29 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
31 * Fixed LIST command reply sending in server. Affected file
34 * Server now sends the kicker's client ID in the KICK notify
35 to the kicked client. Affected file silcd/command.c.
37 * The client library now parses the kickers client ID and
38 UI displays it. Affected files lib/silcclient/client_notify.c
39 and irssi/src/silc/core/silc-channels.c, module-formats.c.
41 * Made all payload parsing function prototypes consistent.
42 They all take now const unsigned char * and uint32 pair as
43 the payload data instead of SilcBuffer. Changes all around
44 the source tree. Other unsigned char* -> const unsigned char*
45 changes around the tree as well.
47 * Optimized SFTP client and server packet sending not to
48 allocate new buffer for each packet but to recycle the
49 first allocated buffer. Affected files are
50 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
52 * Optimized the SFTP client to use SilcList instead of
53 SilcDList for requests, because it is faster. Affected file
54 is lib/silcsftp/sftp_client.c.
56 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
57 into lib/silccore/silcid.[ch].
59 Renamed silcpayload.[ch] into silcargument.[ch].
61 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
63 * If client entry is deleted with active key agreement
64 session, abort the session.
66 The silc_client_abort_key_agreement now calls the completion
67 callback with new SILC_KEY_AGREEMENT_ABORTED status.
69 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
72 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
74 * Don't use __restrict in older GCC's. Affected file is
75 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
77 * silc_net_localhost now attempts to reverse lookup the
78 IP/hostname. Affected file lib/silcutil/silcnet.c.
80 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
81 command. It can be used to gain founder privileges at
82 the same time when joining the channel.
84 Defined that the SILC_NOTIFY_TYPE_KICKED send the
85 kicker's client ID as well. Updated protocol specs.
87 Defined that the server must send SILC_COMMAND_IDENTIFY
88 command reply with error status to client who sent
89 private message with invalid client ID.
91 Updated the protocol specification.
93 * Added silc_server_send_command_reply to send any
94 command reply. Affected file silcd/packet_send.[ch].
96 * Added silc_id_payload_encode_data to encode ID payload
97 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
99 * The server now send IDENTIFY command reply with error
100 status if client ID in private message is invalid. Affected
101 file silcd/packet_receive.c.
103 * Save the server key file with server's IP address in
104 the filename instead of hostname. The affected file is
105 irssi/src/silc/core/client_ops.c.
107 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
109 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
112 * Added libtool support for compiling shared objects in
113 lib/silcsim. Affected file configure.in.pre and
114 lib/silcsim/Makefile.am. Original patch by cras.
116 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Pid file configuration, and server's config file fixes
119 patch by toma. Updated CREDITS file.
121 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
123 * Fixed silc_client_channel_message to not try to decrypt
124 the message twice if it resolved the destination client
125 information. This could cause of dropping one channel
126 message. Affected file lib/silcclient/client_channel.c.
128 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Added silc_client_run_one into lib/silcclient/silcapi.h and
131 lib/silcclient/client.c. This function is used when the SILC
132 Client is run under some other scheduler, or event loop or
133 main loop. On GUI applications, for example this may be
134 desired to used to run the client under the GUI application's
135 main loop. Typically the GUI application would register an
136 idle task that calls this function multiple times in a second
137 to quickly process the SILC specific data.
139 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
141 * Fixed silc_server_drop() for dropping the supplementary
142 groups as well, this could cause a security hole on some
145 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
147 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

151 to run server on foreground. A patch by debolaz.
152 Affected files silcd/server.c, silcd/silcd.c.
154 * Fixed MOTD to return the MOTD file server name. Affected
155 file silcd/command.c.
157 * Added INFO command reply handling to the Irssi SILC Client.
158 Affected file irssi/src/silc/core/client_ops.c.
160 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
162 * Fixed the silc_idcache_list_* routines to really support
163 the dynamic list. Fixes a crash. Affected file is
164 lib/silccore/silcidcache.c.
166 * Fixed the LIST command reply to really call LIST command's
167 pending callbacks. Affected file silcd/command_reply.c.
169 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
171 * Update conn->local_entry->nickname after giving NICK
172 command. Affected file lib/silcclient/command.c.
174 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
176 * Added the [pid] option to the silcd configuration file
178 Affected files: serverconfig.[ch] and silcd.c
180 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
182 * Save fingerprint in WHOIS command reply in server.
183 Affected file silcd/command_reply.c.
185 * Fixed NICK commands pending callback registration.
186 Affected file lib/silcclient/command.c.
188 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Use ++server->cmd_ident when sending commands in server,
191 instead of random number. Affected file silcd/command.c.
193 * Fixed GETKEY command reply to call actually GETKEY pending
194 command callbacks. Affected file silcd/command_reply.c.
196 * A bit stricter check for nicknames. Check for same nickname
197 in NICK command also. Affected file silcd/command.c.
199 * Do not call INFO command everytime client ID changes, only
200 during first connecting. Affected file lib/silcclient/client.c.
202 * Set the new nickname only after successful command reply for
203 NICK command is returned by server. Affected file
204 lib/silcclient/command.c.
206 * Remove nicknames from nicklist during server_signoff notify.
207 Should fix /NAMES bit more. The affected file is
208 irssi/src/silc/core/silc-channels.c.
210 * Added `fingerprint' field to the SilcIDListData in the
211 silcd/idlist.h to hold the fingerprint of the client's
214 Send the fingerprint of the client's public key in WHOIS
217 Affected files silcd/command.c, and silcd/idlist.[ch].
219 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
220 create fingerprint from given data.
222 * Show the fingerprint of the client's public key in WHOIS.
223 Affected files irssi/src/module-formats.[ch] and
224 irssi/src/silc/core/client_ops.c.
226 * Format the multiple same nicknames also during JOIN and
227 NICK_CHANGE notifys. Affected file is
228 lib/silcclient/client_notify.c.
230 * Do not print error on screen for invalid private message
231 payload since it can come if someone is sending private
232 messages with wrong key. Affected file
233 lib/silccore/silcprivate.c.
235 * Fixed multiple concurrent /PING crash. Affected file
236 lib/silcclient/command.c.
238 * Changed the wrong ID encoding. All IP addresses must be
239 in MSB first order in encoded format. They were encoded
240 wrong and was in LSB format. Affected files are
241 silcd/serverid.c, lib/silcutil/silcutil.c.
243 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
245 * Call the `connect' client operation through the scheduler
246 in case of error. Affected file lib/silcclient/client.c.
248 * Call the `failure' client operation even if the error
249 occurred locally during a protocol. Affected file is
250 lib/silcclient/protocol.c.
252 * Added support of sending LIST command to router from normal
253 server. This way normal server can get list of all channels
254 in the network too. Fixed the channel list sending in the
255 server too. Affected files are silcd/command.c, and
256 silcd/command_reply.[ch].
258 * Added silc_server_update_channels_by_server and
259 silc_server_remove_channels_by_server. They are used during
260 disconnection of primary router and in backup router protocol.
261 Affected file silcd/server_util.[ch], silcd/server.c and
262 silcd/server_backup.c.
264 * Fixed channel adding to global list in IDENTIFY command
265 reply in server. Affected file silcd/command_reply.c.
267 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
269 * If the incoming packet type is REKEY or REKEY_DONE process
270 that packet always synchronously. Fixes yet another MAC
271 failed error on slow (dialup) connections. Affected file
272 lib/silcclient/client.c and silcd/server.c.
274 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
276 * Call check_version SKE callback for initiator too. Affected
277 file lib/silcske/silcske.c.
279 * Implemented fix for security hole found in the SKE that was
280 fixed in the specification few days back; the initiator's
281 public key is now added to the HASH value computation.
282 Added backwards support for the old way of doing it too, for
283 old clients and old servers. Affected file is
284 lib/silcske/silcske.c.
286 * Enabled mutual authentication by default in SKE. If initiator
287 is not providing mutual authentication the responder will
288 force it. This will provide the proof of posession of the
289 private key for responder. The affected files are
290 lib/silcclient/protocol.c and silcd/protocol.c.
292 * Do not cache anymore the server's public key during SKE.
293 We do mutual authentication so the proof of posession of
294 private key is done, and if the server is authenticated in
295 conn auth protocol with public key we must have the public
296 key already. Affected file silcd/protocol.c.
298 * Added new global debug variable: silc_debug_hexdump. If
299 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
300 file lib/silcutil/silclog.[ch].
302 * Fixed compilation warning due to char * -> const char *.
303 Affected files lib/silcutil/silcnet.h, and
304 lib/silccore/silcauth.[ch].
306 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
308 * Fixed CMODE command when new channel key was created. If
309 the creation failed the old key was removed. Next time giving
310 same command would crash the server since the old key was
311 freed already. Affected file silcd/command.c.
313 * Fixed the silc_server_announce_get_channels to not crash
314 on reconnect. Affected file silcd/server.c.
316 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Added silc_log_set_debug_string function to set a regex
319 string to match for debug output. Only the function names,
320 or filenames matching the given debug string is actually
321 printed. This way it is possible to filter out those debug
322 strings that user is not interested in.
324 Fixed a bug in silc_string_regexify.
326 Affected files lib/silcutil/silclog.[ch], and
327 lib/silcutil/unix/silcunixutil.c.
329 * Changed the -d options in both server and Irssi SILC client
330 to take the debug string as argument. Affected files
331 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
333 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
335 * Added silc_hash_babbleprint to create a Bubble Babble
336 Encoded fingerprint. The encoding is developed by Antti
337 Huima (draft-huima-babble-01.txt), and it creates human
338 readable strings out of binary data. Affected file
339 lib/silccrypt/silchash.[ch].
341 * Print the babble print now in addition of fingerprint as well
342 in Irssi SILC client. Affected files are
343 irssi/src/fe-common/silc/module-formats.[ch],
344 irssi/src/fe-common/silc/core/client_ops.c.
346 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
348 * Fixed a security problem found in SKE. The initiator's
349 public key too is now added to the HASH hash value creation
350 which is signed by the responder to create the SIGN value.
351 This will prevent anyone in the middle to lie to the responder
352 about the initiator's public key. If this is done now, the
353 man in the middle will get caught. Updated the protocol
356 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Better installation directory handling. Configure module
359 paths and other paths automatically to example_silc* files
360 in doc/. A patch by toma.
362 * Fixed compiler warning from MPI library, and from SILC RNG.
365 * Added SILC_SERVER_PID_FILE to define the pid file for server.
366 It can be configured with ./configure. A patch by toma.
368 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
370 * Find correct make to use in prepare-clean. A patch by
371 toma. Affected file prepare-clean.
373 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
375 * Added irssi variables use_auto_addr, auto_bind_ip,
376 auto_bind_port and auto_public_ip.
378 * Changed the interface for silc_client_send_key_agreement
379 in lib/silcclient/silcapi.h
383 irssi/src/silc/core/silc-core.c
385 lib/silcclient/silcapi.h
386 irssi/src/silc/core/silc-channels.c
387 lib/silcclient/client_keyagr.c
390 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
392 * Added silc_pkcs_public_key_compare to compare two
393 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
395 * Check that the client who set the founder mode on the
396 channel is the same client that is giving the founder
397 mode to itself. It is done by comparing the saved public
398 key (it is saved even in the authentication is passphrase).
399 Affected file silcd/command.c.
401 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
403 * Do not process packet for disconnected socket connection.
404 Affected file lib/silccore/silcpacket.c.
406 * Process the DISCONNECT packet through scheduler in the
407 client library. Affected file lib/silcclient/client.c.
409 * Fixed the silc_client_packet_parse to not to increase
410 the packet sequence number if the conn->sock and the
411 current socket connection is not same. This can happen
412 for example during key agreement when the conn includes
413 multiple socket connections (listeners). Affected file
414 lib/silcclient/client.c.
416 * The sender of the file transfer request now provides also
417 the pointer (listener) for the key exchange protocol. If
418 the listener cannot be created then it sends empty key
419 agreement and lets the receiver provide the listener.
421 Added `local_ip' and `local_port' arguments to the
422 silc_client_file_send. If they are provided they are used,
423 if not then it will attempt to find local IP address, if
424 not found or bind fails then the remote client will provide
427 Affected files are lib/silcclient/client_ftp.c and
428 lib/silcclient/silcapi.h.
430 * Extended the FILE SEND command to support defining the
431 local IP and port for key exchange listener. They are
432 optional. Affected file irssi/src/silc/core/silc-servers.c.
434 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
436 * Defined to WHOIS command reply the sending of fingerprint
437 of the client's public key (if the proof of posession of the
438 corresponding private key is verified by the server).
439 Updated to the protocol specification.
441 * Added support of receiving the client's public key's
442 fingerprint in command reply in client library. Affected
443 file is lib/silcclient/command_reply.c, and
444 lib/silcclient/idlist.[ch].
446 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
448 * Do not send over 128 chars long nickname to the server
449 in NICK command. Affected file lib/silcclient/command.c.
451 * Do not send over 256 chars long channel names to the server
452 in JOIN command. Affected file lib/silcclient/command.c.
454 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
456 * Assure that silc_server_close_connection cannot be called
457 twice for same socket context. Affected file is
460 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
462 * Send error message to application if opening file for
463 writing during file transfer fails. Affected file is
464 lib/silcclient/client_ftp.c.
466 Remove all file transfer sessions for a client that we're
467 removing from ID cache.
469 Affected file is lib/silcclient/client_ftp.c.
471 * Fixed silc_net_addr2bin to return correct address. Affected
472 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
474 * Fixed file transfer session removing on signoff notify.
475 Affected file irssi/src/silc/core/silc-servers.c.
477 * Added the SilcClientFileError to be returned in the monitor
478 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
479 Affected file lib/silcclient/silcapi.h.
481 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Fixed a crash in silc_client_ftp_free_sessions and
484 silc_client_ftp_session_free_client. Affected file
485 lib/silcclient/client_ftp.c.
487 * Added `disabled' field in the SilcChannelEntry in the server
488 to indicate if the server entry is disabled. Affected file
489 silcd/idlist.h, silcd/command[_reply].c.
491 * SILC server adds now /var/run/silcd.pid everytime it is
492 started. Affected file silcd/silcd.c.
494 * Added silc_server_packet_send_clients to send a packet to
495 the provided table of client entries. Affected file
496 silcd/packet_send.[ch].
498 * Fixed a crash in client resolving in client_prvmsg.c in
499 client library. Affected file lib/silcclient/client_prvmsg.c.
501 * Do not actually remove the client directly from ID cache
502 during SERVER_SIGNOFF, but invalidate it. This way we
503 preserve the WHOWAS info for the client. Affected file
506 * Fixed SERVER_SIGNOFF notify handling in the server. The
507 server is now able to process incoming SERVER_SIGNOFF notify
508 for a server that it doesn't even know about. It will remove
509 the clients provided in the notify. Affected file
510 silcd/packet_receive.c.
512 * Check for partial packet in data queue after every packet that
513 was found from the queue. Return and wait for more data if
514 there is partial data in queue. Affected file is
515 lib/silccore/silcpacket.c.
517 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Added SilcClietFileError enum to indicate error in
520 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
521 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
522 Affected files lib/silcclient/silcapi.h and
523 lib/silcclient/client_ftp.c.
525 * Check that newsize in silc_buffer_realloc is larger than
526 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
528 * Added better monitor of file transfers. It now monitors
529 key agreement protocol during the file transfer too. Added
530 error reporting too. Affected files
531 irssi/src/silc/core/silc-servers.c,
532 irssi/src/fe-common/silc/module-formats.[ch].
534 * Wrote a help file for FILE command.
536 * Added silc_rng_global_get_byte_fast to get not-so-secure
537 random data as fast as possible. Random data is read from
538 /dev/urandom if available and from the SILC RNG if not
539 available. It is used in padding generation. Affected file
540 lib/silccrypt/silcrng.[ch].
542 * All packets in client library are now processed synchronously.
543 Optimized packet processing a lot. Affected file
544 lib/silcclient/client.c.
546 * All server connection packets are processing synchronously
547 now in server, to optimize packet processing. Affected file
550 * Include files are installed now only in Toolkit distribution
551 if make install is given. Affected files: all Makefile.am's.
553 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
555 * Assure that silc_client_notify_by_server_resolve does not
556 resolve the client information multiple times. If it cannot
557 be found by the first it cannot be found at all. Affected
558 file lib/silcclient/client_notify.c.
560 * Fixed WHOWAS command reply calling. Affected file
561 lib/silcclient/command_reply.c.
563 * Removed all references to silc_idlist_get_client from the
564 Irssi SILC client since that call is internal call used by
565 the library. The Irssi SILC client will use now client
566 retrieval functions found in silcapi.h.
568 * Fixed a bug in resolving nickname info before sending

633 lib/silcutil/silcutil.[ch].
635 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Resolve the client info when received private message or
638 channel message for a client which nickname we don't know.
639 Affected files lib/silcclient/client_prvmsg.c and
640 lib/silcclient/client_channel.c.
642 * Do not crash in /KEY if client is not connected. Affected
643 file irssi/src/silc/core/silc-channels.c.
645 * Added SilcClientStatus field to the SilcClientEntry in the
646 lib/silcclient/idlist.h.
648 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
649 is incomplete and is being resolved, it won't be resolved
652 Make sure also that USERS command reply does not resolve
653 twice information. Affected file is
654 lib/silcclient/command_reply.c.
656 Make sure that silc_client_get_clients_by_list does not
657 resolve twice same information.
659 * Check for valid client->id in the silc_server_free_client_data.
660 Affected file silcd/server.c.

675 * Call the silc_server_udpate_servers_by_server in the
676 primary router that comes back online in the backup resuming
677 protocol. Otherwise it routes packets wrong. Affected file
678 silcd/server_util.[ch], silcd/server_backup.c.
680 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
682 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the

685 * Redefined the SILC packet header to include the padding
686 length. Affected file lib/silccore/silcpacket.[ch].
688 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
689 length for maximum padding up to 128 bytes). Affected
690 file lib/silccore/silcpacket.h.
692 * Removed all backwards support for old 0.5.x MAC thingies.
693 The SILC packet header change makes it impossible to be
694 backwards compatible.

697 protocol. This is to assure that all routers has connected
698 to the primary router. Affected file silcd/server_backup.c.
700 * Changed the RNG to take the first IV from random data. It
701 used to take it from zero actually. Changed the RNG also
702 to use /dev/urandom during session. /dev/random is used
703 in initialization. Affected file lib/silccrypt/silcrng.[ch].
705 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Changed the SILC packet header to have the first two bytes
708 (the packet length) encrypted. Affected files aroung the
709 code tree, lib/silccore/silcpacket.[ch]. Removed the
710 SilcPacketCheckDecrypt callback. It is not needed anymore
711 since the silc_packet_receive_process will determine now
712 whether the packet is normal or special.
714 * Implemented the unidirectional MAC keys. Affected files
715 lib/silcske/silcske.c, silcd/protocol.c and
716 lib/silcclient/protocol.c.
718 * Implemented the packet sequence number to the MAC computation.
719 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
720 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
721 lib/silcclient/protocol.c.
723 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
725 * Allow backup router to announce servers. All servers
726 announced by backup router are added to the global list
727 automatically. Update hte server's socket to our primary
728 router also when backup router announces a server.
729 Affected file silcd/packet_receive.c.
731 * Do not update the client->router in the function
732 silc_server_udpate_clients_by_server if the client is on
733 global list. We might fail to find any specific server
734 for locally connected clients and local cell clients. They
735 should still use the `from' and not `to' as client->router.
736 This fixes backup router resuming protocol. Affected file
739 * Decrease channel statistics count only if the channel
740 deletion worked. Affected files are silcd/server.c and
743 * Added silc_server_update_servers_by_server to update origin
744 of all server entries. Used during backup router protocol.
745 Affected files silcd/server_util.[ch], silcd/server.c. and
746 silcd/backup_router.c.
748 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
749 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
750 silc_hmac_get_hash and silc_hmac_get_name. Affected file
751 lib/silccrypt/silchmac.c.
753 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Assure that router cannot reroute the same channel message
756 to the sender. Affected file silcd/packet_receive.c.
758 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
760 * Made better checks that the channel message is not sent
761 to the router it came from. Affected file is
762 silcd/packet_send.c. Fixed memory leak too.

765 only after checking if it is replaced by backup router.
766 Affected file silcd/packet_receive.c.
768 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Fixed the backup resuming protocol to work in multiple
771 router environment. Affected file silcd/server_backup.c.
773 * Route packet only to one router in the function
774 silc_server_packet_send_to_channel. Affected file is
777 * Fixed silc_server_send_notify_dest to set the broadcast
778 flag. Fixed the silc_server_send_notify_topic to actually
779 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
780 Affected file silcd/packet_send.c.
782 * Changed the SFTP Filesystem interface. Changed the
783 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
784 the filesystem operation function. The SilcSFTPFilesystem
785 is now a context that is allocated by all filesystem allocation
786 functions and it already includes the operations structure
787 and filesystem specific context. It is given as argument
788 now to the silc_sftp_server_start. This made the interface
789 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
790 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
792 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Changed the backup router adding and getting interfaces
795 in the server. The router that will be replaced by the
796 specified backup router is now sent as argument. Affected
797 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
800 * Added silc_net_addr2bin_ne to return the binary form of
801 the IP address in network byte order. Affected files
802 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
804 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
806 * Check for existing server ID in silc_server_new_server
807 and in silc_server_connect_to_router_final and remove the
808 old entry if it exists. Affected file silcd/packet_receive.c,

818 protocol specification.
820 * Removed one redundant channel key generation from normal
821 server during joining procedure. Removed one redundant
822 channel key sending from server to router during joining
823 procedure. Affected file silcd/command.c.
825 * Made minor bugfixes to the backup router resuming protocol.
826 Affected file silcd/server_backup.c, server.c.
828 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

831 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
834 * Implemented the backup resuming protocol that is used to
835 resume the primary router position in the cell after the
836 primary router comes back online. Affected files
837 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
838 and silcd/server_util.[ch].

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

963 entry always, not just when the command is coming from client.
964 Affected file silcd/command.c.
966 * Added new function silc_server_packet_queue_purge to purge the
967 outgoing data queue to the network. After the function returns
968 it is guaranteed that the outgoing packet queue is empty.
969 Affected file silcd/packet_send.[ch].
971 * Purge the outgoing packet queue in the rekey protocol's final
972 callback to assure that all rekey packets go to the network
973 before quitting the protocol. Affected file silcd/server.c.
975 * Added silc_client_packet_queue_parse as similar function as
976 in server to the client library. The affected file is
977 lib/silcclient/client.c.
979 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Splitted silcd/server.c and created silcd/server_util.[ch]
982 for utility functions.
984 * Added new socket flag SILC_SF_DISABLED to indicate that the
985 connection is open but nothing can be sent to or received from
986 the connection. Affected file lib/silcutil/silsockconn.[ch].
987 The checking for disabled socket is checked in the low level
988 silc_socket_write and silc_socket_read functions.
990 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Allow only nicknames and channel names that fits into the
993 7-bit unsigned char ASCII set. Affected file silcd/command.c.
995 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
997 * When processing JOIN command reply in server check that if
998 the channel exists in our global list we'll move it the local
999 list. Affected file silcd/command_reply.c.
1001 * Fixed the check whether client is joined on the channel already
1002 in JOIN command. Affected file lib/silcclient/command.c.
1004 * Fixed the JOIN command reply to check whether the channel
1005 already exists. Affected file lib/silcclient/command_reply.c.
1007 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Added silc_ske_status_string to map the SKE error numbers
1010 to readable strings. The affected files are
1011 lib/silcske/silcske[_status].[ch].
