3 * Do not process packet for disconnected socket connection.
4 Affected file lib/silccore/silcpacket.c.
6 * Process the DISCONNECT packet through scheduler in the
7 client library. Affected file lib/silcclient/client.c.
9 * Fixed the silc_client_packet_parse to not to increase
10 the packet sequence number if the conn->sock and the
11 current socket connection is not same. This can happen
12 for example during key agreement when the conn includes
13 multiple socket connections (listeners). Affected file
14 lib/silcclient/client.c.
16 * The sender of the file transfer request now provides also
17 the pointer (listener) for the key exchange protocol. If
18 the listener cannot be created then it sends empty key
19 agreement and lets the receiver provide the listener.
21 Added `local_ip' and `local_port' arguments to the
22 silc_client_file_send. If they are provided they are used,
23 if not then it will attempt to find local IP address, if
24 not found or bind fails then the remote client will provide
27 Affected files are lib/silcclient/client_ftp.c and
28 lib/silcclient/silcapi.h.
30 * Extended the FILE SEND command to support defining the
31 local IP and port for key exchange listener. They are
32 optional. Affected file irssi/src/silc/core/silc-servers.c.
34 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
36 * Defined to WHOIS command reply the sending of fingerprint
37 of the client's public key (if the proof of posession of the
38 corresponding private key is verified by the server).
39 Updated to the protocol specification.
41 * Added support of receiving the client's public key's
42 fingerprint in command reply in client library. Affected
43 file is lib/silcclient/command_reply.c, and
44 lib/silcclient/idlist.[ch].
46 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

57 twice for same socket context. Affected file is
60 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Send error message to application if opening file for
63 writing during file transfer fails. Affected file is
64 lib/silcclient/client_ftp.c.
66 Remove all file transfer sessions for a client that we're
67 removing from ID cache.
69 Affected file is lib/silcclient/client_ftp.c.

99 client library. Affected file lib/silcclient/client_prvmsg.c.
101 * Do not actually remove the client directly from ID cache
102 during SERVER_SIGNOFF, but invalidate it. This way we
103 preserve the WHOWAS info for the client. Affected file
106 * Fixed SERVER_SIGNOFF notify handling in the server. The
107 server is now able to process incoming SERVER_SIGNOFF notify
108 for a server that it doesn't even know about. It will remove
109 the clients provided in the notify. Affected file
110 silcd/packet_receive.c.
112 * Check for partial packet in data queue after every packet that
113 was found from the queue. Return and wait for more data if
114 there is partial data in queue. Affected file is

132 irssi/src/fe-common/silc/module-formats.[ch].
134 * Wrote a help file for FILE command.
136 * Added silc_rng_global_get_byte_fast to get not-so-secure
137 random data as fast as possible. Random data is read from
138 /dev/urandom if available and from the SILC RNG if not
139 available. It is used in padding generation. Affected file
140 lib/silccrypt/silcrng.[ch].
142 * All packets in client library are now processed synchronously.
143 Optimized packet processing a lot. Affected file
144 lib/silcclient/client.c.
146 * All server connection packets are processing synchronously
147 now in server, to optimize packet processing. Affected file
150 * Include files are installed now only in Toolkit distribution
151 if make install is given. Affected files: all Makefile.am's.
153 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
155 * Assure that silc_client_notify_by_server_resolve does not
156 resolve the client information multiple times. If it cannot
157 be found by the first it cannot be found at all. Affected
158 file lib/silcclient/client_notify.c.
160 * Fixed WHOWAS command reply calling. Affected file
161 lib/silcclient/command_reply.c.
163 * Removed all references to silc_idlist_get_client from the
164 Irssi SILC client since that call is internal call used by
165 the library. The Irssi SILC client will use now client
166 retrieval functions found in silcapi.h.
168 * Fixed a bug in resolving nickname info before sending
169 private message. It used freed memory. Affected file
170 irssi/src/silc/core/silc-servers.c.
172 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

191 * Added silc_net_localip to return local host's IP address.
192 Affected file lib/silcutil/silcnet.[ch].
194 * If key exchange or rekey protocol is active for a connection
195 parse all packets syncronously since there might be packets
196 in packet queue that we are not able to process without first
197 processing packets before them. Affected file silcd/server,
198 lib/silcclient/client.c.
200 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
201 whether library should continue processing the packet.
202 Affected file lib/silccore/silcpacket.h.

235 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
237 * Resolve the client info when received private message or
238 channel message for a client which nickname we don't know.
239 Affected files lib/silcclient/client_prvmsg.c and
240 lib/silcclient/client_channel.c.
242 * Do not crash in /KEY if client is not connected. Affected
243 file irssi/src/silc/core/silc-channels.c.
245 * Added SilcClientStatus field to the SilcClientEntry in the
246 lib/silcclient/idlist.h.
248 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
249 is incomplete and is being resolved, it won't be resolved
252 Make sure also that USERS command reply does not resolve
253 twice information. Affected file is
254 lib/silcclient/command_reply.c.
256 Make sure that silc_client_get_clients_by_list does not
257 resolve twice same information.
259 * Check for valid client->id in the silc_server_free_client_data.
260 Affected file silcd/server.c.

275 * Call the silc_server_udpate_servers_by_server in the
276 primary router that comes back online in the backup resuming
277 protocol. Otherwise it routes packets wrong. Affected file
278 silcd/server_util.[ch], silcd/server_backup.c.
280 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
282 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
283 lib/silcutil/silcbuffmt.[ch].
285 * Redefined the SILC packet header to include the padding
286 length. Affected file lib/silccore/silcpacket.[ch].
288 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
289 length for maximum padding up to 128 bytes). Affected
290 file lib/silccore/silcpacket.h.
292 * Removed all backwards support for old 0.5.x MAC thingies.
293 The SILC packet header change makes it impossible to be
294 backwards compatible.
296 * Send the ENDING packet with timeout in the backup resuming
297 protocol. This is to assure that all routers has connected
298 to the primary router. Affected file silcd/server_backup.c.
300 * Changed the RNG to take the first IV from random data. It
301 used to take it from zero actually. Changed the RNG also
302 to use /dev/urandom during session. /dev/random is used
303 in initialization. Affected file lib/silccrypt/silcrng.[ch].
305 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
307 * Changed the SILC packet header to have the first two bytes
308 (the packet length) encrypted. Affected files aroung the
309 code tree, lib/silccore/silcpacket.[ch]. Removed the
310 SilcPacketCheckDecrypt callback. It is not needed anymore
311 since the silc_packet_receive_process will determine now
312 whether the packet is normal or special.
314 * Implemented the unidirectional MAC keys. Affected files
315 lib/silcske/silcske.c, silcd/protocol.c and
316 lib/silcclient/protocol.c.
318 * Implemented the packet sequence number to the MAC computation.
319 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
320 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
321 lib/silcclient/protocol.c.
323 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
325 * Allow backup router to announce servers. All servers
326 announced by backup router are added to the global list
327 automatically. Update hte server's socket to our primary
328 router also when backup router announces a server.
329 Affected file silcd/packet_receive.c.
331 * Do not update the client->router in the function
332 silc_server_udpate_clients_by_server if the client is on
333 global list. We might fail to find any specific server
334 for locally connected clients and local cell clients. They
335 should still use the `from' and not `to' as client->router.
336 This fixes backup router resuming protocol. Affected file
339 * Decrease channel statistics count only if the channel
340 deletion worked. Affected files are silcd/server.c and
343 * Added silc_server_update_servers_by_server to update origin
344 of all server entries. Used during backup router protocol.
345 Affected files silcd/server_util.[ch], silcd/server.c. and
346 silcd/backup_router.c.
348 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
349 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
350 silc_hmac_get_hash and silc_hmac_get_name. Affected file
351 lib/silccrypt/silchmac.c.
353 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
355 * Assure that router cannot reroute the same channel message
356 to the sender. Affected file silcd/packet_receive.c.
358 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Made better checks that the channel message is not sent
361 to the router it came from. Affected file is
362 silcd/packet_send.c. Fixed memory leak too.
364 * Announce informations for incoming router connection, but
365 only after checking if it is replaced by backup router.
366 Affected file silcd/packet_receive.c.
368 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
370 * Fixed the backup resuming protocol to work in multiple
371 router environment. Affected file silcd/server_backup.c.
373 * Route packet only to one router in the function
374 silc_server_packet_send_to_channel. Affected file is
377 * Fixed silc_server_send_notify_dest to set the broadcast
378 flag. Fixed the silc_server_send_notify_topic to actually
379 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
380 Affected file silcd/packet_send.c.
382 * Changed the SFTP Filesystem interface. Changed the
383 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
384 the filesystem operation function. The SilcSFTPFilesystem
385 is now a context that is allocated by all filesystem allocation
386 functions and it already includes the operations structure
387 and filesystem specific context. It is given as argument
388 now to the silc_sftp_server_start. This made the interface
389 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
390 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
392 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
394 * Changed the backup router adding and getting interfaces
395 in the server. The router that will be replaced by the
396 specified backup router is now sent as argument. Affected
397 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
400 * Added silc_net_addr2bin_ne to return the binary form of
401 the IP address in network byte order. Affected files
402 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
404 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
406 * Check for existing server ID in silc_server_new_server
407 and in silc_server_connect_to_router_final and remove the
408 old entry if it exists. Affected file silcd/packet_receive.c,
411 * Send the channel message always to only one router, either
412 in upstream or downstream. Affected file is
415 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
417 * Wrote the definition of the backup resuming protocol to the
418 protocol specification.
420 * Removed one redundant channel key generation from normal
421 server during joining procedure. Removed one redundant
422 channel key sending from server to router during joining
423 procedure. Affected file silcd/command.c.
425 * Made minor bugfixes to the backup router resuming protocol.
426 Affected file silcd/server_backup.c, server.c.
428 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
430 * Added --disable-asm configuration option. Affected files
431 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
434 * Implemented the backup resuming protocol that is used to
435 resume the primary router position in the cell after the
436 primary router comes back online. Affected files
437 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
438 and silcd/server_util.[ch].
440 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
442 * Sleep two (2) seconds after sending QUIT command to server.
443 Affected file lib/silcclient/command.c.
445 * Assure that if outgoing data buffer is pending do not force
446 send any data. Affected file silcd/packet_send.c.
448 * Assure that if outgoing data buffer is pending do not force
449 send any data. Affected file lib/silcclient/client.c.
451 * Implemented the backup router support when the primary router
452 goes down. The servers and routers can now use the backup
453 router as new primary router without loosing connectivity.
455 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
457 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
458 in the server to indicate disabled entry. All data read
459 from the connection will be ignored and no data is sent
460 for entry that is disabled. Affected files are
461 silcd/idlist.h, silcd/server.c.
463 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Created SFTP client and server test programs in the
466 lib/silcsftp/tests directory.
468 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
470 * Implemented memory filesystem (virtual filesystem) for
471 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
474 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Implemented the SFTP (SSH File Transfer Protocol) to the
477 lib/silcsftp. It includes SFTP client and SFTP server
480 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Moved lib/silccore/silcprotocol.[ch] to the
483 lib/silcutil library.
485 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
486 take variable argument list pointer as argument. Affected
487 file lib/silcutil/silcbuffmt.[ch].
489 * Added silc_buffer_set function that is used to set data
490 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
491 Affected file lib/silcutil/silcbuffer.h.
493 * Changed various routines in the core library to use the new
494 silc_buffer_set instead of allocating new buffer only for
497 * Added 64-bit value formatting and unformatting support to the
498 silc_buffer_[un]format routines. Affected file is
499 lib/silcutil/silcbuffmt.[ch].
501 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
502 to includes/bitmove.h.
504 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
506 * Fixed channel user mode saving in client library. Affected
507 file lib/silcclient/command[_reply].c.
509 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * Defined the file transfer to the SILC Protocol. Added
512 new packet type SILC_PACKET_FTP and defined File Transfer
513 Payload. The mandatory file transfer protocol is SFTP
514 (SSH File Transfer Protocol). Affected file in addition
515 of the internet draft is lib/silccore/silcpacket.h.
517 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
518 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
519 is used as part of backup router protocol when the primary
520 router of the cell is back online and wishes to resume
521 the position as primary router.
523 * Redefined the MAC generation keys in the protocol. The
524 same key is not used anymore in both direction. Both
525 direction will now use different keys for sending and
526 receiving. This fixes a potential security flaw. This
527 change causes incompatibilities in the protocol.
529 * Redefined also the MAC computation from the packet.
530 An packet sequence number is now added to the MAC
531 computation. This prevents possible replay attacks against
532 the protocol. This change too causes incompatibilities
535 Added `sequence' field to the SilcPacketContext to hold
536 the current sequence number for the packet.
538 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
540 * Added `created' field to the SilcIDListData in the file
541 silcd/idlist.h to indicate the time when the entry was
544 * Added `created' field to the SilcChannelEntry too. Affected
547 * Added `creation_time' aguments to all the announcement functions
548 in the server. If it is provided then only the entries that
549 was created after the provided time frame are actually
550 announced. Affected file silcd/server.[ch].
552 * The protocol says that the Channel ID's IP address must be
553 based on the router's IP address. Added check for this in
554 the silc_server_new_channel when processing incoming New Channel
555 Payload. Affected file silcd/packet_receive.c.
557 * Print out the correct version with --version in SILC client.
558 Affected file irssi/src/silc/core/silc-core.c.
560 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
562 * Fixed WHOWAS command to check for completnes of the client
563 entry always, not just when the command is coming from client.
564 Affected file silcd/command.c.
566 * Added new function silc_server_packet_queue_purge to purge the
567 outgoing data queue to the network. After the function returns
568 it is guaranteed that the outgoing packet queue is empty.
569 Affected file silcd/packet_send.[ch].
571 * Purge the outgoing packet queue in the rekey protocol's final
572 callback to assure that all rekey packets go to the network
573 before quitting the protocol. Affected file silcd/server.c.
575 * Added silc_client_packet_queue_parse as similar function as
576 in server to the client library. The affected file is
577 lib/silcclient/client.c.
579 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Splitted silcd/server.c and created silcd/server_util.[ch]
582 for utility functions.
584 * Added new socket flag SILC_SF_DISABLED to indicate that the
585 connection is open but nothing can be sent to or received from
586 the connection. Affected file lib/silcutil/silsockconn.[ch].
587 The checking for disabled socket is checked in the low level
588 silc_socket_write and silc_socket_read functions.
590 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Allow only nicknames and channel names that fits into the
593 7-bit unsigned char ASCII set. Affected file silcd/command.c.
595 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
597 * When processing JOIN command reply in server check that if
598 the channel exists in our global list we'll move it the local
599 list. Affected file silcd/command_reply.c.
601 * Fixed the check whether client is joined on the channel already
602 in JOIN command. Affected file lib/silcclient/command.c.
604 * Fixed the JOIN command reply to check whether the channel
605 already exists. Affected file lib/silcclient/command_reply.c.
607 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Added silc_ske_status_string to map the SKE error numbers
610 to readable strings. The affected files are
611 lib/silcske/silcske[_status].[ch].
613 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
615 * Do not show the private channels on the WHOIS channel list
616 as it is not allowed by the protocol. The affected file is
619 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
621 * Assure that the packet length digged from the actual packet
622 is something sensible in the silc_packet_decrypt_rest_special
623 in lib/silccrypt/silcpacket.c.
625 * Free and NULL the allocated pointer in silc_hmac_alloc if
626 the HMAC allocation fails. The affected file is
627 lib/silccrypt/silchmac.c.
629 * Print the selected security properties to the log files in
630 the server. Affected file silcd/protocol.c.
632 * Add SKE's reference counter even if calling the completion
633 callback manually. Otherwise it goes negative, although it
634 does not cause any problems. The affected file is
635 lib/silcske/silcske.c.
637 * Remove the client entry with short timeout after giving the
638 KILL command. Affected file lib/silcclient/command.c.
640 * Fixed to send error reply in WHOIS and IDENTIFY commands in
641 case all found clients are already disconnected (WHOWAS would
642 found them) in the server. Affected file silcd/command.c.
644 * Update the last_receive (time of last data received) to be
645 updated only when received private or channel message so that
646 the idle time showed in WHOIS makes more sense.
648 * Added boolean field `valid' in to the SilcClientEntry in the
649 client library to indicate whether the entry is valid or not.
650 This fixes the nickname change bug on channel when changing
651 the nickname to be same than the old (like nick to Nick) the
652 nickname formatter doesn't set the new nick anymore to Nick@host.
653 Affected file lib/silcclient/idlist.[ch].
655 * Now actually fixed the nickname changing on disconnection.
656 Added new function silc_change_nick to the Irssi SILC Client.
657 Affected file irssi/src/silc/core/client_ops.c,
658 irssi/src/silc/core/silc-nicklist.[ch].
660 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Check that the public key exists in the GETKEY command before
663 trying to encode it. Affected file silcd/command.c.
665 * Print some notifications on received public keys with GETKEY
666 command in the Irssi SILC Client. Affected files are
667 irssi/src/fe-common/silc/module-formats.[ch],
668 irssi/src/silc/core/client_ops.c.
670 * Use IDENTIFY command to resolve the server information in the
671 GETKEY command instead of INFO command. Affected file
672 lib/silcclient/command.c.
674 * All command reply functions in the client library now calls
675 the pending command reply callbacks even if an error has
676 occurred. The server has done this a long time and now it was
677 time to move the client library to this as well. Now all
678 errors can be delivered back to the pending command reply
679 callbacks if necessary. Affected files are
680 lib/silcclient/command[_reply].[ch].
682 * Change the nickname on disconnection back to the username
683 because in reconnect the server will enforce it to it anyway.
684 Affected file irssi/src/silc/core/silc-servers.c.
686 * Fixed a config file parsing bug in the Irssi SILC client.
687 Affected file irssi/src/silc/core/clientconfig.c.
689 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
691 * When printing the channel mode on JOIN, verify that the
692 channel key and channel's HMAC are valid. Affected file
693 irssi/src/silc/core/client_ops.c.
695 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
697 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
698 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
699 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
701 * Removed channel key rekey task deleting from the function
702 silc_server_save_channel_key. Affected file silcd/server.c.
703 Added explicit timeout task context instead that is used to
704 delete the task if we are registering a new task before the
705 new task has elapsed.
707 * When channel key rekey occurs the client library now saves
708 the old channel key for a short period of time (10 seconds) and
709 is able to use it in case some is still sending channel
710 messages encrypted with the old key after the rekey. Affected
711 file lib/silcclient/[idlist.h|client_channel.c].
713 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Added check to the silc_server_new_id_real to not accept
716 new ID if it is the sender's own ID. Affected file is
717 silcd/packet_receive.c.
719 * Assure that we do not announce ourself or the one we've
720 sending our announcements when we're router and are announcing
721 servers to our primary router. Affected file silcd/server.c.
723 * Fixed silc_server_command_identify_check_client to assemble
724 correct WHOIS packet. It send corrupted WHOIS packet and
725 caused problem with router to router connections. Affected
726 file silcd/command.c.
728 Fixed also silc_server_command_whois_check the same way
729 as for the IDENTIFY command.
731 * Added new SilcIDListStatus to the server in the SilcIDListData
732 structure. The status now includes the current status of
733 the entry (like registered, resolved etc.). Affected file
734 silcd/idlist.[ch]. Defined a bunch of different status types
735 as well. This replaced the old boolean registered field as well.
737 Added resolve_cmd_ident field to the SilcClientEntry structure
738 too so that if the entry is for example being resolved so
739 another command may attach to the same pending command reply
740 without requiring to resolve the same entry again. This concept
741 should optimize the WHOIS and the IDENTIFY resolving under
742 heavy load by taking away unnecessary resolving for entries
743 that are being resolved already.
745 Added support for adding multiple pending commands for one
746 command idenfier. Affected file silcd/command[_reply].[ch].
748 * Fixed WHOIS and IDENTIFY save to remove the cache entry
749 before deleting the data. Otherwise the hash table will have
750 freed data in comparison functions. Affected file is
751 silcd/command_reply.c.
753 * Fixed silc_idlist_replace_client_id to add the new entry to
754 the cache with NULL nickname. Otherwise there will be invalid
755 memory as the nickname after the nickname is freed. Affected
756 file silcd/packet_receive.c.
758 * Fixed the silc_idlist_get_clients_by_hash. The entries was
759 saved into wrong slots because the previous number of entries
760 was not taken into account. Affected file silcd/idlist.c.
761 Fixed same thing in silc_idlist_get_clients_by_nickname too.
763 * If we are router and we receive JOIN notify to a channel that
764 does not have any users then notified client is marked as the
765 channel founder, as it is it. The affected file is
766 silcd/packet_receive.c
768 * Added to the extended hash table API's table_del_*ext functions
769 the destructor as argument too, so that the caller can decide
770 which destructor to use or whether to use destructor at all.
771 Affected file lib/silcutil/silchashtable.[ch].
773 * Fixed ID Cache purging. It actually deleted the entries from
774 the hash table after the data was freed. The hash table ended
775 up comparing freed memory. The affected file is
776 lib/silccore/silcidcache.c.
778 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
780 * Fixed Irssi SILC client's KILL command's HELP syntax.
782 * The USERS command now resolves the detailed user information
783 if the userinfo field is missing. Affected file is
784 lib/silcclient/command_reply.c.
786 * Do not print error in silc_file_read if the read file does
787 not exist. Just silently return NULL. Affected file is
788 lib/silcutil/silcutil.c.
790 * Fixed the silc_log_output to not wine about NULL filename
791 and to not create some bogus " " filename. Affected file is
792 lib/silcutil/silclog.c.
794 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
796 * Fixed various printing bugs on the user interface in the
797 Irssi SILC Client. Minor changes that were forgotten from
800 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
802 * Fixed the configure.in.pre and the compilation and distribution
803 environment to support the new autoconf 2.52. That version is
804 now required to compile the CVS trunk.
806 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
808 * Renamed function silc_parse_nickname to silc_parse_userfqdn
809 to generally parse user@fqdn format strings. Affected file
810 lib/silcutil/silcutil.c.
812 * Added nickname_format and nickname_force_format fields to the
813 SilcClientParams structure. The first one defines the format
814 for the nicknames that the library will enforce if the receives
815 multiple same nicknames. The second one is boolean value and
816 can be used to force the library to always enforce the format
817 to the nicknames regardles whether there are multiple nicknames
818 or not. This configurable formatting was employed to flexibly
819 support accessing multiple nicknames from the user interface.
820 The userinterface can now set the nicknames to what ever format
821 they prefer. Affected file lib/silcclient/silcapi.h.
