1 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4 library as they clearly belong there. As a plus side we
5 can make the actual socket connection routines platform
8 Added also new generic function silc_socket_read and
9 silc_socket_write (that used to be silc_packet_[read/write].
10 The implementation of these are platform specific.
12 * Added WIN32 specific routines of silc_socket_[read/write]
13 to lib/silcutil/win32/silcwin32sockconn.c.
15 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
17 * Added preliminary support for native WIN32 compilation under
18 cygwin (using the -mno-cygwin option for GCC) to the
19 ./configure.in.pre. The --with-win32 now prepares the
20 compilation for native WIN32.
22 * Rewrote the SILC Scheduler interface in the file
23 lib/silcutil/silcschedule.h. The scheduler is now context
24 based and does not have anymore any global static scheduler.
25 Moved the Unix scheduler to the lib/silcutil/unix/ directory
26 and created lib/silcutil/win32 directory for WIN32 based
29 * Added Unix specific network routines to the
30 lib/silcutil/unix/silcunixnet.c and the old
31 lib/silcutil/silcnet.c includes now only generic routines.
33 Added WIN32 specific network routines to the
34 lib/silcutil/win32/silcwin32net.c.
36 * Added Unix specific utility functions from the
37 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
39 * Added WIN32 SILC Scheduler to the file
40 lib/silcutil/win32/silcwin32schedule.c. The code is of course
43 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Do not handle JOIN notify in the server if the target client
46 is not registered (idata->registered == FALSE). The affected
47 file is silcd/packet_receive.c.
49 * Update the nickrec->founder in event_cumode in the Irssi SILC
50 client. Affected file irssi/src/silc/core/silc-channels.c.
52 * Fixed the CUMODE_CHANGE notify handling in the server when
53 server and router are announcing their clients on channels.
54 Now the mode changes are saved and notified correctly. The
55 affected file is /silcd/packet_receive.c.
57 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
58 They really did not replace the cache entry in the ID Cache.
59 Now they do that. Affected file silcd/idlist.c.
61 * Fixed the KICK notify handling in the Irssi SILC client to
62 update the channel records so that the kicked client does not
63 appear to be on the channel. The affected file is
64 irssi/src/silc/core/silc-channels.c.
66 * Always update the conn->current_channel when executing command
67 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
69 * Fixed the KILL notify handling in Irssi SILC client to remove
70 the killed client on all channels.
72 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * Fixed the silc_parse_command_line to remove extra spaces
75 from the start and end of the arguments. Affected file is
76 lib/silcutil/silcutil.c.
78 * Cancel and free any active protocol in the function
79 silc_server_close_connection. Affected file silcd/server.c.
81 * Cancel and free any active protocol in the function
82 silc_client_close_connction. Affected file is
83 lib/silcclient/client.c.
85 * Do not execute the KILL command for clients that are in
86 history (ie. they are not in the network). Affected file is
89 * Fixed KILL notify handling, client does not crash anymore.
90 Affected file irssi/src/silc/core/silc-channels.c.
92 * Reduced the default packet buffer size from 2048 to 1024 in
93 lib/silccore/silcpacket.c.
95 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
96 counter to the SKE context that is incresed when the SKE library
97 performs async operation outside the library. If the outside
98 process frees the SKE context and FREED status will be set
99 and the library will detect after the sync operation that the
100 libary is freed. The affected files are
101 lib/silcske/silcske[_status].[ch].
103 * Resolve the client entry information in the function
104 silc_client_channel_message to assure that NULL pointer is not
105 passed as client entry to the application. */
107 * Fixed the task timeout calculation to assure that there is
108 never negative timeouts. The affected file is
109 lib/silcutil/silcschedule.c.
111 * Fixed the channel user mode notification sending in server.
112 It was sent point-to-point to the router (or to server by router)
113 but it needs to be destined to a channel. The routines now
114 supports sending the channel user mode notifys to the channels
115 when announcing clients and channels. Affected files are
116 silcd/server.c and silcd/packet_receive.c.
118 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
119 It did not actually replace the old channel entry in the cache.
120 Affected file lib/silcclient/client_notify.c.
122 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Fixed a possible crash in silc_packet_send_prepare. It now
125 assures always that there is enough space in the buffer and
126 at the tail area of the buffer (for MAC).
128 Fixed the inbound buffer reallocation in silc_packet_read.
129 It was old code and did not handle the reallocation correctly.
132 The affected file is lib/silccore/silcpacket.c.
134 * Fixed buffer overflow in silc_parse_nickname in the file
135 lib/silcutil/silcutil.c.
137 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * make install generates new server keys only if there is not
142 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
145 Added check that if the NOREPLY is set then we will not send
146 the away message. This avoids infinite loop of away messages
147 if both clients are away. The affected file is
148 lib/silcclient/client_prvmsg.c.
150 * Fixed client crash if /NICK was given without arguments.
151 Affected file lib/silcclient/command.c.
153 * Server does not send the invite list in INVITE command back
154 to the client if the list was not altered. Added this notion
155 to the protocol spec as well. Affected file silcd/command.c.
157 Fixed possible crash in INVITE command by checking the
158 value of silc_server_get_client_route command.
160 * Fixed the INVITE notify type handling. The arguments are now
161 taken in correct order and client does not crash. The affected
162 file is irssi/src/silc/core/silc-channels.c.
164 Removed the "Inviting xxx to channel" message from the
165 client library away and let the application handle it.
166 Affected file lib/silcclient/command.c. Added that message
167 to Irssi SILC client's message formats.
169 * Fixed CMODE command crash in client. It now checks the
170 amount of arguments correctly and does not crash. The affected
171 file is lib/silcclient/command.c.
173 * Do not create new channel automatically in silc_channels_join
174 but check whether the channel by that name already exists.
175 Affected file irssi/silc/core/silc-channels.c.
177 * Do not send the SERVER_SIGNOFF to router if the disconnected
178 entity was the router. Affected file silcd/server.c.
180 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
181 SILC client as it was missing from there.
183 Added the handling of the KICK notify to the Irssi SILC client
184 as it was missing. Added "you have been kicked" message to
185 Irssi SILC client's message modules formats.
187 Added the handing of the KILL notify to the Irssi SILC client
188 as it was missing. Added the kill message module formats
191 The affected file is irssi/src/silc/core/silc-channels.c.
193 * The router did not save the channel mode the server announced.
194 Affected file silcd/packet_receive.c.
196 * Fixed a possible crash in INFO command in server. If the
197 server did not provide the server info it crashed. Affected
198 file silcd/command.c.
200 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Fixed the GETKEY command in the server to check also the
203 global list. Otherwise the GETKEY would not work correctly
204 in normal SILC server. Affected file silcd/command.c.
206 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Fixed GETKEY crash, it crashed if the command did not succseed.
210 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
212 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
213 is now real and not just an macro interface to GMP.
215 Removed the entire GMP from the source tree and imported new
216 NSS MPI library instead. Reason for removing GMP is that it is
217 extremely large and compiles extremely slow. The NSS MPI
218 is only a few files and compiles in less than 10 seconds.
219 The speed is also about the same as GMP. The MPI is imported
222 If the system has GMP installed we will still use the GMP.
223 If it is not then the NSS MPI will be compiled.
225 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Merged a long nickname (127 characters long) crash bugfix from
228 Irssi CVS tree. Affected file irssi/src/core/misc.c.
230 * Merged a freed memory reference bugfix from Irssi CVS tree.
231 Affected file irssi/src/core/commands.c.
233 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
235 * Added the server's public key sving and verification to the
236 server when performing the SKE. This was missing and the
237 remote server's (or router's) public key was accepted without
238 checking whether we have it previously or trust it at all.
239 Affected file silcd/protocol.c.
241 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Check in the silc_server_timeout_remote if protocol is active
244 and make sure that the protocol's final callback is called so
245 that all memory if freed. Affected file silcd/server.c.
247 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * silc_server_whois_send_reply crashed the server if the nickname
250 was 127 characters long. Affected file silcd/command.c.
252 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Added sanity check to the silc_server_new_client. If the hostname
255 is provided inside username then check that the provided hostname
256 really is the same as the resolved one. If the hostname was not
257 resolved then check it from the public key. Affected file is
258 silcd/packet_receive.c.
260 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
261 if the server disconnected us and the connection is not valid
262 anymore. Affected file irssi/src/silc/core/silc-channels.c.
264 * Moved the silc_client_[chmode|chumode|chumode_char] away from
265 the library to the lib/silcutil/silcutil.[ch].
267 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
269 * Close log file after open. Affected file
270 lib/silcutil/silclog.c.
272 * Check whether sock == NULL in silc_client_send_packet and return
273 if it is. Affected file lib/silcclient/silcclient.c.
275 * Check rec->entry == NULL in the Irssi SILC Client before
276 sending the channel message. Affecte file is
277 irssi/src/silc/core/silc-servers.c.
279 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
281 * Merged a splitted window bugfix from Irssi CVS tree. The
282 affected file is irssi/src/fe-text/textbuffer-view.c.
284 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
285 It did not print nickname.
287 * Improved the distributions system a bit.
289 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
292 irssi/src/fe-text/gui-window.c.
294 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
295 to in-active server. The affected file is
296 irssi/src/silc/core/client_ops.c.
298 * Resolve the client in USERS command reply if the entry does
299 not have username resolved. The affected file is
300 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
301 command to WHOIS command to really resolve stuff. The USERS
302 is not used any more in any critical section so WHOIS can
303 be used even though it might be slower than IDENTIFY.
305 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
308 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
310 * Changed the protocol API a bit more consistent in the
311 lib/silccore/silcprotocol.[ch].
313 * Changed the following headers to ROBODoc format:
315 lib/silccore/silcpayload.h
316 lib/silccore/silcprotocol.h
317 lib/silccore/silcsockconn.h
319 All core library headers are now formatted.
321 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Fixed a bug in Irssi SILC client; do not show that you are
324 server/router operator if you really are not. Affected file is
325 irssi/src/silc/core/client_ops.c.
327 * Renamed silc_command_free_payload to silc_command_payload_free.
328 Affected file lib/silccore/silccommand.h
330 * Added silcmath.h to include the prototoypes of various routines
331 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
334 * Changed the following headers to ROBODoc format:
336 lib/silccore/silcchannel.h
337 lib/silccore/silccommand.h
338 lib/silccore/silcid.h
339 lib/silccore/silcidcache.h
340 lib/silccore/silcmode.h
341 lib/silccore/silcnotify.h
342 lib/silccore/silcpacket.h
343 lib/silcmath/silcmath.h
345 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
347 * Added checking to the server code not to start the server if
348 ciphers and stuff are not configured properly. Affected files
349 silcd/serverconfig.[h] and silcd/server.c.
351 * Changed the layout of the header files of the public interfaces
352 in the SILC libraries. The new layout supports ROBODoc
353 documentation tool (and some others) so that it is easy to create
354 a library reference manual. All the other headers and source
355 code must still follow the CodingStyle document. Also source
356 code must not include these ROBODoc stuffs, only the headers.
357 Furthermore, all public interface headers must now be named
358 by using `silc' prefix, example: silcapi.h, silccipher.h.
359 Some files were renamed due to this. All the other headers
360 must not be used as public interfaces. I will update the
361 CodingStyle document later. Changed following headers, so far:
363 lib/silcclient/silcapi.h
364 lib/silccore/silcauth.h
365 lib/silccore/silcprivate.h
366 lib/silccrypt/silcdh.h
368 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Removed silc_client_packet_send_flush from the client library
373 as it is not needed. Affected file lib/silcclient/client.[ch].
375 * Added printing of message of unresolved authentication method
376 to the Irssi SILC client. Added it to the module formats.
377 Removed the same message from the client library.
379 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Added new distribution feature, DISTLABEL. Every distribution
382 can define own preprocessor label that can be used in the
383 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
384 file distributions, acconfig.h.pre and prepare.
386 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Added Makefile.defines_int to include the actual definitions
389 for Makefile.defines.in. Tested the new distribution system,
390 created distributions and tested installation.
392 * Added AWAY message printing to the Irssi SILC client. Added
393 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
395 * Added SCONNECT command to call the SILC's CONNECT command.
396 Cannot use CONNECT directly since Irssi uses that internally.
397 Affected file irssi/src/silc/core/silc-servers.c.
399 Added ACTION local command. It is same as ME command but takes
400 the channel as mandatory argument.
402 Rewrote some of the Irssi's help files to suite for SILC
405 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
407 * Added Makefile.defines[.in] that should for now on be included
408 in all Makefile.am file in the source tree. That file includes
409 all common compilation definitions for SILC source tree.
411 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
413 * Minor changes to the ./prepare script to change the package
414 name according the distribution name to the configure.in.
416 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
418 * Created new distribution system. Added file `distributions'
419 that defines all the distributions that can be created out of
420 the SILC source tree. The ./prepare script now reads that
421 file to determine how to prepare the distributions. The
422 first argument to the ./prepare is the name of the distribution
423 and second is the version of the distribution. If given
424 without arguments it creates the default (toolkit) distribution
425 with the default version (defined in ./prepare).
427 All Makefile.am files that are subject to the distributions
428 are now named as Makefile.am.pre. These are ./Makefile.am
429 and lib/Makefile.am. Others may be changed later.
431 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Added invite list, ban list, some key management and connection
434 error message printing to module formats in the Irssi SILC client.
436 * Added new silc_client_set_away_message to set the away message
437 that is back to the person who sent private message. The
438 affected file lib/silcclient/silcapi.h and the
439 lib/silcclient/client_prvmsg.c.
441 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Fixed the private message sending in the Irssi SILC client,
444 added local command KEY to the Irssi SILC client.
446 Added key management and key agreement message formats to the
447 irssi/src/fe-common/silc/module-formats.[ch].
449 Added USERS (alias WHO) printing, server/router operator
450 indication and LIST command printing to the module formats.
452 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Fixed channel joining notify handling, cumode notify handling
455 from Irssi SILC client.
457 * Added SILC specific module-formats to the Irssi SILC client so
458 that SILC specific message hilighting, colors etc is possible.
459 Affected file irssi/src/fe-common/silc/module-formats.[ch].
461 Added channel mode, channel user mode, actions, notices,
462 whois and whowas printing to the the module-formats.c.
464 * Fixed a bug in channel deletion in the server. The channel
465 is not left to the cache even if the channel founder auth mode
466 is set when there are no users anymore on the channel. Affected
469 * The silc_net_localhost now resolves the entire hostname including
470 the domain name. Affected file lib/silcutil/silcnet.c.
472 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * Changed the ask_passphrase client operation to be ascynchronous.
475 It has now a completion callback and a context that the
476 application must call after it has got the passphrase from
477 the user. Affected files lib/silcclient/silcapi.h,
478 lib/silcclient/protocol.c, lib/silcclient/command.c and
481 Added SilcAskPassphrase callback that the application calls
482 to deliver the passphrase to the library.
484 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
485 The public key verification and especially a certificate
486 verification is asynchronous procedure.
488 Added new SILC_SKE_STATUS_PENDING status to indicate the
489 request is pending and a callback will be called to finalize
492 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
493 indicate that remote end did not send its public key (or
494 certificate), even though we require it. Added check for this
495 condition in the SKE. This was a security bug, now fixed.
497 Defined new SilcSKEVerifyCbCompletion callback that is called
498 when the verification process is completed.
500 The affected files lib/silcske/silcske_status.h and
501 lib/silcske/silcske.[ch].
503 * Changed the verify_public_key client operation to be async
504 as well. Defined SilcVerifyPublicKey callback that is used to
505 indicate the success of the public key verification process.
507 Changed the server and client to use the new async client
510 * Changed the Irssi SILC client's internal scheduler to be called
511 twice as many times as it used to be. As a result the client
512 should be a bit faster now. Affected file is
513 irssi/src/silc/core/silc-core.c.
515 * Added support to Irssi SILC client of asynchronous public key
516 verification and passphrase inquiry. Affected file is
517 irssi/src/silc/core/silc-core.c.
519 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Do not say "You have left channel %s" in client library.
522 Moved it to the application. Affected files are
523 lib/silcclient/command.c and silc/client_ops.c.
525 * Fixed silc_client_get_clients. Command context was not
526 duplicated and was freed memory in the callback. Affected
527 file lib/silcclient/idlist.c.
529 * Do not say "you are now talking..." on JOIN command in the
530 client library. The appliation must handle it.
532 * Do not say ".. changed topic to" in command reply in the
533 client libary. The application must handle it.
