1 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added preliminary support for native WIN32 compilation under
4 cygwin (using the -mno-cygwin option for GCC) to the
5 ./configure.in.pre. The --with-win32 now prepares the
6 compilation for native WIN32.
8 * Rewrote the SILC Scheduler interface in the file
9 lib/silcutil/silcschedule.h. The scheduler is now context
10 based and does not have anymore any global static scheduler.
11 Moved the Unix scheduler to the lib/silcutil/unix/ directory
12 and created lib/silcutil/win32 directory for WIN32 based
15 * Added Unix specific network routines to the
16 lib/silcutil/unix/silcunixnet.c and the old
17 lib/silcutil/silcnet.c includes now only generic routines.
19 Added WIN32 specific network routines to the
20 lib/silcutil/win32/silcwin32net.c.
22 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
24 * Do not handle JOIN notify in the server if the target client
25 is not registered (idata->registered == FALSE). The affected
26 file is silcd/packet_receive.c.
28 * Update the nickrec->founder in event_cumode in the Irssi SILC
29 client. Affected file irssi/src/silc/core/silc-channels.c.
31 * Fixed the CUMODE_CHANGE notify handling in the server when
32 server and router are announcing their clients on channels.
33 Now the mode changes are saved and notified correctly. The
34 affected file is /silcd/packet_receive.c.
36 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
37 They really did not replace the cache entry in the ID Cache.
38 Now they do that. Affected file silcd/idlist.c.
40 * Fixed the KICK notify handling in the Irssi SILC client to
41 update the channel records so that the kicked client does not
42 appear to be on the channel. The affected file is
43 irssi/src/silc/core/silc-channels.c.
45 * Always update the conn->current_channel when executing command
46 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
48 * Fixed the KILL notify handling in Irssi SILC client to remove
49 the killed client on all channels.
51 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
53 * Fixed the silc_parse_command_line to remove extra spaces
54 from the start and end of the arguments. Affected file is
55 lib/silcutil/silcutil.c.
57 * Cancel and free any active protocol in the function
58 silc_server_close_connection. Affected file silcd/server.c.
60 * Cancel and free any active protocol in the function
61 silc_client_close_connction. Affected file is
62 lib/silcclient/client.c.
64 * Do not execute the KILL command for clients that are in
65 history (ie. they are not in the network). Affected file is
68 * Fixed KILL notify handling, client does not crash anymore.
69 Affected file irssi/src/silc/core/silc-channels.c.
71 * Reduced the default packet buffer size from 2048 to 1024 in
72 lib/silccore/silcpacket.c.
74 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
75 counter to the SKE context that is incresed when the SKE library
76 performs async operation outside the library. If the outside
77 process frees the SKE context and FREED status will be set
78 and the library will detect after the sync operation that the
79 libary is freed. The affected files are
80 lib/silcske/silcske[_status].[ch].
82 * Resolve the client entry information in the function
83 silc_client_channel_message to assure that NULL pointer is not
84 passed as client entry to the application. */
86 * Fixed the task timeout calculation to assure that there is
87 never negative timeouts. The affected file is
88 lib/silcutil/silcschedule.c.
90 * Fixed the channel user mode notification sending in server.
91 It was sent point-to-point to the router (or to server by router)
92 but it needs to be destined to a channel. The routines now
93 supports sending the channel user mode notifys to the channels
94 when announcing clients and channels. Affected files are
95 silcd/server.c and silcd/packet_receive.c.
97 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
98 It did not actually replace the old channel entry in the cache.
99 Affected file lib/silcclient/client_notify.c.
101 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
103 * Fixed a possible crash in silc_packet_send_prepare. It now
104 assures always that there is enough space in the buffer and
105 at the tail area of the buffer (for MAC).
107 Fixed the inbound buffer reallocation in silc_packet_read.
108 It was old code and did not handle the reallocation correctly.
111 The affected file is lib/silccore/silcpacket.c.
113 * Fixed buffer overflow in silc_parse_nickname in the file
114 lib/silcutil/silcutil.c.
116 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * make install generates new server keys only if there is not
121 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
124 Added check that if the NOREPLY is set then we will not send
125 the away message. This avoids infinite loop of away messages
126 if both clients are away. The affected file is
127 lib/silcclient/client_prvmsg.c.
129 * Fixed client crash if /NICK was given without arguments.
130 Affected file lib/silcclient/command.c.
132 * Server does not send the invite list in INVITE command back
133 to the client if the list was not altered. Added this notion
134 to the protocol spec as well. Affected file silcd/command.c.
136 Fixed possible crash in INVITE command by checking the
137 value of silc_server_get_client_route command.
139 * Fixed the INVITE notify type handling. The arguments are now
140 taken in correct order and client does not crash. The affected
141 file is irssi/src/silc/core/silc-channels.c.
143 Removed the "Inviting xxx to channel" message from the
144 client library away and let the application handle it.
145 Affected file lib/silcclient/command.c. Added that message
146 to Irssi SILC client's message formats.
148 * Fixed CMODE command crash in client. It now checks the
149 amount of arguments correctly and does not crash. The affected
150 file is lib/silcclient/command.c.
152 * Do not create new channel automatically in silc_channels_join
153 but check whether the channel by that name already exists.
154 Affected file irssi/silc/core/silc-channels.c.
156 * Do not send the SERVER_SIGNOFF to router if the disconnected
157 entity was the router. Affected file silcd/server.c.
159 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
160 SILC client as it was missing from there.
162 Added the handling of the KICK notify to the Irssi SILC client
163 as it was missing. Added "you have been kicked" message to
164 Irssi SILC client's message modules formats.
166 Added the handing of the KILL notify to the Irssi SILC client
167 as it was missing. Added the kill message module formats
170 The affected file is irssi/src/silc/core/silc-channels.c.
172 * The router did not save the channel mode the server announced.
173 Affected file silcd/packet_receive.c.
175 * Fixed a possible crash in INFO command in server. If the
176 server did not provide the server info it crashed. Affected
177 file silcd/command.c.
179 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
181 * Fixed the GETKEY command in the server to check also the
182 global list. Otherwise the GETKEY would not work correctly
183 in normal SILC server. Affected file silcd/command.c.
185 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Fixed GETKEY crash, it crashed if the command did not succseed.
189 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
192 is now real and not just an macro interface to GMP.
194 Removed the entire GMP from the source tree and imported new
195 NSS MPI library instead. Reason for removing GMP is that it is
196 extremely large and compiles extremely slow. The NSS MPI
197 is only a few files and compiles in less than 10 seconds.
198 The speed is also about the same as GMP. The MPI is imported
201 If the system has GMP installed we will still use the GMP.
202 If it is not then the NSS MPI will be compiled.
204 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Merged a long nickname (127 characters long) crash bugfix from
207 Irssi CVS tree. Affected file irssi/src/core/misc.c.
209 * Merged a freed memory reference bugfix from Irssi CVS tree.
210 Affected file irssi/src/core/commands.c.
212 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Added the server's public key sving and verification to the
215 server when performing the SKE. This was missing and the
216 remote server's (or router's) public key was accepted without
217 checking whether we have it previously or trust it at all.
218 Affected file silcd/protocol.c.
220 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
222 * Check in the silc_server_timeout_remote if protocol is active
223 and make sure that the protocol's final callback is called so
224 that all memory if freed. Affected file silcd/server.c.
226 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
228 * silc_server_whois_send_reply crashed the server if the nickname
229 was 127 characters long. Affected file silcd/command.c.
231 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Added sanity check to the silc_server_new_client. If the hostname
234 is provided inside username then check that the provided hostname
235 really is the same as the resolved one. If the hostname was not
236 resolved then check it from the public key. Affected file is
237 silcd/packet_receive.c.
239 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
240 if the server disconnected us and the connection is not valid
241 anymore. Affected file irssi/src/silc/core/silc-channels.c.
243 * Moved the silc_client_[chmode|chumode|chumode_char] away from
244 the library to the lib/silcutil/silcutil.[ch].
246 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * Close log file after open. Affected file
249 lib/silcutil/silclog.c.
251 * Check whether sock == NULL in silc_client_send_packet and return
252 if it is. Affected file lib/silcclient/silcclient.c.
254 * Check rec->entry == NULL in the Irssi SILC Client before
255 sending the channel message. Affecte file is
256 irssi/src/silc/core/silc-servers.c.
258 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Merged a splitted window bugfix from Irssi CVS tree. The
261 affected file is irssi/src/fe-text/textbuffer-view.c.
263 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
264 It did not print nickname.
266 * Improved the distributions system a bit.
268 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
270 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
271 irssi/src/fe-text/gui-window.c.
273 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
274 to in-active server. The affected file is
275 irssi/src/silc/core/client_ops.c.
277 * Resolve the client in USERS command reply if the entry does
278 not have username resolved. The affected file is
279 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
280 command to WHOIS command to really resolve stuff. The USERS
281 is not used any more in any critical section so WHOIS can
282 be used even though it might be slower than IDENTIFY.
284 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
287 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
289 * Changed the protocol API a bit more consistent in the
290 lib/silccore/silcprotocol.[ch].
292 * Changed the following headers to ROBODoc format:
294 lib/silccore/silcpayload.h
295 lib/silccore/silcprotocol.h
296 lib/silccore/silcsockconn.h
298 All core library headers are now formatted.
300 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
302 * Fixed a bug in Irssi SILC client; do not show that you are
303 server/router operator if you really are not. Affected file is
304 irssi/src/silc/core/client_ops.c.
306 * Renamed silc_command_free_payload to silc_command_payload_free.
307 Affected file lib/silccore/silccommand.h
309 * Added silcmath.h to include the prototoypes of various routines
310 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
313 * Changed the following headers to ROBODoc format:
315 lib/silccore/silcchannel.h
316 lib/silccore/silccommand.h
317 lib/silccore/silcid.h
318 lib/silccore/silcidcache.h
319 lib/silccore/silcmode.h
320 lib/silccore/silcnotify.h
321 lib/silccore/silcpacket.h
322 lib/silcmath/silcmath.h
324 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Added checking to the server code not to start the server if
327 ciphers and stuff are not configured properly. Affected files
328 silcd/serverconfig.[h] and silcd/server.c.
330 * Changed the layout of the header files of the public interfaces
331 in the SILC libraries. The new layout supports ROBODoc
332 documentation tool (and some others) so that it is easy to create
333 a library reference manual. All the other headers and source
334 code must still follow the CodingStyle document. Also source
335 code must not include these ROBODoc stuffs, only the headers.
336 Furthermore, all public interface headers must now be named
337 by using `silc' prefix, example: silcapi.h, silccipher.h.
338 Some files were renamed due to this. All the other headers
339 must not be used as public interfaces. I will update the
340 CodingStyle document later. Changed following headers, so far:
342 lib/silcclient/silcapi.h
343 lib/silccore/silcauth.h
344 lib/silccore/silcprivate.h
345 lib/silccrypt/silcdh.h
347 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Removed silc_client_packet_send_flush from the client library
352 as it is not needed. Affected file lib/silcclient/client.[ch].
354 * Added printing of message of unresolved authentication method
355 to the Irssi SILC client. Added it to the module formats.
356 Removed the same message from the client library.
358 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Added new distribution feature, DISTLABEL. Every distribution
361 can define own preprocessor label that can be used in the
362 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
363 file distributions, acconfig.h.pre and prepare.
365 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Added Makefile.defines_int to include the actual definitions
368 for Makefile.defines.in. Tested the new distribution system,
369 created distributions and tested installation.
371 * Added AWAY message printing to the Irssi SILC client. Added
372 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
374 * Added SCONNECT command to call the SILC's CONNECT command.
375 Cannot use CONNECT directly since Irssi uses that internally.
376 Affected file irssi/src/silc/core/silc-servers.c.
378 Added ACTION local command. It is same as ME command but takes
379 the channel as mandatory argument.
381 Rewrote some of the Irssi's help files to suite for SILC
384 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * Added Makefile.defines[.in] that should for now on be included
387 in all Makefile.am file in the source tree. That file includes
388 all common compilation definitions for SILC source tree.
390 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Minor changes to the ./prepare script to change the package
393 name according the distribution name to the configure.in.
395 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Created new distribution system. Added file `distributions'
398 that defines all the distributions that can be created out of
399 the SILC source tree. The ./prepare script now reads that
400 file to determine how to prepare the distributions. The
401 first argument to the ./prepare is the name of the distribution
402 and second is the version of the distribution. If given
403 without arguments it creates the default (toolkit) distribution
404 with the default version (defined in ./prepare).
406 All Makefile.am files that are subject to the distributions
407 are now named as Makefile.am.pre. These are ./Makefile.am
408 and lib/Makefile.am. Others may be changed later.
410 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Added invite list, ban list, some key management and connection
413 error message printing to module formats in the Irssi SILC client.
415 * Added new silc_client_set_away_message to set the away message
416 that is back to the person who sent private message. The
417 affected file lib/silcclient/silcapi.h and the
418 lib/silcclient/client_prvmsg.c.
420 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
422 * Fixed the private message sending in the Irssi SILC client,
423 added local command KEY to the Irssi SILC client.
425 Added key management and key agreement message formats to the
426 irssi/src/fe-common/silc/module-formats.[ch].
428 Added USERS (alias WHO) printing, server/router operator
429 indication and LIST command printing to the module formats.
431 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Fixed channel joining notify handling, cumode notify handling
434 from Irssi SILC client.
436 * Added SILC specific module-formats to the Irssi SILC client so
437 that SILC specific message hilighting, colors etc is possible.
438 Affected file irssi/src/fe-common/silc/module-formats.[ch].
440 Added channel mode, channel user mode, actions, notices,
441 whois and whowas printing to the the module-formats.c.
443 * Fixed a bug in channel deletion in the server. The channel
444 is not left to the cache even if the channel founder auth mode
445 is set when there are no users anymore on the channel. Affected
448 * The silc_net_localhost now resolves the entire hostname including
449 the domain name. Affected file lib/silcutil/silcnet.c.
451 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Changed the ask_passphrase client operation to be ascynchronous.
454 It has now a completion callback and a context that the
455 application must call after it has got the passphrase from
456 the user. Affected files lib/silcclient/silcapi.h,
457 lib/silcclient/protocol.c, lib/silcclient/command.c and
460 Added SilcAskPassphrase callback that the application calls
461 to deliver the passphrase to the library.
463 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
464 The public key verification and especially a certificate
465 verification is asynchronous procedure.
467 Added new SILC_SKE_STATUS_PENDING status to indicate the
468 request is pending and a callback will be called to finalize
471 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
472 indicate that remote end did not send its public key (or
473 certificate), even though we require it. Added check for this
474 condition in the SKE. This was a security bug, now fixed.
476 Defined new SilcSKEVerifyCbCompletion callback that is called
477 when the verification process is completed.
479 The affected files lib/silcske/silcske_status.h and
480 lib/silcske/silcske.[ch].
482 * Changed the verify_public_key client operation to be async
483 as well. Defined SilcVerifyPublicKey callback that is used to
484 indicate the success of the public key verification process.
486 Changed the server and client to use the new async client
489 * Changed the Irssi SILC client's internal scheduler to be called
490 twice as many times as it used to be. As a result the client
491 should be a bit faster now. Affected file is
492 irssi/src/silc/core/silc-core.c.
494 * Added support to Irssi SILC client of asynchronous public key
495 verification and passphrase inquiry. Affected file is
496 irssi/src/silc/core/silc-core.c.
498 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
500 * Do not say "You have left channel %s" in client library.
501 Moved it to the application. Affected files are
502 lib/silcclient/command.c and silc/client_ops.c.
504 * Fixed silc_client_get_clients. Command context was not
505 duplicated and was freed memory in the callback. Affected
506 file lib/silcclient/idlist.c.
508 * Do not say "you are now talking..." on JOIN command in the
509 client library. The appliation must handle it.
511 * Do not say ".. changed topic to" in command reply in the
512 client libary. The application must handle it.
514 * Fixed TOPIC command sending in the client library.
516 * Fixed a memory leak in silc_client_command_free in the file
517 lib/silcclient/command.c.
519 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Imported a modified version of Irssi client to the source tree.
522 The Irssi will be used to create a new client called
523 Irssi SILC. Imported to irssi/.
525 Added silc_core_init_finish function to the Irssi. Affected
526 file irssi/configure.in.
