21 * Update the client entry context in the ID cache after
22 nick change. Affected file lib/silcclient/command.c.
23 Fixes the CUMODE command when regaining founder privileges,
24 and a little WHOIS problem.
26 * Fixed silc_net_gethostbyname to correctly call the
27 inet_ntop. Affected file lib/silcutil/silcnet.c.
29 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'

66 UI displays it. Affected files lib/silcclient/client_notify.c
67 and irssi/src/silc/core/silc-channels.c, module-formats.c.
69 * Made all payload parsing function prototypes consistent.
70 They all take now const unsigned char * and uint32 pair as
71 the payload data instead of SilcBuffer. Changes all around
72 the source tree. Other unsigned char* -> const unsigned char*
73 changes around the tree as well.
75 * Optimized SFTP client and server packet sending not to
76 allocate new buffer for each packet but to recycle the
77 first allocated buffer. Affected files are
78 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
80 * Optimized the SFTP client to use SilcList instead of
81 SilcDList for requests, because it is faster. Affected file
82 is lib/silcsftp/sftp_client.c.
84 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
85 into lib/silccore/silcid.[ch].
87 Renamed silcpayload.[ch] into silcargument.[ch].

91 * If client entry is deleted with active key agreement
92 session, abort the session.
94 The silc_client_abort_key_agreement now calls the completion
95 callback with new SILC_KEY_AGREEMENT_ABORTED status.
97 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
100 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Don't use __restrict in older GCC's. Affected file is
103 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
105 * silc_net_localhost now attempts to reverse lookup the
106 IP/hostname. Affected file lib/silcutil/silcnet.c.
108 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
109 command. It can be used to gain founder privileges at
110 the same time when joining the channel.
112 Defined that the SILC_NOTIFY_TYPE_KICKED send the
113 kicker's client ID as well. Updated protocol specs.
115 Defined that the server must send SILC_COMMAND_IDENTIFY
116 command reply with error status to client who sent
117 private message with invalid client ID.
119 Updated the protocol specification.
121 * Added silc_server_send_command_reply to send any
122 command reply. Affected file silcd/packet_send.[ch].
124 * Added silc_id_payload_encode_data to encode ID payload
125 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
127 * The server now send IDENTIFY command reply with error
128 status if client ID in private message is invalid. Affected
129 file silcd/packet_receive.c.
131 * Save the server key file with server's IP address in
132 the filename instead of hostname. The affected file is
133 irssi/src/silc/core/client_ops.c.
135 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
140 * Added libtool support for compiling shared objects in
141 lib/silcsim. Affected file configure.in.pre and
142 lib/silcsim/Makefile.am. Original patch by cras.
144 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
146 * Pid file configuration, and server's config file fixes
147 patch by toma. Updated CREDITS file.
149 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
151 * Fixed silc_client_channel_message to not try to decrypt
152 the message twice if it resolved the destination client
153 information. This could cause of dropping one channel
154 message. Affected file lib/silcclient/client_channel.c.
156 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
158 * Added silc_client_run_one into lib/silcclient/silcapi.h and
159 lib/silcclient/client.c. This function is used when the SILC
160 Client is run under some other scheduler, or event loop or
161 main loop. On GUI applications, for example this may be
162 desired to used to run the client under the GUI application's
163 main loop. Typically the GUI application would register an
164 idle task that calls this function multiple times in a second
165 to quickly process the SILC specific data.
167 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
169 * Fixed silc_server_drop() for dropping the supplementary
170 groups as well, this could cause a security hole on some
173 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
175 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

191 the dynamic list. Fixes a crash. Affected file is
192 lib/silccore/silcidcache.c.
194 * Fixed the LIST command reply to really call LIST command's
195 pending callbacks. Affected file silcd/command_reply.c.
197 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
199 * Update conn->local_entry->nickname after giving NICK
200 command. Affected file lib/silcclient/command.c.
202 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
204 * Added the [pid] option to the silcd configuration file
206 Affected files: serverconfig.[ch] and silcd.c

210 * Save fingerprint in WHOIS command reply in server.
211 Affected file silcd/command_reply.c.
213 * Fixed NICK commands pending callback registration.
214 Affected file lib/silcclient/command.c.
216 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
218 * Use ++server->cmd_ident when sending commands in server,
219 instead of random number. Affected file silcd/command.c.
221 * Fixed GETKEY command reply to call actually GETKEY pending
222 command callbacks. Affected file silcd/command_reply.c.
224 * A bit stricter check for nicknames. Check for same nickname
225 in NICK command also. Affected file silcd/command.c.
227 * Do not call INFO command everytime client ID changes, only
228 during first connecting. Affected file lib/silcclient/client.c.
230 * Set the new nickname only after successful command reply for
231 NICK command is returned by server. Affected file
232 lib/silcclient/command.c.
234 * Remove nicknames from nicklist during server_signoff notify.
235 Should fix /NAMES bit more. The affected file is
236 irssi/src/silc/core/silc-channels.c.
238 * Added `fingerprint' field to the SilcIDListData in the
239 silcd/idlist.h to hold the fingerprint of the client's
242 Send the fingerprint of the client's public key in WHOIS
245 Affected files silcd/command.c, and silcd/idlist.[ch].
247 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
248 create fingerprint from given data.
250 * Show the fingerprint of the client's public key in WHOIS.
251 Affected files irssi/src/module-formats.[ch] and
252 irssi/src/silc/core/client_ops.c.
254 * Format the multiple same nicknames also during JOIN and
255 NICK_CHANGE notifys. Affected file is
256 lib/silcclient/client_notify.c.
258 * Do not print error on screen for invalid private message
259 payload since it can come if someone is sending private
260 messages with wrong key. Affected file
261 lib/silccore/silcprivate.c.
263 * Fixed multiple concurrent /PING crash. Affected file
264 lib/silcclient/command.c.
266 * Changed the wrong ID encoding. All IP addresses must be
267 in MSB first order in encoded format. They were encoded
268 wrong and was in LSB format. Affected files are
269 silcd/serverid.c, lib/silcutil/silcutil.c.
271 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
273 * Call the `connect' client operation through the scheduler
274 in case of error. Affected file lib/silcclient/client.c.
276 * Call the `failure' client operation even if the error
277 occurred locally during a protocol. Affected file is
278 lib/silcclient/protocol.c.
280 * Added support of sending LIST command to router from normal
281 server. This way normal server can get list of all channels
282 in the network too. Fixed the channel list sending in the
283 server too. Affected files are silcd/command.c, and
284 silcd/command_reply.[ch].
286 * Added silc_server_update_channels_by_server and
287 silc_server_remove_channels_by_server. They are used during
288 disconnection of primary router and in backup router protocol.
289 Affected file silcd/server_util.[ch], silcd/server.c and
290 silcd/server_backup.c.
292 * Fixed channel adding to global list in IDENTIFY command
293 reply in server. Affected file silcd/command_reply.c.
295 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
297 * If the incoming packet type is REKEY or REKEY_DONE process
298 that packet always synchronously. Fixes yet another MAC
299 failed error on slow (dialup) connections. Affected file
300 lib/silcclient/client.c and silcd/server.c.
302 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
304 * Call check_version SKE callback for initiator too. Affected
305 file lib/silcske/silcske.c.
307 * Implemented fix for security hole found in the SKE that was
308 fixed in the specification few days back; the initiator's
309 public key is now added to the HASH value computation.
310 Added backwards support for the old way of doing it too, for
311 old clients and old servers. Affected file is
312 lib/silcske/silcske.c.
314 * Enabled mutual authentication by default in SKE. If initiator
315 is not providing mutual authentication the responder will
316 force it. This will provide the proof of posession of the
317 private key for responder. The affected files are
318 lib/silcclient/protocol.c and silcd/protocol.c.
320 * Do not cache anymore the server's public key during SKE.
321 We do mutual authentication so the proof of posession of
322 private key is done, and if the server is authenticated in
323 conn auth protocol with public key we must have the public
324 key already. Affected file silcd/protocol.c.
326 * Added new global debug variable: silc_debug_hexdump. If
327 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
328 file lib/silcutil/silclog.[ch].
330 * Fixed compilation warning due to char * -> const char *.
331 Affected files lib/silcutil/silcnet.h, and
332 lib/silccore/silcauth.[ch].
334 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
336 * Fixed CMODE command when new channel key was created. If
337 the creation failed the old key was removed. Next time giving
338 same command would crash the server since the old key was
339 freed already. Affected file silcd/command.c.
341 * Fixed the silc_server_announce_get_channels to not crash
342 on reconnect. Affected file silcd/server.c.
344 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
346 * Added silc_log_set_debug_string function to set a regex
347 string to match for debug output. Only the function names,
348 or filenames matching the given debug string is actually
349 printed. This way it is possible to filter out those debug
350 strings that user is not interested in.
352 Fixed a bug in silc_string_regexify.
354 Affected files lib/silcutil/silclog.[ch], and
355 lib/silcutil/unix/silcunixutil.c.
357 * Changed the -d options in both server and Irssi SILC client
358 to take the debug string as argument. Affected files
359 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
361 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
363 * Added silc_hash_babbleprint to create a Bubble Babble
364 Encoded fingerprint. The encoding is developed by Antti
365 Huima (draft-huima-babble-01.txt), and it creates human
366 readable strings out of binary data. Affected file
367 lib/silccrypt/silchash.[ch].
369 * Print the babble print now in addition of fingerprint as well
370 in Irssi SILC client. Affected files are
371 irssi/src/fe-common/silc/module-formats.[ch],
372 irssi/src/fe-common/silc/core/client_ops.c.
374 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
376 * Fixed a security problem found in SKE. The initiator's
377 public key too is now added to the HASH hash value creation
378 which is signed by the responder to create the SIGN value.
379 This will prevent anyone in the middle to lie to the responder
380 about the initiator's public key. If this is done now, the
381 man in the middle will get caught. Updated the protocol
384 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
386 * Better installation directory handling. Configure module
387 paths and other paths automatically to example_silc* files
388 in doc/. A patch by toma.
390 * Fixed compiler warning from MPI library, and from SILC RNG.
393 * Added SILC_SERVER_PID_FILE to define the pid file for server.
394 It can be configured with ./configure. A patch by toma.
396 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
398 * Find correct make to use in prepare-clean. A patch by
399 toma. Affected file prepare-clean.
401 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
403 * Added irssi variables use_auto_addr, auto_bind_ip,
404 auto_bind_port and auto_public_ip.
406 * Changed the interface for silc_client_send_key_agreement
407 in lib/silcclient/silcapi.h
411 irssi/src/silc/core/silc-core.c
413 lib/silcclient/silcapi.h
414 irssi/src/silc/core/silc-channels.c
415 lib/silcclient/client_keyagr.c
418 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
420 * Added silc_pkcs_public_key_compare to compare two
421 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
423 * Check that the client who set the founder mode on the
424 channel is the same client that is giving the founder
425 mode to itself. It is done by comparing the saved public
426 key (it is saved even in the authentication is passphrase).
427 Affected file silcd/command.c.
429 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Do not process packet for disconnected socket connection.
432 Affected file lib/silccore/silcpacket.c.
434 * Process the DISCONNECT packet through scheduler in the
435 client library. Affected file lib/silcclient/client.c.
437 * Fixed the silc_client_packet_parse to not to increase
438 the packet sequence number if the conn->sock and the
439 current socket connection is not same. This can happen
440 for example during key agreement when the conn includes
441 multiple socket connections (listeners). Affected file
442 lib/silcclient/client.c.
444 * The sender of the file transfer request now provides also
445 the pointer (listener) for the key exchange protocol. If
446 the listener cannot be created then it sends empty key
447 agreement and lets the receiver provide the listener.
449 Added `local_ip' and `local_port' arguments to the
450 silc_client_file_send. If they are provided they are used,
451 if not then it will attempt to find local IP address, if
452 not found or bind fails then the remote client will provide
455 Affected files are lib/silcclient/client_ftp.c and
456 lib/silcclient/silcapi.h.
458 * Extended the FILE SEND command to support defining the
459 local IP and port for key exchange listener. They are
460 optional. Affected file irssi/src/silc/core/silc-servers.c.
462 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
464 * Defined to WHOIS command reply the sending of fingerprint
465 of the client's public key (if the proof of posession of the
466 corresponding private key is verified by the server).
467 Updated to the protocol specification.
469 * Added support of receiving the client's public key's
470 fingerprint in command reply in client library. Affected
471 file is lib/silcclient/command_reply.c, and
472 lib/silcclient/idlist.[ch].
474 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Do not send over 128 chars long nickname to the server
477 in NICK command. Affected file lib/silcclient/command.c.
479 * Do not send over 256 chars long channel names to the server
480 in JOIN command. Affected file lib/silcclient/command.c.
482 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
484 * Assure that silc_server_close_connection cannot be called
485 twice for same socket context. Affected file is
488 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
490 * Send error message to application if opening file for
491 writing during file transfer fails. Affected file is
492 lib/silcclient/client_ftp.c.
494 Remove all file transfer sessions for a client that we're
495 removing from ID cache.
497 Affected file is lib/silcclient/client_ftp.c.
499 * Fixed silc_net_addr2bin to return correct address. Affected
500 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
502 * Fixed file transfer session removing on signoff notify.
503 Affected file irssi/src/silc/core/silc-servers.c.
505 * Added the SilcClientFileError to be returned in the monitor
506 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
507 Affected file lib/silcclient/silcapi.h.
509 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * Fixed a crash in silc_client_ftp_free_sessions and
512 silc_client_ftp_session_free_client. Affected file
513 lib/silcclient/client_ftp.c.
515 * Added `disabled' field in the SilcChannelEntry in the server
516 to indicate if the server entry is disabled. Affected file
517 silcd/idlist.h, silcd/command[_reply].c.
519 * SILC server adds now /var/run/silcd.pid everytime it is
520 started. Affected file silcd/silcd.c.
522 * Added silc_server_packet_send_clients to send a packet to
523 the provided table of client entries. Affected file
524 silcd/packet_send.[ch].
526 * Fixed a crash in client resolving in client_prvmsg.c in
527 client library. Affected file lib/silcclient/client_prvmsg.c.
529 * Do not actually remove the client directly from ID cache
530 during SERVER_SIGNOFF, but invalidate it. This way we
531 preserve the WHOWAS info for the client. Affected file
534 * Fixed SERVER_SIGNOFF notify handling in the server. The
535 server is now able to process incoming SERVER_SIGNOFF notify
536 for a server that it doesn't even know about. It will remove
537 the clients provided in the notify. Affected file
538 silcd/packet_receive.c.
540 * Check for partial packet in data queue after every packet that
541 was found from the queue. Return and wait for more data if
542 there is partial data in queue. Affected file is
543 lib/silccore/silcpacket.c.
545 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
547 * Added SilcClietFileError enum to indicate error in
548 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
549 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.

553 * Check that newsize in silc_buffer_realloc is larger than
554 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
556 * Added better monitor of file transfers. It now monitors
557 key agreement protocol during the file transfer too. Added
558 error reporting too. Affected files
559 irssi/src/silc/core/silc-servers.c,
560 irssi/src/fe-common/silc/module-formats.[ch].
562 * Wrote a help file for FILE command.
564 * Added silc_rng_global_get_byte_fast to get not-so-secure
565 random data as fast as possible. Random data is read from
566 /dev/urandom if available and from the SILC RNG if not
567 available. It is used in padding generation. Affected file
568 lib/silccrypt/silcrng.[ch].
570 * All packets in client library are now processed synchronously.
571 Optimized packet processing a lot. Affected file
572 lib/silcclient/client.c.

581 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
583 * Assure that silc_client_notify_by_server_resolve does not
584 resolve the client information multiple times. If it cannot
585 be found by the first it cannot be found at all. Affected
586 file lib/silcclient/client_notify.c.
588 * Fixed WHOWAS command reply calling. Affected file
589 lib/silcclient/command_reply.c.
591 * Removed all references to silc_idlist_get_client from the
592 Irssi SILC client since that call is internal call used by
593 the library. The Irssi SILC client will use now client
594 retrieval functions found in silcapi.h.
596 * Fixed a bug in resolving nickname info before sending
597 private message. It used freed memory. Affected file
598 irssi/src/silc/core/silc-servers.c.
600 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

620 Affected file lib/silcutil/silcnet.[ch].
622 * If key exchange or rekey protocol is active for a connection
623 parse all packets syncronously since there might be packets
624 in packet queue that we are not able to process without first
625 processing packets before them. Affected file silcd/server,
626 lib/silcclient/client.c.
628 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
629 whether library should continue processing the packet.
630 Affected file lib/silccore/silcpacket.h.

661 lib/silcutil/silcutil.[ch].
663 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Resolve the client info when received private message or
666 channel message for a client which nickname we don't know.
667 Affected files lib/silcclient/client_prvmsg.c and
668 lib/silcclient/client_channel.c.
670 * Do not crash in /KEY if client is not connected. Affected
671 file irssi/src/silc/core/silc-channels.c.
673 * Added SilcClientStatus field to the SilcClientEntry in the
674 lib/silcclient/idlist.h.
676 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
677 is incomplete and is being resolved, it won't be resolved
680 Make sure also that USERS command reply does not resolve
681 twice information. Affected file is
682 lib/silcclient/command_reply.c.
684 Make sure that silc_client_get_clients_by_list does not
685 resolve twice same information.
687 * Check for valid client->id in the silc_server_free_client_data.
688 Affected file silcd/server.c.
690 * Fixed /GETKEY nick@server not to crash if the server entry
691 is not found. Affected file lib/silcclient/command.c.

703 * Call the silc_server_udpate_servers_by_server in the
704 primary router that comes back online in the backup resuming
705 protocol. Otherwise it routes packets wrong. Affected file
706 silcd/server_util.[ch], silcd/server_backup.c.
708 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
711 lib/silcutil/silcbuffmt.[ch].
713 * Redefined the SILC packet header to include the padding
714 length. Affected file lib/silccore/silcpacket.[ch].
716 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
717 length for maximum padding up to 128 bytes). Affected
718 file lib/silccore/silcpacket.h.
720 * Removed all backwards support for old 0.5.x MAC thingies.
721 The SILC packet header change makes it impossible to be
722 backwards compatible.
724 * Send the ENDING packet with timeout in the backup resuming
725 protocol. This is to assure that all routers has connected
726 to the primary router. Affected file silcd/server_backup.c.
728 * Changed the RNG to take the first IV from random data. It
729 used to take it from zero actually. Changed the RNG also
730 to use /dev/urandom during session. /dev/random is used
731 in initialization. Affected file lib/silccrypt/silcrng.[ch].
733 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Changed the SILC packet header to have the first two bytes
736 (the packet length) encrypted. Affected files aroung the
737 code tree, lib/silccore/silcpacket.[ch]. Removed the
738 SilcPacketCheckDecrypt callback. It is not needed anymore
739 since the silc_packet_receive_process will determine now
740 whether the packet is normal or special.
742 * Implemented the unidirectional MAC keys. Affected files
743 lib/silcske/silcske.c, silcd/protocol.c and
744 lib/silcclient/protocol.c.
746 * Implemented the packet sequence number to the MAC computation.
747 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
748 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
749 lib/silcclient/protocol.c.
751 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Allow backup router to announce servers. All servers
754 announced by backup router are added to the global list
755 automatically. Update hte server's socket to our primary
756 router also when backup router announces a server.
757 Affected file silcd/packet_receive.c.
759 * Do not update the client->router in the function
760 silc_server_udpate_clients_by_server if the client is on
761 global list. We might fail to find any specific server
762 for locally connected clients and local cell clients. They
763 should still use the `from' and not `to' as client->router.
764 This fixes backup router resuming protocol. Affected file
767 * Decrease channel statistics count only if the channel
768 deletion worked. Affected files are silcd/server.c and
771 * Added silc_server_update_servers_by_server to update origin
772 of all server entries. Used during backup router protocol.
773 Affected files silcd/server_util.[ch], silcd/server.c. and
774 silcd/backup_router.c.
776 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
777 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
778 silc_hmac_get_hash and silc_hmac_get_name. Affected file
779 lib/silccrypt/silchmac.c.
781 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Assure that router cannot reroute the same channel message
784 to the sender. Affected file silcd/packet_receive.c.
786 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Made better checks that the channel message is not sent
789 to the router it came from. Affected file is
790 silcd/packet_send.c. Fixed memory leak too.
792 * Announce informations for incoming router connection, but
793 only after checking if it is replaced by backup router.
794 Affected file silcd/packet_receive.c.
796 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Fixed the backup resuming protocol to work in multiple
799 router environment. Affected file silcd/server_backup.c.
801 * Route packet only to one router in the function
802 silc_server_packet_send_to_channel. Affected file is
805 * Fixed silc_server_send_notify_dest to set the broadcast
806 flag. Fixed the silc_server_send_notify_topic to actually
807 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
808 Affected file silcd/packet_send.c.
810 * Changed the SFTP Filesystem interface. Changed the
811 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
812 the filesystem operation function. The SilcSFTPFilesystem
813 is now a context that is allocated by all filesystem allocation
814 functions and it already includes the operations structure
815 and filesystem specific context. It is given as argument
816 now to the silc_sftp_server_start. This made the interface
817 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
818 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
820 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
822 * Changed the backup router adding and getting interfaces
823 in the server. The router that will be replaced by the
824 specified backup router is now sent as argument. Affected
825 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
828 * Added silc_net_addr2bin_ne to return the binary form of
829 the IP address in network byte order. Affected files
830 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
832 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Check for existing server ID in silc_server_new_server
835 and in silc_server_connect_to_router_final and remove the
836 old entry if it exists. Affected file silcd/packet_receive.c,
839 * Send the channel message always to only one router, either
840 in upstream or downstream. Affected file is

846 protocol specification.
848 * Removed one redundant channel key generation from normal
849 server during joining procedure. Removed one redundant
850 channel key sending from server to router during joining
851 procedure. Affected file silcd/command.c.
853 * Made minor bugfixes to the backup router resuming protocol.
854 Affected file silcd/server_backup.c, server.c.
856 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

859 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
862 * Implemented the backup resuming protocol that is used to
863 resume the primary router position in the cell after the
864 primary router comes back online. Affected files
865 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
866 and silcd/server_util.[ch].
868 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

874 send any data. Affected file silcd/packet_send.c.
876 * Assure that if outgoing data buffer is pending do not force
877 send any data. Affected file lib/silcclient/client.c.
879 * Implemented the backup router support when the primary router
880 goes down. The servers and routers can now use the backup
881 router as new primary router without loosing connectivity.
883 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
886 in the server to indicate disabled entry. All data read
887 from the connection will be ignored and no data is sent
888 for entry that is disabled. Affected files are
889 silcd/idlist.h, silcd/server.c.
891 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Created SFTP client and server test programs in the
894 lib/silcsftp/tests directory.
896 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Implemented memory filesystem (virtual filesystem) for
899 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
902 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
904 * Implemented the SFTP (SSH File Transfer Protocol) to the
905 lib/silcsftp. It includes SFTP client and SFTP server
908 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Moved lib/silccore/silcprotocol.[ch] to the
911 lib/silcutil library.
913 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
914 take variable argument list pointer as argument. Affected
915 file lib/silcutil/silcbuffmt.[ch].
917 * Added silc_buffer_set function that is used to set data
918 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
919 Affected file lib/silcutil/silcbuffer.h.
921 * Changed various routines in the core library to use the new
922 silc_buffer_set instead of allocating new buffer only for
925 * Added 64-bit value formatting and unformatting support to the
926 silc_buffer_[un]format routines. Affected file is
927 lib/silcutil/silcbuffmt.[ch].
929 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
930 to includes/bitmove.h.
932 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Fixed channel user mode saving in client library. Affected
935 file lib/silcclient/command[_reply].c.
937 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Defined the file transfer to the SILC Protocol. Added
940 new packet type SILC_PACKET_FTP and defined File Transfer
941 Payload. The mandatory file transfer protocol is SFTP
942 (SSH File Transfer Protocol). Affected file in addition
943 of the internet draft is lib/silccore/silcpacket.h.
