1 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added preliminary support for native WIN32 compilation under
4 cygwin (using the -mno-cygwin option for GCC) to the
5 ./configure.in.pre. The --with-win32 now prepares the
6 compilation for native WIN32.
8 * Rewrote the SILC Scheduler interface in the file
9 lib/silcutil/silcschedule.h. The scheduler is now context
10 based and does not have anymore any global static scheduler.
11 Moved the Unix scheduler to the lib/silcutil/unix/ directory
12 and created lib/silcutil/win32 directory for WIN32 based
15 * Added Unix specific network routines to the
16 lib/silcutil/unix/silcunixnet.c and the old
17 lib/silcutil/silcnet.c includes now only generic routines.
19 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Do not handle JOIN notify in the server if the target client
22 is not registered (idata->registered == FALSE). The affected
23 file is silcd/packet_receive.c.
25 * Update the nickrec->founder in event_cumode in the Irssi SILC
26 client. Affected file irssi/src/silc/core/silc-channels.c.
28 * Fixed the CUMODE_CHANGE notify handling in the server when
29 server and router are announcing their clients on channels.
30 Now the mode changes are saved and notified correctly. The
31 affected file is /silcd/packet_receive.c.
33 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
34 They really did not replace the cache entry in the ID Cache.
35 Now they do that. Affected file silcd/idlist.c.
37 * Fixed the KICK notify handling in the Irssi SILC client to
38 update the channel records so that the kicked client does not
39 appear to be on the channel. The affected file is
40 irssi/src/silc/core/silc-channels.c.
42 * Always update the conn->current_channel when executing command
43 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
45 * Fixed the KILL notify handling in Irssi SILC client to remove
46 the killed client on all channels.
48 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
50 * Fixed the silc_parse_command_line to remove extra spaces
51 from the start and end of the arguments. Affected file is
52 lib/silcutil/silcutil.c.
54 * Cancel and free any active protocol in the function
55 silc_server_close_connection. Affected file silcd/server.c.
57 * Cancel and free any active protocol in the function
58 silc_client_close_connction. Affected file is
59 lib/silcclient/client.c.
61 * Do not execute the KILL command for clients that are in
62 history (ie. they are not in the network). Affected file is
65 * Fixed KILL notify handling, client does not crash anymore.
66 Affected file irssi/src/silc/core/silc-channels.c.
68 * Reduced the default packet buffer size from 2048 to 1024 in
69 lib/silccore/silcpacket.c.
71 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
72 counter to the SKE context that is incresed when the SKE library
73 performs async operation outside the library. If the outside
74 process frees the SKE context and FREED status will be set
75 and the library will detect after the sync operation that the
76 libary is freed. The affected files are
77 lib/silcske/silcske[_status].[ch].
79 * Resolve the client entry information in the function
80 silc_client_channel_message to assure that NULL pointer is not
81 passed as client entry to the application. */
83 * Fixed the task timeout calculation to assure that there is
84 never negative timeouts. The affected file is
85 lib/silcutil/silcschedule.c.
87 * Fixed the channel user mode notification sending in server.
88 It was sent point-to-point to the router (or to server by router)
89 but it needs to be destined to a channel. The routines now
90 supports sending the channel user mode notifys to the channels
91 when announcing clients and channels. Affected files are
92 silcd/server.c and silcd/packet_receive.c.
94 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
95 It did not actually replace the old channel entry in the cache.
96 Affected file lib/silcclient/client_notify.c.
98 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
100 * Fixed a possible crash in silc_packet_send_prepare. It now
101 assures always that there is enough space in the buffer and
102 at the tail area of the buffer (for MAC).
104 Fixed the inbound buffer reallocation in silc_packet_read.
105 It was old code and did not handle the reallocation correctly.
108 The affected file is lib/silccore/silcpacket.c.
110 * Fixed buffer overflow in silc_parse_nickname in the file
111 lib/silcutil/silcutil.c.
113 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * make install generates new server keys only if there is not
118 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
121 Added check that if the NOREPLY is set then we will not send
122 the away message. This avoids infinite loop of away messages
123 if both clients are away. The affected file is
124 lib/silcclient/client_prvmsg.c.
126 * Fixed client crash if /NICK was given without arguments.
127 Affected file lib/silcclient/command.c.
129 * Server does not send the invite list in INVITE command back
130 to the client if the list was not altered. Added this notion
131 to the protocol spec as well. Affected file silcd/command.c.
133 Fixed possible crash in INVITE command by checking the
134 value of silc_server_get_client_route command.
136 * Fixed the INVITE notify type handling. The arguments are now
137 taken in correct order and client does not crash. The affected
138 file is irssi/src/silc/core/silc-channels.c.
140 Removed the "Inviting xxx to channel" message from the
141 client library away and let the application handle it.
142 Affected file lib/silcclient/command.c. Added that message
143 to Irssi SILC client's message formats.
145 * Fixed CMODE command crash in client. It now checks the
146 amount of arguments correctly and does not crash. The affected
147 file is lib/silcclient/command.c.
149 * Do not create new channel automatically in silc_channels_join
150 but check whether the channel by that name already exists.
151 Affected file irssi/silc/core/silc-channels.c.
153 * Do not send the SERVER_SIGNOFF to router if the disconnected
154 entity was the router. Affected file silcd/server.c.
156 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
157 SILC client as it was missing from there.
159 Added the handling of the KICK notify to the Irssi SILC client
160 as it was missing. Added "you have been kicked" message to
161 Irssi SILC client's message modules formats.
163 Added the handing of the KILL notify to the Irssi SILC client
164 as it was missing. Added the kill message module formats
167 The affected file is irssi/src/silc/core/silc-channels.c.
169 * The router did not save the channel mode the server announced.
170 Affected file silcd/packet_receive.c.
172 * Fixed a possible crash in INFO command in server. If the
173 server did not provide the server info it crashed. Affected
174 file silcd/command.c.
176 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Fixed the GETKEY command in the server to check also the
179 global list. Otherwise the GETKEY would not work correctly
180 in normal SILC server. Affected file silcd/command.c.
182 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Fixed GETKEY crash, it crashed if the command did not succseed.
186 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
189 is now real and not just an macro interface to GMP.
191 Removed the entire GMP from the source tree and imported new
192 NSS MPI library instead. Reason for removing GMP is that it is
193 extremely large and compiles extremely slow. The NSS MPI
194 is only a few files and compiles in less than 10 seconds.
195 The speed is also about the same as GMP. The MPI is imported
198 If the system has GMP installed we will still use the GMP.
199 If it is not then the NSS MPI will be compiled.
201 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Merged a long nickname (127 characters long) crash bugfix from
204 Irssi CVS tree. Affected file irssi/src/core/misc.c.
206 * Merged a freed memory reference bugfix from Irssi CVS tree.
207 Affected file irssi/src/core/commands.c.
209 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Added the server's public key sving and verification to the
212 server when performing the SKE. This was missing and the
213 remote server's (or router's) public key was accepted without
214 checking whether we have it previously or trust it at all.
215 Affected file silcd/protocol.c.
217 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Check in the silc_server_timeout_remote if protocol is active
220 and make sure that the protocol's final callback is called so
221 that all memory if freed. Affected file silcd/server.c.
223 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * silc_server_whois_send_reply crashed the server if the nickname
226 was 127 characters long. Affected file silcd/command.c.
228 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Added sanity check to the silc_server_new_client. If the hostname
231 is provided inside username then check that the provided hostname
232 really is the same as the resolved one. If the hostname was not
233 resolved then check it from the public key. Affected file is
234 silcd/packet_receive.c.
236 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
237 if the server disconnected us and the connection is not valid
238 anymore. Affected file irssi/src/silc/core/silc-channels.c.
240 * Moved the silc_client_[chmode|chumode|chumode_char] away from
241 the library to the lib/silcutil/silcutil.[ch].
243 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Close log file after open. Affected file
246 lib/silcutil/silclog.c.
248 * Check whether sock == NULL in silc_client_send_packet and return
249 if it is. Affected file lib/silcclient/silcclient.c.
251 * Check rec->entry == NULL in the Irssi SILC Client before
252 sending the channel message. Affecte file is
253 irssi/src/silc/core/silc-servers.c.
255 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
257 * Merged a splitted window bugfix from Irssi CVS tree. The
258 affected file is irssi/src/fe-text/textbuffer-view.c.
260 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
261 It did not print nickname.
263 * Improved the distributions system a bit.
265 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
268 irssi/src/fe-text/gui-window.c.
270 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
271 to in-active server. The affected file is
272 irssi/src/silc/core/client_ops.c.
274 * Resolve the client in USERS command reply if the entry does
275 not have username resolved. The affected file is
276 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
277 command to WHOIS command to really resolve stuff. The USERS
278 is not used any more in any critical section so WHOIS can
279 be used even though it might be slower than IDENTIFY.
281 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
284 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Changed the protocol API a bit more consistent in the
287 lib/silccore/silcprotocol.[ch].
289 * Changed the following headers to ROBODoc format:
291 lib/silccore/silcpayload.h
292 lib/silccore/silcprotocol.h
293 lib/silccore/silcsockconn.h
295 All core library headers are now formatted.
297 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
299 * Fixed a bug in Irssi SILC client; do not show that you are
300 server/router operator if you really are not. Affected file is
301 irssi/src/silc/core/client_ops.c.
303 * Renamed silc_command_free_payload to silc_command_payload_free.
304 Affected file lib/silccore/silccommand.h
306 * Added silcmath.h to include the prototoypes of various routines
307 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
310 * Changed the following headers to ROBODoc format:
312 lib/silccore/silcchannel.h
313 lib/silccore/silccommand.h
314 lib/silccore/silcid.h
315 lib/silccore/silcidcache.h
316 lib/silccore/silcmode.h
317 lib/silccore/silcnotify.h
318 lib/silccore/silcpacket.h
319 lib/silcmath/silcmath.h
321 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Added checking to the server code not to start the server if
324 ciphers and stuff are not configured properly. Affected files
325 silcd/serverconfig.[h] and silcd/server.c.
327 * Changed the layout of the header files of the public interfaces
328 in the SILC libraries. The new layout supports ROBODoc
329 documentation tool (and some others) so that it is easy to create
330 a library reference manual. All the other headers and source
331 code must still follow the CodingStyle document. Also source
332 code must not include these ROBODoc stuffs, only the headers.
333 Furthermore, all public interface headers must now be named
334 by using `silc' prefix, example: silcapi.h, silccipher.h.
335 Some files were renamed due to this. All the other headers
336 must not be used as public interfaces. I will update the
337 CodingStyle document later. Changed following headers, so far:
339 lib/silcclient/silcapi.h
340 lib/silccore/silcauth.h
341 lib/silccore/silcprivate.h
342 lib/silccrypt/silcdh.h
344 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Removed silc_client_packet_send_flush from the client library
349 as it is not needed. Affected file lib/silcclient/client.[ch].
351 * Added printing of message of unresolved authentication method
352 to the Irssi SILC client. Added it to the module formats.
353 Removed the same message from the client library.
355 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Added new distribution feature, DISTLABEL. Every distribution
358 can define own preprocessor label that can be used in the
359 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
360 file distributions, acconfig.h.pre and prepare.
362 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Added Makefile.defines_int to include the actual definitions
365 for Makefile.defines.in. Tested the new distribution system,
366 created distributions and tested installation.
368 * Added AWAY message printing to the Irssi SILC client. Added
369 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
371 * Added SCONNECT command to call the SILC's CONNECT command.
372 Cannot use CONNECT directly since Irssi uses that internally.
373 Affected file irssi/src/silc/core/silc-servers.c.
375 Added ACTION local command. It is same as ME command but takes
376 the channel as mandatory argument.
378 Rewrote some of the Irssi's help files to suite for SILC
381 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Added Makefile.defines[.in] that should for now on be included
384 in all Makefile.am file in the source tree. That file includes
385 all common compilation definitions for SILC source tree.
387 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Minor changes to the ./prepare script to change the package
390 name according the distribution name to the configure.in.
392 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Created new distribution system. Added file `distributions'
395 that defines all the distributions that can be created out of
396 the SILC source tree. The ./prepare script now reads that
397 file to determine how to prepare the distributions. The
398 first argument to the ./prepare is the name of the distribution
399 and second is the version of the distribution. If given
400 without arguments it creates the default (toolkit) distribution
401 with the default version (defined in ./prepare).
403 All Makefile.am files that are subject to the distributions
404 are now named as Makefile.am.pre. These are ./Makefile.am
405 and lib/Makefile.am. Others may be changed later.
407 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
409 * Added invite list, ban list, some key management and connection
410 error message printing to module formats in the Irssi SILC client.
412 * Added new silc_client_set_away_message to set the away message
413 that is back to the person who sent private message. The
414 affected file lib/silcclient/silcapi.h and the
415 lib/silcclient/client_prvmsg.c.
417 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * Fixed the private message sending in the Irssi SILC client,
420 added local command KEY to the Irssi SILC client.
422 Added key management and key agreement message formats to the
423 irssi/src/fe-common/silc/module-formats.[ch].
425 Added USERS (alias WHO) printing, server/router operator
426 indication and LIST command printing to the module formats.
428 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Fixed channel joining notify handling, cumode notify handling
431 from Irssi SILC client.
433 * Added SILC specific module-formats to the Irssi SILC client so
434 that SILC specific message hilighting, colors etc is possible.
435 Affected file irssi/src/fe-common/silc/module-formats.[ch].
437 Added channel mode, channel user mode, actions, notices,
438 whois and whowas printing to the the module-formats.c.
440 * Fixed a bug in channel deletion in the server. The channel
441 is not left to the cache even if the channel founder auth mode
442 is set when there are no users anymore on the channel. Affected
445 * The silc_net_localhost now resolves the entire hostname including
446 the domain name. Affected file lib/silcutil/silcnet.c.
448 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Changed the ask_passphrase client operation to be ascynchronous.
451 It has now a completion callback and a context that the
452 application must call after it has got the passphrase from
453 the user. Affected files lib/silcclient/silcapi.h,
454 lib/silcclient/protocol.c, lib/silcclient/command.c and
457 Added SilcAskPassphrase callback that the application calls
458 to deliver the passphrase to the library.
460 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
461 The public key verification and especially a certificate
462 verification is asynchronous procedure.
464 Added new SILC_SKE_STATUS_PENDING status to indicate the
465 request is pending and a callback will be called to finalize
468 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
469 indicate that remote end did not send its public key (or
470 certificate), even though we require it. Added check for this
471 condition in the SKE. This was a security bug, now fixed.
473 Defined new SilcSKEVerifyCbCompletion callback that is called
474 when the verification process is completed.
476 The affected files lib/silcske/silcske_status.h and
477 lib/silcske/silcske.[ch].
479 * Changed the verify_public_key client operation to be async
480 as well. Defined SilcVerifyPublicKey callback that is used to
481 indicate the success of the public key verification process.
483 Changed the server and client to use the new async client
486 * Changed the Irssi SILC client's internal scheduler to be called
487 twice as many times as it used to be. As a result the client
488 should be a bit faster now. Affected file is
489 irssi/src/silc/core/silc-core.c.
491 * Added support to Irssi SILC client of asynchronous public key
492 verification and passphrase inquiry. Affected file is
493 irssi/src/silc/core/silc-core.c.
495 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Do not say "You have left channel %s" in client library.
498 Moved it to the application. Affected files are
499 lib/silcclient/command.c and silc/client_ops.c.
501 * Fixed silc_client_get_clients. Command context was not
502 duplicated and was freed memory in the callback. Affected
503 file lib/silcclient/idlist.c.
505 * Do not say "you are now talking..." on JOIN command in the
506 client library. The appliation must handle it.
508 * Do not say ".. changed topic to" in command reply in the
509 client libary. The application must handle it.
511 * Fixed TOPIC command sending in the client library.
513 * Fixed a memory leak in silc_client_command_free in the file
514 lib/silcclient/command.c.
516 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * Imported a modified version of Irssi client to the source tree.
519 The Irssi will be used to create a new client called
520 Irssi SILC. Imported to irssi/.
522 Added silc_core_init_finish function to the Irssi. Affected
523 file irssi/configure.in.
525 A lot changes in the Makefile.ams around the irssi tree.
527 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
529 * Do not rehash if the new size is same as the old size of the
530 hash table, in the silc_hash_table_rehash*. The affected file
531 lib/silcutil/silchashtable.c.
