9 * Check that newsize in silc_buffer_realloc is larger than
10 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
12 * Added better monitor of file transfers. It now monitors
13 key agreement protocol during the file transfer too. Added
14 error reporting too. Affected files

37 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Assure that silc_client_notify_by_server_resolve does not
40 resolve the client information multiple times. If it cannot
41 be found by the first it cannot be found at all. Affected
42 file lib/silcclient/client_notify.c.
44 * Fixed WHOWAS command reply calling. Affected file
45 lib/silcclient/command_reply.c.
47 * Removed all references to silc_idlist_get_client from the
48 Irssi SILC client since that call is internal call used by
49 the library. The Irssi SILC client will use now client
50 retrieval functions found in silcapi.h.
52 * Fixed a bug in resolving nickname info before sending
53 private message. It used freed memory. Affected file
54 irssi/src/silc/core/silc-servers.c.

76 Affected file lib/silcutil/silcnet.[ch].
78 * If key exchange or rekey protocol is active for a connection
79 parse all packets syncronously since there might be packets
80 in packet queue that we are not able to process without first
81 processing packets before them. Affected file silcd/server,
82 lib/silcclient/client.c.
84 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
85 whether library should continue processing the packet.

121 * Resolve the client info when received private message or
122 channel message for a client which nickname we don't know.
123 Affected files lib/silcclient/client_prvmsg.c and
124 lib/silcclient/client_channel.c.
126 * Do not crash in /KEY if client is not connected. Affected
127 file irssi/src/silc/core/silc-channels.c.
129 * Added SilcClientStatus field to the SilcClientEntry in the
130 lib/silcclient/idlist.h.
132 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
133 is incomplete and is being resolved, it won't be resolved
136 Make sure also that USERS command reply does not resolve
137 twice information. Affected file is
138 lib/silcclient/command_reply.c.
140 Make sure that silc_client_get_clients_by_list does not
141 resolve twice same information.
143 * Check for valid client->id in the silc_server_free_client_data.
144 Affected file silcd/server.c.

159 * Call the silc_server_udpate_servers_by_server in the
160 primary router that comes back online in the backup resuming
161 protocol. Otherwise it routes packets wrong. Affected file
162 silcd/server_util.[ch], silcd/server_backup.c.
164 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
166 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
167 lib/silcutil/silcbuffmt.[ch].
169 * Redefined the SILC packet header to include the padding
170 length. Affected file lib/silccore/silcpacket.[ch].
172 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
173 length for maximum padding up to 128 bytes). Affected
174 file lib/silccore/silcpacket.h.
176 * Removed all backwards support for old 0.5.x MAC thingies.
177 The SILC packet header change makes it impossible to be
178 backwards compatible.
180 * Send the ENDING packet with timeout in the backup resuming
181 protocol. This is to assure that all routers has connected
182 to the primary router. Affected file silcd/server_backup.c.
184 * Changed the RNG to take the first IV from random data. It
185 used to take it from zero actually. Changed the RNG also
186 to use /dev/urandom during session. /dev/random is used
187 in initialization. Affected file lib/silccrypt/silcrng.[ch].
189 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
191 * Changed the SILC packet header to have the first two bytes
192 (the packet length) encrypted. Affected files aroung the
193 code tree, lib/silccore/silcpacket.[ch]. Removed the
194 SilcPacketCheckDecrypt callback. It is not needed anymore
195 since the silc_packet_receive_process will determine now
196 whether the packet is normal or special.
198 * Implemented the unidirectional MAC keys. Affected files
199 lib/silcske/silcske.c, silcd/protocol.c and
200 lib/silcclient/protocol.c.
202 * Implemented the packet sequence number to the MAC computation.
203 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
204 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
205 lib/silcclient/protocol.c.
207 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
209 * Allow backup router to announce servers. All servers
210 announced by backup router are added to the global list
211 automatically. Update hte server's socket to our primary
212 router also when backup router announces a server.
213 Affected file silcd/packet_receive.c.
215 * Do not update the client->router in the function
216 silc_server_udpate_clients_by_server if the client is on
217 global list. We might fail to find any specific server
218 for locally connected clients and local cell clients. They
219 should still use the `from' and not `to' as client->router.
220 This fixes backup router resuming protocol. Affected file
223 * Decrease channel statistics count only if the channel
224 deletion worked. Affected files are silcd/server.c and
227 * Added silc_server_update_servers_by_server to update origin
228 of all server entries. Used during backup router protocol.
229 Affected files silcd/server_util.[ch], silcd/server.c. and
230 silcd/backup_router.c.
232 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
233 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
234 silc_hmac_get_hash and silc_hmac_get_name. Affected file
235 lib/silccrypt/silchmac.c.
237 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
239 * Assure that router cannot reroute the same channel message
240 to the sender. Affected file silcd/packet_receive.c.
242 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
244 * Made better checks that the channel message is not sent
245 to the router it came from. Affected file is
246 silcd/packet_send.c. Fixed memory leak too.
248 * Announce informations for incoming router connection, but
249 only after checking if it is replaced by backup router.
250 Affected file silcd/packet_receive.c.
252 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Fixed the backup resuming protocol to work in multiple
255 router environment. Affected file silcd/server_backup.c.
257 * Route packet only to one router in the function
258 silc_server_packet_send_to_channel. Affected file is
261 * Fixed silc_server_send_notify_dest to set the broadcast
262 flag. Fixed the silc_server_send_notify_topic to actually
263 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
264 Affected file silcd/packet_send.c.
266 * Changed the SFTP Filesystem interface. Changed the
267 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
268 the filesystem operation function. The SilcSFTPFilesystem
269 is now a context that is allocated by all filesystem allocation
270 functions and it already includes the operations structure
271 and filesystem specific context. It is given as argument
272 now to the silc_sftp_server_start. This made the interface
273 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
274 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
276 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
278 * Changed the backup router adding and getting interfaces
279 in the server. The router that will be replaced by the
280 specified backup router is now sent as argument. Affected
281 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
284 * Added silc_net_addr2bin_ne to return the binary form of
285 the IP address in network byte order. Affected files
286 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
288 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

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

447 entry always, not just when the command is coming from client.
448 Affected file silcd/command.c.
450 * Added new function silc_server_packet_queue_purge to purge the
451 outgoing data queue to the network. After the function returns
452 it is guaranteed that the outgoing packet queue is empty.
453 Affected file silcd/packet_send.[ch].
455 * Purge the outgoing packet queue in the rekey protocol's final
456 callback to assure that all rekey packets go to the network
457 before quitting the protocol. Affected file silcd/server.c.
459 * Added silc_client_packet_queue_parse as similar function as
460 in server to the client library. The affected file is
461 lib/silcclient/client.c.
463 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Splitted silcd/server.c and created silcd/server_util.[ch]
466 for utility functions.
468 * Added new socket flag SILC_SF_DISABLED to indicate that the
469 connection is open but nothing can be sent to or received from
470 the connection. Affected file lib/silcutil/silsockconn.[ch].
471 The checking for disabled socket is checked in the low level
472 silc_socket_write and silc_socket_read functions.
474 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Allow only nicknames and channel names that fits into the
477 7-bit unsigned char ASCII set. Affected file silcd/command.c.
479 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
481 * When processing JOIN command reply in server check that if
482 the channel exists in our global list we'll move it the local
483 list. Affected file silcd/command_reply.c.
485 * Fixed the check whether client is joined on the channel already
486 in JOIN command. Affected file lib/silcclient/command.c.
488 * Fixed the JOIN command reply to check whether the channel
489 already exists. Affected file lib/silcclient/command_reply.c.
491 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Added silc_ske_status_string to map the SKE error numbers
494 to readable strings. The affected files are
495 lib/silcske/silcske[_status].[ch].
497 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Do not show the private channels on the WHOIS channel list
500 as it is not allowed by the protocol. The affected file is
503 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Assure that the packet length digged from the actual packet
506 is something sensible in the silc_packet_decrypt_rest_special
507 in lib/silccrypt/silcpacket.c.
509 * Free and NULL the allocated pointer in silc_hmac_alloc if
510 the HMAC allocation fails. The affected file is
511 lib/silccrypt/silchmac.c.
513 * Print the selected security properties to the log files in
514 the server. Affected file silcd/protocol.c.
516 * Add SKE's reference counter even if calling the completion
517 callback manually. Otherwise it goes negative, although it
518 does not cause any problems. The affected file is
519 lib/silcske/silcske.c.
521 * Remove the client entry with short timeout after giving the
522 KILL command. Affected file lib/silcclient/command.c.
524 * Fixed to send error reply in WHOIS and IDENTIFY commands in
525 case all found clients are already disconnected (WHOWAS would
526 found them) in the server. Affected file silcd/command.c.
528 * Update the last_receive (time of last data received) to be
529 updated only when received private or channel message so that
530 the idle time showed in WHOIS makes more sense.
532 * Added boolean field `valid' in to the SilcClientEntry in the
533 client library to indicate whether the entry is valid or not.
534 This fixes the nickname change bug on channel when changing
535 the nickname to be same than the old (like nick to Nick) the
536 nickname formatter doesn't set the new nick anymore to Nick@host.
537 Affected file lib/silcclient/idlist.[ch].
539 * Now actually fixed the nickname changing on disconnection.
540 Added new function silc_change_nick to the Irssi SILC Client.
541 Affected file irssi/src/silc/core/client_ops.c,
542 irssi/src/silc/core/silc-nicklist.[ch].
544 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

547 trying to encode it. Affected file silcd/command.c.
549 * Print some notifications on received public keys with GETKEY
550 command in the Irssi SILC Client. Affected files are
551 irssi/src/fe-common/silc/module-formats.[ch],
552 irssi/src/silc/core/client_ops.c.
554 * Use IDENTIFY command to resolve the server information in the
555 GETKEY command instead of INFO command. Affected file
556 lib/silcclient/command.c.
558 * All command reply functions in the client library now calls
559 the pending command reply callbacks even if an error has
560 occurred. The server has done this a long time and now it was
561 time to move the client library to this as well. Now all
562 errors can be delivered back to the pending command reply
563 callbacks if necessary. Affected files are
564 lib/silcclient/command[_reply].[ch].
566 * Change the nickname on disconnection back to the username
567 because in reconnect the server will enforce it to it anyway.
568 Affected file irssi/src/silc/core/silc-servers.c.
570 * Fixed a config file parsing bug in the Irssi SILC client.
571 Affected file irssi/src/silc/core/clientconfig.c.
573 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
575 * When printing the channel mode on JOIN, verify that the
576 channel key and channel's HMAC are valid. Affected file
577 irssi/src/silc/core/client_ops.c.
579 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
582 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
583 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
585 * Removed channel key rekey task deleting from the function
586 silc_server_save_channel_key. Affected file silcd/server.c.
587 Added explicit timeout task context instead that is used to
588 delete the task if we are registering a new task before the
589 new task has elapsed.
591 * When channel key rekey occurs the client library now saves
592 the old channel key for a short period of time (10 seconds) and
593 is able to use it in case some is still sending channel
594 messages encrypted with the old key after the rekey. Affected
595 file lib/silcclient/[idlist.h|client_channel.c].
597 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
599 * Added check to the silc_server_new_id_real to not accept
600 new ID if it is the sender's own ID. Affected file is
601 silcd/packet_receive.c.
603 * Assure that we do not announce ourself or the one we've
604 sending our announcements when we're router and are announcing
605 servers to our primary router. Affected file silcd/server.c.
607 * Fixed silc_server_command_identify_check_client to assemble
608 correct WHOIS packet. It send corrupted WHOIS packet and
609 caused problem with router to router connections. Affected
610 file silcd/command.c.
612 Fixed also silc_server_command_whois_check the same way
613 as for the IDENTIFY command.
615 * Added new SilcIDListStatus to the server in the SilcIDListData
616 structure. The status now includes the current status of
617 the entry (like registered, resolved etc.). Affected file
618 silcd/idlist.[ch]. Defined a bunch of different status types
619 as well. This replaced the old boolean registered field as well.
621 Added resolve_cmd_ident field to the SilcClientEntry structure
622 too so that if the entry is for example being resolved so
623 another command may attach to the same pending command reply
624 without requiring to resolve the same entry again. This concept
625 should optimize the WHOIS and the IDENTIFY resolving under
626 heavy load by taking away unnecessary resolving for entries
627 that are being resolved already.
629 Added support for adding multiple pending commands for one
630 command idenfier. Affected file silcd/command[_reply].[ch].
632 * Fixed WHOIS and IDENTIFY save to remove the cache entry
633 before deleting the data. Otherwise the hash table will have
634 freed data in comparison functions. Affected file is
635 silcd/command_reply.c.
637 * Fixed silc_idlist_replace_client_id to add the new entry to
638 the cache with NULL nickname. Otherwise there will be invalid
639 memory as the nickname after the nickname is freed. Affected
640 file silcd/packet_receive.c.
642 * Fixed the silc_idlist_get_clients_by_hash. The entries was
643 saved into wrong slots because the previous number of entries
644 was not taken into account. Affected file silcd/idlist.c.
645 Fixed same thing in silc_idlist_get_clients_by_nickname too.
647 * If we are router and we receive JOIN notify to a channel that
648 does not have any users then notified client is marked as the
649 channel founder, as it is it. The affected file is
650 silcd/packet_receive.c
652 * Added to the extended hash table API's table_del_*ext functions
653 the destructor as argument too, so that the caller can decide
654 which destructor to use or whether to use destructor at all.
655 Affected file lib/silcutil/silchashtable.[ch].
657 * Fixed ID Cache purging. It actually deleted the entries from
658 the hash table after the data was freed. The hash table ended
659 up comparing freed memory. The affected file is
660 lib/silccore/silcidcache.c.
662 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
664 * Fixed Irssi SILC client's KILL command's HELP syntax.
666 * The USERS command now resolves the detailed user information
667 if the userinfo field is missing. Affected file is
668 lib/silcclient/command_reply.c.
670 * Do not print error in silc_file_read if the read file does
671 not exist. Just silently return NULL. Affected file is
672 lib/silcutil/silcutil.c.
674 * Fixed the silc_log_output to not wine about NULL filename
675 and to not create some bogus " " filename. Affected file is
676 lib/silcutil/silclog.c.
678 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Fixed various printing bugs on the user interface in the
681 Irssi SILC Client. Minor changes that were forgotten from
684 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Fixed the configure.in.pre and the compilation and distribution
687 environment to support the new autoconf 2.52. That version is
688 now required to compile the CVS trunk.
690 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Renamed function silc_parse_nickname to silc_parse_userfqdn
693 to generally parse user@fqdn format strings. Affected file
694 lib/silcutil/silcutil.c.
696 * Added nickname_format and nickname_force_format fields to the
697 SilcClientParams structure. The first one defines the format
698 for the nicknames that the library will enforce if the receives
699 multiple same nicknames. The second one is boolean value and
700 can be used to force the library to always enforce the format
701 to the nicknames regardles whether there are multiple nicknames
702 or not. This configurable formatting was employed to flexibly
703 support accessing multiple nicknames from the user interface.
704 The userinterface can now set the nicknames to what ever format
705 they prefer. Affected file lib/silcclient/silcapi.h.
707 Added function silc_client_nickname_format to the file
708 lib/silcclient/idlist.c. It performs the nickname formatting.
710 Added new field `hostname´ to the SilcClientEntry context.
711 It holds the hostname of the client. Affected file is
712 lib/silcclient/idlist.h.
714 * Irssi SILC Client sets the nicknames in nick@hostn format.
715 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
716 irssi/src/silc/core/silc-core.c.
718 The WHOIS printing now also shows both the real nickname and
719 the formatted nickname so that user knows how to access the
720 user if there are multiple same nicknames cached. Affected
721 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
722 printing formatting too to take the hostname now as a separate
723 argument. The Affected file is
724 irssi/src/fe-common/silc/modules-formats.[ch].
726 * Changed the silc_client_get_clients_local to accept the formatted
727 nickname as argument. It accepts the real nickname too but the
728 formatted nickname can be used to find the true entry from
729 multiple entries. Affected file lib/silcclient/silcapi.h and
730 lib/silcclient/idlist.c.
732 * Added nickname_format_parse field to the SilcClientParams.
733 It is a callback function provided by the application to parse
734 the nickname out of the formatted nickname string. The library
735 calls it to get the nickname from the formatted string. Since
736 the application generally knows better the format of the nickname
737 string it parses it instead of the library, even though library
738 encodes the formatted string. If the callback function is not
739 provided then the library will use the string as is. The
740 affected file is lib/silcclient/silcapi.h.
742 * All the nickname strings passed to the client library in
743 commands are now expected to be formatted nickname strings.
744 If the command does not support the formatted nickname string
745 it will assume that the sent string is the actual nickname.
746 Affected file lib/silcclient/command.c.
748 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
750 * Added public key authentication support to OPER and SILCOPER
751 commands in the client library. Affected file is
752 lib/silcclient/command.c.
754 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Changed the get_auth_methdod client operation to be asynchronous.
757 It can be async if the application resolves the authentication
758 method from the server during the negotiation. Added new
759 SilcGetAuthMeth completion callback that the application will
760 call after resolving the authentication method.
762 Added function silc_client_request_authentication_method that
763 the application can use to resolve the authentication method
764 from the server. Added also SilcConnectionAuthRequest callback
765 that the library will call after the server has replied. The
766 application can call this function if it does not know the
767 current authentication method.
769 Affected files are lib/silcclient/client.c and
770 lib/silcclient/silcapi.h.
772 * The Irssi SILC client now automatically resolves the authentication
773 method incase any configuration information is not present (and
774 currently there never is). The affected file is
775 irssi/src/silc/core/client_ops.c.
777 * Fixed public key authentication from the client library.
778 Affected file lib/silcclient/protocol.c. Changed also the
779 protocol specification about the public key authentication in
780 the connection authentication protocol. The actual data to be
781 signed is now computed with a hash function before signing.
783 * Fixed the public key authentication from the server as well.
784 Affected file silcd/protocol.c.
786 * Removed the mlock()'s from the memory allocation routines.
787 Affected file lib/silcutil/silcmemory.c. The ./configure does
788 not check anymore for the mlock(). Affected file is
791 * Fixed USERS command in server to allow the execution of the
792 command for private and secret channels if the client sending
793 the command is on the channel. Affected file silcd/command.c.
795 * Fixed silc_client_get_clients_local to return the clients
796 count correctly. It could return wrong value. Affected file
797 lib/silcclient/idlist.c.
799 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
802 types. The assembler optimizations seemed not to like 64-bit
803 data types. The assmebler optimizations thus are now enabled
804 also for BSD systems as opposed to only enable them for Linux.
806 * Do not check for threads at all on BSD systems. Affected
807 file configure.in.pre.
809 * Removed -n and -h options from the Irssi SILC Client since
810 they are not used in silc.
812 * Fixed the prime generation to assure that the first digit
813 of the generated random number is not zero since our conversion
814 routines does not like number strings that starts with zero
815 digit. If zero digit is seen the random number is regenerated.
816 This caused some corrupted RSA keys when the zero first digit
817 was met. Affected file lib/silcmath/silcprimegen.c.
819 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Fixed WIN32 configuration in the ./configure script.
822 Fixed to include xti.h on environments that has it.
823 Patches by Carsten Ilchmann and andrew.
825 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Changed the silc_id_create_client_id to be collision
828 resistant. It is now assured that there cannot be created
829 two same client ID's. I suspect that some weird bugs in
830 the server were actually caused by duplicate Client IDs.
831 Affected file silcd/serverid.[ch]. A router receiving
832 new ID now also assures and informs the sending server
833 if the ID caused collision.
835 * Changed the silc_id_create_channel_id to also assure that
836 there are no collisions.
838 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Statement about ignoring the Mutual Authentication flag when
841 performing rekey with PFS was a bit misleading. It is ignored
842 if it was set in the initial negotiation, it cannot be even
843 set in the rekey. Fixed in the ke-auth draft. Started the
844 new versions of the protocol drafts in the doc/.
846 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Fixed a bug in silc_client_command_identify_save when saving
849 new channel information. The channel name was no duplicated
850 and caused crash on exit. Affected file is
851 lib/silcclient/command_reply.c.
853 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
855 * Fixed the getkey command handling in the server. Send just
856 empty OK reply to the sender if the key could not be fetched
857 (but everything else was ok, like the key just was not available).
858 Changed the public key parameter to optional in the protocol
859 specs so that empty OK reply can be sent. Affected file
862 Added a message to Irssi SILC client to tell to user if the
863 server did not return a public key.
865 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Fixed a channel key regeneration bug. It registered new
868 timeout tasks exponentially until all system resources were
869 used. Affected file silcd/server.c.
871 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Added the SILC Document generator to the scripts/silcdoc.
874 It can be used to generate the Toolkit Reference Manual out
875 of the source tree. Internally it will also use the RoboDoc
876 generator now imported in util/robodoc.
878 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Added couple of return's in rekey protocol if error orccurred
881 during the protocol. The execution must be terminated.
882 Affected file silcd/protocol.c. Also, terminate the protocol
885 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
887 * The client's Client ID was created initally from the wrong
888 nickname (it could have been in format nick@host) in the
889 silc_server_new_client. Affected file silcd/packet_receive.c
891 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Added some SILC_LOG_ERROR's to various error conditions
894 if client could not be added to ID cache. Affected files
895 silcd/packet_receive.c and silcd/server.c.
897 * When client's sock->user_data is freed, NULL also the
898 client->router and client->connection pointers. Added check
899 for these pointers being NULL to various places around the
900 code. Affected file silcd/server.c.
