3 * Assure that silc_client_notify_by_server_resolve does not
4 resolve the client information multiple times. If it cannot
5 be found by the first it cannot be found at all. Affected
6 file lib/silcclient/client_notify.c.
8 * Fixed WHOWAS command reply calling. Affected file
9 lib/silcclient/command_reply.c.
11 * Removed all references to silc_idlist_get_client from the
12 Irssi SILC client since that call is internal call used by
13 the library. The Irssi SILC client will use now client
14 retrieval functions found in silcapi.h.
16 * Fixed a bug in resolving nickname info before sending
17 private message. It used freed memory. Affected file
18 irssi/src/silc/core/silc-servers.c.

39 * Added silc_net_localip to return local host's IP address.
40 Affected file lib/silcutil/silcnet.[ch].
42 * If key exchange or rekey protocol is active for a connection
43 parse all packets syncronously since there might be packets
44 in packet queue that we are not able to process without first
45 processing packets before them. Affected file silcd/server,
46 lib/silcclient/client.c.
48 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
49 whether library should continue processing the packet.
50 Affected file lib/silccore/silcpacket.h.
52 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

83 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Resolve the client info when received private message or
86 channel message for a client which nickname we don't know.
87 Affected files lib/silcclient/client_prvmsg.c and
88 lib/silcclient/client_channel.c.
90 * Do not crash in /KEY if client is not connected. Affected
91 file irssi/src/silc/core/silc-channels.c.
93 * Added SilcClientStatus field to the SilcClientEntry in the
94 lib/silcclient/idlist.h.
96 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
97 is incomplete and is being resolved, it won't be resolved
100 Make sure also that USERS command reply does not resolve
101 twice information. Affected file is
102 lib/silcclient/command_reply.c.
104 Make sure that silc_client_get_clients_by_list does not
105 resolve twice same information.
107 * Check for valid client->id in the silc_server_free_client_data.
108 Affected file silcd/server.c.
110 * Fixed /GETKEY nick@server not to crash if the server entry
111 is not found. Affected file lib/silcclient/command.c.

123 * Call the silc_server_udpate_servers_by_server in the
124 primary router that comes back online in the backup resuming
125 protocol. Otherwise it routes packets wrong. Affected file
126 silcd/server_util.[ch], silcd/server_backup.c.
128 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
131 lib/silcutil/silcbuffmt.[ch].
133 * Redefined the SILC packet header to include the padding
134 length. Affected file lib/silccore/silcpacket.[ch].
136 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
137 length for maximum padding up to 128 bytes). Affected
138 file lib/silccore/silcpacket.h.
140 * Removed all backwards support for old 0.5.x MAC thingies.
141 The SILC packet header change makes it impossible to be
142 backwards compatible.
144 * Send the ENDING packet with timeout in the backup resuming
145 protocol. This is to assure that all routers has connected
146 to the primary router. Affected file silcd/server_backup.c.
148 * Changed the RNG to take the first IV from random data. It
149 used to take it from zero actually. Changed the RNG also
150 to use /dev/urandom during session. /dev/random is used
151 in initialization. Affected file lib/silccrypt/silcrng.[ch].
153 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
155 * Changed the SILC packet header to have the first two bytes
156 (the packet length) encrypted. Affected files aroung the
157 code tree, lib/silccore/silcpacket.[ch]. Removed the
158 SilcPacketCheckDecrypt callback. It is not needed anymore
159 since the silc_packet_receive_process will determine now
160 whether the packet is normal or special.
162 * Implemented the unidirectional MAC keys. Affected files
163 lib/silcske/silcske.c, silcd/protocol.c and
164 lib/silcclient/protocol.c.
166 * Implemented the packet sequence number to the MAC computation.
167 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
168 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
169 lib/silcclient/protocol.c.
171 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
173 * Allow backup router to announce servers. All servers
174 announced by backup router are added to the global list
175 automatically. Update hte server's socket to our primary
176 router also when backup router announces a server.
177 Affected file silcd/packet_receive.c.
179 * Do not update the client->router in the function
180 silc_server_udpate_clients_by_server if the client is on
181 global list. We might fail to find any specific server
182 for locally connected clients and local cell clients. They
183 should still use the `from' and not `to' as client->router.
184 This fixes backup router resuming protocol. Affected file
187 * Decrease channel statistics count only if the channel
188 deletion worked. Affected files are silcd/server.c and
191 * Added silc_server_update_servers_by_server to update origin
192 of all server entries. Used during backup router protocol.
193 Affected files silcd/server_util.[ch], silcd/server.c. and
194 silcd/backup_router.c.
196 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
197 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
198 silc_hmac_get_hash and silc_hmac_get_name. Affected file
199 lib/silccrypt/silchmac.c.
201 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
203 * Assure that router cannot reroute the same channel message
204 to the sender. Affected file silcd/packet_receive.c.
206 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Made better checks that the channel message is not sent
209 to the router it came from. Affected file is
210 silcd/packet_send.c. Fixed memory leak too.
212 * Announce informations for incoming router connection, but
213 only after checking if it is replaced by backup router.
214 Affected file silcd/packet_receive.c.
216 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Fixed the backup resuming protocol to work in multiple
219 router environment. Affected file silcd/server_backup.c.
221 * Route packet only to one router in the function
222 silc_server_packet_send_to_channel. Affected file is
225 * Fixed silc_server_send_notify_dest to set the broadcast
226 flag. Fixed the silc_server_send_notify_topic to actually
227 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
228 Affected file silcd/packet_send.c.
230 * Changed the SFTP Filesystem interface. Changed the
231 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
232 the filesystem operation function. The SilcSFTPFilesystem
233 is now a context that is allocated by all filesystem allocation
234 functions and it already includes the operations structure
235 and filesystem specific context. It is given as argument
236 now to the silc_sftp_server_start. This made the interface
237 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
238 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
240 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
242 * Changed the backup router adding and getting interfaces
243 in the server. The router that will be replaced by the
244 specified backup router is now sent as argument. Affected
245 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
248 * Added silc_net_addr2bin_ne to return the binary form of
249 the IP address in network byte order. Affected files
250 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
252 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Check for existing server ID in silc_server_new_server
255 and in silc_server_connect_to_router_final and remove the
256 old entry if it exists. Affected file silcd/packet_receive.c,
259 * Send the channel message always to only one router, either
260 in upstream or downstream. Affected file is
263 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
265 * Wrote the definition of the backup resuming protocol to the
266 protocol specification.
268 * Removed one redundant channel key generation from normal
269 server during joining procedure. Removed one redundant
270 channel key sending from server to router during joining
271 procedure. Affected file silcd/command.c.
273 * Made minor bugfixes to the backup router resuming protocol.
274 Affected file silcd/server_backup.c, server.c.
276 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
278 * Added --disable-asm configuration option. Affected files
279 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
282 * Implemented the backup resuming protocol that is used to
283 resume the primary router position in the cell after the
284 primary router comes back online. Affected files
285 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
286 and silcd/server_util.[ch].

294 send any data. Affected file silcd/packet_send.c.
296 * Assure that if outgoing data buffer is pending do not force
297 send any data. Affected file lib/silcclient/client.c.
299 * Implemented the backup router support when the primary router
300 goes down. The servers and routers can now use the backup
301 router as new primary router without loosing connectivity.
303 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
306 in the server to indicate disabled entry. All data read
307 from the connection will be ignored and no data is sent
308 for entry that is disabled. Affected files are
309 silcd/idlist.h, silcd/server.c.
311 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
313 * Created SFTP client and server test programs in the
314 lib/silcsftp/tests directory.
316 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Implemented memory filesystem (virtual filesystem) for
319 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
322 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Implemented the SFTP (SSH File Transfer Protocol) to the
325 lib/silcsftp. It includes SFTP client and SFTP server
328 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Moved lib/silccore/silcprotocol.[ch] to the
331 lib/silcutil library.
333 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
334 take variable argument list pointer as argument. Affected
335 file lib/silcutil/silcbuffmt.[ch].
337 * Added silc_buffer_set function that is used to set data
338 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
339 Affected file lib/silcutil/silcbuffer.h.
341 * Changed various routines in the core library to use the new
342 silc_buffer_set instead of allocating new buffer only for
345 * Added 64-bit value formatting and unformatting support to the
346 silc_buffer_[un]format routines. Affected file is
347 lib/silcutil/silcbuffmt.[ch].
349 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
350 to includes/bitmove.h.
352 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
354 * Fixed channel user mode saving in client library. Affected
355 file lib/silcclient/command[_reply].c.
357 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
359 * Defined the file transfer to the SILC Protocol. Added
360 new packet type SILC_PACKET_FTP and defined File Transfer
361 Payload. The mandatory file transfer protocol is SFTP
362 (SSH File Transfer Protocol). Affected file in addition
363 of the internet draft is lib/silccore/silcpacket.h.
365 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
366 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
367 is used as part of backup router protocol when the primary
368 router of the cell is back online and wishes to resume
369 the position as primary router.
371 * Redefined the MAC generation keys in the protocol. The
372 same key is not used anymore in both direction. Both
373 direction will now use different keys for sending and
374 receiving. This fixes a potential security flaw. This
375 change causes incompatibilities in the protocol.
377 * Redefined also the MAC computation from the packet.
378 An packet sequence number is now added to the MAC
379 computation. This prevents possible replay attacks against
380 the protocol. This change too causes incompatibilities
383 Added `sequence' field to the SilcPacketContext to hold
384 the current sequence number for the packet.
386 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Added `created' field to the SilcIDListData in the file
389 silcd/idlist.h to indicate the time when the entry was
392 * Added `created' field to the SilcChannelEntry too. Affected
395 * Added `creation_time' aguments to all the announcement functions
396 in the server. If it is provided then only the entries that
397 was created after the provided time frame are actually
398 announced. Affected file silcd/server.[ch].
400 * The protocol says that the Channel ID's IP address must be
401 based on the router's IP address. Added check for this in
402 the silc_server_new_channel when processing incoming New Channel
403 Payload. Affected file silcd/packet_receive.c.
405 * Print out the correct version with --version in SILC client.
406 Affected file irssi/src/silc/core/silc-core.c.
408 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

411 entry always, not just when the command is coming from client.
412 Affected file silcd/command.c.
414 * Added new function silc_server_packet_queue_purge to purge the
415 outgoing data queue to the network. After the function returns
416 it is guaranteed that the outgoing packet queue is empty.
417 Affected file silcd/packet_send.[ch].
419 * Purge the outgoing packet queue in the rekey protocol's final
420 callback to assure that all rekey packets go to the network
421 before quitting the protocol. Affected file silcd/server.c.
423 * Added silc_client_packet_queue_parse as similar function as
424 in server to the client library. The affected file is
425 lib/silcclient/client.c.
427 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Splitted silcd/server.c and created silcd/server_util.[ch]
430 for utility functions.
432 * Added new socket flag SILC_SF_DISABLED to indicate that the
433 connection is open but nothing can be sent to or received from
434 the connection. Affected file lib/silcutil/silsockconn.[ch].
435 The checking for disabled socket is checked in the low level
436 silc_socket_write and silc_socket_read functions.
438 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Allow only nicknames and channel names that fits into the
441 7-bit unsigned char ASCII set. Affected file silcd/command.c.
443 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
445 * When processing JOIN command reply in server check that if
446 the channel exists in our global list we'll move it the local
447 list. Affected file silcd/command_reply.c.
449 * Fixed the check whether client is joined on the channel already
450 in JOIN command. Affected file lib/silcclient/command.c.
452 * Fixed the JOIN command reply to check whether the channel
453 already exists. Affected file lib/silcclient/command_reply.c.
455 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
457 * Added silc_ske_status_string to map the SKE error numbers
458 to readable strings. The affected files are
459 lib/silcske/silcske[_status].[ch].
461 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Do not show the private channels on the WHOIS channel list
464 as it is not allowed by the protocol. The affected file is
467 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
469 * Assure that the packet length digged from the actual packet
470 is something sensible in the silc_packet_decrypt_rest_special
471 in lib/silccrypt/silcpacket.c.
473 * Free and NULL the allocated pointer in silc_hmac_alloc if
474 the HMAC allocation fails. The affected file is
475 lib/silccrypt/silchmac.c.
477 * Print the selected security properties to the log files in
478 the server. Affected file silcd/protocol.c.
480 * Add SKE's reference counter even if calling the completion
481 callback manually. Otherwise it goes negative, although it
482 does not cause any problems. The affected file is
483 lib/silcske/silcske.c.
485 * Remove the client entry with short timeout after giving the
486 KILL command. Affected file lib/silcclient/command.c.
488 * Fixed to send error reply in WHOIS and IDENTIFY commands in
489 case all found clients are already disconnected (WHOWAS would
490 found them) in the server. Affected file silcd/command.c.
492 * Update the last_receive (time of last data received) to be
493 updated only when received private or channel message so that
494 the idle time showed in WHOIS makes more sense.
496 * Added boolean field `valid' in to the SilcClientEntry in the
497 client library to indicate whether the entry is valid or not.
498 This fixes the nickname change bug on channel when changing
499 the nickname to be same than the old (like nick to Nick) the
500 nickname formatter doesn't set the new nick anymore to Nick@host.
501 Affected file lib/silcclient/idlist.[ch].
503 * Now actually fixed the nickname changing on disconnection.
504 Added new function silc_change_nick to the Irssi SILC Client.
505 Affected file irssi/src/silc/core/client_ops.c,
506 irssi/src/silc/core/silc-nicklist.[ch].
508 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Check that the public key exists in the GETKEY command before
511 trying to encode it. Affected file silcd/command.c.
513 * Print some notifications on received public keys with GETKEY
514 command in the Irssi SILC Client. Affected files are
515 irssi/src/fe-common/silc/module-formats.[ch],
516 irssi/src/silc/core/client_ops.c.
518 * Use IDENTIFY command to resolve the server information in the
519 GETKEY command instead of INFO command. Affected file
520 lib/silcclient/command.c.
522 * All command reply functions in the client library now calls
523 the pending command reply callbacks even if an error has
524 occurred. The server has done this a long time and now it was
525 time to move the client library to this as well. Now all
526 errors can be delivered back to the pending command reply
527 callbacks if necessary. Affected files are
528 lib/silcclient/command[_reply].[ch].
530 * Change the nickname on disconnection back to the username
531 because in reconnect the server will enforce it to it anyway.
532 Affected file irssi/src/silc/core/silc-servers.c.
534 * Fixed a config file parsing bug in the Irssi SILC client.
535 Affected file irssi/src/silc/core/clientconfig.c.
537 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
539 * When printing the channel mode on JOIN, verify that the
540 channel key and channel's HMAC are valid. Affected file
541 irssi/src/silc/core/client_ops.c.
543 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
545 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
546 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
547 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
549 * Removed channel key rekey task deleting from the function
550 silc_server_save_channel_key. Affected file silcd/server.c.
551 Added explicit timeout task context instead that is used to
552 delete the task if we are registering a new task before the
553 new task has elapsed.
555 * When channel key rekey occurs the client library now saves
556 the old channel key for a short period of time (10 seconds) and
557 is able to use it in case some is still sending channel
558 messages encrypted with the old key after the rekey. Affected
559 file lib/silcclient/[idlist.h|client_channel.c].
561 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
563 * Added check to the silc_server_new_id_real to not accept
564 new ID if it is the sender's own ID. Affected file is
565 silcd/packet_receive.c.
567 * Assure that we do not announce ourself or the one we've
568 sending our announcements when we're router and are announcing
569 servers to our primary router. Affected file silcd/server.c.
571 * Fixed silc_server_command_identify_check_client to assemble
572 correct WHOIS packet. It send corrupted WHOIS packet and
573 caused problem with router to router connections. Affected
574 file silcd/command.c.
576 Fixed also silc_server_command_whois_check the same way
577 as for the IDENTIFY command.
579 * Added new SilcIDListStatus to the server in the SilcIDListData
580 structure. The status now includes the current status of
581 the entry (like registered, resolved etc.). Affected file
582 silcd/idlist.[ch]. Defined a bunch of different status types
583 as well. This replaced the old boolean registered field as well.
585 Added resolve_cmd_ident field to the SilcClientEntry structure
586 too so that if the entry is for example being resolved so
587 another command may attach to the same pending command reply
588 without requiring to resolve the same entry again. This concept
589 should optimize the WHOIS and the IDENTIFY resolving under
590 heavy load by taking away unnecessary resolving for entries
591 that are being resolved already.
593 Added support for adding multiple pending commands for one
594 command idenfier. Affected file silcd/command[_reply].[ch].
596 * Fixed WHOIS and IDENTIFY save to remove the cache entry
597 before deleting the data. Otherwise the hash table will have
598 freed data in comparison functions. Affected file is
599 silcd/command_reply.c.
601 * Fixed silc_idlist_replace_client_id to add the new entry to
602 the cache with NULL nickname. Otherwise there will be invalid
603 memory as the nickname after the nickname is freed. Affected
604 file silcd/packet_receive.c.
606 * Fixed the silc_idlist_get_clients_by_hash. The entries was
607 saved into wrong slots because the previous number of entries
608 was not taken into account. Affected file silcd/idlist.c.
609 Fixed same thing in silc_idlist_get_clients_by_nickname too.
611 * If we are router and we receive JOIN notify to a channel that
612 does not have any users then notified client is marked as the
613 channel founder, as it is it. The affected file is
614 silcd/packet_receive.c
616 * Added to the extended hash table API's table_del_*ext functions
617 the destructor as argument too, so that the caller can decide
618 which destructor to use or whether to use destructor at all.
619 Affected file lib/silcutil/silchashtable.[ch].
621 * Fixed ID Cache purging. It actually deleted the entries from
622 the hash table after the data was freed. The hash table ended
623 up comparing freed memory. The affected file is
624 lib/silccore/silcidcache.c.
626 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
628 * Fixed Irssi SILC client's KILL command's HELP syntax.
630 * The USERS command now resolves the detailed user information
631 if the userinfo field is missing. Affected file is
632 lib/silcclient/command_reply.c.
634 * Do not print error in silc_file_read if the read file does
635 not exist. Just silently return NULL. Affected file is
636 lib/silcutil/silcutil.c.
638 * Fixed the silc_log_output to not wine about NULL filename
639 and to not create some bogus " " filename. Affected file is
640 lib/silcutil/silclog.c.
642 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Fixed various printing bugs on the user interface in the
645 Irssi SILC Client. Minor changes that were forgotten from
648 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Fixed the configure.in.pre and the compilation and distribution
651 environment to support the new autoconf 2.52. That version is
652 now required to compile the CVS trunk.
654 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Renamed function silc_parse_nickname to silc_parse_userfqdn
657 to generally parse user@fqdn format strings. Affected file
658 lib/silcutil/silcutil.c.
660 * Added nickname_format and nickname_force_format fields to the
661 SilcClientParams structure. The first one defines the format
662 for the nicknames that the library will enforce if the receives
663 multiple same nicknames. The second one is boolean value and
664 can be used to force the library to always enforce the format
665 to the nicknames regardles whether there are multiple nicknames
666 or not. This configurable formatting was employed to flexibly
667 support accessing multiple nicknames from the user interface.
668 The userinterface can now set the nicknames to what ever format
669 they prefer. Affected file lib/silcclient/silcapi.h.
671 Added function silc_client_nickname_format to the file
672 lib/silcclient/idlist.c. It performs the nickname formatting.
674 Added new field `hostname´ to the SilcClientEntry context.
675 It holds the hostname of the client. Affected file is
676 lib/silcclient/idlist.h.
678 * Irssi SILC Client sets the nicknames in nick@hostn format.
679 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
680 irssi/src/silc/core/silc-core.c.
682 The WHOIS printing now also shows both the real nickname and
683 the formatted nickname so that user knows how to access the
684 user if there are multiple same nicknames cached. Affected
685 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
686 printing formatting too to take the hostname now as a separate
687 argument. The Affected file is
688 irssi/src/fe-common/silc/modules-formats.[ch].
690 * Changed the silc_client_get_clients_local to accept the formatted
691 nickname as argument. It accepts the real nickname too but the
692 formatted nickname can be used to find the true entry from
693 multiple entries. Affected file lib/silcclient/silcapi.h and
694 lib/silcclient/idlist.c.
696 * Added nickname_format_parse field to the SilcClientParams.
697 It is a callback function provided by the application to parse
698 the nickname out of the formatted nickname string. The library
699 calls it to get the nickname from the formatted string. Since
700 the application generally knows better the format of the nickname
701 string it parses it instead of the library, even though library
702 encodes the formatted string. If the callback function is not
703 provided then the library will use the string as is. The
704 affected file is lib/silcclient/silcapi.h.
706 * All the nickname strings passed to the client library in
707 commands are now expected to be formatted nickname strings.
708 If the command does not support the formatted nickname string
709 it will assume that the sent string is the actual nickname.
710 Affected file lib/silcclient/command.c.
712 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
714 * Added public key authentication support to OPER and SILCOPER
715 commands in the client library. Affected file is
716 lib/silcclient/command.c.
718 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Changed the get_auth_methdod client operation to be asynchronous.
721 It can be async if the application resolves the authentication
722 method from the server during the negotiation. Added new
723 SilcGetAuthMeth completion callback that the application will
724 call after resolving the authentication method.
726 Added function silc_client_request_authentication_method that
727 the application can use to resolve the authentication method
728 from the server. Added also SilcConnectionAuthRequest callback
729 that the library will call after the server has replied. The
730 application can call this function if it does not know the
731 current authentication method.
733 Affected files are lib/silcclient/client.c and
734 lib/silcclient/silcapi.h.
736 * The Irssi SILC client now automatically resolves the authentication
737 method incase any configuration information is not present (and
738 currently there never is). The affected file is
739 irssi/src/silc/core/client_ops.c.
741 * Fixed public key authentication from the client library.
742 Affected file lib/silcclient/protocol.c. Changed also the
743 protocol specification about the public key authentication in
744 the connection authentication protocol. The actual data to be
745 signed is now computed with a hash function before signing.
747 * Fixed the public key authentication from the server as well.
748 Affected file silcd/protocol.c.
750 * Removed the mlock()'s from the memory allocation routines.