1013 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Do not show the private channels on the WHOIS channel list
1016 as it is not allowed by the protocol. The affected file is
1019 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Assure that the packet length digged from the actual packet
1022 is something sensible in the silc_packet_decrypt_rest_special
1023 in lib/silccrypt/silcpacket.c.
1025 * Free and NULL the allocated pointer in silc_hmac_alloc if
1026 the HMAC allocation fails. The affected file is
1027 lib/silccrypt/silchmac.c.
1029 * Print the selected security properties to the log files in
1030 the server. Affected file silcd/protocol.c.
1032 * Add SKE's reference counter even if calling the completion
1033 callback manually. Otherwise it goes negative, although it
1034 does not cause any problems. The affected file is
1035 lib/silcske/silcske.c.
1037 * Remove the client entry with short timeout after giving the
1038 KILL command. Affected file lib/silcclient/command.c.
1040 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1041 case all found clients are already disconnected (WHOWAS would
1042 found them) in the server. Affected file silcd/command.c.
1044 * Update the last_receive (time of last data received) to be
1045 updated only when received private or channel message so that
1046 the idle time showed in WHOIS makes more sense.
1048 * Added boolean field `valid' in to the SilcClientEntry in the
1049 client library to indicate whether the entry is valid or not.
1050 This fixes the nickname change bug on channel when changing
1051 the nickname to be same than the old (like nick to Nick) the
1052 nickname formatter doesn't set the new nick anymore to Nick@host.
1053 Affected file lib/silcclient/idlist.[ch].
1055 * Now actually fixed the nickname changing on disconnection.
1056 Added new function silc_change_nick to the Irssi SILC Client.
1057 Affected file irssi/src/silc/core/client_ops.c,
1058 irssi/src/silc/core/silc-nicklist.[ch].
1060 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Check that the public key exists in the GETKEY command before
1063 trying to encode it. Affected file silcd/command.c.
1065 * Print some notifications on received public keys with GETKEY
1066 command in the Irssi SILC Client. Affected files are
1067 irssi/src/fe-common/silc/module-formats.[ch],
1068 irssi/src/silc/core/client_ops.c.
1070 * Use IDENTIFY command to resolve the server information in the
1071 GETKEY command instead of INFO command. Affected file
1072 lib/silcclient/command.c.
1074 * All command reply functions in the client library now calls
1075 the pending command reply callbacks even if an error has
1076 occurred. The server has done this a long time and now it was
1077 time to move the client library to this as well. Now all
1078 errors can be delivered back to the pending command reply
1079 callbacks if necessary. Affected files are
1080 lib/silcclient/command[_reply].[ch].
1082 * Change the nickname on disconnection back to the username
1083 because in reconnect the server will enforce it to it anyway.
1084 Affected file irssi/src/silc/core/silc-servers.c.
1086 * Fixed a config file parsing bug in the Irssi SILC client.
1087 Affected file irssi/src/silc/core/clientconfig.c.
1089 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * When printing the channel mode on JOIN, verify that the
1092 channel key and channel's HMAC are valid. Affected file
1093 irssi/src/silc/core/client_ops.c.
1095 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1098 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1099 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1101 * Removed channel key rekey task deleting from the function
1102 silc_server_save_channel_key. Affected file silcd/server.c.
1103 Added explicit timeout task context instead that is used to
1104 delete the task if we are registering a new task before the
1105 new task has elapsed.
1107 * When channel key rekey occurs the client library now saves
1108 the old channel key for a short period of time (10 seconds) and
1109 is able to use it in case some is still sending channel
1110 messages encrypted with the old key after the rekey. Affected
1111 file lib/silcclient/[idlist.h|client_channel.c].
1113 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Added check to the silc_server_new_id_real to not accept
1116 new ID if it is the sender's own ID. Affected file is
1117 silcd/packet_receive.c.
1119 * Assure that we do not announce ourself or the one we've
1120 sending our announcements when we're router and are announcing
1121 servers to our primary router. Affected file silcd/server.c.
1123 * Fixed silc_server_command_identify_check_client to assemble
1124 correct WHOIS packet. It send corrupted WHOIS packet and
1125 caused problem with router to router connections. Affected
1126 file silcd/command.c.
1128 Fixed also silc_server_command_whois_check the same way
1129 as for the IDENTIFY command.
1131 * Added new SilcIDListStatus to the server in the SilcIDListData
1132 structure. The status now includes the current status of
1133 the entry (like registered, resolved etc.). Affected file
1134 silcd/idlist.[ch]. Defined a bunch of different status types
1135 as well. This replaced the old boolean registered field as well.
1137 Added resolve_cmd_ident field to the SilcClientEntry structure
1138 too so that if the entry is for example being resolved so
1139 another command may attach to the same pending command reply
1140 without requiring to resolve the same entry again. This concept
1141 should optimize the WHOIS and the IDENTIFY resolving under
1142 heavy load by taking away unnecessary resolving for entries
1143 that are being resolved already.
1145 Added support for adding multiple pending commands for one
1146 command idenfier. Affected file silcd/command[_reply].[ch].
1148 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1149 before deleting the data. Otherwise the hash table will have
1150 freed data in comparison functions. Affected file is
1151 silcd/command_reply.c.
1153 * Fixed silc_idlist_replace_client_id to add the new entry to
1154 the cache with NULL nickname. Otherwise there will be invalid
1155 memory as the nickname after the nickname is freed. Affected
1156 file silcd/packet_receive.c.
1158 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1159 saved into wrong slots because the previous number of entries
1160 was not taken into account. Affected file silcd/idlist.c.
1161 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1163 * If we are router and we receive JOIN notify to a channel that
1164 does not have any users then notified client is marked as the
1165 channel founder, as it is it. The affected file is
1166 silcd/packet_receive.c
1168 * Added to the extended hash table API's table_del_*ext functions
1169 the destructor as argument too, so that the caller can decide
1170 which destructor to use or whether to use destructor at all.
1171 Affected file lib/silcutil/silchashtable.[ch].
1173 * Fixed ID Cache purging. It actually deleted the entries from
1174 the hash table after the data was freed. The hash table ended
1175 up comparing freed memory. The affected file is
1176 lib/silccore/silcidcache.c.
1178 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Fixed Irssi SILC client's KILL command's HELP syntax.
1182 * The USERS command now resolves the detailed user information
1183 if the userinfo field is missing. Affected file is
1184 lib/silcclient/command_reply.c.
1186 * Do not print error in silc_file_read if the read file does
1187 not exist. Just silently return NULL. Affected file is
1188 lib/silcutil/silcutil.c.
1190 * Fixed the silc_log_output to not wine about NULL filename
1191 and to not create some bogus " " filename. Affected file is
1192 lib/silcutil/silclog.c.
1194 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Fixed various printing bugs on the user interface in the
1197 Irssi SILC Client. Minor changes that were forgotten from
1200 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Fixed the configure.in.pre and the compilation and distribution
1203 environment to support the new autoconf 2.52. That version is
1204 now required to compile the CVS trunk.
1206 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1209 to generally parse user@fqdn format strings. Affected file
1210 lib/silcutil/silcutil.c.
1212 * Added nickname_format and nickname_force_format fields to the
1213 SilcClientParams structure. The first one defines the format
1214 for the nicknames that the library will enforce if the receives
1215 multiple same nicknames. The second one is boolean value and
1216 can be used to force the library to always enforce the format
1217 to the nicknames regardles whether there are multiple nicknames
1218 or not. This configurable formatting was employed to flexibly
1219 support accessing multiple nicknames from the user interface.
1220 The userinterface can now set the nicknames to what ever format
1221 they prefer. Affected file lib/silcclient/silcapi.h.
1223 Added function silc_client_nickname_format to the file
1224 lib/silcclient/idlist.c. It performs the nickname formatting.
1226 Added new field `hostname´ to the SilcClientEntry context.
1227 It holds the hostname of the client. Affected file is
1228 lib/silcclient/idlist.h.
1230 * Irssi SILC Client sets the nicknames in nick@hostn format.
1231 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1232 irssi/src/silc/core/silc-core.c.
1234 The WHOIS printing now also shows both the real nickname and
1235 the formatted nickname so that user knows how to access the
1236 user if there are multiple same nicknames cached. Affected
1237 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1238 printing formatting too to take the hostname now as a separate
1239 argument. The Affected file is
1240 irssi/src/fe-common/silc/modules-formats.[ch].
1242 * Changed the silc_client_get_clients_local to accept the formatted
1243 nickname as argument. It accepts the real nickname too but the
1244 formatted nickname can be used to find the true entry from
1245 multiple entries. Affected file lib/silcclient/silcapi.h and
1246 lib/silcclient/idlist.c.
1248 * Added nickname_format_parse field to the SilcClientParams.
1249 It is a callback function provided by the application to parse
1250 the nickname out of the formatted nickname string. The library
1251 calls it to get the nickname from the formatted string. Since
1252 the application generally knows better the format of the nickname
1253 string it parses it instead of the library, even though library
1254 encodes the formatted string. If the callback function is not
1255 provided then the library will use the string as is. The
1256 affected file is lib/silcclient/silcapi.h.
1258 * All the nickname strings passed to the client library in
1259 commands are now expected to be formatted nickname strings.
1260 If the command does not support the formatted nickname string
1261 it will assume that the sent string is the actual nickname.
1262 Affected file lib/silcclient/command.c.
1264 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Added public key authentication support to OPER and SILCOPER
1267 commands in the client library. Affected file is
1268 lib/silcclient/command.c.
1270 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Changed the get_auth_methdod client operation to be asynchronous.
1273 It can be async if the application resolves the authentication
1274 method from the server during the negotiation. Added new
1275 SilcGetAuthMeth completion callback that the application will
1276 call after resolving the authentication method.
1278 Added function silc_client_request_authentication_method that
1279 the application can use to resolve the authentication method
1280 from the server. Added also SilcConnectionAuthRequest callback
1281 that the library will call after the server has replied. The
1282 application can call this function if it does not know the
1283 current authentication method.
1285 Affected files are lib/silcclient/client.c and
1286 lib/silcclient/silcapi.h.
1288 * The Irssi SILC client now automatically resolves the authentication
1289 method incase any configuration information is not present (and
1290 currently there never is). The affected file is
1291 irssi/src/silc/core/client_ops.c.
1293 * Fixed public key authentication from the client library.
1294 Affected file lib/silcclient/protocol.c. Changed also the
1295 protocol specification about the public key authentication in
1296 the connection authentication protocol. The actual data to be
1297 signed is now computed with a hash function before signing.
1299 * Fixed the public key authentication from the server as well.
1300 Affected file silcd/protocol.c.
1302 * Removed the mlock()'s from the memory allocation routines.
1303 Affected file lib/silcutil/silcmemory.c. The ./configure does
1304 not check anymore for the mlock(). Affected file is
1307 * Fixed USERS command in server to allow the execution of the
1308 command for private and secret channels if the client sending
1309 the command is on the channel. Affected file silcd/command.c.
1311 * Fixed silc_client_get_clients_local to return the clients
1312 count correctly. It could return wrong value. Affected file
1313 lib/silcclient/idlist.c.
1315 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1318 types. The assembler optimizations seemed not to like 64-bit
1319 data types. The assmebler optimizations thus are now enabled
1320 also for BSD systems as opposed to only enable them for Linux.
1322 * Do not check for threads at all on BSD systems. Affected
1323 file configure.in.pre.
1325 * Removed -n and -h options from the Irssi SILC Client since
1326 they are not used in silc.
1328 * Fixed the prime generation to assure that the first digit
1329 of the generated random number is not zero since our conversion
1330 routines does not like number strings that starts with zero
1331 digit. If zero digit is seen the random number is regenerated.
1332 This caused some corrupted RSA keys when the zero first digit
1333 was met. Affected file lib/silcmath/silcprimegen.c.
1335 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Fixed WIN32 configuration in the ./configure script.
1338 Fixed to include xti.h on environments that has it.
1339 Patches by Carsten Ilchmann and andrew.
1341 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * Changed the silc_id_create_client_id to be collision
1344 resistant. It is now assured that there cannot be created
1345 two same client ID's. I suspect that some weird bugs in
1346 the server were actually caused by duplicate Client IDs.
1347 Affected file silcd/serverid.[ch]. A router receiving
1348 new ID now also assures and informs the sending server
1349 if the ID caused collision.
1351 * Changed the silc_id_create_channel_id to also assure that
1352 there are no collisions.
1354 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Statement about ignoring the Mutual Authentication flag when
1357 performing rekey with PFS was a bit misleading. It is ignored
1358 if it was set in the initial negotiation, it cannot be even
1359 set in the rekey. Fixed in the ke-auth draft. Started the
1360 new versions of the protocol drafts in the doc/.
1362 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Fixed a bug in silc_client_command_identify_save when saving
1365 new channel information. The channel name was no duplicated
1366 and caused crash on exit. Affected file is
1367 lib/silcclient/command_reply.c.
1369 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Fixed the getkey command handling in the server. Send just
1372 empty OK reply to the sender if the key could not be fetched
1373 (but everything else was ok, like the key just was not available).
1374 Changed the public key parameter to optional in the protocol
1375 specs so that empty OK reply can be sent. Affected file
1378 Added a message to Irssi SILC client to tell to user if the
1379 server did not return a public key.
1381 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * Fixed a channel key regeneration bug. It registered new
1384 timeout tasks exponentially until all system resources were
1385 used. Affected file silcd/server.c.
1387 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * Added the SILC Document generator to the scripts/silcdoc.
1390 It can be used to generate the Toolkit Reference Manual out
1391 of the source tree. Internally it will also use the RoboDoc
1392 generator now imported in util/robodoc.
1394 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Added couple of return's in rekey protocol if error orccurred
1397 during the protocol. The execution must be terminated.
1398 Affected file silcd/protocol.c. Also, terminate the protocol
1399 always with timeout.
1401 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * The client's Client ID was created initally from the wrong
1404 nickname (it could have been in format nick@host) in the
1405 silc_server_new_client. Affected file silcd/packet_receive.c
1407 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Added some SILC_LOG_ERROR's to various error conditions
1410 if client could not be added to ID cache. Affected files
1411 silcd/packet_receive.c and silcd/server.c.
1413 * When client's sock->user_data is freed, NULL also the
1414 client->router and client->connection pointers. Added check
1415 for these pointers being NULL to various places around the
1416 code. Affected file silcd/server.c.
1418 * Added client->data.registered == TRUE checks to various
1419 places around the code to assure that unregistered client's
1420 are not handled when it is not allowed. Affected file
1423 * Added `bool registered' fields to all
1424 silc_idlist_[server|client]_get_* routines to indicate whether
1425 the fetched client needs to be registered or not. Affected
1426 file silcd/idlist.[ch].
1428 * Add your own entry as registered to the ID cache in the
1429 server. Affected file server.c.
1431 * Fixed a bug in silc_server_new_server. The SilcServer was
1432 set as the new server's context instead of SilcServerEntry.
1433 This naturally caused some weird bugs.
1435 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Do not delete the channel rekey task when adding it
1438 for in silc_server_create_channel_key.
1440 * Changed the silc_server_create_channel_key to return
1441 TRUE or FALSE to indicate the success of the channel key
1444 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Fixed MSVC++ project files and added missing files to
1447 Makefiles under win32/.
1449 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Do not add TCP_NODELAY flag if the operating system
1452 does not have it defined. Affected files are
1453 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1455 * Fixed buffer overflow from Irssi SILC Client. Affected
1456 file irssi/src/fe-common/core/themes.c.
1458 * Fixed double free in client library in the file
1459 lib/silcclient/client.c when disconnecting from server.
1461 * Applied double free patch from cras to Irssi SILC client.
1462 Affected files irssi/src/core/[modules/expandos].c
1464 * Fixed the disconnection handling to Irssi SILC Client.
1465 The application must call silc_client_close_connection
1466 in ops->connect client operation in case of failure of
1467 the connection. Affected file is
1468 irssi/src/silc/core/client_ops.c.
1470 * Do not set sock->protocol to NULL in the function
1471 silc_client_close_connection after executing the protocol's
1472 final callback since the sock might not be valid anymore.
1473 Affected file lib/silcclient/client.c.
1475 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Do not enable SILC_THREADS if the linking with libpthread
1478 did not happen. Affected file configure.in.pre.
1480 * Added notion to protocol specification that server must
1481 verify the sent authentication payload with CMODE when
1482 setting the channel founder key. Implemented it to the
1483 server. Affected file silcd/command.c.
1485 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Added _EXTRA_DIST SILC distribution variable to the
1488 distributions file. It is used to conditionally add extra
1489 files or directories to the specific distribution. Affected
1490 files ./prepare, Makefile.am.pre and distributions.
1492 Removed the `_' from the start of the distribution names.
1495 * Added README.WIN32 for instructions to compile the Toolkit
1498 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Fixed a double free in disconnection in the server. Affected
1501 file is silcd/server.c.
1503 * Fixed the lib/silcske/groups.c to work now also with GMP
1504 MP library. The string conversion did not work when using
1505 specific base and the base is indicated in the string as well.
1507 * Created win32/ directory which now includes MSVC++ specific
1508 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1509 It will appear only in the toolkit distribution
1511 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Changed the key material distribution function in case when
1514 the hash output is too short. The data is now concatenated
1515 a bit differently than it used to. Made the change to the
1516 SKE protocol specification.
1518 * Added better GMP detection to configure.in.pre. A patch
1521 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Fixed a minor bug in SKE that might cause some problem on
1524 some platforms. Affected file lib/silcske/silcske.c.
1526 * Added the cookie checking for initiator in the SKE. It checks
1527 that the responder returns the sent cookie unmodified. The
1528 affected file is lib/silcske/silcske.c. Added new SKE
1529 error type INVALID_COOKIE that can be sent during the
1530 negotiation. Fixed some memory leaks as well.
1532 * Added the "invalid cookie" error message to Irssi SILC client's
1535 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Added `task_max' field to the SilcClientParams to indicate
1538 the maximum tasks the scheduler can handle. If set to zero,
1539 default values are used. Affected file lib/silcclient/silcapi.h.
1541 * Fixed memory leaks in silc_client_close_connection. Affected
1542 file lib/silcclient/client.c.
1544 * Added silc_client_del_client_entry to client library to free
1545 all memory of given client entry. Affected file is
1546 lib/silcclient/idlist.[ch].
1548 * Added new functions silc_client_del_channel and
1549 silc_client_del_server to delete channel and server entries.
1550 Affected file lib/silcclient/[silcapi.h/idlist.c].
1552 * Removed silc_client_del_client_by_id from silcapi.h.
1554 * Fixed the INFO command to return the server's own info
1555 correctly when querying by Server ID. Affected file is
1558 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Removed the non-blocking settings in WIN32 code in the
1561 silc_sock_[read/write] and added SleepEx instead. Affected
1562 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1563 of input data is now checked with FIONREAD and ioctlsocket.
1565 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Call silc_schedule_task_del_by_context in the
1568 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1569 Affected file lib/silccore/silcprotocol.c.
1571 * Call silc_protocol_cancel for active protocols in the
1572 silc_server_close_connection if the funtion
1573 silc_server_free_sock_user_data has not been called.
1574 Affected file silcd/server.c.
1576 * Generic tasks cannot be deleted using the del_by_fd
1577 task deleting function since generic tasks does not match
1578 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1580 * Added a notion to SILCOPER help file that the SILCOPER works
1581 only on router server, not on normal server.
1583 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Added for WIN32 support for the new scheduler as well.
1586 Affected file lib/silcutil/win32/silcwin32schedule.c.
1588 * Fixed the SHA1 implementation to work on various platforms.
1590 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1593 API. It is part of the scheduler now. Everything else is
1594 as previously but some functions has changed their names.
1595 Checkout the lib/silcutil/silcschedule.h for the interface.
1596 Updated all applications to use the new interface. Affected
1597 files are lib/silcutil/silcschedule.[ch].
1599 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Found a bug in the SKE implementation. The HASH value,
1602 specified by the protocol, was not computed correctly. The
1603 public key of the responder was not added to the computation
1604 even though it is mandatory. Affected file lib/silcske/silcske.c.
1605 This unfortunately causes incompatibilities with older
1606 clients and servers.
1608 * Added WIN32 specific network init and uninit functions:
1609 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1610 the Winsock2. Affected file lib/silcutil/silcnet.h and
1611 lib/silcutil/win32/silcwin32net.c.
1613 * Set the socket always to nonblocking mode on WIN32 after
1614 reading data or writing data. Affected file is
1615 lib/silcutil/win32/silcwin32sockconn.c.
1617 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Fixed various compilation problems under WIN32. Affected
1620 files lib/silcutil/win32/silcwin32thread.c and
1621 lib/silcutil/win32/silcwin32schedule.c.
1623 * Removed all _internal.h #includes from public header
1624 files. Internal headers must never be included from
1627 Removed also the lib/silcske/payload_internal.h file.
1629 * All include files that may be needed (public and some others
1630 included by the public headers) by application developers are
1631 now copied to the ./includes directory. It does not copy any
1632 internal headers. Affected file Makefile.defines.pre and all
1633 Makefile.am's under lib/ and subdirs.
1635 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Do not change the ~/.silc directory's permissions automatically.
1638 Affected file irssi/src/silc/core/clientutil.c.
1640 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Do not cancel the protocol in silc_server_close_connection
1643 it might cause recursion. Now cancelled in the function
1644 silc_server_free_sock_user_data. Affected file silcd/server.c.
1646 * Fixed the silc_server_remove_clients_by_server to regenerate
1647 the channel keys correctly finally. Added also new function
1648 silc_server_remove_clients_channels to actually do it.
1649 Affected file silcd/server.c.
1651 * Fixed the silc_server_new_channel to not crash by giving
1652 wrong router to the new channel. Affected file is
1653 silcd/packet_receive.c.
1655 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1658 which is given as argument to the silc_client_alloc now.
1659 It can be used to configure the client and set various parameters
1660 that affect the function of the client.
1662 * The USERS command in server did not check whether the channel
1663 is private or secret. Affected file silcd/command.c.
1665 * Added new argument to the USERS command in protocol specification.
1666 The USERS command now can take the channel name as argument
1667 as well. Added support for this in client and server and
1668 updated the protocol specs.
1670 * Completed the GETKEY command in client. It can be now used
1671 to fetch also servers public key not only some clients.
1672 Affected files lib/silcclient/command[_reply].c.
1674 * Added silc_client_get_server to return server entry by the
1675 server name. Affected files lib/silcclient/silcapi.h and
1678 * Redefined the IDENTIFY command in protocol specification to be
1679 more generic. It now can be used to query information about
1680 any entity in the SILC Network, including clients, servers and
1681 channels. The query may be based either the entity's name
1682 or the ID. Added support for this in both client and server.
1684 Affected files silcd/command.c and lib/silcclient/command.c
1685 and command_reply.c.
1687 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1688 the _from_client and _from_server functions. Affected file
1691 * Added silc_client_get_channel_by_id_resolve to the file
1692 lib/silcclient/silcapi.h to resolve channel information by
1693 its ID. Added also silc_client_get_channel_by_id that
1694 does not resolve it from the server.
1696 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Added SilcServerEntry context into the client library
1699 to represent one server. The INFO command now allocates
1700 these to save the resolved server info. For now on the
1701 client library will also keep information about servers,
1702 connected and resolved with INFO.
1704 The INFO command now allocates the SilcServerEntry context
1705 and saves the server info there. The COMMAND_REPLY in
1706 the INFO now returns the parameters to application in
1707 same order as defined in the protocol specification.
1709 The entries are cached in the client->server_cache.
1711 * The INFO command is now issued after received the Client ID
1712 from the server. Affected file lib/silcclient/client.c.