902 * Added client->data.registered == TRUE checks to various
903 places around the code to assure that unregistered client's
904 are not handled when it is not allowed. Affected file
907 * Added `bool registered' fields to all
908 silc_idlist_[server|client]_get_* routines to indicate whether
909 the fetched client needs to be registered or not. Affected
910 file silcd/idlist.[ch].
912 * Add your own entry as registered to the ID cache in the
913 server. Affected file server.c.
915 * Fixed a bug in silc_server_new_server. The SilcServer was
916 set as the new server's context instead of SilcServerEntry.
917 This naturally caused some weird bugs.
919 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Do not delete the channel rekey task when adding it
922 for in silc_server_create_channel_key.
924 * Changed the silc_server_create_channel_key to return
925 TRUE or FALSE to indicate the success of the channel key
928 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed MSVC++ project files and added missing files to
931 Makefiles under win32/.
933 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Do not add TCP_NODELAY flag if the operating system
936 does not have it defined. Affected files are
937 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
939 * Fixed buffer overflow from Irssi SILC Client. Affected
940 file irssi/src/fe-common/core/themes.c.
942 * Fixed double free in client library in the file
943 lib/silcclient/client.c when disconnecting from server.
945 * Applied double free patch from cras to Irssi SILC client.
946 Affected files irssi/src/core/[modules/expandos].c
948 * Fixed the disconnection handling to Irssi SILC Client.
949 The application must call silc_client_close_connection
950 in ops->connect client operation in case of failure of
951 the connection. Affected file is
952 irssi/src/silc/core/client_ops.c.
954 * Do not set sock->protocol to NULL in the function
955 silc_client_close_connection after executing the protocol's
956 final callback since the sock might not be valid anymore.
957 Affected file lib/silcclient/client.c.
959 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Do not enable SILC_THREADS if the linking with libpthread
962 did not happen. Affected file configure.in.pre.
964 * Added notion to protocol specification that server must
965 verify the sent authentication payload with CMODE when
966 setting the channel founder key. Implemented it to the
967 server. Affected file silcd/command.c.
969 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Added _EXTRA_DIST SILC distribution variable to the
972 distributions file. It is used to conditionally add extra
973 files or directories to the specific distribution. Affected
974 files ./prepare, Makefile.am.pre and distributions.
976 Removed the `_' from the start of the distribution names.
979 * Added README.WIN32 for instructions to compile the Toolkit
982 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Fixed a double free in disconnection in the server. Affected
985 file is silcd/server.c.
987 * Fixed the lib/silcske/groups.c to work now also with GMP
988 MP library. The string conversion did not work when using
989 specific base and the base is indicated in the string as well.
991 * Created win32/ directory which now includes MSVC++ specific
992 stuff so that toolkit (DLLs) may be compiled with MSVC++.
993 It will appear only in the toolkit distribution
995 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
997 * Changed the key material distribution function in case when
998 the hash output is too short. The data is now concatenated
999 a bit differently than it used to. Made the change to the
1000 SKE protocol specification.
1002 * Added better GMP detection to configure.in.pre. A patch
1005 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1007 * Fixed a minor bug in SKE that might cause some problem on
1008 some platforms. Affected file lib/silcske/silcske.c.
1010 * Added the cookie checking for initiator in the SKE. It checks
1011 that the responder returns the sent cookie unmodified. The
1012 affected file is lib/silcske/silcske.c. Added new SKE
1013 error type INVALID_COOKIE that can be sent during the
1014 negotiation. Fixed some memory leaks as well.
1016 * Added the "invalid cookie" error message to Irssi SILC client's
1019 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Added `task_max' field to the SilcClientParams to indicate
1022 the maximum tasks the scheduler can handle. If set to zero,
1023 default values are used. Affected file lib/silcclient/silcapi.h.
1025 * Fixed memory leaks in silc_client_close_connection. Affected
1026 file lib/silcclient/client.c.
1028 * Added silc_client_del_client_entry to client library to free
1029 all memory of given client entry. Affected file is
1030 lib/silcclient/idlist.[ch].
1032 * Added new functions silc_client_del_channel and
1033 silc_client_del_server to delete channel and server entries.
1034 Affected file lib/silcclient/[silcapi.h/idlist.c].
1036 * Removed silc_client_del_client_by_id from silcapi.h.
1038 * Fixed the INFO command to return the server's own info
1039 correctly when querying by Server ID. Affected file is
1042 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Removed the non-blocking settings in WIN32 code in the
1045 silc_sock_[read/write] and added SleepEx instead. Affected
1046 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1047 of input data is now checked with FIONREAD and ioctlsocket.
1049 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Call silc_schedule_task_del_by_context in the
1052 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1053 Affected file lib/silccore/silcprotocol.c.
1055 * Call silc_protocol_cancel for active protocols in the
1056 silc_server_close_connection if the funtion
1057 silc_server_free_sock_user_data has not been called.
1058 Affected file silcd/server.c.
1060 * Generic tasks cannot be deleted using the del_by_fd
1061 task deleting function since generic tasks does not match
1062 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1064 * Added a notion to SILCOPER help file that the SILCOPER works
1065 only on router server, not on normal server.
1067 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Added for WIN32 support for the new scheduler as well.
1070 Affected file lib/silcutil/win32/silcwin32schedule.c.
1072 * Fixed the SHA1 implementation to work on various platforms.
1074 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1077 API. It is part of the scheduler now. Everything else is
1078 as previously but some functions has changed their names.
1079 Checkout the lib/silcutil/silcschedule.h for the interface.
1080 Updated all applications to use the new interface. Affected
1081 files are lib/silcutil/silcschedule.[ch].
1083 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Found a bug in the SKE implementation. The HASH value,
1086 specified by the protocol, was not computed correctly. The
1087 public key of the responder was not added to the computation
1088 even though it is mandatory. Affected file lib/silcske/silcske.c.
1089 This unfortunately causes incompatibilities with older
1090 clients and servers.
1092 * Added WIN32 specific network init and uninit functions:
1093 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1094 the Winsock2. Affected file lib/silcutil/silcnet.h and
1095 lib/silcutil/win32/silcwin32net.c.
1097 * Set the socket always to nonblocking mode on WIN32 after
1098 reading data or writing data. Affected file is
1099 lib/silcutil/win32/silcwin32sockconn.c.
1101 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Fixed various compilation problems under WIN32. Affected
1104 files lib/silcutil/win32/silcwin32thread.c and
1105 lib/silcutil/win32/silcwin32schedule.c.
1107 * Removed all _internal.h #includes from public header
1108 files. Internal headers must never be included from
1111 Removed also the lib/silcske/payload_internal.h file.
1113 * All include files that may be needed (public and some others
1114 included by the public headers) by application developers are
1115 now copied to the ./includes directory. It does not copy any
1116 internal headers. Affected file Makefile.defines.pre and all
1117 Makefile.am's under lib/ and subdirs.
1119 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1121 * Do not change the ~/.silc directory's permissions automatically.
1122 Affected file irssi/src/silc/core/clientutil.c.
1124 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1126 * Do not cancel the protocol in silc_server_close_connection
1127 it might cause recursion. Now cancelled in the function
1128 silc_server_free_sock_user_data. Affected file silcd/server.c.
1130 * Fixed the silc_server_remove_clients_by_server to regenerate
1131 the channel keys correctly finally. Added also new function
1132 silc_server_remove_clients_channels to actually do it.
1133 Affected file silcd/server.c.
1135 * Fixed the silc_server_new_channel to not crash by giving
1136 wrong router to the new channel. Affected file is
1137 silcd/packet_receive.c.
1139 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1142 which is given as argument to the silc_client_alloc now.
1143 It can be used to configure the client and set various parameters
1144 that affect the function of the client.
1146 * The USERS command in server did not check whether the channel
1147 is private or secret. Affected file silcd/command.c.
1149 * Added new argument to the USERS command in protocol specification.
1150 The USERS command now can take the channel name as argument
1151 as well. Added support for this in client and server and
1152 updated the protocol specs.
1154 * Completed the GETKEY command in client. It can be now used
1155 to fetch also servers public key not only some clients.
1156 Affected files lib/silcclient/command[_reply].c.
1158 * Added silc_client_get_server to return server entry by the
1159 server name. Affected files lib/silcclient/silcapi.h and
1162 * Redefined the IDENTIFY command in protocol specification to be
1163 more generic. It now can be used to query information about
1164 any entity in the SILC Network, including clients, servers and
1165 channels. The query may be based either the entity's name
1166 or the ID. Added support for this in both client and server.
1168 Affected files silcd/command.c and lib/silcclient/command.c
1169 and command_reply.c.
1171 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1172 the _from_client and _from_server functions. Affected file
1175 * Added silc_client_get_channel_by_id_resolve to the file
1176 lib/silcclient/silcapi.h to resolve channel information by
1177 its ID. Added also silc_client_get_channel_by_id that
1178 does not resolve it from the server.
1180 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * Added SilcServerEntry context into the client library
1183 to represent one server. The INFO command now allocates
1184 these to save the resolved server info. For now on the
1185 client library will also keep information about servers,
1186 connected and resolved with INFO.
1188 The INFO command now allocates the SilcServerEntry context
1189 and saves the server info there. The COMMAND_REPLY in
1190 the INFO now returns the parameters to application in
1191 same order as defined in the protocol specification.
1193 The entries are cached in the client->server_cache.
1195 * The INFO command is now issued after received the Client ID
1196 from the server. Affected file lib/silcclient/client.c.
1198 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1199 to the application as the mode changer might be server.
1200 It is guaranteed that NULL is not returned anymore to the
1201 application. Affected file lib/silcclient/client_notify.c.
1203 The ID Type is now also passed to the application so that
1204 it can check whether the returned entry is SilcClientEntry
1207 Added new function silc_client_get_server_by_id to return
1208 the server entry by ID. Affected files are the
1209 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1211 * Do not create the channel in the Irssi SILC Client when issuing
1212 the JOIN command but when received the sucessful JOIN command
1213 reply. Otherwise the channel might get created even though we
1214 could not join it. The Affected file is
1215 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1217 * Fixed a channel joining bug in router. The router must also
1218 check the channel modes, invite and ban lists etc. when serving
1219 the JOIN command sent by normal server. Affected file is
1220 silcd/command.c. The router now resolves the client's
1221 information from the server who sent the JOIN command if it
1222 does not know it, and processes the JOIN command only after
1225 * Changed the SilcCommandCb to take new argument; void *context2.
1226 Affected file lib/silccore/silccommand.h
1228 The second argument in the command callbacks in the server now
1229 includes the SilcServerCommandReplyContext if the command was
1230 called as pending command callback from the command reply.
1231 Otherwise it is NULL. When called as pending the status of the
1232 command reply will be checked and if it was erronous the
1233 error will be sent to the original sender of the command.
1234 This way the client always receives the error messages even
1235 though the server was actually the one who received the error
1236 when it resent the command to router, for example. Affected
1237 files silcd/command[_reply].[ch].
1239 * Fixed sending WHOWAS command's error message to client if
1240 the requested client could not be found. It was missing.
1243 * Changed the CMODE and CUMODE commands reply arguments in the
1244 protocol specification. The Channel ID is now sent in both
1245 of the commands to identify the channel. Implemented this
1246 new feature to the client and server. Affected files
1247 lib/silcclient/command_reply.c and silcd/command.c.
1249 * Made better checks for invite and ban lists in the JOIN
1250 command in server. Affected file silcd/command.c.
1252 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1254 * The server now performs the incoming host IP/DNS lookup
1255 using the silc_socket_host_lookup and thus does not block
1256 the server anymore. Affected file silcd/server.c.
1258 * Completed the multi-thread support for SILC Scheduler in
1259 the lib/silcutil/silcschedule.c.
1261 * Fixed the configure.in.pre to detect the pthread correctly
1264 * Fixed a deadlock in silc_task_queue_wakeup in the file
1265 lib/silcutil/silctask.c.
1267 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Added new function silc_schedule_wakeup that is used in
1270 multi-threaded environment to wakeup the main thread's
1271 schduler. It needs to be used when a thread adds a new task
1272 or removes a task from task queues. After waking up, the
1273 scheduler will detect the task queue changes. If threads
1274 support is not compiled in this function has no effect.
1275 Implemented the wakeup mechanism to both Unix and WIN32
1276 systems. Affected files are lib/silcutil/silcschedule.[ch],
1277 lib/silcutil/unix/silcunixschedule.c and the
1278 lib/silcutil/win32/silcwin32schedule.c.
1280 * Added new function silc_task_queue_wakeup to wakeup the
1281 scheduler by the specified task queue. Affected file
1282 lib/silcutil/silctask.[ch].
1284 * The silc_socket_host_lookup_start now wakes up the scheduler
1285 after adding the timeout task. Affected file is
1286 lib/silcutil/silcsockconn.c.
1288 * The silc_socket_host_lookup is synchronous now if the threads
1289 support is not compiled in. However, the callback is still
1290 called asyncronously through the scheduler, anyway. Affected
1291 file lib/silcutil/silcsockconn.c.
1293 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Added new function silc_socket_host_lookup to perform
1296 asynchronous IP and FQDN lookups for the socket connection.
1297 Affected files lib/silcutil/silcsockconn.[ch].
1299 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1302 that may or may not compile the mutex support in.
1304 Changed the silc_mutex_alloc interface. It allocates the
1305 mutex now to the sent pointer and returns TRUE or FALSE.
1307 Affected file lib/silcutil/silcmutex.h.
1309 * Wrote the SILC Task Queue interface to support multi-threads.
1310 Affected file lib/silcutil/silctask.[ch].
1312 * Wrote the SILC Scheduler to support multi-threads. Affected
1313 file lib/silcutil/silcschedule.c.
1315 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1318 in lib/silcutil/win32/.
1320 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Defined SILC Mutex API and SILC Thread API and implemented
1323 them for Unix. Affected files are
1324 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1325 lib/silcutil/unix/silcunixmutex.c and
1326 lib/silcutil/unix/silcunixthread.c.
1328 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * Fixed the silc_server_remove_clients_by_server's channel
1331 key re-generation. The hash table handling was incorrect
1332 and would not work with many channels. Affected file is
1335 * Fixed some memory leaks around the server code.
1337 * Rewrote the silc_server_get_users_on_channel to support IPv6
1338 based Client ID's. Affected file silcd/server.c.
1340 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1341 specification. However, a separate document must be written
1342 to define the detailed signing procedure and the payload
1343 associated with the flag. Defined the flag to the
1344 lib/silccore/silcchannel.h as well.
1346 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Changed the dynamic tables to static size tables in the
1349 lib/silccrypt/silchmac.c.
1351 * Removed GCC dependencies from the code. A patch by cras.
1353 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1355 * Do not show the error "Error receiving packet bla bla"
1356 in server if it really was not an error (-2 means that reading
1357 is pending). Affected file silcd/server.c.
1359 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Fixed a possible crash in silc_server_remove_clients_by_server
1362 in silcd/server.c. Fixed there also some memory leaks.
1364 * Fixed the silc_idlist_replace_client_id. It could replace
1365 wrong key in the hash table. Affected file silcd/idlist.c.
1367 * Do not check whether there are global users on the channel
1368 if the channel->global_users is FALSE. Affected functions
1369 silc_server_remove_from_one_channel and
1370 silc_server_remove_from_channels in silcd/server.c. Also,
1371 do not check if the removed client is local as we can be
1372 sure that global client was not removed from the channel
1373 and checking for global users is not needed.
1375 * The silc_server_remove_clients_by_server now re-generates
1376 the channel keys correctly for those channels that had
1377 clients removed from them. Affected file silcd/server.c.
1379 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Found the reason of random crashes in the server. We weren't
1382 ignoring the SIGPIPE signal (which can be sent in write())
1383 and it crashed the server. Affected file silcd/silcd.c.
1385 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Assure that sock->user_data is not NULL in the function
1388 silc_server_packet_send in silcd/packet_send.c.
1390 * Disconnect the remote connection if it could not be added
1391 to any ID lists in the server. The affected file is
1394 * Check in silc_server_packet_send[_real/dest] that the
1395 socket is not disconnecting and ignore the data if it is.
1396 Affected file silcd/packet_send.c.
1398 * Define inline to __inline on native WIN32 compilation.
1399 Affected file includes/silcwin32.h.
1401 * Added some explicit type casts for inline code since MSVC
1402 require them. Affected files lib/silcutil/silcbuffer.h,
1403 lib/trq/silcdlist.h and lib/trq/silclist.h.
1405 * Print warning in log files from now on if the packet
1406 decryption fails. Affected file silcd/server.c.
1408 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Changed the `say' client operation's interface to accept
1411 new `type' argument to indicate the type of the message sent
1412 by the library. The application may filter the library's
1413 messages according the type. The affected file is the
1414 lib/silcclient/silcapi.h.
1416 * Added two new functions to lib/silcclient/silcapi.h:
1417 silc_client_del_client and silc_client_del_client_by_id.
1418 Affected file lib/silcclient/idlist.c.
1420 * Moved the clientincludes.h from includes/ to silc/ and
1421 serverincludes.h from includes/ to silcd/.
1423 * The modes for the CMODE and CUMODE are now passed as
1424 uint32 for application with COMMAND_REPLY. The affected
1425 file is lib/silcclient/command_reply.c.
1427 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * /WHOIS without arguments shows client's own information.
1430 Affected file lib/silcclient/command.c.
1432 * Changed PING to not accept any arguments. The specs
1433 says that client can ping only the connected server so
1434 requiring an argument is not needed. Affected file is
1435 lib/silcclient/command.c.
1437 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Fixed a fatal bug in private message sending and reception
1440 encryption and decryption when using private message keys.
1441 The implementation was incorrect and did not follow the
1442 specification. It causd that some of the message were
1443 lost since it did not use the sending and receiving keys
1444 as the protocol suggests. This has been fixed and will cause
1445 incompatibilities with older clients when sending private
1446 message encrypted with private message keys. Affected files
1447 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1448 and various other in Irssi SILC Client.
1450 Added `responder' boolean argument to the functions
1451 silc_client_add_private_message_key[_ske] to indicate when
1452 the key is added as responder or initiator of the key
1455 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Removed the silc_ske_check_version function and created
1458 a SilcSKECheckVersion callback. Added also a function
1459 silc_ske_set_callbacks that is now used to set all SKE
1460 callbacks. The callback functions are not given to
1461 the SKE functions anymore, but this function is used to
1464 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1466 * Added `silc_version' argument to the silc_client_alloc
1467 to define the version of the application for the library.
1468 The library will use the version string to compare it
1469 against the remote host's (usually a server) version
1470 string. Affected file lib/silcclient/silcapi.h
1472 * Added the KE protocol context to Key Agreement context
1473 in client library so that we can abort the SKE if it
1474 is in process when we get timeout. Affected file is
1475 lib/silcclient/client_keyagr.c.
1477 * Do not resolve the client ID forever if it returns in the
1478 first time that such client does not exist. This was done
1479 for example with private message. Affected file is
1480 lib/silcclient/client_prvmsg.c.
1482 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Do not add regex.h for WIN32. The affected file
1485 includes/silcincludes.h.
1487 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1488 not work yet 100%. It generates the DLL's automatically
1489 when compiling with --with-win32 under cygwin.
1491 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * lib/contrib/regex.c is not compiled on WIN32.
1495 * Added silc_net_get_socket_opt function to the
1496 lib/silcutil/silcnet.h.
1498 * Added includes/silcwin32.h for WIN32 specific includes
1501 * Do not use ptime structure or any of the posix process
1502 functions on WIN32 in lib/silccrypt/silrng.c.
1504 * Added silc_gettimeofday to provide generic function
1505 for struct timeval on all platforms. Added the function
1506 to lib/silcutil/silcutil.h.
1508 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1511 library as they clearly belong there. As a plus side we
1512 can make the actual socket connection routines platform
1515 Added also new generic function silc_socket_read and
1516 silc_socket_write (that used to be silc_packet_[read/write].
1517 The implementation of these are platform specific.
1519 * Added WIN32 specific routines of silc_socket_[read/write]
1520 to lib/silcutil/win32/silcwin32sockconn.c.
1522 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Added preliminary support for native WIN32 compilation under
1525 cygwin (using the -mno-cygwin option for GCC) to the
1526 ./configure.in.pre. The --with-win32 now prepares the
1527 compilation for native WIN32.
1529 * Rewrote the SILC Scheduler interface in the file
1530 lib/silcutil/silcschedule.h. The scheduler is now context
1531 based and does not have anymore any global static scheduler.
1532 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1533 and created lib/silcutil/win32 directory for WIN32 based
1536 * Added Unix specific network routines to the
1537 lib/silcutil/unix/silcunixnet.c and the old
1538 lib/silcutil/silcnet.c includes now only generic routines.
1540 Added WIN32 specific network routines to the
1541 lib/silcutil/win32/silcwin32net.c.
1543 * Added Unix specific utility functions from the
1544 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1546 * Added WIN32 SILC Scheduler to the file
1547 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1550 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Do not handle JOIN notify in the server if the target client
1553 is not registered (idata->registered == FALSE). The affected
1554 file is silcd/packet_receive.c.
1556 * Update the nickrec->founder in event_cumode in the Irssi SILC
1557 client. Affected file irssi/src/silc/core/silc-channels.c.
1559 * Fixed the CUMODE_CHANGE notify handling in the server when
1560 server and router are announcing their clients on channels.
1561 Now the mode changes are saved and notified correctly. The
1562 affected file is /silcd/packet_receive.c.
1564 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1565 They really did not replace the cache entry in the ID Cache.
