11 * Added silc_net_localip to return local host's IP address.
12 Affected file lib/silcutil/silcnet.[ch].
14 * If key exchange or rekey protocol is active for a connection
15 parse all packets syncronously since there might be packets
16 in packet queue that we are not able to process without first
17 processing packets before them. Affected file silcd/server,
18 lib/silcclient/client.c.
20 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
21 whether library should continue processing the packet.

55 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Resolve the client info when received private message or
58 channel message for a client which nickname we don't know.
59 Affected files lib/silcclient/client_prvmsg.c and
60 lib/silcclient/client_channel.c.
62 * Do not crash in /KEY if client is not connected. Affected
63 file irssi/src/silc/core/silc-channels.c.
65 * Added SilcClientStatus field to the SilcClientEntry in the
66 lib/silcclient/idlist.h.
68 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
69 is incomplete and is being resolved, it won't be resolved
72 Make sure also that USERS command reply does not resolve
73 twice information. Affected file is
74 lib/silcclient/command_reply.c.
76 Make sure that silc_client_get_clients_by_list does not
77 resolve twice same information.
79 * Check for valid client->id in the silc_server_free_client_data.
80 Affected file silcd/server.c.
82 * Fixed /GETKEY nick@server not to crash if the server entry

105 * Redefined the SILC packet header to include the padding
106 length. Affected file lib/silccore/silcpacket.[ch].
108 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
109 length for maximum padding up to 128 bytes). Affected
110 file lib/silccore/silcpacket.h.
112 * Removed all backwards support for old 0.5.x MAC thingies.
113 The SILC packet header change makes it impossible to be
114 backwards compatible.
116 * Send the ENDING packet with timeout in the backup resuming
117 protocol. This is to assure that all routers has connected
118 to the primary router. Affected file silcd/server_backup.c.
120 * Changed the RNG to take the first IV from random data. It
121 used to take it from zero actually. Changed the RNG also
122 to use /dev/urandom during session. /dev/random is used
123 in initialization. Affected file lib/silccrypt/silcrng.[ch].
125 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
127 * Changed the SILC packet header to have the first two bytes
128 (the packet length) encrypted. Affected files aroung the
129 code tree, lib/silccore/silcpacket.[ch]. Removed the
130 SilcPacketCheckDecrypt callback. It is not needed anymore
131 since the silc_packet_receive_process will determine now
132 whether the packet is normal or special.
134 * Implemented the unidirectional MAC keys. Affected files
135 lib/silcske/silcske.c, silcd/protocol.c and
136 lib/silcclient/protocol.c.
138 * Implemented the packet sequence number to the MAC computation.
139 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
140 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
141 lib/silcclient/protocol.c.
143 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
145 * Allow backup router to announce servers. All servers
146 announced by backup router are added to the global list
147 automatically. Update hte server's socket to our primary
148 router also when backup router announces a server.
149 Affected file silcd/packet_receive.c.
151 * Do not update the client->router in the function
152 silc_server_udpate_clients_by_server if the client is on
153 global list. We might fail to find any specific server
154 for locally connected clients and local cell clients. They
155 should still use the `from' and not `to' as client->router.
156 This fixes backup router resuming protocol. Affected file
159 * Decrease channel statistics count only if the channel
160 deletion worked. Affected files are silcd/server.c and
163 * Added silc_server_update_servers_by_server to update origin
164 of all server entries. Used during backup router protocol.
165 Affected files silcd/server_util.[ch], silcd/server.c. and
166 silcd/backup_router.c.
168 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
169 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
170 silc_hmac_get_hash and silc_hmac_get_name. Affected file
171 lib/silccrypt/silchmac.c.
173 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
175 * Assure that router cannot reroute the same channel message
176 to the sender. Affected file silcd/packet_receive.c.
178 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
180 * Made better checks that the channel message is not sent
181 to the router it came from. Affected file is
182 silcd/packet_send.c. Fixed memory leak too.
184 * Announce informations for incoming router connection, but
185 only after checking if it is replaced by backup router.
186 Affected file silcd/packet_receive.c.
188 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Fixed the backup resuming protocol to work in multiple
191 router environment. Affected file silcd/server_backup.c.
193 * Route packet only to one router in the function
194 silc_server_packet_send_to_channel. Affected file is
197 * Fixed silc_server_send_notify_dest to set the broadcast
198 flag. Fixed the silc_server_send_notify_topic to actually
199 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
200 Affected file silcd/packet_send.c.
202 * Changed the SFTP Filesystem interface. Changed the
203 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
204 the filesystem operation function. The SilcSFTPFilesystem
205 is now a context that is allocated by all filesystem allocation
206 functions and it already includes the operations structure
207 and filesystem specific context. It is given as argument
208 now to the silc_sftp_server_start. This made the interface
209 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
210 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
212 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
214 * Changed the backup router adding and getting interfaces
215 in the server. The router that will be replaced by the
216 specified backup router is now sent as argument. Affected
217 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
220 * Added silc_net_addr2bin_ne to return the binary form of
221 the IP address in network byte order. Affected files
222 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
224 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

238 protocol specification.
240 * Removed one redundant channel key generation from normal
241 server during joining procedure. Removed one redundant
242 channel key sending from server to router during joining
243 procedure. Affected file silcd/command.c.
245 * Made minor bugfixes to the backup router resuming protocol.
246 Affected file silcd/server_backup.c, server.c.
248 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

266 send any data. Affected file silcd/packet_send.c.
268 * Assure that if outgoing data buffer is pending do not force
269 send any data. Affected file lib/silcclient/client.c.
271 * Implemented the backup router support when the primary router
272 goes down. The servers and routers can now use the backup
273 router as new primary router without loosing connectivity.
275 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
278 in the server to indicate disabled entry. All data read
279 from the connection will be ignored and no data is sent
280 for entry that is disabled. Affected files are
281 silcd/idlist.h, silcd/server.c.
283 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
285 * Created SFTP client and server test programs in the
286 lib/silcsftp/tests directory.
288 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
290 * Implemented memory filesystem (virtual filesystem) for
291 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
294 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
296 * Implemented the SFTP (SSH File Transfer Protocol) to the
297 lib/silcsftp. It includes SFTP client and SFTP server
300 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
302 * Moved lib/silccore/silcprotocol.[ch] to the
303 lib/silcutil library.
305 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
306 take variable argument list pointer as argument. Affected
307 file lib/silcutil/silcbuffmt.[ch].
309 * Added silc_buffer_set function that is used to set data
310 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
311 Affected file lib/silcutil/silcbuffer.h.
313 * Changed various routines in the core library to use the new
314 silc_buffer_set instead of allocating new buffer only for
317 * Added 64-bit value formatting and unformatting support to the
318 silc_buffer_[un]format routines. Affected file is
319 lib/silcutil/silcbuffmt.[ch].
321 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
322 to includes/bitmove.h.
324 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
326 * Fixed channel user mode saving in client library. Affected
327 file lib/silcclient/command[_reply].c.
329 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
331 * Defined the file transfer to the SILC Protocol. Added
332 new packet type SILC_PACKET_FTP and defined File Transfer
333 Payload. The mandatory file transfer protocol is SFTP
334 (SSH File Transfer Protocol). Affected file in addition
335 of the internet draft is lib/silccore/silcpacket.h.
337 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
338 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
339 is used as part of backup router protocol when the primary
340 router of the cell is back online and wishes to resume
341 the position as primary router.
343 * Redefined the MAC generation keys in the protocol. The
344 same key is not used anymore in both direction. Both
345 direction will now use different keys for sending and
346 receiving. This fixes a potential security flaw. This
347 change causes incompatibilities in the protocol.
349 * Redefined also the MAC computation from the packet.
350 An packet sequence number is now added to the MAC
351 computation. This prevents possible replay attacks against
352 the protocol. This change too causes incompatibilities
355 Added `sequence' field to the SilcPacketContext to hold
356 the current sequence number for the packet.
358 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Added `created' field to the SilcIDListData in the file
361 silcd/idlist.h to indicate the time when the entry was
364 * Added `created' field to the SilcChannelEntry too. Affected
367 * Added `creation_time' aguments to all the announcement functions
368 in the server. If it is provided then only the entries that
369 was created after the provided time frame are actually
370 announced. Affected file silcd/server.[ch].
372 * The protocol says that the Channel ID's IP address must be
373 based on the router's IP address. Added check for this in
374 the silc_server_new_channel when processing incoming New Channel
375 Payload. Affected file silcd/packet_receive.c.
377 * Print out the correct version with --version in SILC client.
378 Affected file irssi/src/silc/core/silc-core.c.
380 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
382 * Fixed WHOWAS command to check for completnes of the client
383 entry always, not just when the command is coming from client.
384 Affected file silcd/command.c.
386 * Added new function silc_server_packet_queue_purge to purge the
387 outgoing data queue to the network. After the function returns
388 it is guaranteed that the outgoing packet queue is empty.
389 Affected file silcd/packet_send.[ch].
391 * Purge the outgoing packet queue in the rekey protocol's final
392 callback to assure that all rekey packets go to the network
393 before quitting the protocol. Affected file silcd/server.c.
395 * Added silc_client_packet_queue_parse as similar function as
396 in server to the client library. The affected file is
397 lib/silcclient/client.c.
399 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
401 * Splitted silcd/server.c and created silcd/server_util.[ch]
402 for utility functions.
404 * Added new socket flag SILC_SF_DISABLED to indicate that the
405 connection is open but nothing can be sent to or received from
406 the connection. Affected file lib/silcutil/silsockconn.[ch].
407 The checking for disabled socket is checked in the low level
408 silc_socket_write and silc_socket_read functions.
410 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
412 * Allow only nicknames and channel names that fits into the
413 7-bit unsigned char ASCII set. Affected file silcd/command.c.
415 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
417 * When processing JOIN command reply in server check that if
418 the channel exists in our global list we'll move it the local
419 list. Affected file silcd/command_reply.c.
421 * Fixed the check whether client is joined on the channel already
422 in JOIN command. Affected file lib/silcclient/command.c.
424 * Fixed the JOIN command reply to check whether the channel
425 already exists. Affected file lib/silcclient/command_reply.c.
427 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Added silc_ske_status_string to map the SKE error numbers
430 to readable strings. The affected files are
431 lib/silcske/silcske[_status].[ch].
433 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
435 * Do not show the private channels on the WHOIS channel list
436 as it is not allowed by the protocol. The affected file is
439 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
441 * Assure that the packet length digged from the actual packet
442 is something sensible in the silc_packet_decrypt_rest_special
443 in lib/silccrypt/silcpacket.c.
445 * Free and NULL the allocated pointer in silc_hmac_alloc if
446 the HMAC allocation fails. The affected file is
447 lib/silccrypt/silchmac.c.
449 * Print the selected security properties to the log files in
450 the server. Affected file silcd/protocol.c.
452 * Add SKE's reference counter even if calling the completion
453 callback manually. Otherwise it goes negative, although it
454 does not cause any problems. The affected file is
455 lib/silcske/silcske.c.
457 * Remove the client entry with short timeout after giving the
458 KILL command. Affected file lib/silcclient/command.c.
460 * Fixed to send error reply in WHOIS and IDENTIFY commands in
461 case all found clients are already disconnected (WHOWAS would
462 found them) in the server. Affected file silcd/command.c.
464 * Update the last_receive (time of last data received) to be
465 updated only when received private or channel message so that
466 the idle time showed in WHOIS makes more sense.
468 * Added boolean field `valid' in to the SilcClientEntry in the
469 client library to indicate whether the entry is valid or not.
470 This fixes the nickname change bug on channel when changing
471 the nickname to be same than the old (like nick to Nick) the
472 nickname formatter doesn't set the new nick anymore to Nick@host.
473 Affected file lib/silcclient/idlist.[ch].
475 * Now actually fixed the nickname changing on disconnection.
476 Added new function silc_change_nick to the Irssi SILC Client.
477 Affected file irssi/src/silc/core/client_ops.c,
478 irssi/src/silc/core/silc-nicklist.[ch].
480 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Check that the public key exists in the GETKEY command before
483 trying to encode it. Affected file silcd/command.c.
485 * Print some notifications on received public keys with GETKEY
486 command in the Irssi SILC Client. Affected files are
487 irssi/src/fe-common/silc/module-formats.[ch],
488 irssi/src/silc/core/client_ops.c.
490 * Use IDENTIFY command to resolve the server information in the
491 GETKEY command instead of INFO command. Affected file
492 lib/silcclient/command.c.
494 * All command reply functions in the client library now calls
495 the pending command reply callbacks even if an error has
496 occurred. The server has done this a long time and now it was
497 time to move the client library to this as well. Now all
498 errors can be delivered back to the pending command reply
499 callbacks if necessary. Affected files are
500 lib/silcclient/command[_reply].[ch].
502 * Change the nickname on disconnection back to the username
503 because in reconnect the server will enforce it to it anyway.
504 Affected file irssi/src/silc/core/silc-servers.c.
506 * Fixed a config file parsing bug in the Irssi SILC client.
507 Affected file irssi/src/silc/core/clientconfig.c.
509 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * When printing the channel mode on JOIN, verify that the
512 channel key and channel's HMAC are valid. Affected file
513 irssi/src/silc/core/client_ops.c.
515 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
518 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
519 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
521 * Removed channel key rekey task deleting from the function
522 silc_server_save_channel_key. Affected file silcd/server.c.
523 Added explicit timeout task context instead that is used to
524 delete the task if we are registering a new task before the
525 new task has elapsed.
527 * When channel key rekey occurs the client library now saves
528 the old channel key for a short period of time (10 seconds) and
529 is able to use it in case some is still sending channel
530 messages encrypted with the old key after the rekey. Affected
531 file lib/silcclient/[idlist.h|client_channel.c].
533 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
535 * Added check to the silc_server_new_id_real to not accept
536 new ID if it is the sender's own ID. Affected file is
537 silcd/packet_receive.c.
539 * Assure that we do not announce ourself or the one we've
540 sending our announcements when we're router and are announcing
541 servers to our primary router. Affected file silcd/server.c.
543 * Fixed silc_server_command_identify_check_client to assemble
544 correct WHOIS packet. It send corrupted WHOIS packet and
545 caused problem with router to router connections. Affected
546 file silcd/command.c.
548 Fixed also silc_server_command_whois_check the same way
549 as for the IDENTIFY command.
551 * Added new SilcIDListStatus to the server in the SilcIDListData
552 structure. The status now includes the current status of
553 the entry (like registered, resolved etc.). Affected file
554 silcd/idlist.[ch]. Defined a bunch of different status types
555 as well. This replaced the old boolean registered field as well.
557 Added resolve_cmd_ident field to the SilcClientEntry structure
558 too so that if the entry is for example being resolved so
559 another command may attach to the same pending command reply
560 without requiring to resolve the same entry again. This concept
561 should optimize the WHOIS and the IDENTIFY resolving under
562 heavy load by taking away unnecessary resolving for entries
563 that are being resolved already.
565 Added support for adding multiple pending commands for one
566 command idenfier. Affected file silcd/command[_reply].[ch].
568 * Fixed WHOIS and IDENTIFY save to remove the cache entry
569 before deleting the data. Otherwise the hash table will have
570 freed data in comparison functions. Affected file is
571 silcd/command_reply.c.
573 * Fixed silc_idlist_replace_client_id to add the new entry to
574 the cache with NULL nickname. Otherwise there will be invalid
575 memory as the nickname after the nickname is freed. Affected
576 file silcd/packet_receive.c.
578 * Fixed the silc_idlist_get_clients_by_hash. The entries was
579 saved into wrong slots because the previous number of entries
580 was not taken into account. Affected file silcd/idlist.c.
581 Fixed same thing in silc_idlist_get_clients_by_nickname too.
583 * If we are router and we receive JOIN notify to a channel that
584 does not have any users then notified client is marked as the
585 channel founder, as it is it. The affected file is
586 silcd/packet_receive.c
588 * Added to the extended hash table API's table_del_*ext functions
589 the destructor as argument too, so that the caller can decide
590 which destructor to use or whether to use destructor at all.
591 Affected file lib/silcutil/silchashtable.[ch].
593 * Fixed ID Cache purging. It actually deleted the entries from
594 the hash table after the data was freed. The hash table ended
595 up comparing freed memory. The affected file is
596 lib/silccore/silcidcache.c.
598 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
600 * Fixed Irssi SILC client's KILL command's HELP syntax.
602 * The USERS command now resolves the detailed user information
603 if the userinfo field is missing. Affected file is
604 lib/silcclient/command_reply.c.
606 * Do not print error in silc_file_read if the read file does
607 not exist. Just silently return NULL. Affected file is
608 lib/silcutil/silcutil.c.
610 * Fixed the silc_log_output to not wine about NULL filename
611 and to not create some bogus " " filename. Affected file is
612 lib/silcutil/silclog.c.
614 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Fixed various printing bugs on the user interface in the
617 Irssi SILC Client. Minor changes that were forgotten from
620 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
622 * Fixed the configure.in.pre and the compilation and distribution
623 environment to support the new autoconf 2.52. That version is
624 now required to compile the CVS trunk.
626 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
628 * Renamed function silc_parse_nickname to silc_parse_userfqdn
629 to generally parse user@fqdn format strings. Affected file
630 lib/silcutil/silcutil.c.
632 * Added nickname_format and nickname_force_format fields to the
633 SilcClientParams structure. The first one defines the format
634 for the nicknames that the library will enforce if the receives
635 multiple same nicknames. The second one is boolean value and
636 can be used to force the library to always enforce the format
637 to the nicknames regardles whether there are multiple nicknames
638 or not. This configurable formatting was employed to flexibly
639 support accessing multiple nicknames from the user interface.
640 The userinterface can now set the nicknames to what ever format
641 they prefer. Affected file lib/silcclient/silcapi.h.
643 Added function silc_client_nickname_format to the file
644 lib/silcclient/idlist.c. It performs the nickname formatting.
646 Added new field `hostname´ to the SilcClientEntry context.
647 It holds the hostname of the client. Affected file is
648 lib/silcclient/idlist.h.
650 * Irssi SILC Client sets the nicknames in nick@hostn format.
651 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
652 irssi/src/silc/core/silc-core.c.
654 The WHOIS printing now also shows both the real nickname and
655 the formatted nickname so that user knows how to access the
656 user if there are multiple same nicknames cached. Affected
657 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
658 printing formatting too to take the hostname now as a separate
659 argument. The Affected file is
660 irssi/src/fe-common/silc/modules-formats.[ch].
662 * Changed the silc_client_get_clients_local to accept the formatted
663 nickname as argument. It accepts the real nickname too but the
664 formatted nickname can be used to find the true entry from
665 multiple entries. Affected file lib/silcclient/silcapi.h and
666 lib/silcclient/idlist.c.
668 * Added nickname_format_parse field to the SilcClientParams.
669 It is a callback function provided by the application to parse
670 the nickname out of the formatted nickname string. The library
671 calls it to get the nickname from the formatted string. Since
672 the application generally knows better the format of the nickname
673 string it parses it instead of the library, even though library
674 encodes the formatted string. If the callback function is not
675 provided then the library will use the string as is. The
676 affected file is lib/silcclient/silcapi.h.
678 * All the nickname strings passed to the client library in
679 commands are now expected to be formatted nickname strings.
680 If the command does not support the formatted nickname string
681 it will assume that the sent string is the actual nickname.
682 Affected file lib/silcclient/command.c.
684 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Added public key authentication support to OPER and SILCOPER
687 commands in the client library. Affected file is
688 lib/silcclient/command.c.
690 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Changed the get_auth_methdod client operation to be asynchronous.
693 It can be async if the application resolves the authentication
694 method from the server during the negotiation. Added new
695 SilcGetAuthMeth completion callback that the application will
696 call after resolving the authentication method.
698 Added function silc_client_request_authentication_method that
699 the application can use to resolve the authentication method
700 from the server. Added also SilcConnectionAuthRequest callback
701 that the library will call after the server has replied. The
702 application can call this function if it does not know the
703 current authentication method.
705 Affected files are lib/silcclient/client.c and
706 lib/silcclient/silcapi.h.
708 * The Irssi SILC client now automatically resolves the authentication
709 method incase any configuration information is not present (and
710 currently there never is). The affected file is
711 irssi/src/silc/core/client_ops.c.
713 * Fixed public key authentication from the client library.
714 Affected file lib/silcclient/protocol.c. Changed also the
715 protocol specification about the public key authentication in
716 the connection authentication protocol. The actual data to be
717 signed is now computed with a hash function before signing.
719 * Fixed the public key authentication from the server as well.
720 Affected file silcd/protocol.c.
722 * Removed the mlock()'s from the memory allocation routines.
723 Affected file lib/silcutil/silcmemory.c. The ./configure does
724 not check anymore for the mlock(). Affected file is
727 * Fixed USERS command in server to allow the execution of the
728 command for private and secret channels if the client sending
729 the command is on the channel. Affected file silcd/command.c.
731 * Fixed silc_client_get_clients_local to return the clients
732 count correctly. It could return wrong value. Affected file
733 lib/silcclient/idlist.c.
735 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
738 types. The assembler optimizations seemed not to like 64-bit
739 data types. The assmebler optimizations thus are now enabled
740 also for BSD systems as opposed to only enable them for Linux.
742 * Do not check for threads at all on BSD systems. Affected
743 file configure.in.pre.
745 * Removed -n and -h options from the Irssi SILC Client since
746 they are not used in silc.
748 * Fixed the prime generation to assure that the first digit
749 of the generated random number is not zero since our conversion
750 routines does not like number strings that starts with zero
751 digit. If zero digit is seen the random number is regenerated.
752 This caused some corrupted RSA keys when the zero first digit
753 was met. Affected file lib/silcmath/silcprimegen.c.