945 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
946 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
947 is used as part of backup router protocol when the primary
948 router of the cell is back online and wishes to resume
949 the position as primary router.
951 * Redefined the MAC generation keys in the protocol. The
952 same key is not used anymore in both direction. Both
953 direction will now use different keys for sending and
954 receiving. This fixes a potential security flaw. This
955 change causes incompatibilities in the protocol.
957 * Redefined also the MAC computation from the packet.
958 An packet sequence number is now added to the MAC
959 computation. This prevents possible replay attacks against
960 the protocol. This change too causes incompatibilities
963 Added `sequence' field to the SilcPacketContext to hold
964 the current sequence number for the packet.
966 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Added `created' field to the SilcIDListData in the file
969 silcd/idlist.h to indicate the time when the entry was
972 * Added `created' field to the SilcChannelEntry too. Affected
975 * Added `creation_time' aguments to all the announcement functions
976 in the server. If it is provided then only the entries that
977 was created after the provided time frame are actually
978 announced. Affected file silcd/server.[ch].
980 * The protocol says that the Channel ID's IP address must be
981 based on the router's IP address. Added check for this in
982 the silc_server_new_channel when processing incoming New Channel
983 Payload. Affected file silcd/packet_receive.c.
985 * Print out the correct version with --version in SILC client.
986 Affected file irssi/src/silc/core/silc-core.c.
988 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

991 entry always, not just when the command is coming from client.
992 Affected file silcd/command.c.
994 * Added new function silc_server_packet_queue_purge to purge the
995 outgoing data queue to the network. After the function returns
996 it is guaranteed that the outgoing packet queue is empty.
997 Affected file silcd/packet_send.[ch].
999 * Purge the outgoing packet queue in the rekey protocol's final
1000 callback to assure that all rekey packets go to the network
1001 before quitting the protocol. Affected file silcd/server.c.
1003 * Added silc_client_packet_queue_parse as similar function as
1004 in server to the client library. The affected file is
1005 lib/silcclient/client.c.
1007 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Splitted silcd/server.c and created silcd/server_util.[ch]
1010 for utility functions.
1012 * Added new socket flag SILC_SF_DISABLED to indicate that the
1013 connection is open but nothing can be sent to or received from
1014 the connection. Affected file lib/silcutil/silsockconn.[ch].
1015 The checking for disabled socket is checked in the low level
1016 silc_socket_write and silc_socket_read functions.
1018 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * Allow only nicknames and channel names that fits into the
1021 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1023 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * When processing JOIN command reply in server check that if
1026 the channel exists in our global list we'll move it the local
1027 list. Affected file silcd/command_reply.c.
1029 * Fixed the check whether client is joined on the channel already
1030 in JOIN command. Affected file lib/silcclient/command.c.
1032 * Fixed the JOIN command reply to check whether the channel
1033 already exists. Affected file lib/silcclient/command_reply.c.
1035 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Added silc_ske_status_string to map the SKE error numbers
1038 to readable strings. The affected files are
1039 lib/silcske/silcske[_status].[ch].
1041 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * Do not show the private channels on the WHOIS channel list
1044 as it is not allowed by the protocol. The affected file is
1047 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1049 * Assure that the packet length digged from the actual packet
1050 is something sensible in the silc_packet_decrypt_rest_special
1051 in lib/silccrypt/silcpacket.c.
1053 * Free and NULL the allocated pointer in silc_hmac_alloc if
1054 the HMAC allocation fails. The affected file is
1055 lib/silccrypt/silchmac.c.
1057 * Print the selected security properties to the log files in
1058 the server. Affected file silcd/protocol.c.
1060 * Add SKE's reference counter even if calling the completion
1061 callback manually. Otherwise it goes negative, although it
1062 does not cause any problems. The affected file is
1063 lib/silcske/silcske.c.
1065 * Remove the client entry with short timeout after giving the
1066 KILL command. Affected file lib/silcclient/command.c.
1068 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1069 case all found clients are already disconnected (WHOWAS would
1070 found them) in the server. Affected file silcd/command.c.
1072 * Update the last_receive (time of last data received) to be
1073 updated only when received private or channel message so that
1074 the idle time showed in WHOIS makes more sense.
1076 * Added boolean field `valid' in to the SilcClientEntry in the
1077 client library to indicate whether the entry is valid or not.
1078 This fixes the nickname change bug on channel when changing
1079 the nickname to be same than the old (like nick to Nick) the
1080 nickname formatter doesn't set the new nick anymore to Nick@host.
1081 Affected file lib/silcclient/idlist.[ch].
1083 * Now actually fixed the nickname changing on disconnection.
1084 Added new function silc_change_nick to the Irssi SILC Client.
1085 Affected file irssi/src/silc/core/client_ops.c,
1086 irssi/src/silc/core/silc-nicklist.[ch].
1088 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1090 * Check that the public key exists in the GETKEY command before
1091 trying to encode it. Affected file silcd/command.c.
1093 * Print some notifications on received public keys with GETKEY
1094 command in the Irssi SILC Client. Affected files are
1095 irssi/src/fe-common/silc/module-formats.[ch],
1096 irssi/src/silc/core/client_ops.c.
1098 * Use IDENTIFY command to resolve the server information in the
1099 GETKEY command instead of INFO command. Affected file
1100 lib/silcclient/command.c.
1102 * All command reply functions in the client library now calls
1103 the pending command reply callbacks even if an error has
1104 occurred. The server has done this a long time and now it was
1105 time to move the client library to this as well. Now all
1106 errors can be delivered back to the pending command reply
1107 callbacks if necessary. Affected files are
1108 lib/silcclient/command[_reply].[ch].
1110 * Change the nickname on disconnection back to the username
1111 because in reconnect the server will enforce it to it anyway.
1112 Affected file irssi/src/silc/core/silc-servers.c.
1114 * Fixed a config file parsing bug in the Irssi SILC client.
1115 Affected file irssi/src/silc/core/clientconfig.c.
1117 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * When printing the channel mode on JOIN, verify that the
1120 channel key and channel's HMAC are valid. Affected file
1121 irssi/src/silc/core/client_ops.c.
1123 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1126 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1127 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1129 * Removed channel key rekey task deleting from the function
1130 silc_server_save_channel_key. Affected file silcd/server.c.
1131 Added explicit timeout task context instead that is used to
1132 delete the task if we are registering a new task before the
1133 new task has elapsed.
1135 * When channel key rekey occurs the client library now saves
1136 the old channel key for a short period of time (10 seconds) and
1137 is able to use it in case some is still sending channel
1138 messages encrypted with the old key after the rekey. Affected
1139 file lib/silcclient/[idlist.h|client_channel.c].
1141 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Added check to the silc_server_new_id_real to not accept
1144 new ID if it is the sender's own ID. Affected file is
1145 silcd/packet_receive.c.
1147 * Assure that we do not announce ourself or the one we've
1148 sending our announcements when we're router and are announcing
1149 servers to our primary router. Affected file silcd/server.c.
1151 * Fixed silc_server_command_identify_check_client to assemble
1152 correct WHOIS packet. It send corrupted WHOIS packet and
1153 caused problem with router to router connections. Affected
1154 file silcd/command.c.
1156 Fixed also silc_server_command_whois_check the same way
1157 as for the IDENTIFY command.
1159 * Added new SilcIDListStatus to the server in the SilcIDListData
1160 structure. The status now includes the current status of
1161 the entry (like registered, resolved etc.). Affected file
1162 silcd/idlist.[ch]. Defined a bunch of different status types
1163 as well. This replaced the old boolean registered field as well.
1165 Added resolve_cmd_ident field to the SilcClientEntry structure
1166 too so that if the entry is for example being resolved so
1167 another command may attach to the same pending command reply
1168 without requiring to resolve the same entry again. This concept
1169 should optimize the WHOIS and the IDENTIFY resolving under
1170 heavy load by taking away unnecessary resolving for entries
1171 that are being resolved already.
1173 Added support for adding multiple pending commands for one
1174 command idenfier. Affected file silcd/command[_reply].[ch].
1176 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1177 before deleting the data. Otherwise the hash table will have
1178 freed data in comparison functions. Affected file is
1179 silcd/command_reply.c.
1181 * Fixed silc_idlist_replace_client_id to add the new entry to
1182 the cache with NULL nickname. Otherwise there will be invalid
1183 memory as the nickname after the nickname is freed. Affected
1184 file silcd/packet_receive.c.
1186 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1187 saved into wrong slots because the previous number of entries
1188 was not taken into account. Affected file silcd/idlist.c.
1189 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1191 * If we are router and we receive JOIN notify to a channel that
1192 does not have any users then notified client is marked as the
1193 channel founder, as it is it. The affected file is
1194 silcd/packet_receive.c
1196 * Added to the extended hash table API's table_del_*ext functions
1197 the destructor as argument too, so that the caller can decide
1198 which destructor to use or whether to use destructor at all.
1199 Affected file lib/silcutil/silchashtable.[ch].
1201 * Fixed ID Cache purging. It actually deleted the entries from
1202 the hash table after the data was freed. The hash table ended
1203 up comparing freed memory. The affected file is
1204 lib/silccore/silcidcache.c.
1206 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Fixed Irssi SILC client's KILL command's HELP syntax.
1210 * The USERS command now resolves the detailed user information
1211 if the userinfo field is missing. Affected file is
1212 lib/silcclient/command_reply.c.
1214 * Do not print error in silc_file_read if the read file does
1215 not exist. Just silently return NULL. Affected file is
1216 lib/silcutil/silcutil.c.
1218 * Fixed the silc_log_output to not wine about NULL filename
1219 and to not create some bogus " " filename. Affected file is
1220 lib/silcutil/silclog.c.
1222 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Fixed various printing bugs on the user interface in the
1225 Irssi SILC Client. Minor changes that were forgotten from
1228 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Fixed the configure.in.pre and the compilation and distribution
1231 environment to support the new autoconf 2.52. That version is
1232 now required to compile the CVS trunk.
1234 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1236 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1237 to generally parse user@fqdn format strings. Affected file
1238 lib/silcutil/silcutil.c.
1240 * Added nickname_format and nickname_force_format fields to the
1241 SilcClientParams structure. The first one defines the format
1242 for the nicknames that the library will enforce if the receives
1243 multiple same nicknames. The second one is boolean value and
1244 can be used to force the library to always enforce the format
1245 to the nicknames regardles whether there are multiple nicknames
1246 or not. This configurable formatting was employed to flexibly
1247 support accessing multiple nicknames from the user interface.
1248 The userinterface can now set the nicknames to what ever format
1249 they prefer. Affected file lib/silcclient/silcapi.h.
1251 Added function silc_client_nickname_format to the file
1252 lib/silcclient/idlist.c. It performs the nickname formatting.
1254 Added new field `hostname´ to the SilcClientEntry context.
1255 It holds the hostname of the client. Affected file is
1256 lib/silcclient/idlist.h.
1258 * Irssi SILC Client sets the nicknames in nick@hostn format.
1259 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1260 irssi/src/silc/core/silc-core.c.
1262 The WHOIS printing now also shows both the real nickname and
1263 the formatted nickname so that user knows how to access the
1264 user if there are multiple same nicknames cached. Affected
1265 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1266 printing formatting too to take the hostname now as a separate
1267 argument. The Affected file is
1268 irssi/src/fe-common/silc/modules-formats.[ch].
1270 * Changed the silc_client_get_clients_local to accept the formatted
1271 nickname as argument. It accepts the real nickname too but the
1272 formatted nickname can be used to find the true entry from
1273 multiple entries. Affected file lib/silcclient/silcapi.h and
1274 lib/silcclient/idlist.c.
1276 * Added nickname_format_parse field to the SilcClientParams.
1277 It is a callback function provided by the application to parse
1278 the nickname out of the formatted nickname string. The library
1279 calls it to get the nickname from the formatted string. Since
1280 the application generally knows better the format of the nickname
1281 string it parses it instead of the library, even though library
1282 encodes the formatted string. If the callback function is not
1283 provided then the library will use the string as is. The
1284 affected file is lib/silcclient/silcapi.h.
1286 * All the nickname strings passed to the client library in
1287 commands are now expected to be formatted nickname strings.
1288 If the command does not support the formatted nickname string
1289 it will assume that the sent string is the actual nickname.
1290 Affected file lib/silcclient/command.c.
1292 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Added public key authentication support to OPER and SILCOPER
1295 commands in the client library. Affected file is
1296 lib/silcclient/command.c.
1298 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Changed the get_auth_methdod client operation to be asynchronous.
1301 It can be async if the application resolves the authentication
1302 method from the server during the negotiation. Added new
1303 SilcGetAuthMeth completion callback that the application will
1304 call after resolving the authentication method.
1306 Added function silc_client_request_authentication_method that
1307 the application can use to resolve the authentication method
1308 from the server. Added also SilcConnectionAuthRequest callback
1309 that the library will call after the server has replied. The
1310 application can call this function if it does not know the
1311 current authentication method.
1313 Affected files are lib/silcclient/client.c and
1314 lib/silcclient/silcapi.h.
1316 * The Irssi SILC client now automatically resolves the authentication
1317 method incase any configuration information is not present (and
1318 currently there never is). The affected file is
1319 irssi/src/silc/core/client_ops.c.
1321 * Fixed public key authentication from the client library.
1322 Affected file lib/silcclient/protocol.c. Changed also the
1323 protocol specification about the public key authentication in
1324 the connection authentication protocol. The actual data to be
1325 signed is now computed with a hash function before signing.
1327 * Fixed the public key authentication from the server as well.
1328 Affected file silcd/protocol.c.
1330 * Removed the mlock()'s from the memory allocation routines.
1331 Affected file lib/silcutil/silcmemory.c. The ./configure does
1332 not check anymore for the mlock(). Affected file is
1335 * Fixed USERS command in server to allow the execution of the
1336 command for private and secret channels if the client sending
1337 the command is on the channel. Affected file silcd/command.c.
1339 * Fixed silc_client_get_clients_local to return the clients
1340 count correctly. It could return wrong value. Affected file
1341 lib/silcclient/idlist.c.
1343 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1346 types. The assembler optimizations seemed not to like 64-bit
1347 data types. The assmebler optimizations thus are now enabled
1348 also for BSD systems as opposed to only enable them for Linux.
1350 * Do not check for threads at all on BSD systems. Affected
1351 file configure.in.pre.
1353 * Removed -n and -h options from the Irssi SILC Client since
1354 they are not used in silc.
1356 * Fixed the prime generation to assure that the first digit
1357 of the generated random number is not zero since our conversion
1358 routines does not like number strings that starts with zero
1359 digit. If zero digit is seen the random number is regenerated.
1360 This caused some corrupted RSA keys when the zero first digit
1361 was met. Affected file lib/silcmath/silcprimegen.c.
1363 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * Fixed WIN32 configuration in the ./configure script.
1366 Fixed to include xti.h on environments that has it.
1367 Patches by Carsten Ilchmann and andrew.
1369 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Changed the silc_id_create_client_id to be collision
1372 resistant. It is now assured that there cannot be created
1373 two same client ID's. I suspect that some weird bugs in
1374 the server were actually caused by duplicate Client IDs.
1375 Affected file silcd/serverid.[ch]. A router receiving
1376 new ID now also assures and informs the sending server
1377 if the ID caused collision.
1379 * Changed the silc_id_create_channel_id to also assure that
1380 there are no collisions.
1382 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Statement about ignoring the Mutual Authentication flag when
1385 performing rekey with PFS was a bit misleading. It is ignored
1386 if it was set in the initial negotiation, it cannot be even
1387 set in the rekey. Fixed in the ke-auth draft. Started the
1388 new versions of the protocol drafts in the doc/.
1390 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Fixed a bug in silc_client_command_identify_save when saving
1393 new channel information. The channel name was no duplicated
1394 and caused crash on exit. Affected file is
1395 lib/silcclient/command_reply.c.
1397 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Fixed the getkey command handling in the server. Send just
1400 empty OK reply to the sender if the key could not be fetched
1401 (but everything else was ok, like the key just was not available).
1402 Changed the public key parameter to optional in the protocol
1403 specs so that empty OK reply can be sent. Affected file
1406 Added a message to Irssi SILC client to tell to user if the
1407 server did not return a public key.
1409 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Fixed a channel key regeneration bug. It registered new
1412 timeout tasks exponentially until all system resources were
1413 used. Affected file silcd/server.c.
1415 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Added the SILC Document generator to the scripts/silcdoc.
1418 It can be used to generate the Toolkit Reference Manual out
1419 of the source tree. Internally it will also use the RoboDoc
1420 generator now imported in util/robodoc.
1422 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * Added couple of return's in rekey protocol if error orccurred
1425 during the protocol. The execution must be terminated.
1426 Affected file silcd/protocol.c. Also, terminate the protocol
1427 always with timeout.
1429 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * The client's Client ID was created initally from the wrong
1432 nickname (it could have been in format nick@host) in the
1433 silc_server_new_client. Affected file silcd/packet_receive.c
1435 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Added some SILC_LOG_ERROR's to various error conditions
1438 if client could not be added to ID cache. Affected files
1439 silcd/packet_receive.c and silcd/server.c.
1441 * When client's sock->user_data is freed, NULL also the
1442 client->router and client->connection pointers. Added check
1443 for these pointers being NULL to various places around the
1444 code. Affected file silcd/server.c.
1446 * Added client->data.registered == TRUE checks to various
1447 places around the code to assure that unregistered client's
1448 are not handled when it is not allowed. Affected file
1451 * Added `bool registered' fields to all
1452 silc_idlist_[server|client]_get_* routines to indicate whether
1453 the fetched client needs to be registered or not. Affected
1454 file silcd/idlist.[ch].
1456 * Add your own entry as registered to the ID cache in the
1457 server. Affected file server.c.
1459 * Fixed a bug in silc_server_new_server. The SilcServer was
1460 set as the new server's context instead of SilcServerEntry.
1461 This naturally caused some weird bugs.
1463 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Do not delete the channel rekey task when adding it
1466 for in silc_server_create_channel_key.
1468 * Changed the silc_server_create_channel_key to return
1469 TRUE or FALSE to indicate the success of the channel key
1472 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Fixed MSVC++ project files and added missing files to
1475 Makefiles under win32/.
1477 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Do not add TCP_NODELAY flag if the operating system
1480 does not have it defined. Affected files are
1481 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1483 * Fixed buffer overflow from Irssi SILC Client. Affected
1484 file irssi/src/fe-common/core/themes.c.
1486 * Fixed double free in client library in the file
1487 lib/silcclient/client.c when disconnecting from server.
1489 * Applied double free patch from cras to Irssi SILC client.
1490 Affected files irssi/src/core/[modules/expandos].c
1492 * Fixed the disconnection handling to Irssi SILC Client.
1493 The application must call silc_client_close_connection
1494 in ops->connect client operation in case of failure of
1495 the connection. Affected file is
1496 irssi/src/silc/core/client_ops.c.
1498 * Do not set sock->protocol to NULL in the function
1499 silc_client_close_connection after executing the protocol's
1500 final callback since the sock might not be valid anymore.
1501 Affected file lib/silcclient/client.c.
1503 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Do not enable SILC_THREADS if the linking with libpthread
1506 did not happen. Affected file configure.in.pre.
1508 * Added notion to protocol specification that server must
1509 verify the sent authentication payload with CMODE when
1510 setting the channel founder key. Implemented it to the
1511 server. Affected file silcd/command.c.
1513 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Added _EXTRA_DIST SILC distribution variable to the
1516 distributions file. It is used to conditionally add extra
1517 files or directories to the specific distribution. Affected
1518 files ./prepare, Makefile.am.pre and distributions.
1520 Removed the `_' from the start of the distribution names.
1523 * Added README.WIN32 for instructions to compile the Toolkit
1526 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Fixed a double free in disconnection in the server. Affected
1529 file is silcd/server.c.
1531 * Fixed the lib/silcske/groups.c to work now also with GMP
1532 MP library. The string conversion did not work when using
1533 specific base and the base is indicated in the string as well.
1535 * Created win32/ directory which now includes MSVC++ specific
1536 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1537 It will appear only in the toolkit distribution
1539 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Changed the key material distribution function in case when
1542 the hash output is too short. The data is now concatenated
1543 a bit differently than it used to. Made the change to the
1544 SKE protocol specification.
1546 * Added better GMP detection to configure.in.pre. A patch
1549 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Fixed a minor bug in SKE that might cause some problem on
1552 some platforms. Affected file lib/silcske/silcske.c.
1554 * Added the cookie checking for initiator in the SKE. It checks
1555 that the responder returns the sent cookie unmodified. The
1556 affected file is lib/silcske/silcske.c. Added new SKE
1557 error type INVALID_COOKIE that can be sent during the
1558 negotiation. Fixed some memory leaks as well.
1560 * Added the "invalid cookie" error message to Irssi SILC client's
1563 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Added `task_max' field to the SilcClientParams to indicate
1566 the maximum tasks the scheduler can handle. If set to zero,
1567 default values are used. Affected file lib/silcclient/silcapi.h.
1569 * Fixed memory leaks in silc_client_close_connection. Affected
1570 file lib/silcclient/client.c.
1572 * Added silc_client_del_client_entry to client library to free
1573 all memory of given client entry. Affected file is
1574 lib/silcclient/idlist.[ch].
1576 * Added new functions silc_client_del_channel and
1577 silc_client_del_server to delete channel and server entries.
1578 Affected file lib/silcclient/[silcapi.h/idlist.c].
1580 * Removed silc_client_del_client_by_id from silcapi.h.
1582 * Fixed the INFO command to return the server's own info
1583 correctly when querying by Server ID. Affected file is
1586 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Removed the non-blocking settings in WIN32 code in the
1589 silc_sock_[read/write] and added SleepEx instead. Affected
1590 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1591 of input data is now checked with FIONREAD and ioctlsocket.
1593 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Call silc_schedule_task_del_by_context in the
1596 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1597 Affected file lib/silccore/silcprotocol.c.
1599 * Call silc_protocol_cancel for active protocols in the
1600 silc_server_close_connection if the funtion
1601 silc_server_free_sock_user_data has not been called.
1602 Affected file silcd/server.c.
1604 * Generic tasks cannot be deleted using the del_by_fd
1605 task deleting function since generic tasks does not match
1606 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1608 * Added a notion to SILCOPER help file that the SILCOPER works
1609 only on router server, not on normal server.
1611 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Added for WIN32 support for the new scheduler as well.
1614 Affected file lib/silcutil/win32/silcwin32schedule.c.
1616 * Fixed the SHA1 implementation to work on various platforms.
1618 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1621 API. It is part of the scheduler now. Everything else is
1622 as previously but some functions has changed their names.
1623 Checkout the lib/silcutil/silcschedule.h for the interface.
1624 Updated all applications to use the new interface. Affected
1625 files are lib/silcutil/silcschedule.[ch].
1627 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Found a bug in the SKE implementation. The HASH value,
1630 specified by the protocol, was not computed correctly. The
1631 public key of the responder was not added to the computation
1632 even though it is mandatory. Affected file lib/silcske/silcske.c.
1633 This unfortunately causes incompatibilities with older
1634 clients and servers.
1636 * Added WIN32 specific network init and uninit functions:
1637 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1638 the Winsock2. Affected file lib/silcutil/silcnet.h and
1639 lib/silcutil/win32/silcwin32net.c.
1641 * Set the socket always to nonblocking mode on WIN32 after
1642 reading data or writing data. Affected file is
1643 lib/silcutil/win32/silcwin32sockconn.c.
1645 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed various compilation problems under WIN32. Affected
1648 files lib/silcutil/win32/silcwin32thread.c and
1649 lib/silcutil/win32/silcwin32schedule.c.
1651 * Removed all _internal.h #includes from public header
1652 files. Internal headers must never be included from
1655 Removed also the lib/silcske/payload_internal.h file.
1657 * All include files that may be needed (public and some others
1658 included by the public headers) by application developers are
1659 now copied to the ./includes directory. It does not copy any
1660 internal headers. Affected file Makefile.defines.pre and all
1661 Makefile.am's under lib/ and subdirs.
1663 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Do not change the ~/.silc directory's permissions automatically.