535 * Fixed TOPIC command sending in the client library.
537 * Fixed a memory leak in silc_client_command_free in the file
538 lib/silcclient/command.c.
540 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Imported a modified version of Irssi client to the source tree.
543 The Irssi will be used to create a new client called
544 Irssi SILC. Imported to irssi/.
546 Added silc_core_init_finish function to the Irssi. Affected
547 file irssi/configure.in.
549 A lot changes in the Makefile.ams around the irssi tree.
551 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Do not rehash if the new size is same as the old size of the
554 hash table, in the silc_hash_table_rehash*. The affected file
555 lib/silcutil/silchashtable.c.
557 * Replaced hash_table_del_by_context calls from the server
558 (when channel->user_list and client->channels) to the
559 hash_table_del as it is sufficient and faster.
561 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
563 * Added silc_hash_table_list, silc_hash_table_get and the
564 SilcHashTableList structure to provide an alternative way to
565 traverse the hash table. The affected files are
566 lib/silcutil/silchashtable.[ch].
568 * Changed the server's idlist routines to use the hash table
569 routines to optimize the code.
571 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
573 * Replaced the client entry's `channel' list and channel entry's
574 `user_list' list to hash tables for optimized lookup. Changed
575 the code to use the hash table interface around the code.
576 Affected file lib/silcd/idlist.[ch].
578 * Added `auto_rehash' boolean argument to the function
579 silc_hash_table_alloc to indicate whether the hash table should
580 auto-rehash when it thinks is appropriate time. It will
581 increase the hash table size if the there is twice as much
582 entries in the table than the size of the table, and will
583 decrease the size if there are twice as less entries than
584 the size of the table.
586 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
588 * Fixed silc_xxx_get_supported to not crash at some circumstances.
590 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * silc_idcache_purge_by_context deletes the entry now by context
593 as it is supposed to do. Affected file lib/silccore/idcache.c.
595 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
596 client is not anymore valid (WHOWAS givens the info) and not
597 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
599 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Removed the `data' and `data_len' arguments from the ID Cache
602 interfaces and added `name' argument. ID Cache does not handle
603 anymore the binary data only a names associated with given ID.
605 * When hashing a Client ID with silc_hash_id the entire ID is
606 not hashed anymore, instead only the hash of the Client ID is
607 hashed. This way we can access the Client ID from the cache
608 with Client ID but with the hash of the ID (which is a hash of
609 the nickname) as well without any difference in performance.
611 Added also silc_idcache_find_by_id_one_ext to do one on one
612 searching when we have the actual ID. Added also function
613 silc_hash_client_id_compare. The affected files are
614 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
616 * When hashing the name associated with a ID it is always done
617 in lowercase. This way we can access the cache without worrying
618 about case-sensitivity, even though, for example nicknames are
621 * Fixed a bug in server with channel message sending. It put
622 wrong ID type as destination ID. The affected file
625 * silc_idcache_del_by_context now deletes from all hash tables
626 by context. Affected file lib/silccore/idcache.c.
628 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
630 * Changed the client library to use the new ID Cache interface.
631 Changes around the source tree.
633 * Added silc_hash_table_rehash_ext to rehash with specific
634 hash function. Affected file lib/silcutil/silchashtable.[ch].
636 * Added silc_hash_string_compare to compare two strings in the
637 hash table. Affected file lib/silcutil/silcutil.[ch].
639 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Added new function silc_idcache_del_by_context into the
642 lib/silccore/idcache.[ch].
644 * Changed the server's ID list routines to use the new ID Cache
645 interface. Changes around the source tree.
647 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Added silc_hash_table_del[_by_context]_ext functions in to the
650 lib/silcutil/silchashtable.[ch].
652 Removed silc_hash_table_find_all* routines and added new
653 silc_hash_table_find_foreach to replace them.
655 Added silc_hash_table_replace_ext function as extended
656 replacing function. Separated the simple hash table interface
657 from the extended hash table interface in the file
658 lib/silcutil/silchashtable.h.
660 * Fixed minor bugs and changed it to use some of the new
661 hash table functions in lib/silccore/idcache.c
663 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Added new function silc_hash_table_find_all to return all keys
666 in the hash table by the specified key. As the hash table is
667 collision resistant it also makes it possible to have several
668 duplicate keys in the hash table. This function may be used to
669 find all of the keys from the hash.
671 Added user_context arguments to the SilcHashFunction,
672 SilcHashCompare and SilcHashDestructor to deliver user specified
675 Added new fuctions silc_hash_table_find[_all]_ext to do
676 extended lookup with specified hash and compare functions and
677 specified user contexts.
679 Added new function silc_hash_table_add_ext to add the key
680 with specified hash function and user context.
682 Added new function silc_hash_table_foreach to traverse all
683 entrys in the hash table. Added SilcHashForeach callback
686 Added new function silc_hash_table_del_by_context to delete
687 the entry only if the context associated with the key matches.
689 Affected files are lib/silcutil/silchashtable.[ch].
691 * Removed silc_hash_[server/client/channel]_id and added just
692 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
693 silc_hash_id_compare to compare two ID's using as the hash table
694 comparison function. Added also silc_hash_data to hash
695 binary data and silc_hash_data_compare to compare it.
697 * Removed silc_idlist_find_client_by_hash as it is not needed
698 anymore. Affected file silcd/idlist.[ch].
700 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
701 to use internally the SilcHashTable. The new ID Cache is a lot
702 faster than the old one. Some of the ID Cache interface was also
703 rewritten and obsolete and stupid functions were removed.
705 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Added entry_count field to the SilcHashTable to keep the number
708 of the entries in the table. Implemented the function
709 silc_hash_table_rehash. Added new function
710 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
712 Fixed a minor bug in silc_hash_table_free.
714 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
715 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
716 into the lib/silcutil/silcutil.[ch].
718 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Implemented a collision resistant hash table into the
721 lib/silcutil/silchashtable[ch]. See the header and the source
722 for the SilcHashTable API.
724 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Merged dotconf version 1.0.2 into lib/dotconf.
728 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Do not compile anything in lib/silcsim/* if the SIM support
731 is not enabled. The tree should now compile without problems
734 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Compiled the SILC under cygwin. Compiled and tested briefly
737 without problems. More tests needed. The SIMs didn't compile
740 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
742 * Fixed possible crash in silc_get_username in the
743 lib/silcutil/silcutil.c.
745 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
747 * Fixed a va_arg in silc/client_ops.c.
749 * Oops, RC5 routines were named AES and caused some problems
750 when not using SIM's. Affected file lib/silccrypt/rc5.c.
752 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Added new SilcIDIP structure into the lib/silccore/id.h and
755 replaced the old `ip' fields from all SILC ID's to that type.
756 This is a step towards IPv6 support.
758 The silc_id_get_len takes now the ID as an extra argument.
759 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
760 both IPv4 and IPv6 based ID's.
762 The affected files are lib/silccore/id.[ch] and other files
763 around the tree using these routines.
765 * Removed the ID length arguments in server from various
766 silc_server_send_notify_* routines -> they are not needed
769 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Fixed memory leak in silc_encode_pem_file in the file
772 lib/silcutil/silcutil.c.
774 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Check minor version as well in the SKE. Affected files are
777 silcd/protocol.c and lib/silcclient/protocol.c.
779 * Added --identifier option to the server so that an identifier
780 can be when creating the public key for the server. Affected
781 file is silcd/silcd.c.
783 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
784 lib/silccrypt/silcpkcs.c.
786 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Register default ciphers and stuff when using -C option with
789 the server. Affected file sildc/silcd.c.
791 * Put back the servers public key filename format, it is better
792 than the new one. For now, the client keys are saved with the
793 new filename format. The affected file silc/client_ops.c.
795 * Implemented the Cipher API for the rest of the ciphers that
796 did not implement it or implemented it the wrong way.
798 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Register default ciphers and stuff when using the -S option
801 in the client. Affected file silc/silc.c. Same also when
802 creating new key pair with -C option.
804 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
806 * Fixed the silc_verify_public_key client operation function to
807 save the public keys differently. The fingerprint is now
808 used as filename and not the hostname. This way also the
809 client keys are saved uniquely and not with hostnames. The
810 affected file is silc/client_ops.c.
812 * Trimmed the silc_hash_fingerprint function to remove extra
813 whitespaces from the end of the fingerprint. The affected
814 file is lib/silccrypt/silchash.c.
818 * Added silc_cipher_register_default function to register all
819 default ciphers. It can be used when configuration files
820 does not exist and the application does not want any specific
821 ciphers in any specific order.
823 The SilcDList is now used as silc_cipher_list dynamically
824 allocated cipher list. Removed the static list all together
825 and now all ciphers must be allocated to the dynamic list.
826 The silc_cipher_alloc routine was changed to check only the
829 All silc_cipher_* routines that used to return int returns
832 The affected files lib/silccrypt/silccrypt.[ch].
834 * The same thing was done to silc_hash_* as for silc_cipher_*
835 routines. Affected files lib/silccrypt/silchash.[ch].
837 * The same thing was done to silc_pkcs_* as for silc_cipher_*
838 routines. Affected files lib/silccrypt/silcpkcs.[ch].
839 Added also silc_pkcs_[un]register[_default] functions.
840 Removed the data_context from the PKCS API.
842 * Added silc_hmac_register_default function to register default
843 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
844 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
845 to unregister all hmacs at once.
847 * Register the default ciphers, hash functions, PKCSs and HMACs
848 if client's configuration file does not exist. The affected
851 * The client did not load the hash functions from the SIM
852 modules at all. Added support for this. Affected file is
855 * When decoding public key with silc_pkcs_public_key_decode, check
856 the supported algorithm only if PKCS are registered. Affected
857 file lib/silccrypt/silcpkcs.c. The same was done with the
858 silc_pkcs_private_key_decode.
860 * Fixed the SILC List routines to keep the list always in order.
861 It used to change the list's order when traversing the list but
862 not it preserves the order. Affected file lib/trq/silclist.h.
864 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Added the client library to use the SilcSocketConnection's
867 reference counter (by silc_socket_dup) to prevent the bug that
868 the socket object may be freed underneath async operation.
870 * The name resolv library checking fixes in the configure.in.pre.
873 * Created new version of the protocol drafts for future
874 development. The -03 drafts are the ones that will be changed
875 in the trunk now and the -02 will remain as they are.
877 * Send list of CUMODE notifys to the router when announcing
878 the channel users to the router. Affected file silcd/server.c.
879 If the router receiving channel founder CUMODE for a channel
880 that already has channel founder it will send CUMODE notify
881 to the sender to remove the channel founder rights from the
882 announced client. Affected file silcd/packet_receive.c.
884 * The CUMODE notify may now use Server ID as well as the entity
885 who changes the mode. Updated protocool specs.
887 * Updated INSTALL and README files.
889 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * New web pages in the http://silc.pspt.fi. The pages was
896 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Implemented the [DenyConnectin] config section in the server.
899 Added silc_server_config_denied_conn to check whether incoming
900 connection is denied. Affected file silcd/serverconfig.[ch].
902 * Do not check the ports when checking the incoming configuration
903 data if the port is 0, meaning any. Affected file is
904 silcd/serverconfig.c.
906 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Fixed buffer overflow in silc_string_compare in the file
909 lib/silcutil/silcutil.c.
911 * Fixed double free in silc_server_command_leave in the file
914 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Fixed the version checking in the server. Affected file is
919 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Fixed the configuration data fetching when accepting new
922 connections in the server. Affected file silcd/server.c.
924 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added `sender_entry' argument to the function
927 silc_server_packet_relay_to_channel so that we can check
928 whether some destination actually belongs to the same route
929 the sender belongs (ie, we must not resend the packet to the
930 sender). Affected file silcd/packet_send.[ch].
932 * Added `servername' field to the SilcClientEntry in the server
933 to hold the name of the server where client is from. Affected
934 file is silcd/idlist.h.
936 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Moved the channel message encrypting in the router betwen
939 router connections from silc_server_channel_message to the
940 silc_server_packet_relay_to_channel since we want to check
941 whether we have anybody channel before encrypting anything.
942 Affected files silcd/packet_[receive/send].c.
944 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Fixed the [AdminConnection] server config section to support
947 multiple entries. Affected file silcd/serverconfig.c.
949 * Added support into the server to check the validity of the
950 incoming connection before executing any KE or authentication
953 * The connection configuration is now saved to the KE and
954 connection auth protocol contexts and not fetched anymore in
955 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
957 * The local hosts listenning address and port is also resolved
958 now when starting the server. We want to have the socket object
959 to include the real address and port for the listener. Added
960 new function silc_net_check_local_by_sock into the files
961 lib/silcutil/silcnet.[ch].
963 * Fixed a broadcast bug in server -> do not broadcast if we
966 * Fixed a routing bug. Do not route broadcast packets ever.
967 Broadcast packets must be processed always and not routed since
968 they may be destined to some other host than yourself and thus
969 would get routed without no good reason. Affected file is
972 * Added function silc_server_config_is_primary_route to check
973 whether primary router connection has been configured (a router
974 configuration that we are initiating). If there is not, we
975 will assume that there is only two routers in the SILC network
976 and we will use the incoming router connection as our primary
977 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
979 * Changed the order of the broadcasting. Broadcast _after_ the
980 packet has been processed not before. Affected file is
983 * Fixed a [ClientConnection] parsing bug. The port was never
984 parsed correctly thus resulting to port 0. Affected file
985 silcd/serverconfig.c.
987 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
988 argument and did not set the broadcast packet flag. Affected
989 file silcd/packet_send.c. Fixed same bug in the function
990 silc_server_send_notify as well.
992 * If we receive NEW_ID packet for our own ID in the server, ignore
995 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Removed the nickname from the Private Message Payload.
1000 Updated the code and the protocol specs.
1002 * Updated protocol specs for submitting to the IETF.
1004 * Tweaked the Random Number Generator a bit. Affected file
1005 lib/silccrypt/silcrng.c. Exported a new function
1006 silc_rng_[global]_add_noise which can be used to add more
1009 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1011 * Do not parse packets with different timeout when protocol
1012 is active -> may cause problem with rekey. Affected file
1015 * When server receives signoff notify it must not create
1016 new channel key if the client is on any channels since the
1017 sender of the signoff notify will create it.
1019 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1021 * Added printing of error messages during SKE protocol from the
1022 failure packet sent by server during SKE. Affected file
1025 * Removed the client's failure_callback handling with timeout
1026 and handle it immediately when received.
1028 * The SKE library returned wrong type in SUCCESS and FAILURE
1029 packets. They must be 32 bit MSB not 16 bit MSB.
1031 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Ok, rewrote the logic of the re-key and now it seems to work.
1034 I tested it on high traffic with frequent re-keys without
1035 problems. Added hmac_receive (and renamed hmac to hmac_send)
1036 in SilcClientConnection in lib/silcclient/client.h and
1037 in SilcIDListData in silcd/idlist.h. Also, removed the
1038 SilcPacketParserContext's cipher and hmac fields as they are
1039 not needed anymore and actually caused some problems when
1040 the ciphers and hmac's changed underneath the packet parser.
1042 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1044 * If re-key protocol is active then process the incoming packets
1045 synchronously since we must assure that icoming packets encrypted
1046 with the old key is processed before the new keys is set to
1047 use. This is true other packets than for REKEY packets.
1048 Affected file silcd/server.c. The same was done to client library
1049 as well, affected file lib/silcclient/client.c.
1051 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Fixed bug in client and server to accept the force send if
1054 the packet is send from silc_[server/client]_packet_process
1055 function. Otherwise the packets are never delivered, oops.
1057 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Disable force sending of packets when REKEY protocol is active.
1060 We must assure that no packet is sent directly when rekey is
1061 performed. All packets must be sent through packet queue.
1062 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1063 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1064 function is silc_[server/client]_packet_send_real to check
1067 * Replaced the SIM paths from example config files to
1068 /usr/local/modules. Also, make install creates now
1069 /usr/local/silc/logs directory to hold all the SILC server
1072 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Made the configure.in.pre work on Solaris. Patch by salo.
1076 * Made all ciphers compatible with non-x86 machines. Defined
1077 CBC mode macros into lib/silccrypt/ciphers_def.h.
1079 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * Fixed the make install.
1083 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * When MAC computation fails the silc_packet_decrypt returned 0
1086 even though it was supposed to return -1. Fixed this. The
1087 affected file is lib/silccore/silcpacket.c.