533 * Replaced hash_table_del_by_context calls from the server
534 (when channel->user_list and client->channels) to the
535 hash_table_del as it is sufficient and faster.
537 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
539 * Added silc_hash_table_list, silc_hash_table_get and the
540 SilcHashTableList structure to provide an alternative way to
541 traverse the hash table. The affected files are
542 lib/silcutil/silchashtable.[ch].
544 * Changed the server's idlist routines to use the hash table
545 routines to optimize the code.
547 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Replaced the client entry's `channel' list and channel entry's
550 `user_list' list to hash tables for optimized lookup. Changed
551 the code to use the hash table interface around the code.
552 Affected file lib/silcd/idlist.[ch].
554 * Added `auto_rehash' boolean argument to the function
555 silc_hash_table_alloc to indicate whether the hash table should
556 auto-rehash when it thinks is appropriate time. It will
557 increase the hash table size if the there is twice as much
558 entries in the table than the size of the table, and will
559 decrease the size if there are twice as less entries than
560 the size of the table.
562 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Fixed silc_xxx_get_supported to not crash at some circumstances.
566 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * silc_idcache_purge_by_context deletes the entry now by context
569 as it is supposed to do. Affected file lib/silccore/idcache.c.
571 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
572 client is not anymore valid (WHOWAS givens the info) and not
573 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
575 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Removed the `data' and `data_len' arguments from the ID Cache
578 interfaces and added `name' argument. ID Cache does not handle
579 anymore the binary data only a names associated with given ID.
581 * When hashing a Client ID with silc_hash_id the entire ID is
582 not hashed anymore, instead only the hash of the Client ID is
583 hashed. This way we can access the Client ID from the cache
584 with Client ID but with the hash of the ID (which is a hash of
585 the nickname) as well without any difference in performance.
587 Added also silc_idcache_find_by_id_one_ext to do one on one
588 searching when we have the actual ID. Added also function
589 silc_hash_client_id_compare. The affected files are
590 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
592 * When hashing the name associated with a ID it is always done
593 in lowercase. This way we can access the cache without worrying
594 about case-sensitivity, even though, for example nicknames are
597 * Fixed a bug in server with channel message sending. It put
598 wrong ID type as destination ID. The affected file
601 * silc_idcache_del_by_context now deletes from all hash tables
602 by context. Affected file lib/silccore/idcache.c.
604 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Changed the client library to use the new ID Cache interface.
607 Changes around the source tree.
609 * Added silc_hash_table_rehash_ext to rehash with specific
610 hash function. Affected file lib/silcutil/silchashtable.[ch].
612 * Added silc_hash_string_compare to compare two strings in the
613 hash table. Affected file lib/silcutil/silcutil.[ch].
615 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
617 * Added new function silc_idcache_del_by_context into the
618 lib/silccore/idcache.[ch].
620 * Changed the server's ID list routines to use the new ID Cache
621 interface. Changes around the source tree.
623 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Added silc_hash_table_del[_by_context]_ext functions in to the
626 lib/silcutil/silchashtable.[ch].
628 Removed silc_hash_table_find_all* routines and added new
629 silc_hash_table_find_foreach to replace them.
631 Added silc_hash_table_replace_ext function as extended
632 replacing function. Separated the simple hash table interface
633 from the extended hash table interface in the file
634 lib/silcutil/silchashtable.h.
636 * Fixed minor bugs and changed it to use some of the new
637 hash table functions in lib/silccore/idcache.c
639 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Added new function silc_hash_table_find_all to return all keys
642 in the hash table by the specified key. As the hash table is
643 collision resistant it also makes it possible to have several
644 duplicate keys in the hash table. This function may be used to
645 find all of the keys from the hash.
647 Added user_context arguments to the SilcHashFunction,
648 SilcHashCompare and SilcHashDestructor to deliver user specified
651 Added new fuctions silc_hash_table_find[_all]_ext to do
652 extended lookup with specified hash and compare functions and
653 specified user contexts.
655 Added new function silc_hash_table_add_ext to add the key
656 with specified hash function and user context.
658 Added new function silc_hash_table_foreach to traverse all
659 entrys in the hash table. Added SilcHashForeach callback
662 Added new function silc_hash_table_del_by_context to delete
663 the entry only if the context associated with the key matches.
665 Affected files are lib/silcutil/silchashtable.[ch].
667 * Removed silc_hash_[server/client/channel]_id and added just
668 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
669 silc_hash_id_compare to compare two ID's using as the hash table
670 comparison function. Added also silc_hash_data to hash
671 binary data and silc_hash_data_compare to compare it.
673 * Removed silc_idlist_find_client_by_hash as it is not needed
674 anymore. Affected file silcd/idlist.[ch].
676 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
677 to use internally the SilcHashTable. The new ID Cache is a lot
678 faster than the old one. Some of the ID Cache interface was also
679 rewritten and obsolete and stupid functions were removed.
681 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Added entry_count field to the SilcHashTable to keep the number
684 of the entries in the table. Implemented the function
685 silc_hash_table_rehash. Added new function
686 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
688 Fixed a minor bug in silc_hash_table_free.
690 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
691 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
692 into the lib/silcutil/silcutil.[ch].
694 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
696 * Implemented a collision resistant hash table into the
697 lib/silcutil/silchashtable[ch]. See the header and the source
698 for the SilcHashTable API.
700 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Merged dotconf version 1.0.2 into lib/dotconf.
704 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Do not compile anything in lib/silcsim/* if the SIM support
707 is not enabled. The tree should now compile without problems
710 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Compiled the SILC under cygwin. Compiled and tested briefly
713 without problems. More tests needed. The SIMs didn't compile
716 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
718 * Fixed possible crash in silc_get_username in the
719 lib/silcutil/silcutil.c.
721 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
723 * Fixed a va_arg in silc/client_ops.c.
725 * Oops, RC5 routines were named AES and caused some problems
726 when not using SIM's. Affected file lib/silccrypt/rc5.c.
728 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Added new SilcIDIP structure into the lib/silccore/id.h and
731 replaced the old `ip' fields from all SILC ID's to that type.
732 This is a step towards IPv6 support.
734 The silc_id_get_len takes now the ID as an extra argument.
735 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
736 both IPv4 and IPv6 based ID's.
738 The affected files are lib/silccore/id.[ch] and other files
739 around the tree using these routines.
741 * Removed the ID length arguments in server from various
742 silc_server_send_notify_* routines -> they are not needed
745 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Fixed memory leak in silc_encode_pem_file in the file
748 lib/silcutil/silcutil.c.
750 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Check minor version as well in the SKE. Affected files are
753 silcd/protocol.c and lib/silcclient/protocol.c.
755 * Added --identifier option to the server so that an identifier
756 can be when creating the public key for the server. Affected
757 file is silcd/silcd.c.
759 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
760 lib/silccrypt/silcpkcs.c.
762 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Register default ciphers and stuff when using -C option with
765 the server. Affected file sildc/silcd.c.
767 * Put back the servers public key filename format, it is better
768 than the new one. For now, the client keys are saved with the
769 new filename format. The affected file silc/client_ops.c.
771 * Implemented the Cipher API for the rest of the ciphers that
772 did not implement it or implemented it the wrong way.
774 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Register default ciphers and stuff when using the -S option
777 in the client. Affected file silc/silc.c. Same also when
778 creating new key pair with -C option.
780 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Fixed the silc_verify_public_key client operation function to
783 save the public keys differently. The fingerprint is now
784 used as filename and not the hostname. This way also the
785 client keys are saved uniquely and not with hostnames. The
786 affected file is silc/client_ops.c.
788 * Trimmed the silc_hash_fingerprint function to remove extra
789 whitespaces from the end of the fingerprint. The affected
790 file is lib/silccrypt/silchash.c.
794 * Added silc_cipher_register_default function to register all
795 default ciphers. It can be used when configuration files
796 does not exist and the application does not want any specific
797 ciphers in any specific order.
799 The SilcDList is now used as silc_cipher_list dynamically
800 allocated cipher list. Removed the static list all together
801 and now all ciphers must be allocated to the dynamic list.
802 The silc_cipher_alloc routine was changed to check only the
805 All silc_cipher_* routines that used to return int returns
808 The affected files lib/silccrypt/silccrypt.[ch].
810 * The same thing was done to silc_hash_* as for silc_cipher_*
811 routines. Affected files lib/silccrypt/silchash.[ch].
813 * The same thing was done to silc_pkcs_* as for silc_cipher_*
814 routines. Affected files lib/silccrypt/silcpkcs.[ch].
815 Added also silc_pkcs_[un]register[_default] functions.
816 Removed the data_context from the PKCS API.
818 * Added silc_hmac_register_default function to register default
819 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
820 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
821 to unregister all hmacs at once.
823 * Register the default ciphers, hash functions, PKCSs and HMACs
824 if client's configuration file does not exist. The affected
827 * The client did not load the hash functions from the SIM
828 modules at all. Added support for this. Affected file is
831 * When decoding public key with silc_pkcs_public_key_decode, check
832 the supported algorithm only if PKCS are registered. Affected
833 file lib/silccrypt/silcpkcs.c. The same was done with the
834 silc_pkcs_private_key_decode.
836 * Fixed the SILC List routines to keep the list always in order.
837 It used to change the list's order when traversing the list but
838 not it preserves the order. Affected file lib/trq/silclist.h.
840 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
842 * Added the client library to use the SilcSocketConnection's
843 reference counter (by silc_socket_dup) to prevent the bug that
844 the socket object may be freed underneath async operation.
846 * The name resolv library checking fixes in the configure.in.pre.
849 * Created new version of the protocol drafts for future
850 development. The -03 drafts are the ones that will be changed
851 in the trunk now and the -02 will remain as they are.
853 * Send list of CUMODE notifys to the router when announcing
854 the channel users to the router. Affected file silcd/server.c.
855 If the router receiving channel founder CUMODE for a channel
856 that already has channel founder it will send CUMODE notify
857 to the sender to remove the channel founder rights from the
858 announced client. Affected file silcd/packet_receive.c.
860 * The CUMODE notify may now use Server ID as well as the entity
861 who changes the mode. Updated protocool specs.
863 * Updated INSTALL and README files.
865 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * New web pages in the http://silc.pspt.fi. The pages was
872 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Implemented the [DenyConnectin] config section in the server.
875 Added silc_server_config_denied_conn to check whether incoming
876 connection is denied. Affected file silcd/serverconfig.[ch].
878 * Do not check the ports when checking the incoming configuration
879 data if the port is 0, meaning any. Affected file is
880 silcd/serverconfig.c.
882 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Fixed buffer overflow in silc_string_compare in the file
885 lib/silcutil/silcutil.c.
887 * Fixed double free in silc_server_command_leave in the file
890 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * Fixed the version checking in the server. Affected file is
895 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
897 * Fixed the configuration data fetching when accepting new
898 connections in the server. Affected file silcd/server.c.
900 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
902 * Added `sender_entry' argument to the function
903 silc_server_packet_relay_to_channel so that we can check
904 whether some destination actually belongs to the same route
905 the sender belongs (ie, we must not resend the packet to the
906 sender). Affected file silcd/packet_send.[ch].
908 * Added `servername' field to the SilcClientEntry in the server
909 to hold the name of the server where client is from. Affected
910 file is silcd/idlist.h.
912 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Moved the channel message encrypting in the router betwen
915 router connections from silc_server_channel_message to the
916 silc_server_packet_relay_to_channel since we want to check
917 whether we have anybody channel before encrypting anything.
918 Affected files silcd/packet_[receive/send].c.
920 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Fixed the [AdminConnection] server config section to support
923 multiple entries. Affected file silcd/serverconfig.c.
925 * Added support into the server to check the validity of the
926 incoming connection before executing any KE or authentication
929 * The connection configuration is now saved to the KE and
930 connection auth protocol contexts and not fetched anymore in
931 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
933 * The local hosts listenning address and port is also resolved
934 now when starting the server. We want to have the socket object
935 to include the real address and port for the listener. Added
936 new function silc_net_check_local_by_sock into the files
937 lib/silcutil/silcnet.[ch].
939 * Fixed a broadcast bug in server -> do not broadcast if we
942 * Fixed a routing bug. Do not route broadcast packets ever.
943 Broadcast packets must be processed always and not routed since
944 they may be destined to some other host than yourself and thus
945 would get routed without no good reason. Affected file is
948 * Added function silc_server_config_is_primary_route to check
949 whether primary router connection has been configured (a router
950 configuration that we are initiating). If there is not, we
951 will assume that there is only two routers in the SILC network
952 and we will use the incoming router connection as our primary
953 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
955 * Changed the order of the broadcasting. Broadcast _after_ the
956 packet has been processed not before. Affected file is
959 * Fixed a [ClientConnection] parsing bug. The port was never
960 parsed correctly thus resulting to port 0. Affected file
961 silcd/serverconfig.c.
963 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
964 argument and did not set the broadcast packet flag. Affected
965 file silcd/packet_send.c. Fixed same bug in the function
966 silc_server_send_notify as well.
968 * If we receive NEW_ID packet for our own ID in the server, ignore
971 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
975 * Removed the nickname from the Private Message Payload.
976 Updated the code and the protocol specs.
978 * Updated protocol specs for submitting to the IETF.
980 * Tweaked the Random Number Generator a bit. Affected file
981 lib/silccrypt/silcrng.c. Exported a new function
982 silc_rng_[global]_add_noise which can be used to add more
985 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Do not parse packets with different timeout when protocol
988 is active -> may cause problem with rekey. Affected file
991 * When server receives signoff notify it must not create
992 new channel key if the client is on any channels since the
993 sender of the signoff notify will create it.
995 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Added printing of error messages during SKE protocol from the
998 failure packet sent by server during SKE. Affected file
1001 * Removed the client's failure_callback handling with timeout
1002 and handle it immediately when received.
1004 * The SKE library returned wrong type in SUCCESS and FAILURE
1005 packets. They must be 32 bit MSB not 16 bit MSB.
1007 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Ok, rewrote the logic of the re-key and now it seems to work.
1010 I tested it on high traffic with frequent re-keys without
1011 problems. Added hmac_receive (and renamed hmac to hmac_send)
1012 in SilcClientConnection in lib/silcclient/client.h and
1013 in SilcIDListData in silcd/idlist.h. Also, removed the
1014 SilcPacketParserContext's cipher and hmac fields as they are
1015 not needed anymore and actually caused some problems when
1016 the ciphers and hmac's changed underneath the packet parser.
1018 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * If re-key protocol is active then process the incoming packets
1021 synchronously since we must assure that icoming packets encrypted
1022 with the old key is processed before the new keys is set to
1023 use. This is true other packets than for REKEY packets.
1024 Affected file silcd/server.c. The same was done to client library
1025 as well, affected file lib/silcclient/client.c.
1027 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Fixed bug in client and server to accept the force send if
1030 the packet is send from silc_[server/client]_packet_process
1031 function. Otherwise the packets are never delivered, oops.
1033 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Disable force sending of packets when REKEY protocol is active.
1036 We must assure that no packet is sent directly when rekey is
1037 performed. All packets must be sent through packet queue.
1038 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1039 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1040 function is silc_[server/client]_packet_send_real to check
1043 * Replaced the SIM paths from example config files to
1044 /usr/local/modules. Also, make install creates now
1045 /usr/local/silc/logs directory to hold all the SILC server
1048 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Made the configure.in.pre work on Solaris. Patch by salo.
1052 * Made all ciphers compatible with non-x86 machines. Defined
1053 CBC mode macros into lib/silccrypt/ciphers_def.h.
1055 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Fixed the make install.
1059 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * When MAC computation fails the silc_packet_decrypt returned 0
1062 even though it was supposed to return -1. Fixed this. The
1063 affected file is lib/silccore/silcpacket.c.
1065 * Do not replace the config files in /etc/silc (in make install)
1066 if they already exist. Affected file ./Makefile.am.
1068 * Do not send re-key packets immediately but through packet queue.
1069 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1071 * Changed silc_net_check_host_by_sock to return FALSE if the
1072 IP/DNS could not be resolved. Though, it returns the IP address
1073 now even if it could not resolve it (but returns also FALSE).
