1 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed CMODE command when new channel key was created. If
4 the creation failed the old key was removed. Next time giving
5 same command would crash the server since the old key was
6 freed already. Affected file silcd/command.c.
8 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Added silc_log_set_debug_string function to set a regex
11 string to match for debug output. Only the function names,
12 or filenames matching the given debug string is actually
13 printed. This way it is possible to filter out those debug
14 strings that user is not interested in.
16 Fixed a bug in silc_string_regexify.
18 Affected files lib/silcutil/silclog.[ch], and
19 lib/silcutil/unix/silcunixutil.c.
21 * Changed the -d options in both server and Irssi SILC client
22 to take the debug string as argument. Affected files
23 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
25 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
27 * Added silc_hash_babbleprint to create a Bubble Babble
28 Encoded fingerprint. The encoding is developed by Antti
29 Huima (draft-huima-babble-01.txt), and it creates human
30 readable strings out of binary data. Affected file
31 lib/silccrypt/silchash.[ch].
33 * Print the babble print now in addition of fingerprint as well
34 in Irssi SILC client. Affected files are
35 irssi/src/fe-common/silc/module-formats.[ch],
36 irssi/src/fe-common/silc/core/client_ops.c.
38 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
40 * Fixed a security problem found in SKE. The initiator's
41 public key too is now added to the HASH hash value creation
42 which is signed by the responder to create the SIGN value.
43 This will prevent anyone in the middle to lie to the responder
44 about the initiator's public key. If this is done now, the
45 man in the middle will get caught. Updated the protocol
48 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
50 * Better installation directory handling. Configure module
51 paths and other paths automatically to example_silc* files
52 in doc/. A patch by toma.
54 * Fixed compiler warning from MPI library, and from SILC RNG.
57 * Added SILC_SERVER_PID_FILE to define the pid file for server.
58 It can be configured with ./configure. A patch by toma.
60 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
62 * Find correct make to use in prepare-clean. A patch by
63 toma. Affected file prepare-clean.
65 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>

79 lib/silcclient/client_keyagr.c
82 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
84 * Added silc_pkcs_public_key_compare to compare two
85 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
87 * Check that the client who set the founder mode on the
88 channel is the same client that is giving the founder
89 mode to itself. It is done by comparing the saved public
90 key (it is saved even in the authentication is passphrase).
91 Affected file silcd/command.c.
93 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
95 * Do not process packet for disconnected socket connection.
96 Affected file lib/silccore/silcpacket.c.
98 * Process the DISCONNECT packet through scheduler in the
99 client library. Affected file lib/silcclient/client.c.
101 * Fixed the silc_client_packet_parse to not to increase
102 the packet sequence number if the conn->sock and the
103 current socket connection is not same. This can happen
104 for example during key agreement when the conn includes
105 multiple socket connections (listeners). Affected file
106 lib/silcclient/client.c.
108 * The sender of the file transfer request now provides also
109 the pointer (listener) for the key exchange protocol. If
110 the listener cannot be created then it sends empty key
111 agreement and lets the receiver provide the listener.
113 Added `local_ip' and `local_port' arguments to the
114 silc_client_file_send. If they are provided they are used,
115 if not then it will attempt to find local IP address, if
116 not found or bind fails then the remote client will provide
119 Affected files are lib/silcclient/client_ftp.c and
120 lib/silcclient/silcapi.h.
122 * Extended the FILE SEND command to support defining the
123 local IP and port for key exchange listener. They are
124 optional. Affected file irssi/src/silc/core/silc-servers.c.

128 * Defined to WHOIS command reply the sending of fingerprint
129 of the client's public key (if the proof of posession of the
130 corresponding private key is verified by the server).
131 Updated to the protocol specification.
133 * Added support of receiving the client's public key's
134 fingerprint in command reply in client library. Affected
135 file is lib/silcclient/command_reply.c, and
136 lib/silcclient/idlist.[ch].
138 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

146 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
148 * Assure that silc_server_close_connection cannot be called
149 twice for same socket context. Affected file is
152 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
154 * Send error message to application if opening file for
155 writing during file transfer fails. Affected file is
156 lib/silcclient/client_ftp.c.
158 Remove all file transfer sessions for a client that we're
159 removing from ID cache.
161 Affected file is lib/silcclient/client_ftp.c.

191 client library. Affected file lib/silcclient/client_prvmsg.c.
193 * Do not actually remove the client directly from ID cache
194 during SERVER_SIGNOFF, but invalidate it. This way we
195 preserve the WHOWAS info for the client. Affected file
198 * Fixed SERVER_SIGNOFF notify handling in the server. The
199 server is now able to process incoming SERVER_SIGNOFF notify
200 for a server that it doesn't even know about. It will remove
201 the clients provided in the notify. Affected file
202 silcd/packet_receive.c.
204 * Check for partial packet in data queue after every packet that
205 was found from the queue. Return and wait for more data if
206 there is partial data in queue. Affected file is
207 lib/silccore/silcpacket.c.
209 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

217 * Check that newsize in silc_buffer_realloc is larger than
218 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
220 * Added better monitor of file transfers. It now monitors
221 key agreement protocol during the file transfer too. Added
222 error reporting too. Affected files
223 irssi/src/silc/core/silc-servers.c,
224 irssi/src/fe-common/silc/module-formats.[ch].
226 * Wrote a help file for FILE command.
228 * Added silc_rng_global_get_byte_fast to get not-so-secure
229 random data as fast as possible. Random data is read from
230 /dev/urandom if available and from the SILC RNG if not
231 available. It is used in padding generation. Affected file
232 lib/silccrypt/silcrng.[ch].
234 * All packets in client library are now processed synchronously.
235 Optimized packet processing a lot. Affected file
236 lib/silcclient/client.c.
238 * All server connection packets are processing synchronously
239 now in server, to optimize packet processing. Affected file
242 * Include files are installed now only in Toolkit distribution
243 if make install is given. Affected files: all Makefile.am's.
245 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
247 * Assure that silc_client_notify_by_server_resolve does not
248 resolve the client information multiple times. If it cannot
249 be found by the first it cannot be found at all. Affected
250 file lib/silcclient/client_notify.c.
252 * Fixed WHOWAS command reply calling. Affected file
253 lib/silcclient/command_reply.c.
255 * Removed all references to silc_idlist_get_client from the
256 Irssi SILC client since that call is internal call used by
257 the library. The Irssi SILC client will use now client
258 retrieval functions found in silcapi.h.
260 * Fixed a bug in resolving nickname info before sending
261 private message. It used freed memory. Affected file
262 irssi/src/silc/core/silc-servers.c.
264 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

283 * Added silc_net_localip to return local host's IP address.
284 Affected file lib/silcutil/silcnet.[ch].
286 * If key exchange or rekey protocol is active for a connection
287 parse all packets syncronously since there might be packets
288 in packet queue that we are not able to process without first
289 processing packets before them. Affected file silcd/server,
290 lib/silcclient/client.c.
292 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
293 whether library should continue processing the packet.
294 Affected file lib/silccore/silcpacket.h.

327 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
329 * Resolve the client info when received private message or
330 channel message for a client which nickname we don't know.
331 Affected files lib/silcclient/client_prvmsg.c and
332 lib/silcclient/client_channel.c.
334 * Do not crash in /KEY if client is not connected. Affected
335 file irssi/src/silc/core/silc-channels.c.
337 * Added SilcClientStatus field to the SilcClientEntry in the
338 lib/silcclient/idlist.h.
340 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
341 is incomplete and is being resolved, it won't be resolved
344 Make sure also that USERS command reply does not resolve
345 twice information. Affected file is
346 lib/silcclient/command_reply.c.
348 Make sure that silc_client_get_clients_by_list does not
349 resolve twice same information.
351 * Check for valid client->id in the silc_server_free_client_data.
352 Affected file silcd/server.c.
354 * Fixed /GETKEY nick@server not to crash if the server entry

367 * Call the silc_server_udpate_servers_by_server in the
368 primary router that comes back online in the backup resuming
369 protocol. Otherwise it routes packets wrong. Affected file
370 silcd/server_util.[ch], silcd/server_backup.c.
372 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
374 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
375 lib/silcutil/silcbuffmt.[ch].
377 * Redefined the SILC packet header to include the padding
378 length. Affected file lib/silccore/silcpacket.[ch].
380 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
381 length for maximum padding up to 128 bytes). Affected
382 file lib/silccore/silcpacket.h.
384 * Removed all backwards support for old 0.5.x MAC thingies.
385 The SILC packet header change makes it impossible to be
386 backwards compatible.
388 * Send the ENDING packet with timeout in the backup resuming
389 protocol. This is to assure that all routers has connected
390 to the primary router. Affected file silcd/server_backup.c.
392 * Changed the RNG to take the first IV from random data. It
393 used to take it from zero actually. Changed the RNG also
394 to use /dev/urandom during session. /dev/random is used
395 in initialization. Affected file lib/silccrypt/silcrng.[ch].
397 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
399 * Changed the SILC packet header to have the first two bytes
400 (the packet length) encrypted. Affected files aroung the
401 code tree, lib/silccore/silcpacket.[ch]. Removed the
402 SilcPacketCheckDecrypt callback. It is not needed anymore
403 since the silc_packet_receive_process will determine now
404 whether the packet is normal or special.
406 * Implemented the unidirectional MAC keys. Affected files
407 lib/silcske/silcske.c, silcd/protocol.c and
408 lib/silcclient/protocol.c.

415 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
417 * Allow backup router to announce servers. All servers
418 announced by backup router are added to the global list
419 automatically. Update hte server's socket to our primary
420 router also when backup router announces a server.
421 Affected file silcd/packet_receive.c.
423 * Do not update the client->router in the function
424 silc_server_udpate_clients_by_server if the client is on
425 global list. We might fail to find any specific server
426 for locally connected clients and local cell clients. They
427 should still use the `from' and not `to' as client->router.
428 This fixes backup router resuming protocol. Affected file
431 * Decrease channel statistics count only if the channel
432 deletion worked. Affected files are silcd/server.c and
435 * Added silc_server_update_servers_by_server to update origin
436 of all server entries. Used during backup router protocol.
437 Affected files silcd/server_util.[ch], silcd/server.c. and
438 silcd/backup_router.c.

442 silc_hmac_get_hash and silc_hmac_get_name. Affected file
443 lib/silccrypt/silchmac.c.
445 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
447 * Assure that router cannot reroute the same channel message
448 to the sender. Affected file silcd/packet_receive.c.
450 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Made better checks that the channel message is not sent
453 to the router it came from. Affected file is
454 silcd/packet_send.c. Fixed memory leak too.
456 * Announce informations for incoming router connection, but
457 only after checking if it is replaced by backup router.
458 Affected file silcd/packet_receive.c.
460 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
462 * Fixed the backup resuming protocol to work in multiple
463 router environment. Affected file silcd/server_backup.c.
465 * Route packet only to one router in the function
466 silc_server_packet_send_to_channel. Affected file is
469 * Fixed silc_server_send_notify_dest to set the broadcast
470 flag. Fixed the silc_server_send_notify_topic to actually
471 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
472 Affected file silcd/packet_send.c.
474 * Changed the SFTP Filesystem interface. Changed the
475 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
476 the filesystem operation function. The SilcSFTPFilesystem
477 is now a context that is allocated by all filesystem allocation
478 functions and it already includes the operations structure
479 and filesystem specific context. It is given as argument
480 now to the silc_sftp_server_start. This made the interface
481 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
482 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
484 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
486 * Changed the backup router adding and getting interfaces
487 in the server. The router that will be replaced by the
488 specified backup router is now sent as argument. Affected
489 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
492 * Added silc_net_addr2bin_ne to return the binary form of
493 the IP address in network byte order. Affected files
494 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].

504 in upstream or downstream. Affected file is
507 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
509 * Wrote the definition of the backup resuming protocol to the
510 protocol specification.
512 * Removed one redundant channel key generation from normal
513 server during joining procedure. Removed one redundant
514 channel key sending from server to router during joining
515 procedure. Affected file silcd/command.c.
517 * Made minor bugfixes to the backup router resuming protocol.
518 Affected file silcd/server_backup.c, server.c.
520 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

527 resume the primary router position in the cell after the
528 primary router comes back online. Affected files
529 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
530 and silcd/server_util.[ch].
532 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
534 * Sleep two (2) seconds after sending QUIT command to server.
535 Affected file lib/silcclient/command.c.
537 * Assure that if outgoing data buffer is pending do not force
538 send any data. Affected file silcd/packet_send.c.
540 * Assure that if outgoing data buffer is pending do not force
541 send any data. Affected file lib/silcclient/client.c.
543 * Implemented the backup router support when the primary router
544 goes down. The servers and routers can now use the backup
545 router as new primary router without loosing connectivity.
547 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
550 in the server to indicate disabled entry. All data read
551 from the connection will be ignored and no data is sent
552 for entry that is disabled. Affected files are
553 silcd/idlist.h, silcd/server.c.
555 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Created SFTP client and server test programs in the
558 lib/silcsftp/tests directory.
560 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
562 * Implemented memory filesystem (virtual filesystem) for
563 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
566 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Implemented the SFTP (SSH File Transfer Protocol) to the
569 lib/silcsftp. It includes SFTP client and SFTP server
572 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Moved lib/silccore/silcprotocol.[ch] to the
575 lib/silcutil library.
577 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
578 take variable argument list pointer as argument. Affected
579 file lib/silcutil/silcbuffmt.[ch].
581 * Added silc_buffer_set function that is used to set data
582 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
583 Affected file lib/silcutil/silcbuffer.h.
585 * Changed various routines in the core library to use the new
586 silc_buffer_set instead of allocating new buffer only for
589 * Added 64-bit value formatting and unformatting support to the
590 silc_buffer_[un]format routines. Affected file is
591 lib/silcutil/silcbuffmt.[ch].
593 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
594 to includes/bitmove.h.
596 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Fixed channel user mode saving in client library. Affected
599 file lib/silcclient/command[_reply].c.
601 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Defined the file transfer to the SILC Protocol. Added
604 new packet type SILC_PACKET_FTP and defined File Transfer
605 Payload. The mandatory file transfer protocol is SFTP
606 (SSH File Transfer Protocol). Affected file in addition
607 of the internet draft is lib/silccore/silcpacket.h.
609 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
610 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
611 is used as part of backup router protocol when the primary
612 router of the cell is back online and wishes to resume
613 the position as primary router.
615 * Redefined the MAC generation keys in the protocol. The
616 same key is not used anymore in both direction. Both
617 direction will now use different keys for sending and
618 receiving. This fixes a potential security flaw. This
619 change causes incompatibilities in the protocol.
621 * Redefined also the MAC computation from the packet.
622 An packet sequence number is now added to the MAC
623 computation. This prevents possible replay attacks against
624 the protocol. This change too causes incompatibilities
627 Added `sequence' field to the SilcPacketContext to hold
628 the current sequence number for the packet.
630 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Added `created' field to the SilcIDListData in the file
633 silcd/idlist.h to indicate the time when the entry was
636 * Added `created' field to the SilcChannelEntry too. Affected
639 * Added `creation_time' aguments to all the announcement functions
640 in the server. If it is provided then only the entries that
641 was created after the provided time frame are actually
642 announced. Affected file silcd/server.[ch].
644 * The protocol says that the Channel ID's IP address must be
645 based on the router's IP address. Added check for this in
646 the silc_server_new_channel when processing incoming New Channel
647 Payload. Affected file silcd/packet_receive.c.
649 * Print out the correct version with --version in SILC client.
650 Affected file irssi/src/silc/core/silc-core.c.
652 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
654 * Fixed WHOWAS command to check for completnes of the client
655 entry always, not just when the command is coming from client.
656 Affected file silcd/command.c.
658 * Added new function silc_server_packet_queue_purge to purge the
659 outgoing data queue to the network. After the function returns
660 it is guaranteed that the outgoing packet queue is empty.
661 Affected file silcd/packet_send.[ch].
663 * Purge the outgoing packet queue in the rekey protocol's final
664 callback to assure that all rekey packets go to the network
665 before quitting the protocol. Affected file silcd/server.c.
667 * Added silc_client_packet_queue_parse as similar function as
668 in server to the client library. The affected file is
669 lib/silcclient/client.c.
671 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
673 * Splitted silcd/server.c and created silcd/server_util.[ch]
674 for utility functions.
676 * Added new socket flag SILC_SF_DISABLED to indicate that the
677 connection is open but nothing can be sent to or received from
678 the connection. Affected file lib/silcutil/silsockconn.[ch].
679 The checking for disabled socket is checked in the low level
680 silc_socket_write and silc_socket_read functions.
682 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Allow only nicknames and channel names that fits into the
685 7-bit unsigned char ASCII set. Affected file silcd/command.c.
687 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
689 * When processing JOIN command reply in server check that if
690 the channel exists in our global list we'll move it the local
691 list. Affected file silcd/command_reply.c.
693 * Fixed the check whether client is joined on the channel already
694 in JOIN command. Affected file lib/silcclient/command.c.
696 * Fixed the JOIN command reply to check whether the channel
697 already exists. Affected file lib/silcclient/command_reply.c.
699 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
701 * Added silc_ske_status_string to map the SKE error numbers
702 to readable strings. The affected files are
703 lib/silcske/silcske[_status].[ch].
705 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Do not show the private channels on the WHOIS channel list
708 as it is not allowed by the protocol. The affected file is
711 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
713 * Assure that the packet length digged from the actual packet
714 is something sensible in the silc_packet_decrypt_rest_special
715 in lib/silccrypt/silcpacket.c.
717 * Free and NULL the allocated pointer in silc_hmac_alloc if
718 the HMAC allocation fails. The affected file is
719 lib/silccrypt/silchmac.c.
721 * Print the selected security properties to the log files in
722 the server. Affected file silcd/protocol.c.
724 * Add SKE's reference counter even if calling the completion
725 callback manually. Otherwise it goes negative, although it
726 does not cause any problems. The affected file is
727 lib/silcske/silcske.c.
729 * Remove the client entry with short timeout after giving the
730 KILL command. Affected file lib/silcclient/command.c.
732 * Fixed to send error reply in WHOIS and IDENTIFY commands in
733 case all found clients are already disconnected (WHOWAS would
734 found them) in the server. Affected file silcd/command.c.
736 * Update the last_receive (time of last data received) to be
737 updated only when received private or channel message so that
738 the idle time showed in WHOIS makes more sense.
740 * Added boolean field `valid' in to the SilcClientEntry in the
741 client library to indicate whether the entry is valid or not.
742 This fixes the nickname change bug on channel when changing
743 the nickname to be same than the old (like nick to Nick) the
744 nickname formatter doesn't set the new nick anymore to Nick@host.
745 Affected file lib/silcclient/idlist.[ch].
747 * Now actually fixed the nickname changing on disconnection.
748 Added new function silc_change_nick to the Irssi SILC Client.
749 Affected file irssi/src/silc/core/client_ops.c,
750 irssi/src/silc/core/silc-nicklist.[ch].
752 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
754 * Check that the public key exists in the GETKEY command before
755 trying to encode it. Affected file silcd/command.c.
757 * Print some notifications on received public keys with GETKEY
758 command in the Irssi SILC Client. Affected files are
759 irssi/src/fe-common/silc/module-formats.[ch],
760 irssi/src/silc/core/client_ops.c.
762 * Use IDENTIFY command to resolve the server information in the
763 GETKEY command instead of INFO command. Affected file
764 lib/silcclient/command.c.
766 * All command reply functions in the client library now calls
767 the pending command reply callbacks even if an error has
768 occurred. The server has done this a long time and now it was
769 time to move the client library to this as well. Now all
770 errors can be delivered back to the pending command reply
771 callbacks if necessary. Affected files are
772 lib/silcclient/command[_reply].[ch].
774 * Change the nickname on disconnection back to the username
775 because in reconnect the server will enforce it to it anyway.
776 Affected file irssi/src/silc/core/silc-servers.c.
778 * Fixed a config file parsing bug in the Irssi SILC client.
779 Affected file irssi/src/silc/core/clientconfig.c.
781 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * When printing the channel mode on JOIN, verify that the
784 channel key and channel's HMAC are valid. Affected file
785 irssi/src/silc/core/client_ops.c.
787 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
790 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
791 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
793 * Removed channel key rekey task deleting from the function
794 silc_server_save_channel_key. Affected file silcd/server.c.
795 Added explicit timeout task context instead that is used to
796 delete the task if we are registering a new task before the
797 new task has elapsed.
799 * When channel key rekey occurs the client library now saves
800 the old channel key for a short period of time (10 seconds) and
801 is able to use it in case some is still sending channel
802 messages encrypted with the old key after the rekey. Affected
803 file lib/silcclient/[idlist.h|client_channel.c].
805 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Added check to the silc_server_new_id_real to not accept
808 new ID if it is the sender's own ID. Affected file is
809 silcd/packet_receive.c.
811 * Assure that we do not announce ourself or the one we've
812 sending our announcements when we're router and are announcing
813 servers to our primary router. Affected file silcd/server.c.
815 * Fixed silc_server_command_identify_check_client to assemble
816 correct WHOIS packet. It send corrupted WHOIS packet and
817 caused problem with router to router connections. Affected
818 file silcd/command.c.
820 Fixed also silc_server_command_whois_check the same way
821 as for the IDENTIFY command.
823 * Added new SilcIDListStatus to the server in the SilcIDListData
824 structure. The status now includes the current status of
825 the entry (like registered, resolved etc.). Affected file
826 silcd/idlist.[ch]. Defined a bunch of different status types
827 as well. This replaced the old boolean registered field as well.
829 Added resolve_cmd_ident field to the SilcClientEntry structure
830 too so that if the entry is for example being resolved so
831 another command may attach to the same pending command reply
832 without requiring to resolve the same entry again. This concept
833 should optimize the WHOIS and the IDENTIFY resolving under
834 heavy load by taking away unnecessary resolving for entries
835 that are being resolved already.
837 Added support for adding multiple pending commands for one
838 command idenfier. Affected file silcd/command[_reply].[ch].
840 * Fixed WHOIS and IDENTIFY save to remove the cache entry
841 before deleting the data. Otherwise the hash table will have
842 freed data in comparison functions. Affected file is
843 silcd/command_reply.c.
845 * Fixed silc_idlist_replace_client_id to add the new entry to
846 the cache with NULL nickname. Otherwise there will be invalid
847 memory as the nickname after the nickname is freed. Affected
848 file silcd/packet_receive.c.
850 * Fixed the silc_idlist_get_clients_by_hash. The entries was
851 saved into wrong slots because the previous number of entries
852 was not taken into account. Affected file silcd/idlist.c.
