3 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
6 * Write PID file after dropping privileges. Added -F option
7 to run server on foreground. A patch by debolaz.
8 Affected files silcd/server.c, silcd/silcd.c.
10 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
12 * Fixed the silc_idcache_list_* routines to really support
13 the dynamic list. Fixes a crash. Affected file is
14 lib/silccore/silcidcache.c.
16 * Fixed the LIST command reply to really call LIST command's
17 pending callbacks. Affected file silcd/command_reply.c.
19 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Update conn->local_entry->nickname after giving NICK
22 command. Affected file lib/silcclient/command.c.
24 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
26 * Added the [pid] option to the silcd configuration file
28 Affected files: serverconfig.[ch] and silcd.c
30 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
32 * Save fingerprint in WHOIS command reply in server.
33 Affected file silcd/command_reply.c.
35 * Fixed NICK commands pending callback registration.
36 Affected file lib/silcclient/command.c.
38 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
40 * Use ++server->cmd_ident when sending commands in server,
41 instead of random number. Affected file silcd/command.c.
43 * Fixed GETKEY command reply to call actually GETKEY pending
44 command callbacks. Affected file silcd/command_reply.c.
46 * A bit stricter check for nicknames. Check for same nickname
47 in NICK command also. Affected file silcd/command.c.
49 * Do not call INFO command everytime client ID changes, only
50 during first connecting. Affected file lib/silcclient/client.c.
52 * Set the new nickname only after successful command reply for
53 NICK command is returned by server. Affected file
54 lib/silcclient/command.c.
56 * Remove nicknames from nicklist during server_signoff notify.
57 Should fix /NAMES bit more. The affected file is
58 irssi/src/silc/core/silc-channels.c.
60 * Added `fingerprint' field to the SilcIDListData in the
61 silcd/idlist.h to hold the fingerprint of the client's
64 Send the fingerprint of the client's public key in WHOIS
67 Affected files silcd/command.c, and silcd/idlist.[ch].
69 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
70 create fingerprint from given data.
72 * Show the fingerprint of the client's public key in WHOIS.
73 Affected files irssi/src/module-formats.[ch] and
74 irssi/src/silc/core/client_ops.c.
76 * Format the multiple same nicknames also during JOIN and
77 NICK_CHANGE notifys. Affected file is
78 lib/silcclient/client_notify.c.
80 * Do not print error on screen for invalid private message
81 payload since it can come if someone is sending private
82 messages with wrong key. Affected file
83 lib/silccore/silcprivate.c.
85 * Fixed multiple concurrent /PING crash. Affected file
86 lib/silcclient/command.c.
88 * Changed the wrong ID encoding. All IP addresses must be
89 in MSB first order in encoded format. They were encoded
90 wrong and was in LSB format. Affected files are
91 silcd/serverid.c, lib/silcutil/silcutil.c.
93 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
95 * Call the `connect' client operation through the scheduler
96 in case of error. Affected file lib/silcclient/client.c.
98 * Call the `failure' client operation even if the error
99 occurred locally during a protocol. Affected file is
100 lib/silcclient/protocol.c.
102 * Added support of sending LIST command to router from normal
103 server. This way normal server can get list of all channels
104 in the network too. Fixed the channel list sending in the
105 server too. Affected files are silcd/command.c, and
106 silcd/command_reply.[ch].
108 * Added silc_server_update_channels_by_server and
109 silc_server_remove_channels_by_server. They are used during
110 disconnection of primary router and in backup router protocol.
111 Affected file silcd/server_util.[ch], silcd/server.c and
112 silcd/server_backup.c.
114 * Fixed channel adding to global list in IDENTIFY command
115 reply in server. Affected file silcd/command_reply.c.
117 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
119 * If the incoming packet type is REKEY or REKEY_DONE process
120 that packet always synchronously. Fixes yet another MAC
121 failed error on slow (dialup) connections. Affected file
122 lib/silcclient/client.c and silcd/server.c.
124 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Call check_version SKE callback for initiator too. Affected
127 file lib/silcske/silcske.c.
129 * Implemented fix for security hole found in the SKE that was
130 fixed in the specification few days back; the initiator's
131 public key is now added to the HASH value computation.
132 Added backwards support for the old way of doing it too, for
133 old clients and old servers. Affected file is
134 lib/silcske/silcske.c.
136 * Enabled mutual authentication by default in SKE. If initiator
137 is not providing mutual authentication the responder will
138 force it. This will provide the proof of posession of the
139 private key for responder. The affected files are
140 lib/silcclient/protocol.c and silcd/protocol.c.
142 * Do not cache anymore the server's public key during SKE.
143 We do mutual authentication so the proof of posession of
144 private key is done, and if the server is authenticated in
145 conn auth protocol with public key we must have the public
146 key already. Affected file silcd/protocol.c.
148 * Added new global debug variable: silc_debug_hexdump. If
149 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
150 file lib/silcutil/silclog.[ch].
152 * Fixed compilation warning due to char * -> const char *.
153 Affected files lib/silcutil/silcnet.h, and
154 lib/silccore/silcauth.[ch].
156 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
158 * Fixed CMODE command when new channel key was created. If
159 the creation failed the old key was removed. Next time giving
160 same command would crash the server since the old key was
161 freed already. Affected file silcd/command.c.
163 * Fixed the silc_server_announce_get_channels to not crash
164 on reconnect. Affected file silcd/server.c.
166 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
168 * Added silc_log_set_debug_string function to set a regex
169 string to match for debug output. Only the function names,
170 or filenames matching the given debug string is actually
171 printed. This way it is possible to filter out those debug
172 strings that user is not interested in.
174 Fixed a bug in silc_string_regexify.
176 Affected files lib/silcutil/silclog.[ch], and
177 lib/silcutil/unix/silcunixutil.c.
179 * Changed the -d options in both server and Irssi SILC client
180 to take the debug string as argument. Affected files
181 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
183 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
185 * Added silc_hash_babbleprint to create a Bubble Babble
186 Encoded fingerprint. The encoding is developed by Antti
187 Huima (draft-huima-babble-01.txt), and it creates human
188 readable strings out of binary data. Affected file
189 lib/silccrypt/silchash.[ch].
191 * Print the babble print now in addition of fingerprint as well
192 in Irssi SILC client. Affected files are
193 irssi/src/fe-common/silc/module-formats.[ch],
194 irssi/src/fe-common/silc/core/client_ops.c.
196 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
198 * Fixed a security problem found in SKE. The initiator's
199 public key too is now added to the HASH hash value creation
200 which is signed by the responder to create the SIGN value.
201 This will prevent anyone in the middle to lie to the responder
202 about the initiator's public key. If this is done now, the
203 man in the middle will get caught. Updated the protocol
206 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
208 * Better installation directory handling. Configure module
209 paths and other paths automatically to example_silc* files
210 in doc/. A patch by toma.
212 * Fixed compiler warning from MPI library, and from SILC RNG.
215 * Added SILC_SERVER_PID_FILE to define the pid file for server.
216 It can be configured with ./configure. A patch by toma.
218 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
220 * Find correct make to use in prepare-clean. A patch by
221 toma. Affected file prepare-clean.
223 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
225 * Added irssi variables use_auto_addr, auto_bind_ip,
226 auto_bind_port and auto_public_ip.
228 * Changed the interface for silc_client_send_key_agreement
229 in lib/silcclient/silcapi.h
233 irssi/src/silc/core/silc-core.c
235 lib/silcclient/silcapi.h
236 irssi/src/silc/core/silc-channels.c
237 lib/silcclient/client_keyagr.c
240 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
242 * Added silc_pkcs_public_key_compare to compare two
243 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
245 * Check that the client who set the founder mode on the
246 channel is the same client that is giving the founder
247 mode to itself. It is done by comparing the saved public
248 key (it is saved even in the authentication is passphrase).
249 Affected file silcd/command.c.
251 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
253 * Do not process packet for disconnected socket connection.
254 Affected file lib/silccore/silcpacket.c.
256 * Process the DISCONNECT packet through scheduler in the
257 client library. Affected file lib/silcclient/client.c.
259 * Fixed the silc_client_packet_parse to not to increase
260 the packet sequence number if the conn->sock and the
261 current socket connection is not same. This can happen
262 for example during key agreement when the conn includes
263 multiple socket connections (listeners). Affected file
264 lib/silcclient/client.c.
266 * The sender of the file transfer request now provides also
267 the pointer (listener) for the key exchange protocol. If
268 the listener cannot be created then it sends empty key
269 agreement and lets the receiver provide the listener.
271 Added `local_ip' and `local_port' arguments to the
272 silc_client_file_send. If they are provided they are used,
273 if not then it will attempt to find local IP address, if
274 not found or bind fails then the remote client will provide
277 Affected files are lib/silcclient/client_ftp.c and
278 lib/silcclient/silcapi.h.
280 * Extended the FILE SEND command to support defining the
281 local IP and port for key exchange listener. They are
282 optional. Affected file irssi/src/silc/core/silc-servers.c.
284 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
286 * Defined to WHOIS command reply the sending of fingerprint
287 of the client's public key (if the proof of posession of the
288 corresponding private key is verified by the server).
289 Updated to the protocol specification.
291 * Added support of receiving the client's public key's
292 fingerprint in command reply in client library. Affected
293 file is lib/silcclient/command_reply.c, and
294 lib/silcclient/idlist.[ch].
296 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
298 * Do not send over 128 chars long nickname to the server
299 in NICK command. Affected file lib/silcclient/command.c.

302 in JOIN command. Affected file lib/silcclient/command.c.
304 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
306 * Assure that silc_server_close_connection cannot be called
307 twice for same socket context. Affected file is
310 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Send error message to application if opening file for
313 writing during file transfer fails. Affected file is
314 lib/silcclient/client_ftp.c.
316 Remove all file transfer sessions for a client that we're
317 removing from ID cache.
319 Affected file is lib/silcclient/client_ftp.c.
321 * Fixed silc_net_addr2bin to return correct address. Affected
322 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
324 * Fixed file transfer session removing on signoff notify.
325 Affected file irssi/src/silc/core/silc-servers.c.
327 * Added the SilcClientFileError to be returned in the monitor
328 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
329 Affected file lib/silcclient/silcapi.h.
331 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
333 * Fixed a crash in silc_client_ftp_free_sessions and
334 silc_client_ftp_session_free_client. Affected file
335 lib/silcclient/client_ftp.c.

338 to indicate if the server entry is disabled. Affected file
339 silcd/idlist.h, silcd/command[_reply].c.
341 * SILC server adds now /var/run/silcd.pid everytime it is
342 started. Affected file silcd/silcd.c.
344 * Added silc_server_packet_send_clients to send a packet to
345 the provided table of client entries. Affected file
346 silcd/packet_send.[ch].
348 * Fixed a crash in client resolving in client_prvmsg.c in
349 client library. Affected file lib/silcclient/client_prvmsg.c.
351 * Do not actually remove the client directly from ID cache
352 during SERVER_SIGNOFF, but invalidate it. This way we
353 preserve the WHOWAS info for the client. Affected file
356 * Fixed SERVER_SIGNOFF notify handling in the server. The
357 server is now able to process incoming SERVER_SIGNOFF notify
358 for a server that it doesn't even know about. It will remove
359 the clients provided in the notify. Affected file
360 silcd/packet_receive.c.
362 * Check for partial packet in data queue after every packet that
363 was found from the queue. Return and wait for more data if
364 there is partial data in queue. Affected file is
365 lib/silccore/silcpacket.c.
367 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Added SilcClietFileError enum to indicate error in
370 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
371 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
372 Affected files lib/silcclient/silcapi.h and
373 lib/silcclient/client_ftp.c.
375 * Check that newsize in silc_buffer_realloc is larger than
376 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
378 * Added better monitor of file transfers. It now monitors
379 key agreement protocol during the file transfer too. Added
380 error reporting too. Affected files
381 irssi/src/silc/core/silc-servers.c,
382 irssi/src/fe-common/silc/module-formats.[ch].
384 * Wrote a help file for FILE command.
386 * Added silc_rng_global_get_byte_fast to get not-so-secure
387 random data as fast as possible. Random data is read from
388 /dev/urandom if available and from the SILC RNG if not
389 available. It is used in padding generation. Affected file
390 lib/silccrypt/silcrng.[ch].
392 * All packets in client library are now processed synchronously.
393 Optimized packet processing a lot. Affected file
394 lib/silcclient/client.c.
396 * All server connection packets are processing synchronously
397 now in server, to optimize packet processing. Affected file
400 * Include files are installed now only in Toolkit distribution
401 if make install is given. Affected files: all Makefile.am's.
403 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Assure that silc_client_notify_by_server_resolve does not
406 resolve the client information multiple times. If it cannot
407 be found by the first it cannot be found at all. Affected
408 file lib/silcclient/client_notify.c.
410 * Fixed WHOWAS command reply calling. Affected file
411 lib/silcclient/command_reply.c.
413 * Removed all references to silc_idlist_get_client from the
414 Irssi SILC client since that call is internal call used by
415 the library. The Irssi SILC client will use now client
416 retrieval functions found in silcapi.h.
418 * Fixed a bug in resolving nickname info before sending
419 private message. It used freed memory. Affected file
420 irssi/src/silc/core/silc-servers.c.
422 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
424 * Assure my_channels statistics cannot go negative in server.
425 Affected files silcd/server.c, silcd/server_util.c.
427 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
431 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
433 * Win32 Toolkit changes. Affected files
434 win32/silc.dsw, win32/libsilc/libsilc.def,
435 win32/libsilcclient/libsilc.def,

441 * Added silc_net_localip to return local host's IP address.
442 Affected file lib/silcutil/silcnet.[ch].
444 * If key exchange or rekey protocol is active for a connection
445 parse all packets syncronously since there might be packets
446 in packet queue that we are not able to process without first
447 processing packets before them. Affected file silcd/server,
448 lib/silcclient/client.c.
450 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
451 whether library should continue processing the packet.
452 Affected file lib/silccore/silcpacket.h.
454 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
455 SilcSFTPMonitorData to SFTP server to monitor various
456 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

459 * Added silc_file_size to return file size. Affected file
460 lib/silcutil/silcutil.[ch].
462 * Implemented the file transfer support for the client library.
463 Added preliminary support for simple client to client one-file
464 transmission. Affected file lib/silcclient/client_ftp.c,
465 lib/silccilent/client.[ch].
467 * Added new local command FILE to the Irssi SILC Client.
468 It is used to perform the file transfer. It has subcommands
469 SEND, RECEIVE, SHOW and CLOSE. Affected files
470 irssi/src/silc/core/client_ops.c,
471 irssi/src/silc/core/silc-server.[ch].
473 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
475 * Relay the SILC_PACKET_FTP in the server. Affected files
476 silcd/server.c and silcd/packet_receive.c.
478 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
480 * Renamed silc_file_read and silc_file_write to functions
481 silc_file_readfile and silc_file_writefile. Added function
482 silc_file_open and silc_file_close. Affected files
483 lib/silcutil/silcutil.[ch].
485 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
487 * Resolve the client info when received private message or
488 channel message for a client which nickname we don't know.
489 Affected files lib/silcclient/client_prvmsg.c and
490 lib/silcclient/client_channel.c.
492 * Do not crash in /KEY if client is not connected. Affected
493 file irssi/src/silc/core/silc-channels.c.
495 * Added SilcClientStatus field to the SilcClientEntry in the
496 lib/silcclient/idlist.h.
498 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
499 is incomplete and is being resolved, it won't be resolved
502 Make sure also that USERS command reply does not resolve
503 twice information. Affected file is
504 lib/silcclient/command_reply.c.
506 Make sure that silc_client_get_clients_by_list does not
507 resolve twice same information.
509 * Check for valid client->id in the silc_server_free_client_data.
510 Affected file silcd/server.c.
512 * Fixed /GETKEY nick@server not to crash if the server entry
513 is not found. Affected file lib/silcclient/command.c.
515 * Fixed the silc_server_check_cmode_rights to check the
516 requested modes correctly. Affected file silcd/command.c.
518 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
520 * Better checks for non-printable chars in nick added.
521 Affected file silcd/command.c.
523 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Call the silc_server_udpate_servers_by_server in the
526 primary router that comes back online in the backup resuming
527 protocol. Otherwise it routes packets wrong. Affected file
528 silcd/server_util.[ch], silcd/server_backup.c.
530 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
532 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
533 lib/silcutil/silcbuffmt.[ch].
535 * Redefined the SILC packet header to include the padding
536 length. Affected file lib/silccore/silcpacket.[ch].
538 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
539 length for maximum padding up to 128 bytes). Affected
540 file lib/silccore/silcpacket.h.
542 * Removed all backwards support for old 0.5.x MAC thingies.
543 The SILC packet header change makes it impossible to be
544 backwards compatible.
546 * Send the ENDING packet with timeout in the backup resuming
547 protocol. This is to assure that all routers has connected
548 to the primary router. Affected file silcd/server_backup.c.
550 * Changed the RNG to take the first IV from random data. It
551 used to take it from zero actually. Changed the RNG also
552 to use /dev/urandom during session. /dev/random is used
553 in initialization. Affected file lib/silccrypt/silcrng.[ch].
555 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
557 * Changed the SILC packet header to have the first two bytes
558 (the packet length) encrypted. Affected files aroung the
559 code tree, lib/silccore/silcpacket.[ch]. Removed the
560 SilcPacketCheckDecrypt callback. It is not needed anymore
561 since the silc_packet_receive_process will determine now
562 whether the packet is normal or special.
564 * Implemented the unidirectional MAC keys. Affected files
565 lib/silcske/silcske.c, silcd/protocol.c and
566 lib/silcclient/protocol.c.
568 * Implemented the packet sequence number to the MAC computation.
569 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
570 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
571 lib/silcclient/protocol.c.
573 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
575 * Allow backup router to announce servers. All servers
576 announced by backup router are added to the global list
577 automatically. Update hte server's socket to our primary
578 router also when backup router announces a server.
579 Affected file silcd/packet_receive.c.
581 * Do not update the client->router in the function
582 silc_server_udpate_clients_by_server if the client is on
583 global list. We might fail to find any specific server
584 for locally connected clients and local cell clients. They
585 should still use the `from' and not `to' as client->router.
586 This fixes backup router resuming protocol. Affected file
589 * Decrease channel statistics count only if the channel
590 deletion worked. Affected files are silcd/server.c and
593 * Added silc_server_update_servers_by_server to update origin
594 of all server entries. Used during backup router protocol.
595 Affected files silcd/server_util.[ch], silcd/server.c. and
596 silcd/backup_router.c.
598 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
599 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
600 silc_hmac_get_hash and silc_hmac_get_name. Affected file
601 lib/silccrypt/silchmac.c.
603 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
605 * Assure that router cannot reroute the same channel message
606 to the sender. Affected file silcd/packet_receive.c.
608 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Made better checks that the channel message is not sent
611 to the router it came from. Affected file is
612 silcd/packet_send.c. Fixed memory leak too.
614 * Announce informations for incoming router connection, but
615 only after checking if it is replaced by backup router.
616 Affected file silcd/packet_receive.c.
618 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Fixed the backup resuming protocol to work in multiple
621 router environment. Affected file silcd/server_backup.c.
623 * Route packet only to one router in the function
624 silc_server_packet_send_to_channel. Affected file is
627 * Fixed silc_server_send_notify_dest to set the broadcast
628 flag. Fixed the silc_server_send_notify_topic to actually
629 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
630 Affected file silcd/packet_send.c.
632 * Changed the SFTP Filesystem interface. Changed the
633 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
634 the filesystem operation function. The SilcSFTPFilesystem
635 is now a context that is allocated by all filesystem allocation
636 functions and it already includes the operations structure
637 and filesystem specific context. It is given as argument
638 now to the silc_sftp_server_start. This made the interface
639 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
640 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
642 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Changed the backup router adding and getting interfaces
645 in the server. The router that will be replaced by the
646 specified backup router is now sent as argument. Affected
647 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
650 * Added silc_net_addr2bin_ne to return the binary form of
651 the IP address in network byte order. Affected files
652 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
654 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Check for existing server ID in silc_server_new_server
657 and in silc_server_connect_to_router_final and remove the
658 old entry if it exists. Affected file silcd/packet_receive.c,
661 * Send the channel message always to only one router, either
662 in upstream or downstream. Affected file is
665 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Wrote the definition of the backup resuming protocol to the
668 protocol specification.
670 * Removed one redundant channel key generation from normal
671 server during joining procedure. Removed one redundant
672 channel key sending from server to router during joining
673 procedure. Affected file silcd/command.c.
675 * Made minor bugfixes to the backup router resuming protocol.
676 Affected file silcd/server_backup.c, server.c.
678 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Added --disable-asm configuration option. Affected files
681 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
684 * Implemented the backup resuming protocol that is used to
685 resume the primary router position in the cell after the
686 primary router comes back online. Affected files
687 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
688 and silcd/server_util.[ch].
690 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Sleep two (2) seconds after sending QUIT command to server.
693 Affected file lib/silcclient/command.c.
695 * Assure that if outgoing data buffer is pending do not force
696 send any data. Affected file silcd/packet_send.c.
698 * Assure that if outgoing data buffer is pending do not force
699 send any data. Affected file lib/silcclient/client.c.
701 * Implemented the backup router support when the primary router
702 goes down. The servers and routers can now use the backup
703 router as new primary router without loosing connectivity.
705 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
707 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
708 in the server to indicate disabled entry. All data read
709 from the connection will be ignored and no data is sent
710 for entry that is disabled. Affected files are
711 silcd/idlist.h, silcd/server.c.
713 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Created SFTP client and server test programs in the
716 lib/silcsftp/tests directory.
718 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Implemented memory filesystem (virtual filesystem) for
721 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
724 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Implemented the SFTP (SSH File Transfer Protocol) to the
727 lib/silcsftp. It includes SFTP client and SFTP server
730 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Moved lib/silccore/silcprotocol.[ch] to the
733 lib/silcutil library.
735 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
736 take variable argument list pointer as argument. Affected
737 file lib/silcutil/silcbuffmt.[ch].
739 * Added silc_buffer_set function that is used to set data
740 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
741 Affected file lib/silcutil/silcbuffer.h.
743 * Changed various routines in the core library to use the new
744 silc_buffer_set instead of allocating new buffer only for
747 * Added 64-bit value formatting and unformatting support to the
748 silc_buffer_[un]format routines. Affected file is
749 lib/silcutil/silcbuffmt.[ch].
751 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
752 to includes/bitmove.h.
754 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Fixed channel user mode saving in client library. Affected
757 file lib/silcclient/command[_reply].c.
759 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
761 * Defined the file transfer to the SILC Protocol. Added
762 new packet type SILC_PACKET_FTP and defined File Transfer
763 Payload. The mandatory file transfer protocol is SFTP
764 (SSH File Transfer Protocol). Affected file in addition
765 of the internet draft is lib/silccore/silcpacket.h.
767 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
768 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
769 is used as part of backup router protocol when the primary
770 router of the cell is back online and wishes to resume
771 the position as primary router.
773 * Redefined the MAC generation keys in the protocol. The
774 same key is not used anymore in both direction. Both
775 direction will now use different keys for sending and
776 receiving. This fixes a potential security flaw. This
777 change causes incompatibilities in the protocol.
779 * Redefined also the MAC computation from the packet.
780 An packet sequence number is now added to the MAC
781 computation. This prevents possible replay attacks against
782 the protocol. This change too causes incompatibilities
785 Added `sequence' field to the SilcPacketContext to hold
786 the current sequence number for the packet.
788 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Added `created' field to the SilcIDListData in the file
791 silcd/idlist.h to indicate the time when the entry was
794 * Added `created' field to the SilcChannelEntry too. Affected
797 * Added `creation_time' aguments to all the announcement functions
798 in the server. If it is provided then only the entries that
799 was created after the provided time frame are actually
800 announced. Affected file silcd/server.[ch].