1714 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1715 to the application as the mode changer might be server.
1716 It is guaranteed that NULL is not returned anymore to the
1717 application. Affected file lib/silcclient/client_notify.c.
1719 The ID Type is now also passed to the application so that
1720 it can check whether the returned entry is SilcClientEntry
1723 Added new function silc_client_get_server_by_id to return
1724 the server entry by ID. Affected files are the
1725 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1727 * Do not create the channel in the Irssi SILC Client when issuing
1728 the JOIN command but when received the sucessful JOIN command
1729 reply. Otherwise the channel might get created even though we
1730 could not join it. The Affected file is
1731 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1733 * Fixed a channel joining bug in router. The router must also
1734 check the channel modes, invite and ban lists etc. when serving
1735 the JOIN command sent by normal server. Affected file is
1736 silcd/command.c. The router now resolves the client's
1737 information from the server who sent the JOIN command if it
1738 does not know it, and processes the JOIN command only after
1741 * Changed the SilcCommandCb to take new argument; void *context2.
1742 Affected file lib/silccore/silccommand.h
1744 The second argument in the command callbacks in the server now
1745 includes the SilcServerCommandReplyContext if the command was
1746 called as pending command callback from the command reply.
1747 Otherwise it is NULL. When called as pending the status of the
1748 command reply will be checked and if it was erronous the
1749 error will be sent to the original sender of the command.
1750 This way the client always receives the error messages even
1751 though the server was actually the one who received the error
1752 when it resent the command to router, for example. Affected
1753 files silcd/command[_reply].[ch].
1755 * Fixed sending WHOWAS command's error message to client if
1756 the requested client could not be found. It was missing.
1759 * Changed the CMODE and CUMODE commands reply arguments in the
1760 protocol specification. The Channel ID is now sent in both
1761 of the commands to identify the channel. Implemented this
1762 new feature to the client and server. Affected files
1763 lib/silcclient/command_reply.c and silcd/command.c.
1765 * Made better checks for invite and ban lists in the JOIN
1766 command in server. Affected file silcd/command.c.
1768 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * The server now performs the incoming host IP/DNS lookup
1771 using the silc_socket_host_lookup and thus does not block
1772 the server anymore. Affected file silcd/server.c.
1774 * Completed the multi-thread support for SILC Scheduler in
1775 the lib/silcutil/silcschedule.c.
1777 * Fixed the configure.in.pre to detect the pthread correctly
1780 * Fixed a deadlock in silc_task_queue_wakeup in the file
1781 lib/silcutil/silctask.c.
1783 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Added new function silc_schedule_wakeup that is used in
1786 multi-threaded environment to wakeup the main thread's
1787 schduler. It needs to be used when a thread adds a new task
1788 or removes a task from task queues. After waking up, the
1789 scheduler will detect the task queue changes. If threads
1790 support is not compiled in this function has no effect.
1791 Implemented the wakeup mechanism to both Unix and WIN32
1792 systems. Affected files are lib/silcutil/silcschedule.[ch],
1793 lib/silcutil/unix/silcunixschedule.c and the
1794 lib/silcutil/win32/silcwin32schedule.c.
1796 * Added new function silc_task_queue_wakeup to wakeup the
1797 scheduler by the specified task queue. Affected file
1798 lib/silcutil/silctask.[ch].
1800 * The silc_socket_host_lookup_start now wakes up the scheduler
1801 after adding the timeout task. Affected file is
1802 lib/silcutil/silcsockconn.c.
1804 * The silc_socket_host_lookup is synchronous now if the threads
1805 support is not compiled in. However, the callback is still
1806 called asyncronously through the scheduler, anyway. Affected
1807 file lib/silcutil/silcsockconn.c.
1809 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Added new function silc_socket_host_lookup to perform
1812 asynchronous IP and FQDN lookups for the socket connection.
1813 Affected files lib/silcutil/silcsockconn.[ch].
1815 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1817 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1818 that may or may not compile the mutex support in.
1820 Changed the silc_mutex_alloc interface. It allocates the
1821 mutex now to the sent pointer and returns TRUE or FALSE.
1823 Affected file lib/silcutil/silcmutex.h.
1825 * Wrote the SILC Task Queue interface to support multi-threads.
1826 Affected file lib/silcutil/silctask.[ch].
1828 * Wrote the SILC Scheduler to support multi-threads. Affected
1829 file lib/silcutil/silcschedule.c.
1831 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1834 in lib/silcutil/win32/.
1836 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Defined SILC Mutex API and SILC Thread API and implemented
1839 them for Unix. Affected files are
1840 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1841 lib/silcutil/unix/silcunixmutex.c and
1842 lib/silcutil/unix/silcunixthread.c.
1844 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Fixed the silc_server_remove_clients_by_server's channel
1847 key re-generation. The hash table handling was incorrect
1848 and would not work with many channels. Affected file is
1851 * Fixed some memory leaks around the server code.
1853 * Rewrote the silc_server_get_users_on_channel to support IPv6
1854 based Client ID's. Affected file silcd/server.c.
1856 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1857 specification. However, a separate document must be written
1858 to define the detailed signing procedure and the payload
1859 associated with the flag. Defined the flag to the
1860 lib/silccore/silcchannel.h as well.
1862 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Changed the dynamic tables to static size tables in the
1865 lib/silccrypt/silchmac.c.
1867 * Removed GCC dependencies from the code. A patch by cras.
1869 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1871 * Do not show the error "Error receiving packet bla bla"
1872 in server if it really was not an error (-2 means that reading
1873 is pending). Affected file silcd/server.c.
1875 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1877 * Fixed a possible crash in silc_server_remove_clients_by_server
1878 in silcd/server.c. Fixed there also some memory leaks.
1880 * Fixed the silc_idlist_replace_client_id. It could replace
1881 wrong key in the hash table. Affected file silcd/idlist.c.
1883 * Do not check whether there are global users on the channel
1884 if the channel->global_users is FALSE. Affected functions
1885 silc_server_remove_from_one_channel and
1886 silc_server_remove_from_channels in silcd/server.c. Also,
1887 do not check if the removed client is local as we can be
1888 sure that global client was not removed from the channel
1889 and checking for global users is not needed.
1891 * The silc_server_remove_clients_by_server now re-generates
1892 the channel keys correctly for those channels that had
1893 clients removed from them. Affected file silcd/server.c.
1895 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Found the reason of random crashes in the server. We weren't
1898 ignoring the SIGPIPE signal (which can be sent in write())
1899 and it crashed the server. Affected file silcd/silcd.c.
1901 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Assure that sock->user_data is not NULL in the function
1904 silc_server_packet_send in silcd/packet_send.c.
1906 * Disconnect the remote connection if it could not be added
1907 to any ID lists in the server. The affected file is
1910 * Check in silc_server_packet_send[_real/dest] that the
1911 socket is not disconnecting and ignore the data if it is.
1912 Affected file silcd/packet_send.c.
1914 * Define inline to __inline on native WIN32 compilation.
1915 Affected file includes/silcwin32.h.
1917 * Added some explicit type casts for inline code since MSVC
1918 require them. Affected files lib/silcutil/silcbuffer.h,
1919 lib/trq/silcdlist.h and lib/trq/silclist.h.
1921 * Print warning in log files from now on if the packet
1922 decryption fails. Affected file silcd/server.c.
1924 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Changed the `say' client operation's interface to accept
1927 new `type' argument to indicate the type of the message sent
1928 by the library. The application may filter the library's
1929 messages according the type. The affected file is the
1930 lib/silcclient/silcapi.h.
1932 * Added two new functions to lib/silcclient/silcapi.h:
1933 silc_client_del_client and silc_client_del_client_by_id.
1934 Affected file lib/silcclient/idlist.c.
1936 * Moved the clientincludes.h from includes/ to silc/ and
1937 serverincludes.h from includes/ to silcd/.
1939 * The modes for the CMODE and CUMODE are now passed as
1940 uint32 for application with COMMAND_REPLY. The affected
1941 file is lib/silcclient/command_reply.c.
1943 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * /WHOIS without arguments shows client's own information.
1946 Affected file lib/silcclient/command.c.
1948 * Changed PING to not accept any arguments. The specs
1949 says that client can ping only the connected server so
1950 requiring an argument is not needed. Affected file is
1951 lib/silcclient/command.c.
1953 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Fixed a fatal bug in private message sending and reception
1956 encryption and decryption when using private message keys.
1957 The implementation was incorrect and did not follow the
1958 specification. It causd that some of the message were
1959 lost since it did not use the sending and receiving keys
1960 as the protocol suggests. This has been fixed and will cause
1961 incompatibilities with older clients when sending private
1962 message encrypted with private message keys. Affected files
1963 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1964 and various other in Irssi SILC Client.
1966 Added `responder' boolean argument to the functions
1967 silc_client_add_private_message_key[_ske] to indicate when
1968 the key is added as responder or initiator of the key
1971 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Removed the silc_ske_check_version function and created
1974 a SilcSKECheckVersion callback. Added also a function
1975 silc_ske_set_callbacks that is now used to set all SKE
1976 callbacks. The callback functions are not given to
1977 the SKE functions anymore, but this function is used to
1980 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1982 * Added `silc_version' argument to the silc_client_alloc
1983 to define the version of the application for the library.
1984 The library will use the version string to compare it
1985 against the remote host's (usually a server) version
1986 string. Affected file lib/silcclient/silcapi.h
1988 * Added the KE protocol context to Key Agreement context
1989 in client library so that we can abort the SKE if it
1990 is in process when we get timeout. Affected file is
1991 lib/silcclient/client_keyagr.c.
1993 * Do not resolve the client ID forever if it returns in the
1994 first time that such client does not exist. This was done
1995 for example with private message. Affected file is
1996 lib/silcclient/client_prvmsg.c.
1998 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Do not add regex.h for WIN32. The affected file
2001 includes/silcincludes.h.
2003 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2004 not work yet 100%. It generates the DLL's automatically
2005 when compiling with --with-win32 under cygwin.
2007 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * lib/contrib/regex.c is not compiled on WIN32.
2011 * Added silc_net_get_socket_opt function to the
2012 lib/silcutil/silcnet.h.
2014 * Added includes/silcwin32.h for WIN32 specific includes
2017 * Do not use ptime structure or any of the posix process
2018 functions on WIN32 in lib/silccrypt/silrng.c.
2020 * Added silc_gettimeofday to provide generic function
2021 for struct timeval on all platforms. Added the function
2022 to lib/silcutil/silcutil.h.
2024 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2027 library as they clearly belong there. As a plus side we
2028 can make the actual socket connection routines platform
2031 Added also new generic function silc_socket_read and
2032 silc_socket_write (that used to be silc_packet_[read/write].
2033 The implementation of these are platform specific.
2035 * Added WIN32 specific routines of silc_socket_[read/write]
2036 to lib/silcutil/win32/silcwin32sockconn.c.
2038 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Added preliminary support for native WIN32 compilation under
2041 cygwin (using the -mno-cygwin option for GCC) to the
2042 ./configure.in.pre. The --with-win32 now prepares the
2043 compilation for native WIN32.
2045 * Rewrote the SILC Scheduler interface in the file
2046 lib/silcutil/silcschedule.h. The scheduler is now context
2047 based and does not have anymore any global static scheduler.
2048 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2049 and created lib/silcutil/win32 directory for WIN32 based
2052 * Added Unix specific network routines to the
2053 lib/silcutil/unix/silcunixnet.c and the old
2054 lib/silcutil/silcnet.c includes now only generic routines.
2056 Added WIN32 specific network routines to the
2057 lib/silcutil/win32/silcwin32net.c.
2059 * Added Unix specific utility functions from the
2060 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2062 * Added WIN32 SILC Scheduler to the file
2063 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2066 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Do not handle JOIN notify in the server if the target client
2069 is not registered (idata->registered == FALSE). The affected
2070 file is silcd/packet_receive.c.
2072 * Update the nickrec->founder in event_cumode in the Irssi SILC
2073 client. Affected file irssi/src/silc/core/silc-channels.c.
2075 * Fixed the CUMODE_CHANGE notify handling in the server when
2076 server and router are announcing their clients on channels.
2077 Now the mode changes are saved and notified correctly. The
2078 affected file is /silcd/packet_receive.c.
2080 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2081 They really did not replace the cache entry in the ID Cache.
2082 Now they do that. Affected file silcd/idlist.c.
2084 * Fixed the KICK notify handling in the Irssi SILC client to
2085 update the channel records so that the kicked client does not
2086 appear to be on the channel. The affected file is
2087 irssi/src/silc/core/silc-channels.c.
2089 * Always update the conn->current_channel when executing command
2090 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2092 * Fixed the KILL notify handling in Irssi SILC client to remove
2093 the killed client on all channels.
2095 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Fixed the silc_parse_command_line to remove extra spaces
2098 from the start and end of the arguments. Affected file is
2099 lib/silcutil/silcutil.c.
2101 * Cancel and free any active protocol in the function
2102 silc_server_close_connection. Affected file silcd/server.c.
2104 * Cancel and free any active protocol in the function
2105 silc_client_close_connction. Affected file is
2106 lib/silcclient/client.c.
2108 * Do not execute the KILL command for clients that are in
2109 history (ie. they are not in the network). Affected file is
2112 * Fixed KILL notify handling, client does not crash anymore.
2113 Affected file irssi/src/silc/core/silc-channels.c.
2115 * Reduced the default packet buffer size from 2048 to 1024 in
2116 lib/silccore/silcpacket.c.
2118 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2119 counter to the SKE context that is incresed when the SKE library
2120 performs async operation outside the library. If the outside
2121 process frees the SKE context and FREED status will be set
2122 and the library will detect after the sync operation that the
2123 libary is freed. The affected files are
2124 lib/silcske/silcske[_status].[ch].
2126 * Resolve the client entry information in the function
2127 silc_client_channel_message to assure that NULL pointer is not
2128 passed as client entry to the application. */
2130 * Fixed the task timeout calculation to assure that there is
2131 never negative timeouts. The affected file is
2132 lib/silcutil/silcschedule.c.
2134 * Fixed the channel user mode notification sending in server.
2135 It was sent point-to-point to the router (or to server by router)
2136 but it needs to be destined to a channel. The routines now
2137 supports sending the channel user mode notifys to the channels
2138 when announcing clients and channels. Affected files are
2139 silcd/server.c and silcd/packet_receive.c.
2141 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2142 It did not actually replace the old channel entry in the cache.
2143 Affected file lib/silcclient/client_notify.c.
2145 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2147 * Fixed a possible crash in silc_packet_send_prepare. It now
2148 assures always that there is enough space in the buffer and
2149 at the tail area of the buffer (for MAC).
2151 Fixed the inbound buffer reallocation in silc_packet_read.
2152 It was old code and did not handle the reallocation correctly.
2155 The affected file is lib/silccore/silcpacket.c.
2157 * Fixed buffer overflow in silc_parse_nickname in the file
2158 lib/silcutil/silcutil.c.
2160 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * make install generates new server keys only if there is not
2165 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2168 Added check that if the NOREPLY is set then we will not send
2169 the away message. This avoids infinite loop of away messages
2170 if both clients are away. The affected file is
2171 lib/silcclient/client_prvmsg.c.
2173 * Fixed client crash if /NICK was given without arguments.
2174 Affected file lib/silcclient/command.c.
2176 * Server does not send the invite list in INVITE command back
2177 to the client if the list was not altered. Added this notion
2178 to the protocol spec as well. Affected file silcd/command.c.
2180 Fixed possible crash in INVITE command by checking the
2181 value of silc_server_get_client_route command.
2183 * Fixed the INVITE notify type handling. The arguments are now
2184 taken in correct order and client does not crash. The affected
2185 file is irssi/src/silc/core/silc-channels.c.
2187 Removed the "Inviting xxx to channel" message from the
2188 client library away and let the application handle it.
2189 Affected file lib/silcclient/command.c. Added that message
2190 to Irssi SILC client's message formats.
2192 * Fixed CMODE command crash in client. It now checks the
2193 amount of arguments correctly and does not crash. The affected
2194 file is lib/silcclient/command.c.
2196 * Do not create new channel automatically in silc_channels_join
2197 but check whether the channel by that name already exists.
2198 Affected file irssi/silc/core/silc-channels.c.
2200 * Do not send the SERVER_SIGNOFF to router if the disconnected
2201 entity was the router. Affected file silcd/server.c.
2203 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2204 SILC client as it was missing from there.
2206 Added the handling of the KICK notify to the Irssi SILC client
2207 as it was missing. Added "you have been kicked" message to
2208 Irssi SILC client's message modules formats.
2210 Added the handing of the KILL notify to the Irssi SILC client
2211 as it was missing. Added the kill message module formats
2214 The affected file is irssi/src/silc/core/silc-channels.c.
2216 * The router did not save the channel mode the server announced.
2217 Affected file silcd/packet_receive.c.
2219 * Fixed a possible crash in INFO command in server. If the
2220 server did not provide the server info it crashed. Affected
2221 file silcd/command.c.
2223 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * Fixed the GETKEY command in the server to check also the
2226 global list. Otherwise the GETKEY would not work correctly
2227 in normal SILC server. Affected file silcd/command.c.
2229 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Fixed GETKEY crash, it crashed if the command did not succseed.
2233 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2236 is now real and not just an macro interface to GMP.
2238 Removed the entire GMP from the source tree and imported new
2239 NSS MPI library instead. Reason for removing GMP is that it is
2240 extremely large and compiles extremely slow. The NSS MPI
2241 is only a few files and compiles in less than 10 seconds.
2242 The speed is also about the same as GMP. The MPI is imported
2243 to lib/silcmath/mpi.
2245 If the system has GMP installed we will still use the GMP.
2246 If it is not then the NSS MPI will be compiled.
2248 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Merged a long nickname (127 characters long) crash bugfix from
2251 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2253 * Merged a freed memory reference bugfix from Irssi CVS tree.
2254 Affected file irssi/src/core/commands.c.
2256 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2258 * Added the server's public key sving and verification to the
2259 server when performing the SKE. This was missing and the
2260 remote server's (or router's) public key was accepted without
2261 checking whether we have it previously or trust it at all.
2262 Affected file silcd/protocol.c.
2264 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Check in the silc_server_timeout_remote if protocol is active
2267 and make sure that the protocol's final callback is called so
2268 that all memory if freed. Affected file silcd/server.c.
2270 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2272 * silc_server_whois_send_reply crashed the server if the nickname
2273 was 127 characters long. Affected file silcd/command.c.
2275 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Added sanity check to the silc_server_new_client. If the hostname
2278 is provided inside username then check that the provided hostname
2279 really is the same as the resolved one. If the hostname was not
2280 resolved then check it from the public key. Affected file is
2281 silcd/packet_receive.c.
2283 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2284 if the server disconnected us and the connection is not valid
2285 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2287 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2288 the library to the lib/silcutil/silcutil.[ch].
2290 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Close log file after open. Affected file
2293 lib/silcutil/silclog.c.
2295 * Check whether sock == NULL in silc_client_send_packet and return
2296 if it is. Affected file lib/silcclient/silcclient.c.
2298 * Check rec->entry == NULL in the Irssi SILC Client before
2299 sending the channel message. Affecte file is
2300 irssi/src/silc/core/silc-servers.c.
2302 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Merged a splitted window bugfix from Irssi CVS tree. The
2305 affected file is irssi/src/fe-text/textbuffer-view.c.
2307 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2308 It did not print nickname.
2310 * Improved the distributions system a bit.
2312 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2315 irssi/src/fe-text/gui-window.c.
2317 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2318 to in-active server. The affected file is
2319 irssi/src/silc/core/client_ops.c.
2321 * Resolve the client in USERS command reply if the entry does
2322 not have username resolved. The affected file is
2323 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2324 command to WHOIS command to really resolve stuff. The USERS
2325 is not used any more in any critical section so WHOIS can
2326 be used even though it might be slower than IDENTIFY.
2328 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2331 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Changed the protocol API a bit more consistent in the
2334 lib/silccore/silcprotocol.[ch].
2336 * Changed the following headers to ROBODoc format:
2338 lib/silccore/silcpayload.h
2339 lib/silccore/silcprotocol.h
2340 lib/silccore/silcsockconn.h
2342 All core library headers are now formatted.
2344 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2346 * Fixed a bug in Irssi SILC client; do not show that you are
2347 server/router operator if you really are not. Affected file is
2348 irssi/src/silc/core/client_ops.c.
2350 * Renamed silc_command_free_payload to silc_command_payload_free.
2351 Affected file lib/silccore/silccommand.h
2353 * Added silcmath.h to include the prototoypes of various routines
2354 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2357 * Changed the following headers to ROBODoc format:
2359 lib/silccore/silcchannel.h
2360 lib/silccore/silccommand.h
2361 lib/silccore/silcid.h
2362 lib/silccore/silcidcache.h
2363 lib/silccore/silcmode.h
2364 lib/silccore/silcnotify.h
2365 lib/silccore/silcpacket.h
2366 lib/silcmath/silcmath.h
2368 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Added checking to the server code not to start the server if
2371 ciphers and stuff are not configured properly. Affected files
2372 silcd/serverconfig.[h] and silcd/server.c.
2374 * Changed the layout of the header files of the public interfaces
2375 in the SILC libraries. The new layout supports ROBODoc
2376 documentation tool (and some others) so that it is easy to create
2377 a library reference manual. All the other headers and source
2378 code must still follow the CodingStyle document. Also source
2379 code must not include these ROBODoc stuffs, only the headers.
2380 Furthermore, all public interface headers must now be named
2381 by using `silc' prefix, example: silcapi.h, silccipher.h.
2382 Some files were renamed due to this. All the other headers
2383 must not be used as public interfaces. I will update the
2384 CodingStyle document later. Changed following headers, so far:
2386 lib/silcclient/silcapi.h
2387 lib/silccore/silcauth.h
2388 lib/silccore/silcprivate.h
2389 lib/silccrypt/silcdh.h
2391 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Removed silc_client_packet_send_flush from the client library
2396 as it is not needed. Affected file lib/silcclient/client.[ch].
2398 * Added printing of message of unresolved authentication method
2399 to the Irssi SILC client. Added it to the module formats.
2400 Removed the same message from the client library.
2402 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Added new distribution feature, DISTLABEL. Every distribution
2405 can define own preprocessor label that can be used in the
2406 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2407 file distributions, acconfig.h.pre and prepare.
2409 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Added Makefile.defines_int to include the actual definitions
2412 for Makefile.defines.in. Tested the new distribution system,
2413 created distributions and tested installation.
2415 * Added AWAY message printing to the Irssi SILC client. Added
2416 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2418 * Added SCONNECT command to call the SILC's CONNECT command.
2419 Cannot use CONNECT directly since Irssi uses that internally.
2420 Affected file irssi/src/silc/core/silc-servers.c.
2422 Added ACTION local command. It is same as ME command but takes
2423 the channel as mandatory argument.
2425 Rewrote some of the Irssi's help files to suite for SILC
2428 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Added Makefile.defines[.in] that should for now on be included
2431 in all Makefile.am file in the source tree. That file includes
2432 all common compilation definitions for SILC source tree.
2434 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Minor changes to the ./prepare script to change the package
2437 name according the distribution name to the configure.in.
2439 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Created new distribution system. Added file `distributions'
2442 that defines all the distributions that can be created out of
2443 the SILC source tree. The ./prepare script now reads that
2444 file to determine how to prepare the distributions. The
2445 first argument to the ./prepare is the name of the distribution
2446 and second is the version of the distribution. If given
2447 without arguments it creates the default (toolkit) distribution
2448 with the default version (defined in ./prepare).
