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

265 in JOIN command. Affected file lib/silcclient/command.c.
267 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Assure that silc_server_close_connection cannot be called
270 twice for same socket context. Affected file is
273 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
275 * Send error message to application if opening file for
276 writing during file transfer fails. Affected file is
277 lib/silcclient/client_ftp.c.
279 Remove all file transfer sessions for a client that we're
280 removing from ID cache.
282 Affected file is lib/silcclient/client_ftp.c.
284 * Fixed silc_net_addr2bin to return correct address. Affected
285 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
287 * Fixed file transfer session removing on signoff notify.
288 Affected file irssi/src/silc/core/silc-servers.c.
290 * Added the SilcClientFileError to be returned in the monitor
291 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
292 Affected file lib/silcclient/silcapi.h.
294 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
296 * Fixed a crash in silc_client_ftp_free_sessions and
297 silc_client_ftp_session_free_client. Affected file
298 lib/silcclient/client_ftp.c.

301 to indicate if the server entry is disabled. Affected file
302 silcd/idlist.h, silcd/command[_reply].c.
304 * SILC server adds now /var/run/silcd.pid everytime it is
305 started. Affected file silcd/silcd.c.
307 * Added silc_server_packet_send_clients to send a packet to
308 the provided table of client entries. Affected file
309 silcd/packet_send.[ch].
311 * Fixed a crash in client resolving in client_prvmsg.c in
312 client library. Affected file lib/silcclient/client_prvmsg.c.
314 * Do not actually remove the client directly from ID cache
315 during SERVER_SIGNOFF, but invalidate it. This way we
316 preserve the WHOWAS info for the client. Affected file
319 * Fixed SERVER_SIGNOFF notify handling in the server. The
320 server is now able to process incoming SERVER_SIGNOFF notify
321 for a server that it doesn't even know about. It will remove
322 the clients provided in the notify. Affected file
323 silcd/packet_receive.c.
325 * Check for partial packet in data queue after every packet that
326 was found from the queue. Return and wait for more data if
327 there is partial data in queue. Affected file is
328 lib/silccore/silcpacket.c.
330 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
332 * Added SilcClietFileError enum to indicate error in
333 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
334 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
335 Affected files lib/silcclient/silcapi.h and
336 lib/silcclient/client_ftp.c.
338 * Check that newsize in silc_buffer_realloc is larger than
339 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
341 * Added better monitor of file transfers. It now monitors
342 key agreement protocol during the file transfer too. Added
343 error reporting too. Affected files
344 irssi/src/silc/core/silc-servers.c,
345 irssi/src/fe-common/silc/module-formats.[ch].
347 * Wrote a help file for FILE command.
349 * Added silc_rng_global_get_byte_fast to get not-so-secure
350 random data as fast as possible. Random data is read from
351 /dev/urandom if available and from the SILC RNG if not
352 available. It is used in padding generation. Affected file
353 lib/silccrypt/silcrng.[ch].
355 * All packets in client library are now processed synchronously.
356 Optimized packet processing a lot. Affected file
357 lib/silcclient/client.c.
359 * All server connection packets are processing synchronously
360 now in server, to optimize packet processing. Affected file
363 * Include files are installed now only in Toolkit distribution
364 if make install is given. Affected files: all Makefile.am's.
366 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
368 * Assure that silc_client_notify_by_server_resolve does not
369 resolve the client information multiple times. If it cannot
370 be found by the first it cannot be found at all. Affected
371 file lib/silcclient/client_notify.c.
373 * Fixed WHOWAS command reply calling. Affected file
374 lib/silcclient/command_reply.c.
376 * Removed all references to silc_idlist_get_client from the
377 Irssi SILC client since that call is internal call used by
378 the library. The Irssi SILC client will use now client
379 retrieval functions found in silcapi.h.
381 * Fixed a bug in resolving nickname info before sending
382 private message. It used freed memory. Affected file
383 irssi/src/silc/core/silc-servers.c.
385 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
387 * Assure my_channels statistics cannot go negative in server.
388 Affected files silcd/server.c, silcd/server_util.c.
390 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

400 lib/sftp/sftp_fs_memory.c.
402 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
404 * Added silc_net_localip to return local host's IP address.
405 Affected file lib/silcutil/silcnet.[ch].
407 * If key exchange or rekey protocol is active for a connection
408 parse all packets syncronously since there might be packets
409 in packet queue that we are not able to process without first
410 processing packets before them. Affected file silcd/server,
411 lib/silcclient/client.c.
413 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
414 whether library should continue processing the packet.
415 Affected file lib/silccore/silcpacket.h.
417 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
418 SilcSFTPMonitorData to SFTP server to monitor various
419 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
420 lib/silcsftp/sftp_server.c.

423 lib/silcutil/silcutil.[ch].
425 * Implemented the file transfer support for the client library.
426 Added preliminary support for simple client to client one-file
427 transmission. Affected file lib/silcclient/client_ftp.c,
428 lib/silccilent/client.[ch].
430 * Added new local command FILE to the Irssi SILC Client.
431 It is used to perform the file transfer. It has subcommands
432 SEND, RECEIVE, SHOW and CLOSE. Affected files
433 irssi/src/silc/core/client_ops.c,
434 irssi/src/silc/core/silc-server.[ch].
436 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
438 * Relay the SILC_PACKET_FTP in the server. Affected files
439 silcd/server.c and silcd/packet_receive.c.
441 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Renamed silc_file_read and silc_file_write to functions
444 silc_file_readfile and silc_file_writefile. Added function
445 silc_file_open and silc_file_close. Affected files
446 lib/silcutil/silcutil.[ch].
448 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
450 * Resolve the client info when received private message or
451 channel message for a client which nickname we don't know.
452 Affected files lib/silcclient/client_prvmsg.c and
453 lib/silcclient/client_channel.c.
455 * Do not crash in /KEY if client is not connected. Affected
456 file irssi/src/silc/core/silc-channels.c.
458 * Added SilcClientStatus field to the SilcClientEntry in the
459 lib/silcclient/idlist.h.
461 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
462 is incomplete and is being resolved, it won't be resolved
465 Make sure also that USERS command reply does not resolve
466 twice information. Affected file is
467 lib/silcclient/command_reply.c.
469 Make sure that silc_client_get_clients_by_list does not
470 resolve twice same information.
472 * Check for valid client->id in the silc_server_free_client_data.
473 Affected file silcd/server.c.
475 * Fixed /GETKEY nick@server not to crash if the server entry
476 is not found. Affected file lib/silcclient/command.c.
478 * Fixed the silc_server_check_cmode_rights to check the
479 requested modes correctly. Affected file silcd/command.c.
481 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Better checks for non-printable chars in nick added.
484 Affected file silcd/command.c.
486 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Call the silc_server_udpate_servers_by_server in the
489 primary router that comes back online in the backup resuming
490 protocol. Otherwise it routes packets wrong. Affected file
491 silcd/server_util.[ch], silcd/server_backup.c.
493 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
496 lib/silcutil/silcbuffmt.[ch].
498 * Redefined the SILC packet header to include the padding
499 length. Affected file lib/silccore/silcpacket.[ch].
501 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
502 length for maximum padding up to 128 bytes). Affected
503 file lib/silccore/silcpacket.h.
505 * Removed all backwards support for old 0.5.x MAC thingies.
506 The SILC packet header change makes it impossible to be
507 backwards compatible.
509 * Send the ENDING packet with timeout in the backup resuming
510 protocol. This is to assure that all routers has connected
511 to the primary router. Affected file silcd/server_backup.c.
513 * Changed the RNG to take the first IV from random data. It
514 used to take it from zero actually. Changed the RNG also
515 to use /dev/urandom during session. /dev/random is used
516 in initialization. Affected file lib/silccrypt/silcrng.[ch].
518 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
520 * Changed the SILC packet header to have the first two bytes
521 (the packet length) encrypted. Affected files aroung the
522 code tree, lib/silccore/silcpacket.[ch]. Removed the
523 SilcPacketCheckDecrypt callback. It is not needed anymore
524 since the silc_packet_receive_process will determine now
525 whether the packet is normal or special.
527 * Implemented the unidirectional MAC keys. Affected files
528 lib/silcske/silcske.c, silcd/protocol.c and
529 lib/silcclient/protocol.c.
531 * Implemented the packet sequence number to the MAC computation.
532 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
533 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
534 lib/silcclient/protocol.c.
536 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
538 * Allow backup router to announce servers. All servers
539 announced by backup router are added to the global list
540 automatically. Update hte server's socket to our primary
541 router also when backup router announces a server.
542 Affected file silcd/packet_receive.c.
544 * Do not update the client->router in the function
545 silc_server_udpate_clients_by_server if the client is on
546 global list. We might fail to find any specific server
547 for locally connected clients and local cell clients. They
548 should still use the `from' and not `to' as client->router.
549 This fixes backup router resuming protocol. Affected file
552 * Decrease channel statistics count only if the channel
553 deletion worked. Affected files are silcd/server.c and
556 * Added silc_server_update_servers_by_server to update origin
557 of all server entries. Used during backup router protocol.
558 Affected files silcd/server_util.[ch], silcd/server.c. and
559 silcd/backup_router.c.
561 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
562 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
563 silc_hmac_get_hash and silc_hmac_get_name. Affected file
564 lib/silccrypt/silchmac.c.
566 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Assure that router cannot reroute the same channel message
569 to the sender. Affected file silcd/packet_receive.c.
571 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
573 * Made better checks that the channel message is not sent
574 to the router it came from. Affected file is
575 silcd/packet_send.c. Fixed memory leak too.
577 * Announce informations for incoming router connection, but
578 only after checking if it is replaced by backup router.
579 Affected file silcd/packet_receive.c.
581 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
583 * Fixed the backup resuming protocol to work in multiple
584 router environment. Affected file silcd/server_backup.c.
586 * Route packet only to one router in the function
587 silc_server_packet_send_to_channel. Affected file is
590 * Fixed silc_server_send_notify_dest to set the broadcast
591 flag. Fixed the silc_server_send_notify_topic to actually
592 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
593 Affected file silcd/packet_send.c.
595 * Changed the SFTP Filesystem interface. Changed the
596 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
597 the filesystem operation function. The SilcSFTPFilesystem
598 is now a context that is allocated by all filesystem allocation
599 functions and it already includes the operations structure
600 and filesystem specific context. It is given as argument
601 now to the silc_sftp_server_start. This made the interface
602 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
603 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
605 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
607 * Changed the backup router adding and getting interfaces
608 in the server. The router that will be replaced by the
609 specified backup router is now sent as argument. Affected
610 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
613 * Added silc_net_addr2bin_ne to return the binary form of
614 the IP address in network byte order. Affected files
615 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
617 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Check for existing server ID in silc_server_new_server
620 and in silc_server_connect_to_router_final and remove the
621 old entry if it exists. Affected file silcd/packet_receive.c,
624 * Send the channel message always to only one router, either
625 in upstream or downstream. Affected file is
628 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
630 * Wrote the definition of the backup resuming protocol to the
631 protocol specification.
633 * Removed one redundant channel key generation from normal
634 server during joining procedure. Removed one redundant
635 channel key sending from server to router during joining
636 procedure. Affected file silcd/command.c.
638 * Made minor bugfixes to the backup router resuming protocol.
639 Affected file silcd/server_backup.c, server.c.
641 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Added --disable-asm configuration option. Affected files
644 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
647 * Implemented the backup resuming protocol that is used to
648 resume the primary router position in the cell after the
649 primary router comes back online. Affected files
650 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
651 and silcd/server_util.[ch].
653 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
655 * Sleep two (2) seconds after sending QUIT command to server.
656 Affected file lib/silcclient/command.c.
658 * Assure that if outgoing data buffer is pending do not force
659 send any data. Affected file silcd/packet_send.c.
661 * Assure that if outgoing data buffer is pending do not force
662 send any data. Affected file lib/silcclient/client.c.
664 * Implemented the backup router support when the primary router
665 goes down. The servers and routers can now use the backup
666 router as new primary router without loosing connectivity.
668 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
670 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
671 in the server to indicate disabled entry. All data read
672 from the connection will be ignored and no data is sent
673 for entry that is disabled. Affected files are
674 silcd/idlist.h, silcd/server.c.
676 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
678 * Created SFTP client and server test programs in the
679 lib/silcsftp/tests directory.
681 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
683 * Implemented memory filesystem (virtual filesystem) for
684 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
687 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Implemented the SFTP (SSH File Transfer Protocol) to the
690 lib/silcsftp. It includes SFTP client and SFTP server
693 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Moved lib/silccore/silcprotocol.[ch] to the
696 lib/silcutil library.
698 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
699 take variable argument list pointer as argument. Affected
700 file lib/silcutil/silcbuffmt.[ch].
702 * Added silc_buffer_set function that is used to set data
703 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
704 Affected file lib/silcutil/silcbuffer.h.
706 * Changed various routines in the core library to use the new
707 silc_buffer_set instead of allocating new buffer only for
710 * Added 64-bit value formatting and unformatting support to the
711 silc_buffer_[un]format routines. Affected file is
712 lib/silcutil/silcbuffmt.[ch].
714 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
715 to includes/bitmove.h.
717 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
719 * Fixed channel user mode saving in client library. Affected
720 file lib/silcclient/command[_reply].c.
722 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
724 * Defined the file transfer to the SILC Protocol. Added
725 new packet type SILC_PACKET_FTP and defined File Transfer
726 Payload. The mandatory file transfer protocol is SFTP
727 (SSH File Transfer Protocol). Affected file in addition
728 of the internet draft is lib/silccore/silcpacket.h.
730 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
731 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
732 is used as part of backup router protocol when the primary
733 router of the cell is back online and wishes to resume
734 the position as primary router.
736 * Redefined the MAC generation keys in the protocol. The
737 same key is not used anymore in both direction. Both
738 direction will now use different keys for sending and
739 receiving. This fixes a potential security flaw. This
740 change causes incompatibilities in the protocol.
742 * Redefined also the MAC computation from the packet.
743 An packet sequence number is now added to the MAC
744 computation. This prevents possible replay attacks against
745 the protocol. This change too causes incompatibilities
748 Added `sequence' field to the SilcPacketContext to hold
749 the current sequence number for the packet.
751 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
753 * Added `created' field to the SilcIDListData in the file
754 silcd/idlist.h to indicate the time when the entry was
757 * Added `created' field to the SilcChannelEntry too. Affected
760 * Added `creation_time' aguments to all the announcement functions
761 in the server. If it is provided then only the entries that
762 was created after the provided time frame are actually
763 announced. Affected file silcd/server.[ch].
765 * The protocol says that the Channel ID's IP address must be
766 based on the router's IP address. Added check for this in
767 the silc_server_new_channel when processing incoming New Channel
768 Payload. Affected file silcd/packet_receive.c.
770 * Print out the correct version with --version in SILC client.
771 Affected file irssi/src/silc/core/silc-core.c.
773 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Fixed WHOWAS command to check for completnes of the client
776 entry always, not just when the command is coming from client.
777 Affected file silcd/command.c.
779 * Added new function silc_server_packet_queue_purge to purge the
780 outgoing data queue to the network. After the function returns
781 it is guaranteed that the outgoing packet queue is empty.
782 Affected file silcd/packet_send.[ch].
784 * Purge the outgoing packet queue in the rekey protocol's final
785 callback to assure that all rekey packets go to the network
786 before quitting the protocol. Affected file silcd/server.c.
788 * Added silc_client_packet_queue_parse as similar function as
789 in server to the client library. The affected file is
790 lib/silcclient/client.c.
792 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Splitted silcd/server.c and created silcd/server_util.[ch]
795 for utility functions.
797 * Added new socket flag SILC_SF_DISABLED to indicate that the
798 connection is open but nothing can be sent to or received from
799 the connection. Affected file lib/silcutil/silsockconn.[ch].
800 The checking for disabled socket is checked in the low level
801 silc_socket_write and silc_socket_read functions.
803 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Allow only nicknames and channel names that fits into the
806 7-bit unsigned char ASCII set. Affected file silcd/command.c.
808 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
810 * When processing JOIN command reply in server check that if
811 the channel exists in our global list we'll move it the local
812 list. Affected file silcd/command_reply.c.
814 * Fixed the check whether client is joined on the channel already
815 in JOIN command. Affected file lib/silcclient/command.c.
817 * Fixed the JOIN command reply to check whether the channel
818 already exists. Affected file lib/silcclient/command_reply.c.
820 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
822 * Added silc_ske_status_string to map the SKE error numbers
823 to readable strings. The affected files are
824 lib/silcske/silcske[_status].[ch].
826 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Do not show the private channels on the WHOIS channel list
829 as it is not allowed by the protocol. The affected file is
832 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Assure that the packet length digged from the actual packet
835 is something sensible in the silc_packet_decrypt_rest_special
836 in lib/silccrypt/silcpacket.c.
838 * Free and NULL the allocated pointer in silc_hmac_alloc if
839 the HMAC allocation fails. The affected file is
840 lib/silccrypt/silchmac.c.
842 * Print the selected security properties to the log files in
843 the server. Affected file silcd/protocol.c.
845 * Add SKE's reference counter even if calling the completion
846 callback manually. Otherwise it goes negative, although it
847 does not cause any problems. The affected file is
848 lib/silcske/silcske.c.
850 * Remove the client entry with short timeout after giving the
851 KILL command. Affected file lib/silcclient/command.c.
853 * Fixed to send error reply in WHOIS and IDENTIFY commands in
854 case all found clients are already disconnected (WHOWAS would
855 found them) in the server. Affected file silcd/command.c.
857 * Update the last_receive (time of last data received) to be
858 updated only when received private or channel message so that
859 the idle time showed in WHOIS makes more sense.
861 * Added boolean field `valid' in to the SilcClientEntry in the
862 client library to indicate whether the entry is valid or not.
863 This fixes the nickname change bug on channel when changing
864 the nickname to be same than the old (like nick to Nick) the
865 nickname formatter doesn't set the new nick anymore to Nick@host.
866 Affected file lib/silcclient/idlist.[ch].
868 * Now actually fixed the nickname changing on disconnection.
869 Added new function silc_change_nick to the Irssi SILC Client.
870 Affected file irssi/src/silc/core/client_ops.c,
871 irssi/src/silc/core/silc-nicklist.[ch].
873 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
875 * Check that the public key exists in the GETKEY command before
876 trying to encode it. Affected file silcd/command.c.
878 * Print some notifications on received public keys with GETKEY
879 command in the Irssi SILC Client. Affected files are
880 irssi/src/fe-common/silc/module-formats.[ch],
881 irssi/src/silc/core/client_ops.c.
883 * Use IDENTIFY command to resolve the server information in the
884 GETKEY command instead of INFO command. Affected file
885 lib/silcclient/command.c.
887 * All command reply functions in the client library now calls
888 the pending command reply callbacks even if an error has
889 occurred. The server has done this a long time and now it was
890 time to move the client library to this as well. Now all
891 errors can be delivered back to the pending command reply
892 callbacks if necessary. Affected files are
893 lib/silcclient/command[_reply].[ch].
895 * Change the nickname on disconnection back to the username
896 because in reconnect the server will enforce it to it anyway.
897 Affected file irssi/src/silc/core/silc-servers.c.
899 * Fixed a config file parsing bug in the Irssi SILC client.
900 Affected file irssi/src/silc/core/clientconfig.c.
902 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
904 * When printing the channel mode on JOIN, verify that the
905 channel key and channel's HMAC are valid. Affected file
906 irssi/src/silc/core/client_ops.c.
908 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
911 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
912 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
914 * Removed channel key rekey task deleting from the function
915 silc_server_save_channel_key. Affected file silcd/server.c.
916 Added explicit timeout task context instead that is used to
917 delete the task if we are registering a new task before the
918 new task has elapsed.
920 * When channel key rekey occurs the client library now saves
921 the old channel key for a short period of time (10 seconds) and
922 is able to use it in case some is still sending channel
923 messages encrypted with the old key after the rekey. Affected
924 file lib/silcclient/[idlist.h|client_channel.c].
926 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Added check to the silc_server_new_id_real to not accept
929 new ID if it is the sender's own ID. Affected file is
930 silcd/packet_receive.c.
932 * Assure that we do not announce ourself or the one we've
933 sending our announcements when we're router and are announcing
934 servers to our primary router. Affected file silcd/server.c.
936 * Fixed silc_server_command_identify_check_client to assemble
937 correct WHOIS packet. It send corrupted WHOIS packet and
938 caused problem with router to router connections. Affected
939 file silcd/command.c.
941 Fixed also silc_server_command_whois_check the same way
942 as for the IDENTIFY command.
944 * Added new SilcIDListStatus to the server in the SilcIDListData
945 structure. The status now includes the current status of
946 the entry (like registered, resolved etc.). Affected file
947 silcd/idlist.[ch]. Defined a bunch of different status types
948 as well. This replaced the old boolean registered field as well.
950 Added resolve_cmd_ident field to the SilcClientEntry structure
951 too so that if the entry is for example being resolved so
952 another command may attach to the same pending command reply
953 without requiring to resolve the same entry again. This concept
954 should optimize the WHOIS and the IDENTIFY resolving under
955 heavy load by taking away unnecessary resolving for entries
956 that are being resolved already.
958 Added support for adding multiple pending commands for one
959 command idenfier. Affected file silcd/command[_reply].[ch].
961 * Fixed WHOIS and IDENTIFY save to remove the cache entry
962 before deleting the data. Otherwise the hash table will have
963 freed data in comparison functions. Affected file is
964 silcd/command_reply.c.
966 * Fixed silc_idlist_replace_client_id to add the new entry to
967 the cache with NULL nickname. Otherwise there will be invalid
968 memory as the nickname after the nickname is freed. Affected
969 file silcd/packet_receive.c.
971 * Fixed the silc_idlist_get_clients_by_hash. The entries was
972 saved into wrong slots because the previous number of entries
973 was not taken into account. Affected file silcd/idlist.c.
974 Fixed same thing in silc_idlist_get_clients_by_nickname too.
976 * If we are router and we receive JOIN notify to a channel that
977 does not have any users then notified client is marked as the
978 channel founder, as it is it. The affected file is
979 silcd/packet_receive.c
981 * Added to the extended hash table API's table_del_*ext functions
982 the destructor as argument too, so that the caller can decide
983 which destructor to use or whether to use destructor at all.
984 Affected file lib/silcutil/silchashtable.[ch].
986 * Fixed ID Cache purging. It actually deleted the entries from
987 the hash table after the data was freed. The hash table ended
988 up comparing freed memory. The affected file is
989 lib/silccore/silcidcache.c.
991 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Fixed Irssi SILC client's KILL command's HELP syntax.
995 * The USERS command now resolves the detailed user information
996 if the userinfo field is missing. Affected file is
997 lib/silcclient/command_reply.c.