823 Added function silc_client_nickname_format to the file
824 lib/silcclient/idlist.c. It performs the nickname formatting.
826 Added new field `hostname´ to the SilcClientEntry context.
827 It holds the hostname of the client. Affected file is
828 lib/silcclient/idlist.h.
830 * Irssi SILC Client sets the nicknames in nick@hostn format.
831 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
832 irssi/src/silc/core/silc-core.c.
834 The WHOIS printing now also shows both the real nickname and
835 the formatted nickname so that user knows how to access the
836 user if there are multiple same nicknames cached. Affected
837 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
838 printing formatting too to take the hostname now as a separate
839 argument. The Affected file is
840 irssi/src/fe-common/silc/modules-formats.[ch].
842 * Changed the silc_client_get_clients_local to accept the formatted
843 nickname as argument. It accepts the real nickname too but the
844 formatted nickname can be used to find the true entry from
845 multiple entries. Affected file lib/silcclient/silcapi.h and
846 lib/silcclient/idlist.c.
848 * Added nickname_format_parse field to the SilcClientParams.
849 It is a callback function provided by the application to parse
850 the nickname out of the formatted nickname string. The library
851 calls it to get the nickname from the formatted string. Since
852 the application generally knows better the format of the nickname
853 string it parses it instead of the library, even though library
854 encodes the formatted string. If the callback function is not
855 provided then the library will use the string as is. The
856 affected file is lib/silcclient/silcapi.h.
858 * All the nickname strings passed to the client library in
859 commands are now expected to be formatted nickname strings.
860 If the command does not support the formatted nickname string
861 it will assume that the sent string is the actual nickname.
862 Affected file lib/silcclient/command.c.
864 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Added public key authentication support to OPER and SILCOPER
867 commands in the client library. Affected file is
868 lib/silcclient/command.c.
870 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
872 * Changed the get_auth_methdod client operation to be asynchronous.
873 It can be async if the application resolves the authentication
874 method from the server during the negotiation. Added new
875 SilcGetAuthMeth completion callback that the application will
876 call after resolving the authentication method.
878 Added function silc_client_request_authentication_method that
879 the application can use to resolve the authentication method
880 from the server. Added also SilcConnectionAuthRequest callback
881 that the library will call after the server has replied. The
882 application can call this function if it does not know the
883 current authentication method.
885 Affected files are lib/silcclient/client.c and
886 lib/silcclient/silcapi.h.
888 * The Irssi SILC client now automatically resolves the authentication
889 method incase any configuration information is not present (and
890 currently there never is). The affected file is
891 irssi/src/silc/core/client_ops.c.
893 * Fixed public key authentication from the client library.
894 Affected file lib/silcclient/protocol.c. Changed also the
895 protocol specification about the public key authentication in
896 the connection authentication protocol. The actual data to be
897 signed is now computed with a hash function before signing.
899 * Fixed the public key authentication from the server as well.
900 Affected file silcd/protocol.c.
902 * Removed the mlock()'s from the memory allocation routines.
903 Affected file lib/silcutil/silcmemory.c. The ./configure does
904 not check anymore for the mlock(). Affected file is
907 * Fixed USERS command in server to allow the execution of the
908 command for private and secret channels if the client sending
909 the command is on the channel. Affected file silcd/command.c.
911 * Fixed silc_client_get_clients_local to return the clients
912 count correctly. It could return wrong value. Affected file
913 lib/silcclient/idlist.c.
915 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
918 types. The assembler optimizations seemed not to like 64-bit
919 data types. The assmebler optimizations thus are now enabled
920 also for BSD systems as opposed to only enable them for Linux.
922 * Do not check for threads at all on BSD systems. Affected
923 file configure.in.pre.
925 * Removed -n and -h options from the Irssi SILC Client since
926 they are not used in silc.
928 * Fixed the prime generation to assure that the first digit
929 of the generated random number is not zero since our conversion
930 routines does not like number strings that starts with zero
931 digit. If zero digit is seen the random number is regenerated.
932 This caused some corrupted RSA keys when the zero first digit
933 was met. Affected file lib/silcmath/silcprimegen.c.
935 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Fixed WIN32 configuration in the ./configure script.
938 Fixed to include xti.h on environments that has it.
939 Patches by Carsten Ilchmann and andrew.
941 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
943 * Changed the silc_id_create_client_id to be collision
944 resistant. It is now assured that there cannot be created
945 two same client ID's. I suspect that some weird bugs in
946 the server were actually caused by duplicate Client IDs.
947 Affected file silcd/serverid.[ch]. A router receiving
948 new ID now also assures and informs the sending server
949 if the ID caused collision.
951 * Changed the silc_id_create_channel_id to also assure that
952 there are no collisions.
954 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Statement about ignoring the Mutual Authentication flag when
957 performing rekey with PFS was a bit misleading. It is ignored
958 if it was set in the initial negotiation, it cannot be even
959 set in the rekey. Fixed in the ke-auth draft. Started the
960 new versions of the protocol drafts in the doc/.
962 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Fixed a bug in silc_client_command_identify_save when saving
965 new channel information. The channel name was no duplicated
966 and caused crash on exit. Affected file is
967 lib/silcclient/command_reply.c.
969 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Fixed the getkey command handling in the server. Send just
972 empty OK reply to the sender if the key could not be fetched
973 (but everything else was ok, like the key just was not available).
974 Changed the public key parameter to optional in the protocol
975 specs so that empty OK reply can be sent. Affected file
978 Added a message to Irssi SILC client to tell to user if the
979 server did not return a public key.
981 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
983 * Fixed a channel key regeneration bug. It registered new
984 timeout tasks exponentially until all system resources were
985 used. Affected file silcd/server.c.
987 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Added the SILC Document generator to the scripts/silcdoc.
990 It can be used to generate the Toolkit Reference Manual out
991 of the source tree. Internally it will also use the RoboDoc
992 generator now imported in util/robodoc.
994 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Added couple of return's in rekey protocol if error orccurred
997 during the protocol. The execution must be terminated.
998 Affected file silcd/protocol.c. Also, terminate the protocol
1001 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * The client's Client ID was created initally from the wrong
1004 nickname (it could have been in format nick@host) in the
1005 silc_server_new_client. Affected file silcd/packet_receive.c
1007 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Added some SILC_LOG_ERROR's to various error conditions
1010 if client could not be added to ID cache. Affected files
1011 silcd/packet_receive.c and silcd/server.c.
1013 * When client's sock->user_data is freed, NULL also the
1014 client->router and client->connection pointers. Added check
1015 for these pointers being NULL to various places around the
1016 code. Affected file silcd/server.c.
1018 * Added client->data.registered == TRUE checks to various
1019 places around the code to assure that unregistered client's
1020 are not handled when it is not allowed. Affected file
1023 * Added `bool registered' fields to all
1024 silc_idlist_[server|client]_get_* routines to indicate whether
1025 the fetched client needs to be registered or not. Affected
1026 file silcd/idlist.[ch].
1028 * Add your own entry as registered to the ID cache in the
1029 server. Affected file server.c.
1031 * Fixed a bug in silc_server_new_server. The SilcServer was
1032 set as the new server's context instead of SilcServerEntry.
1033 This naturally caused some weird bugs.
1035 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Do not delete the channel rekey task when adding it
1038 for in silc_server_create_channel_key.
1040 * Changed the silc_server_create_channel_key to return
1041 TRUE or FALSE to indicate the success of the channel key
1044 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * Fixed MSVC++ project files and added missing files to
1047 Makefiles under win32/.
1049 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Do not add TCP_NODELAY flag if the operating system
1052 does not have it defined. Affected files are
1053 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1055 * Fixed buffer overflow from Irssi SILC Client. Affected
1056 file irssi/src/fe-common/core/themes.c.
1058 * Fixed double free in client library in the file
1059 lib/silcclient/client.c when disconnecting from server.
1061 * Applied double free patch from cras to Irssi SILC client.
1062 Affected files irssi/src/core/[modules/expandos].c
1064 * Fixed the disconnection handling to Irssi SILC Client.
1065 The application must call silc_client_close_connection
1066 in ops->connect client operation in case of failure of
1067 the connection. Affected file is
1068 irssi/src/silc/core/client_ops.c.
1070 * Do not set sock->protocol to NULL in the function
1071 silc_client_close_connection after executing the protocol's
1072 final callback since the sock might not be valid anymore.
1073 Affected file lib/silcclient/client.c.
1075 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Do not enable SILC_THREADS if the linking with libpthread
1078 did not happen. Affected file configure.in.pre.
1080 * Added notion to protocol specification that server must
1081 verify the sent authentication payload with CMODE when
1082 setting the channel founder key. Implemented it to the
1083 server. Affected file silcd/command.c.
1085 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Added _EXTRA_DIST SILC distribution variable to the
1088 distributions file. It is used to conditionally add extra
1089 files or directories to the specific distribution. Affected
1090 files ./prepare, Makefile.am.pre and distributions.
1092 Removed the `_' from the start of the distribution names.
1095 * Added README.WIN32 for instructions to compile the Toolkit
1098 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1100 * Fixed a double free in disconnection in the server. Affected
1101 file is silcd/server.c.
1103 * Fixed the lib/silcske/groups.c to work now also with GMP
1104 MP library. The string conversion did not work when using
1105 specific base and the base is indicated in the string as well.
1107 * Created win32/ directory which now includes MSVC++ specific
1108 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1109 It will appear only in the toolkit distribution
1111 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Changed the key material distribution function in case when
1114 the hash output is too short. The data is now concatenated
1115 a bit differently than it used to. Made the change to the
1116 SKE protocol specification.
1118 * Added better GMP detection to configure.in.pre. A patch
1121 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Fixed a minor bug in SKE that might cause some problem on
1124 some platforms. Affected file lib/silcske/silcske.c.
1126 * Added the cookie checking for initiator in the SKE. It checks
1127 that the responder returns the sent cookie unmodified. The
1128 affected file is lib/silcske/silcske.c. Added new SKE
1129 error type INVALID_COOKIE that can be sent during the
1130 negotiation. Fixed some memory leaks as well.
1132 * Added the "invalid cookie" error message to Irssi SILC client's
1135 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1137 * Added `task_max' field to the SilcClientParams to indicate
1138 the maximum tasks the scheduler can handle. If set to zero,
1139 default values are used. Affected file lib/silcclient/silcapi.h.
1141 * Fixed memory leaks in silc_client_close_connection. Affected
1142 file lib/silcclient/client.c.
1144 * Added silc_client_del_client_entry to client library to free
1145 all memory of given client entry. Affected file is
1146 lib/silcclient/idlist.[ch].
1148 * Added new functions silc_client_del_channel and
1149 silc_client_del_server to delete channel and server entries.
1150 Affected file lib/silcclient/[silcapi.h/idlist.c].
1152 * Removed silc_client_del_client_by_id from silcapi.h.
1154 * Fixed the INFO command to return the server's own info
1155 correctly when querying by Server ID. Affected file is
1158 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1160 * Removed the non-blocking settings in WIN32 code in the
1161 silc_sock_[read/write] and added SleepEx instead. Affected
1162 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1163 of input data is now checked with FIONREAD and ioctlsocket.
1165 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Call silc_schedule_task_del_by_context in the
1168 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1169 Affected file lib/silccore/silcprotocol.c.
1171 * Call silc_protocol_cancel for active protocols in the
1172 silc_server_close_connection if the funtion
1173 silc_server_free_sock_user_data has not been called.
1174 Affected file silcd/server.c.
1176 * Generic tasks cannot be deleted using the del_by_fd
1177 task deleting function since generic tasks does not match
1178 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1180 * Added a notion to SILCOPER help file that the SILCOPER works
1181 only on router server, not on normal server.
1183 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Added for WIN32 support for the new scheduler as well.
1186 Affected file lib/silcutil/win32/silcwin32schedule.c.
1188 * Fixed the SHA1 implementation to work on various platforms.
1190 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1193 API. It is part of the scheduler now. Everything else is
1194 as previously but some functions has changed their names.
1195 Checkout the lib/silcutil/silcschedule.h for the interface.
1196 Updated all applications to use the new interface. Affected
1197 files are lib/silcutil/silcschedule.[ch].
1199 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Found a bug in the SKE implementation. The HASH value,
1202 specified by the protocol, was not computed correctly. The
1203 public key of the responder was not added to the computation
1204 even though it is mandatory. Affected file lib/silcske/silcske.c.
1205 This unfortunately causes incompatibilities with older
1206 clients and servers.
1208 * Added WIN32 specific network init and uninit functions:
1209 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1210 the Winsock2. Affected file lib/silcutil/silcnet.h and
1211 lib/silcutil/win32/silcwin32net.c.
1213 * Set the socket always to nonblocking mode on WIN32 after
1214 reading data or writing data. Affected file is
1215 lib/silcutil/win32/silcwin32sockconn.c.
1217 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Fixed various compilation problems under WIN32. Affected
1220 files lib/silcutil/win32/silcwin32thread.c and
1221 lib/silcutil/win32/silcwin32schedule.c.
1223 * Removed all _internal.h #includes from public header
1224 files. Internal headers must never be included from
1227 Removed also the lib/silcske/payload_internal.h file.
1229 * All include files that may be needed (public and some others
1230 included by the public headers) by application developers are
1231 now copied to the ./includes directory. It does not copy any
1232 internal headers. Affected file Makefile.defines.pre and all
1233 Makefile.am's under lib/ and subdirs.
1235 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Do not change the ~/.silc directory's permissions automatically.
1238 Affected file irssi/src/silc/core/clientutil.c.
1240 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1242 * Do not cancel the protocol in silc_server_close_connection
1243 it might cause recursion. Now cancelled in the function
1244 silc_server_free_sock_user_data. Affected file silcd/server.c.
1246 * Fixed the silc_server_remove_clients_by_server to regenerate
1247 the channel keys correctly finally. Added also new function
1248 silc_server_remove_clients_channels to actually do it.
1249 Affected file silcd/server.c.
1251 * Fixed the silc_server_new_channel to not crash by giving
1252 wrong router to the new channel. Affected file is
1253 silcd/packet_receive.c.
1255 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1258 which is given as argument to the silc_client_alloc now.
1259 It can be used to configure the client and set various parameters
1260 that affect the function of the client.
1262 * The USERS command in server did not check whether the channel
1263 is private or secret. Affected file silcd/command.c.
1265 * Added new argument to the USERS command in protocol specification.
1266 The USERS command now can take the channel name as argument
1267 as well. Added support for this in client and server and
1268 updated the protocol specs.
1270 * Completed the GETKEY command in client. It can be now used
1271 to fetch also servers public key not only some clients.
1272 Affected files lib/silcclient/command[_reply].c.
1274 * Added silc_client_get_server to return server entry by the
1275 server name. Affected files lib/silcclient/silcapi.h and
1278 * Redefined the IDENTIFY command in protocol specification to be
1279 more generic. It now can be used to query information about
1280 any entity in the SILC Network, including clients, servers and
1281 channels. The query may be based either the entity's name
1282 or the ID. Added support for this in both client and server.
1284 Affected files silcd/command.c and lib/silcclient/command.c
1285 and command_reply.c.
1287 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1288 the _from_client and _from_server functions. Affected file
1291 * Added silc_client_get_channel_by_id_resolve to the file
1292 lib/silcclient/silcapi.h to resolve channel information by
1293 its ID. Added also silc_client_get_channel_by_id that
1294 does not resolve it from the server.
1296 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Added SilcServerEntry context into the client library
1299 to represent one server. The INFO command now allocates
1300 these to save the resolved server info. For now on the
1301 client library will also keep information about servers,
1302 connected and resolved with INFO.
1304 The INFO command now allocates the SilcServerEntry context
1305 and saves the server info there. The COMMAND_REPLY in
1306 the INFO now returns the parameters to application in
1307 same order as defined in the protocol specification.
1309 The entries are cached in the client->server_cache.
1311 * The INFO command is now issued after received the Client ID
1312 from the server. Affected file lib/silcclient/client.c.
1314 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1315 to the application as the mode changer might be server.
1316 It is guaranteed that NULL is not returned anymore to the
1317 application. Affected file lib/silcclient/client_notify.c.
1319 The ID Type is now also passed to the application so that
1320 it can check whether the returned entry is SilcClientEntry
1323 Added new function silc_client_get_server_by_id to return
1324 the server entry by ID. Affected files are the
1325 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1327 * Do not create the channel in the Irssi SILC Client when issuing
1328 the JOIN command but when received the sucessful JOIN command
1329 reply. Otherwise the channel might get created even though we
1330 could not join it. The Affected file is
1331 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1333 * Fixed a channel joining bug in router. The router must also
1334 check the channel modes, invite and ban lists etc. when serving
1335 the JOIN command sent by normal server. Affected file is
1336 silcd/command.c. The router now resolves the client's
1337 information from the server who sent the JOIN command if it
1338 does not know it, and processes the JOIN command only after
1341 * Changed the SilcCommandCb to take new argument; void *context2.
1342 Affected file lib/silccore/silccommand.h
1344 The second argument in the command callbacks in the server now
1345 includes the SilcServerCommandReplyContext if the command was
1346 called as pending command callback from the command reply.
1347 Otherwise it is NULL. When called as pending the status of the
1348 command reply will be checked and if it was erronous the
1349 error will be sent to the original sender of the command.
1350 This way the client always receives the error messages even
1351 though the server was actually the one who received the error
1352 when it resent the command to router, for example. Affected
1353 files silcd/command[_reply].[ch].
1355 * Fixed sending WHOWAS command's error message to client if
1356 the requested client could not be found. It was missing.
1359 * Changed the CMODE and CUMODE commands reply arguments in the
1360 protocol specification. The Channel ID is now sent in both
1361 of the commands to identify the channel. Implemented this
1362 new feature to the client and server. Affected files
1363 lib/silcclient/command_reply.c and silcd/command.c.
1365 * Made better checks for invite and ban lists in the JOIN
1366 command in server. Affected file silcd/command.c.
1368 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * The server now performs the incoming host IP/DNS lookup
1371 using the silc_socket_host_lookup and thus does not block
1372 the server anymore. Affected file silcd/server.c.
1374 * Completed the multi-thread support for SILC Scheduler in
1375 the lib/silcutil/silcschedule.c.
1377 * Fixed the configure.in.pre to detect the pthread correctly
1380 * Fixed a deadlock in silc_task_queue_wakeup in the file
1381 lib/silcutil/silctask.c.
1383 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Added new function silc_schedule_wakeup that is used in
1386 multi-threaded environment to wakeup the main thread's
1387 schduler. It needs to be used when a thread adds a new task
1388 or removes a task from task queues. After waking up, the
1389 scheduler will detect the task queue changes. If threads
1390 support is not compiled in this function has no effect.
1391 Implemented the wakeup mechanism to both Unix and WIN32
1392 systems. Affected files are lib/silcutil/silcschedule.[ch],
1393 lib/silcutil/unix/silcunixschedule.c and the
1394 lib/silcutil/win32/silcwin32schedule.c.
1396 * Added new function silc_task_queue_wakeup to wakeup the
1397 scheduler by the specified task queue. Affected file
1398 lib/silcutil/silctask.[ch].
1400 * The silc_socket_host_lookup_start now wakes up the scheduler
1401 after adding the timeout task. Affected file is
1402 lib/silcutil/silcsockconn.c.
1404 * The silc_socket_host_lookup is synchronous now if the threads
1405 support is not compiled in. However, the callback is still
1406 called asyncronously through the scheduler, anyway. Affected
1407 file lib/silcutil/silcsockconn.c.
1409 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Added new function silc_socket_host_lookup to perform
1412 asynchronous IP and FQDN lookups for the socket connection.
1413 Affected files lib/silcutil/silcsockconn.[ch].
1415 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1418 that may or may not compile the mutex support in.
1420 Changed the silc_mutex_alloc interface. It allocates the
1421 mutex now to the sent pointer and returns TRUE or FALSE.
1423 Affected file lib/silcutil/silcmutex.h.
1425 * Wrote the SILC Task Queue interface to support multi-threads.
1426 Affected file lib/silcutil/silctask.[ch].
1428 * Wrote the SILC Scheduler to support multi-threads. Affected
1429 file lib/silcutil/silcschedule.c.
1431 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1434 in lib/silcutil/win32/.
1436 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Defined SILC Mutex API and SILC Thread API and implemented
1439 them for Unix. Affected files are
1440 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1441 lib/silcutil/unix/silcunixmutex.c and
1442 lib/silcutil/unix/silcunixthread.c.
1444 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Fixed the silc_server_remove_clients_by_server's channel
1447 key re-generation. The hash table handling was incorrect
1448 and would not work with many channels. Affected file is
1451 * Fixed some memory leaks around the server code.
1453 * Rewrote the silc_server_get_users_on_channel to support IPv6
1454 based Client ID's. Affected file silcd/server.c.
1456 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1457 specification. However, a separate document must be written
1458 to define the detailed signing procedure and the payload
1459 associated with the flag. Defined the flag to the
1460 lib/silccore/silcchannel.h as well.
1462 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Changed the dynamic tables to static size tables in the
1465 lib/silccrypt/silchmac.c.
1467 * Removed GCC dependencies from the code. A patch by cras.
1469 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * Do not show the error "Error receiving packet bla bla"
1472 in server if it really was not an error (-2 means that reading
1473 is pending). Affected file silcd/server.c.
1475 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Fixed a possible crash in silc_server_remove_clients_by_server
1478 in silcd/server.c. Fixed there also some memory leaks.
1480 * Fixed the silc_idlist_replace_client_id. It could replace
1481 wrong key in the hash table. Affected file silcd/idlist.c.
1483 * Do not check whether there are global users on the channel
1484 if the channel->global_users is FALSE. Affected functions
1485 silc_server_remove_from_one_channel and
1486 silc_server_remove_from_channels in silcd/server.c. Also,
1487 do not check if the removed client is local as we can be
1488 sure that global client was not removed from the channel
1489 and checking for global users is not needed.
1491 * The silc_server_remove_clients_by_server now re-generates
1492 the channel keys correctly for those channels that had
1493 clients removed from them. Affected file silcd/server.c.
1495 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Found the reason of random crashes in the server. We weren't
1498 ignoring the SIGPIPE signal (which can be sent in write())
1499 and it crashed the server. Affected file silcd/silcd.c.
1501 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Assure that sock->user_data is not NULL in the function
1504 silc_server_packet_send in silcd/packet_send.c.
1506 * Disconnect the remote connection if it could not be added
1507 to any ID lists in the server. The affected file is
1510 * Check in silc_server_packet_send[_real/dest] that the
1511 socket is not disconnecting and ignore the data if it is.