2450 All Makefile.am files that are subject to the distributions
2451 are now named as Makefile.am.pre. These are ./Makefile.am
2452 and lib/Makefile.am. Others may be changed later.
2454 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Added invite list, ban list, some key management and connection
2457 error message printing to module formats in the Irssi SILC client.
2459 * Added new silc_client_set_away_message to set the away message
2460 that is back to the person who sent private message. The
2461 affected file lib/silcclient/silcapi.h and the
2462 lib/silcclient/client_prvmsg.c.
2464 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Fixed the private message sending in the Irssi SILC client,
2467 added local command KEY to the Irssi SILC client.
2469 Added key management and key agreement message formats to the
2470 irssi/src/fe-common/silc/module-formats.[ch].
2472 Added USERS (alias WHO) printing, server/router operator
2473 indication and LIST command printing to the module formats.
2475 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Fixed channel joining notify handling, cumode notify handling
2478 from Irssi SILC client.
2480 * Added SILC specific module-formats to the Irssi SILC client so
2481 that SILC specific message hilighting, colors etc is possible.
2482 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2484 Added channel mode, channel user mode, actions, notices,
2485 whois and whowas printing to the the module-formats.c.
2487 * Fixed a bug in channel deletion in the server. The channel
2488 is not left to the cache even if the channel founder auth mode
2489 is set when there are no users anymore on the channel. Affected
2490 file silcd/server.c.
2492 * The silc_net_localhost now resolves the entire hostname including
2493 the domain name. Affected file lib/silcutil/silcnet.c.
2495 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Changed the ask_passphrase client operation to be ascynchronous.
2498 It has now a completion callback and a context that the
2499 application must call after it has got the passphrase from
2500 the user. Affected files lib/silcclient/silcapi.h,
2501 lib/silcclient/protocol.c, lib/silcclient/command.c and
2504 Added SilcAskPassphrase callback that the application calls
2505 to deliver the passphrase to the library.
2507 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2508 The public key verification and especially a certificate
2509 verification is asynchronous procedure.
2511 Added new SILC_SKE_STATUS_PENDING status to indicate the
2512 request is pending and a callback will be called to finalize
2515 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2516 indicate that remote end did not send its public key (or
2517 certificate), even though we require it. Added check for this
2518 condition in the SKE. This was a security bug, now fixed.
2520 Defined new SilcSKEVerifyCbCompletion callback that is called
2521 when the verification process is completed.
2523 The affected files lib/silcske/silcske_status.h and
2524 lib/silcske/silcske.[ch].
2526 * Changed the verify_public_key client operation to be async
2527 as well. Defined SilcVerifyPublicKey callback that is used to
2528 indicate the success of the public key verification process.
2530 Changed the server and client to use the new async client
2533 * Changed the Irssi SILC client's internal scheduler to be called
2534 twice as many times as it used to be. As a result the client
2535 should be a bit faster now. Affected file is
2536 irssi/src/silc/core/silc-core.c.
2538 * Added support to Irssi SILC client of asynchronous public key
2539 verification and passphrase inquiry. Affected file is
2540 irssi/src/silc/core/silc-core.c.
2542 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Do not say "You have left channel %s" in client library.
2545 Moved it to the application. Affected files are
2546 lib/silcclient/command.c and silc/client_ops.c.
2548 * Fixed silc_client_get_clients. Command context was not
2549 duplicated and was freed memory in the callback. Affected
2550 file lib/silcclient/idlist.c.
2552 * Do not say "you are now talking..." on JOIN command in the
2553 client library. The appliation must handle it.
2555 * Do not say ".. changed topic to" in command reply in the
2556 client libary. The application must handle it.
2558 * Fixed TOPIC command sending in the client library.
2560 * Fixed a memory leak in silc_client_command_free in the file
2561 lib/silcclient/command.c.
2563 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2565 * Imported a modified version of Irssi client to the source tree.
2566 The Irssi will be used to create a new client called
2567 Irssi SILC. Imported to irssi/.
2569 Added silc_core_init_finish function to the Irssi. Affected
2570 file irssi/configure.in.
2572 A lot changes in the Makefile.ams around the irssi tree.
2574 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Do not rehash if the new size is same as the old size of the
2577 hash table, in the silc_hash_table_rehash*. The affected file
2578 lib/silcutil/silchashtable.c.
2580 * Replaced hash_table_del_by_context calls from the server
2581 (when channel->user_list and client->channels) to the
2582 hash_table_del as it is sufficient and faster.
2584 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Added silc_hash_table_list, silc_hash_table_get and the
2587 SilcHashTableList structure to provide an alternative way to
2588 traverse the hash table. The affected files are
2589 lib/silcutil/silchashtable.[ch].
2591 * Changed the server's idlist routines to use the hash table
2592 routines to optimize the code.
2594 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Replaced the client entry's `channel' list and channel entry's
2597 `user_list' list to hash tables for optimized lookup. Changed
2598 the code to use the hash table interface around the code.
2599 Affected file lib/silcd/idlist.[ch].
2601 * Added `auto_rehash' boolean argument to the function
2602 silc_hash_table_alloc to indicate whether the hash table should
2603 auto-rehash when it thinks is appropriate time. It will
2604 increase the hash table size if the there is twice as much
2605 entries in the table than the size of the table, and will
2606 decrease the size if there are twice as less entries than
2607 the size of the table.
2609 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2613 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * silc_idcache_purge_by_context deletes the entry now by context
2616 as it is supposed to do. Affected file lib/silccore/idcache.c.
2618 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2619 client is not anymore valid (WHOWAS givens the info) and not
2620 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2622 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Removed the `data' and `data_len' arguments from the ID Cache
2625 interfaces and added `name' argument. ID Cache does not handle
2626 anymore the binary data only a names associated with given ID.
2628 * When hashing a Client ID with silc_hash_id the entire ID is
2629 not hashed anymore, instead only the hash of the Client ID is
2630 hashed. This way we can access the Client ID from the cache
2631 with Client ID but with the hash of the ID (which is a hash of
2632 the nickname) as well without any difference in performance.
2634 Added also silc_idcache_find_by_id_one_ext to do one on one
2635 searching when we have the actual ID. Added also function
2636 silc_hash_client_id_compare. The affected files are
2637 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2639 * When hashing the name associated with a ID it is always done
2640 in lowercase. This way we can access the cache without worrying
2641 about case-sensitivity, even though, for example nicknames are
2644 * Fixed a bug in server with channel message sending. It put
2645 wrong ID type as destination ID. The affected file
2646 silcd/packet_send.c.
2648 * silc_idcache_del_by_context now deletes from all hash tables
2649 by context. Affected file lib/silccore/idcache.c.
2651 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Changed the client library to use the new ID Cache interface.
2654 Changes around the source tree.
2656 * Added silc_hash_table_rehash_ext to rehash with specific
2657 hash function. Affected file lib/silcutil/silchashtable.[ch].
2659 * Added silc_hash_string_compare to compare two strings in the
2660 hash table. Affected file lib/silcutil/silcutil.[ch].
2662 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Added new function silc_idcache_del_by_context into the
2665 lib/silccore/idcache.[ch].
2667 * Changed the server's ID list routines to use the new ID Cache
2668 interface. Changes around the source tree.
2670 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Added silc_hash_table_del[_by_context]_ext functions in to the
2673 lib/silcutil/silchashtable.[ch].
2675 Removed silc_hash_table_find_all* routines and added new
2676 silc_hash_table_find_foreach to replace them.
2678 Added silc_hash_table_replace_ext function as extended
2679 replacing function. Separated the simple hash table interface
2680 from the extended hash table interface in the file
2681 lib/silcutil/silchashtable.h.
2683 * Fixed minor bugs and changed it to use some of the new
2684 hash table functions in lib/silccore/idcache.c
2686 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Added new function silc_hash_table_find_all to return all keys
2689 in the hash table by the specified key. As the hash table is
2690 collision resistant it also makes it possible to have several
2691 duplicate keys in the hash table. This function may be used to
2692 find all of the keys from the hash.
2694 Added user_context arguments to the SilcHashFunction,
2695 SilcHashCompare and SilcHashDestructor to deliver user specified
2698 Added new fuctions silc_hash_table_find[_all]_ext to do
2699 extended lookup with specified hash and compare functions and
2700 specified user contexts.
2702 Added new function silc_hash_table_add_ext to add the key
2703 with specified hash function and user context.
2705 Added new function silc_hash_table_foreach to traverse all
2706 entrys in the hash table. Added SilcHashForeach callback
2709 Added new function silc_hash_table_del_by_context to delete
2710 the entry only if the context associated with the key matches.
2712 Affected files are lib/silcutil/silchashtable.[ch].
2714 * Removed silc_hash_[server/client/channel]_id and added just
2715 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2716 silc_hash_id_compare to compare two ID's using as the hash table
2717 comparison function. Added also silc_hash_data to hash
2718 binary data and silc_hash_data_compare to compare it.
2720 * Removed silc_idlist_find_client_by_hash as it is not needed
2721 anymore. Affected file silcd/idlist.[ch].
2723 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2724 to use internally the SilcHashTable. The new ID Cache is a lot
2725 faster than the old one. Some of the ID Cache interface was also
2726 rewritten and obsolete and stupid functions were removed.
2728 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2730 * Added entry_count field to the SilcHashTable to keep the number
2731 of the entries in the table. Implemented the function
2732 silc_hash_table_rehash. Added new function
2733 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2735 Fixed a minor bug in silc_hash_table_free.
2737 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2738 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2739 into the lib/silcutil/silcutil.[ch].
2741 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2743 * Implemented a collision resistant hash table into the
2744 lib/silcutil/silchashtable[ch]. See the header and the source
2745 for the SilcHashTable API.
2747 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Merged dotconf version 1.0.2 into lib/dotconf.
2751 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Do not compile anything in lib/silcsim/* if the SIM support
2754 is not enabled. The tree should now compile without problems
2757 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Compiled the SILC under cygwin. Compiled and tested briefly
2760 without problems. More tests needed. The SIMs didn't compile
2763 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2765 * Fixed possible crash in silc_get_username in the
2766 lib/silcutil/silcutil.c.
2768 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Fixed a va_arg in silc/client_ops.c.
2772 * Oops, RC5 routines were named AES and caused some problems
2773 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2775 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Added new SilcIDIP structure into the lib/silccore/id.h and
2778 replaced the old `ip' fields from all SILC ID's to that type.
2779 This is a step towards IPv6 support.
2781 The silc_id_get_len takes now the ID as an extra argument.
2782 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2783 both IPv4 and IPv6 based ID's.
2785 The affected files are lib/silccore/id.[ch] and other files
2786 around the tree using these routines.
2788 * Removed the ID length arguments in server from various
2789 silc_server_send_notify_* routines -> they are not needed
2792 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Fixed memory leak in silc_encode_pem_file in the file
2795 lib/silcutil/silcutil.c.
2797 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Check minor version as well in the SKE. Affected files are
2800 silcd/protocol.c and lib/silcclient/protocol.c.
2802 * Added --identifier option to the server so that an identifier
2803 can be when creating the public key for the server. Affected
2804 file is silcd/silcd.c.
2806 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2807 lib/silccrypt/silcpkcs.c.
2809 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Register default ciphers and stuff when using -C option with
2812 the server. Affected file sildc/silcd.c.
2814 * Put back the servers public key filename format, it is better
2815 than the new one. For now, the client keys are saved with the
2816 new filename format. The affected file silc/client_ops.c.
2818 * Implemented the Cipher API for the rest of the ciphers that
2819 did not implement it or implemented it the wrong way.
2821 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Register default ciphers and stuff when using the -S option
2824 in the client. Affected file silc/silc.c. Same also when
2825 creating new key pair with -C option.
2827 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Fixed the silc_verify_public_key client operation function to
2830 save the public keys differently. The fingerprint is now
2831 used as filename and not the hostname. This way also the
2832 client keys are saved uniquely and not with hostnames. The
2833 affected file is silc/client_ops.c.
2835 * Trimmed the silc_hash_fingerprint function to remove extra
2836 whitespaces from the end of the fingerprint. The affected
2837 file is lib/silccrypt/silchash.c.
2841 * Added silc_cipher_register_default function to register all
2842 default ciphers. It can be used when configuration files
2843 does not exist and the application does not want any specific
2844 ciphers in any specific order.
2846 The SilcDList is now used as silc_cipher_list dynamically
2847 allocated cipher list. Removed the static list all together
2848 and now all ciphers must be allocated to the dynamic list.
2849 The silc_cipher_alloc routine was changed to check only the
2852 All silc_cipher_* routines that used to return int returns
2855 The affected files lib/silccrypt/silccrypt.[ch].
2857 * The same thing was done to silc_hash_* as for silc_cipher_*
2858 routines. Affected files lib/silccrypt/silchash.[ch].
2860 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2861 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2862 Added also silc_pkcs_[un]register[_default] functions.
2863 Removed the data_context from the PKCS API.
2865 * Added silc_hmac_register_default function to register default
2866 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2867 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2868 to unregister all hmacs at once.
2870 * Register the default ciphers, hash functions, PKCSs and HMACs
2871 if client's configuration file does not exist. The affected
2874 * The client did not load the hash functions from the SIM
2875 modules at all. Added support for this. Affected file is
2876 silc/clientconfig.c.
2878 * When decoding public key with silc_pkcs_public_key_decode, check
2879 the supported algorithm only if PKCS are registered. Affected
2880 file lib/silccrypt/silcpkcs.c. The same was done with the
2881 silc_pkcs_private_key_decode.
2883 * Fixed the SILC List routines to keep the list always in order.
2884 It used to change the list's order when traversing the list but
2885 not it preserves the order. Affected file lib/trq/silclist.h.
2887 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Added the client library to use the SilcSocketConnection's
2890 reference counter (by silc_socket_dup) to prevent the bug that
2891 the socket object may be freed underneath async operation.
2893 * The name resolv library checking fixes in the configure.in.pre.
2896 * Created new version of the protocol drafts for future
2897 development. The -03 drafts are the ones that will be changed
2898 in the trunk now and the -02 will remain as they are.
2900 * Send list of CUMODE notifys to the router when announcing
2901 the channel users to the router. Affected file silcd/server.c.
2902 If the router receiving channel founder CUMODE for a channel
2903 that already has channel founder it will send CUMODE notify
2904 to the sender to remove the channel founder rights from the
2905 announced client. Affected file silcd/packet_receive.c.
2907 * The CUMODE notify may now use Server ID as well as the entity
2908 who changes the mode. Updated protocool specs.
2910 * Updated INSTALL and README files.
2912 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * New web pages in the http://silc.pspt.fi. The pages was
2919 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Implemented the [DenyConnectin] config section in the server.
2922 Added silc_server_config_denied_conn to check whether incoming
2923 connection is denied. Affected file silcd/serverconfig.[ch].
2925 * Do not check the ports when checking the incoming configuration
2926 data if the port is 0, meaning any. Affected file is
2927 silcd/serverconfig.c.
2929 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Fixed buffer overflow in silc_string_compare in the file
2932 lib/silcutil/silcutil.c.
2934 * Fixed double free in silc_server_command_leave in the file
2937 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2939 * Fixed the version checking in the server. Affected file is
2942 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2944 * Fixed the configuration data fetching when accepting new
2945 connections in the server. Affected file silcd/server.c.
2947 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Added `sender_entry' argument to the function
2950 silc_server_packet_relay_to_channel so that we can check
2951 whether some destination actually belongs to the same route
2952 the sender belongs (ie, we must not resend the packet to the
2953 sender). Affected file silcd/packet_send.[ch].
2955 * Added `servername' field to the SilcClientEntry in the server
2956 to hold the name of the server where client is from. Affected
2957 file is silcd/idlist.h.
2959 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Moved the channel message encrypting in the router betwen
2962 router connections from silc_server_channel_message to the
2963 silc_server_packet_relay_to_channel since we want to check
2964 whether we have anybody channel before encrypting anything.
2965 Affected files silcd/packet_[receive/send].c.
2967 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Fixed the [AdminConnection] server config section to support
2970 multiple entries. Affected file silcd/serverconfig.c.
2972 * Added support into the server to check the validity of the
2973 incoming connection before executing any KE or authentication
2976 * The connection configuration is now saved to the KE and
2977 connection auth protocol contexts and not fetched anymore in
2978 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2980 * The local hosts listenning address and port is also resolved
2981 now when starting the server. We want to have the socket object
2982 to include the real address and port for the listener. Added
2983 new function silc_net_check_local_by_sock into the files
2984 lib/silcutil/silcnet.[ch].
2986 * Fixed a broadcast bug in server -> do not broadcast if we
2989 * Fixed a routing bug. Do not route broadcast packets ever.
2990 Broadcast packets must be processed always and not routed since
2991 they may be destined to some other host than yourself and thus
2992 would get routed without no good reason. Affected file is
2995 * Added function silc_server_config_is_primary_route to check
2996 whether primary router connection has been configured (a router
2997 configuration that we are initiating). If there is not, we
2998 will assume that there is only two routers in the SILC network
2999 and we will use the incoming router connection as our primary
3000 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3002 * Changed the order of the broadcasting. Broadcast _after_ the
3003 packet has been processed not before. Affected file is
3006 * Fixed a [ClientConnection] parsing bug. The port was never
3007 parsed correctly thus resulting to port 0. Affected file
3008 silcd/serverconfig.c.
3010 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3011 argument and did not set the broadcast packet flag. Affected
3012 file silcd/packet_send.c. Fixed same bug in the function
3013 silc_server_send_notify as well.
3015 * If we receive NEW_ID packet for our own ID in the server, ignore
3018 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Removed the nickname from the Private Message Payload.
3023 Updated the code and the protocol specs.
3025 * Updated protocol specs for submitting to the IETF.
3027 * Tweaked the Random Number Generator a bit. Affected file
3028 lib/silccrypt/silcrng.c. Exported a new function
3029 silc_rng_[global]_add_noise which can be used to add more
3032 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Do not parse packets with different timeout when protocol
3035 is active -> may cause problem with rekey. Affected file
3038 * When server receives signoff notify it must not create
3039 new channel key if the client is on any channels since the
3040 sender of the signoff notify will create it.
3042 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Added printing of error messages during SKE protocol from the
3045 failure packet sent by server during SKE. Affected file
3048 * Removed the client's failure_callback handling with timeout
3049 and handle it immediately when received.
3051 * The SKE library returned wrong type in SUCCESS and FAILURE
3052 packets. They must be 32 bit MSB not 16 bit MSB.
3054 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Ok, rewrote the logic of the re-key and now it seems to work.
3057 I tested it on high traffic with frequent re-keys without
3058 problems. Added hmac_receive (and renamed hmac to hmac_send)
3059 in SilcClientConnection in lib/silcclient/client.h and
3060 in SilcIDListData in silcd/idlist.h. Also, removed the
3061 SilcPacketParserContext's cipher and hmac fields as they are
3062 not needed anymore and actually caused some problems when
3063 the ciphers and hmac's changed underneath the packet parser.
3065 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * If re-key protocol is active then process the incoming packets
3068 synchronously since we must assure that icoming packets encrypted
3069 with the old key is processed before the new keys is set to
3070 use. This is true other packets than for REKEY packets.
3071 Affected file silcd/server.c. The same was done to client library
3072 as well, affected file lib/silcclient/client.c.
3074 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Fixed bug in client and server to accept the force send if
3077 the packet is send from silc_[server/client]_packet_process
3078 function. Otherwise the packets are never delivered, oops.
3080 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Disable force sending of packets when REKEY protocol is active.
3083 We must assure that no packet is sent directly when rekey is
3084 performed. All packets must be sent through packet queue.
3085 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3086 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3087 function is silc_[server/client]_packet_send_real to check
3090 * Replaced the SIM paths from example config files to
3091 /usr/local/modules. Also, make install creates now
3092 /usr/local/silc/logs directory to hold all the SILC server
3095 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Made the configure.in.pre work on Solaris. Patch by salo.
3099 * Made all ciphers compatible with non-x86 machines. Defined
3100 CBC mode macros into lib/silccrypt/ciphers_def.h.
3102 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Fixed the make install.
3106 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * When MAC computation fails the silc_packet_decrypt returned 0
3109 even though it was supposed to return -1. Fixed this. The
3110 affected file is lib/silccore/silcpacket.c.
3112 * Do not replace the config files in /etc/silc (in make install)
3113 if they already exist. Affected file ./Makefile.am.
3115 * Do not send re-key packets immediately but through packet queue.
3116 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3118 * Changed silc_net_check_host_by_sock to return FALSE if the
3119 IP/DNS could not be resolved. Though, it returns the IP address
3120 now even if it could not resolve it (but returns also FALSE).
3121 Affected file lib/silcutil/silcnet.[ch].
3123 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Added silc_pkcs_decode_identifier to decode the public key's
3126 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3127 Added also silc_pkcs_free_identifier. Added also new context
3128 SilcPublicKeyIdentifier.
3130 * Added -S option to the silc client. It is used to dump the
3131 contents of the specified public key file.
3133 * Changed the PKCS api to return the public key length when
3134 setting the public key.
3136 * Fixed a fatal bug in the public and private key file loading.
3137 Affected file lib/silccrypt/silcpkcs.c.
3139 * Execute the packet parsing for client with zero (0) timeout
3140 if the protocol is active. Affected file silcd/server.c.
3142 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Made the key generation options to the silcd program. Added
3145 -C option, equivalent to client's option.
3147 * Added new [ServerKeys] config section to the server. It
3148 configures the server's public and private key.
3150 * Defined generic Public Key Payload into the protocol
3151 specification to send specific type of public keys and
3154 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3155 public key or certificate.
3157 * Implemented the GETKEY command to the server and to the
3158 client library and on user interface.
3160 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Made preliminary `make install' work.
3164 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Added SilcServerRekey context into silcd/idlist.h.
3168 * Added the PFS support as defined in the specification to the
3169 SKE protocol. Affected files lib/silcske/*.c.
3171 * Added `ske_group' field to the SilcServerRekey context to hold
3172 the number of the SKE group that is used with PFS in re-key.
3173 Affected file silcd/idlist.h.
3175 * Added PFS re-key support to the server. Affected file is
3178 * Added silc_protocol_cancel to cancel execution of the next
3179 state of the protocol. Affected file is
3180 lib/silccore/silcprotocol.[ch].
3182 * Added the re-key support with and without PFS to the client
3183 library. Re-key is performed once in an hour, by default.
3185 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3186 Added silc_client_rekey_callback and silc_client_rekey_final.
3187 Affected files are lib/silcclient/protocol.[ch] and
3188 lib/silcclient/client.[ch].
3190 * Removed the `hmac_key' and `hmac_key_len' fields from the
3191 SilcClientConnection structure; not needed. Affected file is
3192 lib/silcclient/client.h.
3196 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Do not ask whether user wants to use the negotiated private key
3199 for private messages, just use it. Affected file is
3200 silc/local_command.c.
3202 * Added `send_enc_key' and `enc_key_len' fields to the
3203 SilcIDListData structure since they are needed in the re-key
3204 phase. Affected file is silcd/idlist.[ch].
3206 * Implemented the simple re-key protocol into the server.
3207 Affected files silcd/server.c and silcd/protocol.[ch]. The
3208 re-key will be performed once in an hour, by default.
3210 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3211 Added silc_server_rekey, silc_server_rekey_callback and
3212 silc_server_rekey_final.
3214 * Removed Tunneled flag from the protocol. Updated the code
3215 and the specifications.
3217 * Adde `pfs' field to the SilcIDListData to indicate whether
3218 the PFS is to be performed in the re-key. Affected file is
3221 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3224 int64 of at least the xintXX size. If void * is less that 4
3225 bytes uint32 * will be used. Defined bool as boolean.