751 Affected file lib/silcutil/silcmemory.c. The ./configure does
752 not check anymore for the mlock(). Affected file is
755 * Fixed USERS command in server to allow the execution of the
756 command for private and secret channels if the client sending
757 the command is on the channel. Affected file silcd/command.c.
759 * Fixed silc_client_get_clients_local to return the clients
760 count correctly. It could return wrong value. Affected file
761 lib/silcclient/idlist.c.
763 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
766 types. The assembler optimizations seemed not to like 64-bit
767 data types. The assmebler optimizations thus are now enabled
768 also for BSD systems as opposed to only enable them for Linux.
770 * Do not check for threads at all on BSD systems. Affected
771 file configure.in.pre.
773 * Removed -n and -h options from the Irssi SILC Client since
774 they are not used in silc.
776 * Fixed the prime generation to assure that the first digit
777 of the generated random number is not zero since our conversion
778 routines does not like number strings that starts with zero
779 digit. If zero digit is seen the random number is regenerated.
780 This caused some corrupted RSA keys when the zero first digit
781 was met. Affected file lib/silcmath/silcprimegen.c.
783 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
785 * Fixed WIN32 configuration in the ./configure script.
786 Fixed to include xti.h on environments that has it.
787 Patches by Carsten Ilchmann and andrew.
789 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
791 * Changed the silc_id_create_client_id to be collision
792 resistant. It is now assured that there cannot be created
793 two same client ID's. I suspect that some weird bugs in
794 the server were actually caused by duplicate Client IDs.
795 Affected file silcd/serverid.[ch]. A router receiving
796 new ID now also assures and informs the sending server
797 if the ID caused collision.
799 * Changed the silc_id_create_channel_id to also assure that
800 there are no collisions.
802 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
804 * Statement about ignoring the Mutual Authentication flag when
805 performing rekey with PFS was a bit misleading. It is ignored
806 if it was set in the initial negotiation, it cannot be even
807 set in the rekey. Fixed in the ke-auth draft. Started the
808 new versions of the protocol drafts in the doc/.
810 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Fixed a bug in silc_client_command_identify_save when saving
813 new channel information. The channel name was no duplicated
814 and caused crash on exit. Affected file is
815 lib/silcclient/command_reply.c.
817 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Fixed the getkey command handling in the server. Send just
820 empty OK reply to the sender if the key could not be fetched
821 (but everything else was ok, like the key just was not available).
822 Changed the public key parameter to optional in the protocol
823 specs so that empty OK reply can be sent. Affected file
826 Added a message to Irssi SILC client to tell to user if the
827 server did not return a public key.
829 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed a channel key regeneration bug. It registered new
832 timeout tasks exponentially until all system resources were
833 used. Affected file silcd/server.c.
835 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Added the SILC Document generator to the scripts/silcdoc.
838 It can be used to generate the Toolkit Reference Manual out
839 of the source tree. Internally it will also use the RoboDoc
840 generator now imported in util/robodoc.
842 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
844 * Added couple of return's in rekey protocol if error orccurred
845 during the protocol. The execution must be terminated.
846 Affected file silcd/protocol.c. Also, terminate the protocol
849 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
851 * The client's Client ID was created initally from the wrong
852 nickname (it could have been in format nick@host) in the
853 silc_server_new_client. Affected file silcd/packet_receive.c
855 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Added some SILC_LOG_ERROR's to various error conditions
858 if client could not be added to ID cache. Affected files
859 silcd/packet_receive.c and silcd/server.c.
861 * When client's sock->user_data is freed, NULL also the
862 client->router and client->connection pointers. Added check
863 for these pointers being NULL to various places around the
864 code. Affected file silcd/server.c.
866 * Added client->data.registered == TRUE checks to various
867 places around the code to assure that unregistered client's
868 are not handled when it is not allowed. Affected file
871 * Added `bool registered' fields to all
872 silc_idlist_[server|client]_get_* routines to indicate whether
873 the fetched client needs to be registered or not. Affected
874 file silcd/idlist.[ch].
876 * Add your own entry as registered to the ID cache in the
877 server. Affected file server.c.
879 * Fixed a bug in silc_server_new_server. The SilcServer was
880 set as the new server's context instead of SilcServerEntry.
881 This naturally caused some weird bugs.
883 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Do not delete the channel rekey task when adding it
886 for in silc_server_create_channel_key.
888 * Changed the silc_server_create_channel_key to return
889 TRUE or FALSE to indicate the success of the channel key
892 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Fixed MSVC++ project files and added missing files to
895 Makefiles under win32/.
897 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
899 * Do not add TCP_NODELAY flag if the operating system
900 does not have it defined. Affected files are
901 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
903 * Fixed buffer overflow from Irssi SILC Client. Affected
904 file irssi/src/fe-common/core/themes.c.
906 * Fixed double free in client library in the file
907 lib/silcclient/client.c when disconnecting from server.
909 * Applied double free patch from cras to Irssi SILC client.
910 Affected files irssi/src/core/[modules/expandos].c
912 * Fixed the disconnection handling to Irssi SILC Client.
913 The application must call silc_client_close_connection
914 in ops->connect client operation in case of failure of
915 the connection. Affected file is
916 irssi/src/silc/core/client_ops.c.
918 * Do not set sock->protocol to NULL in the function
919 silc_client_close_connection after executing the protocol's
920 final callback since the sock might not be valid anymore.
921 Affected file lib/silcclient/client.c.
923 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
925 * Do not enable SILC_THREADS if the linking with libpthread
926 did not happen. Affected file configure.in.pre.
928 * Added notion to protocol specification that server must
929 verify the sent authentication payload with CMODE when
930 setting the channel founder key. Implemented it to the
931 server. Affected file silcd/command.c.
933 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Added _EXTRA_DIST SILC distribution variable to the
936 distributions file. It is used to conditionally add extra
937 files or directories to the specific distribution. Affected
938 files ./prepare, Makefile.am.pre and distributions.
940 Removed the `_' from the start of the distribution names.
943 * Added README.WIN32 for instructions to compile the Toolkit
946 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
948 * Fixed a double free in disconnection in the server. Affected
949 file is silcd/server.c.
951 * Fixed the lib/silcske/groups.c to work now also with GMP
952 MP library. The string conversion did not work when using
953 specific base and the base is indicated in the string as well.
955 * Created win32/ directory which now includes MSVC++ specific
956 stuff so that toolkit (DLLs) may be compiled with MSVC++.
957 It will appear only in the toolkit distribution
959 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Changed the key material distribution function in case when
962 the hash output is too short. The data is now concatenated
963 a bit differently than it used to. Made the change to the
964 SKE protocol specification.
966 * Added better GMP detection to configure.in.pre. A patch
969 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Fixed a minor bug in SKE that might cause some problem on
972 some platforms. Affected file lib/silcske/silcske.c.
974 * Added the cookie checking for initiator in the SKE. It checks
975 that the responder returns the sent cookie unmodified. The
976 affected file is lib/silcske/silcske.c. Added new SKE
977 error type INVALID_COOKIE that can be sent during the
978 negotiation. Fixed some memory leaks as well.
980 * Added the "invalid cookie" error message to Irssi SILC client's
983 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
985 * Added `task_max' field to the SilcClientParams to indicate
986 the maximum tasks the scheduler can handle. If set to zero,
987 default values are used. Affected file lib/silcclient/silcapi.h.
989 * Fixed memory leaks in silc_client_close_connection. Affected
990 file lib/silcclient/client.c.
992 * Added silc_client_del_client_entry to client library to free
993 all memory of given client entry. Affected file is
994 lib/silcclient/idlist.[ch].
996 * Added new functions silc_client_del_channel and
997 silc_client_del_server to delete channel and server entries.
998 Affected file lib/silcclient/[silcapi.h/idlist.c].
1000 * Removed silc_client_del_client_by_id from silcapi.h.
1002 * Fixed the INFO command to return the server's own info
1003 correctly when querying by Server ID. Affected file is
1006 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Removed the non-blocking settings in WIN32 code in the
1009 silc_sock_[read/write] and added SleepEx instead. Affected
1010 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1011 of input data is now checked with FIONREAD and ioctlsocket.
1013 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Call silc_schedule_task_del_by_context in the
1016 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1017 Affected file lib/silccore/silcprotocol.c.
1019 * Call silc_protocol_cancel for active protocols in the
1020 silc_server_close_connection if the funtion
1021 silc_server_free_sock_user_data has not been called.
1022 Affected file silcd/server.c.
1024 * Generic tasks cannot be deleted using the del_by_fd
1025 task deleting function since generic tasks does not match
1026 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1028 * Added a notion to SILCOPER help file that the SILCOPER works
1029 only on router server, not on normal server.
1031 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * Added for WIN32 support for the new scheduler as well.
1034 Affected file lib/silcutil/win32/silcwin32schedule.c.
1036 * Fixed the SHA1 implementation to work on various platforms.
1038 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1041 API. It is part of the scheduler now. Everything else is
1042 as previously but some functions has changed their names.
1043 Checkout the lib/silcutil/silcschedule.h for the interface.
1044 Updated all applications to use the new interface. Affected
1045 files are lib/silcutil/silcschedule.[ch].
1047 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1049 * Found a bug in the SKE implementation. The HASH value,
1050 specified by the protocol, was not computed correctly. The
1051 public key of the responder was not added to the computation
1052 even though it is mandatory. Affected file lib/silcske/silcske.c.
1053 This unfortunately causes incompatibilities with older
1054 clients and servers.
1056 * Added WIN32 specific network init and uninit functions:
1057 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1058 the Winsock2. Affected file lib/silcutil/silcnet.h and
1059 lib/silcutil/win32/silcwin32net.c.
1061 * Set the socket always to nonblocking mode on WIN32 after
1062 reading data or writing data. Affected file is
1063 lib/silcutil/win32/silcwin32sockconn.c.
1065 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1067 * Fixed various compilation problems under WIN32. Affected
1068 files lib/silcutil/win32/silcwin32thread.c and
1069 lib/silcutil/win32/silcwin32schedule.c.
1071 * Removed all _internal.h #includes from public header
1072 files. Internal headers must never be included from
1075 Removed also the lib/silcske/payload_internal.h file.
1077 * All include files that may be needed (public and some others
1078 included by the public headers) by application developers are
1079 now copied to the ./includes directory. It does not copy any
1080 internal headers. Affected file Makefile.defines.pre and all
1081 Makefile.am's under lib/ and subdirs.
1083 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Do not change the ~/.silc directory's permissions automatically.
1086 Affected file irssi/src/silc/core/clientutil.c.
1088 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1090 * Do not cancel the protocol in silc_server_close_connection
1091 it might cause recursion. Now cancelled in the function
1092 silc_server_free_sock_user_data. Affected file silcd/server.c.
1094 * Fixed the silc_server_remove_clients_by_server to regenerate
1095 the channel keys correctly finally. Added also new function
1096 silc_server_remove_clients_channels to actually do it.
1097 Affected file silcd/server.c.
1099 * Fixed the silc_server_new_channel to not crash by giving
1100 wrong router to the new channel. Affected file is
1101 silcd/packet_receive.c.
1103 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1106 which is given as argument to the silc_client_alloc now.
1107 It can be used to configure the client and set various parameters
1108 that affect the function of the client.
1110 * The USERS command in server did not check whether the channel
1111 is private or secret. Affected file silcd/command.c.
1113 * Added new argument to the USERS command in protocol specification.
1114 The USERS command now can take the channel name as argument
1115 as well. Added support for this in client and server and
1116 updated the protocol specs.
1118 * Completed the GETKEY command in client. It can be now used
1119 to fetch also servers public key not only some clients.
1120 Affected files lib/silcclient/command[_reply].c.
1122 * Added silc_client_get_server to return server entry by the
1123 server name. Affected files lib/silcclient/silcapi.h and
1126 * Redefined the IDENTIFY command in protocol specification to be
1127 more generic. It now can be used to query information about
1128 any entity in the SILC Network, including clients, servers and
1129 channels. The query may be based either the entity's name
1130 or the ID. Added support for this in both client and server.
1132 Affected files silcd/command.c and lib/silcclient/command.c
1133 and command_reply.c.
1135 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1136 the _from_client and _from_server functions. Affected file
1139 * Added silc_client_get_channel_by_id_resolve to the file
1140 lib/silcclient/silcapi.h to resolve channel information by
1141 its ID. Added also silc_client_get_channel_by_id that
1142 does not resolve it from the server.
1144 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1146 * Added SilcServerEntry context into the client library
1147 to represent one server. The INFO command now allocates
1148 these to save the resolved server info. For now on the
1149 client library will also keep information about servers,
1150 connected and resolved with INFO.
1152 The INFO command now allocates the SilcServerEntry context
1153 and saves the server info there. The COMMAND_REPLY in
1154 the INFO now returns the parameters to application in
1155 same order as defined in the protocol specification.
1157 The entries are cached in the client->server_cache.
1159 * The INFO command is now issued after received the Client ID
1160 from the server. Affected file lib/silcclient/client.c.
1162 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1163 to the application as the mode changer might be server.
1164 It is guaranteed that NULL is not returned anymore to the
1165 application. Affected file lib/silcclient/client_notify.c.
1167 The ID Type is now also passed to the application so that
1168 it can check whether the returned entry is SilcClientEntry
1171 Added new function silc_client_get_server_by_id to return
1172 the server entry by ID. Affected files are the
1173 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1175 * Do not create the channel in the Irssi SILC Client when issuing
1176 the JOIN command but when received the sucessful JOIN command
1177 reply. Otherwise the channel might get created even though we
1178 could not join it. The Affected file is
1179 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1181 * Fixed a channel joining bug in router. The router must also
1182 check the channel modes, invite and ban lists etc. when serving
1183 the JOIN command sent by normal server. Affected file is
1184 silcd/command.c. The router now resolves the client's
1185 information from the server who sent the JOIN command if it
1186 does not know it, and processes the JOIN command only after
1189 * Changed the SilcCommandCb to take new argument; void *context2.
1190 Affected file lib/silccore/silccommand.h
1192 The second argument in the command callbacks in the server now
1193 includes the SilcServerCommandReplyContext if the command was
1194 called as pending command callback from the command reply.
1195 Otherwise it is NULL. When called as pending the status of the
1196 command reply will be checked and if it was erronous the
1197 error will be sent to the original sender of the command.
1198 This way the client always receives the error messages even
1199 though the server was actually the one who received the error
1200 when it resent the command to router, for example. Affected
1201 files silcd/command[_reply].[ch].
1203 * Fixed sending WHOWAS command's error message to client if
1204 the requested client could not be found. It was missing.
1207 * Changed the CMODE and CUMODE commands reply arguments in the
1208 protocol specification. The Channel ID is now sent in both
1209 of the commands to identify the channel. Implemented this
1210 new feature to the client and server. Affected files
1211 lib/silcclient/command_reply.c and silcd/command.c.
1213 * Made better checks for invite and ban lists in the JOIN
1214 command in server. Affected file silcd/command.c.
1216 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * The server now performs the incoming host IP/DNS lookup
1219 using the silc_socket_host_lookup and thus does not block
1220 the server anymore. Affected file silcd/server.c.
1222 * Completed the multi-thread support for SILC Scheduler in
1223 the lib/silcutil/silcschedule.c.
1225 * Fixed the configure.in.pre to detect the pthread correctly
1228 * Fixed a deadlock in silc_task_queue_wakeup in the file
1229 lib/silcutil/silctask.c.
1231 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Added new function silc_schedule_wakeup that is used in
1234 multi-threaded environment to wakeup the main thread's
1235 schduler. It needs to be used when a thread adds a new task
1236 or removes a task from task queues. After waking up, the
1237 scheduler will detect the task queue changes. If threads
1238 support is not compiled in this function has no effect.
1239 Implemented the wakeup mechanism to both Unix and WIN32
1240 systems. Affected files are lib/silcutil/silcschedule.[ch],
1241 lib/silcutil/unix/silcunixschedule.c and the
1242 lib/silcutil/win32/silcwin32schedule.c.
1244 * Added new function silc_task_queue_wakeup to wakeup the
1245 scheduler by the specified task queue. Affected file
1246 lib/silcutil/silctask.[ch].
1248 * The silc_socket_host_lookup_start now wakes up the scheduler
1249 after adding the timeout task. Affected file is
1250 lib/silcutil/silcsockconn.c.
1252 * The silc_socket_host_lookup is synchronous now if the threads
1253 support is not compiled in. However, the callback is still
1254 called asyncronously through the scheduler, anyway. Affected
1255 file lib/silcutil/silcsockconn.c.
1257 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Added new function silc_socket_host_lookup to perform
1260 asynchronous IP and FQDN lookups for the socket connection.
1261 Affected files lib/silcutil/silcsockconn.[ch].
1263 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1266 that may or may not compile the mutex support in.
1268 Changed the silc_mutex_alloc interface. It allocates the
1269 mutex now to the sent pointer and returns TRUE or FALSE.
1271 Affected file lib/silcutil/silcmutex.h.
1273 * Wrote the SILC Task Queue interface to support multi-threads.
1274 Affected file lib/silcutil/silctask.[ch].
1276 * Wrote the SILC Scheduler to support multi-threads. Affected
1277 file lib/silcutil/silcschedule.c.
1279 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1282 in lib/silcutil/win32/.
1284 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Defined SILC Mutex API and SILC Thread API and implemented
1287 them for Unix. Affected files are
1288 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1289 lib/silcutil/unix/silcunixmutex.c and
1290 lib/silcutil/unix/silcunixthread.c.
1292 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Fixed the silc_server_remove_clients_by_server's channel
1295 key re-generation. The hash table handling was incorrect
1296 and would not work with many channels. Affected file is
1299 * Fixed some memory leaks around the server code.
1301 * Rewrote the silc_server_get_users_on_channel to support IPv6
1302 based Client ID's. Affected file silcd/server.c.
1304 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1305 specification. However, a separate document must be written
1306 to define the detailed signing procedure and the payload
1307 associated with the flag. Defined the flag to the
1308 lib/silccore/silcchannel.h as well.
1310 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Changed the dynamic tables to static size tables in the
1313 lib/silccrypt/silchmac.c.
1315 * Removed GCC dependencies from the code. A patch by cras.
1317 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Do not show the error "Error receiving packet bla bla"
1320 in server if it really was not an error (-2 means that reading
1321 is pending). Affected file silcd/server.c.
1323 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Fixed a possible crash in silc_server_remove_clients_by_server
1326 in silcd/server.c. Fixed there also some memory leaks.
1328 * Fixed the silc_idlist_replace_client_id. It could replace
1329 wrong key in the hash table. Affected file silcd/idlist.c.
1331 * Do not check whether there are global users on the channel
1332 if the channel->global_users is FALSE. Affected functions
1333 silc_server_remove_from_one_channel and
1334 silc_server_remove_from_channels in silcd/server.c. Also,
1335 do not check if the removed client is local as we can be
1336 sure that global client was not removed from the channel
1337 and checking for global users is not needed.
1339 * The silc_server_remove_clients_by_server now re-generates
1340 the channel keys correctly for those channels that had
1341 clients removed from them. Affected file silcd/server.c.
1343 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Found the reason of random crashes in the server. We weren't
1346 ignoring the SIGPIPE signal (which can be sent in write())
1347 and it crashed the server. Affected file silcd/silcd.c.
1349 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Assure that sock->user_data is not NULL in the function
1352 silc_server_packet_send in silcd/packet_send.c.
1354 * Disconnect the remote connection if it could not be added
1355 to any ID lists in the server. The affected file is
1358 * Check in silc_server_packet_send[_real/dest] that the
1359 socket is not disconnecting and ignore the data if it is.
1360 Affected file silcd/packet_send.c.
1362 * Define inline to __inline on native WIN32 compilation.
1363 Affected file includes/silcwin32.h.
1365 * Added some explicit type casts for inline code since MSVC
1366 require them. Affected files lib/silcutil/silcbuffer.h,
1367 lib/trq/silcdlist.h and lib/trq/silclist.h.
1369 * Print warning in log files from now on if the packet
1370 decryption fails. Affected file silcd/server.c.
1372 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Changed the `say' client operation's interface to accept
1375 new `type' argument to indicate the type of the message sent
1376 by the library. The application may filter the library's
1377 messages according the type. The affected file is the
1378 lib/silcclient/silcapi.h.
1380 * Added two new functions to lib/silcclient/silcapi.h:
1381 silc_client_del_client and silc_client_del_client_by_id.
1382 Affected file lib/silcclient/idlist.c.
1384 * Moved the clientincludes.h from includes/ to silc/ and
1385 serverincludes.h from includes/ to silcd/.
1387 * The modes for the CMODE and CUMODE are now passed as
1388 uint32 for application with COMMAND_REPLY. The affected
1389 file is lib/silcclient/command_reply.c.
1391 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * /WHOIS without arguments shows client's own information.
1394 Affected file lib/silcclient/command.c.
1396 * Changed PING to not accept any arguments. The specs
1397 says that client can ping only the connected server so
1398 requiring an argument is not needed. Affected file is
1399 lib/silcclient/command.c.
1401 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Fixed a fatal bug in private message sending and reception
1404 encryption and decryption when using private message keys.
1405 The implementation was incorrect and did not follow the
1406 specification. It causd that some of the message were
1407 lost since it did not use the sending and receiving keys
1408 as the protocol suggests. This has been fixed and will cause
1409 incompatibilities with older clients when sending private
1410 message encrypted with private message keys. Affected files
1411 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1412 and various other in Irssi SILC Client.
1414 Added `responder' boolean argument to the functions
1415 silc_client_add_private_message_key[_ske] to indicate when
1416 the key is added as responder or initiator of the key
1419 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Removed the silc_ske_check_version function and created
1422 a SilcSKECheckVersion callback. Added also a function
1423 silc_ske_set_callbacks that is now used to set all SKE
1424 callbacks. The callback functions are not given to
1425 the SKE functions anymore, but this function is used to
1428 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1430 * Added `silc_version' argument to the silc_client_alloc
1431 to define the version of the application for the library.