1512 Affected file silcd/packet_send.c.
1514 * Define inline to __inline on native WIN32 compilation.
1515 Affected file includes/silcwin32.h.
1517 * Added some explicit type casts for inline code since MSVC
1518 require them. Affected files lib/silcutil/silcbuffer.h,
1519 lib/trq/silcdlist.h and lib/trq/silclist.h.
1521 * Print warning in log files from now on if the packet
1522 decryption fails. Affected file silcd/server.c.
1524 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Changed the `say' client operation's interface to accept
1527 new `type' argument to indicate the type of the message sent
1528 by the library. The application may filter the library's
1529 messages according the type. The affected file is the
1530 lib/silcclient/silcapi.h.
1532 * Added two new functions to lib/silcclient/silcapi.h:
1533 silc_client_del_client and silc_client_del_client_by_id.
1534 Affected file lib/silcclient/idlist.c.
1536 * Moved the clientincludes.h from includes/ to silc/ and
1537 serverincludes.h from includes/ to silcd/.
1539 * The modes for the CMODE and CUMODE are now passed as
1540 uint32 for application with COMMAND_REPLY. The affected
1541 file is lib/silcclient/command_reply.c.
1543 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * /WHOIS without arguments shows client's own information.
1546 Affected file lib/silcclient/command.c.
1548 * Changed PING to not accept any arguments. The specs
1549 says that client can ping only the connected server so
1550 requiring an argument is not needed. Affected file is
1551 lib/silcclient/command.c.
1553 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * Fixed a fatal bug in private message sending and reception
1556 encryption and decryption when using private message keys.
1557 The implementation was incorrect and did not follow the
1558 specification. It causd that some of the message were
1559 lost since it did not use the sending and receiving keys
1560 as the protocol suggests. This has been fixed and will cause
1561 incompatibilities with older clients when sending private
1562 message encrypted with private message keys. Affected files
1563 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1564 and various other in Irssi SILC Client.
1566 Added `responder' boolean argument to the functions
1567 silc_client_add_private_message_key[_ske] to indicate when
1568 the key is added as responder or initiator of the key
1571 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Removed the silc_ske_check_version function and created
1574 a SilcSKECheckVersion callback. Added also a function
1575 silc_ske_set_callbacks that is now used to set all SKE
1576 callbacks. The callback functions are not given to
1577 the SKE functions anymore, but this function is used to
1580 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1582 * Added `silc_version' argument to the silc_client_alloc
1583 to define the version of the application for the library.
1584 The library will use the version string to compare it
1585 against the remote host's (usually a server) version
1586 string. Affected file lib/silcclient/silcapi.h
1588 * Added the KE protocol context to Key Agreement context
1589 in client library so that we can abort the SKE if it
1590 is in process when we get timeout. Affected file is
1591 lib/silcclient/client_keyagr.c.
1593 * Do not resolve the client ID forever if it returns in the
1594 first time that such client does not exist. This was done
1595 for example with private message. Affected file is
1596 lib/silcclient/client_prvmsg.c.
1598 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Do not add regex.h for WIN32. The affected file
1601 includes/silcincludes.h.
1603 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1604 not work yet 100%. It generates the DLL's automatically
1605 when compiling with --with-win32 under cygwin.
1607 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * lib/contrib/regex.c is not compiled on WIN32.
1611 * Added silc_net_get_socket_opt function to the
1612 lib/silcutil/silcnet.h.
1614 * Added includes/silcwin32.h for WIN32 specific includes
1617 * Do not use ptime structure or any of the posix process
1618 functions on WIN32 in lib/silccrypt/silrng.c.
1620 * Added silc_gettimeofday to provide generic function
1621 for struct timeval on all platforms. Added the function
1622 to lib/silcutil/silcutil.h.
1624 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1627 library as they clearly belong there. As a plus side we
1628 can make the actual socket connection routines platform
1631 Added also new generic function silc_socket_read and
1632 silc_socket_write (that used to be silc_packet_[read/write].
1633 The implementation of these are platform specific.
1635 * Added WIN32 specific routines of silc_socket_[read/write]
1636 to lib/silcutil/win32/silcwin32sockconn.c.
1638 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Added preliminary support for native WIN32 compilation under
1641 cygwin (using the -mno-cygwin option for GCC) to the
1642 ./configure.in.pre. The --with-win32 now prepares the
1643 compilation for native WIN32.
1645 * Rewrote the SILC Scheduler interface in the file
1646 lib/silcutil/silcschedule.h. The scheduler is now context
1647 based and does not have anymore any global static scheduler.
1648 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1649 and created lib/silcutil/win32 directory for WIN32 based
1652 * Added Unix specific network routines to the
1653 lib/silcutil/unix/silcunixnet.c and the old
1654 lib/silcutil/silcnet.c includes now only generic routines.
1656 Added WIN32 specific network routines to the
1657 lib/silcutil/win32/silcwin32net.c.
1659 * Added Unix specific utility functions from the
1660 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1662 * Added WIN32 SILC Scheduler to the file
1663 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1666 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Do not handle JOIN notify in the server if the target client
1669 is not registered (idata->registered == FALSE). The affected
1670 file is silcd/packet_receive.c.
1672 * Update the nickrec->founder in event_cumode in the Irssi SILC
1673 client. Affected file irssi/src/silc/core/silc-channels.c.
1675 * Fixed the CUMODE_CHANGE notify handling in the server when
1676 server and router are announcing their clients on channels.
1677 Now the mode changes are saved and notified correctly. The
1678 affected file is /silcd/packet_receive.c.
1680 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1681 They really did not replace the cache entry in the ID Cache.
1682 Now they do that. Affected file silcd/idlist.c.
1684 * Fixed the KICK notify handling in the Irssi SILC client to
1685 update the channel records so that the kicked client does not
1686 appear to be on the channel. The affected file is
1687 irssi/src/silc/core/silc-channels.c.
1689 * Always update the conn->current_channel when executing command
1690 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1692 * Fixed the KILL notify handling in Irssi SILC client to remove
1693 the killed client on all channels.
1695 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * Fixed the silc_parse_command_line to remove extra spaces
1698 from the start and end of the arguments. Affected file is
1699 lib/silcutil/silcutil.c.
1701 * Cancel and free any active protocol in the function
1702 silc_server_close_connection. Affected file silcd/server.c.
1704 * Cancel and free any active protocol in the function
1705 silc_client_close_connction. Affected file is
1706 lib/silcclient/client.c.
1708 * Do not execute the KILL command for clients that are in
1709 history (ie. they are not in the network). Affected file is
1712 * Fixed KILL notify handling, client does not crash anymore.
1713 Affected file irssi/src/silc/core/silc-channels.c.
1715 * Reduced the default packet buffer size from 2048 to 1024 in
1716 lib/silccore/silcpacket.c.
1718 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1719 counter to the SKE context that is incresed when the SKE library
1720 performs async operation outside the library. If the outside
1721 process frees the SKE context and FREED status will be set
1722 and the library will detect after the sync operation that the
1723 libary is freed. The affected files are
1724 lib/silcske/silcske[_status].[ch].
1726 * Resolve the client entry information in the function
1727 silc_client_channel_message to assure that NULL pointer is not
1728 passed as client entry to the application. */
1730 * Fixed the task timeout calculation to assure that there is
1731 never negative timeouts. The affected file is
1732 lib/silcutil/silcschedule.c.
1734 * Fixed the channel user mode notification sending in server.
1735 It was sent point-to-point to the router (or to server by router)
1736 but it needs to be destined to a channel. The routines now
1737 supports sending the channel user mode notifys to the channels
1738 when announcing clients and channels. Affected files are
1739 silcd/server.c and silcd/packet_receive.c.
1741 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1742 It did not actually replace the old channel entry in the cache.
1743 Affected file lib/silcclient/client_notify.c.
1745 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Fixed a possible crash in silc_packet_send_prepare. It now
1748 assures always that there is enough space in the buffer and
1749 at the tail area of the buffer (for MAC).
1751 Fixed the inbound buffer reallocation in silc_packet_read.
1752 It was old code and did not handle the reallocation correctly.
1755 The affected file is lib/silccore/silcpacket.c.
1757 * Fixed buffer overflow in silc_parse_nickname in the file
1758 lib/silcutil/silcutil.c.
1760 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * make install generates new server keys only if there is not
1765 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1768 Added check that if the NOREPLY is set then we will not send
1769 the away message. This avoids infinite loop of away messages
1770 if both clients are away. The affected file is
1771 lib/silcclient/client_prvmsg.c.
1773 * Fixed client crash if /NICK was given without arguments.
1774 Affected file lib/silcclient/command.c.
1776 * Server does not send the invite list in INVITE command back
1777 to the client if the list was not altered. Added this notion
1778 to the protocol spec as well. Affected file silcd/command.c.
1780 Fixed possible crash in INVITE command by checking the
1781 value of silc_server_get_client_route command.
1783 * Fixed the INVITE notify type handling. The arguments are now
1784 taken in correct order and client does not crash. The affected
1785 file is irssi/src/silc/core/silc-channels.c.
1787 Removed the "Inviting xxx to channel" message from the
1788 client library away and let the application handle it.
1789 Affected file lib/silcclient/command.c. Added that message
1790 to Irssi SILC client's message formats.
1792 * Fixed CMODE command crash in client. It now checks the
1793 amount of arguments correctly and does not crash. The affected
1794 file is lib/silcclient/command.c.
1796 * Do not create new channel automatically in silc_channels_join
1797 but check whether the channel by that name already exists.
1798 Affected file irssi/silc/core/silc-channels.c.
1800 * Do not send the SERVER_SIGNOFF to router if the disconnected
1801 entity was the router. Affected file silcd/server.c.
1803 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1804 SILC client as it was missing from there.
1806 Added the handling of the KICK notify to the Irssi SILC client
1807 as it was missing. Added "you have been kicked" message to
1808 Irssi SILC client's message modules formats.
1810 Added the handing of the KILL notify to the Irssi SILC client
1811 as it was missing. Added the kill message module formats
1814 The affected file is irssi/src/silc/core/silc-channels.c.
1816 * The router did not save the channel mode the server announced.
1817 Affected file silcd/packet_receive.c.
1819 * Fixed a possible crash in INFO command in server. If the
1820 server did not provide the server info it crashed. Affected
1821 file silcd/command.c.
1823 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Fixed the GETKEY command in the server to check also the
1826 global list. Otherwise the GETKEY would not work correctly
1827 in normal SILC server. Affected file silcd/command.c.
1829 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Fixed GETKEY crash, it crashed if the command did not succseed.
1833 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1836 is now real and not just an macro interface to GMP.
1838 Removed the entire GMP from the source tree and imported new
1839 NSS MPI library instead. Reason for removing GMP is that it is
1840 extremely large and compiles extremely slow. The NSS MPI
1841 is only a few files and compiles in less than 10 seconds.
1842 The speed is also about the same as GMP. The MPI is imported
1843 to lib/silcmath/mpi.
1845 If the system has GMP installed we will still use the GMP.
1846 If it is not then the NSS MPI will be compiled.
1848 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Merged a long nickname (127 characters long) crash bugfix from
1851 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1853 * Merged a freed memory reference bugfix from Irssi CVS tree.
1854 Affected file irssi/src/core/commands.c.
1856 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Added the server's public key sving and verification to the
1859 server when performing the SKE. This was missing and the
1860 remote server's (or router's) public key was accepted without
1861 checking whether we have it previously or trust it at all.
1862 Affected file silcd/protocol.c.
1864 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1866 * Check in the silc_server_timeout_remote if protocol is active
1867 and make sure that the protocol's final callback is called so
1868 that all memory if freed. Affected file silcd/server.c.
1870 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * silc_server_whois_send_reply crashed the server if the nickname
1873 was 127 characters long. Affected file silcd/command.c.
1875 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Added sanity check to the silc_server_new_client. If the hostname
1878 is provided inside username then check that the provided hostname
1879 really is the same as the resolved one. If the hostname was not
1880 resolved then check it from the public key. Affected file is
1881 silcd/packet_receive.c.
1883 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1884 if the server disconnected us and the connection is not valid
1885 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1887 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1888 the library to the lib/silcutil/silcutil.[ch].
1890 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1892 * Close log file after open. Affected file
1893 lib/silcutil/silclog.c.
1895 * Check whether sock == NULL in silc_client_send_packet and return
1896 if it is. Affected file lib/silcclient/silcclient.c.
1898 * Check rec->entry == NULL in the Irssi SILC Client before
1899 sending the channel message. Affecte file is
1900 irssi/src/silc/core/silc-servers.c.
1902 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1904 * Merged a splitted window bugfix from Irssi CVS tree. The
1905 affected file is irssi/src/fe-text/textbuffer-view.c.
1907 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1908 It did not print nickname.
1910 * Improved the distributions system a bit.
1912 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1914 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1915 irssi/src/fe-text/gui-window.c.
1917 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1918 to in-active server. The affected file is
1919 irssi/src/silc/core/client_ops.c.
1921 * Resolve the client in USERS command reply if the entry does
1922 not have username resolved. The affected file is
1923 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1924 command to WHOIS command to really resolve stuff. The USERS
1925 is not used any more in any critical section so WHOIS can
1926 be used even though it might be slower than IDENTIFY.
1928 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1931 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Changed the protocol API a bit more consistent in the
1934 lib/silccore/silcprotocol.[ch].
1936 * Changed the following headers to ROBODoc format:
1938 lib/silccore/silcpayload.h
1939 lib/silccore/silcprotocol.h
1940 lib/silccore/silcsockconn.h
1942 All core library headers are now formatted.
1944 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Fixed a bug in Irssi SILC client; do not show that you are
1947 server/router operator if you really are not. Affected file is
1948 irssi/src/silc/core/client_ops.c.
1950 * Renamed silc_command_free_payload to silc_command_payload_free.
1951 Affected file lib/silccore/silccommand.h
1953 * Added silcmath.h to include the prototoypes of various routines
1954 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1957 * Changed the following headers to ROBODoc format:
1959 lib/silccore/silcchannel.h
1960 lib/silccore/silccommand.h
1961 lib/silccore/silcid.h
1962 lib/silccore/silcidcache.h
1963 lib/silccore/silcmode.h
1964 lib/silccore/silcnotify.h
1965 lib/silccore/silcpacket.h
1966 lib/silcmath/silcmath.h
1968 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1970 * Added checking to the server code not to start the server if
1971 ciphers and stuff are not configured properly. Affected files
1972 silcd/serverconfig.[h] and silcd/server.c.
1974 * Changed the layout of the header files of the public interfaces
1975 in the SILC libraries. The new layout supports ROBODoc
1976 documentation tool (and some others) so that it is easy to create
1977 a library reference manual. All the other headers and source
1978 code must still follow the CodingStyle document. Also source
1979 code must not include these ROBODoc stuffs, only the headers.
1980 Furthermore, all public interface headers must now be named
1981 by using `silc' prefix, example: silcapi.h, silccipher.h.
1982 Some files were renamed due to this. All the other headers
1983 must not be used as public interfaces. I will update the
1984 CodingStyle document later. Changed following headers, so far:
1986 lib/silcclient/silcapi.h
1987 lib/silccore/silcauth.h
1988 lib/silccore/silcprivate.h
1989 lib/silccrypt/silcdh.h
1991 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Removed silc_client_packet_send_flush from the client library
1996 as it is not needed. Affected file lib/silcclient/client.[ch].
1998 * Added printing of message of unresolved authentication method
1999 to the Irssi SILC client. Added it to the module formats.
2000 Removed the same message from the client library.
2002 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2004 * Added new distribution feature, DISTLABEL. Every distribution
2005 can define own preprocessor label that can be used in the
2006 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2007 file distributions, acconfig.h.pre and prepare.
2009 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Added Makefile.defines_int to include the actual definitions
2012 for Makefile.defines.in. Tested the new distribution system,
2013 created distributions and tested installation.
2015 * Added AWAY message printing to the Irssi SILC client. Added
2016 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2018 * Added SCONNECT command to call the SILC's CONNECT command.
2019 Cannot use CONNECT directly since Irssi uses that internally.
2020 Affected file irssi/src/silc/core/silc-servers.c.
2022 Added ACTION local command. It is same as ME command but takes
2023 the channel as mandatory argument.
2025 Rewrote some of the Irssi's help files to suite for SILC
2028 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Added Makefile.defines[.in] that should for now on be included
2031 in all Makefile.am file in the source tree. That file includes
2032 all common compilation definitions for SILC source tree.
2034 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Minor changes to the ./prepare script to change the package
2037 name according the distribution name to the configure.in.
2039 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Created new distribution system. Added file `distributions'
2042 that defines all the distributions that can be created out of
2043 the SILC source tree. The ./prepare script now reads that
2044 file to determine how to prepare the distributions. The
2045 first argument to the ./prepare is the name of the distribution
2046 and second is the version of the distribution. If given
2047 without arguments it creates the default (toolkit) distribution
2048 with the default version (defined in ./prepare).
2050 All Makefile.am files that are subject to the distributions
2051 are now named as Makefile.am.pre. These are ./Makefile.am
2052 and lib/Makefile.am. Others may be changed later.
2054 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Added invite list, ban list, some key management and connection
2057 error message printing to module formats in the Irssi SILC client.
2059 * Added new silc_client_set_away_message to set the away message
2060 that is back to the person who sent private message. The
2061 affected file lib/silcclient/silcapi.h and the
2062 lib/silcclient/client_prvmsg.c.
2064 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Fixed the private message sending in the Irssi SILC client,
2067 added local command KEY to the Irssi SILC client.
2069 Added key management and key agreement message formats to the
2070 irssi/src/fe-common/silc/module-formats.[ch].
2072 Added USERS (alias WHO) printing, server/router operator
2073 indication and LIST command printing to the module formats.
2075 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Fixed channel joining notify handling, cumode notify handling
2078 from Irssi SILC client.
2080 * Added SILC specific module-formats to the Irssi SILC client so
2081 that SILC specific message hilighting, colors etc is possible.
2082 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2084 Added channel mode, channel user mode, actions, notices,
2085 whois and whowas printing to the the module-formats.c.
2087 * Fixed a bug in channel deletion in the server. The channel
2088 is not left to the cache even if the channel founder auth mode
2089 is set when there are no users anymore on the channel. Affected
2090 file silcd/server.c.
2092 * The silc_net_localhost now resolves the entire hostname including
2093 the domain name. Affected file lib/silcutil/silcnet.c.
2095 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Changed the ask_passphrase client operation to be ascynchronous.
2098 It has now a completion callback and a context that the
2099 application must call after it has got the passphrase from
2100 the user. Affected files lib/silcclient/silcapi.h,
2101 lib/silcclient/protocol.c, lib/silcclient/command.c and
2104 Added SilcAskPassphrase callback that the application calls
2105 to deliver the passphrase to the library.
2107 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2108 The public key verification and especially a certificate
2109 verification is asynchronous procedure.
2111 Added new SILC_SKE_STATUS_PENDING status to indicate the
2112 request is pending and a callback will be called to finalize
2115 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2116 indicate that remote end did not send its public key (or
2117 certificate), even though we require it. Added check for this
2118 condition in the SKE. This was a security bug, now fixed.
2120 Defined new SilcSKEVerifyCbCompletion callback that is called
2121 when the verification process is completed.
2123 The affected files lib/silcske/silcske_status.h and
2124 lib/silcske/silcske.[ch].
2126 * Changed the verify_public_key client operation to be async
2127 as well. Defined SilcVerifyPublicKey callback that is used to
2128 indicate the success of the public key verification process.
2130 Changed the server and client to use the new async client
2133 * Changed the Irssi SILC client's internal scheduler to be called
2134 twice as many times as it used to be. As a result the client
2135 should be a bit faster now. Affected file is
2136 irssi/src/silc/core/silc-core.c.
2138 * Added support to Irssi SILC client of asynchronous public key
2139 verification and passphrase inquiry. Affected file is
2140 irssi/src/silc/core/silc-core.c.
2142 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Do not say "You have left channel %s" in client library.
2145 Moved it to the application. Affected files are
2146 lib/silcclient/command.c and silc/client_ops.c.
2148 * Fixed silc_client_get_clients. Command context was not
2149 duplicated and was freed memory in the callback. Affected
2150 file lib/silcclient/idlist.c.
2152 * Do not say "you are now talking..." on JOIN command in the
2153 client library. The appliation must handle it.
2155 * Do not say ".. changed topic to" in command reply in the
2156 client libary. The application must handle it.
2158 * Fixed TOPIC command sending in the client library.
2160 * Fixed a memory leak in silc_client_command_free in the file
2161 lib/silcclient/command.c.
2163 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Imported a modified version of Irssi client to the source tree.
2166 The Irssi will be used to create a new client called
2167 Irssi SILC. Imported to irssi/.
2169 Added silc_core_init_finish function to the Irssi. Affected
2170 file irssi/configure.in.
2172 A lot changes in the Makefile.ams around the irssi tree.
2174 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Do not rehash if the new size is same as the old size of the
2177 hash table, in the silc_hash_table_rehash*. The affected file
2178 lib/silcutil/silchashtable.c.
2180 * Replaced hash_table_del_by_context calls from the server
2181 (when channel->user_list and client->channels) to the
2182 hash_table_del as it is sufficient and faster.
2184 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Added silc_hash_table_list, silc_hash_table_get and the
2187 SilcHashTableList structure to provide an alternative way to
2188 traverse the hash table. The affected files are
2189 lib/silcutil/silchashtable.[ch].
2191 * Changed the server's idlist routines to use the hash table
2192 routines to optimize the code.
2194 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * Replaced the client entry's `channel' list and channel entry's
2197 `user_list' list to hash tables for optimized lookup. Changed
2198 the code to use the hash table interface around the code.
2199 Affected file lib/silcd/idlist.[ch].
2201 * Added `auto_rehash' boolean argument to the function
2202 silc_hash_table_alloc to indicate whether the hash table should
2203 auto-rehash when it thinks is appropriate time. It will
2204 increase the hash table size if the there is twice as much
2205 entries in the table than the size of the table, and will
2206 decrease the size if there are twice as less entries than
2207 the size of the table.
2209 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2213 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * silc_idcache_purge_by_context deletes the entry now by context
2216 as it is supposed to do. Affected file lib/silccore/idcache.c.
2218 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2219 client is not anymore valid (WHOWAS givens the info) and not
2220 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2222 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Removed the `data' and `data_len' arguments from the ID Cache
2225 interfaces and added `name' argument. ID Cache does not handle
2226 anymore the binary data only a names associated with given ID.