1566 Now they do that. Affected file silcd/idlist.c.
1568 * Fixed the KICK notify handling in the Irssi SILC client to
1569 update the channel records so that the kicked client does not
1570 appear to be on the channel. The affected file is
1571 irssi/src/silc/core/silc-channels.c.
1573 * Always update the conn->current_channel when executing command
1574 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1576 * Fixed the KILL notify handling in Irssi SILC client to remove
1577 the killed client on all channels.
1579 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Fixed the silc_parse_command_line to remove extra spaces
1582 from the start and end of the arguments. Affected file is
1583 lib/silcutil/silcutil.c.
1585 * Cancel and free any active protocol in the function
1586 silc_server_close_connection. Affected file silcd/server.c.
1588 * Cancel and free any active protocol in the function
1589 silc_client_close_connction. Affected file is
1590 lib/silcclient/client.c.
1592 * Do not execute the KILL command for clients that are in
1593 history (ie. they are not in the network). Affected file is
1596 * Fixed KILL notify handling, client does not crash anymore.
1597 Affected file irssi/src/silc/core/silc-channels.c.
1599 * Reduced the default packet buffer size from 2048 to 1024 in
1600 lib/silccore/silcpacket.c.
1602 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1603 counter to the SKE context that is incresed when the SKE library
1604 performs async operation outside the library. If the outside
1605 process frees the SKE context and FREED status will be set
1606 and the library will detect after the sync operation that the
1607 libary is freed. The affected files are
1608 lib/silcske/silcske[_status].[ch].
1610 * Resolve the client entry information in the function
1611 silc_client_channel_message to assure that NULL pointer is not
1612 passed as client entry to the application. */
1614 * Fixed the task timeout calculation to assure that there is
1615 never negative timeouts. The affected file is
1616 lib/silcutil/silcschedule.c.
1618 * Fixed the channel user mode notification sending in server.
1619 It was sent point-to-point to the router (or to server by router)
1620 but it needs to be destined to a channel. The routines now
1621 supports sending the channel user mode notifys to the channels
1622 when announcing clients and channels. Affected files are
1623 silcd/server.c and silcd/packet_receive.c.
1625 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1626 It did not actually replace the old channel entry in the cache.
1627 Affected file lib/silcclient/client_notify.c.
1629 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1631 * Fixed a possible crash in silc_packet_send_prepare. It now
1632 assures always that there is enough space in the buffer and
1633 at the tail area of the buffer (for MAC).
1635 Fixed the inbound buffer reallocation in silc_packet_read.
1636 It was old code and did not handle the reallocation correctly.
1639 The affected file is lib/silccore/silcpacket.c.
1641 * Fixed buffer overflow in silc_parse_nickname in the file
1642 lib/silcutil/silcutil.c.
1644 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * make install generates new server keys only if there is not
1649 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1652 Added check that if the NOREPLY is set then we will not send
1653 the away message. This avoids infinite loop of away messages
1654 if both clients are away. The affected file is
1655 lib/silcclient/client_prvmsg.c.
1657 * Fixed client crash if /NICK was given without arguments.
1658 Affected file lib/silcclient/command.c.
1660 * Server does not send the invite list in INVITE command back
1661 to the client if the list was not altered. Added this notion
1662 to the protocol spec as well. Affected file silcd/command.c.
1664 Fixed possible crash in INVITE command by checking the
1665 value of silc_server_get_client_route command.
1667 * Fixed the INVITE notify type handling. The arguments are now
1668 taken in correct order and client does not crash. The affected
1669 file is irssi/src/silc/core/silc-channels.c.
1671 Removed the "Inviting xxx to channel" message from the
1672 client library away and let the application handle it.
1673 Affected file lib/silcclient/command.c. Added that message
1674 to Irssi SILC client's message formats.
1676 * Fixed CMODE command crash in client. It now checks the
1677 amount of arguments correctly and does not crash. The affected
1678 file is lib/silcclient/command.c.
1680 * Do not create new channel automatically in silc_channels_join
1681 but check whether the channel by that name already exists.
1682 Affected file irssi/silc/core/silc-channels.c.
1684 * Do not send the SERVER_SIGNOFF to router if the disconnected
1685 entity was the router. Affected file silcd/server.c.
1687 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1688 SILC client as it was missing from there.
1690 Added the handling of the KICK notify to the Irssi SILC client
1691 as it was missing. Added "you have been kicked" message to
1692 Irssi SILC client's message modules formats.
1694 Added the handing of the KILL notify to the Irssi SILC client
1695 as it was missing. Added the kill message module formats
1698 The affected file is irssi/src/silc/core/silc-channels.c.
1700 * The router did not save the channel mode the server announced.
1701 Affected file silcd/packet_receive.c.
1703 * Fixed a possible crash in INFO command in server. If the
1704 server did not provide the server info it crashed. Affected
1705 file silcd/command.c.
1707 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * Fixed the GETKEY command in the server to check also the
1710 global list. Otherwise the GETKEY would not work correctly
1711 in normal SILC server. Affected file silcd/command.c.
1713 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Fixed GETKEY crash, it crashed if the command did not succseed.
1717 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1720 is now real and not just an macro interface to GMP.
1722 Removed the entire GMP from the source tree and imported new
1723 NSS MPI library instead. Reason for removing GMP is that it is
1724 extremely large and compiles extremely slow. The NSS MPI
1725 is only a few files and compiles in less than 10 seconds.
1726 The speed is also about the same as GMP. The MPI is imported
1727 to lib/silcmath/mpi.
1729 If the system has GMP installed we will still use the GMP.
1730 If it is not then the NSS MPI will be compiled.
1732 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Merged a long nickname (127 characters long) crash bugfix from
1735 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1737 * Merged a freed memory reference bugfix from Irssi CVS tree.
1738 Affected file irssi/src/core/commands.c.
1740 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added the server's public key sving and verification to the
1743 server when performing the SKE. This was missing and the
1744 remote server's (or router's) public key was accepted without
1745 checking whether we have it previously or trust it at all.
1746 Affected file silcd/protocol.c.
1748 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Check in the silc_server_timeout_remote if protocol is active
1751 and make sure that the protocol's final callback is called so
1752 that all memory if freed. Affected file silcd/server.c.
1754 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1756 * silc_server_whois_send_reply crashed the server if the nickname
1757 was 127 characters long. Affected file silcd/command.c.
1759 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1761 * Added sanity check to the silc_server_new_client. If the hostname
1762 is provided inside username then check that the provided hostname
1763 really is the same as the resolved one. If the hostname was not
1764 resolved then check it from the public key. Affected file is
1765 silcd/packet_receive.c.
1767 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1768 if the server disconnected us and the connection is not valid
1769 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1771 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1772 the library to the lib/silcutil/silcutil.[ch].
1774 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Close log file after open. Affected file
1777 lib/silcutil/silclog.c.
1779 * Check whether sock == NULL in silc_client_send_packet and return
1780 if it is. Affected file lib/silcclient/silcclient.c.
1782 * Check rec->entry == NULL in the Irssi SILC Client before
1783 sending the channel message. Affecte file is
1784 irssi/src/silc/core/silc-servers.c.
1786 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Merged a splitted window bugfix from Irssi CVS tree. The
1789 affected file is irssi/src/fe-text/textbuffer-view.c.
1791 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1792 It did not print nickname.
1794 * Improved the distributions system a bit.
1796 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1799 irssi/src/fe-text/gui-window.c.
1801 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1802 to in-active server. The affected file is
1803 irssi/src/silc/core/client_ops.c.
1805 * Resolve the client in USERS command reply if the entry does
1806 not have username resolved. The affected file is
1807 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1808 command to WHOIS command to really resolve stuff. The USERS
1809 is not used any more in any critical section so WHOIS can
1810 be used even though it might be slower than IDENTIFY.
1812 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1815 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Changed the protocol API a bit more consistent in the
1818 lib/silccore/silcprotocol.[ch].
1820 * Changed the following headers to ROBODoc format:
1822 lib/silccore/silcpayload.h
1823 lib/silccore/silcprotocol.h
1824 lib/silccore/silcsockconn.h
1826 All core library headers are now formatted.
1828 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * Fixed a bug in Irssi SILC client; do not show that you are
1831 server/router operator if you really are not. Affected file is
1832 irssi/src/silc/core/client_ops.c.
1834 * Renamed silc_command_free_payload to silc_command_payload_free.
1835 Affected file lib/silccore/silccommand.h
1837 * Added silcmath.h to include the prototoypes of various routines
1838 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1841 * Changed the following headers to ROBODoc format:
1843 lib/silccore/silcchannel.h
1844 lib/silccore/silccommand.h
1845 lib/silccore/silcid.h
1846 lib/silccore/silcidcache.h
1847 lib/silccore/silcmode.h
1848 lib/silccore/silcnotify.h
1849 lib/silccore/silcpacket.h
1850 lib/silcmath/silcmath.h
1852 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * Added checking to the server code not to start the server if
1855 ciphers and stuff are not configured properly. Affected files
1856 silcd/serverconfig.[h] and silcd/server.c.
1858 * Changed the layout of the header files of the public interfaces
1859 in the SILC libraries. The new layout supports ROBODoc
1860 documentation tool (and some others) so that it is easy to create
1861 a library reference manual. All the other headers and source
1862 code must still follow the CodingStyle document. Also source
1863 code must not include these ROBODoc stuffs, only the headers.
1864 Furthermore, all public interface headers must now be named
1865 by using `silc' prefix, example: silcapi.h, silccipher.h.
1866 Some files were renamed due to this. All the other headers
1867 must not be used as public interfaces. I will update the
1868 CodingStyle document later. Changed following headers, so far:
1870 lib/silcclient/silcapi.h
1871 lib/silccore/silcauth.h
1872 lib/silccore/silcprivate.h
1873 lib/silccrypt/silcdh.h
1875 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Removed silc_client_packet_send_flush from the client library
1880 as it is not needed. Affected file lib/silcclient/client.[ch].
1882 * Added printing of message of unresolved authentication method
1883 to the Irssi SILC client. Added it to the module formats.
1884 Removed the same message from the client library.
1886 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Added new distribution feature, DISTLABEL. Every distribution
1889 can define own preprocessor label that can be used in the
1890 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1891 file distributions, acconfig.h.pre and prepare.
1893 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1895 * Added Makefile.defines_int to include the actual definitions
1896 for Makefile.defines.in. Tested the new distribution system,
1897 created distributions and tested installation.
1899 * Added AWAY message printing to the Irssi SILC client. Added
1900 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1902 * Added SCONNECT command to call the SILC's CONNECT command.
1903 Cannot use CONNECT directly since Irssi uses that internally.
1904 Affected file irssi/src/silc/core/silc-servers.c.
1906 Added ACTION local command. It is same as ME command but takes
1907 the channel as mandatory argument.
1909 Rewrote some of the Irssi's help files to suite for SILC
1912 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Added Makefile.defines[.in] that should for now on be included
1915 in all Makefile.am file in the source tree. That file includes
1916 all common compilation definitions for SILC source tree.
1918 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Minor changes to the ./prepare script to change the package
1921 name according the distribution name to the configure.in.
1923 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Created new distribution system. Added file `distributions'
1926 that defines all the distributions that can be created out of
1927 the SILC source tree. The ./prepare script now reads that
1928 file to determine how to prepare the distributions. The
1929 first argument to the ./prepare is the name of the distribution
1930 and second is the version of the distribution. If given
1931 without arguments it creates the default (toolkit) distribution
1932 with the default version (defined in ./prepare).
1934 All Makefile.am files that are subject to the distributions
1935 are now named as Makefile.am.pre. These are ./Makefile.am
1936 and lib/Makefile.am. Others may be changed later.
1938 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Added invite list, ban list, some key management and connection
1941 error message printing to module formats in the Irssi SILC client.
1943 * Added new silc_client_set_away_message to set the away message
1944 that is back to the person who sent private message. The
1945 affected file lib/silcclient/silcapi.h and the
1946 lib/silcclient/client_prvmsg.c.
1948 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Fixed the private message sending in the Irssi SILC client,
1951 added local command KEY to the Irssi SILC client.
1953 Added key management and key agreement message formats to the
1954 irssi/src/fe-common/silc/module-formats.[ch].
1956 Added USERS (alias WHO) printing, server/router operator
1957 indication and LIST command printing to the module formats.
1959 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Fixed channel joining notify handling, cumode notify handling
1962 from Irssi SILC client.
1964 * Added SILC specific module-formats to the Irssi SILC client so
1965 that SILC specific message hilighting, colors etc is possible.
1966 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1968 Added channel mode, channel user mode, actions, notices,
1969 whois and whowas printing to the the module-formats.c.
1971 * Fixed a bug in channel deletion in the server. The channel
1972 is not left to the cache even if the channel founder auth mode
1973 is set when there are no users anymore on the channel. Affected
1974 file silcd/server.c.
1976 * The silc_net_localhost now resolves the entire hostname including
1977 the domain name. Affected file lib/silcutil/silcnet.c.
1979 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Changed the ask_passphrase client operation to be ascynchronous.
1982 It has now a completion callback and a context that the
1983 application must call after it has got the passphrase from
1984 the user. Affected files lib/silcclient/silcapi.h,
1985 lib/silcclient/protocol.c, lib/silcclient/command.c and
1988 Added SilcAskPassphrase callback that the application calls
1989 to deliver the passphrase to the library.
1991 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1992 The public key verification and especially a certificate
1993 verification is asynchronous procedure.
1995 Added new SILC_SKE_STATUS_PENDING status to indicate the
1996 request is pending and a callback will be called to finalize
1999 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2000 indicate that remote end did not send its public key (or
2001 certificate), even though we require it. Added check for this
2002 condition in the SKE. This was a security bug, now fixed.
2004 Defined new SilcSKEVerifyCbCompletion callback that is called
2005 when the verification process is completed.
2007 The affected files lib/silcske/silcske_status.h and
2008 lib/silcske/silcske.[ch].
2010 * Changed the verify_public_key client operation to be async
2011 as well. Defined SilcVerifyPublicKey callback that is used to
2012 indicate the success of the public key verification process.
2014 Changed the server and client to use the new async client
2017 * Changed the Irssi SILC client's internal scheduler to be called
2018 twice as many times as it used to be. As a result the client
2019 should be a bit faster now. Affected file is
2020 irssi/src/silc/core/silc-core.c.
2022 * Added support to Irssi SILC client of asynchronous public key
2023 verification and passphrase inquiry. Affected file is
2024 irssi/src/silc/core/silc-core.c.
2026 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * Do not say "You have left channel %s" in client library.
2029 Moved it to the application. Affected files are
2030 lib/silcclient/command.c and silc/client_ops.c.
2032 * Fixed silc_client_get_clients. Command context was not
2033 duplicated and was freed memory in the callback. Affected
2034 file lib/silcclient/idlist.c.
2036 * Do not say "you are now talking..." on JOIN command in the
2037 client library. The appliation must handle it.
2039 * Do not say ".. changed topic to" in command reply in the
2040 client libary. The application must handle it.
2042 * Fixed TOPIC command sending in the client library.
2044 * Fixed a memory leak in silc_client_command_free in the file
2045 lib/silcclient/command.c.
2047 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * Imported a modified version of Irssi client to the source tree.
2050 The Irssi will be used to create a new client called
2051 Irssi SILC. Imported to irssi/.
2053 Added silc_core_init_finish function to the Irssi. Affected
2054 file irssi/configure.in.
2056 A lot changes in the Makefile.ams around the irssi tree.
2058 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Do not rehash if the new size is same as the old size of the
2061 hash table, in the silc_hash_table_rehash*. The affected file
2062 lib/silcutil/silchashtable.c.
2064 * Replaced hash_table_del_by_context calls from the server
2065 (when channel->user_list and client->channels) to the
2066 hash_table_del as it is sufficient and faster.
2068 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Added silc_hash_table_list, silc_hash_table_get and the
2071 SilcHashTableList structure to provide an alternative way to
2072 traverse the hash table. The affected files are
2073 lib/silcutil/silchashtable.[ch].
2075 * Changed the server's idlist routines to use the hash table
2076 routines to optimize the code.
2078 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Replaced the client entry's `channel' list and channel entry's
2081 `user_list' list to hash tables for optimized lookup. Changed
2082 the code to use the hash table interface around the code.
2083 Affected file lib/silcd/idlist.[ch].
2085 * Added `auto_rehash' boolean argument to the function
2086 silc_hash_table_alloc to indicate whether the hash table should
2087 auto-rehash when it thinks is appropriate time. It will
2088 increase the hash table size if the there is twice as much
2089 entries in the table than the size of the table, and will
2090 decrease the size if there are twice as less entries than
2091 the size of the table.
2093 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2095 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2097 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * silc_idcache_purge_by_context deletes the entry now by context
2100 as it is supposed to do. Affected file lib/silccore/idcache.c.
2102 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2103 client is not anymore valid (WHOWAS givens the info) and not
2104 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2106 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Removed the `data' and `data_len' arguments from the ID Cache
2109 interfaces and added `name' argument. ID Cache does not handle
2110 anymore the binary data only a names associated with given ID.
2112 * When hashing a Client ID with silc_hash_id the entire ID is
2113 not hashed anymore, instead only the hash of the Client ID is
2114 hashed. This way we can access the Client ID from the cache
2115 with Client ID but with the hash of the ID (which is a hash of
2116 the nickname) as well without any difference in performance.
2118 Added also silc_idcache_find_by_id_one_ext to do one on one
2119 searching when we have the actual ID. Added also function
2120 silc_hash_client_id_compare. The affected files are
2121 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2123 * When hashing the name associated with a ID it is always done
2124 in lowercase. This way we can access the cache without worrying
2125 about case-sensitivity, even though, for example nicknames are
2128 * Fixed a bug in server with channel message sending. It put
2129 wrong ID type as destination ID. The affected file
2130 silcd/packet_send.c.
2132 * silc_idcache_del_by_context now deletes from all hash tables
2133 by context. Affected file lib/silccore/idcache.c.
2135 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2137 * Changed the client library to use the new ID Cache interface.
2138 Changes around the source tree.
2140 * Added silc_hash_table_rehash_ext to rehash with specific
2141 hash function. Affected file lib/silcutil/silchashtable.[ch].
2143 * Added silc_hash_string_compare to compare two strings in the
2144 hash table. Affected file lib/silcutil/silcutil.[ch].
2146 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Added new function silc_idcache_del_by_context into the
2149 lib/silccore/idcache.[ch].
2151 * Changed the server's ID list routines to use the new ID Cache
2152 interface. Changes around the source tree.
2154 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Added silc_hash_table_del[_by_context]_ext functions in to the
2157 lib/silcutil/silchashtable.[ch].
2159 Removed silc_hash_table_find_all* routines and added new
2160 silc_hash_table_find_foreach to replace them.
2162 Added silc_hash_table_replace_ext function as extended
2163 replacing function. Separated the simple hash table interface
2164 from the extended hash table interface in the file
2165 lib/silcutil/silchashtable.h.
2167 * Fixed minor bugs and changed it to use some of the new
2168 hash table functions in lib/silccore/idcache.c
2170 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Added new function silc_hash_table_find_all to return all keys
2173 in the hash table by the specified key. As the hash table is
2174 collision resistant it also makes it possible to have several
2175 duplicate keys in the hash table. This function may be used to
2176 find all of the keys from the hash.
2178 Added user_context arguments to the SilcHashFunction,
2179 SilcHashCompare and SilcHashDestructor to deliver user specified
2182 Added new fuctions silc_hash_table_find[_all]_ext to do
2183 extended lookup with specified hash and compare functions and
2184 specified user contexts.
2186 Added new function silc_hash_table_add_ext to add the key
2187 with specified hash function and user context.
2189 Added new function silc_hash_table_foreach to traverse all
2190 entrys in the hash table. Added SilcHashForeach callback
2193 Added new function silc_hash_table_del_by_context to delete
2194 the entry only if the context associated with the key matches.
2196 Affected files are lib/silcutil/silchashtable.[ch].
2198 * Removed silc_hash_[server/client/channel]_id and added just
2199 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2200 silc_hash_id_compare to compare two ID's using as the hash table
2201 comparison function. Added also silc_hash_data to hash
2202 binary data and silc_hash_data_compare to compare it.
2204 * Removed silc_idlist_find_client_by_hash as it is not needed
2205 anymore. Affected file silcd/idlist.[ch].
2207 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2208 to use internally the SilcHashTable. The new ID Cache is a lot
2209 faster than the old one. Some of the ID Cache interface was also
2210 rewritten and obsolete and stupid functions were removed.
2212 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Added entry_count field to the SilcHashTable to keep the number
2215 of the entries in the table. Implemented the function
2216 silc_hash_table_rehash. Added new function
2217 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2219 Fixed a minor bug in silc_hash_table_free.
2221 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2222 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2223 into the lib/silcutil/silcutil.[ch].
2225 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Implemented a collision resistant hash table into the
2228 lib/silcutil/silchashtable[ch]. See the header and the source
2229 for the SilcHashTable API.
2231 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Merged dotconf version 1.0.2 into lib/dotconf.
2235 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2237 * Do not compile anything in lib/silcsim/* if the SIM support
2238 is not enabled. The tree should now compile without problems
2241 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Compiled the SILC under cygwin. Compiled and tested briefly
2244 without problems. More tests needed. The SIMs didn't compile
2247 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2249 * Fixed possible crash in silc_get_username in the
2250 lib/silcutil/silcutil.c.
2252 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Fixed a va_arg in silc/client_ops.c.
2256 * Oops, RC5 routines were named AES and caused some problems
2257 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2259 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Added new SilcIDIP structure into the lib/silccore/id.h and
2262 replaced the old `ip' fields from all SILC ID's to that type.
