3 * Don't use __restrict in older GCC's. Affected file is
4 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
6 * silc_net_localhost now attempts to reverse lookup the
7 IP/hostname. Affected file lib/silcutil/silcnet.c.
9 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
10 command. It can be used to gain founder privileges at
11 the same time when joining the channel.
13 Defined that the SILC_NOTIFY_TYPE_KICKED send the
14 kicker's client ID as well. Updated protocol specs.
16 Defined that the server must send SILC_COMMAND_IDENTIFY
17 command reply with error status to client who sent
18 private message with invalid client ID.
20 Updated the protocol specification.
22 * Added silc_server_send_command_reply to send any
23 command reply. Affected file silcd/packet_send.[ch].
25 * Added silc_id_payload_encode_data to encode ID payload
26 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
28 * The server now send IDENTIFY command reply with error
29 status if client ID in private message is invalid. Affected
30 file silcd/packet_receive.c.
32 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
34 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
37 * Added libtool support for compiling shared objects in
38 lib/silcsim. Affected file configure.in.pre and
39 lib/silcsim/Makefile.am. Original patch by cras.
41 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Pid file configuration, and server's config file fixes
44 patch by toma. Updated CREDITS file.
46 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
48 * Fixed silc_client_channel_message to not try to decrypt
49 the message twice if it resolved the destination client
50 information. This could cause of dropping one channel
51 message. Affected file lib/silcclient/client_channel.c.
53 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
55 * Added silc_client_run_one into lib/silcclient/silcapi.h and
56 lib/silcclient/client.c. This function is used when the SILC
57 Client is run under some other scheduler, or event loop or
58 main loop. On GUI applications, for example this may be
59 desired to used to run the client under the GUI application's
60 main loop. Typically the GUI application would register an
61 idle task that calls this function multiple times in a second
62 to quickly process the SILC specific data.
64 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
66 * Fixed silc_server_drop() for dropping the supplementary
67 groups as well, this could cause a security hole on some
70 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
72 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

76 to run server on foreground. A patch by debolaz.
77 Affected files silcd/server.c, silcd/silcd.c.
79 * Fixed MOTD to return the MOTD file server name. Affected
82 * Added INFO command reply handling to the Irssi SILC Client.
83 Affected file irssi/src/silc/core/client_ops.c.
85 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
87 * Fixed the silc_idcache_list_* routines to really support
88 the dynamic list. Fixes a crash. Affected file is
89 lib/silccore/silcidcache.c.
91 * Fixed the LIST command reply to really call LIST command's
92 pending callbacks. Affected file silcd/command_reply.c.
94 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
96 * Update conn->local_entry->nickname after giving NICK
97 command. Affected file lib/silcclient/command.c.
99 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
101 * Added the [pid] option to the silcd configuration file
103 Affected files: serverconfig.[ch] and silcd.c
105 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
107 * Save fingerprint in WHOIS command reply in server.
108 Affected file silcd/command_reply.c.
110 * Fixed NICK commands pending callback registration.
111 Affected file lib/silcclient/command.c.
113 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
115 * Use ++server->cmd_ident when sending commands in server,
116 instead of random number. Affected file silcd/command.c.
118 * Fixed GETKEY command reply to call actually GETKEY pending
119 command callbacks. Affected file silcd/command_reply.c.
121 * A bit stricter check for nicknames. Check for same nickname
122 in NICK command also. Affected file silcd/command.c.
124 * Do not call INFO command everytime client ID changes, only
125 during first connecting. Affected file lib/silcclient/client.c.
127 * Set the new nickname only after successful command reply for
128 NICK command is returned by server. Affected file
129 lib/silcclient/command.c.
131 * Remove nicknames from nicklist during server_signoff notify.
132 Should fix /NAMES bit more. The affected file is
133 irssi/src/silc/core/silc-channels.c.
135 * Added `fingerprint' field to the SilcIDListData in the
136 silcd/idlist.h to hold the fingerprint of the client's
139 Send the fingerprint of the client's public key in WHOIS
142 Affected files silcd/command.c, and silcd/idlist.[ch].
144 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
145 create fingerprint from given data.
147 * Show the fingerprint of the client's public key in WHOIS.
148 Affected files irssi/src/module-formats.[ch] and
149 irssi/src/silc/core/client_ops.c.
151 * Format the multiple same nicknames also during JOIN and
152 NICK_CHANGE notifys. Affected file is
153 lib/silcclient/client_notify.c.
155 * Do not print error on screen for invalid private message
156 payload since it can come if someone is sending private
157 messages with wrong key. Affected file
158 lib/silccore/silcprivate.c.
160 * Fixed multiple concurrent /PING crash. Affected file
161 lib/silcclient/command.c.
163 * Changed the wrong ID encoding. All IP addresses must be
164 in MSB first order in encoded format. They were encoded
165 wrong and was in LSB format. Affected files are
166 silcd/serverid.c, lib/silcutil/silcutil.c.
168 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
170 * Call the `connect' client operation through the scheduler
171 in case of error. Affected file lib/silcclient/client.c.
173 * Call the `failure' client operation even if the error
174 occurred locally during a protocol. Affected file is
175 lib/silcclient/protocol.c.
177 * Added support of sending LIST command to router from normal
178 server. This way normal server can get list of all channels
179 in the network too. Fixed the channel list sending in the
180 server too. Affected files are silcd/command.c, and
181 silcd/command_reply.[ch].
183 * Added silc_server_update_channels_by_server and
184 silc_server_remove_channels_by_server. They are used during
185 disconnection of primary router and in backup router protocol.
186 Affected file silcd/server_util.[ch], silcd/server.c and
187 silcd/server_backup.c.
189 * Fixed channel adding to global list in IDENTIFY command
190 reply in server. Affected file silcd/command_reply.c.
192 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
194 * If the incoming packet type is REKEY or REKEY_DONE process
195 that packet always synchronously. Fixes yet another MAC
196 failed error on slow (dialup) connections. Affected file
197 lib/silcclient/client.c and silcd/server.c.
199 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
201 * Call check_version SKE callback for initiator too. Affected
202 file lib/silcske/silcske.c.
204 * Implemented fix for security hole found in the SKE that was
205 fixed in the specification few days back; the initiator's
206 public key is now added to the HASH value computation.
207 Added backwards support for the old way of doing it too, for
208 old clients and old servers. Affected file is
209 lib/silcske/silcske.c.
211 * Enabled mutual authentication by default in SKE. If initiator
212 is not providing mutual authentication the responder will
213 force it. This will provide the proof of posession of the
214 private key for responder. The affected files are
215 lib/silcclient/protocol.c and silcd/protocol.c.
217 * Do not cache anymore the server's public key during SKE.
218 We do mutual authentication so the proof of posession of
219 private key is done, and if the server is authenticated in
220 conn auth protocol with public key we must have the public
221 key already. Affected file silcd/protocol.c.
223 * Added new global debug variable: silc_debug_hexdump. If
224 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
225 file lib/silcutil/silclog.[ch].
227 * Fixed compilation warning due to char * -> const char *.
228 Affected files lib/silcutil/silcnet.h, and
229 lib/silccore/silcauth.[ch].
231 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
233 * Fixed CMODE command when new channel key was created. If
234 the creation failed the old key was removed. Next time giving
235 same command would crash the server since the old key was
236 freed already. Affected file silcd/command.c.
238 * Fixed the silc_server_announce_get_channels to not crash
239 on reconnect. Affected file silcd/server.c.
241 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Added silc_log_set_debug_string function to set a regex
244 string to match for debug output. Only the function names,
245 or filenames matching the given debug string is actually
246 printed. This way it is possible to filter out those debug
247 strings that user is not interested in.
249 Fixed a bug in silc_string_regexify.
251 Affected files lib/silcutil/silclog.[ch], and
252 lib/silcutil/unix/silcunixutil.c.
254 * Changed the -d options in both server and Irssi SILC client
255 to take the debug string as argument. Affected files
256 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
258 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Added silc_hash_babbleprint to create a Bubble Babble
261 Encoded fingerprint. The encoding is developed by Antti
262 Huima (draft-huima-babble-01.txt), and it creates human
263 readable strings out of binary data. Affected file
264 lib/silccrypt/silchash.[ch].
266 * Print the babble print now in addition of fingerprint as well
267 in Irssi SILC client. Affected files are
268 irssi/src/fe-common/silc/module-formats.[ch],
269 irssi/src/fe-common/silc/core/client_ops.c.
271 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
273 * Fixed a security problem found in SKE. The initiator's
274 public key too is now added to the HASH hash value creation
275 which is signed by the responder to create the SIGN value.
276 This will prevent anyone in the middle to lie to the responder
277 about the initiator's public key. If this is done now, the
278 man in the middle will get caught. Updated the protocol
281 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
283 * Better installation directory handling. Configure module
284 paths and other paths automatically to example_silc* files
285 in doc/. A patch by toma.
287 * Fixed compiler warning from MPI library, and from SILC RNG.
290 * Added SILC_SERVER_PID_FILE to define the pid file for server.
291 It can be configured with ./configure. A patch by toma.
293 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
295 * Find correct make to use in prepare-clean. A patch by
296 toma. Affected file prepare-clean.
298 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
300 * Added irssi variables use_auto_addr, auto_bind_ip,
301 auto_bind_port and auto_public_ip.
303 * Changed the interface for silc_client_send_key_agreement
304 in lib/silcclient/silcapi.h
308 irssi/src/silc/core/silc-core.c
310 lib/silcclient/silcapi.h
311 irssi/src/silc/core/silc-channels.c
312 lib/silcclient/client_keyagr.c
315 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
317 * Added silc_pkcs_public_key_compare to compare two
318 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
320 * Check that the client who set the founder mode on the
321 channel is the same client that is giving the founder
322 mode to itself. It is done by comparing the saved public
323 key (it is saved even in the authentication is passphrase).
324 Affected file silcd/command.c.
326 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
328 * Do not process packet for disconnected socket connection.
329 Affected file lib/silccore/silcpacket.c.
331 * Process the DISCONNECT packet through scheduler in the
332 client library. Affected file lib/silcclient/client.c.
334 * Fixed the silc_client_packet_parse to not to increase
335 the packet sequence number if the conn->sock and the
336 current socket connection is not same. This can happen
337 for example during key agreement when the conn includes
338 multiple socket connections (listeners). Affected file
339 lib/silcclient/client.c.
341 * The sender of the file transfer request now provides also
342 the pointer (listener) for the key exchange protocol. If
343 the listener cannot be created then it sends empty key
344 agreement and lets the receiver provide the listener.
346 Added `local_ip' and `local_port' arguments to the
347 silc_client_file_send. If they are provided they are used,
348 if not then it will attempt to find local IP address, if
349 not found or bind fails then the remote client will provide
352 Affected files are lib/silcclient/client_ftp.c and
353 lib/silcclient/silcapi.h.
355 * Extended the FILE SEND command to support defining the
356 local IP and port for key exchange listener. They are
357 optional. Affected file irssi/src/silc/core/silc-servers.c.
359 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
361 * Defined to WHOIS command reply the sending of fingerprint
362 of the client's public key (if the proof of posession of the
363 corresponding private key is verified by the server).
364 Updated to the protocol specification.
366 * Added support of receiving the client's public key's
367 fingerprint in command reply in client library. Affected
368 file is lib/silcclient/command_reply.c, and
369 lib/silcclient/idlist.[ch].
371 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
373 * Do not send over 128 chars long nickname to the server
374 in NICK command. Affected file lib/silcclient/command.c.
376 * Do not send over 256 chars long channel names to the server
377 in JOIN command. Affected file lib/silcclient/command.c.
379 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
381 * Assure that silc_server_close_connection cannot be called
382 twice for same socket context. Affected file is
385 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
387 * Send error message to application if opening file for
388 writing during file transfer fails. Affected file is
389 lib/silcclient/client_ftp.c.
391 Remove all file transfer sessions for a client that we're
392 removing from ID cache.
394 Affected file is lib/silcclient/client_ftp.c.
396 * Fixed silc_net_addr2bin to return correct address. Affected
397 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
399 * Fixed file transfer session removing on signoff notify.
400 Affected file irssi/src/silc/core/silc-servers.c.
402 * Added the SilcClientFileError to be returned in the monitor
403 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
404 Affected file lib/silcclient/silcapi.h.
406 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
408 * Fixed a crash in silc_client_ftp_free_sessions and
409 silc_client_ftp_session_free_client. Affected file
410 lib/silcclient/client_ftp.c.
412 * Added `disabled' field in the SilcChannelEntry in the server
413 to indicate if the server entry is disabled. Affected file
414 silcd/idlist.h, silcd/command[_reply].c.
416 * SILC server adds now /var/run/silcd.pid everytime it is
417 started. Affected file silcd/silcd.c.
419 * Added silc_server_packet_send_clients to send a packet to
420 the provided table of client entries. Affected file
421 silcd/packet_send.[ch].
423 * Fixed a crash in client resolving in client_prvmsg.c in
424 client library. Affected file lib/silcclient/client_prvmsg.c.
426 * Do not actually remove the client directly from ID cache
427 during SERVER_SIGNOFF, but invalidate it. This way we
428 preserve the WHOWAS info for the client. Affected file
431 * Fixed SERVER_SIGNOFF notify handling in the server. The
432 server is now able to process incoming SERVER_SIGNOFF notify
433 for a server that it doesn't even know about. It will remove
434 the clients provided in the notify. Affected file
435 silcd/packet_receive.c.
437 * Check for partial packet in data queue after every packet that
438 was found from the queue. Return and wait for more data if
439 there is partial data in queue. Affected file is
440 lib/silccore/silcpacket.c.
442 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
444 * Added SilcClietFileError enum to indicate error in
445 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
446 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
447 Affected files lib/silcclient/silcapi.h and

450 * Check that newsize in silc_buffer_realloc is larger than
451 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
453 * Added better monitor of file transfers. It now monitors
454 key agreement protocol during the file transfer too. Added
455 error reporting too. Affected files
456 irssi/src/silc/core/silc-servers.c,
457 irssi/src/fe-common/silc/module-formats.[ch].
459 * Wrote a help file for FILE command.
461 * Added silc_rng_global_get_byte_fast to get not-so-secure
462 random data as fast as possible. Random data is read from
463 /dev/urandom if available and from the SILC RNG if not
464 available. It is used in padding generation. Affected file
465 lib/silccrypt/silcrng.[ch].
467 * All packets in client library are now processed synchronously.
468 Optimized packet processing a lot. Affected file
469 lib/silcclient/client.c.
471 * All server connection packets are processing synchronously
472 now in server, to optimize packet processing. Affected file
475 * Include files are installed now only in Toolkit distribution
476 if make install is given. Affected files: all Makefile.am's.
478 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
480 * Assure that silc_client_notify_by_server_resolve does not
481 resolve the client information multiple times. If it cannot
482 be found by the first it cannot be found at all. Affected
483 file lib/silcclient/client_notify.c.
485 * Fixed WHOWAS command reply calling. Affected file
486 lib/silcclient/command_reply.c.
488 * Removed all references to silc_idlist_get_client from the
489 Irssi SILC client since that call is internal call used by
490 the library. The Irssi SILC client will use now client
491 retrieval functions found in silcapi.h.
493 * Fixed a bug in resolving nickname info before sending
494 private message. It used freed memory. Affected file
495 irssi/src/silc/core/silc-servers.c.
497 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
499 * Assure my_channels statistics cannot go negative in server.
500 Affected files silcd/server.c, silcd/server_util.c.
502 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

506 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
508 * Win32 Toolkit changes. Affected files
509 win32/silc.dsw, win32/libsilc/libsilc.def,
510 win32/libsilcclient/libsilc.def,
511 lib/silcutil/silcutil.c, and
512 lib/sftp/sftp_fs_memory.c.
514 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
516 * Added silc_net_localip to return local host's IP address.
517 Affected file lib/silcutil/silcnet.[ch].
519 * If key exchange or rekey protocol is active for a connection
520 parse all packets syncronously since there might be packets
521 in packet queue that we are not able to process without first
522 processing packets before them. Affected file silcd/server,
523 lib/silcclient/client.c.
525 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
526 whether library should continue processing the packet.
527 Affected file lib/silccore/silcpacket.h.
529 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
530 SilcSFTPMonitorData to SFTP server to monitor various
531 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
532 lib/silcsftp/sftp_server.c.
534 * Added silc_file_size to return file size. Affected file
535 lib/silcutil/silcutil.[ch].

539 transmission. Affected file lib/silcclient/client_ftp.c,
540 lib/silccilent/client.[ch].
542 * Added new local command FILE to the Irssi SILC Client.
543 It is used to perform the file transfer. It has subcommands
544 SEND, RECEIVE, SHOW and CLOSE. Affected files
545 irssi/src/silc/core/client_ops.c,
546 irssi/src/silc/core/silc-server.[ch].
548 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Relay the SILC_PACKET_FTP in the server. Affected files
551 silcd/server.c and silcd/packet_receive.c.

562 * Resolve the client info when received private message or
563 channel message for a client which nickname we don't know.
564 Affected files lib/silcclient/client_prvmsg.c and
565 lib/silcclient/client_channel.c.
567 * Do not crash in /KEY if client is not connected. Affected
568 file irssi/src/silc/core/silc-channels.c.
570 * Added SilcClientStatus field to the SilcClientEntry in the
571 lib/silcclient/idlist.h.
573 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
574 is incomplete and is being resolved, it won't be resolved
577 Make sure also that USERS command reply does not resolve
578 twice information. Affected file is
579 lib/silcclient/command_reply.c.
581 Make sure that silc_client_get_clients_by_list does not
582 resolve twice same information.
584 * Check for valid client->id in the silc_server_free_client_data.
585 Affected file silcd/server.c.
587 * Fixed /GETKEY nick@server not to crash if the server entry
588 is not found. Affected file lib/silcclient/command.c.
590 * Fixed the silc_server_check_cmode_rights to check the
591 requested modes correctly. Affected file silcd/command.c.
593 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
595 * Better checks for non-printable chars in nick added.
596 Affected file silcd/command.c.
598 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
600 * Call the silc_server_udpate_servers_by_server in the
601 primary router that comes back online in the backup resuming
602 protocol. Otherwise it routes packets wrong. Affected file
603 silcd/server_util.[ch], silcd/server_backup.c.
605 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
607 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
608 lib/silcutil/silcbuffmt.[ch].
610 * Redefined the SILC packet header to include the padding
611 length. Affected file lib/silccore/silcpacket.[ch].
613 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
614 length for maximum padding up to 128 bytes). Affected
615 file lib/silccore/silcpacket.h.
617 * Removed all backwards support for old 0.5.x MAC thingies.
618 The SILC packet header change makes it impossible to be
619 backwards compatible.
621 * Send the ENDING packet with timeout in the backup resuming
622 protocol. This is to assure that all routers has connected
623 to the primary router. Affected file silcd/server_backup.c.
625 * Changed the RNG to take the first IV from random data. It
626 used to take it from zero actually. Changed the RNG also
627 to use /dev/urandom during session. /dev/random is used
628 in initialization. Affected file lib/silccrypt/silcrng.[ch].
630 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Changed the SILC packet header to have the first two bytes
633 (the packet length) encrypted. Affected files aroung the
634 code tree, lib/silccore/silcpacket.[ch]. Removed the
635 SilcPacketCheckDecrypt callback. It is not needed anymore
636 since the silc_packet_receive_process will determine now
637 whether the packet is normal or special.
639 * Implemented the unidirectional MAC keys. Affected files
640 lib/silcske/silcske.c, silcd/protocol.c and
641 lib/silcclient/protocol.c.
643 * Implemented the packet sequence number to the MAC computation.
644 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
645 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
646 lib/silcclient/protocol.c.
648 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Allow backup router to announce servers. All servers
651 announced by backup router are added to the global list
652 automatically. Update hte server's socket to our primary
653 router also when backup router announces a server.
654 Affected file silcd/packet_receive.c.
656 * Do not update the client->router in the function
657 silc_server_udpate_clients_by_server if the client is on
658 global list. We might fail to find any specific server
659 for locally connected clients and local cell clients. They
660 should still use the `from' and not `to' as client->router.
661 This fixes backup router resuming protocol. Affected file
664 * Decrease channel statistics count only if the channel
665 deletion worked. Affected files are silcd/server.c and
668 * Added silc_server_update_servers_by_server to update origin
669 of all server entries. Used during backup router protocol.
670 Affected files silcd/server_util.[ch], silcd/server.c. and
671 silcd/backup_router.c.
673 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
674 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
675 silc_hmac_get_hash and silc_hmac_get_name. Affected file
676 lib/silccrypt/silchmac.c.
678 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
680 * Assure that router cannot reroute the same channel message
681 to the sender. Affected file silcd/packet_receive.c.
683 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
685 * Made better checks that the channel message is not sent
686 to the router it came from. Affected file is
687 silcd/packet_send.c. Fixed memory leak too.
689 * Announce informations for incoming router connection, but
690 only after checking if it is replaced by backup router.
691 Affected file silcd/packet_receive.c.
693 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Fixed the backup resuming protocol to work in multiple
696 router environment. Affected file silcd/server_backup.c.
698 * Route packet only to one router in the function
699 silc_server_packet_send_to_channel. Affected file is
702 * Fixed silc_server_send_notify_dest to set the broadcast
703 flag. Fixed the silc_server_send_notify_topic to actually
704 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
705 Affected file silcd/packet_send.c.
707 * Changed the SFTP Filesystem interface. Changed the
708 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
709 the filesystem operation function. The SilcSFTPFilesystem
710 is now a context that is allocated by all filesystem allocation
711 functions and it already includes the operations structure
712 and filesystem specific context. It is given as argument
713 now to the silc_sftp_server_start. This made the interface
714 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
715 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
717 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
719 * Changed the backup router adding and getting interfaces
720 in the server. The router that will be replaced by the
721 specified backup router is now sent as argument. Affected
722 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
725 * Added silc_net_addr2bin_ne to return the binary form of
726 the IP address in network byte order. Affected files
727 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
729 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
731 * Check for existing server ID in silc_server_new_server
732 and in silc_server_connect_to_router_final and remove the
733 old entry if it exists. Affected file silcd/packet_receive.c,
736 * Send the channel message always to only one router, either
737 in upstream or downstream. Affected file is
740 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
742 * Wrote the definition of the backup resuming protocol to the
743 protocol specification.