853 Fixed same thing in silc_idlist_get_clients_by_nickname too.
855 * If we are router and we receive JOIN notify to a channel that
856 does not have any users then notified client is marked as the
857 channel founder, as it is it. The affected file is
858 silcd/packet_receive.c
860 * Added to the extended hash table API's table_del_*ext functions
861 the destructor as argument too, so that the caller can decide
862 which destructor to use or whether to use destructor at all.
863 Affected file lib/silcutil/silchashtable.[ch].
865 * Fixed ID Cache purging. It actually deleted the entries from
866 the hash table after the data was freed. The hash table ended
867 up comparing freed memory. The affected file is
868 lib/silccore/silcidcache.c.
870 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
872 * Fixed Irssi SILC client's KILL command's HELP syntax.
874 * The USERS command now resolves the detailed user information
875 if the userinfo field is missing. Affected file is
876 lib/silcclient/command_reply.c.
878 * Do not print error in silc_file_read if the read file does
879 not exist. Just silently return NULL. Affected file is
880 lib/silcutil/silcutil.c.
882 * Fixed the silc_log_output to not wine about NULL filename
883 and to not create some bogus " " filename. Affected file is
884 lib/silcutil/silclog.c.
886 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Fixed various printing bugs on the user interface in the
889 Irssi SILC Client. Minor changes that were forgotten from
892 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Fixed the configure.in.pre and the compilation and distribution
895 environment to support the new autoconf 2.52. That version is
896 now required to compile the CVS trunk.
898 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Renamed function silc_parse_nickname to silc_parse_userfqdn
901 to generally parse user@fqdn format strings. Affected file
902 lib/silcutil/silcutil.c.
904 * Added nickname_format and nickname_force_format fields to the
905 SilcClientParams structure. The first one defines the format
906 for the nicknames that the library will enforce if the receives
907 multiple same nicknames. The second one is boolean value and
908 can be used to force the library to always enforce the format
909 to the nicknames regardles whether there are multiple nicknames
910 or not. This configurable formatting was employed to flexibly
911 support accessing multiple nicknames from the user interface.
912 The userinterface can now set the nicknames to what ever format
913 they prefer. Affected file lib/silcclient/silcapi.h.
915 Added function silc_client_nickname_format to the file
916 lib/silcclient/idlist.c. It performs the nickname formatting.
918 Added new field `hostname´ to the SilcClientEntry context.
919 It holds the hostname of the client. Affected file is
920 lib/silcclient/idlist.h.
922 * Irssi SILC Client sets the nicknames in nick@hostn format.
923 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
924 irssi/src/silc/core/silc-core.c.
926 The WHOIS printing now also shows both the real nickname and
927 the formatted nickname so that user knows how to access the
928 user if there are multiple same nicknames cached. Affected
929 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
930 printing formatting too to take the hostname now as a separate
931 argument. The Affected file is
932 irssi/src/fe-common/silc/modules-formats.[ch].
934 * Changed the silc_client_get_clients_local to accept the formatted
935 nickname as argument. It accepts the real nickname too but the
936 formatted nickname can be used to find the true entry from
937 multiple entries. Affected file lib/silcclient/silcapi.h and
938 lib/silcclient/idlist.c.
940 * Added nickname_format_parse field to the SilcClientParams.
941 It is a callback function provided by the application to parse
942 the nickname out of the formatted nickname string. The library
943 calls it to get the nickname from the formatted string. Since
944 the application generally knows better the format of the nickname
945 string it parses it instead of the library, even though library
946 encodes the formatted string. If the callback function is not
947 provided then the library will use the string as is. The
948 affected file is lib/silcclient/silcapi.h.
950 * All the nickname strings passed to the client library in
951 commands are now expected to be formatted nickname strings.
952 If the command does not support the formatted nickname string
953 it will assume that the sent string is the actual nickname.
954 Affected file lib/silcclient/command.c.
956 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Added public key authentication support to OPER and SILCOPER
959 commands in the client library. Affected file is
960 lib/silcclient/command.c.
962 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Changed the get_auth_methdod client operation to be asynchronous.
965 It can be async if the application resolves the authentication
966 method from the server during the negotiation. Added new
967 SilcGetAuthMeth completion callback that the application will
968 call after resolving the authentication method.
970 Added function silc_client_request_authentication_method that
971 the application can use to resolve the authentication method
972 from the server. Added also SilcConnectionAuthRequest callback
973 that the library will call after the server has replied. The
974 application can call this function if it does not know the
975 current authentication method.
977 Affected files are lib/silcclient/client.c and
978 lib/silcclient/silcapi.h.
980 * The Irssi SILC client now automatically resolves the authentication
981 method incase any configuration information is not present (and
982 currently there never is). The affected file is
983 irssi/src/silc/core/client_ops.c.
985 * Fixed public key authentication from the client library.
986 Affected file lib/silcclient/protocol.c. Changed also the
987 protocol specification about the public key authentication in
988 the connection authentication protocol. The actual data to be
989 signed is now computed with a hash function before signing.
991 * Fixed the public key authentication from the server as well.
992 Affected file silcd/protocol.c.
994 * Removed the mlock()'s from the memory allocation routines.
995 Affected file lib/silcutil/silcmemory.c. The ./configure does
996 not check anymore for the mlock(). Affected file is
999 * Fixed USERS command in server to allow the execution of the
1000 command for private and secret channels if the client sending
1001 the command is on the channel. Affected file silcd/command.c.
1003 * Fixed silc_client_get_clients_local to return the clients
1004 count correctly. It could return wrong value. Affected file
1005 lib/silcclient/idlist.c.
1007 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1010 types. The assembler optimizations seemed not to like 64-bit
1011 data types. The assmebler optimizations thus are now enabled
1012 also for BSD systems as opposed to only enable them for Linux.
1014 * Do not check for threads at all on BSD systems. Affected
1015 file configure.in.pre.
1017 * Removed -n and -h options from the Irssi SILC Client since
1018 they are not used in silc.
1020 * Fixed the prime generation to assure that the first digit
1021 of the generated random number is not zero since our conversion
1022 routines does not like number strings that starts with zero
1023 digit. If zero digit is seen the random number is regenerated.
1024 This caused some corrupted RSA keys when the zero first digit
1025 was met. Affected file lib/silcmath/silcprimegen.c.
1027 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Fixed WIN32 configuration in the ./configure script.
1030 Fixed to include xti.h on environments that has it.
1031 Patches by Carsten Ilchmann and andrew.
1033 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * Changed the silc_id_create_client_id to be collision
1036 resistant. It is now assured that there cannot be created
1037 two same client ID's. I suspect that some weird bugs in
1038 the server were actually caused by duplicate Client IDs.
1039 Affected file silcd/serverid.[ch]. A router receiving
1040 new ID now also assures and informs the sending server
1041 if the ID caused collision.
1043 * Changed the silc_id_create_channel_id to also assure that
1044 there are no collisions.
1046 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Statement about ignoring the Mutual Authentication flag when
1049 performing rekey with PFS was a bit misleading. It is ignored
1050 if it was set in the initial negotiation, it cannot be even
1051 set in the rekey. Fixed in the ke-auth draft. Started the
1052 new versions of the protocol drafts in the doc/.
1054 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Fixed a bug in silc_client_command_identify_save when saving
1057 new channel information. The channel name was no duplicated
1058 and caused crash on exit. Affected file is
1059 lib/silcclient/command_reply.c.
1061 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * Fixed the getkey command handling in the server. Send just
1064 empty OK reply to the sender if the key could not be fetched
1065 (but everything else was ok, like the key just was not available).
1066 Changed the public key parameter to optional in the protocol
1067 specs so that empty OK reply can be sent. Affected file
1070 Added a message to Irssi SILC client to tell to user if the
1071 server did not return a public key.
1073 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1075 * Fixed a channel key regeneration bug. It registered new
1076 timeout tasks exponentially until all system resources were
1077 used. Affected file silcd/server.c.
1079 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Added the SILC Document generator to the scripts/silcdoc.
1082 It can be used to generate the Toolkit Reference Manual out
1083 of the source tree. Internally it will also use the RoboDoc
1084 generator now imported in util/robodoc.
1086 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Added couple of return's in rekey protocol if error orccurred
1089 during the protocol. The execution must be terminated.
1090 Affected file silcd/protocol.c. Also, terminate the protocol
1091 always with timeout.
1093 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * The client's Client ID was created initally from the wrong
1096 nickname (it could have been in format nick@host) in the
1097 silc_server_new_client. Affected file silcd/packet_receive.c
1099 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Added some SILC_LOG_ERROR's to various error conditions
1102 if client could not be added to ID cache. Affected files
1103 silcd/packet_receive.c and silcd/server.c.
1105 * When client's sock->user_data is freed, NULL also the
1106 client->router and client->connection pointers. Added check
1107 for these pointers being NULL to various places around the
1108 code. Affected file silcd/server.c.
1110 * Added client->data.registered == TRUE checks to various
1111 places around the code to assure that unregistered client's
1112 are not handled when it is not allowed. Affected file
1115 * Added `bool registered' fields to all
1116 silc_idlist_[server|client]_get_* routines to indicate whether
1117 the fetched client needs to be registered or not. Affected
1118 file silcd/idlist.[ch].
1120 * Add your own entry as registered to the ID cache in the
1121 server. Affected file server.c.
1123 * Fixed a bug in silc_server_new_server. The SilcServer was
1124 set as the new server's context instead of SilcServerEntry.
1125 This naturally caused some weird bugs.
1127 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1129 * Do not delete the channel rekey task when adding it
1130 for in silc_server_create_channel_key.
1132 * Changed the silc_server_create_channel_key to return
1133 TRUE or FALSE to indicate the success of the channel key
1136 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Fixed MSVC++ project files and added missing files to

1144 does not have it defined. Affected files are
1145 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1147 * Fixed buffer overflow from Irssi SILC Client. Affected
1148 file irssi/src/fe-common/core/themes.c.
1150 * Fixed double free in client library in the file
1151 lib/silcclient/client.c when disconnecting from server.
1153 * Applied double free patch from cras to Irssi SILC client.
1154 Affected files irssi/src/core/[modules/expandos].c
1156 * Fixed the disconnection handling to Irssi SILC Client.
1157 The application must call silc_client_close_connection
1158 in ops->connect client operation in case of failure of
1159 the connection. Affected file is
1160 irssi/src/silc/core/client_ops.c.
1162 * Do not set sock->protocol to NULL in the function
1163 silc_client_close_connection after executing the protocol's
1164 final callback since the sock might not be valid anymore.
1165 Affected file lib/silcclient/client.c.
1167 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Do not enable SILC_THREADS if the linking with libpthread
1170 did not happen. Affected file configure.in.pre.
1172 * Added notion to protocol specification that server must
1173 verify the sent authentication payload with CMODE when
1174 setting the channel founder key. Implemented it to the
1175 server. Affected file silcd/command.c.
1177 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Added _EXTRA_DIST SILC distribution variable to the
1180 distributions file. It is used to conditionally add extra
1181 files or directories to the specific distribution. Affected
1182 files ./prepare, Makefile.am.pre and distributions.
1184 Removed the `_' from the start of the distribution names.
1187 * Added README.WIN32 for instructions to compile the Toolkit
1190 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed a double free in disconnection in the server. Affected
1193 file is silcd/server.c.
1195 * Fixed the lib/silcske/groups.c to work now also with GMP
1196 MP library. The string conversion did not work when using
1197 specific base and the base is indicated in the string as well.
1199 * Created win32/ directory which now includes MSVC++ specific
1200 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1201 It will appear only in the toolkit distribution
1203 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Changed the key material distribution function in case when
1206 the hash output is too short. The data is now concatenated
1207 a bit differently than it used to. Made the change to the
1208 SKE protocol specification.
1210 * Added better GMP detection to configure.in.pre. A patch
1213 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Fixed a minor bug in SKE that might cause some problem on
1216 some platforms. Affected file lib/silcske/silcske.c.
1218 * Added the cookie checking for initiator in the SKE. It checks
1219 that the responder returns the sent cookie unmodified. The
1220 affected file is lib/silcske/silcske.c. Added new SKE
1221 error type INVALID_COOKIE that can be sent during the
1222 negotiation. Fixed some memory leaks as well.
1224 * Added the "invalid cookie" error message to Irssi SILC client's
1227 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Added `task_max' field to the SilcClientParams to indicate
1230 the maximum tasks the scheduler can handle. If set to zero,
1231 default values are used. Affected file lib/silcclient/silcapi.h.
1233 * Fixed memory leaks in silc_client_close_connection. Affected
1234 file lib/silcclient/client.c.
1236 * Added silc_client_del_client_entry to client library to free
1237 all memory of given client entry. Affected file is
1238 lib/silcclient/idlist.[ch].
1240 * Added new functions silc_client_del_channel and
1241 silc_client_del_server to delete channel and server entries.
1242 Affected file lib/silcclient/[silcapi.h/idlist.c].
1244 * Removed silc_client_del_client_by_id from silcapi.h.
1246 * Fixed the INFO command to return the server's own info
1247 correctly when querying by Server ID. Affected file is
1250 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Removed the non-blocking settings in WIN32 code in the
1253 silc_sock_[read/write] and added SleepEx instead. Affected
1254 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1255 of input data is now checked with FIONREAD and ioctlsocket.
1257 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Call silc_schedule_task_del_by_context in the
1260 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1261 Affected file lib/silccore/silcprotocol.c.
1263 * Call silc_protocol_cancel for active protocols in the
1264 silc_server_close_connection if the funtion
1265 silc_server_free_sock_user_data has not been called.
1266 Affected file silcd/server.c.
1268 * Generic tasks cannot be deleted using the del_by_fd
1269 task deleting function since generic tasks does not match
1270 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1272 * Added a notion to SILCOPER help file that the SILCOPER works
1273 only on router server, not on normal server.
1275 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Added for WIN32 support for the new scheduler as well.
1278 Affected file lib/silcutil/win32/silcwin32schedule.c.
1280 * Fixed the SHA1 implementation to work on various platforms.
1282 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1285 API. It is part of the scheduler now. Everything else is
1286 as previously but some functions has changed their names.
1287 Checkout the lib/silcutil/silcschedule.h for the interface.
1288 Updated all applications to use the new interface. Affected
1289 files are lib/silcutil/silcschedule.[ch].
1291 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Found a bug in the SKE implementation. The HASH value,
1294 specified by the protocol, was not computed correctly. The
1295 public key of the responder was not added to the computation
1296 even though it is mandatory. Affected file lib/silcske/silcske.c.
1297 This unfortunately causes incompatibilities with older
1298 clients and servers.
1300 * Added WIN32 specific network init and uninit functions:
1301 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1302 the Winsock2. Affected file lib/silcutil/silcnet.h and
1303 lib/silcutil/win32/silcwin32net.c.
1305 * Set the socket always to nonblocking mode on WIN32 after
1306 reading data or writing data. Affected file is
1307 lib/silcutil/win32/silcwin32sockconn.c.
1309 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Fixed various compilation problems under WIN32. Affected
1312 files lib/silcutil/win32/silcwin32thread.c and
1313 lib/silcutil/win32/silcwin32schedule.c.
1315 * Removed all _internal.h #includes from public header
1316 files. Internal headers must never be included from
1319 Removed also the lib/silcske/payload_internal.h file.
1321 * All include files that may be needed (public and some others
1322 included by the public headers) by application developers are
1323 now copied to the ./includes directory. It does not copy any
1324 internal headers. Affected file Makefile.defines.pre and all
1325 Makefile.am's under lib/ and subdirs.
1327 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1329 * Do not change the ~/.silc directory's permissions automatically.
1330 Affected file irssi/src/silc/core/clientutil.c.
1332 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Do not cancel the protocol in silc_server_close_connection
1335 it might cause recursion. Now cancelled in the function
1336 silc_server_free_sock_user_data. Affected file silcd/server.c.
1338 * Fixed the silc_server_remove_clients_by_server to regenerate
1339 the channel keys correctly finally. Added also new function
1340 silc_server_remove_clients_channels to actually do it.
1341 Affected file silcd/server.c.
1343 * Fixed the silc_server_new_channel to not crash by giving
1344 wrong router to the new channel. Affected file is
1345 silcd/packet_receive.c.
1347 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1350 which is given as argument to the silc_client_alloc now.
1351 It can be used to configure the client and set various parameters
1352 that affect the function of the client.
1354 * The USERS command in server did not check whether the channel
1355 is private or secret. Affected file silcd/command.c.
1357 * Added new argument to the USERS command in protocol specification.
1358 The USERS command now can take the channel name as argument
1359 as well. Added support for this in client and server and
1360 updated the protocol specs.
1362 * Completed the GETKEY command in client. It can be now used
1363 to fetch also servers public key not only some clients.
1364 Affected files lib/silcclient/command[_reply].c.
1366 * Added silc_client_get_server to return server entry by the
1367 server name. Affected files lib/silcclient/silcapi.h and
1370 * Redefined the IDENTIFY command in protocol specification to be
1371 more generic. It now can be used to query information about
1372 any entity in the SILC Network, including clients, servers and
1373 channels. The query may be based either the entity's name
1374 or the ID. Added support for this in both client and server.
1376 Affected files silcd/command.c and lib/silcclient/command.c
1377 and command_reply.c.
1379 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1380 the _from_client and _from_server functions. Affected file
1383 * Added silc_client_get_channel_by_id_resolve to the file
1384 lib/silcclient/silcapi.h to resolve channel information by
1385 its ID. Added also silc_client_get_channel_by_id that
1386 does not resolve it from the server.
1388 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Added SilcServerEntry context into the client library
1391 to represent one server. The INFO command now allocates
1392 these to save the resolved server info. For now on the
1393 client library will also keep information about servers,
1394 connected and resolved with INFO.
1396 The INFO command now allocates the SilcServerEntry context
1397 and saves the server info there. The COMMAND_REPLY in
1398 the INFO now returns the parameters to application in
1399 same order as defined in the protocol specification.
1401 The entries are cached in the client->server_cache.
1403 * The INFO command is now issued after received the Client ID
1404 from the server. Affected file lib/silcclient/client.c.
1406 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1407 to the application as the mode changer might be server.
1408 It is guaranteed that NULL is not returned anymore to the
1409 application. Affected file lib/silcclient/client_notify.c.
1411 The ID Type is now also passed to the application so that
1412 it can check whether the returned entry is SilcClientEntry
1415 Added new function silc_client_get_server_by_id to return
1416 the server entry by ID. Affected files are the
1417 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1419 * Do not create the channel in the Irssi SILC Client when issuing
1420 the JOIN command but when received the sucessful JOIN command
1421 reply. Otherwise the channel might get created even though we
1422 could not join it. The Affected file is
1423 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1425 * Fixed a channel joining bug in router. The router must also
1426 check the channel modes, invite and ban lists etc. when serving
1427 the JOIN command sent by normal server. Affected file is
1428 silcd/command.c. The router now resolves the client's
1429 information from the server who sent the JOIN command if it
1430 does not know it, and processes the JOIN command only after
1433 * Changed the SilcCommandCb to take new argument; void *context2.
1434 Affected file lib/silccore/silccommand.h
1436 The second argument in the command callbacks in the server now
1437 includes the SilcServerCommandReplyContext if the command was
1438 called as pending command callback from the command reply.
1439 Otherwise it is NULL. When called as pending the status of the
1440 command reply will be checked and if it was erronous the
1441 error will be sent to the original sender of the command.
1442 This way the client always receives the error messages even
1443 though the server was actually the one who received the error
1444 when it resent the command to router, for example. Affected
1445 files silcd/command[_reply].[ch].
1447 * Fixed sending WHOWAS command's error message to client if
1448 the requested client could not be found. It was missing.
1451 * Changed the CMODE and CUMODE commands reply arguments in the
1452 protocol specification. The Channel ID is now sent in both
1453 of the commands to identify the channel. Implemented this
1454 new feature to the client and server. Affected files
1455 lib/silcclient/command_reply.c and silcd/command.c.
1457 * Made better checks for invite and ban lists in the JOIN
1458 command in server. Affected file silcd/command.c.
1460 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * The server now performs the incoming host IP/DNS lookup
1463 using the silc_socket_host_lookup and thus does not block
1464 the server anymore. Affected file silcd/server.c.
1466 * Completed the multi-thread support for SILC Scheduler in
1467 the lib/silcutil/silcschedule.c.
1469 * Fixed the configure.in.pre to detect the pthread correctly
1472 * Fixed a deadlock in silc_task_queue_wakeup in the file
1473 lib/silcutil/silctask.c.
1475 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Added new function silc_schedule_wakeup that is used in
1478 multi-threaded environment to wakeup the main thread's
1479 schduler. It needs to be used when a thread adds a new task
1480 or removes a task from task queues. After waking up, the
1481 scheduler will detect the task queue changes. If threads
1482 support is not compiled in this function has no effect.
1483 Implemented the wakeup mechanism to both Unix and WIN32
1484 systems. Affected files are lib/silcutil/silcschedule.[ch],
1485 lib/silcutil/unix/silcunixschedule.c and the
1486 lib/silcutil/win32/silcwin32schedule.c.
1488 * Added new function silc_task_queue_wakeup to wakeup the
1489 scheduler by the specified task queue. Affected file
1490 lib/silcutil/silctask.[ch].
1492 * The silc_socket_host_lookup_start now wakes up the scheduler
1493 after adding the timeout task. Affected file is
1494 lib/silcutil/silcsockconn.c.
1496 * The silc_socket_host_lookup is synchronous now if the threads
1497 support is not compiled in. However, the callback is still
1498 called asyncronously through the scheduler, anyway. Affected
1499 file lib/silcutil/silcsockconn.c.
1501 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Added new function silc_socket_host_lookup to perform
1504 asynchronous IP and FQDN lookups for the socket connection.
1505 Affected files lib/silcutil/silcsockconn.[ch].
1507 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1510 that may or may not compile the mutex support in.
1512 Changed the silc_mutex_alloc interface. It allocates the
1513 mutex now to the sent pointer and returns TRUE or FALSE.
1515 Affected file lib/silcutil/silcmutex.h.
1517 * Wrote the SILC Task Queue interface to support multi-threads.
1518 Affected file lib/silcutil/silctask.[ch].
1520 * Wrote the SILC Scheduler to support multi-threads. Affected
1521 file lib/silcutil/silcschedule.c.
1523 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1526 in lib/silcutil/win32/.
1528 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Defined SILC Mutex API and SILC Thread API and implemented
1531 them for Unix. Affected files are
1532 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1533 lib/silcutil/unix/silcunixmutex.c and
1534 lib/silcutil/unix/silcunixthread.c.
1536 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Fixed the silc_server_remove_clients_by_server's channel
1539 key re-generation. The hash table handling was incorrect
1540 and would not work with many channels. Affected file is
1543 * Fixed some memory leaks around the server code.
1545 * Rewrote the silc_server_get_users_on_channel to support IPv6
1546 based Client ID's. Affected file silcd/server.c.