2263 This is a step towards IPv6 support.
2265 The silc_id_get_len takes now the ID as an extra argument.
2266 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2267 both IPv4 and IPv6 based ID's.
2269 The affected files are lib/silccore/id.[ch] and other files
2270 around the tree using these routines.
2272 * Removed the ID length arguments in server from various
2273 silc_server_send_notify_* routines -> they are not needed
2276 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Fixed memory leak in silc_encode_pem_file in the file
2279 lib/silcutil/silcutil.c.
2281 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Check minor version as well in the SKE. Affected files are
2284 silcd/protocol.c and lib/silcclient/protocol.c.
2286 * Added --identifier option to the server so that an identifier
2287 can be when creating the public key for the server. Affected
2288 file is silcd/silcd.c.
2290 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2291 lib/silccrypt/silcpkcs.c.
2293 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Register default ciphers and stuff when using -C option with
2296 the server. Affected file sildc/silcd.c.
2298 * Put back the servers public key filename format, it is better
2299 than the new one. For now, the client keys are saved with the
2300 new filename format. The affected file silc/client_ops.c.
2302 * Implemented the Cipher API for the rest of the ciphers that
2303 did not implement it or implemented it the wrong way.
2305 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Register default ciphers and stuff when using the -S option
2308 in the client. Affected file silc/silc.c. Same also when
2309 creating new key pair with -C option.
2311 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Fixed the silc_verify_public_key client operation function to
2314 save the public keys differently. The fingerprint is now
2315 used as filename and not the hostname. This way also the
2316 client keys are saved uniquely and not with hostnames. The
2317 affected file is silc/client_ops.c.
2319 * Trimmed the silc_hash_fingerprint function to remove extra
2320 whitespaces from the end of the fingerprint. The affected
2321 file is lib/silccrypt/silchash.c.
2325 * Added silc_cipher_register_default function to register all
2326 default ciphers. It can be used when configuration files
2327 does not exist and the application does not want any specific
2328 ciphers in any specific order.
2330 The SilcDList is now used as silc_cipher_list dynamically
2331 allocated cipher list. Removed the static list all together
2332 and now all ciphers must be allocated to the dynamic list.
2333 The silc_cipher_alloc routine was changed to check only the
2336 All silc_cipher_* routines that used to return int returns
2339 The affected files lib/silccrypt/silccrypt.[ch].
2341 * The same thing was done to silc_hash_* as for silc_cipher_*
2342 routines. Affected files lib/silccrypt/silchash.[ch].
2344 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2345 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2346 Added also silc_pkcs_[un]register[_default] functions.
2347 Removed the data_context from the PKCS API.
2349 * Added silc_hmac_register_default function to register default
2350 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2351 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2352 to unregister all hmacs at once.
2354 * Register the default ciphers, hash functions, PKCSs and HMACs
2355 if client's configuration file does not exist. The affected
2358 * The client did not load the hash functions from the SIM
2359 modules at all. Added support for this. Affected file is
2360 silc/clientconfig.c.
2362 * When decoding public key with silc_pkcs_public_key_decode, check
2363 the supported algorithm only if PKCS are registered. Affected
2364 file lib/silccrypt/silcpkcs.c. The same was done with the
2365 silc_pkcs_private_key_decode.
2367 * Fixed the SILC List routines to keep the list always in order.
2368 It used to change the list's order when traversing the list but
2369 not it preserves the order. Affected file lib/trq/silclist.h.
2371 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Added the client library to use the SilcSocketConnection's
2374 reference counter (by silc_socket_dup) to prevent the bug that
2375 the socket object may be freed underneath async operation.
2377 * The name resolv library checking fixes in the configure.in.pre.
2380 * Created new version of the protocol drafts for future
2381 development. The -03 drafts are the ones that will be changed
2382 in the trunk now and the -02 will remain as they are.
2384 * Send list of CUMODE notifys to the router when announcing
2385 the channel users to the router. Affected file silcd/server.c.
2386 If the router receiving channel founder CUMODE for a channel
2387 that already has channel founder it will send CUMODE notify
2388 to the sender to remove the channel founder rights from the
2389 announced client. Affected file silcd/packet_receive.c.
2391 * The CUMODE notify may now use Server ID as well as the entity
2392 who changes the mode. Updated protocool specs.
2394 * Updated INSTALL and README files.
2396 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * New web pages in the http://silc.pspt.fi. The pages was
2403 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Implemented the [DenyConnectin] config section in the server.
2406 Added silc_server_config_denied_conn to check whether incoming
2407 connection is denied. Affected file silcd/serverconfig.[ch].
2409 * Do not check the ports when checking the incoming configuration
2410 data if the port is 0, meaning any. Affected file is
2411 silcd/serverconfig.c.
2413 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Fixed buffer overflow in silc_string_compare in the file
2416 lib/silcutil/silcutil.c.
2418 * Fixed double free in silc_server_command_leave in the file
2421 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Fixed the version checking in the server. Affected file is
2426 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Fixed the configuration data fetching when accepting new
2429 connections in the server. Affected file silcd/server.c.
2431 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Added `sender_entry' argument to the function
2434 silc_server_packet_relay_to_channel so that we can check
2435 whether some destination actually belongs to the same route
2436 the sender belongs (ie, we must not resend the packet to the
2437 sender). Affected file silcd/packet_send.[ch].
2439 * Added `servername' field to the SilcClientEntry in the server
2440 to hold the name of the server where client is from. Affected
2441 file is silcd/idlist.h.
2443 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Moved the channel message encrypting in the router betwen
2446 router connections from silc_server_channel_message to the
2447 silc_server_packet_relay_to_channel since we want to check
2448 whether we have anybody channel before encrypting anything.
2449 Affected files silcd/packet_[receive/send].c.
2451 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Fixed the [AdminConnection] server config section to support
2454 multiple entries. Affected file silcd/serverconfig.c.
2456 * Added support into the server to check the validity of the
2457 incoming connection before executing any KE or authentication
2460 * The connection configuration is now saved to the KE and
2461 connection auth protocol contexts and not fetched anymore in
2462 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2464 * The local hosts listenning address and port is also resolved
2465 now when starting the server. We want to have the socket object
2466 to include the real address and port for the listener. Added
2467 new function silc_net_check_local_by_sock into the files
2468 lib/silcutil/silcnet.[ch].
2470 * Fixed a broadcast bug in server -> do not broadcast if we
2473 * Fixed a routing bug. Do not route broadcast packets ever.
2474 Broadcast packets must be processed always and not routed since
2475 they may be destined to some other host than yourself and thus
2476 would get routed without no good reason. Affected file is
2479 * Added function silc_server_config_is_primary_route to check
2480 whether primary router connection has been configured (a router
2481 configuration that we are initiating). If there is not, we
2482 will assume that there is only two routers in the SILC network
2483 and we will use the incoming router connection as our primary
2484 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2486 * Changed the order of the broadcasting. Broadcast _after_ the
2487 packet has been processed not before. Affected file is
2490 * Fixed a [ClientConnection] parsing bug. The port was never
2491 parsed correctly thus resulting to port 0. Affected file
2492 silcd/serverconfig.c.
2494 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2495 argument and did not set the broadcast packet flag. Affected
2496 file silcd/packet_send.c. Fixed same bug in the function
2497 silc_server_send_notify as well.
2499 * If we receive NEW_ID packet for our own ID in the server, ignore
2502 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Removed the nickname from the Private Message Payload.
2507 Updated the code and the protocol specs.
2509 * Updated protocol specs for submitting to the IETF.
2511 * Tweaked the Random Number Generator a bit. Affected file
2512 lib/silccrypt/silcrng.c. Exported a new function
2513 silc_rng_[global]_add_noise which can be used to add more
2516 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Do not parse packets with different timeout when protocol
2519 is active -> may cause problem with rekey. Affected file
2522 * When server receives signoff notify it must not create
2523 new channel key if the client is on any channels since the
2524 sender of the signoff notify will create it.
2526 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Added printing of error messages during SKE protocol from the
2529 failure packet sent by server during SKE. Affected file
2532 * Removed the client's failure_callback handling with timeout
2533 and handle it immediately when received.
2535 * The SKE library returned wrong type in SUCCESS and FAILURE
2536 packets. They must be 32 bit MSB not 16 bit MSB.
2538 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Ok, rewrote the logic of the re-key and now it seems to work.
2541 I tested it on high traffic with frequent re-keys without
2542 problems. Added hmac_receive (and renamed hmac to hmac_send)
2543 in SilcClientConnection in lib/silcclient/client.h and
2544 in SilcIDListData in silcd/idlist.h. Also, removed the
2545 SilcPacketParserContext's cipher and hmac fields as they are
2546 not needed anymore and actually caused some problems when
2547 the ciphers and hmac's changed underneath the packet parser.
2549 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * If re-key protocol is active then process the incoming packets
2552 synchronously since we must assure that icoming packets encrypted
2553 with the old key is processed before the new keys is set to
2554 use. This is true other packets than for REKEY packets.
2555 Affected file silcd/server.c. The same was done to client library
2556 as well, affected file lib/silcclient/client.c.
2558 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Fixed bug in client and server to accept the force send if
2561 the packet is send from silc_[server/client]_packet_process
2562 function. Otherwise the packets are never delivered, oops.
2564 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Disable force sending of packets when REKEY protocol is active.
2567 We must assure that no packet is sent directly when rekey is
2568 performed. All packets must be sent through packet queue.
2569 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2570 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2571 function is silc_[server/client]_packet_send_real to check
2574 * Replaced the SIM paths from example config files to
2575 /usr/local/modules. Also, make install creates now
2576 /usr/local/silc/logs directory to hold all the SILC server
2579 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Made the configure.in.pre work on Solaris. Patch by salo.
2583 * Made all ciphers compatible with non-x86 machines. Defined
2584 CBC mode macros into lib/silccrypt/ciphers_def.h.
2586 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Fixed the make install.
2590 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * When MAC computation fails the silc_packet_decrypt returned 0
2593 even though it was supposed to return -1. Fixed this. The
2594 affected file is lib/silccore/silcpacket.c.
2596 * Do not replace the config files in /etc/silc (in make install)
2597 if they already exist. Affected file ./Makefile.am.
2599 * Do not send re-key packets immediately but through packet queue.
2600 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2602 * Changed silc_net_check_host_by_sock to return FALSE if the
2603 IP/DNS could not be resolved. Though, it returns the IP address
2604 now even if it could not resolve it (but returns also FALSE).
2605 Affected file lib/silcutil/silcnet.[ch].
2607 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Added silc_pkcs_decode_identifier to decode the public key's
2610 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2611 Added also silc_pkcs_free_identifier. Added also new context
2612 SilcPublicKeyIdentifier.
2614 * Added -S option to the silc client. It is used to dump the
2615 contents of the specified public key file.
2617 * Changed the PKCS api to return the public key length when
2618 setting the public key.
2620 * Fixed a fatal bug in the public and private key file loading.
2621 Affected file lib/silccrypt/silcpkcs.c.
2623 * Execute the packet parsing for client with zero (0) timeout
2624 if the protocol is active. Affected file silcd/server.c.
2626 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Made the key generation options to the silcd program. Added
2629 -C option, equivalent to client's option.
2631 * Added new [ServerKeys] config section to the server. It
2632 configures the server's public and private key.
2634 * Defined generic Public Key Payload into the protocol
2635 specification to send specific type of public keys and
2638 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2639 public key or certificate.
2641 * Implemented the GETKEY command to the server and to the
2642 client library and on user interface.
2644 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Made preliminary `make install' work.
2648 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Added SilcServerRekey context into silcd/idlist.h.
2652 * Added the PFS support as defined in the specification to the
2653 SKE protocol. Affected files lib/silcske/*.c.
2655 * Added `ske_group' field to the SilcServerRekey context to hold
2656 the number of the SKE group that is used with PFS in re-key.
2657 Affected file silcd/idlist.h.
2659 * Added PFS re-key support to the server. Affected file is
2662 * Added silc_protocol_cancel to cancel execution of the next
2663 state of the protocol. Affected file is
2664 lib/silccore/silcprotocol.[ch].
2666 * Added the re-key support with and without PFS to the client
2667 library. Re-key is performed once in an hour, by default.
2669 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2670 Added silc_client_rekey_callback and silc_client_rekey_final.
2671 Affected files are lib/silcclient/protocol.[ch] and
2672 lib/silcclient/client.[ch].
2674 * Removed the `hmac_key' and `hmac_key_len' fields from the
2675 SilcClientConnection structure; not needed. Affected file is
2676 lib/silcclient/client.h.
2680 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Do not ask whether user wants to use the negotiated private key
2683 for private messages, just use it. Affected file is
2684 silc/local_command.c.
2686 * Added `send_enc_key' and `enc_key_len' fields to the
2687 SilcIDListData structure since they are needed in the re-key
2688 phase. Affected file is silcd/idlist.[ch].
2690 * Implemented the simple re-key protocol into the server.
2691 Affected files silcd/server.c and silcd/protocol.[ch]. The
2692 re-key will be performed once in an hour, by default.
2694 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2695 Added silc_server_rekey, silc_server_rekey_callback and
2696 silc_server_rekey_final.
2698 * Removed Tunneled flag from the protocol. Updated the code
2699 and the specifications.
2701 * Adde `pfs' field to the SilcIDListData to indicate whether
2702 the PFS is to be performed in the re-key. Affected file is
2705 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2708 int64 of at least the xintXX size. If void * is less that 4
2709 bytes uint32 * will be used. Defined bool as boolean.
2711 * Changed _ALL_ unsigned long and unsigned int to uint32,
2712 unsgined short to uint16 in the source tree.
2714 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2715 not handle clients that has entry->data.registered == FALSE.
2716 They are not in the network anymore. Affected file is
2719 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Implemented the sending of the SERVER_SIGNOFF notify in the
2722 server. Affected file is silcd/server.c.
2724 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2725 Added also silc_notify_payload_encode_args into the
2726 lib/silccore/silcnotify.[ch].
2728 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2729 Affected file silcd/packet_receive.c.
2731 * Implemented the SERVER_SIGNOFF notify handling in the client
2732 library. Affected file lib/silcclient/client_notify.c. Also,
2733 implemnted the printing of the SERVER_SIGNOFF info to the
2734 application. Affected file silc/client_ops.c.
2736 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2737 if the deleting was successful. Affected file silcd/idlist.[ch].
2739 * Added support for public key authentication in the connection
2740 authentication protocol in the client library. Affected file
2741 lib/silcclient/protocol.c.
2743 * Changed the server's silc_idlist_get_clients_by_* interface
2744 to support already allocated array so that new entries may be
2745 added to pre-allocated array. Affected file silcd/idlist.[ch].
2746 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2747 and command replies.
2749 * All command reply functions in the server now calls the
2750 pending command callback even if error occured. This way the
2751 error will be delivered to the client as well. Affected files
2752 silcd/command.c and silcd/command_reply.c.
2754 * Fixed INFO command to return local server's info if no server
2755 was provided. Affected file lib/silcclient/command.c.
2757 * Removed RESTART command for good. Updated the code and the
2760 * Rewrote parts of the task system. It is a bit simpler now.
2761 Removed unsued task priorities. The affected files are
2762 lib/silcutil/silctask.[ch].
2764 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Moved the USERS printing from the library to the application.
2767 Affected files lib/silcclient/command.c and silc/client_ops.c.
2769 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Added channel key re-key support. The re-key is perfomed
2774 only by the router and is done once in an hour. Added `rekey'
2775 field to the SilcChannelEntry in the server. Affected files
2776 silcd/server.c and silcd/idlist.h.
2778 * Added silc_task_unregister_by_context into the file
2779 lib/silcutil/silctask.[ch].
2781 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Added SILC_UMODE_GONE mode to indicate when the client is not
2784 present in the SILC network. Added also support to the local
2785 command AWAY that will set this mode. Added support of showing
2786 "xxx is gone" in WHOIS command. The USERS command shows the
2787 gone status as well.
2789 * Fixed setting server and router operator privileges in the
2790 server's UMODE command. Affected file silcd/command.c.
2792 * Merged the SKE KE1 and KE2 payloads into one payload. The
2793 new KE payload is equivalent to the old KE2 payload.
2795 Cleaned up the SKE Start Payload parsing. It now uses the
2796 simple buffer unformatting to do the parsing. A lot faster
2799 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2800 to the SKE that is used to indicate whether both of the SKE
2801 parties should perform authentication. By default only the
2802 responder performs authentication. By setting this flag also
2803 the initiator must do authentication. By default it is unset
2804 since in normal SKE case, client to server connection, only
2805 the responder should do authentication. When doing SKE between
2806 two clients both should perform authentication. Updated the
2807 code and the protocol specs.
2809 * A little fix to IDENTIFY command in the server. Search the
2810 client first by hash not nickname. Affected file is
2813 * Fixed the silc_client_close_connection to support closing
2814 the client to client connections wihtout deleting too much
2815 data. Affected file lib/silcclient/client.c.
2817 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2818 are received if protocol used to be active but is not anymore
2819 the application would crash due to NULL pointer dereference.
2820 Affected files silcd/server.c and lib/silcclient/client.c.
2822 * Added `hash' field to the SilcClientConnection to include
2823 the hash function negotiated in the SKE protocol.
2825 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2826 to set the channel founder authentication data. A client can
2827 claim the founder rights later by providing the authentication
2828 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2829 This way the channel founder can regain the channel founder
2830 privileges even it is left the channel. This works only on
2831 local server and the client must be connected to the same
2832 server to be able to regain the founder rights. Updated the
2833 protocol specs accordingly.
2835 Added support to the CMODE command in the client to set the
2836 founder auth data. Read the README to see how to set it.
2838 Added support to the CUMODE command to claim the founder
2839 rights. Read the README to see how to do it.
2841 Added support for the founder authentication to the Channel
2842 Entry in the server. Affected file silcd/idlist.h.
2844 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2845 server's CMODE command. Affected file silcd/command.c.
2847 * Added the following new functions into lib/silccore/silcauth.[ch]:
2848 silc_auth_get_method and silc_auth_get_data.
2850 * The server now saves the remote hosts public key to the
2851 SilcIDListData pointer. Affected file silcd/protocol.c.
2853 * The normal server now does not remove the channel entry from
2854 the cache if the founder authentication data is set. It used
2855 to remove it if the founder was the last one on the channel on
2856 the server and left the channel. The auth data is saved and
2857 if the channel is re-joined later the old entry is used with
2858 the old auth data. Affected files silcd/command_reply.c and
2861 * Removed the `pkcs' field from the SilcIDListData structure
2862 in the server; it is not used. Affected file silcd/idlist.h.
2864 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Fixed packet processing on slow links. Partial packets were
2867 never re-processed because the incoming data buffer was cleared
2868 by the application. Application must not directly clear the
2869 sock->inbuf, the packet processing routines handle it. Fixed
2870 this in client library and in server.
2872 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Fixed the WHOIS and IDENTIFY send reply function to really
2875 check whether to send list or just one entry. Affected file
2878 * Cleaned up the LEAVE command's channel key distribution. The
2879 affected file silcd/command.c.
2881 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2882 can enforce the channel mode as well. In that case the ID
2883 includes the ID of the server. The code now enforces the
2884 mode change if the router have different mode than the server.
2886 * The notify client operation with CMODE_CHANGE notify can now
2887 return NULL client_entry pointer if the CMODE was not changed
2888 by client. Application must check for this.
2890 * Added <Server ID> argument to INFO command to support server
2891 info fetching by Server ID.
2893 * Added silc_server_announce_get_channel_users to get assembled
2894 packets of channel users of the specified channel. Affected
2895 file silcd/server.[ch].
2897 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2898 was freed underneath the ID Cache.
2900 * Re-announce clients when the server received CHANNEL_CHANGE
2901 notify from the router. Affected file silcd/packet_send.c.
2903 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2906 crashed since it did not handle the fact that there is no cipher
2907 called "3" and didn't check the error condition. Now fixed.
2909 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2910 flag. It can be used to send message requests.
2912 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Implemented the RESTART command in the client.
2916 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2917 notice type messages. Added notice printing to the user
2920 * The channel keys are not re-generated if the channel's mode
2921 is PRIVKEY, ie private key on the channel exists. Affected
2922 files silcd/server.c and silcd/command.c.
2924 * Fixed a little bug in channel message delivery when channel
2925 private keys are set in the server. Affected file is
2926 silcd/packet_send.c.
2928 * Changed the setting on channel->on_channel = TRUE from the
2929 silc_client_save_channel_key to the JOIN command reply. The
2930 key payload is not received if the private channel key is set.
2931 Affected file lib/silcclient/command_reply.c and the
2932 lib/silcclient/client_channel.c.
2934 * When the CMODE_CHANGE notify is sent and the channel private
2935 key mode is removed the channel key must be re-generated in
2936 other cells as well. Added this support for the router in the
2937 silcd/packet_receive.c.
2939 * Added new local command NOTICE to send notice message on
2940 channel. Affected file silc/local_command.[ch].
2942 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Added new local command ME to the client. It is used to send
2945 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2946 some action. Affected file silc/local_command.[ch].
2948 * Changed channel_message and private_message client operations
2949 to deliver the message flags to the application. Added also
2950 the `flags' arguments to the silc_client_send_channel_message
2951 and silc_client_send_private_message functions. Affected file
2954 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Redefined the Private Message Payload to support private message
2957 keys and to support the new private message flags. Updated
2958 the protocol specs. Flags makes it possible to have for example
2959 CTCP style messages.
2961 * Added new type SilcPrivateMessagePayload and defined an API
2962 for it in the lib/silcclient/silcprivate.[ch].