1074 Affected file lib/silcutil/silcnet.[ch].
1076 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1078 * Added silc_pkcs_decode_identifier to decode the public key's
1079 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1080 Added also silc_pkcs_free_identifier. Added also new context
1081 SilcPublicKeyIdentifier.
1083 * Added -S option to the silc client. It is used to dump the
1084 contents of the specified public key file.
1086 * Changed the PKCS api to return the public key length when
1087 setting the public key.
1089 * Fixed a fatal bug in the public and private key file loading.
1090 Affected file lib/silccrypt/silcpkcs.c.
1092 * Execute the packet parsing for client with zero (0) timeout
1093 if the protocol is active. Affected file silcd/server.c.
1095 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1097 * Made the key generation options to the silcd program. Added
1098 -C option, equivalent to client's option.
1100 * Added new [ServerKeys] config section to the server. It
1101 configures the server's public and private key.
1103 * Defined generic Public Key Payload into the protocol
1104 specification to send specific type of public keys and
1107 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1108 public key or certificate.
1110 * Implemented the GETKEY command to the server and to the

1115 * Made preliminary `make install' work.
1117 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1119 * Added SilcServerRekey context into silcd/idlist.h.
1121 * Added the PFS support as defined in the specification to the
1122 SKE protocol. Affected files lib/silcske/*.c.
1124 * Added `ske_group' field to the SilcServerRekey context to hold
1125 the number of the SKE group that is used with PFS in re-key.
1126 Affected file silcd/idlist.h.
1128 * Added PFS re-key support to the server. Affected file is
1131 * Added silc_protocol_cancel to cancel execution of the next
1132 state of the protocol. Affected file is
1133 lib/silccore/silcprotocol.[ch].
1135 * Added the re-key support with and without PFS to the client
1136 library. Re-key is performed once in an hour, by default.
1138 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1139 Added silc_client_rekey_callback and silc_client_rekey_final.
1140 Affected files are lib/silcclient/protocol.[ch] and
1141 lib/silcclient/client.[ch].
1143 * Removed the `hmac_key' and `hmac_key_len' fields from the
1144 SilcClientConnection structure; not needed. Affected file is
1145 lib/silcclient/client.h.
1149 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Do not ask whether user wants to use the negotiated private key
1152 for private messages, just use it. Affected file is
1153 silc/local_command.c.
1155 * Added `send_enc_key' and `enc_key_len' fields to the
1156 SilcIDListData structure since they are needed in the re-key
1157 phase. Affected file is silcd/idlist.[ch].
1159 * Implemented the simple re-key protocol into the server.
1160 Affected files silcd/server.c and silcd/protocol.[ch]. The
1161 re-key will be performed once in an hour, by default.
1163 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1164 Added silc_server_rekey, silc_server_rekey_callback and
1165 silc_server_rekey_final.
1167 * Removed Tunneled flag from the protocol. Updated the code
1168 and the specifications.
1170 * Adde `pfs' field to the SilcIDListData to indicate whether
1171 the PFS is to be performed in the re-key. Affected file is
1174 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1177 int64 of at least the xintXX size. If void * is less that 4
1178 bytes uint32 * will be used. Defined bool as boolean.
1180 * Changed _ALL_ unsigned long and unsigned int to uint32,
1181 unsgined short to uint16 in the source tree.
1183 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1184 not handle clients that has entry->data.registered == FALSE.
1185 They are not in the network anymore. Affected file is
1188 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1190 * Implemented the sending of the SERVER_SIGNOFF notify in the
1191 server. Affected file is silcd/server.c.
1193 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1194 Added also silc_notify_payload_encode_args into the
1195 lib/silccore/silcnotify.[ch].
1197 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1198 Affected file silcd/packet_receive.c.
1200 * Implemented the SERVER_SIGNOFF notify handling in the client
1201 library. Affected file lib/silcclient/client_notify.c. Also,
1202 implemnted the printing of the SERVER_SIGNOFF info to the
1203 application. Affected file silc/client_ops.c.
1205 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1206 if the deleting was successful. Affected file silcd/idlist.[ch].
1208 * Added support for public key authentication in the connection
1209 authentication protocol in the client library. Affected file
1210 lib/silcclient/protocol.c.
1212 * Changed the server's silc_idlist_get_clients_by_* interface
1213 to support already allocated array so that new entries may be
1214 added to pre-allocated array. Affected file silcd/idlist.[ch].
1215 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1216 and command replies.
1218 * All command reply functions in the server now calls the
1219 pending command callback even if error occured. This way the
1220 error will be delivered to the client as well. Affected files
1221 silcd/command.c and silcd/command_reply.c.
1223 * Fixed INFO command to return local server's info if no server
1224 was provided. Affected file lib/silcclient/command.c.
1226 * Removed RESTART command for good. Updated the code and the
1229 * Rewrote parts of the task system. It is a bit simpler now.
1230 Removed unsued task priorities. The affected files are
1231 lib/silcutil/silctask.[ch].
1233 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Moved the USERS printing from the library to the application.
1236 Affected files lib/silcclient/command.c and silc/client_ops.c.
1238 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Added channel key re-key support. The re-key is perfomed
1243 only by the router and is done once in an hour. Added `rekey'
1244 field to the SilcChannelEntry in the server. Affected files
1245 silcd/server.c and silcd/idlist.h.
1247 * Added silc_task_unregister_by_context into the file
1248 lib/silcutil/silctask.[ch].
1250 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Added SILC_UMODE_GONE mode to indicate when the client is not
1253 present in the SILC network. Added also support to the local
1254 command AWAY that will set this mode. Added support of showing
1255 "xxx is gone" in WHOIS command. The USERS command shows the
1256 gone status as well.
1258 * Fixed setting server and router operator privileges in the
1259 server's UMODE command. Affected file silcd/command.c.
1261 * Merged the SKE KE1 and KE2 payloads into one payload. The
1262 new KE payload is equivalent to the old KE2 payload.
1264 Cleaned up the SKE Start Payload parsing. It now uses the
1265 simple buffer unformatting to do the parsing. A lot faster
1268 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1269 to the SKE that is used to indicate whether both of the SKE
1270 parties should perform authentication. By default only the
1271 responder performs authentication. By setting this flag also
1272 the initiator must do authentication. By default it is unset
1273 since in normal SKE case, client to server connection, only
1274 the responder should do authentication. When doing SKE between
1275 two clients both should perform authentication. Updated the
1276 code and the protocol specs.
1278 * A little fix to IDENTIFY command in the server. Search the
1279 client first by hash not nickname. Affected file is
1282 * Fixed the silc_client_close_connection to support closing
1283 the client to client connections wihtout deleting too much
1284 data. Affected file lib/silcclient/client.c.
1286 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1287 are received if protocol used to be active but is not anymore
1288 the application would crash due to NULL pointer dereference.
1289 Affected files silcd/server.c and lib/silcclient/client.c.
1291 * Added `hash' field to the SilcClientConnection to include
1292 the hash function negotiated in the SKE protocol.
1294 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1295 to set the channel founder authentication data. A client can
1296 claim the founder rights later by providing the authentication
1297 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1298 This way the channel founder can regain the channel founder
1299 privileges even it is left the channel. This works only on
1300 local server and the client must be connected to the same
1301 server to be able to regain the founder rights. Updated the
1302 protocol specs accordingly.
1304 Added support to the CMODE command in the client to set the
1305 founder auth data. Read the README to see how to set it.
1307 Added support to the CUMODE command to claim the founder
1308 rights. Read the README to see how to do it.
1310 Added support for the founder authentication to the Channel
1311 Entry in the server. Affected file silcd/idlist.h.
1313 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1314 server's CMODE command. Affected file silcd/command.c.
1316 * Added the following new functions into lib/silccore/silcauth.[ch]:
1317 silc_auth_get_method and silc_auth_get_data.
1319 * The server now saves the remote hosts public key to the
1320 SilcIDListData pointer. Affected file silcd/protocol.c.
1322 * The normal server now does not remove the channel entry from
1323 the cache if the founder authentication data is set. It used
1324 to remove it if the founder was the last one on the channel on
1325 the server and left the channel. The auth data is saved and
1326 if the channel is re-joined later the old entry is used with
1327 the old auth data. Affected files silcd/command_reply.c and
1330 * Removed the `pkcs' field from the SilcIDListData structure
1331 in the server; it is not used. Affected file silcd/idlist.h.
1333 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Fixed packet processing on slow links. Partial packets were
1336 never re-processed because the incoming data buffer was cleared
1337 by the application. Application must not directly clear the
1338 sock->inbuf, the packet processing routines handle it. Fixed
1339 this in client library and in server.
1341 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Fixed the WHOIS and IDENTIFY send reply function to really
1344 check whether to send list or just one entry. Affected file
1347 * Cleaned up the LEAVE command's channel key distribution. The
1348 affected file silcd/command.c.
1350 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1351 can enforce the channel mode as well. In that case the ID
1352 includes the ID of the server. The code now enforces the
1353 mode change if the router have different mode than the server.
1355 * The notify client operation with CMODE_CHANGE notify can now
1356 return NULL client_entry pointer if the CMODE was not changed
1357 by client. Application must check for this.
1359 * Added <Server ID> argument to INFO command to support server
1360 info fetching by Server ID.
1362 * Added silc_server_announce_get_channel_users to get assembled
1363 packets of channel users of the specified channel. Affected
1364 file silcd/server.[ch].
1366 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1367 was freed underneath the ID Cache.
1369 * Re-announce clients when the server received CHANNEL_CHANGE
1370 notify from the router. Affected file silcd/packet_send.c.
1372 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1375 crashed since it did not handle the fact that there is no cipher
1376 called "3" and didn't check the error condition. Now fixed.
1378 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1379 flag. It can be used to send message requests.
1381 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Implemented the RESTART command in the client.
1385 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1386 notice type messages. Added notice printing to the user
1389 * The channel keys are not re-generated if the channel's mode
1390 is PRIVKEY, ie private key on the channel exists. Affected
1391 files silcd/server.c and silcd/command.c.
1393 * Fixed a little bug in channel message delivery when channel
1394 private keys are set in the server. Affected file is
1395 silcd/packet_send.c.
1397 * Changed the setting on channel->on_channel = TRUE from the
1398 silc_client_save_channel_key to the JOIN command reply. The
1399 key payload is not received if the private channel key is set.
1400 Affected file lib/silcclient/command_reply.c and the
1401 lib/silcclient/client_channel.c.
1403 * When the CMODE_CHANGE notify is sent and the channel private
1404 key mode is removed the channel key must be re-generated in
1405 other cells as well. Added this support for the router in the
1406 silcd/packet_receive.c.
1408 * Added new local command NOTICE to send notice message on
1409 channel. Affected file silc/local_command.[ch].
1411 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Added new local command ME to the client. It is used to send
1414 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1415 some action. Affected file silc/local_command.[ch].
1417 * Changed channel_message and private_message client operations
1418 to deliver the message flags to the application. Added also
1419 the `flags' arguments to the silc_client_send_channel_message
1420 and silc_client_send_private_message functions. Affected file
1423 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Redefined the Private Message Payload to support private message
1426 keys and to support the new private message flags. Updated
1427 the protocol specs. Flags makes it possible to have for example
1428 CTCP style messages.
1430 * Added new type SilcPrivateMessagePayload and defined an API
1431 for it in the lib/silcclient/silcprivate.[ch].
1433 * Tested private message private keys successfully. Tested the
1434 private message key set, unset and list commands with the new
1437 * Redefined the Channel Message Payload to include the channel
1438 message flags (equal with private message flags) to support
1439 for example CTCP style messages.
1441 * Defined some of the message (for channel and private message)
1442 flags. Updated the protocol specs and added the flags to the
1443 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1445 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1447 * Added SilcKeyAgreementStatus type to the key agreement routines
1448 to indicate the current status and error if one occured.
1449 The status types are defined in the lib/silcclient/silcapi.h.
1451 * Added new local command KEY that is used to set and unset private
1452 keys for channels, set and unset private keys for private messages
1453 with remote clients and to send key agreement requests and
1454 negotiate the key agreement protocol with remote client. The
1455 key agreement is supported only to negotiate private message keys,
1456 it currently cannot be used to negotiate private keys for channels,
1457 as it is not convenient for that purpose.
1459 * Fixed a minor pending callback setting bug in the function
1460 silc_client_get_client_by_id_resolve, now the function works.
1461 Affected file lib/silcclient/idlist.c.
1463 * Added function silc_net_get_local_port to get local bound
1464 port by socket. Added to lib/silcutil/silcnet.[ch].
1466 * Added `sockets' and `sockets_count' fields to the SilcClient
1467 object. They hold the sockets of the listenning sockets in
1468 the client. Listenning sockets may be for example the key
1469 agreement server. Affected file lib/silcclient/client.[ch].
1470 Added functions the silc_client_add_socket and the
1471 silc_client_del_socket. They are exported to the application
1474 * Added ~./silc/clientkeys to support other client's public keys.
1476 * Renamed verify_server_key client operation to verify_public_key
1477 and added one argument to indicate the type of the connection
1478 (server, client etc.).
1480 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Added silc_server_connection_auth_request to handle the
1483 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1484 silcd/packet_receive.[ch].
1486 * Added silc_server_send_connection_auth_request into the
1487 silcd/packet_send.c to send the connection auth request packet.
1489 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1492 * Fixed the public key authentication in responder side in the
1493 server. The `auth_data' pointer includes the SilcPublicKey
1494 not the path to the public key. Affected file silcd/protocol.c.
1496 * Implemented the public key authentication in the initiator side
1497 in the server. Affected file silcd/protocol.c.
1499 * Removed the [RedirectClient] config section from the server
1500 configuration. Is not needed and I don't want to implement it.
1502 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1504 * Cleaned up the CMODE command in the server. It now works
1505 correctly and supports all the modes defined in the protocol.
1506 Affected file is silcd/command.c.
1508 * Added `hmac_name' field to the SilcChannelEntry in the server
1509 to hold the default HMAC of the channel. It can be set when
1510 creating the channel (with JOIN command). Affected files
1513 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1514 type to indicate the change of the current cipher and hmac
1515 on the channel. Client can safely ignore the <cipher> argument
1516 (if it chooses to do so) since the CHANNEL_KEY packet will
1517 force the channel key change anyway. The <hmac> argument is
1518 important since the client is responsible of setting the new
1519 HMAC and the hmac key into use.
1521 * Fixed the CMODE command in the client library as well.
1523 * Tested CMODE command in router environment successfully.
1525 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Show the version of the remote client (or server) when connecting
1528 to the server. It is logged to the log file. Affected file
1529 is silcd/protocol.c.
1531 * Fixed the KILLED notify handling in the client library. The
1532 client must be removed from all channels when receiving the
1535 Also, do not remove the client entry when giving the KILL
1536 command but when the KILLED notify is received.
1538 * Removed silc_idlist_find_client_by_nickname from the server.
1539 Not needed anymore. Affected files silcd/idlist.[ch].
1541 * Implemented the CHANNEL_CHANGE notify type handling to the
1542 server. Affected file silcd/server.c.
1546 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1548 * Added silc_server_send_notify_invite to send the INVITE
1549 notify between routers.
1551 * Implemented the INVITE command correctly to the server.
1553 * Implemented the INVITE notify type handling in the server.
1555 * Implemented the INVITE command to the client library and on the
1558 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1560 * Added function silc_server_get_client_resolve to find the
1561 client entry by ID from all ID lists and then resolve it
1562 (using WHOIS) if it cannot be found. Affected file is
1565 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Implemented the BAN command to the client library.
1569 * The JOIN command in the server now checks the invite list
1572 * Changed the silc_command_reply_payload_encode_va and the
1573 silc_command_payload_encode_va to support that if argument is
1574 NULL it ignores and checks the next argument. Affected file
1575 lib/silccore/silccommand.c.
1577 * Added silc_server_send_notify_ban to send the BAN notify
1578 type between routers.
1580 * Chaned the silc_notify_payload_encode to support that if
1581 argument is NULL it ignores and checks the next argument.
1582 Affected file lib/silccore/silcnotify.c.
1584 * Tested ban lists in router environment successfully.
1586 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Implemented BAN command to the server, in silcd/command.[ch].
1590 * Removed the BAN and INVITE_LIST modes from the CMODE command
1593 * Added function silc_string_match to regex match two strings.
1594 Affected files lib/silcutil/silcutil.[ch].
1596 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Redefined parts of the SilcChannelEntry in the server to support
1599 the new ban and invite lists.