2228 * When hashing a Client ID with silc_hash_id the entire ID is
2229 not hashed anymore, instead only the hash of the Client ID is
2230 hashed. This way we can access the Client ID from the cache
2231 with Client ID but with the hash of the ID (which is a hash of
2232 the nickname) as well without any difference in performance.
2234 Added also silc_idcache_find_by_id_one_ext to do one on one
2235 searching when we have the actual ID. Added also function
2236 silc_hash_client_id_compare. The affected files are
2237 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2239 * When hashing the name associated with a ID it is always done
2240 in lowercase. This way we can access the cache without worrying
2241 about case-sensitivity, even though, for example nicknames are
2244 * Fixed a bug in server with channel message sending. It put
2245 wrong ID type as destination ID. The affected file
2246 silcd/packet_send.c.
2248 * silc_idcache_del_by_context now deletes from all hash tables
2249 by context. Affected file lib/silccore/idcache.c.
2251 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Changed the client library to use the new ID Cache interface.
2254 Changes around the source tree.
2256 * Added silc_hash_table_rehash_ext to rehash with specific
2257 hash function. Affected file lib/silcutil/silchashtable.[ch].
2259 * Added silc_hash_string_compare to compare two strings in the
2260 hash table. Affected file lib/silcutil/silcutil.[ch].
2262 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Added new function silc_idcache_del_by_context into the
2265 lib/silccore/idcache.[ch].
2267 * Changed the server's ID list routines to use the new ID Cache
2268 interface. Changes around the source tree.
2270 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2272 * Added silc_hash_table_del[_by_context]_ext functions in to the
2273 lib/silcutil/silchashtable.[ch].
2275 Removed silc_hash_table_find_all* routines and added new
2276 silc_hash_table_find_foreach to replace them.
2278 Added silc_hash_table_replace_ext function as extended
2279 replacing function. Separated the simple hash table interface
2280 from the extended hash table interface in the file
2281 lib/silcutil/silchashtable.h.
2283 * Fixed minor bugs and changed it to use some of the new
2284 hash table functions in lib/silccore/idcache.c
2286 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Added new function silc_hash_table_find_all to return all keys
2289 in the hash table by the specified key. As the hash table is
2290 collision resistant it also makes it possible to have several
2291 duplicate keys in the hash table. This function may be used to
2292 find all of the keys from the hash.
2294 Added user_context arguments to the SilcHashFunction,
2295 SilcHashCompare and SilcHashDestructor to deliver user specified
2298 Added new fuctions silc_hash_table_find[_all]_ext to do
2299 extended lookup with specified hash and compare functions and
2300 specified user contexts.
2302 Added new function silc_hash_table_add_ext to add the key
2303 with specified hash function and user context.
2305 Added new function silc_hash_table_foreach to traverse all
2306 entrys in the hash table. Added SilcHashForeach callback
2309 Added new function silc_hash_table_del_by_context to delete
2310 the entry only if the context associated with the key matches.
2312 Affected files are lib/silcutil/silchashtable.[ch].
2314 * Removed silc_hash_[server/client/channel]_id and added just
2315 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2316 silc_hash_id_compare to compare two ID's using as the hash table
2317 comparison function. Added also silc_hash_data to hash
2318 binary data and silc_hash_data_compare to compare it.
2320 * Removed silc_idlist_find_client_by_hash as it is not needed
2321 anymore. Affected file silcd/idlist.[ch].
2323 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2324 to use internally the SilcHashTable. The new ID Cache is a lot
2325 faster than the old one. Some of the ID Cache interface was also
2326 rewritten and obsolete and stupid functions were removed.
2328 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Added entry_count field to the SilcHashTable to keep the number
2331 of the entries in the table. Implemented the function
2332 silc_hash_table_rehash. Added new function
2333 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2335 Fixed a minor bug in silc_hash_table_free.
2337 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2338 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2339 into the lib/silcutil/silcutil.[ch].
2341 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * Implemented a collision resistant hash table into the
2344 lib/silcutil/silchashtable[ch]. See the header and the source
2345 for the SilcHashTable API.
2347 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Merged dotconf version 1.0.2 into lib/dotconf.
2351 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Do not compile anything in lib/silcsim/* if the SIM support
2354 is not enabled. The tree should now compile without problems
2357 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Compiled the SILC under cygwin. Compiled and tested briefly
2360 without problems. More tests needed. The SIMs didn't compile
2363 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2365 * Fixed possible crash in silc_get_username in the
2366 lib/silcutil/silcutil.c.
2368 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Fixed a va_arg in silc/client_ops.c.
2372 * Oops, RC5 routines were named AES and caused some problems
2373 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2375 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Added new SilcIDIP structure into the lib/silccore/id.h and
2378 replaced the old `ip' fields from all SILC ID's to that type.
2379 This is a step towards IPv6 support.
2381 The silc_id_get_len takes now the ID as an extra argument.
2382 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2383 both IPv4 and IPv6 based ID's.
2385 The affected files are lib/silccore/id.[ch] and other files
2386 around the tree using these routines.
2388 * Removed the ID length arguments in server from various
2389 silc_server_send_notify_* routines -> they are not needed
2392 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Fixed memory leak in silc_encode_pem_file in the file
2395 lib/silcutil/silcutil.c.
2397 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Check minor version as well in the SKE. Affected files are
2400 silcd/protocol.c and lib/silcclient/protocol.c.
2402 * Added --identifier option to the server so that an identifier
2403 can be when creating the public key for the server. Affected
2404 file is silcd/silcd.c.
2406 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2407 lib/silccrypt/silcpkcs.c.
2409 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Register default ciphers and stuff when using -C option with
2412 the server. Affected file sildc/silcd.c.
2414 * Put back the servers public key filename format, it is better
2415 than the new one. For now, the client keys are saved with the
2416 new filename format. The affected file silc/client_ops.c.
2418 * Implemented the Cipher API for the rest of the ciphers that
2419 did not implement it or implemented it the wrong way.
2421 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Register default ciphers and stuff when using the -S option
2424 in the client. Affected file silc/silc.c. Same also when
2425 creating new key pair with -C option.
2427 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Fixed the silc_verify_public_key client operation function to
2430 save the public keys differently. The fingerprint is now
2431 used as filename and not the hostname. This way also the
2432 client keys are saved uniquely and not with hostnames. The
2433 affected file is silc/client_ops.c.
2435 * Trimmed the silc_hash_fingerprint function to remove extra
2436 whitespaces from the end of the fingerprint. The affected
2437 file is lib/silccrypt/silchash.c.
2441 * Added silc_cipher_register_default function to register all
2442 default ciphers. It can be used when configuration files
2443 does not exist and the application does not want any specific
2444 ciphers in any specific order.
2446 The SilcDList is now used as silc_cipher_list dynamically
2447 allocated cipher list. Removed the static list all together
2448 and now all ciphers must be allocated to the dynamic list.
2449 The silc_cipher_alloc routine was changed to check only the
2452 All silc_cipher_* routines that used to return int returns
2455 The affected files lib/silccrypt/silccrypt.[ch].
2457 * The same thing was done to silc_hash_* as for silc_cipher_*
2458 routines. Affected files lib/silccrypt/silchash.[ch].
2460 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2461 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2462 Added also silc_pkcs_[un]register[_default] functions.
2463 Removed the data_context from the PKCS API.
2465 * Added silc_hmac_register_default function to register default
2466 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2467 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2468 to unregister all hmacs at once.
2470 * Register the default ciphers, hash functions, PKCSs and HMACs
2471 if client's configuration file does not exist. The affected
2474 * The client did not load the hash functions from the SIM
2475 modules at all. Added support for this. Affected file is
2476 silc/clientconfig.c.
2478 * When decoding public key with silc_pkcs_public_key_decode, check
2479 the supported algorithm only if PKCS are registered. Affected
2480 file lib/silccrypt/silcpkcs.c. The same was done with the
2481 silc_pkcs_private_key_decode.
2483 * Fixed the SILC List routines to keep the list always in order.
2484 It used to change the list's order when traversing the list but
2485 not it preserves the order. Affected file lib/trq/silclist.h.
2487 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * Added the client library to use the SilcSocketConnection's
2490 reference counter (by silc_socket_dup) to prevent the bug that
2491 the socket object may be freed underneath async operation.
2493 * The name resolv library checking fixes in the configure.in.pre.
2496 * Created new version of the protocol drafts for future
2497 development. The -03 drafts are the ones that will be changed
2498 in the trunk now and the -02 will remain as they are.
2500 * Send list of CUMODE notifys to the router when announcing
2501 the channel users to the router. Affected file silcd/server.c.
2502 If the router receiving channel founder CUMODE for a channel
2503 that already has channel founder it will send CUMODE notify
2504 to the sender to remove the channel founder rights from the
2505 announced client. Affected file silcd/packet_receive.c.
2507 * The CUMODE notify may now use Server ID as well as the entity
2508 who changes the mode. Updated protocool specs.
2510 * Updated INSTALL and README files.
2512 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * New web pages in the http://silc.pspt.fi. The pages was
2519 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Implemented the [DenyConnectin] config section in the server.
2522 Added silc_server_config_denied_conn to check whether incoming
2523 connection is denied. Affected file silcd/serverconfig.[ch].
2525 * Do not check the ports when checking the incoming configuration
2526 data if the port is 0, meaning any. Affected file is
2527 silcd/serverconfig.c.
2529 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Fixed buffer overflow in silc_string_compare in the file
2532 lib/silcutil/silcutil.c.
2534 * Fixed double free in silc_server_command_leave in the file
2537 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Fixed the version checking in the server. Affected file is
2542 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Fixed the configuration data fetching when accepting new
2545 connections in the server. Affected file silcd/server.c.
2547 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Added `sender_entry' argument to the function
2550 silc_server_packet_relay_to_channel so that we can check
2551 whether some destination actually belongs to the same route
2552 the sender belongs (ie, we must not resend the packet to the
2553 sender). Affected file silcd/packet_send.[ch].
2555 * Added `servername' field to the SilcClientEntry in the server
2556 to hold the name of the server where client is from. Affected
2557 file is silcd/idlist.h.
2559 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2561 * Moved the channel message encrypting in the router betwen
2562 router connections from silc_server_channel_message to the
2563 silc_server_packet_relay_to_channel since we want to check
2564 whether we have anybody channel before encrypting anything.
2565 Affected files silcd/packet_[receive/send].c.
2567 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Fixed the [AdminConnection] server config section to support
2570 multiple entries. Affected file silcd/serverconfig.c.
2572 * Added support into the server to check the validity of the
2573 incoming connection before executing any KE or authentication
2576 * The connection configuration is now saved to the KE and
2577 connection auth protocol contexts and not fetched anymore in
2578 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2580 * The local hosts listenning address and port is also resolved
2581 now when starting the server. We want to have the socket object
2582 to include the real address and port for the listener. Added
2583 new function silc_net_check_local_by_sock into the files
2584 lib/silcutil/silcnet.[ch].
2586 * Fixed a broadcast bug in server -> do not broadcast if we
2589 * Fixed a routing bug. Do not route broadcast packets ever.
2590 Broadcast packets must be processed always and not routed since
2591 they may be destined to some other host than yourself and thus
2592 would get routed without no good reason. Affected file is
2595 * Added function silc_server_config_is_primary_route to check
2596 whether primary router connection has been configured (a router
2597 configuration that we are initiating). If there is not, we
2598 will assume that there is only two routers in the SILC network
2599 and we will use the incoming router connection as our primary
2600 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2602 * Changed the order of the broadcasting. Broadcast _after_ the
2603 packet has been processed not before. Affected file is
2606 * Fixed a [ClientConnection] parsing bug. The port was never
2607 parsed correctly thus resulting to port 0. Affected file
2608 silcd/serverconfig.c.
2610 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2611 argument and did not set the broadcast packet flag. Affected
2612 file silcd/packet_send.c. Fixed same bug in the function
2613 silc_server_send_notify as well.
2615 * If we receive NEW_ID packet for our own ID in the server, ignore
2618 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Removed the nickname from the Private Message Payload.
2623 Updated the code and the protocol specs.
2625 * Updated protocol specs for submitting to the IETF.
2627 * Tweaked the Random Number Generator a bit. Affected file
2628 lib/silccrypt/silcrng.c. Exported a new function
2629 silc_rng_[global]_add_noise which can be used to add more
2632 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Do not parse packets with different timeout when protocol
2635 is active -> may cause problem with rekey. Affected file
2638 * When server receives signoff notify it must not create
2639 new channel key if the client is on any channels since the
2640 sender of the signoff notify will create it.
2642 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added printing of error messages during SKE protocol from the
2645 failure packet sent by server during SKE. Affected file
2648 * Removed the client's failure_callback handling with timeout
2649 and handle it immediately when received.
2651 * The SKE library returned wrong type in SUCCESS and FAILURE
2652 packets. They must be 32 bit MSB not 16 bit MSB.
2654 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2656 * Ok, rewrote the logic of the re-key and now it seems to work.
2657 I tested it on high traffic with frequent re-keys without
2658 problems. Added hmac_receive (and renamed hmac to hmac_send)
2659 in SilcClientConnection in lib/silcclient/client.h and
2660 in SilcIDListData in silcd/idlist.h. Also, removed the
2661 SilcPacketParserContext's cipher and hmac fields as they are
2662 not needed anymore and actually caused some problems when
2663 the ciphers and hmac's changed underneath the packet parser.
2665 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * If re-key protocol is active then process the incoming packets
2668 synchronously since we must assure that icoming packets encrypted
2669 with the old key is processed before the new keys is set to
2670 use. This is true other packets than for REKEY packets.
2671 Affected file silcd/server.c. The same was done to client library
2672 as well, affected file lib/silcclient/client.c.
2674 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * Fixed bug in client and server to accept the force send if
2677 the packet is send from silc_[server/client]_packet_process
2678 function. Otherwise the packets are never delivered, oops.
2680 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Disable force sending of packets when REKEY protocol is active.
2683 We must assure that no packet is sent directly when rekey is
2684 performed. All packets must be sent through packet queue.
2685 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2686 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2687 function is silc_[server/client]_packet_send_real to check
2690 * Replaced the SIM paths from example config files to
2691 /usr/local/modules. Also, make install creates now
2692 /usr/local/silc/logs directory to hold all the SILC server
2695 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Made the configure.in.pre work on Solaris. Patch by salo.
2699 * Made all ciphers compatible with non-x86 machines. Defined
2700 CBC mode macros into lib/silccrypt/ciphers_def.h.
2702 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2706 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * When MAC computation fails the silc_packet_decrypt returned 0
2709 even though it was supposed to return -1. Fixed this. The
2710 affected file is lib/silccore/silcpacket.c.
2712 * Do not replace the config files in /etc/silc (in make install)
2713 if they already exist. Affected file ./Makefile.am.
2715 * Do not send re-key packets immediately but through packet queue.
2716 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2718 * Changed silc_net_check_host_by_sock to return FALSE if the
2719 IP/DNS could not be resolved. Though, it returns the IP address
2720 now even if it could not resolve it (but returns also FALSE).
2721 Affected file lib/silcutil/silcnet.[ch].
2723 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Added silc_pkcs_decode_identifier to decode the public key's
2726 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2727 Added also silc_pkcs_free_identifier. Added also new context
2728 SilcPublicKeyIdentifier.
2730 * Added -S option to the silc client. It is used to dump the
2731 contents of the specified public key file.
2733 * Changed the PKCS api to return the public key length when
2734 setting the public key.
2736 * Fixed a fatal bug in the public and private key file loading.
2737 Affected file lib/silccrypt/silcpkcs.c.
2739 * Execute the packet parsing for client with zero (0) timeout
2740 if the protocol is active. Affected file silcd/server.c.
2742 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Made the key generation options to the silcd program. Added
2745 -C option, equivalent to client's option.
2747 * Added new [ServerKeys] config section to the server. It
2748 configures the server's public and private key.
2750 * Defined generic Public Key Payload into the protocol
2751 specification to send specific type of public keys and
2754 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2755 public key or certificate.
2757 * Implemented the GETKEY command to the server and to the
2758 client library and on user interface.
2760 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Made preliminary `make install' work.
2764 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Added SilcServerRekey context into silcd/idlist.h.
2768 * Added the PFS support as defined in the specification to the
2769 SKE protocol. Affected files lib/silcske/*.c.
2771 * Added `ske_group' field to the SilcServerRekey context to hold
2772 the number of the SKE group that is used with PFS in re-key.
2773 Affected file silcd/idlist.h.
2775 * Added PFS re-key support to the server. Affected file is
2778 * Added silc_protocol_cancel to cancel execution of the next
2779 state of the protocol. Affected file is
2780 lib/silccore/silcprotocol.[ch].
2782 * Added the re-key support with and without PFS to the client
2783 library. Re-key is performed once in an hour, by default.
2785 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2786 Added silc_client_rekey_callback and silc_client_rekey_final.
2787 Affected files are lib/silcclient/protocol.[ch] and
2788 lib/silcclient/client.[ch].
2790 * Removed the `hmac_key' and `hmac_key_len' fields from the
2791 SilcClientConnection structure; not needed. Affected file is
2792 lib/silcclient/client.h.
2796 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Do not ask whether user wants to use the negotiated private key
2799 for private messages, just use it. Affected file is
2800 silc/local_command.c.
2802 * Added `send_enc_key' and `enc_key_len' fields to the
2803 SilcIDListData structure since they are needed in the re-key
2804 phase. Affected file is silcd/idlist.[ch].
2806 * Implemented the simple re-key protocol into the server.
2807 Affected files silcd/server.c and silcd/protocol.[ch]. The
2808 re-key will be performed once in an hour, by default.
2810 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2811 Added silc_server_rekey, silc_server_rekey_callback and
2812 silc_server_rekey_final.
2814 * Removed Tunneled flag from the protocol. Updated the code
2815 and the specifications.
2817 * Adde `pfs' field to the SilcIDListData to indicate whether
2818 the PFS is to be performed in the re-key. Affected file is
2821 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2824 int64 of at least the xintXX size. If void * is less that 4
2825 bytes uint32 * will be used. Defined bool as boolean.
2827 * Changed _ALL_ unsigned long and unsigned int to uint32,
2828 unsgined short to uint16 in the source tree.
2830 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2831 not handle clients that has entry->data.registered == FALSE.
2832 They are not in the network anymore. Affected file is
2835 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Implemented the sending of the SERVER_SIGNOFF notify in the
2838 server. Affected file is silcd/server.c.
2840 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2841 Added also silc_notify_payload_encode_args into the
2842 lib/silccore/silcnotify.[ch].
2844 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2845 Affected file silcd/packet_receive.c.
2847 * Implemented the SERVER_SIGNOFF notify handling in the client
2848 library. Affected file lib/silcclient/client_notify.c. Also,
2849 implemnted the printing of the SERVER_SIGNOFF info to the
2850 application. Affected file silc/client_ops.c.
2852 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2853 if the deleting was successful. Affected file silcd/idlist.[ch].
2855 * Added support for public key authentication in the connection
2856 authentication protocol in the client library. Affected file
2857 lib/silcclient/protocol.c.
2859 * Changed the server's silc_idlist_get_clients_by_* interface
2860 to support already allocated array so that new entries may be
2861 added to pre-allocated array. Affected file silcd/idlist.[ch].
2862 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2863 and command replies.
2865 * All command reply functions in the server now calls the
2866 pending command callback even if error occured. This way the
2867 error will be delivered to the client as well. Affected files
2868 silcd/command.c and silcd/command_reply.c.
2870 * Fixed INFO command to return local server's info if no server
2871 was provided. Affected file lib/silcclient/command.c.
2873 * Removed RESTART command for good. Updated the code and the
2876 * Rewrote parts of the task system. It is a bit simpler now.
2877 Removed unsued task priorities. The affected files are
2878 lib/silcutil/silctask.[ch].
2880 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2882 * Moved the USERS printing from the library to the application.
2883 Affected files lib/silcclient/command.c and silc/client_ops.c.
2885 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Added channel key re-key support. The re-key is perfomed
2890 only by the router and is done once in an hour. Added `rekey'
2891 field to the SilcChannelEntry in the server. Affected files
2892 silcd/server.c and silcd/idlist.h.
2894 * Added silc_task_unregister_by_context into the file
2895 lib/silcutil/silctask.[ch].
2897 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Added SILC_UMODE_GONE mode to indicate when the client is not
2900 present in the SILC network. Added also support to the local
2901 command AWAY that will set this mode. Added support of showing
2902 "xxx is gone" in WHOIS command. The USERS command shows the
2903 gone status as well.
2905 * Fixed setting server and router operator privileges in the
2906 server's UMODE command. Affected file silcd/command.c.
2908 * Merged the SKE KE1 and KE2 payloads into one payload. The
2909 new KE payload is equivalent to the old KE2 payload.
2911 Cleaned up the SKE Start Payload parsing. It now uses the
2912 simple buffer unformatting to do the parsing. A lot faster
2915 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2916 to the SKE that is used to indicate whether both of the SKE
2917 parties should perform authentication. By default only the
2918 responder performs authentication. By setting this flag also
2919 the initiator must do authentication. By default it is unset
2920 since in normal SKE case, client to server connection, only
2921 the responder should do authentication. When doing SKE between
2922 two clients both should perform authentication. Updated the
2923 code and the protocol specs.
2925 * A little fix to IDENTIFY command in the server. Search the
2926 client first by hash not nickname. Affected file is
2929 * Fixed the silc_client_close_connection to support closing
2930 the client to client connections wihtout deleting too much
2931 data. Affected file lib/silcclient/client.c.
2933 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2934 are received if protocol used to be active but is not anymore
2935 the application would crash due to NULL pointer dereference.
2936 Affected files silcd/server.c and lib/silcclient/client.c.
2938 * Added `hash' field to the SilcClientConnection to include
2939 the hash function negotiated in the SKE protocol.
2941 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2942 to set the channel founder authentication data. A client can
2943 claim the founder rights later by providing the authentication
2944 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2945 This way the channel founder can regain the channel founder
2946 privileges even it is left the channel. This works only on
2947 local server and the client must be connected to the same
2948 server to be able to regain the founder rights. Updated the
2949 protocol specs accordingly.
2951 Added support to the CMODE command in the client to set the
2952 founder auth data. Read the README to see how to set it.
2954 Added support to the CUMODE command to claim the founder
2955 rights. Read the README to see how to do it.
2957 Added support for the founder authentication to the Channel
2958 Entry in the server. Affected file silcd/idlist.h.
2960 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2961 server's CMODE command. Affected file silcd/command.c.