1089 * Do not replace the config files in /etc/silc (in make install)
1090 if they already exist. Affected file ./Makefile.am.
1092 * Do not send re-key packets immediately but through packet queue.
1093 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1095 * Changed silc_net_check_host_by_sock to return FALSE if the
1096 IP/DNS could not be resolved. Though, it returns the IP address
1097 now even if it could not resolve it (but returns also FALSE).
1098 Affected file lib/silcutil/silcnet.[ch].
1100 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1102 * Added silc_pkcs_decode_identifier to decode the public key's
1103 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1104 Added also silc_pkcs_free_identifier. Added also new context
1105 SilcPublicKeyIdentifier.
1107 * Added -S option to the silc client. It is used to dump the
1108 contents of the specified public key file.
1110 * Changed the PKCS api to return the public key length when
1111 setting the public key.
1113 * Fixed a fatal bug in the public and private key file loading.
1114 Affected file lib/silccrypt/silcpkcs.c.
1116 * Execute the packet parsing for client with zero (0) timeout
1117 if the protocol is active. Affected file silcd/server.c.
1119 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Made the key generation options to the silcd program. Added
1122 -C option, equivalent to client's option.
1124 * Added new [ServerKeys] config section to the server. It
1125 configures the server's public and private key.
1127 * Defined generic Public Key Payload into the protocol
1128 specification to send specific type of public keys and
1131 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1132 public key or certificate.
1134 * Implemented the GETKEY command to the server and to the
1135 client library and on user interface.
1137 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Made preliminary `make install' work.
1141 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Added SilcServerRekey context into silcd/idlist.h.
1145 * Added the PFS support as defined in the specification to the
1146 SKE protocol. Affected files lib/silcske/*.c.
1148 * Added `ske_group' field to the SilcServerRekey context to hold
1149 the number of the SKE group that is used with PFS in re-key.
1150 Affected file silcd/idlist.h.
1152 * Added PFS re-key support to the server. Affected file is
1155 * Added silc_protocol_cancel to cancel execution of the next
1156 state of the protocol. Affected file is
1157 lib/silccore/silcprotocol.[ch].
1159 * Added the re-key support with and without PFS to the client
1160 library. Re-key is performed once in an hour, by default.
1162 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1163 Added silc_client_rekey_callback and silc_client_rekey_final.
1164 Affected files are lib/silcclient/protocol.[ch] and
1165 lib/silcclient/client.[ch].
1167 * Removed the `hmac_key' and `hmac_key_len' fields from the
1168 SilcClientConnection structure; not needed. Affected file is
1169 lib/silcclient/client.h.
1173 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Do not ask whether user wants to use the negotiated private key
1176 for private messages, just use it. Affected file is
1177 silc/local_command.c.
1179 * Added `send_enc_key' and `enc_key_len' fields to the
1180 SilcIDListData structure since they are needed in the re-key
1181 phase. Affected file is silcd/idlist.[ch].
1183 * Implemented the simple re-key protocol into the server.
1184 Affected files silcd/server.c and silcd/protocol.[ch]. The
1185 re-key will be performed once in an hour, by default.
1187 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1188 Added silc_server_rekey, silc_server_rekey_callback and
1189 silc_server_rekey_final.
1191 * Removed Tunneled flag from the protocol. Updated the code
1192 and the specifications.
1194 * Adde `pfs' field to the SilcIDListData to indicate whether
1195 the PFS is to be performed in the re-key. Affected file is
1198 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1200 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1201 int64 of at least the xintXX size. If void * is less that 4
1202 bytes uint32 * will be used. Defined bool as boolean.
1204 * Changed _ALL_ unsigned long and unsigned int to uint32,
1205 unsgined short to uint16 in the source tree.
1207 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1208 not handle clients that has entry->data.registered == FALSE.
1209 They are not in the network anymore. Affected file is
1212 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * Implemented the sending of the SERVER_SIGNOFF notify in the
1215 server. Affected file is silcd/server.c.
1217 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1218 Added also silc_notify_payload_encode_args into the
1219 lib/silccore/silcnotify.[ch].
1221 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1222 Affected file silcd/packet_receive.c.
1224 * Implemented the SERVER_SIGNOFF notify handling in the client
1225 library. Affected file lib/silcclient/client_notify.c. Also,
1226 implemnted the printing of the SERVER_SIGNOFF info to the
1227 application. Affected file silc/client_ops.c.
1229 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1230 if the deleting was successful. Affected file silcd/idlist.[ch].
1232 * Added support for public key authentication in the connection
1233 authentication protocol in the client library. Affected file
1234 lib/silcclient/protocol.c.
1236 * Changed the server's silc_idlist_get_clients_by_* interface
1237 to support already allocated array so that new entries may be
1238 added to pre-allocated array. Affected file silcd/idlist.[ch].
1239 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1240 and command replies.
1242 * All command reply functions in the server now calls the
1243 pending command callback even if error occured. This way the
1244 error will be delivered to the client as well. Affected files
1245 silcd/command.c and silcd/command_reply.c.
1247 * Fixed INFO command to return local server's info if no server
1248 was provided. Affected file lib/silcclient/command.c.
1250 * Removed RESTART command for good. Updated the code and the
1253 * Rewrote parts of the task system. It is a bit simpler now.
1254 Removed unsued task priorities. The affected files are
1255 lib/silcutil/silctask.[ch].
1257 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Moved the USERS printing from the library to the application.
1260 Affected files lib/silcclient/command.c and silc/client_ops.c.
1262 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Added channel key re-key support. The re-key is perfomed
1267 only by the router and is done once in an hour. Added `rekey'
1268 field to the SilcChannelEntry in the server. Affected files
1269 silcd/server.c and silcd/idlist.h.
1271 * Added silc_task_unregister_by_context into the file
1272 lib/silcutil/silctask.[ch].
1274 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * Added SILC_UMODE_GONE mode to indicate when the client is not
1277 present in the SILC network. Added also support to the local
1278 command AWAY that will set this mode. Added support of showing
1279 "xxx is gone" in WHOIS command. The USERS command shows the
1280 gone status as well.
1282 * Fixed setting server and router operator privileges in the
1283 server's UMODE command. Affected file silcd/command.c.
1285 * Merged the SKE KE1 and KE2 payloads into one payload. The
1286 new KE payload is equivalent to the old KE2 payload.
1288 Cleaned up the SKE Start Payload parsing. It now uses the
1289 simple buffer unformatting to do the parsing. A lot faster
1292 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1293 to the SKE that is used to indicate whether both of the SKE
1294 parties should perform authentication. By default only the
1295 responder performs authentication. By setting this flag also
1296 the initiator must do authentication. By default it is unset
1297 since in normal SKE case, client to server connection, only
1298 the responder should do authentication. When doing SKE between
1299 two clients both should perform authentication. Updated the
1300 code and the protocol specs.
1302 * A little fix to IDENTIFY command in the server. Search the
1303 client first by hash not nickname. Affected file is
1306 * Fixed the silc_client_close_connection to support closing
1307 the client to client connections wihtout deleting too much
1308 data. Affected file lib/silcclient/client.c.
1310 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1311 are received if protocol used to be active but is not anymore
1312 the application would crash due to NULL pointer dereference.
1313 Affected files silcd/server.c and lib/silcclient/client.c.
1315 * Added `hash' field to the SilcClientConnection to include
1316 the hash function negotiated in the SKE protocol.
1318 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1319 to set the channel founder authentication data. A client can
1320 claim the founder rights later by providing the authentication
1321 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1322 This way the channel founder can regain the channel founder
1323 privileges even it is left the channel. This works only on
1324 local server and the client must be connected to the same
1325 server to be able to regain the founder rights. Updated the
1326 protocol specs accordingly.
1328 Added support to the CMODE command in the client to set the
1329 founder auth data. Read the README to see how to set it.
1331 Added support to the CUMODE command to claim the founder
1332 rights. Read the README to see how to do it.
1334 Added support for the founder authentication to the Channel
1335 Entry in the server. Affected file silcd/idlist.h.
1337 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1338 server's CMODE command. Affected file silcd/command.c.
1340 * Added the following new functions into lib/silccore/silcauth.[ch]:
1341 silc_auth_get_method and silc_auth_get_data.
1343 * The server now saves the remote hosts public key to the
1344 SilcIDListData pointer. Affected file silcd/protocol.c.
1346 * The normal server now does not remove the channel entry from
1347 the cache if the founder authentication data is set. It used
1348 to remove it if the founder was the last one on the channel on
1349 the server and left the channel. The auth data is saved and
1350 if the channel is re-joined later the old entry is used with
1351 the old auth data. Affected files silcd/command_reply.c and
1354 * Removed the `pkcs' field from the SilcIDListData structure
1355 in the server; it is not used. Affected file silcd/idlist.h.
1357 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Fixed packet processing on slow links. Partial packets were
1360 never re-processed because the incoming data buffer was cleared
1361 by the application. Application must not directly clear the
1362 sock->inbuf, the packet processing routines handle it. Fixed
1363 this in client library and in server.
1365 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Fixed the WHOIS and IDENTIFY send reply function to really
1368 check whether to send list or just one entry. Affected file
1371 * Cleaned up the LEAVE command's channel key distribution. The
1372 affected file silcd/command.c.
1374 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1375 can enforce the channel mode as well. In that case the ID
1376 includes the ID of the server. The code now enforces the
1377 mode change if the router have different mode than the server.
1379 * The notify client operation with CMODE_CHANGE notify can now
1380 return NULL client_entry pointer if the CMODE was not changed
1381 by client. Application must check for this.
1383 * Added <Server ID> argument to INFO command to support server
1384 info fetching by Server ID.
1386 * Added silc_server_announce_get_channel_users to get assembled
1387 packets of channel users of the specified channel. Affected
1388 file silcd/server.[ch].
1390 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1391 was freed underneath the ID Cache.
1393 * Re-announce clients when the server received CHANNEL_CHANGE
1394 notify from the router. Affected file silcd/packet_send.c.
1396 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1399 crashed since it did not handle the fact that there is no cipher
1400 called "3" and didn't check the error condition. Now fixed.
1402 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1403 flag. It can be used to send message requests.
1405 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Implemented the RESTART command in the client.
1409 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1410 notice type messages. Added notice printing to the user
1413 * The channel keys are not re-generated if the channel's mode
1414 is PRIVKEY, ie private key on the channel exists. Affected
1415 files silcd/server.c and silcd/command.c.
1417 * Fixed a little bug in channel message delivery when channel
1418 private keys are set in the server. Affected file is
1419 silcd/packet_send.c.
1421 * Changed the setting on channel->on_channel = TRUE from the
1422 silc_client_save_channel_key to the JOIN command reply. The
1423 key payload is not received if the private channel key is set.
1424 Affected file lib/silcclient/command_reply.c and the
1425 lib/silcclient/client_channel.c.
1427 * When the CMODE_CHANGE notify is sent and the channel private
1428 key mode is removed the channel key must be re-generated in
1429 other cells as well. Added this support for the router in the
1430 silcd/packet_receive.c.
1432 * Added new local command NOTICE to send notice message on
1433 channel. Affected file silc/local_command.[ch].
1435 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1437 * Added new local command ME to the client. It is used to send
1438 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1439 some action. Affected file silc/local_command.[ch].
1441 * Changed channel_message and private_message client operations
1442 to deliver the message flags to the application. Added also
1443 the `flags' arguments to the silc_client_send_channel_message
1444 and silc_client_send_private_message functions. Affected file
1447 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Redefined the Private Message Payload to support private message
1450 keys and to support the new private message flags. Updated
1451 the protocol specs. Flags makes it possible to have for example
1452 CTCP style messages.
1454 * Added new type SilcPrivateMessagePayload and defined an API
1455 for it in the lib/silcclient/silcprivate.[ch].
1457 * Tested private message private keys successfully. Tested the
1458 private message key set, unset and list commands with the new
1461 * Redefined the Channel Message Payload to include the channel
1462 message flags (equal with private message flags) to support
1463 for example CTCP style messages.
1465 * Defined some of the message (for channel and private message)
1466 flags. Updated the protocol specs and added the flags to the
1467 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1469 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Added SilcKeyAgreementStatus type to the key agreement routines
1472 to indicate the current status and error if one occured.
1473 The status types are defined in the lib/silcclient/silcapi.h.
1475 * Added new local command KEY that is used to set and unset private
1476 keys for channels, set and unset private keys for private messages
1477 with remote clients and to send key agreement requests and
1478 negotiate the key agreement protocol with remote client. The
1479 key agreement is supported only to negotiate private message keys,
1480 it currently cannot be used to negotiate private keys for channels,
1481 as it is not convenient for that purpose.
1483 * Fixed a minor pending callback setting bug in the function
1484 silc_client_get_client_by_id_resolve, now the function works.
1485 Affected file lib/silcclient/idlist.c.
1487 * Added function silc_net_get_local_port to get local bound
1488 port by socket. Added to lib/silcutil/silcnet.[ch].
1490 * Added `sockets' and `sockets_count' fields to the SilcClient
1491 object. They hold the sockets of the listenning sockets in
1492 the client. Listenning sockets may be for example the key
1493 agreement server. Affected file lib/silcclient/client.[ch].
1494 Added functions the silc_client_add_socket and the
1495 silc_client_del_socket. They are exported to the application
1498 * Added ~./silc/clientkeys to support other client's public keys.
1500 * Renamed verify_server_key client operation to verify_public_key
1501 and added one argument to indicate the type of the connection
1502 (server, client etc.).
1504 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Added silc_server_connection_auth_request to handle the
1507 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1508 silcd/packet_receive.[ch].
1510 * Added silc_server_send_connection_auth_request into the
1511 silcd/packet_send.c to send the connection auth request packet.
1513 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1516 * Fixed the public key authentication in responder side in the
1517 server. The `auth_data' pointer includes the SilcPublicKey
1518 not the path to the public key. Affected file silcd/protocol.c.
1520 * Implemented the public key authentication in the initiator side
1521 in the server. Affected file silcd/protocol.c.
1523 * Removed the [RedirectClient] config section from the server
1524 configuration. Is not needed and I don't want to implement it.
1526 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Cleaned up the CMODE command in the server. It now works
1529 correctly and supports all the modes defined in the protocol.
1530 Affected file is silcd/command.c.
1532 * Added `hmac_name' field to the SilcChannelEntry in the server
1533 to hold the default HMAC of the channel. It can be set when
1534 creating the channel (with JOIN command). Affected files
1537 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1538 type to indicate the change of the current cipher and hmac
1539 on the channel. Client can safely ignore the <cipher> argument
1540 (if it chooses to do so) since the CHANNEL_KEY packet will
1541 force the channel key change anyway. The <hmac> argument is
1542 important since the client is responsible of setting the new
1543 HMAC and the hmac key into use.
1545 * Fixed the CMODE command in the client library as well.
1547 * Tested CMODE command in router environment successfully.
1549 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Show the version of the remote client (or server) when connecting
1552 to the server. It is logged to the log file. Affected file
1553 is silcd/protocol.c.
1555 * Fixed the KILLED notify handling in the client library. The
1556 client must be removed from all channels when receiving the
1559 Also, do not remove the client entry when giving the KILL
1560 command but when the KILLED notify is received.
1562 * Removed silc_idlist_find_client_by_nickname from the server.
1563 Not needed anymore. Affected files silcd/idlist.[ch].
1565 * Implemented the CHANNEL_CHANGE notify type handling to the
1566 server. Affected file silcd/server.c.
1570 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1572 * Added silc_server_send_notify_invite to send the INVITE
1573 notify between routers.
1575 * Implemented the INVITE command correctly to the server.
1577 * Implemented the INVITE notify type handling in the server.
1579 * Implemented the INVITE command to the client library and on the
1582 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Added function silc_server_get_client_resolve to find the
1585 client entry by ID from all ID lists and then resolve it
1586 (using WHOIS) if it cannot be found. Affected file is
1589 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1591 * Implemented the BAN command to the client library.
1593 * The JOIN command in the server now checks the invite list
1596 * Changed the silc_command_reply_payload_encode_va and the
1597 silc_command_payload_encode_va to support that if argument is
1598 NULL it ignores and checks the next argument. Affected file
1599 lib/silccore/silccommand.c.
1601 * Added silc_server_send_notify_ban to send the BAN notify
1602 type between routers.
1604 * Chaned the silc_notify_payload_encode to support that if
1605 argument is NULL it ignores and checks the next argument.
