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 * Added Unix specific utility functions from the
23 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
25 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
27 * Do not handle JOIN notify in the server if the target client
28 is not registered (idata->registered == FALSE). The affected
29 file is silcd/packet_receive.c.
31 * Update the nickrec->founder in event_cumode in the Irssi SILC
32 client. Affected file irssi/src/silc/core/silc-channels.c.
34 * Fixed the CUMODE_CHANGE notify handling in the server when
35 server and router are announcing their clients on channels.
36 Now the mode changes are saved and notified correctly. The
37 affected file is /silcd/packet_receive.c.
39 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
40 They really did not replace the cache entry in the ID Cache.
41 Now they do that. Affected file silcd/idlist.c.
43 * Fixed the KICK notify handling in the Irssi SILC client to
44 update the channel records so that the kicked client does not
45 appear to be on the channel. The affected file is
46 irssi/src/silc/core/silc-channels.c.
48 * Always update the conn->current_channel when executing command
49 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
51 * Fixed the KILL notify handling in Irssi SILC client to remove
52 the killed client on all channels.
54 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Fixed the silc_parse_command_line to remove extra spaces
57 from the start and end of the arguments. Affected file is
58 lib/silcutil/silcutil.c.
60 * Cancel and free any active protocol in the function
61 silc_server_close_connection. Affected file silcd/server.c.
63 * Cancel and free any active protocol in the function
64 silc_client_close_connction. Affected file is
65 lib/silcclient/client.c.
67 * Do not execute the KILL command for clients that are in
68 history (ie. they are not in the network). Affected file is
71 * Fixed KILL notify handling, client does not crash anymore.
72 Affected file irssi/src/silc/core/silc-channels.c.
74 * Reduced the default packet buffer size from 2048 to 1024 in
75 lib/silccore/silcpacket.c.
77 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
78 counter to the SKE context that is incresed when the SKE library
79 performs async operation outside the library. If the outside
80 process frees the SKE context and FREED status will be set
81 and the library will detect after the sync operation that the
82 libary is freed. The affected files are
83 lib/silcske/silcske[_status].[ch].
85 * Resolve the client entry information in the function
86 silc_client_channel_message to assure that NULL pointer is not
87 passed as client entry to the application. */
89 * Fixed the task timeout calculation to assure that there is
90 never negative timeouts. The affected file is
91 lib/silcutil/silcschedule.c.
93 * Fixed the channel user mode notification sending in server.
94 It was sent point-to-point to the router (or to server by router)
95 but it needs to be destined to a channel. The routines now
96 supports sending the channel user mode notifys to the channels
97 when announcing clients and channels. Affected files are
98 silcd/server.c and silcd/packet_receive.c.
100 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
101 It did not actually replace the old channel entry in the cache.
102 Affected file lib/silcclient/client_notify.c.
104 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Fixed a possible crash in silc_packet_send_prepare. It now
107 assures always that there is enough space in the buffer and
108 at the tail area of the buffer (for MAC).
110 Fixed the inbound buffer reallocation in silc_packet_read.
111 It was old code and did not handle the reallocation correctly.
114 The affected file is lib/silccore/silcpacket.c.
116 * Fixed buffer overflow in silc_parse_nickname in the file
117 lib/silcutil/silcutil.c.
119 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * make install generates new server keys only if there is not
124 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
127 Added check that if the NOREPLY is set then we will not send
128 the away message. This avoids infinite loop of away messages
129 if both clients are away. The affected file is
130 lib/silcclient/client_prvmsg.c.
132 * Fixed client crash if /NICK was given without arguments.
133 Affected file lib/silcclient/command.c.
135 * Server does not send the invite list in INVITE command back
136 to the client if the list was not altered. Added this notion
137 to the protocol spec as well. Affected file silcd/command.c.
139 Fixed possible crash in INVITE command by checking the
140 value of silc_server_get_client_route command.
142 * Fixed the INVITE notify type handling. The arguments are now
143 taken in correct order and client does not crash. The affected
144 file is irssi/src/silc/core/silc-channels.c.
146 Removed the "Inviting xxx to channel" message from the
147 client library away and let the application handle it.
148 Affected file lib/silcclient/command.c. Added that message
149 to Irssi SILC client's message formats.
151 * Fixed CMODE command crash in client. It now checks the
152 amount of arguments correctly and does not crash. The affected
153 file is lib/silcclient/command.c.
155 * Do not create new channel automatically in silc_channels_join
156 but check whether the channel by that name already exists.
157 Affected file irssi/silc/core/silc-channels.c.
159 * Do not send the SERVER_SIGNOFF to router if the disconnected
160 entity was the router. Affected file silcd/server.c.
162 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
163 SILC client as it was missing from there.
165 Added the handling of the KICK notify to the Irssi SILC client
166 as it was missing. Added "you have been kicked" message to
167 Irssi SILC client's message modules formats.
169 Added the handing of the KILL notify to the Irssi SILC client
170 as it was missing. Added the kill message module formats
173 The affected file is irssi/src/silc/core/silc-channels.c.
175 * The router did not save the channel mode the server announced.
176 Affected file silcd/packet_receive.c.
178 * Fixed a possible crash in INFO command in server. If the
179 server did not provide the server info it crashed. Affected
180 file silcd/command.c.
182 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Fixed the GETKEY command in the server to check also the
185 global list. Otherwise the GETKEY would not work correctly
186 in normal SILC server. Affected file silcd/command.c.
188 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * Fixed GETKEY crash, it crashed if the command did not succseed.
192 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
194 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
195 is now real and not just an macro interface to GMP.
197 Removed the entire GMP from the source tree and imported new
198 NSS MPI library instead. Reason for removing GMP is that it is
199 extremely large and compiles extremely slow. The NSS MPI
200 is only a few files and compiles in less than 10 seconds.
201 The speed is also about the same as GMP. The MPI is imported
204 If the system has GMP installed we will still use the GMP.
205 If it is not then the NSS MPI will be compiled.
207 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Merged a long nickname (127 characters long) crash bugfix from
210 Irssi CVS tree. Affected file irssi/src/core/misc.c.
212 * Merged a freed memory reference bugfix from Irssi CVS tree.
213 Affected file irssi/src/core/commands.c.
215 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
217 * Added the server's public key sving and verification to the
218 server when performing the SKE. This was missing and the
219 remote server's (or router's) public key was accepted without
220 checking whether we have it previously or trust it at all.
221 Affected file silcd/protocol.c.
223 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Check in the silc_server_timeout_remote if protocol is active
226 and make sure that the protocol's final callback is called so
227 that all memory if freed. Affected file silcd/server.c.
229 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * silc_server_whois_send_reply crashed the server if the nickname
232 was 127 characters long. Affected file silcd/command.c.
234 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Added sanity check to the silc_server_new_client. If the hostname
237 is provided inside username then check that the provided hostname
238 really is the same as the resolved one. If the hostname was not
239 resolved then check it from the public key. Affected file is
240 silcd/packet_receive.c.
242 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
243 if the server disconnected us and the connection is not valid
244 anymore. Affected file irssi/src/silc/core/silc-channels.c.
246 * Moved the silc_client_[chmode|chumode|chumode_char] away from
247 the library to the lib/silcutil/silcutil.[ch].
249 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Close log file after open. Affected file
252 lib/silcutil/silclog.c.
254 * Check whether sock == NULL in silc_client_send_packet and return
255 if it is. Affected file lib/silcclient/silcclient.c.
257 * Check rec->entry == NULL in the Irssi SILC Client before
258 sending the channel message. Affecte file is
259 irssi/src/silc/core/silc-servers.c.
261 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Merged a splitted window bugfix from Irssi CVS tree. The
264 affected file is irssi/src/fe-text/textbuffer-view.c.
266 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
267 It did not print nickname.
269 * Improved the distributions system a bit.
271 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
273 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
274 irssi/src/fe-text/gui-window.c.
276 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
277 to in-active server. The affected file is
278 irssi/src/silc/core/client_ops.c.
280 * Resolve the client in USERS command reply if the entry does
281 not have username resolved. The affected file is
282 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
283 command to WHOIS command to really resolve stuff. The USERS
284 is not used any more in any critical section so WHOIS can
285 be used even though it might be slower than IDENTIFY.
287 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
290 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Changed the protocol API a bit more consistent in the
293 lib/silccore/silcprotocol.[ch].
295 * Changed the following headers to ROBODoc format:
297 lib/silccore/silcpayload.h
298 lib/silccore/silcprotocol.h
299 lib/silccore/silcsockconn.h
301 All core library headers are now formatted.
303 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Fixed a bug in Irssi SILC client; do not show that you are
306 server/router operator if you really are not. Affected file is
307 irssi/src/silc/core/client_ops.c.
309 * Renamed silc_command_free_payload to silc_command_payload_free.
310 Affected file lib/silccore/silccommand.h
312 * Added silcmath.h to include the prototoypes of various routines
313 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
316 * Changed the following headers to ROBODoc format:
318 lib/silccore/silcchannel.h
319 lib/silccore/silccommand.h
320 lib/silccore/silcid.h
321 lib/silccore/silcidcache.h
322 lib/silccore/silcmode.h
323 lib/silccore/silcnotify.h
324 lib/silccore/silcpacket.h
325 lib/silcmath/silcmath.h
327 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Added checking to the server code not to start the server if
330 ciphers and stuff are not configured properly. Affected files
331 silcd/serverconfig.[h] and silcd/server.c.
333 * Changed the layout of the header files of the public interfaces
334 in the SILC libraries. The new layout supports ROBODoc
335 documentation tool (and some others) so that it is easy to create
336 a library reference manual. All the other headers and source
337 code must still follow the CodingStyle document. Also source
338 code must not include these ROBODoc stuffs, only the headers.
339 Furthermore, all public interface headers must now be named
340 by using `silc' prefix, example: silcapi.h, silccipher.h.
341 Some files were renamed due to this. All the other headers
342 must not be used as public interfaces. I will update the
343 CodingStyle document later. Changed following headers, so far:
345 lib/silcclient/silcapi.h
346 lib/silccore/silcauth.h
347 lib/silccore/silcprivate.h
348 lib/silccrypt/silcdh.h
350 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * Removed silc_client_packet_send_flush from the client library
355 as it is not needed. Affected file lib/silcclient/client.[ch].
357 * Added printing of message of unresolved authentication method
358 to the Irssi SILC client. Added it to the module formats.
359 Removed the same message from the client library.
361 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added new distribution feature, DISTLABEL. Every distribution
364 can define own preprocessor label that can be used in the
365 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
366 file distributions, acconfig.h.pre and prepare.
368 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
370 * Added Makefile.defines_int to include the actual definitions
371 for Makefile.defines.in. Tested the new distribution system,
372 created distributions and tested installation.
374 * Added AWAY message printing to the Irssi SILC client. Added
375 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
377 * Added SCONNECT command to call the SILC's CONNECT command.
378 Cannot use CONNECT directly since Irssi uses that internally.
379 Affected file irssi/src/silc/core/silc-servers.c.
381 Added ACTION local command. It is same as ME command but takes
382 the channel as mandatory argument.
384 Rewrote some of the Irssi's help files to suite for SILC
387 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Added Makefile.defines[.in] that should for now on be included
390 in all Makefile.am file in the source tree. That file includes
391 all common compilation definitions for SILC source tree.
393 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
395 * Minor changes to the ./prepare script to change the package
396 name according the distribution name to the configure.in.
398 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Created new distribution system. Added file `distributions'
401 that defines all the distributions that can be created out of
402 the SILC source tree. The ./prepare script now reads that
403 file to determine how to prepare the distributions. The
404 first argument to the ./prepare is the name of the distribution
405 and second is the version of the distribution. If given
406 without arguments it creates the default (toolkit) distribution
407 with the default version (defined in ./prepare).
409 All Makefile.am files that are subject to the distributions
410 are now named as Makefile.am.pre. These are ./Makefile.am
411 and lib/Makefile.am. Others may be changed later.
413 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Added invite list, ban list, some key management and connection
416 error message printing to module formats in the Irssi SILC client.
418 * Added new silc_client_set_away_message to set the away message
419 that is back to the person who sent private message. The
420 affected file lib/silcclient/silcapi.h and the
421 lib/silcclient/client_prvmsg.c.
423 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
425 * Fixed the private message sending in the Irssi SILC client,
426 added local command KEY to the Irssi SILC client.
428 Added key management and key agreement message formats to the
429 irssi/src/fe-common/silc/module-formats.[ch].
431 Added USERS (alias WHO) printing, server/router operator
432 indication and LIST command printing to the module formats.
434 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * Fixed channel joining notify handling, cumode notify handling
437 from Irssi SILC client.
439 * Added SILC specific module-formats to the Irssi SILC client so
440 that SILC specific message hilighting, colors etc is possible.
441 Affected file irssi/src/fe-common/silc/module-formats.[ch].
443 Added channel mode, channel user mode, actions, notices,
444 whois and whowas printing to the the module-formats.c.
446 * Fixed a bug in channel deletion in the server. The channel
447 is not left to the cache even if the channel founder auth mode
448 is set when there are no users anymore on the channel. Affected
451 * The silc_net_localhost now resolves the entire hostname including
452 the domain name. Affected file lib/silcutil/silcnet.c.
454 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Changed the ask_passphrase client operation to be ascynchronous.
457 It has now a completion callback and a context that the
458 application must call after it has got the passphrase from
459 the user. Affected files lib/silcclient/silcapi.h,
460 lib/silcclient/protocol.c, lib/silcclient/command.c and
463 Added SilcAskPassphrase callback that the application calls
464 to deliver the passphrase to the library.
466 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
467 The public key verification and especially a certificate
468 verification is asynchronous procedure.
470 Added new SILC_SKE_STATUS_PENDING status to indicate the
471 request is pending and a callback will be called to finalize
474 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
475 indicate that remote end did not send its public key (or
476 certificate), even though we require it. Added check for this
477 condition in the SKE. This was a security bug, now fixed.
479 Defined new SilcSKEVerifyCbCompletion callback that is called
480 when the verification process is completed.
482 The affected files lib/silcske/silcske_status.h and
483 lib/silcske/silcske.[ch].
485 * Changed the verify_public_key client operation to be async
486 as well. Defined SilcVerifyPublicKey callback that is used to
487 indicate the success of the public key verification process.
489 Changed the server and client to use the new async client
492 * Changed the Irssi SILC client's internal scheduler to be called
493 twice as many times as it used to be. As a result the client
494 should be a bit faster now. Affected file is
495 irssi/src/silc/core/silc-core.c.
497 * Added support to Irssi SILC client of asynchronous public key
498 verification and passphrase inquiry. Affected file is
499 irssi/src/silc/core/silc-core.c.
501 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Do not say "You have left channel %s" in client library.
504 Moved it to the application. Affected files are
505 lib/silcclient/command.c and silc/client_ops.c.
507 * Fixed silc_client_get_clients. Command context was not
508 duplicated and was freed memory in the callback. Affected
509 file lib/silcclient/idlist.c.
511 * Do not say "you are now talking..." on JOIN command in the
512 client library. The appliation must handle it.
514 * Do not say ".. changed topic to" in command reply in the
515 client libary. The application must handle it.
517 * Fixed TOPIC command sending in the client library.
519 * Fixed a memory leak in silc_client_command_free in the file
520 lib/silcclient/command.c.
522 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
524 * Imported a modified version of Irssi client to the source tree.
525 The Irssi will be used to create a new client called
526 Irssi SILC. Imported to irssi/.
528 Added silc_core_init_finish function to the Irssi. Affected
529 file irssi/configure.in.
531 A lot changes in the Makefile.ams around the irssi tree.
533 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Do not rehash if the new size is same as the old size of the
536 hash table, in the silc_hash_table_rehash*. The affected file
537 lib/silcutil/silchashtable.c.
539 * Replaced hash_table_del_by_context calls from the server
540 (when channel->user_list and client->channels) to the
541 hash_table_del as it is sufficient and faster.
543 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * Added silc_hash_table_list, silc_hash_table_get and the
546 SilcHashTableList structure to provide an alternative way to
547 traverse the hash table. The affected files are
548 lib/silcutil/silchashtable.[ch].
550 * Changed the server's idlist routines to use the hash table
551 routines to optimize the code.