2963 * Added the following new functions into lib/silccore/silcauth.[ch]:
2964 silc_auth_get_method and silc_auth_get_data.
2966 * The server now saves the remote hosts public key to the
2967 SilcIDListData pointer. Affected file silcd/protocol.c.
2969 * The normal server now does not remove the channel entry from
2970 the cache if the founder authentication data is set. It used
2971 to remove it if the founder was the last one on the channel on
2972 the server and left the channel. The auth data is saved and
2973 if the channel is re-joined later the old entry is used with
2974 the old auth data. Affected files silcd/command_reply.c and
2977 * Removed the `pkcs' field from the SilcIDListData structure
2978 in the server; it is not used. Affected file silcd/idlist.h.
2980 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Fixed packet processing on slow links. Partial packets were
2983 never re-processed because the incoming data buffer was cleared
2984 by the application. Application must not directly clear the
2985 sock->inbuf, the packet processing routines handle it. Fixed
2986 this in client library and in server.
2988 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2990 * Fixed the WHOIS and IDENTIFY send reply function to really
2991 check whether to send list or just one entry. Affected file
2994 * Cleaned up the LEAVE command's channel key distribution. The
2995 affected file silcd/command.c.
2997 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2998 can enforce the channel mode as well. In that case the ID
2999 includes the ID of the server. The code now enforces the
3000 mode change if the router have different mode than the server.
3002 * The notify client operation with CMODE_CHANGE notify can now
3003 return NULL client_entry pointer if the CMODE was not changed
3004 by client. Application must check for this.
3006 * Added <Server ID> argument to INFO command to support server
3007 info fetching by Server ID.
3009 * Added silc_server_announce_get_channel_users to get assembled
3010 packets of channel users of the specified channel. Affected
3011 file silcd/server.[ch].
3013 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3014 was freed underneath the ID Cache.
3016 * Re-announce clients when the server received CHANNEL_CHANGE
3017 notify from the router. Affected file silcd/packet_send.c.
3019 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3022 crashed since it did not handle the fact that there is no cipher
3023 called "3" and didn't check the error condition. Now fixed.
3025 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3026 flag. It can be used to send message requests.
3028 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Implemented the RESTART command in the client.
3032 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3033 notice type messages. Added notice printing to the user
3036 * The channel keys are not re-generated if the channel's mode
3037 is PRIVKEY, ie private key on the channel exists. Affected
3038 files silcd/server.c and silcd/command.c.
3040 * Fixed a little bug in channel message delivery when channel
3041 private keys are set in the server. Affected file is
3042 silcd/packet_send.c.
3044 * Changed the setting on channel->on_channel = TRUE from the
3045 silc_client_save_channel_key to the JOIN command reply. The
3046 key payload is not received if the private channel key is set.
3047 Affected file lib/silcclient/command_reply.c and the
3048 lib/silcclient/client_channel.c.
3050 * When the CMODE_CHANGE notify is sent and the channel private
3051 key mode is removed the channel key must be re-generated in
3052 other cells as well. Added this support for the router in the
3053 silcd/packet_receive.c.
3055 * Added new local command NOTICE to send notice message on
3056 channel. Affected file silc/local_command.[ch].
3058 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Added new local command ME to the client. It is used to send
3061 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3062 some action. Affected file silc/local_command.[ch].
3064 * Changed channel_message and private_message client operations
3065 to deliver the message flags to the application. Added also
3066 the `flags' arguments to the silc_client_send_channel_message
3067 and silc_client_send_private_message functions. Affected file
3070 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Redefined the Private Message Payload to support private message
3073 keys and to support the new private message flags. Updated
3074 the protocol specs. Flags makes it possible to have for example
3075 CTCP style messages.
3077 * Added new type SilcPrivateMessagePayload and defined an API
3078 for it in the lib/silcclient/silcprivate.[ch].
3080 * Tested private message private keys successfully. Tested the
3081 private message key set, unset and list commands with the new
3084 * Redefined the Channel Message Payload to include the channel
3085 message flags (equal with private message flags) to support
3086 for example CTCP style messages.
3088 * Defined some of the message (for channel and private message)
3089 flags. Updated the protocol specs and added the flags to the
3090 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3092 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Added SilcKeyAgreementStatus type to the key agreement routines
3095 to indicate the current status and error if one occured.
3096 The status types are defined in the lib/silcclient/silcapi.h.
3098 * Added new local command KEY that is used to set and unset private
3099 keys for channels, set and unset private keys for private messages
3100 with remote clients and to send key agreement requests and
3101 negotiate the key agreement protocol with remote client. The
3102 key agreement is supported only to negotiate private message keys,
3103 it currently cannot be used to negotiate private keys for channels,
3104 as it is not convenient for that purpose.
3106 * Fixed a minor pending callback setting bug in the function
3107 silc_client_get_client_by_id_resolve, now the function works.
3108 Affected file lib/silcclient/idlist.c.
3110 * Added function silc_net_get_local_port to get local bound
3111 port by socket. Added to lib/silcutil/silcnet.[ch].
3113 * Added `sockets' and `sockets_count' fields to the SilcClient
3114 object. They hold the sockets of the listenning sockets in
3115 the client. Listenning sockets may be for example the key
3116 agreement server. Affected file lib/silcclient/client.[ch].
3117 Added functions the silc_client_add_socket and the
3118 silc_client_del_socket. They are exported to the application
3121 * Added ~./silc/clientkeys to support other client's public keys.
3123 * Renamed verify_server_key client operation to verify_public_key
3124 and added one argument to indicate the type of the connection
3125 (server, client etc.).
3127 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Added silc_server_connection_auth_request to handle the
3130 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3131 silcd/packet_receive.[ch].
3133 * Added silc_server_send_connection_auth_request into the
3134 silcd/packet_send.c to send the connection auth request packet.
3136 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3139 * Fixed the public key authentication in responder side in the
3140 server. The `auth_data' pointer includes the SilcPublicKey
3141 not the path to the public key. Affected file silcd/protocol.c.
3143 * Implemented the public key authentication in the initiator side
3144 in the server. Affected file silcd/protocol.c.
3146 * Removed the [RedirectClient] config section from the server
3147 configuration. Is not needed and I don't want to implement it.
3149 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Cleaned up the CMODE command in the server. It now works
3152 correctly and supports all the modes defined in the protocol.
3153 Affected file is silcd/command.c.
3155 * Added `hmac_name' field to the SilcChannelEntry in the server
3156 to hold the default HMAC of the channel. It can be set when
3157 creating the channel (with JOIN command). Affected files
3160 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3161 type to indicate the change of the current cipher and hmac
3162 on the channel. Client can safely ignore the <cipher> argument
3163 (if it chooses to do so) since the CHANNEL_KEY packet will
3164 force the channel key change anyway. The <hmac> argument is
3165 important since the client is responsible of setting the new
3166 HMAC and the hmac key into use.
3168 * Fixed the CMODE command in the client library as well.
3170 * Tested CMODE command in router environment successfully.
3172 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Show the version of the remote client (or server) when connecting
3175 to the server. It is logged to the log file. Affected file
3176 is silcd/protocol.c.
3178 * Fixed the KILLED notify handling in the client library. The
3179 client must be removed from all channels when receiving the
3182 Also, do not remove the client entry when giving the KILL
3183 command but when the KILLED notify is received.
3185 * Removed silc_idlist_find_client_by_nickname from the server.
3186 Not needed anymore. Affected files silcd/idlist.[ch].
3188 * Implemented the CHANNEL_CHANGE notify type handling to the
3189 server. Affected file silcd/server.c.
3193 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Added silc_server_send_notify_invite to send the INVITE
3196 notify between routers.
3198 * Implemented the INVITE command correctly to the server.
3200 * Implemented the INVITE notify type handling in the server.
3202 * Implemented the INVITE command to the client library and on the
3205 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Added function silc_server_get_client_resolve to find the
3208 client entry by ID from all ID lists and then resolve it
3209 (using WHOIS) if it cannot be found. Affected file is
3212 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Implemented the BAN command to the client library.
3216 * The JOIN command in the server now checks the invite list
3219 * Changed the silc_command_reply_payload_encode_va and the
3220 silc_command_payload_encode_va to support that if argument is
3221 NULL it ignores and checks the next argument. Affected file
3222 lib/silccore/silccommand.c.
3224 * Added silc_server_send_notify_ban to send the BAN notify
3225 type between routers.
3227 * Chaned the silc_notify_payload_encode to support that if
3228 argument is NULL it ignores and checks the next argument.
3229 Affected file lib/silccore/silcnotify.c.
3231 * Tested ban lists in router environment successfully.
3233 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Implemented BAN command to the server, in silcd/command.[ch].
3237 * Removed the BAN and INVITE_LIST modes from the CMODE command
3240 * Added function silc_string_match to regex match two strings.
3241 Affected files lib/silcutil/silcutil.[ch].
3243 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Redefined parts of the SilcChannelEntry in the server to support
3246 the new ban and invite lists.
3248 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Redefined the INVITE command. The same command can be used to
3251 invite individuals to the channel but also to manage the invite
3252 list of the channel (to add to and remove from the invite list).
3253 Updated the protocol specs.
3255 * Added new command SILC_COMMAND_BAN that can be used to manage
3256 the ban list of the channel. Updated the protocol specs.
3258 * Removed the channel modes: the SILC_CMODE_BAN and the
3259 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3260 in the CMODE command. The equivalent features are now available
3261 using INVITE and BAN commands. Updated the protocol specs.
3263 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3264 in the network about change in the current ban list. The notify
3265 type is not used by the client.
3267 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3268 support the invite lists.
3270 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Added new function silc_string_regexify that converts string
3273 including wildcard characters into regex string that can
3274 be used by the GNU regex library. Added into the file
3275 lib/silcutil/silcutil.[ch].
3277 Added silc_string_regex_combine to combine to regex strings
3278 into one so that they can be used as one regex string by
3279 the GNU regex library. Added into the file
3280 lib/silcutil/silcutil.[ch].
3282 Added silc_string_regex_match to match two strings. It returns
3283 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3285 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Imported GNU regex to the soruce tree into lib/contrib.
3288 Fixed some compiler warning from the regex.c.
3290 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Fixed MOTD command in the server to work in router environment.
3294 * Fixed the MOTD command in the client library to support
3295 the server argument in the command.
3297 * Added `nickname_len' argument to the silc_idlist_add_client
3298 in the server, as the `nickname' argument may be binary data
3301 * Added silc_idlist_get_channels to return all channels from
3304 * Implemented LIST command to the server. Affected file is
3307 * Implemented the LIST command to the client library and on the
3310 * Added [<user count>] argument to the LIST command reply.
3311 With private channels the user count is not shown.
3313 * Updated TODO and README.
3315 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * The client entry's data.registered must be TRUE even with
3318 global client entry on global client list. The data.registered
3319 is used to check whether the client is anymore in the network,
3320 for example with WHOWAS command so it must be valid.
3322 * Fixed the WHOWAS command in the server. It now actually works
3323 in router environment. Added function into silcd/command_reply.c
3324 silc_server_command_reply_whowas_save.
3326 * Added silc_idlist_purge function to the silcd/idlist.c
3327 to periodically purge the ID Cache.
3329 * Fixed INFO command in the server. It works now in router
3330 environment. Added <server name> argument to the INFO command
3331 reply. Updated the protocol specs.
3333 * Fixed minor bug in silc_idcache_purge to not purge if the
3334 expire value is zero.
3336 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3337 they were buggy because of the WHOWAS information.
3339 * Fixed local command MSG to handle the async resolving of
3340 the remote client properly. It used to fail the first MSG.
3341 Affected file silc/local_command.c.
3343 * Added `data_len' field to SilcIDCache context.
3345 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Update TODO. Todo in commands in the server.
3349 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3351 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3352 used by routers as broadcast packet to inform other routers
3353 about the changed user mode.
3355 Implemented the notify handling in the server. Affected file is
3356 silcd/packet_receive.c. Added the function
3357 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3359 * Added new generic Channel Payload and deprecated the New Channel
3360 Payload. The New Channel Payload is now the generic Channel
3363 * Added new argument `mode' to the silc_server_send_new_channel
3364 as it is required in the Channel Payload now.
3366 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3367 and created a new and real SilChannelPayload to represent the
3368 new generic Channel Payload. Implemented the encode/decode
3369 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3371 * Added silc_server_get_client_channel_list to return the list
3372 of channels the client has joined for WHOIS command reply.
3373 Affected file silcd/server.[ch].
3375 * Implemented the channel list sending in the WHOIS command reply
3376 in server and in the client.
3378 Implemented the channel list displaying on the user interface
3379 as well. Affected file silc/client_ops.c.
3381 * Added silc_channel_payload_parse_list to parse list of Channel
3382 Payloads. It returns SilcDList list of SilcChannelPayloads.
3383 Client for example can use this function to parse the list of
3384 channels it receives in the WHOIS command reply. The caller
3385 must free the list by calling silc_channel_payload_list_free.
3386 Affected files lib/silccore/silcchannel.[ch].
3388 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Added one new argument <user mode> to the WHOIS command reply
3391 to return the mode of the user in SILC. Updated the protocol
3394 Implemented it to the server and client.
3396 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Fixed the mode printing on the user interface on joining.
3399 Affected file silc/client_ops.c.
3401 * Implemented the UMODE command and user modes in general to the
3402 client library and to the user interface.
3404 * Implemented the UMODE command to the server.
3406 * The server now sends UNKNOWN_COMMAND error status if client sends
3407 unknown command. Affected file silcd/command.c.
3409 * All server commands now handle the command identifier the right
3410 way when sending the command reply to the client. The client can
3411 use to identify the command replies with the identifier.
3413 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added silc_server_get_client_route to resolve the route to
3416 the client indicated by the client ID. Affected file is
3419 * Added silc_server_relay_packet as general function to relay
3420 packet to arbitrary destination. This deprecates functions
3421 like _send_private_message_key, _relay_notify etc. Affected
3422 file is silcd/packet_send.[ch].
3424 Removed silc_server_send_key_agreement,
3425 silc_server_send_private_message_key and
3426 silc_server_packet_relay_notify functions from the file
3427 silcd/packet_send.[ch].
3431 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3432 server. Affected file silcd/packet_receive.[ch].
3434 * Implemented the KILL command to the client. Implemented the
3435 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3436 Affected files lib/silcclient/command[_reply].c and
3437 lib/silcclient/client_notify.c. Implemented the KILL notify
3438 printing in the user inteface.
3440 * Fixed a lot silc_parse_nick memory leaks from the client
3441 library in the file lib/silcclient/command.c.
3443 * Changed the silc_server_send_notify_on_channels's `sender'
3444 argument from SilcSocketConnection to SilcClientEntry to
3445 check the sender as entry and not as connection object and not
3446 to send to the client provided as argument. The affected file
3447 is silcd/packet_send.[ch].
3449 * The notify packets that are destined directly to the client used
3450 to not to be processed by the server. Now changed that and the
3451 server processes all notify packets. After relaying the packet
3452 to the client the notify packet is processed in the server.
3454 * The silc_server_free_client_data now checks whether there is
3455 pending outgoing traffic for the client and purges the data to
3456 the network before removing the client entry.
3458 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3461 an client is killed from the SILC Network. Updated the protocol
3464 Added new function silc_server_send_notify_killed to the
3465 silcd/packet_send.[ch].
3467 * Added function silc_server_packet_relay_notify to relay notify
3468 packets that are destined directly to a client. In this case
3469 the server does not process the notify packets but merely relays
3470 it to the client. Affected file silcd/packet_send.[ch].
3472 Added also silc_server_packet_process_relay_notify to check
3473 whereto relay the notify. Affected file is
3474 silcd/packet_receive.[ch].
3476 * Implemented the KILL command to the server.
3480 * Added the backup schema desgined last fall to the protocol
3481 specs for everyone to see. The specification is in the
3482 *-spec-xx.txt draft and the packet type definitions for the
3483 backup routers is in *-pp-xx.txt draft. Thusly, added also
3484 new packet type SILC_PACKET_CELL_ROUTERS.
3486 * A big security problem in the implementation discovered. The
3487 signoff of an client did not cause new channel key generation
3488 which it of course should've done. The channel keys must be
3489 always re-generated when client leaves (or signoffs) the channel.
3490 The silc_server_remove_from_channels funtion now handles
3491 the channel key re-generation.
3493 * Added `sender' argument to the silc_server_send_notify_on_channels
3494 to not to send the client provided as argument. Affected file
3495 silcd/packet_send.[ch].
3497 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Implemented OPER and SILCOPER commands into the server and
3502 * Added silc_auth_verify and silc_auth_verify_data to verify
3503 the authentication directly from the authentication payload.
3504 It supports verifying both passphrase and public key based
3505 authentication. Affected file lib/silccore/silcauth.[ch].
3507 * Added `hash' field to the SilcIDListData structure. It is the
3508 hash negotiated in the SKE protocol. Affected file is
3511 * Slight redesigning of the SilcAuthPayload handling routines.
3512 Do not send SilcPKCS but SilcPublicKey as argument.
3514 * Implemented the public key authentication support to the
3515 serverconfig. The public key is loaded from the provided path
3516 and saved as authentication data to void * pointer. Thus,
3517 changed the unsigned char *auth_data to void *auth_data;
3519 * Fixed SHUTDOWN command to send the reply before the server
3520 is shutdown. :) Affected file silcd/command.c.
3522 * Fixed fatal bug in CONNECT command. The hostname was invalid
3523 memory and server crashed. Affected file silcd/command.c.
3525 * Fixed fatal bug in CLOSE command. The server_entry became
3526 invalid but was referenced later in the command. Affected file
3529 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Fixed fatal bug in failure packet handling. Server ignored
3532 the failure and thus crashed when it came.
3536 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3539 that the command may be executed only once in (about) 2 seconds.
3540 The old SILC_CF_LAG flag is same but allows command bursts up
3541 to five before limiting.
3543 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3544 server code. Various commands now includes the CF_LAG_STRICT
3545 flag to disallow any kind of miss-use of the command.
3547 * Fixed the silc_buffer_unformat to not to allocate any data
3548 if the length of the data is zero. It used to allocate the
3549 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3551 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Changed the format of AdminConnection configuration section
3554 in the server. Added username of the admin to the format.
3555 Affected files silcd/serverconfig.[ch].
3557 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3558 to return admin configuration data by host, username and/or
3561 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Implemented WHOWAS command to the server. Added the functions:
3565 silc_server_command_whowas_parse,
3566 silc_server_command_whowas_send_reply,
3567 silc_server_command_whowas_from_client and
3568 silc_server_command_whowas_from_server
3570 * Added <Client ID> argument to the WHOWAS command reply. Updated
3571 the protocol specs accordingly.
3573 * Implemented WHOWAS command and command_reply to the client
3576 Implemented the WHOWAS printing on the user interface.
3578 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Added new argument to the WHOWAS command reply, the real name.
3581 It is an optional argument. Updated the protocol specs.
3583 * Added SilcIDCacheDestructor callback that is registered when
3584 the SilcIDCache is allocated. The callback is called when
3585 an cache entry in the ID Cache expires, or is purged from the
3586 cache. Added into lib/silccore/idcache.[ch].
3588 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3589 to destruct the client entries when the cache entry expires.
3590 Other ID Cache's in server and in the client library ignores
3593 * If the ID Cache entry's `expire' field is zero then the entry
3594 never expires. Added boolean `expire' argument to the
3595 silc_idcache_add function in the lib/silccore/idcache.[ch].
3596 If it is TRUE the default expiry value is used.
3598 * Added silc_server_free_client_data_timeout that is registered
3599 when client disconnects. By default for 5 minutes we preserve
3600 the client entry for history - for WHOWAS command.
3602 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Added support to the server to enforce that commands are not
3605 executed more than once in 2 seconds. If server receives
3606 commands from client more frequently, timeout is registered
3607 to process the commands. Affected file silcd/command.c.
3608 Added new function silc_server_command_process_timeout.
3610 * Changed NICK_NOTIFY handling in client library to check that
3611 if the client's nickname was changed, so there is no need to
3612 resolve anything from the server.
3614 * Removed error printing from the WHOIS and IDENTIFY commands.
3615 If error occurs then it is ignored silently in the client library.
3616 The application, however, may map the received error to
3617 human readable error string. The application currently maps
3618 the NO_SUCH_NICKNAME error to string.
3620 * Made the command status message public to the application. Moved
3621 them from lib/silcclient/command_reply.c to
3622 lib/silcclient/command_reply.h. The application can map the
3623 received command status to the string with the
3624 silc_client_command_status_message function.
3626 * Added check to the server to check that client's ID is same
3627 as the Source ID in the packet the client sent. They must
3630 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Added dist-bzip hook to the Makefile.am to make bzip2
3633 compressed distributions.
3635 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Server now enforces the maximum length for the nickname and
3638 the channel as protocol specification dictates. 128 bytes for
3639 nickname and 256 bytes for channel name.
3641 * Moved the WHOIS printing to the application. The client libary
3642 does not print out the WHOIS information anymore, the application
3643 must do it. Renamed silc_client_command_reply_whois_print to
3644 the silc_client_command_reply_whois_save.
3646 The client's idle time is also sent to the application now, and
3647 the idle is shown on screen.
3649 * Added silc_client_command_reply_identify_save to save the
3650 received IDENTIFY entries.
3652 * Do not check for channel private keys in message sending and
3653 reception if the channel does not have the PRIVKEY mode set.
3654 Affected file lib/silclient/client_channel.c.
3656 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3659 just surfaced after chaning the JOIN procedure.
3661 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Added silc_client_get_clients_by_list to get client entries
3664 from Client ID list, that is returned for example by JOIN
3665 and USERS command replies. The application should use this
3666 function for example when JOIN command reply is received to
3667 resolve the clients already on the channel (library does not
3668 do that anymore as USERS command reply is not used in the JOIN
3669 procedure anymore). Affected files lib/silcclient/silcapi.h and
3670 lib/silcclient/idlist.c.
3672 * JOIN command reply and USERS command reply returns now SilcBuffer
3673 pointers instead of unsigned char pointers when returning
3674 the client list and mode list.
3676 * Added <Client ID> argument to the JOIN command reply, mainly
3677 for the server to identify for which client the command was
3678 originally sent. Updated protocol specs accordingly.
3680 * Added SilcDlist private_key pointer to the SilcChannelEntry
3681 in the client to support the channel private keys. Affected
3682 file is lib/silcclient/idlist.h.