528 A lot changes in the Makefile.ams around the irssi tree.
530 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Do not rehash if the new size is same as the old size of the
533 hash table, in the silc_hash_table_rehash*. The affected file
534 lib/silcutil/silchashtable.c.
536 * Replaced hash_table_del_by_context calls from the server
537 (when channel->user_list and client->channels) to the
538 hash_table_del as it is sufficient and faster.
540 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Added silc_hash_table_list, silc_hash_table_get and the
543 SilcHashTableList structure to provide an alternative way to
544 traverse the hash table. The affected files are
545 lib/silcutil/silchashtable.[ch].
547 * Changed the server's idlist routines to use the hash table
548 routines to optimize the code.
550 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
552 * Replaced the client entry's `channel' list and channel entry's
553 `user_list' list to hash tables for optimized lookup. Changed
554 the code to use the hash table interface around the code.
555 Affected file lib/silcd/idlist.[ch].
557 * Added `auto_rehash' boolean argument to the function
558 silc_hash_table_alloc to indicate whether the hash table should
559 auto-rehash when it thinks is appropriate time. It will
560 increase the hash table size if the there is twice as much
561 entries in the table than the size of the table, and will
562 decrease the size if there are twice as less entries than
563 the size of the table.
565 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
567 * Fixed silc_xxx_get_supported to not crash at some circumstances.
569 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * silc_idcache_purge_by_context deletes the entry now by context
572 as it is supposed to do. Affected file lib/silccore/idcache.c.
574 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
575 client is not anymore valid (WHOWAS givens the info) and not
576 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
578 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
580 * Removed the `data' and `data_len' arguments from the ID Cache
581 interfaces and added `name' argument. ID Cache does not handle
582 anymore the binary data only a names associated with given ID.
584 * When hashing a Client ID with silc_hash_id the entire ID is
585 not hashed anymore, instead only the hash of the Client ID is
586 hashed. This way we can access the Client ID from the cache
587 with Client ID but with the hash of the ID (which is a hash of
588 the nickname) as well without any difference in performance.
590 Added also silc_idcache_find_by_id_one_ext to do one on one
591 searching when we have the actual ID. Added also function
592 silc_hash_client_id_compare. The affected files are
593 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
595 * When hashing the name associated with a ID it is always done
596 in lowercase. This way we can access the cache without worrying
597 about case-sensitivity, even though, for example nicknames are
600 * Fixed a bug in server with channel message sending. It put
601 wrong ID type as destination ID. The affected file
604 * silc_idcache_del_by_context now deletes from all hash tables
605 by context. Affected file lib/silccore/idcache.c.
607 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Changed the client library to use the new ID Cache interface.
610 Changes around the source tree.
612 * Added silc_hash_table_rehash_ext to rehash with specific
613 hash function. Affected file lib/silcutil/silchashtable.[ch].
615 * Added silc_hash_string_compare to compare two strings in the
616 hash table. Affected file lib/silcutil/silcutil.[ch].
618 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * Added new function silc_idcache_del_by_context into the
621 lib/silccore/idcache.[ch].
623 * Changed the server's ID list routines to use the new ID Cache
624 interface. Changes around the source tree.
626 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Added silc_hash_table_del[_by_context]_ext functions in to the
629 lib/silcutil/silchashtable.[ch].
631 Removed silc_hash_table_find_all* routines and added new
632 silc_hash_table_find_foreach to replace them.
634 Added silc_hash_table_replace_ext function as extended
635 replacing function. Separated the simple hash table interface
636 from the extended hash table interface in the file
637 lib/silcutil/silchashtable.h.
639 * Fixed minor bugs and changed it to use some of the new
640 hash table functions in lib/silccore/idcache.c
642 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Added new function silc_hash_table_find_all to return all keys
645 in the hash table by the specified key. As the hash table is
646 collision resistant it also makes it possible to have several
647 duplicate keys in the hash table. This function may be used to
648 find all of the keys from the hash.
650 Added user_context arguments to the SilcHashFunction,
651 SilcHashCompare and SilcHashDestructor to deliver user specified
654 Added new fuctions silc_hash_table_find[_all]_ext to do
655 extended lookup with specified hash and compare functions and
656 specified user contexts.
658 Added new function silc_hash_table_add_ext to add the key
659 with specified hash function and user context.
661 Added new function silc_hash_table_foreach to traverse all
662 entrys in the hash table. Added SilcHashForeach callback
665 Added new function silc_hash_table_del_by_context to delete
666 the entry only if the context associated with the key matches.
668 Affected files are lib/silcutil/silchashtable.[ch].
670 * Removed silc_hash_[server/client/channel]_id and added just
671 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
672 silc_hash_id_compare to compare two ID's using as the hash table
673 comparison function. Added also silc_hash_data to hash
674 binary data and silc_hash_data_compare to compare it.
676 * Removed silc_idlist_find_client_by_hash as it is not needed
677 anymore. Affected file silcd/idlist.[ch].
679 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
680 to use internally the SilcHashTable. The new ID Cache is a lot
681 faster than the old one. Some of the ID Cache interface was also
682 rewritten and obsolete and stupid functions were removed.
684 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * Added entry_count field to the SilcHashTable to keep the number
687 of the entries in the table. Implemented the function
688 silc_hash_table_rehash. Added new function
689 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
691 Fixed a minor bug in silc_hash_table_free.
693 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
694 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
695 into the lib/silcutil/silcutil.[ch].
697 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Implemented a collision resistant hash table into the
700 lib/silcutil/silchashtable[ch]. See the header and the source
701 for the SilcHashTable API.
703 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
705 * Merged dotconf version 1.0.2 into lib/dotconf.
707 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Do not compile anything in lib/silcsim/* if the SIM support
710 is not enabled. The tree should now compile without problems
713 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * Compiled the SILC under cygwin. Compiled and tested briefly
716 without problems. More tests needed. The SIMs didn't compile
719 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
721 * Fixed possible crash in silc_get_username in the
722 lib/silcutil/silcutil.c.
724 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Fixed a va_arg in silc/client_ops.c.
728 * Oops, RC5 routines were named AES and caused some problems
729 when not using SIM's. Affected file lib/silccrypt/rc5.c.
731 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Added new SilcIDIP structure into the lib/silccore/id.h and
734 replaced the old `ip' fields from all SILC ID's to that type.
735 This is a step towards IPv6 support.
737 The silc_id_get_len takes now the ID as an extra argument.
738 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
739 both IPv4 and IPv6 based ID's.
741 The affected files are lib/silccore/id.[ch] and other files
742 around the tree using these routines.
744 * Removed the ID length arguments in server from various
745 silc_server_send_notify_* routines -> they are not needed
748 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Fixed memory leak in silc_encode_pem_file in the file
751 lib/silcutil/silcutil.c.
753 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Check minor version as well in the SKE. Affected files are
756 silcd/protocol.c and lib/silcclient/protocol.c.
758 * Added --identifier option to the server so that an identifier
759 can be when creating the public key for the server. Affected
760 file is silcd/silcd.c.
762 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
763 lib/silccrypt/silcpkcs.c.
765 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Register default ciphers and stuff when using -C option with
768 the server. Affected file sildc/silcd.c.
770 * Put back the servers public key filename format, it is better
771 than the new one. For now, the client keys are saved with the
772 new filename format. The affected file silc/client_ops.c.
774 * Implemented the Cipher API for the rest of the ciphers that
775 did not implement it or implemented it the wrong way.
777 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Register default ciphers and stuff when using the -S option
780 in the client. Affected file silc/silc.c. Same also when
781 creating new key pair with -C option.
783 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Fixed the silc_verify_public_key client operation function to
786 save the public keys differently. The fingerprint is now
787 used as filename and not the hostname. This way also the
788 client keys are saved uniquely and not with hostnames. The
789 affected file is silc/client_ops.c.
791 * Trimmed the silc_hash_fingerprint function to remove extra
792 whitespaces from the end of the fingerprint. The affected
793 file is lib/silccrypt/silchash.c.
797 * Added silc_cipher_register_default function to register all
798 default ciphers. It can be used when configuration files
799 does not exist and the application does not want any specific
800 ciphers in any specific order.
802 The SilcDList is now used as silc_cipher_list dynamically
803 allocated cipher list. Removed the static list all together
804 and now all ciphers must be allocated to the dynamic list.
805 The silc_cipher_alloc routine was changed to check only the
808 All silc_cipher_* routines that used to return int returns
811 The affected files lib/silccrypt/silccrypt.[ch].
813 * The same thing was done to silc_hash_* as for silc_cipher_*
814 routines. Affected files lib/silccrypt/silchash.[ch].
816 * The same thing was done to silc_pkcs_* as for silc_cipher_*
817 routines. Affected files lib/silccrypt/silcpkcs.[ch].
818 Added also silc_pkcs_[un]register[_default] functions.
819 Removed the data_context from the PKCS API.
821 * Added silc_hmac_register_default function to register default
822 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
823 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
824 to unregister all hmacs at once.
826 * Register the default ciphers, hash functions, PKCSs and HMACs
827 if client's configuration file does not exist. The affected
830 * The client did not load the hash functions from the SIM
831 modules at all. Added support for this. Affected file is
834 * When decoding public key with silc_pkcs_public_key_decode, check
835 the supported algorithm only if PKCS are registered. Affected
836 file lib/silccrypt/silcpkcs.c. The same was done with the
837 silc_pkcs_private_key_decode.
839 * Fixed the SILC List routines to keep the list always in order.
840 It used to change the list's order when traversing the list but
841 not it preserves the order. Affected file lib/trq/silclist.h.
843 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Added the client library to use the SilcSocketConnection's
846 reference counter (by silc_socket_dup) to prevent the bug that
847 the socket object may be freed underneath async operation.
849 * The name resolv library checking fixes in the configure.in.pre.
852 * Created new version of the protocol drafts for future
853 development. The -03 drafts are the ones that will be changed
854 in the trunk now and the -02 will remain as they are.
856 * Send list of CUMODE notifys to the router when announcing
857 the channel users to the router. Affected file silcd/server.c.
858 If the router receiving channel founder CUMODE for a channel
859 that already has channel founder it will send CUMODE notify
860 to the sender to remove the channel founder rights from the
861 announced client. Affected file silcd/packet_receive.c.
863 * The CUMODE notify may now use Server ID as well as the entity
864 who changes the mode. Updated protocool specs.
866 * Updated INSTALL and README files.
868 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * New web pages in the http://silc.pspt.fi. The pages was
875 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Implemented the [DenyConnectin] config section in the server.
878 Added silc_server_config_denied_conn to check whether incoming
879 connection is denied. Affected file silcd/serverconfig.[ch].
881 * Do not check the ports when checking the incoming configuration
882 data if the port is 0, meaning any. Affected file is
883 silcd/serverconfig.c.
885 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Fixed buffer overflow in silc_string_compare in the file
888 lib/silcutil/silcutil.c.
890 * Fixed double free in silc_server_command_leave in the file
893 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Fixed the version checking in the server. Affected file is
898 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Fixed the configuration data fetching when accepting new
901 connections in the server. Affected file silcd/server.c.
903 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Added `sender_entry' argument to the function
906 silc_server_packet_relay_to_channel so that we can check
907 whether some destination actually belongs to the same route
908 the sender belongs (ie, we must not resend the packet to the
909 sender). Affected file silcd/packet_send.[ch].
911 * Added `servername' field to the SilcClientEntry in the server
912 to hold the name of the server where client is from. Affected
913 file is silcd/idlist.h.
915 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Moved the channel message encrypting in the router betwen
918 router connections from silc_server_channel_message to the
919 silc_server_packet_relay_to_channel since we want to check
920 whether we have anybody channel before encrypting anything.
921 Affected files silcd/packet_[receive/send].c.
923 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Fixed the [AdminConnection] server config section to support
926 multiple entries. Affected file silcd/serverconfig.c.
928 * Added support into the server to check the validity of the
929 incoming connection before executing any KE or authentication
932 * The connection configuration is now saved to the KE and
933 connection auth protocol contexts and not fetched anymore in
934 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
936 * The local hosts listenning address and port is also resolved
937 now when starting the server. We want to have the socket object
938 to include the real address and port for the listener. Added
939 new function silc_net_check_local_by_sock into the files
940 lib/silcutil/silcnet.[ch].
942 * Fixed a broadcast bug in server -> do not broadcast if we
945 * Fixed a routing bug. Do not route broadcast packets ever.
946 Broadcast packets must be processed always and not routed since
947 they may be destined to some other host than yourself and thus
948 would get routed without no good reason. Affected file is
951 * Added function silc_server_config_is_primary_route to check
952 whether primary router connection has been configured (a router
953 configuration that we are initiating). If there is not, we
954 will assume that there is only two routers in the SILC network
955 and we will use the incoming router connection as our primary
956 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
958 * Changed the order of the broadcasting. Broadcast _after_ the
959 packet has been processed not before. Affected file is
962 * Fixed a [ClientConnection] parsing bug. The port was never
963 parsed correctly thus resulting to port 0. Affected file
964 silcd/serverconfig.c.
966 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
967 argument and did not set the broadcast packet flag. Affected
968 file silcd/packet_send.c. Fixed same bug in the function
969 silc_server_send_notify as well.
971 * If we receive NEW_ID packet for our own ID in the server, ignore
974 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
978 * Removed the nickname from the Private Message Payload.
979 Updated the code and the protocol specs.
981 * Updated protocol specs for submitting to the IETF.
983 * Tweaked the Random Number Generator a bit. Affected file
984 lib/silccrypt/silcrng.c. Exported a new function
985 silc_rng_[global]_add_noise which can be used to add more
988 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
990 * Do not parse packets with different timeout when protocol
991 is active -> may cause problem with rekey. Affected file
994 * When server receives signoff notify it must not create
995 new channel key if the client is on any channels since the
996 sender of the signoff notify will create it.
998 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1000 * Added printing of error messages during SKE protocol from the
1001 failure packet sent by server during SKE. Affected file
1004 * Removed the client's failure_callback handling with timeout
1005 and handle it immediately when received.
1007 * The SKE library returned wrong type in SUCCESS and FAILURE
1008 packets. They must be 32 bit MSB not 16 bit MSB.
1010 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Ok, rewrote the logic of the re-key and now it seems to work.
1013 I tested it on high traffic with frequent re-keys without
1014 problems. Added hmac_receive (and renamed hmac to hmac_send)
1015 in SilcClientConnection in lib/silcclient/client.h and
1016 in SilcIDListData in silcd/idlist.h. Also, removed the
1017 SilcPacketParserContext's cipher and hmac fields as they are
1018 not needed anymore and actually caused some problems when
1019 the ciphers and hmac's changed underneath the packet parser.
1021 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * If re-key protocol is active then process the incoming packets
1024 synchronously since we must assure that icoming packets encrypted
1025 with the old key is processed before the new keys is set to
1026 use. This is true other packets than for REKEY packets.
1027 Affected file silcd/server.c. The same was done to client library
1028 as well, affected file lib/silcclient/client.c.
1030 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Fixed bug in client and server to accept the force send if
1033 the packet is send from silc_[server/client]_packet_process
1034 function. Otherwise the packets are never delivered, oops.
1036 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Disable force sending of packets when REKEY protocol is active.
1039 We must assure that no packet is sent directly when rekey is
1040 performed. All packets must be sent through packet queue.
1041 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1042 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1043 function is silc_[server/client]_packet_send_real to check
1046 * Replaced the SIM paths from example config files to
1047 /usr/local/modules. Also, make install creates now
1048 /usr/local/silc/logs directory to hold all the SILC server
1051 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Made the configure.in.pre work on Solaris. Patch by salo.
1055 * Made all ciphers compatible with non-x86 machines. Defined
1056 CBC mode macros into lib/silccrypt/ciphers_def.h.
1058 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Fixed the make install.
1062 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1064 * When MAC computation fails the silc_packet_decrypt returned 0
1065 even though it was supposed to return -1. Fixed this. The
1066 affected file is lib/silccore/silcpacket.c.
1068 * Do not replace the config files in /etc/silc (in make install)
1069 if they already exist. Affected file ./Makefile.am.
1071 * Do not send re-key packets immediately but through packet queue.
1072 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1074 * Changed silc_net_check_host_by_sock to return FALSE if the
1075 IP/DNS could not be resolved. Though, it returns the IP address
1076 now even if it could not resolve it (but returns also FALSE).