999 * Do not print error in silc_file_read if the read file does
1000 not exist. Just silently return NULL. Affected file is
1001 lib/silcutil/silcutil.c.
1003 * Fixed the silc_log_output to not wine about NULL filename
1004 and to not create some bogus " " filename. Affected file is
1005 lib/silcutil/silclog.c.
1007 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Fixed various printing bugs on the user interface in the
1010 Irssi SILC Client. Minor changes that were forgotten from
1013 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Fixed the configure.in.pre and the compilation and distribution
1016 environment to support the new autoconf 2.52. That version is
1017 now required to compile the CVS trunk.
1019 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1022 to generally parse user@fqdn format strings. Affected file
1023 lib/silcutil/silcutil.c.
1025 * Added nickname_format and nickname_force_format fields to the
1026 SilcClientParams structure. The first one defines the format
1027 for the nicknames that the library will enforce if the receives
1028 multiple same nicknames. The second one is boolean value and
1029 can be used to force the library to always enforce the format
1030 to the nicknames regardles whether there are multiple nicknames
1031 or not. This configurable formatting was employed to flexibly
1032 support accessing multiple nicknames from the user interface.
1033 The userinterface can now set the nicknames to what ever format
1034 they prefer. Affected file lib/silcclient/silcapi.h.
1036 Added function silc_client_nickname_format to the file
1037 lib/silcclient/idlist.c. It performs the nickname formatting.
1039 Added new field `hostname´ to the SilcClientEntry context.
1040 It holds the hostname of the client. Affected file is
1041 lib/silcclient/idlist.h.
1043 * Irssi SILC Client sets the nicknames in nick@hostn format.
1044 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1045 irssi/src/silc/core/silc-core.c.
1047 The WHOIS printing now also shows both the real nickname and
1048 the formatted nickname so that user knows how to access the
1049 user if there are multiple same nicknames cached. Affected
1050 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1051 printing formatting too to take the hostname now as a separate
1052 argument. The Affected file is
1053 irssi/src/fe-common/silc/modules-formats.[ch].
1055 * Changed the silc_client_get_clients_local to accept the formatted
1056 nickname as argument. It accepts the real nickname too but the
1057 formatted nickname can be used to find the true entry from
1058 multiple entries. Affected file lib/silcclient/silcapi.h and
1059 lib/silcclient/idlist.c.
1061 * Added nickname_format_parse field to the SilcClientParams.
1062 It is a callback function provided by the application to parse
1063 the nickname out of the formatted nickname string. The library
1064 calls it to get the nickname from the formatted string. Since
1065 the application generally knows better the format of the nickname
1066 string it parses it instead of the library, even though library
1067 encodes the formatted string. If the callback function is not
1068 provided then the library will use the string as is. The
1069 affected file is lib/silcclient/silcapi.h.
1071 * All the nickname strings passed to the client library in
1072 commands are now expected to be formatted nickname strings.
1073 If the command does not support the formatted nickname string
1074 it will assume that the sent string is the actual nickname.
1075 Affected file lib/silcclient/command.c.
1077 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Added public key authentication support to OPER and SILCOPER
1080 commands in the client library. Affected file is
1081 lib/silcclient/command.c.
1083 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Changed the get_auth_methdod client operation to be asynchronous.
1086 It can be async if the application resolves the authentication
1087 method from the server during the negotiation. Added new
1088 SilcGetAuthMeth completion callback that the application will
1089 call after resolving the authentication method.
1091 Added function silc_client_request_authentication_method that
1092 the application can use to resolve the authentication method
1093 from the server. Added also SilcConnectionAuthRequest callback
1094 that the library will call after the server has replied. The
1095 application can call this function if it does not know the
1096 current authentication method.
1098 Affected files are lib/silcclient/client.c and
1099 lib/silcclient/silcapi.h.
1101 * The Irssi SILC client now automatically resolves the authentication
1102 method incase any configuration information is not present (and
1103 currently there never is). The affected file is
1104 irssi/src/silc/core/client_ops.c.
1106 * Fixed public key authentication from the client library.
1107 Affected file lib/silcclient/protocol.c. Changed also the
1108 protocol specification about the public key authentication in
1109 the connection authentication protocol. The actual data to be
1110 signed is now computed with a hash function before signing.
1112 * Fixed the public key authentication from the server as well.
1113 Affected file silcd/protocol.c.
1115 * Removed the mlock()'s from the memory allocation routines.
1116 Affected file lib/silcutil/silcmemory.c. The ./configure does
1117 not check anymore for the mlock(). Affected file is
1120 * Fixed USERS command in server to allow the execution of the
1121 command for private and secret channels if the client sending
1122 the command is on the channel. Affected file silcd/command.c.
1124 * Fixed silc_client_get_clients_local to return the clients
1125 count correctly. It could return wrong value. Affected file
1126 lib/silcclient/idlist.c.
1128 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1131 types. The assembler optimizations seemed not to like 64-bit
1132 data types. The assmebler optimizations thus are now enabled
1133 also for BSD systems as opposed to only enable them for Linux.
1135 * Do not check for threads at all on BSD systems. Affected
1136 file configure.in.pre.
1138 * Removed -n and -h options from the Irssi SILC Client since
1139 they are not used in silc.
1141 * Fixed the prime generation to assure that the first digit
1142 of the generated random number is not zero since our conversion
1143 routines does not like number strings that starts with zero
1144 digit. If zero digit is seen the random number is regenerated.
1145 This caused some corrupted RSA keys when the zero first digit
1146 was met. Affected file lib/silcmath/silcprimegen.c.
1148 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * Fixed WIN32 configuration in the ./configure script.
1151 Fixed to include xti.h on environments that has it.
1152 Patches by Carsten Ilchmann and andrew.
1154 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1156 * Changed the silc_id_create_client_id to be collision
1157 resistant. It is now assured that there cannot be created
1158 two same client ID's. I suspect that some weird bugs in
1159 the server were actually caused by duplicate Client IDs.
1160 Affected file silcd/serverid.[ch]. A router receiving
1161 new ID now also assures and informs the sending server
1162 if the ID caused collision.
1164 * Changed the silc_id_create_channel_id to also assure that
1165 there are no collisions.
1167 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Statement about ignoring the Mutual Authentication flag when
1170 performing rekey with PFS was a bit misleading. It is ignored
1171 if it was set in the initial negotiation, it cannot be even
1172 set in the rekey. Fixed in the ke-auth draft. Started the
1173 new versions of the protocol drafts in the doc/.
1175 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * Fixed a bug in silc_client_command_identify_save when saving
1178 new channel information. The channel name was no duplicated
1179 and caused crash on exit. Affected file is
1180 lib/silcclient/command_reply.c.
1182 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1184 * Fixed the getkey command handling in the server. Send just
1185 empty OK reply to the sender if the key could not be fetched
1186 (but everything else was ok, like the key just was not available).
1187 Changed the public key parameter to optional in the protocol
1188 specs so that empty OK reply can be sent. Affected file
1191 Added a message to Irssi SILC client to tell to user if the
1192 server did not return a public key.
1194 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Fixed a channel key regeneration bug. It registered new
1197 timeout tasks exponentially until all system resources were
1198 used. Affected file silcd/server.c.
1200 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Added the SILC Document generator to the scripts/silcdoc.
1203 It can be used to generate the Toolkit Reference Manual out
1204 of the source tree. Internally it will also use the RoboDoc
1205 generator now imported in util/robodoc.
1207 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Added couple of return's in rekey protocol if error orccurred
1210 during the protocol. The execution must be terminated.
1211 Affected file silcd/protocol.c. Also, terminate the protocol
1212 always with timeout.
1214 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1216 * The client's Client ID was created initally from the wrong
1217 nickname (it could have been in format nick@host) in the
1218 silc_server_new_client. Affected file silcd/packet_receive.c
1220 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Added some SILC_LOG_ERROR's to various error conditions
1223 if client could not be added to ID cache. Affected files
1224 silcd/packet_receive.c and silcd/server.c.
1226 * When client's sock->user_data is freed, NULL also the
1227 client->router and client->connection pointers. Added check
1228 for these pointers being NULL to various places around the
1229 code. Affected file silcd/server.c.
1231 * Added client->data.registered == TRUE checks to various
1232 places around the code to assure that unregistered client's
1233 are not handled when it is not allowed. Affected file
1236 * Added `bool registered' fields to all
1237 silc_idlist_[server|client]_get_* routines to indicate whether
1238 the fetched client needs to be registered or not. Affected
1239 file silcd/idlist.[ch].
1241 * Add your own entry as registered to the ID cache in the
1242 server. Affected file server.c.
1244 * Fixed a bug in silc_server_new_server. The SilcServer was
1245 set as the new server's context instead of SilcServerEntry.
1246 This naturally caused some weird bugs.
1248 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Do not delete the channel rekey task when adding it
1251 for in silc_server_create_channel_key.
1253 * Changed the silc_server_create_channel_key to return
1254 TRUE or FALSE to indicate the success of the channel key
1257 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1259 * Fixed MSVC++ project files and added missing files to
1260 Makefiles under win32/.
1262 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1264 * Do not add TCP_NODELAY flag if the operating system
1265 does not have it defined. Affected files are
1266 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1268 * Fixed buffer overflow from Irssi SILC Client. Affected
1269 file irssi/src/fe-common/core/themes.c.
1271 * Fixed double free in client library in the file
1272 lib/silcclient/client.c when disconnecting from server.
1274 * Applied double free patch from cras to Irssi SILC client.
1275 Affected files irssi/src/core/[modules/expandos].c
1277 * Fixed the disconnection handling to Irssi SILC Client.
1278 The application must call silc_client_close_connection
1279 in ops->connect client operation in case of failure of
1280 the connection. Affected file is
1281 irssi/src/silc/core/client_ops.c.
1283 * Do not set sock->protocol to NULL in the function
1284 silc_client_close_connection after executing the protocol's
1285 final callback since the sock might not be valid anymore.
1286 Affected file lib/silcclient/client.c.
1288 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Do not enable SILC_THREADS if the linking with libpthread
1291 did not happen. Affected file configure.in.pre.
1293 * Added notion to protocol specification that server must
1294 verify the sent authentication payload with CMODE when
1295 setting the channel founder key. Implemented it to the
1296 server. Affected file silcd/command.c.
1298 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Added _EXTRA_DIST SILC distribution variable to the
1301 distributions file. It is used to conditionally add extra
1302 files or directories to the specific distribution. Affected
1303 files ./prepare, Makefile.am.pre and distributions.
1305 Removed the `_' from the start of the distribution names.
1308 * Added README.WIN32 for instructions to compile the Toolkit
1311 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Fixed a double free in disconnection in the server. Affected
1314 file is silcd/server.c.
1316 * Fixed the lib/silcske/groups.c to work now also with GMP
1317 MP library. The string conversion did not work when using
1318 specific base and the base is indicated in the string as well.
1320 * Created win32/ directory which now includes MSVC++ specific
1321 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1322 It will appear only in the toolkit distribution
1324 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Changed the key material distribution function in case when
1327 the hash output is too short. The data is now concatenated
1328 a bit differently than it used to. Made the change to the
1329 SKE protocol specification.
1331 * Added better GMP detection to configure.in.pre. A patch
1334 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Fixed a minor bug in SKE that might cause some problem on
1337 some platforms. Affected file lib/silcske/silcske.c.
1339 * Added the cookie checking for initiator in the SKE. It checks
1340 that the responder returns the sent cookie unmodified. The
1341 affected file is lib/silcske/silcske.c. Added new SKE
1342 error type INVALID_COOKIE that can be sent during the
1343 negotiation. Fixed some memory leaks as well.
1345 * Added the "invalid cookie" error message to Irssi SILC client's
1348 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Added `task_max' field to the SilcClientParams to indicate
1351 the maximum tasks the scheduler can handle. If set to zero,
1352 default values are used. Affected file lib/silcclient/silcapi.h.
1354 * Fixed memory leaks in silc_client_close_connection. Affected
1355 file lib/silcclient/client.c.
1357 * Added silc_client_del_client_entry to client library to free
1358 all memory of given client entry. Affected file is
1359 lib/silcclient/idlist.[ch].
1361 * Added new functions silc_client_del_channel and
1362 silc_client_del_server to delete channel and server entries.
1363 Affected file lib/silcclient/[silcapi.h/idlist.c].
1365 * Removed silc_client_del_client_by_id from silcapi.h.
1367 * Fixed the INFO command to return the server's own info
1368 correctly when querying by Server ID. Affected file is
1371 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Removed the non-blocking settings in WIN32 code in the
1374 silc_sock_[read/write] and added SleepEx instead. Affected
1375 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1376 of input data is now checked with FIONREAD and ioctlsocket.
1378 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Call silc_schedule_task_del_by_context in the
1381 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1382 Affected file lib/silccore/silcprotocol.c.
1384 * Call silc_protocol_cancel for active protocols in the
1385 silc_server_close_connection if the funtion
1386 silc_server_free_sock_user_data has not been called.
1387 Affected file silcd/server.c.
1389 * Generic tasks cannot be deleted using the del_by_fd
1390 task deleting function since generic tasks does not match
1391 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1393 * Added a notion to SILCOPER help file that the SILCOPER works
1394 only on router server, not on normal server.
1396 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Added for WIN32 support for the new scheduler as well.
1399 Affected file lib/silcutil/win32/silcwin32schedule.c.
1401 * Fixed the SHA1 implementation to work on various platforms.
1403 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1406 API. It is part of the scheduler now. Everything else is
1407 as previously but some functions has changed their names.
1408 Checkout the lib/silcutil/silcschedule.h for the interface.
1409 Updated all applications to use the new interface. Affected
1410 files are lib/silcutil/silcschedule.[ch].
1412 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Found a bug in the SKE implementation. The HASH value,
1415 specified by the protocol, was not computed correctly. The
1416 public key of the responder was not added to the computation
1417 even though it is mandatory. Affected file lib/silcske/silcske.c.
1418 This unfortunately causes incompatibilities with older
1419 clients and servers.
1421 * Added WIN32 specific network init and uninit functions:
1422 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1423 the Winsock2. Affected file lib/silcutil/silcnet.h and
1424 lib/silcutil/win32/silcwin32net.c.
1426 * Set the socket always to nonblocking mode on WIN32 after
1427 reading data or writing data. Affected file is
1428 lib/silcutil/win32/silcwin32sockconn.c.
1430 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Fixed various compilation problems under WIN32. Affected
1433 files lib/silcutil/win32/silcwin32thread.c and
1434 lib/silcutil/win32/silcwin32schedule.c.
1436 * Removed all _internal.h #includes from public header
1437 files. Internal headers must never be included from
1440 Removed also the lib/silcske/payload_internal.h file.
1442 * All include files that may be needed (public and some others
1443 included by the public headers) by application developers are
1444 now copied to the ./includes directory. It does not copy any
1445 internal headers. Affected file Makefile.defines.pre and all
1446 Makefile.am's under lib/ and subdirs.
1448 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Do not change the ~/.silc directory's permissions automatically.
1451 Affected file irssi/src/silc/core/clientutil.c.
1453 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1455 * Do not cancel the protocol in silc_server_close_connection
1456 it might cause recursion. Now cancelled in the function
1457 silc_server_free_sock_user_data. Affected file silcd/server.c.
1459 * Fixed the silc_server_remove_clients_by_server to regenerate
1460 the channel keys correctly finally. Added also new function
1461 silc_server_remove_clients_channels to actually do it.
1462 Affected file silcd/server.c.
1464 * Fixed the silc_server_new_channel to not crash by giving
1465 wrong router to the new channel. Affected file is
1466 silcd/packet_receive.c.
1468 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1471 which is given as argument to the silc_client_alloc now.
1472 It can be used to configure the client and set various parameters
1473 that affect the function of the client.
1475 * The USERS command in server did not check whether the channel
1476 is private or secret. Affected file silcd/command.c.
1478 * Added new argument to the USERS command in protocol specification.
1479 The USERS command now can take the channel name as argument
1480 as well. Added support for this in client and server and
1481 updated the protocol specs.
1483 * Completed the GETKEY command in client. It can be now used
1484 to fetch also servers public key not only some clients.
1485 Affected files lib/silcclient/command[_reply].c.
1487 * Added silc_client_get_server to return server entry by the
1488 server name. Affected files lib/silcclient/silcapi.h and
1491 * Redefined the IDENTIFY command in protocol specification to be
1492 more generic. It now can be used to query information about
1493 any entity in the SILC Network, including clients, servers and
1494 channels. The query may be based either the entity's name
1495 or the ID. Added support for this in both client and server.
1497 Affected files silcd/command.c and lib/silcclient/command.c
1498 and command_reply.c.
1500 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1501 the _from_client and _from_server functions. Affected file
1504 * Added silc_client_get_channel_by_id_resolve to the file
1505 lib/silcclient/silcapi.h to resolve channel information by
1506 its ID. Added also silc_client_get_channel_by_id that
1507 does not resolve it from the server.
1509 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Added SilcServerEntry context into the client library
1512 to represent one server. The INFO command now allocates
1513 these to save the resolved server info. For now on the
1514 client library will also keep information about servers,
1515 connected and resolved with INFO.
1517 The INFO command now allocates the SilcServerEntry context
1518 and saves the server info there. The COMMAND_REPLY in
1519 the INFO now returns the parameters to application in
1520 same order as defined in the protocol specification.
1522 The entries are cached in the client->server_cache.
1524 * The INFO command is now issued after received the Client ID
1525 from the server. Affected file lib/silcclient/client.c.
1527 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1528 to the application as the mode changer might be server.
1529 It is guaranteed that NULL is not returned anymore to the
1530 application. Affected file lib/silcclient/client_notify.c.
1532 The ID Type is now also passed to the application so that
1533 it can check whether the returned entry is SilcClientEntry
1536 Added new function silc_client_get_server_by_id to return
1537 the server entry by ID. Affected files are the
1538 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1540 * Do not create the channel in the Irssi SILC Client when issuing
1541 the JOIN command but when received the sucessful JOIN command
1542 reply. Otherwise the channel might get created even though we
1543 could not join it. The Affected file is
1544 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1546 * Fixed a channel joining bug in router. The router must also
1547 check the channel modes, invite and ban lists etc. when serving
1548 the JOIN command sent by normal server. Affected file is
1549 silcd/command.c. The router now resolves the client's
1550 information from the server who sent the JOIN command if it
1551 does not know it, and processes the JOIN command only after
1554 * Changed the SilcCommandCb to take new argument; void *context2.
1555 Affected file lib/silccore/silccommand.h
1557 The second argument in the command callbacks in the server now
1558 includes the SilcServerCommandReplyContext if the command was
1559 called as pending command callback from the command reply.
1560 Otherwise it is NULL. When called as pending the status of the
1561 command reply will be checked and if it was erronous the
1562 error will be sent to the original sender of the command.
1563 This way the client always receives the error messages even
1564 though the server was actually the one who received the error
1565 when it resent the command to router, for example. Affected
1566 files silcd/command[_reply].[ch].
1568 * Fixed sending WHOWAS command's error message to client if
1569 the requested client could not be found. It was missing.
1572 * Changed the CMODE and CUMODE commands reply arguments in the
1573 protocol specification. The Channel ID is now sent in both
1574 of the commands to identify the channel. Implemented this
1575 new feature to the client and server. Affected files
1576 lib/silcclient/command_reply.c and silcd/command.c.
1578 * Made better checks for invite and ban lists in the JOIN
1579 command in server. Affected file silcd/command.c.
1581 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * The server now performs the incoming host IP/DNS lookup
1584 using the silc_socket_host_lookup and thus does not block
1585 the server anymore. Affected file silcd/server.c.
1587 * Completed the multi-thread support for SILC Scheduler in
1588 the lib/silcutil/silcschedule.c.
1590 * Fixed the configure.in.pre to detect the pthread correctly
1593 * Fixed a deadlock in silc_task_queue_wakeup in the file
1594 lib/silcutil/silctask.c.
1596 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Added new function silc_schedule_wakeup that is used in
1599 multi-threaded environment to wakeup the main thread's
1600 schduler. It needs to be used when a thread adds a new task
1601 or removes a task from task queues. After waking up, the
1602 scheduler will detect the task queue changes. If threads
1603 support is not compiled in this function has no effect.
1604 Implemented the wakeup mechanism to both Unix and WIN32
1605 systems. Affected files are lib/silcutil/silcschedule.[ch],
1606 lib/silcutil/unix/silcunixschedule.c and the
1607 lib/silcutil/win32/silcwin32schedule.c.
1609 * Added new function silc_task_queue_wakeup to wakeup the
1610 scheduler by the specified task queue. Affected file
1611 lib/silcutil/silctask.[ch].
1613 * The silc_socket_host_lookup_start now wakes up the scheduler
1614 after adding the timeout task. Affected file is
1615 lib/silcutil/silcsockconn.c.
1617 * The silc_socket_host_lookup is synchronous now if the threads
1618 support is not compiled in. However, the callback is still
1619 called asyncronously through the scheduler, anyway. Affected
1620 file lib/silcutil/silcsockconn.c.
1622 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Added new function silc_socket_host_lookup to perform
1625 asynchronous IP and FQDN lookups for the socket connection.
1626 Affected files lib/silcutil/silcsockconn.[ch].
1628 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1631 that may or may not compile the mutex support in.
1633 Changed the silc_mutex_alloc interface. It allocates the
1634 mutex now to the sent pointer and returns TRUE or FALSE.
1636 Affected file lib/silcutil/silcmutex.h.
1638 * Wrote the SILC Task Queue interface to support multi-threads.
1639 Affected file lib/silcutil/silctask.[ch].
1641 * Wrote the SILC Scheduler to support multi-threads. Affected
1642 file lib/silcutil/silcschedule.c.
1644 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1647 in lib/silcutil/win32/.
1649 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * Defined SILC Mutex API and SILC Thread API and implemented
1652 them for Unix. Affected files are
1653 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1654 lib/silcutil/unix/silcunixmutex.c and
1655 lib/silcutil/unix/silcunixthread.c.
1657 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Fixed the silc_server_remove_clients_by_server's channel
1660 key re-generation. The hash table handling was incorrect
1661 and would not work with many channels. Affected file is
1664 * Fixed some memory leaks around the server code.
1666 * Rewrote the silc_server_get_users_on_channel to support IPv6
1667 based Client ID's. Affected file silcd/server.c.
1669 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1670 specification. However, a separate document must be written
1671 to define the detailed signing procedure and the payload
1672 associated with the flag. Defined the flag to the
1673 lib/silccore/silcchannel.h as well.
1675 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Changed the dynamic tables to static size tables in the
1678 lib/silccrypt/silchmac.c.
1680 * Removed GCC dependencies from the code. A patch by cras.
