2928 lib/silccrypt/silchmac.c.
2930 * Print the selected security properties to the log files in
2931 the server. Affected file silcd/protocol.c.
2933 * Add SKE's reference counter even if calling the completion
2934 callback manually. Otherwise it goes negative, although it
2935 does not cause any problems. The affected file is
2936 lib/silcske/silcske.c.
2938 * Remove the client entry with short timeout after giving the
2939 KILL command. Affected file lib/silcclient/command.c.
2941 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2942 case all found clients are already disconnected (WHOWAS would
2943 found them) in the server. Affected file silcd/command.c.
2945 * Update the last_receive (time of last data received) to be
2946 updated only when received private or channel message so that
2947 the idle time showed in WHOIS makes more sense.
2949 * Added boolean field `valid' in to the SilcClientEntry in the
2950 client library to indicate whether the entry is valid or not.
2951 This fixes the nickname change bug on channel when changing
2952 the nickname to be same than the old (like nick to Nick) the
2953 nickname formatter doesn't set the new nick anymore to Nick@host.
2954 Affected file lib/silcclient/idlist.[ch].
2956 * Now actually fixed the nickname changing on disconnection.
2957 Added new function silc_change_nick to the Irssi SILC Client.
2958 Affected file irssi/src/silc/core/client_ops.c,
2959 irssi/src/silc/core/silc-nicklist.[ch].
2961 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Check that the public key exists in the GETKEY command before
2964 trying to encode it. Affected file silcd/command.c.
2966 * Print some notifications on received public keys with GETKEY
2967 command in the Irssi SILC Client. Affected files are
2968 irssi/src/fe-common/silc/module-formats.[ch],
2969 irssi/src/silc/core/client_ops.c.
2971 * Use IDENTIFY command to resolve the server information in the
2972 GETKEY command instead of INFO command. Affected file
2973 lib/silcclient/command.c.
2975 * All command reply functions in the client library now calls
2976 the pending command reply callbacks even if an error has
2977 occurred. The server has done this a long time and now it was
2978 time to move the client library to this as well. Now all
2979 errors can be delivered back to the pending command reply
2980 callbacks if necessary. Affected files are
2981 lib/silcclient/command[_reply].[ch].
2983 * Change the nickname on disconnection back to the username
2984 because in reconnect the server will enforce it to it anyway.
2985 Affected file irssi/src/silc/core/silc-servers.c.
2987 * Fixed a config file parsing bug in the Irssi SILC client.
2988 Affected file irssi/src/silc/core/clientconfig.c.
2990 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * When printing the channel mode on JOIN, verify that the
2993 channel key and channel's HMAC are valid. Affected file
2994 irssi/src/silc/core/client_ops.c.
2996 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2999 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3000 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3002 * Removed channel key rekey task deleting from the function
3003 silc_server_save_channel_key. Affected file silcd/server.c.
3004 Added explicit timeout task context instead that is used to
3005 delete the task if we are registering a new task before the
3006 new task has elapsed.
3008 * When channel key rekey occurs the client library now saves
3009 the old channel key for a short period of time (10 seconds) and
3010 is able to use it in case some is still sending channel
3011 messages encrypted with the old key after the rekey. Affected
3012 file lib/silcclient/[idlist.h|client_channel.c].
3014 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Added check to the silc_server_new_id_real to not accept
3017 new ID if it is the sender's own ID. Affected file is
3018 silcd/packet_receive.c.
3020 * Assure that we do not announce ourself or the one we've
3021 sending our announcements when we're router and are announcing
3022 servers to our primary router. Affected file silcd/server.c.
3024 * Fixed silc_server_command_identify_check_client to assemble
3025 correct WHOIS packet. It send corrupted WHOIS packet and
3026 caused problem with router to router connections. Affected
3027 file silcd/command.c.
3029 Fixed also silc_server_command_whois_check the same way
3030 as for the IDENTIFY command.
3032 * Added new SilcIDListStatus to the server in the SilcIDListData
3033 structure. The status now includes the current status of
3034 the entry (like registered, resolved etc.). Affected file
3035 silcd/idlist.[ch]. Defined a bunch of different status types
3036 as well. This replaced the old boolean registered field as well.
3038 Added resolve_cmd_ident field to the SilcClientEntry structure
3039 too so that if the entry is for example being resolved so
3040 another command may attach to the same pending command reply
3041 without requiring to resolve the same entry again. This concept
3042 should optimize the WHOIS and the IDENTIFY resolving under
3043 heavy load by taking away unnecessary resolving for entries
3044 that are being resolved already.
3046 Added support for adding multiple pending commands for one
3047 command idenfier. Affected file silcd/command[_reply].[ch].
3049 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3050 before deleting the data. Otherwise the hash table will have
3051 freed data in comparison functions. Affected file is
3052 silcd/command_reply.c.
3054 * Fixed silc_idlist_replace_client_id to add the new entry to
3055 the cache with NULL nickname. Otherwise there will be invalid
3056 memory as the nickname after the nickname is freed. Affected
3057 file silcd/packet_receive.c.
3059 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3060 saved into wrong slots because the previous number of entries
3061 was not taken into account. Affected file silcd/idlist.c.
3062 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3064 * If we are router and we receive JOIN notify to a channel that
3065 does not have any users then notified client is marked as the
3066 channel founder, as it is it. The affected file is
3067 silcd/packet_receive.c
3069 * Added to the extended hash table API's table_del_*ext functions
3070 the destructor as argument too, so that the caller can decide
3071 which destructor to use or whether to use destructor at all.
3072 Affected file lib/silcutil/silchashtable.[ch].
3074 * Fixed ID Cache purging. It actually deleted the entries from
3075 the hash table after the data was freed. The hash table ended
3076 up comparing freed memory. The affected file is
3077 lib/silccore/silcidcache.c.
3079 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Fixed Irssi SILC client's KILL command's HELP syntax.
3083 * The USERS command now resolves the detailed user information
3084 if the userinfo field is missing. Affected file is
3085 lib/silcclient/command_reply.c.
3087 * Do not print error in silc_file_read if the read file does
3088 not exist. Just silently return NULL. Affected file is
3089 lib/silcutil/silcutil.c.
3091 * Fixed the silc_log_output to not wine about NULL filename
3092 and to not create some bogus " " filename. Affected file is
3093 lib/silcutil/silclog.c.
3095 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Fixed various printing bugs on the user interface in the
3098 Irssi SILC Client. Minor changes that were forgotten from
3101 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3103 * Fixed the configure.in.pre and the compilation and distribution
3104 environment to support the new autoconf 2.52. That version is
3105 now required to compile the CVS trunk.
3107 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3110 to generally parse user@fqdn format strings. Affected file
3111 lib/silcutil/silcutil.c.
3113 * Added nickname_format and nickname_force_format fields to the
3114 SilcClientParams structure. The first one defines the format
3115 for the nicknames that the library will enforce if the receives
3116 multiple same nicknames. The second one is boolean value and
3117 can be used to force the library to always enforce the format
3118 to the nicknames regardles whether there are multiple nicknames
3119 or not. This configurable formatting was employed to flexibly
3120 support accessing multiple nicknames from the user interface.
3121 The userinterface can now set the nicknames to what ever format
3122 they prefer. Affected file lib/silcclient/silcapi.h.
3124 Added function silc_client_nickname_format to the file
3125 lib/silcclient/idlist.c. It performs the nickname formatting.
3127 Added new field `hostname´ to the SilcClientEntry context.
3128 It holds the hostname of the client. Affected file is
3129 lib/silcclient/idlist.h.
3131 * Irssi SILC Client sets the nicknames in nick@hostn format.
3132 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3133 irssi/src/silc/core/silc-core.c.
3135 The WHOIS printing now also shows both the real nickname and
3136 the formatted nickname so that user knows how to access the
3137 user if there are multiple same nicknames cached. Affected
3138 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3139 printing formatting too to take the hostname now as a separate
3140 argument. The Affected file is
3141 irssi/src/fe-common/silc/modules-formats.[ch].
3143 * Changed the silc_client_get_clients_local to accept the formatted
3144 nickname as argument. It accepts the real nickname too but the
3145 formatted nickname can be used to find the true entry from
3146 multiple entries. Affected file lib/silcclient/silcapi.h and
3147 lib/silcclient/idlist.c.
3149 * Added nickname_format_parse field to the SilcClientParams.
3150 It is a callback function provided by the application to parse
3151 the nickname out of the formatted nickname string. The library
3152 calls it to get the nickname from the formatted string. Since
3153 the application generally knows better the format of the nickname
3154 string it parses it instead of the library, even though library
3155 encodes the formatted string. If the callback function is not
3156 provided then the library will use the string as is. The
3157 affected file is lib/silcclient/silcapi.h.
3159 * All the nickname strings passed to the client library in
3160 commands are now expected to be formatted nickname strings.
3161 If the command does not support the formatted nickname string
3162 it will assume that the sent string is the actual nickname.
3163 Affected file lib/silcclient/command.c.
3165 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Added public key authentication support to OPER and SILCOPER
3168 commands in the client library. Affected file is
3169 lib/silcclient/command.c.
3171 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Changed the get_auth_methdod client operation to be asynchronous.
3174 It can be async if the application resolves the authentication
3175 method from the server during the negotiation. Added new
3176 SilcGetAuthMeth completion callback that the application will
3177 call after resolving the authentication method.
3179 Added function silc_client_request_authentication_method that
3180 the application can use to resolve the authentication method
3181 from the server. Added also SilcConnectionAuthRequest callback
3182 that the library will call after the server has replied. The
3183 application can call this function if it does not know the
3184 current authentication method.
3186 Affected files are lib/silcclient/client.c and
3187 lib/silcclient/silcapi.h.
3189 * The Irssi SILC client now automatically resolves the authentication
3190 method incase any configuration information is not present (and
3191 currently there never is). The affected file is
3192 irssi/src/silc/core/client_ops.c.
3194 * Fixed public key authentication from the client library.
3195 Affected file lib/silcclient/protocol.c. Changed also the
3196 protocol specification about the public key authentication in
3197 the connection authentication protocol. The actual data to be
3198 signed is now computed with a hash function before signing.
3200 * Fixed the public key authentication from the server as well.
3201 Affected file silcd/protocol.c.
3203 * Removed the mlock()'s from the memory allocation routines.
3204 Affected file lib/silcutil/silcmemory.c. The ./configure does
3205 not check anymore for the mlock(). Affected file is
3208 * Fixed USERS command in server to allow the execution of the
3209 command for private and secret channels if the client sending
3210 the command is on the channel. Affected file silcd/command.c.
3212 * Fixed silc_client_get_clients_local to return the clients
3213 count correctly. It could return wrong value. Affected file
3214 lib/silcclient/idlist.c.
3216 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3219 types. The assembler optimizations seemed not to like 64-bit
3220 data types. The assmebler optimizations thus are now enabled
3221 also for BSD systems as opposed to only enable them for Linux.
3223 * Do not check for threads at all on BSD systems. Affected
3224 file configure.in.pre.
3226 * Removed -n and -h options from the Irssi SILC Client since
3227 they are not used in silc.
3229 * Fixed the prime generation to assure that the first digit
3230 of the generated random number is not zero since our conversion
3231 routines does not like number strings that starts with zero
3232 digit. If zero digit is seen the random number is regenerated.
3233 This caused some corrupted RSA keys when the zero first digit
3234 was met. Affected file lib/silcmath/silcprimegen.c.
3236 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Fixed WIN32 configuration in the ./configure script.
3239 Fixed to include xti.h on environments that has it.
3240 Patches by Carsten Ilchmann and andrew.
3242 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3244 * Changed the silc_id_create_client_id to be collision
3245 resistant. It is now assured that there cannot be created
3246 two same client ID's. I suspect that some weird bugs in
3247 the server were actually caused by duplicate Client IDs.
3248 Affected file silcd/serverid.[ch]. A router receiving
3249 new ID now also assures and informs the sending server
3250 if the ID caused collision.
3252 * Changed the silc_id_create_channel_id to also assure that
3253 there are no collisions.
3255 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Statement about ignoring the Mutual Authentication flag when
3258 performing rekey with PFS was a bit misleading. It is ignored
3259 if it was set in the initial negotiation, it cannot be even
3260 set in the rekey. Fixed in the ke-auth draft. Started the
3261 new versions of the protocol drafts in the doc/.
3263 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3265 * Fixed a bug in silc_client_command_identify_save when saving
3266 new channel information. The channel name was no duplicated
3267 and caused crash on exit. Affected file is
3268 lib/silcclient/command_reply.c.
3270 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Fixed the getkey command handling in the server. Send just
3273 empty OK reply to the sender if the key could not be fetched
3274 (but everything else was ok, like the key just was not available).
3275 Changed the public key parameter to optional in the protocol
3276 specs so that empty OK reply can be sent. Affected file
3279 Added a message to Irssi SILC client to tell to user if the
3280 server did not return a public key.
3282 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Fixed a channel key regeneration bug. It registered new
3285 timeout tasks exponentially until all system resources were
3286 used. Affected file silcd/server.c.
3288 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Added the SILC Document generator to the scripts/silcdoc.
3291 It can be used to generate the Toolkit Reference Manual out
3292 of the source tree. Internally it will also use the RoboDoc
3293 generator now imported in util/robodoc.
3295 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Added couple of return's in rekey protocol if error orccurred
3298 during the protocol. The execution must be terminated.
3299 Affected file silcd/protocol.c. Also, terminate the protocol
3300 always with timeout.
3302 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * The client's Client ID was created initally from the wrong
3305 nickname (it could have been in format nick@host) in the
3306 silc_server_new_client. Affected file silcd/packet_receive.c
3308 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3310 * Added some SILC_LOG_ERROR's to various error conditions
3311 if client could not be added to ID cache. Affected files
3312 silcd/packet_receive.c and silcd/server.c.
3314 * When client's sock->user_data is freed, NULL also the
3315 client->router and client->connection pointers. Added check
3316 for these pointers being NULL to various places around the
3317 code. Affected file silcd/server.c.
3319 * Added client->data.registered == TRUE checks to various
3320 places around the code to assure that unregistered client's
3321 are not handled when it is not allowed. Affected file
3324 * Added `bool registered' fields to all
3325 silc_idlist_[server|client]_get_* routines to indicate whether
3326 the fetched client needs to be registered or not. Affected
3327 file silcd/idlist.[ch].
3329 * Add your own entry as registered to the ID cache in the
3330 server. Affected file server.c.
3332 * Fixed a bug in silc_server_new_server. The SilcServer was
3333 set as the new server's context instead of SilcServerEntry.
3334 This naturally caused some weird bugs.
3336 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Do not delete the channel rekey task when adding it
3339 for in silc_server_create_channel_key.
3341 * Changed the silc_server_create_channel_key to return
3342 TRUE or FALSE to indicate the success of the channel key
3345 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Fixed MSVC++ project files and added missing files to
3348 Makefiles under win32/.
3350 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Do not add TCP_NODELAY flag if the operating system
3353 does not have it defined. Affected files are
3354 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3356 * Fixed buffer overflow from Irssi SILC Client. Affected
3357 file irssi/src/fe-common/core/themes.c.
3359 * Fixed double free in client library in the file
3360 lib/silcclient/client.c when disconnecting from server.
3362 * Applied double free patch from cras to Irssi SILC client.
3363 Affected files irssi/src/core/[modules/expandos].c
3365 * Fixed the disconnection handling to Irssi SILC Client.
3366 The application must call silc_client_close_connection
3367 in ops->connect client operation in case of failure of
3368 the connection. Affected file is
3369 irssi/src/silc/core/client_ops.c.
3371 * Do not set sock->protocol to NULL in the function
3372 silc_client_close_connection after executing the protocol's
3373 final callback since the sock might not be valid anymore.
3374 Affected file lib/silcclient/client.c.
3376 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3378 * Do not enable SILC_THREADS if the linking with libpthread
3379 did not happen. Affected file configure.in.pre.
3381 * Added notion to protocol specification that server must
3382 verify the sent authentication payload with CMODE when
3383 setting the channel founder key. Implemented it to the
3384 server. Affected file silcd/command.c.
3386 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Added _EXTRA_DIST SILC distribution variable to the
3389 distributions file. It is used to conditionally add extra
3390 files or directories to the specific distribution. Affected
3391 files ./prepare, Makefile.am.pre and distributions.
3393 Removed the `_' from the start of the distribution names.
3396 * Added README.WIN32 for instructions to compile the Toolkit
3399 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Fixed a double free in disconnection in the server. Affected
3402 file is silcd/server.c.
3404 * Fixed the lib/silcske/groups.c to work now also with GMP
3405 MP library. The string conversion did not work when using
3406 specific base and the base is indicated in the string as well.
3408 * Created win32/ directory which now includes MSVC++ specific
3409 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3410 It will appear only in the toolkit distribution
3412 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Changed the key material distribution function in case when
3415 the hash output is too short. The data is now concatenated
3416 a bit differently than it used to. Made the change to the
3417 SKE protocol specification.
3419 * Added better GMP detection to configure.in.pre. A patch
3422 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Fixed a minor bug in SKE that might cause some problem on
3425 some platforms. Affected file lib/silcske/silcske.c.
3427 * Added the cookie checking for initiator in the SKE. It checks
3428 that the responder returns the sent cookie unmodified. The
3429 affected file is lib/silcske/silcske.c. Added new SKE
3430 error type INVALID_COOKIE that can be sent during the
3431 negotiation. Fixed some memory leaks as well.
3433 * Added the "invalid cookie" error message to Irssi SILC client's
3436 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Added `task_max' field to the SilcClientParams to indicate
3439 the maximum tasks the scheduler can handle. If set to zero,
3440 default values are used. Affected file lib/silcclient/silcapi.h.
3442 * Fixed memory leaks in silc_client_close_connection. Affected
3443 file lib/silcclient/client.c.
3445 * Added silc_client_del_client_entry to client library to free
3446 all memory of given client entry. Affected file is
3447 lib/silcclient/idlist.[ch].
3449 * Added new functions silc_client_del_channel and
3450 silc_client_del_server to delete channel and server entries.
3451 Affected file lib/silcclient/[silcapi.h/idlist.c].
3453 * Removed silc_client_del_client_by_id from silcapi.h.
3455 * Fixed the INFO command to return the server's own info
3456 correctly when querying by Server ID. Affected file is
3459 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Removed the non-blocking settings in WIN32 code in the
3462 silc_sock_[read/write] and added SleepEx instead. Affected
3463 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3464 of input data is now checked with FIONREAD and ioctlsocket.
3466 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Call silc_schedule_task_del_by_context in the
3469 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3470 Affected file lib/silccore/silcprotocol.c.
3472 * Call silc_protocol_cancel for active protocols in the
3473 silc_server_close_connection if the funtion
3474 silc_server_free_sock_user_data has not been called.
3475 Affected file silcd/server.c.
3477 * Generic tasks cannot be deleted using the del_by_fd
3478 task deleting function since generic tasks does not match
3479 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3481 * Added a notion to SILCOPER help file that the SILCOPER works
3482 only on router server, not on normal server.
3484 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Added for WIN32 support for the new scheduler as well.
3487 Affected file lib/silcutil/win32/silcwin32schedule.c.
3489 * Fixed the SHA1 implementation to work on various platforms.
3491 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3494 API. It is part of the scheduler now. Everything else is
3495 as previously but some functions has changed their names.
3496 Checkout the lib/silcutil/silcschedule.h for the interface.
3497 Updated all applications to use the new interface. Affected
3498 files are lib/silcutil/silcschedule.[ch].
3500 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * Found a bug in the SKE implementation. The HASH value,
3503 specified by the protocol, was not computed correctly. The
3504 public key of the responder was not added to the computation
3505 even though it is mandatory. Affected file lib/silcske/silcske.c.
3506 This unfortunately causes incompatibilities with older
3507 clients and servers.
3509 * Added WIN32 specific network init and uninit functions:
3510 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3511 the Winsock2. Affected file lib/silcutil/silcnet.h and
3512 lib/silcutil/win32/silcwin32net.c.
3514 * Set the socket always to nonblocking mode on WIN32 after
3515 reading data or writing data. Affected file is
3516 lib/silcutil/win32/silcwin32sockconn.c.
3518 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Fixed various compilation problems under WIN32. Affected
3521 files lib/silcutil/win32/silcwin32thread.c and
3522 lib/silcutil/win32/silcwin32schedule.c.
3524 * Removed all _internal.h #includes from public header
3525 files. Internal headers must never be included from
3528 Removed also the lib/silcske/payload_internal.h file.
3530 * All include files that may be needed (public and some others
3531 included by the public headers) by application developers are
3532 now copied to the ./includes directory. It does not copy any
3533 internal headers. Affected file Makefile.defines.pre and all
3534 Makefile.am's under lib/ and subdirs.
3536 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Do not change the ~/.silc directory's permissions automatically.