2964 * Tested private message private keys successfully. Tested the
2965 private message key set, unset and list commands with the new
2968 * Redefined the Channel Message Payload to include the channel
2969 message flags (equal with private message flags) to support
2970 for example CTCP style messages.
2972 * Defined some of the message (for channel and private message)
2973 flags. Updated the protocol specs and added the flags to the
2974 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2976 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Added SilcKeyAgreementStatus type to the key agreement routines
2979 to indicate the current status and error if one occured.
2980 The status types are defined in the lib/silcclient/silcapi.h.
2982 * Added new local command KEY that is used to set and unset private
2983 keys for channels, set and unset private keys for private messages
2984 with remote clients and to send key agreement requests and
2985 negotiate the key agreement protocol with remote client. The
2986 key agreement is supported only to negotiate private message keys,
2987 it currently cannot be used to negotiate private keys for channels,
2988 as it is not convenient for that purpose.
2990 * Fixed a minor pending callback setting bug in the function
2991 silc_client_get_client_by_id_resolve, now the function works.
2992 Affected file lib/silcclient/idlist.c.
2994 * Added function silc_net_get_local_port to get local bound
2995 port by socket. Added to lib/silcutil/silcnet.[ch].
2997 * Added `sockets' and `sockets_count' fields to the SilcClient
2998 object. They hold the sockets of the listenning sockets in
2999 the client. Listenning sockets may be for example the key
3000 agreement server. Affected file lib/silcclient/client.[ch].
3001 Added functions the silc_client_add_socket and the
3002 silc_client_del_socket. They are exported to the application
3005 * Added ~./silc/clientkeys to support other client's public keys.
3007 * Renamed verify_server_key client operation to verify_public_key
3008 and added one argument to indicate the type of the connection
3009 (server, client etc.).
3011 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Added silc_server_connection_auth_request to handle the
3014 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3015 silcd/packet_receive.[ch].
3017 * Added silc_server_send_connection_auth_request into the
3018 silcd/packet_send.c to send the connection auth request packet.
3020 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3023 * Fixed the public key authentication in responder side in the
3024 server. The `auth_data' pointer includes the SilcPublicKey
3025 not the path to the public key. Affected file silcd/protocol.c.
3027 * Implemented the public key authentication in the initiator side
3028 in the server. Affected file silcd/protocol.c.
3030 * Removed the [RedirectClient] config section from the server
3031 configuration. Is not needed and I don't want to implement it.
3033 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Cleaned up the CMODE command in the server. It now works
3036 correctly and supports all the modes defined in the protocol.
3037 Affected file is silcd/command.c.
3039 * Added `hmac_name' field to the SilcChannelEntry in the server
3040 to hold the default HMAC of the channel. It can be set when
3041 creating the channel (with JOIN command). Affected files
3044 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3045 type to indicate the change of the current cipher and hmac
3046 on the channel. Client can safely ignore the <cipher> argument
3047 (if it chooses to do so) since the CHANNEL_KEY packet will
3048 force the channel key change anyway. The <hmac> argument is
3049 important since the client is responsible of setting the new
3050 HMAC and the hmac key into use.
3052 * Fixed the CMODE command in the client library as well.
3054 * Tested CMODE command in router environment successfully.
3056 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Show the version of the remote client (or server) when connecting
3059 to the server. It is logged to the log file. Affected file
3060 is silcd/protocol.c.
3062 * Fixed the KILLED notify handling in the client library. The
3063 client must be removed from all channels when receiving the
3066 Also, do not remove the client entry when giving the KILL
3067 command but when the KILLED notify is received.
3069 * Removed silc_idlist_find_client_by_nickname from the server.
3070 Not needed anymore. Affected files silcd/idlist.[ch].
3072 * Implemented the CHANNEL_CHANGE notify type handling to the
3073 server. Affected file silcd/server.c.
3077 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Added silc_server_send_notify_invite to send the INVITE
3080 notify between routers.
3082 * Implemented the INVITE command correctly to the server.
3084 * Implemented the INVITE notify type handling in the server.
3086 * Implemented the INVITE command to the client library and on the
3089 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Added function silc_server_get_client_resolve to find the
3092 client entry by ID from all ID lists and then resolve it
3093 (using WHOIS) if it cannot be found. Affected file is
3096 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Implemented the BAN command to the client library.
3100 * The JOIN command in the server now checks the invite list
3103 * Changed the silc_command_reply_payload_encode_va and the
3104 silc_command_payload_encode_va to support that if argument is
3105 NULL it ignores and checks the next argument. Affected file
3106 lib/silccore/silccommand.c.
3108 * Added silc_server_send_notify_ban to send the BAN notify
3109 type between routers.
3111 * Chaned the silc_notify_payload_encode to support that if
3112 argument is NULL it ignores and checks the next argument.
3113 Affected file lib/silccore/silcnotify.c.
3115 * Tested ban lists in router environment successfully.
3117 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Implemented BAN command to the server, in silcd/command.[ch].
3121 * Removed the BAN and INVITE_LIST modes from the CMODE command
3124 * Added function silc_string_match to regex match two strings.
3125 Affected files lib/silcutil/silcutil.[ch].
3127 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Redefined parts of the SilcChannelEntry in the server to support
3130 the new ban and invite lists.
3132 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Redefined the INVITE command. The same command can be used to
3135 invite individuals to the channel but also to manage the invite
3136 list of the channel (to add to and remove from the invite list).
3137 Updated the protocol specs.
3139 * Added new command SILC_COMMAND_BAN that can be used to manage
3140 the ban list of the channel. Updated the protocol specs.
3142 * Removed the channel modes: the SILC_CMODE_BAN and the
3143 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3144 in the CMODE command. The equivalent features are now available
3145 using INVITE and BAN commands. Updated the protocol specs.
3147 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3148 in the network about change in the current ban list. The notify
3149 type is not used by the client.
3151 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3152 support the invite lists.
3154 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Added new function silc_string_regexify that converts string
3157 including wildcard characters into regex string that can
3158 be used by the GNU regex library. Added into the file
3159 lib/silcutil/silcutil.[ch].
3161 Added silc_string_regex_combine to combine to regex strings
3162 into one so that they can be used as one regex string by
3163 the GNU regex library. Added into the file
3164 lib/silcutil/silcutil.[ch].
3166 Added silc_string_regex_match to match two strings. It returns
3167 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3169 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Imported GNU regex to the soruce tree into lib/contrib.
3172 Fixed some compiler warning from the regex.c.
3174 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Fixed MOTD command in the server to work in router environment.
3178 * Fixed the MOTD command in the client library to support
3179 the server argument in the command.
3181 * Added `nickname_len' argument to the silc_idlist_add_client
3182 in the server, as the `nickname' argument may be binary data
3185 * Added silc_idlist_get_channels to return all channels from
3188 * Implemented LIST command to the server. Affected file is
3191 * Implemented the LIST command to the client library and on the
3194 * Added [<user count>] argument to the LIST command reply.
3195 With private channels the user count is not shown.
3197 * Updated TODO and README.
3199 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * The client entry's data.registered must be TRUE even with
3202 global client entry on global client list. The data.registered
3203 is used to check whether the client is anymore in the network,
3204 for example with WHOWAS command so it must be valid.
3206 * Fixed the WHOWAS command in the server. It now actually works
3207 in router environment. Added function into silcd/command_reply.c
3208 silc_server_command_reply_whowas_save.
3210 * Added silc_idlist_purge function to the silcd/idlist.c
3211 to periodically purge the ID Cache.
3213 * Fixed INFO command in the server. It works now in router
3214 environment. Added <server name> argument to the INFO command
3215 reply. Updated the protocol specs.
3217 * Fixed minor bug in silc_idcache_purge to not purge if the
3218 expire value is zero.
3220 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3221 they were buggy because of the WHOWAS information.
3223 * Fixed local command MSG to handle the async resolving of
3224 the remote client properly. It used to fail the first MSG.
3225 Affected file silc/local_command.c.
3227 * Added `data_len' field to SilcIDCache context.
3229 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Update TODO. Todo in commands in the server.
3233 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3236 used by routers as broadcast packet to inform other routers
3237 about the changed user mode.
3239 Implemented the notify handling in the server. Affected file is
3240 silcd/packet_receive.c. Added the function
3241 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3243 * Added new generic Channel Payload and deprecated the New Channel
3244 Payload. The New Channel Payload is now the generic Channel
3247 * Added new argument `mode' to the silc_server_send_new_channel
3248 as it is required in the Channel Payload now.
3250 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3251 and created a new and real SilChannelPayload to represent the
3252 new generic Channel Payload. Implemented the encode/decode
3253 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3255 * Added silc_server_get_client_channel_list to return the list
3256 of channels the client has joined for WHOIS command reply.
3257 Affected file silcd/server.[ch].
3259 * Implemented the channel list sending in the WHOIS command reply
3260 in server and in the client.
3262 Implemented the channel list displaying on the user interface
3263 as well. Affected file silc/client_ops.c.
3265 * Added silc_channel_payload_parse_list to parse list of Channel
3266 Payloads. It returns SilcDList list of SilcChannelPayloads.
3267 Client for example can use this function to parse the list of
3268 channels it receives in the WHOIS command reply. The caller
3269 must free the list by calling silc_channel_payload_list_free.
3270 Affected files lib/silccore/silcchannel.[ch].
3272 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Added one new argument <user mode> to the WHOIS command reply
3275 to return the mode of the user in SILC. Updated the protocol
3278 Implemented it to the server and client.
3280 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Fixed the mode printing on the user interface on joining.
3283 Affected file silc/client_ops.c.
3285 * Implemented the UMODE command and user modes in general to the
3286 client library and to the user interface.
3288 * Implemented the UMODE command to the server.
3290 * The server now sends UNKNOWN_COMMAND error status if client sends
3291 unknown command. Affected file silcd/command.c.
3293 * All server commands now handle the command identifier the right
3294 way when sending the command reply to the client. The client can
3295 use to identify the command replies with the identifier.
3297 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added silc_server_get_client_route to resolve the route to
3300 the client indicated by the client ID. Affected file is
3303 * Added silc_server_relay_packet as general function to relay
3304 packet to arbitrary destination. This deprecates functions
3305 like _send_private_message_key, _relay_notify etc. Affected
3306 file is silcd/packet_send.[ch].
3308 Removed silc_server_send_key_agreement,
3309 silc_server_send_private_message_key and
3310 silc_server_packet_relay_notify functions from the file
3311 silcd/packet_send.[ch].
3315 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3316 server. Affected file silcd/packet_receive.[ch].
3318 * Implemented the KILL command to the client. Implemented the
3319 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3320 Affected files lib/silcclient/command[_reply].c and
3321 lib/silcclient/client_notify.c. Implemented the KILL notify
3322 printing in the user inteface.
3324 * Fixed a lot silc_parse_nick memory leaks from the client
3325 library in the file lib/silcclient/command.c.
3327 * Changed the silc_server_send_notify_on_channels's `sender'
3328 argument from SilcSocketConnection to SilcClientEntry to
3329 check the sender as entry and not as connection object and not
3330 to send to the client provided as argument. The affected file
3331 is silcd/packet_send.[ch].
3333 * The notify packets that are destined directly to the client used
3334 to not to be processed by the server. Now changed that and the
3335 server processes all notify packets. After relaying the packet
3336 to the client the notify packet is processed in the server.
3338 * The silc_server_free_client_data now checks whether there is
3339 pending outgoing traffic for the client and purges the data to
3340 the network before removing the client entry.
3342 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3345 an client is killed from the SILC Network. Updated the protocol
3348 Added new function silc_server_send_notify_killed to the
3349 silcd/packet_send.[ch].
3351 * Added function silc_server_packet_relay_notify to relay notify
3352 packets that are destined directly to a client. In this case
3353 the server does not process the notify packets but merely relays
3354 it to the client. Affected file silcd/packet_send.[ch].
3356 Added also silc_server_packet_process_relay_notify to check
3357 whereto relay the notify. Affected file is
3358 silcd/packet_receive.[ch].
3360 * Implemented the KILL command to the server.
3364 * Added the backup schema desgined last fall to the protocol
3365 specs for everyone to see. The specification is in the
3366 *-spec-xx.txt draft and the packet type definitions for the
3367 backup routers is in *-pp-xx.txt draft. Thusly, added also
3368 new packet type SILC_PACKET_CELL_ROUTERS.
3370 * A big security problem in the implementation discovered. The
3371 signoff of an client did not cause new channel key generation
3372 which it of course should've done. The channel keys must be
3373 always re-generated when client leaves (or signoffs) the channel.
3374 The silc_server_remove_from_channels funtion now handles
3375 the channel key re-generation.
3377 * Added `sender' argument to the silc_server_send_notify_on_channels
3378 to not to send the client provided as argument. Affected file
3379 silcd/packet_send.[ch].
3381 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Implemented OPER and SILCOPER commands into the server and
3386 * Added silc_auth_verify and silc_auth_verify_data to verify
3387 the authentication directly from the authentication payload.
3388 It supports verifying both passphrase and public key based
3389 authentication. Affected file lib/silccore/silcauth.[ch].
3391 * Added `hash' field to the SilcIDListData structure. It is the
3392 hash negotiated in the SKE protocol. Affected file is
3395 * Slight redesigning of the SilcAuthPayload handling routines.
3396 Do not send SilcPKCS but SilcPublicKey as argument.
3398 * Implemented the public key authentication support to the
3399 serverconfig. The public key is loaded from the provided path
3400 and saved as authentication data to void * pointer. Thus,
3401 changed the unsigned char *auth_data to void *auth_data;
3403 * Fixed SHUTDOWN command to send the reply before the server
3404 is shutdown. :) Affected file silcd/command.c.
3406 * Fixed fatal bug in CONNECT command. The hostname was invalid
3407 memory and server crashed. Affected file silcd/command.c.
3409 * Fixed fatal bug in CLOSE command. The server_entry became
3410 invalid but was referenced later in the command. Affected file
3413 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Fixed fatal bug in failure packet handling. Server ignored
3416 the failure and thus crashed when it came.
3420 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3423 that the command may be executed only once in (about) 2 seconds.
3424 The old SILC_CF_LAG flag is same but allows command bursts up
3425 to five before limiting.
3427 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3428 server code. Various commands now includes the CF_LAG_STRICT
3429 flag to disallow any kind of miss-use of the command.
3431 * Fixed the silc_buffer_unformat to not to allocate any data
3432 if the length of the data is zero. It used to allocate the
3433 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3435 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Changed the format of AdminConnection configuration section
3438 in the server. Added username of the admin to the format.
3439 Affected files silcd/serverconfig.[ch].
3441 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3442 to return admin configuration data by host, username and/or
3445 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Implemented WHOWAS command to the server. Added the functions:
3449 silc_server_command_whowas_parse,
3450 silc_server_command_whowas_send_reply,
3451 silc_server_command_whowas_from_client and
3452 silc_server_command_whowas_from_server
3454 * Added <Client ID> argument to the WHOWAS command reply. Updated
3455 the protocol specs accordingly.
3457 * Implemented WHOWAS command and command_reply to the client
3460 Implemented the WHOWAS printing on the user interface.
3462 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Added new argument to the WHOWAS command reply, the real name.
3465 It is an optional argument. Updated the protocol specs.
3467 * Added SilcIDCacheDestructor callback that is registered when
3468 the SilcIDCache is allocated. The callback is called when
3469 an cache entry in the ID Cache expires, or is purged from the
3470 cache. Added into lib/silccore/idcache.[ch].
3472 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3473 to destruct the client entries when the cache entry expires.
3474 Other ID Cache's in server and in the client library ignores
3477 * If the ID Cache entry's `expire' field is zero then the entry
3478 never expires. Added boolean `expire' argument to the
3479 silc_idcache_add function in the lib/silccore/idcache.[ch].
3480 If it is TRUE the default expiry value is used.
3482 * Added silc_server_free_client_data_timeout that is registered
3483 when client disconnects. By default for 5 minutes we preserve
3484 the client entry for history - for WHOWAS command.
3486 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Added support to the server to enforce that commands are not
3489 executed more than once in 2 seconds. If server receives
3490 commands from client more frequently, timeout is registered
3491 to process the commands. Affected file silcd/command.c.
3492 Added new function silc_server_command_process_timeout.
3494 * Changed NICK_NOTIFY handling in client library to check that
3495 if the client's nickname was changed, so there is no need to
3496 resolve anything from the server.
3498 * Removed error printing from the WHOIS and IDENTIFY commands.
3499 If error occurs then it is ignored silently in the client library.
3500 The application, however, may map the received error to
3501 human readable error string. The application currently maps
3502 the NO_SUCH_NICKNAME error to string.
3504 * Made the command status message public to the application. Moved
3505 them from lib/silcclient/command_reply.c to
3506 lib/silcclient/command_reply.h. The application can map the
3507 received command status to the string with the
3508 silc_client_command_status_message function.
3510 * Added check to the server to check that client's ID is same
3511 as the Source ID in the packet the client sent. They must
3514 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Added dist-bzip hook to the Makefile.am to make bzip2
3517 compressed distributions.
3519 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Server now enforces the maximum length for the nickname and
3522 the channel as protocol specification dictates. 128 bytes for
3523 nickname and 256 bytes for channel name.
3525 * Moved the WHOIS printing to the application. The client libary
3526 does not print out the WHOIS information anymore, the application
3527 must do it. Renamed silc_client_command_reply_whois_print to
3528 the silc_client_command_reply_whois_save.
3530 The client's idle time is also sent to the application now, and
3531 the idle is shown on screen.
3533 * Added silc_client_command_reply_identify_save to save the
3534 received IDENTIFY entries.
3536 * Do not check for channel private keys in message sending and
3537 reception if the channel does not have the PRIVKEY mode set.
3538 Affected file lib/silclient/client_channel.c.
3540 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3543 just surfaced after chaning the JOIN procedure.
3545 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added silc_client_get_clients_by_list to get client entries
3548 from Client ID list, that is returned for example by JOIN
3549 and USERS command replies. The application should use this
3550 function for example when JOIN command reply is received to
3551 resolve the clients already on the channel (library does not
3552 do that anymore as USERS command reply is not used in the JOIN
3553 procedure anymore). Affected files lib/silcclient/silcapi.h and
3554 lib/silcclient/idlist.c.
3556 * JOIN command reply and USERS command reply returns now SilcBuffer
3557 pointers instead of unsigned char pointers when returning
3558 the client list and mode list.
3560 * Added <Client ID> argument to the JOIN command reply, mainly
3561 for the server to identify for which client the command was
3562 originally sent. Updated protocol specs accordingly.
3564 * Added SilcDlist private_key pointer to the SilcChannelEntry
3565 in the client to support the channel private keys. Affected
3566 file is lib/silcclient/idlist.h.
3568 * Added SilcChannelPrivateKey argument to the function
3569 silc_client_send_channel_message so that application can choose
3570 to use specific private ke if it wants to. If it is not provided,
3571 the normal channel key is used, unless private keys are set.
3572 In this case the first (key that was added first) is used
3573 as the encryption key.
3575 * Implemented the support for channel private key handling.
3576 Implemented the following functions:
3578 silc_client_add_channel_private_key,
3579 silc_client_del_channel_private_keys,
3580 silc_client_del_channel_private_key,
3581 silc_client_list_channel_private_keys and
3582 silc_client_free_channel_private_keys
3584 Affected file lib/silcclient/client_channel.c.
3586 * Added the support for the private keys in the channel message
3587 sending and encryption and in the message reception and
3588 decryption. Affected funtions are
3589 silc_client_send_channel_message and silc_client_channel_message.
3591 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Added SKE's key verify callback to the client library's
3594 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3596 * Removed the statement that server (or router) must send USERS
3597 command reply when joining to the channel so that the client
3598 knows who are on the channel. Instead, the client list and
3599 client's mode list is now sent in the JOIN command reply to the
3600 client who joined channel. This is better solution.
3602 * Added function silc_server_get_users_on_channel and function
3603 silc_server_save_users_on_channel to the silcd/server.[ch].
3605 * Removed function silc_server_command_send_users from the
3608 * Do not show topic on the client library anymore. The topic is
3609 sent in the command reply notify to the application and the
3610 application must show the topic now.
3612 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added client searching by nickname hash into the IDENTIFY and
3615 WHOIS commands in the server as they were clearly missing from
3616 them. Affected file is silcd/command.c.
3618 * Fixed a bug in private message receiving in the client library.
3619 The remote ID was freed and it wasn't supposed, now it is
3622 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Minor fix to the channel payload; allocate the data area, as it
3625 needs to be of specific length.
3627 * If the key agreement port is zero then the operating
3628 system will define the bound port. Affected files are
3629 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3631 * Added new function silc_channel_payload_decrypt into the file
3632 lib/silccore/silcchannel.[ch].
3634 * Moved the channel message etc, check from silc_packet_decrypt
3635 to applications. The library calls now a generic
3636 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3637 when the packet is either normal or special. This was done to
3638 allow more wide range of checking that was not allowed when
3639 the code was in library. Now applications can do virtually any
3640 checks to the packet and return to the library the decision how
3641 the packet should be processed. Affected files are
3642 lib/silccore/silcpacket.[ch].
3644 Added silc_server_packet_decrypt_check to the server and
3645 silc_client_packet_decrypt_check to the client library.
3647 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3648 to send with specified source and destination information.
3650 * Channel message delivery between routers was broken after the
3651 channel key distribution was fixed earlier. The channel key
3652 was used be to distributed to other routers as well which is not
3653 allowed by the protocol. Now this is fixed and channel keys
3654 really are cell specific and the channel message delivery between
3655 routers comply with the protocol specification.