755 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Fixed WIN32 configuration in the ./configure script.
758 Fixed to include xti.h on environments that has it.
759 Patches by Carsten Ilchmann and andrew.
761 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
763 * Changed the silc_id_create_client_id to be collision
764 resistant. It is now assured that there cannot be created
765 two same client ID's. I suspect that some weird bugs in
766 the server were actually caused by duplicate Client IDs.
767 Affected file silcd/serverid.[ch]. A router receiving
768 new ID now also assures and informs the sending server
769 if the ID caused collision.
771 * Changed the silc_id_create_channel_id to also assure that
772 there are no collisions.
774 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
776 * Statement about ignoring the Mutual Authentication flag when
777 performing rekey with PFS was a bit misleading. It is ignored
778 if it was set in the initial negotiation, it cannot be even
779 set in the rekey. Fixed in the ke-auth draft. Started the
780 new versions of the protocol drafts in the doc/.
782 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
784 * Fixed a bug in silc_client_command_identify_save when saving
785 new channel information. The channel name was no duplicated
786 and caused crash on exit. Affected file is
787 lib/silcclient/command_reply.c.
789 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
791 * Fixed the getkey command handling in the server. Send just
792 empty OK reply to the sender if the key could not be fetched
793 (but everything else was ok, like the key just was not available).
794 Changed the public key parameter to optional in the protocol
795 specs so that empty OK reply can be sent. Affected file
798 Added a message to Irssi SILC client to tell to user if the
799 server did not return a public key.
801 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
803 * Fixed a channel key regeneration bug. It registered new
804 timeout tasks exponentially until all system resources were
805 used. Affected file silcd/server.c.
807 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Added the SILC Document generator to the scripts/silcdoc.
810 It can be used to generate the Toolkit Reference Manual out
811 of the source tree. Internally it will also use the RoboDoc
812 generator now imported in util/robodoc.
814 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Added couple of return's in rekey protocol if error orccurred
817 during the protocol. The execution must be terminated.
818 Affected file silcd/protocol.c. Also, terminate the protocol
821 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
823 * The client's Client ID was created initally from the wrong
824 nickname (it could have been in format nick@host) in the
825 silc_server_new_client. Affected file silcd/packet_receive.c
827 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Added some SILC_LOG_ERROR's to various error conditions
830 if client could not be added to ID cache. Affected files
831 silcd/packet_receive.c and silcd/server.c.
833 * When client's sock->user_data is freed, NULL also the
834 client->router and client->connection pointers. Added check
835 for these pointers being NULL to various places around the
836 code. Affected file silcd/server.c.
838 * Added client->data.registered == TRUE checks to various
839 places around the code to assure that unregistered client's
840 are not handled when it is not allowed. Affected file
843 * Added `bool registered' fields to all
844 silc_idlist_[server|client]_get_* routines to indicate whether
845 the fetched client needs to be registered or not. Affected
846 file silcd/idlist.[ch].
848 * Add your own entry as registered to the ID cache in the
849 server. Affected file server.c.
851 * Fixed a bug in silc_server_new_server. The SilcServer was
852 set as the new server's context instead of SilcServerEntry.
853 This naturally caused some weird bugs.
855 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Do not delete the channel rekey task when adding it
858 for in silc_server_create_channel_key.
860 * Changed the silc_server_create_channel_key to return
861 TRUE or FALSE to indicate the success of the channel key
864 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Fixed MSVC++ project files and added missing files to
867 Makefiles under win32/.
869 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Do not add TCP_NODELAY flag if the operating system
872 does not have it defined. Affected files are
873 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
875 * Fixed buffer overflow from Irssi SILC Client. Affected
876 file irssi/src/fe-common/core/themes.c.
878 * Fixed double free in client library in the file
879 lib/silcclient/client.c when disconnecting from server.
881 * Applied double free patch from cras to Irssi SILC client.
882 Affected files irssi/src/core/[modules/expandos].c
884 * Fixed the disconnection handling to Irssi SILC Client.
885 The application must call silc_client_close_connection
886 in ops->connect client operation in case of failure of
887 the connection. Affected file is
888 irssi/src/silc/core/client_ops.c.
890 * Do not set sock->protocol to NULL in the function
891 silc_client_close_connection after executing the protocol's
892 final callback since the sock might not be valid anymore.
893 Affected file lib/silcclient/client.c.
895 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Do not enable SILC_THREADS if the linking with libpthread
898 did not happen. Affected file configure.in.pre.
900 * Added notion to protocol specification that server must
901 verify the sent authentication payload with CMODE when
902 setting the channel founder key. Implemented it to the
903 server. Affected file silcd/command.c.
905 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Added _EXTRA_DIST SILC distribution variable to the
908 distributions file. It is used to conditionally add extra
909 files or directories to the specific distribution. Affected
910 files ./prepare, Makefile.am.pre and distributions.
912 Removed the `_' from the start of the distribution names.
915 * Added README.WIN32 for instructions to compile the Toolkit
918 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Fixed a double free in disconnection in the server. Affected
921 file is silcd/server.c.
923 * Fixed the lib/silcske/groups.c to work now also with GMP
924 MP library. The string conversion did not work when using
925 specific base and the base is indicated in the string as well.
927 * Created win32/ directory which now includes MSVC++ specific
928 stuff so that toolkit (DLLs) may be compiled with MSVC++.
929 It will appear only in the toolkit distribution
931 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
933 * Changed the key material distribution function in case when
934 the hash output is too short. The data is now concatenated
935 a bit differently than it used to. Made the change to the
936 SKE protocol specification.
938 * Added better GMP detection to configure.in.pre. A patch
941 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
943 * Fixed a minor bug in SKE that might cause some problem on
944 some platforms. Affected file lib/silcske/silcske.c.
946 * Added the cookie checking for initiator in the SKE. It checks
947 that the responder returns the sent cookie unmodified. The
948 affected file is lib/silcske/silcske.c. Added new SKE
949 error type INVALID_COOKIE that can be sent during the
950 negotiation. Fixed some memory leaks as well.
952 * Added the "invalid cookie" error message to Irssi SILC client's
955 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
957 * Added `task_max' field to the SilcClientParams to indicate
958 the maximum tasks the scheduler can handle. If set to zero,
959 default values are used. Affected file lib/silcclient/silcapi.h.
961 * Fixed memory leaks in silc_client_close_connection. Affected
962 file lib/silcclient/client.c.
964 * Added silc_client_del_client_entry to client library to free
965 all memory of given client entry. Affected file is
966 lib/silcclient/idlist.[ch].
968 * Added new functions silc_client_del_channel and
969 silc_client_del_server to delete channel and server entries.
970 Affected file lib/silcclient/[silcapi.h/idlist.c].
972 * Removed silc_client_del_client_by_id from silcapi.h.
974 * Fixed the INFO command to return the server's own info
975 correctly when querying by Server ID. Affected file is
978 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Removed the non-blocking settings in WIN32 code in the
981 silc_sock_[read/write] and added SleepEx instead. Affected
982 file lib/silcutil/win32/silcwin32sockconn.c. The availability
983 of input data is now checked with FIONREAD and ioctlsocket.
985 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
987 * Call silc_schedule_task_del_by_context in the
988 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
989 Affected file lib/silccore/silcprotocol.c.
991 * Call silc_protocol_cancel for active protocols in the
992 silc_server_close_connection if the funtion
993 silc_server_free_sock_user_data has not been called.
994 Affected file silcd/server.c.
996 * Generic tasks cannot be deleted using the del_by_fd
997 task deleting function since generic tasks does not match
998 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1000 * Added a notion to SILCOPER help file that the SILCOPER works
1001 only on router server, not on normal server.
1003 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Added for WIN32 support for the new scheduler as well.
1006 Affected file lib/silcutil/win32/silcwin32schedule.c.
1008 * Fixed the SHA1 implementation to work on various platforms.
1010 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1013 API. It is part of the scheduler now. Everything else is
1014 as previously but some functions has changed their names.
1015 Checkout the lib/silcutil/silcschedule.h for the interface.
1016 Updated all applications to use the new interface. Affected
1017 files are lib/silcutil/silcschedule.[ch].
1019 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Found a bug in the SKE implementation. The HASH value,
1022 specified by the protocol, was not computed correctly. The
1023 public key of the responder was not added to the computation
1024 even though it is mandatory. Affected file lib/silcske/silcske.c.
1025 This unfortunately causes incompatibilities with older
1026 clients and servers.
1028 * Added WIN32 specific network init and uninit functions:
1029 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1030 the Winsock2. Affected file lib/silcutil/silcnet.h and
1031 lib/silcutil/win32/silcwin32net.c.
1033 * Set the socket always to nonblocking mode on WIN32 after
1034 reading data or writing data. Affected file is
1035 lib/silcutil/win32/silcwin32sockconn.c.
1037 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1039 * Fixed various compilation problems under WIN32. Affected
1040 files lib/silcutil/win32/silcwin32thread.c and
1041 lib/silcutil/win32/silcwin32schedule.c.
1043 * Removed all _internal.h #includes from public header
1044 files. Internal headers must never be included from
1047 Removed also the lib/silcske/payload_internal.h file.
1049 * All include files that may be needed (public and some others
1050 included by the public headers) by application developers are
1051 now copied to the ./includes directory. It does not copy any
1052 internal headers. Affected file Makefile.defines.pre and all
1053 Makefile.am's under lib/ and subdirs.
1055 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1057 * Do not change the ~/.silc directory's permissions automatically.
1058 Affected file irssi/src/silc/core/clientutil.c.
1060 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Do not cancel the protocol in silc_server_close_connection
1063 it might cause recursion. Now cancelled in the function
1064 silc_server_free_sock_user_data. Affected file silcd/server.c.
1066 * Fixed the silc_server_remove_clients_by_server to regenerate
1067 the channel keys correctly finally. Added also new function
1068 silc_server_remove_clients_channels to actually do it.
1069 Affected file silcd/server.c.
1071 * Fixed the silc_server_new_channel to not crash by giving
1072 wrong router to the new channel. Affected file is
1073 silcd/packet_receive.c.
1075 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1078 which is given as argument to the silc_client_alloc now.
1079 It can be used to configure the client and set various parameters
1080 that affect the function of the client.
1082 * The USERS command in server did not check whether the channel
1083 is private or secret. Affected file silcd/command.c.
1085 * Added new argument to the USERS command in protocol specification.
1086 The USERS command now can take the channel name as argument
1087 as well. Added support for this in client and server and
1088 updated the protocol specs.
1090 * Completed the GETKEY command in client. It can be now used
1091 to fetch also servers public key not only some clients.
1092 Affected files lib/silcclient/command[_reply].c.
1094 * Added silc_client_get_server to return server entry by the
1095 server name. Affected files lib/silcclient/silcapi.h and
1098 * Redefined the IDENTIFY command in protocol specification to be
1099 more generic. It now can be used to query information about
1100 any entity in the SILC Network, including clients, servers and
1101 channels. The query may be based either the entity's name
1102 or the ID. Added support for this in both client and server.
1104 Affected files silcd/command.c and lib/silcclient/command.c
1105 and command_reply.c.
1107 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1108 the _from_client and _from_server functions. Affected file
1111 * Added silc_client_get_channel_by_id_resolve to the file
1112 lib/silcclient/silcapi.h to resolve channel information by
1113 its ID. Added also silc_client_get_channel_by_id that
1114 does not resolve it from the server.
1116 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Added SilcServerEntry context into the client library
1119 to represent one server. The INFO command now allocates
1120 these to save the resolved server info. For now on the
1121 client library will also keep information about servers,
1122 connected and resolved with INFO.
1124 The INFO command now allocates the SilcServerEntry context
1125 and saves the server info there. The COMMAND_REPLY in
1126 the INFO now returns the parameters to application in
1127 same order as defined in the protocol specification.
1129 The entries are cached in the client->server_cache.
1131 * The INFO command is now issued after received the Client ID
1132 from the server. Affected file lib/silcclient/client.c.
1134 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1135 to the application as the mode changer might be server.
1136 It is guaranteed that NULL is not returned anymore to the
1137 application. Affected file lib/silcclient/client_notify.c.
1139 The ID Type is now also passed to the application so that
1140 it can check whether the returned entry is SilcClientEntry
1143 Added new function silc_client_get_server_by_id to return
1144 the server entry by ID. Affected files are the
1145 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1147 * Do not create the channel in the Irssi SILC Client when issuing
1148 the JOIN command but when received the sucessful JOIN command
1149 reply. Otherwise the channel might get created even though we
1150 could not join it. The Affected file is
1151 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1153 * Fixed a channel joining bug in router. The router must also
1154 check the channel modes, invite and ban lists etc. when serving
1155 the JOIN command sent by normal server. Affected file is
1156 silcd/command.c. The router now resolves the client's
1157 information from the server who sent the JOIN command if it
1158 does not know it, and processes the JOIN command only after
1161 * Changed the SilcCommandCb to take new argument; void *context2.
1162 Affected file lib/silccore/silccommand.h
1164 The second argument in the command callbacks in the server now
1165 includes the SilcServerCommandReplyContext if the command was
1166 called as pending command callback from the command reply.
1167 Otherwise it is NULL. When called as pending the status of the
1168 command reply will be checked and if it was erronous the
1169 error will be sent to the original sender of the command.
1170 This way the client always receives the error messages even
1171 though the server was actually the one who received the error
1172 when it resent the command to router, for example. Affected
1173 files silcd/command[_reply].[ch].
1175 * Fixed sending WHOWAS command's error message to client if
1176 the requested client could not be found. It was missing.
1179 * Changed the CMODE and CUMODE commands reply arguments in the
1180 protocol specification. The Channel ID is now sent in both
1181 of the commands to identify the channel. Implemented this
1182 new feature to the client and server. Affected files
1183 lib/silcclient/command_reply.c and silcd/command.c.
1185 * Made better checks for invite and ban lists in the JOIN
1186 command in server. Affected file silcd/command.c.
1188 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * The server now performs the incoming host IP/DNS lookup
1191 using the silc_socket_host_lookup and thus does not block
1192 the server anymore. Affected file silcd/server.c.
1194 * Completed the multi-thread support for SILC Scheduler in
1195 the lib/silcutil/silcschedule.c.
1197 * Fixed the configure.in.pre to detect the pthread correctly
1200 * Fixed a deadlock in silc_task_queue_wakeup in the file
1201 lib/silcutil/silctask.c.
1203 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Added new function silc_schedule_wakeup that is used in
1206 multi-threaded environment to wakeup the main thread's
1207 schduler. It needs to be used when a thread adds a new task
1208 or removes a task from task queues. After waking up, the
1209 scheduler will detect the task queue changes. If threads
1210 support is not compiled in this function has no effect.
1211 Implemented the wakeup mechanism to both Unix and WIN32
1212 systems. Affected files are lib/silcutil/silcschedule.[ch],
1213 lib/silcutil/unix/silcunixschedule.c and the
1214 lib/silcutil/win32/silcwin32schedule.c.
1216 * Added new function silc_task_queue_wakeup to wakeup the
1217 scheduler by the specified task queue. Affected file
1218 lib/silcutil/silctask.[ch].
1220 * The silc_socket_host_lookup_start now wakes up the scheduler
1221 after adding the timeout task. Affected file is
1222 lib/silcutil/silcsockconn.c.
1224 * The silc_socket_host_lookup is synchronous now if the threads
1225 support is not compiled in. However, the callback is still
1226 called asyncronously through the scheduler, anyway. Affected
1227 file lib/silcutil/silcsockconn.c.
1229 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1231 * Added new function silc_socket_host_lookup to perform
1232 asynchronous IP and FQDN lookups for the socket connection.
1233 Affected files lib/silcutil/silcsockconn.[ch].
1235 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1238 that may or may not compile the mutex support in.
1240 Changed the silc_mutex_alloc interface. It allocates the
1241 mutex now to the sent pointer and returns TRUE or FALSE.
1243 Affected file lib/silcutil/silcmutex.h.
1245 * Wrote the SILC Task Queue interface to support multi-threads.
1246 Affected file lib/silcutil/silctask.[ch].
1248 * Wrote the SILC Scheduler to support multi-threads. Affected
1249 file lib/silcutil/silcschedule.c.
1251 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1254 in lib/silcutil/win32/.
1256 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Defined SILC Mutex API and SILC Thread API and implemented
1259 them for Unix. Affected files are
1260 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1261 lib/silcutil/unix/silcunixmutex.c and
1262 lib/silcutil/unix/silcunixthread.c.
1264 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Fixed the silc_server_remove_clients_by_server's channel
1267 key re-generation. The hash table handling was incorrect
1268 and would not work with many channels. Affected file is
1271 * Fixed some memory leaks around the server code.
1273 * Rewrote the silc_server_get_users_on_channel to support IPv6
1274 based Client ID's. Affected file silcd/server.c.
1276 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1277 specification. However, a separate document must be written
1278 to define the detailed signing procedure and the payload
1279 associated with the flag. Defined the flag to the
1280 lib/silccore/silcchannel.h as well.
1282 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Changed the dynamic tables to static size tables in the
1285 lib/silccrypt/silchmac.c.
1287 * Removed GCC dependencies from the code. A patch by cras.
1289 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * Do not show the error "Error receiving packet bla bla"
1292 in server if it really was not an error (-2 means that reading
1293 is pending). Affected file silcd/server.c.
1295 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Fixed a possible crash in silc_server_remove_clients_by_server
1298 in silcd/server.c. Fixed there also some memory leaks.
1300 * Fixed the silc_idlist_replace_client_id. It could replace
1301 wrong key in the hash table. Affected file silcd/idlist.c.
1303 * Do not check whether there are global users on the channel
1304 if the channel->global_users is FALSE. Affected functions
1305 silc_server_remove_from_one_channel and
1306 silc_server_remove_from_channels in silcd/server.c. Also,
1307 do not check if the removed client is local as we can be
1308 sure that global client was not removed from the channel
1309 and checking for global users is not needed.
1311 * The silc_server_remove_clients_by_server now re-generates
1312 the channel keys correctly for those channels that had
1313 clients removed from them. Affected file silcd/server.c.
1315 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Found the reason of random crashes in the server. We weren't
1318 ignoring the SIGPIPE signal (which can be sent in write())
1319 and it crashed the server. Affected file silcd/silcd.c.
1321 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Assure that sock->user_data is not NULL in the function
1324 silc_server_packet_send in silcd/packet_send.c.
1326 * Disconnect the remote connection if it could not be added
1327 to any ID lists in the server. The affected file is
1330 * Check in silc_server_packet_send[_real/dest] that the
1331 socket is not disconnecting and ignore the data if it is.
1332 Affected file silcd/packet_send.c.
1334 * Define inline to __inline on native WIN32 compilation.
1335 Affected file includes/silcwin32.h.
1337 * Added some explicit type casts for inline code since MSVC
1338 require them. Affected files lib/silcutil/silcbuffer.h,
1339 lib/trq/silcdlist.h and lib/trq/silclist.h.
1341 * Print warning in log files from now on if the packet
1342 decryption fails. Affected file silcd/server.c.
1344 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Changed the `say' client operation's interface to accept
1347 new `type' argument to indicate the type of the message sent
1348 by the library. The application may filter the library's
1349 messages according the type. The affected file is the
1350 lib/silcclient/silcapi.h.
1352 * Added two new functions to lib/silcclient/silcapi.h:
1353 silc_client_del_client and silc_client_del_client_by_id.
1354 Affected file lib/silcclient/idlist.c.
1356 * Moved the clientincludes.h from includes/ to silc/ and
1357 serverincludes.h from includes/ to silcd/.
1359 * The modes for the CMODE and CUMODE are now passed as
1360 uint32 for application with COMMAND_REPLY. The affected
1361 file is lib/silcclient/command_reply.c.
1363 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * /WHOIS without arguments shows client's own information.
1366 Affected file lib/silcclient/command.c.
1368 * Changed PING to not accept any arguments. The specs
1369 says that client can ping only the connected server so
1370 requiring an argument is not needed. Affected file is
1371 lib/silcclient/command.c.
1373 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Fixed a fatal bug in private message sending and reception
1376 encryption and decryption when using private message keys.
1377 The implementation was incorrect and did not follow the
1378 specification. It causd that some of the message were
1379 lost since it did not use the sending and receiving keys
1380 as the protocol suggests. This has been fixed and will cause
1381 incompatibilities with older clients when sending private
1382 message encrypted with private message keys. Affected files
1383 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1384 and various other in Irssi SILC Client.
1386 Added `responder' boolean argument to the functions
1387 silc_client_add_private_message_key[_ske] to indicate when
1388 the key is added as responder or initiator of the key
1391 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Removed the silc_ske_check_version function and created
1394 a SilcSKECheckVersion callback. Added also a function
1395 silc_ske_set_callbacks that is now used to set all SKE
1396 callbacks. The callback functions are not given to
1397 the SKE functions anymore, but this function is used to
1400 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1402 * Added `silc_version' argument to the silc_client_alloc
1403 to define the version of the application for the library.
1404 The library will use the version string to compare it
1405 against the remote host's (usually a server) version
1406 string. Affected file lib/silcclient/silcapi.h
1408 * Added the KE protocol context to Key Agreement context
1409 in client library so that we can abort the SKE if it
1410 is in process when we get timeout. Affected file is
1411 lib/silcclient/client_keyagr.c.
1413 * Do not resolve the client ID forever if it returns in the
1414 first time that such client does not exist. This was done
1415 for example with private message. Affected file is
1416 lib/silcclient/client_prvmsg.c.
1418 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Do not add regex.h for WIN32. The affected file
1421 includes/silcincludes.h.
1423 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1424 not work yet 100%. It generates the DLL's automatically
1425 when compiling with --with-win32 under cygwin.