3227 * Changed _ALL_ unsigned long and unsigned int to uint32,
3228 unsgined short to uint16 in the source tree.
3230 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3231 not handle clients that has entry->data.registered == FALSE.
3232 They are not in the network anymore. Affected file is
3235 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3237 * Implemented the sending of the SERVER_SIGNOFF notify in the
3238 server. Affected file is silcd/server.c.
3240 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3241 Added also silc_notify_payload_encode_args into the
3242 lib/silccore/silcnotify.[ch].
3244 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3245 Affected file silcd/packet_receive.c.
3247 * Implemented the SERVER_SIGNOFF notify handling in the client
3248 library. Affected file lib/silcclient/client_notify.c. Also,
3249 implemnted the printing of the SERVER_SIGNOFF info to the
3250 application. Affected file silc/client_ops.c.
3252 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3253 if the deleting was successful. Affected file silcd/idlist.[ch].
3255 * Added support for public key authentication in the connection
3256 authentication protocol in the client library. Affected file
3257 lib/silcclient/protocol.c.
3259 * Changed the server's silc_idlist_get_clients_by_* interface
3260 to support already allocated array so that new entries may be
3261 added to pre-allocated array. Affected file silcd/idlist.[ch].
3262 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3263 and command replies.
3265 * All command reply functions in the server now calls the
3266 pending command callback even if error occured. This way the
3267 error will be delivered to the client as well. Affected files
3268 silcd/command.c and silcd/command_reply.c.
3270 * Fixed INFO command to return local server's info if no server
3271 was provided. Affected file lib/silcclient/command.c.
3273 * Removed RESTART command for good. Updated the code and the
3276 * Rewrote parts of the task system. It is a bit simpler now.
3277 Removed unsued task priorities. The affected files are
3278 lib/silcutil/silctask.[ch].
3280 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Moved the USERS printing from the library to the application.
3283 Affected files lib/silcclient/command.c and silc/client_ops.c.
3285 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Added channel key re-key support. The re-key is perfomed
3290 only by the router and is done once in an hour. Added `rekey'
3291 field to the SilcChannelEntry in the server. Affected files
3292 silcd/server.c and silcd/idlist.h.
3294 * Added silc_task_unregister_by_context into the file
3295 lib/silcutil/silctask.[ch].
3297 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added SILC_UMODE_GONE mode to indicate when the client is not
3300 present in the SILC network. Added also support to the local
3301 command AWAY that will set this mode. Added support of showing
3302 "xxx is gone" in WHOIS command. The USERS command shows the
3303 gone status as well.
3305 * Fixed setting server and router operator privileges in the
3306 server's UMODE command. Affected file silcd/command.c.
3308 * Merged the SKE KE1 and KE2 payloads into one payload. The
3309 new KE payload is equivalent to the old KE2 payload.
3311 Cleaned up the SKE Start Payload parsing. It now uses the
3312 simple buffer unformatting to do the parsing. A lot faster
3315 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3316 to the SKE that is used to indicate whether both of the SKE
3317 parties should perform authentication. By default only the
3318 responder performs authentication. By setting this flag also
3319 the initiator must do authentication. By default it is unset
3320 since in normal SKE case, client to server connection, only
3321 the responder should do authentication. When doing SKE between
3322 two clients both should perform authentication. Updated the
3323 code and the protocol specs.
3325 * A little fix to IDENTIFY command in the server. Search the
3326 client first by hash not nickname. Affected file is
3329 * Fixed the silc_client_close_connection to support closing
3330 the client to client connections wihtout deleting too much
3331 data. Affected file lib/silcclient/client.c.
3333 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3334 are received if protocol used to be active but is not anymore
3335 the application would crash due to NULL pointer dereference.
3336 Affected files silcd/server.c and lib/silcclient/client.c.
3338 * Added `hash' field to the SilcClientConnection to include
3339 the hash function negotiated in the SKE protocol.
3341 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3342 to set the channel founder authentication data. A client can
3343 claim the founder rights later by providing the authentication
3344 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3345 This way the channel founder can regain the channel founder
3346 privileges even it is left the channel. This works only on
3347 local server and the client must be connected to the same
3348 server to be able to regain the founder rights. Updated the
3349 protocol specs accordingly.
3351 Added support to the CMODE command in the client to set the
3352 founder auth data. Read the README to see how to set it.
3354 Added support to the CUMODE command to claim the founder
3355 rights. Read the README to see how to do it.
3357 Added support for the founder authentication to the Channel
3358 Entry in the server. Affected file silcd/idlist.h.
3360 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3361 server's CMODE command. Affected file silcd/command.c.
3363 * Added the following new functions into lib/silccore/silcauth.[ch]:
3364 silc_auth_get_method and silc_auth_get_data.
3366 * The server now saves the remote hosts public key to the
3367 SilcIDListData pointer. Affected file silcd/protocol.c.
3369 * The normal server now does not remove the channel entry from
3370 the cache if the founder authentication data is set. It used
3371 to remove it if the founder was the last one on the channel on
3372 the server and left the channel. The auth data is saved and
3373 if the channel is re-joined later the old entry is used with
3374 the old auth data. Affected files silcd/command_reply.c and
3377 * Removed the `pkcs' field from the SilcIDListData structure
3378 in the server; it is not used. Affected file silcd/idlist.h.
3380 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Fixed packet processing on slow links. Partial packets were
3383 never re-processed because the incoming data buffer was cleared
3384 by the application. Application must not directly clear the
3385 sock->inbuf, the packet processing routines handle it. Fixed
3386 this in client library and in server.
3388 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Fixed the WHOIS and IDENTIFY send reply function to really
3391 check whether to send list or just one entry. Affected file
3394 * Cleaned up the LEAVE command's channel key distribution. The
3395 affected file silcd/command.c.
3397 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3398 can enforce the channel mode as well. In that case the ID
3399 includes the ID of the server. The code now enforces the
3400 mode change if the router have different mode than the server.
3402 * The notify client operation with CMODE_CHANGE notify can now
3403 return NULL client_entry pointer if the CMODE was not changed
3404 by client. Application must check for this.
3406 * Added <Server ID> argument to INFO command to support server
3407 info fetching by Server ID.
3409 * Added silc_server_announce_get_channel_users to get assembled
3410 packets of channel users of the specified channel. Affected
3411 file silcd/server.[ch].
3413 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3414 was freed underneath the ID Cache.
3416 * Re-announce clients when the server received CHANNEL_CHANGE
3417 notify from the router. Affected file silcd/packet_send.c.
3419 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3422 crashed since it did not handle the fact that there is no cipher
3423 called "3" and didn't check the error condition. Now fixed.
3425 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3426 flag. It can be used to send message requests.
3428 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Implemented the RESTART command in the client.
3432 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3433 notice type messages. Added notice printing to the user
3436 * The channel keys are not re-generated if the channel's mode
3437 is PRIVKEY, ie private key on the channel exists. Affected
3438 files silcd/server.c and silcd/command.c.
3440 * Fixed a little bug in channel message delivery when channel
3441 private keys are set in the server. Affected file is
3442 silcd/packet_send.c.
3444 * Changed the setting on channel->on_channel = TRUE from the
3445 silc_client_save_channel_key to the JOIN command reply. The
3446 key payload is not received if the private channel key is set.
3447 Affected file lib/silcclient/command_reply.c and the
3448 lib/silcclient/client_channel.c.
3450 * When the CMODE_CHANGE notify is sent and the channel private
3451 key mode is removed the channel key must be re-generated in
3452 other cells as well. Added this support for the router in the
3453 silcd/packet_receive.c.
3455 * Added new local command NOTICE to send notice message on
3456 channel. Affected file silc/local_command.[ch].
3458 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added new local command ME to the client. It is used to send
3461 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3462 some action. Affected file silc/local_command.[ch].
3464 * Changed channel_message and private_message client operations
3465 to deliver the message flags to the application. Added also
3466 the `flags' arguments to the silc_client_send_channel_message
3467 and silc_client_send_private_message functions. Affected file
3470 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Redefined the Private Message Payload to support private message
3473 keys and to support the new private message flags. Updated
3474 the protocol specs. Flags makes it possible to have for example
3475 CTCP style messages.
3477 * Added new type SilcPrivateMessagePayload and defined an API
3478 for it in the lib/silcclient/silcprivate.[ch].
3480 * Tested private message private keys successfully. Tested the
3481 private message key set, unset and list commands with the new
3484 * Redefined the Channel Message Payload to include the channel
3485 message flags (equal with private message flags) to support
3486 for example CTCP style messages.
3488 * Defined some of the message (for channel and private message)
3489 flags. Updated the protocol specs and added the flags to the
3490 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3492 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Added SilcKeyAgreementStatus type to the key agreement routines
3495 to indicate the current status and error if one occured.
3496 The status types are defined in the lib/silcclient/silcapi.h.
3498 * Added new local command KEY that is used to set and unset private
3499 keys for channels, set and unset private keys for private messages
3500 with remote clients and to send key agreement requests and
3501 negotiate the key agreement protocol with remote client. The
3502 key agreement is supported only to negotiate private message keys,
3503 it currently cannot be used to negotiate private keys for channels,
3504 as it is not convenient for that purpose.
3506 * Fixed a minor pending callback setting bug in the function
3507 silc_client_get_client_by_id_resolve, now the function works.
3508 Affected file lib/silcclient/idlist.c.
3510 * Added function silc_net_get_local_port to get local bound
3511 port by socket. Added to lib/silcutil/silcnet.[ch].
3513 * Added `sockets' and `sockets_count' fields to the SilcClient
3514 object. They hold the sockets of the listenning sockets in
3515 the client. Listenning sockets may be for example the key
3516 agreement server. Affected file lib/silcclient/client.[ch].
3517 Added functions the silc_client_add_socket and the
3518 silc_client_del_socket. They are exported to the application
3521 * Added ~./silc/clientkeys to support other client's public keys.
3523 * Renamed verify_server_key client operation to verify_public_key
3524 and added one argument to indicate the type of the connection
3525 (server, client etc.).
3527 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Added silc_server_connection_auth_request to handle the
3530 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3531 silcd/packet_receive.[ch].
3533 * Added silc_server_send_connection_auth_request into the
3534 silcd/packet_send.c to send the connection auth request packet.
3536 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3539 * Fixed the public key authentication in responder side in the
3540 server. The `auth_data' pointer includes the SilcPublicKey
3541 not the path to the public key. Affected file silcd/protocol.c.
3543 * Implemented the public key authentication in the initiator side
3544 in the server. Affected file silcd/protocol.c.
3546 * Removed the [RedirectClient] config section from the server
3547 configuration. Is not needed and I don't want to implement it.
3549 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Cleaned up the CMODE command in the server. It now works
3552 correctly and supports all the modes defined in the protocol.
3553 Affected file is silcd/command.c.
3555 * Added `hmac_name' field to the SilcChannelEntry in the server
3556 to hold the default HMAC of the channel. It can be set when
3557 creating the channel (with JOIN command). Affected files
3560 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3561 type to indicate the change of the current cipher and hmac
3562 on the channel. Client can safely ignore the <cipher> argument
3563 (if it chooses to do so) since the CHANNEL_KEY packet will
3564 force the channel key change anyway. The <hmac> argument is
3565 important since the client is responsible of setting the new
3566 HMAC and the hmac key into use.
3568 * Fixed the CMODE command in the client library as well.
3570 * Tested CMODE command in router environment successfully.
3572 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Show the version of the remote client (or server) when connecting
3575 to the server. It is logged to the log file. Affected file
3576 is silcd/protocol.c.
3578 * Fixed the KILLED notify handling in the client library. The
3579 client must be removed from all channels when receiving the
3582 Also, do not remove the client entry when giving the KILL
3583 command but when the KILLED notify is received.
3585 * Removed silc_idlist_find_client_by_nickname from the server.
3586 Not needed anymore. Affected files silcd/idlist.[ch].
3588 * Implemented the CHANNEL_CHANGE notify type handling to the
3589 server. Affected file silcd/server.c.
3593 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Added silc_server_send_notify_invite to send the INVITE
3596 notify between routers.
3598 * Implemented the INVITE command correctly to the server.
3600 * Implemented the INVITE notify type handling in the server.
3602 * Implemented the INVITE command to the client library and on the
3605 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added function silc_server_get_client_resolve to find the
3608 client entry by ID from all ID lists and then resolve it
3609 (using WHOIS) if it cannot be found. Affected file is
3612 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Implemented the BAN command to the client library.
3616 * The JOIN command in the server now checks the invite list
3619 * Changed the silc_command_reply_payload_encode_va and the
3620 silc_command_payload_encode_va to support that if argument is
3621 NULL it ignores and checks the next argument. Affected file
3622 lib/silccore/silccommand.c.
3624 * Added silc_server_send_notify_ban to send the BAN notify
3625 type between routers.
3627 * Chaned the silc_notify_payload_encode to support that if
3628 argument is NULL it ignores and checks the next argument.
3629 Affected file lib/silccore/silcnotify.c.
3631 * Tested ban lists in router environment successfully.
3633 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Implemented BAN command to the server, in silcd/command.[ch].
3637 * Removed the BAN and INVITE_LIST modes from the CMODE command
3640 * Added function silc_string_match to regex match two strings.
3641 Affected files lib/silcutil/silcutil.[ch].
3643 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Redefined parts of the SilcChannelEntry in the server to support
3646 the new ban and invite lists.
3648 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Redefined the INVITE command. The same command can be used to
3651 invite individuals to the channel but also to manage the invite
3652 list of the channel (to add to and remove from the invite list).
3653 Updated the protocol specs.
3655 * Added new command SILC_COMMAND_BAN that can be used to manage
3656 the ban list of the channel. Updated the protocol specs.
3658 * Removed the channel modes: the SILC_CMODE_BAN and the
3659 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3660 in the CMODE command. The equivalent features are now available
3661 using INVITE and BAN commands. Updated the protocol specs.
3663 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3664 in the network about change in the current ban list. The notify
3665 type is not used by the client.
3667 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3668 support the invite lists.
3670 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added new function silc_string_regexify that converts string
3673 including wildcard characters into regex string that can
3674 be used by the GNU regex library. Added into the file
3675 lib/silcutil/silcutil.[ch].
3677 Added silc_string_regex_combine to combine to regex strings
3678 into one so that they can be used as one regex string by
3679 the GNU regex library. Added into the file
3680 lib/silcutil/silcutil.[ch].
3682 Added silc_string_regex_match to match two strings. It returns
3683 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3685 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Imported GNU regex to the soruce tree into lib/contrib.
3688 Fixed some compiler warning from the regex.c.
3690 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Fixed MOTD command in the server to work in router environment.
3694 * Fixed the MOTD command in the client library to support
3695 the server argument in the command.
3697 * Added `nickname_len' argument to the silc_idlist_add_client
3698 in the server, as the `nickname' argument may be binary data
3701 * Added silc_idlist_get_channels to return all channels from
3704 * Implemented LIST command to the server. Affected file is
3707 * Implemented the LIST command to the client library and on the
3710 * Added [<user count>] argument to the LIST command reply.
3711 With private channels the user count is not shown.
3713 * Updated TODO and README.
3715 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * The client entry's data.registered must be TRUE even with
3718 global client entry on global client list. The data.registered
3719 is used to check whether the client is anymore in the network,
3720 for example with WHOWAS command so it must be valid.
3722 * Fixed the WHOWAS command in the server. It now actually works
3723 in router environment. Added function into silcd/command_reply.c
3724 silc_server_command_reply_whowas_save.
3726 * Added silc_idlist_purge function to the silcd/idlist.c
3727 to periodically purge the ID Cache.
3729 * Fixed INFO command in the server. It works now in router
3730 environment. Added <server name> argument to the INFO command
3731 reply. Updated the protocol specs.
3733 * Fixed minor bug in silc_idcache_purge to not purge if the
3734 expire value is zero.
3736 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3737 they were buggy because of the WHOWAS information.
3739 * Fixed local command MSG to handle the async resolving of
3740 the remote client properly. It used to fail the first MSG.
3741 Affected file silc/local_command.c.
3743 * Added `data_len' field to SilcIDCache context.
3745 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Update TODO. Todo in commands in the server.
3749 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3752 used by routers as broadcast packet to inform other routers
3753 about the changed user mode.
3755 Implemented the notify handling in the server. Affected file is
3756 silcd/packet_receive.c. Added the function
3757 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3759 * Added new generic Channel Payload and deprecated the New Channel
3760 Payload. The New Channel Payload is now the generic Channel
3763 * Added new argument `mode' to the silc_server_send_new_channel
3764 as it is required in the Channel Payload now.
3766 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3767 and created a new and real SilChannelPayload to represent the
3768 new generic Channel Payload. Implemented the encode/decode
3769 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3771 * Added silc_server_get_client_channel_list to return the list
3772 of channels the client has joined for WHOIS command reply.
3773 Affected file silcd/server.[ch].
3775 * Implemented the channel list sending in the WHOIS command reply
3776 in server and in the client.
3778 Implemented the channel list displaying on the user interface
3779 as well. Affected file silc/client_ops.c.
3781 * Added silc_channel_payload_parse_list to parse list of Channel
3782 Payloads. It returns SilcDList list of SilcChannelPayloads.
3783 Client for example can use this function to parse the list of
3784 channels it receives in the WHOIS command reply. The caller
3785 must free the list by calling silc_channel_payload_list_free.
3786 Affected files lib/silccore/silcchannel.[ch].
3788 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Added one new argument <user mode> to the WHOIS command reply
3791 to return the mode of the user in SILC. Updated the protocol
3794 Implemented it to the server and client.
3796 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Fixed the mode printing on the user interface on joining.
3799 Affected file silc/client_ops.c.
3801 * Implemented the UMODE command and user modes in general to the
3802 client library and to the user interface.
3804 * Implemented the UMODE command to the server.
3806 * The server now sends UNKNOWN_COMMAND error status if client sends
3807 unknown command. Affected file silcd/command.c.
3809 * All server commands now handle the command identifier the right
3810 way when sending the command reply to the client. The client can
3811 use to identify the command replies with the identifier.
3813 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added silc_server_get_client_route to resolve the route to
3816 the client indicated by the client ID. Affected file is
3819 * Added silc_server_relay_packet as general function to relay
3820 packet to arbitrary destination. This deprecates functions
3821 like _send_private_message_key, _relay_notify etc. Affected
3822 file is silcd/packet_send.[ch].
3824 Removed silc_server_send_key_agreement,
3825 silc_server_send_private_message_key and
3826 silc_server_packet_relay_notify functions from the file
3827 silcd/packet_send.[ch].
3831 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3832 server. Affected file silcd/packet_receive.[ch].
3834 * Implemented the KILL command to the client. Implemented the
3835 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3836 Affected files lib/silcclient/command[_reply].c and
3837 lib/silcclient/client_notify.c. Implemented the KILL notify
3838 printing in the user inteface.
3840 * Fixed a lot silc_parse_nick memory leaks from the client
3841 library in the file lib/silcclient/command.c.
3843 * Changed the silc_server_send_notify_on_channels's `sender'
3844 argument from SilcSocketConnection to SilcClientEntry to
3845 check the sender as entry and not as connection object and not
3846 to send to the client provided as argument. The affected file
3847 is silcd/packet_send.[ch].
3849 * The notify packets that are destined directly to the client used
3850 to not to be processed by the server. Now changed that and the
3851 server processes all notify packets. After relaying the packet
3852 to the client the notify packet is processed in the server.
3854 * The silc_server_free_client_data now checks whether there is
3855 pending outgoing traffic for the client and purges the data to
3856 the network before removing the client entry.
3858 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3861 an client is killed from the SILC Network. Updated the protocol
3864 Added new function silc_server_send_notify_killed to the
3865 silcd/packet_send.[ch].
3867 * Added function silc_server_packet_relay_notify to relay notify
3868 packets that are destined directly to a client. In this case
3869 the server does not process the notify packets but merely relays
3870 it to the client. Affected file silcd/packet_send.[ch].
3872 Added also silc_server_packet_process_relay_notify to check
3873 whereto relay the notify. Affected file is
3874 silcd/packet_receive.[ch].
3876 * Implemented the KILL command to the server.
3880 * Added the backup schema desgined last fall to the protocol
3881 specs for everyone to see. The specification is in the
3882 *-spec-xx.txt draft and the packet type definitions for the
3883 backup routers is in *-pp-xx.txt draft. Thusly, added also
3884 new packet type SILC_PACKET_CELL_ROUTERS.
3886 * A big security problem in the implementation discovered. The
3887 signoff of an client did not cause new channel key generation
3888 which it of course should've done. The channel keys must be
3889 always re-generated when client leaves (or signoffs) the channel.
3890 The silc_server_remove_from_channels funtion now handles
3891 the channel key re-generation.
3893 * Added `sender' argument to the silc_server_send_notify_on_channels
3894 to not to send the client provided as argument. Affected file
3895 silcd/packet_send.[ch].
3897 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Implemented OPER and SILCOPER commands into the server and
3902 * Added silc_auth_verify and silc_auth_verify_data to verify
3903 the authentication directly from the authentication payload.
3904 It supports verifying both passphrase and public key based
3905 authentication. Affected file lib/silccore/silcauth.[ch].
3907 * Added `hash' field to the SilcIDListData structure. It is the
3908 hash negotiated in the SKE protocol. Affected file is
3911 * Slight redesigning of the SilcAuthPayload handling routines.
3912 Do not send SilcPKCS but SilcPublicKey as argument.
3914 * Implemented the public key authentication support to the
3915 serverconfig. The public key is loaded from the provided path
3916 and saved as authentication data to void * pointer. Thus,
3917 changed the unsigned char *auth_data to void *auth_data;
3919 * Fixed SHUTDOWN command to send the reply before the server
3920 is shutdown. :) Affected file silcd/command.c.
3922 * Fixed fatal bug in CONNECT command. The hostname was invalid
3923 memory and server crashed. Affected file silcd/command.c.
3925 * Fixed fatal bug in CLOSE command. The server_entry became
3926 invalid but was referenced later in the command. Affected file
3929 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Fixed fatal bug in failure packet handling. Server ignored
3932 the failure and thus crashed when it came.
3936 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3939 that the command may be executed only once in (about) 2 seconds.
3940 The old SILC_CF_LAG flag is same but allows command bursts up
3941 to five before limiting.
3943 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3944 server code. Various commands now includes the CF_LAG_STRICT
3945 flag to disallow any kind of miss-use of the command.
3947 * Fixed the silc_buffer_unformat to not to allocate any data
3948 if the length of the data is zero. It used to allocate the
3949 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3951 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Changed the format of AdminConnection configuration section
3954 in the server. Added username of the admin to the format.
3955 Affected files silcd/serverconfig.[ch].
3957 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3958 to return admin configuration data by host, username and/or
3961 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Implemented WHOWAS command to the server. Added the functions:
3965 silc_server_command_whowas_parse,
3966 silc_server_command_whowas_send_reply,
3967 silc_server_command_whowas_from_client and
3968 silc_server_command_whowas_from_server
3970 * Added <Client ID> argument to the WHOWAS command reply. Updated
3971 the protocol specs accordingly.
3973 * Implemented WHOWAS command and command_reply to the client
3976 Implemented the WHOWAS printing on the user interface.
3978 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added new argument to the WHOWAS command reply, the real name.
3981 It is an optional argument. Updated the protocol specs.
3983 * Added SilcIDCacheDestructor callback that is registered when
3984 the SilcIDCache is allocated. The callback is called when
3985 an cache entry in the ID Cache expires, or is purged from the
3986 cache. Added into lib/silccore/idcache.[ch].