802 * The protocol says that the Channel ID's IP address must be
803 based on the router's IP address. Added check for this in
804 the silc_server_new_channel when processing incoming New Channel
805 Payload. Affected file silcd/packet_receive.c.
807 * Print out the correct version with --version in SILC client.
808 Affected file irssi/src/silc/core/silc-core.c.
810 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Fixed WHOWAS command to check for completnes of the client
813 entry always, not just when the command is coming from client.
814 Affected file silcd/command.c.
816 * Added new function silc_server_packet_queue_purge to purge the
817 outgoing data queue to the network. After the function returns
818 it is guaranteed that the outgoing packet queue is empty.
819 Affected file silcd/packet_send.[ch].
821 * Purge the outgoing packet queue in the rekey protocol's final
822 callback to assure that all rekey packets go to the network
823 before quitting the protocol. Affected file silcd/server.c.
825 * Added silc_client_packet_queue_parse as similar function as
826 in server to the client library. The affected file is
827 lib/silcclient/client.c.
829 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Splitted silcd/server.c and created silcd/server_util.[ch]
832 for utility functions.
834 * Added new socket flag SILC_SF_DISABLED to indicate that the
835 connection is open but nothing can be sent to or received from
836 the connection. Affected file lib/silcutil/silsockconn.[ch].
837 The checking for disabled socket is checked in the low level
838 silc_socket_write and silc_socket_read functions.
840 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
842 * Allow only nicknames and channel names that fits into the
843 7-bit unsigned char ASCII set. Affected file silcd/command.c.
845 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
847 * When processing JOIN command reply in server check that if
848 the channel exists in our global list we'll move it the local
849 list. Affected file silcd/command_reply.c.
851 * Fixed the check whether client is joined on the channel already
852 in JOIN command. Affected file lib/silcclient/command.c.
854 * Fixed the JOIN command reply to check whether the channel
855 already exists. Affected file lib/silcclient/command_reply.c.
857 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Added silc_ske_status_string to map the SKE error numbers
860 to readable strings. The affected files are
861 lib/silcske/silcske[_status].[ch].
863 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Do not show the private channels on the WHOIS channel list
866 as it is not allowed by the protocol. The affected file is
869 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Assure that the packet length digged from the actual packet
872 is something sensible in the silc_packet_decrypt_rest_special
873 in lib/silccrypt/silcpacket.c.
875 * Free and NULL the allocated pointer in silc_hmac_alloc if
876 the HMAC allocation fails. The affected file is
877 lib/silccrypt/silchmac.c.
879 * Print the selected security properties to the log files in
880 the server. Affected file silcd/protocol.c.
882 * Add SKE's reference counter even if calling the completion
883 callback manually. Otherwise it goes negative, although it
884 does not cause any problems. The affected file is
885 lib/silcske/silcske.c.
887 * Remove the client entry with short timeout after giving the
888 KILL command. Affected file lib/silcclient/command.c.
890 * Fixed to send error reply in WHOIS and IDENTIFY commands in
891 case all found clients are already disconnected (WHOWAS would
892 found them) in the server. Affected file silcd/command.c.
894 * Update the last_receive (time of last data received) to be
895 updated only when received private or channel message so that
896 the idle time showed in WHOIS makes more sense.
898 * Added boolean field `valid' in to the SilcClientEntry in the
899 client library to indicate whether the entry is valid or not.
900 This fixes the nickname change bug on channel when changing
901 the nickname to be same than the old (like nick to Nick) the
902 nickname formatter doesn't set the new nick anymore to Nick@host.
903 Affected file lib/silcclient/idlist.[ch].
905 * Now actually fixed the nickname changing on disconnection.
906 Added new function silc_change_nick to the Irssi SILC Client.
907 Affected file irssi/src/silc/core/client_ops.c,
908 irssi/src/silc/core/silc-nicklist.[ch].
910 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Check that the public key exists in the GETKEY command before
913 trying to encode it. Affected file silcd/command.c.
915 * Print some notifications on received public keys with GETKEY
916 command in the Irssi SILC Client. Affected files are
917 irssi/src/fe-common/silc/module-formats.[ch],
918 irssi/src/silc/core/client_ops.c.
920 * Use IDENTIFY command to resolve the server information in the
921 GETKEY command instead of INFO command. Affected file
922 lib/silcclient/command.c.
924 * All command reply functions in the client library now calls
925 the pending command reply callbacks even if an error has
926 occurred. The server has done this a long time and now it was
927 time to move the client library to this as well. Now all
928 errors can be delivered back to the pending command reply
929 callbacks if necessary. Affected files are
930 lib/silcclient/command[_reply].[ch].
932 * Change the nickname on disconnection back to the username
933 because in reconnect the server will enforce it to it anyway.
934 Affected file irssi/src/silc/core/silc-servers.c.
936 * Fixed a config file parsing bug in the Irssi SILC client.
937 Affected file irssi/src/silc/core/clientconfig.c.
939 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
941 * When printing the channel mode on JOIN, verify that the
942 channel key and channel's HMAC are valid. Affected file
943 irssi/src/silc/core/client_ops.c.
945 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
947 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
948 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
949 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
951 * Removed channel key rekey task deleting from the function
952 silc_server_save_channel_key. Affected file silcd/server.c.
953 Added explicit timeout task context instead that is used to
954 delete the task if we are registering a new task before the
955 new task has elapsed.
957 * When channel key rekey occurs the client library now saves
958 the old channel key for a short period of time (10 seconds) and
959 is able to use it in case some is still sending channel
960 messages encrypted with the old key after the rekey. Affected
961 file lib/silcclient/[idlist.h|client_channel.c].
963 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
965 * Added check to the silc_server_new_id_real to not accept
966 new ID if it is the sender's own ID. Affected file is
967 silcd/packet_receive.c.
969 * Assure that we do not announce ourself or the one we've
970 sending our announcements when we're router and are announcing
971 servers to our primary router. Affected file silcd/server.c.
973 * Fixed silc_server_command_identify_check_client to assemble
974 correct WHOIS packet. It send corrupted WHOIS packet and
975 caused problem with router to router connections. Affected
976 file silcd/command.c.
978 Fixed also silc_server_command_whois_check the same way
979 as for the IDENTIFY command.
981 * Added new SilcIDListStatus to the server in the SilcIDListData
982 structure. The status now includes the current status of
983 the entry (like registered, resolved etc.). Affected file
984 silcd/idlist.[ch]. Defined a bunch of different status types
985 as well. This replaced the old boolean registered field as well.
987 Added resolve_cmd_ident field to the SilcClientEntry structure
988 too so that if the entry is for example being resolved so
989 another command may attach to the same pending command reply
990 without requiring to resolve the same entry again. This concept
991 should optimize the WHOIS and the IDENTIFY resolving under
992 heavy load by taking away unnecessary resolving for entries
993 that are being resolved already.
995 Added support for adding multiple pending commands for one
996 command idenfier. Affected file silcd/command[_reply].[ch].
998 * Fixed WHOIS and IDENTIFY save to remove the cache entry
999 before deleting the data. Otherwise the hash table will have
1000 freed data in comparison functions. Affected file is
1001 silcd/command_reply.c.
1003 * Fixed silc_idlist_replace_client_id to add the new entry to
1004 the cache with NULL nickname. Otherwise there will be invalid
1005 memory as the nickname after the nickname is freed. Affected
1006 file silcd/packet_receive.c.
1008 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1009 saved into wrong slots because the previous number of entries
1010 was not taken into account. Affected file silcd/idlist.c.
1011 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1013 * If we are router and we receive JOIN notify to a channel that
1014 does not have any users then notified client is marked as the
1015 channel founder, as it is it. The affected file is
1016 silcd/packet_receive.c
1018 * Added to the extended hash table API's table_del_*ext functions
1019 the destructor as argument too, so that the caller can decide
1020 which destructor to use or whether to use destructor at all.
1021 Affected file lib/silcutil/silchashtable.[ch].
1023 * Fixed ID Cache purging. It actually deleted the entries from
1024 the hash table after the data was freed. The hash table ended
1025 up comparing freed memory. The affected file is
1026 lib/silccore/silcidcache.c.
1028 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Fixed Irssi SILC client's KILL command's HELP syntax.
1032 * The USERS command now resolves the detailed user information
1033 if the userinfo field is missing. Affected file is
1034 lib/silcclient/command_reply.c.
1036 * Do not print error in silc_file_read if the read file does
1037 not exist. Just silently return NULL. Affected file is
1038 lib/silcutil/silcutil.c.
1040 * Fixed the silc_log_output to not wine about NULL filename
1041 and to not create some bogus " " filename. Affected file is
1042 lib/silcutil/silclog.c.
1044 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * Fixed various printing bugs on the user interface in the
1047 Irssi SILC Client. Minor changes that were forgotten from
1050 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Fixed the configure.in.pre and the compilation and distribution
1053 environment to support the new autoconf 2.52. That version is
1054 now required to compile the CVS trunk.
1056 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1059 to generally parse user@fqdn format strings. Affected file
1060 lib/silcutil/silcutil.c.
1062 * Added nickname_format and nickname_force_format fields to the
1063 SilcClientParams structure. The first one defines the format
1064 for the nicknames that the library will enforce if the receives
1065 multiple same nicknames. The second one is boolean value and
1066 can be used to force the library to always enforce the format
1067 to the nicknames regardles whether there are multiple nicknames
1068 or not. This configurable formatting was employed to flexibly
1069 support accessing multiple nicknames from the user interface.
1070 The userinterface can now set the nicknames to what ever format
1071 they prefer. Affected file lib/silcclient/silcapi.h.
1073 Added function silc_client_nickname_format to the file
1074 lib/silcclient/idlist.c. It performs the nickname formatting.
1076 Added new field `hostname´ to the SilcClientEntry context.
1077 It holds the hostname of the client. Affected file is
1078 lib/silcclient/idlist.h.
1080 * Irssi SILC Client sets the nicknames in nick@hostn format.
1081 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1082 irssi/src/silc/core/silc-core.c.
1084 The WHOIS printing now also shows both the real nickname and
1085 the formatted nickname so that user knows how to access the
1086 user if there are multiple same nicknames cached. Affected
1087 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1088 printing formatting too to take the hostname now as a separate
1089 argument. The Affected file is
1090 irssi/src/fe-common/silc/modules-formats.[ch].
1092 * Changed the silc_client_get_clients_local to accept the formatted
1093 nickname as argument. It accepts the real nickname too but the
1094 formatted nickname can be used to find the true entry from
1095 multiple entries. Affected file lib/silcclient/silcapi.h and
1096 lib/silcclient/idlist.c.
1098 * Added nickname_format_parse field to the SilcClientParams.
1099 It is a callback function provided by the application to parse
1100 the nickname out of the formatted nickname string. The library
1101 calls it to get the nickname from the formatted string. Since
1102 the application generally knows better the format of the nickname
1103 string it parses it instead of the library, even though library
1104 encodes the formatted string. If the callback function is not
1105 provided then the library will use the string as is. The
1106 affected file is lib/silcclient/silcapi.h.
1108 * All the nickname strings passed to the client library in
1109 commands are now expected to be formatted nickname strings.
1110 If the command does not support the formatted nickname string
1111 it will assume that the sent string is the actual nickname.
1112 Affected file lib/silcclient/command.c.
1114 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Added public key authentication support to OPER and SILCOPER
1117 commands in the client library. Affected file is
1118 lib/silcclient/command.c.
1120 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Changed the get_auth_methdod client operation to be asynchronous.
1123 It can be async if the application resolves the authentication
1124 method from the server during the negotiation. Added new
1125 SilcGetAuthMeth completion callback that the application will
1126 call after resolving the authentication method.
1128 Added function silc_client_request_authentication_method that
1129 the application can use to resolve the authentication method
1130 from the server. Added also SilcConnectionAuthRequest callback
1131 that the library will call after the server has replied. The
1132 application can call this function if it does not know the
1133 current authentication method.
1135 Affected files are lib/silcclient/client.c and
1136 lib/silcclient/silcapi.h.
1138 * The Irssi SILC client now automatically resolves the authentication
1139 method incase any configuration information is not present (and
1140 currently there never is). The affected file is
1141 irssi/src/silc/core/client_ops.c.
1143 * Fixed public key authentication from the client library.
1144 Affected file lib/silcclient/protocol.c. Changed also the
1145 protocol specification about the public key authentication in
1146 the connection authentication protocol. The actual data to be
1147 signed is now computed with a hash function before signing.
1149 * Fixed the public key authentication from the server as well.
1150 Affected file silcd/protocol.c.
1152 * Removed the mlock()'s from the memory allocation routines.
1153 Affected file lib/silcutil/silcmemory.c. The ./configure does
1154 not check anymore for the mlock(). Affected file is
1157 * Fixed USERS command in server to allow the execution of the
1158 command for private and secret channels if the client sending
1159 the command is on the channel. Affected file silcd/command.c.
1161 * Fixed silc_client_get_clients_local to return the clients
1162 count correctly. It could return wrong value. Affected file
1163 lib/silcclient/idlist.c.
1165 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1168 types. The assembler optimizations seemed not to like 64-bit
1169 data types. The assmebler optimizations thus are now enabled
1170 also for BSD systems as opposed to only enable them for Linux.
1172 * Do not check for threads at all on BSD systems. Affected
1173 file configure.in.pre.
1175 * Removed -n and -h options from the Irssi SILC Client since
1176 they are not used in silc.
1178 * Fixed the prime generation to assure that the first digit
1179 of the generated random number is not zero since our conversion
1180 routines does not like number strings that starts with zero
1181 digit. If zero digit is seen the random number is regenerated.
1182 This caused some corrupted RSA keys when the zero first digit
1183 was met. Affected file lib/silcmath/silcprimegen.c.
1185 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Fixed WIN32 configuration in the ./configure script.
1188 Fixed to include xti.h on environments that has it.
1189 Patches by Carsten Ilchmann and andrew.
1191 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Changed the silc_id_create_client_id to be collision
1194 resistant. It is now assured that there cannot be created
1195 two same client ID's. I suspect that some weird bugs in
1196 the server were actually caused by duplicate Client IDs.
1197 Affected file silcd/serverid.[ch]. A router receiving
1198 new ID now also assures and informs the sending server
1199 if the ID caused collision.
1201 * Changed the silc_id_create_channel_id to also assure that
1202 there are no collisions.
1204 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Statement about ignoring the Mutual Authentication flag when
1207 performing rekey with PFS was a bit misleading. It is ignored
1208 if it was set in the initial negotiation, it cannot be even
1209 set in the rekey. Fixed in the ke-auth draft. Started the
1210 new versions of the protocol drafts in the doc/.
1212 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1214 * Fixed a bug in silc_client_command_identify_save when saving
1215 new channel information. The channel name was no duplicated
1216 and caused crash on exit. Affected file is
1217 lib/silcclient/command_reply.c.
1219 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1221 * Fixed the getkey command handling in the server. Send just
1222 empty OK reply to the sender if the key could not be fetched
1223 (but everything else was ok, like the key just was not available).
1224 Changed the public key parameter to optional in the protocol
1225 specs so that empty OK reply can be sent. Affected file
1228 Added a message to Irssi SILC client to tell to user if the
1229 server did not return a public key.
1231 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Fixed a channel key regeneration bug. It registered new
1234 timeout tasks exponentially until all system resources were
1235 used. Affected file silcd/server.c.
1237 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Added the SILC Document generator to the scripts/silcdoc.
1240 It can be used to generate the Toolkit Reference Manual out
1241 of the source tree. Internally it will also use the RoboDoc
1242 generator now imported in util/robodoc.
1244 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Added couple of return's in rekey protocol if error orccurred
1247 during the protocol. The execution must be terminated.
1248 Affected file silcd/protocol.c. Also, terminate the protocol
1249 always with timeout.
1251 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * The client's Client ID was created initally from the wrong
1254 nickname (it could have been in format nick@host) in the
1255 silc_server_new_client. Affected file silcd/packet_receive.c
1257 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Added some SILC_LOG_ERROR's to various error conditions
1260 if client could not be added to ID cache. Affected files
1261 silcd/packet_receive.c and silcd/server.c.
1263 * When client's sock->user_data is freed, NULL also the
1264 client->router and client->connection pointers. Added check
1265 for these pointers being NULL to various places around the
1266 code. Affected file silcd/server.c.
1268 * Added client->data.registered == TRUE checks to various
1269 places around the code to assure that unregistered client's
1270 are not handled when it is not allowed. Affected file
1273 * Added `bool registered' fields to all
1274 silc_idlist_[server|client]_get_* routines to indicate whether
1275 the fetched client needs to be registered or not. Affected
1276 file silcd/idlist.[ch].
1278 * Add your own entry as registered to the ID cache in the
1279 server. Affected file server.c.
1281 * Fixed a bug in silc_server_new_server. The SilcServer was
1282 set as the new server's context instead of SilcServerEntry.
1283 This naturally caused some weird bugs.
1285 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Do not delete the channel rekey task when adding it
1288 for in silc_server_create_channel_key.
1290 * Changed the silc_server_create_channel_key to return
1291 TRUE or FALSE to indicate the success of the channel key
1294 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Fixed MSVC++ project files and added missing files to
1297 Makefiles under win32/.
1299 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Do not add TCP_NODELAY flag if the operating system
1302 does not have it defined. Affected files are
1303 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1305 * Fixed buffer overflow from Irssi SILC Client. Affected
1306 file irssi/src/fe-common/core/themes.c.
1308 * Fixed double free in client library in the file
1309 lib/silcclient/client.c when disconnecting from server.
1311 * Applied double free patch from cras to Irssi SILC client.
1312 Affected files irssi/src/core/[modules/expandos].c
1314 * Fixed the disconnection handling to Irssi SILC Client.
1315 The application must call silc_client_close_connection
1316 in ops->connect client operation in case of failure of
1317 the connection. Affected file is
1318 irssi/src/silc/core/client_ops.c.
1320 * Do not set sock->protocol to NULL in the function
1321 silc_client_close_connection after executing the protocol's
1322 final callback since the sock might not be valid anymore.
1323 Affected file lib/silcclient/client.c.
1325 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Do not enable SILC_THREADS if the linking with libpthread
1328 did not happen. Affected file configure.in.pre.
1330 * Added notion to protocol specification that server must
1331 verify the sent authentication payload with CMODE when
1332 setting the channel founder key. Implemented it to the
1333 server. Affected file silcd/command.c.
1335 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Added _EXTRA_DIST SILC distribution variable to the
1338 distributions file. It is used to conditionally add extra
1339 files or directories to the specific distribution. Affected
1340 files ./prepare, Makefile.am.pre and distributions.
1342 Removed the `_' from the start of the distribution names.
1345 * Added README.WIN32 for instructions to compile the Toolkit
1348 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Fixed a double free in disconnection in the server. Affected
1351 file is silcd/server.c.
1353 * Fixed the lib/silcske/groups.c to work now also with GMP
1354 MP library. The string conversion did not work when using
1355 specific base and the base is indicated in the string as well.
1357 * Created win32/ directory which now includes MSVC++ specific
1358 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1359 It will appear only in the toolkit distribution
1361 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Changed the key material distribution function in case when
1364 the hash output is too short. The data is now concatenated
1365 a bit differently than it used to. Made the change to the
1366 SKE protocol specification.
1368 * Added better GMP detection to configure.in.pre. A patch
1371 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Fixed a minor bug in SKE that might cause some problem on
1374 some platforms. Affected file lib/silcske/silcske.c.
1376 * Added the cookie checking for initiator in the SKE. It checks
1377 that the responder returns the sent cookie unmodified. The
1378 affected file is lib/silcske/silcske.c. Added new SKE
1379 error type INVALID_COOKIE that can be sent during the
1380 negotiation. Fixed some memory leaks as well.
1382 * Added the "invalid cookie" error message to Irssi SILC client's
1385 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Added `task_max' field to the SilcClientParams to indicate
1388 the maximum tasks the scheduler can handle. If set to zero,
1389 default values are used. Affected file lib/silcclient/silcapi.h.
1391 * Fixed memory leaks in silc_client_close_connection. Affected
1392 file lib/silcclient/client.c.
1394 * Added silc_client_del_client_entry to client library to free
1395 all memory of given client entry. Affected file is
1396 lib/silcclient/idlist.[ch].
1398 * Added new functions silc_client_del_channel and
1399 silc_client_del_server to delete channel and server entries.
1400 Affected file lib/silcclient/[silcapi.h/idlist.c].
1402 * Removed silc_client_del_client_by_id from silcapi.h.
1404 * Fixed the INFO command to return the server's own info
1405 correctly when querying by Server ID. Affected file is
1408 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Removed the non-blocking settings in WIN32 code in the
1411 silc_sock_[read/write] and added SleepEx instead. Affected
1412 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1413 of input data is now checked with FIONREAD and ioctlsocket.
1415 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Call silc_schedule_task_del_by_context in the
1418 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1419 Affected file lib/silccore/silcprotocol.c.
1421 * Call silc_protocol_cancel for active protocols in the
1422 silc_server_close_connection if the funtion
1423 silc_server_free_sock_user_data has not been called.
1424 Affected file silcd/server.c.
1426 * Generic tasks cannot be deleted using the del_by_fd
1427 task deleting function since generic tasks does not match
1428 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1430 * Added a notion to SILCOPER help file that the SILCOPER works
1431 only on router server, not on normal server.
1433 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Added for WIN32 support for the new scheduler as well.
1436 Affected file lib/silcutil/win32/silcwin32schedule.c.
1438 * Fixed the SHA1 implementation to work on various platforms.
1440 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1443 API. It is part of the scheduler now. Everything else is
1444 as previously but some functions has changed their names.
1445 Checkout the lib/silcutil/silcschedule.h for the interface.
1446 Updated all applications to use the new interface. Affected
1447 files are lib/silcutil/silcschedule.[ch].
1449 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Found a bug in the SKE implementation. The HASH value,
1452 specified by the protocol, was not computed correctly. The
1453 public key of the responder was not added to the computation
1454 even though it is mandatory. Affected file lib/silcske/silcske.c.
1455 This unfortunately causes incompatibilities with older
1456 clients and servers.
1458 * Added WIN32 specific network init and uninit functions:
1459 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1460 the Winsock2. Affected file lib/silcutil/silcnet.h and
1461 lib/silcutil/win32/silcwin32net.c.
1463 * Set the socket always to nonblocking mode on WIN32 after
1464 reading data or writing data. Affected file is
1465 lib/silcutil/win32/silcwin32sockconn.c.
1467 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Fixed various compilation problems under WIN32. Affected
1470 files lib/silcutil/win32/silcwin32thread.c and
1471 lib/silcutil/win32/silcwin32schedule.c.
1473 * Removed all _internal.h #includes from public header
1474 files. Internal headers must never be included from
1477 Removed also the lib/silcske/payload_internal.h file.
1479 * All include files that may be needed (public and some others
1480 included by the public headers) by application developers are
1481 now copied to the ./includes directory. It does not copy any
1482 internal headers. Affected file Makefile.defines.pre and all
1483 Makefile.am's under lib/ and subdirs.
1485 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Do not change the ~/.silc directory's permissions automatically.
1488 Affected file irssi/src/silc/core/clientutil.c.
1490 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Do not cancel the protocol in silc_server_close_connection
1493 it might cause recursion. Now cancelled in the function
1494 silc_server_free_sock_user_data. Affected file silcd/server.c.
1496 * Fixed the silc_server_remove_clients_by_server to regenerate
1497 the channel keys correctly finally. Added also new function
1498 silc_server_remove_clients_channels to actually do it.
1499 Affected file silcd/server.c.
1501 * Fixed the silc_server_new_channel to not crash by giving
1502 wrong router to the new channel. Affected file is
1503 silcd/packet_receive.c.
1505 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1508 which is given as argument to the silc_client_alloc now.
1509 It can be used to configure the client and set various parameters
1510 that affect the function of the client.
1512 * The USERS command in server did not check whether the channel
1513 is private or secret. Affected file silcd/command.c.