1427 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * lib/contrib/regex.c is not compiled on WIN32.
1431 * Added silc_net_get_socket_opt function to the
1432 lib/silcutil/silcnet.h.
1434 * Added includes/silcwin32.h for WIN32 specific includes
1437 * Do not use ptime structure or any of the posix process
1438 functions on WIN32 in lib/silccrypt/silrng.c.
1440 * Added silc_gettimeofday to provide generic function
1441 for struct timeval on all platforms. Added the function
1442 to lib/silcutil/silcutil.h.
1444 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1447 library as they clearly belong there. As a plus side we
1448 can make the actual socket connection routines platform
1451 Added also new generic function silc_socket_read and
1452 silc_socket_write (that used to be silc_packet_[read/write].
1453 The implementation of these are platform specific.
1455 * Added WIN32 specific routines of silc_socket_[read/write]
1456 to lib/silcutil/win32/silcwin32sockconn.c.
1458 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Added preliminary support for native WIN32 compilation under
1461 cygwin (using the -mno-cygwin option for GCC) to the
1462 ./configure.in.pre. The --with-win32 now prepares the
1463 compilation for native WIN32.
1465 * Rewrote the SILC Scheduler interface in the file
1466 lib/silcutil/silcschedule.h. The scheduler is now context
1467 based and does not have anymore any global static scheduler.
1468 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1469 and created lib/silcutil/win32 directory for WIN32 based
1472 * Added Unix specific network routines to the
1473 lib/silcutil/unix/silcunixnet.c and the old
1474 lib/silcutil/silcnet.c includes now only generic routines.
1476 Added WIN32 specific network routines to the
1477 lib/silcutil/win32/silcwin32net.c.
1479 * Added Unix specific utility functions from the
1480 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1482 * Added WIN32 SILC Scheduler to the file
1483 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1486 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Do not handle JOIN notify in the server if the target client
1489 is not registered (idata->registered == FALSE). The affected
1490 file is silcd/packet_receive.c.
1492 * Update the nickrec->founder in event_cumode in the Irssi SILC
1493 client. Affected file irssi/src/silc/core/silc-channels.c.
1495 * Fixed the CUMODE_CHANGE notify handling in the server when
1496 server and router are announcing their clients on channels.
1497 Now the mode changes are saved and notified correctly. The
1498 affected file is /silcd/packet_receive.c.
1500 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1501 They really did not replace the cache entry in the ID Cache.
1502 Now they do that. Affected file silcd/idlist.c.
1504 * Fixed the KICK notify handling in the Irssi SILC client to
1505 update the channel records so that the kicked client does not
1506 appear to be on the channel. The affected file is
1507 irssi/src/silc/core/silc-channels.c.
1509 * Always update the conn->current_channel when executing command
1510 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1512 * Fixed the KILL notify handling in Irssi SILC client to remove
1513 the killed client on all channels.
1515 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Fixed the silc_parse_command_line to remove extra spaces
1518 from the start and end of the arguments. Affected file is
1519 lib/silcutil/silcutil.c.
1521 * Cancel and free any active protocol in the function
1522 silc_server_close_connection. Affected file silcd/server.c.
1524 * Cancel and free any active protocol in the function
1525 silc_client_close_connction. Affected file is
1526 lib/silcclient/client.c.
1528 * Do not execute the KILL command for clients that are in
1529 history (ie. they are not in the network). Affected file is
1532 * Fixed KILL notify handling, client does not crash anymore.
1533 Affected file irssi/src/silc/core/silc-channels.c.
1535 * Reduced the default packet buffer size from 2048 to 1024 in
1536 lib/silccore/silcpacket.c.
1538 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1539 counter to the SKE context that is incresed when the SKE library
1540 performs async operation outside the library. If the outside
1541 process frees the SKE context and FREED status will be set
1542 and the library will detect after the sync operation that the
1543 libary is freed. The affected files are
1544 lib/silcske/silcske[_status].[ch].
1546 * Resolve the client entry information in the function
1547 silc_client_channel_message to assure that NULL pointer is not
1548 passed as client entry to the application. */
1550 * Fixed the task timeout calculation to assure that there is
1551 never negative timeouts. The affected file is
1552 lib/silcutil/silcschedule.c.
1554 * Fixed the channel user mode notification sending in server.
1555 It was sent point-to-point to the router (or to server by router)
1556 but it needs to be destined to a channel. The routines now
1557 supports sending the channel user mode notifys to the channels
1558 when announcing clients and channels. Affected files are
1559 silcd/server.c and silcd/packet_receive.c.
1561 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1562 It did not actually replace the old channel entry in the cache.
1563 Affected file lib/silcclient/client_notify.c.
1565 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1567 * Fixed a possible crash in silc_packet_send_prepare. It now
1568 assures always that there is enough space in the buffer and
1569 at the tail area of the buffer (for MAC).
1571 Fixed the inbound buffer reallocation in silc_packet_read.
1572 It was old code and did not handle the reallocation correctly.
1575 The affected file is lib/silccore/silcpacket.c.
1577 * Fixed buffer overflow in silc_parse_nickname in the file
1578 lib/silcutil/silcutil.c.
1580 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * make install generates new server keys only if there is not
1585 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1588 Added check that if the NOREPLY is set then we will not send
1589 the away message. This avoids infinite loop of away messages
1590 if both clients are away. The affected file is
1591 lib/silcclient/client_prvmsg.c.
1593 * Fixed client crash if /NICK was given without arguments.
1594 Affected file lib/silcclient/command.c.
1596 * Server does not send the invite list in INVITE command back
1597 to the client if the list was not altered. Added this notion
1598 to the protocol spec as well. Affected file silcd/command.c.
1600 Fixed possible crash in INVITE command by checking the
1601 value of silc_server_get_client_route command.
1603 * Fixed the INVITE notify type handling. The arguments are now
1604 taken in correct order and client does not crash. The affected
1605 file is irssi/src/silc/core/silc-channels.c.
1607 Removed the "Inviting xxx to channel" message from the
1608 client library away and let the application handle it.
1609 Affected file lib/silcclient/command.c. Added that message
1610 to Irssi SILC client's message formats.
1612 * Fixed CMODE command crash in client. It now checks the
1613 amount of arguments correctly and does not crash. The affected
1614 file is lib/silcclient/command.c.
1616 * Do not create new channel automatically in silc_channels_join
1617 but check whether the channel by that name already exists.
1618 Affected file irssi/silc/core/silc-channels.c.
1620 * Do not send the SERVER_SIGNOFF to router if the disconnected
1621 entity was the router. Affected file silcd/server.c.
1623 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1624 SILC client as it was missing from there.
1626 Added the handling of the KICK notify to the Irssi SILC client
1627 as it was missing. Added "you have been kicked" message to
1628 Irssi SILC client's message modules formats.
1630 Added the handing of the KILL notify to the Irssi SILC client
1631 as it was missing. Added the kill message module formats
1634 The affected file is irssi/src/silc/core/silc-channels.c.
1636 * The router did not save the channel mode the server announced.
1637 Affected file silcd/packet_receive.c.
1639 * Fixed a possible crash in INFO command in server. If the
1640 server did not provide the server info it crashed. Affected
1641 file silcd/command.c.
1643 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Fixed the GETKEY command in the server to check also the
1646 global list. Otherwise the GETKEY would not work correctly
1647 in normal SILC server. Affected file silcd/command.c.
1649 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Fixed GETKEY crash, it crashed if the command did not succseed.
1653 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1656 is now real and not just an macro interface to GMP.
1658 Removed the entire GMP from the source tree and imported new
1659 NSS MPI library instead. Reason for removing GMP is that it is
1660 extremely large and compiles extremely slow. The NSS MPI
1661 is only a few files and compiles in less than 10 seconds.
1662 The speed is also about the same as GMP. The MPI is imported
1663 to lib/silcmath/mpi.
1665 If the system has GMP installed we will still use the GMP.
1666 If it is not then the NSS MPI will be compiled.
1668 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1670 * Merged a long nickname (127 characters long) crash bugfix from
1671 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1673 * Merged a freed memory reference bugfix from Irssi CVS tree.
1674 Affected file irssi/src/core/commands.c.
1676 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1678 * Added the server's public key sving and verification to the
1679 server when performing the SKE. This was missing and the
1680 remote server's (or router's) public key was accepted without
1681 checking whether we have it previously or trust it at all.
1682 Affected file silcd/protocol.c.
1684 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1686 * Check in the silc_server_timeout_remote if protocol is active
1687 and make sure that the protocol's final callback is called so
1688 that all memory if freed. Affected file silcd/server.c.
1690 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * silc_server_whois_send_reply crashed the server if the nickname
1693 was 127 characters long. Affected file silcd/command.c.
1695 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Added sanity check to the silc_server_new_client. If the hostname
1698 is provided inside username then check that the provided hostname
1699 really is the same as the resolved one. If the hostname was not
1700 resolved then check it from the public key. Affected file is
1701 silcd/packet_receive.c.
1703 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1704 if the server disconnected us and the connection is not valid
1705 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1707 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1708 the library to the lib/silcutil/silcutil.[ch].
1710 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1712 * Close log file after open. Affected file
1713 lib/silcutil/silclog.c.
1715 * Check whether sock == NULL in silc_client_send_packet and return
1716 if it is. Affected file lib/silcclient/silcclient.c.
1718 * Check rec->entry == NULL in the Irssi SILC Client before
1719 sending the channel message. Affecte file is
1720 irssi/src/silc/core/silc-servers.c.
1722 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1724 * Merged a splitted window bugfix from Irssi CVS tree. The
1725 affected file is irssi/src/fe-text/textbuffer-view.c.
1727 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1728 It did not print nickname.
1730 * Improved the distributions system a bit.
1732 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1735 irssi/src/fe-text/gui-window.c.
1737 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1738 to in-active server. The affected file is
1739 irssi/src/silc/core/client_ops.c.
1741 * Resolve the client in USERS command reply if the entry does
1742 not have username resolved. The affected file is
1743 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1744 command to WHOIS command to really resolve stuff. The USERS
1745 is not used any more in any critical section so WHOIS can
1746 be used even though it might be slower than IDENTIFY.
1748 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1751 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Changed the protocol API a bit more consistent in the
1754 lib/silccore/silcprotocol.[ch].
1756 * Changed the following headers to ROBODoc format:
1758 lib/silccore/silcpayload.h
1759 lib/silccore/silcprotocol.h
1760 lib/silccore/silcsockconn.h
1762 All core library headers are now formatted.
1764 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Fixed a bug in Irssi SILC client; do not show that you are
1767 server/router operator if you really are not. Affected file is
1768 irssi/src/silc/core/client_ops.c.
1770 * Renamed silc_command_free_payload to silc_command_payload_free.
1771 Affected file lib/silccore/silccommand.h
1773 * Added silcmath.h to include the prototoypes of various routines
1774 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1777 * Changed the following headers to ROBODoc format:
1779 lib/silccore/silcchannel.h
1780 lib/silccore/silccommand.h
1781 lib/silccore/silcid.h
1782 lib/silccore/silcidcache.h
1783 lib/silccore/silcmode.h
1784 lib/silccore/silcnotify.h
1785 lib/silccore/silcpacket.h
1786 lib/silcmath/silcmath.h
1788 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1790 * Added checking to the server code not to start the server if
1791 ciphers and stuff are not configured properly. Affected files
1792 silcd/serverconfig.[h] and silcd/server.c.
1794 * Changed the layout of the header files of the public interfaces
1795 in the SILC libraries. The new layout supports ROBODoc
1796 documentation tool (and some others) so that it is easy to create
1797 a library reference manual. All the other headers and source
1798 code must still follow the CodingStyle document. Also source
1799 code must not include these ROBODoc stuffs, only the headers.
1800 Furthermore, all public interface headers must now be named
1801 by using `silc' prefix, example: silcapi.h, silccipher.h.
1802 Some files were renamed due to this. All the other headers
1803 must not be used as public interfaces. I will update the
1804 CodingStyle document later. Changed following headers, so far:
1806 lib/silcclient/silcapi.h
1807 lib/silccore/silcauth.h
1808 lib/silccore/silcprivate.h
1809 lib/silccrypt/silcdh.h
1811 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Removed silc_client_packet_send_flush from the client library
1816 as it is not needed. Affected file lib/silcclient/client.[ch].
1818 * Added printing of message of unresolved authentication method
1819 to the Irssi SILC client. Added it to the module formats.
1820 Removed the same message from the client library.
1822 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Added new distribution feature, DISTLABEL. Every distribution
1825 can define own preprocessor label that can be used in the
1826 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1827 file distributions, acconfig.h.pre and prepare.
1829 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Added Makefile.defines_int to include the actual definitions
1832 for Makefile.defines.in. Tested the new distribution system,
1833 created distributions and tested installation.
1835 * Added AWAY message printing to the Irssi SILC client. Added
1836 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1838 * Added SCONNECT command to call the SILC's CONNECT command.
1839 Cannot use CONNECT directly since Irssi uses that internally.
1840 Affected file irssi/src/silc/core/silc-servers.c.
1842 Added ACTION local command. It is same as ME command but takes
1843 the channel as mandatory argument.
1845 Rewrote some of the Irssi's help files to suite for SILC
1848 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Added Makefile.defines[.in] that should for now on be included
1851 in all Makefile.am file in the source tree. That file includes
1852 all common compilation definitions for SILC source tree.
1854 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Minor changes to the ./prepare script to change the package
1857 name according the distribution name to the configure.in.
1859 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Created new distribution system. Added file `distributions'
1862 that defines all the distributions that can be created out of
1863 the SILC source tree. The ./prepare script now reads that
1864 file to determine how to prepare the distributions. The
1865 first argument to the ./prepare is the name of the distribution
1866 and second is the version of the distribution. If given
1867 without arguments it creates the default (toolkit) distribution
1868 with the default version (defined in ./prepare).
1870 All Makefile.am files that are subject to the distributions
1871 are now named as Makefile.am.pre. These are ./Makefile.am
1872 and lib/Makefile.am. Others may be changed later.
1874 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1876 * Added invite list, ban list, some key management and connection
1877 error message printing to module formats in the Irssi SILC client.
1879 * Added new silc_client_set_away_message to set the away message
1880 that is back to the person who sent private message. The
1881 affected file lib/silcclient/silcapi.h and the
1882 lib/silcclient/client_prvmsg.c.
1884 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Fixed the private message sending in the Irssi SILC client,
1887 added local command KEY to the Irssi SILC client.
1889 Added key management and key agreement message formats to the
1890 irssi/src/fe-common/silc/module-formats.[ch].
1892 Added USERS (alias WHO) printing, server/router operator
1893 indication and LIST command printing to the module formats.
1895 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Fixed channel joining notify handling, cumode notify handling
1898 from Irssi SILC client.
1900 * Added SILC specific module-formats to the Irssi SILC client so
1901 that SILC specific message hilighting, colors etc is possible.
1902 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1904 Added channel mode, channel user mode, actions, notices,
1905 whois and whowas printing to the the module-formats.c.
1907 * Fixed a bug in channel deletion in the server. The channel
1908 is not left to the cache even if the channel founder auth mode
1909 is set when there are no users anymore on the channel. Affected
1910 file silcd/server.c.
1912 * The silc_net_localhost now resolves the entire hostname including
1913 the domain name. Affected file lib/silcutil/silcnet.c.
1915 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * Changed the ask_passphrase client operation to be ascynchronous.
1918 It has now a completion callback and a context that the
1919 application must call after it has got the passphrase from
1920 the user. Affected files lib/silcclient/silcapi.h,
1921 lib/silcclient/protocol.c, lib/silcclient/command.c and
1924 Added SilcAskPassphrase callback that the application calls
1925 to deliver the passphrase to the library.
1927 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1928 The public key verification and especially a certificate
1929 verification is asynchronous procedure.
1931 Added new SILC_SKE_STATUS_PENDING status to indicate the
1932 request is pending and a callback will be called to finalize
1935 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1936 indicate that remote end did not send its public key (or
1937 certificate), even though we require it. Added check for this
1938 condition in the SKE. This was a security bug, now fixed.
1940 Defined new SilcSKEVerifyCbCompletion callback that is called
1941 when the verification process is completed.
1943 The affected files lib/silcske/silcske_status.h and
1944 lib/silcske/silcske.[ch].
1946 * Changed the verify_public_key client operation to be async
1947 as well. Defined SilcVerifyPublicKey callback that is used to
1948 indicate the success of the public key verification process.
1950 Changed the server and client to use the new async client
1953 * Changed the Irssi SILC client's internal scheduler to be called
1954 twice as many times as it used to be. As a result the client
1955 should be a bit faster now. Affected file is
1956 irssi/src/silc/core/silc-core.c.
1958 * Added support to Irssi SILC client of asynchronous public key
1959 verification and passphrase inquiry. Affected file is
1960 irssi/src/silc/core/silc-core.c.
1962 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1964 * Do not say "You have left channel %s" in client library.
1965 Moved it to the application. Affected files are
1966 lib/silcclient/command.c and silc/client_ops.c.
1968 * Fixed silc_client_get_clients. Command context was not
1969 duplicated and was freed memory in the callback. Affected
1970 file lib/silcclient/idlist.c.
1972 * Do not say "you are now talking..." on JOIN command in the
1973 client library. The appliation must handle it.
1975 * Do not say ".. changed topic to" in command reply in the
1976 client libary. The application must handle it.
1978 * Fixed TOPIC command sending in the client library.
1980 * Fixed a memory leak in silc_client_command_free in the file
1981 lib/silcclient/command.c.
1983 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Imported a modified version of Irssi client to the source tree.
1986 The Irssi will be used to create a new client called
1987 Irssi SILC. Imported to irssi/.
1989 Added silc_core_init_finish function to the Irssi. Affected
1990 file irssi/configure.in.
1992 A lot changes in the Makefile.ams around the irssi tree.
1994 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Do not rehash if the new size is same as the old size of the
1997 hash table, in the silc_hash_table_rehash*. The affected file
1998 lib/silcutil/silchashtable.c.
2000 * Replaced hash_table_del_by_context calls from the server
2001 (when channel->user_list and client->channels) to the
2002 hash_table_del as it is sufficient and faster.
2004 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Added silc_hash_table_list, silc_hash_table_get and the
2007 SilcHashTableList structure to provide an alternative way to
2008 traverse the hash table. The affected files are
2009 lib/silcutil/silchashtable.[ch].
2011 * Changed the server's idlist routines to use the hash table
2012 routines to optimize the code.
2014 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Replaced the client entry's `channel' list and channel entry's
2017 `user_list' list to hash tables for optimized lookup. Changed
2018 the code to use the hash table interface around the code.
2019 Affected file lib/silcd/idlist.[ch].
2021 * Added `auto_rehash' boolean argument to the function
2022 silc_hash_table_alloc to indicate whether the hash table should
2023 auto-rehash when it thinks is appropriate time. It will
2024 increase the hash table size if the there is twice as much
2025 entries in the table than the size of the table, and will
2026 decrease the size if there are twice as less entries than
2027 the size of the table.
2029 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2033 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * silc_idcache_purge_by_context deletes the entry now by context
2036 as it is supposed to do. Affected file lib/silccore/idcache.c.
2038 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2039 client is not anymore valid (WHOWAS givens the info) and not
2040 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2042 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Removed the `data' and `data_len' arguments from the ID Cache
2045 interfaces and added `name' argument. ID Cache does not handle
2046 anymore the binary data only a names associated with given ID.
2048 * When hashing a Client ID with silc_hash_id the entire ID is
2049 not hashed anymore, instead only the hash of the Client ID is
2050 hashed. This way we can access the Client ID from the cache
2051 with Client ID but with the hash of the ID (which is a hash of
2052 the nickname) as well without any difference in performance.
2054 Added also silc_idcache_find_by_id_one_ext to do one on one
2055 searching when we have the actual ID. Added also function
2056 silc_hash_client_id_compare. The affected files are
2057 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2059 * When hashing the name associated with a ID it is always done
2060 in lowercase. This way we can access the cache without worrying
2061 about case-sensitivity, even though, for example nicknames are
2064 * Fixed a bug in server with channel message sending. It put
2065 wrong ID type as destination ID. The affected file
2066 silcd/packet_send.c.
2068 * silc_idcache_del_by_context now deletes from all hash tables
2069 by context. Affected file lib/silccore/idcache.c.
2071 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2073 * Changed the client library to use the new ID Cache interface.
2074 Changes around the source tree.
2076 * Added silc_hash_table_rehash_ext to rehash with specific
2077 hash function. Affected file lib/silcutil/silchashtable.[ch].
2079 * Added silc_hash_string_compare to compare two strings in the
2080 hash table. Affected file lib/silcutil/silcutil.[ch].
2082 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added new function silc_idcache_del_by_context into the
2085 lib/silccore/idcache.[ch].
2087 * Changed the server's ID list routines to use the new ID Cache
2088 interface. Changes around the source tree.
2090 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Added silc_hash_table_del[_by_context]_ext functions in to the
2093 lib/silcutil/silchashtable.[ch].
2095 Removed silc_hash_table_find_all* routines and added new
2096 silc_hash_table_find_foreach to replace them.
2098 Added silc_hash_table_replace_ext function as extended
2099 replacing function. Separated the simple hash table interface
2100 from the extended hash table interface in the file
2101 lib/silcutil/silchashtable.h.
2103 * Fixed minor bugs and changed it to use some of the new
2104 hash table functions in lib/silccore/idcache.c
2106 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Added new function silc_hash_table_find_all to return all keys
2109 in the hash table by the specified key. As the hash table is
2110 collision resistant it also makes it possible to have several
2111 duplicate keys in the hash table. This function may be used to
2112 find all of the keys from the hash.
