1 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed silc_client_channel_message to not try to decrypt
4 the message twice if it resolved the destination client
5 information. This could cause of dropping one channel
6 message. Affected file lib/silcclient/client_channel.c.
8 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Added silc_client_run_one into lib/silcclient/silcapi.h and
11 lib/silcclient/client.c. This function is used when the SILC
12 Client is run under some other scheduler, or event loop or
13 main loop. On GUI applications, for example this may be
14 desired to used to run the client under the GUI application's
15 main loop. Typically the GUI application would register an
16 idle task that calls this function multiple times in a second
17 to quickly process the SILC specific data.
19 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
21 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
24 * Write PID file after dropping privileges. Added -F option
25 to run server on foreground. A patch by debolaz.
26 Affected files silcd/server.c, silcd/silcd.c.
28 * Fixed MOTD to return the MOTD file server name. Affected
31 * Added INFO command reply handling to the Irssi SILC Client.
32 Affected file irssi/src/silc/core/client_ops.c.
34 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
36 * Fixed the silc_idcache_list_* routines to really support
37 the dynamic list. Fixes a crash. Affected file is
38 lib/silccore/silcidcache.c.
40 * Fixed the LIST command reply to really call LIST command's
41 pending callbacks. Affected file silcd/command_reply.c.
43 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
45 * Update conn->local_entry->nickname after giving NICK
46 command. Affected file lib/silcclient/command.c.
48 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
50 * Added the [pid] option to the silcd configuration file
52 Affected files: serverconfig.[ch] and silcd.c
54 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Save fingerprint in WHOIS command reply in server.
57 Affected file silcd/command_reply.c.
59 * Fixed NICK commands pending callback registration.
60 Affected file lib/silcclient/command.c.
62 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
64 * Use ++server->cmd_ident when sending commands in server,
65 instead of random number. Affected file silcd/command.c.
67 * Fixed GETKEY command reply to call actually GETKEY pending
68 command callbacks. Affected file silcd/command_reply.c.
70 * A bit stricter check for nicknames. Check for same nickname
71 in NICK command also. Affected file silcd/command.c.
73 * Do not call INFO command everytime client ID changes, only
74 during first connecting. Affected file lib/silcclient/client.c.
76 * Set the new nickname only after successful command reply for
77 NICK command is returned by server. Affected file
78 lib/silcclient/command.c.
80 * Remove nicknames from nicklist during server_signoff notify.
81 Should fix /NAMES bit more. The affected file is
82 irssi/src/silc/core/silc-channels.c.
84 * Added `fingerprint' field to the SilcIDListData in the
85 silcd/idlist.h to hold the fingerprint of the client's
88 Send the fingerprint of the client's public key in WHOIS
91 Affected files silcd/command.c, and silcd/idlist.[ch].
93 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
94 create fingerprint from given data.
96 * Show the fingerprint of the client's public key in WHOIS.
97 Affected files irssi/src/module-formats.[ch] and
98 irssi/src/silc/core/client_ops.c.
100 * Format the multiple same nicknames also during JOIN and
101 NICK_CHANGE notifys. Affected file is
102 lib/silcclient/client_notify.c.
104 * Do not print error on screen for invalid private message
105 payload since it can come if someone is sending private
106 messages with wrong key. Affected file
107 lib/silccore/silcprivate.c.
109 * Fixed multiple concurrent /PING crash. Affected file
110 lib/silcclient/command.c.
112 * Changed the wrong ID encoding. All IP addresses must be
113 in MSB first order in encoded format. They were encoded
114 wrong and was in LSB format. Affected files are
115 silcd/serverid.c, lib/silcutil/silcutil.c.
117 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
119 * Call the `connect' client operation through the scheduler
120 in case of error. Affected file lib/silcclient/client.c.
122 * Call the `failure' client operation even if the error
123 occurred locally during a protocol. Affected file is
124 lib/silcclient/protocol.c.
126 * Added support of sending LIST command to router from normal
127 server. This way normal server can get list of all channels
128 in the network too. Fixed the channel list sending in the
129 server too. Affected files are silcd/command.c, and
130 silcd/command_reply.[ch].
132 * Added silc_server_update_channels_by_server and
133 silc_server_remove_channels_by_server. They are used during
134 disconnection of primary router and in backup router protocol.
135 Affected file silcd/server_util.[ch], silcd/server.c and
136 silcd/server_backup.c.
138 * Fixed channel adding to global list in IDENTIFY command
139 reply in server. Affected file silcd/command_reply.c.
141 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
143 * If the incoming packet type is REKEY or REKEY_DONE process
144 that packet always synchronously. Fixes yet another MAC
145 failed error on slow (dialup) connections. Affected file
146 lib/silcclient/client.c and silcd/server.c.
148 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
150 * Call check_version SKE callback for initiator too. Affected
151 file lib/silcske/silcske.c.
153 * Implemented fix for security hole found in the SKE that was
154 fixed in the specification few days back; the initiator's
155 public key is now added to the HASH value computation.
156 Added backwards support for the old way of doing it too, for
157 old clients and old servers. Affected file is
158 lib/silcske/silcske.c.
160 * Enabled mutual authentication by default in SKE. If initiator
161 is not providing mutual authentication the responder will
162 force it. This will provide the proof of posession of the
163 private key for responder. The affected files are
164 lib/silcclient/protocol.c and silcd/protocol.c.
166 * Do not cache anymore the server's public key during SKE.
167 We do mutual authentication so the proof of posession of
168 private key is done, and if the server is authenticated in
169 conn auth protocol with public key we must have the public
170 key already. Affected file silcd/protocol.c.
172 * Added new global debug variable: silc_debug_hexdump. If
173 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
174 file lib/silcutil/silclog.[ch].
176 * Fixed compilation warning due to char * -> const char *.
177 Affected files lib/silcutil/silcnet.h, and
178 lib/silccore/silcauth.[ch].
180 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
182 * Fixed CMODE command when new channel key was created. If
183 the creation failed the old key was removed. Next time giving
184 same command would crash the server since the old key was
185 freed already. Affected file silcd/command.c.
187 * Fixed the silc_server_announce_get_channels to not crash
188 on reconnect. Affected file silcd/server.c.
190 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
192 * Added silc_log_set_debug_string function to set a regex
193 string to match for debug output. Only the function names,
194 or filenames matching the given debug string is actually
195 printed. This way it is possible to filter out those debug
196 strings that user is not interested in.
198 Fixed a bug in silc_string_regexify.
200 Affected files lib/silcutil/silclog.[ch], and
201 lib/silcutil/unix/silcunixutil.c.
203 * Changed the -d options in both server and Irssi SILC client
204 to take the debug string as argument. Affected files
205 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
207 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
209 * Added silc_hash_babbleprint to create a Bubble Babble
210 Encoded fingerprint. The encoding is developed by Antti
211 Huima (draft-huima-babble-01.txt), and it creates human
212 readable strings out of binary data. Affected file
213 lib/silccrypt/silchash.[ch].
215 * Print the babble print now in addition of fingerprint as well
216 in Irssi SILC client. Affected files are
217 irssi/src/fe-common/silc/module-formats.[ch],
218 irssi/src/fe-common/silc/core/client_ops.c.
220 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
222 * Fixed a security problem found in SKE. The initiator's
223 public key too is now added to the HASH hash value creation
224 which is signed by the responder to create the SIGN value.
225 This will prevent anyone in the middle to lie to the responder
226 about the initiator's public key. If this is done now, the
227 man in the middle will get caught. Updated the protocol
230 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
232 * Better installation directory handling. Configure module
233 paths and other paths automatically to example_silc* files
234 in doc/. A patch by toma.
236 * Fixed compiler warning from MPI library, and from SILC RNG.
239 * Added SILC_SERVER_PID_FILE to define the pid file for server.
240 It can be configured with ./configure. A patch by toma.
242 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
244 * Find correct make to use in prepare-clean. A patch by
245 toma. Affected file prepare-clean.
247 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
249 * Added irssi variables use_auto_addr, auto_bind_ip,
250 auto_bind_port and auto_public_ip.
252 * Changed the interface for silc_client_send_key_agreement
253 in lib/silcclient/silcapi.h
257 irssi/src/silc/core/silc-core.c
259 lib/silcclient/silcapi.h
260 irssi/src/silc/core/silc-channels.c
261 lib/silcclient/client_keyagr.c
264 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
266 * Added silc_pkcs_public_key_compare to compare two
267 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
269 * Check that the client who set the founder mode on the
270 channel is the same client that is giving the founder
271 mode to itself. It is done by comparing the saved public
272 key (it is saved even in the authentication is passphrase).
273 Affected file silcd/command.c.
275 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
277 * Do not process packet for disconnected socket connection.
278 Affected file lib/silccore/silcpacket.c.
280 * Process the DISCONNECT packet through scheduler in the
281 client library. Affected file lib/silcclient/client.c.
283 * Fixed the silc_client_packet_parse to not to increase
284 the packet sequence number if the conn->sock and the
285 current socket connection is not same. This can happen
286 for example during key agreement when the conn includes
287 multiple socket connections (listeners). Affected file
288 lib/silcclient/client.c.
290 * The sender of the file transfer request now provides also
291 the pointer (listener) for the key exchange protocol. If
292 the listener cannot be created then it sends empty key
293 agreement and lets the receiver provide the listener.
295 Added `local_ip' and `local_port' arguments to the
296 silc_client_file_send. If they are provided they are used,
297 if not then it will attempt to find local IP address, if
298 not found or bind fails then the remote client will provide
301 Affected files are lib/silcclient/client_ftp.c and
302 lib/silcclient/silcapi.h.
304 * Extended the FILE SEND command to support defining the
305 local IP and port for key exchange listener. They are
306 optional. Affected file irssi/src/silc/core/silc-servers.c.
308 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Defined to WHOIS command reply the sending of fingerprint
311 of the client's public key (if the proof of posession of the
312 corresponding private key is verified by the server).
313 Updated to the protocol specification.
315 * Added support of receiving the client's public key's
316 fingerprint in command reply in client library. Affected
317 file is lib/silcclient/command_reply.c, and
318 lib/silcclient/idlist.[ch].
320 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
322 * Do not send over 128 chars long nickname to the server
323 in NICK command. Affected file lib/silcclient/command.c.
325 * Do not send over 256 chars long channel names to the server
326 in JOIN command. Affected file lib/silcclient/command.c.
328 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Assure that silc_server_close_connection cannot be called
331 twice for same socket context. Affected file is
334 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
336 * Send error message to application if opening file for
337 writing during file transfer fails. Affected file is
338 lib/silcclient/client_ftp.c.
340 Remove all file transfer sessions for a client that we're
341 removing from ID cache.
343 Affected file is lib/silcclient/client_ftp.c.
345 * Fixed silc_net_addr2bin to return correct address. Affected
346 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
348 * Fixed file transfer session removing on signoff notify.
349 Affected file irssi/src/silc/core/silc-servers.c.
351 * Added the SilcClientFileError to be returned in the monitor
352 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
353 Affected file lib/silcclient/silcapi.h.
355 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
357 * Fixed a crash in silc_client_ftp_free_sessions and
358 silc_client_ftp_session_free_client. Affected file
359 lib/silcclient/client_ftp.c.

362 to indicate if the server entry is disabled. Affected file
363 silcd/idlist.h, silcd/command[_reply].c.
365 * SILC server adds now /var/run/silcd.pid everytime it is
366 started. Affected file silcd/silcd.c.
368 * Added silc_server_packet_send_clients to send a packet to
369 the provided table of client entries. Affected file
370 silcd/packet_send.[ch].
372 * Fixed a crash in client resolving in client_prvmsg.c in
373 client library. Affected file lib/silcclient/client_prvmsg.c.
375 * Do not actually remove the client directly from ID cache
376 during SERVER_SIGNOFF, but invalidate it. This way we
377 preserve the WHOWAS info for the client. Affected file
380 * Fixed SERVER_SIGNOFF notify handling in the server. The
381 server is now able to process incoming SERVER_SIGNOFF notify
382 for a server that it doesn't even know about. It will remove
383 the clients provided in the notify. Affected file
384 silcd/packet_receive.c.
386 * Check for partial packet in data queue after every packet that
387 was found from the queue. Return and wait for more data if
388 there is partial data in queue. Affected file is
389 lib/silccore/silcpacket.c.
391 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

399 * Check that newsize in silc_buffer_realloc is larger than
400 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
402 * Added better monitor of file transfers. It now monitors
403 key agreement protocol during the file transfer too. Added
404 error reporting too. Affected files
405 irssi/src/silc/core/silc-servers.c,
406 irssi/src/fe-common/silc/module-formats.[ch].
408 * Wrote a help file for FILE command.
410 * Added silc_rng_global_get_byte_fast to get not-so-secure
411 random data as fast as possible. Random data is read from
412 /dev/urandom if available and from the SILC RNG if not
413 available. It is used in padding generation. Affected file
414 lib/silccrypt/silcrng.[ch].
416 * All packets in client library are now processed synchronously.
417 Optimized packet processing a lot. Affected file
418 lib/silcclient/client.c.
420 * All server connection packets are processing synchronously
421 now in server, to optimize packet processing. Affected file
424 * Include files are installed now only in Toolkit distribution
425 if make install is given. Affected files: all Makefile.am's.
427 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Assure that silc_client_notify_by_server_resolve does not
430 resolve the client information multiple times. If it cannot
431 be found by the first it cannot be found at all. Affected
432 file lib/silcclient/client_notify.c.
434 * Fixed WHOWAS command reply calling. Affected file
435 lib/silcclient/command_reply.c.
437 * Removed all references to silc_idlist_get_client from the
438 Irssi SILC client since that call is internal call used by
439 the library. The Irssi SILC client will use now client
440 retrieval functions found in silcapi.h.
442 * Fixed a bug in resolving nickname info before sending
443 private message. It used freed memory. Affected file
444 irssi/src/silc/core/silc-servers.c.
446 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
448 * Assure my_channels statistics cannot go negative in server.
449 Affected files silcd/server.c, silcd/server_util.c.

457 * Win32 Toolkit changes. Affected files
458 win32/silc.dsw, win32/libsilc/libsilc.def,
459 win32/libsilcclient/libsilc.def,
460 lib/silcutil/silcutil.c, and
461 lib/sftp/sftp_fs_memory.c.
463 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Added silc_net_localip to return local host's IP address.
466 Affected file lib/silcutil/silcnet.[ch].
468 * If key exchange or rekey protocol is active for a connection
469 parse all packets syncronously since there might be packets
470 in packet queue that we are not able to process without first
471 processing packets before them. Affected file silcd/server,
472 lib/silcclient/client.c.
474 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
475 whether library should continue processing the packet.
476 Affected file lib/silccore/silcpacket.h.
478 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
479 SilcSFTPMonitorData to SFTP server to monitor various
480 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

516 * Do not crash in /KEY if client is not connected. Affected
517 file irssi/src/silc/core/silc-channels.c.
519 * Added SilcClientStatus field to the SilcClientEntry in the
520 lib/silcclient/idlist.h.
522 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
523 is incomplete and is being resolved, it won't be resolved
526 Make sure also that USERS command reply does not resolve
527 twice information. Affected file is
528 lib/silcclient/command_reply.c.
530 Make sure that silc_client_get_clients_by_list does not
531 resolve twice same information.
533 * Check for valid client->id in the silc_server_free_client_data.
534 Affected file silcd/server.c.
536 * Fixed /GETKEY nick@server not to crash if the server entry

544 * Better checks for non-printable chars in nick added.
545 Affected file silcd/command.c.
547 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Call the silc_server_udpate_servers_by_server in the
550 primary router that comes back online in the backup resuming
551 protocol. Otherwise it routes packets wrong. Affected file
552 silcd/server_util.[ch], silcd/server_backup.c.
554 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
557 lib/silcutil/silcbuffmt.[ch].
559 * Redefined the SILC packet header to include the padding
560 length. Affected file lib/silccore/silcpacket.[ch].
562 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
563 length for maximum padding up to 128 bytes). Affected
564 file lib/silccore/silcpacket.h.
566 * Removed all backwards support for old 0.5.x MAC thingies.
567 The SILC packet header change makes it impossible to be
568 backwards compatible.
570 * Send the ENDING packet with timeout in the backup resuming
571 protocol. This is to assure that all routers has connected
572 to the primary router. Affected file silcd/server_backup.c.
574 * Changed the RNG to take the first IV from random data. It
575 used to take it from zero actually. Changed the RNG also
576 to use /dev/urandom during session. /dev/random is used
577 in initialization. Affected file lib/silccrypt/silcrng.[ch].
579 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
581 * Changed the SILC packet header to have the first two bytes
582 (the packet length) encrypted. Affected files aroung the
583 code tree, lib/silccore/silcpacket.[ch]. Removed the
584 SilcPacketCheckDecrypt callback. It is not needed anymore
585 since the silc_packet_receive_process will determine now
586 whether the packet is normal or special.
588 * Implemented the unidirectional MAC keys. Affected files
589 lib/silcske/silcske.c, silcd/protocol.c and
590 lib/silcclient/protocol.c.
592 * Implemented the packet sequence number to the MAC computation.
593 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
594 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
595 lib/silcclient/protocol.c.
597 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
599 * Allow backup router to announce servers. All servers
600 announced by backup router are added to the global list
601 automatically. Update hte server's socket to our primary
602 router also when backup router announces a server.
603 Affected file silcd/packet_receive.c.
605 * Do not update the client->router in the function
606 silc_server_udpate_clients_by_server if the client is on
607 global list. We might fail to find any specific server
608 for locally connected clients and local cell clients. They
609 should still use the `from' and not `to' as client->router.
610 This fixes backup router resuming protocol. Affected file
613 * Decrease channel statistics count only if the channel
614 deletion worked. Affected files are silcd/server.c and
617 * Added silc_server_update_servers_by_server to update origin
618 of all server entries. Used during backup router protocol.
619 Affected files silcd/server_util.[ch], silcd/server.c. and
620 silcd/backup_router.c.
622 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
623 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
624 silc_hmac_get_hash and silc_hmac_get_name. Affected file
625 lib/silccrypt/silchmac.c.
627 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Assure that router cannot reroute the same channel message
630 to the sender. Affected file silcd/packet_receive.c.
632 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Made better checks that the channel message is not sent
635 to the router it came from. Affected file is
636 silcd/packet_send.c. Fixed memory leak too.
638 * Announce informations for incoming router connection, but
639 only after checking if it is replaced by backup router.
640 Affected file silcd/packet_receive.c.
642 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Fixed the backup resuming protocol to work in multiple
645 router environment. Affected file silcd/server_backup.c.
647 * Route packet only to one router in the function
648 silc_server_packet_send_to_channel. Affected file is
651 * Fixed silc_server_send_notify_dest to set the broadcast
652 flag. Fixed the silc_server_send_notify_topic to actually
653 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
654 Affected file silcd/packet_send.c.
656 * Changed the SFTP Filesystem interface. Changed the
657 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
658 the filesystem operation function. The SilcSFTPFilesystem
659 is now a context that is allocated by all filesystem allocation
660 functions and it already includes the operations structure
661 and filesystem specific context. It is given as argument
662 now to the silc_sftp_server_start. This made the interface
663 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
664 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
666 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Changed the backup router adding and getting interfaces
669 in the server. The router that will be replaced by the
670 specified backup router is now sent as argument. Affected
671 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
674 * Added silc_net_addr2bin_ne to return the binary form of
675 the IP address in network byte order. Affected files
676 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
678 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Check for existing server ID in silc_server_new_server
681 and in silc_server_connect_to_router_final and remove the
682 old entry if it exists. Affected file silcd/packet_receive.c,
685 * Send the channel message always to only one router, either
686 in upstream or downstream. Affected file is
689 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Wrote the definition of the backup resuming protocol to the
692 protocol specification.
694 * Removed one redundant channel key generation from normal
695 server during joining procedure. Removed one redundant
696 channel key sending from server to router during joining
697 procedure. Affected file silcd/command.c.
699 * Made minor bugfixes to the backup router resuming protocol.
700 Affected file silcd/server_backup.c, server.c.
702 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
704 * Added --disable-asm configuration option. Affected files
705 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
708 * Implemented the backup resuming protocol that is used to
709 resume the primary router position in the cell after the
710 primary router comes back online. Affected files
711 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
712 and silcd/server_util.[ch].
714 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
716 * Sleep two (2) seconds after sending QUIT command to server.
717 Affected file lib/silcclient/command.c.
719 * Assure that if outgoing data buffer is pending do not force
720 send any data. Affected file silcd/packet_send.c.
722 * Assure that if outgoing data buffer is pending do not force
723 send any data. Affected file lib/silcclient/client.c.
725 * Implemented the backup router support when the primary router
726 goes down. The servers and routers can now use the backup
727 router as new primary router without loosing connectivity.
729 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
731 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
732 in the server to indicate disabled entry. All data read
733 from the connection will be ignored and no data is sent
734 for entry that is disabled. Affected files are
735 silcd/idlist.h, silcd/server.c.
737 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
739 * Created SFTP client and server test programs in the
740 lib/silcsftp/tests directory.
742 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
744 * Implemented memory filesystem (virtual filesystem) for
745 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
748 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
750 * Implemented the SFTP (SSH File Transfer Protocol) to the
751 lib/silcsftp. It includes SFTP client and SFTP server
754 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Moved lib/silccore/silcprotocol.[ch] to the
757 lib/silcutil library.
759 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
760 take variable argument list pointer as argument. Affected
761 file lib/silcutil/silcbuffmt.[ch].
763 * Added silc_buffer_set function that is used to set data
764 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
765 Affected file lib/silcutil/silcbuffer.h.
767 * Changed various routines in the core library to use the new
768 silc_buffer_set instead of allocating new buffer only for
771 * Added 64-bit value formatting and unformatting support to the
772 silc_buffer_[un]format routines. Affected file is
773 lib/silcutil/silcbuffmt.[ch].
775 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
776 to includes/bitmove.h.
778 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
780 * Fixed channel user mode saving in client library. Affected
781 file lib/silcclient/command[_reply].c.
783 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
785 * Defined the file transfer to the SILC Protocol. Added
786 new packet type SILC_PACKET_FTP and defined File Transfer
787 Payload. The mandatory file transfer protocol is SFTP
788 (SSH File Transfer Protocol). Affected file in addition
789 of the internet draft is lib/silccore/silcpacket.h.
791 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
792 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
793 is used as part of backup router protocol when the primary
794 router of the cell is back online and wishes to resume
795 the position as primary router.
797 * Redefined the MAC generation keys in the protocol. The
798 same key is not used anymore in both direction. Both
799 direction will now use different keys for sending and
800 receiving. This fixes a potential security flaw. This
801 change causes incompatibilities in the protocol.
803 * Redefined also the MAC computation from the packet.
804 An packet sequence number is now added to the MAC
805 computation. This prevents possible replay attacks against
806 the protocol. This change too causes incompatibilities
809 Added `sequence' field to the SilcPacketContext to hold
810 the current sequence number for the packet.
812 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
814 * Added `created' field to the SilcIDListData in the file
815 silcd/idlist.h to indicate the time when the entry was
818 * Added `created' field to the SilcChannelEntry too. Affected
821 * Added `creation_time' aguments to all the announcement functions
822 in the server. If it is provided then only the entries that
823 was created after the provided time frame are actually
824 announced. Affected file silcd/server.[ch].
826 * The protocol says that the Channel ID's IP address must be
827 based on the router's IP address. Added check for this in
828 the silc_server_new_channel when processing incoming New Channel
829 Payload. Affected file silcd/packet_receive.c.
831 * Print out the correct version with --version in SILC client.
832 Affected file irssi/src/silc/core/silc-core.c.
834 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Fixed WHOWAS command to check for completnes of the client
837 entry always, not just when the command is coming from client.