1601 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Redefined the INVITE command. The same command can be used to
1604 invite individuals to the channel but also to manage the invite
1605 list of the channel (to add to and remove from the invite list).
1606 Updated the protocol specs.
1608 * Added new command SILC_COMMAND_BAN that can be used to manage
1609 the ban list of the channel. Updated the protocol specs.
1611 * Removed the channel modes: the SILC_CMODE_BAN and the
1612 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1613 in the CMODE command. The equivalent features are now available
1614 using INVITE and BAN commands. Updated the protocol specs.
1616 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1617 in the network about change in the current ban list. The notify
1618 type is not used by the client.
1620 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1621 support the invite lists.
1623 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1625 * Added new function silc_string_regexify that converts string
1626 including wildcard characters into regex string that can
1627 be used by the GNU regex library. Added into the file
1628 lib/silcutil/silcutil.[ch].
1630 Added silc_string_regex_combine to combine to regex strings
1631 into one so that they can be used as one regex string by
1632 the GNU regex library. Added into the file
1633 lib/silcutil/silcutil.[ch].
1635 Added silc_string_regex_match to match two strings. It returns
1636 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1638 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Imported GNU regex to the soruce tree into lib/contrib.
1641 Fixed some compiler warning from the regex.c.
1643 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Fixed MOTD command in the server to work in router environment.
1647 * Fixed the MOTD command in the client library to support
1648 the server argument in the command.
1650 * Added `nickname_len' argument to the silc_idlist_add_client
1651 in the server, as the `nickname' argument may be binary data
1654 * Added silc_idlist_get_channels to return all channels from
1657 * Implemented LIST command to the server. Affected file is
1660 * Implemented the LIST command to the client library and on the
1663 * Added [<user count>] argument to the LIST command reply.
1664 With private channels the user count is not shown.
1666 * Updated TODO and README.
1668 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * The client entry's data.registered must be TRUE even with
1671 global client entry on global client list. The data.registered
1672 is used to check whether the client is anymore in the network,
1673 for example with WHOWAS command so it must be valid.
1675 * Fixed the WHOWAS command in the server. It now actually works
1676 in router environment. Added function into silcd/command_reply.c
1677 silc_server_command_reply_whowas_save.
1679 * Added silc_idlist_purge function to the silcd/idlist.c
1680 to periodically purge the ID Cache.
1682 * Fixed INFO command in the server. It works now in router
1683 environment. Added <server name> argument to the INFO command
1684 reply. Updated the protocol specs.
1686 * Fixed minor bug in silc_idcache_purge to not purge if the
1687 expire value is zero.
1689 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1690 they were buggy because of the WHOWAS information.
1692 * Fixed local command MSG to handle the async resolving of
1693 the remote client properly. It used to fail the first MSG.
1694 Affected file silc/local_command.c.
1696 * Added `data_len' field to SilcIDCache context.
1698 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Update TODO. Todo in commands in the server.
1702 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1704 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1705 used by routers as broadcast packet to inform other routers
1706 about the changed user mode.
1708 Implemented the notify handling in the server. Affected file is
1709 silcd/packet_receive.c. Added the function
1710 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1712 * Added new generic Channel Payload and deprecated the New Channel
1713 Payload. The New Channel Payload is now the generic Channel
1716 * Added new argument `mode' to the silc_server_send_new_channel
1717 as it is required in the Channel Payload now.
1719 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1720 and created a new and real SilChannelPayload to represent the
1721 new generic Channel Payload. Implemented the encode/decode
1722 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1724 * Added silc_server_get_client_channel_list to return the list
1725 of channels the client has joined for WHOIS command reply.
1726 Affected file silcd/server.[ch].
1728 * Implemented the channel list sending in the WHOIS command reply
1729 in server and in the client.
1731 Implemented the channel list displaying on the user interface
1732 as well. Affected file silc/client_ops.c.
1734 * Added silc_channel_payload_parse_list to parse list of Channel
1735 Payloads. It returns SilcDList list of SilcChannelPayloads.
1736 Client for example can use this function to parse the list of
1737 channels it receives in the WHOIS command reply. The caller
1738 must free the list by calling silc_channel_payload_list_free.
1739 Affected files lib/silccore/silcchannel.[ch].
1741 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Added one new argument <user mode> to the WHOIS command reply
1744 to return the mode of the user in SILC. Updated the protocol
1747 Implemented it to the server and client.
1749 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Fixed the mode printing on the user interface on joining.
1752 Affected file silc/client_ops.c.
1754 * Implemented the UMODE command and user modes in general to the
1755 client library and to the user interface.
1757 * Implemented the UMODE command to the server.
1759 * The server now sends UNKNOWN_COMMAND error status if client sends
1760 unknown command. Affected file silcd/command.c.
1762 * All server commands now handle the command identifier the right
1763 way when sending the command reply to the client. The client can
1764 use to identify the command replies with the identifier.
1766 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1768 * Added silc_server_get_client_route to resolve the route to
1769 the client indicated by the client ID. Affected file is
1772 * Added silc_server_relay_packet as general function to relay
1773 packet to arbitrary destination. This deprecates functions
1774 like _send_private_message_key, _relay_notify etc. Affected
1775 file is silcd/packet_send.[ch].
1777 Removed silc_server_send_key_agreement,
1778 silc_server_send_private_message_key and
1779 silc_server_packet_relay_notify functions from the file
1780 silcd/packet_send.[ch].
1784 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1785 server. Affected file silcd/packet_receive.[ch].
1787 * Implemented the KILL command to the client. Implemented the
1788 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1789 Affected files lib/silcclient/command[_reply].c and
1790 lib/silcclient/client_notify.c. Implemented the KILL notify
1791 printing in the user inteface.
1793 * Fixed a lot silc_parse_nick memory leaks from the client
1794 library in the file lib/silcclient/command.c.
1796 * Changed the silc_server_send_notify_on_channels's `sender'
1797 argument from SilcSocketConnection to SilcClientEntry to
1798 check the sender as entry and not as connection object and not
1799 to send to the client provided as argument. The affected file
1800 is silcd/packet_send.[ch].
1802 * The notify packets that are destined directly to the client used
1803 to not to be processed by the server. Now changed that and the
1804 server processes all notify packets. After relaying the packet
1805 to the client the notify packet is processed in the server.
1807 * The silc_server_free_client_data now checks whether there is
1808 pending outgoing traffic for the client and purges the data to
1809 the network before removing the client entry.
1811 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1814 an client is killed from the SILC Network. Updated the protocol
1817 Added new function silc_server_send_notify_killed to the
1818 silcd/packet_send.[ch].
1820 * Added function silc_server_packet_relay_notify to relay notify
1821 packets that are destined directly to a client. In this case
1822 the server does not process the notify packets but merely relays
1823 it to the client. Affected file silcd/packet_send.[ch].
1825 Added also silc_server_packet_process_relay_notify to check
1826 whereto relay the notify. Affected file is
1827 silcd/packet_receive.[ch].
1829 * Implemented the KILL command to the server.
1833 * Added the backup schema desgined last fall to the protocol
1834 specs for everyone to see. The specification is in the
1835 *-spec-xx.txt draft and the packet type definitions for the
1836 backup routers is in *-pp-xx.txt draft. Thusly, added also
1837 new packet type SILC_PACKET_CELL_ROUTERS.
1839 * A big security problem in the implementation discovered. The
1840 signoff of an client did not cause new channel key generation
1841 which it of course should've done. The channel keys must be
1842 always re-generated when client leaves (or signoffs) the channel.
1843 The silc_server_remove_from_channels funtion now handles
1844 the channel key re-generation.
1846 * Added `sender' argument to the silc_server_send_notify_on_channels
1847 to not to send the client provided as argument. Affected file
1848 silcd/packet_send.[ch].
1850 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Implemented OPER and SILCOPER commands into the server and
1855 * Added silc_auth_verify and silc_auth_verify_data to verify
1856 the authentication directly from the authentication payload.
1857 It supports verifying both passphrase and public key based
1858 authentication. Affected file lib/silccore/silcauth.[ch].
1860 * Added `hash' field to the SilcIDListData structure. It is the
1861 hash negotiated in the SKE protocol. Affected file is
1864 * Slight redesigning of the SilcAuthPayload handling routines.
1865 Do not send SilcPKCS but SilcPublicKey as argument.
1867 * Implemented the public key authentication support to the
1868 serverconfig. The public key is loaded from the provided path
1869 and saved as authentication data to void * pointer. Thus,
1870 changed the unsigned char *auth_data to void *auth_data;
1872 * Fixed SHUTDOWN command to send the reply before the server
1873 is shutdown. :) Affected file silcd/command.c.
1875 * Fixed fatal bug in CONNECT command. The hostname was invalid
1876 memory and server crashed. Affected file silcd/command.c.
1878 * Fixed fatal bug in CLOSE command. The server_entry became
1879 invalid but was referenced later in the command. Affected file
1882 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1884 * Fixed fatal bug in failure packet handling. Server ignored
1885 the failure and thus crashed when it came.
1889 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1891 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1892 that the command may be executed only once in (about) 2 seconds.
1893 The old SILC_CF_LAG flag is same but allows command bursts up
1894 to five before limiting.
1896 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1897 server code. Various commands now includes the CF_LAG_STRICT
1898 flag to disallow any kind of miss-use of the command.
1900 * Fixed the silc_buffer_unformat to not to allocate any data
1901 if the length of the data is zero. It used to allocate the
1902 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1904 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1906 * Changed the format of AdminConnection configuration section
1907 in the server. Added username of the admin to the format.
1908 Affected files silcd/serverconfig.[ch].
1910 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1911 to return admin configuration data by host, username and/or
1914 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Implemented WHOWAS command to the server. Added the functions:
1918 silc_server_command_whowas_parse,
1919 silc_server_command_whowas_send_reply,
1920 silc_server_command_whowas_from_client and
1921 silc_server_command_whowas_from_server
1923 * Added <Client ID> argument to the WHOWAS command reply. Updated
1924 the protocol specs accordingly.
1926 * Implemented WHOWAS command and command_reply to the client
1929 Implemented the WHOWAS printing on the user interface.
1931 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Added new argument to the WHOWAS command reply, the real name.
1934 It is an optional argument. Updated the protocol specs.
1936 * Added SilcIDCacheDestructor callback that is registered when
1937 the SilcIDCache is allocated. The callback is called when
1938 an cache entry in the ID Cache expires, or is purged from the
1939 cache. Added into lib/silccore/idcache.[ch].
1941 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1942 to destruct the client entries when the cache entry expires.
1943 Other ID Cache's in server and in the client library ignores
1946 * If the ID Cache entry's `expire' field is zero then the entry
1947 never expires. Added boolean `expire' argument to the
1948 silc_idcache_add function in the lib/silccore/idcache.[ch].
1949 If it is TRUE the default expiry value is used.
1951 * Added silc_server_free_client_data_timeout that is registered
1952 when client disconnects. By default for 5 minutes we preserve
1953 the client entry for history - for WHOWAS command.
1955 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Added support to the server to enforce that commands are not
1958 executed more than once in 2 seconds. If server receives
1959 commands from client more frequently, timeout is registered
1960 to process the commands. Affected file silcd/command.c.
1961 Added new function silc_server_command_process_timeout.
1963 * Changed NICK_NOTIFY handling in client library to check that
1964 if the client's nickname was changed, so there is no need to
1965 resolve anything from the server.
1967 * Removed error printing from the WHOIS and IDENTIFY commands.
1968 If error occurs then it is ignored silently in the client library.
1969 The application, however, may map the received error to
1970 human readable error string. The application currently maps
1971 the NO_SUCH_NICKNAME error to string.
1973 * Made the command status message public to the application. Moved
1974 them from lib/silcclient/command_reply.c to
1975 lib/silcclient/command_reply.h. The application can map the
1976 received command status to the string with the
1977 silc_client_command_status_message function.
1979 * Added check to the server to check that client's ID is same
1980 as the Source ID in the packet the client sent. They must
1983 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Added dist-bzip hook to the Makefile.am to make bzip2
1986 compressed distributions.
1988 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Server now enforces the maximum length for the nickname and
1991 the channel as protocol specification dictates. 128 bytes for
1992 nickname and 256 bytes for channel name.
1994 * Moved the WHOIS printing to the application. The client libary
1995 does not print out the WHOIS information anymore, the application
1996 must do it. Renamed silc_client_command_reply_whois_print to
1997 the silc_client_command_reply_whois_save.
1999 The client's idle time is also sent to the application now, and
2000 the idle is shown on screen.
2002 * Added silc_client_command_reply_identify_save to save the
2003 received IDENTIFY entries.
2005 * Do not check for channel private keys in message sending and
2006 reception if the channel does not have the PRIVKEY mode set.
2007 Affected file lib/silclient/client_channel.c.
2009 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2012 just surfaced after chaning the JOIN procedure.
2014 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Added silc_client_get_clients_by_list to get client entries
2017 from Client ID list, that is returned for example by JOIN
2018 and USERS command replies. The application should use this
2019 function for example when JOIN command reply is received to
2020 resolve the clients already on the channel (library does not
2021 do that anymore as USERS command reply is not used in the JOIN
2022 procedure anymore). Affected files lib/silcclient/silcapi.h and
2023 lib/silcclient/idlist.c.
2025 * JOIN command reply and USERS command reply returns now SilcBuffer
2026 pointers instead of unsigned char pointers when returning
2027 the client list and mode list.
2029 * Added <Client ID> argument to the JOIN command reply, mainly
2030 for the server to identify for which client the command was
2031 originally sent. Updated protocol specs accordingly.
2033 * Added SilcDlist private_key pointer to the SilcChannelEntry
2034 in the client to support the channel private keys. Affected
2035 file is lib/silcclient/idlist.h.
2037 * Added SilcChannelPrivateKey argument to the function
2038 silc_client_send_channel_message so that application can choose
2039 to use specific private ke if it wants to. If it is not provided,
2040 the normal channel key is used, unless private keys are set.
2041 In this case the first (key that was added first) is used
2042 as the encryption key.
2044 * Implemented the support for channel private key handling.
2045 Implemented the following functions:
2047 silc_client_add_channel_private_key,
2048 silc_client_del_channel_private_keys,
2049 silc_client_del_channel_private_key,
2050 silc_client_list_channel_private_keys and
2051 silc_client_free_channel_private_keys
2053 Affected file lib/silcclient/client_channel.c.
2055 * Added the support for the private keys in the channel message
2056 sending and encryption and in the message reception and
2057 decryption. Affected funtions are
2058 silc_client_send_channel_message and silc_client_channel_message.
2060 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2062 * Added SKE's key verify callback to the client library's
2063 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2065 * Removed the statement that server (or router) must send USERS
2066 command reply when joining to the channel so that the client
2067 knows who are on the channel. Instead, the client list and
2068 client's mode list is now sent in the JOIN command reply to the
2069 client who joined channel. This is better solution.
2071 * Added function silc_server_get_users_on_channel and function
2072 silc_server_save_users_on_channel to the silcd/server.[ch].
2074 * Removed function silc_server_command_send_users from the
2077 * Do not show topic on the client library anymore. The topic is
2078 sent in the command reply notify to the application and the
2079 application must show the topic now.
2081 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Added client searching by nickname hash into the IDENTIFY and
2084 WHOIS commands in the server as they were clearly missing from
2085 them. Affected file is silcd/command.c.
2087 * Fixed a bug in private message receiving in the client library.
2088 The remote ID was freed and it wasn't supposed, now it is
2091 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Minor fix to the channel payload; allocate the data area, as it
2094 needs to be of specific length.
2096 * If the key agreement port is zero then the operating
2097 system will define the bound port. Affected files are
2098 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2100 * Added new function silc_channel_payload_decrypt into the file
2101 lib/silccore/silcchannel.[ch].
2103 * Moved the channel message etc, check from silc_packet_decrypt
2104 to applications. The library calls now a generic
2105 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2106 when the packet is either normal or special. This was done to
2107 allow more wide range of checking that was not allowed when
2108 the code was in library. Now applications can do virtually any
2109 checks to the packet and return to the library the decision how
2110 the packet should be processed. Affected files are
2111 lib/silccore/silcpacket.[ch].
2113 Added silc_server_packet_decrypt_check to the server and
2114 silc_client_packet_decrypt_check to the client library.
2116 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2117 to send with specified source and destination information.