1682 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1684 * Do not show the error "Error receiving packet bla bla"
1685 in server if it really was not an error (-2 means that reading
1686 is pending). Affected file silcd/server.c.
1688 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Fixed a possible crash in silc_server_remove_clients_by_server
1691 in silcd/server.c. Fixed there also some memory leaks.
1693 * Fixed the silc_idlist_replace_client_id. It could replace
1694 wrong key in the hash table. Affected file silcd/idlist.c.
1696 * Do not check whether there are global users on the channel
1697 if the channel->global_users is FALSE. Affected functions
1698 silc_server_remove_from_one_channel and
1699 silc_server_remove_from_channels in silcd/server.c. Also,
1700 do not check if the removed client is local as we can be
1701 sure that global client was not removed from the channel
1702 and checking for global users is not needed.
1704 * The silc_server_remove_clients_by_server now re-generates
1705 the channel keys correctly for those channels that had
1706 clients removed from them. Affected file silcd/server.c.
1708 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Found the reason of random crashes in the server. We weren't
1711 ignoring the SIGPIPE signal (which can be sent in write())
1712 and it crashed the server. Affected file silcd/silcd.c.
1714 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Assure that sock->user_data is not NULL in the function
1717 silc_server_packet_send in silcd/packet_send.c.
1719 * Disconnect the remote connection if it could not be added
1720 to any ID lists in the server. The affected file is
1723 * Check in silc_server_packet_send[_real/dest] that the
1724 socket is not disconnecting and ignore the data if it is.
1725 Affected file silcd/packet_send.c.
1727 * Define inline to __inline on native WIN32 compilation.
1728 Affected file includes/silcwin32.h.
1730 * Added some explicit type casts for inline code since MSVC
1731 require them. Affected files lib/silcutil/silcbuffer.h,
1732 lib/trq/silcdlist.h and lib/trq/silclist.h.
1734 * Print warning in log files from now on if the packet
1735 decryption fails. Affected file silcd/server.c.
1737 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Changed the `say' client operation's interface to accept
1740 new `type' argument to indicate the type of the message sent
1741 by the library. The application may filter the library's
1742 messages according the type. The affected file is the
1743 lib/silcclient/silcapi.h.
1745 * Added two new functions to lib/silcclient/silcapi.h:
1746 silc_client_del_client and silc_client_del_client_by_id.
1747 Affected file lib/silcclient/idlist.c.
1749 * Moved the clientincludes.h from includes/ to silc/ and
1750 serverincludes.h from includes/ to silcd/.
1752 * The modes for the CMODE and CUMODE are now passed as
1753 uint32 for application with COMMAND_REPLY. The affected
1754 file is lib/silcclient/command_reply.c.
1756 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * /WHOIS without arguments shows client's own information.
1759 Affected file lib/silcclient/command.c.
1761 * Changed PING to not accept any arguments. The specs
1762 says that client can ping only the connected server so
1763 requiring an argument is not needed. Affected file is
1764 lib/silcclient/command.c.
1766 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Fixed a fatal bug in private message sending and reception
1769 encryption and decryption when using private message keys.
1770 The implementation was incorrect and did not follow the
1771 specification. It causd that some of the message were
1772 lost since it did not use the sending and receiving keys
1773 as the protocol suggests. This has been fixed and will cause
1774 incompatibilities with older clients when sending private
1775 message encrypted with private message keys. Affected files
1776 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1777 and various other in Irssi SILC Client.
1779 Added `responder' boolean argument to the functions
1780 silc_client_add_private_message_key[_ske] to indicate when
1781 the key is added as responder or initiator of the key
1784 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Removed the silc_ske_check_version function and created
1787 a SilcSKECheckVersion callback. Added also a function
1788 silc_ske_set_callbacks that is now used to set all SKE
1789 callbacks. The callback functions are not given to
1790 the SKE functions anymore, but this function is used to
1793 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1795 * Added `silc_version' argument to the silc_client_alloc
1796 to define the version of the application for the library.
1797 The library will use the version string to compare it
1798 against the remote host's (usually a server) version
1799 string. Affected file lib/silcclient/silcapi.h
1801 * Added the KE protocol context to Key Agreement context
1802 in client library so that we can abort the SKE if it
1803 is in process when we get timeout. Affected file is
1804 lib/silcclient/client_keyagr.c.
1806 * Do not resolve the client ID forever if it returns in the
1807 first time that such client does not exist. This was done
1808 for example with private message. Affected file is
1809 lib/silcclient/client_prvmsg.c.
1811 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Do not add regex.h for WIN32. The affected file
1814 includes/silcincludes.h.
1816 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1817 not work yet 100%. It generates the DLL's automatically
1818 when compiling with --with-win32 under cygwin.
1820 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * lib/contrib/regex.c is not compiled on WIN32.
1824 * Added silc_net_get_socket_opt function to the
1825 lib/silcutil/silcnet.h.
1827 * Added includes/silcwin32.h for WIN32 specific includes
1830 * Do not use ptime structure or any of the posix process
1831 functions on WIN32 in lib/silccrypt/silrng.c.
1833 * Added silc_gettimeofday to provide generic function
1834 for struct timeval on all platforms. Added the function
1835 to lib/silcutil/silcutil.h.
1837 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1840 library as they clearly belong there. As a plus side we
1841 can make the actual socket connection routines platform
1844 Added also new generic function silc_socket_read and
1845 silc_socket_write (that used to be silc_packet_[read/write].
1846 The implementation of these are platform specific.
1848 * Added WIN32 specific routines of silc_socket_[read/write]
1849 to lib/silcutil/win32/silcwin32sockconn.c.
1851 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Added preliminary support for native WIN32 compilation under
1854 cygwin (using the -mno-cygwin option for GCC) to the
1855 ./configure.in.pre. The --with-win32 now prepares the
1856 compilation for native WIN32.
1858 * Rewrote the SILC Scheduler interface in the file
1859 lib/silcutil/silcschedule.h. The scheduler is now context
1860 based and does not have anymore any global static scheduler.
1861 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1862 and created lib/silcutil/win32 directory for WIN32 based
1865 * Added Unix specific network routines to the
1866 lib/silcutil/unix/silcunixnet.c and the old
1867 lib/silcutil/silcnet.c includes now only generic routines.
1869 Added WIN32 specific network routines to the
1870 lib/silcutil/win32/silcwin32net.c.
1872 * Added Unix specific utility functions from the
1873 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1875 * Added WIN32 SILC Scheduler to the file
1876 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1879 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Do not handle JOIN notify in the server if the target client
1882 is not registered (idata->registered == FALSE). The affected
1883 file is silcd/packet_receive.c.
1885 * Update the nickrec->founder in event_cumode in the Irssi SILC
1886 client. Affected file irssi/src/silc/core/silc-channels.c.
1888 * Fixed the CUMODE_CHANGE notify handling in the server when
1889 server and router are announcing their clients on channels.
1890 Now the mode changes are saved and notified correctly. The
1891 affected file is /silcd/packet_receive.c.
1893 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1894 They really did not replace the cache entry in the ID Cache.
1895 Now they do that. Affected file silcd/idlist.c.
1897 * Fixed the KICK notify handling in the Irssi SILC client to
1898 update the channel records so that the kicked client does not
1899 appear to be on the channel. The affected file is
1900 irssi/src/silc/core/silc-channels.c.
1902 * Always update the conn->current_channel when executing command
1903 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1905 * Fixed the KILL notify handling in Irssi SILC client to remove
1906 the killed client on all channels.
1908 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Fixed the silc_parse_command_line to remove extra spaces
1911 from the start and end of the arguments. Affected file is
1912 lib/silcutil/silcutil.c.
1914 * Cancel and free any active protocol in the function
1915 silc_server_close_connection. Affected file silcd/server.c.
1917 * Cancel and free any active protocol in the function
1918 silc_client_close_connction. Affected file is
1919 lib/silcclient/client.c.
1921 * Do not execute the KILL command for clients that are in
1922 history (ie. they are not in the network). Affected file is
1925 * Fixed KILL notify handling, client does not crash anymore.
1926 Affected file irssi/src/silc/core/silc-channels.c.
1928 * Reduced the default packet buffer size from 2048 to 1024 in
1929 lib/silccore/silcpacket.c.
1931 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1932 counter to the SKE context that is incresed when the SKE library
1933 performs async operation outside the library. If the outside
1934 process frees the SKE context and FREED status will be set
1935 and the library will detect after the sync operation that the
1936 libary is freed. The affected files are
1937 lib/silcske/silcske[_status].[ch].
1939 * Resolve the client entry information in the function
1940 silc_client_channel_message to assure that NULL pointer is not
1941 passed as client entry to the application. */
1943 * Fixed the task timeout calculation to assure that there is
1944 never negative timeouts. The affected file is
1945 lib/silcutil/silcschedule.c.
1947 * Fixed the channel user mode notification sending in server.
1948 It was sent point-to-point to the router (or to server by router)
1949 but it needs to be destined to a channel. The routines now
1950 supports sending the channel user mode notifys to the channels
1951 when announcing clients and channels. Affected files are
1952 silcd/server.c and silcd/packet_receive.c.
1954 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1955 It did not actually replace the old channel entry in the cache.
1956 Affected file lib/silcclient/client_notify.c.
1958 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Fixed a possible crash in silc_packet_send_prepare. It now
1961 assures always that there is enough space in the buffer and
1962 at the tail area of the buffer (for MAC).
1964 Fixed the inbound buffer reallocation in silc_packet_read.
1965 It was old code and did not handle the reallocation correctly.
1968 The affected file is lib/silccore/silcpacket.c.
1970 * Fixed buffer overflow in silc_parse_nickname in the file
1971 lib/silcutil/silcutil.c.
1973 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * make install generates new server keys only if there is not
1978 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1980 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1981 Added check that if the NOREPLY is set then we will not send
1982 the away message. This avoids infinite loop of away messages
1983 if both clients are away. The affected file is
1984 lib/silcclient/client_prvmsg.c.
1986 * Fixed client crash if /NICK was given without arguments.
1987 Affected file lib/silcclient/command.c.
1989 * Server does not send the invite list in INVITE command back
1990 to the client if the list was not altered. Added this notion
1991 to the protocol spec as well. Affected file silcd/command.c.
1993 Fixed possible crash in INVITE command by checking the
1994 value of silc_server_get_client_route command.
1996 * Fixed the INVITE notify type handling. The arguments are now
1997 taken in correct order and client does not crash. The affected
1998 file is irssi/src/silc/core/silc-channels.c.
2000 Removed the "Inviting xxx to channel" message from the
2001 client library away and let the application handle it.
2002 Affected file lib/silcclient/command.c. Added that message
2003 to Irssi SILC client's message formats.
2005 * Fixed CMODE command crash in client. It now checks the
2006 amount of arguments correctly and does not crash. The affected
2007 file is lib/silcclient/command.c.
2009 * Do not create new channel automatically in silc_channels_join
2010 but check whether the channel by that name already exists.
2011 Affected file irssi/silc/core/silc-channels.c.
2013 * Do not send the SERVER_SIGNOFF to router if the disconnected
2014 entity was the router. Affected file silcd/server.c.
2016 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2017 SILC client as it was missing from there.
2019 Added the handling of the KICK notify to the Irssi SILC client
2020 as it was missing. Added "you have been kicked" message to
2021 Irssi SILC client's message modules formats.
2023 Added the handing of the KILL notify to the Irssi SILC client
2024 as it was missing. Added the kill message module formats
2027 The affected file is irssi/src/silc/core/silc-channels.c.
2029 * The router did not save the channel mode the server announced.
2030 Affected file silcd/packet_receive.c.
2032 * Fixed a possible crash in INFO command in server. If the
2033 server did not provide the server info it crashed. Affected
2034 file silcd/command.c.
2036 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Fixed the GETKEY command in the server to check also the
2039 global list. Otherwise the GETKEY would not work correctly
2040 in normal SILC server. Affected file silcd/command.c.
2042 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Fixed GETKEY crash, it crashed if the command did not succseed.
2046 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2049 is now real and not just an macro interface to GMP.
2051 Removed the entire GMP from the source tree and imported new
2052 NSS MPI library instead. Reason for removing GMP is that it is
2053 extremely large and compiles extremely slow. The NSS MPI
2054 is only a few files and compiles in less than 10 seconds.
2055 The speed is also about the same as GMP. The MPI is imported
2056 to lib/silcmath/mpi.
2058 If the system has GMP installed we will still use the GMP.
2059 If it is not then the NSS MPI will be compiled.
2061 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Merged a long nickname (127 characters long) crash bugfix from
2064 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2066 * Merged a freed memory reference bugfix from Irssi CVS tree.
2067 Affected file irssi/src/core/commands.c.
2069 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Added the server's public key sving and verification to the
2072 server when performing the SKE. This was missing and the
2073 remote server's (or router's) public key was accepted without
2074 checking whether we have it previously or trust it at all.
2075 Affected file silcd/protocol.c.
2077 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Check in the silc_server_timeout_remote if protocol is active
2080 and make sure that the protocol's final callback is called so
2081 that all memory if freed. Affected file silcd/server.c.
2083 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * silc_server_whois_send_reply crashed the server if the nickname
2086 was 127 characters long. Affected file silcd/command.c.
2088 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added sanity check to the silc_server_new_client. If the hostname
2091 is provided inside username then check that the provided hostname
2092 really is the same as the resolved one. If the hostname was not
2093 resolved then check it from the public key. Affected file is
2094 silcd/packet_receive.c.
2096 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2097 if the server disconnected us and the connection is not valid
2098 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2100 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2101 the library to the lib/silcutil/silcutil.[ch].
2103 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * Close log file after open. Affected file
2106 lib/silcutil/silclog.c.
2108 * Check whether sock == NULL in silc_client_send_packet and return
2109 if it is. Affected file lib/silcclient/silcclient.c.
2111 * Check rec->entry == NULL in the Irssi SILC Client before
2112 sending the channel message. Affecte file is
2113 irssi/src/silc/core/silc-servers.c.
2115 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Merged a splitted window bugfix from Irssi CVS tree. The
2118 affected file is irssi/src/fe-text/textbuffer-view.c.
2120 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2121 It did not print nickname.
2123 * Improved the distributions system a bit.
2125 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2128 irssi/src/fe-text/gui-window.c.
2130 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2131 to in-active server. The affected file is
2132 irssi/src/silc/core/client_ops.c.
2134 * Resolve the client in USERS command reply if the entry does
2135 not have username resolved. The affected file is
2136 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2137 command to WHOIS command to really resolve stuff. The USERS
2138 is not used any more in any critical section so WHOIS can
2139 be used even though it might be slower than IDENTIFY.
2141 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2144 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2146 * Changed the protocol API a bit more consistent in the
2147 lib/silccore/silcprotocol.[ch].
2149 * Changed the following headers to ROBODoc format:
2151 lib/silccore/silcpayload.h
2152 lib/silccore/silcprotocol.h
2153 lib/silccore/silcsockconn.h
2155 All core library headers are now formatted.
2157 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2159 * Fixed a bug in Irssi SILC client; do not show that you are
2160 server/router operator if you really are not. Affected file is
2161 irssi/src/silc/core/client_ops.c.
2163 * Renamed silc_command_free_payload to silc_command_payload_free.
2164 Affected file lib/silccore/silccommand.h
2166 * Added silcmath.h to include the prototoypes of various routines
2167 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2170 * Changed the following headers to ROBODoc format:
2172 lib/silccore/silcchannel.h
2173 lib/silccore/silccommand.h
2174 lib/silccore/silcid.h
2175 lib/silccore/silcidcache.h
2176 lib/silccore/silcmode.h
2177 lib/silccore/silcnotify.h
2178 lib/silccore/silcpacket.h
2179 lib/silcmath/silcmath.h
2181 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Added checking to the server code not to start the server if
2184 ciphers and stuff are not configured properly. Affected files
2185 silcd/serverconfig.[h] and silcd/server.c.
2187 * Changed the layout of the header files of the public interfaces
2188 in the SILC libraries. The new layout supports ROBODoc
2189 documentation tool (and some others) so that it is easy to create
2190 a library reference manual. All the other headers and source
2191 code must still follow the CodingStyle document. Also source
2192 code must not include these ROBODoc stuffs, only the headers.
2193 Furthermore, all public interface headers must now be named
2194 by using `silc' prefix, example: silcapi.h, silccipher.h.
2195 Some files were renamed due to this. All the other headers
2196 must not be used as public interfaces. I will update the
2197 CodingStyle document later. Changed following headers, so far:
2199 lib/silcclient/silcapi.h
2200 lib/silccore/silcauth.h
2201 lib/silccore/silcprivate.h
2202 lib/silccrypt/silcdh.h
2204 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Removed silc_client_packet_send_flush from the client library
2209 as it is not needed. Affected file lib/silcclient/client.[ch].
2211 * Added printing of message of unresolved authentication method
2212 to the Irssi SILC client. Added it to the module formats.
2213 Removed the same message from the client library.
2215 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Added new distribution feature, DISTLABEL. Every distribution
2218 can define own preprocessor label that can be used in the
2219 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2220 file distributions, acconfig.h.pre and prepare.
2222 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Added Makefile.defines_int to include the actual definitions
2225 for Makefile.defines.in. Tested the new distribution system,
2226 created distributions and tested installation.
2228 * Added AWAY message printing to the Irssi SILC client. Added
2229 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2231 * Added SCONNECT command to call the SILC's CONNECT command.
2232 Cannot use CONNECT directly since Irssi uses that internally.
2233 Affected file irssi/src/silc/core/silc-servers.c.
2235 Added ACTION local command. It is same as ME command but takes
2236 the channel as mandatory argument.
2238 Rewrote some of the Irssi's help files to suite for SILC
2241 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Added Makefile.defines[.in] that should for now on be included
2244 in all Makefile.am file in the source tree. That file includes
2245 all common compilation definitions for SILC source tree.
2247 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Minor changes to the ./prepare script to change the package
2250 name according the distribution name to the configure.in.
2252 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Created new distribution system. Added file `distributions'
2255 that defines all the distributions that can be created out of
2256 the SILC source tree. The ./prepare script now reads that
2257 file to determine how to prepare the distributions. The
2258 first argument to the ./prepare is the name of the distribution
2259 and second is the version of the distribution. If given
2260 without arguments it creates the default (toolkit) distribution
2261 with the default version (defined in ./prepare).
2263 All Makefile.am files that are subject to the distributions
2264 are now named as Makefile.am.pre. These are ./Makefile.am
2265 and lib/Makefile.am. Others may be changed later.
2267 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2269 * Added invite list, ban list, some key management and connection
2270 error message printing to module formats in the Irssi SILC client.
2272 * Added new silc_client_set_away_message to set the away message
2273 that is back to the person who sent private message. The
2274 affected file lib/silcclient/silcapi.h and the
2275 lib/silcclient/client_prvmsg.c.
2277 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Fixed the private message sending in the Irssi SILC client,
2280 added local command KEY to the Irssi SILC client.
2282 Added key management and key agreement message formats to the
2283 irssi/src/fe-common/silc/module-formats.[ch].
2285 Added USERS (alias WHO) printing, server/router operator
2286 indication and LIST command printing to the module formats.
2288 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Fixed channel joining notify handling, cumode notify handling
2291 from Irssi SILC client.
2293 * Added SILC specific module-formats to the Irssi SILC client so
2294 that SILC specific message hilighting, colors etc is possible.
2295 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2297 Added channel mode, channel user mode, actions, notices,
2298 whois and whowas printing to the the module-formats.c.
2300 * Fixed a bug in channel deletion in the server. The channel
2301 is not left to the cache even if the channel founder auth mode
2302 is set when there are no users anymore on the channel. Affected
2303 file silcd/server.c.
2305 * The silc_net_localhost now resolves the entire hostname including
2306 the domain name. Affected file lib/silcutil/silcnet.c.
2308 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Changed the ask_passphrase client operation to be ascynchronous.
2311 It has now a completion callback and a context that the
2312 application must call after it has got the passphrase from
2313 the user. Affected files lib/silcclient/silcapi.h,
2314 lib/silcclient/protocol.c, lib/silcclient/command.c and
2317 Added SilcAskPassphrase callback that the application calls
2318 to deliver the passphrase to the library.
2320 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2321 The public key verification and especially a certificate
2322 verification is asynchronous procedure.
2324 Added new SILC_SKE_STATUS_PENDING status to indicate the
2325 request is pending and a callback will be called to finalize
2328 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2329 indicate that remote end did not send its public key (or
2330 certificate), even though we require it. Added check for this
2331 condition in the SKE. This was a security bug, now fixed.
2333 Defined new SilcSKEVerifyCbCompletion callback that is called
2334 when the verification process is completed.
2336 The affected files lib/silcske/silcske_status.h and
2337 lib/silcske/silcske.[ch].
2339 * Changed the verify_public_key client operation to be async
2340 as well. Defined SilcVerifyPublicKey callback that is used to
2341 indicate the success of the public key verification process.
2343 Changed the server and client to use the new async client
2346 * Changed the Irssi SILC client's internal scheduler to be called
2347 twice as many times as it used to be. As a result the client
2348 should be a bit faster now. Affected file is
2349 irssi/src/silc/core/silc-core.c.
2351 * Added support to Irssi SILC client of asynchronous public key
2352 verification and passphrase inquiry. Affected file is
2353 irssi/src/silc/core/silc-core.c.
2355 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2357 * Do not say "You have left channel %s" in client library.
2358 Moved it to the application. Affected files are
2359 lib/silcclient/command.c and silc/client_ops.c.
2361 * Fixed silc_client_get_clients. Command context was not
2362 duplicated and was freed memory in the callback. Affected
2363 file lib/silcclient/idlist.c.
2365 * Do not say "you are now talking..." on JOIN command in the
2366 client library. The appliation must handle it.
2368 * Do not say ".. changed topic to" in command reply in the
2369 client libary. The application must handle it.
2371 * Fixed TOPIC command sending in the client library.
2373 * Fixed a memory leak in silc_client_command_free in the file
2374 lib/silcclient/command.c.
2376 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Imported a modified version of Irssi client to the source tree.
2379 The Irssi will be used to create a new client called
2380 Irssi SILC. Imported to irssi/.
2382 Added silc_core_init_finish function to the Irssi. Affected
2383 file irssi/configure.in.
2385 A lot changes in the Makefile.ams around the irssi tree.
2387 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Do not rehash if the new size is same as the old size of the
2390 hash table, in the silc_hash_table_rehash*. The affected file
2391 lib/silcutil/silchashtable.c.
2393 * Replaced hash_table_del_by_context calls from the server
2394 (when channel->user_list and client->channels) to the
2395 hash_table_del as it is sufficient and faster.
2397 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Added silc_hash_table_list, silc_hash_table_get and the
2400 SilcHashTableList structure to provide an alternative way to
2401 traverse the hash table. The affected files are
2402 lib/silcutil/silchashtable.[ch].