745 * Removed one redundant channel key generation from normal
746 server during joining procedure. Removed one redundant
747 channel key sending from server to router during joining
748 procedure. Affected file silcd/command.c.
750 * Made minor bugfixes to the backup router resuming protocol.
751 Affected file silcd/server_backup.c, server.c.
753 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Added --disable-asm configuration option. Affected files
756 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
759 * Implemented the backup resuming protocol that is used to
760 resume the primary router position in the cell after the
761 primary router comes back online. Affected files
762 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
763 and silcd/server_util.[ch].
765 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
767 * Sleep two (2) seconds after sending QUIT command to server.
768 Affected file lib/silcclient/command.c.
770 * Assure that if outgoing data buffer is pending do not force
771 send any data. Affected file silcd/packet_send.c.
773 * Assure that if outgoing data buffer is pending do not force
774 send any data. Affected file lib/silcclient/client.c.
776 * Implemented the backup router support when the primary router
777 goes down. The servers and routers can now use the backup
778 router as new primary router without loosing connectivity.
780 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
783 in the server to indicate disabled entry. All data read
784 from the connection will be ignored and no data is sent
785 for entry that is disabled. Affected files are
786 silcd/idlist.h, silcd/server.c.
788 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Created SFTP client and server test programs in the
791 lib/silcsftp/tests directory.
793 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
795 * Implemented memory filesystem (virtual filesystem) for
796 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
799 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Implemented the SFTP (SSH File Transfer Protocol) to the
802 lib/silcsftp. It includes SFTP client and SFTP server
805 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Moved lib/silccore/silcprotocol.[ch] to the
808 lib/silcutil library.
810 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
811 take variable argument list pointer as argument. Affected
812 file lib/silcutil/silcbuffmt.[ch].
814 * Added silc_buffer_set function that is used to set data
815 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
816 Affected file lib/silcutil/silcbuffer.h.
818 * Changed various routines in the core library to use the new
819 silc_buffer_set instead of allocating new buffer only for
822 * Added 64-bit value formatting and unformatting support to the
823 silc_buffer_[un]format routines. Affected file is
824 lib/silcutil/silcbuffmt.[ch].
826 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
827 to includes/bitmove.h.
829 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed channel user mode saving in client library. Affected
832 file lib/silcclient/command[_reply].c.
834 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Defined the file transfer to the SILC Protocol. Added
837 new packet type SILC_PACKET_FTP and defined File Transfer
838 Payload. The mandatory file transfer protocol is SFTP
839 (SSH File Transfer Protocol). Affected file in addition
840 of the internet draft is lib/silccore/silcpacket.h.
842 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
843 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
844 is used as part of backup router protocol when the primary
845 router of the cell is back online and wishes to resume
846 the position as primary router.
848 * Redefined the MAC generation keys in the protocol. The
849 same key is not used anymore in both direction. Both
850 direction will now use different keys for sending and
851 receiving. This fixes a potential security flaw. This
852 change causes incompatibilities in the protocol.
854 * Redefined also the MAC computation from the packet.
855 An packet sequence number is now added to the MAC
856 computation. This prevents possible replay attacks against
857 the protocol. This change too causes incompatibilities
860 Added `sequence' field to the SilcPacketContext to hold
861 the current sequence number for the packet.
863 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Added `created' field to the SilcIDListData in the file
866 silcd/idlist.h to indicate the time when the entry was
869 * Added `created' field to the SilcChannelEntry too. Affected
872 * Added `creation_time' aguments to all the announcement functions
873 in the server. If it is provided then only the entries that
874 was created after the provided time frame are actually
875 announced. Affected file silcd/server.[ch].
877 * The protocol says that the Channel ID's IP address must be
878 based on the router's IP address. Added check for this in
879 the silc_server_new_channel when processing incoming New Channel
880 Payload. Affected file silcd/packet_receive.c.
882 * Print out the correct version with --version in SILC client.
883 Affected file irssi/src/silc/core/silc-core.c.
885 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
887 * Fixed WHOWAS command to check for completnes of the client
888 entry always, not just when the command is coming from client.
889 Affected file silcd/command.c.
891 * Added new function silc_server_packet_queue_purge to purge the
892 outgoing data queue to the network. After the function returns
893 it is guaranteed that the outgoing packet queue is empty.
894 Affected file silcd/packet_send.[ch].
896 * Purge the outgoing packet queue in the rekey protocol's final
897 callback to assure that all rekey packets go to the network
898 before quitting the protocol. Affected file silcd/server.c.
900 * Added silc_client_packet_queue_parse as similar function as
901 in server to the client library. The affected file is
902 lib/silcclient/client.c.
904 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Splitted silcd/server.c and created silcd/server_util.[ch]
907 for utility functions.
909 * Added new socket flag SILC_SF_DISABLED to indicate that the
910 connection is open but nothing can be sent to or received from
911 the connection. Affected file lib/silcutil/silsockconn.[ch].
912 The checking for disabled socket is checked in the low level
913 silc_socket_write and silc_socket_read functions.
915 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Allow only nicknames and channel names that fits into the
918 7-bit unsigned char ASCII set. Affected file silcd/command.c.
920 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
922 * When processing JOIN command reply in server check that if
923 the channel exists in our global list we'll move it the local
924 list. Affected file silcd/command_reply.c.
926 * Fixed the check whether client is joined on the channel already
927 in JOIN command. Affected file lib/silcclient/command.c.
929 * Fixed the JOIN command reply to check whether the channel
930 already exists. Affected file lib/silcclient/command_reply.c.
932 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Added silc_ske_status_string to map the SKE error numbers
935 to readable strings. The affected files are
936 lib/silcske/silcske[_status].[ch].
938 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Do not show the private channels on the WHOIS channel list
941 as it is not allowed by the protocol. The affected file is
944 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Assure that the packet length digged from the actual packet
947 is something sensible in the silc_packet_decrypt_rest_special
948 in lib/silccrypt/silcpacket.c.
950 * Free and NULL the allocated pointer in silc_hmac_alloc if
951 the HMAC allocation fails. The affected file is
952 lib/silccrypt/silchmac.c.
954 * Print the selected security properties to the log files in
955 the server. Affected file silcd/protocol.c.
957 * Add SKE's reference counter even if calling the completion
958 callback manually. Otherwise it goes negative, although it
959 does not cause any problems. The affected file is
960 lib/silcske/silcske.c.
962 * Remove the client entry with short timeout after giving the
963 KILL command. Affected file lib/silcclient/command.c.
965 * Fixed to send error reply in WHOIS and IDENTIFY commands in
966 case all found clients are already disconnected (WHOWAS would
967 found them) in the server. Affected file silcd/command.c.
969 * Update the last_receive (time of last data received) to be
970 updated only when received private or channel message so that
971 the idle time showed in WHOIS makes more sense.
973 * Added boolean field `valid' in to the SilcClientEntry in the
974 client library to indicate whether the entry is valid or not.
975 This fixes the nickname change bug on channel when changing
976 the nickname to be same than the old (like nick to Nick) the
977 nickname formatter doesn't set the new nick anymore to Nick@host.
978 Affected file lib/silcclient/idlist.[ch].
980 * Now actually fixed the nickname changing on disconnection.
981 Added new function silc_change_nick to the Irssi SILC Client.
982 Affected file irssi/src/silc/core/client_ops.c,
983 irssi/src/silc/core/silc-nicklist.[ch].
985 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
987 * Check that the public key exists in the GETKEY command before
988 trying to encode it. Affected file silcd/command.c.
990 * Print some notifications on received public keys with GETKEY
991 command in the Irssi SILC Client. Affected files are
992 irssi/src/fe-common/silc/module-formats.[ch],
993 irssi/src/silc/core/client_ops.c.
995 * Use IDENTIFY command to resolve the server information in the
996 GETKEY command instead of INFO command. Affected file
997 lib/silcclient/command.c.
999 * All command reply functions in the client library now calls
1000 the pending command reply callbacks even if an error has
1001 occurred. The server has done this a long time and now it was
1002 time to move the client library to this as well. Now all
1003 errors can be delivered back to the pending command reply
1004 callbacks if necessary. Affected files are
1005 lib/silcclient/command[_reply].[ch].
1007 * Change the nickname on disconnection back to the username
1008 because in reconnect the server will enforce it to it anyway.
1009 Affected file irssi/src/silc/core/silc-servers.c.
1011 * Fixed a config file parsing bug in the Irssi SILC client.
1012 Affected file irssi/src/silc/core/clientconfig.c.
1014 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * When printing the channel mode on JOIN, verify that the
1017 channel key and channel's HMAC are valid. Affected file
1018 irssi/src/silc/core/client_ops.c.
1020 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1023 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1024 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1026 * Removed channel key rekey task deleting from the function
1027 silc_server_save_channel_key. Affected file silcd/server.c.
1028 Added explicit timeout task context instead that is used to
1029 delete the task if we are registering a new task before the
1030 new task has elapsed.
1032 * When channel key rekey occurs the client library now saves
1033 the old channel key for a short period of time (10 seconds) and
1034 is able to use it in case some is still sending channel
1035 messages encrypted with the old key after the rekey. Affected
1036 file lib/silcclient/[idlist.h|client_channel.c].
1038 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Added check to the silc_server_new_id_real to not accept
1041 new ID if it is the sender's own ID. Affected file is
1042 silcd/packet_receive.c.
1044 * Assure that we do not announce ourself or the one we've
1045 sending our announcements when we're router and are announcing
1046 servers to our primary router. Affected file silcd/server.c.
1048 * Fixed silc_server_command_identify_check_client to assemble
1049 correct WHOIS packet. It send corrupted WHOIS packet and
1050 caused problem with router to router connections. Affected
1051 file silcd/command.c.
1053 Fixed also silc_server_command_whois_check the same way
1054 as for the IDENTIFY command.
1056 * Added new SilcIDListStatus to the server in the SilcIDListData
1057 structure. The status now includes the current status of
1058 the entry (like registered, resolved etc.). Affected file
1059 silcd/idlist.[ch]. Defined a bunch of different status types
1060 as well. This replaced the old boolean registered field as well.
1062 Added resolve_cmd_ident field to the SilcClientEntry structure
1063 too so that if the entry is for example being resolved so
1064 another command may attach to the same pending command reply
1065 without requiring to resolve the same entry again. This concept
1066 should optimize the WHOIS and the IDENTIFY resolving under
1067 heavy load by taking away unnecessary resolving for entries
1068 that are being resolved already.
1070 Added support for adding multiple pending commands for one
1071 command idenfier. Affected file silcd/command[_reply].[ch].
1073 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1074 before deleting the data. Otherwise the hash table will have
1075 freed data in comparison functions. Affected file is
1076 silcd/command_reply.c.
1078 * Fixed silc_idlist_replace_client_id to add the new entry to
1079 the cache with NULL nickname. Otherwise there will be invalid
1080 memory as the nickname after the nickname is freed. Affected
1081 file silcd/packet_receive.c.
1083 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1084 saved into wrong slots because the previous number of entries
1085 was not taken into account. Affected file silcd/idlist.c.
1086 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1088 * If we are router and we receive JOIN notify to a channel that
1089 does not have any users then notified client is marked as the
1090 channel founder, as it is it. The affected file is
1091 silcd/packet_receive.c
1093 * Added to the extended hash table API's table_del_*ext functions
1094 the destructor as argument too, so that the caller can decide
1095 which destructor to use or whether to use destructor at all.
1096 Affected file lib/silcutil/silchashtable.[ch].
1098 * Fixed ID Cache purging. It actually deleted the entries from
1099 the hash table after the data was freed. The hash table ended
1100 up comparing freed memory. The affected file is
1101 lib/silccore/silcidcache.c.
1103 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Fixed Irssi SILC client's KILL command's HELP syntax.
1107 * The USERS command now resolves the detailed user information
1108 if the userinfo field is missing. Affected file is
1109 lib/silcclient/command_reply.c.
1111 * Do not print error in silc_file_read if the read file does
1112 not exist. Just silently return NULL. Affected file is
1113 lib/silcutil/silcutil.c.
1115 * Fixed the silc_log_output to not wine about NULL filename
1116 and to not create some bogus " " filename. Affected file is
1117 lib/silcutil/silclog.c.
1119 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1121 * Fixed various printing bugs on the user interface in the
1122 Irssi SILC Client. Minor changes that were forgotten from
1125 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Fixed the configure.in.pre and the compilation and distribution
1128 environment to support the new autoconf 2.52. That version is
1129 now required to compile the CVS trunk.
1131 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1133 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1134 to generally parse user@fqdn format strings. Affected file
1135 lib/silcutil/silcutil.c.
1137 * Added nickname_format and nickname_force_format fields to the
1138 SilcClientParams structure. The first one defines the format
1139 for the nicknames that the library will enforce if the receives
1140 multiple same nicknames. The second one is boolean value and
1141 can be used to force the library to always enforce the format
1142 to the nicknames regardles whether there are multiple nicknames
1143 or not. This configurable formatting was employed to flexibly
1144 support accessing multiple nicknames from the user interface.
1145 The userinterface can now set the nicknames to what ever format
1146 they prefer. Affected file lib/silcclient/silcapi.h.
1148 Added function silc_client_nickname_format to the file
1149 lib/silcclient/idlist.c. It performs the nickname formatting.
1151 Added new field `hostname´ to the SilcClientEntry context.
1152 It holds the hostname of the client. Affected file is
1153 lib/silcclient/idlist.h.
1155 * Irssi SILC Client sets the nicknames in nick@hostn format.
1156 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1157 irssi/src/silc/core/silc-core.c.
1159 The WHOIS printing now also shows both the real nickname and
1160 the formatted nickname so that user knows how to access the
1161 user if there are multiple same nicknames cached. Affected
1162 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1163 printing formatting too to take the hostname now as a separate
1164 argument. The Affected file is
1165 irssi/src/fe-common/silc/modules-formats.[ch].
1167 * Changed the silc_client_get_clients_local to accept the formatted
1168 nickname as argument. It accepts the real nickname too but the
1169 formatted nickname can be used to find the true entry from
1170 multiple entries. Affected file lib/silcclient/silcapi.h and
1171 lib/silcclient/idlist.c.
1173 * Added nickname_format_parse field to the SilcClientParams.
1174 It is a callback function provided by the application to parse
1175 the nickname out of the formatted nickname string. The library
1176 calls it to get the nickname from the formatted string. Since
1177 the application generally knows better the format of the nickname
1178 string it parses it instead of the library, even though library
1179 encodes the formatted string. If the callback function is not
1180 provided then the library will use the string as is. The
1181 affected file is lib/silcclient/silcapi.h.
1183 * All the nickname strings passed to the client library in
1184 commands are now expected to be formatted nickname strings.
1185 If the command does not support the formatted nickname string
1186 it will assume that the sent string is the actual nickname.
1187 Affected file lib/silcclient/command.c.
1189 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Added public key authentication support to OPER and SILCOPER
1192 commands in the client library. Affected file is
1193 lib/silcclient/command.c.
1195 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Changed the get_auth_methdod client operation to be asynchronous.
1198 It can be async if the application resolves the authentication
1199 method from the server during the negotiation. Added new
1200 SilcGetAuthMeth completion callback that the application will
1201 call after resolving the authentication method.
1203 Added function silc_client_request_authentication_method that
1204 the application can use to resolve the authentication method
1205 from the server. Added also SilcConnectionAuthRequest callback
1206 that the library will call after the server has replied. The
1207 application can call this function if it does not know the
1208 current authentication method.
1210 Affected files are lib/silcclient/client.c and
1211 lib/silcclient/silcapi.h.
1213 * The Irssi SILC client now automatically resolves the authentication
1214 method incase any configuration information is not present (and
1215 currently there never is). The affected file is
1216 irssi/src/silc/core/client_ops.c.
1218 * Fixed public key authentication from the client library.
1219 Affected file lib/silcclient/protocol.c. Changed also the
1220 protocol specification about the public key authentication in
1221 the connection authentication protocol. The actual data to be
1222 signed is now computed with a hash function before signing.
1224 * Fixed the public key authentication from the server as well.
1225 Affected file silcd/protocol.c.
1227 * Removed the mlock()'s from the memory allocation routines.
1228 Affected file lib/silcutil/silcmemory.c. The ./configure does
1229 not check anymore for the mlock(). Affected file is
1232 * Fixed USERS command in server to allow the execution of the
1233 command for private and secret channels if the client sending
1234 the command is on the channel. Affected file silcd/command.c.
1236 * Fixed silc_client_get_clients_local to return the clients
1237 count correctly. It could return wrong value. Affected file
1238 lib/silcclient/idlist.c.
1240 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1242 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1243 types. The assembler optimizations seemed not to like 64-bit
1244 data types. The assmebler optimizations thus are now enabled
1245 also for BSD systems as opposed to only enable them for Linux.
1247 * Do not check for threads at all on BSD systems. Affected
1248 file configure.in.pre.
1250 * Removed -n and -h options from the Irssi SILC Client since
1251 they are not used in silc.
1253 * Fixed the prime generation to assure that the first digit
1254 of the generated random number is not zero since our conversion
1255 routines does not like number strings that starts with zero
1256 digit. If zero digit is seen the random number is regenerated.
1257 This caused some corrupted RSA keys when the zero first digit
1258 was met. Affected file lib/silcmath/silcprimegen.c.
1260 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1262 * Fixed WIN32 configuration in the ./configure script.
1263 Fixed to include xti.h on environments that has it.
1264 Patches by Carsten Ilchmann and andrew.
1266 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1268 * Changed the silc_id_create_client_id to be collision
1269 resistant. It is now assured that there cannot be created
1270 two same client ID's. I suspect that some weird bugs in
1271 the server were actually caused by duplicate Client IDs.
1272 Affected file silcd/serverid.[ch]. A router receiving
1273 new ID now also assures and informs the sending server
1274 if the ID caused collision.
1276 * Changed the silc_id_create_channel_id to also assure that
1277 there are no collisions.
1279 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1281 * Statement about ignoring the Mutual Authentication flag when
1282 performing rekey with PFS was a bit misleading. It is ignored
1283 if it was set in the initial negotiation, it cannot be even
1284 set in the rekey. Fixed in the ke-auth draft. Started the
1285 new versions of the protocol drafts in the doc/.
1287 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Fixed a bug in silc_client_command_identify_save when saving
1290 new channel information. The channel name was no duplicated
1291 and caused crash on exit. Affected file is
1292 lib/silcclient/command_reply.c.
1294 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Fixed the getkey command handling in the server. Send just
1297 empty OK reply to the sender if the key could not be fetched
1298 (but everything else was ok, like the key just was not available).
1299 Changed the public key parameter to optional in the protocol
1300 specs so that empty OK reply can be sent. Affected file
1303 Added a message to Irssi SILC client to tell to user if the
1304 server did not return a public key.
1306 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * Fixed a channel key regeneration bug. It registered new
1309 timeout tasks exponentially until all system resources were
1310 used. Affected file silcd/server.c.
1312 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * Added the SILC Document generator to the scripts/silcdoc.
1315 It can be used to generate the Toolkit Reference Manual out
1316 of the source tree. Internally it will also use the RoboDoc
1317 generator now imported in util/robodoc.
1319 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Added couple of return's in rekey protocol if error orccurred
1322 during the protocol. The execution must be terminated.
1323 Affected file silcd/protocol.c. Also, terminate the protocol
1324 always with timeout.
1326 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * The client's Client ID was created initally from the wrong
1329 nickname (it could have been in format nick@host) in the
1330 silc_server_new_client. Affected file silcd/packet_receive.c
1332 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Added some SILC_LOG_ERROR's to various error conditions
1335 if client could not be added to ID cache. Affected files
1336 silcd/packet_receive.c and silcd/server.c.
1338 * When client's sock->user_data is freed, NULL also the
1339 client->router and client->connection pointers. Added check
1340 for these pointers being NULL to various places around the
1341 code. Affected file silcd/server.c.
1343 * Added client->data.registered == TRUE checks to various
1344 places around the code to assure that unregistered client's
1345 are not handled when it is not allowed. Affected file
1348 * Added `bool registered' fields to all
1349 silc_idlist_[server|client]_get_* routines to indicate whether
1350 the fetched client needs to be registered or not. Affected
1351 file silcd/idlist.[ch].
1353 * Add your own entry as registered to the ID cache in the
1354 server. Affected file server.c.
1356 * Fixed a bug in silc_server_new_server. The SilcServer was
1357 set as the new server's context instead of SilcServerEntry.
1358 This naturally caused some weird bugs.
1360 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Do not delete the channel rekey task when adding it
1363 for in silc_server_create_channel_key.
1365 * Changed the silc_server_create_channel_key to return
1366 TRUE or FALSE to indicate the success of the channel key
1369 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Fixed MSVC++ project files and added missing files to
1372 Makefiles under win32/.
1374 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Do not add TCP_NODELAY flag if the operating system
1377 does not have it defined. Affected files are
1378 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1380 * Fixed buffer overflow from Irssi SILC Client. Affected
1381 file irssi/src/fe-common/core/themes.c.
1383 * Fixed double free in client library in the file
1384 lib/silcclient/client.c when disconnecting from server.
1386 * Applied double free patch from cras to Irssi SILC client.
1387 Affected files irssi/src/core/[modules/expandos].c
1389 * Fixed the disconnection handling to Irssi SILC Client.
1390 The application must call silc_client_close_connection
1391 in ops->connect client operation in case of failure of
1392 the connection. Affected file is
1393 irssi/src/silc/core/client_ops.c.
1395 * Do not set sock->protocol to NULL in the function
1396 silc_client_close_connection after executing the protocol's
1397 final callback since the sock might not be valid anymore.