3988 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3989 to destruct the client entries when the cache entry expires.
3990 Other ID Cache's in server and in the client library ignores
3993 * If the ID Cache entry's `expire' field is zero then the entry
3994 never expires. Added boolean `expire' argument to the
3995 silc_idcache_add function in the lib/silccore/idcache.[ch].
3996 If it is TRUE the default expiry value is used.
3998 * Added silc_server_free_client_data_timeout that is registered
3999 when client disconnects. By default for 5 minutes we preserve
4000 the client entry for history - for WHOWAS command.
4002 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Added support to the server to enforce that commands are not
4005 executed more than once in 2 seconds. If server receives
4006 commands from client more frequently, timeout is registered
4007 to process the commands. Affected file silcd/command.c.
4008 Added new function silc_server_command_process_timeout.
4010 * Changed NICK_NOTIFY handling in client library to check that
4011 if the client's nickname was changed, so there is no need to
4012 resolve anything from the server.
4014 * Removed error printing from the WHOIS and IDENTIFY commands.
4015 If error occurs then it is ignored silently in the client library.
4016 The application, however, may map the received error to
4017 human readable error string. The application currently maps
4018 the NO_SUCH_NICKNAME error to string.
4020 * Made the command status message public to the application. Moved
4021 them from lib/silcclient/command_reply.c to
4022 lib/silcclient/command_reply.h. The application can map the
4023 received command status to the string with the
4024 silc_client_command_status_message function.
4026 * Added check to the server to check that client's ID is same
4027 as the Source ID in the packet the client sent. They must
4030 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Added dist-bzip hook to the Makefile.am to make bzip2
4033 compressed distributions.
4035 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Server now enforces the maximum length for the nickname and
4038 the channel as protocol specification dictates. 128 bytes for
4039 nickname and 256 bytes for channel name.
4041 * Moved the WHOIS printing to the application. The client libary
4042 does not print out the WHOIS information anymore, the application
4043 must do it. Renamed silc_client_command_reply_whois_print to
4044 the silc_client_command_reply_whois_save.
4046 The client's idle time is also sent to the application now, and
4047 the idle is shown on screen.
4049 * Added silc_client_command_reply_identify_save to save the
4050 received IDENTIFY entries.
4052 * Do not check for channel private keys in message sending and
4053 reception if the channel does not have the PRIVKEY mode set.
4054 Affected file lib/silclient/client_channel.c.
4056 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4059 just surfaced after chaning the JOIN procedure.
4061 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Added silc_client_get_clients_by_list to get client entries
4064 from Client ID list, that is returned for example by JOIN
4065 and USERS command replies. The application should use this
4066 function for example when JOIN command reply is received to
4067 resolve the clients already on the channel (library does not
4068 do that anymore as USERS command reply is not used in the JOIN
4069 procedure anymore). Affected files lib/silcclient/silcapi.h and
4070 lib/silcclient/idlist.c.
4072 * JOIN command reply and USERS command reply returns now SilcBuffer
4073 pointers instead of unsigned char pointers when returning
4074 the client list and mode list.
4076 * Added <Client ID> argument to the JOIN command reply, mainly
4077 for the server to identify for which client the command was
4078 originally sent. Updated protocol specs accordingly.
4080 * Added SilcDlist private_key pointer to the SilcChannelEntry
4081 in the client to support the channel private keys. Affected
4082 file is lib/silcclient/idlist.h.
4084 * Added SilcChannelPrivateKey argument to the function
4085 silc_client_send_channel_message so that application can choose
4086 to use specific private ke if it wants to. If it is not provided,
4087 the normal channel key is used, unless private keys are set.
4088 In this case the first (key that was added first) is used
4089 as the encryption key.
4091 * Implemented the support for channel private key handling.
4092 Implemented the following functions:
4094 silc_client_add_channel_private_key,
4095 silc_client_del_channel_private_keys,
4096 silc_client_del_channel_private_key,
4097 silc_client_list_channel_private_keys and
4098 silc_client_free_channel_private_keys
4100 Affected file lib/silcclient/client_channel.c.
4102 * Added the support for the private keys in the channel message
4103 sending and encryption and in the message reception and
4104 decryption. Affected funtions are
4105 silc_client_send_channel_message and silc_client_channel_message.
4107 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Added SKE's key verify callback to the client library's
4110 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4112 * Removed the statement that server (or router) must send USERS
4113 command reply when joining to the channel so that the client
4114 knows who are on the channel. Instead, the client list and
4115 client's mode list is now sent in the JOIN command reply to the
4116 client who joined channel. This is better solution.
4118 * Added function silc_server_get_users_on_channel and function
4119 silc_server_save_users_on_channel to the silcd/server.[ch].
4121 * Removed function silc_server_command_send_users from the
4124 * Do not show topic on the client library anymore. The topic is
4125 sent in the command reply notify to the application and the
4126 application must show the topic now.
4128 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added client searching by nickname hash into the IDENTIFY and
4131 WHOIS commands in the server as they were clearly missing from
4132 them. Affected file is silcd/command.c.
4134 * Fixed a bug in private message receiving in the client library.
4135 The remote ID was freed and it wasn't supposed, now it is
4138 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Minor fix to the channel payload; allocate the data area, as it
4141 needs to be of specific length.
4143 * If the key agreement port is zero then the operating
4144 system will define the bound port. Affected files are
4145 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4147 * Added new function silc_channel_payload_decrypt into the file
4148 lib/silccore/silcchannel.[ch].
4150 * Moved the channel message etc, check from silc_packet_decrypt
4151 to applications. The library calls now a generic
4152 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4153 when the packet is either normal or special. This was done to
4154 allow more wide range of checking that was not allowed when
4155 the code was in library. Now applications can do virtually any
4156 checks to the packet and return to the library the decision how
4157 the packet should be processed. Affected files are
4158 lib/silccore/silcpacket.[ch].
4160 Added silc_server_packet_decrypt_check to the server and
4161 silc_client_packet_decrypt_check to the client library.
4163 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4164 to send with specified source and destination information.
4166 * Channel message delivery between routers was broken after the
4167 channel key distribution was fixed earlier. The channel key
4168 was used be to distributed to other routers as well which is not
4169 allowed by the protocol. Now this is fixed and channel keys
4170 really are cell specific and the channel message delivery between
4171 routers comply with the protocol specification.
4173 * Fixed various commands in server to check also the global list
4174 for the channel entry and not just the local list. The affected
4175 file silcd/command.c.
4177 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Added assert()s to buffer formatting and unformatting routines
4180 to assert (if --enable-debug) when error occurs. Affected
4181 file: lib/silcutil/silcbuffmt.c.
4183 * Changed to auto-reconnect to check whether the remote host is
4184 router and register the re-connect timeout if it is. It used
4185 to check that whether we are normal server, but router must do
4186 auto-reconnect with another router as well. Affected file
4189 * Removed the [<key len>] option from CMODE command as the cipher
4190 name decides the key length, nowadays. See the defined ciphers
4191 from the protocol specification.
4193 * Added [<hmac>] option to the CMODE command to define the HMAC
4194 for the channel. Added SILC_CMODE_HMAC channel mode.
4196 * Added [<hmac>] option for the JOIN command so that user can
4197 select which HMAC is used to compute the MACs of the channel
4200 * Added Hmac field to the Channel Message Payload. The integrity
4201 of plaintext channel messages are now protected by computing
4202 MAC of the message and attaching the MAC to the payload. The
4203 MAC is encrypted. Now, it is clear that this causes some
4204 overhead to the size of the packet but rationale for this is that
4205 now the receiver can verify whether the channel message decrypted
4206 correctly and also when private keys are set for the channel the
4207 receiver can decrypt the packet with several keys and check from
4208 the MAC which key decrypted the message correctly.
4210 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4211 lib/silccrypt/silccipher.[ch].
4213 * Added silc_hash_len to return the digest length into the
4214 lib/silcrypt/silchash.[ch].
4216 * Rewrote parts of Silc Channel Payload interface in the
4217 lib/silccore/silcchannel.[ch]. The encode function now also
4218 encrypts the packet and parse function decrypts it.
4220 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed a minor formatting bug in the SKE's key material processing.
4223 It actually might have processed the keys wrong way resulting
4226 * Redefined the mandatory HMAC algorithms and added new algorithms.
4227 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4228 and hmac-md5 truncated to 96 bits. The mandatory is now
4229 hmac-sha1-96. Rest are optional (including the one that used
4230 to be mandatory). Rationale for this is that the truncated HMAC
4231 length is sufficient from security point of view and can actually
4232 make the attack against the HMAC harder. Also, the truncated
4233 HMAC causes less overhead to the packets. See the RFC2104 for
4236 * Added new [hmac] configuration section. The SKE used to use
4237 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4238 is of course wrong. The official names that must be proposed in
4239 the SKE are the ones defined in the protocol specification
4240 (hmac-sha1-96 for example). The user can configure any hmac
4241 using any hash function configured in the [hash] section. At
4242 least, the mandatory must be configured.
4244 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4246 * Added HMAC list to the SKE proposal list. It has now both
4247 hash algorithm list and HMAC list. This makes the protocol
4248 incompatible with previous versions. The SKE now seems to work
4249 the way it is supposed to work, for the first time actually.
4251 * Defined plain Hash algorithms to the protocol specification.
4254 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Implemented support for key agreement packets into the server.
4257 Added functions silc_server_key_agreement and
4258 silc_server_send_key_agreement. Other than these functions,
4259 server has nothing to do with this packet.
4261 * Added support for private message key packets into the server.
4262 Added functions silc_server_private_message_key and
4263 silc_server_send_private_message_key.
4267 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4268 called in the protocol's final callback instead in the END
4269 protocol state. This makes a little more sense and in the same
4270 time in client we can use the same protocol routines for normal
4271 key exchange and to key agreement packet handling as well.
4273 * Added to both client's and server's KE protocol context the
4274 SilcSKEKeyMaterial pointer to save the key material. We will
4275 bring the key material to the protocol's final callback by doing
4276 this. The final callback must free the key material.
4278 * Added SKE's packet_send callback into client's KE protocol
4279 context so that the caller can choose what packet sending function
4280 is used. This way we can use different packet sending when
4281 doing normal SKE when doing key agreement packet handling (in
4282 the key agreement packet handling we do not want to encrypt
4285 * Implemented the responder side of the key agreement routines
4286 in the client. The client can now bind to specified port and
4287 accept incoming key negotiation. The key material is passed
4288 to the application after the protocol is over.
4290 * Implemented the processing of incoming Key Agreement packet
4291 in the client. Added function silc_client_key_agreement to
4294 * Implemented the intiator side of the key agreement routines
4295 in the client. The client can now initiate key agreement with
4296 another remote client. The key material is passed to the
4297 application after the protocol is over.
4299 * Created client_keyagr.c to include all the key agreement
4302 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4303 SILC_TASK_CALLBACK except that it is not static.
4305 * Created client_notify.c and moved the Notify packet handling
4306 from the client.[ch] into that file.
4308 * Created client_prvmsg.c and moved all private message and
4309 private message key routines from the client.[ch] into that file.
4311 * Create client_channel.c and moved all channel message and
4312 channel private key routines from the client.[ch] into that file.
4314 * Changed silc_client_get_client_by_id_resolve to resolve with
4315 WHOIS command instead of IDENTIFY command, in the file
4316 lib/silclient/idlist.c.
4318 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Implemented the SKE's responder side to the Client library.
4322 * When FAILURE is received to the protocol do not trust it
4323 blindly. Register a timeout to wait whether the remote closes
4324 the connection as it should do it, only after that process the
4325 actual failure. This was changed to both client and server.
4327 * Added client_internal.h to include some of the structures
4328 there instead of client.h in lib/silcclient/.
4330 * Added function silc_task_unregister_by_callback to unregister
4331 timeouts by the callback function.
4333 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Some "Incomplete WHOIS info" errors has been appearing on the
4336 log files. Took away the entry->userinfo check from WHOIS
4337 reply sending. The entry->userinfo is now " " if client did not
4338 provide one. I thought this was fixed earlier but something
4339 is wrong still. Let's see if the error still appears.
4341 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Fixed a minor bug in the login when the channel key is
4344 re-generated in the server. It used to generate the key in
4345 wrong order and thus caused problems in the channel traffic.
4347 * Fixed a minor bug in channel key distsribution after
4348 KICK command. The key was not sent to the router even though
4351 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Added silc_ske_process_key_material_data as generic routine
4354 to process any key material as the SILC protocol dictates. The
4355 function is used by the actual SKE library but can be used by
4356 applications as well. This relates to the private message keys
4357 and the channel private keys since they must be processed the
4358 same way the normal SILC session keys. The protocol dictates
4359 this. Affected files: lib/silcske/silcske.[ch].
4361 Added also silc_ske_free_key_material to free the
4362 SilcSKEKeyMaterial structure.
4364 * Defined silc_cipher_set_key function to set the key for
4365 cipher without using the object's method function. The affected
4366 files: lib/silccrypt/silccipher.[ch].
4368 * Implemented silc silc_client_add_private_message_key,
4369 silc_client_add_private_message_key_ske,
4370 silc_client_del_private_message_key,
4371 silc_client_list_private_message_keys and
4372 silc_client_free_private_message_keys functions in the
4375 Added functions silc_client_send_private_message_key to send
4376 the Private Message Key payload and silc_client_private_message_key
4377 to handle incoming Private Message Key payload.
4379 * Added Cipher field to the Private Message Key payload to set
4380 the cipher to be used. If ignored, the default cipher defined
4381 in the SILC protocol (aes-256-cbc) is used.
4383 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Removed lib/silcclient/ops.h file.
4387 Redefined parts of the SILC Client Library API. Created new
4388 file silcapi.h that deprecates the ops.h file and defines the
4389 published Client Library API. Defined also private message key
4390 API and channel private key API into the file.
4392 This is the file that the application must include from the
4393 SILC Client Library. Other files need not be included by
4394 the application anymore.
4396 * Added new key_agreement client operation callback and also
4397 defined the Key Agreement library API for the application.
4399 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4402 is used by clients to request key negotiation between another
4403 client in the SILC network. If the negotiation is started it
4404 is performed using the SKE protocol. The result of the
4405 negotiation, the secret key material, can be used for example
4406 as private message key.
4408 Implemented the Key Agreement payload into the files
4409 lib/silccore/silauth.[ch].
4411 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Redefined ciphers for the SILC protocol. Added some new ciphers
4414 and defined the key lengths for the algorithms. Changed the
4415 code accordingly. The default key length is now 256 bits.
4417 * Fixed SKE key distribution function silc_ske_process_key_material
4418 when the key length is more than 128 bits. The default key
4419 length in SILC is now 256 bits.
4421 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4422 to indicate unsupported algorithm.
4424 * Renamed rijndael.c to aes.c and all functions as well.
4426 * Fixed a long standing channel key setting bug in client library.
4427 Weird that it has never surfaced before.
4429 * Fixed bug in channel deletion. If the entire channel is removed
4430 then it must also delete the references of the channel entry
4431 from the client's channel list as the client's channel entry and
4432 the channel's client entry share same memory.
4434 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Implemented CONNECT and SHUTDOWN commands in the client.
4438 * Implemented CLOSE command to the client.
4440 * Added the function silc_idlist_find_server_by_name into the
4441 files silcd/idlist.[ch].
4443 Added the function silc_idlist_find_server_by_conn into the
4444 files silcd/idlist.[ch].
4446 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * DIE command was renamed to SHUTDOWN. Updated the both code
4451 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4452 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4454 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4457 * Added function silc_server_create_connection function to create
4458 connection to remote router. My server implementation actually
4459 does not allow router to connect to normal server (it expects
4460 that normal server always initiates the connection to the router)
4461 so the CONNECT command is only good for connecting to another
4464 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4467 or some other client was kicked from the channel.
4469 Implemented the handling of the notify type to both client
4472 Implemented silc_server_send_notify_kicked to send the KICKED
4473 notify. It is used to send it to the server's primary router.
4475 * Implemented the KICK command into server and client.
4477 * Added `query' argument to the silc_idlist_get_client function
4478 to indicate whether to query the client from server or not if
4481 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4482 to indicate that the client is not channel founder.
4486 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4488 * Removed the rng context from SilcPacketContext structure and
4489 changed that the packet routine uses the Global RNG API.
4491 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Added support for quit message that client can "leave" on the
4494 channel when it quits the SILC. It is ditributed inside the
4495 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4497 Added silc_server_free_client_data that will take the
4498 signoff message as argument.
4500 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4502 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Updated parts of the protocol specification to keep it up
4507 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4510 payloads in one packet.
4512 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4513 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4514 use now the new List flag.
4516 * Also deprecated the following packet types: REPLACE_ID,
4517 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4519 * Added list support for Notify packet in server.
4521 * Added silc_server_send_notify_channel_change to send the
4522 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4523 the silc_server_send_replace_id.
4525 * Added silc_server_send_notify_nick_change to send the
4526 NICK_CHANGE notify type. Deprecates the function
4527 silc_server_send_replace_id.
4529 * Added silc_server_send_notify_join to send the JOIN notify type.
4530 Deprecates the function silc_server_send_new_channel_user.
4532 * Added silc_server_send_notify_leave to send LEAVE notify type.
4533 Deprecates the function silc_server_send_remove_channel_user.
4535 * Added silc_server_send_notify_cmode and
4536 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4537 types. Deprecates the silc_server_send_set_mode function.
4539 * Added SERVER_SIGNOFF notify type to indicate that server has
4540 quit. This means that all clients on the channel from that
4541 server will drop. This can be also used when netsplit happens.
4543 Deprecated REMOVE_ID packet type since it is not needed anymore
4546 Added silc_server_send_notify_server_signoff to send the
4547 SERVER_SIGNOFF notify type. Deprecates the function
4548 silc_server_send_remove_id.
4550 Added also silc_server_send_notify_signoff to send the
4551 SIGNOFF notify type.
4553 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4554 SILC protocol from this day on. Changed the protocol
4555 specification as well.
4557 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4558 notify type. It is used between routers to notify about
4559 topic changes on a channel.
4561 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4564 * Partly updated the protocol specification to comply with the
4565 changes now made. It is still though a bit outdated.
4567 * The JOIN notify type now takes one extra argument <Channel ID>.
4568 The packet used to be destined to the channel but now the
4569 JOIN type may be sent as list thus it is impossible to
4570 destine it to any specific channel. By adding this argument
4571 it is again possible.
4573 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added CREDITS file. The CHANGES and CREDITS file will appear
4576 in the distribution as well.
4578 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4581 types in the server's silcd/packet_receive.c.
4583 * Implemented CMODE and CUMODE to work in router environment.
4585 * Fixed minor encoding and decoding buglet from the
4586 lib/silccore/silcmode.c.
4588 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4591 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4593 * Changed all SilcConfigServer* and silc_config_server* to
4594 SilcServerConfig* and silc_server_config*, respectively.
4597 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Associated the ID (client or server ID) to the Authentication
4600 Payload to avoid any possibility of forging. Updated the
4601 protocol specification and the code accordingly.
4603 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * The RSA key length is now save to the RsaKey context in the
4606 key generation process in lib/silccrypt/rsa.c. The key length
4607 is now used to figure out the maximum size of the block allowed
4608 to be encrypted/signed.
4610 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4611 is equivalent to the silc_mp_mp2bin but does not allocate any
4614 * Changed silc_mp_mp2bin API to take length argument. If it is
4615 non-zero then the buffer is allocated that large. If zero, then
4616 the size is approximated using silc_mp_sizeinbase, which however
4619 * Created Global RNG API which is global RNG that application can
4620 initialize. After initializing, any routine anywhere in the
4621 code (including library) can use RNG without allocating a new
4622 RNG object. This was done to allow this sort of use of the
4623 RNG in code that has no chance to allocate RNG object. All
4624 applications currently allocate this and many routines in the
4625 library use this. Affected file lib/silccrypt/silcrng.[ch].
4627 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4628 it to use the Global RNG API.
4630 * Defined Authentication Payload into protocol specification that
4631 is used during SILC session to authenticate entities. It is
4632 used for example by client to authenticate itself to the server
4633 to obtain server operator privileges.
4635 Implemented this payload into the lib/silccore/silcauth.[ch].
4636 Implemented also routines for public key based authentication
4637 as the new protocol specification dictates.
4639 Moved definitions of different authentication methods from
4640 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4642 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4643 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4644 silc_pkcs_verify_with_hash functions into the file
4645 lib/silccrypt/silcpkcs.[ch].
4647 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * The client entry's userinfo pointer must be always valid.
4650 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4651 will fail since it requires the userinfo. Now, the userinfo
4652 is allocated as "" if actual userinfo does not exist. Actually,
4653 it must exist and it is totally Ok to drop client connections
4654 that does not announce the userinfo. However, we will make
4655 this workaround for now.
4657 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4658 to return the remote port by socket.
4660 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4663 SILC_SERVER_PENDING_EXEC and added an new macro
4664 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4665 data or when error occurs while processing the pending command.
4667 Added new argument `destructor' into silc_server_command_pending
4668 and to the SilcServerCommandPending object. This destructor is
4669 now called after calling the pending callback or if error occurs
4670 immediately. If error occurs the actual pending callback won't
4671 be called at all - only the destructor. The destructor may be
4672 NULL if destructor is not needed.
4674 All this applies for client library code as well. Similar
4675 changes were made there as well for the pending commands.
4677 In the client, the application must now allocate the
4678 SilcClientCommandContext with the silc_client_command_alloc
4681 * Added reference counter to the SilcServerCommandContext. Added
4682 function silc_server_command_alloc and silc_server_command_dup
4685 Same type of functions added to the client library for the same
4688 * Removed the cmd_ident from IDListData away since it is now
4689 global for all connections. It is the command identifier used
4690 in command sending and with pending commands. The affected file
4693 * Added reference counter to the SilcSocketConnection objecet to
4694 indicate the usage count of the object. The object won't be
4695 freed untill the reference counter hits zero. Currently only
4696 server uses this, and client ignores it. The client must be
4697 set to use this too later. The affected files are
4698 lib/silccore/silcsockconn.[ch]. Added also the function
4699 silc_socket_dup to increase the reference counter.
4701 This was mainly added because it is possible that the socket
4702 is removed underneath of pending command or other async
4703 operation. Now it won't be free'd and proper DISCONNECTING
4704 flags, etc. can be set to avoid sending data to connection that
4705 is not valid anymore.
4707 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4708 the connection. After that it sets SILC_SET_DISCONNECTED.
4709 It is, however, possible that the socket data is not still freed.
4710 The silc_server_packet_process now checks that data is not
4711 read or written to connection that is DISCONNECTED. The socket
4712 get's freed when the reference counter hits zero.
4714 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Changed the client operation API: channel_message operation's
4717 `sender' is now the client entry of the sender, not the nickname
4718 and the `channel' is the channel entry, not the channel name.
4720 In the private_message operation the `sender' is now also the
4721 client entry of the sender not the nickname.
4723 Affected file is lib/silcclient/ops.h and all applications
4724 using the client operations.
4726 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Moved the calling of ops->connect() from connect_to_server_final
4729 into receive_new_id functin since that is the point when the
4730 client is actually allowed to send traffic to network. The
4731 affected file is lib/silcclient/client.c.
4733 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4736 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4737 (if needs broadcasting) instead of broadcasting the packets one
4738 by one which would make a burst in the network traffic.
4740 * Added `broadcast' argument to the functions in silcd/server.[ch]
4741 silc_server_create_new_channel[_with_id] to indicate whether
4742 to send New Channel packet to primary router.
4744 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Added new function into the silcd/server.[ch] files:
4747 silc_server_create_new_channel_with_id to create new channel with
4748 already existing Channel ID.