1432 The library will use the version string to compare it
1433 against the remote host's (usually a server) version
1434 string. Affected file lib/silcclient/silcapi.h
1436 * Added the KE protocol context to Key Agreement context
1437 in client library so that we can abort the SKE if it
1438 is in process when we get timeout. Affected file is
1439 lib/silcclient/client_keyagr.c.
1441 * Do not resolve the client ID forever if it returns in the
1442 first time that such client does not exist. This was done
1443 for example with private message. Affected file is
1444 lib/silcclient/client_prvmsg.c.
1446 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Do not add regex.h for WIN32. The affected file
1449 includes/silcincludes.h.
1451 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1452 not work yet 100%. It generates the DLL's automatically
1453 when compiling with --with-win32 under cygwin.
1455 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * lib/contrib/regex.c is not compiled on WIN32.
1459 * Added silc_net_get_socket_opt function to the
1460 lib/silcutil/silcnet.h.
1462 * Added includes/silcwin32.h for WIN32 specific includes
1465 * Do not use ptime structure or any of the posix process
1466 functions on WIN32 in lib/silccrypt/silrng.c.
1468 * Added silc_gettimeofday to provide generic function
1469 for struct timeval on all platforms. Added the function
1470 to lib/silcutil/silcutil.h.
1472 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1475 library as they clearly belong there. As a plus side we
1476 can make the actual socket connection routines platform
1479 Added also new generic function silc_socket_read and
1480 silc_socket_write (that used to be silc_packet_[read/write].
1481 The implementation of these are platform specific.
1483 * Added WIN32 specific routines of silc_socket_[read/write]
1484 to lib/silcutil/win32/silcwin32sockconn.c.
1486 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Added preliminary support for native WIN32 compilation under
1489 cygwin (using the -mno-cygwin option for GCC) to the
1490 ./configure.in.pre. The --with-win32 now prepares the
1491 compilation for native WIN32.
1493 * Rewrote the SILC Scheduler interface in the file
1494 lib/silcutil/silcschedule.h. The scheduler is now context
1495 based and does not have anymore any global static scheduler.
1496 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1497 and created lib/silcutil/win32 directory for WIN32 based
1500 * Added Unix specific network routines to the
1501 lib/silcutil/unix/silcunixnet.c and the old
1502 lib/silcutil/silcnet.c includes now only generic routines.
1504 Added WIN32 specific network routines to the
1505 lib/silcutil/win32/silcwin32net.c.
1507 * Added Unix specific utility functions from the
1508 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1510 * Added WIN32 SILC Scheduler to the file
1511 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1514 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Do not handle JOIN notify in the server if the target client
1517 is not registered (idata->registered == FALSE). The affected
1518 file is silcd/packet_receive.c.
1520 * Update the nickrec->founder in event_cumode in the Irssi SILC
1521 client. Affected file irssi/src/silc/core/silc-channels.c.
1523 * Fixed the CUMODE_CHANGE notify handling in the server when
1524 server and router are announcing their clients on channels.
1525 Now the mode changes are saved and notified correctly. The
1526 affected file is /silcd/packet_receive.c.
1528 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1529 They really did not replace the cache entry in the ID Cache.
1530 Now they do that. Affected file silcd/idlist.c.
1532 * Fixed the KICK notify handling in the Irssi SILC client to
1533 update the channel records so that the kicked client does not
1534 appear to be on the channel. The affected file is
1535 irssi/src/silc/core/silc-channels.c.
1537 * Always update the conn->current_channel when executing command
1538 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1540 * Fixed the KILL notify handling in Irssi SILC client to remove
1541 the killed client on all channels.
1543 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1545 * Fixed the silc_parse_command_line to remove extra spaces
1546 from the start and end of the arguments. Affected file is
1547 lib/silcutil/silcutil.c.
1549 * Cancel and free any active protocol in the function
1550 silc_server_close_connection. Affected file silcd/server.c.
1552 * Cancel and free any active protocol in the function
1553 silc_client_close_connction. Affected file is
1554 lib/silcclient/client.c.
1556 * Do not execute the KILL command for clients that are in
1557 history (ie. they are not in the network). Affected file is
1560 * Fixed KILL notify handling, client does not crash anymore.
1561 Affected file irssi/src/silc/core/silc-channels.c.
1563 * Reduced the default packet buffer size from 2048 to 1024 in
1564 lib/silccore/silcpacket.c.
1566 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1567 counter to the SKE context that is incresed when the SKE library
1568 performs async operation outside the library. If the outside
1569 process frees the SKE context and FREED status will be set
1570 and the library will detect after the sync operation that the
1571 libary is freed. The affected files are
1572 lib/silcske/silcske[_status].[ch].
1574 * Resolve the client entry information in the function
1575 silc_client_channel_message to assure that NULL pointer is not
1576 passed as client entry to the application. */
1578 * Fixed the task timeout calculation to assure that there is
1579 never negative timeouts. The affected file is
1580 lib/silcutil/silcschedule.c.
1582 * Fixed the channel user mode notification sending in server.
1583 It was sent point-to-point to the router (or to server by router)
1584 but it needs to be destined to a channel. The routines now
1585 supports sending the channel user mode notifys to the channels
1586 when announcing clients and channels. Affected files are
1587 silcd/server.c and silcd/packet_receive.c.
1589 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1590 It did not actually replace the old channel entry in the cache.
1591 Affected file lib/silcclient/client_notify.c.
1593 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Fixed a possible crash in silc_packet_send_prepare. It now
1596 assures always that there is enough space in the buffer and
1597 at the tail area of the buffer (for MAC).
1599 Fixed the inbound buffer reallocation in silc_packet_read.
1600 It was old code and did not handle the reallocation correctly.
1603 The affected file is lib/silccore/silcpacket.c.
1605 * Fixed buffer overflow in silc_parse_nickname in the file
1606 lib/silcutil/silcutil.c.
1608 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * make install generates new server keys only if there is not
1613 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1616 Added check that if the NOREPLY is set then we will not send
1617 the away message. This avoids infinite loop of away messages
1618 if both clients are away. The affected file is
1619 lib/silcclient/client_prvmsg.c.
1621 * Fixed client crash if /NICK was given without arguments.
1622 Affected file lib/silcclient/command.c.
1624 * Server does not send the invite list in INVITE command back
1625 to the client if the list was not altered. Added this notion
1626 to the protocol spec as well. Affected file silcd/command.c.
1628 Fixed possible crash in INVITE command by checking the
1629 value of silc_server_get_client_route command.
1631 * Fixed the INVITE notify type handling. The arguments are now
1632 taken in correct order and client does not crash. The affected
1633 file is irssi/src/silc/core/silc-channels.c.
1635 Removed the "Inviting xxx to channel" message from the
1636 client library away and let the application handle it.
1637 Affected file lib/silcclient/command.c. Added that message
1638 to Irssi SILC client's message formats.
1640 * Fixed CMODE command crash in client. It now checks the
1641 amount of arguments correctly and does not crash. The affected
1642 file is lib/silcclient/command.c.
1644 * Do not create new channel automatically in silc_channels_join
1645 but check whether the channel by that name already exists.
1646 Affected file irssi/silc/core/silc-channels.c.
1648 * Do not send the SERVER_SIGNOFF to router if the disconnected
1649 entity was the router. Affected file silcd/server.c.
1651 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1652 SILC client as it was missing from there.
1654 Added the handling of the KICK notify to the Irssi SILC client
1655 as it was missing. Added "you have been kicked" message to
1656 Irssi SILC client's message modules formats.
1658 Added the handing of the KILL notify to the Irssi SILC client
1659 as it was missing. Added the kill message module formats
1662 The affected file is irssi/src/silc/core/silc-channels.c.
1664 * The router did not save the channel mode the server announced.
1665 Affected file silcd/packet_receive.c.
1667 * Fixed a possible crash in INFO command in server. If the
1668 server did not provide the server info it crashed. Affected
1669 file silcd/command.c.
1671 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Fixed the GETKEY command in the server to check also the
1674 global list. Otherwise the GETKEY would not work correctly
1675 in normal SILC server. Affected file silcd/command.c.
1677 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1679 * Fixed GETKEY crash, it crashed if the command did not succseed.
1681 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1684 is now real and not just an macro interface to GMP.
1686 Removed the entire GMP from the source tree and imported new
1687 NSS MPI library instead. Reason for removing GMP is that it is
1688 extremely large and compiles extremely slow. The NSS MPI
1689 is only a few files and compiles in less than 10 seconds.
1690 The speed is also about the same as GMP. The MPI is imported
1691 to lib/silcmath/mpi.
1693 If the system has GMP installed we will still use the GMP.
1694 If it is not then the NSS MPI will be compiled.
1696 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * Merged a long nickname (127 characters long) crash bugfix from
1699 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1701 * Merged a freed memory reference bugfix from Irssi CVS tree.
1702 Affected file irssi/src/core/commands.c.
1704 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Added the server's public key sving and verification to the
1707 server when performing the SKE. This was missing and the
1708 remote server's (or router's) public key was accepted without
1709 checking whether we have it previously or trust it at all.
1710 Affected file silcd/protocol.c.
1712 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Check in the silc_server_timeout_remote if protocol is active
1715 and make sure that the protocol's final callback is called so
1716 that all memory if freed. Affected file silcd/server.c.
1718 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * silc_server_whois_send_reply crashed the server if the nickname
1721 was 127 characters long. Affected file silcd/command.c.
1723 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Added sanity check to the silc_server_new_client. If the hostname
1726 is provided inside username then check that the provided hostname
1727 really is the same as the resolved one. If the hostname was not
1728 resolved then check it from the public key. Affected file is
1729 silcd/packet_receive.c.
1731 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1732 if the server disconnected us and the connection is not valid
1733 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1735 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1736 the library to the lib/silcutil/silcutil.[ch].
1738 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Close log file after open. Affected file
1741 lib/silcutil/silclog.c.
1743 * Check whether sock == NULL in silc_client_send_packet and return
1744 if it is. Affected file lib/silcclient/silcclient.c.
1746 * Check rec->entry == NULL in the Irssi SILC Client before
1747 sending the channel message. Affecte file is
1748 irssi/src/silc/core/silc-servers.c.
1750 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Merged a splitted window bugfix from Irssi CVS tree. The
1753 affected file is irssi/src/fe-text/textbuffer-view.c.
1755 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1756 It did not print nickname.
1758 * Improved the distributions system a bit.
1760 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1763 irssi/src/fe-text/gui-window.c.
1765 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1766 to in-active server. The affected file is
1767 irssi/src/silc/core/client_ops.c.
1769 * Resolve the client in USERS command reply if the entry does
1770 not have username resolved. The affected file is
1771 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1772 command to WHOIS command to really resolve stuff. The USERS
1773 is not used any more in any critical section so WHOIS can
1774 be used even though it might be slower than IDENTIFY.
1776 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1779 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Changed the protocol API a bit more consistent in the
1782 lib/silccore/silcprotocol.[ch].
1784 * Changed the following headers to ROBODoc format:
1786 lib/silccore/silcpayload.h
1787 lib/silccore/silcprotocol.h
1788 lib/silccore/silcsockconn.h
1790 All core library headers are now formatted.
1792 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1794 * Fixed a bug in Irssi SILC client; do not show that you are
1795 server/router operator if you really are not. Affected file is
1796 irssi/src/silc/core/client_ops.c.
1798 * Renamed silc_command_free_payload to silc_command_payload_free.
1799 Affected file lib/silccore/silccommand.h
1801 * Added silcmath.h to include the prototoypes of various routines
1802 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1805 * Changed the following headers to ROBODoc format:
1807 lib/silccore/silcchannel.h
1808 lib/silccore/silccommand.h
1809 lib/silccore/silcid.h
1810 lib/silccore/silcidcache.h
1811 lib/silccore/silcmode.h
1812 lib/silccore/silcnotify.h
1813 lib/silccore/silcpacket.h
1814 lib/silcmath/silcmath.h
1816 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added checking to the server code not to start the server if
1819 ciphers and stuff are not configured properly. Affected files
1820 silcd/serverconfig.[h] and silcd/server.c.
1822 * Changed the layout of the header files of the public interfaces
1823 in the SILC libraries. The new layout supports ROBODoc
1824 documentation tool (and some others) so that it is easy to create
1825 a library reference manual. All the other headers and source
1826 code must still follow the CodingStyle document. Also source
1827 code must not include these ROBODoc stuffs, only the headers.
1828 Furthermore, all public interface headers must now be named
1829 by using `silc' prefix, example: silcapi.h, silccipher.h.
1830 Some files were renamed due to this. All the other headers
1831 must not be used as public interfaces. I will update the
1832 CodingStyle document later. Changed following headers, so far:
1834 lib/silcclient/silcapi.h
1835 lib/silccore/silcauth.h
1836 lib/silccore/silcprivate.h
1837 lib/silccrypt/silcdh.h
1839 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Removed silc_client_packet_send_flush from the client library
1844 as it is not needed. Affected file lib/silcclient/client.[ch].
1846 * Added printing of message of unresolved authentication method
1847 to the Irssi SILC client. Added it to the module formats.
1848 Removed the same message from the client library.
1850 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Added new distribution feature, DISTLABEL. Every distribution
1853 can define own preprocessor label that can be used in the
1854 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1855 file distributions, acconfig.h.pre and prepare.
1857 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Added Makefile.defines_int to include the actual definitions
1860 for Makefile.defines.in. Tested the new distribution system,
1861 created distributions and tested installation.
1863 * Added AWAY message printing to the Irssi SILC client. Added
1864 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1866 * Added SCONNECT command to call the SILC's CONNECT command.
1867 Cannot use CONNECT directly since Irssi uses that internally.
1868 Affected file irssi/src/silc/core/silc-servers.c.
1870 Added ACTION local command. It is same as ME command but takes
1871 the channel as mandatory argument.
1873 Rewrote some of the Irssi's help files to suite for SILC
1876 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1878 * Added Makefile.defines[.in] that should for now on be included
1879 in all Makefile.am file in the source tree. That file includes
1880 all common compilation definitions for SILC source tree.
1882 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1884 * Minor changes to the ./prepare script to change the package
1885 name according the distribution name to the configure.in.
1887 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Created new distribution system. Added file `distributions'
1890 that defines all the distributions that can be created out of
1891 the SILC source tree. The ./prepare script now reads that
1892 file to determine how to prepare the distributions. The
1893 first argument to the ./prepare is the name of the distribution
1894 and second is the version of the distribution. If given
1895 without arguments it creates the default (toolkit) distribution
1896 with the default version (defined in ./prepare).
1898 All Makefile.am files that are subject to the distributions
1899 are now named as Makefile.am.pre. These are ./Makefile.am
1900 and lib/Makefile.am. Others may be changed later.
1902 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1904 * Added invite list, ban list, some key management and connection
1905 error message printing to module formats in the Irssi SILC client.
1907 * Added new silc_client_set_away_message to set the away message
1908 that is back to the person who sent private message. The
1909 affected file lib/silcclient/silcapi.h and the
1910 lib/silcclient/client_prvmsg.c.
1912 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Fixed the private message sending in the Irssi SILC client,
1915 added local command KEY to the Irssi SILC client.
1917 Added key management and key agreement message formats to the
1918 irssi/src/fe-common/silc/module-formats.[ch].
1920 Added USERS (alias WHO) printing, server/router operator
1921 indication and LIST command printing to the module formats.
1923 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Fixed channel joining notify handling, cumode notify handling
1926 from Irssi SILC client.
1928 * Added SILC specific module-formats to the Irssi SILC client so
1929 that SILC specific message hilighting, colors etc is possible.
1930 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1932 Added channel mode, channel user mode, actions, notices,
1933 whois and whowas printing to the the module-formats.c.
1935 * Fixed a bug in channel deletion in the server. The channel
1936 is not left to the cache even if the channel founder auth mode
1937 is set when there are no users anymore on the channel. Affected
1938 file silcd/server.c.
1940 * The silc_net_localhost now resolves the entire hostname including
1941 the domain name. Affected file lib/silcutil/silcnet.c.
1943 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Changed the ask_passphrase client operation to be ascynchronous.
1946 It has now a completion callback and a context that the
1947 application must call after it has got the passphrase from
1948 the user. Affected files lib/silcclient/silcapi.h,
1949 lib/silcclient/protocol.c, lib/silcclient/command.c and
1952 Added SilcAskPassphrase callback that the application calls
1953 to deliver the passphrase to the library.
1955 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1956 The public key verification and especially a certificate
1957 verification is asynchronous procedure.
1959 Added new SILC_SKE_STATUS_PENDING status to indicate the
1960 request is pending and a callback will be called to finalize
1963 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1964 indicate that remote end did not send its public key (or
1965 certificate), even though we require it. Added check for this
1966 condition in the SKE. This was a security bug, now fixed.
1968 Defined new SilcSKEVerifyCbCompletion callback that is called
1969 when the verification process is completed.
1971 The affected files lib/silcske/silcske_status.h and
1972 lib/silcske/silcske.[ch].
1974 * Changed the verify_public_key client operation to be async
1975 as well. Defined SilcVerifyPublicKey callback that is used to
1976 indicate the success of the public key verification process.
1978 Changed the server and client to use the new async client
1981 * Changed the Irssi SILC client's internal scheduler to be called
1982 twice as many times as it used to be. As a result the client
1983 should be a bit faster now. Affected file is
1984 irssi/src/silc/core/silc-core.c.
1986 * Added support to Irssi SILC client of asynchronous public key
1987 verification and passphrase inquiry. Affected file is
1988 irssi/src/silc/core/silc-core.c.
1990 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1992 * Do not say "You have left channel %s" in client library.
1993 Moved it to the application. Affected files are
1994 lib/silcclient/command.c and silc/client_ops.c.
1996 * Fixed silc_client_get_clients. Command context was not
1997 duplicated and was freed memory in the callback. Affected
1998 file lib/silcclient/idlist.c.
2000 * Do not say "you are now talking..." on JOIN command in the
2001 client library. The appliation must handle it.
2003 * Do not say ".. changed topic to" in command reply in the
2004 client libary. The application must handle it.
2006 * Fixed TOPIC command sending in the client library.
2008 * Fixed a memory leak in silc_client_command_free in the file
2009 lib/silcclient/command.c.
2011 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Imported a modified version of Irssi client to the source tree.
2014 The Irssi will be used to create a new client called
2015 Irssi SILC. Imported to irssi/.
2017 Added silc_core_init_finish function to the Irssi. Affected
2018 file irssi/configure.in.
2020 A lot changes in the Makefile.ams around the irssi tree.
2022 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Do not rehash if the new size is same as the old size of the
2025 hash table, in the silc_hash_table_rehash*. The affected file
2026 lib/silcutil/silchashtable.c.
2028 * Replaced hash_table_del_by_context calls from the server
2029 (when channel->user_list and client->channels) to the
2030 hash_table_del as it is sufficient and faster.
2032 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Added silc_hash_table_list, silc_hash_table_get and the
2035 SilcHashTableList structure to provide an alternative way to
2036 traverse the hash table. The affected files are
2037 lib/silcutil/silchashtable.[ch].
2039 * Changed the server's idlist routines to use the hash table
2040 routines to optimize the code.
2042 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Replaced the client entry's `channel' list and channel entry's
2045 `user_list' list to hash tables for optimized lookup. Changed
2046 the code to use the hash table interface around the code.
2047 Affected file lib/silcd/idlist.[ch].
2049 * Added `auto_rehash' boolean argument to the function
2050 silc_hash_table_alloc to indicate whether the hash table should
2051 auto-rehash when it thinks is appropriate time. It will
2052 increase the hash table size if the there is twice as much
2053 entries in the table than the size of the table, and will
2054 decrease the size if there are twice as less entries than
2055 the size of the table.
2057 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2061 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * silc_idcache_purge_by_context deletes the entry now by context
2064 as it is supposed to do. Affected file lib/silccore/idcache.c.
2066 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2067 client is not anymore valid (WHOWAS givens the info) and not
2068 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2070 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2072 * Removed the `data' and `data_len' arguments from the ID Cache
2073 interfaces and added `name' argument. ID Cache does not handle
2074 anymore the binary data only a names associated with given ID.
2076 * When hashing a Client ID with silc_hash_id the entire ID is
2077 not hashed anymore, instead only the hash of the Client ID is
2078 hashed. This way we can access the Client ID from the cache
2079 with Client ID but with the hash of the ID (which is a hash of
2080 the nickname) as well without any difference in performance.
2082 Added also silc_idcache_find_by_id_one_ext to do one on one
2083 searching when we have the actual ID. Added also function
2084 silc_hash_client_id_compare. The affected files are
2085 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2087 * When hashing the name associated with a ID it is always done
2088 in lowercase. This way we can access the cache without worrying
2089 about case-sensitivity, even though, for example nicknames are
2092 * Fixed a bug in server with channel message sending. It put
2093 wrong ID type as destination ID. The affected file
2094 silcd/packet_send.c.
2096 * silc_idcache_del_by_context now deletes from all hash tables
2097 by context. Affected file lib/silccore/idcache.c.
2099 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Changed the client library to use the new ID Cache interface.
2102 Changes around the source tree.
2104 * Added silc_hash_table_rehash_ext to rehash with specific
2105 hash function. Affected file lib/silcutil/silchashtable.[ch].
2107 * Added silc_hash_string_compare to compare two strings in the
2108 hash table. Affected file lib/silcutil/silcutil.[ch].
2110 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added new function silc_idcache_del_by_context into the
2113 lib/silccore/idcache.[ch].
2115 * Changed the server's ID list routines to use the new ID Cache
2116 interface. Changes around the source tree.
2118 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Added silc_hash_table_del[_by_context]_ext functions in to the
2121 lib/silcutil/silchashtable.[ch].
2123 Removed silc_hash_table_find_all* routines and added new
2124 silc_hash_table_find_foreach to replace them.
2126 Added silc_hash_table_replace_ext function as extended
2127 replacing function. Separated the simple hash table interface
2128 from the extended hash table interface in the file
2129 lib/silcutil/silchashtable.h.
2131 * Fixed minor bugs and changed it to use some of the new
2132 hash table functions in lib/silccore/idcache.c
2134 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Added new function silc_hash_table_find_all to return all keys
2137 in the hash table by the specified key. As the hash table is
2138 collision resistant it also makes it possible to have several
2139 duplicate keys in the hash table. This function may be used to
2140 find all of the keys from the hash.