3539 Affected file irssi/src/silc/core/clientutil.c.
3541 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Do not cancel the protocol in silc_server_close_connection
3544 it might cause recursion. Now cancelled in the function
3545 silc_server_free_sock_user_data. Affected file silcd/server.c.
3547 * Fixed the silc_server_remove_clients_by_server to regenerate
3548 the channel keys correctly finally. Added also new function
3549 silc_server_remove_clients_channels to actually do it.
3550 Affected file silcd/server.c.
3552 * Fixed the silc_server_new_channel to not crash by giving
3553 wrong router to the new channel. Affected file is
3554 silcd/packet_receive.c.
3556 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3558 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3559 which is given as argument to the silc_client_alloc now.
3560 It can be used to configure the client and set various parameters
3561 that affect the function of the client.
3563 * The USERS command in server did not check whether the channel
3564 is private or secret. Affected file silcd/command.c.
3566 * Added new argument to the USERS command in protocol specification.
3567 The USERS command now can take the channel name as argument
3568 as well. Added support for this in client and server and
3569 updated the protocol specs.
3571 * Completed the GETKEY command in client. It can be now used
3572 to fetch also servers public key not only some clients.
3573 Affected files lib/silcclient/command[_reply].c.
3575 * Added silc_client_get_server to return server entry by the
3576 server name. Affected files lib/silcclient/silcapi.h and
3579 * Redefined the IDENTIFY command in protocol specification to be
3580 more generic. It now can be used to query information about
3581 any entity in the SILC Network, including clients, servers and
3582 channels. The query may be based either the entity's name
3583 or the ID. Added support for this in both client and server.
3585 Affected files silcd/command.c and lib/silcclient/command.c
3586 and command_reply.c.
3588 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3589 the _from_client and _from_server functions. Affected file
3592 * Added silc_client_get_channel_by_id_resolve to the file
3593 lib/silcclient/silcapi.h to resolve channel information by
3594 its ID. Added also silc_client_get_channel_by_id that
3595 does not resolve it from the server.
3597 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3599 * Added SilcServerEntry context into the client library
3600 to represent one server. The INFO command now allocates
3601 these to save the resolved server info. For now on the
3602 client library will also keep information about servers,
3603 connected and resolved with INFO.
3605 The INFO command now allocates the SilcServerEntry context
3606 and saves the server info there. The COMMAND_REPLY in
3607 the INFO now returns the parameters to application in
3608 same order as defined in the protocol specification.
3610 The entries are cached in the client->server_cache.
3612 * The INFO command is now issued after received the Client ID
3613 from the server. Affected file lib/silcclient/client.c.
3615 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3616 to the application as the mode changer might be server.
3617 It is guaranteed that NULL is not returned anymore to the
3618 application. Affected file lib/silcclient/client_notify.c.
3620 The ID Type is now also passed to the application so that
3621 it can check whether the returned entry is SilcClientEntry
3624 Added new function silc_client_get_server_by_id to return
3625 the server entry by ID. Affected files are the
3626 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3628 * Do not create the channel in the Irssi SILC Client when issuing
3629 the JOIN command but when received the sucessful JOIN command
3630 reply. Otherwise the channel might get created even though we
3631 could not join it. The Affected file is
3632 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3634 * Fixed a channel joining bug in router. The router must also
3635 check the channel modes, invite and ban lists etc. when serving
3636 the JOIN command sent by normal server. Affected file is
3637 silcd/command.c. The router now resolves the client's
3638 information from the server who sent the JOIN command if it
3639 does not know it, and processes the JOIN command only after
3642 * Changed the SilcCommandCb to take new argument; void *context2.
3643 Affected file lib/silccore/silccommand.h
3645 The second argument in the command callbacks in the server now
3646 includes the SilcServerCommandReplyContext if the command was
3647 called as pending command callback from the command reply.
3648 Otherwise it is NULL. When called as pending the status of the
3649 command reply will be checked and if it was erronous the
3650 error will be sent to the original sender of the command.
3651 This way the client always receives the error messages even
3652 though the server was actually the one who received the error
3653 when it resent the command to router, for example. Affected
3654 files silcd/command[_reply].[ch].
3656 * Fixed sending WHOWAS command's error message to client if
3657 the requested client could not be found. It was missing.
3660 * Changed the CMODE and CUMODE commands reply arguments in the
3661 protocol specification. The Channel ID is now sent in both
3662 of the commands to identify the channel. Implemented this
3663 new feature to the client and server. Affected files
3664 lib/silcclient/command_reply.c and silcd/command.c.
3666 * Made better checks for invite and ban lists in the JOIN
3667 command in server. Affected file silcd/command.c.
3669 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3671 * The server now performs the incoming host IP/DNS lookup
3672 using the silc_socket_host_lookup and thus does not block
3673 the server anymore. Affected file silcd/server.c.
3675 * Completed the multi-thread support for SILC Scheduler in
3676 the lib/silcutil/silcschedule.c.
3678 * Fixed the configure.in.pre to detect the pthread correctly
3681 * Fixed a deadlock in silc_task_queue_wakeup in the file
3682 lib/silcutil/silctask.c.
3684 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3686 * Added new function silc_schedule_wakeup that is used in
3687 multi-threaded environment to wakeup the main thread's
3688 schduler. It needs to be used when a thread adds a new task
3689 or removes a task from task queues. After waking up, the
3690 scheduler will detect the task queue changes. If threads
3691 support is not compiled in this function has no effect.
3692 Implemented the wakeup mechanism to both Unix and WIN32
3693 systems. Affected files are lib/silcutil/silcschedule.[ch],
3694 lib/silcutil/unix/silcunixschedule.c and the
3695 lib/silcutil/win32/silcwin32schedule.c.
3697 * Added new function silc_task_queue_wakeup to wakeup the
3698 scheduler by the specified task queue. Affected file
3699 lib/silcutil/silctask.[ch].
3701 * The silc_socket_host_lookup_start now wakes up the scheduler
3702 after adding the timeout task. Affected file is
3703 lib/silcutil/silcsockconn.c.
3705 * The silc_socket_host_lookup is synchronous now if the threads
3706 support is not compiled in. However, the callback is still
3707 called asyncronously through the scheduler, anyway. Affected
3708 file lib/silcutil/silcsockconn.c.
3710 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Added new function silc_socket_host_lookup to perform
3713 asynchronous IP and FQDN lookups for the socket connection.
3714 Affected files lib/silcutil/silcsockconn.[ch].
3716 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3718 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3719 that may or may not compile the mutex support in.
3721 Changed the silc_mutex_alloc interface. It allocates the
3722 mutex now to the sent pointer and returns TRUE or FALSE.
3724 Affected file lib/silcutil/silcmutex.h.
3726 * Wrote the SILC Task Queue interface to support multi-threads.
3727 Affected file lib/silcutil/silctask.[ch].
3729 * Wrote the SILC Scheduler to support multi-threads. Affected
3730 file lib/silcutil/silcschedule.c.
3732 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3735 in lib/silcutil/win32/.
3737 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3739 * Defined SILC Mutex API and SILC Thread API and implemented
3740 them for Unix. Affected files are
3741 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3742 lib/silcutil/unix/silcunixmutex.c and
3743 lib/silcutil/unix/silcunixthread.c.
3745 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Fixed the silc_server_remove_clients_by_server's channel
3748 key re-generation. The hash table handling was incorrect
3749 and would not work with many channels. Affected file is
3752 * Fixed some memory leaks around the server code.
3754 * Rewrote the silc_server_get_users_on_channel to support IPv6
3755 based Client ID's. Affected file silcd/server.c.
3757 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3758 specification. However, a separate document must be written
3759 to define the detailed signing procedure and the payload
3760 associated with the flag. Defined the flag to the
3761 lib/silccore/silcchannel.h as well.
3763 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3765 * Changed the dynamic tables to static size tables in the
3766 lib/silccrypt/silchmac.c.
3768 * Removed GCC dependencies from the code. A patch by cras.
3770 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3772 * Do not show the error "Error receiving packet bla bla"
3773 in server if it really was not an error (-2 means that reading
3774 is pending). Affected file silcd/server.c.
3776 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Fixed a possible crash in silc_server_remove_clients_by_server
3779 in silcd/server.c. Fixed there also some memory leaks.
3781 * Fixed the silc_idlist_replace_client_id. It could replace
3782 wrong key in the hash table. Affected file silcd/idlist.c.
3784 * Do not check whether there are global users on the channel
3785 if the channel->global_users is FALSE. Affected functions
3786 silc_server_remove_from_one_channel and
3787 silc_server_remove_from_channels in silcd/server.c. Also,
3788 do not check if the removed client is local as we can be
3789 sure that global client was not removed from the channel
3790 and checking for global users is not needed.
3792 * The silc_server_remove_clients_by_server now re-generates
3793 the channel keys correctly for those channels that had
3794 clients removed from them. Affected file silcd/server.c.
3796 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3798 * Found the reason of random crashes in the server. We weren't
3799 ignoring the SIGPIPE signal (which can be sent in write())
3800 and it crashed the server. Affected file silcd/silcd.c.
3802 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3804 * Assure that sock->user_data is not NULL in the function
3805 silc_server_packet_send in silcd/packet_send.c.
3807 * Disconnect the remote connection if it could not be added
3808 to any ID lists in the server. The affected file is
3811 * Check in silc_server_packet_send[_real/dest] that the
3812 socket is not disconnecting and ignore the data if it is.
3813 Affected file silcd/packet_send.c.
3815 * Define inline to __inline on native WIN32 compilation.
3816 Affected file includes/silcwin32.h.
3818 * Added some explicit type casts for inline code since MSVC
3819 require them. Affected files lib/silcutil/silcbuffer.h,
3820 lib/trq/silcdlist.h and lib/trq/silclist.h.
3822 * Print warning in log files from now on if the packet
3823 decryption fails. Affected file silcd/server.c.
3825 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3827 * Changed the `say' client operation's interface to accept
3828 new `type' argument to indicate the type of the message sent
3829 by the library. The application may filter the library's
3830 messages according the type. The affected file is the
3831 lib/silcclient/silcapi.h.
3833 * Added two new functions to lib/silcclient/silcapi.h:
3834 silc_client_del_client and silc_client_del_client_by_id.
3835 Affected file lib/silcclient/idlist.c.
3837 * Moved the clientincludes.h from includes/ to silc/ and
3838 serverincludes.h from includes/ to silcd/.
3840 * The modes for the CMODE and CUMODE are now passed as
3841 uint32 for application with COMMAND_REPLY. The affected
3842 file is lib/silcclient/command_reply.c.
3844 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3846 * /WHOIS without arguments shows client's own information.
3847 Affected file lib/silcclient/command.c.
3849 * Changed PING to not accept any arguments. The specs
3850 says that client can ping only the connected server so
3851 requiring an argument is not needed. Affected file is
3852 lib/silcclient/command.c.
3854 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Fixed a fatal bug in private message sending and reception
3857 encryption and decryption when using private message keys.
3858 The implementation was incorrect and did not follow the
3859 specification. It causd that some of the message were
3860 lost since it did not use the sending and receiving keys
3861 as the protocol suggests. This has been fixed and will cause
3862 incompatibilities with older clients when sending private
3863 message encrypted with private message keys. Affected files
3864 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3865 and various other in Irssi SILC Client.
3867 Added `responder' boolean argument to the functions
3868 silc_client_add_private_message_key[_ske] to indicate when
3869 the key is added as responder or initiator of the key
3872 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Removed the silc_ske_check_version function and created
3875 a SilcSKECheckVersion callback. Added also a function
3876 silc_ske_set_callbacks that is now used to set all SKE
3877 callbacks. The callback functions are not given to
3878 the SKE functions anymore, but this function is used to
3881 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3883 * Added `silc_version' argument to the silc_client_alloc
3884 to define the version of the application for the library.
3885 The library will use the version string to compare it
3886 against the remote host's (usually a server) version
3887 string. Affected file lib/silcclient/silcapi.h
3889 * Added the KE protocol context to Key Agreement context
3890 in client library so that we can abort the SKE if it
3891 is in process when we get timeout. Affected file is
3892 lib/silcclient/client_keyagr.c.
3894 * Do not resolve the client ID forever if it returns in the
3895 first time that such client does not exist. This was done
3896 for example with private message. Affected file is
3897 lib/silcclient/client_prvmsg.c.
3899 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Do not add regex.h for WIN32. The affected file
3902 includes/silcincludes.h.
3904 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3905 not work yet 100%. It generates the DLL's automatically
3906 when compiling with --with-win32 under cygwin.
3908 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * lib/contrib/regex.c is not compiled on WIN32.
3912 * Added silc_net_get_socket_opt function to the
3913 lib/silcutil/silcnet.h.
3915 * Added includes/silcwin32.h for WIN32 specific includes
3918 * Do not use ptime structure or any of the posix process
3919 functions on WIN32 in lib/silccrypt/silrng.c.
3921 * Added silc_gettimeofday to provide generic function
3922 for struct timeval on all platforms. Added the function
3923 to lib/silcutil/silcutil.h.
3925 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3928 library as they clearly belong there. As a plus side we
3929 can make the actual socket connection routines platform
3932 Added also new generic function silc_socket_read and
3933 silc_socket_write (that used to be silc_packet_[read/write].
3934 The implementation of these are platform specific.
3936 * Added WIN32 specific routines of silc_socket_[read/write]
3937 to lib/silcutil/win32/silcwin32sockconn.c.
3939 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Added preliminary support for native WIN32 compilation under
3942 cygwin (using the -mno-cygwin option for GCC) to the
3943 ./configure.in.pre. The --with-win32 now prepares the
3944 compilation for native WIN32.
3946 * Rewrote the SILC Scheduler interface in the file
3947 lib/silcutil/silcschedule.h. The scheduler is now context
3948 based and does not have anymore any global static scheduler.
3949 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3950 and created lib/silcutil/win32 directory for WIN32 based
3953 * Added Unix specific network routines to the
3954 lib/silcutil/unix/silcunixnet.c and the old
3955 lib/silcutil/silcnet.c includes now only generic routines.
3957 Added WIN32 specific network routines to the
3958 lib/silcutil/win32/silcwin32net.c.
3960 * Added Unix specific utility functions from the
3961 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3963 * Added WIN32 SILC Scheduler to the file
3964 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3967 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3969 * Do not handle JOIN notify in the server if the target client
3970 is not registered (idata->registered == FALSE). The affected
3971 file is silcd/packet_receive.c.
3973 * Update the nickrec->founder in event_cumode in the Irssi SILC
3974 client. Affected file irssi/src/silc/core/silc-channels.c.
3976 * Fixed the CUMODE_CHANGE notify handling in the server when
3977 server and router are announcing their clients on channels.
3978 Now the mode changes are saved and notified correctly. The
3979 affected file is /silcd/packet_receive.c.
3981 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3982 They really did not replace the cache entry in the ID Cache.
3983 Now they do that. Affected file silcd/idlist.c.
3985 * Fixed the KICK notify handling in the Irssi SILC client to
3986 update the channel records so that the kicked client does not
3987 appear to be on the channel. The affected file is
3988 irssi/src/silc/core/silc-channels.c.
3990 * Always update the conn->current_channel when executing command
3991 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3993 * Fixed the KILL notify handling in Irssi SILC client to remove
3994 the killed client on all channels.
3996 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Fixed the silc_parse_command_line to remove extra spaces
3999 from the start and end of the arguments. Affected file is
4000 lib/silcutil/silcutil.c.
4002 * Cancel and free any active protocol in the function
4003 silc_server_close_connection. Affected file silcd/server.c.
4005 * Cancel and free any active protocol in the function
4006 silc_client_close_connction. Affected file is
4007 lib/silcclient/client.c.
4009 * Do not execute the KILL command for clients that are in
4010 history (ie. they are not in the network). Affected file is
4013 * Fixed KILL notify handling, client does not crash anymore.
4014 Affected file irssi/src/silc/core/silc-channels.c.
4016 * Reduced the default packet buffer size from 2048 to 1024 in
4017 lib/silccore/silcpacket.c.
4019 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4020 counter to the SKE context that is incresed when the SKE library
4021 performs async operation outside the library. If the outside
4022 process frees the SKE context and FREED status will be set
4023 and the library will detect after the sync operation that the
4024 libary is freed. The affected files are
4025 lib/silcske/silcske[_status].[ch].
4027 * Resolve the client entry information in the function
4028 silc_client_channel_message to assure that NULL pointer is not
4029 passed as client entry to the application. */
4031 * Fixed the task timeout calculation to assure that there is
4032 never negative timeouts. The affected file is
4033 lib/silcutil/silcschedule.c.
4035 * Fixed the channel user mode notification sending in server.
4036 It was sent point-to-point to the router (or to server by router)
4037 but it needs to be destined to a channel. The routines now
4038 supports sending the channel user mode notifys to the channels
4039 when announcing clients and channels. Affected files are
4040 silcd/server.c and silcd/packet_receive.c.
4042 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4043 It did not actually replace the old channel entry in the cache.
4044 Affected file lib/silcclient/client_notify.c.
4046 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Fixed a possible crash in silc_packet_send_prepare. It now
4049 assures always that there is enough space in the buffer and
4050 at the tail area of the buffer (for MAC).
4052 Fixed the inbound buffer reallocation in silc_packet_read.
4053 It was old code and did not handle the reallocation correctly.
4056 The affected file is lib/silccore/silcpacket.c.
4058 * Fixed buffer overflow in silc_parse_nickname in the file
4059 lib/silcutil/silcutil.c.
4061 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * make install generates new server keys only if there is not
4066 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4069 Added check that if the NOREPLY is set then we will not send
4070 the away message. This avoids infinite loop of away messages
4071 if both clients are away. The affected file is
4072 lib/silcclient/client_prvmsg.c.
4074 * Fixed client crash if /NICK was given without arguments.
4075 Affected file lib/silcclient/command.c.
4077 * Server does not send the invite list in INVITE command back
4078 to the client if the list was not altered. Added this notion
4079 to the protocol spec as well. Affected file silcd/command.c.
4081 Fixed possible crash in INVITE command by checking the
4082 value of silc_server_get_client_route command.
4084 * Fixed the INVITE notify type handling. The arguments are now
4085 taken in correct order and client does not crash. The affected
4086 file is irssi/src/silc/core/silc-channels.c.
4088 Removed the "Inviting xxx to channel" message from the
4089 client library away and let the application handle it.
4090 Affected file lib/silcclient/command.c. Added that message
4091 to Irssi SILC client's message formats.
4093 * Fixed CMODE command crash in client. It now checks the
4094 amount of arguments correctly and does not crash. The affected
4095 file is lib/silcclient/command.c.
4097 * Do not create new channel automatically in silc_channels_join
4098 but check whether the channel by that name already exists.
4099 Affected file irssi/silc/core/silc-channels.c.
4101 * Do not send the SERVER_SIGNOFF to router if the disconnected
4102 entity was the router. Affected file silcd/server.c.
4104 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4105 SILC client as it was missing from there.
4107 Added the handling of the KICK notify to the Irssi SILC client
4108 as it was missing. Added "you have been kicked" message to
4109 Irssi SILC client's message modules formats.
4111 Added the handing of the KILL notify to the Irssi SILC client
4112 as it was missing. Added the kill message module formats
4115 The affected file is irssi/src/silc/core/silc-channels.c.
4117 * The router did not save the channel mode the server announced.
4118 Affected file silcd/packet_receive.c.
4120 * Fixed a possible crash in INFO command in server. If the
4121 server did not provide the server info it crashed. Affected
4122 file silcd/command.c.
4124 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Fixed the GETKEY command in the server to check also the
4127 global list. Otherwise the GETKEY would not work correctly
4128 in normal SILC server. Affected file silcd/command.c.
4130 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Fixed GETKEY crash, it crashed if the command did not succseed.
4134 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4137 is now real and not just an macro interface to GMP.
4139 Removed the entire GMP from the source tree and imported new
4140 NSS MPI library instead. Reason for removing GMP is that it is
4141 extremely large and compiles extremely slow. The NSS MPI
4142 is only a few files and compiles in less than 10 seconds.
4143 The speed is also about the same as GMP. The MPI is imported
4144 to lib/silcmath/mpi.
4146 If the system has GMP installed we will still use the GMP.
4147 If it is not then the NSS MPI will be compiled.
4149 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Merged a long nickname (127 characters long) crash bugfix from
4152 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4154 * Merged a freed memory reference bugfix from Irssi CVS tree.
4155 Affected file irssi/src/core/commands.c.
4157 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Added the server's public key sving and verification to the
4160 server when performing the SKE. This was missing and the
4161 remote server's (or router's) public key was accepted without
4162 checking whether we have it previously or trust it at all.