3657 * Fixed various commands in server to check also the global list
3658 for the channel entry and not just the local list. The affected
3659 file silcd/command.c.
3661 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Added assert()s to buffer formatting and unformatting routines
3664 to assert (if --enable-debug) when error occurs. Affected
3665 file: lib/silcutil/silcbuffmt.c.
3667 * Changed to auto-reconnect to check whether the remote host is
3668 router and register the re-connect timeout if it is. It used
3669 to check that whether we are normal server, but router must do
3670 auto-reconnect with another router as well. Affected file
3673 * Removed the [<key len>] option from CMODE command as the cipher
3674 name decides the key length, nowadays. See the defined ciphers
3675 from the protocol specification.
3677 * Added [<hmac>] option to the CMODE command to define the HMAC
3678 for the channel. Added SILC_CMODE_HMAC channel mode.
3680 * Added [<hmac>] option for the JOIN command so that user can
3681 select which HMAC is used to compute the MACs of the channel
3684 * Added Hmac field to the Channel Message Payload. The integrity
3685 of plaintext channel messages are now protected by computing
3686 MAC of the message and attaching the MAC to the payload. The
3687 MAC is encrypted. Now, it is clear that this causes some
3688 overhead to the size of the packet but rationale for this is that
3689 now the receiver can verify whether the channel message decrypted
3690 correctly and also when private keys are set for the channel the
3691 receiver can decrypt the packet with several keys and check from
3692 the MAC which key decrypted the message correctly.
3694 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3695 lib/silccrypt/silccipher.[ch].
3697 * Added silc_hash_len to return the digest length into the
3698 lib/silcrypt/silchash.[ch].
3700 * Rewrote parts of Silc Channel Payload interface in the
3701 lib/silccore/silcchannel.[ch]. The encode function now also
3702 encrypts the packet and parse function decrypts it.
3704 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Fixed a minor formatting bug in the SKE's key material processing.
3707 It actually might have processed the keys wrong way resulting
3710 * Redefined the mandatory HMAC algorithms and added new algorithms.
3711 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3712 and hmac-md5 truncated to 96 bits. The mandatory is now
3713 hmac-sha1-96. Rest are optional (including the one that used
3714 to be mandatory). Rationale for this is that the truncated HMAC
3715 length is sufficient from security point of view and can actually
3716 make the attack against the HMAC harder. Also, the truncated
3717 HMAC causes less overhead to the packets. See the RFC2104 for
3720 * Added new [hmac] configuration section. The SKE used to use
3721 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3722 is of course wrong. The official names that must be proposed in
3723 the SKE are the ones defined in the protocol specification
3724 (hmac-sha1-96 for example). The user can configure any hmac
3725 using any hash function configured in the [hash] section. At
3726 least, the mandatory must be configured.
3728 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3730 * Added HMAC list to the SKE proposal list. It has now both
3731 hash algorithm list and HMAC list. This makes the protocol
3732 incompatible with previous versions. The SKE now seems to work
3733 the way it is supposed to work, for the first time actually.
3735 * Defined plain Hash algorithms to the protocol specification.
3738 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Implemented support for key agreement packets into the server.
3741 Added functions silc_server_key_agreement and
3742 silc_server_send_key_agreement. Other than these functions,
3743 server has nothing to do with this packet.
3745 * Added support for private message key packets into the server.
3746 Added functions silc_server_private_message_key and
3747 silc_server_send_private_message_key.
3751 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3752 called in the protocol's final callback instead in the END
3753 protocol state. This makes a little more sense and in the same
3754 time in client we can use the same protocol routines for normal
3755 key exchange and to key agreement packet handling as well.
3757 * Added to both client's and server's KE protocol context the
3758 SilcSKEKeyMaterial pointer to save the key material. We will
3759 bring the key material to the protocol's final callback by doing
3760 this. The final callback must free the key material.
3762 * Added SKE's packet_send callback into client's KE protocol
3763 context so that the caller can choose what packet sending function
3764 is used. This way we can use different packet sending when
3765 doing normal SKE when doing key agreement packet handling (in
3766 the key agreement packet handling we do not want to encrypt
3769 * Implemented the responder side of the key agreement routines
3770 in the client. The client can now bind to specified port and
3771 accept incoming key negotiation. The key material is passed
3772 to the application after the protocol is over.
3774 * Implemented the processing of incoming Key Agreement packet
3775 in the client. Added function silc_client_key_agreement to
3778 * Implemented the intiator side of the key agreement routines
3779 in the client. The client can now initiate key agreement with
3780 another remote client. The key material is passed to the
3781 application after the protocol is over.
3783 * Created client_keyagr.c to include all the key agreement
3786 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3787 SILC_TASK_CALLBACK except that it is not static.
3789 * Created client_notify.c and moved the Notify packet handling
3790 from the client.[ch] into that file.
3792 * Created client_prvmsg.c and moved all private message and
3793 private message key routines from the client.[ch] into that file.
3795 * Create client_channel.c and moved all channel message and
3796 channel private key routines from the client.[ch] into that file.
3798 * Changed silc_client_get_client_by_id_resolve to resolve with
3799 WHOIS command instead of IDENTIFY command, in the file
3800 lib/silclient/idlist.c.
3802 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Implemented the SKE's responder side to the Client library.
3806 * When FAILURE is received to the protocol do not trust it
3807 blindly. Register a timeout to wait whether the remote closes
3808 the connection as it should do it, only after that process the
3809 actual failure. This was changed to both client and server.
3811 * Added client_internal.h to include some of the structures
3812 there instead of client.h in lib/silcclient/.
3814 * Added function silc_task_unregister_by_callback to unregister
3815 timeouts by the callback function.
3817 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Some "Incomplete WHOIS info" errors has been appearing on the
3820 log files. Took away the entry->userinfo check from WHOIS
3821 reply sending. The entry->userinfo is now " " if client did not
3822 provide one. I thought this was fixed earlier but something
3823 is wrong still. Let's see if the error still appears.
3825 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Fixed a minor bug in the login when the channel key is
3828 re-generated in the server. It used to generate the key in
3829 wrong order and thus caused problems in the channel traffic.
3831 * Fixed a minor bug in channel key distsribution after
3832 KICK command. The key was not sent to the router even though
3835 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Added silc_ske_process_key_material_data as generic routine
3838 to process any key material as the SILC protocol dictates. The
3839 function is used by the actual SKE library but can be used by
3840 applications as well. This relates to the private message keys
3841 and the channel private keys since they must be processed the
3842 same way the normal SILC session keys. The protocol dictates
3843 this. Affected files: lib/silcske/silcske.[ch].
3845 Added also silc_ske_free_key_material to free the
3846 SilcSKEKeyMaterial structure.
3848 * Defined silc_cipher_set_key function to set the key for
3849 cipher without using the object's method function. The affected
3850 files: lib/silccrypt/silccipher.[ch].
3852 * Implemented silc silc_client_add_private_message_key,
3853 silc_client_add_private_message_key_ske,
3854 silc_client_del_private_message_key,
3855 silc_client_list_private_message_keys and
3856 silc_client_free_private_message_keys functions in the
3859 Added functions silc_client_send_private_message_key to send
3860 the Private Message Key payload and silc_client_private_message_key
3861 to handle incoming Private Message Key payload.
3863 * Added Cipher field to the Private Message Key payload to set
3864 the cipher to be used. If ignored, the default cipher defined
3865 in the SILC protocol (aes-256-cbc) is used.
3867 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Removed lib/silcclient/ops.h file.
3871 Redefined parts of the SILC Client Library API. Created new
3872 file silcapi.h that deprecates the ops.h file and defines the
3873 published Client Library API. Defined also private message key
3874 API and channel private key API into the file.
3876 This is the file that the application must include from the
3877 SILC Client Library. Other files need not be included by
3878 the application anymore.
3880 * Added new key_agreement client operation callback and also
3881 defined the Key Agreement library API for the application.
3883 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3886 is used by clients to request key negotiation between another
3887 client in the SILC network. If the negotiation is started it
3888 is performed using the SKE protocol. The result of the
3889 negotiation, the secret key material, can be used for example
3890 as private message key.
3892 Implemented the Key Agreement payload into the files
3893 lib/silccore/silauth.[ch].
3895 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Redefined ciphers for the SILC protocol. Added some new ciphers
3898 and defined the key lengths for the algorithms. Changed the
3899 code accordingly. The default key length is now 256 bits.
3901 * Fixed SKE key distribution function silc_ske_process_key_material
3902 when the key length is more than 128 bits. The default key
3903 length in SILC is now 256 bits.
3905 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3906 to indicate unsupported algorithm.
3908 * Renamed rijndael.c to aes.c and all functions as well.
3910 * Fixed a long standing channel key setting bug in client library.
3911 Weird that it has never surfaced before.
3913 * Fixed bug in channel deletion. If the entire channel is removed
3914 then it must also delete the references of the channel entry
3915 from the client's channel list as the client's channel entry and
3916 the channel's client entry share same memory.
3918 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Implemented CONNECT and SHUTDOWN commands in the client.
3922 * Implemented CLOSE command to the client.
3924 * Added the function silc_idlist_find_server_by_name into the
3925 files silcd/idlist.[ch].
3927 Added the function silc_idlist_find_server_by_conn into the
3928 files silcd/idlist.[ch].
3930 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * DIE command was renamed to SHUTDOWN. Updated the both code
3935 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3936 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3938 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3941 * Added function silc_server_create_connection function to create
3942 connection to remote router. My server implementation actually
3943 does not allow router to connect to normal server (it expects
3944 that normal server always initiates the connection to the router)
3945 so the CONNECT command is only good for connecting to another
3948 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3951 or some other client was kicked from the channel.
3953 Implemented the handling of the notify type to both client
3956 Implemented silc_server_send_notify_kicked to send the KICKED
3957 notify. It is used to send it to the server's primary router.
3959 * Implemented the KICK command into server and client.
3961 * Added `query' argument to the silc_idlist_get_client function
3962 to indicate whether to query the client from server or not if
3965 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3966 to indicate that the client is not channel founder.
3970 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Removed the rng context from SilcPacketContext structure and
3973 changed that the packet routine uses the Global RNG API.
3975 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Added support for quit message that client can "leave" on the
3978 channel when it quits the SILC. It is ditributed inside the
3979 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3981 Added silc_server_free_client_data that will take the
3982 signoff message as argument.
3984 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3986 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Updated parts of the protocol specification to keep it up
3991 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3994 payloads in one packet.
3996 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3997 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3998 use now the new List flag.
4000 * Also deprecated the following packet types: REPLACE_ID,
4001 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4003 * Added list support for Notify packet in server.
4005 * Added silc_server_send_notify_channel_change to send the
4006 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4007 the silc_server_send_replace_id.
4009 * Added silc_server_send_notify_nick_change to send the
4010 NICK_CHANGE notify type. Deprecates the function
4011 silc_server_send_replace_id.
4013 * Added silc_server_send_notify_join to send the JOIN notify type.
4014 Deprecates the function silc_server_send_new_channel_user.
4016 * Added silc_server_send_notify_leave to send LEAVE notify type.
4017 Deprecates the function silc_server_send_remove_channel_user.
4019 * Added silc_server_send_notify_cmode and
4020 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4021 types. Deprecates the silc_server_send_set_mode function.
4023 * Added SERVER_SIGNOFF notify type to indicate that server has
4024 quit. This means that all clients on the channel from that
4025 server will drop. This can be also used when netsplit happens.
4027 Deprecated REMOVE_ID packet type since it is not needed anymore
4030 Added silc_server_send_notify_server_signoff to send the
4031 SERVER_SIGNOFF notify type. Deprecates the function
4032 silc_server_send_remove_id.
4034 Added also silc_server_send_notify_signoff to send the
4035 SIGNOFF notify type.
4037 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4038 SILC protocol from this day on. Changed the protocol
4039 specification as well.
4041 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4042 notify type. It is used between routers to notify about
4043 topic changes on a channel.
4045 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4048 * Partly updated the protocol specification to comply with the
4049 changes now made. It is still though a bit outdated.
4051 * The JOIN notify type now takes one extra argument <Channel ID>.
4052 The packet used to be destined to the channel but now the
4053 JOIN type may be sent as list thus it is impossible to
4054 destine it to any specific channel. By adding this argument
4055 it is again possible.
4057 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Added CREDITS file. The CHANGES and CREDITS file will appear
4060 in the distribution as well.
4062 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4065 types in the server's silcd/packet_receive.c.
4067 * Implemented CMODE and CUMODE to work in router environment.
4069 * Fixed minor encoding and decoding buglet from the
4070 lib/silccore/silcmode.c.
4072 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4075 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4077 * Changed all SilcConfigServer* and silc_config_server* to
4078 SilcServerConfig* and silc_server_config*, respectively.
4081 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Associated the ID (client or server ID) to the Authentication
4084 Payload to avoid any possibility of forging. Updated the
4085 protocol specification and the code accordingly.
4087 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * The RSA key length is now save to the RsaKey context in the
4090 key generation process in lib/silccrypt/rsa.c. The key length
4091 is now used to figure out the maximum size of the block allowed
4092 to be encrypted/signed.
4094 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4095 is equivalent to the silc_mp_mp2bin but does not allocate any
4098 * Changed silc_mp_mp2bin API to take length argument. If it is
4099 non-zero then the buffer is allocated that large. If zero, then
4100 the size is approximated using silc_mp_sizeinbase, which however
4103 * Created Global RNG API which is global RNG that application can
4104 initialize. After initializing, any routine anywhere in the
4105 code (including library) can use RNG without allocating a new
4106 RNG object. This was done to allow this sort of use of the
4107 RNG in code that has no chance to allocate RNG object. All
4108 applications currently allocate this and many routines in the
4109 library use this. Affected file lib/silccrypt/silcrng.[ch].
4111 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4112 it to use the Global RNG API.
4114 * Defined Authentication Payload into protocol specification that
4115 is used during SILC session to authenticate entities. It is
4116 used for example by client to authenticate itself to the server
4117 to obtain server operator privileges.
4119 Implemented this payload into the lib/silccore/silcauth.[ch].
4120 Implemented also routines for public key based authentication
4121 as the new protocol specification dictates.
4123 Moved definitions of different authentication methods from
4124 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4126 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4127 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4128 silc_pkcs_verify_with_hash functions into the file
4129 lib/silccrypt/silcpkcs.[ch].
4131 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * The client entry's userinfo pointer must be always valid.
4134 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4135 will fail since it requires the userinfo. Now, the userinfo
4136 is allocated as "" if actual userinfo does not exist. Actually,
4137 it must exist and it is totally Ok to drop client connections
4138 that does not announce the userinfo. However, we will make
4139 this workaround for now.
4141 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4142 to return the remote port by socket.
4144 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4147 SILC_SERVER_PENDING_EXEC and added an new macro
4148 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4149 data or when error occurs while processing the pending command.
4151 Added new argument `destructor' into silc_server_command_pending
4152 and to the SilcServerCommandPending object. This destructor is
4153 now called after calling the pending callback or if error occurs
4154 immediately. If error occurs the actual pending callback won't
4155 be called at all - only the destructor. The destructor may be
4156 NULL if destructor is not needed.
4158 All this applies for client library code as well. Similar
4159 changes were made there as well for the pending commands.
4161 In the client, the application must now allocate the
4162 SilcClientCommandContext with the silc_client_command_alloc
4165 * Added reference counter to the SilcServerCommandContext. Added
4166 function silc_server_command_alloc and silc_server_command_dup
4169 Same type of functions added to the client library for the same
4172 * Removed the cmd_ident from IDListData away since it is now
4173 global for all connections. It is the command identifier used
4174 in command sending and with pending commands. The affected file
4177 * Added reference counter to the SilcSocketConnection objecet to
4178 indicate the usage count of the object. The object won't be
4179 freed untill the reference counter hits zero. Currently only
4180 server uses this, and client ignores it. The client must be
4181 set to use this too later. The affected files are
4182 lib/silccore/silcsockconn.[ch]. Added also the function
4183 silc_socket_dup to increase the reference counter.
4185 This was mainly added because it is possible that the socket
4186 is removed underneath of pending command or other async
4187 operation. Now it won't be free'd and proper DISCONNECTING
4188 flags, etc. can be set to avoid sending data to connection that
4189 is not valid anymore.
4191 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4192 the connection. After that it sets SILC_SET_DISCONNECTED.
4193 It is, however, possible that the socket data is not still freed.
4194 The silc_server_packet_process now checks that data is not
4195 read or written to connection that is DISCONNECTED. The socket
4196 get's freed when the reference counter hits zero.
4198 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Changed the client operation API: channel_message operation's
4201 `sender' is now the client entry of the sender, not the nickname
4202 and the `channel' is the channel entry, not the channel name.
4204 In the private_message operation the `sender' is now also the
4205 client entry of the sender not the nickname.
4207 Affected file is lib/silcclient/ops.h and all applications
4208 using the client operations.
4210 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Moved the calling of ops->connect() from connect_to_server_final
4213 into receive_new_id functin since that is the point when the
4214 client is actually allowed to send traffic to network. The
4215 affected file is lib/silcclient/client.c.
4217 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4220 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4221 (if needs broadcasting) instead of broadcasting the packets one
4222 by one which would make a burst in the network traffic.
4224 * Added `broadcast' argument to the functions in silcd/server.[ch]
4225 silc_server_create_new_channel[_with_id] to indicate whether
4226 to send New Channel packet to primary router.
4228 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added new function into the silcd/server.[ch] files:
4231 silc_server_create_new_channel_with_id to create new channel with
4232 already existing Channel ID.
4234 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4235 lib/silccore/silcpacket.h. This packet is used t send list of
4236 Set Mode payloads inside one packet. Server uses this to set
4237 the modes for the channels and clients on those channels, that it
4238 announced to the router when it connected to it. The protocol
4239 specification has been updated accordingly.
4241 * The silc_server_new_channel did not handle the packet coming
4242 from normal server as it normally does not send that. However,
4243 when it announces its channels it does send it. Implemented
4244 the support for that.
4246 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4247 into the file lib/silccore/id.h.
4249 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Fixed memory leaks in the functions silc_idlist_del_client,
4252 silc_idlist_del_channel and silc_idlist_del_server in the file
4253 silcd/idlist.c. All of those leaked like a sieve.
4255 * Fixed some small memory leaks in the client's function
4256 silc_client_notify_by_server.
4258 * Added functions into silcd/server.c: silc_server_announce_clients,
4259 silc_server_announce_channels and silc_server_announce_server.
4260 These functions are used by normal and router server to announce
4261 to its primary router about clients, channels and servers (when
4262 router) that we own. This is done after we've connected to the
4265 These functions effectively implements the following packet types:
4266 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4267 and SILC_PACKET_NEW_ID_LIST.
4269 * Added new functions into the silcd/packet_receive.[ch]:
4270 silc_server_new_id_list, silc_server_new_channel_list and
4271 silc_server_new_channel_user_list to handle the incoming
4272 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4274 * Added support of changing Channel ID in the function
4275 silc_server_replace_id. If the server that announces a channel
4276 to the router already exists in the router (with same name but
4277 with different Channel ID), router is responsible to send
4278 Replace ID packet to the server and force the server to change
4279 the Channel ID to the one router has.
4281 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4282 client that the Channel ID has been changed by the router. The
4283 normal server sends this to the client. Client must start using
4284 the new Channel ID as the channel's ID.
4286 Implemented handling of this new type into lib/silcclient/client.c
4287 into the function silc_client_notify_by_server.
4289 * Added new function silc_idlist_replace_channel_id into the files
4290 silcd/idlist.[ch] to replace the Channel ID.
4292 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Call silc_server_command_identify_check always when processing
4295 the IDENTIFY command in silcd/command.c
4297 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4300 send keepalive packets. The packet can be sent by clients,
4301 servers and routers.
4303 Added function silc_socket_set_heartbeat into the file
4304 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4305 If not set, the heartbeat is not performed. The actual
4306 heartbeat is implemented in the low level socket connection
4307 library. However, application is responsible of actually
4310 Added silc_server_send_heartbeat to send the actual heartbeat
4311 packet into silcd/packet_send.[ch]. Server now performs
4312 keepalive with all connections.
4314 * Added silc_task_get_first function into lib/silcutil/silctask.c
4315 to return the timeout task with shortest timeout. There was a bug
4316 in task unregistration that caused problems. TODO has been
4317 updated to include that task system must be rewritten.
4319 * The client library will now resolve the client information when
4320 receiving JOIN notify from server for client that we know but
4321 have incomplete information.
4323 * Rewrote parts of silc_server_remove_from_channels and
4324 silc_server_remove_from_one_channel as they did not remove the
4325 channel in some circumstances even though they should've.
4327 * Encryption problem encountered in server:
4329 The LEAVE command used to send the Channel Key packet to the
4330 router immediately after generating it. However, the code
4331 had earlier sent Remove Channel user packet but not immediately,
4332 ie. it was put to queue. The order of packets in the router
4333 was that Channel Key packet was first and Remove Channel User
4334 packet was second, even though they were encrypted in the
4335 reverse order. For this reason, MAC check failed. Now, this
4336 is fixed by not sending the Channel Key packet immediately but
4337 putting it to queue. However, this is more fundamental problem:
4338 packets that are in queue should actually not be encrypted
4339 because packets that are sent immediately gets encrypted
4340 actually with wrong IV (and thus MAC check fails). So, packets
4341 that are in queue should be encrypted when they are sent to
4342 the wire and not when they put to the queue.