838 Affected file silcd/command.c.
840 * Added new function silc_server_packet_queue_purge to purge the
841 outgoing data queue to the network. After the function returns
842 it is guaranteed that the outgoing packet queue is empty.
843 Affected file silcd/packet_send.[ch].
845 * Purge the outgoing packet queue in the rekey protocol's final
846 callback to assure that all rekey packets go to the network
847 before quitting the protocol. Affected file silcd/server.c.
849 * Added silc_client_packet_queue_parse as similar function as
850 in server to the client library. The affected file is
851 lib/silcclient/client.c.
853 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
855 * Splitted silcd/server.c and created silcd/server_util.[ch]
856 for utility functions.
858 * Added new socket flag SILC_SF_DISABLED to indicate that the
859 connection is open but nothing can be sent to or received from
860 the connection. Affected file lib/silcutil/silsockconn.[ch].
861 The checking for disabled socket is checked in the low level
862 silc_socket_write and silc_socket_read functions.
864 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Allow only nicknames and channel names that fits into the
867 7-bit unsigned char ASCII set. Affected file silcd/command.c.
869 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
871 * When processing JOIN command reply in server check that if
872 the channel exists in our global list we'll move it the local
873 list. Affected file silcd/command_reply.c.
875 * Fixed the check whether client is joined on the channel already
876 in JOIN command. Affected file lib/silcclient/command.c.
878 * Fixed the JOIN command reply to check whether the channel
879 already exists. Affected file lib/silcclient/command_reply.c.
881 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Added silc_ske_status_string to map the SKE error numbers
884 to readable strings. The affected files are
885 lib/silcske/silcske[_status].[ch].
887 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
889 * Do not show the private channels on the WHOIS channel list
890 as it is not allowed by the protocol. The affected file is
893 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
895 * Assure that the packet length digged from the actual packet
896 is something sensible in the silc_packet_decrypt_rest_special
897 in lib/silccrypt/silcpacket.c.
899 * Free and NULL the allocated pointer in silc_hmac_alloc if
900 the HMAC allocation fails. The affected file is
901 lib/silccrypt/silchmac.c.
903 * Print the selected security properties to the log files in
904 the server. Affected file silcd/protocol.c.
906 * Add SKE's reference counter even if calling the completion
907 callback manually. Otherwise it goes negative, although it
908 does not cause any problems. The affected file is
909 lib/silcske/silcske.c.
911 * Remove the client entry with short timeout after giving the
912 KILL command. Affected file lib/silcclient/command.c.
914 * Fixed to send error reply in WHOIS and IDENTIFY commands in
915 case all found clients are already disconnected (WHOWAS would
916 found them) in the server. Affected file silcd/command.c.
918 * Update the last_receive (time of last data received) to be
919 updated only when received private or channel message so that
920 the idle time showed in WHOIS makes more sense.
922 * Added boolean field `valid' in to the SilcClientEntry in the
923 client library to indicate whether the entry is valid or not.
924 This fixes the nickname change bug on channel when changing
925 the nickname to be same than the old (like nick to Nick) the
926 nickname formatter doesn't set the new nick anymore to Nick@host.
927 Affected file lib/silcclient/idlist.[ch].
929 * Now actually fixed the nickname changing on disconnection.
930 Added new function silc_change_nick to the Irssi SILC Client.
931 Affected file irssi/src/silc/core/client_ops.c,
932 irssi/src/silc/core/silc-nicklist.[ch].
934 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Check that the public key exists in the GETKEY command before
937 trying to encode it. Affected file silcd/command.c.
939 * Print some notifications on received public keys with GETKEY
940 command in the Irssi SILC Client. Affected files are
941 irssi/src/fe-common/silc/module-formats.[ch],
942 irssi/src/silc/core/client_ops.c.
944 * Use IDENTIFY command to resolve the server information in the
945 GETKEY command instead of INFO command. Affected file
946 lib/silcclient/command.c.
948 * All command reply functions in the client library now calls
949 the pending command reply callbacks even if an error has
950 occurred. The server has done this a long time and now it was
951 time to move the client library to this as well. Now all
952 errors can be delivered back to the pending command reply
953 callbacks if necessary. Affected files are
954 lib/silcclient/command[_reply].[ch].
956 * Change the nickname on disconnection back to the username
957 because in reconnect the server will enforce it to it anyway.
958 Affected file irssi/src/silc/core/silc-servers.c.
960 * Fixed a config file parsing bug in the Irssi SILC client.
961 Affected file irssi/src/silc/core/clientconfig.c.
963 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
965 * When printing the channel mode on JOIN, verify that the
966 channel key and channel's HMAC are valid. Affected file
967 irssi/src/silc/core/client_ops.c.
969 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
972 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
973 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
975 * Removed channel key rekey task deleting from the function
976 silc_server_save_channel_key. Affected file silcd/server.c.
977 Added explicit timeout task context instead that is used to
978 delete the task if we are registering a new task before the
979 new task has elapsed.
981 * When channel key rekey occurs the client library now saves
982 the old channel key for a short period of time (10 seconds) and
983 is able to use it in case some is still sending channel
984 messages encrypted with the old key after the rekey. Affected
985 file lib/silcclient/[idlist.h|client_channel.c].
987 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Added check to the silc_server_new_id_real to not accept
990 new ID if it is the sender's own ID. Affected file is
991 silcd/packet_receive.c.
993 * Assure that we do not announce ourself or the one we've
994 sending our announcements when we're router and are announcing
995 servers to our primary router. Affected file silcd/server.c.
997 * Fixed silc_server_command_identify_check_client to assemble
998 correct WHOIS packet. It send corrupted WHOIS packet and
999 caused problem with router to router connections. Affected
1000 file silcd/command.c.
1002 Fixed also silc_server_command_whois_check the same way
1003 as for the IDENTIFY command.
1005 * Added new SilcIDListStatus to the server in the SilcIDListData
1006 structure. The status now includes the current status of
1007 the entry (like registered, resolved etc.). Affected file
1008 silcd/idlist.[ch]. Defined a bunch of different status types
1009 as well. This replaced the old boolean registered field as well.
1011 Added resolve_cmd_ident field to the SilcClientEntry structure
1012 too so that if the entry is for example being resolved so
1013 another command may attach to the same pending command reply
1014 without requiring to resolve the same entry again. This concept
1015 should optimize the WHOIS and the IDENTIFY resolving under
1016 heavy load by taking away unnecessary resolving for entries
1017 that are being resolved already.
1019 Added support for adding multiple pending commands for one
1020 command idenfier. Affected file silcd/command[_reply].[ch].
1022 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1023 before deleting the data. Otherwise the hash table will have
1024 freed data in comparison functions. Affected file is
1025 silcd/command_reply.c.
1027 * Fixed silc_idlist_replace_client_id to add the new entry to
1028 the cache with NULL nickname. Otherwise there will be invalid
1029 memory as the nickname after the nickname is freed. Affected
1030 file silcd/packet_receive.c.
1032 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1033 saved into wrong slots because the previous number of entries
1034 was not taken into account. Affected file silcd/idlist.c.
1035 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1037 * If we are router and we receive JOIN notify to a channel that
1038 does not have any users then notified client is marked as the
1039 channel founder, as it is it. The affected file is
1040 silcd/packet_receive.c
1042 * Added to the extended hash table API's table_del_*ext functions
1043 the destructor as argument too, so that the caller can decide
1044 which destructor to use or whether to use destructor at all.
1045 Affected file lib/silcutil/silchashtable.[ch].
1047 * Fixed ID Cache purging. It actually deleted the entries from
1048 the hash table after the data was freed. The hash table ended
1049 up comparing freed memory. The affected file is
1050 lib/silccore/silcidcache.c.
1052 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Fixed Irssi SILC client's KILL command's HELP syntax.
1056 * The USERS command now resolves the detailed user information
1057 if the userinfo field is missing. Affected file is
1058 lib/silcclient/command_reply.c.
1060 * Do not print error in silc_file_read if the read file does
1061 not exist. Just silently return NULL. Affected file is
1062 lib/silcutil/silcutil.c.
1064 * Fixed the silc_log_output to not wine about NULL filename
1065 and to not create some bogus " " filename. Affected file is
1066 lib/silcutil/silclog.c.
1068 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Fixed various printing bugs on the user interface in the
1071 Irssi SILC Client. Minor changes that were forgotten from
1074 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * Fixed the configure.in.pre and the compilation and distribution
1077 environment to support the new autoconf 2.52. That version is
1078 now required to compile the CVS trunk.
1080 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1083 to generally parse user@fqdn format strings. Affected file
1084 lib/silcutil/silcutil.c.
1086 * Added nickname_format and nickname_force_format fields to the
1087 SilcClientParams structure. The first one defines the format
1088 for the nicknames that the library will enforce if the receives
1089 multiple same nicknames. The second one is boolean value and
1090 can be used to force the library to always enforce the format
1091 to the nicknames regardles whether there are multiple nicknames
1092 or not. This configurable formatting was employed to flexibly
1093 support accessing multiple nicknames from the user interface.
1094 The userinterface can now set the nicknames to what ever format
1095 they prefer. Affected file lib/silcclient/silcapi.h.
1097 Added function silc_client_nickname_format to the file
1098 lib/silcclient/idlist.c. It performs the nickname formatting.
1100 Added new field `hostname´ to the SilcClientEntry context.
1101 It holds the hostname of the client. Affected file is
1102 lib/silcclient/idlist.h.
1104 * Irssi SILC Client sets the nicknames in nick@hostn format.
1105 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1106 irssi/src/silc/core/silc-core.c.
1108 The WHOIS printing now also shows both the real nickname and
1109 the formatted nickname so that user knows how to access the
1110 user if there are multiple same nicknames cached. Affected
1111 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1112 printing formatting too to take the hostname now as a separate
1113 argument. The Affected file is
1114 irssi/src/fe-common/silc/modules-formats.[ch].
1116 * Changed the silc_client_get_clients_local to accept the formatted
1117 nickname as argument. It accepts the real nickname too but the
1118 formatted nickname can be used to find the true entry from
1119 multiple entries. Affected file lib/silcclient/silcapi.h and
1120 lib/silcclient/idlist.c.
1122 * Added nickname_format_parse field to the SilcClientParams.
1123 It is a callback function provided by the application to parse
1124 the nickname out of the formatted nickname string. The library
1125 calls it to get the nickname from the formatted string. Since
1126 the application generally knows better the format of the nickname
1127 string it parses it instead of the library, even though library
1128 encodes the formatted string. If the callback function is not
1129 provided then the library will use the string as is. The
1130 affected file is lib/silcclient/silcapi.h.
1132 * All the nickname strings passed to the client library in
1133 commands are now expected to be formatted nickname strings.
1134 If the command does not support the formatted nickname string
1135 it will assume that the sent string is the actual nickname.
1136 Affected file lib/silcclient/command.c.
1138 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Added public key authentication support to OPER and SILCOPER
1141 commands in the client library. Affected file is
1142 lib/silcclient/command.c.
1144 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1146 * Changed the get_auth_methdod client operation to be asynchronous.
1147 It can be async if the application resolves the authentication
1148 method from the server during the negotiation. Added new
1149 SilcGetAuthMeth completion callback that the application will
1150 call after resolving the authentication method.
1152 Added function silc_client_request_authentication_method that
1153 the application can use to resolve the authentication method
1154 from the server. Added also SilcConnectionAuthRequest callback
1155 that the library will call after the server has replied. The
1156 application can call this function if it does not know the
1157 current authentication method.
1159 Affected files are lib/silcclient/client.c and
1160 lib/silcclient/silcapi.h.
1162 * The Irssi SILC client now automatically resolves the authentication
1163 method incase any configuration information is not present (and
1164 currently there never is). The affected file is
1165 irssi/src/silc/core/client_ops.c.
1167 * Fixed public key authentication from the client library.
1168 Affected file lib/silcclient/protocol.c. Changed also the
1169 protocol specification about the public key authentication in
1170 the connection authentication protocol. The actual data to be
1171 signed is now computed with a hash function before signing.
1173 * Fixed the public key authentication from the server as well.
1174 Affected file silcd/protocol.c.
1176 * Removed the mlock()'s from the memory allocation routines.
1177 Affected file lib/silcutil/silcmemory.c. The ./configure does
1178 not check anymore for the mlock(). Affected file is
1181 * Fixed USERS command in server to allow the execution of the
1182 command for private and secret channels if the client sending
1183 the command is on the channel. Affected file silcd/command.c.
1185 * Fixed silc_client_get_clients_local to return the clients
1186 count correctly. It could return wrong value. Affected file
1187 lib/silcclient/idlist.c.
1189 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1192 types. The assembler optimizations seemed not to like 64-bit
1193 data types. The assmebler optimizations thus are now enabled
1194 also for BSD systems as opposed to only enable them for Linux.
1196 * Do not check for threads at all on BSD systems. Affected
1197 file configure.in.pre.
1199 * Removed -n and -h options from the Irssi SILC Client since
1200 they are not used in silc.
1202 * Fixed the prime generation to assure that the first digit
1203 of the generated random number is not zero since our conversion
1204 routines does not like number strings that starts with zero
1205 digit. If zero digit is seen the random number is regenerated.
1206 This caused some corrupted RSA keys when the zero first digit
1207 was met. Affected file lib/silcmath/silcprimegen.c.
1209 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1211 * Fixed WIN32 configuration in the ./configure script.
1212 Fixed to include xti.h on environments that has it.
1213 Patches by Carsten Ilchmann and andrew.
1215 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Changed the silc_id_create_client_id to be collision
1218 resistant. It is now assured that there cannot be created
1219 two same client ID's. I suspect that some weird bugs in
1220 the server were actually caused by duplicate Client IDs.
1221 Affected file silcd/serverid.[ch]. A router receiving
1222 new ID now also assures and informs the sending server
1223 if the ID caused collision.
1225 * Changed the silc_id_create_channel_id to also assure that
1226 there are no collisions.
1228 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Statement about ignoring the Mutual Authentication flag when
1231 performing rekey with PFS was a bit misleading. It is ignored
1232 if it was set in the initial negotiation, it cannot be even
1233 set in the rekey. Fixed in the ke-auth draft. Started the
1234 new versions of the protocol drafts in the doc/.
1236 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Fixed a bug in silc_client_command_identify_save when saving
1239 new channel information. The channel name was no duplicated
1240 and caused crash on exit. Affected file is
1241 lib/silcclient/command_reply.c.
1243 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * Fixed the getkey command handling in the server. Send just
1246 empty OK reply to the sender if the key could not be fetched
1247 (but everything else was ok, like the key just was not available).
1248 Changed the public key parameter to optional in the protocol
1249 specs so that empty OK reply can be sent. Affected file
1252 Added a message to Irssi SILC client to tell to user if the
1253 server did not return a public key.
1255 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Fixed a channel key regeneration bug. It registered new
1258 timeout tasks exponentially until all system resources were
1259 used. Affected file silcd/server.c.
1261 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Added the SILC Document generator to the scripts/silcdoc.
1264 It can be used to generate the Toolkit Reference Manual out
1265 of the source tree. Internally it will also use the RoboDoc
1266 generator now imported in util/robodoc.
1268 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Added couple of return's in rekey protocol if error orccurred
1271 during the protocol. The execution must be terminated.
1272 Affected file silcd/protocol.c. Also, terminate the protocol
1273 always with timeout.
1275 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * The client's Client ID was created initally from the wrong
1278 nickname (it could have been in format nick@host) in the
1279 silc_server_new_client. Affected file silcd/packet_receive.c
1281 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Added some SILC_LOG_ERROR's to various error conditions
1284 if client could not be added to ID cache. Affected files
1285 silcd/packet_receive.c and silcd/server.c.
1287 * When client's sock->user_data is freed, NULL also the
1288 client->router and client->connection pointers. Added check
1289 for these pointers being NULL to various places around the
1290 code. Affected file silcd/server.c.
1292 * Added client->data.registered == TRUE checks to various
1293 places around the code to assure that unregistered client's
1294 are not handled when it is not allowed. Affected file
1297 * Added `bool registered' fields to all
1298 silc_idlist_[server|client]_get_* routines to indicate whether
1299 the fetched client needs to be registered or not. Affected
1300 file silcd/idlist.[ch].
1302 * Add your own entry as registered to the ID cache in the
1303 server. Affected file server.c.
1305 * Fixed a bug in silc_server_new_server. The SilcServer was
1306 set as the new server's context instead of SilcServerEntry.
1307 This naturally caused some weird bugs.
1309 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Do not delete the channel rekey task when adding it
1312 for in silc_server_create_channel_key.
1314 * Changed the silc_server_create_channel_key to return
1315 TRUE or FALSE to indicate the success of the channel key
1318 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1320 * Fixed MSVC++ project files and added missing files to
1321 Makefiles under win32/.
1323 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Do not add TCP_NODELAY flag if the operating system
1326 does not have it defined. Affected files are
1327 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1329 * Fixed buffer overflow from Irssi SILC Client. Affected
1330 file irssi/src/fe-common/core/themes.c.
1332 * Fixed double free in client library in the file
1333 lib/silcclient/client.c when disconnecting from server.
1335 * Applied double free patch from cras to Irssi SILC client.
1336 Affected files irssi/src/core/[modules/expandos].c
1338 * Fixed the disconnection handling to Irssi SILC Client.
1339 The application must call silc_client_close_connection
1340 in ops->connect client operation in case of failure of
1341 the connection. Affected file is
1342 irssi/src/silc/core/client_ops.c.
1344 * Do not set sock->protocol to NULL in the function
1345 silc_client_close_connection after executing the protocol's
1346 final callback since the sock might not be valid anymore.
1347 Affected file lib/silcclient/client.c.
1349 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Do not enable SILC_THREADS if the linking with libpthread
1352 did not happen. Affected file configure.in.pre.
1354 * Added notion to protocol specification that server must
1355 verify the sent authentication payload with CMODE when
1356 setting the channel founder key. Implemented it to the
1357 server. Affected file silcd/command.c.
1359 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Added _EXTRA_DIST SILC distribution variable to the
1362 distributions file. It is used to conditionally add extra
1363 files or directories to the specific distribution. Affected
1364 files ./prepare, Makefile.am.pre and distributions.
1366 Removed the `_' from the start of the distribution names.
1369 * Added README.WIN32 for instructions to compile the Toolkit
1372 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Fixed a double free in disconnection in the server. Affected
1375 file is silcd/server.c.
1377 * Fixed the lib/silcske/groups.c to work now also with GMP
1378 MP library. The string conversion did not work when using
1379 specific base and the base is indicated in the string as well.
1381 * Created win32/ directory which now includes MSVC++ specific
1382 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1383 It will appear only in the toolkit distribution
1385 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Changed the key material distribution function in case when
1388 the hash output is too short. The data is now concatenated
1389 a bit differently than it used to. Made the change to the
1390 SKE protocol specification.
1392 * Added better GMP detection to configure.in.pre. A patch
1395 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1397 * Fixed a minor bug in SKE that might cause some problem on
1398 some platforms. Affected file lib/silcske/silcske.c.
1400 * Added the cookie checking for initiator in the SKE. It checks
1401 that the responder returns the sent cookie unmodified. The
1402 affected file is lib/silcske/silcske.c. Added new SKE
1403 error type INVALID_COOKIE that can be sent during the
1404 negotiation. Fixed some memory leaks as well.
1406 * Added the "invalid cookie" error message to Irssi SILC client's
1409 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Added `task_max' field to the SilcClientParams to indicate
1412 the maximum tasks the scheduler can handle. If set to zero,
1413 default values are used. Affected file lib/silcclient/silcapi.h.
1415 * Fixed memory leaks in silc_client_close_connection. Affected
1416 file lib/silcclient/client.c.
1418 * Added silc_client_del_client_entry to client library to free
1419 all memory of given client entry. Affected file is
1420 lib/silcclient/idlist.[ch].
1422 * Added new functions silc_client_del_channel and
1423 silc_client_del_server to delete channel and server entries.
1424 Affected file lib/silcclient/[silcapi.h/idlist.c].
1426 * Removed silc_client_del_client_by_id from silcapi.h.
1428 * Fixed the INFO command to return the server's own info
1429 correctly when querying by Server ID. Affected file is
1432 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Removed the non-blocking settings in WIN32 code in the
1435 silc_sock_[read/write] and added SleepEx instead. Affected
1436 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1437 of input data is now checked with FIONREAD and ioctlsocket.
1439 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1441 * Call silc_schedule_task_del_by_context in the
1442 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1443 Affected file lib/silccore/silcprotocol.c.
1445 * Call silc_protocol_cancel for active protocols in the
1446 silc_server_close_connection if the funtion
1447 silc_server_free_sock_user_data has not been called.
1448 Affected file silcd/server.c.
1450 * Generic tasks cannot be deleted using the del_by_fd
1451 task deleting function since generic tasks does not match
1452 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1454 * Added a notion to SILCOPER help file that the SILCOPER works
1455 only on router server, not on normal server.
1457 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Added for WIN32 support for the new scheduler as well.
1460 Affected file lib/silcutil/win32/silcwin32schedule.c.
1462 * Fixed the SHA1 implementation to work on various platforms.
1464 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1467 API. It is part of the scheduler now. Everything else is
1468 as previously but some functions has changed their names.
1469 Checkout the lib/silcutil/silcschedule.h for the interface.
1470 Updated all applications to use the new interface. Affected
1471 files are lib/silcutil/silcschedule.[ch].
1473 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1475 * Found a bug in the SKE implementation. The HASH value,
1476 specified by the protocol, was not computed correctly. The
1477 public key of the responder was not added to the computation
1478 even though it is mandatory. Affected file lib/silcske/silcske.c.
1479 This unfortunately causes incompatibilities with older
1480 clients and servers.
1482 * Added WIN32 specific network init and uninit functions:
1483 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1484 the Winsock2. Affected file lib/silcutil/silcnet.h and
1485 lib/silcutil/win32/silcwin32net.c.
1487 * Set the socket always to nonblocking mode on WIN32 after
1488 reading data or writing data. Affected file is
1489 lib/silcutil/win32/silcwin32sockconn.c.
1491 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Fixed various compilation problems under WIN32. Affected
1494 files lib/silcutil/win32/silcwin32thread.c and
1495 lib/silcutil/win32/silcwin32schedule.c.
1497 * Removed all _internal.h #includes from public header
1498 files. Internal headers must never be included from
1501 Removed also the lib/silcske/payload_internal.h file.
1503 * All include files that may be needed (public and some others
1504 included by the public headers) by application developers are
1505 now copied to the ./includes directory. It does not copy any
1506 internal headers. Affected file Makefile.defines.pre and all
1507 Makefile.am's under lib/ and subdirs.
1509 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Do not change the ~/.silc directory's permissions automatically.
1512 Affected file irssi/src/silc/core/clientutil.c.
1514 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Do not cancel the protocol in silc_server_close_connection
1517 it might cause recursion. Now cancelled in the function
1518 silc_server_free_sock_user_data. Affected file silcd/server.c.
1520 * Fixed the silc_server_remove_clients_by_server to regenerate
1521 the channel keys correctly finally. Added also new function
1522 silc_server_remove_clients_channels to actually do it.
1523 Affected file silcd/server.c.
1525 * Fixed the silc_server_new_channel to not crash by giving
1526 wrong router to the new channel. Affected file is
1527 silcd/packet_receive.c.
1529 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1532 which is given as argument to the silc_client_alloc now.
1533 It can be used to configure the client and set various parameters
1534 that affect the function of the client.
1536 * The USERS command in server did not check whether the channel
1537 is private or secret. Affected file silcd/command.c.
1539 * Added new argument to the USERS command in protocol specification.
1540 The USERS command now can take the channel name as argument
1541 as well. Added support for this in client and server and
1542 updated the protocol specs.
1544 * Completed the GETKEY command in client. It can be now used
1545 to fetch also servers public key not only some clients.