2114 Added user_context arguments to the SilcHashFunction,
2115 SilcHashCompare and SilcHashDestructor to deliver user specified
2118 Added new fuctions silc_hash_table_find[_all]_ext to do
2119 extended lookup with specified hash and compare functions and
2120 specified user contexts.
2122 Added new function silc_hash_table_add_ext to add the key
2123 with specified hash function and user context.
2125 Added new function silc_hash_table_foreach to traverse all
2126 entrys in the hash table. Added SilcHashForeach callback
2129 Added new function silc_hash_table_del_by_context to delete
2130 the entry only if the context associated with the key matches.
2132 Affected files are lib/silcutil/silchashtable.[ch].
2134 * Removed silc_hash_[server/client/channel]_id and added just
2135 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2136 silc_hash_id_compare to compare two ID's using as the hash table
2137 comparison function. Added also silc_hash_data to hash
2138 binary data and silc_hash_data_compare to compare it.
2140 * Removed silc_idlist_find_client_by_hash as it is not needed
2141 anymore. Affected file silcd/idlist.[ch].
2143 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2144 to use internally the SilcHashTable. The new ID Cache is a lot
2145 faster than the old one. Some of the ID Cache interface was also
2146 rewritten and obsolete and stupid functions were removed.
2148 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Added entry_count field to the SilcHashTable to keep the number
2151 of the entries in the table. Implemented the function
2152 silc_hash_table_rehash. Added new function
2153 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2155 Fixed a minor bug in silc_hash_table_free.
2157 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2158 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2159 into the lib/silcutil/silcutil.[ch].
2161 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Implemented a collision resistant hash table into the
2164 lib/silcutil/silchashtable[ch]. See the header and the source
2165 for the SilcHashTable API.
2167 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Merged dotconf version 1.0.2 into lib/dotconf.
2171 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2173 * Do not compile anything in lib/silcsim/* if the SIM support
2174 is not enabled. The tree should now compile without problems
2177 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Compiled the SILC under cygwin. Compiled and tested briefly
2180 without problems. More tests needed. The SIMs didn't compile
2183 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2185 * Fixed possible crash in silc_get_username in the
2186 lib/silcutil/silcutil.c.
2188 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Fixed a va_arg in silc/client_ops.c.
2192 * Oops, RC5 routines were named AES and caused some problems
2193 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2195 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Added new SilcIDIP structure into the lib/silccore/id.h and
2198 replaced the old `ip' fields from all SILC ID's to that type.
2199 This is a step towards IPv6 support.
2201 The silc_id_get_len takes now the ID as an extra argument.
2202 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2203 both IPv4 and IPv6 based ID's.
2205 The affected files are lib/silccore/id.[ch] and other files
2206 around the tree using these routines.
2208 * Removed the ID length arguments in server from various
2209 silc_server_send_notify_* routines -> they are not needed
2212 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Fixed memory leak in silc_encode_pem_file in the file
2215 lib/silcutil/silcutil.c.
2217 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Check minor version as well in the SKE. Affected files are
2220 silcd/protocol.c and lib/silcclient/protocol.c.
2222 * Added --identifier option to the server so that an identifier
2223 can be when creating the public key for the server. Affected
2224 file is silcd/silcd.c.
2226 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2227 lib/silccrypt/silcpkcs.c.
2229 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Register default ciphers and stuff when using -C option with
2232 the server. Affected file sildc/silcd.c.
2234 * Put back the servers public key filename format, it is better
2235 than the new one. For now, the client keys are saved with the
2236 new filename format. The affected file silc/client_ops.c.
2238 * Implemented the Cipher API for the rest of the ciphers that
2239 did not implement it or implemented it the wrong way.
2241 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Register default ciphers and stuff when using the -S option
2244 in the client. Affected file silc/silc.c. Same also when
2245 creating new key pair with -C option.
2247 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Fixed the silc_verify_public_key client operation function to
2250 save the public keys differently. The fingerprint is now
2251 used as filename and not the hostname. This way also the
2252 client keys are saved uniquely and not with hostnames. The
2253 affected file is silc/client_ops.c.
2255 * Trimmed the silc_hash_fingerprint function to remove extra
2256 whitespaces from the end of the fingerprint. The affected
2257 file is lib/silccrypt/silchash.c.
2261 * Added silc_cipher_register_default function to register all
2262 default ciphers. It can be used when configuration files
2263 does not exist and the application does not want any specific
2264 ciphers in any specific order.
2266 The SilcDList is now used as silc_cipher_list dynamically
2267 allocated cipher list. Removed the static list all together
2268 and now all ciphers must be allocated to the dynamic list.
2269 The silc_cipher_alloc routine was changed to check only the
2272 All silc_cipher_* routines that used to return int returns
2275 The affected files lib/silccrypt/silccrypt.[ch].
2277 * The same thing was done to silc_hash_* as for silc_cipher_*
2278 routines. Affected files lib/silccrypt/silchash.[ch].
2280 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2281 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2282 Added also silc_pkcs_[un]register[_default] functions.
2283 Removed the data_context from the PKCS API.
2285 * Added silc_hmac_register_default function to register default
2286 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2287 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2288 to unregister all hmacs at once.
2290 * Register the default ciphers, hash functions, PKCSs and HMACs
2291 if client's configuration file does not exist. The affected
2294 * The client did not load the hash functions from the SIM
2295 modules at all. Added support for this. Affected file is
2296 silc/clientconfig.c.
2298 * When decoding public key with silc_pkcs_public_key_decode, check
2299 the supported algorithm only if PKCS are registered. Affected
2300 file lib/silccrypt/silcpkcs.c. The same was done with the
2301 silc_pkcs_private_key_decode.
2303 * Fixed the SILC List routines to keep the list always in order.
2304 It used to change the list's order when traversing the list but
2305 not it preserves the order. Affected file lib/trq/silclist.h.
2307 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Added the client library to use the SilcSocketConnection's
2310 reference counter (by silc_socket_dup) to prevent the bug that
2311 the socket object may be freed underneath async operation.
2313 * The name resolv library checking fixes in the configure.in.pre.
2316 * Created new version of the protocol drafts for future
2317 development. The -03 drafts are the ones that will be changed
2318 in the trunk now and the -02 will remain as they are.
2320 * Send list of CUMODE notifys to the router when announcing
2321 the channel users to the router. Affected file silcd/server.c.
2322 If the router receiving channel founder CUMODE for a channel
2323 that already has channel founder it will send CUMODE notify
2324 to the sender to remove the channel founder rights from the
2325 announced client. Affected file silcd/packet_receive.c.
2327 * The CUMODE notify may now use Server ID as well as the entity
2328 who changes the mode. Updated protocool specs.
2330 * Updated INSTALL and README files.
2332 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * New web pages in the http://silc.pspt.fi. The pages was
2339 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Implemented the [DenyConnectin] config section in the server.
2342 Added silc_server_config_denied_conn to check whether incoming
2343 connection is denied. Affected file silcd/serverconfig.[ch].
2345 * Do not check the ports when checking the incoming configuration
2346 data if the port is 0, meaning any. Affected file is
2347 silcd/serverconfig.c.
2349 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Fixed buffer overflow in silc_string_compare in the file
2352 lib/silcutil/silcutil.c.
2354 * Fixed double free in silc_server_command_leave in the file
2357 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Fixed the version checking in the server. Affected file is
2362 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Fixed the configuration data fetching when accepting new
2365 connections in the server. Affected file silcd/server.c.
2367 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Added `sender_entry' argument to the function
2370 silc_server_packet_relay_to_channel so that we can check
2371 whether some destination actually belongs to the same route
2372 the sender belongs (ie, we must not resend the packet to the
2373 sender). Affected file silcd/packet_send.[ch].
2375 * Added `servername' field to the SilcClientEntry in the server
2376 to hold the name of the server where client is from. Affected
2377 file is silcd/idlist.h.
2379 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Moved the channel message encrypting in the router betwen
2382 router connections from silc_server_channel_message to the
2383 silc_server_packet_relay_to_channel since we want to check
2384 whether we have anybody channel before encrypting anything.
2385 Affected files silcd/packet_[receive/send].c.
2387 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Fixed the [AdminConnection] server config section to support
2390 multiple entries. Affected file silcd/serverconfig.c.
2392 * Added support into the server to check the validity of the
2393 incoming connection before executing any KE or authentication
2396 * The connection configuration is now saved to the KE and
2397 connection auth protocol contexts and not fetched anymore in
2398 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2400 * The local hosts listenning address and port is also resolved
2401 now when starting the server. We want to have the socket object
2402 to include the real address and port for the listener. Added
2403 new function silc_net_check_local_by_sock into the files
2404 lib/silcutil/silcnet.[ch].
2406 * Fixed a broadcast bug in server -> do not broadcast if we
2409 * Fixed a routing bug. Do not route broadcast packets ever.
2410 Broadcast packets must be processed always and not routed since
2411 they may be destined to some other host than yourself and thus
2412 would get routed without no good reason. Affected file is
2415 * Added function silc_server_config_is_primary_route to check
2416 whether primary router connection has been configured (a router
2417 configuration that we are initiating). If there is not, we
2418 will assume that there is only two routers in the SILC network
2419 and we will use the incoming router connection as our primary
2420 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2422 * Changed the order of the broadcasting. Broadcast _after_ the
2423 packet has been processed not before. Affected file is
2426 * Fixed a [ClientConnection] parsing bug. The port was never
2427 parsed correctly thus resulting to port 0. Affected file
2428 silcd/serverconfig.c.
2430 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2431 argument and did not set the broadcast packet flag. Affected
2432 file silcd/packet_send.c. Fixed same bug in the function
2433 silc_server_send_notify as well.
2435 * If we receive NEW_ID packet for our own ID in the server, ignore
2438 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Removed the nickname from the Private Message Payload.
2443 Updated the code and the protocol specs.
2445 * Updated protocol specs for submitting to the IETF.
2447 * Tweaked the Random Number Generator a bit. Affected file
2448 lib/silccrypt/silcrng.c. Exported a new function
2449 silc_rng_[global]_add_noise which can be used to add more
2452 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Do not parse packets with different timeout when protocol
2455 is active -> may cause problem with rekey. Affected file
2458 * When server receives signoff notify it must not create
2459 new channel key if the client is on any channels since the
2460 sender of the signoff notify will create it.
2462 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Added printing of error messages during SKE protocol from the
2465 failure packet sent by server during SKE. Affected file
2468 * Removed the client's failure_callback handling with timeout
2469 and handle it immediately when received.
2471 * The SKE library returned wrong type in SUCCESS and FAILURE
2472 packets. They must be 32 bit MSB not 16 bit MSB.
2474 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Ok, rewrote the logic of the re-key and now it seems to work.
2477 I tested it on high traffic with frequent re-keys without
2478 problems. Added hmac_receive (and renamed hmac to hmac_send)
2479 in SilcClientConnection in lib/silcclient/client.h and
2480 in SilcIDListData in silcd/idlist.h. Also, removed the
2481 SilcPacketParserContext's cipher and hmac fields as they are
2482 not needed anymore and actually caused some problems when
2483 the ciphers and hmac's changed underneath the packet parser.
2485 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * If re-key protocol is active then process the incoming packets
2488 synchronously since we must assure that icoming packets encrypted
2489 with the old key is processed before the new keys is set to
2490 use. This is true other packets than for REKEY packets.
2491 Affected file silcd/server.c. The same was done to client library
2492 as well, affected file lib/silcclient/client.c.
2494 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Fixed bug in client and server to accept the force send if
2497 the packet is send from silc_[server/client]_packet_process
2498 function. Otherwise the packets are never delivered, oops.
2500 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2502 * Disable force sending of packets when REKEY protocol is active.
2503 We must assure that no packet is sent directly when rekey is
2504 performed. All packets must be sent through packet queue.
2505 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2506 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2507 function is silc_[server/client]_packet_send_real to check
2510 * Replaced the SIM paths from example config files to
2511 /usr/local/modules. Also, make install creates now
2512 /usr/local/silc/logs directory to hold all the SILC server
2515 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Made the configure.in.pre work on Solaris. Patch by salo.

2520 CBC mode macros into lib/silccrypt/ciphers_def.h.
2522 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Fixed the make install.
2526 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * When MAC computation fails the silc_packet_decrypt returned 0
2529 even though it was supposed to return -1. Fixed this. The
2530 affected file is lib/silccore/silcpacket.c.
2532 * Do not replace the config files in /etc/silc (in make install)
2533 if they already exist. Affected file ./Makefile.am.
2535 * Do not send re-key packets immediately but through packet queue.
2536 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2538 * Changed silc_net_check_host_by_sock to return FALSE if the
2539 IP/DNS could not be resolved. Though, it returns the IP address
2540 now even if it could not resolve it (but returns also FALSE).
2541 Affected file lib/silcutil/silcnet.[ch].
2543 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Added silc_pkcs_decode_identifier to decode the public key's
2546 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2547 Added also silc_pkcs_free_identifier. Added also new context
2548 SilcPublicKeyIdentifier.
2550 * Added -S option to the silc client. It is used to dump the
2551 contents of the specified public key file.
2553 * Changed the PKCS api to return the public key length when
2554 setting the public key.
2556 * Fixed a fatal bug in the public and private key file loading.
2557 Affected file lib/silccrypt/silcpkcs.c.
2559 * Execute the packet parsing for client with zero (0) timeout
2560 if the protocol is active. Affected file silcd/server.c.
2562 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Made the key generation options to the silcd program. Added
2565 -C option, equivalent to client's option.
2567 * Added new [ServerKeys] config section to the server. It
2568 configures the server's public and private key.
2570 * Defined generic Public Key Payload into the protocol
2571 specification to send specific type of public keys and
2574 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2575 public key or certificate.
2577 * Implemented the GETKEY command to the server and to the
2578 client library and on user interface.
2580 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Made preliminary `make install' work.

2611 SilcClientConnection structure; not needed. Affected file is
2612 lib/silcclient/client.h.
2616 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Do not ask whether user wants to use the negotiated private key
2619 for private messages, just use it. Affected file is
2620 silc/local_command.c.
2622 * Added `send_enc_key' and `enc_key_len' fields to the
2623 SilcIDListData structure since they are needed in the re-key

2638 the PFS is to be performed in the re-key. Affected file is
2641 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2644 int64 of at least the xintXX size. If void * is less that 4
2645 bytes uint32 * will be used. Defined bool as boolean.
2647 * Changed _ALL_ unsigned long and unsigned int to uint32,
2648 unsgined short to uint16 in the source tree.
2650 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2651 not handle clients that has entry->data.registered == FALSE.
2652 They are not in the network anymore. Affected file is
2655 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Implemented the sending of the SERVER_SIGNOFF notify in the
2658 server. Affected file is silcd/server.c.
2660 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

2670 application. Affected file silc/client_ops.c.
2672 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2673 if the deleting was successful. Affected file silcd/idlist.[ch].
2675 * Added support for public key authentication in the connection
2676 authentication protocol in the client library. Affected file
2677 lib/silcclient/protocol.c.
2679 * Changed the server's silc_idlist_get_clients_by_* interface
2680 to support already allocated array so that new entries may be
2681 added to pre-allocated array. Affected file silcd/idlist.[ch].
2682 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2683 and command replies.
2685 * All command reply functions in the server now calls the
2686 pending command callback even if error occured. This way the
2687 error will be delivered to the client as well. Affected files
2688 silcd/command.c and silcd/command_reply.c.
2690 * Fixed INFO command to return local server's info if no server
2691 was provided. Affected file lib/silcclient/command.c.
2693 * Removed RESTART command for good. Updated the code and the
2696 * Rewrote parts of the task system. It is a bit simpler now.
2697 Removed unsued task priorities. The affected files are
2698 lib/silcutil/silctask.[ch].
2700 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Moved the USERS printing from the library to the application.
2703 Affected files lib/silcclient/command.c and silc/client_ops.c.
2705 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Added channel key re-key support. The re-key is perfomed
2710 only by the router and is done once in an hour. Added `rekey'
2711 field to the SilcChannelEntry in the server. Affected files
2712 silcd/server.c and silcd/idlist.h.
2714 * Added silc_task_unregister_by_context into the file
2715 lib/silcutil/silctask.[ch].
2717 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Added SILC_UMODE_GONE mode to indicate when the client is not
2720 present in the SILC network. Added also support to the local
2721 command AWAY that will set this mode. Added support of showing
2722 "xxx is gone" in WHOIS command. The USERS command shows the
2723 gone status as well.
2725 * Fixed setting server and router operator privileges in the
2726 server's UMODE command. Affected file silcd/command.c.
2728 * Merged the SKE KE1 and KE2 payloads into one payload. The
2729 new KE payload is equivalent to the old KE2 payload.
2731 Cleaned up the SKE Start Payload parsing. It now uses the
2732 simple buffer unformatting to do the parsing. A lot faster
2735 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2736 to the SKE that is used to indicate whether both of the SKE
2737 parties should perform authentication. By default only the
2738 responder performs authentication. By setting this flag also
2739 the initiator must do authentication. By default it is unset
2740 since in normal SKE case, client to server connection, only
2741 the responder should do authentication. When doing SKE between
2742 two clients both should perform authentication. Updated the
2743 code and the protocol specs.
2745 * A little fix to IDENTIFY command in the server. Search the
2746 client first by hash not nickname. Affected file is
2749 * Fixed the silc_client_close_connection to support closing
2750 the client to client connections wihtout deleting too much
2751 data. Affected file lib/silcclient/client.c.
2753 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2754 are received if protocol used to be active but is not anymore
2755 the application would crash due to NULL pointer dereference.
2756 Affected files silcd/server.c and lib/silcclient/client.c.
2758 * Added `hash' field to the SilcClientConnection to include
2759 the hash function negotiated in the SKE protocol.
2761 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2762 to set the channel founder authentication data. A client can
2763 claim the founder rights later by providing the authentication
2764 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2765 This way the channel founder can regain the channel founder
2766 privileges even it is left the channel. This works only on
2767 local server and the client must be connected to the same
2768 server to be able to regain the founder rights. Updated the
2769 protocol specs accordingly.
2771 Added support to the CMODE command in the client to set the
2772 founder auth data. Read the README to see how to set it.
2774 Added support to the CUMODE command to claim the founder
2775 rights. Read the README to see how to do it.
2777 Added support for the founder authentication to the Channel
2778 Entry in the server. Affected file silcd/idlist.h.
2780 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2781 server's CMODE command. Affected file silcd/command.c.
2783 * Added the following new functions into lib/silccore/silcauth.[ch]:
2784 silc_auth_get_method and silc_auth_get_data.
2786 * The server now saves the remote hosts public key to the
2787 SilcIDListData pointer. Affected file silcd/protocol.c.
2789 * The normal server now does not remove the channel entry from
2790 the cache if the founder authentication data is set. It used
2791 to remove it if the founder was the last one on the channel on
2792 the server and left the channel. The auth data is saved and
2793 if the channel is re-joined later the old entry is used with
2794 the old auth data. Affected files silcd/command_reply.c and
2797 * Removed the `pkcs' field from the SilcIDListData structure
2798 in the server; it is not used. Affected file silcd/idlist.h.
2800 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2802 * Fixed packet processing on slow links. Partial packets were
2803 never re-processed because the incoming data buffer was cleared
2804 by the application. Application must not directly clear the
2805 sock->inbuf, the packet processing routines handle it. Fixed
2806 this in client library and in server.
2808 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Fixed the WHOIS and IDENTIFY send reply function to really
2811 check whether to send list or just one entry. Affected file
2814 * Cleaned up the LEAVE command's channel key distribution. The
2815 affected file silcd/command.c.
2817 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2818 can enforce the channel mode as well. In that case the ID
2819 includes the ID of the server. The code now enforces the
2820 mode change if the router have different mode than the server.
2822 * The notify client operation with CMODE_CHANGE notify can now
2823 return NULL client_entry pointer if the CMODE was not changed
2824 by client. Application must check for this.
2826 * Added <Server ID> argument to INFO command to support server
2827 info fetching by Server ID.
2829 * Added silc_server_announce_get_channel_users to get assembled
2830 packets of channel users of the specified channel. Affected
2831 file silcd/server.[ch].
2833 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2834 was freed underneath the ID Cache.
2836 * Re-announce clients when the server received CHANNEL_CHANGE
2837 notify from the router. Affected file silcd/packet_send.c.
2839 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2842 crashed since it did not handle the fact that there is no cipher
2843 called "3" and didn't check the error condition. Now fixed.
2845 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2846 flag. It can be used to send message requests.
2848 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Implemented the RESTART command in the client.
2852 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2853 notice type messages. Added notice printing to the user
2856 * The channel keys are not re-generated if the channel's mode
2857 is PRIVKEY, ie private key on the channel exists. Affected
2858 files silcd/server.c and silcd/command.c.
2860 * Fixed a little bug in channel message delivery when channel
2861 private keys are set in the server. Affected file is
2862 silcd/packet_send.c.
2864 * Changed the setting on channel->on_channel = TRUE from the
2865 silc_client_save_channel_key to the JOIN command reply. The
2866 key payload is not received if the private channel key is set.
2867 Affected file lib/silcclient/command_reply.c and the
2868 lib/silcclient/client_channel.c.
2870 * When the CMODE_CHANGE notify is sent and the channel private
2871 key mode is removed the channel key must be re-generated in
2872 other cells as well. Added this support for the router in the
2873 silcd/packet_receive.c.
2875 * Added new local command NOTICE to send notice message on
2876 channel. Affected file silc/local_command.[ch].
2878 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Added new local command ME to the client. It is used to send
2881 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2882 some action. Affected file silc/local_command.[ch].