1666 Affected file irssi/src/silc/core/clientutil.c.
1668 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Do not cancel the protocol in silc_server_close_connection
1671 it might cause recursion. Now cancelled in the function
1672 silc_server_free_sock_user_data. Affected file silcd/server.c.
1674 * Fixed the silc_server_remove_clients_by_server to regenerate
1675 the channel keys correctly finally. Added also new function
1676 silc_server_remove_clients_channels to actually do it.
1677 Affected file silcd/server.c.
1679 * Fixed the silc_server_new_channel to not crash by giving
1680 wrong router to the new channel. Affected file is
1681 silcd/packet_receive.c.
1683 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1686 which is given as argument to the silc_client_alloc now.
1687 It can be used to configure the client and set various parameters
1688 that affect the function of the client.
1690 * The USERS command in server did not check whether the channel
1691 is private or secret. Affected file silcd/command.c.
1693 * Added new argument to the USERS command in protocol specification.
1694 The USERS command now can take the channel name as argument
1695 as well. Added support for this in client and server and
1696 updated the protocol specs.
1698 * Completed the GETKEY command in client. It can be now used
1699 to fetch also servers public key not only some clients.
1700 Affected files lib/silcclient/command[_reply].c.
1702 * Added silc_client_get_server to return server entry by the
1703 server name. Affected files lib/silcclient/silcapi.h and
1706 * Redefined the IDENTIFY command in protocol specification to be
1707 more generic. It now can be used to query information about
1708 any entity in the SILC Network, including clients, servers and
1709 channels. The query may be based either the entity's name
1710 or the ID. Added support for this in both client and server.
1712 Affected files silcd/command.c and lib/silcclient/command.c
1713 and command_reply.c.
1715 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1716 the _from_client and _from_server functions. Affected file
1719 * Added silc_client_get_channel_by_id_resolve to the file
1720 lib/silcclient/silcapi.h to resolve channel information by
1721 its ID. Added also silc_client_get_channel_by_id that
1722 does not resolve it from the server.
1724 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Added SilcServerEntry context into the client library
1727 to represent one server. The INFO command now allocates
1728 these to save the resolved server info. For now on the
1729 client library will also keep information about servers,
1730 connected and resolved with INFO.
1732 The INFO command now allocates the SilcServerEntry context
1733 and saves the server info there. The COMMAND_REPLY in
1734 the INFO now returns the parameters to application in
1735 same order as defined in the protocol specification.
1737 The entries are cached in the client->server_cache.
1739 * The INFO command is now issued after received the Client ID
1740 from the server. Affected file lib/silcclient/client.c.
1742 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1743 to the application as the mode changer might be server.
1744 It is guaranteed that NULL is not returned anymore to the
1745 application. Affected file lib/silcclient/client_notify.c.
1747 The ID Type is now also passed to the application so that
1748 it can check whether the returned entry is SilcClientEntry
1751 Added new function silc_client_get_server_by_id to return
1752 the server entry by ID. Affected files are the
1753 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1755 * Do not create the channel in the Irssi SILC Client when issuing
1756 the JOIN command but when received the sucessful JOIN command
1757 reply. Otherwise the channel might get created even though we
1758 could not join it. The Affected file is
1759 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1761 * Fixed a channel joining bug in router. The router must also
1762 check the channel modes, invite and ban lists etc. when serving
1763 the JOIN command sent by normal server. Affected file is
1764 silcd/command.c. The router now resolves the client's
1765 information from the server who sent the JOIN command if it
1766 does not know it, and processes the JOIN command only after
1769 * Changed the SilcCommandCb to take new argument; void *context2.
1770 Affected file lib/silccore/silccommand.h
1772 The second argument in the command callbacks in the server now
1773 includes the SilcServerCommandReplyContext if the command was
1774 called as pending command callback from the command reply.
1775 Otherwise it is NULL. When called as pending the status of the
1776 command reply will be checked and if it was erronous the
1777 error will be sent to the original sender of the command.
1778 This way the client always receives the error messages even
1779 though the server was actually the one who received the error
1780 when it resent the command to router, for example. Affected
1781 files silcd/command[_reply].[ch].
1783 * Fixed sending WHOWAS command's error message to client if
1784 the requested client could not be found. It was missing.
1787 * Changed the CMODE and CUMODE commands reply arguments in the
1788 protocol specification. The Channel ID is now sent in both
1789 of the commands to identify the channel. Implemented this
1790 new feature to the client and server. Affected files
1791 lib/silcclient/command_reply.c and silcd/command.c.
1793 * Made better checks for invite and ban lists in the JOIN
1794 command in server. Affected file silcd/command.c.
1796 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * The server now performs the incoming host IP/DNS lookup
1799 using the silc_socket_host_lookup and thus does not block
1800 the server anymore. Affected file silcd/server.c.
1802 * Completed the multi-thread support for SILC Scheduler in
1803 the lib/silcutil/silcschedule.c.
1805 * Fixed the configure.in.pre to detect the pthread correctly
1808 * Fixed a deadlock in silc_task_queue_wakeup in the file
1809 lib/silcutil/silctask.c.
1811 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Added new function silc_schedule_wakeup that is used in
1814 multi-threaded environment to wakeup the main thread's
1815 schduler. It needs to be used when a thread adds a new task
1816 or removes a task from task queues. After waking up, the
1817 scheduler will detect the task queue changes. If threads
1818 support is not compiled in this function has no effect.
1819 Implemented the wakeup mechanism to both Unix and WIN32
1820 systems. Affected files are lib/silcutil/silcschedule.[ch],
1821 lib/silcutil/unix/silcunixschedule.c and the
1822 lib/silcutil/win32/silcwin32schedule.c.
1824 * Added new function silc_task_queue_wakeup to wakeup the
1825 scheduler by the specified task queue. Affected file
1826 lib/silcutil/silctask.[ch].
1828 * The silc_socket_host_lookup_start now wakes up the scheduler
1829 after adding the timeout task. Affected file is
1830 lib/silcutil/silcsockconn.c.
1832 * The silc_socket_host_lookup is synchronous now if the threads
1833 support is not compiled in. However, the callback is still
1834 called asyncronously through the scheduler, anyway. Affected
1835 file lib/silcutil/silcsockconn.c.
1837 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Added new function silc_socket_host_lookup to perform
1840 asynchronous IP and FQDN lookups for the socket connection.
1841 Affected files lib/silcutil/silcsockconn.[ch].
1843 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1846 that may or may not compile the mutex support in.
1848 Changed the silc_mutex_alloc interface. It allocates the
1849 mutex now to the sent pointer and returns TRUE or FALSE.
1851 Affected file lib/silcutil/silcmutex.h.
1853 * Wrote the SILC Task Queue interface to support multi-threads.
1854 Affected file lib/silcutil/silctask.[ch].
1856 * Wrote the SILC Scheduler to support multi-threads. Affected
1857 file lib/silcutil/silcschedule.c.
1859 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1862 in lib/silcutil/win32/.
1864 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Defined SILC Mutex API and SILC Thread API and implemented
1867 them for Unix. Affected files are
1868 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1869 lib/silcutil/unix/silcunixmutex.c and
1870 lib/silcutil/unix/silcunixthread.c.
1872 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Fixed the silc_server_remove_clients_by_server's channel
1875 key re-generation. The hash table handling was incorrect
1876 and would not work with many channels. Affected file is
1879 * Fixed some memory leaks around the server code.
1881 * Rewrote the silc_server_get_users_on_channel to support IPv6
1882 based Client ID's. Affected file silcd/server.c.
1884 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1885 specification. However, a separate document must be written
1886 to define the detailed signing procedure and the payload
1887 associated with the flag. Defined the flag to the
1888 lib/silccore/silcchannel.h as well.
1890 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Changed the dynamic tables to static size tables in the
1893 lib/silccrypt/silchmac.c.
1895 * Removed GCC dependencies from the code. A patch by cras.
1897 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Do not show the error "Error receiving packet bla bla"
1900 in server if it really was not an error (-2 means that reading
1901 is pending). Affected file silcd/server.c.
1903 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Fixed a possible crash in silc_server_remove_clients_by_server
1906 in silcd/server.c. Fixed there also some memory leaks.
1908 * Fixed the silc_idlist_replace_client_id. It could replace
1909 wrong key in the hash table. Affected file silcd/idlist.c.
1911 * Do not check whether there are global users on the channel
1912 if the channel->global_users is FALSE. Affected functions
1913 silc_server_remove_from_one_channel and
1914 silc_server_remove_from_channels in silcd/server.c. Also,
1915 do not check if the removed client is local as we can be
1916 sure that global client was not removed from the channel
1917 and checking for global users is not needed.
1919 * The silc_server_remove_clients_by_server now re-generates
1920 the channel keys correctly for those channels that had
1921 clients removed from them. Affected file silcd/server.c.
1923 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Found the reason of random crashes in the server. We weren't
1926 ignoring the SIGPIPE signal (which can be sent in write())
1927 and it crashed the server. Affected file silcd/silcd.c.
1929 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Assure that sock->user_data is not NULL in the function
1932 silc_server_packet_send in silcd/packet_send.c.
1934 * Disconnect the remote connection if it could not be added
1935 to any ID lists in the server. The affected file is
1938 * Check in silc_server_packet_send[_real/dest] that the
1939 socket is not disconnecting and ignore the data if it is.
1940 Affected file silcd/packet_send.c.
1942 * Define inline to __inline on native WIN32 compilation.
1943 Affected file includes/silcwin32.h.
1945 * Added some explicit type casts for inline code since MSVC
1946 require them. Affected files lib/silcutil/silcbuffer.h,
1947 lib/trq/silcdlist.h and lib/trq/silclist.h.
1949 * Print warning in log files from now on if the packet
1950 decryption fails. Affected file silcd/server.c.
1952 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Changed the `say' client operation's interface to accept
1955 new `type' argument to indicate the type of the message sent
1956 by the library. The application may filter the library's
1957 messages according the type. The affected file is the
1958 lib/silcclient/silcapi.h.
1960 * Added two new functions to lib/silcclient/silcapi.h:
1961 silc_client_del_client and silc_client_del_client_by_id.
1962 Affected file lib/silcclient/idlist.c.
1964 * Moved the clientincludes.h from includes/ to silc/ and
1965 serverincludes.h from includes/ to silcd/.
1967 * The modes for the CMODE and CUMODE are now passed as
1968 uint32 for application with COMMAND_REPLY. The affected
1969 file is lib/silcclient/command_reply.c.
1971 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * /WHOIS without arguments shows client's own information.
1974 Affected file lib/silcclient/command.c.
1976 * Changed PING to not accept any arguments. The specs
1977 says that client can ping only the connected server so
1978 requiring an argument is not needed. Affected file is
1979 lib/silcclient/command.c.
1981 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Fixed a fatal bug in private message sending and reception
1984 encryption and decryption when using private message keys.
1985 The implementation was incorrect and did not follow the
1986 specification. It causd that some of the message were
1987 lost since it did not use the sending and receiving keys
1988 as the protocol suggests. This has been fixed and will cause
1989 incompatibilities with older clients when sending private
1990 message encrypted with private message keys. Affected files
1991 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1992 and various other in Irssi SILC Client.
1994 Added `responder' boolean argument to the functions
1995 silc_client_add_private_message_key[_ske] to indicate when
1996 the key is added as responder or initiator of the key
1999 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * Removed the silc_ske_check_version function and created
2002 a SilcSKECheckVersion callback. Added also a function
2003 silc_ske_set_callbacks that is now used to set all SKE
2004 callbacks. The callback functions are not given to
2005 the SKE functions anymore, but this function is used to
2008 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2010 * Added `silc_version' argument to the silc_client_alloc
2011 to define the version of the application for the library.
2012 The library will use the version string to compare it
2013 against the remote host's (usually a server) version
2014 string. Affected file lib/silcclient/silcapi.h
2016 * Added the KE protocol context to Key Agreement context
2017 in client library so that we can abort the SKE if it
2018 is in process when we get timeout. Affected file is
2019 lib/silcclient/client_keyagr.c.
2021 * Do not resolve the client ID forever if it returns in the
2022 first time that such client does not exist. This was done
2023 for example with private message. Affected file is
2024 lib/silcclient/client_prvmsg.c.
2026 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Do not add regex.h for WIN32. The affected file
2029 includes/silcincludes.h.
2031 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2032 not work yet 100%. It generates the DLL's automatically
2033 when compiling with --with-win32 under cygwin.
2035 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * lib/contrib/regex.c is not compiled on WIN32.
2039 * Added silc_net_get_socket_opt function to the
2040 lib/silcutil/silcnet.h.
2042 * Added includes/silcwin32.h for WIN32 specific includes
2045 * Do not use ptime structure or any of the posix process
2046 functions on WIN32 in lib/silccrypt/silrng.c.
2048 * Added silc_gettimeofday to provide generic function
2049 for struct timeval on all platforms. Added the function
2050 to lib/silcutil/silcutil.h.
2052 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2055 library as they clearly belong there. As a plus side we
2056 can make the actual socket connection routines platform
2059 Added also new generic function silc_socket_read and
2060 silc_socket_write (that used to be silc_packet_[read/write].
2061 The implementation of these are platform specific.
2063 * Added WIN32 specific routines of silc_socket_[read/write]
2064 to lib/silcutil/win32/silcwin32sockconn.c.
2066 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Added preliminary support for native WIN32 compilation under
2069 cygwin (using the -mno-cygwin option for GCC) to the
2070 ./configure.in.pre. The --with-win32 now prepares the
2071 compilation for native WIN32.
2073 * Rewrote the SILC Scheduler interface in the file
2074 lib/silcutil/silcschedule.h. The scheduler is now context
2075 based and does not have anymore any global static scheduler.
2076 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2077 and created lib/silcutil/win32 directory for WIN32 based
2080 * Added Unix specific network routines to the
2081 lib/silcutil/unix/silcunixnet.c and the old
2082 lib/silcutil/silcnet.c includes now only generic routines.
2084 Added WIN32 specific network routines to the
2085 lib/silcutil/win32/silcwin32net.c.
2087 * Added Unix specific utility functions from the
2088 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2090 * Added WIN32 SILC Scheduler to the file
2091 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2094 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Do not handle JOIN notify in the server if the target client
2097 is not registered (idata->registered == FALSE). The affected
2098 file is silcd/packet_receive.c.
2100 * Update the nickrec->founder in event_cumode in the Irssi SILC
2101 client. Affected file irssi/src/silc/core/silc-channels.c.
2103 * Fixed the CUMODE_CHANGE notify handling in the server when
2104 server and router are announcing their clients on channels.
2105 Now the mode changes are saved and notified correctly. The
2106 affected file is /silcd/packet_receive.c.
2108 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2109 They really did not replace the cache entry in the ID Cache.
2110 Now they do that. Affected file silcd/idlist.c.
2112 * Fixed the KICK notify handling in the Irssi SILC client to
2113 update the channel records so that the kicked client does not
2114 appear to be on the channel. The affected file is
2115 irssi/src/silc/core/silc-channels.c.
2117 * Always update the conn->current_channel when executing command
2118 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2120 * Fixed the KILL notify handling in Irssi SILC client to remove
2121 the killed client on all channels.
2123 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Fixed the silc_parse_command_line to remove extra spaces
2126 from the start and end of the arguments. Affected file is
2127 lib/silcutil/silcutil.c.
2129 * Cancel and free any active protocol in the function
2130 silc_server_close_connection. Affected file silcd/server.c.
2132 * Cancel and free any active protocol in the function
2133 silc_client_close_connction. Affected file is
2134 lib/silcclient/client.c.
2136 * Do not execute the KILL command for clients that are in
2137 history (ie. they are not in the network). Affected file is
2140 * Fixed KILL notify handling, client does not crash anymore.
2141 Affected file irssi/src/silc/core/silc-channels.c.
2143 * Reduced the default packet buffer size from 2048 to 1024 in
2144 lib/silccore/silcpacket.c.
2146 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2147 counter to the SKE context that is incresed when the SKE library
2148 performs async operation outside the library. If the outside
2149 process frees the SKE context and FREED status will be set
2150 and the library will detect after the sync operation that the
2151 libary is freed. The affected files are
2152 lib/silcske/silcske[_status].[ch].
2154 * Resolve the client entry information in the function
2155 silc_client_channel_message to assure that NULL pointer is not
2156 passed as client entry to the application. */
2158 * Fixed the task timeout calculation to assure that there is
2159 never negative timeouts. The affected file is
2160 lib/silcutil/silcschedule.c.
2162 * Fixed the channel user mode notification sending in server.
2163 It was sent point-to-point to the router (or to server by router)
2164 but it needs to be destined to a channel. The routines now
2165 supports sending the channel user mode notifys to the channels
2166 when announcing clients and channels. Affected files are
2167 silcd/server.c and silcd/packet_receive.c.
2169 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2170 It did not actually replace the old channel entry in the cache.
2171 Affected file lib/silcclient/client_notify.c.
2173 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Fixed a possible crash in silc_packet_send_prepare. It now
2176 assures always that there is enough space in the buffer and
2177 at the tail area of the buffer (for MAC).
2179 Fixed the inbound buffer reallocation in silc_packet_read.
2180 It was old code and did not handle the reallocation correctly.
2183 The affected file is lib/silccore/silcpacket.c.
2185 * Fixed buffer overflow in silc_parse_nickname in the file
2186 lib/silcutil/silcutil.c.
2188 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * make install generates new server keys only if there is not
2193 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2195 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2196 Added check that if the NOREPLY is set then we will not send
2197 the away message. This avoids infinite loop of away messages
2198 if both clients are away. The affected file is
2199 lib/silcclient/client_prvmsg.c.
2201 * Fixed client crash if /NICK was given without arguments.
2202 Affected file lib/silcclient/command.c.
2204 * Server does not send the invite list in INVITE command back
2205 to the client if the list was not altered. Added this notion
2206 to the protocol spec as well. Affected file silcd/command.c.
2208 Fixed possible crash in INVITE command by checking the
2209 value of silc_server_get_client_route command.
2211 * Fixed the INVITE notify type handling. The arguments are now
2212 taken in correct order and client does not crash. The affected
2213 file is irssi/src/silc/core/silc-channels.c.
2215 Removed the "Inviting xxx to channel" message from the
2216 client library away and let the application handle it.
2217 Affected file lib/silcclient/command.c. Added that message
2218 to Irssi SILC client's message formats.
2220 * Fixed CMODE command crash in client. It now checks the
2221 amount of arguments correctly and does not crash. The affected
2222 file is lib/silcclient/command.c.
2224 * Do not create new channel automatically in silc_channels_join
2225 but check whether the channel by that name already exists.
2226 Affected file irssi/silc/core/silc-channels.c.
2228 * Do not send the SERVER_SIGNOFF to router if the disconnected
2229 entity was the router. Affected file silcd/server.c.
2231 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2232 SILC client as it was missing from there.
2234 Added the handling of the KICK notify to the Irssi SILC client
2235 as it was missing. Added "you have been kicked" message to
2236 Irssi SILC client's message modules formats.
2238 Added the handing of the KILL notify to the Irssi SILC client
2239 as it was missing. Added the kill message module formats
2242 The affected file is irssi/src/silc/core/silc-channels.c.
2244 * The router did not save the channel mode the server announced.
2245 Affected file silcd/packet_receive.c.
2247 * Fixed a possible crash in INFO command in server. If the
2248 server did not provide the server info it crashed. Affected
2249 file silcd/command.c.
2251 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Fixed the GETKEY command in the server to check also the
2254 global list. Otherwise the GETKEY would not work correctly
2255 in normal SILC server. Affected file silcd/command.c.
2257 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Fixed GETKEY crash, it crashed if the command did not succseed.
2261 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2263 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2264 is now real and not just an macro interface to GMP.
2266 Removed the entire GMP from the source tree and imported new
2267 NSS MPI library instead. Reason for removing GMP is that it is
2268 extremely large and compiles extremely slow. The NSS MPI
2269 is only a few files and compiles in less than 10 seconds.
2270 The speed is also about the same as GMP. The MPI is imported
2271 to lib/silcmath/mpi.
2273 If the system has GMP installed we will still use the GMP.
2274 If it is not then the NSS MPI will be compiled.
2276 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Merged a long nickname (127 characters long) crash bugfix from
2279 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2281 * Merged a freed memory reference bugfix from Irssi CVS tree.
2282 Affected file irssi/src/core/commands.c.
2284 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Added the server's public key sving and verification to the
2287 server when performing the SKE. This was missing and the
2288 remote server's (or router's) public key was accepted without
2289 checking whether we have it previously or trust it at all.
2290 Affected file silcd/protocol.c.
2292 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Check in the silc_server_timeout_remote if protocol is active
2295 and make sure that the protocol's final callback is called so
2296 that all memory if freed. Affected file silcd/server.c.
2298 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * silc_server_whois_send_reply crashed the server if the nickname
2301 was 127 characters long. Affected file silcd/command.c.
2303 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Added sanity check to the silc_server_new_client. If the hostname
2306 is provided inside username then check that the provided hostname
2307 really is the same as the resolved one. If the hostname was not
2308 resolved then check it from the public key. Affected file is
2309 silcd/packet_receive.c.
2311 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2312 if the server disconnected us and the connection is not valid
2313 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2315 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2316 the library to the lib/silcutil/silcutil.[ch].
2318 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Close log file after open. Affected file
2321 lib/silcutil/silclog.c.
2323 * Check whether sock == NULL in silc_client_send_packet and return
2324 if it is. Affected file lib/silcclient/silcclient.c.
2326 * Check rec->entry == NULL in the Irssi SILC Client before
2327 sending the channel message. Affecte file is
2328 irssi/src/silc/core/silc-servers.c.
2330 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Merged a splitted window bugfix from Irssi CVS tree. The
2333 affected file is irssi/src/fe-text/textbuffer-view.c.
2335 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2336 It did not print nickname.
2338 * Improved the distributions system a bit.
2340 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2342 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2343 irssi/src/fe-text/gui-window.c.
2345 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2346 to in-active server. The affected file is
2347 irssi/src/silc/core/client_ops.c.
2349 * Resolve the client in USERS command reply if the entry does
2350 not have username resolved. The affected file is
2351 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2352 command to WHOIS command to really resolve stuff. The USERS
2353 is not used any more in any critical section so WHOIS can
2354 be used even though it might be slower than IDENTIFY.
2356 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2359 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Changed the protocol API a bit more consistent in the
2362 lib/silccore/silcprotocol.[ch].
2364 * Changed the following headers to ROBODoc format:
2366 lib/silccore/silcpayload.h
2367 lib/silccore/silcprotocol.h
2368 lib/silccore/silcsockconn.h
2370 All core library headers are now formatted.
2372 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Fixed a bug in Irssi SILC client; do not show that you are
2375 server/router operator if you really are not. Affected file is
2376 irssi/src/silc/core/client_ops.c.
2378 * Renamed silc_command_free_payload to silc_command_payload_free.
2379 Affected file lib/silccore/silccommand.h
2381 * Added silcmath.h to include the prototoypes of various routines
2382 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2385 * Changed the following headers to ROBODoc format:
2387 lib/silccore/silcchannel.h
2388 lib/silccore/silccommand.h
2389 lib/silccore/silcid.h
2390 lib/silccore/silcidcache.h
2391 lib/silccore/silcmode.h
2392 lib/silccore/silcnotify.h
2393 lib/silccore/silcpacket.h
2394 lib/silcmath/silcmath.h
2396 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Added checking to the server code not to start the server if
2399 ciphers and stuff are not configured properly. Affected files
2400 silcd/serverconfig.[h] and silcd/server.c.
2402 * Changed the layout of the header files of the public interfaces
2403 in the SILC libraries. The new layout supports ROBODoc
2404 documentation tool (and some others) so that it is easy to create
2405 a library reference manual. All the other headers and source
2406 code must still follow the CodingStyle document. Also source
2407 code must not include these ROBODoc stuffs, only the headers.