1398 Affected file lib/silcclient/client.c.
1400 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1402 * Do not enable SILC_THREADS if the linking with libpthread
1403 did not happen. Affected file configure.in.pre.
1405 * Added notion to protocol specification that server must
1406 verify the sent authentication payload with CMODE when
1407 setting the channel founder key. Implemented it to the
1408 server. Affected file silcd/command.c.
1410 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Added _EXTRA_DIST SILC distribution variable to the
1413 distributions file. It is used to conditionally add extra
1414 files or directories to the specific distribution. Affected
1415 files ./prepare, Makefile.am.pre and distributions.
1417 Removed the `_' from the start of the distribution names.
1420 * Added README.WIN32 for instructions to compile the Toolkit
1423 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Fixed a double free in disconnection in the server. Affected
1426 file is silcd/server.c.
1428 * Fixed the lib/silcske/groups.c to work now also with GMP
1429 MP library. The string conversion did not work when using
1430 specific base and the base is indicated in the string as well.
1432 * Created win32/ directory which now includes MSVC++ specific
1433 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1434 It will appear only in the toolkit distribution
1436 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Changed the key material distribution function in case when
1439 the hash output is too short. The data is now concatenated
1440 a bit differently than it used to. Made the change to the
1441 SKE protocol specification.
1443 * Added better GMP detection to configure.in.pre. A patch
1446 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Fixed a minor bug in SKE that might cause some problem on
1449 some platforms. Affected file lib/silcske/silcske.c.
1451 * Added the cookie checking for initiator in the SKE. It checks
1452 that the responder returns the sent cookie unmodified. The
1453 affected file is lib/silcske/silcske.c. Added new SKE
1454 error type INVALID_COOKIE that can be sent during the
1455 negotiation. Fixed some memory leaks as well.
1457 * Added the "invalid cookie" error message to Irssi SILC client's
1460 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Added `task_max' field to the SilcClientParams to indicate
1463 the maximum tasks the scheduler can handle. If set to zero,
1464 default values are used. Affected file lib/silcclient/silcapi.h.
1466 * Fixed memory leaks in silc_client_close_connection. Affected
1467 file lib/silcclient/client.c.
1469 * Added silc_client_del_client_entry to client library to free
1470 all memory of given client entry. Affected file is
1471 lib/silcclient/idlist.[ch].
1473 * Added new functions silc_client_del_channel and
1474 silc_client_del_server to delete channel and server entries.
1475 Affected file lib/silcclient/[silcapi.h/idlist.c].
1477 * Removed silc_client_del_client_by_id from silcapi.h.
1479 * Fixed the INFO command to return the server's own info
1480 correctly when querying by Server ID. Affected file is
1483 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1485 * Removed the non-blocking settings in WIN32 code in the
1486 silc_sock_[read/write] and added SleepEx instead. Affected
1487 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1488 of input data is now checked with FIONREAD and ioctlsocket.
1490 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Call silc_schedule_task_del_by_context in the
1493 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1494 Affected file lib/silccore/silcprotocol.c.
1496 * Call silc_protocol_cancel for active protocols in the
1497 silc_server_close_connection if the funtion
1498 silc_server_free_sock_user_data has not been called.
1499 Affected file silcd/server.c.
1501 * Generic tasks cannot be deleted using the del_by_fd
1502 task deleting function since generic tasks does not match
1503 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1505 * Added a notion to SILCOPER help file that the SILCOPER works
1506 only on router server, not on normal server.
1508 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Added for WIN32 support for the new scheduler as well.
1511 Affected file lib/silcutil/win32/silcwin32schedule.c.
1513 * Fixed the SHA1 implementation to work on various platforms.
1515 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1518 API. It is part of the scheduler now. Everything else is
1519 as previously but some functions has changed their names.
1520 Checkout the lib/silcutil/silcschedule.h for the interface.
1521 Updated all applications to use the new interface. Affected
1522 files are lib/silcutil/silcschedule.[ch].
1524 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Found a bug in the SKE implementation. The HASH value,
1527 specified by the protocol, was not computed correctly. The
1528 public key of the responder was not added to the computation
1529 even though it is mandatory. Affected file lib/silcske/silcske.c.
1530 This unfortunately causes incompatibilities with older
1531 clients and servers.
1533 * Added WIN32 specific network init and uninit functions:
1534 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1535 the Winsock2. Affected file lib/silcutil/silcnet.h and
1536 lib/silcutil/win32/silcwin32net.c.
1538 * Set the socket always to nonblocking mode on WIN32 after
1539 reading data or writing data. Affected file is
1540 lib/silcutil/win32/silcwin32sockconn.c.
1542 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Fixed various compilation problems under WIN32. Affected
1545 files lib/silcutil/win32/silcwin32thread.c and
1546 lib/silcutil/win32/silcwin32schedule.c.
1548 * Removed all _internal.h #includes from public header
1549 files. Internal headers must never be included from
1552 Removed also the lib/silcske/payload_internal.h file.
1554 * All include files that may be needed (public and some others
1555 included by the public headers) by application developers are
1556 now copied to the ./includes directory. It does not copy any
1557 internal headers. Affected file Makefile.defines.pre and all
1558 Makefile.am's under lib/ and subdirs.
1560 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Do not change the ~/.silc directory's permissions automatically.
1563 Affected file irssi/src/silc/core/clientutil.c.
1565 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Do not cancel the protocol in silc_server_close_connection
1568 it might cause recursion. Now cancelled in the function
1569 silc_server_free_sock_user_data. Affected file silcd/server.c.
1571 * Fixed the silc_server_remove_clients_by_server to regenerate
1572 the channel keys correctly finally. Added also new function
1573 silc_server_remove_clients_channels to actually do it.
1574 Affected file silcd/server.c.
1576 * Fixed the silc_server_new_channel to not crash by giving
1577 wrong router to the new channel. Affected file is
1578 silcd/packet_receive.c.
1580 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1583 which is given as argument to the silc_client_alloc now.
1584 It can be used to configure the client and set various parameters
1585 that affect the function of the client.
1587 * The USERS command in server did not check whether the channel
1588 is private or secret. Affected file silcd/command.c.
1590 * Added new argument to the USERS command in protocol specification.
1591 The USERS command now can take the channel name as argument
1592 as well. Added support for this in client and server and
1593 updated the protocol specs.
1595 * Completed the GETKEY command in client. It can be now used
1596 to fetch also servers public key not only some clients.
1597 Affected files lib/silcclient/command[_reply].c.
1599 * Added silc_client_get_server to return server entry by the
1600 server name. Affected files lib/silcclient/silcapi.h and
1603 * Redefined the IDENTIFY command in protocol specification to be
1604 more generic. It now can be used to query information about
1605 any entity in the SILC Network, including clients, servers and
1606 channels. The query may be based either the entity's name
1607 or the ID. Added support for this in both client and server.
1609 Affected files silcd/command.c and lib/silcclient/command.c
1610 and command_reply.c.
1612 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1613 the _from_client and _from_server functions. Affected file
1616 * Added silc_client_get_channel_by_id_resolve to the file
1617 lib/silcclient/silcapi.h to resolve channel information by
1618 its ID. Added also silc_client_get_channel_by_id that
1619 does not resolve it from the server.
1621 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Added SilcServerEntry context into the client library
1624 to represent one server. The INFO command now allocates
1625 these to save the resolved server info. For now on the
1626 client library will also keep information about servers,
1627 connected and resolved with INFO.
1629 The INFO command now allocates the SilcServerEntry context
1630 and saves the server info there. The COMMAND_REPLY in
1631 the INFO now returns the parameters to application in
1632 same order as defined in the protocol specification.
1634 The entries are cached in the client->server_cache.
1636 * The INFO command is now issued after received the Client ID
1637 from the server. Affected file lib/silcclient/client.c.
1639 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1640 to the application as the mode changer might be server.
1641 It is guaranteed that NULL is not returned anymore to the
1642 application. Affected file lib/silcclient/client_notify.c.
1644 The ID Type is now also passed to the application so that
1645 it can check whether the returned entry is SilcClientEntry
1648 Added new function silc_client_get_server_by_id to return
1649 the server entry by ID. Affected files are the
1650 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1652 * Do not create the channel in the Irssi SILC Client when issuing
1653 the JOIN command but when received the sucessful JOIN command
1654 reply. Otherwise the channel might get created even though we
1655 could not join it. The Affected file is
1656 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1658 * Fixed a channel joining bug in router. The router must also
1659 check the channel modes, invite and ban lists etc. when serving
1660 the JOIN command sent by normal server. Affected file is
1661 silcd/command.c. The router now resolves the client's
1662 information from the server who sent the JOIN command if it
1663 does not know it, and processes the JOIN command only after
1666 * Changed the SilcCommandCb to take new argument; void *context2.
1667 Affected file lib/silccore/silccommand.h
1669 The second argument in the command callbacks in the server now
1670 includes the SilcServerCommandReplyContext if the command was
1671 called as pending command callback from the command reply.
1672 Otherwise it is NULL. When called as pending the status of the
1673 command reply will be checked and if it was erronous the
1674 error will be sent to the original sender of the command.
1675 This way the client always receives the error messages even
1676 though the server was actually the one who received the error
1677 when it resent the command to router, for example. Affected
1678 files silcd/command[_reply].[ch].
1680 * Fixed sending WHOWAS command's error message to client if
1681 the requested client could not be found. It was missing.
1684 * Changed the CMODE and CUMODE commands reply arguments in the
1685 protocol specification. The Channel ID is now sent in both
1686 of the commands to identify the channel. Implemented this
1687 new feature to the client and server. Affected files
1688 lib/silcclient/command_reply.c and silcd/command.c.
1690 * Made better checks for invite and ban lists in the JOIN
1691 command in server. Affected file silcd/command.c.
1693 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * The server now performs the incoming host IP/DNS lookup
1696 using the silc_socket_host_lookup and thus does not block
1697 the server anymore. Affected file silcd/server.c.
1699 * Completed the multi-thread support for SILC Scheduler in
1700 the lib/silcutil/silcschedule.c.
1702 * Fixed the configure.in.pre to detect the pthread correctly
1705 * Fixed a deadlock in silc_task_queue_wakeup in the file
1706 lib/silcutil/silctask.c.
1708 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Added new function silc_schedule_wakeup that is used in
1711 multi-threaded environment to wakeup the main thread's
1712 schduler. It needs to be used when a thread adds a new task
1713 or removes a task from task queues. After waking up, the
1714 scheduler will detect the task queue changes. If threads
1715 support is not compiled in this function has no effect.
1716 Implemented the wakeup mechanism to both Unix and WIN32
1717 systems. Affected files are lib/silcutil/silcschedule.[ch],
1718 lib/silcutil/unix/silcunixschedule.c and the
1719 lib/silcutil/win32/silcwin32schedule.c.
1721 * Added new function silc_task_queue_wakeup to wakeup the
1722 scheduler by the specified task queue. Affected file
1723 lib/silcutil/silctask.[ch].
1725 * The silc_socket_host_lookup_start now wakes up the scheduler
1726 after adding the timeout task. Affected file is
1727 lib/silcutil/silcsockconn.c.
1729 * The silc_socket_host_lookup is synchronous now if the threads
1730 support is not compiled in. However, the callback is still
1731 called asyncronously through the scheduler, anyway. Affected
1732 file lib/silcutil/silcsockconn.c.
1734 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Added new function silc_socket_host_lookup to perform
1737 asynchronous IP and FQDN lookups for the socket connection.
1738 Affected files lib/silcutil/silcsockconn.[ch].
1740 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1743 that may or may not compile the mutex support in.
1745 Changed the silc_mutex_alloc interface. It allocates the
1746 mutex now to the sent pointer and returns TRUE or FALSE.
1748 Affected file lib/silcutil/silcmutex.h.
1750 * Wrote the SILC Task Queue interface to support multi-threads.
1751 Affected file lib/silcutil/silctask.[ch].
1753 * Wrote the SILC Scheduler to support multi-threads. Affected
1754 file lib/silcutil/silcschedule.c.
1756 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1759 in lib/silcutil/win32/.
1761 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Defined SILC Mutex API and SILC Thread API and implemented
1764 them for Unix. Affected files are
1765 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1766 lib/silcutil/unix/silcunixmutex.c and
1767 lib/silcutil/unix/silcunixthread.c.
1769 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Fixed the silc_server_remove_clients_by_server's channel
1772 key re-generation. The hash table handling was incorrect
1773 and would not work with many channels. Affected file is
1776 * Fixed some memory leaks around the server code.
1778 * Rewrote the silc_server_get_users_on_channel to support IPv6
1779 based Client ID's. Affected file silcd/server.c.
1781 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1782 specification. However, a separate document must be written
1783 to define the detailed signing procedure and the payload
1784 associated with the flag. Defined the flag to the
1785 lib/silccore/silcchannel.h as well.
1787 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Changed the dynamic tables to static size tables in the
1790 lib/silccrypt/silchmac.c.
1792 * Removed GCC dependencies from the code. A patch by cras.
1794 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Do not show the error "Error receiving packet bla bla"
1797 in server if it really was not an error (-2 means that reading
1798 is pending). Affected file silcd/server.c.
1800 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Fixed a possible crash in silc_server_remove_clients_by_server
1803 in silcd/server.c. Fixed there also some memory leaks.
1805 * Fixed the silc_idlist_replace_client_id. It could replace
1806 wrong key in the hash table. Affected file silcd/idlist.c.
1808 * Do not check whether there are global users on the channel
1809 if the channel->global_users is FALSE. Affected functions
1810 silc_server_remove_from_one_channel and
1811 silc_server_remove_from_channels in silcd/server.c. Also,
1812 do not check if the removed client is local as we can be
1813 sure that global client was not removed from the channel
1814 and checking for global users is not needed.
1816 * The silc_server_remove_clients_by_server now re-generates
1817 the channel keys correctly for those channels that had
1818 clients removed from them. Affected file silcd/server.c.
1820 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Found the reason of random crashes in the server. We weren't
1823 ignoring the SIGPIPE signal (which can be sent in write())
1824 and it crashed the server. Affected file silcd/silcd.c.
1826 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1828 * Assure that sock->user_data is not NULL in the function
1829 silc_server_packet_send in silcd/packet_send.c.
1831 * Disconnect the remote connection if it could not be added
1832 to any ID lists in the server. The affected file is
1835 * Check in silc_server_packet_send[_real/dest] that the
1836 socket is not disconnecting and ignore the data if it is.
1837 Affected file silcd/packet_send.c.
1839 * Define inline to __inline on native WIN32 compilation.
1840 Affected file includes/silcwin32.h.
1842 * Added some explicit type casts for inline code since MSVC
1843 require them. Affected files lib/silcutil/silcbuffer.h,
1844 lib/trq/silcdlist.h and lib/trq/silclist.h.
1846 * Print warning in log files from now on if the packet
1847 decryption fails. Affected file silcd/server.c.
1849 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Changed the `say' client operation's interface to accept
1852 new `type' argument to indicate the type of the message sent
1853 by the library. The application may filter the library's
1854 messages according the type. The affected file is the
1855 lib/silcclient/silcapi.h.
1857 * Added two new functions to lib/silcclient/silcapi.h:
1858 silc_client_del_client and silc_client_del_client_by_id.
1859 Affected file lib/silcclient/idlist.c.
1861 * Moved the clientincludes.h from includes/ to silc/ and
1862 serverincludes.h from includes/ to silcd/.
1864 * The modes for the CMODE and CUMODE are now passed as
1865 uint32 for application with COMMAND_REPLY. The affected
1866 file is lib/silcclient/command_reply.c.
1868 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * /WHOIS without arguments shows client's own information.
1871 Affected file lib/silcclient/command.c.
1873 * Changed PING to not accept any arguments. The specs
1874 says that client can ping only the connected server so
1875 requiring an argument is not needed. Affected file is
1876 lib/silcclient/command.c.
1878 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Fixed a fatal bug in private message sending and reception
1881 encryption and decryption when using private message keys.
1882 The implementation was incorrect and did not follow the
1883 specification. It causd that some of the message were
1884 lost since it did not use the sending and receiving keys
1885 as the protocol suggests. This has been fixed and will cause
1886 incompatibilities with older clients when sending private
1887 message encrypted with private message keys. Affected files
1888 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1889 and various other in Irssi SILC Client.
1891 Added `responder' boolean argument to the functions
1892 silc_client_add_private_message_key[_ske] to indicate when
1893 the key is added as responder or initiator of the key
1896 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Removed the silc_ske_check_version function and created
1899 a SilcSKECheckVersion callback. Added also a function
1900 silc_ske_set_callbacks that is now used to set all SKE
1901 callbacks. The callback functions are not given to
1902 the SKE functions anymore, but this function is used to
1905 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1907 * Added `silc_version' argument to the silc_client_alloc
1908 to define the version of the application for the library.
1909 The library will use the version string to compare it
1910 against the remote host's (usually a server) version
1911 string. Affected file lib/silcclient/silcapi.h
1913 * Added the KE protocol context to Key Agreement context
1914 in client library so that we can abort the SKE if it
1915 is in process when we get timeout. Affected file is
1916 lib/silcclient/client_keyagr.c.
1918 * Do not resolve the client ID forever if it returns in the
1919 first time that such client does not exist. This was done
1920 for example with private message. Affected file is
1921 lib/silcclient/client_prvmsg.c.
1923 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Do not add regex.h for WIN32. The affected file
1926 includes/silcincludes.h.
1928 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1929 not work yet 100%. It generates the DLL's automatically
1930 when compiling with --with-win32 under cygwin.
1932 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * lib/contrib/regex.c is not compiled on WIN32.
1936 * Added silc_net_get_socket_opt function to the
1937 lib/silcutil/silcnet.h.
1939 * Added includes/silcwin32.h for WIN32 specific includes
1942 * Do not use ptime structure or any of the posix process
1943 functions on WIN32 in lib/silccrypt/silrng.c.
1945 * Added silc_gettimeofday to provide generic function
1946 for struct timeval on all platforms. Added the function
1947 to lib/silcutil/silcutil.h.
1949 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1952 library as they clearly belong there. As a plus side we
1953 can make the actual socket connection routines platform
1956 Added also new generic function silc_socket_read and
1957 silc_socket_write (that used to be silc_packet_[read/write].
1958 The implementation of these are platform specific.
1960 * Added WIN32 specific routines of silc_socket_[read/write]
1961 to lib/silcutil/win32/silcwin32sockconn.c.
1963 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Added preliminary support for native WIN32 compilation under
1966 cygwin (using the -mno-cygwin option for GCC) to the
1967 ./configure.in.pre. The --with-win32 now prepares the
1968 compilation for native WIN32.
1970 * Rewrote the SILC Scheduler interface in the file
1971 lib/silcutil/silcschedule.h. The scheduler is now context
1972 based and does not have anymore any global static scheduler.
1973 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1974 and created lib/silcutil/win32 directory for WIN32 based
1977 * Added Unix specific network routines to the
1978 lib/silcutil/unix/silcunixnet.c and the old
1979 lib/silcutil/silcnet.c includes now only generic routines.
1981 Added WIN32 specific network routines to the
1982 lib/silcutil/win32/silcwin32net.c.
1984 * Added Unix specific utility functions from the
1985 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1987 * Added WIN32 SILC Scheduler to the file
1988 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1991 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Do not handle JOIN notify in the server if the target client
1994 is not registered (idata->registered == FALSE). The affected
1995 file is silcd/packet_receive.c.
1997 * Update the nickrec->founder in event_cumode in the Irssi SILC
1998 client. Affected file irssi/src/silc/core/silc-channels.c.
2000 * Fixed the CUMODE_CHANGE notify handling in the server when
2001 server and router are announcing their clients on channels.
2002 Now the mode changes are saved and notified correctly. The
2003 affected file is /silcd/packet_receive.c.
2005 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2006 They really did not replace the cache entry in the ID Cache.
2007 Now they do that. Affected file silcd/idlist.c.
2009 * Fixed the KICK notify handling in the Irssi SILC client to
2010 update the channel records so that the kicked client does not
2011 appear to be on the channel. The affected file is
2012 irssi/src/silc/core/silc-channels.c.
2014 * Always update the conn->current_channel when executing command
2015 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2017 * Fixed the KILL notify handling in Irssi SILC client to remove
2018 the killed client on all channels.
2020 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Fixed the silc_parse_command_line to remove extra spaces
2023 from the start and end of the arguments. Affected file is
2024 lib/silcutil/silcutil.c.
2026 * Cancel and free any active protocol in the function
2027 silc_server_close_connection. Affected file silcd/server.c.
2029 * Cancel and free any active protocol in the function
2030 silc_client_close_connction. Affected file is
2031 lib/silcclient/client.c.
2033 * Do not execute the KILL command for clients that are in
2034 history (ie. they are not in the network). Affected file is
2037 * Fixed KILL notify handling, client does not crash anymore.
2038 Affected file irssi/src/silc/core/silc-channels.c.
2040 * Reduced the default packet buffer size from 2048 to 1024 in
2041 lib/silccore/silcpacket.c.
2043 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2044 counter to the SKE context that is incresed when the SKE library
2045 performs async operation outside the library. If the outside
2046 process frees the SKE context and FREED status will be set
2047 and the library will detect after the sync operation that the
2048 libary is freed. The affected files are
2049 lib/silcske/silcske[_status].[ch].
2051 * Resolve the client entry information in the function
2052 silc_client_channel_message to assure that NULL pointer is not
2053 passed as client entry to the application. */
2055 * Fixed the task timeout calculation to assure that there is
2056 never negative timeouts. The affected file is
2057 lib/silcutil/silcschedule.c.
2059 * Fixed the channel user mode notification sending in server.
2060 It was sent point-to-point to the router (or to server by router)
2061 but it needs to be destined to a channel. The routines now
2062 supports sending the channel user mode notifys to the channels
2063 when announcing clients and channels. Affected files are
2064 silcd/server.c and silcd/packet_receive.c.
2066 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2067 It did not actually replace the old channel entry in the cache.