1515 * Added new argument to the USERS command in protocol specification.
1516 The USERS command now can take the channel name as argument
1517 as well. Added support for this in client and server and
1518 updated the protocol specs.
1520 * Completed the GETKEY command in client. It can be now used
1521 to fetch also servers public key not only some clients.
1522 Affected files lib/silcclient/command[_reply].c.
1524 * Added silc_client_get_server to return server entry by the
1525 server name. Affected files lib/silcclient/silcapi.h and
1528 * Redefined the IDENTIFY command in protocol specification to be
1529 more generic. It now can be used to query information about
1530 any entity in the SILC Network, including clients, servers and
1531 channels. The query may be based either the entity's name
1532 or the ID. Added support for this in both client and server.
1534 Affected files silcd/command.c and lib/silcclient/command.c
1535 and command_reply.c.
1537 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1538 the _from_client and _from_server functions. Affected file
1541 * Added silc_client_get_channel_by_id_resolve to the file
1542 lib/silcclient/silcapi.h to resolve channel information by
1543 its ID. Added also silc_client_get_channel_by_id that
1544 does not resolve it from the server.
1546 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Added SilcServerEntry context into the client library
1549 to represent one server. The INFO command now allocates
1550 these to save the resolved server info. For now on the
1551 client library will also keep information about servers,
1552 connected and resolved with INFO.
1554 The INFO command now allocates the SilcServerEntry context
1555 and saves the server info there. The COMMAND_REPLY in
1556 the INFO now returns the parameters to application in
1557 same order as defined in the protocol specification.
1559 The entries are cached in the client->server_cache.
1561 * The INFO command is now issued after received the Client ID
1562 from the server. Affected file lib/silcclient/client.c.
1564 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1565 to the application as the mode changer might be server.
1566 It is guaranteed that NULL is not returned anymore to the
1567 application. Affected file lib/silcclient/client_notify.c.
1569 The ID Type is now also passed to the application so that
1570 it can check whether the returned entry is SilcClientEntry
1573 Added new function silc_client_get_server_by_id to return
1574 the server entry by ID. Affected files are the
1575 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1577 * Do not create the channel in the Irssi SILC Client when issuing
1578 the JOIN command but when received the sucessful JOIN command
1579 reply. Otherwise the channel might get created even though we
1580 could not join it. The Affected file is
1581 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1583 * Fixed a channel joining bug in router. The router must also
1584 check the channel modes, invite and ban lists etc. when serving
1585 the JOIN command sent by normal server. Affected file is
1586 silcd/command.c. The router now resolves the client's
1587 information from the server who sent the JOIN command if it
1588 does not know it, and processes the JOIN command only after
1591 * Changed the SilcCommandCb to take new argument; void *context2.
1592 Affected file lib/silccore/silccommand.h
1594 The second argument in the command callbacks in the server now
1595 includes the SilcServerCommandReplyContext if the command was
1596 called as pending command callback from the command reply.
1597 Otherwise it is NULL. When called as pending the status of the
1598 command reply will be checked and if it was erronous the
1599 error will be sent to the original sender of the command.
1600 This way the client always receives the error messages even
1601 though the server was actually the one who received the error
1602 when it resent the command to router, for example. Affected
1603 files silcd/command[_reply].[ch].
1605 * Fixed sending WHOWAS command's error message to client if
1606 the requested client could not be found. It was missing.
1609 * Changed the CMODE and CUMODE commands reply arguments in the
1610 protocol specification. The Channel ID is now sent in both
1611 of the commands to identify the channel. Implemented this
1612 new feature to the client and server. Affected files
1613 lib/silcclient/command_reply.c and silcd/command.c.
1615 * Made better checks for invite and ban lists in the JOIN
1616 command in server. Affected file silcd/command.c.
1618 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * The server now performs the incoming host IP/DNS lookup
1621 using the silc_socket_host_lookup and thus does not block
1622 the server anymore. Affected file silcd/server.c.
1624 * Completed the multi-thread support for SILC Scheduler in
1625 the lib/silcutil/silcschedule.c.
1627 * Fixed the configure.in.pre to detect the pthread correctly
1630 * Fixed a deadlock in silc_task_queue_wakeup in the file
1631 lib/silcutil/silctask.c.
1633 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Added new function silc_schedule_wakeup that is used in
1636 multi-threaded environment to wakeup the main thread's
1637 schduler. It needs to be used when a thread adds a new task
1638 or removes a task from task queues. After waking up, the
1639 scheduler will detect the task queue changes. If threads
1640 support is not compiled in this function has no effect.
1641 Implemented the wakeup mechanism to both Unix and WIN32
1642 systems. Affected files are lib/silcutil/silcschedule.[ch],
1643 lib/silcutil/unix/silcunixschedule.c and the
1644 lib/silcutil/win32/silcwin32schedule.c.
1646 * Added new function silc_task_queue_wakeup to wakeup the
1647 scheduler by the specified task queue. Affected file
1648 lib/silcutil/silctask.[ch].
1650 * The silc_socket_host_lookup_start now wakes up the scheduler
1651 after adding the timeout task. Affected file is
1652 lib/silcutil/silcsockconn.c.
1654 * The silc_socket_host_lookup is synchronous now if the threads
1655 support is not compiled in. However, the callback is still
1656 called asyncronously through the scheduler, anyway. Affected
1657 file lib/silcutil/silcsockconn.c.
1659 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Added new function silc_socket_host_lookup to perform
1662 asynchronous IP and FQDN lookups for the socket connection.
1663 Affected files lib/silcutil/silcsockconn.[ch].
1665 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1668 that may or may not compile the mutex support in.
1670 Changed the silc_mutex_alloc interface. It allocates the
1671 mutex now to the sent pointer and returns TRUE or FALSE.
1673 Affected file lib/silcutil/silcmutex.h.
1675 * Wrote the SILC Task Queue interface to support multi-threads.
1676 Affected file lib/silcutil/silctask.[ch].
1678 * Wrote the SILC Scheduler to support multi-threads. Affected
1679 file lib/silcutil/silcschedule.c.
1681 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1684 in lib/silcutil/win32/.
1686 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Defined SILC Mutex API and SILC Thread API and implemented
1689 them for Unix. Affected files are
1690 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1691 lib/silcutil/unix/silcunixmutex.c and
1692 lib/silcutil/unix/silcunixthread.c.
1694 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Fixed the silc_server_remove_clients_by_server's channel
1697 key re-generation. The hash table handling was incorrect
1698 and would not work with many channels. Affected file is
1701 * Fixed some memory leaks around the server code.
1703 * Rewrote the silc_server_get_users_on_channel to support IPv6
1704 based Client ID's. Affected file silcd/server.c.
1706 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1707 specification. However, a separate document must be written
1708 to define the detailed signing procedure and the payload
1709 associated with the flag. Defined the flag to the
1710 lib/silccore/silcchannel.h as well.
1712 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Changed the dynamic tables to static size tables in the
1715 lib/silccrypt/silchmac.c.
1717 * Removed GCC dependencies from the code. A patch by cras.
1719 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1721 * Do not show the error "Error receiving packet bla bla"
1722 in server if it really was not an error (-2 means that reading
1723 is pending). Affected file silcd/server.c.
1725 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1727 * Fixed a possible crash in silc_server_remove_clients_by_server
1728 in silcd/server.c. Fixed there also some memory leaks.
1730 * Fixed the silc_idlist_replace_client_id. It could replace
1731 wrong key in the hash table. Affected file silcd/idlist.c.
1733 * Do not check whether there are global users on the channel
1734 if the channel->global_users is FALSE. Affected functions
1735 silc_server_remove_from_one_channel and
1736 silc_server_remove_from_channels in silcd/server.c. Also,
1737 do not check if the removed client is local as we can be
1738 sure that global client was not removed from the channel
1739 and checking for global users is not needed.
1741 * The silc_server_remove_clients_by_server now re-generates
1742 the channel keys correctly for those channels that had
1743 clients removed from them. Affected file silcd/server.c.
1745 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1747 * Found the reason of random crashes in the server. We weren't
1748 ignoring the SIGPIPE signal (which can be sent in write())
1749 and it crashed the server. Affected file silcd/silcd.c.
1751 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Assure that sock->user_data is not NULL in the function
1754 silc_server_packet_send in silcd/packet_send.c.
1756 * Disconnect the remote connection if it could not be added
1757 to any ID lists in the server. The affected file is
1760 * Check in silc_server_packet_send[_real/dest] that the
1761 socket is not disconnecting and ignore the data if it is.
1762 Affected file silcd/packet_send.c.
1764 * Define inline to __inline on native WIN32 compilation.
1765 Affected file includes/silcwin32.h.
1767 * Added some explicit type casts for inline code since MSVC
1768 require them. Affected files lib/silcutil/silcbuffer.h,
1769 lib/trq/silcdlist.h and lib/trq/silclist.h.
1771 * Print warning in log files from now on if the packet
1772 decryption fails. Affected file silcd/server.c.
1774 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Changed the `say' client operation's interface to accept
1777 new `type' argument to indicate the type of the message sent
1778 by the library. The application may filter the library's
1779 messages according the type. The affected file is the
1780 lib/silcclient/silcapi.h.
1782 * Added two new functions to lib/silcclient/silcapi.h:
1783 silc_client_del_client and silc_client_del_client_by_id.
1784 Affected file lib/silcclient/idlist.c.
1786 * Moved the clientincludes.h from includes/ to silc/ and
1787 serverincludes.h from includes/ to silcd/.
1789 * The modes for the CMODE and CUMODE are now passed as
1790 uint32 for application with COMMAND_REPLY. The affected
1791 file is lib/silcclient/command_reply.c.
1793 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * /WHOIS without arguments shows client's own information.
1796 Affected file lib/silcclient/command.c.
1798 * Changed PING to not accept any arguments. The specs
1799 says that client can ping only the connected server so
1800 requiring an argument is not needed. Affected file is
1801 lib/silcclient/command.c.
1803 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Fixed a fatal bug in private message sending and reception
1806 encryption and decryption when using private message keys.
1807 The implementation was incorrect and did not follow the
1808 specification. It causd that some of the message were
1809 lost since it did not use the sending and receiving keys
1810 as the protocol suggests. This has been fixed and will cause
1811 incompatibilities with older clients when sending private
1812 message encrypted with private message keys. Affected files
1813 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1814 and various other in Irssi SILC Client.
1816 Added `responder' boolean argument to the functions
1817 silc_client_add_private_message_key[_ske] to indicate when
1818 the key is added as responder or initiator of the key
1821 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Removed the silc_ske_check_version function and created
1824 a SilcSKECheckVersion callback. Added also a function
1825 silc_ske_set_callbacks that is now used to set all SKE
1826 callbacks. The callback functions are not given to
1827 the SKE functions anymore, but this function is used to
1830 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1832 * Added `silc_version' argument to the silc_client_alloc
1833 to define the version of the application for the library.
1834 The library will use the version string to compare it
1835 against the remote host's (usually a server) version
1836 string. Affected file lib/silcclient/silcapi.h
1838 * Added the KE protocol context to Key Agreement context
1839 in client library so that we can abort the SKE if it
1840 is in process when we get timeout. Affected file is
1841 lib/silcclient/client_keyagr.c.
1843 * Do not resolve the client ID forever if it returns in the
1844 first time that such client does not exist. This was done
1845 for example with private message. Affected file is
1846 lib/silcclient/client_prvmsg.c.
1848 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Do not add regex.h for WIN32. The affected file
1851 includes/silcincludes.h.
1853 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1854 not work yet 100%. It generates the DLL's automatically
1855 when compiling with --with-win32 under cygwin.
1857 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * lib/contrib/regex.c is not compiled on WIN32.
1861 * Added silc_net_get_socket_opt function to the
1862 lib/silcutil/silcnet.h.
1864 * Added includes/silcwin32.h for WIN32 specific includes
1867 * Do not use ptime structure or any of the posix process
1868 functions on WIN32 in lib/silccrypt/silrng.c.
1870 * Added silc_gettimeofday to provide generic function
1871 for struct timeval on all platforms. Added the function
1872 to lib/silcutil/silcutil.h.
1874 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1877 library as they clearly belong there. As a plus side we
1878 can make the actual socket connection routines platform
1881 Added also new generic function silc_socket_read and
1882 silc_socket_write (that used to be silc_packet_[read/write].
1883 The implementation of these are platform specific.
1885 * Added WIN32 specific routines of silc_socket_[read/write]
1886 to lib/silcutil/win32/silcwin32sockconn.c.
1888 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Added preliminary support for native WIN32 compilation under
1891 cygwin (using the -mno-cygwin option for GCC) to the
1892 ./configure.in.pre. The --with-win32 now prepares the
1893 compilation for native WIN32.
1895 * Rewrote the SILC Scheduler interface in the file
1896 lib/silcutil/silcschedule.h. The scheduler is now context
1897 based and does not have anymore any global static scheduler.
1898 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1899 and created lib/silcutil/win32 directory for WIN32 based
1902 * Added Unix specific network routines to the
1903 lib/silcutil/unix/silcunixnet.c and the old
1904 lib/silcutil/silcnet.c includes now only generic routines.
1906 Added WIN32 specific network routines to the
1907 lib/silcutil/win32/silcwin32net.c.
1909 * Added Unix specific utility functions from the
1910 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1912 * Added WIN32 SILC Scheduler to the file
1913 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1916 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Do not handle JOIN notify in the server if the target client
1919 is not registered (idata->registered == FALSE). The affected
1920 file is silcd/packet_receive.c.
1922 * Update the nickrec->founder in event_cumode in the Irssi SILC
1923 client. Affected file irssi/src/silc/core/silc-channels.c.
1925 * Fixed the CUMODE_CHANGE notify handling in the server when
1926 server and router are announcing their clients on channels.
1927 Now the mode changes are saved and notified correctly. The
1928 affected file is /silcd/packet_receive.c.
1930 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1931 They really did not replace the cache entry in the ID Cache.
1932 Now they do that. Affected file silcd/idlist.c.
1934 * Fixed the KICK notify handling in the Irssi SILC client to
1935 update the channel records so that the kicked client does not
1936 appear to be on the channel. The affected file is
1937 irssi/src/silc/core/silc-channels.c.
1939 * Always update the conn->current_channel when executing command
1940 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1942 * Fixed the KILL notify handling in Irssi SILC client to remove
1943 the killed client on all channels.
1945 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1947 * Fixed the silc_parse_command_line to remove extra spaces
1948 from the start and end of the arguments. Affected file is
1949 lib/silcutil/silcutil.c.
1951 * Cancel and free any active protocol in the function
1952 silc_server_close_connection. Affected file silcd/server.c.
1954 * Cancel and free any active protocol in the function
1955 silc_client_close_connction. Affected file is
1956 lib/silcclient/client.c.
1958 * Do not execute the KILL command for clients that are in
1959 history (ie. they are not in the network). Affected file is
1962 * Fixed KILL notify handling, client does not crash anymore.
1963 Affected file irssi/src/silc/core/silc-channels.c.
1965 * Reduced the default packet buffer size from 2048 to 1024 in
1966 lib/silccore/silcpacket.c.
1968 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1969 counter to the SKE context that is incresed when the SKE library
1970 performs async operation outside the library. If the outside
1971 process frees the SKE context and FREED status will be set
1972 and the library will detect after the sync operation that the
1973 libary is freed. The affected files are
1974 lib/silcske/silcske[_status].[ch].
1976 * Resolve the client entry information in the function
1977 silc_client_channel_message to assure that NULL pointer is not
1978 passed as client entry to the application. */
1980 * Fixed the task timeout calculation to assure that there is
1981 never negative timeouts. The affected file is
1982 lib/silcutil/silcschedule.c.
1984 * Fixed the channel user mode notification sending in server.
1985 It was sent point-to-point to the router (or to server by router)
1986 but it needs to be destined to a channel. The routines now
1987 supports sending the channel user mode notifys to the channels
1988 when announcing clients and channels. Affected files are
1989 silcd/server.c and silcd/packet_receive.c.
1991 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1992 It did not actually replace the old channel entry in the cache.
1993 Affected file lib/silcclient/client_notify.c.
1995 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Fixed a possible crash in silc_packet_send_prepare. It now
1998 assures always that there is enough space in the buffer and
1999 at the tail area of the buffer (for MAC).
2001 Fixed the inbound buffer reallocation in silc_packet_read.
2002 It was old code and did not handle the reallocation correctly.
2005 The affected file is lib/silccore/silcpacket.c.
2007 * Fixed buffer overflow in silc_parse_nickname in the file
2008 lib/silcutil/silcutil.c.
2010 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2012 * make install generates new server keys only if there is not
2015 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2018 Added check that if the NOREPLY is set then we will not send
2019 the away message. This avoids infinite loop of away messages
2020 if both clients are away. The affected file is
2021 lib/silcclient/client_prvmsg.c.
2023 * Fixed client crash if /NICK was given without arguments.
2024 Affected file lib/silcclient/command.c.
2026 * Server does not send the invite list in INVITE command back
2027 to the client if the list was not altered. Added this notion
2028 to the protocol spec as well. Affected file silcd/command.c.
2030 Fixed possible crash in INVITE command by checking the
2031 value of silc_server_get_client_route command.
2033 * Fixed the INVITE notify type handling. The arguments are now
2034 taken in correct order and client does not crash. The affected
2035 file is irssi/src/silc/core/silc-channels.c.
2037 Removed the "Inviting xxx to channel" message from the
2038 client library away and let the application handle it.
2039 Affected file lib/silcclient/command.c. Added that message
2040 to Irssi SILC client's message formats.
2042 * Fixed CMODE command crash in client. It now checks the
2043 amount of arguments correctly and does not crash. The affected
2044 file is lib/silcclient/command.c.
2046 * Do not create new channel automatically in silc_channels_join
2047 but check whether the channel by that name already exists.
2048 Affected file irssi/silc/core/silc-channels.c.
2050 * Do not send the SERVER_SIGNOFF to router if the disconnected
2051 entity was the router. Affected file silcd/server.c.
2053 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2054 SILC client as it was missing from there.
2056 Added the handling of the KICK notify to the Irssi SILC client
2057 as it was missing. Added "you have been kicked" message to
2058 Irssi SILC client's message modules formats.
2060 Added the handing of the KILL notify to the Irssi SILC client
2061 as it was missing. Added the kill message module formats
2064 The affected file is irssi/src/silc/core/silc-channels.c.
2066 * The router did not save the channel mode the server announced.
2067 Affected file silcd/packet_receive.c.
2069 * Fixed a possible crash in INFO command in server. If the
2070 server did not provide the server info it crashed. Affected
2071 file silcd/command.c.
2073 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * Fixed the GETKEY command in the server to check also the
2076 global list. Otherwise the GETKEY would not work correctly
2077 in normal SILC server. Affected file silcd/command.c.
2079 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Fixed GETKEY crash, it crashed if the command did not succseed.
2083 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2086 is now real and not just an macro interface to GMP.
2088 Removed the entire GMP from the source tree and imported new
2089 NSS MPI library instead. Reason for removing GMP is that it is
2090 extremely large and compiles extremely slow. The NSS MPI
2091 is only a few files and compiles in less than 10 seconds.
2092 The speed is also about the same as GMP. The MPI is imported
2093 to lib/silcmath/mpi.
2095 If the system has GMP installed we will still use the GMP.
2096 If it is not then the NSS MPI will be compiled.
2098 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Merged a long nickname (127 characters long) crash bugfix from
2101 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2103 * Merged a freed memory reference bugfix from Irssi CVS tree.
2104 Affected file irssi/src/core/commands.c.
2106 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Added the server's public key sving and verification to the
2109 server when performing the SKE. This was missing and the
2110 remote server's (or router's) public key was accepted without
2111 checking whether we have it previously or trust it at all.
2112 Affected file silcd/protocol.c.
2114 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2116 * Check in the silc_server_timeout_remote if protocol is active
2117 and make sure that the protocol's final callback is called so
2118 that all memory if freed. Affected file silcd/server.c.
2120 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * silc_server_whois_send_reply crashed the server if the nickname
2123 was 127 characters long. Affected file silcd/command.c.
2125 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Added sanity check to the silc_server_new_client. If the hostname
2128 is provided inside username then check that the provided hostname
2129 really is the same as the resolved one. If the hostname was not
2130 resolved then check it from the public key. Affected file is
2131 silcd/packet_receive.c.
2133 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2134 if the server disconnected us and the connection is not valid
2135 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2137 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2138 the library to the lib/silcutil/silcutil.[ch].
2140 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * Close log file after open. Affected file
2143 lib/silcutil/silclog.c.
2145 * Check whether sock == NULL in silc_client_send_packet and return
2146 if it is. Affected file lib/silcclient/silcclient.c.
2148 * Check rec->entry == NULL in the Irssi SILC Client before
2149 sending the channel message. Affecte file is
2150 irssi/src/silc/core/silc-servers.c.
2152 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Merged a splitted window bugfix from Irssi CVS tree. The
2155 affected file is irssi/src/fe-text/textbuffer-view.c.
2157 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2158 It did not print nickname.
2160 * Improved the distributions system a bit.
2162 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2165 irssi/src/fe-text/gui-window.c.
2167 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2168 to in-active server. The affected file is
2169 irssi/src/silc/core/client_ops.c.
2171 * Resolve the client in USERS command reply if the entry does
2172 not have username resolved. The affected file is
2173 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2174 command to WHOIS command to really resolve stuff. The USERS
2175 is not used any more in any critical section so WHOIS can
2176 be used even though it might be slower than IDENTIFY.
2178 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2181 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Changed the protocol API a bit more consistent in the
2184 lib/silccore/silcprotocol.[ch].
2186 * Changed the following headers to ROBODoc format:
2188 lib/silccore/silcpayload.h
2189 lib/silccore/silcprotocol.h
2190 lib/silccore/silcsockconn.h
2192 All core library headers are now formatted.
2194 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2196 * Fixed a bug in Irssi SILC client; do not show that you are
2197 server/router operator if you really are not. Affected file is
2198 irssi/src/silc/core/client_ops.c.
2200 * Renamed silc_command_free_payload to silc_command_payload_free.
2201 Affected file lib/silccore/silccommand.h
2203 * Added silcmath.h to include the prototoypes of various routines
2204 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2207 * Changed the following headers to ROBODoc format:
2209 lib/silccore/silcchannel.h
2210 lib/silccore/silccommand.h
2211 lib/silccore/silcid.h
2212 lib/silccore/silcidcache.h
2213 lib/silccore/silcmode.h
2214 lib/silccore/silcnotify.h
2215 lib/silccore/silcpacket.h
2216 lib/silcmath/silcmath.h
2218 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Added checking to the server code not to start the server if
2221 ciphers and stuff are not configured properly. Affected files
2222 silcd/serverconfig.[h] and silcd/server.c.
2224 * Changed the layout of the header files of the public interfaces
2225 in the SILC libraries. The new layout supports ROBODoc
2226 documentation tool (and some others) so that it is easy to create
2227 a library reference manual. All the other headers and source
2228 code must still follow the CodingStyle document. Also source
2229 code must not include these ROBODoc stuffs, only the headers.
2230 Furthermore, all public interface headers must now be named
2231 by using `silc' prefix, example: silcapi.h, silccipher.h.
2232 Some files were renamed due to this. All the other headers
2233 must not be used as public interfaces. I will update the
2234 CodingStyle document later. Changed following headers, so far:
2236 lib/silcclient/silcapi.h
2237 lib/silccore/silcauth.h
2238 lib/silccore/silcprivate.h
2239 lib/silccrypt/silcdh.h
2241 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Removed silc_client_packet_send_flush from the client library
2246 as it is not needed. Affected file lib/silcclient/client.[ch].
2248 * Added printing of message of unresolved authentication method
2249 to the Irssi SILC client. Added it to the module formats.