2408 Furthermore, all public interface headers must now be named
2409 by using `silc' prefix, example: silcapi.h, silccipher.h.
2410 Some files were renamed due to this. All the other headers
2411 must not be used as public interfaces. I will update the
2412 CodingStyle document later. Changed following headers, so far:
2414 lib/silcclient/silcapi.h
2415 lib/silccore/silcauth.h
2416 lib/silccore/silcprivate.h
2417 lib/silccrypt/silcdh.h
2419 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Removed silc_client_packet_send_flush from the client library
2424 as it is not needed. Affected file lib/silcclient/client.[ch].
2426 * Added printing of message of unresolved authentication method
2427 to the Irssi SILC client. Added it to the module formats.
2428 Removed the same message from the client library.
2430 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Added new distribution feature, DISTLABEL. Every distribution
2433 can define own preprocessor label that can be used in the
2434 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2435 file distributions, acconfig.h.pre and prepare.
2437 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Added Makefile.defines_int to include the actual definitions
2440 for Makefile.defines.in. Tested the new distribution system,
2441 created distributions and tested installation.
2443 * Added AWAY message printing to the Irssi SILC client. Added
2444 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2446 * Added SCONNECT command to call the SILC's CONNECT command.
2447 Cannot use CONNECT directly since Irssi uses that internally.
2448 Affected file irssi/src/silc/core/silc-servers.c.
2450 Added ACTION local command. It is same as ME command but takes
2451 the channel as mandatory argument.
2453 Rewrote some of the Irssi's help files to suite for SILC
2456 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2458 * Added Makefile.defines[.in] that should for now on be included
2459 in all Makefile.am file in the source tree. That file includes
2460 all common compilation definitions for SILC source tree.
2462 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Minor changes to the ./prepare script to change the package
2465 name according the distribution name to the configure.in.
2467 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Created new distribution system. Added file `distributions'
2470 that defines all the distributions that can be created out of
2471 the SILC source tree. The ./prepare script now reads that
2472 file to determine how to prepare the distributions. The
2473 first argument to the ./prepare is the name of the distribution
2474 and second is the version of the distribution. If given
2475 without arguments it creates the default (toolkit) distribution
2476 with the default version (defined in ./prepare).
2478 All Makefile.am files that are subject to the distributions
2479 are now named as Makefile.am.pre. These are ./Makefile.am
2480 and lib/Makefile.am. Others may be changed later.
2482 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Added invite list, ban list, some key management and connection
2485 error message printing to module formats in the Irssi SILC client.
2487 * Added new silc_client_set_away_message to set the away message
2488 that is back to the person who sent private message. The
2489 affected file lib/silcclient/silcapi.h and the
2490 lib/silcclient/client_prvmsg.c.
2492 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Fixed the private message sending in the Irssi SILC client,
2495 added local command KEY to the Irssi SILC client.
2497 Added key management and key agreement message formats to the
2498 irssi/src/fe-common/silc/module-formats.[ch].
2500 Added USERS (alias WHO) printing, server/router operator
2501 indication and LIST command printing to the module formats.
2503 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Fixed channel joining notify handling, cumode notify handling
2506 from Irssi SILC client.
2508 * Added SILC specific module-formats to the Irssi SILC client so
2509 that SILC specific message hilighting, colors etc is possible.
2510 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2512 Added channel mode, channel user mode, actions, notices,
2513 whois and whowas printing to the the module-formats.c.
2515 * Fixed a bug in channel deletion in the server. The channel
2516 is not left to the cache even if the channel founder auth mode
2517 is set when there are no users anymore on the channel. Affected
2518 file silcd/server.c.
2520 * The silc_net_localhost now resolves the entire hostname including
2521 the domain name. Affected file lib/silcutil/silcnet.c.
2523 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Changed the ask_passphrase client operation to be ascynchronous.
2526 It has now a completion callback and a context that the
2527 application must call after it has got the passphrase from
2528 the user. Affected files lib/silcclient/silcapi.h,
2529 lib/silcclient/protocol.c, lib/silcclient/command.c and
2532 Added SilcAskPassphrase callback that the application calls
2533 to deliver the passphrase to the library.
2535 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2536 The public key verification and especially a certificate
2537 verification is asynchronous procedure.
2539 Added new SILC_SKE_STATUS_PENDING status to indicate the
2540 request is pending and a callback will be called to finalize
2543 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2544 indicate that remote end did not send its public key (or
2545 certificate), even though we require it. Added check for this
2546 condition in the SKE. This was a security bug, now fixed.
2548 Defined new SilcSKEVerifyCbCompletion callback that is called
2549 when the verification process is completed.
2551 The affected files lib/silcske/silcske_status.h and
2552 lib/silcske/silcske.[ch].
2554 * Changed the verify_public_key client operation to be async
2555 as well. Defined SilcVerifyPublicKey callback that is used to
2556 indicate the success of the public key verification process.
2558 Changed the server and client to use the new async client
2561 * Changed the Irssi SILC client's internal scheduler to be called
2562 twice as many times as it used to be. As a result the client
2563 should be a bit faster now. Affected file is
2564 irssi/src/silc/core/silc-core.c.
2566 * Added support to Irssi SILC client of asynchronous public key
2567 verification and passphrase inquiry. Affected file is
2568 irssi/src/silc/core/silc-core.c.
2570 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Do not say "You have left channel %s" in client library.
2573 Moved it to the application. Affected files are
2574 lib/silcclient/command.c and silc/client_ops.c.
2576 * Fixed silc_client_get_clients. Command context was not
2577 duplicated and was freed memory in the callback. Affected
2578 file lib/silcclient/idlist.c.
2580 * Do not say "you are now talking..." on JOIN command in the
2581 client library. The appliation must handle it.
2583 * Do not say ".. changed topic to" in command reply in the
2584 client libary. The application must handle it.
2586 * Fixed TOPIC command sending in the client library.
2588 * Fixed a memory leak in silc_client_command_free in the file
2589 lib/silcclient/command.c.
2591 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Imported a modified version of Irssi client to the source tree.
2594 The Irssi will be used to create a new client called
2595 Irssi SILC. Imported to irssi/.
2597 Added silc_core_init_finish function to the Irssi. Affected
2598 file irssi/configure.in.
2600 A lot changes in the Makefile.ams around the irssi tree.
2602 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Do not rehash if the new size is same as the old size of the
2605 hash table, in the silc_hash_table_rehash*. The affected file
2606 lib/silcutil/silchashtable.c.
2608 * Replaced hash_table_del_by_context calls from the server
2609 (when channel->user_list and client->channels) to the
2610 hash_table_del as it is sufficient and faster.
2612 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Added silc_hash_table_list, silc_hash_table_get and the
2615 SilcHashTableList structure to provide an alternative way to
2616 traverse the hash table. The affected files are
2617 lib/silcutil/silchashtable.[ch].
2619 * Changed the server's idlist routines to use the hash table
2620 routines to optimize the code.
2622 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Replaced the client entry's `channel' list and channel entry's
2625 `user_list' list to hash tables for optimized lookup. Changed
2626 the code to use the hash table interface around the code.
2627 Affected file lib/silcd/idlist.[ch].
2629 * Added `auto_rehash' boolean argument to the function
2630 silc_hash_table_alloc to indicate whether the hash table should
2631 auto-rehash when it thinks is appropriate time. It will
2632 increase the hash table size if the there is twice as much
2633 entries in the table than the size of the table, and will
2634 decrease the size if there are twice as less entries than
2635 the size of the table.
2637 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2641 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * silc_idcache_purge_by_context deletes the entry now by context
2644 as it is supposed to do. Affected file lib/silccore/idcache.c.
2646 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2647 client is not anymore valid (WHOWAS givens the info) and not
2648 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2650 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Removed the `data' and `data_len' arguments from the ID Cache
2653 interfaces and added `name' argument. ID Cache does not handle
2654 anymore the binary data only a names associated with given ID.
2656 * When hashing a Client ID with silc_hash_id the entire ID is
2657 not hashed anymore, instead only the hash of the Client ID is
2658 hashed. This way we can access the Client ID from the cache
2659 with Client ID but with the hash of the ID (which is a hash of
2660 the nickname) as well without any difference in performance.
2662 Added also silc_idcache_find_by_id_one_ext to do one on one
2663 searching when we have the actual ID. Added also function
2664 silc_hash_client_id_compare. The affected files are
2665 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2667 * When hashing the name associated with a ID it is always done
2668 in lowercase. This way we can access the cache without worrying
2669 about case-sensitivity, even though, for example nicknames are
2672 * Fixed a bug in server with channel message sending. It put
2673 wrong ID type as destination ID. The affected file
2674 silcd/packet_send.c.
2676 * silc_idcache_del_by_context now deletes from all hash tables
2677 by context. Affected file lib/silccore/idcache.c.
2679 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Changed the client library to use the new ID Cache interface.
2682 Changes around the source tree.
2684 * Added silc_hash_table_rehash_ext to rehash with specific
2685 hash function. Affected file lib/silcutil/silchashtable.[ch].
2687 * Added silc_hash_string_compare to compare two strings in the
2688 hash table. Affected file lib/silcutil/silcutil.[ch].
2690 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Added new function silc_idcache_del_by_context into the
2693 lib/silccore/idcache.[ch].
2695 * Changed the server's ID list routines to use the new ID Cache
2696 interface. Changes around the source tree.
2698 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Added silc_hash_table_del[_by_context]_ext functions in to the
2701 lib/silcutil/silchashtable.[ch].
2703 Removed silc_hash_table_find_all* routines and added new
2704 silc_hash_table_find_foreach to replace them.
2706 Added silc_hash_table_replace_ext function as extended
2707 replacing function. Separated the simple hash table interface
2708 from the extended hash table interface in the file
2709 lib/silcutil/silchashtable.h.
2711 * Fixed minor bugs and changed it to use some of the new
2712 hash table functions in lib/silccore/idcache.c
2714 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Added new function silc_hash_table_find_all to return all keys
2717 in the hash table by the specified key. As the hash table is
2718 collision resistant it also makes it possible to have several
2719 duplicate keys in the hash table. This function may be used to
2720 find all of the keys from the hash.
2722 Added user_context arguments to the SilcHashFunction,
2723 SilcHashCompare and SilcHashDestructor to deliver user specified
2726 Added new fuctions silc_hash_table_find[_all]_ext to do
2727 extended lookup with specified hash and compare functions and
2728 specified user contexts.
2730 Added new function silc_hash_table_add_ext to add the key
2731 with specified hash function and user context.
2733 Added new function silc_hash_table_foreach to traverse all
2734 entrys in the hash table. Added SilcHashForeach callback
2737 Added new function silc_hash_table_del_by_context to delete
2738 the entry only if the context associated with the key matches.
2740 Affected files are lib/silcutil/silchashtable.[ch].
2742 * Removed silc_hash_[server/client/channel]_id and added just
2743 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2744 silc_hash_id_compare to compare two ID's using as the hash table
2745 comparison function. Added also silc_hash_data to hash
2746 binary data and silc_hash_data_compare to compare it.
2748 * Removed silc_idlist_find_client_by_hash as it is not needed
2749 anymore. Affected file silcd/idlist.[ch].
2751 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2752 to use internally the SilcHashTable. The new ID Cache is a lot
2753 faster than the old one. Some of the ID Cache interface was also
2754 rewritten and obsolete and stupid functions were removed.
2756 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Added entry_count field to the SilcHashTable to keep the number
2759 of the entries in the table. Implemented the function
2760 silc_hash_table_rehash. Added new function
2761 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2763 Fixed a minor bug in silc_hash_table_free.
2765 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2766 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2767 into the lib/silcutil/silcutil.[ch].
2769 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Implemented a collision resistant hash table into the
2772 lib/silcutil/silchashtable[ch]. See the header and the source
2773 for the SilcHashTable API.
2775 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Merged dotconf version 1.0.2 into lib/dotconf.
2779 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Do not compile anything in lib/silcsim/* if the SIM support
2782 is not enabled. The tree should now compile without problems
2785 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Compiled the SILC under cygwin. Compiled and tested briefly
2788 without problems. More tests needed. The SIMs didn't compile
2791 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2793 * Fixed possible crash in silc_get_username in the
2794 lib/silcutil/silcutil.c.
2796 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Fixed a va_arg in silc/client_ops.c.
2800 * Oops, RC5 routines were named AES and caused some problems
2801 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2803 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Added new SilcIDIP structure into the lib/silccore/id.h and
2806 replaced the old `ip' fields from all SILC ID's to that type.
2807 This is a step towards IPv6 support.
2809 The silc_id_get_len takes now the ID as an extra argument.
2810 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2811 both IPv4 and IPv6 based ID's.
2813 The affected files are lib/silccore/id.[ch] and other files
2814 around the tree using these routines.
2816 * Removed the ID length arguments in server from various
2817 silc_server_send_notify_* routines -> they are not needed
2820 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Fixed memory leak in silc_encode_pem_file in the file
2823 lib/silcutil/silcutil.c.
2825 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Check minor version as well in the SKE. Affected files are
2828 silcd/protocol.c and lib/silcclient/protocol.c.
2830 * Added --identifier option to the server so that an identifier
2831 can be when creating the public key for the server. Affected
2832 file is silcd/silcd.c.
2834 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2835 lib/silccrypt/silcpkcs.c.
2837 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Register default ciphers and stuff when using -C option with
2840 the server. Affected file sildc/silcd.c.
2842 * Put back the servers public key filename format, it is better
2843 than the new one. For now, the client keys are saved with the
2844 new filename format. The affected file silc/client_ops.c.
2846 * Implemented the Cipher API for the rest of the ciphers that
2847 did not implement it or implemented it the wrong way.
2849 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Register default ciphers and stuff when using the -S option
2852 in the client. Affected file silc/silc.c. Same also when
2853 creating new key pair with -C option.
2855 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Fixed the silc_verify_public_key client operation function to
2858 save the public keys differently. The fingerprint is now
2859 used as filename and not the hostname. This way also the
2860 client keys are saved uniquely and not with hostnames. The
2861 affected file is silc/client_ops.c.
2863 * Trimmed the silc_hash_fingerprint function to remove extra
2864 whitespaces from the end of the fingerprint. The affected
2865 file is lib/silccrypt/silchash.c.
2869 * Added silc_cipher_register_default function to register all
2870 default ciphers. It can be used when configuration files
2871 does not exist and the application does not want any specific
2872 ciphers in any specific order.
2874 The SilcDList is now used as silc_cipher_list dynamically
2875 allocated cipher list. Removed the static list all together
2876 and now all ciphers must be allocated to the dynamic list.
2877 The silc_cipher_alloc routine was changed to check only the
2880 All silc_cipher_* routines that used to return int returns
2883 The affected files lib/silccrypt/silccrypt.[ch].
2885 * The same thing was done to silc_hash_* as for silc_cipher_*
2886 routines. Affected files lib/silccrypt/silchash.[ch].
2888 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2889 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2890 Added also silc_pkcs_[un]register[_default] functions.
2891 Removed the data_context from the PKCS API.
2893 * Added silc_hmac_register_default function to register default
2894 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2895 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2896 to unregister all hmacs at once.
2898 * Register the default ciphers, hash functions, PKCSs and HMACs
2899 if client's configuration file does not exist. The affected
2902 * The client did not load the hash functions from the SIM
2903 modules at all. Added support for this. Affected file is
2904 silc/clientconfig.c.
2906 * When decoding public key with silc_pkcs_public_key_decode, check
2907 the supported algorithm only if PKCS are registered. Affected
2908 file lib/silccrypt/silcpkcs.c. The same was done with the
2909 silc_pkcs_private_key_decode.
2911 * Fixed the SILC List routines to keep the list always in order.
2912 It used to change the list's order when traversing the list but
2913 not it preserves the order. Affected file lib/trq/silclist.h.
2915 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Added the client library to use the SilcSocketConnection's
2918 reference counter (by silc_socket_dup) to prevent the bug that
2919 the socket object may be freed underneath async operation.
2921 * The name resolv library checking fixes in the configure.in.pre.
2924 * Created new version of the protocol drafts for future
2925 development. The -03 drafts are the ones that will be changed
2926 in the trunk now and the -02 will remain as they are.
2928 * Send list of CUMODE notifys to the router when announcing
2929 the channel users to the router. Affected file silcd/server.c.
2930 If the router receiving channel founder CUMODE for a channel
2931 that already has channel founder it will send CUMODE notify
2932 to the sender to remove the channel founder rights from the
2933 announced client. Affected file silcd/packet_receive.c.
2935 * The CUMODE notify may now use Server ID as well as the entity
2936 who changes the mode. Updated protocool specs.
2938 * Updated INSTALL and README files.
2940 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * New web pages in the http://silc.pspt.fi. The pages was
2947 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Implemented the [DenyConnectin] config section in the server.
2950 Added silc_server_config_denied_conn to check whether incoming
2951 connection is denied. Affected file silcd/serverconfig.[ch].
2953 * Do not check the ports when checking the incoming configuration
2954 data if the port is 0, meaning any. Affected file is
2955 silcd/serverconfig.c.
2957 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Fixed buffer overflow in silc_string_compare in the file
2960 lib/silcutil/silcutil.c.
2962 * Fixed double free in silc_server_command_leave in the file
2965 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Fixed the version checking in the server. Affected file is
2970 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2972 * Fixed the configuration data fetching when accepting new
2973 connections in the server. Affected file silcd/server.c.
2975 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Added `sender_entry' argument to the function
2978 silc_server_packet_relay_to_channel so that we can check
2979 whether some destination actually belongs to the same route
2980 the sender belongs (ie, we must not resend the packet to the
2981 sender). Affected file silcd/packet_send.[ch].
2983 * Added `servername' field to the SilcClientEntry in the server
2984 to hold the name of the server where client is from. Affected
2985 file is silcd/idlist.h.
2987 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Moved the channel message encrypting in the router betwen
2990 router connections from silc_server_channel_message to the
2991 silc_server_packet_relay_to_channel since we want to check
2992 whether we have anybody channel before encrypting anything.
2993 Affected files silcd/packet_[receive/send].c.
2995 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Fixed the [AdminConnection] server config section to support
2998 multiple entries. Affected file silcd/serverconfig.c.
3000 * Added support into the server to check the validity of the
3001 incoming connection before executing any KE or authentication
3004 * The connection configuration is now saved to the KE and
3005 connection auth protocol contexts and not fetched anymore in
3006 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3008 * The local hosts listenning address and port is also resolved
3009 now when starting the server. We want to have the socket object
3010 to include the real address and port for the listener. Added
3011 new function silc_net_check_local_by_sock into the files
3012 lib/silcutil/silcnet.[ch].
3014 * Fixed a broadcast bug in server -> do not broadcast if we
3017 * Fixed a routing bug. Do not route broadcast packets ever.
3018 Broadcast packets must be processed always and not routed since
3019 they may be destined to some other host than yourself and thus
3020 would get routed without no good reason. Affected file is
3023 * Added function silc_server_config_is_primary_route to check
3024 whether primary router connection has been configured (a router
3025 configuration that we are initiating). If there is not, we
3026 will assume that there is only two routers in the SILC network
3027 and we will use the incoming router connection as our primary
3028 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3030 * Changed the order of the broadcasting. Broadcast _after_ the
3031 packet has been processed not before. Affected file is
3034 * Fixed a [ClientConnection] parsing bug. The port was never
3035 parsed correctly thus resulting to port 0. Affected file
3036 silcd/serverconfig.c.
3038 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3039 argument and did not set the broadcast packet flag. Affected
3040 file silcd/packet_send.c. Fixed same bug in the function
3041 silc_server_send_notify as well.
3043 * If we receive NEW_ID packet for our own ID in the server, ignore
3046 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Removed the nickname from the Private Message Payload.
3051 Updated the code and the protocol specs.
3053 * Updated protocol specs for submitting to the IETF.
3055 * Tweaked the Random Number Generator a bit. Affected file
3056 lib/silccrypt/silcrng.c. Exported a new function
3057 silc_rng_[global]_add_noise which can be used to add more
3060 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Do not parse packets with different timeout when protocol
3063 is active -> may cause problem with rekey. Affected file
3066 * When server receives signoff notify it must not create
3067 new channel key if the client is on any channels since the
3068 sender of the signoff notify will create it.
3070 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Added printing of error messages during SKE protocol from the
3073 failure packet sent by server during SKE. Affected file
3076 * Removed the client's failure_callback handling with timeout
3077 and handle it immediately when received.
3079 * The SKE library returned wrong type in SUCCESS and FAILURE
3080 packets. They must be 32 bit MSB not 16 bit MSB.
3082 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Ok, rewrote the logic of the re-key and now it seems to work.
3085 I tested it on high traffic with frequent re-keys without
3086 problems. Added hmac_receive (and renamed hmac to hmac_send)
3087 in SilcClientConnection in lib/silcclient/client.h and
3088 in SilcIDListData in silcd/idlist.h. Also, removed the
3089 SilcPacketParserContext's cipher and hmac fields as they are
3090 not needed anymore and actually caused some problems when
3091 the ciphers and hmac's changed underneath the packet parser.
3093 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * If re-key protocol is active then process the incoming packets
3096 synchronously since we must assure that icoming packets encrypted
3097 with the old key is processed before the new keys is set to
3098 use. This is true other packets than for REKEY packets.
3099 Affected file silcd/server.c. The same was done to client library
3100 as well, affected file lib/silcclient/client.c.
3102 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Fixed bug in client and server to accept the force send if
3105 the packet is send from silc_[server/client]_packet_process
3106 function. Otherwise the packets are never delivered, oops.
3108 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3110 * Disable force sending of packets when REKEY protocol is active.
3111 We must assure that no packet is sent directly when rekey is
3112 performed. All packets must be sent through packet queue.
3113 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3114 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3115 function is silc_[server/client]_packet_send_real to check
3118 * Replaced the SIM paths from example config files to
3119 /usr/local/modules. Also, make install creates now
3120 /usr/local/silc/logs directory to hold all the SILC server
3123 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Made the configure.in.pre work on Solaris. Patch by salo.
3127 * Made all ciphers compatible with non-x86 machines. Defined
3128 CBC mode macros into lib/silccrypt/ciphers_def.h.
3130 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Fixed the make install.
3134 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * When MAC computation fails the silc_packet_decrypt returned 0
3137 even though it was supposed to return -1. Fixed this. The
3138 affected file is lib/silccore/silcpacket.c.
3140 * Do not replace the config files in /etc/silc (in make install)
3141 if they already exist. Affected file ./Makefile.am.
3143 * Do not send re-key packets immediately but through packet queue.
3144 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3146 * Changed silc_net_check_host_by_sock to return FALSE if the
3147 IP/DNS could not be resolved. Though, it returns the IP address
3148 now even if it could not resolve it (but returns also FALSE).
3149 Affected file lib/silcutil/silcnet.[ch].
3151 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Added silc_pkcs_decode_identifier to decode the public key's
3154 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3155 Added also silc_pkcs_free_identifier. Added also new context
3156 SilcPublicKeyIdentifier.
3158 * Added -S option to the silc client. It is used to dump the
3159 contents of the specified public key file.
3161 * Changed the PKCS api to return the public key length when
3162 setting the public key.
3164 * Fixed a fatal bug in the public and private key file loading.
3165 Affected file lib/silccrypt/silcpkcs.c.
3167 * Execute the packet parsing for client with zero (0) timeout
3168 if the protocol is active. Affected file silcd/server.c.
3170 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Made the key generation options to the silcd program. Added
3173 -C option, equivalent to client's option.
3175 * Added new [ServerKeys] config section to the server. It
3176 configures the server's public and private key.
3178 * Defined generic Public Key Payload into the protocol
3179 specification to send specific type of public keys and
3182 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3183 public key or certificate.
3185 * Implemented the GETKEY command to the server and to the
3186 client library and on user interface.
3188 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Made preliminary `make install' work.
3192 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Added SilcServerRekey context into silcd/idlist.h.
3196 * Added the PFS support as defined in the specification to the
3197 SKE protocol. Affected files lib/silcske/*.c.
3199 * Added `ske_group' field to the SilcServerRekey context to hold
3200 the number of the SKE group that is used with PFS in re-key.