2068 Affected file lib/silcclient/client_notify.c.
2070 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2072 * Fixed a possible crash in silc_packet_send_prepare. It now
2073 assures always that there is enough space in the buffer and
2074 at the tail area of the buffer (for MAC).
2076 Fixed the inbound buffer reallocation in silc_packet_read.
2077 It was old code and did not handle the reallocation correctly.
2080 The affected file is lib/silccore/silcpacket.c.
2082 * Fixed buffer overflow in silc_parse_nickname in the file
2083 lib/silcutil/silcutil.c.
2085 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * make install generates new server keys only if there is not
2090 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2093 Added check that if the NOREPLY is set then we will not send
2094 the away message. This avoids infinite loop of away messages
2095 if both clients are away. The affected file is
2096 lib/silcclient/client_prvmsg.c.
2098 * Fixed client crash if /NICK was given without arguments.
2099 Affected file lib/silcclient/command.c.
2101 * Server does not send the invite list in INVITE command back
2102 to the client if the list was not altered. Added this notion
2103 to the protocol spec as well. Affected file silcd/command.c.
2105 Fixed possible crash in INVITE command by checking the
2106 value of silc_server_get_client_route command.
2108 * Fixed the INVITE notify type handling. The arguments are now
2109 taken in correct order and client does not crash. The affected
2110 file is irssi/src/silc/core/silc-channels.c.
2112 Removed the "Inviting xxx to channel" message from the
2113 client library away and let the application handle it.
2114 Affected file lib/silcclient/command.c. Added that message
2115 to Irssi SILC client's message formats.
2117 * Fixed CMODE command crash in client. It now checks the
2118 amount of arguments correctly and does not crash. The affected
2119 file is lib/silcclient/command.c.
2121 * Do not create new channel automatically in silc_channels_join
2122 but check whether the channel by that name already exists.
2123 Affected file irssi/silc/core/silc-channels.c.
2125 * Do not send the SERVER_SIGNOFF to router if the disconnected
2126 entity was the router. Affected file silcd/server.c.
2128 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2129 SILC client as it was missing from there.
2131 Added the handling of the KICK notify to the Irssi SILC client
2132 as it was missing. Added "you have been kicked" message to
2133 Irssi SILC client's message modules formats.
2135 Added the handing of the KILL notify to the Irssi SILC client
2136 as it was missing. Added the kill message module formats
2139 The affected file is irssi/src/silc/core/silc-channels.c.
2141 * The router did not save the channel mode the server announced.
2142 Affected file silcd/packet_receive.c.
2144 * Fixed a possible crash in INFO command in server. If the
2145 server did not provide the server info it crashed. Affected
2146 file silcd/command.c.
2148 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Fixed the GETKEY command in the server to check also the
2151 global list. Otherwise the GETKEY would not work correctly
2152 in normal SILC server. Affected file silcd/command.c.
2154 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Fixed GETKEY crash, it crashed if the command did not succseed.
2158 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2161 is now real and not just an macro interface to GMP.
2163 Removed the entire GMP from the source tree and imported new
2164 NSS MPI library instead. Reason for removing GMP is that it is
2165 extremely large and compiles extremely slow. The NSS MPI
2166 is only a few files and compiles in less than 10 seconds.
2167 The speed is also about the same as GMP. The MPI is imported
2168 to lib/silcmath/mpi.
2170 If the system has GMP installed we will still use the GMP.
2171 If it is not then the NSS MPI will be compiled.
2173 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Merged a long nickname (127 characters long) crash bugfix from
2176 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2178 * Merged a freed memory reference bugfix from Irssi CVS tree.
2179 Affected file irssi/src/core/commands.c.
2181 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2183 * Added the server's public key sving and verification to the
2184 server when performing the SKE. This was missing and the
2185 remote server's (or router's) public key was accepted without
2186 checking whether we have it previously or trust it at all.
2187 Affected file silcd/protocol.c.
2189 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Check in the silc_server_timeout_remote if protocol is active
2192 and make sure that the protocol's final callback is called so
2193 that all memory if freed. Affected file silcd/server.c.
2195 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * silc_server_whois_send_reply crashed the server if the nickname
2198 was 127 characters long. Affected file silcd/command.c.
2200 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Added sanity check to the silc_server_new_client. If the hostname
2203 is provided inside username then check that the provided hostname
2204 really is the same as the resolved one. If the hostname was not
2205 resolved then check it from the public key. Affected file is
2206 silcd/packet_receive.c.
2208 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2209 if the server disconnected us and the connection is not valid
2210 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2212 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2213 the library to the lib/silcutil/silcutil.[ch].
2215 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Close log file after open. Affected file
2218 lib/silcutil/silclog.c.
2220 * Check whether sock == NULL in silc_client_send_packet and return
2221 if it is. Affected file lib/silcclient/silcclient.c.
2223 * Check rec->entry == NULL in the Irssi SILC Client before
2224 sending the channel message. Affecte file is
2225 irssi/src/silc/core/silc-servers.c.
2227 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Merged a splitted window bugfix from Irssi CVS tree. The
2230 affected file is irssi/src/fe-text/textbuffer-view.c.
2232 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2233 It did not print nickname.
2235 * Improved the distributions system a bit.
2237 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2240 irssi/src/fe-text/gui-window.c.
2242 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2243 to in-active server. The affected file is
2244 irssi/src/silc/core/client_ops.c.
2246 * Resolve the client in USERS command reply if the entry does
2247 not have username resolved. The affected file is
2248 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2249 command to WHOIS command to really resolve stuff. The USERS
2250 is not used any more in any critical section so WHOIS can
2251 be used even though it might be slower than IDENTIFY.
2253 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2256 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2258 * Changed the protocol API a bit more consistent in the
2259 lib/silccore/silcprotocol.[ch].
2261 * Changed the following headers to ROBODoc format:
2263 lib/silccore/silcpayload.h
2264 lib/silccore/silcprotocol.h
2265 lib/silccore/silcsockconn.h
2267 All core library headers are now formatted.
2269 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Fixed a bug in Irssi SILC client; do not show that you are
2272 server/router operator if you really are not. Affected file is
2273 irssi/src/silc/core/client_ops.c.
2275 * Renamed silc_command_free_payload to silc_command_payload_free.
2276 Affected file lib/silccore/silccommand.h
2278 * Added silcmath.h to include the prototoypes of various routines
2279 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2282 * Changed the following headers to ROBODoc format:
2284 lib/silccore/silcchannel.h
2285 lib/silccore/silccommand.h
2286 lib/silccore/silcid.h
2287 lib/silccore/silcidcache.h
2288 lib/silccore/silcmode.h
2289 lib/silccore/silcnotify.h
2290 lib/silccore/silcpacket.h
2291 lib/silcmath/silcmath.h
2293 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2295 * Added checking to the server code not to start the server if
2296 ciphers and stuff are not configured properly. Affected files
2297 silcd/serverconfig.[h] and silcd/server.c.
2299 * Changed the layout of the header files of the public interfaces
2300 in the SILC libraries. The new layout supports ROBODoc
2301 documentation tool (and some others) so that it is easy to create
2302 a library reference manual. All the other headers and source
2303 code must still follow the CodingStyle document. Also source
2304 code must not include these ROBODoc stuffs, only the headers.
2305 Furthermore, all public interface headers must now be named
2306 by using `silc' prefix, example: silcapi.h, silccipher.h.
2307 Some files were renamed due to this. All the other headers
2308 must not be used as public interfaces. I will update the
2309 CodingStyle document later. Changed following headers, so far:
2311 lib/silcclient/silcapi.h
2312 lib/silccore/silcauth.h
2313 lib/silccore/silcprivate.h
2314 lib/silccrypt/silcdh.h
2316 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Removed silc_client_packet_send_flush from the client library
2321 as it is not needed. Affected file lib/silcclient/client.[ch].
2323 * Added printing of message of unresolved authentication method
2324 to the Irssi SILC client. Added it to the module formats.
2325 Removed the same message from the client library.
2327 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2329 * Added new distribution feature, DISTLABEL. Every distribution
2330 can define own preprocessor label that can be used in the
2331 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2332 file distributions, acconfig.h.pre and prepare.
2334 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2336 * Added Makefile.defines_int to include the actual definitions
2337 for Makefile.defines.in. Tested the new distribution system,
2338 created distributions and tested installation.
2340 * Added AWAY message printing to the Irssi SILC client. Added
2341 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2343 * Added SCONNECT command to call the SILC's CONNECT command.
2344 Cannot use CONNECT directly since Irssi uses that internally.
2345 Affected file irssi/src/silc/core/silc-servers.c.
2347 Added ACTION local command. It is same as ME command but takes
2348 the channel as mandatory argument.
2350 Rewrote some of the Irssi's help files to suite for SILC
2353 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Added Makefile.defines[.in] that should for now on be included
2356 in all Makefile.am file in the source tree. That file includes
2357 all common compilation definitions for SILC source tree.
2359 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Minor changes to the ./prepare script to change the package
2362 name according the distribution name to the configure.in.
2364 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Created new distribution system. Added file `distributions'
2367 that defines all the distributions that can be created out of
2368 the SILC source tree. The ./prepare script now reads that
2369 file to determine how to prepare the distributions. The
2370 first argument to the ./prepare is the name of the distribution
2371 and second is the version of the distribution. If given
2372 without arguments it creates the default (toolkit) distribution
2373 with the default version (defined in ./prepare).
2375 All Makefile.am files that are subject to the distributions
2376 are now named as Makefile.am.pre. These are ./Makefile.am
2377 and lib/Makefile.am. Others may be changed later.
2379 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Added invite list, ban list, some key management and connection
2382 error message printing to module formats in the Irssi SILC client.
2384 * Added new silc_client_set_away_message to set the away message
2385 that is back to the person who sent private message. The
2386 affected file lib/silcclient/silcapi.h and the
2387 lib/silcclient/client_prvmsg.c.
2389 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Fixed the private message sending in the Irssi SILC client,
2392 added local command KEY to the Irssi SILC client.
2394 Added key management and key agreement message formats to the
2395 irssi/src/fe-common/silc/module-formats.[ch].
2397 Added USERS (alias WHO) printing, server/router operator
2398 indication and LIST command printing to the module formats.
2400 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Fixed channel joining notify handling, cumode notify handling
2403 from Irssi SILC client.
2405 * Added SILC specific module-formats to the Irssi SILC client so
2406 that SILC specific message hilighting, colors etc is possible.
2407 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2409 Added channel mode, channel user mode, actions, notices,
2410 whois and whowas printing to the the module-formats.c.
2412 * Fixed a bug in channel deletion in the server. The channel
2413 is not left to the cache even if the channel founder auth mode
2414 is set when there are no users anymore on the channel. Affected
2415 file silcd/server.c.
2417 * The silc_net_localhost now resolves the entire hostname including
2418 the domain name. Affected file lib/silcutil/silcnet.c.
2420 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Changed the ask_passphrase client operation to be ascynchronous.
2423 It has now a completion callback and a context that the
2424 application must call after it has got the passphrase from
2425 the user. Affected files lib/silcclient/silcapi.h,
2426 lib/silcclient/protocol.c, lib/silcclient/command.c and
2429 Added SilcAskPassphrase callback that the application calls
2430 to deliver the passphrase to the library.
2432 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2433 The public key verification and especially a certificate
2434 verification is asynchronous procedure.
2436 Added new SILC_SKE_STATUS_PENDING status to indicate the
2437 request is pending and a callback will be called to finalize
2440 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2441 indicate that remote end did not send its public key (or
2442 certificate), even though we require it. Added check for this
2443 condition in the SKE. This was a security bug, now fixed.
2445 Defined new SilcSKEVerifyCbCompletion callback that is called
2446 when the verification process is completed.
2448 The affected files lib/silcske/silcske_status.h and
2449 lib/silcske/silcske.[ch].
2451 * Changed the verify_public_key client operation to be async
2452 as well. Defined SilcVerifyPublicKey callback that is used to
2453 indicate the success of the public key verification process.
2455 Changed the server and client to use the new async client
2458 * Changed the Irssi SILC client's internal scheduler to be called
2459 twice as many times as it used to be. As a result the client
2460 should be a bit faster now. Affected file is
2461 irssi/src/silc/core/silc-core.c.
2463 * Added support to Irssi SILC client of asynchronous public key
2464 verification and passphrase inquiry. Affected file is
2465 irssi/src/silc/core/silc-core.c.
2467 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Do not say "You have left channel %s" in client library.
2470 Moved it to the application. Affected files are
2471 lib/silcclient/command.c and silc/client_ops.c.
2473 * Fixed silc_client_get_clients. Command context was not
2474 duplicated and was freed memory in the callback. Affected
2475 file lib/silcclient/idlist.c.
2477 * Do not say "you are now talking..." on JOIN command in the
2478 client library. The appliation must handle it.
2480 * Do not say ".. changed topic to" in command reply in the
2481 client libary. The application must handle it.
2483 * Fixed TOPIC command sending in the client library.
2485 * Fixed a memory leak in silc_client_command_free in the file
2486 lib/silcclient/command.c.
2488 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Imported a modified version of Irssi client to the source tree.
2491 The Irssi will be used to create a new client called
2492 Irssi SILC. Imported to irssi/.
2494 Added silc_core_init_finish function to the Irssi. Affected
2495 file irssi/configure.in.
2497 A lot changes in the Makefile.ams around the irssi tree.
2499 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2501 * Do not rehash if the new size is same as the old size of the
2502 hash table, in the silc_hash_table_rehash*. The affected file
2503 lib/silcutil/silchashtable.c.
2505 * Replaced hash_table_del_by_context calls from the server
2506 (when channel->user_list and client->channels) to the
2507 hash_table_del as it is sufficient and faster.
2509 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Added silc_hash_table_list, silc_hash_table_get and the
2512 SilcHashTableList structure to provide an alternative way to
2513 traverse the hash table. The affected files are
2514 lib/silcutil/silchashtable.[ch].
2516 * Changed the server's idlist routines to use the hash table
2517 routines to optimize the code.
2519 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Replaced the client entry's `channel' list and channel entry's
2522 `user_list' list to hash tables for optimized lookup. Changed
2523 the code to use the hash table interface around the code.
2524 Affected file lib/silcd/idlist.[ch].
2526 * Added `auto_rehash' boolean argument to the function
2527 silc_hash_table_alloc to indicate whether the hash table should
2528 auto-rehash when it thinks is appropriate time. It will
2529 increase the hash table size if the there is twice as much
2530 entries in the table than the size of the table, and will
2531 decrease the size if there are twice as less entries than
2532 the size of the table.
2534 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2538 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * silc_idcache_purge_by_context deletes the entry now by context
2541 as it is supposed to do. Affected file lib/silccore/idcache.c.
2543 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2544 client is not anymore valid (WHOWAS givens the info) and not
2545 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2547 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Removed the `data' and `data_len' arguments from the ID Cache
2550 interfaces and added `name' argument. ID Cache does not handle
2551 anymore the binary data only a names associated with given ID.
2553 * When hashing a Client ID with silc_hash_id the entire ID is
2554 not hashed anymore, instead only the hash of the Client ID is
2555 hashed. This way we can access the Client ID from the cache
2556 with Client ID but with the hash of the ID (which is a hash of
2557 the nickname) as well without any difference in performance.
2559 Added also silc_idcache_find_by_id_one_ext to do one on one
2560 searching when we have the actual ID. Added also function
2561 silc_hash_client_id_compare. The affected files are
2562 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2564 * When hashing the name associated with a ID it is always done
2565 in lowercase. This way we can access the cache without worrying
2566 about case-sensitivity, even though, for example nicknames are
2569 * Fixed a bug in server with channel message sending. It put
2570 wrong ID type as destination ID. The affected file
2571 silcd/packet_send.c.
2573 * silc_idcache_del_by_context now deletes from all hash tables
2574 by context. Affected file lib/silccore/idcache.c.
2576 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Changed the client library to use the new ID Cache interface.
2579 Changes around the source tree.
2581 * Added silc_hash_table_rehash_ext to rehash with specific
2582 hash function. Affected file lib/silcutil/silchashtable.[ch].
2584 * Added silc_hash_string_compare to compare two strings in the
2585 hash table. Affected file lib/silcutil/silcutil.[ch].
2587 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Added new function silc_idcache_del_by_context into the
2590 lib/silccore/idcache.[ch].
2592 * Changed the server's ID list routines to use the new ID Cache
2593 interface. Changes around the source tree.
2595 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2597 * Added silc_hash_table_del[_by_context]_ext functions in to the
2598 lib/silcutil/silchashtable.[ch].
2600 Removed silc_hash_table_find_all* routines and added new
2601 silc_hash_table_find_foreach to replace them.
2603 Added silc_hash_table_replace_ext function as extended
2604 replacing function. Separated the simple hash table interface
2605 from the extended hash table interface in the file
2606 lib/silcutil/silchashtable.h.
2608 * Fixed minor bugs and changed it to use some of the new
2609 hash table functions in lib/silccore/idcache.c
2611 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Added new function silc_hash_table_find_all to return all keys
2614 in the hash table by the specified key. As the hash table is
2615 collision resistant it also makes it possible to have several
2616 duplicate keys in the hash table. This function may be used to
2617 find all of the keys from the hash.
2619 Added user_context arguments to the SilcHashFunction,
2620 SilcHashCompare and SilcHashDestructor to deliver user specified
2623 Added new fuctions silc_hash_table_find[_all]_ext to do
2624 extended lookup with specified hash and compare functions and
2625 specified user contexts.
2627 Added new function silc_hash_table_add_ext to add the key
2628 with specified hash function and user context.
2630 Added new function silc_hash_table_foreach to traverse all
2631 entrys in the hash table. Added SilcHashForeach callback
2634 Added new function silc_hash_table_del_by_context to delete
2635 the entry only if the context associated with the key matches.
2637 Affected files are lib/silcutil/silchashtable.[ch].
2639 * Removed silc_hash_[server/client/channel]_id and added just
2640 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2641 silc_hash_id_compare to compare two ID's using as the hash table
2642 comparison function. Added also silc_hash_data to hash
2643 binary data and silc_hash_data_compare to compare it.
2645 * Removed silc_idlist_find_client_by_hash as it is not needed
2646 anymore. Affected file silcd/idlist.[ch].
2648 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2649 to use internally the SilcHashTable. The new ID Cache is a lot
2650 faster than the old one. Some of the ID Cache interface was also
2651 rewritten and obsolete and stupid functions were removed.
2653 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added entry_count field to the SilcHashTable to keep the number
2656 of the entries in the table. Implemented the function
2657 silc_hash_table_rehash. Added new function
2658 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2660 Fixed a minor bug in silc_hash_table_free.
2662 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2663 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2664 into the lib/silcutil/silcutil.[ch].
2666 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Implemented a collision resistant hash table into the
2669 lib/silcutil/silchashtable[ch]. See the header and the source
2670 for the SilcHashTable API.
2672 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * Merged dotconf version 1.0.2 into lib/dotconf.
2676 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Do not compile anything in lib/silcsim/* if the SIM support
2679 is not enabled. The tree should now compile without problems
2682 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * Compiled the SILC under cygwin. Compiled and tested briefly
2685 without problems. More tests needed. The SIMs didn't compile
2688 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2690 * Fixed possible crash in silc_get_username in the
2691 lib/silcutil/silcutil.c.
2693 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * Fixed a va_arg in silc/client_ops.c.
2697 * Oops, RC5 routines were named AES and caused some problems
2698 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2700 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Added new SilcIDIP structure into the lib/silccore/id.h and
2703 replaced the old `ip' fields from all SILC ID's to that type.
2704 This is a step towards IPv6 support.
2706 The silc_id_get_len takes now the ID as an extra argument.
2707 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2708 both IPv4 and IPv6 based ID's.
2710 The affected files are lib/silccore/id.[ch] and other files
2711 around the tree using these routines.
2713 * Removed the ID length arguments in server from various
2714 silc_server_send_notify_* routines -> they are not needed
2717 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Fixed memory leak in silc_encode_pem_file in the file
2720 lib/silcutil/silcutil.c.
2722 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Check minor version as well in the SKE. Affected files are
2725 silcd/protocol.c and lib/silcclient/protocol.c.
2727 * Added --identifier option to the server so that an identifier
2728 can be when creating the public key for the server. Affected
2729 file is silcd/silcd.c.
2731 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2732 lib/silccrypt/silcpkcs.c.
2734 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Register default ciphers and stuff when using -C option with
2737 the server. Affected file sildc/silcd.c.
2739 * Put back the servers public key filename format, it is better
2740 than the new one. For now, the client keys are saved with the
2741 new filename format. The affected file silc/client_ops.c.
2743 * Implemented the Cipher API for the rest of the ciphers that
2744 did not implement it or implemented it the wrong way.
2746 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Register default ciphers and stuff when using the -S option
2749 in the client. Affected file silc/silc.c. Same also when
2750 creating new key pair with -C option.
2752 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Fixed the silc_verify_public_key client operation function to
2755 save the public keys differently. The fingerprint is now
2756 used as filename and not the hostname. This way also the
2757 client keys are saved uniquely and not with hostnames. The
2758 affected file is silc/client_ops.c.
2760 * Trimmed the silc_hash_fingerprint function to remove extra
2761 whitespaces from the end of the fingerprint. The affected
2762 file is lib/silccrypt/silchash.c.
2766 * Added silc_cipher_register_default function to register all
2767 default ciphers. It can be used when configuration files
2768 does not exist and the application does not want any specific
2769 ciphers in any specific order.
2771 The SilcDList is now used as silc_cipher_list dynamically
2772 allocated cipher list. Removed the static list all together
2773 and now all ciphers must be allocated to the dynamic list.
2774 The silc_cipher_alloc routine was changed to check only the
2777 All silc_cipher_* routines that used to return int returns
2780 The affected files lib/silccrypt/silccrypt.[ch].
2782 * The same thing was done to silc_hash_* as for silc_cipher_*
2783 routines. Affected files lib/silccrypt/silchash.[ch].