4163 Affected file silcd/protocol.c.
4165 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Check in the silc_server_timeout_remote if protocol is active
4168 and make sure that the protocol's final callback is called so
4169 that all memory if freed. Affected file silcd/server.c.
4171 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * silc_server_whois_send_reply crashed the server if the nickname
4174 was 127 characters long. Affected file silcd/command.c.
4176 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Added sanity check to the silc_server_new_client. If the hostname
4179 is provided inside username then check that the provided hostname
4180 really is the same as the resolved one. If the hostname was not
4181 resolved then check it from the public key. Affected file is
4182 silcd/packet_receive.c.
4184 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4185 if the server disconnected us and the connection is not valid
4186 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4188 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4189 the library to the lib/silcutil/silcutil.[ch].
4191 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Close log file after open. Affected file
4194 lib/silcutil/silclog.c.
4196 * Check whether sock == NULL in silc_client_send_packet and return
4197 if it is. Affected file lib/silcclient/silcclient.c.
4199 * Check rec->entry == NULL in the Irssi SILC Client before
4200 sending the channel message. Affecte file is
4201 irssi/src/silc/core/silc-servers.c.
4203 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Merged a splitted window bugfix from Irssi CVS tree. The
4206 affected file is irssi/src/fe-text/textbuffer-view.c.
4208 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4209 It did not print nickname.
4211 * Improved the distributions system a bit.
4213 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4216 irssi/src/fe-text/gui-window.c.
4218 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4219 to in-active server. The affected file is
4220 irssi/src/silc/core/client_ops.c.
4222 * Resolve the client in USERS command reply if the entry does
4223 not have username resolved. The affected file is
4224 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4225 command to WHOIS command to really resolve stuff. The USERS
4226 is not used any more in any critical section so WHOIS can
4227 be used even though it might be slower than IDENTIFY.
4229 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4232 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Changed the protocol API a bit more consistent in the
4235 lib/silccore/silcprotocol.[ch].
4237 * Changed the following headers to ROBODoc format:
4239 lib/silccore/silcpayload.h
4240 lib/silccore/silcprotocol.h
4241 lib/silccore/silcsockconn.h
4243 All core library headers are now formatted.
4245 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Fixed a bug in Irssi SILC client; do not show that you are
4248 server/router operator if you really are not. Affected file is
4249 irssi/src/silc/core/client_ops.c.
4251 * Renamed silc_command_free_payload to silc_command_payload_free.
4252 Affected file lib/silccore/silccommand.h
4254 * Added silcmath.h to include the prototoypes of various routines
4255 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4258 * Changed the following headers to ROBODoc format:
4260 lib/silccore/silcchannel.h
4261 lib/silccore/silccommand.h
4262 lib/silccore/silcid.h
4263 lib/silccore/silcidcache.h
4264 lib/silccore/silcmode.h
4265 lib/silccore/silcnotify.h
4266 lib/silccore/silcpacket.h
4267 lib/silcmath/silcmath.h
4269 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Added checking to the server code not to start the server if
4272 ciphers and stuff are not configured properly. Affected files
4273 silcd/serverconfig.[h] and silcd/server.c.
4275 * Changed the layout of the header files of the public interfaces
4276 in the SILC libraries. The new layout supports ROBODoc
4277 documentation tool (and some others) so that it is easy to create
4278 a library reference manual. All the other headers and source
4279 code must still follow the CodingStyle document. Also source
4280 code must not include these ROBODoc stuffs, only the headers.
4281 Furthermore, all public interface headers must now be named
4282 by using `silc' prefix, example: silcapi.h, silccipher.h.
4283 Some files were renamed due to this. All the other headers
4284 must not be used as public interfaces. I will update the
4285 CodingStyle document later. Changed following headers, so far:
4287 lib/silcclient/silcapi.h
4288 lib/silccore/silcauth.h
4289 lib/silccore/silcprivate.h
4290 lib/silccrypt/silcdh.h
4292 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Removed silc_client_packet_send_flush from the client library
4297 as it is not needed. Affected file lib/silcclient/client.[ch].
4299 * Added printing of message of unresolved authentication method
4300 to the Irssi SILC client. Added it to the module formats.
4301 Removed the same message from the client library.
4303 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Added new distribution feature, DISTLABEL. Every distribution
4306 can define own preprocessor label that can be used in the
4307 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4308 file distributions, acconfig.h.pre and prepare.
4310 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added Makefile.defines_int to include the actual definitions
4313 for Makefile.defines.in. Tested the new distribution system,
4314 created distributions and tested installation.
4316 * Added AWAY message printing to the Irssi SILC client. Added
4317 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4319 * Added SCONNECT command to call the SILC's CONNECT command.
4320 Cannot use CONNECT directly since Irssi uses that internally.
4321 Affected file irssi/src/silc/core/silc-servers.c.
4323 Added ACTION local command. It is same as ME command but takes
4324 the channel as mandatory argument.
4326 Rewrote some of the Irssi's help files to suite for SILC
4329 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Added Makefile.defines[.in] that should for now on be included
4332 in all Makefile.am file in the source tree. That file includes
4333 all common compilation definitions for SILC source tree.
4335 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Minor changes to the ./prepare script to change the package
4338 name according the distribution name to the configure.in.
4340 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Created new distribution system. Added file `distributions'
4343 that defines all the distributions that can be created out of
4344 the SILC source tree. The ./prepare script now reads that
4345 file to determine how to prepare the distributions. The
4346 first argument to the ./prepare is the name of the distribution
4347 and second is the version of the distribution. If given
4348 without arguments it creates the default (toolkit) distribution
4349 with the default version (defined in ./prepare).
4351 All Makefile.am files that are subject to the distributions
4352 are now named as Makefile.am.pre. These are ./Makefile.am
4353 and lib/Makefile.am. Others may be changed later.
4355 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Added invite list, ban list, some key management and connection
4358 error message printing to module formats in the Irssi SILC client.
4360 * Added new silc_client_set_away_message to set the away message
4361 that is back to the person who sent private message. The
4362 affected file lib/silcclient/silcapi.h and the
4363 lib/silcclient/client_prvmsg.c.
4365 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Fixed the private message sending in the Irssi SILC client,
4368 added local command KEY to the Irssi SILC client.
4370 Added key management and key agreement message formats to the
4371 irssi/src/fe-common/silc/module-formats.[ch].
4373 Added USERS (alias WHO) printing, server/router operator
4374 indication and LIST command printing to the module formats.
4376 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Fixed channel joining notify handling, cumode notify handling
4379 from Irssi SILC client.
4381 * Added SILC specific module-formats to the Irssi SILC client so
4382 that SILC specific message hilighting, colors etc is possible.
4383 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4385 Added channel mode, channel user mode, actions, notices,
4386 whois and whowas printing to the the module-formats.c.
4388 * Fixed a bug in channel deletion in the server. The channel
4389 is not left to the cache even if the channel founder auth mode
4390 is set when there are no users anymore on the channel. Affected
4391 file silcd/server.c.
4393 * The silc_net_localhost now resolves the entire hostname including
4394 the domain name. Affected file lib/silcutil/silcnet.c.
4396 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Changed the ask_passphrase client operation to be ascynchronous.
4399 It has now a completion callback and a context that the
4400 application must call after it has got the passphrase from
4401 the user. Affected files lib/silcclient/silcapi.h,
4402 lib/silcclient/protocol.c, lib/silcclient/command.c and
4405 Added SilcAskPassphrase callback that the application calls
4406 to deliver the passphrase to the library.
4408 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4409 The public key verification and especially a certificate
4410 verification is asynchronous procedure.
4412 Added new SILC_SKE_STATUS_PENDING status to indicate the
4413 request is pending and a callback will be called to finalize
4416 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4417 indicate that remote end did not send its public key (or
4418 certificate), even though we require it. Added check for this
4419 condition in the SKE. This was a security bug, now fixed.
4421 Defined new SilcSKEVerifyCbCompletion callback that is called
4422 when the verification process is completed.
4424 The affected files lib/silcske/silcske_status.h and
4425 lib/silcske/silcske.[ch].
4427 * Changed the verify_public_key client operation to be async
4428 as well. Defined SilcVerifyPublicKey callback that is used to
4429 indicate the success of the public key verification process.
4431 Changed the server and client to use the new async client
4434 * Changed the Irssi SILC client's internal scheduler to be called
4435 twice as many times as it used to be. As a result the client
4436 should be a bit faster now. Affected file is
4437 irssi/src/silc/core/silc-core.c.
4439 * Added support to Irssi SILC client of asynchronous public key
4440 verification and passphrase inquiry. Affected file is
4441 irssi/src/silc/core/silc-core.c.
4443 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Do not say "You have left channel %s" in client library.
4446 Moved it to the application. Affected files are
4447 lib/silcclient/command.c and silc/client_ops.c.
4449 * Fixed silc_client_get_clients. Command context was not
4450 duplicated and was freed memory in the callback. Affected
4451 file lib/silcclient/idlist.c.
4453 * Do not say "you are now talking..." on JOIN command in the
4454 client library. The appliation must handle it.
4456 * Do not say ".. changed topic to" in command reply in the
4457 client libary. The application must handle it.
4459 * Fixed TOPIC command sending in the client library.
4461 * Fixed a memory leak in silc_client_command_free in the file
4462 lib/silcclient/command.c.
4464 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Imported a modified version of Irssi client to the source tree.
4467 The Irssi will be used to create a new client called
4468 Irssi SILC. Imported to irssi/.
4470 Added silc_core_init_finish function to the Irssi. Affected
4471 file irssi/configure.in.
4473 A lot changes in the Makefile.ams around the irssi tree.
4475 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Do not rehash if the new size is same as the old size of the
4478 hash table, in the silc_hash_table_rehash*. The affected file
4479 lib/silcutil/silchashtable.c.
4481 * Replaced hash_table_del_by_context calls from the server
4482 (when channel->user_list and client->channels) to the
4483 hash_table_del as it is sufficient and faster.
4485 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Added silc_hash_table_list, silc_hash_table_get and the
4488 SilcHashTableList structure to provide an alternative way to
4489 traverse the hash table. The affected files are
4490 lib/silcutil/silchashtable.[ch].
4492 * Changed the server's idlist routines to use the hash table
4493 routines to optimize the code.
4495 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Replaced the client entry's `channel' list and channel entry's
4498 `user_list' list to hash tables for optimized lookup. Changed
4499 the code to use the hash table interface around the code.
4500 Affected file lib/silcd/idlist.[ch].
4502 * Added `auto_rehash' boolean argument to the function
4503 silc_hash_table_alloc to indicate whether the hash table should
4504 auto-rehash when it thinks is appropriate time. It will
4505 increase the hash table size if the there is twice as much
4506 entries in the table than the size of the table, and will
4507 decrease the size if there are twice as less entries than
4508 the size of the table.
4510 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4514 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * silc_idcache_purge_by_context deletes the entry now by context
4517 as it is supposed to do. Affected file lib/silccore/idcache.c.
4519 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4520 client is not anymore valid (WHOWAS givens the info) and not
4521 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4523 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Removed the `data' and `data_len' arguments from the ID Cache
4526 interfaces and added `name' argument. ID Cache does not handle
4527 anymore the binary data only a names associated with given ID.
4529 * When hashing a Client ID with silc_hash_id the entire ID is
4530 not hashed anymore, instead only the hash of the Client ID is
4531 hashed. This way we can access the Client ID from the cache
4532 with Client ID but with the hash of the ID (which is a hash of
4533 the nickname) as well without any difference in performance.
4535 Added also silc_idcache_find_by_id_one_ext to do one on one
4536 searching when we have the actual ID. Added also function
4537 silc_hash_client_id_compare. The affected files are
4538 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4540 * When hashing the name associated with a ID it is always done
4541 in lowercase. This way we can access the cache without worrying
4542 about case-sensitivity, even though, for example nicknames are
4545 * Fixed a bug in server with channel message sending. It put
4546 wrong ID type as destination ID. The affected file
4547 silcd/packet_send.c.
4549 * silc_idcache_del_by_context now deletes from all hash tables
4550 by context. Affected file lib/silccore/idcache.c.
4552 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Changed the client library to use the new ID Cache interface.
4555 Changes around the source tree.
4557 * Added silc_hash_table_rehash_ext to rehash with specific
4558 hash function. Affected file lib/silcutil/silchashtable.[ch].
4560 * Added silc_hash_string_compare to compare two strings in the
4561 hash table. Affected file lib/silcutil/silcutil.[ch].
4563 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Added new function silc_idcache_del_by_context into the
4566 lib/silccore/idcache.[ch].
4568 * Changed the server's ID list routines to use the new ID Cache
4569 interface. Changes around the source tree.
4571 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Added silc_hash_table_del[_by_context]_ext functions in to the
4574 lib/silcutil/silchashtable.[ch].
4576 Removed silc_hash_table_find_all* routines and added new
4577 silc_hash_table_find_foreach to replace them.
4579 Added silc_hash_table_replace_ext function as extended
4580 replacing function. Separated the simple hash table interface
4581 from the extended hash table interface in the file
4582 lib/silcutil/silchashtable.h.
4584 * Fixed minor bugs and changed it to use some of the new
4585 hash table functions in lib/silccore/idcache.c
4587 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Added new function silc_hash_table_find_all to return all keys
4590 in the hash table by the specified key. As the hash table is
4591 collision resistant it also makes it possible to have several
4592 duplicate keys in the hash table. This function may be used to
4593 find all of the keys from the hash.
4595 Added user_context arguments to the SilcHashFunction,
4596 SilcHashCompare and SilcHashDestructor to deliver user specified
4599 Added new fuctions silc_hash_table_find[_all]_ext to do
4600 extended lookup with specified hash and compare functions and
4601 specified user contexts.
4603 Added new function silc_hash_table_add_ext to add the key
4604 with specified hash function and user context.
4606 Added new function silc_hash_table_foreach to traverse all
4607 entrys in the hash table. Added SilcHashForeach callback
4610 Added new function silc_hash_table_del_by_context to delete
4611 the entry only if the context associated with the key matches.
4613 Affected files are lib/silcutil/silchashtable.[ch].
4615 * Removed silc_hash_[server/client/channel]_id and added just
4616 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4617 silc_hash_id_compare to compare two ID's using as the hash table
4618 comparison function. Added also silc_hash_data to hash
4619 binary data and silc_hash_data_compare to compare it.
4621 * Removed silc_idlist_find_client_by_hash as it is not needed
4622 anymore. Affected file silcd/idlist.[ch].
4624 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4625 to use internally the SilcHashTable. The new ID Cache is a lot
4626 faster than the old one. Some of the ID Cache interface was also
4627 rewritten and obsolete and stupid functions were removed.
4629 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added entry_count field to the SilcHashTable to keep the number
4632 of the entries in the table. Implemented the function
4633 silc_hash_table_rehash. Added new function
4634 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4636 Fixed a minor bug in silc_hash_table_free.
4638 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4639 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4640 into the lib/silcutil/silcutil.[ch].
4642 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Implemented a collision resistant hash table into the
4645 lib/silcutil/silchashtable[ch]. See the header and the source
4646 for the SilcHashTable API.
4648 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Merged dotconf version 1.0.2 into lib/dotconf.
4652 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Do not compile anything in lib/silcsim/* if the SIM support
4655 is not enabled. The tree should now compile without problems
4658 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Compiled the SILC under cygwin. Compiled and tested briefly
4661 without problems. More tests needed. The SIMs didn't compile
4664 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4666 * Fixed possible crash in silc_get_username in the
4667 lib/silcutil/silcutil.c.
4669 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Fixed a va_arg in silc/client_ops.c.
4673 * Oops, RC5 routines were named AES and caused some problems
4674 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4676 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Added new SilcIDIP structure into the lib/silccore/id.h and
4679 replaced the old `ip' fields from all SILC ID's to that type.
4680 This is a step towards IPv6 support.
4682 The silc_id_get_len takes now the ID as an extra argument.
4683 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4684 both IPv4 and IPv6 based ID's.
4686 The affected files are lib/silccore/id.[ch] and other files
4687 around the tree using these routines.
4689 * Removed the ID length arguments in server from various
4690 silc_server_send_notify_* routines -> they are not needed
4693 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Fixed memory leak in silc_encode_pem_file in the file
4696 lib/silcutil/silcutil.c.
4698 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Check minor version as well in the SKE. Affected files are
4701 silcd/protocol.c and lib/silcclient/protocol.c.
4703 * Added --identifier option to the server so that an identifier
4704 can be when creating the public key for the server. Affected
4705 file is silcd/silcd.c.
4707 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4708 lib/silccrypt/silcpkcs.c.
4710 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Register default ciphers and stuff when using -C option with
4713 the server. Affected file sildc/silcd.c.
4715 * Put back the servers public key filename format, it is better
4716 than the new one. For now, the client keys are saved with the
4717 new filename format. The affected file silc/client_ops.c.
4719 * Implemented the Cipher API for the rest of the ciphers that
4720 did not implement it or implemented it the wrong way.
4722 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Register default ciphers and stuff when using the -S option
4725 in the client. Affected file silc/silc.c. Same also when
4726 creating new key pair with -C option.
4728 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Fixed the silc_verify_public_key client operation function to
4731 save the public keys differently. The fingerprint is now
4732 used as filename and not the hostname. This way also the
4733 client keys are saved uniquely and not with hostnames. The
4734 affected file is silc/client_ops.c.
4736 * Trimmed the silc_hash_fingerprint function to remove extra
4737 whitespaces from the end of the fingerprint. The affected
4738 file is lib/silccrypt/silchash.c.
4742 * Added silc_cipher_register_default function to register all
4743 default ciphers. It can be used when configuration files
4744 does not exist and the application does not want any specific
4745 ciphers in any specific order.
4747 The SilcDList is now used as silc_cipher_list dynamically
4748 allocated cipher list. Removed the static list all together
4749 and now all ciphers must be allocated to the dynamic list.
4750 The silc_cipher_alloc routine was changed to check only the
4753 All silc_cipher_* routines that used to return int returns
4756 The affected files lib/silccrypt/silccrypt.[ch].
4758 * The same thing was done to silc_hash_* as for silc_cipher_*
4759 routines. Affected files lib/silccrypt/silchash.[ch].
4761 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4762 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4763 Added also silc_pkcs_[un]register[_default] functions.
4764 Removed the data_context from the PKCS API.
4766 * Added silc_hmac_register_default function to register default
4767 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4768 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4769 to unregister all hmacs at once.
4771 * Register the default ciphers, hash functions, PKCSs and HMACs
4772 if client's configuration file does not exist. The affected
4775 * The client did not load the hash functions from the SIM
4776 modules at all. Added support for this. Affected file is
4777 silc/clientconfig.c.
4779 * When decoding public key with silc_pkcs_public_key_decode, check
4780 the supported algorithm only if PKCS are registered. Affected
4781 file lib/silccrypt/silcpkcs.c. The same was done with the
4782 silc_pkcs_private_key_decode.
4784 * Fixed the SILC List routines to keep the list always in order.
4785 It used to change the list's order when traversing the list but
4786 not it preserves the order. Affected file lib/trq/silclist.h.
4788 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Added the client library to use the SilcSocketConnection's
4791 reference counter (by silc_socket_dup) to prevent the bug that
4792 the socket object may be freed underneath async operation.
4794 * The name resolv library checking fixes in the configure.in.pre.
4797 * Created new version of the protocol drafts for future
4798 development. The -03 drafts are the ones that will be changed
4799 in the trunk now and the -02 will remain as they are.
4801 * Send list of CUMODE notifys to the router when announcing
4802 the channel users to the router. Affected file silcd/server.c.
4803 If the router receiving channel founder CUMODE for a channel
4804 that already has channel founder it will send CUMODE notify
4805 to the sender to remove the channel founder rights from the
4806 announced client. Affected file silcd/packet_receive.c.
4808 * The CUMODE notify may now use Server ID as well as the entity
4809 who changes the mode. Updated protocool specs.
4811 * Updated INSTALL and README files.
4813 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * New web pages in the http://silc.pspt.fi. The pages was
4820 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Implemented the [DenyConnectin] config section in the server.
4823 Added silc_server_config_denied_conn to check whether incoming
4824 connection is denied. Affected file silcd/serverconfig.[ch].
4826 * Do not check the ports when checking the incoming configuration
4827 data if the port is 0, meaning any. Affected file is
4828 silcd/serverconfig.c.
4830 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Fixed buffer overflow in silc_string_compare in the file
4833 lib/silcutil/silcutil.c.
4835 * Fixed double free in silc_server_command_leave in the file
4838 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Fixed the version checking in the server. Affected file is
4843 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Fixed the configuration data fetching when accepting new
4846 connections in the server. Affected file silcd/server.c.