1548 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1549 specification. However, a separate document must be written
1550 to define the detailed signing procedure and the payload
1551 associated with the flag. Defined the flag to the
1552 lib/silccore/silcchannel.h as well.
1554 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Changed the dynamic tables to static size tables in the
1557 lib/silccrypt/silchmac.c.
1559 * Removed GCC dependencies from the code. A patch by cras.
1561 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Do not show the error "Error receiving packet bla bla"
1564 in server if it really was not an error (-2 means that reading
1565 is pending). Affected file silcd/server.c.
1567 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Fixed a possible crash in silc_server_remove_clients_by_server
1570 in silcd/server.c. Fixed there also some memory leaks.
1572 * Fixed the silc_idlist_replace_client_id. It could replace
1573 wrong key in the hash table. Affected file silcd/idlist.c.
1575 * Do not check whether there are global users on the channel
1576 if the channel->global_users is FALSE. Affected functions
1577 silc_server_remove_from_one_channel and
1578 silc_server_remove_from_channels in silcd/server.c. Also,
1579 do not check if the removed client is local as we can be
1580 sure that global client was not removed from the channel
1581 and checking for global users is not needed.
1583 * The silc_server_remove_clients_by_server now re-generates
1584 the channel keys correctly for those channels that had
1585 clients removed from them. Affected file silcd/server.c.
1587 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1589 * Found the reason of random crashes in the server. We weren't
1590 ignoring the SIGPIPE signal (which can be sent in write())
1591 and it crashed the server. Affected file silcd/silcd.c.
1593 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Assure that sock->user_data is not NULL in the function
1596 silc_server_packet_send in silcd/packet_send.c.
1598 * Disconnect the remote connection if it could not be added
1599 to any ID lists in the server. The affected file is
1602 * Check in silc_server_packet_send[_real/dest] that the
1603 socket is not disconnecting and ignore the data if it is.
1604 Affected file silcd/packet_send.c.
1606 * Define inline to __inline on native WIN32 compilation.
1607 Affected file includes/silcwin32.h.
1609 * Added some explicit type casts for inline code since MSVC
1610 require them. Affected files lib/silcutil/silcbuffer.h,
1611 lib/trq/silcdlist.h and lib/trq/silclist.h.
1613 * Print warning in log files from now on if the packet
1614 decryption fails. Affected file silcd/server.c.
1616 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Changed the `say' client operation's interface to accept
1619 new `type' argument to indicate the type of the message sent
1620 by the library. The application may filter the library's
1621 messages according the type. The affected file is the
1622 lib/silcclient/silcapi.h.
1624 * Added two new functions to lib/silcclient/silcapi.h:
1625 silc_client_del_client and silc_client_del_client_by_id.
1626 Affected file lib/silcclient/idlist.c.
1628 * Moved the clientincludes.h from includes/ to silc/ and
1629 serverincludes.h from includes/ to silcd/.
1631 * The modes for the CMODE and CUMODE are now passed as
1632 uint32 for application with COMMAND_REPLY. The affected
1633 file is lib/silcclient/command_reply.c.
1635 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * /WHOIS without arguments shows client's own information.
1638 Affected file lib/silcclient/command.c.
1640 * Changed PING to not accept any arguments. The specs
1641 says that client can ping only the connected server so
1642 requiring an argument is not needed. Affected file is
1643 lib/silcclient/command.c.
1645 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed a fatal bug in private message sending and reception
1648 encryption and decryption when using private message keys.
1649 The implementation was incorrect and did not follow the
1650 specification. It causd that some of the message were
1651 lost since it did not use the sending and receiving keys
1652 as the protocol suggests. This has been fixed and will cause
1653 incompatibilities with older clients when sending private
1654 message encrypted with private message keys. Affected files
1655 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1656 and various other in Irssi SILC Client.
1658 Added `responder' boolean argument to the functions
1659 silc_client_add_private_message_key[_ske] to indicate when
1660 the key is added as responder or initiator of the key
1663 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Removed the silc_ske_check_version function and created
1666 a SilcSKECheckVersion callback. Added also a function
1667 silc_ske_set_callbacks that is now used to set all SKE
1668 callbacks. The callback functions are not given to
1669 the SKE functions anymore, but this function is used to
1672 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1674 * Added `silc_version' argument to the silc_client_alloc
1675 to define the version of the application for the library.
1676 The library will use the version string to compare it
1677 against the remote host's (usually a server) version
1678 string. Affected file lib/silcclient/silcapi.h
1680 * Added the KE protocol context to Key Agreement context
1681 in client library so that we can abort the SKE if it
1682 is in process when we get timeout. Affected file is
1683 lib/silcclient/client_keyagr.c.
1685 * Do not resolve the client ID forever if it returns in the
1686 first time that such client does not exist. This was done
1687 for example with private message. Affected file is
1688 lib/silcclient/client_prvmsg.c.
1690 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Do not add regex.h for WIN32. The affected file
1693 includes/silcincludes.h.
1695 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1696 not work yet 100%. It generates the DLL's automatically
1697 when compiling with --with-win32 under cygwin.
1699 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * lib/contrib/regex.c is not compiled on WIN32.
1703 * Added silc_net_get_socket_opt function to the
1704 lib/silcutil/silcnet.h.
1706 * Added includes/silcwin32.h for WIN32 specific includes
1709 * Do not use ptime structure or any of the posix process
1710 functions on WIN32 in lib/silccrypt/silrng.c.
1712 * Added silc_gettimeofday to provide generic function
1713 for struct timeval on all platforms. Added the function
1714 to lib/silcutil/silcutil.h.
1716 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1719 library as they clearly belong there. As a plus side we
1720 can make the actual socket connection routines platform
1723 Added also new generic function silc_socket_read and
1724 silc_socket_write (that used to be silc_packet_[read/write].
1725 The implementation of these are platform specific.
1727 * Added WIN32 specific routines of silc_socket_[read/write]
1728 to lib/silcutil/win32/silcwin32sockconn.c.
1730 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Added preliminary support for native WIN32 compilation under
1733 cygwin (using the -mno-cygwin option for GCC) to the
1734 ./configure.in.pre. The --with-win32 now prepares the
1735 compilation for native WIN32.
1737 * Rewrote the SILC Scheduler interface in the file
1738 lib/silcutil/silcschedule.h. The scheduler is now context
1739 based and does not have anymore any global static scheduler.
1740 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1741 and created lib/silcutil/win32 directory for WIN32 based
1744 * Added Unix specific network routines to the
1745 lib/silcutil/unix/silcunixnet.c and the old
1746 lib/silcutil/silcnet.c includes now only generic routines.
1748 Added WIN32 specific network routines to the
1749 lib/silcutil/win32/silcwin32net.c.
1751 * Added Unix specific utility functions from the
1752 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1754 * Added WIN32 SILC Scheduler to the file
1755 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1758 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Do not handle JOIN notify in the server if the target client
1761 is not registered (idata->registered == FALSE). The affected
1762 file is silcd/packet_receive.c.
1764 * Update the nickrec->founder in event_cumode in the Irssi SILC
1765 client. Affected file irssi/src/silc/core/silc-channels.c.
1767 * Fixed the CUMODE_CHANGE notify handling in the server when
1768 server and router are announcing their clients on channels.
1769 Now the mode changes are saved and notified correctly. The
1770 affected file is /silcd/packet_receive.c.
1772 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1773 They really did not replace the cache entry in the ID Cache.
1774 Now they do that. Affected file silcd/idlist.c.
1776 * Fixed the KICK notify handling in the Irssi SILC client to
1777 update the channel records so that the kicked client does not
1778 appear to be on the channel. The affected file is
1779 irssi/src/silc/core/silc-channels.c.
1781 * Always update the conn->current_channel when executing command
1782 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1784 * Fixed the KILL notify handling in Irssi SILC client to remove
1785 the killed client on all channels.
1787 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1789 * Fixed the silc_parse_command_line to remove extra spaces
1790 from the start and end of the arguments. Affected file is
1791 lib/silcutil/silcutil.c.
1793 * Cancel and free any active protocol in the function
1794 silc_server_close_connection. Affected file silcd/server.c.
1796 * Cancel and free any active protocol in the function
1797 silc_client_close_connction. Affected file is
1798 lib/silcclient/client.c.
1800 * Do not execute the KILL command for clients that are in
1801 history (ie. they are not in the network). Affected file is
1804 * Fixed KILL notify handling, client does not crash anymore.
1805 Affected file irssi/src/silc/core/silc-channels.c.
1807 * Reduced the default packet buffer size from 2048 to 1024 in
1808 lib/silccore/silcpacket.c.
1810 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1811 counter to the SKE context that is incresed when the SKE library
1812 performs async operation outside the library. If the outside
1813 process frees the SKE context and FREED status will be set
1814 and the library will detect after the sync operation that the
1815 libary is freed. The affected files are
1816 lib/silcske/silcske[_status].[ch].
1818 * Resolve the client entry information in the function
1819 silc_client_channel_message to assure that NULL pointer is not
1820 passed as client entry to the application. */
1822 * Fixed the task timeout calculation to assure that there is
1823 never negative timeouts. The affected file is
1824 lib/silcutil/silcschedule.c.
1826 * Fixed the channel user mode notification sending in server.
1827 It was sent point-to-point to the router (or to server by router)
1828 but it needs to be destined to a channel. The routines now
1829 supports sending the channel user mode notifys to the channels
1830 when announcing clients and channels. Affected files are
1831 silcd/server.c and silcd/packet_receive.c.
1833 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1834 It did not actually replace the old channel entry in the cache.
1835 Affected file lib/silcclient/client_notify.c.
1837 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Fixed a possible crash in silc_packet_send_prepare. It now
1840 assures always that there is enough space in the buffer and
1841 at the tail area of the buffer (for MAC).
1843 Fixed the inbound buffer reallocation in silc_packet_read.
1844 It was old code and did not handle the reallocation correctly.
1847 The affected file is lib/silccore/silcpacket.c.
1849 * Fixed buffer overflow in silc_parse_nickname in the file
1850 lib/silcutil/silcutil.c.
1852 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * make install generates new server keys only if there is not
1857 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1860 Added check that if the NOREPLY is set then we will not send
1861 the away message. This avoids infinite loop of away messages
1862 if both clients are away. The affected file is
1863 lib/silcclient/client_prvmsg.c.
1865 * Fixed client crash if /NICK was given without arguments.
1866 Affected file lib/silcclient/command.c.
1868 * Server does not send the invite list in INVITE command back
1869 to the client if the list was not altered. Added this notion
1870 to the protocol spec as well. Affected file silcd/command.c.
1872 Fixed possible crash in INVITE command by checking the
1873 value of silc_server_get_client_route command.
1875 * Fixed the INVITE notify type handling. The arguments are now
1876 taken in correct order and client does not crash. The affected
1877 file is irssi/src/silc/core/silc-channels.c.
1879 Removed the "Inviting xxx to channel" message from the
1880 client library away and let the application handle it.
1881 Affected file lib/silcclient/command.c. Added that message
1882 to Irssi SILC client's message formats.
1884 * Fixed CMODE command crash in client. It now checks the
1885 amount of arguments correctly and does not crash. The affected
1886 file is lib/silcclient/command.c.
1888 * Do not create new channel automatically in silc_channels_join
1889 but check whether the channel by that name already exists.
1890 Affected file irssi/silc/core/silc-channels.c.
1892 * Do not send the SERVER_SIGNOFF to router if the disconnected
1893 entity was the router. Affected file silcd/server.c.
1895 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1896 SILC client as it was missing from there.
1898 Added the handling of the KICK notify to the Irssi SILC client
1899 as it was missing. Added "you have been kicked" message to
1900 Irssi SILC client's message modules formats.
1902 Added the handing of the KILL notify to the Irssi SILC client
1903 as it was missing. Added the kill message module formats
1906 The affected file is irssi/src/silc/core/silc-channels.c.
1908 * The router did not save the channel mode the server announced.
1909 Affected file silcd/packet_receive.c.
1911 * Fixed a possible crash in INFO command in server. If the
1912 server did not provide the server info it crashed. Affected
1913 file silcd/command.c.
1915 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * Fixed the GETKEY command in the server to check also the
1918 global list. Otherwise the GETKEY would not work correctly
1919 in normal SILC server. Affected file silcd/command.c.
1921 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1923 * Fixed GETKEY crash, it crashed if the command did not succseed.
1925 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1928 is now real and not just an macro interface to GMP.
1930 Removed the entire GMP from the source tree and imported new
1931 NSS MPI library instead. Reason for removing GMP is that it is
1932 extremely large and compiles extremely slow. The NSS MPI
1933 is only a few files and compiles in less than 10 seconds.
1934 The speed is also about the same as GMP. The MPI is imported
1935 to lib/silcmath/mpi.
1937 If the system has GMP installed we will still use the GMP.
1938 If it is not then the NSS MPI will be compiled.
1940 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Merged a long nickname (127 characters long) crash bugfix from
1943 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1945 * Merged a freed memory reference bugfix from Irssi CVS tree.
1946 Affected file irssi/src/core/commands.c.
1948 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Added the server's public key sving and verification to the
1951 server when performing the SKE. This was missing and the
1952 remote server's (or router's) public key was accepted without
1953 checking whether we have it previously or trust it at all.
1954 Affected file silcd/protocol.c.
1956 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Check in the silc_server_timeout_remote if protocol is active
1959 and make sure that the protocol's final callback is called so
1960 that all memory if freed. Affected file silcd/server.c.
1962 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1964 * silc_server_whois_send_reply crashed the server if the nickname
1965 was 127 characters long. Affected file silcd/command.c.
1967 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1969 * Added sanity check to the silc_server_new_client. If the hostname
1970 is provided inside username then check that the provided hostname
1971 really is the same as the resolved one. If the hostname was not
1972 resolved then check it from the public key. Affected file is
1973 silcd/packet_receive.c.
1975 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1976 if the server disconnected us and the connection is not valid
1977 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1979 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1980 the library to the lib/silcutil/silcutil.[ch].
1982 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Close log file after open. Affected file
1985 lib/silcutil/silclog.c.
1987 * Check whether sock == NULL in silc_client_send_packet and return
1988 if it is. Affected file lib/silcclient/silcclient.c.
1990 * Check rec->entry == NULL in the Irssi SILC Client before
1991 sending the channel message. Affecte file is
1992 irssi/src/silc/core/silc-servers.c.
1994 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Merged a splitted window bugfix from Irssi CVS tree. The
1997 affected file is irssi/src/fe-text/textbuffer-view.c.
1999 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2000 It did not print nickname.
2002 * Improved the distributions system a bit.
2004 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2007 irssi/src/fe-text/gui-window.c.
2009 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2010 to in-active server. The affected file is
2011 irssi/src/silc/core/client_ops.c.
2013 * Resolve the client in USERS command reply if the entry does
2014 not have username resolved. The affected file is
2015 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2016 command to WHOIS command to really resolve stuff. The USERS
2017 is not used any more in any critical section so WHOIS can
2018 be used even though it might be slower than IDENTIFY.
2020 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2023 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Changed the protocol API a bit more consistent in the
2026 lib/silccore/silcprotocol.[ch].
2028 * Changed the following headers to ROBODoc format:
2030 lib/silccore/silcpayload.h
2031 lib/silccore/silcprotocol.h
2032 lib/silccore/silcsockconn.h
2034 All core library headers are now formatted.
2036 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Fixed a bug in Irssi SILC client; do not show that you are
2039 server/router operator if you really are not. Affected file is
2040 irssi/src/silc/core/client_ops.c.
2042 * Renamed silc_command_free_payload to silc_command_payload_free.
2043 Affected file lib/silccore/silccommand.h
2045 * Added silcmath.h to include the prototoypes of various routines
2046 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2049 * Changed the following headers to ROBODoc format:
2051 lib/silccore/silcchannel.h
2052 lib/silccore/silccommand.h
2053 lib/silccore/silcid.h
2054 lib/silccore/silcidcache.h
2055 lib/silccore/silcmode.h
2056 lib/silccore/silcnotify.h
2057 lib/silccore/silcpacket.h
2058 lib/silcmath/silcmath.h
2060 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2062 * Added checking to the server code not to start the server if
2063 ciphers and stuff are not configured properly. Affected files
2064 silcd/serverconfig.[h] and silcd/server.c.
2066 * Changed the layout of the header files of the public interfaces
2067 in the SILC libraries. The new layout supports ROBODoc
2068 documentation tool (and some others) so that it is easy to create
2069 a library reference manual. All the other headers and source
2070 code must still follow the CodingStyle document. Also source
2071 code must not include these ROBODoc stuffs, only the headers.
2072 Furthermore, all public interface headers must now be named
2073 by using `silc' prefix, example: silcapi.h, silccipher.h.
2074 Some files were renamed due to this. All the other headers
2075 must not be used as public interfaces. I will update the
2076 CodingStyle document later. Changed following headers, so far:
2078 lib/silcclient/silcapi.h
2079 lib/silccore/silcauth.h
2080 lib/silccore/silcprivate.h
2081 lib/silccrypt/silcdh.h
2083 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * Removed silc_client_packet_send_flush from the client library
2088 as it is not needed. Affected file lib/silcclient/client.[ch].
2090 * Added printing of message of unresolved authentication method
2091 to the Irssi SILC client. Added it to the module formats.
2092 Removed the same message from the client library.
2094 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Added new distribution feature, DISTLABEL. Every distribution
2097 can define own preprocessor label that can be used in the
2098 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2099 file distributions, acconfig.h.pre and prepare.
2101 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Added Makefile.defines_int to include the actual definitions
2104 for Makefile.defines.in. Tested the new distribution system,
2105 created distributions and tested installation.
2107 * Added AWAY message printing to the Irssi SILC client. Added
2108 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2110 * Added SCONNECT command to call the SILC's CONNECT command.
2111 Cannot use CONNECT directly since Irssi uses that internally.
2112 Affected file irssi/src/silc/core/silc-servers.c.
2114 Added ACTION local command. It is same as ME command but takes
2115 the channel as mandatory argument.
2117 Rewrote some of the Irssi's help files to suite for SILC
2120 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Added Makefile.defines[.in] that should for now on be included
2123 in all Makefile.am file in the source tree. That file includes
2124 all common compilation definitions for SILC source tree.
2126 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * Minor changes to the ./prepare script to change the package
2129 name according the distribution name to the configure.in.
2131 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Created new distribution system. Added file `distributions'
2134 that defines all the distributions that can be created out of
2135 the SILC source tree. The ./prepare script now reads that
2136 file to determine how to prepare the distributions. The
2137 first argument to the ./prepare is the name of the distribution
2138 and second is the version of the distribution. If given
2139 without arguments it creates the default (toolkit) distribution
2140 with the default version (defined in ./prepare).
2142 All Makefile.am files that are subject to the distributions
2143 are now named as Makefile.am.pre. These are ./Makefile.am
2144 and lib/Makefile.am. Others may be changed later.
2146 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Added invite list, ban list, some key management and connection
2149 error message printing to module formats in the Irssi SILC client.
2151 * Added new silc_client_set_away_message to set the away message
2152 that is back to the person who sent private message. The
2153 affected file lib/silcclient/silcapi.h and the
2154 lib/silcclient/client_prvmsg.c.
2156 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Fixed the private message sending in the Irssi SILC client,
2159 added local command KEY to the Irssi SILC client.
2161 Added key management and key agreement message formats to the
2162 irssi/src/fe-common/silc/module-formats.[ch].
2164 Added USERS (alias WHO) printing, server/router operator
2165 indication and LIST command printing to the module formats.
2167 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Fixed channel joining notify handling, cumode notify handling
2170 from Irssi SILC client.
2172 * Added SILC specific module-formats to the Irssi SILC client so
2173 that SILC specific message hilighting, colors etc is possible.
2174 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2176 Added channel mode, channel user mode, actions, notices,
2177 whois and whowas printing to the the module-formats.c.
2179 * Fixed a bug in channel deletion in the server. The channel
2180 is not left to the cache even if the channel founder auth mode
2181 is set when there are no users anymore on the channel. Affected
2182 file silcd/server.c.
2184 * The silc_net_localhost now resolves the entire hostname including
2185 the domain name. Affected file lib/silcutil/silcnet.c.
2187 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Changed the ask_passphrase client operation to be ascynchronous.
2190 It has now a completion callback and a context that the
2191 application must call after it has got the passphrase from
2192 the user. Affected files lib/silcclient/silcapi.h,
2193 lib/silcclient/protocol.c, lib/silcclient/command.c and
2196 Added SilcAskPassphrase callback that the application calls
2197 to deliver the passphrase to the library.
2199 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2200 The public key verification and especially a certificate
2201 verification is asynchronous procedure.
2203 Added new SILC_SKE_STATUS_PENDING status to indicate the
2204 request is pending and a callback will be called to finalize
2207 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2208 indicate that remote end did not send its public key (or
2209 certificate), even though we require it. Added check for this
2210 condition in the SKE. This was a security bug, now fixed.
2212 Defined new SilcSKEVerifyCbCompletion callback that is called
2213 when the verification process is completed.
2215 The affected files lib/silcske/silcske_status.h and
2216 lib/silcske/silcske.[ch].
2218 * Changed the verify_public_key client operation to be async
2219 as well. Defined SilcVerifyPublicKey callback that is used to
2220 indicate the success of the public key verification process.
2222 Changed the server and client to use the new async client
2225 * Changed the Irssi SILC client's internal scheduler to be called
2226 twice as many times as it used to be. As a result the client
2227 should be a bit faster now. Affected file is
2228 irssi/src/silc/core/silc-core.c.
2230 * Added support to Irssi SILC client of asynchronous public key
2231 verification and passphrase inquiry. Affected file is
2232 irssi/src/silc/core/silc-core.c.
2234 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Do not say "You have left channel %s" in client library.
2237 Moved it to the application. Affected files are
2238 lib/silcclient/command.c and silc/client_ops.c.
2240 * Fixed silc_client_get_clients. Command context was not
2241 duplicated and was freed memory in the callback. Affected
2242 file lib/silcclient/idlist.c.
2244 * Do not say "you are now talking..." on JOIN command in the
2245 client library. The appliation must handle it.
2247 * Do not say ".. changed topic to" in command reply in the
2248 client libary. The application must handle it.
2250 * Fixed TOPIC command sending in the client library.
2252 * Fixed a memory leak in silc_client_command_free in the file
2253 lib/silcclient/command.c.
2255 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Imported a modified version of Irssi client to the source tree.
2258 The Irssi will be used to create a new client called
2259 Irssi SILC. Imported to irssi/.
2261 Added silc_core_init_finish function to the Irssi. Affected
2262 file irssi/configure.in.
2264 A lot changes in the Makefile.ams around the irssi tree.
2266 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Do not rehash if the new size is same as the old size of the
2269 hash table, in the silc_hash_table_rehash*. The affected file
2270 lib/silcutil/silchashtable.c.