2884 * Changed channel_message and private_message client operations
2885 to deliver the message flags to the application. Added also
2886 the `flags' arguments to the silc_client_send_channel_message
2887 and silc_client_send_private_message functions. Affected file
2890 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Redefined the Private Message Payload to support private message
2893 keys and to support the new private message flags. Updated
2894 the protocol specs. Flags makes it possible to have for example
2895 CTCP style messages.
2897 * Added new type SilcPrivateMessagePayload and defined an API
2898 for it in the lib/silcclient/silcprivate.[ch].
2900 * Tested private message private keys successfully. Tested the
2901 private message key set, unset and list commands with the new
2904 * Redefined the Channel Message Payload to include the channel
2905 message flags (equal with private message flags) to support
2906 for example CTCP style messages.
2908 * Defined some of the message (for channel and private message)
2909 flags. Updated the protocol specs and added the flags to the
2910 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2912 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Added SilcKeyAgreementStatus type to the key agreement routines
2915 to indicate the current status and error if one occured.
2916 The status types are defined in the lib/silcclient/silcapi.h.
2918 * Added new local command KEY that is used to set and unset private
2919 keys for channels, set and unset private keys for private messages
2920 with remote clients and to send key agreement requests and
2921 negotiate the key agreement protocol with remote client. The
2922 key agreement is supported only to negotiate private message keys,
2923 it currently cannot be used to negotiate private keys for channels,
2924 as it is not convenient for that purpose.
2926 * Fixed a minor pending callback setting bug in the function
2927 silc_client_get_client_by_id_resolve, now the function works.
2928 Affected file lib/silcclient/idlist.c.
2930 * Added function silc_net_get_local_port to get local bound
2931 port by socket. Added to lib/silcutil/silcnet.[ch].
2933 * Added `sockets' and `sockets_count' fields to the SilcClient
2934 object. They hold the sockets of the listenning sockets in
2935 the client. Listenning sockets may be for example the key
2936 agreement server. Affected file lib/silcclient/client.[ch].
2937 Added functions the silc_client_add_socket and the
2938 silc_client_del_socket. They are exported to the application
2941 * Added ~./silc/clientkeys to support other client's public keys.
2943 * Renamed verify_server_key client operation to verify_public_key
2944 and added one argument to indicate the type of the connection
2945 (server, client etc.).
2947 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Added silc_server_connection_auth_request to handle the
2950 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2951 silcd/packet_receive.[ch].
2953 * Added silc_server_send_connection_auth_request into the
2954 silcd/packet_send.c to send the connection auth request packet.
2956 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2959 * Fixed the public key authentication in responder side in the
2960 server. The `auth_data' pointer includes the SilcPublicKey
2961 not the path to the public key. Affected file silcd/protocol.c.
2963 * Implemented the public key authentication in the initiator side
2964 in the server. Affected file silcd/protocol.c.
2966 * Removed the [RedirectClient] config section from the server
2967 configuration. Is not needed and I don't want to implement it.
2969 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Cleaned up the CMODE command in the server. It now works
2972 correctly and supports all the modes defined in the protocol.
2973 Affected file is silcd/command.c.
2975 * Added `hmac_name' field to the SilcChannelEntry in the server
2976 to hold the default HMAC of the channel. It can be set when
2977 creating the channel (with JOIN command). Affected files
2980 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2981 type to indicate the change of the current cipher and hmac
2982 on the channel. Client can safely ignore the <cipher> argument
2983 (if it chooses to do so) since the CHANNEL_KEY packet will
2984 force the channel key change anyway. The <hmac> argument is
2985 important since the client is responsible of setting the new
2986 HMAC and the hmac key into use.
2988 * Fixed the CMODE command in the client library as well.
2990 * Tested CMODE command in router environment successfully.
2992 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Show the version of the remote client (or server) when connecting
2995 to the server. It is logged to the log file. Affected file
2996 is silcd/protocol.c.
2998 * Fixed the KILLED notify handling in the client library. The
2999 client must be removed from all channels when receiving the
3002 Also, do not remove the client entry when giving the KILL
3003 command but when the KILLED notify is received.
3005 * Removed silc_idlist_find_client_by_nickname from the server.
3006 Not needed anymore. Affected files silcd/idlist.[ch].
3008 * Implemented the CHANNEL_CHANGE notify type handling to the
3009 server. Affected file silcd/server.c.
3013 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Added silc_server_send_notify_invite to send the INVITE
3016 notify between routers.
3018 * Implemented the INVITE command correctly to the server.
3020 * Implemented the INVITE notify type handling in the server.
3022 * Implemented the INVITE command to the client library and on the
3025 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Added function silc_server_get_client_resolve to find the
3028 client entry by ID from all ID lists and then resolve it
3029 (using WHOIS) if it cannot be found. Affected file is
3032 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Implemented the BAN command to the client library.
3036 * The JOIN command in the server now checks the invite list
3039 * Changed the silc_command_reply_payload_encode_va and the
3040 silc_command_payload_encode_va to support that if argument is
3041 NULL it ignores and checks the next argument. Affected file
3042 lib/silccore/silccommand.c.
3044 * Added silc_server_send_notify_ban to send the BAN notify
3045 type between routers.
3047 * Chaned the silc_notify_payload_encode to support that if
3048 argument is NULL it ignores and checks the next argument.
3049 Affected file lib/silccore/silcnotify.c.
3051 * Tested ban lists in router environment successfully.
3053 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Implemented BAN command to the server, in silcd/command.[ch].
3057 * Removed the BAN and INVITE_LIST modes from the CMODE command
3060 * Added function silc_string_match to regex match two strings.
3061 Affected files lib/silcutil/silcutil.[ch].
3063 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Redefined parts of the SilcChannelEntry in the server to support
3066 the new ban and invite lists.
3068 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Redefined the INVITE command. The same command can be used to
3071 invite individuals to the channel but also to manage the invite
3072 list of the channel (to add to and remove from the invite list).
3073 Updated the protocol specs.
3075 * Added new command SILC_COMMAND_BAN that can be used to manage
3076 the ban list of the channel. Updated the protocol specs.
3078 * Removed the channel modes: the SILC_CMODE_BAN and the
3079 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3080 in the CMODE command. The equivalent features are now available
3081 using INVITE and BAN commands. Updated the protocol specs.
3083 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3084 in the network about change in the current ban list. The notify
3085 type is not used by the client.
3087 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3088 support the invite lists.
3090 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Added new function silc_string_regexify that converts string
3093 including wildcard characters into regex string that can
3094 be used by the GNU regex library. Added into the file
3095 lib/silcutil/silcutil.[ch].
3097 Added silc_string_regex_combine to combine to regex strings
3098 into one so that they can be used as one regex string by
3099 the GNU regex library. Added into the file
3100 lib/silcutil/silcutil.[ch].
3102 Added silc_string_regex_match to match two strings. It returns
3103 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3105 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Imported GNU regex to the soruce tree into lib/contrib.
3108 Fixed some compiler warning from the regex.c.
3110 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Fixed MOTD command in the server to work in router environment.
3114 * Fixed the MOTD command in the client library to support
3115 the server argument in the command.
3117 * Added `nickname_len' argument to the silc_idlist_add_client
3118 in the server, as the `nickname' argument may be binary data
3121 * Added silc_idlist_get_channels to return all channels from
3124 * Implemented LIST command to the server. Affected file is
3127 * Implemented the LIST command to the client library and on the
3130 * Added [<user count>] argument to the LIST command reply.
3131 With private channels the user count is not shown.
3133 * Updated TODO and README.
3135 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * The client entry's data.registered must be TRUE even with
3138 global client entry on global client list. The data.registered
3139 is used to check whether the client is anymore in the network,
3140 for example with WHOWAS command so it must be valid.
3142 * Fixed the WHOWAS command in the server. It now actually works
3143 in router environment. Added function into silcd/command_reply.c
3144 silc_server_command_reply_whowas_save.
3146 * Added silc_idlist_purge function to the silcd/idlist.c
3147 to periodically purge the ID Cache.
3149 * Fixed INFO command in the server. It works now in router
3150 environment. Added <server name> argument to the INFO command
3151 reply. Updated the protocol specs.
3153 * Fixed minor bug in silc_idcache_purge to not purge if the
3154 expire value is zero.
3156 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3157 they were buggy because of the WHOWAS information.
3159 * Fixed local command MSG to handle the async resolving of
3160 the remote client properly. It used to fail the first MSG.
3161 Affected file silc/local_command.c.
3163 * Added `data_len' field to SilcIDCache context.
3165 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Update TODO. Todo in commands in the server.
3169 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3172 used by routers as broadcast packet to inform other routers
3173 about the changed user mode.
3175 Implemented the notify handling in the server. Affected file is
3176 silcd/packet_receive.c. Added the function
3177 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3179 * Added new generic Channel Payload and deprecated the New Channel
3180 Payload. The New Channel Payload is now the generic Channel
3183 * Added new argument `mode' to the silc_server_send_new_channel
3184 as it is required in the Channel Payload now.
3186 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3187 and created a new and real SilChannelPayload to represent the
3188 new generic Channel Payload. Implemented the encode/decode
3189 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3191 * Added silc_server_get_client_channel_list to return the list
3192 of channels the client has joined for WHOIS command reply.
3193 Affected file silcd/server.[ch].
3195 * Implemented the channel list sending in the WHOIS command reply
3196 in server and in the client.
3198 Implemented the channel list displaying on the user interface
3199 as well. Affected file silc/client_ops.c.
3201 * Added silc_channel_payload_parse_list to parse list of Channel
3202 Payloads. It returns SilcDList list of SilcChannelPayloads.
3203 Client for example can use this function to parse the list of
3204 channels it receives in the WHOIS command reply. The caller
3205 must free the list by calling silc_channel_payload_list_free.
3206 Affected files lib/silccore/silcchannel.[ch].
3208 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Added one new argument <user mode> to the WHOIS command reply
3211 to return the mode of the user in SILC. Updated the protocol
3214 Implemented it to the server and client.
3216 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Fixed the mode printing on the user interface on joining.
3219 Affected file silc/client_ops.c.
3221 * Implemented the UMODE command and user modes in general to the
3222 client library and to the user interface.
3224 * Implemented the UMODE command to the server.
3226 * The server now sends UNKNOWN_COMMAND error status if client sends
3227 unknown command. Affected file silcd/command.c.
3229 * All server commands now handle the command identifier the right
3230 way when sending the command reply to the client. The client can
3231 use to identify the command replies with the identifier.
3233 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added silc_server_get_client_route to resolve the route to
3236 the client indicated by the client ID. Affected file is
3239 * Added silc_server_relay_packet as general function to relay
3240 packet to arbitrary destination. This deprecates functions
3241 like _send_private_message_key, _relay_notify etc. Affected
3242 file is silcd/packet_send.[ch].
3244 Removed silc_server_send_key_agreement,
3245 silc_server_send_private_message_key and
3246 silc_server_packet_relay_notify functions from the file
3247 silcd/packet_send.[ch].
3251 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3252 server. Affected file silcd/packet_receive.[ch].
3254 * Implemented the KILL command to the client. Implemented the
3255 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3256 Affected files lib/silcclient/command[_reply].c and
3257 lib/silcclient/client_notify.c. Implemented the KILL notify
3258 printing in the user inteface.
3260 * Fixed a lot silc_parse_nick memory leaks from the client
3261 library in the file lib/silcclient/command.c.
3263 * Changed the silc_server_send_notify_on_channels's `sender'
3264 argument from SilcSocketConnection to SilcClientEntry to
3265 check the sender as entry and not as connection object and not
3266 to send to the client provided as argument. The affected file
3267 is silcd/packet_send.[ch].
3269 * The notify packets that are destined directly to the client used
3270 to not to be processed by the server. Now changed that and the
3271 server processes all notify packets. After relaying the packet
3272 to the client the notify packet is processed in the server.
3274 * The silc_server_free_client_data now checks whether there is
3275 pending outgoing traffic for the client and purges the data to
3276 the network before removing the client entry.
3278 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3281 an client is killed from the SILC Network. Updated the protocol
3284 Added new function silc_server_send_notify_killed to the
3285 silcd/packet_send.[ch].
3287 * Added function silc_server_packet_relay_notify to relay notify
3288 packets that are destined directly to a client. In this case
3289 the server does not process the notify packets but merely relays
3290 it to the client. Affected file silcd/packet_send.[ch].
3292 Added also silc_server_packet_process_relay_notify to check
3293 whereto relay the notify. Affected file is
3294 silcd/packet_receive.[ch].
3296 * Implemented the KILL command to the server.
3300 * Added the backup schema desgined last fall to the protocol
3301 specs for everyone to see. The specification is in the
3302 *-spec-xx.txt draft and the packet type definitions for the
3303 backup routers is in *-pp-xx.txt draft. Thusly, added also
3304 new packet type SILC_PACKET_CELL_ROUTERS.
3306 * A big security problem in the implementation discovered. The
3307 signoff of an client did not cause new channel key generation
3308 which it of course should've done. The channel keys must be
3309 always re-generated when client leaves (or signoffs) the channel.
3310 The silc_server_remove_from_channels funtion now handles
3311 the channel key re-generation.
3313 * Added `sender' argument to the silc_server_send_notify_on_channels
3314 to not to send the client provided as argument. Affected file
3315 silcd/packet_send.[ch].
3317 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Implemented OPER and SILCOPER commands into the server and
3322 * Added silc_auth_verify and silc_auth_verify_data to verify
3323 the authentication directly from the authentication payload.
3324 It supports verifying both passphrase and public key based
3325 authentication. Affected file lib/silccore/silcauth.[ch].
3327 * Added `hash' field to the SilcIDListData structure. It is the
3328 hash negotiated in the SKE protocol. Affected file is
3331 * Slight redesigning of the SilcAuthPayload handling routines.
3332 Do not send SilcPKCS but SilcPublicKey as argument.
3334 * Implemented the public key authentication support to the
3335 serverconfig. The public key is loaded from the provided path
3336 and saved as authentication data to void * pointer. Thus,
3337 changed the unsigned char *auth_data to void *auth_data;
3339 * Fixed SHUTDOWN command to send the reply before the server
3340 is shutdown. :) Affected file silcd/command.c.
3342 * Fixed fatal bug in CONNECT command. The hostname was invalid
3343 memory and server crashed. Affected file silcd/command.c.
3345 * Fixed fatal bug in CLOSE command. The server_entry became
3346 invalid but was referenced later in the command. Affected file
3349 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Fixed fatal bug in failure packet handling. Server ignored
3352 the failure and thus crashed when it came.
3356 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3359 that the command may be executed only once in (about) 2 seconds.
3360 The old SILC_CF_LAG flag is same but allows command bursts up
3361 to five before limiting.
3363 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3364 server code. Various commands now includes the CF_LAG_STRICT
3365 flag to disallow any kind of miss-use of the command.
3367 * Fixed the silc_buffer_unformat to not to allocate any data
3368 if the length of the data is zero. It used to allocate the
3369 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3371 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Changed the format of AdminConnection configuration section
3374 in the server. Added username of the admin to the format.
3375 Affected files silcd/serverconfig.[ch].
3377 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3378 to return admin configuration data by host, username and/or
3381 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Implemented WHOWAS command to the server. Added the functions:
3385 silc_server_command_whowas_parse,
3386 silc_server_command_whowas_send_reply,
3387 silc_server_command_whowas_from_client and
3388 silc_server_command_whowas_from_server
3390 * Added <Client ID> argument to the WHOWAS command reply. Updated
3391 the protocol specs accordingly.
3393 * Implemented WHOWAS command and command_reply to the client
3396 Implemented the WHOWAS printing on the user interface.
3398 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Added new argument to the WHOWAS command reply, the real name.
3401 It is an optional argument. Updated the protocol specs.
3403 * Added SilcIDCacheDestructor callback that is registered when
3404 the SilcIDCache is allocated. The callback is called when
3405 an cache entry in the ID Cache expires, or is purged from the
3406 cache. Added into lib/silccore/idcache.[ch].
3408 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3409 to destruct the client entries when the cache entry expires.
3410 Other ID Cache's in server and in the client library ignores
3413 * If the ID Cache entry's `expire' field is zero then the entry
3414 never expires. Added boolean `expire' argument to the
3415 silc_idcache_add function in the lib/silccore/idcache.[ch].
3416 If it is TRUE the default expiry value is used.
3418 * Added silc_server_free_client_data_timeout that is registered
3419 when client disconnects. By default for 5 minutes we preserve
3420 the client entry for history - for WHOWAS command.
3422 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Added support to the server to enforce that commands are not
3425 executed more than once in 2 seconds. If server receives
3426 commands from client more frequently, timeout is registered
3427 to process the commands. Affected file silcd/command.c.
3428 Added new function silc_server_command_process_timeout.
3430 * Changed NICK_NOTIFY handling in client library to check that
3431 if the client's nickname was changed, so there is no need to
3432 resolve anything from the server.
3434 * Removed error printing from the WHOIS and IDENTIFY commands.
3435 If error occurs then it is ignored silently in the client library.
3436 The application, however, may map the received error to
3437 human readable error string. The application currently maps
3438 the NO_SUCH_NICKNAME error to string.
3440 * Made the command status message public to the application. Moved
3441 them from lib/silcclient/command_reply.c to
3442 lib/silcclient/command_reply.h. The application can map the
3443 received command status to the string with the
3444 silc_client_command_status_message function.
3446 * Added check to the server to check that client's ID is same
3447 as the Source ID in the packet the client sent. They must
3450 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3452 * Added dist-bzip hook to the Makefile.am to make bzip2
3453 compressed distributions.
3455 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Server now enforces the maximum length for the nickname and
3458 the channel as protocol specification dictates. 128 bytes for
3459 nickname and 256 bytes for channel name.
3461 * Moved the WHOIS printing to the application. The client libary
3462 does not print out the WHOIS information anymore, the application
3463 must do it. Renamed silc_client_command_reply_whois_print to
3464 the silc_client_command_reply_whois_save.
3466 The client's idle time is also sent to the application now, and
3467 the idle is shown on screen.
3469 * Added silc_client_command_reply_identify_save to save the
3470 received IDENTIFY entries.
3472 * Do not check for channel private keys in message sending and
3473 reception if the channel does not have the PRIVKEY mode set.
3474 Affected file lib/silclient/client_channel.c.
3476 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3479 just surfaced after chaning the JOIN procedure.
3481 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Added silc_client_get_clients_by_list to get client entries
3484 from Client ID list, that is returned for example by JOIN
3485 and USERS command replies. The application should use this
3486 function for example when JOIN command reply is received to
3487 resolve the clients already on the channel (library does not
3488 do that anymore as USERS command reply is not used in the JOIN
3489 procedure anymore). Affected files lib/silcclient/silcapi.h and
3490 lib/silcclient/idlist.c.
3492 * JOIN command reply and USERS command reply returns now SilcBuffer
3493 pointers instead of unsigned char pointers when returning
3494 the client list and mode list.
3496 * Added <Client ID> argument to the JOIN command reply, mainly
3497 for the server to identify for which client the command was
3498 originally sent. Updated protocol specs accordingly.
3500 * Added SilcDlist private_key pointer to the SilcChannelEntry
3501 in the client to support the channel private keys. Affected
3502 file is lib/silcclient/idlist.h.
3504 * Added SilcChannelPrivateKey argument to the function
3505 silc_client_send_channel_message so that application can choose
3506 to use specific private ke if it wants to. If it is not provided,
3507 the normal channel key is used, unless private keys are set.
3508 In this case the first (key that was added first) is used
3509 as the encryption key.
3511 * Implemented the support for channel private key handling.
3512 Implemented the following functions:
3514 silc_client_add_channel_private_key,
3515 silc_client_del_channel_private_keys,
3516 silc_client_del_channel_private_key,
3517 silc_client_list_channel_private_keys and
3518 silc_client_free_channel_private_keys
3520 Affected file lib/silcclient/client_channel.c.
3522 * Added the support for the private keys in the channel message
3523 sending and encryption and in the message reception and
3524 decryption. Affected funtions are
3525 silc_client_send_channel_message and silc_client_channel_message.
3527 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Added SKE's key verify callback to the client library's
3530 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3532 * Removed the statement that server (or router) must send USERS
3533 command reply when joining to the channel so that the client
3534 knows who are on the channel. Instead, the client list and
3535 client's mode list is now sent in the JOIN command reply to the
3536 client who joined channel. This is better solution.
3538 * Added function silc_server_get_users_on_channel and function
3539 silc_server_save_users_on_channel to the silcd/server.[ch].
3541 * Removed function silc_server_command_send_users from the
3544 * Do not show topic on the client library anymore. The topic is
3545 sent in the command reply notify to the application and the
3546 application must show the topic now.
3548 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * Added client searching by nickname hash into the IDENTIFY and
3551 WHOIS commands in the server as they were clearly missing from
3552 them. Affected file is silcd/command.c.
3554 * Fixed a bug in private message receiving in the client library.
3555 The remote ID was freed and it wasn't supposed, now it is
3558 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Minor fix to the channel payload; allocate the data area, as it
3561 needs to be of specific length.
3563 * If the key agreement port is zero then the operating
3564 system will define the bound port. Affected files are
3565 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3567 * Added new function silc_channel_payload_decrypt into the file
3568 lib/silccore/silcchannel.[ch].
3570 * Moved the channel message etc, check from silc_packet_decrypt
3571 to applications. The library calls now a generic
3572 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3573 when the packet is either normal or special. This was done to
3574 allow more wide range of checking that was not allowed when
3575 the code was in library. Now applications can do virtually any
3576 checks to the packet and return to the library the decision how
3577 the packet should be processed. Affected files are
3578 lib/silccore/silcpacket.[ch].
3580 Added silc_server_packet_decrypt_check to the server and
3581 silc_client_packet_decrypt_check to the client library.