4848 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Added `sender_entry' argument to the function
4851 silc_server_packet_relay_to_channel so that we can check
4852 whether some destination actually belongs to the same route
4853 the sender belongs (ie, we must not resend the packet to the
4854 sender). Affected file silcd/packet_send.[ch].
4856 * Added `servername' field to the SilcClientEntry in the server
4857 to hold the name of the server where client is from. Affected
4858 file is silcd/idlist.h.
4860 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Moved the channel message encrypting in the router betwen
4863 router connections from silc_server_channel_message to the
4864 silc_server_packet_relay_to_channel since we want to check
4865 whether we have anybody channel before encrypting anything.
4866 Affected files silcd/packet_[receive/send].c.
4868 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Fixed the [AdminConnection] server config section to support
4871 multiple entries. Affected file silcd/serverconfig.c.
4873 * Added support into the server to check the validity of the
4874 incoming connection before executing any KE or authentication
4877 * The connection configuration is now saved to the KE and
4878 connection auth protocol contexts and not fetched anymore in
4879 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4881 * The local hosts listenning address and port is also resolved
4882 now when starting the server. We want to have the socket object
4883 to include the real address and port for the listener. Added
4884 new function silc_net_check_local_by_sock into the files
4885 lib/silcutil/silcnet.[ch].
4887 * Fixed a broadcast bug in server -> do not broadcast if we
4890 * Fixed a routing bug. Do not route broadcast packets ever.
4891 Broadcast packets must be processed always and not routed since
4892 they may be destined to some other host than yourself and thus
4893 would get routed without no good reason. Affected file is
4896 * Added function silc_server_config_is_primary_route to check
4897 whether primary router connection has been configured (a router
4898 configuration that we are initiating). If there is not, we
4899 will assume that there is only two routers in the SILC network
4900 and we will use the incoming router connection as our primary
4901 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4903 * Changed the order of the broadcasting. Broadcast _after_ the
4904 packet has been processed not before. Affected file is
4907 * Fixed a [ClientConnection] parsing bug. The port was never
4908 parsed correctly thus resulting to port 0. Affected file
4909 silcd/serverconfig.c.
4911 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4912 argument and did not set the broadcast packet flag. Affected
4913 file silcd/packet_send.c. Fixed same bug in the function
4914 silc_server_send_notify as well.
4916 * If we receive NEW_ID packet for our own ID in the server, ignore
4919 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Removed the nickname from the Private Message Payload.
4924 Updated the code and the protocol specs.
4926 * Updated protocol specs for submitting to the IETF.
4928 * Tweaked the Random Number Generator a bit. Affected file
4929 lib/silccrypt/silcrng.c. Exported a new function
4930 silc_rng_[global]_add_noise which can be used to add more
4933 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Do not parse packets with different timeout when protocol
4936 is active -> may cause problem with rekey. Affected file
4939 * When server receives signoff notify it must not create
4940 new channel key if the client is on any channels since the
4941 sender of the signoff notify will create it.
4943 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added printing of error messages during SKE protocol from the
4946 failure packet sent by server during SKE. Affected file
4949 * Removed the client's failure_callback handling with timeout
4950 and handle it immediately when received.
4952 * The SKE library returned wrong type in SUCCESS and FAILURE
4953 packets. They must be 32 bit MSB not 16 bit MSB.
4955 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Ok, rewrote the logic of the re-key and now it seems to work.
4958 I tested it on high traffic with frequent re-keys without
4959 problems. Added hmac_receive (and renamed hmac to hmac_send)
4960 in SilcClientConnection in lib/silcclient/client.h and
4961 in SilcIDListData in silcd/idlist.h. Also, removed the
4962 SilcPacketParserContext's cipher and hmac fields as they are
4963 not needed anymore and actually caused some problems when
4964 the ciphers and hmac's changed underneath the packet parser.
4966 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * If re-key protocol is active then process the incoming packets
4969 synchronously since we must assure that icoming packets encrypted
4970 with the old key is processed before the new keys is set to
4971 use. This is true other packets than for REKEY packets.
4972 Affected file silcd/server.c. The same was done to client library
4973 as well, affected file lib/silcclient/client.c.
4975 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Fixed bug in client and server to accept the force send if
4978 the packet is send from silc_[server/client]_packet_process
4979 function. Otherwise the packets are never delivered, oops.
4981 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Disable force sending of packets when REKEY protocol is active.
4984 We must assure that no packet is sent directly when rekey is
4985 performed. All packets must be sent through packet queue.
4986 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4987 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4988 function is silc_[server/client]_packet_send_real to check
4991 * Replaced the SIM paths from example config files to
4992 /usr/local/modules. Also, make install creates now
4993 /usr/local/silc/logs directory to hold all the SILC server
4996 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Made the configure.in.pre work on Solaris. Patch by salo.
5000 * Made all ciphers compatible with non-x86 machines. Defined
5001 CBC mode macros into lib/silccrypt/ciphers_def.h.
5003 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Fixed the make install.
5007 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * When MAC computation fails the silc_packet_decrypt returned 0
5010 even though it was supposed to return -1. Fixed this. The
5011 affected file is lib/silccore/silcpacket.c.
5013 * Do not replace the config files in /etc/silc (in make install)
5014 if they already exist. Affected file ./Makefile.am.
5016 * Do not send re-key packets immediately but through packet queue.
5017 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5019 * Changed silc_net_check_host_by_sock to return FALSE if the
5020 IP/DNS could not be resolved. Though, it returns the IP address
5021 now even if it could not resolve it (but returns also FALSE).
5022 Affected file lib/silcutil/silcnet.[ch].
5024 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added silc_pkcs_decode_identifier to decode the public key's
5027 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5028 Added also silc_pkcs_free_identifier. Added also new context
5029 SilcPublicKeyIdentifier.
5031 * Added -S option to the silc client. It is used to dump the
5032 contents of the specified public key file.
5034 * Changed the PKCS api to return the public key length when
5035 setting the public key.
5037 * Fixed a fatal bug in the public and private key file loading.
5038 Affected file lib/silccrypt/silcpkcs.c.
5040 * Execute the packet parsing for client with zero (0) timeout
5041 if the protocol is active. Affected file silcd/server.c.
5043 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Made the key generation options to the silcd program. Added
5046 -C option, equivalent to client's option.
5048 * Added new [ServerKeys] config section to the server. It
5049 configures the server's public and private key.
5051 * Defined generic Public Key Payload into the protocol
5052 specification to send specific type of public keys and
5055 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5056 public key or certificate.
5058 * Implemented the GETKEY command to the server and to the
5059 client library and on user interface.
5061 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Made preliminary `make install' work.
5065 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added SilcServerRekey context into silcd/idlist.h.
5069 * Added the PFS support as defined in the specification to the
5070 SKE protocol. Affected files lib/silcske/*.c.
5072 * Added `ske_group' field to the SilcServerRekey context to hold
5073 the number of the SKE group that is used with PFS in re-key.
5074 Affected file silcd/idlist.h.
5076 * Added PFS re-key support to the server. Affected file is
5079 * Added silc_protocol_cancel to cancel execution of the next
5080 state of the protocol. Affected file is
5081 lib/silccore/silcprotocol.[ch].
5083 * Added the re-key support with and without PFS to the client
5084 library. Re-key is performed once in an hour, by default.
5086 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5087 Added silc_client_rekey_callback and silc_client_rekey_final.
5088 Affected files are lib/silcclient/protocol.[ch] and
5089 lib/silcclient/client.[ch].
5091 * Removed the `hmac_key' and `hmac_key_len' fields from the
5092 SilcClientConnection structure; not needed. Affected file is
5093 lib/silcclient/client.h.
5097 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Do not ask whether user wants to use the negotiated private key
5100 for private messages, just use it. Affected file is
5101 silc/local_command.c.
5103 * Added `send_enc_key' and `enc_key_len' fields to the
5104 SilcIDListData structure since they are needed in the re-key
5105 phase. Affected file is silcd/idlist.[ch].
5107 * Implemented the simple re-key protocol into the server.
5108 Affected files silcd/server.c and silcd/protocol.[ch]. The
5109 re-key will be performed once in an hour, by default.
5111 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5112 Added silc_server_rekey, silc_server_rekey_callback and
5113 silc_server_rekey_final.
5115 * Removed Tunneled flag from the protocol. Updated the code
5116 and the specifications.
5118 * Adde `pfs' field to the SilcIDListData to indicate whether
5119 the PFS is to be performed in the re-key. Affected file is
5122 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5125 int64 of at least the xintXX size. If void * is less that 4
5126 bytes uint32 * will be used. Defined bool as boolean.
5128 * Changed _ALL_ unsigned long and unsigned int to uint32,
5129 unsgined short to uint16 in the source tree.
5131 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5132 not handle clients that has entry->data.registered == FALSE.
5133 They are not in the network anymore. Affected file is
5136 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Implemented the sending of the SERVER_SIGNOFF notify in the
5139 server. Affected file is silcd/server.c.
5141 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5142 Added also silc_notify_payload_encode_args into the
5143 lib/silccore/silcnotify.[ch].
5145 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5146 Affected file silcd/packet_receive.c.
5148 * Implemented the SERVER_SIGNOFF notify handling in the client
5149 library. Affected file lib/silcclient/client_notify.c. Also,
5150 implemnted the printing of the SERVER_SIGNOFF info to the
5151 application. Affected file silc/client_ops.c.
5153 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5154 if the deleting was successful. Affected file silcd/idlist.[ch].
5156 * Added support for public key authentication in the connection
5157 authentication protocol in the client library. Affected file
5158 lib/silcclient/protocol.c.
5160 * Changed the server's silc_idlist_get_clients_by_* interface
5161 to support already allocated array so that new entries may be
5162 added to pre-allocated array. Affected file silcd/idlist.[ch].
5163 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5164 and command replies.
5166 * All command reply functions in the server now calls the
5167 pending command callback even if error occured. This way the
5168 error will be delivered to the client as well. Affected files
5169 silcd/command.c and silcd/command_reply.c.
5171 * Fixed INFO command to return local server's info if no server
5172 was provided. Affected file lib/silcclient/command.c.
5174 * Removed RESTART command for good. Updated the code and the
5177 * Rewrote parts of the task system. It is a bit simpler now.
5178 Removed unsued task priorities. The affected files are
5179 lib/silcutil/silctask.[ch].
5181 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Moved the USERS printing from the library to the application.
5184 Affected files lib/silcclient/command.c and silc/client_ops.c.
5186 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Added channel key re-key support. The re-key is perfomed
5191 only by the router and is done once in an hour. Added `rekey'
5192 field to the SilcChannelEntry in the server. Affected files
5193 silcd/server.c and silcd/idlist.h.
5195 * Added silc_task_unregister_by_context into the file
5196 lib/silcutil/silctask.[ch].
5198 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Added SILC_UMODE_GONE mode to indicate when the client is not
5201 present in the SILC network. Added also support to the local
5202 command AWAY that will set this mode. Added support of showing
5203 "xxx is gone" in WHOIS command. The USERS command shows the
5204 gone status as well.
5206 * Fixed setting server and router operator privileges in the
5207 server's UMODE command. Affected file silcd/command.c.
5209 * Merged the SKE KE1 and KE2 payloads into one payload. The
5210 new KE payload is equivalent to the old KE2 payload.
5212 Cleaned up the SKE Start Payload parsing. It now uses the
5213 simple buffer unformatting to do the parsing. A lot faster
5216 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5217 to the SKE that is used to indicate whether both of the SKE
5218 parties should perform authentication. By default only the
5219 responder performs authentication. By setting this flag also
5220 the initiator must do authentication. By default it is unset
5221 since in normal SKE case, client to server connection, only
5222 the responder should do authentication. When doing SKE between
5223 two clients both should perform authentication. Updated the
5224 code and the protocol specs.
5226 * A little fix to IDENTIFY command in the server. Search the
5227 client first by hash not nickname. Affected file is
5230 * Fixed the silc_client_close_connection to support closing
5231 the client to client connections wihtout deleting too much
5232 data. Affected file lib/silcclient/client.c.
5234 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5235 are received if protocol used to be active but is not anymore
5236 the application would crash due to NULL pointer dereference.
5237 Affected files silcd/server.c and lib/silcclient/client.c.
5239 * Added `hash' field to the SilcClientConnection to include
5240 the hash function negotiated in the SKE protocol.
5242 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5243 to set the channel founder authentication data. A client can
5244 claim the founder rights later by providing the authentication
5245 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5246 This way the channel founder can regain the channel founder
5247 privileges even it is left the channel. This works only on
5248 local server and the client must be connected to the same
5249 server to be able to regain the founder rights. Updated the
5250 protocol specs accordingly.
5252 Added support to the CMODE command in the client to set the
5253 founder auth data. Read the README to see how to set it.
5255 Added support to the CUMODE command to claim the founder
5256 rights. Read the README to see how to do it.
5258 Added support for the founder authentication to the Channel
5259 Entry in the server. Affected file silcd/idlist.h.
5261 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5262 server's CMODE command. Affected file silcd/command.c.
5264 * Added the following new functions into lib/silccore/silcauth.[ch]:
5265 silc_auth_get_method and silc_auth_get_data.
5267 * The server now saves the remote hosts public key to the
5268 SilcIDListData pointer. Affected file silcd/protocol.c.
5270 * The normal server now does not remove the channel entry from
5271 the cache if the founder authentication data is set. It used
5272 to remove it if the founder was the last one on the channel on
5273 the server and left the channel. The auth data is saved and
5274 if the channel is re-joined later the old entry is used with
5275 the old auth data. Affected files silcd/command_reply.c and
5278 * Removed the `pkcs' field from the SilcIDListData structure
5279 in the server; it is not used. Affected file silcd/idlist.h.
5281 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Fixed packet processing on slow links. Partial packets were
5284 never re-processed because the incoming data buffer was cleared
5285 by the application. Application must not directly clear the
5286 sock->inbuf, the packet processing routines handle it. Fixed
5287 this in client library and in server.
5289 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Fixed the WHOIS and IDENTIFY send reply function to really
5292 check whether to send list or just one entry. Affected file
5295 * Cleaned up the LEAVE command's channel key distribution. The
5296 affected file silcd/command.c.
5298 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5299 can enforce the channel mode as well. In that case the ID
5300 includes the ID of the server. The code now enforces the
5301 mode change if the router have different mode than the server.
5303 * The notify client operation with CMODE_CHANGE notify can now
5304 return NULL client_entry pointer if the CMODE was not changed
5305 by client. Application must check for this.
5307 * Added <Server ID> argument to INFO command to support server
5308 info fetching by Server ID.
5310 * Added silc_server_announce_get_channel_users to get assembled
5311 packets of channel users of the specified channel. Affected
5312 file silcd/server.[ch].
5314 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5315 was freed underneath the ID Cache.
5317 * Re-announce clients when the server received CHANNEL_CHANGE
5318 notify from the router. Affected file silcd/packet_send.c.
5320 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5323 crashed since it did not handle the fact that there is no cipher
5324 called "3" and didn't check the error condition. Now fixed.
5326 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5327 flag. It can be used to send message requests.
5329 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Implemented the RESTART command in the client.
5333 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5334 notice type messages. Added notice printing to the user
5337 * The channel keys are not re-generated if the channel's mode
5338 is PRIVKEY, ie private key on the channel exists. Affected
5339 files silcd/server.c and silcd/command.c.
5341 * Fixed a little bug in channel message delivery when channel
5342 private keys are set in the server. Affected file is
5343 silcd/packet_send.c.
5345 * Changed the setting on channel->on_channel = TRUE from the
5346 silc_client_save_channel_key to the JOIN command reply. The
5347 key payload is not received if the private channel key is set.
5348 Affected file lib/silcclient/command_reply.c and the
5349 lib/silcclient/client_channel.c.
5351 * When the CMODE_CHANGE notify is sent and the channel private
5352 key mode is removed the channel key must be re-generated in
5353 other cells as well. Added this support for the router in the
5354 silcd/packet_receive.c.
5356 * Added new local command NOTICE to send notice message on
5357 channel. Affected file silc/local_command.[ch].
5359 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Added new local command ME to the client. It is used to send
5362 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5363 some action. Affected file silc/local_command.[ch].
5365 * Changed channel_message and private_message client operations
5366 to deliver the message flags to the application. Added also
5367 the `flags' arguments to the silc_client_send_channel_message
5368 and silc_client_send_private_message functions. Affected file
5371 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Redefined the Private Message Payload to support private message
5374 keys and to support the new private message flags. Updated
5375 the protocol specs. Flags makes it possible to have for example
5376 CTCP style messages.
5378 * Added new type SilcPrivateMessagePayload and defined an API
5379 for it in the lib/silcclient/silcprivate.[ch].
5381 * Tested private message private keys successfully. Tested the
5382 private message key set, unset and list commands with the new
5385 * Redefined the Channel Message Payload to include the channel
5386 message flags (equal with private message flags) to support
5387 for example CTCP style messages.
5389 * Defined some of the message (for channel and private message)
5390 flags. Updated the protocol specs and added the flags to the
5391 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5393 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Added SilcKeyAgreementStatus type to the key agreement routines
5396 to indicate the current status and error if one occured.
5397 The status types are defined in the lib/silcclient/silcapi.h.
5399 * Added new local command KEY that is used to set and unset private
5400 keys for channels, set and unset private keys for private messages
5401 with remote clients and to send key agreement requests and
5402 negotiate the key agreement protocol with remote client. The
5403 key agreement is supported only to negotiate private message keys,
5404 it currently cannot be used to negotiate private keys for channels,
5405 as it is not convenient for that purpose.
5407 * Fixed a minor pending callback setting bug in the function
5408 silc_client_get_client_by_id_resolve, now the function works.
5409 Affected file lib/silcclient/idlist.c.
5411 * Added function silc_net_get_local_port to get local bound
5412 port by socket. Added to lib/silcutil/silcnet.[ch].
5414 * Added `sockets' and `sockets_count' fields to the SilcClient
5415 object. They hold the sockets of the listenning sockets in
5416 the client. Listenning sockets may be for example the key
5417 agreement server. Affected file lib/silcclient/client.[ch].
5418 Added functions the silc_client_add_socket and the
5419 silc_client_del_socket. They are exported to the application
5422 * Added ~./silc/clientkeys to support other client's public keys.
5424 * Renamed verify_server_key client operation to verify_public_key
5425 and added one argument to indicate the type of the connection
5426 (server, client etc.).
5428 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Added silc_server_connection_auth_request to handle the
5431 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5432 silcd/packet_receive.[ch].
5434 * Added silc_server_send_connection_auth_request into the
5435 silcd/packet_send.c to send the connection auth request packet.
5437 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5440 * Fixed the public key authentication in responder side in the
5441 server. The `auth_data' pointer includes the SilcPublicKey
5442 not the path to the public key. Affected file silcd/protocol.c.
5444 * Implemented the public key authentication in the initiator side
5445 in the server. Affected file silcd/protocol.c.
5447 * Removed the [RedirectClient] config section from the server
5448 configuration. Is not needed and I don't want to implement it.
5450 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Cleaned up the CMODE command in the server. It now works
5453 correctly and supports all the modes defined in the protocol.
5454 Affected file is silcd/command.c.
5456 * Added `hmac_name' field to the SilcChannelEntry in the server
5457 to hold the default HMAC of the channel. It can be set when
5458 creating the channel (with JOIN command). Affected files
5461 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5462 type to indicate the change of the current cipher and hmac
5463 on the channel. Client can safely ignore the <cipher> argument
5464 (if it chooses to do so) since the CHANNEL_KEY packet will
5465 force the channel key change anyway. The <hmac> argument is
5466 important since the client is responsible of setting the new
5467 HMAC and the hmac key into use.
5469 * Fixed the CMODE command in the client library as well.
5471 * Tested CMODE command in router environment successfully.
5473 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Show the version of the remote client (or server) when connecting
5476 to the server. It is logged to the log file. Affected file
5477 is silcd/protocol.c.
5479 * Fixed the KILLED notify handling in the client library. The
5480 client must be removed from all channels when receiving the
5483 Also, do not remove the client entry when giving the KILL
5484 command but when the KILLED notify is received.
5486 * Removed silc_idlist_find_client_by_nickname from the server.
5487 Not needed anymore. Affected files silcd/idlist.[ch].
5489 * Implemented the CHANNEL_CHANGE notify type handling to the
5490 server. Affected file silcd/server.c.
5494 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Added silc_server_send_notify_invite to send the INVITE
5497 notify between routers.
5499 * Implemented the INVITE command correctly to the server.
5501 * Implemented the INVITE notify type handling in the server.