2272 * Replaced hash_table_del_by_context calls from the server
2273 (when channel->user_list and client->channels) to the
2274 hash_table_del as it is sufficient and faster.
2276 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Added silc_hash_table_list, silc_hash_table_get and the
2279 SilcHashTableList structure to provide an alternative way to
2280 traverse the hash table. The affected files are
2281 lib/silcutil/silchashtable.[ch].
2283 * Changed the server's idlist routines to use the hash table
2284 routines to optimize the code.
2286 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Replaced the client entry's `channel' list and channel entry's
2289 `user_list' list to hash tables for optimized lookup. Changed
2290 the code to use the hash table interface around the code.
2291 Affected file lib/silcd/idlist.[ch].
2293 * Added `auto_rehash' boolean argument to the function
2294 silc_hash_table_alloc to indicate whether the hash table should
2295 auto-rehash when it thinks is appropriate time. It will
2296 increase the hash table size if the there is twice as much
2297 entries in the table than the size of the table, and will
2298 decrease the size if there are twice as less entries than
2299 the size of the table.
2301 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2305 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * silc_idcache_purge_by_context deletes the entry now by context
2308 as it is supposed to do. Affected file lib/silccore/idcache.c.
2310 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2311 client is not anymore valid (WHOWAS givens the info) and not
2312 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2314 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Removed the `data' and `data_len' arguments from the ID Cache
2317 interfaces and added `name' argument. ID Cache does not handle
2318 anymore the binary data only a names associated with given ID.
2320 * When hashing a Client ID with silc_hash_id the entire ID is
2321 not hashed anymore, instead only the hash of the Client ID is
2322 hashed. This way we can access the Client ID from the cache
2323 with Client ID but with the hash of the ID (which is a hash of
2324 the nickname) as well without any difference in performance.
2326 Added also silc_idcache_find_by_id_one_ext to do one on one
2327 searching when we have the actual ID. Added also function
2328 silc_hash_client_id_compare. The affected files are
2329 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2331 * When hashing the name associated with a ID it is always done
2332 in lowercase. This way we can access the cache without worrying
2333 about case-sensitivity, even though, for example nicknames are
2336 * Fixed a bug in server with channel message sending. It put
2337 wrong ID type as destination ID. The affected file
2338 silcd/packet_send.c.
2340 * silc_idcache_del_by_context now deletes from all hash tables
2341 by context. Affected file lib/silccore/idcache.c.
2343 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Changed the client library to use the new ID Cache interface.
2346 Changes around the source tree.
2348 * Added silc_hash_table_rehash_ext to rehash with specific
2349 hash function. Affected file lib/silcutil/silchashtable.[ch].
2351 * Added silc_hash_string_compare to compare two strings in the
2352 hash table. Affected file lib/silcutil/silcutil.[ch].
2354 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Added new function silc_idcache_del_by_context into the
2357 lib/silccore/idcache.[ch].
2359 * Changed the server's ID list routines to use the new ID Cache
2360 interface. Changes around the source tree.
2362 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Added silc_hash_table_del[_by_context]_ext functions in to the
2365 lib/silcutil/silchashtable.[ch].
2367 Removed silc_hash_table_find_all* routines and added new
2368 silc_hash_table_find_foreach to replace them.
2370 Added silc_hash_table_replace_ext function as extended
2371 replacing function. Separated the simple hash table interface
2372 from the extended hash table interface in the file
2373 lib/silcutil/silchashtable.h.
2375 * Fixed minor bugs and changed it to use some of the new
2376 hash table functions in lib/silccore/idcache.c
2378 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2380 * Added new function silc_hash_table_find_all to return all keys
2381 in the hash table by the specified key. As the hash table is
2382 collision resistant it also makes it possible to have several
2383 duplicate keys in the hash table. This function may be used to
2384 find all of the keys from the hash.
2386 Added user_context arguments to the SilcHashFunction,
2387 SilcHashCompare and SilcHashDestructor to deliver user specified
2390 Added new fuctions silc_hash_table_find[_all]_ext to do
2391 extended lookup with specified hash and compare functions and
2392 specified user contexts.
2394 Added new function silc_hash_table_add_ext to add the key
2395 with specified hash function and user context.
2397 Added new function silc_hash_table_foreach to traverse all
2398 entrys in the hash table. Added SilcHashForeach callback
2401 Added new function silc_hash_table_del_by_context to delete
2402 the entry only if the context associated with the key matches.
2404 Affected files are lib/silcutil/silchashtable.[ch].
2406 * Removed silc_hash_[server/client/channel]_id and added just
2407 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2408 silc_hash_id_compare to compare two ID's using as the hash table
2409 comparison function. Added also silc_hash_data to hash
2410 binary data and silc_hash_data_compare to compare it.
2412 * Removed silc_idlist_find_client_by_hash as it is not needed
2413 anymore. Affected file silcd/idlist.[ch].
2415 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2416 to use internally the SilcHashTable. The new ID Cache is a lot
2417 faster than the old one. Some of the ID Cache interface was also
2418 rewritten and obsolete and stupid functions were removed.
2420 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Added entry_count field to the SilcHashTable to keep the number
2423 of the entries in the table. Implemented the function
2424 silc_hash_table_rehash. Added new function
2425 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2427 Fixed a minor bug in silc_hash_table_free.
2429 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2430 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2431 into the lib/silcutil/silcutil.[ch].
2433 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Implemented a collision resistant hash table into the
2436 lib/silcutil/silchashtable[ch]. See the header and the source
2437 for the SilcHashTable API.
2439 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Merged dotconf version 1.0.2 into lib/dotconf.
2443 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Do not compile anything in lib/silcsim/* if the SIM support
2446 is not enabled. The tree should now compile without problems
2449 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Compiled the SILC under cygwin. Compiled and tested briefly
2452 without problems. More tests needed. The SIMs didn't compile
2455 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2457 * Fixed possible crash in silc_get_username in the
2458 lib/silcutil/silcutil.c.
2460 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Fixed a va_arg in silc/client_ops.c.
2464 * Oops, RC5 routines were named AES and caused some problems
2465 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2467 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Added new SilcIDIP structure into the lib/silccore/id.h and
2470 replaced the old `ip' fields from all SILC ID's to that type.
2471 This is a step towards IPv6 support.
2473 The silc_id_get_len takes now the ID as an extra argument.
2474 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2475 both IPv4 and IPv6 based ID's.
2477 The affected files are lib/silccore/id.[ch] and other files
2478 around the tree using these routines.
2480 * Removed the ID length arguments in server from various
2481 silc_server_send_notify_* routines -> they are not needed
2484 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Fixed memory leak in silc_encode_pem_file in the file
2487 lib/silcutil/silcutil.c.
2489 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Check minor version as well in the SKE. Affected files are
2492 silcd/protocol.c and lib/silcclient/protocol.c.
2494 * Added --identifier option to the server so that an identifier
2495 can be when creating the public key for the server. Affected
2496 file is silcd/silcd.c.
2498 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2499 lib/silccrypt/silcpkcs.c.
2501 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Register default ciphers and stuff when using -C option with
2504 the server. Affected file sildc/silcd.c.
2506 * Put back the servers public key filename format, it is better
2507 than the new one. For now, the client keys are saved with the
2508 new filename format. The affected file silc/client_ops.c.
2510 * Implemented the Cipher API for the rest of the ciphers that
2511 did not implement it or implemented it the wrong way.
2513 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Register default ciphers and stuff when using the -S option
2516 in the client. Affected file silc/silc.c. Same also when
2517 creating new key pair with -C option.
2519 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Fixed the silc_verify_public_key client operation function to
2522 save the public keys differently. The fingerprint is now
2523 used as filename and not the hostname. This way also the
2524 client keys are saved uniquely and not with hostnames. The
2525 affected file is silc/client_ops.c.
2527 * Trimmed the silc_hash_fingerprint function to remove extra
2528 whitespaces from the end of the fingerprint. The affected
2529 file is lib/silccrypt/silchash.c.
2533 * Added silc_cipher_register_default function to register all
2534 default ciphers. It can be used when configuration files
2535 does not exist and the application does not want any specific
2536 ciphers in any specific order.
2538 The SilcDList is now used as silc_cipher_list dynamically
2539 allocated cipher list. Removed the static list all together
2540 and now all ciphers must be allocated to the dynamic list.
2541 The silc_cipher_alloc routine was changed to check only the
2544 All silc_cipher_* routines that used to return int returns
2547 The affected files lib/silccrypt/silccrypt.[ch].
2549 * The same thing was done to silc_hash_* as for silc_cipher_*
2550 routines. Affected files lib/silccrypt/silchash.[ch].
2552 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2553 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2554 Added also silc_pkcs_[un]register[_default] functions.
2555 Removed the data_context from the PKCS API.
2557 * Added silc_hmac_register_default function to register default
2558 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2559 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2560 to unregister all hmacs at once.
2562 * Register the default ciphers, hash functions, PKCSs and HMACs
2563 if client's configuration file does not exist. The affected
2566 * The client did not load the hash functions from the SIM
2567 modules at all. Added support for this. Affected file is
2568 silc/clientconfig.c.
2570 * When decoding public key with silc_pkcs_public_key_decode, check
2571 the supported algorithm only if PKCS are registered. Affected
2572 file lib/silccrypt/silcpkcs.c. The same was done with the
2573 silc_pkcs_private_key_decode.
2575 * Fixed the SILC List routines to keep the list always in order.
2576 It used to change the list's order when traversing the list but
2577 not it preserves the order. Affected file lib/trq/silclist.h.
2579 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Added the client library to use the SilcSocketConnection's
2582 reference counter (by silc_socket_dup) to prevent the bug that
2583 the socket object may be freed underneath async operation.
2585 * The name resolv library checking fixes in the configure.in.pre.
2588 * Created new version of the protocol drafts for future
2589 development. The -03 drafts are the ones that will be changed
2590 in the trunk now and the -02 will remain as they are.
2592 * Send list of CUMODE notifys to the router when announcing
2593 the channel users to the router. Affected file silcd/server.c.
2594 If the router receiving channel founder CUMODE for a channel
2595 that already has channel founder it will send CUMODE notify
2596 to the sender to remove the channel founder rights from the
2597 announced client. Affected file silcd/packet_receive.c.
2599 * The CUMODE notify may now use Server ID as well as the entity
2600 who changes the mode. Updated protocool specs.
2602 * Updated INSTALL and README files.
2604 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * New web pages in the http://silc.pspt.fi. The pages was
2611 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Implemented the [DenyConnectin] config section in the server.
2614 Added silc_server_config_denied_conn to check whether incoming
2615 connection is denied. Affected file silcd/serverconfig.[ch].
2617 * Do not check the ports when checking the incoming configuration
2618 data if the port is 0, meaning any. Affected file is
2619 silcd/serverconfig.c.
2621 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Fixed buffer overflow in silc_string_compare in the file
2624 lib/silcutil/silcutil.c.
2626 * Fixed double free in silc_server_command_leave in the file
2629 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Fixed the version checking in the server. Affected file is
2634 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Fixed the configuration data fetching when accepting new
2637 connections in the server. Affected file silcd/server.c.
2639 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Added `sender_entry' argument to the function
2642 silc_server_packet_relay_to_channel so that we can check
2643 whether some destination actually belongs to the same route
2644 the sender belongs (ie, we must not resend the packet to the
2645 sender). Affected file silcd/packet_send.[ch].
2647 * Added `servername' field to the SilcClientEntry in the server
2648 to hold the name of the server where client is from. Affected
2649 file is silcd/idlist.h.
2651 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Moved the channel message encrypting in the router betwen
2654 router connections from silc_server_channel_message to the
2655 silc_server_packet_relay_to_channel since we want to check
2656 whether we have anybody channel before encrypting anything.
2657 Affected files silcd/packet_[receive/send].c.
2659 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Fixed the [AdminConnection] server config section to support
2662 multiple entries. Affected file silcd/serverconfig.c.
2664 * Added support into the server to check the validity of the
2665 incoming connection before executing any KE or authentication
2668 * The connection configuration is now saved to the KE and
2669 connection auth protocol contexts and not fetched anymore in
2670 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2672 * The local hosts listenning address and port is also resolved
2673 now when starting the server. We want to have the socket object
2674 to include the real address and port for the listener. Added
2675 new function silc_net_check_local_by_sock into the files
2676 lib/silcutil/silcnet.[ch].
2678 * Fixed a broadcast bug in server -> do not broadcast if we
2681 * Fixed a routing bug. Do not route broadcast packets ever.
2682 Broadcast packets must be processed always and not routed since
2683 they may be destined to some other host than yourself and thus
2684 would get routed without no good reason. Affected file is
2687 * Added function silc_server_config_is_primary_route to check
2688 whether primary router connection has been configured (a router
2689 configuration that we are initiating). If there is not, we
2690 will assume that there is only two routers in the SILC network
2691 and we will use the incoming router connection as our primary
2692 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2694 * Changed the order of the broadcasting. Broadcast _after_ the
2695 packet has been processed not before. Affected file is
2698 * Fixed a [ClientConnection] parsing bug. The port was never
2699 parsed correctly thus resulting to port 0. Affected file
2700 silcd/serverconfig.c.
2702 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2703 argument and did not set the broadcast packet flag. Affected
2704 file silcd/packet_send.c. Fixed same bug in the function
2705 silc_server_send_notify as well.
2707 * If we receive NEW_ID packet for our own ID in the server, ignore
2710 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Removed the nickname from the Private Message Payload.
2715 Updated the code and the protocol specs.
2717 * Updated protocol specs for submitting to the IETF.
2719 * Tweaked the Random Number Generator a bit. Affected file
2720 lib/silccrypt/silcrng.c. Exported a new function
2721 silc_rng_[global]_add_noise which can be used to add more
2724 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Do not parse packets with different timeout when protocol
2727 is active -> may cause problem with rekey. Affected file
2730 * When server receives signoff notify it must not create
2731 new channel key if the client is on any channels since the
2732 sender of the signoff notify will create it.
2734 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Added printing of error messages during SKE protocol from the
2737 failure packet sent by server during SKE. Affected file
2740 * Removed the client's failure_callback handling with timeout
2741 and handle it immediately when received.
2743 * The SKE library returned wrong type in SUCCESS and FAILURE
2744 packets. They must be 32 bit MSB not 16 bit MSB.
2746 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Ok, rewrote the logic of the re-key and now it seems to work.
2749 I tested it on high traffic with frequent re-keys without
2750 problems. Added hmac_receive (and renamed hmac to hmac_send)
2751 in SilcClientConnection in lib/silcclient/client.h and
2752 in SilcIDListData in silcd/idlist.h. Also, removed the
2753 SilcPacketParserContext's cipher and hmac fields as they are
2754 not needed anymore and actually caused some problems when
2755 the ciphers and hmac's changed underneath the packet parser.
2757 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * If re-key protocol is active then process the incoming packets
2760 synchronously since we must assure that icoming packets encrypted
2761 with the old key is processed before the new keys is set to
2762 use. This is true other packets than for REKEY packets.
2763 Affected file silcd/server.c. The same was done to client library
2764 as well, affected file lib/silcclient/client.c.
2766 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Fixed bug in client and server to accept the force send if
2769 the packet is send from silc_[server/client]_packet_process
2770 function. Otherwise the packets are never delivered, oops.
2772 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Disable force sending of packets when REKEY protocol is active.
2775 We must assure that no packet is sent directly when rekey is
2776 performed. All packets must be sent through packet queue.
2777 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2778 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2779 function is silc_[server/client]_packet_send_real to check
2782 * Replaced the SIM paths from example config files to
2783 /usr/local/modules. Also, make install creates now
2784 /usr/local/silc/logs directory to hold all the SILC server
2787 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Made the configure.in.pre work on Solaris. Patch by salo.
2791 * Made all ciphers compatible with non-x86 machines. Defined
2792 CBC mode macros into lib/silccrypt/ciphers_def.h.
2794 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Fixed the make install.
2798 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * When MAC computation fails the silc_packet_decrypt returned 0
2801 even though it was supposed to return -1. Fixed this. The
2802 affected file is lib/silccore/silcpacket.c.
2804 * Do not replace the config files in /etc/silc (in make install)
2805 if they already exist. Affected file ./Makefile.am.
2807 * Do not send re-key packets immediately but through packet queue.
2808 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2810 * Changed silc_net_check_host_by_sock to return FALSE if the
2811 IP/DNS could not be resolved. Though, it returns the IP address
2812 now even if it could not resolve it (but returns also FALSE).
2813 Affected file lib/silcutil/silcnet.[ch].
2815 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Added silc_pkcs_decode_identifier to decode the public key's
2818 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2819 Added also silc_pkcs_free_identifier. Added also new context
2820 SilcPublicKeyIdentifier.
2822 * Added -S option to the silc client. It is used to dump the
2823 contents of the specified public key file.
2825 * Changed the PKCS api to return the public key length when
2826 setting the public key.
2828 * Fixed a fatal bug in the public and private key file loading.
2829 Affected file lib/silccrypt/silcpkcs.c.
2831 * Execute the packet parsing for client with zero (0) timeout
2832 if the protocol is active. Affected file silcd/server.c.
2834 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Made the key generation options to the silcd program. Added
2837 -C option, equivalent to client's option.
2839 * Added new [ServerKeys] config section to the server. It
2840 configures the server's public and private key.
2842 * Defined generic Public Key Payload into the protocol
2843 specification to send specific type of public keys and
2846 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2847 public key or certificate.
2849 * Implemented the GETKEY command to the server and to the
2850 client library and on user interface.
2852 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Made preliminary `make install' work.
2856 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Added SilcServerRekey context into silcd/idlist.h.
2860 * Added the PFS support as defined in the specification to the
2861 SKE protocol. Affected files lib/silcske/*.c.
2863 * Added `ske_group' field to the SilcServerRekey context to hold
2864 the number of the SKE group that is used with PFS in re-key.
2865 Affected file silcd/idlist.h.
2867 * Added PFS re-key support to the server. Affected file is
2870 * Added silc_protocol_cancel to cancel execution of the next
2871 state of the protocol. Affected file is
2872 lib/silccore/silcprotocol.[ch].
2874 * Added the re-key support with and without PFS to the client
2875 library. Re-key is performed once in an hour, by default.
2877 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2878 Added silc_client_rekey_callback and silc_client_rekey_final.
2879 Affected files are lib/silcclient/protocol.[ch] and
2880 lib/silcclient/client.[ch].
2882 * Removed the `hmac_key' and `hmac_key_len' fields from the
2883 SilcClientConnection structure; not needed. Affected file is
2884 lib/silcclient/client.h.
2888 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Do not ask whether user wants to use the negotiated private key
2891 for private messages, just use it. Affected file is
2892 silc/local_command.c.
2894 * Added `send_enc_key' and `enc_key_len' fields to the
2895 SilcIDListData structure since they are needed in the re-key
2896 phase. Affected file is silcd/idlist.[ch].
2898 * Implemented the simple re-key protocol into the server.
2899 Affected files silcd/server.c and silcd/protocol.[ch]. The
2900 re-key will be performed once in an hour, by default.
2902 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2903 Added silc_server_rekey, silc_server_rekey_callback and
2904 silc_server_rekey_final.
2906 * Removed Tunneled flag from the protocol. Updated the code
2907 and the specifications.
2909 * Adde `pfs' field to the SilcIDListData to indicate whether
2910 the PFS is to be performed in the re-key. Affected file is
2913 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2916 int64 of at least the xintXX size. If void * is less that 4
2917 bytes uint32 * will be used. Defined bool as boolean.
2919 * Changed _ALL_ unsigned long and unsigned int to uint32,
2920 unsgined short to uint16 in the source tree.
2922 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2923 not handle clients that has entry->data.registered == FALSE.
2924 They are not in the network anymore. Affected file is
2927 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Implemented the sending of the SERVER_SIGNOFF notify in the
2930 server. Affected file is silcd/server.c.
2932 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2933 Added also silc_notify_payload_encode_args into the
2934 lib/silccore/silcnotify.[ch].
2936 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2937 Affected file silcd/packet_receive.c.
2939 * Implemented the SERVER_SIGNOFF notify handling in the client
2940 library. Affected file lib/silcclient/client_notify.c. Also,
2941 implemnted the printing of the SERVER_SIGNOFF info to the
2942 application. Affected file silc/client_ops.c.
2944 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2945 if the deleting was successful. Affected file silcd/idlist.[ch].
2947 * Added support for public key authentication in the connection
2948 authentication protocol in the client library. Affected file
2949 lib/silcclient/protocol.c.
2951 * Changed the server's silc_idlist_get_clients_by_* interface
2952 to support already allocated array so that new entries may be
2953 added to pre-allocated array. Affected file silcd/idlist.[ch].
2954 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2955 and command replies.
2957 * All command reply functions in the server now calls the
2958 pending command callback even if error occured. This way the
2959 error will be delivered to the client as well. Affected files
2960 silcd/command.c and silcd/command_reply.c.
2962 * Fixed INFO command to return local server's info if no server
2963 was provided. Affected file lib/silcclient/command.c.
2965 * Removed RESTART command for good. Updated the code and the
2968 * Rewrote parts of the task system. It is a bit simpler now.
2969 Removed unsued task priorities. The affected files are
2970 lib/silcutil/silctask.[ch].
2972 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Moved the USERS printing from the library to the application.
2975 Affected files lib/silcclient/command.c and silc/client_ops.c.
2977 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added channel key re-key support. The re-key is perfomed
2982 only by the router and is done once in an hour. Added `rekey'
2983 field to the SilcChannelEntry in the server. Affected files
2984 silcd/server.c and silcd/idlist.h.
2986 * Added silc_task_unregister_by_context into the file
2987 lib/silcutil/silctask.[ch].
2989 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Added SILC_UMODE_GONE mode to indicate when the client is not
2992 present in the SILC network. Added also support to the local
2993 command AWAY that will set this mode. Added support of showing
2994 "xxx is gone" in WHOIS command. The USERS command shows the
2995 gone status as well.
2997 * Fixed setting server and router operator privileges in the
2998 server's UMODE command. Affected file silcd/command.c.
3000 * Merged the SKE KE1 and KE2 payloads into one payload. The
3001 new KE payload is equivalent to the old KE2 payload.
3003 Cleaned up the SKE Start Payload parsing. It now uses the
3004 simple buffer unformatting to do the parsing. A lot faster
3007 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3008 to the SKE that is used to indicate whether both of the SKE
3009 parties should perform authentication. By default only the
3010 responder performs authentication. By setting this flag also
3011 the initiator must do authentication. By default it is unset
3012 since in normal SKE case, client to server connection, only
3013 the responder should do authentication. When doing SKE between
3014 two clients both should perform authentication. Updated the
3015 code and the protocol specs.