2785 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2786 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2787 Added also silc_pkcs_[un]register[_default] functions.
2788 Removed the data_context from the PKCS API.
2790 * Added silc_hmac_register_default function to register default
2791 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2792 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2793 to unregister all hmacs at once.
2795 * Register the default ciphers, hash functions, PKCSs and HMACs
2796 if client's configuration file does not exist. The affected
2799 * The client did not load the hash functions from the SIM
2800 modules at all. Added support for this. Affected file is
2801 silc/clientconfig.c.
2803 * When decoding public key with silc_pkcs_public_key_decode, check
2804 the supported algorithm only if PKCS are registered. Affected
2805 file lib/silccrypt/silcpkcs.c. The same was done with the
2806 silc_pkcs_private_key_decode.
2808 * Fixed the SILC List routines to keep the list always in order.
2809 It used to change the list's order when traversing the list but
2810 not it preserves the order. Affected file lib/trq/silclist.h.
2812 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Added the client library to use the SilcSocketConnection's
2815 reference counter (by silc_socket_dup) to prevent the bug that
2816 the socket object may be freed underneath async operation.
2818 * The name resolv library checking fixes in the configure.in.pre.
2821 * Created new version of the protocol drafts for future
2822 development. The -03 drafts are the ones that will be changed
2823 in the trunk now and the -02 will remain as they are.
2825 * Send list of CUMODE notifys to the router when announcing
2826 the channel users to the router. Affected file silcd/server.c.
2827 If the router receiving channel founder CUMODE for a channel
2828 that already has channel founder it will send CUMODE notify
2829 to the sender to remove the channel founder rights from the
2830 announced client. Affected file silcd/packet_receive.c.
2832 * The CUMODE notify may now use Server ID as well as the entity
2833 who changes the mode. Updated protocool specs.
2835 * Updated INSTALL and README files.
2837 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * New web pages in the http://silc.pspt.fi. The pages was
2844 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * Implemented the [DenyConnectin] config section in the server.
2847 Added silc_server_config_denied_conn to check whether incoming
2848 connection is denied. Affected file silcd/serverconfig.[ch].
2850 * Do not check the ports when checking the incoming configuration
2851 data if the port is 0, meaning any. Affected file is
2852 silcd/serverconfig.c.
2854 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Fixed buffer overflow in silc_string_compare in the file
2857 lib/silcutil/silcutil.c.
2859 * Fixed double free in silc_server_command_leave in the file
2862 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Fixed the version checking in the server. Affected file is
2867 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Fixed the configuration data fetching when accepting new
2870 connections in the server. Affected file silcd/server.c.
2872 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Added `sender_entry' argument to the function
2875 silc_server_packet_relay_to_channel so that we can check
2876 whether some destination actually belongs to the same route
2877 the sender belongs (ie, we must not resend the packet to the
2878 sender). Affected file silcd/packet_send.[ch].
2880 * Added `servername' field to the SilcClientEntry in the server
2881 to hold the name of the server where client is from. Affected
2882 file is silcd/idlist.h.
2884 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Moved the channel message encrypting in the router betwen
2887 router connections from silc_server_channel_message to the
2888 silc_server_packet_relay_to_channel since we want to check
2889 whether we have anybody channel before encrypting anything.
2890 Affected files silcd/packet_[receive/send].c.
2892 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Fixed the [AdminConnection] server config section to support
2895 multiple entries. Affected file silcd/serverconfig.c.
2897 * Added support into the server to check the validity of the
2898 incoming connection before executing any KE or authentication
2901 * The connection configuration is now saved to the KE and
2902 connection auth protocol contexts and not fetched anymore in
2903 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2905 * The local hosts listenning address and port is also resolved
2906 now when starting the server. We want to have the socket object
2907 to include the real address and port for the listener. Added
2908 new function silc_net_check_local_by_sock into the files
2909 lib/silcutil/silcnet.[ch].
2911 * Fixed a broadcast bug in server -> do not broadcast if we
2914 * Fixed a routing bug. Do not route broadcast packets ever.
2915 Broadcast packets must be processed always and not routed since
2916 they may be destined to some other host than yourself and thus
2917 would get routed without no good reason. Affected file is
2920 * Added function silc_server_config_is_primary_route to check
2921 whether primary router connection has been configured (a router
2922 configuration that we are initiating). If there is not, we
2923 will assume that there is only two routers in the SILC network
2924 and we will use the incoming router connection as our primary
2925 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2927 * Changed the order of the broadcasting. Broadcast _after_ the
2928 packet has been processed not before. Affected file is
2931 * Fixed a [ClientConnection] parsing bug. The port was never
2932 parsed correctly thus resulting to port 0. Affected file
2933 silcd/serverconfig.c.
2935 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2936 argument and did not set the broadcast packet flag. Affected
2937 file silcd/packet_send.c. Fixed same bug in the function
2938 silc_server_send_notify as well.
2940 * If we receive NEW_ID packet for our own ID in the server, ignore
2943 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Removed the nickname from the Private Message Payload.
2948 Updated the code and the protocol specs.
2950 * Updated protocol specs for submitting to the IETF.
2952 * Tweaked the Random Number Generator a bit. Affected file
2953 lib/silccrypt/silcrng.c. Exported a new function
2954 silc_rng_[global]_add_noise which can be used to add more
2957 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Do not parse packets with different timeout when protocol
2960 is active -> may cause problem with rekey. Affected file
2963 * When server receives signoff notify it must not create
2964 new channel key if the client is on any channels since the
2965 sender of the signoff notify will create it.
2967 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added printing of error messages during SKE protocol from the
2970 failure packet sent by server during SKE. Affected file
2973 * Removed the client's failure_callback handling with timeout
2974 and handle it immediately when received.
2976 * The SKE library returned wrong type in SUCCESS and FAILURE
2977 packets. They must be 32 bit MSB not 16 bit MSB.
2979 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Ok, rewrote the logic of the re-key and now it seems to work.
2982 I tested it on high traffic with frequent re-keys without
2983 problems. Added hmac_receive (and renamed hmac to hmac_send)
2984 in SilcClientConnection in lib/silcclient/client.h and
2985 in SilcIDListData in silcd/idlist.h. Also, removed the
2986 SilcPacketParserContext's cipher and hmac fields as they are
2987 not needed anymore and actually caused some problems when
2988 the ciphers and hmac's changed underneath the packet parser.
2990 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * If re-key protocol is active then process the incoming packets
2993 synchronously since we must assure that icoming packets encrypted
2994 with the old key is processed before the new keys is set to
2995 use. This is true other packets than for REKEY packets.
2996 Affected file silcd/server.c. The same was done to client library
2997 as well, affected file lib/silcclient/client.c.
2999 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Fixed bug in client and server to accept the force send if
3002 the packet is send from silc_[server/client]_packet_process
3003 function. Otherwise the packets are never delivered, oops.
3005 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Disable force sending of packets when REKEY protocol is active.
3008 We must assure that no packet is sent directly when rekey is
3009 performed. All packets must be sent through packet queue.
3010 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3011 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3012 function is silc_[server/client]_packet_send_real to check
3015 * Replaced the SIM paths from example config files to
3016 /usr/local/modules. Also, make install creates now
3017 /usr/local/silc/logs directory to hold all the SILC server
3020 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Made the configure.in.pre work on Solaris. Patch by salo.
3024 * Made all ciphers compatible with non-x86 machines. Defined
3025 CBC mode macros into lib/silccrypt/ciphers_def.h.
3027 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Fixed the make install.
3031 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * When MAC computation fails the silc_packet_decrypt returned 0
3034 even though it was supposed to return -1. Fixed this. The
3035 affected file is lib/silccore/silcpacket.c.
3037 * Do not replace the config files in /etc/silc (in make install)
3038 if they already exist. Affected file ./Makefile.am.
3040 * Do not send re-key packets immediately but through packet queue.
3041 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3043 * Changed silc_net_check_host_by_sock to return FALSE if the
3044 IP/DNS could not be resolved. Though, it returns the IP address
3045 now even if it could not resolve it (but returns also FALSE).
3046 Affected file lib/silcutil/silcnet.[ch].
3048 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added silc_pkcs_decode_identifier to decode the public key's
3051 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3052 Added also silc_pkcs_free_identifier. Added also new context
3053 SilcPublicKeyIdentifier.
3055 * Added -S option to the silc client. It is used to dump the
3056 contents of the specified public key file.
3058 * Changed the PKCS api to return the public key length when
3059 setting the public key.
3061 * Fixed a fatal bug in the public and private key file loading.
3062 Affected file lib/silccrypt/silcpkcs.c.
3064 * Execute the packet parsing for client with zero (0) timeout
3065 if the protocol is active. Affected file silcd/server.c.
3067 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Made the key generation options to the silcd program. Added
3070 -C option, equivalent to client's option.
3072 * Added new [ServerKeys] config section to the server. It
3073 configures the server's public and private key.
3075 * Defined generic Public Key Payload into the protocol
3076 specification to send specific type of public keys and
3079 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3080 public key or certificate.
3082 * Implemented the GETKEY command to the server and to the
3083 client library and on user interface.
3085 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3087 * Made preliminary `make install' work.

3116 SilcClientConnection structure; not needed. Affected file is
3117 lib/silcclient/client.h.
3121 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Do not ask whether user wants to use the negotiated private key
3124 for private messages, just use it. Affected file is
3125 silc/local_command.c.
3127 * Added `send_enc_key' and `enc_key_len' fields to the
3128 SilcIDListData structure since they are needed in the re-key
3129 phase. Affected file is silcd/idlist.[ch].
3131 * Implemented the simple re-key protocol into the server.

3143 the PFS is to be performed in the re-key. Affected file is
3146 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3149 int64 of at least the xintXX size. If void * is less that 4
3150 bytes uint32 * will be used. Defined bool as boolean.
3152 * Changed _ALL_ unsigned long and unsigned int to uint32,
3153 unsgined short to uint16 in the source tree.
3155 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3156 not handle clients that has entry->data.registered == FALSE.
3157 They are not in the network anymore. Affected file is
3160 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Implemented the sending of the SERVER_SIGNOFF notify in the
3163 server. Affected file is silcd/server.c.
3165 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3166 Added also silc_notify_payload_encode_args into the

3170 Affected file silcd/packet_receive.c.
3172 * Implemented the SERVER_SIGNOFF notify handling in the client
3173 library. Affected file lib/silcclient/client_notify.c. Also,
3174 implemnted the printing of the SERVER_SIGNOFF info to the
3175 application. Affected file silc/client_ops.c.
3177 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3178 if the deleting was successful. Affected file silcd/idlist.[ch].
3180 * Added support for public key authentication in the connection
3181 authentication protocol in the client library. Affected file
3182 lib/silcclient/protocol.c.
3184 * Changed the server's silc_idlist_get_clients_by_* interface
3185 to support already allocated array so that new entries may be
3186 added to pre-allocated array. Affected file silcd/idlist.[ch].
3187 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3188 and command replies.
3190 * All command reply functions in the server now calls the
3191 pending command callback even if error occured. This way the
3192 error will be delivered to the client as well. Affected files
3193 silcd/command.c and silcd/command_reply.c.
3195 * Fixed INFO command to return local server's info if no server
3196 was provided. Affected file lib/silcclient/command.c.
3198 * Removed RESTART command for good. Updated the code and the

3202 Removed unsued task priorities. The affected files are
3203 lib/silcutil/silctask.[ch].
3205 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Moved the USERS printing from the library to the application.
3208 Affected files lib/silcclient/command.c and silc/client_ops.c.
3210 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Added channel key re-key support. The re-key is perfomed
3215 only by the router and is done once in an hour. Added `rekey'
3216 field to the SilcChannelEntry in the server. Affected files
3217 silcd/server.c and silcd/idlist.h.
3219 * Added silc_task_unregister_by_context into the file
3220 lib/silcutil/silctask.[ch].
3222 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added SILC_UMODE_GONE mode to indicate when the client is not
3225 present in the SILC network. Added also support to the local
3226 command AWAY that will set this mode. Added support of showing
3227 "xxx is gone" in WHOIS command. The USERS command shows the
3228 gone status as well.
3230 * Fixed setting server and router operator privileges in the
3231 server's UMODE command. Affected file silcd/command.c.
3233 * Merged the SKE KE1 and KE2 payloads into one payload. The
3234 new KE payload is equivalent to the old KE2 payload.
3236 Cleaned up the SKE Start Payload parsing. It now uses the
3237 simple buffer unformatting to do the parsing. A lot faster
3240 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3241 to the SKE that is used to indicate whether both of the SKE
3242 parties should perform authentication. By default only the
3243 responder performs authentication. By setting this flag also
3244 the initiator must do authentication. By default it is unset
3245 since in normal SKE case, client to server connection, only
3246 the responder should do authentication. When doing SKE between
3247 two clients both should perform authentication. Updated the
3248 code and the protocol specs.
3250 * A little fix to IDENTIFY command in the server. Search the
3251 client first by hash not nickname. Affected file is
3254 * Fixed the silc_client_close_connection to support closing
3255 the client to client connections wihtout deleting too much
3256 data. Affected file lib/silcclient/client.c.
3258 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3259 are received if protocol used to be active but is not anymore
3260 the application would crash due to NULL pointer dereference.
3261 Affected files silcd/server.c and lib/silcclient/client.c.
3263 * Added `hash' field to the SilcClientConnection to include
3264 the hash function negotiated in the SKE protocol.
3266 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3267 to set the channel founder authentication data. A client can
3268 claim the founder rights later by providing the authentication
3269 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3270 This way the channel founder can regain the channel founder
3271 privileges even it is left the channel. This works only on
3272 local server and the client must be connected to the same
3273 server to be able to regain the founder rights. Updated the
3274 protocol specs accordingly.
3276 Added support to the CMODE command in the client to set the
3277 founder auth data. Read the README to see how to set it.
3279 Added support to the CUMODE command to claim the founder
3280 rights. Read the README to see how to do it.
3282 Added support for the founder authentication to the Channel
3283 Entry in the server. Affected file silcd/idlist.h.
3285 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3286 server's CMODE command. Affected file silcd/command.c.
3288 * Added the following new functions into lib/silccore/silcauth.[ch]:
3289 silc_auth_get_method and silc_auth_get_data.
3291 * The server now saves the remote hosts public key to the
3292 SilcIDListData pointer. Affected file silcd/protocol.c.
3294 * The normal server now does not remove the channel entry from
3295 the cache if the founder authentication data is set. It used
3296 to remove it if the founder was the last one on the channel on
3297 the server and left the channel. The auth data is saved and
3298 if the channel is re-joined later the old entry is used with
3299 the old auth data. Affected files silcd/command_reply.c and
3302 * Removed the `pkcs' field from the SilcIDListData structure
3303 in the server; it is not used. Affected file silcd/idlist.h.
3305 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Fixed packet processing on slow links. Partial packets were
3308 never re-processed because the incoming data buffer was cleared
3309 by the application. Application must not directly clear the
3310 sock->inbuf, the packet processing routines handle it. Fixed
3311 this in client library and in server.
3313 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Fixed the WHOIS and IDENTIFY send reply function to really
3316 check whether to send list or just one entry. Affected file
3319 * Cleaned up the LEAVE command's channel key distribution. The
3320 affected file silcd/command.c.
3322 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3323 can enforce the channel mode as well. In that case the ID
3324 includes the ID of the server. The code now enforces the
3325 mode change if the router have different mode than the server.
3327 * The notify client operation with CMODE_CHANGE notify can now
3328 return NULL client_entry pointer if the CMODE was not changed
3329 by client. Application must check for this.
3331 * Added <Server ID> argument to INFO command to support server
3332 info fetching by Server ID.
3334 * Added silc_server_announce_get_channel_users to get assembled
3335 packets of channel users of the specified channel. Affected
3336 file silcd/server.[ch].
3338 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3339 was freed underneath the ID Cache.
3341 * Re-announce clients when the server received CHANNEL_CHANGE
3342 notify from the router. Affected file silcd/packet_send.c.
3344 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3347 crashed since it did not handle the fact that there is no cipher
3348 called "3" and didn't check the error condition. Now fixed.
3350 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3351 flag. It can be used to send message requests.
3353 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Implemented the RESTART command in the client.
3357 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3358 notice type messages. Added notice printing to the user
3361 * The channel keys are not re-generated if the channel's mode
3362 is PRIVKEY, ie private key on the channel exists. Affected
3363 files silcd/server.c and silcd/command.c.
3365 * Fixed a little bug in channel message delivery when channel
3366 private keys are set in the server. Affected file is
3367 silcd/packet_send.c.
3369 * Changed the setting on channel->on_channel = TRUE from the
3370 silc_client_save_channel_key to the JOIN command reply. The
3371 key payload is not received if the private channel key is set.
3372 Affected file lib/silcclient/command_reply.c and the
3373 lib/silcclient/client_channel.c.
3375 * When the CMODE_CHANGE notify is sent and the channel private
3376 key mode is removed the channel key must be re-generated in
3377 other cells as well. Added this support for the router in the
3378 silcd/packet_receive.c.
3380 * Added new local command NOTICE to send notice message on
3381 channel. Affected file silc/local_command.[ch].
3383 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Added new local command ME to the client. It is used to send
3386 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3387 some action. Affected file silc/local_command.[ch].
3389 * Changed channel_message and private_message client operations
3390 to deliver the message flags to the application. Added also
3391 the `flags' arguments to the silc_client_send_channel_message
3392 and silc_client_send_private_message functions. Affected file
3395 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Redefined the Private Message Payload to support private message
3398 keys and to support the new private message flags. Updated
3399 the protocol specs. Flags makes it possible to have for example
3400 CTCP style messages.
3402 * Added new type SilcPrivateMessagePayload and defined an API
3403 for it in the lib/silcclient/silcprivate.[ch].
3405 * Tested private message private keys successfully. Tested the
3406 private message key set, unset and list commands with the new
3409 * Redefined the Channel Message Payload to include the channel
3410 message flags (equal with private message flags) to support
3411 for example CTCP style messages.
3413 * Defined some of the message (for channel and private message)
3414 flags. Updated the protocol specs and added the flags to the
3415 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3417 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Added SilcKeyAgreementStatus type to the key agreement routines
3420 to indicate the current status and error if one occured.
3421 The status types are defined in the lib/silcclient/silcapi.h.
3423 * Added new local command KEY that is used to set and unset private
3424 keys for channels, set and unset private keys for private messages
3425 with remote clients and to send key agreement requests and
3426 negotiate the key agreement protocol with remote client. The
3427 key agreement is supported only to negotiate private message keys,
3428 it currently cannot be used to negotiate private keys for channels,
3429 as it is not convenient for that purpose.
3431 * Fixed a minor pending callback setting bug in the function
3432 silc_client_get_client_by_id_resolve, now the function works.
3433 Affected file lib/silcclient/idlist.c.
3435 * Added function silc_net_get_local_port to get local bound
3436 port by socket. Added to lib/silcutil/silcnet.[ch].
3438 * Added `sockets' and `sockets_count' fields to the SilcClient
3439 object. They hold the sockets of the listenning sockets in
3440 the client. Listenning sockets may be for example the key
3441 agreement server. Affected file lib/silcclient/client.[ch].
3442 Added functions the silc_client_add_socket and the
3443 silc_client_del_socket. They are exported to the application
3446 * Added ~./silc/clientkeys to support other client's public keys.
3448 * Renamed verify_server_key client operation to verify_public_key
3449 and added one argument to indicate the type of the connection
3450 (server, client etc.).
3452 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Added silc_server_connection_auth_request to handle the
3455 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3456 silcd/packet_receive.[ch].
3458 * Added silc_server_send_connection_auth_request into the
3459 silcd/packet_send.c to send the connection auth request packet.
3461 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3464 * Fixed the public key authentication in responder side in the
3465 server. The `auth_data' pointer includes the SilcPublicKey
3466 not the path to the public key. Affected file silcd/protocol.c.
3468 * Implemented the public key authentication in the initiator side
3469 in the server. Affected file silcd/protocol.c.
3471 * Removed the [RedirectClient] config section from the server
3472 configuration. Is not needed and I don't want to implement it.
3474 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Cleaned up the CMODE command in the server. It now works
3477 correctly and supports all the modes defined in the protocol.
3478 Affected file is silcd/command.c.
3480 * Added `hmac_name' field to the SilcChannelEntry in the server
3481 to hold the default HMAC of the channel. It can be set when
3482 creating the channel (with JOIN command). Affected files
3485 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3486 type to indicate the change of the current cipher and hmac
3487 on the channel. Client can safely ignore the <cipher> argument
3488 (if it chooses to do so) since the CHANNEL_KEY packet will
3489 force the channel key change anyway. The <hmac> argument is
3490 important since the client is responsible of setting the new
3491 HMAC and the hmac key into use.
3493 * Fixed the CMODE command in the client library as well.
3495 * Tested CMODE command in router environment successfully.
3497 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Show the version of the remote client (or server) when connecting
3500 to the server. It is logged to the log file. Affected file
3501 is silcd/protocol.c.
3503 * Fixed the KILLED notify handling in the client library. The
3504 client must be removed from all channels when receiving the
3507 Also, do not remove the client entry when giving the KILL
3508 command but when the KILLED notify is received.
3510 * Removed silc_idlist_find_client_by_nickname from the server.
3511 Not needed anymore. Affected files silcd/idlist.[ch].
3513 * Implemented the CHANNEL_CHANGE notify type handling to the
3514 server. Affected file silcd/server.c.
3518 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Added silc_server_send_notify_invite to send the INVITE
3521 notify between routers.
3523 * Implemented the INVITE command correctly to the server.

3532 * Added function silc_server_get_client_resolve to find the
3533 client entry by ID from all ID lists and then resolve it
3534 (using WHOIS) if it cannot be found. Affected file is
3537 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Implemented the BAN command to the client library.
3541 * The JOIN command in the server now checks the invite list
3544 * Changed the silc_command_reply_payload_encode_va and the
3545 silc_command_payload_encode_va to support that if argument is
3546 NULL it ignores and checks the next argument. Affected file
3547 lib/silccore/silccommand.c.