5503 * Implemented the INVITE command to the client library and on the
5506 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Added function silc_server_get_client_resolve to find the
5509 client entry by ID from all ID lists and then resolve it
5510 (using WHOIS) if it cannot be found. Affected file is
5513 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Implemented the BAN command to the client library.
5517 * The JOIN command in the server now checks the invite list
5520 * Changed the silc_command_reply_payload_encode_va and the
5521 silc_command_payload_encode_va to support that if argument is
5522 NULL it ignores and checks the next argument. Affected file
5523 lib/silccore/silccommand.c.
5525 * Added silc_server_send_notify_ban to send the BAN notify
5526 type between routers.
5528 * Chaned the silc_notify_payload_encode to support that if
5529 argument is NULL it ignores and checks the next argument.
5530 Affected file lib/silccore/silcnotify.c.
5532 * Tested ban lists in router environment successfully.
5534 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Implemented BAN command to the server, in silcd/command.[ch].
5538 * Removed the BAN and INVITE_LIST modes from the CMODE command
5541 * Added function silc_string_match to regex match two strings.
5542 Affected files lib/silcutil/silcutil.[ch].
5544 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Redefined parts of the SilcChannelEntry in the server to support
5547 the new ban and invite lists.
5549 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Redefined the INVITE command. The same command can be used to
5552 invite individuals to the channel but also to manage the invite
5553 list of the channel (to add to and remove from the invite list).
5554 Updated the protocol specs.
5556 * Added new command SILC_COMMAND_BAN that can be used to manage
5557 the ban list of the channel. Updated the protocol specs.
5559 * Removed the channel modes: the SILC_CMODE_BAN and the
5560 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5561 in the CMODE command. The equivalent features are now available
5562 using INVITE and BAN commands. Updated the protocol specs.
5564 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5565 in the network about change in the current ban list. The notify
5566 type is not used by the client.
5568 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5569 support the invite lists.
5571 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Added new function silc_string_regexify that converts string
5574 including wildcard characters into regex string that can
5575 be used by the GNU regex library. Added into the file
5576 lib/silcutil/silcutil.[ch].
5578 Added silc_string_regex_combine to combine to regex strings
5579 into one so that they can be used as one regex string by
5580 the GNU regex library. Added into the file
5581 lib/silcutil/silcutil.[ch].
5583 Added silc_string_regex_match to match two strings. It returns
5584 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5586 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Imported GNU regex to the soruce tree into lib/contrib.
5589 Fixed some compiler warning from the regex.c.
5591 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Fixed MOTD command in the server to work in router environment.
5595 * Fixed the MOTD command in the client library to support
5596 the server argument in the command.
5598 * Added `nickname_len' argument to the silc_idlist_add_client
5599 in the server, as the `nickname' argument may be binary data
5602 * Added silc_idlist_get_channels to return all channels from
5605 * Implemented LIST command to the server. Affected file is
5608 * Implemented the LIST command to the client library and on the
5611 * Added [<user count>] argument to the LIST command reply.
5612 With private channels the user count is not shown.
5614 * Updated TODO and README.
5616 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * The client entry's data.registered must be TRUE even with
5619 global client entry on global client list. The data.registered
5620 is used to check whether the client is anymore in the network,
5621 for example with WHOWAS command so it must be valid.
5623 * Fixed the WHOWAS command in the server. It now actually works
5624 in router environment. Added function into silcd/command_reply.c
5625 silc_server_command_reply_whowas_save.
5627 * Added silc_idlist_purge function to the silcd/idlist.c
5628 to periodically purge the ID Cache.
5630 * Fixed INFO command in the server. It works now in router
5631 environment. Added <server name> argument to the INFO command
5632 reply. Updated the protocol specs.
5634 * Fixed minor bug in silc_idcache_purge to not purge if the
5635 expire value is zero.
5637 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5638 they were buggy because of the WHOWAS information.
5640 * Fixed local command MSG to handle the async resolving of
5641 the remote client properly. It used to fail the first MSG.
5642 Affected file silc/local_command.c.
5644 * Added `data_len' field to SilcIDCache context.
5646 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Update TODO. Todo in commands in the server.
5650 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5653 used by routers as broadcast packet to inform other routers
5654 about the changed user mode.
5656 Implemented the notify handling in the server. Affected file is
5657 silcd/packet_receive.c. Added the function
5658 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5660 * Added new generic Channel Payload and deprecated the New Channel
5661 Payload. The New Channel Payload is now the generic Channel
5664 * Added new argument `mode' to the silc_server_send_new_channel
5665 as it is required in the Channel Payload now.
5667 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5668 and created a new and real SilChannelPayload to represent the
5669 new generic Channel Payload. Implemented the encode/decode
5670 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5672 * Added silc_server_get_client_channel_list to return the list
5673 of channels the client has joined for WHOIS command reply.
5674 Affected file silcd/server.[ch].
5676 * Implemented the channel list sending in the WHOIS command reply
5677 in server and in the client.
5679 Implemented the channel list displaying on the user interface
5680 as well. Affected file silc/client_ops.c.
5682 * Added silc_channel_payload_parse_list to parse list of Channel
5683 Payloads. It returns SilcDList list of SilcChannelPayloads.
5684 Client for example can use this function to parse the list of
5685 channels it receives in the WHOIS command reply. The caller
5686 must free the list by calling silc_channel_payload_list_free.
5687 Affected files lib/silccore/silcchannel.[ch].
5689 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Added one new argument <user mode> to the WHOIS command reply
5692 to return the mode of the user in SILC. Updated the protocol
5695 Implemented it to the server and client.
5697 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Fixed the mode printing on the user interface on joining.
5700 Affected file silc/client_ops.c.
5702 * Implemented the UMODE command and user modes in general to the
5703 client library and to the user interface.
5705 * Implemented the UMODE command to the server.
5707 * The server now sends UNKNOWN_COMMAND error status if client sends
5708 unknown command. Affected file silcd/command.c.
5710 * All server commands now handle the command identifier the right
5711 way when sending the command reply to the client. The client can
5712 use to identify the command replies with the identifier.
5714 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added silc_server_get_client_route to resolve the route to
5717 the client indicated by the client ID. Affected file is
5720 * Added silc_server_relay_packet as general function to relay
5721 packet to arbitrary destination. This deprecates functions
5722 like _send_private_message_key, _relay_notify etc. Affected
5723 file is silcd/packet_send.[ch].
5725 Removed silc_server_send_key_agreement,
5726 silc_server_send_private_message_key and
5727 silc_server_packet_relay_notify functions from the file
5728 silcd/packet_send.[ch].
5732 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5733 server. Affected file silcd/packet_receive.[ch].
5735 * Implemented the KILL command to the client. Implemented the
5736 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5737 Affected files lib/silcclient/command[_reply].c and
5738 lib/silcclient/client_notify.c. Implemented the KILL notify
5739 printing in the user inteface.
5741 * Fixed a lot silc_parse_nick memory leaks from the client
5742 library in the file lib/silcclient/command.c.
5744 * Changed the silc_server_send_notify_on_channels's `sender'
5745 argument from SilcSocketConnection to SilcClientEntry to
5746 check the sender as entry and not as connection object and not
5747 to send to the client provided as argument. The affected file
5748 is silcd/packet_send.[ch].
5750 * The notify packets that are destined directly to the client used
5751 to not to be processed by the server. Now changed that and the
5752 server processes all notify packets. After relaying the packet
5753 to the client the notify packet is processed in the server.
5755 * The silc_server_free_client_data now checks whether there is
5756 pending outgoing traffic for the client and purges the data to
5757 the network before removing the client entry.
5759 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5762 an client is killed from the SILC Network. Updated the protocol
5765 Added new function silc_server_send_notify_killed to the
5766 silcd/packet_send.[ch].
5768 * Added function silc_server_packet_relay_notify to relay notify
5769 packets that are destined directly to a client. In this case
5770 the server does not process the notify packets but merely relays
5771 it to the client. Affected file silcd/packet_send.[ch].
5773 Added also silc_server_packet_process_relay_notify to check
5774 whereto relay the notify. Affected file is
5775 silcd/packet_receive.[ch].
5777 * Implemented the KILL command to the server.
5781 * Added the backup schema desgined last fall to the protocol
5782 specs for everyone to see. The specification is in the
5783 *-spec-xx.txt draft and the packet type definitions for the
5784 backup routers is in *-pp-xx.txt draft. Thusly, added also
5785 new packet type SILC_PACKET_CELL_ROUTERS.
5787 * A big security problem in the implementation discovered. The
5788 signoff of an client did not cause new channel key generation
5789 which it of course should've done. The channel keys must be
5790 always re-generated when client leaves (or signoffs) the channel.
5791 The silc_server_remove_from_channels funtion now handles
5792 the channel key re-generation.
5794 * Added `sender' argument to the silc_server_send_notify_on_channels
5795 to not to send the client provided as argument. Affected file
5796 silcd/packet_send.[ch].
5798 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Implemented OPER and SILCOPER commands into the server and
5803 * Added silc_auth_verify and silc_auth_verify_data to verify
5804 the authentication directly from the authentication payload.
5805 It supports verifying both passphrase and public key based
5806 authentication. Affected file lib/silccore/silcauth.[ch].
5808 * Added `hash' field to the SilcIDListData structure. It is the
5809 hash negotiated in the SKE protocol. Affected file is
5812 * Slight redesigning of the SilcAuthPayload handling routines.
5813 Do not send SilcPKCS but SilcPublicKey as argument.
5815 * Implemented the public key authentication support to the
5816 serverconfig. The public key is loaded from the provided path
5817 and saved as authentication data to void * pointer. Thus,
5818 changed the unsigned char *auth_data to void *auth_data;
5820 * Fixed SHUTDOWN command to send the reply before the server
5821 is shutdown. :) Affected file silcd/command.c.
5823 * Fixed fatal bug in CONNECT command. The hostname was invalid
5824 memory and server crashed. Affected file silcd/command.c.
5826 * Fixed fatal bug in CLOSE command. The server_entry became
5827 invalid but was referenced later in the command. Affected file
5830 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Fixed fatal bug in failure packet handling. Server ignored
5833 the failure and thus crashed when it came.
5837 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5840 that the command may be executed only once in (about) 2 seconds.
5841 The old SILC_CF_LAG flag is same but allows command bursts up
5842 to five before limiting.
5844 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5845 server code. Various commands now includes the CF_LAG_STRICT
5846 flag to disallow any kind of miss-use of the command.
5848 * Fixed the silc_buffer_unformat to not to allocate any data
5849 if the length of the data is zero. It used to allocate the
5850 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5852 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Changed the format of AdminConnection configuration section
5855 in the server. Added username of the admin to the format.
5856 Affected files silcd/serverconfig.[ch].
5858 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5859 to return admin configuration data by host, username and/or
5862 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Implemented WHOWAS command to the server. Added the functions:
5866 silc_server_command_whowas_parse,
5867 silc_server_command_whowas_send_reply,
5868 silc_server_command_whowas_from_client and
5869 silc_server_command_whowas_from_server
5871 * Added <Client ID> argument to the WHOWAS command reply. Updated
5872 the protocol specs accordingly.
5874 * Implemented WHOWAS command and command_reply to the client
5877 Implemented the WHOWAS printing on the user interface.
5879 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Added new argument to the WHOWAS command reply, the real name.
5882 It is an optional argument. Updated the protocol specs.
5884 * Added SilcIDCacheDestructor callback that is registered when
5885 the SilcIDCache is allocated. The callback is called when
5886 an cache entry in the ID Cache expires, or is purged from the
5887 cache. Added into lib/silccore/idcache.[ch].
5889 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5890 to destruct the client entries when the cache entry expires.
5891 Other ID Cache's in server and in the client library ignores
5894 * If the ID Cache entry's `expire' field is zero then the entry
5895 never expires. Added boolean `expire' argument to the
5896 silc_idcache_add function in the lib/silccore/idcache.[ch].
5897 If it is TRUE the default expiry value is used.
5899 * Added silc_server_free_client_data_timeout that is registered
5900 when client disconnects. By default for 5 minutes we preserve
5901 the client entry for history - for WHOWAS command.
5903 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Added support to the server to enforce that commands are not
5906 executed more than once in 2 seconds. If server receives
5907 commands from client more frequently, timeout is registered
5908 to process the commands. Affected file silcd/command.c.
5909 Added new function silc_server_command_process_timeout.
5911 * Changed NICK_NOTIFY handling in client library to check that
5912 if the client's nickname was changed, so there is no need to
5913 resolve anything from the server.
5915 * Removed error printing from the WHOIS and IDENTIFY commands.
5916 If error occurs then it is ignored silently in the client library.
5917 The application, however, may map the received error to
5918 human readable error string. The application currently maps
5919 the NO_SUCH_NICKNAME error to string.
5921 * Made the command status message public to the application. Moved
5922 them from lib/silcclient/command_reply.c to
5923 lib/silcclient/command_reply.h. The application can map the
5924 received command status to the string with the
5925 silc_client_command_status_message function.
5927 * Added check to the server to check that client's ID is same
5928 as the Source ID in the packet the client sent. They must
5931 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Added dist-bzip hook to the Makefile.am to make bzip2
5934 compressed distributions.
5936 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Server now enforces the maximum length for the nickname and
5939 the channel as protocol specification dictates. 128 bytes for
5940 nickname and 256 bytes for channel name.
5942 * Moved the WHOIS printing to the application. The client libary
5943 does not print out the WHOIS information anymore, the application
5944 must do it. Renamed silc_client_command_reply_whois_print to
5945 the silc_client_command_reply_whois_save.
5947 The client's idle time is also sent to the application now, and
5948 the idle is shown on screen.
5950 * Added silc_client_command_reply_identify_save to save the
5951 received IDENTIFY entries.
5953 * Do not check for channel private keys in message sending and
5954 reception if the channel does not have the PRIVKEY mode set.
5955 Affected file lib/silclient/client_channel.c.
5957 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5960 just surfaced after chaning the JOIN procedure.
5962 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Added silc_client_get_clients_by_list to get client entries
5965 from Client ID list, that is returned for example by JOIN
5966 and USERS command replies. The application should use this
5967 function for example when JOIN command reply is received to
5968 resolve the clients already on the channel (library does not
5969 do that anymore as USERS command reply is not used in the JOIN
5970 procedure anymore). Affected files lib/silcclient/silcapi.h and
5971 lib/silcclient/idlist.c.
5973 * JOIN command reply and USERS command reply returns now SilcBuffer
5974 pointers instead of unsigned char pointers when returning
5975 the client list and mode list.
5977 * Added <Client ID> argument to the JOIN command reply, mainly
5978 for the server to identify for which client the command was
5979 originally sent. Updated protocol specs accordingly.
5981 * Added SilcDlist private_key pointer to the SilcChannelEntry
5982 in the client to support the channel private keys. Affected
5983 file is lib/silcclient/idlist.h.
5985 * Added SilcChannelPrivateKey argument to the function
5986 silc_client_send_channel_message so that application can choose
5987 to use specific private ke if it wants to. If it is not provided,
5988 the normal channel key is used, unless private keys are set.
5989 In this case the first (key that was added first) is used
5990 as the encryption key.
5992 * Implemented the support for channel private key handling.
5993 Implemented the following functions:
5995 silc_client_add_channel_private_key,
5996 silc_client_del_channel_private_keys,
5997 silc_client_del_channel_private_key,
5998 silc_client_list_channel_private_keys and
5999 silc_client_free_channel_private_keys
6001 Affected file lib/silcclient/client_channel.c.
6003 * Added the support for the private keys in the channel message
6004 sending and encryption and in the message reception and
6005 decryption. Affected funtions are
6006 silc_client_send_channel_message and silc_client_channel_message.
6008 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Added SKE's key verify callback to the client library's
6011 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6013 * Removed the statement that server (or router) must send USERS
6014 command reply when joining to the channel so that the client
6015 knows who are on the channel. Instead, the client list and
6016 client's mode list is now sent in the JOIN command reply to the
6017 client who joined channel. This is better solution.
6019 * Added function silc_server_get_users_on_channel and function
6020 silc_server_save_users_on_channel to the silcd/server.[ch].
6022 * Removed function silc_server_command_send_users from the
6025 * Do not show topic on the client library anymore. The topic is
6026 sent in the command reply notify to the application and the
6027 application must show the topic now.
6029 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Added client searching by nickname hash into the IDENTIFY and
6032 WHOIS commands in the server as they were clearly missing from
6033 them. Affected file is silcd/command.c.
6035 * Fixed a bug in private message receiving in the client library.
6036 The remote ID was freed and it wasn't supposed, now it is
6039 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Minor fix to the channel payload; allocate the data area, as it
6042 needs to be of specific length.
6044 * If the key agreement port is zero then the operating
6045 system will define the bound port. Affected files are
6046 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6048 * Added new function silc_channel_payload_decrypt into the file
6049 lib/silccore/silcchannel.[ch].
6051 * Moved the channel message etc, check from silc_packet_decrypt
6052 to applications. The library calls now a generic
6053 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6054 when the packet is either normal or special. This was done to
6055 allow more wide range of checking that was not allowed when
6056 the code was in library. Now applications can do virtually any
6057 checks to the packet and return to the library the decision how
6058 the packet should be processed. Affected files are
6059 lib/silccore/silcpacket.[ch].
6061 Added silc_server_packet_decrypt_check to the server and
6062 silc_client_packet_decrypt_check to the client library.
6064 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6065 to send with specified source and destination information.
6067 * Channel message delivery between routers was broken after the
6068 channel key distribution was fixed earlier. The channel key
6069 was used be to distributed to other routers as well which is not
6070 allowed by the protocol. Now this is fixed and channel keys
6071 really are cell specific and the channel message delivery between
6072 routers comply with the protocol specification.
6074 * Fixed various commands in server to check also the global list
6075 for the channel entry and not just the local list. The affected
6076 file silcd/command.c.
6078 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added assert()s to buffer formatting and unformatting routines
6081 to assert (if --enable-debug) when error occurs. Affected
6082 file: lib/silcutil/silcbuffmt.c.
6084 * Changed to auto-reconnect to check whether the remote host is
6085 router and register the re-connect timeout if it is. It used
6086 to check that whether we are normal server, but router must do
6087 auto-reconnect with another router as well. Affected file
6090 * Removed the [<key len>] option from CMODE command as the cipher
6091 name decides the key length, nowadays. See the defined ciphers
6092 from the protocol specification.
6094 * Added [<hmac>] option to the CMODE command to define the HMAC
6095 for the channel. Added SILC_CMODE_HMAC channel mode.
6097 * Added [<hmac>] option for the JOIN command so that user can
6098 select which HMAC is used to compute the MACs of the channel
6101 * Added Hmac field to the Channel Message Payload. The integrity
6102 of plaintext channel messages are now protected by computing
6103 MAC of the message and attaching the MAC to the payload. The
6104 MAC is encrypted. Now, it is clear that this causes some
6105 overhead to the size of the packet but rationale for this is that
6106 now the receiver can verify whether the channel message decrypted
6107 correctly and also when private keys are set for the channel the
6108 receiver can decrypt the packet with several keys and check from
6109 the MAC which key decrypted the message correctly.
6111 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6112 lib/silccrypt/silccipher.[ch].
6114 * Added silc_hash_len to return the digest length into the
6115 lib/silcrypt/silchash.[ch].
6117 * Rewrote parts of Silc Channel Payload interface in the
6118 lib/silccore/silcchannel.[ch]. The encode function now also
6119 encrypts the packet and parse function decrypts it.
6121 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Fixed a minor formatting bug in the SKE's key material processing.
6124 It actually might have processed the keys wrong way resulting
6127 * Redefined the mandatory HMAC algorithms and added new algorithms.
6128 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6129 and hmac-md5 truncated to 96 bits. The mandatory is now
6130 hmac-sha1-96. Rest are optional (including the one that used
6131 to be mandatory). Rationale for this is that the truncated HMAC
6132 length is sufficient from security point of view and can actually
6133 make the attack against the HMAC harder. Also, the truncated
6134 HMAC causes less overhead to the packets. See the RFC2104 for
6137 * Added new [hmac] configuration section. The SKE used to use
6138 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6139 is of course wrong. The official names that must be proposed in
6140 the SKE are the ones defined in the protocol specification
6141 (hmac-sha1-96 for example). The user can configure any hmac
6142 using any hash function configured in the [hash] section. At
6143 least, the mandatory must be configured.
6145 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6147 * Added HMAC list to the SKE proposal list. It has now both
6148 hash algorithm list and HMAC list. This makes the protocol
6149 incompatible with previous versions. The SKE now seems to work
6150 the way it is supposed to work, for the first time actually.
6152 * Defined plain Hash algorithms to the protocol specification.
6155 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Implemented support for key agreement packets into the server.