3017 * A little fix to IDENTIFY command in the server. Search the
3018 client first by hash not nickname. Affected file is
3021 * Fixed the silc_client_close_connection to support closing
3022 the client to client connections wihtout deleting too much
3023 data. Affected file lib/silcclient/client.c.
3025 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3026 are received if protocol used to be active but is not anymore
3027 the application would crash due to NULL pointer dereference.
3028 Affected files silcd/server.c and lib/silcclient/client.c.
3030 * Added `hash' field to the SilcClientConnection to include
3031 the hash function negotiated in the SKE protocol.
3033 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3034 to set the channel founder authentication data. A client can
3035 claim the founder rights later by providing the authentication
3036 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3037 This way the channel founder can regain the channel founder
3038 privileges even it is left the channel. This works only on
3039 local server and the client must be connected to the same
3040 server to be able to regain the founder rights. Updated the
3041 protocol specs accordingly.
3043 Added support to the CMODE command in the client to set the
3044 founder auth data. Read the README to see how to set it.
3046 Added support to the CUMODE command to claim the founder
3047 rights. Read the README to see how to do it.
3049 Added support for the founder authentication to the Channel
3050 Entry in the server. Affected file silcd/idlist.h.
3052 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3053 server's CMODE command. Affected file silcd/command.c.
3055 * Added the following new functions into lib/silccore/silcauth.[ch]:
3056 silc_auth_get_method and silc_auth_get_data.
3058 * The server now saves the remote hosts public key to the
3059 SilcIDListData pointer. Affected file silcd/protocol.c.
3061 * The normal server now does not remove the channel entry from
3062 the cache if the founder authentication data is set. It used
3063 to remove it if the founder was the last one on the channel on
3064 the server and left the channel. The auth data is saved and
3065 if the channel is re-joined later the old entry is used with
3066 the old auth data. Affected files silcd/command_reply.c and
3069 * Removed the `pkcs' field from the SilcIDListData structure
3070 in the server; it is not used. Affected file silcd/idlist.h.
3072 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Fixed packet processing on slow links. Partial packets were
3075 never re-processed because the incoming data buffer was cleared
3076 by the application. Application must not directly clear the
3077 sock->inbuf, the packet processing routines handle it. Fixed
3078 this in client library and in server.
3080 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Fixed the WHOIS and IDENTIFY send reply function to really
3083 check whether to send list or just one entry. Affected file
3086 * Cleaned up the LEAVE command's channel key distribution. The
3087 affected file silcd/command.c.
3089 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3090 can enforce the channel mode as well. In that case the ID
3091 includes the ID of the server. The code now enforces the
3092 mode change if the router have different mode than the server.
3094 * The notify client operation with CMODE_CHANGE notify can now
3095 return NULL client_entry pointer if the CMODE was not changed
3096 by client. Application must check for this.
3098 * Added <Server ID> argument to INFO command to support server
3099 info fetching by Server ID.
3101 * Added silc_server_announce_get_channel_users to get assembled
3102 packets of channel users of the specified channel. Affected
3103 file silcd/server.[ch].
3105 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3106 was freed underneath the ID Cache.
3108 * Re-announce clients when the server received CHANNEL_CHANGE
3109 notify from the router. Affected file silcd/packet_send.c.
3111 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3114 crashed since it did not handle the fact that there is no cipher
3115 called "3" and didn't check the error condition. Now fixed.
3117 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3118 flag. It can be used to send message requests.
3120 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Implemented the RESTART command in the client.
3124 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3125 notice type messages. Added notice printing to the user
3128 * The channel keys are not re-generated if the channel's mode
3129 is PRIVKEY, ie private key on the channel exists. Affected
3130 files silcd/server.c and silcd/command.c.
3132 * Fixed a little bug in channel message delivery when channel
3133 private keys are set in the server. Affected file is
3134 silcd/packet_send.c.
3136 * Changed the setting on channel->on_channel = TRUE from the
3137 silc_client_save_channel_key to the JOIN command reply. The
3138 key payload is not received if the private channel key is set.
3139 Affected file lib/silcclient/command_reply.c and the
3140 lib/silcclient/client_channel.c.
3142 * When the CMODE_CHANGE notify is sent and the channel private
3143 key mode is removed the channel key must be re-generated in
3144 other cells as well. Added this support for the router in the
3145 silcd/packet_receive.c.
3147 * Added new local command NOTICE to send notice message on
3148 channel. Affected file silc/local_command.[ch].
3150 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Added new local command ME to the client. It is used to send
3153 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3154 some action. Affected file silc/local_command.[ch].
3156 * Changed channel_message and private_message client operations
3157 to deliver the message flags to the application. Added also
3158 the `flags' arguments to the silc_client_send_channel_message
3159 and silc_client_send_private_message functions. Affected file
3162 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Redefined the Private Message Payload to support private message
3165 keys and to support the new private message flags. Updated
3166 the protocol specs. Flags makes it possible to have for example
3167 CTCP style messages.
3169 * Added new type SilcPrivateMessagePayload and defined an API
3170 for it in the lib/silcclient/silcprivate.[ch].
3172 * Tested private message private keys successfully. Tested the
3173 private message key set, unset and list commands with the new
3176 * Redefined the Channel Message Payload to include the channel
3177 message flags (equal with private message flags) to support
3178 for example CTCP style messages.
3180 * Defined some of the message (for channel and private message)
3181 flags. Updated the protocol specs and added the flags to the
3182 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3184 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added SilcKeyAgreementStatus type to the key agreement routines
3187 to indicate the current status and error if one occured.
3188 The status types are defined in the lib/silcclient/silcapi.h.
3190 * Added new local command KEY that is used to set and unset private
3191 keys for channels, set and unset private keys for private messages
3192 with remote clients and to send key agreement requests and
3193 negotiate the key agreement protocol with remote client. The
3194 key agreement is supported only to negotiate private message keys,
3195 it currently cannot be used to negotiate private keys for channels,
3196 as it is not convenient for that purpose.
3198 * Fixed a minor pending callback setting bug in the function
3199 silc_client_get_client_by_id_resolve, now the function works.
3200 Affected file lib/silcclient/idlist.c.
3202 * Added function silc_net_get_local_port to get local bound
3203 port by socket. Added to lib/silcutil/silcnet.[ch].
3205 * Added `sockets' and `sockets_count' fields to the SilcClient
3206 object. They hold the sockets of the listenning sockets in
3207 the client. Listenning sockets may be for example the key
3208 agreement server. Affected file lib/silcclient/client.[ch].
3209 Added functions the silc_client_add_socket and the
3210 silc_client_del_socket. They are exported to the application
3213 * Added ~./silc/clientkeys to support other client's public keys.
3215 * Renamed verify_server_key client operation to verify_public_key
3216 and added one argument to indicate the type of the connection
3217 (server, client etc.).
3219 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * Added silc_server_connection_auth_request to handle the
3222 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3223 silcd/packet_receive.[ch].
3225 * Added silc_server_send_connection_auth_request into the
3226 silcd/packet_send.c to send the connection auth request packet.
3228 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3231 * Fixed the public key authentication in responder side in the
3232 server. The `auth_data' pointer includes the SilcPublicKey
3233 not the path to the public key. Affected file silcd/protocol.c.
3235 * Implemented the public key authentication in the initiator side
3236 in the server. Affected file silcd/protocol.c.
3238 * Removed the [RedirectClient] config section from the server
3239 configuration. Is not needed and I don't want to implement it.
3241 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Cleaned up the CMODE command in the server. It now works
3244 correctly and supports all the modes defined in the protocol.
3245 Affected file is silcd/command.c.
3247 * Added `hmac_name' field to the SilcChannelEntry in the server
3248 to hold the default HMAC of the channel. It can be set when
3249 creating the channel (with JOIN command). Affected files
3252 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3253 type to indicate the change of the current cipher and hmac
3254 on the channel. Client can safely ignore the <cipher> argument
3255 (if it chooses to do so) since the CHANNEL_KEY packet will
3256 force the channel key change anyway. The <hmac> argument is
3257 important since the client is responsible of setting the new
3258 HMAC and the hmac key into use.
3260 * Fixed the CMODE command in the client library as well.
3262 * Tested CMODE command in router environment successfully.
3264 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Show the version of the remote client (or server) when connecting
3267 to the server. It is logged to the log file. Affected file
3268 is silcd/protocol.c.
3270 * Fixed the KILLED notify handling in the client library. The
3271 client must be removed from all channels when receiving the
3274 Also, do not remove the client entry when giving the KILL
3275 command but when the KILLED notify is received.
3277 * Removed silc_idlist_find_client_by_nickname from the server.
3278 Not needed anymore. Affected files silcd/idlist.[ch].
3280 * Implemented the CHANNEL_CHANGE notify type handling to the
3281 server. Affected file silcd/server.c.
3285 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Added silc_server_send_notify_invite to send the INVITE
3288 notify between routers.
3290 * Implemented the INVITE command correctly to the server.
3292 * Implemented the INVITE notify type handling in the server.
3294 * Implemented the INVITE command to the client library and on the
3297 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added function silc_server_get_client_resolve to find the
3300 client entry by ID from all ID lists and then resolve it
3301 (using WHOIS) if it cannot be found. Affected file is
3304 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Implemented the BAN command to the client library.
3308 * The JOIN command in the server now checks the invite list
3311 * Changed the silc_command_reply_payload_encode_va and the
3312 silc_command_payload_encode_va to support that if argument is
3313 NULL it ignores and checks the next argument. Affected file
3314 lib/silccore/silccommand.c.
3316 * Added silc_server_send_notify_ban to send the BAN notify
3317 type between routers.
3319 * Chaned the silc_notify_payload_encode to support that if
3320 argument is NULL it ignores and checks the next argument.
3321 Affected file lib/silccore/silcnotify.c.
3323 * Tested ban lists in router environment successfully.
3325 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Implemented BAN command to the server, in silcd/command.[ch].
3329 * Removed the BAN and INVITE_LIST modes from the CMODE command
3332 * Added function silc_string_match to regex match two strings.
3333 Affected files lib/silcutil/silcutil.[ch].
3335 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Redefined parts of the SilcChannelEntry in the server to support
3338 the new ban and invite lists.
3340 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Redefined the INVITE command. The same command can be used to
3343 invite individuals to the channel but also to manage the invite
3344 list of the channel (to add to and remove from the invite list).
3345 Updated the protocol specs.
3347 * Added new command SILC_COMMAND_BAN that can be used to manage
3348 the ban list of the channel. Updated the protocol specs.
3350 * Removed the channel modes: the SILC_CMODE_BAN and the
3351 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3352 in the CMODE command. The equivalent features are now available
3353 using INVITE and BAN commands. Updated the protocol specs.
3355 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3356 in the network about change in the current ban list. The notify
3357 type is not used by the client.
3359 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3360 support the invite lists.
3362 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Added new function silc_string_regexify that converts string
3365 including wildcard characters into regex string that can
3366 be used by the GNU regex library. Added into the file
3367 lib/silcutil/silcutil.[ch].
3369 Added silc_string_regex_combine to combine to regex strings
3370 into one so that they can be used as one regex string by
3371 the GNU regex library. Added into the file
3372 lib/silcutil/silcutil.[ch].
3374 Added silc_string_regex_match to match two strings. It returns
3375 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3377 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Imported GNU regex to the soruce tree into lib/contrib.
3380 Fixed some compiler warning from the regex.c.
3382 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3384 * Fixed MOTD command in the server to work in router environment.
3386 * Fixed the MOTD command in the client library to support
3387 the server argument in the command.
3389 * Added `nickname_len' argument to the silc_idlist_add_client
3390 in the server, as the `nickname' argument may be binary data
3393 * Added silc_idlist_get_channels to return all channels from
3396 * Implemented LIST command to the server. Affected file is
3399 * Implemented the LIST command to the client library and on the
3402 * Added [<user count>] argument to the LIST command reply.
3403 With private channels the user count is not shown.
3405 * Updated TODO and README.
3407 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * The client entry's data.registered must be TRUE even with
3410 global client entry on global client list. The data.registered
3411 is used to check whether the client is anymore in the network,
3412 for example with WHOWAS command so it must be valid.
3414 * Fixed the WHOWAS command in the server. It now actually works
3415 in router environment. Added function into silcd/command_reply.c
3416 silc_server_command_reply_whowas_save.
3418 * Added silc_idlist_purge function to the silcd/idlist.c
3419 to periodically purge the ID Cache.
3421 * Fixed INFO command in the server. It works now in router
3422 environment. Added <server name> argument to the INFO command
3423 reply. Updated the protocol specs.
3425 * Fixed minor bug in silc_idcache_purge to not purge if the
3426 expire value is zero.
3428 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3429 they were buggy because of the WHOWAS information.
3431 * Fixed local command MSG to handle the async resolving of
3432 the remote client properly. It used to fail the first MSG.
3433 Affected file silc/local_command.c.
3435 * Added `data_len' field to SilcIDCache context.
3437 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Update TODO. Todo in commands in the server.
3441 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3444 used by routers as broadcast packet to inform other routers
3445 about the changed user mode.
3447 Implemented the notify handling in the server. Affected file is
3448 silcd/packet_receive.c. Added the function
3449 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3451 * Added new generic Channel Payload and deprecated the New Channel
3452 Payload. The New Channel Payload is now the generic Channel
3455 * Added new argument `mode' to the silc_server_send_new_channel
3456 as it is required in the Channel Payload now.
3458 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3459 and created a new and real SilChannelPayload to represent the
3460 new generic Channel Payload. Implemented the encode/decode
3461 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3463 * Added silc_server_get_client_channel_list to return the list
3464 of channels the client has joined for WHOIS command reply.
3465 Affected file silcd/server.[ch].
3467 * Implemented the channel list sending in the WHOIS command reply
3468 in server and in the client.
3470 Implemented the channel list displaying on the user interface
3471 as well. Affected file silc/client_ops.c.
3473 * Added silc_channel_payload_parse_list to parse list of Channel
3474 Payloads. It returns SilcDList list of SilcChannelPayloads.
3475 Client for example can use this function to parse the list of
3476 channels it receives in the WHOIS command reply. The caller
3477 must free the list by calling silc_channel_payload_list_free.
3478 Affected files lib/silccore/silcchannel.[ch].
3480 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Added one new argument <user mode> to the WHOIS command reply
3483 to return the mode of the user in SILC. Updated the protocol
3486 Implemented it to the server and client.
3488 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Fixed the mode printing on the user interface on joining.
3491 Affected file silc/client_ops.c.
3493 * Implemented the UMODE command and user modes in general to the
3494 client library and to the user interface.
3496 * Implemented the UMODE command to the server.
3498 * The server now sends UNKNOWN_COMMAND error status if client sends
3499 unknown command. Affected file silcd/command.c.
3501 * All server commands now handle the command identifier the right
3502 way when sending the command reply to the client. The client can
3503 use to identify the command replies with the identifier.
3505 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Added silc_server_get_client_route to resolve the route to
3508 the client indicated by the client ID. Affected file is
3511 * Added silc_server_relay_packet as general function to relay
3512 packet to arbitrary destination. This deprecates functions
3513 like _send_private_message_key, _relay_notify etc. Affected
3514 file is silcd/packet_send.[ch].
3516 Removed silc_server_send_key_agreement,
3517 silc_server_send_private_message_key and
3518 silc_server_packet_relay_notify functions from the file
3519 silcd/packet_send.[ch].
3523 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3524 server. Affected file silcd/packet_receive.[ch].
3526 * Implemented the KILL command to the client. Implemented the
3527 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3528 Affected files lib/silcclient/command[_reply].c and
3529 lib/silcclient/client_notify.c. Implemented the KILL notify
3530 printing in the user inteface.
3532 * Fixed a lot silc_parse_nick memory leaks from the client
3533 library in the file lib/silcclient/command.c.
3535 * Changed the silc_server_send_notify_on_channels's `sender'
3536 argument from SilcSocketConnection to SilcClientEntry to
3537 check the sender as entry and not as connection object and not
3538 to send to the client provided as argument. The affected file
3539 is silcd/packet_send.[ch].
3541 * The notify packets that are destined directly to the client used
3542 to not to be processed by the server. Now changed that and the
3543 server processes all notify packets. After relaying the packet
3544 to the client the notify packet is processed in the server.
3546 * The silc_server_free_client_data now checks whether there is
3547 pending outgoing traffic for the client and purges the data to
3548 the network before removing the client entry.
3550 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3553 an client is killed from the SILC Network. Updated the protocol
3556 Added new function silc_server_send_notify_killed to the
3557 silcd/packet_send.[ch].
3559 * Added function silc_server_packet_relay_notify to relay notify
3560 packets that are destined directly to a client. In this case
3561 the server does not process the notify packets but merely relays
3562 it to the client. Affected file silcd/packet_send.[ch].
3564 Added also silc_server_packet_process_relay_notify to check
3565 whereto relay the notify. Affected file is
3566 silcd/packet_receive.[ch].
3568 * Implemented the KILL command to the server.
3572 * Added the backup schema desgined last fall to the protocol
3573 specs for everyone to see. The specification is in the
3574 *-spec-xx.txt draft and the packet type definitions for the
3575 backup routers is in *-pp-xx.txt draft. Thusly, added also
3576 new packet type SILC_PACKET_CELL_ROUTERS.
3578 * A big security problem in the implementation discovered. The
3579 signoff of an client did not cause new channel key generation
3580 which it of course should've done. The channel keys must be
3581 always re-generated when client leaves (or signoffs) the channel.
3582 The silc_server_remove_from_channels funtion now handles
3583 the channel key re-generation.
3585 * Added `sender' argument to the silc_server_send_notify_on_channels
3586 to not to send the client provided as argument. Affected file
3587 silcd/packet_send.[ch].
3589 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Implemented OPER and SILCOPER commands into the server and
3594 * Added silc_auth_verify and silc_auth_verify_data to verify
3595 the authentication directly from the authentication payload.
3596 It supports verifying both passphrase and public key based
3597 authentication. Affected file lib/silccore/silcauth.[ch].
3599 * Added `hash' field to the SilcIDListData structure. It is the
3600 hash negotiated in the SKE protocol. Affected file is
3603 * Slight redesigning of the SilcAuthPayload handling routines.
3604 Do not send SilcPKCS but SilcPublicKey as argument.
3606 * Implemented the public key authentication support to the
3607 serverconfig. The public key is loaded from the provided path
3608 and saved as authentication data to void * pointer. Thus,
3609 changed the unsigned char *auth_data to void *auth_data;
3611 * Fixed SHUTDOWN command to send the reply before the server
3612 is shutdown. :) Affected file silcd/command.c.
3614 * Fixed fatal bug in CONNECT command. The hostname was invalid
3615 memory and server crashed. Affected file silcd/command.c.
3617 * Fixed fatal bug in CLOSE command. The server_entry became
3618 invalid but was referenced later in the command. Affected file
3621 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Fixed fatal bug in failure packet handling. Server ignored
3624 the failure and thus crashed when it came.
3628 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3631 that the command may be executed only once in (about) 2 seconds.
3632 The old SILC_CF_LAG flag is same but allows command bursts up
3633 to five before limiting.
3635 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3636 server code. Various commands now includes the CF_LAG_STRICT
3637 flag to disallow any kind of miss-use of the command.
3639 * Fixed the silc_buffer_unformat to not to allocate any data
3640 if the length of the data is zero. It used to allocate the
3641 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3643 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Changed the format of AdminConnection configuration section
3646 in the server. Added username of the admin to the format.
3647 Affected files silcd/serverconfig.[ch].
3649 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3650 to return admin configuration data by host, username and/or
3653 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Implemented WHOWAS command to the server. Added the functions:
3657 silc_server_command_whowas_parse,
3658 silc_server_command_whowas_send_reply,
3659 silc_server_command_whowas_from_client and
3660 silc_server_command_whowas_from_server
3662 * Added <Client ID> argument to the WHOWAS command reply. Updated
3663 the protocol specs accordingly.
3665 * Implemented WHOWAS command and command_reply to the client
3668 Implemented the WHOWAS printing on the user interface.
3670 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added new argument to the WHOWAS command reply, the real name.
3673 It is an optional argument. Updated the protocol specs.
3675 * Added SilcIDCacheDestructor callback that is registered when
3676 the SilcIDCache is allocated. The callback is called when
3677 an cache entry in the ID Cache expires, or is purged from the
3678 cache. Added into lib/silccore/idcache.[ch].
3680 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3681 to destruct the client entries when the cache entry expires.
3682 Other ID Cache's in server and in the client library ignores
3685 * If the ID Cache entry's `expire' field is zero then the entry
3686 never expires. Added boolean `expire' argument to the
3687 silc_idcache_add function in the lib/silccore/idcache.[ch].
3688 If it is TRUE the default expiry value is used.
3690 * Added silc_server_free_client_data_timeout that is registered
3691 when client disconnects. By default for 5 minutes we preserve
3692 the client entry for history - for WHOWAS command.
3694 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Added support to the server to enforce that commands are not
3697 executed more than once in 2 seconds. If server receives
3698 commands from client more frequently, timeout is registered
3699 to process the commands. Affected file silcd/command.c.
3700 Added new function silc_server_command_process_timeout.
3702 * Changed NICK_NOTIFY handling in client library to check that
3703 if the client's nickname was changed, so there is no need to
3704 resolve anything from the server.
3706 * Removed error printing from the WHOIS and IDENTIFY commands.
3707 If error occurs then it is ignored silently in the client library.
3708 The application, however, may map the received error to
3709 human readable error string. The application currently maps
3710 the NO_SUCH_NICKNAME error to string.
3712 * Made the command status message public to the application. Moved
3713 them from lib/silcclient/command_reply.c to
3714 lib/silcclient/command_reply.h. The application can map the
3715 received command status to the string with the
3716 silc_client_command_status_message function.
3718 * Added check to the server to check that client's ID is same
3719 as the Source ID in the packet the client sent. They must
3722 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Added dist-bzip hook to the Makefile.am to make bzip2
3725 compressed distributions.
3727 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Server now enforces the maximum length for the nickname and
3730 the channel as protocol specification dictates. 128 bytes for
3731 nickname and 256 bytes for channel name.
3733 * Moved the WHOIS printing to the application. The client libary
3734 does not print out the WHOIS information anymore, the application
3735 must do it. Renamed silc_client_command_reply_whois_print to
3736 the silc_client_command_reply_whois_save.
3738 The client's idle time is also sent to the application now, and
3739 the idle is shown on screen.
3741 * Added silc_client_command_reply_identify_save to save the
3742 received IDENTIFY entries.
3744 * Do not check for channel private keys in message sending and
3745 reception if the channel does not have the PRIVKEY mode set.
3746 Affected file lib/silclient/client_channel.c.
3748 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3751 just surfaced after chaning the JOIN procedure.