3549 * Added silc_server_send_notify_ban to send the BAN notify
3550 type between routers.
3552 * Chaned the silc_notify_payload_encode to support that if
3553 argument is NULL it ignores and checks the next argument.
3554 Affected file lib/silccore/silcnotify.c.
3556 * Tested ban lists in router environment successfully.
3558 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Implemented BAN command to the server, in silcd/command.[ch].
3562 * Removed the BAN and INVITE_LIST modes from the CMODE command
3565 * Added function silc_string_match to regex match two strings.
3566 Affected files lib/silcutil/silcutil.[ch].
3568 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Redefined parts of the SilcChannelEntry in the server to support
3571 the new ban and invite lists.
3573 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Redefined the INVITE command. The same command can be used to
3576 invite individuals to the channel but also to manage the invite
3577 list of the channel (to add to and remove from the invite list).
3578 Updated the protocol specs.
3580 * Added new command SILC_COMMAND_BAN that can be used to manage
3581 the ban list of the channel. Updated the protocol specs.
3583 * Removed the channel modes: the SILC_CMODE_BAN and the
3584 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3585 in the CMODE command. The equivalent features are now available
3586 using INVITE and BAN commands. Updated the protocol specs.
3588 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3589 in the network about change in the current ban list. The notify
3590 type is not used by the client.
3592 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3593 support the invite lists.
3595 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Added new function silc_string_regexify that converts string
3598 including wildcard characters into regex string that can
3599 be used by the GNU regex library. Added into the file
3600 lib/silcutil/silcutil.[ch].
3602 Added silc_string_regex_combine to combine to regex strings
3603 into one so that they can be used as one regex string by
3604 the GNU regex library. Added into the file
3605 lib/silcutil/silcutil.[ch].
3607 Added silc_string_regex_match to match two strings. It returns
3608 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3610 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Imported GNU regex to the soruce tree into lib/contrib.
3613 Fixed some compiler warning from the regex.c.
3615 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3623 in the server, as the `nickname' argument may be binary data
3626 * Added silc_idlist_get_channels to return all channels from
3629 * Implemented LIST command to the server. Affected file is
3632 * Implemented the LIST command to the client library and on the
3635 * Added [<user count>] argument to the LIST command reply.
3636 With private channels the user count is not shown.
3638 * Updated TODO and README.
3640 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * The client entry's data.registered must be TRUE even with
3643 global client entry on global client list. The data.registered
3644 is used to check whether the client is anymore in the network,
3645 for example with WHOWAS command so it must be valid.
3647 * Fixed the WHOWAS command in the server. It now actually works
3648 in router environment. Added function into silcd/command_reply.c
3649 silc_server_command_reply_whowas_save.
3651 * Added silc_idlist_purge function to the silcd/idlist.c
3652 to periodically purge the ID Cache.

3662 they were buggy because of the WHOWAS information.
3664 * Fixed local command MSG to handle the async resolving of
3665 the remote client properly. It used to fail the first MSG.
3666 Affected file silc/local_command.c.
3668 * Added `data_len' field to SilcIDCache context.
3670 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Update TODO. Todo in commands in the server.
3674 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3677 used by routers as broadcast packet to inform other routers
3678 about the changed user mode.
3680 Implemented the notify handling in the server. Affected file is
3681 silcd/packet_receive.c. Added the function
3682 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3684 * Added new generic Channel Payload and deprecated the New Channel
3685 Payload. The New Channel Payload is now the generic Channel
3688 * Added new argument `mode' to the silc_server_send_new_channel
3689 as it is required in the Channel Payload now.
3691 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3692 and created a new and real SilChannelPayload to represent the
3693 new generic Channel Payload. Implemented the encode/decode
3694 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3696 * Added silc_server_get_client_channel_list to return the list
3697 of channels the client has joined for WHOIS command reply.
3698 Affected file silcd/server.[ch].
3700 * Implemented the channel list sending in the WHOIS command reply
3701 in server and in the client.
3703 Implemented the channel list displaying on the user interface
3704 as well. Affected file silc/client_ops.c.
3706 * Added silc_channel_payload_parse_list to parse list of Channel
3707 Payloads. It returns SilcDList list of SilcChannelPayloads.
3708 Client for example can use this function to parse the list of
3709 channels it receives in the WHOIS command reply. The caller
3710 must free the list by calling silc_channel_payload_list_free.
3711 Affected files lib/silccore/silcchannel.[ch].
3713 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Added one new argument <user mode> to the WHOIS command reply

3732 unknown command. Affected file silcd/command.c.
3734 * All server commands now handle the command identifier the right
3735 way when sending the command reply to the client. The client can
3736 use to identify the command replies with the identifier.
3738 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added silc_server_get_client_route to resolve the route to
3741 the client indicated by the client ID. Affected file is
3744 * Added silc_server_relay_packet as general function to relay
3745 packet to arbitrary destination. This deprecates functions
3746 like _send_private_message_key, _relay_notify etc. Affected
3747 file is silcd/packet_send.[ch].
3749 Removed silc_server_send_key_agreement,
3750 silc_server_send_private_message_key and
3751 silc_server_packet_relay_notify functions from the file
3752 silcd/packet_send.[ch].
3756 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3757 server. Affected file silcd/packet_receive.[ch].
3759 * Implemented the KILL command to the client. Implemented the
3760 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3761 Affected files lib/silcclient/command[_reply].c and
3762 lib/silcclient/client_notify.c. Implemented the KILL notify
3763 printing in the user inteface.
3765 * Fixed a lot silc_parse_nick memory leaks from the client
3766 library in the file lib/silcclient/command.c.
3768 * Changed the silc_server_send_notify_on_channels's `sender'
3769 argument from SilcSocketConnection to SilcClientEntry to
3770 check the sender as entry and not as connection object and not
3771 to send to the client provided as argument. The affected file
3772 is silcd/packet_send.[ch].
3774 * The notify packets that are destined directly to the client used
3775 to not to be processed by the server. Now changed that and the
3776 server processes all notify packets. After relaying the packet
3777 to the client the notify packet is processed in the server.
3779 * The silc_server_free_client_data now checks whether there is
3780 pending outgoing traffic for the client and purges the data to
3781 the network before removing the client entry.
3783 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3786 an client is killed from the SILC Network. Updated the protocol
3789 Added new function silc_server_send_notify_killed to the
3790 silcd/packet_send.[ch].
3792 * Added function silc_server_packet_relay_notify to relay notify
3793 packets that are destined directly to a client. In this case
3794 the server does not process the notify packets but merely relays
3795 it to the client. Affected file silcd/packet_send.[ch].
3797 Added also silc_server_packet_process_relay_notify to check
3798 whereto relay the notify. Affected file is
3799 silcd/packet_receive.[ch].
3801 * Implemented the KILL command to the server.
3805 * Added the backup schema desgined last fall to the protocol
3806 specs for everyone to see. The specification is in the
3807 *-spec-xx.txt draft and the packet type definitions for the
3808 backup routers is in *-pp-xx.txt draft. Thusly, added also
3809 new packet type SILC_PACKET_CELL_ROUTERS.
3811 * A big security problem in the implementation discovered. The
3812 signoff of an client did not cause new channel key generation
3813 which it of course should've done. The channel keys must be
3814 always re-generated when client leaves (or signoffs) the channel.
3815 The silc_server_remove_from_channels funtion now handles
3816 the channel key re-generation.
3818 * Added `sender' argument to the silc_server_send_notify_on_channels
3819 to not to send the client provided as argument. Affected file
3820 silcd/packet_send.[ch].
3822 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Implemented OPER and SILCOPER commands into the server and
3827 * Added silc_auth_verify and silc_auth_verify_data to verify
3828 the authentication directly from the authentication payload.
3829 It supports verifying both passphrase and public key based
3830 authentication. Affected file lib/silccore/silcauth.[ch].
3832 * Added `hash' field to the SilcIDListData structure. It is the
3833 hash negotiated in the SKE protocol. Affected file is
3836 * Slight redesigning of the SilcAuthPayload handling routines.
3837 Do not send SilcPKCS but SilcPublicKey as argument.
3839 * Implemented the public key authentication support to the
3840 serverconfig. The public key is loaded from the provided path
3841 and saved as authentication data to void * pointer. Thus,
3842 changed the unsigned char *auth_data to void *auth_data;
3844 * Fixed SHUTDOWN command to send the reply before the server
3845 is shutdown. :) Affected file silcd/command.c.
3847 * Fixed fatal bug in CONNECT command. The hostname was invalid
3848 memory and server crashed. Affected file silcd/command.c.
3850 * Fixed fatal bug in CLOSE command. The server_entry became
3851 invalid but was referenced later in the command. Affected file
3854 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Fixed fatal bug in failure packet handling. Server ignored
3857 the failure and thus crashed when it came.
3861 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3864 that the command may be executed only once in (about) 2 seconds.
3865 The old SILC_CF_LAG flag is same but allows command bursts up
3866 to five before limiting.
3868 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3869 server code. Various commands now includes the CF_LAG_STRICT
3870 flag to disallow any kind of miss-use of the command.
3872 * Fixed the silc_buffer_unformat to not to allocate any data
3873 if the length of the data is zero. It used to allocate the
3874 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3876 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Changed the format of AdminConnection configuration section
3879 in the server. Added username of the admin to the format.
3880 Affected files silcd/serverconfig.[ch].
3882 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3883 to return admin configuration data by host, username and/or
3886 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3888 * Implemented WHOWAS command to the server. Added the functions:
3890 silc_server_command_whowas_parse,
3891 silc_server_command_whowas_send_reply,
3892 silc_server_command_whowas_from_client and
3893 silc_server_command_whowas_from_server
3895 * Added <Client ID> argument to the WHOWAS command reply. Updated
3896 the protocol specs accordingly.
3898 * Implemented WHOWAS command and command_reply to the client
3901 Implemented the WHOWAS printing on the user interface.
3903 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Added new argument to the WHOWAS command reply, the real name.
3906 It is an optional argument. Updated the protocol specs.
3908 * Added SilcIDCacheDestructor callback that is registered when
3909 the SilcIDCache is allocated. The callback is called when
3910 an cache entry in the ID Cache expires, or is purged from the
3911 cache. Added into lib/silccore/idcache.[ch].
3913 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3914 to destruct the client entries when the cache entry expires.
3915 Other ID Cache's in server and in the client library ignores
3918 * If the ID Cache entry's `expire' field is zero then the entry
3919 never expires. Added boolean `expire' argument to the
3920 silc_idcache_add function in the lib/silccore/idcache.[ch].
3921 If it is TRUE the default expiry value is used.
3923 * Added silc_server_free_client_data_timeout that is registered
3924 when client disconnects. By default for 5 minutes we preserve
3925 the client entry for history - for WHOWAS command.
3927 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Added support to the server to enforce that commands are not
3930 executed more than once in 2 seconds. If server receives
3931 commands from client more frequently, timeout is registered
3932 to process the commands. Affected file silcd/command.c.
3933 Added new function silc_server_command_process_timeout.
3935 * Changed NICK_NOTIFY handling in client library to check that
3936 if the client's nickname was changed, so there is no need to
3937 resolve anything from the server.
3939 * Removed error printing from the WHOIS and IDENTIFY commands.
3940 If error occurs then it is ignored silently in the client library.
3941 The application, however, may map the received error to
3942 human readable error string. The application currently maps
3943 the NO_SUCH_NICKNAME error to string.
3945 * Made the command status message public to the application. Moved
3946 them from lib/silcclient/command_reply.c to
3947 lib/silcclient/command_reply.h. The application can map the
3948 received command status to the string with the
3949 silc_client_command_status_message function.
3951 * Added check to the server to check that client's ID is same
3952 as the Source ID in the packet the client sent. They must
3955 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Added dist-bzip hook to the Makefile.am to make bzip2
3958 compressed distributions.
3960 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3962 * Server now enforces the maximum length for the nickname and
3963 the channel as protocol specification dictates. 128 bytes for
3964 nickname and 256 bytes for channel name.
3966 * Moved the WHOIS printing to the application. The client libary
3967 does not print out the WHOIS information anymore, the application
3968 must do it. Renamed silc_client_command_reply_whois_print to
3969 the silc_client_command_reply_whois_save.
3971 The client's idle time is also sent to the application now, and
3972 the idle is shown on screen.
3974 * Added silc_client_command_reply_identify_save to save the
3975 received IDENTIFY entries.
3977 * Do not check for channel private keys in message sending and
3978 reception if the channel does not have the PRIVKEY mode set.
3979 Affected file lib/silclient/client_channel.c.
3981 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3984 just surfaced after chaning the JOIN procedure.
3986 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Added silc_client_get_clients_by_list to get client entries
3989 from Client ID list, that is returned for example by JOIN
3990 and USERS command replies. The application should use this
3991 function for example when JOIN command reply is received to
3992 resolve the clients already on the channel (library does not
3993 do that anymore as USERS command reply is not used in the JOIN
3994 procedure anymore). Affected files lib/silcclient/silcapi.h and
3995 lib/silcclient/idlist.c.
3997 * JOIN command reply and USERS command reply returns now SilcBuffer
3998 pointers instead of unsigned char pointers when returning
3999 the client list and mode list.
4001 * Added <Client ID> argument to the JOIN command reply, mainly
4002 for the server to identify for which client the command was
4003 originally sent. Updated protocol specs accordingly.
4005 * Added SilcDlist private_key pointer to the SilcChannelEntry
4006 in the client to support the channel private keys. Affected
4007 file is lib/silcclient/idlist.h.
4009 * Added SilcChannelPrivateKey argument to the function
4010 silc_client_send_channel_message so that application can choose
4011 to use specific private ke if it wants to. If it is not provided,
4012 the normal channel key is used, unless private keys are set.
4013 In this case the first (key that was added first) is used
4014 as the encryption key.
4016 * Implemented the support for channel private key handling.
4017 Implemented the following functions:
4019 silc_client_add_channel_private_key,
4020 silc_client_del_channel_private_keys,
4021 silc_client_del_channel_private_key,
4022 silc_client_list_channel_private_keys and
4023 silc_client_free_channel_private_keys
4025 Affected file lib/silcclient/client_channel.c.
4027 * Added the support for the private keys in the channel message
4028 sending and encryption and in the message reception and
4029 decryption. Affected funtions are
4030 silc_client_send_channel_message and silc_client_channel_message.
4032 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Added SKE's key verify callback to the client library's
4035 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4037 * Removed the statement that server (or router) must send USERS
4038 command reply when joining to the channel so that the client
4039 knows who are on the channel. Instead, the client list and
4040 client's mode list is now sent in the JOIN command reply to the
4041 client who joined channel. This is better solution.
4043 * Added function silc_server_get_users_on_channel and function
4044 silc_server_save_users_on_channel to the silcd/server.[ch].
4046 * Removed function silc_server_command_send_users from the
4049 * Do not show topic on the client library anymore. The topic is
4050 sent in the command reply notify to the application and the
4051 application must show the topic now.
4053 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Added client searching by nickname hash into the IDENTIFY and
4056 WHOIS commands in the server as they were clearly missing from
4057 them. Affected file is silcd/command.c.
4059 * Fixed a bug in private message receiving in the client library.
4060 The remote ID was freed and it wasn't supposed, now it is
4063 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Minor fix to the channel payload; allocate the data area, as it
4066 needs to be of specific length.
4068 * If the key agreement port is zero then the operating
4069 system will define the bound port. Affected files are
4070 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4072 * Added new function silc_channel_payload_decrypt into the file
4073 lib/silccore/silcchannel.[ch].
4075 * Moved the channel message etc, check from silc_packet_decrypt
4076 to applications. The library calls now a generic
4077 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4078 when the packet is either normal or special. This was done to
4079 allow more wide range of checking that was not allowed when
4080 the code was in library. Now applications can do virtually any
4081 checks to the packet and return to the library the decision how
4082 the packet should be processed. Affected files are
4083 lib/silccore/silcpacket.[ch].
4085 Added silc_server_packet_decrypt_check to the server and
4086 silc_client_packet_decrypt_check to the client library.
4088 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4089 to send with specified source and destination information.
4091 * Channel message delivery between routers was broken after the
4092 channel key distribution was fixed earlier. The channel key
4093 was used be to distributed to other routers as well which is not
4094 allowed by the protocol. Now this is fixed and channel keys
4095 really are cell specific and the channel message delivery between
4096 routers comply with the protocol specification.
4098 * Fixed various commands in server to check also the global list
4099 for the channel entry and not just the local list. The affected
4100 file silcd/command.c.
4102 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added assert()s to buffer formatting and unformatting routines
4105 to assert (if --enable-debug) when error occurs. Affected
4106 file: lib/silcutil/silcbuffmt.c.
4108 * Changed to auto-reconnect to check whether the remote host is
4109 router and register the re-connect timeout if it is. It used
4110 to check that whether we are normal server, but router must do
4111 auto-reconnect with another router as well. Affected file
4114 * Removed the [<key len>] option from CMODE command as the cipher
4115 name decides the key length, nowadays. See the defined ciphers
4116 from the protocol specification.
4118 * Added [<hmac>] option to the CMODE command to define the HMAC
4119 for the channel. Added SILC_CMODE_HMAC channel mode.
4121 * Added [<hmac>] option for the JOIN command so that user can
4122 select which HMAC is used to compute the MACs of the channel
4125 * Added Hmac field to the Channel Message Payload. The integrity
4126 of plaintext channel messages are now protected by computing
4127 MAC of the message and attaching the MAC to the payload. The
4128 MAC is encrypted. Now, it is clear that this causes some
4129 overhead to the size of the packet but rationale for this is that
4130 now the receiver can verify whether the channel message decrypted
4131 correctly and also when private keys are set for the channel the
4132 receiver can decrypt the packet with several keys and check from
4133 the MAC which key decrypted the message correctly.
4135 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4136 lib/silccrypt/silccipher.[ch].
4138 * Added silc_hash_len to return the digest length into the
4139 lib/silcrypt/silchash.[ch].
4141 * Rewrote parts of Silc Channel Payload interface in the
4142 lib/silccore/silcchannel.[ch]. The encode function now also
4143 encrypts the packet and parse function decrypts it.
4145 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Fixed a minor formatting bug in the SKE's key material processing.
4148 It actually might have processed the keys wrong way resulting
4151 * Redefined the mandatory HMAC algorithms and added new algorithms.
4152 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4153 and hmac-md5 truncated to 96 bits. The mandatory is now
4154 hmac-sha1-96. Rest are optional (including the one that used
4155 to be mandatory). Rationale for this is that the truncated HMAC
4156 length is sufficient from security point of view and can actually
4157 make the attack against the HMAC harder. Also, the truncated
4158 HMAC causes less overhead to the packets. See the RFC2104 for
4161 * Added new [hmac] configuration section. The SKE used to use
4162 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4163 is of course wrong. The official names that must be proposed in
4164 the SKE are the ones defined in the protocol specification
4165 (hmac-sha1-96 for example). The user can configure any hmac
4166 using any hash function configured in the [hash] section. At
4167 least, the mandatory must be configured.
4169 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4171 * Added HMAC list to the SKE proposal list. It has now both
4172 hash algorithm list and HMAC list. This makes the protocol
4173 incompatible with previous versions. The SKE now seems to work
4174 the way it is supposed to work, for the first time actually.
4176 * Defined plain Hash algorithms to the protocol specification.
4179 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Implemented support for key agreement packets into the server.
4182 Added functions silc_server_key_agreement and
4183 silc_server_send_key_agreement. Other than these functions,
4184 server has nothing to do with this packet.
4186 * Added support for private message key packets into the server.
4187 Added functions silc_server_private_message_key and
4188 silc_server_send_private_message_key.
4192 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4193 called in the protocol's final callback instead in the END
4194 protocol state. This makes a little more sense and in the same
4195 time in client we can use the same protocol routines for normal
4196 key exchange and to key agreement packet handling as well.
4198 * Added to both client's and server's KE protocol context the
4199 SilcSKEKeyMaterial pointer to save the key material. We will
4200 bring the key material to the protocol's final callback by doing
4201 this. The final callback must free the key material.
4203 * Added SKE's packet_send callback into client's KE protocol
4204 context so that the caller can choose what packet sending function
4205 is used. This way we can use different packet sending when
4206 doing normal SKE when doing key agreement packet handling (in
4207 the key agreement packet handling we do not want to encrypt
4210 * Implemented the responder side of the key agreement routines
4211 in the client. The client can now bind to specified port and
4212 accept incoming key negotiation. The key material is passed
4213 to the application after the protocol is over.
4215 * Implemented the processing of incoming Key Agreement packet
4216 in the client. Added function silc_client_key_agreement to
4219 * Implemented the intiator side of the key agreement routines
4220 in the client. The client can now initiate key agreement with
4221 another remote client. The key material is passed to the
4222 application after the protocol is over.
4224 * Created client_keyagr.c to include all the key agreement
4227 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4228 SILC_TASK_CALLBACK except that it is not static.
4230 * Created client_notify.c and moved the Notify packet handling
4231 from the client.[ch] into that file.
4233 * Created client_prvmsg.c and moved all private message and
4234 private message key routines from the client.[ch] into that file.
4236 * Create client_channel.c and moved all channel message and
4237 channel private key routines from the client.[ch] into that file.
4239 * Changed silc_client_get_client_by_id_resolve to resolve with
4240 WHOIS command instead of IDENTIFY command, in the file
4241 lib/silclient/idlist.c.
4243 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Implemented the SKE's responder side to the Client library.
4247 * When FAILURE is received to the protocol do not trust it
4248 blindly. Register a timeout to wait whether the remote closes
4249 the connection as it should do it, only after that process the
4250 actual failure. This was changed to both client and server.
4252 * Added client_internal.h to include some of the structures
4253 there instead of client.h in lib/silcclient/.
4255 * Added function silc_task_unregister_by_callback to unregister
4256 timeouts by the callback function.