2119 * Channel message delivery between routers was broken after the
2120 channel key distribution was fixed earlier. The channel key
2121 was used be to distributed to other routers as well which is not
2122 allowed by the protocol. Now this is fixed and channel keys
2123 really are cell specific and the channel message delivery between
2124 routers comply with the protocol specification.
2126 * Fixed various commands in server to check also the global list
2127 for the channel entry and not just the local list. The affected
2128 file silcd/command.c.
2130 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Added assert()s to buffer formatting and unformatting routines
2133 to assert (if --enable-debug) when error occurs. Affected
2134 file: lib/silcutil/silcbuffmt.c.
2136 * Changed to auto-reconnect to check whether the remote host is
2137 router and register the re-connect timeout if it is. It used
2138 to check that whether we are normal server, but router must do
2139 auto-reconnect with another router as well. Affected file
2142 * Removed the [<key len>] option from CMODE command as the cipher
2143 name decides the key length, nowadays. See the defined ciphers
2144 from the protocol specification.
2146 * Added [<hmac>] option to the CMODE command to define the HMAC
2147 for the channel. Added SILC_CMODE_HMAC channel mode.
2149 * Added [<hmac>] option for the JOIN command so that user can
2150 select which HMAC is used to compute the MACs of the channel
2153 * Added Hmac field to the Channel Message Payload. The integrity
2154 of plaintext channel messages are now protected by computing
2155 MAC of the message and attaching the MAC to the payload. The
2156 MAC is encrypted. Now, it is clear that this causes some
2157 overhead to the size of the packet but rationale for this is that
2158 now the receiver can verify whether the channel message decrypted
2159 correctly and also when private keys are set for the channel the
2160 receiver can decrypt the packet with several keys and check from
2161 the MAC which key decrypted the message correctly.
2163 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2164 lib/silccrypt/silccipher.[ch].
2166 * Added silc_hash_len to return the digest length into the
2167 lib/silcrypt/silchash.[ch].
2169 * Rewrote parts of Silc Channel Payload interface in the
2170 lib/silccore/silcchannel.[ch]. The encode function now also
2171 encrypts the packet and parse function decrypts it.
2173 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Fixed a minor formatting bug in the SKE's key material processing.
2176 It actually might have processed the keys wrong way resulting
2179 * Redefined the mandatory HMAC algorithms and added new algorithms.
2180 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2181 and hmac-md5 truncated to 96 bits. The mandatory is now
2182 hmac-sha1-96. Rest are optional (including the one that used
2183 to be mandatory). Rationale for this is that the truncated HMAC
2184 length is sufficient from security point of view and can actually
2185 make the attack against the HMAC harder. Also, the truncated
2186 HMAC causes less overhead to the packets. See the RFC2104 for
2189 * Added new [hmac] configuration section. The SKE used to use
2190 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2191 is of course wrong. The official names that must be proposed in
2192 the SKE are the ones defined in the protocol specification
2193 (hmac-sha1-96 for example). The user can configure any hmac
2194 using any hash function configured in the [hash] section. At
2195 least, the mandatory must be configured.
2197 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2199 * Added HMAC list to the SKE proposal list. It has now both
2200 hash algorithm list and HMAC list. This makes the protocol
2201 incompatible with previous versions. The SKE now seems to work
2202 the way it is supposed to work, for the first time actually.
2204 * Defined plain Hash algorithms to the protocol specification.
2207 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2209 * Implemented support for key agreement packets into the server.
2210 Added functions silc_server_key_agreement and
2211 silc_server_send_key_agreement. Other than these functions,
2212 server has nothing to do with this packet.
2214 * Added support for private message key packets into the server.
2215 Added functions silc_server_private_message_key and
2216 silc_server_send_private_message_key.
2220 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2221 called in the protocol's final callback instead in the END
2222 protocol state. This makes a little more sense and in the same
2223 time in client we can use the same protocol routines for normal
2224 key exchange and to key agreement packet handling as well.
2226 * Added to both client's and server's KE protocol context the
2227 SilcSKEKeyMaterial pointer to save the key material. We will
2228 bring the key material to the protocol's final callback by doing
2229 this. The final callback must free the key material.
2231 * Added SKE's packet_send callback into client's KE protocol
2232 context so that the caller can choose what packet sending function
2233 is used. This way we can use different packet sending when
2234 doing normal SKE when doing key agreement packet handling (in
2235 the key agreement packet handling we do not want to encrypt
2238 * Implemented the responder side of the key agreement routines
2239 in the client. The client can now bind to specified port and
2240 accept incoming key negotiation. The key material is passed
2241 to the application after the protocol is over.
2243 * Implemented the processing of incoming Key Agreement packet
2244 in the client. Added function silc_client_key_agreement to
2247 * Implemented the intiator side of the key agreement routines
2248 in the client. The client can now initiate key agreement with
2249 another remote client. The key material is passed to the
2250 application after the protocol is over.
2252 * Created client_keyagr.c to include all the key agreement
2255 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2256 SILC_TASK_CALLBACK except that it is not static.
2258 * Created client_notify.c and moved the Notify packet handling
2259 from the client.[ch] into that file.
2261 * Created client_prvmsg.c and moved all private message and
2262 private message key routines from the client.[ch] into that file.
2264 * Create client_channel.c and moved all channel message and
2265 channel private key routines from the client.[ch] into that file.
2267 * Changed silc_client_get_client_by_id_resolve to resolve with
2268 WHOIS command instead of IDENTIFY command, in the file
2269 lib/silclient/idlist.c.
2271 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Implemented the SKE's responder side to the Client library.
2275 * When FAILURE is received to the protocol do not trust it
2276 blindly. Register a timeout to wait whether the remote closes
2277 the connection as it should do it, only after that process the
2278 actual failure. This was changed to both client and server.
2280 * Added client_internal.h to include some of the structures
2281 there instead of client.h in lib/silcclient/.
2283 * Added function silc_task_unregister_by_callback to unregister
2284 timeouts by the callback function.
2286 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Some "Incomplete WHOIS info" errors has been appearing on the
2289 log files. Took away the entry->userinfo check from WHOIS
2290 reply sending. The entry->userinfo is now " " if client did not
2291 provide one. I thought this was fixed earlier but something
2292 is wrong still. Let's see if the error still appears.
2294 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Fixed a minor bug in the login when the channel key is
2297 re-generated in the server. It used to generate the key in
2298 wrong order and thus caused problems in the channel traffic.
2300 * Fixed a minor bug in channel key distsribution after
2301 KICK command. The key was not sent to the router even though
2304 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Added silc_ske_process_key_material_data as generic routine
2307 to process any key material as the SILC protocol dictates. The
2308 function is used by the actual SKE library but can be used by
2309 applications as well. This relates to the private message keys
2310 and the channel private keys since they must be processed the
2311 same way the normal SILC session keys. The protocol dictates
2312 this. Affected files: lib/silcske/silcske.[ch].
2314 Added also silc_ske_free_key_material to free the
2315 SilcSKEKeyMaterial structure.
2317 * Defined silc_cipher_set_key function to set the key for
2318 cipher without using the object's method function. The affected
2319 files: lib/silccrypt/silccipher.[ch].
2321 * Implemented silc silc_client_add_private_message_key,
2322 silc_client_add_private_message_key_ske,
2323 silc_client_del_private_message_key,
2324 silc_client_list_private_message_keys and
2325 silc_client_free_private_message_keys functions in the
2328 Added functions silc_client_send_private_message_key to send
2329 the Private Message Key payload and silc_client_private_message_key
2330 to handle incoming Private Message Key payload.
2332 * Added Cipher field to the Private Message Key payload to set
2333 the cipher to be used. If ignored, the default cipher defined
2334 in the SILC protocol (aes-256-cbc) is used.
2336 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Removed lib/silcclient/ops.h file.
2340 Redefined parts of the SILC Client Library API. Created new
2341 file silcapi.h that deprecates the ops.h file and defines the
2342 published Client Library API. Defined also private message key
2343 API and channel private key API into the file.
2345 This is the file that the application must include from the
2346 SILC Client Library. Other files need not be included by
2347 the application anymore.
2349 * Added new key_agreement client operation callback and also
2350 defined the Key Agreement library API for the application.
2352 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2355 is used by clients to request key negotiation between another
2356 client in the SILC network. If the negotiation is started it
2357 is performed using the SKE protocol. The result of the
2358 negotiation, the secret key material, can be used for example
2359 as private message key.
2361 Implemented the Key Agreement payload into the files
2362 lib/silccore/silauth.[ch].
2364 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Redefined ciphers for the SILC protocol. Added some new ciphers
2367 and defined the key lengths for the algorithms. Changed the
2368 code accordingly. The default key length is now 256 bits.
2370 * Fixed SKE key distribution function silc_ske_process_key_material
2371 when the key length is more than 128 bits. The default key
2372 length in SILC is now 256 bits.
2374 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2375 to indicate unsupported algorithm.
2377 * Renamed rijndael.c to aes.c and all functions as well.
2379 * Fixed a long standing channel key setting bug in client library.
2380 Weird that it has never surfaced before.
2382 * Fixed bug in channel deletion. If the entire channel is removed
2383 then it must also delete the references of the channel entry
2384 from the client's channel list as the client's channel entry and
2385 the channel's client entry share same memory.
2387 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Implemented CONNECT and SHUTDOWN commands in the client.
2391 * Implemented CLOSE command to the client.
2393 * Added the function silc_idlist_find_server_by_name into the
2394 files silcd/idlist.[ch].
2396 Added the function silc_idlist_find_server_by_conn into the
2397 files silcd/idlist.[ch].
2399 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * DIE command was renamed to SHUTDOWN. Updated the both code
2404 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2405 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2407 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2410 * Added function silc_server_create_connection function to create
2411 connection to remote router. My server implementation actually
2412 does not allow router to connect to normal server (it expects
2413 that normal server always initiates the connection to the router)
2414 so the CONNECT command is only good for connecting to another
2417 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2420 or some other client was kicked from the channel.
2422 Implemented the handling of the notify type to both client
2425 Implemented silc_server_send_notify_kicked to send the KICKED
2426 notify. It is used to send it to the server's primary router.
2428 * Implemented the KICK command into server and client.
2430 * Added `query' argument to the silc_idlist_get_client function
2431 to indicate whether to query the client from server or not if
2434 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2435 to indicate that the client is not channel founder.
2439 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Removed the rng context from SilcPacketContext structure and
2442 changed that the packet routine uses the Global RNG API.
2444 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Added support for quit message that client can "leave" on the
2447 channel when it quits the SILC. It is ditributed inside the
2448 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2450 Added silc_server_free_client_data that will take the
2451 signoff message as argument.
2453 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2455 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Updated parts of the protocol specification to keep it up
2460 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2463 payloads in one packet.
2465 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2466 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2467 use now the new List flag.
2469 * Also deprecated the following packet types: REPLACE_ID,
2470 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2472 * Added list support for Notify packet in server.
2474 * Added silc_server_send_notify_channel_change to send the
2475 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2476 the silc_server_send_replace_id.
2478 * Added silc_server_send_notify_nick_change to send the
2479 NICK_CHANGE notify type. Deprecates the function
2480 silc_server_send_replace_id.
2482 * Added silc_server_send_notify_join to send the JOIN notify type.
2483 Deprecates the function silc_server_send_new_channel_user.
2485 * Added silc_server_send_notify_leave to send LEAVE notify type.
2486 Deprecates the function silc_server_send_remove_channel_user.
2488 * Added silc_server_send_notify_cmode and
2489 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2490 types. Deprecates the silc_server_send_set_mode function.
2492 * Added SERVER_SIGNOFF notify type to indicate that server has
2493 quit. This means that all clients on the channel from that
2494 server will drop. This can be also used when netsplit happens.
2496 Deprecated REMOVE_ID packet type since it is not needed anymore
2499 Added silc_server_send_notify_server_signoff to send the
2500 SERVER_SIGNOFF notify type. Deprecates the function
2501 silc_server_send_remove_id.
2503 Added also silc_server_send_notify_signoff to send the
2504 SIGNOFF notify type.
2506 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2507 SILC protocol from this day on. Changed the protocol
2508 specification as well.
2510 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2511 notify type. It is used between routers to notify about
2512 topic changes on a channel.
2514 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2517 * Partly updated the protocol specification to comply with the
2518 changes now made. It is still though a bit outdated.
2520 * The JOIN notify type now takes one extra argument <Channel ID>.
2521 The packet used to be destined to the channel but now the
2522 JOIN type may be sent as list thus it is impossible to
2523 destine it to any specific channel. By adding this argument
2524 it is again possible.
2526 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Added CREDITS file. The CHANGES and CREDITS file will appear
2529 in the distribution as well.
2531 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2533 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2534 types in the server's silcd/packet_receive.c.
2536 * Implemented CMODE and CUMODE to work in router environment.
2538 * Fixed minor encoding and decoding buglet from the
2539 lib/silccore/silcmode.c.
2541 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2544 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2546 * Changed all SilcConfigServer* and silc_config_server* to
2547 SilcServerConfig* and silc_server_config*, respectively.
2550 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Associated the ID (client or server ID) to the Authentication
2553 Payload to avoid any possibility of forging. Updated the
2554 protocol specification and the code accordingly.
2556 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * The RSA key length is now save to the RsaKey context in the
2559 key generation process in lib/silccrypt/rsa.c. The key length
2560 is now used to figure out the maximum size of the block allowed
2561 to be encrypted/signed.
2563 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2564 is equivalent to the silc_mp_mp2bin but does not allocate any
2567 * Changed silc_mp_mp2bin API to take length argument. If it is
2568 non-zero then the buffer is allocated that large. If zero, then
2569 the size is approximated using silc_mp_sizeinbase, which however
2572 * Created Global RNG API which is global RNG that application can
2573 initialize. After initializing, any routine anywhere in the
2574 code (including library) can use RNG without allocating a new
2575 RNG object. This was done to allow this sort of use of the
2576 RNG in code that has no chance to allocate RNG object. All
2577 applications currently allocate this and many routines in the
2578 library use this. Affected file lib/silccrypt/silcrng.[ch].
2580 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2581 it to use the Global RNG API.
2583 * Defined Authentication Payload into protocol specification that
2584 is used during SILC session to authenticate entities. It is
2585 used for example by client to authenticate itself to the server
2586 to obtain server operator privileges.
2588 Implemented this payload into the lib/silccore/silcauth.[ch].
2589 Implemented also routines for public key based authentication
2590 as the new protocol specification dictates.
2592 Moved definitions of different authentication methods from
2593 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2595 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2596 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2597 silc_pkcs_verify_with_hash functions into the file
2598 lib/silccrypt/silcpkcs.[ch].
2600 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * The client entry's userinfo pointer must be always valid.
2603 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2604 will fail since it requires the userinfo. Now, the userinfo
2605 is allocated as "" if actual userinfo does not exist. Actually,
2606 it must exist and it is totally Ok to drop client connections
2607 that does not announce the userinfo. However, we will make
2608 this workaround for now.
2610 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2611 to return the remote port by socket.
2613 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2616 SILC_SERVER_PENDING_EXEC and added an new macro
2617 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2618 data or when error occurs while processing the pending command.
2620 Added new argument `destructor' into silc_server_command_pending
2621 and to the SilcServerCommandPending object. This destructor is
2622 now called after calling the pending callback or if error occurs
2623 immediately. If error occurs the actual pending callback won't
2624 be called at all - only the destructor. The destructor may be
2625 NULL if destructor is not needed.
2627 All this applies for client library code as well. Similar
2628 changes were made there as well for the pending commands.
2630 In the client, the application must now allocate the
2631 SilcClientCommandContext with the silc_client_command_alloc
2634 * Added reference counter to the SilcServerCommandContext. Added
2635 function silc_server_command_alloc and silc_server_command_dup
2638 Same type of functions added to the client library for the same
2641 * Removed the cmd_ident from IDListData away since it is now
2642 global for all connections. It is the command identifier used
2643 in command sending and with pending commands. The affected file
2646 * Added reference counter to the SilcSocketConnection objecet to
2647 indicate the usage count of the object. The object won't be
2648 freed untill the reference counter hits zero. Currently only
2649 server uses this, and client ignores it. The client must be
2650 set to use this too later. The affected files are
2651 lib/silccore/silcsockconn.[ch]. Added also the function
2652 silc_socket_dup to increase the reference counter.