6158 Added functions silc_server_key_agreement and
6159 silc_server_send_key_agreement. Other than these functions,
6160 server has nothing to do with this packet.
6162 * Added support for private message key packets into the server.
6163 Added functions silc_server_private_message_key and
6164 silc_server_send_private_message_key.
6168 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6169 called in the protocol's final callback instead in the END
6170 protocol state. This makes a little more sense and in the same
6171 time in client we can use the same protocol routines for normal
6172 key exchange and to key agreement packet handling as well.
6174 * Added to both client's and server's KE protocol context the
6175 SilcSKEKeyMaterial pointer to save the key material. We will
6176 bring the key material to the protocol's final callback by doing
6177 this. The final callback must free the key material.
6179 * Added SKE's packet_send callback into client's KE protocol
6180 context so that the caller can choose what packet sending function
6181 is used. This way we can use different packet sending when
6182 doing normal SKE when doing key agreement packet handling (in
6183 the key agreement packet handling we do not want to encrypt
6186 * Implemented the responder side of the key agreement routines
6187 in the client. The client can now bind to specified port and
6188 accept incoming key negotiation. The key material is passed
6189 to the application after the protocol is over.
6191 * Implemented the processing of incoming Key Agreement packet
6192 in the client. Added function silc_client_key_agreement to
6195 * Implemented the intiator side of the key agreement routines
6196 in the client. The client can now initiate key agreement with
6197 another remote client. The key material is passed to the
6198 application after the protocol is over.
6200 * Created client_keyagr.c to include all the key agreement
6203 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6204 SILC_TASK_CALLBACK except that it is not static.
6206 * Created client_notify.c and moved the Notify packet handling
6207 from the client.[ch] into that file.
6209 * Created client_prvmsg.c and moved all private message and
6210 private message key routines from the client.[ch] into that file.
6212 * Create client_channel.c and moved all channel message and
6213 channel private key routines from the client.[ch] into that file.
6215 * Changed silc_client_get_client_by_id_resolve to resolve with
6216 WHOIS command instead of IDENTIFY command, in the file
6217 lib/silclient/idlist.c.
6219 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Implemented the SKE's responder side to the Client library.
6223 * When FAILURE is received to the protocol do not trust it
6224 blindly. Register a timeout to wait whether the remote closes
6225 the connection as it should do it, only after that process the
6226 actual failure. This was changed to both client and server.
6228 * Added client_internal.h to include some of the structures
6229 there instead of client.h in lib/silcclient/.
6231 * Added function silc_task_unregister_by_callback to unregister
6232 timeouts by the callback function.
6234 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Some "Incomplete WHOIS info" errors has been appearing on the
6237 log files. Took away the entry->userinfo check from WHOIS
6238 reply sending. The entry->userinfo is now " " if client did not
6239 provide one. I thought this was fixed earlier but something
6240 is wrong still. Let's see if the error still appears.
6242 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Fixed a minor bug in the login when the channel key is
6245 re-generated in the server. It used to generate the key in
6246 wrong order and thus caused problems in the channel traffic.
6248 * Fixed a minor bug in channel key distsribution after
6249 KICK command. The key was not sent to the router even though
6252 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Added silc_ske_process_key_material_data as generic routine
6255 to process any key material as the SILC protocol dictates. The
6256 function is used by the actual SKE library but can be used by
6257 applications as well. This relates to the private message keys
6258 and the channel private keys since they must be processed the
6259 same way the normal SILC session keys. The protocol dictates
6260 this. Affected files: lib/silcske/silcske.[ch].
6262 Added also silc_ske_free_key_material to free the
6263 SilcSKEKeyMaterial structure.
6265 * Defined silc_cipher_set_key function to set the key for
6266 cipher without using the object's method function. The affected
6267 files: lib/silccrypt/silccipher.[ch].
6269 * Implemented silc silc_client_add_private_message_key,
6270 silc_client_add_private_message_key_ske,
6271 silc_client_del_private_message_key,
6272 silc_client_list_private_message_keys and
6273 silc_client_free_private_message_keys functions in the
6276 Added functions silc_client_send_private_message_key to send
6277 the Private Message Key payload and silc_client_private_message_key
6278 to handle incoming Private Message Key payload.
6280 * Added Cipher field to the Private Message Key payload to set
6281 the cipher to be used. If ignored, the default cipher defined
6282 in the SILC protocol (aes-256-cbc) is used.
6284 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Removed lib/silcclient/ops.h file.
6288 Redefined parts of the SILC Client Library API. Created new
6289 file silcapi.h that deprecates the ops.h file and defines the
6290 published Client Library API. Defined also private message key
6291 API and channel private key API into the file.
6293 This is the file that the application must include from the
6294 SILC Client Library. Other files need not be included by
6295 the application anymore.
6297 * Added new key_agreement client operation callback and also
6298 defined the Key Agreement library API for the application.
6300 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6303 is used by clients to request key negotiation between another
6304 client in the SILC network. If the negotiation is started it
6305 is performed using the SKE protocol. The result of the
6306 negotiation, the secret key material, can be used for example
6307 as private message key.
6309 Implemented the Key Agreement payload into the files
6310 lib/silccore/silauth.[ch].
6312 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Redefined ciphers for the SILC protocol. Added some new ciphers
6315 and defined the key lengths for the algorithms. Changed the
6316 code accordingly. The default key length is now 256 bits.
6318 * Fixed SKE key distribution function silc_ske_process_key_material
6319 when the key length is more than 128 bits. The default key
6320 length in SILC is now 256 bits.
6322 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6323 to indicate unsupported algorithm.
6325 * Renamed rijndael.c to aes.c and all functions as well.
6327 * Fixed a long standing channel key setting bug in client library.
6328 Weird that it has never surfaced before.
6330 * Fixed bug in channel deletion. If the entire channel is removed
6331 then it must also delete the references of the channel entry
6332 from the client's channel list as the client's channel entry and
6333 the channel's client entry share same memory.
6335 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Implemented CONNECT and SHUTDOWN commands in the client.
6339 * Implemented CLOSE command to the client.
6341 * Added the function silc_idlist_find_server_by_name into the
6342 files silcd/idlist.[ch].
6344 Added the function silc_idlist_find_server_by_conn into the
6345 files silcd/idlist.[ch].
6347 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * DIE command was renamed to SHUTDOWN. Updated the both code
6352 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6353 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6355 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6358 * Added function silc_server_create_connection function to create
6359 connection to remote router. My server implementation actually
6360 does not allow router to connect to normal server (it expects
6361 that normal server always initiates the connection to the router)
6362 so the CONNECT command is only good for connecting to another
6365 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6368 or some other client was kicked from the channel.
6370 Implemented the handling of the notify type to both client
6373 Implemented silc_server_send_notify_kicked to send the KICKED
6374 notify. It is used to send it to the server's primary router.
6376 * Implemented the KICK command into server and client.
6378 * Added `query' argument to the silc_idlist_get_client function
6379 to indicate whether to query the client from server or not if
6382 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6383 to indicate that the client is not channel founder.
6387 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Removed the rng context from SilcPacketContext structure and
6390 changed that the packet routine uses the Global RNG API.
6392 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Added support for quit message that client can "leave" on the
6395 channel when it quits the SILC. It is ditributed inside the
6396 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6398 Added silc_server_free_client_data that will take the
6399 signoff message as argument.
6401 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6403 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Updated parts of the protocol specification to keep it up
6408 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6411 payloads in one packet.
6413 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6414 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6415 use now the new List flag.
6417 * Also deprecated the following packet types: REPLACE_ID,
6418 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6420 * Added list support for Notify packet in server.
6422 * Added silc_server_send_notify_channel_change to send the
6423 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6424 the silc_server_send_replace_id.
6426 * Added silc_server_send_notify_nick_change to send the
6427 NICK_CHANGE notify type. Deprecates the function
6428 silc_server_send_replace_id.
6430 * Added silc_server_send_notify_join to send the JOIN notify type.
6431 Deprecates the function silc_server_send_new_channel_user.
6433 * Added silc_server_send_notify_leave to send LEAVE notify type.
6434 Deprecates the function silc_server_send_remove_channel_user.
6436 * Added silc_server_send_notify_cmode and
6437 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6438 types. Deprecates the silc_server_send_set_mode function.
6440 * Added SERVER_SIGNOFF notify type to indicate that server has
6441 quit. This means that all clients on the channel from that
6442 server will drop. This can be also used when netsplit happens.
6444 Deprecated REMOVE_ID packet type since it is not needed anymore
6447 Added silc_server_send_notify_server_signoff to send the
6448 SERVER_SIGNOFF notify type. Deprecates the function
6449 silc_server_send_remove_id.
6451 Added also silc_server_send_notify_signoff to send the
6452 SIGNOFF notify type.
6454 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6455 SILC protocol from this day on. Changed the protocol
6456 specification as well.
6458 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6459 notify type. It is used between routers to notify about
6460 topic changes on a channel.
6462 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6465 * Partly updated the protocol specification to comply with the
6466 changes now made. It is still though a bit outdated.
6468 * The JOIN notify type now takes one extra argument <Channel ID>.
6469 The packet used to be destined to the channel but now the
6470 JOIN type may be sent as list thus it is impossible to
6471 destine it to any specific channel. By adding this argument
6472 it is again possible.
6474 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added CREDITS file. The CHANGES and CREDITS file will appear
6477 in the distribution as well.
6479 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6482 types in the server's silcd/packet_receive.c.
6484 * Implemented CMODE and CUMODE to work in router environment.
6486 * Fixed minor encoding and decoding buglet from the
6487 lib/silccore/silcmode.c.
6489 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6492 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6494 * Changed all SilcConfigServer* and silc_config_server* to
6495 SilcServerConfig* and silc_server_config*, respectively.
6498 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Associated the ID (client or server ID) to the Authentication
6501 Payload to avoid any possibility of forging. Updated the
6502 protocol specification and the code accordingly.
6504 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * The RSA key length is now save to the RsaKey context in the
6507 key generation process in lib/silccrypt/rsa.c. The key length
6508 is now used to figure out the maximum size of the block allowed
6509 to be encrypted/signed.
6511 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6512 is equivalent to the silc_mp_mp2bin but does not allocate any
6515 * Changed silc_mp_mp2bin API to take length argument. If it is
6516 non-zero then the buffer is allocated that large. If zero, then
6517 the size is approximated using silc_mp_sizeinbase, which however
6520 * Created Global RNG API which is global RNG that application can
6521 initialize. After initializing, any routine anywhere in the
6522 code (including library) can use RNG without allocating a new
6523 RNG object. This was done to allow this sort of use of the
6524 RNG in code that has no chance to allocate RNG object. All
6525 applications currently allocate this and many routines in the
6526 library use this. Affected file lib/silccrypt/silcrng.[ch].
6528 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6529 it to use the Global RNG API.
6531 * Defined Authentication Payload into protocol specification that
6532 is used during SILC session to authenticate entities. It is
6533 used for example by client to authenticate itself to the server
6534 to obtain server operator privileges.
6536 Implemented this payload into the lib/silccore/silcauth.[ch].
6537 Implemented also routines for public key based authentication
6538 as the new protocol specification dictates.
6540 Moved definitions of different authentication methods from
6541 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6543 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6544 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6545 silc_pkcs_verify_with_hash functions into the file
6546 lib/silccrypt/silcpkcs.[ch].
6548 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * The client entry's userinfo pointer must be always valid.
6551 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6552 will fail since it requires the userinfo. Now, the userinfo
6553 is allocated as "" if actual userinfo does not exist. Actually,
6554 it must exist and it is totally Ok to drop client connections
6555 that does not announce the userinfo. However, we will make
6556 this workaround for now.
6558 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6559 to return the remote port by socket.
6561 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6563 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6564 SILC_SERVER_PENDING_EXEC and added an new macro
6565 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6566 data or when error occurs while processing the pending command.
6568 Added new argument `destructor' into silc_server_command_pending
6569 and to the SilcServerCommandPending object. This destructor is
6570 now called after calling the pending callback or if error occurs
6571 immediately. If error occurs the actual pending callback won't
6572 be called at all - only the destructor. The destructor may be
6573 NULL if destructor is not needed.
6575 All this applies for client library code as well. Similar
6576 changes were made there as well for the pending commands.
6578 In the client, the application must now allocate the
6579 SilcClientCommandContext with the silc_client_command_alloc
6582 * Added reference counter to the SilcServerCommandContext. Added
6583 function silc_server_command_alloc and silc_server_command_dup
6586 Same type of functions added to the client library for the same
6589 * Removed the cmd_ident from IDListData away since it is now
6590 global for all connections. It is the command identifier used
6591 in command sending and with pending commands. The affected file
6594 * Added reference counter to the SilcSocketConnection objecet to
6595 indicate the usage count of the object. The object won't be
6596 freed untill the reference counter hits zero. Currently only
6597 server uses this, and client ignores it. The client must be
6598 set to use this too later. The affected files are
6599 lib/silccore/silcsockconn.[ch]. Added also the function
6600 silc_socket_dup to increase the reference counter.
6602 This was mainly added because it is possible that the socket
6603 is removed underneath of pending command or other async
6604 operation. Now it won't be free'd and proper DISCONNECTING
6605 flags, etc. can be set to avoid sending data to connection that
6606 is not valid anymore.
6608 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6609 the connection. After that it sets SILC_SET_DISCONNECTED.
6610 It is, however, possible that the socket data is not still freed.
6611 The silc_server_packet_process now checks that data is not
6612 read or written to connection that is DISCONNECTED. The socket
6613 get's freed when the reference counter hits zero.
6615 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Changed the client operation API: channel_message operation's
6618 `sender' is now the client entry of the sender, not the nickname
6619 and the `channel' is the channel entry, not the channel name.
6621 In the private_message operation the `sender' is now also the
6622 client entry of the sender not the nickname.
6624 Affected file is lib/silcclient/ops.h and all applications
6625 using the client operations.
6627 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Moved the calling of ops->connect() from connect_to_server_final
6630 into receive_new_id functin since that is the point when the
6631 client is actually allowed to send traffic to network. The
6632 affected file is lib/silcclient/client.c.
6634 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6637 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6638 (if needs broadcasting) instead of broadcasting the packets one
6639 by one which would make a burst in the network traffic.
6641 * Added `broadcast' argument to the functions in silcd/server.[ch]
6642 silc_server_create_new_channel[_with_id] to indicate whether
6643 to send New Channel packet to primary router.
6645 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added new function into the silcd/server.[ch] files:
6648 silc_server_create_new_channel_with_id to create new channel with
6649 already existing Channel ID.
6651 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6652 lib/silccore/silcpacket.h. This packet is used t send list of
6653 Set Mode payloads inside one packet. Server uses this to set
6654 the modes for the channels and clients on those channels, that it
6655 announced to the router when it connected to it. The protocol
6656 specification has been updated accordingly.
6658 * The silc_server_new_channel did not handle the packet coming
6659 from normal server as it normally does not send that. However,
6660 when it announces its channels it does send it. Implemented
6661 the support for that.
6663 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6664 into the file lib/silccore/id.h.
6666 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Fixed memory leaks in the functions silc_idlist_del_client,
6669 silc_idlist_del_channel and silc_idlist_del_server in the file
6670 silcd/idlist.c. All of those leaked like a sieve.
6672 * Fixed some small memory leaks in the client's function
6673 silc_client_notify_by_server.
6675 * Added functions into silcd/server.c: silc_server_announce_clients,
6676 silc_server_announce_channels and silc_server_announce_server.
6677 These functions are used by normal and router server to announce
6678 to its primary router about clients, channels and servers (when
6679 router) that we own. This is done after we've connected to the
6682 These functions effectively implements the following packet types:
6683 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6684 and SILC_PACKET_NEW_ID_LIST.
6686 * Added new functions into the silcd/packet_receive.[ch]:
6687 silc_server_new_id_list, silc_server_new_channel_list and
6688 silc_server_new_channel_user_list to handle the incoming
6689 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6691 * Added support of changing Channel ID in the function
6692 silc_server_replace_id. If the server that announces a channel
6693 to the router already exists in the router (with same name but
6694 with different Channel ID), router is responsible to send
6695 Replace ID packet to the server and force the server to change
6696 the Channel ID to the one router has.
6698 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6699 client that the Channel ID has been changed by the router. The
6700 normal server sends this to the client. Client must start using
6701 the new Channel ID as the channel's ID.
6703 Implemented handling of this new type into lib/silcclient/client.c
6704 into the function silc_client_notify_by_server.
6706 * Added new function silc_idlist_replace_channel_id into the files
6707 silcd/idlist.[ch] to replace the Channel ID.
6709 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Call silc_server_command_identify_check always when processing
6712 the IDENTIFY command in silcd/command.c
6714 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6717 send keepalive packets. The packet can be sent by clients,
6718 servers and routers.
6720 Added function silc_socket_set_heartbeat into the file
6721 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6722 If not set, the heartbeat is not performed. The actual
6723 heartbeat is implemented in the low level socket connection
6724 library. However, application is responsible of actually
6727 Added silc_server_send_heartbeat to send the actual heartbeat
6728 packet into silcd/packet_send.[ch]. Server now performs
6729 keepalive with all connections.
6731 * Added silc_task_get_first function into lib/silcutil/silctask.c
6732 to return the timeout task with shortest timeout. There was a bug
6733 in task unregistration that caused problems. TODO has been
6734 updated to include that task system must be rewritten.
6736 * The client library will now resolve the client information when
6737 receiving JOIN notify from server for client that we know but
6738 have incomplete information.
6740 * Rewrote parts of silc_server_remove_from_channels and
6741 silc_server_remove_from_one_channel as they did not remove the
6742 channel in some circumstances even though they should've.
6744 * Encryption problem encountered in server:
6746 The LEAVE command used to send the Channel Key packet to the
6747 router immediately after generating it. However, the code
6748 had earlier sent Remove Channel user packet but not immediately,
6749 ie. it was put to queue. The order of packets in the router
6750 was that Channel Key packet was first and Remove Channel User
6751 packet was second, even though they were encrypted in the
6752 reverse order. For this reason, MAC check failed. Now, this
6753 is fixed by not sending the Channel Key packet immediately but
6754 putting it to queue. However, this is more fundamental problem:
6755 packets that are in queue should actually not be encrypted
6756 because packets that are sent immediately gets encrypted
6757 actually with wrong IV (and thus MAC check fails). So, packets
6758 that are in queue should be encrypted when they are sent to
6759 the wire and not when they put to the queue.
6761 However, the problem is that the current system has not been
6762 designed to work that way. Instead, the packet is encrypted
6763 as soon as possible and left to the queue. The queue is then
6764 just purged into wire. There won't be any fixes for this
6765 any time soon. So, the current semantic for packet sending
6768 o If you send packet to remote host and do not force the send
6769 (the packet will be in queue) then all subsequent packets to the
6770 same remote host must also be put to the queue. Only after the
6771 queue has been purged is it safe again to force the packet
6774 o If you send all packets immediately then it safe to send
6775 any of subsequent packets through the queue, however, after
6776 the first packet is put to queue then any subsequent packets
6777 must also be put to the queue.
6779 Follow these rules and everything works fine.
6781 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * Added new function silc_server_remove_clients_by_server to
6784 remove all client entries from ID list when the server connection
6785 is lost. In this case it is also important to invalidate all
6786 client entires as they hold the invalid server entry. This
6787 fixes fatal bug when server has lost connection and will reconnect
6790 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Made some sanity checks to silc_server_daemonise like to check
6793 whether the requested user and group actually exists.
6795 * Added sanity check to SKE's silc_ske_responder_finish to check
6796 that the public and private key actually is valid.
6798 * Invalidate the client's nickname when receiving Replace ID
6799 packet and the Client ID is being replaced. This means that the
6800 server will query the nickname if someone needs it (client)
6803 * Sort the ID Cache in client library when the ID Cache data
6804 has changed (needs sorting).
6806 * Do not allow for SILC client to create several connections to
6807 several servers. The client does not support windows right now
6808 and generating multiple connections causes weird behaviour.
6810 Irssi-silc client does support windows and can handle several
6811 connections without problems, see: www.irssi.org and SILC plugin.
6813 * Fixed some places where client was added to the IDList. The
6814 rule of thumb is following (in order to get everything right):
6815 If the client is directly connected local client then the
6816 `connection' argument must be set and `router' argument must be
6817 NULL to silc_idlist_add_client function. If the client is not
6818 directly connected client then the `router' argument must
6819 bet set and the `connection' argument must be NULL to the
6820 silc_idlist_add_client function.
6822 * The funtion silc_server_packet_send_local_channel actually did
6823 not check whether the client was locally connected or not. It
6824 does that now. Fixed a bug related to LEAVE command.