4750 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4751 lib/silccore/silcpacket.h. This packet is used t send list of
4752 Set Mode payloads inside one packet. Server uses this to set
4753 the modes for the channels and clients on those channels, that it
4754 announced to the router when it connected to it. The protocol
4755 specification has been updated accordingly.
4757 * The silc_server_new_channel did not handle the packet coming
4758 from normal server as it normally does not send that. However,
4759 when it announces its channels it does send it. Implemented
4760 the support for that.
4762 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4763 into the file lib/silccore/id.h.
4765 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Fixed memory leaks in the functions silc_idlist_del_client,
4768 silc_idlist_del_channel and silc_idlist_del_server in the file
4769 silcd/idlist.c. All of those leaked like a sieve.
4771 * Fixed some small memory leaks in the client's function
4772 silc_client_notify_by_server.
4774 * Added functions into silcd/server.c: silc_server_announce_clients,
4775 silc_server_announce_channels and silc_server_announce_server.
4776 These functions are used by normal and router server to announce
4777 to its primary router about clients, channels and servers (when
4778 router) that we own. This is done after we've connected to the
4781 These functions effectively implements the following packet types:
4782 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4783 and SILC_PACKET_NEW_ID_LIST.
4785 * Added new functions into the silcd/packet_receive.[ch]:
4786 silc_server_new_id_list, silc_server_new_channel_list and
4787 silc_server_new_channel_user_list to handle the incoming
4788 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4790 * Added support of changing Channel ID in the function
4791 silc_server_replace_id. If the server that announces a channel
4792 to the router already exists in the router (with same name but
4793 with different Channel ID), router is responsible to send
4794 Replace ID packet to the server and force the server to change
4795 the Channel ID to the one router has.
4797 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4798 client that the Channel ID has been changed by the router. The
4799 normal server sends this to the client. Client must start using
4800 the new Channel ID as the channel's ID.
4802 Implemented handling of this new type into lib/silcclient/client.c
4803 into the function silc_client_notify_by_server.
4805 * Added new function silc_idlist_replace_channel_id into the files
4806 silcd/idlist.[ch] to replace the Channel ID.
4808 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Call silc_server_command_identify_check always when processing
4811 the IDENTIFY command in silcd/command.c
4813 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4816 send keepalive packets. The packet can be sent by clients,
4817 servers and routers.
4819 Added function silc_socket_set_heartbeat into the file
4820 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4821 If not set, the heartbeat is not performed. The actual
4822 heartbeat is implemented in the low level socket connection
4823 library. However, application is responsible of actually
4826 Added silc_server_send_heartbeat to send the actual heartbeat
4827 packet into silcd/packet_send.[ch]. Server now performs
4828 keepalive with all connections.
4830 * Added silc_task_get_first function into lib/silcutil/silctask.c
4831 to return the timeout task with shortest timeout. There was a bug
4832 in task unregistration that caused problems. TODO has been
4833 updated to include that task system must be rewritten.
4835 * The client library will now resolve the client information when
4836 receiving JOIN notify from server for client that we know but
4837 have incomplete information.
4839 * Rewrote parts of silc_server_remove_from_channels and
4840 silc_server_remove_from_one_channel as they did not remove the
4841 channel in some circumstances even though they should've.
4843 * Encryption problem encountered in server:
4845 The LEAVE command used to send the Channel Key packet to the
4846 router immediately after generating it. However, the code
4847 had earlier sent Remove Channel user packet but not immediately,
4848 ie. it was put to queue. The order of packets in the router
4849 was that Channel Key packet was first and Remove Channel User
4850 packet was second, even though they were encrypted in the
4851 reverse order. For this reason, MAC check failed. Now, this
4852 is fixed by not sending the Channel Key packet immediately but
4853 putting it to queue. However, this is more fundamental problem:
4854 packets that are in queue should actually not be encrypted
4855 because packets that are sent immediately gets encrypted
4856 actually with wrong IV (and thus MAC check fails). So, packets
4857 that are in queue should be encrypted when they are sent to
4858 the wire and not when they put to the queue.
4860 However, the problem is that the current system has not been
4861 designed to work that way. Instead, the packet is encrypted
4862 as soon as possible and left to the queue. The queue is then
4863 just purged into wire. There won't be any fixes for this
4864 any time soon. So, the current semantic for packet sending
4867 o If you send packet to remote host and do not force the send
4868 (the packet will be in queue) then all subsequent packets to the
4869 same remote host must also be put to the queue. Only after the
4870 queue has been purged is it safe again to force the packet
4873 o If you send all packets immediately then it safe to send
4874 any of subsequent packets through the queue, however, after
4875 the first packet is put to queue then any subsequent packets
4876 must also be put to the queue.
4878 Follow these rules and everything works fine.
4880 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added new function silc_server_remove_clients_by_server to
4883 remove all client entries from ID list when the server connection
4884 is lost. In this case it is also important to invalidate all
4885 client entires as they hold the invalid server entry. This
4886 fixes fatal bug when server has lost connection and will reconnect
4889 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Made some sanity checks to silc_server_daemonise like to check
4892 whether the requested user and group actually exists.
4894 * Added sanity check to SKE's silc_ske_responder_finish to check
4895 that the public and private key actually is valid.
4897 * Invalidate the client's nickname when receiving Replace ID
4898 packet and the Client ID is being replaced. This means that the
4899 server will query the nickname if someone needs it (client)
4902 * Sort the ID Cache in client library when the ID Cache data
4903 has changed (needs sorting).
4905 * Do not allow for SILC client to create several connections to
4906 several servers. The client does not support windows right now
4907 and generating multiple connections causes weird behaviour.
4909 Irssi-silc client does support windows and can handle several
4910 connections without problems, see: www.irssi.org and SILC plugin.
4912 * Fixed some places where client was added to the IDList. The
4913 rule of thumb is following (in order to get everything right):
4914 If the client is directly connected local client then the
4915 `connection' argument must be set and `router' argument must be
4916 NULL to silc_idlist_add_client function. If the client is not
4917 directly connected client then the `router' argument must
4918 bet set and the `connection' argument must be NULL to the
4919 silc_idlist_add_client function.
4921 * The funtion silc_server_packet_send_local_channel actually did
4922 not check whether the client was locally connected or not. It
4923 does that now. Fixed a bug related to LEAVE command.
4925 * Fixed Remove Channel User payload parsing bug in server's
4926 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4928 * The server's silc_server_save_channel_key now checks also the
4929 global ID list for the channel as it might not be in the local
4930 list. Fixed a bug related to LEAVE command.
4932 * Is this the end of the [<unknown>] buglet that has been lurking
4933 around for a long time? A little for loop fix in server's
4934 silc_server_command_whois_parse that is used by both IDENTIFY
4935 and WHOIS command. At least, this was a clear bug and a cause
4936 of one type of [<unknown>] buglet.
4938 * WHOIS and IDENTIFY commands call the function
4939 silc_server_command_[whois/identify]_check function even if
4940 we are not router server.
4942 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Added --with-gmp configuration option. If set the GMP
4945 is always compiled in the SILC source tree. If not set then
4946 it is checked whether the system has the GMP3 installed. If
4947 it has then the GMP won't be compiled (the system's headers
4948 and library is used), if it doesn't have it then the GMP is
4949 compiled in the SILC source tree.
4951 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Changed RSA private exponent generation to what PKCS #1
4954 suggests. We try to find the smallest possible d by doing
4955 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4956 not security fix but optimization.
4958 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Added new config entry [Identity] to fork the server and run
4961 it as specific user and group. A patch from Bostik.
4963 * Imported Dotconf configuration library into lib/dotconf.
4964 This will be used to create the SILC configuration files later.
4965 It will appear in the distsribution after this commit.
4967 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * A big code auditing weekend happening. Auditing code for
4970 obvious mistakes, bugs and errors. Also, removing any code
4973 Removed files for being obsolete:
4975 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4976 inline in the file lib/silcutil/silcbuffer.h)
4978 o lib/silcutil/silcbufutil.c (the header has inline versions)
4980 Changed code to fix possible error conditions:
4982 o The buffer formatting routines now check that the destination
4983 buffer really has enough space to add the data. This applies for
4984 both buffer formatting and unformatting
4985 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4986 unformatting was changed to accomodate following rules:
4987 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4988 sent to the function while XXX_*STRING will not allocate or copy
4989 the data into the buffer. Instead it sets the pointer from the
4990 buffer into the pointer sent as argument (XXX_*STRING used to
4991 require that the pointer must be allocated already). This change
4992 makes this whole thing a bit more consistent and more optimized
4993 (note that the data returned in the unformatting with XXX_*STRING
4994 must not be freed now). The routines return now -1 on error.
4996 o Tried to find all code that use buffer_format and buffer_unformat
4997 and added return value checking to prevent formatting and
4998 especially unformatting errors and possible subsequent fatal
5001 o Changed ske->x and ske->KEY to mallocated pointers in
5002 lib/silcske/silcske.h. Fixed possible data and memory leak.
5004 o Added return value checking to all *_parse* functions. Fixed
5005 many memory leaks as well.
5007 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5008 so that buffer overflows would not happen. All code now also
5009 checks the return value as it can fail.
5011 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Added reconnection support to server if the normal server looses
5014 its connection to the router (for example if router is rebooted).
5015 The server performs normal reconnection strategy implemented
5016 to the server. Affected file silcd/server.c.
5018 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Added new packet type SILC_PACKET_SET_MODE that is used to
5021 distribute the information about changed modes (for clients,
5022 channels and clients channel modes) to all routers in the
5023 network. Updated the protocol specification accordingly.
5025 Added functions into silcd/packet_send.c and
5026 silcd/packet_receive.c: silc_server_send_set_mode,
5027 silc_server_set_mode.
5029 Added new files silcmode.[ch] into lib/silccore that implements
5030 the encoding and decoding of Set Mode Payload. Added new type
5031 SilcSetModePayload. Moved the definitions of different modes
5032 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5034 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Oops, a little mistake in server's connection authentication
5037 protocol. The protocol is not ended with FAILURE but with
5038 SUCCESS if the authentication is Ok. :) Affected file is
5041 * Implemented NICK_CHANGE notify handling in server in the file
5042 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5043 the local clients on the channel. After the changing nickname
5044 in router environment snhould work and the [<unknown>] nickname
5045 should appear no more.
5047 The silc_server_replace_id function that receives the Replace ID
5048 payload now sends the NICK_CHANGE notify type also in the file
5049 silcd/packet_receive.c
5051 * Changed WHOIS and IDENTIFY command to support the maximum amount
5052 of arguments defined in protocol specs (3328 arguments). This
5053 fixed a bug that caused problems when there were more than three
5056 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added extra parameter, command identifier, to the
5059 silc_client_send_command so that explicit command identifier
5062 Changed that ID list routines uses specific command identifier
5063 when sending WHOIS/IDENTIFY requests to the server so that they
5064 can be identified when the reply comes back.
5066 Affected files lib/silcclient/command.[ch],
5067 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5069 * Added `sender' argument to silc_server_packet_send_to_channel
5070 to indicaet the sender who originally sent the packet to us
5071 that we are now re-sending. Ignored if NULL. Affected file
5072 silcd/packet_send.[ch].
5074 * Added some server statistics support in silcd/server_internal.h
5075 SilcServerStatistics structure and around the server code. Also
5076 send some nice statistics information when client is connecting
5079 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Fixed channel ID decoding in server's JOIN command reply in
5082 silcd/command_reply.c
5084 * Fixed braodcasting of replace ID payload to not to send it if
5085 we are standalone server in silcd/packet_receive.c.
5087 * Fixed all channel message sending routines to not to send
5088 packets to clients that has router set, since they are routed
5089 separately in the same function earlier. Affects file
5090 silcd/packet_send.c and all channel packet sending functions.
5092 * In USERS reply, res_argv[i] are not allocated, the table
5093 is allocated. Thus changed that free the table, not its
5096 * In server's whois_check and identify_check if the client is
5097 locally connected do not send any WHOIS commands - they are not
5100 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Fixed some minor bugs in client when sending WHOIS command. The
5103 arguments was in wrong order.
5105 * Removed statis function add_to_channel from server in
5106 silcd/command.c that was previously used with the joining but
5109 * Tested USERS command in router environment successfully with two
5110 routers, two servers and two clients.
5112 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Reorganized the USERS command and command reply in client library
5115 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5116 When the command is given by user we register a pending command
5117 callback that will reprocess the command after the reply has been
5118 received from the server. When reprocessing the packet we then
5119 display the information. Thus, the USERS information is displayed
5120 now in the command callback instead of in the command reply
5121 callback. The processing of the command is same as previously
5122 when server has sent the command reply in the JOINing process.
5124 * Added to USERS command in silcd/command_reply.c to join the client,
5125 we didn't use to know about, to the channel after we've created
5126 a client entry for it. Also, for clienet we did know already still
5127 check whether it is on the channel or not and add it if not.
5129 * Removed silc_server_command_join_notify as the function and its
5132 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Changed the client's pending command handling to the same as the
5135 server's pending command handling. It is also now possible to
5136 execute command reply functions from other command reply
5137 function as the function callbacks for commands and command
5138 replies are one and same. The pending commands are not static
5139 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5140 in client connection context. Thus, pending commands are server
5141 connection specific as it is convenient.
5143 Changed the function silc_client_command_pending and
5144 silc_client_command_pending_del and added new function
5145 silc_client_command_pending_check. Removed the
5146 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5149 * Added cmd_ident, current command identifier, to the client
5150 connection context in lib/silcclient/client.h to keep track on
5151 command identifiers used in command sending. Client's command reply
5152 function handling now supports the mandatory command identifiers.
5154 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5155 funtions in client to fully support pending command callbacks.
5157 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5158 as one of the arguments to the application in the command reply
5161 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5162 before first releasing SILC but came back. Now it is removed again
5163 and should come back nomore. The FORWARDED flag was used only
5164 by the JOINing procedure by forwarding the command packet to router.
5165 Now, the JOINing procedure has been changed to more generic (due
5166 to various router environment issues) and FORWARDED is not needed
5167 anymore for anything. The protocol specification is yet to be
5170 Now, removed silc_server_packet_forward from server and the flag
5171 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5173 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Renamed NAMES command to USERS command. The NAMES was named that
5176 due to historical reasons. Now it is renamed. Also, rewrote
5177 parts of the USERS command. The nickname list is not sent anymore
5178 by the server. Only Client ID and mode lists are sent in the USERS
5179 command. Changed this also to the protocol specification.
5181 The client now resolves the names and stuff after it receives
5182 the USERS list from the server when joining to the channel.
5184 * WHOIS and IDENTIFY commands has been changed to support multiple
5185 Client ID's per command. One can now search for multiple users
5186 in the network by sending only one WHOIS or IDENTIFY command.
5187 Changed the code and the protocol specifications.
5189 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5190 uses silc_server_command_whois_parse to parse the request. */
5192 * If normal server, do not parse the WHOIS and IDENTIFY requests
5193 before sending it to the router. Saves some time.
5195 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Fixed JOIN command on client library. Wrong number of arguments
5198 used to crash the client.
5200 * Added silc_server_channel_has_global function to check whether
5201 channel has global users or not.
5203 * Added silc_server_channel_has_local function to check whether channel
5204 has locally connected clients on the channel.
5206 * The silc_server_remove_from_one_channel now checks whether the
5207 channel has global users or not after given client was removed from
5208 the channel. It also checks whether the channel has local clients
5209 on the channel anymore. If it does not have then the channel entry
5210 is removed as it is not needed anymore.
5212 * The silc_server_notify now checks on JOIN notify whether the joining
5213 client is one of locally connected or global. If it is global then
5214 the channel has now global users on the channel and that is marked
5215 to the channel entry. Also, it now saves the global client to
5216 global list who is joining and JOINs it to the channel. This is
5217 for normal server, that is.
5219 Changed silc_server_send_notify_on_channel,
5220 silc_server_packet_relay_to_channel and
5221 silc_server_packet_send_to_channel check if we are normal server
5222 and client has router set (ie. global client) do not send the
5223 message to that client, as it is already routed to our router.
5225 * Implemented LEAVE notify type handling in silc_server_notify
5228 * Tested LEAVE command in router environment successfully. Tested
5229 with two routers, two servers and two clients.
5233 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5235 * Implemented SIGNOFF notify type handling in silc_server_notify
5238 * silc_server_remove_id now removes the client entry from all channels
5239 it has joined and thusly sends SIGNOFF notify type.
5241 * Rewrote the NAMES list generation in server by removing two excess
5242 loops. The lists are created now inside one loop.
5244 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * silc_server_remove_channel_user checks now also global list
5247 for channel and client.
5249 * silc_server_new_channel_user checks now both local and global
5250 list for channel and client. Fixed a bug in client id decoding.
5251 Used to decode wrong buffer.
5253 * silc_server_channel_message checks now both local and global
5254 list for channel entry.
5256 * Tested channel joining (hence JOIN) in router environment
5257 successfully. Tested with two routers, two servers and two
5260 * Tested channel message sending in router environment successfully.
5262 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added silc_server_save_channel_key into server.[ch] to save the
5265 received channel key in Channel Key payload processing. It is
5266 also used in JOIN command reply handling.
5268 Equivalent function silc_client_save_channel_key added into
5269 client.[ch] into client library.
5271 * Changed JOIN command reply to send information whether the channel
5272 was created or not (is existing already) and the channel key
5273 payload. Changed protocol specs accordingly.
5275 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5276 the request was sent by ID and not by nickname. Crashed on
5279 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5282 now correctly save the received data.
5284 * silc_server_free_sock_user_data now notifies routers in the
5285 network about entities leaving the network.
5287 At the same time implemented functions silc_server_remove_id
5288 and silc_server_send_remove_id to receive and send REMOVE_ID
5289 packets. The packet is used to notify routers in the network
5290 about leaving entities. The ID removed will become invalid in
5293 * Added function silc_idlist_del_server into server. Removes and
5294 free's server entry from ID list.
5296 * silc_server_private_message function now checks, if we are router,
5297 that the destination ID really is valid ID, naturally.
5299 * In router when NEW_ID packet is received (for new client) the
5300 hash of the Client ID is saved in the ID Cache but the
5301 client->nickname is set to NULL, instead of putting the hash
5304 IDENTIFY command now also checks that client->nickname must be
5305 valid. If it is not if will request the data from the server who
5306 owns the client. Added new function
5307 silc_server_command_identify_check.
5309 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5310 to set the command to already allocated Command Payload.
5312 * Tested private message sending in router environment with two
5313 routers, two servers and two clients. Fixed minor bugs and now
5316 * Fixed segfault from client's NAMES command. Used to crash if
5319 * Forwarded packets must not be routed even if it is not destined
5320 to the receiver. Changed server code comply with this.
5322 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Added `require_reverse_mapping' boolean value to ServerParams
5325 structure. If TRUE (not default) the server will require that
5326 the connecting host has fully qualified domain name.
5328 If the reverse mapping is not required and hostname could not be
5329 found the IP address is used as hostname.
5331 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Implemented version string checking to both client and server.
5334 The check is incomplete currently due to the abnormal version
5335 strings used in development version of SILC.
5337 * Changed all command functions in server to use the new
5340 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Changed char *data to unsigned char *data in ID Cache system to
5343 support binary data as ID Cache data. Changed code to support
5344 binary data in lib/silccore/idcache.c.
5346 * Renamed silc_server_packet_relay_command_reply to
5347 silc_server_command_reply as it is normal packet receiving
5348 function. Rewrote the function to accept command replys for
5349 servers and not only for clients.
5351 * Mark remote router always as registered server if we are connecting
5352 to it. Otherwise, commands sent by the router to us are ignored.
5354 * All ID List find routines now returns the ID Cache Entry pointer
5355 as well if requested.
5357 * WHOIS command works now in router environment, tested with two
5358 routers, two servers and two clients.
5360 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5361 in router environment (as it is almost equivalent to WHOIS) but
5362 hasn't been tested thoroughly. Added new functions:
5364 silc_server_command_identify_parse
5365 silc_server_command_identify_send_reply
5366 silc_server_command_identify_from_client
5367 silc_server_command_identify_from_server
5369 * Disabled route cache adding because adding two different ID's with
5370 same IP replaces the old cache entry thus giving wrong route.
5371 The entry->router->connection is always the fastest route anyway
5372 so route cache may not be needed. Of course, new routes maybe
5373 established after receiving the ID when the entry->router->connection
5374 might not be anymore the most optimal.
5376 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Add route cache for received ID for fast routing.
5380 * Added silc_server_packet_route to route received packet on router
5381 that is not destined to us.
5383 * Renamed silc_server_get_route to silc_server_route_get.
5385 * Added id_string and id_string_len fields into SilcServer to
5386 include encoded ServerID for fast comparing without excess
5387 encoding of the ID's.
5389 * Cleaned up WHOIS command on server side. Added following static
5392 silc_server_command_whois_parse
5393 silc_server_command_whois_check
5394 silc_server_command_whois_send_reply
5395 silc_server_command_whois_from_client
5396 silc_server_command_whois_from_server
5398 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5399 arguments in command replies. All command functions should be
5400 updated to use this macro.
5402 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Minor typo fixes on command reply handling on server.
5406 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Added silc_server_command_add_to_channel internal routine to add
5409 the client to the channel after router has created the channel and
5410 sent command reply to the server.
5412 * Added generic silc_server_send_command to send any command from
5415 * Use static buffer with ID rendering instead of duplicating data.
5417 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Fixed a channel user mode bug when joining to a channel server gave
5420 everybody channel founder rights, oops.
5422 * We mark ourselves as the router of the incoming server connection
5423 if we are router ourselves. This way we can check in some packet
5424 sending functions whether it is locally connected server. For
5425 incoming router connections we put NULL.
5427 * For router sending packets locally means now always sending the
5428 packet cell wide; to local clients and local servers. For normal
5429 server sending packet locally means sending it to only local
5432 * Fixed the JOIN command to really work in router environment. If the
5433 channel is created it is always created by the router. Router is
5434 also responsible of making the initial joining to the channel,
5435 sending JOIN notify to the sending server and distributing
5436 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5437 does not exist server doesn't do anything else but forward the
5438 command to the router which performs everything.
5440 * Added silc_server_send_channel_key function to send the Channel Key
5443 * Added silc_server_create_channel_key to create new channel key. The
5444 channel key is now re-generated everytime someone joins or leaves
5445 a channel, as protocol dictates. Note: channel->key_len is the
5448 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5451 packet_receive.[ch] to separate packet sending and receiving
5452 routines. The server.[ch] now includes everything else including
5453 actual packet processing (writing and reading data) and other
5456 Renamed silc_server_private_message_send_internal to
5457 silc_server_send_private_message. The routine is still though
5458 used only to relay private messages as server does not send
5459 private messages itself.
5461 Renamed silc_server_new_channel to silc_server_create_new_channel
5462 and added new function sicl_server_new_channel that handles the
5463 incoming New Channel packet. Added also new sending function
5464 silc_server_send_new_channel to send New Channel Payload.
5466 * Added new function silc_server_notify to process incoming notify
5467 packet to the server/router. Server may then relay the notify
5468 to clients if needed.
5470 * Added new function silc_server_new_channel_user to process incoming
5471 New Channel User packet. Router will redistribute the packet and
5472 send JOIN notify to its local clients and locally connected servers
5473 if needed. Normal server will send JOIN notify to its local client
5474 on same channel when received this packet. Added also corresponding
5475 sending function silc_server_send_new_channel_user to sent the
5478 * Added boolean route argument to send_notif_to_channel and
5479 packet_send_to_channel functions to attempt to route the packet
5480 if it is TRUE and send only locally if it is FALSE.