553 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
555 * Replaced the client entry's `channel' list and channel entry's
556 `user_list' list to hash tables for optimized lookup. Changed
557 the code to use the hash table interface around the code.
558 Affected file lib/silcd/idlist.[ch].
560 * Added `auto_rehash' boolean argument to the function
561 silc_hash_table_alloc to indicate whether the hash table should
562 auto-rehash when it thinks is appropriate time. It will
563 increase the hash table size if the there is twice as much
564 entries in the table than the size of the table, and will
565 decrease the size if there are twice as less entries than
566 the size of the table.
568 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Fixed silc_xxx_get_supported to not crash at some circumstances.
572 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * silc_idcache_purge_by_context deletes the entry now by context
575 as it is supposed to do. Affected file lib/silccore/idcache.c.
577 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
578 client is not anymore valid (WHOWAS givens the info) and not
579 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
581 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Removed the `data' and `data_len' arguments from the ID Cache
584 interfaces and added `name' argument. ID Cache does not handle
585 anymore the binary data only a names associated with given ID.
587 * When hashing a Client ID with silc_hash_id the entire ID is
588 not hashed anymore, instead only the hash of the Client ID is
589 hashed. This way we can access the Client ID from the cache
590 with Client ID but with the hash of the ID (which is a hash of
591 the nickname) as well without any difference in performance.
593 Added also silc_idcache_find_by_id_one_ext to do one on one
594 searching when we have the actual ID. Added also function
595 silc_hash_client_id_compare. The affected files are
596 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
598 * When hashing the name associated with a ID it is always done
599 in lowercase. This way we can access the cache without worrying
600 about case-sensitivity, even though, for example nicknames are
603 * Fixed a bug in server with channel message sending. It put
604 wrong ID type as destination ID. The affected file
607 * silc_idcache_del_by_context now deletes from all hash tables
608 by context. Affected file lib/silccore/idcache.c.
610 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Changed the client library to use the new ID Cache interface.
613 Changes around the source tree.
615 * Added silc_hash_table_rehash_ext to rehash with specific
616 hash function. Affected file lib/silcutil/silchashtable.[ch].
618 * Added silc_hash_string_compare to compare two strings in the
619 hash table. Affected file lib/silcutil/silcutil.[ch].
621 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Added new function silc_idcache_del_by_context into the
624 lib/silccore/idcache.[ch].
626 * Changed the server's ID list routines to use the new ID Cache
627 interface. Changes around the source tree.
629 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
631 * Added silc_hash_table_del[_by_context]_ext functions in to the
632 lib/silcutil/silchashtable.[ch].
634 Removed silc_hash_table_find_all* routines and added new
635 silc_hash_table_find_foreach to replace them.
637 Added silc_hash_table_replace_ext function as extended
638 replacing function. Separated the simple hash table interface
639 from the extended hash table interface in the file
640 lib/silcutil/silchashtable.h.
642 * Fixed minor bugs and changed it to use some of the new
643 hash table functions in lib/silccore/idcache.c
645 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
647 * Added new function silc_hash_table_find_all to return all keys
648 in the hash table by the specified key. As the hash table is
649 collision resistant it also makes it possible to have several
650 duplicate keys in the hash table. This function may be used to
651 find all of the keys from the hash.
653 Added user_context arguments to the SilcHashFunction,
654 SilcHashCompare and SilcHashDestructor to deliver user specified
657 Added new fuctions silc_hash_table_find[_all]_ext to do
658 extended lookup with specified hash and compare functions and
659 specified user contexts.
661 Added new function silc_hash_table_add_ext to add the key
662 with specified hash function and user context.
664 Added new function silc_hash_table_foreach to traverse all
665 entrys in the hash table. Added SilcHashForeach callback
668 Added new function silc_hash_table_del_by_context to delete
669 the entry only if the context associated with the key matches.
671 Affected files are lib/silcutil/silchashtable.[ch].
673 * Removed silc_hash_[server/client/channel]_id and added just
674 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
675 silc_hash_id_compare to compare two ID's using as the hash table
676 comparison function. Added also silc_hash_data to hash
677 binary data and silc_hash_data_compare to compare it.
679 * Removed silc_idlist_find_client_by_hash as it is not needed
680 anymore. Affected file silcd/idlist.[ch].
682 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
683 to use internally the SilcHashTable. The new ID Cache is a lot
684 faster than the old one. Some of the ID Cache interface was also
685 rewritten and obsolete and stupid functions were removed.
687 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Added entry_count field to the SilcHashTable to keep the number
690 of the entries in the table. Implemented the function
691 silc_hash_table_rehash. Added new function
692 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
694 Fixed a minor bug in silc_hash_table_free.
696 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
697 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
698 into the lib/silcutil/silcutil.[ch].
700 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Implemented a collision resistant hash table into the
703 lib/silcutil/silchashtable[ch]. See the header and the source
704 for the SilcHashTable API.
706 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Merged dotconf version 1.0.2 into lib/dotconf.
710 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Do not compile anything in lib/silcsim/* if the SIM support
713 is not enabled. The tree should now compile without problems
716 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
718 * Compiled the SILC under cygwin. Compiled and tested briefly
719 without problems. More tests needed. The SIMs didn't compile
722 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
724 * Fixed possible crash in silc_get_username in the
725 lib/silcutil/silcutil.c.
727 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Fixed a va_arg in silc/client_ops.c.
731 * Oops, RC5 routines were named AES and caused some problems
732 when not using SIM's. Affected file lib/silccrypt/rc5.c.
734 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Added new SilcIDIP structure into the lib/silccore/id.h and
737 replaced the old `ip' fields from all SILC ID's to that type.
738 This is a step towards IPv6 support.
740 The silc_id_get_len takes now the ID as an extra argument.
741 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
742 both IPv4 and IPv6 based ID's.
744 The affected files are lib/silccore/id.[ch] and other files
745 around the tree using these routines.
747 * Removed the ID length arguments in server from various
748 silc_server_send_notify_* routines -> they are not needed
751 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
753 * Fixed memory leak in silc_encode_pem_file in the file
754 lib/silcutil/silcutil.c.
756 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Check minor version as well in the SKE. Affected files are
759 silcd/protocol.c and lib/silcclient/protocol.c.
761 * Added --identifier option to the server so that an identifier
762 can be when creating the public key for the server. Affected
763 file is silcd/silcd.c.
765 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
766 lib/silccrypt/silcpkcs.c.
768 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Register default ciphers and stuff when using -C option with
771 the server. Affected file sildc/silcd.c.
773 * Put back the servers public key filename format, it is better
774 than the new one. For now, the client keys are saved with the
775 new filename format. The affected file silc/client_ops.c.
777 * Implemented the Cipher API for the rest of the ciphers that
778 did not implement it or implemented it the wrong way.
780 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
782 * Register default ciphers and stuff when using the -S option
783 in the client. Affected file silc/silc.c. Same also when
784 creating new key pair with -C option.
786 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Fixed the silc_verify_public_key client operation function to
789 save the public keys differently. The fingerprint is now
790 used as filename and not the hostname. This way also the
791 client keys are saved uniquely and not with hostnames. The
792 affected file is silc/client_ops.c.
794 * Trimmed the silc_hash_fingerprint function to remove extra
795 whitespaces from the end of the fingerprint. The affected
796 file is lib/silccrypt/silchash.c.
800 * Added silc_cipher_register_default function to register all
801 default ciphers. It can be used when configuration files
802 does not exist and the application does not want any specific
803 ciphers in any specific order.
805 The SilcDList is now used as silc_cipher_list dynamically
806 allocated cipher list. Removed the static list all together
807 and now all ciphers must be allocated to the dynamic list.
808 The silc_cipher_alloc routine was changed to check only the
811 All silc_cipher_* routines that used to return int returns
814 The affected files lib/silccrypt/silccrypt.[ch].
816 * The same thing was done to silc_hash_* as for silc_cipher_*
817 routines. Affected files lib/silccrypt/silchash.[ch].
819 * The same thing was done to silc_pkcs_* as for silc_cipher_*
820 routines. Affected files lib/silccrypt/silcpkcs.[ch].
821 Added also silc_pkcs_[un]register[_default] functions.
822 Removed the data_context from the PKCS API.
824 * Added silc_hmac_register_default function to register default
825 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
826 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
827 to unregister all hmacs at once.
829 * Register the default ciphers, hash functions, PKCSs and HMACs
830 if client's configuration file does not exist. The affected
833 * The client did not load the hash functions from the SIM
834 modules at all. Added support for this. Affected file is
837 * When decoding public key with silc_pkcs_public_key_decode, check
838 the supported algorithm only if PKCS are registered. Affected
839 file lib/silccrypt/silcpkcs.c. The same was done with the
840 silc_pkcs_private_key_decode.
842 * Fixed the SILC List routines to keep the list always in order.
843 It used to change the list's order when traversing the list but
844 not it preserves the order. Affected file lib/trq/silclist.h.
846 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Added the client library to use the SilcSocketConnection's
849 reference counter (by silc_socket_dup) to prevent the bug that
850 the socket object may be freed underneath async operation.
852 * The name resolv library checking fixes in the configure.in.pre.
855 * Created new version of the protocol drafts for future
856 development. The -03 drafts are the ones that will be changed
857 in the trunk now and the -02 will remain as they are.
859 * Send list of CUMODE notifys to the router when announcing
860 the channel users to the router. Affected file silcd/server.c.
861 If the router receiving channel founder CUMODE for a channel
862 that already has channel founder it will send CUMODE notify
863 to the sender to remove the channel founder rights from the
864 announced client. Affected file silcd/packet_receive.c.
866 * The CUMODE notify may now use Server ID as well as the entity
867 who changes the mode. Updated protocool specs.
869 * Updated INSTALL and README files.
871 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
873 * New web pages in the http://silc.pspt.fi. The pages was
878 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
880 * Implemented the [DenyConnectin] config section in the server.
881 Added silc_server_config_denied_conn to check whether incoming
882 connection is denied. Affected file silcd/serverconfig.[ch].
884 * Do not check the ports when checking the incoming configuration
885 data if the port is 0, meaning any. Affected file is
886 silcd/serverconfig.c.
888 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Fixed buffer overflow in silc_string_compare in the file
891 lib/silcutil/silcutil.c.
893 * Fixed double free in silc_server_command_leave in the file
896 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Fixed the version checking in the server. Affected file is
901 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
903 * Fixed the configuration data fetching when accepting new
904 connections in the server. Affected file silcd/server.c.
906 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Added `sender_entry' argument to the function
909 silc_server_packet_relay_to_channel so that we can check
910 whether some destination actually belongs to the same route
911 the sender belongs (ie, we must not resend the packet to the
912 sender). Affected file silcd/packet_send.[ch].
914 * Added `servername' field to the SilcClientEntry in the server
915 to hold the name of the server where client is from. Affected
916 file is silcd/idlist.h.
918 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * Moved the channel message encrypting in the router betwen
921 router connections from silc_server_channel_message to the
922 silc_server_packet_relay_to_channel since we want to check
923 whether we have anybody channel before encrypting anything.
924 Affected files silcd/packet_[receive/send].c.
926 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Fixed the [AdminConnection] server config section to support
929 multiple entries. Affected file silcd/serverconfig.c.
931 * Added support into the server to check the validity of the
932 incoming connection before executing any KE or authentication
935 * The connection configuration is now saved to the KE and
936 connection auth protocol contexts and not fetched anymore in
937 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
939 * The local hosts listenning address and port is also resolved
940 now when starting the server. We want to have the socket object
941 to include the real address and port for the listener. Added
942 new function silc_net_check_local_by_sock into the files
943 lib/silcutil/silcnet.[ch].
945 * Fixed a broadcast bug in server -> do not broadcast if we
948 * Fixed a routing bug. Do not route broadcast packets ever.
949 Broadcast packets must be processed always and not routed since
950 they may be destined to some other host than yourself and thus
951 would get routed without no good reason. Affected file is
954 * Added function silc_server_config_is_primary_route to check
955 whether primary router connection has been configured (a router
956 configuration that we are initiating). If there is not, we
957 will assume that there is only two routers in the SILC network
958 and we will use the incoming router connection as our primary
959 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
961 * Changed the order of the broadcasting. Broadcast _after_ the
962 packet has been processed not before. Affected file is
965 * Fixed a [ClientConnection] parsing bug. The port was never
966 parsed correctly thus resulting to port 0. Affected file
967 silcd/serverconfig.c.
969 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
970 argument and did not set the broadcast packet flag. Affected
971 file silcd/packet_send.c. Fixed same bug in the function
972 silc_server_send_notify as well.
974 * If we receive NEW_ID packet for our own ID in the server, ignore
977 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Removed the nickname from the Private Message Payload.
982 Updated the code and the protocol specs.
984 * Updated protocol specs for submitting to the IETF.
986 * Tweaked the Random Number Generator a bit. Affected file
987 lib/silccrypt/silcrng.c. Exported a new function
988 silc_rng_[global]_add_noise which can be used to add more
991 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Do not parse packets with different timeout when protocol
994 is active -> may cause problem with rekey. Affected file
997 * When server receives signoff notify it must not create
998 new channel key if the client is on any channels since the
999 sender of the signoff notify will create it.
1001 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Added printing of error messages during SKE protocol from the
1004 failure packet sent by server during SKE. Affected file
1007 * Removed the client's failure_callback handling with timeout
1008 and handle it immediately when received.
1010 * The SKE library returned wrong type in SUCCESS and FAILURE
1011 packets. They must be 32 bit MSB not 16 bit MSB.
1013 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Ok, rewrote the logic of the re-key and now it seems to work.
1016 I tested it on high traffic with frequent re-keys without
1017 problems. Added hmac_receive (and renamed hmac to hmac_send)
1018 in SilcClientConnection in lib/silcclient/client.h and
1019 in SilcIDListData in silcd/idlist.h. Also, removed the
1020 SilcPacketParserContext's cipher and hmac fields as they are
1021 not needed anymore and actually caused some problems when
1022 the ciphers and hmac's changed underneath the packet parser.
1024 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * If re-key protocol is active then process the incoming packets
1027 synchronously since we must assure that icoming packets encrypted
1028 with the old key is processed before the new keys is set to
1029 use. This is true other packets than for REKEY packets.
1030 Affected file silcd/server.c. The same was done to client library
1031 as well, affected file lib/silcclient/client.c.
1033 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Fixed bug in client and server to accept the force send if
1036 the packet is send from silc_[server/client]_packet_process
1037 function. Otherwise the packets are never delivered, oops.
1039 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1041 * Disable force sending of packets when REKEY protocol is active.
1042 We must assure that no packet is sent directly when rekey is
1043 performed. All packets must be sent through packet queue.
1044 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1045 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1046 function is silc_[server/client]_packet_send_real to check
1049 * Replaced the SIM paths from example config files to
1050 /usr/local/modules. Also, make install creates now
1051 /usr/local/silc/logs directory to hold all the SILC server
1054 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1056 * Made the configure.in.pre work on Solaris. Patch by salo.
1058 * Made all ciphers compatible with non-x86 machines. Defined
1059 CBC mode macros into lib/silccrypt/ciphers_def.h.
1061 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1063 * Fixed the make install.
1065 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * When MAC computation fails the silc_packet_decrypt returned 0
1068 even though it was supposed to return -1. Fixed this. The
1069 affected file is lib/silccore/silcpacket.c.
1071 * Do not replace the config files in /etc/silc (in make install)
1072 if they already exist. Affected file ./Makefile.am.
1074 * Do not send re-key packets immediately but through packet queue.
1075 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1077 * Changed silc_net_check_host_by_sock to return FALSE if the
1078 IP/DNS could not be resolved. Though, it returns the IP address
1079 now even if it could not resolve it (but returns also FALSE).
1080 Affected file lib/silcutil/silcnet.[ch].
1082 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1084 * Added silc_pkcs_decode_identifier to decode the public key's
1085 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1086 Added also silc_pkcs_free_identifier. Added also new context
1087 SilcPublicKeyIdentifier.
1089 * Added -S option to the silc client. It is used to dump the
1090 contents of the specified public key file.
1092 * Changed the PKCS api to return the public key length when
1093 setting the public key.
1095 * Fixed a fatal bug in the public and private key file loading.
1096 Affected file lib/silccrypt/silcpkcs.c.
1098 * Execute the packet parsing for client with zero (0) timeout
1099 if the protocol is active. Affected file silcd/server.c.