1546 Affected files lib/silcclient/command[_reply].c.
1548 * Added silc_client_get_server to return server entry by the
1549 server name. Affected files lib/silcclient/silcapi.h and
1552 * Redefined the IDENTIFY command in protocol specification to be
1553 more generic. It now can be used to query information about
1554 any entity in the SILC Network, including clients, servers and
1555 channels. The query may be based either the entity's name
1556 or the ID. Added support for this in both client and server.
1558 Affected files silcd/command.c and lib/silcclient/command.c
1559 and command_reply.c.
1561 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1562 the _from_client and _from_server functions. Affected file
1565 * Added silc_client_get_channel_by_id_resolve to the file
1566 lib/silcclient/silcapi.h to resolve channel information by
1567 its ID. Added also silc_client_get_channel_by_id that
1568 does not resolve it from the server.
1570 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Added SilcServerEntry context into the client library
1573 to represent one server. The INFO command now allocates
1574 these to save the resolved server info. For now on the
1575 client library will also keep information about servers,
1576 connected and resolved with INFO.
1578 The INFO command now allocates the SilcServerEntry context
1579 and saves the server info there. The COMMAND_REPLY in
1580 the INFO now returns the parameters to application in
1581 same order as defined in the protocol specification.
1583 The entries are cached in the client->server_cache.
1585 * The INFO command is now issued after received the Client ID
1586 from the server. Affected file lib/silcclient/client.c.
1588 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1589 to the application as the mode changer might be server.
1590 It is guaranteed that NULL is not returned anymore to the
1591 application. Affected file lib/silcclient/client_notify.c.
1593 The ID Type is now also passed to the application so that
1594 it can check whether the returned entry is SilcClientEntry
1597 Added new function silc_client_get_server_by_id to return
1598 the server entry by ID. Affected files are the
1599 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1601 * Do not create the channel in the Irssi SILC Client when issuing
1602 the JOIN command but when received the sucessful JOIN command
1603 reply. Otherwise the channel might get created even though we
1604 could not join it. The Affected file is
1605 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1607 * Fixed a channel joining bug in router. The router must also
1608 check the channel modes, invite and ban lists etc. when serving
1609 the JOIN command sent by normal server. Affected file is
1610 silcd/command.c. The router now resolves the client's
1611 information from the server who sent the JOIN command if it
1612 does not know it, and processes the JOIN command only after
1615 * Changed the SilcCommandCb to take new argument; void *context2.
1616 Affected file lib/silccore/silccommand.h
1618 The second argument in the command callbacks in the server now
1619 includes the SilcServerCommandReplyContext if the command was
1620 called as pending command callback from the command reply.
1621 Otherwise it is NULL. When called as pending the status of the
1622 command reply will be checked and if it was erronous the
1623 error will be sent to the original sender of the command.
1624 This way the client always receives the error messages even
1625 though the server was actually the one who received the error
1626 when it resent the command to router, for example. Affected
1627 files silcd/command[_reply].[ch].
1629 * Fixed sending WHOWAS command's error message to client if
1630 the requested client could not be found. It was missing.
1633 * Changed the CMODE and CUMODE commands reply arguments in the
1634 protocol specification. The Channel ID is now sent in both
1635 of the commands to identify the channel. Implemented this
1636 new feature to the client and server. Affected files
1637 lib/silcclient/command_reply.c and silcd/command.c.
1639 * Made better checks for invite and ban lists in the JOIN
1640 command in server. Affected file silcd/command.c.
1642 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * The server now performs the incoming host IP/DNS lookup
1645 using the silc_socket_host_lookup and thus does not block
1646 the server anymore. Affected file silcd/server.c.
1648 * Completed the multi-thread support for SILC Scheduler in
1649 the lib/silcutil/silcschedule.c.
1651 * Fixed the configure.in.pre to detect the pthread correctly
1654 * Fixed a deadlock in silc_task_queue_wakeup in the file
1655 lib/silcutil/silctask.c.
1657 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Added new function silc_schedule_wakeup that is used in
1660 multi-threaded environment to wakeup the main thread's
1661 schduler. It needs to be used when a thread adds a new task
1662 or removes a task from task queues. After waking up, the
1663 scheduler will detect the task queue changes. If threads
1664 support is not compiled in this function has no effect.
1665 Implemented the wakeup mechanism to both Unix and WIN32
1666 systems. Affected files are lib/silcutil/silcschedule.[ch],
1667 lib/silcutil/unix/silcunixschedule.c and the
1668 lib/silcutil/win32/silcwin32schedule.c.
1670 * Added new function silc_task_queue_wakeup to wakeup the
1671 scheduler by the specified task queue. Affected file
1672 lib/silcutil/silctask.[ch].
1674 * The silc_socket_host_lookup_start now wakes up the scheduler
1675 after adding the timeout task. Affected file is
1676 lib/silcutil/silcsockconn.c.
1678 * The silc_socket_host_lookup is synchronous now if the threads
1679 support is not compiled in. However, the callback is still
1680 called asyncronously through the scheduler, anyway. Affected
1681 file lib/silcutil/silcsockconn.c.
1683 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Added new function silc_socket_host_lookup to perform
1686 asynchronous IP and FQDN lookups for the socket connection.
1687 Affected files lib/silcutil/silcsockconn.[ch].
1689 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1691 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1692 that may or may not compile the mutex support in.
1694 Changed the silc_mutex_alloc interface. It allocates the
1695 mutex now to the sent pointer and returns TRUE or FALSE.
1697 Affected file lib/silcutil/silcmutex.h.
1699 * Wrote the SILC Task Queue interface to support multi-threads.
1700 Affected file lib/silcutil/silctask.[ch].
1702 * Wrote the SILC Scheduler to support multi-threads. Affected
1703 file lib/silcutil/silcschedule.c.
1705 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1708 in lib/silcutil/win32/.
1710 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Defined SILC Mutex API and SILC Thread API and implemented
1713 them for Unix. Affected files are
1714 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1715 lib/silcutil/unix/silcunixmutex.c and
1716 lib/silcutil/unix/silcunixthread.c.
1718 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Fixed the silc_server_remove_clients_by_server's channel
1721 key re-generation. The hash table handling was incorrect
1722 and would not work with many channels. Affected file is
1725 * Fixed some memory leaks around the server code.
1727 * Rewrote the silc_server_get_users_on_channel to support IPv6
1728 based Client ID's. Affected file silcd/server.c.
1730 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1731 specification. However, a separate document must be written
1732 to define the detailed signing procedure and the payload
1733 associated with the flag. Defined the flag to the
1734 lib/silccore/silcchannel.h as well.
1736 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Changed the dynamic tables to static size tables in the
1739 lib/silccrypt/silchmac.c.
1741 * Removed GCC dependencies from the code. A patch by cras.
1743 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Do not show the error "Error receiving packet bla bla"
1746 in server if it really was not an error (-2 means that reading
1747 is pending). Affected file silcd/server.c.
1749 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Fixed a possible crash in silc_server_remove_clients_by_server
1752 in silcd/server.c. Fixed there also some memory leaks.
1754 * Fixed the silc_idlist_replace_client_id. It could replace
1755 wrong key in the hash table. Affected file silcd/idlist.c.
1757 * Do not check whether there are global users on the channel
1758 if the channel->global_users is FALSE. Affected functions
1759 silc_server_remove_from_one_channel and
1760 silc_server_remove_from_channels in silcd/server.c. Also,
1761 do not check if the removed client is local as we can be
1762 sure that global client was not removed from the channel
1763 and checking for global users is not needed.
1765 * The silc_server_remove_clients_by_server now re-generates
1766 the channel keys correctly for those channels that had
1767 clients removed from them. Affected file silcd/server.c.
1769 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Found the reason of random crashes in the server. We weren't
1772 ignoring the SIGPIPE signal (which can be sent in write())
1773 and it crashed the server. Affected file silcd/silcd.c.
1775 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Assure that sock->user_data is not NULL in the function
1778 silc_server_packet_send in silcd/packet_send.c.
1780 * Disconnect the remote connection if it could not be added
1781 to any ID lists in the server. The affected file is
1784 * Check in silc_server_packet_send[_real/dest] that the
1785 socket is not disconnecting and ignore the data if it is.
1786 Affected file silcd/packet_send.c.
1788 * Define inline to __inline on native WIN32 compilation.
1789 Affected file includes/silcwin32.h.
1791 * Added some explicit type casts for inline code since MSVC
1792 require them. Affected files lib/silcutil/silcbuffer.h,
1793 lib/trq/silcdlist.h and lib/trq/silclist.h.
1795 * Print warning in log files from now on if the packet
1796 decryption fails. Affected file silcd/server.c.
1798 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Changed the `say' client operation's interface to accept
1801 new `type' argument to indicate the type of the message sent
1802 by the library. The application may filter the library's
1803 messages according the type. The affected file is the
1804 lib/silcclient/silcapi.h.
1806 * Added two new functions to lib/silcclient/silcapi.h:
1807 silc_client_del_client and silc_client_del_client_by_id.
1808 Affected file lib/silcclient/idlist.c.
1810 * Moved the clientincludes.h from includes/ to silc/ and
1811 serverincludes.h from includes/ to silcd/.
1813 * The modes for the CMODE and CUMODE are now passed as
1814 uint32 for application with COMMAND_REPLY. The affected
1815 file is lib/silcclient/command_reply.c.
1817 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * /WHOIS without arguments shows client's own information.
1820 Affected file lib/silcclient/command.c.
1822 * Changed PING to not accept any arguments. The specs
1823 says that client can ping only the connected server so
1824 requiring an argument is not needed. Affected file is
1825 lib/silcclient/command.c.
1827 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Fixed a fatal bug in private message sending and reception
1830 encryption and decryption when using private message keys.
1831 The implementation was incorrect and did not follow the
1832 specification. It causd that some of the message were
1833 lost since it did not use the sending and receiving keys
1834 as the protocol suggests. This has been fixed and will cause
1835 incompatibilities with older clients when sending private
1836 message encrypted with private message keys. Affected files
1837 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1838 and various other in Irssi SILC Client.
1840 Added `responder' boolean argument to the functions
1841 silc_client_add_private_message_key[_ske] to indicate when
1842 the key is added as responder or initiator of the key
1845 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Removed the silc_ske_check_version function and created
1848 a SilcSKECheckVersion callback. Added also a function
1849 silc_ske_set_callbacks that is now used to set all SKE
1850 callbacks. The callback functions are not given to
1851 the SKE functions anymore, but this function is used to
1854 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1856 * Added `silc_version' argument to the silc_client_alloc
1857 to define the version of the application for the library.
1858 The library will use the version string to compare it
1859 against the remote host's (usually a server) version
1860 string. Affected file lib/silcclient/silcapi.h
1862 * Added the KE protocol context to Key Agreement context
1863 in client library so that we can abort the SKE if it
1864 is in process when we get timeout. Affected file is
1865 lib/silcclient/client_keyagr.c.
1867 * Do not resolve the client ID forever if it returns in the
1868 first time that such client does not exist. This was done
1869 for example with private message. Affected file is
1870 lib/silcclient/client_prvmsg.c.
1872 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Do not add regex.h for WIN32. The affected file
1875 includes/silcincludes.h.
1877 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1878 not work yet 100%. It generates the DLL's automatically
1879 when compiling with --with-win32 under cygwin.
1881 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * lib/contrib/regex.c is not compiled on WIN32.
1885 * Added silc_net_get_socket_opt function to the
1886 lib/silcutil/silcnet.h.
1888 * Added includes/silcwin32.h for WIN32 specific includes
1891 * Do not use ptime structure or any of the posix process
1892 functions on WIN32 in lib/silccrypt/silrng.c.
1894 * Added silc_gettimeofday to provide generic function
1895 for struct timeval on all platforms. Added the function
1896 to lib/silcutil/silcutil.h.
1898 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1901 library as they clearly belong there. As a plus side we
1902 can make the actual socket connection routines platform
1905 Added also new generic function silc_socket_read and
1906 silc_socket_write (that used to be silc_packet_[read/write].
1907 The implementation of these are platform specific.
1909 * Added WIN32 specific routines of silc_socket_[read/write]
1910 to lib/silcutil/win32/silcwin32sockconn.c.
1912 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Added preliminary support for native WIN32 compilation under
1915 cygwin (using the -mno-cygwin option for GCC) to the
1916 ./configure.in.pre. The --with-win32 now prepares the
1917 compilation for native WIN32.
1919 * Rewrote the SILC Scheduler interface in the file
1920 lib/silcutil/silcschedule.h. The scheduler is now context
1921 based and does not have anymore any global static scheduler.
1922 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1923 and created lib/silcutil/win32 directory for WIN32 based
1926 * Added Unix specific network routines to the
1927 lib/silcutil/unix/silcunixnet.c and the old
1928 lib/silcutil/silcnet.c includes now only generic routines.
1930 Added WIN32 specific network routines to the
1931 lib/silcutil/win32/silcwin32net.c.
1933 * Added Unix specific utility functions from the
1934 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1936 * Added WIN32 SILC Scheduler to the file
1937 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1940 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Do not handle JOIN notify in the server if the target client
1943 is not registered (idata->registered == FALSE). The affected
1944 file is silcd/packet_receive.c.
1946 * Update the nickrec->founder in event_cumode in the Irssi SILC
1947 client. Affected file irssi/src/silc/core/silc-channels.c.
1949 * Fixed the CUMODE_CHANGE notify handling in the server when
1950 server and router are announcing their clients on channels.
1951 Now the mode changes are saved and notified correctly. The
1952 affected file is /silcd/packet_receive.c.
1954 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1955 They really did not replace the cache entry in the ID Cache.
1956 Now they do that. Affected file silcd/idlist.c.
1958 * Fixed the KICK notify handling in the Irssi SILC client to
1959 update the channel records so that the kicked client does not
1960 appear to be on the channel. The affected file is
1961 irssi/src/silc/core/silc-channels.c.
1963 * Always update the conn->current_channel when executing command
1964 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1966 * Fixed the KILL notify handling in Irssi SILC client to remove
1967 the killed client on all channels.
1969 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Fixed the silc_parse_command_line to remove extra spaces
1972 from the start and end of the arguments. Affected file is
1973 lib/silcutil/silcutil.c.
1975 * Cancel and free any active protocol in the function
1976 silc_server_close_connection. Affected file silcd/server.c.
1978 * Cancel and free any active protocol in the function
1979 silc_client_close_connction. Affected file is
1980 lib/silcclient/client.c.
1982 * Do not execute the KILL command for clients that are in
1983 history (ie. they are not in the network). Affected file is
1986 * Fixed KILL notify handling, client does not crash anymore.
1987 Affected file irssi/src/silc/core/silc-channels.c.
1989 * Reduced the default packet buffer size from 2048 to 1024 in
1990 lib/silccore/silcpacket.c.
1992 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1993 counter to the SKE context that is incresed when the SKE library
1994 performs async operation outside the library. If the outside
1995 process frees the SKE context and FREED status will be set
1996 and the library will detect after the sync operation that the
1997 libary is freed. The affected files are
1998 lib/silcske/silcske[_status].[ch].
2000 * Resolve the client entry information in the function
2001 silc_client_channel_message to assure that NULL pointer is not
2002 passed as client entry to the application. */
2004 * Fixed the task timeout calculation to assure that there is
2005 never negative timeouts. The affected file is
2006 lib/silcutil/silcschedule.c.
2008 * Fixed the channel user mode notification sending in server.
2009 It was sent point-to-point to the router (or to server by router)
2010 but it needs to be destined to a channel. The routines now
2011 supports sending the channel user mode notifys to the channels
2012 when announcing clients and channels. Affected files are
2013 silcd/server.c and silcd/packet_receive.c.
2015 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2016 It did not actually replace the old channel entry in the cache.
2017 Affected file lib/silcclient/client_notify.c.
2019 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Fixed a possible crash in silc_packet_send_prepare. It now
2022 assures always that there is enough space in the buffer and
2023 at the tail area of the buffer (for MAC).
2025 Fixed the inbound buffer reallocation in silc_packet_read.
2026 It was old code and did not handle the reallocation correctly.
2029 The affected file is lib/silccore/silcpacket.c.
2031 * Fixed buffer overflow in silc_parse_nickname in the file
2032 lib/silcutil/silcutil.c.
2034 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * make install generates new server keys only if there is not
2039 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2042 Added check that if the NOREPLY is set then we will not send
2043 the away message. This avoids infinite loop of away messages
2044 if both clients are away. The affected file is
2045 lib/silcclient/client_prvmsg.c.
2047 * Fixed client crash if /NICK was given without arguments.
2048 Affected file lib/silcclient/command.c.
2050 * Server does not send the invite list in INVITE command back
2051 to the client if the list was not altered. Added this notion
2052 to the protocol spec as well. Affected file silcd/command.c.
2054 Fixed possible crash in INVITE command by checking the
2055 value of silc_server_get_client_route command.
2057 * Fixed the INVITE notify type handling. The arguments are now
2058 taken in correct order and client does not crash. The affected
2059 file is irssi/src/silc/core/silc-channels.c.
2061 Removed the "Inviting xxx to channel" message from the
2062 client library away and let the application handle it.
2063 Affected file lib/silcclient/command.c. Added that message
2064 to Irssi SILC client's message formats.
2066 * Fixed CMODE command crash in client. It now checks the
2067 amount of arguments correctly and does not crash. The affected
2068 file is lib/silcclient/command.c.
2070 * Do not create new channel automatically in silc_channels_join
2071 but check whether the channel by that name already exists.
2072 Affected file irssi/silc/core/silc-channels.c.
2074 * Do not send the SERVER_SIGNOFF to router if the disconnected
2075 entity was the router. Affected file silcd/server.c.
2077 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2078 SILC client as it was missing from there.
2080 Added the handling of the KICK notify to the Irssi SILC client
2081 as it was missing. Added "you have been kicked" message to
2082 Irssi SILC client's message modules formats.
2084 Added the handing of the KILL notify to the Irssi SILC client
2085 as it was missing. Added the kill message module formats
2088 The affected file is irssi/src/silc/core/silc-channels.c.
2090 * The router did not save the channel mode the server announced.
2091 Affected file silcd/packet_receive.c.
2093 * Fixed a possible crash in INFO command in server. If the
2094 server did not provide the server info it crashed. Affected
2095 file silcd/command.c.
2097 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Fixed the GETKEY command in the server to check also the
2100 global list. Otherwise the GETKEY would not work correctly
2101 in normal SILC server. Affected file silcd/command.c.
2103 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * Fixed GETKEY crash, it crashed if the command did not succseed.
2107 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2110 is now real and not just an macro interface to GMP.
2112 Removed the entire GMP from the source tree and imported new
2113 NSS MPI library instead. Reason for removing GMP is that it is
2114 extremely large and compiles extremely slow. The NSS MPI
2115 is only a few files and compiles in less than 10 seconds.
2116 The speed is also about the same as GMP. The MPI is imported
2117 to lib/silcmath/mpi.
2119 If the system has GMP installed we will still use the GMP.
2120 If it is not then the NSS MPI will be compiled.
2122 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Merged a long nickname (127 characters long) crash bugfix from
2125 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2127 * Merged a freed memory reference bugfix from Irssi CVS tree.
2128 Affected file irssi/src/core/commands.c.
2130 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Added the server's public key sving and verification to the
2133 server when performing the SKE. This was missing and the
2134 remote server's (or router's) public key was accepted without
2135 checking whether we have it previously or trust it at all.
2136 Affected file silcd/protocol.c.
2138 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Check in the silc_server_timeout_remote if protocol is active
2141 and make sure that the protocol's final callback is called so
2142 that all memory if freed. Affected file silcd/server.c.
2144 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * silc_server_whois_send_reply crashed the server if the nickname
2147 was 127 characters long. Affected file silcd/command.c.
2149 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Added sanity check to the silc_server_new_client. If the hostname
2152 is provided inside username then check that the provided hostname
2153 really is the same as the resolved one. If the hostname was not
2154 resolved then check it from the public key. Affected file is
2155 silcd/packet_receive.c.
2157 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2158 if the server disconnected us and the connection is not valid
2159 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2161 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2162 the library to the lib/silcutil/silcutil.[ch].
2164 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Close log file after open. Affected file
2167 lib/silcutil/silclog.c.
2169 * Check whether sock == NULL in silc_client_send_packet and return
2170 if it is. Affected file lib/silcclient/silcclient.c.
2172 * Check rec->entry == NULL in the Irssi SILC Client before
2173 sending the channel message. Affecte file is
2174 irssi/src/silc/core/silc-servers.c.
2176 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Merged a splitted window bugfix from Irssi CVS tree. The
2179 affected file is irssi/src/fe-text/textbuffer-view.c.
2181 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2182 It did not print nickname.
2184 * Improved the distributions system a bit.
2186 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2189 irssi/src/fe-text/gui-window.c.
2191 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2192 to in-active server. The affected file is
2193 irssi/src/silc/core/client_ops.c.
2195 * Resolve the client in USERS command reply if the entry does
2196 not have username resolved. The affected file is
2197 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2198 command to WHOIS command to really resolve stuff. The USERS
2199 is not used any more in any critical section so WHOIS can
2200 be used even though it might be slower than IDENTIFY.
2202 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2205 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Changed the protocol API a bit more consistent in the
2208 lib/silccore/silcprotocol.[ch].
2210 * Changed the following headers to ROBODoc format:
2212 lib/silccore/silcpayload.h
2213 lib/silccore/silcprotocol.h
2214 lib/silccore/silcsockconn.h
2216 All core library headers are now formatted.
2218 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Fixed a bug in Irssi SILC client; do not show that you are
2221 server/router operator if you really are not. Affected file is
2222 irssi/src/silc/core/client_ops.c.
2224 * Renamed silc_command_free_payload to silc_command_payload_free.
2225 Affected file lib/silccore/silccommand.h
2227 * Added silcmath.h to include the prototoypes of various routines
2228 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2231 * Changed the following headers to ROBODoc format:
2233 lib/silccore/silcchannel.h
2234 lib/silccore/silccommand.h
2235 lib/silccore/silcid.h
2236 lib/silccore/silcidcache.h
2237 lib/silccore/silcmode.h
2238 lib/silccore/silcnotify.h
2239 lib/silccore/silcpacket.h
2240 lib/silcmath/silcmath.h
2242 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Added checking to the server code not to start the server if
2245 ciphers and stuff are not configured properly. Affected files
2246 silcd/serverconfig.[h] and silcd/server.c.
2248 * Changed the layout of the header files of the public interfaces
2249 in the SILC libraries. The new layout supports ROBODoc
2250 documentation tool (and some others) so that it is easy to create
2251 a library reference manual. All the other headers and source
2252 code must still follow the CodingStyle document. Also source
2253 code must not include these ROBODoc stuffs, only the headers.
2254 Furthermore, all public interface headers must now be named
2255 by using `silc' prefix, example: silcapi.h, silccipher.h.
2256 Some files were renamed due to this. All the other headers
2257 must not be used as public interfaces. I will update the
2258 CodingStyle document later. Changed following headers, so far:
2260 lib/silcclient/silcapi.h
2261 lib/silccore/silcauth.h
2262 lib/silccore/silcprivate.h
2263 lib/silccrypt/silcdh.h
2265 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Removed silc_client_packet_send_flush from the client library
2270 as it is not needed. Affected file lib/silcclient/client.[ch].
2272 * Added printing of message of unresolved authentication method
2273 to the Irssi SILC client. Added it to the module formats.
2274 Removed the same message from the client library.
2276 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Added new distribution feature, DISTLABEL. Every distribution
2279 can define own preprocessor label that can be used in the
2280 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2281 file distributions, acconfig.h.pre and prepare.
2283 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Added Makefile.defines_int to include the actual definitions
2286 for Makefile.defines.in. Tested the new distribution system,
2287 created distributions and tested installation.
2289 * Added AWAY message printing to the Irssi SILC client. Added
2290 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2292 * Added SCONNECT command to call the SILC's CONNECT command.