1077 Affected file lib/silcutil/silcnet.[ch].
1079 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * Added silc_pkcs_decode_identifier to decode the public key's
1082 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1083 Added also silc_pkcs_free_identifier. Added also new context
1084 SilcPublicKeyIdentifier.
1086 * Added -S option to the silc client. It is used to dump the
1087 contents of the specified public key file.
1089 * Changed the PKCS api to return the public key length when
1090 setting the public key.
1092 * Fixed a fatal bug in the public and private key file loading.
1093 Affected file lib/silccrypt/silcpkcs.c.
1095 * Execute the packet parsing for client with zero (0) timeout
1096 if the protocol is active. Affected file silcd/server.c.
1098 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Made the key generation options to the silcd program. Added
1101 -C option, equivalent to client's option.
1103 * Added new [ServerKeys] config section to the server. It
1104 configures the server's public and private key.
1106 * Defined generic Public Key Payload into the protocol
1107 specification to send specific type of public keys and
1110 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1111 public key or certificate.
1113 * Implemented the GETKEY command to the server and to the
1114 client library and on user interface.
1116 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Made preliminary `make install' work.
1120 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1122 * Added SilcServerRekey context into silcd/idlist.h.
1124 * Added the PFS support as defined in the specification to the
1125 SKE protocol. Affected files lib/silcske/*.c.
1127 * Added `ske_group' field to the SilcServerRekey context to hold
1128 the number of the SKE group that is used with PFS in re-key.
1129 Affected file silcd/idlist.h.
1131 * Added PFS re-key support to the server. Affected file is
1134 * Added silc_protocol_cancel to cancel execution of the next
1135 state of the protocol. Affected file is
1136 lib/silccore/silcprotocol.[ch].
1138 * Added the re-key support with and without PFS to the client
1139 library. Re-key is performed once in an hour, by default.
1141 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1142 Added silc_client_rekey_callback and silc_client_rekey_final.
1143 Affected files are lib/silcclient/protocol.[ch] and
1144 lib/silcclient/client.[ch].
1146 * Removed the `hmac_key' and `hmac_key_len' fields from the
1147 SilcClientConnection structure; not needed. Affected file is
1148 lib/silcclient/client.h.
1152 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Do not ask whether user wants to use the negotiated private key
1155 for private messages, just use it. Affected file is
1156 silc/local_command.c.
1158 * Added `send_enc_key' and `enc_key_len' fields to the
1159 SilcIDListData structure since they are needed in the re-key
1160 phase. Affected file is silcd/idlist.[ch].
1162 * Implemented the simple re-key protocol into the server.
1163 Affected files silcd/server.c and silcd/protocol.[ch]. The
1164 re-key will be performed once in an hour, by default.
1166 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1167 Added silc_server_rekey, silc_server_rekey_callback and
1168 silc_server_rekey_final.
1170 * Removed Tunneled flag from the protocol. Updated the code
1171 and the specifications.
1173 * Adde `pfs' field to the SilcIDListData to indicate whether
1174 the PFS is to be performed in the re-key. Affected file is
1177 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1180 int64 of at least the xintXX size. If void * is less that 4
1181 bytes uint32 * will be used. Defined bool as boolean.
1183 * Changed _ALL_ unsigned long and unsigned int to uint32,
1184 unsgined short to uint16 in the source tree.
1186 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1187 not handle clients that has entry->data.registered == FALSE.
1188 They are not in the network anymore. Affected file is
1191 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Implemented the sending of the SERVER_SIGNOFF notify in the
1194 server. Affected file is silcd/server.c.
1196 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1197 Added also silc_notify_payload_encode_args into the
1198 lib/silccore/silcnotify.[ch].
1200 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1201 Affected file silcd/packet_receive.c.
1203 * Implemented the SERVER_SIGNOFF notify handling in the client
1204 library. Affected file lib/silcclient/client_notify.c. Also,
1205 implemnted the printing of the SERVER_SIGNOFF info to the
1206 application. Affected file silc/client_ops.c.
1208 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1209 if the deleting was successful. Affected file silcd/idlist.[ch].
1211 * Added support for public key authentication in the connection
1212 authentication protocol in the client library. Affected file
1213 lib/silcclient/protocol.c.
1215 * Changed the server's silc_idlist_get_clients_by_* interface
1216 to support already allocated array so that new entries may be
1217 added to pre-allocated array. Affected file silcd/idlist.[ch].
1218 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1219 and command replies.
1221 * All command reply functions in the server now calls the
1222 pending command callback even if error occured. This way the
1223 error will be delivered to the client as well. Affected files
1224 silcd/command.c and silcd/command_reply.c.
1226 * Fixed INFO command to return local server's info if no server
1227 was provided. Affected file lib/silcclient/command.c.
1229 * Removed RESTART command for good. Updated the code and the
1232 * Rewrote parts of the task system. It is a bit simpler now.
1233 Removed unsued task priorities. The affected files are
1234 lib/silcutil/silctask.[ch].
1236 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Moved the USERS printing from the library to the application.
1239 Affected files lib/silcclient/command.c and silc/client_ops.c.
1241 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Added channel key re-key support. The re-key is perfomed
1246 only by the router and is done once in an hour. Added `rekey'
1247 field to the SilcChannelEntry in the server. Affected files
1248 silcd/server.c and silcd/idlist.h.
1250 * Added silc_task_unregister_by_context into the file
1251 lib/silcutil/silctask.[ch].
1253 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1255 * Added SILC_UMODE_GONE mode to indicate when the client is not
1256 present in the SILC network. Added also support to the local
1257 command AWAY that will set this mode. Added support of showing
1258 "xxx is gone" in WHOIS command. The USERS command shows the
1259 gone status as well.
1261 * Fixed setting server and router operator privileges in the
1262 server's UMODE command. Affected file silcd/command.c.
1264 * Merged the SKE KE1 and KE2 payloads into one payload. The
1265 new KE payload is equivalent to the old KE2 payload.
1267 Cleaned up the SKE Start Payload parsing. It now uses the
1268 simple buffer unformatting to do the parsing. A lot faster
1271 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1272 to the SKE that is used to indicate whether both of the SKE
1273 parties should perform authentication. By default only the
1274 responder performs authentication. By setting this flag also
1275 the initiator must do authentication. By default it is unset
1276 since in normal SKE case, client to server connection, only
1277 the responder should do authentication. When doing SKE between
1278 two clients both should perform authentication. Updated the
1279 code and the protocol specs.
1281 * A little fix to IDENTIFY command in the server. Search the
1282 client first by hash not nickname. Affected file is
1285 * Fixed the silc_client_close_connection to support closing
1286 the client to client connections wihtout deleting too much
1287 data. Affected file lib/silcclient/client.c.
1289 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1290 are received if protocol used to be active but is not anymore
1291 the application would crash due to NULL pointer dereference.
1292 Affected files silcd/server.c and lib/silcclient/client.c.
1294 * Added `hash' field to the SilcClientConnection to include
1295 the hash function negotiated in the SKE protocol.
1297 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1298 to set the channel founder authentication data. A client can
1299 claim the founder rights later by providing the authentication
1300 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1301 This way the channel founder can regain the channel founder
1302 privileges even it is left the channel. This works only on
1303 local server and the client must be connected to the same
1304 server to be able to regain the founder rights. Updated the
1305 protocol specs accordingly.
1307 Added support to the CMODE command in the client to set the
1308 founder auth data. Read the README to see how to set it.
1310 Added support to the CUMODE command to claim the founder
1311 rights. Read the README to see how to do it.
1313 Added support for the founder authentication to the Channel
1314 Entry in the server. Affected file silcd/idlist.h.
1316 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1317 server's CMODE command. Affected file silcd/command.c.
1319 * Added the following new functions into lib/silccore/silcauth.[ch]:
1320 silc_auth_get_method and silc_auth_get_data.
1322 * The server now saves the remote hosts public key to the
1323 SilcIDListData pointer. Affected file silcd/protocol.c.
1325 * The normal server now does not remove the channel entry from
1326 the cache if the founder authentication data is set. It used
1327 to remove it if the founder was the last one on the channel on
1328 the server and left the channel. The auth data is saved and
1329 if the channel is re-joined later the old entry is used with
1330 the old auth data. Affected files silcd/command_reply.c and
1333 * Removed the `pkcs' field from the SilcIDListData structure
1334 in the server; it is not used. Affected file silcd/idlist.h.
1336 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1338 * Fixed packet processing on slow links. Partial packets were
1339 never re-processed because the incoming data buffer was cleared
1340 by the application. Application must not directly clear the
1341 sock->inbuf, the packet processing routines handle it. Fixed
1342 this in client library and in server.
1344 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Fixed the WHOIS and IDENTIFY send reply function to really
1347 check whether to send list or just one entry. Affected file
1350 * Cleaned up the LEAVE command's channel key distribution. The
1351 affected file silcd/command.c.
1353 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1354 can enforce the channel mode as well. In that case the ID
1355 includes the ID of the server. The code now enforces the
1356 mode change if the router have different mode than the server.
1358 * The notify client operation with CMODE_CHANGE notify can now
1359 return NULL client_entry pointer if the CMODE was not changed
1360 by client. Application must check for this.
1362 * Added <Server ID> argument to INFO command to support server
1363 info fetching by Server ID.
1365 * Added silc_server_announce_get_channel_users to get assembled
1366 packets of channel users of the specified channel. Affected
1367 file silcd/server.[ch].
1369 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1370 was freed underneath the ID Cache.
1372 * Re-announce clients when the server received CHANNEL_CHANGE
1373 notify from the router. Affected file silcd/packet_send.c.
1375 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1378 crashed since it did not handle the fact that there is no cipher
1379 called "3" and didn't check the error condition. Now fixed.
1381 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1382 flag. It can be used to send message requests.
1384 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1386 * Implemented the RESTART command in the client.
1388 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1389 notice type messages. Added notice printing to the user
1392 * The channel keys are not re-generated if the channel's mode
1393 is PRIVKEY, ie private key on the channel exists. Affected
1394 files silcd/server.c and silcd/command.c.
1396 * Fixed a little bug in channel message delivery when channel
1397 private keys are set in the server. Affected file is
1398 silcd/packet_send.c.
1400 * Changed the setting on channel->on_channel = TRUE from the
1401 silc_client_save_channel_key to the JOIN command reply. The
1402 key payload is not received if the private channel key is set.
1403 Affected file lib/silcclient/command_reply.c and the
1404 lib/silcclient/client_channel.c.
1406 * When the CMODE_CHANGE notify is sent and the channel private
1407 key mode is removed the channel key must be re-generated in
1408 other cells as well. Added this support for the router in the
1409 silcd/packet_receive.c.
1411 * Added new local command NOTICE to send notice message on
1412 channel. Affected file silc/local_command.[ch].
1414 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Added new local command ME to the client. It is used to send
1417 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1418 some action. Affected file silc/local_command.[ch].
1420 * Changed channel_message and private_message client operations
1421 to deliver the message flags to the application. Added also
1422 the `flags' arguments to the silc_client_send_channel_message
1423 and silc_client_send_private_message functions. Affected file
1426 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Redefined the Private Message Payload to support private message
1429 keys and to support the new private message flags. Updated
1430 the protocol specs. Flags makes it possible to have for example
1431 CTCP style messages.
1433 * Added new type SilcPrivateMessagePayload and defined an API
1434 for it in the lib/silcclient/silcprivate.[ch].
1436 * Tested private message private keys successfully. Tested the
1437 private message key set, unset and list commands with the new
1440 * Redefined the Channel Message Payload to include the channel
1441 message flags (equal with private message flags) to support
1442 for example CTCP style messages.
1444 * Defined some of the message (for channel and private message)
1445 flags. Updated the protocol specs and added the flags to the
1446 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1448 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Added SilcKeyAgreementStatus type to the key agreement routines
1451 to indicate the current status and error if one occured.
1452 The status types are defined in the lib/silcclient/silcapi.h.
1454 * Added new local command KEY that is used to set and unset private
1455 keys for channels, set and unset private keys for private messages
1456 with remote clients and to send key agreement requests and
1457 negotiate the key agreement protocol with remote client. The
1458 key agreement is supported only to negotiate private message keys,
1459 it currently cannot be used to negotiate private keys for channels,
1460 as it is not convenient for that purpose.
1462 * Fixed a minor pending callback setting bug in the function
1463 silc_client_get_client_by_id_resolve, now the function works.
1464 Affected file lib/silcclient/idlist.c.
1466 * Added function silc_net_get_local_port to get local bound
1467 port by socket. Added to lib/silcutil/silcnet.[ch].
1469 * Added `sockets' and `sockets_count' fields to the SilcClient
1470 object. They hold the sockets of the listenning sockets in
1471 the client. Listenning sockets may be for example the key
1472 agreement server. Affected file lib/silcclient/client.[ch].
1473 Added functions the silc_client_add_socket and the
1474 silc_client_del_socket. They are exported to the application
1477 * Added ~./silc/clientkeys to support other client's public keys.
1479 * Renamed verify_server_key client operation to verify_public_key
1480 and added one argument to indicate the type of the connection
1481 (server, client etc.).
1483 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Added silc_server_connection_auth_request to handle the
1486 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1487 silcd/packet_receive.[ch].
1489 * Added silc_server_send_connection_auth_request into the
1490 silcd/packet_send.c to send the connection auth request packet.
1492 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1495 * Fixed the public key authentication in responder side in the
1496 server. The `auth_data' pointer includes the SilcPublicKey
1497 not the path to the public key. Affected file silcd/protocol.c.
1499 * Implemented the public key authentication in the initiator side
1500 in the server. Affected file silcd/protocol.c.
1502 * Removed the [RedirectClient] config section from the server
1503 configuration. Is not needed and I don't want to implement it.
1505 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1507 * Cleaned up the CMODE command in the server. It now works
1508 correctly and supports all the modes defined in the protocol.
1509 Affected file is silcd/command.c.
1511 * Added `hmac_name' field to the SilcChannelEntry in the server
1512 to hold the default HMAC of the channel. It can be set when
1513 creating the channel (with JOIN command). Affected files
1516 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1517 type to indicate the change of the current cipher and hmac
1518 on the channel. Client can safely ignore the <cipher> argument
1519 (if it chooses to do so) since the CHANNEL_KEY packet will
1520 force the channel key change anyway. The <hmac> argument is
1521 important since the client is responsible of setting the new
1522 HMAC and the hmac key into use.
1524 * Fixed the CMODE command in the client library as well.
1526 * Tested CMODE command in router environment successfully.
1528 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1530 * Show the version of the remote client (or server) when connecting
1531 to the server. It is logged to the log file. Affected file
1532 is silcd/protocol.c.
1534 * Fixed the KILLED notify handling in the client library. The
1535 client must be removed from all channels when receiving the
1538 Also, do not remove the client entry when giving the KILL
1539 command but when the KILLED notify is received.
1541 * Removed silc_idlist_find_client_by_nickname from the server.
1542 Not needed anymore. Affected files silcd/idlist.[ch].
1544 * Implemented the CHANNEL_CHANGE notify type handling to the
1545 server. Affected file silcd/server.c.
1549 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1551 * Added silc_server_send_notify_invite to send the INVITE
1552 notify between routers.
1554 * Implemented the INVITE command correctly to the server.
1556 * Implemented the INVITE notify type handling in the server.
1558 * Implemented the INVITE command to the client library and on the
1561 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Added function silc_server_get_client_resolve to find the
1564 client entry by ID from all ID lists and then resolve it
1565 (using WHOIS) if it cannot be found. Affected file is
1568 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Implemented the BAN command to the client library.
1572 * The JOIN command in the server now checks the invite list
1575 * Changed the silc_command_reply_payload_encode_va and the
1576 silc_command_payload_encode_va to support that if argument is
1577 NULL it ignores and checks the next argument. Affected file
1578 lib/silccore/silccommand.c.
1580 * Added silc_server_send_notify_ban to send the BAN notify
1581 type between routers.
1583 * Chaned the silc_notify_payload_encode to support that if
1584 argument is NULL it ignores and checks the next argument.
1585 Affected file lib/silccore/silcnotify.c.
1587 * Tested ban lists in router environment successfully.
1589 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1591 * Implemented BAN command to the server, in silcd/command.[ch].
1593 * Removed the BAN and INVITE_LIST modes from the CMODE command
1596 * Added function silc_string_match to regex match two strings.