1101 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1103 * Made the key generation options to the silcd program. Added
1104 -C option, equivalent to client's option.
1106 * Added new [ServerKeys] config section to the server. It
1107 configures the server's public and private key.
1109 * Defined generic Public Key Payload into the protocol
1110 specification to send specific type of public keys and
1113 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1114 public key or certificate.
1116 * Implemented the GETKEY command to the server and to the
1117 client library and on user interface.
1119 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Made preliminary `make install' work.
1123 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Added SilcServerRekey context into silcd/idlist.h.
1127 * Added the PFS support as defined in the specification to the
1128 SKE protocol. Affected files lib/silcske/*.c.
1130 * Added `ske_group' field to the SilcServerRekey context to hold
1131 the number of the SKE group that is used with PFS in re-key.
1132 Affected file silcd/idlist.h.
1134 * Added PFS re-key support to the server. Affected file is
1137 * Added silc_protocol_cancel to cancel execution of the next
1138 state of the protocol. Affected file is
1139 lib/silccore/silcprotocol.[ch].
1141 * Added the re-key support with and without PFS to the client
1142 library. Re-key is performed once in an hour, by default.
1144 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1145 Added silc_client_rekey_callback and silc_client_rekey_final.
1146 Affected files are lib/silcclient/protocol.[ch] and
1147 lib/silcclient/client.[ch].
1149 * Removed the `hmac_key' and `hmac_key_len' fields from the
1150 SilcClientConnection structure; not needed. Affected file is
1151 lib/silcclient/client.h.
1155 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Do not ask whether user wants to use the negotiated private key
1158 for private messages, just use it. Affected file is
1159 silc/local_command.c.
1161 * Added `send_enc_key' and `enc_key_len' fields to the
1162 SilcIDListData structure since they are needed in the re-key
1163 phase. Affected file is silcd/idlist.[ch].
1165 * Implemented the simple re-key protocol into the server.
1166 Affected files silcd/server.c and silcd/protocol.[ch]. The
1167 re-key will be performed once in an hour, by default.
1169 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1170 Added silc_server_rekey, silc_server_rekey_callback and
1171 silc_server_rekey_final.
1173 * Removed Tunneled flag from the protocol. Updated the code
1174 and the specifications.
1176 * Adde `pfs' field to the SilcIDListData to indicate whether
1177 the PFS is to be performed in the re-key. Affected file is
1180 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1183 int64 of at least the xintXX size. If void * is less that 4
1184 bytes uint32 * will be used. Defined bool as boolean.
1186 * Changed _ALL_ unsigned long and unsigned int to uint32,
1187 unsgined short to uint16 in the source tree.
1189 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1190 not handle clients that has entry->data.registered == FALSE.
1191 They are not in the network anymore. Affected file is
1194 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Implemented the sending of the SERVER_SIGNOFF notify in the
1197 server. Affected file is silcd/server.c.
1199 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1200 Added also silc_notify_payload_encode_args into the
1201 lib/silccore/silcnotify.[ch].
1203 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1204 Affected file silcd/packet_receive.c.
1206 * Implemented the SERVER_SIGNOFF notify handling in the client
1207 library. Affected file lib/silcclient/client_notify.c. Also,
1208 implemnted the printing of the SERVER_SIGNOFF info to the
1209 application. Affected file silc/client_ops.c.
1211 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1212 if the deleting was successful. Affected file silcd/idlist.[ch].
1214 * Added support for public key authentication in the connection
1215 authentication protocol in the client library. Affected file
1216 lib/silcclient/protocol.c.
1218 * Changed the server's silc_idlist_get_clients_by_* interface
1219 to support already allocated array so that new entries may be
1220 added to pre-allocated array. Affected file silcd/idlist.[ch].
1221 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1222 and command replies.
1224 * All command reply functions in the server now calls the
1225 pending command callback even if error occured. This way the
1226 error will be delivered to the client as well. Affected files
1227 silcd/command.c and silcd/command_reply.c.
1229 * Fixed INFO command to return local server's info if no server
1230 was provided. Affected file lib/silcclient/command.c.
1232 * Removed RESTART command for good. Updated the code and the
1235 * Rewrote parts of the task system. It is a bit simpler now.
1236 Removed unsued task priorities. The affected files are
1237 lib/silcutil/silctask.[ch].
1239 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Moved the USERS printing from the library to the application.
1242 Affected files lib/silcclient/command.c and silc/client_ops.c.
1244 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Added channel key re-key support. The re-key is perfomed
1249 only by the router and is done once in an hour. Added `rekey'
1250 field to the SilcChannelEntry in the server. Affected files
1251 silcd/server.c and silcd/idlist.h.
1253 * Added silc_task_unregister_by_context into the file
1254 lib/silcutil/silctask.[ch].
1256 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1258 * Added SILC_UMODE_GONE mode to indicate when the client is not
1259 present in the SILC network. Added also support to the local
1260 command AWAY that will set this mode. Added support of showing
1261 "xxx is gone" in WHOIS command. The USERS command shows the
1262 gone status as well.
1264 * Fixed setting server and router operator privileges in the
1265 server's UMODE command. Affected file silcd/command.c.
1267 * Merged the SKE KE1 and KE2 payloads into one payload. The
1268 new KE payload is equivalent to the old KE2 payload.
1270 Cleaned up the SKE Start Payload parsing. It now uses the
1271 simple buffer unformatting to do the parsing. A lot faster
1274 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1275 to the SKE that is used to indicate whether both of the SKE
1276 parties should perform authentication. By default only the
1277 responder performs authentication. By setting this flag also
1278 the initiator must do authentication. By default it is unset
1279 since in normal SKE case, client to server connection, only
1280 the responder should do authentication. When doing SKE between
1281 two clients both should perform authentication. Updated the
1282 code and the protocol specs.
1284 * A little fix to IDENTIFY command in the server. Search the
1285 client first by hash not nickname. Affected file is
1288 * Fixed the silc_client_close_connection to support closing
1289 the client to client connections wihtout deleting too much
1290 data. Affected file lib/silcclient/client.c.
1292 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1293 are received if protocol used to be active but is not anymore
1294 the application would crash due to NULL pointer dereference.
1295 Affected files silcd/server.c and lib/silcclient/client.c.
1297 * Added `hash' field to the SilcClientConnection to include
1298 the hash function negotiated in the SKE protocol.
1300 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1301 to set the channel founder authentication data. A client can
1302 claim the founder rights later by providing the authentication
1303 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1304 This way the channel founder can regain the channel founder
1305 privileges even it is left the channel. This works only on
1306 local server and the client must be connected to the same
1307 server to be able to regain the founder rights. Updated the
1308 protocol specs accordingly.
1310 Added support to the CMODE command in the client to set the
1311 founder auth data. Read the README to see how to set it.
1313 Added support to the CUMODE command to claim the founder
1314 rights. Read the README to see how to do it.
1316 Added support for the founder authentication to the Channel
1317 Entry in the server. Affected file silcd/idlist.h.
1319 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1320 server's CMODE command. Affected file silcd/command.c.
1322 * Added the following new functions into lib/silccore/silcauth.[ch]:
1323 silc_auth_get_method and silc_auth_get_data.
1325 * The server now saves the remote hosts public key to the
1326 SilcIDListData pointer. Affected file silcd/protocol.c.
1328 * The normal server now does not remove the channel entry from
1329 the cache if the founder authentication data is set. It used
1330 to remove it if the founder was the last one on the channel on
1331 the server and left the channel. The auth data is saved and
1332 if the channel is re-joined later the old entry is used with
1333 the old auth data. Affected files silcd/command_reply.c and
1336 * Removed the `pkcs' field from the SilcIDListData structure
1337 in the server; it is not used. Affected file silcd/idlist.h.
1339 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Fixed packet processing on slow links. Partial packets were
1342 never re-processed because the incoming data buffer was cleared
1343 by the application. Application must not directly clear the
1344 sock->inbuf, the packet processing routines handle it. Fixed
1345 this in client library and in server.
1347 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Fixed the WHOIS and IDENTIFY send reply function to really
1350 check whether to send list or just one entry. Affected file
1353 * Cleaned up the LEAVE command's channel key distribution. The
1354 affected file silcd/command.c.
1356 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1357 can enforce the channel mode as well. In that case the ID
1358 includes the ID of the server. The code now enforces the
1359 mode change if the router have different mode than the server.
1361 * The notify client operation with CMODE_CHANGE notify can now
1362 return NULL client_entry pointer if the CMODE was not changed
1363 by client. Application must check for this.
1365 * Added <Server ID> argument to INFO command to support server
1366 info fetching by Server ID.
1368 * Added silc_server_announce_get_channel_users to get assembled
1369 packets of channel users of the specified channel. Affected
1370 file silcd/server.[ch].
1372 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1373 was freed underneath the ID Cache.
1375 * Re-announce clients when the server received CHANNEL_CHANGE
1376 notify from the router. Affected file silcd/packet_send.c.
1378 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1381 crashed since it did not handle the fact that there is no cipher
1382 called "3" and didn't check the error condition. Now fixed.
1384 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1385 flag. It can be used to send message requests.
1387 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Implemented the RESTART command in the client.
1391 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1392 notice type messages. Added notice printing to the user
1395 * The channel keys are not re-generated if the channel's mode
1396 is PRIVKEY, ie private key on the channel exists. Affected
1397 files silcd/server.c and silcd/command.c.
1399 * Fixed a little bug in channel message delivery when channel
1400 private keys are set in the server. Affected file is
1401 silcd/packet_send.c.
1403 * Changed the setting on channel->on_channel = TRUE from the
1404 silc_client_save_channel_key to the JOIN command reply. The
1405 key payload is not received if the private channel key is set.
1406 Affected file lib/silcclient/command_reply.c and the
1407 lib/silcclient/client_channel.c.
1409 * When the CMODE_CHANGE notify is sent and the channel private
1410 key mode is removed the channel key must be re-generated in
1411 other cells as well. Added this support for the router in the
1412 silcd/packet_receive.c.
1414 * Added new local command NOTICE to send notice message on
1415 channel. Affected file silc/local_command.[ch].
1417 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Added new local command ME to the client. It is used to send
1420 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1421 some action. Affected file silc/local_command.[ch].
1423 * Changed channel_message and private_message client operations
1424 to deliver the message flags to the application. Added also
1425 the `flags' arguments to the silc_client_send_channel_message
1426 and silc_client_send_private_message functions. Affected file
1429 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1431 * Redefined the Private Message Payload to support private message
1432 keys and to support the new private message flags. Updated
1433 the protocol specs. Flags makes it possible to have for example
1434 CTCP style messages.
1436 * Added new type SilcPrivateMessagePayload and defined an API
1437 for it in the lib/silcclient/silcprivate.[ch].
1439 * Tested private message private keys successfully. Tested the
1440 private message key set, unset and list commands with the new
1443 * Redefined the Channel Message Payload to include the channel
1444 message flags (equal with private message flags) to support
1445 for example CTCP style messages.
1447 * Defined some of the message (for channel and private message)
1448 flags. Updated the protocol specs and added the flags to the
1449 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1451 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1453 * Added SilcKeyAgreementStatus type to the key agreement routines
1454 to indicate the current status and error if one occured.
1455 The status types are defined in the lib/silcclient/silcapi.h.
1457 * Added new local command KEY that is used to set and unset private
1458 keys for channels, set and unset private keys for private messages
1459 with remote clients and to send key agreement requests and
1460 negotiate the key agreement protocol with remote client. The
1461 key agreement is supported only to negotiate private message keys,
1462 it currently cannot be used to negotiate private keys for channels,
1463 as it is not convenient for that purpose.
1465 * Fixed a minor pending callback setting bug in the function
1466 silc_client_get_client_by_id_resolve, now the function works.
1467 Affected file lib/silcclient/idlist.c.
1469 * Added function silc_net_get_local_port to get local bound
1470 port by socket. Added to lib/silcutil/silcnet.[ch].
1472 * Added `sockets' and `sockets_count' fields to the SilcClient
1473 object. They hold the sockets of the listenning sockets in
1474 the client. Listenning sockets may be for example the key
1475 agreement server. Affected file lib/silcclient/client.[ch].
1476 Added functions the silc_client_add_socket and the
1477 silc_client_del_socket. They are exported to the application
1480 * Added ~./silc/clientkeys to support other client's public keys.
1482 * Renamed verify_server_key client operation to verify_public_key
1483 and added one argument to indicate the type of the connection
1484 (server, client etc.).
1486 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Added silc_server_connection_auth_request to handle the
1489 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1490 silcd/packet_receive.[ch].
1492 * Added silc_server_send_connection_auth_request into the
1493 silcd/packet_send.c to send the connection auth request packet.
1495 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1498 * Fixed the public key authentication in responder side in the
1499 server. The `auth_data' pointer includes the SilcPublicKey
1500 not the path to the public key. Affected file silcd/protocol.c.
1502 * Implemented the public key authentication in the initiator side
1503 in the server. Affected file silcd/protocol.c.
1505 * Removed the [RedirectClient] config section from the server
1506 configuration. Is not needed and I don't want to implement it.
1508 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1510 * Cleaned up the CMODE command in the server. It now works
1511 correctly and supports all the modes defined in the protocol.
1512 Affected file is silcd/command.c.
1514 * Added `hmac_name' field to the SilcChannelEntry in the server
1515 to hold the default HMAC of the channel. It can be set when
1516 creating the channel (with JOIN command). Affected files
1519 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1520 type to indicate the change of the current cipher and hmac
1521 on the channel. Client can safely ignore the <cipher> argument
1522 (if it chooses to do so) since the CHANNEL_KEY packet will
1523 force the channel key change anyway. The <hmac> argument is
1524 important since the client is responsible of setting the new
1525 HMAC and the hmac key into use.
1527 * Fixed the CMODE command in the client library as well.
1529 * Tested CMODE command in router environment successfully.
1531 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Show the version of the remote client (or server) when connecting
1534 to the server. It is logged to the log file. Affected file
1535 is silcd/protocol.c.
1537 * Fixed the KILLED notify handling in the client library. The
1538 client must be removed from all channels when receiving the
1541 Also, do not remove the client entry when giving the KILL
1542 command but when the KILLED notify is received.
1544 * Removed silc_idlist_find_client_by_nickname from the server.
1545 Not needed anymore. Affected files silcd/idlist.[ch].
1547 * Implemented the CHANNEL_CHANGE notify type handling to the
1548 server. Affected file silcd/server.c.
1552 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1554 * Added silc_server_send_notify_invite to send the INVITE
1555 notify between routers.
1557 * Implemented the INVITE command correctly to the server.
1559 * Implemented the INVITE notify type handling in the server.
1561 * Implemented the INVITE command to the client library and on the
1564 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Added function silc_server_get_client_resolve to find the
1567 client entry by ID from all ID lists and then resolve it
1568 (using WHOIS) if it cannot be found. Affected file is
1571 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Implemented the BAN command to the client library.
1575 * The JOIN command in the server now checks the invite list
1578 * Changed the silc_command_reply_payload_encode_va and the
1579 silc_command_payload_encode_va to support that if argument is
1580 NULL it ignores and checks the next argument. Affected file
1581 lib/silccore/silccommand.c.
1583 * Added silc_server_send_notify_ban to send the BAN notify
1584 type between routers.
1586 * Chaned the silc_notify_payload_encode to support that if
1587 argument is NULL it ignores and checks the next argument.
1588 Affected file lib/silccore/silcnotify.c.
1590 * Tested ban lists in router environment successfully.
1592 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Implemented BAN command to the server, in silcd/command.[ch].
1596 * Removed the BAN and INVITE_LIST modes from the CMODE command
1599 * Added function silc_string_match to regex match two strings.
1600 Affected files lib/silcutil/silcutil.[ch].
1602 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Redefined parts of the SilcChannelEntry in the server to support
1605 the new ban and invite lists.
1607 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Redefined the INVITE command. The same command can be used to
1610 invite individuals to the channel but also to manage the invite
1611 list of the channel (to add to and remove from the invite list).
1612 Updated the protocol specs.
1614 * Added new command SILC_COMMAND_BAN that can be used to manage
1615 the ban list of the channel. Updated the protocol specs.