3684 * Added SilcChannelPrivateKey argument to the function
3685 silc_client_send_channel_message so that application can choose
3686 to use specific private ke if it wants to. If it is not provided,
3687 the normal channel key is used, unless private keys are set.
3688 In this case the first (key that was added first) is used
3689 as the encryption key.
3691 * Implemented the support for channel private key handling.
3692 Implemented the following functions:
3694 silc_client_add_channel_private_key,
3695 silc_client_del_channel_private_keys,
3696 silc_client_del_channel_private_key,
3697 silc_client_list_channel_private_keys and
3698 silc_client_free_channel_private_keys
3700 Affected file lib/silcclient/client_channel.c.
3702 * Added the support for the private keys in the channel message
3703 sending and encryption and in the message reception and
3704 decryption. Affected funtions are
3705 silc_client_send_channel_message and silc_client_channel_message.
3707 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Added SKE's key verify callback to the client library's
3710 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3712 * Removed the statement that server (or router) must send USERS
3713 command reply when joining to the channel so that the client
3714 knows who are on the channel. Instead, the client list and
3715 client's mode list is now sent in the JOIN command reply to the
3716 client who joined channel. This is better solution.
3718 * Added function silc_server_get_users_on_channel and function
3719 silc_server_save_users_on_channel to the silcd/server.[ch].
3721 * Removed function silc_server_command_send_users from the
3724 * Do not show topic on the client library anymore. The topic is
3725 sent in the command reply notify to the application and the
3726 application must show the topic now.
3728 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Added client searching by nickname hash into the IDENTIFY and
3731 WHOIS commands in the server as they were clearly missing from
3732 them. Affected file is silcd/command.c.
3734 * Fixed a bug in private message receiving in the client library.
3735 The remote ID was freed and it wasn't supposed, now it is
3738 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Minor fix to the channel payload; allocate the data area, as it
3741 needs to be of specific length.
3743 * If the key agreement port is zero then the operating
3744 system will define the bound port. Affected files are
3745 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3747 * Added new function silc_channel_payload_decrypt into the file
3748 lib/silccore/silcchannel.[ch].
3750 * Moved the channel message etc, check from silc_packet_decrypt
3751 to applications. The library calls now a generic
3752 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3753 when the packet is either normal or special. This was done to
3754 allow more wide range of checking that was not allowed when
3755 the code was in library. Now applications can do virtually any
3756 checks to the packet and return to the library the decision how
3757 the packet should be processed. Affected files are
3758 lib/silccore/silcpacket.[ch].
3760 Added silc_server_packet_decrypt_check to the server and
3761 silc_client_packet_decrypt_check to the client library.
3763 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3764 to send with specified source and destination information.
3766 * Channel message delivery between routers was broken after the
3767 channel key distribution was fixed earlier. The channel key
3768 was used be to distributed to other routers as well which is not
3769 allowed by the protocol. Now this is fixed and channel keys
3770 really are cell specific and the channel message delivery between
3771 routers comply with the protocol specification.
3773 * Fixed various commands in server to check also the global list
3774 for the channel entry and not just the local list. The affected
3775 file silcd/command.c.
3777 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Added assert()s to buffer formatting and unformatting routines
3780 to assert (if --enable-debug) when error occurs. Affected
3781 file: lib/silcutil/silcbuffmt.c.
3783 * Changed to auto-reconnect to check whether the remote host is
3784 router and register the re-connect timeout if it is. It used
3785 to check that whether we are normal server, but router must do
3786 auto-reconnect with another router as well. Affected file
3789 * Removed the [<key len>] option from CMODE command as the cipher
3790 name decides the key length, nowadays. See the defined ciphers
3791 from the protocol specification.
3793 * Added [<hmac>] option to the CMODE command to define the HMAC
3794 for the channel. Added SILC_CMODE_HMAC channel mode.
3796 * Added [<hmac>] option for the JOIN command so that user can
3797 select which HMAC is used to compute the MACs of the channel
3800 * Added Hmac field to the Channel Message Payload. The integrity
3801 of plaintext channel messages are now protected by computing
3802 MAC of the message and attaching the MAC to the payload. The
3803 MAC is encrypted. Now, it is clear that this causes some
3804 overhead to the size of the packet but rationale for this is that
3805 now the receiver can verify whether the channel message decrypted
3806 correctly and also when private keys are set for the channel the
3807 receiver can decrypt the packet with several keys and check from
3808 the MAC which key decrypted the message correctly.
3810 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3811 lib/silccrypt/silccipher.[ch].
3813 * Added silc_hash_len to return the digest length into the
3814 lib/silcrypt/silchash.[ch].
3816 * Rewrote parts of Silc Channel Payload interface in the
3817 lib/silccore/silcchannel.[ch]. The encode function now also
3818 encrypts the packet and parse function decrypts it.
3820 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Fixed a minor formatting bug in the SKE's key material processing.
3823 It actually might have processed the keys wrong way resulting
3826 * Redefined the mandatory HMAC algorithms and added new algorithms.
3827 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3828 and hmac-md5 truncated to 96 bits. The mandatory is now
3829 hmac-sha1-96. Rest are optional (including the one that used
3830 to be mandatory). Rationale for this is that the truncated HMAC
3831 length is sufficient from security point of view and can actually
3832 make the attack against the HMAC harder. Also, the truncated
3833 HMAC causes less overhead to the packets. See the RFC2104 for
3836 * Added new [hmac] configuration section. The SKE used to use
3837 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3838 is of course wrong. The official names that must be proposed in
3839 the SKE are the ones defined in the protocol specification
3840 (hmac-sha1-96 for example). The user can configure any hmac
3841 using any hash function configured in the [hash] section. At
3842 least, the mandatory must be configured.
3844 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3846 * Added HMAC list to the SKE proposal list. It has now both
3847 hash algorithm list and HMAC list. This makes the protocol
3848 incompatible with previous versions. The SKE now seems to work
3849 the way it is supposed to work, for the first time actually.
3851 * Defined plain Hash algorithms to the protocol specification.
3854 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Implemented support for key agreement packets into the server.
3857 Added functions silc_server_key_agreement and
3858 silc_server_send_key_agreement. Other than these functions,
3859 server has nothing to do with this packet.
3861 * Added support for private message key packets into the server.
3862 Added functions silc_server_private_message_key and
3863 silc_server_send_private_message_key.
3867 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3868 called in the protocol's final callback instead in the END
3869 protocol state. This makes a little more sense and in the same
3870 time in client we can use the same protocol routines for normal
3871 key exchange and to key agreement packet handling as well.
3873 * Added to both client's and server's KE protocol context the
3874 SilcSKEKeyMaterial pointer to save the key material. We will
3875 bring the key material to the protocol's final callback by doing
3876 this. The final callback must free the key material.
3878 * Added SKE's packet_send callback into client's KE protocol
3879 context so that the caller can choose what packet sending function
3880 is used. This way we can use different packet sending when
3881 doing normal SKE when doing key agreement packet handling (in
3882 the key agreement packet handling we do not want to encrypt
3885 * Implemented the responder side of the key agreement routines
3886 in the client. The client can now bind to specified port and
3887 accept incoming key negotiation. The key material is passed
3888 to the application after the protocol is over.
3890 * Implemented the processing of incoming Key Agreement packet
3891 in the client. Added function silc_client_key_agreement to
3894 * Implemented the intiator side of the key agreement routines
3895 in the client. The client can now initiate key agreement with
3896 another remote client. The key material is passed to the
3897 application after the protocol is over.
3899 * Created client_keyagr.c to include all the key agreement
3902 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3903 SILC_TASK_CALLBACK except that it is not static.
3905 * Created client_notify.c and moved the Notify packet handling
3906 from the client.[ch] into that file.
3908 * Created client_prvmsg.c and moved all private message and
3909 private message key routines from the client.[ch] into that file.
3911 * Create client_channel.c and moved all channel message and
3912 channel private key routines from the client.[ch] into that file.
3914 * Changed silc_client_get_client_by_id_resolve to resolve with
3915 WHOIS command instead of IDENTIFY command, in the file
3916 lib/silclient/idlist.c.
3918 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Implemented the SKE's responder side to the Client library.
3922 * When FAILURE is received to the protocol do not trust it
3923 blindly. Register a timeout to wait whether the remote closes
3924 the connection as it should do it, only after that process the
3925 actual failure. This was changed to both client and server.
3927 * Added client_internal.h to include some of the structures
3928 there instead of client.h in lib/silcclient/.
3930 * Added function silc_task_unregister_by_callback to unregister
3931 timeouts by the callback function.
3933 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Some "Incomplete WHOIS info" errors has been appearing on the
3936 log files. Took away the entry->userinfo check from WHOIS
3937 reply sending. The entry->userinfo is now " " if client did not
3938 provide one. I thought this was fixed earlier but something
3939 is wrong still. Let's see if the error still appears.
3941 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Fixed a minor bug in the login when the channel key is
3944 re-generated in the server. It used to generate the key in
3945 wrong order and thus caused problems in the channel traffic.
3947 * Fixed a minor bug in channel key distsribution after
3948 KICK command. The key was not sent to the router even though
3951 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Added silc_ske_process_key_material_data as generic routine
3954 to process any key material as the SILC protocol dictates. The
3955 function is used by the actual SKE library but can be used by
3956 applications as well. This relates to the private message keys
3957 and the channel private keys since they must be processed the
3958 same way the normal SILC session keys. The protocol dictates
3959 this. Affected files: lib/silcske/silcske.[ch].
3961 Added also silc_ske_free_key_material to free the
3962 SilcSKEKeyMaterial structure.
3964 * Defined silc_cipher_set_key function to set the key for
3965 cipher without using the object's method function. The affected
3966 files: lib/silccrypt/silccipher.[ch].
3968 * Implemented silc silc_client_add_private_message_key,
3969 silc_client_add_private_message_key_ske,
3970 silc_client_del_private_message_key,
3971 silc_client_list_private_message_keys and
3972 silc_client_free_private_message_keys functions in the
3975 Added functions silc_client_send_private_message_key to send
3976 the Private Message Key payload and silc_client_private_message_key
3977 to handle incoming Private Message Key payload.
3979 * Added Cipher field to the Private Message Key payload to set
3980 the cipher to be used. If ignored, the default cipher defined
3981 in the SILC protocol (aes-256-cbc) is used.
3983 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Removed lib/silcclient/ops.h file.
3987 Redefined parts of the SILC Client Library API. Created new
3988 file silcapi.h that deprecates the ops.h file and defines the
3989 published Client Library API. Defined also private message key
3990 API and channel private key API into the file.
3992 This is the file that the application must include from the
3993 SILC Client Library. Other files need not be included by
3994 the application anymore.
3996 * Added new key_agreement client operation callback and also
3997 defined the Key Agreement library API for the application.
3999 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4002 is used by clients to request key negotiation between another
4003 client in the SILC network. If the negotiation is started it
4004 is performed using the SKE protocol. The result of the
4005 negotiation, the secret key material, can be used for example
4006 as private message key.
4008 Implemented the Key Agreement payload into the files
4009 lib/silccore/silauth.[ch].
4011 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Redefined ciphers for the SILC protocol. Added some new ciphers
4014 and defined the key lengths for the algorithms. Changed the
4015 code accordingly. The default key length is now 256 bits.
4017 * Fixed SKE key distribution function silc_ske_process_key_material
4018 when the key length is more than 128 bits. The default key
4019 length in SILC is now 256 bits.
4021 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4022 to indicate unsupported algorithm.
4024 * Renamed rijndael.c to aes.c and all functions as well.
4026 * Fixed a long standing channel key setting bug in client library.
4027 Weird that it has never surfaced before.
4029 * Fixed bug in channel deletion. If the entire channel is removed
4030 then it must also delete the references of the channel entry
4031 from the client's channel list as the client's channel entry and
4032 the channel's client entry share same memory.
4034 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Implemented CONNECT and SHUTDOWN commands in the client.
4038 * Implemented CLOSE command to the client.
4040 * Added the function silc_idlist_find_server_by_name into the
4041 files silcd/idlist.[ch].
4043 Added the function silc_idlist_find_server_by_conn into the
4044 files silcd/idlist.[ch].
4046 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * DIE command was renamed to SHUTDOWN. Updated the both code
4051 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4052 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4054 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4057 * Added function silc_server_create_connection function to create
4058 connection to remote router. My server implementation actually
4059 does not allow router to connect to normal server (it expects
4060 that normal server always initiates the connection to the router)
4061 so the CONNECT command is only good for connecting to another
4064 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4067 or some other client was kicked from the channel.
4069 Implemented the handling of the notify type to both client
4072 Implemented silc_server_send_notify_kicked to send the KICKED
4073 notify. It is used to send it to the server's primary router.
4075 * Implemented the KICK command into server and client.
4077 * Added `query' argument to the silc_idlist_get_client function
4078 to indicate whether to query the client from server or not if
4081 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4082 to indicate that the client is not channel founder.
4086 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Removed the rng context from SilcPacketContext structure and
4089 changed that the packet routine uses the Global RNG API.
4091 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Added support for quit message that client can "leave" on the
4094 channel when it quits the SILC. It is ditributed inside the
4095 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4097 Added silc_server_free_client_data that will take the
4098 signoff message as argument.
4100 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4102 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Updated parts of the protocol specification to keep it up
4107 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4110 payloads in one packet.
4112 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4113 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4114 use now the new List flag.
4116 * Also deprecated the following packet types: REPLACE_ID,
4117 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4119 * Added list support for Notify packet in server.
4121 * Added silc_server_send_notify_channel_change to send the
4122 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4123 the silc_server_send_replace_id.
4125 * Added silc_server_send_notify_nick_change to send the
4126 NICK_CHANGE notify type. Deprecates the function
4127 silc_server_send_replace_id.
4129 * Added silc_server_send_notify_join to send the JOIN notify type.
4130 Deprecates the function silc_server_send_new_channel_user.
4132 * Added silc_server_send_notify_leave to send LEAVE notify type.
4133 Deprecates the function silc_server_send_remove_channel_user.
4135 * Added silc_server_send_notify_cmode and
4136 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4137 types. Deprecates the silc_server_send_set_mode function.
4139 * Added SERVER_SIGNOFF notify type to indicate that server has
4140 quit. This means that all clients on the channel from that
4141 server will drop. This can be also used when netsplit happens.
4143 Deprecated REMOVE_ID packet type since it is not needed anymore
4146 Added silc_server_send_notify_server_signoff to send the
4147 SERVER_SIGNOFF notify type. Deprecates the function
4148 silc_server_send_remove_id.
4150 Added also silc_server_send_notify_signoff to send the
4151 SIGNOFF notify type.
4153 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4154 SILC protocol from this day on. Changed the protocol
4155 specification as well.
4157 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4158 notify type. It is used between routers to notify about
4159 topic changes on a channel.
4161 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4164 * Partly updated the protocol specification to comply with the
4165 changes now made. It is still though a bit outdated.
4167 * The JOIN notify type now takes one extra argument <Channel ID>.
4168 The packet used to be destined to the channel but now the
4169 JOIN type may be sent as list thus it is impossible to
4170 destine it to any specific channel. By adding this argument
4171 it is again possible.
4173 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Added CREDITS file. The CHANGES and CREDITS file will appear
4176 in the distribution as well.
4178 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4181 types in the server's silcd/packet_receive.c.
4183 * Implemented CMODE and CUMODE to work in router environment.
4185 * Fixed minor encoding and decoding buglet from the
4186 lib/silccore/silcmode.c.
4188 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4191 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4193 * Changed all SilcConfigServer* and silc_config_server* to
4194 SilcServerConfig* and silc_server_config*, respectively.
4197 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Associated the ID (client or server ID) to the Authentication
4200 Payload to avoid any possibility of forging. Updated the
4201 protocol specification and the code accordingly.
4203 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * The RSA key length is now save to the RsaKey context in the
4206 key generation process in lib/silccrypt/rsa.c. The key length
4207 is now used to figure out the maximum size of the block allowed
4208 to be encrypted/signed.
4210 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4211 is equivalent to the silc_mp_mp2bin but does not allocate any
4214 * Changed silc_mp_mp2bin API to take length argument. If it is
4215 non-zero then the buffer is allocated that large. If zero, then
4216 the size is approximated using silc_mp_sizeinbase, which however
4219 * Created Global RNG API which is global RNG that application can
4220 initialize. After initializing, any routine anywhere in the
4221 code (including library) can use RNG without allocating a new
4222 RNG object. This was done to allow this sort of use of the
4223 RNG in code that has no chance to allocate RNG object. All
4224 applications currently allocate this and many routines in the
4225 library use this. Affected file lib/silccrypt/silcrng.[ch].
4227 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4228 it to use the Global RNG API.
4230 * Defined Authentication Payload into protocol specification that
4231 is used during SILC session to authenticate entities. It is
4232 used for example by client to authenticate itself to the server
4233 to obtain server operator privileges.
4235 Implemented this payload into the lib/silccore/silcauth.[ch].
4236 Implemented also routines for public key based authentication
4237 as the new protocol specification dictates.
4239 Moved definitions of different authentication methods from
4240 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4242 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4243 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4244 silc_pkcs_verify_with_hash functions into the file
4245 lib/silccrypt/silcpkcs.[ch].
4247 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * The client entry's userinfo pointer must be always valid.
4250 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4251 will fail since it requires the userinfo. Now, the userinfo
4252 is allocated as "" if actual userinfo does not exist. Actually,
4253 it must exist and it is totally Ok to drop client connections
4254 that does not announce the userinfo. However, we will make
4255 this workaround for now.
4257 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4258 to return the remote port by socket.
4260 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4263 SILC_SERVER_PENDING_EXEC and added an new macro
4264 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4265 data or when error occurs while processing the pending command.
4267 Added new argument `destructor' into silc_server_command_pending
4268 and to the SilcServerCommandPending object. This destructor is
4269 now called after calling the pending callback or if error occurs
4270 immediately. If error occurs the actual pending callback won't
4271 be called at all - only the destructor. The destructor may be
4272 NULL if destructor is not needed.
4274 All this applies for client library code as well. Similar
4275 changes were made there as well for the pending commands.
4277 In the client, the application must now allocate the
4278 SilcClientCommandContext with the silc_client_command_alloc
4281 * Added reference counter to the SilcServerCommandContext. Added
4282 function silc_server_command_alloc and silc_server_command_dup
4285 Same type of functions added to the client library for the same
4288 * Removed the cmd_ident from IDListData away since it is now
4289 global for all connections. It is the command identifier used
4290 in command sending and with pending commands. The affected file
4293 * Added reference counter to the SilcSocketConnection objecet to
4294 indicate the usage count of the object. The object won't be
4295 freed untill the reference counter hits zero. Currently only
4296 server uses this, and client ignores it. The client must be
4297 set to use this too later. The affected files are
4298 lib/silccore/silcsockconn.[ch]. Added also the function
4299 silc_socket_dup to increase the reference counter.
4301 This was mainly added because it is possible that the socket
4302 is removed underneath of pending command or other async
4303 operation. Now it won't be free'd and proper DISCONNECTING
4304 flags, etc. can be set to avoid sending data to connection that
4305 is not valid anymore.
4307 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4308 the connection. After that it sets SILC_SET_DISCONNECTED.
4309 It is, however, possible that the socket data is not still freed.
4310 The silc_server_packet_process now checks that data is not
4311 read or written to connection that is DISCONNECTED. The socket
4312 get's freed when the reference counter hits zero.
4314 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Changed the client operation API: channel_message operation's
4317 `sender' is now the client entry of the sender, not the nickname
4318 and the `channel' is the channel entry, not the channel name.
4320 In the private_message operation the `sender' is now also the
4321 client entry of the sender not the nickname.
4323 Affected file is lib/silcclient/ops.h and all applications
4324 using the client operations.
4326 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Moved the calling of ops->connect() from connect_to_server_final
4329 into receive_new_id functin since that is the point when the
4330 client is actually allowed to send traffic to network. The
4331 affected file is lib/silcclient/client.c.
4333 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4336 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4337 (if needs broadcasting) instead of broadcasting the packets one
4338 by one which would make a burst in the network traffic.
4340 * Added `broadcast' argument to the functions in silcd/server.[ch]
4341 silc_server_create_new_channel[_with_id] to indicate whether
4342 to send New Channel packet to primary router.
4344 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Added new function into the silcd/server.[ch] files:
4347 silc_server_create_new_channel_with_id to create new channel with
4348 already existing Channel ID.
4350 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4351 lib/silccore/silcpacket.h. This packet is used t send list of
4352 Set Mode payloads inside one packet. Server uses this to set
4353 the modes for the channels and clients on those channels, that it
4354 announced to the router when it connected to it. The protocol
4355 specification has been updated accordingly.
4357 * The silc_server_new_channel did not handle the packet coming
4358 from normal server as it normally does not send that. However,
4359 when it announces its channels it does send it. Implemented
4360 the support for that.
4362 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4363 into the file lib/silccore/id.h.
4365 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Fixed memory leaks in the functions silc_idlist_del_client,
4368 silc_idlist_del_channel and silc_idlist_del_server in the file
4369 silcd/idlist.c. All of those leaked like a sieve.
4371 * Fixed some small memory leaks in the client's function
4372 silc_client_notify_by_server.
4374 * Added functions into silcd/server.c: silc_server_announce_clients,
4375 silc_server_announce_channels and silc_server_announce_server.
4376 These functions are used by normal and router server to announce
4377 to its primary router about clients, channels and servers (when
4378 router) that we own. This is done after we've connected to the
4381 These functions effectively implements the following packet types:
4382 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4383 and SILC_PACKET_NEW_ID_LIST.
4385 * Added new functions into the silcd/packet_receive.[ch]:
4386 silc_server_new_id_list, silc_server_new_channel_list and
4387 silc_server_new_channel_user_list to handle the incoming
4388 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4390 * Added support of changing Channel ID in the function
4391 silc_server_replace_id. If the server that announces a channel
4392 to the router already exists in the router (with same name but
4393 with different Channel ID), router is responsible to send
4394 Replace ID packet to the server and force the server to change
4395 the Channel ID to the one router has.
4397 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4398 client that the Channel ID has been changed by the router. The
4399 normal server sends this to the client. Client must start using
4400 the new Channel ID as the channel's ID.
4402 Implemented handling of this new type into lib/silcclient/client.c
4403 into the function silc_client_notify_by_server.
4405 * Added new function silc_idlist_replace_channel_id into the files
4406 silcd/idlist.[ch] to replace the Channel ID.
4408 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Call silc_server_command_identify_check always when processing
4411 the IDENTIFY command in silcd/command.c
4413 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4416 send keepalive packets. The packet can be sent by clients,
4417 servers and routers.