1597 Affected files lib/silcutil/silcutil.[ch].
1599 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Redefined parts of the SilcChannelEntry in the server to support
1602 the new ban and invite lists.
1604 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1606 * Redefined the INVITE command. The same command can be used to
1607 invite individuals to the channel but also to manage the invite
1608 list of the channel (to add to and remove from the invite list).
1609 Updated the protocol specs.
1611 * Added new command SILC_COMMAND_BAN that can be used to manage
1612 the ban list of the channel. Updated the protocol specs.
1614 * Removed the channel modes: the SILC_CMODE_BAN and the
1615 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1616 in the CMODE command. The equivalent features are now available
1617 using INVITE and BAN commands. Updated the protocol specs.
1619 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1620 in the network about change in the current ban list. The notify
1621 type is not used by the client.
1623 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1624 support the invite lists.
1626 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Added new function silc_string_regexify that converts string
1629 including wildcard characters into regex string that can
1630 be used by the GNU regex library. Added into the file
1631 lib/silcutil/silcutil.[ch].
1633 Added silc_string_regex_combine to combine to regex strings
1634 into one so that they can be used as one regex string by
1635 the GNU regex library. Added into the file
1636 lib/silcutil/silcutil.[ch].
1638 Added silc_string_regex_match to match two strings. It returns
1639 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1641 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1643 * Imported GNU regex to the soruce tree into lib/contrib.
1644 Fixed some compiler warning from the regex.c.
1646 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1648 * Fixed MOTD command in the server to work in router environment.
1650 * Fixed the MOTD command in the client library to support
1651 the server argument in the command.
1653 * Added `nickname_len' argument to the silc_idlist_add_client
1654 in the server, as the `nickname' argument may be binary data
1657 * Added silc_idlist_get_channels to return all channels from
1660 * Implemented LIST command to the server. Affected file is
1663 * Implemented the LIST command to the client library and on the
1666 * Added [<user count>] argument to the LIST command reply.
1667 With private channels the user count is not shown.
1669 * Updated TODO and README.
1671 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * The client entry's data.registered must be TRUE even with
1674 global client entry on global client list. The data.registered
1675 is used to check whether the client is anymore in the network,
1676 for example with WHOWAS command so it must be valid.
1678 * Fixed the WHOWAS command in the server. It now actually works
1679 in router environment. Added function into silcd/command_reply.c
1680 silc_server_command_reply_whowas_save.
1682 * Added silc_idlist_purge function to the silcd/idlist.c
1683 to periodically purge the ID Cache.
1685 * Fixed INFO command in the server. It works now in router
1686 environment. Added <server name> argument to the INFO command
1687 reply. Updated the protocol specs.
1689 * Fixed minor bug in silc_idcache_purge to not purge if the
1690 expire value is zero.
1692 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1693 they were buggy because of the WHOWAS information.
1695 * Fixed local command MSG to handle the async resolving of
1696 the remote client properly. It used to fail the first MSG.
1697 Affected file silc/local_command.c.
1699 * Added `data_len' field to SilcIDCache context.
1701 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * Update TODO. Todo in commands in the server.
1705 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1708 used by routers as broadcast packet to inform other routers
1709 about the changed user mode.
1711 Implemented the notify handling in the server. Affected file is
1712 silcd/packet_receive.c. Added the function
1713 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1715 * Added new generic Channel Payload and deprecated the New Channel
1716 Payload. The New Channel Payload is now the generic Channel
1719 * Added new argument `mode' to the silc_server_send_new_channel
1720 as it is required in the Channel Payload now.
1722 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1723 and created a new and real SilChannelPayload to represent the
1724 new generic Channel Payload. Implemented the encode/decode
1725 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1727 * Added silc_server_get_client_channel_list to return the list
1728 of channels the client has joined for WHOIS command reply.
1729 Affected file silcd/server.[ch].
1731 * Implemented the channel list sending in the WHOIS command reply
1732 in server and in the client.
1734 Implemented the channel list displaying on the user interface
1735 as well. Affected file silc/client_ops.c.
1737 * Added silc_channel_payload_parse_list to parse list of Channel
1738 Payloads. It returns SilcDList list of SilcChannelPayloads.
1739 Client for example can use this function to parse the list of
1740 channels it receives in the WHOIS command reply. The caller
1741 must free the list by calling silc_channel_payload_list_free.
1742 Affected files lib/silccore/silcchannel.[ch].
1744 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1746 * Added one new argument <user mode> to the WHOIS command reply
1747 to return the mode of the user in SILC. Updated the protocol
1750 Implemented it to the server and client.
1752 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Fixed the mode printing on the user interface on joining.
1755 Affected file silc/client_ops.c.
1757 * Implemented the UMODE command and user modes in general to the
1758 client library and to the user interface.
1760 * Implemented the UMODE command to the server.
1762 * The server now sends UNKNOWN_COMMAND error status if client sends
1763 unknown command. Affected file silcd/command.c.
1765 * All server commands now handle the command identifier the right
1766 way when sending the command reply to the client. The client can
1767 use to identify the command replies with the identifier.
1769 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Added silc_server_get_client_route to resolve the route to
1772 the client indicated by the client ID. Affected file is
1775 * Added silc_server_relay_packet as general function to relay
1776 packet to arbitrary destination. This deprecates functions
1777 like _send_private_message_key, _relay_notify etc. Affected
1778 file is silcd/packet_send.[ch].
1780 Removed silc_server_send_key_agreement,
1781 silc_server_send_private_message_key and
1782 silc_server_packet_relay_notify functions from the file
1783 silcd/packet_send.[ch].
1787 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1788 server. Affected file silcd/packet_receive.[ch].
1790 * Implemented the KILL command to the client. Implemented the
1791 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1792 Affected files lib/silcclient/command[_reply].c and
1793 lib/silcclient/client_notify.c. Implemented the KILL notify
1794 printing in the user inteface.
1796 * Fixed a lot silc_parse_nick memory leaks from the client
1797 library in the file lib/silcclient/command.c.
1799 * Changed the silc_server_send_notify_on_channels's `sender'
1800 argument from SilcSocketConnection to SilcClientEntry to
1801 check the sender as entry and not as connection object and not
1802 to send to the client provided as argument. The affected file
1803 is silcd/packet_send.[ch].
1805 * The notify packets that are destined directly to the client used
1806 to not to be processed by the server. Now changed that and the
1807 server processes all notify packets. After relaying the packet
1808 to the client the notify packet is processed in the server.
1810 * The silc_server_free_client_data now checks whether there is
1811 pending outgoing traffic for the client and purges the data to
1812 the network before removing the client entry.
1814 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1816 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1817 an client is killed from the SILC Network. Updated the protocol
1820 Added new function silc_server_send_notify_killed to the
1821 silcd/packet_send.[ch].
1823 * Added function silc_server_packet_relay_notify to relay notify
1824 packets that are destined directly to a client. In this case
1825 the server does not process the notify packets but merely relays
1826 it to the client. Affected file silcd/packet_send.[ch].
1828 Added also silc_server_packet_process_relay_notify to check
1829 whereto relay the notify. Affected file is
1830 silcd/packet_receive.[ch].
1832 * Implemented the KILL command to the server.
1836 * Added the backup schema desgined last fall to the protocol
1837 specs for everyone to see. The specification is in the
1838 *-spec-xx.txt draft and the packet type definitions for the
1839 backup routers is in *-pp-xx.txt draft. Thusly, added also
1840 new packet type SILC_PACKET_CELL_ROUTERS.
1842 * A big security problem in the implementation discovered. The
1843 signoff of an client did not cause new channel key generation
1844 which it of course should've done. The channel keys must be
1845 always re-generated when client leaves (or signoffs) the channel.
1846 The silc_server_remove_from_channels funtion now handles
1847 the channel key re-generation.
1849 * Added `sender' argument to the silc_server_send_notify_on_channels
1850 to not to send the client provided as argument. Affected file
1851 silcd/packet_send.[ch].
1853 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Implemented OPER and SILCOPER commands into the server and
1858 * Added silc_auth_verify and silc_auth_verify_data to verify
1859 the authentication directly from the authentication payload.
1860 It supports verifying both passphrase and public key based
1861 authentication. Affected file lib/silccore/silcauth.[ch].
1863 * Added `hash' field to the SilcIDListData structure. It is the
1864 hash negotiated in the SKE protocol. Affected file is
1867 * Slight redesigning of the SilcAuthPayload handling routines.
1868 Do not send SilcPKCS but SilcPublicKey as argument.
1870 * Implemented the public key authentication support to the
1871 serverconfig. The public key is loaded from the provided path
1872 and saved as authentication data to void * pointer. Thus,
1873 changed the unsigned char *auth_data to void *auth_data;
1875 * Fixed SHUTDOWN command to send the reply before the server
1876 is shutdown. :) Affected file silcd/command.c.
1878 * Fixed fatal bug in CONNECT command. The hostname was invalid
1879 memory and server crashed. Affected file silcd/command.c.
1881 * Fixed fatal bug in CLOSE command. The server_entry became
1882 invalid but was referenced later in the command. Affected file
1885 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Fixed fatal bug in failure packet handling. Server ignored
1888 the failure and thus crashed when it came.
1892 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1894 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1895 that the command may be executed only once in (about) 2 seconds.
1896 The old SILC_CF_LAG flag is same but allows command bursts up
1897 to five before limiting.
1899 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1900 server code. Various commands now includes the CF_LAG_STRICT
1901 flag to disallow any kind of miss-use of the command.
1903 * Fixed the silc_buffer_unformat to not to allocate any data
1904 if the length of the data is zero. It used to allocate the
1905 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1907 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * Changed the format of AdminConnection configuration section
1910 in the server. Added username of the admin to the format.
1911 Affected files silcd/serverconfig.[ch].
1913 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1914 to return admin configuration data by host, username and/or
1917 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Implemented WHOWAS command to the server. Added the functions:
1921 silc_server_command_whowas_parse,
1922 silc_server_command_whowas_send_reply,
1923 silc_server_command_whowas_from_client and
1924 silc_server_command_whowas_from_server
1926 * Added <Client ID> argument to the WHOWAS command reply. Updated
1927 the protocol specs accordingly.
1929 * Implemented WHOWAS command and command_reply to the client
1932 Implemented the WHOWAS printing on the user interface.
1934 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Added new argument to the WHOWAS command reply, the real name.
1937 It is an optional argument. Updated the protocol specs.
1939 * Added SilcIDCacheDestructor callback that is registered when
1940 the SilcIDCache is allocated. The callback is called when
1941 an cache entry in the ID Cache expires, or is purged from the
1942 cache. Added into lib/silccore/idcache.[ch].
1944 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1945 to destruct the client entries when the cache entry expires.
1946 Other ID Cache's in server and in the client library ignores
1949 * If the ID Cache entry's `expire' field is zero then the entry
1950 never expires. Added boolean `expire' argument to the
1951 silc_idcache_add function in the lib/silccore/idcache.[ch].
1952 If it is TRUE the default expiry value is used.
1954 * Added silc_server_free_client_data_timeout that is registered
1955 when client disconnects. By default for 5 minutes we preserve
1956 the client entry for history - for WHOWAS command.
1958 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Added support to the server to enforce that commands are not
1961 executed more than once in 2 seconds. If server receives
1962 commands from client more frequently, timeout is registered
1963 to process the commands. Affected file silcd/command.c.
1964 Added new function silc_server_command_process_timeout.
1966 * Changed NICK_NOTIFY handling in client library to check that
1967 if the client's nickname was changed, so there is no need to
1968 resolve anything from the server.
1970 * Removed error printing from the WHOIS and IDENTIFY commands.
1971 If error occurs then it is ignored silently in the client library.
1972 The application, however, may map the received error to
1973 human readable error string. The application currently maps
1974 the NO_SUCH_NICKNAME error to string.
1976 * Made the command status message public to the application. Moved
1977 them from lib/silcclient/command_reply.c to
1978 lib/silcclient/command_reply.h. The application can map the
1979 received command status to the string with the
1980 silc_client_command_status_message function.
1982 * Added check to the server to check that client's ID is same
1983 as the Source ID in the packet the client sent. They must
1986 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Added dist-bzip hook to the Makefile.am to make bzip2
1989 compressed distributions.
1991 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Server now enforces the maximum length for the nickname and
1994 the channel as protocol specification dictates. 128 bytes for
1995 nickname and 256 bytes for channel name.
1997 * Moved the WHOIS printing to the application. The client libary
1998 does not print out the WHOIS information anymore, the application
1999 must do it. Renamed silc_client_command_reply_whois_print to
2000 the silc_client_command_reply_whois_save.
2002 The client's idle time is also sent to the application now, and
2003 the idle is shown on screen.
2005 * Added silc_client_command_reply_identify_save to save the
2006 received IDENTIFY entries.
2008 * Do not check for channel private keys in message sending and
2009 reception if the channel does not have the PRIVKEY mode set.
2010 Affected file lib/silclient/client_channel.c.
2012 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2015 just surfaced after chaning the JOIN procedure.
2017 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Added silc_client_get_clients_by_list to get client entries
2020 from Client ID list, that is returned for example by JOIN
2021 and USERS command replies. The application should use this
2022 function for example when JOIN command reply is received to
2023 resolve the clients already on the channel (library does not
2024 do that anymore as USERS command reply is not used in the JOIN
2025 procedure anymore). Affected files lib/silcclient/silcapi.h and
2026 lib/silcclient/idlist.c.
2028 * JOIN command reply and USERS command reply returns now SilcBuffer
2029 pointers instead of unsigned char pointers when returning
2030 the client list and mode list.
2032 * Added <Client ID> argument to the JOIN command reply, mainly
2033 for the server to identify for which client the command was
2034 originally sent. Updated protocol specs accordingly.
2036 * Added SilcDlist private_key pointer to the SilcChannelEntry
2037 in the client to support the channel private keys. Affected
2038 file is lib/silcclient/idlist.h.
2040 * Added SilcChannelPrivateKey argument to the function
2041 silc_client_send_channel_message so that application can choose
2042 to use specific private ke if it wants to. If it is not provided,
2043 the normal channel key is used, unless private keys are set.
2044 In this case the first (key that was added first) is used
2045 as the encryption key.
2047 * Implemented the support for channel private key handling.
2048 Implemented the following functions:
2050 silc_client_add_channel_private_key,
2051 silc_client_del_channel_private_keys,
2052 silc_client_del_channel_private_key,
2053 silc_client_list_channel_private_keys and
2054 silc_client_free_channel_private_keys
2056 Affected file lib/silcclient/client_channel.c.
2058 * Added the support for the private keys in the channel message
2059 sending and encryption and in the message reception and
2060 decryption. Affected funtions are
2061 silc_client_send_channel_message and silc_client_channel_message.
2063 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2065 * Added SKE's key verify callback to the client library's
2066 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2068 * Removed the statement that server (or router) must send USERS
2069 command reply when joining to the channel so that the client
2070 knows who are on the channel. Instead, the client list and
2071 client's mode list is now sent in the JOIN command reply to the
2072 client who joined channel. This is better solution.
2074 * Added function silc_server_get_users_on_channel and function
2075 silc_server_save_users_on_channel to the silcd/server.[ch].
2077 * Removed function silc_server_command_send_users from the
2080 * Do not show topic on the client library anymore. The topic is
2081 sent in the command reply notify to the application and the
2082 application must show the topic now.
2084 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added client searching by nickname hash into the IDENTIFY and
2087 WHOIS commands in the server as they were clearly missing from
2088 them. Affected file is silcd/command.c.
2090 * Fixed a bug in private message receiving in the client library.
2091 The remote ID was freed and it wasn't supposed, now it is
2094 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Minor fix to the channel payload; allocate the data area, as it
2097 needs to be of specific length.
2099 * If the key agreement port is zero then the operating
2100 system will define the bound port. Affected files are
2101 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2103 * Added new function silc_channel_payload_decrypt into the file
2104 lib/silccore/silcchannel.[ch].
2106 * Moved the channel message etc, check from silc_packet_decrypt
2107 to applications. The library calls now a generic
2108 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2109 when the packet is either normal or special. This was done to
2110 allow more wide range of checking that was not allowed when
2111 the code was in library. Now applications can do virtually any
2112 checks to the packet and return to the library the decision how
2113 the packet should be processed. Affected files are
2114 lib/silccore/silcpacket.[ch].
2116 Added silc_server_packet_decrypt_check to the server and
2117 silc_client_packet_decrypt_check to the client library.