1617 * Removed the channel modes: the SILC_CMODE_BAN and the
1618 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1619 in the CMODE command. The equivalent features are now available
1620 using INVITE and BAN commands. Updated the protocol specs.
1622 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1623 in the network about change in the current ban list. The notify
1624 type is not used by the client.
1626 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1627 support the invite lists.
1629 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Added new function silc_string_regexify that converts string
1632 including wildcard characters into regex string that can
1633 be used by the GNU regex library. Added into the file
1634 lib/silcutil/silcutil.[ch].
1636 Added silc_string_regex_combine to combine to regex strings
1637 into one so that they can be used as one regex string by
1638 the GNU regex library. Added into the file
1639 lib/silcutil/silcutil.[ch].
1641 Added silc_string_regex_match to match two strings. It returns
1642 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1644 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Imported GNU regex to the soruce tree into lib/contrib.
1647 Fixed some compiler warning from the regex.c.
1649 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Fixed MOTD command in the server to work in router environment.
1653 * Fixed the MOTD command in the client library to support
1654 the server argument in the command.
1656 * Added `nickname_len' argument to the silc_idlist_add_client
1657 in the server, as the `nickname' argument may be binary data
1660 * Added silc_idlist_get_channels to return all channels from
1663 * Implemented LIST command to the server. Affected file is
1666 * Implemented the LIST command to the client library and on the
1669 * Added [<user count>] argument to the LIST command reply.
1670 With private channels the user count is not shown.
1672 * Updated TODO and README.
1674 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * The client entry's data.registered must be TRUE even with
1677 global client entry on global client list. The data.registered
1678 is used to check whether the client is anymore in the network,
1679 for example with WHOWAS command so it must be valid.
1681 * Fixed the WHOWAS command in the server. It now actually works
1682 in router environment. Added function into silcd/command_reply.c
1683 silc_server_command_reply_whowas_save.
1685 * Added silc_idlist_purge function to the silcd/idlist.c
1686 to periodically purge the ID Cache.
1688 * Fixed INFO command in the server. It works now in router
1689 environment. Added <server name> argument to the INFO command
1690 reply. Updated the protocol specs.
1692 * Fixed minor bug in silc_idcache_purge to not purge if the
1693 expire value is zero.
1695 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1696 they were buggy because of the WHOWAS information.
1698 * Fixed local command MSG to handle the async resolving of
1699 the remote client properly. It used to fail the first MSG.
1700 Affected file silc/local_command.c.
1702 * Added `data_len' field to SilcIDCache context.
1704 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Update TODO. Todo in commands in the server.
1708 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1711 used by routers as broadcast packet to inform other routers
1712 about the changed user mode.
1714 Implemented the notify handling in the server. Affected file is
1715 silcd/packet_receive.c. Added the function
1716 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1718 * Added new generic Channel Payload and deprecated the New Channel
1719 Payload. The New Channel Payload is now the generic Channel
1722 * Added new argument `mode' to the silc_server_send_new_channel
1723 as it is required in the Channel Payload now.
1725 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1726 and created a new and real SilChannelPayload to represent the
1727 new generic Channel Payload. Implemented the encode/decode
1728 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1730 * Added silc_server_get_client_channel_list to return the list
1731 of channels the client has joined for WHOIS command reply.
1732 Affected file silcd/server.[ch].
1734 * Implemented the channel list sending in the WHOIS command reply
1735 in server and in the client.
1737 Implemented the channel list displaying on the user interface
1738 as well. Affected file silc/client_ops.c.
1740 * Added silc_channel_payload_parse_list to parse list of Channel
1741 Payloads. It returns SilcDList list of SilcChannelPayloads.
1742 Client for example can use this function to parse the list of
1743 channels it receives in the WHOIS command reply. The caller
1744 must free the list by calling silc_channel_payload_list_free.
1745 Affected files lib/silccore/silcchannel.[ch].
1747 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1749 * Added one new argument <user mode> to the WHOIS command reply
1750 to return the mode of the user in SILC. Updated the protocol
1753 Implemented it to the server and client.
1755 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1757 * Fixed the mode printing on the user interface on joining.
1758 Affected file silc/client_ops.c.
1760 * Implemented the UMODE command and user modes in general to the
1761 client library and to the user interface.
1763 * Implemented the UMODE command to the server.
1765 * The server now sends UNKNOWN_COMMAND error status if client sends
1766 unknown command. Affected file silcd/command.c.
1768 * All server commands now handle the command identifier the right
1769 way when sending the command reply to the client. The client can
1770 use to identify the command replies with the identifier.
1772 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1774 * Added silc_server_get_client_route to resolve the route to
1775 the client indicated by the client ID. Affected file is
1778 * Added silc_server_relay_packet as general function to relay
1779 packet to arbitrary destination. This deprecates functions
1780 like _send_private_message_key, _relay_notify etc. Affected
1781 file is silcd/packet_send.[ch].
1783 Removed silc_server_send_key_agreement,
1784 silc_server_send_private_message_key and
1785 silc_server_packet_relay_notify functions from the file
1786 silcd/packet_send.[ch].
1790 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1791 server. Affected file silcd/packet_receive.[ch].
1793 * Implemented the KILL command to the client. Implemented the
1794 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1795 Affected files lib/silcclient/command[_reply].c and
1796 lib/silcclient/client_notify.c. Implemented the KILL notify
1797 printing in the user inteface.
1799 * Fixed a lot silc_parse_nick memory leaks from the client
1800 library in the file lib/silcclient/command.c.
1802 * Changed the silc_server_send_notify_on_channels's `sender'
1803 argument from SilcSocketConnection to SilcClientEntry to
1804 check the sender as entry and not as connection object and not
1805 to send to the client provided as argument. The affected file
1806 is silcd/packet_send.[ch].
1808 * The notify packets that are destined directly to the client used
1809 to not to be processed by the server. Now changed that and the
1810 server processes all notify packets. After relaying the packet
1811 to the client the notify packet is processed in the server.
1813 * The silc_server_free_client_data now checks whether there is
1814 pending outgoing traffic for the client and purges the data to
1815 the network before removing the client entry.
1817 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1820 an client is killed from the SILC Network. Updated the protocol
1823 Added new function silc_server_send_notify_killed to the
1824 silcd/packet_send.[ch].
1826 * Added function silc_server_packet_relay_notify to relay notify
1827 packets that are destined directly to a client. In this case
1828 the server does not process the notify packets but merely relays
1829 it to the client. Affected file silcd/packet_send.[ch].
1831 Added also silc_server_packet_process_relay_notify to check
1832 whereto relay the notify. Affected file is
1833 silcd/packet_receive.[ch].
1835 * Implemented the KILL command to the server.
1839 * Added the backup schema desgined last fall to the protocol
1840 specs for everyone to see. The specification is in the
1841 *-spec-xx.txt draft and the packet type definitions for the
1842 backup routers is in *-pp-xx.txt draft. Thusly, added also
1843 new packet type SILC_PACKET_CELL_ROUTERS.
1845 * A big security problem in the implementation discovered. The
1846 signoff of an client did not cause new channel key generation
1847 which it of course should've done. The channel keys must be
1848 always re-generated when client leaves (or signoffs) the channel.
1849 The silc_server_remove_from_channels funtion now handles
1850 the channel key re-generation.
1852 * Added `sender' argument to the silc_server_send_notify_on_channels
1853 to not to send the client provided as argument. Affected file
1854 silcd/packet_send.[ch].
1856 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Implemented OPER and SILCOPER commands into the server and
1861 * Added silc_auth_verify and silc_auth_verify_data to verify
1862 the authentication directly from the authentication payload.
1863 It supports verifying both passphrase and public key based
1864 authentication. Affected file lib/silccore/silcauth.[ch].
1866 * Added `hash' field to the SilcIDListData structure. It is the
1867 hash negotiated in the SKE protocol. Affected file is
1870 * Slight redesigning of the SilcAuthPayload handling routines.
1871 Do not send SilcPKCS but SilcPublicKey as argument.
1873 * Implemented the public key authentication support to the
1874 serverconfig. The public key is loaded from the provided path
1875 and saved as authentication data to void * pointer. Thus,
1876 changed the unsigned char *auth_data to void *auth_data;
1878 * Fixed SHUTDOWN command to send the reply before the server
1879 is shutdown. :) Affected file silcd/command.c.
1881 * Fixed fatal bug in CONNECT command. The hostname was invalid
1882 memory and server crashed. Affected file silcd/command.c.
1884 * Fixed fatal bug in CLOSE command. The server_entry became
1885 invalid but was referenced later in the command. Affected file
1888 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Fixed fatal bug in failure packet handling. Server ignored
1891 the failure and thus crashed when it came.
1895 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1898 that the command may be executed only once in (about) 2 seconds.
1899 The old SILC_CF_LAG flag is same but allows command bursts up
1900 to five before limiting.
1902 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1903 server code. Various commands now includes the CF_LAG_STRICT
1904 flag to disallow any kind of miss-use of the command.
1906 * Fixed the silc_buffer_unformat to not to allocate any data
1907 if the length of the data is zero. It used to allocate the
1908 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1910 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Changed the format of AdminConnection configuration section
1913 in the server. Added username of the admin to the format.
1914 Affected files silcd/serverconfig.[ch].
1916 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1917 to return admin configuration data by host, username and/or
1920 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Implemented WHOWAS command to the server. Added the functions:
1924 silc_server_command_whowas_parse,
1925 silc_server_command_whowas_send_reply,
1926 silc_server_command_whowas_from_client and
1927 silc_server_command_whowas_from_server
1929 * Added <Client ID> argument to the WHOWAS command reply. Updated
1930 the protocol specs accordingly.
1932 * Implemented WHOWAS command and command_reply to the client
1935 Implemented the WHOWAS printing on the user interface.
1937 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Added new argument to the WHOWAS command reply, the real name.
1940 It is an optional argument. Updated the protocol specs.
1942 * Added SilcIDCacheDestructor callback that is registered when
1943 the SilcIDCache is allocated. The callback is called when
1944 an cache entry in the ID Cache expires, or is purged from the
1945 cache. Added into lib/silccore/idcache.[ch].
1947 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1948 to destruct the client entries when the cache entry expires.
1949 Other ID Cache's in server and in the client library ignores
1952 * If the ID Cache entry's `expire' field is zero then the entry
1953 never expires. Added boolean `expire' argument to the
1954 silc_idcache_add function in the lib/silccore/idcache.[ch].
1955 If it is TRUE the default expiry value is used.
1957 * Added silc_server_free_client_data_timeout that is registered
1958 when client disconnects. By default for 5 minutes we preserve
1959 the client entry for history - for WHOWAS command.
1961 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added support to the server to enforce that commands are not
1964 executed more than once in 2 seconds. If server receives
1965 commands from client more frequently, timeout is registered
1966 to process the commands. Affected file silcd/command.c.
1967 Added new function silc_server_command_process_timeout.
1969 * Changed NICK_NOTIFY handling in client library to check that
1970 if the client's nickname was changed, so there is no need to
1971 resolve anything from the server.
1973 * Removed error printing from the WHOIS and IDENTIFY commands.
1974 If error occurs then it is ignored silently in the client library.
1975 The application, however, may map the received error to
1976 human readable error string. The application currently maps
1977 the NO_SUCH_NICKNAME error to string.
1979 * Made the command status message public to the application. Moved
1980 them from lib/silcclient/command_reply.c to
1981 lib/silcclient/command_reply.h. The application can map the
1982 received command status to the string with the
1983 silc_client_command_status_message function.
1985 * Added check to the server to check that client's ID is same
1986 as the Source ID in the packet the client sent. They must
1989 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Added dist-bzip hook to the Makefile.am to make bzip2
1992 compressed distributions.
1994 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Server now enforces the maximum length for the nickname and
1997 the channel as protocol specification dictates. 128 bytes for
1998 nickname and 256 bytes for channel name.
2000 * Moved the WHOIS printing to the application. The client libary
2001 does not print out the WHOIS information anymore, the application
2002 must do it. Renamed silc_client_command_reply_whois_print to
2003 the silc_client_command_reply_whois_save.
2005 The client's idle time is also sent to the application now, and
2006 the idle is shown on screen.
2008 * Added silc_client_command_reply_identify_save to save the
2009 received IDENTIFY entries.
2011 * Do not check for channel private keys in message sending and
2012 reception if the channel does not have the PRIVKEY mode set.
2013 Affected file lib/silclient/client_channel.c.
2015 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2018 just surfaced after chaning the JOIN procedure.
2020 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Added silc_client_get_clients_by_list to get client entries
2023 from Client ID list, that is returned for example by JOIN
2024 and USERS command replies. The application should use this
2025 function for example when JOIN command reply is received to
2026 resolve the clients already on the channel (library does not
2027 do that anymore as USERS command reply is not used in the JOIN
2028 procedure anymore). Affected files lib/silcclient/silcapi.h and
2029 lib/silcclient/idlist.c.
2031 * JOIN command reply and USERS command reply returns now SilcBuffer
2032 pointers instead of unsigned char pointers when returning
2033 the client list and mode list.
2035 * Added <Client ID> argument to the JOIN command reply, mainly
2036 for the server to identify for which client the command was
2037 originally sent. Updated protocol specs accordingly.
2039 * Added SilcDlist private_key pointer to the SilcChannelEntry
2040 in the client to support the channel private keys. Affected
2041 file is lib/silcclient/idlist.h.
2043 * Added SilcChannelPrivateKey argument to the function
2044 silc_client_send_channel_message so that application can choose
2045 to use specific private ke if it wants to. If it is not provided,
2046 the normal channel key is used, unless private keys are set.
2047 In this case the first (key that was added first) is used
2048 as the encryption key.
2050 * Implemented the support for channel private key handling.
2051 Implemented the following functions:
2053 silc_client_add_channel_private_key,
2054 silc_client_del_channel_private_keys,
2055 silc_client_del_channel_private_key,
2056 silc_client_list_channel_private_keys and
2057 silc_client_free_channel_private_keys
2059 Affected file lib/silcclient/client_channel.c.
2061 * Added the support for the private keys in the channel message
2062 sending and encryption and in the message reception and
2063 decryption. Affected funtions are
2064 silc_client_send_channel_message and silc_client_channel_message.
2066 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2068 * Added SKE's key verify callback to the client library's
2069 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2071 * Removed the statement that server (or router) must send USERS
2072 command reply when joining to the channel so that the client
2073 knows who are on the channel. Instead, the client list and
2074 client's mode list is now sent in the JOIN command reply to the
2075 client who joined channel. This is better solution.
2077 * Added function silc_server_get_users_on_channel and function
2078 silc_server_save_users_on_channel to the silcd/server.[ch].
2080 * Removed function silc_server_command_send_users from the
2083 * Do not show topic on the client library anymore. The topic is
2084 sent in the command reply notify to the application and the
2085 application must show the topic now.
2087 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2089 * Added client searching by nickname hash into the IDENTIFY and
2090 WHOIS commands in the server as they were clearly missing from
2091 them. Affected file is silcd/command.c.
2093 * Fixed a bug in private message receiving in the client library.
2094 The remote ID was freed and it wasn't supposed, now it is
2097 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Minor fix to the channel payload; allocate the data area, as it
2100 needs to be of specific length.
2102 * If the key agreement port is zero then the operating
2103 system will define the bound port. Affected files are
2104 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2106 * Added new function silc_channel_payload_decrypt into the file
2107 lib/silccore/silcchannel.[ch].
2109 * Moved the channel message etc, check from silc_packet_decrypt
2110 to applications. The library calls now a generic
2111 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2112 when the packet is either normal or special. This was done to
2113 allow more wide range of checking that was not allowed when
2114 the code was in library. Now applications can do virtually any
2115 checks to the packet and return to the library the decision how
2116 the packet should be processed. Affected files are
2117 lib/silccore/silcpacket.[ch].
2119 Added silc_server_packet_decrypt_check to the server and
2120 silc_client_packet_decrypt_check to the client library.
2122 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2123 to send with specified source and destination information.
2125 * Channel message delivery between routers was broken after the
2126 channel key distribution was fixed earlier. The channel key
2127 was used be to distributed to other routers as well which is not
2128 allowed by the protocol. Now this is fixed and channel keys
2129 really are cell specific and the channel message delivery between
2130 routers comply with the protocol specification.