2250 Removed the same message from the client library.
2252 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Added new distribution feature, DISTLABEL. Every distribution
2255 can define own preprocessor label that can be used in the
2256 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2257 file distributions, acconfig.h.pre and prepare.
2259 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Added Makefile.defines_int to include the actual definitions
2262 for Makefile.defines.in. Tested the new distribution system,
2263 created distributions and tested installation.
2265 * Added AWAY message printing to the Irssi SILC client. Added
2266 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2268 * Added SCONNECT command to call the SILC's CONNECT command.
2269 Cannot use CONNECT directly since Irssi uses that internally.
2270 Affected file irssi/src/silc/core/silc-servers.c.
2272 Added ACTION local command. It is same as ME command but takes
2273 the channel as mandatory argument.
2275 Rewrote some of the Irssi's help files to suite for SILC
2278 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2280 * Added Makefile.defines[.in] that should for now on be included
2281 in all Makefile.am file in the source tree. That file includes
2282 all common compilation definitions for SILC source tree.
2284 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Minor changes to the ./prepare script to change the package
2287 name according the distribution name to the configure.in.
2289 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2291 * Created new distribution system. Added file `distributions'
2292 that defines all the distributions that can be created out of
2293 the SILC source tree. The ./prepare script now reads that
2294 file to determine how to prepare the distributions. The
2295 first argument to the ./prepare is the name of the distribution
2296 and second is the version of the distribution. If given
2297 without arguments it creates the default (toolkit) distribution
2298 with the default version (defined in ./prepare).
2300 All Makefile.am files that are subject to the distributions
2301 are now named as Makefile.am.pre. These are ./Makefile.am
2302 and lib/Makefile.am. Others may be changed later.
2304 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Added invite list, ban list, some key management and connection
2307 error message printing to module formats in the Irssi SILC client.
2309 * Added new silc_client_set_away_message to set the away message
2310 that is back to the person who sent private message. The
2311 affected file lib/silcclient/silcapi.h and the
2312 lib/silcclient/client_prvmsg.c.
2314 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Fixed the private message sending in the Irssi SILC client,
2317 added local command KEY to the Irssi SILC client.
2319 Added key management and key agreement message formats to the
2320 irssi/src/fe-common/silc/module-formats.[ch].
2322 Added USERS (alias WHO) printing, server/router operator
2323 indication and LIST command printing to the module formats.
2325 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Fixed channel joining notify handling, cumode notify handling
2328 from Irssi SILC client.
2330 * Added SILC specific module-formats to the Irssi SILC client so
2331 that SILC specific message hilighting, colors etc is possible.
2332 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2334 Added channel mode, channel user mode, actions, notices,
2335 whois and whowas printing to the the module-formats.c.
2337 * Fixed a bug in channel deletion in the server. The channel
2338 is not left to the cache even if the channel founder auth mode
2339 is set when there are no users anymore on the channel. Affected
2340 file silcd/server.c.
2342 * The silc_net_localhost now resolves the entire hostname including
2343 the domain name. Affected file lib/silcutil/silcnet.c.
2345 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Changed the ask_passphrase client operation to be ascynchronous.
2348 It has now a completion callback and a context that the
2349 application must call after it has got the passphrase from
2350 the user. Affected files lib/silcclient/silcapi.h,
2351 lib/silcclient/protocol.c, lib/silcclient/command.c and
2354 Added SilcAskPassphrase callback that the application calls
2355 to deliver the passphrase to the library.
2357 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2358 The public key verification and especially a certificate
2359 verification is asynchronous procedure.
2361 Added new SILC_SKE_STATUS_PENDING status to indicate the
2362 request is pending and a callback will be called to finalize
2365 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2366 indicate that remote end did not send its public key (or
2367 certificate), even though we require it. Added check for this
2368 condition in the SKE. This was a security bug, now fixed.
2370 Defined new SilcSKEVerifyCbCompletion callback that is called
2371 when the verification process is completed.
2373 The affected files lib/silcske/silcske_status.h and
2374 lib/silcske/silcske.[ch].
2376 * Changed the verify_public_key client operation to be async
2377 as well. Defined SilcVerifyPublicKey callback that is used to
2378 indicate the success of the public key verification process.
2380 Changed the server and client to use the new async client
2383 * Changed the Irssi SILC client's internal scheduler to be called
2384 twice as many times as it used to be. As a result the client
2385 should be a bit faster now. Affected file is
2386 irssi/src/silc/core/silc-core.c.
2388 * Added support to Irssi SILC client of asynchronous public key
2389 verification and passphrase inquiry. Affected file is
2390 irssi/src/silc/core/silc-core.c.
2392 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Do not say "You have left channel %s" in client library.
2395 Moved it to the application. Affected files are
2396 lib/silcclient/command.c and silc/client_ops.c.
2398 * Fixed silc_client_get_clients. Command context was not
2399 duplicated and was freed memory in the callback. Affected
2400 file lib/silcclient/idlist.c.
2402 * Do not say "you are now talking..." on JOIN command in the
2403 client library. The appliation must handle it.
2405 * Do not say ".. changed topic to" in command reply in the
2406 client libary. The application must handle it.
2408 * Fixed TOPIC command sending in the client library.
2410 * Fixed a memory leak in silc_client_command_free in the file
2411 lib/silcclient/command.c.
2413 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Imported a modified version of Irssi client to the source tree.
2416 The Irssi will be used to create a new client called
2417 Irssi SILC. Imported to irssi/.
2419 Added silc_core_init_finish function to the Irssi. Affected
2420 file irssi/configure.in.
2422 A lot changes in the Makefile.ams around the irssi tree.
2424 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Do not rehash if the new size is same as the old size of the
2427 hash table, in the silc_hash_table_rehash*. The affected file
2428 lib/silcutil/silchashtable.c.
2430 * Replaced hash_table_del_by_context calls from the server
2431 (when channel->user_list and client->channels) to the
2432 hash_table_del as it is sufficient and faster.
2434 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Added silc_hash_table_list, silc_hash_table_get and the
2437 SilcHashTableList structure to provide an alternative way to
2438 traverse the hash table. The affected files are
2439 lib/silcutil/silchashtable.[ch].
2441 * Changed the server's idlist routines to use the hash table
2442 routines to optimize the code.
2444 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Replaced the client entry's `channel' list and channel entry's
2447 `user_list' list to hash tables for optimized lookup. Changed
2448 the code to use the hash table interface around the code.
2449 Affected file lib/silcd/idlist.[ch].
2451 * Added `auto_rehash' boolean argument to the function
2452 silc_hash_table_alloc to indicate whether the hash table should
2453 auto-rehash when it thinks is appropriate time. It will
2454 increase the hash table size if the there is twice as much
2455 entries in the table than the size of the table, and will
2456 decrease the size if there are twice as less entries than
2457 the size of the table.
2459 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2463 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * silc_idcache_purge_by_context deletes the entry now by context
2466 as it is supposed to do. Affected file lib/silccore/idcache.c.
2468 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2469 client is not anymore valid (WHOWAS givens the info) and not
2470 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2472 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2474 * Removed the `data' and `data_len' arguments from the ID Cache
2475 interfaces and added `name' argument. ID Cache does not handle
2476 anymore the binary data only a names associated with given ID.
2478 * When hashing a Client ID with silc_hash_id the entire ID is
2479 not hashed anymore, instead only the hash of the Client ID is
2480 hashed. This way we can access the Client ID from the cache
2481 with Client ID but with the hash of the ID (which is a hash of
2482 the nickname) as well without any difference in performance.
2484 Added also silc_idcache_find_by_id_one_ext to do one on one
2485 searching when we have the actual ID. Added also function
2486 silc_hash_client_id_compare. The affected files are
2487 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2489 * When hashing the name associated with a ID it is always done
2490 in lowercase. This way we can access the cache without worrying
2491 about case-sensitivity, even though, for example nicknames are
2494 * Fixed a bug in server with channel message sending. It put
2495 wrong ID type as destination ID. The affected file
2496 silcd/packet_send.c.
2498 * silc_idcache_del_by_context now deletes from all hash tables
2499 by context. Affected file lib/silccore/idcache.c.
2501 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Changed the client library to use the new ID Cache interface.
2504 Changes around the source tree.
2506 * Added silc_hash_table_rehash_ext to rehash with specific
2507 hash function. Affected file lib/silcutil/silchashtable.[ch].
2509 * Added silc_hash_string_compare to compare two strings in the
2510 hash table. Affected file lib/silcutil/silcutil.[ch].
2512 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added new function silc_idcache_del_by_context into the
2515 lib/silccore/idcache.[ch].
2517 * Changed the server's ID list routines to use the new ID Cache
2518 interface. Changes around the source tree.
2520 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Added silc_hash_table_del[_by_context]_ext functions in to the
2523 lib/silcutil/silchashtable.[ch].
2525 Removed silc_hash_table_find_all* routines and added new
2526 silc_hash_table_find_foreach to replace them.
2528 Added silc_hash_table_replace_ext function as extended
2529 replacing function. Separated the simple hash table interface
2530 from the extended hash table interface in the file
2531 lib/silcutil/silchashtable.h.
2533 * Fixed minor bugs and changed it to use some of the new
2534 hash table functions in lib/silccore/idcache.c
2536 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Added new function silc_hash_table_find_all to return all keys
2539 in the hash table by the specified key. As the hash table is
2540 collision resistant it also makes it possible to have several
2541 duplicate keys in the hash table. This function may be used to
2542 find all of the keys from the hash.
2544 Added user_context arguments to the SilcHashFunction,
2545 SilcHashCompare and SilcHashDestructor to deliver user specified
2548 Added new fuctions silc_hash_table_find[_all]_ext to do
2549 extended lookup with specified hash and compare functions and
2550 specified user contexts.
2552 Added new function silc_hash_table_add_ext to add the key
2553 with specified hash function and user context.
2555 Added new function silc_hash_table_foreach to traverse all
2556 entrys in the hash table. Added SilcHashForeach callback
2559 Added new function silc_hash_table_del_by_context to delete
2560 the entry only if the context associated with the key matches.
2562 Affected files are lib/silcutil/silchashtable.[ch].
2564 * Removed silc_hash_[server/client/channel]_id and added just
2565 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2566 silc_hash_id_compare to compare two ID's using as the hash table
2567 comparison function. Added also silc_hash_data to hash
2568 binary data and silc_hash_data_compare to compare it.
2570 * Removed silc_idlist_find_client_by_hash as it is not needed
2571 anymore. Affected file silcd/idlist.[ch].
2573 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2574 to use internally the SilcHashTable. The new ID Cache is a lot
2575 faster than the old one. Some of the ID Cache interface was also
2576 rewritten and obsolete and stupid functions were removed.
2578 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2580 * Added entry_count field to the SilcHashTable to keep the number
2581 of the entries in the table. Implemented the function
2582 silc_hash_table_rehash. Added new function
2583 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2585 Fixed a minor bug in silc_hash_table_free.
2587 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2588 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2589 into the lib/silcutil/silcutil.[ch].
2591 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Implemented a collision resistant hash table into the
2594 lib/silcutil/silchashtable[ch]. See the header and the source
2595 for the SilcHashTable API.
2597 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Merged dotconf version 1.0.2 into lib/dotconf.
2601 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Do not compile anything in lib/silcsim/* if the SIM support
2604 is not enabled. The tree should now compile without problems
2607 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Compiled the SILC under cygwin. Compiled and tested briefly
2610 without problems. More tests needed. The SIMs didn't compile
2613 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2615 * Fixed possible crash in silc_get_username in the
2616 lib/silcutil/silcutil.c.
2618 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Fixed a va_arg in silc/client_ops.c.
2622 * Oops, RC5 routines were named AES and caused some problems
2623 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2625 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Added new SilcIDIP structure into the lib/silccore/id.h and
2628 replaced the old `ip' fields from all SILC ID's to that type.
2629 This is a step towards IPv6 support.
2631 The silc_id_get_len takes now the ID as an extra argument.
2632 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2633 both IPv4 and IPv6 based ID's.
2635 The affected files are lib/silccore/id.[ch] and other files
2636 around the tree using these routines.
2638 * Removed the ID length arguments in server from various
2639 silc_server_send_notify_* routines -> they are not needed
2642 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Fixed memory leak in silc_encode_pem_file in the file
2645 lib/silcutil/silcutil.c.
2647 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Check minor version as well in the SKE. Affected files are
2650 silcd/protocol.c and lib/silcclient/protocol.c.
2652 * Added --identifier option to the server so that an identifier
2653 can be when creating the public key for the server. Affected
2654 file is silcd/silcd.c.
2656 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2657 lib/silccrypt/silcpkcs.c.
2659 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Register default ciphers and stuff when using -C option with
2662 the server. Affected file sildc/silcd.c.
2664 * Put back the servers public key filename format, it is better
2665 than the new one. For now, the client keys are saved with the
2666 new filename format. The affected file silc/client_ops.c.
2668 * Implemented the Cipher API for the rest of the ciphers that
2669 did not implement it or implemented it the wrong way.
2671 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Register default ciphers and stuff when using the -S option
2674 in the client. Affected file silc/silc.c. Same also when
2675 creating new key pair with -C option.
2677 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Fixed the silc_verify_public_key client operation function to
2680 save the public keys differently. The fingerprint is now
2681 used as filename and not the hostname. This way also the
2682 client keys are saved uniquely and not with hostnames. The
2683 affected file is silc/client_ops.c.
2685 * Trimmed the silc_hash_fingerprint function to remove extra
2686 whitespaces from the end of the fingerprint. The affected
2687 file is lib/silccrypt/silchash.c.
2691 * Added silc_cipher_register_default function to register all
2692 default ciphers. It can be used when configuration files
2693 does not exist and the application does not want any specific
2694 ciphers in any specific order.
2696 The SilcDList is now used as silc_cipher_list dynamically
2697 allocated cipher list. Removed the static list all together
2698 and now all ciphers must be allocated to the dynamic list.
2699 The silc_cipher_alloc routine was changed to check only the
2702 All silc_cipher_* routines that used to return int returns
2705 The affected files lib/silccrypt/silccrypt.[ch].
2707 * The same thing was done to silc_hash_* as for silc_cipher_*
2708 routines. Affected files lib/silccrypt/silchash.[ch].
2710 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2711 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2712 Added also silc_pkcs_[un]register[_default] functions.
2713 Removed the data_context from the PKCS API.
2715 * Added silc_hmac_register_default function to register default
2716 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2717 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2718 to unregister all hmacs at once.
2720 * Register the default ciphers, hash functions, PKCSs and HMACs
2721 if client's configuration file does not exist. The affected
2724 * The client did not load the hash functions from the SIM
2725 modules at all. Added support for this. Affected file is
2726 silc/clientconfig.c.
2728 * When decoding public key with silc_pkcs_public_key_decode, check
2729 the supported algorithm only if PKCS are registered. Affected
2730 file lib/silccrypt/silcpkcs.c. The same was done with the
2731 silc_pkcs_private_key_decode.
2733 * Fixed the SILC List routines to keep the list always in order.
2734 It used to change the list's order when traversing the list but
2735 not it preserves the order. Affected file lib/trq/silclist.h.
2737 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added the client library to use the SilcSocketConnection's
2740 reference counter (by silc_socket_dup) to prevent the bug that
2741 the socket object may be freed underneath async operation.
2743 * The name resolv library checking fixes in the configure.in.pre.
2746 * Created new version of the protocol drafts for future
2747 development. The -03 drafts are the ones that will be changed
2748 in the trunk now and the -02 will remain as they are.
2750 * Send list of CUMODE notifys to the router when announcing
2751 the channel users to the router. Affected file silcd/server.c.
2752 If the router receiving channel founder CUMODE for a channel
2753 that already has channel founder it will send CUMODE notify
2754 to the sender to remove the channel founder rights from the
2755 announced client. Affected file silcd/packet_receive.c.
2757 * The CUMODE notify may now use Server ID as well as the entity
2758 who changes the mode. Updated protocool specs.
2760 * Updated INSTALL and README files.
2762 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * New web pages in the http://silc.pspt.fi. The pages was
2769 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2771 * Implemented the [DenyConnectin] config section in the server.
2772 Added silc_server_config_denied_conn to check whether incoming
2773 connection is denied. Affected file silcd/serverconfig.[ch].
2775 * Do not check the ports when checking the incoming configuration
2776 data if the port is 0, meaning any. Affected file is
2777 silcd/serverconfig.c.
2779 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Fixed buffer overflow in silc_string_compare in the file
2782 lib/silcutil/silcutil.c.
2784 * Fixed double free in silc_server_command_leave in the file
2787 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Fixed the version checking in the server. Affected file is
2792 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Fixed the configuration data fetching when accepting new
2795 connections in the server. Affected file silcd/server.c.
2797 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Added `sender_entry' argument to the function
2800 silc_server_packet_relay_to_channel so that we can check
2801 whether some destination actually belongs to the same route
2802 the sender belongs (ie, we must not resend the packet to the
2803 sender). Affected file silcd/packet_send.[ch].
2805 * Added `servername' field to the SilcClientEntry in the server
2806 to hold the name of the server where client is from. Affected
2807 file is silcd/idlist.h.
2809 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Moved the channel message encrypting in the router betwen
2812 router connections from silc_server_channel_message to the
2813 silc_server_packet_relay_to_channel since we want to check
2814 whether we have anybody channel before encrypting anything.
2815 Affected files silcd/packet_[receive/send].c.
2817 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Fixed the [AdminConnection] server config section to support
2820 multiple entries. Affected file silcd/serverconfig.c.
2822 * Added support into the server to check the validity of the
2823 incoming connection before executing any KE or authentication
2826 * The connection configuration is now saved to the KE and
2827 connection auth protocol contexts and not fetched anymore in
2828 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2830 * The local hosts listenning address and port is also resolved
2831 now when starting the server. We want to have the socket object
2832 to include the real address and port for the listener. Added
2833 new function silc_net_check_local_by_sock into the files
2834 lib/silcutil/silcnet.[ch].
2836 * Fixed a broadcast bug in server -> do not broadcast if we
2839 * Fixed a routing bug. Do not route broadcast packets ever.
2840 Broadcast packets must be processed always and not routed since
2841 they may be destined to some other host than yourself and thus
2842 would get routed without no good reason. Affected file is
2845 * Added function silc_server_config_is_primary_route to check
2846 whether primary router connection has been configured (a router
2847 configuration that we are initiating). If there is not, we
2848 will assume that there is only two routers in the SILC network
2849 and we will use the incoming router connection as our primary
2850 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2852 * Changed the order of the broadcasting. Broadcast _after_ the
2853 packet has been processed not before. Affected file is
2856 * Fixed a [ClientConnection] parsing bug. The port was never
2857 parsed correctly thus resulting to port 0. Affected file
2858 silcd/serverconfig.c.
2860 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2861 argument and did not set the broadcast packet flag. Affected
2862 file silcd/packet_send.c. Fixed same bug in the function
2863 silc_server_send_notify as well.
2865 * If we receive NEW_ID packet for our own ID in the server, ignore
2868 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Removed the nickname from the Private Message Payload.
2873 Updated the code and the protocol specs.
2875 * Updated protocol specs for submitting to the IETF.
2877 * Tweaked the Random Number Generator a bit. Affected file
2878 lib/silccrypt/silcrng.c. Exported a new function
2879 silc_rng_[global]_add_noise which can be used to add more
2882 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Do not parse packets with different timeout when protocol
2885 is active -> may cause problem with rekey. Affected file
2888 * When server receives signoff notify it must not create
2889 new channel key if the client is on any channels since the
2890 sender of the signoff notify will create it.
2892 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Added printing of error messages during SKE protocol from the
2895 failure packet sent by server during SKE. Affected file
2898 * Removed the client's failure_callback handling with timeout
2899 and handle it immediately when received.
2901 * The SKE library returned wrong type in SUCCESS and FAILURE
2902 packets. They must be 32 bit MSB not 16 bit MSB.
2904 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Ok, rewrote the logic of the re-key and now it seems to work.
2907 I tested it on high traffic with frequent re-keys without
2908 problems. Added hmac_receive (and renamed hmac to hmac_send)
2909 in SilcClientConnection in lib/silcclient/client.h and
2910 in SilcIDListData in silcd/idlist.h. Also, removed the
2911 SilcPacketParserContext's cipher and hmac fields as they are
2912 not needed anymore and actually caused some problems when
2913 the ciphers and hmac's changed underneath the packet parser.
2915 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * If re-key protocol is active then process the incoming packets
2918 synchronously since we must assure that icoming packets encrypted
2919 with the old key is processed before the new keys is set to
2920 use. This is true other packets than for REKEY packets.
2921 Affected file silcd/server.c. The same was done to client library
2922 as well, affected file lib/silcclient/client.c.
2924 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * Fixed bug in client and server to accept the force send if
2927 the packet is send from silc_[server/client]_packet_process
2928 function. Otherwise the packets are never delivered, oops.
2930 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Disable force sending of packets when REKEY protocol is active.
2933 We must assure that no packet is sent directly when rekey is
2934 performed. All packets must be sent through packet queue.
2935 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2936 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2937 function is silc_[server/client]_packet_send_real to check
2940 * Replaced the SIM paths from example config files to
2941 /usr/local/modules. Also, make install creates now
2942 /usr/local/silc/logs directory to hold all the SILC server
2945 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Made the configure.in.pre work on Solaris. Patch by salo.
2949 * Made all ciphers compatible with non-x86 machines. Defined
2950 CBC mode macros into lib/silccrypt/ciphers_def.h.
2952 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Fixed the make install.
2956 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * When MAC computation fails the silc_packet_decrypt returned 0
2959 even though it was supposed to return -1. Fixed this. The
2960 affected file is lib/silccore/silcpacket.c.
2962 * Do not replace the config files in /etc/silc (in make install)
2963 if they already exist. Affected file ./Makefile.am.
2965 * Do not send re-key packets immediately but through packet queue.
2966 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2968 * Changed silc_net_check_host_by_sock to return FALSE if the
2969 IP/DNS could not be resolved. Though, it returns the IP address
2970 now even if it could not resolve it (but returns also FALSE).
2971 Affected file lib/silcutil/silcnet.[ch].
2973 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Added silc_pkcs_decode_identifier to decode the public key's
2976 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2977 Added also silc_pkcs_free_identifier. Added also new context
2978 SilcPublicKeyIdentifier.
2980 * Added -S option to the silc client. It is used to dump the
2981 contents of the specified public key file.
2983 * Changed the PKCS api to return the public key length when
2984 setting the public key.
2986 * Fixed a fatal bug in the public and private key file loading.
2987 Affected file lib/silccrypt/silcpkcs.c.
2989 * Execute the packet parsing for client with zero (0) timeout
2990 if the protocol is active. Affected file silcd/server.c.
2992 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Made the key generation options to the silcd program. Added
2995 -C option, equivalent to client's option.
2997 * Added new [ServerKeys] config section to the server. It
2998 configures the server's public and private key.
3000 * Defined generic Public Key Payload into the protocol
3001 specification to send specific type of public keys and
3004 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3005 public key or certificate.
3007 * Implemented the GETKEY command to the server and to the
3008 client library and on user interface.
3010 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Made preliminary `make install' work.
3014 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Added SilcServerRekey context into silcd/idlist.h.
3018 * Added the PFS support as defined in the specification to the
3019 SKE protocol. Affected files lib/silcske/*.c.
3021 * Added `ske_group' field to the SilcServerRekey context to hold
3022 the number of the SKE group that is used with PFS in re-key.
3023 Affected file silcd/idlist.h.
3025 * Added PFS re-key support to the server. Affected file is
3028 * Added silc_protocol_cancel to cancel execution of the next
3029 state of the protocol. Affected file is
3030 lib/silccore/silcprotocol.[ch].
3032 * Added the re-key support with and without PFS to the client
3033 library. Re-key is performed once in an hour, by default.
3035 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3036 Added silc_client_rekey_callback and silc_client_rekey_final.
3037 Affected files are lib/silcclient/protocol.[ch] and
3038 lib/silcclient/client.[ch].