2119 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2120 to send with specified source and destination information.
2122 * Channel message delivery between routers was broken after the
2123 channel key distribution was fixed earlier. The channel key
2124 was used be to distributed to other routers as well which is not
2125 allowed by the protocol. Now this is fixed and channel keys
2126 really are cell specific and the channel message delivery between
2127 routers comply with the protocol specification.
2129 * Fixed various commands in server to check also the global list
2130 for the channel entry and not just the local list. The affected
2131 file silcd/command.c.
2133 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Added assert()s to buffer formatting and unformatting routines
2136 to assert (if --enable-debug) when error occurs. Affected
2137 file: lib/silcutil/silcbuffmt.c.
2139 * Changed to auto-reconnect to check whether the remote host is
2140 router and register the re-connect timeout if it is. It used
2141 to check that whether we are normal server, but router must do
2142 auto-reconnect with another router as well. Affected file
2145 * Removed the [<key len>] option from CMODE command as the cipher
2146 name decides the key length, nowadays. See the defined ciphers
2147 from the protocol specification.
2149 * Added [<hmac>] option to the CMODE command to define the HMAC
2150 for the channel. Added SILC_CMODE_HMAC channel mode.
2152 * Added [<hmac>] option for the JOIN command so that user can
2153 select which HMAC is used to compute the MACs of the channel
2156 * Added Hmac field to the Channel Message Payload. The integrity
2157 of plaintext channel messages are now protected by computing
2158 MAC of the message and attaching the MAC to the payload. The
2159 MAC is encrypted. Now, it is clear that this causes some
2160 overhead to the size of the packet but rationale for this is that
2161 now the receiver can verify whether the channel message decrypted
2162 correctly and also when private keys are set for the channel the
2163 receiver can decrypt the packet with several keys and check from
2164 the MAC which key decrypted the message correctly.
2166 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2167 lib/silccrypt/silccipher.[ch].
2169 * Added silc_hash_len to return the digest length into the
2170 lib/silcrypt/silchash.[ch].
2172 * Rewrote parts of Silc Channel Payload interface in the
2173 lib/silccore/silcchannel.[ch]. The encode function now also
2174 encrypts the packet and parse function decrypts it.
2176 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Fixed a minor formatting bug in the SKE's key material processing.
2179 It actually might have processed the keys wrong way resulting
2182 * Redefined the mandatory HMAC algorithms and added new algorithms.
2183 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2184 and hmac-md5 truncated to 96 bits. The mandatory is now
2185 hmac-sha1-96. Rest are optional (including the one that used
2186 to be mandatory). Rationale for this is that the truncated HMAC
2187 length is sufficient from security point of view and can actually
2188 make the attack against the HMAC harder. Also, the truncated
2189 HMAC causes less overhead to the packets. See the RFC2104 for
2192 * Added new [hmac] configuration section. The SKE used to use
2193 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2194 is of course wrong. The official names that must be proposed in
2195 the SKE are the ones defined in the protocol specification
2196 (hmac-sha1-96 for example). The user can configure any hmac
2197 using any hash function configured in the [hash] section. At
2198 least, the mandatory must be configured.
2200 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2202 * Added HMAC list to the SKE proposal list. It has now both
2203 hash algorithm list and HMAC list. This makes the protocol
2204 incompatible with previous versions. The SKE now seems to work
2205 the way it is supposed to work, for the first time actually.
2207 * Defined plain Hash algorithms to the protocol specification.
2210 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2212 * Implemented support for key agreement packets into the server.
2213 Added functions silc_server_key_agreement and
2214 silc_server_send_key_agreement. Other than these functions,
2215 server has nothing to do with this packet.
2217 * Added support for private message key packets into the server.
2218 Added functions silc_server_private_message_key and
2219 silc_server_send_private_message_key.
2223 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2224 called in the protocol's final callback instead in the END
2225 protocol state. This makes a little more sense and in the same
2226 time in client we can use the same protocol routines for normal
2227 key exchange and to key agreement packet handling as well.
2229 * Added to both client's and server's KE protocol context the
2230 SilcSKEKeyMaterial pointer to save the key material. We will
2231 bring the key material to the protocol's final callback by doing
2232 this. The final callback must free the key material.
2234 * Added SKE's packet_send callback into client's KE protocol
2235 context so that the caller can choose what packet sending function
2236 is used. This way we can use different packet sending when
2237 doing normal SKE when doing key agreement packet handling (in
2238 the key agreement packet handling we do not want to encrypt
2241 * Implemented the responder side of the key agreement routines
2242 in the client. The client can now bind to specified port and
2243 accept incoming key negotiation. The key material is passed
2244 to the application after the protocol is over.
2246 * Implemented the processing of incoming Key Agreement packet
2247 in the client. Added function silc_client_key_agreement to
2250 * Implemented the intiator side of the key agreement routines
2251 in the client. The client can now initiate key agreement with
2252 another remote client. The key material is passed to the
2253 application after the protocol is over.
2255 * Created client_keyagr.c to include all the key agreement
2258 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2259 SILC_TASK_CALLBACK except that it is not static.
2261 * Created client_notify.c and moved the Notify packet handling
2262 from the client.[ch] into that file.
2264 * Created client_prvmsg.c and moved all private message and
2265 private message key routines from the client.[ch] into that file.
2267 * Create client_channel.c and moved all channel message and
2268 channel private key routines from the client.[ch] into that file.
2270 * Changed silc_client_get_client_by_id_resolve to resolve with
2271 WHOIS command instead of IDENTIFY command, in the file
2272 lib/silclient/idlist.c.
2274 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Implemented the SKE's responder side to the Client library.
2278 * When FAILURE is received to the protocol do not trust it
2279 blindly. Register a timeout to wait whether the remote closes
2280 the connection as it should do it, only after that process the
2281 actual failure. This was changed to both client and server.
2283 * Added client_internal.h to include some of the structures
2284 there instead of client.h in lib/silcclient/.
2286 * Added function silc_task_unregister_by_callback to unregister
2287 timeouts by the callback function.
2289 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Some "Incomplete WHOIS info" errors has been appearing on the
2292 log files. Took away the entry->userinfo check from WHOIS
2293 reply sending. The entry->userinfo is now " " if client did not
2294 provide one. I thought this was fixed earlier but something
2295 is wrong still. Let's see if the error still appears.
2297 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Fixed a minor bug in the login when the channel key is
2300 re-generated in the server. It used to generate the key in
2301 wrong order and thus caused problems in the channel traffic.
2303 * Fixed a minor bug in channel key distsribution after
2304 KICK command. The key was not sent to the router even though
2307 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Added silc_ske_process_key_material_data as generic routine
2310 to process any key material as the SILC protocol dictates. The
2311 function is used by the actual SKE library but can be used by
2312 applications as well. This relates to the private message keys
2313 and the channel private keys since they must be processed the
2314 same way the normal SILC session keys. The protocol dictates
2315 this. Affected files: lib/silcske/silcske.[ch].
2317 Added also silc_ske_free_key_material to free the
2318 SilcSKEKeyMaterial structure.
2320 * Defined silc_cipher_set_key function to set the key for
2321 cipher without using the object's method function. The affected
2322 files: lib/silccrypt/silccipher.[ch].
2324 * Implemented silc silc_client_add_private_message_key,
2325 silc_client_add_private_message_key_ske,
2326 silc_client_del_private_message_key,
2327 silc_client_list_private_message_keys and
2328 silc_client_free_private_message_keys functions in the
2331 Added functions silc_client_send_private_message_key to send
2332 the Private Message Key payload and silc_client_private_message_key
2333 to handle incoming Private Message Key payload.
2335 * Added Cipher field to the Private Message Key payload to set
2336 the cipher to be used. If ignored, the default cipher defined
2337 in the SILC protocol (aes-256-cbc) is used.
2339 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Removed lib/silcclient/ops.h file.
2343 Redefined parts of the SILC Client Library API. Created new
2344 file silcapi.h that deprecates the ops.h file and defines the
2345 published Client Library API. Defined also private message key
2346 API and channel private key API into the file.
2348 This is the file that the application must include from the
2349 SILC Client Library. Other files need not be included by
2350 the application anymore.
2352 * Added new key_agreement client operation callback and also
2353 defined the Key Agreement library API for the application.
2355 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2357 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2358 is used by clients to request key negotiation between another
2359 client in the SILC network. If the negotiation is started it
2360 is performed using the SKE protocol. The result of the
2361 negotiation, the secret key material, can be used for example
2362 as private message key.
2364 Implemented the Key Agreement payload into the files
2365 lib/silccore/silauth.[ch].
2367 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Redefined ciphers for the SILC protocol. Added some new ciphers
2370 and defined the key lengths for the algorithms. Changed the
2371 code accordingly. The default key length is now 256 bits.
2373 * Fixed SKE key distribution function silc_ske_process_key_material
2374 when the key length is more than 128 bits. The default key
2375 length in SILC is now 256 bits.
2377 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2378 to indicate unsupported algorithm.
2380 * Renamed rijndael.c to aes.c and all functions as well.
2382 * Fixed a long standing channel key setting bug in client library.
2383 Weird that it has never surfaced before.
2385 * Fixed bug in channel deletion. If the entire channel is removed
2386 then it must also delete the references of the channel entry
2387 from the client's channel list as the client's channel entry and
2388 the channel's client entry share same memory.
2390 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Implemented CONNECT and SHUTDOWN commands in the client.
2394 * Implemented CLOSE command to the client.
2396 * Added the function silc_idlist_find_server_by_name into the
2397 files silcd/idlist.[ch].
2399 Added the function silc_idlist_find_server_by_conn into the
2400 files silcd/idlist.[ch].
2402 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * DIE command was renamed to SHUTDOWN. Updated the both code
2407 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2408 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2410 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2413 * Added function silc_server_create_connection function to create
2414 connection to remote router. My server implementation actually
2415 does not allow router to connect to normal server (it expects
2416 that normal server always initiates the connection to the router)
2417 so the CONNECT command is only good for connecting to another
2420 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2423 or some other client was kicked from the channel.
2425 Implemented the handling of the notify type to both client
2428 Implemented silc_server_send_notify_kicked to send the KICKED
2429 notify. It is used to send it to the server's primary router.
2431 * Implemented the KICK command into server and client.
2433 * Added `query' argument to the silc_idlist_get_client function
2434 to indicate whether to query the client from server or not if
2437 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2438 to indicate that the client is not channel founder.
2442 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Removed the rng context from SilcPacketContext structure and
2445 changed that the packet routine uses the Global RNG API.
2447 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Added support for quit message that client can "leave" on the
2450 channel when it quits the SILC. It is ditributed inside the
2451 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2453 Added silc_server_free_client_data that will take the
2454 signoff message as argument.
2456 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2458 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Updated parts of the protocol specification to keep it up
2463 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2466 payloads in one packet.
2468 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2469 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2470 use now the new List flag.
2472 * Also deprecated the following packet types: REPLACE_ID,
2473 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2475 * Added list support for Notify packet in server.
2477 * Added silc_server_send_notify_channel_change to send the
2478 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2479 the silc_server_send_replace_id.
2481 * Added silc_server_send_notify_nick_change to send the
2482 NICK_CHANGE notify type. Deprecates the function
2483 silc_server_send_replace_id.
2485 * Added silc_server_send_notify_join to send the JOIN notify type.
2486 Deprecates the function silc_server_send_new_channel_user.
2488 * Added silc_server_send_notify_leave to send LEAVE notify type.
2489 Deprecates the function silc_server_send_remove_channel_user.
2491 * Added silc_server_send_notify_cmode and
2492 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2493 types. Deprecates the silc_server_send_set_mode function.
2495 * Added SERVER_SIGNOFF notify type to indicate that server has
2496 quit. This means that all clients on the channel from that
2497 server will drop. This can be also used when netsplit happens.
2499 Deprecated REMOVE_ID packet type since it is not needed anymore
2502 Added silc_server_send_notify_server_signoff to send the
2503 SERVER_SIGNOFF notify type. Deprecates the function
2504 silc_server_send_remove_id.
2506 Added also silc_server_send_notify_signoff to send the
2507 SIGNOFF notify type.
2509 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2510 SILC protocol from this day on. Changed the protocol
2511 specification as well.
2513 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2514 notify type. It is used between routers to notify about
2515 topic changes on a channel.
2517 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2520 * Partly updated the protocol specification to comply with the
2521 changes now made. It is still though a bit outdated.
2523 * The JOIN notify type now takes one extra argument <Channel ID>.
2524 The packet used to be destined to the channel but now the
2525 JOIN type may be sent as list thus it is impossible to
2526 destine it to any specific channel. By adding this argument
2527 it is again possible.
2529 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Added CREDITS file. The CHANGES and CREDITS file will appear
2532 in the distribution as well.
2534 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2537 types in the server's silcd/packet_receive.c.
2539 * Implemented CMODE and CUMODE to work in router environment.
2541 * Fixed minor encoding and decoding buglet from the
2542 lib/silccore/silcmode.c.
2544 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2547 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2549 * Changed all SilcConfigServer* and silc_config_server* to
2550 SilcServerConfig* and silc_server_config*, respectively.
2553 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2555 * Associated the ID (client or server ID) to the Authentication
2556 Payload to avoid any possibility of forging. Updated the
2557 protocol specification and the code accordingly.
2559 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * The RSA key length is now save to the RsaKey context in the
2562 key generation process in lib/silccrypt/rsa.c. The key length
2563 is now used to figure out the maximum size of the block allowed
2564 to be encrypted/signed.
2566 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2567 is equivalent to the silc_mp_mp2bin but does not allocate any
2570 * Changed silc_mp_mp2bin API to take length argument. If it is
2571 non-zero then the buffer is allocated that large. If zero, then
2572 the size is approximated using silc_mp_sizeinbase, which however
2575 * Created Global RNG API which is global RNG that application can
2576 initialize. After initializing, any routine anywhere in the
2577 code (including library) can use RNG without allocating a new
2578 RNG object. This was done to allow this sort of use of the
2579 RNG in code that has no chance to allocate RNG object. All
2580 applications currently allocate this and many routines in the
2581 library use this. Affected file lib/silccrypt/silcrng.[ch].
2583 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2584 it to use the Global RNG API.
2586 * Defined Authentication Payload into protocol specification that
2587 is used during SILC session to authenticate entities. It is
2588 used for example by client to authenticate itself to the server
2589 to obtain server operator privileges.
2591 Implemented this payload into the lib/silccore/silcauth.[ch].
2592 Implemented also routines for public key based authentication
2593 as the new protocol specification dictates.
2595 Moved definitions of different authentication methods from
2596 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2598 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2599 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2600 silc_pkcs_verify_with_hash functions into the file
2601 lib/silccrypt/silcpkcs.[ch].
2603 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * The client entry's userinfo pointer must be always valid.
2606 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2607 will fail since it requires the userinfo. Now, the userinfo
2608 is allocated as "" if actual userinfo does not exist. Actually,
2609 it must exist and it is totally Ok to drop client connections
2610 that does not announce the userinfo. However, we will make
2611 this workaround for now.
2613 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2614 to return the remote port by socket.
2616 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2619 SILC_SERVER_PENDING_EXEC and added an new macro
2620 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2621 data or when error occurs while processing the pending command.
2623 Added new argument `destructor' into silc_server_command_pending
2624 and to the SilcServerCommandPending object. This destructor is
2625 now called after calling the pending callback or if error occurs
2626 immediately. If error occurs the actual pending callback won't
2627 be called at all - only the destructor. The destructor may be
2628 NULL if destructor is not needed.
2630 All this applies for client library code as well. Similar
2631 changes were made there as well for the pending commands.
2633 In the client, the application must now allocate the
2634 SilcClientCommandContext with the silc_client_command_alloc
2637 * Added reference counter to the SilcServerCommandContext. Added
2638 function silc_server_command_alloc and silc_server_command_dup
2641 Same type of functions added to the client library for the same
2644 * Removed the cmd_ident from IDListData away since it is now
2645 global for all connections. It is the command identifier used
2646 in command sending and with pending commands. The affected file
2649 * Added reference counter to the SilcSocketConnection objecet to
2650 indicate the usage count of the object. The object won't be
2651 freed untill the reference counter hits zero. Currently only
2652 server uses this, and client ignores it. The client must be
2653 set to use this too later. The affected files are
2654 lib/silccore/silcsockconn.[ch]. Added also the function
2655 silc_socket_dup to increase the reference counter.
