1 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the backup resuming protocol to work in multiple
4 router environment. Affected file silcd/server_backup.c.
6 * Route packet only to one router in the function
7 silc_server_packet_send_to_channel. Affected file is
10 * Fixed silc_server_send_notify_dest to set the broadcast
11 flag. Fixed the silc_server_send_notify_topic to actually
12 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
13 Affected file silcd/packet_send.c.
15 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
17 * Changed the backup router adding and getting interfaces
18 in the server. The router that will be replaced by the
19 specified backup router is now sent as argument. Affected
20 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
23 * Added silc_net_addr2bin_ne to return the binary form of
24 the IP address in network byte order. Affected files
25 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
27 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
29 * Check for existing server ID in silc_server_new_server
30 and in silc_server_connect_to_router_final and remove the
31 old entry if it exists. Affected file silcd/packet_receive.c,
34 * Send the channel message always to only one router, either
35 in upstream or downstream. Affected file is
38 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
40 * Wrote the definition of the backup resuming protocol to the
41 protocol specification.
43 * Removed one redundant channel key generation from normal
44 server during joining procedure. Removed one redundant
45 channel key sending from server to router during joining
46 procedure. Affected file silcd/command.c.
48 * Made minor bugfixes to the backup router resuming protocol.
49 Affected file silcd/server_backup.c, server.c.
51 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
53 * Added --disable-asm configuration option. Affected files
54 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
57 * Implemented the backup resuming protocol that is used to
58 resume the primary router position in the cell after the
59 primary router comes back online. Affected files
60 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
61 and silcd/server_util.[ch].
63 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
65 * Sleep two (2) seconds after sending QUIT command to server.
66 Affected file lib/silcclient/command.c.
68 * Assure that if outgoing data buffer is pending do not force
69 send any data. Affected file silcd/packet_send.c.
71 * Assure that if outgoing data buffer is pending do not force
72 send any data. Affected file lib/silcclient/client.c.
74 * Implemented the backup router support when the primary router
75 goes down. The servers and routers can now use the backup
76 router as new primary router without loosing connectivity.
78 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
80 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
81 in the server to indicate disabled entry. All data read
82 from the connection will be ignored and no data is sent
83 for entry that is disabled. Affected files are
84 silcd/idlist.h, silcd/server.c.
86 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
88 * Created SFTP client and server test programs in the
89 lib/silcsftp/tests directory.
91 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
93 * Implemented memory filesystem (virtual filesystem) for
94 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
97 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
99 * Implemented the SFTP (SSH File Transfer Protocol) to the
100 lib/silcsftp. It includes SFTP client and SFTP server
103 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
105 * Moved lib/silccore/silcprotocol.[ch] to the
106 lib/silcutil library.
108 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
109 take variable argument list pointer as argument. Affected
110 file lib/silcutil/silcbuffmt.[ch].
112 * Added silc_buffer_set function that is used to set data
113 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
114 Affected file lib/silcutil/silcbuffer.h.
116 * Changed various routines in the core library to use the new
117 silc_buffer_set instead of allocating new buffer only for
120 * Added 64-bit value formatting and unformatting support to the
121 silc_buffer_[un]format routines. Affected file is
122 lib/silcutil/silcbuffmt.[ch].
124 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
125 to includes/bitmove.h.
127 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
129 * Fixed channel user mode saving in client library. Affected
130 file lib/silcclient/command[_reply].c.
132 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
134 * Defined the file transfer to the SILC Protocol. Added
135 new packet type SILC_PACKET_FTP and defined File Transfer
136 Payload. The mandatory file transfer protocol is SFTP
137 (SSH File Transfer Protocol). Affected file in addition
138 of the internet draft is lib/silccore/silcpacket.h.
140 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
141 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
142 is used as part of backup router protocol when the primary
143 router of the cell is back online and wishes to resume
144 the position as primary router.
146 * Redefined the MAC generation keys in the protocol. The
147 same key is not used anymore in both direction. Both
148 direction will now use different keys for sending and
149 receiving. This fixes a potential security flaw. This
150 change causes incompatibilities in the protocol.
152 * Redefined also the MAC computation from the packet.
153 An packet sequence number is now added to the MAC
154 computation. This prevents possible replay attacks against
155 the protocol. This change too causes incompatibilities
158 Added `sequence' field to the SilcPacketContext to hold
159 the current sequence number for the packet.
161 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
163 * Added `created' field to the SilcIDListData in the file
164 silcd/idlist.h to indicate the time when the entry was
167 * Added `created' field to the SilcChannelEntry too. Affected
170 * Added `creation_time' aguments to all the announcement functions
171 in the server. If it is provided then only the entries that
172 was created after the provided time frame are actually
173 announced. Affected file silcd/server.[ch].
175 * The protocol says that the Channel ID's IP address must be
176 based on the router's IP address. Added check for this in
177 the silc_server_new_channel when processing incoming New Channel
178 Payload. Affected file silcd/packet_receive.c.
180 * Print out the correct version with --version in SILC client.
181 Affected file irssi/src/silc/core/silc-core.c.
183 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
185 * Fixed WHOWAS command to check for completnes of the client
186 entry always, not just when the command is coming from client.
187 Affected file silcd/command.c.
189 * Added new function silc_server_packet_queue_purge to purge the
190 outgoing data queue to the network. After the function returns
191 it is guaranteed that the outgoing packet queue is empty.
192 Affected file silcd/packet_send.[ch].
194 * Purge the outgoing packet queue in the rekey protocol's final
195 callback to assure that all rekey packets go to the network
196 before quitting the protocol. Affected file silcd/server.c.
198 * Added silc_client_packet_queue_parse as similar function as
199 in server to the client library. The affected file is
200 lib/silcclient/client.c.
202 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
204 * Splitted silcd/server.c and created silcd/server_util.[ch]
205 for utility functions.
207 * Added new socket flag SILC_SF_DISABLED to indicate that the
208 connection is open but nothing can be sent to or received from
209 the connection. Affected file lib/silcutil/silsockconn.[ch].
210 The checking for disabled socket is checked in the low level
211 silc_socket_write and silc_socket_read functions.
213 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
215 * Allow only nicknames and channel names that fits into the
216 7-bit unsigned char ASCII set. Affected file silcd/command.c.
218 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
220 * When processing JOIN command reply in server check that if
221 the channel exists in our global list we'll move it the local
222 list. Affected file silcd/command_reply.c.
224 * Fixed the check whether client is joined on the channel already
225 in JOIN command. Affected file lib/silcclient/command.c.
227 * Fixed the JOIN command reply to check whether the channel
228 already exists. Affected file lib/silcclient/command_reply.c.
230 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
232 * Added silc_ske_status_string to map the SKE error numbers
233 to readable strings. The affected files are
234 lib/silcske/silcske[_status].[ch].
236 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
238 * Do not show the private channels on the WHOIS channel list
239 as it is not allowed by the protocol. The affected file is
242 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
244 * Assure that the packet length digged from the actual packet
245 is something sensible in the silc_packet_decrypt_rest_special
246 in lib/silccrypt/silcpacket.c.
248 * Free and NULL the allocated pointer in silc_hmac_alloc if
249 the HMAC allocation fails. The affected file is
250 lib/silccrypt/silchmac.c.
252 * Print the selected security properties to the log files in
253 the server. Affected file silcd/protocol.c.
255 * Add SKE's reference counter even if calling the completion
256 callback manually. Otherwise it goes negative, although it
257 does not cause any problems. The affected file is
258 lib/silcske/silcske.c.
260 * Remove the client entry with short timeout after giving the
261 KILL command. Affected file lib/silcclient/command.c.
263 * Fixed to send error reply in WHOIS and IDENTIFY commands in
264 case all found clients are already disconnected (WHOWAS would
265 found them) in the server. Affected file silcd/command.c.
267 * Update the last_receive (time of last data received) to be
268 updated only when received private or channel message so that
269 the idle time showed in WHOIS makes more sense.
271 * Added boolean field `valid' in to the SilcClientEntry in the
272 client library to indicate whether the entry is valid or not.
273 This fixes the nickname change bug on channel when changing
274 the nickname to be same than the old (like nick to Nick) the
275 nickname formatter doesn't set the new nick anymore to Nick@host.
276 Affected file lib/silcclient/idlist.[ch].
278 * Now actually fixed the nickname changing on disconnection.
279 Added new function silc_change_nick to the Irssi SILC Client.
280 Affected file irssi/src/silc/core/client_ops.c,
281 irssi/src/silc/core/silc-nicklist.[ch].
283 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
285 * Check that the public key exists in the GETKEY command before
286 trying to encode it. Affected file silcd/command.c.
288 * Print some notifications on received public keys with GETKEY
289 command in the Irssi SILC Client. Affected files are
290 irssi/src/fe-common/silc/module-formats.[ch],
291 irssi/src/silc/core/client_ops.c.
293 * Use IDENTIFY command to resolve the server information in the
294 GETKEY command instead of INFO command. Affected file
295 lib/silcclient/command.c.
297 * All command reply functions in the client library now calls
298 the pending command reply callbacks even if an error has
299 occurred. The server has done this a long time and now it was
300 time to move the client library to this as well. Now all
301 errors can be delivered back to the pending command reply
302 callbacks if necessary. Affected files are
303 lib/silcclient/command[_reply].[ch].
305 * Change the nickname on disconnection back to the username
306 because in reconnect the server will enforce it to it anyway.
307 Affected file irssi/src/silc/core/silc-servers.c.
309 * Fixed a config file parsing bug in the Irssi SILC client.
310 Affected file irssi/src/silc/core/clientconfig.c.
312 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
314 * When printing the channel mode on JOIN, verify that the
315 channel key and channel's HMAC are valid. Affected file
316 irssi/src/silc/core/client_ops.c.
318 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
320 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
321 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
322 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
324 * Removed channel key rekey task deleting from the function
325 silc_server_save_channel_key. Affected file silcd/server.c.
326 Added explicit timeout task context instead that is used to
327 delete the task if we are registering a new task before the
328 new task has elapsed.
330 * When channel key rekey occurs the client library now saves
331 the old channel key for a short period of time (10 seconds) and
332 is able to use it in case some is still sending channel
333 messages encrypted with the old key after the rekey. Affected
334 file lib/silcclient/[idlist.h|client_channel.c].
336 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
338 * Added check to the silc_server_new_id_real to not accept
339 new ID if it is the sender's own ID. Affected file is
340 silcd/packet_receive.c.
342 * Assure that we do not announce ourself or the one we've
343 sending our announcements when we're router and are announcing
344 servers to our primary router. Affected file silcd/server.c.
346 * Fixed silc_server_command_identify_check_client to assemble
347 correct WHOIS packet. It send corrupted WHOIS packet and
348 caused problem with router to router connections. Affected
349 file silcd/command.c.
351 Fixed also silc_server_command_whois_check the same way
352 as for the IDENTIFY command.
354 * Added new SilcIDListStatus to the server in the SilcIDListData
355 structure. The status now includes the current status of
356 the entry (like registered, resolved etc.). Affected file
357 silcd/idlist.[ch]. Defined a bunch of different status types
358 as well. This replaced the old boolean registered field as well.
360 Added resolve_cmd_ident field to the SilcClientEntry structure
361 too so that if the entry is for example being resolved so
362 another command may attach to the same pending command reply
363 without requiring to resolve the same entry again. This concept
364 should optimize the WHOIS and the IDENTIFY resolving under
365 heavy load by taking away unnecessary resolving for entries
366 that are being resolved already.
368 Added support for adding multiple pending commands for one
369 command idenfier. Affected file silcd/command[_reply].[ch].
371 * Fixed WHOIS and IDENTIFY save to remove the cache entry
372 before deleting the data. Otherwise the hash table will have
373 freed data in comparison functions. Affected file is
374 silcd/command_reply.c.
376 * Fixed silc_idlist_replace_client_id to add the new entry to
377 the cache with NULL nickname. Otherwise there will be invalid
378 memory as the nickname after the nickname is freed. Affected
379 file silcd/packet_receive.c.
381 * Fixed the silc_idlist_get_clients_by_hash. The entries was
382 saved into wrong slots because the previous number of entries
383 was not taken into account. Affected file silcd/idlist.c.
384 Fixed same thing in silc_idlist_get_clients_by_nickname too.
386 * If we are router and we receive JOIN notify to a channel that
387 does not have any users then notified client is marked as the
388 channel founder, as it is it. The affected file is
389 silcd/packet_receive.c
391 * Added to the extended hash table API's table_del_*ext functions
392 the destructor as argument too, so that the caller can decide
393 which destructor to use or whether to use destructor at all.
394 Affected file lib/silcutil/silchashtable.[ch].
396 * Fixed ID Cache purging. It actually deleted the entries from
397 the hash table after the data was freed. The hash table ended
398 up comparing freed memory. The affected file is
399 lib/silccore/silcidcache.c.
401 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
403 * Fixed Irssi SILC client's KILL command's HELP syntax.
405 * The USERS command now resolves the detailed user information
406 if the userinfo field is missing. Affected file is
407 lib/silcclient/command_reply.c.
409 * Do not print error in silc_file_read if the read file does
410 not exist. Just silently return NULL. Affected file is
411 lib/silcutil/silcutil.c.
413 * Fixed the silc_log_output to not wine about NULL filename
414 and to not create some bogus " " filename. Affected file is
415 lib/silcutil/silclog.c.
417 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Fixed various printing bugs on the user interface in the
420 Irssi SILC Client. Minor changes that were forgotten from
423 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
425 * Fixed the configure.in.pre and the compilation and distribution
426 environment to support the new autoconf 2.52. That version is
427 now required to compile the CVS trunk.
429 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Renamed function silc_parse_nickname to silc_parse_userfqdn
432 to generally parse user@fqdn format strings. Affected file
433 lib/silcutil/silcutil.c.
435 * Added nickname_format and nickname_force_format fields to the
436 SilcClientParams structure. The first one defines the format
437 for the nicknames that the library will enforce if the receives
438 multiple same nicknames. The second one is boolean value and
439 can be used to force the library to always enforce the format
440 to the nicknames regardles whether there are multiple nicknames
441 or not. This configurable formatting was employed to flexibly
442 support accessing multiple nicknames from the user interface.
443 The userinterface can now set the nicknames to what ever format
444 they prefer. Affected file lib/silcclient/silcapi.h.
446 Added function silc_client_nickname_format to the file
447 lib/silcclient/idlist.c. It performs the nickname formatting.
449 Added new field `hostname´ to the SilcClientEntry context.
450 It holds the hostname of the client. Affected file is
451 lib/silcclient/idlist.h.
453 * Irssi SILC Client sets the nicknames in nick@hostn format.
454 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
455 irssi/src/silc/core/silc-core.c.
457 The WHOIS printing now also shows both the real nickname and
458 the formatted nickname so that user knows how to access the
459 user if there are multiple same nicknames cached. Affected
460 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
461 printing formatting too to take the hostname now as a separate
462 argument. The Affected file is
463 irssi/src/fe-common/silc/modules-formats.[ch].
465 * Changed the silc_client_get_clients_local to accept the formatted
466 nickname as argument. It accepts the real nickname too but the
467 formatted nickname can be used to find the true entry from
468 multiple entries. Affected file lib/silcclient/silcapi.h and
469 lib/silcclient/idlist.c.
471 * Added nickname_format_parse field to the SilcClientParams.
472 It is a callback function provided by the application to parse
473 the nickname out of the formatted nickname string. The library
474 calls it to get the nickname from the formatted string. Since
475 the application generally knows better the format of the nickname
476 string it parses it instead of the library, even though library
477 encodes the formatted string. If the callback function is not
478 provided then the library will use the string as is. The
479 affected file is lib/silcclient/silcapi.h.
481 * All the nickname strings passed to the client library in
482 commands are now expected to be formatted nickname strings.
483 If the command does not support the formatted nickname string
484 it will assume that the sent string is the actual nickname.
485 Affected file lib/silcclient/command.c.
487 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
489 * Added public key authentication support to OPER and SILCOPER
490 commands in the client library. Affected file is
491 lib/silcclient/command.c.
493 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Changed the get_auth_methdod client operation to be asynchronous.
496 It can be async if the application resolves the authentication
497 method from the server during the negotiation. Added new
498 SilcGetAuthMeth completion callback that the application will
499 call after resolving the authentication method.
501 Added function silc_client_request_authentication_method that
502 the application can use to resolve the authentication method
503 from the server. Added also SilcConnectionAuthRequest callback
504 that the library will call after the server has replied. The
505 application can call this function if it does not know the
506 current authentication method.
508 Affected files are lib/silcclient/client.c and
509 lib/silcclient/silcapi.h.
511 * The Irssi SILC client now automatically resolves the authentication
512 method incase any configuration information is not present (and
513 currently there never is). The affected file is
514 irssi/src/silc/core/client_ops.c.
516 * Fixed public key authentication from the client library.
517 Affected file lib/silcclient/protocol.c. Changed also the
518 protocol specification about the public key authentication in
519 the connection authentication protocol. The actual data to be
520 signed is now computed with a hash function before signing.
522 * Fixed the public key authentication from the server as well.
523 Affected file silcd/protocol.c.
525 * Removed the mlock()'s from the memory allocation routines.
526 Affected file lib/silcutil/silcmemory.c. The ./configure does
527 not check anymore for the mlock(). Affected file is
530 * Fixed USERS command in server to allow the execution of the
531 command for private and secret channels if the client sending
532 the command is on the channel. Affected file silcd/command.c.
534 * Fixed silc_client_get_clients_local to return the clients
535 count correctly. It could return wrong value. Affected file
536 lib/silcclient/idlist.c.
538 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
540 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
541 types. The assembler optimizations seemed not to like 64-bit
542 data types. The assmebler optimizations thus are now enabled
543 also for BSD systems as opposed to only enable them for Linux.
545 * Do not check for threads at all on BSD systems. Affected
546 file configure.in.pre.
548 * Removed -n and -h options from the Irssi SILC Client since
549 they are not used in silc.
551 * Fixed the prime generation to assure that the first digit
552 of the generated random number is not zero since our conversion
553 routines does not like number strings that starts with zero
554 digit. If zero digit is seen the random number is regenerated.
555 This caused some corrupted RSA keys when the zero first digit
556 was met. Affected file lib/silcmath/silcprimegen.c.
558 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
560 * Fixed WIN32 configuration in the ./configure script.
561 Fixed to include xti.h on environments that has it.
562 Patches by Carsten Ilchmann and andrew.
564 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Changed the silc_id_create_client_id to be collision
567 resistant. It is now assured that there cannot be created
568 two same client ID's. I suspect that some weird bugs in
569 the server were actually caused by duplicate Client IDs.
570 Affected file silcd/serverid.[ch]. A router receiving
571 new ID now also assures and informs the sending server
572 if the ID caused collision.
574 * Changed the silc_id_create_channel_id to also assure that
575 there are no collisions.
577 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Statement about ignoring the Mutual Authentication flag when
580 performing rekey with PFS was a bit misleading. It is ignored
581 if it was set in the initial negotiation, it cannot be even
582 set in the rekey. Fixed in the ke-auth draft. Started the
583 new versions of the protocol drafts in the doc/.
585 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
587 * Fixed a bug in silc_client_command_identify_save when saving
588 new channel information. The channel name was no duplicated
589 and caused crash on exit. Affected file is
590 lib/silcclient/command_reply.c.
592 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
594 * Fixed the getkey command handling in the server. Send just
595 empty OK reply to the sender if the key could not be fetched
596 (but everything else was ok, like the key just was not available).
597 Changed the public key parameter to optional in the protocol
598 specs so that empty OK reply can be sent. Affected file
601 Added a message to Irssi SILC client to tell to user if the
602 server did not return a public key.
604 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Fixed a channel key regeneration bug. It registered new
607 timeout tasks exponentially until all system resources were
608 used. Affected file silcd/server.c.
610 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
612 * Added the SILC Document generator to the scripts/silcdoc.
613 It can be used to generate the Toolkit Reference Manual out
614 of the source tree. Internally it will also use the RoboDoc
615 generator now imported in util/robodoc.
617 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Added couple of return's in rekey protocol if error orccurred
620 during the protocol. The execution must be terminated.
621 Affected file silcd/protocol.c. Also, terminate the protocol
624 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
626 * The client's Client ID was created initally from the wrong
627 nickname (it could have been in format nick@host) in the
628 silc_server_new_client. Affected file silcd/packet_receive.c
630 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Added some SILC_LOG_ERROR's to various error conditions
633 if client could not be added to ID cache. Affected files
634 silcd/packet_receive.c and silcd/server.c.
636 * When client's sock->user_data is freed, NULL also the
637 client->router and client->connection pointers. Added check
638 for these pointers being NULL to various places around the
639 code. Affected file silcd/server.c.
641 * Added client->data.registered == TRUE checks to various
642 places around the code to assure that unregistered client's
643 are not handled when it is not allowed. Affected file
646 * Added `bool registered' fields to all
647 silc_idlist_[server|client]_get_* routines to indicate whether
648 the fetched client needs to be registered or not. Affected
649 file silcd/idlist.[ch].
651 * Add your own entry as registered to the ID cache in the
652 server. Affected file server.c.
654 * Fixed a bug in silc_server_new_server. The SilcServer was
655 set as the new server's context instead of SilcServerEntry.
656 This naturally caused some weird bugs.
658 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Do not delete the channel rekey task when adding it
661 for in silc_server_create_channel_key.