2293 Cannot use CONNECT directly since Irssi uses that internally.
2294 Affected file irssi/src/silc/core/silc-servers.c.
2296 Added ACTION local command. It is same as ME command but takes
2297 the channel as mandatory argument.
2299 Rewrote some of the Irssi's help files to suite for SILC
2302 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Added Makefile.defines[.in] that should for now on be included
2305 in all Makefile.am file in the source tree. That file includes
2306 all common compilation definitions for SILC source tree.
2308 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Minor changes to the ./prepare script to change the package
2311 name according the distribution name to the configure.in.
2313 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Created new distribution system. Added file `distributions'
2316 that defines all the distributions that can be created out of
2317 the SILC source tree. The ./prepare script now reads that
2318 file to determine how to prepare the distributions. The
2319 first argument to the ./prepare is the name of the distribution
2320 and second is the version of the distribution. If given
2321 without arguments it creates the default (toolkit) distribution
2322 with the default version (defined in ./prepare).
2324 All Makefile.am files that are subject to the distributions
2325 are now named as Makefile.am.pre. These are ./Makefile.am
2326 and lib/Makefile.am. Others may be changed later.
2328 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2330 * Added invite list, ban list, some key management and connection
2331 error message printing to module formats in the Irssi SILC client.
2333 * Added new silc_client_set_away_message to set the away message
2334 that is back to the person who sent private message. The
2335 affected file lib/silcclient/silcapi.h and the
2336 lib/silcclient/client_prvmsg.c.
2338 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Fixed the private message sending in the Irssi SILC client,
2341 added local command KEY to the Irssi SILC client.
2343 Added key management and key agreement message formats to the
2344 irssi/src/fe-common/silc/module-formats.[ch].
2346 Added USERS (alias WHO) printing, server/router operator
2347 indication and LIST command printing to the module formats.
2349 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Fixed channel joining notify handling, cumode notify handling
2352 from Irssi SILC client.
2354 * Added SILC specific module-formats to the Irssi SILC client so
2355 that SILC specific message hilighting, colors etc is possible.
2356 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2358 Added channel mode, channel user mode, actions, notices,
2359 whois and whowas printing to the the module-formats.c.
2361 * Fixed a bug in channel deletion in the server. The channel
2362 is not left to the cache even if the channel founder auth mode
2363 is set when there are no users anymore on the channel. Affected
2364 file silcd/server.c.
2366 * The silc_net_localhost now resolves the entire hostname including
2367 the domain name. Affected file lib/silcutil/silcnet.c.
2369 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Changed the ask_passphrase client operation to be ascynchronous.
2372 It has now a completion callback and a context that the
2373 application must call after it has got the passphrase from
2374 the user. Affected files lib/silcclient/silcapi.h,
2375 lib/silcclient/protocol.c, lib/silcclient/command.c and
2378 Added SilcAskPassphrase callback that the application calls
2379 to deliver the passphrase to the library.
2381 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2382 The public key verification and especially a certificate
2383 verification is asynchronous procedure.
2385 Added new SILC_SKE_STATUS_PENDING status to indicate the
2386 request is pending and a callback will be called to finalize
2389 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2390 indicate that remote end did not send its public key (or
2391 certificate), even though we require it. Added check for this
2392 condition in the SKE. This was a security bug, now fixed.
2394 Defined new SilcSKEVerifyCbCompletion callback that is called
2395 when the verification process is completed.
2397 The affected files lib/silcske/silcske_status.h and
2398 lib/silcske/silcske.[ch].
2400 * Changed the verify_public_key client operation to be async
2401 as well. Defined SilcVerifyPublicKey callback that is used to
2402 indicate the success of the public key verification process.
2404 Changed the server and client to use the new async client
2407 * Changed the Irssi SILC client's internal scheduler to be called
2408 twice as many times as it used to be. As a result the client
2409 should be a bit faster now. Affected file is
2410 irssi/src/silc/core/silc-core.c.
2412 * Added support to Irssi SILC client of asynchronous public key
2413 verification and passphrase inquiry. Affected file is
2414 irssi/src/silc/core/silc-core.c.
2416 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Do not say "You have left channel %s" in client library.
2419 Moved it to the application. Affected files are
2420 lib/silcclient/command.c and silc/client_ops.c.
2422 * Fixed silc_client_get_clients. Command context was not
2423 duplicated and was freed memory in the callback. Affected
2424 file lib/silcclient/idlist.c.
2426 * Do not say "you are now talking..." on JOIN command in the
2427 client library. The appliation must handle it.
2429 * Do not say ".. changed topic to" in command reply in the
2430 client libary. The application must handle it.
2432 * Fixed TOPIC command sending in the client library.
2434 * Fixed a memory leak in silc_client_command_free in the file
2435 lib/silcclient/command.c.
2437 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Imported a modified version of Irssi client to the source tree.
2440 The Irssi will be used to create a new client called
2441 Irssi SILC. Imported to irssi/.
2443 Added silc_core_init_finish function to the Irssi. Affected
2444 file irssi/configure.in.
2446 A lot changes in the Makefile.ams around the irssi tree.
2448 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2450 * Do not rehash if the new size is same as the old size of the
2451 hash table, in the silc_hash_table_rehash*. The affected file
2452 lib/silcutil/silchashtable.c.
2454 * Replaced hash_table_del_by_context calls from the server
2455 (when channel->user_list and client->channels) to the
2456 hash_table_del as it is sufficient and faster.
2458 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Added silc_hash_table_list, silc_hash_table_get and the
2461 SilcHashTableList structure to provide an alternative way to
2462 traverse the hash table. The affected files are
2463 lib/silcutil/silchashtable.[ch].
2465 * Changed the server's idlist routines to use the hash table
2466 routines to optimize the code.
2468 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Replaced the client entry's `channel' list and channel entry's
2471 `user_list' list to hash tables for optimized lookup. Changed
2472 the code to use the hash table interface around the code.
2473 Affected file lib/silcd/idlist.[ch].
2475 * Added `auto_rehash' boolean argument to the function
2476 silc_hash_table_alloc to indicate whether the hash table should
2477 auto-rehash when it thinks is appropriate time. It will
2478 increase the hash table size if the there is twice as much
2479 entries in the table than the size of the table, and will
2480 decrease the size if there are twice as less entries than
2481 the size of the table.
2483 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2487 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * silc_idcache_purge_by_context deletes the entry now by context
2490 as it is supposed to do. Affected file lib/silccore/idcache.c.
2492 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2493 client is not anymore valid (WHOWAS givens the info) and not
2494 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2496 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Removed the `data' and `data_len' arguments from the ID Cache
2499 interfaces and added `name' argument. ID Cache does not handle
2500 anymore the binary data only a names associated with given ID.
2502 * When hashing a Client ID with silc_hash_id the entire ID is
2503 not hashed anymore, instead only the hash of the Client ID is
2504 hashed. This way we can access the Client ID from the cache
2505 with Client ID but with the hash of the ID (which is a hash of
2506 the nickname) as well without any difference in performance.
2508 Added also silc_idcache_find_by_id_one_ext to do one on one
2509 searching when we have the actual ID. Added also function
2510 silc_hash_client_id_compare. The affected files are
2511 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2513 * When hashing the name associated with a ID it is always done
2514 in lowercase. This way we can access the cache without worrying
2515 about case-sensitivity, even though, for example nicknames are
2518 * Fixed a bug in server with channel message sending. It put
2519 wrong ID type as destination ID. The affected file
2520 silcd/packet_send.c.
2522 * silc_idcache_del_by_context now deletes from all hash tables
2523 by context. Affected file lib/silccore/idcache.c.
2525 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Changed the client library to use the new ID Cache interface.
2528 Changes around the source tree.
2530 * Added silc_hash_table_rehash_ext to rehash with specific
2531 hash function. Affected file lib/silcutil/silchashtable.[ch].
2533 * Added silc_hash_string_compare to compare two strings in the
2534 hash table. Affected file lib/silcutil/silcutil.[ch].
2536 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Added new function silc_idcache_del_by_context into the
2539 lib/silccore/idcache.[ch].
2541 * Changed the server's ID list routines to use the new ID Cache
2542 interface. Changes around the source tree.
2544 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Added silc_hash_table_del[_by_context]_ext functions in to the
2547 lib/silcutil/silchashtable.[ch].
2549 Removed silc_hash_table_find_all* routines and added new
2550 silc_hash_table_find_foreach to replace them.
2552 Added silc_hash_table_replace_ext function as extended
2553 replacing function. Separated the simple hash table interface
2554 from the extended hash table interface in the file
2555 lib/silcutil/silchashtable.h.
2557 * Fixed minor bugs and changed it to use some of the new
2558 hash table functions in lib/silccore/idcache.c
2560 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Added new function silc_hash_table_find_all to return all keys
2563 in the hash table by the specified key. As the hash table is
2564 collision resistant it also makes it possible to have several
2565 duplicate keys in the hash table. This function may be used to
2566 find all of the keys from the hash.
2568 Added user_context arguments to the SilcHashFunction,
2569 SilcHashCompare and SilcHashDestructor to deliver user specified
2572 Added new fuctions silc_hash_table_find[_all]_ext to do
2573 extended lookup with specified hash and compare functions and
2574 specified user contexts.
2576 Added new function silc_hash_table_add_ext to add the key
2577 with specified hash function and user context.
2579 Added new function silc_hash_table_foreach to traverse all
2580 entrys in the hash table. Added SilcHashForeach callback
2583 Added new function silc_hash_table_del_by_context to delete
2584 the entry only if the context associated with the key matches.
2586 Affected files are lib/silcutil/silchashtable.[ch].
2588 * Removed silc_hash_[server/client/channel]_id and added just
2589 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2590 silc_hash_id_compare to compare two ID's using as the hash table
2591 comparison function. Added also silc_hash_data to hash
2592 binary data and silc_hash_data_compare to compare it.
2594 * Removed silc_idlist_find_client_by_hash as it is not needed
2595 anymore. Affected file silcd/idlist.[ch].
2597 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2598 to use internally the SilcHashTable. The new ID Cache is a lot
2599 faster than the old one. Some of the ID Cache interface was also
2600 rewritten and obsolete and stupid functions were removed.
2602 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Added entry_count field to the SilcHashTable to keep the number
2605 of the entries in the table. Implemented the function
2606 silc_hash_table_rehash. Added new function
2607 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2609 Fixed a minor bug in silc_hash_table_free.
2611 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2612 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2613 into the lib/silcutil/silcutil.[ch].
2615 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Implemented a collision resistant hash table into the
2618 lib/silcutil/silchashtable[ch]. See the header and the source
2619 for the SilcHashTable API.
2621 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Merged dotconf version 1.0.2 into lib/dotconf.
2625 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Do not compile anything in lib/silcsim/* if the SIM support
2628 is not enabled. The tree should now compile without problems
2631 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Compiled the SILC under cygwin. Compiled and tested briefly
2634 without problems. More tests needed. The SIMs didn't compile
2637 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2639 * Fixed possible crash in silc_get_username in the
2640 lib/silcutil/silcutil.c.
2642 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Fixed a va_arg in silc/client_ops.c.
2646 * Oops, RC5 routines were named AES and caused some problems
2647 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2649 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Added new SilcIDIP structure into the lib/silccore/id.h and
2652 replaced the old `ip' fields from all SILC ID's to that type.
2653 This is a step towards IPv6 support.
2655 The silc_id_get_len takes now the ID as an extra argument.
2656 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2657 both IPv4 and IPv6 based ID's.
2659 The affected files are lib/silccore/id.[ch] and other files
2660 around the tree using these routines.
2662 * Removed the ID length arguments in server from various
2663 silc_server_send_notify_* routines -> they are not needed
2666 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Fixed memory leak in silc_encode_pem_file in the file
2669 lib/silcutil/silcutil.c.
2671 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Check minor version as well in the SKE. Affected files are
2674 silcd/protocol.c and lib/silcclient/protocol.c.
2676 * Added --identifier option to the server so that an identifier
2677 can be when creating the public key for the server. Affected
2678 file is silcd/silcd.c.
2680 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2681 lib/silccrypt/silcpkcs.c.
2683 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Register default ciphers and stuff when using -C option with
2686 the server. Affected file sildc/silcd.c.
2688 * Put back the servers public key filename format, it is better
2689 than the new one. For now, the client keys are saved with the
2690 new filename format. The affected file silc/client_ops.c.
2692 * Implemented the Cipher API for the rest of the ciphers that
2693 did not implement it or implemented it the wrong way.
2695 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Register default ciphers and stuff when using the -S option
2698 in the client. Affected file silc/silc.c. Same also when
2699 creating new key pair with -C option.
2701 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Fixed the silc_verify_public_key client operation function to
2704 save the public keys differently. The fingerprint is now
2705 used as filename and not the hostname. This way also the
2706 client keys are saved uniquely and not with hostnames. The
2707 affected file is silc/client_ops.c.
2709 * Trimmed the silc_hash_fingerprint function to remove extra
2710 whitespaces from the end of the fingerprint. The affected
2711 file is lib/silccrypt/silchash.c.
2715 * Added silc_cipher_register_default function to register all
2716 default ciphers. It can be used when configuration files
2717 does not exist and the application does not want any specific
2718 ciphers in any specific order.
2720 The SilcDList is now used as silc_cipher_list dynamically
2721 allocated cipher list. Removed the static list all together
2722 and now all ciphers must be allocated to the dynamic list.
2723 The silc_cipher_alloc routine was changed to check only the
2726 All silc_cipher_* routines that used to return int returns
2729 The affected files lib/silccrypt/silccrypt.[ch].
2731 * The same thing was done to silc_hash_* as for silc_cipher_*
2732 routines. Affected files lib/silccrypt/silchash.[ch].
2734 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2735 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2736 Added also silc_pkcs_[un]register[_default] functions.
2737 Removed the data_context from the PKCS API.
2739 * Added silc_hmac_register_default function to register default
2740 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2741 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2742 to unregister all hmacs at once.
2744 * Register the default ciphers, hash functions, PKCSs and HMACs
2745 if client's configuration file does not exist. The affected
2748 * The client did not load the hash functions from the SIM
2749 modules at all. Added support for this. Affected file is
2750 silc/clientconfig.c.
2752 * When decoding public key with silc_pkcs_public_key_decode, check
2753 the supported algorithm only if PKCS are registered. Affected
2754 file lib/silccrypt/silcpkcs.c. The same was done with the
2755 silc_pkcs_private_key_decode.
2757 * Fixed the SILC List routines to keep the list always in order.
2758 It used to change the list's order when traversing the list but
2759 not it preserves the order. Affected file lib/trq/silclist.h.
2761 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Added the client library to use the SilcSocketConnection's
2764 reference counter (by silc_socket_dup) to prevent the bug that
2765 the socket object may be freed underneath async operation.
2767 * The name resolv library checking fixes in the configure.in.pre.
2770 * Created new version of the protocol drafts for future
2771 development. The -03 drafts are the ones that will be changed
2772 in the trunk now and the -02 will remain as they are.
2774 * Send list of CUMODE notifys to the router when announcing
2775 the channel users to the router. Affected file silcd/server.c.
2776 If the router receiving channel founder CUMODE for a channel
2777 that already has channel founder it will send CUMODE notify
2778 to the sender to remove the channel founder rights from the
2779 announced client. Affected file silcd/packet_receive.c.
2781 * The CUMODE notify may now use Server ID as well as the entity
2782 who changes the mode. Updated protocool specs.
2784 * Updated INSTALL and README files.
2786 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * New web pages in the http://silc.pspt.fi. The pages was
2793 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Implemented the [DenyConnectin] config section in the server.
2796 Added silc_server_config_denied_conn to check whether incoming
2797 connection is denied. Affected file silcd/serverconfig.[ch].
2799 * Do not check the ports when checking the incoming configuration
2800 data if the port is 0, meaning any. Affected file is
2801 silcd/serverconfig.c.
2803 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Fixed buffer overflow in silc_string_compare in the file
2806 lib/silcutil/silcutil.c.
2808 * Fixed double free in silc_server_command_leave in the file
2811 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Fixed the version checking in the server. Affected file is
2816 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Fixed the configuration data fetching when accepting new
2819 connections in the server. Affected file silcd/server.c.
2821 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Added `sender_entry' argument to the function
2824 silc_server_packet_relay_to_channel so that we can check
2825 whether some destination actually belongs to the same route
2826 the sender belongs (ie, we must not resend the packet to the
2827 sender). Affected file silcd/packet_send.[ch].
2829 * Added `servername' field to the SilcClientEntry in the server
2830 to hold the name of the server where client is from. Affected
2831 file is silcd/idlist.h.
2833 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Moved the channel message encrypting in the router betwen
2836 router connections from silc_server_channel_message to the
2837 silc_server_packet_relay_to_channel since we want to check
2838 whether we have anybody channel before encrypting anything.
2839 Affected files silcd/packet_[receive/send].c.
2841 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Fixed the [AdminConnection] server config section to support
2844 multiple entries. Affected file silcd/serverconfig.c.
2846 * Added support into the server to check the validity of the
2847 incoming connection before executing any KE or authentication
2850 * The connection configuration is now saved to the KE and
2851 connection auth protocol contexts and not fetched anymore in
2852 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2854 * The local hosts listenning address and port is also resolved
2855 now when starting the server. We want to have the socket object
2856 to include the real address and port for the listener. Added
2857 new function silc_net_check_local_by_sock into the files
2858 lib/silcutil/silcnet.[ch].
2860 * Fixed a broadcast bug in server -> do not broadcast if we
2863 * Fixed a routing bug. Do not route broadcast packets ever.
2864 Broadcast packets must be processed always and not routed since
2865 they may be destined to some other host than yourself and thus
2866 would get routed without no good reason. Affected file is
2869 * Added function silc_server_config_is_primary_route to check
2870 whether primary router connection has been configured (a router
2871 configuration that we are initiating). If there is not, we
2872 will assume that there is only two routers in the SILC network
2873 and we will use the incoming router connection as our primary
2874 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2876 * Changed the order of the broadcasting. Broadcast _after_ the
2877 packet has been processed not before. Affected file is
2880 * Fixed a [ClientConnection] parsing bug. The port was never
2881 parsed correctly thus resulting to port 0. Affected file
2882 silcd/serverconfig.c.
2884 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2885 argument and did not set the broadcast packet flag. Affected
2886 file silcd/packet_send.c. Fixed same bug in the function
2887 silc_server_send_notify as well.
2889 * If we receive NEW_ID packet for our own ID in the server, ignore
2892 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Removed the nickname from the Private Message Payload.
2897 Updated the code and the protocol specs.
2899 * Updated protocol specs for submitting to the IETF.
2901 * Tweaked the Random Number Generator a bit. Affected file
2902 lib/silccrypt/silcrng.c. Exported a new function
2903 silc_rng_[global]_add_noise which can be used to add more
2906 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Do not parse packets with different timeout when protocol
2909 is active -> may cause problem with rekey. Affected file
2912 * When server receives signoff notify it must not create
2913 new channel key if the client is on any channels since the
2914 sender of the signoff notify will create it.
2916 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2918 * Added printing of error messages during SKE protocol from the
2919 failure packet sent by server during SKE. Affected file
2922 * Removed the client's failure_callback handling with timeout
2923 and handle it immediately when received.
2925 * The SKE library returned wrong type in SUCCESS and FAILURE
2926 packets. They must be 32 bit MSB not 16 bit MSB.
2928 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Ok, rewrote the logic of the re-key and now it seems to work.
2931 I tested it on high traffic with frequent re-keys without
2932 problems. Added hmac_receive (and renamed hmac to hmac_send)
2933 in SilcClientConnection in lib/silcclient/client.h and
2934 in SilcIDListData in silcd/idlist.h. Also, removed the
2935 SilcPacketParserContext's cipher and hmac fields as they are
2936 not needed anymore and actually caused some problems when
2937 the ciphers and hmac's changed underneath the packet parser.
2939 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * If re-key protocol is active then process the incoming packets
2942 synchronously since we must assure that icoming packets encrypted
2943 with the old key is processed before the new keys is set to
2944 use. This is true other packets than for REKEY packets.
2945 Affected file silcd/server.c. The same was done to client library
2946 as well, affected file lib/silcclient/client.c.
2948 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Fixed bug in client and server to accept the force send if
2951 the packet is send from silc_[server/client]_packet_process
2952 function. Otherwise the packets are never delivered, oops.
2954 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Disable force sending of packets when REKEY protocol is active.
2957 We must assure that no packet is sent directly when rekey is
2958 performed. All packets must be sent through packet queue.
2959 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2960 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2961 function is silc_[server/client]_packet_send_real to check
2964 * Replaced the SIM paths from example config files to
2965 /usr/local/modules. Also, make install creates now
2966 /usr/local/silc/logs directory to hold all the SILC server
2969 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Made the configure.in.pre work on Solaris. Patch by salo.
2973 * Made all ciphers compatible with non-x86 machines. Defined
2974 CBC mode macros into lib/silccrypt/ciphers_def.h.
2976 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Fixed the make install.
2980 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * When MAC computation fails the silc_packet_decrypt returned 0
2983 even though it was supposed to return -1. Fixed this. The
2984 affected file is lib/silccore/silcpacket.c.
2986 * Do not replace the config files in /etc/silc (in make install)
2987 if they already exist. Affected file ./Makefile.am.
2989 * Do not send re-key packets immediately but through packet queue.
2990 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2992 * Changed silc_net_check_host_by_sock to return FALSE if the
2993 IP/DNS could not be resolved. Though, it returns the IP address
2994 now even if it could not resolve it (but returns also FALSE).
2995 Affected file lib/silcutil/silcnet.[ch].
2997 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Added silc_pkcs_decode_identifier to decode the public key's
3000 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3001 Added also silc_pkcs_free_identifier. Added also new context
3002 SilcPublicKeyIdentifier.
3004 * Added -S option to the silc client. It is used to dump the
3005 contents of the specified public key file.
3007 * Changed the PKCS api to return the public key length when
3008 setting the public key.
3010 * Fixed a fatal bug in the public and private key file loading.
3011 Affected file lib/silccrypt/silcpkcs.c.
3013 * Execute the packet parsing for client with zero (0) timeout
3014 if the protocol is active. Affected file silcd/server.c.
3016 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Made the key generation options to the silcd program. Added
3019 -C option, equivalent to client's option.
3021 * Added new [ServerKeys] config section to the server. It
3022 configures the server's public and private key.
3024 * Defined generic Public Key Payload into the protocol
3025 specification to send specific type of public keys and
3028 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3029 public key or certificate.
3031 * Implemented the GETKEY command to the server and to the
3032 client library and on user interface.
3034 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Made preliminary `make install' work.
3038 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Added SilcServerRekey context into silcd/idlist.h.
3042 * Added the PFS support as defined in the specification to the
3043 SKE protocol. Affected files lib/silcske/*.c.
3045 * Added `ske_group' field to the SilcServerRekey context to hold
3046 the number of the SKE group that is used with PFS in re-key.
3047 Affected file silcd/idlist.h.
3049 * Added PFS re-key support to the server. Affected file is
3052 * Added silc_protocol_cancel to cancel execution of the next
3053 state of the protocol. Affected file is
3054 lib/silccore/silcprotocol.[ch].
3056 * Added the re-key support with and without PFS to the client
3057 library. Re-key is performed once in an hour, by default.
3059 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3060 Added silc_client_rekey_callback and silc_client_rekey_final.
3061 Affected files are lib/silcclient/protocol.[ch] and
3062 lib/silcclient/client.[ch].
3064 * Removed the `hmac_key' and `hmac_key_len' fields from the
3065 SilcClientConnection structure; not needed. Affected file is
3066 lib/silcclient/client.h.
3070 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Do not ask whether user wants to use the negotiated private key
3073 for private messages, just use it. Affected file is
3074 silc/local_command.c.