3040 * Removed the `hmac_key' and `hmac_key_len' fields from the
3041 SilcClientConnection structure; not needed. Affected file is
3042 lib/silcclient/client.h.
3046 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Do not ask whether user wants to use the negotiated private key
3049 for private messages, just use it. Affected file is
3050 silc/local_command.c.
3052 * Added `send_enc_key' and `enc_key_len' fields to the
3053 SilcIDListData structure since they are needed in the re-key
3054 phase. Affected file is silcd/idlist.[ch].
3056 * Implemented the simple re-key protocol into the server.
3057 Affected files silcd/server.c and silcd/protocol.[ch]. The
3058 re-key will be performed once in an hour, by default.
3060 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3061 Added silc_server_rekey, silc_server_rekey_callback and
3062 silc_server_rekey_final.
3064 * Removed Tunneled flag from the protocol. Updated the code
3065 and the specifications.
3067 * Adde `pfs' field to the SilcIDListData to indicate whether
3068 the PFS is to be performed in the re-key. Affected file is
3071 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3074 int64 of at least the xintXX size. If void * is less that 4
3075 bytes uint32 * will be used. Defined bool as boolean.
3077 * Changed _ALL_ unsigned long and unsigned int to uint32,
3078 unsgined short to uint16 in the source tree.
3080 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3081 not handle clients that has entry->data.registered == FALSE.
3082 They are not in the network anymore. Affected file is
3085 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Implemented the sending of the SERVER_SIGNOFF notify in the
3088 server. Affected file is silcd/server.c.
3090 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3091 Added also silc_notify_payload_encode_args into the
3092 lib/silccore/silcnotify.[ch].
3094 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3095 Affected file silcd/packet_receive.c.
3097 * Implemented the SERVER_SIGNOFF notify handling in the client
3098 library. Affected file lib/silcclient/client_notify.c. Also,
3099 implemnted the printing of the SERVER_SIGNOFF info to the
3100 application. Affected file silc/client_ops.c.
3102 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3103 if the deleting was successful. Affected file silcd/idlist.[ch].
3105 * Added support for public key authentication in the connection
3106 authentication protocol in the client library. Affected file
3107 lib/silcclient/protocol.c.
3109 * Changed the server's silc_idlist_get_clients_by_* interface
3110 to support already allocated array so that new entries may be
3111 added to pre-allocated array. Affected file silcd/idlist.[ch].
3112 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3113 and command replies.
3115 * All command reply functions in the server now calls the
3116 pending command callback even if error occured. This way the
3117 error will be delivered to the client as well. Affected files
3118 silcd/command.c and silcd/command_reply.c.
3120 * Fixed INFO command to return local server's info if no server
3121 was provided. Affected file lib/silcclient/command.c.
3123 * Removed RESTART command for good. Updated the code and the
3126 * Rewrote parts of the task system. It is a bit simpler now.
3127 Removed unsued task priorities. The affected files are
3128 lib/silcutil/silctask.[ch].
3130 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Moved the USERS printing from the library to the application.
3133 Affected files lib/silcclient/command.c and silc/client_ops.c.
3135 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Added channel key re-key support. The re-key is perfomed
3140 only by the router and is done once in an hour. Added `rekey'
3141 field to the SilcChannelEntry in the server. Affected files
3142 silcd/server.c and silcd/idlist.h.
3144 * Added silc_task_unregister_by_context into the file
3145 lib/silcutil/silctask.[ch].
3147 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Added SILC_UMODE_GONE mode to indicate when the client is not
3150 present in the SILC network. Added also support to the local
3151 command AWAY that will set this mode. Added support of showing
3152 "xxx is gone" in WHOIS command. The USERS command shows the
3153 gone status as well.
3155 * Fixed setting server and router operator privileges in the
3156 server's UMODE command. Affected file silcd/command.c.
3158 * Merged the SKE KE1 and KE2 payloads into one payload. The
3159 new KE payload is equivalent to the old KE2 payload.
3161 Cleaned up the SKE Start Payload parsing. It now uses the
3162 simple buffer unformatting to do the parsing. A lot faster
3165 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3166 to the SKE that is used to indicate whether both of the SKE
3167 parties should perform authentication. By default only the
3168 responder performs authentication. By setting this flag also
3169 the initiator must do authentication. By default it is unset
3170 since in normal SKE case, client to server connection, only
3171 the responder should do authentication. When doing SKE between
3172 two clients both should perform authentication. Updated the
3173 code and the protocol specs.
3175 * A little fix to IDENTIFY command in the server. Search the
3176 client first by hash not nickname. Affected file is
3179 * Fixed the silc_client_close_connection to support closing
3180 the client to client connections wihtout deleting too much
3181 data. Affected file lib/silcclient/client.c.
3183 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3184 are received if protocol used to be active but is not anymore
3185 the application would crash due to NULL pointer dereference.
3186 Affected files silcd/server.c and lib/silcclient/client.c.
3188 * Added `hash' field to the SilcClientConnection to include
3189 the hash function negotiated in the SKE protocol.
3191 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3192 to set the channel founder authentication data. A client can
3193 claim the founder rights later by providing the authentication
3194 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3195 This way the channel founder can regain the channel founder
3196 privileges even it is left the channel. This works only on
3197 local server and the client must be connected to the same
3198 server to be able to regain the founder rights. Updated the
3199 protocol specs accordingly.
3201 Added support to the CMODE command in the client to set the
3202 founder auth data. Read the README to see how to set it.
3204 Added support to the CUMODE command to claim the founder
3205 rights. Read the README to see how to do it.
3207 Added support for the founder authentication to the Channel
3208 Entry in the server. Affected file silcd/idlist.h.
3210 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3211 server's CMODE command. Affected file silcd/command.c.
3213 * Added the following new functions into lib/silccore/silcauth.[ch]:
3214 silc_auth_get_method and silc_auth_get_data.
3216 * The server now saves the remote hosts public key to the
3217 SilcIDListData pointer. Affected file silcd/protocol.c.
3219 * The normal server now does not remove the channel entry from
3220 the cache if the founder authentication data is set. It used
3221 to remove it if the founder was the last one on the channel on
3222 the server and left the channel. The auth data is saved and
3223 if the channel is re-joined later the old entry is used with
3224 the old auth data. Affected files silcd/command_reply.c and
3227 * Removed the `pkcs' field from the SilcIDListData structure
3228 in the server; it is not used. Affected file silcd/idlist.h.
3230 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Fixed packet processing on slow links. Partial packets were
3233 never re-processed because the incoming data buffer was cleared
3234 by the application. Application must not directly clear the
3235 sock->inbuf, the packet processing routines handle it. Fixed
3236 this in client library and in server.
3238 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Fixed the WHOIS and IDENTIFY send reply function to really
3241 check whether to send list or just one entry. Affected file
3244 * Cleaned up the LEAVE command's channel key distribution. The
3245 affected file silcd/command.c.
3247 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3248 can enforce the channel mode as well. In that case the ID
3249 includes the ID of the server. The code now enforces the
3250 mode change if the router have different mode than the server.
3252 * The notify client operation with CMODE_CHANGE notify can now
3253 return NULL client_entry pointer if the CMODE was not changed
3254 by client. Application must check for this.
3256 * Added <Server ID> argument to INFO command to support server
3257 info fetching by Server ID.
3259 * Added silc_server_announce_get_channel_users to get assembled
3260 packets of channel users of the specified channel. Affected
3261 file silcd/server.[ch].
3263 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3264 was freed underneath the ID Cache.
3266 * Re-announce clients when the server received CHANNEL_CHANGE
3267 notify from the router. Affected file silcd/packet_send.c.
3269 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3272 crashed since it did not handle the fact that there is no cipher
3273 called "3" and didn't check the error condition. Now fixed.
3275 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3276 flag. It can be used to send message requests.
3278 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Implemented the RESTART command in the client.
3282 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3283 notice type messages. Added notice printing to the user
3286 * The channel keys are not re-generated if the channel's mode
3287 is PRIVKEY, ie private key on the channel exists. Affected
3288 files silcd/server.c and silcd/command.c.
3290 * Fixed a little bug in channel message delivery when channel
3291 private keys are set in the server. Affected file is
3292 silcd/packet_send.c.
3294 * Changed the setting on channel->on_channel = TRUE from the
3295 silc_client_save_channel_key to the JOIN command reply. The
3296 key payload is not received if the private channel key is set.
3297 Affected file lib/silcclient/command_reply.c and the
3298 lib/silcclient/client_channel.c.
3300 * When the CMODE_CHANGE notify is sent and the channel private
3301 key mode is removed the channel key must be re-generated in
3302 other cells as well. Added this support for the router in the
3303 silcd/packet_receive.c.
3305 * Added new local command NOTICE to send notice message on
3306 channel. Affected file silc/local_command.[ch].
3308 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Added new local command ME to the client. It is used to send
3311 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3312 some action. Affected file silc/local_command.[ch].
3314 * Changed channel_message and private_message client operations
3315 to deliver the message flags to the application. Added also
3316 the `flags' arguments to the silc_client_send_channel_message
3317 and silc_client_send_private_message functions. Affected file
3320 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Redefined the Private Message Payload to support private message
3323 keys and to support the new private message flags. Updated
3324 the protocol specs. Flags makes it possible to have for example
3325 CTCP style messages.
3327 * Added new type SilcPrivateMessagePayload and defined an API
3328 for it in the lib/silcclient/silcprivate.[ch].
3330 * Tested private message private keys successfully. Tested the
3331 private message key set, unset and list commands with the new
3334 * Redefined the Channel Message Payload to include the channel
3335 message flags (equal with private message flags) to support
3336 for example CTCP style messages.
3338 * Defined some of the message (for channel and private message)
3339 flags. Updated the protocol specs and added the flags to the
3340 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3342 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Added SilcKeyAgreementStatus type to the key agreement routines
3345 to indicate the current status and error if one occured.
3346 The status types are defined in the lib/silcclient/silcapi.h.
3348 * Added new local command KEY that is used to set and unset private
3349 keys for channels, set and unset private keys for private messages
3350 with remote clients and to send key agreement requests and
3351 negotiate the key agreement protocol with remote client. The
3352 key agreement is supported only to negotiate private message keys,
3353 it currently cannot be used to negotiate private keys for channels,
3354 as it is not convenient for that purpose.
3356 * Fixed a minor pending callback setting bug in the function
3357 silc_client_get_client_by_id_resolve, now the function works.
3358 Affected file lib/silcclient/idlist.c.
3360 * Added function silc_net_get_local_port to get local bound
3361 port by socket. Added to lib/silcutil/silcnet.[ch].
3363 * Added `sockets' and `sockets_count' fields to the SilcClient
3364 object. They hold the sockets of the listenning sockets in
3365 the client. Listenning sockets may be for example the key
3366 agreement server. Affected file lib/silcclient/client.[ch].
3367 Added functions the silc_client_add_socket and the
3368 silc_client_del_socket. They are exported to the application
3371 * Added ~./silc/clientkeys to support other client's public keys.
3373 * Renamed verify_server_key client operation to verify_public_key
3374 and added one argument to indicate the type of the connection
3375 (server, client etc.).
3377 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Added silc_server_connection_auth_request to handle the
3380 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3381 silcd/packet_receive.[ch].
3383 * Added silc_server_send_connection_auth_request into the
3384 silcd/packet_send.c to send the connection auth request packet.
3386 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3389 * Fixed the public key authentication in responder side in the
3390 server. The `auth_data' pointer includes the SilcPublicKey
3391 not the path to the public key. Affected file silcd/protocol.c.
3393 * Implemented the public key authentication in the initiator side
3394 in the server. Affected file silcd/protocol.c.
3396 * Removed the [RedirectClient] config section from the server
3397 configuration. Is not needed and I don't want to implement it.
3399 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Cleaned up the CMODE command in the server. It now works
3402 correctly and supports all the modes defined in the protocol.
3403 Affected file is silcd/command.c.
3405 * Added `hmac_name' field to the SilcChannelEntry in the server
3406 to hold the default HMAC of the channel. It can be set when
3407 creating the channel (with JOIN command). Affected files
3410 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3411 type to indicate the change of the current cipher and hmac
3412 on the channel. Client can safely ignore the <cipher> argument
3413 (if it chooses to do so) since the CHANNEL_KEY packet will
3414 force the channel key change anyway. The <hmac> argument is
3415 important since the client is responsible of setting the new
3416 HMAC and the hmac key into use.
3418 * Fixed the CMODE command in the client library as well.
3420 * Tested CMODE command in router environment successfully.
3422 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Show the version of the remote client (or server) when connecting
3425 to the server. It is logged to the log file. Affected file
3426 is silcd/protocol.c.
3428 * Fixed the KILLED notify handling in the client library. The
3429 client must be removed from all channels when receiving the
3432 Also, do not remove the client entry when giving the KILL
3433 command but when the KILLED notify is received.
3435 * Removed silc_idlist_find_client_by_nickname from the server.
3436 Not needed anymore. Affected files silcd/idlist.[ch].
3438 * Implemented the CHANNEL_CHANGE notify type handling to the
3439 server. Affected file silcd/server.c.
3443 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Added silc_server_send_notify_invite to send the INVITE
3446 notify between routers.
3448 * Implemented the INVITE command correctly to the server.
3450 * Implemented the INVITE notify type handling in the server.
3452 * Implemented the INVITE command to the client library and on the
3455 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Added function silc_server_get_client_resolve to find the
3458 client entry by ID from all ID lists and then resolve it
3459 (using WHOIS) if it cannot be found. Affected file is
3462 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Implemented the BAN command to the client library.
3466 * The JOIN command in the server now checks the invite list
3469 * Changed the silc_command_reply_payload_encode_va and the
3470 silc_command_payload_encode_va to support that if argument is
3471 NULL it ignores and checks the next argument. Affected file
3472 lib/silccore/silccommand.c.
3474 * Added silc_server_send_notify_ban to send the BAN notify
3475 type between routers.
3477 * Chaned the silc_notify_payload_encode to support that if
3478 argument is NULL it ignores and checks the next argument.
3479 Affected file lib/silccore/silcnotify.c.
3481 * Tested ban lists in router environment successfully.
3483 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Implemented BAN command to the server, in silcd/command.[ch].
3487 * Removed the BAN and INVITE_LIST modes from the CMODE command
3490 * Added function silc_string_match to regex match two strings.
3491 Affected files lib/silcutil/silcutil.[ch].
3493 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Redefined parts of the SilcChannelEntry in the server to support
3496 the new ban and invite lists.
3498 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Redefined the INVITE command. The same command can be used to
3501 invite individuals to the channel but also to manage the invite
3502 list of the channel (to add to and remove from the invite list).
3503 Updated the protocol specs.
3505 * Added new command SILC_COMMAND_BAN that can be used to manage
3506 the ban list of the channel. Updated the protocol specs.
3508 * Removed the channel modes: the SILC_CMODE_BAN and the
3509 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3510 in the CMODE command. The equivalent features are now available
3511 using INVITE and BAN commands. Updated the protocol specs.
3513 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3514 in the network about change in the current ban list. The notify
3515 type is not used by the client.
3517 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3518 support the invite lists.
3520 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Added new function silc_string_regexify that converts string
3523 including wildcard characters into regex string that can
3524 be used by the GNU regex library. Added into the file
3525 lib/silcutil/silcutil.[ch].
3527 Added silc_string_regex_combine to combine to regex strings
3528 into one so that they can be used as one regex string by
3529 the GNU regex library. Added into the file
3530 lib/silcutil/silcutil.[ch].
3532 Added silc_string_regex_match to match two strings. It returns
3533 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3535 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Imported GNU regex to the soruce tree into lib/contrib.
3538 Fixed some compiler warning from the regex.c.
3540 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Fixed MOTD command in the server to work in router environment.
3544 * Fixed the MOTD command in the client library to support
3545 the server argument in the command.
3547 * Added `nickname_len' argument to the silc_idlist_add_client
3548 in the server, as the `nickname' argument may be binary data
3551 * Added silc_idlist_get_channels to return all channels from
3554 * Implemented LIST command to the server. Affected file is
3557 * Implemented the LIST command to the client library and on the
3560 * Added [<user count>] argument to the LIST command reply.
3561 With private channels the user count is not shown.
3563 * Updated TODO and README.
3565 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * The client entry's data.registered must be TRUE even with
3568 global client entry on global client list. The data.registered
3569 is used to check whether the client is anymore in the network,
3570 for example with WHOWAS command so it must be valid.
3572 * Fixed the WHOWAS command in the server. It now actually works
3573 in router environment. Added function into silcd/command_reply.c
3574 silc_server_command_reply_whowas_save.
3576 * Added silc_idlist_purge function to the silcd/idlist.c
3577 to periodically purge the ID Cache.
3579 * Fixed INFO command in the server. It works now in router
3580 environment. Added <server name> argument to the INFO command
3581 reply. Updated the protocol specs.
3583 * Fixed minor bug in silc_idcache_purge to not purge if the
3584 expire value is zero.
3586 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3587 they were buggy because of the WHOWAS information.
3589 * Fixed local command MSG to handle the async resolving of
3590 the remote client properly. It used to fail the first MSG.
3591 Affected file silc/local_command.c.
3593 * Added `data_len' field to SilcIDCache context.
3595 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Update TODO. Todo in commands in the server.
3599 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3602 used by routers as broadcast packet to inform other routers
3603 about the changed user mode.
3605 Implemented the notify handling in the server. Affected file is
3606 silcd/packet_receive.c. Added the function
3607 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3609 * Added new generic Channel Payload and deprecated the New Channel
3610 Payload. The New Channel Payload is now the generic Channel
3613 * Added new argument `mode' to the silc_server_send_new_channel
3614 as it is required in the Channel Payload now.
3616 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3617 and created a new and real SilChannelPayload to represent the
3618 new generic Channel Payload. Implemented the encode/decode
3619 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3621 * Added silc_server_get_client_channel_list to return the list
3622 of channels the client has joined for WHOIS command reply.
3623 Affected file silcd/server.[ch].
3625 * Implemented the channel list sending in the WHOIS command reply
3626 in server and in the client.
3628 Implemented the channel list displaying on the user interface
3629 as well. Affected file silc/client_ops.c.
3631 * Added silc_channel_payload_parse_list to parse list of Channel
3632 Payloads. It returns SilcDList list of SilcChannelPayloads.
3633 Client for example can use this function to parse the list of
3634 channels it receives in the WHOIS command reply. The caller
3635 must free the list by calling silc_channel_payload_list_free.
3636 Affected files lib/silccore/silcchannel.[ch].
3638 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Added one new argument <user mode> to the WHOIS command reply
3641 to return the mode of the user in SILC. Updated the protocol
3644 Implemented it to the server and client.
3646 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Fixed the mode printing on the user interface on joining.
3649 Affected file silc/client_ops.c.
3651 * Implemented the UMODE command and user modes in general to the
3652 client library and to the user interface.
3654 * Implemented the UMODE command to the server.
3656 * The server now sends UNKNOWN_COMMAND error status if client sends
3657 unknown command. Affected file silcd/command.c.
3659 * All server commands now handle the command identifier the right
3660 way when sending the command reply to the client. The client can
3661 use to identify the command replies with the identifier.
3663 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added silc_server_get_client_route to resolve the route to
3666 the client indicated by the client ID. Affected file is
3669 * Added silc_server_relay_packet as general function to relay
3670 packet to arbitrary destination. This deprecates functions
3671 like _send_private_message_key, _relay_notify etc. Affected
3672 file is silcd/packet_send.[ch].
3674 Removed silc_server_send_key_agreement,
3675 silc_server_send_private_message_key and
3676 silc_server_packet_relay_notify functions from the file
3677 silcd/packet_send.[ch].
3681 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3682 server. Affected file silcd/packet_receive.[ch].
3684 * Implemented the KILL command to the client. Implemented the
3685 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3686 Affected files lib/silcclient/command[_reply].c and
3687 lib/silcclient/client_notify.c. Implemented the KILL notify
3688 printing in the user inteface.
3690 * Fixed a lot silc_parse_nick memory leaks from the client
3691 library in the file lib/silcclient/command.c.
3693 * Changed the silc_server_send_notify_on_channels's `sender'
3694 argument from SilcSocketConnection to SilcClientEntry to
3695 check the sender as entry and not as connection object and not
3696 to send to the client provided as argument. The affected file
3697 is silcd/packet_send.[ch].
3699 * The notify packets that are destined directly to the client used
3700 to not to be processed by the server. Now changed that and the
3701 server processes all notify packets. After relaying the packet
3702 to the client the notify packet is processed in the server.
3704 * The silc_server_free_client_data now checks whether there is
3705 pending outgoing traffic for the client and purges the data to
3706 the network before removing the client entry.
3708 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3711 an client is killed from the SILC Network. Updated the protocol
3714 Added new function silc_server_send_notify_killed to the
3715 silcd/packet_send.[ch].
3717 * Added function silc_server_packet_relay_notify to relay notify
3718 packets that are destined directly to a client. In this case
3719 the server does not process the notify packets but merely relays
3720 it to the client. Affected file silcd/packet_send.[ch].
3722 Added also silc_server_packet_process_relay_notify to check
3723 whereto relay the notify. Affected file is
3724 silcd/packet_receive.[ch].
3726 * Implemented the KILL command to the server.
3730 * Added the backup schema desgined last fall to the protocol
3731 specs for everyone to see. The specification is in the
3732 *-spec-xx.txt draft and the packet type definitions for the
3733 backup routers is in *-pp-xx.txt draft. Thusly, added also
3734 new packet type SILC_PACKET_CELL_ROUTERS.
3736 * A big security problem in the implementation discovered. The
3737 signoff of an client did not cause new channel key generation
3738 which it of course should've done. The channel keys must be
3739 always re-generated when client leaves (or signoffs) the channel.
3740 The silc_server_remove_from_channels funtion now handles
3741 the channel key re-generation.
3743 * Added `sender' argument to the silc_server_send_notify_on_channels
3744 to not to send the client provided as argument. Affected file
3745 silcd/packet_send.[ch].
3747 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Implemented OPER and SILCOPER commands into the server and
3752 * Added silc_auth_verify and silc_auth_verify_data to verify
3753 the authentication directly from the authentication payload.
3754 It supports verifying both passphrase and public key based
3755 authentication. Affected file lib/silccore/silcauth.[ch].
3757 * Added `hash' field to the SilcIDListData structure. It is the
3758 hash negotiated in the SKE protocol. Affected file is
3761 * Slight redesigning of the SilcAuthPayload handling routines.
3762 Do not send SilcPKCS but SilcPublicKey as argument.
3764 * Implemented the public key authentication support to the
3765 serverconfig. The public key is loaded from the provided path
3766 and saved as authentication data to void * pointer. Thus,
3767 changed the unsigned char *auth_data to void *auth_data;
3769 * Fixed SHUTDOWN command to send the reply before the server
3770 is shutdown. :) Affected file silcd/command.c.
3772 * Fixed fatal bug in CONNECT command. The hostname was invalid
3773 memory and server crashed. Affected file silcd/command.c.
3775 * Fixed fatal bug in CLOSE command. The server_entry became
3776 invalid but was referenced later in the command. Affected file
3779 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Fixed fatal bug in failure packet handling. Server ignored
3782 the failure and thus crashed when it came.
3786 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3789 that the command may be executed only once in (about) 2 seconds.
3790 The old SILC_CF_LAG flag is same but allows command bursts up
3791 to five before limiting.
3793 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3794 server code. Various commands now includes the CF_LAG_STRICT
3795 flag to disallow any kind of miss-use of the command.
3797 * Fixed the silc_buffer_unformat to not to allocate any data
3798 if the length of the data is zero. It used to allocate the
3799 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3801 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Changed the format of AdminConnection configuration section
3804 in the server. Added username of the admin to the format.