4419 Added function silc_socket_set_heartbeat into the file
4420 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4421 If not set, the heartbeat is not performed. The actual
4422 heartbeat is implemented in the low level socket connection
4423 library. However, application is responsible of actually
4426 Added silc_server_send_heartbeat to send the actual heartbeat
4427 packet into silcd/packet_send.[ch]. Server now performs
4428 keepalive with all connections.
4430 * Added silc_task_get_first function into lib/silcutil/silctask.c
4431 to return the timeout task with shortest timeout. There was a bug
4432 in task unregistration that caused problems. TODO has been
4433 updated to include that task system must be rewritten.
4435 * The client library will now resolve the client information when
4436 receiving JOIN notify from server for client that we know but
4437 have incomplete information.
4439 * Rewrote parts of silc_server_remove_from_channels and
4440 silc_server_remove_from_one_channel as they did not remove the
4441 channel in some circumstances even though they should've.
4443 * Encryption problem encountered in server:
4445 The LEAVE command used to send the Channel Key packet to the
4446 router immediately after generating it. However, the code
4447 had earlier sent Remove Channel user packet but not immediately,
4448 ie. it was put to queue. The order of packets in the router
4449 was that Channel Key packet was first and Remove Channel User
4450 packet was second, even though they were encrypted in the
4451 reverse order. For this reason, MAC check failed. Now, this
4452 is fixed by not sending the Channel Key packet immediately but
4453 putting it to queue. However, this is more fundamental problem:
4454 packets that are in queue should actually not be encrypted
4455 because packets that are sent immediately gets encrypted
4456 actually with wrong IV (and thus MAC check fails). So, packets
4457 that are in queue should be encrypted when they are sent to
4458 the wire and not when they put to the queue.
4460 However, the problem is that the current system has not been
4461 designed to work that way. Instead, the packet is encrypted
4462 as soon as possible and left to the queue. The queue is then
4463 just purged into wire. There won't be any fixes for this
4464 any time soon. So, the current semantic for packet sending
4467 o If you send packet to remote host and do not force the send
4468 (the packet will be in queue) then all subsequent packets to the
4469 same remote host must also be put to the queue. Only after the
4470 queue has been purged is it safe again to force the packet
4473 o If you send all packets immediately then it safe to send
4474 any of subsequent packets through the queue, however, after
4475 the first packet is put to queue then any subsequent packets
4476 must also be put to the queue.
4478 Follow these rules and everything works fine.
4480 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Added new function silc_server_remove_clients_by_server to
4483 remove all client entries from ID list when the server connection
4484 is lost. In this case it is also important to invalidate all
4485 client entires as they hold the invalid server entry. This
4486 fixes fatal bug when server has lost connection and will reconnect
4489 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Made some sanity checks to silc_server_daemonise like to check
4492 whether the requested user and group actually exists.
4494 * Added sanity check to SKE's silc_ske_responder_finish to check
4495 that the public and private key actually is valid.
4497 * Invalidate the client's nickname when receiving Replace ID
4498 packet and the Client ID is being replaced. This means that the
4499 server will query the nickname if someone needs it (client)
4502 * Sort the ID Cache in client library when the ID Cache data
4503 has changed (needs sorting).
4505 * Do not allow for SILC client to create several connections to
4506 several servers. The client does not support windows right now
4507 and generating multiple connections causes weird behaviour.
4509 Irssi-silc client does support windows and can handle several
4510 connections without problems, see: www.irssi.org and SILC plugin.
4512 * Fixed some places where client was added to the IDList. The
4513 rule of thumb is following (in order to get everything right):
4514 If the client is directly connected local client then the
4515 `connection' argument must be set and `router' argument must be
4516 NULL to silc_idlist_add_client function. If the client is not
4517 directly connected client then the `router' argument must
4518 bet set and the `connection' argument must be NULL to the
4519 silc_idlist_add_client function.
4521 * The funtion silc_server_packet_send_local_channel actually did
4522 not check whether the client was locally connected or not. It
4523 does that now. Fixed a bug related to LEAVE command.
4525 * Fixed Remove Channel User payload parsing bug in server's
4526 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4528 * The server's silc_server_save_channel_key now checks also the
4529 global ID list for the channel as it might not be in the local
4530 list. Fixed a bug related to LEAVE command.
4532 * Is this the end of the [<unknown>] buglet that has been lurking
4533 around for a long time? A little for loop fix in server's
4534 silc_server_command_whois_parse that is used by both IDENTIFY
4535 and WHOIS command. At least, this was a clear bug and a cause
4536 of one type of [<unknown>] buglet.
4538 * WHOIS and IDENTIFY commands call the function
4539 silc_server_command_[whois/identify]_check function even if
4540 we are not router server.
4542 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Added --with-gmp configuration option. If set the GMP
4545 is always compiled in the SILC source tree. If not set then
4546 it is checked whether the system has the GMP3 installed. If
4547 it has then the GMP won't be compiled (the system's headers
4548 and library is used), if it doesn't have it then the GMP is
4549 compiled in the SILC source tree.
4551 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Changed RSA private exponent generation to what PKCS #1
4554 suggests. We try to find the smallest possible d by doing
4555 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4556 not security fix but optimization.
4558 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Added new config entry [Identity] to fork the server and run
4561 it as specific user and group. A patch from Bostik.
4563 * Imported Dotconf configuration library into lib/dotconf.
4564 This will be used to create the SILC configuration files later.
4565 It will appear in the distsribution after this commit.
4567 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * A big code auditing weekend happening. Auditing code for
4570 obvious mistakes, bugs and errors. Also, removing any code
4573 Removed files for being obsolete:
4575 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4576 inline in the file lib/silcutil/silcbuffer.h)
4578 o lib/silcutil/silcbufutil.c (the header has inline versions)
4580 Changed code to fix possible error conditions:
4582 o The buffer formatting routines now check that the destination
4583 buffer really has enough space to add the data. This applies for
4584 both buffer formatting and unformatting
4585 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4586 unformatting was changed to accomodate following rules:
4587 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4588 sent to the function while XXX_*STRING will not allocate or copy
4589 the data into the buffer. Instead it sets the pointer from the
4590 buffer into the pointer sent as argument (XXX_*STRING used to
4591 require that the pointer must be allocated already). This change
4592 makes this whole thing a bit more consistent and more optimized
4593 (note that the data returned in the unformatting with XXX_*STRING
4594 must not be freed now). The routines return now -1 on error.
4596 o Tried to find all code that use buffer_format and buffer_unformat
4597 and added return value checking to prevent formatting and
4598 especially unformatting errors and possible subsequent fatal
4601 o Changed ske->x and ske->KEY to mallocated pointers in
4602 lib/silcske/silcske.h. Fixed possible data and memory leak.
4604 o Added return value checking to all *_parse* functions. Fixed
4605 many memory leaks as well.
4607 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4608 so that buffer overflows would not happen. All code now also
4609 checks the return value as it can fail.
4611 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Added reconnection support to server if the normal server looses
4614 its connection to the router (for example if router is rebooted).
4615 The server performs normal reconnection strategy implemented
4616 to the server. Affected file silcd/server.c.
4618 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Added new packet type SILC_PACKET_SET_MODE that is used to
4621 distribute the information about changed modes (for clients,
4622 channels and clients channel modes) to all routers in the
4623 network. Updated the protocol specification accordingly.
4625 Added functions into silcd/packet_send.c and
4626 silcd/packet_receive.c: silc_server_send_set_mode,
4627 silc_server_set_mode.
4629 Added new files silcmode.[ch] into lib/silccore that implements
4630 the encoding and decoding of Set Mode Payload. Added new type
4631 SilcSetModePayload. Moved the definitions of different modes
4632 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4634 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Oops, a little mistake in server's connection authentication
4637 protocol. The protocol is not ended with FAILURE but with
4638 SUCCESS if the authentication is Ok. :) Affected file is
4641 * Implemented NICK_CHANGE notify handling in server in the file
4642 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4643 the local clients on the channel. After the changing nickname
4644 in router environment snhould work and the [<unknown>] nickname
4645 should appear no more.
4647 The silc_server_replace_id function that receives the Replace ID
4648 payload now sends the NICK_CHANGE notify type also in the file
4649 silcd/packet_receive.c
4651 * Changed WHOIS and IDENTIFY command to support the maximum amount
4652 of arguments defined in protocol specs (3328 arguments). This
4653 fixed a bug that caused problems when there were more than three
4656 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Added extra parameter, command identifier, to the
4659 silc_client_send_command so that explicit command identifier
4662 Changed that ID list routines uses specific command identifier
4663 when sending WHOIS/IDENTIFY requests to the server so that they
4664 can be identified when the reply comes back.
4666 Affected files lib/silcclient/command.[ch],
4667 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4669 * Added `sender' argument to silc_server_packet_send_to_channel
4670 to indicaet the sender who originally sent the packet to us
4671 that we are now re-sending. Ignored if NULL. Affected file
4672 silcd/packet_send.[ch].
4674 * Added some server statistics support in silcd/server_internal.h
4675 SilcServerStatistics structure and around the server code. Also
4676 send some nice statistics information when client is connecting
4679 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Fixed channel ID decoding in server's JOIN command reply in
4682 silcd/command_reply.c
4684 * Fixed braodcasting of replace ID payload to not to send it if
4685 we are standalone server in silcd/packet_receive.c.
4687 * Fixed all channel message sending routines to not to send
4688 packets to clients that has router set, since they are routed
4689 separately in the same function earlier. Affects file
4690 silcd/packet_send.c and all channel packet sending functions.
4692 * In USERS reply, res_argv[i] are not allocated, the table
4693 is allocated. Thus changed that free the table, not its
4696 * In server's whois_check and identify_check if the client is
4697 locally connected do not send any WHOIS commands - they are not
4700 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed some minor bugs in client when sending WHOIS command. The
4703 arguments was in wrong order.
4705 * Removed statis function add_to_channel from server in
4706 silcd/command.c that was previously used with the joining but
4709 * Tested USERS command in router environment successfully with two
4710 routers, two servers and two clients.
4712 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Reorganized the USERS command and command reply in client library
4715 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4716 When the command is given by user we register a pending command
4717 callback that will reprocess the command after the reply has been
4718 received from the server. When reprocessing the packet we then
4719 display the information. Thus, the USERS information is displayed
4720 now in the command callback instead of in the command reply
4721 callback. The processing of the command is same as previously
4722 when server has sent the command reply in the JOINing process.
4724 * Added to USERS command in silcd/command_reply.c to join the client,
4725 we didn't use to know about, to the channel after we've created
4726 a client entry for it. Also, for clienet we did know already still
4727 check whether it is on the channel or not and add it if not.
4729 * Removed silc_server_command_join_notify as the function and its
4732 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Changed the client's pending command handling to the same as the
4735 server's pending command handling. It is also now possible to
4736 execute command reply functions from other command reply
4737 function as the function callbacks for commands and command
4738 replies are one and same. The pending commands are not static
4739 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4740 in client connection context. Thus, pending commands are server
4741 connection specific as it is convenient.
4743 Changed the function silc_client_command_pending and
4744 silc_client_command_pending_del and added new function
4745 silc_client_command_pending_check. Removed the
4746 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4749 * Added cmd_ident, current command identifier, to the client
4750 connection context in lib/silcclient/client.h to keep track on
4751 command identifiers used in command sending. Client's command reply
4752 function handling now supports the mandatory command identifiers.
4754 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4755 funtions in client to fully support pending command callbacks.
4757 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4758 as one of the arguments to the application in the command reply
4761 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4762 before first releasing SILC but came back. Now it is removed again
4763 and should come back nomore. The FORWARDED flag was used only
4764 by the JOINing procedure by forwarding the command packet to router.
4765 Now, the JOINing procedure has been changed to more generic (due
4766 to various router environment issues) and FORWARDED is not needed
4767 anymore for anything. The protocol specification is yet to be
4770 Now, removed silc_server_packet_forward from server and the flag
4771 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4773 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Renamed NAMES command to USERS command. The NAMES was named that
4776 due to historical reasons. Now it is renamed. Also, rewrote
4777 parts of the USERS command. The nickname list is not sent anymore
4778 by the server. Only Client ID and mode lists are sent in the USERS
4779 command. Changed this also to the protocol specification.
4781 The client now resolves the names and stuff after it receives
4782 the USERS list from the server when joining to the channel.
4784 * WHOIS and IDENTIFY commands has been changed to support multiple
4785 Client ID's per command. One can now search for multiple users
4786 in the network by sending only one WHOIS or IDENTIFY command.
4787 Changed the code and the protocol specifications.
4789 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4790 uses silc_server_command_whois_parse to parse the request. */
4792 * If normal server, do not parse the WHOIS and IDENTIFY requests
4793 before sending it to the router. Saves some time.
4795 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Fixed JOIN command on client library. Wrong number of arguments
4798 used to crash the client.
4800 * Added silc_server_channel_has_global function to check whether
4801 channel has global users or not.
4803 * Added silc_server_channel_has_local function to check whether channel
4804 has locally connected clients on the channel.
4806 * The silc_server_remove_from_one_channel now checks whether the
4807 channel has global users or not after given client was removed from
4808 the channel. It also checks whether the channel has local clients
4809 on the channel anymore. If it does not have then the channel entry
4810 is removed as it is not needed anymore.
4812 * The silc_server_notify now checks on JOIN notify whether the joining
4813 client is one of locally connected or global. If it is global then
4814 the channel has now global users on the channel and that is marked
4815 to the channel entry. Also, it now saves the global client to
4816 global list who is joining and JOINs it to the channel. This is
4817 for normal server, that is.
4819 Changed silc_server_send_notify_on_channel,
4820 silc_server_packet_relay_to_channel and
4821 silc_server_packet_send_to_channel check if we are normal server
4822 and client has router set (ie. global client) do not send the
4823 message to that client, as it is already routed to our router.
4825 * Implemented LEAVE notify type handling in silc_server_notify
4828 * Tested LEAVE command in router environment successfully. Tested
4829 with two routers, two servers and two clients.
4833 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4835 * Implemented SIGNOFF notify type handling in silc_server_notify
4838 * silc_server_remove_id now removes the client entry from all channels
4839 it has joined and thusly sends SIGNOFF notify type.
4841 * Rewrote the NAMES list generation in server by removing two excess
4842 loops. The lists are created now inside one loop.
4844 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * silc_server_remove_channel_user checks now also global list
4847 for channel and client.
4849 * silc_server_new_channel_user checks now both local and global
4850 list for channel and client. Fixed a bug in client id decoding.
4851 Used to decode wrong buffer.
4853 * silc_server_channel_message checks now both local and global
4854 list for channel entry.
4856 * Tested channel joining (hence JOIN) in router environment
4857 successfully. Tested with two routers, two servers and two
4860 * Tested channel message sending in router environment successfully.
4862 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added silc_server_save_channel_key into server.[ch] to save the
4865 received channel key in Channel Key payload processing. It is
4866 also used in JOIN command reply handling.
4868 Equivalent function silc_client_save_channel_key added into
4869 client.[ch] into client library.
4871 * Changed JOIN command reply to send information whether the channel
4872 was created or not (is existing already) and the channel key
4873 payload. Changed protocol specs accordingly.
4875 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4876 the request was sent by ID and not by nickname. Crashed on
4879 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4882 now correctly save the received data.
4884 * silc_server_free_sock_user_data now notifies routers in the
4885 network about entities leaving the network.
4887 At the same time implemented functions silc_server_remove_id
4888 and silc_server_send_remove_id to receive and send REMOVE_ID
4889 packets. The packet is used to notify routers in the network
4890 about leaving entities. The ID removed will become invalid in
4893 * Added function silc_idlist_del_server into server. Removes and
4894 free's server entry from ID list.
4896 * silc_server_private_message function now checks, if we are router,
4897 that the destination ID really is valid ID, naturally.
4899 * In router when NEW_ID packet is received (for new client) the
4900 hash of the Client ID is saved in the ID Cache but the
4901 client->nickname is set to NULL, instead of putting the hash
4904 IDENTIFY command now also checks that client->nickname must be
4905 valid. If it is not if will request the data from the server who
4906 owns the client. Added new function
4907 silc_server_command_identify_check.
4909 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4910 to set the command to already allocated Command Payload.
4912 * Tested private message sending in router environment with two
4913 routers, two servers and two clients. Fixed minor bugs and now
4916 * Fixed segfault from client's NAMES command. Used to crash if
4919 * Forwarded packets must not be routed even if it is not destined
4920 to the receiver. Changed server code comply with this.
4922 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Added `require_reverse_mapping' boolean value to ServerParams
4925 structure. If TRUE (not default) the server will require that
4926 the connecting host has fully qualified domain name.
4928 If the reverse mapping is not required and hostname could not be
4929 found the IP address is used as hostname.
4931 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Implemented version string checking to both client and server.
4934 The check is incomplete currently due to the abnormal version
4935 strings used in development version of SILC.
4937 * Changed all command functions in server to use the new
4940 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Changed char *data to unsigned char *data in ID Cache system to
4943 support binary data as ID Cache data. Changed code to support
4944 binary data in lib/silccore/idcache.c.
4946 * Renamed silc_server_packet_relay_command_reply to
4947 silc_server_command_reply as it is normal packet receiving
4948 function. Rewrote the function to accept command replys for
4949 servers and not only for clients.
4951 * Mark remote router always as registered server if we are connecting
4952 to it. Otherwise, commands sent by the router to us are ignored.
4954 * All ID List find routines now returns the ID Cache Entry pointer
4955 as well if requested.
4957 * WHOIS command works now in router environment, tested with two
4958 routers, two servers and two clients.
4960 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4961 in router environment (as it is almost equivalent to WHOIS) but
4962 hasn't been tested thoroughly. Added new functions:
4964 silc_server_command_identify_parse
4965 silc_server_command_identify_send_reply
4966 silc_server_command_identify_from_client
4967 silc_server_command_identify_from_server
4969 * Disabled route cache adding because adding two different ID's with
4970 same IP replaces the old cache entry thus giving wrong route.
4971 The entry->router->connection is always the fastest route anyway
4972 so route cache may not be needed. Of course, new routes maybe
4973 established after receiving the ID when the entry->router->connection
4974 might not be anymore the most optimal.
4976 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Add route cache for received ID for fast routing.
4980 * Added silc_server_packet_route to route received packet on router
4981 that is not destined to us.
4983 * Renamed silc_server_get_route to silc_server_route_get.
4985 * Added id_string and id_string_len fields into SilcServer to
4986 include encoded ServerID for fast comparing without excess
4987 encoding of the ID's.
4989 * Cleaned up WHOIS command on server side. Added following static
4992 silc_server_command_whois_parse
4993 silc_server_command_whois_check
4994 silc_server_command_whois_send_reply
4995 silc_server_command_whois_from_client
4996 silc_server_command_whois_from_server
4998 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4999 arguments in command replies. All command functions should be
5000 updated to use this macro.
5002 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Minor typo fixes on command reply handling on server.
5006 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Added silc_server_command_add_to_channel internal routine to add
5009 the client to the channel after router has created the channel and
5010 sent command reply to the server.
5012 * Added generic silc_server_send_command to send any command from
5015 * Use static buffer with ID rendering instead of duplicating data.
5017 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Fixed a channel user mode bug when joining to a channel server gave
5020 everybody channel founder rights, oops.
5022 * We mark ourselves as the router of the incoming server connection
5023 if we are router ourselves. This way we can check in some packet
5024 sending functions whether it is locally connected server. For
5025 incoming router connections we put NULL.
5027 * For router sending packets locally means now always sending the
5028 packet cell wide; to local clients and local servers. For normal
5029 server sending packet locally means sending it to only local
5032 * Fixed the JOIN command to really work in router environment. If the
5033 channel is created it is always created by the router. Router is
5034 also responsible of making the initial joining to the channel,
5035 sending JOIN notify to the sending server and distributing
5036 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5037 does not exist server doesn't do anything else but forward the
5038 command to the router which performs everything.
5040 * Added silc_server_send_channel_key function to send the Channel Key
5043 * Added silc_server_create_channel_key to create new channel key. The
5044 channel key is now re-generated everytime someone joins or leaves
5045 a channel, as protocol dictates. Note: channel->key_len is the
5048 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5050 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5051 packet_receive.[ch] to separate packet sending and receiving
5052 routines. The server.[ch] now includes everything else including
5053 actual packet processing (writing and reading data) and other
5056 Renamed silc_server_private_message_send_internal to
5057 silc_server_send_private_message. The routine is still though
5058 used only to relay private messages as server does not send
5059 private messages itself.
5061 Renamed silc_server_new_channel to silc_server_create_new_channel
5062 and added new function sicl_server_new_channel that handles the
5063 incoming New Channel packet. Added also new sending function
5064 silc_server_send_new_channel to send New Channel Payload.
5066 * Added new function silc_server_notify to process incoming notify
5067 packet to the server/router. Server may then relay the notify
5068 to clients if needed.
5070 * Added new function silc_server_new_channel_user to process incoming
5071 New Channel User packet. Router will redistribute the packet and
5072 send JOIN notify to its local clients and locally connected servers
5073 if needed. Normal server will send JOIN notify to its local client
5074 on same channel when received this packet. Added also corresponding
5075 sending function silc_server_send_new_channel_user to sent the
5078 * Added boolean route argument to send_notif_to_channel and
5079 packet_send_to_channel functions to attempt to route the packet
5080 if it is TRUE and send only locally if it is FALSE.
5082 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * silc_server_replace_id now broadcasts the received replace ID
5085 packet if it is not broadcast packet already. The router must
5086 broadcast to inform other routers about changed ID.
5088 * Added backpointer to server's router into SilcServer context in
5089 silcd/server_internal.h.
5091 * Fixed silc_server_packet_broadcast to send correct broadcast
5094 * The channel key is now distributed to the local client as soon
5095 as it is received from the router (in router environment) so that
5096 no other packet may be sent for the channel until client has
5099 * silc_server_remove_channel_user now broadcasts the received
5100 Remove Channel User packet if it is not broadcast packet already.
5101 The router must broadcast to inform other routers about removed
5104 * Added users field into SilcPacketContext that is a reference count
5105 of the context. One can increase the reference count by calling
5106 silc_packet_context_dup which is now changed to just increase the
5107 reference count instead of duplicating the data. The reference
5108 count is decresed by calling silc_packet_context_free that will
5109 free the data after the reference count hits zero.