3201 Affected file silcd/idlist.h.
3203 * Added PFS re-key support to the server. Affected file is
3206 * Added silc_protocol_cancel to cancel execution of the next
3207 state of the protocol. Affected file is
3208 lib/silccore/silcprotocol.[ch].
3210 * Added the re-key support with and without PFS to the client
3211 library. Re-key is performed once in an hour, by default.
3213 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3214 Added silc_client_rekey_callback and silc_client_rekey_final.
3215 Affected files are lib/silcclient/protocol.[ch] and
3216 lib/silcclient/client.[ch].
3218 * Removed the `hmac_key' and `hmac_key_len' fields from the
3219 SilcClientConnection structure; not needed. Affected file is
3220 lib/silcclient/client.h.
3224 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Do not ask whether user wants to use the negotiated private key
3227 for private messages, just use it. Affected file is
3228 silc/local_command.c.
3230 * Added `send_enc_key' and `enc_key_len' fields to the
3231 SilcIDListData structure since they are needed in the re-key
3232 phase. Affected file is silcd/idlist.[ch].
3234 * Implemented the simple re-key protocol into the server.
3235 Affected files silcd/server.c and silcd/protocol.[ch]. The
3236 re-key will be performed once in an hour, by default.
3238 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3239 Added silc_server_rekey, silc_server_rekey_callback and
3240 silc_server_rekey_final.
3242 * Removed Tunneled flag from the protocol. Updated the code
3243 and the specifications.
3245 * Adde `pfs' field to the SilcIDListData to indicate whether
3246 the PFS is to be performed in the re-key. Affected file is
3249 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3252 int64 of at least the xintXX size. If void * is less that 4
3253 bytes uint32 * will be used. Defined bool as boolean.
3255 * Changed _ALL_ unsigned long and unsigned int to uint32,
3256 unsgined short to uint16 in the source tree.
3258 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3259 not handle clients that has entry->data.registered == FALSE.
3260 They are not in the network anymore. Affected file is
3263 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Implemented the sending of the SERVER_SIGNOFF notify in the
3266 server. Affected file is silcd/server.c.
3268 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3269 Added also silc_notify_payload_encode_args into the
3270 lib/silccore/silcnotify.[ch].
3272 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3273 Affected file silcd/packet_receive.c.
3275 * Implemented the SERVER_SIGNOFF notify handling in the client
3276 library. Affected file lib/silcclient/client_notify.c. Also,
3277 implemnted the printing of the SERVER_SIGNOFF info to the
3278 application. Affected file silc/client_ops.c.
3280 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3281 if the deleting was successful. Affected file silcd/idlist.[ch].
3283 * Added support for public key authentication in the connection
3284 authentication protocol in the client library. Affected file
3285 lib/silcclient/protocol.c.
3287 * Changed the server's silc_idlist_get_clients_by_* interface
3288 to support already allocated array so that new entries may be
3289 added to pre-allocated array. Affected file silcd/idlist.[ch].
3290 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3291 and command replies.
3293 * All command reply functions in the server now calls the
3294 pending command callback even if error occured. This way the
3295 error will be delivered to the client as well. Affected files
3296 silcd/command.c and silcd/command_reply.c.
3298 * Fixed INFO command to return local server's info if no server
3299 was provided. Affected file lib/silcclient/command.c.
3301 * Removed RESTART command for good. Updated the code and the
3304 * Rewrote parts of the task system. It is a bit simpler now.
3305 Removed unsued task priorities. The affected files are
3306 lib/silcutil/silctask.[ch].
3308 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Moved the USERS printing from the library to the application.
3311 Affected files lib/silcclient/command.c and silc/client_ops.c.
3313 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * Added channel key re-key support. The re-key is perfomed
3318 only by the router and is done once in an hour. Added `rekey'
3319 field to the SilcChannelEntry in the server. Affected files
3320 silcd/server.c and silcd/idlist.h.
3322 * Added silc_task_unregister_by_context into the file
3323 lib/silcutil/silctask.[ch].
3325 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3327 * Added SILC_UMODE_GONE mode to indicate when the client is not
3328 present in the SILC network. Added also support to the local
3329 command AWAY that will set this mode. Added support of showing
3330 "xxx is gone" in WHOIS command. The USERS command shows the
3331 gone status as well.
3333 * Fixed setting server and router operator privileges in the
3334 server's UMODE command. Affected file silcd/command.c.
3336 * Merged the SKE KE1 and KE2 payloads into one payload. The
3337 new KE payload is equivalent to the old KE2 payload.
3339 Cleaned up the SKE Start Payload parsing. It now uses the
3340 simple buffer unformatting to do the parsing. A lot faster
3343 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3344 to the SKE that is used to indicate whether both of the SKE
3345 parties should perform authentication. By default only the
3346 responder performs authentication. By setting this flag also
3347 the initiator must do authentication. By default it is unset
3348 since in normal SKE case, client to server connection, only
3349 the responder should do authentication. When doing SKE between
3350 two clients both should perform authentication. Updated the
3351 code and the protocol specs.
3353 * A little fix to IDENTIFY command in the server. Search the
3354 client first by hash not nickname. Affected file is
3357 * Fixed the silc_client_close_connection to support closing
3358 the client to client connections wihtout deleting too much
3359 data. Affected file lib/silcclient/client.c.
3361 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3362 are received if protocol used to be active but is not anymore
3363 the application would crash due to NULL pointer dereference.
3364 Affected files silcd/server.c and lib/silcclient/client.c.
3366 * Added `hash' field to the SilcClientConnection to include
3367 the hash function negotiated in the SKE protocol.
3369 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3370 to set the channel founder authentication data. A client can
3371 claim the founder rights later by providing the authentication
3372 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3373 This way the channel founder can regain the channel founder
3374 privileges even it is left the channel. This works only on
3375 local server and the client must be connected to the same
3376 server to be able to regain the founder rights. Updated the
3377 protocol specs accordingly.
3379 Added support to the CMODE command in the client to set the
3380 founder auth data. Read the README to see how to set it.
3382 Added support to the CUMODE command to claim the founder
3383 rights. Read the README to see how to do it.
3385 Added support for the founder authentication to the Channel
3386 Entry in the server. Affected file silcd/idlist.h.
3388 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3389 server's CMODE command. Affected file silcd/command.c.
3391 * Added the following new functions into lib/silccore/silcauth.[ch]:
3392 silc_auth_get_method and silc_auth_get_data.
3394 * The server now saves the remote hosts public key to the
3395 SilcIDListData pointer. Affected file silcd/protocol.c.
3397 * The normal server now does not remove the channel entry from
3398 the cache if the founder authentication data is set. It used
3399 to remove it if the founder was the last one on the channel on
3400 the server and left the channel. The auth data is saved and
3401 if the channel is re-joined later the old entry is used with
3402 the old auth data. Affected files silcd/command_reply.c and
3405 * Removed the `pkcs' field from the SilcIDListData structure
3406 in the server; it is not used. Affected file silcd/idlist.h.
3408 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Fixed packet processing on slow links. Partial packets were
3411 never re-processed because the incoming data buffer was cleared
3412 by the application. Application must not directly clear the
3413 sock->inbuf, the packet processing routines handle it. Fixed
3414 this in client library and in server.
3416 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Fixed the WHOIS and IDENTIFY send reply function to really
3419 check whether to send list or just one entry. Affected file
3422 * Cleaned up the LEAVE command's channel key distribution. The
3423 affected file silcd/command.c.
3425 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3426 can enforce the channel mode as well. In that case the ID
3427 includes the ID of the server. The code now enforces the
3428 mode change if the router have different mode than the server.
3430 * The notify client operation with CMODE_CHANGE notify can now
3431 return NULL client_entry pointer if the CMODE was not changed
3432 by client. Application must check for this.
3434 * Added <Server ID> argument to INFO command to support server
3435 info fetching by Server ID.
3437 * Added silc_server_announce_get_channel_users to get assembled
3438 packets of channel users of the specified channel. Affected
3439 file silcd/server.[ch].
3441 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3442 was freed underneath the ID Cache.
3444 * Re-announce clients when the server received CHANNEL_CHANGE
3445 notify from the router. Affected file silcd/packet_send.c.
3447 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3450 crashed since it did not handle the fact that there is no cipher
3451 called "3" and didn't check the error condition. Now fixed.
3453 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3454 flag. It can be used to send message requests.
3456 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Implemented the RESTART command in the client.
3460 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3461 notice type messages. Added notice printing to the user
3464 * The channel keys are not re-generated if the channel's mode
3465 is PRIVKEY, ie private key on the channel exists. Affected
3466 files silcd/server.c and silcd/command.c.
3468 * Fixed a little bug in channel message delivery when channel
3469 private keys are set in the server. Affected file is
3470 silcd/packet_send.c.
3472 * Changed the setting on channel->on_channel = TRUE from the
3473 silc_client_save_channel_key to the JOIN command reply. The
3474 key payload is not received if the private channel key is set.
3475 Affected file lib/silcclient/command_reply.c and the
3476 lib/silcclient/client_channel.c.
3478 * When the CMODE_CHANGE notify is sent and the channel private
3479 key mode is removed the channel key must be re-generated in
3480 other cells as well. Added this support for the router in the
3481 silcd/packet_receive.c.
3483 * Added new local command NOTICE to send notice message on
3484 channel. Affected file silc/local_command.[ch].
3486 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Added new local command ME to the client. It is used to send
3489 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3490 some action. Affected file silc/local_command.[ch].
3492 * Changed channel_message and private_message client operations
3493 to deliver the message flags to the application. Added also
3494 the `flags' arguments to the silc_client_send_channel_message
3495 and silc_client_send_private_message functions. Affected file
3498 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Redefined the Private Message Payload to support private message
3501 keys and to support the new private message flags. Updated
3502 the protocol specs. Flags makes it possible to have for example
3503 CTCP style messages.
3505 * Added new type SilcPrivateMessagePayload and defined an API
3506 for it in the lib/silcclient/silcprivate.[ch].
3508 * Tested private message private keys successfully. Tested the
3509 private message key set, unset and list commands with the new
3512 * Redefined the Channel Message Payload to include the channel
3513 message flags (equal with private message flags) to support
3514 for example CTCP style messages.
3516 * Defined some of the message (for channel and private message)
3517 flags. Updated the protocol specs and added the flags to the
3518 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3520 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Added SilcKeyAgreementStatus type to the key agreement routines
3523 to indicate the current status and error if one occured.
3524 The status types are defined in the lib/silcclient/silcapi.h.
3526 * Added new local command KEY that is used to set and unset private
3527 keys for channels, set and unset private keys for private messages
3528 with remote clients and to send key agreement requests and
3529 negotiate the key agreement protocol with remote client. The
3530 key agreement is supported only to negotiate private message keys,
3531 it currently cannot be used to negotiate private keys for channels,
3532 as it is not convenient for that purpose.
3534 * Fixed a minor pending callback setting bug in the function
3535 silc_client_get_client_by_id_resolve, now the function works.
3536 Affected file lib/silcclient/idlist.c.
3538 * Added function silc_net_get_local_port to get local bound
3539 port by socket. Added to lib/silcutil/silcnet.[ch].
3541 * Added `sockets' and `sockets_count' fields to the SilcClient
3542 object. They hold the sockets of the listenning sockets in
3543 the client. Listenning sockets may be for example the key
3544 agreement server. Affected file lib/silcclient/client.[ch].
3545 Added functions the silc_client_add_socket and the
3546 silc_client_del_socket. They are exported to the application
3549 * Added ~./silc/clientkeys to support other client's public keys.
3551 * Renamed verify_server_key client operation to verify_public_key
3552 and added one argument to indicate the type of the connection
3553 (server, client etc.).
3555 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Added silc_server_connection_auth_request to handle the
3558 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3559 silcd/packet_receive.[ch].
3561 * Added silc_server_send_connection_auth_request into the
3562 silcd/packet_send.c to send the connection auth request packet.
3564 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3567 * Fixed the public key authentication in responder side in the
3568 server. The `auth_data' pointer includes the SilcPublicKey
3569 not the path to the public key. Affected file silcd/protocol.c.
3571 * Implemented the public key authentication in the initiator side
3572 in the server. Affected file silcd/protocol.c.
3574 * Removed the [RedirectClient] config section from the server
3575 configuration. Is not needed and I don't want to implement it.
3577 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Cleaned up the CMODE command in the server. It now works
3580 correctly and supports all the modes defined in the protocol.
3581 Affected file is silcd/command.c.
3583 * Added `hmac_name' field to the SilcChannelEntry in the server
3584 to hold the default HMAC of the channel. It can be set when
3585 creating the channel (with JOIN command). Affected files
3588 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3589 type to indicate the change of the current cipher and hmac
3590 on the channel. Client can safely ignore the <cipher> argument
3591 (if it chooses to do so) since the CHANNEL_KEY packet will
3592 force the channel key change anyway. The <hmac> argument is
3593 important since the client is responsible of setting the new
3594 HMAC and the hmac key into use.
3596 * Fixed the CMODE command in the client library as well.
3598 * Tested CMODE command in router environment successfully.
3600 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Show the version of the remote client (or server) when connecting
3603 to the server. It is logged to the log file. Affected file
3604 is silcd/protocol.c.
3606 * Fixed the KILLED notify handling in the client library. The
3607 client must be removed from all channels when receiving the
3610 Also, do not remove the client entry when giving the KILL
3611 command but when the KILLED notify is received.
3613 * Removed silc_idlist_find_client_by_nickname from the server.
3614 Not needed anymore. Affected files silcd/idlist.[ch].
3616 * Implemented the CHANNEL_CHANGE notify type handling to the
3617 server. Affected file silcd/server.c.
3621 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Added silc_server_send_notify_invite to send the INVITE
3624 notify between routers.
3626 * Implemented the INVITE command correctly to the server.
3628 * Implemented the INVITE notify type handling in the server.
3630 * Implemented the INVITE command to the client library and on the
3633 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Added function silc_server_get_client_resolve to find the
3636 client entry by ID from all ID lists and then resolve it
3637 (using WHOIS) if it cannot be found. Affected file is
3640 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Implemented the BAN command to the client library.
3644 * The JOIN command in the server now checks the invite list
3647 * Changed the silc_command_reply_payload_encode_va and the
3648 silc_command_payload_encode_va to support that if argument is
3649 NULL it ignores and checks the next argument. Affected file
3650 lib/silccore/silccommand.c.
3652 * Added silc_server_send_notify_ban to send the BAN notify
3653 type between routers.
3655 * Chaned the silc_notify_payload_encode to support that if
3656 argument is NULL it ignores and checks the next argument.
3657 Affected file lib/silccore/silcnotify.c.
3659 * Tested ban lists in router environment successfully.
3661 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Implemented BAN command to the server, in silcd/command.[ch].
3665 * Removed the BAN and INVITE_LIST modes from the CMODE command
3668 * Added function silc_string_match to regex match two strings.
3669 Affected files lib/silcutil/silcutil.[ch].
3671 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Redefined parts of the SilcChannelEntry in the server to support
3674 the new ban and invite lists.
3676 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Redefined the INVITE command. The same command can be used to
3679 invite individuals to the channel but also to manage the invite
3680 list of the channel (to add to and remove from the invite list).
3681 Updated the protocol specs.
3683 * Added new command SILC_COMMAND_BAN that can be used to manage
3684 the ban list of the channel. Updated the protocol specs.
3686 * Removed the channel modes: the SILC_CMODE_BAN and the
3687 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3688 in the CMODE command. The equivalent features are now available
3689 using INVITE and BAN commands. Updated the protocol specs.
3691 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3692 in the network about change in the current ban list. The notify
3693 type is not used by the client.
3695 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3696 support the invite lists.
3698 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Added new function silc_string_regexify that converts string
3701 including wildcard characters into regex string that can
3702 be used by the GNU regex library. Added into the file
3703 lib/silcutil/silcutil.[ch].
3705 Added silc_string_regex_combine to combine to regex strings
3706 into one so that they can be used as one regex string by
3707 the GNU regex library. Added into the file
3708 lib/silcutil/silcutil.[ch].
3710 Added silc_string_regex_match to match two strings. It returns
3711 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3713 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Imported GNU regex to the soruce tree into lib/contrib.
3716 Fixed some compiler warning from the regex.c.
3718 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Fixed MOTD command in the server to work in router environment.
3722 * Fixed the MOTD command in the client library to support
3723 the server argument in the command.
3725 * Added `nickname_len' argument to the silc_idlist_add_client
3726 in the server, as the `nickname' argument may be binary data
3729 * Added silc_idlist_get_channels to return all channels from
3732 * Implemented LIST command to the server. Affected file is
3735 * Implemented the LIST command to the client library and on the
3738 * Added [<user count>] argument to the LIST command reply.
3739 With private channels the user count is not shown.
3741 * Updated TODO and README.
3743 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * The client entry's data.registered must be TRUE even with
3746 global client entry on global client list. The data.registered
3747 is used to check whether the client is anymore in the network,
3748 for example with WHOWAS command so it must be valid.
3750 * Fixed the WHOWAS command in the server. It now actually works
3751 in router environment. Added function into silcd/command_reply.c
3752 silc_server_command_reply_whowas_save.
3754 * Added silc_idlist_purge function to the silcd/idlist.c
3755 to periodically purge the ID Cache.
3757 * Fixed INFO command in the server. It works now in router
3758 environment. Added <server name> argument to the INFO command
3759 reply. Updated the protocol specs.
3761 * Fixed minor bug in silc_idcache_purge to not purge if the
3762 expire value is zero.
3764 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3765 they were buggy because of the WHOWAS information.
3767 * Fixed local command MSG to handle the async resolving of
3768 the remote client properly. It used to fail the first MSG.
3769 Affected file silc/local_command.c.
3771 * Added `data_len' field to SilcIDCache context.
3773 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Update TODO. Todo in commands in the server.
3777 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3780 used by routers as broadcast packet to inform other routers
3781 about the changed user mode.
3783 Implemented the notify handling in the server. Affected file is
3784 silcd/packet_receive.c. Added the function
3785 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3787 * Added new generic Channel Payload and deprecated the New Channel
3788 Payload. The New Channel Payload is now the generic Channel
3791 * Added new argument `mode' to the silc_server_send_new_channel
3792 as it is required in the Channel Payload now.
3794 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3795 and created a new and real SilChannelPayload to represent the
3796 new generic Channel Payload. Implemented the encode/decode
3797 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3799 * Added silc_server_get_client_channel_list to return the list
3800 of channels the client has joined for WHOIS command reply.
3801 Affected file silcd/server.[ch].
3803 * Implemented the channel list sending in the WHOIS command reply
3804 in server and in the client.
3806 Implemented the channel list displaying on the user interface
3807 as well. Affected file silc/client_ops.c.
3809 * Added silc_channel_payload_parse_list to parse list of Channel
3810 Payloads. It returns SilcDList list of SilcChannelPayloads.
3811 Client for example can use this function to parse the list of
3812 channels it receives in the WHOIS command reply. The caller
3813 must free the list by calling silc_channel_payload_list_free.
3814 Affected files lib/silccore/silcchannel.[ch].
3816 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Added one new argument <user mode> to the WHOIS command reply
3819 to return the mode of the user in SILC. Updated the protocol
3822 Implemented it to the server and client.
3824 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Fixed the mode printing on the user interface on joining.
3827 Affected file silc/client_ops.c.
3829 * Implemented the UMODE command and user modes in general to the
3830 client library and to the user interface.
3832 * Implemented the UMODE command to the server.
3834 * The server now sends UNKNOWN_COMMAND error status if client sends
3835 unknown command. Affected file silcd/command.c.
3837 * All server commands now handle the command identifier the right
3838 way when sending the command reply to the client. The client can
3839 use to identify the command replies with the identifier.
3841 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added silc_server_get_client_route to resolve the route to
3844 the client indicated by the client ID. Affected file is
3847 * Added silc_server_relay_packet as general function to relay
3848 packet to arbitrary destination. This deprecates functions
3849 like _send_private_message_key, _relay_notify etc. Affected
3850 file is silcd/packet_send.[ch].
3852 Removed silc_server_send_key_agreement,
3853 silc_server_send_private_message_key and
3854 silc_server_packet_relay_notify functions from the file
3855 silcd/packet_send.[ch].
3859 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3860 server. Affected file silcd/packet_receive.[ch].
3862 * Implemented the KILL command to the client. Implemented the
3863 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3864 Affected files lib/silcclient/command[_reply].c and
3865 lib/silcclient/client_notify.c. Implemented the KILL notify
3866 printing in the user inteface.
3868 * Fixed a lot silc_parse_nick memory leaks from the client
3869 library in the file lib/silcclient/command.c.
3871 * Changed the silc_server_send_notify_on_channels's `sender'
3872 argument from SilcSocketConnection to SilcClientEntry to
3873 check the sender as entry and not as connection object and not
3874 to send to the client provided as argument. The affected file
3875 is silcd/packet_send.[ch].
3877 * The notify packets that are destined directly to the client used
3878 to not to be processed by the server. Now changed that and the
3879 server processes all notify packets. After relaying the packet
3880 to the client the notify packet is processed in the server.
3882 * The silc_server_free_client_data now checks whether there is
3883 pending outgoing traffic for the client and purges the data to
3884 the network before removing the client entry.
3886 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3889 an client is killed from the SILC Network. Updated the protocol
3892 Added new function silc_server_send_notify_killed to the
3893 silcd/packet_send.[ch].
3895 * Added function silc_server_packet_relay_notify to relay notify
3896 packets that are destined directly to a client. In this case
3897 the server does not process the notify packets but merely relays
3898 it to the client. Affected file silcd/packet_send.[ch].
3900 Added also silc_server_packet_process_relay_notify to check
3901 whereto relay the notify. Affected file is
3902 silcd/packet_receive.[ch].
3904 * Implemented the KILL command to the server.
3908 * Added the backup schema desgined last fall to the protocol
3909 specs for everyone to see. The specification is in the
3910 *-spec-xx.txt draft and the packet type definitions for the
3911 backup routers is in *-pp-xx.txt draft. Thusly, added also
3912 new packet type SILC_PACKET_CELL_ROUTERS.
3914 * A big security problem in the implementation discovered. The
3915 signoff of an client did not cause new channel key generation
3916 which it of course should've done. The channel keys must be
3917 always re-generated when client leaves (or signoffs) the channel.
3918 The silc_server_remove_from_channels funtion now handles
3919 the channel key re-generation.
3921 * Added `sender' argument to the silc_server_send_notify_on_channels
3922 to not to send the client provided as argument. Affected file
3923 silcd/packet_send.[ch].
3925 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Implemented OPER and SILCOPER commands into the server and
3930 * Added silc_auth_verify and silc_auth_verify_data to verify
3931 the authentication directly from the authentication payload.
3932 It supports verifying both passphrase and public key based
3933 authentication. Affected file lib/silccore/silcauth.[ch].
3935 * Added `hash' field to the SilcIDListData structure. It is the
3936 hash negotiated in the SKE protocol. Affected file is
3939 * Slight redesigning of the SilcAuthPayload handling routines.
3940 Do not send SilcPKCS but SilcPublicKey as argument.
3942 * Implemented the public key authentication support to the
3943 serverconfig. The public key is loaded from the provided path
3944 and saved as authentication data to void * pointer. Thus,
3945 changed the unsigned char *auth_data to void *auth_data;
3947 * Fixed SHUTDOWN command to send the reply before the server
3948 is shutdown. :) Affected file silcd/command.c.
3950 * Fixed fatal bug in CONNECT command. The hostname was invalid
3951 memory and server crashed. Affected file silcd/command.c.
3953 * Fixed fatal bug in CLOSE command. The server_entry became
3954 invalid but was referenced later in the command. Affected file
3957 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Fixed fatal bug in failure packet handling. Server ignored
3960 the failure and thus crashed when it came.
3964 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3967 that the command may be executed only once in (about) 2 seconds.
3968 The old SILC_CF_LAG flag is same but allows command bursts up
3969 to five before limiting.