2657 This was mainly added because it is possible that the socket
2658 is removed underneath of pending command or other async
2659 operation. Now it won't be free'd and proper DISCONNECTING
2660 flags, etc. can be set to avoid sending data to connection that
2661 is not valid anymore.
2663 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2664 the connection. After that it sets SILC_SET_DISCONNECTED.
2665 It is, however, possible that the socket data is not still freed.
2666 The silc_server_packet_process now checks that data is not
2667 read or written to connection that is DISCONNECTED. The socket
2668 get's freed when the reference counter hits zero.
2670 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Changed the client operation API: channel_message operation's
2673 `sender' is now the client entry of the sender, not the nickname
2674 and the `channel' is the channel entry, not the channel name.
2676 In the private_message operation the `sender' is now also the
2677 client entry of the sender not the nickname.
2679 Affected file is lib/silcclient/ops.h and all applications
2680 using the client operations.
2682 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * Moved the calling of ops->connect() from connect_to_server_final
2685 into receive_new_id functin since that is the point when the
2686 client is actually allowed to send traffic to network. The
2687 affected file is lib/silcclient/client.c.
2689 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2692 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2693 (if needs broadcasting) instead of broadcasting the packets one
2694 by one which would make a burst in the network traffic.
2696 * Added `broadcast' argument to the functions in silcd/server.[ch]
2697 silc_server_create_new_channel[_with_id] to indicate whether
2698 to send New Channel packet to primary router.
2700 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added new function into the silcd/server.[ch] files:
2703 silc_server_create_new_channel_with_id to create new channel with
2704 already existing Channel ID.
2706 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2707 lib/silccore/silcpacket.h. This packet is used t send list of
2708 Set Mode payloads inside one packet. Server uses this to set
2709 the modes for the channels and clients on those channels, that it
2710 announced to the router when it connected to it. The protocol
2711 specification has been updated accordingly.
2713 * The silc_server_new_channel did not handle the packet coming
2714 from normal server as it normally does not send that. However,
2715 when it announces its channels it does send it. Implemented
2716 the support for that.
2718 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2719 into the file lib/silccore/id.h.
2721 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Fixed memory leaks in the functions silc_idlist_del_client,
2724 silc_idlist_del_channel and silc_idlist_del_server in the file
2725 silcd/idlist.c. All of those leaked like a sieve.
2727 * Fixed some small memory leaks in the client's function
2728 silc_client_notify_by_server.
2730 * Added functions into silcd/server.c: silc_server_announce_clients,
2731 silc_server_announce_channels and silc_server_announce_server.
2732 These functions are used by normal and router server to announce
2733 to its primary router about clients, channels and servers (when
2734 router) that we own. This is done after we've connected to the
2737 These functions effectively implements the following packet types:
2738 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2739 and SILC_PACKET_NEW_ID_LIST.
2741 * Added new functions into the silcd/packet_receive.[ch]:
2742 silc_server_new_id_list, silc_server_new_channel_list and
2743 silc_server_new_channel_user_list to handle the incoming
2744 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2746 * Added support of changing Channel ID in the function
2747 silc_server_replace_id. If the server that announces a channel
2748 to the router already exists in the router (with same name but
2749 with different Channel ID), router is responsible to send
2750 Replace ID packet to the server and force the server to change
2751 the Channel ID to the one router has.
2753 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2754 client that the Channel ID has been changed by the router. The
2755 normal server sends this to the client. Client must start using
2756 the new Channel ID as the channel's ID.
2758 Implemented handling of this new type into lib/silcclient/client.c
2759 into the function silc_client_notify_by_server.
2761 * Added new function silc_idlist_replace_channel_id into the files
2762 silcd/idlist.[ch] to replace the Channel ID.
2764 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Call silc_server_command_identify_check always when processing
2767 the IDENTIFY command in silcd/command.c
2769 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2772 send keepalive packets. The packet can be sent by clients,
2773 servers and routers.
2775 Added function silc_socket_set_heartbeat into the file
2776 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2777 If not set, the heartbeat is not performed. The actual
2778 heartbeat is implemented in the low level socket connection
2779 library. However, application is responsible of actually
2782 Added silc_server_send_heartbeat to send the actual heartbeat
2783 packet into silcd/packet_send.[ch]. Server now performs
2784 keepalive with all connections.
2786 * Added silc_task_get_first function into lib/silcutil/silctask.c
2787 to return the timeout task with shortest timeout. There was a bug
2788 in task unregistration that caused problems. TODO has been
2789 updated to include that task system must be rewritten.
2791 * The client library will now resolve the client information when
2792 receiving JOIN notify from server for client that we know but
2793 have incomplete information.
2795 * Rewrote parts of silc_server_remove_from_channels and
2796 silc_server_remove_from_one_channel as they did not remove the
2797 channel in some circumstances even though they should've.
2799 * Encryption problem encountered in server:
2801 The LEAVE command used to send the Channel Key packet to the
2802 router immediately after generating it. However, the code
2803 had earlier sent Remove Channel user packet but not immediately,
2804 ie. it was put to queue. The order of packets in the router
2805 was that Channel Key packet was first and Remove Channel User
2806 packet was second, even though they were encrypted in the
2807 reverse order. For this reason, MAC check failed. Now, this
2808 is fixed by not sending the Channel Key packet immediately but
2809 putting it to queue. However, this is more fundamental problem:
2810 packets that are in queue should actually not be encrypted
2811 because packets that are sent immediately gets encrypted
2812 actually with wrong IV (and thus MAC check fails). So, packets
2813 that are in queue should be encrypted when they are sent to
2814 the wire and not when they put to the queue.
2816 However, the problem is that the current system has not been
2817 designed to work that way. Instead, the packet is encrypted
2818 as soon as possible and left to the queue. The queue is then
2819 just purged into wire. There won't be any fixes for this
2820 any time soon. So, the current semantic for packet sending
2823 o If you send packet to remote host and do not force the send
2824 (the packet will be in queue) then all subsequent packets to the
2825 same remote host must also be put to the queue. Only after the
2826 queue has been purged is it safe again to force the packet
2829 o If you send all packets immediately then it safe to send
2830 any of subsequent packets through the queue, however, after
2831 the first packet is put to queue then any subsequent packets
2832 must also be put to the queue.
2834 Follow these rules and everything works fine.
2836 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Added new function silc_server_remove_clients_by_server to
2839 remove all client entries from ID list when the server connection
2840 is lost. In this case it is also important to invalidate all
2841 client entires as they hold the invalid server entry. This
2842 fixes fatal bug when server has lost connection and will reconnect
2845 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Made some sanity checks to silc_server_daemonise like to check
2848 whether the requested user and group actually exists.
2850 * Added sanity check to SKE's silc_ske_responder_finish to check
2851 that the public and private key actually is valid.
2853 * Invalidate the client's nickname when receiving Replace ID
2854 packet and the Client ID is being replaced. This means that the
2855 server will query the nickname if someone needs it (client)
2858 * Sort the ID Cache in client library when the ID Cache data
2859 has changed (needs sorting).
2861 * Do not allow for SILC client to create several connections to
2862 several servers. The client does not support windows right now
2863 and generating multiple connections causes weird behaviour.
2865 Irssi-silc client does support windows and can handle several
2866 connections without problems, see: www.irssi.org and SILC plugin.
2868 * Fixed some places where client was added to the IDList. The
2869 rule of thumb is following (in order to get everything right):
2870 If the client is directly connected local client then the
2871 `connection' argument must be set and `router' argument must be
2872 NULL to silc_idlist_add_client function. If the client is not
2873 directly connected client then the `router' argument must
2874 bet set and the `connection' argument must be NULL to the
2875 silc_idlist_add_client function.
2877 * The funtion silc_server_packet_send_local_channel actually did
2878 not check whether the client was locally connected or not. It
2879 does that now. Fixed a bug related to LEAVE command.
2881 * Fixed Remove Channel User payload parsing bug in server's
2882 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2884 * The server's silc_server_save_channel_key now checks also the
2885 global ID list for the channel as it might not be in the local
2886 list. Fixed a bug related to LEAVE command.
2888 * Is this the end of the [<unknown>] buglet that has been lurking
2889 around for a long time? A little for loop fix in server's
2890 silc_server_command_whois_parse that is used by both IDENTIFY
2891 and WHOIS command. At least, this was a clear bug and a cause
2892 of one type of [<unknown>] buglet.
2894 * WHOIS and IDENTIFY commands call the function
2895 silc_server_command_[whois/identify]_check function even if
2896 we are not router server.
2898 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Added --with-gmp configuration option. If set the GMP
2901 is always compiled in the SILC source tree. If not set then
2902 it is checked whether the system has the GMP3 installed. If
2903 it has then the GMP won't be compiled (the system's headers
2904 and library is used), if it doesn't have it then the GMP is
2905 compiled in the SILC source tree.
2907 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Changed RSA private exponent generation to what PKCS #1
2910 suggests. We try to find the smallest possible d by doing
2911 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2912 not security fix but optimization.
2914 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Added new config entry [Identity] to fork the server and run
2917 it as specific user and group. A patch from Bostik.
2919 * Imported Dotconf configuration library into lib/dotconf.
2920 This will be used to create the SILC configuration files later.
2921 It will appear in the distsribution after this commit.
2923 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * A big code auditing weekend happening. Auditing code for
2926 obvious mistakes, bugs and errors. Also, removing any code
2929 Removed files for being obsolete:
2931 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2932 inline in the file lib/silcutil/silcbuffer.h)
2934 o lib/silcutil/silcbufutil.c (the header has inline versions)
2936 Changed code to fix possible error conditions:
2938 o The buffer formatting routines now check that the destination
2939 buffer really has enough space to add the data. This applies for
2940 both buffer formatting and unformatting
2941 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2942 unformatting was changed to accomodate following rules:
2943 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2944 sent to the function while XXX_*STRING will not allocate or copy
2945 the data into the buffer. Instead it sets the pointer from the
2946 buffer into the pointer sent as argument (XXX_*STRING used to
2947 require that the pointer must be allocated already). This change
2948 makes this whole thing a bit more consistent and more optimized
2949 (note that the data returned in the unformatting with XXX_*STRING
2950 must not be freed now). The routines return now -1 on error.
2952 o Tried to find all code that use buffer_format and buffer_unformat
2953 and added return value checking to prevent formatting and
2954 especially unformatting errors and possible subsequent fatal
2957 o Changed ske->x and ske->KEY to mallocated pointers in
2958 lib/silcske/silcske.h. Fixed possible data and memory leak.
2960 o Added return value checking to all *_parse* functions. Fixed
2961 many memory leaks as well.
2963 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2964 so that buffer overflows would not happen. All code now also
2965 checks the return value as it can fail.
2967 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added reconnection support to server if the normal server looses
2970 its connection to the router (for example if router is rebooted).
2971 The server performs normal reconnection strategy implemented
2972 to the server. Affected file silcd/server.c.
2974 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Added new packet type SILC_PACKET_SET_MODE that is used to
2977 distribute the information about changed modes (for clients,
2978 channels and clients channel modes) to all routers in the
2979 network. Updated the protocol specification accordingly.
2981 Added functions into silcd/packet_send.c and
2982 silcd/packet_receive.c: silc_server_send_set_mode,
2983 silc_server_set_mode.
2985 Added new files silcmode.[ch] into lib/silccore that implements
2986 the encoding and decoding of Set Mode Payload. Added new type
2987 SilcSetModePayload. Moved the definitions of different modes
2988 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2990 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Oops, a little mistake in server's connection authentication
2993 protocol. The protocol is not ended with FAILURE but with
2994 SUCCESS if the authentication is Ok. :) Affected file is
2997 * Implemented NICK_CHANGE notify handling in server in the file
2998 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2999 the local clients on the channel. After the changing nickname
3000 in router environment snhould work and the [<unknown>] nickname
3001 should appear no more.
3003 The silc_server_replace_id function that receives the Replace ID
3004 payload now sends the NICK_CHANGE notify type also in the file
3005 silcd/packet_receive.c
3007 * Changed WHOIS and IDENTIFY command to support the maximum amount
3008 of arguments defined in protocol specs (3328 arguments). This
3009 fixed a bug that caused problems when there were more than three
3012 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added extra parameter, command identifier, to the
3015 silc_client_send_command so that explicit command identifier
3018 Changed that ID list routines uses specific command identifier
3019 when sending WHOIS/IDENTIFY requests to the server so that they
3020 can be identified when the reply comes back.
3022 Affected files lib/silcclient/command.[ch],
3023 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3025 * Added `sender' argument to silc_server_packet_send_to_channel
3026 to indicaet the sender who originally sent the packet to us
3027 that we are now re-sending. Ignored if NULL. Affected file
3028 silcd/packet_send.[ch].
3030 * Added some server statistics support in silcd/server_internal.h
3031 SilcServerStatistics structure and around the server code. Also
3032 send some nice statistics information when client is connecting
3035 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Fixed channel ID decoding in server's JOIN command reply in
3038 silcd/command_reply.c
3040 * Fixed braodcasting of replace ID payload to not to send it if
3041 we are standalone server in silcd/packet_receive.c.
3043 * Fixed all channel message sending routines to not to send
3044 packets to clients that has router set, since they are routed
3045 separately in the same function earlier. Affects file
3046 silcd/packet_send.c and all channel packet sending functions.
3048 * In USERS reply, res_argv[i] are not allocated, the table
3049 is allocated. Thus changed that free the table, not its
3052 * In server's whois_check and identify_check if the client is
3053 locally connected do not send any WHOIS commands - they are not
3056 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Fixed some minor bugs in client when sending WHOIS command. The
3059 arguments was in wrong order.
3061 * Removed statis function add_to_channel from server in
3062 silcd/command.c that was previously used with the joining but
3065 * Tested USERS command in router environment successfully with two
3066 routers, two servers and two clients.
3068 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Reorganized the USERS command and command reply in client library
3071 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3072 When the command is given by user we register a pending command
3073 callback that will reprocess the command after the reply has been
3074 received from the server. When reprocessing the packet we then
3075 display the information. Thus, the USERS information is displayed
3076 now in the command callback instead of in the command reply
3077 callback. The processing of the command is same as previously
3078 when server has sent the command reply in the JOINing process.
3080 * Added to USERS command in silcd/command_reply.c to join the client,
3081 we didn't use to know about, to the channel after we've created
3082 a client entry for it. Also, for clienet we did know already still
3083 check whether it is on the channel or not and add it if not.
3085 * Removed silc_server_command_join_notify as the function and its
3088 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * Changed the client's pending command handling to the same as the
3091 server's pending command handling. It is also now possible to
3092 execute command reply functions from other command reply
3093 function as the function callbacks for commands and command
3094 replies are one and same. The pending commands are not static
3095 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3096 in client connection context. Thus, pending commands are server
3097 connection specific as it is convenient.
3099 Changed the function silc_client_command_pending and
3100 silc_client_command_pending_del and added new function
3101 silc_client_command_pending_check. Removed the
3102 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3105 * Added cmd_ident, current command identifier, to the client
3106 connection context in lib/silcclient/client.h to keep track on
3107 command identifiers used in command sending. Client's command reply
3108 function handling now supports the mandatory command identifiers.
3110 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3111 funtions in client to fully support pending command callbacks.
3113 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3114 as one of the arguments to the application in the command reply
3117 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3118 before first releasing SILC but came back. Now it is removed again
3119 and should come back nomore. The FORWARDED flag was used only
3120 by the JOINing procedure by forwarding the command packet to router.
3121 Now, the JOINing procedure has been changed to more generic (due
3122 to various router environment issues) and FORWARDED is not needed
3123 anymore for anything. The protocol specification is yet to be
3126 Now, removed silc_server_packet_forward from server and the flag
3127 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3129 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Renamed NAMES command to USERS command. The NAMES was named that
3132 due to historical reasons. Now it is renamed. Also, rewrote
3133 parts of the USERS command. The nickname list is not sent anymore
3134 by the server. Only Client ID and mode lists are sent in the USERS
3135 command. Changed this also to the protocol specification.
3137 The client now resolves the names and stuff after it receives
3138 the USERS list from the server when joining to the channel.
3140 * WHOIS and IDENTIFY commands has been changed to support multiple
3141 Client ID's per command. One can now search for multiple users
3142 in the network by sending only one WHOIS or IDENTIFY command.