3583 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3584 to send with specified source and destination information.
3586 * Channel message delivery between routers was broken after the
3587 channel key distribution was fixed earlier. The channel key
3588 was used be to distributed to other routers as well which is not
3589 allowed by the protocol. Now this is fixed and channel keys
3590 really are cell specific and the channel message delivery between
3591 routers comply with the protocol specification.
3593 * Fixed various commands in server to check also the global list
3594 for the channel entry and not just the local list. The affected
3595 file silcd/command.c.
3597 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Added assert()s to buffer formatting and unformatting routines
3600 to assert (if --enable-debug) when error occurs. Affected
3601 file: lib/silcutil/silcbuffmt.c.
3603 * Changed to auto-reconnect to check whether the remote host is
3604 router and register the re-connect timeout if it is. It used
3605 to check that whether we are normal server, but router must do
3606 auto-reconnect with another router as well. Affected file
3609 * Removed the [<key len>] option from CMODE command as the cipher
3610 name decides the key length, nowadays. See the defined ciphers
3611 from the protocol specification.
3613 * Added [<hmac>] option to the CMODE command to define the HMAC
3614 for the channel. Added SILC_CMODE_HMAC channel mode.
3616 * Added [<hmac>] option for the JOIN command so that user can
3617 select which HMAC is used to compute the MACs of the channel
3620 * Added Hmac field to the Channel Message Payload. The integrity
3621 of plaintext channel messages are now protected by computing
3622 MAC of the message and attaching the MAC to the payload. The
3623 MAC is encrypted. Now, it is clear that this causes some
3624 overhead to the size of the packet but rationale for this is that
3625 now the receiver can verify whether the channel message decrypted
3626 correctly and also when private keys are set for the channel the
3627 receiver can decrypt the packet with several keys and check from
3628 the MAC which key decrypted the message correctly.
3630 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3631 lib/silccrypt/silccipher.[ch].
3633 * Added silc_hash_len to return the digest length into the
3634 lib/silcrypt/silchash.[ch].
3636 * Rewrote parts of Silc Channel Payload interface in the
3637 lib/silccore/silcchannel.[ch]. The encode function now also
3638 encrypts the packet and parse function decrypts it.
3640 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Fixed a minor formatting bug in the SKE's key material processing.
3643 It actually might have processed the keys wrong way resulting
3646 * Redefined the mandatory HMAC algorithms and added new algorithms.
3647 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3648 and hmac-md5 truncated to 96 bits. The mandatory is now
3649 hmac-sha1-96. Rest are optional (including the one that used
3650 to be mandatory). Rationale for this is that the truncated HMAC
3651 length is sufficient from security point of view and can actually
3652 make the attack against the HMAC harder. Also, the truncated
3653 HMAC causes less overhead to the packets. See the RFC2104 for
3656 * Added new [hmac] configuration section. The SKE used to use
3657 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3658 is of course wrong. The official names that must be proposed in
3659 the SKE are the ones defined in the protocol specification
3660 (hmac-sha1-96 for example). The user can configure any hmac
3661 using any hash function configured in the [hash] section. At
3662 least, the mandatory must be configured.
3664 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3666 * Added HMAC list to the SKE proposal list. It has now both
3667 hash algorithm list and HMAC list. This makes the protocol
3668 incompatible with previous versions. The SKE now seems to work
3669 the way it is supposed to work, for the first time actually.
3671 * Defined plain Hash algorithms to the protocol specification.
3674 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Implemented support for key agreement packets into the server.
3677 Added functions silc_server_key_agreement and
3678 silc_server_send_key_agreement. Other than these functions,
3679 server has nothing to do with this packet.
3681 * Added support for private message key packets into the server.
3682 Added functions silc_server_private_message_key and
3683 silc_server_send_private_message_key.
3687 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3688 called in the protocol's final callback instead in the END
3689 protocol state. This makes a little more sense and in the same
3690 time in client we can use the same protocol routines for normal
3691 key exchange and to key agreement packet handling as well.
3693 * Added to both client's and server's KE protocol context the
3694 SilcSKEKeyMaterial pointer to save the key material. We will
3695 bring the key material to the protocol's final callback by doing
3696 this. The final callback must free the key material.
3698 * Added SKE's packet_send callback into client's KE protocol
3699 context so that the caller can choose what packet sending function
3700 is used. This way we can use different packet sending when
3701 doing normal SKE when doing key agreement packet handling (in
3702 the key agreement packet handling we do not want to encrypt
3705 * Implemented the responder side of the key agreement routines
3706 in the client. The client can now bind to specified port and
3707 accept incoming key negotiation. The key material is passed
3708 to the application after the protocol is over.
3710 * Implemented the processing of incoming Key Agreement packet
3711 in the client. Added function silc_client_key_agreement to
3714 * Implemented the intiator side of the key agreement routines
3715 in the client. The client can now initiate key agreement with
3716 another remote client. The key material is passed to the
3717 application after the protocol is over.
3719 * Created client_keyagr.c to include all the key agreement
3722 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3723 SILC_TASK_CALLBACK except that it is not static.
3725 * Created client_notify.c and moved the Notify packet handling
3726 from the client.[ch] into that file.
3728 * Created client_prvmsg.c and moved all private message and
3729 private message key routines from the client.[ch] into that file.
3731 * Create client_channel.c and moved all channel message and
3732 channel private key routines from the client.[ch] into that file.
3734 * Changed silc_client_get_client_by_id_resolve to resolve with
3735 WHOIS command instead of IDENTIFY command, in the file
3736 lib/silclient/idlist.c.
3738 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Implemented the SKE's responder side to the Client library.
3742 * When FAILURE is received to the protocol do not trust it
3743 blindly. Register a timeout to wait whether the remote closes
3744 the connection as it should do it, only after that process the
3745 actual failure. This was changed to both client and server.
3747 * Added client_internal.h to include some of the structures
3748 there instead of client.h in lib/silcclient/.
3750 * Added function silc_task_unregister_by_callback to unregister
3751 timeouts by the callback function.
3753 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Some "Incomplete WHOIS info" errors has been appearing on the
3756 log files. Took away the entry->userinfo check from WHOIS
3757 reply sending. The entry->userinfo is now " " if client did not
3758 provide one. I thought this was fixed earlier but something
3759 is wrong still. Let's see if the error still appears.
3761 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed a minor bug in the login when the channel key is
3764 re-generated in the server. It used to generate the key in
3765 wrong order and thus caused problems in the channel traffic.
3767 * Fixed a minor bug in channel key distsribution after
3768 KICK command. The key was not sent to the router even though
3771 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Added silc_ske_process_key_material_data as generic routine
3774 to process any key material as the SILC protocol dictates. The
3775 function is used by the actual SKE library but can be used by
3776 applications as well. This relates to the private message keys
3777 and the channel private keys since they must be processed the
3778 same way the normal SILC session keys. The protocol dictates
3779 this. Affected files: lib/silcske/silcske.[ch].
3781 Added also silc_ske_free_key_material to free the
3782 SilcSKEKeyMaterial structure.
3784 * Defined silc_cipher_set_key function to set the key for
3785 cipher without using the object's method function. The affected
3786 files: lib/silccrypt/silccipher.[ch].
3788 * Implemented silc silc_client_add_private_message_key,
3789 silc_client_add_private_message_key_ske,
3790 silc_client_del_private_message_key,
3791 silc_client_list_private_message_keys and
3792 silc_client_free_private_message_keys functions in the
3795 Added functions silc_client_send_private_message_key to send
3796 the Private Message Key payload and silc_client_private_message_key
3797 to handle incoming Private Message Key payload.
3799 * Added Cipher field to the Private Message Key payload to set
3800 the cipher to be used. If ignored, the default cipher defined
3801 in the SILC protocol (aes-256-cbc) is used.
3803 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Removed lib/silcclient/ops.h file.
3807 Redefined parts of the SILC Client Library API. Created new
3808 file silcapi.h that deprecates the ops.h file and defines the
3809 published Client Library API. Defined also private message key
3810 API and channel private key API into the file.
3812 This is the file that the application must include from the
3813 SILC Client Library. Other files need not be included by
3814 the application anymore.
3816 * Added new key_agreement client operation callback and also
3817 defined the Key Agreement library API for the application.
3819 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3822 is used by clients to request key negotiation between another
3823 client in the SILC network. If the negotiation is started it
3824 is performed using the SKE protocol. The result of the
3825 negotiation, the secret key material, can be used for example
3826 as private message key.
3828 Implemented the Key Agreement payload into the files
3829 lib/silccore/silauth.[ch].
3831 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Redefined ciphers for the SILC protocol. Added some new ciphers
3834 and defined the key lengths for the algorithms. Changed the
3835 code accordingly. The default key length is now 256 bits.
3837 * Fixed SKE key distribution function silc_ske_process_key_material
3838 when the key length is more than 128 bits. The default key
3839 length in SILC is now 256 bits.
3841 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3842 to indicate unsupported algorithm.
3844 * Renamed rijndael.c to aes.c and all functions as well.
3846 * Fixed a long standing channel key setting bug in client library.
3847 Weird that it has never surfaced before.
3849 * Fixed bug in channel deletion. If the entire channel is removed
3850 then it must also delete the references of the channel entry
3851 from the client's channel list as the client's channel entry and
3852 the channel's client entry share same memory.
3854 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Implemented CONNECT and SHUTDOWN commands in the client.
3858 * Implemented CLOSE command to the client.
3860 * Added the function silc_idlist_find_server_by_name into the
3861 files silcd/idlist.[ch].
3863 Added the function silc_idlist_find_server_by_conn into the
3864 files silcd/idlist.[ch].
3866 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * DIE command was renamed to SHUTDOWN. Updated the both code
3871 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3872 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3874 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3877 * Added function silc_server_create_connection function to create
3878 connection to remote router. My server implementation actually
3879 does not allow router to connect to normal server (it expects
3880 that normal server always initiates the connection to the router)
3881 so the CONNECT command is only good for connecting to another
3884 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3887 or some other client was kicked from the channel.
3889 Implemented the handling of the notify type to both client
3892 Implemented silc_server_send_notify_kicked to send the KICKED
3893 notify. It is used to send it to the server's primary router.
3895 * Implemented the KICK command into server and client.
3897 * Added `query' argument to the silc_idlist_get_client function
3898 to indicate whether to query the client from server or not if
3901 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3902 to indicate that the client is not channel founder.
3906 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Removed the rng context from SilcPacketContext structure and
3909 changed that the packet routine uses the Global RNG API.
3911 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Added support for quit message that client can "leave" on the
3914 channel when it quits the SILC. It is ditributed inside the
3915 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3917 Added silc_server_free_client_data that will take the
3918 signoff message as argument.
3920 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3922 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Updated parts of the protocol specification to keep it up
3927 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3930 payloads in one packet.
3932 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3933 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3934 use now the new List flag.
3936 * Also deprecated the following packet types: REPLACE_ID,
3937 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3939 * Added list support for Notify packet in server.
3941 * Added silc_server_send_notify_channel_change to send the
3942 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3943 the silc_server_send_replace_id.
3945 * Added silc_server_send_notify_nick_change to send the
3946 NICK_CHANGE notify type. Deprecates the function
3947 silc_server_send_replace_id.
3949 * Added silc_server_send_notify_join to send the JOIN notify type.
3950 Deprecates the function silc_server_send_new_channel_user.
3952 * Added silc_server_send_notify_leave to send LEAVE notify type.
3953 Deprecates the function silc_server_send_remove_channel_user.
3955 * Added silc_server_send_notify_cmode and
3956 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3957 types. Deprecates the silc_server_send_set_mode function.
3959 * Added SERVER_SIGNOFF notify type to indicate that server has
3960 quit. This means that all clients on the channel from that
3961 server will drop. This can be also used when netsplit happens.
3963 Deprecated REMOVE_ID packet type since it is not needed anymore
3966 Added silc_server_send_notify_server_signoff to send the
3967 SERVER_SIGNOFF notify type. Deprecates the function
3968 silc_server_send_remove_id.
3970 Added also silc_server_send_notify_signoff to send the
3971 SIGNOFF notify type.
3973 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3974 SILC protocol from this day on. Changed the protocol
3975 specification as well.
3977 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3978 notify type. It is used between routers to notify about
3979 topic changes on a channel.
3981 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3984 * Partly updated the protocol specification to comply with the
3985 changes now made. It is still though a bit outdated.
3987 * The JOIN notify type now takes one extra argument <Channel ID>.
3988 The packet used to be destined to the channel but now the
3989 JOIN type may be sent as list thus it is impossible to
3990 destine it to any specific channel. By adding this argument
3991 it is again possible.
3993 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Added CREDITS file. The CHANGES and CREDITS file will appear
3996 in the distribution as well.
3998 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4001 types in the server's silcd/packet_receive.c.
4003 * Implemented CMODE and CUMODE to work in router environment.
4005 * Fixed minor encoding and decoding buglet from the
4006 lib/silccore/silcmode.c.
4008 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4011 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4013 * Changed all SilcConfigServer* and silc_config_server* to
4014 SilcServerConfig* and silc_server_config*, respectively.
4017 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4019 * Associated the ID (client or server ID) to the Authentication
4020 Payload to avoid any possibility of forging. Updated the
4021 protocol specification and the code accordingly.
4023 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * The RSA key length is now save to the RsaKey context in the
4026 key generation process in lib/silccrypt/rsa.c. The key length
4027 is now used to figure out the maximum size of the block allowed
4028 to be encrypted/signed.
4030 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4031 is equivalent to the silc_mp_mp2bin but does not allocate any
4034 * Changed silc_mp_mp2bin API to take length argument. If it is
4035 non-zero then the buffer is allocated that large. If zero, then
4036 the size is approximated using silc_mp_sizeinbase, which however
4039 * Created Global RNG API which is global RNG that application can
4040 initialize. After initializing, any routine anywhere in the
4041 code (including library) can use RNG without allocating a new
4042 RNG object. This was done to allow this sort of use of the
4043 RNG in code that has no chance to allocate RNG object. All
4044 applications currently allocate this and many routines in the
4045 library use this. Affected file lib/silccrypt/silcrng.[ch].
4047 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4048 it to use the Global RNG API.
4050 * Defined Authentication Payload into protocol specification that
4051 is used during SILC session to authenticate entities. It is
4052 used for example by client to authenticate itself to the server
4053 to obtain server operator privileges.
4055 Implemented this payload into the lib/silccore/silcauth.[ch].
4056 Implemented also routines for public key based authentication
4057 as the new protocol specification dictates.
4059 Moved definitions of different authentication methods from
4060 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4062 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4063 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4064 silc_pkcs_verify_with_hash functions into the file
4065 lib/silccrypt/silcpkcs.[ch].
4067 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * The client entry's userinfo pointer must be always valid.
4070 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4071 will fail since it requires the userinfo. Now, the userinfo
4072 is allocated as "" if actual userinfo does not exist. Actually,
4073 it must exist and it is totally Ok to drop client connections
4074 that does not announce the userinfo. However, we will make
4075 this workaround for now.
4077 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4078 to return the remote port by socket.
4080 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4083 SILC_SERVER_PENDING_EXEC and added an new macro
4084 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4085 data or when error occurs while processing the pending command.
4087 Added new argument `destructor' into silc_server_command_pending
4088 and to the SilcServerCommandPending object. This destructor is
4089 now called after calling the pending callback or if error occurs
4090 immediately. If error occurs the actual pending callback won't
4091 be called at all - only the destructor. The destructor may be
4092 NULL if destructor is not needed.
4094 All this applies for client library code as well. Similar
4095 changes were made there as well for the pending commands.
4097 In the client, the application must now allocate the
4098 SilcClientCommandContext with the silc_client_command_alloc
4101 * Added reference counter to the SilcServerCommandContext. Added
4102 function silc_server_command_alloc and silc_server_command_dup
4105 Same type of functions added to the client library for the same
4108 * Removed the cmd_ident from IDListData away since it is now
4109 global for all connections. It is the command identifier used
4110 in command sending and with pending commands. The affected file
4113 * Added reference counter to the SilcSocketConnection objecet to
4114 indicate the usage count of the object. The object won't be
4115 freed untill the reference counter hits zero. Currently only
4116 server uses this, and client ignores it. The client must be
4117 set to use this too later. The affected files are
4118 lib/silccore/silcsockconn.[ch]. Added also the function
4119 silc_socket_dup to increase the reference counter.
4121 This was mainly added because it is possible that the socket
4122 is removed underneath of pending command or other async
4123 operation. Now it won't be free'd and proper DISCONNECTING
4124 flags, etc. can be set to avoid sending data to connection that
4125 is not valid anymore.
4127 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4128 the connection. After that it sets SILC_SET_DISCONNECTED.
4129 It is, however, possible that the socket data is not still freed.
4130 The silc_server_packet_process now checks that data is not
4131 read or written to connection that is DISCONNECTED. The socket
4132 get's freed when the reference counter hits zero.
4134 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Changed the client operation API: channel_message operation's
4137 `sender' is now the client entry of the sender, not the nickname
4138 and the `channel' is the channel entry, not the channel name.
4140 In the private_message operation the `sender' is now also the
4141 client entry of the sender not the nickname.
4143 Affected file is lib/silcclient/ops.h and all applications
4144 using the client operations.
4146 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Moved the calling of ops->connect() from connect_to_server_final
4149 into receive_new_id functin since that is the point when the
4150 client is actually allowed to send traffic to network. The
4151 affected file is lib/silcclient/client.c.
4153 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4156 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4157 (if needs broadcasting) instead of broadcasting the packets one
4158 by one which would make a burst in the network traffic.
4160 * Added `broadcast' argument to the functions in silcd/server.[ch]
4161 silc_server_create_new_channel[_with_id] to indicate whether
4162 to send New Channel packet to primary router.
4164 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Added new function into the silcd/server.[ch] files:
4167 silc_server_create_new_channel_with_id to create new channel with
4168 already existing Channel ID.
4170 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4171 lib/silccore/silcpacket.h. This packet is used t send list of
4172 Set Mode payloads inside one packet. Server uses this to set
4173 the modes for the channels and clients on those channels, that it
4174 announced to the router when it connected to it. The protocol
4175 specification has been updated accordingly.
4177 * The silc_server_new_channel did not handle the packet coming
4178 from normal server as it normally does not send that. However,
4179 when it announces its channels it does send it. Implemented
4180 the support for that.
4182 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4183 into the file lib/silccore/id.h.
4185 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * Fixed memory leaks in the functions silc_idlist_del_client,
4188 silc_idlist_del_channel and silc_idlist_del_server in the file
4189 silcd/idlist.c. All of those leaked like a sieve.
4191 * Fixed some small memory leaks in the client's function
4192 silc_client_notify_by_server.
4194 * Added functions into silcd/server.c: silc_server_announce_clients,
4195 silc_server_announce_channels and silc_server_announce_server.
4196 These functions are used by normal and router server to announce
4197 to its primary router about clients, channels and servers (when
4198 router) that we own. This is done after we've connected to the
4201 These functions effectively implements the following packet types:
4202 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4203 and SILC_PACKET_NEW_ID_LIST.
4205 * Added new functions into the silcd/packet_receive.[ch]:
4206 silc_server_new_id_list, silc_server_new_channel_list and
4207 silc_server_new_channel_user_list to handle the incoming
4208 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4210 * Added support of changing Channel ID in the function
4211 silc_server_replace_id. If the server that announces a channel
4212 to the router already exists in the router (with same name but
4213 with different Channel ID), router is responsible to send
4214 Replace ID packet to the server and force the server to change
4215 the Channel ID to the one router has.
4217 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4218 client that the Channel ID has been changed by the router. The
4219 normal server sends this to the client. Client must start using
4220 the new Channel ID as the channel's ID.
4222 Implemented handling of this new type into lib/silcclient/client.c
4223 into the function silc_client_notify_by_server.
4225 * Added new function silc_idlist_replace_channel_id into the files
4226 silcd/idlist.[ch] to replace the Channel ID.
4228 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Call silc_server_command_identify_check always when processing
4231 the IDENTIFY command in silcd/command.c
4233 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4236 send keepalive packets. The packet can be sent by clients,
4237 servers and routers.
4239 Added function silc_socket_set_heartbeat into the file
4240 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4241 If not set, the heartbeat is not performed. The actual
4242 heartbeat is implemented in the low level socket connection
4243 library. However, application is responsible of actually
4246 Added silc_server_send_heartbeat to send the actual heartbeat
4247 packet into silcd/packet_send.[ch]. Server now performs
4248 keepalive with all connections.
4250 * Added silc_task_get_first function into lib/silcutil/silctask.c
4251 to return the timeout task with shortest timeout. There was a bug
4252 in task unregistration that caused problems. TODO has been
4253 updated to include that task system must be rewritten.
4255 * The client library will now resolve the client information when
4256 receiving JOIN notify from server for client that we know but
4257 have incomplete information.
4259 * Rewrote parts of silc_server_remove_from_channels and
4260 silc_server_remove_from_one_channel as they did not remove the
4261 channel in some circumstances even though they should've.
4263 * Encryption problem encountered in server:
4265 The LEAVE command used to send the Channel Key packet to the
4266 router immediately after generating it. However, the code
4267 had earlier sent Remove Channel user packet but not immediately,
4268 ie. it was put to queue. The order of packets in the router
4269 was that Channel Key packet was first and Remove Channel User
4270 packet was second, even though they were encrypted in the
4271 reverse order. For this reason, MAC check failed. Now, this
4272 is fixed by not sending the Channel Key packet immediately but
4273 putting it to queue. However, this is more fundamental problem:
4274 packets that are in queue should actually not be encrypted
4275 because packets that are sent immediately gets encrypted
4276 actually with wrong IV (and thus MAC check fails). So, packets
4277 that are in queue should be encrypted when they are sent to
4278 the wire and not when they put to the queue.