5482 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * silc_server_replace_id now broadcasts the received replace ID
5485 packet if it is not broadcast packet already. The router must
5486 broadcast to inform other routers about changed ID.
5488 * Added backpointer to server's router into SilcServer context in
5489 silcd/server_internal.h.
5491 * Fixed silc_server_packet_broadcast to send correct broadcast
5494 * The channel key is now distributed to the local client as soon
5495 as it is received from the router (in router environment) so that
5496 no other packet may be sent for the channel until client has
5499 * silc_server_remove_channel_user now broadcasts the received
5500 Remove Channel User packet if it is not broadcast packet already.
5501 The router must broadcast to inform other routers about removed
5504 * Added users field into SilcPacketContext that is a reference count
5505 of the context. One can increase the reference count by calling
5506 silc_packet_context_dup which is now changed to just increase the
5507 reference count instead of duplicating the data. The reference
5508 count is decresed by calling silc_packet_context_free that will
5509 free the data after the reference count hits zero.
5511 For now on the packet context and everything allocated into it
5512 (including the raw packet from network) must be freed by calling
5513 the new silc_packet_context_free function. Added also new function
5514 silc_packet_context_alloc that must be used now to allocate the
5515 context. This also means that if a routine is asynchronous from
5516 silc_[client/server]_packet_parse_type the packet context must
5517 be duplicated by calling silc_packet_context_dup. Otherwise it
5518 gets free'd after silc_[client/server]_packet_parse_type returns.
5519 Also, one must remember that if packet is duplicated then its
5520 reference count must be decresed by calling the free function as
5521 many times as it was duplicated.
5523 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5524 from both client and server.
5526 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Made joining to a channel working in router environment.
5530 * Cleaned up JOIN command on server side and create function
5531 silc_server_command_join_channel internal routine to make the
5534 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Changed silc_command_pending list to SilcDList. Also, added
5537 `ident' field to SilcServerCommandPending structure to identify
5538 the reply and to call correct callback.
5540 Added silc_server_command_pending_check function to replace the
5541 corresnponding macro. The silc_command_pending list is not
5544 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5545 to set identifier to previously allocated Command Payload. It
5546 is used to set identifier for command when resending Command
5549 * Added silc_command_payload_encode_payload to encode Command
5550 Payload buffer from SilcCommandPayload structure.
5552 * Added silc_argument_payload_encode_payload to encode Argument
5553 payload buffer from SilcArgumentPayload structure.
5555 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Changed WHOIS command to support router connection on server side.
5558 The whois request is always sent to router unless the server is
5559 standalone server. After server has received the reply from the
5560 router will it send the reply to the client.
5562 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5563 broadcast received broadcast packet. The function is used only
5564 by router. The broadcast packet is always sent to the router's
5567 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5568 render given ID to printable string, for log files for example.
5570 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Made basic router to router connections working. At least they
5573 can now connect to each other but nothing really works the way
5574 they are supposed - yet.
5576 * Added new initiator token to RouterConnection configuration
5577 file in silcd/serverconfig.[ch]. It is used to tell whether we
5578 are the initiator to the remote router or whether we'll expect
5579 the other end to connect.
5581 * Moved registering of listener task to silc_server_init, hence
5582 the server starts listenning as soon as it is run, even if it
5583 does not have connections to other routers. Let's see how well
5586 * Changed default connection retry timeouts for more suitable in
5589 * Removed cipher and such arguments from silc_idlist_add_client
5590 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5591 Added new function silc_idlist_add_data to add the keys and stuff
5594 * Added SilcIDListData structure and added it to SilcClientEntry
5595 and SilcServerEntry as their first field in the structure. This
5596 way we can explicitly cast the ID entries to the SilcIDListData
5597 structure and get common data for the entries. In past, we had
5598 to first check what type of connection it is and then cast it to
5599 correct ID entry type. Now, we can directly cast the opaque
5600 pointer to the SilcIDListData (no matter what ID entry it actually
5601 is) and get the data needed.
5603 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5606 in some circumstances even if threre were timeout tasks, though not
5607 IO tasks, but tasks anyway. Now fixed.
5609 * Defined SilcServerConnection structure to hold connection specific
5610 stuff about directly connected servers and routers. The definition
5611 is currently in silcd/server_internal.h. I thought about having
5612 a bit more important role fro this struct but for now it is used
5613 only when connecting to other server (or router actually).
5615 * Added connecting retry support in server when connecting to
5616 router(s). The retry feature implement exponential backoff
5617 algorithm. Also, added SilcServerParams structure to hold default
5618 parameters for server. For now, it include these retry settings
5619 and are hard coded. After server is moded to be as Silc Server
5620 Library this structure will be more important.
5622 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Changed client librarys channel->clients table to SilcList and
5625 changed code accordingly.
5627 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Changed client's channel table to SilcList and changed code
5630 accordingly. Also changed SilcChannelClientEntry to include back-
5631 pointer to the channel so that client entry can use that structure
5632 as list as well and we have fast cross-reference to the channel.
5633 This change dramatically decreased the complexity of channel
5634 handling with client entry and vice versa (removed one extra
5635 loop when searching for channel entry from many functions).
5637 * Changed server->sim from table to SilcDList and changed code
5640 * NAMES command can now be used from user interface. It will show
5641 the user list on the channel, neatly.
5643 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5644 Code now saves realname of the user if it becomes available.
5646 * Renamed configure.in to configure.in.pre and made ./prepare
5647 script to automatically add correct version string to
5648 configure.in which it creates from configure.in.pre.
5650 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * NAMES command reply now shows users mode with the nickname when
5655 * Moved silc_client_ch[u]mode[_char] functions from
5656 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5657 place sucks, they are utility functions and should be in some
5660 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5662 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5665 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added TRQ (efficient deque and list library) into lib/trq. This is
5670 a very good list library that is currently used in the SILC. Defined
5671 SilcList API over the library because I didn't like the API very
5672 much. See lib/trq/silclist.h for the API and examples of how to
5673 use the API. Fixed various places in the code to use the new
5674 SilcList API. The SilcList is meant for lists that has a structure
5675 already defined as a list. It is not suitable to add just some
5676 context to the list (in TRQ, the context is the list actually).
5678 So, I defined SilcDList that can be used for the purpose where
5679 predefined list structure does not exit. This can be used as
5680 such list. Now some context just can be added to the SilcDList.
5681 Currently this list is not used in the SILC just yet, though there
5682 are a lot places where this can replace dynamically allocated
5683 tables and I will fix these places, later, to use SilcDList.
5684 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5685 and use TRQ internally).
5687 Also fixed some annoying warning messages that the original TRQ
5688 code generated. Also minor changes to TRQ's Makefile.in.
5690 * Added support for querying by Client ID to both WHOIS and
5691 IDENTIFY commands into server, as required by the protocol.
5693 * Removed method function pointers from SilcBuffer structure. They
5694 weren't used to anything and just increased the context size for
5695 no good reason. This change also made silc_buffer_alloc and
5696 silc_buffer_free functions inline functions.
5698 * Disabled command flooding detection support until it's fixed so
5699 that it accepts commands in but does not execute them more than once
5702 * Added silc_net_localhost(), to return local hostname, into
5703 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5704 that must be initialized before calling silc_client_init.
5706 * Added new function: silc_server_send_notify_on_channels to send
5707 notify messages to all channels client has joined. It is assured
5708 that the message is sent only once per client.
5710 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5711 lib/silcutil/silcutil.[ch] as silc_format function. The new
5712 function is generic and is used by server as well, not only by
5713 the logging routines.
5715 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5716 the provided version string was not acceptable. Added new function:
5717 silc_ske_check_version into lib/silcske/silcske.h. The function
5718 must be implemented by the application (client or server) and it
5719 does not reside in the SKE library. The function checks the version
5720 string remote end sent.
5722 * Added back pointers (to opaque context and to SilcSocketConnection)
5723 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5725 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5726 duplicate packet context structure.
5728 * Changed `notify' client operation to send same arguments as client
5729 receives from server except for ID's. ID's are mapped to correct
5730 ID entry and that is returned. Also, if channel entry is not sent
5731 by server but the notify is for channel the channel entry is sent
5732 to application (otherwise application doesn't know that it is for
5733 channel (library gets it from packet's Destination ID)).
5735 * Added silc_client_remove_from_channels into client library to
5736 remove a client from all channels it has joined to. Used when
5737 received SIGNOFF notify from server. Added also new function
5738 silc_client_replace_from_channels to replace old ID entry with
5739 new ID entry on all channels. Used when received NICK_CHANGE
5742 * Fixed ID Cache list handling in silc_idlist_get_client in
5743 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5744 to get (or query) client by ID.
5746 * Updated TODO list.
5748 * Added connection authentication status message defined by the
5749 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5750 support for these into the code in client and server side.
5752 * Added generic function silc_client_send_command to send any command
5753 with variable argument list. Application should use this function
5754 to send commands if the command functions provided by the library
5755 does not suite for the application's user interface needs.
5757 * Added new `failure' client operation. Application is notified about
5758 received failure packet if client is executing a protocol. In this
5759 case the protocol's execution has failed.
5761 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5762 is required by the protocol.
5764 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5765 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5768 * Added status flag to SilcSKE object to indicate realtime status
5769 of the SKE protocol.
5771 * Application receives now exactly same command reply arguments as
5772 the library receives from server. However, if ID is received the
5773 corresponding ID entry is returned to the application (eg. Client
5774 ID is mapped to correct SilcClientEntry entry and that is returned).
5775 Changed command_reply client operation due to this change.
5777 * Changed all ID's in commands and in command replys as ID Payloads.
5778 Change affected both client and server side codes.
5780 All ID's sent in SILC network (with execption of ID's in SILC
5781 Packet header) are sent in ID Payload to support variable length
5784 * Server now notifies nick changes and notifies all clients on
5785 the channels about the new nickname (about the new Client ID,
5788 * Implemented CMODE command to change channel modes. Supports all
5789 channel modes defined by the protocol specs except ban and invite
5790 lists. (Also, private channel key mode is supported but support for
5791 setting private channel key in client is missing, thus, this mode
5792 has no effect on client side (except that server requires that the
5793 client uses private channel key and normal channel traffic does not
5796 Also, invite mode works per se, but INVITE command does not work
5797 yet correctly, so you can set channel as invite only channel but
5798 inviting clients to the channel does not work (it is yet to be
5799 thought what's the best way to do it).
5801 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5802 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5803 Implemented CUMODE command to change user's mode on the channel.
5804 Supports all modes defined by the protocol specs.
5806 * Added NAMES command reply to return users modes on the channel.
5808 * Removed unnecessary and slow ciphers from lib/silccrypt.
5810 * Set SO_KEEPALIVE option to connection sockets by default.
5812 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5814 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5815 redefined the Notify Payload into protocol specs.
5817 * Added silc_id_payload_parse_id to get ID directly from raw
5820 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5823 accept searching by Client ID as well.
5825 * Added support for LEAVE and SIGNOFF notify types in client library.
5827 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5828 to parse ID Payload from raw data.
5830 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Added flags parameter into silc_ske_assemble_security_properties
5833 function in lib/silcske/silcske.[ch].
5835 * Changed notify client operation to fit better for notify messages
5836 sent by server. The notify payload received from server is now
5837 passed to the application (after parsing it to SilcNotifyPayload).
5838 It is application's responsibility to retrieve the arguments
5839 from the payload and show the message the way it wants. The message
5840 sent by server is implementation specific.
5842 * Changed public keys to comply with the protocol specification.
5843 Old public keys are not supported anymore and are not compatible.
5845 * Removed nickname from Channel Payload as the latest draft removed
5846 it. The client must resolve the nickname from the NAMES command
5847 reply received when it joined the channel.
5849 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5851 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Fixed some errors in protocol specification drafts.
5855 * Created lib/silccore/silcnotify.c to implement Notify Payload
5856 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5857 generic payloads described by protocol specifications. The file
5858 includes implementations for ID Payload and Argument Payload.
5860 * Changed Command Payload implementation to use the new Argument
5861 Payload. Changed command_xxxx_payload to command_payload_xxxx
5862 to comply with SILC coding conventions.
5864 * Added suppport for Argument Payload handling in Notify Payload
5865 implementation as protocol requires it. Added the new support
5866 into server and client lib as well.
5868 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added support for multiple nicknames on same channel. [n] is
5871 added locally to the nickname if there are more than one same
5872 nicknames on the channel.
5874 * Server now sends all nicknames that matched WHOIS request.
5875 Client also shows the list received from server.
5877 * Added TOPIC command to client side. User can now set and show
5878 current topic on channel.
5880 * Added MOTD command to client and server. Also, server sends the
5881 motd when client connects to the server.
5883 * Changed version strings to comply ISO 8601.
5885 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Fixed protocol error handling in client library. It should now
5888 cope even if the SKE fails for some reason.
5890 * Made new protocol specification drafts for submitting to IETF.
5892 * Implemented TOPIC command to server in silcd/command.c.
5894 * Added two new notify types into lib/silccore/silcnotify.h:
5895 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5896 notify nickname change and topic setting/change on a channel.
5898 * API change of command_reply operation in client library. The
5899 application gets now the status type received from server as well.
5901 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5905 * Cras fixed and optimized the packet handling even further and
5906 it should work now. Minor change to the prototype of function
5907 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5909 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Added new function into lib/silcutil/silcschedule.[ch]:
5912 silc_schedule_with_fd to select() a specified fd. The function
5913 returns after timeout expires or data arrives or goes. The
5914 function is used by packet routines to wait that all data is
5915 received from network.
5917 * Fixed data reading from network in lib/silccore/silcpacket.c.
5918 The code now assures that all data is read from the fd and then
5919 continues packet processing. This was a bug fix since the code
5920 used to drop some data in some circumstances.
5922 * Added new function into lib/silcclient/client.[ch]:
5923 silc_client_start_key_exchange to start key exchange after
5924 connection has been established to server. The code internally
5925 now uses this funtion but its main purpose was to provide it
5926 for applications that perform their own connecting. After
5927 application has created a connection it merely calls this
5928 function to start the key exchange between client and server.
5929 The library takes care of everything else after that.
5931 Updated also lib/silcclient/README to explain the usage of
5934 * Do not send to application information that connection has
5935 been established. Application gets notified it by connect
5938 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Applied cras's patch to add silc_schedule_one function. The
5941 function runs scheduler once and returns.
5943 * Fixed the scheduler after cras messed it up. The timeout
5944 handling works now as it's supposed to work.
5946 * Added into lib/silccore/ silcnotify.h to include notify
5947 message types support. Changed silc_server_send_notify*
5948 functions, in server.[ch], to support those new notify types.
5949 Added the support for the notify types into client library,
5950 as well. Added new notify client operation into ops.h in
5953 * Changed silc_server_packet_send_to_channel to send normal
5954 packets instead of just channel message packets. The function
5955 is now used to send the notify packets to channels. It is not
5956 used to send channel message packets anymore, as server never
5959 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5960 va_arg()s as it seems to require it nowadays. I guess, if SILC
5961 is compiled with older va_arg() the new code should work anyway.
5963 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Splitted core library. Core library (lib/silccore) includes
5966 now only SILC protocol specific core (and common) components.
5967 Created new utility library (lib/silcutil) that includes more
5968 generic purpose stuff. The stuff for util library was taken
5969 from the old core library. This was minor and easy split.
5971 * Created SILC Client Library (lib/silcclient) that includes
5972 implementation of the SILC client without user interface. This
5973 was major move from silc/ directory. The code has been changed
5974 so that it is transparent towards the user interface. The
5975 silc/ directory includes now the same user interface as before
5976 and it uses the new client library. Read lib/silcclient/README.
5977 Basicly, the client library performs everything else related
5978 to SILC except user interface handling. Also, configuration
5979 files are considered to be part of user interface and library
5980 does not handle them.
5982 This change also changed a lot of structures, function naming etc.
5983 Most important change was that SilcClientWindow object was
5984 renamed to SilcClientConnection in the client library. Created
5985 also new file lib/silcclient/ops.h. Also added new files
5986 silc/local_command.[ch] and silc/client_ops.[ch].
5988 All these changes were made to make it easier for user interface
5989 designers to create what ever user interface for the SILC client
5992 It is also expected that the server will be moved to lib
5993 directory as well and SILC Server Library will be created;
5994 sometimes in the future.
5996 * Removed Local commands from lib/silccore/silccommand.h as
5997 they are application specific and new client library does not
5998 handle any of those anymore.
6000 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6001 old client implementation in silc/.
6003 * Added support for callback functions in SILC_LOG_* macros.
6004 Application can now set its own callbacks that will be called
6005 instead of using the default functions that will always print
6006 the debug messages to stderr (or stdout). Also, debugging can
6007 now be disabled by setting silc_debug to FALSE and re-enabled by
6008 setting it to TRUE. Note, that logging will still work even
6009 if debugging is disabled.
6011 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6012 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6013 silc_log_reset_debug_callbacks.
6015 * To enable debugging in silc client one must give now -d
6016 option on command line.
6018 * Changed silc_schedule_init to automatically allocate task queues
6019 if they are not allocated before calling it.
6021 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Added GMP 3.1 into math library.
6025 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6028 a channel in SILC network. The packet is used by servers and
6029 routers to notify other routers that user has left a channel.
6030 This little feature was missing until now. Added the feature
6031 to protocol specification as well.
6033 Added functions: silc_server_send_remove_channel_user and
6034 silc_server_remove_channel_user into server.[ch].
6036 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6037 lib/silccore/silcpacket.h. However, they are not implemented
6040 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Fixed joining to a channel and sending channel messages
6043 between server and router. The channel message sending should
6044 now work inside a cell.
6046 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Fixed the private message sending between server and router.
6049 The private message sending should now work inside a cell.
6051 * Added silc_server_replace_id into server.[ch] to replace
6052 existing ID in the SILC network.
6054 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6055 and silc_idlist_replace_server_id into idlist.[ch] in server.
6057 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Fixed the server to server connections. Server can again now
6060 connect to router. Router to router connections probably does
6063 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Added dynamic protocol registering support. Now protocols can
6066 registered and unregistered on the fly. Patch by cras.
6068 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Added lib/contrib directory to hold routines that some platforms
6071 don't have but are needed by SILC.
6073 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6074 into lin/contrib to provide getopt() and getopt_long() for
6075 those who don't have it.
6077 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Added AWAY command to client. When away message is set and
6080 client receives a private message packet the client automatically
6081 replies to the sender with the away message.
6083 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6084 bug seemed to be the cause of recent problems when compiling
6087 * Added version detection support to SKE protocol specification
6088 and added the new changes to the SKE implementation as well.
6089 There were other minor changes in the SKE protocol as well.
6091 Many changes in lib/silcske/silcske.[ch] and in
6092 lib/silcske/payload.[ch].
6094 * Added ^U functionality, clear input line. Patch from cras.
6096 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Mainly small bugfixes on core library. Fixed some debugging
6099 logging and buffer overflow in silclog.c.
6101 * Updated config.sub and config.guess on the distribution tree.
6103 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Added command lagging support in server. Client may execute
6106 commands now only once in two seconds.
6108 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Optimized packet reception. MAC computation and checking is now
6111 also more optimized. A lot previously duplicated code is now
6112 used as generic by both client and server.
6114 * Fixed key pair generation in clientutil.c
6116 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Added into lib/silccore/silcbufutil.[ch] new function;
6119 silc_buffer_realloc.
6121 * Moved generic packet sending/encryption functions to
6122 lib/silccore/silcpacket.[ch] from client and server. Some
6123 rewriting of the functions.
6125 * Moved all generic packet reception/decryption functions to
6126 lib/silccore/silcpacket.[ch] from client and server. The
6127 packet processing is now much cleaner in both client and server.
6128 These were major changes in both client and server.
6130 * Created many common functions in server to do packet sending.
6131 Previously code were duplicated a lot, this has been removed
6134 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Rewrote major parts of the ID cache system. Don't know
6137 whether it is better now or not but at least the API is more
6140 * Major rewrite on ID cache stuff on client because of the ID
6141 cache API changes. Added idlist.c to client.
6143 * Also major rewrite on ID cache stuff on server as well.
6144 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6145 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6146 in hand, instead they are all put into the ID cache system now.
6147 All server_idlist_* routines uses ID cache now instead of
6148 traversing its own lists (those lists does not exist anymore).
6149 SilcIDList though still exists. Also, SilcXXXEntry's are
6152 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * Finally made the SKE implementation compliant to the protocol
6155 specification. All mp integers are now binary encoded as
6156 opposed being HEX encoded.
6158 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6161 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6162 functions: silc_[encode/decode]_pem. Also added function
6163 silc_encode_pem_file to PEM encode with newlines ('\n') for
6166 * SILC public keys are now encoded either PEM or binary. Same
6167 option is for private keys as well. By default private keys
6168 are binary encoded and public keys PEM encoded. Silly HEX
6169 encoding were removed.
6171 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6172 function to create fingerprints.
6174 * Fixed a bug in SHA1; does not change the original data anymore.
6176 * Partly implemented INFO command on client and server side.
6177 Fixed CLEAR command. Changes to SERVER command; show current
6178 server(s) when giving command without arguments. Added
6179 VERSION command to client.
6181 * Added check to server that unregistered connections cannot
6182 execute commands (unless it is specificly allowed).
6184 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Fixed screen refresh.
6188 * Fixed channel joining bug from client. On some circumstances
6189 client tried to join to a channel it had already joined.
6191 * Added public key verification process into client's protocol.c.
6192 The client now verifies the public key from user and saves
6193 it into ~./silc/serverkeys/ directory.
6195 Added into: clientutil.[ch]: silc_client_verify_server_key.
6197 * Changed SKE protocol's silc_ske_initiator_finish function
6198 to accept callback function that verifies the received public
6199 key. Removed old silc_ske_verify_public_key function.
6201 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6204 silc_pkcs_private_key[_data]_set.
6206 * Made the password and public authentication more cleaner in
6207 server's protocol.c.
6209 * Removed historic and obsolete protocol `channel_auth' from
6210 both client and server.
6212 * Removed wrong way of sending command status messages from
6213 server to client in server's command.c. The old way violated
6214 protocol specification.
6216 Changes to silccore/silccommand.[ch]: removed
6217 silc_command_encode_status_payload -> not needed anymore,
6218 changed silc_command_encode_payload_va to accept extra
6219 argument on variable argument list. The argument type must
6220 now be provided to the function. Also, added new function:
6221 silc_command_encode_reply_payload_va which is same as
6222 normal command_encode_payload_va except command status type
6223 is provided as extra argument.
6225 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added ~./silc directory handling. The directory includes the
6228 public and private keys for the client.
6230 Added silc_client_check_silc_dir, silc_client_create_identifier
6231 and silc_client_load_keys.
6233 * Implemented SILC protocol compliant public key. Added public
6234 and private key saving to and loading from files.
6236 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6237 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6238 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6239 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6240 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6242 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6243 silc_pkcs_load_[public/private]_key.
6245 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Added silc_server_get_route (route.[ch]) to get connection
6248 data for the fastest route for given ID.
6250 * Implemented INVITE command on client and server. The command
6251 were re-defined in the SILC Protocol Specification and the
6252 implementation now complies with the specification.
6254 * Implemented PING command on client and server.
6256 * Implemented NAMES command on client and server. The server side
6257 supports currently only normal server not router server yet.
6258 Some changes to NAMES definition in SILC protocol specification.
6260 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Implemented LEAVE command on client and server.
6264 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6265 again. This change was made to the protocol as well. Server
6266 should not violate the protocol specification anymore.
6268 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6271 was tested. SOCKS4 was not but should work anyway.