2404 * Changed the server's idlist routines to use the hash table
2405 routines to optimize the code.
2407 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Replaced the client entry's `channel' list and channel entry's
2410 `user_list' list to hash tables for optimized lookup. Changed
2411 the code to use the hash table interface around the code.
2412 Affected file lib/silcd/idlist.[ch].
2414 * Added `auto_rehash' boolean argument to the function
2415 silc_hash_table_alloc to indicate whether the hash table should
2416 auto-rehash when it thinks is appropriate time. It will
2417 increase the hash table size if the there is twice as much
2418 entries in the table than the size of the table, and will
2419 decrease the size if there are twice as less entries than
2420 the size of the table.
2422 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2426 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * silc_idcache_purge_by_context deletes the entry now by context
2429 as it is supposed to do. Affected file lib/silccore/idcache.c.
2431 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2432 client is not anymore valid (WHOWAS givens the info) and not
2433 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2435 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Removed the `data' and `data_len' arguments from the ID Cache
2438 interfaces and added `name' argument. ID Cache does not handle
2439 anymore the binary data only a names associated with given ID.
2441 * When hashing a Client ID with silc_hash_id the entire ID is
2442 not hashed anymore, instead only the hash of the Client ID is
2443 hashed. This way we can access the Client ID from the cache
2444 with Client ID but with the hash of the ID (which is a hash of
2445 the nickname) as well without any difference in performance.
2447 Added also silc_idcache_find_by_id_one_ext to do one on one
2448 searching when we have the actual ID. Added also function
2449 silc_hash_client_id_compare. The affected files are
2450 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2452 * When hashing the name associated with a ID it is always done
2453 in lowercase. This way we can access the cache without worrying
2454 about case-sensitivity, even though, for example nicknames are
2457 * Fixed a bug in server with channel message sending. It put
2458 wrong ID type as destination ID. The affected file
2459 silcd/packet_send.c.
2461 * silc_idcache_del_by_context now deletes from all hash tables
2462 by context. Affected file lib/silccore/idcache.c.
2464 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Changed the client library to use the new ID Cache interface.
2467 Changes around the source tree.
2469 * Added silc_hash_table_rehash_ext to rehash with specific
2470 hash function. Affected file lib/silcutil/silchashtable.[ch].
2472 * Added silc_hash_string_compare to compare two strings in the
2473 hash table. Affected file lib/silcutil/silcutil.[ch].
2475 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Added new function silc_idcache_del_by_context into the
2478 lib/silccore/idcache.[ch].
2480 * Changed the server's ID list routines to use the new ID Cache
2481 interface. Changes around the source tree.
2483 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Added silc_hash_table_del[_by_context]_ext functions in to the
2486 lib/silcutil/silchashtable.[ch].
2488 Removed silc_hash_table_find_all* routines and added new
2489 silc_hash_table_find_foreach to replace them.
2491 Added silc_hash_table_replace_ext function as extended
2492 replacing function. Separated the simple hash table interface
2493 from the extended hash table interface in the file
2494 lib/silcutil/silchashtable.h.
2496 * Fixed minor bugs and changed it to use some of the new
2497 hash table functions in lib/silccore/idcache.c
2499 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Added new function silc_hash_table_find_all to return all keys
2502 in the hash table by the specified key. As the hash table is
2503 collision resistant it also makes it possible to have several
2504 duplicate keys in the hash table. This function may be used to
2505 find all of the keys from the hash.
2507 Added user_context arguments to the SilcHashFunction,
2508 SilcHashCompare and SilcHashDestructor to deliver user specified
2511 Added new fuctions silc_hash_table_find[_all]_ext to do
2512 extended lookup with specified hash and compare functions and
2513 specified user contexts.
2515 Added new function silc_hash_table_add_ext to add the key
2516 with specified hash function and user context.
2518 Added new function silc_hash_table_foreach to traverse all
2519 entrys in the hash table. Added SilcHashForeach callback
2522 Added new function silc_hash_table_del_by_context to delete
2523 the entry only if the context associated with the key matches.
2525 Affected files are lib/silcutil/silchashtable.[ch].
2527 * Removed silc_hash_[server/client/channel]_id and added just
2528 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2529 silc_hash_id_compare to compare two ID's using as the hash table
2530 comparison function. Added also silc_hash_data to hash
2531 binary data and silc_hash_data_compare to compare it.
2533 * Removed silc_idlist_find_client_by_hash as it is not needed
2534 anymore. Affected file silcd/idlist.[ch].
2536 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2537 to use internally the SilcHashTable. The new ID Cache is a lot
2538 faster than the old one. Some of the ID Cache interface was also
2539 rewritten and obsolete and stupid functions were removed.
2541 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Added entry_count field to the SilcHashTable to keep the number
2544 of the entries in the table. Implemented the function
2545 silc_hash_table_rehash. Added new function
2546 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2548 Fixed a minor bug in silc_hash_table_free.
2550 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2551 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2552 into the lib/silcutil/silcutil.[ch].
2554 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Implemented a collision resistant hash table into the
2557 lib/silcutil/silchashtable[ch]. See the header and the source
2558 for the SilcHashTable API.
2560 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Merged dotconf version 1.0.2 into lib/dotconf.
2564 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2566 * Do not compile anything in lib/silcsim/* if the SIM support
2567 is not enabled. The tree should now compile without problems
2570 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Compiled the SILC under cygwin. Compiled and tested briefly
2573 without problems. More tests needed. The SIMs didn't compile
2576 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2578 * Fixed possible crash in silc_get_username in the
2579 lib/silcutil/silcutil.c.
2581 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Fixed a va_arg in silc/client_ops.c.
2585 * Oops, RC5 routines were named AES and caused some problems
2586 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2588 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Added new SilcIDIP structure into the lib/silccore/id.h and
2591 replaced the old `ip' fields from all SILC ID's to that type.
2592 This is a step towards IPv6 support.
2594 The silc_id_get_len takes now the ID as an extra argument.
2595 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2596 both IPv4 and IPv6 based ID's.
2598 The affected files are lib/silccore/id.[ch] and other files
2599 around the tree using these routines.
2601 * Removed the ID length arguments in server from various
2602 silc_server_send_notify_* routines -> they are not needed
2605 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Fixed memory leak in silc_encode_pem_file in the file
2608 lib/silcutil/silcutil.c.
2610 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Check minor version as well in the SKE. Affected files are
2613 silcd/protocol.c and lib/silcclient/protocol.c.
2615 * Added --identifier option to the server so that an identifier
2616 can be when creating the public key for the server. Affected
2617 file is silcd/silcd.c.
2619 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2620 lib/silccrypt/silcpkcs.c.
2622 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Register default ciphers and stuff when using -C option with
2625 the server. Affected file sildc/silcd.c.
2627 * Put back the servers public key filename format, it is better
2628 than the new one. For now, the client keys are saved with the
2629 new filename format. The affected file silc/client_ops.c.
2631 * Implemented the Cipher API for the rest of the ciphers that
2632 did not implement it or implemented it the wrong way.
2634 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Register default ciphers and stuff when using the -S option
2637 in the client. Affected file silc/silc.c. Same also when
2638 creating new key pair with -C option.
2640 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2642 * Fixed the silc_verify_public_key client operation function to
2643 save the public keys differently. The fingerprint is now
2644 used as filename and not the hostname. This way also the
2645 client keys are saved uniquely and not with hostnames. The
2646 affected file is silc/client_ops.c.
2648 * Trimmed the silc_hash_fingerprint function to remove extra
2649 whitespaces from the end of the fingerprint. The affected
2650 file is lib/silccrypt/silchash.c.
2654 * Added silc_cipher_register_default function to register all
2655 default ciphers. It can be used when configuration files
2656 does not exist and the application does not want any specific
2657 ciphers in any specific order.
2659 The SilcDList is now used as silc_cipher_list dynamically
2660 allocated cipher list. Removed the static list all together
2661 and now all ciphers must be allocated to the dynamic list.
2662 The silc_cipher_alloc routine was changed to check only the
2665 All silc_cipher_* routines that used to return int returns
2668 The affected files lib/silccrypt/silccrypt.[ch].
2670 * The same thing was done to silc_hash_* as for silc_cipher_*
2671 routines. Affected files lib/silccrypt/silchash.[ch].
2673 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2674 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2675 Added also silc_pkcs_[un]register[_default] functions.
2676 Removed the data_context from the PKCS API.
2678 * Added silc_hmac_register_default function to register default
2679 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2680 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2681 to unregister all hmacs at once.
2683 * Register the default ciphers, hash functions, PKCSs and HMACs
2684 if client's configuration file does not exist. The affected
2687 * The client did not load the hash functions from the SIM
2688 modules at all. Added support for this. Affected file is
2689 silc/clientconfig.c.
2691 * When decoding public key with silc_pkcs_public_key_decode, check
2692 the supported algorithm only if PKCS are registered. Affected
2693 file lib/silccrypt/silcpkcs.c. The same was done with the
2694 silc_pkcs_private_key_decode.
2696 * Fixed the SILC List routines to keep the list always in order.
2697 It used to change the list's order when traversing the list but
2698 not it preserves the order. Affected file lib/trq/silclist.h.
2700 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added the client library to use the SilcSocketConnection's
2703 reference counter (by silc_socket_dup) to prevent the bug that
2704 the socket object may be freed underneath async operation.
2706 * The name resolv library checking fixes in the configure.in.pre.
2709 * Created new version of the protocol drafts for future
2710 development. The -03 drafts are the ones that will be changed
2711 in the trunk now and the -02 will remain as they are.
2713 * Send list of CUMODE notifys to the router when announcing
2714 the channel users to the router. Affected file silcd/server.c.
2715 If the router receiving channel founder CUMODE for a channel
2716 that already has channel founder it will send CUMODE notify
2717 to the sender to remove the channel founder rights from the
2718 announced client. Affected file silcd/packet_receive.c.
2720 * The CUMODE notify may now use Server ID as well as the entity
2721 who changes the mode. Updated protocool specs.
2723 * Updated INSTALL and README files.
2725 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * New web pages in the http://silc.pspt.fi. The pages was
2732 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Implemented the [DenyConnectin] config section in the server.
2735 Added silc_server_config_denied_conn to check whether incoming
2736 connection is denied. Affected file silcd/serverconfig.[ch].
2738 * Do not check the ports when checking the incoming configuration
2739 data if the port is 0, meaning any. Affected file is
2740 silcd/serverconfig.c.
2742 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Fixed buffer overflow in silc_string_compare in the file
2745 lib/silcutil/silcutil.c.
2747 * Fixed double free in silc_server_command_leave in the file
2750 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Fixed the version checking in the server. Affected file is
2755 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Fixed the configuration data fetching when accepting new
2758 connections in the server. Affected file silcd/server.c.
2760 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Added `sender_entry' argument to the function
2763 silc_server_packet_relay_to_channel so that we can check
2764 whether some destination actually belongs to the same route
2765 the sender belongs (ie, we must not resend the packet to the
2766 sender). Affected file silcd/packet_send.[ch].
2768 * Added `servername' field to the SilcClientEntry in the server
2769 to hold the name of the server where client is from. Affected
2770 file is silcd/idlist.h.
2772 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Moved the channel message encrypting in the router betwen
2775 router connections from silc_server_channel_message to the
2776 silc_server_packet_relay_to_channel since we want to check
2777 whether we have anybody channel before encrypting anything.
2778 Affected files silcd/packet_[receive/send].c.
2780 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Fixed the [AdminConnection] server config section to support
2783 multiple entries. Affected file silcd/serverconfig.c.
2785 * Added support into the server to check the validity of the
2786 incoming connection before executing any KE or authentication
2789 * The connection configuration is now saved to the KE and
2790 connection auth protocol contexts and not fetched anymore in
2791 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2793 * The local hosts listenning address and port is also resolved
2794 now when starting the server. We want to have the socket object
2795 to include the real address and port for the listener. Added
2796 new function silc_net_check_local_by_sock into the files
2797 lib/silcutil/silcnet.[ch].
2799 * Fixed a broadcast bug in server -> do not broadcast if we
2802 * Fixed a routing bug. Do not route broadcast packets ever.
2803 Broadcast packets must be processed always and not routed since
2804 they may be destined to some other host than yourself and thus
2805 would get routed without no good reason. Affected file is
2808 * Added function silc_server_config_is_primary_route to check
2809 whether primary router connection has been configured (a router
2810 configuration that we are initiating). If there is not, we
2811 will assume that there is only two routers in the SILC network
2812 and we will use the incoming router connection as our primary
2813 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2815 * Changed the order of the broadcasting. Broadcast _after_ the
2816 packet has been processed not before. Affected file is
2819 * Fixed a [ClientConnection] parsing bug. The port was never
2820 parsed correctly thus resulting to port 0. Affected file
2821 silcd/serverconfig.c.
2823 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2824 argument and did not set the broadcast packet flag. Affected
2825 file silcd/packet_send.c. Fixed same bug in the function
2826 silc_server_send_notify as well.
2828 * If we receive NEW_ID packet for our own ID in the server, ignore
2831 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Removed the nickname from the Private Message Payload.
2836 Updated the code and the protocol specs.
2838 * Updated protocol specs for submitting to the IETF.
2840 * Tweaked the Random Number Generator a bit. Affected file
2841 lib/silccrypt/silcrng.c. Exported a new function
2842 silc_rng_[global]_add_noise which can be used to add more
2845 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Do not parse packets with different timeout when protocol
2848 is active -> may cause problem with rekey. Affected file
2851 * When server receives signoff notify it must not create
2852 new channel key if the client is on any channels since the
2853 sender of the signoff notify will create it.
2855 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Added printing of error messages during SKE protocol from the
2858 failure packet sent by server during SKE. Affected file
2861 * Removed the client's failure_callback handling with timeout
2862 and handle it immediately when received.
2864 * The SKE library returned wrong type in SUCCESS and FAILURE
2865 packets. They must be 32 bit MSB not 16 bit MSB.
2867 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Ok, rewrote the logic of the re-key and now it seems to work.
2870 I tested it on high traffic with frequent re-keys without
2871 problems. Added hmac_receive (and renamed hmac to hmac_send)
2872 in SilcClientConnection in lib/silcclient/client.h and
2873 in SilcIDListData in silcd/idlist.h. Also, removed the
2874 SilcPacketParserContext's cipher and hmac fields as they are
2875 not needed anymore and actually caused some problems when
2876 the ciphers and hmac's changed underneath the packet parser.
2878 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * If re-key protocol is active then process the incoming packets
2881 synchronously since we must assure that icoming packets encrypted
2882 with the old key is processed before the new keys is set to
2883 use. This is true other packets than for REKEY packets.
2884 Affected file silcd/server.c. The same was done to client library
2885 as well, affected file lib/silcclient/client.c.
2887 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Fixed bug in client and server to accept the force send if
2890 the packet is send from silc_[server/client]_packet_process
2891 function. Otherwise the packets are never delivered, oops.
2893 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Disable force sending of packets when REKEY protocol is active.
2896 We must assure that no packet is sent directly when rekey is
2897 performed. All packets must be sent through packet queue.
2898 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2899 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2900 function is silc_[server/client]_packet_send_real to check
2903 * Replaced the SIM paths from example config files to
2904 /usr/local/modules. Also, make install creates now
2905 /usr/local/silc/logs directory to hold all the SILC server
2908 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Made the configure.in.pre work on Solaris. Patch by salo.
2912 * Made all ciphers compatible with non-x86 machines. Defined
2913 CBC mode macros into lib/silccrypt/ciphers_def.h.
2915 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Fixed the make install.
2919 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * When MAC computation fails the silc_packet_decrypt returned 0
2922 even though it was supposed to return -1. Fixed this. The
2923 affected file is lib/silccore/silcpacket.c.
2925 * Do not replace the config files in /etc/silc (in make install)
2926 if they already exist. Affected file ./Makefile.am.
2928 * Do not send re-key packets immediately but through packet queue.
2929 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2931 * Changed silc_net_check_host_by_sock to return FALSE if the
2932 IP/DNS could not be resolved. Though, it returns the IP address
2933 now even if it could not resolve it (but returns also FALSE).
2934 Affected file lib/silcutil/silcnet.[ch].
2936 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Added silc_pkcs_decode_identifier to decode the public key's
2939 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2940 Added also silc_pkcs_free_identifier. Added also new context
2941 SilcPublicKeyIdentifier.
2943 * Added -S option to the silc client. It is used to dump the
2944 contents of the specified public key file.
2946 * Changed the PKCS api to return the public key length when
2947 setting the public key.
2949 * Fixed a fatal bug in the public and private key file loading.
2950 Affected file lib/silccrypt/silcpkcs.c.
2952 * Execute the packet parsing for client with zero (0) timeout
2953 if the protocol is active. Affected file silcd/server.c.
2955 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Made the key generation options to the silcd program. Added
2958 -C option, equivalent to client's option.
2960 * Added new [ServerKeys] config section to the server. It
2961 configures the server's public and private key.
2963 * Defined generic Public Key Payload into the protocol
2964 specification to send specific type of public keys and
2967 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2968 public key or certificate.
2970 * Implemented the GETKEY command to the server and to the
2971 client library and on user interface.
2973 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Made preliminary `make install' work.
2977 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Added SilcServerRekey context into silcd/idlist.h.
2981 * Added the PFS support as defined in the specification to the
2982 SKE protocol. Affected files lib/silcske/*.c.
2984 * Added `ske_group' field to the SilcServerRekey context to hold
2985 the number of the SKE group that is used with PFS in re-key.
2986 Affected file silcd/idlist.h.
2988 * Added PFS re-key support to the server. Affected file is
2991 * Added silc_protocol_cancel to cancel execution of the next
2992 state of the protocol. Affected file is
2993 lib/silccore/silcprotocol.[ch].
2995 * Added the re-key support with and without PFS to the client
2996 library. Re-key is performed once in an hour, by default.
2998 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2999 Added silc_client_rekey_callback and silc_client_rekey_final.
3000 Affected files are lib/silcclient/protocol.[ch] and
3001 lib/silcclient/client.[ch].
3003 * Removed the `hmac_key' and `hmac_key_len' fields from the
3004 SilcClientConnection structure; not needed. Affected file is
3005 lib/silcclient/client.h.
3009 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Do not ask whether user wants to use the negotiated private key
3012 for private messages, just use it. Affected file is
3013 silc/local_command.c.
3015 * Added `send_enc_key' and `enc_key_len' fields to the
3016 SilcIDListData structure since they are needed in the re-key
3017 phase. Affected file is silcd/idlist.[ch].
3019 * Implemented the simple re-key protocol into the server.
3020 Affected files silcd/server.c and silcd/protocol.[ch]. The
3021 re-key will be performed once in an hour, by default.
3023 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3024 Added silc_server_rekey, silc_server_rekey_callback and
3025 silc_server_rekey_final.
3027 * Removed Tunneled flag from the protocol. Updated the code
3028 and the specifications.
3030 * Adde `pfs' field to the SilcIDListData to indicate whether
3031 the PFS is to be performed in the re-key. Affected file is
3034 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3037 int64 of at least the xintXX size. If void * is less that 4
3038 bytes uint32 * will be used. Defined bool as boolean.
3040 * Changed _ALL_ unsigned long and unsigned int to uint32,
3041 unsgined short to uint16 in the source tree.
3043 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3044 not handle clients that has entry->data.registered == FALSE.
3045 They are not in the network anymore. Affected file is
3048 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Implemented the sending of the SERVER_SIGNOFF notify in the
3051 server. Affected file is silcd/server.c.
3053 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3054 Added also silc_notify_payload_encode_args into the
3055 lib/silccore/silcnotify.[ch].
3057 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3058 Affected file silcd/packet_receive.c.
3060 * Implemented the SERVER_SIGNOFF notify handling in the client
3061 library. Affected file lib/silcclient/client_notify.c. Also,
3062 implemnted the printing of the SERVER_SIGNOFF info to the
3063 application. Affected file silc/client_ops.c.
3065 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3066 if the deleting was successful. Affected file silcd/idlist.[ch].
3068 * Added support for public key authentication in the connection
3069 authentication protocol in the client library. Affected file
3070 lib/silcclient/protocol.c.
3072 * Changed the server's silc_idlist_get_clients_by_* interface
3073 to support already allocated array so that new entries may be
3074 added to pre-allocated array. Affected file silcd/idlist.[ch].
3075 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3076 and command replies.
3078 * All command reply functions in the server now calls the
3079 pending command callback even if error occured. This way the
3080 error will be delivered to the client as well. Affected files
3081 silcd/command.c and silcd/command_reply.c.
3083 * Fixed INFO command to return local server's info if no server
3084 was provided. Affected file lib/silcclient/command.c.
3086 * Removed RESTART command for good. Updated the code and the
3089 * Rewrote parts of the task system. It is a bit simpler now.
3090 Removed unsued task priorities. The affected files are
3091 lib/silcutil/silctask.[ch].
3093 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * Moved the USERS printing from the library to the application.
3096 Affected files lib/silcclient/command.c and silc/client_ops.c.
3098 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Added channel key re-key support. The re-key is perfomed
3103 only by the router and is done once in an hour. Added `rekey'
3104 field to the SilcChannelEntry in the server. Affected files
3105 silcd/server.c and silcd/idlist.h.
3107 * Added silc_task_unregister_by_context into the file
3108 lib/silcutil/silctask.[ch].
3110 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3112 * Added SILC_UMODE_GONE mode to indicate when the client is not
3113 present in the SILC network. Added also support to the local
3114 command AWAY that will set this mode. Added support of showing
3115 "xxx is gone" in WHOIS command. The USERS command shows the
3116 gone status as well.
3118 * Fixed setting server and router operator privileges in the
3119 server's UMODE command. Affected file silcd/command.c.
3121 * Merged the SKE KE1 and KE2 payloads into one payload. The
3122 new KE payload is equivalent to the old KE2 payload.
3124 Cleaned up the SKE Start Payload parsing. It now uses the
3125 simple buffer unformatting to do the parsing. A lot faster
3128 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3129 to the SKE that is used to indicate whether both of the SKE
3130 parties should perform authentication. By default only the
3131 responder performs authentication. By setting this flag also
3132 the initiator must do authentication. By default it is unset
3133 since in normal SKE case, client to server connection, only
3134 the responder should do authentication. When doing SKE between
3135 two clients both should perform authentication. Updated the
3136 code and the protocol specs.
3138 * A little fix to IDENTIFY command in the server. Search the
3139 client first by hash not nickname. Affected file is
3142 * Fixed the silc_client_close_connection to support closing
3143 the client to client connections wihtout deleting too much
3144 data. Affected file lib/silcclient/client.c.