3805 Affected files silcd/serverconfig.[ch].
3807 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3808 to return admin configuration data by host, username and/or
3811 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3813 * Implemented WHOWAS command to the server. Added the functions:
3815 silc_server_command_whowas_parse,
3816 silc_server_command_whowas_send_reply,
3817 silc_server_command_whowas_from_client and
3818 silc_server_command_whowas_from_server
3820 * Added <Client ID> argument to the WHOWAS command reply. Updated
3821 the protocol specs accordingly.
3823 * Implemented WHOWAS command and command_reply to the client
3826 Implemented the WHOWAS printing on the user interface.
3828 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Added new argument to the WHOWAS command reply, the real name.
3831 It is an optional argument. Updated the protocol specs.
3833 * Added SilcIDCacheDestructor callback that is registered when
3834 the SilcIDCache is allocated. The callback is called when
3835 an cache entry in the ID Cache expires, or is purged from the
3836 cache. Added into lib/silccore/idcache.[ch].
3838 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3839 to destruct the client entries when the cache entry expires.
3840 Other ID Cache's in server and in the client library ignores
3843 * If the ID Cache entry's `expire' field is zero then the entry
3844 never expires. Added boolean `expire' argument to the
3845 silc_idcache_add function in the lib/silccore/idcache.[ch].
3846 If it is TRUE the default expiry value is used.
3848 * Added silc_server_free_client_data_timeout that is registered
3849 when client disconnects. By default for 5 minutes we preserve
3850 the client entry for history - for WHOWAS command.
3852 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Added support to the server to enforce that commands are not
3855 executed more than once in 2 seconds. If server receives
3856 commands from client more frequently, timeout is registered
3857 to process the commands. Affected file silcd/command.c.
3858 Added new function silc_server_command_process_timeout.
3860 * Changed NICK_NOTIFY handling in client library to check that
3861 if the client's nickname was changed, so there is no need to
3862 resolve anything from the server.
3864 * Removed error printing from the WHOIS and IDENTIFY commands.
3865 If error occurs then it is ignored silently in the client library.
3866 The application, however, may map the received error to
3867 human readable error string. The application currently maps
3868 the NO_SUCH_NICKNAME error to string.
3870 * Made the command status message public to the application. Moved
3871 them from lib/silcclient/command_reply.c to
3872 lib/silcclient/command_reply.h. The application can map the
3873 received command status to the string with the
3874 silc_client_command_status_message function.
3876 * Added check to the server to check that client's ID is same
3877 as the Source ID in the packet the client sent. They must
3880 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Added dist-bzip hook to the Makefile.am to make bzip2
3883 compressed distributions.
3885 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Server now enforces the maximum length for the nickname and
3888 the channel as protocol specification dictates. 128 bytes for
3889 nickname and 256 bytes for channel name.
3891 * Moved the WHOIS printing to the application. The client libary
3892 does not print out the WHOIS information anymore, the application
3893 must do it. Renamed silc_client_command_reply_whois_print to
3894 the silc_client_command_reply_whois_save.
3896 The client's idle time is also sent to the application now, and
3897 the idle is shown on screen.
3899 * Added silc_client_command_reply_identify_save to save the
3900 received IDENTIFY entries.
3902 * Do not check for channel private keys in message sending and
3903 reception if the channel does not have the PRIVKEY mode set.
3904 Affected file lib/silclient/client_channel.c.
3906 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3909 just surfaced after chaning the JOIN procedure.
3911 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3913 * Added silc_client_get_clients_by_list to get client entries
3914 from Client ID list, that is returned for example by JOIN
3915 and USERS command replies. The application should use this
3916 function for example when JOIN command reply is received to
3917 resolve the clients already on the channel (library does not
3918 do that anymore as USERS command reply is not used in the JOIN
3919 procedure anymore). Affected files lib/silcclient/silcapi.h and
3920 lib/silcclient/idlist.c.
3922 * JOIN command reply and USERS command reply returns now SilcBuffer
3923 pointers instead of unsigned char pointers when returning
3924 the client list and mode list.
3926 * Added <Client ID> argument to the JOIN command reply, mainly
3927 for the server to identify for which client the command was
3928 originally sent. Updated protocol specs accordingly.
3930 * Added SilcDlist private_key pointer to the SilcChannelEntry
3931 in the client to support the channel private keys. Affected
3932 file is lib/silcclient/idlist.h.
3934 * Added SilcChannelPrivateKey argument to the function
3935 silc_client_send_channel_message so that application can choose
3936 to use specific private ke if it wants to. If it is not provided,
3937 the normal channel key is used, unless private keys are set.
3938 In this case the first (key that was added first) is used
3939 as the encryption key.
3941 * Implemented the support for channel private key handling.
3942 Implemented the following functions:
3944 silc_client_add_channel_private_key,
3945 silc_client_del_channel_private_keys,
3946 silc_client_del_channel_private_key,
3947 silc_client_list_channel_private_keys and
3948 silc_client_free_channel_private_keys
3950 Affected file lib/silcclient/client_channel.c.
3952 * Added the support for the private keys in the channel message
3953 sending and encryption and in the message reception and
3954 decryption. Affected funtions are
3955 silc_client_send_channel_message and silc_client_channel_message.
3957 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Added SKE's key verify callback to the client library's
3960 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3962 * Removed the statement that server (or router) must send USERS
3963 command reply when joining to the channel so that the client
3964 knows who are on the channel. Instead, the client list and
3965 client's mode list is now sent in the JOIN command reply to the
3966 client who joined channel. This is better solution.
3968 * Added function silc_server_get_users_on_channel and function
3969 silc_server_save_users_on_channel to the silcd/server.[ch].
3971 * Removed function silc_server_command_send_users from the
3974 * Do not show topic on the client library anymore. The topic is
3975 sent in the command reply notify to the application and the
3976 application must show the topic now.
3978 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added client searching by nickname hash into the IDENTIFY and
3981 WHOIS commands in the server as they were clearly missing from
3982 them. Affected file is silcd/command.c.
3984 * Fixed a bug in private message receiving in the client library.
3985 The remote ID was freed and it wasn't supposed, now it is
3988 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Minor fix to the channel payload; allocate the data area, as it
3991 needs to be of specific length.
3993 * If the key agreement port is zero then the operating
3994 system will define the bound port. Affected files are
3995 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3997 * Added new function silc_channel_payload_decrypt into the file
3998 lib/silccore/silcchannel.[ch].
4000 * Moved the channel message etc, check from silc_packet_decrypt
4001 to applications. The library calls now a generic
4002 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4003 when the packet is either normal or special. This was done to
4004 allow more wide range of checking that was not allowed when
4005 the code was in library. Now applications can do virtually any
4006 checks to the packet and return to the library the decision how
4007 the packet should be processed. Affected files are
4008 lib/silccore/silcpacket.[ch].
4010 Added silc_server_packet_decrypt_check to the server and
4011 silc_client_packet_decrypt_check to the client library.
4013 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4014 to send with specified source and destination information.
4016 * Channel message delivery between routers was broken after the
4017 channel key distribution was fixed earlier. The channel key
4018 was used be to distributed to other routers as well which is not
4019 allowed by the protocol. Now this is fixed and channel keys
4020 really are cell specific and the channel message delivery between
4021 routers comply with the protocol specification.
4023 * Fixed various commands in server to check also the global list
4024 for the channel entry and not just the local list. The affected
4025 file silcd/command.c.
4027 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Added assert()s to buffer formatting and unformatting routines
4030 to assert (if --enable-debug) when error occurs. Affected
4031 file: lib/silcutil/silcbuffmt.c.
4033 * Changed to auto-reconnect to check whether the remote host is
4034 router and register the re-connect timeout if it is. It used
4035 to check that whether we are normal server, but router must do
4036 auto-reconnect with another router as well. Affected file
4039 * Removed the [<key len>] option from CMODE command as the cipher
4040 name decides the key length, nowadays. See the defined ciphers
4041 from the protocol specification.
4043 * Added [<hmac>] option to the CMODE command to define the HMAC
4044 for the channel. Added SILC_CMODE_HMAC channel mode.
4046 * Added [<hmac>] option for the JOIN command so that user can
4047 select which HMAC is used to compute the MACs of the channel
4050 * Added Hmac field to the Channel Message Payload. The integrity
4051 of plaintext channel messages are now protected by computing
4052 MAC of the message and attaching the MAC to the payload. The
4053 MAC is encrypted. Now, it is clear that this causes some
4054 overhead to the size of the packet but rationale for this is that
4055 now the receiver can verify whether the channel message decrypted
4056 correctly and also when private keys are set for the channel the
4057 receiver can decrypt the packet with several keys and check from
4058 the MAC which key decrypted the message correctly.
4060 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4061 lib/silccrypt/silccipher.[ch].
4063 * Added silc_hash_len to return the digest length into the
4064 lib/silcrypt/silchash.[ch].
4066 * Rewrote parts of Silc Channel Payload interface in the
4067 lib/silccore/silcchannel.[ch]. The encode function now also
4068 encrypts the packet and parse function decrypts it.
4070 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Fixed a minor formatting bug in the SKE's key material processing.
4073 It actually might have processed the keys wrong way resulting
4076 * Redefined the mandatory HMAC algorithms and added new algorithms.
4077 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4078 and hmac-md5 truncated to 96 bits. The mandatory is now
4079 hmac-sha1-96. Rest are optional (including the one that used
4080 to be mandatory). Rationale for this is that the truncated HMAC
4081 length is sufficient from security point of view and can actually
4082 make the attack against the HMAC harder. Also, the truncated
4083 HMAC causes less overhead to the packets. See the RFC2104 for
4086 * Added new [hmac] configuration section. The SKE used to use
4087 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4088 is of course wrong. The official names that must be proposed in
4089 the SKE are the ones defined in the protocol specification
4090 (hmac-sha1-96 for example). The user can configure any hmac
4091 using any hash function configured in the [hash] section. At
4092 least, the mandatory must be configured.
4094 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4096 * Added HMAC list to the SKE proposal list. It has now both
4097 hash algorithm list and HMAC list. This makes the protocol
4098 incompatible with previous versions. The SKE now seems to work
4099 the way it is supposed to work, for the first time actually.
4101 * Defined plain Hash algorithms to the protocol specification.
4104 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Implemented support for key agreement packets into the server.
4107 Added functions silc_server_key_agreement and
4108 silc_server_send_key_agreement. Other than these functions,
4109 server has nothing to do with this packet.
4111 * Added support for private message key packets into the server.
4112 Added functions silc_server_private_message_key and
4113 silc_server_send_private_message_key.
4117 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4118 called in the protocol's final callback instead in the END
4119 protocol state. This makes a little more sense and in the same
4120 time in client we can use the same protocol routines for normal
4121 key exchange and to key agreement packet handling as well.
4123 * Added to both client's and server's KE protocol context the
4124 SilcSKEKeyMaterial pointer to save the key material. We will
4125 bring the key material to the protocol's final callback by doing
4126 this. The final callback must free the key material.
4128 * Added SKE's packet_send callback into client's KE protocol
4129 context so that the caller can choose what packet sending function
4130 is used. This way we can use different packet sending when
4131 doing normal SKE when doing key agreement packet handling (in
4132 the key agreement packet handling we do not want to encrypt
4135 * Implemented the responder side of the key agreement routines
4136 in the client. The client can now bind to specified port and
4137 accept incoming key negotiation. The key material is passed
4138 to the application after the protocol is over.
4140 * Implemented the processing of incoming Key Agreement packet
4141 in the client. Added function silc_client_key_agreement to
4144 * Implemented the intiator side of the key agreement routines
4145 in the client. The client can now initiate key agreement with
4146 another remote client. The key material is passed to the
4147 application after the protocol is over.
4149 * Created client_keyagr.c to include all the key agreement
4152 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4153 SILC_TASK_CALLBACK except that it is not static.
4155 * Created client_notify.c and moved the Notify packet handling
4156 from the client.[ch] into that file.
4158 * Created client_prvmsg.c and moved all private message and
4159 private message key routines from the client.[ch] into that file.
4161 * Create client_channel.c and moved all channel message and
4162 channel private key routines from the client.[ch] into that file.
4164 * Changed silc_client_get_client_by_id_resolve to resolve with
4165 WHOIS command instead of IDENTIFY command, in the file
4166 lib/silclient/idlist.c.
4168 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Implemented the SKE's responder side to the Client library.
4172 * When FAILURE is received to the protocol do not trust it
4173 blindly. Register a timeout to wait whether the remote closes
4174 the connection as it should do it, only after that process the
4175 actual failure. This was changed to both client and server.
4177 * Added client_internal.h to include some of the structures
4178 there instead of client.h in lib/silcclient/.
4180 * Added function silc_task_unregister_by_callback to unregister
4181 timeouts by the callback function.
4183 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Some "Incomplete WHOIS info" errors has been appearing on the
4186 log files. Took away the entry->userinfo check from WHOIS
4187 reply sending. The entry->userinfo is now " " if client did not
4188 provide one. I thought this was fixed earlier but something
4189 is wrong still. Let's see if the error still appears.
4191 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Fixed a minor bug in the login when the channel key is
4194 re-generated in the server. It used to generate the key in
4195 wrong order and thus caused problems in the channel traffic.
4197 * Fixed a minor bug in channel key distsribution after
4198 KICK command. The key was not sent to the router even though
4201 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Added silc_ske_process_key_material_data as generic routine
4204 to process any key material as the SILC protocol dictates. The
4205 function is used by the actual SKE library but can be used by
4206 applications as well. This relates to the private message keys
4207 and the channel private keys since they must be processed the
4208 same way the normal SILC session keys. The protocol dictates
4209 this. Affected files: lib/silcske/silcske.[ch].
4211 Added also silc_ske_free_key_material to free the
4212 SilcSKEKeyMaterial structure.
4214 * Defined silc_cipher_set_key function to set the key for
4215 cipher without using the object's method function. The affected
4216 files: lib/silccrypt/silccipher.[ch].
4218 * Implemented silc silc_client_add_private_message_key,
4219 silc_client_add_private_message_key_ske,
4220 silc_client_del_private_message_key,
4221 silc_client_list_private_message_keys and
4222 silc_client_free_private_message_keys functions in the
4225 Added functions silc_client_send_private_message_key to send
4226 the Private Message Key payload and silc_client_private_message_key
4227 to handle incoming Private Message Key payload.
4229 * Added Cipher field to the Private Message Key payload to set
4230 the cipher to be used. If ignored, the default cipher defined
4231 in the SILC protocol (aes-256-cbc) is used.
4233 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Removed lib/silcclient/ops.h file.
4237 Redefined parts of the SILC Client Library API. Created new
4238 file silcapi.h that deprecates the ops.h file and defines the
4239 published Client Library API. Defined also private message key
4240 API and channel private key API into the file.
4242 This is the file that the application must include from the
4243 SILC Client Library. Other files need not be included by
4244 the application anymore.
4246 * Added new key_agreement client operation callback and also
4247 defined the Key Agreement library API for the application.
4249 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4252 is used by clients to request key negotiation between another
4253 client in the SILC network. If the negotiation is started it
4254 is performed using the SKE protocol. The result of the
4255 negotiation, the secret key material, can be used for example
4256 as private message key.
4258 Implemented the Key Agreement payload into the files
4259 lib/silccore/silauth.[ch].
4261 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Redefined ciphers for the SILC protocol. Added some new ciphers
4264 and defined the key lengths for the algorithms. Changed the
4265 code accordingly. The default key length is now 256 bits.
4267 * Fixed SKE key distribution function silc_ske_process_key_material
4268 when the key length is more than 128 bits. The default key
4269 length in SILC is now 256 bits.
4271 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4272 to indicate unsupported algorithm.
4274 * Renamed rijndael.c to aes.c and all functions as well.
4276 * Fixed a long standing channel key setting bug in client library.
4277 Weird that it has never surfaced before.
4279 * Fixed bug in channel deletion. If the entire channel is removed
4280 then it must also delete the references of the channel entry
4281 from the client's channel list as the client's channel entry and
4282 the channel's client entry share same memory.
4284 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Implemented CONNECT and SHUTDOWN commands in the client.
4288 * Implemented CLOSE command to the client.
4290 * Added the function silc_idlist_find_server_by_name into the
4291 files silcd/idlist.[ch].
4293 Added the function silc_idlist_find_server_by_conn into the
4294 files silcd/idlist.[ch].
4296 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * DIE command was renamed to SHUTDOWN. Updated the both code
4301 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4302 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4304 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4307 * Added function silc_server_create_connection function to create
4308 connection to remote router. My server implementation actually
4309 does not allow router to connect to normal server (it expects
4310 that normal server always initiates the connection to the router)
4311 so the CONNECT command is only good for connecting to another
4314 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4317 or some other client was kicked from the channel.
4319 Implemented the handling of the notify type to both client
4322 Implemented silc_server_send_notify_kicked to send the KICKED
4323 notify. It is used to send it to the server's primary router.
4325 * Implemented the KICK command into server and client.
4327 * Added `query' argument to the silc_idlist_get_client function
4328 to indicate whether to query the client from server or not if
4331 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4332 to indicate that the client is not channel founder.
4336 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Removed the rng context from SilcPacketContext structure and
4339 changed that the packet routine uses the Global RNG API.
4341 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Added support for quit message that client can "leave" on the
4344 channel when it quits the SILC. It is ditributed inside the
4345 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4347 Added silc_server_free_client_data that will take the
4348 signoff message as argument.
4350 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4352 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Updated parts of the protocol specification to keep it up
4357 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4360 payloads in one packet.
4362 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4363 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4364 use now the new List flag.
4366 * Also deprecated the following packet types: REPLACE_ID,
4367 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4369 * Added list support for Notify packet in server.
4371 * Added silc_server_send_notify_channel_change to send the
4372 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4373 the silc_server_send_replace_id.
4375 * Added silc_server_send_notify_nick_change to send the
4376 NICK_CHANGE notify type. Deprecates the function
4377 silc_server_send_replace_id.
4379 * Added silc_server_send_notify_join to send the JOIN notify type.
4380 Deprecates the function silc_server_send_new_channel_user.
4382 * Added silc_server_send_notify_leave to send LEAVE notify type.
4383 Deprecates the function silc_server_send_remove_channel_user.
4385 * Added silc_server_send_notify_cmode and
4386 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4387 types. Deprecates the silc_server_send_set_mode function.
4389 * Added SERVER_SIGNOFF notify type to indicate that server has
4390 quit. This means that all clients on the channel from that
4391 server will drop. This can be also used when netsplit happens.
4393 Deprecated REMOVE_ID packet type since it is not needed anymore
4396 Added silc_server_send_notify_server_signoff to send the
4397 SERVER_SIGNOFF notify type. Deprecates the function
4398 silc_server_send_remove_id.
4400 Added also silc_server_send_notify_signoff to send the
4401 SIGNOFF notify type.
4403 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4404 SILC protocol from this day on. Changed the protocol
4405 specification as well.
4407 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4408 notify type. It is used between routers to notify about
4409 topic changes on a channel.
4411 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4414 * Partly updated the protocol specification to comply with the
4415 changes now made. It is still though a bit outdated.
4417 * The JOIN notify type now takes one extra argument <Channel ID>.
4418 The packet used to be destined to the channel but now the
4419 JOIN type may be sent as list thus it is impossible to
4420 destine it to any specific channel. By adding this argument
4421 it is again possible.
4423 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Added CREDITS file. The CHANGES and CREDITS file will appear
4426 in the distribution as well.
4428 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4431 types in the server's silcd/packet_receive.c.
4433 * Implemented CMODE and CUMODE to work in router environment.
4435 * Fixed minor encoding and decoding buglet from the
4436 lib/silccore/silcmode.c.
4438 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4441 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4443 * Changed all SilcConfigServer* and silc_config_server* to
4444 SilcServerConfig* and silc_server_config*, respectively.
4447 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Associated the ID (client or server ID) to the Authentication
4450 Payload to avoid any possibility of forging. Updated the
4451 protocol specification and the code accordingly.
4453 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * The RSA key length is now save to the RsaKey context in the
4456 key generation process in lib/silccrypt/rsa.c. The key length
4457 is now used to figure out the maximum size of the block allowed
4458 to be encrypted/signed.
4460 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4461 is equivalent to the silc_mp_mp2bin but does not allocate any
4464 * Changed silc_mp_mp2bin API to take length argument. If it is
4465 non-zero then the buffer is allocated that large. If zero, then
4466 the size is approximated using silc_mp_sizeinbase, which however
4469 * Created Global RNG API which is global RNG that application can
4470 initialize. After initializing, any routine anywhere in the
4471 code (including library) can use RNG without allocating a new
4472 RNG object. This was done to allow this sort of use of the
4473 RNG in code that has no chance to allocate RNG object. All
4474 applications currently allocate this and many routines in the
4475 library use this. Affected file lib/silccrypt/silcrng.[ch].
4477 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4478 it to use the Global RNG API.
4480 * Defined Authentication Payload into protocol specification that
4481 is used during SILC session to authenticate entities. It is
4482 used for example by client to authenticate itself to the server
4483 to obtain server operator privileges.
4485 Implemented this payload into the lib/silccore/silcauth.[ch].
4486 Implemented also routines for public key based authentication
4487 as the new protocol specification dictates.
4489 Moved definitions of different authentication methods from
4490 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4492 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4493 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4494 silc_pkcs_verify_with_hash functions into the file
4495 lib/silccrypt/silcpkcs.[ch].
4497 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * The client entry's userinfo pointer must be always valid.
4500 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4501 will fail since it requires the userinfo. Now, the userinfo
4502 is allocated as "" if actual userinfo does not exist. Actually,
4503 it must exist and it is totally Ok to drop client connections
4504 that does not announce the userinfo. However, we will make
4505 this workaround for now.
4507 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4508 to return the remote port by socket.
4510 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4513 SILC_SERVER_PENDING_EXEC and added an new macro
4514 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4515 data or when error occurs while processing the pending command.
4517 Added new argument `destructor' into silc_server_command_pending
4518 and to the SilcServerCommandPending object. This destructor is
4519 now called after calling the pending callback or if error occurs
4520 immediately. If error occurs the actual pending callback won't
4521 be called at all - only the destructor. The destructor may be
4522 NULL if destructor is not needed.
4524 All this applies for client library code as well. Similar
4525 changes were made there as well for the pending commands.
4527 In the client, the application must now allocate the
4528 SilcClientCommandContext with the silc_client_command_alloc
4531 * Added reference counter to the SilcServerCommandContext. Added
4532 function silc_server_command_alloc and silc_server_command_dup
4535 Same type of functions added to the client library for the same
4538 * Removed the cmd_ident from IDListData away since it is now
4539 global for all connections. It is the command identifier used
4540 in command sending and with pending commands. The affected file
4543 * Added reference counter to the SilcSocketConnection objecet to
4544 indicate the usage count of the object. The object won't be
4545 freed untill the reference counter hits zero. Currently only
4546 server uses this, and client ignores it. The client must be
4547 set to use this too later. The affected files are
4548 lib/silccore/silcsockconn.[ch]. Added also the function
4549 silc_socket_dup to increase the reference counter.
4551 This was mainly added because it is possible that the socket
4552 is removed underneath of pending command or other async
4553 operation. Now it won't be free'd and proper DISCONNECTING
4554 flags, etc. can be set to avoid sending data to connection that
4555 is not valid anymore.
4557 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4558 the connection. After that it sets SILC_SET_DISCONNECTED.
4559 It is, however, possible that the socket data is not still freed.
4560 The silc_server_packet_process now checks that data is not
4561 read or written to connection that is DISCONNECTED. The socket
4562 get's freed when the reference counter hits zero.
4564 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Changed the client operation API: channel_message operation's
4567 `sender' is now the client entry of the sender, not the nickname
4568 and the `channel' is the channel entry, not the channel name.
4570 In the private_message operation the `sender' is now also the
4571 client entry of the sender not the nickname.
4573 Affected file is lib/silcclient/ops.h and all applications
4574 using the client operations.