3076 * Added `send_enc_key' and `enc_key_len' fields to the
3077 SilcIDListData structure since they are needed in the re-key
3078 phase. Affected file is silcd/idlist.[ch].
3080 * Implemented the simple re-key protocol into the server.
3081 Affected files silcd/server.c and silcd/protocol.[ch]. The
3082 re-key will be performed once in an hour, by default.
3084 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3085 Added silc_server_rekey, silc_server_rekey_callback and
3086 silc_server_rekey_final.
3088 * Removed Tunneled flag from the protocol. Updated the code
3089 and the specifications.
3091 * Adde `pfs' field to the SilcIDListData to indicate whether
3092 the PFS is to be performed in the re-key. Affected file is
3095 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3098 int64 of at least the xintXX size. If void * is less that 4
3099 bytes uint32 * will be used. Defined bool as boolean.
3101 * Changed _ALL_ unsigned long and unsigned int to uint32,
3102 unsgined short to uint16 in the source tree.
3104 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3105 not handle clients that has entry->data.registered == FALSE.
3106 They are not in the network anymore. Affected file is
3109 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Implemented the sending of the SERVER_SIGNOFF notify in the
3112 server. Affected file is silcd/server.c.
3114 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3115 Added also silc_notify_payload_encode_args into the
3116 lib/silccore/silcnotify.[ch].
3118 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3119 Affected file silcd/packet_receive.c.
3121 * Implemented the SERVER_SIGNOFF notify handling in the client
3122 library. Affected file lib/silcclient/client_notify.c. Also,
3123 implemnted the printing of the SERVER_SIGNOFF info to the
3124 application. Affected file silc/client_ops.c.
3126 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3127 if the deleting was successful. Affected file silcd/idlist.[ch].
3129 * Added support for public key authentication in the connection
3130 authentication protocol in the client library. Affected file
3131 lib/silcclient/protocol.c.
3133 * Changed the server's silc_idlist_get_clients_by_* interface
3134 to support already allocated array so that new entries may be
3135 added to pre-allocated array. Affected file silcd/idlist.[ch].
3136 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3137 and command replies.
3139 * All command reply functions in the server now calls the
3140 pending command callback even if error occured. This way the
3141 error will be delivered to the client as well. Affected files
3142 silcd/command.c and silcd/command_reply.c.
3144 * Fixed INFO command to return local server's info if no server
3145 was provided. Affected file lib/silcclient/command.c.
3147 * Removed RESTART command for good. Updated the code and the
3150 * Rewrote parts of the task system. It is a bit simpler now.
3151 Removed unsued task priorities. The affected files are
3152 lib/silcutil/silctask.[ch].
3154 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Moved the USERS printing from the library to the application.
3157 Affected files lib/silcclient/command.c and silc/client_ops.c.
3159 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Added channel key re-key support. The re-key is perfomed
3164 only by the router and is done once in an hour. Added `rekey'
3165 field to the SilcChannelEntry in the server. Affected files
3166 silcd/server.c and silcd/idlist.h.
3168 * Added silc_task_unregister_by_context into the file
3169 lib/silcutil/silctask.[ch].
3171 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * Added SILC_UMODE_GONE mode to indicate when the client is not
3174 present in the SILC network. Added also support to the local
3175 command AWAY that will set this mode. Added support of showing
3176 "xxx is gone" in WHOIS command. The USERS command shows the
3177 gone status as well.
3179 * Fixed setting server and router operator privileges in the
3180 server's UMODE command. Affected file silcd/command.c.
3182 * Merged the SKE KE1 and KE2 payloads into one payload. The
3183 new KE payload is equivalent to the old KE2 payload.
3185 Cleaned up the SKE Start Payload parsing. It now uses the
3186 simple buffer unformatting to do the parsing. A lot faster
3189 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3190 to the SKE that is used to indicate whether both of the SKE
3191 parties should perform authentication. By default only the
3192 responder performs authentication. By setting this flag also
3193 the initiator must do authentication. By default it is unset
3194 since in normal SKE case, client to server connection, only
3195 the responder should do authentication. When doing SKE between
3196 two clients both should perform authentication. Updated the
3197 code and the protocol specs.
3199 * A little fix to IDENTIFY command in the server. Search the
3200 client first by hash not nickname. Affected file is
3203 * Fixed the silc_client_close_connection to support closing
3204 the client to client connections wihtout deleting too much
3205 data. Affected file lib/silcclient/client.c.
3207 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3208 are received if protocol used to be active but is not anymore
3209 the application would crash due to NULL pointer dereference.
3210 Affected files silcd/server.c and lib/silcclient/client.c.
3212 * Added `hash' field to the SilcClientConnection to include
3213 the hash function negotiated in the SKE protocol.
3215 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3216 to set the channel founder authentication data. A client can
3217 claim the founder rights later by providing the authentication
3218 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3219 This way the channel founder can regain the channel founder
3220 privileges even it is left the channel. This works only on
3221 local server and the client must be connected to the same
3222 server to be able to regain the founder rights. Updated the
3223 protocol specs accordingly.
3225 Added support to the CMODE command in the client to set the
3226 founder auth data. Read the README to see how to set it.
3228 Added support to the CUMODE command to claim the founder
3229 rights. Read the README to see how to do it.
3231 Added support for the founder authentication to the Channel
3232 Entry in the server. Affected file silcd/idlist.h.
3234 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3235 server's CMODE command. Affected file silcd/command.c.
3237 * Added the following new functions into lib/silccore/silcauth.[ch]:
3238 silc_auth_get_method and silc_auth_get_data.
3240 * The server now saves the remote hosts public key to the
3241 SilcIDListData pointer. Affected file silcd/protocol.c.
3243 * The normal server now does not remove the channel entry from
3244 the cache if the founder authentication data is set. It used
3245 to remove it if the founder was the last one on the channel on
3246 the server and left the channel. The auth data is saved and
3247 if the channel is re-joined later the old entry is used with
3248 the old auth data. Affected files silcd/command_reply.c and
3251 * Removed the `pkcs' field from the SilcIDListData structure
3252 in the server; it is not used. Affected file silcd/idlist.h.
3254 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Fixed packet processing on slow links. Partial packets were
3257 never re-processed because the incoming data buffer was cleared
3258 by the application. Application must not directly clear the
3259 sock->inbuf, the packet processing routines handle it. Fixed
3260 this in client library and in server.
3262 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Fixed the WHOIS and IDENTIFY send reply function to really
3265 check whether to send list or just one entry. Affected file
3268 * Cleaned up the LEAVE command's channel key distribution. The
3269 affected file silcd/command.c.
3271 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3272 can enforce the channel mode as well. In that case the ID
3273 includes the ID of the server. The code now enforces the
3274 mode change if the router have different mode than the server.
3276 * The notify client operation with CMODE_CHANGE notify can now
3277 return NULL client_entry pointer if the CMODE was not changed
3278 by client. Application must check for this.
3280 * Added <Server ID> argument to INFO command to support server
3281 info fetching by Server ID.
3283 * Added silc_server_announce_get_channel_users to get assembled
3284 packets of channel users of the specified channel. Affected
3285 file silcd/server.[ch].
3287 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3288 was freed underneath the ID Cache.
3290 * Re-announce clients when the server received CHANNEL_CHANGE
3291 notify from the router. Affected file silcd/packet_send.c.
3293 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3296 crashed since it did not handle the fact that there is no cipher
3297 called "3" and didn't check the error condition. Now fixed.
3299 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3300 flag. It can be used to send message requests.
3302 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Implemented the RESTART command in the client.
3306 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3307 notice type messages. Added notice printing to the user
3310 * The channel keys are not re-generated if the channel's mode
3311 is PRIVKEY, ie private key on the channel exists. Affected
3312 files silcd/server.c and silcd/command.c.
3314 * Fixed a little bug in channel message delivery when channel
3315 private keys are set in the server. Affected file is
3316 silcd/packet_send.c.
3318 * Changed the setting on channel->on_channel = TRUE from the
3319 silc_client_save_channel_key to the JOIN command reply. The
3320 key payload is not received if the private channel key is set.
3321 Affected file lib/silcclient/command_reply.c and the
3322 lib/silcclient/client_channel.c.
3324 * When the CMODE_CHANGE notify is sent and the channel private
3325 key mode is removed the channel key must be re-generated in
3326 other cells as well. Added this support for the router in the
3327 silcd/packet_receive.c.
3329 * Added new local command NOTICE to send notice message on
3330 channel. Affected file silc/local_command.[ch].
3332 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Added new local command ME to the client. It is used to send
3335 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3336 some action. Affected file silc/local_command.[ch].
3338 * Changed channel_message and private_message client operations
3339 to deliver the message flags to the application. Added also
3340 the `flags' arguments to the silc_client_send_channel_message
3341 and silc_client_send_private_message functions. Affected file
3344 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Redefined the Private Message Payload to support private message
3347 keys and to support the new private message flags. Updated
3348 the protocol specs. Flags makes it possible to have for example
3349 CTCP style messages.
3351 * Added new type SilcPrivateMessagePayload and defined an API
3352 for it in the lib/silcclient/silcprivate.[ch].
3354 * Tested private message private keys successfully. Tested the
3355 private message key set, unset and list commands with the new
3358 * Redefined the Channel Message Payload to include the channel
3359 message flags (equal with private message flags) to support
3360 for example CTCP style messages.
3362 * Defined some of the message (for channel and private message)
3363 flags. Updated the protocol specs and added the flags to the
3364 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3366 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Added SilcKeyAgreementStatus type to the key agreement routines
3369 to indicate the current status and error if one occured.
3370 The status types are defined in the lib/silcclient/silcapi.h.
3372 * Added new local command KEY that is used to set and unset private
3373 keys for channels, set and unset private keys for private messages
3374 with remote clients and to send key agreement requests and
3375 negotiate the key agreement protocol with remote client. The
3376 key agreement is supported only to negotiate private message keys,
3377 it currently cannot be used to negotiate private keys for channels,
3378 as it is not convenient for that purpose.
3380 * Fixed a minor pending callback setting bug in the function
3381 silc_client_get_client_by_id_resolve, now the function works.
3382 Affected file lib/silcclient/idlist.c.
3384 * Added function silc_net_get_local_port to get local bound
3385 port by socket. Added to lib/silcutil/silcnet.[ch].
3387 * Added `sockets' and `sockets_count' fields to the SilcClient
3388 object. They hold the sockets of the listenning sockets in
3389 the client. Listenning sockets may be for example the key
3390 agreement server. Affected file lib/silcclient/client.[ch].
3391 Added functions the silc_client_add_socket and the
3392 silc_client_del_socket. They are exported to the application
3395 * Added ~./silc/clientkeys to support other client's public keys.
3397 * Renamed verify_server_key client operation to verify_public_key
3398 and added one argument to indicate the type of the connection
3399 (server, client etc.).
3401 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Added silc_server_connection_auth_request to handle the
3404 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3405 silcd/packet_receive.[ch].
3407 * Added silc_server_send_connection_auth_request into the
3408 silcd/packet_send.c to send the connection auth request packet.
3410 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3413 * Fixed the public key authentication in responder side in the
3414 server. The `auth_data' pointer includes the SilcPublicKey
3415 not the path to the public key. Affected file silcd/protocol.c.
3417 * Implemented the public key authentication in the initiator side
3418 in the server. Affected file silcd/protocol.c.
3420 * Removed the [RedirectClient] config section from the server
3421 configuration. Is not needed and I don't want to implement it.
3423 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Cleaned up the CMODE command in the server. It now works
3426 correctly and supports all the modes defined in the protocol.
3427 Affected file is silcd/command.c.
3429 * Added `hmac_name' field to the SilcChannelEntry in the server
3430 to hold the default HMAC of the channel. It can be set when
3431 creating the channel (with JOIN command). Affected files
3434 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3435 type to indicate the change of the current cipher and hmac
3436 on the channel. Client can safely ignore the <cipher> argument
3437 (if it chooses to do so) since the CHANNEL_KEY packet will
3438 force the channel key change anyway. The <hmac> argument is
3439 important since the client is responsible of setting the new
3440 HMAC and the hmac key into use.
3442 * Fixed the CMODE command in the client library as well.
3444 * Tested CMODE command in router environment successfully.
3446 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Show the version of the remote client (or server) when connecting
3449 to the server. It is logged to the log file. Affected file
3450 is silcd/protocol.c.
3452 * Fixed the KILLED notify handling in the client library. The
3453 client must be removed from all channels when receiving the
3456 Also, do not remove the client entry when giving the KILL
3457 command but when the KILLED notify is received.
3459 * Removed silc_idlist_find_client_by_nickname from the server.
3460 Not needed anymore. Affected files silcd/idlist.[ch].
3462 * Implemented the CHANNEL_CHANGE notify type handling to the
3463 server. Affected file silcd/server.c.
3467 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Added silc_server_send_notify_invite to send the INVITE
3470 notify between routers.
3472 * Implemented the INVITE command correctly to the server.
3474 * Implemented the INVITE notify type handling in the server.
3476 * Implemented the INVITE command to the client library and on the
3479 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Added function silc_server_get_client_resolve to find the
3482 client entry by ID from all ID lists and then resolve it
3483 (using WHOIS) if it cannot be found. Affected file is
3486 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Implemented the BAN command to the client library.
3490 * The JOIN command in the server now checks the invite list
3493 * Changed the silc_command_reply_payload_encode_va and the
3494 silc_command_payload_encode_va to support that if argument is
3495 NULL it ignores and checks the next argument. Affected file
3496 lib/silccore/silccommand.c.
3498 * Added silc_server_send_notify_ban to send the BAN notify
3499 type between routers.
3501 * Chaned the silc_notify_payload_encode to support that if
3502 argument is NULL it ignores and checks the next argument.
3503 Affected file lib/silccore/silcnotify.c.
3505 * Tested ban lists in router environment successfully.
3507 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3509 * Implemented BAN command to the server, in silcd/command.[ch].
3511 * Removed the BAN and INVITE_LIST modes from the CMODE command
3514 * Added function silc_string_match to regex match two strings.
3515 Affected files lib/silcutil/silcutil.[ch].
3517 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Redefined parts of the SilcChannelEntry in the server to support
3520 the new ban and invite lists.
3522 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Redefined the INVITE command. The same command can be used to
3525 invite individuals to the channel but also to manage the invite
3526 list of the channel (to add to and remove from the invite list).
3527 Updated the protocol specs.
3529 * Added new command SILC_COMMAND_BAN that can be used to manage
3530 the ban list of the channel. Updated the protocol specs.
3532 * Removed the channel modes: the SILC_CMODE_BAN and the
3533 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3534 in the CMODE command. The equivalent features are now available
3535 using INVITE and BAN commands. Updated the protocol specs.
3537 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3538 in the network about change in the current ban list. The notify
3539 type is not used by the client.
3541 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3542 support the invite lists.
3544 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Added new function silc_string_regexify that converts string
3547 including wildcard characters into regex string that can
3548 be used by the GNU regex library. Added into the file
3549 lib/silcutil/silcutil.[ch].
3551 Added silc_string_regex_combine to combine to regex strings
3552 into one so that they can be used as one regex string by
3553 the GNU regex library. Added into the file
3554 lib/silcutil/silcutil.[ch].
3556 Added silc_string_regex_match to match two strings. It returns
3557 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3559 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Imported GNU regex to the soruce tree into lib/contrib.
3562 Fixed some compiler warning from the regex.c.
3564 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Fixed MOTD command in the server to work in router environment.
3568 * Fixed the MOTD command in the client library to support
3569 the server argument in the command.
3571 * Added `nickname_len' argument to the silc_idlist_add_client
3572 in the server, as the `nickname' argument may be binary data
3575 * Added silc_idlist_get_channels to return all channels from
3578 * Implemented LIST command to the server. Affected file is
3581 * Implemented the LIST command to the client library and on the
3584 * Added [<user count>] argument to the LIST command reply.
3585 With private channels the user count is not shown.
3587 * Updated TODO and README.
3589 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * The client entry's data.registered must be TRUE even with
3592 global client entry on global client list. The data.registered
3593 is used to check whether the client is anymore in the network,
3594 for example with WHOWAS command so it must be valid.
3596 * Fixed the WHOWAS command in the server. It now actually works
3597 in router environment. Added function into silcd/command_reply.c
3598 silc_server_command_reply_whowas_save.
3600 * Added silc_idlist_purge function to the silcd/idlist.c
3601 to periodically purge the ID Cache.
3603 * Fixed INFO command in the server. It works now in router
3604 environment. Added <server name> argument to the INFO command
3605 reply. Updated the protocol specs.
3607 * Fixed minor bug in silc_idcache_purge to not purge if the
3608 expire value is zero.
3610 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3611 they were buggy because of the WHOWAS information.
3613 * Fixed local command MSG to handle the async resolving of
3614 the remote client properly. It used to fail the first MSG.
3615 Affected file silc/local_command.c.
3617 * Added `data_len' field to SilcIDCache context.
3619 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Update TODO. Todo in commands in the server.
3623 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3626 used by routers as broadcast packet to inform other routers
3627 about the changed user mode.
3629 Implemented the notify handling in the server. Affected file is
3630 silcd/packet_receive.c. Added the function
3631 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3633 * Added new generic Channel Payload and deprecated the New Channel
3634 Payload. The New Channel Payload is now the generic Channel
3637 * Added new argument `mode' to the silc_server_send_new_channel
3638 as it is required in the Channel Payload now.
3640 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3641 and created a new and real SilChannelPayload to represent the
3642 new generic Channel Payload. Implemented the encode/decode
3643 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3645 * Added silc_server_get_client_channel_list to return the list
3646 of channels the client has joined for WHOIS command reply.
3647 Affected file silcd/server.[ch].
3649 * Implemented the channel list sending in the WHOIS command reply
3650 in server and in the client.
3652 Implemented the channel list displaying on the user interface
3653 as well. Affected file silc/client_ops.c.
3655 * Added silc_channel_payload_parse_list to parse list of Channel
3656 Payloads. It returns SilcDList list of SilcChannelPayloads.
3657 Client for example can use this function to parse the list of
3658 channels it receives in the WHOIS command reply. The caller
3659 must free the list by calling silc_channel_payload_list_free.
3660 Affected files lib/silccore/silcchannel.[ch].
3662 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Added one new argument <user mode> to the WHOIS command reply
3665 to return the mode of the user in SILC. Updated the protocol
3668 Implemented it to the server and client.
3670 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Fixed the mode printing on the user interface on joining.
3673 Affected file silc/client_ops.c.
3675 * Implemented the UMODE command and user modes in general to the
3676 client library and to the user interface.
3678 * Implemented the UMODE command to the server.
3680 * The server now sends UNKNOWN_COMMAND error status if client sends
3681 unknown command. Affected file silcd/command.c.
3683 * All server commands now handle the command identifier the right
3684 way when sending the command reply to the client. The client can
3685 use to identify the command replies with the identifier.
3687 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added silc_server_get_client_route to resolve the route to
3690 the client indicated by the client ID. Affected file is
3693 * Added silc_server_relay_packet as general function to relay
3694 packet to arbitrary destination. This deprecates functions
3695 like _send_private_message_key, _relay_notify etc. Affected
3696 file is silcd/packet_send.[ch].
3698 Removed silc_server_send_key_agreement,
3699 silc_server_send_private_message_key and
3700 silc_server_packet_relay_notify functions from the file
3701 silcd/packet_send.[ch].
3705 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3706 server. Affected file silcd/packet_receive.[ch].
3708 * Implemented the KILL command to the client. Implemented the
3709 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3710 Affected files lib/silcclient/command[_reply].c and
3711 lib/silcclient/client_notify.c. Implemented the KILL notify
3712 printing in the user inteface.
3714 * Fixed a lot silc_parse_nick memory leaks from the client
3715 library in the file lib/silcclient/command.c.
3717 * Changed the silc_server_send_notify_on_channels's `sender'
3718 argument from SilcSocketConnection to SilcClientEntry to
3719 check the sender as entry and not as connection object and not
3720 to send to the client provided as argument. The affected file
3721 is silcd/packet_send.[ch].
3723 * The notify packets that are destined directly to the client used
3724 to not to be processed by the server. Now changed that and the
3725 server processes all notify packets. After relaying the packet
3726 to the client the notify packet is processed in the server.
3728 * The silc_server_free_client_data now checks whether there is
3729 pending outgoing traffic for the client and purges the data to
3730 the network before removing the client entry.
3732 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3735 an client is killed from the SILC Network. Updated the protocol
3738 Added new function silc_server_send_notify_killed to the
3739 silcd/packet_send.[ch].
3741 * Added function silc_server_packet_relay_notify to relay notify
3742 packets that are destined directly to a client. In this case
3743 the server does not process the notify packets but merely relays
3744 it to the client. Affected file silcd/packet_send.[ch].
3746 Added also silc_server_packet_process_relay_notify to check
3747 whereto relay the notify. Affected file is
3748 silcd/packet_receive.[ch].
3750 * Implemented the KILL command to the server.
3754 * Added the backup schema desgined last fall to the protocol
3755 specs for everyone to see. The specification is in the
3756 *-spec-xx.txt draft and the packet type definitions for the
3757 backup routers is in *-pp-xx.txt draft. Thusly, added also
3758 new packet type SILC_PACKET_CELL_ROUTERS.
3760 * A big security problem in the implementation discovered. The
3761 signoff of an client did not cause new channel key generation
3762 which it of course should've done. The channel keys must be
3763 always re-generated when client leaves (or signoffs) the channel.
3764 The silc_server_remove_from_channels funtion now handles
3765 the channel key re-generation.
3767 * Added `sender' argument to the silc_server_send_notify_on_channels
3768 to not to send the client provided as argument. Affected file
3769 silcd/packet_send.[ch].
3771 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Implemented OPER and SILCOPER commands into the server and
3776 * Added silc_auth_verify and silc_auth_verify_data to verify
3777 the authentication directly from the authentication payload.
3778 It supports verifying both passphrase and public key based
3779 authentication. Affected file lib/silccore/silcauth.[ch].
3781 * Added `hash' field to the SilcIDListData structure. It is the
3782 hash negotiated in the SKE protocol. Affected file is
3785 * Slight redesigning of the SilcAuthPayload handling routines.
3786 Do not send SilcPKCS but SilcPublicKey as argument.
3788 * Implemented the public key authentication support to the
3789 serverconfig. The public key is loaded from the provided path
3790 and saved as authentication data to void * pointer. Thus,
3791 changed the unsigned char *auth_data to void *auth_data;
3793 * Fixed SHUTDOWN command to send the reply before the server
3794 is shutdown. :) Affected file silcd/command.c.
3796 * Fixed fatal bug in CONNECT command. The hostname was invalid
3797 memory and server crashed. Affected file silcd/command.c.
3799 * Fixed fatal bug in CLOSE command. The server_entry became
3800 invalid but was referenced later in the command. Affected file
3803 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Fixed fatal bug in failure packet handling. Server ignored
3806 the failure and thus crashed when it came.
3810 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3813 that the command may be executed only once in (about) 2 seconds.
3814 The old SILC_CF_LAG flag is same but allows command bursts up
3815 to five before limiting.
3817 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3818 server code. Various commands now includes the CF_LAG_STRICT
3819 flag to disallow any kind of miss-use of the command.
3821 * Fixed the silc_buffer_unformat to not to allocate any data
3822 if the length of the data is zero. It used to allocate the
3823 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3825 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Changed the format of AdminConnection configuration section
3828 in the server. Added username of the admin to the format.
3829 Affected files silcd/serverconfig.[ch].
3831 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3832 to return admin configuration data by host, username and/or
3835 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Implemented WHOWAS command to the server. Added the functions:
3839 silc_server_command_whowas_parse,
3840 silc_server_command_whowas_send_reply,
3841 silc_server_command_whowas_from_client and
3842 silc_server_command_whowas_from_server
3844 * Added <Client ID> argument to the WHOWAS command reply. Updated
3845 the protocol specs accordingly.