1606 Affected file lib/silccore/silcnotify.c.
1608 * Tested ban lists in router environment successfully.
1610 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Implemented BAN command to the server, in silcd/command.[ch].
1614 * Removed the BAN and INVITE_LIST modes from the CMODE command
1617 * Added function silc_string_match to regex match two strings.
1618 Affected files lib/silcutil/silcutil.[ch].
1620 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * Redefined parts of the SilcChannelEntry in the server to support
1623 the new ban and invite lists.
1625 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Redefined the INVITE command. The same command can be used to
1628 invite individuals to the channel but also to manage the invite
1629 list of the channel (to add to and remove from the invite list).
1630 Updated the protocol specs.
1632 * Added new command SILC_COMMAND_BAN that can be used to manage
1633 the ban list of the channel. Updated the protocol specs.
1635 * Removed the channel modes: the SILC_CMODE_BAN and the
1636 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1637 in the CMODE command. The equivalent features are now available
1638 using INVITE and BAN commands. Updated the protocol specs.
1640 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1641 in the network about change in the current ban list. The notify
1642 type is not used by the client.
1644 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1645 support the invite lists.
1647 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Added new function silc_string_regexify that converts string
1650 including wildcard characters into regex string that can
1651 be used by the GNU regex library. Added into the file
1652 lib/silcutil/silcutil.[ch].
1654 Added silc_string_regex_combine to combine to regex strings
1655 into one so that they can be used as one regex string by
1656 the GNU regex library. Added into the file
1657 lib/silcutil/silcutil.[ch].
1659 Added silc_string_regex_match to match two strings. It returns
1660 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1662 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Imported GNU regex to the soruce tree into lib/contrib.
1665 Fixed some compiler warning from the regex.c.
1667 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1669 * Fixed MOTD command in the server to work in router environment.
1671 * Fixed the MOTD command in the client library to support
1672 the server argument in the command.
1674 * Added `nickname_len' argument to the silc_idlist_add_client
1675 in the server, as the `nickname' argument may be binary data
1678 * Added silc_idlist_get_channels to return all channels from
1681 * Implemented LIST command to the server. Affected file is
1684 * Implemented the LIST command to the client library and on the
1687 * Added [<user count>] argument to the LIST command reply.
1688 With private channels the user count is not shown.
1690 * Updated TODO and README.
1692 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * The client entry's data.registered must be TRUE even with
1695 global client entry on global client list. The data.registered
1696 is used to check whether the client is anymore in the network,
1697 for example with WHOWAS command so it must be valid.
1699 * Fixed the WHOWAS command in the server. It now actually works
1700 in router environment. Added function into silcd/command_reply.c
1701 silc_server_command_reply_whowas_save.
1703 * Added silc_idlist_purge function to the silcd/idlist.c
1704 to periodically purge the ID Cache.
1706 * Fixed INFO command in the server. It works now in router
1707 environment. Added <server name> argument to the INFO command
1708 reply. Updated the protocol specs.
1710 * Fixed minor bug in silc_idcache_purge to not purge if the
1711 expire value is zero.
1713 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1714 they were buggy because of the WHOWAS information.
1716 * Fixed local command MSG to handle the async resolving of
1717 the remote client properly. It used to fail the first MSG.
1718 Affected file silc/local_command.c.
1720 * Added `data_len' field to SilcIDCache context.
1722 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1724 * Update TODO. Todo in commands in the server.
1726 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1728 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1729 used by routers as broadcast packet to inform other routers
1730 about the changed user mode.
1732 Implemented the notify handling in the server. Affected file is
1733 silcd/packet_receive.c. Added the function
1734 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1736 * Added new generic Channel Payload and deprecated the New Channel
1737 Payload. The New Channel Payload is now the generic Channel
1740 * Added new argument `mode' to the silc_server_send_new_channel
1741 as it is required in the Channel Payload now.
1743 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1744 and created a new and real SilChannelPayload to represent the
1745 new generic Channel Payload. Implemented the encode/decode
1746 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1748 * Added silc_server_get_client_channel_list to return the list
1749 of channels the client has joined for WHOIS command reply.
1750 Affected file silcd/server.[ch].
1752 * Implemented the channel list sending in the WHOIS command reply
1753 in server and in the client.
1755 Implemented the channel list displaying on the user interface
1756 as well. Affected file silc/client_ops.c.
1758 * Added silc_channel_payload_parse_list to parse list of Channel
1759 Payloads. It returns SilcDList list of SilcChannelPayloads.
1760 Client for example can use this function to parse the list of
1761 channels it receives in the WHOIS command reply. The caller
1762 must free the list by calling silc_channel_payload_list_free.
1763 Affected files lib/silccore/silcchannel.[ch].
1765 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Added one new argument <user mode> to the WHOIS command reply
1768 to return the mode of the user in SILC. Updated the protocol
1771 Implemented it to the server and client.
1773 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Fixed the mode printing on the user interface on joining.
1776 Affected file silc/client_ops.c.
1778 * Implemented the UMODE command and user modes in general to the
1779 client library and to the user interface.
1781 * Implemented the UMODE command to the server.
1783 * The server now sends UNKNOWN_COMMAND error status if client sends
1784 unknown command. Affected file silcd/command.c.
1786 * All server commands now handle the command identifier the right
1787 way when sending the command reply to the client. The client can
1788 use to identify the command replies with the identifier.
1790 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Added silc_server_get_client_route to resolve the route to
1793 the client indicated by the client ID. Affected file is
1796 * Added silc_server_relay_packet as general function to relay
1797 packet to arbitrary destination. This deprecates functions
1798 like _send_private_message_key, _relay_notify etc. Affected
1799 file is silcd/packet_send.[ch].
1801 Removed silc_server_send_key_agreement,
1802 silc_server_send_private_message_key and
1803 silc_server_packet_relay_notify functions from the file
1804 silcd/packet_send.[ch].
1808 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1809 server. Affected file silcd/packet_receive.[ch].
1811 * Implemented the KILL command to the client. Implemented the
1812 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1813 Affected files lib/silcclient/command[_reply].c and
1814 lib/silcclient/client_notify.c. Implemented the KILL notify
1815 printing in the user inteface.
1817 * Fixed a lot silc_parse_nick memory leaks from the client
1818 library in the file lib/silcclient/command.c.
1820 * Changed the silc_server_send_notify_on_channels's `sender'
1821 argument from SilcSocketConnection to SilcClientEntry to
1822 check the sender as entry and not as connection object and not
1823 to send to the client provided as argument. The affected file
1824 is silcd/packet_send.[ch].
1826 * The notify packets that are destined directly to the client used
1827 to not to be processed by the server. Now changed that and the
1828 server processes all notify packets. After relaying the packet
1829 to the client the notify packet is processed in the server.
1831 * The silc_server_free_client_data now checks whether there is
1832 pending outgoing traffic for the client and purges the data to
1833 the network before removing the client entry.
1835 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1838 an client is killed from the SILC Network. Updated the protocol
1841 Added new function silc_server_send_notify_killed to the
1842 silcd/packet_send.[ch].
1844 * Added function silc_server_packet_relay_notify to relay notify
1845 packets that are destined directly to a client. In this case
1846 the server does not process the notify packets but merely relays
1847 it to the client. Affected file silcd/packet_send.[ch].
1849 Added also silc_server_packet_process_relay_notify to check
1850 whereto relay the notify. Affected file is
1851 silcd/packet_receive.[ch].
1853 * Implemented the KILL command to the server.
1857 * Added the backup schema desgined last fall to the protocol
1858 specs for everyone to see. The specification is in the
1859 *-spec-xx.txt draft and the packet type definitions for the
1860 backup routers is in *-pp-xx.txt draft. Thusly, added also
1861 new packet type SILC_PACKET_CELL_ROUTERS.
1863 * A big security problem in the implementation discovered. The
1864 signoff of an client did not cause new channel key generation
1865 which it of course should've done. The channel keys must be
1866 always re-generated when client leaves (or signoffs) the channel.
1867 The silc_server_remove_from_channels funtion now handles
1868 the channel key re-generation.
1870 * Added `sender' argument to the silc_server_send_notify_on_channels
1871 to not to send the client provided as argument. Affected file
1872 silcd/packet_send.[ch].
1874 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Implemented OPER and SILCOPER commands into the server and
1879 * Added silc_auth_verify and silc_auth_verify_data to verify
1880 the authentication directly from the authentication payload.
1881 It supports verifying both passphrase and public key based
1882 authentication. Affected file lib/silccore/silcauth.[ch].
1884 * Added `hash' field to the SilcIDListData structure. It is the
1885 hash negotiated in the SKE protocol. Affected file is
1888 * Slight redesigning of the SilcAuthPayload handling routines.
1889 Do not send SilcPKCS but SilcPublicKey as argument.
1891 * Implemented the public key authentication support to the
1892 serverconfig. The public key is loaded from the provided path
1893 and saved as authentication data to void * pointer. Thus,
1894 changed the unsigned char *auth_data to void *auth_data;
1896 * Fixed SHUTDOWN command to send the reply before the server
1897 is shutdown. :) Affected file silcd/command.c.
1899 * Fixed fatal bug in CONNECT command. The hostname was invalid
1900 memory and server crashed. Affected file silcd/command.c.
1902 * Fixed fatal bug in CLOSE command. The server_entry became
1903 invalid but was referenced later in the command. Affected file
1906 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Fixed fatal bug in failure packet handling. Server ignored
1909 the failure and thus crashed when it came.
1913 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1916 that the command may be executed only once in (about) 2 seconds.
1917 The old SILC_CF_LAG flag is same but allows command bursts up
1918 to five before limiting.
1920 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1921 server code. Various commands now includes the CF_LAG_STRICT
1922 flag to disallow any kind of miss-use of the command.
1924 * Fixed the silc_buffer_unformat to not to allocate any data
1925 if the length of the data is zero. It used to allocate the
1926 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1928 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1930 * Changed the format of AdminConnection configuration section
1931 in the server. Added username of the admin to the format.
1932 Affected files silcd/serverconfig.[ch].
1934 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1935 to return admin configuration data by host, username and/or
1938 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Implemented WHOWAS command to the server. Added the functions:
1942 silc_server_command_whowas_parse,
1943 silc_server_command_whowas_send_reply,
1944 silc_server_command_whowas_from_client and
1945 silc_server_command_whowas_from_server
1947 * Added <Client ID> argument to the WHOWAS command reply. Updated
1948 the protocol specs accordingly.
1950 * Implemented WHOWAS command and command_reply to the client
1953 Implemented the WHOWAS printing on the user interface.
1955 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Added new argument to the WHOWAS command reply, the real name.
1958 It is an optional argument. Updated the protocol specs.
1960 * Added SilcIDCacheDestructor callback that is registered when
1961 the SilcIDCache is allocated. The callback is called when
1962 an cache entry in the ID Cache expires, or is purged from the
1963 cache. Added into lib/silccore/idcache.[ch].
1965 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1966 to destruct the client entries when the cache entry expires.
1967 Other ID Cache's in server and in the client library ignores
1970 * If the ID Cache entry's `expire' field is zero then the entry
1971 never expires. Added boolean `expire' argument to the
1972 silc_idcache_add function in the lib/silccore/idcache.[ch].
1973 If it is TRUE the default expiry value is used.
1975 * Added silc_server_free_client_data_timeout that is registered
1976 when client disconnects. By default for 5 minutes we preserve
1977 the client entry for history - for WHOWAS command.
1979 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Added support to the server to enforce that commands are not
1982 executed more than once in 2 seconds. If server receives
1983 commands from client more frequently, timeout is registered
1984 to process the commands. Affected file silcd/command.c.
1985 Added new function silc_server_command_process_timeout.
1987 * Changed NICK_NOTIFY handling in client library to check that
1988 if the client's nickname was changed, so there is no need to
1989 resolve anything from the server.
1991 * Removed error printing from the WHOIS and IDENTIFY commands.
1992 If error occurs then it is ignored silently in the client library.
1993 The application, however, may map the received error to
1994 human readable error string. The application currently maps
1995 the NO_SUCH_NICKNAME error to string.
1997 * Made the command status message public to the application. Moved
1998 them from lib/silcclient/command_reply.c to
1999 lib/silcclient/command_reply.h. The application can map the
2000 received command status to the string with the
2001 silc_client_command_status_message function.
2003 * Added check to the server to check that client's ID is same
2004 as the Source ID in the packet the client sent. They must
2007 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Added dist-bzip hook to the Makefile.am to make bzip2
2010 compressed distributions.
2012 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Server now enforces the maximum length for the nickname and
2015 the channel as protocol specification dictates. 128 bytes for
2016 nickname and 256 bytes for channel name.
2018 * Moved the WHOIS printing to the application. The client libary
2019 does not print out the WHOIS information anymore, the application
2020 must do it. Renamed silc_client_command_reply_whois_print to
2021 the silc_client_command_reply_whois_save.
2023 The client's idle time is also sent to the application now, and
2024 the idle is shown on screen.
2026 * Added silc_client_command_reply_identify_save to save the
2027 received IDENTIFY entries.
2029 * Do not check for channel private keys in message sending and
2030 reception if the channel does not have the PRIVKEY mode set.
2031 Affected file lib/silclient/client_channel.c.
2033 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2036 just surfaced after chaning the JOIN procedure.
2038 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2040 * Added silc_client_get_clients_by_list to get client entries
2041 from Client ID list, that is returned for example by JOIN
2042 and USERS command replies. The application should use this
2043 function for example when JOIN command reply is received to
2044 resolve the clients already on the channel (library does not
2045 do that anymore as USERS command reply is not used in the JOIN
2046 procedure anymore). Affected files lib/silcclient/silcapi.h and
2047 lib/silcclient/idlist.c.
2049 * JOIN command reply and USERS command reply returns now SilcBuffer
2050 pointers instead of unsigned char pointers when returning
2051 the client list and mode list.
2053 * Added <Client ID> argument to the JOIN command reply, mainly
2054 for the server to identify for which client the command was
2055 originally sent. Updated protocol specs accordingly.
2057 * Added SilcDlist private_key pointer to the SilcChannelEntry
2058 in the client to support the channel private keys. Affected
2059 file is lib/silcclient/idlist.h.
2061 * Added SilcChannelPrivateKey argument to the function
2062 silc_client_send_channel_message so that application can choose
2063 to use specific private ke if it wants to. If it is not provided,
2064 the normal channel key is used, unless private keys are set.
2065 In this case the first (key that was added first) is used
2066 as the encryption key.
2068 * Implemented the support for channel private key handling.
2069 Implemented the following functions:
2071 silc_client_add_channel_private_key,
2072 silc_client_del_channel_private_keys,
2073 silc_client_del_channel_private_key,
2074 silc_client_list_channel_private_keys and
2075 silc_client_free_channel_private_keys
2077 Affected file lib/silcclient/client_channel.c.
2079 * Added the support for the private keys in the channel message
2080 sending and encryption and in the message reception and
2081 decryption. Affected funtions are
2082 silc_client_send_channel_message and silc_client_channel_message.
2084 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added SKE's key verify callback to the client library's
2087 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2089 * Removed the statement that server (or router) must send USERS
2090 command reply when joining to the channel so that the client
2091 knows who are on the channel. Instead, the client list and
2092 client's mode list is now sent in the JOIN command reply to the
2093 client who joined channel. This is better solution.
2095 * Added function silc_server_get_users_on_channel and function
2096 silc_server_save_users_on_channel to the silcd/server.[ch].
2098 * Removed function silc_server_command_send_users from the
2101 * Do not show topic on the client library anymore. The topic is
2102 sent in the command reply notify to the application and the
2103 application must show the topic now.
2105 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Added client searching by nickname hash into the IDENTIFY and
2108 WHOIS commands in the server as they were clearly missing from
2109 them. Affected file is silcd/command.c.
2111 * Fixed a bug in private message receiving in the client library.
2112 The remote ID was freed and it wasn't supposed, now it is
2115 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Minor fix to the channel payload; allocate the data area, as it
2118 needs to be of specific length.
2120 * If the key agreement port is zero then the operating
2121 system will define the bound port. Affected files are
2122 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2124 * Added new function silc_channel_payload_decrypt into the file
2125 lib/silccore/silcchannel.[ch].
2127 * Moved the channel message etc, check from silc_packet_decrypt
2128 to applications. The library calls now a generic
2129 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2130 when the packet is either normal or special. This was done to
2131 allow more wide range of checking that was not allowed when
2132 the code was in library. Now applications can do virtually any
2133 checks to the packet and return to the library the decision how
2134 the packet should be processed. Affected files are
2135 lib/silccore/silcpacket.[ch].