3971 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3972 server code. Various commands now includes the CF_LAG_STRICT
3973 flag to disallow any kind of miss-use of the command.
3975 * Fixed the silc_buffer_unformat to not to allocate any data
3976 if the length of the data is zero. It used to allocate the
3977 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3979 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Changed the format of AdminConnection configuration section
3982 in the server. Added username of the admin to the format.
3983 Affected files silcd/serverconfig.[ch].
3985 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3986 to return admin configuration data by host, username and/or
3989 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Implemented WHOWAS command to the server. Added the functions:
3993 silc_server_command_whowas_parse,
3994 silc_server_command_whowas_send_reply,
3995 silc_server_command_whowas_from_client and
3996 silc_server_command_whowas_from_server
3998 * Added <Client ID> argument to the WHOWAS command reply. Updated
3999 the protocol specs accordingly.
4001 * Implemented WHOWAS command and command_reply to the client
4004 Implemented the WHOWAS printing on the user interface.
4006 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Added new argument to the WHOWAS command reply, the real name.
4009 It is an optional argument. Updated the protocol specs.
4011 * Added SilcIDCacheDestructor callback that is registered when
4012 the SilcIDCache is allocated. The callback is called when
4013 an cache entry in the ID Cache expires, or is purged from the
4014 cache. Added into lib/silccore/idcache.[ch].
4016 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4017 to destruct the client entries when the cache entry expires.
4018 Other ID Cache's in server and in the client library ignores
4021 * If the ID Cache entry's `expire' field is zero then the entry
4022 never expires. Added boolean `expire' argument to the
4023 silc_idcache_add function in the lib/silccore/idcache.[ch].
4024 If it is TRUE the default expiry value is used.
4026 * Added silc_server_free_client_data_timeout that is registered
4027 when client disconnects. By default for 5 minutes we preserve
4028 the client entry for history - for WHOWAS command.
4030 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Added support to the server to enforce that commands are not
4033 executed more than once in 2 seconds. If server receives
4034 commands from client more frequently, timeout is registered
4035 to process the commands. Affected file silcd/command.c.
4036 Added new function silc_server_command_process_timeout.
4038 * Changed NICK_NOTIFY handling in client library to check that
4039 if the client's nickname was changed, so there is no need to
4040 resolve anything from the server.
4042 * Removed error printing from the WHOIS and IDENTIFY commands.
4043 If error occurs then it is ignored silently in the client library.
4044 The application, however, may map the received error to
4045 human readable error string. The application currently maps
4046 the NO_SUCH_NICKNAME error to string.
4048 * Made the command status message public to the application. Moved
4049 them from lib/silcclient/command_reply.c to
4050 lib/silcclient/command_reply.h. The application can map the
4051 received command status to the string with the
4052 silc_client_command_status_message function.
4054 * Added check to the server to check that client's ID is same
4055 as the Source ID in the packet the client sent. They must
4058 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Added dist-bzip hook to the Makefile.am to make bzip2
4061 compressed distributions.
4063 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Server now enforces the maximum length for the nickname and
4066 the channel as protocol specification dictates. 128 bytes for
4067 nickname and 256 bytes for channel name.
4069 * Moved the WHOIS printing to the application. The client libary
4070 does not print out the WHOIS information anymore, the application
4071 must do it. Renamed silc_client_command_reply_whois_print to
4072 the silc_client_command_reply_whois_save.
4074 The client's idle time is also sent to the application now, and
4075 the idle is shown on screen.
4077 * Added silc_client_command_reply_identify_save to save the
4078 received IDENTIFY entries.
4080 * Do not check for channel private keys in message sending and
4081 reception if the channel does not have the PRIVKEY mode set.
4082 Affected file lib/silclient/client_channel.c.
4084 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4087 just surfaced after chaning the JOIN procedure.
4089 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Added silc_client_get_clients_by_list to get client entries
4092 from Client ID list, that is returned for example by JOIN
4093 and USERS command replies. The application should use this
4094 function for example when JOIN command reply is received to
4095 resolve the clients already on the channel (library does not
4096 do that anymore as USERS command reply is not used in the JOIN
4097 procedure anymore). Affected files lib/silcclient/silcapi.h and
4098 lib/silcclient/idlist.c.
4100 * JOIN command reply and USERS command reply returns now SilcBuffer
4101 pointers instead of unsigned char pointers when returning
4102 the client list and mode list.
4104 * Added <Client ID> argument to the JOIN command reply, mainly
4105 for the server to identify for which client the command was
4106 originally sent. Updated protocol specs accordingly.
4108 * Added SilcDlist private_key pointer to the SilcChannelEntry
4109 in the client to support the channel private keys. Affected
4110 file is lib/silcclient/idlist.h.
4112 * Added SilcChannelPrivateKey argument to the function
4113 silc_client_send_channel_message so that application can choose
4114 to use specific private ke if it wants to. If it is not provided,
4115 the normal channel key is used, unless private keys are set.
4116 In this case the first (key that was added first) is used
4117 as the encryption key.
4119 * Implemented the support for channel private key handling.
4120 Implemented the following functions:
4122 silc_client_add_channel_private_key,
4123 silc_client_del_channel_private_keys,
4124 silc_client_del_channel_private_key,
4125 silc_client_list_channel_private_keys and
4126 silc_client_free_channel_private_keys
4128 Affected file lib/silcclient/client_channel.c.
4130 * Added the support for the private keys in the channel message
4131 sending and encryption and in the message reception and
4132 decryption. Affected funtions are
4133 silc_client_send_channel_message and silc_client_channel_message.
4135 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added SKE's key verify callback to the client library's
4138 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4140 * Removed the statement that server (or router) must send USERS
4141 command reply when joining to the channel so that the client
4142 knows who are on the channel. Instead, the client list and
4143 client's mode list is now sent in the JOIN command reply to the
4144 client who joined channel. This is better solution.
4146 * Added function silc_server_get_users_on_channel and function
4147 silc_server_save_users_on_channel to the silcd/server.[ch].
4149 * Removed function silc_server_command_send_users from the
4152 * Do not show topic on the client library anymore. The topic is
4153 sent in the command reply notify to the application and the
4154 application must show the topic now.
4156 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Added client searching by nickname hash into the IDENTIFY and
4159 WHOIS commands in the server as they were clearly missing from
4160 them. Affected file is silcd/command.c.
4162 * Fixed a bug in private message receiving in the client library.
4163 The remote ID was freed and it wasn't supposed, now it is
4166 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Minor fix to the channel payload; allocate the data area, as it
4169 needs to be of specific length.
4171 * If the key agreement port is zero then the operating
4172 system will define the bound port. Affected files are
4173 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4175 * Added new function silc_channel_payload_decrypt into the file
4176 lib/silccore/silcchannel.[ch].
4178 * Moved the channel message etc, check from silc_packet_decrypt
4179 to applications. The library calls now a generic
4180 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4181 when the packet is either normal or special. This was done to
4182 allow more wide range of checking that was not allowed when
4183 the code was in library. Now applications can do virtually any
4184 checks to the packet and return to the library the decision how
4185 the packet should be processed. Affected files are
4186 lib/silccore/silcpacket.[ch].
4188 Added silc_server_packet_decrypt_check to the server and
4189 silc_client_packet_decrypt_check to the client library.
4191 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4192 to send with specified source and destination information.
4194 * Channel message delivery between routers was broken after the
4195 channel key distribution was fixed earlier. The channel key
4196 was used be to distributed to other routers as well which is not
4197 allowed by the protocol. Now this is fixed and channel keys
4198 really are cell specific and the channel message delivery between
4199 routers comply with the protocol specification.
4201 * Fixed various commands in server to check also the global list
4202 for the channel entry and not just the local list. The affected
4203 file silcd/command.c.
4205 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added assert()s to buffer formatting and unformatting routines
4208 to assert (if --enable-debug) when error occurs. Affected
4209 file: lib/silcutil/silcbuffmt.c.
4211 * Changed to auto-reconnect to check whether the remote host is
4212 router and register the re-connect timeout if it is. It used
4213 to check that whether we are normal server, but router must do
4214 auto-reconnect with another router as well. Affected file
4217 * Removed the [<key len>] option from CMODE command as the cipher
4218 name decides the key length, nowadays. See the defined ciphers
4219 from the protocol specification.
4221 * Added [<hmac>] option to the CMODE command to define the HMAC
4222 for the channel. Added SILC_CMODE_HMAC channel mode.
4224 * Added [<hmac>] option for the JOIN command so that user can
4225 select which HMAC is used to compute the MACs of the channel
4228 * Added Hmac field to the Channel Message Payload. The integrity
4229 of plaintext channel messages are now protected by computing
4230 MAC of the message and attaching the MAC to the payload. The
4231 MAC is encrypted. Now, it is clear that this causes some
4232 overhead to the size of the packet but rationale for this is that
4233 now the receiver can verify whether the channel message decrypted
4234 correctly and also when private keys are set for the channel the
4235 receiver can decrypt the packet with several keys and check from
4236 the MAC which key decrypted the message correctly.
4238 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4239 lib/silccrypt/silccipher.[ch].
4241 * Added silc_hash_len to return the digest length into the
4242 lib/silcrypt/silchash.[ch].
4244 * Rewrote parts of Silc Channel Payload interface in the
4245 lib/silccore/silcchannel.[ch]. The encode function now also
4246 encrypts the packet and parse function decrypts it.
4248 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Fixed a minor formatting bug in the SKE's key material processing.
4251 It actually might have processed the keys wrong way resulting
4254 * Redefined the mandatory HMAC algorithms and added new algorithms.
4255 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4256 and hmac-md5 truncated to 96 bits. The mandatory is now
4257 hmac-sha1-96. Rest are optional (including the one that used
4258 to be mandatory). Rationale for this is that the truncated HMAC
4259 length is sufficient from security point of view and can actually
4260 make the attack against the HMAC harder. Also, the truncated
4261 HMAC causes less overhead to the packets. See the RFC2104 for
4264 * Added new [hmac] configuration section. The SKE used to use
4265 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4266 is of course wrong. The official names that must be proposed in
4267 the SKE are the ones defined in the protocol specification
4268 (hmac-sha1-96 for example). The user can configure any hmac
4269 using any hash function configured in the [hash] section. At
4270 least, the mandatory must be configured.
4272 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4274 * Added HMAC list to the SKE proposal list. It has now both
4275 hash algorithm list and HMAC list. This makes the protocol
4276 incompatible with previous versions. The SKE now seems to work
4277 the way it is supposed to work, for the first time actually.
4279 * Defined plain Hash algorithms to the protocol specification.
4282 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Implemented support for key agreement packets into the server.
4285 Added functions silc_server_key_agreement and
4286 silc_server_send_key_agreement. Other than these functions,
4287 server has nothing to do with this packet.
4289 * Added support for private message key packets into the server.
4290 Added functions silc_server_private_message_key and
4291 silc_server_send_private_message_key.
4295 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4296 called in the protocol's final callback instead in the END
4297 protocol state. This makes a little more sense and in the same
4298 time in client we can use the same protocol routines for normal
4299 key exchange and to key agreement packet handling as well.
4301 * Added to both client's and server's KE protocol context the
4302 SilcSKEKeyMaterial pointer to save the key material. We will
4303 bring the key material to the protocol's final callback by doing
4304 this. The final callback must free the key material.
4306 * Added SKE's packet_send callback into client's KE protocol
4307 context so that the caller can choose what packet sending function
4308 is used. This way we can use different packet sending when
4309 doing normal SKE when doing key agreement packet handling (in
4310 the key agreement packet handling we do not want to encrypt
4313 * Implemented the responder side of the key agreement routines
4314 in the client. The client can now bind to specified port and
4315 accept incoming key negotiation. The key material is passed
4316 to the application after the protocol is over.
4318 * Implemented the processing of incoming Key Agreement packet
4319 in the client. Added function silc_client_key_agreement to
4322 * Implemented the intiator side of the key agreement routines
4323 in the client. The client can now initiate key agreement with
4324 another remote client. The key material is passed to the
4325 application after the protocol is over.
4327 * Created client_keyagr.c to include all the key agreement
4330 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4331 SILC_TASK_CALLBACK except that it is not static.
4333 * Created client_notify.c and moved the Notify packet handling
4334 from the client.[ch] into that file.
4336 * Created client_prvmsg.c and moved all private message and
4337 private message key routines from the client.[ch] into that file.
4339 * Create client_channel.c and moved all channel message and
4340 channel private key routines from the client.[ch] into that file.
4342 * Changed silc_client_get_client_by_id_resolve to resolve with
4343 WHOIS command instead of IDENTIFY command, in the file
4344 lib/silclient/idlist.c.
4346 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Implemented the SKE's responder side to the Client library.
4350 * When FAILURE is received to the protocol do not trust it
4351 blindly. Register a timeout to wait whether the remote closes
4352 the connection as it should do it, only after that process the
4353 actual failure. This was changed to both client and server.
4355 * Added client_internal.h to include some of the structures
4356 there instead of client.h in lib/silcclient/.
4358 * Added function silc_task_unregister_by_callback to unregister
4359 timeouts by the callback function.
4361 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Some "Incomplete WHOIS info" errors has been appearing on the
4364 log files. Took away the entry->userinfo check from WHOIS
4365 reply sending. The entry->userinfo is now " " if client did not
4366 provide one. I thought this was fixed earlier but something
4367 is wrong still. Let's see if the error still appears.
4369 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Fixed a minor bug in the login when the channel key is
4372 re-generated in the server. It used to generate the key in
4373 wrong order and thus caused problems in the channel traffic.
4375 * Fixed a minor bug in channel key distsribution after
4376 KICK command. The key was not sent to the router even though
4379 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Added silc_ske_process_key_material_data as generic routine
4382 to process any key material as the SILC protocol dictates. The
4383 function is used by the actual SKE library but can be used by
4384 applications as well. This relates to the private message keys
4385 and the channel private keys since they must be processed the
4386 same way the normal SILC session keys. The protocol dictates
4387 this. Affected files: lib/silcske/silcske.[ch].
4389 Added also silc_ske_free_key_material to free the
4390 SilcSKEKeyMaterial structure.
4392 * Defined silc_cipher_set_key function to set the key for
4393 cipher without using the object's method function. The affected
4394 files: lib/silccrypt/silccipher.[ch].
4396 * Implemented silc silc_client_add_private_message_key,
4397 silc_client_add_private_message_key_ske,
4398 silc_client_del_private_message_key,
4399 silc_client_list_private_message_keys and
4400 silc_client_free_private_message_keys functions in the
4403 Added functions silc_client_send_private_message_key to send
4404 the Private Message Key payload and silc_client_private_message_key
4405 to handle incoming Private Message Key payload.
4407 * Added Cipher field to the Private Message Key payload to set
4408 the cipher to be used. If ignored, the default cipher defined
4409 in the SILC protocol (aes-256-cbc) is used.
4411 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Removed lib/silcclient/ops.h file.
4415 Redefined parts of the SILC Client Library API. Created new
4416 file silcapi.h that deprecates the ops.h file and defines the
4417 published Client Library API. Defined also private message key
4418 API and channel private key API into the file.
4420 This is the file that the application must include from the
4421 SILC Client Library. Other files need not be included by
4422 the application anymore.
4424 * Added new key_agreement client operation callback and also
4425 defined the Key Agreement library API for the application.
4427 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4430 is used by clients to request key negotiation between another
4431 client in the SILC network. If the negotiation is started it
4432 is performed using the SKE protocol. The result of the
4433 negotiation, the secret key material, can be used for example
4434 as private message key.
4436 Implemented the Key Agreement payload into the files
4437 lib/silccore/silauth.[ch].
4439 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Redefined ciphers for the SILC protocol. Added some new ciphers
4442 and defined the key lengths for the algorithms. Changed the
4443 code accordingly. The default key length is now 256 bits.
4445 * Fixed SKE key distribution function silc_ske_process_key_material
4446 when the key length is more than 128 bits. The default key
4447 length in SILC is now 256 bits.
4449 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4450 to indicate unsupported algorithm.
4452 * Renamed rijndael.c to aes.c and all functions as well.
4454 * Fixed a long standing channel key setting bug in client library.
4455 Weird that it has never surfaced before.
4457 * Fixed bug in channel deletion. If the entire channel is removed
4458 then it must also delete the references of the channel entry
4459 from the client's channel list as the client's channel entry and
4460 the channel's client entry share same memory.
4462 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Implemented CONNECT and SHUTDOWN commands in the client.
4466 * Implemented CLOSE command to the client.
4468 * Added the function silc_idlist_find_server_by_name into the
4469 files silcd/idlist.[ch].
4471 Added the function silc_idlist_find_server_by_conn into the
4472 files silcd/idlist.[ch].
4474 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * DIE command was renamed to SHUTDOWN. Updated the both code
4479 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4480 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4482 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4485 * Added function silc_server_create_connection function to create
4486 connection to remote router. My server implementation actually
4487 does not allow router to connect to normal server (it expects
4488 that normal server always initiates the connection to the router)
4489 so the CONNECT command is only good for connecting to another
4492 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4495 or some other client was kicked from the channel.
4497 Implemented the handling of the notify type to both client
4500 Implemented silc_server_send_notify_kicked to send the KICKED
4501 notify. It is used to send it to the server's primary router.
4503 * Implemented the KICK command into server and client.
4505 * Added `query' argument to the silc_idlist_get_client function
4506 to indicate whether to query the client from server or not if
4509 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4510 to indicate that the client is not channel founder.
4514 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Removed the rng context from SilcPacketContext structure and
4517 changed that the packet routine uses the Global RNG API.
4519 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added support for quit message that client can "leave" on the
4522 channel when it quits the SILC. It is ditributed inside the
4523 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4525 Added silc_server_free_client_data that will take the
4526 signoff message as argument.
4528 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4530 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Updated parts of the protocol specification to keep it up
4535 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4538 payloads in one packet.
4540 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4541 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4542 use now the new List flag.
4544 * Also deprecated the following packet types: REPLACE_ID,
4545 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4547 * Added list support for Notify packet in server.
4549 * Added silc_server_send_notify_channel_change to send the
4550 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4551 the silc_server_send_replace_id.
4553 * Added silc_server_send_notify_nick_change to send the
4554 NICK_CHANGE notify type. Deprecates the function
4555 silc_server_send_replace_id.
4557 * Added silc_server_send_notify_join to send the JOIN notify type.
4558 Deprecates the function silc_server_send_new_channel_user.
4560 * Added silc_server_send_notify_leave to send LEAVE notify type.
4561 Deprecates the function silc_server_send_remove_channel_user.
4563 * Added silc_server_send_notify_cmode and
4564 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4565 types. Deprecates the silc_server_send_set_mode function.
4567 * Added SERVER_SIGNOFF notify type to indicate that server has
4568 quit. This means that all clients on the channel from that
4569 server will drop. This can be also used when netsplit happens.
4571 Deprecated REMOVE_ID packet type since it is not needed anymore
4574 Added silc_server_send_notify_server_signoff to send the
4575 SERVER_SIGNOFF notify type. Deprecates the function
4576 silc_server_send_remove_id.
4578 Added also silc_server_send_notify_signoff to send the
4579 SIGNOFF notify type.
4581 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4582 SILC protocol from this day on. Changed the protocol
4583 specification as well.
4585 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4586 notify type. It is used between routers to notify about
4587 topic changes on a channel.
4589 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4592 * Partly updated the protocol specification to comply with the
4593 changes now made. It is still though a bit outdated.
4595 * The JOIN notify type now takes one extra argument <Channel ID>.
4596 The packet used to be destined to the channel but now the
4597 JOIN type may be sent as list thus it is impossible to
4598 destine it to any specific channel. By adding this argument
4599 it is again possible.
4601 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Added CREDITS file. The CHANGES and CREDITS file will appear
4604 in the distribution as well.
4606 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4609 types in the server's silcd/packet_receive.c.
4611 * Implemented CMODE and CUMODE to work in router environment.
4613 * Fixed minor encoding and decoding buglet from the
4614 lib/silccore/silcmode.c.
4616 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4619 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4621 * Changed all SilcConfigServer* and silc_config_server* to
4622 SilcServerConfig* and silc_server_config*, respectively.
4625 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Associated the ID (client or server ID) to the Authentication
4628 Payload to avoid any possibility of forging. Updated the
4629 protocol specification and the code accordingly.
4631 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * The RSA key length is now save to the RsaKey context in the
4634 key generation process in lib/silccrypt/rsa.c. The key length
4635 is now used to figure out the maximum size of the block allowed
4636 to be encrypted/signed.
4638 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4639 is equivalent to the silc_mp_mp2bin but does not allocate any
4642 * Changed silc_mp_mp2bin API to take length argument. If it is
4643 non-zero then the buffer is allocated that large. If zero, then
4644 the size is approximated using silc_mp_sizeinbase, which however
4647 * Created Global RNG API which is global RNG that application can
4648 initialize. After initializing, any routine anywhere in the
4649 code (including library) can use RNG without allocating a new
4650 RNG object. This was done to allow this sort of use of the
4651 RNG in code that has no chance to allocate RNG object. All
4652 applications currently allocate this and many routines in the
4653 library use this. Affected file lib/silccrypt/silcrng.[ch].
4655 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4656 it to use the Global RNG API.
4658 * Defined Authentication Payload into protocol specification that
4659 is used during SILC session to authenticate entities. It is
4660 used for example by client to authenticate itself to the server
4661 to obtain server operator privileges.
4663 Implemented this payload into the lib/silccore/silcauth.[ch].
4664 Implemented also routines for public key based authentication
4665 as the new protocol specification dictates.
4667 Moved definitions of different authentication methods from
4668 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4670 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4671 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4672 silc_pkcs_verify_with_hash functions into the file
4673 lib/silccrypt/silcpkcs.[ch].
4675 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * The client entry's userinfo pointer must be always valid.
4678 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4679 will fail since it requires the userinfo. Now, the userinfo
4680 is allocated as "" if actual userinfo does not exist. Actually,
4681 it must exist and it is totally Ok to drop client connections
4682 that does not announce the userinfo. However, we will make
4683 this workaround for now.
4685 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4686 to return the remote port by socket.
4688 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4691 SILC_SERVER_PENDING_EXEC and added an new macro
4692 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4693 data or when error occurs while processing the pending command.
4695 Added new argument `destructor' into silc_server_command_pending
4696 and to the SilcServerCommandPending object. This destructor is
4697 now called after calling the pending callback or if error occurs
4698 immediately. If error occurs the actual pending callback won't
4699 be called at all - only the destructor. The destructor may be
4700 NULL if destructor is not needed.
4702 All this applies for client library code as well. Similar
4703 changes were made there as well for the pending commands.
4705 In the client, the application must now allocate the
4706 SilcClientCommandContext with the silc_client_command_alloc
4709 * Added reference counter to the SilcServerCommandContext. Added
4710 function silc_server_command_alloc and silc_server_command_dup
4713 Same type of functions added to the client library for the same
4716 * Removed the cmd_ident from IDListData away since it is now
4717 global for all connections. It is the command identifier used
4718 in command sending and with pending commands. The affected file
4721 * Added reference counter to the SilcSocketConnection objecet to
4722 indicate the usage count of the object. The object won't be
4723 freed untill the reference counter hits zero. Currently only
4724 server uses this, and client ignores it. The client must be
4725 set to use this too later. The affected files are
4726 lib/silccore/silcsockconn.[ch]. Added also the function
4727 silc_socket_dup to increase the reference counter.
4729 This was mainly added because it is possible that the socket
4730 is removed underneath of pending command or other async
4731 operation. Now it won't be free'd and proper DISCONNECTING
4732 flags, etc. can be set to avoid sending data to connection that
4733 is not valid anymore.
4735 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4736 the connection. After that it sets SILC_SET_DISCONNECTED.
4737 It is, however, possible that the socket data is not still freed.
4738 The silc_server_packet_process now checks that data is not
4739 read or written to connection that is DISCONNECTED. The socket
4740 get's freed when the reference counter hits zero.
4742 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Changed the client operation API: channel_message operation's
4745 `sender' is now the client entry of the sender, not the nickname
4746 and the `channel' is the channel entry, not the channel name.