3146 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3147 are received if protocol used to be active but is not anymore
3148 the application would crash due to NULL pointer dereference.
3149 Affected files silcd/server.c and lib/silcclient/client.c.
3151 * Added `hash' field to the SilcClientConnection to include
3152 the hash function negotiated in the SKE protocol.
3154 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3155 to set the channel founder authentication data. A client can
3156 claim the founder rights later by providing the authentication
3157 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3158 This way the channel founder can regain the channel founder
3159 privileges even it is left the channel. This works only on
3160 local server and the client must be connected to the same
3161 server to be able to regain the founder rights. Updated the
3162 protocol specs accordingly.
3164 Added support to the CMODE command in the client to set the
3165 founder auth data. Read the README to see how to set it.
3167 Added support to the CUMODE command to claim the founder
3168 rights. Read the README to see how to do it.
3170 Added support for the founder authentication to the Channel
3171 Entry in the server. Affected file silcd/idlist.h.
3173 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3174 server's CMODE command. Affected file silcd/command.c.
3176 * Added the following new functions into lib/silccore/silcauth.[ch]:
3177 silc_auth_get_method and silc_auth_get_data.
3179 * The server now saves the remote hosts public key to the
3180 SilcIDListData pointer. Affected file silcd/protocol.c.
3182 * The normal server now does not remove the channel entry from
3183 the cache if the founder authentication data is set. It used
3184 to remove it if the founder was the last one on the channel on
3185 the server and left the channel. The auth data is saved and
3186 if the channel is re-joined later the old entry is used with
3187 the old auth data. Affected files silcd/command_reply.c and
3190 * Removed the `pkcs' field from the SilcIDListData structure
3191 in the server; it is not used. Affected file silcd/idlist.h.
3193 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Fixed packet processing on slow links. Partial packets were
3196 never re-processed because the incoming data buffer was cleared
3197 by the application. Application must not directly clear the
3198 sock->inbuf, the packet processing routines handle it. Fixed
3199 this in client library and in server.
3201 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3203 * Fixed the WHOIS and IDENTIFY send reply function to really
3204 check whether to send list or just one entry. Affected file
3207 * Cleaned up the LEAVE command's channel key distribution. The
3208 affected file silcd/command.c.
3210 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3211 can enforce the channel mode as well. In that case the ID
3212 includes the ID of the server. The code now enforces the
3213 mode change if the router have different mode than the server.
3215 * The notify client operation with CMODE_CHANGE notify can now
3216 return NULL client_entry pointer if the CMODE was not changed
3217 by client. Application must check for this.
3219 * Added <Server ID> argument to INFO command to support server
3220 info fetching by Server ID.
3222 * Added silc_server_announce_get_channel_users to get assembled
3223 packets of channel users of the specified channel. Affected
3224 file silcd/server.[ch].
3226 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3227 was freed underneath the ID Cache.
3229 * Re-announce clients when the server received CHANNEL_CHANGE
3230 notify from the router. Affected file silcd/packet_send.c.
3232 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3235 crashed since it did not handle the fact that there is no cipher
3236 called "3" and didn't check the error condition. Now fixed.
3238 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3239 flag. It can be used to send message requests.
3241 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * Implemented the RESTART command in the client.
3245 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3246 notice type messages. Added notice printing to the user
3249 * The channel keys are not re-generated if the channel's mode
3250 is PRIVKEY, ie private key on the channel exists. Affected
3251 files silcd/server.c and silcd/command.c.
3253 * Fixed a little bug in channel message delivery when channel
3254 private keys are set in the server. Affected file is
3255 silcd/packet_send.c.
3257 * Changed the setting on channel->on_channel = TRUE from the
3258 silc_client_save_channel_key to the JOIN command reply. The
3259 key payload is not received if the private channel key is set.
3260 Affected file lib/silcclient/command_reply.c and the
3261 lib/silcclient/client_channel.c.
3263 * When the CMODE_CHANGE notify is sent and the channel private
3264 key mode is removed the channel key must be re-generated in
3265 other cells as well. Added this support for the router in the
3266 silcd/packet_receive.c.
3268 * Added new local command NOTICE to send notice message on
3269 channel. Affected file silc/local_command.[ch].
3271 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Added new local command ME to the client. It is used to send
3274 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3275 some action. Affected file silc/local_command.[ch].
3277 * Changed channel_message and private_message client operations
3278 to deliver the message flags to the application. Added also
3279 the `flags' arguments to the silc_client_send_channel_message
3280 and silc_client_send_private_message functions. Affected file
3283 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Redefined the Private Message Payload to support private message
3286 keys and to support the new private message flags. Updated
3287 the protocol specs. Flags makes it possible to have for example
3288 CTCP style messages.
3290 * Added new type SilcPrivateMessagePayload and defined an API
3291 for it in the lib/silcclient/silcprivate.[ch].
3293 * Tested private message private keys successfully. Tested the
3294 private message key set, unset and list commands with the new
3297 * Redefined the Channel Message Payload to include the channel
3298 message flags (equal with private message flags) to support
3299 for example CTCP style messages.
3301 * Defined some of the message (for channel and private message)
3302 flags. Updated the protocol specs and added the flags to the
3303 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3305 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Added SilcKeyAgreementStatus type to the key agreement routines
3308 to indicate the current status and error if one occured.
3309 The status types are defined in the lib/silcclient/silcapi.h.
3311 * Added new local command KEY that is used to set and unset private
3312 keys for channels, set and unset private keys for private messages
3313 with remote clients and to send key agreement requests and
3314 negotiate the key agreement protocol with remote client. The
3315 key agreement is supported only to negotiate private message keys,
3316 it currently cannot be used to negotiate private keys for channels,
3317 as it is not convenient for that purpose.
3319 * Fixed a minor pending callback setting bug in the function
3320 silc_client_get_client_by_id_resolve, now the function works.
3321 Affected file lib/silcclient/idlist.c.
3323 * Added function silc_net_get_local_port to get local bound
3324 port by socket. Added to lib/silcutil/silcnet.[ch].
3326 * Added `sockets' and `sockets_count' fields to the SilcClient
3327 object. They hold the sockets of the listenning sockets in
3328 the client. Listenning sockets may be for example the key
3329 agreement server. Affected file lib/silcclient/client.[ch].
3330 Added functions the silc_client_add_socket and the
3331 silc_client_del_socket. They are exported to the application
3334 * Added ~./silc/clientkeys to support other client's public keys.
3336 * Renamed verify_server_key client operation to verify_public_key
3337 and added one argument to indicate the type of the connection
3338 (server, client etc.).
3340 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added silc_server_connection_auth_request to handle the
3343 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3344 silcd/packet_receive.[ch].
3346 * Added silc_server_send_connection_auth_request into the
3347 silcd/packet_send.c to send the connection auth request packet.
3349 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3352 * Fixed the public key authentication in responder side in the
3353 server. The `auth_data' pointer includes the SilcPublicKey
3354 not the path to the public key. Affected file silcd/protocol.c.
3356 * Implemented the public key authentication in the initiator side
3357 in the server. Affected file silcd/protocol.c.
3359 * Removed the [RedirectClient] config section from the server
3360 configuration. Is not needed and I don't want to implement it.
3362 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Cleaned up the CMODE command in the server. It now works
3365 correctly and supports all the modes defined in the protocol.
3366 Affected file is silcd/command.c.
3368 * Added `hmac_name' field to the SilcChannelEntry in the server
3369 to hold the default HMAC of the channel. It can be set when
3370 creating the channel (with JOIN command). Affected files
3373 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3374 type to indicate the change of the current cipher and hmac
3375 on the channel. Client can safely ignore the <cipher> argument
3376 (if it chooses to do so) since the CHANNEL_KEY packet will
3377 force the channel key change anyway. The <hmac> argument is
3378 important since the client is responsible of setting the new
3379 HMAC and the hmac key into use.
3381 * Fixed the CMODE command in the client library as well.
3383 * Tested CMODE command in router environment successfully.
3385 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Show the version of the remote client (or server) when connecting
3388 to the server. It is logged to the log file. Affected file
3389 is silcd/protocol.c.
3391 * Fixed the KILLED notify handling in the client library. The
3392 client must be removed from all channels when receiving the
3395 Also, do not remove the client entry when giving the KILL
3396 command but when the KILLED notify is received.
3398 * Removed silc_idlist_find_client_by_nickname from the server.
3399 Not needed anymore. Affected files silcd/idlist.[ch].
3401 * Implemented the CHANNEL_CHANGE notify type handling to the
3402 server. Affected file silcd/server.c.
3406 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3408 * Added silc_server_send_notify_invite to send the INVITE
3409 notify between routers.
3411 * Implemented the INVITE command correctly to the server.
3413 * Implemented the INVITE notify type handling in the server.
3415 * Implemented the INVITE command to the client library and on the
3418 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Added function silc_server_get_client_resolve to find the
3421 client entry by ID from all ID lists and then resolve it
3422 (using WHOIS) if it cannot be found. Affected file is
3425 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Implemented the BAN command to the client library.
3429 * The JOIN command in the server now checks the invite list
3432 * Changed the silc_command_reply_payload_encode_va and the
3433 silc_command_payload_encode_va to support that if argument is
3434 NULL it ignores and checks the next argument. Affected file
3435 lib/silccore/silccommand.c.
3437 * Added silc_server_send_notify_ban to send the BAN notify
3438 type between routers.
3440 * Chaned the silc_notify_payload_encode to support that if
3441 argument is NULL it ignores and checks the next argument.
3442 Affected file lib/silccore/silcnotify.c.
3444 * Tested ban lists in router environment successfully.
3446 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Implemented BAN command to the server, in silcd/command.[ch].
3450 * Removed the BAN and INVITE_LIST modes from the CMODE command
3453 * Added function silc_string_match to regex match two strings.
3454 Affected files lib/silcutil/silcutil.[ch].
3456 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Redefined parts of the SilcChannelEntry in the server to support
3459 the new ban and invite lists.
3461 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Redefined the INVITE command. The same command can be used to
3464 invite individuals to the channel but also to manage the invite
3465 list of the channel (to add to and remove from the invite list).
3466 Updated the protocol specs.
3468 * Added new command SILC_COMMAND_BAN that can be used to manage
3469 the ban list of the channel. Updated the protocol specs.
3471 * Removed the channel modes: the SILC_CMODE_BAN and the
3472 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3473 in the CMODE command. The equivalent features are now available
3474 using INVITE and BAN commands. Updated the protocol specs.
3476 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3477 in the network about change in the current ban list. The notify
3478 type is not used by the client.
3480 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3481 support the invite lists.
3483 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added new function silc_string_regexify that converts string
3486 including wildcard characters into regex string that can
3487 be used by the GNU regex library. Added into the file
3488 lib/silcutil/silcutil.[ch].
3490 Added silc_string_regex_combine to combine to regex strings
3491 into one so that they can be used as one regex string by
3492 the GNU regex library. Added into the file
3493 lib/silcutil/silcutil.[ch].
3495 Added silc_string_regex_match to match two strings. It returns
3496 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3498 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Imported GNU regex to the soruce tree into lib/contrib.
3501 Fixed some compiler warning from the regex.c.
3503 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Fixed MOTD command in the server to work in router environment.
3507 * Fixed the MOTD command in the client library to support
3508 the server argument in the command.
3510 * Added `nickname_len' argument to the silc_idlist_add_client
3511 in the server, as the `nickname' argument may be binary data
3514 * Added silc_idlist_get_channels to return all channels from
3517 * Implemented LIST command to the server. Affected file is
3520 * Implemented the LIST command to the client library and on the
3523 * Added [<user count>] argument to the LIST command reply.
3524 With private channels the user count is not shown.
3526 * Updated TODO and README.
3528 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * The client entry's data.registered must be TRUE even with
3531 global client entry on global client list. The data.registered
3532 is used to check whether the client is anymore in the network,
3533 for example with WHOWAS command so it must be valid.
3535 * Fixed the WHOWAS command in the server. It now actually works
3536 in router environment. Added function into silcd/command_reply.c
3537 silc_server_command_reply_whowas_save.
3539 * Added silc_idlist_purge function to the silcd/idlist.c
3540 to periodically purge the ID Cache.
3542 * Fixed INFO command in the server. It works now in router
3543 environment. Added <server name> argument to the INFO command
3544 reply. Updated the protocol specs.
3546 * Fixed minor bug in silc_idcache_purge to not purge if the
3547 expire value is zero.
3549 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3550 they were buggy because of the WHOWAS information.
3552 * Fixed local command MSG to handle the async resolving of
3553 the remote client properly. It used to fail the first MSG.
3554 Affected file silc/local_command.c.
3556 * Added `data_len' field to SilcIDCache context.
3558 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Update TODO. Todo in commands in the server.
3562 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3565 used by routers as broadcast packet to inform other routers
3566 about the changed user mode.
3568 Implemented the notify handling in the server. Affected file is
3569 silcd/packet_receive.c. Added the function
3570 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3572 * Added new generic Channel Payload and deprecated the New Channel
3573 Payload. The New Channel Payload is now the generic Channel
3576 * Added new argument `mode' to the silc_server_send_new_channel
3577 as it is required in the Channel Payload now.
3579 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3580 and created a new and real SilChannelPayload to represent the
3581 new generic Channel Payload. Implemented the encode/decode
3582 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3584 * Added silc_server_get_client_channel_list to return the list
3585 of channels the client has joined for WHOIS command reply.
3586 Affected file silcd/server.[ch].
3588 * Implemented the channel list sending in the WHOIS command reply
3589 in server and in the client.
3591 Implemented the channel list displaying on the user interface
3592 as well. Affected file silc/client_ops.c.
3594 * Added silc_channel_payload_parse_list to parse list of Channel
3595 Payloads. It returns SilcDList list of SilcChannelPayloads.
3596 Client for example can use this function to parse the list of
3597 channels it receives in the WHOIS command reply. The caller
3598 must free the list by calling silc_channel_payload_list_free.
3599 Affected files lib/silccore/silcchannel.[ch].
3601 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Added one new argument <user mode> to the WHOIS command reply
3604 to return the mode of the user in SILC. Updated the protocol
3607 Implemented it to the server and client.
3609 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Fixed the mode printing on the user interface on joining.
3612 Affected file silc/client_ops.c.
3614 * Implemented the UMODE command and user modes in general to the
3615 client library and to the user interface.
3617 * Implemented the UMODE command to the server.
3619 * The server now sends UNKNOWN_COMMAND error status if client sends
3620 unknown command. Affected file silcd/command.c.
3622 * All server commands now handle the command identifier the right
3623 way when sending the command reply to the client. The client can
3624 use to identify the command replies with the identifier.
3626 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Added silc_server_get_client_route to resolve the route to
3629 the client indicated by the client ID. Affected file is
3632 * Added silc_server_relay_packet as general function to relay
3633 packet to arbitrary destination. This deprecates functions
3634 like _send_private_message_key, _relay_notify etc. Affected
3635 file is silcd/packet_send.[ch].
3637 Removed silc_server_send_key_agreement,
3638 silc_server_send_private_message_key and
3639 silc_server_packet_relay_notify functions from the file
3640 silcd/packet_send.[ch].
3644 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3645 server. Affected file silcd/packet_receive.[ch].
3647 * Implemented the KILL command to the client. Implemented the
3648 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3649 Affected files lib/silcclient/command[_reply].c and
3650 lib/silcclient/client_notify.c. Implemented the KILL notify
3651 printing in the user inteface.
3653 * Fixed a lot silc_parse_nick memory leaks from the client
3654 library in the file lib/silcclient/command.c.
3656 * Changed the silc_server_send_notify_on_channels's `sender'
3657 argument from SilcSocketConnection to SilcClientEntry to
3658 check the sender as entry and not as connection object and not
3659 to send to the client provided as argument. The affected file
3660 is silcd/packet_send.[ch].
3662 * The notify packets that are destined directly to the client used
3663 to not to be processed by the server. Now changed that and the
3664 server processes all notify packets. After relaying the packet
3665 to the client the notify packet is processed in the server.
3667 * The silc_server_free_client_data now checks whether there is
3668 pending outgoing traffic for the client and purges the data to
3669 the network before removing the client entry.
3671 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3674 an client is killed from the SILC Network. Updated the protocol
3677 Added new function silc_server_send_notify_killed to the
3678 silcd/packet_send.[ch].
3680 * Added function silc_server_packet_relay_notify to relay notify
3681 packets that are destined directly to a client. In this case
3682 the server does not process the notify packets but merely relays
3683 it to the client. Affected file silcd/packet_send.[ch].
3685 Added also silc_server_packet_process_relay_notify to check
3686 whereto relay the notify. Affected file is
3687 silcd/packet_receive.[ch].
3689 * Implemented the KILL command to the server.
3693 * Added the backup schema desgined last fall to the protocol
3694 specs for everyone to see. The specification is in the
3695 *-spec-xx.txt draft and the packet type definitions for the
3696 backup routers is in *-pp-xx.txt draft. Thusly, added also
3697 new packet type SILC_PACKET_CELL_ROUTERS.
3699 * A big security problem in the implementation discovered. The
3700 signoff of an client did not cause new channel key generation
3701 which it of course should've done. The channel keys must be
3702 always re-generated when client leaves (or signoffs) the channel.
3703 The silc_server_remove_from_channels funtion now handles
3704 the channel key re-generation.
3706 * Added `sender' argument to the silc_server_send_notify_on_channels
3707 to not to send the client provided as argument. Affected file
3708 silcd/packet_send.[ch].
3710 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Implemented OPER and SILCOPER commands into the server and
3715 * Added silc_auth_verify and silc_auth_verify_data to verify
3716 the authentication directly from the authentication payload.
3717 It supports verifying both passphrase and public key based
3718 authentication. Affected file lib/silccore/silcauth.[ch].
3720 * Added `hash' field to the SilcIDListData structure. It is the
3721 hash negotiated in the SKE protocol. Affected file is
3724 * Slight redesigning of the SilcAuthPayload handling routines.
3725 Do not send SilcPKCS but SilcPublicKey as argument.
3727 * Implemented the public key authentication support to the
3728 serverconfig. The public key is loaded from the provided path
3729 and saved as authentication data to void * pointer. Thus,
3730 changed the unsigned char *auth_data to void *auth_data;
3732 * Fixed SHUTDOWN command to send the reply before the server
3733 is shutdown. :) Affected file silcd/command.c.
3735 * Fixed fatal bug in CONNECT command. The hostname was invalid
3736 memory and server crashed. Affected file silcd/command.c.
3738 * Fixed fatal bug in CLOSE command. The server_entry became
3739 invalid but was referenced later in the command. Affected file
3742 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Fixed fatal bug in failure packet handling. Server ignored
3745 the failure and thus crashed when it came.
3749 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3752 that the command may be executed only once in (about) 2 seconds.
3753 The old SILC_CF_LAG flag is same but allows command bursts up
3754 to five before limiting.
3756 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3757 server code. Various commands now includes the CF_LAG_STRICT
3758 flag to disallow any kind of miss-use of the command.
3760 * Fixed the silc_buffer_unformat to not to allocate any data
3761 if the length of the data is zero. It used to allocate the
3762 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3764 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Changed the format of AdminConnection configuration section
3767 in the server. Added username of the admin to the format.
3768 Affected files silcd/serverconfig.[ch].
3770 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3771 to return admin configuration data by host, username and/or
3774 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Implemented WHOWAS command to the server. Added the functions:
3778 silc_server_command_whowas_parse,
3779 silc_server_command_whowas_send_reply,
3780 silc_server_command_whowas_from_client and
3781 silc_server_command_whowas_from_server
3783 * Added <Client ID> argument to the WHOWAS command reply. Updated
3784 the protocol specs accordingly.
3786 * Implemented WHOWAS command and command_reply to the client
3789 Implemented the WHOWAS printing on the user interface.
3791 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Added new argument to the WHOWAS command reply, the real name.
3794 It is an optional argument. Updated the protocol specs.
3796 * Added SilcIDCacheDestructor callback that is registered when
3797 the SilcIDCache is allocated. The callback is called when
3798 an cache entry in the ID Cache expires, or is purged from the
3799 cache. Added into lib/silccore/idcache.[ch].
3801 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3802 to destruct the client entries when the cache entry expires.
3803 Other ID Cache's in server and in the client library ignores
3806 * If the ID Cache entry's `expire' field is zero then the entry
3807 never expires. Added boolean `expire' argument to the
3808 silc_idcache_add function in the lib/silccore/idcache.[ch].
3809 If it is TRUE the default expiry value is used.
3811 * Added silc_server_free_client_data_timeout that is registered
3812 when client disconnects. By default for 5 minutes we preserve
3813 the client entry for history - for WHOWAS command.
3815 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Added support to the server to enforce that commands are not
3818 executed more than once in 2 seconds. If server receives
3819 commands from client more frequently, timeout is registered
3820 to process the commands. Affected file silcd/command.c.
3821 Added new function silc_server_command_process_timeout.
3823 * Changed NICK_NOTIFY handling in client library to check that
3824 if the client's nickname was changed, so there is no need to
3825 resolve anything from the server.
3827 * Removed error printing from the WHOIS and IDENTIFY commands.
3828 If error occurs then it is ignored silently in the client library.
3829 The application, however, may map the received error to
3830 human readable error string. The application currently maps
3831 the NO_SUCH_NICKNAME error to string.
3833 * Made the command status message public to the application. Moved
3834 them from lib/silcclient/command_reply.c to
3835 lib/silcclient/command_reply.h. The application can map the
3836 received command status to the string with the
3837 silc_client_command_status_message function.
3839 * Added check to the server to check that client's ID is same
3840 as the Source ID in the packet the client sent. They must
3843 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Added dist-bzip hook to the Makefile.am to make bzip2
3846 compressed distributions.
3848 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Server now enforces the maximum length for the nickname and
3851 the channel as protocol specification dictates. 128 bytes for
3852 nickname and 256 bytes for channel name.
3854 * Moved the WHOIS printing to the application. The client libary
3855 does not print out the WHOIS information anymore, the application
3856 must do it. Renamed silc_client_command_reply_whois_print to
3857 the silc_client_command_reply_whois_save.
3859 The client's idle time is also sent to the application now, and
3860 the idle is shown on screen.
3862 * Added silc_client_command_reply_identify_save to save the
3863 received IDENTIFY entries.
3865 * Do not check for channel private keys in message sending and
3866 reception if the channel does not have the PRIVKEY mode set.
3867 Affected file lib/silclient/client_channel.c.
3869 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3872 just surfaced after chaning the JOIN procedure.
3874 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added silc_client_get_clients_by_list to get client entries
3877 from Client ID list, that is returned for example by JOIN
3878 and USERS command replies. The application should use this
3879 function for example when JOIN command reply is received to
3880 resolve the clients already on the channel (library does not
3881 do that anymore as USERS command reply is not used in the JOIN
3882 procedure anymore). Affected files lib/silcclient/silcapi.h and
3883 lib/silcclient/idlist.c.