2142 Added user_context arguments to the SilcHashFunction,
2143 SilcHashCompare and SilcHashDestructor to deliver user specified
2146 Added new fuctions silc_hash_table_find[_all]_ext to do
2147 extended lookup with specified hash and compare functions and
2148 specified user contexts.
2150 Added new function silc_hash_table_add_ext to add the key
2151 with specified hash function and user context.
2153 Added new function silc_hash_table_foreach to traverse all
2154 entrys in the hash table. Added SilcHashForeach callback
2157 Added new function silc_hash_table_del_by_context to delete
2158 the entry only if the context associated with the key matches.
2160 Affected files are lib/silcutil/silchashtable.[ch].
2162 * Removed silc_hash_[server/client/channel]_id and added just
2163 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2164 silc_hash_id_compare to compare two ID's using as the hash table
2165 comparison function. Added also silc_hash_data to hash
2166 binary data and silc_hash_data_compare to compare it.
2168 * Removed silc_idlist_find_client_by_hash as it is not needed
2169 anymore. Affected file silcd/idlist.[ch].
2171 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2172 to use internally the SilcHashTable. The new ID Cache is a lot
2173 faster than the old one. Some of the ID Cache interface was also
2174 rewritten and obsolete and stupid functions were removed.
2176 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Added entry_count field to the SilcHashTable to keep the number
2179 of the entries in the table. Implemented the function
2180 silc_hash_table_rehash. Added new function
2181 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2183 Fixed a minor bug in silc_hash_table_free.
2185 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2186 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2187 into the lib/silcutil/silcutil.[ch].
2189 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Implemented a collision resistant hash table into the
2192 lib/silcutil/silchashtable[ch]. See the header and the source
2193 for the SilcHashTable API.
2195 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Merged dotconf version 1.0.2 into lib/dotconf.
2199 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Do not compile anything in lib/silcsim/* if the SIM support
2202 is not enabled. The tree should now compile without problems
2205 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Compiled the SILC under cygwin. Compiled and tested briefly
2208 without problems. More tests needed. The SIMs didn't compile
2211 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2213 * Fixed possible crash in silc_get_username in the
2214 lib/silcutil/silcutil.c.
2216 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2218 * Fixed a va_arg in silc/client_ops.c.
2220 * Oops, RC5 routines were named AES and caused some problems
2221 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2223 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * Added new SilcIDIP structure into the lib/silccore/id.h and
2226 replaced the old `ip' fields from all SILC ID's to that type.
2227 This is a step towards IPv6 support.
2229 The silc_id_get_len takes now the ID as an extra argument.
2230 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2231 both IPv4 and IPv6 based ID's.
2233 The affected files are lib/silccore/id.[ch] and other files
2234 around the tree using these routines.
2236 * Removed the ID length arguments in server from various
2237 silc_server_send_notify_* routines -> they are not needed
2240 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Fixed memory leak in silc_encode_pem_file in the file
2243 lib/silcutil/silcutil.c.
2245 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Check minor version as well in the SKE. Affected files are
2248 silcd/protocol.c and lib/silcclient/protocol.c.
2250 * Added --identifier option to the server so that an identifier
2251 can be when creating the public key for the server. Affected
2252 file is silcd/silcd.c.
2254 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2255 lib/silccrypt/silcpkcs.c.
2257 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Register default ciphers and stuff when using -C option with
2260 the server. Affected file sildc/silcd.c.
2262 * Put back the servers public key filename format, it is better
2263 than the new one. For now, the client keys are saved with the
2264 new filename format. The affected file silc/client_ops.c.
2266 * Implemented the Cipher API for the rest of the ciphers that
2267 did not implement it or implemented it the wrong way.
2269 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Register default ciphers and stuff when using the -S option
2272 in the client. Affected file silc/silc.c. Same also when
2273 creating new key pair with -C option.
2275 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Fixed the silc_verify_public_key client operation function to
2278 save the public keys differently. The fingerprint is now
2279 used as filename and not the hostname. This way also the
2280 client keys are saved uniquely and not with hostnames. The
2281 affected file is silc/client_ops.c.
2283 * Trimmed the silc_hash_fingerprint function to remove extra
2284 whitespaces from the end of the fingerprint. The affected
2285 file is lib/silccrypt/silchash.c.
2289 * Added silc_cipher_register_default function to register all
2290 default ciphers. It can be used when configuration files
2291 does not exist and the application does not want any specific
2292 ciphers in any specific order.
2294 The SilcDList is now used as silc_cipher_list dynamically
2295 allocated cipher list. Removed the static list all together
2296 and now all ciphers must be allocated to the dynamic list.
2297 The silc_cipher_alloc routine was changed to check only the
2300 All silc_cipher_* routines that used to return int returns
2303 The affected files lib/silccrypt/silccrypt.[ch].
2305 * The same thing was done to silc_hash_* as for silc_cipher_*
2306 routines. Affected files lib/silccrypt/silchash.[ch].
2308 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2309 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2310 Added also silc_pkcs_[un]register[_default] functions.
2311 Removed the data_context from the PKCS API.
2313 * Added silc_hmac_register_default function to register default
2314 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2315 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2316 to unregister all hmacs at once.
2318 * Register the default ciphers, hash functions, PKCSs and HMACs
2319 if client's configuration file does not exist. The affected
2322 * The client did not load the hash functions from the SIM
2323 modules at all. Added support for this. Affected file is
2324 silc/clientconfig.c.
2326 * When decoding public key with silc_pkcs_public_key_decode, check
2327 the supported algorithm only if PKCS are registered. Affected
2328 file lib/silccrypt/silcpkcs.c. The same was done with the
2329 silc_pkcs_private_key_decode.
2331 * Fixed the SILC List routines to keep the list always in order.
2332 It used to change the list's order when traversing the list but
2333 not it preserves the order. Affected file lib/trq/silclist.h.
2335 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Added the client library to use the SilcSocketConnection's
2338 reference counter (by silc_socket_dup) to prevent the bug that
2339 the socket object may be freed underneath async operation.
2341 * The name resolv library checking fixes in the configure.in.pre.
2344 * Created new version of the protocol drafts for future
2345 development. The -03 drafts are the ones that will be changed
2346 in the trunk now and the -02 will remain as they are.
2348 * Send list of CUMODE notifys to the router when announcing
2349 the channel users to the router. Affected file silcd/server.c.
2350 If the router receiving channel founder CUMODE for a channel
2351 that already has channel founder it will send CUMODE notify
2352 to the sender to remove the channel founder rights from the
2353 announced client. Affected file silcd/packet_receive.c.
2355 * The CUMODE notify may now use Server ID as well as the entity
2356 who changes the mode. Updated protocool specs.
2358 * Updated INSTALL and README files.
2360 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * New web pages in the http://silc.pspt.fi. The pages was
2367 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Implemented the [DenyConnectin] config section in the server.
2370 Added silc_server_config_denied_conn to check whether incoming
2371 connection is denied. Affected file silcd/serverconfig.[ch].
2373 * Do not check the ports when checking the incoming configuration
2374 data if the port is 0, meaning any. Affected file is
2375 silcd/serverconfig.c.
2377 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Fixed buffer overflow in silc_string_compare in the file
2380 lib/silcutil/silcutil.c.
2382 * Fixed double free in silc_server_command_leave in the file
2385 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2387 * Fixed the version checking in the server. Affected file is
2390 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2392 * Fixed the configuration data fetching when accepting new
2393 connections in the server. Affected file silcd/server.c.
2395 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Added `sender_entry' argument to the function
2398 silc_server_packet_relay_to_channel so that we can check
2399 whether some destination actually belongs to the same route
2400 the sender belongs (ie, we must not resend the packet to the
2401 sender). Affected file silcd/packet_send.[ch].
2403 * Added `servername' field to the SilcClientEntry in the server
2404 to hold the name of the server where client is from. Affected
2405 file is silcd/idlist.h.
2407 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Moved the channel message encrypting in the router betwen
2410 router connections from silc_server_channel_message to the
2411 silc_server_packet_relay_to_channel since we want to check
2412 whether we have anybody channel before encrypting anything.
2413 Affected files silcd/packet_[receive/send].c.
2415 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Fixed the [AdminConnection] server config section to support
2418 multiple entries. Affected file silcd/serverconfig.c.
2420 * Added support into the server to check the validity of the
2421 incoming connection before executing any KE or authentication
2424 * The connection configuration is now saved to the KE and
2425 connection auth protocol contexts and not fetched anymore in
2426 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2428 * The local hosts listenning address and port is also resolved
2429 now when starting the server. We want to have the socket object
2430 to include the real address and port for the listener. Added
2431 new function silc_net_check_local_by_sock into the files
2432 lib/silcutil/silcnet.[ch].
2434 * Fixed a broadcast bug in server -> do not broadcast if we
2437 * Fixed a routing bug. Do not route broadcast packets ever.
2438 Broadcast packets must be processed always and not routed since
2439 they may be destined to some other host than yourself and thus
2440 would get routed without no good reason. Affected file is
2443 * Added function silc_server_config_is_primary_route to check
2444 whether primary router connection has been configured (a router
2445 configuration that we are initiating). If there is not, we
2446 will assume that there is only two routers in the SILC network
2447 and we will use the incoming router connection as our primary
2448 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2450 * Changed the order of the broadcasting. Broadcast _after_ the
2451 packet has been processed not before. Affected file is
2454 * Fixed a [ClientConnection] parsing bug. The port was never
2455 parsed correctly thus resulting to port 0. Affected file
2456 silcd/serverconfig.c.
2458 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2459 argument and did not set the broadcast packet flag. Affected
2460 file silcd/packet_send.c. Fixed same bug in the function
2461 silc_server_send_notify as well.
2463 * If we receive NEW_ID packet for our own ID in the server, ignore
2466 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Removed the nickname from the Private Message Payload.
2471 Updated the code and the protocol specs.
2473 * Updated protocol specs for submitting to the IETF.
2475 * Tweaked the Random Number Generator a bit. Affected file
2476 lib/silccrypt/silcrng.c. Exported a new function
2477 silc_rng_[global]_add_noise which can be used to add more
2480 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2482 * Do not parse packets with different timeout when protocol
2483 is active -> may cause problem with rekey. Affected file
2486 * When server receives signoff notify it must not create
2487 new channel key if the client is on any channels since the
2488 sender of the signoff notify will create it.
2490 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Added printing of error messages during SKE protocol from the
2493 failure packet sent by server during SKE. Affected file
2496 * Removed the client's failure_callback handling with timeout
2497 and handle it immediately when received.
2499 * The SKE library returned wrong type in SUCCESS and FAILURE
2500 packets. They must be 32 bit MSB not 16 bit MSB.
2502 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Ok, rewrote the logic of the re-key and now it seems to work.
2505 I tested it on high traffic with frequent re-keys without
2506 problems. Added hmac_receive (and renamed hmac to hmac_send)
2507 in SilcClientConnection in lib/silcclient/client.h and
2508 in SilcIDListData in silcd/idlist.h. Also, removed the
2509 SilcPacketParserContext's cipher and hmac fields as they are
2510 not needed anymore and actually caused some problems when
2511 the ciphers and hmac's changed underneath the packet parser.
2513 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * If re-key protocol is active then process the incoming packets
2516 synchronously since we must assure that icoming packets encrypted
2517 with the old key is processed before the new keys is set to
2518 use. This is true other packets than for REKEY packets.
2519 Affected file silcd/server.c. The same was done to client library
2520 as well, affected file lib/silcclient/client.c.
2522 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Fixed bug in client and server to accept the force send if
2525 the packet is send from silc_[server/client]_packet_process
2526 function. Otherwise the packets are never delivered, oops.
2528 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2530 * Disable force sending of packets when REKEY protocol is active.
2531 We must assure that no packet is sent directly when rekey is
2532 performed. All packets must be sent through packet queue.
2533 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2534 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2535 function is silc_[server/client]_packet_send_real to check
2538 * Replaced the SIM paths from example config files to
2539 /usr/local/modules. Also, make install creates now
2540 /usr/local/silc/logs directory to hold all the SILC server
2543 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Made the configure.in.pre work on Solaris. Patch by salo.
2547 * Made all ciphers compatible with non-x86 machines. Defined
2548 CBC mode macros into lib/silccrypt/ciphers_def.h.
2550 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Fixed the make install.
2554 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * When MAC computation fails the silc_packet_decrypt returned 0
2557 even though it was supposed to return -1. Fixed this. The
2558 affected file is lib/silccore/silcpacket.c.
2560 * Do not replace the config files in /etc/silc (in make install)
2561 if they already exist. Affected file ./Makefile.am.
2563 * Do not send re-key packets immediately but through packet queue.
2564 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2566 * Changed silc_net_check_host_by_sock to return FALSE if the
2567 IP/DNS could not be resolved. Though, it returns the IP address
2568 now even if it could not resolve it (but returns also FALSE).
2569 Affected file lib/silcutil/silcnet.[ch].
2571 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Added silc_pkcs_decode_identifier to decode the public key's
2574 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2575 Added also silc_pkcs_free_identifier. Added also new context
2576 SilcPublicKeyIdentifier.
2578 * Added -S option to the silc client. It is used to dump the
2579 contents of the specified public key file.
2581 * Changed the PKCS api to return the public key length when
2582 setting the public key.
2584 * Fixed a fatal bug in the public and private key file loading.
2585 Affected file lib/silccrypt/silcpkcs.c.
2587 * Execute the packet parsing for client with zero (0) timeout
2588 if the protocol is active. Affected file silcd/server.c.
2590 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Made the key generation options to the silcd program. Added
2593 -C option, equivalent to client's option.
2595 * Added new [ServerKeys] config section to the server. It
2596 configures the server's public and private key.
2598 * Defined generic Public Key Payload into the protocol
2599 specification to send specific type of public keys and
2602 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2603 public key or certificate.
2605 * Implemented the GETKEY command to the server and to the
2606 client library and on user interface.
2608 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Made preliminary `make install' work.
2612 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Added SilcServerRekey context into silcd/idlist.h.
2616 * Added the PFS support as defined in the specification to the
2617 SKE protocol. Affected files lib/silcske/*.c.
2619 * Added `ske_group' field to the SilcServerRekey context to hold
2620 the number of the SKE group that is used with PFS in re-key.
2621 Affected file silcd/idlist.h.
2623 * Added PFS re-key support to the server. Affected file is
2626 * Added silc_protocol_cancel to cancel execution of the next
2627 state of the protocol. Affected file is
2628 lib/silccore/silcprotocol.[ch].
2630 * Added the re-key support with and without PFS to the client
2631 library. Re-key is performed once in an hour, by default.
2633 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2634 Added silc_client_rekey_callback and silc_client_rekey_final.
2635 Affected files are lib/silcclient/protocol.[ch] and
2636 lib/silcclient/client.[ch].
2638 * Removed the `hmac_key' and `hmac_key_len' fields from the
2639 SilcClientConnection structure; not needed. Affected file is
2640 lib/silcclient/client.h.
2644 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Do not ask whether user wants to use the negotiated private key
2647 for private messages, just use it. Affected file is
2648 silc/local_command.c.
2650 * Added `send_enc_key' and `enc_key_len' fields to the
2651 SilcIDListData structure since they are needed in the re-key
2652 phase. Affected file is silcd/idlist.[ch].
2654 * Implemented the simple re-key protocol into the server.
2655 Affected files silcd/server.c and silcd/protocol.[ch]. The
2656 re-key will be performed once in an hour, by default.
2658 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2659 Added silc_server_rekey, silc_server_rekey_callback and
2660 silc_server_rekey_final.
2662 * Removed Tunneled flag from the protocol. Updated the code
2663 and the specifications.
2665 * Adde `pfs' field to the SilcIDListData to indicate whether
2666 the PFS is to be performed in the re-key. Affected file is
2669 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2672 int64 of at least the xintXX size. If void * is less that 4
2673 bytes uint32 * will be used. Defined bool as boolean.
2675 * Changed _ALL_ unsigned long and unsigned int to uint32,
2676 unsgined short to uint16 in the source tree.
2678 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2679 not handle clients that has entry->data.registered == FALSE.
2680 They are not in the network anymore. Affected file is
2683 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Implemented the sending of the SERVER_SIGNOFF notify in the
2686 server. Affected file is silcd/server.c.
2688 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2689 Added also silc_notify_payload_encode_args into the
2690 lib/silccore/silcnotify.[ch].
2692 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2693 Affected file silcd/packet_receive.c.
2695 * Implemented the SERVER_SIGNOFF notify handling in the client
2696 library. Affected file lib/silcclient/client_notify.c. Also,
2697 implemnted the printing of the SERVER_SIGNOFF info to the
2698 application. Affected file silc/client_ops.c.
2700 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2701 if the deleting was successful. Affected file silcd/idlist.[ch].
2703 * Added support for public key authentication in the connection
2704 authentication protocol in the client library. Affected file
2705 lib/silcclient/protocol.c.
2707 * Changed the server's silc_idlist_get_clients_by_* interface
2708 to support already allocated array so that new entries may be
2709 added to pre-allocated array. Affected file silcd/idlist.[ch].
2710 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2711 and command replies.
2713 * All command reply functions in the server now calls the
2714 pending command callback even if error occured. This way the
2715 error will be delivered to the client as well. Affected files
2716 silcd/command.c and silcd/command_reply.c.
2718 * Fixed INFO command to return local server's info if no server
2719 was provided. Affected file lib/silcclient/command.c.
2721 * Removed RESTART command for good. Updated the code and the
2724 * Rewrote parts of the task system. It is a bit simpler now.
2725 Removed unsued task priorities. The affected files are
2726 lib/silcutil/silctask.[ch].
2728 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2730 * Moved the USERS printing from the library to the application.
2731 Affected files lib/silcclient/command.c and silc/client_ops.c.
2733 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Added channel key re-key support. The re-key is perfomed
2738 only by the router and is done once in an hour. Added `rekey'
2739 field to the SilcChannelEntry in the server. Affected files
2740 silcd/server.c and silcd/idlist.h.
2742 * Added silc_task_unregister_by_context into the file
2743 lib/silcutil/silctask.[ch].
2745 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Added SILC_UMODE_GONE mode to indicate when the client is not
2748 present in the SILC network. Added also support to the local
2749 command AWAY that will set this mode. Added support of showing
2750 "xxx is gone" in WHOIS command. The USERS command shows the
2751 gone status as well.
2753 * Fixed setting server and router operator privileges in the
2754 server's UMODE command. Affected file silcd/command.c.
2756 * Merged the SKE KE1 and KE2 payloads into one payload. The
2757 new KE payload is equivalent to the old KE2 payload.
2759 Cleaned up the SKE Start Payload parsing. It now uses the
2760 simple buffer unformatting to do the parsing. A lot faster
2763 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2764 to the SKE that is used to indicate whether both of the SKE
2765 parties should perform authentication. By default only the
2766 responder performs authentication. By setting this flag also
2767 the initiator must do authentication. By default it is unset
2768 since in normal SKE case, client to server connection, only
2769 the responder should do authentication. When doing SKE between
2770 two clients both should perform authentication. Updated the
2771 code and the protocol specs.
2773 * A little fix to IDENTIFY command in the server. Search the
2774 client first by hash not nickname. Affected file is
2777 * Fixed the silc_client_close_connection to support closing
2778 the client to client connections wihtout deleting too much
2779 data. Affected file lib/silcclient/client.c.
2781 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2782 are received if protocol used to be active but is not anymore
2783 the application would crash due to NULL pointer dereference.
2784 Affected files silcd/server.c and lib/silcclient/client.c.
2786 * Added `hash' field to the SilcClientConnection to include
2787 the hash function negotiated in the SKE protocol.
2789 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2790 to set the channel founder authentication data. A client can
2791 claim the founder rights later by providing the authentication
2792 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2793 This way the channel founder can regain the channel founder
2794 privileges even it is left the channel. This works only on
2795 local server and the client must be connected to the same
2796 server to be able to regain the founder rights. Updated the
2797 protocol specs accordingly.
2799 Added support to the CMODE command in the client to set the
2800 founder auth data. Read the README to see how to set it.
2802 Added support to the CUMODE command to claim the founder
2803 rights. Read the README to see how to do it.
2805 Added support for the founder authentication to the Channel
2806 Entry in the server. Affected file silcd/idlist.h.
2808 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2809 server's CMODE command. Affected file silcd/command.c.
2811 * Added the following new functions into lib/silccore/silcauth.[ch]:
2812 silc_auth_get_method and silc_auth_get_data.
2814 * The server now saves the remote hosts public key to the
2815 SilcIDListData pointer. Affected file silcd/protocol.c.
2817 * The normal server now does not remove the channel entry from
2818 the cache if the founder authentication data is set. It used
2819 to remove it if the founder was the last one on the channel on
2820 the server and left the channel. The auth data is saved and
2821 if the channel is re-joined later the old entry is used with
2822 the old auth data. Affected files silcd/command_reply.c and
2825 * Removed the `pkcs' field from the SilcIDListData structure
2826 in the server; it is not used. Affected file silcd/idlist.h.
2828 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Fixed packet processing on slow links. Partial packets were
2831 never re-processed because the incoming data buffer was cleared
2832 by the application. Application must not directly clear the
2833 sock->inbuf, the packet processing routines handle it. Fixed
2834 this in client library and in server.
2836 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Fixed the WHOIS and IDENTIFY send reply function to really
2839 check whether to send list or just one entry. Affected file
2842 * Cleaned up the LEAVE command's channel key distribution. The
2843 affected file silcd/command.c.
2845 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2846 can enforce the channel mode as well. In that case the ID
2847 includes the ID of the server. The code now enforces the
2848 mode change if the router have different mode than the server.
2850 * The notify client operation with CMODE_CHANGE notify can now
2851 return NULL client_entry pointer if the CMODE was not changed
2852 by client. Application must check for this.
2854 * Added <Server ID> argument to INFO command to support server
2855 info fetching by Server ID.