2654 This was mainly added because it is possible that the socket
2655 is removed underneath of pending command or other async
2656 operation. Now it won't be free'd and proper DISCONNECTING
2657 flags, etc. can be set to avoid sending data to connection that
2658 is not valid anymore.
2660 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2661 the connection. After that it sets SILC_SET_DISCONNECTED.
2662 It is, however, possible that the socket data is not still freed.
2663 The silc_server_packet_process now checks that data is not
2664 read or written to connection that is DISCONNECTED. The socket
2665 get's freed when the reference counter hits zero.
2667 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Changed the client operation API: channel_message operation's
2670 `sender' is now the client entry of the sender, not the nickname
2671 and the `channel' is the channel entry, not the channel name.
2673 In the private_message operation the `sender' is now also the
2674 client entry of the sender not the nickname.
2676 Affected file is lib/silcclient/ops.h and all applications
2677 using the client operations.
2679 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Moved the calling of ops->connect() from connect_to_server_final
2682 into receive_new_id functin since that is the point when the
2683 client is actually allowed to send traffic to network. The
2684 affected file is lib/silcclient/client.c.
2686 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2689 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2690 (if needs broadcasting) instead of broadcasting the packets one
2691 by one which would make a burst in the network traffic.
2693 * Added `broadcast' argument to the functions in silcd/server.[ch]
2694 silc_server_create_new_channel[_with_id] to indicate whether
2695 to send New Channel packet to primary router.
2697 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added new function into the silcd/server.[ch] files:
2700 silc_server_create_new_channel_with_id to create new channel with
2701 already existing Channel ID.
2703 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2704 lib/silccore/silcpacket.h. This packet is used t send list of
2705 Set Mode payloads inside one packet. Server uses this to set
2706 the modes for the channels and clients on those channels, that it
2707 announced to the router when it connected to it. The protocol
2708 specification has been updated accordingly.
2710 * The silc_server_new_channel did not handle the packet coming
2711 from normal server as it normally does not send that. However,
2712 when it announces its channels it does send it. Implemented
2713 the support for that.
2715 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2716 into the file lib/silccore/id.h.
2718 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Fixed memory leaks in the functions silc_idlist_del_client,
2721 silc_idlist_del_channel and silc_idlist_del_server in the file
2722 silcd/idlist.c. All of those leaked like a sieve.
2724 * Fixed some small memory leaks in the client's function
2725 silc_client_notify_by_server.
2727 * Added functions into silcd/server.c: silc_server_announce_clients,
2728 silc_server_announce_channels and silc_server_announce_server.
2729 These functions are used by normal and router server to announce
2730 to its primary router about clients, channels and servers (when
2731 router) that we own. This is done after we've connected to the
2734 These functions effectively implements the following packet types:
2735 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2736 and SILC_PACKET_NEW_ID_LIST.
2738 * Added new functions into the silcd/packet_receive.[ch]:
2739 silc_server_new_id_list, silc_server_new_channel_list and
2740 silc_server_new_channel_user_list to handle the incoming
2741 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2743 * Added support of changing Channel ID in the function
2744 silc_server_replace_id. If the server that announces a channel
2745 to the router already exists in the router (with same name but
2746 with different Channel ID), router is responsible to send
2747 Replace ID packet to the server and force the server to change
2748 the Channel ID to the one router has.
2750 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2751 client that the Channel ID has been changed by the router. The
2752 normal server sends this to the client. Client must start using
2753 the new Channel ID as the channel's ID.
2755 Implemented handling of this new type into lib/silcclient/client.c
2756 into the function silc_client_notify_by_server.
2758 * Added new function silc_idlist_replace_channel_id into the files
2759 silcd/idlist.[ch] to replace the Channel ID.
2761 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Call silc_server_command_identify_check always when processing
2764 the IDENTIFY command in silcd/command.c
2766 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2769 send keepalive packets. The packet can be sent by clients,
2770 servers and routers.
2772 Added function silc_socket_set_heartbeat into the file
2773 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2774 If not set, the heartbeat is not performed. The actual
2775 heartbeat is implemented in the low level socket connection
2776 library. However, application is responsible of actually
2779 Added silc_server_send_heartbeat to send the actual heartbeat
2780 packet into silcd/packet_send.[ch]. Server now performs
2781 keepalive with all connections.
2783 * Added silc_task_get_first function into lib/silcutil/silctask.c
2784 to return the timeout task with shortest timeout. There was a bug
2785 in task unregistration that caused problems. TODO has been
2786 updated to include that task system must be rewritten.
2788 * The client library will now resolve the client information when
2789 receiving JOIN notify from server for client that we know but
2790 have incomplete information.
2792 * Rewrote parts of silc_server_remove_from_channels and
2793 silc_server_remove_from_one_channel as they did not remove the
2794 channel in some circumstances even though they should've.
2796 * Encryption problem encountered in server:
2798 The LEAVE command used to send the Channel Key packet to the
2799 router immediately after generating it. However, the code
2800 had earlier sent Remove Channel user packet but not immediately,
2801 ie. it was put to queue. The order of packets in the router
2802 was that Channel Key packet was first and Remove Channel User
2803 packet was second, even though they were encrypted in the
2804 reverse order. For this reason, MAC check failed. Now, this
2805 is fixed by not sending the Channel Key packet immediately but
2806 putting it to queue. However, this is more fundamental problem:
2807 packets that are in queue should actually not be encrypted
2808 because packets that are sent immediately gets encrypted
2809 actually with wrong IV (and thus MAC check fails). So, packets
2810 that are in queue should be encrypted when they are sent to
2811 the wire and not when they put to the queue.
2813 However, the problem is that the current system has not been
2814 designed to work that way. Instead, the packet is encrypted
2815 as soon as possible and left to the queue. The queue is then
2816 just purged into wire. There won't be any fixes for this
2817 any time soon. So, the current semantic for packet sending
2820 o If you send packet to remote host and do not force the send
2821 (the packet will be in queue) then all subsequent packets to the
2822 same remote host must also be put to the queue. Only after the
2823 queue has been purged is it safe again to force the packet
2826 o If you send all packets immediately then it safe to send
2827 any of subsequent packets through the queue, however, after
2828 the first packet is put to queue then any subsequent packets
2829 must also be put to the queue.
2831 Follow these rules and everything works fine.
2833 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Added new function silc_server_remove_clients_by_server to
2836 remove all client entries from ID list when the server connection
2837 is lost. In this case it is also important to invalidate all
2838 client entires as they hold the invalid server entry. This
2839 fixes fatal bug when server has lost connection and will reconnect
2842 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Made some sanity checks to silc_server_daemonise like to check
2845 whether the requested user and group actually exists.
2847 * Added sanity check to SKE's silc_ske_responder_finish to check
2848 that the public and private key actually is valid.
2850 * Invalidate the client's nickname when receiving Replace ID
2851 packet and the Client ID is being replaced. This means that the
2852 server will query the nickname if someone needs it (client)
2855 * Sort the ID Cache in client library when the ID Cache data
2856 has changed (needs sorting).
2858 * Do not allow for SILC client to create several connections to
2859 several servers. The client does not support windows right now
2860 and generating multiple connections causes weird behaviour.
2862 Irssi-silc client does support windows and can handle several
2863 connections without problems, see: www.irssi.org and SILC plugin.
2865 * Fixed some places where client was added to the IDList. The
2866 rule of thumb is following (in order to get everything right):
2867 If the client is directly connected local client then the
2868 `connection' argument must be set and `router' argument must be
2869 NULL to silc_idlist_add_client function. If the client is not
2870 directly connected client then the `router' argument must
2871 bet set and the `connection' argument must be NULL to the
2872 silc_idlist_add_client function.
2874 * The funtion silc_server_packet_send_local_channel actually did
2875 not check whether the client was locally connected or not. It
2876 does that now. Fixed a bug related to LEAVE command.
2878 * Fixed Remove Channel User payload parsing bug in server's
2879 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2881 * The server's silc_server_save_channel_key now checks also the
2882 global ID list for the channel as it might not be in the local
2883 list. Fixed a bug related to LEAVE command.
2885 * Is this the end of the [<unknown>] buglet that has been lurking
2886 around for a long time? A little for loop fix in server's
2887 silc_server_command_whois_parse that is used by both IDENTIFY
2888 and WHOIS command. At least, this was a clear bug and a cause
2889 of one type of [<unknown>] buglet.
2891 * WHOIS and IDENTIFY commands call the function
2892 silc_server_command_[whois/identify]_check function even if
2893 we are not router server.
2895 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Added --with-gmp configuration option. If set the GMP
2898 is always compiled in the SILC source tree. If not set then
2899 it is checked whether the system has the GMP3 installed. If
2900 it has then the GMP won't be compiled (the system's headers
2901 and library is used), if it doesn't have it then the GMP is
2902 compiled in the SILC source tree.
2904 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Changed RSA private exponent generation to what PKCS #1
2907 suggests. We try to find the smallest possible d by doing
2908 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2909 not security fix but optimization.
2911 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * Added new config entry [Identity] to fork the server and run
2914 it as specific user and group. A patch from Bostik.
2916 * Imported Dotconf configuration library into lib/dotconf.
2917 This will be used to create the SILC configuration files later.
2918 It will appear in the distsribution after this commit.
2920 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2922 * A big code auditing weekend happening. Auditing code for
2923 obvious mistakes, bugs and errors. Also, removing any code
2926 Removed files for being obsolete:
2928 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2929 inline in the file lib/silcutil/silcbuffer.h)
2931 o lib/silcutil/silcbufutil.c (the header has inline versions)
2933 Changed code to fix possible error conditions:
2935 o The buffer formatting routines now check that the destination
2936 buffer really has enough space to add the data. This applies for
2937 both buffer formatting and unformatting
2938 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2939 unformatting was changed to accomodate following rules:
2940 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2941 sent to the function while XXX_*STRING will not allocate or copy
2942 the data into the buffer. Instead it sets the pointer from the
2943 buffer into the pointer sent as argument (XXX_*STRING used to
2944 require that the pointer must be allocated already). This change
2945 makes this whole thing a bit more consistent and more optimized
2946 (note that the data returned in the unformatting with XXX_*STRING
2947 must not be freed now). The routines return now -1 on error.
2949 o Tried to find all code that use buffer_format and buffer_unformat
2950 and added return value checking to prevent formatting and
2951 especially unformatting errors and possible subsequent fatal
2954 o Changed ske->x and ske->KEY to mallocated pointers in
2955 lib/silcske/silcske.h. Fixed possible data and memory leak.
2957 o Added return value checking to all *_parse* functions. Fixed
2958 many memory leaks as well.
2960 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2961 so that buffer overflows would not happen. All code now also
2962 checks the return value as it can fail.
2964 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Added reconnection support to server if the normal server looses
2967 its connection to the router (for example if router is rebooted).
2968 The server performs normal reconnection strategy implemented
2969 to the server. Affected file silcd/server.c.
2971 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added new packet type SILC_PACKET_SET_MODE that is used to
2974 distribute the information about changed modes (for clients,
2975 channels and clients channel modes) to all routers in the
2976 network. Updated the protocol specification accordingly.
2978 Added functions into silcd/packet_send.c and
2979 silcd/packet_receive.c: silc_server_send_set_mode,
2980 silc_server_set_mode.
2982 Added new files silcmode.[ch] into lib/silccore that implements
2983 the encoding and decoding of Set Mode Payload. Added new type
2984 SilcSetModePayload. Moved the definitions of different modes
2985 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2987 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Oops, a little mistake in server's connection authentication
2990 protocol. The protocol is not ended with FAILURE but with
2991 SUCCESS if the authentication is Ok. :) Affected file is
2994 * Implemented NICK_CHANGE notify handling in server in the file
2995 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2996 the local clients on the channel. After the changing nickname
2997 in router environment snhould work and the [<unknown>] nickname
2998 should appear no more.
3000 The silc_server_replace_id function that receives the Replace ID
3001 payload now sends the NICK_CHANGE notify type also in the file
3002 silcd/packet_receive.c
3004 * Changed WHOIS and IDENTIFY command to support the maximum amount
3005 of arguments defined in protocol specs (3328 arguments). This
3006 fixed a bug that caused problems when there were more than three
3009 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Added extra parameter, command identifier, to the
3012 silc_client_send_command so that explicit command identifier
3015 Changed that ID list routines uses specific command identifier
3016 when sending WHOIS/IDENTIFY requests to the server so that they
3017 can be identified when the reply comes back.
3019 Affected files lib/silcclient/command.[ch],
3020 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3022 * Added `sender' argument to silc_server_packet_send_to_channel
3023 to indicaet the sender who originally sent the packet to us
3024 that we are now re-sending. Ignored if NULL. Affected file
3025 silcd/packet_send.[ch].
3027 * Added some server statistics support in silcd/server_internal.h
3028 SilcServerStatistics structure and around the server code. Also
3029 send some nice statistics information when client is connecting
3032 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Fixed channel ID decoding in server's JOIN command reply in
3035 silcd/command_reply.c
3037 * Fixed braodcasting of replace ID payload to not to send it if
3038 we are standalone server in silcd/packet_receive.c.
3040 * Fixed all channel message sending routines to not to send
3041 packets to clients that has router set, since they are routed
3042 separately in the same function earlier. Affects file
3043 silcd/packet_send.c and all channel packet sending functions.
3045 * In USERS reply, res_argv[i] are not allocated, the table
3046 is allocated. Thus changed that free the table, not its
3049 * In server's whois_check and identify_check if the client is
3050 locally connected do not send any WHOIS commands - they are not
3053 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Fixed some minor bugs in client when sending WHOIS command. The
3056 arguments was in wrong order.
3058 * Removed statis function add_to_channel from server in
3059 silcd/command.c that was previously used with the joining but
3062 * Tested USERS command in router environment successfully with two
3063 routers, two servers and two clients.
3065 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Reorganized the USERS command and command reply in client library
3068 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3069 When the command is given by user we register a pending command
3070 callback that will reprocess the command after the reply has been
3071 received from the server. When reprocessing the packet we then
3072 display the information. Thus, the USERS information is displayed
3073 now in the command callback instead of in the command reply
3074 callback. The processing of the command is same as previously
3075 when server has sent the command reply in the JOINing process.
3077 * Added to USERS command in silcd/command_reply.c to join the client,
3078 we didn't use to know about, to the channel after we've created
3079 a client entry for it. Also, for clienet we did know already still
3080 check whether it is on the channel or not and add it if not.
3082 * Removed silc_server_command_join_notify as the function and its
3085 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Changed the client's pending command handling to the same as the
3088 server's pending command handling. It is also now possible to
3089 execute command reply functions from other command reply
3090 function as the function callbacks for commands and command
3091 replies are one and same. The pending commands are not static
3092 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3093 in client connection context. Thus, pending commands are server
3094 connection specific as it is convenient.
3096 Changed the function silc_client_command_pending and
3097 silc_client_command_pending_del and added new function
3098 silc_client_command_pending_check. Removed the
3099 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3102 * Added cmd_ident, current command identifier, to the client
3103 connection context in lib/silcclient/client.h to keep track on
3104 command identifiers used in command sending. Client's command reply
3105 function handling now supports the mandatory command identifiers.
3107 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3108 funtions in client to fully support pending command callbacks.
3110 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3111 as one of the arguments to the application in the command reply
3114 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3115 before first releasing SILC but came back. Now it is removed again
3116 and should come back nomore. The FORWARDED flag was used only
3117 by the JOINing procedure by forwarding the command packet to router.
3118 Now, the JOINing procedure has been changed to more generic (due
3119 to various router environment issues) and FORWARDED is not needed
3120 anymore for anything. The protocol specification is yet to be
3123 Now, removed silc_server_packet_forward from server and the flag
3124 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3126 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Renamed NAMES command to USERS command. The NAMES was named that
3129 due to historical reasons. Now it is renamed. Also, rewrote
3130 parts of the USERS command. The nickname list is not sent anymore
3131 by the server. Only Client ID and mode lists are sent in the USERS
3132 command. Changed this also to the protocol specification.
3134 The client now resolves the names and stuff after it receives
3135 the USERS list from the server when joining to the channel.
3137 * WHOIS and IDENTIFY commands has been changed to support multiple
3138 Client ID's per command. One can now search for multiple users
3139 in the network by sending only one WHOIS or IDENTIFY command.