2137 Added silc_server_packet_decrypt_check to the server and
2138 silc_client_packet_decrypt_check to the client library.
2140 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2141 to send with specified source and destination information.
2143 * Channel message delivery between routers was broken after the
2144 channel key distribution was fixed earlier. The channel key
2145 was used be to distributed to other routers as well which is not
2146 allowed by the protocol. Now this is fixed and channel keys
2147 really are cell specific and the channel message delivery between
2148 routers comply with the protocol specification.
2150 * Fixed various commands in server to check also the global list
2151 for the channel entry and not just the local list. The affected
2152 file silcd/command.c.
2154 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Added assert()s to buffer formatting and unformatting routines
2157 to assert (if --enable-debug) when error occurs. Affected
2158 file: lib/silcutil/silcbuffmt.c.
2160 * Changed to auto-reconnect to check whether the remote host is
2161 router and register the re-connect timeout if it is. It used
2162 to check that whether we are normal server, but router must do
2163 auto-reconnect with another router as well. Affected file
2166 * Removed the [<key len>] option from CMODE command as the cipher
2167 name decides the key length, nowadays. See the defined ciphers
2168 from the protocol specification.
2170 * Added [<hmac>] option to the CMODE command to define the HMAC
2171 for the channel. Added SILC_CMODE_HMAC channel mode.
2173 * Added [<hmac>] option for the JOIN command so that user can
2174 select which HMAC is used to compute the MACs of the channel
2177 * Added Hmac field to the Channel Message Payload. The integrity
2178 of plaintext channel messages are now protected by computing
2179 MAC of the message and attaching the MAC to the payload. The
2180 MAC is encrypted. Now, it is clear that this causes some
2181 overhead to the size of the packet but rationale for this is that
2182 now the receiver can verify whether the channel message decrypted
2183 correctly and also when private keys are set for the channel the
2184 receiver can decrypt the packet with several keys and check from
2185 the MAC which key decrypted the message correctly.
2187 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2188 lib/silccrypt/silccipher.[ch].
2190 * Added silc_hash_len to return the digest length into the
2191 lib/silcrypt/silchash.[ch].
2193 * Rewrote parts of Silc Channel Payload interface in the
2194 lib/silccore/silcchannel.[ch]. The encode function now also
2195 encrypts the packet and parse function decrypts it.
2197 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Fixed a minor formatting bug in the SKE's key material processing.
2200 It actually might have processed the keys wrong way resulting
2203 * Redefined the mandatory HMAC algorithms and added new algorithms.
2204 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2205 and hmac-md5 truncated to 96 bits. The mandatory is now
2206 hmac-sha1-96. Rest are optional (including the one that used
2207 to be mandatory). Rationale for this is that the truncated HMAC
2208 length is sufficient from security point of view and can actually
2209 make the attack against the HMAC harder. Also, the truncated
2210 HMAC causes less overhead to the packets. See the RFC2104 for
2213 * Added new [hmac] configuration section. The SKE used to use
2214 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2215 is of course wrong. The official names that must be proposed in
2216 the SKE are the ones defined in the protocol specification
2217 (hmac-sha1-96 for example). The user can configure any hmac
2218 using any hash function configured in the [hash] section. At
2219 least, the mandatory must be configured.
2221 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2223 * Added HMAC list to the SKE proposal list. It has now both
2224 hash algorithm list and HMAC list. This makes the protocol
2225 incompatible with previous versions. The SKE now seems to work
2226 the way it is supposed to work, for the first time actually.
2228 * Defined plain Hash algorithms to the protocol specification.
2231 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Implemented support for key agreement packets into the server.
2234 Added functions silc_server_key_agreement and
2235 silc_server_send_key_agreement. Other than these functions,
2236 server has nothing to do with this packet.
2238 * Added support for private message key packets into the server.
2239 Added functions silc_server_private_message_key and
2240 silc_server_send_private_message_key.
2244 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2245 called in the protocol's final callback instead in the END
2246 protocol state. This makes a little more sense and in the same
2247 time in client we can use the same protocol routines for normal
2248 key exchange and to key agreement packet handling as well.
2250 * Added to both client's and server's KE protocol context the
2251 SilcSKEKeyMaterial pointer to save the key material. We will
2252 bring the key material to the protocol's final callback by doing
2253 this. The final callback must free the key material.
2255 * Added SKE's packet_send callback into client's KE protocol
2256 context so that the caller can choose what packet sending function
2257 is used. This way we can use different packet sending when
2258 doing normal SKE when doing key agreement packet handling (in
2259 the key agreement packet handling we do not want to encrypt
2262 * Implemented the responder side of the key agreement routines
2263 in the client. The client can now bind to specified port and
2264 accept incoming key negotiation. The key material is passed
2265 to the application after the protocol is over.
2267 * Implemented the processing of incoming Key Agreement packet
2268 in the client. Added function silc_client_key_agreement to
2271 * Implemented the intiator side of the key agreement routines
2272 in the client. The client can now initiate key agreement with
2273 another remote client. The key material is passed to the
2274 application after the protocol is over.
2276 * Created client_keyagr.c to include all the key agreement
2279 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2280 SILC_TASK_CALLBACK except that it is not static.
2282 * Created client_notify.c and moved the Notify packet handling
2283 from the client.[ch] into that file.
2285 * Created client_prvmsg.c and moved all private message and
2286 private message key routines from the client.[ch] into that file.
2288 * Create client_channel.c and moved all channel message and
2289 channel private key routines from the client.[ch] into that file.
2291 * Changed silc_client_get_client_by_id_resolve to resolve with
2292 WHOIS command instead of IDENTIFY command, in the file
2293 lib/silclient/idlist.c.
2295 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Implemented the SKE's responder side to the Client library.
2299 * When FAILURE is received to the protocol do not trust it
2300 blindly. Register a timeout to wait whether the remote closes
2301 the connection as it should do it, only after that process the
2302 actual failure. This was changed to both client and server.
2304 * Added client_internal.h to include some of the structures
2305 there instead of client.h in lib/silcclient/.
2307 * Added function silc_task_unregister_by_callback to unregister
2308 timeouts by the callback function.
2310 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Some "Incomplete WHOIS info" errors has been appearing on the
2313 log files. Took away the entry->userinfo check from WHOIS
2314 reply sending. The entry->userinfo is now " " if client did not
2315 provide one. I thought this was fixed earlier but something
2316 is wrong still. Let's see if the error still appears.
2318 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Fixed a minor bug in the login when the channel key is
2321 re-generated in the server. It used to generate the key in
2322 wrong order and thus caused problems in the channel traffic.
2324 * Fixed a minor bug in channel key distsribution after
2325 KICK command. The key was not sent to the router even though
2328 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Added silc_ske_process_key_material_data as generic routine
2331 to process any key material as the SILC protocol dictates. The
2332 function is used by the actual SKE library but can be used by
2333 applications as well. This relates to the private message keys
2334 and the channel private keys since they must be processed the
2335 same way the normal SILC session keys. The protocol dictates
2336 this. Affected files: lib/silcske/silcske.[ch].
2338 Added also silc_ske_free_key_material to free the
2339 SilcSKEKeyMaterial structure.
2341 * Defined silc_cipher_set_key function to set the key for
2342 cipher without using the object's method function. The affected
2343 files: lib/silccrypt/silccipher.[ch].
2345 * Implemented silc silc_client_add_private_message_key,
2346 silc_client_add_private_message_key_ske,
2347 silc_client_del_private_message_key,
2348 silc_client_list_private_message_keys and
2349 silc_client_free_private_message_keys functions in the
2352 Added functions silc_client_send_private_message_key to send
2353 the Private Message Key payload and silc_client_private_message_key
2354 to handle incoming Private Message Key payload.
2356 * Added Cipher field to the Private Message Key payload to set
2357 the cipher to be used. If ignored, the default cipher defined
2358 in the SILC protocol (aes-256-cbc) is used.
2360 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Removed lib/silcclient/ops.h file.
2364 Redefined parts of the SILC Client Library API. Created new
2365 file silcapi.h that deprecates the ops.h file and defines the
2366 published Client Library API. Defined also private message key
2367 API and channel private key API into the file.
2369 This is the file that the application must include from the
2370 SILC Client Library. Other files need not be included by
2371 the application anymore.
2373 * Added new key_agreement client operation callback and also
2374 defined the Key Agreement library API for the application.
2376 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2379 is used by clients to request key negotiation between another
2380 client in the SILC network. If the negotiation is started it
2381 is performed using the SKE protocol. The result of the
2382 negotiation, the secret key material, can be used for example
2383 as private message key.
2385 Implemented the Key Agreement payload into the files
2386 lib/silccore/silauth.[ch].
2388 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Redefined ciphers for the SILC protocol. Added some new ciphers
2391 and defined the key lengths for the algorithms. Changed the
2392 code accordingly. The default key length is now 256 bits.
2394 * Fixed SKE key distribution function silc_ske_process_key_material
2395 when the key length is more than 128 bits. The default key
2396 length in SILC is now 256 bits.
2398 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2399 to indicate unsupported algorithm.
2401 * Renamed rijndael.c to aes.c and all functions as well.
2403 * Fixed a long standing channel key setting bug in client library.
2404 Weird that it has never surfaced before.
2406 * Fixed bug in channel deletion. If the entire channel is removed
2407 then it must also delete the references of the channel entry
2408 from the client's channel list as the client's channel entry and
2409 the channel's client entry share same memory.
2411 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Implemented CONNECT and SHUTDOWN commands in the client.
2415 * Implemented CLOSE command to the client.
2417 * Added the function silc_idlist_find_server_by_name into the
2418 files silcd/idlist.[ch].
2420 Added the function silc_idlist_find_server_by_conn into the
2421 files silcd/idlist.[ch].
2423 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * DIE command was renamed to SHUTDOWN. Updated the both code
2428 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2429 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2431 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2434 * Added function silc_server_create_connection function to create
2435 connection to remote router. My server implementation actually
2436 does not allow router to connect to normal server (it expects
2437 that normal server always initiates the connection to the router)
2438 so the CONNECT command is only good for connecting to another
2441 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2444 or some other client was kicked from the channel.
2446 Implemented the handling of the notify type to both client
2449 Implemented silc_server_send_notify_kicked to send the KICKED
2450 notify. It is used to send it to the server's primary router.
2452 * Implemented the KICK command into server and client.
2454 * Added `query' argument to the silc_idlist_get_client function
2455 to indicate whether to query the client from server or not if
2458 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2459 to indicate that the client is not channel founder.
2463 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Removed the rng context from SilcPacketContext structure and
2466 changed that the packet routine uses the Global RNG API.
2468 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Added support for quit message that client can "leave" on the
2471 channel when it quits the SILC. It is ditributed inside the
2472 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2474 Added silc_server_free_client_data that will take the
2475 signoff message as argument.
2477 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2479 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Updated parts of the protocol specification to keep it up
2484 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2487 payloads in one packet.
2489 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2490 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2491 use now the new List flag.
2493 * Also deprecated the following packet types: REPLACE_ID,
2494 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2496 * Added list support for Notify packet in server.
2498 * Added silc_server_send_notify_channel_change to send the
2499 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2500 the silc_server_send_replace_id.
2502 * Added silc_server_send_notify_nick_change to send the
2503 NICK_CHANGE notify type. Deprecates the function
2504 silc_server_send_replace_id.
2506 * Added silc_server_send_notify_join to send the JOIN notify type.
2507 Deprecates the function silc_server_send_new_channel_user.
2509 * Added silc_server_send_notify_leave to send LEAVE notify type.
2510 Deprecates the function silc_server_send_remove_channel_user.
2512 * Added silc_server_send_notify_cmode and
2513 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2514 types. Deprecates the silc_server_send_set_mode function.
2516 * Added SERVER_SIGNOFF notify type to indicate that server has
2517 quit. This means that all clients on the channel from that
2518 server will drop. This can be also used when netsplit happens.
2520 Deprecated REMOVE_ID packet type since it is not needed anymore
2523 Added silc_server_send_notify_server_signoff to send the
2524 SERVER_SIGNOFF notify type. Deprecates the function
2525 silc_server_send_remove_id.
2527 Added also silc_server_send_notify_signoff to send the
2528 SIGNOFF notify type.
2530 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2531 SILC protocol from this day on. Changed the protocol
2532 specification as well.
2534 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2535 notify type. It is used between routers to notify about
2536 topic changes on a channel.
2538 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2541 * Partly updated the protocol specification to comply with the
2542 changes now made. It is still though a bit outdated.
2544 * The JOIN notify type now takes one extra argument <Channel ID>.
2545 The packet used to be destined to the channel but now the
2546 JOIN type may be sent as list thus it is impossible to
2547 destine it to any specific channel. By adding this argument
2548 it is again possible.
2550 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Added CREDITS file. The CHANGES and CREDITS file will appear
2553 in the distribution as well.
2555 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2558 types in the server's silcd/packet_receive.c.
2560 * Implemented CMODE and CUMODE to work in router environment.
2562 * Fixed minor encoding and decoding buglet from the
2563 lib/silccore/silcmode.c.
2565 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2568 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2570 * Changed all SilcConfigServer* and silc_config_server* to
2571 SilcServerConfig* and silc_server_config*, respectively.
2574 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Associated the ID (client or server ID) to the Authentication
2577 Payload to avoid any possibility of forging. Updated the
2578 protocol specification and the code accordingly.
2580 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * The RSA key length is now save to the RsaKey context in the
2583 key generation process in lib/silccrypt/rsa.c. The key length
2584 is now used to figure out the maximum size of the block allowed
2585 to be encrypted/signed.
2587 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2588 is equivalent to the silc_mp_mp2bin but does not allocate any
2591 * Changed silc_mp_mp2bin API to take length argument. If it is
2592 non-zero then the buffer is allocated that large. If zero, then
2593 the size is approximated using silc_mp_sizeinbase, which however
2596 * Created Global RNG API which is global RNG that application can
2597 initialize. After initializing, any routine anywhere in the
2598 code (including library) can use RNG without allocating a new
2599 RNG object. This was done to allow this sort of use of the
2600 RNG in code that has no chance to allocate RNG object. All
2601 applications currently allocate this and many routines in the
2602 library use this. Affected file lib/silccrypt/silcrng.[ch].
2604 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2605 it to use the Global RNG API.
2607 * Defined Authentication Payload into protocol specification that
2608 is used during SILC session to authenticate entities. It is
2609 used for example by client to authenticate itself to the server
2610 to obtain server operator privileges.
2612 Implemented this payload into the lib/silccore/silcauth.[ch].
2613 Implemented also routines for public key based authentication
2614 as the new protocol specification dictates.
2616 Moved definitions of different authentication methods from
2617 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2619 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2620 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2621 silc_pkcs_verify_with_hash functions into the file
2622 lib/silccrypt/silcpkcs.[ch].
2624 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * The client entry's userinfo pointer must be always valid.
2627 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2628 will fail since it requires the userinfo. Now, the userinfo
2629 is allocated as "" if actual userinfo does not exist. Actually,
2630 it must exist and it is totally Ok to drop client connections
2631 that does not announce the userinfo. However, we will make
2632 this workaround for now.
2634 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2635 to return the remote port by socket.
2637 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2640 SILC_SERVER_PENDING_EXEC and added an new macro
2641 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2642 data or when error occurs while processing the pending command.
2644 Added new argument `destructor' into silc_server_command_pending
2645 and to the SilcServerCommandPending object. This destructor is
2646 now called after calling the pending callback or if error occurs
2647 immediately. If error occurs the actual pending callback won't
2648 be called at all - only the destructor. The destructor may be
2649 NULL if destructor is not needed.
2651 All this applies for client library code as well. Similar
2652 changes were made there as well for the pending commands.
2654 In the client, the application must now allocate the
2655 SilcClientCommandContext with the silc_client_command_alloc
2658 * Added reference counter to the SilcServerCommandContext. Added
2659 function silc_server_command_alloc and silc_server_command_dup
2662 Same type of functions added to the client library for the same
2665 * Removed the cmd_ident from IDListData away since it is now
2666 global for all connections. It is the command identifier used
2667 in command sending and with pending commands. The affected file
2670 * Added reference counter to the SilcSocketConnection objecet to
2671 indicate the usage count of the object. The object won't be
2672 freed untill the reference counter hits zero. Currently only
2673 server uses this, and client ignores it. The client must be
2674 set to use this too later. The affected files are
2675 lib/silccore/silcsockconn.[ch]. Added also the function
2676 silc_socket_dup to increase the reference counter.