3753 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Added silc_client_get_clients_by_list to get client entries
3756 from Client ID list, that is returned for example by JOIN
3757 and USERS command replies. The application should use this
3758 function for example when JOIN command reply is received to
3759 resolve the clients already on the channel (library does not
3760 do that anymore as USERS command reply is not used in the JOIN
3761 procedure anymore). Affected files lib/silcclient/silcapi.h and
3762 lib/silcclient/idlist.c.
3764 * JOIN command reply and USERS command reply returns now SilcBuffer
3765 pointers instead of unsigned char pointers when returning
3766 the client list and mode list.
3768 * Added <Client ID> argument to the JOIN command reply, mainly
3769 for the server to identify for which client the command was
3770 originally sent. Updated protocol specs accordingly.
3772 * Added SilcDlist private_key pointer to the SilcChannelEntry
3773 in the client to support the channel private keys. Affected
3774 file is lib/silcclient/idlist.h.
3776 * Added SilcChannelPrivateKey argument to the function
3777 silc_client_send_channel_message so that application can choose
3778 to use specific private ke if it wants to. If it is not provided,
3779 the normal channel key is used, unless private keys are set.
3780 In this case the first (key that was added first) is used
3781 as the encryption key.
3783 * Implemented the support for channel private key handling.
3784 Implemented the following functions:
3786 silc_client_add_channel_private_key,
3787 silc_client_del_channel_private_keys,
3788 silc_client_del_channel_private_key,
3789 silc_client_list_channel_private_keys and
3790 silc_client_free_channel_private_keys
3792 Affected file lib/silcclient/client_channel.c.
3794 * Added the support for the private keys in the channel message
3795 sending and encryption and in the message reception and
3796 decryption. Affected funtions are
3797 silc_client_send_channel_message and silc_client_channel_message.
3799 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Added SKE's key verify callback to the client library's
3802 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3804 * Removed the statement that server (or router) must send USERS
3805 command reply when joining to the channel so that the client
3806 knows who are on the channel. Instead, the client list and
3807 client's mode list is now sent in the JOIN command reply to the
3808 client who joined channel. This is better solution.
3810 * Added function silc_server_get_users_on_channel and function
3811 silc_server_save_users_on_channel to the silcd/server.[ch].
3813 * Removed function silc_server_command_send_users from the
3816 * Do not show topic on the client library anymore. The topic is
3817 sent in the command reply notify to the application and the
3818 application must show the topic now.
3820 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Added client searching by nickname hash into the IDENTIFY and
3823 WHOIS commands in the server as they were clearly missing from
3824 them. Affected file is silcd/command.c.
3826 * Fixed a bug in private message receiving in the client library.
3827 The remote ID was freed and it wasn't supposed, now it is
3830 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Minor fix to the channel payload; allocate the data area, as it
3833 needs to be of specific length.
3835 * If the key agreement port is zero then the operating
3836 system will define the bound port. Affected files are
3837 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3839 * Added new function silc_channel_payload_decrypt into the file
3840 lib/silccore/silcchannel.[ch].
3842 * Moved the channel message etc, check from silc_packet_decrypt
3843 to applications. The library calls now a generic
3844 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3845 when the packet is either normal or special. This was done to
3846 allow more wide range of checking that was not allowed when
3847 the code was in library. Now applications can do virtually any
3848 checks to the packet and return to the library the decision how
3849 the packet should be processed. Affected files are
3850 lib/silccore/silcpacket.[ch].
3852 Added silc_server_packet_decrypt_check to the server and
3853 silc_client_packet_decrypt_check to the client library.
3855 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3856 to send with specified source and destination information.
3858 * Channel message delivery between routers was broken after the
3859 channel key distribution was fixed earlier. The channel key
3860 was used be to distributed to other routers as well which is not
3861 allowed by the protocol. Now this is fixed and channel keys
3862 really are cell specific and the channel message delivery between
3863 routers comply with the protocol specification.
3865 * Fixed various commands in server to check also the global list
3866 for the channel entry and not just the local list. The affected
3867 file silcd/command.c.
3869 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Added assert()s to buffer formatting and unformatting routines
3872 to assert (if --enable-debug) when error occurs. Affected
3873 file: lib/silcutil/silcbuffmt.c.
3875 * Changed to auto-reconnect to check whether the remote host is
3876 router and register the re-connect timeout if it is. It used
3877 to check that whether we are normal server, but router must do
3878 auto-reconnect with another router as well. Affected file
3881 * Removed the [<key len>] option from CMODE command as the cipher
3882 name decides the key length, nowadays. See the defined ciphers
3883 from the protocol specification.
3885 * Added [<hmac>] option to the CMODE command to define the HMAC
3886 for the channel. Added SILC_CMODE_HMAC channel mode.
3888 * Added [<hmac>] option for the JOIN command so that user can
3889 select which HMAC is used to compute the MACs of the channel
3892 * Added Hmac field to the Channel Message Payload. The integrity
3893 of plaintext channel messages are now protected by computing
3894 MAC of the message and attaching the MAC to the payload. The
3895 MAC is encrypted. Now, it is clear that this causes some
3896 overhead to the size of the packet but rationale for this is that
3897 now the receiver can verify whether the channel message decrypted
3898 correctly and also when private keys are set for the channel the
3899 receiver can decrypt the packet with several keys and check from
3900 the MAC which key decrypted the message correctly.
3902 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3903 lib/silccrypt/silccipher.[ch].
3905 * Added silc_hash_len to return the digest length into the
3906 lib/silcrypt/silchash.[ch].
3908 * Rewrote parts of Silc Channel Payload interface in the
3909 lib/silccore/silcchannel.[ch]. The encode function now also
3910 encrypts the packet and parse function decrypts it.
3912 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Fixed a minor formatting bug in the SKE's key material processing.
3915 It actually might have processed the keys wrong way resulting
3918 * Redefined the mandatory HMAC algorithms and added new algorithms.
3919 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3920 and hmac-md5 truncated to 96 bits. The mandatory is now
3921 hmac-sha1-96. Rest are optional (including the one that used
3922 to be mandatory). Rationale for this is that the truncated HMAC
3923 length is sufficient from security point of view and can actually
3924 make the attack against the HMAC harder. Also, the truncated
3925 HMAC causes less overhead to the packets. See the RFC2104 for
3928 * Added new [hmac] configuration section. The SKE used to use
3929 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3930 is of course wrong. The official names that must be proposed in
3931 the SKE are the ones defined in the protocol specification
3932 (hmac-sha1-96 for example). The user can configure any hmac
3933 using any hash function configured in the [hash] section. At
3934 least, the mandatory must be configured.
3936 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3938 * Added HMAC list to the SKE proposal list. It has now both
3939 hash algorithm list and HMAC list. This makes the protocol
3940 incompatible with previous versions. The SKE now seems to work
3941 the way it is supposed to work, for the first time actually.
3943 * Defined plain Hash algorithms to the protocol specification.
3946 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Implemented support for key agreement packets into the server.
3949 Added functions silc_server_key_agreement and
3950 silc_server_send_key_agreement. Other than these functions,
3951 server has nothing to do with this packet.
3953 * Added support for private message key packets into the server.
3954 Added functions silc_server_private_message_key and
3955 silc_server_send_private_message_key.
3959 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3960 called in the protocol's final callback instead in the END
3961 protocol state. This makes a little more sense and in the same
3962 time in client we can use the same protocol routines for normal
3963 key exchange and to key agreement packet handling as well.
3965 * Added to both client's and server's KE protocol context the
3966 SilcSKEKeyMaterial pointer to save the key material. We will
3967 bring the key material to the protocol's final callback by doing
3968 this. The final callback must free the key material.
3970 * Added SKE's packet_send callback into client's KE protocol
3971 context so that the caller can choose what packet sending function
3972 is used. This way we can use different packet sending when
3973 doing normal SKE when doing key agreement packet handling (in
3974 the key agreement packet handling we do not want to encrypt
3977 * Implemented the responder side of the key agreement routines
3978 in the client. The client can now bind to specified port and
3979 accept incoming key negotiation. The key material is passed
3980 to the application after the protocol is over.
3982 * Implemented the processing of incoming Key Agreement packet
3983 in the client. Added function silc_client_key_agreement to
3986 * Implemented the intiator side of the key agreement routines
3987 in the client. The client can now initiate key agreement with
3988 another remote client. The key material is passed to the
3989 application after the protocol is over.
3991 * Created client_keyagr.c to include all the key agreement
3994 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3995 SILC_TASK_CALLBACK except that it is not static.
3997 * Created client_notify.c and moved the Notify packet handling
3998 from the client.[ch] into that file.
4000 * Created client_prvmsg.c and moved all private message and
4001 private message key routines from the client.[ch] into that file.
4003 * Create client_channel.c and moved all channel message and
4004 channel private key routines from the client.[ch] into that file.
4006 * Changed silc_client_get_client_by_id_resolve to resolve with
4007 WHOIS command instead of IDENTIFY command, in the file
4008 lib/silclient/idlist.c.
4010 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Implemented the SKE's responder side to the Client library.
4014 * When FAILURE is received to the protocol do not trust it
4015 blindly. Register a timeout to wait whether the remote closes
4016 the connection as it should do it, only after that process the
4017 actual failure. This was changed to both client and server.
4019 * Added client_internal.h to include some of the structures
4020 there instead of client.h in lib/silcclient/.
4022 * Added function silc_task_unregister_by_callback to unregister
4023 timeouts by the callback function.
4025 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Some "Incomplete WHOIS info" errors has been appearing on the
4028 log files. Took away the entry->userinfo check from WHOIS
4029 reply sending. The entry->userinfo is now " " if client did not
4030 provide one. I thought this was fixed earlier but something
4031 is wrong still. Let's see if the error still appears.
4033 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Fixed a minor bug in the login when the channel key is
4036 re-generated in the server. It used to generate the key in
4037 wrong order and thus caused problems in the channel traffic.
4039 * Fixed a minor bug in channel key distsribution after
4040 KICK command. The key was not sent to the router even though
4043 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Added silc_ske_process_key_material_data as generic routine
4046 to process any key material as the SILC protocol dictates. The
4047 function is used by the actual SKE library but can be used by
4048 applications as well. This relates to the private message keys
4049 and the channel private keys since they must be processed the
4050 same way the normal SILC session keys. The protocol dictates
4051 this. Affected files: lib/silcske/silcske.[ch].
4053 Added also silc_ske_free_key_material to free the
4054 SilcSKEKeyMaterial structure.
4056 * Defined silc_cipher_set_key function to set the key for
4057 cipher without using the object's method function. The affected
4058 files: lib/silccrypt/silccipher.[ch].
4060 * Implemented silc silc_client_add_private_message_key,
4061 silc_client_add_private_message_key_ske,
4062 silc_client_del_private_message_key,
4063 silc_client_list_private_message_keys and
4064 silc_client_free_private_message_keys functions in the
4067 Added functions silc_client_send_private_message_key to send
4068 the Private Message Key payload and silc_client_private_message_key
4069 to handle incoming Private Message Key payload.
4071 * Added Cipher field to the Private Message Key payload to set
4072 the cipher to be used. If ignored, the default cipher defined
4073 in the SILC protocol (aes-256-cbc) is used.
4075 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Removed lib/silcclient/ops.h file.
4079 Redefined parts of the SILC Client Library API. Created new
4080 file silcapi.h that deprecates the ops.h file and defines the
4081 published Client Library API. Defined also private message key
4082 API and channel private key API into the file.
4084 This is the file that the application must include from the
4085 SILC Client Library. Other files need not be included by
4086 the application anymore.
4088 * Added new key_agreement client operation callback and also
4089 defined the Key Agreement library API for the application.
4091 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4094 is used by clients to request key negotiation between another
4095 client in the SILC network. If the negotiation is started it
4096 is performed using the SKE protocol. The result of the
4097 negotiation, the secret key material, can be used for example
4098 as private message key.
4100 Implemented the Key Agreement payload into the files
4101 lib/silccore/silauth.[ch].
4103 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Redefined ciphers for the SILC protocol. Added some new ciphers
4106 and defined the key lengths for the algorithms. Changed the
4107 code accordingly. The default key length is now 256 bits.
4109 * Fixed SKE key distribution function silc_ske_process_key_material
4110 when the key length is more than 128 bits. The default key
4111 length in SILC is now 256 bits.
4113 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4114 to indicate unsupported algorithm.
4116 * Renamed rijndael.c to aes.c and all functions as well.
4118 * Fixed a long standing channel key setting bug in client library.
4119 Weird that it has never surfaced before.
4121 * Fixed bug in channel deletion. If the entire channel is removed
4122 then it must also delete the references of the channel entry
4123 from the client's channel list as the client's channel entry and
4124 the channel's client entry share same memory.
4126 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Implemented CONNECT and SHUTDOWN commands in the client.
4130 * Implemented CLOSE command to the client.
4132 * Added the function silc_idlist_find_server_by_name into the
4133 files silcd/idlist.[ch].
4135 Added the function silc_idlist_find_server_by_conn into the
4136 files silcd/idlist.[ch].
4138 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * DIE command was renamed to SHUTDOWN. Updated the both code
4143 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4144 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4146 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4149 * Added function silc_server_create_connection function to create
4150 connection to remote router. My server implementation actually
4151 does not allow router to connect to normal server (it expects
4152 that normal server always initiates the connection to the router)
4153 so the CONNECT command is only good for connecting to another
4156 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4159 or some other client was kicked from the channel.
4161 Implemented the handling of the notify type to both client
4164 Implemented silc_server_send_notify_kicked to send the KICKED
4165 notify. It is used to send it to the server's primary router.
4167 * Implemented the KICK command into server and client.
4169 * Added `query' argument to the silc_idlist_get_client function
4170 to indicate whether to query the client from server or not if
4173 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4174 to indicate that the client is not channel founder.
4178 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Removed the rng context from SilcPacketContext structure and
4181 changed that the packet routine uses the Global RNG API.
4183 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Added support for quit message that client can "leave" on the
4186 channel when it quits the SILC. It is ditributed inside the
4187 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4189 Added silc_server_free_client_data that will take the
4190 signoff message as argument.
4192 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4194 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Updated parts of the protocol specification to keep it up
4199 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4202 payloads in one packet.
4204 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4205 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4206 use now the new List flag.
4208 * Also deprecated the following packet types: REPLACE_ID,
4209 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4211 * Added list support for Notify packet in server.
4213 * Added silc_server_send_notify_channel_change to send the
4214 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4215 the silc_server_send_replace_id.
4217 * Added silc_server_send_notify_nick_change to send the
4218 NICK_CHANGE notify type. Deprecates the function
4219 silc_server_send_replace_id.
4221 * Added silc_server_send_notify_join to send the JOIN notify type.
4222 Deprecates the function silc_server_send_new_channel_user.
4224 * Added silc_server_send_notify_leave to send LEAVE notify type.
4225 Deprecates the function silc_server_send_remove_channel_user.
4227 * Added silc_server_send_notify_cmode and
4228 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4229 types. Deprecates the silc_server_send_set_mode function.
4231 * Added SERVER_SIGNOFF notify type to indicate that server has
4232 quit. This means that all clients on the channel from that
4233 server will drop. This can be also used when netsplit happens.
4235 Deprecated REMOVE_ID packet type since it is not needed anymore
4238 Added silc_server_send_notify_server_signoff to send the
4239 SERVER_SIGNOFF notify type. Deprecates the function
4240 silc_server_send_remove_id.
4242 Added also silc_server_send_notify_signoff to send the
4243 SIGNOFF notify type.
4245 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4246 SILC protocol from this day on. Changed the protocol
4247 specification as well.
4249 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4250 notify type. It is used between routers to notify about
4251 topic changes on a channel.
4253 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4256 * Partly updated the protocol specification to comply with the
4257 changes now made. It is still though a bit outdated.
4259 * The JOIN notify type now takes one extra argument <Channel ID>.
4260 The packet used to be destined to the channel but now the
4261 JOIN type may be sent as list thus it is impossible to
4262 destine it to any specific channel. By adding this argument
4263 it is again possible.
4265 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Added CREDITS file. The CHANGES and CREDITS file will appear
4268 in the distribution as well.
4270 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4273 types in the server's silcd/packet_receive.c.
4275 * Implemented CMODE and CUMODE to work in router environment.
4277 * Fixed minor encoding and decoding buglet from the
4278 lib/silccore/silcmode.c.
4280 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4283 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4285 * Changed all SilcConfigServer* and silc_config_server* to
4286 SilcServerConfig* and silc_server_config*, respectively.
4289 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Associated the ID (client or server ID) to the Authentication
4292 Payload to avoid any possibility of forging. Updated the
4293 protocol specification and the code accordingly.
4295 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * The RSA key length is now save to the RsaKey context in the
4298 key generation process in lib/silccrypt/rsa.c. The key length
4299 is now used to figure out the maximum size of the block allowed
4300 to be encrypted/signed.
4302 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4303 is equivalent to the silc_mp_mp2bin but does not allocate any
4306 * Changed silc_mp_mp2bin API to take length argument. If it is
4307 non-zero then the buffer is allocated that large. If zero, then
4308 the size is approximated using silc_mp_sizeinbase, which however
4311 * Created Global RNG API which is global RNG that application can
4312 initialize. After initializing, any routine anywhere in the
4313 code (including library) can use RNG without allocating a new
4314 RNG object. This was done to allow this sort of use of the
4315 RNG in code that has no chance to allocate RNG object. All
4316 applications currently allocate this and many routines in the
4317 library use this. Affected file lib/silccrypt/silcrng.[ch].
4319 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4320 it to use the Global RNG API.
4322 * Defined Authentication Payload into protocol specification that
4323 is used during SILC session to authenticate entities. It is
4324 used for example by client to authenticate itself to the server
4325 to obtain server operator privileges.
4327 Implemented this payload into the lib/silccore/silcauth.[ch].
4328 Implemented also routines for public key based authentication
4329 as the new protocol specification dictates.
4331 Moved definitions of different authentication methods from
4332 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4334 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4335 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4336 silc_pkcs_verify_with_hash functions into the file
4337 lib/silccrypt/silcpkcs.[ch].
4339 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * The client entry's userinfo pointer must be always valid.
4342 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4343 will fail since it requires the userinfo. Now, the userinfo
4344 is allocated as "" if actual userinfo does not exist. Actually,
4345 it must exist and it is totally Ok to drop client connections
4346 that does not announce the userinfo. However, we will make
4347 this workaround for now.
4349 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4350 to return the remote port by socket.
4352 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4355 SILC_SERVER_PENDING_EXEC and added an new macro
4356 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4357 data or when error occurs while processing the pending command.
4359 Added new argument `destructor' into silc_server_command_pending
4360 and to the SilcServerCommandPending object. This destructor is
4361 now called after calling the pending callback or if error occurs
4362 immediately. If error occurs the actual pending callback won't
4363 be called at all - only the destructor. The destructor may be
4364 NULL if destructor is not needed.
4366 All this applies for client library code as well. Similar
4367 changes were made there as well for the pending commands.
4369 In the client, the application must now allocate the
4370 SilcClientCommandContext with the silc_client_command_alloc
4373 * Added reference counter to the SilcServerCommandContext. Added
4374 function silc_server_command_alloc and silc_server_command_dup
4377 Same type of functions added to the client library for the same
4380 * Removed the cmd_ident from IDListData away since it is now
4381 global for all connections. It is the command identifier used
4382 in command sending and with pending commands. The affected file
4385 * Added reference counter to the SilcSocketConnection objecet to
4386 indicate the usage count of the object. The object won't be
4387 freed untill the reference counter hits zero. Currently only
4388 server uses this, and client ignores it. The client must be
4389 set to use this too later. The affected files are
4390 lib/silccore/silcsockconn.[ch]. Added also the function
4391 silc_socket_dup to increase the reference counter.
4393 This was mainly added because it is possible that the socket
4394 is removed underneath of pending command or other async
4395 operation. Now it won't be free'd and proper DISCONNECTING
4396 flags, etc. can be set to avoid sending data to connection that
4397 is not valid anymore.
4399 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4400 the connection. After that it sets SILC_SET_DISCONNECTED.
4401 It is, however, possible that the socket data is not still freed.
4402 The silc_server_packet_process now checks that data is not
4403 read or written to connection that is DISCONNECTED. The socket
4404 get's freed when the reference counter hits zero.
4406 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Changed the client operation API: channel_message operation's
4409 `sender' is now the client entry of the sender, not the nickname
4410 and the `channel' is the channel entry, not the channel name.
4412 In the private_message operation the `sender' is now also the
4413 client entry of the sender not the nickname.
4415 Affected file is lib/silcclient/ops.h and all applications
4416 using the client operations.
4418 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Moved the calling of ops->connect() from connect_to_server_final
4421 into receive_new_id functin since that is the point when the
4422 client is actually allowed to send traffic to network. The
4423 affected file is lib/silcclient/client.c.
4425 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4428 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4429 (if needs broadcasting) instead of broadcasting the packets one
4430 by one which would make a burst in the network traffic.
4432 * Added `broadcast' argument to the functions in silcd/server.[ch]
4433 silc_server_create_new_channel[_with_id] to indicate whether
4434 to send New Channel packet to primary router.
4436 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Added new function into the silcd/server.[ch] files:
4439 silc_server_create_new_channel_with_id to create new channel with
4440 already existing Channel ID.
4442 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4443 lib/silccore/silcpacket.h. This packet is used t send list of
4444 Set Mode payloads inside one packet. Server uses this to set
4445 the modes for the channels and clients on those channels, that it
4446 announced to the router when it connected to it. The protocol
4447 specification has been updated accordingly.
4449 * The silc_server_new_channel did not handle the packet coming
4450 from normal server as it normally does not send that. However,
4451 when it announces its channels it does send it. Implemented
4452 the support for that.
4454 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4455 into the file lib/silccore/id.h.
4457 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Fixed memory leaks in the functions silc_idlist_del_client,
4460 silc_idlist_del_channel and silc_idlist_del_server in the file
4461 silcd/idlist.c. All of those leaked like a sieve.
4463 * Fixed some small memory leaks in the client's function
4464 silc_client_notify_by_server.
4466 * Added functions into silcd/server.c: silc_server_announce_clients,
4467 silc_server_announce_channels and silc_server_announce_server.
4468 These functions are used by normal and router server to announce
4469 to its primary router about clients, channels and servers (when
4470 router) that we own. This is done after we've connected to the
4473 These functions effectively implements the following packet types:
4474 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4475 and SILC_PACKET_NEW_ID_LIST.
4477 * Added new functions into the silcd/packet_receive.[ch]:
4478 silc_server_new_id_list, silc_server_new_channel_list and
4479 silc_server_new_channel_user_list to handle the incoming
4480 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4482 * Added support of changing Channel ID in the function
4483 silc_server_replace_id. If the server that announces a channel
4484 to the router already exists in the router (with same name but
4485 with different Channel ID), router is responsible to send
4486 Replace ID packet to the server and force the server to change
4487 the Channel ID to the one router has.