2857 * Added silc_server_announce_get_channel_users to get assembled
2858 packets of channel users of the specified channel. Affected
2859 file silcd/server.[ch].
2861 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2862 was freed underneath the ID Cache.
2864 * Re-announce clients when the server received CHANNEL_CHANGE
2865 notify from the router. Affected file silcd/packet_send.c.
2867 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2870 crashed since it did not handle the fact that there is no cipher
2871 called "3" and didn't check the error condition. Now fixed.
2873 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2874 flag. It can be used to send message requests.
2876 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Implemented the RESTART command in the client.
2880 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2881 notice type messages. Added notice printing to the user
2884 * The channel keys are not re-generated if the channel's mode
2885 is PRIVKEY, ie private key on the channel exists. Affected
2886 files silcd/server.c and silcd/command.c.
2888 * Fixed a little bug in channel message delivery when channel
2889 private keys are set in the server. Affected file is
2890 silcd/packet_send.c.
2892 * Changed the setting on channel->on_channel = TRUE from the
2893 silc_client_save_channel_key to the JOIN command reply. The
2894 key payload is not received if the private channel key is set.
2895 Affected file lib/silcclient/command_reply.c and the
2896 lib/silcclient/client_channel.c.
2898 * When the CMODE_CHANGE notify is sent and the channel private
2899 key mode is removed the channel key must be re-generated in
2900 other cells as well. Added this support for the router in the
2901 silcd/packet_receive.c.
2903 * Added new local command NOTICE to send notice message on
2904 channel. Affected file silc/local_command.[ch].
2906 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Added new local command ME to the client. It is used to send
2909 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2910 some action. Affected file silc/local_command.[ch].
2912 * Changed channel_message and private_message client operations
2913 to deliver the message flags to the application. Added also
2914 the `flags' arguments to the silc_client_send_channel_message
2915 and silc_client_send_private_message functions. Affected file
2918 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Redefined the Private Message Payload to support private message
2921 keys and to support the new private message flags. Updated
2922 the protocol specs. Flags makes it possible to have for example
2923 CTCP style messages.
2925 * Added new type SilcPrivateMessagePayload and defined an API
2926 for it in the lib/silcclient/silcprivate.[ch].
2928 * Tested private message private keys successfully. Tested the
2929 private message key set, unset and list commands with the new
2932 * Redefined the Channel Message Payload to include the channel
2933 message flags (equal with private message flags) to support
2934 for example CTCP style messages.
2936 * Defined some of the message (for channel and private message)
2937 flags. Updated the protocol specs and added the flags to the
2938 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2940 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Added SilcKeyAgreementStatus type to the key agreement routines
2943 to indicate the current status and error if one occured.
2944 The status types are defined in the lib/silcclient/silcapi.h.
2946 * Added new local command KEY that is used to set and unset private
2947 keys for channels, set and unset private keys for private messages
2948 with remote clients and to send key agreement requests and
2949 negotiate the key agreement protocol with remote client. The
2950 key agreement is supported only to negotiate private message keys,
2951 it currently cannot be used to negotiate private keys for channels,
2952 as it is not convenient for that purpose.
2954 * Fixed a minor pending callback setting bug in the function
2955 silc_client_get_client_by_id_resolve, now the function works.
2956 Affected file lib/silcclient/idlist.c.
2958 * Added function silc_net_get_local_port to get local bound
2959 port by socket. Added to lib/silcutil/silcnet.[ch].
2961 * Added `sockets' and `sockets_count' fields to the SilcClient
2962 object. They hold the sockets of the listenning sockets in
2963 the client. Listenning sockets may be for example the key
2964 agreement server. Affected file lib/silcclient/client.[ch].
2965 Added functions the silc_client_add_socket and the
2966 silc_client_del_socket. They are exported to the application
2969 * Added ~./silc/clientkeys to support other client's public keys.
2971 * Renamed verify_server_key client operation to verify_public_key
2972 and added one argument to indicate the type of the connection
2973 (server, client etc.).
2975 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Added silc_server_connection_auth_request to handle the
2978 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2979 silcd/packet_receive.[ch].
2981 * Added silc_server_send_connection_auth_request into the
2982 silcd/packet_send.c to send the connection auth request packet.
2984 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2987 * Fixed the public key authentication in responder side in the
2988 server. The `auth_data' pointer includes the SilcPublicKey
2989 not the path to the public key. Affected file silcd/protocol.c.
2991 * Implemented the public key authentication in the initiator side
2992 in the server. Affected file silcd/protocol.c.
2994 * Removed the [RedirectClient] config section from the server
2995 configuration. Is not needed and I don't want to implement it.
2997 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Cleaned up the CMODE command in the server. It now works
3000 correctly and supports all the modes defined in the protocol.
3001 Affected file is silcd/command.c.
3003 * Added `hmac_name' field to the SilcChannelEntry in the server
3004 to hold the default HMAC of the channel. It can be set when
3005 creating the channel (with JOIN command). Affected files
3008 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3009 type to indicate the change of the current cipher and hmac
3010 on the channel. Client can safely ignore the <cipher> argument
3011 (if it chooses to do so) since the CHANNEL_KEY packet will
3012 force the channel key change anyway. The <hmac> argument is
3013 important since the client is responsible of setting the new
3014 HMAC and the hmac key into use.
3016 * Fixed the CMODE command in the client library as well.
3018 * Tested CMODE command in router environment successfully.
3020 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Show the version of the remote client (or server) when connecting
3023 to the server. It is logged to the log file. Affected file
3024 is silcd/protocol.c.
3026 * Fixed the KILLED notify handling in the client library. The
3027 client must be removed from all channels when receiving the
3030 Also, do not remove the client entry when giving the KILL
3031 command but when the KILLED notify is received.
3033 * Removed silc_idlist_find_client_by_nickname from the server.
3034 Not needed anymore. Affected files silcd/idlist.[ch].
3036 * Implemented the CHANNEL_CHANGE notify type handling to the
3037 server. Affected file silcd/server.c.
3041 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Added silc_server_send_notify_invite to send the INVITE
3044 notify between routers.
3046 * Implemented the INVITE command correctly to the server.
3048 * Implemented the INVITE notify type handling in the server.
3050 * Implemented the INVITE command to the client library and on the
3053 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Added function silc_server_get_client_resolve to find the
3056 client entry by ID from all ID lists and then resolve it
3057 (using WHOIS) if it cannot be found. Affected file is
3060 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Implemented the BAN command to the client library.
3064 * The JOIN command in the server now checks the invite list
3067 * Changed the silc_command_reply_payload_encode_va and the
3068 silc_command_payload_encode_va to support that if argument is
3069 NULL it ignores and checks the next argument. Affected file
3070 lib/silccore/silccommand.c.
3072 * Added silc_server_send_notify_ban to send the BAN notify
3073 type between routers.
3075 * Chaned the silc_notify_payload_encode to support that if
3076 argument is NULL it ignores and checks the next argument.
3077 Affected file lib/silccore/silcnotify.c.
3079 * Tested ban lists in router environment successfully.
3081 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Implemented BAN command to the server, in silcd/command.[ch].
3085 * Removed the BAN and INVITE_LIST modes from the CMODE command
3088 * Added function silc_string_match to regex match two strings.
3089 Affected files lib/silcutil/silcutil.[ch].
3091 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Redefined parts of the SilcChannelEntry in the server to support
3094 the new ban and invite lists.
3096 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Redefined the INVITE command. The same command can be used to
3099 invite individuals to the channel but also to manage the invite
3100 list of the channel (to add to and remove from the invite list).
3101 Updated the protocol specs.
3103 * Added new command SILC_COMMAND_BAN that can be used to manage
3104 the ban list of the channel. Updated the protocol specs.
3106 * Removed the channel modes: the SILC_CMODE_BAN and the
3107 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3108 in the CMODE command. The equivalent features are now available
3109 using INVITE and BAN commands. Updated the protocol specs.
3111 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3112 in the network about change in the current ban list. The notify
3113 type is not used by the client.
3115 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3116 support the invite lists.
3118 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added new function silc_string_regexify that converts string
3121 including wildcard characters into regex string that can
3122 be used by the GNU regex library. Added into the file
3123 lib/silcutil/silcutil.[ch].
3125 Added silc_string_regex_combine to combine to regex strings
3126 into one so that they can be used as one regex string by
3127 the GNU regex library. Added into the file
3128 lib/silcutil/silcutil.[ch].
3130 Added silc_string_regex_match to match two strings. It returns
3131 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3133 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Imported GNU regex to the soruce tree into lib/contrib.
3136 Fixed some compiler warning from the regex.c.
3138 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Fixed MOTD command in the server to work in router environment.
3142 * Fixed the MOTD command in the client library to support
3143 the server argument in the command.
3145 * Added `nickname_len' argument to the silc_idlist_add_client
3146 in the server, as the `nickname' argument may be binary data
3149 * Added silc_idlist_get_channels to return all channels from
3152 * Implemented LIST command to the server. Affected file is
3155 * Implemented the LIST command to the client library and on the
3158 * Added [<user count>] argument to the LIST command reply.
3159 With private channels the user count is not shown.
3161 * Updated TODO and README.
3163 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * The client entry's data.registered must be TRUE even with
3166 global client entry on global client list. The data.registered
3167 is used to check whether the client is anymore in the network,
3168 for example with WHOWAS command so it must be valid.
3170 * Fixed the WHOWAS command in the server. It now actually works
3171 in router environment. Added function into silcd/command_reply.c
3172 silc_server_command_reply_whowas_save.
3174 * Added silc_idlist_purge function to the silcd/idlist.c
3175 to periodically purge the ID Cache.
3177 * Fixed INFO command in the server. It works now in router
3178 environment. Added <server name> argument to the INFO command
3179 reply. Updated the protocol specs.
3181 * Fixed minor bug in silc_idcache_purge to not purge if the
3182 expire value is zero.
3184 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3185 they were buggy because of the WHOWAS information.
3187 * Fixed local command MSG to handle the async resolving of
3188 the remote client properly. It used to fail the first MSG.
3189 Affected file silc/local_command.c.
3191 * Added `data_len' field to SilcIDCache context.
3193 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Update TODO. Todo in commands in the server.
3197 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3200 used by routers as broadcast packet to inform other routers
3201 about the changed user mode.
3203 Implemented the notify handling in the server. Affected file is
3204 silcd/packet_receive.c. Added the function
3205 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3207 * Added new generic Channel Payload and deprecated the New Channel
3208 Payload. The New Channel Payload is now the generic Channel
3211 * Added new argument `mode' to the silc_server_send_new_channel
3212 as it is required in the Channel Payload now.
3214 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3215 and created a new and real SilChannelPayload to represent the
3216 new generic Channel Payload. Implemented the encode/decode
3217 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3219 * Added silc_server_get_client_channel_list to return the list
3220 of channels the client has joined for WHOIS command reply.
3221 Affected file silcd/server.[ch].
3223 * Implemented the channel list sending in the WHOIS command reply
3224 in server and in the client.
3226 Implemented the channel list displaying on the user interface
3227 as well. Affected file silc/client_ops.c.
3229 * Added silc_channel_payload_parse_list to parse list of Channel
3230 Payloads. It returns SilcDList list of SilcChannelPayloads.
3231 Client for example can use this function to parse the list of
3232 channels it receives in the WHOIS command reply. The caller
3233 must free the list by calling silc_channel_payload_list_free.
3234 Affected files lib/silccore/silcchannel.[ch].
3236 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Added one new argument <user mode> to the WHOIS command reply
3239 to return the mode of the user in SILC. Updated the protocol
3242 Implemented it to the server and client.
3244 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Fixed the mode printing on the user interface on joining.
3247 Affected file silc/client_ops.c.
3249 * Implemented the UMODE command and user modes in general to the
3250 client library and to the user interface.
3252 * Implemented the UMODE command to the server.
3254 * The server now sends UNKNOWN_COMMAND error status if client sends
3255 unknown command. Affected file silcd/command.c.
3257 * All server commands now handle the command identifier the right
3258 way when sending the command reply to the client. The client can
3259 use to identify the command replies with the identifier.
3261 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added silc_server_get_client_route to resolve the route to
3264 the client indicated by the client ID. Affected file is
3267 * Added silc_server_relay_packet as general function to relay
3268 packet to arbitrary destination. This deprecates functions
3269 like _send_private_message_key, _relay_notify etc. Affected
3270 file is silcd/packet_send.[ch].
3272 Removed silc_server_send_key_agreement,
3273 silc_server_send_private_message_key and
3274 silc_server_packet_relay_notify functions from the file
3275 silcd/packet_send.[ch].
3279 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3280 server. Affected file silcd/packet_receive.[ch].
3282 * Implemented the KILL command to the client. Implemented the
3283 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3284 Affected files lib/silcclient/command[_reply].c and
3285 lib/silcclient/client_notify.c. Implemented the KILL notify
3286 printing in the user inteface.
3288 * Fixed a lot silc_parse_nick memory leaks from the client
3289 library in the file lib/silcclient/command.c.
3291 * Changed the silc_server_send_notify_on_channels's `sender'
3292 argument from SilcSocketConnection to SilcClientEntry to
3293 check the sender as entry and not as connection object and not
3294 to send to the client provided as argument. The affected file
3295 is silcd/packet_send.[ch].
3297 * The notify packets that are destined directly to the client used
3298 to not to be processed by the server. Now changed that and the
3299 server processes all notify packets. After relaying the packet
3300 to the client the notify packet is processed in the server.
3302 * The silc_server_free_client_data now checks whether there is
3303 pending outgoing traffic for the client and purges the data to
3304 the network before removing the client entry.
3306 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3309 an client is killed from the SILC Network. Updated the protocol
3312 Added new function silc_server_send_notify_killed to the
3313 silcd/packet_send.[ch].
3315 * Added function silc_server_packet_relay_notify to relay notify
3316 packets that are destined directly to a client. In this case
3317 the server does not process the notify packets but merely relays
3318 it to the client. Affected file silcd/packet_send.[ch].
3320 Added also silc_server_packet_process_relay_notify to check
3321 whereto relay the notify. Affected file is
3322 silcd/packet_receive.[ch].
3324 * Implemented the KILL command to the server.
3328 * Added the backup schema desgined last fall to the protocol
3329 specs for everyone to see. The specification is in the
3330 *-spec-xx.txt draft and the packet type definitions for the
3331 backup routers is in *-pp-xx.txt draft. Thusly, added also
3332 new packet type SILC_PACKET_CELL_ROUTERS.
3334 * A big security problem in the implementation discovered. The
3335 signoff of an client did not cause new channel key generation
3336 which it of course should've done. The channel keys must be
3337 always re-generated when client leaves (or signoffs) the channel.
3338 The silc_server_remove_from_channels funtion now handles
3339 the channel key re-generation.
3341 * Added `sender' argument to the silc_server_send_notify_on_channels
3342 to not to send the client provided as argument. Affected file
3343 silcd/packet_send.[ch].
3345 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Implemented OPER and SILCOPER commands into the server and
3350 * Added silc_auth_verify and silc_auth_verify_data to verify
3351 the authentication directly from the authentication payload.
3352 It supports verifying both passphrase and public key based
3353 authentication. Affected file lib/silccore/silcauth.[ch].
3355 * Added `hash' field to the SilcIDListData structure. It is the
3356 hash negotiated in the SKE protocol. Affected file is
3359 * Slight redesigning of the SilcAuthPayload handling routines.
3360 Do not send SilcPKCS but SilcPublicKey as argument.
3362 * Implemented the public key authentication support to the
3363 serverconfig. The public key is loaded from the provided path
3364 and saved as authentication data to void * pointer. Thus,
3365 changed the unsigned char *auth_data to void *auth_data;
3367 * Fixed SHUTDOWN command to send the reply before the server
3368 is shutdown. :) Affected file silcd/command.c.
3370 * Fixed fatal bug in CONNECT command. The hostname was invalid
3371 memory and server crashed. Affected file silcd/command.c.
3373 * Fixed fatal bug in CLOSE command. The server_entry became
3374 invalid but was referenced later in the command. Affected file
3377 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Fixed fatal bug in failure packet handling. Server ignored
3380 the failure and thus crashed when it came.
3384 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3387 that the command may be executed only once in (about) 2 seconds.
3388 The old SILC_CF_LAG flag is same but allows command bursts up
3389 to five before limiting.
3391 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3392 server code. Various commands now includes the CF_LAG_STRICT
3393 flag to disallow any kind of miss-use of the command.
3395 * Fixed the silc_buffer_unformat to not to allocate any data
3396 if the length of the data is zero. It used to allocate the
3397 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3399 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Changed the format of AdminConnection configuration section
3402 in the server. Added username of the admin to the format.
3403 Affected files silcd/serverconfig.[ch].
3405 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3406 to return admin configuration data by host, username and/or
3409 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Implemented WHOWAS command to the server. Added the functions:
3413 silc_server_command_whowas_parse,
3414 silc_server_command_whowas_send_reply,
3415 silc_server_command_whowas_from_client and
3416 silc_server_command_whowas_from_server
3418 * Added <Client ID> argument to the WHOWAS command reply. Updated
3419 the protocol specs accordingly.
3421 * Implemented WHOWAS command and command_reply to the client
3424 Implemented the WHOWAS printing on the user interface.
3426 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Added new argument to the WHOWAS command reply, the real name.
3429 It is an optional argument. Updated the protocol specs.
3431 * Added SilcIDCacheDestructor callback that is registered when
3432 the SilcIDCache is allocated. The callback is called when
3433 an cache entry in the ID Cache expires, or is purged from the
3434 cache. Added into lib/silccore/idcache.[ch].
3436 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3437 to destruct the client entries when the cache entry expires.
3438 Other ID Cache's in server and in the client library ignores
3441 * If the ID Cache entry's `expire' field is zero then the entry
3442 never expires. Added boolean `expire' argument to the
3443 silc_idcache_add function in the lib/silccore/idcache.[ch].
3444 If it is TRUE the default expiry value is used.
3446 * Added silc_server_free_client_data_timeout that is registered
3447 when client disconnects. By default for 5 minutes we preserve
3448 the client entry for history - for WHOWAS command.
3450 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Added support to the server to enforce that commands are not
3453 executed more than once in 2 seconds. If server receives
3454 commands from client more frequently, timeout is registered
3455 to process the commands. Affected file silcd/command.c.
3456 Added new function silc_server_command_process_timeout.
3458 * Changed NICK_NOTIFY handling in client library to check that
3459 if the client's nickname was changed, so there is no need to
3460 resolve anything from the server.
3462 * Removed error printing from the WHOIS and IDENTIFY commands.
3463 If error occurs then it is ignored silently in the client library.
3464 The application, however, may map the received error to
3465 human readable error string. The application currently maps
3466 the NO_SUCH_NICKNAME error to string.
3468 * Made the command status message public to the application. Moved
3469 them from lib/silcclient/command_reply.c to
3470 lib/silcclient/command_reply.h. The application can map the
3471 received command status to the string with the
3472 silc_client_command_status_message function.
3474 * Added check to the server to check that client's ID is same
3475 as the Source ID in the packet the client sent. They must
3478 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added dist-bzip hook to the Makefile.am to make bzip2
3481 compressed distributions.
3483 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Server now enforces the maximum length for the nickname and
3486 the channel as protocol specification dictates. 128 bytes for
3487 nickname and 256 bytes for channel name.
3489 * Moved the WHOIS printing to the application. The client libary
3490 does not print out the WHOIS information anymore, the application
3491 must do it. Renamed silc_client_command_reply_whois_print to
3492 the silc_client_command_reply_whois_save.
3494 The client's idle time is also sent to the application now, and
3495 the idle is shown on screen.
3497 * Added silc_client_command_reply_identify_save to save the
3498 received IDENTIFY entries.
3500 * Do not check for channel private keys in message sending and
3501 reception if the channel does not have the PRIVKEY mode set.
3502 Affected file lib/silclient/client_channel.c.
3504 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3507 just surfaced after chaning the JOIN procedure.
3509 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Added silc_client_get_clients_by_list to get client entries
3512 from Client ID list, that is returned for example by JOIN
3513 and USERS command replies. The application should use this
3514 function for example when JOIN command reply is received to
3515 resolve the clients already on the channel (library does not
3516 do that anymore as USERS command reply is not used in the JOIN
3517 procedure anymore). Affected files lib/silcclient/silcapi.h and
3518 lib/silcclient/idlist.c.
3520 * JOIN command reply and USERS command reply returns now SilcBuffer
3521 pointers instead of unsigned char pointers when returning
3522 the client list and mode list.
3524 * Added <Client ID> argument to the JOIN command reply, mainly
3525 for the server to identify for which client the command was
3526 originally sent. Updated protocol specs accordingly.
3528 * Added SilcDlist private_key pointer to the SilcChannelEntry
3529 in the client to support the channel private keys. Affected
3530 file is lib/silcclient/idlist.h.
3532 * Added SilcChannelPrivateKey argument to the function
3533 silc_client_send_channel_message so that application can choose
3534 to use specific private ke if it wants to. If it is not provided,
3535 the normal channel key is used, unless private keys are set.
3536 In this case the first (key that was added first) is used
3537 as the encryption key.
3539 * Implemented the support for channel private key handling.
3540 Implemented the following functions:
3542 silc_client_add_channel_private_key,
3543 silc_client_del_channel_private_keys,
3544 silc_client_del_channel_private_key,
3545 silc_client_list_channel_private_keys and
3546 silc_client_free_channel_private_keys
3548 Affected file lib/silcclient/client_channel.c.
3550 * Added the support for the private keys in the channel message
3551 sending and encryption and in the message reception and
3552 decryption. Affected funtions are
3553 silc_client_send_channel_message and silc_client_channel_message.
3555 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Added SKE's key verify callback to the client library's
3558 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3560 * Removed the statement that server (or router) must send USERS
3561 command reply when joining to the channel so that the client
3562 knows who are on the channel. Instead, the client list and
3563 client's mode list is now sent in the JOIN command reply to the
3564 client who joined channel. This is better solution.
3566 * Added function silc_server_get_users_on_channel and function
3567 silc_server_save_users_on_channel to the silcd/server.[ch].