2678 This was mainly added because it is possible that the socket
2679 is removed underneath of pending command or other async
2680 operation. Now it won't be free'd and proper DISCONNECTING
2681 flags, etc. can be set to avoid sending data to connection that
2682 is not valid anymore.
2684 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2685 the connection. After that it sets SILC_SET_DISCONNECTED.
2686 It is, however, possible that the socket data is not still freed.
2687 The silc_server_packet_process now checks that data is not
2688 read or written to connection that is DISCONNECTED. The socket
2689 get's freed when the reference counter hits zero.
2691 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Changed the client operation API: channel_message operation's
2694 `sender' is now the client entry of the sender, not the nickname
2695 and the `channel' is the channel entry, not the channel name.
2697 In the private_message operation the `sender' is now also the
2698 client entry of the sender not the nickname.
2700 Affected file is lib/silcclient/ops.h and all applications
2701 using the client operations.
2703 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * Moved the calling of ops->connect() from connect_to_server_final
2706 into receive_new_id functin since that is the point when the
2707 client is actually allowed to send traffic to network. The
2708 affected file is lib/silcclient/client.c.
2710 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2713 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2714 (if needs broadcasting) instead of broadcasting the packets one
2715 by one which would make a burst in the network traffic.
2717 * Added `broadcast' argument to the functions in silcd/server.[ch]
2718 silc_server_create_new_channel[_with_id] to indicate whether
2719 to send New Channel packet to primary router.
2721 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Added new function into the silcd/server.[ch] files:
2724 silc_server_create_new_channel_with_id to create new channel with
2725 already existing Channel ID.
2727 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2728 lib/silccore/silcpacket.h. This packet is used t send list of
2729 Set Mode payloads inside one packet. Server uses this to set
2730 the modes for the channels and clients on those channels, that it
2731 announced to the router when it connected to it. The protocol
2732 specification has been updated accordingly.
2734 * The silc_server_new_channel did not handle the packet coming
2735 from normal server as it normally does not send that. However,
2736 when it announces its channels it does send it. Implemented
2737 the support for that.
2739 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2740 into the file lib/silccore/id.h.
2742 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Fixed memory leaks in the functions silc_idlist_del_client,
2745 silc_idlist_del_channel and silc_idlist_del_server in the file
2746 silcd/idlist.c. All of those leaked like a sieve.
2748 * Fixed some small memory leaks in the client's function
2749 silc_client_notify_by_server.
2751 * Added functions into silcd/server.c: silc_server_announce_clients,
2752 silc_server_announce_channels and silc_server_announce_server.
2753 These functions are used by normal and router server to announce
2754 to its primary router about clients, channels and servers (when
2755 router) that we own. This is done after we've connected to the
2758 These functions effectively implements the following packet types:
2759 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2760 and SILC_PACKET_NEW_ID_LIST.
2762 * Added new functions into the silcd/packet_receive.[ch]:
2763 silc_server_new_id_list, silc_server_new_channel_list and
2764 silc_server_new_channel_user_list to handle the incoming
2765 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2767 * Added support of changing Channel ID in the function
2768 silc_server_replace_id. If the server that announces a channel
2769 to the router already exists in the router (with same name but
2770 with different Channel ID), router is responsible to send
2771 Replace ID packet to the server and force the server to change
2772 the Channel ID to the one router has.
2774 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2775 client that the Channel ID has been changed by the router. The
2776 normal server sends this to the client. Client must start using
2777 the new Channel ID as the channel's ID.
2779 Implemented handling of this new type into lib/silcclient/client.c
2780 into the function silc_client_notify_by_server.
2782 * Added new function silc_idlist_replace_channel_id into the files
2783 silcd/idlist.[ch] to replace the Channel ID.
2785 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Call silc_server_command_identify_check always when processing
2788 the IDENTIFY command in silcd/command.c
2790 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2793 send keepalive packets. The packet can be sent by clients,
2794 servers and routers.
2796 Added function silc_socket_set_heartbeat into the file
2797 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2798 If not set, the heartbeat is not performed. The actual
2799 heartbeat is implemented in the low level socket connection
2800 library. However, application is responsible of actually
2803 Added silc_server_send_heartbeat to send the actual heartbeat
2804 packet into silcd/packet_send.[ch]. Server now performs
2805 keepalive with all connections.
2807 * Added silc_task_get_first function into lib/silcutil/silctask.c
2808 to return the timeout task with shortest timeout. There was a bug
2809 in task unregistration that caused problems. TODO has been
2810 updated to include that task system must be rewritten.
2812 * The client library will now resolve the client information when
2813 receiving JOIN notify from server for client that we know but
2814 have incomplete information.
2816 * Rewrote parts of silc_server_remove_from_channels and
2817 silc_server_remove_from_one_channel as they did not remove the
2818 channel in some circumstances even though they should've.
2820 * Encryption problem encountered in server:
2822 The LEAVE command used to send the Channel Key packet to the
2823 router immediately after generating it. However, the code
2824 had earlier sent Remove Channel user packet but not immediately,
2825 ie. it was put to queue. The order of packets in the router
2826 was that Channel Key packet was first and Remove Channel User
2827 packet was second, even though they were encrypted in the
2828 reverse order. For this reason, MAC check failed. Now, this
2829 is fixed by not sending the Channel Key packet immediately but
2830 putting it to queue. However, this is more fundamental problem:
2831 packets that are in queue should actually not be encrypted
2832 because packets that are sent immediately gets encrypted
2833 actually with wrong IV (and thus MAC check fails). So, packets
2834 that are in queue should be encrypted when they are sent to
2835 the wire and not when they put to the queue.
2837 However, the problem is that the current system has not been
2838 designed to work that way. Instead, the packet is encrypted
2839 as soon as possible and left to the queue. The queue is then
2840 just purged into wire. There won't be any fixes for this
2841 any time soon. So, the current semantic for packet sending
2844 o If you send packet to remote host and do not force the send
2845 (the packet will be in queue) then all subsequent packets to the
2846 same remote host must also be put to the queue. Only after the
2847 queue has been purged is it safe again to force the packet
2850 o If you send all packets immediately then it safe to send
2851 any of subsequent packets through the queue, however, after
2852 the first packet is put to queue then any subsequent packets
2853 must also be put to the queue.
2855 Follow these rules and everything works fine.
2857 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Added new function silc_server_remove_clients_by_server to
2860 remove all client entries from ID list when the server connection
2861 is lost. In this case it is also important to invalidate all
2862 client entires as they hold the invalid server entry. This
2863 fixes fatal bug when server has lost connection and will reconnect
2866 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Made some sanity checks to silc_server_daemonise like to check
2869 whether the requested user and group actually exists.
2871 * Added sanity check to SKE's silc_ske_responder_finish to check
2872 that the public and private key actually is valid.
2874 * Invalidate the client's nickname when receiving Replace ID
2875 packet and the Client ID is being replaced. This means that the
2876 server will query the nickname if someone needs it (client)
2879 * Sort the ID Cache in client library when the ID Cache data
2880 has changed (needs sorting).
2882 * Do not allow for SILC client to create several connections to
2883 several servers. The client does not support windows right now
2884 and generating multiple connections causes weird behaviour.
2886 Irssi-silc client does support windows and can handle several
2887 connections without problems, see: www.irssi.org and SILC plugin.
2889 * Fixed some places where client was added to the IDList. The
2890 rule of thumb is following (in order to get everything right):
2891 If the client is directly connected local client then the
2892 `connection' argument must be set and `router' argument must be
2893 NULL to silc_idlist_add_client function. If the client is not
2894 directly connected client then the `router' argument must
2895 bet set and the `connection' argument must be NULL to the
2896 silc_idlist_add_client function.
2898 * The funtion silc_server_packet_send_local_channel actually did
2899 not check whether the client was locally connected or not. It
2900 does that now. Fixed a bug related to LEAVE command.
2902 * Fixed Remove Channel User payload parsing bug in server's
2903 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2905 * The server's silc_server_save_channel_key now checks also the
2906 global ID list for the channel as it might not be in the local
2907 list. Fixed a bug related to LEAVE command.
2909 * Is this the end of the [<unknown>] buglet that has been lurking
2910 around for a long time? A little for loop fix in server's
2911 silc_server_command_whois_parse that is used by both IDENTIFY
2912 and WHOIS command. At least, this was a clear bug and a cause
2913 of one type of [<unknown>] buglet.
2915 * WHOIS and IDENTIFY commands call the function
2916 silc_server_command_[whois/identify]_check function even if
2917 we are not router server.
2919 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added --with-gmp configuration option. If set the GMP
2922 is always compiled in the SILC source tree. If not set then
2923 it is checked whether the system has the GMP3 installed. If
2924 it has then the GMP won't be compiled (the system's headers
2925 and library is used), if it doesn't have it then the GMP is
2926 compiled in the SILC source tree.
2928 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Changed RSA private exponent generation to what PKCS #1
2931 suggests. We try to find the smallest possible d by doing
2932 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2933 not security fix but optimization.
2935 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Added new config entry [Identity] to fork the server and run
2938 it as specific user and group. A patch from Bostik.
2940 * Imported Dotconf configuration library into lib/dotconf.
2941 This will be used to create the SILC configuration files later.
2942 It will appear in the distsribution after this commit.
2944 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * A big code auditing weekend happening. Auditing code for
2947 obvious mistakes, bugs and errors. Also, removing any code
2950 Removed files for being obsolete:
2952 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2953 inline in the file lib/silcutil/silcbuffer.h)
2955 o lib/silcutil/silcbufutil.c (the header has inline versions)
2957 Changed code to fix possible error conditions:
2959 o The buffer formatting routines now check that the destination
2960 buffer really has enough space to add the data. This applies for
2961 both buffer formatting and unformatting
2962 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2963 unformatting was changed to accomodate following rules:
2964 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2965 sent to the function while XXX_*STRING will not allocate or copy
2966 the data into the buffer. Instead it sets the pointer from the
2967 buffer into the pointer sent as argument (XXX_*STRING used to
2968 require that the pointer must be allocated already). This change
2969 makes this whole thing a bit more consistent and more optimized
2970 (note that the data returned in the unformatting with XXX_*STRING
2971 must not be freed now). The routines return now -1 on error.
2973 o Tried to find all code that use buffer_format and buffer_unformat
2974 and added return value checking to prevent formatting and
2975 especially unformatting errors and possible subsequent fatal
2978 o Changed ske->x and ske->KEY to mallocated pointers in
2979 lib/silcske/silcske.h. Fixed possible data and memory leak.
2981 o Added return value checking to all *_parse* functions. Fixed
2982 many memory leaks as well.
2984 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2985 so that buffer overflows would not happen. All code now also
2986 checks the return value as it can fail.
2988 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2990 * Added reconnection support to server if the normal server looses
2991 its connection to the router (for example if router is rebooted).
2992 The server performs normal reconnection strategy implemented
2993 to the server. Affected file silcd/server.c.
2995 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Added new packet type SILC_PACKET_SET_MODE that is used to
2998 distribute the information about changed modes (for clients,
2999 channels and clients channel modes) to all routers in the
3000 network. Updated the protocol specification accordingly.
3002 Added functions into silcd/packet_send.c and
3003 silcd/packet_receive.c: silc_server_send_set_mode,
3004 silc_server_set_mode.
3006 Added new files silcmode.[ch] into lib/silccore that implements
3007 the encoding and decoding of Set Mode Payload. Added new type
3008 SilcSetModePayload. Moved the definitions of different modes
3009 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3011 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Oops, a little mistake in server's connection authentication
3014 protocol. The protocol is not ended with FAILURE but with
3015 SUCCESS if the authentication is Ok. :) Affected file is
3018 * Implemented NICK_CHANGE notify handling in server in the file
3019 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3020 the local clients on the channel. After the changing nickname
3021 in router environment snhould work and the [<unknown>] nickname
3022 should appear no more.
3024 The silc_server_replace_id function that receives the Replace ID
3025 payload now sends the NICK_CHANGE notify type also in the file
3026 silcd/packet_receive.c
3028 * Changed WHOIS and IDENTIFY command to support the maximum amount
3029 of arguments defined in protocol specs (3328 arguments). This
3030 fixed a bug that caused problems when there were more than three
3033 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added extra parameter, command identifier, to the
3036 silc_client_send_command so that explicit command identifier
3039 Changed that ID list routines uses specific command identifier
3040 when sending WHOIS/IDENTIFY requests to the server so that they
3041 can be identified when the reply comes back.
3043 Affected files lib/silcclient/command.[ch],
3044 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3046 * Added `sender' argument to silc_server_packet_send_to_channel
3047 to indicaet the sender who originally sent the packet to us
3048 that we are now re-sending. Ignored if NULL. Affected file
3049 silcd/packet_send.[ch].
3051 * Added some server statistics support in silcd/server_internal.h
3052 SilcServerStatistics structure and around the server code. Also
3053 send some nice statistics information when client is connecting
3056 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Fixed channel ID decoding in server's JOIN command reply in
3059 silcd/command_reply.c
3061 * Fixed braodcasting of replace ID payload to not to send it if
3062 we are standalone server in silcd/packet_receive.c.
3064 * Fixed all channel message sending routines to not to send
3065 packets to clients that has router set, since they are routed
3066 separately in the same function earlier. Affects file
3067 silcd/packet_send.c and all channel packet sending functions.
3069 * In USERS reply, res_argv[i] are not allocated, the table
3070 is allocated. Thus changed that free the table, not its
3073 * In server's whois_check and identify_check if the client is
3074 locally connected do not send any WHOIS commands - they are not
3077 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Fixed some minor bugs in client when sending WHOIS command. The
3080 arguments was in wrong order.
3082 * Removed statis function add_to_channel from server in
3083 silcd/command.c that was previously used with the joining but
3086 * Tested USERS command in router environment successfully with two
3087 routers, two servers and two clients.
3089 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Reorganized the USERS command and command reply in client library
3092 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3093 When the command is given by user we register a pending command
3094 callback that will reprocess the command after the reply has been
3095 received from the server. When reprocessing the packet we then
3096 display the information. Thus, the USERS information is displayed
3097 now in the command callback instead of in the command reply
3098 callback. The processing of the command is same as previously
3099 when server has sent the command reply in the JOINing process.
3101 * Added to USERS command in silcd/command_reply.c to join the client,
3102 we didn't use to know about, to the channel after we've created
3103 a client entry for it. Also, for clienet we did know already still
3104 check whether it is on the channel or not and add it if not.
3106 * Removed silc_server_command_join_notify as the function and its
3109 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Changed the client's pending command handling to the same as the
3112 server's pending command handling. It is also now possible to
3113 execute command reply functions from other command reply
3114 function as the function callbacks for commands and command
3115 replies are one and same. The pending commands are not static
3116 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3117 in client connection context. Thus, pending commands are server
3118 connection specific as it is convenient.
3120 Changed the function silc_client_command_pending and
3121 silc_client_command_pending_del and added new function
3122 silc_client_command_pending_check. Removed the
3123 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3126 * Added cmd_ident, current command identifier, to the client
3127 connection context in lib/silcclient/client.h to keep track on
3128 command identifiers used in command sending. Client's command reply
3129 function handling now supports the mandatory command identifiers.
3131 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3132 funtions in client to fully support pending command callbacks.
3134 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3135 as one of the arguments to the application in the command reply
3138 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3139 before first releasing SILC but came back. Now it is removed again
3140 and should come back nomore. The FORWARDED flag was used only
3141 by the JOINing procedure by forwarding the command packet to router.
3142 Now, the JOINing procedure has been changed to more generic (due
3143 to various router environment issues) and FORWARDED is not needed
3144 anymore for anything. The protocol specification is yet to be
3147 Now, removed silc_server_packet_forward from server and the flag
3148 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3150 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Renamed NAMES command to USERS command. The NAMES was named that
3153 due to historical reasons. Now it is renamed. Also, rewrote
3154 parts of the USERS command. The nickname list is not sent anymore
3155 by the server. Only Client ID and mode lists are sent in the USERS
3156 command. Changed this also to the protocol specification.
3158 The client now resolves the names and stuff after it receives
3159 the USERS list from the server when joining to the channel.