663 * Changed the silc_server_create_channel_key to return
664 TRUE or FALSE to indicate the success of the channel key
667 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
669 * Fixed MSVC++ project files and added missing files to
670 Makefiles under win32/.
672 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Do not add TCP_NODELAY flag if the operating system
675 does not have it defined. Affected files are
676 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
678 * Fixed buffer overflow from Irssi SILC Client. Affected
679 file irssi/src/fe-common/core/themes.c.
681 * Fixed double free in client library in the file
682 lib/silcclient/client.c when disconnecting from server.
684 * Applied double free patch from cras to Irssi SILC client.
685 Affected files irssi/src/core/[modules/expandos].c
687 * Fixed the disconnection handling to Irssi SILC Client.
688 The application must call silc_client_close_connection
689 in ops->connect client operation in case of failure of
690 the connection. Affected file is
691 irssi/src/silc/core/client_ops.c.
693 * Do not set sock->protocol to NULL in the function
694 silc_client_close_connection after executing the protocol's
695 final callback since the sock might not be valid anymore.
696 Affected file lib/silcclient/client.c.
698 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Do not enable SILC_THREADS if the linking with libpthread
701 did not happen. Affected file configure.in.pre.
703 * Added notion to protocol specification that server must
704 verify the sent authentication payload with CMODE when
705 setting the channel founder key. Implemented it to the
706 server. Affected file silcd/command.c.
708 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Added _EXTRA_DIST SILC distribution variable to the
711 distributions file. It is used to conditionally add extra
712 files or directories to the specific distribution. Affected
713 files ./prepare, Makefile.am.pre and distributions.
715 Removed the `_' from the start of the distribution names.
718 * Added README.WIN32 for instructions to compile the Toolkit
721 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
723 * Fixed a double free in disconnection in the server. Affected
724 file is silcd/server.c.
726 * Fixed the lib/silcske/groups.c to work now also with GMP
727 MP library. The string conversion did not work when using
728 specific base and the base is indicated in the string as well.
730 * Created win32/ directory which now includes MSVC++ specific
731 stuff so that toolkit (DLLs) may be compiled with MSVC++.
732 It will appear only in the toolkit distribution
734 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
736 * Changed the key material distribution function in case when
737 the hash output is too short. The data is now concatenated
738 a bit differently than it used to. Made the change to the
739 SKE protocol specification.
741 * Added better GMP detection to configure.in.pre. A patch
744 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Fixed a minor bug in SKE that might cause some problem on
747 some platforms. Affected file lib/silcske/silcske.c.
749 * Added the cookie checking for initiator in the SKE. It checks
750 that the responder returns the sent cookie unmodified. The
751 affected file is lib/silcske/silcske.c. Added new SKE
752 error type INVALID_COOKIE that can be sent during the
753 negotiation. Fixed some memory leaks as well.
755 * Added the "invalid cookie" error message to Irssi SILC client's
758 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
760 * Added `task_max' field to the SilcClientParams to indicate
761 the maximum tasks the scheduler can handle. If set to zero,
762 default values are used. Affected file lib/silcclient/silcapi.h.
764 * Fixed memory leaks in silc_client_close_connection. Affected
765 file lib/silcclient/client.c.
767 * Added silc_client_del_client_entry to client library to free
768 all memory of given client entry. Affected file is
769 lib/silcclient/idlist.[ch].
771 * Added new functions silc_client_del_channel and
772 silc_client_del_server to delete channel and server entries.
773 Affected file lib/silcclient/[silcapi.h/idlist.c].
775 * Removed silc_client_del_client_by_id from silcapi.h.
777 * Fixed the INFO command to return the server's own info
778 correctly when querying by Server ID. Affected file is
781 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Removed the non-blocking settings in WIN32 code in the
784 silc_sock_[read/write] and added SleepEx instead. Affected
785 file lib/silcutil/win32/silcwin32sockconn.c. The availability
786 of input data is now checked with FIONREAD and ioctlsocket.
788 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Call silc_schedule_task_del_by_context in the
791 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
792 Affected file lib/silccore/silcprotocol.c.
794 * Call silc_protocol_cancel for active protocols in the
795 silc_server_close_connection if the funtion
796 silc_server_free_sock_user_data has not been called.
797 Affected file silcd/server.c.
799 * Generic tasks cannot be deleted using the del_by_fd
800 task deleting function since generic tasks does not match
801 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
803 * Added a notion to SILCOPER help file that the SILCOPER works
804 only on router server, not on normal server.
806 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
808 * Added for WIN32 support for the new scheduler as well.
809 Affected file lib/silcutil/win32/silcwin32schedule.c.
811 * Fixed the SHA1 implementation to work on various platforms.
813 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
816 API. It is part of the scheduler now. Everything else is
817 as previously but some functions has changed their names.
818 Checkout the lib/silcutil/silcschedule.h for the interface.
819 Updated all applications to use the new interface. Affected
820 files are lib/silcutil/silcschedule.[ch].
822 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Found a bug in the SKE implementation. The HASH value,
825 specified by the protocol, was not computed correctly. The
826 public key of the responder was not added to the computation
827 even though it is mandatory. Affected file lib/silcske/silcske.c.
828 This unfortunately causes incompatibilities with older
831 * Added WIN32 specific network init and uninit functions:
832 silc_net_win32_init and silc_net_win32_uninit to init and uninit
833 the Winsock2. Affected file lib/silcutil/silcnet.h and
834 lib/silcutil/win32/silcwin32net.c.
836 * Set the socket always to nonblocking mode on WIN32 after
837 reading data or writing data. Affected file is
838 lib/silcutil/win32/silcwin32sockconn.c.
840 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
842 * Fixed various compilation problems under WIN32. Affected
843 files lib/silcutil/win32/silcwin32thread.c and
844 lib/silcutil/win32/silcwin32schedule.c.
846 * Removed all _internal.h #includes from public header
847 files. Internal headers must never be included from
850 Removed also the lib/silcske/payload_internal.h file.
852 * All include files that may be needed (public and some others
853 included by the public headers) by application developers are
854 now copied to the ./includes directory. It does not copy any
855 internal headers. Affected file Makefile.defines.pre and all
856 Makefile.am's under lib/ and subdirs.
858 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
860 * Do not change the ~/.silc directory's permissions automatically.
861 Affected file irssi/src/silc/core/clientutil.c.
863 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Do not cancel the protocol in silc_server_close_connection
866 it might cause recursion. Now cancelled in the function
867 silc_server_free_sock_user_data. Affected file silcd/server.c.
869 * Fixed the silc_server_remove_clients_by_server to regenerate
870 the channel keys correctly finally. Added also new function
871 silc_server_remove_clients_channels to actually do it.
872 Affected file silcd/server.c.
874 * Fixed the silc_server_new_channel to not crash by giving
875 wrong router to the new channel. Affected file is
876 silcd/packet_receive.c.
878 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
881 which is given as argument to the silc_client_alloc now.
882 It can be used to configure the client and set various parameters
883 that affect the function of the client.
885 * The USERS command in server did not check whether the channel
886 is private or secret. Affected file silcd/command.c.
888 * Added new argument to the USERS command in protocol specification.
889 The USERS command now can take the channel name as argument
890 as well. Added support for this in client and server and
891 updated the protocol specs.
893 * Completed the GETKEY command in client. It can be now used
894 to fetch also servers public key not only some clients.
895 Affected files lib/silcclient/command[_reply].c.
897 * Added silc_client_get_server to return server entry by the
898 server name. Affected files lib/silcclient/silcapi.h and
901 * Redefined the IDENTIFY command in protocol specification to be
902 more generic. It now can be used to query information about
903 any entity in the SILC Network, including clients, servers and
904 channels. The query may be based either the entity's name
905 or the ID. Added support for this in both client and server.
907 Affected files silcd/command.c and lib/silcclient/command.c
910 * Optimized the WHOIS and WHOWAS commands in the server. Removed
911 the _from_client and _from_server functions. Affected file
914 * Added silc_client_get_channel_by_id_resolve to the file
915 lib/silcclient/silcapi.h to resolve channel information by
916 its ID. Added also silc_client_get_channel_by_id that
917 does not resolve it from the server.
919 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Added SilcServerEntry context into the client library
922 to represent one server. The INFO command now allocates
923 these to save the resolved server info. For now on the
924 client library will also keep information about servers,
925 connected and resolved with INFO.
927 The INFO command now allocates the SilcServerEntry context
928 and saves the server info there. The COMMAND_REPLY in
929 the INFO now returns the parameters to application in
930 same order as defined in the protocol specification.
932 The entries are cached in the client->server_cache.
934 * The INFO command is now issued after received the Client ID
935 from the server. Affected file lib/silcclient/client.c.
937 * The CMODE_CHANGE notify may now return also an SilcServerEntry
938 to the application as the mode changer might be server.
939 It is guaranteed that NULL is not returned anymore to the
940 application. Affected file lib/silcclient/client_notify.c.
942 The ID Type is now also passed to the application so that
943 it can check whether the returned entry is SilcClientEntry
946 Added new function silc_client_get_server_by_id to return
947 the server entry by ID. Affected files are the
948 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
950 * Do not create the channel in the Irssi SILC Client when issuing
951 the JOIN command but when received the sucessful JOIN command
952 reply. Otherwise the channel might get created even though we
953 could not join it. The Affected file is
954 irssi/src/silc/core/[silc-channels.c/client_ops.c].
956 * Fixed a channel joining bug in router. The router must also
957 check the channel modes, invite and ban lists etc. when serving
958 the JOIN command sent by normal server. Affected file is
959 silcd/command.c. The router now resolves the client's
960 information from the server who sent the JOIN command if it
961 does not know it, and processes the JOIN command only after
964 * Changed the SilcCommandCb to take new argument; void *context2.
965 Affected file lib/silccore/silccommand.h
967 The second argument in the command callbacks in the server now
968 includes the SilcServerCommandReplyContext if the command was
969 called as pending command callback from the command reply.
970 Otherwise it is NULL. When called as pending the status of the
971 command reply will be checked and if it was erronous the
972 error will be sent to the original sender of the command.
973 This way the client always receives the error messages even
974 though the server was actually the one who received the error
975 when it resent the command to router, for example. Affected
976 files silcd/command[_reply].[ch].
978 * Fixed sending WHOWAS command's error message to client if
979 the requested client could not be found. It was missing.
982 * Changed the CMODE and CUMODE commands reply arguments in the
983 protocol specification. The Channel ID is now sent in both
984 of the commands to identify the channel. Implemented this
985 new feature to the client and server. Affected files
986 lib/silcclient/command_reply.c and silcd/command.c.
988 * Made better checks for invite and ban lists in the JOIN
989 command in server. Affected file silcd/command.c.
991 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * The server now performs the incoming host IP/DNS lookup
994 using the silc_socket_host_lookup and thus does not block
995 the server anymore. Affected file silcd/server.c.
997 * Completed the multi-thread support for SILC Scheduler in
998 the lib/silcutil/silcschedule.c.
1000 * Fixed the configure.in.pre to detect the pthread correctly
1003 * Fixed a deadlock in silc_task_queue_wakeup in the file
1004 lib/silcutil/silctask.c.
1006 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Added new function silc_schedule_wakeup that is used in
1009 multi-threaded environment to wakeup the main thread's
1010 schduler. It needs to be used when a thread adds a new task
1011 or removes a task from task queues. After waking up, the
1012 scheduler will detect the task queue changes. If threads
1013 support is not compiled in this function has no effect.
1014 Implemented the wakeup mechanism to both Unix and WIN32
1015 systems. Affected files are lib/silcutil/silcschedule.[ch],
1016 lib/silcutil/unix/silcunixschedule.c and the
1017 lib/silcutil/win32/silcwin32schedule.c.
1019 * Added new function silc_task_queue_wakeup to wakeup the
1020 scheduler by the specified task queue. Affected file
1021 lib/silcutil/silctask.[ch].
1023 * The silc_socket_host_lookup_start now wakes up the scheduler
1024 after adding the timeout task. Affected file is
1025 lib/silcutil/silcsockconn.c.
1027 * The silc_socket_host_lookup is synchronous now if the threads
1028 support is not compiled in. However, the callback is still
1029 called asyncronously through the scheduler, anyway. Affected
1030 file lib/silcutil/silcsockconn.c.
1032 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Added new function silc_socket_host_lookup to perform
1035 asynchronous IP and FQDN lookups for the socket connection.
1036 Affected files lib/silcutil/silcsockconn.[ch].
1038 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1041 that may or may not compile the mutex support in.
1043 Changed the silc_mutex_alloc interface. It allocates the
1044 mutex now to the sent pointer and returns TRUE or FALSE.
1046 Affected file lib/silcutil/silcmutex.h.
1048 * Wrote the SILC Task Queue interface to support multi-threads.
1049 Affected file lib/silcutil/silctask.[ch].
1051 * Wrote the SILC Scheduler to support multi-threads. Affected
1052 file lib/silcutil/silcschedule.c.
1054 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1057 in lib/silcutil/win32/.
1059 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1061 * Defined SILC Mutex API and SILC Thread API and implemented
1062 them for Unix. Affected files are
1063 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1064 lib/silcutil/unix/silcunixmutex.c and
1065 lib/silcutil/unix/silcunixthread.c.
1067 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Fixed the silc_server_remove_clients_by_server's channel
1070 key re-generation. The hash table handling was incorrect
1071 and would not work with many channels. Affected file is
1074 * Fixed some memory leaks around the server code.
1076 * Rewrote the silc_server_get_users_on_channel to support IPv6
1077 based Client ID's. Affected file silcd/server.c.
1079 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1080 specification. However, a separate document must be written
1081 to define the detailed signing procedure and the payload
1082 associated with the flag. Defined the flag to the
1083 lib/silccore/silcchannel.h as well.
1085 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Changed the dynamic tables to static size tables in the
1088 lib/silccrypt/silchmac.c.
1090 * Removed GCC dependencies from the code. A patch by cras.
1092 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Do not show the error "Error receiving packet bla bla"
1095 in server if it really was not an error (-2 means that reading
1096 is pending). Affected file silcd/server.c.
1098 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Fixed a possible crash in silc_server_remove_clients_by_server
1101 in silcd/server.c. Fixed there also some memory leaks.
1103 * Fixed the silc_idlist_replace_client_id. It could replace
1104 wrong key in the hash table. Affected file silcd/idlist.c.
1106 * Do not check whether there are global users on the channel
1107 if the channel->global_users is FALSE. Affected functions
1108 silc_server_remove_from_one_channel and
1109 silc_server_remove_from_channels in silcd/server.c. Also,
1110 do not check if the removed client is local as we can be
1111 sure that global client was not removed from the channel
1112 and checking for global users is not needed.
1114 * The silc_server_remove_clients_by_server now re-generates
1115 the channel keys correctly for those channels that had
1116 clients removed from them. Affected file silcd/server.c.
1118 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1120 * Found the reason of random crashes in the server. We weren't
1121 ignoring the SIGPIPE signal (which can be sent in write())
1122 and it crashed the server. Affected file silcd/silcd.c.
1124 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1126 * Assure that sock->user_data is not NULL in the function
1127 silc_server_packet_send in silcd/packet_send.c.
1129 * Disconnect the remote connection if it could not be added
1130 to any ID lists in the server. The affected file is
1133 * Check in silc_server_packet_send[_real/dest] that the
1134 socket is not disconnecting and ignore the data if it is.
1135 Affected file silcd/packet_send.c.
1137 * Define inline to __inline on native WIN32 compilation.
1138 Affected file includes/silcwin32.h.
1140 * Added some explicit type casts for inline code since MSVC
1141 require them. Affected files lib/silcutil/silcbuffer.h,
1142 lib/trq/silcdlist.h and lib/trq/silclist.h.
1144 * Print warning in log files from now on if the packet
1145 decryption fails. Affected file silcd/server.c.
1147 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Changed the `say' client operation's interface to accept
1150 new `type' argument to indicate the type of the message sent
1151 by the library. The application may filter the library's
1152 messages according the type. The affected file is the
1153 lib/silcclient/silcapi.h.
1155 * Added two new functions to lib/silcclient/silcapi.h:
1156 silc_client_del_client and silc_client_del_client_by_id.
1157 Affected file lib/silcclient/idlist.c.
1159 * Moved the clientincludes.h from includes/ to silc/ and
1160 serverincludes.h from includes/ to silcd/.
1162 * The modes for the CMODE and CUMODE are now passed as
1163 uint32 for application with COMMAND_REPLY. The affected
1164 file is lib/silcclient/command_reply.c.
1166 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * /WHOIS without arguments shows client's own information.
1169 Affected file lib/silcclient/command.c.
1171 * Changed PING to not accept any arguments. The specs
1172 says that client can ping only the connected server so
1173 requiring an argument is not needed. Affected file is
1174 lib/silcclient/command.c.
1176 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Fixed a fatal bug in private message sending and reception
1179 encryption and decryption when using private message keys.
1180 The implementation was incorrect and did not follow the
1181 specification. It causd that some of the message were
1182 lost since it did not use the sending and receiving keys
1183 as the protocol suggests. This has been fixed and will cause
1184 incompatibilities with older clients when sending private
1185 message encrypted with private message keys. Affected files
1186 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1187 and various other in Irssi SILC Client.
1189 Added `responder' boolean argument to the functions
1190 silc_client_add_private_message_key[_ske] to indicate when
1191 the key is added as responder or initiator of the key
1194 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Removed the silc_ske_check_version function and created
1197 a SilcSKECheckVersion callback. Added also a function
1198 silc_ske_set_callbacks that is now used to set all SKE
1199 callbacks. The callback functions are not given to
1200 the SKE functions anymore, but this function is used to
1203 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1205 * Added `silc_version' argument to the silc_client_alloc
1206 to define the version of the application for the library.
1207 The library will use the version string to compare it
1208 against the remote host's (usually a server) version
1209 string. Affected file lib/silcclient/silcapi.h
1211 * Added the KE protocol context to Key Agreement context
1212 in client library so that we can abort the SKE if it
1213 is in process when we get timeout. Affected file is
1214 lib/silcclient/client_keyagr.c.
1216 * Do not resolve the client ID forever if it returns in the
1217 first time that such client does not exist. This was done
1218 for example with private message. Affected file is
1219 lib/silcclient/client_prvmsg.c.
1221 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * Do not add regex.h for WIN32. The affected file
1224 includes/silcincludes.h.
1226 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1227 not work yet 100%. It generates the DLL's automatically
1228 when compiling with --with-win32 under cygwin.
1230 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * lib/contrib/regex.c is not compiled on WIN32.
1234 * Added silc_net_get_socket_opt function to the
1235 lib/silcutil/silcnet.h.
1237 * Added includes/silcwin32.h for WIN32 specific includes
1240 * Do not use ptime structure or any of the posix process
1241 functions on WIN32 in lib/silccrypt/silrng.c.
1243 * Added silc_gettimeofday to provide generic function
1244 for struct timeval on all platforms. Added the function
1245 to lib/silcutil/silcutil.h.
1247 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1250 library as they clearly belong there. As a plus side we
1251 can make the actual socket connection routines platform
1254 Added also new generic function silc_socket_read and
1255 silc_socket_write (that used to be silc_packet_[read/write].
1256 The implementation of these are platform specific.
1258 * Added WIN32 specific routines of silc_socket_[read/write]
1259 to lib/silcutil/win32/silcwin32sockconn.c.
1261 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Added preliminary support for native WIN32 compilation under
1264 cygwin (using the -mno-cygwin option for GCC) to the
1265 ./configure.in.pre. The --with-win32 now prepares the
1266 compilation for native WIN32.
1268 * Rewrote the SILC Scheduler interface in the file
1269 lib/silcutil/silcschedule.h. The scheduler is now context
1270 based and does not have anymore any global static scheduler.
1271 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1272 and created lib/silcutil/win32 directory for WIN32 based
1275 * Added Unix specific network routines to the
1276 lib/silcutil/unix/silcunixnet.c and the old
1277 lib/silcutil/silcnet.c includes now only generic routines.
1279 Added WIN32 specific network routines to the
1280 lib/silcutil/win32/silcwin32net.c.
1282 * Added Unix specific utility functions from the
1283 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1285 * Added WIN32 SILC Scheduler to the file
1286 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1289 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * Do not handle JOIN notify in the server if the target client
1292 is not registered (idata->registered == FALSE). The affected
1293 file is silcd/packet_receive.c.
1295 * Update the nickrec->founder in event_cumode in the Irssi SILC
1296 client. Affected file irssi/src/silc/core/silc-channels.c.
1298 * Fixed the CUMODE_CHANGE notify handling in the server when
1299 server and router are announcing their clients on channels.
1300 Now the mode changes are saved and notified correctly. The
1301 affected file is /silcd/packet_receive.c.
1303 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1304 They really did not replace the cache entry in the ID Cache.
1305 Now they do that. Affected file silcd/idlist.c.
1307 * Fixed the KICK notify handling in the Irssi SILC client to
1308 update the channel records so that the kicked client does not
1309 appear to be on the channel. The affected file is
1310 irssi/src/silc/core/silc-channels.c.
1312 * Always update the conn->current_channel when executing command
1313 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1315 * Fixed the KILL notify handling in Irssi SILC client to remove
1316 the killed client on all channels.
1318 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1320 * Fixed the silc_parse_command_line to remove extra spaces
1321 from the start and end of the arguments. Affected file is
1322 lib/silcutil/silcutil.c.
1324 * Cancel and free any active protocol in the function
1325 silc_server_close_connection. Affected file silcd/server.c.