6826 * Fixed Remove Channel User payload parsing bug in server's
6827 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6829 * The server's silc_server_save_channel_key now checks also the
6830 global ID list for the channel as it might not be in the local
6831 list. Fixed a bug related to LEAVE command.
6833 * Is this the end of the [<unknown>] buglet that has been lurking
6834 around for a long time? A little for loop fix in server's
6835 silc_server_command_whois_parse that is used by both IDENTIFY
6836 and WHOIS command. At least, this was a clear bug and a cause
6837 of one type of [<unknown>] buglet.
6839 * WHOIS and IDENTIFY commands call the function
6840 silc_server_command_[whois/identify]_check function even if
6841 we are not router server.
6843 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Added --with-gmp configuration option. If set the GMP
6846 is always compiled in the SILC source tree. If not set then
6847 it is checked whether the system has the GMP3 installed. If
6848 it has then the GMP won't be compiled (the system's headers
6849 and library is used), if it doesn't have it then the GMP is
6850 compiled in the SILC source tree.
6852 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Changed RSA private exponent generation to what PKCS #1
6855 suggests. We try to find the smallest possible d by doing
6856 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6857 not security fix but optimization.
6859 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Added new config entry [Identity] to fork the server and run
6862 it as specific user and group. A patch from Bostik.
6864 * Imported Dotconf configuration library into lib/dotconf.
6865 This will be used to create the SILC configuration files later.
6866 It will appear in the distsribution after this commit.
6868 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * A big code auditing weekend happening. Auditing code for
6871 obvious mistakes, bugs and errors. Also, removing any code
6874 Removed files for being obsolete:
6876 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6877 inline in the file lib/silcutil/silcbuffer.h)
6879 o lib/silcutil/silcbufutil.c (the header has inline versions)
6881 Changed code to fix possible error conditions:
6883 o The buffer formatting routines now check that the destination
6884 buffer really has enough space to add the data. This applies for
6885 both buffer formatting and unformatting
6886 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6887 unformatting was changed to accomodate following rules:
6888 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6889 sent to the function while XXX_*STRING will not allocate or copy
6890 the data into the buffer. Instead it sets the pointer from the
6891 buffer into the pointer sent as argument (XXX_*STRING used to
6892 require that the pointer must be allocated already). This change
6893 makes this whole thing a bit more consistent and more optimized
6894 (note that the data returned in the unformatting with XXX_*STRING
6895 must not be freed now). The routines return now -1 on error.
6897 o Tried to find all code that use buffer_format and buffer_unformat
6898 and added return value checking to prevent formatting and
6899 especially unformatting errors and possible subsequent fatal
6902 o Changed ske->x and ske->KEY to mallocated pointers in
6903 lib/silcske/silcske.h. Fixed possible data and memory leak.
6905 o Added return value checking to all *_parse* functions. Fixed
6906 many memory leaks as well.
6908 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6909 so that buffer overflows would not happen. All code now also
6910 checks the return value as it can fail.
6912 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added reconnection support to server if the normal server looses
6915 its connection to the router (for example if router is rebooted).
6916 The server performs normal reconnection strategy implemented
6917 to the server. Affected file silcd/server.c.
6919 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Added new packet type SILC_PACKET_SET_MODE that is used to
6922 distribute the information about changed modes (for clients,
6923 channels and clients channel modes) to all routers in the
6924 network. Updated the protocol specification accordingly.
6926 Added functions into silcd/packet_send.c and
6927 silcd/packet_receive.c: silc_server_send_set_mode,
6928 silc_server_set_mode.
6930 Added new files silcmode.[ch] into lib/silccore that implements
6931 the encoding and decoding of Set Mode Payload. Added new type
6932 SilcSetModePayload. Moved the definitions of different modes
6933 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6935 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Oops, a little mistake in server's connection authentication
6938 protocol. The protocol is not ended with FAILURE but with
6939 SUCCESS if the authentication is Ok. :) Affected file is
6942 * Implemented NICK_CHANGE notify handling in server in the file
6943 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6944 the local clients on the channel. After the changing nickname
6945 in router environment snhould work and the [<unknown>] nickname
6946 should appear no more.
6948 The silc_server_replace_id function that receives the Replace ID
6949 payload now sends the NICK_CHANGE notify type also in the file
6950 silcd/packet_receive.c
6952 * Changed WHOIS and IDENTIFY command to support the maximum amount
6953 of arguments defined in protocol specs (3328 arguments). This
6954 fixed a bug that caused problems when there were more than three
6957 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * Added extra parameter, command identifier, to the
6960 silc_client_send_command so that explicit command identifier
6963 Changed that ID list routines uses specific command identifier
6964 when sending WHOIS/IDENTIFY requests to the server so that they
6965 can be identified when the reply comes back.
6967 Affected files lib/silcclient/command.[ch],
6968 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6970 * Added `sender' argument to silc_server_packet_send_to_channel
6971 to indicaet the sender who originally sent the packet to us
6972 that we are now re-sending. Ignored if NULL. Affected file
6973 silcd/packet_send.[ch].
6975 * Added some server statistics support in silcd/server_internal.h
6976 SilcServerStatistics structure and around the server code. Also
6977 send some nice statistics information when client is connecting
6980 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6982 * Fixed channel ID decoding in server's JOIN command reply in
6983 silcd/command_reply.c
6985 * Fixed braodcasting of replace ID payload to not to send it if
6986 we are standalone server in silcd/packet_receive.c.
6988 * Fixed all channel message sending routines to not to send
6989 packets to clients that has router set, since they are routed
6990 separately in the same function earlier. Affects file
6991 silcd/packet_send.c and all channel packet sending functions.
6993 * In USERS reply, res_argv[i] are not allocated, the table
6994 is allocated. Thus changed that free the table, not its
6997 * In server's whois_check and identify_check if the client is
6998 locally connected do not send any WHOIS commands - they are not
7001 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Fixed some minor bugs in client when sending WHOIS command. The
7004 arguments was in wrong order.
7006 * Removed statis function add_to_channel from server in
7007 silcd/command.c that was previously used with the joining but
7010 * Tested USERS command in router environment successfully with two
7011 routers, two servers and two clients.
7013 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * Reorganized the USERS command and command reply in client library
7016 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7017 When the command is given by user we register a pending command
7018 callback that will reprocess the command after the reply has been
7019 received from the server. When reprocessing the packet we then
7020 display the information. Thus, the USERS information is displayed
7021 now in the command callback instead of in the command reply
7022 callback. The processing of the command is same as previously
7023 when server has sent the command reply in the JOINing process.
7025 * Added to USERS command in silcd/command_reply.c to join the client,
7026 we didn't use to know about, to the channel after we've created
7027 a client entry for it. Also, for clienet we did know already still
7028 check whether it is on the channel or not and add it if not.
7030 * Removed silc_server_command_join_notify as the function and its
7033 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Changed the client's pending command handling to the same as the
7036 server's pending command handling. It is also now possible to
7037 execute command reply functions from other command reply
7038 function as the function callbacks for commands and command
7039 replies are one and same. The pending commands are not static
7040 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7041 in client connection context. Thus, pending commands are server
7042 connection specific as it is convenient.
7044 Changed the function silc_client_command_pending and
7045 silc_client_command_pending_del and added new function
7046 silc_client_command_pending_check. Removed the
7047 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7050 * Added cmd_ident, current command identifier, to the client
7051 connection context in lib/silcclient/client.h to keep track on
7052 command identifiers used in command sending. Client's command reply
7053 function handling now supports the mandatory command identifiers.
7055 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7056 funtions in client to fully support pending command callbacks.
7058 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7059 as one of the arguments to the application in the command reply
7062 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7063 before first releasing SILC but came back. Now it is removed again
7064 and should come back nomore. The FORWARDED flag was used only
7065 by the JOINing procedure by forwarding the command packet to router.
7066 Now, the JOINing procedure has been changed to more generic (due
7067 to various router environment issues) and FORWARDED is not needed
7068 anymore for anything. The protocol specification is yet to be
7071 Now, removed silc_server_packet_forward from server and the flag
7072 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7074 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * Renamed NAMES command to USERS command. The NAMES was named that
7077 due to historical reasons. Now it is renamed. Also, rewrote
7078 parts of the USERS command. The nickname list is not sent anymore
7079 by the server. Only Client ID and mode lists are sent in the USERS
7080 command. Changed this also to the protocol specification.
7082 The client now resolves the names and stuff after it receives
7083 the USERS list from the server when joining to the channel.
7085 * WHOIS and IDENTIFY commands has been changed to support multiple
7086 Client ID's per command. One can now search for multiple users
7087 in the network by sending only one WHOIS or IDENTIFY command.
7088 Changed the code and the protocol specifications.
7090 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7091 uses silc_server_command_whois_parse to parse the request. */
7093 * If normal server, do not parse the WHOIS and IDENTIFY requests
7094 before sending it to the router. Saves some time.
7096 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Fixed JOIN command on client library. Wrong number of arguments
7099 used to crash the client.
7101 * Added silc_server_channel_has_global function to check whether
7102 channel has global users or not.
7104 * Added silc_server_channel_has_local function to check whether channel
7105 has locally connected clients on the channel.
7107 * The silc_server_remove_from_one_channel now checks whether the
7108 channel has global users or not after given client was removed from
7109 the channel. It also checks whether the channel has local clients
7110 on the channel anymore. If it does not have then the channel entry
7111 is removed as it is not needed anymore.
7113 * The silc_server_notify now checks on JOIN notify whether the joining
7114 client is one of locally connected or global. If it is global then
7115 the channel has now global users on the channel and that is marked
7116 to the channel entry. Also, it now saves the global client to
7117 global list who is joining and JOINs it to the channel. This is
7118 for normal server, that is.
7120 Changed silc_server_send_notify_on_channel,
7121 silc_server_packet_relay_to_channel and
7122 silc_server_packet_send_to_channel check if we are normal server
7123 and client has router set (ie. global client) do not send the
7124 message to that client, as it is already routed to our router.
7126 * Implemented LEAVE notify type handling in silc_server_notify
7129 * Tested LEAVE command in router environment successfully. Tested
7130 with two routers, two servers and two clients.
7134 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7136 * Implemented SIGNOFF notify type handling in silc_server_notify
7139 * silc_server_remove_id now removes the client entry from all channels
7140 it has joined and thusly sends SIGNOFF notify type.
7142 * Rewrote the NAMES list generation in server by removing two excess
7143 loops. The lists are created now inside one loop.
7145 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7147 * silc_server_remove_channel_user checks now also global list
7148 for channel and client.
7150 * silc_server_new_channel_user checks now both local and global
7151 list for channel and client. Fixed a bug in client id decoding.
7152 Used to decode wrong buffer.
7154 * silc_server_channel_message checks now both local and global
7155 list for channel entry.
7157 * Tested channel joining (hence JOIN) in router environment
7158 successfully. Tested with two routers, two servers and two
7161 * Tested channel message sending in router environment successfully.
7163 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7165 * Added silc_server_save_channel_key into server.[ch] to save the
7166 received channel key in Channel Key payload processing. It is
7167 also used in JOIN command reply handling.
7169 Equivalent function silc_client_save_channel_key added into
7170 client.[ch] into client library.
7172 * Changed JOIN command reply to send information whether the channel
7173 was created or not (is existing already) and the channel key
7174 payload. Changed protocol specs accordingly.
7176 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7177 the request was sent by ID and not by nickname. Crashed on
7180 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7182 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7183 now correctly save the received data.
7185 * silc_server_free_sock_user_data now notifies routers in the
7186 network about entities leaving the network.
7188 At the same time implemented functions silc_server_remove_id
7189 and silc_server_send_remove_id to receive and send REMOVE_ID
7190 packets. The packet is used to notify routers in the network
7191 about leaving entities. The ID removed will become invalid in
7194 * Added function silc_idlist_del_server into server. Removes and
7195 free's server entry from ID list.
7197 * silc_server_private_message function now checks, if we are router,
7198 that the destination ID really is valid ID, naturally.
7200 * In router when NEW_ID packet is received (for new client) the
7201 hash of the Client ID is saved in the ID Cache but the
7202 client->nickname is set to NULL, instead of putting the hash
7205 IDENTIFY command now also checks that client->nickname must be
7206 valid. If it is not if will request the data from the server who
7207 owns the client. Added new function
7208 silc_server_command_identify_check.
7210 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7211 to set the command to already allocated Command Payload.
7213 * Tested private message sending in router environment with two
7214 routers, two servers and two clients. Fixed minor bugs and now
7217 * Fixed segfault from client's NAMES command. Used to crash if
7220 * Forwarded packets must not be routed even if it is not destined
7221 to the receiver. Changed server code comply with this.
7223 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Added `require_reverse_mapping' boolean value to ServerParams
7226 structure. If TRUE (not default) the server will require that
7227 the connecting host has fully qualified domain name.
7229 If the reverse mapping is not required and hostname could not be
7230 found the IP address is used as hostname.
7232 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7234 * Implemented version string checking to both client and server.
7235 The check is incomplete currently due to the abnormal version
7236 strings used in development version of SILC.
7238 * Changed all command functions in server to use the new
7241 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Changed char *data to unsigned char *data in ID Cache system to
7244 support binary data as ID Cache data. Changed code to support
7245 binary data in lib/silccore/idcache.c.
7247 * Renamed silc_server_packet_relay_command_reply to
7248 silc_server_command_reply as it is normal packet receiving
7249 function. Rewrote the function to accept command replys for
7250 servers and not only for clients.
7252 * Mark remote router always as registered server if we are connecting
7253 to it. Otherwise, commands sent by the router to us are ignored.
7255 * All ID List find routines now returns the ID Cache Entry pointer
7256 as well if requested.
7258 * WHOIS command works now in router environment, tested with two
7259 routers, two servers and two clients.
7261 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7262 in router environment (as it is almost equivalent to WHOIS) but
7263 hasn't been tested thoroughly. Added new functions:
7265 silc_server_command_identify_parse
7266 silc_server_command_identify_send_reply
7267 silc_server_command_identify_from_client
7268 silc_server_command_identify_from_server
7270 * Disabled route cache adding because adding two different ID's with
7271 same IP replaces the old cache entry thus giving wrong route.
7272 The entry->router->connection is always the fastest route anyway
7273 so route cache may not be needed. Of course, new routes maybe
7274 established after receiving the ID when the entry->router->connection
7275 might not be anymore the most optimal.
7277 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Add route cache for received ID for fast routing.
7281 * Added silc_server_packet_route to route received packet on router
7282 that is not destined to us.
7284 * Renamed silc_server_get_route to silc_server_route_get.
7286 * Added id_string and id_string_len fields into SilcServer to
7287 include encoded ServerID for fast comparing without excess
7288 encoding of the ID's.
7290 * Cleaned up WHOIS command on server side. Added following static
7293 silc_server_command_whois_parse
7294 silc_server_command_whois_check
7295 silc_server_command_whois_send_reply
7296 silc_server_command_whois_from_client
7297 silc_server_command_whois_from_server
7299 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7300 arguments in command replies. All command functions should be
7301 updated to use this macro.
7303 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Minor typo fixes on command reply handling on server.
7307 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Added silc_server_command_add_to_channel internal routine to add
7310 the client to the channel after router has created the channel and
7311 sent command reply to the server.
7313 * Added generic silc_server_send_command to send any command from
7316 * Use static buffer with ID rendering instead of duplicating data.
7318 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Fixed a channel user mode bug when joining to a channel server gave
7321 everybody channel founder rights, oops.
7323 * We mark ourselves as the router of the incoming server connection
7324 if we are router ourselves. This way we can check in some packet
7325 sending functions whether it is locally connected server. For
7326 incoming router connections we put NULL.
7328 * For router sending packets locally means now always sending the
7329 packet cell wide; to local clients and local servers. For normal
7330 server sending packet locally means sending it to only local
7333 * Fixed the JOIN command to really work in router environment. If the
7334 channel is created it is always created by the router. Router is
7335 also responsible of making the initial joining to the channel,
7336 sending JOIN notify to the sending server and distributing
7337 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7338 does not exist server doesn't do anything else but forward the
7339 command to the router which performs everything.
7341 * Added silc_server_send_channel_key function to send the Channel Key
7344 * Added silc_server_create_channel_key to create new channel key. The
7345 channel key is now re-generated everytime someone joins or leaves
7346 a channel, as protocol dictates. Note: channel->key_len is the
7349 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7352 packet_receive.[ch] to separate packet sending and receiving
7353 routines. The server.[ch] now includes everything else including
7354 actual packet processing (writing and reading data) and other
7357 Renamed silc_server_private_message_send_internal to
7358 silc_server_send_private_message. The routine is still though
7359 used only to relay private messages as server does not send
7360 private messages itself.
7362 Renamed silc_server_new_channel to silc_server_create_new_channel
7363 and added new function sicl_server_new_channel that handles the
7364 incoming New Channel packet. Added also new sending function
7365 silc_server_send_new_channel to send New Channel Payload.
7367 * Added new function silc_server_notify to process incoming notify
7368 packet to the server/router. Server may then relay the notify
7369 to clients if needed.
7371 * Added new function silc_server_new_channel_user to process incoming
7372 New Channel User packet. Router will redistribute the packet and
7373 send JOIN notify to its local clients and locally connected servers
7374 if needed. Normal server will send JOIN notify to its local client
7375 on same channel when received this packet. Added also corresponding
7376 sending function silc_server_send_new_channel_user to sent the
7379 * Added boolean route argument to send_notif_to_channel and
7380 packet_send_to_channel functions to attempt to route the packet
7381 if it is TRUE and send only locally if it is FALSE.
7383 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * silc_server_replace_id now broadcasts the received replace ID
7386 packet if it is not broadcast packet already. The router must
7387 broadcast to inform other routers about changed ID.
7389 * Added backpointer to server's router into SilcServer context in
7390 silcd/server_internal.h.
7392 * Fixed silc_server_packet_broadcast to send correct broadcast
7395 * The channel key is now distributed to the local client as soon
7396 as it is received from the router (in router environment) so that
7397 no other packet may be sent for the channel until client has
7400 * silc_server_remove_channel_user now broadcasts the received
7401 Remove Channel User packet if it is not broadcast packet already.
7402 The router must broadcast to inform other routers about removed
7405 * Added users field into SilcPacketContext that is a reference count
7406 of the context. One can increase the reference count by calling
7407 silc_packet_context_dup which is now changed to just increase the
7408 reference count instead of duplicating the data. The reference
7409 count is decresed by calling silc_packet_context_free that will
7410 free the data after the reference count hits zero.
7412 For now on the packet context and everything allocated into it
7413 (including the raw packet from network) must be freed by calling
7414 the new silc_packet_context_free function. Added also new function
7415 silc_packet_context_alloc that must be used now to allocate the
7416 context. This also means that if a routine is asynchronous from
7417 silc_[client/server]_packet_parse_type the packet context must
7418 be duplicated by calling silc_packet_context_dup. Otherwise it
7419 gets free'd after silc_[client/server]_packet_parse_type returns.
7420 Also, one must remember that if packet is duplicated then its
7421 reference count must be decresed by calling the free function as
7422 many times as it was duplicated.
7424 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7425 from both client and server.
7427 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7429 * Made joining to a channel working in router environment.
7431 * Cleaned up JOIN command on server side and create function
7432 silc_server_command_join_channel internal routine to make the
7435 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Changed silc_command_pending list to SilcDList. Also, added
7438 `ident' field to SilcServerCommandPending structure to identify
7439 the reply and to call correct callback.
7441 Added silc_server_command_pending_check function to replace the
7442 corresnponding macro. The silc_command_pending list is not
7445 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7446 to set identifier to previously allocated Command Payload. It
7447 is used to set identifier for command when resending Command
7450 * Added silc_command_payload_encode_payload to encode Command
7451 Payload buffer from SilcCommandPayload structure.
7453 * Added silc_argument_payload_encode_payload to encode Argument
7454 payload buffer from SilcArgumentPayload structure.
7456 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Changed WHOIS command to support router connection on server side.
7459 The whois request is always sent to router unless the server is
7460 standalone server. After server has received the reply from the
7461 router will it send the reply to the client.
7463 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7464 broadcast received broadcast packet. The function is used only
7465 by router. The broadcast packet is always sent to the router's
7468 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7469 render given ID to printable string, for log files for example.
7471 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Made basic router to router connections working. At least they
7474 can now connect to each other but nothing really works the way
7475 they are supposed - yet.
7477 * Added new initiator token to RouterConnection configuration
7478 file in silcd/serverconfig.[ch]. It is used to tell whether we
7479 are the initiator to the remote router or whether we'll expect
7480 the other end to connect.