3140 Changed the code and the protocol specifications.
3142 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3143 uses silc_server_command_whois_parse to parse the request. */
3145 * If normal server, do not parse the WHOIS and IDENTIFY requests
3146 before sending it to the router. Saves some time.
3148 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Fixed JOIN command on client library. Wrong number of arguments
3151 used to crash the client.
3153 * Added silc_server_channel_has_global function to check whether
3154 channel has global users or not.
3156 * Added silc_server_channel_has_local function to check whether channel
3157 has locally connected clients on the channel.
3159 * The silc_server_remove_from_one_channel now checks whether the
3160 channel has global users or not after given client was removed from
3161 the channel. It also checks whether the channel has local clients
3162 on the channel anymore. If it does not have then the channel entry
3163 is removed as it is not needed anymore.
3165 * The silc_server_notify now checks on JOIN notify whether the joining
3166 client is one of locally connected or global. If it is global then
3167 the channel has now global users on the channel and that is marked
3168 to the channel entry. Also, it now saves the global client to
3169 global list who is joining and JOINs it to the channel. This is
3170 for normal server, that is.
3172 Changed silc_server_send_notify_on_channel,
3173 silc_server_packet_relay_to_channel and
3174 silc_server_packet_send_to_channel check if we are normal server
3175 and client has router set (ie. global client) do not send the
3176 message to that client, as it is already routed to our router.
3178 * Implemented LEAVE notify type handling in silc_server_notify
3181 * Tested LEAVE command in router environment successfully. Tested
3182 with two routers, two servers and two clients.
3186 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3188 * Implemented SIGNOFF notify type handling in silc_server_notify
3191 * silc_server_remove_id now removes the client entry from all channels
3192 it has joined and thusly sends SIGNOFF notify type.
3194 * Rewrote the NAMES list generation in server by removing two excess
3195 loops. The lists are created now inside one loop.
3197 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * silc_server_remove_channel_user checks now also global list
3200 for channel and client.
3202 * silc_server_new_channel_user checks now both local and global
3203 list for channel and client. Fixed a bug in client id decoding.
3204 Used to decode wrong buffer.
3206 * silc_server_channel_message checks now both local and global
3207 list for channel entry.
3209 * Tested channel joining (hence JOIN) in router environment
3210 successfully. Tested with two routers, two servers and two
3213 * Tested channel message sending in router environment successfully.
3215 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Added silc_server_save_channel_key into server.[ch] to save the
3218 received channel key in Channel Key payload processing. It is
3219 also used in JOIN command reply handling.
3221 Equivalent function silc_client_save_channel_key added into
3222 client.[ch] into client library.
3224 * Changed JOIN command reply to send information whether the channel
3225 was created or not (is existing already) and the channel key
3226 payload. Changed protocol specs accordingly.
3228 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3229 the request was sent by ID and not by nickname. Crashed on
3232 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3235 now correctly save the received data.
3237 * silc_server_free_sock_user_data now notifies routers in the
3238 network about entities leaving the network.
3240 At the same time implemented functions silc_server_remove_id
3241 and silc_server_send_remove_id to receive and send REMOVE_ID
3242 packets. The packet is used to notify routers in the network
3243 about leaving entities. The ID removed will become invalid in
3246 * Added function silc_idlist_del_server into server. Removes and
3247 free's server entry from ID list.
3249 * silc_server_private_message function now checks, if we are router,
3250 that the destination ID really is valid ID, naturally.
3252 * In router when NEW_ID packet is received (for new client) the
3253 hash of the Client ID is saved in the ID Cache but the
3254 client->nickname is set to NULL, instead of putting the hash
3257 IDENTIFY command now also checks that client->nickname must be
3258 valid. If it is not if will request the data from the server who
3259 owns the client. Added new function
3260 silc_server_command_identify_check.
3262 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3263 to set the command to already allocated Command Payload.
3265 * Tested private message sending in router environment with two
3266 routers, two servers and two clients. Fixed minor bugs and now
3269 * Fixed segfault from client's NAMES command. Used to crash if
3272 * Forwarded packets must not be routed even if it is not destined
3273 to the receiver. Changed server code comply with this.
3275 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Added `require_reverse_mapping' boolean value to ServerParams
3278 structure. If TRUE (not default) the server will require that
3279 the connecting host has fully qualified domain name.
3281 If the reverse mapping is not required and hostname could not be
3282 found the IP address is used as hostname.
3284 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Implemented version string checking to both client and server.
3287 The check is incomplete currently due to the abnormal version
3288 strings used in development version of SILC.
3290 * Changed all command functions in server to use the new
3293 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Changed char *data to unsigned char *data in ID Cache system to
3296 support binary data as ID Cache data. Changed code to support
3297 binary data in lib/silccore/idcache.c.
3299 * Renamed silc_server_packet_relay_command_reply to
3300 silc_server_command_reply as it is normal packet receiving
3301 function. Rewrote the function to accept command replys for
3302 servers and not only for clients.
3304 * Mark remote router always as registered server if we are connecting
3305 to it. Otherwise, commands sent by the router to us are ignored.
3307 * All ID List find routines now returns the ID Cache Entry pointer
3308 as well if requested.
3310 * WHOIS command works now in router environment, tested with two
3311 routers, two servers and two clients.
3313 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3314 in router environment (as it is almost equivalent to WHOIS) but
3315 hasn't been tested thoroughly. Added new functions:
3317 silc_server_command_identify_parse
3318 silc_server_command_identify_send_reply
3319 silc_server_command_identify_from_client
3320 silc_server_command_identify_from_server
3322 * Disabled route cache adding because adding two different ID's with
3323 same IP replaces the old cache entry thus giving wrong route.
3324 The entry->router->connection is always the fastest route anyway
3325 so route cache may not be needed. Of course, new routes maybe
3326 established after receiving the ID when the entry->router->connection
3327 might not be anymore the most optimal.
3329 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Add route cache for received ID for fast routing.
3333 * Added silc_server_packet_route to route received packet on router
3334 that is not destined to us.
3336 * Renamed silc_server_get_route to silc_server_route_get.
3338 * Added id_string and id_string_len fields into SilcServer to
3339 include encoded ServerID for fast comparing without excess
3340 encoding of the ID's.
3342 * Cleaned up WHOIS command on server side. Added following static
3345 silc_server_command_whois_parse
3346 silc_server_command_whois_check
3347 silc_server_command_whois_send_reply
3348 silc_server_command_whois_from_client
3349 silc_server_command_whois_from_server
3351 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3352 arguments in command replies. All command functions should be
3353 updated to use this macro.
3355 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Minor typo fixes on command reply handling on server.
3359 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Added silc_server_command_add_to_channel internal routine to add
3362 the client to the channel after router has created the channel and
3363 sent command reply to the server.
3365 * Added generic silc_server_send_command to send any command from
3368 * Use static buffer with ID rendering instead of duplicating data.
3370 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Fixed a channel user mode bug when joining to a channel server gave
3373 everybody channel founder rights, oops.
3375 * We mark ourselves as the router of the incoming server connection
3376 if we are router ourselves. This way we can check in some packet
3377 sending functions whether it is locally connected server. For
3378 incoming router connections we put NULL.
3380 * For router sending packets locally means now always sending the
3381 packet cell wide; to local clients and local servers. For normal
3382 server sending packet locally means sending it to only local
3385 * Fixed the JOIN command to really work in router environment. If the
3386 channel is created it is always created by the router. Router is
3387 also responsible of making the initial joining to the channel,
3388 sending JOIN notify to the sending server and distributing
3389 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3390 does not exist server doesn't do anything else but forward the
3391 command to the router which performs everything.
3393 * Added silc_server_send_channel_key function to send the Channel Key
3396 * Added silc_server_create_channel_key to create new channel key. The
3397 channel key is now re-generated everytime someone joins or leaves
3398 a channel, as protocol dictates. Note: channel->key_len is the
3401 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3404 packet_receive.[ch] to separate packet sending and receiving
3405 routines. The server.[ch] now includes everything else including
3406 actual packet processing (writing and reading data) and other
3409 Renamed silc_server_private_message_send_internal to
3410 silc_server_send_private_message. The routine is still though
3411 used only to relay private messages as server does not send
3412 private messages itself.
3414 Renamed silc_server_new_channel to silc_server_create_new_channel
3415 and added new function sicl_server_new_channel that handles the
3416 incoming New Channel packet. Added also new sending function
3417 silc_server_send_new_channel to send New Channel Payload.
3419 * Added new function silc_server_notify to process incoming notify
3420 packet to the server/router. Server may then relay the notify
3421 to clients if needed.
3423 * Added new function silc_server_new_channel_user to process incoming
3424 New Channel User packet. Router will redistribute the packet and
3425 send JOIN notify to its local clients and locally connected servers
3426 if needed. Normal server will send JOIN notify to its local client
3427 on same channel when received this packet. Added also corresponding
3428 sending function silc_server_send_new_channel_user to sent the
3431 * Added boolean route argument to send_notif_to_channel and
3432 packet_send_to_channel functions to attempt to route the packet
3433 if it is TRUE and send only locally if it is FALSE.
3435 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * silc_server_replace_id now broadcasts the received replace ID
3438 packet if it is not broadcast packet already. The router must
3439 broadcast to inform other routers about changed ID.
3441 * Added backpointer to server's router into SilcServer context in
3442 silcd/server_internal.h.
3444 * Fixed silc_server_packet_broadcast to send correct broadcast
3447 * The channel key is now distributed to the local client as soon
3448 as it is received from the router (in router environment) so that
3449 no other packet may be sent for the channel until client has
3452 * silc_server_remove_channel_user now broadcasts the received
3453 Remove Channel User packet if it is not broadcast packet already.
3454 The router must broadcast to inform other routers about removed
3457 * Added users field into SilcPacketContext that is a reference count
3458 of the context. One can increase the reference count by calling
3459 silc_packet_context_dup which is now changed to just increase the
3460 reference count instead of duplicating the data. The reference
3461 count is decresed by calling silc_packet_context_free that will
3462 free the data after the reference count hits zero.
3464 For now on the packet context and everything allocated into it
3465 (including the raw packet from network) must be freed by calling
3466 the new silc_packet_context_free function. Added also new function
3467 silc_packet_context_alloc that must be used now to allocate the
3468 context. This also means that if a routine is asynchronous from
3469 silc_[client/server]_packet_parse_type the packet context must
3470 be duplicated by calling silc_packet_context_dup. Otherwise it
3471 gets free'd after silc_[client/server]_packet_parse_type returns.
3472 Also, one must remember that if packet is duplicated then its
3473 reference count must be decresed by calling the free function as
3474 many times as it was duplicated.
3476 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3477 from both client and server.
3479 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Made joining to a channel working in router environment.
3483 * Cleaned up JOIN command on server side and create function
3484 silc_server_command_join_channel internal routine to make the
3487 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Changed silc_command_pending list to SilcDList. Also, added
3490 `ident' field to SilcServerCommandPending structure to identify
3491 the reply and to call correct callback.
3493 Added silc_server_command_pending_check function to replace the
3494 corresnponding macro. The silc_command_pending list is not
3497 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3498 to set identifier to previously allocated Command Payload. It
3499 is used to set identifier for command when resending Command
3502 * Added silc_command_payload_encode_payload to encode Command
3503 Payload buffer from SilcCommandPayload structure.
3505 * Added silc_argument_payload_encode_payload to encode Argument
3506 payload buffer from SilcArgumentPayload structure.
3508 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Changed WHOIS command to support router connection on server side.
3511 The whois request is always sent to router unless the server is
3512 standalone server. After server has received the reply from the
3513 router will it send the reply to the client.
3515 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3516 broadcast received broadcast packet. The function is used only
3517 by router. The broadcast packet is always sent to the router's
3520 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3521 render given ID to printable string, for log files for example.
3523 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Made basic router to router connections working. At least they
3526 can now connect to each other but nothing really works the way
3527 they are supposed - yet.
3529 * Added new initiator token to RouterConnection configuration
3530 file in silcd/serverconfig.[ch]. It is used to tell whether we
3531 are the initiator to the remote router or whether we'll expect
3532 the other end to connect.
3534 * Moved registering of listener task to silc_server_init, hence
3535 the server starts listenning as soon as it is run, even if it
3536 does not have connections to other routers. Let's see how well
3539 * Changed default connection retry timeouts for more suitable in
3542 * Removed cipher and such arguments from silc_idlist_add_client
3543 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3544 Added new function silc_idlist_add_data to add the keys and stuff
3547 * Added SilcIDListData structure and added it to SilcClientEntry
3548 and SilcServerEntry as their first field in the structure. This
3549 way we can explicitly cast the ID entries to the SilcIDListData
3550 structure and get common data for the entries. In past, we had
3551 to first check what type of connection it is and then cast it to
3552 correct ID entry type. Now, we can directly cast the opaque
3553 pointer to the SilcIDListData (no matter what ID entry it actually
3554 is) and get the data needed.
3556 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3559 in some circumstances even if threre were timeout tasks, though not
3560 IO tasks, but tasks anyway. Now fixed.
3562 * Defined SilcServerConnection structure to hold connection specific
3563 stuff about directly connected servers and routers. The definition
3564 is currently in silcd/server_internal.h. I thought about having
3565 a bit more important role fro this struct but for now it is used
3566 only when connecting to other server (or router actually).
3568 * Added connecting retry support in server when connecting to
3569 router(s). The retry feature implement exponential backoff
3570 algorithm. Also, added SilcServerParams structure to hold default
3571 parameters for server. For now, it include these retry settings
3572 and are hard coded. After server is moded to be as Silc Server
3573 Library this structure will be more important.
3575 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Changed client librarys channel->clients table to SilcList and
3578 changed code accordingly.
3580 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Changed client's channel table to SilcList and changed code
3583 accordingly. Also changed SilcChannelClientEntry to include back-
3584 pointer to the channel so that client entry can use that structure
3585 as list as well and we have fast cross-reference to the channel.
3586 This change dramatically decreased the complexity of channel
3587 handling with client entry and vice versa (removed one extra
3588 loop when searching for channel entry from many functions).
3590 * Changed server->sim from table to SilcDList and changed code
3593 * NAMES command can now be used from user interface. It will show
3594 the user list on the channel, neatly.
3596 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3597 Code now saves realname of the user if it becomes available.
3599 * Renamed configure.in to configure.in.pre and made ./prepare
3600 script to automatically add correct version string to
3601 configure.in which it creates from configure.in.pre.
3603 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * NAMES command reply now shows users mode with the nickname when
3608 * Moved silc_client_ch[u]mode[_char] functions from
3609 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3610 place sucks, they are utility functions and should be in some
3613 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3615 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3618 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Added TRQ (efficient deque and list library) into lib/trq. This is
3623 a very good list library that is currently used in the SILC. Defined
3624 SilcList API over the library because I didn't like the API very
3625 much. See lib/trq/silclist.h for the API and examples of how to
3626 use the API. Fixed various places in the code to use the new
3627 SilcList API. The SilcList is meant for lists that has a structure
3628 already defined as a list. It is not suitable to add just some
3629 context to the list (in TRQ, the context is the list actually).
3631 So, I defined SilcDList that can be used for the purpose where
3632 predefined list structure does not exit. This can be used as
3633 such list. Now some context just can be added to the SilcDList.
3634 Currently this list is not used in the SILC just yet, though there
3635 are a lot places where this can replace dynamically allocated
3636 tables and I will fix these places, later, to use SilcDList.
3637 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3638 and use TRQ internally).
3640 Also fixed some annoying warning messages that the original TRQ
3641 code generated. Also minor changes to TRQ's Makefile.in.
3643 * Added support for querying by Client ID to both WHOIS and
3644 IDENTIFY commands into server, as required by the protocol.
3646 * Removed method function pointers from SilcBuffer structure. They
3647 weren't used to anything and just increased the context size for
3648 no good reason. This change also made silc_buffer_alloc and
3649 silc_buffer_free functions inline functions.
3651 * Disabled command flooding detection support until it's fixed so
3652 that it accepts commands in but does not execute them more than once
3655 * Added silc_net_localhost(), to return local hostname, into
3656 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3657 that must be initialized before calling silc_client_init.
3659 * Added new function: silc_server_send_notify_on_channels to send
3660 notify messages to all channels client has joined. It is assured
3661 that the message is sent only once per client.