1327 * Cancel and free any active protocol in the function
1328 silc_client_close_connction. Affected file is
1329 lib/silcclient/client.c.
1331 * Do not execute the KILL command for clients that are in
1332 history (ie. they are not in the network). Affected file is
1335 * Fixed KILL notify handling, client does not crash anymore.
1336 Affected file irssi/src/silc/core/silc-channels.c.
1338 * Reduced the default packet buffer size from 2048 to 1024 in
1339 lib/silccore/silcpacket.c.
1341 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1342 counter to the SKE context that is incresed when the SKE library
1343 performs async operation outside the library. If the outside
1344 process frees the SKE context and FREED status will be set
1345 and the library will detect after the sync operation that the
1346 libary is freed. The affected files are
1347 lib/silcske/silcske[_status].[ch].
1349 * Resolve the client entry information in the function
1350 silc_client_channel_message to assure that NULL pointer is not
1351 passed as client entry to the application. */
1353 * Fixed the task timeout calculation to assure that there is
1354 never negative timeouts. The affected file is
1355 lib/silcutil/silcschedule.c.
1357 * Fixed the channel user mode notification sending in server.
1358 It was sent point-to-point to the router (or to server by router)
1359 but it needs to be destined to a channel. The routines now
1360 supports sending the channel user mode notifys to the channels
1361 when announcing clients and channels. Affected files are
1362 silcd/server.c and silcd/packet_receive.c.
1364 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1365 It did not actually replace the old channel entry in the cache.
1366 Affected file lib/silcclient/client_notify.c.
1368 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1370 * Fixed a possible crash in silc_packet_send_prepare. It now
1371 assures always that there is enough space in the buffer and
1372 at the tail area of the buffer (for MAC).
1374 Fixed the inbound buffer reallocation in silc_packet_read.
1375 It was old code and did not handle the reallocation correctly.
1378 The affected file is lib/silccore/silcpacket.c.
1380 * Fixed buffer overflow in silc_parse_nickname in the file
1381 lib/silcutil/silcutil.c.
1383 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * make install generates new server keys only if there is not
1388 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1391 Added check that if the NOREPLY is set then we will not send
1392 the away message. This avoids infinite loop of away messages
1393 if both clients are away. The affected file is
1394 lib/silcclient/client_prvmsg.c.
1396 * Fixed client crash if /NICK was given without arguments.
1397 Affected file lib/silcclient/command.c.
1399 * Server does not send the invite list in INVITE command back
1400 to the client if the list was not altered. Added this notion
1401 to the protocol spec as well. Affected file silcd/command.c.
1403 Fixed possible crash in INVITE command by checking the
1404 value of silc_server_get_client_route command.
1406 * Fixed the INVITE notify type handling. The arguments are now
1407 taken in correct order and client does not crash. The affected
1408 file is irssi/src/silc/core/silc-channels.c.
1410 Removed the "Inviting xxx to channel" message from the
1411 client library away and let the application handle it.
1412 Affected file lib/silcclient/command.c. Added that message
1413 to Irssi SILC client's message formats.
1415 * Fixed CMODE command crash in client. It now checks the
1416 amount of arguments correctly and does not crash. The affected
1417 file is lib/silcclient/command.c.
1419 * Do not create new channel automatically in silc_channels_join
1420 but check whether the channel by that name already exists.
1421 Affected file irssi/silc/core/silc-channels.c.
1423 * Do not send the SERVER_SIGNOFF to router if the disconnected
1424 entity was the router. Affected file silcd/server.c.
1426 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1427 SILC client as it was missing from there.
1429 Added the handling of the KICK notify to the Irssi SILC client
1430 as it was missing. Added "you have been kicked" message to
1431 Irssi SILC client's message modules formats.
1433 Added the handing of the KILL notify to the Irssi SILC client
1434 as it was missing. Added the kill message module formats
1437 The affected file is irssi/src/silc/core/silc-channels.c.
1439 * The router did not save the channel mode the server announced.
1440 Affected file silcd/packet_receive.c.
1442 * Fixed a possible crash in INFO command in server. If the
1443 server did not provide the server info it crashed. Affected
1444 file silcd/command.c.
1446 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1448 * Fixed the GETKEY command in the server to check also the
1449 global list. Otherwise the GETKEY would not work correctly
1450 in normal SILC server. Affected file silcd/command.c.
1452 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Fixed GETKEY crash, it crashed if the command did not succseed.
1456 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1458 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1459 is now real and not just an macro interface to GMP.
1461 Removed the entire GMP from the source tree and imported new
1462 NSS MPI library instead. Reason for removing GMP is that it is
1463 extremely large and compiles extremely slow. The NSS MPI
1464 is only a few files and compiles in less than 10 seconds.
1465 The speed is also about the same as GMP. The MPI is imported
1466 to lib/silcmath/mpi.
1468 If the system has GMP installed we will still use the GMP.
1469 If it is not then the NSS MPI will be compiled.
1471 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Merged a long nickname (127 characters long) crash bugfix from
1474 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1476 * Merged a freed memory reference bugfix from Irssi CVS tree.
1477 Affected file irssi/src/core/commands.c.
1479 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * Added the server's public key sving and verification to the
1482 server when performing the SKE. This was missing and the
1483 remote server's (or router's) public key was accepted without
1484 checking whether we have it previously or trust it at all.
1485 Affected file silcd/protocol.c.
1487 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1489 * Check in the silc_server_timeout_remote if protocol is active
1490 and make sure that the protocol's final callback is called so
1491 that all memory if freed. Affected file silcd/server.c.
1493 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1495 * silc_server_whois_send_reply crashed the server if the nickname
1496 was 127 characters long. Affected file silcd/command.c.
1498 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Added sanity check to the silc_server_new_client. If the hostname
1501 is provided inside username then check that the provided hostname
1502 really is the same as the resolved one. If the hostname was not
1503 resolved then check it from the public key. Affected file is
1504 silcd/packet_receive.c.
1506 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1507 if the server disconnected us and the connection is not valid
1508 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1510 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1511 the library to the lib/silcutil/silcutil.[ch].
1513 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1515 * Close log file after open. Affected file
1516 lib/silcutil/silclog.c.
1518 * Check whether sock == NULL in silc_client_send_packet and return
1519 if it is. Affected file lib/silcclient/silcclient.c.
1521 * Check rec->entry == NULL in the Irssi SILC Client before
1522 sending the channel message. Affecte file is
1523 irssi/src/silc/core/silc-servers.c.
1525 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Merged a splitted window bugfix from Irssi CVS tree. The
1528 affected file is irssi/src/fe-text/textbuffer-view.c.
1530 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1531 It did not print nickname.
1533 * Improved the distributions system a bit.
1535 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1538 irssi/src/fe-text/gui-window.c.
1540 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1541 to in-active server. The affected file is
1542 irssi/src/silc/core/client_ops.c.
1544 * Resolve the client in USERS command reply if the entry does
1545 not have username resolved. The affected file is
1546 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1547 command to WHOIS command to really resolve stuff. The USERS
1548 is not used any more in any critical section so WHOIS can
1549 be used even though it might be slower than IDENTIFY.
1551 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1554 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Changed the protocol API a bit more consistent in the
1557 lib/silccore/silcprotocol.[ch].
1559 * Changed the following headers to ROBODoc format:
1561 lib/silccore/silcpayload.h
1562 lib/silccore/silcprotocol.h
1563 lib/silccore/silcsockconn.h
1565 All core library headers are now formatted.
1567 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Fixed a bug in Irssi SILC client; do not show that you are
1570 server/router operator if you really are not. Affected file is
1571 irssi/src/silc/core/client_ops.c.
1573 * Renamed silc_command_free_payload to silc_command_payload_free.
1574 Affected file lib/silccore/silccommand.h
1576 * Added silcmath.h to include the prototoypes of various routines
1577 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1580 * Changed the following headers to ROBODoc format:
1582 lib/silccore/silcchannel.h
1583 lib/silccore/silccommand.h
1584 lib/silccore/silcid.h
1585 lib/silccore/silcidcache.h
1586 lib/silccore/silcmode.h
1587 lib/silccore/silcnotify.h
1588 lib/silccore/silcpacket.h
1589 lib/silcmath/silcmath.h
1591 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Added checking to the server code not to start the server if
1594 ciphers and stuff are not configured properly. Affected files
1595 silcd/serverconfig.[h] and silcd/server.c.
1597 * Changed the layout of the header files of the public interfaces
1598 in the SILC libraries. The new layout supports ROBODoc
1599 documentation tool (and some others) so that it is easy to create
1600 a library reference manual. All the other headers and source
1601 code must still follow the CodingStyle document. Also source
1602 code must not include these ROBODoc stuffs, only the headers.
1603 Furthermore, all public interface headers must now be named
1604 by using `silc' prefix, example: silcapi.h, silccipher.h.
1605 Some files were renamed due to this. All the other headers
1606 must not be used as public interfaces. I will update the
1607 CodingStyle document later. Changed following headers, so far:
1609 lib/silcclient/silcapi.h
1610 lib/silccore/silcauth.h
1611 lib/silccore/silcprivate.h
1612 lib/silccrypt/silcdh.h
1614 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Removed silc_client_packet_send_flush from the client library
1619 as it is not needed. Affected file lib/silcclient/client.[ch].
1621 * Added printing of message of unresolved authentication method
1622 to the Irssi SILC client. Added it to the module formats.
1623 Removed the same message from the client library.
1625 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1627 * Added new distribution feature, DISTLABEL. Every distribution
1628 can define own preprocessor label that can be used in the
1629 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1630 file distributions, acconfig.h.pre and prepare.
1632 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1634 * Added Makefile.defines_int to include the actual definitions
1635 for Makefile.defines.in. Tested the new distribution system,
1636 created distributions and tested installation.
1638 * Added AWAY message printing to the Irssi SILC client. Added
1639 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1641 * Added SCONNECT command to call the SILC's CONNECT command.
1642 Cannot use CONNECT directly since Irssi uses that internally.
1643 Affected file irssi/src/silc/core/silc-servers.c.
1645 Added ACTION local command. It is same as ME command but takes
1646 the channel as mandatory argument.
1648 Rewrote some of the Irssi's help files to suite for SILC
1651 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Added Makefile.defines[.in] that should for now on be included
1654 in all Makefile.am file in the source tree. That file includes
1655 all common compilation definitions for SILC source tree.
1657 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1659 * Minor changes to the ./prepare script to change the package
1660 name according the distribution name to the configure.in.
1662 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Created new distribution system. Added file `distributions'
1665 that defines all the distributions that can be created out of
1666 the SILC source tree. The ./prepare script now reads that
1667 file to determine how to prepare the distributions. The
1668 first argument to the ./prepare is the name of the distribution
1669 and second is the version of the distribution. If given
1670 without arguments it creates the default (toolkit) distribution
1671 with the default version (defined in ./prepare).
1673 All Makefile.am files that are subject to the distributions
1674 are now named as Makefile.am.pre. These are ./Makefile.am
1675 and lib/Makefile.am. Others may be changed later.
1677 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1679 * Added invite list, ban list, some key management and connection
1680 error message printing to module formats in the Irssi SILC client.
1682 * Added new silc_client_set_away_message to set the away message
1683 that is back to the person who sent private message. The
1684 affected file lib/silcclient/silcapi.h and the
1685 lib/silcclient/client_prvmsg.c.
1687 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * Fixed the private message sending in the Irssi SILC client,
1690 added local command KEY to the Irssi SILC client.
1692 Added key management and key agreement message formats to the
1693 irssi/src/fe-common/silc/module-formats.[ch].
1695 Added USERS (alias WHO) printing, server/router operator
1696 indication and LIST command printing to the module formats.
1698 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Fixed channel joining notify handling, cumode notify handling
1701 from Irssi SILC client.
1703 * Added SILC specific module-formats to the Irssi SILC client so
1704 that SILC specific message hilighting, colors etc is possible.
1705 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1707 Added channel mode, channel user mode, actions, notices,
1708 whois and whowas printing to the the module-formats.c.
1710 * Fixed a bug in channel deletion in the server. The channel
1711 is not left to the cache even if the channel founder auth mode
1712 is set when there are no users anymore on the channel. Affected
1713 file silcd/server.c.
1715 * The silc_net_localhost now resolves the entire hostname including
1716 the domain name. Affected file lib/silcutil/silcnet.c.
1718 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Changed the ask_passphrase client operation to be ascynchronous.
1721 It has now a completion callback and a context that the
1722 application must call after it has got the passphrase from
1723 the user. Affected files lib/silcclient/silcapi.h,
1724 lib/silcclient/protocol.c, lib/silcclient/command.c and
1727 Added SilcAskPassphrase callback that the application calls
1728 to deliver the passphrase to the library.
1730 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1731 The public key verification and especially a certificate
1732 verification is asynchronous procedure.
1734 Added new SILC_SKE_STATUS_PENDING status to indicate the
1735 request is pending and a callback will be called to finalize
1738 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1739 indicate that remote end did not send its public key (or
1740 certificate), even though we require it. Added check for this
1741 condition in the SKE. This was a security bug, now fixed.
1743 Defined new SilcSKEVerifyCbCompletion callback that is called
1744 when the verification process is completed.
1746 The affected files lib/silcske/silcske_status.h and
1747 lib/silcske/silcske.[ch].
1749 * Changed the verify_public_key client operation to be async
1750 as well. Defined SilcVerifyPublicKey callback that is used to
1751 indicate the success of the public key verification process.
1753 Changed the server and client to use the new async client
1756 * Changed the Irssi SILC client's internal scheduler to be called
1757 twice as many times as it used to be. As a result the client
1758 should be a bit faster now. Affected file is
1759 irssi/src/silc/core/silc-core.c.
1761 * Added support to Irssi SILC client of asynchronous public key
1762 verification and passphrase inquiry. Affected file is
1763 irssi/src/silc/core/silc-core.c.
1765 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Do not say "You have left channel %s" in client library.
1768 Moved it to the application. Affected files are
1769 lib/silcclient/command.c and silc/client_ops.c.
1771 * Fixed silc_client_get_clients. Command context was not
1772 duplicated and was freed memory in the callback. Affected
1773 file lib/silcclient/idlist.c.
1775 * Do not say "you are now talking..." on JOIN command in the
1776 client library. The appliation must handle it.
1778 * Do not say ".. changed topic to" in command reply in the
1779 client libary. The application must handle it.
1781 * Fixed TOPIC command sending in the client library.
1783 * Fixed a memory leak in silc_client_command_free in the file
1784 lib/silcclient/command.c.
1786 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Imported a modified version of Irssi client to the source tree.
1789 The Irssi will be used to create a new client called
1790 Irssi SILC. Imported to irssi/.
1792 Added silc_core_init_finish function to the Irssi. Affected
1793 file irssi/configure.in.
1795 A lot changes in the Makefile.ams around the irssi tree.
1797 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Do not rehash if the new size is same as the old size of the
1800 hash table, in the silc_hash_table_rehash*. The affected file
1801 lib/silcutil/silchashtable.c.
1803 * Replaced hash_table_del_by_context calls from the server
1804 (when channel->user_list and client->channels) to the
1805 hash_table_del as it is sufficient and faster.
1807 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1809 * Added silc_hash_table_list, silc_hash_table_get and the
1810 SilcHashTableList structure to provide an alternative way to
1811 traverse the hash table. The affected files are
1812 lib/silcutil/silchashtable.[ch].
1814 * Changed the server's idlist routines to use the hash table
1815 routines to optimize the code.
1817 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Replaced the client entry's `channel' list and channel entry's
1820 `user_list' list to hash tables for optimized lookup. Changed
1821 the code to use the hash table interface around the code.
1822 Affected file lib/silcd/idlist.[ch].
1824 * Added `auto_rehash' boolean argument to the function
1825 silc_hash_table_alloc to indicate whether the hash table should
1826 auto-rehash when it thinks is appropriate time. It will
1827 increase the hash table size if the there is twice as much
1828 entries in the table than the size of the table, and will
1829 decrease the size if there are twice as less entries than
1830 the size of the table.
1832 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1836 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * silc_idcache_purge_by_context deletes the entry now by context
1839 as it is supposed to do. Affected file lib/silccore/idcache.c.
1841 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1842 client is not anymore valid (WHOWAS givens the info) and not
1843 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1845 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * Removed the `data' and `data_len' arguments from the ID Cache
1848 interfaces and added `name' argument. ID Cache does not handle
1849 anymore the binary data only a names associated with given ID.
1851 * When hashing a Client ID with silc_hash_id the entire ID is
1852 not hashed anymore, instead only the hash of the Client ID is
1853 hashed. This way we can access the Client ID from the cache
1854 with Client ID but with the hash of the ID (which is a hash of
1855 the nickname) as well without any difference in performance.
1857 Added also silc_idcache_find_by_id_one_ext to do one on one
1858 searching when we have the actual ID. Added also function
1859 silc_hash_client_id_compare. The affected files are
1860 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1862 * When hashing the name associated with a ID it is always done
1863 in lowercase. This way we can access the cache without worrying
1864 about case-sensitivity, even though, for example nicknames are
1867 * Fixed a bug in server with channel message sending. It put
1868 wrong ID type as destination ID. The affected file
1869 silcd/packet_send.c.
1871 * silc_idcache_del_by_context now deletes from all hash tables
1872 by context. Affected file lib/silccore/idcache.c.
1874 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Changed the client library to use the new ID Cache interface.
1877 Changes around the source tree.
1879 * Added silc_hash_table_rehash_ext to rehash with specific
1880 hash function. Affected file lib/silcutil/silchashtable.[ch].
1882 * Added silc_hash_string_compare to compare two strings in the
1883 hash table. Affected file lib/silcutil/silcutil.[ch].
1885 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Added new function silc_idcache_del_by_context into the
1888 lib/silccore/idcache.[ch].
1890 * Changed the server's ID list routines to use the new ID Cache
1891 interface. Changes around the source tree.
1893 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Added silc_hash_table_del[_by_context]_ext functions in to the
1896 lib/silcutil/silchashtable.[ch].
1898 Removed silc_hash_table_find_all* routines and added new
1899 silc_hash_table_find_foreach to replace them.
1901 Added silc_hash_table_replace_ext function as extended
1902 replacing function. Separated the simple hash table interface
1903 from the extended hash table interface in the file
1904 lib/silcutil/silchashtable.h.
1906 * Fixed minor bugs and changed it to use some of the new
1907 hash table functions in lib/silccore/idcache.c
1909 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Added new function silc_hash_table_find_all to return all keys
1912 in the hash table by the specified key. As the hash table is
1913 collision resistant it also makes it possible to have several
1914 duplicate keys in the hash table. This function may be used to
1915 find all of the keys from the hash.
1917 Added user_context arguments to the SilcHashFunction,
1918 SilcHashCompare and SilcHashDestructor to deliver user specified
1921 Added new fuctions silc_hash_table_find[_all]_ext to do
1922 extended lookup with specified hash and compare functions and
1923 specified user contexts.
1925 Added new function silc_hash_table_add_ext to add the key
1926 with specified hash function and user context.
1928 Added new function silc_hash_table_foreach to traverse all
1929 entrys in the hash table. Added SilcHashForeach callback
1932 Added new function silc_hash_table_del_by_context to delete
1933 the entry only if the context associated with the key matches.
1935 Affected files are lib/silcutil/silchashtable.[ch].
1937 * Removed silc_hash_[server/client/channel]_id and added just
1938 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1939 silc_hash_id_compare to compare two ID's using as the hash table
1940 comparison function. Added also silc_hash_data to hash
1941 binary data and silc_hash_data_compare to compare it.
1943 * Removed silc_idlist_find_client_by_hash as it is not needed
1944 anymore. Affected file silcd/idlist.[ch].
1946 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1947 to use internally the SilcHashTable. The new ID Cache is a lot
1948 faster than the old one. Some of the ID Cache interface was also
1949 rewritten and obsolete and stupid functions were removed.
1951 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1953 * Added entry_count field to the SilcHashTable to keep the number
1954 of the entries in the table. Implemented the function
1955 silc_hash_table_rehash. Added new function
1956 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1958 Fixed a minor bug in silc_hash_table_free.
1960 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1961 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1962 into the lib/silcutil/silcutil.[ch].
1964 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1966 * Implemented a collision resistant hash table into the
1967 lib/silcutil/silchashtable[ch]. See the header and the source
1968 for the SilcHashTable API.
1970 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Merged dotconf version 1.0.2 into lib/dotconf.
1974 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Do not compile anything in lib/silcsim/* if the SIM support
1977 is not enabled. The tree should now compile without problems
1980 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Compiled the SILC under cygwin. Compiled and tested briefly
1983 without problems. More tests needed. The SIMs didn't compile
1986 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1988 * Fixed possible crash in silc_get_username in the
1989 lib/silcutil/silcutil.c.
1991 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Fixed a va_arg in silc/client_ops.c.
1995 * Oops, RC5 routines were named AES and caused some problems
1996 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1998 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Added new SilcIDIP structure into the lib/silccore/id.h and
2001 replaced the old `ip' fields from all SILC ID's to that type.
2002 This is a step towards IPv6 support.
2004 The silc_id_get_len takes now the ID as an extra argument.
2005 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2006 both IPv4 and IPv6 based ID's.
2008 The affected files are lib/silccore/id.[ch] and other files
2009 around the tree using these routines.
2011 * Removed the ID length arguments in server from various
2012 silc_server_send_notify_* routines -> they are not needed
2015 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Fixed memory leak in silc_encode_pem_file in the file
2018 lib/silcutil/silcutil.c.