3569 * Removed function silc_server_command_send_users from the
3572 * Do not show topic on the client library anymore. The topic is
3573 sent in the command reply notify to the application and the
3574 application must show the topic now.
3576 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Added client searching by nickname hash into the IDENTIFY and
3579 WHOIS commands in the server as they were clearly missing from
3580 them. Affected file is silcd/command.c.
3582 * Fixed a bug in private message receiving in the client library.
3583 The remote ID was freed and it wasn't supposed, now it is
3586 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Minor fix to the channel payload; allocate the data area, as it
3589 needs to be of specific length.
3591 * If the key agreement port is zero then the operating
3592 system will define the bound port. Affected files are
3593 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3595 * Added new function silc_channel_payload_decrypt into the file
3596 lib/silccore/silcchannel.[ch].
3598 * Moved the channel message etc, check from silc_packet_decrypt
3599 to applications. The library calls now a generic
3600 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3601 when the packet is either normal or special. This was done to
3602 allow more wide range of checking that was not allowed when
3603 the code was in library. Now applications can do virtually any
3604 checks to the packet and return to the library the decision how
3605 the packet should be processed. Affected files are
3606 lib/silccore/silcpacket.[ch].
3608 Added silc_server_packet_decrypt_check to the server and
3609 silc_client_packet_decrypt_check to the client library.
3611 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3612 to send with specified source and destination information.
3614 * Channel message delivery between routers was broken after the
3615 channel key distribution was fixed earlier. The channel key
3616 was used be to distributed to other routers as well which is not
3617 allowed by the protocol. Now this is fixed and channel keys
3618 really are cell specific and the channel message delivery between
3619 routers comply with the protocol specification.
3621 * Fixed various commands in server to check also the global list
3622 for the channel entry and not just the local list. The affected
3623 file silcd/command.c.
3625 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3627 * Added assert()s to buffer formatting and unformatting routines
3628 to assert (if --enable-debug) when error occurs. Affected
3629 file: lib/silcutil/silcbuffmt.c.
3631 * Changed to auto-reconnect to check whether the remote host is
3632 router and register the re-connect timeout if it is. It used
3633 to check that whether we are normal server, but router must do
3634 auto-reconnect with another router as well. Affected file
3637 * Removed the [<key len>] option from CMODE command as the cipher
3638 name decides the key length, nowadays. See the defined ciphers
3639 from the protocol specification.
3641 * Added [<hmac>] option to the CMODE command to define the HMAC
3642 for the channel. Added SILC_CMODE_HMAC channel mode.
3644 * Added [<hmac>] option for the JOIN command so that user can
3645 select which HMAC is used to compute the MACs of the channel
3648 * Added Hmac field to the Channel Message Payload. The integrity
3649 of plaintext channel messages are now protected by computing
3650 MAC of the message and attaching the MAC to the payload. The
3651 MAC is encrypted. Now, it is clear that this causes some
3652 overhead to the size of the packet but rationale for this is that
3653 now the receiver can verify whether the channel message decrypted
3654 correctly and also when private keys are set for the channel the
3655 receiver can decrypt the packet with several keys and check from
3656 the MAC which key decrypted the message correctly.
3658 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3659 lib/silccrypt/silccipher.[ch].
3661 * Added silc_hash_len to return the digest length into the
3662 lib/silcrypt/silchash.[ch].
3664 * Rewrote parts of Silc Channel Payload interface in the
3665 lib/silccore/silcchannel.[ch]. The encode function now also
3666 encrypts the packet and parse function decrypts it.
3668 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Fixed a minor formatting bug in the SKE's key material processing.
3671 It actually might have processed the keys wrong way resulting
3674 * Redefined the mandatory HMAC algorithms and added new algorithms.
3675 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3676 and hmac-md5 truncated to 96 bits. The mandatory is now
3677 hmac-sha1-96. Rest are optional (including the one that used
3678 to be mandatory). Rationale for this is that the truncated HMAC
3679 length is sufficient from security point of view and can actually
3680 make the attack against the HMAC harder. Also, the truncated
3681 HMAC causes less overhead to the packets. See the RFC2104 for
3684 * Added new [hmac] configuration section. The SKE used to use
3685 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3686 is of course wrong. The official names that must be proposed in
3687 the SKE are the ones defined in the protocol specification
3688 (hmac-sha1-96 for example). The user can configure any hmac
3689 using any hash function configured in the [hash] section. At
3690 least, the mandatory must be configured.
3692 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3694 * Added HMAC list to the SKE proposal list. It has now both
3695 hash algorithm list and HMAC list. This makes the protocol
3696 incompatible with previous versions. The SKE now seems to work
3697 the way it is supposed to work, for the first time actually.
3699 * Defined plain Hash algorithms to the protocol specification.
3702 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Implemented support for key agreement packets into the server.
3705 Added functions silc_server_key_agreement and
3706 silc_server_send_key_agreement. Other than these functions,
3707 server has nothing to do with this packet.
3709 * Added support for private message key packets into the server.
3710 Added functions silc_server_private_message_key and
3711 silc_server_send_private_message_key.
3715 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3716 called in the protocol's final callback instead in the END
3717 protocol state. This makes a little more sense and in the same
3718 time in client we can use the same protocol routines for normal
3719 key exchange and to key agreement packet handling as well.
3721 * Added to both client's and server's KE protocol context the
3722 SilcSKEKeyMaterial pointer to save the key material. We will
3723 bring the key material to the protocol's final callback by doing
3724 this. The final callback must free the key material.
3726 * Added SKE's packet_send callback into client's KE protocol
3727 context so that the caller can choose what packet sending function
3728 is used. This way we can use different packet sending when
3729 doing normal SKE when doing key agreement packet handling (in
3730 the key agreement packet handling we do not want to encrypt
3733 * Implemented the responder side of the key agreement routines
3734 in the client. The client can now bind to specified port and
3735 accept incoming key negotiation. The key material is passed
3736 to the application after the protocol is over.
3738 * Implemented the processing of incoming Key Agreement packet
3739 in the client. Added function silc_client_key_agreement to
3742 * Implemented the intiator side of the key agreement routines
3743 in the client. The client can now initiate key agreement with
3744 another remote client. The key material is passed to the
3745 application after the protocol is over.
3747 * Created client_keyagr.c to include all the key agreement
3750 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3751 SILC_TASK_CALLBACK except that it is not static.
3753 * Created client_notify.c and moved the Notify packet handling
3754 from the client.[ch] into that file.
3756 * Created client_prvmsg.c and moved all private message and
3757 private message key routines from the client.[ch] into that file.
3759 * Create client_channel.c and moved all channel message and
3760 channel private key routines from the client.[ch] into that file.
3762 * Changed silc_client_get_client_by_id_resolve to resolve with
3763 WHOIS command instead of IDENTIFY command, in the file
3764 lib/silclient/idlist.c.
3766 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Implemented the SKE's responder side to the Client library.
3770 * When FAILURE is received to the protocol do not trust it
3771 blindly. Register a timeout to wait whether the remote closes
3772 the connection as it should do it, only after that process the
3773 actual failure. This was changed to both client and server.
3775 * Added client_internal.h to include some of the structures
3776 there instead of client.h in lib/silcclient/.
3778 * Added function silc_task_unregister_by_callback to unregister
3779 timeouts by the callback function.
3781 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Some "Incomplete WHOIS info" errors has been appearing on the
3784 log files. Took away the entry->userinfo check from WHOIS
3785 reply sending. The entry->userinfo is now " " if client did not
3786 provide one. I thought this was fixed earlier but something
3787 is wrong still. Let's see if the error still appears.
3789 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Fixed a minor bug in the login when the channel key is
3792 re-generated in the server. It used to generate the key in
3793 wrong order and thus caused problems in the channel traffic.
3795 * Fixed a minor bug in channel key distsribution after
3796 KICK command. The key was not sent to the router even though
3799 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Added silc_ske_process_key_material_data as generic routine
3802 to process any key material as the SILC protocol dictates. The
3803 function is used by the actual SKE library but can be used by
3804 applications as well. This relates to the private message keys
3805 and the channel private keys since they must be processed the
3806 same way the normal SILC session keys. The protocol dictates
3807 this. Affected files: lib/silcske/silcske.[ch].
3809 Added also silc_ske_free_key_material to free the
3810 SilcSKEKeyMaterial structure.
3812 * Defined silc_cipher_set_key function to set the key for
3813 cipher without using the object's method function. The affected
3814 files: lib/silccrypt/silccipher.[ch].
3816 * Implemented silc silc_client_add_private_message_key,
3817 silc_client_add_private_message_key_ske,
3818 silc_client_del_private_message_key,
3819 silc_client_list_private_message_keys and
3820 silc_client_free_private_message_keys functions in the
3823 Added functions silc_client_send_private_message_key to send
3824 the Private Message Key payload and silc_client_private_message_key
3825 to handle incoming Private Message Key payload.
3827 * Added Cipher field to the Private Message Key payload to set
3828 the cipher to be used. If ignored, the default cipher defined
3829 in the SILC protocol (aes-256-cbc) is used.
3831 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Removed lib/silcclient/ops.h file.
3835 Redefined parts of the SILC Client Library API. Created new
3836 file silcapi.h that deprecates the ops.h file and defines the
3837 published Client Library API. Defined also private message key
3838 API and channel private key API into the file.
3840 This is the file that the application must include from the
3841 SILC Client Library. Other files need not be included by
3842 the application anymore.
3844 * Added new key_agreement client operation callback and also
3845 defined the Key Agreement library API for the application.
3847 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3849 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3850 is used by clients to request key negotiation between another
3851 client in the SILC network. If the negotiation is started it
3852 is performed using the SKE protocol. The result of the
3853 negotiation, the secret key material, can be used for example
3854 as private message key.
3856 Implemented the Key Agreement payload into the files
3857 lib/silccore/silauth.[ch].
3859 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Redefined ciphers for the SILC protocol. Added some new ciphers
3862 and defined the key lengths for the algorithms. Changed the
3863 code accordingly. The default key length is now 256 bits.
3865 * Fixed SKE key distribution function silc_ske_process_key_material
3866 when the key length is more than 128 bits. The default key
3867 length in SILC is now 256 bits.
3869 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3870 to indicate unsupported algorithm.
3872 * Renamed rijndael.c to aes.c and all functions as well.
3874 * Fixed a long standing channel key setting bug in client library.
3875 Weird that it has never surfaced before.
3877 * Fixed bug in channel deletion. If the entire channel is removed
3878 then it must also delete the references of the channel entry
3879 from the client's channel list as the client's channel entry and
3880 the channel's client entry share same memory.
3882 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Implemented CONNECT and SHUTDOWN commands in the client.
3886 * Implemented CLOSE command to the client.
3888 * Added the function silc_idlist_find_server_by_name into the
3889 files silcd/idlist.[ch].
3891 Added the function silc_idlist_find_server_by_conn into the
3892 files silcd/idlist.[ch].
3894 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * DIE command was renamed to SHUTDOWN. Updated the both code
3899 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3900 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3902 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3905 * Added function silc_server_create_connection function to create
3906 connection to remote router. My server implementation actually
3907 does not allow router to connect to normal server (it expects
3908 that normal server always initiates the connection to the router)
3909 so the CONNECT command is only good for connecting to another
3912 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3915 or some other client was kicked from the channel.
3917 Implemented the handling of the notify type to both client
3920 Implemented silc_server_send_notify_kicked to send the KICKED
3921 notify. It is used to send it to the server's primary router.
3923 * Implemented the KICK command into server and client.
3925 * Added `query' argument to the silc_idlist_get_client function
3926 to indicate whether to query the client from server or not if
3929 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3930 to indicate that the client is not channel founder.
3934 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3936 * Removed the rng context from SilcPacketContext structure and
3937 changed that the packet routine uses the Global RNG API.
3939 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Added support for quit message that client can "leave" on the
3942 channel when it quits the SILC. It is ditributed inside the
3943 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3945 Added silc_server_free_client_data that will take the
3946 signoff message as argument.
3948 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3950 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Updated parts of the protocol specification to keep it up
3955 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3958 payloads in one packet.
3960 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3961 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3962 use now the new List flag.
3964 * Also deprecated the following packet types: REPLACE_ID,
3965 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3967 * Added list support for Notify packet in server.
3969 * Added silc_server_send_notify_channel_change to send the
3970 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3971 the silc_server_send_replace_id.
3973 * Added silc_server_send_notify_nick_change to send the
3974 NICK_CHANGE notify type. Deprecates the function
3975 silc_server_send_replace_id.
3977 * Added silc_server_send_notify_join to send the JOIN notify type.
3978 Deprecates the function silc_server_send_new_channel_user.
3980 * Added silc_server_send_notify_leave to send LEAVE notify type.
3981 Deprecates the function silc_server_send_remove_channel_user.
3983 * Added silc_server_send_notify_cmode and
3984 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3985 types. Deprecates the silc_server_send_set_mode function.
3987 * Added SERVER_SIGNOFF notify type to indicate that server has
3988 quit. This means that all clients on the channel from that
3989 server will drop. This can be also used when netsplit happens.
3991 Deprecated REMOVE_ID packet type since it is not needed anymore
3994 Added silc_server_send_notify_server_signoff to send the
3995 SERVER_SIGNOFF notify type. Deprecates the function
3996 silc_server_send_remove_id.
3998 Added also silc_server_send_notify_signoff to send the
3999 SIGNOFF notify type.
4001 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4002 SILC protocol from this day on. Changed the protocol
4003 specification as well.
4005 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4006 notify type. It is used between routers to notify about
4007 topic changes on a channel.
4009 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4012 * Partly updated the protocol specification to comply with the
4013 changes now made. It is still though a bit outdated.
4015 * The JOIN notify type now takes one extra argument <Channel ID>.
4016 The packet used to be destined to the channel but now the
4017 JOIN type may be sent as list thus it is impossible to
4018 destine it to any specific channel. By adding this argument
4019 it is again possible.
4021 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Added CREDITS file. The CHANGES and CREDITS file will appear
4024 in the distribution as well.
4026 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4029 types in the server's silcd/packet_receive.c.
4031 * Implemented CMODE and CUMODE to work in router environment.
4033 * Fixed minor encoding and decoding buglet from the
4034 lib/silccore/silcmode.c.
4036 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4039 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4041 * Changed all SilcConfigServer* and silc_config_server* to
4042 SilcServerConfig* and silc_server_config*, respectively.
4045 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Associated the ID (client or server ID) to the Authentication
4048 Payload to avoid any possibility of forging. Updated the
4049 protocol specification and the code accordingly.
4051 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * The RSA key length is now save to the RsaKey context in the
4054 key generation process in lib/silccrypt/rsa.c. The key length
4055 is now used to figure out the maximum size of the block allowed
4056 to be encrypted/signed.
4058 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4059 is equivalent to the silc_mp_mp2bin but does not allocate any
4062 * Changed silc_mp_mp2bin API to take length argument. If it is
4063 non-zero then the buffer is allocated that large. If zero, then
4064 the size is approximated using silc_mp_sizeinbase, which however
4067 * Created Global RNG API which is global RNG that application can
4068 initialize. After initializing, any routine anywhere in the
4069 code (including library) can use RNG without allocating a new
4070 RNG object. This was done to allow this sort of use of the
4071 RNG in code that has no chance to allocate RNG object. All
4072 applications currently allocate this and many routines in the
4073 library use this. Affected file lib/silccrypt/silcrng.[ch].
4075 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4076 it to use the Global RNG API.
4078 * Defined Authentication Payload into protocol specification that
4079 is used during SILC session to authenticate entities. It is
4080 used for example by client to authenticate itself to the server
4081 to obtain server operator privileges.
4083 Implemented this payload into the lib/silccore/silcauth.[ch].
4084 Implemented also routines for public key based authentication
4085 as the new protocol specification dictates.
4087 Moved definitions of different authentication methods from
4088 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4090 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4091 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4092 silc_pkcs_verify_with_hash functions into the file
4093 lib/silccrypt/silcpkcs.[ch].
4095 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * The client entry's userinfo pointer must be always valid.
4098 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4099 will fail since it requires the userinfo. Now, the userinfo
4100 is allocated as "" if actual userinfo does not exist. Actually,
4101 it must exist and it is totally Ok to drop client connections
4102 that does not announce the userinfo. However, we will make
4103 this workaround for now.
4105 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4106 to return the remote port by socket.
4108 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4111 SILC_SERVER_PENDING_EXEC and added an new macro
4112 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4113 data or when error occurs while processing the pending command.
4115 Added new argument `destructor' into silc_server_command_pending
4116 and to the SilcServerCommandPending object. This destructor is
4117 now called after calling the pending callback or if error occurs
4118 immediately. If error occurs the actual pending callback won't
4119 be called at all - only the destructor. The destructor may be
4120 NULL if destructor is not needed.
4122 All this applies for client library code as well. Similar
4123 changes were made there as well for the pending commands.
4125 In the client, the application must now allocate the
4126 SilcClientCommandContext with the silc_client_command_alloc
4129 * Added reference counter to the SilcServerCommandContext. Added
4130 function silc_server_command_alloc and silc_server_command_dup
4133 Same type of functions added to the client library for the same
4136 * Removed the cmd_ident from IDListData away since it is now
4137 global for all connections. It is the command identifier used
4138 in command sending and with pending commands. The affected file
4141 * Added reference counter to the SilcSocketConnection objecet to
4142 indicate the usage count of the object. The object won't be
4143 freed untill the reference counter hits zero. Currently only
4144 server uses this, and client ignores it. The client must be
4145 set to use this too later. The affected files are
4146 lib/silccore/silcsockconn.[ch]. Added also the function
4147 silc_socket_dup to increase the reference counter.
4149 This was mainly added because it is possible that the socket
4150 is removed underneath of pending command or other async
4151 operation. Now it won't be free'd and proper DISCONNECTING
4152 flags, etc. can be set to avoid sending data to connection that
4153 is not valid anymore.
4155 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4156 the connection. After that it sets SILC_SET_DISCONNECTED.
4157 It is, however, possible that the socket data is not still freed.
4158 The silc_server_packet_process now checks that data is not
4159 read or written to connection that is DISCONNECTED. The socket
4160 get's freed when the reference counter hits zero.
4162 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Changed the client operation API: channel_message operation's
4165 `sender' is now the client entry of the sender, not the nickname
4166 and the `channel' is the channel entry, not the channel name.
4168 In the private_message operation the `sender' is now also the
4169 client entry of the sender not the nickname.
4171 Affected file is lib/silcclient/ops.h and all applications
4172 using the client operations.
4174 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Moved the calling of ops->connect() from connect_to_server_final
4177 into receive_new_id functin since that is the point when the
4178 client is actually allowed to send traffic to network. The
4179 affected file is lib/silcclient/client.c.
4181 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4184 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4185 (if needs broadcasting) instead of broadcasting the packets one
4186 by one which would make a burst in the network traffic.
4188 * Added `broadcast' argument to the functions in silcd/server.[ch]
4189 silc_server_create_new_channel[_with_id] to indicate whether
4190 to send New Channel packet to primary router.
4192 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Added new function into the silcd/server.[ch] files:
4195 silc_server_create_new_channel_with_id to create new channel with
4196 already existing Channel ID.
4198 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4199 lib/silccore/silcpacket.h. This packet is used t send list of
4200 Set Mode payloads inside one packet. Server uses this to set
4201 the modes for the channels and clients on those channels, that it
4202 announced to the router when it connected to it. The protocol
4203 specification has been updated accordingly.
4205 * The silc_server_new_channel did not handle the packet coming
4206 from normal server as it normally does not send that. However,
4207 when it announces its channels it does send it. Implemented
4208 the support for that.
4210 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4211 into the file lib/silccore/id.h.
4213 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Fixed memory leaks in the functions silc_idlist_del_client,
4216 silc_idlist_del_channel and silc_idlist_del_server in the file
4217 silcd/idlist.c. All of those leaked like a sieve.
4219 * Fixed some small memory leaks in the client's function
4220 silc_client_notify_by_server.
4222 * Added functions into silcd/server.c: silc_server_announce_clients,
4223 silc_server_announce_channels and silc_server_announce_server.
4224 These functions are used by normal and router server to announce
4225 to its primary router about clients, channels and servers (when
4226 router) that we own. This is done after we've connected to the
4229 These functions effectively implements the following packet types:
4230 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4231 and SILC_PACKET_NEW_ID_LIST.
4233 * Added new functions into the silcd/packet_receive.[ch]:
4234 silc_server_new_id_list, silc_server_new_channel_list and
4235 silc_server_new_channel_user_list to handle the incoming
4236 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4238 * Added support of changing Channel ID in the function
4239 silc_server_replace_id. If the server that announces a channel
4240 to the router already exists in the router (with same name but
4241 with different Channel ID), router is responsible to send
4242 Replace ID packet to the server and force the server to change
4243 the Channel ID to the one router has.
4245 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4246 client that the Channel ID has been changed by the router. The
4247 normal server sends this to the client. Client must start using
4248 the new Channel ID as the channel's ID.
4250 Implemented handling of this new type into lib/silcclient/client.c
4251 into the function silc_client_notify_by_server.
4253 * Added new function silc_idlist_replace_channel_id into the files
4254 silcd/idlist.[ch] to replace the Channel ID.
4256 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Call silc_server_command_identify_check always when processing
4259 the IDENTIFY command in silcd/command.c
4261 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4264 send keepalive packets. The packet can be sent by clients,
4265 servers and routers.
4267 Added function silc_socket_set_heartbeat into the file
4268 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4269 If not set, the heartbeat is not performed. The actual
4270 heartbeat is implemented in the low level socket connection
4271 library. However, application is responsible of actually
4274 Added silc_server_send_heartbeat to send the actual heartbeat
4275 packet into silcd/packet_send.[ch]. Server now performs
4276 keepalive with all connections.
4278 * Added silc_task_get_first function into lib/silcutil/silctask.c
4279 to return the timeout task with shortest timeout. There was a bug
4280 in task unregistration that caused problems. TODO has been
4281 updated to include that task system must be rewritten.
4283 * The client library will now resolve the client information when
4284 receiving JOIN notify from server for client that we know but
4285 have incomplete information.