4576 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Moved the calling of ops->connect() from connect_to_server_final
4579 into receive_new_id functin since that is the point when the
4580 client is actually allowed to send traffic to network. The
4581 affected file is lib/silcclient/client.c.
4583 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4586 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4587 (if needs broadcasting) instead of broadcasting the packets one
4588 by one which would make a burst in the network traffic.
4590 * Added `broadcast' argument to the functions in silcd/server.[ch]
4591 silc_server_create_new_channel[_with_id] to indicate whether
4592 to send New Channel packet to primary router.
4594 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Added new function into the silcd/server.[ch] files:
4597 silc_server_create_new_channel_with_id to create new channel with
4598 already existing Channel ID.
4600 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4601 lib/silccore/silcpacket.h. This packet is used t send list of
4602 Set Mode payloads inside one packet. Server uses this to set
4603 the modes for the channels and clients on those channels, that it
4604 announced to the router when it connected to it. The protocol
4605 specification has been updated accordingly.
4607 * The silc_server_new_channel did not handle the packet coming
4608 from normal server as it normally does not send that. However,
4609 when it announces its channels it does send it. Implemented
4610 the support for that.
4612 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4613 into the file lib/silccore/id.h.
4615 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Fixed memory leaks in the functions silc_idlist_del_client,
4618 silc_idlist_del_channel and silc_idlist_del_server in the file
4619 silcd/idlist.c. All of those leaked like a sieve.
4621 * Fixed some small memory leaks in the client's function
4622 silc_client_notify_by_server.
4624 * Added functions into silcd/server.c: silc_server_announce_clients,
4625 silc_server_announce_channels and silc_server_announce_server.
4626 These functions are used by normal and router server to announce
4627 to its primary router about clients, channels and servers (when
4628 router) that we own. This is done after we've connected to the
4631 These functions effectively implements the following packet types:
4632 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4633 and SILC_PACKET_NEW_ID_LIST.
4635 * Added new functions into the silcd/packet_receive.[ch]:
4636 silc_server_new_id_list, silc_server_new_channel_list and
4637 silc_server_new_channel_user_list to handle the incoming
4638 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4640 * Added support of changing Channel ID in the function
4641 silc_server_replace_id. If the server that announces a channel
4642 to the router already exists in the router (with same name but
4643 with different Channel ID), router is responsible to send
4644 Replace ID packet to the server and force the server to change
4645 the Channel ID to the one router has.
4647 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4648 client that the Channel ID has been changed by the router. The
4649 normal server sends this to the client. Client must start using
4650 the new Channel ID as the channel's ID.
4652 Implemented handling of this new type into lib/silcclient/client.c
4653 into the function silc_client_notify_by_server.
4655 * Added new function silc_idlist_replace_channel_id into the files
4656 silcd/idlist.[ch] to replace the Channel ID.
4658 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Call silc_server_command_identify_check always when processing
4661 the IDENTIFY command in silcd/command.c
4663 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4666 send keepalive packets. The packet can be sent by clients,
4667 servers and routers.
4669 Added function silc_socket_set_heartbeat into the file
4670 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4671 If not set, the heartbeat is not performed. The actual
4672 heartbeat is implemented in the low level socket connection
4673 library. However, application is responsible of actually
4676 Added silc_server_send_heartbeat to send the actual heartbeat
4677 packet into silcd/packet_send.[ch]. Server now performs
4678 keepalive with all connections.
4680 * Added silc_task_get_first function into lib/silcutil/silctask.c
4681 to return the timeout task with shortest timeout. There was a bug
4682 in task unregistration that caused problems. TODO has been
4683 updated to include that task system must be rewritten.
4685 * The client library will now resolve the client information when
4686 receiving JOIN notify from server for client that we know but
4687 have incomplete information.
4689 * Rewrote parts of silc_server_remove_from_channels and
4690 silc_server_remove_from_one_channel as they did not remove the
4691 channel in some circumstances even though they should've.
4693 * Encryption problem encountered in server:
4695 The LEAVE command used to send the Channel Key packet to the
4696 router immediately after generating it. However, the code
4697 had earlier sent Remove Channel user packet but not immediately,
4698 ie. it was put to queue. The order of packets in the router
4699 was that Channel Key packet was first and Remove Channel User
4700 packet was second, even though they were encrypted in the
4701 reverse order. For this reason, MAC check failed. Now, this
4702 is fixed by not sending the Channel Key packet immediately but
4703 putting it to queue. However, this is more fundamental problem:
4704 packets that are in queue should actually not be encrypted
4705 because packets that are sent immediately gets encrypted
4706 actually with wrong IV (and thus MAC check fails). So, packets
4707 that are in queue should be encrypted when they are sent to
4708 the wire and not when they put to the queue.
4710 However, the problem is that the current system has not been
4711 designed to work that way. Instead, the packet is encrypted
4712 as soon as possible and left to the queue. The queue is then
4713 just purged into wire. There won't be any fixes for this
4714 any time soon. So, the current semantic for packet sending
4717 o If you send packet to remote host and do not force the send
4718 (the packet will be in queue) then all subsequent packets to the
4719 same remote host must also be put to the queue. Only after the
4720 queue has been purged is it safe again to force the packet
4723 o If you send all packets immediately then it safe to send
4724 any of subsequent packets through the queue, however, after
4725 the first packet is put to queue then any subsequent packets
4726 must also be put to the queue.
4728 Follow these rules and everything works fine.
4730 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Added new function silc_server_remove_clients_by_server to
4733 remove all client entries from ID list when the server connection
4734 is lost. In this case it is also important to invalidate all
4735 client entires as they hold the invalid server entry. This
4736 fixes fatal bug when server has lost connection and will reconnect
4739 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Made some sanity checks to silc_server_daemonise like to check
4742 whether the requested user and group actually exists.
4744 * Added sanity check to SKE's silc_ske_responder_finish to check
4745 that the public and private key actually is valid.
4747 * Invalidate the client's nickname when receiving Replace ID
4748 packet and the Client ID is being replaced. This means that the
4749 server will query the nickname if someone needs it (client)
4752 * Sort the ID Cache in client library when the ID Cache data
4753 has changed (needs sorting).
4755 * Do not allow for SILC client to create several connections to
4756 several servers. The client does not support windows right now
4757 and generating multiple connections causes weird behaviour.
4759 Irssi-silc client does support windows and can handle several
4760 connections without problems, see: www.irssi.org and SILC plugin.
4762 * Fixed some places where client was added to the IDList. The
4763 rule of thumb is following (in order to get everything right):
4764 If the client is directly connected local client then the
4765 `connection' argument must be set and `router' argument must be
4766 NULL to silc_idlist_add_client function. If the client is not
4767 directly connected client then the `router' argument must
4768 bet set and the `connection' argument must be NULL to the
4769 silc_idlist_add_client function.
4771 * The funtion silc_server_packet_send_local_channel actually did
4772 not check whether the client was locally connected or not. It
4773 does that now. Fixed a bug related to LEAVE command.
4775 * Fixed Remove Channel User payload parsing bug in server's
4776 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4778 * The server's silc_server_save_channel_key now checks also the
4779 global ID list for the channel as it might not be in the local
4780 list. Fixed a bug related to LEAVE command.
4782 * Is this the end of the [<unknown>] buglet that has been lurking
4783 around for a long time? A little for loop fix in server's
4784 silc_server_command_whois_parse that is used by both IDENTIFY
4785 and WHOIS command. At least, this was a clear bug and a cause
4786 of one type of [<unknown>] buglet.
4788 * WHOIS and IDENTIFY commands call the function
4789 silc_server_command_[whois/identify]_check function even if
4790 we are not router server.
4792 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Added --with-gmp configuration option. If set the GMP
4795 is always compiled in the SILC source tree. If not set then
4796 it is checked whether the system has the GMP3 installed. If
4797 it has then the GMP won't be compiled (the system's headers
4798 and library is used), if it doesn't have it then the GMP is
4799 compiled in the SILC source tree.
4801 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Changed RSA private exponent generation to what PKCS #1
4804 suggests. We try to find the smallest possible d by doing
4805 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4806 not security fix but optimization.
4808 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added new config entry [Identity] to fork the server and run
4811 it as specific user and group. A patch from Bostik.
4813 * Imported Dotconf configuration library into lib/dotconf.
4814 This will be used to create the SILC configuration files later.
4815 It will appear in the distsribution after this commit.
4817 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * A big code auditing weekend happening. Auditing code for
4820 obvious mistakes, bugs and errors. Also, removing any code
4823 Removed files for being obsolete:
4825 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4826 inline in the file lib/silcutil/silcbuffer.h)
4828 o lib/silcutil/silcbufutil.c (the header has inline versions)
4830 Changed code to fix possible error conditions:
4832 o The buffer formatting routines now check that the destination
4833 buffer really has enough space to add the data. This applies for
4834 both buffer formatting and unformatting
4835 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4836 unformatting was changed to accomodate following rules:
4837 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4838 sent to the function while XXX_*STRING will not allocate or copy
4839 the data into the buffer. Instead it sets the pointer from the
4840 buffer into the pointer sent as argument (XXX_*STRING used to
4841 require that the pointer must be allocated already). This change
4842 makes this whole thing a bit more consistent and more optimized
4843 (note that the data returned in the unformatting with XXX_*STRING
4844 must not be freed now). The routines return now -1 on error.
4846 o Tried to find all code that use buffer_format and buffer_unformat
4847 and added return value checking to prevent formatting and
4848 especially unformatting errors and possible subsequent fatal
4851 o Changed ske->x and ske->KEY to mallocated pointers in
4852 lib/silcske/silcske.h. Fixed possible data and memory leak.
4854 o Added return value checking to all *_parse* functions. Fixed
4855 many memory leaks as well.
4857 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4858 so that buffer overflows would not happen. All code now also
4859 checks the return value as it can fail.
4861 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added reconnection support to server if the normal server looses
4864 its connection to the router (for example if router is rebooted).
4865 The server performs normal reconnection strategy implemented
4866 to the server. Affected file silcd/server.c.
4868 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Added new packet type SILC_PACKET_SET_MODE that is used to
4871 distribute the information about changed modes (for clients,
4872 channels and clients channel modes) to all routers in the
4873 network. Updated the protocol specification accordingly.
4875 Added functions into silcd/packet_send.c and
4876 silcd/packet_receive.c: silc_server_send_set_mode,
4877 silc_server_set_mode.
4879 Added new files silcmode.[ch] into lib/silccore that implements
4880 the encoding and decoding of Set Mode Payload. Added new type
4881 SilcSetModePayload. Moved the definitions of different modes
4882 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4884 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Oops, a little mistake in server's connection authentication
4887 protocol. The protocol is not ended with FAILURE but with
4888 SUCCESS if the authentication is Ok. :) Affected file is
4891 * Implemented NICK_CHANGE notify handling in server in the file
4892 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4893 the local clients on the channel. After the changing nickname
4894 in router environment snhould work and the [<unknown>] nickname
4895 should appear no more.
4897 The silc_server_replace_id function that receives the Replace ID
4898 payload now sends the NICK_CHANGE notify type also in the file
4899 silcd/packet_receive.c
4901 * Changed WHOIS and IDENTIFY command to support the maximum amount
4902 of arguments defined in protocol specs (3328 arguments). This
4903 fixed a bug that caused problems when there were more than three
4906 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Added extra parameter, command identifier, to the
4909 silc_client_send_command so that explicit command identifier
4912 Changed that ID list routines uses specific command identifier
4913 when sending WHOIS/IDENTIFY requests to the server so that they
4914 can be identified when the reply comes back.
4916 Affected files lib/silcclient/command.[ch],
4917 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4919 * Added `sender' argument to silc_server_packet_send_to_channel
4920 to indicaet the sender who originally sent the packet to us
4921 that we are now re-sending. Ignored if NULL. Affected file
4922 silcd/packet_send.[ch].
4924 * Added some server statistics support in silcd/server_internal.h
4925 SilcServerStatistics structure and around the server code. Also
4926 send some nice statistics information when client is connecting
4929 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Fixed channel ID decoding in server's JOIN command reply in
4932 silcd/command_reply.c
4934 * Fixed braodcasting of replace ID payload to not to send it if
4935 we are standalone server in silcd/packet_receive.c.
4937 * Fixed all channel message sending routines to not to send
4938 packets to clients that has router set, since they are routed
4939 separately in the same function earlier. Affects file
4940 silcd/packet_send.c and all channel packet sending functions.
4942 * In USERS reply, res_argv[i] are not allocated, the table
4943 is allocated. Thus changed that free the table, not its
4946 * In server's whois_check and identify_check if the client is
4947 locally connected do not send any WHOIS commands - they are not
4950 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Fixed some minor bugs in client when sending WHOIS command. The
4953 arguments was in wrong order.
4955 * Removed statis function add_to_channel from server in
4956 silcd/command.c that was previously used with the joining but
4959 * Tested USERS command in router environment successfully with two
4960 routers, two servers and two clients.
4962 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Reorganized the USERS command and command reply in client library
4965 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4966 When the command is given by user we register a pending command
4967 callback that will reprocess the command after the reply has been
4968 received from the server. When reprocessing the packet we then
4969 display the information. Thus, the USERS information is displayed
4970 now in the command callback instead of in the command reply
4971 callback. The processing of the command is same as previously
4972 when server has sent the command reply in the JOINing process.
4974 * Added to USERS command in silcd/command_reply.c to join the client,
4975 we didn't use to know about, to the channel after we've created
4976 a client entry for it. Also, for clienet we did know already still
4977 check whether it is on the channel or not and add it if not.
4979 * Removed silc_server_command_join_notify as the function and its
4982 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Changed the client's pending command handling to the same as the
4985 server's pending command handling. It is also now possible to
4986 execute command reply functions from other command reply
4987 function as the function callbacks for commands and command
4988 replies are one and same. The pending commands are not static
4989 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4990 in client connection context. Thus, pending commands are server
4991 connection specific as it is convenient.
4993 Changed the function silc_client_command_pending and
4994 silc_client_command_pending_del and added new function
4995 silc_client_command_pending_check. Removed the
4996 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4999 * Added cmd_ident, current command identifier, to the client
5000 connection context in lib/silcclient/client.h to keep track on
5001 command identifiers used in command sending. Client's command reply
5002 function handling now supports the mandatory command identifiers.
5004 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5005 funtions in client to fully support pending command callbacks.
5007 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5008 as one of the arguments to the application in the command reply
5011 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5012 before first releasing SILC but came back. Now it is removed again
5013 and should come back nomore. The FORWARDED flag was used only
5014 by the JOINing procedure by forwarding the command packet to router.
5015 Now, the JOINing procedure has been changed to more generic (due
5016 to various router environment issues) and FORWARDED is not needed
5017 anymore for anything. The protocol specification is yet to be
5020 Now, removed silc_server_packet_forward from server and the flag
5021 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5023 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Renamed NAMES command to USERS command. The NAMES was named that
5026 due to historical reasons. Now it is renamed. Also, rewrote
5027 parts of the USERS command. The nickname list is not sent anymore
5028 by the server. Only Client ID and mode lists are sent in the USERS
5029 command. Changed this also to the protocol specification.
5031 The client now resolves the names and stuff after it receives
5032 the USERS list from the server when joining to the channel.
5034 * WHOIS and IDENTIFY commands has been changed to support multiple
5035 Client ID's per command. One can now search for multiple users
5036 in the network by sending only one WHOIS or IDENTIFY command.
5037 Changed the code and the protocol specifications.
5039 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5040 uses silc_server_command_whois_parse to parse the request. */
5042 * If normal server, do not parse the WHOIS and IDENTIFY requests
5043 before sending it to the router. Saves some time.
5045 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed JOIN command on client library. Wrong number of arguments
5048 used to crash the client.
5050 * Added silc_server_channel_has_global function to check whether
5051 channel has global users or not.
5053 * Added silc_server_channel_has_local function to check whether channel
5054 has locally connected clients on the channel.
5056 * The silc_server_remove_from_one_channel now checks whether the
5057 channel has global users or not after given client was removed from
5058 the channel. It also checks whether the channel has local clients
5059 on the channel anymore. If it does not have then the channel entry
5060 is removed as it is not needed anymore.
5062 * The silc_server_notify now checks on JOIN notify whether the joining
5063 client is one of locally connected or global. If it is global then
5064 the channel has now global users on the channel and that is marked
5065 to the channel entry. Also, it now saves the global client to
5066 global list who is joining and JOINs it to the channel. This is
5067 for normal server, that is.
5069 Changed silc_server_send_notify_on_channel,
5070 silc_server_packet_relay_to_channel and
5071 silc_server_packet_send_to_channel check if we are normal server
5072 and client has router set (ie. global client) do not send the
5073 message to that client, as it is already routed to our router.
5075 * Implemented LEAVE notify type handling in silc_server_notify
5078 * Tested LEAVE command in router environment successfully. Tested
5079 with two routers, two servers and two clients.
5083 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5085 * Implemented SIGNOFF notify type handling in silc_server_notify
5088 * silc_server_remove_id now removes the client entry from all channels
5089 it has joined and thusly sends SIGNOFF notify type.
5091 * Rewrote the NAMES list generation in server by removing two excess
5092 loops. The lists are created now inside one loop.
5094 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * silc_server_remove_channel_user checks now also global list
5097 for channel and client.
5099 * silc_server_new_channel_user checks now both local and global
5100 list for channel and client. Fixed a bug in client id decoding.
5101 Used to decode wrong buffer.
5103 * silc_server_channel_message checks now both local and global
5104 list for channel entry.
5106 * Tested channel joining (hence JOIN) in router environment
5107 successfully. Tested with two routers, two servers and two
5110 * Tested channel message sending in router environment successfully.
5112 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Added silc_server_save_channel_key into server.[ch] to save the
5115 received channel key in Channel Key payload processing. It is
5116 also used in JOIN command reply handling.
5118 Equivalent function silc_client_save_channel_key added into
5119 client.[ch] into client library.
5121 * Changed JOIN command reply to send information whether the channel
5122 was created or not (is existing already) and the channel key
5123 payload. Changed protocol specs accordingly.
5125 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5126 the request was sent by ID and not by nickname. Crashed on
5129 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5132 now correctly save the received data.
5134 * silc_server_free_sock_user_data now notifies routers in the
5135 network about entities leaving the network.
5137 At the same time implemented functions silc_server_remove_id
5138 and silc_server_send_remove_id to receive and send REMOVE_ID
5139 packets. The packet is used to notify routers in the network
5140 about leaving entities. The ID removed will become invalid in
5143 * Added function silc_idlist_del_server into server. Removes and
5144 free's server entry from ID list.
5146 * silc_server_private_message function now checks, if we are router,
5147 that the destination ID really is valid ID, naturally.
5149 * In router when NEW_ID packet is received (for new client) the
5150 hash of the Client ID is saved in the ID Cache but the
5151 client->nickname is set to NULL, instead of putting the hash
5154 IDENTIFY command now also checks that client->nickname must be
5155 valid. If it is not if will request the data from the server who
5156 owns the client. Added new function
5157 silc_server_command_identify_check.
5159 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5160 to set the command to already allocated Command Payload.
5162 * Tested private message sending in router environment with two
5163 routers, two servers and two clients. Fixed minor bugs and now
5166 * Fixed segfault from client's NAMES command. Used to crash if
5169 * Forwarded packets must not be routed even if it is not destined
5170 to the receiver. Changed server code comply with this.
5172 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Added `require_reverse_mapping' boolean value to ServerParams
5175 structure. If TRUE (not default) the server will require that
5176 the connecting host has fully qualified domain name.
5178 If the reverse mapping is not required and hostname could not be
5179 found the IP address is used as hostname.
5181 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Implemented version string checking to both client and server.
5184 The check is incomplete currently due to the abnormal version
5185 strings used in development version of SILC.
5187 * Changed all command functions in server to use the new
5190 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Changed char *data to unsigned char *data in ID Cache system to
5193 support binary data as ID Cache data. Changed code to support
5194 binary data in lib/silccore/idcache.c.
5196 * Renamed silc_server_packet_relay_command_reply to
5197 silc_server_command_reply as it is normal packet receiving
5198 function. Rewrote the function to accept command replys for
5199 servers and not only for clients.
5201 * Mark remote router always as registered server if we are connecting
5202 to it. Otherwise, commands sent by the router to us are ignored.
5204 * All ID List find routines now returns the ID Cache Entry pointer
5205 as well if requested.
5207 * WHOIS command works now in router environment, tested with two
5208 routers, two servers and two clients.
5210 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5211 in router environment (as it is almost equivalent to WHOIS) but
5212 hasn't been tested thoroughly. Added new functions:
5214 silc_server_command_identify_parse
5215 silc_server_command_identify_send_reply
5216 silc_server_command_identify_from_client
5217 silc_server_command_identify_from_server
5219 * Disabled route cache adding because adding two different ID's with
5220 same IP replaces the old cache entry thus giving wrong route.
5221 The entry->router->connection is always the fastest route anyway
5222 so route cache may not be needed. Of course, new routes maybe
5223 established after receiving the ID when the entry->router->connection
5224 might not be anymore the most optimal.
5226 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Add route cache for received ID for fast routing.
5230 * Added silc_server_packet_route to route received packet on router
5231 that is not destined to us.
5233 * Renamed silc_server_get_route to silc_server_route_get.
5235 * Added id_string and id_string_len fields into SilcServer to
5236 include encoded ServerID for fast comparing without excess
5237 encoding of the ID's.
5239 * Cleaned up WHOIS command on server side. Added following static
5242 silc_server_command_whois_parse
5243 silc_server_command_whois_check
5244 silc_server_command_whois_send_reply
5245 silc_server_command_whois_from_client
5246 silc_server_command_whois_from_server
5248 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5249 arguments in command replies. All command functions should be
5250 updated to use this macro.
5252 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Minor typo fixes on command reply handling on server.
5256 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added silc_server_command_add_to_channel internal routine to add
5259 the client to the channel after router has created the channel and
5260 sent command reply to the server.
5262 * Added generic silc_server_send_command to send any command from
5265 * Use static buffer with ID rendering instead of duplicating data.
5267 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Fixed a channel user mode bug when joining to a channel server gave
5270 everybody channel founder rights, oops.
5272 * We mark ourselves as the router of the incoming server connection
5273 if we are router ourselves. This way we can check in some packet
5274 sending functions whether it is locally connected server. For
5275 incoming router connections we put NULL.
5277 * For router sending packets locally means now always sending the
5278 packet cell wide; to local clients and local servers. For normal
5279 server sending packet locally means sending it to only local
5282 * Fixed the JOIN command to really work in router environment. If the
5283 channel is created it is always created by the router. Router is
5284 also responsible of making the initial joining to the channel,
5285 sending JOIN notify to the sending server and distributing
5286 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5287 does not exist server doesn't do anything else but forward the
5288 command to the router which performs everything.
5290 * Added silc_server_send_channel_key function to send the Channel Key
5293 * Added silc_server_create_channel_key to create new channel key. The
5294 channel key is now re-generated everytime someone joins or leaves
5295 a channel, as protocol dictates. Note: channel->key_len is the
5298 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5301 packet_receive.[ch] to separate packet sending and receiving
5302 routines. The server.[ch] now includes everything else including
5303 actual packet processing (writing and reading data) and other
5306 Renamed silc_server_private_message_send_internal to
5307 silc_server_send_private_message. The routine is still though
5308 used only to relay private messages as server does not send
5309 private messages itself.
5311 Renamed silc_server_new_channel to silc_server_create_new_channel
5312 and added new function sicl_server_new_channel that handles the
5313 incoming New Channel packet. Added also new sending function
5314 silc_server_send_new_channel to send New Channel Payload.
5316 * Added new function silc_server_notify to process incoming notify
5317 packet to the server/router. Server may then relay the notify
5318 to clients if needed.