3885 * JOIN command reply and USERS command reply returns now SilcBuffer
3886 pointers instead of unsigned char pointers when returning
3887 the client list and mode list.
3889 * Added <Client ID> argument to the JOIN command reply, mainly
3890 for the server to identify for which client the command was
3891 originally sent. Updated protocol specs accordingly.
3893 * Added SilcDlist private_key pointer to the SilcChannelEntry
3894 in the client to support the channel private keys. Affected
3895 file is lib/silcclient/idlist.h.
3897 * Added SilcChannelPrivateKey argument to the function
3898 silc_client_send_channel_message so that application can choose
3899 to use specific private ke if it wants to. If it is not provided,
3900 the normal channel key is used, unless private keys are set.
3901 In this case the first (key that was added first) is used
3902 as the encryption key.
3904 * Implemented the support for channel private key handling.
3905 Implemented the following functions:
3907 silc_client_add_channel_private_key,
3908 silc_client_del_channel_private_keys,
3909 silc_client_del_channel_private_key,
3910 silc_client_list_channel_private_keys and
3911 silc_client_free_channel_private_keys
3913 Affected file lib/silcclient/client_channel.c.
3915 * Added the support for the private keys in the channel message
3916 sending and encryption and in the message reception and
3917 decryption. Affected funtions are
3918 silc_client_send_channel_message and silc_client_channel_message.
3920 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Added SKE's key verify callback to the client library's
3923 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3925 * Removed the statement that server (or router) must send USERS
3926 command reply when joining to the channel so that the client
3927 knows who are on the channel. Instead, the client list and
3928 client's mode list is now sent in the JOIN command reply to the
3929 client who joined channel. This is better solution.
3931 * Added function silc_server_get_users_on_channel and function
3932 silc_server_save_users_on_channel to the silcd/server.[ch].
3934 * Removed function silc_server_command_send_users from the
3937 * Do not show topic on the client library anymore. The topic is
3938 sent in the command reply notify to the application and the
3939 application must show the topic now.
3941 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Added client searching by nickname hash into the IDENTIFY and
3944 WHOIS commands in the server as they were clearly missing from
3945 them. Affected file is silcd/command.c.
3947 * Fixed a bug in private message receiving in the client library.
3948 The remote ID was freed and it wasn't supposed, now it is
3951 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Minor fix to the channel payload; allocate the data area, as it
3954 needs to be of specific length.
3956 * If the key agreement port is zero then the operating
3957 system will define the bound port. Affected files are
3958 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3960 * Added new function silc_channel_payload_decrypt into the file
3961 lib/silccore/silcchannel.[ch].
3963 * Moved the channel message etc, check from silc_packet_decrypt
3964 to applications. The library calls now a generic
3965 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3966 when the packet is either normal or special. This was done to
3967 allow more wide range of checking that was not allowed when
3968 the code was in library. Now applications can do virtually any
3969 checks to the packet and return to the library the decision how
3970 the packet should be processed. Affected files are
3971 lib/silccore/silcpacket.[ch].
3973 Added silc_server_packet_decrypt_check to the server and
3974 silc_client_packet_decrypt_check to the client library.
3976 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3977 to send with specified source and destination information.
3979 * Channel message delivery between routers was broken after the
3980 channel key distribution was fixed earlier. The channel key
3981 was used be to distributed to other routers as well which is not
3982 allowed by the protocol. Now this is fixed and channel keys
3983 really are cell specific and the channel message delivery between
3984 routers comply with the protocol specification.
3986 * Fixed various commands in server to check also the global list
3987 for the channel entry and not just the local list. The affected
3988 file silcd/command.c.
3990 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Added assert()s to buffer formatting and unformatting routines
3993 to assert (if --enable-debug) when error occurs. Affected
3994 file: lib/silcutil/silcbuffmt.c.
3996 * Changed to auto-reconnect to check whether the remote host is
3997 router and register the re-connect timeout if it is. It used
3998 to check that whether we are normal server, but router must do
3999 auto-reconnect with another router as well. Affected file
4002 * Removed the [<key len>] option from CMODE command as the cipher
4003 name decides the key length, nowadays. See the defined ciphers
4004 from the protocol specification.
4006 * Added [<hmac>] option to the CMODE command to define the HMAC
4007 for the channel. Added SILC_CMODE_HMAC channel mode.
4009 * Added [<hmac>] option for the JOIN command so that user can
4010 select which HMAC is used to compute the MACs of the channel
4013 * Added Hmac field to the Channel Message Payload. The integrity
4014 of plaintext channel messages are now protected by computing
4015 MAC of the message and attaching the MAC to the payload. The
4016 MAC is encrypted. Now, it is clear that this causes some
4017 overhead to the size of the packet but rationale for this is that
4018 now the receiver can verify whether the channel message decrypted
4019 correctly and also when private keys are set for the channel the
4020 receiver can decrypt the packet with several keys and check from
4021 the MAC which key decrypted the message correctly.
4023 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4024 lib/silccrypt/silccipher.[ch].
4026 * Added silc_hash_len to return the digest length into the
4027 lib/silcrypt/silchash.[ch].
4029 * Rewrote parts of Silc Channel Payload interface in the
4030 lib/silccore/silcchannel.[ch]. The encode function now also
4031 encrypts the packet and parse function decrypts it.
4033 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Fixed a minor formatting bug in the SKE's key material processing.
4036 It actually might have processed the keys wrong way resulting
4039 * Redefined the mandatory HMAC algorithms and added new algorithms.
4040 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4041 and hmac-md5 truncated to 96 bits. The mandatory is now
4042 hmac-sha1-96. Rest are optional (including the one that used
4043 to be mandatory). Rationale for this is that the truncated HMAC
4044 length is sufficient from security point of view and can actually
4045 make the attack against the HMAC harder. Also, the truncated
4046 HMAC causes less overhead to the packets. See the RFC2104 for
4049 * Added new [hmac] configuration section. The SKE used to use
4050 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4051 is of course wrong. The official names that must be proposed in
4052 the SKE are the ones defined in the protocol specification
4053 (hmac-sha1-96 for example). The user can configure any hmac
4054 using any hash function configured in the [hash] section. At
4055 least, the mandatory must be configured.
4057 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4059 * Added HMAC list to the SKE proposal list. It has now both
4060 hash algorithm list and HMAC list. This makes the protocol
4061 incompatible with previous versions. The SKE now seems to work
4062 the way it is supposed to work, for the first time actually.
4064 * Defined plain Hash algorithms to the protocol specification.
4067 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Implemented support for key agreement packets into the server.
4070 Added functions silc_server_key_agreement and
4071 silc_server_send_key_agreement. Other than these functions,
4072 server has nothing to do with this packet.
4074 * Added support for private message key packets into the server.
4075 Added functions silc_server_private_message_key and
4076 silc_server_send_private_message_key.
4080 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4081 called in the protocol's final callback instead in the END
4082 protocol state. This makes a little more sense and in the same
4083 time in client we can use the same protocol routines for normal
4084 key exchange and to key agreement packet handling as well.
4086 * Added to both client's and server's KE protocol context the
4087 SilcSKEKeyMaterial pointer to save the key material. We will
4088 bring the key material to the protocol's final callback by doing
4089 this. The final callback must free the key material.
4091 * Added SKE's packet_send callback into client's KE protocol
4092 context so that the caller can choose what packet sending function
4093 is used. This way we can use different packet sending when
4094 doing normal SKE when doing key agreement packet handling (in
4095 the key agreement packet handling we do not want to encrypt
4098 * Implemented the responder side of the key agreement routines
4099 in the client. The client can now bind to specified port and
4100 accept incoming key negotiation. The key material is passed
4101 to the application after the protocol is over.
4103 * Implemented the processing of incoming Key Agreement packet
4104 in the client. Added function silc_client_key_agreement to
4107 * Implemented the intiator side of the key agreement routines
4108 in the client. The client can now initiate key agreement with
4109 another remote client. The key material is passed to the
4110 application after the protocol is over.
4112 * Created client_keyagr.c to include all the key agreement
4115 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4116 SILC_TASK_CALLBACK except that it is not static.
4118 * Created client_notify.c and moved the Notify packet handling
4119 from the client.[ch] into that file.
4121 * Created client_prvmsg.c and moved all private message and
4122 private message key routines from the client.[ch] into that file.
4124 * Create client_channel.c and moved all channel message and
4125 channel private key routines from the client.[ch] into that file.
4127 * Changed silc_client_get_client_by_id_resolve to resolve with
4128 WHOIS command instead of IDENTIFY command, in the file
4129 lib/silclient/idlist.c.
4131 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Implemented the SKE's responder side to the Client library.
4135 * When FAILURE is received to the protocol do not trust it
4136 blindly. Register a timeout to wait whether the remote closes
4137 the connection as it should do it, only after that process the
4138 actual failure. This was changed to both client and server.
4140 * Added client_internal.h to include some of the structures
4141 there instead of client.h in lib/silcclient/.
4143 * Added function silc_task_unregister_by_callback to unregister
4144 timeouts by the callback function.
4146 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Some "Incomplete WHOIS info" errors has been appearing on the
4149 log files. Took away the entry->userinfo check from WHOIS
4150 reply sending. The entry->userinfo is now " " if client did not
4151 provide one. I thought this was fixed earlier but something
4152 is wrong still. Let's see if the error still appears.
4154 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Fixed a minor bug in the login when the channel key is
4157 re-generated in the server. It used to generate the key in
4158 wrong order and thus caused problems in the channel traffic.
4160 * Fixed a minor bug in channel key distsribution after
4161 KICK command. The key was not sent to the router even though
4164 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Added silc_ske_process_key_material_data as generic routine
4167 to process any key material as the SILC protocol dictates. The
4168 function is used by the actual SKE library but can be used by
4169 applications as well. This relates to the private message keys
4170 and the channel private keys since they must be processed the
4171 same way the normal SILC session keys. The protocol dictates
4172 this. Affected files: lib/silcske/silcske.[ch].
4174 Added also silc_ske_free_key_material to free the
4175 SilcSKEKeyMaterial structure.
4177 * Defined silc_cipher_set_key function to set the key for
4178 cipher without using the object's method function. The affected
4179 files: lib/silccrypt/silccipher.[ch].
4181 * Implemented silc silc_client_add_private_message_key,
4182 silc_client_add_private_message_key_ske,
4183 silc_client_del_private_message_key,
4184 silc_client_list_private_message_keys and
4185 silc_client_free_private_message_keys functions in the
4188 Added functions silc_client_send_private_message_key to send
4189 the Private Message Key payload and silc_client_private_message_key
4190 to handle incoming Private Message Key payload.
4192 * Added Cipher field to the Private Message Key payload to set
4193 the cipher to be used. If ignored, the default cipher defined
4194 in the SILC protocol (aes-256-cbc) is used.
4196 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Removed lib/silcclient/ops.h file.
4200 Redefined parts of the SILC Client Library API. Created new
4201 file silcapi.h that deprecates the ops.h file and defines the
4202 published Client Library API. Defined also private message key
4203 API and channel private key API into the file.
4205 This is the file that the application must include from the
4206 SILC Client Library. Other files need not be included by
4207 the application anymore.
4209 * Added new key_agreement client operation callback and also
4210 defined the Key Agreement library API for the application.
4212 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4215 is used by clients to request key negotiation between another
4216 client in the SILC network. If the negotiation is started it
4217 is performed using the SKE protocol. The result of the
4218 negotiation, the secret key material, can be used for example
4219 as private message key.
4221 Implemented the Key Agreement payload into the files
4222 lib/silccore/silauth.[ch].
4224 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Redefined ciphers for the SILC protocol. Added some new ciphers
4227 and defined the key lengths for the algorithms. Changed the
4228 code accordingly. The default key length is now 256 bits.
4230 * Fixed SKE key distribution function silc_ske_process_key_material
4231 when the key length is more than 128 bits. The default key
4232 length in SILC is now 256 bits.
4234 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4235 to indicate unsupported algorithm.
4237 * Renamed rijndael.c to aes.c and all functions as well.
4239 * Fixed a long standing channel key setting bug in client library.
4240 Weird that it has never surfaced before.
4242 * Fixed bug in channel deletion. If the entire channel is removed
4243 then it must also delete the references of the channel entry
4244 from the client's channel list as the client's channel entry and
4245 the channel's client entry share same memory.
4247 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Implemented CONNECT and SHUTDOWN commands in the client.
4251 * Implemented CLOSE command to the client.
4253 * Added the function silc_idlist_find_server_by_name into the
4254 files silcd/idlist.[ch].
4256 Added the function silc_idlist_find_server_by_conn into the
4257 files silcd/idlist.[ch].
4259 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * DIE command was renamed to SHUTDOWN. Updated the both code
4264 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4265 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4267 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4270 * Added function silc_server_create_connection function to create
4271 connection to remote router. My server implementation actually
4272 does not allow router to connect to normal server (it expects
4273 that normal server always initiates the connection to the router)
4274 so the CONNECT command is only good for connecting to another
4277 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4280 or some other client was kicked from the channel.
4282 Implemented the handling of the notify type to both client
4285 Implemented silc_server_send_notify_kicked to send the KICKED
4286 notify. It is used to send it to the server's primary router.
4288 * Implemented the KICK command into server and client.
4290 * Added `query' argument to the silc_idlist_get_client function
4291 to indicate whether to query the client from server or not if
4294 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4295 to indicate that the client is not channel founder.
4299 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Removed the rng context from SilcPacketContext structure and
4302 changed that the packet routine uses the Global RNG API.
4304 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added support for quit message that client can "leave" on the
4307 channel when it quits the SILC. It is ditributed inside the
4308 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4310 Added silc_server_free_client_data that will take the
4311 signoff message as argument.
4313 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4315 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Updated parts of the protocol specification to keep it up
4320 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4323 payloads in one packet.
4325 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4326 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4327 use now the new List flag.
4329 * Also deprecated the following packet types: REPLACE_ID,
4330 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4332 * Added list support for Notify packet in server.
4334 * Added silc_server_send_notify_channel_change to send the
4335 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4336 the silc_server_send_replace_id.
4338 * Added silc_server_send_notify_nick_change to send the
4339 NICK_CHANGE notify type. Deprecates the function
4340 silc_server_send_replace_id.
4342 * Added silc_server_send_notify_join to send the JOIN notify type.
4343 Deprecates the function silc_server_send_new_channel_user.
4345 * Added silc_server_send_notify_leave to send LEAVE notify type.
4346 Deprecates the function silc_server_send_remove_channel_user.
4348 * Added silc_server_send_notify_cmode and
4349 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4350 types. Deprecates the silc_server_send_set_mode function.
4352 * Added SERVER_SIGNOFF notify type to indicate that server has
4353 quit. This means that all clients on the channel from that
4354 server will drop. This can be also used when netsplit happens.
4356 Deprecated REMOVE_ID packet type since it is not needed anymore
4359 Added silc_server_send_notify_server_signoff to send the
4360 SERVER_SIGNOFF notify type. Deprecates the function
4361 silc_server_send_remove_id.
4363 Added also silc_server_send_notify_signoff to send the
4364 SIGNOFF notify type.
4366 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4367 SILC protocol from this day on. Changed the protocol
4368 specification as well.
4370 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4371 notify type. It is used between routers to notify about
4372 topic changes on a channel.
4374 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4377 * Partly updated the protocol specification to comply with the
4378 changes now made. It is still though a bit outdated.
4380 * The JOIN notify type now takes one extra argument <Channel ID>.
4381 The packet used to be destined to the channel but now the
4382 JOIN type may be sent as list thus it is impossible to
4383 destine it to any specific channel. By adding this argument
4384 it is again possible.
4386 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Added CREDITS file. The CHANGES and CREDITS file will appear
4389 in the distribution as well.
4391 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4394 types in the server's silcd/packet_receive.c.
4396 * Implemented CMODE and CUMODE to work in router environment.
4398 * Fixed minor encoding and decoding buglet from the
4399 lib/silccore/silcmode.c.
4401 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4404 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4406 * Changed all SilcConfigServer* and silc_config_server* to
4407 SilcServerConfig* and silc_server_config*, respectively.
4410 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Associated the ID (client or server ID) to the Authentication
4413 Payload to avoid any possibility of forging. Updated the
4414 protocol specification and the code accordingly.
4416 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * The RSA key length is now save to the RsaKey context in the
4419 key generation process in lib/silccrypt/rsa.c. The key length
4420 is now used to figure out the maximum size of the block allowed
4421 to be encrypted/signed.
4423 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4424 is equivalent to the silc_mp_mp2bin but does not allocate any
4427 * Changed silc_mp_mp2bin API to take length argument. If it is
4428 non-zero then the buffer is allocated that large. If zero, then
4429 the size is approximated using silc_mp_sizeinbase, which however
4432 * Created Global RNG API which is global RNG that application can
4433 initialize. After initializing, any routine anywhere in the
4434 code (including library) can use RNG without allocating a new
4435 RNG object. This was done to allow this sort of use of the
4436 RNG in code that has no chance to allocate RNG object. All
4437 applications currently allocate this and many routines in the
4438 library use this. Affected file lib/silccrypt/silcrng.[ch].
4440 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4441 it to use the Global RNG API.
4443 * Defined Authentication Payload into protocol specification that
4444 is used during SILC session to authenticate entities. It is
4445 used for example by client to authenticate itself to the server
4446 to obtain server operator privileges.
4448 Implemented this payload into the lib/silccore/silcauth.[ch].
4449 Implemented also routines for public key based authentication
4450 as the new protocol specification dictates.
4452 Moved definitions of different authentication methods from
4453 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4455 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4456 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4457 silc_pkcs_verify_with_hash functions into the file
4458 lib/silccrypt/silcpkcs.[ch].
4460 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * The client entry's userinfo pointer must be always valid.
4463 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4464 will fail since it requires the userinfo. Now, the userinfo
4465 is allocated as "" if actual userinfo does not exist. Actually,
4466 it must exist and it is totally Ok to drop client connections
4467 that does not announce the userinfo. However, we will make
4468 this workaround for now.
4470 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4471 to return the remote port by socket.
4473 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4476 SILC_SERVER_PENDING_EXEC and added an new macro
4477 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4478 data or when error occurs while processing the pending command.
4480 Added new argument `destructor' into silc_server_command_pending
4481 and to the SilcServerCommandPending object. This destructor is
4482 now called after calling the pending callback or if error occurs
4483 immediately. If error occurs the actual pending callback won't
4484 be called at all - only the destructor. The destructor may be
4485 NULL if destructor is not needed.
4487 All this applies for client library code as well. Similar
4488 changes were made there as well for the pending commands.
4490 In the client, the application must now allocate the
4491 SilcClientCommandContext with the silc_client_command_alloc
4494 * Added reference counter to the SilcServerCommandContext. Added
4495 function silc_server_command_alloc and silc_server_command_dup
4498 Same type of functions added to the client library for the same
4501 * Removed the cmd_ident from IDListData away since it is now
4502 global for all connections. It is the command identifier used
4503 in command sending and with pending commands. The affected file
4506 * Added reference counter to the SilcSocketConnection objecet to
4507 indicate the usage count of the object. The object won't be
4508 freed untill the reference counter hits zero. Currently only
4509 server uses this, and client ignores it. The client must be
4510 set to use this too later. The affected files are
4511 lib/silccore/silcsockconn.[ch]. Added also the function
4512 silc_socket_dup to increase the reference counter.
4514 This was mainly added because it is possible that the socket
4515 is removed underneath of pending command or other async
4516 operation. Now it won't be free'd and proper DISCONNECTING
4517 flags, etc. can be set to avoid sending data to connection that
4518 is not valid anymore.
4520 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4521 the connection. After that it sets SILC_SET_DISCONNECTED.
4522 It is, however, possible that the socket data is not still freed.
4523 The silc_server_packet_process now checks that data is not
4524 read or written to connection that is DISCONNECTED. The socket
4525 get's freed when the reference counter hits zero.
4527 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Changed the client operation API: channel_message operation's
4530 `sender' is now the client entry of the sender, not the nickname
4531 and the `channel' is the channel entry, not the channel name.
4533 In the private_message operation the `sender' is now also the
4534 client entry of the sender not the nickname.
4536 Affected file is lib/silcclient/ops.h and all applications
4537 using the client operations.
4539 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Moved the calling of ops->connect() from connect_to_server_final
4542 into receive_new_id functin since that is the point when the
4543 client is actually allowed to send traffic to network. The
4544 affected file is lib/silcclient/client.c.
4546 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4549 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4550 (if needs broadcasting) instead of broadcasting the packets one
4551 by one which would make a burst in the network traffic.
4553 * Added `broadcast' argument to the functions in silcd/server.[ch]
4554 silc_server_create_new_channel[_with_id] to indicate whether
4555 to send New Channel packet to primary router.
4557 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Added new function into the silcd/server.[ch] files:
4560 silc_server_create_new_channel_with_id to create new channel with
4561 already existing Channel ID.
4563 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4564 lib/silccore/silcpacket.h. This packet is used t send list of
4565 Set Mode payloads inside one packet. Server uses this to set
4566 the modes for the channels and clients on those channels, that it
4567 announced to the router when it connected to it. The protocol
4568 specification has been updated accordingly.
4570 * The silc_server_new_channel did not handle the packet coming
4571 from normal server as it normally does not send that. However,
4572 when it announces its channels it does send it. Implemented
4573 the support for that.
4575 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4576 into the file lib/silccore/id.h.
4578 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Fixed memory leaks in the functions silc_idlist_del_client,
4581 silc_idlist_del_channel and silc_idlist_del_server in the file
4582 silcd/idlist.c. All of those leaked like a sieve.
4584 * Fixed some small memory leaks in the client's function
4585 silc_client_notify_by_server.
4587 * Added functions into silcd/server.c: silc_server_announce_clients,
4588 silc_server_announce_channels and silc_server_announce_server.
4589 These functions are used by normal and router server to announce
4590 to its primary router about clients, channels and servers (when
4591 router) that we own. This is done after we've connected to the
4594 These functions effectively implements the following packet types:
4595 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4596 and SILC_PACKET_NEW_ID_LIST.
4598 * Added new functions into the silcd/packet_receive.[ch]:
4599 silc_server_new_id_list, silc_server_new_channel_list and
4600 silc_server_new_channel_user_list to handle the incoming
4601 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4603 * Added support of changing Channel ID in the function
4604 silc_server_replace_id. If the server that announces a channel
4605 to the router already exists in the router (with same name but
4606 with different Channel ID), router is responsible to send
4607 Replace ID packet to the server and force the server to change
4608 the Channel ID to the one router has.
4610 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4611 client that the Channel ID has been changed by the router. The
4612 normal server sends this to the client. Client must start using
4613 the new Channel ID as the channel's ID.