4287 * Rewrote parts of silc_server_remove_from_channels and
4288 silc_server_remove_from_one_channel as they did not remove the
4289 channel in some circumstances even though they should've.
4291 * Encryption problem encountered in server:
4293 The LEAVE command used to send the Channel Key packet to the
4294 router immediately after generating it. However, the code
4295 had earlier sent Remove Channel user packet but not immediately,
4296 ie. it was put to queue. The order of packets in the router
4297 was that Channel Key packet was first and Remove Channel User
4298 packet was second, even though they were encrypted in the
4299 reverse order. For this reason, MAC check failed. Now, this
4300 is fixed by not sending the Channel Key packet immediately but
4301 putting it to queue. However, this is more fundamental problem:
4302 packets that are in queue should actually not be encrypted
4303 because packets that are sent immediately gets encrypted
4304 actually with wrong IV (and thus MAC check fails). So, packets
4305 that are in queue should be encrypted when they are sent to
4306 the wire and not when they put to the queue.
4308 However, the problem is that the current system has not been
4309 designed to work that way. Instead, the packet is encrypted
4310 as soon as possible and left to the queue. The queue is then
4311 just purged into wire. There won't be any fixes for this
4312 any time soon. So, the current semantic for packet sending
4315 o If you send packet to remote host and do not force the send
4316 (the packet will be in queue) then all subsequent packets to the
4317 same remote host must also be put to the queue. Only after the
4318 queue has been purged is it safe again to force the packet
4321 o If you send all packets immediately then it safe to send
4322 any of subsequent packets through the queue, however, after
4323 the first packet is put to queue then any subsequent packets
4324 must also be put to the queue.
4326 Follow these rules and everything works fine.
4328 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added new function silc_server_remove_clients_by_server to
4331 remove all client entries from ID list when the server connection
4332 is lost. In this case it is also important to invalidate all
4333 client entires as they hold the invalid server entry. This
4334 fixes fatal bug when server has lost connection and will reconnect
4337 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Made some sanity checks to silc_server_daemonise like to check
4340 whether the requested user and group actually exists.
4342 * Added sanity check to SKE's silc_ske_responder_finish to check
4343 that the public and private key actually is valid.
4345 * Invalidate the client's nickname when receiving Replace ID
4346 packet and the Client ID is being replaced. This means that the
4347 server will query the nickname if someone needs it (client)
4350 * Sort the ID Cache in client library when the ID Cache data
4351 has changed (needs sorting).
4353 * Do not allow for SILC client to create several connections to
4354 several servers. The client does not support windows right now
4355 and generating multiple connections causes weird behaviour.
4357 Irssi-silc client does support windows and can handle several
4358 connections without problems, see: www.irssi.org and SILC plugin.
4360 * Fixed some places where client was added to the IDList. The
4361 rule of thumb is following (in order to get everything right):
4362 If the client is directly connected local client then the
4363 `connection' argument must be set and `router' argument must be
4364 NULL to silc_idlist_add_client function. If the client is not
4365 directly connected client then the `router' argument must
4366 bet set and the `connection' argument must be NULL to the
4367 silc_idlist_add_client function.
4369 * The funtion silc_server_packet_send_local_channel actually did
4370 not check whether the client was locally connected or not. It
4371 does that now. Fixed a bug related to LEAVE command.
4373 * Fixed Remove Channel User payload parsing bug in server's
4374 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4376 * The server's silc_server_save_channel_key now checks also the
4377 global ID list for the channel as it might not be in the local
4378 list. Fixed a bug related to LEAVE command.
4380 * Is this the end of the [<unknown>] buglet that has been lurking
4381 around for a long time? A little for loop fix in server's
4382 silc_server_command_whois_parse that is used by both IDENTIFY
4383 and WHOIS command. At least, this was a clear bug and a cause
4384 of one type of [<unknown>] buglet.
4386 * WHOIS and IDENTIFY commands call the function
4387 silc_server_command_[whois/identify]_check function even if
4388 we are not router server.
4390 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Added --with-gmp configuration option. If set the GMP
4393 is always compiled in the SILC source tree. If not set then
4394 it is checked whether the system has the GMP3 installed. If
4395 it has then the GMP won't be compiled (the system's headers
4396 and library is used), if it doesn't have it then the GMP is
4397 compiled in the SILC source tree.
4399 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Changed RSA private exponent generation to what PKCS #1
4402 suggests. We try to find the smallest possible d by doing
4403 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4404 not security fix but optimization.
4406 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Added new config entry [Identity] to fork the server and run
4409 it as specific user and group. A patch from Bostik.
4411 * Imported Dotconf configuration library into lib/dotconf.
4412 This will be used to create the SILC configuration files later.
4413 It will appear in the distsribution after this commit.
4415 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * A big code auditing weekend happening. Auditing code for
4418 obvious mistakes, bugs and errors. Also, removing any code
4421 Removed files for being obsolete:
4423 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4424 inline in the file lib/silcutil/silcbuffer.h)
4426 o lib/silcutil/silcbufutil.c (the header has inline versions)
4428 Changed code to fix possible error conditions:
4430 o The buffer formatting routines now check that the destination
4431 buffer really has enough space to add the data. This applies for
4432 both buffer formatting and unformatting
4433 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4434 unformatting was changed to accomodate following rules:
4435 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4436 sent to the function while XXX_*STRING will not allocate or copy
4437 the data into the buffer. Instead it sets the pointer from the
4438 buffer into the pointer sent as argument (XXX_*STRING used to
4439 require that the pointer must be allocated already). This change
4440 makes this whole thing a bit more consistent and more optimized
4441 (note that the data returned in the unformatting with XXX_*STRING
4442 must not be freed now). The routines return now -1 on error.
4444 o Tried to find all code that use buffer_format and buffer_unformat
4445 and added return value checking to prevent formatting and
4446 especially unformatting errors and possible subsequent fatal
4449 o Changed ske->x and ske->KEY to mallocated pointers in
4450 lib/silcske/silcske.h. Fixed possible data and memory leak.
4452 o Added return value checking to all *_parse* functions. Fixed
4453 many memory leaks as well.
4455 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4456 so that buffer overflows would not happen. All code now also
4457 checks the return value as it can fail.
4459 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Added reconnection support to server if the normal server looses
4462 its connection to the router (for example if router is rebooted).
4463 The server performs normal reconnection strategy implemented
4464 to the server. Affected file silcd/server.c.
4466 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Added new packet type SILC_PACKET_SET_MODE that is used to
4469 distribute the information about changed modes (for clients,
4470 channels and clients channel modes) to all routers in the
4471 network. Updated the protocol specification accordingly.
4473 Added functions into silcd/packet_send.c and
4474 silcd/packet_receive.c: silc_server_send_set_mode,
4475 silc_server_set_mode.
4477 Added new files silcmode.[ch] into lib/silccore that implements
4478 the encoding and decoding of Set Mode Payload. Added new type
4479 SilcSetModePayload. Moved the definitions of different modes
4480 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4482 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Oops, a little mistake in server's connection authentication
4485 protocol. The protocol is not ended with FAILURE but with
4486 SUCCESS if the authentication is Ok. :) Affected file is
4489 * Implemented NICK_CHANGE notify handling in server in the file
4490 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4491 the local clients on the channel. After the changing nickname
4492 in router environment snhould work and the [<unknown>] nickname
4493 should appear no more.
4495 The silc_server_replace_id function that receives the Replace ID
4496 payload now sends the NICK_CHANGE notify type also in the file
4497 silcd/packet_receive.c
4499 * Changed WHOIS and IDENTIFY command to support the maximum amount
4500 of arguments defined in protocol specs (3328 arguments). This
4501 fixed a bug that caused problems when there were more than three
4504 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Added extra parameter, command identifier, to the
4507 silc_client_send_command so that explicit command identifier
4510 Changed that ID list routines uses specific command identifier
4511 when sending WHOIS/IDENTIFY requests to the server so that they
4512 can be identified when the reply comes back.
4514 Affected files lib/silcclient/command.[ch],
4515 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4517 * Added `sender' argument to silc_server_packet_send_to_channel
4518 to indicaet the sender who originally sent the packet to us
4519 that we are now re-sending. Ignored if NULL. Affected file
4520 silcd/packet_send.[ch].
4522 * Added some server statistics support in silcd/server_internal.h
4523 SilcServerStatistics structure and around the server code. Also
4524 send some nice statistics information when client is connecting
4527 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Fixed channel ID decoding in server's JOIN command reply in
4530 silcd/command_reply.c
4532 * Fixed braodcasting of replace ID payload to not to send it if
4533 we are standalone server in silcd/packet_receive.c.
4535 * Fixed all channel message sending routines to not to send
4536 packets to clients that has router set, since they are routed
4537 separately in the same function earlier. Affects file
4538 silcd/packet_send.c and all channel packet sending functions.
4540 * In USERS reply, res_argv[i] are not allocated, the table
4541 is allocated. Thus changed that free the table, not its
4544 * In server's whois_check and identify_check if the client is
4545 locally connected do not send any WHOIS commands - they are not
4548 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Fixed some minor bugs in client when sending WHOIS command. The
4551 arguments was in wrong order.
4553 * Removed statis function add_to_channel from server in
4554 silcd/command.c that was previously used with the joining but
4557 * Tested USERS command in router environment successfully with two
4558 routers, two servers and two clients.
4560 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Reorganized the USERS command and command reply in client library
4563 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4564 When the command is given by user we register a pending command
4565 callback that will reprocess the command after the reply has been
4566 received from the server. When reprocessing the packet we then
4567 display the information. Thus, the USERS information is displayed
4568 now in the command callback instead of in the command reply
4569 callback. The processing of the command is same as previously
4570 when server has sent the command reply in the JOINing process.
4572 * Added to USERS command in silcd/command_reply.c to join the client,
4573 we didn't use to know about, to the channel after we've created
4574 a client entry for it. Also, for clienet we did know already still
4575 check whether it is on the channel or not and add it if not.
4577 * Removed silc_server_command_join_notify as the function and its
4580 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Changed the client's pending command handling to the same as the
4583 server's pending command handling. It is also now possible to
4584 execute command reply functions from other command reply
4585 function as the function callbacks for commands and command
4586 replies are one and same. The pending commands are not static
4587 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4588 in client connection context. Thus, pending commands are server
4589 connection specific as it is convenient.
4591 Changed the function silc_client_command_pending and
4592 silc_client_command_pending_del and added new function
4593 silc_client_command_pending_check. Removed the
4594 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4597 * Added cmd_ident, current command identifier, to the client
4598 connection context in lib/silcclient/client.h to keep track on
4599 command identifiers used in command sending. Client's command reply
4600 function handling now supports the mandatory command identifiers.
4602 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4603 funtions in client to fully support pending command callbacks.
4605 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4606 as one of the arguments to the application in the command reply
4609 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4610 before first releasing SILC but came back. Now it is removed again
4611 and should come back nomore. The FORWARDED flag was used only
4612 by the JOINing procedure by forwarding the command packet to router.
4613 Now, the JOINing procedure has been changed to more generic (due
4614 to various router environment issues) and FORWARDED is not needed
4615 anymore for anything. The protocol specification is yet to be
4618 Now, removed silc_server_packet_forward from server and the flag
4619 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4621 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Renamed NAMES command to USERS command. The NAMES was named that
4624 due to historical reasons. Now it is renamed. Also, rewrote
4625 parts of the USERS command. The nickname list is not sent anymore
4626 by the server. Only Client ID and mode lists are sent in the USERS
4627 command. Changed this also to the protocol specification.
4629 The client now resolves the names and stuff after it receives
4630 the USERS list from the server when joining to the channel.
4632 * WHOIS and IDENTIFY commands has been changed to support multiple
4633 Client ID's per command. One can now search for multiple users
4634 in the network by sending only one WHOIS or IDENTIFY command.
4635 Changed the code and the protocol specifications.
4637 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4638 uses silc_server_command_whois_parse to parse the request. */
4640 * If normal server, do not parse the WHOIS and IDENTIFY requests
4641 before sending it to the router. Saves some time.
4643 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Fixed JOIN command on client library. Wrong number of arguments
4646 used to crash the client.
4648 * Added silc_server_channel_has_global function to check whether
4649 channel has global users or not.
4651 * Added silc_server_channel_has_local function to check whether channel
4652 has locally connected clients on the channel.
4654 * The silc_server_remove_from_one_channel now checks whether the
4655 channel has global users or not after given client was removed from
4656 the channel. It also checks whether the channel has local clients
4657 on the channel anymore. If it does not have then the channel entry
4658 is removed as it is not needed anymore.
4660 * The silc_server_notify now checks on JOIN notify whether the joining
4661 client is one of locally connected or global. If it is global then
4662 the channel has now global users on the channel and that is marked
4663 to the channel entry. Also, it now saves the global client to
4664 global list who is joining and JOINs it to the channel. This is
4665 for normal server, that is.
4667 Changed silc_server_send_notify_on_channel,
4668 silc_server_packet_relay_to_channel and
4669 silc_server_packet_send_to_channel check if we are normal server
4670 and client has router set (ie. global client) do not send the
4671 message to that client, as it is already routed to our router.
4673 * Implemented LEAVE notify type handling in silc_server_notify
4676 * Tested LEAVE command in router environment successfully. Tested
4677 with two routers, two servers and two clients.
4681 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4683 * Implemented SIGNOFF notify type handling in silc_server_notify
4686 * silc_server_remove_id now removes the client entry from all channels
4687 it has joined and thusly sends SIGNOFF notify type.
4689 * Rewrote the NAMES list generation in server by removing two excess
4690 loops. The lists are created now inside one loop.
4692 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4694 * silc_server_remove_channel_user checks now also global list
4695 for channel and client.
4697 * silc_server_new_channel_user checks now both local and global
4698 list for channel and client. Fixed a bug in client id decoding.
4699 Used to decode wrong buffer.
4701 * silc_server_channel_message checks now both local and global
4702 list for channel entry.
4704 * Tested channel joining (hence JOIN) in router environment
4705 successfully. Tested with two routers, two servers and two
4708 * Tested channel message sending in router environment successfully.
4710 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added silc_server_save_channel_key into server.[ch] to save the
4713 received channel key in Channel Key payload processing. It is
4714 also used in JOIN command reply handling.
4716 Equivalent function silc_client_save_channel_key added into
4717 client.[ch] into client library.
4719 * Changed JOIN command reply to send information whether the channel
4720 was created or not (is existing already) and the channel key
4721 payload. Changed protocol specs accordingly.
4723 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4724 the request was sent by ID and not by nickname. Crashed on
4727 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4730 now correctly save the received data.
4732 * silc_server_free_sock_user_data now notifies routers in the
4733 network about entities leaving the network.
4735 At the same time implemented functions silc_server_remove_id
4736 and silc_server_send_remove_id to receive and send REMOVE_ID
4737 packets. The packet is used to notify routers in the network
4738 about leaving entities. The ID removed will become invalid in
4741 * Added function silc_idlist_del_server into server. Removes and
4742 free's server entry from ID list.
4744 * silc_server_private_message function now checks, if we are router,
4745 that the destination ID really is valid ID, naturally.
4747 * In router when NEW_ID packet is received (for new client) the
4748 hash of the Client ID is saved in the ID Cache but the
4749 client->nickname is set to NULL, instead of putting the hash
4752 IDENTIFY command now also checks that client->nickname must be
4753 valid. If it is not if will request the data from the server who
4754 owns the client. Added new function
4755 silc_server_command_identify_check.
4757 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4758 to set the command to already allocated Command Payload.
4760 * Tested private message sending in router environment with two
4761 routers, two servers and two clients. Fixed minor bugs and now
4764 * Fixed segfault from client's NAMES command. Used to crash if
4767 * Forwarded packets must not be routed even if it is not destined
4768 to the receiver. Changed server code comply with this.
4770 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Added `require_reverse_mapping' boolean value to ServerParams
4773 structure. If TRUE (not default) the server will require that
4774 the connecting host has fully qualified domain name.
4776 If the reverse mapping is not required and hostname could not be
4777 found the IP address is used as hostname.
4779 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Implemented version string checking to both client and server.
4782 The check is incomplete currently due to the abnormal version
4783 strings used in development version of SILC.
4785 * Changed all command functions in server to use the new
4788 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Changed char *data to unsigned char *data in ID Cache system to
4791 support binary data as ID Cache data. Changed code to support
4792 binary data in lib/silccore/idcache.c.
4794 * Renamed silc_server_packet_relay_command_reply to
4795 silc_server_command_reply as it is normal packet receiving
4796 function. Rewrote the function to accept command replys for
4797 servers and not only for clients.
4799 * Mark remote router always as registered server if we are connecting
4800 to it. Otherwise, commands sent by the router to us are ignored.
4802 * All ID List find routines now returns the ID Cache Entry pointer
4803 as well if requested.
4805 * WHOIS command works now in router environment, tested with two
4806 routers, two servers and two clients.
4808 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4809 in router environment (as it is almost equivalent to WHOIS) but
4810 hasn't been tested thoroughly. Added new functions:
4812 silc_server_command_identify_parse
4813 silc_server_command_identify_send_reply
4814 silc_server_command_identify_from_client
4815 silc_server_command_identify_from_server
4817 * Disabled route cache adding because adding two different ID's with
4818 same IP replaces the old cache entry thus giving wrong route.
4819 The entry->router->connection is always the fastest route anyway
4820 so route cache may not be needed. Of course, new routes maybe
4821 established after receiving the ID when the entry->router->connection
4822 might not be anymore the most optimal.
4824 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Add route cache for received ID for fast routing.
4828 * Added silc_server_packet_route to route received packet on router
4829 that is not destined to us.
4831 * Renamed silc_server_get_route to silc_server_route_get.
4833 * Added id_string and id_string_len fields into SilcServer to
4834 include encoded ServerID for fast comparing without excess
4835 encoding of the ID's.
4837 * Cleaned up WHOIS command on server side. Added following static
4840 silc_server_command_whois_parse
4841 silc_server_command_whois_check
4842 silc_server_command_whois_send_reply
4843 silc_server_command_whois_from_client
4844 silc_server_command_whois_from_server
4846 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4847 arguments in command replies. All command functions should be
4848 updated to use this macro.
4850 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Minor typo fixes on command reply handling on server.
4854 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Added silc_server_command_add_to_channel internal routine to add
4857 the client to the channel after router has created the channel and
4858 sent command reply to the server.
4860 * Added generic silc_server_send_command to send any command from
4863 * Use static buffer with ID rendering instead of duplicating data.
4865 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Fixed a channel user mode bug when joining to a channel server gave
4868 everybody channel founder rights, oops.
4870 * We mark ourselves as the router of the incoming server connection
4871 if we are router ourselves. This way we can check in some packet
4872 sending functions whether it is locally connected server. For
4873 incoming router connections we put NULL.
4875 * For router sending packets locally means now always sending the
4876 packet cell wide; to local clients and local servers. For normal
4877 server sending packet locally means sending it to only local
4880 * Fixed the JOIN command to really work in router environment. If the
4881 channel is created it is always created by the router. Router is
4882 also responsible of making the initial joining to the channel,
4883 sending JOIN notify to the sending server and distributing
4884 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4885 does not exist server doesn't do anything else but forward the
4886 command to the router which performs everything.
4888 * Added silc_server_send_channel_key function to send the Channel Key
4891 * Added silc_server_create_channel_key to create new channel key. The
4892 channel key is now re-generated everytime someone joins or leaves
4893 a channel, as protocol dictates. Note: channel->key_len is the
4896 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4899 packet_receive.[ch] to separate packet sending and receiving
4900 routines. The server.[ch] now includes everything else including
4901 actual packet processing (writing and reading data) and other
4904 Renamed silc_server_private_message_send_internal to
4905 silc_server_send_private_message. The routine is still though
4906 used only to relay private messages as server does not send
4907 private messages itself.
4909 Renamed silc_server_new_channel to silc_server_create_new_channel
4910 and added new function sicl_server_new_channel that handles the
4911 incoming New Channel packet. Added also new sending function
4912 silc_server_send_new_channel to send New Channel Payload.
4914 * Added new function silc_server_notify to process incoming notify
4915 packet to the server/router. Server may then relay the notify
4916 to clients if needed.
4918 * Added new function silc_server_new_channel_user to process incoming
4919 New Channel User packet. Router will redistribute the packet and
4920 send JOIN notify to its local clients and locally connected servers
4921 if needed. Normal server will send JOIN notify to its local client
4922 on same channel when received this packet. Added also corresponding
4923 sending function silc_server_send_new_channel_user to sent the
4926 * Added boolean route argument to send_notif_to_channel and
4927 packet_send_to_channel functions to attempt to route the packet
4928 if it is TRUE and send only locally if it is FALSE.
4930 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * silc_server_replace_id now broadcasts the received replace ID
4933 packet if it is not broadcast packet already. The router must
4934 broadcast to inform other routers about changed ID.
4936 * Added backpointer to server's router into SilcServer context in
4937 silcd/server_internal.h.
4939 * Fixed silc_server_packet_broadcast to send correct broadcast
4942 * The channel key is now distributed to the local client as soon
4943 as it is received from the router (in router environment) so that
4944 no other packet may be sent for the channel until client has
4947 * silc_server_remove_channel_user now broadcasts the received
4948 Remove Channel User packet if it is not broadcast packet already.
4949 The router must broadcast to inform other routers about removed
4952 * Added users field into SilcPacketContext that is a reference count
4953 of the context. One can increase the reference count by calling
4954 silc_packet_context_dup which is now changed to just increase the
4955 reference count instead of duplicating the data. The reference
4956 count is decresed by calling silc_packet_context_free that will
4957 free the data after the reference count hits zero.
4959 For now on the packet context and everything allocated into it
4960 (including the raw packet from network) must be freed by calling
4961 the new silc_packet_context_free function. Added also new function
4962 silc_packet_context_alloc that must be used now to allocate the
4963 context. This also means that if a routine is asynchronous from
4964 silc_[client/server]_packet_parse_type the packet context must
4965 be duplicated by calling silc_packet_context_dup. Otherwise it
4966 gets free'd after silc_[client/server]_packet_parse_type returns.
4967 Also, one must remember that if packet is duplicated then its
4968 reference count must be decresed by calling the free function as
4969 many times as it was duplicated.