2020 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Check minor version as well in the SKE. Affected files are
2023 silcd/protocol.c and lib/silcclient/protocol.c.
2025 * Added --identifier option to the server so that an identifier
2026 can be when creating the public key for the server. Affected
2027 file is silcd/silcd.c.
2029 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2030 lib/silccrypt/silcpkcs.c.
2032 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Register default ciphers and stuff when using -C option with
2035 the server. Affected file sildc/silcd.c.
2037 * Put back the servers public key filename format, it is better
2038 than the new one. For now, the client keys are saved with the
2039 new filename format. The affected file silc/client_ops.c.
2041 * Implemented the Cipher API for the rest of the ciphers that
2042 did not implement it or implemented it the wrong way.
2044 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Register default ciphers and stuff when using the -S option
2047 in the client. Affected file silc/silc.c. Same also when
2048 creating new key pair with -C option.
2050 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Fixed the silc_verify_public_key client operation function to
2053 save the public keys differently. The fingerprint is now
2054 used as filename and not the hostname. This way also the
2055 client keys are saved uniquely and not with hostnames. The
2056 affected file is silc/client_ops.c.
2058 * Trimmed the silc_hash_fingerprint function to remove extra
2059 whitespaces from the end of the fingerprint. The affected
2060 file is lib/silccrypt/silchash.c.
2064 * Added silc_cipher_register_default function to register all
2065 default ciphers. It can be used when configuration files
2066 does not exist and the application does not want any specific
2067 ciphers in any specific order.
2069 The SilcDList is now used as silc_cipher_list dynamically
2070 allocated cipher list. Removed the static list all together
2071 and now all ciphers must be allocated to the dynamic list.
2072 The silc_cipher_alloc routine was changed to check only the
2075 All silc_cipher_* routines that used to return int returns
2078 The affected files lib/silccrypt/silccrypt.[ch].
2080 * The same thing was done to silc_hash_* as for silc_cipher_*
2081 routines. Affected files lib/silccrypt/silchash.[ch].
2083 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2084 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2085 Added also silc_pkcs_[un]register[_default] functions.
2086 Removed the data_context from the PKCS API.
2088 * Added silc_hmac_register_default function to register default
2089 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2090 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2091 to unregister all hmacs at once.
2093 * Register the default ciphers, hash functions, PKCSs and HMACs
2094 if client's configuration file does not exist. The affected
2097 * The client did not load the hash functions from the SIM
2098 modules at all. Added support for this. Affected file is
2099 silc/clientconfig.c.
2101 * When decoding public key with silc_pkcs_public_key_decode, check
2102 the supported algorithm only if PKCS are registered. Affected
2103 file lib/silccrypt/silcpkcs.c. The same was done with the
2104 silc_pkcs_private_key_decode.
2106 * Fixed the SILC List routines to keep the list always in order.
2107 It used to change the list's order when traversing the list but
2108 not it preserves the order. Affected file lib/trq/silclist.h.
2110 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added the client library to use the SilcSocketConnection's
2113 reference counter (by silc_socket_dup) to prevent the bug that
2114 the socket object may be freed underneath async operation.
2116 * The name resolv library checking fixes in the configure.in.pre.
2119 * Created new version of the protocol drafts for future
2120 development. The -03 drafts are the ones that will be changed
2121 in the trunk now and the -02 will remain as they are.
2123 * Send list of CUMODE notifys to the router when announcing
2124 the channel users to the router. Affected file silcd/server.c.
2125 If the router receiving channel founder CUMODE for a channel
2126 that already has channel founder it will send CUMODE notify
2127 to the sender to remove the channel founder rights from the
2128 announced client. Affected file silcd/packet_receive.c.
2130 * The CUMODE notify may now use Server ID as well as the entity
2131 who changes the mode. Updated protocool specs.
2133 * Updated INSTALL and README files.
2135 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2137 * New web pages in the http://silc.pspt.fi. The pages was
2142 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Implemented the [DenyConnectin] config section in the server.
2145 Added silc_server_config_denied_conn to check whether incoming
2146 connection is denied. Affected file silcd/serverconfig.[ch].
2148 * Do not check the ports when checking the incoming configuration
2149 data if the port is 0, meaning any. Affected file is
2150 silcd/serverconfig.c.
2152 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Fixed buffer overflow in silc_string_compare in the file
2155 lib/silcutil/silcutil.c.
2157 * Fixed double free in silc_server_command_leave in the file
2160 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * Fixed the version checking in the server. Affected file is
2165 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Fixed the configuration data fetching when accepting new
2168 connections in the server. Affected file silcd/server.c.
2170 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Added `sender_entry' argument to the function
2173 silc_server_packet_relay_to_channel so that we can check
2174 whether some destination actually belongs to the same route
2175 the sender belongs (ie, we must not resend the packet to the
2176 sender). Affected file silcd/packet_send.[ch].
2178 * Added `servername' field to the SilcClientEntry in the server
2179 to hold the name of the server where client is from. Affected
2180 file is silcd/idlist.h.
2182 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Moved the channel message encrypting in the router betwen
2185 router connections from silc_server_channel_message to the
2186 silc_server_packet_relay_to_channel since we want to check
2187 whether we have anybody channel before encrypting anything.
2188 Affected files silcd/packet_[receive/send].c.
2190 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Fixed the [AdminConnection] server config section to support
2193 multiple entries. Affected file silcd/serverconfig.c.
2195 * Added support into the server to check the validity of the
2196 incoming connection before executing any KE or authentication
2199 * The connection configuration is now saved to the KE and
2200 connection auth protocol contexts and not fetched anymore in
2201 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2203 * The local hosts listenning address and port is also resolved
2204 now when starting the server. We want to have the socket object
2205 to include the real address and port for the listener. Added
2206 new function silc_net_check_local_by_sock into the files
2207 lib/silcutil/silcnet.[ch].
2209 * Fixed a broadcast bug in server -> do not broadcast if we
2212 * Fixed a routing bug. Do not route broadcast packets ever.
2213 Broadcast packets must be processed always and not routed since
2214 they may be destined to some other host than yourself and thus
2215 would get routed without no good reason. Affected file is
2218 * Added function silc_server_config_is_primary_route to check
2219 whether primary router connection has been configured (a router
2220 configuration that we are initiating). If there is not, we
2221 will assume that there is only two routers in the SILC network
2222 and we will use the incoming router connection as our primary
2223 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2225 * Changed the order of the broadcasting. Broadcast _after_ the
2226 packet has been processed not before. Affected file is
2229 * Fixed a [ClientConnection] parsing bug. The port was never
2230 parsed correctly thus resulting to port 0. Affected file
2231 silcd/serverconfig.c.
2233 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2234 argument and did not set the broadcast packet flag. Affected
2235 file silcd/packet_send.c. Fixed same bug in the function
2236 silc_server_send_notify as well.
2238 * If we receive NEW_ID packet for our own ID in the server, ignore
2241 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Removed the nickname from the Private Message Payload.
2246 Updated the code and the protocol specs.
2248 * Updated protocol specs for submitting to the IETF.
2250 * Tweaked the Random Number Generator a bit. Affected file
2251 lib/silccrypt/silcrng.c. Exported a new function
2252 silc_rng_[global]_add_noise which can be used to add more
2255 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Do not parse packets with different timeout when protocol
2258 is active -> may cause problem with rekey. Affected file
2261 * When server receives signoff notify it must not create
2262 new channel key if the client is on any channels since the
2263 sender of the signoff notify will create it.
2265 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2267 * Added printing of error messages during SKE protocol from the
2268 failure packet sent by server during SKE. Affected file
2271 * Removed the client's failure_callback handling with timeout
2272 and handle it immediately when received.
2274 * The SKE library returned wrong type in SUCCESS and FAILURE
2275 packets. They must be 32 bit MSB not 16 bit MSB.
2277 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Ok, rewrote the logic of the re-key and now it seems to work.
2280 I tested it on high traffic with frequent re-keys without
2281 problems. Added hmac_receive (and renamed hmac to hmac_send)
2282 in SilcClientConnection in lib/silcclient/client.h and
2283 in SilcIDListData in silcd/idlist.h. Also, removed the
2284 SilcPacketParserContext's cipher and hmac fields as they are
2285 not needed anymore and actually caused some problems when
2286 the ciphers and hmac's changed underneath the packet parser.
2288 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * If re-key protocol is active then process the incoming packets
2291 synchronously since we must assure that icoming packets encrypted
2292 with the old key is processed before the new keys is set to
2293 use. This is true other packets than for REKEY packets.
2294 Affected file silcd/server.c. The same was done to client library
2295 as well, affected file lib/silcclient/client.c.
2297 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Fixed bug in client and server to accept the force send if
2300 the packet is send from silc_[server/client]_packet_process
2301 function. Otherwise the packets are never delivered, oops.
2303 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Disable force sending of packets when REKEY protocol is active.
2306 We must assure that no packet is sent directly when rekey is
2307 performed. All packets must be sent through packet queue.
2308 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2309 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2310 function is silc_[server/client]_packet_send_real to check
2313 * Replaced the SIM paths from example config files to
2314 /usr/local/modules. Also, make install creates now
2315 /usr/local/silc/logs directory to hold all the SILC server
2318 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Made the configure.in.pre work on Solaris. Patch by salo.
2322 * Made all ciphers compatible with non-x86 machines. Defined
2323 CBC mode macros into lib/silccrypt/ciphers_def.h.
2325 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Fixed the make install.
2329 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * When MAC computation fails the silc_packet_decrypt returned 0
2332 even though it was supposed to return -1. Fixed this. The
2333 affected file is lib/silccore/silcpacket.c.
2335 * Do not replace the config files in /etc/silc (in make install)
2336 if they already exist. Affected file ./Makefile.am.
2338 * Do not send re-key packets immediately but through packet queue.
2339 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2341 * Changed silc_net_check_host_by_sock to return FALSE if the
2342 IP/DNS could not be resolved. Though, it returns the IP address
2343 now even if it could not resolve it (but returns also FALSE).
2344 Affected file lib/silcutil/silcnet.[ch].
2346 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Added silc_pkcs_decode_identifier to decode the public key's
2349 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2350 Added also silc_pkcs_free_identifier. Added also new context
2351 SilcPublicKeyIdentifier.
2353 * Added -S option to the silc client. It is used to dump the
2354 contents of the specified public key file.
2356 * Changed the PKCS api to return the public key length when
2357 setting the public key.
2359 * Fixed a fatal bug in the public and private key file loading.
2360 Affected file lib/silccrypt/silcpkcs.c.
2362 * Execute the packet parsing for client with zero (0) timeout
2363 if the protocol is active. Affected file silcd/server.c.
2365 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Made the key generation options to the silcd program. Added
2368 -C option, equivalent to client's option.
2370 * Added new [ServerKeys] config section to the server. It
2371 configures the server's public and private key.
2373 * Defined generic Public Key Payload into the protocol
2374 specification to send specific type of public keys and
2377 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2378 public key or certificate.
2380 * Implemented the GETKEY command to the server and to the
2381 client library and on user interface.
2383 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Made preliminary `make install' work.
2387 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Added SilcServerRekey context into silcd/idlist.h.
2391 * Added the PFS support as defined in the specification to the
2392 SKE protocol. Affected files lib/silcske/*.c.
2394 * Added `ske_group' field to the SilcServerRekey context to hold
2395 the number of the SKE group that is used with PFS in re-key.
2396 Affected file silcd/idlist.h.
2398 * Added PFS re-key support to the server. Affected file is
2401 * Added silc_protocol_cancel to cancel execution of the next
2402 state of the protocol. Affected file is
2403 lib/silccore/silcprotocol.[ch].
2405 * Added the re-key support with and without PFS to the client
2406 library. Re-key is performed once in an hour, by default.
2408 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2409 Added silc_client_rekey_callback and silc_client_rekey_final.
2410 Affected files are lib/silcclient/protocol.[ch] and
2411 lib/silcclient/client.[ch].
2413 * Removed the `hmac_key' and `hmac_key_len' fields from the
2414 SilcClientConnection structure; not needed. Affected file is
2415 lib/silcclient/client.h.
2419 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Do not ask whether user wants to use the negotiated private key
2422 for private messages, just use it. Affected file is
2423 silc/local_command.c.
2425 * Added `send_enc_key' and `enc_key_len' fields to the
2426 SilcIDListData structure since they are needed in the re-key
2427 phase. Affected file is silcd/idlist.[ch].
2429 * Implemented the simple re-key protocol into the server.
2430 Affected files silcd/server.c and silcd/protocol.[ch]. The
2431 re-key will be performed once in an hour, by default.
2433 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2434 Added silc_server_rekey, silc_server_rekey_callback and
2435 silc_server_rekey_final.
2437 * Removed Tunneled flag from the protocol. Updated the code
2438 and the specifications.
2440 * Adde `pfs' field to the SilcIDListData to indicate whether
2441 the PFS is to be performed in the re-key. Affected file is
2444 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2447 int64 of at least the xintXX size. If void * is less that 4
2448 bytes uint32 * will be used. Defined bool as boolean.
2450 * Changed _ALL_ unsigned long and unsigned int to uint32,
2451 unsgined short to uint16 in the source tree.
2453 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2454 not handle clients that has entry->data.registered == FALSE.
2455 They are not in the network anymore. Affected file is
2458 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Implemented the sending of the SERVER_SIGNOFF notify in the
2461 server. Affected file is silcd/server.c.
2463 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2464 Added also silc_notify_payload_encode_args into the
2465 lib/silccore/silcnotify.[ch].
2467 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2468 Affected file silcd/packet_receive.c.
2470 * Implemented the SERVER_SIGNOFF notify handling in the client
2471 library. Affected file lib/silcclient/client_notify.c. Also,
2472 implemnted the printing of the SERVER_SIGNOFF info to the
2473 application. Affected file silc/client_ops.c.
2475 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2476 if the deleting was successful. Affected file silcd/idlist.[ch].
2478 * Added support for public key authentication in the connection
2479 authentication protocol in the client library. Affected file
2480 lib/silcclient/protocol.c.
2482 * Changed the server's silc_idlist_get_clients_by_* interface
2483 to support already allocated array so that new entries may be
2484 added to pre-allocated array. Affected file silcd/idlist.[ch].
2485 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2486 and command replies.
2488 * All command reply functions in the server now calls the
2489 pending command callback even if error occured. This way the
2490 error will be delivered to the client as well. Affected files
2491 silcd/command.c and silcd/command_reply.c.
2493 * Fixed INFO command to return local server's info if no server
2494 was provided. Affected file lib/silcclient/command.c.
2496 * Removed RESTART command for good. Updated the code and the
2499 * Rewrote parts of the task system. It is a bit simpler now.
2500 Removed unsued task priorities. The affected files are
2501 lib/silcutil/silctask.[ch].
2503 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Moved the USERS printing from the library to the application.
2506 Affected files lib/silcclient/command.c and silc/client_ops.c.
2508 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2512 * Added channel key re-key support. The re-key is perfomed
2513 only by the router and is done once in an hour. Added `rekey'
2514 field to the SilcChannelEntry in the server. Affected files
2515 silcd/server.c and silcd/idlist.h.
2517 * Added silc_task_unregister_by_context into the file
2518 lib/silcutil/silctask.[ch].
2520 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Added SILC_UMODE_GONE mode to indicate when the client is not
2523 present in the SILC network. Added also support to the local
2524 command AWAY that will set this mode. Added support of showing
2525 "xxx is gone" in WHOIS command. The USERS command shows the
2526 gone status as well.
2528 * Fixed setting server and router operator privileges in the
2529 server's UMODE command. Affected file silcd/command.c.
2531 * Merged the SKE KE1 and KE2 payloads into one payload. The
2532 new KE payload is equivalent to the old KE2 payload.
2534 Cleaned up the SKE Start Payload parsing. It now uses the
2535 simple buffer unformatting to do the parsing. A lot faster
2538 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2539 to the SKE that is used to indicate whether both of the SKE
2540 parties should perform authentication. By default only the
2541 responder performs authentication. By setting this flag also
2542 the initiator must do authentication. By default it is unset
2543 since in normal SKE case, client to server connection, only
2544 the responder should do authentication. When doing SKE between
2545 two clients both should perform authentication. Updated the
2546 code and the protocol specs.
2548 * A little fix to IDENTIFY command in the server. Search the
2549 client first by hash not nickname. Affected file is
2552 * Fixed the silc_client_close_connection to support closing
2553 the client to client connections wihtout deleting too much
2554 data. Affected file lib/silcclient/client.c.
2556 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2557 are received if protocol used to be active but is not anymore
2558 the application would crash due to NULL pointer dereference.
2559 Affected files silcd/server.c and lib/silcclient/client.c.
2561 * Added `hash' field to the SilcClientConnection to include
2562 the hash function negotiated in the SKE protocol.
2564 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2565 to set the channel founder authentication data. A client can
2566 claim the founder rights later by providing the authentication
2567 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2568 This way the channel founder can regain the channel founder
2569 privileges even it is left the channel. This works only on
2570 local server and the client must be connected to the same
2571 server to be able to regain the founder rights. Updated the
2572 protocol specs accordingly.
2574 Added support to the CMODE command in the client to set the
2575 founder auth data. Read the README to see how to set it.
2577 Added support to the CUMODE command to claim the founder
2578 rights. Read the README to see how to do it.
2580 Added support for the founder authentication to the Channel
2581 Entry in the server. Affected file silcd/idlist.h.
2583 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2584 server's CMODE command. Affected file silcd/command.c.
2586 * Added the following new functions into lib/silccore/silcauth.[ch]:
2587 silc_auth_get_method and silc_auth_get_data.
2589 * The server now saves the remote hosts public key to the
2590 SilcIDListData pointer. Affected file silcd/protocol.c.
2592 * The normal server now does not remove the channel entry from
2593 the cache if the founder authentication data is set. It used
2594 to remove it if the founder was the last one on the channel on
2595 the server and left the channel. The auth data is saved and
2596 if the channel is re-joined later the old entry is used with
2597 the old auth data. Affected files silcd/command_reply.c and
2600 * Removed the `pkcs' field from the SilcIDListData structure
2601 in the server; it is not used. Affected file silcd/idlist.h.
2603 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Fixed packet processing on slow links. Partial packets were
2606 never re-processed because the incoming data buffer was cleared
2607 by the application. Application must not directly clear the
2608 sock->inbuf, the packet processing routines handle it. Fixed
2609 this in client library and in server.
2611 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Fixed the WHOIS and IDENTIFY send reply function to really
2614 check whether to send list or just one entry. Affected file
2617 * Cleaned up the LEAVE command's channel key distribution. The
2618 affected file silcd/command.c.
2620 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2621 can enforce the channel mode as well. In that case the ID
2622 includes the ID of the server. The code now enforces the
2623 mode change if the router have different mode than the server.
2625 * The notify client operation with CMODE_CHANGE notify can now
2626 return NULL client_entry pointer if the CMODE was not changed
2627 by client. Application must check for this.
2629 * Added <Server ID> argument to INFO command to support server
2630 info fetching by Server ID.
2632 * Added silc_server_announce_get_channel_users to get assembled
2633 packets of channel users of the specified channel. Affected
2634 file silcd/server.[ch].
2636 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2637 was freed underneath the ID Cache.
2639 * Re-announce clients when the server received CHANNEL_CHANGE
2640 notify from the router. Affected file silcd/packet_send.c.
2642 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2645 crashed since it did not handle the fact that there is no cipher
2646 called "3" and didn't check the error condition. Now fixed.
2648 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2649 flag. It can be used to send message requests.
2651 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Implemented the RESTART command in the client.
2655 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2656 notice type messages. Added notice printing to the user
2659 * The channel keys are not re-generated if the channel's mode
2660 is PRIVKEY, ie private key on the channel exists. Affected
2661 files silcd/server.c and silcd/command.c.
2663 * Fixed a little bug in channel message delivery when channel
2664 private keys are set in the server. Affected file is
2665 silcd/packet_send.c.
2667 * Changed the setting on channel->on_channel = TRUE from the
2668 silc_client_save_channel_key to the JOIN command reply. The
2669 key payload is not received if the private channel key is set.
2670 Affected file lib/silcclient/command_reply.c and the
2671 lib/silcclient/client_channel.c.
2673 * When the CMODE_CHANGE notify is sent and the channel private
2674 key mode is removed the channel key must be re-generated in
2675 other cells as well. Added this support for the router in the
2676 silcd/packet_receive.c.
2678 * Added new local command NOTICE to send notice message on
2679 channel. Affected file silc/local_command.[ch].
2681 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Added new local command ME to the client. It is used to send
2684 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2685 some action. Affected file silc/local_command.[ch].
2687 * Changed channel_message and private_message client operations
2688 to deliver the message flags to the application. Added also
2689 the `flags' arguments to the silc_client_send_channel_message
2690 and silc_client_send_private_message functions. Affected file
2693 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * Redefined the Private Message Payload to support private message
2696 keys and to support the new private message flags. Updated
2697 the protocol specs. Flags makes it possible to have for example
2698 CTCP style messages.
2700 * Added new type SilcPrivateMessagePayload and defined an API
2701 for it in the lib/silcclient/silcprivate.[ch].
2703 * Tested private message private keys successfully. Tested the
2704 private message key set, unset and list commands with the new
2707 * Redefined the Channel Message Payload to include the channel
2708 message flags (equal with private message flags) to support
2709 for example CTCP style messages.