2132 * Fixed various commands in server to check also the global list
2133 for the channel entry and not just the local list. The affected
2134 file silcd/command.c.
2136 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Added assert()s to buffer formatting and unformatting routines
2139 to assert (if --enable-debug) when error occurs. Affected
2140 file: lib/silcutil/silcbuffmt.c.
2142 * Changed to auto-reconnect to check whether the remote host is
2143 router and register the re-connect timeout if it is. It used
2144 to check that whether we are normal server, but router must do
2145 auto-reconnect with another router as well. Affected file
2148 * Removed the [<key len>] option from CMODE command as the cipher
2149 name decides the key length, nowadays. See the defined ciphers
2150 from the protocol specification.
2152 * Added [<hmac>] option to the CMODE command to define the HMAC
2153 for the channel. Added SILC_CMODE_HMAC channel mode.
2155 * Added [<hmac>] option for the JOIN command so that user can
2156 select which HMAC is used to compute the MACs of the channel
2159 * Added Hmac field to the Channel Message Payload. The integrity
2160 of plaintext channel messages are now protected by computing
2161 MAC of the message and attaching the MAC to the payload. The
2162 MAC is encrypted. Now, it is clear that this causes some
2163 overhead to the size of the packet but rationale for this is that
2164 now the receiver can verify whether the channel message decrypted
2165 correctly and also when private keys are set for the channel the
2166 receiver can decrypt the packet with several keys and check from
2167 the MAC which key decrypted the message correctly.
2169 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2170 lib/silccrypt/silccipher.[ch].
2172 * Added silc_hash_len to return the digest length into the
2173 lib/silcrypt/silchash.[ch].
2175 * Rewrote parts of Silc Channel Payload interface in the
2176 lib/silccore/silcchannel.[ch]. The encode function now also
2177 encrypts the packet and parse function decrypts it.
2179 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2181 * Fixed a minor formatting bug in the SKE's key material processing.
2182 It actually might have processed the keys wrong way resulting
2185 * Redefined the mandatory HMAC algorithms and added new algorithms.
2186 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2187 and hmac-md5 truncated to 96 bits. The mandatory is now
2188 hmac-sha1-96. Rest are optional (including the one that used
2189 to be mandatory). Rationale for this is that the truncated HMAC
2190 length is sufficient from security point of view and can actually
2191 make the attack against the HMAC harder. Also, the truncated
2192 HMAC causes less overhead to the packets. See the RFC2104 for
2195 * Added new [hmac] configuration section. The SKE used to use
2196 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2197 is of course wrong. The official names that must be proposed in
2198 the SKE are the ones defined in the protocol specification
2199 (hmac-sha1-96 for example). The user can configure any hmac
2200 using any hash function configured in the [hash] section. At
2201 least, the mandatory must be configured.
2203 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2205 * Added HMAC list to the SKE proposal list. It has now both
2206 hash algorithm list and HMAC list. This makes the protocol
2207 incompatible with previous versions. The SKE now seems to work
2208 the way it is supposed to work, for the first time actually.
2210 * Defined plain Hash algorithms to the protocol specification.
2213 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Implemented support for key agreement packets into the server.
2216 Added functions silc_server_key_agreement and
2217 silc_server_send_key_agreement. Other than these functions,
2218 server has nothing to do with this packet.
2220 * Added support for private message key packets into the server.
2221 Added functions silc_server_private_message_key and
2222 silc_server_send_private_message_key.
2226 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2227 called in the protocol's final callback instead in the END
2228 protocol state. This makes a little more sense and in the same
2229 time in client we can use the same protocol routines for normal
2230 key exchange and to key agreement packet handling as well.
2232 * Added to both client's and server's KE protocol context the
2233 SilcSKEKeyMaterial pointer to save the key material. We will
2234 bring the key material to the protocol's final callback by doing
2235 this. The final callback must free the key material.
2237 * Added SKE's packet_send callback into client's KE protocol
2238 context so that the caller can choose what packet sending function
2239 is used. This way we can use different packet sending when
2240 doing normal SKE when doing key agreement packet handling (in
2241 the key agreement packet handling we do not want to encrypt
2244 * Implemented the responder side of the key agreement routines
2245 in the client. The client can now bind to specified port and
2246 accept incoming key negotiation. The key material is passed
2247 to the application after the protocol is over.
2249 * Implemented the processing of incoming Key Agreement packet
2250 in the client. Added function silc_client_key_agreement to
2253 * Implemented the intiator side of the key agreement routines
2254 in the client. The client can now initiate key agreement with
2255 another remote client. The key material is passed to the
2256 application after the protocol is over.
2258 * Created client_keyagr.c to include all the key agreement
2261 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2262 SILC_TASK_CALLBACK except that it is not static.
2264 * Created client_notify.c and moved the Notify packet handling
2265 from the client.[ch] into that file.
2267 * Created client_prvmsg.c and moved all private message and
2268 private message key routines from the client.[ch] into that file.
2270 * Create client_channel.c and moved all channel message and
2271 channel private key routines from the client.[ch] into that file.
2273 * Changed silc_client_get_client_by_id_resolve to resolve with
2274 WHOIS command instead of IDENTIFY command, in the file
2275 lib/silclient/idlist.c.
2277 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Implemented the SKE's responder side to the Client library.
2281 * When FAILURE is received to the protocol do not trust it
2282 blindly. Register a timeout to wait whether the remote closes
2283 the connection as it should do it, only after that process the
2284 actual failure. This was changed to both client and server.
2286 * Added client_internal.h to include some of the structures
2287 there instead of client.h in lib/silcclient/.
2289 * Added function silc_task_unregister_by_callback to unregister
2290 timeouts by the callback function.
2292 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Some "Incomplete WHOIS info" errors has been appearing on the
2295 log files. Took away the entry->userinfo check from WHOIS
2296 reply sending. The entry->userinfo is now " " if client did not
2297 provide one. I thought this was fixed earlier but something
2298 is wrong still. Let's see if the error still appears.
2300 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Fixed a minor bug in the login when the channel key is
2303 re-generated in the server. It used to generate the key in
2304 wrong order and thus caused problems in the channel traffic.
2306 * Fixed a minor bug in channel key distsribution after
2307 KICK command. The key was not sent to the router even though
2310 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2312 * Added silc_ske_process_key_material_data as generic routine
2313 to process any key material as the SILC protocol dictates. The
2314 function is used by the actual SKE library but can be used by
2315 applications as well. This relates to the private message keys
2316 and the channel private keys since they must be processed the
2317 same way the normal SILC session keys. The protocol dictates
2318 this. Affected files: lib/silcske/silcske.[ch].
2320 Added also silc_ske_free_key_material to free the
2321 SilcSKEKeyMaterial structure.
2323 * Defined silc_cipher_set_key function to set the key for
2324 cipher without using the object's method function. The affected
2325 files: lib/silccrypt/silccipher.[ch].
2327 * Implemented silc silc_client_add_private_message_key,
2328 silc_client_add_private_message_key_ske,
2329 silc_client_del_private_message_key,
2330 silc_client_list_private_message_keys and
2331 silc_client_free_private_message_keys functions in the
2334 Added functions silc_client_send_private_message_key to send
2335 the Private Message Key payload and silc_client_private_message_key
2336 to handle incoming Private Message Key payload.
2338 * Added Cipher field to the Private Message Key payload to set
2339 the cipher to be used. If ignored, the default cipher defined
2340 in the SILC protocol (aes-256-cbc) is used.
2342 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Removed lib/silcclient/ops.h file.
2346 Redefined parts of the SILC Client Library API. Created new
2347 file silcapi.h that deprecates the ops.h file and defines the
2348 published Client Library API. Defined also private message key
2349 API and channel private key API into the file.
2351 This is the file that the application must include from the
2352 SILC Client Library. Other files need not be included by
2353 the application anymore.
2355 * Added new key_agreement client operation callback and also
2356 defined the Key Agreement library API for the application.
2358 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2360 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2361 is used by clients to request key negotiation between another
2362 client in the SILC network. If the negotiation is started it
2363 is performed using the SKE protocol. The result of the
2364 negotiation, the secret key material, can be used for example
2365 as private message key.
2367 Implemented the Key Agreement payload into the files
2368 lib/silccore/silauth.[ch].
2370 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Redefined ciphers for the SILC protocol. Added some new ciphers
2373 and defined the key lengths for the algorithms. Changed the
2374 code accordingly. The default key length is now 256 bits.
2376 * Fixed SKE key distribution function silc_ske_process_key_material
2377 when the key length is more than 128 bits. The default key
2378 length in SILC is now 256 bits.
2380 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2381 to indicate unsupported algorithm.
2383 * Renamed rijndael.c to aes.c and all functions as well.
2385 * Fixed a long standing channel key setting bug in client library.
2386 Weird that it has never surfaced before.
2388 * Fixed bug in channel deletion. If the entire channel is removed
2389 then it must also delete the references of the channel entry
2390 from the client's channel list as the client's channel entry and
2391 the channel's client entry share same memory.
2393 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Implemented CONNECT and SHUTDOWN commands in the client.
2397 * Implemented CLOSE command to the client.
2399 * Added the function silc_idlist_find_server_by_name into the
2400 files silcd/idlist.[ch].
2402 Added the function silc_idlist_find_server_by_conn into the
2403 files silcd/idlist.[ch].
2405 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * DIE command was renamed to SHUTDOWN. Updated the both code
2410 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2411 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2413 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2416 * Added function silc_server_create_connection function to create
2417 connection to remote router. My server implementation actually
2418 does not allow router to connect to normal server (it expects
2419 that normal server always initiates the connection to the router)
2420 so the CONNECT command is only good for connecting to another
2423 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2426 or some other client was kicked from the channel.
2428 Implemented the handling of the notify type to both client
2431 Implemented silc_server_send_notify_kicked to send the KICKED
2432 notify. It is used to send it to the server's primary router.
2434 * Implemented the KICK command into server and client.
2436 * Added `query' argument to the silc_idlist_get_client function
2437 to indicate whether to query the client from server or not if
2440 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2441 to indicate that the client is not channel founder.
2445 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * Removed the rng context from SilcPacketContext structure and
2448 changed that the packet routine uses the Global RNG API.
2450 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Added support for quit message that client can "leave" on the
2453 channel when it quits the SILC. It is ditributed inside the
2454 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2456 Added silc_server_free_client_data that will take the
2457 signoff message as argument.
2459 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2461 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2463 * Updated parts of the protocol specification to keep it up
2466 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2469 payloads in one packet.
2471 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2472 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2473 use now the new List flag.
2475 * Also deprecated the following packet types: REPLACE_ID,
2476 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2478 * Added list support for Notify packet in server.
2480 * Added silc_server_send_notify_channel_change to send the
2481 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2482 the silc_server_send_replace_id.
2484 * Added silc_server_send_notify_nick_change to send the
2485 NICK_CHANGE notify type. Deprecates the function
2486 silc_server_send_replace_id.
2488 * Added silc_server_send_notify_join to send the JOIN notify type.
2489 Deprecates the function silc_server_send_new_channel_user.
2491 * Added silc_server_send_notify_leave to send LEAVE notify type.
2492 Deprecates the function silc_server_send_remove_channel_user.
2494 * Added silc_server_send_notify_cmode and
2495 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2496 types. Deprecates the silc_server_send_set_mode function.
2498 * Added SERVER_SIGNOFF notify type to indicate that server has
2499 quit. This means that all clients on the channel from that
2500 server will drop. This can be also used when netsplit happens.
2502 Deprecated REMOVE_ID packet type since it is not needed anymore
2505 Added silc_server_send_notify_server_signoff to send the
2506 SERVER_SIGNOFF notify type. Deprecates the function
2507 silc_server_send_remove_id.
2509 Added also silc_server_send_notify_signoff to send the
2510 SIGNOFF notify type.
2512 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2513 SILC protocol from this day on. Changed the protocol
2514 specification as well.
2516 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2517 notify type. It is used between routers to notify about
2518 topic changes on a channel.
2520 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2523 * Partly updated the protocol specification to comply with the
2524 changes now made. It is still though a bit outdated.
2526 * The JOIN notify type now takes one extra argument <Channel ID>.
2527 The packet used to be destined to the channel but now the
2528 JOIN type may be sent as list thus it is impossible to
2529 destine it to any specific channel. By adding this argument
2530 it is again possible.
2532 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Added CREDITS file. The CHANGES and CREDITS file will appear
2535 in the distribution as well.
2537 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2540 types in the server's silcd/packet_receive.c.
2542 * Implemented CMODE and CUMODE to work in router environment.
2544 * Fixed minor encoding and decoding buglet from the
2545 lib/silccore/silcmode.c.
2547 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2550 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2552 * Changed all SilcConfigServer* and silc_config_server* to
2553 SilcServerConfig* and silc_server_config*, respectively.
2556 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Associated the ID (client or server ID) to the Authentication
2559 Payload to avoid any possibility of forging. Updated the
2560 protocol specification and the code accordingly.
2562 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * The RSA key length is now save to the RsaKey context in the
2565 key generation process in lib/silccrypt/rsa.c. The key length
2566 is now used to figure out the maximum size of the block allowed
2567 to be encrypted/signed.
2569 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2570 is equivalent to the silc_mp_mp2bin but does not allocate any
2573 * Changed silc_mp_mp2bin API to take length argument. If it is
2574 non-zero then the buffer is allocated that large. If zero, then
2575 the size is approximated using silc_mp_sizeinbase, which however
2578 * Created Global RNG API which is global RNG that application can
2579 initialize. After initializing, any routine anywhere in the
2580 code (including library) can use RNG without allocating a new
2581 RNG object. This was done to allow this sort of use of the
2582 RNG in code that has no chance to allocate RNG object. All
2583 applications currently allocate this and many routines in the
2584 library use this. Affected file lib/silccrypt/silcrng.[ch].
2586 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2587 it to use the Global RNG API.
2589 * Defined Authentication Payload into protocol specification that
2590 is used during SILC session to authenticate entities. It is
2591 used for example by client to authenticate itself to the server
2592 to obtain server operator privileges.
2594 Implemented this payload into the lib/silccore/silcauth.[ch].
2595 Implemented also routines for public key based authentication
2596 as the new protocol specification dictates.
2598 Moved definitions of different authentication methods from
2599 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2601 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2602 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2603 silc_pkcs_verify_with_hash functions into the file
2604 lib/silccrypt/silcpkcs.[ch].
2606 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * The client entry's userinfo pointer must be always valid.
2609 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2610 will fail since it requires the userinfo. Now, the userinfo
2611 is allocated as "" if actual userinfo does not exist. Actually,
2612 it must exist and it is totally Ok to drop client connections
2613 that does not announce the userinfo. However, we will make
2614 this workaround for now.
2616 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2617 to return the remote port by socket.
2619 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2622 SILC_SERVER_PENDING_EXEC and added an new macro
2623 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2624 data or when error occurs while processing the pending command.
2626 Added new argument `destructor' into silc_server_command_pending
2627 and to the SilcServerCommandPending object. This destructor is
2628 now called after calling the pending callback or if error occurs
2629 immediately. If error occurs the actual pending callback won't
2630 be called at all - only the destructor. The destructor may be
2631 NULL if destructor is not needed.
2633 All this applies for client library code as well. Similar
2634 changes were made there as well for the pending commands.
2636 In the client, the application must now allocate the
2637 SilcClientCommandContext with the silc_client_command_alloc
2640 * Added reference counter to the SilcServerCommandContext. Added
2641 function silc_server_command_alloc and silc_server_command_dup
2644 Same type of functions added to the client library for the same
2647 * Removed the cmd_ident from IDListData away since it is now
2648 global for all connections. It is the command identifier used
2649 in command sending and with pending commands. The affected file
2652 * Added reference counter to the SilcSocketConnection objecet to
2653 indicate the usage count of the object. The object won't be
2654 freed untill the reference counter hits zero. Currently only
2655 server uses this, and client ignores it. The client must be
2656 set to use this too later. The affected files are
2657 lib/silccore/silcsockconn.[ch]. Added also the function
2658 silc_socket_dup to increase the reference counter.
2660 This was mainly added because it is possible that the socket
2661 is removed underneath of pending command or other async
2662 operation. Now it won't be free'd and proper DISCONNECTING
2663 flags, etc. can be set to avoid sending data to connection that
2664 is not valid anymore.