4258 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Some "Incomplete WHOIS info" errors has been appearing on the
4261 log files. Took away the entry->userinfo check from WHOIS
4262 reply sending. The entry->userinfo is now " " if client did not
4263 provide one. I thought this was fixed earlier but something
4264 is wrong still. Let's see if the error still appears.
4266 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Fixed a minor bug in the login when the channel key is
4269 re-generated in the server. It used to generate the key in
4270 wrong order and thus caused problems in the channel traffic.
4272 * Fixed a minor bug in channel key distsribution after
4273 KICK command. The key was not sent to the router even though
4276 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Added silc_ske_process_key_material_data as generic routine
4279 to process any key material as the SILC protocol dictates. The
4280 function is used by the actual SKE library but can be used by
4281 applications as well. This relates to the private message keys
4282 and the channel private keys since they must be processed the
4283 same way the normal SILC session keys. The protocol dictates
4284 this. Affected files: lib/silcske/silcske.[ch].
4286 Added also silc_ske_free_key_material to free the
4287 SilcSKEKeyMaterial structure.
4289 * Defined silc_cipher_set_key function to set the key for
4290 cipher without using the object's method function. The affected
4291 files: lib/silccrypt/silccipher.[ch].
4293 * Implemented silc silc_client_add_private_message_key,
4294 silc_client_add_private_message_key_ske,
4295 silc_client_del_private_message_key,
4296 silc_client_list_private_message_keys and
4297 silc_client_free_private_message_keys functions in the
4300 Added functions silc_client_send_private_message_key to send
4301 the Private Message Key payload and silc_client_private_message_key
4302 to handle incoming Private Message Key payload.
4304 * Added Cipher field to the Private Message Key payload to set
4305 the cipher to be used. If ignored, the default cipher defined
4306 in the SILC protocol (aes-256-cbc) is used.
4308 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Removed lib/silcclient/ops.h file.
4312 Redefined parts of the SILC Client Library API. Created new
4313 file silcapi.h that deprecates the ops.h file and defines the
4314 published Client Library API. Defined also private message key
4315 API and channel private key API into the file.
4317 This is the file that the application must include from the
4318 SILC Client Library. Other files need not be included by
4319 the application anymore.
4321 * Added new key_agreement client operation callback and also
4322 defined the Key Agreement library API for the application.
4324 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4327 is used by clients to request key negotiation between another
4328 client in the SILC network. If the negotiation is started it
4329 is performed using the SKE protocol. The result of the
4330 negotiation, the secret key material, can be used for example
4331 as private message key.
4333 Implemented the Key Agreement payload into the files
4334 lib/silccore/silauth.[ch].
4336 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Redefined ciphers for the SILC protocol. Added some new ciphers
4339 and defined the key lengths for the algorithms. Changed the
4340 code accordingly. The default key length is now 256 bits.
4342 * Fixed SKE key distribution function silc_ske_process_key_material
4343 when the key length is more than 128 bits. The default key
4344 length in SILC is now 256 bits.
4346 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4347 to indicate unsupported algorithm.
4349 * Renamed rijndael.c to aes.c and all functions as well.
4351 * Fixed a long standing channel key setting bug in client library.
4352 Weird that it has never surfaced before.
4354 * Fixed bug in channel deletion. If the entire channel is removed
4355 then it must also delete the references of the channel entry
4356 from the client's channel list as the client's channel entry and
4357 the channel's client entry share same memory.
4359 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Implemented CONNECT and SHUTDOWN commands in the client.
4363 * Implemented CLOSE command to the client.
4365 * Added the function silc_idlist_find_server_by_name into the
4366 files silcd/idlist.[ch].
4368 Added the function silc_idlist_find_server_by_conn into the
4369 files silcd/idlist.[ch].
4371 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * DIE command was renamed to SHUTDOWN. Updated the both code
4376 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4377 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4379 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4382 * Added function silc_server_create_connection function to create
4383 connection to remote router. My server implementation actually
4384 does not allow router to connect to normal server (it expects
4385 that normal server always initiates the connection to the router)
4386 so the CONNECT command is only good for connecting to another
4389 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4392 or some other client was kicked from the channel.
4394 Implemented the handling of the notify type to both client
4397 Implemented silc_server_send_notify_kicked to send the KICKED
4398 notify. It is used to send it to the server's primary router.
4400 * Implemented the KICK command into server and client.
4402 * Added `query' argument to the silc_idlist_get_client function
4403 to indicate whether to query the client from server or not if
4406 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4407 to indicate that the client is not channel founder.
4411 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Removed the rng context from SilcPacketContext structure and
4414 changed that the packet routine uses the Global RNG API.
4416 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Added support for quit message that client can "leave" on the
4419 channel when it quits the SILC. It is ditributed inside the
4420 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4422 Added silc_server_free_client_data that will take the
4423 signoff message as argument.
4425 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4427 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Updated parts of the protocol specification to keep it up
4432 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4435 payloads in one packet.
4437 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4438 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4439 use now the new List flag.
4441 * Also deprecated the following packet types: REPLACE_ID,
4442 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4444 * Added list support for Notify packet in server.
4446 * Added silc_server_send_notify_channel_change to send the
4447 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4448 the silc_server_send_replace_id.
4450 * Added silc_server_send_notify_nick_change to send the
4451 NICK_CHANGE notify type. Deprecates the function
4452 silc_server_send_replace_id.
4454 * Added silc_server_send_notify_join to send the JOIN notify type.
4455 Deprecates the function silc_server_send_new_channel_user.
4457 * Added silc_server_send_notify_leave to send LEAVE notify type.
4458 Deprecates the function silc_server_send_remove_channel_user.
4460 * Added silc_server_send_notify_cmode and
4461 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4462 types. Deprecates the silc_server_send_set_mode function.
4464 * Added SERVER_SIGNOFF notify type to indicate that server has
4465 quit. This means that all clients on the channel from that
4466 server will drop. This can be also used when netsplit happens.
4468 Deprecated REMOVE_ID packet type since it is not needed anymore
4471 Added silc_server_send_notify_server_signoff to send the
4472 SERVER_SIGNOFF notify type. Deprecates the function
4473 silc_server_send_remove_id.
4475 Added also silc_server_send_notify_signoff to send the
4476 SIGNOFF notify type.
4478 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4479 SILC protocol from this day on. Changed the protocol
4480 specification as well.
4482 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4483 notify type. It is used between routers to notify about
4484 topic changes on a channel.
4486 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4489 * Partly updated the protocol specification to comply with the
4490 changes now made. It is still though a bit outdated.
4492 * The JOIN notify type now takes one extra argument <Channel ID>.
4493 The packet used to be destined to the channel but now the
4494 JOIN type may be sent as list thus it is impossible to
4495 destine it to any specific channel. By adding this argument
4496 it is again possible.
4498 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Added CREDITS file. The CHANGES and CREDITS file will appear
4501 in the distribution as well.
4503 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4506 types in the server's silcd/packet_receive.c.
4508 * Implemented CMODE and CUMODE to work in router environment.
4510 * Fixed minor encoding and decoding buglet from the
4511 lib/silccore/silcmode.c.
4513 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4516 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4518 * Changed all SilcConfigServer* and silc_config_server* to
4519 SilcServerConfig* and silc_server_config*, respectively.
4522 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Associated the ID (client or server ID) to the Authentication
4525 Payload to avoid any possibility of forging. Updated the
4526 protocol specification and the code accordingly.
4528 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * The RSA key length is now save to the RsaKey context in the
4531 key generation process in lib/silccrypt/rsa.c. The key length
4532 is now used to figure out the maximum size of the block allowed
4533 to be encrypted/signed.
4535 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4536 is equivalent to the silc_mp_mp2bin but does not allocate any
4539 * Changed silc_mp_mp2bin API to take length argument. If it is
4540 non-zero then the buffer is allocated that large. If zero, then
4541 the size is approximated using silc_mp_sizeinbase, which however
4544 * Created Global RNG API which is global RNG that application can
4545 initialize. After initializing, any routine anywhere in the
4546 code (including library) can use RNG without allocating a new
4547 RNG object. This was done to allow this sort of use of the
4548 RNG in code that has no chance to allocate RNG object. All
4549 applications currently allocate this and many routines in the
4550 library use this. Affected file lib/silccrypt/silcrng.[ch].
4552 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4553 it to use the Global RNG API.
4555 * Defined Authentication Payload into protocol specification that
4556 is used during SILC session to authenticate entities. It is
4557 used for example by client to authenticate itself to the server
4558 to obtain server operator privileges.
4560 Implemented this payload into the lib/silccore/silcauth.[ch].
4561 Implemented also routines for public key based authentication
4562 as the new protocol specification dictates.
4564 Moved definitions of different authentication methods from
4565 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4567 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4568 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4569 silc_pkcs_verify_with_hash functions into the file
4570 lib/silccrypt/silcpkcs.[ch].
4572 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * The client entry's userinfo pointer must be always valid.
4575 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4576 will fail since it requires the userinfo. Now, the userinfo
4577 is allocated as "" if actual userinfo does not exist. Actually,
4578 it must exist and it is totally Ok to drop client connections
4579 that does not announce the userinfo. However, we will make
4580 this workaround for now.
4582 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4583 to return the remote port by socket.
4585 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4588 SILC_SERVER_PENDING_EXEC and added an new macro
4589 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4590 data or when error occurs while processing the pending command.
4592 Added new argument `destructor' into silc_server_command_pending
4593 and to the SilcServerCommandPending object. This destructor is
4594 now called after calling the pending callback or if error occurs
4595 immediately. If error occurs the actual pending callback won't
4596 be called at all - only the destructor. The destructor may be
4597 NULL if destructor is not needed.
4599 All this applies for client library code as well. Similar
4600 changes were made there as well for the pending commands.
4602 In the client, the application must now allocate the
4603 SilcClientCommandContext with the silc_client_command_alloc
4606 * Added reference counter to the SilcServerCommandContext. Added
4607 function silc_server_command_alloc and silc_server_command_dup
4610 Same type of functions added to the client library for the same
4613 * Removed the cmd_ident from IDListData away since it is now
4614 global for all connections. It is the command identifier used
4615 in command sending and with pending commands. The affected file
4618 * Added reference counter to the SilcSocketConnection objecet to
4619 indicate the usage count of the object. The object won't be
4620 freed untill the reference counter hits zero. Currently only
4621 server uses this, and client ignores it. The client must be
4622 set to use this too later. The affected files are
4623 lib/silccore/silcsockconn.[ch]. Added also the function
4624 silc_socket_dup to increase the reference counter.
4626 This was mainly added because it is possible that the socket
4627 is removed underneath of pending command or other async
4628 operation. Now it won't be free'd and proper DISCONNECTING
4629 flags, etc. can be set to avoid sending data to connection that
4630 is not valid anymore.
4632 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4633 the connection. After that it sets SILC_SET_DISCONNECTED.
4634 It is, however, possible that the socket data is not still freed.
4635 The silc_server_packet_process now checks that data is not
4636 read or written to connection that is DISCONNECTED. The socket
4637 get's freed when the reference counter hits zero.
4639 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Changed the client operation API: channel_message operation's
4642 `sender' is now the client entry of the sender, not the nickname
4643 and the `channel' is the channel entry, not the channel name.
4645 In the private_message operation the `sender' is now also the
4646 client entry of the sender not the nickname.
4648 Affected file is lib/silcclient/ops.h and all applications
4649 using the client operations.
4651 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4653 * Moved the calling of ops->connect() from connect_to_server_final
4654 into receive_new_id functin since that is the point when the
4655 client is actually allowed to send traffic to network. The
4656 affected file is lib/silcclient/client.c.
4658 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4661 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4662 (if needs broadcasting) instead of broadcasting the packets one
4663 by one which would make a burst in the network traffic.
4665 * Added `broadcast' argument to the functions in silcd/server.[ch]
4666 silc_server_create_new_channel[_with_id] to indicate whether
4667 to send New Channel packet to primary router.
4669 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Added new function into the silcd/server.[ch] files:
4672 silc_server_create_new_channel_with_id to create new channel with
4673 already existing Channel ID.
4675 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4676 lib/silccore/silcpacket.h. This packet is used t send list of
4677 Set Mode payloads inside one packet. Server uses this to set
4678 the modes for the channels and clients on those channels, that it
4679 announced to the router when it connected to it. The protocol
4680 specification has been updated accordingly.
4682 * The silc_server_new_channel did not handle the packet coming
4683 from normal server as it normally does not send that. However,
4684 when it announces its channels it does send it. Implemented
4685 the support for that.
4687 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4688 into the file lib/silccore/id.h.
4690 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Fixed memory leaks in the functions silc_idlist_del_client,
4693 silc_idlist_del_channel and silc_idlist_del_server in the file
4694 silcd/idlist.c. All of those leaked like a sieve.
4696 * Fixed some small memory leaks in the client's function
4697 silc_client_notify_by_server.
4699 * Added functions into silcd/server.c: silc_server_announce_clients,
4700 silc_server_announce_channels and silc_server_announce_server.
4701 These functions are used by normal and router server to announce
4702 to its primary router about clients, channels and servers (when
4703 router) that we own. This is done after we've connected to the
4706 These functions effectively implements the following packet types:
4707 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4708 and SILC_PACKET_NEW_ID_LIST.
4710 * Added new functions into the silcd/packet_receive.[ch]:
4711 silc_server_new_id_list, silc_server_new_channel_list and
4712 silc_server_new_channel_user_list to handle the incoming
4713 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4715 * Added support of changing Channel ID in the function
4716 silc_server_replace_id. If the server that announces a channel
4717 to the router already exists in the router (with same name but
4718 with different Channel ID), router is responsible to send
4719 Replace ID packet to the server and force the server to change
4720 the Channel ID to the one router has.
4722 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4723 client that the Channel ID has been changed by the router. The
4724 normal server sends this to the client. Client must start using
4725 the new Channel ID as the channel's ID.
4727 Implemented handling of this new type into lib/silcclient/client.c
4728 into the function silc_client_notify_by_server.
4730 * Added new function silc_idlist_replace_channel_id into the files
4731 silcd/idlist.[ch] to replace the Channel ID.
4733 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Call silc_server_command_identify_check always when processing
4736 the IDENTIFY command in silcd/command.c
4738 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4741 send keepalive packets. The packet can be sent by clients,
4742 servers and routers.
4744 Added function silc_socket_set_heartbeat into the file
4745 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4746 If not set, the heartbeat is not performed. The actual
4747 heartbeat is implemented in the low level socket connection
4748 library. However, application is responsible of actually
4751 Added silc_server_send_heartbeat to send the actual heartbeat
4752 packet into silcd/packet_send.[ch]. Server now performs
4753 keepalive with all connections.
4755 * Added silc_task_get_first function into lib/silcutil/silctask.c
4756 to return the timeout task with shortest timeout. There was a bug
4757 in task unregistration that caused problems. TODO has been
4758 updated to include that task system must be rewritten.
4760 * The client library will now resolve the client information when
4761 receiving JOIN notify from server for client that we know but
4762 have incomplete information.
4764 * Rewrote parts of silc_server_remove_from_channels and
4765 silc_server_remove_from_one_channel as they did not remove the
4766 channel in some circumstances even though they should've.
4768 * Encryption problem encountered in server:
4770 The LEAVE command used to send the Channel Key packet to the
4771 router immediately after generating it. However, the code
4772 had earlier sent Remove Channel user packet but not immediately,
4773 ie. it was put to queue. The order of packets in the router
4774 was that Channel Key packet was first and Remove Channel User
4775 packet was second, even though they were encrypted in the
4776 reverse order. For this reason, MAC check failed. Now, this
4777 is fixed by not sending the Channel Key packet immediately but
4778 putting it to queue. However, this is more fundamental problem:
4779 packets that are in queue should actually not be encrypted
4780 because packets that are sent immediately gets encrypted
4781 actually with wrong IV (and thus MAC check fails). So, packets
4782 that are in queue should be encrypted when they are sent to
4783 the wire and not when they put to the queue.
4785 However, the problem is that the current system has not been
4786 designed to work that way. Instead, the packet is encrypted
4787 as soon as possible and left to the queue. The queue is then
4788 just purged into wire. There won't be any fixes for this
4789 any time soon. So, the current semantic for packet sending
4792 o If you send packet to remote host and do not force the send
4793 (the packet will be in queue) then all subsequent packets to the
4794 same remote host must also be put to the queue. Only after the
4795 queue has been purged is it safe again to force the packet
4798 o If you send all packets immediately then it safe to send
4799 any of subsequent packets through the queue, however, after
4800 the first packet is put to queue then any subsequent packets
4801 must also be put to the queue.
4803 Follow these rules and everything works fine.
4805 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added new function silc_server_remove_clients_by_server to
4808 remove all client entries from ID list when the server connection
4809 is lost. In this case it is also important to invalidate all
4810 client entires as they hold the invalid server entry. This
4811 fixes fatal bug when server has lost connection and will reconnect
4814 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Made some sanity checks to silc_server_daemonise like to check
4817 whether the requested user and group actually exists.
4819 * Added sanity check to SKE's silc_ske_responder_finish to check
4820 that the public and private key actually is valid.
4822 * Invalidate the client's nickname when receiving Replace ID
4823 packet and the Client ID is being replaced. This means that the
4824 server will query the nickname if someone needs it (client)
4827 * Sort the ID Cache in client library when the ID Cache data
4828 has changed (needs sorting).
4830 * Do not allow for SILC client to create several connections to
4831 several servers. The client does not support windows right now
4832 and generating multiple connections causes weird behaviour.
4834 Irssi-silc client does support windows and can handle several
4835 connections without problems, see: www.irssi.org and SILC plugin.
4837 * Fixed some places where client was added to the IDList. The
4838 rule of thumb is following (in order to get everything right):
4839 If the client is directly connected local client then the
4840 `connection' argument must be set and `router' argument must be
4841 NULL to silc_idlist_add_client function. If the client is not
4842 directly connected client then the `router' argument must
4843 bet set and the `connection' argument must be NULL to the
4844 silc_idlist_add_client function.
4846 * The funtion silc_server_packet_send_local_channel actually did
4847 not check whether the client was locally connected or not. It
4848 does that now. Fixed a bug related to LEAVE command.
4850 * Fixed Remove Channel User payload parsing bug in server's
4851 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4853 * The server's silc_server_save_channel_key now checks also the
4854 global ID list for the channel as it might not be in the local
4855 list. Fixed a bug related to LEAVE command.
4857 * Is this the end of the [<unknown>] buglet that has been lurking
4858 around for a long time? A little for loop fix in server's
4859 silc_server_command_whois_parse that is used by both IDENTIFY
4860 and WHOIS command. At least, this was a clear bug and a cause
4861 of one type of [<unknown>] buglet.
4863 * WHOIS and IDENTIFY commands call the function
4864 silc_server_command_[whois/identify]_check function even if
4865 we are not router server.
4867 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Added --with-gmp configuration option. If set the GMP
4870 is always compiled in the SILC source tree. If not set then
4871 it is checked whether the system has the GMP3 installed. If
4872 it has then the GMP won't be compiled (the system's headers
4873 and library is used), if it doesn't have it then the GMP is
4874 compiled in the SILC source tree.
4876 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Changed RSA private exponent generation to what PKCS #1
4879 suggests. We try to find the smallest possible d by doing
4880 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4881 not security fix but optimization.
4883 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Added new config entry [Identity] to fork the server and run
4886 it as specific user and group. A patch from Bostik.
4888 * Imported Dotconf configuration library into lib/dotconf.
4889 This will be used to create the SILC configuration files later.
4890 It will appear in the distsribution after this commit.
4892 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4894 * A big code auditing weekend happening. Auditing code for
4895 obvious mistakes, bugs and errors. Also, removing any code
4898 Removed files for being obsolete:
4900 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4901 inline in the file lib/silcutil/silcbuffer.h)
4903 o lib/silcutil/silcbufutil.c (the header has inline versions)
4905 Changed code to fix possible error conditions:
4907 o The buffer formatting routines now check that the destination
4908 buffer really has enough space to add the data. This applies for
4909 both buffer formatting and unformatting
4910 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4911 unformatting was changed to accomodate following rules:
4912 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4913 sent to the function while XXX_*STRING will not allocate or copy
4914 the data into the buffer. Instead it sets the pointer from the
4915 buffer into the pointer sent as argument (XXX_*STRING used to
4916 require that the pointer must be allocated already). This change
4917 makes this whole thing a bit more consistent and more optimized
4918 (note that the data returned in the unformatting with XXX_*STRING
4919 must not be freed now). The routines return now -1 on error.
4921 o Tried to find all code that use buffer_format and buffer_unformat
4922 and added return value checking to prevent formatting and
4923 especially unformatting errors and possible subsequent fatal
4926 o Changed ske->x and ske->KEY to mallocated pointers in
4927 lib/silcske/silcske.h. Fixed possible data and memory leak.
4929 o Added return value checking to all *_parse* functions. Fixed
4930 many memory leaks as well.
4932 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4933 so that buffer overflows would not happen. All code now also
4934 checks the return value as it can fail.
4936 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Added reconnection support to server if the normal server looses
4939 its connection to the router (for example if router is rebooted).
4940 The server performs normal reconnection strategy implemented
4941 to the server. Affected file silcd/server.c.
4943 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added new packet type SILC_PACKET_SET_MODE that is used to
4946 distribute the information about changed modes (for clients,
4947 channels and clients channel modes) to all routers in the
4948 network. Updated the protocol specification accordingly.
4950 Added functions into silcd/packet_send.c and
4951 silcd/packet_receive.c: silc_server_send_set_mode,
4952 silc_server_set_mode.
4954 Added new files silcmode.[ch] into lib/silccore that implements
4955 the encoding and decoding of Set Mode Payload. Added new type
4956 SilcSetModePayload. Moved the definitions of different modes
4957 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4959 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Oops, a little mistake in server's connection authentication
4962 protocol. The protocol is not ended with FAILURE but with
4963 SUCCESS if the authentication is Ok. :) Affected file is
4966 * Implemented NICK_CHANGE notify handling in server in the file
4967 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4968 the local clients on the channel. After the changing nickname
4969 in router environment snhould work and the [<unknown>] nickname
4970 should appear no more.