2711 * Defined some of the message (for channel and private message)
2712 flags. Updated the protocol specs and added the flags to the
2713 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2715 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Added SilcKeyAgreementStatus type to the key agreement routines
2718 to indicate the current status and error if one occured.
2719 The status types are defined in the lib/silcclient/silcapi.h.
2721 * Added new local command KEY that is used to set and unset private
2722 keys for channels, set and unset private keys for private messages
2723 with remote clients and to send key agreement requests and
2724 negotiate the key agreement protocol with remote client. The
2725 key agreement is supported only to negotiate private message keys,
2726 it currently cannot be used to negotiate private keys for channels,
2727 as it is not convenient for that purpose.
2729 * Fixed a minor pending callback setting bug in the function
2730 silc_client_get_client_by_id_resolve, now the function works.
2731 Affected file lib/silcclient/idlist.c.
2733 * Added function silc_net_get_local_port to get local bound
2734 port by socket. Added to lib/silcutil/silcnet.[ch].
2736 * Added `sockets' and `sockets_count' fields to the SilcClient
2737 object. They hold the sockets of the listenning sockets in
2738 the client. Listenning sockets may be for example the key
2739 agreement server. Affected file lib/silcclient/client.[ch].
2740 Added functions the silc_client_add_socket and the
2741 silc_client_del_socket. They are exported to the application
2744 * Added ~./silc/clientkeys to support other client's public keys.
2746 * Renamed verify_server_key client operation to verify_public_key
2747 and added one argument to indicate the type of the connection
2748 (server, client etc.).
2750 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Added silc_server_connection_auth_request to handle the
2753 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2754 silcd/packet_receive.[ch].
2756 * Added silc_server_send_connection_auth_request into the
2757 silcd/packet_send.c to send the connection auth request packet.
2759 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2762 * Fixed the public key authentication in responder side in the
2763 server. The `auth_data' pointer includes the SilcPublicKey
2764 not the path to the public key. Affected file silcd/protocol.c.
2766 * Implemented the public key authentication in the initiator side
2767 in the server. Affected file silcd/protocol.c.
2769 * Removed the [RedirectClient] config section from the server
2770 configuration. Is not needed and I don't want to implement it.
2772 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Cleaned up the CMODE command in the server. It now works
2775 correctly and supports all the modes defined in the protocol.
2776 Affected file is silcd/command.c.
2778 * Added `hmac_name' field to the SilcChannelEntry in the server
2779 to hold the default HMAC of the channel. It can be set when
2780 creating the channel (with JOIN command). Affected files
2783 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2784 type to indicate the change of the current cipher and hmac
2785 on the channel. Client can safely ignore the <cipher> argument
2786 (if it chooses to do so) since the CHANNEL_KEY packet will
2787 force the channel key change anyway. The <hmac> argument is
2788 important since the client is responsible of setting the new
2789 HMAC and the hmac key into use.
2791 * Fixed the CMODE command in the client library as well.
2793 * Tested CMODE command in router environment successfully.
2795 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2797 * Show the version of the remote client (or server) when connecting
2798 to the server. It is logged to the log file. Affected file
2799 is silcd/protocol.c.
2801 * Fixed the KILLED notify handling in the client library. The
2802 client must be removed from all channels when receiving the
2805 Also, do not remove the client entry when giving the KILL
2806 command but when the KILLED notify is received.
2808 * Removed silc_idlist_find_client_by_nickname from the server.
2809 Not needed anymore. Affected files silcd/idlist.[ch].
2811 * Implemented the CHANNEL_CHANGE notify type handling to the
2812 server. Affected file silcd/server.c.
2816 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Added silc_server_send_notify_invite to send the INVITE
2819 notify between routers.
2821 * Implemented the INVITE command correctly to the server.
2823 * Implemented the INVITE notify type handling in the server.
2825 * Implemented the INVITE command to the client library and on the
2828 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Added function silc_server_get_client_resolve to find the
2831 client entry by ID from all ID lists and then resolve it
2832 (using WHOIS) if it cannot be found. Affected file is
2835 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Implemented the BAN command to the client library.
2839 * The JOIN command in the server now checks the invite list
2842 * Changed the silc_command_reply_payload_encode_va and the
2843 silc_command_payload_encode_va to support that if argument is
2844 NULL it ignores and checks the next argument. Affected file
2845 lib/silccore/silccommand.c.
2847 * Added silc_server_send_notify_ban to send the BAN notify
2848 type between routers.
2850 * Chaned the silc_notify_payload_encode to support that if
2851 argument is NULL it ignores and checks the next argument.
2852 Affected file lib/silccore/silcnotify.c.
2854 * Tested ban lists in router environment successfully.
2856 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Implemented BAN command to the server, in silcd/command.[ch].
2860 * Removed the BAN and INVITE_LIST modes from the CMODE command
2863 * Added function silc_string_match to regex match two strings.
2864 Affected files lib/silcutil/silcutil.[ch].
2866 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Redefined parts of the SilcChannelEntry in the server to support
2869 the new ban and invite lists.
2871 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Redefined the INVITE command. The same command can be used to
2874 invite individuals to the channel but also to manage the invite
2875 list of the channel (to add to and remove from the invite list).
2876 Updated the protocol specs.
2878 * Added new command SILC_COMMAND_BAN that can be used to manage
2879 the ban list of the channel. Updated the protocol specs.
2881 * Removed the channel modes: the SILC_CMODE_BAN and the
2882 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2883 in the CMODE command. The equivalent features are now available
2884 using INVITE and BAN commands. Updated the protocol specs.
2886 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2887 in the network about change in the current ban list. The notify
2888 type is not used by the client.
2890 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2891 support the invite lists.
2893 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Added new function silc_string_regexify that converts string
2896 including wildcard characters into regex string that can
2897 be used by the GNU regex library. Added into the file
2898 lib/silcutil/silcutil.[ch].
2900 Added silc_string_regex_combine to combine to regex strings
2901 into one so that they can be used as one regex string by
2902 the GNU regex library. Added into the file
2903 lib/silcutil/silcutil.[ch].
2905 Added silc_string_regex_match to match two strings. It returns
2906 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2908 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Imported GNU regex to the soruce tree into lib/contrib.
2911 Fixed some compiler warning from the regex.c.
2913 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Fixed MOTD command in the server to work in router environment.
2917 * Fixed the MOTD command in the client library to support
2918 the server argument in the command.
2920 * Added `nickname_len' argument to the silc_idlist_add_client
2921 in the server, as the `nickname' argument may be binary data
2924 * Added silc_idlist_get_channels to return all channels from
2927 * Implemented LIST command to the server. Affected file is
2930 * Implemented the LIST command to the client library and on the
2933 * Added [<user count>] argument to the LIST command reply.
2934 With private channels the user count is not shown.
2936 * Updated TODO and README.
2938 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * The client entry's data.registered must be TRUE even with
2941 global client entry on global client list. The data.registered
2942 is used to check whether the client is anymore in the network,
2943 for example with WHOWAS command so it must be valid.
2945 * Fixed the WHOWAS command in the server. It now actually works
2946 in router environment. Added function into silcd/command_reply.c
2947 silc_server_command_reply_whowas_save.
2949 * Added silc_idlist_purge function to the silcd/idlist.c
2950 to periodically purge the ID Cache.
2952 * Fixed INFO command in the server. It works now in router
2953 environment. Added <server name> argument to the INFO command
2954 reply. Updated the protocol specs.
2956 * Fixed minor bug in silc_idcache_purge to not purge if the
2957 expire value is zero.
2959 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2960 they were buggy because of the WHOWAS information.
2962 * Fixed local command MSG to handle the async resolving of
2963 the remote client properly. It used to fail the first MSG.
2964 Affected file silc/local_command.c.
2966 * Added `data_len' field to SilcIDCache context.
2968 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Update TODO. Todo in commands in the server.
2972 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2975 used by routers as broadcast packet to inform other routers
2976 about the changed user mode.
2978 Implemented the notify handling in the server. Affected file is
2979 silcd/packet_receive.c. Added the function
2980 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2982 * Added new generic Channel Payload and deprecated the New Channel
2983 Payload. The New Channel Payload is now the generic Channel
2986 * Added new argument `mode' to the silc_server_send_new_channel
2987 as it is required in the Channel Payload now.
2989 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2990 and created a new and real SilChannelPayload to represent the
2991 new generic Channel Payload. Implemented the encode/decode
2992 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2994 * Added silc_server_get_client_channel_list to return the list
2995 of channels the client has joined for WHOIS command reply.
2996 Affected file silcd/server.[ch].
2998 * Implemented the channel list sending in the WHOIS command reply
2999 in server and in the client.
3001 Implemented the channel list displaying on the user interface
3002 as well. Affected file silc/client_ops.c.
3004 * Added silc_channel_payload_parse_list to parse list of Channel
3005 Payloads. It returns SilcDList list of SilcChannelPayloads.
3006 Client for example can use this function to parse the list of
3007 channels it receives in the WHOIS command reply. The caller
3008 must free the list by calling silc_channel_payload_list_free.
3009 Affected files lib/silccore/silcchannel.[ch].
3011 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Added one new argument <user mode> to the WHOIS command reply
3014 to return the mode of the user in SILC. Updated the protocol
3017 Implemented it to the server and client.
3019 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Fixed the mode printing on the user interface on joining.
3022 Affected file silc/client_ops.c.
3024 * Implemented the UMODE command and user modes in general to the
3025 client library and to the user interface.
3027 * Implemented the UMODE command to the server.
3029 * The server now sends UNKNOWN_COMMAND error status if client sends
3030 unknown command. Affected file silcd/command.c.
3032 * All server commands now handle the command identifier the right
3033 way when sending the command reply to the client. The client can
3034 use to identify the command replies with the identifier.
3036 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Added silc_server_get_client_route to resolve the route to
3039 the client indicated by the client ID. Affected file is
3042 * Added silc_server_relay_packet as general function to relay
3043 packet to arbitrary destination. This deprecates functions
3044 like _send_private_message_key, _relay_notify etc. Affected
3045 file is silcd/packet_send.[ch].
3047 Removed silc_server_send_key_agreement,
3048 silc_server_send_private_message_key and
3049 silc_server_packet_relay_notify functions from the file
3050 silcd/packet_send.[ch].
3054 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3055 server. Affected file silcd/packet_receive.[ch].
3057 * Implemented the KILL command to the client. Implemented the
3058 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3059 Affected files lib/silcclient/command[_reply].c and
3060 lib/silcclient/client_notify.c. Implemented the KILL notify
3061 printing in the user inteface.
3063 * Fixed a lot silc_parse_nick memory leaks from the client
3064 library in the file lib/silcclient/command.c.
3066 * Changed the silc_server_send_notify_on_channels's `sender'
3067 argument from SilcSocketConnection to SilcClientEntry to
3068 check the sender as entry and not as connection object and not
3069 to send to the client provided as argument. The affected file
3070 is silcd/packet_send.[ch].
3072 * The notify packets that are destined directly to the client used
3073 to not to be processed by the server. Now changed that and the
3074 server processes all notify packets. After relaying the packet
3075 to the client the notify packet is processed in the server.
3077 * The silc_server_free_client_data now checks whether there is
3078 pending outgoing traffic for the client and purges the data to
3079 the network before removing the client entry.
3081 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3084 an client is killed from the SILC Network. Updated the protocol
3087 Added new function silc_server_send_notify_killed to the
3088 silcd/packet_send.[ch].
3090 * Added function silc_server_packet_relay_notify to relay notify
3091 packets that are destined directly to a client. In this case
3092 the server does not process the notify packets but merely relays
3093 it to the client. Affected file silcd/packet_send.[ch].
3095 Added also silc_server_packet_process_relay_notify to check
3096 whereto relay the notify. Affected file is
3097 silcd/packet_receive.[ch].
3099 * Implemented the KILL command to the server.
3103 * Added the backup schema desgined last fall to the protocol
3104 specs for everyone to see. The specification is in the
3105 *-spec-xx.txt draft and the packet type definitions for the
3106 backup routers is in *-pp-xx.txt draft. Thusly, added also
3107 new packet type SILC_PACKET_CELL_ROUTERS.
3109 * A big security problem in the implementation discovered. The
3110 signoff of an client did not cause new channel key generation
3111 which it of course should've done. The channel keys must be
3112 always re-generated when client leaves (or signoffs) the channel.
3113 The silc_server_remove_from_channels funtion now handles
3114 the channel key re-generation.
3116 * Added `sender' argument to the silc_server_send_notify_on_channels
3117 to not to send the client provided as argument. Affected file
3118 silcd/packet_send.[ch].
3120 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Implemented OPER and SILCOPER commands into the server and
3125 * Added silc_auth_verify and silc_auth_verify_data to verify
3126 the authentication directly from the authentication payload.
3127 It supports verifying both passphrase and public key based
3128 authentication. Affected file lib/silccore/silcauth.[ch].
3130 * Added `hash' field to the SilcIDListData structure. It is the
3131 hash negotiated in the SKE protocol. Affected file is
3134 * Slight redesigning of the SilcAuthPayload handling routines.
3135 Do not send SilcPKCS but SilcPublicKey as argument.
3137 * Implemented the public key authentication support to the
3138 serverconfig. The public key is loaded from the provided path
3139 and saved as authentication data to void * pointer. Thus,
3140 changed the unsigned char *auth_data to void *auth_data;
3142 * Fixed SHUTDOWN command to send the reply before the server
3143 is shutdown. :) Affected file silcd/command.c.
3145 * Fixed fatal bug in CONNECT command. The hostname was invalid
3146 memory and server crashed. Affected file silcd/command.c.
3148 * Fixed fatal bug in CLOSE command. The server_entry became
3149 invalid but was referenced later in the command. Affected file
3152 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Fixed fatal bug in failure packet handling. Server ignored
3155 the failure and thus crashed when it came.
3159 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3162 that the command may be executed only once in (about) 2 seconds.
3163 The old SILC_CF_LAG flag is same but allows command bursts up
3164 to five before limiting.
3166 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3167 server code. Various commands now includes the CF_LAG_STRICT
3168 flag to disallow any kind of miss-use of the command.
3170 * Fixed the silc_buffer_unformat to not to allocate any data
3171 if the length of the data is zero. It used to allocate the
3172 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3174 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Changed the format of AdminConnection configuration section
3177 in the server. Added username of the admin to the format.
3178 Affected files silcd/serverconfig.[ch].
3180 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3181 to return admin configuration data by host, username and/or
3184 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Implemented WHOWAS command to the server. Added the functions:
3188 silc_server_command_whowas_parse,
3189 silc_server_command_whowas_send_reply,
3190 silc_server_command_whowas_from_client and
3191 silc_server_command_whowas_from_server
3193 * Added <Client ID> argument to the WHOWAS command reply. Updated
3194 the protocol specs accordingly.
3196 * Implemented WHOWAS command and command_reply to the client
3199 Implemented the WHOWAS printing on the user interface.
3201 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Added new argument to the WHOWAS command reply, the real name.
3204 It is an optional argument. Updated the protocol specs.
3206 * Added SilcIDCacheDestructor callback that is registered when
3207 the SilcIDCache is allocated. The callback is called when
3208 an cache entry in the ID Cache expires, or is purged from the
3209 cache. Added into lib/silccore/idcache.[ch].
3211 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3212 to destruct the client entries when the cache entry expires.
3213 Other ID Cache's in server and in the client library ignores
3216 * If the ID Cache entry's `expire' field is zero then the entry
3217 never expires. Added boolean `expire' argument to the
3218 silc_idcache_add function in the lib/silccore/idcache.[ch].
3219 If it is TRUE the default expiry value is used.
3221 * Added silc_server_free_client_data_timeout that is registered
3222 when client disconnects. By default for 5 minutes we preserve
3223 the client entry for history - for WHOWAS command.
3225 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added support to the server to enforce that commands are not
3228 executed more than once in 2 seconds. If server receives
3229 commands from client more frequently, timeout is registered
3230 to process the commands. Affected file silcd/command.c.
3231 Added new function silc_server_command_process_timeout.
3233 * Changed NICK_NOTIFY handling in client library to check that
3234 if the client's nickname was changed, so there is no need to
3235 resolve anything from the server.
3237 * Removed error printing from the WHOIS and IDENTIFY commands.
3238 If error occurs then it is ignored silently in the client library.
3239 The application, however, may map the received error to
3240 human readable error string. The application currently maps
3241 the NO_SUCH_NICKNAME error to string.
3243 * Made the command status message public to the application. Moved
3244 them from lib/silcclient/command_reply.c to
3245 lib/silcclient/command_reply.h. The application can map the
3246 received command status to the string with the
3247 silc_client_command_status_message function.
3249 * Added check to the server to check that client's ID is same
3250 as the Source ID in the packet the client sent. They must
3253 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Added dist-bzip hook to the Makefile.am to make bzip2
3256 compressed distributions.
3258 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Server now enforces the maximum length for the nickname and
3261 the channel as protocol specification dictates. 128 bytes for
3262 nickname and 256 bytes for channel name.
3264 * Moved the WHOIS printing to the application. The client libary
3265 does not print out the WHOIS information anymore, the application
3266 must do it. Renamed silc_client_command_reply_whois_print to
3267 the silc_client_command_reply_whois_save.
3269 The client's idle time is also sent to the application now, and
3270 the idle is shown on screen.
3272 * Added silc_client_command_reply_identify_save to save the
3273 received IDENTIFY entries.
3275 * Do not check for channel private keys in message sending and
3276 reception if the channel does not have the PRIVKEY mode set.
3277 Affected file lib/silclient/client_channel.c.
3279 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3282 just surfaced after chaning the JOIN procedure.
3284 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Added silc_client_get_clients_by_list to get client entries
3287 from Client ID list, that is returned for example by JOIN
3288 and USERS command replies. The application should use this
3289 function for example when JOIN command reply is received to
3290 resolve the clients already on the channel (library does not
3291 do that anymore as USERS command reply is not used in the JOIN
3292 procedure anymore). Affected files lib/silcclient/silcapi.h and
3293 lib/silcclient/idlist.c.
3295 * JOIN command reply and USERS command reply returns now SilcBuffer
3296 pointers instead of unsigned char pointers when returning
3297 the client list and mode list.
3299 * Added <Client ID> argument to the JOIN command reply, mainly
3300 for the server to identify for which client the command was
3301 originally sent. Updated protocol specs accordingly.
3303 * Added SilcDlist private_key pointer to the SilcChannelEntry
3304 in the client to support the channel private keys. Affected
3305 file is lib/silcclient/idlist.h.
3307 * Added SilcChannelPrivateKey argument to the function
3308 silc_client_send_channel_message so that application can choose
3309 to use specific private ke if it wants to. If it is not provided,
3310 the normal channel key is used, unless private keys are set.
3311 In this case the first (key that was added first) is used
3312 as the encryption key.
3314 * Implemented the support for channel private key handling.
3315 Implemented the following functions:
3317 silc_client_add_channel_private_key,
3318 silc_client_del_channel_private_keys,
3319 silc_client_del_channel_private_key,
3320 silc_client_list_channel_private_keys and
3321 silc_client_free_channel_private_keys
3323 Affected file lib/silcclient/client_channel.c.
3325 * Added the support for the private keys in the channel message
3326 sending and encryption and in the message reception and
3327 decryption. Affected funtions are
3328 silc_client_send_channel_message and silc_client_channel_message.
3330 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Added SKE's key verify callback to the client library's
3333 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3335 * Removed the statement that server (or router) must send USERS
3336 command reply when joining to the channel so that the client
3337 knows who are on the channel. Instead, the client list and
3338 client's mode list is now sent in the JOIN command reply to the
3339 client who joined channel. This is better solution.
3341 * Added function silc_server_get_users_on_channel and function
3342 silc_server_save_users_on_channel to the silcd/server.[ch].
3344 * Removed function silc_server_command_send_users from the
3347 * Do not show topic on the client library anymore. The topic is
3348 sent in the command reply notify to the application and the
3349 application must show the topic now.
3351 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Added client searching by nickname hash into the IDENTIFY and
3354 WHOIS commands in the server as they were clearly missing from
3355 them. Affected file is silcd/command.c.
3357 * Fixed a bug in private message receiving in the client library.
3358 The remote ID was freed and it wasn't supposed, now it is
3361 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Minor fix to the channel payload; allocate the data area, as it
3364 needs to be of specific length.
3366 * If the key agreement port is zero then the operating
3367 system will define the bound port. Affected files are
3368 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3370 * Added new function silc_channel_payload_decrypt into the file
3371 lib/silccore/silcchannel.[ch].
3373 * Moved the channel message etc, check from silc_packet_decrypt
3374 to applications. The library calls now a generic
3375 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3376 when the packet is either normal or special. This was done to
3377 allow more wide range of checking that was not allowed when
3378 the code was in library. Now applications can do virtually any
3379 checks to the packet and return to the library the decision how
3380 the packet should be processed. Affected files are
3381 lib/silccore/silcpacket.[ch].
3383 Added silc_server_packet_decrypt_check to the server and
3384 silc_client_packet_decrypt_check to the client library.
3386 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3387 to send with specified source and destination information.
3389 * Channel message delivery between routers was broken after the
3390 channel key distribution was fixed earlier. The channel key
3391 was used be to distributed to other routers as well which is not
3392 allowed by the protocol. Now this is fixed and channel keys
3393 really are cell specific and the channel message delivery between
3394 routers comply with the protocol specification.
3396 * Fixed various commands in server to check also the global list
3397 for the channel entry and not just the local list. The affected
3398 file silcd/command.c.