4615 Implemented handling of this new type into lib/silcclient/client.c
4616 into the function silc_client_notify_by_server.
4618 * Added new function silc_idlist_replace_channel_id into the files
4619 silcd/idlist.[ch] to replace the Channel ID.
4621 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Call silc_server_command_identify_check always when processing
4624 the IDENTIFY command in silcd/command.c
4626 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4629 send keepalive packets. The packet can be sent by clients,
4630 servers and routers.
4632 Added function silc_socket_set_heartbeat into the file
4633 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4634 If not set, the heartbeat is not performed. The actual
4635 heartbeat is implemented in the low level socket connection
4636 library. However, application is responsible of actually
4639 Added silc_server_send_heartbeat to send the actual heartbeat
4640 packet into silcd/packet_send.[ch]. Server now performs
4641 keepalive with all connections.
4643 * Added silc_task_get_first function into lib/silcutil/silctask.c
4644 to return the timeout task with shortest timeout. There was a bug
4645 in task unregistration that caused problems. TODO has been
4646 updated to include that task system must be rewritten.
4648 * The client library will now resolve the client information when
4649 receiving JOIN notify from server for client that we know but
4650 have incomplete information.
4652 * Rewrote parts of silc_server_remove_from_channels and
4653 silc_server_remove_from_one_channel as they did not remove the
4654 channel in some circumstances even though they should've.
4656 * Encryption problem encountered in server:
4658 The LEAVE command used to send the Channel Key packet to the
4659 router immediately after generating it. However, the code
4660 had earlier sent Remove Channel user packet but not immediately,
4661 ie. it was put to queue. The order of packets in the router
4662 was that Channel Key packet was first and Remove Channel User
4663 packet was second, even though they were encrypted in the
4664 reverse order. For this reason, MAC check failed. Now, this
4665 is fixed by not sending the Channel Key packet immediately but
4666 putting it to queue. However, this is more fundamental problem:
4667 packets that are in queue should actually not be encrypted
4668 because packets that are sent immediately gets encrypted
4669 actually with wrong IV (and thus MAC check fails). So, packets
4670 that are in queue should be encrypted when they are sent to
4671 the wire and not when they put to the queue.
4673 However, the problem is that the current system has not been
4674 designed to work that way. Instead, the packet is encrypted
4675 as soon as possible and left to the queue. The queue is then
4676 just purged into wire. There won't be any fixes for this
4677 any time soon. So, the current semantic for packet sending
4680 o If you send packet to remote host and do not force the send
4681 (the packet will be in queue) then all subsequent packets to the
4682 same remote host must also be put to the queue. Only after the
4683 queue has been purged is it safe again to force the packet
4686 o If you send all packets immediately then it safe to send
4687 any of subsequent packets through the queue, however, after
4688 the first packet is put to queue then any subsequent packets
4689 must also be put to the queue.
4691 Follow these rules and everything works fine.
4693 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Added new function silc_server_remove_clients_by_server to
4696 remove all client entries from ID list when the server connection
4697 is lost. In this case it is also important to invalidate all
4698 client entires as they hold the invalid server entry. This
4699 fixes fatal bug when server has lost connection and will reconnect
4702 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Made some sanity checks to silc_server_daemonise like to check
4705 whether the requested user and group actually exists.
4707 * Added sanity check to SKE's silc_ske_responder_finish to check
4708 that the public and private key actually is valid.
4710 * Invalidate the client's nickname when receiving Replace ID
4711 packet and the Client ID is being replaced. This means that the
4712 server will query the nickname if someone needs it (client)
4715 * Sort the ID Cache in client library when the ID Cache data
4716 has changed (needs sorting).
4718 * Do not allow for SILC client to create several connections to
4719 several servers. The client does not support windows right now
4720 and generating multiple connections causes weird behaviour.
4722 Irssi-silc client does support windows and can handle several
4723 connections without problems, see: www.irssi.org and SILC plugin.
4725 * Fixed some places where client was added to the IDList. The
4726 rule of thumb is following (in order to get everything right):
4727 If the client is directly connected local client then the
4728 `connection' argument must be set and `router' argument must be
4729 NULL to silc_idlist_add_client function. If the client is not
4730 directly connected client then the `router' argument must
4731 bet set and the `connection' argument must be NULL to the
4732 silc_idlist_add_client function.
4734 * The funtion silc_server_packet_send_local_channel actually did
4735 not check whether the client was locally connected or not. It
4736 does that now. Fixed a bug related to LEAVE command.
4738 * Fixed Remove Channel User payload parsing bug in server's
4739 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4741 * The server's silc_server_save_channel_key now checks also the
4742 global ID list for the channel as it might not be in the local
4743 list. Fixed a bug related to LEAVE command.
4745 * Is this the end of the [<unknown>] buglet that has been lurking
4746 around for a long time? A little for loop fix in server's
4747 silc_server_command_whois_parse that is used by both IDENTIFY
4748 and WHOIS command. At least, this was a clear bug and a cause
4749 of one type of [<unknown>] buglet.
4751 * WHOIS and IDENTIFY commands call the function
4752 silc_server_command_[whois/identify]_check function even if
4753 we are not router server.
4755 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added --with-gmp configuration option. If set the GMP
4758 is always compiled in the SILC source tree. If not set then
4759 it is checked whether the system has the GMP3 installed. If
4760 it has then the GMP won't be compiled (the system's headers
4761 and library is used), if it doesn't have it then the GMP is
4762 compiled in the SILC source tree.
4764 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Changed RSA private exponent generation to what PKCS #1
4767 suggests. We try to find the smallest possible d by doing
4768 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4769 not security fix but optimization.
4771 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Added new config entry [Identity] to fork the server and run
4774 it as specific user and group. A patch from Bostik.
4776 * Imported Dotconf configuration library into lib/dotconf.
4777 This will be used to create the SILC configuration files later.
4778 It will appear in the distsribution after this commit.
4780 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * A big code auditing weekend happening. Auditing code for
4783 obvious mistakes, bugs and errors. Also, removing any code
4786 Removed files for being obsolete:
4788 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4789 inline in the file lib/silcutil/silcbuffer.h)
4791 o lib/silcutil/silcbufutil.c (the header has inline versions)
4793 Changed code to fix possible error conditions:
4795 o The buffer formatting routines now check that the destination
4796 buffer really has enough space to add the data. This applies for
4797 both buffer formatting and unformatting
4798 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4799 unformatting was changed to accomodate following rules:
4800 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4801 sent to the function while XXX_*STRING will not allocate or copy
4802 the data into the buffer. Instead it sets the pointer from the
4803 buffer into the pointer sent as argument (XXX_*STRING used to
4804 require that the pointer must be allocated already). This change
4805 makes this whole thing a bit more consistent and more optimized
4806 (note that the data returned in the unformatting with XXX_*STRING
4807 must not be freed now). The routines return now -1 on error.
4809 o Tried to find all code that use buffer_format and buffer_unformat
4810 and added return value checking to prevent formatting and
4811 especially unformatting errors and possible subsequent fatal
4814 o Changed ske->x and ske->KEY to mallocated pointers in
4815 lib/silcske/silcske.h. Fixed possible data and memory leak.
4817 o Added return value checking to all *_parse* functions. Fixed
4818 many memory leaks as well.
4820 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4821 so that buffer overflows would not happen. All code now also
4822 checks the return value as it can fail.
4824 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Added reconnection support to server if the normal server looses
4827 its connection to the router (for example if router is rebooted).
4828 The server performs normal reconnection strategy implemented
4829 to the server. Affected file silcd/server.c.
4831 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Added new packet type SILC_PACKET_SET_MODE that is used to
4834 distribute the information about changed modes (for clients,
4835 channels and clients channel modes) to all routers in the
4836 network. Updated the protocol specification accordingly.
4838 Added functions into silcd/packet_send.c and
4839 silcd/packet_receive.c: silc_server_send_set_mode,
4840 silc_server_set_mode.
4842 Added new files silcmode.[ch] into lib/silccore that implements
4843 the encoding and decoding of Set Mode Payload. Added new type
4844 SilcSetModePayload. Moved the definitions of different modes
4845 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4847 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Oops, a little mistake in server's connection authentication
4850 protocol. The protocol is not ended with FAILURE but with
4851 SUCCESS if the authentication is Ok. :) Affected file is
4854 * Implemented NICK_CHANGE notify handling in server in the file
4855 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4856 the local clients on the channel. After the changing nickname
4857 in router environment snhould work and the [<unknown>] nickname
4858 should appear no more.
4860 The silc_server_replace_id function that receives the Replace ID
4861 payload now sends the NICK_CHANGE notify type also in the file
4862 silcd/packet_receive.c
4864 * Changed WHOIS and IDENTIFY command to support the maximum amount
4865 of arguments defined in protocol specs (3328 arguments). This
4866 fixed a bug that caused problems when there were more than three
4869 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added extra parameter, command identifier, to the
4872 silc_client_send_command so that explicit command identifier
4875 Changed that ID list routines uses specific command identifier
4876 when sending WHOIS/IDENTIFY requests to the server so that they
4877 can be identified when the reply comes back.
4879 Affected files lib/silcclient/command.[ch],
4880 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4882 * Added `sender' argument to silc_server_packet_send_to_channel
4883 to indicaet the sender who originally sent the packet to us
4884 that we are now re-sending. Ignored if NULL. Affected file
4885 silcd/packet_send.[ch].
4887 * Added some server statistics support in silcd/server_internal.h
4888 SilcServerStatistics structure and around the server code. Also
4889 send some nice statistics information when client is connecting
4892 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * Fixed channel ID decoding in server's JOIN command reply in
4895 silcd/command_reply.c
4897 * Fixed braodcasting of replace ID payload to not to send it if
4898 we are standalone server in silcd/packet_receive.c.
4900 * Fixed all channel message sending routines to not to send
4901 packets to clients that has router set, since they are routed
4902 separately in the same function earlier. Affects file
4903 silcd/packet_send.c and all channel packet sending functions.
4905 * In USERS reply, res_argv[i] are not allocated, the table
4906 is allocated. Thus changed that free the table, not its
4909 * In server's whois_check and identify_check if the client is
4910 locally connected do not send any WHOIS commands - they are not
4913 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4915 * Fixed some minor bugs in client when sending WHOIS command. The
4916 arguments was in wrong order.
4918 * Removed statis function add_to_channel from server in
4919 silcd/command.c that was previously used with the joining but
4922 * Tested USERS command in router environment successfully with two
4923 routers, two servers and two clients.
4925 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Reorganized the USERS command and command reply in client library
4928 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4929 When the command is given by user we register a pending command
4930 callback that will reprocess the command after the reply has been
4931 received from the server. When reprocessing the packet we then
4932 display the information. Thus, the USERS information is displayed
4933 now in the command callback instead of in the command reply
4934 callback. The processing of the command is same as previously
4935 when server has sent the command reply in the JOINing process.
4937 * Added to USERS command in silcd/command_reply.c to join the client,
4938 we didn't use to know about, to the channel after we've created
4939 a client entry for it. Also, for clienet we did know already still
4940 check whether it is on the channel or not and add it if not.
4942 * Removed silc_server_command_join_notify as the function and its
4945 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Changed the client's pending command handling to the same as the
4948 server's pending command handling. It is also now possible to
4949 execute command reply functions from other command reply
4950 function as the function callbacks for commands and command
4951 replies are one and same. The pending commands are not static
4952 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4953 in client connection context. Thus, pending commands are server
4954 connection specific as it is convenient.
4956 Changed the function silc_client_command_pending and
4957 silc_client_command_pending_del and added new function
4958 silc_client_command_pending_check. Removed the
4959 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4962 * Added cmd_ident, current command identifier, to the client
4963 connection context in lib/silcclient/client.h to keep track on
4964 command identifiers used in command sending. Client's command reply
4965 function handling now supports the mandatory command identifiers.
4967 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4968 funtions in client to fully support pending command callbacks.
4970 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4971 as one of the arguments to the application in the command reply
4974 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4975 before first releasing SILC but came back. Now it is removed again
4976 and should come back nomore. The FORWARDED flag was used only
4977 by the JOINing procedure by forwarding the command packet to router.
4978 Now, the JOINing procedure has been changed to more generic (due
4979 to various router environment issues) and FORWARDED is not needed
4980 anymore for anything. The protocol specification is yet to be
4983 Now, removed silc_server_packet_forward from server and the flag
4984 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4986 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Renamed NAMES command to USERS command. The NAMES was named that
4989 due to historical reasons. Now it is renamed. Also, rewrote
4990 parts of the USERS command. The nickname list is not sent anymore
4991 by the server. Only Client ID and mode lists are sent in the USERS
4992 command. Changed this also to the protocol specification.
4994 The client now resolves the names and stuff after it receives
4995 the USERS list from the server when joining to the channel.
4997 * WHOIS and IDENTIFY commands has been changed to support multiple
4998 Client ID's per command. One can now search for multiple users
4999 in the network by sending only one WHOIS or IDENTIFY command.
5000 Changed the code and the protocol specifications.
5002 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5003 uses silc_server_command_whois_parse to parse the request. */
5005 * If normal server, do not parse the WHOIS and IDENTIFY requests
5006 before sending it to the router. Saves some time.
5008 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Fixed JOIN command on client library. Wrong number of arguments
5011 used to crash the client.
5013 * Added silc_server_channel_has_global function to check whether
5014 channel has global users or not.
5016 * Added silc_server_channel_has_local function to check whether channel
5017 has locally connected clients on the channel.
5019 * The silc_server_remove_from_one_channel now checks whether the
5020 channel has global users or not after given client was removed from
5021 the channel. It also checks whether the channel has local clients
5022 on the channel anymore. If it does not have then the channel entry
5023 is removed as it is not needed anymore.
5025 * The silc_server_notify now checks on JOIN notify whether the joining
5026 client is one of locally connected or global. If it is global then
5027 the channel has now global users on the channel and that is marked
5028 to the channel entry. Also, it now saves the global client to
5029 global list who is joining and JOINs it to the channel. This is
5030 for normal server, that is.
5032 Changed silc_server_send_notify_on_channel,
5033 silc_server_packet_relay_to_channel and
5034 silc_server_packet_send_to_channel check if we are normal server
5035 and client has router set (ie. global client) do not send the
5036 message to that client, as it is already routed to our router.
5038 * Implemented LEAVE notify type handling in silc_server_notify
5041 * Tested LEAVE command in router environment successfully. Tested
5042 with two routers, two servers and two clients.
5046 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5048 * Implemented SIGNOFF notify type handling in silc_server_notify
5051 * silc_server_remove_id now removes the client entry from all channels
5052 it has joined and thusly sends SIGNOFF notify type.
5054 * Rewrote the NAMES list generation in server by removing two excess
5055 loops. The lists are created now inside one loop.
5057 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * silc_server_remove_channel_user checks now also global list
5060 for channel and client.
5062 * silc_server_new_channel_user checks now both local and global
5063 list for channel and client. Fixed a bug in client id decoding.
5064 Used to decode wrong buffer.
5066 * silc_server_channel_message checks now both local and global
5067 list for channel entry.
5069 * Tested channel joining (hence JOIN) in router environment
5070 successfully. Tested with two routers, two servers and two
5073 * Tested channel message sending in router environment successfully.
5075 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Added silc_server_save_channel_key into server.[ch] to save the
5078 received channel key in Channel Key payload processing. It is
5079 also used in JOIN command reply handling.
5081 Equivalent function silc_client_save_channel_key added into
5082 client.[ch] into client library.
5084 * Changed JOIN command reply to send information whether the channel
5085 was created or not (is existing already) and the channel key
5086 payload. Changed protocol specs accordingly.
5088 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5089 the request was sent by ID and not by nickname. Crashed on
5092 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5095 now correctly save the received data.
5097 * silc_server_free_sock_user_data now notifies routers in the
5098 network about entities leaving the network.
5100 At the same time implemented functions silc_server_remove_id
5101 and silc_server_send_remove_id to receive and send REMOVE_ID
5102 packets. The packet is used to notify routers in the network
5103 about leaving entities. The ID removed will become invalid in
5106 * Added function silc_idlist_del_server into server. Removes and
5107 free's server entry from ID list.
5109 * silc_server_private_message function now checks, if we are router,
5110 that the destination ID really is valid ID, naturally.
5112 * In router when NEW_ID packet is received (for new client) the
5113 hash of the Client ID is saved in the ID Cache but the
5114 client->nickname is set to NULL, instead of putting the hash
5117 IDENTIFY command now also checks that client->nickname must be
5118 valid. If it is not if will request the data from the server who
5119 owns the client. Added new function
5120 silc_server_command_identify_check.
5122 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5123 to set the command to already allocated Command Payload.
5125 * Tested private message sending in router environment with two
5126 routers, two servers and two clients. Fixed minor bugs and now
5129 * Fixed segfault from client's NAMES command. Used to crash if
5132 * Forwarded packets must not be routed even if it is not destined
5133 to the receiver. Changed server code comply with this.
5135 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Added `require_reverse_mapping' boolean value to ServerParams
5138 structure. If TRUE (not default) the server will require that
5139 the connecting host has fully qualified domain name.
5141 If the reverse mapping is not required and hostname could not be
5142 found the IP address is used as hostname.
5144 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Implemented version string checking to both client and server.
5147 The check is incomplete currently due to the abnormal version
5148 strings used in development version of SILC.
5150 * Changed all command functions in server to use the new
5153 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Changed char *data to unsigned char *data in ID Cache system to
5156 support binary data as ID Cache data. Changed code to support
5157 binary data in lib/silccore/idcache.c.
5159 * Renamed silc_server_packet_relay_command_reply to
5160 silc_server_command_reply as it is normal packet receiving
5161 function. Rewrote the function to accept command replys for
5162 servers and not only for clients.
5164 * Mark remote router always as registered server if we are connecting
5165 to it. Otherwise, commands sent by the router to us are ignored.
5167 * All ID List find routines now returns the ID Cache Entry pointer
5168 as well if requested.
5170 * WHOIS command works now in router environment, tested with two
5171 routers, two servers and two clients.
5173 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5174 in router environment (as it is almost equivalent to WHOIS) but
5175 hasn't been tested thoroughly. Added new functions:
5177 silc_server_command_identify_parse
5178 silc_server_command_identify_send_reply
5179 silc_server_command_identify_from_client
5180 silc_server_command_identify_from_server
5182 * Disabled route cache adding because adding two different ID's with
5183 same IP replaces the old cache entry thus giving wrong route.
5184 The entry->router->connection is always the fastest route anyway
5185 so route cache may not be needed. Of course, new routes maybe
5186 established after receiving the ID when the entry->router->connection
5187 might not be anymore the most optimal.
5189 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Add route cache for received ID for fast routing.
5193 * Added silc_server_packet_route to route received packet on router
5194 that is not destined to us.
5196 * Renamed silc_server_get_route to silc_server_route_get.
5198 * Added id_string and id_string_len fields into SilcServer to
5199 include encoded ServerID for fast comparing without excess
5200 encoding of the ID's.
5202 * Cleaned up WHOIS command on server side. Added following static
5205 silc_server_command_whois_parse
5206 silc_server_command_whois_check
5207 silc_server_command_whois_send_reply
5208 silc_server_command_whois_from_client
5209 silc_server_command_whois_from_server
5211 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5212 arguments in command replies. All command functions should be
5213 updated to use this macro.
5215 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * Minor typo fixes on command reply handling on server.
5219 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Added silc_server_command_add_to_channel internal routine to add
5222 the client to the channel after router has created the channel and
5223 sent command reply to the server.
5225 * Added generic silc_server_send_command to send any command from
5228 * Use static buffer with ID rendering instead of duplicating data.
5230 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Fixed a channel user mode bug when joining to a channel server gave
5233 everybody channel founder rights, oops.
5235 * We mark ourselves as the router of the incoming server connection
5236 if we are router ourselves. This way we can check in some packet
5237 sending functions whether it is locally connected server. For
5238 incoming router connections we put NULL.
5240 * For router sending packets locally means now always sending the
5241 packet cell wide; to local clients and local servers. For normal
5242 server sending packet locally means sending it to only local
5245 * Fixed the JOIN command to really work in router environment. If the
5246 channel is created it is always created by the router. Router is
5247 also responsible of making the initial joining to the channel,
5248 sending JOIN notify to the sending server and distributing
5249 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5250 does not exist server doesn't do anything else but forward the
5251 command to the router which performs everything.
5253 * Added silc_server_send_channel_key function to send the Channel Key
5256 * Added silc_server_create_channel_key to create new channel key. The
5257 channel key is now re-generated everytime someone joins or leaves
5258 a channel, as protocol dictates. Note: channel->key_len is the
5261 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5263 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5264 packet_receive.[ch] to separate packet sending and receiving
5265 routines. The server.[ch] now includes everything else including
5266 actual packet processing (writing and reading data) and other
5269 Renamed silc_server_private_message_send_internal to
5270 silc_server_send_private_message. The routine is still though
5271 used only to relay private messages as server does not send
5272 private messages itself.
5274 Renamed silc_server_new_channel to silc_server_create_new_channel
5275 and added new function sicl_server_new_channel that handles the
5276 incoming New Channel packet. Added also new sending function
5277 silc_server_send_new_channel to send New Channel Payload.
5279 * Added new function silc_server_notify to process incoming notify
5280 packet to the server/router. Server may then relay the notify
5281 to clients if needed.
5283 * Added new function silc_server_new_channel_user to process incoming
5284 New Channel User packet. Router will redistribute the packet and
5285 send JOIN notify to its local clients and locally connected servers
5286 if needed. Normal server will send JOIN notify to its local client
5287 on same channel when received this packet. Added also corresponding
5288 sending function silc_server_send_new_channel_user to sent the
5291 * Added boolean route argument to send_notif_to_channel and
5292 packet_send_to_channel functions to attempt to route the packet
5293 if it is TRUE and send only locally if it is FALSE.
5295 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * silc_server_replace_id now broadcasts the received replace ID
5298 packet if it is not broadcast packet already. The router must
5299 broadcast to inform other routers about changed ID.
5301 * Added backpointer to server's router into SilcServer context in
5302 silcd/server_internal.h.
5304 * Fixed silc_server_packet_broadcast to send correct broadcast
5307 * The channel key is now distributed to the local client as soon
5308 as it is received from the router (in router environment) so that
5309 no other packet may be sent for the channel until client has
5312 * silc_server_remove_channel_user now broadcasts the received
5313 Remove Channel User packet if it is not broadcast packet already.
5314 The router must broadcast to inform other routers about removed
5317 * Added users field into SilcPacketContext that is a reference count
5318 of the context. One can increase the reference count by calling
5319 silc_packet_context_dup which is now changed to just increase the
5320 reference count instead of duplicating the data. The reference
5321 count is decresed by calling silc_packet_context_free that will
5322 free the data after the reference count hits zero.