5320 * Added new function silc_server_new_channel_user to process incoming
5321 New Channel User packet. Router will redistribute the packet and
5322 send JOIN notify to its local clients and locally connected servers
5323 if needed. Normal server will send JOIN notify to its local client
5324 on same channel when received this packet. Added also corresponding
5325 sending function silc_server_send_new_channel_user to sent the
5328 * Added boolean route argument to send_notif_to_channel and
5329 packet_send_to_channel functions to attempt to route the packet
5330 if it is TRUE and send only locally if it is FALSE.
5332 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * silc_server_replace_id now broadcasts the received replace ID
5335 packet if it is not broadcast packet already. The router must
5336 broadcast to inform other routers about changed ID.
5338 * Added backpointer to server's router into SilcServer context in
5339 silcd/server_internal.h.
5341 * Fixed silc_server_packet_broadcast to send correct broadcast
5344 * The channel key is now distributed to the local client as soon
5345 as it is received from the router (in router environment) so that
5346 no other packet may be sent for the channel until client has
5349 * silc_server_remove_channel_user now broadcasts the received
5350 Remove Channel User packet if it is not broadcast packet already.
5351 The router must broadcast to inform other routers about removed
5354 * Added users field into SilcPacketContext that is a reference count
5355 of the context. One can increase the reference count by calling
5356 silc_packet_context_dup which is now changed to just increase the
5357 reference count instead of duplicating the data. The reference
5358 count is decresed by calling silc_packet_context_free that will
5359 free the data after the reference count hits zero.
5361 For now on the packet context and everything allocated into it
5362 (including the raw packet from network) must be freed by calling
5363 the new silc_packet_context_free function. Added also new function
5364 silc_packet_context_alloc that must be used now to allocate the
5365 context. This also means that if a routine is asynchronous from
5366 silc_[client/server]_packet_parse_type the packet context must
5367 be duplicated by calling silc_packet_context_dup. Otherwise it
5368 gets free'd after silc_[client/server]_packet_parse_type returns.
5369 Also, one must remember that if packet is duplicated then its
5370 reference count must be decresed by calling the free function as
5371 many times as it was duplicated.
5373 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5374 from both client and server.
5376 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Made joining to a channel working in router environment.
5380 * Cleaned up JOIN command on server side and create function
5381 silc_server_command_join_channel internal routine to make the
5384 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Changed silc_command_pending list to SilcDList. Also, added
5387 `ident' field to SilcServerCommandPending structure to identify
5388 the reply and to call correct callback.
5390 Added silc_server_command_pending_check function to replace the
5391 corresnponding macro. The silc_command_pending list is not
5394 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5395 to set identifier to previously allocated Command Payload. It
5396 is used to set identifier for command when resending Command
5399 * Added silc_command_payload_encode_payload to encode Command
5400 Payload buffer from SilcCommandPayload structure.
5402 * Added silc_argument_payload_encode_payload to encode Argument
5403 payload buffer from SilcArgumentPayload structure.
5405 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Changed WHOIS command to support router connection on server side.
5408 The whois request is always sent to router unless the server is
5409 standalone server. After server has received the reply from the
5410 router will it send the reply to the client.
5412 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5413 broadcast received broadcast packet. The function is used only
5414 by router. The broadcast packet is always sent to the router's
5417 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5418 render given ID to printable string, for log files for example.
5420 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Made basic router to router connections working. At least they
5423 can now connect to each other but nothing really works the way
5424 they are supposed - yet.
5426 * Added new initiator token to RouterConnection configuration
5427 file in silcd/serverconfig.[ch]. It is used to tell whether we
5428 are the initiator to the remote router or whether we'll expect
5429 the other end to connect.
5431 * Moved registering of listener task to silc_server_init, hence
5432 the server starts listenning as soon as it is run, even if it
5433 does not have connections to other routers. Let's see how well
5436 * Changed default connection retry timeouts for more suitable in
5439 * Removed cipher and such arguments from silc_idlist_add_client
5440 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5441 Added new function silc_idlist_add_data to add the keys and stuff
5444 * Added SilcIDListData structure and added it to SilcClientEntry
5445 and SilcServerEntry as their first field in the structure. This
5446 way we can explicitly cast the ID entries to the SilcIDListData
5447 structure and get common data for the entries. In past, we had
5448 to first check what type of connection it is and then cast it to
5449 correct ID entry type. Now, we can directly cast the opaque
5450 pointer to the SilcIDListData (no matter what ID entry it actually
5451 is) and get the data needed.
5453 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5456 in some circumstances even if threre were timeout tasks, though not
5457 IO tasks, but tasks anyway. Now fixed.
5459 * Defined SilcServerConnection structure to hold connection specific
5460 stuff about directly connected servers and routers. The definition
5461 is currently in silcd/server_internal.h. I thought about having
5462 a bit more important role fro this struct but for now it is used
5463 only when connecting to other server (or router actually).
5465 * Added connecting retry support in server when connecting to
5466 router(s). The retry feature implement exponential backoff
5467 algorithm. Also, added SilcServerParams structure to hold default
5468 parameters for server. For now, it include these retry settings
5469 and are hard coded. After server is moded to be as Silc Server
5470 Library this structure will be more important.
5472 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Changed client librarys channel->clients table to SilcList and
5475 changed code accordingly.
5477 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Changed client's channel table to SilcList and changed code
5480 accordingly. Also changed SilcChannelClientEntry to include back-
5481 pointer to the channel so that client entry can use that structure
5482 as list as well and we have fast cross-reference to the channel.
5483 This change dramatically decreased the complexity of channel
5484 handling with client entry and vice versa (removed one extra
5485 loop when searching for channel entry from many functions).
5487 * Changed server->sim from table to SilcDList and changed code
5490 * NAMES command can now be used from user interface. It will show
5491 the user list on the channel, neatly.
5493 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5494 Code now saves realname of the user if it becomes available.
5496 * Renamed configure.in to configure.in.pre and made ./prepare
5497 script to automatically add correct version string to
5498 configure.in which it creates from configure.in.pre.
5500 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * NAMES command reply now shows users mode with the nickname when
5505 * Moved silc_client_ch[u]mode[_char] functions from
5506 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5507 place sucks, they are utility functions and should be in some
5510 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5512 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5515 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added TRQ (efficient deque and list library) into lib/trq. This is
5520 a very good list library that is currently used in the SILC. Defined
5521 SilcList API over the library because I didn't like the API very
5522 much. See lib/trq/silclist.h for the API and examples of how to
5523 use the API. Fixed various places in the code to use the new
5524 SilcList API. The SilcList is meant for lists that has a structure
5525 already defined as a list. It is not suitable to add just some
5526 context to the list (in TRQ, the context is the list actually).
5528 So, I defined SilcDList that can be used for the purpose where
5529 predefined list structure does not exit. This can be used as
5530 such list. Now some context just can be added to the SilcDList.
5531 Currently this list is not used in the SILC just yet, though there
5532 are a lot places where this can replace dynamically allocated
5533 tables and I will fix these places, later, to use SilcDList.
5534 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5535 and use TRQ internally).
5537 Also fixed some annoying warning messages that the original TRQ
5538 code generated. Also minor changes to TRQ's Makefile.in.
5540 * Added support for querying by Client ID to both WHOIS and
5541 IDENTIFY commands into server, as required by the protocol.
5543 * Removed method function pointers from SilcBuffer structure. They
5544 weren't used to anything and just increased the context size for
5545 no good reason. This change also made silc_buffer_alloc and
5546 silc_buffer_free functions inline functions.
5548 * Disabled command flooding detection support until it's fixed so
5549 that it accepts commands in but does not execute them more than once
5552 * Added silc_net_localhost(), to return local hostname, into
5553 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5554 that must be initialized before calling silc_client_init.
5556 * Added new function: silc_server_send_notify_on_channels to send
5557 notify messages to all channels client has joined. It is assured
5558 that the message is sent only once per client.
5560 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5561 lib/silcutil/silcutil.[ch] as silc_format function. The new
5562 function is generic and is used by server as well, not only by
5563 the logging routines.
5565 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5566 the provided version string was not acceptable. Added new function:
5567 silc_ske_check_version into lib/silcske/silcske.h. The function
5568 must be implemented by the application (client or server) and it
5569 does not reside in the SKE library. The function checks the version
5570 string remote end sent.
5572 * Added back pointers (to opaque context and to SilcSocketConnection)
5573 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5575 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5576 duplicate packet context structure.
5578 * Changed `notify' client operation to send same arguments as client
5579 receives from server except for ID's. ID's are mapped to correct
5580 ID entry and that is returned. Also, if channel entry is not sent
5581 by server but the notify is for channel the channel entry is sent
5582 to application (otherwise application doesn't know that it is for
5583 channel (library gets it from packet's Destination ID)).
5585 * Added silc_client_remove_from_channels into client library to
5586 remove a client from all channels it has joined to. Used when
5587 received SIGNOFF notify from server. Added also new function
5588 silc_client_replace_from_channels to replace old ID entry with
5589 new ID entry on all channels. Used when received NICK_CHANGE
5592 * Fixed ID Cache list handling in silc_idlist_get_client in
5593 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5594 to get (or query) client by ID.
5596 * Updated TODO list.
5598 * Added connection authentication status message defined by the
5599 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5600 support for these into the code in client and server side.
5602 * Added generic function silc_client_send_command to send any command
5603 with variable argument list. Application should use this function
5604 to send commands if the command functions provided by the library
5605 does not suite for the application's user interface needs.
5607 * Added new `failure' client operation. Application is notified about
5608 received failure packet if client is executing a protocol. In this
5609 case the protocol's execution has failed.
5611 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5612 is required by the protocol.
5614 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5615 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5618 * Added status flag to SilcSKE object to indicate realtime status
5619 of the SKE protocol.
5621 * Application receives now exactly same command reply arguments as
5622 the library receives from server. However, if ID is received the
5623 corresponding ID entry is returned to the application (eg. Client
5624 ID is mapped to correct SilcClientEntry entry and that is returned).
5625 Changed command_reply client operation due to this change.
5627 * Changed all ID's in commands and in command replys as ID Payloads.
5628 Change affected both client and server side codes.
5630 All ID's sent in SILC network (with execption of ID's in SILC
5631 Packet header) are sent in ID Payload to support variable length
5634 * Server now notifies nick changes and notifies all clients on
5635 the channels about the new nickname (about the new Client ID,
5638 * Implemented CMODE command to change channel modes. Supports all
5639 channel modes defined by the protocol specs except ban and invite
5640 lists. (Also, private channel key mode is supported but support for
5641 setting private channel key in client is missing, thus, this mode
5642 has no effect on client side (except that server requires that the
5643 client uses private channel key and normal channel traffic does not
5646 Also, invite mode works per se, but INVITE command does not work
5647 yet correctly, so you can set channel as invite only channel but
5648 inviting clients to the channel does not work (it is yet to be
5649 thought what's the best way to do it).
5651 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5652 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5653 Implemented CUMODE command to change user's mode on the channel.
5654 Supports all modes defined by the protocol specs.
5656 * Added NAMES command reply to return users modes on the channel.
5658 * Removed unnecessary and slow ciphers from lib/silccrypt.
5660 * Set SO_KEEPALIVE option to connection sockets by default.
5662 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5664 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5665 redefined the Notify Payload into protocol specs.
5667 * Added silc_id_payload_parse_id to get ID directly from raw
5670 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5673 accept searching by Client ID as well.
5675 * Added support for LEAVE and SIGNOFF notify types in client library.
5677 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5678 to parse ID Payload from raw data.
5680 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Added flags parameter into silc_ske_assemble_security_properties
5683 function in lib/silcske/silcske.[ch].
5685 * Changed notify client operation to fit better for notify messages
5686 sent by server. The notify payload received from server is now
5687 passed to the application (after parsing it to SilcNotifyPayload).
5688 It is application's responsibility to retrieve the arguments
5689 from the payload and show the message the way it wants. The message
5690 sent by server is implementation specific.
5692 * Changed public keys to comply with the protocol specification.
5693 Old public keys are not supported anymore and are not compatible.
5695 * Removed nickname from Channel Payload as the latest draft removed
5696 it. The client must resolve the nickname from the NAMES command
5697 reply received when it joined the channel.
5699 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5701 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Fixed some errors in protocol specification drafts.
5705 * Created lib/silccore/silcnotify.c to implement Notify Payload
5706 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5707 generic payloads described by protocol specifications. The file
5708 includes implementations for ID Payload and Argument Payload.
5710 * Changed Command Payload implementation to use the new Argument
5711 Payload. Changed command_xxxx_payload to command_payload_xxxx
5712 to comply with SILC coding conventions.
5714 * Added suppport for Argument Payload handling in Notify Payload
5715 implementation as protocol requires it. Added the new support
5716 into server and client lib as well.
5718 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Added support for multiple nicknames on same channel. [n] is
5721 added locally to the nickname if there are more than one same
5722 nicknames on the channel.
5724 * Server now sends all nicknames that matched WHOIS request.
5725 Client also shows the list received from server.
5727 * Added TOPIC command to client side. User can now set and show
5728 current topic on channel.
5730 * Added MOTD command to client and server. Also, server sends the
5731 motd when client connects to the server.
5733 * Changed version strings to comply ISO 8601.
5735 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Fixed protocol error handling in client library. It should now
5738 cope even if the SKE fails for some reason.
5740 * Made new protocol specification drafts for submitting to IETF.
5742 * Implemented TOPIC command to server in silcd/command.c.
5744 * Added two new notify types into lib/silccore/silcnotify.h:
5745 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5746 notify nickname change and topic setting/change on a channel.
5748 * API change of command_reply operation in client library. The
5749 application gets now the status type received from server as well.
5751 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5755 * Cras fixed and optimized the packet handling even further and
5756 it should work now. Minor change to the prototype of function
5757 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5759 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added new function into lib/silcutil/silcschedule.[ch]:
5762 silc_schedule_with_fd to select() a specified fd. The function
5763 returns after timeout expires or data arrives or goes. The
5764 function is used by packet routines to wait that all data is
5765 received from network.
5767 * Fixed data reading from network in lib/silccore/silcpacket.c.
5768 The code now assures that all data is read from the fd and then
5769 continues packet processing. This was a bug fix since the code
5770 used to drop some data in some circumstances.
5772 * Added new function into lib/silcclient/client.[ch]:
5773 silc_client_start_key_exchange to start key exchange after
5774 connection has been established to server. The code internally
5775 now uses this funtion but its main purpose was to provide it
5776 for applications that perform their own connecting. After
5777 application has created a connection it merely calls this
5778 function to start the key exchange between client and server.
5779 The library takes care of everything else after that.
5781 Updated also lib/silcclient/README to explain the usage of
5784 * Do not send to application information that connection has
5785 been established. Application gets notified it by connect
5788 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Applied cras's patch to add silc_schedule_one function. The
5791 function runs scheduler once and returns.
5793 * Fixed the scheduler after cras messed it up. The timeout
5794 handling works now as it's supposed to work.
5796 * Added into lib/silccore/ silcnotify.h to include notify
5797 message types support. Changed silc_server_send_notify*
5798 functions, in server.[ch], to support those new notify types.
5799 Added the support for the notify types into client library,
5800 as well. Added new notify client operation into ops.h in
5803 * Changed silc_server_packet_send_to_channel to send normal
5804 packets instead of just channel message packets. The function
5805 is now used to send the notify packets to channels. It is not
5806 used to send channel message packets anymore, as server never
5809 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5810 va_arg()s as it seems to require it nowadays. I guess, if SILC
5811 is compiled with older va_arg() the new code should work anyway.
5813 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Splitted core library. Core library (lib/silccore) includes
5816 now only SILC protocol specific core (and common) components.
5817 Created new utility library (lib/silcutil) that includes more
5818 generic purpose stuff. The stuff for util library was taken
5819 from the old core library. This was minor and easy split.
5821 * Created SILC Client Library (lib/silcclient) that includes
5822 implementation of the SILC client without user interface. This
5823 was major move from silc/ directory. The code has been changed
5824 so that it is transparent towards the user interface. The
5825 silc/ directory includes now the same user interface as before
5826 and it uses the new client library. Read lib/silcclient/README.
5827 Basicly, the client library performs everything else related
5828 to SILC except user interface handling. Also, configuration
5829 files are considered to be part of user interface and library
5830 does not handle them.
5832 This change also changed a lot of structures, function naming etc.
5833 Most important change was that SilcClientWindow object was
5834 renamed to SilcClientConnection in the client library. Created
5835 also new file lib/silcclient/ops.h. Also added new files
5836 silc/local_command.[ch] and silc/client_ops.[ch].
5838 All these changes were made to make it easier for user interface
5839 designers to create what ever user interface for the SILC client
5842 It is also expected that the server will be moved to lib
5843 directory as well and SILC Server Library will be created;
5844 sometimes in the future.
5846 * Removed Local commands from lib/silccore/silccommand.h as
5847 they are application specific and new client library does not
5848 handle any of those anymore.
5850 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5851 old client implementation in silc/.
5853 * Added support for callback functions in SILC_LOG_* macros.
5854 Application can now set its own callbacks that will be called
5855 instead of using the default functions that will always print
5856 the debug messages to stderr (or stdout). Also, debugging can
5857 now be disabled by setting silc_debug to FALSE and re-enabled by
5858 setting it to TRUE. Note, that logging will still work even
5859 if debugging is disabled.
5861 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5862 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5863 silc_log_reset_debug_callbacks.
5865 * To enable debugging in silc client one must give now -d
5866 option on command line.
5868 * Changed silc_schedule_init to automatically allocate task queues
5869 if they are not allocated before calling it.
5871 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Added GMP 3.1 into math library.
5875 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5878 a channel in SILC network. The packet is used by servers and
5879 routers to notify other routers that user has left a channel.
5880 This little feature was missing until now. Added the feature
5881 to protocol specification as well.
5883 Added functions: silc_server_send_remove_channel_user and
5884 silc_server_remove_channel_user into server.[ch].
5886 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5887 lib/silccore/silcpacket.h. However, they are not implemented
5890 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Fixed joining to a channel and sending channel messages
5893 between server and router. The channel message sending should
5894 now work inside a cell.
5896 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Fixed the private message sending between server and router.
5899 The private message sending should now work inside a cell.
5901 * Added silc_server_replace_id into server.[ch] to replace
5902 existing ID in the SILC network.
5904 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5905 and silc_idlist_replace_server_id into idlist.[ch] in server.
5907 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Fixed the server to server connections. Server can again now
5910 connect to router. Router to router connections probably does
5913 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added dynamic protocol registering support. Now protocols can
5916 registered and unregistered on the fly. Patch by cras.
5918 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Added lib/contrib directory to hold routines that some platforms
5921 don't have but are needed by SILC.
5923 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5924 into lin/contrib to provide getopt() and getopt_long() for
5925 those who don't have it.
5927 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added AWAY command to client. When away message is set and
5930 client receives a private message packet the client automatically
5931 replies to the sender with the away message.
5933 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5934 bug seemed to be the cause of recent problems when compiling
5937 * Added version detection support to SKE protocol specification
5938 and added the new changes to the SKE implementation as well.
5939 There were other minor changes in the SKE protocol as well.
5941 Many changes in lib/silcske/silcske.[ch] and in
5942 lib/silcske/payload.[ch].
5944 * Added ^U functionality, clear input line. Patch from cras.
5946 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Mainly small bugfixes on core library. Fixed some debugging
5949 logging and buffer overflow in silclog.c.
5951 * Updated config.sub and config.guess on the distribution tree.
5953 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Added command lagging support in server. Client may execute
5956 commands now only once in two seconds.
5958 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Optimized packet reception. MAC computation and checking is now
5961 also more optimized. A lot previously duplicated code is now
5962 used as generic by both client and server.
5964 * Fixed key pair generation in clientutil.c
5966 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Added into lib/silccore/silcbufutil.[ch] new function;
5969 silc_buffer_realloc.
5971 * Moved generic packet sending/encryption functions to
5972 lib/silccore/silcpacket.[ch] from client and server. Some
5973 rewriting of the functions.
5975 * Moved all generic packet reception/decryption functions to
5976 lib/silccore/silcpacket.[ch] from client and server. The
5977 packet processing is now much cleaner in both client and server.
5978 These were major changes in both client and server.
5980 * Created many common functions in server to do packet sending.
5981 Previously code were duplicated a lot, this has been removed
5984 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Rewrote major parts of the ID cache system. Don't know
5987 whether it is better now or not but at least the API is more
5990 * Major rewrite on ID cache stuff on client because of the ID
5991 cache API changes. Added idlist.c to client.
5993 * Also major rewrite on ID cache stuff on server as well.
5994 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5995 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5996 in hand, instead they are all put into the ID cache system now.
5997 All server_idlist_* routines uses ID cache now instead of
5998 traversing its own lists (those lists does not exist anymore).
5999 SilcIDList though still exists. Also, SilcXXXEntry's are
6002 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Finally made the SKE implementation compliant to the protocol
6005 specification. All mp integers are now binary encoded as
6006 opposed being HEX encoded.
6008 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6011 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6012 functions: silc_[encode/decode]_pem. Also added function
6013 silc_encode_pem_file to PEM encode with newlines ('\n') for
6016 * SILC public keys are now encoded either PEM or binary. Same
6017 option is for private keys as well. By default private keys
6018 are binary encoded and public keys PEM encoded. Silly HEX
6019 encoding were removed.
6021 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6022 function to create fingerprints.
6024 * Fixed a bug in SHA1; does not change the original data anymore.
6026 * Partly implemented INFO command on client and server side.
6027 Fixed CLEAR command. Changes to SERVER command; show current
6028 server(s) when giving command without arguments. Added
6029 VERSION command to client.
6031 * Added check to server that unregistered connections cannot
6032 execute commands (unless it is specificly allowed).
6034 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Fixed screen refresh.
6038 * Fixed channel joining bug from client. On some circumstances
6039 client tried to join to a channel it had already joined.
6041 * Added public key verification process into client's protocol.c.
6042 The client now verifies the public key from user and saves
6043 it into ~./silc/serverkeys/ directory.
6045 Added into: clientutil.[ch]: silc_client_verify_server_key.
6047 * Changed SKE protocol's silc_ske_initiator_finish function
6048 to accept callback function that verifies the received public
6049 key. Removed old silc_ske_verify_public_key function.
6051 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6054 silc_pkcs_private_key[_data]_set.
6056 * Made the password and public authentication more cleaner in
6057 server's protocol.c.
6059 * Removed historic and obsolete protocol `channel_auth' from
6060 both client and server.
6062 * Removed wrong way of sending command status messages from
6063 server to client in server's command.c. The old way violated
6064 protocol specification.
6066 Changes to silccore/silccommand.[ch]: removed
6067 silc_command_encode_status_payload -> not needed anymore,
6068 changed silc_command_encode_payload_va to accept extra
6069 argument on variable argument list. The argument type must
6070 now be provided to the function. Also, added new function:
6071 silc_command_encode_reply_payload_va which is same as
6072 normal command_encode_payload_va except command status type
6073 is provided as extra argument.
6075 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Added ~./silc directory handling. The directory includes the
6078 public and private keys for the client.
6080 Added silc_client_check_silc_dir, silc_client_create_identifier
6081 and silc_client_load_keys.
6083 * Implemented SILC protocol compliant public key. Added public
6084 and private key saving to and loading from files.
6086 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6087 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6088 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6089 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6090 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6092 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6093 silc_pkcs_load_[public/private]_key.
6095 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Added silc_server_get_route (route.[ch]) to get connection
6098 data for the fastest route for given ID.
6100 * Implemented INVITE command on client and server. The command
6101 were re-defined in the SILC Protocol Specification and the
6102 implementation now complies with the specification.
6104 * Implemented PING command on client and server.
6106 * Implemented NAMES command on client and server. The server side
6107 supports currently only normal server not router server yet.
6108 Some changes to NAMES definition in SILC protocol specification.
6110 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Implemented LEAVE command on client and server.
6114 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6115 again. This change was made to the protocol as well. Server
6116 should not violate the protocol specification anymore.
6118 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6121 was tested. SOCKS4 was not but should work anyway.