3847 * Implemented WHOWAS command and command_reply to the client
3850 Implemented the WHOWAS printing on the user interface.
3852 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Added new argument to the WHOWAS command reply, the real name.
3855 It is an optional argument. Updated the protocol specs.
3857 * Added SilcIDCacheDestructor callback that is registered when
3858 the SilcIDCache is allocated. The callback is called when
3859 an cache entry in the ID Cache expires, or is purged from the
3860 cache. Added into lib/silccore/idcache.[ch].
3862 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3863 to destruct the client entries when the cache entry expires.
3864 Other ID Cache's in server and in the client library ignores
3867 * If the ID Cache entry's `expire' field is zero then the entry
3868 never expires. Added boolean `expire' argument to the
3869 silc_idcache_add function in the lib/silccore/idcache.[ch].
3870 If it is TRUE the default expiry value is used.
3872 * Added silc_server_free_client_data_timeout that is registered
3873 when client disconnects. By default for 5 minutes we preserve
3874 the client entry for history - for WHOWAS command.
3876 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Added support to the server to enforce that commands are not
3879 executed more than once in 2 seconds. If server receives
3880 commands from client more frequently, timeout is registered
3881 to process the commands. Affected file silcd/command.c.
3882 Added new function silc_server_command_process_timeout.
3884 * Changed NICK_NOTIFY handling in client library to check that
3885 if the client's nickname was changed, so there is no need to
3886 resolve anything from the server.
3888 * Removed error printing from the WHOIS and IDENTIFY commands.
3889 If error occurs then it is ignored silently in the client library.
3890 The application, however, may map the received error to
3891 human readable error string. The application currently maps
3892 the NO_SUCH_NICKNAME error to string.
3894 * Made the command status message public to the application. Moved
3895 them from lib/silcclient/command_reply.c to
3896 lib/silcclient/command_reply.h. The application can map the
3897 received command status to the string with the
3898 silc_client_command_status_message function.
3900 * Added check to the server to check that client's ID is same
3901 as the Source ID in the packet the client sent. They must
3904 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Added dist-bzip hook to the Makefile.am to make bzip2
3907 compressed distributions.
3909 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Server now enforces the maximum length for the nickname and
3912 the channel as protocol specification dictates. 128 bytes for
3913 nickname and 256 bytes for channel name.
3915 * Moved the WHOIS printing to the application. The client libary
3916 does not print out the WHOIS information anymore, the application
3917 must do it. Renamed silc_client_command_reply_whois_print to
3918 the silc_client_command_reply_whois_save.
3920 The client's idle time is also sent to the application now, and
3921 the idle is shown on screen.
3923 * Added silc_client_command_reply_identify_save to save the
3924 received IDENTIFY entries.
3926 * Do not check for channel private keys in message sending and
3927 reception if the channel does not have the PRIVKEY mode set.
3928 Affected file lib/silclient/client_channel.c.
3930 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3933 just surfaced after chaning the JOIN procedure.
3935 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Added silc_client_get_clients_by_list to get client entries
3938 from Client ID list, that is returned for example by JOIN
3939 and USERS command replies. The application should use this
3940 function for example when JOIN command reply is received to
3941 resolve the clients already on the channel (library does not
3942 do that anymore as USERS command reply is not used in the JOIN
3943 procedure anymore). Affected files lib/silcclient/silcapi.h and
3944 lib/silcclient/idlist.c.
3946 * JOIN command reply and USERS command reply returns now SilcBuffer
3947 pointers instead of unsigned char pointers when returning
3948 the client list and mode list.
3950 * Added <Client ID> argument to the JOIN command reply, mainly
3951 for the server to identify for which client the command was
3952 originally sent. Updated protocol specs accordingly.
3954 * Added SilcDlist private_key pointer to the SilcChannelEntry
3955 in the client to support the channel private keys. Affected
3956 file is lib/silcclient/idlist.h.
3958 * Added SilcChannelPrivateKey argument to the function
3959 silc_client_send_channel_message so that application can choose
3960 to use specific private ke if it wants to. If it is not provided,
3961 the normal channel key is used, unless private keys are set.
3962 In this case the first (key that was added first) is used
3963 as the encryption key.
3965 * Implemented the support for channel private key handling.
3966 Implemented the following functions:
3968 silc_client_add_channel_private_key,
3969 silc_client_del_channel_private_keys,
3970 silc_client_del_channel_private_key,
3971 silc_client_list_channel_private_keys and
3972 silc_client_free_channel_private_keys
3974 Affected file lib/silcclient/client_channel.c.
3976 * Added the support for the private keys in the channel message
3977 sending and encryption and in the message reception and
3978 decryption. Affected funtions are
3979 silc_client_send_channel_message and silc_client_channel_message.
3981 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Added SKE's key verify callback to the client library's
3984 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3986 * Removed the statement that server (or router) must send USERS
3987 command reply when joining to the channel so that the client
3988 knows who are on the channel. Instead, the client list and
3989 client's mode list is now sent in the JOIN command reply to the
3990 client who joined channel. This is better solution.
3992 * Added function silc_server_get_users_on_channel and function
3993 silc_server_save_users_on_channel to the silcd/server.[ch].
3995 * Removed function silc_server_command_send_users from the
3998 * Do not show topic on the client library anymore. The topic is
3999 sent in the command reply notify to the application and the
4000 application must show the topic now.
4002 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Added client searching by nickname hash into the IDENTIFY and
4005 WHOIS commands in the server as they were clearly missing from
4006 them. Affected file is silcd/command.c.
4008 * Fixed a bug in private message receiving in the client library.
4009 The remote ID was freed and it wasn't supposed, now it is
4012 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Minor fix to the channel payload; allocate the data area, as it
4015 needs to be of specific length.
4017 * If the key agreement port is zero then the operating
4018 system will define the bound port. Affected files are
4019 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4021 * Added new function silc_channel_payload_decrypt into the file
4022 lib/silccore/silcchannel.[ch].
4024 * Moved the channel message etc, check from silc_packet_decrypt
4025 to applications. The library calls now a generic
4026 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4027 when the packet is either normal or special. This was done to
4028 allow more wide range of checking that was not allowed when
4029 the code was in library. Now applications can do virtually any
4030 checks to the packet and return to the library the decision how
4031 the packet should be processed. Affected files are
4032 lib/silccore/silcpacket.[ch].
4034 Added silc_server_packet_decrypt_check to the server and
4035 silc_client_packet_decrypt_check to the client library.
4037 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4038 to send with specified source and destination information.
4040 * Channel message delivery between routers was broken after the
4041 channel key distribution was fixed earlier. The channel key
4042 was used be to distributed to other routers as well which is not
4043 allowed by the protocol. Now this is fixed and channel keys
4044 really are cell specific and the channel message delivery between
4045 routers comply with the protocol specification.
4047 * Fixed various commands in server to check also the global list
4048 for the channel entry and not just the local list. The affected
4049 file silcd/command.c.
4051 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * Added assert()s to buffer formatting and unformatting routines
4054 to assert (if --enable-debug) when error occurs. Affected
4055 file: lib/silcutil/silcbuffmt.c.
4057 * Changed to auto-reconnect to check whether the remote host is
4058 router and register the re-connect timeout if it is. It used
4059 to check that whether we are normal server, but router must do
4060 auto-reconnect with another router as well. Affected file
4063 * Removed the [<key len>] option from CMODE command as the cipher
4064 name decides the key length, nowadays. See the defined ciphers
4065 from the protocol specification.
4067 * Added [<hmac>] option to the CMODE command to define the HMAC
4068 for the channel. Added SILC_CMODE_HMAC channel mode.
4070 * Added [<hmac>] option for the JOIN command so that user can
4071 select which HMAC is used to compute the MACs of the channel
4074 * Added Hmac field to the Channel Message Payload. The integrity
4075 of plaintext channel messages are now protected by computing
4076 MAC of the message and attaching the MAC to the payload. The
4077 MAC is encrypted. Now, it is clear that this causes some
4078 overhead to the size of the packet but rationale for this is that
4079 now the receiver can verify whether the channel message decrypted
4080 correctly and also when private keys are set for the channel the
4081 receiver can decrypt the packet with several keys and check from
4082 the MAC which key decrypted the message correctly.
4084 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4085 lib/silccrypt/silccipher.[ch].
4087 * Added silc_hash_len to return the digest length into the
4088 lib/silcrypt/silchash.[ch].
4090 * Rewrote parts of Silc Channel Payload interface in the
4091 lib/silccore/silcchannel.[ch]. The encode function now also
4092 encrypts the packet and parse function decrypts it.
4094 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Fixed a minor formatting bug in the SKE's key material processing.
4097 It actually might have processed the keys wrong way resulting
4100 * Redefined the mandatory HMAC algorithms and added new algorithms.
4101 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4102 and hmac-md5 truncated to 96 bits. The mandatory is now
4103 hmac-sha1-96. Rest are optional (including the one that used
4104 to be mandatory). Rationale for this is that the truncated HMAC
4105 length is sufficient from security point of view and can actually
4106 make the attack against the HMAC harder. Also, the truncated
4107 HMAC causes less overhead to the packets. See the RFC2104 for
4110 * Added new [hmac] configuration section. The SKE used to use
4111 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4112 is of course wrong. The official names that must be proposed in
4113 the SKE are the ones defined in the protocol specification
4114 (hmac-sha1-96 for example). The user can configure any hmac
4115 using any hash function configured in the [hash] section. At
4116 least, the mandatory must be configured.
4118 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4120 * Added HMAC list to the SKE proposal list. It has now both
4121 hash algorithm list and HMAC list. This makes the protocol
4122 incompatible with previous versions. The SKE now seems to work
4123 the way it is supposed to work, for the first time actually.
4125 * Defined plain Hash algorithms to the protocol specification.
4128 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Implemented support for key agreement packets into the server.
4131 Added functions silc_server_key_agreement and
4132 silc_server_send_key_agreement. Other than these functions,
4133 server has nothing to do with this packet.
4135 * Added support for private message key packets into the server.
4136 Added functions silc_server_private_message_key and
4137 silc_server_send_private_message_key.
4141 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4142 called in the protocol's final callback instead in the END
4143 protocol state. This makes a little more sense and in the same
4144 time in client we can use the same protocol routines for normal
4145 key exchange and to key agreement packet handling as well.
4147 * Added to both client's and server's KE protocol context the
4148 SilcSKEKeyMaterial pointer to save the key material. We will
4149 bring the key material to the protocol's final callback by doing
4150 this. The final callback must free the key material.
4152 * Added SKE's packet_send callback into client's KE protocol
4153 context so that the caller can choose what packet sending function
4154 is used. This way we can use different packet sending when
4155 doing normal SKE when doing key agreement packet handling (in
4156 the key agreement packet handling we do not want to encrypt
4159 * Implemented the responder side of the key agreement routines
4160 in the client. The client can now bind to specified port and
4161 accept incoming key negotiation. The key material is passed
4162 to the application after the protocol is over.
4164 * Implemented the processing of incoming Key Agreement packet
4165 in the client. Added function silc_client_key_agreement to
4168 * Implemented the intiator side of the key agreement routines
4169 in the client. The client can now initiate key agreement with
4170 another remote client. The key material is passed to the
4171 application after the protocol is over.
4173 * Created client_keyagr.c to include all the key agreement
4176 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4177 SILC_TASK_CALLBACK except that it is not static.
4179 * Created client_notify.c and moved the Notify packet handling
4180 from the client.[ch] into that file.
4182 * Created client_prvmsg.c and moved all private message and
4183 private message key routines from the client.[ch] into that file.
4185 * Create client_channel.c and moved all channel message and
4186 channel private key routines from the client.[ch] into that file.
4188 * Changed silc_client_get_client_by_id_resolve to resolve with
4189 WHOIS command instead of IDENTIFY command, in the file
4190 lib/silclient/idlist.c.
4192 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Implemented the SKE's responder side to the Client library.
4196 * When FAILURE is received to the protocol do not trust it
4197 blindly. Register a timeout to wait whether the remote closes
4198 the connection as it should do it, only after that process the
4199 actual failure. This was changed to both client and server.
4201 * Added client_internal.h to include some of the structures
4202 there instead of client.h in lib/silcclient/.
4204 * Added function silc_task_unregister_by_callback to unregister
4205 timeouts by the callback function.
4207 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Some "Incomplete WHOIS info" errors has been appearing on the
4210 log files. Took away the entry->userinfo check from WHOIS
4211 reply sending. The entry->userinfo is now " " if client did not
4212 provide one. I thought this was fixed earlier but something
4213 is wrong still. Let's see if the error still appears.
4215 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Fixed a minor bug in the login when the channel key is
4218 re-generated in the server. It used to generate the key in
4219 wrong order and thus caused problems in the channel traffic.
4221 * Fixed a minor bug in channel key distsribution after
4222 KICK command. The key was not sent to the router even though
4225 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added silc_ske_process_key_material_data as generic routine
4228 to process any key material as the SILC protocol dictates. The
4229 function is used by the actual SKE library but can be used by
4230 applications as well. This relates to the private message keys
4231 and the channel private keys since they must be processed the
4232 same way the normal SILC session keys. The protocol dictates
4233 this. Affected files: lib/silcske/silcske.[ch].
4235 Added also silc_ske_free_key_material to free the
4236 SilcSKEKeyMaterial structure.
4238 * Defined silc_cipher_set_key function to set the key for
4239 cipher without using the object's method function. The affected
4240 files: lib/silccrypt/silccipher.[ch].
4242 * Implemented silc silc_client_add_private_message_key,
4243 silc_client_add_private_message_key_ske,
4244 silc_client_del_private_message_key,
4245 silc_client_list_private_message_keys and
4246 silc_client_free_private_message_keys functions in the
4249 Added functions silc_client_send_private_message_key to send
4250 the Private Message Key payload and silc_client_private_message_key
4251 to handle incoming Private Message Key payload.
4253 * Added Cipher field to the Private Message Key payload to set
4254 the cipher to be used. If ignored, the default cipher defined
4255 in the SILC protocol (aes-256-cbc) is used.
4257 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Removed lib/silcclient/ops.h file.
4261 Redefined parts of the SILC Client Library API. Created new
4262 file silcapi.h that deprecates the ops.h file and defines the
4263 published Client Library API. Defined also private message key
4264 API and channel private key API into the file.
4266 This is the file that the application must include from the
4267 SILC Client Library. Other files need not be included by
4268 the application anymore.
4270 * Added new key_agreement client operation callback and also
4271 defined the Key Agreement library API for the application.
4273 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4276 is used by clients to request key negotiation between another
4277 client in the SILC network. If the negotiation is started it
4278 is performed using the SKE protocol. The result of the
4279 negotiation, the secret key material, can be used for example
4280 as private message key.
4282 Implemented the Key Agreement payload into the files
4283 lib/silccore/silauth.[ch].
4285 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Redefined ciphers for the SILC protocol. Added some new ciphers
4288 and defined the key lengths for the algorithms. Changed the
4289 code accordingly. The default key length is now 256 bits.
4291 * Fixed SKE key distribution function silc_ske_process_key_material
4292 when the key length is more than 128 bits. The default key
4293 length in SILC is now 256 bits.
4295 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4296 to indicate unsupported algorithm.
4298 * Renamed rijndael.c to aes.c and all functions as well.
4300 * Fixed a long standing channel key setting bug in client library.
4301 Weird that it has never surfaced before.
4303 * Fixed bug in channel deletion. If the entire channel is removed
4304 then it must also delete the references of the channel entry
4305 from the client's channel list as the client's channel entry and
4306 the channel's client entry share same memory.
4308 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Implemented CONNECT and SHUTDOWN commands in the client.
4312 * Implemented CLOSE command to the client.
4314 * Added the function silc_idlist_find_server_by_name into the
4315 files silcd/idlist.[ch].
4317 Added the function silc_idlist_find_server_by_conn into the
4318 files silcd/idlist.[ch].
4320 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * DIE command was renamed to SHUTDOWN. Updated the both code
4325 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4326 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4328 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4331 * Added function silc_server_create_connection function to create
4332 connection to remote router. My server implementation actually
4333 does not allow router to connect to normal server (it expects
4334 that normal server always initiates the connection to the router)
4335 so the CONNECT command is only good for connecting to another
4338 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4341 or some other client was kicked from the channel.
4343 Implemented the handling of the notify type to both client
4346 Implemented silc_server_send_notify_kicked to send the KICKED
4347 notify. It is used to send it to the server's primary router.
4349 * Implemented the KICK command into server and client.
4351 * Added `query' argument to the silc_idlist_get_client function
4352 to indicate whether to query the client from server or not if
4355 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4356 to indicate that the client is not channel founder.
4360 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Removed the rng context from SilcPacketContext structure and
4363 changed that the packet routine uses the Global RNG API.
4365 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added support for quit message that client can "leave" on the
4368 channel when it quits the SILC. It is ditributed inside the
4369 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4371 Added silc_server_free_client_data that will take the
4372 signoff message as argument.
4374 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4376 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Updated parts of the protocol specification to keep it up
4381 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4384 payloads in one packet.
4386 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4387 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4388 use now the new List flag.
4390 * Also deprecated the following packet types: REPLACE_ID,
4391 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4393 * Added list support for Notify packet in server.
4395 * Added silc_server_send_notify_channel_change to send the
4396 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4397 the silc_server_send_replace_id.
4399 * Added silc_server_send_notify_nick_change to send the
4400 NICK_CHANGE notify type. Deprecates the function
4401 silc_server_send_replace_id.
4403 * Added silc_server_send_notify_join to send the JOIN notify type.
4404 Deprecates the function silc_server_send_new_channel_user.
4406 * Added silc_server_send_notify_leave to send LEAVE notify type.
4407 Deprecates the function silc_server_send_remove_channel_user.
4409 * Added silc_server_send_notify_cmode and
4410 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4411 types. Deprecates the silc_server_send_set_mode function.
4413 * Added SERVER_SIGNOFF notify type to indicate that server has
4414 quit. This means that all clients on the channel from that
4415 server will drop. This can be also used when netsplit happens.
4417 Deprecated REMOVE_ID packet type since it is not needed anymore
4420 Added silc_server_send_notify_server_signoff to send the
4421 SERVER_SIGNOFF notify type. Deprecates the function
4422 silc_server_send_remove_id.
4424 Added also silc_server_send_notify_signoff to send the
4425 SIGNOFF notify type.
4427 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4428 SILC protocol from this day on. Changed the protocol
4429 specification as well.
4431 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4432 notify type. It is used between routers to notify about
4433 topic changes on a channel.
4435 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4438 * Partly updated the protocol specification to comply with the
4439 changes now made. It is still though a bit outdated.
4441 * The JOIN notify type now takes one extra argument <Channel ID>.
4442 The packet used to be destined to the channel but now the
4443 JOIN type may be sent as list thus it is impossible to
4444 destine it to any specific channel. By adding this argument
4445 it is again possible.
4447 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added CREDITS file. The CHANGES and CREDITS file will appear
4450 in the distribution as well.
4452 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4455 types in the server's silcd/packet_receive.c.
4457 * Implemented CMODE and CUMODE to work in router environment.
4459 * Fixed minor encoding and decoding buglet from the
4460 lib/silccore/silcmode.c.
4462 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4465 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4467 * Changed all SilcConfigServer* and silc_config_server* to
4468 SilcServerConfig* and silc_server_config*, respectively.
4471 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Associated the ID (client or server ID) to the Authentication
4474 Payload to avoid any possibility of forging. Updated the
4475 protocol specification and the code accordingly.
4477 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4479 * The RSA key length is now save to the RsaKey context in the
4480 key generation process in lib/silccrypt/rsa.c. The key length
4481 is now used to figure out the maximum size of the block allowed
4482 to be encrypted/signed.
4484 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4485 is equivalent to the silc_mp_mp2bin but does not allocate any
4488 * Changed silc_mp_mp2bin API to take length argument. If it is
4489 non-zero then the buffer is allocated that large. If zero, then
4490 the size is approximated using silc_mp_sizeinbase, which however
4493 * Created Global RNG API which is global RNG that application can
4494 initialize. After initializing, any routine anywhere in the
4495 code (including library) can use RNG without allocating a new
4496 RNG object. This was done to allow this sort of use of the
4497 RNG in code that has no chance to allocate RNG object. All
4498 applications currently allocate this and many routines in the
4499 library use this. Affected file lib/silccrypt/silcrng.[ch].
4501 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4502 it to use the Global RNG API.
4504 * Defined Authentication Payload into protocol specification that
4505 is used during SILC session to authenticate entities. It is
4506 used for example by client to authenticate itself to the server
4507 to obtain server operator privileges.
4509 Implemented this payload into the lib/silccore/silcauth.[ch].
4510 Implemented also routines for public key based authentication
4511 as the new protocol specification dictates.
4513 Moved definitions of different authentication methods from
4514 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4516 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4517 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4518 silc_pkcs_verify_with_hash functions into the file
4519 lib/silccrypt/silcpkcs.[ch].
4521 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * The client entry's userinfo pointer must be always valid.
4524 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4525 will fail since it requires the userinfo. Now, the userinfo
4526 is allocated as "" if actual userinfo does not exist. Actually,
4527 it must exist and it is totally Ok to drop client connections
4528 that does not announce the userinfo. However, we will make
4529 this workaround for now.
4531 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4532 to return the remote port by socket.
4534 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4537 SILC_SERVER_PENDING_EXEC and added an new macro
4538 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4539 data or when error occurs while processing the pending command.
4541 Added new argument `destructor' into silc_server_command_pending
4542 and to the SilcServerCommandPending object. This destructor is
4543 now called after calling the pending callback or if error occurs
4544 immediately. If error occurs the actual pending callback won't
4545 be called at all - only the destructor. The destructor may be
4546 NULL if destructor is not needed.
4548 All this applies for client library code as well. Similar
4549 changes were made there as well for the pending commands.
4551 In the client, the application must now allocate the
4552 SilcClientCommandContext with the silc_client_command_alloc
4555 * Added reference counter to the SilcServerCommandContext. Added
4556 function silc_server_command_alloc and silc_server_command_dup
4559 Same type of functions added to the client library for the same
4562 * Removed the cmd_ident from IDListData away since it is now
4563 global for all connections. It is the command identifier used
4564 in command sending and with pending commands. The affected file
4567 * Added reference counter to the SilcSocketConnection objecet to
4568 indicate the usage count of the object. The object won't be
4569 freed untill the reference counter hits zero. Currently only
4570 server uses this, and client ignores it. The client must be
4571 set to use this too later. The affected files are
4572 lib/silccore/silcsockconn.[ch]. Added also the function
4573 silc_socket_dup to increase the reference counter.
4575 This was mainly added because it is possible that the socket
4576 is removed underneath of pending command or other async
4577 operation. Now it won't be free'd and proper DISCONNECTING
4578 flags, etc. can be set to avoid sending data to connection that
4579 is not valid anymore.
4581 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4582 the connection. After that it sets SILC_SET_DISCONNECTED.
4583 It is, however, possible that the socket data is not still freed.
4584 The silc_server_packet_process now checks that data is not
4585 read or written to connection that is DISCONNECTED. The socket
4586 get's freed when the reference counter hits zero.
4588 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Changed the client operation API: channel_message operation's
4591 `sender' is now the client entry of the sender, not the nickname
4592 and the `channel' is the channel entry, not the channel name.
4594 In the private_message operation the `sender' is now also the
4595 client entry of the sender not the nickname.
4597 Affected file is lib/silcclient/ops.h and all applications
4598 using the client operations.
4600 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Moved the calling of ops->connect() from connect_to_server_final
4603 into receive_new_id functin since that is the point when the
4604 client is actually allowed to send traffic to network. The
4605 affected file is lib/silcclient/client.c.