3143 Changed the code and the protocol specifications.
3145 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3146 uses silc_server_command_whois_parse to parse the request. */
3148 * If normal server, do not parse the WHOIS and IDENTIFY requests
3149 before sending it to the router. Saves some time.
3151 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Fixed JOIN command on client library. Wrong number of arguments
3154 used to crash the client.
3156 * Added silc_server_channel_has_global function to check whether
3157 channel has global users or not.
3159 * Added silc_server_channel_has_local function to check whether channel
3160 has locally connected clients on the channel.
3162 * The silc_server_remove_from_one_channel now checks whether the
3163 channel has global users or not after given client was removed from
3164 the channel. It also checks whether the channel has local clients
3165 on the channel anymore. If it does not have then the channel entry
3166 is removed as it is not needed anymore.
3168 * The silc_server_notify now checks on JOIN notify whether the joining
3169 client is one of locally connected or global. If it is global then
3170 the channel has now global users on the channel and that is marked
3171 to the channel entry. Also, it now saves the global client to
3172 global list who is joining and JOINs it to the channel. This is
3173 for normal server, that is.
3175 Changed silc_server_send_notify_on_channel,
3176 silc_server_packet_relay_to_channel and
3177 silc_server_packet_send_to_channel check if we are normal server
3178 and client has router set (ie. global client) do not send the
3179 message to that client, as it is already routed to our router.
3181 * Implemented LEAVE notify type handling in silc_server_notify
3184 * Tested LEAVE command in router environment successfully. Tested
3185 with two routers, two servers and two clients.
3189 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3191 * Implemented SIGNOFF notify type handling in silc_server_notify
3194 * silc_server_remove_id now removes the client entry from all channels
3195 it has joined and thusly sends SIGNOFF notify type.
3197 * Rewrote the NAMES list generation in server by removing two excess
3198 loops. The lists are created now inside one loop.
3200 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * silc_server_remove_channel_user checks now also global list
3203 for channel and client.
3205 * silc_server_new_channel_user checks now both local and global
3206 list for channel and client. Fixed a bug in client id decoding.
3207 Used to decode wrong buffer.
3209 * silc_server_channel_message checks now both local and global
3210 list for channel entry.
3212 * Tested channel joining (hence JOIN) in router environment
3213 successfully. Tested with two routers, two servers and two
3216 * Tested channel message sending in router environment successfully.
3218 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Added silc_server_save_channel_key into server.[ch] to save the
3221 received channel key in Channel Key payload processing. It is
3222 also used in JOIN command reply handling.
3224 Equivalent function silc_client_save_channel_key added into
3225 client.[ch] into client library.
3227 * Changed JOIN command reply to send information whether the channel
3228 was created or not (is existing already) and the channel key
3229 payload. Changed protocol specs accordingly.
3231 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3232 the request was sent by ID and not by nickname. Crashed on
3235 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3238 now correctly save the received data.
3240 * silc_server_free_sock_user_data now notifies routers in the
3241 network about entities leaving the network.
3243 At the same time implemented functions silc_server_remove_id
3244 and silc_server_send_remove_id to receive and send REMOVE_ID
3245 packets. The packet is used to notify routers in the network
3246 about leaving entities. The ID removed will become invalid in
3249 * Added function silc_idlist_del_server into server. Removes and
3250 free's server entry from ID list.
3252 * silc_server_private_message function now checks, if we are router,
3253 that the destination ID really is valid ID, naturally.
3255 * In router when NEW_ID packet is received (for new client) the
3256 hash of the Client ID is saved in the ID Cache but the
3257 client->nickname is set to NULL, instead of putting the hash
3260 IDENTIFY command now also checks that client->nickname must be
3261 valid. If it is not if will request the data from the server who
3262 owns the client. Added new function
3263 silc_server_command_identify_check.
3265 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3266 to set the command to already allocated Command Payload.
3268 * Tested private message sending in router environment with two
3269 routers, two servers and two clients. Fixed minor bugs and now
3272 * Fixed segfault from client's NAMES command. Used to crash if
3275 * Forwarded packets must not be routed even if it is not destined
3276 to the receiver. Changed server code comply with this.
3278 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Added `require_reverse_mapping' boolean value to ServerParams
3281 structure. If TRUE (not default) the server will require that
3282 the connecting host has fully qualified domain name.
3284 If the reverse mapping is not required and hostname could not be
3285 found the IP address is used as hostname.
3287 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Implemented version string checking to both client and server.
3290 The check is incomplete currently due to the abnormal version
3291 strings used in development version of SILC.
3293 * Changed all command functions in server to use the new
3296 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Changed char *data to unsigned char *data in ID Cache system to
3299 support binary data as ID Cache data. Changed code to support
3300 binary data in lib/silccore/idcache.c.
3302 * Renamed silc_server_packet_relay_command_reply to
3303 silc_server_command_reply as it is normal packet receiving
3304 function. Rewrote the function to accept command replys for
3305 servers and not only for clients.
3307 * Mark remote router always as registered server if we are connecting
3308 to it. Otherwise, commands sent by the router to us are ignored.
3310 * All ID List find routines now returns the ID Cache Entry pointer
3311 as well if requested.
3313 * WHOIS command works now in router environment, tested with two
3314 routers, two servers and two clients.
3316 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3317 in router environment (as it is almost equivalent to WHOIS) but
3318 hasn't been tested thoroughly. Added new functions:
3320 silc_server_command_identify_parse
3321 silc_server_command_identify_send_reply
3322 silc_server_command_identify_from_client
3323 silc_server_command_identify_from_server
3325 * Disabled route cache adding because adding two different ID's with
3326 same IP replaces the old cache entry thus giving wrong route.
3327 The entry->router->connection is always the fastest route anyway
3328 so route cache may not be needed. Of course, new routes maybe
3329 established after receiving the ID when the entry->router->connection
3330 might not be anymore the most optimal.
3332 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Add route cache for received ID for fast routing.
3336 * Added silc_server_packet_route to route received packet on router
3337 that is not destined to us.
3339 * Renamed silc_server_get_route to silc_server_route_get.
3341 * Added id_string and id_string_len fields into SilcServer to
3342 include encoded ServerID for fast comparing without excess
3343 encoding of the ID's.
3345 * Cleaned up WHOIS command on server side. Added following static
3348 silc_server_command_whois_parse
3349 silc_server_command_whois_check
3350 silc_server_command_whois_send_reply
3351 silc_server_command_whois_from_client
3352 silc_server_command_whois_from_server
3354 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3355 arguments in command replies. All command functions should be
3356 updated to use this macro.
3358 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Minor typo fixes on command reply handling on server.
3362 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Added silc_server_command_add_to_channel internal routine to add
3365 the client to the channel after router has created the channel and
3366 sent command reply to the server.
3368 * Added generic silc_server_send_command to send any command from
3371 * Use static buffer with ID rendering instead of duplicating data.
3373 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Fixed a channel user mode bug when joining to a channel server gave
3376 everybody channel founder rights, oops.
3378 * We mark ourselves as the router of the incoming server connection
3379 if we are router ourselves. This way we can check in some packet
3380 sending functions whether it is locally connected server. For
3381 incoming router connections we put NULL.
3383 * For router sending packets locally means now always sending the
3384 packet cell wide; to local clients and local servers. For normal
3385 server sending packet locally means sending it to only local
3388 * Fixed the JOIN command to really work in router environment. If the
3389 channel is created it is always created by the router. Router is
3390 also responsible of making the initial joining to the channel,
3391 sending JOIN notify to the sending server and distributing
3392 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3393 does not exist server doesn't do anything else but forward the
3394 command to the router which performs everything.
3396 * Added silc_server_send_channel_key function to send the Channel Key
3399 * Added silc_server_create_channel_key to create new channel key. The
3400 channel key is now re-generated everytime someone joins or leaves
3401 a channel, as protocol dictates. Note: channel->key_len is the
3404 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3407 packet_receive.[ch] to separate packet sending and receiving
3408 routines. The server.[ch] now includes everything else including
3409 actual packet processing (writing and reading data) and other
3412 Renamed silc_server_private_message_send_internal to
3413 silc_server_send_private_message. The routine is still though
3414 used only to relay private messages as server does not send
3415 private messages itself.
3417 Renamed silc_server_new_channel to silc_server_create_new_channel
3418 and added new function sicl_server_new_channel that handles the
3419 incoming New Channel packet. Added also new sending function
3420 silc_server_send_new_channel to send New Channel Payload.
3422 * Added new function silc_server_notify to process incoming notify
3423 packet to the server/router. Server may then relay the notify
3424 to clients if needed.
3426 * Added new function silc_server_new_channel_user to process incoming
3427 New Channel User packet. Router will redistribute the packet and
3428 send JOIN notify to its local clients and locally connected servers
3429 if needed. Normal server will send JOIN notify to its local client
3430 on same channel when received this packet. Added also corresponding
3431 sending function silc_server_send_new_channel_user to sent the
3434 * Added boolean route argument to send_notif_to_channel and
3435 packet_send_to_channel functions to attempt to route the packet
3436 if it is TRUE and send only locally if it is FALSE.
3438 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * silc_server_replace_id now broadcasts the received replace ID
3441 packet if it is not broadcast packet already. The router must
3442 broadcast to inform other routers about changed ID.
3444 * Added backpointer to server's router into SilcServer context in
3445 silcd/server_internal.h.
3447 * Fixed silc_server_packet_broadcast to send correct broadcast
3450 * The channel key is now distributed to the local client as soon
3451 as it is received from the router (in router environment) so that
3452 no other packet may be sent for the channel until client has
3455 * silc_server_remove_channel_user now broadcasts the received
3456 Remove Channel User packet if it is not broadcast packet already.
3457 The router must broadcast to inform other routers about removed
3460 * Added users field into SilcPacketContext that is a reference count
3461 of the context. One can increase the reference count by calling
3462 silc_packet_context_dup which is now changed to just increase the
3463 reference count instead of duplicating the data. The reference
3464 count is decresed by calling silc_packet_context_free that will
3465 free the data after the reference count hits zero.
3467 For now on the packet context and everything allocated into it
3468 (including the raw packet from network) must be freed by calling
3469 the new silc_packet_context_free function. Added also new function
3470 silc_packet_context_alloc that must be used now to allocate the
3471 context. This also means that if a routine is asynchronous from
3472 silc_[client/server]_packet_parse_type the packet context must
3473 be duplicated by calling silc_packet_context_dup. Otherwise it
3474 gets free'd after silc_[client/server]_packet_parse_type returns.
3475 Also, one must remember that if packet is duplicated then its
3476 reference count must be decresed by calling the free function as
3477 many times as it was duplicated.
3479 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3480 from both client and server.
3482 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Made joining to a channel working in router environment.
3486 * Cleaned up JOIN command on server side and create function
3487 silc_server_command_join_channel internal routine to make the
3490 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Changed silc_command_pending list to SilcDList. Also, added
3493 `ident' field to SilcServerCommandPending structure to identify
3494 the reply and to call correct callback.
3496 Added silc_server_command_pending_check function to replace the
3497 corresnponding macro. The silc_command_pending list is not
3500 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3501 to set identifier to previously allocated Command Payload. It
3502 is used to set identifier for command when resending Command
3505 * Added silc_command_payload_encode_payload to encode Command
3506 Payload buffer from SilcCommandPayload structure.
3508 * Added silc_argument_payload_encode_payload to encode Argument
3509 payload buffer from SilcArgumentPayload structure.
3511 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Changed WHOIS command to support router connection on server side.
3514 The whois request is always sent to router unless the server is
3515 standalone server. After server has received the reply from the
3516 router will it send the reply to the client.
3518 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3519 broadcast received broadcast packet. The function is used only
3520 by router. The broadcast packet is always sent to the router's
3523 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3524 render given ID to printable string, for log files for example.
3526 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Made basic router to router connections working. At least they
3529 can now connect to each other but nothing really works the way
3530 they are supposed - yet.
3532 * Added new initiator token to RouterConnection configuration
3533 file in silcd/serverconfig.[ch]. It is used to tell whether we
3534 are the initiator to the remote router or whether we'll expect
3535 the other end to connect.
3537 * Moved registering of listener task to silc_server_init, hence
3538 the server starts listenning as soon as it is run, even if it
3539 does not have connections to other routers. Let's see how well
3542 * Changed default connection retry timeouts for more suitable in
3545 * Removed cipher and such arguments from silc_idlist_add_client
3546 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3547 Added new function silc_idlist_add_data to add the keys and stuff
3550 * Added SilcIDListData structure and added it to SilcClientEntry
3551 and SilcServerEntry as their first field in the structure. This
3552 way we can explicitly cast the ID entries to the SilcIDListData
3553 structure and get common data for the entries. In past, we had
3554 to first check what type of connection it is and then cast it to
3555 correct ID entry type. Now, we can directly cast the opaque
3556 pointer to the SilcIDListData (no matter what ID entry it actually
3557 is) and get the data needed.
3559 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3562 in some circumstances even if threre were timeout tasks, though not
3563 IO tasks, but tasks anyway. Now fixed.
3565 * Defined SilcServerConnection structure to hold connection specific
3566 stuff about directly connected servers and routers. The definition
3567 is currently in silcd/server_internal.h. I thought about having
3568 a bit more important role fro this struct but for now it is used
3569 only when connecting to other server (or router actually).
3571 * Added connecting retry support in server when connecting to
3572 router(s). The retry feature implement exponential backoff
3573 algorithm. Also, added SilcServerParams structure to hold default
3574 parameters for server. For now, it include these retry settings
3575 and are hard coded. After server is moded to be as Silc Server
3576 Library this structure will be more important.
3578 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Changed client librarys channel->clients table to SilcList and
3581 changed code accordingly.
3583 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Changed client's channel table to SilcList and changed code
3586 accordingly. Also changed SilcChannelClientEntry to include back-
3587 pointer to the channel so that client entry can use that structure
3588 as list as well and we have fast cross-reference to the channel.
3589 This change dramatically decreased the complexity of channel
3590 handling with client entry and vice versa (removed one extra
3591 loop when searching for channel entry from many functions).
3593 * Changed server->sim from table to SilcDList and changed code
3596 * NAMES command can now be used from user interface. It will show
3597 the user list on the channel, neatly.
3599 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3600 Code now saves realname of the user if it becomes available.
3602 * Renamed configure.in to configure.in.pre and made ./prepare
3603 script to automatically add correct version string to
3604 configure.in which it creates from configure.in.pre.
3606 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * NAMES command reply now shows users mode with the nickname when
3611 * Moved silc_client_ch[u]mode[_char] functions from
3612 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3613 place sucks, they are utility functions and should be in some
3616 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3618 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3621 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Added TRQ (efficient deque and list library) into lib/trq. This is
3626 a very good list library that is currently used in the SILC. Defined
3627 SilcList API over the library because I didn't like the API very
3628 much. See lib/trq/silclist.h for the API and examples of how to
3629 use the API. Fixed various places in the code to use the new
3630 SilcList API. The SilcList is meant for lists that has a structure
3631 already defined as a list. It is not suitable to add just some
3632 context to the list (in TRQ, the context is the list actually).
3634 So, I defined SilcDList that can be used for the purpose where
3635 predefined list structure does not exit. This can be used as
3636 such list. Now some context just can be added to the SilcDList.
3637 Currently this list is not used in the SILC just yet, though there
3638 are a lot places where this can replace dynamically allocated
3639 tables and I will fix these places, later, to use SilcDList.
3640 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3641 and use TRQ internally).
3643 Also fixed some annoying warning messages that the original TRQ
3644 code generated. Also minor changes to TRQ's Makefile.in.
3646 * Added support for querying by Client ID to both WHOIS and
3647 IDENTIFY commands into server, as required by the protocol.
3649 * Removed method function pointers from SilcBuffer structure. They
3650 weren't used to anything and just increased the context size for
3651 no good reason. This change also made silc_buffer_alloc and
3652 silc_buffer_free functions inline functions.
3654 * Disabled command flooding detection support until it's fixed so
3655 that it accepts commands in but does not execute them more than once
3658 * Added silc_net_localhost(), to return local hostname, into
3659 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3660 that must be initialized before calling silc_client_init.
3662 * Added new function: silc_server_send_notify_on_channels to send
3663 notify messages to all channels client has joined. It is assured
3664 that the message is sent only once per client.