3161 * WHOIS and IDENTIFY commands has been changed to support multiple
3162 Client ID's per command. One can now search for multiple users
3163 in the network by sending only one WHOIS or IDENTIFY command.
3164 Changed the code and the protocol specifications.
3166 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3167 uses silc_server_command_whois_parse to parse the request. */
3169 * If normal server, do not parse the WHOIS and IDENTIFY requests
3170 before sending it to the router. Saves some time.
3172 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Fixed JOIN command on client library. Wrong number of arguments
3175 used to crash the client.
3177 * Added silc_server_channel_has_global function to check whether
3178 channel has global users or not.
3180 * Added silc_server_channel_has_local function to check whether channel
3181 has locally connected clients on the channel.
3183 * The silc_server_remove_from_one_channel now checks whether the
3184 channel has global users or not after given client was removed from
3185 the channel. It also checks whether the channel has local clients
3186 on the channel anymore. If it does not have then the channel entry
3187 is removed as it is not needed anymore.
3189 * The silc_server_notify now checks on JOIN notify whether the joining
3190 client is one of locally connected or global. If it is global then
3191 the channel has now global users on the channel and that is marked
3192 to the channel entry. Also, it now saves the global client to
3193 global list who is joining and JOINs it to the channel. This is
3194 for normal server, that is.
3196 Changed silc_server_send_notify_on_channel,
3197 silc_server_packet_relay_to_channel and
3198 silc_server_packet_send_to_channel check if we are normal server
3199 and client has router set (ie. global client) do not send the
3200 message to that client, as it is already routed to our router.
3202 * Implemented LEAVE notify type handling in silc_server_notify
3205 * Tested LEAVE command in router environment successfully. Tested
3206 with two routers, two servers and two clients.
3210 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3212 * Implemented SIGNOFF notify type handling in silc_server_notify
3215 * silc_server_remove_id now removes the client entry from all channels
3216 it has joined and thusly sends SIGNOFF notify type.
3218 * Rewrote the NAMES list generation in server by removing two excess
3219 loops. The lists are created now inside one loop.
3221 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * silc_server_remove_channel_user checks now also global list
3224 for channel and client.
3226 * silc_server_new_channel_user checks now both local and global
3227 list for channel and client. Fixed a bug in client id decoding.
3228 Used to decode wrong buffer.
3230 * silc_server_channel_message checks now both local and global
3231 list for channel entry.
3233 * Tested channel joining (hence JOIN) in router environment
3234 successfully. Tested with two routers, two servers and two
3237 * Tested channel message sending in router environment successfully.
3239 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Added silc_server_save_channel_key into server.[ch] to save the
3242 received channel key in Channel Key payload processing. It is
3243 also used in JOIN command reply handling.
3245 Equivalent function silc_client_save_channel_key added into
3246 client.[ch] into client library.
3248 * Changed JOIN command reply to send information whether the channel
3249 was created or not (is existing already) and the channel key
3250 payload. Changed protocol specs accordingly.
3252 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3253 the request was sent by ID and not by nickname. Crashed on
3256 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3259 now correctly save the received data.
3261 * silc_server_free_sock_user_data now notifies routers in the
3262 network about entities leaving the network.
3264 At the same time implemented functions silc_server_remove_id
3265 and silc_server_send_remove_id to receive and send REMOVE_ID
3266 packets. The packet is used to notify routers in the network
3267 about leaving entities. The ID removed will become invalid in
3270 * Added function silc_idlist_del_server into server. Removes and
3271 free's server entry from ID list.
3273 * silc_server_private_message function now checks, if we are router,
3274 that the destination ID really is valid ID, naturally.
3276 * In router when NEW_ID packet is received (for new client) the
3277 hash of the Client ID is saved in the ID Cache but the
3278 client->nickname is set to NULL, instead of putting the hash
3281 IDENTIFY command now also checks that client->nickname must be
3282 valid. If it is not if will request the data from the server who
3283 owns the client. Added new function
3284 silc_server_command_identify_check.
3286 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3287 to set the command to already allocated Command Payload.
3289 * Tested private message sending in router environment with two
3290 routers, two servers and two clients. Fixed minor bugs and now
3293 * Fixed segfault from client's NAMES command. Used to crash if
3296 * Forwarded packets must not be routed even if it is not destined
3297 to the receiver. Changed server code comply with this.
3299 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Added `require_reverse_mapping' boolean value to ServerParams
3302 structure. If TRUE (not default) the server will require that
3303 the connecting host has fully qualified domain name.
3305 If the reverse mapping is not required and hostname could not be
3306 found the IP address is used as hostname.
3308 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Implemented version string checking to both client and server.
3311 The check is incomplete currently due to the abnormal version
3312 strings used in development version of SILC.
3314 * Changed all command functions in server to use the new
3317 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Changed char *data to unsigned char *data in ID Cache system to
3320 support binary data as ID Cache data. Changed code to support
3321 binary data in lib/silccore/idcache.c.
3323 * Renamed silc_server_packet_relay_command_reply to
3324 silc_server_command_reply as it is normal packet receiving
3325 function. Rewrote the function to accept command replys for
3326 servers and not only for clients.
3328 * Mark remote router always as registered server if we are connecting
3329 to it. Otherwise, commands sent by the router to us are ignored.
3331 * All ID List find routines now returns the ID Cache Entry pointer
3332 as well if requested.
3334 * WHOIS command works now in router environment, tested with two
3335 routers, two servers and two clients.
3337 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3338 in router environment (as it is almost equivalent to WHOIS) but
3339 hasn't been tested thoroughly. Added new functions:
3341 silc_server_command_identify_parse
3342 silc_server_command_identify_send_reply
3343 silc_server_command_identify_from_client
3344 silc_server_command_identify_from_server
3346 * Disabled route cache adding because adding two different ID's with
3347 same IP replaces the old cache entry thus giving wrong route.
3348 The entry->router->connection is always the fastest route anyway
3349 so route cache may not be needed. Of course, new routes maybe
3350 established after receiving the ID when the entry->router->connection
3351 might not be anymore the most optimal.
3353 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Add route cache for received ID for fast routing.
3357 * Added silc_server_packet_route to route received packet on router
3358 that is not destined to us.
3360 * Renamed silc_server_get_route to silc_server_route_get.
3362 * Added id_string and id_string_len fields into SilcServer to
3363 include encoded ServerID for fast comparing without excess
3364 encoding of the ID's.
3366 * Cleaned up WHOIS command on server side. Added following static
3369 silc_server_command_whois_parse
3370 silc_server_command_whois_check
3371 silc_server_command_whois_send_reply
3372 silc_server_command_whois_from_client
3373 silc_server_command_whois_from_server
3375 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3376 arguments in command replies. All command functions should be
3377 updated to use this macro.
3379 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Minor typo fixes on command reply handling on server.
3383 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added silc_server_command_add_to_channel internal routine to add
3386 the client to the channel after router has created the channel and
3387 sent command reply to the server.
3389 * Added generic silc_server_send_command to send any command from
3392 * Use static buffer with ID rendering instead of duplicating data.
3394 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Fixed a channel user mode bug when joining to a channel server gave
3397 everybody channel founder rights, oops.
3399 * We mark ourselves as the router of the incoming server connection
3400 if we are router ourselves. This way we can check in some packet
3401 sending functions whether it is locally connected server. For
3402 incoming router connections we put NULL.
3404 * For router sending packets locally means now always sending the
3405 packet cell wide; to local clients and local servers. For normal
3406 server sending packet locally means sending it to only local
3409 * Fixed the JOIN command to really work in router environment. If the
3410 channel is created it is always created by the router. Router is
3411 also responsible of making the initial joining to the channel,
3412 sending JOIN notify to the sending server and distributing
3413 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3414 does not exist server doesn't do anything else but forward the
3415 command to the router which performs everything.
3417 * Added silc_server_send_channel_key function to send the Channel Key
3420 * Added silc_server_create_channel_key to create new channel key. The
3421 channel key is now re-generated everytime someone joins or leaves
3422 a channel, as protocol dictates. Note: channel->key_len is the
3425 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3428 packet_receive.[ch] to separate packet sending and receiving
3429 routines. The server.[ch] now includes everything else including
3430 actual packet processing (writing and reading data) and other
3433 Renamed silc_server_private_message_send_internal to
3434 silc_server_send_private_message. The routine is still though
3435 used only to relay private messages as server does not send
3436 private messages itself.
3438 Renamed silc_server_new_channel to silc_server_create_new_channel
3439 and added new function sicl_server_new_channel that handles the
3440 incoming New Channel packet. Added also new sending function
3441 silc_server_send_new_channel to send New Channel Payload.
3443 * Added new function silc_server_notify to process incoming notify
3444 packet to the server/router. Server may then relay the notify
3445 to clients if needed.
3447 * Added new function silc_server_new_channel_user to process incoming
3448 New Channel User packet. Router will redistribute the packet and
3449 send JOIN notify to its local clients and locally connected servers
3450 if needed. Normal server will send JOIN notify to its local client
3451 on same channel when received this packet. Added also corresponding
3452 sending function silc_server_send_new_channel_user to sent the
3455 * Added boolean route argument to send_notif_to_channel and
3456 packet_send_to_channel functions to attempt to route the packet
3457 if it is TRUE and send only locally if it is FALSE.
3459 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * silc_server_replace_id now broadcasts the received replace ID
3462 packet if it is not broadcast packet already. The router must
3463 broadcast to inform other routers about changed ID.
3465 * Added backpointer to server's router into SilcServer context in
3466 silcd/server_internal.h.
3468 * Fixed silc_server_packet_broadcast to send correct broadcast
3471 * The channel key is now distributed to the local client as soon
3472 as it is received from the router (in router environment) so that
3473 no other packet may be sent for the channel until client has
3476 * silc_server_remove_channel_user now broadcasts the received
3477 Remove Channel User packet if it is not broadcast packet already.
3478 The router must broadcast to inform other routers about removed
3481 * Added users field into SilcPacketContext that is a reference count
3482 of the context. One can increase the reference count by calling
3483 silc_packet_context_dup which is now changed to just increase the
3484 reference count instead of duplicating the data. The reference
3485 count is decresed by calling silc_packet_context_free that will
3486 free the data after the reference count hits zero.
3488 For now on the packet context and everything allocated into it
3489 (including the raw packet from network) must be freed by calling
3490 the new silc_packet_context_free function. Added also new function
3491 silc_packet_context_alloc that must be used now to allocate the
3492 context. This also means that if a routine is asynchronous from
3493 silc_[client/server]_packet_parse_type the packet context must
3494 be duplicated by calling silc_packet_context_dup. Otherwise it
3495 gets free'd after silc_[client/server]_packet_parse_type returns.
3496 Also, one must remember that if packet is duplicated then its
3497 reference count must be decresed by calling the free function as
3498 many times as it was duplicated.
3500 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3501 from both client and server.
3503 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Made joining to a channel working in router environment.
3507 * Cleaned up JOIN command on server side and create function
3508 silc_server_command_join_channel internal routine to make the
3511 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Changed silc_command_pending list to SilcDList. Also, added
3514 `ident' field to SilcServerCommandPending structure to identify
3515 the reply and to call correct callback.
3517 Added silc_server_command_pending_check function to replace the
3518 corresnponding macro. The silc_command_pending list is not
3521 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3522 to set identifier to previously allocated Command Payload. It
3523 is used to set identifier for command when resending Command
3526 * Added silc_command_payload_encode_payload to encode Command
3527 Payload buffer from SilcCommandPayload structure.
3529 * Added silc_argument_payload_encode_payload to encode Argument
3530 payload buffer from SilcArgumentPayload structure.
3532 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Changed WHOIS command to support router connection on server side.
3535 The whois request is always sent to router unless the server is
3536 standalone server. After server has received the reply from the
3537 router will it send the reply to the client.
3539 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3540 broadcast received broadcast packet. The function is used only
3541 by router. The broadcast packet is always sent to the router's
3544 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3545 render given ID to printable string, for log files for example.
3547 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Made basic router to router connections working. At least they
3550 can now connect to each other but nothing really works the way
3551 they are supposed - yet.
3553 * Added new initiator token to RouterConnection configuration
3554 file in silcd/serverconfig.[ch]. It is used to tell whether we
3555 are the initiator to the remote router or whether we'll expect
3556 the other end to connect.
3558 * Moved registering of listener task to silc_server_init, hence
3559 the server starts listenning as soon as it is run, even if it
3560 does not have connections to other routers. Let's see how well
3563 * Changed default connection retry timeouts for more suitable in
3566 * Removed cipher and such arguments from silc_idlist_add_client
3567 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3568 Added new function silc_idlist_add_data to add the keys and stuff
3571 * Added SilcIDListData structure and added it to SilcClientEntry
3572 and SilcServerEntry as their first field in the structure. This
3573 way we can explicitly cast the ID entries to the SilcIDListData
3574 structure and get common data for the entries. In past, we had
3575 to first check what type of connection it is and then cast it to
3576 correct ID entry type. Now, we can directly cast the opaque
3577 pointer to the SilcIDListData (no matter what ID entry it actually
3578 is) and get the data needed.
3580 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3583 in some circumstances even if threre were timeout tasks, though not
3584 IO tasks, but tasks anyway. Now fixed.
3586 * Defined SilcServerConnection structure to hold connection specific
3587 stuff about directly connected servers and routers. The definition
3588 is currently in silcd/server_internal.h. I thought about having
3589 a bit more important role fro this struct but for now it is used
3590 only when connecting to other server (or router actually).
3592 * Added connecting retry support in server when connecting to
3593 router(s). The retry feature implement exponential backoff
3594 algorithm. Also, added SilcServerParams structure to hold default
3595 parameters for server. For now, it include these retry settings
3596 and are hard coded. After server is moded to be as Silc Server
3597 Library this structure will be more important.
3599 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Changed client librarys channel->clients table to SilcList and
3602 changed code accordingly.
3604 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Changed client's channel table to SilcList and changed code
3607 accordingly. Also changed SilcChannelClientEntry to include back-
3608 pointer to the channel so that client entry can use that structure
3609 as list as well and we have fast cross-reference to the channel.
3610 This change dramatically decreased the complexity of channel
3611 handling with client entry and vice versa (removed one extra
3612 loop when searching for channel entry from many functions).
3614 * Changed server->sim from table to SilcDList and changed code
3617 * NAMES command can now be used from user interface. It will show
3618 the user list on the channel, neatly.
3620 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3621 Code now saves realname of the user if it becomes available.
3623 * Renamed configure.in to configure.in.pre and made ./prepare
3624 script to automatically add correct version string to
3625 configure.in which it creates from configure.in.pre.
3627 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * NAMES command reply now shows users mode with the nickname when
3632 * Moved silc_client_ch[u]mode[_char] functions from
3633 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3634 place sucks, they are utility functions and should be in some
3637 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3639 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3642 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Added TRQ (efficient deque and list library) into lib/trq. This is
3647 a very good list library that is currently used in the SILC. Defined
3648 SilcList API over the library because I didn't like the API very
3649 much. See lib/trq/silclist.h for the API and examples of how to
3650 use the API. Fixed various places in the code to use the new
3651 SilcList API. The SilcList is meant for lists that has a structure
3652 already defined as a list. It is not suitable to add just some
3653 context to the list (in TRQ, the context is the list actually).
3655 So, I defined SilcDList that can be used for the purpose where
3656 predefined list structure does not exit. This can be used as
3657 such list. Now some context just can be added to the SilcDList.
3658 Currently this list is not used in the SILC just yet, though there
3659 are a lot places where this can replace dynamically allocated
3660 tables and I will fix these places, later, to use SilcDList.
3661 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3662 and use TRQ internally).
3664 Also fixed some annoying warning messages that the original TRQ
3665 code generated. Also minor changes to TRQ's Makefile.in.
3667 * Added support for querying by Client ID to both WHOIS and
3668 IDENTIFY commands into server, as required by the protocol.
3670 * Removed method function pointers from SilcBuffer structure. They
3671 weren't used to anything and just increased the context size for
3672 no good reason. This change also made silc_buffer_alloc and
3673 silc_buffer_free functions inline functions.
3675 * Disabled command flooding detection support until it's fixed so
3676 that it accepts commands in but does not execute them more than once
3679 * Added silc_net_localhost(), to return local hostname, into
3680 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3681 that must be initialized before calling silc_client_init.
3683 * Added new function: silc_server_send_notify_on_channels to send
3684 notify messages to all channels client has joined. It is assured
3685 that the message is sent only once per client.