4280 However, the problem is that the current system has not been
4281 designed to work that way. Instead, the packet is encrypted
4282 as soon as possible and left to the queue. The queue is then
4283 just purged into wire. There won't be any fixes for this
4284 any time soon. So, the current semantic for packet sending
4287 o If you send packet to remote host and do not force the send
4288 (the packet will be in queue) then all subsequent packets to the
4289 same remote host must also be put to the queue. Only after the
4290 queue has been purged is it safe again to force the packet
4293 o If you send all packets immediately then it safe to send
4294 any of subsequent packets through the queue, however, after
4295 the first packet is put to queue then any subsequent packets
4296 must also be put to the queue.
4298 Follow these rules and everything works fine.
4300 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Added new function silc_server_remove_clients_by_server to
4303 remove all client entries from ID list when the server connection
4304 is lost. In this case it is also important to invalidate all
4305 client entires as they hold the invalid server entry. This
4306 fixes fatal bug when server has lost connection and will reconnect
4309 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Made some sanity checks to silc_server_daemonise like to check
4312 whether the requested user and group actually exists.
4314 * Added sanity check to SKE's silc_ske_responder_finish to check
4315 that the public and private key actually is valid.
4317 * Invalidate the client's nickname when receiving Replace ID
4318 packet and the Client ID is being replaced. This means that the
4319 server will query the nickname if someone needs it (client)
4322 * Sort the ID Cache in client library when the ID Cache data
4323 has changed (needs sorting).
4325 * Do not allow for SILC client to create several connections to
4326 several servers. The client does not support windows right now
4327 and generating multiple connections causes weird behaviour.
4329 Irssi-silc client does support windows and can handle several
4330 connections without problems, see: www.irssi.org and SILC plugin.
4332 * Fixed some places where client was added to the IDList. The
4333 rule of thumb is following (in order to get everything right):
4334 If the client is directly connected local client then the
4335 `connection' argument must be set and `router' argument must be
4336 NULL to silc_idlist_add_client function. If the client is not
4337 directly connected client then the `router' argument must
4338 bet set and the `connection' argument must be NULL to the
4339 silc_idlist_add_client function.
4341 * The funtion silc_server_packet_send_local_channel actually did
4342 not check whether the client was locally connected or not. It
4343 does that now. Fixed a bug related to LEAVE command.
4345 * Fixed Remove Channel User payload parsing bug in server's
4346 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4348 * The server's silc_server_save_channel_key now checks also the
4349 global ID list for the channel as it might not be in the local
4350 list. Fixed a bug related to LEAVE command.
4352 * Is this the end of the [<unknown>] buglet that has been lurking
4353 around for a long time? A little for loop fix in server's
4354 silc_server_command_whois_parse that is used by both IDENTIFY
4355 and WHOIS command. At least, this was a clear bug and a cause
4356 of one type of [<unknown>] buglet.
4358 * WHOIS and IDENTIFY commands call the function
4359 silc_server_command_[whois/identify]_check function even if
4360 we are not router server.
4362 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Added --with-gmp configuration option. If set the GMP
4365 is always compiled in the SILC source tree. If not set then
4366 it is checked whether the system has the GMP3 installed. If
4367 it has then the GMP won't be compiled (the system's headers
4368 and library is used), if it doesn't have it then the GMP is
4369 compiled in the SILC source tree.
4371 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Changed RSA private exponent generation to what PKCS #1
4374 suggests. We try to find the smallest possible d by doing
4375 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4376 not security fix but optimization.
4378 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Added new config entry [Identity] to fork the server and run
4381 it as specific user and group. A patch from Bostik.
4383 * Imported Dotconf configuration library into lib/dotconf.
4384 This will be used to create the SILC configuration files later.
4385 It will appear in the distsribution after this commit.
4387 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * A big code auditing weekend happening. Auditing code for
4390 obvious mistakes, bugs and errors. Also, removing any code
4393 Removed files for being obsolete:
4395 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4396 inline in the file lib/silcutil/silcbuffer.h)
4398 o lib/silcutil/silcbufutil.c (the header has inline versions)
4400 Changed code to fix possible error conditions:
4402 o The buffer formatting routines now check that the destination
4403 buffer really has enough space to add the data. This applies for
4404 both buffer formatting and unformatting
4405 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4406 unformatting was changed to accomodate following rules:
4407 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4408 sent to the function while XXX_*STRING will not allocate or copy
4409 the data into the buffer. Instead it sets the pointer from the
4410 buffer into the pointer sent as argument (XXX_*STRING used to
4411 require that the pointer must be allocated already). This change
4412 makes this whole thing a bit more consistent and more optimized
4413 (note that the data returned in the unformatting with XXX_*STRING
4414 must not be freed now). The routines return now -1 on error.
4416 o Tried to find all code that use buffer_format and buffer_unformat
4417 and added return value checking to prevent formatting and
4418 especially unformatting errors and possible subsequent fatal
4421 o Changed ske->x and ske->KEY to mallocated pointers in
4422 lib/silcske/silcske.h. Fixed possible data and memory leak.
4424 o Added return value checking to all *_parse* functions. Fixed
4425 many memory leaks as well.
4427 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4428 so that buffer overflows would not happen. All code now also
4429 checks the return value as it can fail.
4431 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Added reconnection support to server if the normal server looses
4434 its connection to the router (for example if router is rebooted).
4435 The server performs normal reconnection strategy implemented
4436 to the server. Affected file silcd/server.c.
4438 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Added new packet type SILC_PACKET_SET_MODE that is used to
4441 distribute the information about changed modes (for clients,
4442 channels and clients channel modes) to all routers in the
4443 network. Updated the protocol specification accordingly.
4445 Added functions into silcd/packet_send.c and
4446 silcd/packet_receive.c: silc_server_send_set_mode,
4447 silc_server_set_mode.
4449 Added new files silcmode.[ch] into lib/silccore that implements
4450 the encoding and decoding of Set Mode Payload. Added new type
4451 SilcSetModePayload. Moved the definitions of different modes
4452 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4454 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Oops, a little mistake in server's connection authentication
4457 protocol. The protocol is not ended with FAILURE but with
4458 SUCCESS if the authentication is Ok. :) Affected file is
4461 * Implemented NICK_CHANGE notify handling in server in the file
4462 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4463 the local clients on the channel. After the changing nickname
4464 in router environment snhould work and the [<unknown>] nickname
4465 should appear no more.
4467 The silc_server_replace_id function that receives the Replace ID
4468 payload now sends the NICK_CHANGE notify type also in the file
4469 silcd/packet_receive.c
4471 * Changed WHOIS and IDENTIFY command to support the maximum amount
4472 of arguments defined in protocol specs (3328 arguments). This
4473 fixed a bug that caused problems when there were more than three
4476 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Added extra parameter, command identifier, to the
4479 silc_client_send_command so that explicit command identifier
4482 Changed that ID list routines uses specific command identifier
4483 when sending WHOIS/IDENTIFY requests to the server so that they
4484 can be identified when the reply comes back.
4486 Affected files lib/silcclient/command.[ch],
4487 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4489 * Added `sender' argument to silc_server_packet_send_to_channel
4490 to indicaet the sender who originally sent the packet to us
4491 that we are now re-sending. Ignored if NULL. Affected file
4492 silcd/packet_send.[ch].
4494 * Added some server statistics support in silcd/server_internal.h
4495 SilcServerStatistics structure and around the server code. Also
4496 send some nice statistics information when client is connecting
4499 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed channel ID decoding in server's JOIN command reply in
4502 silcd/command_reply.c
4504 * Fixed braodcasting of replace ID payload to not to send it if
4505 we are standalone server in silcd/packet_receive.c.
4507 * Fixed all channel message sending routines to not to send
4508 packets to clients that has router set, since they are routed
4509 separately in the same function earlier. Affects file
4510 silcd/packet_send.c and all channel packet sending functions.
4512 * In USERS reply, res_argv[i] are not allocated, the table
4513 is allocated. Thus changed that free the table, not its
4516 * In server's whois_check and identify_check if the client is
4517 locally connected do not send any WHOIS commands - they are not
4520 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Fixed some minor bugs in client when sending WHOIS command. The
4523 arguments was in wrong order.
4525 * Removed statis function add_to_channel from server in
4526 silcd/command.c that was previously used with the joining but
4529 * Tested USERS command in router environment successfully with two
4530 routers, two servers and two clients.
4532 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Reorganized the USERS command and command reply in client library
4535 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4536 When the command is given by user we register a pending command
4537 callback that will reprocess the command after the reply has been
4538 received from the server. When reprocessing the packet we then
4539 display the information. Thus, the USERS information is displayed
4540 now in the command callback instead of in the command reply
4541 callback. The processing of the command is same as previously
4542 when server has sent the command reply in the JOINing process.
4544 * Added to USERS command in silcd/command_reply.c to join the client,
4545 we didn't use to know about, to the channel after we've created
4546 a client entry for it. Also, for clienet we did know already still
4547 check whether it is on the channel or not and add it if not.
4549 * Removed silc_server_command_join_notify as the function and its
4552 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Changed the client's pending command handling to the same as the
4555 server's pending command handling. It is also now possible to
4556 execute command reply functions from other command reply
4557 function as the function callbacks for commands and command
4558 replies are one and same. The pending commands are not static
4559 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4560 in client connection context. Thus, pending commands are server
4561 connection specific as it is convenient.
4563 Changed the function silc_client_command_pending and
4564 silc_client_command_pending_del and added new function
4565 silc_client_command_pending_check. Removed the
4566 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4569 * Added cmd_ident, current command identifier, to the client
4570 connection context in lib/silcclient/client.h to keep track on
4571 command identifiers used in command sending. Client's command reply
4572 function handling now supports the mandatory command identifiers.
4574 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4575 funtions in client to fully support pending command callbacks.
4577 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4578 as one of the arguments to the application in the command reply
4581 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4582 before first releasing SILC but came back. Now it is removed again
4583 and should come back nomore. The FORWARDED flag was used only
4584 by the JOINing procedure by forwarding the command packet to router.
4585 Now, the JOINing procedure has been changed to more generic (due
4586 to various router environment issues) and FORWARDED is not needed
4587 anymore for anything. The protocol specification is yet to be
4590 Now, removed silc_server_packet_forward from server and the flag
4591 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4593 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Renamed NAMES command to USERS command. The NAMES was named that
4596 due to historical reasons. Now it is renamed. Also, rewrote
4597 parts of the USERS command. The nickname list is not sent anymore
4598 by the server. Only Client ID and mode lists are sent in the USERS
4599 command. Changed this also to the protocol specification.
4601 The client now resolves the names and stuff after it receives
4602 the USERS list from the server when joining to the channel.
4604 * WHOIS and IDENTIFY commands has been changed to support multiple
4605 Client ID's per command. One can now search for multiple users
4606 in the network by sending only one WHOIS or IDENTIFY command.
4607 Changed the code and the protocol specifications.
4609 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4610 uses silc_server_command_whois_parse to parse the request. */
4612 * If normal server, do not parse the WHOIS and IDENTIFY requests
4613 before sending it to the router. Saves some time.
4615 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Fixed JOIN command on client library. Wrong number of arguments
4618 used to crash the client.
4620 * Added silc_server_channel_has_global function to check whether
4621 channel has global users or not.
4623 * Added silc_server_channel_has_local function to check whether channel
4624 has locally connected clients on the channel.
4626 * The silc_server_remove_from_one_channel now checks whether the
4627 channel has global users or not after given client was removed from
4628 the channel. It also checks whether the channel has local clients
4629 on the channel anymore. If it does not have then the channel entry
4630 is removed as it is not needed anymore.
4632 * The silc_server_notify now checks on JOIN notify whether the joining
4633 client is one of locally connected or global. If it is global then
4634 the channel has now global users on the channel and that is marked
4635 to the channel entry. Also, it now saves the global client to
4636 global list who is joining and JOINs it to the channel. This is
4637 for normal server, that is.
4639 Changed silc_server_send_notify_on_channel,
4640 silc_server_packet_relay_to_channel and
4641 silc_server_packet_send_to_channel check if we are normal server
4642 and client has router set (ie. global client) do not send the
4643 message to that client, as it is already routed to our router.
4645 * Implemented LEAVE notify type handling in silc_server_notify
4648 * Tested LEAVE command in router environment successfully. Tested
4649 with two routers, two servers and two clients.
4653 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4655 * Implemented SIGNOFF notify type handling in silc_server_notify
4658 * silc_server_remove_id now removes the client entry from all channels
4659 it has joined and thusly sends SIGNOFF notify type.
4661 * Rewrote the NAMES list generation in server by removing two excess
4662 loops. The lists are created now inside one loop.
4664 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * silc_server_remove_channel_user checks now also global list
4667 for channel and client.
4669 * silc_server_new_channel_user checks now both local and global
4670 list for channel and client. Fixed a bug in client id decoding.
4671 Used to decode wrong buffer.
4673 * silc_server_channel_message checks now both local and global
4674 list for channel entry.
4676 * Tested channel joining (hence JOIN) in router environment
4677 successfully. Tested with two routers, two servers and two
4680 * Tested channel message sending in router environment successfully.
4682 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Added silc_server_save_channel_key into server.[ch] to save the
4685 received channel key in Channel Key payload processing. It is
4686 also used in JOIN command reply handling.
4688 Equivalent function silc_client_save_channel_key added into
4689 client.[ch] into client library.
4691 * Changed JOIN command reply to send information whether the channel
4692 was created or not (is existing already) and the channel key
4693 payload. Changed protocol specs accordingly.
4695 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4696 the request was sent by ID and not by nickname. Crashed on
4699 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4702 now correctly save the received data.
4704 * silc_server_free_sock_user_data now notifies routers in the
4705 network about entities leaving the network.
4707 At the same time implemented functions silc_server_remove_id
4708 and silc_server_send_remove_id to receive and send REMOVE_ID
4709 packets. The packet is used to notify routers in the network
4710 about leaving entities. The ID removed will become invalid in
4713 * Added function silc_idlist_del_server into server. Removes and
4714 free's server entry from ID list.
4716 * silc_server_private_message function now checks, if we are router,
4717 that the destination ID really is valid ID, naturally.
4719 * In router when NEW_ID packet is received (for new client) the
4720 hash of the Client ID is saved in the ID Cache but the
4721 client->nickname is set to NULL, instead of putting the hash
4724 IDENTIFY command now also checks that client->nickname must be
4725 valid. If it is not if will request the data from the server who
4726 owns the client. Added new function
4727 silc_server_command_identify_check.
4729 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4730 to set the command to already allocated Command Payload.
4732 * Tested private message sending in router environment with two
4733 routers, two servers and two clients. Fixed minor bugs and now
4736 * Fixed segfault from client's NAMES command. Used to crash if
4739 * Forwarded packets must not be routed even if it is not destined
4740 to the receiver. Changed server code comply with this.
4742 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added `require_reverse_mapping' boolean value to ServerParams
4745 structure. If TRUE (not default) the server will require that
4746 the connecting host has fully qualified domain name.
4748 If the reverse mapping is not required and hostname could not be
4749 found the IP address is used as hostname.
4751 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Implemented version string checking to both client and server.
4754 The check is incomplete currently due to the abnormal version
4755 strings used in development version of SILC.
4757 * Changed all command functions in server to use the new
4760 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Changed char *data to unsigned char *data in ID Cache system to
4763 support binary data as ID Cache data. Changed code to support
4764 binary data in lib/silccore/idcache.c.
4766 * Renamed silc_server_packet_relay_command_reply to
4767 silc_server_command_reply as it is normal packet receiving
4768 function. Rewrote the function to accept command replys for
4769 servers and not only for clients.
4771 * Mark remote router always as registered server if we are connecting
4772 to it. Otherwise, commands sent by the router to us are ignored.
4774 * All ID List find routines now returns the ID Cache Entry pointer
4775 as well if requested.
4777 * WHOIS command works now in router environment, tested with two
4778 routers, two servers and two clients.
4780 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4781 in router environment (as it is almost equivalent to WHOIS) but
4782 hasn't been tested thoroughly. Added new functions:
4784 silc_server_command_identify_parse
4785 silc_server_command_identify_send_reply
4786 silc_server_command_identify_from_client
4787 silc_server_command_identify_from_server
4789 * Disabled route cache adding because adding two different ID's with
4790 same IP replaces the old cache entry thus giving wrong route.
4791 The entry->router->connection is always the fastest route anyway
4792 so route cache may not be needed. Of course, new routes maybe
4793 established after receiving the ID when the entry->router->connection
4794 might not be anymore the most optimal.
4796 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Add route cache for received ID for fast routing.
4800 * Added silc_server_packet_route to route received packet on router
4801 that is not destined to us.
4803 * Renamed silc_server_get_route to silc_server_route_get.
4805 * Added id_string and id_string_len fields into SilcServer to
4806 include encoded ServerID for fast comparing without excess
4807 encoding of the ID's.
4809 * Cleaned up WHOIS command on server side. Added following static
4812 silc_server_command_whois_parse
4813 silc_server_command_whois_check
4814 silc_server_command_whois_send_reply
4815 silc_server_command_whois_from_client
4816 silc_server_command_whois_from_server
4818 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4819 arguments in command replies. All command functions should be
4820 updated to use this macro.
4822 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Minor typo fixes on command reply handling on server.
4826 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added silc_server_command_add_to_channel internal routine to add
4829 the client to the channel after router has created the channel and
4830 sent command reply to the server.
4832 * Added generic silc_server_send_command to send any command from
4835 * Use static buffer with ID rendering instead of duplicating data.
4837 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Fixed a channel user mode bug when joining to a channel server gave
4840 everybody channel founder rights, oops.
4842 * We mark ourselves as the router of the incoming server connection
4843 if we are router ourselves. This way we can check in some packet
4844 sending functions whether it is locally connected server. For
4845 incoming router connections we put NULL.
4847 * For router sending packets locally means now always sending the
4848 packet cell wide; to local clients and local servers. For normal
4849 server sending packet locally means sending it to only local
4852 * Fixed the JOIN command to really work in router environment. If the
4853 channel is created it is always created by the router. Router is
4854 also responsible of making the initial joining to the channel,
4855 sending JOIN notify to the sending server and distributing
4856 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4857 does not exist server doesn't do anything else but forward the
4858 command to the router which performs everything.
4860 * Added silc_server_send_channel_key function to send the Channel Key
4863 * Added silc_server_create_channel_key to create new channel key. The
4864 channel key is now re-generated everytime someone joins or leaves
4865 a channel, as protocol dictates. Note: channel->key_len is the
4868 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4871 packet_receive.[ch] to separate packet sending and receiving
4872 routines. The server.[ch] now includes everything else including
4873 actual packet processing (writing and reading data) and other
4876 Renamed silc_server_private_message_send_internal to
4877 silc_server_send_private_message. The routine is still though
4878 used only to relay private messages as server does not send
4879 private messages itself.
4881 Renamed silc_server_new_channel to silc_server_create_new_channel
4882 and added new function sicl_server_new_channel that handles the
4883 incoming New Channel packet. Added also new sending function
4884 silc_server_send_new_channel to send New Channel Payload.
4886 * Added new function silc_server_notify to process incoming notify
4887 packet to the server/router. Server may then relay the notify
4888 to clients if needed.
4890 * Added new function silc_server_new_channel_user to process incoming
4891 New Channel User packet. Router will redistribute the packet and
4892 send JOIN notify to its local clients and locally connected servers
4893 if needed. Normal server will send JOIN notify to its local client
4894 on same channel when received this packet. Added also corresponding
4895 sending function silc_server_send_new_channel_user to sent the
4898 * Added boolean route argument to send_notif_to_channel and
4899 packet_send_to_channel functions to attempt to route the packet
4900 if it is TRUE and send only locally if it is FALSE.
4902 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * silc_server_replace_id now broadcasts the received replace ID
4905 packet if it is not broadcast packet already. The router must
4906 broadcast to inform other routers about changed ID.
4908 * Added backpointer to server's router into SilcServer context in
4909 silcd/server_internal.h.
4911 * Fixed silc_server_packet_broadcast to send correct broadcast
4914 * The channel key is now distributed to the local client as soon
4915 as it is received from the router (in router environment) so that
4916 no other packet may be sent for the channel until client has
4919 * silc_server_remove_channel_user now broadcasts the received
4920 Remove Channel User packet if it is not broadcast packet already.
4921 The router must broadcast to inform other routers about removed
4924 * Added users field into SilcPacketContext that is a reference count
4925 of the context. One can increase the reference count by calling
4926 silc_packet_context_dup which is now changed to just increase the
4927 reference count instead of duplicating the data. The reference
4928 count is decresed by calling silc_packet_context_free that will
4929 free the data after the reference count hits zero.
4931 For now on the packet context and everything allocated into it
4932 (including the raw packet from network) must be freed by calling
4933 the new silc_packet_context_free function. Added also new function
4934 silc_packet_context_alloc that must be used now to allocate the
4935 context. This also means that if a routine is asynchronous from
4936 silc_[client/server]_packet_parse_type the packet context must
4937 be duplicated by calling silc_packet_context_dup. Otherwise it
4938 gets free'd after silc_[client/server]_packet_parse_type returns.
4939 Also, one must remember that if packet is duplicated then its
4940 reference count must be decresed by calling the free function as
4941 many times as it was duplicated.
4943 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4944 from both client and server.
4946 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Made joining to a channel working in router environment.
4950 * Cleaned up JOIN command on server side and create function
4951 silc_server_command_join_channel internal routine to make the
4954 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Changed silc_command_pending list to SilcDList. Also, added
4957 `ident' field to SilcServerCommandPending structure to identify
4958 the reply and to call correct callback.