3663 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3664 lib/silcutil/silcutil.[ch] as silc_format function. The new
3665 function is generic and is used by server as well, not only by
3666 the logging routines.
3668 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3669 the provided version string was not acceptable. Added new function:
3670 silc_ske_check_version into lib/silcske/silcske.h. The function
3671 must be implemented by the application (client or server) and it
3672 does not reside in the SKE library. The function checks the version
3673 string remote end sent.
3675 * Added back pointers (to opaque context and to SilcSocketConnection)
3676 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3678 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3679 duplicate packet context structure.
3681 * Changed `notify' client operation to send same arguments as client
3682 receives from server except for ID's. ID's are mapped to correct
3683 ID entry and that is returned. Also, if channel entry is not sent
3684 by server but the notify is for channel the channel entry is sent
3685 to application (otherwise application doesn't know that it is for
3686 channel (library gets it from packet's Destination ID)).
3688 * Added silc_client_remove_from_channels into client library to
3689 remove a client from all channels it has joined to. Used when
3690 received SIGNOFF notify from server. Added also new function
3691 silc_client_replace_from_channels to replace old ID entry with
3692 new ID entry on all channels. Used when received NICK_CHANGE
3695 * Fixed ID Cache list handling in silc_idlist_get_client in
3696 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3697 to get (or query) client by ID.
3699 * Updated TODO list.
3701 * Added connection authentication status message defined by the
3702 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3703 support for these into the code in client and server side.
3705 * Added generic function silc_client_send_command to send any command
3706 with variable argument list. Application should use this function
3707 to send commands if the command functions provided by the library
3708 does not suite for the application's user interface needs.
3710 * Added new `failure' client operation. Application is notified about
3711 received failure packet if client is executing a protocol. In this
3712 case the protocol's execution has failed.
3714 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3715 is required by the protocol.
3717 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3718 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3721 * Added status flag to SilcSKE object to indicate realtime status
3722 of the SKE protocol.
3724 * Application receives now exactly same command reply arguments as
3725 the library receives from server. However, if ID is received the
3726 corresponding ID entry is returned to the application (eg. Client
3727 ID is mapped to correct SilcClientEntry entry and that is returned).
3728 Changed command_reply client operation due to this change.
3730 * Changed all ID's in commands and in command replys as ID Payloads.
3731 Change affected both client and server side codes.
3733 All ID's sent in SILC network (with execption of ID's in SILC
3734 Packet header) are sent in ID Payload to support variable length
3737 * Server now notifies nick changes and notifies all clients on
3738 the channels about the new nickname (about the new Client ID,
3741 * Implemented CMODE command to change channel modes. Supports all
3742 channel modes defined by the protocol specs except ban and invite
3743 lists. (Also, private channel key mode is supported but support for
3744 setting private channel key in client is missing, thus, this mode
3745 has no effect on client side (except that server requires that the
3746 client uses private channel key and normal channel traffic does not
3749 Also, invite mode works per se, but INVITE command does not work
3750 yet correctly, so you can set channel as invite only channel but
3751 inviting clients to the channel does not work (it is yet to be
3752 thought what's the best way to do it).
3754 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3755 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3756 Implemented CUMODE command to change user's mode on the channel.
3757 Supports all modes defined by the protocol specs.
3759 * Added NAMES command reply to return users modes on the channel.
3761 * Removed unnecessary and slow ciphers from lib/silccrypt.
3763 * Set SO_KEEPALIVE option to connection sockets by default.
3765 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3767 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3768 redefined the Notify Payload into protocol specs.
3770 * Added silc_id_payload_parse_id to get ID directly from raw
3773 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3776 accept searching by Client ID as well.
3778 * Added support for LEAVE and SIGNOFF notify types in client library.
3780 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3781 to parse ID Payload from raw data.
3783 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added flags parameter into silc_ske_assemble_security_properties
3786 function in lib/silcske/silcske.[ch].
3788 * Changed notify client operation to fit better for notify messages
3789 sent by server. The notify payload received from server is now
3790 passed to the application (after parsing it to SilcNotifyPayload).
3791 It is application's responsibility to retrieve the arguments
3792 from the payload and show the message the way it wants. The message
3793 sent by server is implementation specific.
3795 * Changed public keys to comply with the protocol specification.
3796 Old public keys are not supported anymore and are not compatible.
3798 * Removed nickname from Channel Payload as the latest draft removed
3799 it. The client must resolve the nickname from the NAMES command
3800 reply received when it joined the channel.
3802 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3804 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Fixed some errors in protocol specification drafts.
3808 * Created lib/silccore/silcnotify.c to implement Notify Payload
3809 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3810 generic payloads described by protocol specifications. The file
3811 includes implementations for ID Payload and Argument Payload.
3813 * Changed Command Payload implementation to use the new Argument
3814 Payload. Changed command_xxxx_payload to command_payload_xxxx
3815 to comply with SILC coding conventions.
3817 * Added suppport for Argument Payload handling in Notify Payload
3818 implementation as protocol requires it. Added the new support
3819 into server and client lib as well.
3821 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Added support for multiple nicknames on same channel. [n] is
3824 added locally to the nickname if there are more than one same
3825 nicknames on the channel.
3827 * Server now sends all nicknames that matched WHOIS request.
3828 Client also shows the list received from server.
3830 * Added TOPIC command to client side. User can now set and show
3831 current topic on channel.
3833 * Added MOTD command to client and server. Also, server sends the
3834 motd when client connects to the server.
3836 * Changed version strings to comply ISO 8601.
3838 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Fixed protocol error handling in client library. It should now
3841 cope even if the SKE fails for some reason.
3843 * Made new protocol specification drafts for submitting to IETF.
3845 * Implemented TOPIC command to server in silcd/command.c.
3847 * Added two new notify types into lib/silccore/silcnotify.h:
3848 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3849 notify nickname change and topic setting/change on a channel.
3851 * API change of command_reply operation in client library. The
3852 application gets now the status type received from server as well.
3854 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3858 * Cras fixed and optimized the packet handling even further and
3859 it should work now. Minor change to the prototype of function
3860 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3862 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added new function into lib/silcutil/silcschedule.[ch]:
3865 silc_schedule_with_fd to select() a specified fd. The function
3866 returns after timeout expires or data arrives or goes. The
3867 function is used by packet routines to wait that all data is
3868 received from network.
3870 * Fixed data reading from network in lib/silccore/silcpacket.c.
3871 The code now assures that all data is read from the fd and then
3872 continues packet processing. This was a bug fix since the code
3873 used to drop some data in some circumstances.
3875 * Added new function into lib/silcclient/client.[ch]:
3876 silc_client_start_key_exchange to start key exchange after
3877 connection has been established to server. The code internally
3878 now uses this funtion but its main purpose was to provide it
3879 for applications that perform their own connecting. After
3880 application has created a connection it merely calls this
3881 function to start the key exchange between client and server.
3882 The library takes care of everything else after that.
3884 Updated also lib/silcclient/README to explain the usage of
3887 * Do not send to application information that connection has
3888 been established. Application gets notified it by connect
3891 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Applied cras's patch to add silc_schedule_one function. The
3894 function runs scheduler once and returns.
3896 * Fixed the scheduler after cras messed it up. The timeout
3897 handling works now as it's supposed to work.
3899 * Added into lib/silccore/ silcnotify.h to include notify
3900 message types support. Changed silc_server_send_notify*
3901 functions, in server.[ch], to support those new notify types.
3902 Added the support for the notify types into client library,
3903 as well. Added new notify client operation into ops.h in
3906 * Changed silc_server_packet_send_to_channel to send normal
3907 packets instead of just channel message packets. The function
3908 is now used to send the notify packets to channels. It is not
3909 used to send channel message packets anymore, as server never
3912 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3913 va_arg()s as it seems to require it nowadays. I guess, if SILC
3914 is compiled with older va_arg() the new code should work anyway.
3916 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Splitted core library. Core library (lib/silccore) includes
3919 now only SILC protocol specific core (and common) components.
3920 Created new utility library (lib/silcutil) that includes more
3921 generic purpose stuff. The stuff for util library was taken
3922 from the old core library. This was minor and easy split.
3924 * Created SILC Client Library (lib/silcclient) that includes
3925 implementation of the SILC client without user interface. This
3926 was major move from silc/ directory. The code has been changed
3927 so that it is transparent towards the user interface. The
3928 silc/ directory includes now the same user interface as before
3929 and it uses the new client library. Read lib/silcclient/README.
3930 Basicly, the client library performs everything else related
3931 to SILC except user interface handling. Also, configuration
3932 files are considered to be part of user interface and library
3933 does not handle them.
3935 This change also changed a lot of structures, function naming etc.
3936 Most important change was that SilcClientWindow object was
3937 renamed to SilcClientConnection in the client library. Created
3938 also new file lib/silcclient/ops.h. Also added new files
3939 silc/local_command.[ch] and silc/client_ops.[ch].
3941 All these changes were made to make it easier for user interface
3942 designers to create what ever user interface for the SILC client
3945 It is also expected that the server will be moved to lib
3946 directory as well and SILC Server Library will be created;
3947 sometimes in the future.
3949 * Removed Local commands from lib/silccore/silccommand.h as
3950 they are application specific and new client library does not
3951 handle any of those anymore.
3953 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3954 old client implementation in silc/.
3956 * Added support for callback functions in SILC_LOG_* macros.
3957 Application can now set its own callbacks that will be called
3958 instead of using the default functions that will always print
3959 the debug messages to stderr (or stdout). Also, debugging can
3960 now be disabled by setting silc_debug to FALSE and re-enabled by
3961 setting it to TRUE. Note, that logging will still work even
3962 if debugging is disabled.
3964 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3965 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3966 silc_log_reset_debug_callbacks.
3968 * To enable debugging in silc client one must give now -d
3969 option on command line.
3971 * Changed silc_schedule_init to automatically allocate task queues
3972 if they are not allocated before calling it.
3974 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added GMP 3.1 into math library.
3978 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3981 a channel in SILC network. The packet is used by servers and
3982 routers to notify other routers that user has left a channel.
3983 This little feature was missing until now. Added the feature
3984 to protocol specification as well.
3986 Added functions: silc_server_send_remove_channel_user and
3987 silc_server_remove_channel_user into server.[ch].
3989 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3990 lib/silccore/silcpacket.h. However, they are not implemented
3993 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Fixed joining to a channel and sending channel messages
3996 between server and router. The channel message sending should
3997 now work inside a cell.
3999 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed the private message sending between server and router.
4002 The private message sending should now work inside a cell.
4004 * Added silc_server_replace_id into server.[ch] to replace
4005 existing ID in the SILC network.
4007 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4008 and silc_idlist_replace_server_id into idlist.[ch] in server.
4010 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Fixed the server to server connections. Server can again now
4013 connect to router. Router to router connections probably does
4016 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Added dynamic protocol registering support. Now protocols can
4019 registered and unregistered on the fly. Patch by cras.
4021 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Added lib/contrib directory to hold routines that some platforms
4024 don't have but are needed by SILC.
4026 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4027 into lin/contrib to provide getopt() and getopt_long() for
4028 those who don't have it.
4030 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Added AWAY command to client. When away message is set and
4033 client receives a private message packet the client automatically
4034 replies to the sender with the away message.
4036 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4037 bug seemed to be the cause of recent problems when compiling
4040 * Added version detection support to SKE protocol specification
4041 and added the new changes to the SKE implementation as well.
4042 There were other minor changes in the SKE protocol as well.
4044 Many changes in lib/silcske/silcske.[ch] and in
4045 lib/silcske/payload.[ch].
4047 * Added ^U functionality, clear input line. Patch from cras.
4049 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Mainly small bugfixes on core library. Fixed some debugging
4052 logging and buffer overflow in silclog.c.
4054 * Updated config.sub and config.guess on the distribution tree.
4056 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Added command lagging support in server. Client may execute
4059 commands now only once in two seconds.
4061 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Optimized packet reception. MAC computation and checking is now
4064 also more optimized. A lot previously duplicated code is now
4065 used as generic by both client and server.
4067 * Fixed key pair generation in clientutil.c
4069 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Added into lib/silccore/silcbufutil.[ch] new function;
4072 silc_buffer_realloc.
4074 * Moved generic packet sending/encryption functions to
4075 lib/silccore/silcpacket.[ch] from client and server. Some
4076 rewriting of the functions.
4078 * Moved all generic packet reception/decryption functions to
4079 lib/silccore/silcpacket.[ch] from client and server. The
4080 packet processing is now much cleaner in both client and server.
4081 These were major changes in both client and server.
4083 * Created many common functions in server to do packet sending.
4084 Previously code were duplicated a lot, this has been removed
4087 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Rewrote major parts of the ID cache system. Don't know
4090 whether it is better now or not but at least the API is more
4093 * Major rewrite on ID cache stuff on client because of the ID
4094 cache API changes. Added idlist.c to client.
4096 * Also major rewrite on ID cache stuff on server as well.
4097 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4098 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4099 in hand, instead they are all put into the ID cache system now.
4100 All server_idlist_* routines uses ID cache now instead of
4101 traversing its own lists (those lists does not exist anymore).
4102 SilcIDList though still exists. Also, SilcXXXEntry's are
4105 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Finally made the SKE implementation compliant to the protocol
4108 specification. All mp integers are now binary encoded as
4109 opposed being HEX encoded.
4111 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4114 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4115 functions: silc_[encode/decode]_pem. Also added function
4116 silc_encode_pem_file to PEM encode with newlines ('\n') for
4119 * SILC public keys are now encoded either PEM or binary. Same
4120 option is for private keys as well. By default private keys
4121 are binary encoded and public keys PEM encoded. Silly HEX
4122 encoding were removed.
4124 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4125 function to create fingerprints.
4127 * Fixed a bug in SHA1; does not change the original data anymore.
4129 * Partly implemented INFO command on client and server side.
4130 Fixed CLEAR command. Changes to SERVER command; show current
4131 server(s) when giving command without arguments. Added
4132 VERSION command to client.
4134 * Added check to server that unregistered connections cannot
4135 execute commands (unless it is specificly allowed).
4137 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Fixed screen refresh.
4141 * Fixed channel joining bug from client. On some circumstances
4142 client tried to join to a channel it had already joined.
4144 * Added public key verification process into client's protocol.c.
4145 The client now verifies the public key from user and saves
4146 it into ~./silc/serverkeys/ directory.
4148 Added into: clientutil.[ch]: silc_client_verify_server_key.
4150 * Changed SKE protocol's silc_ske_initiator_finish function
4151 to accept callback function that verifies the received public
4152 key. Removed old silc_ske_verify_public_key function.
4154 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4157 silc_pkcs_private_key[_data]_set.
4159 * Made the password and public authentication more cleaner in
4160 server's protocol.c.
4162 * Removed historic and obsolete protocol `channel_auth' from
4163 both client and server.
4165 * Removed wrong way of sending command status messages from
4166 server to client in server's command.c. The old way violated
4167 protocol specification.
4169 Changes to silccore/silccommand.[ch]: removed
4170 silc_command_encode_status_payload -> not needed anymore,
4171 changed silc_command_encode_payload_va to accept extra
4172 argument on variable argument list. The argument type must
4173 now be provided to the function. Also, added new function:
4174 silc_command_encode_reply_payload_va which is same as
4175 normal command_encode_payload_va except command status type
4176 is provided as extra argument.
4178 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added ~./silc directory handling. The directory includes the
4181 public and private keys for the client.
4183 Added silc_client_check_silc_dir, silc_client_create_identifier
4184 and silc_client_load_keys.
4186 * Implemented SILC protocol compliant public key. Added public
4187 and private key saving to and loading from files.
4189 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4190 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4191 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4192 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4193 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4195 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4196 silc_pkcs_load_[public/private]_key.
4198 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Added silc_server_get_route (route.[ch]) to get connection
4201 data for the fastest route for given ID.
4203 * Implemented INVITE command on client and server. The command
4204 were re-defined in the SILC Protocol Specification and the
4205 implementation now complies with the specification.
4207 * Implemented PING command on client and server.
4209 * Implemented NAMES command on client and server. The server side
4210 supports currently only normal server not router server yet.
4211 Some changes to NAMES definition in SILC protocol specification.
4213 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Implemented LEAVE command on client and server.
4217 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4218 again. This change was made to the protocol as well. Server
4219 should not violate the protocol specification anymore.
4221 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4224 was tested. SOCKS4 was not but should work anyway.