4489 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4490 client that the Channel ID has been changed by the router. The
4491 normal server sends this to the client. Client must start using
4492 the new Channel ID as the channel's ID.
4494 Implemented handling of this new type into lib/silcclient/client.c
4495 into the function silc_client_notify_by_server.
4497 * Added new function silc_idlist_replace_channel_id into the files
4498 silcd/idlist.[ch] to replace the Channel ID.
4500 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Call silc_server_command_identify_check always when processing
4503 the IDENTIFY command in silcd/command.c
4505 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4508 send keepalive packets. The packet can be sent by clients,
4509 servers and routers.
4511 Added function silc_socket_set_heartbeat into the file
4512 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4513 If not set, the heartbeat is not performed. The actual
4514 heartbeat is implemented in the low level socket connection
4515 library. However, application is responsible of actually
4518 Added silc_server_send_heartbeat to send the actual heartbeat
4519 packet into silcd/packet_send.[ch]. Server now performs
4520 keepalive with all connections.
4522 * Added silc_task_get_first function into lib/silcutil/silctask.c
4523 to return the timeout task with shortest timeout. There was a bug
4524 in task unregistration that caused problems. TODO has been
4525 updated to include that task system must be rewritten.
4527 * The client library will now resolve the client information when
4528 receiving JOIN notify from server for client that we know but
4529 have incomplete information.
4531 * Rewrote parts of silc_server_remove_from_channels and
4532 silc_server_remove_from_one_channel as they did not remove the
4533 channel in some circumstances even though they should've.
4535 * Encryption problem encountered in server:
4537 The LEAVE command used to send the Channel Key packet to the
4538 router immediately after generating it. However, the code
4539 had earlier sent Remove Channel user packet but not immediately,
4540 ie. it was put to queue. The order of packets in the router
4541 was that Channel Key packet was first and Remove Channel User
4542 packet was second, even though they were encrypted in the
4543 reverse order. For this reason, MAC check failed. Now, this
4544 is fixed by not sending the Channel Key packet immediately but
4545 putting it to queue. However, this is more fundamental problem:
4546 packets that are in queue should actually not be encrypted
4547 because packets that are sent immediately gets encrypted
4548 actually with wrong IV (and thus MAC check fails). So, packets
4549 that are in queue should be encrypted when they are sent to
4550 the wire and not when they put to the queue.
4552 However, the problem is that the current system has not been
4553 designed to work that way. Instead, the packet is encrypted
4554 as soon as possible and left to the queue. The queue is then
4555 just purged into wire. There won't be any fixes for this
4556 any time soon. So, the current semantic for packet sending
4559 o If you send packet to remote host and do not force the send
4560 (the packet will be in queue) then all subsequent packets to the
4561 same remote host must also be put to the queue. Only after the
4562 queue has been purged is it safe again to force the packet
4565 o If you send all packets immediately then it safe to send
4566 any of subsequent packets through the queue, however, after
4567 the first packet is put to queue then any subsequent packets
4568 must also be put to the queue.
4570 Follow these rules and everything works fine.
4572 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Added new function silc_server_remove_clients_by_server to
4575 remove all client entries from ID list when the server connection
4576 is lost. In this case it is also important to invalidate all
4577 client entires as they hold the invalid server entry. This
4578 fixes fatal bug when server has lost connection and will reconnect
4581 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Made some sanity checks to silc_server_daemonise like to check
4584 whether the requested user and group actually exists.
4586 * Added sanity check to SKE's silc_ske_responder_finish to check
4587 that the public and private key actually is valid.
4589 * Invalidate the client's nickname when receiving Replace ID
4590 packet and the Client ID is being replaced. This means that the
4591 server will query the nickname if someone needs it (client)
4594 * Sort the ID Cache in client library when the ID Cache data
4595 has changed (needs sorting).
4597 * Do not allow for SILC client to create several connections to
4598 several servers. The client does not support windows right now
4599 and generating multiple connections causes weird behaviour.
4601 Irssi-silc client does support windows and can handle several
4602 connections without problems, see: www.irssi.org and SILC plugin.
4604 * Fixed some places where client was added to the IDList. The
4605 rule of thumb is following (in order to get everything right):
4606 If the client is directly connected local client then the
4607 `connection' argument must be set and `router' argument must be
4608 NULL to silc_idlist_add_client function. If the client is not
4609 directly connected client then the `router' argument must
4610 bet set and the `connection' argument must be NULL to the
4611 silc_idlist_add_client function.
4613 * The funtion silc_server_packet_send_local_channel actually did
4614 not check whether the client was locally connected or not. It
4615 does that now. Fixed a bug related to LEAVE command.
4617 * Fixed Remove Channel User payload parsing bug in server's
4618 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4620 * The server's silc_server_save_channel_key now checks also the
4621 global ID list for the channel as it might not be in the local
4622 list. Fixed a bug related to LEAVE command.
4624 * Is this the end of the [<unknown>] buglet that has been lurking
4625 around for a long time? A little for loop fix in server's
4626 silc_server_command_whois_parse that is used by both IDENTIFY
4627 and WHOIS command. At least, this was a clear bug and a cause
4628 of one type of [<unknown>] buglet.
4630 * WHOIS and IDENTIFY commands call the function
4631 silc_server_command_[whois/identify]_check function even if
4632 we are not router server.
4634 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added --with-gmp configuration option. If set the GMP
4637 is always compiled in the SILC source tree. If not set then
4638 it is checked whether the system has the GMP3 installed. If
4639 it has then the GMP won't be compiled (the system's headers
4640 and library is used), if it doesn't have it then the GMP is
4641 compiled in the SILC source tree.
4643 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Changed RSA private exponent generation to what PKCS #1
4646 suggests. We try to find the smallest possible d by doing
4647 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4648 not security fix but optimization.
4650 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Added new config entry [Identity] to fork the server and run
4653 it as specific user and group. A patch from Bostik.
4655 * Imported Dotconf configuration library into lib/dotconf.
4656 This will be used to create the SILC configuration files later.
4657 It will appear in the distsribution after this commit.
4659 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * A big code auditing weekend happening. Auditing code for
4662 obvious mistakes, bugs and errors. Also, removing any code
4665 Removed files for being obsolete:
4667 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4668 inline in the file lib/silcutil/silcbuffer.h)
4670 o lib/silcutil/silcbufutil.c (the header has inline versions)
4672 Changed code to fix possible error conditions:
4674 o The buffer formatting routines now check that the destination
4675 buffer really has enough space to add the data. This applies for
4676 both buffer formatting and unformatting
4677 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4678 unformatting was changed to accomodate following rules:
4679 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4680 sent to the function while XXX_*STRING will not allocate or copy
4681 the data into the buffer. Instead it sets the pointer from the
4682 buffer into the pointer sent as argument (XXX_*STRING used to
4683 require that the pointer must be allocated already). This change
4684 makes this whole thing a bit more consistent and more optimized
4685 (note that the data returned in the unformatting with XXX_*STRING
4686 must not be freed now). The routines return now -1 on error.
4688 o Tried to find all code that use buffer_format and buffer_unformat
4689 and added return value checking to prevent formatting and
4690 especially unformatting errors and possible subsequent fatal
4693 o Changed ske->x and ske->KEY to mallocated pointers in
4694 lib/silcske/silcske.h. Fixed possible data and memory leak.
4696 o Added return value checking to all *_parse* functions. Fixed
4697 many memory leaks as well.
4699 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4700 so that buffer overflows would not happen. All code now also
4701 checks the return value as it can fail.
4703 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Added reconnection support to server if the normal server looses
4706 its connection to the router (for example if router is rebooted).
4707 The server performs normal reconnection strategy implemented
4708 to the server. Affected file silcd/server.c.
4710 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added new packet type SILC_PACKET_SET_MODE that is used to
4713 distribute the information about changed modes (for clients,
4714 channels and clients channel modes) to all routers in the
4715 network. Updated the protocol specification accordingly.
4717 Added functions into silcd/packet_send.c and
4718 silcd/packet_receive.c: silc_server_send_set_mode,
4719 silc_server_set_mode.
4721 Added new files silcmode.[ch] into lib/silccore that implements
4722 the encoding and decoding of Set Mode Payload. Added new type
4723 SilcSetModePayload. Moved the definitions of different modes
4724 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4726 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Oops, a little mistake in server's connection authentication
4729 protocol. The protocol is not ended with FAILURE but with
4730 SUCCESS if the authentication is Ok. :) Affected file is
4733 * Implemented NICK_CHANGE notify handling in server in the file
4734 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4735 the local clients on the channel. After the changing nickname
4736 in router environment snhould work and the [<unknown>] nickname
4737 should appear no more.
4739 The silc_server_replace_id function that receives the Replace ID
4740 payload now sends the NICK_CHANGE notify type also in the file
4741 silcd/packet_receive.c
4743 * Changed WHOIS and IDENTIFY command to support the maximum amount
4744 of arguments defined in protocol specs (3328 arguments). This
4745 fixed a bug that caused problems when there were more than three
4748 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Added extra parameter, command identifier, to the
4751 silc_client_send_command so that explicit command identifier
4754 Changed that ID list routines uses specific command identifier
4755 when sending WHOIS/IDENTIFY requests to the server so that they
4756 can be identified when the reply comes back.
4758 Affected files lib/silcclient/command.[ch],
4759 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4761 * Added `sender' argument to silc_server_packet_send_to_channel
4762 to indicaet the sender who originally sent the packet to us
4763 that we are now re-sending. Ignored if NULL. Affected file
4764 silcd/packet_send.[ch].
4766 * Added some server statistics support in silcd/server_internal.h
4767 SilcServerStatistics structure and around the server code. Also
4768 send some nice statistics information when client is connecting
4771 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Fixed channel ID decoding in server's JOIN command reply in
4774 silcd/command_reply.c
4776 * Fixed braodcasting of replace ID payload to not to send it if
4777 we are standalone server in silcd/packet_receive.c.
4779 * Fixed all channel message sending routines to not to send
4780 packets to clients that has router set, since they are routed
4781 separately in the same function earlier. Affects file
4782 silcd/packet_send.c and all channel packet sending functions.
4784 * In USERS reply, res_argv[i] are not allocated, the table
4785 is allocated. Thus changed that free the table, not its
4788 * In server's whois_check and identify_check if the client is
4789 locally connected do not send any WHOIS commands - they are not
4792 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Fixed some minor bugs in client when sending WHOIS command. The
4795 arguments was in wrong order.
4797 * Removed statis function add_to_channel from server in
4798 silcd/command.c that was previously used with the joining but
4801 * Tested USERS command in router environment successfully with two
4802 routers, two servers and two clients.
4804 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Reorganized the USERS command and command reply in client library
4807 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4808 When the command is given by user we register a pending command
4809 callback that will reprocess the command after the reply has been
4810 received from the server. When reprocessing the packet we then
4811 display the information. Thus, the USERS information is displayed
4812 now in the command callback instead of in the command reply
4813 callback. The processing of the command is same as previously
4814 when server has sent the command reply in the JOINing process.
4816 * Added to USERS command in silcd/command_reply.c to join the client,
4817 we didn't use to know about, to the channel after we've created
4818 a client entry for it. Also, for clienet we did know already still
4819 check whether it is on the channel or not and add it if not.
4821 * Removed silc_server_command_join_notify as the function and its
4824 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Changed the client's pending command handling to the same as the
4827 server's pending command handling. It is also now possible to
4828 execute command reply functions from other command reply
4829 function as the function callbacks for commands and command
4830 replies are one and same. The pending commands are not static
4831 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4832 in client connection context. Thus, pending commands are server
4833 connection specific as it is convenient.
4835 Changed the function silc_client_command_pending and
4836 silc_client_command_pending_del and added new function
4837 silc_client_command_pending_check. Removed the
4838 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4841 * Added cmd_ident, current command identifier, to the client
4842 connection context in lib/silcclient/client.h to keep track on
4843 command identifiers used in command sending. Client's command reply
4844 function handling now supports the mandatory command identifiers.
4846 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4847 funtions in client to fully support pending command callbacks.
4849 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4850 as one of the arguments to the application in the command reply
4853 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4854 before first releasing SILC but came back. Now it is removed again
4855 and should come back nomore. The FORWARDED flag was used only
4856 by the JOINing procedure by forwarding the command packet to router.
4857 Now, the JOINing procedure has been changed to more generic (due
4858 to various router environment issues) and FORWARDED is not needed
4859 anymore for anything. The protocol specification is yet to be
4862 Now, removed silc_server_packet_forward from server and the flag
4863 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4865 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Renamed NAMES command to USERS command. The NAMES was named that
4868 due to historical reasons. Now it is renamed. Also, rewrote
4869 parts of the USERS command. The nickname list is not sent anymore
4870 by the server. Only Client ID and mode lists are sent in the USERS
4871 command. Changed this also to the protocol specification.
4873 The client now resolves the names and stuff after it receives
4874 the USERS list from the server when joining to the channel.
4876 * WHOIS and IDENTIFY commands has been changed to support multiple
4877 Client ID's per command. One can now search for multiple users
4878 in the network by sending only one WHOIS or IDENTIFY command.
4879 Changed the code and the protocol specifications.
4881 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4882 uses silc_server_command_whois_parse to parse the request. */
4884 * If normal server, do not parse the WHOIS and IDENTIFY requests
4885 before sending it to the router. Saves some time.
4887 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Fixed JOIN command on client library. Wrong number of arguments
4890 used to crash the client.
4892 * Added silc_server_channel_has_global function to check whether
4893 channel has global users or not.
4895 * Added silc_server_channel_has_local function to check whether channel
4896 has locally connected clients on the channel.
4898 * The silc_server_remove_from_one_channel now checks whether the
4899 channel has global users or not after given client was removed from
4900 the channel. It also checks whether the channel has local clients
4901 on the channel anymore. If it does not have then the channel entry
4902 is removed as it is not needed anymore.
4904 * The silc_server_notify now checks on JOIN notify whether the joining
4905 client is one of locally connected or global. If it is global then
4906 the channel has now global users on the channel and that is marked
4907 to the channel entry. Also, it now saves the global client to
4908 global list who is joining and JOINs it to the channel. This is
4909 for normal server, that is.
4911 Changed silc_server_send_notify_on_channel,
4912 silc_server_packet_relay_to_channel and
4913 silc_server_packet_send_to_channel check if we are normal server
4914 and client has router set (ie. global client) do not send the
4915 message to that client, as it is already routed to our router.
4917 * Implemented LEAVE notify type handling in silc_server_notify
4920 * Tested LEAVE command in router environment successfully. Tested
4921 with two routers, two servers and two clients.
4925 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4927 * Implemented SIGNOFF notify type handling in silc_server_notify
4930 * silc_server_remove_id now removes the client entry from all channels
4931 it has joined and thusly sends SIGNOFF notify type.
4933 * Rewrote the NAMES list generation in server by removing two excess
4934 loops. The lists are created now inside one loop.
4936 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * silc_server_remove_channel_user checks now also global list
4939 for channel and client.
4941 * silc_server_new_channel_user checks now both local and global
4942 list for channel and client. Fixed a bug in client id decoding.
4943 Used to decode wrong buffer.
4945 * silc_server_channel_message checks now both local and global
4946 list for channel entry.
4948 * Tested channel joining (hence JOIN) in router environment
4949 successfully. Tested with two routers, two servers and two
4952 * Tested channel message sending in router environment successfully.
4954 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Added silc_server_save_channel_key into server.[ch] to save the
4957 received channel key in Channel Key payload processing. It is
4958 also used in JOIN command reply handling.
4960 Equivalent function silc_client_save_channel_key added into
4961 client.[ch] into client library.
4963 * Changed JOIN command reply to send information whether the channel
4964 was created or not (is existing already) and the channel key
4965 payload. Changed protocol specs accordingly.
4967 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4968 the request was sent by ID and not by nickname. Crashed on
4971 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4974 now correctly save the received data.
4976 * silc_server_free_sock_user_data now notifies routers in the
4977 network about entities leaving the network.
4979 At the same time implemented functions silc_server_remove_id
4980 and silc_server_send_remove_id to receive and send REMOVE_ID
4981 packets. The packet is used to notify routers in the network
4982 about leaving entities. The ID removed will become invalid in
4985 * Added function silc_idlist_del_server into server. Removes and
4986 free's server entry from ID list.
4988 * silc_server_private_message function now checks, if we are router,
4989 that the destination ID really is valid ID, naturally.
4991 * In router when NEW_ID packet is received (for new client) the
4992 hash of the Client ID is saved in the ID Cache but the
4993 client->nickname is set to NULL, instead of putting the hash
4996 IDENTIFY command now also checks that client->nickname must be
4997 valid. If it is not if will request the data from the server who
4998 owns the client. Added new function
4999 silc_server_command_identify_check.
5001 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5002 to set the command to already allocated Command Payload.
5004 * Tested private message sending in router environment with two
5005 routers, two servers and two clients. Fixed minor bugs and now
5008 * Fixed segfault from client's NAMES command. Used to crash if
5011 * Forwarded packets must not be routed even if it is not destined
5012 to the receiver. Changed server code comply with this.
5014 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Added `require_reverse_mapping' boolean value to ServerParams
5017 structure. If TRUE (not default) the server will require that
5018 the connecting host has fully qualified domain name.
5020 If the reverse mapping is not required and hostname could not be
5021 found the IP address is used as hostname.
5023 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Implemented version string checking to both client and server.
5026 The check is incomplete currently due to the abnormal version
5027 strings used in development version of SILC.
5029 * Changed all command functions in server to use the new
5032 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Changed char *data to unsigned char *data in ID Cache system to
5035 support binary data as ID Cache data. Changed code to support
5036 binary data in lib/silccore/idcache.c.
5038 * Renamed silc_server_packet_relay_command_reply to
5039 silc_server_command_reply as it is normal packet receiving
5040 function. Rewrote the function to accept command replys for
5041 servers and not only for clients.
5043 * Mark remote router always as registered server if we are connecting
5044 to it. Otherwise, commands sent by the router to us are ignored.
5046 * All ID List find routines now returns the ID Cache Entry pointer
5047 as well if requested.
5049 * WHOIS command works now in router environment, tested with two
5050 routers, two servers and two clients.
5052 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5053 in router environment (as it is almost equivalent to WHOIS) but
5054 hasn't been tested thoroughly. Added new functions:
5056 silc_server_command_identify_parse
5057 silc_server_command_identify_send_reply
5058 silc_server_command_identify_from_client
5059 silc_server_command_identify_from_server
5061 * Disabled route cache adding because adding two different ID's with
5062 same IP replaces the old cache entry thus giving wrong route.
5063 The entry->router->connection is always the fastest route anyway
5064 so route cache may not be needed. Of course, new routes maybe
5065 established after receiving the ID when the entry->router->connection
5066 might not be anymore the most optimal.
5068 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Add route cache for received ID for fast routing.
5072 * Added silc_server_packet_route to route received packet on router
5073 that is not destined to us.
5075 * Renamed silc_server_get_route to silc_server_route_get.
5077 * Added id_string and id_string_len fields into SilcServer to
5078 include encoded ServerID for fast comparing without excess
5079 encoding of the ID's.
5081 * Cleaned up WHOIS command on server side. Added following static
5084 silc_server_command_whois_parse
5085 silc_server_command_whois_check
5086 silc_server_command_whois_send_reply
5087 silc_server_command_whois_from_client
5088 silc_server_command_whois_from_server
5090 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5091 arguments in command replies. All command functions should be
5092 updated to use this macro.
5094 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Minor typo fixes on command reply handling on server.
5098 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Added silc_server_command_add_to_channel internal routine to add
5101 the client to the channel after router has created the channel and
5102 sent command reply to the server.
5104 * Added generic silc_server_send_command to send any command from
5107 * Use static buffer with ID rendering instead of duplicating data.
5109 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Fixed a channel user mode bug when joining to a channel server gave
5112 everybody channel founder rights, oops.
5114 * We mark ourselves as the router of the incoming server connection
5115 if we are router ourselves. This way we can check in some packet
5116 sending functions whether it is locally connected server. For
5117 incoming router connections we put NULL.
5119 * For router sending packets locally means now always sending the
5120 packet cell wide; to local clients and local servers. For normal
5121 server sending packet locally means sending it to only local
5124 * Fixed the JOIN command to really work in router environment. If the
5125 channel is created it is always created by the router. Router is
5126 also responsible of making the initial joining to the channel,
5127 sending JOIN notify to the sending server and distributing
5128 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5129 does not exist server doesn't do anything else but forward the
5130 command to the router which performs everything.
5132 * Added silc_server_send_channel_key function to send the Channel Key
5135 * Added silc_server_create_channel_key to create new channel key. The
5136 channel key is now re-generated everytime someone joins or leaves
5137 a channel, as protocol dictates. Note: channel->key_len is the
5140 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5143 packet_receive.[ch] to separate packet sending and receiving
5144 routines. The server.[ch] now includes everything else including
5145 actual packet processing (writing and reading data) and other
5148 Renamed silc_server_private_message_send_internal to
5149 silc_server_send_private_message. The routine is still though
5150 used only to relay private messages as server does not send
5151 private messages itself.
5153 Renamed silc_server_new_channel to silc_server_create_new_channel
5154 and added new function sicl_server_new_channel that handles the
5155 incoming New Channel packet. Added also new sending function
5156 silc_server_send_new_channel to send New Channel Payload.
5158 * Added new function silc_server_notify to process incoming notify
5159 packet to the server/router. Server may then relay the notify
5160 to clients if needed.
5162 * Added new function silc_server_new_channel_user to process incoming
5163 New Channel User packet. Router will redistribute the packet and
5164 send JOIN notify to its local clients and locally connected servers
5165 if needed. Normal server will send JOIN notify to its local client
5166 on same channel when received this packet. Added also corresponding
5167 sending function silc_server_send_new_channel_user to sent the
5170 * Added boolean route argument to send_notif_to_channel and
5171 packet_send_to_channel functions to attempt to route the packet
5172 if it is TRUE and send only locally if it is FALSE.
5174 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * silc_server_replace_id now broadcasts the received replace ID
5177 packet if it is not broadcast packet already. The router must
5178 broadcast to inform other routers about changed ID.
5180 * Added backpointer to server's router into SilcServer context in
5181 silcd/server_internal.h.
5183 * Fixed silc_server_packet_broadcast to send correct broadcast
5186 * The channel key is now distributed to the local client as soon
5187 as it is received from the router (in router environment) so that
5188 no other packet may be sent for the channel until client has
5191 * silc_server_remove_channel_user now broadcasts the received
5192 Remove Channel User packet if it is not broadcast packet already.
5193 The router must broadcast to inform other routers about removed
5196 * Added users field into SilcPacketContext that is a reference count
5197 of the context. One can increase the reference count by calling
5198 silc_packet_context_dup which is now changed to just increase the
5199 reference count instead of duplicating the data. The reference
5200 count is decresed by calling silc_packet_context_free that will
5201 free the data after the reference count hits zero.