4960 Added silc_server_command_pending_check function to replace the
4961 corresnponding macro. The silc_command_pending list is not
4964 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4965 to set identifier to previously allocated Command Payload. It
4966 is used to set identifier for command when resending Command
4969 * Added silc_command_payload_encode_payload to encode Command
4970 Payload buffer from SilcCommandPayload structure.
4972 * Added silc_argument_payload_encode_payload to encode Argument
4973 payload buffer from SilcArgumentPayload structure.
4975 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Changed WHOIS command to support router connection on server side.
4978 The whois request is always sent to router unless the server is
4979 standalone server. After server has received the reply from the
4980 router will it send the reply to the client.
4982 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4983 broadcast received broadcast packet. The function is used only
4984 by router. The broadcast packet is always sent to the router's
4987 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4988 render given ID to printable string, for log files for example.
4990 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Made basic router to router connections working. At least they
4993 can now connect to each other but nothing really works the way
4994 they are supposed - yet.
4996 * Added new initiator token to RouterConnection configuration
4997 file in silcd/serverconfig.[ch]. It is used to tell whether we
4998 are the initiator to the remote router or whether we'll expect
4999 the other end to connect.
5001 * Moved registering of listener task to silc_server_init, hence
5002 the server starts listenning as soon as it is run, even if it
5003 does not have connections to other routers. Let's see how well
5006 * Changed default connection retry timeouts for more suitable in
5009 * Removed cipher and such arguments from silc_idlist_add_client
5010 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5011 Added new function silc_idlist_add_data to add the keys and stuff
5014 * Added SilcIDListData structure and added it to SilcClientEntry
5015 and SilcServerEntry as their first field in the structure. This
5016 way we can explicitly cast the ID entries to the SilcIDListData
5017 structure and get common data for the entries. In past, we had
5018 to first check what type of connection it is and then cast it to
5019 correct ID entry type. Now, we can directly cast the opaque
5020 pointer to the SilcIDListData (no matter what ID entry it actually
5021 is) and get the data needed.
5023 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5026 in some circumstances even if threre were timeout tasks, though not
5027 IO tasks, but tasks anyway. Now fixed.
5029 * Defined SilcServerConnection structure to hold connection specific
5030 stuff about directly connected servers and routers. The definition
5031 is currently in silcd/server_internal.h. I thought about having
5032 a bit more important role fro this struct but for now it is used
5033 only when connecting to other server (or router actually).
5035 * Added connecting retry support in server when connecting to
5036 router(s). The retry feature implement exponential backoff
5037 algorithm. Also, added SilcServerParams structure to hold default
5038 parameters for server. For now, it include these retry settings
5039 and are hard coded. After server is moded to be as Silc Server
5040 Library this structure will be more important.
5042 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Changed client librarys channel->clients table to SilcList and
5045 changed code accordingly.
5047 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Changed client's channel table to SilcList and changed code
5050 accordingly. Also changed SilcChannelClientEntry to include back-
5051 pointer to the channel so that client entry can use that structure
5052 as list as well and we have fast cross-reference to the channel.
5053 This change dramatically decreased the complexity of channel
5054 handling with client entry and vice versa (removed one extra
5055 loop when searching for channel entry from many functions).
5057 * Changed server->sim from table to SilcDList and changed code
5060 * NAMES command can now be used from user interface. It will show
5061 the user list on the channel, neatly.
5063 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5064 Code now saves realname of the user if it becomes available.
5066 * Renamed configure.in to configure.in.pre and made ./prepare
5067 script to automatically add correct version string to
5068 configure.in which it creates from configure.in.pre.
5070 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * NAMES command reply now shows users mode with the nickname when
5075 * Moved silc_client_ch[u]mode[_char] functions from
5076 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5077 place sucks, they are utility functions and should be in some
5080 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5082 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5085 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Added TRQ (efficient deque and list library) into lib/trq. This is
5090 a very good list library that is currently used in the SILC. Defined
5091 SilcList API over the library because I didn't like the API very
5092 much. See lib/trq/silclist.h for the API and examples of how to
5093 use the API. Fixed various places in the code to use the new
5094 SilcList API. The SilcList is meant for lists that has a structure
5095 already defined as a list. It is not suitable to add just some
5096 context to the list (in TRQ, the context is the list actually).
5098 So, I defined SilcDList that can be used for the purpose where
5099 predefined list structure does not exit. This can be used as
5100 such list. Now some context just can be added to the SilcDList.
5101 Currently this list is not used in the SILC just yet, though there
5102 are a lot places where this can replace dynamically allocated
5103 tables and I will fix these places, later, to use SilcDList.
5104 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5105 and use TRQ internally).
5107 Also fixed some annoying warning messages that the original TRQ
5108 code generated. Also minor changes to TRQ's Makefile.in.
5110 * Added support for querying by Client ID to both WHOIS and
5111 IDENTIFY commands into server, as required by the protocol.
5113 * Removed method function pointers from SilcBuffer structure. They
5114 weren't used to anything and just increased the context size for
5115 no good reason. This change also made silc_buffer_alloc and
5116 silc_buffer_free functions inline functions.
5118 * Disabled command flooding detection support until it's fixed so
5119 that it accepts commands in but does not execute them more than once
5122 * Added silc_net_localhost(), to return local hostname, into
5123 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5124 that must be initialized before calling silc_client_init.
5126 * Added new function: silc_server_send_notify_on_channels to send
5127 notify messages to all channels client has joined. It is assured
5128 that the message is sent only once per client.
5130 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5131 lib/silcutil/silcutil.[ch] as silc_format function. The new
5132 function is generic and is used by server as well, not only by
5133 the logging routines.
5135 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5136 the provided version string was not acceptable. Added new function:
5137 silc_ske_check_version into lib/silcske/silcske.h. The function
5138 must be implemented by the application (client or server) and it
5139 does not reside in the SKE library. The function checks the version
5140 string remote end sent.
5142 * Added back pointers (to opaque context and to SilcSocketConnection)
5143 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5145 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5146 duplicate packet context structure.
5148 * Changed `notify' client operation to send same arguments as client
5149 receives from server except for ID's. ID's are mapped to correct
5150 ID entry and that is returned. Also, if channel entry is not sent
5151 by server but the notify is for channel the channel entry is sent
5152 to application (otherwise application doesn't know that it is for
5153 channel (library gets it from packet's Destination ID)).
5155 * Added silc_client_remove_from_channels into client library to
5156 remove a client from all channels it has joined to. Used when
5157 received SIGNOFF notify from server. Added also new function
5158 silc_client_replace_from_channels to replace old ID entry with
5159 new ID entry on all channels. Used when received NICK_CHANGE
5162 * Fixed ID Cache list handling in silc_idlist_get_client in
5163 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5164 to get (or query) client by ID.
5166 * Updated TODO list.
5168 * Added connection authentication status message defined by the
5169 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5170 support for these into the code in client and server side.
5172 * Added generic function silc_client_send_command to send any command
5173 with variable argument list. Application should use this function
5174 to send commands if the command functions provided by the library
5175 does not suite for the application's user interface needs.
5177 * Added new `failure' client operation. Application is notified about
5178 received failure packet if client is executing a protocol. In this
5179 case the protocol's execution has failed.
5181 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5182 is required by the protocol.
5184 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5185 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5188 * Added status flag to SilcSKE object to indicate realtime status
5189 of the SKE protocol.
5191 * Application receives now exactly same command reply arguments as
5192 the library receives from server. However, if ID is received the
5193 corresponding ID entry is returned to the application (eg. Client
5194 ID is mapped to correct SilcClientEntry entry and that is returned).
5195 Changed command_reply client operation due to this change.
5197 * Changed all ID's in commands and in command replys as ID Payloads.
5198 Change affected both client and server side codes.
5200 All ID's sent in SILC network (with execption of ID's in SILC
5201 Packet header) are sent in ID Payload to support variable length
5204 * Server now notifies nick changes and notifies all clients on
5205 the channels about the new nickname (about the new Client ID,
5208 * Implemented CMODE command to change channel modes. Supports all
5209 channel modes defined by the protocol specs except ban and invite
5210 lists. (Also, private channel key mode is supported but support for
5211 setting private channel key in client is missing, thus, this mode
5212 has no effect on client side (except that server requires that the
5213 client uses private channel key and normal channel traffic does not
5216 Also, invite mode works per se, but INVITE command does not work
5217 yet correctly, so you can set channel as invite only channel but
5218 inviting clients to the channel does not work (it is yet to be
5219 thought what's the best way to do it).
5221 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5222 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5223 Implemented CUMODE command to change user's mode on the channel.
5224 Supports all modes defined by the protocol specs.
5226 * Added NAMES command reply to return users modes on the channel.
5228 * Removed unnecessary and slow ciphers from lib/silccrypt.
5230 * Set SO_KEEPALIVE option to connection sockets by default.
5232 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5234 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5235 redefined the Notify Payload into protocol specs.
5237 * Added silc_id_payload_parse_id to get ID directly from raw
5240 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5243 accept searching by Client ID as well.
5245 * Added support for LEAVE and SIGNOFF notify types in client library.
5247 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5248 to parse ID Payload from raw data.
5250 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added flags parameter into silc_ske_assemble_security_properties
5253 function in lib/silcske/silcske.[ch].
5255 * Changed notify client operation to fit better for notify messages
5256 sent by server. The notify payload received from server is now
5257 passed to the application (after parsing it to SilcNotifyPayload).
5258 It is application's responsibility to retrieve the arguments
5259 from the payload and show the message the way it wants. The message
5260 sent by server is implementation specific.
5262 * Changed public keys to comply with the protocol specification.
5263 Old public keys are not supported anymore and are not compatible.
5265 * Removed nickname from Channel Payload as the latest draft removed
5266 it. The client must resolve the nickname from the NAMES command
5267 reply received when it joined the channel.
5269 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5271 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Fixed some errors in protocol specification drafts.
5275 * Created lib/silccore/silcnotify.c to implement Notify Payload
5276 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5277 generic payloads described by protocol specifications. The file
5278 includes implementations for ID Payload and Argument Payload.
5280 * Changed Command Payload implementation to use the new Argument
5281 Payload. Changed command_xxxx_payload to command_payload_xxxx
5282 to comply with SILC coding conventions.
5284 * Added suppport for Argument Payload handling in Notify Payload
5285 implementation as protocol requires it. Added the new support
5286 into server and client lib as well.
5288 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Added support for multiple nicknames on same channel. [n] is
5291 added locally to the nickname if there are more than one same
5292 nicknames on the channel.
5294 * Server now sends all nicknames that matched WHOIS request.
5295 Client also shows the list received from server.
5297 * Added TOPIC command to client side. User can now set and show
5298 current topic on channel.
5300 * Added MOTD command to client and server. Also, server sends the
5301 motd when client connects to the server.
5303 * Changed version strings to comply ISO 8601.
5305 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Fixed protocol error handling in client library. It should now
5308 cope even if the SKE fails for some reason.
5310 * Made new protocol specification drafts for submitting to IETF.
5312 * Implemented TOPIC command to server in silcd/command.c.
5314 * Added two new notify types into lib/silccore/silcnotify.h:
5315 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5316 notify nickname change and topic setting/change on a channel.
5318 * API change of command_reply operation in client library. The
5319 application gets now the status type received from server as well.
5321 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5325 * Cras fixed and optimized the packet handling even further and
5326 it should work now. Minor change to the prototype of function
5327 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5329 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Added new function into lib/silcutil/silcschedule.[ch]:
5332 silc_schedule_with_fd to select() a specified fd. The function
5333 returns after timeout expires or data arrives or goes. The
5334 function is used by packet routines to wait that all data is
5335 received from network.
5337 * Fixed data reading from network in lib/silccore/silcpacket.c.
5338 The code now assures that all data is read from the fd and then
5339 continues packet processing. This was a bug fix since the code
5340 used to drop some data in some circumstances.
5342 * Added new function into lib/silcclient/client.[ch]:
5343 silc_client_start_key_exchange to start key exchange after
5344 connection has been established to server. The code internally
5345 now uses this funtion but its main purpose was to provide it
5346 for applications that perform their own connecting. After
5347 application has created a connection it merely calls this
5348 function to start the key exchange between client and server.
5349 The library takes care of everything else after that.
5351 Updated also lib/silcclient/README to explain the usage of
5354 * Do not send to application information that connection has
5355 been established. Application gets notified it by connect
5358 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Applied cras's patch to add silc_schedule_one function. The
5361 function runs scheduler once and returns.
5363 * Fixed the scheduler after cras messed it up. The timeout
5364 handling works now as it's supposed to work.
5366 * Added into lib/silccore/ silcnotify.h to include notify
5367 message types support. Changed silc_server_send_notify*
5368 functions, in server.[ch], to support those new notify types.
5369 Added the support for the notify types into client library,
5370 as well. Added new notify client operation into ops.h in
5373 * Changed silc_server_packet_send_to_channel to send normal
5374 packets instead of just channel message packets. The function
5375 is now used to send the notify packets to channels. It is not
5376 used to send channel message packets anymore, as server never
5379 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5380 va_arg()s as it seems to require it nowadays. I guess, if SILC
5381 is compiled with older va_arg() the new code should work anyway.
5383 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Splitted core library. Core library (lib/silccore) includes
5386 now only SILC protocol specific core (and common) components.
5387 Created new utility library (lib/silcutil) that includes more
5388 generic purpose stuff. The stuff for util library was taken
5389 from the old core library. This was minor and easy split.
5391 * Created SILC Client Library (lib/silcclient) that includes
5392 implementation of the SILC client without user interface. This
5393 was major move from silc/ directory. The code has been changed
5394 so that it is transparent towards the user interface. The
5395 silc/ directory includes now the same user interface as before
5396 and it uses the new client library. Read lib/silcclient/README.
5397 Basicly, the client library performs everything else related
5398 to SILC except user interface handling. Also, configuration
5399 files are considered to be part of user interface and library
5400 does not handle them.
5402 This change also changed a lot of structures, function naming etc.
5403 Most important change was that SilcClientWindow object was
5404 renamed to SilcClientConnection in the client library. Created
5405 also new file lib/silcclient/ops.h. Also added new files
5406 silc/local_command.[ch] and silc/client_ops.[ch].
5408 All these changes were made to make it easier for user interface
5409 designers to create what ever user interface for the SILC client
5412 It is also expected that the server will be moved to lib
5413 directory as well and SILC Server Library will be created;
5414 sometimes in the future.
5416 * Removed Local commands from lib/silccore/silccommand.h as
5417 they are application specific and new client library does not
5418 handle any of those anymore.
5420 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5421 old client implementation in silc/.
5423 * Added support for callback functions in SILC_LOG_* macros.
5424 Application can now set its own callbacks that will be called
5425 instead of using the default functions that will always print
5426 the debug messages to stderr (or stdout). Also, debugging can
5427 now be disabled by setting silc_debug to FALSE and re-enabled by
5428 setting it to TRUE. Note, that logging will still work even
5429 if debugging is disabled.
5431 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5432 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5433 silc_log_reset_debug_callbacks.
5435 * To enable debugging in silc client one must give now -d
5436 option on command line.
5438 * Changed silc_schedule_init to automatically allocate task queues
5439 if they are not allocated before calling it.
5441 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Added GMP 3.1 into math library.
5445 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5448 a channel in SILC network. The packet is used by servers and
5449 routers to notify other routers that user has left a channel.
5450 This little feature was missing until now. Added the feature
5451 to protocol specification as well.
5453 Added functions: silc_server_send_remove_channel_user and
5454 silc_server_remove_channel_user into server.[ch].
5456 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5457 lib/silccore/silcpacket.h. However, they are not implemented
5460 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Fixed joining to a channel and sending channel messages
5463 between server and router. The channel message sending should
5464 now work inside a cell.
5466 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Fixed the private message sending between server and router.
5469 The private message sending should now work inside a cell.
5471 * Added silc_server_replace_id into server.[ch] to replace
5472 existing ID in the SILC network.
5474 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5475 and silc_idlist_replace_server_id into idlist.[ch] in server.
5477 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Fixed the server to server connections. Server can again now
5480 connect to router. Router to router connections probably does
5483 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Added dynamic protocol registering support. Now protocols can
5486 registered and unregistered on the fly. Patch by cras.
5488 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Added lib/contrib directory to hold routines that some platforms
5491 don't have but are needed by SILC.
5493 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5494 into lin/contrib to provide getopt() and getopt_long() for
5495 those who don't have it.
5497 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Added AWAY command to client. When away message is set and
5500 client receives a private message packet the client automatically
5501 replies to the sender with the away message.
5503 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5504 bug seemed to be the cause of recent problems when compiling
5507 * Added version detection support to SKE protocol specification
5508 and added the new changes to the SKE implementation as well.
5509 There were other minor changes in the SKE protocol as well.
5511 Many changes in lib/silcske/silcske.[ch] and in
5512 lib/silcske/payload.[ch].
5514 * Added ^U functionality, clear input line. Patch from cras.
5516 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Mainly small bugfixes on core library. Fixed some debugging
5519 logging and buffer overflow in silclog.c.
5521 * Updated config.sub and config.guess on the distribution tree.
5523 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Added command lagging support in server. Client may execute
5526 commands now only once in two seconds.
5528 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Optimized packet reception. MAC computation and checking is now
5531 also more optimized. A lot previously duplicated code is now
5532 used as generic by both client and server.
5534 * Fixed key pair generation in clientutil.c
5536 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added into lib/silccore/silcbufutil.[ch] new function;
5539 silc_buffer_realloc.
5541 * Moved generic packet sending/encryption functions to
5542 lib/silccore/silcpacket.[ch] from client and server. Some
5543 rewriting of the functions.
5545 * Moved all generic packet reception/decryption functions to
5546 lib/silccore/silcpacket.[ch] from client and server. The
5547 packet processing is now much cleaner in both client and server.
5548 These were major changes in both client and server.
5550 * Created many common functions in server to do packet sending.
5551 Previously code were duplicated a lot, this has been removed
5554 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Rewrote major parts of the ID cache system. Don't know
5557 whether it is better now or not but at least the API is more
5560 * Major rewrite on ID cache stuff on client because of the ID
5561 cache API changes. Added idlist.c to client.
5563 * Also major rewrite on ID cache stuff on server as well.
5564 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5565 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5566 in hand, instead they are all put into the ID cache system now.
5567 All server_idlist_* routines uses ID cache now instead of
5568 traversing its own lists (those lists does not exist anymore).
5569 SilcIDList though still exists. Also, SilcXXXEntry's are
5572 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Finally made the SKE implementation compliant to the protocol
5575 specification. All mp integers are now binary encoded as
5576 opposed being HEX encoded.
5578 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5581 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5582 functions: silc_[encode/decode]_pem. Also added function
5583 silc_encode_pem_file to PEM encode with newlines ('\n') for
5586 * SILC public keys are now encoded either PEM or binary. Same
5587 option is for private keys as well. By default private keys
5588 are binary encoded and public keys PEM encoded. Silly HEX
5589 encoding were removed.
5591 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5592 function to create fingerprints.
5594 * Fixed a bug in SHA1; does not change the original data anymore.
5596 * Partly implemented INFO command on client and server side.
5597 Fixed CLEAR command. Changes to SERVER command; show current
5598 server(s) when giving command without arguments. Added
5599 VERSION command to client.
5601 * Added check to server that unregistered connections cannot
5602 execute commands (unless it is specificly allowed).
5604 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Fixed screen refresh.
5608 * Fixed channel joining bug from client. On some circumstances
5609 client tried to join to a channel it had already joined.
5611 * Added public key verification process into client's protocol.c.
5612 The client now verifies the public key from user and saves
5613 it into ~./silc/serverkeys/ directory.
5615 Added into: clientutil.[ch]: silc_client_verify_server_key.
5617 * Changed SKE protocol's silc_ske_initiator_finish function
5618 to accept callback function that verifies the received public
5619 key. Removed old silc_ske_verify_public_key function.
5621 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5624 silc_pkcs_private_key[_data]_set.
5626 * Made the password and public authentication more cleaner in
5627 server's protocol.c.
5629 * Removed historic and obsolete protocol `channel_auth' from
5630 both client and server.
5632 * Removed wrong way of sending command status messages from
5633 server to client in server's command.c. The old way violated
5634 protocol specification.
5636 Changes to silccore/silccommand.[ch]: removed
5637 silc_command_encode_status_payload -> not needed anymore,
5638 changed silc_command_encode_payload_va to accept extra
5639 argument on variable argument list. The argument type must
5640 now be provided to the function. Also, added new function:
5641 silc_command_encode_reply_payload_va which is same as
5642 normal command_encode_payload_va except command status type
5643 is provided as extra argument.
5645 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added ~./silc directory handling. The directory includes the
5648 public and private keys for the client.
5650 Added silc_client_check_silc_dir, silc_client_create_identifier
5651 and silc_client_load_keys.
5653 * Implemented SILC protocol compliant public key. Added public
5654 and private key saving to and loading from files.
5656 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5657 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5658 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5659 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5660 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5662 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5663 silc_pkcs_load_[public/private]_key.
5665 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added silc_server_get_route (route.[ch]) to get connection
5668 data for the fastest route for given ID.
5670 * Implemented INVITE command on client and server. The command
5671 were re-defined in the SILC Protocol Specification and the
5672 implementation now complies with the specification.
5674 * Implemented PING command on client and server.
5676 * Implemented NAMES command on client and server. The server side
5677 supports currently only normal server not router server yet.
5678 Some changes to NAMES definition in SILC protocol specification.
5680 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Implemented LEAVE command on client and server.
5684 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5685 again. This change was made to the protocol as well. Server
5686 should not violate the protocol specification anymore.
5688 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5691 was tested. SOCKS4 was not but should work anyway.