2666 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2667 the connection. After that it sets SILC_SET_DISCONNECTED.
2668 It is, however, possible that the socket data is not still freed.
2669 The silc_server_packet_process now checks that data is not
2670 read or written to connection that is DISCONNECTED. The socket
2671 get's freed when the reference counter hits zero.
2673 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Changed the client operation API: channel_message operation's
2676 `sender' is now the client entry of the sender, not the nickname
2677 and the `channel' is the channel entry, not the channel name.
2679 In the private_message operation the `sender' is now also the
2680 client entry of the sender not the nickname.
2682 Affected file is lib/silcclient/ops.h and all applications
2683 using the client operations.
2685 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Moved the calling of ops->connect() from connect_to_server_final
2688 into receive_new_id functin since that is the point when the
2689 client is actually allowed to send traffic to network. The
2690 affected file is lib/silcclient/client.c.
2692 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2695 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2696 (if needs broadcasting) instead of broadcasting the packets one
2697 by one which would make a burst in the network traffic.
2699 * Added `broadcast' argument to the functions in silcd/server.[ch]
2700 silc_server_create_new_channel[_with_id] to indicate whether
2701 to send New Channel packet to primary router.
2703 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * Added new function into the silcd/server.[ch] files:
2706 silc_server_create_new_channel_with_id to create new channel with
2707 already existing Channel ID.
2709 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2710 lib/silccore/silcpacket.h. This packet is used t send list of
2711 Set Mode payloads inside one packet. Server uses this to set
2712 the modes for the channels and clients on those channels, that it
2713 announced to the router when it connected to it. The protocol
2714 specification has been updated accordingly.
2716 * The silc_server_new_channel did not handle the packet coming
2717 from normal server as it normally does not send that. However,
2718 when it announces its channels it does send it. Implemented
2719 the support for that.
2721 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2722 into the file lib/silccore/id.h.
2724 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Fixed memory leaks in the functions silc_idlist_del_client,
2727 silc_idlist_del_channel and silc_idlist_del_server in the file
2728 silcd/idlist.c. All of those leaked like a sieve.
2730 * Fixed some small memory leaks in the client's function
2731 silc_client_notify_by_server.
2733 * Added functions into silcd/server.c: silc_server_announce_clients,
2734 silc_server_announce_channels and silc_server_announce_server.
2735 These functions are used by normal and router server to announce
2736 to its primary router about clients, channels and servers (when
2737 router) that we own. This is done after we've connected to the
2740 These functions effectively implements the following packet types:
2741 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2742 and SILC_PACKET_NEW_ID_LIST.
2744 * Added new functions into the silcd/packet_receive.[ch]:
2745 silc_server_new_id_list, silc_server_new_channel_list and
2746 silc_server_new_channel_user_list to handle the incoming
2747 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2749 * Added support of changing Channel ID in the function
2750 silc_server_replace_id. If the server that announces a channel
2751 to the router already exists in the router (with same name but
2752 with different Channel ID), router is responsible to send
2753 Replace ID packet to the server and force the server to change
2754 the Channel ID to the one router has.
2756 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2757 client that the Channel ID has been changed by the router. The
2758 normal server sends this to the client. Client must start using
2759 the new Channel ID as the channel's ID.
2761 Implemented handling of this new type into lib/silcclient/client.c
2762 into the function silc_client_notify_by_server.
2764 * Added new function silc_idlist_replace_channel_id into the files
2765 silcd/idlist.[ch] to replace the Channel ID.
2767 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Call silc_server_command_identify_check always when processing
2770 the IDENTIFY command in silcd/command.c
2772 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2775 send keepalive packets. The packet can be sent by clients,
2776 servers and routers.
2778 Added function silc_socket_set_heartbeat into the file
2779 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2780 If not set, the heartbeat is not performed. The actual
2781 heartbeat is implemented in the low level socket connection
2782 library. However, application is responsible of actually
2785 Added silc_server_send_heartbeat to send the actual heartbeat
2786 packet into silcd/packet_send.[ch]. Server now performs
2787 keepalive with all connections.
2789 * Added silc_task_get_first function into lib/silcutil/silctask.c
2790 to return the timeout task with shortest timeout. There was a bug
2791 in task unregistration that caused problems. TODO has been
2792 updated to include that task system must be rewritten.
2794 * The client library will now resolve the client information when
2795 receiving JOIN notify from server for client that we know but
2796 have incomplete information.
2798 * Rewrote parts of silc_server_remove_from_channels and
2799 silc_server_remove_from_one_channel as they did not remove the
2800 channel in some circumstances even though they should've.
2802 * Encryption problem encountered in server:
2804 The LEAVE command used to send the Channel Key packet to the
2805 router immediately after generating it. However, the code
2806 had earlier sent Remove Channel user packet but not immediately,
2807 ie. it was put to queue. The order of packets in the router
2808 was that Channel Key packet was first and Remove Channel User
2809 packet was second, even though they were encrypted in the
2810 reverse order. For this reason, MAC check failed. Now, this
2811 is fixed by not sending the Channel Key packet immediately but
2812 putting it to queue. However, this is more fundamental problem:
2813 packets that are in queue should actually not be encrypted
2814 because packets that are sent immediately gets encrypted
2815 actually with wrong IV (and thus MAC check fails). So, packets
2816 that are in queue should be encrypted when they are sent to
2817 the wire and not when they put to the queue.
2819 However, the problem is that the current system has not been
2820 designed to work that way. Instead, the packet is encrypted
2821 as soon as possible and left to the queue. The queue is then
2822 just purged into wire. There won't be any fixes for this
2823 any time soon. So, the current semantic for packet sending
2826 o If you send packet to remote host and do not force the send
2827 (the packet will be in queue) then all subsequent packets to the
2828 same remote host must also be put to the queue. Only after the
2829 queue has been purged is it safe again to force the packet
2832 o If you send all packets immediately then it safe to send
2833 any of subsequent packets through the queue, however, after
2834 the first packet is put to queue then any subsequent packets
2835 must also be put to the queue.
2837 Follow these rules and everything works fine.
2839 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * Added new function silc_server_remove_clients_by_server to
2842 remove all client entries from ID list when the server connection
2843 is lost. In this case it is also important to invalidate all
2844 client entires as they hold the invalid server entry. This
2845 fixes fatal bug when server has lost connection and will reconnect
2848 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Made some sanity checks to silc_server_daemonise like to check
2851 whether the requested user and group actually exists.
2853 * Added sanity check to SKE's silc_ske_responder_finish to check
2854 that the public and private key actually is valid.
2856 * Invalidate the client's nickname when receiving Replace ID
2857 packet and the Client ID is being replaced. This means that the
2858 server will query the nickname if someone needs it (client)
2861 * Sort the ID Cache in client library when the ID Cache data
2862 has changed (needs sorting).
2864 * Do not allow for SILC client to create several connections to
2865 several servers. The client does not support windows right now
2866 and generating multiple connections causes weird behaviour.
2868 Irssi-silc client does support windows and can handle several
2869 connections without problems, see: www.irssi.org and SILC plugin.
2871 * Fixed some places where client was added to the IDList. The
2872 rule of thumb is following (in order to get everything right):
2873 If the client is directly connected local client then the
2874 `connection' argument must be set and `router' argument must be
2875 NULL to silc_idlist_add_client function. If the client is not
2876 directly connected client then the `router' argument must
2877 bet set and the `connection' argument must be NULL to the
2878 silc_idlist_add_client function.
2880 * The funtion silc_server_packet_send_local_channel actually did
2881 not check whether the client was locally connected or not. It
2882 does that now. Fixed a bug related to LEAVE command.
2884 * Fixed Remove Channel User payload parsing bug in server's
2885 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2887 * The server's silc_server_save_channel_key now checks also the
2888 global ID list for the channel as it might not be in the local
2889 list. Fixed a bug related to LEAVE command.
2891 * Is this the end of the [<unknown>] buglet that has been lurking
2892 around for a long time? A little for loop fix in server's
2893 silc_server_command_whois_parse that is used by both IDENTIFY
2894 and WHOIS command. At least, this was a clear bug and a cause
2895 of one type of [<unknown>] buglet.
2897 * WHOIS and IDENTIFY commands call the function
2898 silc_server_command_[whois/identify]_check function even if
2899 we are not router server.
2901 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Added --with-gmp configuration option. If set the GMP
2904 is always compiled in the SILC source tree. If not set then
2905 it is checked whether the system has the GMP3 installed. If
2906 it has then the GMP won't be compiled (the system's headers
2907 and library is used), if it doesn't have it then the GMP is
2908 compiled in the SILC source tree.
2910 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Changed RSA private exponent generation to what PKCS #1
2913 suggests. We try to find the smallest possible d by doing
2914 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2915 not security fix but optimization.
2917 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added new config entry [Identity] to fork the server and run
2920 it as specific user and group. A patch from Bostik.
2922 * Imported Dotconf configuration library into lib/dotconf.
2923 This will be used to create the SILC configuration files later.
2924 It will appear in the distsribution after this commit.
2926 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * A big code auditing weekend happening. Auditing code for
2929 obvious mistakes, bugs and errors. Also, removing any code
2932 Removed files for being obsolete:
2934 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2935 inline in the file lib/silcutil/silcbuffer.h)
2937 o lib/silcutil/silcbufutil.c (the header has inline versions)
2939 Changed code to fix possible error conditions:
2941 o The buffer formatting routines now check that the destination
2942 buffer really has enough space to add the data. This applies for
2943 both buffer formatting and unformatting
2944 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2945 unformatting was changed to accomodate following rules:
2946 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2947 sent to the function while XXX_*STRING will not allocate or copy
2948 the data into the buffer. Instead it sets the pointer from the
2949 buffer into the pointer sent as argument (XXX_*STRING used to
2950 require that the pointer must be allocated already). This change
2951 makes this whole thing a bit more consistent and more optimized
2952 (note that the data returned in the unformatting with XXX_*STRING
2953 must not be freed now). The routines return now -1 on error.
2955 o Tried to find all code that use buffer_format and buffer_unformat
2956 and added return value checking to prevent formatting and
2957 especially unformatting errors and possible subsequent fatal
2960 o Changed ske->x and ske->KEY to mallocated pointers in
2961 lib/silcske/silcske.h. Fixed possible data and memory leak.
2963 o Added return value checking to all *_parse* functions. Fixed
2964 many memory leaks as well.
2966 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2967 so that buffer overflows would not happen. All code now also
2968 checks the return value as it can fail.
2970 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2972 * Added reconnection support to server if the normal server looses
2973 its connection to the router (for example if router is rebooted).
2974 The server performs normal reconnection strategy implemented
2975 to the server. Affected file silcd/server.c.
2977 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Added new packet type SILC_PACKET_SET_MODE that is used to
2980 distribute the information about changed modes (for clients,
2981 channels and clients channel modes) to all routers in the
2982 network. Updated the protocol specification accordingly.
2984 Added functions into silcd/packet_send.c and
2985 silcd/packet_receive.c: silc_server_send_set_mode,
2986 silc_server_set_mode.
2988 Added new files silcmode.[ch] into lib/silccore that implements
2989 the encoding and decoding of Set Mode Payload. Added new type
2990 SilcSetModePayload. Moved the definitions of different modes
2991 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2993 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Oops, a little mistake in server's connection authentication
2996 protocol. The protocol is not ended with FAILURE but with
2997 SUCCESS if the authentication is Ok. :) Affected file is
3000 * Implemented NICK_CHANGE notify handling in server in the file
3001 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3002 the local clients on the channel. After the changing nickname
3003 in router environment snhould work and the [<unknown>] nickname
3004 should appear no more.
3006 The silc_server_replace_id function that receives the Replace ID
3007 payload now sends the NICK_CHANGE notify type also in the file
3008 silcd/packet_receive.c
3010 * Changed WHOIS and IDENTIFY command to support the maximum amount
3011 of arguments defined in protocol specs (3328 arguments). This
3012 fixed a bug that caused problems when there were more than three
3015 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Added extra parameter, command identifier, to the
3018 silc_client_send_command so that explicit command identifier
3021 Changed that ID list routines uses specific command identifier
3022 when sending WHOIS/IDENTIFY requests to the server so that they
3023 can be identified when the reply comes back.
3025 Affected files lib/silcclient/command.[ch],
3026 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3028 * Added `sender' argument to silc_server_packet_send_to_channel
3029 to indicaet the sender who originally sent the packet to us
3030 that we are now re-sending. Ignored if NULL. Affected file
3031 silcd/packet_send.[ch].
3033 * Added some server statistics support in silcd/server_internal.h
3034 SilcServerStatistics structure and around the server code. Also
3035 send some nice statistics information when client is connecting
3038 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Fixed channel ID decoding in server's JOIN command reply in
3041 silcd/command_reply.c
3043 * Fixed braodcasting of replace ID payload to not to send it if
3044 we are standalone server in silcd/packet_receive.c.
3046 * Fixed all channel message sending routines to not to send
3047 packets to clients that has router set, since they are routed
3048 separately in the same function earlier. Affects file
3049 silcd/packet_send.c and all channel packet sending functions.
3051 * In USERS reply, res_argv[i] are not allocated, the table
3052 is allocated. Thus changed that free the table, not its
3055 * In server's whois_check and identify_check if the client is
3056 locally connected do not send any WHOIS commands - they are not
3059 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Fixed some minor bugs in client when sending WHOIS command. The
3062 arguments was in wrong order.
3064 * Removed statis function add_to_channel from server in
3065 silcd/command.c that was previously used with the joining but
3068 * Tested USERS command in router environment successfully with two
3069 routers, two servers and two clients.
3071 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Reorganized the USERS command and command reply in client library
3074 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3075 When the command is given by user we register a pending command
3076 callback that will reprocess the command after the reply has been
3077 received from the server. When reprocessing the packet we then
3078 display the information. Thus, the USERS information is displayed
3079 now in the command callback instead of in the command reply
3080 callback. The processing of the command is same as previously
3081 when server has sent the command reply in the JOINing process.
3083 * Added to USERS command in silcd/command_reply.c to join the client,
3084 we didn't use to know about, to the channel after we've created
3085 a client entry for it. Also, for clienet we did know already still
3086 check whether it is on the channel or not and add it if not.
3088 * Removed silc_server_command_join_notify as the function and its
3091 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Changed the client's pending command handling to the same as the
3094 server's pending command handling. It is also now possible to
3095 execute command reply functions from other command reply
3096 function as the function callbacks for commands and command
3097 replies are one and same. The pending commands are not static
3098 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3099 in client connection context. Thus, pending commands are server
3100 connection specific as it is convenient.
3102 Changed the function silc_client_command_pending and
3103 silc_client_command_pending_del and added new function
3104 silc_client_command_pending_check. Removed the
3105 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3108 * Added cmd_ident, current command identifier, to the client
3109 connection context in lib/silcclient/client.h to keep track on
3110 command identifiers used in command sending. Client's command reply
3111 function handling now supports the mandatory command identifiers.
3113 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3114 funtions in client to fully support pending command callbacks.
3116 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3117 as one of the arguments to the application in the command reply
3120 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3121 before first releasing SILC but came back. Now it is removed again
3122 and should come back nomore. The FORWARDED flag was used only
3123 by the JOINing procedure by forwarding the command packet to router.
3124 Now, the JOINing procedure has been changed to more generic (due
3125 to various router environment issues) and FORWARDED is not needed
3126 anymore for anything. The protocol specification is yet to be
3129 Now, removed silc_server_packet_forward from server and the flag
3130 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3132 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Renamed NAMES command to USERS command. The NAMES was named that
3135 due to historical reasons. Now it is renamed. Also, rewrote
3136 parts of the USERS command. The nickname list is not sent anymore
3137 by the server. Only Client ID and mode lists are sent in the USERS
3138 command. Changed this also to the protocol specification.
3140 The client now resolves the names and stuff after it receives
3141 the USERS list from the server when joining to the channel.
3143 * WHOIS and IDENTIFY commands has been changed to support multiple
3144 Client ID's per command. One can now search for multiple users
3145 in the network by sending only one WHOIS or IDENTIFY command.
3146 Changed the code and the protocol specifications.
3148 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3149 uses silc_server_command_whois_parse to parse the request. */
3151 * If normal server, do not parse the WHOIS and IDENTIFY requests
3152 before sending it to the router. Saves some time.