3400 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Added assert()s to buffer formatting and unformatting routines
3403 to assert (if --enable-debug) when error occurs. Affected
3404 file: lib/silcutil/silcbuffmt.c.
3406 * Changed to auto-reconnect to check whether the remote host is
3407 router and register the re-connect timeout if it is. It used
3408 to check that whether we are normal server, but router must do
3409 auto-reconnect with another router as well. Affected file
3412 * Removed the [<key len>] option from CMODE command as the cipher
3413 name decides the key length, nowadays. See the defined ciphers
3414 from the protocol specification.
3416 * Added [<hmac>] option to the CMODE command to define the HMAC
3417 for the channel. Added SILC_CMODE_HMAC channel mode.
3419 * Added [<hmac>] option for the JOIN command so that user can
3420 select which HMAC is used to compute the MACs of the channel
3423 * Added Hmac field to the Channel Message Payload. The integrity
3424 of plaintext channel messages are now protected by computing
3425 MAC of the message and attaching the MAC to the payload. The
3426 MAC is encrypted. Now, it is clear that this causes some
3427 overhead to the size of the packet but rationale for this is that
3428 now the receiver can verify whether the channel message decrypted
3429 correctly and also when private keys are set for the channel the
3430 receiver can decrypt the packet with several keys and check from
3431 the MAC which key decrypted the message correctly.
3433 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3434 lib/silccrypt/silccipher.[ch].
3436 * Added silc_hash_len to return the digest length into the
3437 lib/silcrypt/silchash.[ch].
3439 * Rewrote parts of Silc Channel Payload interface in the
3440 lib/silccore/silcchannel.[ch]. The encode function now also
3441 encrypts the packet and parse function decrypts it.
3443 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Fixed a minor formatting bug in the SKE's key material processing.
3446 It actually might have processed the keys wrong way resulting
3449 * Redefined the mandatory HMAC algorithms and added new algorithms.
3450 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3451 and hmac-md5 truncated to 96 bits. The mandatory is now
3452 hmac-sha1-96. Rest are optional (including the one that used
3453 to be mandatory). Rationale for this is that the truncated HMAC
3454 length is sufficient from security point of view and can actually
3455 make the attack against the HMAC harder. Also, the truncated
3456 HMAC causes less overhead to the packets. See the RFC2104 for
3459 * Added new [hmac] configuration section. The SKE used to use
3460 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3461 is of course wrong. The official names that must be proposed in
3462 the SKE are the ones defined in the protocol specification
3463 (hmac-sha1-96 for example). The user can configure any hmac
3464 using any hash function configured in the [hash] section. At
3465 least, the mandatory must be configured.
3467 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3469 * Added HMAC list to the SKE proposal list. It has now both
3470 hash algorithm list and HMAC list. This makes the protocol
3471 incompatible with previous versions. The SKE now seems to work
3472 the way it is supposed to work, for the first time actually.
3474 * Defined plain Hash algorithms to the protocol specification.
3477 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Implemented support for key agreement packets into the server.
3480 Added functions silc_server_key_agreement and
3481 silc_server_send_key_agreement. Other than these functions,
3482 server has nothing to do with this packet.
3484 * Added support for private message key packets into the server.
3485 Added functions silc_server_private_message_key and
3486 silc_server_send_private_message_key.
3490 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3491 called in the protocol's final callback instead in the END
3492 protocol state. This makes a little more sense and in the same
3493 time in client we can use the same protocol routines for normal
3494 key exchange and to key agreement packet handling as well.
3496 * Added to both client's and server's KE protocol context the
3497 SilcSKEKeyMaterial pointer to save the key material. We will
3498 bring the key material to the protocol's final callback by doing
3499 this. The final callback must free the key material.
3501 * Added SKE's packet_send callback into client's KE protocol
3502 context so that the caller can choose what packet sending function
3503 is used. This way we can use different packet sending when
3504 doing normal SKE when doing key agreement packet handling (in
3505 the key agreement packet handling we do not want to encrypt
3508 * Implemented the responder side of the key agreement routines
3509 in the client. The client can now bind to specified port and
3510 accept incoming key negotiation. The key material is passed
3511 to the application after the protocol is over.
3513 * Implemented the processing of incoming Key Agreement packet
3514 in the client. Added function silc_client_key_agreement to
3517 * Implemented the intiator side of the key agreement routines
3518 in the client. The client can now initiate key agreement with
3519 another remote client. The key material is passed to the
3520 application after the protocol is over.
3522 * Created client_keyagr.c to include all the key agreement
3525 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3526 SILC_TASK_CALLBACK except that it is not static.
3528 * Created client_notify.c and moved the Notify packet handling
3529 from the client.[ch] into that file.
3531 * Created client_prvmsg.c and moved all private message and
3532 private message key routines from the client.[ch] into that file.
3534 * Create client_channel.c and moved all channel message and
3535 channel private key routines from the client.[ch] into that file.
3537 * Changed silc_client_get_client_by_id_resolve to resolve with
3538 WHOIS command instead of IDENTIFY command, in the file
3539 lib/silclient/idlist.c.
3541 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Implemented the SKE's responder side to the Client library.
3545 * When FAILURE is received to the protocol do not trust it
3546 blindly. Register a timeout to wait whether the remote closes
3547 the connection as it should do it, only after that process the
3548 actual failure. This was changed to both client and server.
3550 * Added client_internal.h to include some of the structures
3551 there instead of client.h in lib/silcclient/.
3553 * Added function silc_task_unregister_by_callback to unregister
3554 timeouts by the callback function.
3556 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Some "Incomplete WHOIS info" errors has been appearing on the
3559 log files. Took away the entry->userinfo check from WHOIS
3560 reply sending. The entry->userinfo is now " " if client did not
3561 provide one. I thought this was fixed earlier but something
3562 is wrong still. Let's see if the error still appears.
3564 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Fixed a minor bug in the login when the channel key is
3567 re-generated in the server. It used to generate the key in
3568 wrong order and thus caused problems in the channel traffic.
3570 * Fixed a minor bug in channel key distsribution after
3571 KICK command. The key was not sent to the router even though
3574 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Added silc_ske_process_key_material_data as generic routine
3577 to process any key material as the SILC protocol dictates. The
3578 function is used by the actual SKE library but can be used by
3579 applications as well. This relates to the private message keys
3580 and the channel private keys since they must be processed the
3581 same way the normal SILC session keys. The protocol dictates
3582 this. Affected files: lib/silcske/silcske.[ch].
3584 Added also silc_ske_free_key_material to free the
3585 SilcSKEKeyMaterial structure.
3587 * Defined silc_cipher_set_key function to set the key for
3588 cipher without using the object's method function. The affected
3589 files: lib/silccrypt/silccipher.[ch].
3591 * Implemented silc silc_client_add_private_message_key,
3592 silc_client_add_private_message_key_ske,
3593 silc_client_del_private_message_key,
3594 silc_client_list_private_message_keys and
3595 silc_client_free_private_message_keys functions in the
3598 Added functions silc_client_send_private_message_key to send
3599 the Private Message Key payload and silc_client_private_message_key
3600 to handle incoming Private Message Key payload.
3602 * Added Cipher field to the Private Message Key payload to set
3603 the cipher to be used. If ignored, the default cipher defined
3604 in the SILC protocol (aes-256-cbc) is used.
3606 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Removed lib/silcclient/ops.h file.
3610 Redefined parts of the SILC Client Library API. Created new
3611 file silcapi.h that deprecates the ops.h file and defines the
3612 published Client Library API. Defined also private message key
3613 API and channel private key API into the file.
3615 This is the file that the application must include from the
3616 SILC Client Library. Other files need not be included by
3617 the application anymore.
3619 * Added new key_agreement client operation callback and also
3620 defined the Key Agreement library API for the application.
3622 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3625 is used by clients to request key negotiation between another
3626 client in the SILC network. If the negotiation is started it
3627 is performed using the SKE protocol. The result of the
3628 negotiation, the secret key material, can be used for example
3629 as private message key.
3631 Implemented the Key Agreement payload into the files
3632 lib/silccore/silauth.[ch].
3634 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Redefined ciphers for the SILC protocol. Added some new ciphers
3637 and defined the key lengths for the algorithms. Changed the
3638 code accordingly. The default key length is now 256 bits.
3640 * Fixed SKE key distribution function silc_ske_process_key_material
3641 when the key length is more than 128 bits. The default key
3642 length in SILC is now 256 bits.
3644 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3645 to indicate unsupported algorithm.
3647 * Renamed rijndael.c to aes.c and all functions as well.
3649 * Fixed a long standing channel key setting bug in client library.
3650 Weird that it has never surfaced before.
3652 * Fixed bug in channel deletion. If the entire channel is removed
3653 then it must also delete the references of the channel entry
3654 from the client's channel list as the client's channel entry and
3655 the channel's client entry share same memory.
3657 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Implemented CONNECT and SHUTDOWN commands in the client.
3661 * Implemented CLOSE command to the client.
3663 * Added the function silc_idlist_find_server_by_name into the
3664 files silcd/idlist.[ch].
3666 Added the function silc_idlist_find_server_by_conn into the
3667 files silcd/idlist.[ch].
3669 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * DIE command was renamed to SHUTDOWN. Updated the both code
3674 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3675 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3677 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3680 * Added function silc_server_create_connection function to create
3681 connection to remote router. My server implementation actually
3682 does not allow router to connect to normal server (it expects
3683 that normal server always initiates the connection to the router)
3684 so the CONNECT command is only good for connecting to another
3687 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3690 or some other client was kicked from the channel.
3692 Implemented the handling of the notify type to both client
3695 Implemented silc_server_send_notify_kicked to send the KICKED
3696 notify. It is used to send it to the server's primary router.
3698 * Implemented the KICK command into server and client.
3700 * Added `query' argument to the silc_idlist_get_client function
3701 to indicate whether to query the client from server or not if
3704 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3705 to indicate that the client is not channel founder.
3709 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Removed the rng context from SilcPacketContext structure and
3712 changed that the packet routine uses the Global RNG API.
3714 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Added support for quit message that client can "leave" on the
3717 channel when it quits the SILC. It is ditributed inside the
3718 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3720 Added silc_server_free_client_data that will take the
3721 signoff message as argument.
3723 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3725 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Updated parts of the protocol specification to keep it up
3730 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3733 payloads in one packet.
3735 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3736 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3737 use now the new List flag.
3739 * Also deprecated the following packet types: REPLACE_ID,
3740 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3742 * Added list support for Notify packet in server.
3744 * Added silc_server_send_notify_channel_change to send the
3745 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3746 the silc_server_send_replace_id.
3748 * Added silc_server_send_notify_nick_change to send the
3749 NICK_CHANGE notify type. Deprecates the function
3750 silc_server_send_replace_id.
3752 * Added silc_server_send_notify_join to send the JOIN notify type.
3753 Deprecates the function silc_server_send_new_channel_user.
3755 * Added silc_server_send_notify_leave to send LEAVE notify type.
3756 Deprecates the function silc_server_send_remove_channel_user.
3758 * Added silc_server_send_notify_cmode and
3759 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3760 types. Deprecates the silc_server_send_set_mode function.
3762 * Added SERVER_SIGNOFF notify type to indicate that server has
3763 quit. This means that all clients on the channel from that
3764 server will drop. This can be also used when netsplit happens.
3766 Deprecated REMOVE_ID packet type since it is not needed anymore
3769 Added silc_server_send_notify_server_signoff to send the
3770 SERVER_SIGNOFF notify type. Deprecates the function
3771 silc_server_send_remove_id.
3773 Added also silc_server_send_notify_signoff to send the
3774 SIGNOFF notify type.
3776 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3777 SILC protocol from this day on. Changed the protocol
3778 specification as well.
3780 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3781 notify type. It is used between routers to notify about
3782 topic changes on a channel.
3784 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3787 * Partly updated the protocol specification to comply with the
3788 changes now made. It is still though a bit outdated.
3790 * The JOIN notify type now takes one extra argument <Channel ID>.
3791 The packet used to be destined to the channel but now the
3792 JOIN type may be sent as list thus it is impossible to
3793 destine it to any specific channel. By adding this argument
3794 it is again possible.
3796 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Added CREDITS file. The CHANGES and CREDITS file will appear
3799 in the distribution as well.
3801 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3804 types in the server's silcd/packet_receive.c.
3806 * Implemented CMODE and CUMODE to work in router environment.
3808 * Fixed minor encoding and decoding buglet from the
3809 lib/silccore/silcmode.c.
3811 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3814 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3816 * Changed all SilcConfigServer* and silc_config_server* to
3817 SilcServerConfig* and silc_server_config*, respectively.
3820 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Associated the ID (client or server ID) to the Authentication
3823 Payload to avoid any possibility of forging. Updated the
3824 protocol specification and the code accordingly.
3826 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * The RSA key length is now save to the RsaKey context in the
3829 key generation process in lib/silccrypt/rsa.c. The key length
3830 is now used to figure out the maximum size of the block allowed
3831 to be encrypted/signed.
3833 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3834 is equivalent to the silc_mp_mp2bin but does not allocate any
3837 * Changed silc_mp_mp2bin API to take length argument. If it is
3838 non-zero then the buffer is allocated that large. If zero, then
3839 the size is approximated using silc_mp_sizeinbase, which however
3842 * Created Global RNG API which is global RNG that application can
3843 initialize. After initializing, any routine anywhere in the
3844 code (including library) can use RNG without allocating a new
3845 RNG object. This was done to allow this sort of use of the
3846 RNG in code that has no chance to allocate RNG object. All
3847 applications currently allocate this and many routines in the
3848 library use this. Affected file lib/silccrypt/silcrng.[ch].
3850 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3851 it to use the Global RNG API.
3853 * Defined Authentication Payload into protocol specification that
3854 is used during SILC session to authenticate entities. It is
3855 used for example by client to authenticate itself to the server
3856 to obtain server operator privileges.
3858 Implemented this payload into the lib/silccore/silcauth.[ch].
3859 Implemented also routines for public key based authentication
3860 as the new protocol specification dictates.
3862 Moved definitions of different authentication methods from
3863 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3865 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3866 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3867 silc_pkcs_verify_with_hash functions into the file
3868 lib/silccrypt/silcpkcs.[ch].
3870 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * The client entry's userinfo pointer must be always valid.
3873 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3874 will fail since it requires the userinfo. Now, the userinfo
3875 is allocated as "" if actual userinfo does not exist. Actually,
3876 it must exist and it is totally Ok to drop client connections
3877 that does not announce the userinfo. However, we will make
3878 this workaround for now.
3880 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3881 to return the remote port by socket.
3883 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3886 SILC_SERVER_PENDING_EXEC and added an new macro
3887 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3888 data or when error occurs while processing the pending command.
3890 Added new argument `destructor' into silc_server_command_pending
3891 and to the SilcServerCommandPending object. This destructor is
3892 now called after calling the pending callback or if error occurs
3893 immediately. If error occurs the actual pending callback won't
3894 be called at all - only the destructor. The destructor may be
3895 NULL if destructor is not needed.
3897 All this applies for client library code as well. Similar
3898 changes were made there as well for the pending commands.
3900 In the client, the application must now allocate the
3901 SilcClientCommandContext with the silc_client_command_alloc
3904 * Added reference counter to the SilcServerCommandContext. Added
3905 function silc_server_command_alloc and silc_server_command_dup
3908 Same type of functions added to the client library for the same
3911 * Removed the cmd_ident from IDListData away since it is now
3912 global for all connections. It is the command identifier used
3913 in command sending and with pending commands. The affected file
3916 * Added reference counter to the SilcSocketConnection objecet to
3917 indicate the usage count of the object. The object won't be
3918 freed untill the reference counter hits zero. Currently only
3919 server uses this, and client ignores it. The client must be
3920 set to use this too later. The affected files are
3921 lib/silccore/silcsockconn.[ch]. Added also the function
3922 silc_socket_dup to increase the reference counter.
3924 This was mainly added because it is possible that the socket
3925 is removed underneath of pending command or other async
3926 operation. Now it won't be free'd and proper DISCONNECTING
3927 flags, etc. can be set to avoid sending data to connection that
3928 is not valid anymore.
3930 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3931 the connection. After that it sets SILC_SET_DISCONNECTED.
3932 It is, however, possible that the socket data is not still freed.
3933 The silc_server_packet_process now checks that data is not
3934 read or written to connection that is DISCONNECTED. The socket
3935 get's freed when the reference counter hits zero.
3937 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Changed the client operation API: channel_message operation's
3940 `sender' is now the client entry of the sender, not the nickname
3941 and the `channel' is the channel entry, not the channel name.
3943 In the private_message operation the `sender' is now also the
3944 client entry of the sender not the nickname.
3946 Affected file is lib/silcclient/ops.h and all applications
3947 using the client operations.
3949 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Moved the calling of ops->connect() from connect_to_server_final
3952 into receive_new_id functin since that is the point when the
3953 client is actually allowed to send traffic to network. The
3954 affected file is lib/silcclient/client.c.
3956 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3959 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3960 (if needs broadcasting) instead of broadcasting the packets one
3961 by one which would make a burst in the network traffic.
3963 * Added `broadcast' argument to the functions in silcd/server.[ch]
3964 silc_server_create_new_channel[_with_id] to indicate whether
3965 to send New Channel packet to primary router.
3967 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Added new function into the silcd/server.[ch] files:
3970 silc_server_create_new_channel_with_id to create new channel with
3971 already existing Channel ID.
3973 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3974 lib/silccore/silcpacket.h. This packet is used t send list of
3975 Set Mode payloads inside one packet. Server uses this to set
3976 the modes for the channels and clients on those channels, that it
3977 announced to the router when it connected to it. The protocol
3978 specification has been updated accordingly.
3980 * The silc_server_new_channel did not handle the packet coming
3981 from normal server as it normally does not send that. However,
3982 when it announces its channels it does send it. Implemented
3983 the support for that.
3985 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3986 into the file lib/silccore/id.h.
3988 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Fixed memory leaks in the functions silc_idlist_del_client,
3991 silc_idlist_del_channel and silc_idlist_del_server in the file
3992 silcd/idlist.c. All of those leaked like a sieve.
3994 * Fixed some small memory leaks in the client's function
3995 silc_client_notify_by_server.
3997 * Added functions into silcd/server.c: silc_server_announce_clients,
3998 silc_server_announce_channels and silc_server_announce_server.
3999 These functions are used by normal and router server to announce
4000 to its primary router about clients, channels and servers (when
4001 router) that we own. This is done after we've connected to the
4004 These functions effectively implements the following packet types:
4005 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4006 and SILC_PACKET_NEW_ID_LIST.
4008 * Added new functions into the silcd/packet_receive.[ch]:
4009 silc_server_new_id_list, silc_server_new_channel_list and
4010 silc_server_new_channel_user_list to handle the incoming
4011 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4013 * Added support of changing Channel ID in the function
4014 silc_server_replace_id. If the server that announces a channel
4015 to the router already exists in the router (with same name but
4016 with different Channel ID), router is responsible to send
4017 Replace ID packet to the server and force the server to change
4018 the Channel ID to the one router has.
4020 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4021 client that the Channel ID has been changed by the router. The
4022 normal server sends this to the client. Client must start using
4023 the new Channel ID as the channel's ID.
4025 Implemented handling of this new type into lib/silcclient/client.c
4026 into the function silc_client_notify_by_server.
4028 * Added new function silc_idlist_replace_channel_id into the files
4029 silcd/idlist.[ch] to replace the Channel ID.
4031 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Call silc_server_command_identify_check always when processing
4034 the IDENTIFY command in silcd/command.c
4036 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4039 send keepalive packets. The packet can be sent by clients,
4040 servers and routers.
4042 Added function silc_socket_set_heartbeat into the file
4043 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4044 If not set, the heartbeat is not performed. The actual
4045 heartbeat is implemented in the low level socket connection
4046 library. However, application is responsible of actually
4049 Added silc_server_send_heartbeat to send the actual heartbeat
4050 packet into silcd/packet_send.[ch]. Server now performs
4051 keepalive with all connections.
4053 * Added silc_task_get_first function into lib/silcutil/silctask.c
4054 to return the timeout task with shortest timeout. There was a bug
4055 in task unregistration that caused problems. TODO has been
4056 updated to include that task system must be rewritten.
4058 * The client library will now resolve the client information when
4059 receiving JOIN notify from server for client that we know but
4060 have incomplete information.
4062 * Rewrote parts of silc_server_remove_from_channels and
4063 silc_server_remove_from_one_channel as they did not remove the
4064 channel in some circumstances even though they should've.
4066 * Encryption problem encountered in server:
4068 The LEAVE command used to send the Channel Key packet to the
4069 router immediately after generating it. However, the code
4070 had earlier sent Remove Channel user packet but not immediately,
4071 ie. it was put to queue. The order of packets in the router
4072 was that Channel Key packet was first and Remove Channel User
4073 packet was second, even though they were encrypted in the
4074 reverse order. For this reason, MAC check failed. Now, this
4075 is fixed by not sending the Channel Key packet immediately but
4076 putting it to queue. However, this is more fundamental problem:
4077 packets that are in queue should actually not be encrypted
4078 because packets that are sent immediately gets encrypted
4079 actually with wrong IV (and thus MAC check fails). So, packets
4080 that are in queue should be encrypted when they are sent to
4081 the wire and not when they put to the queue.