4344 However, the problem is that the current system has not been
4345 designed to work that way. Instead, the packet is encrypted
4346 as soon as possible and left to the queue. The queue is then
4347 just purged into wire. There won't be any fixes for this
4348 any time soon. So, the current semantic for packet sending
4351 o If you send packet to remote host and do not force the send
4352 (the packet will be in queue) then all subsequent packets to the
4353 same remote host must also be put to the queue. Only after the
4354 queue has been purged is it safe again to force the packet
4357 o If you send all packets immediately then it safe to send
4358 any of subsequent packets through the queue, however, after
4359 the first packet is put to queue then any subsequent packets
4360 must also be put to the queue.
4362 Follow these rules and everything works fine.
4364 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Added new function silc_server_remove_clients_by_server to
4367 remove all client entries from ID list when the server connection
4368 is lost. In this case it is also important to invalidate all
4369 client entires as they hold the invalid server entry. This
4370 fixes fatal bug when server has lost connection and will reconnect
4373 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Made some sanity checks to silc_server_daemonise like to check
4376 whether the requested user and group actually exists.
4378 * Added sanity check to SKE's silc_ske_responder_finish to check
4379 that the public and private key actually is valid.
4381 * Invalidate the client's nickname when receiving Replace ID
4382 packet and the Client ID is being replaced. This means that the
4383 server will query the nickname if someone needs it (client)
4386 * Sort the ID Cache in client library when the ID Cache data
4387 has changed (needs sorting).
4389 * Do not allow for SILC client to create several connections to
4390 several servers. The client does not support windows right now
4391 and generating multiple connections causes weird behaviour.
4393 Irssi-silc client does support windows and can handle several
4394 connections without problems, see: www.irssi.org and SILC plugin.
4396 * Fixed some places where client was added to the IDList. The
4397 rule of thumb is following (in order to get everything right):
4398 If the client is directly connected local client then the
4399 `connection' argument must be set and `router' argument must be
4400 NULL to silc_idlist_add_client function. If the client is not
4401 directly connected client then the `router' argument must
4402 bet set and the `connection' argument must be NULL to the
4403 silc_idlist_add_client function.
4405 * The funtion silc_server_packet_send_local_channel actually did
4406 not check whether the client was locally connected or not. It
4407 does that now. Fixed a bug related to LEAVE command.
4409 * Fixed Remove Channel User payload parsing bug in server's
4410 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4412 * The server's silc_server_save_channel_key now checks also the
4413 global ID list for the channel as it might not be in the local
4414 list. Fixed a bug related to LEAVE command.
4416 * Is this the end of the [<unknown>] buglet that has been lurking
4417 around for a long time? A little for loop fix in server's
4418 silc_server_command_whois_parse that is used by both IDENTIFY
4419 and WHOIS command. At least, this was a clear bug and a cause
4420 of one type of [<unknown>] buglet.
4422 * WHOIS and IDENTIFY commands call the function
4423 silc_server_command_[whois/identify]_check function even if
4424 we are not router server.
4426 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Added --with-gmp configuration option. If set the GMP
4429 is always compiled in the SILC source tree. If not set then
4430 it is checked whether the system has the GMP3 installed. If
4431 it has then the GMP won't be compiled (the system's headers
4432 and library is used), if it doesn't have it then the GMP is
4433 compiled in the SILC source tree.
4435 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Changed RSA private exponent generation to what PKCS #1
4438 suggests. We try to find the smallest possible d by doing
4439 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4440 not security fix but optimization.
4442 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Added new config entry [Identity] to fork the server and run
4445 it as specific user and group. A patch from Bostik.
4447 * Imported Dotconf configuration library into lib/dotconf.
4448 This will be used to create the SILC configuration files later.
4449 It will appear in the distsribution after this commit.
4451 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * A big code auditing weekend happening. Auditing code for
4454 obvious mistakes, bugs and errors. Also, removing any code
4457 Removed files for being obsolete:
4459 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4460 inline in the file lib/silcutil/silcbuffer.h)
4462 o lib/silcutil/silcbufutil.c (the header has inline versions)
4464 Changed code to fix possible error conditions:
4466 o The buffer formatting routines now check that the destination
4467 buffer really has enough space to add the data. This applies for
4468 both buffer formatting and unformatting
4469 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4470 unformatting was changed to accomodate following rules:
4471 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4472 sent to the function while XXX_*STRING will not allocate or copy
4473 the data into the buffer. Instead it sets the pointer from the
4474 buffer into the pointer sent as argument (XXX_*STRING used to
4475 require that the pointer must be allocated already). This change
4476 makes this whole thing a bit more consistent and more optimized
4477 (note that the data returned in the unformatting with XXX_*STRING
4478 must not be freed now). The routines return now -1 on error.
4480 o Tried to find all code that use buffer_format and buffer_unformat
4481 and added return value checking to prevent formatting and
4482 especially unformatting errors and possible subsequent fatal
4485 o Changed ske->x and ske->KEY to mallocated pointers in
4486 lib/silcske/silcske.h. Fixed possible data and memory leak.
4488 o Added return value checking to all *_parse* functions. Fixed
4489 many memory leaks as well.
4491 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4492 so that buffer overflows would not happen. All code now also
4493 checks the return value as it can fail.
4495 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Added reconnection support to server if the normal server looses
4498 its connection to the router (for example if router is rebooted).
4499 The server performs normal reconnection strategy implemented
4500 to the server. Affected file silcd/server.c.
4502 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added new packet type SILC_PACKET_SET_MODE that is used to
4505 distribute the information about changed modes (for clients,
4506 channels and clients channel modes) to all routers in the
4507 network. Updated the protocol specification accordingly.
4509 Added functions into silcd/packet_send.c and
4510 silcd/packet_receive.c: silc_server_send_set_mode,
4511 silc_server_set_mode.
4513 Added new files silcmode.[ch] into lib/silccore that implements
4514 the encoding and decoding of Set Mode Payload. Added new type
4515 SilcSetModePayload. Moved the definitions of different modes
4516 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4518 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Oops, a little mistake in server's connection authentication
4521 protocol. The protocol is not ended with FAILURE but with
4522 SUCCESS if the authentication is Ok. :) Affected file is
4525 * Implemented NICK_CHANGE notify handling in server in the file
4526 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4527 the local clients on the channel. After the changing nickname
4528 in router environment snhould work and the [<unknown>] nickname
4529 should appear no more.
4531 The silc_server_replace_id function that receives the Replace ID
4532 payload now sends the NICK_CHANGE notify type also in the file
4533 silcd/packet_receive.c
4535 * Changed WHOIS and IDENTIFY command to support the maximum amount
4536 of arguments defined in protocol specs (3328 arguments). This
4537 fixed a bug that caused problems when there were more than three
4540 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added extra parameter, command identifier, to the
4543 silc_client_send_command so that explicit command identifier
4546 Changed that ID list routines uses specific command identifier
4547 when sending WHOIS/IDENTIFY requests to the server so that they
4548 can be identified when the reply comes back.
4550 Affected files lib/silcclient/command.[ch],
4551 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4553 * Added `sender' argument to silc_server_packet_send_to_channel
4554 to indicaet the sender who originally sent the packet to us
4555 that we are now re-sending. Ignored if NULL. Affected file
4556 silcd/packet_send.[ch].
4558 * Added some server statistics support in silcd/server_internal.h
4559 SilcServerStatistics structure and around the server code. Also
4560 send some nice statistics information when client is connecting
4563 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Fixed channel ID decoding in server's JOIN command reply in
4566 silcd/command_reply.c
4568 * Fixed braodcasting of replace ID payload to not to send it if
4569 we are standalone server in silcd/packet_receive.c.
4571 * Fixed all channel message sending routines to not to send
4572 packets to clients that has router set, since they are routed
4573 separately in the same function earlier. Affects file
4574 silcd/packet_send.c and all channel packet sending functions.
4576 * In USERS reply, res_argv[i] are not allocated, the table
4577 is allocated. Thus changed that free the table, not its
4580 * In server's whois_check and identify_check if the client is
4581 locally connected do not send any WHOIS commands - they are not
4584 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Fixed some minor bugs in client when sending WHOIS command. The
4587 arguments was in wrong order.
4589 * Removed statis function add_to_channel from server in
4590 silcd/command.c that was previously used with the joining but
4593 * Tested USERS command in router environment successfully with two
4594 routers, two servers and two clients.
4596 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Reorganized the USERS command and command reply in client library
4599 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4600 When the command is given by user we register a pending command
4601 callback that will reprocess the command after the reply has been
4602 received from the server. When reprocessing the packet we then
4603 display the information. Thus, the USERS information is displayed
4604 now in the command callback instead of in the command reply
4605 callback. The processing of the command is same as previously
4606 when server has sent the command reply in the JOINing process.
4608 * Added to USERS command in silcd/command_reply.c to join the client,
4609 we didn't use to know about, to the channel after we've created
4610 a client entry for it. Also, for clienet we did know already still
4611 check whether it is on the channel or not and add it if not.
4613 * Removed silc_server_command_join_notify as the function and its
4616 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Changed the client's pending command handling to the same as the
4619 server's pending command handling. It is also now possible to
4620 execute command reply functions from other command reply
4621 function as the function callbacks for commands and command
4622 replies are one and same. The pending commands are not static
4623 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4624 in client connection context. Thus, pending commands are server
4625 connection specific as it is convenient.
4627 Changed the function silc_client_command_pending and
4628 silc_client_command_pending_del and added new function
4629 silc_client_command_pending_check. Removed the
4630 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4633 * Added cmd_ident, current command identifier, to the client
4634 connection context in lib/silcclient/client.h to keep track on
4635 command identifiers used in command sending. Client's command reply
4636 function handling now supports the mandatory command identifiers.
4638 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4639 funtions in client to fully support pending command callbacks.
4641 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4642 as one of the arguments to the application in the command reply
4645 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4646 before first releasing SILC but came back. Now it is removed again
4647 and should come back nomore. The FORWARDED flag was used only
4648 by the JOINing procedure by forwarding the command packet to router.
4649 Now, the JOINing procedure has been changed to more generic (due
4650 to various router environment issues) and FORWARDED is not needed
4651 anymore for anything. The protocol specification is yet to be
4654 Now, removed silc_server_packet_forward from server and the flag
4655 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4657 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Renamed NAMES command to USERS command. The NAMES was named that
4660 due to historical reasons. Now it is renamed. Also, rewrote
4661 parts of the USERS command. The nickname list is not sent anymore
4662 by the server. Only Client ID and mode lists are sent in the USERS
4663 command. Changed this also to the protocol specification.
4665 The client now resolves the names and stuff after it receives
4666 the USERS list from the server when joining to the channel.
4668 * WHOIS and IDENTIFY commands has been changed to support multiple
4669 Client ID's per command. One can now search for multiple users
4670 in the network by sending only one WHOIS or IDENTIFY command.
4671 Changed the code and the protocol specifications.
4673 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4674 uses silc_server_command_whois_parse to parse the request. */
4676 * If normal server, do not parse the WHOIS and IDENTIFY requests
4677 before sending it to the router. Saves some time.
4679 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Fixed JOIN command on client library. Wrong number of arguments
4682 used to crash the client.
4684 * Added silc_server_channel_has_global function to check whether
4685 channel has global users or not.
4687 * Added silc_server_channel_has_local function to check whether channel
4688 has locally connected clients on the channel.
4690 * The silc_server_remove_from_one_channel now checks whether the
4691 channel has global users or not after given client was removed from
4692 the channel. It also checks whether the channel has local clients
4693 on the channel anymore. If it does not have then the channel entry
4694 is removed as it is not needed anymore.
4696 * The silc_server_notify now checks on JOIN notify whether the joining
4697 client is one of locally connected or global. If it is global then
4698 the channel has now global users on the channel and that is marked
4699 to the channel entry. Also, it now saves the global client to
4700 global list who is joining and JOINs it to the channel. This is
4701 for normal server, that is.
4703 Changed silc_server_send_notify_on_channel,
4704 silc_server_packet_relay_to_channel and
4705 silc_server_packet_send_to_channel check if we are normal server
4706 and client has router set (ie. global client) do not send the
4707 message to that client, as it is already routed to our router.
4709 * Implemented LEAVE notify type handling in silc_server_notify
4712 * Tested LEAVE command in router environment successfully. Tested
4713 with two routers, two servers and two clients.
4717 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4719 * Implemented SIGNOFF notify type handling in silc_server_notify
4722 * silc_server_remove_id now removes the client entry from all channels
4723 it has joined and thusly sends SIGNOFF notify type.
4725 * Rewrote the NAMES list generation in server by removing two excess
4726 loops. The lists are created now inside one loop.
4728 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * silc_server_remove_channel_user checks now also global list
4731 for channel and client.
4733 * silc_server_new_channel_user checks now both local and global
4734 list for channel and client. Fixed a bug in client id decoding.
4735 Used to decode wrong buffer.
4737 * silc_server_channel_message checks now both local and global
4738 list for channel entry.
4740 * Tested channel joining (hence JOIN) in router environment
4741 successfully. Tested with two routers, two servers and two
4744 * Tested channel message sending in router environment successfully.
4746 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Added silc_server_save_channel_key into server.[ch] to save the
4749 received channel key in Channel Key payload processing. It is
4750 also used in JOIN command reply handling.
4752 Equivalent function silc_client_save_channel_key added into
4753 client.[ch] into client library.
4755 * Changed JOIN command reply to send information whether the channel
4756 was created or not (is existing already) and the channel key
4757 payload. Changed protocol specs accordingly.
4759 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4760 the request was sent by ID and not by nickname. Crashed on
4763 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4766 now correctly save the received data.
4768 * silc_server_free_sock_user_data now notifies routers in the
4769 network about entities leaving the network.
4771 At the same time implemented functions silc_server_remove_id
4772 and silc_server_send_remove_id to receive and send REMOVE_ID
4773 packets. The packet is used to notify routers in the network
4774 about leaving entities. The ID removed will become invalid in
4777 * Added function silc_idlist_del_server into server. Removes and
4778 free's server entry from ID list.
4780 * silc_server_private_message function now checks, if we are router,
4781 that the destination ID really is valid ID, naturally.
4783 * In router when NEW_ID packet is received (for new client) the
4784 hash of the Client ID is saved in the ID Cache but the
4785 client->nickname is set to NULL, instead of putting the hash
4788 IDENTIFY command now also checks that client->nickname must be
4789 valid. If it is not if will request the data from the server who
4790 owns the client. Added new function
4791 silc_server_command_identify_check.
4793 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4794 to set the command to already allocated Command Payload.
4796 * Tested private message sending in router environment with two
4797 routers, two servers and two clients. Fixed minor bugs and now
4800 * Fixed segfault from client's NAMES command. Used to crash if
4803 * Forwarded packets must not be routed even if it is not destined
4804 to the receiver. Changed server code comply with this.
4806 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Added `require_reverse_mapping' boolean value to ServerParams
4809 structure. If TRUE (not default) the server will require that
4810 the connecting host has fully qualified domain name.
4812 If the reverse mapping is not required and hostname could not be
4813 found the IP address is used as hostname.
4815 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Implemented version string checking to both client and server.
4818 The check is incomplete currently due to the abnormal version
4819 strings used in development version of SILC.
4821 * Changed all command functions in server to use the new
4824 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Changed char *data to unsigned char *data in ID Cache system to
4827 support binary data as ID Cache data. Changed code to support
4828 binary data in lib/silccore/idcache.c.
4830 * Renamed silc_server_packet_relay_command_reply to
4831 silc_server_command_reply as it is normal packet receiving
4832 function. Rewrote the function to accept command replys for
4833 servers and not only for clients.
4835 * Mark remote router always as registered server if we are connecting
4836 to it. Otherwise, commands sent by the router to us are ignored.
4838 * All ID List find routines now returns the ID Cache Entry pointer
4839 as well if requested.
4841 * WHOIS command works now in router environment, tested with two
4842 routers, two servers and two clients.
4844 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4845 in router environment (as it is almost equivalent to WHOIS) but
4846 hasn't been tested thoroughly. Added new functions:
4848 silc_server_command_identify_parse
4849 silc_server_command_identify_send_reply
4850 silc_server_command_identify_from_client
4851 silc_server_command_identify_from_server
4853 * Disabled route cache adding because adding two different ID's with
4854 same IP replaces the old cache entry thus giving wrong route.
4855 The entry->router->connection is always the fastest route anyway
4856 so route cache may not be needed. Of course, new routes maybe
4857 established after receiving the ID when the entry->router->connection
4858 might not be anymore the most optimal.
4860 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Add route cache for received ID for fast routing.
4864 * Added silc_server_packet_route to route received packet on router
4865 that is not destined to us.
4867 * Renamed silc_server_get_route to silc_server_route_get.
4869 * Added id_string and id_string_len fields into SilcServer to
4870 include encoded ServerID for fast comparing without excess
4871 encoding of the ID's.
4873 * Cleaned up WHOIS command on server side. Added following static
4876 silc_server_command_whois_parse
4877 silc_server_command_whois_check
4878 silc_server_command_whois_send_reply
4879 silc_server_command_whois_from_client
4880 silc_server_command_whois_from_server
4882 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4883 arguments in command replies. All command functions should be
4884 updated to use this macro.
4886 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Minor typo fixes on command reply handling on server.
4890 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added silc_server_command_add_to_channel internal routine to add
4893 the client to the channel after router has created the channel and
4894 sent command reply to the server.
4896 * Added generic silc_server_send_command to send any command from
4899 * Use static buffer with ID rendering instead of duplicating data.
4901 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Fixed a channel user mode bug when joining to a channel server gave
4904 everybody channel founder rights, oops.
4906 * We mark ourselves as the router of the incoming server connection
4907 if we are router ourselves. This way we can check in some packet
4908 sending functions whether it is locally connected server. For
4909 incoming router connections we put NULL.
4911 * For router sending packets locally means now always sending the
4912 packet cell wide; to local clients and local servers. For normal
4913 server sending packet locally means sending it to only local
4916 * Fixed the JOIN command to really work in router environment. If the
4917 channel is created it is always created by the router. Router is
4918 also responsible of making the initial joining to the channel,
4919 sending JOIN notify to the sending server and distributing
4920 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4921 does not exist server doesn't do anything else but forward the
4922 command to the router which performs everything.
4924 * Added silc_server_send_channel_key function to send the Channel Key
4927 * Added silc_server_create_channel_key to create new channel key. The
4928 channel key is now re-generated everytime someone joins or leaves
4929 a channel, as protocol dictates. Note: channel->key_len is the
4932 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4935 packet_receive.[ch] to separate packet sending and receiving
4936 routines. The server.[ch] now includes everything else including
4937 actual packet processing (writing and reading data) and other
4940 Renamed silc_server_private_message_send_internal to
4941 silc_server_send_private_message. The routine is still though
4942 used only to relay private messages as server does not send
4943 private messages itself.
4945 Renamed silc_server_new_channel to silc_server_create_new_channel
4946 and added new function sicl_server_new_channel that handles the
4947 incoming New Channel packet. Added also new sending function
4948 silc_server_send_new_channel to send New Channel Payload.
4950 * Added new function silc_server_notify to process incoming notify
4951 packet to the server/router. Server may then relay the notify
4952 to clients if needed.
4954 * Added new function silc_server_new_channel_user to process incoming
4955 New Channel User packet. Router will redistribute the packet and
4956 send JOIN notify to its local clients and locally connected servers
4957 if needed. Normal server will send JOIN notify to its local client
4958 on same channel when received this packet. Added also corresponding
4959 sending function silc_server_send_new_channel_user to sent the
4962 * Added boolean route argument to send_notif_to_channel and
4963 packet_send_to_channel functions to attempt to route the packet
4964 if it is TRUE and send only locally if it is FALSE.
4966 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * silc_server_replace_id now broadcasts the received replace ID
4969 packet if it is not broadcast packet already. The router must
4970 broadcast to inform other routers about changed ID.
4972 * Added backpointer to server's router into SilcServer context in
4973 silcd/server_internal.h.
4975 * Fixed silc_server_packet_broadcast to send correct broadcast
4978 * The channel key is now distributed to the local client as soon
4979 as it is received from the router (in router environment) so that
4980 no other packet may be sent for the channel until client has
4983 * silc_server_remove_channel_user now broadcasts the received
4984 Remove Channel User packet if it is not broadcast packet already.
4985 The router must broadcast to inform other routers about removed
4988 * Added users field into SilcPacketContext that is a reference count
4989 of the context. One can increase the reference count by calling
4990 silc_packet_context_dup which is now changed to just increase the
4991 reference count instead of duplicating the data. The reference
4992 count is decresed by calling silc_packet_context_free that will
4993 free the data after the reference count hits zero.
4995 For now on the packet context and everything allocated into it
4996 (including the raw packet from network) must be freed by calling
4997 the new silc_packet_context_free function. Added also new function
4998 silc_packet_context_alloc that must be used now to allocate the
4999 context. This also means that if a routine is asynchronous from
5000 silc_[client/server]_packet_parse_type the packet context must
5001 be duplicated by calling silc_packet_context_dup. Otherwise it
5002 gets free'd after silc_[client/server]_packet_parse_type returns.
5003 Also, one must remember that if packet is duplicated then its
5004 reference count must be decresed by calling the free function as
5005 many times as it was duplicated.
5007 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5008 from both client and server.
5010 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Made joining to a channel working in router environment.
5014 * Cleaned up JOIN command on server side and create function
5015 silc_server_command_join_channel internal routine to make the
5018 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Changed silc_command_pending list to SilcDList. Also, added
5021 `ident' field to SilcServerCommandPending structure to identify
5022 the reply and to call correct callback.