5324 For now on the packet context and everything allocated into it
5325 (including the raw packet from network) must be freed by calling
5326 the new silc_packet_context_free function. Added also new function
5327 silc_packet_context_alloc that must be used now to allocate the
5328 context. This also means that if a routine is asynchronous from
5329 silc_[client/server]_packet_parse_type the packet context must
5330 be duplicated by calling silc_packet_context_dup. Otherwise it
5331 gets free'd after silc_[client/server]_packet_parse_type returns.
5332 Also, one must remember that if packet is duplicated then its
5333 reference count must be decresed by calling the free function as
5334 many times as it was duplicated.
5336 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5337 from both client and server.
5339 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Made joining to a channel working in router environment.
5343 * Cleaned up JOIN command on server side and create function
5344 silc_server_command_join_channel internal routine to make the
5347 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Changed silc_command_pending list to SilcDList. Also, added
5350 `ident' field to SilcServerCommandPending structure to identify
5351 the reply and to call correct callback.
5353 Added silc_server_command_pending_check function to replace the
5354 corresnponding macro. The silc_command_pending list is not
5357 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5358 to set identifier to previously allocated Command Payload. It
5359 is used to set identifier for command when resending Command
5362 * Added silc_command_payload_encode_payload to encode Command
5363 Payload buffer from SilcCommandPayload structure.
5365 * Added silc_argument_payload_encode_payload to encode Argument
5366 payload buffer from SilcArgumentPayload structure.
5368 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Changed WHOIS command to support router connection on server side.
5371 The whois request is always sent to router unless the server is
5372 standalone server. After server has received the reply from the
5373 router will it send the reply to the client.
5375 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5376 broadcast received broadcast packet. The function is used only
5377 by router. The broadcast packet is always sent to the router's
5380 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5381 render given ID to printable string, for log files for example.
5383 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Made basic router to router connections working. At least they
5386 can now connect to each other but nothing really works the way
5387 they are supposed - yet.
5389 * Added new initiator token to RouterConnection configuration
5390 file in silcd/serverconfig.[ch]. It is used to tell whether we
5391 are the initiator to the remote router or whether we'll expect
5392 the other end to connect.
5394 * Moved registering of listener task to silc_server_init, hence
5395 the server starts listenning as soon as it is run, even if it
5396 does not have connections to other routers. Let's see how well
5399 * Changed default connection retry timeouts for more suitable in
5402 * Removed cipher and such arguments from silc_idlist_add_client
5403 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5404 Added new function silc_idlist_add_data to add the keys and stuff
5407 * Added SilcIDListData structure and added it to SilcClientEntry
5408 and SilcServerEntry as their first field in the structure. This
5409 way we can explicitly cast the ID entries to the SilcIDListData
5410 structure and get common data for the entries. In past, we had
5411 to first check what type of connection it is and then cast it to
5412 correct ID entry type. Now, we can directly cast the opaque
5413 pointer to the SilcIDListData (no matter what ID entry it actually
5414 is) and get the data needed.
5416 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5419 in some circumstances even if threre were timeout tasks, though not
5420 IO tasks, but tasks anyway. Now fixed.
5422 * Defined SilcServerConnection structure to hold connection specific
5423 stuff about directly connected servers and routers. The definition
5424 is currently in silcd/server_internal.h. I thought about having
5425 a bit more important role fro this struct but for now it is used
5426 only when connecting to other server (or router actually).
5428 * Added connecting retry support in server when connecting to
5429 router(s). The retry feature implement exponential backoff
5430 algorithm. Also, added SilcServerParams structure to hold default
5431 parameters for server. For now, it include these retry settings
5432 and are hard coded. After server is moded to be as Silc Server
5433 Library this structure will be more important.
5435 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Changed client librarys channel->clients table to SilcList and
5438 changed code accordingly.
5440 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Changed client's channel table to SilcList and changed code
5443 accordingly. Also changed SilcChannelClientEntry to include back-
5444 pointer to the channel so that client entry can use that structure
5445 as list as well and we have fast cross-reference to the channel.
5446 This change dramatically decreased the complexity of channel
5447 handling with client entry and vice versa (removed one extra
5448 loop when searching for channel entry from many functions).
5450 * Changed server->sim from table to SilcDList and changed code
5453 * NAMES command can now be used from user interface. It will show
5454 the user list on the channel, neatly.
5456 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5457 Code now saves realname of the user if it becomes available.
5459 * Renamed configure.in to configure.in.pre and made ./prepare
5460 script to automatically add correct version string to
5461 configure.in which it creates from configure.in.pre.
5463 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * NAMES command reply now shows users mode with the nickname when
5468 * Moved silc_client_ch[u]mode[_char] functions from
5469 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5470 place sucks, they are utility functions and should be in some
5473 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5475 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5478 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added TRQ (efficient deque and list library) into lib/trq. This is
5483 a very good list library that is currently used in the SILC. Defined
5484 SilcList API over the library because I didn't like the API very
5485 much. See lib/trq/silclist.h for the API and examples of how to
5486 use the API. Fixed various places in the code to use the new
5487 SilcList API. The SilcList is meant for lists that has a structure
5488 already defined as a list. It is not suitable to add just some
5489 context to the list (in TRQ, the context is the list actually).
5491 So, I defined SilcDList that can be used for the purpose where
5492 predefined list structure does not exit. This can be used as
5493 such list. Now some context just can be added to the SilcDList.
5494 Currently this list is not used in the SILC just yet, though there
5495 are a lot places where this can replace dynamically allocated
5496 tables and I will fix these places, later, to use SilcDList.
5497 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5498 and use TRQ internally).
5500 Also fixed some annoying warning messages that the original TRQ
5501 code generated. Also minor changes to TRQ's Makefile.in.
5503 * Added support for querying by Client ID to both WHOIS and
5504 IDENTIFY commands into server, as required by the protocol.
5506 * Removed method function pointers from SilcBuffer structure. They
5507 weren't used to anything and just increased the context size for
5508 no good reason. This change also made silc_buffer_alloc and
5509 silc_buffer_free functions inline functions.
5511 * Disabled command flooding detection support until it's fixed so
5512 that it accepts commands in but does not execute them more than once
5515 * Added silc_net_localhost(), to return local hostname, into
5516 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5517 that must be initialized before calling silc_client_init.
5519 * Added new function: silc_server_send_notify_on_channels to send
5520 notify messages to all channels client has joined. It is assured
5521 that the message is sent only once per client.
5523 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5524 lib/silcutil/silcutil.[ch] as silc_format function. The new
5525 function is generic and is used by server as well, not only by
5526 the logging routines.
5528 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5529 the provided version string was not acceptable. Added new function:
5530 silc_ske_check_version into lib/silcske/silcske.h. The function
5531 must be implemented by the application (client or server) and it
5532 does not reside in the SKE library. The function checks the version
5533 string remote end sent.
5535 * Added back pointers (to opaque context and to SilcSocketConnection)
5536 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5538 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5539 duplicate packet context structure.
5541 * Changed `notify' client operation to send same arguments as client
5542 receives from server except for ID's. ID's are mapped to correct
5543 ID entry and that is returned. Also, if channel entry is not sent
5544 by server but the notify is for channel the channel entry is sent
5545 to application (otherwise application doesn't know that it is for
5546 channel (library gets it from packet's Destination ID)).
5548 * Added silc_client_remove_from_channels into client library to
5549 remove a client from all channels it has joined to. Used when
5550 received SIGNOFF notify from server. Added also new function
5551 silc_client_replace_from_channels to replace old ID entry with
5552 new ID entry on all channels. Used when received NICK_CHANGE
5555 * Fixed ID Cache list handling in silc_idlist_get_client in
5556 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5557 to get (or query) client by ID.
5559 * Updated TODO list.
5561 * Added connection authentication status message defined by the
5562 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5563 support for these into the code in client and server side.
5565 * Added generic function silc_client_send_command to send any command
5566 with variable argument list. Application should use this function
5567 to send commands if the command functions provided by the library
5568 does not suite for the application's user interface needs.
5570 * Added new `failure' client operation. Application is notified about
5571 received failure packet if client is executing a protocol. In this
5572 case the protocol's execution has failed.
5574 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5575 is required by the protocol.
5577 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5578 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5581 * Added status flag to SilcSKE object to indicate realtime status
5582 of the SKE protocol.
5584 * Application receives now exactly same command reply arguments as
5585 the library receives from server. However, if ID is received the
5586 corresponding ID entry is returned to the application (eg. Client
5587 ID is mapped to correct SilcClientEntry entry and that is returned).
5588 Changed command_reply client operation due to this change.
5590 * Changed all ID's in commands and in command replys as ID Payloads.
5591 Change affected both client and server side codes.
5593 All ID's sent in SILC network (with execption of ID's in SILC
5594 Packet header) are sent in ID Payload to support variable length
5597 * Server now notifies nick changes and notifies all clients on
5598 the channels about the new nickname (about the new Client ID,
5601 * Implemented CMODE command to change channel modes. Supports all
5602 channel modes defined by the protocol specs except ban and invite
5603 lists. (Also, private channel key mode is supported but support for
5604 setting private channel key in client is missing, thus, this mode
5605 has no effect on client side (except that server requires that the
5606 client uses private channel key and normal channel traffic does not
5609 Also, invite mode works per se, but INVITE command does not work
5610 yet correctly, so you can set channel as invite only channel but
5611 inviting clients to the channel does not work (it is yet to be
5612 thought what's the best way to do it).
5614 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5615 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5616 Implemented CUMODE command to change user's mode on the channel.
5617 Supports all modes defined by the protocol specs.
5619 * Added NAMES command reply to return users modes on the channel.
5621 * Removed unnecessary and slow ciphers from lib/silccrypt.
5623 * Set SO_KEEPALIVE option to connection sockets by default.
5625 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5627 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5628 redefined the Notify Payload into protocol specs.
5630 * Added silc_id_payload_parse_id to get ID directly from raw
5633 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5636 accept searching by Client ID as well.
5638 * Added support for LEAVE and SIGNOFF notify types in client library.
5640 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5641 to parse ID Payload from raw data.
5643 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added flags parameter into silc_ske_assemble_security_properties
5646 function in lib/silcske/silcske.[ch].
5648 * Changed notify client operation to fit better for notify messages
5649 sent by server. The notify payload received from server is now
5650 passed to the application (after parsing it to SilcNotifyPayload).
5651 It is application's responsibility to retrieve the arguments
5652 from the payload and show the message the way it wants. The message
5653 sent by server is implementation specific.
5655 * Changed public keys to comply with the protocol specification.
5656 Old public keys are not supported anymore and are not compatible.
5658 * Removed nickname from Channel Payload as the latest draft removed
5659 it. The client must resolve the nickname from the NAMES command
5660 reply received when it joined the channel.
5662 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5664 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Fixed some errors in protocol specification drafts.
5668 * Created lib/silccore/silcnotify.c to implement Notify Payload
5669 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5670 generic payloads described by protocol specifications. The file
5671 includes implementations for ID Payload and Argument Payload.
5673 * Changed Command Payload implementation to use the new Argument
5674 Payload. Changed command_xxxx_payload to command_payload_xxxx
5675 to comply with SILC coding conventions.
5677 * Added suppport for Argument Payload handling in Notify Payload
5678 implementation as protocol requires it. Added the new support
5679 into server and client lib as well.
5681 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5683 * Added support for multiple nicknames on same channel. [n] is
5684 added locally to the nickname if there are more than one same
5685 nicknames on the channel.
5687 * Server now sends all nicknames that matched WHOIS request.
5688 Client also shows the list received from server.
5690 * Added TOPIC command to client side. User can now set and show
5691 current topic on channel.
5693 * Added MOTD command to client and server. Also, server sends the
5694 motd when client connects to the server.
5696 * Changed version strings to comply ISO 8601.
5698 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Fixed protocol error handling in client library. It should now
5701 cope even if the SKE fails for some reason.
5703 * Made new protocol specification drafts for submitting to IETF.
5705 * Implemented TOPIC command to server in silcd/command.c.
5707 * Added two new notify types into lib/silccore/silcnotify.h:
5708 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5709 notify nickname change and topic setting/change on a channel.
5711 * API change of command_reply operation in client library. The
5712 application gets now the status type received from server as well.
5714 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5718 * Cras fixed and optimized the packet handling even further and
5719 it should work now. Minor change to the prototype of function
5720 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5722 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Added new function into lib/silcutil/silcschedule.[ch]:
5725 silc_schedule_with_fd to select() a specified fd. The function
5726 returns after timeout expires or data arrives or goes. The
5727 function is used by packet routines to wait that all data is
5728 received from network.
5730 * Fixed data reading from network in lib/silccore/silcpacket.c.
5731 The code now assures that all data is read from the fd and then
5732 continues packet processing. This was a bug fix since the code
5733 used to drop some data in some circumstances.
5735 * Added new function into lib/silcclient/client.[ch]:
5736 silc_client_start_key_exchange to start key exchange after
5737 connection has been established to server. The code internally
5738 now uses this funtion but its main purpose was to provide it
5739 for applications that perform their own connecting. After
5740 application has created a connection it merely calls this
5741 function to start the key exchange between client and server.
5742 The library takes care of everything else after that.
5744 Updated also lib/silcclient/README to explain the usage of
5747 * Do not send to application information that connection has
5748 been established. Application gets notified it by connect
5751 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Applied cras's patch to add silc_schedule_one function. The
5754 function runs scheduler once and returns.
5756 * Fixed the scheduler after cras messed it up. The timeout
5757 handling works now as it's supposed to work.
5759 * Added into lib/silccore/ silcnotify.h to include notify
5760 message types support. Changed silc_server_send_notify*
5761 functions, in server.[ch], to support those new notify types.
5762 Added the support for the notify types into client library,
5763 as well. Added new notify client operation into ops.h in
5766 * Changed silc_server_packet_send_to_channel to send normal
5767 packets instead of just channel message packets. The function
5768 is now used to send the notify packets to channels. It is not
5769 used to send channel message packets anymore, as server never
5772 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5773 va_arg()s as it seems to require it nowadays. I guess, if SILC
5774 is compiled with older va_arg() the new code should work anyway.
5776 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Splitted core library. Core library (lib/silccore) includes
5779 now only SILC protocol specific core (and common) components.
5780 Created new utility library (lib/silcutil) that includes more
5781 generic purpose stuff. The stuff for util library was taken
5782 from the old core library. This was minor and easy split.
5784 * Created SILC Client Library (lib/silcclient) that includes
5785 implementation of the SILC client without user interface. This
5786 was major move from silc/ directory. The code has been changed
5787 so that it is transparent towards the user interface. The
5788 silc/ directory includes now the same user interface as before
5789 and it uses the new client library. Read lib/silcclient/README.
5790 Basicly, the client library performs everything else related
5791 to SILC except user interface handling. Also, configuration
5792 files are considered to be part of user interface and library
5793 does not handle them.
5795 This change also changed a lot of structures, function naming etc.
5796 Most important change was that SilcClientWindow object was
5797 renamed to SilcClientConnection in the client library. Created
5798 also new file lib/silcclient/ops.h. Also added new files
5799 silc/local_command.[ch] and silc/client_ops.[ch].
5801 All these changes were made to make it easier for user interface
5802 designers to create what ever user interface for the SILC client
5805 It is also expected that the server will be moved to lib
5806 directory as well and SILC Server Library will be created;
5807 sometimes in the future.
5809 * Removed Local commands from lib/silccore/silccommand.h as
5810 they are application specific and new client library does not
5811 handle any of those anymore.
5813 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5814 old client implementation in silc/.
5816 * Added support for callback functions in SILC_LOG_* macros.
5817 Application can now set its own callbacks that will be called
5818 instead of using the default functions that will always print
5819 the debug messages to stderr (or stdout). Also, debugging can
5820 now be disabled by setting silc_debug to FALSE and re-enabled by
5821 setting it to TRUE. Note, that logging will still work even
5822 if debugging is disabled.
5824 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5825 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5826 silc_log_reset_debug_callbacks.
5828 * To enable debugging in silc client one must give now -d
5829 option on command line.
5831 * Changed silc_schedule_init to automatically allocate task queues
5832 if they are not allocated before calling it.
5834 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Added GMP 3.1 into math library.
5838 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5841 a channel in SILC network. The packet is used by servers and
5842 routers to notify other routers that user has left a channel.
5843 This little feature was missing until now. Added the feature
5844 to protocol specification as well.
5846 Added functions: silc_server_send_remove_channel_user and
5847 silc_server_remove_channel_user into server.[ch].
5849 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5850 lib/silccore/silcpacket.h. However, they are not implemented
5853 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Fixed joining to a channel and sending channel messages
5856 between server and router. The channel message sending should
5857 now work inside a cell.
5859 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Fixed the private message sending between server and router.
5862 The private message sending should now work inside a cell.
5864 * Added silc_server_replace_id into server.[ch] to replace
5865 existing ID in the SILC network.
5867 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5868 and silc_idlist_replace_server_id into idlist.[ch] in server.
5870 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Fixed the server to server connections. Server can again now
5873 connect to router. Router to router connections probably does
5876 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added dynamic protocol registering support. Now protocols can
5879 registered and unregistered on the fly. Patch by cras.
5881 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added lib/contrib directory to hold routines that some platforms
5884 don't have but are needed by SILC.
5886 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5887 into lin/contrib to provide getopt() and getopt_long() for
5888 those who don't have it.
5890 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added AWAY command to client. When away message is set and
5893 client receives a private message packet the client automatically
5894 replies to the sender with the away message.
5896 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5897 bug seemed to be the cause of recent problems when compiling
5900 * Added version detection support to SKE protocol specification
5901 and added the new changes to the SKE implementation as well.
5902 There were other minor changes in the SKE protocol as well.
5904 Many changes in lib/silcske/silcske.[ch] and in
5905 lib/silcske/payload.[ch].
5907 * Added ^U functionality, clear input line. Patch from cras.
5909 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Mainly small bugfixes on core library. Fixed some debugging
5912 logging and buffer overflow in silclog.c.
5914 * Updated config.sub and config.guess on the distribution tree.
5916 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added command lagging support in server. Client may execute
5919 commands now only once in two seconds.
5921 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Optimized packet reception. MAC computation and checking is now
5924 also more optimized. A lot previously duplicated code is now
5925 used as generic by both client and server.
5927 * Fixed key pair generation in clientutil.c
5929 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added into lib/silccore/silcbufutil.[ch] new function;
5932 silc_buffer_realloc.
5934 * Moved generic packet sending/encryption functions to
5935 lib/silccore/silcpacket.[ch] from client and server. Some
5936 rewriting of the functions.
5938 * Moved all generic packet reception/decryption functions to
5939 lib/silccore/silcpacket.[ch] from client and server. The
5940 packet processing is now much cleaner in both client and server.
5941 These were major changes in both client and server.
5943 * Created many common functions in server to do packet sending.
5944 Previously code were duplicated a lot, this has been removed
5947 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Rewrote major parts of the ID cache system. Don't know
5950 whether it is better now or not but at least the API is more
5953 * Major rewrite on ID cache stuff on client because of the ID
5954 cache API changes. Added idlist.c to client.
5956 * Also major rewrite on ID cache stuff on server as well.
5957 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5958 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5959 in hand, instead they are all put into the ID cache system now.
5960 All server_idlist_* routines uses ID cache now instead of
5961 traversing its own lists (those lists does not exist anymore).
5962 SilcIDList though still exists. Also, SilcXXXEntry's are
5965 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Finally made the SKE implementation compliant to the protocol
5968 specification. All mp integers are now binary encoded as
5969 opposed being HEX encoded.
5971 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5974 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5975 functions: silc_[encode/decode]_pem. Also added function
5976 silc_encode_pem_file to PEM encode with newlines ('\n') for
5979 * SILC public keys are now encoded either PEM or binary. Same
5980 option is for private keys as well. By default private keys
5981 are binary encoded and public keys PEM encoded. Silly HEX
5982 encoding were removed.
5984 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5985 function to create fingerprints.
5987 * Fixed a bug in SHA1; does not change the original data anymore.
5989 * Partly implemented INFO command on client and server side.
5990 Fixed CLEAR command. Changes to SERVER command; show current
5991 server(s) when giving command without arguments. Added
5992 VERSION command to client.
5994 * Added check to server that unregistered connections cannot
5995 execute commands (unless it is specificly allowed).
5997 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Fixed screen refresh.
6001 * Fixed channel joining bug from client. On some circumstances
6002 client tried to join to a channel it had already joined.
6004 * Added public key verification process into client's protocol.c.
6005 The client now verifies the public key from user and saves
6006 it into ~./silc/serverkeys/ directory.
6008 Added into: clientutil.[ch]: silc_client_verify_server_key.
6010 * Changed SKE protocol's silc_ske_initiator_finish function
6011 to accept callback function that verifies the received public
6012 key. Removed old silc_ske_verify_public_key function.
6014 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6017 silc_pkcs_private_key[_data]_set.
6019 * Made the password and public authentication more cleaner in
6020 server's protocol.c.
6022 * Removed historic and obsolete protocol `channel_auth' from
6023 both client and server.
6025 * Removed wrong way of sending command status messages from
6026 server to client in server's command.c. The old way violated
6027 protocol specification.
6029 Changes to silccore/silccommand.[ch]: removed
6030 silc_command_encode_status_payload -> not needed anymore,
6031 changed silc_command_encode_payload_va to accept extra
6032 argument on variable argument list. The argument type must
6033 now be provided to the function. Also, added new function:
6034 silc_command_encode_reply_payload_va which is same as
6035 normal command_encode_payload_va except command status type
6036 is provided as extra argument.
6038 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Added ~./silc directory handling. The directory includes the
6041 public and private keys for the client.
6043 Added silc_client_check_silc_dir, silc_client_create_identifier
6044 and silc_client_load_keys.
6046 * Implemented SILC protocol compliant public key. Added public
6047 and private key saving to and loading from files.
6049 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6050 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6051 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6052 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6053 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6055 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6056 silc_pkcs_load_[public/private]_key.
6058 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Added silc_server_get_route (route.[ch]) to get connection
6061 data for the fastest route for given ID.
6063 * Implemented INVITE command on client and server. The command
6064 were re-defined in the SILC Protocol Specification and the
6065 implementation now complies with the specification.
6067 * Implemented PING command on client and server.
6069 * Implemented NAMES command on client and server. The server side
6070 supports currently only normal server not router server yet.
6071 Some changes to NAMES definition in SILC protocol specification.
6073 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Implemented LEAVE command on client and server.
6077 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6078 again. This change was made to the protocol as well. Server
6079 should not violate the protocol specification anymore.
6081 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6084 was tested. SOCKS4 was not but should work anyway.