3666 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3667 lib/silcutil/silcutil.[ch] as silc_format function. The new
3668 function is generic and is used by server as well, not only by
3669 the logging routines.
3671 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3672 the provided version string was not acceptable. Added new function:
3673 silc_ske_check_version into lib/silcske/silcske.h. The function
3674 must be implemented by the application (client or server) and it
3675 does not reside in the SKE library. The function checks the version
3676 string remote end sent.
3678 * Added back pointers (to opaque context and to SilcSocketConnection)
3679 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3681 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3682 duplicate packet context structure.
3684 * Changed `notify' client operation to send same arguments as client
3685 receives from server except for ID's. ID's are mapped to correct
3686 ID entry and that is returned. Also, if channel entry is not sent
3687 by server but the notify is for channel the channel entry is sent
3688 to application (otherwise application doesn't know that it is for
3689 channel (library gets it from packet's Destination ID)).
3691 * Added silc_client_remove_from_channels into client library to
3692 remove a client from all channels it has joined to. Used when
3693 received SIGNOFF notify from server. Added also new function
3694 silc_client_replace_from_channels to replace old ID entry with
3695 new ID entry on all channels. Used when received NICK_CHANGE
3698 * Fixed ID Cache list handling in silc_idlist_get_client in
3699 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3700 to get (or query) client by ID.
3702 * Updated TODO list.
3704 * Added connection authentication status message defined by the
3705 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3706 support for these into the code in client and server side.
3708 * Added generic function silc_client_send_command to send any command
3709 with variable argument list. Application should use this function
3710 to send commands if the command functions provided by the library
3711 does not suite for the application's user interface needs.
3713 * Added new `failure' client operation. Application is notified about
3714 received failure packet if client is executing a protocol. In this
3715 case the protocol's execution has failed.
3717 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3718 is required by the protocol.
3720 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3721 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3724 * Added status flag to SilcSKE object to indicate realtime status
3725 of the SKE protocol.
3727 * Application receives now exactly same command reply arguments as
3728 the library receives from server. However, if ID is received the
3729 corresponding ID entry is returned to the application (eg. Client
3730 ID is mapped to correct SilcClientEntry entry and that is returned).
3731 Changed command_reply client operation due to this change.
3733 * Changed all ID's in commands and in command replys as ID Payloads.
3734 Change affected both client and server side codes.
3736 All ID's sent in SILC network (with execption of ID's in SILC
3737 Packet header) are sent in ID Payload to support variable length
3740 * Server now notifies nick changes and notifies all clients on
3741 the channels about the new nickname (about the new Client ID,
3744 * Implemented CMODE command to change channel modes. Supports all
3745 channel modes defined by the protocol specs except ban and invite
3746 lists. (Also, private channel key mode is supported but support for
3747 setting private channel key in client is missing, thus, this mode
3748 has no effect on client side (except that server requires that the
3749 client uses private channel key and normal channel traffic does not
3752 Also, invite mode works per se, but INVITE command does not work
3753 yet correctly, so you can set channel as invite only channel but
3754 inviting clients to the channel does not work (it is yet to be
3755 thought what's the best way to do it).
3757 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3758 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3759 Implemented CUMODE command to change user's mode on the channel.
3760 Supports all modes defined by the protocol specs.
3762 * Added NAMES command reply to return users modes on the channel.
3764 * Removed unnecessary and slow ciphers from lib/silccrypt.
3766 * Set SO_KEEPALIVE option to connection sockets by default.
3768 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3770 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3771 redefined the Notify Payload into protocol specs.
3773 * Added silc_id_payload_parse_id to get ID directly from raw
3776 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3779 accept searching by Client ID as well.
3781 * Added support for LEAVE and SIGNOFF notify types in client library.
3783 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3784 to parse ID Payload from raw data.
3786 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Added flags parameter into silc_ske_assemble_security_properties
3789 function in lib/silcske/silcske.[ch].
3791 * Changed notify client operation to fit better for notify messages
3792 sent by server. The notify payload received from server is now
3793 passed to the application (after parsing it to SilcNotifyPayload).
3794 It is application's responsibility to retrieve the arguments
3795 from the payload and show the message the way it wants. The message
3796 sent by server is implementation specific.
3798 * Changed public keys to comply with the protocol specification.
3799 Old public keys are not supported anymore and are not compatible.
3801 * Removed nickname from Channel Payload as the latest draft removed
3802 it. The client must resolve the nickname from the NAMES command
3803 reply received when it joined the channel.
3805 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3807 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Fixed some errors in protocol specification drafts.
3811 * Created lib/silccore/silcnotify.c to implement Notify Payload
3812 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3813 generic payloads described by protocol specifications. The file
3814 includes implementations for ID Payload and Argument Payload.
3816 * Changed Command Payload implementation to use the new Argument
3817 Payload. Changed command_xxxx_payload to command_payload_xxxx
3818 to comply with SILC coding conventions.
3820 * Added suppport for Argument Payload handling in Notify Payload
3821 implementation as protocol requires it. Added the new support
3822 into server and client lib as well.
3824 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Added support for multiple nicknames on same channel. [n] is
3827 added locally to the nickname if there are more than one same
3828 nicknames on the channel.
3830 * Server now sends all nicknames that matched WHOIS request.
3831 Client also shows the list received from server.
3833 * Added TOPIC command to client side. User can now set and show
3834 current topic on channel.
3836 * Added MOTD command to client and server. Also, server sends the
3837 motd when client connects to the server.
3839 * Changed version strings to comply ISO 8601.
3841 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Fixed protocol error handling in client library. It should now
3844 cope even if the SKE fails for some reason.
3846 * Made new protocol specification drafts for submitting to IETF.
3848 * Implemented TOPIC command to server in silcd/command.c.
3850 * Added two new notify types into lib/silccore/silcnotify.h:
3851 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3852 notify nickname change and topic setting/change on a channel.
3854 * API change of command_reply operation in client library. The
3855 application gets now the status type received from server as well.
3857 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3861 * Cras fixed and optimized the packet handling even further and
3862 it should work now. Minor change to the prototype of function
3863 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3865 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added new function into lib/silcutil/silcschedule.[ch]:
3868 silc_schedule_with_fd to select() a specified fd. The function
3869 returns after timeout expires or data arrives or goes. The
3870 function is used by packet routines to wait that all data is
3871 received from network.
3873 * Fixed data reading from network in lib/silccore/silcpacket.c.
3874 The code now assures that all data is read from the fd and then
3875 continues packet processing. This was a bug fix since the code
3876 used to drop some data in some circumstances.
3878 * Added new function into lib/silcclient/client.[ch]:
3879 silc_client_start_key_exchange to start key exchange after
3880 connection has been established to server. The code internally
3881 now uses this funtion but its main purpose was to provide it
3882 for applications that perform their own connecting. After
3883 application has created a connection it merely calls this
3884 function to start the key exchange between client and server.
3885 The library takes care of everything else after that.
3887 Updated also lib/silcclient/README to explain the usage of
3890 * Do not send to application information that connection has
3891 been established. Application gets notified it by connect
3894 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Applied cras's patch to add silc_schedule_one function. The
3897 function runs scheduler once and returns.
3899 * Fixed the scheduler after cras messed it up. The timeout
3900 handling works now as it's supposed to work.
3902 * Added into lib/silccore/ silcnotify.h to include notify
3903 message types support. Changed silc_server_send_notify*
3904 functions, in server.[ch], to support those new notify types.
3905 Added the support for the notify types into client library,
3906 as well. Added new notify client operation into ops.h in
3909 * Changed silc_server_packet_send_to_channel to send normal
3910 packets instead of just channel message packets. The function
3911 is now used to send the notify packets to channels. It is not
3912 used to send channel message packets anymore, as server never
3915 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3916 va_arg()s as it seems to require it nowadays. I guess, if SILC
3917 is compiled with older va_arg() the new code should work anyway.
3919 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Splitted core library. Core library (lib/silccore) includes
3922 now only SILC protocol specific core (and common) components.
3923 Created new utility library (lib/silcutil) that includes more
3924 generic purpose stuff. The stuff for util library was taken
3925 from the old core library. This was minor and easy split.
3927 * Created SILC Client Library (lib/silcclient) that includes
3928 implementation of the SILC client without user interface. This
3929 was major move from silc/ directory. The code has been changed
3930 so that it is transparent towards the user interface. The
3931 silc/ directory includes now the same user interface as before
3932 and it uses the new client library. Read lib/silcclient/README.
3933 Basicly, the client library performs everything else related
3934 to SILC except user interface handling. Also, configuration
3935 files are considered to be part of user interface and library
3936 does not handle them.
3938 This change also changed a lot of structures, function naming etc.
3939 Most important change was that SilcClientWindow object was
3940 renamed to SilcClientConnection in the client library. Created
3941 also new file lib/silcclient/ops.h. Also added new files
3942 silc/local_command.[ch] and silc/client_ops.[ch].
3944 All these changes were made to make it easier for user interface
3945 designers to create what ever user interface for the SILC client
3948 It is also expected that the server will be moved to lib
3949 directory as well and SILC Server Library will be created;
3950 sometimes in the future.
3952 * Removed Local commands from lib/silccore/silccommand.h as
3953 they are application specific and new client library does not
3954 handle any of those anymore.
3956 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3957 old client implementation in silc/.
3959 * Added support for callback functions in SILC_LOG_* macros.
3960 Application can now set its own callbacks that will be called
3961 instead of using the default functions that will always print
3962 the debug messages to stderr (or stdout). Also, debugging can
3963 now be disabled by setting silc_debug to FALSE and re-enabled by
3964 setting it to TRUE. Note, that logging will still work even
3965 if debugging is disabled.
3967 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3968 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3969 silc_log_reset_debug_callbacks.
3971 * To enable debugging in silc client one must give now -d
3972 option on command line.
3974 * Changed silc_schedule_init to automatically allocate task queues
3975 if they are not allocated before calling it.
3977 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added GMP 3.1 into math library.
3981 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3984 a channel in SILC network. The packet is used by servers and
3985 routers to notify other routers that user has left a channel.
3986 This little feature was missing until now. Added the feature
3987 to protocol specification as well.
3989 Added functions: silc_server_send_remove_channel_user and
3990 silc_server_remove_channel_user into server.[ch].
3992 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3993 lib/silccore/silcpacket.h. However, they are not implemented
3996 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Fixed joining to a channel and sending channel messages
3999 between server and router. The channel message sending should
4000 now work inside a cell.
4002 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Fixed the private message sending between server and router.
4005 The private message sending should now work inside a cell.
4007 * Added silc_server_replace_id into server.[ch] to replace
4008 existing ID in the SILC network.
4010 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4011 and silc_idlist_replace_server_id into idlist.[ch] in server.
4013 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Fixed the server to server connections. Server can again now
4016 connect to router. Router to router connections probably does
4019 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Added dynamic protocol registering support. Now protocols can
4022 registered and unregistered on the fly. Patch by cras.
4024 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Added lib/contrib directory to hold routines that some platforms
4027 don't have but are needed by SILC.
4029 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4030 into lin/contrib to provide getopt() and getopt_long() for
4031 those who don't have it.
4033 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added AWAY command to client. When away message is set and
4036 client receives a private message packet the client automatically
4037 replies to the sender with the away message.
4039 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4040 bug seemed to be the cause of recent problems when compiling
4043 * Added version detection support to SKE protocol specification
4044 and added the new changes to the SKE implementation as well.
4045 There were other minor changes in the SKE protocol as well.
4047 Many changes in lib/silcske/silcske.[ch] and in
4048 lib/silcske/payload.[ch].
4050 * Added ^U functionality, clear input line. Patch from cras.
4052 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Mainly small bugfixes on core library. Fixed some debugging
4055 logging and buffer overflow in silclog.c.
4057 * Updated config.sub and config.guess on the distribution tree.
4059 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Added command lagging support in server. Client may execute
4062 commands now only once in two seconds.
4064 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Optimized packet reception. MAC computation and checking is now
4067 also more optimized. A lot previously duplicated code is now
4068 used as generic by both client and server.
4070 * Fixed key pair generation in clientutil.c
4072 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Added into lib/silccore/silcbufutil.[ch] new function;
4075 silc_buffer_realloc.
4077 * Moved generic packet sending/encryption functions to
4078 lib/silccore/silcpacket.[ch] from client and server. Some
4079 rewriting of the functions.
4081 * Moved all generic packet reception/decryption functions to
4082 lib/silccore/silcpacket.[ch] from client and server. The
4083 packet processing is now much cleaner in both client and server.
4084 These were major changes in both client and server.
4086 * Created many common functions in server to do packet sending.
4087 Previously code were duplicated a lot, this has been removed
4090 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Rewrote major parts of the ID cache system. Don't know
4093 whether it is better now or not but at least the API is more
4096 * Major rewrite on ID cache stuff on client because of the ID
4097 cache API changes. Added idlist.c to client.
4099 * Also major rewrite on ID cache stuff on server as well.
4100 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4101 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4102 in hand, instead they are all put into the ID cache system now.
4103 All server_idlist_* routines uses ID cache now instead of
4104 traversing its own lists (those lists does not exist anymore).
4105 SilcIDList though still exists. Also, SilcXXXEntry's are
4108 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Finally made the SKE implementation compliant to the protocol
4111 specification. All mp integers are now binary encoded as
4112 opposed being HEX encoded.
4114 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4117 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4118 functions: silc_[encode/decode]_pem. Also added function
4119 silc_encode_pem_file to PEM encode with newlines ('\n') for
4122 * SILC public keys are now encoded either PEM or binary. Same
4123 option is for private keys as well. By default private keys
4124 are binary encoded and public keys PEM encoded. Silly HEX
4125 encoding were removed.
4127 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4128 function to create fingerprints.
4130 * Fixed a bug in SHA1; does not change the original data anymore.
4132 * Partly implemented INFO command on client and server side.
4133 Fixed CLEAR command. Changes to SERVER command; show current
4134 server(s) when giving command without arguments. Added
4135 VERSION command to client.
4137 * Added check to server that unregistered connections cannot
4138 execute commands (unless it is specificly allowed).
4140 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Fixed screen refresh.
4144 * Fixed channel joining bug from client. On some circumstances
4145 client tried to join to a channel it had already joined.
4147 * Added public key verification process into client's protocol.c.
4148 The client now verifies the public key from user and saves
4149 it into ~./silc/serverkeys/ directory.
4151 Added into: clientutil.[ch]: silc_client_verify_server_key.
4153 * Changed SKE protocol's silc_ske_initiator_finish function
4154 to accept callback function that verifies the received public
4155 key. Removed old silc_ske_verify_public_key function.
4157 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4160 silc_pkcs_private_key[_data]_set.
4162 * Made the password and public authentication more cleaner in
4163 server's protocol.c.
4165 * Removed historic and obsolete protocol `channel_auth' from
4166 both client and server.
4168 * Removed wrong way of sending command status messages from
4169 server to client in server's command.c. The old way violated
4170 protocol specification.
4172 Changes to silccore/silccommand.[ch]: removed
4173 silc_command_encode_status_payload -> not needed anymore,
4174 changed silc_command_encode_payload_va to accept extra
4175 argument on variable argument list. The argument type must
4176 now be provided to the function. Also, added new function:
4177 silc_command_encode_reply_payload_va which is same as
4178 normal command_encode_payload_va except command status type
4179 is provided as extra argument.
4181 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Added ~./silc directory handling. The directory includes the
4184 public and private keys for the client.
4186 Added silc_client_check_silc_dir, silc_client_create_identifier
4187 and silc_client_load_keys.
4189 * Implemented SILC protocol compliant public key. Added public
4190 and private key saving to and loading from files.
4192 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4193 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4194 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4195 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4196 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4198 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4199 silc_pkcs_load_[public/private]_key.
4201 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Added silc_server_get_route (route.[ch]) to get connection
4204 data for the fastest route for given ID.
4206 * Implemented INVITE command on client and server. The command
4207 were re-defined in the SILC Protocol Specification and the
4208 implementation now complies with the specification.
4210 * Implemented PING command on client and server.
4212 * Implemented NAMES command on client and server. The server side
4213 supports currently only normal server not router server yet.
4214 Some changes to NAMES definition in SILC protocol specification.
4216 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Implemented LEAVE command on client and server.
4220 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4221 again. This change was made to the protocol as well. Server
4222 should not violate the protocol specification anymore.
4224 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4227 was tested. SOCKS4 was not but should work anyway.