4607 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4610 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4611 (if needs broadcasting) instead of broadcasting the packets one
4612 by one which would make a burst in the network traffic.
4614 * Added `broadcast' argument to the functions in silcd/server.[ch]
4615 silc_server_create_new_channel[_with_id] to indicate whether
4616 to send New Channel packet to primary router.
4618 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Added new function into the silcd/server.[ch] files:
4621 silc_server_create_new_channel_with_id to create new channel with
4622 already existing Channel ID.
4624 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4625 lib/silccore/silcpacket.h. This packet is used t send list of
4626 Set Mode payloads inside one packet. Server uses this to set
4627 the modes for the channels and clients on those channels, that it
4628 announced to the router when it connected to it. The protocol
4629 specification has been updated accordingly.
4631 * The silc_server_new_channel did not handle the packet coming
4632 from normal server as it normally does not send that. However,
4633 when it announces its channels it does send it. Implemented
4634 the support for that.
4636 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4637 into the file lib/silccore/id.h.
4639 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Fixed memory leaks in the functions silc_idlist_del_client,
4642 silc_idlist_del_channel and silc_idlist_del_server in the file
4643 silcd/idlist.c. All of those leaked like a sieve.
4645 * Fixed some small memory leaks in the client's function
4646 silc_client_notify_by_server.
4648 * Added functions into silcd/server.c: silc_server_announce_clients,
4649 silc_server_announce_channels and silc_server_announce_server.
4650 These functions are used by normal and router server to announce
4651 to its primary router about clients, channels and servers (when
4652 router) that we own. This is done after we've connected to the
4655 These functions effectively implements the following packet types:
4656 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4657 and SILC_PACKET_NEW_ID_LIST.
4659 * Added new functions into the silcd/packet_receive.[ch]:
4660 silc_server_new_id_list, silc_server_new_channel_list and
4661 silc_server_new_channel_user_list to handle the incoming
4662 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4664 * Added support of changing Channel ID in the function
4665 silc_server_replace_id. If the server that announces a channel
4666 to the router already exists in the router (with same name but
4667 with different Channel ID), router is responsible to send
4668 Replace ID packet to the server and force the server to change
4669 the Channel ID to the one router has.
4671 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4672 client that the Channel ID has been changed by the router. The
4673 normal server sends this to the client. Client must start using
4674 the new Channel ID as the channel's ID.
4676 Implemented handling of this new type into lib/silcclient/client.c
4677 into the function silc_client_notify_by_server.
4679 * Added new function silc_idlist_replace_channel_id into the files
4680 silcd/idlist.[ch] to replace the Channel ID.
4682 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Call silc_server_command_identify_check always when processing
4685 the IDENTIFY command in silcd/command.c
4687 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4690 send keepalive packets. The packet can be sent by clients,
4691 servers and routers.
4693 Added function silc_socket_set_heartbeat into the file
4694 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4695 If not set, the heartbeat is not performed. The actual
4696 heartbeat is implemented in the low level socket connection
4697 library. However, application is responsible of actually
4700 Added silc_server_send_heartbeat to send the actual heartbeat
4701 packet into silcd/packet_send.[ch]. Server now performs
4702 keepalive with all connections.
4704 * Added silc_task_get_first function into lib/silcutil/silctask.c
4705 to return the timeout task with shortest timeout. There was a bug
4706 in task unregistration that caused problems. TODO has been
4707 updated to include that task system must be rewritten.
4709 * The client library will now resolve the client information when
4710 receiving JOIN notify from server for client that we know but
4711 have incomplete information.
4713 * Rewrote parts of silc_server_remove_from_channels and
4714 silc_server_remove_from_one_channel as they did not remove the
4715 channel in some circumstances even though they should've.
4717 * Encryption problem encountered in server:
4719 The LEAVE command used to send the Channel Key packet to the
4720 router immediately after generating it. However, the code
4721 had earlier sent Remove Channel user packet but not immediately,
4722 ie. it was put to queue. The order of packets in the router
4723 was that Channel Key packet was first and Remove Channel User
4724 packet was second, even though they were encrypted in the
4725 reverse order. For this reason, MAC check failed. Now, this
4726 is fixed by not sending the Channel Key packet immediately but
4727 putting it to queue. However, this is more fundamental problem:
4728 packets that are in queue should actually not be encrypted
4729 because packets that are sent immediately gets encrypted
4730 actually with wrong IV (and thus MAC check fails). So, packets
4731 that are in queue should be encrypted when they are sent to
4732 the wire and not when they put to the queue.
4734 However, the problem is that the current system has not been
4735 designed to work that way. Instead, the packet is encrypted
4736 as soon as possible and left to the queue. The queue is then
4737 just purged into wire. There won't be any fixes for this
4738 any time soon. So, the current semantic for packet sending
4741 o If you send packet to remote host and do not force the send
4742 (the packet will be in queue) then all subsequent packets to the
4743 same remote host must also be put to the queue. Only after the
4744 queue has been purged is it safe again to force the packet
4747 o If you send all packets immediately then it safe to send
4748 any of subsequent packets through the queue, however, after
4749 the first packet is put to queue then any subsequent packets
4750 must also be put to the queue.
4752 Follow these rules and everything works fine.
4754 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Added new function silc_server_remove_clients_by_server to
4757 remove all client entries from ID list when the server connection
4758 is lost. In this case it is also important to invalidate all
4759 client entires as they hold the invalid server entry. This
4760 fixes fatal bug when server has lost connection and will reconnect
4763 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4765 * Made some sanity checks to silc_server_daemonise like to check
4766 whether the requested user and group actually exists.
4768 * Added sanity check to SKE's silc_ske_responder_finish to check
4769 that the public and private key actually is valid.
4771 * Invalidate the client's nickname when receiving Replace ID
4772 packet and the Client ID is being replaced. This means that the
4773 server will query the nickname if someone needs it (client)
4776 * Sort the ID Cache in client library when the ID Cache data
4777 has changed (needs sorting).
4779 * Do not allow for SILC client to create several connections to
4780 several servers. The client does not support windows right now
4781 and generating multiple connections causes weird behaviour.
4783 Irssi-silc client does support windows and can handle several
4784 connections without problems, see: www.irssi.org and SILC plugin.
4786 * Fixed some places where client was added to the IDList. The
4787 rule of thumb is following (in order to get everything right):
4788 If the client is directly connected local client then the
4789 `connection' argument must be set and `router' argument must be
4790 NULL to silc_idlist_add_client function. If the client is not
4791 directly connected client then the `router' argument must
4792 bet set and the `connection' argument must be NULL to the
4793 silc_idlist_add_client function.
4795 * The funtion silc_server_packet_send_local_channel actually did
4796 not check whether the client was locally connected or not. It
4797 does that now. Fixed a bug related to LEAVE command.
4799 * Fixed Remove Channel User payload parsing bug in server's
4800 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4802 * The server's silc_server_save_channel_key now checks also the
4803 global ID list for the channel as it might not be in the local
4804 list. Fixed a bug related to LEAVE command.
4806 * Is this the end of the [<unknown>] buglet that has been lurking
4807 around for a long time? A little for loop fix in server's
4808 silc_server_command_whois_parse that is used by both IDENTIFY
4809 and WHOIS command. At least, this was a clear bug and a cause
4810 of one type of [<unknown>] buglet.
4812 * WHOIS and IDENTIFY commands call the function
4813 silc_server_command_[whois/identify]_check function even if
4814 we are not router server.
4816 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4818 * Added --with-gmp configuration option. If set the GMP
4819 is always compiled in the SILC source tree. If not set then
4820 it is checked whether the system has the GMP3 installed. If
4821 it has then the GMP won't be compiled (the system's headers
4822 and library is used), if it doesn't have it then the GMP is
4823 compiled in the SILC source tree.
4825 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Changed RSA private exponent generation to what PKCS #1
4828 suggests. We try to find the smallest possible d by doing
4829 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4830 not security fix but optimization.
4832 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Added new config entry [Identity] to fork the server and run
4835 it as specific user and group. A patch from Bostik.
4837 * Imported Dotconf configuration library into lib/dotconf.
4838 This will be used to create the SILC configuration files later.
4839 It will appear in the distsribution after this commit.
4841 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * A big code auditing weekend happening. Auditing code for
4844 obvious mistakes, bugs and errors. Also, removing any code
4847 Removed files for being obsolete:
4849 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4850 inline in the file lib/silcutil/silcbuffer.h)
4852 o lib/silcutil/silcbufutil.c (the header has inline versions)
4854 Changed code to fix possible error conditions:
4856 o The buffer formatting routines now check that the destination
4857 buffer really has enough space to add the data. This applies for
4858 both buffer formatting and unformatting
4859 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4860 unformatting was changed to accomodate following rules:
4861 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4862 sent to the function while XXX_*STRING will not allocate or copy
4863 the data into the buffer. Instead it sets the pointer from the
4864 buffer into the pointer sent as argument (XXX_*STRING used to
4865 require that the pointer must be allocated already). This change
4866 makes this whole thing a bit more consistent and more optimized
4867 (note that the data returned in the unformatting with XXX_*STRING
4868 must not be freed now). The routines return now -1 on error.
4870 o Tried to find all code that use buffer_format and buffer_unformat
4871 and added return value checking to prevent formatting and
4872 especially unformatting errors and possible subsequent fatal
4875 o Changed ske->x and ske->KEY to mallocated pointers in
4876 lib/silcske/silcske.h. Fixed possible data and memory leak.
4878 o Added return value checking to all *_parse* functions. Fixed
4879 many memory leaks as well.
4881 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4882 so that buffer overflows would not happen. All code now also
4883 checks the return value as it can fail.
4885 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * Added reconnection support to server if the normal server looses
4888 its connection to the router (for example if router is rebooted).
4889 The server performs normal reconnection strategy implemented
4890 to the server. Affected file silcd/server.c.
4892 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Added new packet type SILC_PACKET_SET_MODE that is used to
4895 distribute the information about changed modes (for clients,
4896 channels and clients channel modes) to all routers in the
4897 network. Updated the protocol specification accordingly.
4899 Added functions into silcd/packet_send.c and
4900 silcd/packet_receive.c: silc_server_send_set_mode,
4901 silc_server_set_mode.
4903 Added new files silcmode.[ch] into lib/silccore that implements
4904 the encoding and decoding of Set Mode Payload. Added new type
4905 SilcSetModePayload. Moved the definitions of different modes
4906 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4908 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Oops, a little mistake in server's connection authentication
4911 protocol. The protocol is not ended with FAILURE but with
4912 SUCCESS if the authentication is Ok. :) Affected file is
4915 * Implemented NICK_CHANGE notify handling in server in the file
4916 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4917 the local clients on the channel. After the changing nickname
4918 in router environment snhould work and the [<unknown>] nickname
4919 should appear no more.
4921 The silc_server_replace_id function that receives the Replace ID
4922 payload now sends the NICK_CHANGE notify type also in the file
4923 silcd/packet_receive.c
4925 * Changed WHOIS and IDENTIFY command to support the maximum amount
4926 of arguments defined in protocol specs (3328 arguments). This
4927 fixed a bug that caused problems when there were more than three
4930 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Added extra parameter, command identifier, to the
4933 silc_client_send_command so that explicit command identifier
4936 Changed that ID list routines uses specific command identifier
4937 when sending WHOIS/IDENTIFY requests to the server so that they
4938 can be identified when the reply comes back.
4940 Affected files lib/silcclient/command.[ch],
4941 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4943 * Added `sender' argument to silc_server_packet_send_to_channel
4944 to indicaet the sender who originally sent the packet to us
4945 that we are now re-sending. Ignored if NULL. Affected file
4946 silcd/packet_send.[ch].
4948 * Added some server statistics support in silcd/server_internal.h
4949 SilcServerStatistics structure and around the server code. Also
4950 send some nice statistics information when client is connecting
4953 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Fixed channel ID decoding in server's JOIN command reply in
4956 silcd/command_reply.c
4958 * Fixed braodcasting of replace ID payload to not to send it if
4959 we are standalone server in silcd/packet_receive.c.
4961 * Fixed all channel message sending routines to not to send
4962 packets to clients that has router set, since they are routed
4963 separately in the same function earlier. Affects file
4964 silcd/packet_send.c and all channel packet sending functions.
4966 * In USERS reply, res_argv[i] are not allocated, the table
4967 is allocated. Thus changed that free the table, not its
4970 * In server's whois_check and identify_check if the client is
4971 locally connected do not send any WHOIS commands - they are not
4974 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Fixed some minor bugs in client when sending WHOIS command. The
4977 arguments was in wrong order.
4979 * Removed statis function add_to_channel from server in
4980 silcd/command.c that was previously used with the joining but
4983 * Tested USERS command in router environment successfully with two
4984 routers, two servers and two clients.
4986 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Reorganized the USERS command and command reply in client library
4989 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4990 When the command is given by user we register a pending command
4991 callback that will reprocess the command after the reply has been
4992 received from the server. When reprocessing the packet we then
4993 display the information. Thus, the USERS information is displayed
4994 now in the command callback instead of in the command reply
4995 callback. The processing of the command is same as previously
4996 when server has sent the command reply in the JOINing process.
4998 * Added to USERS command in silcd/command_reply.c to join the client,
4999 we didn't use to know about, to the channel after we've created
5000 a client entry for it. Also, for clienet we did know already still
5001 check whether it is on the channel or not and add it if not.
5003 * Removed silc_server_command_join_notify as the function and its
5006 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Changed the client's pending command handling to the same as the
5009 server's pending command handling. It is also now possible to
5010 execute command reply functions from other command reply
5011 function as the function callbacks for commands and command
5012 replies are one and same. The pending commands are not static
5013 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5014 in client connection context. Thus, pending commands are server
5015 connection specific as it is convenient.
5017 Changed the function silc_client_command_pending and
5018 silc_client_command_pending_del and added new function
5019 silc_client_command_pending_check. Removed the
5020 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5023 * Added cmd_ident, current command identifier, to the client
5024 connection context in lib/silcclient/client.h to keep track on
5025 command identifiers used in command sending. Client's command reply
5026 function handling now supports the mandatory command identifiers.
5028 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5029 funtions in client to fully support pending command callbacks.
5031 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5032 as one of the arguments to the application in the command reply
5035 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5036 before first releasing SILC but came back. Now it is removed again
5037 and should come back nomore. The FORWARDED flag was used only
5038 by the JOINing procedure by forwarding the command packet to router.
5039 Now, the JOINing procedure has been changed to more generic (due
5040 to various router environment issues) and FORWARDED is not needed
5041 anymore for anything. The protocol specification is yet to be
5044 Now, removed silc_server_packet_forward from server and the flag
5045 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5047 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Renamed NAMES command to USERS command. The NAMES was named that
5050 due to historical reasons. Now it is renamed. Also, rewrote
5051 parts of the USERS command. The nickname list is not sent anymore
5052 by the server. Only Client ID and mode lists are sent in the USERS
5053 command. Changed this also to the protocol specification.
5055 The client now resolves the names and stuff after it receives
5056 the USERS list from the server when joining to the channel.
5058 * WHOIS and IDENTIFY commands has been changed to support multiple
5059 Client ID's per command. One can now search for multiple users
5060 in the network by sending only one WHOIS or IDENTIFY command.
5061 Changed the code and the protocol specifications.
5063 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5064 uses silc_server_command_whois_parse to parse the request. */
5066 * If normal server, do not parse the WHOIS and IDENTIFY requests
5067 before sending it to the router. Saves some time.
5069 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Fixed JOIN command on client library. Wrong number of arguments
5072 used to crash the client.
5074 * Added silc_server_channel_has_global function to check whether
5075 channel has global users or not.
5077 * Added silc_server_channel_has_local function to check whether channel
5078 has locally connected clients on the channel.
5080 * The silc_server_remove_from_one_channel now checks whether the
5081 channel has global users or not after given client was removed from
5082 the channel. It also checks whether the channel has local clients
5083 on the channel anymore. If it does not have then the channel entry
5084 is removed as it is not needed anymore.
5086 * The silc_server_notify now checks on JOIN notify whether the joining
5087 client is one of locally connected or global. If it is global then
5088 the channel has now global users on the channel and that is marked
5089 to the channel entry. Also, it now saves the global client to
5090 global list who is joining and JOINs it to the channel. This is
5091 for normal server, that is.
5093 Changed silc_server_send_notify_on_channel,
5094 silc_server_packet_relay_to_channel and
5095 silc_server_packet_send_to_channel check if we are normal server
5096 and client has router set (ie. global client) do not send the
5097 message to that client, as it is already routed to our router.
5099 * Implemented LEAVE notify type handling in silc_server_notify
5102 * Tested LEAVE command in router environment successfully. Tested
5103 with two routers, two servers and two clients.
5107 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5109 * Implemented SIGNOFF notify type handling in silc_server_notify
5112 * silc_server_remove_id now removes the client entry from all channels
5113 it has joined and thusly sends SIGNOFF notify type.
5115 * Rewrote the NAMES list generation in server by removing two excess
5116 loops. The lists are created now inside one loop.
5118 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * silc_server_remove_channel_user checks now also global list
5121 for channel and client.
5123 * silc_server_new_channel_user checks now both local and global
5124 list for channel and client. Fixed a bug in client id decoding.
5125 Used to decode wrong buffer.
5127 * silc_server_channel_message checks now both local and global
5128 list for channel entry.
5130 * Tested channel joining (hence JOIN) in router environment
5131 successfully. Tested with two routers, two servers and two
5134 * Tested channel message sending in router environment successfully.
5136 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Added silc_server_save_channel_key into server.[ch] to save the
5139 received channel key in Channel Key payload processing. It is
5140 also used in JOIN command reply handling.
5142 Equivalent function silc_client_save_channel_key added into
5143 client.[ch] into client library.
5145 * Changed JOIN command reply to send information whether the channel
5146 was created or not (is existing already) and the channel key
5147 payload. Changed protocol specs accordingly.
5149 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5150 the request was sent by ID and not by nickname. Crashed on
5153 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5156 now correctly save the received data.
5158 * silc_server_free_sock_user_data now notifies routers in the
5159 network about entities leaving the network.
5161 At the same time implemented functions silc_server_remove_id
5162 and silc_server_send_remove_id to receive and send REMOVE_ID
5163 packets. The packet is used to notify routers in the network
5164 about leaving entities. The ID removed will become invalid in
5167 * Added function silc_idlist_del_server into server. Removes and
5168 free's server entry from ID list.
5170 * silc_server_private_message function now checks, if we are router,
5171 that the destination ID really is valid ID, naturally.
5173 * In router when NEW_ID packet is received (for new client) the
5174 hash of the Client ID is saved in the ID Cache but the
5175 client->nickname is set to NULL, instead of putting the hash
5178 IDENTIFY command now also checks that client->nickname must be
5179 valid. If it is not if will request the data from the server who
5180 owns the client. Added new function
5181 silc_server_command_identify_check.
5183 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5184 to set the command to already allocated Command Payload.
5186 * Tested private message sending in router environment with two
5187 routers, two servers and two clients. Fixed minor bugs and now
5190 * Fixed segfault from client's NAMES command. Used to crash if
5193 * Forwarded packets must not be routed even if it is not destined
5194 to the receiver. Changed server code comply with this.
5196 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Added `require_reverse_mapping' boolean value to ServerParams
5199 structure. If TRUE (not default) the server will require that
5200 the connecting host has fully qualified domain name.
5202 If the reverse mapping is not required and hostname could not be
5203 found the IP address is used as hostname.
5205 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Implemented version string checking to both client and server.
5208 The check is incomplete currently due to the abnormal version
5209 strings used in development version of SILC.
5211 * Changed all command functions in server to use the new
5214 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Changed char *data to unsigned char *data in ID Cache system to
5217 support binary data as ID Cache data. Changed code to support
5218 binary data in lib/silccore/idcache.c.
5220 * Renamed silc_server_packet_relay_command_reply to
5221 silc_server_command_reply as it is normal packet receiving
5222 function. Rewrote the function to accept command replys for
5223 servers and not only for clients.
5225 * Mark remote router always as registered server if we are connecting
5226 to it. Otherwise, commands sent by the router to us are ignored.
5228 * All ID List find routines now returns the ID Cache Entry pointer
5229 as well if requested.
5231 * WHOIS command works now in router environment, tested with two
5232 routers, two servers and two clients.
5234 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5235 in router environment (as it is almost equivalent to WHOIS) but
5236 hasn't been tested thoroughly. Added new functions:
5238 silc_server_command_identify_parse
5239 silc_server_command_identify_send_reply
5240 silc_server_command_identify_from_client
5241 silc_server_command_identify_from_server
5243 * Disabled route cache adding because adding two different ID's with
5244 same IP replaces the old cache entry thus giving wrong route.
5245 The entry->router->connection is always the fastest route anyway
5246 so route cache may not be needed. Of course, new routes maybe
5247 established after receiving the ID when the entry->router->connection
5248 might not be anymore the most optimal.
5250 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Add route cache for received ID for fast routing.
5254 * Added silc_server_packet_route to route received packet on router
5255 that is not destined to us.
5257 * Renamed silc_server_get_route to silc_server_route_get.
5259 * Added id_string and id_string_len fields into SilcServer to
5260 include encoded ServerID for fast comparing without excess
5261 encoding of the ID's.
5263 * Cleaned up WHOIS command on server side. Added following static
5266 silc_server_command_whois_parse
5267 silc_server_command_whois_check
5268 silc_server_command_whois_send_reply
5269 silc_server_command_whois_from_client
5270 silc_server_command_whois_from_server
5272 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5273 arguments in command replies. All command functions should be
5274 updated to use this macro.
5276 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Minor typo fixes on command reply handling on server.
5280 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Added silc_server_command_add_to_channel internal routine to add
5283 the client to the channel after router has created the channel and
5284 sent command reply to the server.
5286 * Added generic silc_server_send_command to send any command from
5289 * Use static buffer with ID rendering instead of duplicating data.
5291 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Fixed a channel user mode bug when joining to a channel server gave
5294 everybody channel founder rights, oops.
5296 * We mark ourselves as the router of the incoming server connection
5297 if we are router ourselves. This way we can check in some packet
5298 sending functions whether it is locally connected server. For
5299 incoming router connections we put NULL.
5301 * For router sending packets locally means now always sending the
5302 packet cell wide; to local clients and local servers. For normal
5303 server sending packet locally means sending it to only local
5306 * Fixed the JOIN command to really work in router environment. If the
5307 channel is created it is always created by the router. Router is
5308 also responsible of making the initial joining to the channel,
5309 sending JOIN notify to the sending server and distributing
5310 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5311 does not exist server doesn't do anything else but forward the
5312 command to the router which performs everything.
5314 * Added silc_server_send_channel_key function to send the Channel Key
5317 * Added silc_server_create_channel_key to create new channel key. The
5318 channel key is now re-generated everytime someone joins or leaves
5319 a channel, as protocol dictates. Note: channel->key_len is the
5322 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5325 packet_receive.[ch] to separate packet sending and receiving
5326 routines. The server.[ch] now includes everything else including
5327 actual packet processing (writing and reading data) and other
5330 Renamed silc_server_private_message_send_internal to
5331 silc_server_send_private_message. The routine is still though
5332 used only to relay private messages as server does not send
5333 private messages itself.
5335 Renamed silc_server_new_channel to silc_server_create_new_channel
5336 and added new function sicl_server_new_channel that handles the
5337 incoming New Channel packet. Added also new sending function
5338 silc_server_send_new_channel to send New Channel Payload.
5340 * Added new function silc_server_notify to process incoming notify
5341 packet to the server/router. Server may then relay the notify
5342 to clients if needed.
5344 * Added new function silc_server_new_channel_user to process incoming
5345 New Channel User packet. Router will redistribute the packet and
5346 send JOIN notify to its local clients and locally connected servers
5347 if needed. Normal server will send JOIN notify to its local client
5348 on same channel when received this packet. Added also corresponding
5349 sending function silc_server_send_new_channel_user to sent the
5352 * Added boolean route argument to send_notif_to_channel and
5353 packet_send_to_channel functions to attempt to route the packet
5354 if it is TRUE and send only locally if it is FALSE.