3687 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3688 lib/silcutil/silcutil.[ch] as silc_format function. The new
3689 function is generic and is used by server as well, not only by
3690 the logging routines.
3692 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3693 the provided version string was not acceptable. Added new function:
3694 silc_ske_check_version into lib/silcske/silcske.h. The function
3695 must be implemented by the application (client or server) and it
3696 does not reside in the SKE library. The function checks the version
3697 string remote end sent.
3699 * Added back pointers (to opaque context and to SilcSocketConnection)
3700 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3702 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3703 duplicate packet context structure.
3705 * Changed `notify' client operation to send same arguments as client
3706 receives from server except for ID's. ID's are mapped to correct
3707 ID entry and that is returned. Also, if channel entry is not sent
3708 by server but the notify is for channel the channel entry is sent
3709 to application (otherwise application doesn't know that it is for
3710 channel (library gets it from packet's Destination ID)).
3712 * Added silc_client_remove_from_channels into client library to
3713 remove a client from all channels it has joined to. Used when
3714 received SIGNOFF notify from server. Added also new function
3715 silc_client_replace_from_channels to replace old ID entry with
3716 new ID entry on all channels. Used when received NICK_CHANGE
3719 * Fixed ID Cache list handling in silc_idlist_get_client in
3720 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3721 to get (or query) client by ID.
3723 * Updated TODO list.
3725 * Added connection authentication status message defined by the
3726 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3727 support for these into the code in client and server side.
3729 * Added generic function silc_client_send_command to send any command
3730 with variable argument list. Application should use this function
3731 to send commands if the command functions provided by the library
3732 does not suite for the application's user interface needs.
3734 * Added new `failure' client operation. Application is notified about
3735 received failure packet if client is executing a protocol. In this
3736 case the protocol's execution has failed.
3738 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3739 is required by the protocol.
3741 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3742 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3745 * Added status flag to SilcSKE object to indicate realtime status
3746 of the SKE protocol.
3748 * Application receives now exactly same command reply arguments as
3749 the library receives from server. However, if ID is received the
3750 corresponding ID entry is returned to the application (eg. Client
3751 ID is mapped to correct SilcClientEntry entry and that is returned).
3752 Changed command_reply client operation due to this change.
3754 * Changed all ID's in commands and in command replys as ID Payloads.
3755 Change affected both client and server side codes.
3757 All ID's sent in SILC network (with execption of ID's in SILC
3758 Packet header) are sent in ID Payload to support variable length
3761 * Server now notifies nick changes and notifies all clients on
3762 the channels about the new nickname (about the new Client ID,
3765 * Implemented CMODE command to change channel modes. Supports all
3766 channel modes defined by the protocol specs except ban and invite
3767 lists. (Also, private channel key mode is supported but support for
3768 setting private channel key in client is missing, thus, this mode
3769 has no effect on client side (except that server requires that the
3770 client uses private channel key and normal channel traffic does not
3773 Also, invite mode works per se, but INVITE command does not work
3774 yet correctly, so you can set channel as invite only channel but
3775 inviting clients to the channel does not work (it is yet to be
3776 thought what's the best way to do it).
3778 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3779 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3780 Implemented CUMODE command to change user's mode on the channel.
3781 Supports all modes defined by the protocol specs.
3783 * Added NAMES command reply to return users modes on the channel.
3785 * Removed unnecessary and slow ciphers from lib/silccrypt.
3787 * Set SO_KEEPALIVE option to connection sockets by default.
3789 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3791 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3792 redefined the Notify Payload into protocol specs.
3794 * Added silc_id_payload_parse_id to get ID directly from raw
3797 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3800 accept searching by Client ID as well.
3802 * Added support for LEAVE and SIGNOFF notify types in client library.
3804 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3805 to parse ID Payload from raw data.
3807 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Added flags parameter into silc_ske_assemble_security_properties
3810 function in lib/silcske/silcske.[ch].
3812 * Changed notify client operation to fit better for notify messages
3813 sent by server. The notify payload received from server is now
3814 passed to the application (after parsing it to SilcNotifyPayload).
3815 It is application's responsibility to retrieve the arguments
3816 from the payload and show the message the way it wants. The message
3817 sent by server is implementation specific.
3819 * Changed public keys to comply with the protocol specification.
3820 Old public keys are not supported anymore and are not compatible.
3822 * Removed nickname from Channel Payload as the latest draft removed
3823 it. The client must resolve the nickname from the NAMES command
3824 reply received when it joined the channel.
3826 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3828 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Fixed some errors in protocol specification drafts.
3832 * Created lib/silccore/silcnotify.c to implement Notify Payload
3833 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3834 generic payloads described by protocol specifications. The file
3835 includes implementations for ID Payload and Argument Payload.
3837 * Changed Command Payload implementation to use the new Argument
3838 Payload. Changed command_xxxx_payload to command_payload_xxxx
3839 to comply with SILC coding conventions.
3841 * Added suppport for Argument Payload handling in Notify Payload
3842 implementation as protocol requires it. Added the new support
3843 into server and client lib as well.
3845 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Added support for multiple nicknames on same channel. [n] is
3848 added locally to the nickname if there are more than one same
3849 nicknames on the channel.
3851 * Server now sends all nicknames that matched WHOIS request.
3852 Client also shows the list received from server.
3854 * Added TOPIC command to client side. User can now set and show
3855 current topic on channel.
3857 * Added MOTD command to client and server. Also, server sends the
3858 motd when client connects to the server.
3860 * Changed version strings to comply ISO 8601.
3862 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Fixed protocol error handling in client library. It should now
3865 cope even if the SKE fails for some reason.
3867 * Made new protocol specification drafts for submitting to IETF.
3869 * Implemented TOPIC command to server in silcd/command.c.
3871 * Added two new notify types into lib/silccore/silcnotify.h:
3872 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3873 notify nickname change and topic setting/change on a channel.
3875 * API change of command_reply operation in client library. The
3876 application gets now the status type received from server as well.
3878 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3882 * Cras fixed and optimized the packet handling even further and
3883 it should work now. Minor change to the prototype of function
3884 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3886 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Added new function into lib/silcutil/silcschedule.[ch]:
3889 silc_schedule_with_fd to select() a specified fd. The function
3890 returns after timeout expires or data arrives or goes. The
3891 function is used by packet routines to wait that all data is
3892 received from network.
3894 * Fixed data reading from network in lib/silccore/silcpacket.c.
3895 The code now assures that all data is read from the fd and then
3896 continues packet processing. This was a bug fix since the code
3897 used to drop some data in some circumstances.
3899 * Added new function into lib/silcclient/client.[ch]:
3900 silc_client_start_key_exchange to start key exchange after
3901 connection has been established to server. The code internally
3902 now uses this funtion but its main purpose was to provide it
3903 for applications that perform their own connecting. After
3904 application has created a connection it merely calls this
3905 function to start the key exchange between client and server.
3906 The library takes care of everything else after that.
3908 Updated also lib/silcclient/README to explain the usage of
3911 * Do not send to application information that connection has
3912 been established. Application gets notified it by connect
3915 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Applied cras's patch to add silc_schedule_one function. The
3918 function runs scheduler once and returns.
3920 * Fixed the scheduler after cras messed it up. The timeout
3921 handling works now as it's supposed to work.
3923 * Added into lib/silccore/ silcnotify.h to include notify
3924 message types support. Changed silc_server_send_notify*
3925 functions, in server.[ch], to support those new notify types.
3926 Added the support for the notify types into client library,
3927 as well. Added new notify client operation into ops.h in
3930 * Changed silc_server_packet_send_to_channel to send normal
3931 packets instead of just channel message packets. The function
3932 is now used to send the notify packets to channels. It is not
3933 used to send channel message packets anymore, as server never
3936 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3937 va_arg()s as it seems to require it nowadays. I guess, if SILC
3938 is compiled with older va_arg() the new code should work anyway.
3940 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Splitted core library. Core library (lib/silccore) includes
3943 now only SILC protocol specific core (and common) components.
3944 Created new utility library (lib/silcutil) that includes more
3945 generic purpose stuff. The stuff for util library was taken
3946 from the old core library. This was minor and easy split.
3948 * Created SILC Client Library (lib/silcclient) that includes
3949 implementation of the SILC client without user interface. This
3950 was major move from silc/ directory. The code has been changed
3951 so that it is transparent towards the user interface. The
3952 silc/ directory includes now the same user interface as before
3953 and it uses the new client library. Read lib/silcclient/README.
3954 Basicly, the client library performs everything else related
3955 to SILC except user interface handling. Also, configuration
3956 files are considered to be part of user interface and library
3957 does not handle them.
3959 This change also changed a lot of structures, function naming etc.
3960 Most important change was that SilcClientWindow object was
3961 renamed to SilcClientConnection in the client library. Created
3962 also new file lib/silcclient/ops.h. Also added new files
3963 silc/local_command.[ch] and silc/client_ops.[ch].
3965 All these changes were made to make it easier for user interface
3966 designers to create what ever user interface for the SILC client
3969 It is also expected that the server will be moved to lib
3970 directory as well and SILC Server Library will be created;
3971 sometimes in the future.
3973 * Removed Local commands from lib/silccore/silccommand.h as
3974 they are application specific and new client library does not
3975 handle any of those anymore.
3977 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3978 old client implementation in silc/.
3980 * Added support for callback functions in SILC_LOG_* macros.
3981 Application can now set its own callbacks that will be called
3982 instead of using the default functions that will always print
3983 the debug messages to stderr (or stdout). Also, debugging can
3984 now be disabled by setting silc_debug to FALSE and re-enabled by
3985 setting it to TRUE. Note, that logging will still work even
3986 if debugging is disabled.
3988 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3989 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3990 silc_log_reset_debug_callbacks.
3992 * To enable debugging in silc client one must give now -d
3993 option on command line.
3995 * Changed silc_schedule_init to automatically allocate task queues
3996 if they are not allocated before calling it.
3998 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Added GMP 3.1 into math library.
4002 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4005 a channel in SILC network. The packet is used by servers and
4006 routers to notify other routers that user has left a channel.
4007 This little feature was missing until now. Added the feature
4008 to protocol specification as well.
4010 Added functions: silc_server_send_remove_channel_user and
4011 silc_server_remove_channel_user into server.[ch].
4013 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4014 lib/silccore/silcpacket.h. However, they are not implemented
4017 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4019 * Fixed joining to a channel and sending channel messages
4020 between server and router. The channel message sending should
4021 now work inside a cell.
4023 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Fixed the private message sending between server and router.
4026 The private message sending should now work inside a cell.
4028 * Added silc_server_replace_id into server.[ch] to replace
4029 existing ID in the SILC network.
4031 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4032 and silc_idlist_replace_server_id into idlist.[ch] in server.
4034 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Fixed the server to server connections. Server can again now
4037 connect to router. Router to router connections probably does
4040 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added dynamic protocol registering support. Now protocols can
4043 registered and unregistered on the fly. Patch by cras.
4045 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Added lib/contrib directory to hold routines that some platforms
4048 don't have but are needed by SILC.
4050 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4051 into lin/contrib to provide getopt() and getopt_long() for
4052 those who don't have it.
4054 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Added AWAY command to client. When away message is set and
4057 client receives a private message packet the client automatically
4058 replies to the sender with the away message.
4060 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4061 bug seemed to be the cause of recent problems when compiling
4064 * Added version detection support to SKE protocol specification
4065 and added the new changes to the SKE implementation as well.
4066 There were other minor changes in the SKE protocol as well.
4068 Many changes in lib/silcske/silcske.[ch] and in
4069 lib/silcske/payload.[ch].
4071 * Added ^U functionality, clear input line. Patch from cras.
4073 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Mainly small bugfixes on core library. Fixed some debugging
4076 logging and buffer overflow in silclog.c.
4078 * Updated config.sub and config.guess on the distribution tree.
4080 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Added command lagging support in server. Client may execute
4083 commands now only once in two seconds.
4085 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Optimized packet reception. MAC computation and checking is now
4088 also more optimized. A lot previously duplicated code is now
4089 used as generic by both client and server.
4091 * Fixed key pair generation in clientutil.c
4093 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Added into lib/silccore/silcbufutil.[ch] new function;
4096 silc_buffer_realloc.
4098 * Moved generic packet sending/encryption functions to
4099 lib/silccore/silcpacket.[ch] from client and server. Some
4100 rewriting of the functions.
4102 * Moved all generic packet reception/decryption functions to
4103 lib/silccore/silcpacket.[ch] from client and server. The
4104 packet processing is now much cleaner in both client and server.
4105 These were major changes in both client and server.
4107 * Created many common functions in server to do packet sending.
4108 Previously code were duplicated a lot, this has been removed
4111 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Rewrote major parts of the ID cache system. Don't know
4114 whether it is better now or not but at least the API is more
4117 * Major rewrite on ID cache stuff on client because of the ID
4118 cache API changes. Added idlist.c to client.
4120 * Also major rewrite on ID cache stuff on server as well.
4121 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4122 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4123 in hand, instead they are all put into the ID cache system now.
4124 All server_idlist_* routines uses ID cache now instead of
4125 traversing its own lists (those lists does not exist anymore).
4126 SilcIDList though still exists. Also, SilcXXXEntry's are
4129 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4131 * Finally made the SKE implementation compliant to the protocol
4132 specification. All mp integers are now binary encoded as
4133 opposed being HEX encoded.
4135 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4138 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4139 functions: silc_[encode/decode]_pem. Also added function
4140 silc_encode_pem_file to PEM encode with newlines ('\n') for
4143 * SILC public keys are now encoded either PEM or binary. Same
4144 option is for private keys as well. By default private keys
4145 are binary encoded and public keys PEM encoded. Silly HEX
4146 encoding were removed.
4148 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4149 function to create fingerprints.
4151 * Fixed a bug in SHA1; does not change the original data anymore.
4153 * Partly implemented INFO command on client and server side.
4154 Fixed CLEAR command. Changes to SERVER command; show current
4155 server(s) when giving command without arguments. Added
4156 VERSION command to client.
4158 * Added check to server that unregistered connections cannot
4159 execute commands (unless it is specificly allowed).
4161 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Fixed screen refresh.
4165 * Fixed channel joining bug from client. On some circumstances
4166 client tried to join to a channel it had already joined.
4168 * Added public key verification process into client's protocol.c.
4169 The client now verifies the public key from user and saves
4170 it into ~./silc/serverkeys/ directory.
4172 Added into: clientutil.[ch]: silc_client_verify_server_key.
4174 * Changed SKE protocol's silc_ske_initiator_finish function
4175 to accept callback function that verifies the received public
4176 key. Removed old silc_ske_verify_public_key function.
4178 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4181 silc_pkcs_private_key[_data]_set.
4183 * Made the password and public authentication more cleaner in
4184 server's protocol.c.
4186 * Removed historic and obsolete protocol `channel_auth' from
4187 both client and server.
4189 * Removed wrong way of sending command status messages from
4190 server to client in server's command.c. The old way violated
4191 protocol specification.
4193 Changes to silccore/silccommand.[ch]: removed
4194 silc_command_encode_status_payload -> not needed anymore,
4195 changed silc_command_encode_payload_va to accept extra
4196 argument on variable argument list. The argument type must
4197 now be provided to the function. Also, added new function:
4198 silc_command_encode_reply_payload_va which is same as
4199 normal command_encode_payload_va except command status type
4200 is provided as extra argument.
4202 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Added ~./silc directory handling. The directory includes the
4205 public and private keys for the client.
4207 Added silc_client_check_silc_dir, silc_client_create_identifier
4208 and silc_client_load_keys.
4210 * Implemented SILC protocol compliant public key. Added public
4211 and private key saving to and loading from files.
4213 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4214 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4215 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4216 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4217 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4219 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4220 silc_pkcs_load_[public/private]_key.
4222 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Added silc_server_get_route (route.[ch]) to get connection
4225 data for the fastest route for given ID.
4227 * Implemented INVITE command on client and server. The command
4228 were re-defined in the SILC Protocol Specification and the
4229 implementation now complies with the specification.
4231 * Implemented PING command on client and server.
4233 * Implemented NAMES command on client and server. The server side
4234 supports currently only normal server not router server yet.
4235 Some changes to NAMES definition in SILC protocol specification.
4237 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Implemented LEAVE command on client and server.
4241 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4242 again. This change was made to the protocol as well. Server
4243 should not violate the protocol specification anymore.
4245 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4248 was tested. SOCKS4 was not but should work anyway.