4083 However, the problem is that the current system has not been
4084 designed to work that way. Instead, the packet is encrypted
4085 as soon as possible and left to the queue. The queue is then
4086 just purged into wire. There won't be any fixes for this
4087 any time soon. So, the current semantic for packet sending
4090 o If you send packet to remote host and do not force the send
4091 (the packet will be in queue) then all subsequent packets to the
4092 same remote host must also be put to the queue. Only after the
4093 queue has been purged is it safe again to force the packet
4096 o If you send all packets immediately then it safe to send
4097 any of subsequent packets through the queue, however, after
4098 the first packet is put to queue then any subsequent packets
4099 must also be put to the queue.
4101 Follow these rules and everything works fine.
4103 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Added new function silc_server_remove_clients_by_server to
4106 remove all client entries from ID list when the server connection
4107 is lost. In this case it is also important to invalidate all
4108 client entires as they hold the invalid server entry. This
4109 fixes fatal bug when server has lost connection and will reconnect
4112 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Made some sanity checks to silc_server_daemonise like to check
4115 whether the requested user and group actually exists.
4117 * Added sanity check to SKE's silc_ske_responder_finish to check
4118 that the public and private key actually is valid.
4120 * Invalidate the client's nickname when receiving Replace ID
4121 packet and the Client ID is being replaced. This means that the
4122 server will query the nickname if someone needs it (client)
4125 * Sort the ID Cache in client library when the ID Cache data
4126 has changed (needs sorting).
4128 * Do not allow for SILC client to create several connections to
4129 several servers. The client does not support windows right now
4130 and generating multiple connections causes weird behaviour.
4132 Irssi-silc client does support windows and can handle several
4133 connections without problems, see: www.irssi.org and SILC plugin.
4135 * Fixed some places where client was added to the IDList. The
4136 rule of thumb is following (in order to get everything right):
4137 If the client is directly connected local client then the
4138 `connection' argument must be set and `router' argument must be
4139 NULL to silc_idlist_add_client function. If the client is not
4140 directly connected client then the `router' argument must
4141 bet set and the `connection' argument must be NULL to the
4142 silc_idlist_add_client function.
4144 * The funtion silc_server_packet_send_local_channel actually did
4145 not check whether the client was locally connected or not. It
4146 does that now. Fixed a bug related to LEAVE command.
4148 * Fixed Remove Channel User payload parsing bug in server's
4149 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4151 * The server's silc_server_save_channel_key now checks also the
4152 global ID list for the channel as it might not be in the local
4153 list. Fixed a bug related to LEAVE command.
4155 * Is this the end of the [<unknown>] buglet that has been lurking
4156 around for a long time? A little for loop fix in server's
4157 silc_server_command_whois_parse that is used by both IDENTIFY
4158 and WHOIS command. At least, this was a clear bug and a cause
4159 of one type of [<unknown>] buglet.
4161 * WHOIS and IDENTIFY commands call the function
4162 silc_server_command_[whois/identify]_check function even if
4163 we are not router server.
4165 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Added --with-gmp configuration option. If set the GMP
4168 is always compiled in the SILC source tree. If not set then
4169 it is checked whether the system has the GMP3 installed. If
4170 it has then the GMP won't be compiled (the system's headers
4171 and library is used), if it doesn't have it then the GMP is
4172 compiled in the SILC source tree.
4174 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Changed RSA private exponent generation to what PKCS #1
4177 suggests. We try to find the smallest possible d by doing
4178 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4179 not security fix but optimization.
4181 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Added new config entry [Identity] to fork the server and run
4184 it as specific user and group. A patch from Bostik.
4186 * Imported Dotconf configuration library into lib/dotconf.
4187 This will be used to create the SILC configuration files later.
4188 It will appear in the distsribution after this commit.
4190 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * A big code auditing weekend happening. Auditing code for
4193 obvious mistakes, bugs and errors. Also, removing any code
4196 Removed files for being obsolete:
4198 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4199 inline in the file lib/silcutil/silcbuffer.h)
4201 o lib/silcutil/silcbufutil.c (the header has inline versions)
4203 Changed code to fix possible error conditions:
4205 o The buffer formatting routines now check that the destination
4206 buffer really has enough space to add the data. This applies for
4207 both buffer formatting and unformatting
4208 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4209 unformatting was changed to accomodate following rules:
4210 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4211 sent to the function while XXX_*STRING will not allocate or copy
4212 the data into the buffer. Instead it sets the pointer from the
4213 buffer into the pointer sent as argument (XXX_*STRING used to
4214 require that the pointer must be allocated already). This change
4215 makes this whole thing a bit more consistent and more optimized
4216 (note that the data returned in the unformatting with XXX_*STRING
4217 must not be freed now). The routines return now -1 on error.
4219 o Tried to find all code that use buffer_format and buffer_unformat
4220 and added return value checking to prevent formatting and
4221 especially unformatting errors and possible subsequent fatal
4224 o Changed ske->x and ske->KEY to mallocated pointers in
4225 lib/silcske/silcske.h. Fixed possible data and memory leak.
4227 o Added return value checking to all *_parse* functions. Fixed
4228 many memory leaks as well.
4230 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4231 so that buffer overflows would not happen. All code now also
4232 checks the return value as it can fail.
4234 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Added reconnection support to server if the normal server looses
4237 its connection to the router (for example if router is rebooted).
4238 The server performs normal reconnection strategy implemented
4239 to the server. Affected file silcd/server.c.
4241 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Added new packet type SILC_PACKET_SET_MODE that is used to
4244 distribute the information about changed modes (for clients,
4245 channels and clients channel modes) to all routers in the
4246 network. Updated the protocol specification accordingly.
4248 Added functions into silcd/packet_send.c and
4249 silcd/packet_receive.c: silc_server_send_set_mode,
4250 silc_server_set_mode.
4252 Added new files silcmode.[ch] into lib/silccore that implements
4253 the encoding and decoding of Set Mode Payload. Added new type
4254 SilcSetModePayload. Moved the definitions of different modes
4255 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4257 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Oops, a little mistake in server's connection authentication
4260 protocol. The protocol is not ended with FAILURE but with
4261 SUCCESS if the authentication is Ok. :) Affected file is
4264 * Implemented NICK_CHANGE notify handling in server in the file
4265 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4266 the local clients on the channel. After the changing nickname
4267 in router environment snhould work and the [<unknown>] nickname
4268 should appear no more.
4270 The silc_server_replace_id function that receives the Replace ID
4271 payload now sends the NICK_CHANGE notify type also in the file
4272 silcd/packet_receive.c
4274 * Changed WHOIS and IDENTIFY command to support the maximum amount
4275 of arguments defined in protocol specs (3328 arguments). This
4276 fixed a bug that caused problems when there were more than three
4279 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4281 * Added extra parameter, command identifier, to the
4282 silc_client_send_command so that explicit command identifier
4285 Changed that ID list routines uses specific command identifier
4286 when sending WHOIS/IDENTIFY requests to the server so that they
4287 can be identified when the reply comes back.
4289 Affected files lib/silcclient/command.[ch],
4290 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4292 * Added `sender' argument to silc_server_packet_send_to_channel
4293 to indicaet the sender who originally sent the packet to us
4294 that we are now re-sending. Ignored if NULL. Affected file
4295 silcd/packet_send.[ch].
4297 * Added some server statistics support in silcd/server_internal.h
4298 SilcServerStatistics structure and around the server code. Also
4299 send some nice statistics information when client is connecting
4302 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Fixed channel ID decoding in server's JOIN command reply in
4305 silcd/command_reply.c
4307 * Fixed braodcasting of replace ID payload to not to send it if
4308 we are standalone server in silcd/packet_receive.c.
4310 * Fixed all channel message sending routines to not to send
4311 packets to clients that has router set, since they are routed
4312 separately in the same function earlier. Affects file
4313 silcd/packet_send.c and all channel packet sending functions.
4315 * In USERS reply, res_argv[i] are not allocated, the table
4316 is allocated. Thus changed that free the table, not its
4319 * In server's whois_check and identify_check if the client is
4320 locally connected do not send any WHOIS commands - they are not
4323 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Fixed some minor bugs in client when sending WHOIS command. The
4326 arguments was in wrong order.
4328 * Removed statis function add_to_channel from server in
4329 silcd/command.c that was previously used with the joining but
4332 * Tested USERS command in router environment successfully with two
4333 routers, two servers and two clients.
4335 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Reorganized the USERS command and command reply in client library
4338 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4339 When the command is given by user we register a pending command
4340 callback that will reprocess the command after the reply has been
4341 received from the server. When reprocessing the packet we then
4342 display the information. Thus, the USERS information is displayed
4343 now in the command callback instead of in the command reply
4344 callback. The processing of the command is same as previously
4345 when server has sent the command reply in the JOINing process.
4347 * Added to USERS command in silcd/command_reply.c to join the client,
4348 we didn't use to know about, to the channel after we've created
4349 a client entry for it. Also, for clienet we did know already still
4350 check whether it is on the channel or not and add it if not.
4352 * Removed silc_server_command_join_notify as the function and its
4355 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Changed the client's pending command handling to the same as the
4358 server's pending command handling. It is also now possible to
4359 execute command reply functions from other command reply
4360 function as the function callbacks for commands and command
4361 replies are one and same. The pending commands are not static
4362 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4363 in client connection context. Thus, pending commands are server
4364 connection specific as it is convenient.
4366 Changed the function silc_client_command_pending and
4367 silc_client_command_pending_del and added new function
4368 silc_client_command_pending_check. Removed the
4369 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4372 * Added cmd_ident, current command identifier, to the client
4373 connection context in lib/silcclient/client.h to keep track on
4374 command identifiers used in command sending. Client's command reply
4375 function handling now supports the mandatory command identifiers.
4377 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4378 funtions in client to fully support pending command callbacks.
4380 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4381 as one of the arguments to the application in the command reply
4384 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4385 before first releasing SILC but came back. Now it is removed again
4386 and should come back nomore. The FORWARDED flag was used only
4387 by the JOINing procedure by forwarding the command packet to router.
4388 Now, the JOINing procedure has been changed to more generic (due
4389 to various router environment issues) and FORWARDED is not needed
4390 anymore for anything. The protocol specification is yet to be
4393 Now, removed silc_server_packet_forward from server and the flag
4394 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4396 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Renamed NAMES command to USERS command. The NAMES was named that
4399 due to historical reasons. Now it is renamed. Also, rewrote
4400 parts of the USERS command. The nickname list is not sent anymore
4401 by the server. Only Client ID and mode lists are sent in the USERS
4402 command. Changed this also to the protocol specification.
4404 The client now resolves the names and stuff after it receives
4405 the USERS list from the server when joining to the channel.
4407 * WHOIS and IDENTIFY commands has been changed to support multiple
4408 Client ID's per command. One can now search for multiple users
4409 in the network by sending only one WHOIS or IDENTIFY command.
4410 Changed the code and the protocol specifications.
4412 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4413 uses silc_server_command_whois_parse to parse the request. */
4415 * If normal server, do not parse the WHOIS and IDENTIFY requests
4416 before sending it to the router. Saves some time.
4418 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Fixed JOIN command on client library. Wrong number of arguments
4421 used to crash the client.
4423 * Added silc_server_channel_has_global function to check whether
4424 channel has global users or not.
4426 * Added silc_server_channel_has_local function to check whether channel
4427 has locally connected clients on the channel.
4429 * The silc_server_remove_from_one_channel now checks whether the
4430 channel has global users or not after given client was removed from
4431 the channel. It also checks whether the channel has local clients
4432 on the channel anymore. If it does not have then the channel entry
4433 is removed as it is not needed anymore.
4435 * The silc_server_notify now checks on JOIN notify whether the joining
4436 client is one of locally connected or global. If it is global then
4437 the channel has now global users on the channel and that is marked
4438 to the channel entry. Also, it now saves the global client to
4439 global list who is joining and JOINs it to the channel. This is
4440 for normal server, that is.
4442 Changed silc_server_send_notify_on_channel,
4443 silc_server_packet_relay_to_channel and
4444 silc_server_packet_send_to_channel check if we are normal server
4445 and client has router set (ie. global client) do not send the
4446 message to that client, as it is already routed to our router.
4448 * Implemented LEAVE notify type handling in silc_server_notify
4451 * Tested LEAVE command in router environment successfully. Tested
4452 with two routers, two servers and two clients.
4456 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4458 * Implemented SIGNOFF notify type handling in silc_server_notify
4461 * silc_server_remove_id now removes the client entry from all channels
4462 it has joined and thusly sends SIGNOFF notify type.
4464 * Rewrote the NAMES list generation in server by removing two excess
4465 loops. The lists are created now inside one loop.
4467 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * silc_server_remove_channel_user checks now also global list
4470 for channel and client.
4472 * silc_server_new_channel_user checks now both local and global
4473 list for channel and client. Fixed a bug in client id decoding.
4474 Used to decode wrong buffer.
4476 * silc_server_channel_message checks now both local and global
4477 list for channel entry.
4479 * Tested channel joining (hence JOIN) in router environment
4480 successfully. Tested with two routers, two servers and two
4483 * Tested channel message sending in router environment successfully.
4485 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Added silc_server_save_channel_key into server.[ch] to save the
4488 received channel key in Channel Key payload processing. It is
4489 also used in JOIN command reply handling.
4491 Equivalent function silc_client_save_channel_key added into
4492 client.[ch] into client library.
4494 * Changed JOIN command reply to send information whether the channel
4495 was created or not (is existing already) and the channel key
4496 payload. Changed protocol specs accordingly.
4498 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4499 the request was sent by ID and not by nickname. Crashed on
4502 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4505 now correctly save the received data.
4507 * silc_server_free_sock_user_data now notifies routers in the
4508 network about entities leaving the network.
4510 At the same time implemented functions silc_server_remove_id
4511 and silc_server_send_remove_id to receive and send REMOVE_ID
4512 packets. The packet is used to notify routers in the network
4513 about leaving entities. The ID removed will become invalid in
4516 * Added function silc_idlist_del_server into server. Removes and
4517 free's server entry from ID list.
4519 * silc_server_private_message function now checks, if we are router,
4520 that the destination ID really is valid ID, naturally.
4522 * In router when NEW_ID packet is received (for new client) the
4523 hash of the Client ID is saved in the ID Cache but the
4524 client->nickname is set to NULL, instead of putting the hash
4527 IDENTIFY command now also checks that client->nickname must be
4528 valid. If it is not if will request the data from the server who
4529 owns the client. Added new function
4530 silc_server_command_identify_check.
4532 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4533 to set the command to already allocated Command Payload.
4535 * Tested private message sending in router environment with two
4536 routers, two servers and two clients. Fixed minor bugs and now
4539 * Fixed segfault from client's NAMES command. Used to crash if
4542 * Forwarded packets must not be routed even if it is not destined
4543 to the receiver. Changed server code comply with this.
4545 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Added `require_reverse_mapping' boolean value to ServerParams
4548 structure. If TRUE (not default) the server will require that
4549 the connecting host has fully qualified domain name.
4551 If the reverse mapping is not required and hostname could not be
4552 found the IP address is used as hostname.
4554 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Implemented version string checking to both client and server.
4557 The check is incomplete currently due to the abnormal version
4558 strings used in development version of SILC.
4560 * Changed all command functions in server to use the new
4563 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Changed char *data to unsigned char *data in ID Cache system to
4566 support binary data as ID Cache data. Changed code to support
4567 binary data in lib/silccore/idcache.c.
4569 * Renamed silc_server_packet_relay_command_reply to
4570 silc_server_command_reply as it is normal packet receiving
4571 function. Rewrote the function to accept command replys for
4572 servers and not only for clients.
4574 * Mark remote router always as registered server if we are connecting
4575 to it. Otherwise, commands sent by the router to us are ignored.
4577 * All ID List find routines now returns the ID Cache Entry pointer
4578 as well if requested.
4580 * WHOIS command works now in router environment, tested with two
4581 routers, two servers and two clients.
4583 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4584 in router environment (as it is almost equivalent to WHOIS) but
4585 hasn't been tested thoroughly. Added new functions:
4587 silc_server_command_identify_parse
4588 silc_server_command_identify_send_reply
4589 silc_server_command_identify_from_client
4590 silc_server_command_identify_from_server
4592 * Disabled route cache adding because adding two different ID's with
4593 same IP replaces the old cache entry thus giving wrong route.
4594 The entry->router->connection is always the fastest route anyway
4595 so route cache may not be needed. Of course, new routes maybe
4596 established after receiving the ID when the entry->router->connection
4597 might not be anymore the most optimal.
4599 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Add route cache for received ID for fast routing.
4603 * Added silc_server_packet_route to route received packet on router
4604 that is not destined to us.
4606 * Renamed silc_server_get_route to silc_server_route_get.
4608 * Added id_string and id_string_len fields into SilcServer to
4609 include encoded ServerID for fast comparing without excess
4610 encoding of the ID's.
4612 * Cleaned up WHOIS command on server side. Added following static
4615 silc_server_command_whois_parse
4616 silc_server_command_whois_check
4617 silc_server_command_whois_send_reply
4618 silc_server_command_whois_from_client
4619 silc_server_command_whois_from_server
4621 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4622 arguments in command replies. All command functions should be
4623 updated to use this macro.
4625 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Minor typo fixes on command reply handling on server.
4629 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added silc_server_command_add_to_channel internal routine to add
4632 the client to the channel after router has created the channel and
4633 sent command reply to the server.
4635 * Added generic silc_server_send_command to send any command from
4638 * Use static buffer with ID rendering instead of duplicating data.
4640 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Fixed a channel user mode bug when joining to a channel server gave
4643 everybody channel founder rights, oops.
4645 * We mark ourselves as the router of the incoming server connection
4646 if we are router ourselves. This way we can check in some packet
4647 sending functions whether it is locally connected server. For
4648 incoming router connections we put NULL.
4650 * For router sending packets locally means now always sending the
4651 packet cell wide; to local clients and local servers. For normal
4652 server sending packet locally means sending it to only local
4655 * Fixed the JOIN command to really work in router environment. If the
4656 channel is created it is always created by the router. Router is
4657 also responsible of making the initial joining to the channel,
4658 sending JOIN notify to the sending server and distributing
4659 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4660 does not exist server doesn't do anything else but forward the
4661 command to the router which performs everything.
4663 * Added silc_server_send_channel_key function to send the Channel Key
4666 * Added silc_server_create_channel_key to create new channel key. The
4667 channel key is now re-generated everytime someone joins or leaves
4668 a channel, as protocol dictates. Note: channel->key_len is the
4671 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4674 packet_receive.[ch] to separate packet sending and receiving
4675 routines. The server.[ch] now includes everything else including
4676 actual packet processing (writing and reading data) and other
4679 Renamed silc_server_private_message_send_internal to
4680 silc_server_send_private_message. The routine is still though
4681 used only to relay private messages as server does not send
4682 private messages itself.
4684 Renamed silc_server_new_channel to silc_server_create_new_channel
4685 and added new function sicl_server_new_channel that handles the
4686 incoming New Channel packet. Added also new sending function
4687 silc_server_send_new_channel to send New Channel Payload.
4689 * Added new function silc_server_notify to process incoming notify
4690 packet to the server/router. Server may then relay the notify
4691 to clients if needed.
4693 * Added new function silc_server_new_channel_user to process incoming
4694 New Channel User packet. Router will redistribute the packet and
4695 send JOIN notify to its local clients and locally connected servers
4696 if needed. Normal server will send JOIN notify to its local client
4697 on same channel when received this packet. Added also corresponding
4698 sending function silc_server_send_new_channel_user to sent the
4701 * Added boolean route argument to send_notif_to_channel and
4702 packet_send_to_channel functions to attempt to route the packet
4703 if it is TRUE and send only locally if it is FALSE.
4705 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * silc_server_replace_id now broadcasts the received replace ID
4708 packet if it is not broadcast packet already. The router must
4709 broadcast to inform other routers about changed ID.
4711 * Added backpointer to server's router into SilcServer context in
4712 silcd/server_internal.h.
4714 * Fixed silc_server_packet_broadcast to send correct broadcast
4717 * The channel key is now distributed to the local client as soon
4718 as it is received from the router (in router environment) so that
4719 no other packet may be sent for the channel until client has
4722 * silc_server_remove_channel_user now broadcasts the received
4723 Remove Channel User packet if it is not broadcast packet already.
4724 The router must broadcast to inform other routers about removed
4727 * Added users field into SilcPacketContext that is a reference count
4728 of the context. One can increase the reference count by calling
4729 silc_packet_context_dup which is now changed to just increase the
4730 reference count instead of duplicating the data. The reference
4731 count is decresed by calling silc_packet_context_free that will
4732 free the data after the reference count hits zero.
4734 For now on the packet context and everything allocated into it
4735 (including the raw packet from network) must be freed by calling
4736 the new silc_packet_context_free function. Added also new function
4737 silc_packet_context_alloc that must be used now to allocate the
4738 context. This also means that if a routine is asynchronous from
4739 silc_[client/server]_packet_parse_type the packet context must
4740 be duplicated by calling silc_packet_context_dup. Otherwise it
4741 gets free'd after silc_[client/server]_packet_parse_type returns.
4742 Also, one must remember that if packet is duplicated then its
4743 reference count must be decresed by calling the free function as
4744 many times as it was duplicated.
4746 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4747 from both client and server.
4749 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Made joining to a channel working in router environment.
4753 * Cleaned up JOIN command on server side and create function
4754 silc_server_command_join_channel internal routine to make the
4757 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Changed silc_command_pending list to SilcDList. Also, added
4760 `ident' field to SilcServerCommandPending structure to identify
4761 the reply and to call correct callback.