5111 For now on the packet context and everything allocated into it
5112 (including the raw packet from network) must be freed by calling
5113 the new silc_packet_context_free function. Added also new function
5114 silc_packet_context_alloc that must be used now to allocate the
5115 context. This also means that if a routine is asynchronous from
5116 silc_[client/server]_packet_parse_type the packet context must
5117 be duplicated by calling silc_packet_context_dup. Otherwise it
5118 gets free'd after silc_[client/server]_packet_parse_type returns.
5119 Also, one must remember that if packet is duplicated then its
5120 reference count must be decresed by calling the free function as
5121 many times as it was duplicated.
5123 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5124 from both client and server.
5126 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Made joining to a channel working in router environment.
5130 * Cleaned up JOIN command on server side and create function
5131 silc_server_command_join_channel internal routine to make the
5134 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Changed silc_command_pending list to SilcDList. Also, added
5137 `ident' field to SilcServerCommandPending structure to identify
5138 the reply and to call correct callback.
5140 Added silc_server_command_pending_check function to replace the
5141 corresnponding macro. The silc_command_pending list is not
5144 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5145 to set identifier to previously allocated Command Payload. It
5146 is used to set identifier for command when resending Command
5149 * Added silc_command_payload_encode_payload to encode Command
5150 Payload buffer from SilcCommandPayload structure.
5152 * Added silc_argument_payload_encode_payload to encode Argument
5153 payload buffer from SilcArgumentPayload structure.
5155 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Changed WHOIS command to support router connection on server side.
5158 The whois request is always sent to router unless the server is
5159 standalone server. After server has received the reply from the
5160 router will it send the reply to the client.
5162 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5163 broadcast received broadcast packet. The function is used only
5164 by router. The broadcast packet is always sent to the router's
5167 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5168 render given ID to printable string, for log files for example.
5170 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Made basic router to router connections working. At least they
5173 can now connect to each other but nothing really works the way
5174 they are supposed - yet.
5176 * Added new initiator token to RouterConnection configuration
5177 file in silcd/serverconfig.[ch]. It is used to tell whether we
5178 are the initiator to the remote router or whether we'll expect
5179 the other end to connect.
5181 * Moved registering of listener task to silc_server_init, hence
5182 the server starts listenning as soon as it is run, even if it
5183 does not have connections to other routers. Let's see how well
5186 * Changed default connection retry timeouts for more suitable in
5189 * Removed cipher and such arguments from silc_idlist_add_client
5190 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5191 Added new function silc_idlist_add_data to add the keys and stuff
5194 * Added SilcIDListData structure and added it to SilcClientEntry
5195 and SilcServerEntry as their first field in the structure. This
5196 way we can explicitly cast the ID entries to the SilcIDListData
5197 structure and get common data for the entries. In past, we had
5198 to first check what type of connection it is and then cast it to
5199 correct ID entry type. Now, we can directly cast the opaque
5200 pointer to the SilcIDListData (no matter what ID entry it actually
5201 is) and get the data needed.
5203 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5206 in some circumstances even if threre were timeout tasks, though not
5207 IO tasks, but tasks anyway. Now fixed.
5209 * Defined SilcServerConnection structure to hold connection specific
5210 stuff about directly connected servers and routers. The definition
5211 is currently in silcd/server_internal.h. I thought about having
5212 a bit more important role fro this struct but for now it is used
5213 only when connecting to other server (or router actually).
5215 * Added connecting retry support in server when connecting to
5216 router(s). The retry feature implement exponential backoff
5217 algorithm. Also, added SilcServerParams structure to hold default
5218 parameters for server. For now, it include these retry settings
5219 and are hard coded. After server is moded to be as Silc Server
5220 Library this structure will be more important.
5222 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Changed client librarys channel->clients table to SilcList and
5225 changed code accordingly.
5227 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Changed client's channel table to SilcList and changed code
5230 accordingly. Also changed SilcChannelClientEntry to include back-
5231 pointer to the channel so that client entry can use that structure
5232 as list as well and we have fast cross-reference to the channel.
5233 This change dramatically decreased the complexity of channel
5234 handling with client entry and vice versa (removed one extra
5235 loop when searching for channel entry from many functions).
5237 * Changed server->sim from table to SilcDList and changed code
5240 * NAMES command can now be used from user interface. It will show
5241 the user list on the channel, neatly.
5243 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5244 Code now saves realname of the user if it becomes available.
5246 * Renamed configure.in to configure.in.pre and made ./prepare
5247 script to automatically add correct version string to
5248 configure.in which it creates from configure.in.pre.
5250 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * NAMES command reply now shows users mode with the nickname when
5255 * Moved silc_client_ch[u]mode[_char] functions from
5256 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5257 place sucks, they are utility functions and should be in some
5260 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5262 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5265 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added TRQ (efficient deque and list library) into lib/trq. This is
5270 a very good list library that is currently used in the SILC. Defined
5271 SilcList API over the library because I didn't like the API very
5272 much. See lib/trq/silclist.h for the API and examples of how to
5273 use the API. Fixed various places in the code to use the new
5274 SilcList API. The SilcList is meant for lists that has a structure
5275 already defined as a list. It is not suitable to add just some
5276 context to the list (in TRQ, the context is the list actually).
5278 So, I defined SilcDList that can be used for the purpose where
5279 predefined list structure does not exit. This can be used as
5280 such list. Now some context just can be added to the SilcDList.
5281 Currently this list is not used in the SILC just yet, though there
5282 are a lot places where this can replace dynamically allocated
5283 tables and I will fix these places, later, to use SilcDList.
5284 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5285 and use TRQ internally).
5287 Also fixed some annoying warning messages that the original TRQ
5288 code generated. Also minor changes to TRQ's Makefile.in.
5290 * Added support for querying by Client ID to both WHOIS and
5291 IDENTIFY commands into server, as required by the protocol.
5293 * Removed method function pointers from SilcBuffer structure. They
5294 weren't used to anything and just increased the context size for
5295 no good reason. This change also made silc_buffer_alloc and
5296 silc_buffer_free functions inline functions.
5298 * Disabled command flooding detection support until it's fixed so
5299 that it accepts commands in but does not execute them more than once
5302 * Added silc_net_localhost(), to return local hostname, into
5303 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5304 that must be initialized before calling silc_client_init.
5306 * Added new function: silc_server_send_notify_on_channels to send
5307 notify messages to all channels client has joined. It is assured
5308 that the message is sent only once per client.
5310 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5311 lib/silcutil/silcutil.[ch] as silc_format function. The new
5312 function is generic and is used by server as well, not only by
5313 the logging routines.
5315 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5316 the provided version string was not acceptable. Added new function:
5317 silc_ske_check_version into lib/silcske/silcske.h. The function
5318 must be implemented by the application (client or server) and it
5319 does not reside in the SKE library. The function checks the version
5320 string remote end sent.
5322 * Added back pointers (to opaque context and to SilcSocketConnection)
5323 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5325 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5326 duplicate packet context structure.
5328 * Changed `notify' client operation to send same arguments as client
5329 receives from server except for ID's. ID's are mapped to correct
5330 ID entry and that is returned. Also, if channel entry is not sent
5331 by server but the notify is for channel the channel entry is sent
5332 to application (otherwise application doesn't know that it is for
5333 channel (library gets it from packet's Destination ID)).
5335 * Added silc_client_remove_from_channels into client library to
5336 remove a client from all channels it has joined to. Used when
5337 received SIGNOFF notify from server. Added also new function
5338 silc_client_replace_from_channels to replace old ID entry with
5339 new ID entry on all channels. Used when received NICK_CHANGE
5342 * Fixed ID Cache list handling in silc_idlist_get_client in
5343 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5344 to get (or query) client by ID.
5346 * Updated TODO list.
5348 * Added connection authentication status message defined by the
5349 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5350 support for these into the code in client and server side.
5352 * Added generic function silc_client_send_command to send any command
5353 with variable argument list. Application should use this function
5354 to send commands if the command functions provided by the library
5355 does not suite for the application's user interface needs.
5357 * Added new `failure' client operation. Application is notified about
5358 received failure packet if client is executing a protocol. In this
5359 case the protocol's execution has failed.
5361 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5362 is required by the protocol.
5364 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5365 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5368 * Added status flag to SilcSKE object to indicate realtime status
5369 of the SKE protocol.
5371 * Application receives now exactly same command reply arguments as
5372 the library receives from server. However, if ID is received the
5373 corresponding ID entry is returned to the application (eg. Client
5374 ID is mapped to correct SilcClientEntry entry and that is returned).
5375 Changed command_reply client operation due to this change.
5377 * Changed all ID's in commands and in command replys as ID Payloads.
5378 Change affected both client and server side codes.
5380 All ID's sent in SILC network (with execption of ID's in SILC
5381 Packet header) are sent in ID Payload to support variable length
5384 * Server now notifies nick changes and notifies all clients on
5385 the channels about the new nickname (about the new Client ID,
5388 * Implemented CMODE command to change channel modes. Supports all
5389 channel modes defined by the protocol specs except ban and invite
5390 lists. (Also, private channel key mode is supported but support for
5391 setting private channel key in client is missing, thus, this mode
5392 has no effect on client side (except that server requires that the
5393 client uses private channel key and normal channel traffic does not
5396 Also, invite mode works per se, but INVITE command does not work
5397 yet correctly, so you can set channel as invite only channel but
5398 inviting clients to the channel does not work (it is yet to be
5399 thought what's the best way to do it).
5401 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5402 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5403 Implemented CUMODE command to change user's mode on the channel.
5404 Supports all modes defined by the protocol specs.
5406 * Added NAMES command reply to return users modes on the channel.
5408 * Removed unnecessary and slow ciphers from lib/silccrypt.
5410 * Set SO_KEEPALIVE option to connection sockets by default.
5412 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5414 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5415 redefined the Notify Payload into protocol specs.
5417 * Added silc_id_payload_parse_id to get ID directly from raw
5420 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5423 accept searching by Client ID as well.
5425 * Added support for LEAVE and SIGNOFF notify types in client library.
5427 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5428 to parse ID Payload from raw data.
5430 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Added flags parameter into silc_ske_assemble_security_properties
5433 function in lib/silcske/silcske.[ch].
5435 * Changed notify client operation to fit better for notify messages
5436 sent by server. The notify payload received from server is now
5437 passed to the application (after parsing it to SilcNotifyPayload).
5438 It is application's responsibility to retrieve the arguments
5439 from the payload and show the message the way it wants. The message
5440 sent by server is implementation specific.
5442 * Changed public keys to comply with the protocol specification.
5443 Old public keys are not supported anymore and are not compatible.
5445 * Removed nickname from Channel Payload as the latest draft removed
5446 it. The client must resolve the nickname from the NAMES command
5447 reply received when it joined the channel.
5449 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5451 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Fixed some errors in protocol specification drafts.
5455 * Created lib/silccore/silcnotify.c to implement Notify Payload
5456 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5457 generic payloads described by protocol specifications. The file
5458 includes implementations for ID Payload and Argument Payload.
5460 * Changed Command Payload implementation to use the new Argument
5461 Payload. Changed command_xxxx_payload to command_payload_xxxx
5462 to comply with SILC coding conventions.
5464 * Added suppport for Argument Payload handling in Notify Payload
5465 implementation as protocol requires it. Added the new support
5466 into server and client lib as well.
5468 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Added support for multiple nicknames on same channel. [n] is
5471 added locally to the nickname if there are more than one same
5472 nicknames on the channel.
5474 * Server now sends all nicknames that matched WHOIS request.
5475 Client also shows the list received from server.
5477 * Added TOPIC command to client side. User can now set and show
5478 current topic on channel.
5480 * Added MOTD command to client and server. Also, server sends the
5481 motd when client connects to the server.
5483 * Changed version strings to comply ISO 8601.
5485 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Fixed protocol error handling in client library. It should now
5488 cope even if the SKE fails for some reason.
5490 * Made new protocol specification drafts for submitting to IETF.
5492 * Implemented TOPIC command to server in silcd/command.c.
5494 * Added two new notify types into lib/silccore/silcnotify.h:
5495 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5496 notify nickname change and topic setting/change on a channel.
5498 * API change of command_reply operation in client library. The
5499 application gets now the status type received from server as well.
5501 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5505 * Cras fixed and optimized the packet handling even further and
5506 it should work now. Minor change to the prototype of function
5507 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5509 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Added new function into lib/silcutil/silcschedule.[ch]:
5512 silc_schedule_with_fd to select() a specified fd. The function
5513 returns after timeout expires or data arrives or goes. The
5514 function is used by packet routines to wait that all data is
5515 received from network.
5517 * Fixed data reading from network in lib/silccore/silcpacket.c.
5518 The code now assures that all data is read from the fd and then
5519 continues packet processing. This was a bug fix since the code
5520 used to drop some data in some circumstances.
5522 * Added new function into lib/silcclient/client.[ch]:
5523 silc_client_start_key_exchange to start key exchange after
5524 connection has been established to server. The code internally
5525 now uses this funtion but its main purpose was to provide it
5526 for applications that perform their own connecting. After
5527 application has created a connection it merely calls this
5528 function to start the key exchange between client and server.
5529 The library takes care of everything else after that.
5531 Updated also lib/silcclient/README to explain the usage of
5534 * Do not send to application information that connection has
5535 been established. Application gets notified it by connect
5538 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Applied cras's patch to add silc_schedule_one function. The
5541 function runs scheduler once and returns.
5543 * Fixed the scheduler after cras messed it up. The timeout
5544 handling works now as it's supposed to work.
5546 * Added into lib/silccore/ silcnotify.h to include notify
5547 message types support. Changed silc_server_send_notify*
5548 functions, in server.[ch], to support those new notify types.
5549 Added the support for the notify types into client library,
5550 as well. Added new notify client operation into ops.h in
5553 * Changed silc_server_packet_send_to_channel to send normal
5554 packets instead of just channel message packets. The function
5555 is now used to send the notify packets to channels. It is not
5556 used to send channel message packets anymore, as server never
5559 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5560 va_arg()s as it seems to require it nowadays. I guess, if SILC
5561 is compiled with older va_arg() the new code should work anyway.
5563 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Splitted core library. Core library (lib/silccore) includes
5566 now only SILC protocol specific core (and common) components.
5567 Created new utility library (lib/silcutil) that includes more
5568 generic purpose stuff. The stuff for util library was taken
5569 from the old core library. This was minor and easy split.
5571 * Created SILC Client Library (lib/silcclient) that includes
5572 implementation of the SILC client without user interface. This
5573 was major move from silc/ directory. The code has been changed
5574 so that it is transparent towards the user interface. The
5575 silc/ directory includes now the same user interface as before
5576 and it uses the new client library. Read lib/silcclient/README.
5577 Basicly, the client library performs everything else related
5578 to SILC except user interface handling. Also, configuration
5579 files are considered to be part of user interface and library
5580 does not handle them.
5582 This change also changed a lot of structures, function naming etc.
5583 Most important change was that SilcClientWindow object was
5584 renamed to SilcClientConnection in the client library. Created
5585 also new file lib/silcclient/ops.h. Also added new files
5586 silc/local_command.[ch] and silc/client_ops.[ch].
5588 All these changes were made to make it easier for user interface
5589 designers to create what ever user interface for the SILC client
5592 It is also expected that the server will be moved to lib
5593 directory as well and SILC Server Library will be created;
5594 sometimes in the future.
5596 * Removed Local commands from lib/silccore/silccommand.h as
5597 they are application specific and new client library does not
5598 handle any of those anymore.
5600 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5601 old client implementation in silc/.
5603 * Added support for callback functions in SILC_LOG_* macros.
5604 Application can now set its own callbacks that will be called
5605 instead of using the default functions that will always print
5606 the debug messages to stderr (or stdout). Also, debugging can
5607 now be disabled by setting silc_debug to FALSE and re-enabled by
5608 setting it to TRUE. Note, that logging will still work even
5609 if debugging is disabled.
5611 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5612 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5613 silc_log_reset_debug_callbacks.
5615 * To enable debugging in silc client one must give now -d
5616 option on command line.
5618 * Changed silc_schedule_init to automatically allocate task queues
5619 if they are not allocated before calling it.
5621 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Added GMP 3.1 into math library.
5625 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5628 a channel in SILC network. The packet is used by servers and
5629 routers to notify other routers that user has left a channel.
5630 This little feature was missing until now. Added the feature
5631 to protocol specification as well.
5633 Added functions: silc_server_send_remove_channel_user and
5634 silc_server_remove_channel_user into server.[ch].
5636 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5637 lib/silccore/silcpacket.h. However, they are not implemented
5640 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Fixed joining to a channel and sending channel messages
5643 between server and router. The channel message sending should
5644 now work inside a cell.
5646 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Fixed the private message sending between server and router.
5649 The private message sending should now work inside a cell.
5651 * Added silc_server_replace_id into server.[ch] to replace
5652 existing ID in the SILC network.
5654 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5655 and silc_idlist_replace_server_id into idlist.[ch] in server.
5657 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Fixed the server to server connections. Server can again now
5660 connect to router. Router to router connections probably does
5663 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Added dynamic protocol registering support. Now protocols can
5666 registered and unregistered on the fly. Patch by cras.
5668 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Added lib/contrib directory to hold routines that some platforms
5671 don't have but are needed by SILC.
5673 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5674 into lin/contrib to provide getopt() and getopt_long() for
5675 those who don't have it.
5677 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Added AWAY command to client. When away message is set and
5680 client receives a private message packet the client automatically
5681 replies to the sender with the away message.
5683 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5684 bug seemed to be the cause of recent problems when compiling
5687 * Added version detection support to SKE protocol specification
5688 and added the new changes to the SKE implementation as well.
5689 There were other minor changes in the SKE protocol as well.
5691 Many changes in lib/silcske/silcske.[ch] and in
5692 lib/silcske/payload.[ch].
5694 * Added ^U functionality, clear input line. Patch from cras.
5696 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Mainly small bugfixes on core library. Fixed some debugging
5699 logging and buffer overflow in silclog.c.
5701 * Updated config.sub and config.guess on the distribution tree.
5703 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Added command lagging support in server. Client may execute
5706 commands now only once in two seconds.
5708 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Optimized packet reception. MAC computation and checking is now
5711 also more optimized. A lot previously duplicated code is now
5712 used as generic by both client and server.
5714 * Fixed key pair generation in clientutil.c
5716 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Added into lib/silccore/silcbufutil.[ch] new function;
5719 silc_buffer_realloc.
5721 * Moved generic packet sending/encryption functions to
5722 lib/silccore/silcpacket.[ch] from client and server. Some
5723 rewriting of the functions.
5725 * Moved all generic packet reception/decryption functions to
5726 lib/silccore/silcpacket.[ch] from client and server. The
5727 packet processing is now much cleaner in both client and server.
5728 These were major changes in both client and server.
5730 * Created many common functions in server to do packet sending.
5731 Previously code were duplicated a lot, this has been removed
5734 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Rewrote major parts of the ID cache system. Don't know
5737 whether it is better now or not but at least the API is more
5740 * Major rewrite on ID cache stuff on client because of the ID
5741 cache API changes. Added idlist.c to client.
5743 * Also major rewrite on ID cache stuff on server as well.
5744 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5745 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5746 in hand, instead they are all put into the ID cache system now.
5747 All server_idlist_* routines uses ID cache now instead of
5748 traversing its own lists (those lists does not exist anymore).
5749 SilcIDList though still exists. Also, SilcXXXEntry's are
5752 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Finally made the SKE implementation compliant to the protocol
5755 specification. All mp integers are now binary encoded as
5756 opposed being HEX encoded.
5758 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5761 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5762 functions: silc_[encode/decode]_pem. Also added function
5763 silc_encode_pem_file to PEM encode with newlines ('\n') for
5766 * SILC public keys are now encoded either PEM or binary. Same
5767 option is for private keys as well. By default private keys
5768 are binary encoded and public keys PEM encoded. Silly HEX
5769 encoding were removed.
5771 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5772 function to create fingerprints.
5774 * Fixed a bug in SHA1; does not change the original data anymore.
5776 * Partly implemented INFO command on client and server side.
5777 Fixed CLEAR command. Changes to SERVER command; show current
5778 server(s) when giving command without arguments. Added
5779 VERSION command to client.
5781 * Added check to server that unregistered connections cannot
5782 execute commands (unless it is specificly allowed).
5784 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Fixed screen refresh.
5788 * Fixed channel joining bug from client. On some circumstances
5789 client tried to join to a channel it had already joined.
5791 * Added public key verification process into client's protocol.c.
5792 The client now verifies the public key from user and saves
5793 it into ~./silc/serverkeys/ directory.
5795 Added into: clientutil.[ch]: silc_client_verify_server_key.
5797 * Changed SKE protocol's silc_ske_initiator_finish function
5798 to accept callback function that verifies the received public
5799 key. Removed old silc_ske_verify_public_key function.
5801 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5804 silc_pkcs_private_key[_data]_set.
5806 * Made the password and public authentication more cleaner in
5807 server's protocol.c.
5809 * Removed historic and obsolete protocol `channel_auth' from
5810 both client and server.
5812 * Removed wrong way of sending command status messages from
5813 server to client in server's command.c. The old way violated
5814 protocol specification.
5816 Changes to silccore/silccommand.[ch]: removed
5817 silc_command_encode_status_payload -> not needed anymore,
5818 changed silc_command_encode_payload_va to accept extra
5819 argument on variable argument list. The argument type must
5820 now be provided to the function. Also, added new function:
5821 silc_command_encode_reply_payload_va which is same as
5822 normal command_encode_payload_va except command status type
5823 is provided as extra argument.
5825 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Added ~./silc directory handling. The directory includes the
5828 public and private keys for the client.
5830 Added silc_client_check_silc_dir, silc_client_create_identifier
5831 and silc_client_load_keys.
5833 * Implemented SILC protocol compliant public key. Added public
5834 and private key saving to and loading from files.
5836 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5837 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5838 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5839 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5840 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5842 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5843 silc_pkcs_load_[public/private]_key.
5845 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Added silc_server_get_route (route.[ch]) to get connection
5848 data for the fastest route for given ID.
5850 * Implemented INVITE command on client and server. The command
5851 were re-defined in the SILC Protocol Specification and the
5852 implementation now complies with the specification.
5854 * Implemented PING command on client and server.
5856 * Implemented NAMES command on client and server. The server side
5857 supports currently only normal server not router server yet.
5858 Some changes to NAMES definition in SILC protocol specification.
5860 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Implemented LEAVE command on client and server.
5864 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5865 again. This change was made to the protocol as well. Server
5866 should not violate the protocol specification anymore.
5868 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5871 was tested. SOCKS4 was not but should work anyway.