4748 In the private_message operation the `sender' is now also the
4749 client entry of the sender not the nickname.
4751 Affected file is lib/silcclient/ops.h and all applications
4752 using the client operations.
4754 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Moved the calling of ops->connect() from connect_to_server_final
4757 into receive_new_id functin since that is the point when the
4758 client is actually allowed to send traffic to network. The
4759 affected file is lib/silcclient/client.c.
4761 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4764 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4765 (if needs broadcasting) instead of broadcasting the packets one
4766 by one which would make a burst in the network traffic.
4768 * Added `broadcast' argument to the functions in silcd/server.[ch]
4769 silc_server_create_new_channel[_with_id] to indicate whether
4770 to send New Channel packet to primary router.
4772 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added new function into the silcd/server.[ch] files:
4775 silc_server_create_new_channel_with_id to create new channel with
4776 already existing Channel ID.
4778 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4779 lib/silccore/silcpacket.h. This packet is used t send list of
4780 Set Mode payloads inside one packet. Server uses this to set
4781 the modes for the channels and clients on those channels, that it
4782 announced to the router when it connected to it. The protocol
4783 specification has been updated accordingly.
4785 * The silc_server_new_channel did not handle the packet coming
4786 from normal server as it normally does not send that. However,
4787 when it announces its channels it does send it. Implemented
4788 the support for that.
4790 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4791 into the file lib/silccore/id.h.
4793 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Fixed memory leaks in the functions silc_idlist_del_client,
4796 silc_idlist_del_channel and silc_idlist_del_server in the file
4797 silcd/idlist.c. All of those leaked like a sieve.
4799 * Fixed some small memory leaks in the client's function
4800 silc_client_notify_by_server.
4802 * Added functions into silcd/server.c: silc_server_announce_clients,
4803 silc_server_announce_channels and silc_server_announce_server.
4804 These functions are used by normal and router server to announce
4805 to its primary router about clients, channels and servers (when
4806 router) that we own. This is done after we've connected to the
4809 These functions effectively implements the following packet types:
4810 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4811 and SILC_PACKET_NEW_ID_LIST.
4813 * Added new functions into the silcd/packet_receive.[ch]:
4814 silc_server_new_id_list, silc_server_new_channel_list and
4815 silc_server_new_channel_user_list to handle the incoming
4816 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4818 * Added support of changing Channel ID in the function
4819 silc_server_replace_id. If the server that announces a channel
4820 to the router already exists in the router (with same name but
4821 with different Channel ID), router is responsible to send
4822 Replace ID packet to the server and force the server to change
4823 the Channel ID to the one router has.
4825 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4826 client that the Channel ID has been changed by the router. The
4827 normal server sends this to the client. Client must start using
4828 the new Channel ID as the channel's ID.
4830 Implemented handling of this new type into lib/silcclient/client.c
4831 into the function silc_client_notify_by_server.
4833 * Added new function silc_idlist_replace_channel_id into the files
4834 silcd/idlist.[ch] to replace the Channel ID.
4836 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Call silc_server_command_identify_check always when processing
4839 the IDENTIFY command in silcd/command.c
4841 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4844 send keepalive packets. The packet can be sent by clients,
4845 servers and routers.
4847 Added function silc_socket_set_heartbeat into the file
4848 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4849 If not set, the heartbeat is not performed. The actual
4850 heartbeat is implemented in the low level socket connection
4851 library. However, application is responsible of actually
4854 Added silc_server_send_heartbeat to send the actual heartbeat
4855 packet into silcd/packet_send.[ch]. Server now performs
4856 keepalive with all connections.
4858 * Added silc_task_get_first function into lib/silcutil/silctask.c
4859 to return the timeout task with shortest timeout. There was a bug
4860 in task unregistration that caused problems. TODO has been
4861 updated to include that task system must be rewritten.
4863 * The client library will now resolve the client information when
4864 receiving JOIN notify from server for client that we know but
4865 have incomplete information.
4867 * Rewrote parts of silc_server_remove_from_channels and
4868 silc_server_remove_from_one_channel as they did not remove the
4869 channel in some circumstances even though they should've.
4871 * Encryption problem encountered in server:
4873 The LEAVE command used to send the Channel Key packet to the
4874 router immediately after generating it. However, the code
4875 had earlier sent Remove Channel user packet but not immediately,
4876 ie. it was put to queue. The order of packets in the router
4877 was that Channel Key packet was first and Remove Channel User
4878 packet was second, even though they were encrypted in the
4879 reverse order. For this reason, MAC check failed. Now, this
4880 is fixed by not sending the Channel Key packet immediately but
4881 putting it to queue. However, this is more fundamental problem:
4882 packets that are in queue should actually not be encrypted
4883 because packets that are sent immediately gets encrypted
4884 actually with wrong IV (and thus MAC check fails). So, packets
4885 that are in queue should be encrypted when they are sent to
4886 the wire and not when they put to the queue.
4888 However, the problem is that the current system has not been
4889 designed to work that way. Instead, the packet is encrypted
4890 as soon as possible and left to the queue. The queue is then
4891 just purged into wire. There won't be any fixes for this
4892 any time soon. So, the current semantic for packet sending
4895 o If you send packet to remote host and do not force the send
4896 (the packet will be in queue) then all subsequent packets to the
4897 same remote host must also be put to the queue. Only after the
4898 queue has been purged is it safe again to force the packet
4901 o If you send all packets immediately then it safe to send
4902 any of subsequent packets through the queue, however, after
4903 the first packet is put to queue then any subsequent packets
4904 must also be put to the queue.
4906 Follow these rules and everything works fine.
4908 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Added new function silc_server_remove_clients_by_server to
4911 remove all client entries from ID list when the server connection
4912 is lost. In this case it is also important to invalidate all
4913 client entires as they hold the invalid server entry. This
4914 fixes fatal bug when server has lost connection and will reconnect
4917 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Made some sanity checks to silc_server_daemonise like to check
4920 whether the requested user and group actually exists.
4922 * Added sanity check to SKE's silc_ske_responder_finish to check
4923 that the public and private key actually is valid.
4925 * Invalidate the client's nickname when receiving Replace ID
4926 packet and the Client ID is being replaced. This means that the
4927 server will query the nickname if someone needs it (client)
4930 * Sort the ID Cache in client library when the ID Cache data
4931 has changed (needs sorting).
4933 * Do not allow for SILC client to create several connections to
4934 several servers. The client does not support windows right now
4935 and generating multiple connections causes weird behaviour.
4937 Irssi-silc client does support windows and can handle several
4938 connections without problems, see: www.irssi.org and SILC plugin.
4940 * Fixed some places where client was added to the IDList. The
4941 rule of thumb is following (in order to get everything right):
4942 If the client is directly connected local client then the
4943 `connection' argument must be set and `router' argument must be
4944 NULL to silc_idlist_add_client function. If the client is not
4945 directly connected client then the `router' argument must
4946 bet set and the `connection' argument must be NULL to the
4947 silc_idlist_add_client function.
4949 * The funtion silc_server_packet_send_local_channel actually did
4950 not check whether the client was locally connected or not. It
4951 does that now. Fixed a bug related to LEAVE command.
4953 * Fixed Remove Channel User payload parsing bug in server's
4954 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4956 * The server's silc_server_save_channel_key now checks also the
4957 global ID list for the channel as it might not be in the local
4958 list. Fixed a bug related to LEAVE command.
4960 * Is this the end of the [<unknown>] buglet that has been lurking
4961 around for a long time? A little for loop fix in server's
4962 silc_server_command_whois_parse that is used by both IDENTIFY
4963 and WHOIS command. At least, this was a clear bug and a cause
4964 of one type of [<unknown>] buglet.
4966 * WHOIS and IDENTIFY commands call the function
4967 silc_server_command_[whois/identify]_check function even if
4968 we are not router server.
4970 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Added --with-gmp configuration option. If set the GMP
4973 is always compiled in the SILC source tree. If not set then
4974 it is checked whether the system has the GMP3 installed. If
4975 it has then the GMP won't be compiled (the system's headers
4976 and library is used), if it doesn't have it then the GMP is
4977 compiled in the SILC source tree.
4979 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Changed RSA private exponent generation to what PKCS #1
4982 suggests. We try to find the smallest possible d by doing
4983 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4984 not security fix but optimization.
4986 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Added new config entry [Identity] to fork the server and run
4989 it as specific user and group. A patch from Bostik.
4991 * Imported Dotconf configuration library into lib/dotconf.
4992 This will be used to create the SILC configuration files later.
4993 It will appear in the distsribution after this commit.
4995 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * A big code auditing weekend happening. Auditing code for
4998 obvious mistakes, bugs and errors. Also, removing any code
5001 Removed files for being obsolete:
5003 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5004 inline in the file lib/silcutil/silcbuffer.h)
5006 o lib/silcutil/silcbufutil.c (the header has inline versions)
5008 Changed code to fix possible error conditions:
5010 o The buffer formatting routines now check that the destination
5011 buffer really has enough space to add the data. This applies for
5012 both buffer formatting and unformatting
5013 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5014 unformatting was changed to accomodate following rules:
5015 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5016 sent to the function while XXX_*STRING will not allocate or copy
5017 the data into the buffer. Instead it sets the pointer from the
5018 buffer into the pointer sent as argument (XXX_*STRING used to
5019 require that the pointer must be allocated already). This change
5020 makes this whole thing a bit more consistent and more optimized
5021 (note that the data returned in the unformatting with XXX_*STRING
5022 must not be freed now). The routines return now -1 on error.
5024 o Tried to find all code that use buffer_format and buffer_unformat
5025 and added return value checking to prevent formatting and
5026 especially unformatting errors and possible subsequent fatal
5029 o Changed ske->x and ske->KEY to mallocated pointers in
5030 lib/silcske/silcske.h. Fixed possible data and memory leak.
5032 o Added return value checking to all *_parse* functions. Fixed
5033 many memory leaks as well.
5035 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5036 so that buffer overflows would not happen. All code now also
5037 checks the return value as it can fail.
5039 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Added reconnection support to server if the normal server looses
5042 its connection to the router (for example if router is rebooted).
5043 The server performs normal reconnection strategy implemented
5044 to the server. Affected file silcd/server.c.
5046 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added new packet type SILC_PACKET_SET_MODE that is used to
5049 distribute the information about changed modes (for clients,
5050 channels and clients channel modes) to all routers in the
5051 network. Updated the protocol specification accordingly.
5053 Added functions into silcd/packet_send.c and
5054 silcd/packet_receive.c: silc_server_send_set_mode,
5055 silc_server_set_mode.
5057 Added new files silcmode.[ch] into lib/silccore that implements
5058 the encoding and decoding of Set Mode Payload. Added new type
5059 SilcSetModePayload. Moved the definitions of different modes
5060 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5062 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Oops, a little mistake in server's connection authentication
5065 protocol. The protocol is not ended with FAILURE but with
5066 SUCCESS if the authentication is Ok. :) Affected file is
5069 * Implemented NICK_CHANGE notify handling in server in the file
5070 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5071 the local clients on the channel. After the changing nickname
5072 in router environment snhould work and the [<unknown>] nickname
5073 should appear no more.
5075 The silc_server_replace_id function that receives the Replace ID
5076 payload now sends the NICK_CHANGE notify type also in the file
5077 silcd/packet_receive.c
5079 * Changed WHOIS and IDENTIFY command to support the maximum amount
5080 of arguments defined in protocol specs (3328 arguments). This
5081 fixed a bug that caused problems when there were more than three
5084 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Added extra parameter, command identifier, to the
5087 silc_client_send_command so that explicit command identifier
5090 Changed that ID list routines uses specific command identifier
5091 when sending WHOIS/IDENTIFY requests to the server so that they
5092 can be identified when the reply comes back.
5094 Affected files lib/silcclient/command.[ch],
5095 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5097 * Added `sender' argument to silc_server_packet_send_to_channel
5098 to indicaet the sender who originally sent the packet to us
5099 that we are now re-sending. Ignored if NULL. Affected file
5100 silcd/packet_send.[ch].
5102 * Added some server statistics support in silcd/server_internal.h
5103 SilcServerStatistics structure and around the server code. Also
5104 send some nice statistics information when client is connecting
5107 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Fixed channel ID decoding in server's JOIN command reply in
5110 silcd/command_reply.c
5112 * Fixed braodcasting of replace ID payload to not to send it if
5113 we are standalone server in silcd/packet_receive.c.
5115 * Fixed all channel message sending routines to not to send
5116 packets to clients that has router set, since they are routed
5117 separately in the same function earlier. Affects file
5118 silcd/packet_send.c and all channel packet sending functions.
5120 * In USERS reply, res_argv[i] are not allocated, the table
5121 is allocated. Thus changed that free the table, not its
5124 * In server's whois_check and identify_check if the client is
5125 locally connected do not send any WHOIS commands - they are not
5128 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Fixed some minor bugs in client when sending WHOIS command. The
5131 arguments was in wrong order.
5133 * Removed statis function add_to_channel from server in
5134 silcd/command.c that was previously used with the joining but
5137 * Tested USERS command in router environment successfully with two
5138 routers, two servers and two clients.
5140 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Reorganized the USERS command and command reply in client library
5143 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5144 When the command is given by user we register a pending command
5145 callback that will reprocess the command after the reply has been
5146 received from the server. When reprocessing the packet we then
5147 display the information. Thus, the USERS information is displayed
5148 now in the command callback instead of in the command reply
5149 callback. The processing of the command is same as previously
5150 when server has sent the command reply in the JOINing process.
5152 * Added to USERS command in silcd/command_reply.c to join the client,
5153 we didn't use to know about, to the channel after we've created
5154 a client entry for it. Also, for clienet we did know already still
5155 check whether it is on the channel or not and add it if not.
5157 * Removed silc_server_command_join_notify as the function and its
5160 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Changed the client's pending command handling to the same as the
5163 server's pending command handling. It is also now possible to
5164 execute command reply functions from other command reply
5165 function as the function callbacks for commands and command
5166 replies are one and same. The pending commands are not static
5167 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5168 in client connection context. Thus, pending commands are server
5169 connection specific as it is convenient.
5171 Changed the function silc_client_command_pending and
5172 silc_client_command_pending_del and added new function
5173 silc_client_command_pending_check. Removed the
5174 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5177 * Added cmd_ident, current command identifier, to the client
5178 connection context in lib/silcclient/client.h to keep track on
5179 command identifiers used in command sending. Client's command reply
5180 function handling now supports the mandatory command identifiers.
5182 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5183 funtions in client to fully support pending command callbacks.
5185 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5186 as one of the arguments to the application in the command reply
5189 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5190 before first releasing SILC but came back. Now it is removed again
5191 and should come back nomore. The FORWARDED flag was used only
5192 by the JOINing procedure by forwarding the command packet to router.
5193 Now, the JOINing procedure has been changed to more generic (due
5194 to various router environment issues) and FORWARDED is not needed
5195 anymore for anything. The protocol specification is yet to be
5198 Now, removed silc_server_packet_forward from server and the flag
5199 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5201 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Renamed NAMES command to USERS command. The NAMES was named that
5204 due to historical reasons. Now it is renamed. Also, rewrote
5205 parts of the USERS command. The nickname list is not sent anymore
5206 by the server. Only Client ID and mode lists are sent in the USERS
5207 command. Changed this also to the protocol specification.
5209 The client now resolves the names and stuff after it receives
5210 the USERS list from the server when joining to the channel.
5212 * WHOIS and IDENTIFY commands has been changed to support multiple
5213 Client ID's per command. One can now search for multiple users
5214 in the network by sending only one WHOIS or IDENTIFY command.
5215 Changed the code and the protocol specifications.
5217 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5218 uses silc_server_command_whois_parse to parse the request. */
5220 * If normal server, do not parse the WHOIS and IDENTIFY requests
5221 before sending it to the router. Saves some time.
5223 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Fixed JOIN command on client library. Wrong number of arguments
5226 used to crash the client.
5228 * Added silc_server_channel_has_global function to check whether
5229 channel has global users or not.
5231 * Added silc_server_channel_has_local function to check whether channel
5232 has locally connected clients on the channel.
5234 * The silc_server_remove_from_one_channel now checks whether the
5235 channel has global users or not after given client was removed from
5236 the channel. It also checks whether the channel has local clients
5237 on the channel anymore. If it does not have then the channel entry
5238 is removed as it is not needed anymore.
5240 * The silc_server_notify now checks on JOIN notify whether the joining
5241 client is one of locally connected or global. If it is global then
5242 the channel has now global users on the channel and that is marked
5243 to the channel entry. Also, it now saves the global client to
5244 global list who is joining and JOINs it to the channel. This is
5245 for normal server, that is.
5247 Changed silc_server_send_notify_on_channel,
5248 silc_server_packet_relay_to_channel and
5249 silc_server_packet_send_to_channel check if we are normal server
5250 and client has router set (ie. global client) do not send the
5251 message to that client, as it is already routed to our router.
5253 * Implemented LEAVE notify type handling in silc_server_notify
5256 * Tested LEAVE command in router environment successfully. Tested
5257 with two routers, two servers and two clients.
5261 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5263 * Implemented SIGNOFF notify type handling in silc_server_notify
5266 * silc_server_remove_id now removes the client entry from all channels
5267 it has joined and thusly sends SIGNOFF notify type.
5269 * Rewrote the NAMES list generation in server by removing two excess
5270 loops. The lists are created now inside one loop.
5272 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * silc_server_remove_channel_user checks now also global list
5275 for channel and client.
5277 * silc_server_new_channel_user checks now both local and global
5278 list for channel and client. Fixed a bug in client id decoding.
5279 Used to decode wrong buffer.
5281 * silc_server_channel_message checks now both local and global
5282 list for channel entry.
5284 * Tested channel joining (hence JOIN) in router environment
5285 successfully. Tested with two routers, two servers and two
5288 * Tested channel message sending in router environment successfully.
5290 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Added silc_server_save_channel_key into server.[ch] to save the
5293 received channel key in Channel Key payload processing. It is
5294 also used in JOIN command reply handling.
5296 Equivalent function silc_client_save_channel_key added into
5297 client.[ch] into client library.
5299 * Changed JOIN command reply to send information whether the channel
5300 was created or not (is existing already) and the channel key
5301 payload. Changed protocol specs accordingly.
5303 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5304 the request was sent by ID and not by nickname. Crashed on
5307 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5310 now correctly save the received data.
5312 * silc_server_free_sock_user_data now notifies routers in the
5313 network about entities leaving the network.
5315 At the same time implemented functions silc_server_remove_id
5316 and silc_server_send_remove_id to receive and send REMOVE_ID
5317 packets. The packet is used to notify routers in the network
5318 about leaving entities. The ID removed will become invalid in
5321 * Added function silc_idlist_del_server into server. Removes and
5322 free's server entry from ID list.
5324 * silc_server_private_message function now checks, if we are router,
5325 that the destination ID really is valid ID, naturally.
5327 * In router when NEW_ID packet is received (for new client) the
5328 hash of the Client ID is saved in the ID Cache but the
5329 client->nickname is set to NULL, instead of putting the hash
5332 IDENTIFY command now also checks that client->nickname must be
5333 valid. If it is not if will request the data from the server who
5334 owns the client. Added new function
5335 silc_server_command_identify_check.
5337 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5338 to set the command to already allocated Command Payload.
5340 * Tested private message sending in router environment with two
5341 routers, two servers and two clients. Fixed minor bugs and now
5344 * Fixed segfault from client's NAMES command. Used to crash if
5347 * Forwarded packets must not be routed even if it is not destined
5348 to the receiver. Changed server code comply with this.
5350 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added `require_reverse_mapping' boolean value to ServerParams
5353 structure. If TRUE (not default) the server will require that
5354 the connecting host has fully qualified domain name.
5356 If the reverse mapping is not required and hostname could not be
5357 found the IP address is used as hostname.
5359 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Implemented version string checking to both client and server.
5362 The check is incomplete currently due to the abnormal version
5363 strings used in development version of SILC.
5365 * Changed all command functions in server to use the new
5368 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Changed char *data to unsigned char *data in ID Cache system to
5371 support binary data as ID Cache data. Changed code to support
5372 binary data in lib/silccore/idcache.c.
5374 * Renamed silc_server_packet_relay_command_reply to
5375 silc_server_command_reply as it is normal packet receiving
5376 function. Rewrote the function to accept command replys for
5377 servers and not only for clients.
5379 * Mark remote router always as registered server if we are connecting
5380 to it. Otherwise, commands sent by the router to us are ignored.
5382 * All ID List find routines now returns the ID Cache Entry pointer
5383 as well if requested.
5385 * WHOIS command works now in router environment, tested with two
5386 routers, two servers and two clients.
5388 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5389 in router environment (as it is almost equivalent to WHOIS) but
5390 hasn't been tested thoroughly. Added new functions:
5392 silc_server_command_identify_parse
5393 silc_server_command_identify_send_reply
5394 silc_server_command_identify_from_client
5395 silc_server_command_identify_from_server
5397 * Disabled route cache adding because adding two different ID's with
5398 same IP replaces the old cache entry thus giving wrong route.
5399 The entry->router->connection is always the fastest route anyway
5400 so route cache may not be needed. Of course, new routes maybe
5401 established after receiving the ID when the entry->router->connection
5402 might not be anymore the most optimal.
5404 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Add route cache for received ID for fast routing.
5408 * Added silc_server_packet_route to route received packet on router
5409 that is not destined to us.
5411 * Renamed silc_server_get_route to silc_server_route_get.
5413 * Added id_string and id_string_len fields into SilcServer to
5414 include encoded ServerID for fast comparing without excess
5415 encoding of the ID's.
5417 * Cleaned up WHOIS command on server side. Added following static
5420 silc_server_command_whois_parse
5421 silc_server_command_whois_check
5422 silc_server_command_whois_send_reply
5423 silc_server_command_whois_from_client
5424 silc_server_command_whois_from_server
5426 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5427 arguments in command replies. All command functions should be
5428 updated to use this macro.
5430 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Minor typo fixes on command reply handling on server.
5434 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Added silc_server_command_add_to_channel internal routine to add
5437 the client to the channel after router has created the channel and
5438 sent command reply to the server.
5440 * Added generic silc_server_send_command to send any command from
5443 * Use static buffer with ID rendering instead of duplicating data.
5445 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Fixed a channel user mode bug when joining to a channel server gave
5448 everybody channel founder rights, oops.
5450 * We mark ourselves as the router of the incoming server connection
5451 if we are router ourselves. This way we can check in some packet
5452 sending functions whether it is locally connected server. For
5453 incoming router connections we put NULL.
5455 * For router sending packets locally means now always sending the
5456 packet cell wide; to local clients and local servers. For normal
5457 server sending packet locally means sending it to only local
5460 * Fixed the JOIN command to really work in router environment. If the
5461 channel is created it is always created by the router. Router is
5462 also responsible of making the initial joining to the channel,
5463 sending JOIN notify to the sending server and distributing
5464 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5465 does not exist server doesn't do anything else but forward the
5466 command to the router which performs everything.
5468 * Added silc_server_send_channel_key function to send the Channel Key
5471 * Added silc_server_create_channel_key to create new channel key. The
5472 channel key is now re-generated everytime someone joins or leaves
5473 a channel, as protocol dictates. Note: channel->key_len is the
5476 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5479 packet_receive.[ch] to separate packet sending and receiving
5480 routines. The server.[ch] now includes everything else including
5481 actual packet processing (writing and reading data) and other
5484 Renamed silc_server_private_message_send_internal to
5485 silc_server_send_private_message. The routine is still though
5486 used only to relay private messages as server does not send
5487 private messages itself.
5489 Renamed silc_server_new_channel to silc_server_create_new_channel
5490 and added new function sicl_server_new_channel that handles the
5491 incoming New Channel packet. Added also new sending function
5492 silc_server_send_new_channel to send New Channel Payload.
5494 * Added new function silc_server_notify to process incoming notify
5495 packet to the server/router. Server may then relay the notify
5496 to clients if needed.