5203 For now on the packet context and everything allocated into it
5204 (including the raw packet from network) must be freed by calling
5205 the new silc_packet_context_free function. Added also new function
5206 silc_packet_context_alloc that must be used now to allocate the
5207 context. This also means that if a routine is asynchronous from
5208 silc_[client/server]_packet_parse_type the packet context must
5209 be duplicated by calling silc_packet_context_dup. Otherwise it
5210 gets free'd after silc_[client/server]_packet_parse_type returns.
5211 Also, one must remember that if packet is duplicated then its
5212 reference count must be decresed by calling the free function as
5213 many times as it was duplicated.
5215 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5216 from both client and server.
5218 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Made joining to a channel working in router environment.
5222 * Cleaned up JOIN command on server side and create function
5223 silc_server_command_join_channel internal routine to make the
5226 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Changed silc_command_pending list to SilcDList. Also, added
5229 `ident' field to SilcServerCommandPending structure to identify
5230 the reply and to call correct callback.
5232 Added silc_server_command_pending_check function to replace the
5233 corresnponding macro. The silc_command_pending list is not
5236 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5237 to set identifier to previously allocated Command Payload. It
5238 is used to set identifier for command when resending Command
5241 * Added silc_command_payload_encode_payload to encode Command
5242 Payload buffer from SilcCommandPayload structure.
5244 * Added silc_argument_payload_encode_payload to encode Argument
5245 payload buffer from SilcArgumentPayload structure.
5247 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Changed WHOIS command to support router connection on server side.
5250 The whois request is always sent to router unless the server is
5251 standalone server. After server has received the reply from the
5252 router will it send the reply to the client.
5254 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5255 broadcast received broadcast packet. The function is used only
5256 by router. The broadcast packet is always sent to the router's
5259 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5260 render given ID to printable string, for log files for example.
5262 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Made basic router to router connections working. At least they
5265 can now connect to each other but nothing really works the way
5266 they are supposed - yet.
5268 * Added new initiator token to RouterConnection configuration
5269 file in silcd/serverconfig.[ch]. It is used to tell whether we
5270 are the initiator to the remote router or whether we'll expect
5271 the other end to connect.
5273 * Moved registering of listener task to silc_server_init, hence
5274 the server starts listenning as soon as it is run, even if it
5275 does not have connections to other routers. Let's see how well
5278 * Changed default connection retry timeouts for more suitable in
5281 * Removed cipher and such arguments from silc_idlist_add_client
5282 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5283 Added new function silc_idlist_add_data to add the keys and stuff
5286 * Added SilcIDListData structure and added it to SilcClientEntry
5287 and SilcServerEntry as their first field in the structure. This
5288 way we can explicitly cast the ID entries to the SilcIDListData
5289 structure and get common data for the entries. In past, we had
5290 to first check what type of connection it is and then cast it to
5291 correct ID entry type. Now, we can directly cast the opaque
5292 pointer to the SilcIDListData (no matter what ID entry it actually
5293 is) and get the data needed.
5295 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5298 in some circumstances even if threre were timeout tasks, though not
5299 IO tasks, but tasks anyway. Now fixed.
5301 * Defined SilcServerConnection structure to hold connection specific
5302 stuff about directly connected servers and routers. The definition
5303 is currently in silcd/server_internal.h. I thought about having
5304 a bit more important role fro this struct but for now it is used
5305 only when connecting to other server (or router actually).
5307 * Added connecting retry support in server when connecting to
5308 router(s). The retry feature implement exponential backoff
5309 algorithm. Also, added SilcServerParams structure to hold default
5310 parameters for server. For now, it include these retry settings
5311 and are hard coded. After server is moded to be as Silc Server
5312 Library this structure will be more important.
5314 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Changed client librarys channel->clients table to SilcList and
5317 changed code accordingly.
5319 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Changed client's channel table to SilcList and changed code
5322 accordingly. Also changed SilcChannelClientEntry to include back-
5323 pointer to the channel so that client entry can use that structure
5324 as list as well and we have fast cross-reference to the channel.
5325 This change dramatically decreased the complexity of channel
5326 handling with client entry and vice versa (removed one extra
5327 loop when searching for channel entry from many functions).
5329 * Changed server->sim from table to SilcDList and changed code
5332 * NAMES command can now be used from user interface. It will show
5333 the user list on the channel, neatly.
5335 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5336 Code now saves realname of the user if it becomes available.
5338 * Renamed configure.in to configure.in.pre and made ./prepare
5339 script to automatically add correct version string to
5340 configure.in which it creates from configure.in.pre.
5342 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * NAMES command reply now shows users mode with the nickname when
5347 * Moved silc_client_ch[u]mode[_char] functions from
5348 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5349 place sucks, they are utility functions and should be in some
5352 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5354 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5357 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Added TRQ (efficient deque and list library) into lib/trq. This is
5362 a very good list library that is currently used in the SILC. Defined
5363 SilcList API over the library because I didn't like the API very
5364 much. See lib/trq/silclist.h for the API and examples of how to
5365 use the API. Fixed various places in the code to use the new
5366 SilcList API. The SilcList is meant for lists that has a structure
5367 already defined as a list. It is not suitable to add just some
5368 context to the list (in TRQ, the context is the list actually).
5370 So, I defined SilcDList that can be used for the purpose where
5371 predefined list structure does not exit. This can be used as
5372 such list. Now some context just can be added to the SilcDList.
5373 Currently this list is not used in the SILC just yet, though there
5374 are a lot places where this can replace dynamically allocated
5375 tables and I will fix these places, later, to use SilcDList.
5376 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5377 and use TRQ internally).
5379 Also fixed some annoying warning messages that the original TRQ
5380 code generated. Also minor changes to TRQ's Makefile.in.
5382 * Added support for querying by Client ID to both WHOIS and
5383 IDENTIFY commands into server, as required by the protocol.
5385 * Removed method function pointers from SilcBuffer structure. They
5386 weren't used to anything and just increased the context size for
5387 no good reason. This change also made silc_buffer_alloc and
5388 silc_buffer_free functions inline functions.
5390 * Disabled command flooding detection support until it's fixed so
5391 that it accepts commands in but does not execute them more than once
5394 * Added silc_net_localhost(), to return local hostname, into
5395 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5396 that must be initialized before calling silc_client_init.
5398 * Added new function: silc_server_send_notify_on_channels to send
5399 notify messages to all channels client has joined. It is assured
5400 that the message is sent only once per client.
5402 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5403 lib/silcutil/silcutil.[ch] as silc_format function. The new
5404 function is generic and is used by server as well, not only by
5405 the logging routines.
5407 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5408 the provided version string was not acceptable. Added new function:
5409 silc_ske_check_version into lib/silcske/silcske.h. The function
5410 must be implemented by the application (client or server) and it
5411 does not reside in the SKE library. The function checks the version
5412 string remote end sent.
5414 * Added back pointers (to opaque context and to SilcSocketConnection)
5415 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5417 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5418 duplicate packet context structure.
5420 * Changed `notify' client operation to send same arguments as client
5421 receives from server except for ID's. ID's are mapped to correct
5422 ID entry and that is returned. Also, if channel entry is not sent
5423 by server but the notify is for channel the channel entry is sent
5424 to application (otherwise application doesn't know that it is for
5425 channel (library gets it from packet's Destination ID)).
5427 * Added silc_client_remove_from_channels into client library to
5428 remove a client from all channels it has joined to. Used when
5429 received SIGNOFF notify from server. Added also new function
5430 silc_client_replace_from_channels to replace old ID entry with
5431 new ID entry on all channels. Used when received NICK_CHANGE
5434 * Fixed ID Cache list handling in silc_idlist_get_client in
5435 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5436 to get (or query) client by ID.
5438 * Updated TODO list.
5440 * Added connection authentication status message defined by the
5441 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5442 support for these into the code in client and server side.
5444 * Added generic function silc_client_send_command to send any command
5445 with variable argument list. Application should use this function
5446 to send commands if the command functions provided by the library
5447 does not suite for the application's user interface needs.
5449 * Added new `failure' client operation. Application is notified about
5450 received failure packet if client is executing a protocol. In this
5451 case the protocol's execution has failed.
5453 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5454 is required by the protocol.
5456 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5457 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5460 * Added status flag to SilcSKE object to indicate realtime status
5461 of the SKE protocol.
5463 * Application receives now exactly same command reply arguments as
5464 the library receives from server. However, if ID is received the
5465 corresponding ID entry is returned to the application (eg. Client
5466 ID is mapped to correct SilcClientEntry entry and that is returned).
5467 Changed command_reply client operation due to this change.
5469 * Changed all ID's in commands and in command replys as ID Payloads.
5470 Change affected both client and server side codes.
5472 All ID's sent in SILC network (with execption of ID's in SILC
5473 Packet header) are sent in ID Payload to support variable length
5476 * Server now notifies nick changes and notifies all clients on
5477 the channels about the new nickname (about the new Client ID,
5480 * Implemented CMODE command to change channel modes. Supports all
5481 channel modes defined by the protocol specs except ban and invite
5482 lists. (Also, private channel key mode is supported but support for
5483 setting private channel key in client is missing, thus, this mode
5484 has no effect on client side (except that server requires that the
5485 client uses private channel key and normal channel traffic does not
5488 Also, invite mode works per se, but INVITE command does not work
5489 yet correctly, so you can set channel as invite only channel but
5490 inviting clients to the channel does not work (it is yet to be
5491 thought what's the best way to do it).
5493 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5494 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5495 Implemented CUMODE command to change user's mode on the channel.
5496 Supports all modes defined by the protocol specs.
5498 * Added NAMES command reply to return users modes on the channel.
5500 * Removed unnecessary and slow ciphers from lib/silccrypt.
5502 * Set SO_KEEPALIVE option to connection sockets by default.
5504 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5506 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5507 redefined the Notify Payload into protocol specs.
5509 * Added silc_id_payload_parse_id to get ID directly from raw
5512 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5515 accept searching by Client ID as well.
5517 * Added support for LEAVE and SIGNOFF notify types in client library.
5519 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5520 to parse ID Payload from raw data.
5522 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Added flags parameter into silc_ske_assemble_security_properties
5525 function in lib/silcske/silcske.[ch].
5527 * Changed notify client operation to fit better for notify messages
5528 sent by server. The notify payload received from server is now
5529 passed to the application (after parsing it to SilcNotifyPayload).
5530 It is application's responsibility to retrieve the arguments
5531 from the payload and show the message the way it wants. The message
5532 sent by server is implementation specific.
5534 * Changed public keys to comply with the protocol specification.
5535 Old public keys are not supported anymore and are not compatible.
5537 * Removed nickname from Channel Payload as the latest draft removed
5538 it. The client must resolve the nickname from the NAMES command
5539 reply received when it joined the channel.
5541 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5543 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Fixed some errors in protocol specification drafts.
5547 * Created lib/silccore/silcnotify.c to implement Notify Payload
5548 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5549 generic payloads described by protocol specifications. The file
5550 includes implementations for ID Payload and Argument Payload.
5552 * Changed Command Payload implementation to use the new Argument
5553 Payload. Changed command_xxxx_payload to command_payload_xxxx
5554 to comply with SILC coding conventions.
5556 * Added suppport for Argument Payload handling in Notify Payload
5557 implementation as protocol requires it. Added the new support
5558 into server and client lib as well.
5560 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5562 * Added support for multiple nicknames on same channel. [n] is
5563 added locally to the nickname if there are more than one same
5564 nicknames on the channel.
5566 * Server now sends all nicknames that matched WHOIS request.
5567 Client also shows the list received from server.
5569 * Added TOPIC command to client side. User can now set and show
5570 current topic on channel.
5572 * Added MOTD command to client and server. Also, server sends the
5573 motd when client connects to the server.
5575 * Changed version strings to comply ISO 8601.
5577 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Fixed protocol error handling in client library. It should now
5580 cope even if the SKE fails for some reason.
5582 * Made new protocol specification drafts for submitting to IETF.
5584 * Implemented TOPIC command to server in silcd/command.c.
5586 * Added two new notify types into lib/silccore/silcnotify.h:
5587 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5588 notify nickname change and topic setting/change on a channel.
5590 * API change of command_reply operation in client library. The
5591 application gets now the status type received from server as well.
5593 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5597 * Cras fixed and optimized the packet handling even further and
5598 it should work now. Minor change to the prototype of function
5599 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5601 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Added new function into lib/silcutil/silcschedule.[ch]:
5604 silc_schedule_with_fd to select() a specified fd. The function
5605 returns after timeout expires or data arrives or goes. The
5606 function is used by packet routines to wait that all data is
5607 received from network.
5609 * Fixed data reading from network in lib/silccore/silcpacket.c.
5610 The code now assures that all data is read from the fd and then
5611 continues packet processing. This was a bug fix since the code
5612 used to drop some data in some circumstances.
5614 * Added new function into lib/silcclient/client.[ch]:
5615 silc_client_start_key_exchange to start key exchange after
5616 connection has been established to server. The code internally
5617 now uses this funtion but its main purpose was to provide it
5618 for applications that perform their own connecting. After
5619 application has created a connection it merely calls this
5620 function to start the key exchange between client and server.
5621 The library takes care of everything else after that.
5623 Updated also lib/silcclient/README to explain the usage of
5626 * Do not send to application information that connection has
5627 been established. Application gets notified it by connect
5630 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Applied cras's patch to add silc_schedule_one function. The
5633 function runs scheduler once and returns.
5635 * Fixed the scheduler after cras messed it up. The timeout
5636 handling works now as it's supposed to work.
5638 * Added into lib/silccore/ silcnotify.h to include notify
5639 message types support. Changed silc_server_send_notify*
5640 functions, in server.[ch], to support those new notify types.
5641 Added the support for the notify types into client library,
5642 as well. Added new notify client operation into ops.h in
5645 * Changed silc_server_packet_send_to_channel to send normal
5646 packets instead of just channel message packets. The function
5647 is now used to send the notify packets to channels. It is not
5648 used to send channel message packets anymore, as server never
5651 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5652 va_arg()s as it seems to require it nowadays. I guess, if SILC
5653 is compiled with older va_arg() the new code should work anyway.
5655 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Splitted core library. Core library (lib/silccore) includes
5658 now only SILC protocol specific core (and common) components.
5659 Created new utility library (lib/silcutil) that includes more
5660 generic purpose stuff. The stuff for util library was taken
5661 from the old core library. This was minor and easy split.
5663 * Created SILC Client Library (lib/silcclient) that includes
5664 implementation of the SILC client without user interface. This
5665 was major move from silc/ directory. The code has been changed
5666 so that it is transparent towards the user interface. The
5667 silc/ directory includes now the same user interface as before
5668 and it uses the new client library. Read lib/silcclient/README.
5669 Basicly, the client library performs everything else related
5670 to SILC except user interface handling. Also, configuration
5671 files are considered to be part of user interface and library
5672 does not handle them.
5674 This change also changed a lot of structures, function naming etc.
5675 Most important change was that SilcClientWindow object was
5676 renamed to SilcClientConnection in the client library. Created
5677 also new file lib/silcclient/ops.h. Also added new files
5678 silc/local_command.[ch] and silc/client_ops.[ch].
5680 All these changes were made to make it easier for user interface
5681 designers to create what ever user interface for the SILC client
5684 It is also expected that the server will be moved to lib
5685 directory as well and SILC Server Library will be created;
5686 sometimes in the future.
5688 * Removed Local commands from lib/silccore/silccommand.h as
5689 they are application specific and new client library does not
5690 handle any of those anymore.
5692 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5693 old client implementation in silc/.
5695 * Added support for callback functions in SILC_LOG_* macros.
5696 Application can now set its own callbacks that will be called
5697 instead of using the default functions that will always print
5698 the debug messages to stderr (or stdout). Also, debugging can
5699 now be disabled by setting silc_debug to FALSE and re-enabled by
5700 setting it to TRUE. Note, that logging will still work even
5701 if debugging is disabled.
5703 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5704 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5705 silc_log_reset_debug_callbacks.
5707 * To enable debugging in silc client one must give now -d
5708 option on command line.
5710 * Changed silc_schedule_init to automatically allocate task queues
5711 if they are not allocated before calling it.
5713 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * Added GMP 3.1 into math library.
5717 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5720 a channel in SILC network. The packet is used by servers and
5721 routers to notify other routers that user has left a channel.
5722 This little feature was missing until now. Added the feature
5723 to protocol specification as well.
5725 Added functions: silc_server_send_remove_channel_user and
5726 silc_server_remove_channel_user into server.[ch].
5728 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5729 lib/silccore/silcpacket.h. However, they are not implemented
5732 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Fixed joining to a channel and sending channel messages
5735 between server and router. The channel message sending should
5736 now work inside a cell.
5738 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Fixed the private message sending between server and router.
5741 The private message sending should now work inside a cell.
5743 * Added silc_server_replace_id into server.[ch] to replace
5744 existing ID in the SILC network.
5746 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5747 and silc_idlist_replace_server_id into idlist.[ch] in server.
5749 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Fixed the server to server connections. Server can again now
5752 connect to router. Router to router connections probably does
5755 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added dynamic protocol registering support. Now protocols can
5758 registered and unregistered on the fly. Patch by cras.
5760 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Added lib/contrib directory to hold routines that some platforms
5763 don't have but are needed by SILC.
5765 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5766 into lin/contrib to provide getopt() and getopt_long() for
5767 those who don't have it.
5769 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added AWAY command to client. When away message is set and
5772 client receives a private message packet the client automatically
5773 replies to the sender with the away message.
5775 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5776 bug seemed to be the cause of recent problems when compiling
5779 * Added version detection support to SKE protocol specification
5780 and added the new changes to the SKE implementation as well.
5781 There were other minor changes in the SKE protocol as well.
5783 Many changes in lib/silcske/silcske.[ch] and in
5784 lib/silcske/payload.[ch].
5786 * Added ^U functionality, clear input line. Patch from cras.
5788 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Mainly small bugfixes on core library. Fixed some debugging
5791 logging and buffer overflow in silclog.c.
5793 * Updated config.sub and config.guess on the distribution tree.
5795 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Added command lagging support in server. Client may execute
5798 commands now only once in two seconds.
5800 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Optimized packet reception. MAC computation and checking is now
5803 also more optimized. A lot previously duplicated code is now
5804 used as generic by both client and server.
5806 * Fixed key pair generation in clientutil.c
5808 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Added into lib/silccore/silcbufutil.[ch] new function;
5811 silc_buffer_realloc.
5813 * Moved generic packet sending/encryption functions to
5814 lib/silccore/silcpacket.[ch] from client and server. Some
5815 rewriting of the functions.
5817 * Moved all generic packet reception/decryption functions to
5818 lib/silccore/silcpacket.[ch] from client and server. The
5819 packet processing is now much cleaner in both client and server.
5820 These were major changes in both client and server.
5822 * Created many common functions in server to do packet sending.
5823 Previously code were duplicated a lot, this has been removed
5826 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Rewrote major parts of the ID cache system. Don't know
5829 whether it is better now or not but at least the API is more
5832 * Major rewrite on ID cache stuff on client because of the ID
5833 cache API changes. Added idlist.c to client.
5835 * Also major rewrite on ID cache stuff on server as well.
5836 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5837 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5838 in hand, instead they are all put into the ID cache system now.
5839 All server_idlist_* routines uses ID cache now instead of
5840 traversing its own lists (those lists does not exist anymore).
5841 SilcIDList though still exists. Also, SilcXXXEntry's are
5844 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Finally made the SKE implementation compliant to the protocol
5847 specification. All mp integers are now binary encoded as
5848 opposed being HEX encoded.
5850 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5853 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5854 functions: silc_[encode/decode]_pem. Also added function
5855 silc_encode_pem_file to PEM encode with newlines ('\n') for
5858 * SILC public keys are now encoded either PEM or binary. Same
5859 option is for private keys as well. By default private keys
5860 are binary encoded and public keys PEM encoded. Silly HEX
5861 encoding were removed.
5863 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5864 function to create fingerprints.
5866 * Fixed a bug in SHA1; does not change the original data anymore.
5868 * Partly implemented INFO command on client and server side.
5869 Fixed CLEAR command. Changes to SERVER command; show current
5870 server(s) when giving command without arguments. Added
5871 VERSION command to client.
5873 * Added check to server that unregistered connections cannot
5874 execute commands (unless it is specificly allowed).
5876 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Fixed screen refresh.
5880 * Fixed channel joining bug from client. On some circumstances
5881 client tried to join to a channel it had already joined.
5883 * Added public key verification process into client's protocol.c.
5884 The client now verifies the public key from user and saves
5885 it into ~./silc/serverkeys/ directory.
5887 Added into: clientutil.[ch]: silc_client_verify_server_key.
5889 * Changed SKE protocol's silc_ske_initiator_finish function
5890 to accept callback function that verifies the received public
5891 key. Removed old silc_ske_verify_public_key function.
5893 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5896 silc_pkcs_private_key[_data]_set.
5898 * Made the password and public authentication more cleaner in
5899 server's protocol.c.
5901 * Removed historic and obsolete protocol `channel_auth' from
5902 both client and server.
5904 * Removed wrong way of sending command status messages from
5905 server to client in server's command.c. The old way violated
5906 protocol specification.
5908 Changes to silccore/silccommand.[ch]: removed
5909 silc_command_encode_status_payload -> not needed anymore,
5910 changed silc_command_encode_payload_va to accept extra
5911 argument on variable argument list. The argument type must
5912 now be provided to the function. Also, added new function:
5913 silc_command_encode_reply_payload_va which is same as
5914 normal command_encode_payload_va except command status type
5915 is provided as extra argument.
5917 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Added ~./silc directory handling. The directory includes the
5920 public and private keys for the client.
5922 Added silc_client_check_silc_dir, silc_client_create_identifier
5923 and silc_client_load_keys.
5925 * Implemented SILC protocol compliant public key. Added public
5926 and private key saving to and loading from files.
5928 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5929 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5930 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5931 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5932 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5934 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5935 silc_pkcs_load_[public/private]_key.
5937 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added silc_server_get_route (route.[ch]) to get connection
5940 data for the fastest route for given ID.
5942 * Implemented INVITE command on client and server. The command
5943 were re-defined in the SILC Protocol Specification and the
5944 implementation now complies with the specification.
5946 * Implemented PING command on client and server.
5948 * Implemented NAMES command on client and server. The server side
5949 supports currently only normal server not router server yet.
5950 Some changes to NAMES definition in SILC protocol specification.
5952 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Implemented LEAVE command on client and server.
5956 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5957 again. This change was made to the protocol as well. Server
5958 should not violate the protocol specification anymore.

5962 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5963 was tested. SOCKS4 was not but should work anyway.