4763 Added silc_server_command_pending_check function to replace the
4764 corresnponding macro. The silc_command_pending list is not
4767 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4768 to set identifier to previously allocated Command Payload. It
4769 is used to set identifier for command when resending Command
4772 * Added silc_command_payload_encode_payload to encode Command
4773 Payload buffer from SilcCommandPayload structure.
4775 * Added silc_argument_payload_encode_payload to encode Argument
4776 payload buffer from SilcArgumentPayload structure.
4778 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Changed WHOIS command to support router connection on server side.
4781 The whois request is always sent to router unless the server is
4782 standalone server. After server has received the reply from the
4783 router will it send the reply to the client.
4785 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4786 broadcast received broadcast packet. The function is used only
4787 by router. The broadcast packet is always sent to the router's
4790 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4791 render given ID to printable string, for log files for example.
4793 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Made basic router to router connections working. At least they
4796 can now connect to each other but nothing really works the way
4797 they are supposed - yet.
4799 * Added new initiator token to RouterConnection configuration
4800 file in silcd/serverconfig.[ch]. It is used to tell whether we
4801 are the initiator to the remote router or whether we'll expect
4802 the other end to connect.
4804 * Moved registering of listener task to silc_server_init, hence
4805 the server starts listenning as soon as it is run, even if it
4806 does not have connections to other routers. Let's see how well
4809 * Changed default connection retry timeouts for more suitable in
4812 * Removed cipher and such arguments from silc_idlist_add_client
4813 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4814 Added new function silc_idlist_add_data to add the keys and stuff
4817 * Added SilcIDListData structure and added it to SilcClientEntry
4818 and SilcServerEntry as their first field in the structure. This
4819 way we can explicitly cast the ID entries to the SilcIDListData
4820 structure and get common data for the entries. In past, we had
4821 to first check what type of connection it is and then cast it to
4822 correct ID entry type. Now, we can directly cast the opaque
4823 pointer to the SilcIDListData (no matter what ID entry it actually
4824 is) and get the data needed.
4826 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4829 in some circumstances even if threre were timeout tasks, though not
4830 IO tasks, but tasks anyway. Now fixed.
4832 * Defined SilcServerConnection structure to hold connection specific
4833 stuff about directly connected servers and routers. The definition
4834 is currently in silcd/server_internal.h. I thought about having
4835 a bit more important role fro this struct but for now it is used
4836 only when connecting to other server (or router actually).
4838 * Added connecting retry support in server when connecting to
4839 router(s). The retry feature implement exponential backoff
4840 algorithm. Also, added SilcServerParams structure to hold default
4841 parameters for server. For now, it include these retry settings
4842 and are hard coded. After server is moded to be as Silc Server
4843 Library this structure will be more important.
4845 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Changed client librarys channel->clients table to SilcList and
4848 changed code accordingly.
4850 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Changed client's channel table to SilcList and changed code
4853 accordingly. Also changed SilcChannelClientEntry to include back-
4854 pointer to the channel so that client entry can use that structure
4855 as list as well and we have fast cross-reference to the channel.
4856 This change dramatically decreased the complexity of channel
4857 handling with client entry and vice versa (removed one extra
4858 loop when searching for channel entry from many functions).
4860 * Changed server->sim from table to SilcDList and changed code
4863 * NAMES command can now be used from user interface. It will show
4864 the user list on the channel, neatly.
4866 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4867 Code now saves realname of the user if it becomes available.
4869 * Renamed configure.in to configure.in.pre and made ./prepare
4870 script to automatically add correct version string to
4871 configure.in which it creates from configure.in.pre.
4873 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * NAMES command reply now shows users mode with the nickname when
4878 * Moved silc_client_ch[u]mode[_char] functions from
4879 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4880 place sucks, they are utility functions and should be in some
4883 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4885 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4888 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added TRQ (efficient deque and list library) into lib/trq. This is
4893 a very good list library that is currently used in the SILC. Defined
4894 SilcList API over the library because I didn't like the API very
4895 much. See lib/trq/silclist.h for the API and examples of how to
4896 use the API. Fixed various places in the code to use the new
4897 SilcList API. The SilcList is meant for lists that has a structure
4898 already defined as a list. It is not suitable to add just some
4899 context to the list (in TRQ, the context is the list actually).
4901 So, I defined SilcDList that can be used for the purpose where
4902 predefined list structure does not exit. This can be used as
4903 such list. Now some context just can be added to the SilcDList.
4904 Currently this list is not used in the SILC just yet, though there
4905 are a lot places where this can replace dynamically allocated
4906 tables and I will fix these places, later, to use SilcDList.
4907 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4908 and use TRQ internally).
4910 Also fixed some annoying warning messages that the original TRQ
4911 code generated. Also minor changes to TRQ's Makefile.in.
4913 * Added support for querying by Client ID to both WHOIS and
4914 IDENTIFY commands into server, as required by the protocol.
4916 * Removed method function pointers from SilcBuffer structure. They
4917 weren't used to anything and just increased the context size for
4918 no good reason. This change also made silc_buffer_alloc and
4919 silc_buffer_free functions inline functions.
4921 * Disabled command flooding detection support until it's fixed so
4922 that it accepts commands in but does not execute them more than once
4925 * Added silc_net_localhost(), to return local hostname, into
4926 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4927 that must be initialized before calling silc_client_init.
4929 * Added new function: silc_server_send_notify_on_channels to send
4930 notify messages to all channels client has joined. It is assured
4931 that the message is sent only once per client.
4933 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4934 lib/silcutil/silcutil.[ch] as silc_format function. The new
4935 function is generic and is used by server as well, not only by
4936 the logging routines.
4938 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4939 the provided version string was not acceptable. Added new function:
4940 silc_ske_check_version into lib/silcske/silcske.h. The function
4941 must be implemented by the application (client or server) and it
4942 does not reside in the SKE library. The function checks the version
4943 string remote end sent.
4945 * Added back pointers (to opaque context and to SilcSocketConnection)
4946 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4948 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4949 duplicate packet context structure.
4951 * Changed `notify' client operation to send same arguments as client
4952 receives from server except for ID's. ID's are mapped to correct
4953 ID entry and that is returned. Also, if channel entry is not sent
4954 by server but the notify is for channel the channel entry is sent
4955 to application (otherwise application doesn't know that it is for
4956 channel (library gets it from packet's Destination ID)).
4958 * Added silc_client_remove_from_channels into client library to
4959 remove a client from all channels it has joined to. Used when
4960 received SIGNOFF notify from server. Added also new function
4961 silc_client_replace_from_channels to replace old ID entry with
4962 new ID entry on all channels. Used when received NICK_CHANGE
4965 * Fixed ID Cache list handling in silc_idlist_get_client in
4966 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4967 to get (or query) client by ID.
4969 * Updated TODO list.
4971 * Added connection authentication status message defined by the
4972 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4973 support for these into the code in client and server side.
4975 * Added generic function silc_client_send_command to send any command
4976 with variable argument list. Application should use this function
4977 to send commands if the command functions provided by the library
4978 does not suite for the application's user interface needs.
4980 * Added new `failure' client operation. Application is notified about
4981 received failure packet if client is executing a protocol. In this
4982 case the protocol's execution has failed.
4984 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4985 is required by the protocol.
4987 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4988 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4991 * Added status flag to SilcSKE object to indicate realtime status
4992 of the SKE protocol.
4994 * Application receives now exactly same command reply arguments as
4995 the library receives from server. However, if ID is received the
4996 corresponding ID entry is returned to the application (eg. Client
4997 ID is mapped to correct SilcClientEntry entry and that is returned).
4998 Changed command_reply client operation due to this change.
5000 * Changed all ID's in commands and in command replys as ID Payloads.
5001 Change affected both client and server side codes.
5003 All ID's sent in SILC network (with execption of ID's in SILC
5004 Packet header) are sent in ID Payload to support variable length
5007 * Server now notifies nick changes and notifies all clients on
5008 the channels about the new nickname (about the new Client ID,
5011 * Implemented CMODE command to change channel modes. Supports all
5012 channel modes defined by the protocol specs except ban and invite
5013 lists. (Also, private channel key mode is supported but support for
5014 setting private channel key in client is missing, thus, this mode
5015 has no effect on client side (except that server requires that the
5016 client uses private channel key and normal channel traffic does not
5019 Also, invite mode works per se, but INVITE command does not work
5020 yet correctly, so you can set channel as invite only channel but
5021 inviting clients to the channel does not work (it is yet to be
5022 thought what's the best way to do it).
5024 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5025 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5026 Implemented CUMODE command to change user's mode on the channel.
5027 Supports all modes defined by the protocol specs.
5029 * Added NAMES command reply to return users modes on the channel.
5031 * Removed unnecessary and slow ciphers from lib/silccrypt.
5033 * Set SO_KEEPALIVE option to connection sockets by default.
5035 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5037 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5038 redefined the Notify Payload into protocol specs.
5040 * Added silc_id_payload_parse_id to get ID directly from raw
5043 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5046 accept searching by Client ID as well.
5048 * Added support for LEAVE and SIGNOFF notify types in client library.
5050 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5051 to parse ID Payload from raw data.
5053 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Added flags parameter into silc_ske_assemble_security_properties
5056 function in lib/silcske/silcske.[ch].
5058 * Changed notify client operation to fit better for notify messages
5059 sent by server. The notify payload received from server is now
5060 passed to the application (after parsing it to SilcNotifyPayload).
5061 It is application's responsibility to retrieve the arguments
5062 from the payload and show the message the way it wants. The message
5063 sent by server is implementation specific.
5065 * Changed public keys to comply with the protocol specification.
5066 Old public keys are not supported anymore and are not compatible.
5068 * Removed nickname from Channel Payload as the latest draft removed
5069 it. The client must resolve the nickname from the NAMES command
5070 reply received when it joined the channel.
5072 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5074 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Fixed some errors in protocol specification drafts.
5078 * Created lib/silccore/silcnotify.c to implement Notify Payload
5079 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5080 generic payloads described by protocol specifications. The file
5081 includes implementations for ID Payload and Argument Payload.
5083 * Changed Command Payload implementation to use the new Argument
5084 Payload. Changed command_xxxx_payload to command_payload_xxxx
5085 to comply with SILC coding conventions.
5087 * Added suppport for Argument Payload handling in Notify Payload
5088 implementation as protocol requires it. Added the new support
5089 into server and client lib as well.
5091 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added support for multiple nicknames on same channel. [n] is
5094 added locally to the nickname if there are more than one same
5095 nicknames on the channel.
5097 * Server now sends all nicknames that matched WHOIS request.
5098 Client also shows the list received from server.
5100 * Added TOPIC command to client side. User can now set and show
5101 current topic on channel.
5103 * Added MOTD command to client and server. Also, server sends the
5104 motd when client connects to the server.
5106 * Changed version strings to comply ISO 8601.
5108 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Fixed protocol error handling in client library. It should now
5111 cope even if the SKE fails for some reason.
5113 * Made new protocol specification drafts for submitting to IETF.
5115 * Implemented TOPIC command to server in silcd/command.c.
5117 * Added two new notify types into lib/silccore/silcnotify.h:
5118 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5119 notify nickname change and topic setting/change on a channel.
5121 * API change of command_reply operation in client library. The
5122 application gets now the status type received from server as well.
5124 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5128 * Cras fixed and optimized the packet handling even further and
5129 it should work now. Minor change to the prototype of function
5130 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5132 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Added new function into lib/silcutil/silcschedule.[ch]:
5135 silc_schedule_with_fd to select() a specified fd. The function
5136 returns after timeout expires or data arrives or goes. The
5137 function is used by packet routines to wait that all data is
5138 received from network.
5140 * Fixed data reading from network in lib/silccore/silcpacket.c.
5141 The code now assures that all data is read from the fd and then
5142 continues packet processing. This was a bug fix since the code
5143 used to drop some data in some circumstances.
5145 * Added new function into lib/silcclient/client.[ch]:
5146 silc_client_start_key_exchange to start key exchange after
5147 connection has been established to server. The code internally
5148 now uses this funtion but its main purpose was to provide it
5149 for applications that perform their own connecting. After
5150 application has created a connection it merely calls this
5151 function to start the key exchange between client and server.
5152 The library takes care of everything else after that.
5154 Updated also lib/silcclient/README to explain the usage of
5157 * Do not send to application information that connection has
5158 been established. Application gets notified it by connect
5161 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Applied cras's patch to add silc_schedule_one function. The
5164 function runs scheduler once and returns.
5166 * Fixed the scheduler after cras messed it up. The timeout
5167 handling works now as it's supposed to work.
5169 * Added into lib/silccore/ silcnotify.h to include notify
5170 message types support. Changed silc_server_send_notify*
5171 functions, in server.[ch], to support those new notify types.
5172 Added the support for the notify types into client library,
5173 as well. Added new notify client operation into ops.h in
5176 * Changed silc_server_packet_send_to_channel to send normal
5177 packets instead of just channel message packets. The function
5178 is now used to send the notify packets to channels. It is not
5179 used to send channel message packets anymore, as server never
5182 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5183 va_arg()s as it seems to require it nowadays. I guess, if SILC
5184 is compiled with older va_arg() the new code should work anyway.
5186 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Splitted core library. Core library (lib/silccore) includes
5189 now only SILC protocol specific core (and common) components.
5190 Created new utility library (lib/silcutil) that includes more
5191 generic purpose stuff. The stuff for util library was taken
5192 from the old core library. This was minor and easy split.
5194 * Created SILC Client Library (lib/silcclient) that includes
5195 implementation of the SILC client without user interface. This
5196 was major move from silc/ directory. The code has been changed
5197 so that it is transparent towards the user interface. The
5198 silc/ directory includes now the same user interface as before
5199 and it uses the new client library. Read lib/silcclient/README.
5200 Basicly, the client library performs everything else related
5201 to SILC except user interface handling. Also, configuration
5202 files are considered to be part of user interface and library
5203 does not handle them.
5205 This change also changed a lot of structures, function naming etc.
5206 Most important change was that SilcClientWindow object was
5207 renamed to SilcClientConnection in the client library. Created
5208 also new file lib/silcclient/ops.h. Also added new files
5209 silc/local_command.[ch] and silc/client_ops.[ch].
5211 All these changes were made to make it easier for user interface
5212 designers to create what ever user interface for the SILC client
5215 It is also expected that the server will be moved to lib
5216 directory as well and SILC Server Library will be created;
5217 sometimes in the future.
5219 * Removed Local commands from lib/silccore/silccommand.h as
5220 they are application specific and new client library does not
5221 handle any of those anymore.
5223 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5224 old client implementation in silc/.
5226 * Added support for callback functions in SILC_LOG_* macros.
5227 Application can now set its own callbacks that will be called
5228 instead of using the default functions that will always print
5229 the debug messages to stderr (or stdout). Also, debugging can
5230 now be disabled by setting silc_debug to FALSE and re-enabled by
5231 setting it to TRUE. Note, that logging will still work even
5232 if debugging is disabled.
5234 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5235 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5236 silc_log_reset_debug_callbacks.
5238 * To enable debugging in silc client one must give now -d
5239 option on command line.
5241 * Changed silc_schedule_init to automatically allocate task queues
5242 if they are not allocated before calling it.
5244 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Added GMP 3.1 into math library.
5248 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5251 a channel in SILC network. The packet is used by servers and
5252 routers to notify other routers that user has left a channel.
5253 This little feature was missing until now. Added the feature
5254 to protocol specification as well.
5256 Added functions: silc_server_send_remove_channel_user and
5257 silc_server_remove_channel_user into server.[ch].
5259 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5260 lib/silccore/silcpacket.h. However, they are not implemented
5263 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Fixed joining to a channel and sending channel messages
5266 between server and router. The channel message sending should
5267 now work inside a cell.
5269 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Fixed the private message sending between server and router.
5272 The private message sending should now work inside a cell.
5274 * Added silc_server_replace_id into server.[ch] to replace
5275 existing ID in the SILC network.
5277 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5278 and silc_idlist_replace_server_id into idlist.[ch] in server.
5280 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Fixed the server to server connections. Server can again now
5283 connect to router. Router to router connections probably does
5286 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added dynamic protocol registering support. Now protocols can
5289 registered and unregistered on the fly. Patch by cras.
5291 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Added lib/contrib directory to hold routines that some platforms
5294 don't have but are needed by SILC.
5296 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5297 into lin/contrib to provide getopt() and getopt_long() for
5298 those who don't have it.
5300 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Added AWAY command to client. When away message is set and
5303 client receives a private message packet the client automatically
5304 replies to the sender with the away message.
5306 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5307 bug seemed to be the cause of recent problems when compiling
5310 * Added version detection support to SKE protocol specification
5311 and added the new changes to the SKE implementation as well.
5312 There were other minor changes in the SKE protocol as well.
5314 Many changes in lib/silcske/silcske.[ch] and in
5315 lib/silcske/payload.[ch].
5317 * Added ^U functionality, clear input line. Patch from cras.
5319 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Mainly small bugfixes on core library. Fixed some debugging
5322 logging and buffer overflow in silclog.c.
5324 * Updated config.sub and config.guess on the distribution tree.
5326 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Added command lagging support in server. Client may execute
5329 commands now only once in two seconds.
5331 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Optimized packet reception. MAC computation and checking is now
5334 also more optimized. A lot previously duplicated code is now
5335 used as generic by both client and server.
5337 * Fixed key pair generation in clientutil.c
5339 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Added into lib/silccore/silcbufutil.[ch] new function;
5342 silc_buffer_realloc.
5344 * Moved generic packet sending/encryption functions to
5345 lib/silccore/silcpacket.[ch] from client and server. Some
5346 rewriting of the functions.
5348 * Moved all generic packet reception/decryption functions to
5349 lib/silccore/silcpacket.[ch] from client and server. The
5350 packet processing is now much cleaner in both client and server.
5351 These were major changes in both client and server.
5353 * Created many common functions in server to do packet sending.
5354 Previously code were duplicated a lot, this has been removed
5357 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Rewrote major parts of the ID cache system. Don't know
5360 whether it is better now or not but at least the API is more
5363 * Major rewrite on ID cache stuff on client because of the ID
5364 cache API changes. Added idlist.c to client.
5366 * Also major rewrite on ID cache stuff on server as well.
5367 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5368 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5369 in hand, instead they are all put into the ID cache system now.
5370 All server_idlist_* routines uses ID cache now instead of
5371 traversing its own lists (those lists does not exist anymore).
5372 SilcIDList though still exists. Also, SilcXXXEntry's are
5375 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Finally made the SKE implementation compliant to the protocol
5378 specification. All mp integers are now binary encoded as
5379 opposed being HEX encoded.
5381 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5384 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5385 functions: silc_[encode/decode]_pem. Also added function
5386 silc_encode_pem_file to PEM encode with newlines ('\n') for
5389 * SILC public keys are now encoded either PEM or binary. Same
5390 option is for private keys as well. By default private keys
5391 are binary encoded and public keys PEM encoded. Silly HEX
5392 encoding were removed.
5394 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5395 function to create fingerprints.
5397 * Fixed a bug in SHA1; does not change the original data anymore.
5399 * Partly implemented INFO command on client and server side.
5400 Fixed CLEAR command. Changes to SERVER command; show current
5401 server(s) when giving command without arguments. Added
5402 VERSION command to client.
5404 * Added check to server that unregistered connections cannot
5405 execute commands (unless it is specificly allowed).
5407 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Fixed screen refresh.
5411 * Fixed channel joining bug from client. On some circumstances
5412 client tried to join to a channel it had already joined.
5414 * Added public key verification process into client's protocol.c.
5415 The client now verifies the public key from user and saves
5416 it into ~./silc/serverkeys/ directory.
5418 Added into: clientutil.[ch]: silc_client_verify_server_key.
5420 * Changed SKE protocol's silc_ske_initiator_finish function
5421 to accept callback function that verifies the received public
5422 key. Removed old silc_ske_verify_public_key function.
5424 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5427 silc_pkcs_private_key[_data]_set.
5429 * Made the password and public authentication more cleaner in
5430 server's protocol.c.
5432 * Removed historic and obsolete protocol `channel_auth' from
5433 both client and server.
5435 * Removed wrong way of sending command status messages from
5436 server to client in server's command.c. The old way violated
5437 protocol specification.
5439 Changes to silccore/silccommand.[ch]: removed
5440 silc_command_encode_status_payload -> not needed anymore,
5441 changed silc_command_encode_payload_va to accept extra
5442 argument on variable argument list. The argument type must
5443 now be provided to the function. Also, added new function:
5444 silc_command_encode_reply_payload_va which is same as
5445 normal command_encode_payload_va except command status type
5446 is provided as extra argument.
5448 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Added ~./silc directory handling. The directory includes the
5451 public and private keys for the client.
5453 Added silc_client_check_silc_dir, silc_client_create_identifier
5454 and silc_client_load_keys.
5456 * Implemented SILC protocol compliant public key. Added public
5457 and private key saving to and loading from files.
5459 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5460 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5461 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5462 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

5470 * Added silc_server_get_route (route.[ch]) to get connection
5471 data for the fastest route for given ID.
5473 * Implemented INVITE command on client and server. The command
5474 were re-defined in the SILC Protocol Specification and the
5475 implementation now complies with the specification.
5477 * Implemented PING command on client and server.
5479 * Implemented NAMES command on client and server. The server side
5480 supports currently only normal server not router server yet.

5487 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5488 again. This change was made to the protocol as well. Server
5489 should not violate the protocol specification anymore.

5493 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