5498 * Added new function silc_server_new_channel_user to process incoming
5499 New Channel User packet. Router will redistribute the packet and
5500 send JOIN notify to its local clients and locally connected servers
5501 if needed. Normal server will send JOIN notify to its local client
5502 on same channel when received this packet. Added also corresponding
5503 sending function silc_server_send_new_channel_user to sent the
5506 * Added boolean route argument to send_notif_to_channel and
5507 packet_send_to_channel functions to attempt to route the packet
5508 if it is TRUE and send only locally if it is FALSE.
5510 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * silc_server_replace_id now broadcasts the received replace ID
5513 packet if it is not broadcast packet already. The router must
5514 broadcast to inform other routers about changed ID.
5516 * Added backpointer to server's router into SilcServer context in
5517 silcd/server_internal.h.
5519 * Fixed silc_server_packet_broadcast to send correct broadcast
5522 * The channel key is now distributed to the local client as soon
5523 as it is received from the router (in router environment) so that
5524 no other packet may be sent for the channel until client has
5527 * silc_server_remove_channel_user now broadcasts the received
5528 Remove Channel User packet if it is not broadcast packet already.
5529 The router must broadcast to inform other routers about removed
5532 * Added users field into SilcPacketContext that is a reference count
5533 of the context. One can increase the reference count by calling
5534 silc_packet_context_dup which is now changed to just increase the
5535 reference count instead of duplicating the data. The reference
5536 count is decresed by calling silc_packet_context_free that will
5537 free the data after the reference count hits zero.
5539 For now on the packet context and everything allocated into it
5540 (including the raw packet from network) must be freed by calling
5541 the new silc_packet_context_free function. Added also new function
5542 silc_packet_context_alloc that must be used now to allocate the
5543 context. This also means that if a routine is asynchronous from
5544 silc_[client/server]_packet_parse_type the packet context must
5545 be duplicated by calling silc_packet_context_dup. Otherwise it
5546 gets free'd after silc_[client/server]_packet_parse_type returns.
5547 Also, one must remember that if packet is duplicated then its
5548 reference count must be decresed by calling the free function as
5549 many times as it was duplicated.
5551 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5552 from both client and server.
5554 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Made joining to a channel working in router environment.
5558 * Cleaned up JOIN command on server side and create function
5559 silc_server_command_join_channel internal routine to make the
5562 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Changed silc_command_pending list to SilcDList. Also, added
5565 `ident' field to SilcServerCommandPending structure to identify
5566 the reply and to call correct callback.
5568 Added silc_server_command_pending_check function to replace the
5569 corresnponding macro. The silc_command_pending list is not
5572 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5573 to set identifier to previously allocated Command Payload. It
5574 is used to set identifier for command when resending Command
5577 * Added silc_command_payload_encode_payload to encode Command
5578 Payload buffer from SilcCommandPayload structure.
5580 * Added silc_argument_payload_encode_payload to encode Argument
5581 payload buffer from SilcArgumentPayload structure.
5583 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Changed WHOIS command to support router connection on server side.
5586 The whois request is always sent to router unless the server is
5587 standalone server. After server has received the reply from the
5588 router will it send the reply to the client.
5590 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5591 broadcast received broadcast packet. The function is used only
5592 by router. The broadcast packet is always sent to the router's
5595 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5596 render given ID to printable string, for log files for example.
5598 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Made basic router to router connections working. At least they
5601 can now connect to each other but nothing really works the way
5602 they are supposed - yet.
5604 * Added new initiator token to RouterConnection configuration
5605 file in silcd/serverconfig.[ch]. It is used to tell whether we
5606 are the initiator to the remote router or whether we'll expect
5607 the other end to connect.
5609 * Moved registering of listener task to silc_server_init, hence
5610 the server starts listenning as soon as it is run, even if it
5611 does not have connections to other routers. Let's see how well
5614 * Changed default connection retry timeouts for more suitable in
5617 * Removed cipher and such arguments from silc_idlist_add_client
5618 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5619 Added new function silc_idlist_add_data to add the keys and stuff
5622 * Added SilcIDListData structure and added it to SilcClientEntry
5623 and SilcServerEntry as their first field in the structure. This
5624 way we can explicitly cast the ID entries to the SilcIDListData
5625 structure and get common data for the entries. In past, we had
5626 to first check what type of connection it is and then cast it to
5627 correct ID entry type. Now, we can directly cast the opaque
5628 pointer to the SilcIDListData (no matter what ID entry it actually
5629 is) and get the data needed.
5631 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5634 in some circumstances even if threre were timeout tasks, though not
5635 IO tasks, but tasks anyway. Now fixed.
5637 * Defined SilcServerConnection structure to hold connection specific
5638 stuff about directly connected servers and routers. The definition
5639 is currently in silcd/server_internal.h. I thought about having
5640 a bit more important role fro this struct but for now it is used
5641 only when connecting to other server (or router actually).
5643 * Added connecting retry support in server when connecting to
5644 router(s). The retry feature implement exponential backoff
5645 algorithm. Also, added SilcServerParams structure to hold default
5646 parameters for server. For now, it include these retry settings
5647 and are hard coded. After server is moded to be as Silc Server
5648 Library this structure will be more important.
5650 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Changed client librarys channel->clients table to SilcList and
5653 changed code accordingly.
5655 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Changed client's channel table to SilcList and changed code
5658 accordingly. Also changed SilcChannelClientEntry to include back-
5659 pointer to the channel so that client entry can use that structure
5660 as list as well and we have fast cross-reference to the channel.
5661 This change dramatically decreased the complexity of channel
5662 handling with client entry and vice versa (removed one extra
5663 loop when searching for channel entry from many functions).
5665 * Changed server->sim from table to SilcDList and changed code
5668 * NAMES command can now be used from user interface. It will show
5669 the user list on the channel, neatly.
5671 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5672 Code now saves realname of the user if it becomes available.
5674 * Renamed configure.in to configure.in.pre and made ./prepare
5675 script to automatically add correct version string to
5676 configure.in which it creates from configure.in.pre.
5678 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * NAMES command reply now shows users mode with the nickname when
5683 * Moved silc_client_ch[u]mode[_char] functions from
5684 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5685 place sucks, they are utility functions and should be in some
5688 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5690 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5693 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Added TRQ (efficient deque and list library) into lib/trq. This is
5698 a very good list library that is currently used in the SILC. Defined
5699 SilcList API over the library because I didn't like the API very
5700 much. See lib/trq/silclist.h for the API and examples of how to
5701 use the API. Fixed various places in the code to use the new
5702 SilcList API. The SilcList is meant for lists that has a structure
5703 already defined as a list. It is not suitable to add just some
5704 context to the list (in TRQ, the context is the list actually).
5706 So, I defined SilcDList that can be used for the purpose where
5707 predefined list structure does not exit. This can be used as
5708 such list. Now some context just can be added to the SilcDList.
5709 Currently this list is not used in the SILC just yet, though there
5710 are a lot places where this can replace dynamically allocated
5711 tables and I will fix these places, later, to use SilcDList.
5712 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5713 and use TRQ internally).
5715 Also fixed some annoying warning messages that the original TRQ
5716 code generated. Also minor changes to TRQ's Makefile.in.
5718 * Added support for querying by Client ID to both WHOIS and
5719 IDENTIFY commands into server, as required by the protocol.
5721 * Removed method function pointers from SilcBuffer structure. They
5722 weren't used to anything and just increased the context size for
5723 no good reason. This change also made silc_buffer_alloc and
5724 silc_buffer_free functions inline functions.
5726 * Disabled command flooding detection support until it's fixed so
5727 that it accepts commands in but does not execute them more than once
5730 * Added silc_net_localhost(), to return local hostname, into
5731 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5732 that must be initialized before calling silc_client_init.
5734 * Added new function: silc_server_send_notify_on_channels to send
5735 notify messages to all channels client has joined. It is assured
5736 that the message is sent only once per client.
5738 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5739 lib/silcutil/silcutil.[ch] as silc_format function. The new
5740 function is generic and is used by server as well, not only by
5741 the logging routines.
5743 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5744 the provided version string was not acceptable. Added new function:
5745 silc_ske_check_version into lib/silcske/silcske.h. The function
5746 must be implemented by the application (client or server) and it
5747 does not reside in the SKE library. The function checks the version
5748 string remote end sent.
5750 * Added back pointers (to opaque context and to SilcSocketConnection)
5751 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5753 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5754 duplicate packet context structure.
5756 * Changed `notify' client operation to send same arguments as client
5757 receives from server except for ID's. ID's are mapped to correct
5758 ID entry and that is returned. Also, if channel entry is not sent
5759 by server but the notify is for channel the channel entry is sent
5760 to application (otherwise application doesn't know that it is for
5761 channel (library gets it from packet's Destination ID)).
5763 * Added silc_client_remove_from_channels into client library to
5764 remove a client from all channels it has joined to. Used when
5765 received SIGNOFF notify from server. Added also new function
5766 silc_client_replace_from_channels to replace old ID entry with
5767 new ID entry on all channels. Used when received NICK_CHANGE
5770 * Fixed ID Cache list handling in silc_idlist_get_client in
5771 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5772 to get (or query) client by ID.
5774 * Updated TODO list.
5776 * Added connection authentication status message defined by the
5777 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5778 support for these into the code in client and server side.
5780 * Added generic function silc_client_send_command to send any command
5781 with variable argument list. Application should use this function
5782 to send commands if the command functions provided by the library
5783 does not suite for the application's user interface needs.
5785 * Added new `failure' client operation. Application is notified about
5786 received failure packet if client is executing a protocol. In this
5787 case the protocol's execution has failed.
5789 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5790 is required by the protocol.
5792 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5793 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5796 * Added status flag to SilcSKE object to indicate realtime status
5797 of the SKE protocol.
5799 * Application receives now exactly same command reply arguments as
5800 the library receives from server. However, if ID is received the
5801 corresponding ID entry is returned to the application (eg. Client
5802 ID is mapped to correct SilcClientEntry entry and that is returned).
5803 Changed command_reply client operation due to this change.
5805 * Changed all ID's in commands and in command replys as ID Payloads.
5806 Change affected both client and server side codes.
5808 All ID's sent in SILC network (with execption of ID's in SILC
5809 Packet header) are sent in ID Payload to support variable length
5812 * Server now notifies nick changes and notifies all clients on
5813 the channels about the new nickname (about the new Client ID,
5816 * Implemented CMODE command to change channel modes. Supports all
5817 channel modes defined by the protocol specs except ban and invite
5818 lists. (Also, private channel key mode is supported but support for
5819 setting private channel key in client is missing, thus, this mode
5820 has no effect on client side (except that server requires that the
5821 client uses private channel key and normal channel traffic does not
5824 Also, invite mode works per se, but INVITE command does not work
5825 yet correctly, so you can set channel as invite only channel but
5826 inviting clients to the channel does not work (it is yet to be
5827 thought what's the best way to do it).
5829 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5830 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5831 Implemented CUMODE command to change user's mode on the channel.
5832 Supports all modes defined by the protocol specs.
5834 * Added NAMES command reply to return users modes on the channel.
5836 * Removed unnecessary and slow ciphers from lib/silccrypt.
5838 * Set SO_KEEPALIVE option to connection sockets by default.
5840 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5842 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5843 redefined the Notify Payload into protocol specs.
5845 * Added silc_id_payload_parse_id to get ID directly from raw
5848 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5851 accept searching by Client ID as well.
5853 * Added support for LEAVE and SIGNOFF notify types in client library.
5855 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5856 to parse ID Payload from raw data.
5858 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Added flags parameter into silc_ske_assemble_security_properties
5861 function in lib/silcske/silcske.[ch].
5863 * Changed notify client operation to fit better for notify messages
5864 sent by server. The notify payload received from server is now
5865 passed to the application (after parsing it to SilcNotifyPayload).
5866 It is application's responsibility to retrieve the arguments
5867 from the payload and show the message the way it wants. The message
5868 sent by server is implementation specific.
5870 * Changed public keys to comply with the protocol specification.
5871 Old public keys are not supported anymore and are not compatible.
5873 * Removed nickname from Channel Payload as the latest draft removed
5874 it. The client must resolve the nickname from the NAMES command
5875 reply received when it joined the channel.
5877 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5879 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Fixed some errors in protocol specification drafts.
5883 * Created lib/silccore/silcnotify.c to implement Notify Payload
5884 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5885 generic payloads described by protocol specifications. The file
5886 includes implementations for ID Payload and Argument Payload.
5888 * Changed Command Payload implementation to use the new Argument
5889 Payload. Changed command_xxxx_payload to command_payload_xxxx
5890 to comply with SILC coding conventions.
5892 * Added suppport for Argument Payload handling in Notify Payload
5893 implementation as protocol requires it. Added the new support
5894 into server and client lib as well.
5896 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Added support for multiple nicknames on same channel. [n] is
5899 added locally to the nickname if there are more than one same
5900 nicknames on the channel.
5902 * Server now sends all nicknames that matched WHOIS request.
5903 Client also shows the list received from server.
5905 * Added TOPIC command to client side. User can now set and show
5906 current topic on channel.
5908 * Added MOTD command to client and server. Also, server sends the
5909 motd when client connects to the server.
5911 * Changed version strings to comply ISO 8601.
5913 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Fixed protocol error handling in client library. It should now
5916 cope even if the SKE fails for some reason.
5918 * Made new protocol specification drafts for submitting to IETF.
5920 * Implemented TOPIC command to server in silcd/command.c.
5922 * Added two new notify types into lib/silccore/silcnotify.h:
5923 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5924 notify nickname change and topic setting/change on a channel.
5926 * API change of command_reply operation in client library. The
5927 application gets now the status type received from server as well.
5929 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5933 * Cras fixed and optimized the packet handling even further and
5934 it should work now. Minor change to the prototype of function
5935 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5937 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added new function into lib/silcutil/silcschedule.[ch]:
5940 silc_schedule_with_fd to select() a specified fd. The function
5941 returns after timeout expires or data arrives or goes. The
5942 function is used by packet routines to wait that all data is
5943 received from network.
5945 * Fixed data reading from network in lib/silccore/silcpacket.c.
5946 The code now assures that all data is read from the fd and then
5947 continues packet processing. This was a bug fix since the code
5948 used to drop some data in some circumstances.
5950 * Added new function into lib/silcclient/client.[ch]:
5951 silc_client_start_key_exchange to start key exchange after
5952 connection has been established to server. The code internally
5953 now uses this funtion but its main purpose was to provide it
5954 for applications that perform their own connecting. After
5955 application has created a connection it merely calls this
5956 function to start the key exchange between client and server.
5957 The library takes care of everything else after that.
5959 Updated also lib/silcclient/README to explain the usage of
5962 * Do not send to application information that connection has
5963 been established. Application gets notified it by connect
5966 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Applied cras's patch to add silc_schedule_one function. The
5969 function runs scheduler once and returns.
5971 * Fixed the scheduler after cras messed it up. The timeout
5972 handling works now as it's supposed to work.
5974 * Added into lib/silccore/ silcnotify.h to include notify
5975 message types support. Changed silc_server_send_notify*
5976 functions, in server.[ch], to support those new notify types.
5977 Added the support for the notify types into client library,
5978 as well. Added new notify client operation into ops.h in
5981 * Changed silc_server_packet_send_to_channel to send normal
5982 packets instead of just channel message packets. The function
5983 is now used to send the notify packets to channels. It is not
5984 used to send channel message packets anymore, as server never
5987 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5988 va_arg()s as it seems to require it nowadays. I guess, if SILC
5989 is compiled with older va_arg() the new code should work anyway.
5991 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Splitted core library. Core library (lib/silccore) includes
5994 now only SILC protocol specific core (and common) components.
5995 Created new utility library (lib/silcutil) that includes more
5996 generic purpose stuff. The stuff for util library was taken
5997 from the old core library. This was minor and easy split.
5999 * Created SILC Client Library (lib/silcclient) that includes
6000 implementation of the SILC client without user interface. This
6001 was major move from silc/ directory. The code has been changed
6002 so that it is transparent towards the user interface. The
6003 silc/ directory includes now the same user interface as before
6004 and it uses the new client library. Read lib/silcclient/README.
6005 Basicly, the client library performs everything else related
6006 to SILC except user interface handling. Also, configuration
6007 files are considered to be part of user interface and library
6008 does not handle them.
6010 This change also changed a lot of structures, function naming etc.
6011 Most important change was that SilcClientWindow object was
6012 renamed to SilcClientConnection in the client library. Created
6013 also new file lib/silcclient/ops.h. Also added new files
6014 silc/local_command.[ch] and silc/client_ops.[ch].
6016 All these changes were made to make it easier for user interface
6017 designers to create what ever user interface for the SILC client
6020 It is also expected that the server will be moved to lib
6021 directory as well and SILC Server Library will be created;
6022 sometimes in the future.
6024 * Removed Local commands from lib/silccore/silccommand.h as
6025 they are application specific and new client library does not
6026 handle any of those anymore.
6028 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6029 old client implementation in silc/.
6031 * Added support for callback functions in SILC_LOG_* macros.
6032 Application can now set its own callbacks that will be called
6033 instead of using the default functions that will always print
6034 the debug messages to stderr (or stdout). Also, debugging can
6035 now be disabled by setting silc_debug to FALSE and re-enabled by
6036 setting it to TRUE. Note, that logging will still work even
6037 if debugging is disabled.
6039 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6040 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6041 silc_log_reset_debug_callbacks.
6043 * To enable debugging in silc client one must give now -d
6044 option on command line.
6046 * Changed silc_schedule_init to automatically allocate task queues
6047 if they are not allocated before calling it.
6049 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Added GMP 3.1 into math library.
6053 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6056 a channel in SILC network. The packet is used by servers and
6057 routers to notify other routers that user has left a channel.
6058 This little feature was missing until now. Added the feature
6059 to protocol specification as well.
6061 Added functions: silc_server_send_remove_channel_user and
6062 silc_server_remove_channel_user into server.[ch].
6064 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6065 lib/silccore/silcpacket.h. However, they are not implemented
6068 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Fixed joining to a channel and sending channel messages
6071 between server and router. The channel message sending should
6072 now work inside a cell.
6074 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Fixed the private message sending between server and router.
6077 The private message sending should now work inside a cell.
6079 * Added silc_server_replace_id into server.[ch] to replace
6080 existing ID in the SILC network.
6082 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6083 and silc_idlist_replace_server_id into idlist.[ch] in server.
6085 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Fixed the server to server connections. Server can again now
6088 connect to router. Router to router connections probably does
6091 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Added dynamic protocol registering support. Now protocols can
6094 registered and unregistered on the fly. Patch by cras.
6096 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Added lib/contrib directory to hold routines that some platforms
6099 don't have but are needed by SILC.
6101 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6102 into lin/contrib to provide getopt() and getopt_long() for
6103 those who don't have it.
6105 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added AWAY command to client. When away message is set and
6108 client receives a private message packet the client automatically
6109 replies to the sender with the away message.
6111 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6112 bug seemed to be the cause of recent problems when compiling
6115 * Added version detection support to SKE protocol specification
6116 and added the new changes to the SKE implementation as well.
6117 There were other minor changes in the SKE protocol as well.
6119 Many changes in lib/silcske/silcske.[ch] and in
6120 lib/silcske/payload.[ch].
6122 * Added ^U functionality, clear input line. Patch from cras.
6124 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Mainly small bugfixes on core library. Fixed some debugging
6127 logging and buffer overflow in silclog.c.
6129 * Updated config.sub and config.guess on the distribution tree.
6131 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * Added command lagging support in server. Client may execute
6134 commands now only once in two seconds.
6136 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Optimized packet reception. MAC computation and checking is now
6139 also more optimized. A lot previously duplicated code is now
6140 used as generic by both client and server.
6142 * Fixed key pair generation in clientutil.c
6144 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Added into lib/silccore/silcbufutil.[ch] new function;
6147 silc_buffer_realloc.
6149 * Moved generic packet sending/encryption functions to
6150 lib/silccore/silcpacket.[ch] from client and server. Some
6151 rewriting of the functions.
6153 * Moved all generic packet reception/decryption functions to
6154 lib/silccore/silcpacket.[ch] from client and server. The
6155 packet processing is now much cleaner in both client and server.
6156 These were major changes in both client and server.
6158 * Created many common functions in server to do packet sending.
6159 Previously code were duplicated a lot, this has been removed
6162 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Rewrote major parts of the ID cache system. Don't know
6165 whether it is better now or not but at least the API is more
6168 * Major rewrite on ID cache stuff on client because of the ID
6169 cache API changes. Added idlist.c to client.
6171 * Also major rewrite on ID cache stuff on server as well.
6172 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6173 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6174 in hand, instead they are all put into the ID cache system now.
6175 All server_idlist_* routines uses ID cache now instead of
6176 traversing its own lists (those lists does not exist anymore).
6177 SilcIDList though still exists. Also, SilcXXXEntry's are
6180 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Finally made the SKE implementation compliant to the protocol
6183 specification. All mp integers are now binary encoded as
6184 opposed being HEX encoded.
6186 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6189 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6190 functions: silc_[encode/decode]_pem. Also added function
6191 silc_encode_pem_file to PEM encode with newlines ('\n') for
6194 * SILC public keys are now encoded either PEM or binary. Same
6195 option is for private keys as well. By default private keys
6196 are binary encoded and public keys PEM encoded. Silly HEX
6197 encoding were removed.
6199 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6200 function to create fingerprints.
6202 * Fixed a bug in SHA1; does not change the original data anymore.
6204 * Partly implemented INFO command on client and server side.
6205 Fixed CLEAR command. Changes to SERVER command; show current
6206 server(s) when giving command without arguments. Added
6207 VERSION command to client.
6209 * Added check to server that unregistered connections cannot
6210 execute commands (unless it is specificly allowed).
6212 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Fixed screen refresh.
6216 * Fixed channel joining bug from client. On some circumstances
6217 client tried to join to a channel it had already joined.
6219 * Added public key verification process into client's protocol.c.
6220 The client now verifies the public key from user and saves
6221 it into ~./silc/serverkeys/ directory.
6223 Added into: clientutil.[ch]: silc_client_verify_server_key.
6225 * Changed SKE protocol's silc_ske_initiator_finish function
6226 to accept callback function that verifies the received public
6227 key. Removed old silc_ske_verify_public_key function.
6229 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6232 silc_pkcs_private_key[_data]_set.
6234 * Made the password and public authentication more cleaner in
6235 server's protocol.c.
6237 * Removed historic and obsolete protocol `channel_auth' from
6238 both client and server.
6240 * Removed wrong way of sending command status messages from
6241 server to client in server's command.c. The old way violated
6242 protocol specification.
6244 Changes to silccore/silccommand.[ch]: removed
6245 silc_command_encode_status_payload -> not needed anymore,
6246 changed silc_command_encode_payload_va to accept extra
6247 argument on variable argument list. The argument type must
6248 now be provided to the function. Also, added new function:
6249 silc_command_encode_reply_payload_va which is same as
6250 normal command_encode_payload_va except command status type
6251 is provided as extra argument.
6253 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Added ~./silc directory handling. The directory includes the
6256 public and private keys for the client.
6258 Added silc_client_check_silc_dir, silc_client_create_identifier
6259 and silc_client_load_keys.
6261 * Implemented SILC protocol compliant public key. Added public
6262 and private key saving to and loading from files.
6264 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6265 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6266 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6267 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6268 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6270 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6271 silc_pkcs_load_[public/private]_key.
6273 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Added silc_server_get_route (route.[ch]) to get connection
6276 data for the fastest route for given ID.
6278 * Implemented INVITE command on client and server. The command
6279 were re-defined in the SILC Protocol Specification and the
6280 implementation now complies with the specification.
6282 * Implemented PING command on client and server.
6284 * Implemented NAMES command on client and server. The server side
6285 supports currently only normal server not router server yet.
6286 Some changes to NAMES definition in SILC protocol specification.
6288 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Implemented LEAVE command on client and server.
6292 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6293 again. This change was made to the protocol as well. Server
6294 should not violate the protocol specification anymore.
6296 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6299 was tested. SOCKS4 was not but should work anyway.