5356 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * silc_server_replace_id now broadcasts the received replace ID
5359 packet if it is not broadcast packet already. The router must
5360 broadcast to inform other routers about changed ID.
5362 * Added backpointer to server's router into SilcServer context in
5363 silcd/server_internal.h.
5365 * Fixed silc_server_packet_broadcast to send correct broadcast
5368 * The channel key is now distributed to the local client as soon
5369 as it is received from the router (in router environment) so that
5370 no other packet may be sent for the channel until client has
5373 * silc_server_remove_channel_user now broadcasts the received
5374 Remove Channel User packet if it is not broadcast packet already.
5375 The router must broadcast to inform other routers about removed
5378 * Added users field into SilcPacketContext that is a reference count
5379 of the context. One can increase the reference count by calling
5380 silc_packet_context_dup which is now changed to just increase the
5381 reference count instead of duplicating the data. The reference
5382 count is decresed by calling silc_packet_context_free that will
5383 free the data after the reference count hits zero.
5385 For now on the packet context and everything allocated into it
5386 (including the raw packet from network) must be freed by calling
5387 the new silc_packet_context_free function. Added also new function
5388 silc_packet_context_alloc that must be used now to allocate the
5389 context. This also means that if a routine is asynchronous from
5390 silc_[client/server]_packet_parse_type the packet context must
5391 be duplicated by calling silc_packet_context_dup. Otherwise it
5392 gets free'd after silc_[client/server]_packet_parse_type returns.
5393 Also, one must remember that if packet is duplicated then its
5394 reference count must be decresed by calling the free function as
5395 many times as it was duplicated.
5397 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5398 from both client and server.
5400 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Made joining to a channel working in router environment.
5404 * Cleaned up JOIN command on server side and create function
5405 silc_server_command_join_channel internal routine to make the
5408 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Changed silc_command_pending list to SilcDList. Also, added
5411 `ident' field to SilcServerCommandPending structure to identify
5412 the reply and to call correct callback.
5414 Added silc_server_command_pending_check function to replace the
5415 corresnponding macro. The silc_command_pending list is not
5418 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5419 to set identifier to previously allocated Command Payload. It
5420 is used to set identifier for command when resending Command
5423 * Added silc_command_payload_encode_payload to encode Command
5424 Payload buffer from SilcCommandPayload structure.
5426 * Added silc_argument_payload_encode_payload to encode Argument
5427 payload buffer from SilcArgumentPayload structure.
5429 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Changed WHOIS command to support router connection on server side.
5432 The whois request is always sent to router unless the server is
5433 standalone server. After server has received the reply from the
5434 router will it send the reply to the client.
5436 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5437 broadcast received broadcast packet. The function is used only
5438 by router. The broadcast packet is always sent to the router's
5441 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5442 render given ID to printable string, for log files for example.
5444 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Made basic router to router connections working. At least they
5447 can now connect to each other but nothing really works the way
5448 they are supposed - yet.
5450 * Added new initiator token to RouterConnection configuration
5451 file in silcd/serverconfig.[ch]. It is used to tell whether we
5452 are the initiator to the remote router or whether we'll expect
5453 the other end to connect.
5455 * Moved registering of listener task to silc_server_init, hence
5456 the server starts listenning as soon as it is run, even if it
5457 does not have connections to other routers. Let's see how well
5460 * Changed default connection retry timeouts for more suitable in
5463 * Removed cipher and such arguments from silc_idlist_add_client
5464 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5465 Added new function silc_idlist_add_data to add the keys and stuff
5468 * Added SilcIDListData structure and added it to SilcClientEntry
5469 and SilcServerEntry as their first field in the structure. This
5470 way we can explicitly cast the ID entries to the SilcIDListData
5471 structure and get common data for the entries. In past, we had
5472 to first check what type of connection it is and then cast it to
5473 correct ID entry type. Now, we can directly cast the opaque
5474 pointer to the SilcIDListData (no matter what ID entry it actually
5475 is) and get the data needed.
5477 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5480 in some circumstances even if threre were timeout tasks, though not
5481 IO tasks, but tasks anyway. Now fixed.
5483 * Defined SilcServerConnection structure to hold connection specific
5484 stuff about directly connected servers and routers. The definition
5485 is currently in silcd/server_internal.h. I thought about having
5486 a bit more important role fro this struct but for now it is used
5487 only when connecting to other server (or router actually).
5489 * Added connecting retry support in server when connecting to
5490 router(s). The retry feature implement exponential backoff
5491 algorithm. Also, added SilcServerParams structure to hold default
5492 parameters for server. For now, it include these retry settings
5493 and are hard coded. After server is moded to be as Silc Server
5494 Library this structure will be more important.
5496 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Changed client librarys channel->clients table to SilcList and
5499 changed code accordingly.
5501 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Changed client's channel table to SilcList and changed code
5504 accordingly. Also changed SilcChannelClientEntry to include back-
5505 pointer to the channel so that client entry can use that structure
5506 as list as well and we have fast cross-reference to the channel.
5507 This change dramatically decreased the complexity of channel
5508 handling with client entry and vice versa (removed one extra
5509 loop when searching for channel entry from many functions).
5511 * Changed server->sim from table to SilcDList and changed code
5514 * NAMES command can now be used from user interface. It will show
5515 the user list on the channel, neatly.
5517 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5518 Code now saves realname of the user if it becomes available.
5520 * Renamed configure.in to configure.in.pre and made ./prepare
5521 script to automatically add correct version string to
5522 configure.in which it creates from configure.in.pre.
5524 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * NAMES command reply now shows users mode with the nickname when
5529 * Moved silc_client_ch[u]mode[_char] functions from
5530 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5531 place sucks, they are utility functions and should be in some
5534 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5536 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5539 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Added TRQ (efficient deque and list library) into lib/trq. This is
5544 a very good list library that is currently used in the SILC. Defined
5545 SilcList API over the library because I didn't like the API very
5546 much. See lib/trq/silclist.h for the API and examples of how to
5547 use the API. Fixed various places in the code to use the new
5548 SilcList API. The SilcList is meant for lists that has a structure
5549 already defined as a list. It is not suitable to add just some
5550 context to the list (in TRQ, the context is the list actually).
5552 So, I defined SilcDList that can be used for the purpose where
5553 predefined list structure does not exit. This can be used as
5554 such list. Now some context just can be added to the SilcDList.
5555 Currently this list is not used in the SILC just yet, though there
5556 are a lot places where this can replace dynamically allocated
5557 tables and I will fix these places, later, to use SilcDList.
5558 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5559 and use TRQ internally).
5561 Also fixed some annoying warning messages that the original TRQ
5562 code generated. Also minor changes to TRQ's Makefile.in.
5564 * Added support for querying by Client ID to both WHOIS and
5565 IDENTIFY commands into server, as required by the protocol.
5567 * Removed method function pointers from SilcBuffer structure. They
5568 weren't used to anything and just increased the context size for
5569 no good reason. This change also made silc_buffer_alloc and
5570 silc_buffer_free functions inline functions.
5572 * Disabled command flooding detection support until it's fixed so
5573 that it accepts commands in but does not execute them more than once
5576 * Added silc_net_localhost(), to return local hostname, into
5577 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5578 that must be initialized before calling silc_client_init.
5580 * Added new function: silc_server_send_notify_on_channels to send
5581 notify messages to all channels client has joined. It is assured
5582 that the message is sent only once per client.
5584 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5585 lib/silcutil/silcutil.[ch] as silc_format function. The new
5586 function is generic and is used by server as well, not only by
5587 the logging routines.
5589 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5590 the provided version string was not acceptable. Added new function:
5591 silc_ske_check_version into lib/silcske/silcske.h. The function
5592 must be implemented by the application (client or server) and it
5593 does not reside in the SKE library. The function checks the version
5594 string remote end sent.
5596 * Added back pointers (to opaque context and to SilcSocketConnection)
5597 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5599 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5600 duplicate packet context structure.
5602 * Changed `notify' client operation to send same arguments as client
5603 receives from server except for ID's. ID's are mapped to correct
5604 ID entry and that is returned. Also, if channel entry is not sent
5605 by server but the notify is for channel the channel entry is sent
5606 to application (otherwise application doesn't know that it is for
5607 channel (library gets it from packet's Destination ID)).
5609 * Added silc_client_remove_from_channels into client library to
5610 remove a client from all channels it has joined to. Used when
5611 received SIGNOFF notify from server. Added also new function
5612 silc_client_replace_from_channels to replace old ID entry with
5613 new ID entry on all channels. Used when received NICK_CHANGE
5616 * Fixed ID Cache list handling in silc_idlist_get_client in
5617 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5618 to get (or query) client by ID.
5620 * Updated TODO list.
5622 * Added connection authentication status message defined by the
5623 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5624 support for these into the code in client and server side.
5626 * Added generic function silc_client_send_command to send any command
5627 with variable argument list. Application should use this function
5628 to send commands if the command functions provided by the library
5629 does not suite for the application's user interface needs.
5631 * Added new `failure' client operation. Application is notified about
5632 received failure packet if client is executing a protocol. In this
5633 case the protocol's execution has failed.
5635 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5636 is required by the protocol.
5638 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5639 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5642 * Added status flag to SilcSKE object to indicate realtime status
5643 of the SKE protocol.
5645 * Application receives now exactly same command reply arguments as
5646 the library receives from server. However, if ID is received the
5647 corresponding ID entry is returned to the application (eg. Client
5648 ID is mapped to correct SilcClientEntry entry and that is returned).
5649 Changed command_reply client operation due to this change.
5651 * Changed all ID's in commands and in command replys as ID Payloads.
5652 Change affected both client and server side codes.
5654 All ID's sent in SILC network (with execption of ID's in SILC
5655 Packet header) are sent in ID Payload to support variable length
5658 * Server now notifies nick changes and notifies all clients on
5659 the channels about the new nickname (about the new Client ID,
5662 * Implemented CMODE command to change channel modes. Supports all
5663 channel modes defined by the protocol specs except ban and invite
5664 lists. (Also, private channel key mode is supported but support for
5665 setting private channel key in client is missing, thus, this mode
5666 has no effect on client side (except that server requires that the
5667 client uses private channel key and normal channel traffic does not
5670 Also, invite mode works per se, but INVITE command does not work
5671 yet correctly, so you can set channel as invite only channel but
5672 inviting clients to the channel does not work (it is yet to be
5673 thought what's the best way to do it).
5675 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5676 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5677 Implemented CUMODE command to change user's mode on the channel.
5678 Supports all modes defined by the protocol specs.
5680 * Added NAMES command reply to return users modes on the channel.
5682 * Removed unnecessary and slow ciphers from lib/silccrypt.
5684 * Set SO_KEEPALIVE option to connection sockets by default.
5686 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5688 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5689 redefined the Notify Payload into protocol specs.
5691 * Added silc_id_payload_parse_id to get ID directly from raw
5694 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5697 accept searching by Client ID as well.
5699 * Added support for LEAVE and SIGNOFF notify types in client library.
5701 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5702 to parse ID Payload from raw data.
5704 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Added flags parameter into silc_ske_assemble_security_properties
5707 function in lib/silcske/silcske.[ch].
5709 * Changed notify client operation to fit better for notify messages
5710 sent by server. The notify payload received from server is now
5711 passed to the application (after parsing it to SilcNotifyPayload).
5712 It is application's responsibility to retrieve the arguments
5713 from the payload and show the message the way it wants. The message
5714 sent by server is implementation specific.
5716 * Changed public keys to comply with the protocol specification.
5717 Old public keys are not supported anymore and are not compatible.
5719 * Removed nickname from Channel Payload as the latest draft removed
5720 it. The client must resolve the nickname from the NAMES command
5721 reply received when it joined the channel.
5723 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5725 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed some errors in protocol specification drafts.
5729 * Created lib/silccore/silcnotify.c to implement Notify Payload
5730 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5731 generic payloads described by protocol specifications. The file
5732 includes implementations for ID Payload and Argument Payload.
5734 * Changed Command Payload implementation to use the new Argument
5735 Payload. Changed command_xxxx_payload to command_payload_xxxx
5736 to comply with SILC coding conventions.
5738 * Added suppport for Argument Payload handling in Notify Payload
5739 implementation as protocol requires it. Added the new support
5740 into server and client lib as well.
5742 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Added support for multiple nicknames on same channel. [n] is
5745 added locally to the nickname if there are more than one same
5746 nicknames on the channel.
5748 * Server now sends all nicknames that matched WHOIS request.
5749 Client also shows the list received from server.
5751 * Added TOPIC command to client side. User can now set and show
5752 current topic on channel.
5754 * Added MOTD command to client and server. Also, server sends the
5755 motd when client connects to the server.
5757 * Changed version strings to comply ISO 8601.
5759 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Fixed protocol error handling in client library. It should now
5762 cope even if the SKE fails for some reason.
5764 * Made new protocol specification drafts for submitting to IETF.
5766 * Implemented TOPIC command to server in silcd/command.c.
5768 * Added two new notify types into lib/silccore/silcnotify.h:
5769 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5770 notify nickname change and topic setting/change on a channel.
5772 * API change of command_reply operation in client library. The
5773 application gets now the status type received from server as well.
5775 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5779 * Cras fixed and optimized the packet handling even further and
5780 it should work now. Minor change to the prototype of function
5781 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5783 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Added new function into lib/silcutil/silcschedule.[ch]:
5786 silc_schedule_with_fd to select() a specified fd. The function
5787 returns after timeout expires or data arrives or goes. The
5788 function is used by packet routines to wait that all data is
5789 received from network.
5791 * Fixed data reading from network in lib/silccore/silcpacket.c.
5792 The code now assures that all data is read from the fd and then
5793 continues packet processing. This was a bug fix since the code
5794 used to drop some data in some circumstances.
5796 * Added new function into lib/silcclient/client.[ch]:
5797 silc_client_start_key_exchange to start key exchange after
5798 connection has been established to server. The code internally
5799 now uses this funtion but its main purpose was to provide it
5800 for applications that perform their own connecting. After
5801 application has created a connection it merely calls this
5802 function to start the key exchange between client and server.
5803 The library takes care of everything else after that.
5805 Updated also lib/silcclient/README to explain the usage of
5808 * Do not send to application information that connection has
5809 been established. Application gets notified it by connect
5812 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Applied cras's patch to add silc_schedule_one function. The
5815 function runs scheduler once and returns.
5817 * Fixed the scheduler after cras messed it up. The timeout
5818 handling works now as it's supposed to work.
5820 * Added into lib/silccore/ silcnotify.h to include notify
5821 message types support. Changed silc_server_send_notify*
5822 functions, in server.[ch], to support those new notify types.
5823 Added the support for the notify types into client library,
5824 as well. Added new notify client operation into ops.h in
5827 * Changed silc_server_packet_send_to_channel to send normal
5828 packets instead of just channel message packets. The function
5829 is now used to send the notify packets to channels. It is not
5830 used to send channel message packets anymore, as server never
5833 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5834 va_arg()s as it seems to require it nowadays. I guess, if SILC
5835 is compiled with older va_arg() the new code should work anyway.
5837 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Splitted core library. Core library (lib/silccore) includes
5840 now only SILC protocol specific core (and common) components.
5841 Created new utility library (lib/silcutil) that includes more
5842 generic purpose stuff. The stuff for util library was taken
5843 from the old core library. This was minor and easy split.
5845 * Created SILC Client Library (lib/silcclient) that includes
5846 implementation of the SILC client without user interface. This
5847 was major move from silc/ directory. The code has been changed
5848 so that it is transparent towards the user interface. The
5849 silc/ directory includes now the same user interface as before
5850 and it uses the new client library. Read lib/silcclient/README.
5851 Basicly, the client library performs everything else related
5852 to SILC except user interface handling. Also, configuration
5853 files are considered to be part of user interface and library
5854 does not handle them.
5856 This change also changed a lot of structures, function naming etc.
5857 Most important change was that SilcClientWindow object was
5858 renamed to SilcClientConnection in the client library. Created
5859 also new file lib/silcclient/ops.h. Also added new files
5860 silc/local_command.[ch] and silc/client_ops.[ch].
5862 All these changes were made to make it easier for user interface
5863 designers to create what ever user interface for the SILC client
5866 It is also expected that the server will be moved to lib
5867 directory as well and SILC Server Library will be created;
5868 sometimes in the future.
5870 * Removed Local commands from lib/silccore/silccommand.h as
5871 they are application specific and new client library does not
5872 handle any of those anymore.
5874 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5875 old client implementation in silc/.
5877 * Added support for callback functions in SILC_LOG_* macros.
5878 Application can now set its own callbacks that will be called
5879 instead of using the default functions that will always print
5880 the debug messages to stderr (or stdout). Also, debugging can
5881 now be disabled by setting silc_debug to FALSE and re-enabled by
5882 setting it to TRUE. Note, that logging will still work even
5883 if debugging is disabled.
5885 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5886 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5887 silc_log_reset_debug_callbacks.
5889 * To enable debugging in silc client one must give now -d
5890 option on command line.
5892 * Changed silc_schedule_init to automatically allocate task queues
5893 if they are not allocated before calling it.
5895 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Added GMP 3.1 into math library.
5899 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5902 a channel in SILC network. The packet is used by servers and
5903 routers to notify other routers that user has left a channel.
5904 This little feature was missing until now. Added the feature
5905 to protocol specification as well.
5907 Added functions: silc_server_send_remove_channel_user and
5908 silc_server_remove_channel_user into server.[ch].
5910 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5911 lib/silccore/silcpacket.h. However, they are not implemented
5914 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Fixed joining to a channel and sending channel messages
5917 between server and router. The channel message sending should
5918 now work inside a cell.
5920 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Fixed the private message sending between server and router.
5923 The private message sending should now work inside a cell.
5925 * Added silc_server_replace_id into server.[ch] to replace
5926 existing ID in the SILC network.
5928 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5929 and silc_idlist_replace_server_id into idlist.[ch] in server.
5931 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Fixed the server to server connections. Server can again now
5934 connect to router. Router to router connections probably does
5937 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added dynamic protocol registering support. Now protocols can
5940 registered and unregistered on the fly. Patch by cras.
5942 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Added lib/contrib directory to hold routines that some platforms
5945 don't have but are needed by SILC.
5947 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5948 into lin/contrib to provide getopt() and getopt_long() for
5949 those who don't have it.
5951 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Added AWAY command to client. When away message is set and
5954 client receives a private message packet the client automatically
5955 replies to the sender with the away message.
5957 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5958 bug seemed to be the cause of recent problems when compiling
5961 * Added version detection support to SKE protocol specification
5962 and added the new changes to the SKE implementation as well.
5963 There were other minor changes in the SKE protocol as well.
5965 Many changes in lib/silcske/silcske.[ch] and in
5966 lib/silcske/payload.[ch].
5968 * Added ^U functionality, clear input line. Patch from cras.
5970 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Mainly small bugfixes on core library. Fixed some debugging
5973 logging and buffer overflow in silclog.c.
5975 * Updated config.sub and config.guess on the distribution tree.
5977 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * Added command lagging support in server. Client may execute
5980 commands now only once in two seconds.
5982 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Optimized packet reception. MAC computation and checking is now
5985 also more optimized. A lot previously duplicated code is now
5986 used as generic by both client and server.
5988 * Fixed key pair generation in clientutil.c
5990 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Added into lib/silccore/silcbufutil.[ch] new function;
5993 silc_buffer_realloc.
5995 * Moved generic packet sending/encryption functions to
5996 lib/silccore/silcpacket.[ch] from client and server. Some
5997 rewriting of the functions.
5999 * Moved all generic packet reception/decryption functions to
6000 lib/silccore/silcpacket.[ch] from client and server. The
6001 packet processing is now much cleaner in both client and server.
6002 These were major changes in both client and server.
6004 * Created many common functions in server to do packet sending.
6005 Previously code were duplicated a lot, this has been removed
6008 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Rewrote major parts of the ID cache system. Don't know
6011 whether it is better now or not but at least the API is more
6014 * Major rewrite on ID cache stuff on client because of the ID
6015 cache API changes. Added idlist.c to client.
6017 * Also major rewrite on ID cache stuff on server as well.
6018 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6019 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6020 in hand, instead they are all put into the ID cache system now.
6021 All server_idlist_* routines uses ID cache now instead of
6022 traversing its own lists (those lists does not exist anymore).
6023 SilcIDList though still exists. Also, SilcXXXEntry's are
6026 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Finally made the SKE implementation compliant to the protocol
6029 specification. All mp integers are now binary encoded as
6030 opposed being HEX encoded.
6032 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6035 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6036 functions: silc_[encode/decode]_pem. Also added function
6037 silc_encode_pem_file to PEM encode with newlines ('\n') for
6040 * SILC public keys are now encoded either PEM or binary. Same
6041 option is for private keys as well. By default private keys
6042 are binary encoded and public keys PEM encoded. Silly HEX
6043 encoding were removed.
6045 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6046 function to create fingerprints.
6048 * Fixed a bug in SHA1; does not change the original data anymore.
6050 * Partly implemented INFO command on client and server side.
6051 Fixed CLEAR command. Changes to SERVER command; show current
6052 server(s) when giving command without arguments. Added
6053 VERSION command to client.
6055 * Added check to server that unregistered connections cannot
6056 execute commands (unless it is specificly allowed).
6058 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Fixed screen refresh.
6062 * Fixed channel joining bug from client. On some circumstances
6063 client tried to join to a channel it had already joined.
6065 * Added public key verification process into client's protocol.c.
6066 The client now verifies the public key from user and saves
6067 it into ~./silc/serverkeys/ directory.
6069 Added into: clientutil.[ch]: silc_client_verify_server_key.
6071 * Changed SKE protocol's silc_ske_initiator_finish function
6072 to accept callback function that verifies the received public
6073 key. Removed old silc_ske_verify_public_key function.
6075 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6078 silc_pkcs_private_key[_data]_set.
6080 * Made the password and public authentication more cleaner in
6081 server's protocol.c.
6083 * Removed historic and obsolete protocol `channel_auth' from
6084 both client and server.
6086 * Removed wrong way of sending command status messages from
6087 server to client in server's command.c. The old way violated
6088 protocol specification.
6090 Changes to silccore/silccommand.[ch]: removed
6091 silc_command_encode_status_payload -> not needed anymore,
6092 changed silc_command_encode_payload_va to accept extra
6093 argument on variable argument list. The argument type must
6094 now be provided to the function. Also, added new function:
6095 silc_command_encode_reply_payload_va which is same as
6096 normal command_encode_payload_va except command status type
6097 is provided as extra argument.
6099 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added ~./silc directory handling. The directory includes the
6102 public and private keys for the client.
6104 Added silc_client_check_silc_dir, silc_client_create_identifier
6105 and silc_client_load_keys.
6107 * Implemented SILC protocol compliant public key. Added public
6108 and private key saving to and loading from files.
6110 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6111 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6112 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6113 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6114 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6116 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6117 silc_pkcs_load_[public/private]_key.
6119 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Added silc_server_get_route (route.[ch]) to get connection
6122 data for the fastest route for given ID.
6124 * Implemented INVITE command on client and server. The command
6125 were re-defined in the SILC Protocol Specification and the
6126 implementation now complies with the specification.
6128 * Implemented PING command on client and server.
6130 * Implemented NAMES command on client and server. The server side
6131 supports currently only normal server not router server yet.
6132 Some changes to NAMES definition in SILC protocol specification.
6134 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Implemented LEAVE command on client and server.
6138 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6139 again. This change was made to the protocol as well. Server
6140 should not violate the protocol specification anymore.
6142 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6145 was tested. SOCKS4 was not but should work anyway.