4971 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4972 from both client and server.
4974 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Made joining to a channel working in router environment.
4978 * Cleaned up JOIN command on server side and create function
4979 silc_server_command_join_channel internal routine to make the
4982 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Changed silc_command_pending list to SilcDList. Also, added
4985 `ident' field to SilcServerCommandPending structure to identify
4986 the reply and to call correct callback.
4988 Added silc_server_command_pending_check function to replace the
4989 corresnponding macro. The silc_command_pending list is not
4992 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4993 to set identifier to previously allocated Command Payload. It
4994 is used to set identifier for command when resending Command
4997 * Added silc_command_payload_encode_payload to encode Command
4998 Payload buffer from SilcCommandPayload structure.
5000 * Added silc_argument_payload_encode_payload to encode Argument
5001 payload buffer from SilcArgumentPayload structure.
5003 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Changed WHOIS command to support router connection on server side.
5006 The whois request is always sent to router unless the server is
5007 standalone server. After server has received the reply from the
5008 router will it send the reply to the client.
5010 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5011 broadcast received broadcast packet. The function is used only
5012 by router. The broadcast packet is always sent to the router's
5015 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5016 render given ID to printable string, for log files for example.
5018 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Made basic router to router connections working. At least they
5021 can now connect to each other but nothing really works the way
5022 they are supposed - yet.
5024 * Added new initiator token to RouterConnection configuration
5025 file in silcd/serverconfig.[ch]. It is used to tell whether we
5026 are the initiator to the remote router or whether we'll expect
5027 the other end to connect.
5029 * Moved registering of listener task to silc_server_init, hence
5030 the server starts listenning as soon as it is run, even if it
5031 does not have connections to other routers. Let's see how well
5034 * Changed default connection retry timeouts for more suitable in
5037 * Removed cipher and such arguments from silc_idlist_add_client
5038 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5039 Added new function silc_idlist_add_data to add the keys and stuff
5042 * Added SilcIDListData structure and added it to SilcClientEntry
5043 and SilcServerEntry as their first field in the structure. This
5044 way we can explicitly cast the ID entries to the SilcIDListData
5045 structure and get common data for the entries. In past, we had
5046 to first check what type of connection it is and then cast it to
5047 correct ID entry type. Now, we can directly cast the opaque
5048 pointer to the SilcIDListData (no matter what ID entry it actually
5049 is) and get the data needed.
5051 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5054 in some circumstances even if threre were timeout tasks, though not
5055 IO tasks, but tasks anyway. Now fixed.
5057 * Defined SilcServerConnection structure to hold connection specific
5058 stuff about directly connected servers and routers. The definition
5059 is currently in silcd/server_internal.h. I thought about having
5060 a bit more important role fro this struct but for now it is used
5061 only when connecting to other server (or router actually).
5063 * Added connecting retry support in server when connecting to
5064 router(s). The retry feature implement exponential backoff
5065 algorithm. Also, added SilcServerParams structure to hold default
5066 parameters for server. For now, it include these retry settings
5067 and are hard coded. After server is moded to be as Silc Server
5068 Library this structure will be more important.
5070 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Changed client librarys channel->clients table to SilcList and
5073 changed code accordingly.
5075 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Changed client's channel table to SilcList and changed code
5078 accordingly. Also changed SilcChannelClientEntry to include back-
5079 pointer to the channel so that client entry can use that structure
5080 as list as well and we have fast cross-reference to the channel.
5081 This change dramatically decreased the complexity of channel
5082 handling with client entry and vice versa (removed one extra
5083 loop when searching for channel entry from many functions).
5085 * Changed server->sim from table to SilcDList and changed code
5088 * NAMES command can now be used from user interface. It will show
5089 the user list on the channel, neatly.
5091 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5092 Code now saves realname of the user if it becomes available.
5094 * Renamed configure.in to configure.in.pre and made ./prepare
5095 script to automatically add correct version string to
5096 configure.in which it creates from configure.in.pre.
5098 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * NAMES command reply now shows users mode with the nickname when
5103 * Moved silc_client_ch[u]mode[_char] functions from
5104 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5105 place sucks, they are utility functions and should be in some
5108 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5110 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5113 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Added TRQ (efficient deque and list library) into lib/trq. This is
5118 a very good list library that is currently used in the SILC. Defined
5119 SilcList API over the library because I didn't like the API very
5120 much. See lib/trq/silclist.h for the API and examples of how to
5121 use the API. Fixed various places in the code to use the new
5122 SilcList API. The SilcList is meant for lists that has a structure
5123 already defined as a list. It is not suitable to add just some
5124 context to the list (in TRQ, the context is the list actually).
5126 So, I defined SilcDList that can be used for the purpose where
5127 predefined list structure does not exit. This can be used as
5128 such list. Now some context just can be added to the SilcDList.
5129 Currently this list is not used in the SILC just yet, though there
5130 are a lot places where this can replace dynamically allocated
5131 tables and I will fix these places, later, to use SilcDList.
5132 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5133 and use TRQ internally).
5135 Also fixed some annoying warning messages that the original TRQ
5136 code generated. Also minor changes to TRQ's Makefile.in.
5138 * Added support for querying by Client ID to both WHOIS and
5139 IDENTIFY commands into server, as required by the protocol.
5141 * Removed method function pointers from SilcBuffer structure. They
5142 weren't used to anything and just increased the context size for
5143 no good reason. This change also made silc_buffer_alloc and
5144 silc_buffer_free functions inline functions.
5146 * Disabled command flooding detection support until it's fixed so
5147 that it accepts commands in but does not execute them more than once
5150 * Added silc_net_localhost(), to return local hostname, into
5151 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5152 that must be initialized before calling silc_client_init.
5154 * Added new function: silc_server_send_notify_on_channels to send
5155 notify messages to all channels client has joined. It is assured
5156 that the message is sent only once per client.
5158 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5159 lib/silcutil/silcutil.[ch] as silc_format function. The new
5160 function is generic and is used by server as well, not only by
5161 the logging routines.
5163 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5164 the provided version string was not acceptable. Added new function:
5165 silc_ske_check_version into lib/silcske/silcske.h. The function
5166 must be implemented by the application (client or server) and it
5167 does not reside in the SKE library. The function checks the version
5168 string remote end sent.
5170 * Added back pointers (to opaque context and to SilcSocketConnection)
5171 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5173 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5174 duplicate packet context structure.
5176 * Changed `notify' client operation to send same arguments as client
5177 receives from server except for ID's. ID's are mapped to correct
5178 ID entry and that is returned. Also, if channel entry is not sent
5179 by server but the notify is for channel the channel entry is sent
5180 to application (otherwise application doesn't know that it is for
5181 channel (library gets it from packet's Destination ID)).
5183 * Added silc_client_remove_from_channels into client library to
5184 remove a client from all channels it has joined to. Used when
5185 received SIGNOFF notify from server. Added also new function
5186 silc_client_replace_from_channels to replace old ID entry with
5187 new ID entry on all channels. Used when received NICK_CHANGE
5190 * Fixed ID Cache list handling in silc_idlist_get_client in
5191 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5192 to get (or query) client by ID.
5194 * Updated TODO list.
5196 * Added connection authentication status message defined by the
5197 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5198 support for these into the code in client and server side.
5200 * Added generic function silc_client_send_command to send any command
5201 with variable argument list. Application should use this function
5202 to send commands if the command functions provided by the library
5203 does not suite for the application's user interface needs.
5205 * Added new `failure' client operation. Application is notified about
5206 received failure packet if client is executing a protocol. In this
5207 case the protocol's execution has failed.
5209 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5210 is required by the protocol.
5212 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5213 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5216 * Added status flag to SilcSKE object to indicate realtime status
5217 of the SKE protocol.
5219 * Application receives now exactly same command reply arguments as
5220 the library receives from server. However, if ID is received the
5221 corresponding ID entry is returned to the application (eg. Client
5222 ID is mapped to correct SilcClientEntry entry and that is returned).
5223 Changed command_reply client operation due to this change.
5225 * Changed all ID's in commands and in command replys as ID Payloads.
5226 Change affected both client and server side codes.
5228 All ID's sent in SILC network (with execption of ID's in SILC
5229 Packet header) are sent in ID Payload to support variable length
5232 * Server now notifies nick changes and notifies all clients on
5233 the channels about the new nickname (about the new Client ID,
5236 * Implemented CMODE command to change channel modes. Supports all
5237 channel modes defined by the protocol specs except ban and invite
5238 lists. (Also, private channel key mode is supported but support for
5239 setting private channel key in client is missing, thus, this mode
5240 has no effect on client side (except that server requires that the
5241 client uses private channel key and normal channel traffic does not
5244 Also, invite mode works per se, but INVITE command does not work
5245 yet correctly, so you can set channel as invite only channel but
5246 inviting clients to the channel does not work (it is yet to be
5247 thought what's the best way to do it).
5249 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5250 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5251 Implemented CUMODE command to change user's mode on the channel.
5252 Supports all modes defined by the protocol specs.
5254 * Added NAMES command reply to return users modes on the channel.
5256 * Removed unnecessary and slow ciphers from lib/silccrypt.
5258 * Set SO_KEEPALIVE option to connection sockets by default.
5260 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5262 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5263 redefined the Notify Payload into protocol specs.
5265 * Added silc_id_payload_parse_id to get ID directly from raw
5268 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5271 accept searching by Client ID as well.
5273 * Added support for LEAVE and SIGNOFF notify types in client library.
5275 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5276 to parse ID Payload from raw data.
5278 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added flags parameter into silc_ske_assemble_security_properties
5281 function in lib/silcske/silcske.[ch].
5283 * Changed notify client operation to fit better for notify messages
5284 sent by server. The notify payload received from server is now
5285 passed to the application (after parsing it to SilcNotifyPayload).
5286 It is application's responsibility to retrieve the arguments
5287 from the payload and show the message the way it wants. The message
5288 sent by server is implementation specific.
5290 * Changed public keys to comply with the protocol specification.
5291 Old public keys are not supported anymore and are not compatible.
5293 * Removed nickname from Channel Payload as the latest draft removed
5294 it. The client must resolve the nickname from the NAMES command
5295 reply received when it joined the channel.
5297 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5299 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Fixed some errors in protocol specification drafts.
5303 * Created lib/silccore/silcnotify.c to implement Notify Payload
5304 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5305 generic payloads described by protocol specifications. The file
5306 includes implementations for ID Payload and Argument Payload.
5308 * Changed Command Payload implementation to use the new Argument
5309 Payload. Changed command_xxxx_payload to command_payload_xxxx
5310 to comply with SILC coding conventions.
5312 * Added suppport for Argument Payload handling in Notify Payload
5313 implementation as protocol requires it. Added the new support
5314 into server and client lib as well.
5316 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Added support for multiple nicknames on same channel. [n] is
5319 added locally to the nickname if there are more than one same
5320 nicknames on the channel.
5322 * Server now sends all nicknames that matched WHOIS request.
5323 Client also shows the list received from server.
5325 * Added TOPIC command to client side. User can now set and show
5326 current topic on channel.
5328 * Added MOTD command to client and server. Also, server sends the
5329 motd when client connects to the server.
5331 * Changed version strings to comply ISO 8601.
5333 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Fixed protocol error handling in client library. It should now
5336 cope even if the SKE fails for some reason.
5338 * Made new protocol specification drafts for submitting to IETF.
5340 * Implemented TOPIC command to server in silcd/command.c.
5342 * Added two new notify types into lib/silccore/silcnotify.h:
5343 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5344 notify nickname change and topic setting/change on a channel.
5346 * API change of command_reply operation in client library. The
5347 application gets now the status type received from server as well.
5349 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5353 * Cras fixed and optimized the packet handling even further and
5354 it should work now. Minor change to the prototype of function
5355 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5357 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Added new function into lib/silcutil/silcschedule.[ch]:
5360 silc_schedule_with_fd to select() a specified fd. The function
5361 returns after timeout expires or data arrives or goes. The
5362 function is used by packet routines to wait that all data is
5363 received from network.
5365 * Fixed data reading from network in lib/silccore/silcpacket.c.
5366 The code now assures that all data is read from the fd and then
5367 continues packet processing. This was a bug fix since the code
5368 used to drop some data in some circumstances.
5370 * Added new function into lib/silcclient/client.[ch]:
5371 silc_client_start_key_exchange to start key exchange after
5372 connection has been established to server. The code internally
5373 now uses this funtion but its main purpose was to provide it
5374 for applications that perform their own connecting. After
5375 application has created a connection it merely calls this
5376 function to start the key exchange between client and server.
5377 The library takes care of everything else after that.
5379 Updated also lib/silcclient/README to explain the usage of
5382 * Do not send to application information that connection has
5383 been established. Application gets notified it by connect
5386 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Applied cras's patch to add silc_schedule_one function. The
5389 function runs scheduler once and returns.
5391 * Fixed the scheduler after cras messed it up. The timeout
5392 handling works now as it's supposed to work.
5394 * Added into lib/silccore/ silcnotify.h to include notify
5395 message types support. Changed silc_server_send_notify*
5396 functions, in server.[ch], to support those new notify types.
5397 Added the support for the notify types into client library,
5398 as well. Added new notify client operation into ops.h in
5401 * Changed silc_server_packet_send_to_channel to send normal
5402 packets instead of just channel message packets. The function
5403 is now used to send the notify packets to channels. It is not
5404 used to send channel message packets anymore, as server never
5407 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5408 va_arg()s as it seems to require it nowadays. I guess, if SILC
5409 is compiled with older va_arg() the new code should work anyway.
5411 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Splitted core library. Core library (lib/silccore) includes
5414 now only SILC protocol specific core (and common) components.
5415 Created new utility library (lib/silcutil) that includes more
5416 generic purpose stuff. The stuff for util library was taken
5417 from the old core library. This was minor and easy split.
5419 * Created SILC Client Library (lib/silcclient) that includes
5420 implementation of the SILC client without user interface. This
5421 was major move from silc/ directory. The code has been changed
5422 so that it is transparent towards the user interface. The
5423 silc/ directory includes now the same user interface as before
5424 and it uses the new client library. Read lib/silcclient/README.
5425 Basicly, the client library performs everything else related
5426 to SILC except user interface handling. Also, configuration
5427 files are considered to be part of user interface and library
5428 does not handle them.
5430 This change also changed a lot of structures, function naming etc.
5431 Most important change was that SilcClientWindow object was
5432 renamed to SilcClientConnection in the client library. Created
5433 also new file lib/silcclient/ops.h. Also added new files
5434 silc/local_command.[ch] and silc/client_ops.[ch].
5436 All these changes were made to make it easier for user interface
5437 designers to create what ever user interface for the SILC client
5440 It is also expected that the server will be moved to lib
5441 directory as well and SILC Server Library will be created;
5442 sometimes in the future.
5444 * Removed Local commands from lib/silccore/silccommand.h as
5445 they are application specific and new client library does not
5446 handle any of those anymore.
5448 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5449 old client implementation in silc/.
5451 * Added support for callback functions in SILC_LOG_* macros.
5452 Application can now set its own callbacks that will be called
5453 instead of using the default functions that will always print
5454 the debug messages to stderr (or stdout). Also, debugging can
5455 now be disabled by setting silc_debug to FALSE and re-enabled by
5456 setting it to TRUE. Note, that logging will still work even
5457 if debugging is disabled.
5459 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5460 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5461 silc_log_reset_debug_callbacks.
5463 * To enable debugging in silc client one must give now -d
5464 option on command line.
5466 * Changed silc_schedule_init to automatically allocate task queues
5467 if they are not allocated before calling it.
5469 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Added GMP 3.1 into math library.
5473 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5476 a channel in SILC network. The packet is used by servers and
5477 routers to notify other routers that user has left a channel.
5478 This little feature was missing until now. Added the feature
5479 to protocol specification as well.
5481 Added functions: silc_server_send_remove_channel_user and
5482 silc_server_remove_channel_user into server.[ch].
5484 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5485 lib/silccore/silcpacket.h. However, they are not implemented
5488 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Fixed joining to a channel and sending channel messages
5491 between server and router. The channel message sending should
5492 now work inside a cell.
5494 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Fixed the private message sending between server and router.
5497 The private message sending should now work inside a cell.
5499 * Added silc_server_replace_id into server.[ch] to replace
5500 existing ID in the SILC network.
5502 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5503 and silc_idlist_replace_server_id into idlist.[ch] in server.
5505 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Fixed the server to server connections. Server can again now
5508 connect to router. Router to router connections probably does
5511 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added dynamic protocol registering support. Now protocols can
5514 registered and unregistered on the fly. Patch by cras.
5516 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Added lib/contrib directory to hold routines that some platforms
5519 don't have but are needed by SILC.
5521 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5522 into lin/contrib to provide getopt() and getopt_long() for
5523 those who don't have it.
5525 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added AWAY command to client. When away message is set and
5528 client receives a private message packet the client automatically
5529 replies to the sender with the away message.
5531 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5532 bug seemed to be the cause of recent problems when compiling
5535 * Added version detection support to SKE protocol specification
5536 and added the new changes to the SKE implementation as well.
5537 There were other minor changes in the SKE protocol as well.
5539 Many changes in lib/silcske/silcske.[ch] and in
5540 lib/silcske/payload.[ch].
5542 * Added ^U functionality, clear input line. Patch from cras.
5544 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Mainly small bugfixes on core library. Fixed some debugging
5547 logging and buffer overflow in silclog.c.
5549 * Updated config.sub and config.guess on the distribution tree.
5551 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added command lagging support in server. Client may execute
5554 commands now only once in two seconds.
5556 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Optimized packet reception. MAC computation and checking is now
5559 also more optimized. A lot previously duplicated code is now
5560 used as generic by both client and server.
5562 * Fixed key pair generation in clientutil.c
5564 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added into lib/silccore/silcbufutil.[ch] new function;
5567 silc_buffer_realloc.
5569 * Moved generic packet sending/encryption functions to
5570 lib/silccore/silcpacket.[ch] from client and server. Some
5571 rewriting of the functions.
5573 * Moved all generic packet reception/decryption functions to
5574 lib/silccore/silcpacket.[ch] from client and server. The
5575 packet processing is now much cleaner in both client and server.
5576 These were major changes in both client and server.
5578 * Created many common functions in server to do packet sending.
5579 Previously code were duplicated a lot, this has been removed
5582 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Rewrote major parts of the ID cache system. Don't know
5585 whether it is better now or not but at least the API is more
5588 * Major rewrite on ID cache stuff on client because of the ID
5589 cache API changes. Added idlist.c to client.
5591 * Also major rewrite on ID cache stuff on server as well.
5592 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5593 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5594 in hand, instead they are all put into the ID cache system now.
5595 All server_idlist_* routines uses ID cache now instead of
5596 traversing its own lists (those lists does not exist anymore).
5597 SilcIDList though still exists. Also, SilcXXXEntry's are
5600 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Finally made the SKE implementation compliant to the protocol
5603 specification. All mp integers are now binary encoded as
5604 opposed being HEX encoded.
5606 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5609 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5610 functions: silc_[encode/decode]_pem. Also added function
5611 silc_encode_pem_file to PEM encode with newlines ('\n') for
5614 * SILC public keys are now encoded either PEM or binary. Same
5615 option is for private keys as well. By default private keys
5616 are binary encoded and public keys PEM encoded. Silly HEX
5617 encoding were removed.
5619 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5620 function to create fingerprints.
5622 * Fixed a bug in SHA1; does not change the original data anymore.
5624 * Partly implemented INFO command on client and server side.
5625 Fixed CLEAR command. Changes to SERVER command; show current
5626 server(s) when giving command without arguments. Added
5627 VERSION command to client.
5629 * Added check to server that unregistered connections cannot
5630 execute commands (unless it is specificly allowed).
5632 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Fixed screen refresh.
5636 * Fixed channel joining bug from client. On some circumstances
5637 client tried to join to a channel it had already joined.
5639 * Added public key verification process into client's protocol.c.
5640 The client now verifies the public key from user and saves
5641 it into ~./silc/serverkeys/ directory.
5643 Added into: clientutil.[ch]: silc_client_verify_server_key.
5645 * Changed SKE protocol's silc_ske_initiator_finish function
5646 to accept callback function that verifies the received public
5647 key. Removed old silc_ske_verify_public_key function.
5649 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5652 silc_pkcs_private_key[_data]_set.
5654 * Made the password and public authentication more cleaner in
5655 server's protocol.c.
5657 * Removed historic and obsolete protocol `channel_auth' from
5658 both client and server.
5660 * Removed wrong way of sending command status messages from
5661 server to client in server's command.c. The old way violated
5662 protocol specification.
5664 Changes to silccore/silccommand.[ch]: removed
5665 silc_command_encode_status_payload -> not needed anymore,
5666 changed silc_command_encode_payload_va to accept extra
5667 argument on variable argument list. The argument type must
5668 now be provided to the function. Also, added new function:
5669 silc_command_encode_reply_payload_va which is same as
5670 normal command_encode_payload_va except command status type
5671 is provided as extra argument.
5673 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Added ~./silc directory handling. The directory includes the
5676 public and private keys for the client.
5678 Added silc_client_check_silc_dir, silc_client_create_identifier
5679 and silc_client_load_keys.
5681 * Implemented SILC protocol compliant public key. Added public
5682 and private key saving to and loading from files.
5684 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5685 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5686 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5687 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5688 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5690 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5691 silc_pkcs_load_[public/private]_key.
5693 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Added silc_server_get_route (route.[ch]) to get connection
5696 data for the fastest route for given ID.
5698 * Implemented INVITE command on client and server. The command
5699 were re-defined in the SILC Protocol Specification and the
5700 implementation now complies with the specification.
5702 * Implemented PING command on client and server.
5704 * Implemented NAMES command on client and server. The server side
5705 supports currently only normal server not router server yet.
5706 Some changes to NAMES definition in SILC protocol specification.
5708 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Implemented LEAVE command on client and server.
5712 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5713 again. This change was made to the protocol as well. Server
5714 should not violate the protocol specification anymore.
5716 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5719 was tested. SOCKS4 was not but should work anyway.