3154 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Fixed JOIN command on client library. Wrong number of arguments
3157 used to crash the client.
3159 * Added silc_server_channel_has_global function to check whether
3160 channel has global users or not.
3162 * Added silc_server_channel_has_local function to check whether channel
3163 has locally connected clients on the channel.
3165 * The silc_server_remove_from_one_channel now checks whether the
3166 channel has global users or not after given client was removed from
3167 the channel. It also checks whether the channel has local clients
3168 on the channel anymore. If it does not have then the channel entry
3169 is removed as it is not needed anymore.
3171 * The silc_server_notify now checks on JOIN notify whether the joining
3172 client is one of locally connected or global. If it is global then
3173 the channel has now global users on the channel and that is marked
3174 to the channel entry. Also, it now saves the global client to
3175 global list who is joining and JOINs it to the channel. This is
3176 for normal server, that is.
3178 Changed silc_server_send_notify_on_channel,
3179 silc_server_packet_relay_to_channel and
3180 silc_server_packet_send_to_channel check if we are normal server
3181 and client has router set (ie. global client) do not send the
3182 message to that client, as it is already routed to our router.
3184 * Implemented LEAVE notify type handling in silc_server_notify
3187 * Tested LEAVE command in router environment successfully. Tested
3188 with two routers, two servers and two clients.
3192 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3194 * Implemented SIGNOFF notify type handling in silc_server_notify
3197 * silc_server_remove_id now removes the client entry from all channels
3198 it has joined and thusly sends SIGNOFF notify type.
3200 * Rewrote the NAMES list generation in server by removing two excess
3201 loops. The lists are created now inside one loop.
3203 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * silc_server_remove_channel_user checks now also global list
3206 for channel and client.
3208 * silc_server_new_channel_user checks now both local and global
3209 list for channel and client. Fixed a bug in client id decoding.
3210 Used to decode wrong buffer.
3212 * silc_server_channel_message checks now both local and global
3213 list for channel entry.
3215 * Tested channel joining (hence JOIN) in router environment
3216 successfully. Tested with two routers, two servers and two
3219 * Tested channel message sending in router environment successfully.
3221 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Added silc_server_save_channel_key into server.[ch] to save the
3224 received channel key in Channel Key payload processing. It is
3225 also used in JOIN command reply handling.
3227 Equivalent function silc_client_save_channel_key added into
3228 client.[ch] into client library.
3230 * Changed JOIN command reply to send information whether the channel
3231 was created or not (is existing already) and the channel key
3232 payload. Changed protocol specs accordingly.
3234 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3235 the request was sent by ID and not by nickname. Crashed on
3238 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3241 now correctly save the received data.
3243 * silc_server_free_sock_user_data now notifies routers in the
3244 network about entities leaving the network.
3246 At the same time implemented functions silc_server_remove_id
3247 and silc_server_send_remove_id to receive and send REMOVE_ID
3248 packets. The packet is used to notify routers in the network
3249 about leaving entities. The ID removed will become invalid in
3252 * Added function silc_idlist_del_server into server. Removes and
3253 free's server entry from ID list.
3255 * silc_server_private_message function now checks, if we are router,
3256 that the destination ID really is valid ID, naturally.
3258 * In router when NEW_ID packet is received (for new client) the
3259 hash of the Client ID is saved in the ID Cache but the
3260 client->nickname is set to NULL, instead of putting the hash
3263 IDENTIFY command now also checks that client->nickname must be
3264 valid. If it is not if will request the data from the server who
3265 owns the client. Added new function
3266 silc_server_command_identify_check.
3268 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3269 to set the command to already allocated Command Payload.
3271 * Tested private message sending in router environment with two
3272 routers, two servers and two clients. Fixed minor bugs and now
3275 * Fixed segfault from client's NAMES command. Used to crash if
3278 * Forwarded packets must not be routed even if it is not destined
3279 to the receiver. Changed server code comply with this.
3281 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Added `require_reverse_mapping' boolean value to ServerParams
3284 structure. If TRUE (not default) the server will require that
3285 the connecting host has fully qualified domain name.
3287 If the reverse mapping is not required and hostname could not be
3288 found the IP address is used as hostname.
3290 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Implemented version string checking to both client and server.
3293 The check is incomplete currently due to the abnormal version
3294 strings used in development version of SILC.
3296 * Changed all command functions in server to use the new
3299 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Changed char *data to unsigned char *data in ID Cache system to
3302 support binary data as ID Cache data. Changed code to support
3303 binary data in lib/silccore/idcache.c.
3305 * Renamed silc_server_packet_relay_command_reply to
3306 silc_server_command_reply as it is normal packet receiving
3307 function. Rewrote the function to accept command replys for
3308 servers and not only for clients.
3310 * Mark remote router always as registered server if we are connecting
3311 to it. Otherwise, commands sent by the router to us are ignored.
3313 * All ID List find routines now returns the ID Cache Entry pointer
3314 as well if requested.
3316 * WHOIS command works now in router environment, tested with two
3317 routers, two servers and two clients.
3319 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3320 in router environment (as it is almost equivalent to WHOIS) but
3321 hasn't been tested thoroughly. Added new functions:
3323 silc_server_command_identify_parse
3324 silc_server_command_identify_send_reply
3325 silc_server_command_identify_from_client
3326 silc_server_command_identify_from_server
3328 * Disabled route cache adding because adding two different ID's with
3329 same IP replaces the old cache entry thus giving wrong route.
3330 The entry->router->connection is always the fastest route anyway
3331 so route cache may not be needed. Of course, new routes maybe
3332 established after receiving the ID when the entry->router->connection
3333 might not be anymore the most optimal.
3335 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Add route cache for received ID for fast routing.
3339 * Added silc_server_packet_route to route received packet on router
3340 that is not destined to us.
3342 * Renamed silc_server_get_route to silc_server_route_get.
3344 * Added id_string and id_string_len fields into SilcServer to
3345 include encoded ServerID for fast comparing without excess
3346 encoding of the ID's.
3348 * Cleaned up WHOIS command on server side. Added following static
3351 silc_server_command_whois_parse
3352 silc_server_command_whois_check
3353 silc_server_command_whois_send_reply
3354 silc_server_command_whois_from_client
3355 silc_server_command_whois_from_server
3357 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3358 arguments in command replies. All command functions should be
3359 updated to use this macro.
3361 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Minor typo fixes on command reply handling on server.
3365 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3367 * Added silc_server_command_add_to_channel internal routine to add
3368 the client to the channel after router has created the channel and
3369 sent command reply to the server.
3371 * Added generic silc_server_send_command to send any command from
3374 * Use static buffer with ID rendering instead of duplicating data.
3376 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Fixed a channel user mode bug when joining to a channel server gave
3379 everybody channel founder rights, oops.
3381 * We mark ourselves as the router of the incoming server connection
3382 if we are router ourselves. This way we can check in some packet
3383 sending functions whether it is locally connected server. For
3384 incoming router connections we put NULL.
3386 * For router sending packets locally means now always sending the
3387 packet cell wide; to local clients and local servers. For normal
3388 server sending packet locally means sending it to only local
3391 * Fixed the JOIN command to really work in router environment. If the
3392 channel is created it is always created by the router. Router is
3393 also responsible of making the initial joining to the channel,
3394 sending JOIN notify to the sending server and distributing
3395 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3396 does not exist server doesn't do anything else but forward the
3397 command to the router which performs everything.
3399 * Added silc_server_send_channel_key function to send the Channel Key
3402 * Added silc_server_create_channel_key to create new channel key. The
3403 channel key is now re-generated everytime someone joins or leaves
3404 a channel, as protocol dictates. Note: channel->key_len is the
3407 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3410 packet_receive.[ch] to separate packet sending and receiving
3411 routines. The server.[ch] now includes everything else including
3412 actual packet processing (writing and reading data) and other
3415 Renamed silc_server_private_message_send_internal to
3416 silc_server_send_private_message. The routine is still though
3417 used only to relay private messages as server does not send
3418 private messages itself.
3420 Renamed silc_server_new_channel to silc_server_create_new_channel
3421 and added new function sicl_server_new_channel that handles the
3422 incoming New Channel packet. Added also new sending function
3423 silc_server_send_new_channel to send New Channel Payload.
3425 * Added new function silc_server_notify to process incoming notify
3426 packet to the server/router. Server may then relay the notify
3427 to clients if needed.
3429 * Added new function silc_server_new_channel_user to process incoming
3430 New Channel User packet. Router will redistribute the packet and
3431 send JOIN notify to its local clients and locally connected servers
3432 if needed. Normal server will send JOIN notify to its local client
3433 on same channel when received this packet. Added also corresponding
3434 sending function silc_server_send_new_channel_user to sent the
3437 * Added boolean route argument to send_notif_to_channel and
3438 packet_send_to_channel functions to attempt to route the packet
3439 if it is TRUE and send only locally if it is FALSE.
3441 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * silc_server_replace_id now broadcasts the received replace ID
3444 packet if it is not broadcast packet already. The router must
3445 broadcast to inform other routers about changed ID.
3447 * Added backpointer to server's router into SilcServer context in
3448 silcd/server_internal.h.
3450 * Fixed silc_server_packet_broadcast to send correct broadcast
3453 * The channel key is now distributed to the local client as soon
3454 as it is received from the router (in router environment) so that
3455 no other packet may be sent for the channel until client has
3458 * silc_server_remove_channel_user now broadcasts the received
3459 Remove Channel User packet if it is not broadcast packet already.
3460 The router must broadcast to inform other routers about removed
3463 * Added users field into SilcPacketContext that is a reference count
3464 of the context. One can increase the reference count by calling
3465 silc_packet_context_dup which is now changed to just increase the
3466 reference count instead of duplicating the data. The reference
3467 count is decresed by calling silc_packet_context_free that will
3468 free the data after the reference count hits zero.
3470 For now on the packet context and everything allocated into it
3471 (including the raw packet from network) must be freed by calling
3472 the new silc_packet_context_free function. Added also new function
3473 silc_packet_context_alloc that must be used now to allocate the
3474 context. This also means that if a routine is asynchronous from
3475 silc_[client/server]_packet_parse_type the packet context must
3476 be duplicated by calling silc_packet_context_dup. Otherwise it
3477 gets free'd after silc_[client/server]_packet_parse_type returns.
3478 Also, one must remember that if packet is duplicated then its
3479 reference count must be decresed by calling the free function as
3480 many times as it was duplicated.
3482 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3483 from both client and server.
3485 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Made joining to a channel working in router environment.
3489 * Cleaned up JOIN command on server side and create function
3490 silc_server_command_join_channel internal routine to make the
3493 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Changed silc_command_pending list to SilcDList. Also, added
3496 `ident' field to SilcServerCommandPending structure to identify
3497 the reply and to call correct callback.
3499 Added silc_server_command_pending_check function to replace the
3500 corresnponding macro. The silc_command_pending list is not
3503 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3504 to set identifier to previously allocated Command Payload. It
3505 is used to set identifier for command when resending Command
3508 * Added silc_command_payload_encode_payload to encode Command
3509 Payload buffer from SilcCommandPayload structure.
3511 * Added silc_argument_payload_encode_payload to encode Argument
3512 payload buffer from SilcArgumentPayload structure.
3514 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Changed WHOIS command to support router connection on server side.
3517 The whois request is always sent to router unless the server is
3518 standalone server. After server has received the reply from the
3519 router will it send the reply to the client.
3521 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3522 broadcast received broadcast packet. The function is used only
3523 by router. The broadcast packet is always sent to the router's
3526 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3527 render given ID to printable string, for log files for example.
3529 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Made basic router to router connections working. At least they
3532 can now connect to each other but nothing really works the way
3533 they are supposed - yet.
3535 * Added new initiator token to RouterConnection configuration
3536 file in silcd/serverconfig.[ch]. It is used to tell whether we
3537 are the initiator to the remote router or whether we'll expect
3538 the other end to connect.
3540 * Moved registering of listener task to silc_server_init, hence
3541 the server starts listenning as soon as it is run, even if it
3542 does not have connections to other routers. Let's see how well
3545 * Changed default connection retry timeouts for more suitable in
3548 * Removed cipher and such arguments from silc_idlist_add_client
3549 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3550 Added new function silc_idlist_add_data to add the keys and stuff
3553 * Added SilcIDListData structure and added it to SilcClientEntry
3554 and SilcServerEntry as their first field in the structure. This
3555 way we can explicitly cast the ID entries to the SilcIDListData
3556 structure and get common data for the entries. In past, we had
3557 to first check what type of connection it is and then cast it to
3558 correct ID entry type. Now, we can directly cast the opaque
3559 pointer to the SilcIDListData (no matter what ID entry it actually
3560 is) and get the data needed.
3562 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3565 in some circumstances even if threre were timeout tasks, though not
3566 IO tasks, but tasks anyway. Now fixed.
3568 * Defined SilcServerConnection structure to hold connection specific
3569 stuff about directly connected servers and routers. The definition
3570 is currently in silcd/server_internal.h. I thought about having
3571 a bit more important role fro this struct but for now it is used
3572 only when connecting to other server (or router actually).
3574 * Added connecting retry support in server when connecting to
3575 router(s). The retry feature implement exponential backoff
3576 algorithm. Also, added SilcServerParams structure to hold default
3577 parameters for server. For now, it include these retry settings
3578 and are hard coded. After server is moded to be as Silc Server
3579 Library this structure will be more important.
3581 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Changed client librarys channel->clients table to SilcList and
3584 changed code accordingly.
3586 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Changed client's channel table to SilcList and changed code
3589 accordingly. Also changed SilcChannelClientEntry to include back-
3590 pointer to the channel so that client entry can use that structure
3591 as list as well and we have fast cross-reference to the channel.
3592 This change dramatically decreased the complexity of channel
3593 handling with client entry and vice versa (removed one extra
3594 loop when searching for channel entry from many functions).
3596 * Changed server->sim from table to SilcDList and changed code
3599 * NAMES command can now be used from user interface. It will show
3600 the user list on the channel, neatly.
3602 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3603 Code now saves realname of the user if it becomes available.
3605 * Renamed configure.in to configure.in.pre and made ./prepare
3606 script to automatically add correct version string to
3607 configure.in which it creates from configure.in.pre.
3609 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * NAMES command reply now shows users mode with the nickname when
3614 * Moved silc_client_ch[u]mode[_char] functions from
3615 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3616 place sucks, they are utility functions and should be in some
3619 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3621 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3624 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Added TRQ (efficient deque and list library) into lib/trq. This is
3629 a very good list library that is currently used in the SILC. Defined
3630 SilcList API over the library because I didn't like the API very
3631 much. See lib/trq/silclist.h for the API and examples of how to
3632 use the API. Fixed various places in the code to use the new
3633 SilcList API. The SilcList is meant for lists that has a structure
3634 already defined as a list. It is not suitable to add just some
3635 context to the list (in TRQ, the context is the list actually).
3637 So, I defined SilcDList that can be used for the purpose where
3638 predefined list structure does not exit. This can be used as
3639 such list. Now some context just can be added to the SilcDList.
3640 Currently this list is not used in the SILC just yet, though there
3641 are a lot places where this can replace dynamically allocated
3642 tables and I will fix these places, later, to use SilcDList.
3643 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3644 and use TRQ internally).
3646 Also fixed some annoying warning messages that the original TRQ
3647 code generated. Also minor changes to TRQ's Makefile.in.
3649 * Added support for querying by Client ID to both WHOIS and
3650 IDENTIFY commands into server, as required by the protocol.
3652 * Removed method function pointers from SilcBuffer structure. They
3653 weren't used to anything and just increased the context size for
3654 no good reason. This change also made silc_buffer_alloc and
3655 silc_buffer_free functions inline functions.
3657 * Disabled command flooding detection support until it's fixed so
3658 that it accepts commands in but does not execute them more than once
3661 * Added silc_net_localhost(), to return local hostname, into
3662 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3663 that must be initialized before calling silc_client_init.
3665 * Added new function: silc_server_send_notify_on_channels to send
3666 notify messages to all channels client has joined. It is assured
3667 that the message is sent only once per client.
3669 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3670 lib/silcutil/silcutil.[ch] as silc_format function. The new
3671 function is generic and is used by server as well, not only by
3672 the logging routines.