7482 * Moved registering of listener task to silc_server_init, hence
7483 the server starts listenning as soon as it is run, even if it
7484 does not have connections to other routers. Let's see how well
7487 * Changed default connection retry timeouts for more suitable in
7490 * Removed cipher and such arguments from silc_idlist_add_client
7491 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7492 Added new function silc_idlist_add_data to add the keys and stuff
7495 * Added SilcIDListData structure and added it to SilcClientEntry
7496 and SilcServerEntry as their first field in the structure. This
7497 way we can explicitly cast the ID entries to the SilcIDListData
7498 structure and get common data for the entries. In past, we had
7499 to first check what type of connection it is and then cast it to
7500 correct ID entry type. Now, we can directly cast the opaque
7501 pointer to the SilcIDListData (no matter what ID entry it actually
7502 is) and get the data needed.
7504 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7507 in some circumstances even if threre were timeout tasks, though not
7508 IO tasks, but tasks anyway. Now fixed.
7510 * Defined SilcServerConnection structure to hold connection specific
7511 stuff about directly connected servers and routers. The definition
7512 is currently in silcd/server_internal.h. I thought about having
7513 a bit more important role fro this struct but for now it is used
7514 only when connecting to other server (or router actually).
7516 * Added connecting retry support in server when connecting to
7517 router(s). The retry feature implement exponential backoff
7518 algorithm. Also, added SilcServerParams structure to hold default
7519 parameters for server. For now, it include these retry settings
7520 and are hard coded. After server is moded to be as Silc Server
7521 Library this structure will be more important.
7523 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Changed client librarys channel->clients table to SilcList and
7526 changed code accordingly.
7528 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7530 * Changed client's channel table to SilcList and changed code
7531 accordingly. Also changed SilcChannelClientEntry to include back-
7532 pointer to the channel so that client entry can use that structure
7533 as list as well and we have fast cross-reference to the channel.
7534 This change dramatically decreased the complexity of channel
7535 handling with client entry and vice versa (removed one extra
7536 loop when searching for channel entry from many functions).
7538 * Changed server->sim from table to SilcDList and changed code
7541 * NAMES command can now be used from user interface. It will show
7542 the user list on the channel, neatly.
7544 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7545 Code now saves realname of the user if it becomes available.
7547 * Renamed configure.in to configure.in.pre and made ./prepare
7548 script to automatically add correct version string to
7549 configure.in which it creates from configure.in.pre.
7551 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * NAMES command reply now shows users mode with the nickname when
7556 * Moved silc_client_ch[u]mode[_char] functions from
7557 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7558 place sucks, they are utility functions and should be in some
7561 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7563 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7566 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7570 * Added TRQ (efficient deque and list library) into lib/trq. This is
7571 a very good list library that is currently used in the SILC. Defined
7572 SilcList API over the library because I didn't like the API very
7573 much. See lib/trq/silclist.h for the API and examples of how to
7574 use the API. Fixed various places in the code to use the new
7575 SilcList API. The SilcList is meant for lists that has a structure
7576 already defined as a list. It is not suitable to add just some
7577 context to the list (in TRQ, the context is the list actually).
7579 So, I defined SilcDList that can be used for the purpose where
7580 predefined list structure does not exit. This can be used as
7581 such list. Now some context just can be added to the SilcDList.
7582 Currently this list is not used in the SILC just yet, though there
7583 are a lot places where this can replace dynamically allocated
7584 tables and I will fix these places, later, to use SilcDList.
7585 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7586 and use TRQ internally).
7588 Also fixed some annoying warning messages that the original TRQ
7589 code generated. Also minor changes to TRQ's Makefile.in.
7591 * Added support for querying by Client ID to both WHOIS and
7592 IDENTIFY commands into server, as required by the protocol.
7594 * Removed method function pointers from SilcBuffer structure. They
7595 weren't used to anything and just increased the context size for
7596 no good reason. This change also made silc_buffer_alloc and
7597 silc_buffer_free functions inline functions.
7599 * Disabled command flooding detection support until it's fixed so
7600 that it accepts commands in but does not execute them more than once
7603 * Added silc_net_localhost(), to return local hostname, into
7604 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7605 that must be initialized before calling silc_client_init.
7607 * Added new function: silc_server_send_notify_on_channels to send
7608 notify messages to all channels client has joined. It is assured
7609 that the message is sent only once per client.
7611 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7612 lib/silcutil/silcutil.[ch] as silc_format function. The new
7613 function is generic and is used by server as well, not only by
7614 the logging routines.
7616 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7617 the provided version string was not acceptable. Added new function:
7618 silc_ske_check_version into lib/silcske/silcske.h. The function
7619 must be implemented by the application (client or server) and it
7620 does not reside in the SKE library. The function checks the version
7621 string remote end sent.
7623 * Added back pointers (to opaque context and to SilcSocketConnection)
7624 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7626 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7627 duplicate packet context structure.
7629 * Changed `notify' client operation to send same arguments as client
7630 receives from server except for ID's. ID's are mapped to correct
7631 ID entry and that is returned. Also, if channel entry is not sent
7632 by server but the notify is for channel the channel entry is sent
7633 to application (otherwise application doesn't know that it is for
7634 channel (library gets it from packet's Destination ID)).
7636 * Added silc_client_remove_from_channels into client library to
7637 remove a client from all channels it has joined to. Used when
7638 received SIGNOFF notify from server. Added also new function
7639 silc_client_replace_from_channels to replace old ID entry with
7640 new ID entry on all channels. Used when received NICK_CHANGE
7643 * Fixed ID Cache list handling in silc_idlist_get_client in
7644 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7645 to get (or query) client by ID.
7647 * Updated TODO list.
7649 * Added connection authentication status message defined by the
7650 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7651 support for these into the code in client and server side.
7653 * Added generic function silc_client_send_command to send any command
7654 with variable argument list. Application should use this function
7655 to send commands if the command functions provided by the library
7656 does not suite for the application's user interface needs.
7658 * Added new `failure' client operation. Application is notified about
7659 received failure packet if client is executing a protocol. In this
7660 case the protocol's execution has failed.
7662 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7663 is required by the protocol.
7665 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7666 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7669 * Added status flag to SilcSKE object to indicate realtime status
7670 of the SKE protocol.
7672 * Application receives now exactly same command reply arguments as
7673 the library receives from server. However, if ID is received the
7674 corresponding ID entry is returned to the application (eg. Client
7675 ID is mapped to correct SilcClientEntry entry and that is returned).
7676 Changed command_reply client operation due to this change.
7678 * Changed all ID's in commands and in command replys as ID Payloads.
7679 Change affected both client and server side codes.
7681 All ID's sent in SILC network (with execption of ID's in SILC
7682 Packet header) are sent in ID Payload to support variable length
7685 * Server now notifies nick changes and notifies all clients on
7686 the channels about the new nickname (about the new Client ID,
7689 * Implemented CMODE command to change channel modes. Supports all
7690 channel modes defined by the protocol specs except ban and invite
7691 lists. (Also, private channel key mode is supported but support for
7692 setting private channel key in client is missing, thus, this mode
7693 has no effect on client side (except that server requires that the
7694 client uses private channel key and normal channel traffic does not
7697 Also, invite mode works per se, but INVITE command does not work
7698 yet correctly, so you can set channel as invite only channel but
7699 inviting clients to the channel does not work (it is yet to be
7700 thought what's the best way to do it).
7702 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7703 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7704 Implemented CUMODE command to change user's mode on the channel.
7705 Supports all modes defined by the protocol specs.
7707 * Added NAMES command reply to return users modes on the channel.
7709 * Removed unnecessary and slow ciphers from lib/silccrypt.
7711 * Set SO_KEEPALIVE option to connection sockets by default.
7713 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7715 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7716 redefined the Notify Payload into protocol specs.
7718 * Added silc_id_payload_parse_id to get ID directly from raw
7721 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7723 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7724 accept searching by Client ID as well.
7726 * Added support for LEAVE and SIGNOFF notify types in client library.
7728 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7729 to parse ID Payload from raw data.
7731 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7733 * Added flags parameter into silc_ske_assemble_security_properties
7734 function in lib/silcske/silcske.[ch].
7736 * Changed notify client operation to fit better for notify messages
7737 sent by server. The notify payload received from server is now
7738 passed to the application (after parsing it to SilcNotifyPayload).
7739 It is application's responsibility to retrieve the arguments
7740 from the payload and show the message the way it wants. The message
7741 sent by server is implementation specific.
7743 * Changed public keys to comply with the protocol specification.
7744 Old public keys are not supported anymore and are not compatible.
7746 * Removed nickname from Channel Payload as the latest draft removed
7747 it. The client must resolve the nickname from the NAMES command
7748 reply received when it joined the channel.
7750 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7752 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * Fixed some errors in protocol specification drafts.
7756 * Created lib/silccore/silcnotify.c to implement Notify Payload
7757 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7758 generic payloads described by protocol specifications. The file
7759 includes implementations for ID Payload and Argument Payload.
7761 * Changed Command Payload implementation to use the new Argument
7762 Payload. Changed command_xxxx_payload to command_payload_xxxx
7763 to comply with SILC coding conventions.
7765 * Added suppport for Argument Payload handling in Notify Payload
7766 implementation as protocol requires it. Added the new support
7767 into server and client lib as well.
7769 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Added support for multiple nicknames on same channel. [n] is
7772 added locally to the nickname if there are more than one same
7773 nicknames on the channel.
7775 * Server now sends all nicknames that matched WHOIS request.
7776 Client also shows the list received from server.
7778 * Added TOPIC command to client side. User can now set and show
7779 current topic on channel.
7781 * Added MOTD command to client and server. Also, server sends the
7782 motd when client connects to the server.
7784 * Changed version strings to comply ISO 8601.
7786 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7788 * Fixed protocol error handling in client library. It should now
7789 cope even if the SKE fails for some reason.
7791 * Made new protocol specification drafts for submitting to IETF.
7793 * Implemented TOPIC command to server in silcd/command.c.
7795 * Added two new notify types into lib/silccore/silcnotify.h:
7796 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7797 notify nickname change and topic setting/change on a channel.
7799 * API change of command_reply operation in client library. The
7800 application gets now the status type received from server as well.
7802 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7804 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7806 * Cras fixed and optimized the packet handling even further and
7807 it should work now. Minor change to the prototype of function
7808 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7810 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Added new function into lib/silcutil/silcschedule.[ch]:
7813 silc_schedule_with_fd to select() a specified fd. The function
7814 returns after timeout expires or data arrives or goes. The
7815 function is used by packet routines to wait that all data is
7816 received from network.
7818 * Fixed data reading from network in lib/silccore/silcpacket.c.
7819 The code now assures that all data is read from the fd and then
7820 continues packet processing. This was a bug fix since the code
7821 used to drop some data in some circumstances.
7823 * Added new function into lib/silcclient/client.[ch]:
7824 silc_client_start_key_exchange to start key exchange after
7825 connection has been established to server. The code internally
7826 now uses this funtion but its main purpose was to provide it
7827 for applications that perform their own connecting. After
7828 application has created a connection it merely calls this
7829 function to start the key exchange between client and server.
7830 The library takes care of everything else after that.
7832 Updated also lib/silcclient/README to explain the usage of
7835 * Do not send to application information that connection has
7836 been established. Application gets notified it by connect
7839 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7841 * Applied cras's patch to add silc_schedule_one function. The
7842 function runs scheduler once and returns.
7844 * Fixed the scheduler after cras messed it up. The timeout
7845 handling works now as it's supposed to work.
7847 * Added into lib/silccore/ silcnotify.h to include notify
7848 message types support. Changed silc_server_send_notify*
7849 functions, in server.[ch], to support those new notify types.
7850 Added the support for the notify types into client library,
7851 as well. Added new notify client operation into ops.h in
7854 * Changed silc_server_packet_send_to_channel to send normal
7855 packets instead of just channel message packets. The function
7856 is now used to send the notify packets to channels. It is not
7857 used to send channel message packets anymore, as server never
7860 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7861 va_arg()s as it seems to require it nowadays. I guess, if SILC
7862 is compiled with older va_arg() the new code should work anyway.
7864 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7866 * Splitted core library. Core library (lib/silccore) includes
7867 now only SILC protocol specific core (and common) components.
7868 Created new utility library (lib/silcutil) that includes more
7869 generic purpose stuff. The stuff for util library was taken
7870 from the old core library. This was minor and easy split.
7872 * Created SILC Client Library (lib/silcclient) that includes
7873 implementation of the SILC client without user interface. This
7874 was major move from silc/ directory. The code has been changed
7875 so that it is transparent towards the user interface. The
7876 silc/ directory includes now the same user interface as before
7877 and it uses the new client library. Read lib/silcclient/README.
7878 Basicly, the client library performs everything else related
7879 to SILC except user interface handling. Also, configuration
7880 files are considered to be part of user interface and library
7881 does not handle them.
7883 This change also changed a lot of structures, function naming etc.
7884 Most important change was that SilcClientWindow object was
7885 renamed to SilcClientConnection in the client library. Created
7886 also new file lib/silcclient/ops.h. Also added new files
7887 silc/local_command.[ch] and silc/client_ops.[ch].
7889 All these changes were made to make it easier for user interface
7890 designers to create what ever user interface for the SILC client
7893 It is also expected that the server will be moved to lib
7894 directory as well and SILC Server Library will be created;
7895 sometimes in the future.
7897 * Removed Local commands from lib/silccore/silccommand.h as
7898 they are application specific and new client library does not
7899 handle any of those anymore.
7901 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7902 old client implementation in silc/.
7904 * Added support for callback functions in SILC_LOG_* macros.
7905 Application can now set its own callbacks that will be called
7906 instead of using the default functions that will always print
7907 the debug messages to stderr (or stdout). Also, debugging can
7908 now be disabled by setting silc_debug to FALSE and re-enabled by
7909 setting it to TRUE. Note, that logging will still work even
7910 if debugging is disabled.
7912 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7913 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7914 silc_log_reset_debug_callbacks.
7916 * To enable debugging in silc client one must give now -d
7917 option on command line.
7919 * Changed silc_schedule_init to automatically allocate task queues
7920 if they are not allocated before calling it.
7922 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Added GMP 3.1 into math library.
7926 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7928 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7929 a channel in SILC network. The packet is used by servers and
7930 routers to notify other routers that user has left a channel.
7931 This little feature was missing until now. Added the feature
7932 to protocol specification as well.
7934 Added functions: silc_server_send_remove_channel_user and
7935 silc_server_remove_channel_user into server.[ch].
7937 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7938 lib/silccore/silcpacket.h. However, they are not implemented
7941 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7943 * Fixed joining to a channel and sending channel messages
7944 between server and router. The channel message sending should
7945 now work inside a cell.
7947 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7949 * Fixed the private message sending between server and router.
7950 The private message sending should now work inside a cell.
7952 * Added silc_server_replace_id into server.[ch] to replace
7953 existing ID in the SILC network.
7955 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7956 and silc_idlist_replace_server_id into idlist.[ch] in server.
7958 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7960 * Fixed the server to server connections. Server can again now
7961 connect to router. Router to router connections probably does
7964 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7966 * Added dynamic protocol registering support. Now protocols can
7967 registered and unregistered on the fly. Patch by cras.
7969 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7971 * Added lib/contrib directory to hold routines that some platforms
7972 don't have but are needed by SILC.
7974 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7975 into lin/contrib to provide getopt() and getopt_long() for
7976 those who don't have it.
7978 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Added AWAY command to client. When away message is set and
7981 client receives a private message packet the client automatically
7982 replies to the sender with the away message.
7984 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7985 bug seemed to be the cause of recent problems when compiling
7988 * Added version detection support to SKE protocol specification
7989 and added the new changes to the SKE implementation as well.
7990 There were other minor changes in the SKE protocol as well.
7992 Many changes in lib/silcske/silcske.[ch] and in
7993 lib/silcske/payload.[ch].
7995 * Added ^U functionality, clear input line. Patch from cras.
7997 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7999 * Mainly small bugfixes on core library. Fixed some debugging
8000 logging and buffer overflow in silclog.c.
8002 * Updated config.sub and config.guess on the distribution tree.
8004 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Added command lagging support in server. Client may execute
8007 commands now only once in two seconds.
8009 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Optimized packet reception. MAC computation and checking is now
8012 also more optimized. A lot previously duplicated code is now
8013 used as generic by both client and server.
8015 * Fixed key pair generation in clientutil.c
8017 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Added into lib/silccore/silcbufutil.[ch] new function;
8020 silc_buffer_realloc.
8022 * Moved generic packet sending/encryption functions to
8023 lib/silccore/silcpacket.[ch] from client and server. Some
8024 rewriting of the functions.
8026 * Moved all generic packet reception/decryption functions to
8027 lib/silccore/silcpacket.[ch] from client and server. The
8028 packet processing is now much cleaner in both client and server.
8029 These were major changes in both client and server.
8031 * Created many common functions in server to do packet sending.
8032 Previously code were duplicated a lot, this has been removed
8035 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8037 * Rewrote major parts of the ID cache system. Don't know
8038 whether it is better now or not but at least the API is more
8041 * Major rewrite on ID cache stuff on client because of the ID
8042 cache API changes. Added idlist.c to client.
8044 * Also major rewrite on ID cache stuff on server as well.
8045 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8046 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8047 in hand, instead they are all put into the ID cache system now.
8048 All server_idlist_* routines uses ID cache now instead of
8049 traversing its own lists (those lists does not exist anymore).
8050 SilcIDList though still exists. Also, SilcXXXEntry's are
8053 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Finally made the SKE implementation compliant to the protocol
8056 specification. All mp integers are now binary encoded as
8057 opposed being HEX encoded.
8059 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8062 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8063 functions: silc_[encode/decode]_pem. Also added function
8064 silc_encode_pem_file to PEM encode with newlines ('\n') for
8067 * SILC public keys are now encoded either PEM or binary. Same
8068 option is for private keys as well. By default private keys
8069 are binary encoded and public keys PEM encoded. Silly HEX
8070 encoding were removed.
8072 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8073 function to create fingerprints.
8075 * Fixed a bug in SHA1; does not change the original data anymore.
8077 * Partly implemented INFO command on client and server side.
8078 Fixed CLEAR command. Changes to SERVER command; show current
8079 server(s) when giving command without arguments. Added
8080 VERSION command to client.
8082 * Added check to server that unregistered connections cannot
8083 execute commands (unless it is specificly allowed).
8085 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8087 * Fixed screen refresh.
8089 * Fixed channel joining bug from client. On some circumstances
8090 client tried to join to a channel it had already joined.
8092 * Added public key verification process into client's protocol.c.
8093 The client now verifies the public key from user and saves
8094 it into ~./silc/serverkeys/ directory.
8096 Added into: clientutil.[ch]: silc_client_verify_server_key.
8098 * Changed SKE protocol's silc_ske_initiator_finish function
8099 to accept callback function that verifies the received public
8100 key. Removed old silc_ske_verify_public_key function.
8102 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8104 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8105 silc_pkcs_private_key[_data]_set.
8107 * Made the password and public authentication more cleaner in
8108 server's protocol.c.
8110 * Removed historic and obsolete protocol `channel_auth' from
8111 both client and server.
8113 * Removed wrong way of sending command status messages from
8114 server to client in server's command.c. The old way violated
8115 protocol specification.
8117 Changes to silccore/silccommand.[ch]: removed
8118 silc_command_encode_status_payload -> not needed anymore,
8119 changed silc_command_encode_payload_va to accept extra
8120 argument on variable argument list. The argument type must
8121 now be provided to the function. Also, added new function:
8122 silc_command_encode_reply_payload_va which is same as
8123 normal command_encode_payload_va except command status type
8124 is provided as extra argument.
8126 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8128 * Added ~./silc directory handling. The directory includes the
8129 public and private keys for the client.
8131 Added silc_client_check_silc_dir, silc_client_create_identifier
8132 and silc_client_load_keys.
8134 * Implemented SILC protocol compliant public key. Added public
8135 and private key saving to and loading from files.
8137 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8138 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8139 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8140 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8141 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8143 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8144 silc_pkcs_load_[public/private]_key.
8146 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Added silc_server_get_route (route.[ch]) to get connection
8149 data for the fastest route for given ID.
8151 * Implemented INVITE command on client and server. The command
8152 were re-defined in the SILC Protocol Specification and the
8153 implementation now complies with the specification.
8155 * Implemented PING command on client and server.
8157 * Implemented NAMES command on client and server. The server side
8158 supports currently only normal server not router server yet.
8159 Some changes to NAMES definition in SILC protocol specification.
8161 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Implemented LEAVE command on client and server.
8165 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8166 again. This change was made to the protocol as well. Server
8167 should not violate the protocol specification anymore.
8169 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8171 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8172 was tested. SOCKS4 was not but should work anyway.