5024 Added silc_server_command_pending_check function to replace the
5025 corresnponding macro. The silc_command_pending list is not
5028 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5029 to set identifier to previously allocated Command Payload. It
5030 is used to set identifier for command when resending Command
5033 * Added silc_command_payload_encode_payload to encode Command
5034 Payload buffer from SilcCommandPayload structure.
5036 * Added silc_argument_payload_encode_payload to encode Argument
5037 payload buffer from SilcArgumentPayload structure.
5039 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Changed WHOIS command to support router connection on server side.
5042 The whois request is always sent to router unless the server is
5043 standalone server. After server has received the reply from the
5044 router will it send the reply to the client.
5046 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5047 broadcast received broadcast packet. The function is used only
5048 by router. The broadcast packet is always sent to the router's
5051 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5052 render given ID to printable string, for log files for example.
5054 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Made basic router to router connections working. At least they
5057 can now connect to each other but nothing really works the way
5058 they are supposed - yet.
5060 * Added new initiator token to RouterConnection configuration
5061 file in silcd/serverconfig.[ch]. It is used to tell whether we
5062 are the initiator to the remote router or whether we'll expect
5063 the other end to connect.
5065 * Moved registering of listener task to silc_server_init, hence
5066 the server starts listenning as soon as it is run, even if it
5067 does not have connections to other routers. Let's see how well
5070 * Changed default connection retry timeouts for more suitable in
5073 * Removed cipher and such arguments from silc_idlist_add_client
5074 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5075 Added new function silc_idlist_add_data to add the keys and stuff
5078 * Added SilcIDListData structure and added it to SilcClientEntry
5079 and SilcServerEntry as their first field in the structure. This
5080 way we can explicitly cast the ID entries to the SilcIDListData
5081 structure and get common data for the entries. In past, we had
5082 to first check what type of connection it is and then cast it to
5083 correct ID entry type. Now, we can directly cast the opaque
5084 pointer to the SilcIDListData (no matter what ID entry it actually
5085 is) and get the data needed.
5087 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5090 in some circumstances even if threre were timeout tasks, though not
5091 IO tasks, but tasks anyway. Now fixed.
5093 * Defined SilcServerConnection structure to hold connection specific
5094 stuff about directly connected servers and routers. The definition
5095 is currently in silcd/server_internal.h. I thought about having
5096 a bit more important role fro this struct but for now it is used
5097 only when connecting to other server (or router actually).
5099 * Added connecting retry support in server when connecting to
5100 router(s). The retry feature implement exponential backoff
5101 algorithm. Also, added SilcServerParams structure to hold default
5102 parameters for server. For now, it include these retry settings
5103 and are hard coded. After server is moded to be as Silc Server
5104 Library this structure will be more important.
5106 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Changed client librarys channel->clients table to SilcList and
5109 changed code accordingly.
5111 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Changed client's channel table to SilcList and changed code
5114 accordingly. Also changed SilcChannelClientEntry to include back-
5115 pointer to the channel so that client entry can use that structure
5116 as list as well and we have fast cross-reference to the channel.
5117 This change dramatically decreased the complexity of channel
5118 handling with client entry and vice versa (removed one extra
5119 loop when searching for channel entry from many functions).
5121 * Changed server->sim from table to SilcDList and changed code
5124 * NAMES command can now be used from user interface. It will show
5125 the user list on the channel, neatly.
5127 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5128 Code now saves realname of the user if it becomes available.
5130 * Renamed configure.in to configure.in.pre and made ./prepare
5131 script to automatically add correct version string to
5132 configure.in which it creates from configure.in.pre.
5134 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * NAMES command reply now shows users mode with the nickname when
5139 * Moved silc_client_ch[u]mode[_char] functions from
5140 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5141 place sucks, they are utility functions and should be in some
5144 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5146 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5149 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Added TRQ (efficient deque and list library) into lib/trq. This is
5154 a very good list library that is currently used in the SILC. Defined
5155 SilcList API over the library because I didn't like the API very
5156 much. See lib/trq/silclist.h for the API and examples of how to
5157 use the API. Fixed various places in the code to use the new
5158 SilcList API. The SilcList is meant for lists that has a structure
5159 already defined as a list. It is not suitable to add just some
5160 context to the list (in TRQ, the context is the list actually).
5162 So, I defined SilcDList that can be used for the purpose where
5163 predefined list structure does not exit. This can be used as
5164 such list. Now some context just can be added to the SilcDList.
5165 Currently this list is not used in the SILC just yet, though there
5166 are a lot places where this can replace dynamically allocated
5167 tables and I will fix these places, later, to use SilcDList.
5168 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5169 and use TRQ internally).
5171 Also fixed some annoying warning messages that the original TRQ
5172 code generated. Also minor changes to TRQ's Makefile.in.
5174 * Added support for querying by Client ID to both WHOIS and
5175 IDENTIFY commands into server, as required by the protocol.
5177 * Removed method function pointers from SilcBuffer structure. They
5178 weren't used to anything and just increased the context size for
5179 no good reason. This change also made silc_buffer_alloc and
5180 silc_buffer_free functions inline functions.
5182 * Disabled command flooding detection support until it's fixed so
5183 that it accepts commands in but does not execute them more than once
5186 * Added silc_net_localhost(), to return local hostname, into
5187 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5188 that must be initialized before calling silc_client_init.
5190 * Added new function: silc_server_send_notify_on_channels to send
5191 notify messages to all channels client has joined. It is assured
5192 that the message is sent only once per client.
5194 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5195 lib/silcutil/silcutil.[ch] as silc_format function. The new
5196 function is generic and is used by server as well, not only by
5197 the logging routines.
5199 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5200 the provided version string was not acceptable. Added new function:
5201 silc_ske_check_version into lib/silcske/silcske.h. The function
5202 must be implemented by the application (client or server) and it
5203 does not reside in the SKE library. The function checks the version
5204 string remote end sent.
5206 * Added back pointers (to opaque context and to SilcSocketConnection)
5207 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5209 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5210 duplicate packet context structure.
5212 * Changed `notify' client operation to send same arguments as client
5213 receives from server except for ID's. ID's are mapped to correct
5214 ID entry and that is returned. Also, if channel entry is not sent
5215 by server but the notify is for channel the channel entry is sent
5216 to application (otherwise application doesn't know that it is for
5217 channel (library gets it from packet's Destination ID)).
5219 * Added silc_client_remove_from_channels into client library to
5220 remove a client from all channels it has joined to. Used when
5221 received SIGNOFF notify from server. Added also new function
5222 silc_client_replace_from_channels to replace old ID entry with
5223 new ID entry on all channels. Used when received NICK_CHANGE
5226 * Fixed ID Cache list handling in silc_idlist_get_client in
5227 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5228 to get (or query) client by ID.
5230 * Updated TODO list.
5232 * Added connection authentication status message defined by the
5233 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5234 support for these into the code in client and server side.
5236 * Added generic function silc_client_send_command to send any command
5237 with variable argument list. Application should use this function
5238 to send commands if the command functions provided by the library
5239 does not suite for the application's user interface needs.
5241 * Added new `failure' client operation. Application is notified about
5242 received failure packet if client is executing a protocol. In this
5243 case the protocol's execution has failed.
5245 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5246 is required by the protocol.
5248 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5249 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5252 * Added status flag to SilcSKE object to indicate realtime status
5253 of the SKE protocol.
5255 * Application receives now exactly same command reply arguments as
5256 the library receives from server. However, if ID is received the
5257 corresponding ID entry is returned to the application (eg. Client
5258 ID is mapped to correct SilcClientEntry entry and that is returned).
5259 Changed command_reply client operation due to this change.
5261 * Changed all ID's in commands and in command replys as ID Payloads.
5262 Change affected both client and server side codes.
5264 All ID's sent in SILC network (with execption of ID's in SILC
5265 Packet header) are sent in ID Payload to support variable length
5268 * Server now notifies nick changes and notifies all clients on
5269 the channels about the new nickname (about the new Client ID,
5272 * Implemented CMODE command to change channel modes. Supports all
5273 channel modes defined by the protocol specs except ban and invite
5274 lists. (Also, private channel key mode is supported but support for
5275 setting private channel key in client is missing, thus, this mode
5276 has no effect on client side (except that server requires that the
5277 client uses private channel key and normal channel traffic does not
5280 Also, invite mode works per se, but INVITE command does not work
5281 yet correctly, so you can set channel as invite only channel but
5282 inviting clients to the channel does not work (it is yet to be
5283 thought what's the best way to do it).
5285 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5286 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5287 Implemented CUMODE command to change user's mode on the channel.
5288 Supports all modes defined by the protocol specs.
5290 * Added NAMES command reply to return users modes on the channel.
5292 * Removed unnecessary and slow ciphers from lib/silccrypt.
5294 * Set SO_KEEPALIVE option to connection sockets by default.
5296 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5298 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5299 redefined the Notify Payload into protocol specs.
5301 * Added silc_id_payload_parse_id to get ID directly from raw
5304 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5307 accept searching by Client ID as well.
5309 * Added support for LEAVE and SIGNOFF notify types in client library.
5311 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5312 to parse ID Payload from raw data.
5314 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added flags parameter into silc_ske_assemble_security_properties
5317 function in lib/silcske/silcske.[ch].
5319 * Changed notify client operation to fit better for notify messages
5320 sent by server. The notify payload received from server is now
5321 passed to the application (after parsing it to SilcNotifyPayload).
5322 It is application's responsibility to retrieve the arguments
5323 from the payload and show the message the way it wants. The message
5324 sent by server is implementation specific.
5326 * Changed public keys to comply with the protocol specification.
5327 Old public keys are not supported anymore and are not compatible.
5329 * Removed nickname from Channel Payload as the latest draft removed
5330 it. The client must resolve the nickname from the NAMES command
5331 reply received when it joined the channel.
5333 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5335 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Fixed some errors in protocol specification drafts.
5339 * Created lib/silccore/silcnotify.c to implement Notify Payload
5340 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5341 generic payloads described by protocol specifications. The file
5342 includes implementations for ID Payload and Argument Payload.
5344 * Changed Command Payload implementation to use the new Argument
5345 Payload. Changed command_xxxx_payload to command_payload_xxxx
5346 to comply with SILC coding conventions.
5348 * Added suppport for Argument Payload handling in Notify Payload
5349 implementation as protocol requires it. Added the new support
5350 into server and client lib as well.
5352 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Added support for multiple nicknames on same channel. [n] is
5355 added locally to the nickname if there are more than one same
5356 nicknames on the channel.
5358 * Server now sends all nicknames that matched WHOIS request.
5359 Client also shows the list received from server.
5361 * Added TOPIC command to client side. User can now set and show
5362 current topic on channel.
5364 * Added MOTD command to client and server. Also, server sends the
5365 motd when client connects to the server.
5367 * Changed version strings to comply ISO 8601.
5369 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Fixed protocol error handling in client library. It should now
5372 cope even if the SKE fails for some reason.
5374 * Made new protocol specification drafts for submitting to IETF.
5376 * Implemented TOPIC command to server in silcd/command.c.
5378 * Added two new notify types into lib/silccore/silcnotify.h:
5379 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5380 notify nickname change and topic setting/change on a channel.
5382 * API change of command_reply operation in client library. The
5383 application gets now the status type received from server as well.
5385 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5389 * Cras fixed and optimized the packet handling even further and
5390 it should work now. Minor change to the prototype of function
5391 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5393 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Added new function into lib/silcutil/silcschedule.[ch]:
5396 silc_schedule_with_fd to select() a specified fd. The function
5397 returns after timeout expires or data arrives or goes. The
5398 function is used by packet routines to wait that all data is
5399 received from network.
5401 * Fixed data reading from network in lib/silccore/silcpacket.c.
5402 The code now assures that all data is read from the fd and then
5403 continues packet processing. This was a bug fix since the code
5404 used to drop some data in some circumstances.
5406 * Added new function into lib/silcclient/client.[ch]:
5407 silc_client_start_key_exchange to start key exchange after
5408 connection has been established to server. The code internally
5409 now uses this funtion but its main purpose was to provide it
5410 for applications that perform their own connecting. After
5411 application has created a connection it merely calls this
5412 function to start the key exchange between client and server.
5413 The library takes care of everything else after that.
5415 Updated also lib/silcclient/README to explain the usage of
5418 * Do not send to application information that connection has
5419 been established. Application gets notified it by connect
5422 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Applied cras's patch to add silc_schedule_one function. The
5425 function runs scheduler once and returns.
5427 * Fixed the scheduler after cras messed it up. The timeout
5428 handling works now as it's supposed to work.
5430 * Added into lib/silccore/ silcnotify.h to include notify
5431 message types support. Changed silc_server_send_notify*
5432 functions, in server.[ch], to support those new notify types.
5433 Added the support for the notify types into client library,
5434 as well. Added new notify client operation into ops.h in
5437 * Changed silc_server_packet_send_to_channel to send normal
5438 packets instead of just channel message packets. The function
5439 is now used to send the notify packets to channels. It is not
5440 used to send channel message packets anymore, as server never
5443 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5444 va_arg()s as it seems to require it nowadays. I guess, if SILC
5445 is compiled with older va_arg() the new code should work anyway.
5447 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Splitted core library. Core library (lib/silccore) includes
5450 now only SILC protocol specific core (and common) components.
5451 Created new utility library (lib/silcutil) that includes more
5452 generic purpose stuff. The stuff for util library was taken
5453 from the old core library. This was minor and easy split.
5455 * Created SILC Client Library (lib/silcclient) that includes
5456 implementation of the SILC client without user interface. This
5457 was major move from silc/ directory. The code has been changed
5458 so that it is transparent towards the user interface. The
5459 silc/ directory includes now the same user interface as before
5460 and it uses the new client library. Read lib/silcclient/README.
5461 Basicly, the client library performs everything else related
5462 to SILC except user interface handling. Also, configuration
5463 files are considered to be part of user interface and library
5464 does not handle them.
5466 This change also changed a lot of structures, function naming etc.
5467 Most important change was that SilcClientWindow object was
5468 renamed to SilcClientConnection in the client library. Created
5469 also new file lib/silcclient/ops.h. Also added new files
5470 silc/local_command.[ch] and silc/client_ops.[ch].
5472 All these changes were made to make it easier for user interface
5473 designers to create what ever user interface for the SILC client
5476 It is also expected that the server will be moved to lib
5477 directory as well and SILC Server Library will be created;
5478 sometimes in the future.
5480 * Removed Local commands from lib/silccore/silccommand.h as
5481 they are application specific and new client library does not
5482 handle any of those anymore.
5484 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5485 old client implementation in silc/.
5487 * Added support for callback functions in SILC_LOG_* macros.
5488 Application can now set its own callbacks that will be called
5489 instead of using the default functions that will always print
5490 the debug messages to stderr (or stdout). Also, debugging can
5491 now be disabled by setting silc_debug to FALSE and re-enabled by
5492 setting it to TRUE. Note, that logging will still work even
5493 if debugging is disabled.
5495 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5496 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5497 silc_log_reset_debug_callbacks.
5499 * To enable debugging in silc client one must give now -d
5500 option on command line.
5502 * Changed silc_schedule_init to automatically allocate task queues
5503 if they are not allocated before calling it.
5505 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Added GMP 3.1 into math library.
5509 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5512 a channel in SILC network. The packet is used by servers and
5513 routers to notify other routers that user has left a channel.
5514 This little feature was missing until now. Added the feature
5515 to protocol specification as well.
5517 Added functions: silc_server_send_remove_channel_user and
5518 silc_server_remove_channel_user into server.[ch].
5520 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5521 lib/silccore/silcpacket.h. However, they are not implemented
5524 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Fixed joining to a channel and sending channel messages
5527 between server and router. The channel message sending should
5528 now work inside a cell.
5530 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Fixed the private message sending between server and router.
5533 The private message sending should now work inside a cell.
5535 * Added silc_server_replace_id into server.[ch] to replace
5536 existing ID in the SILC network.
5538 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5539 and silc_idlist_replace_server_id into idlist.[ch] in server.
5541 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Fixed the server to server connections. Server can again now
5544 connect to router. Router to router connections probably does
5547 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added dynamic protocol registering support. Now protocols can
5550 registered and unregistered on the fly. Patch by cras.
5552 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Added lib/contrib directory to hold routines that some platforms
5555 don't have but are needed by SILC.
5557 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5558 into lin/contrib to provide getopt() and getopt_long() for
5559 those who don't have it.
5561 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Added AWAY command to client. When away message is set and
5564 client receives a private message packet the client automatically
5565 replies to the sender with the away message.
5567 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5568 bug seemed to be the cause of recent problems when compiling
5571 * Added version detection support to SKE protocol specification
5572 and added the new changes to the SKE implementation as well.
5573 There were other minor changes in the SKE protocol as well.
5575 Many changes in lib/silcske/silcske.[ch] and in
5576 lib/silcske/payload.[ch].
5578 * Added ^U functionality, clear input line. Patch from cras.
5580 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Mainly small bugfixes on core library. Fixed some debugging
5583 logging and buffer overflow in silclog.c.
5585 * Updated config.sub and config.guess on the distribution tree.
5587 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Added command lagging support in server. Client may execute
5590 commands now only once in two seconds.
5592 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Optimized packet reception. MAC computation and checking is now
5595 also more optimized. A lot previously duplicated code is now
5596 used as generic by both client and server.
5598 * Fixed key pair generation in clientutil.c
5600 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added into lib/silccore/silcbufutil.[ch] new function;
5603 silc_buffer_realloc.
5605 * Moved generic packet sending/encryption functions to
5606 lib/silccore/silcpacket.[ch] from client and server. Some
5607 rewriting of the functions.
5609 * Moved all generic packet reception/decryption functions to
5610 lib/silccore/silcpacket.[ch] from client and server. The
5611 packet processing is now much cleaner in both client and server.
5612 These were major changes in both client and server.
5614 * Created many common functions in server to do packet sending.
5615 Previously code were duplicated a lot, this has been removed
5618 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Rewrote major parts of the ID cache system. Don't know
5621 whether it is better now or not but at least the API is more
5624 * Major rewrite on ID cache stuff on client because of the ID
5625 cache API changes. Added idlist.c to client.
5627 * Also major rewrite on ID cache stuff on server as well.
5628 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5629 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5630 in hand, instead they are all put into the ID cache system now.
5631 All server_idlist_* routines uses ID cache now instead of
5632 traversing its own lists (those lists does not exist anymore).
5633 SilcIDList though still exists. Also, SilcXXXEntry's are
5636 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Finally made the SKE implementation compliant to the protocol
5639 specification. All mp integers are now binary encoded as
5640 opposed being HEX encoded.
5642 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5645 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5646 functions: silc_[encode/decode]_pem. Also added function
5647 silc_encode_pem_file to PEM encode with newlines ('\n') for
5650 * SILC public keys are now encoded either PEM or binary. Same
5651 option is for private keys as well. By default private keys
5652 are binary encoded and public keys PEM encoded. Silly HEX
5653 encoding were removed.
5655 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5656 function to create fingerprints.
5658 * Fixed a bug in SHA1; does not change the original data anymore.
5660 * Partly implemented INFO command on client and server side.
5661 Fixed CLEAR command. Changes to SERVER command; show current
5662 server(s) when giving command without arguments. Added
5663 VERSION command to client.
5665 * Added check to server that unregistered connections cannot
5666 execute commands (unless it is specificly allowed).
5668 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Fixed screen refresh.
5672 * Fixed channel joining bug from client. On some circumstances
5673 client tried to join to a channel it had already joined.
5675 * Added public key verification process into client's protocol.c.
5676 The client now verifies the public key from user and saves
5677 it into ~./silc/serverkeys/ directory.
5679 Added into: clientutil.[ch]: silc_client_verify_server_key.
5681 * Changed SKE protocol's silc_ske_initiator_finish function
5682 to accept callback function that verifies the received public
5683 key. Removed old silc_ske_verify_public_key function.
5685 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5688 silc_pkcs_private_key[_data]_set.
5690 * Made the password and public authentication more cleaner in
5691 server's protocol.c.
5693 * Removed historic and obsolete protocol `channel_auth' from
5694 both client and server.
5696 * Removed wrong way of sending command status messages from
5697 server to client in server's command.c. The old way violated
5698 protocol specification.
5700 Changes to silccore/silccommand.[ch]: removed
5701 silc_command_encode_status_payload -> not needed anymore,
5702 changed silc_command_encode_payload_va to accept extra
5703 argument on variable argument list. The argument type must
5704 now be provided to the function. Also, added new function:
5705 silc_command_encode_reply_payload_va which is same as
5706 normal command_encode_payload_va except command status type
5707 is provided as extra argument.
5709 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Added ~./silc directory handling. The directory includes the
5712 public and private keys for the client.
5714 Added silc_client_check_silc_dir, silc_client_create_identifier
5715 and silc_client_load_keys.
5717 * Implemented SILC protocol compliant public key. Added public
5718 and private key saving to and loading from files.
5720 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5721 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5722 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5723 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5724 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5726 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5727 silc_pkcs_load_[public/private]_key.
5729 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added silc_server_get_route (route.[ch]) to get connection
5732 data for the fastest route for given ID.
5734 * Implemented INVITE command on client and server. The command
5735 were re-defined in the SILC Protocol Specification and the
5736 implementation now complies with the specification.
5738 * Implemented PING command on client and server.
5740 * Implemented NAMES command on client and server. The server side
5741 supports currently only normal server not router server yet.
5742 Some changes to NAMES definition in SILC protocol specification.
5744 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Implemented LEAVE command on client and server.
5748 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5749 again. This change was made to the protocol as well. Server
5750 should not violate the protocol specification anymore.
5752 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5755 was tested. SOCKS4 was not but should work anyway.