3674 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3675 the provided version string was not acceptable. Added new function:
3676 silc_ske_check_version into lib/silcske/silcske.h. The function
3677 must be implemented by the application (client or server) and it
3678 does not reside in the SKE library. The function checks the version
3679 string remote end sent.
3681 * Added back pointers (to opaque context and to SilcSocketConnection)
3682 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3684 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3685 duplicate packet context structure.
3687 * Changed `notify' client operation to send same arguments as client
3688 receives from server except for ID's. ID's are mapped to correct
3689 ID entry and that is returned. Also, if channel entry is not sent
3690 by server but the notify is for channel the channel entry is sent
3691 to application (otherwise application doesn't know that it is for
3692 channel (library gets it from packet's Destination ID)).
3694 * Added silc_client_remove_from_channels into client library to
3695 remove a client from all channels it has joined to. Used when
3696 received SIGNOFF notify from server. Added also new function
3697 silc_client_replace_from_channels to replace old ID entry with
3698 new ID entry on all channels. Used when received NICK_CHANGE
3701 * Fixed ID Cache list handling in silc_idlist_get_client in
3702 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3703 to get (or query) client by ID.
3705 * Updated TODO list.
3707 * Added connection authentication status message defined by the
3708 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3709 support for these into the code in client and server side.
3711 * Added generic function silc_client_send_command to send any command
3712 with variable argument list. Application should use this function
3713 to send commands if the command functions provided by the library
3714 does not suite for the application's user interface needs.
3716 * Added new `failure' client operation. Application is notified about
3717 received failure packet if client is executing a protocol. In this
3718 case the protocol's execution has failed.
3720 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3721 is required by the protocol.
3723 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3724 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3727 * Added status flag to SilcSKE object to indicate realtime status
3728 of the SKE protocol.
3730 * Application receives now exactly same command reply arguments as
3731 the library receives from server. However, if ID is received the
3732 corresponding ID entry is returned to the application (eg. Client
3733 ID is mapped to correct SilcClientEntry entry and that is returned).
3734 Changed command_reply client operation due to this change.
3736 * Changed all ID's in commands and in command replys as ID Payloads.
3737 Change affected both client and server side codes.
3739 All ID's sent in SILC network (with execption of ID's in SILC
3740 Packet header) are sent in ID Payload to support variable length
3743 * Server now notifies nick changes and notifies all clients on
3744 the channels about the new nickname (about the new Client ID,
3747 * Implemented CMODE command to change channel modes. Supports all
3748 channel modes defined by the protocol specs except ban and invite
3749 lists. (Also, private channel key mode is supported but support for
3750 setting private channel key in client is missing, thus, this mode
3751 has no effect on client side (except that server requires that the
3752 client uses private channel key and normal channel traffic does not
3755 Also, invite mode works per se, but INVITE command does not work
3756 yet correctly, so you can set channel as invite only channel but
3757 inviting clients to the channel does not work (it is yet to be
3758 thought what's the best way to do it).
3760 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3761 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3762 Implemented CUMODE command to change user's mode on the channel.
3763 Supports all modes defined by the protocol specs.
3765 * Added NAMES command reply to return users modes on the channel.
3767 * Removed unnecessary and slow ciphers from lib/silccrypt.
3769 * Set SO_KEEPALIVE option to connection sockets by default.
3771 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3773 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3774 redefined the Notify Payload into protocol specs.
3776 * Added silc_id_payload_parse_id to get ID directly from raw
3779 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3782 accept searching by Client ID as well.
3784 * Added support for LEAVE and SIGNOFF notify types in client library.
3786 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3787 to parse ID Payload from raw data.
3789 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Added flags parameter into silc_ske_assemble_security_properties
3792 function in lib/silcske/silcske.[ch].
3794 * Changed notify client operation to fit better for notify messages
3795 sent by server. The notify payload received from server is now
3796 passed to the application (after parsing it to SilcNotifyPayload).
3797 It is application's responsibility to retrieve the arguments
3798 from the payload and show the message the way it wants. The message
3799 sent by server is implementation specific.
3801 * Changed public keys to comply with the protocol specification.
3802 Old public keys are not supported anymore and are not compatible.
3804 * Removed nickname from Channel Payload as the latest draft removed
3805 it. The client must resolve the nickname from the NAMES command
3806 reply received when it joined the channel.
3808 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3810 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Fixed some errors in protocol specification drafts.
3814 * Created lib/silccore/silcnotify.c to implement Notify Payload
3815 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3816 generic payloads described by protocol specifications. The file
3817 includes implementations for ID Payload and Argument Payload.
3819 * Changed Command Payload implementation to use the new Argument
3820 Payload. Changed command_xxxx_payload to command_payload_xxxx
3821 to comply with SILC coding conventions.
3823 * Added suppport for Argument Payload handling in Notify Payload
3824 implementation as protocol requires it. Added the new support
3825 into server and client lib as well.
3827 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Added support for multiple nicknames on same channel. [n] is
3830 added locally to the nickname if there are more than one same
3831 nicknames on the channel.
3833 * Server now sends all nicknames that matched WHOIS request.
3834 Client also shows the list received from server.
3836 * Added TOPIC command to client side. User can now set and show
3837 current topic on channel.
3839 * Added MOTD command to client and server. Also, server sends the
3840 motd when client connects to the server.
3842 * Changed version strings to comply ISO 8601.
3844 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Fixed protocol error handling in client library. It should now
3847 cope even if the SKE fails for some reason.
3849 * Made new protocol specification drafts for submitting to IETF.
3851 * Implemented TOPIC command to server in silcd/command.c.
3853 * Added two new notify types into lib/silccore/silcnotify.h:
3854 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3855 notify nickname change and topic setting/change on a channel.
3857 * API change of command_reply operation in client library. The
3858 application gets now the status type received from server as well.
3860 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3864 * Cras fixed and optimized the packet handling even further and
3865 it should work now. Minor change to the prototype of function
3866 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3868 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Added new function into lib/silcutil/silcschedule.[ch]:
3871 silc_schedule_with_fd to select() a specified fd. The function
3872 returns after timeout expires or data arrives or goes. The
3873 function is used by packet routines to wait that all data is
3874 received from network.
3876 * Fixed data reading from network in lib/silccore/silcpacket.c.
3877 The code now assures that all data is read from the fd and then
3878 continues packet processing. This was a bug fix since the code
3879 used to drop some data in some circumstances.
3881 * Added new function into lib/silcclient/client.[ch]:
3882 silc_client_start_key_exchange to start key exchange after
3883 connection has been established to server. The code internally
3884 now uses this funtion but its main purpose was to provide it
3885 for applications that perform their own connecting. After
3886 application has created a connection it merely calls this
3887 function to start the key exchange between client and server.
3888 The library takes care of everything else after that.
3890 Updated also lib/silcclient/README to explain the usage of
3893 * Do not send to application information that connection has
3894 been established. Application gets notified it by connect
3897 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Applied cras's patch to add silc_schedule_one function. The
3900 function runs scheduler once and returns.
3902 * Fixed the scheduler after cras messed it up. The timeout
3903 handling works now as it's supposed to work.
3905 * Added into lib/silccore/ silcnotify.h to include notify
3906 message types support. Changed silc_server_send_notify*
3907 functions, in server.[ch], to support those new notify types.
3908 Added the support for the notify types into client library,
3909 as well. Added new notify client operation into ops.h in
3912 * Changed silc_server_packet_send_to_channel to send normal
3913 packets instead of just channel message packets. The function
3914 is now used to send the notify packets to channels. It is not
3915 used to send channel message packets anymore, as server never
3918 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3919 va_arg()s as it seems to require it nowadays. I guess, if SILC
3920 is compiled with older va_arg() the new code should work anyway.
3922 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Splitted core library. Core library (lib/silccore) includes
3925 now only SILC protocol specific core (and common) components.
3926 Created new utility library (lib/silcutil) that includes more
3927 generic purpose stuff. The stuff for util library was taken
3928 from the old core library. This was minor and easy split.
3930 * Created SILC Client Library (lib/silcclient) that includes
3931 implementation of the SILC client without user interface. This
3932 was major move from silc/ directory. The code has been changed
3933 so that it is transparent towards the user interface. The
3934 silc/ directory includes now the same user interface as before
3935 and it uses the new client library. Read lib/silcclient/README.
3936 Basicly, the client library performs everything else related
3937 to SILC except user interface handling. Also, configuration
3938 files are considered to be part of user interface and library
3939 does not handle them.
3941 This change also changed a lot of structures, function naming etc.
3942 Most important change was that SilcClientWindow object was
3943 renamed to SilcClientConnection in the client library. Created
3944 also new file lib/silcclient/ops.h. Also added new files
3945 silc/local_command.[ch] and silc/client_ops.[ch].
3947 All these changes were made to make it easier for user interface
3948 designers to create what ever user interface for the SILC client
3951 It is also expected that the server will be moved to lib
3952 directory as well and SILC Server Library will be created;
3953 sometimes in the future.
3955 * Removed Local commands from lib/silccore/silccommand.h as
3956 they are application specific and new client library does not
3957 handle any of those anymore.
3959 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3960 old client implementation in silc/.
3962 * Added support for callback functions in SILC_LOG_* macros.
3963 Application can now set its own callbacks that will be called
3964 instead of using the default functions that will always print
3965 the debug messages to stderr (or stdout). Also, debugging can
3966 now be disabled by setting silc_debug to FALSE and re-enabled by
3967 setting it to TRUE. Note, that logging will still work even
3968 if debugging is disabled.
3970 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3971 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3972 silc_log_reset_debug_callbacks.
3974 * To enable debugging in silc client one must give now -d
3975 option on command line.
3977 * Changed silc_schedule_init to automatically allocate task queues
3978 if they are not allocated before calling it.
3980 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Added GMP 3.1 into math library.
3984 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3987 a channel in SILC network. The packet is used by servers and
3988 routers to notify other routers that user has left a channel.
3989 This little feature was missing until now. Added the feature
3990 to protocol specification as well.
3992 Added functions: silc_server_send_remove_channel_user and
3993 silc_server_remove_channel_user into server.[ch].
3995 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3996 lib/silccore/silcpacket.h. However, they are not implemented
3999 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed joining to a channel and sending channel messages
4002 between server and router. The channel message sending should
4003 now work inside a cell.
4005 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Fixed the private message sending between server and router.
4008 The private message sending should now work inside a cell.
4010 * Added silc_server_replace_id into server.[ch] to replace
4011 existing ID in the SILC network.
4013 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4014 and silc_idlist_replace_server_id into idlist.[ch] in server.
4016 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Fixed the server to server connections. Server can again now
4019 connect to router. Router to router connections probably does
4022 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added dynamic protocol registering support. Now protocols can
4025 registered and unregistered on the fly. Patch by cras.
4027 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Added lib/contrib directory to hold routines that some platforms
4030 don't have but are needed by SILC.
4032 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4033 into lin/contrib to provide getopt() and getopt_long() for
4034 those who don't have it.
4036 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Added AWAY command to client. When away message is set and
4039 client receives a private message packet the client automatically
4040 replies to the sender with the away message.
4042 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4043 bug seemed to be the cause of recent problems when compiling
4046 * Added version detection support to SKE protocol specification
4047 and added the new changes to the SKE implementation as well.
4048 There were other minor changes in the SKE protocol as well.
4050 Many changes in lib/silcske/silcske.[ch] and in
4051 lib/silcske/payload.[ch].
4053 * Added ^U functionality, clear input line. Patch from cras.
4055 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Mainly small bugfixes on core library. Fixed some debugging
4058 logging and buffer overflow in silclog.c.
4060 * Updated config.sub and config.guess on the distribution tree.
4062 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Added command lagging support in server. Client may execute
4065 commands now only once in two seconds.
4067 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Optimized packet reception. MAC computation and checking is now
4070 also more optimized. A lot previously duplicated code is now
4071 used as generic by both client and server.
4073 * Fixed key pair generation in clientutil.c
4075 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Added into lib/silccore/silcbufutil.[ch] new function;
4078 silc_buffer_realloc.
4080 * Moved generic packet sending/encryption functions to
4081 lib/silccore/silcpacket.[ch] from client and server. Some
4082 rewriting of the functions.
4084 * Moved all generic packet reception/decryption functions to
4085 lib/silccore/silcpacket.[ch] from client and server. The
4086 packet processing is now much cleaner in both client and server.
4087 These were major changes in both client and server.
4089 * Created many common functions in server to do packet sending.
4090 Previously code were duplicated a lot, this has been removed
4093 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4095 * Rewrote major parts of the ID cache system. Don't know
4096 whether it is better now or not but at least the API is more
4099 * Major rewrite on ID cache stuff on client because of the ID
4100 cache API changes. Added idlist.c to client.
4102 * Also major rewrite on ID cache stuff on server as well.
4103 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4104 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4105 in hand, instead they are all put into the ID cache system now.
4106 All server_idlist_* routines uses ID cache now instead of
4107 traversing its own lists (those lists does not exist anymore).
4108 SilcIDList though still exists. Also, SilcXXXEntry's are
4111 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Finally made the SKE implementation compliant to the protocol
4114 specification. All mp integers are now binary encoded as
4115 opposed being HEX encoded.
4117 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4120 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4121 functions: silc_[encode/decode]_pem. Also added function
4122 silc_encode_pem_file to PEM encode with newlines ('\n') for
4125 * SILC public keys are now encoded either PEM or binary. Same
4126 option is for private keys as well. By default private keys
4127 are binary encoded and public keys PEM encoded. Silly HEX
4128 encoding were removed.
4130 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4131 function to create fingerprints.
4133 * Fixed a bug in SHA1; does not change the original data anymore.
4135 * Partly implemented INFO command on client and server side.
4136 Fixed CLEAR command. Changes to SERVER command; show current
4137 server(s) when giving command without arguments. Added
4138 VERSION command to client.
4140 * Added check to server that unregistered connections cannot
4141 execute commands (unless it is specificly allowed).
4143 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Fixed screen refresh.
4147 * Fixed channel joining bug from client. On some circumstances
4148 client tried to join to a channel it had already joined.
4150 * Added public key verification process into client's protocol.c.
4151 The client now verifies the public key from user and saves
4152 it into ~./silc/serverkeys/ directory.
4154 Added into: clientutil.[ch]: silc_client_verify_server_key.
4156 * Changed SKE protocol's silc_ske_initiator_finish function
4157 to accept callback function that verifies the received public
4158 key. Removed old silc_ske_verify_public_key function.
4160 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4163 silc_pkcs_private_key[_data]_set.
4165 * Made the password and public authentication more cleaner in
4166 server's protocol.c.
4168 * Removed historic and obsolete protocol `channel_auth' from
4169 both client and server.
4171 * Removed wrong way of sending command status messages from
4172 server to client in server's command.c. The old way violated
4173 protocol specification.
4175 Changes to silccore/silccommand.[ch]: removed
4176 silc_command_encode_status_payload -> not needed anymore,
4177 changed silc_command_encode_payload_va to accept extra
4178 argument on variable argument list. The argument type must
4179 now be provided to the function. Also, added new function:
4180 silc_command_encode_reply_payload_va which is same as
4181 normal command_encode_payload_va except command status type
4182 is provided as extra argument.
4184 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added ~./silc directory handling. The directory includes the
4187 public and private keys for the client.
4189 Added silc_client_check_silc_dir, silc_client_create_identifier
4190 and silc_client_load_keys.
4192 * Implemented SILC protocol compliant public key. Added public
4193 and private key saving to and loading from files.
4195 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4196 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4197 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4198 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4199 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4201 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4202 silc_pkcs_load_[public/private]_key.
4204 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Added silc_server_get_route (route.[ch]) to get connection
4207 data for the fastest route for given ID.
4209 * Implemented INVITE command on client and server. The command
4210 were re-defined in the SILC Protocol Specification and the
4211 implementation now complies with the specification.
4213 * Implemented PING command on client and server.
4215 * Implemented NAMES command on client and server. The server side
4216 supports currently only normal server not router server yet.
4217 Some changes to NAMES definition in SILC protocol specification.
4219 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Implemented LEAVE command on client and server.
4223 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4224 again. This change was made to the protocol as well. Server
4225 should not violate the protocol specification anymore.
4227 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4230 was tested. SOCKS4 was not but should work anyway.