4972 The silc_server_replace_id function that receives the Replace ID
4973 payload now sends the NICK_CHANGE notify type also in the file
4974 silcd/packet_receive.c
4976 * Changed WHOIS and IDENTIFY command to support the maximum amount
4977 of arguments defined in protocol specs (3328 arguments). This
4978 fixed a bug that caused problems when there were more than three
4981 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Added extra parameter, command identifier, to the
4984 silc_client_send_command so that explicit command identifier
4987 Changed that ID list routines uses specific command identifier
4988 when sending WHOIS/IDENTIFY requests to the server so that they
4989 can be identified when the reply comes back.
4991 Affected files lib/silcclient/command.[ch],
4992 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4994 * Added `sender' argument to silc_server_packet_send_to_channel
4995 to indicaet the sender who originally sent the packet to us
4996 that we are now re-sending. Ignored if NULL. Affected file
4997 silcd/packet_send.[ch].
4999 * Added some server statistics support in silcd/server_internal.h
5000 SilcServerStatistics structure and around the server code. Also
5001 send some nice statistics information when client is connecting
5004 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Fixed channel ID decoding in server's JOIN command reply in
5007 silcd/command_reply.c
5009 * Fixed braodcasting of replace ID payload to not to send it if
5010 we are standalone server in silcd/packet_receive.c.
5012 * Fixed all channel message sending routines to not to send
5013 packets to clients that has router set, since they are routed
5014 separately in the same function earlier. Affects file
5015 silcd/packet_send.c and all channel packet sending functions.
5017 * In USERS reply, res_argv[i] are not allocated, the table
5018 is allocated. Thus changed that free the table, not its
5021 * In server's whois_check and identify_check if the client is
5022 locally connected do not send any WHOIS commands - they are not
5025 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Fixed some minor bugs in client when sending WHOIS command. The
5028 arguments was in wrong order.
5030 * Removed statis function add_to_channel from server in
5031 silcd/command.c that was previously used with the joining but
5034 * Tested USERS command in router environment successfully with two
5035 routers, two servers and two clients.
5037 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Reorganized the USERS command and command reply in client library
5040 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5041 When the command is given by user we register a pending command
5042 callback that will reprocess the command after the reply has been
5043 received from the server. When reprocessing the packet we then
5044 display the information. Thus, the USERS information is displayed
5045 now in the command callback instead of in the command reply
5046 callback. The processing of the command is same as previously
5047 when server has sent the command reply in the JOINing process.
5049 * Added to USERS command in silcd/command_reply.c to join the client,
5050 we didn't use to know about, to the channel after we've created
5051 a client entry for it. Also, for clienet we did know already still
5052 check whether it is on the channel or not and add it if not.
5054 * Removed silc_server_command_join_notify as the function and its
5057 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Changed the client's pending command handling to the same as the
5060 server's pending command handling. It is also now possible to
5061 execute command reply functions from other command reply
5062 function as the function callbacks for commands and command
5063 replies are one and same. The pending commands are not static
5064 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5065 in client connection context. Thus, pending commands are server
5066 connection specific as it is convenient.
5068 Changed the function silc_client_command_pending and
5069 silc_client_command_pending_del and added new function
5070 silc_client_command_pending_check. Removed the
5071 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5074 * Added cmd_ident, current command identifier, to the client
5075 connection context in lib/silcclient/client.h to keep track on
5076 command identifiers used in command sending. Client's command reply
5077 function handling now supports the mandatory command identifiers.
5079 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5080 funtions in client to fully support pending command callbacks.
5082 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5083 as one of the arguments to the application in the command reply
5086 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5087 before first releasing SILC but came back. Now it is removed again
5088 and should come back nomore. The FORWARDED flag was used only
5089 by the JOINing procedure by forwarding the command packet to router.
5090 Now, the JOINing procedure has been changed to more generic (due
5091 to various router environment issues) and FORWARDED is not needed
5092 anymore for anything. The protocol specification is yet to be
5095 Now, removed silc_server_packet_forward from server and the flag
5096 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5098 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Renamed NAMES command to USERS command. The NAMES was named that
5101 due to historical reasons. Now it is renamed. Also, rewrote
5102 parts of the USERS command. The nickname list is not sent anymore
5103 by the server. Only Client ID and mode lists are sent in the USERS
5104 command. Changed this also to the protocol specification.
5106 The client now resolves the names and stuff after it receives
5107 the USERS list from the server when joining to the channel.
5109 * WHOIS and IDENTIFY commands has been changed to support multiple
5110 Client ID's per command. One can now search for multiple users
5111 in the network by sending only one WHOIS or IDENTIFY command.
5112 Changed the code and the protocol specifications.
5114 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5115 uses silc_server_command_whois_parse to parse the request. */
5117 * If normal server, do not parse the WHOIS and IDENTIFY requests
5118 before sending it to the router. Saves some time.
5120 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Fixed JOIN command on client library. Wrong number of arguments
5123 used to crash the client.
5125 * Added silc_server_channel_has_global function to check whether
5126 channel has global users or not.
5128 * Added silc_server_channel_has_local function to check whether channel
5129 has locally connected clients on the channel.
5131 * The silc_server_remove_from_one_channel now checks whether the
5132 channel has global users or not after given client was removed from
5133 the channel. It also checks whether the channel has local clients
5134 on the channel anymore. If it does not have then the channel entry
5135 is removed as it is not needed anymore.
5137 * The silc_server_notify now checks on JOIN notify whether the joining
5138 client is one of locally connected or global. If it is global then
5139 the channel has now global users on the channel and that is marked
5140 to the channel entry. Also, it now saves the global client to
5141 global list who is joining and JOINs it to the channel. This is
5142 for normal server, that is.
5144 Changed silc_server_send_notify_on_channel,
5145 silc_server_packet_relay_to_channel and
5146 silc_server_packet_send_to_channel check if we are normal server
5147 and client has router set (ie. global client) do not send the
5148 message to that client, as it is already routed to our router.
5150 * Implemented LEAVE notify type handling in silc_server_notify
5153 * Tested LEAVE command in router environment successfully. Tested
5154 with two routers, two servers and two clients.
5158 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5160 * Implemented SIGNOFF notify type handling in silc_server_notify
5163 * silc_server_remove_id now removes the client entry from all channels
5164 it has joined and thusly sends SIGNOFF notify type.
5166 * Rewrote the NAMES list generation in server by removing two excess
5167 loops. The lists are created now inside one loop.
5169 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * silc_server_remove_channel_user checks now also global list
5172 for channel and client.
5174 * silc_server_new_channel_user checks now both local and global
5175 list for channel and client. Fixed a bug in client id decoding.
5176 Used to decode wrong buffer.
5178 * silc_server_channel_message checks now both local and global
5179 list for channel entry.
5181 * Tested channel joining (hence JOIN) in router environment
5182 successfully. Tested with two routers, two servers and two
5185 * Tested channel message sending in router environment successfully.
5187 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added silc_server_save_channel_key into server.[ch] to save the
5190 received channel key in Channel Key payload processing. It is
5191 also used in JOIN command reply handling.
5193 Equivalent function silc_client_save_channel_key added into
5194 client.[ch] into client library.
5196 * Changed JOIN command reply to send information whether the channel
5197 was created or not (is existing already) and the channel key
5198 payload. Changed protocol specs accordingly.
5200 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5201 the request was sent by ID and not by nickname. Crashed on
5204 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5207 now correctly save the received data.
5209 * silc_server_free_sock_user_data now notifies routers in the
5210 network about entities leaving the network.
5212 At the same time implemented functions silc_server_remove_id
5213 and silc_server_send_remove_id to receive and send REMOVE_ID
5214 packets. The packet is used to notify routers in the network
5215 about leaving entities. The ID removed will become invalid in
5218 * Added function silc_idlist_del_server into server. Removes and
5219 free's server entry from ID list.
5221 * silc_server_private_message function now checks, if we are router,
5222 that the destination ID really is valid ID, naturally.
5224 * In router when NEW_ID packet is received (for new client) the
5225 hash of the Client ID is saved in the ID Cache but the
5226 client->nickname is set to NULL, instead of putting the hash
5229 IDENTIFY command now also checks that client->nickname must be
5230 valid. If it is not if will request the data from the server who
5231 owns the client. Added new function
5232 silc_server_command_identify_check.
5234 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5235 to set the command to already allocated Command Payload.
5237 * Tested private message sending in router environment with two
5238 routers, two servers and two clients. Fixed minor bugs and now
5241 * Fixed segfault from client's NAMES command. Used to crash if
5244 * Forwarded packets must not be routed even if it is not destined
5245 to the receiver. Changed server code comply with this.
5247 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Added `require_reverse_mapping' boolean value to ServerParams
5250 structure. If TRUE (not default) the server will require that
5251 the connecting host has fully qualified domain name.
5253 If the reverse mapping is not required and hostname could not be
5254 found the IP address is used as hostname.
5256 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Implemented version string checking to both client and server.
5259 The check is incomplete currently due to the abnormal version
5260 strings used in development version of SILC.
5262 * Changed all command functions in server to use the new
5265 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Changed char *data to unsigned char *data in ID Cache system to
5268 support binary data as ID Cache data. Changed code to support
5269 binary data in lib/silccore/idcache.c.
5271 * Renamed silc_server_packet_relay_command_reply to
5272 silc_server_command_reply as it is normal packet receiving
5273 function. Rewrote the function to accept command replys for
5274 servers and not only for clients.
5276 * Mark remote router always as registered server if we are connecting
5277 to it. Otherwise, commands sent by the router to us are ignored.
5279 * All ID List find routines now returns the ID Cache Entry pointer
5280 as well if requested.
5282 * WHOIS command works now in router environment, tested with two
5283 routers, two servers and two clients.
5285 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5286 in router environment (as it is almost equivalent to WHOIS) but
5287 hasn't been tested thoroughly. Added new functions:
5289 silc_server_command_identify_parse
5290 silc_server_command_identify_send_reply
5291 silc_server_command_identify_from_client
5292 silc_server_command_identify_from_server
5294 * Disabled route cache adding because adding two different ID's with
5295 same IP replaces the old cache entry thus giving wrong route.
5296 The entry->router->connection is always the fastest route anyway
5297 so route cache may not be needed. Of course, new routes maybe
5298 established after receiving the ID when the entry->router->connection
5299 might not be anymore the most optimal.
5301 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Add route cache for received ID for fast routing.
5305 * Added silc_server_packet_route to route received packet on router
5306 that is not destined to us.
5308 * Renamed silc_server_get_route to silc_server_route_get.
5310 * Added id_string and id_string_len fields into SilcServer to
5311 include encoded ServerID for fast comparing without excess
5312 encoding of the ID's.
5314 * Cleaned up WHOIS command on server side. Added following static
5317 silc_server_command_whois_parse
5318 silc_server_command_whois_check
5319 silc_server_command_whois_send_reply
5320 silc_server_command_whois_from_client
5321 silc_server_command_whois_from_server
5323 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5324 arguments in command replies. All command functions should be
5325 updated to use this macro.
5327 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Minor typo fixes on command reply handling on server.
5331 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added silc_server_command_add_to_channel internal routine to add
5334 the client to the channel after router has created the channel and
5335 sent command reply to the server.
5337 * Added generic silc_server_send_command to send any command from
5340 * Use static buffer with ID rendering instead of duplicating data.
5342 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Fixed a channel user mode bug when joining to a channel server gave
5345 everybody channel founder rights, oops.
5347 * We mark ourselves as the router of the incoming server connection
5348 if we are router ourselves. This way we can check in some packet
5349 sending functions whether it is locally connected server. For
5350 incoming router connections we put NULL.
5352 * For router sending packets locally means now always sending the
5353 packet cell wide; to local clients and local servers. For normal
5354 server sending packet locally means sending it to only local
5357 * Fixed the JOIN command to really work in router environment. If the
5358 channel is created it is always created by the router. Router is
5359 also responsible of making the initial joining to the channel,
5360 sending JOIN notify to the sending server and distributing
5361 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5362 does not exist server doesn't do anything else but forward the
5363 command to the router which performs everything.
5365 * Added silc_server_send_channel_key function to send the Channel Key
5368 * Added silc_server_create_channel_key to create new channel key. The
5369 channel key is now re-generated everytime someone joins or leaves
5370 a channel, as protocol dictates. Note: channel->key_len is the
5373 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5376 packet_receive.[ch] to separate packet sending and receiving
5377 routines. The server.[ch] now includes everything else including
5378 actual packet processing (writing and reading data) and other
5381 Renamed silc_server_private_message_send_internal to
5382 silc_server_send_private_message. The routine is still though
5383 used only to relay private messages as server does not send
5384 private messages itself.
5386 Renamed silc_server_new_channel to silc_server_create_new_channel
5387 and added new function sicl_server_new_channel that handles the
5388 incoming New Channel packet. Added also new sending function
5389 silc_server_send_new_channel to send New Channel Payload.
5391 * Added new function silc_server_notify to process incoming notify
5392 packet to the server/router. Server may then relay the notify
5393 to clients if needed.
5395 * Added new function silc_server_new_channel_user to process incoming
5396 New Channel User packet. Router will redistribute the packet and
5397 send JOIN notify to its local clients and locally connected servers
5398 if needed. Normal server will send JOIN notify to its local client
5399 on same channel when received this packet. Added also corresponding
5400 sending function silc_server_send_new_channel_user to sent the
5403 * Added boolean route argument to send_notif_to_channel and
5404 packet_send_to_channel functions to attempt to route the packet
5405 if it is TRUE and send only locally if it is FALSE.
5407 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * silc_server_replace_id now broadcasts the received replace ID
5410 packet if it is not broadcast packet already. The router must
5411 broadcast to inform other routers about changed ID.
5413 * Added backpointer to server's router into SilcServer context in
5414 silcd/server_internal.h.
5416 * Fixed silc_server_packet_broadcast to send correct broadcast
5419 * The channel key is now distributed to the local client as soon
5420 as it is received from the router (in router environment) so that
5421 no other packet may be sent for the channel until client has
5424 * silc_server_remove_channel_user now broadcasts the received
5425 Remove Channel User packet if it is not broadcast packet already.
5426 The router must broadcast to inform other routers about removed
5429 * Added users field into SilcPacketContext that is a reference count
5430 of the context. One can increase the reference count by calling
5431 silc_packet_context_dup which is now changed to just increase the
5432 reference count instead of duplicating the data. The reference
5433 count is decresed by calling silc_packet_context_free that will
5434 free the data after the reference count hits zero.
5436 For now on the packet context and everything allocated into it
5437 (including the raw packet from network) must be freed by calling
5438 the new silc_packet_context_free function. Added also new function
5439 silc_packet_context_alloc that must be used now to allocate the
5440 context. This also means that if a routine is asynchronous from
5441 silc_[client/server]_packet_parse_type the packet context must
5442 be duplicated by calling silc_packet_context_dup. Otherwise it
5443 gets free'd after silc_[client/server]_packet_parse_type returns.
5444 Also, one must remember that if packet is duplicated then its
5445 reference count must be decresed by calling the free function as
5446 many times as it was duplicated.
5448 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5449 from both client and server.
5451 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Made joining to a channel working in router environment.
5455 * Cleaned up JOIN command on server side and create function
5456 silc_server_command_join_channel internal routine to make the
5459 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Changed silc_command_pending list to SilcDList. Also, added
5462 `ident' field to SilcServerCommandPending structure to identify
5463 the reply and to call correct callback.
5465 Added silc_server_command_pending_check function to replace the
5466 corresnponding macro. The silc_command_pending list is not
5469 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5470 to set identifier to previously allocated Command Payload. It
5471 is used to set identifier for command when resending Command
5474 * Added silc_command_payload_encode_payload to encode Command
5475 Payload buffer from SilcCommandPayload structure.
5477 * Added silc_argument_payload_encode_payload to encode Argument
5478 payload buffer from SilcArgumentPayload structure.
5480 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Changed WHOIS command to support router connection on server side.
5483 The whois request is always sent to router unless the server is
5484 standalone server. After server has received the reply from the
5485 router will it send the reply to the client.
5487 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5488 broadcast received broadcast packet. The function is used only
5489 by router. The broadcast packet is always sent to the router's
5492 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5493 render given ID to printable string, for log files for example.
5495 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Made basic router to router connections working. At least they
5498 can now connect to each other but nothing really works the way
5499 they are supposed - yet.
5501 * Added new initiator token to RouterConnection configuration
5502 file in silcd/serverconfig.[ch]. It is used to tell whether we
5503 are the initiator to the remote router or whether we'll expect
5504 the other end to connect.
5506 * Moved registering of listener task to silc_server_init, hence
5507 the server starts listenning as soon as it is run, even if it
5508 does not have connections to other routers. Let's see how well
5511 * Changed default connection retry timeouts for more suitable in
5514 * Removed cipher and such arguments from silc_idlist_add_client
5515 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5516 Added new function silc_idlist_add_data to add the keys and stuff
5519 * Added SilcIDListData structure and added it to SilcClientEntry
5520 and SilcServerEntry as their first field in the structure. This
5521 way we can explicitly cast the ID entries to the SilcIDListData
5522 structure and get common data for the entries. In past, we had
5523 to first check what type of connection it is and then cast it to
5524 correct ID entry type. Now, we can directly cast the opaque
5525 pointer to the SilcIDListData (no matter what ID entry it actually
5526 is) and get the data needed.
5528 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5531 in some circumstances even if threre were timeout tasks, though not
5532 IO tasks, but tasks anyway. Now fixed.
5534 * Defined SilcServerConnection structure to hold connection specific
5535 stuff about directly connected servers and routers. The definition
5536 is currently in silcd/server_internal.h. I thought about having
5537 a bit more important role fro this struct but for now it is used
5538 only when connecting to other server (or router actually).
5540 * Added connecting retry support in server when connecting to
5541 router(s). The retry feature implement exponential backoff
5542 algorithm. Also, added SilcServerParams structure to hold default
5543 parameters for server. For now, it include these retry settings
5544 and are hard coded. After server is moded to be as Silc Server
5545 Library this structure will be more important.
5547 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Changed client librarys channel->clients table to SilcList and
5550 changed code accordingly.
5552 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Changed client's channel table to SilcList and changed code
5555 accordingly. Also changed SilcChannelClientEntry to include back-
5556 pointer to the channel so that client entry can use that structure
5557 as list as well and we have fast cross-reference to the channel.
5558 This change dramatically decreased the complexity of channel
5559 handling with client entry and vice versa (removed one extra
5560 loop when searching for channel entry from many functions).
5562 * Changed server->sim from table to SilcDList and changed code
5565 * NAMES command can now be used from user interface. It will show
5566 the user list on the channel, neatly.
5568 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5569 Code now saves realname of the user if it becomes available.
5571 * Renamed configure.in to configure.in.pre and made ./prepare
5572 script to automatically add correct version string to
5573 configure.in which it creates from configure.in.pre.
5575 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * NAMES command reply now shows users mode with the nickname when
5580 * Moved silc_client_ch[u]mode[_char] functions from
5581 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5582 place sucks, they are utility functions and should be in some
5585 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5587 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5590 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Added TRQ (efficient deque and list library) into lib/trq. This is
5595 a very good list library that is currently used in the SILC. Defined
5596 SilcList API over the library because I didn't like the API very
5597 much. See lib/trq/silclist.h for the API and examples of how to
5598 use the API. Fixed various places in the code to use the new
5599 SilcList API. The SilcList is meant for lists that has a structure
5600 already defined as a list. It is not suitable to add just some
5601 context to the list (in TRQ, the context is the list actually).
5603 So, I defined SilcDList that can be used for the purpose where
5604 predefined list structure does not exit. This can be used as
5605 such list. Now some context just can be added to the SilcDList.
5606 Currently this list is not used in the SILC just yet, though there
5607 are a lot places where this can replace dynamically allocated
5608 tables and I will fix these places, later, to use SilcDList.
5609 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5610 and use TRQ internally).
5612 Also fixed some annoying warning messages that the original TRQ
5613 code generated. Also minor changes to TRQ's Makefile.in.
5615 * Added support for querying by Client ID to both WHOIS and
5616 IDENTIFY commands into server, as required by the protocol.
5618 * Removed method function pointers from SilcBuffer structure. They
5619 weren't used to anything and just increased the context size for
5620 no good reason. This change also made silc_buffer_alloc and
5621 silc_buffer_free functions inline functions.
5623 * Disabled command flooding detection support until it's fixed so
5624 that it accepts commands in but does not execute them more than once
5627 * Added silc_net_localhost(), to return local hostname, into
5628 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5629 that must be initialized before calling silc_client_init.
5631 * Added new function: silc_server_send_notify_on_channels to send
5632 notify messages to all channels client has joined. It is assured
5633 that the message is sent only once per client.
5635 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5636 lib/silcutil/silcutil.[ch] as silc_format function. The new
5637 function is generic and is used by server as well, not only by
5638 the logging routines.
5640 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5641 the provided version string was not acceptable. Added new function:
5642 silc_ske_check_version into lib/silcske/silcske.h. The function
5643 must be implemented by the application (client or server) and it
5644 does not reside in the SKE library. The function checks the version
5645 string remote end sent.
5647 * Added back pointers (to opaque context and to SilcSocketConnection)
5648 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5650 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5651 duplicate packet context structure.
5653 * Changed `notify' client operation to send same arguments as client
5654 receives from server except for ID's. ID's are mapped to correct
5655 ID entry and that is returned. Also, if channel entry is not sent
5656 by server but the notify is for channel the channel entry is sent
5657 to application (otherwise application doesn't know that it is for
5658 channel (library gets it from packet's Destination ID)).
5660 * Added silc_client_remove_from_channels into client library to
5661 remove a client from all channels it has joined to. Used when
5662 received SIGNOFF notify from server. Added also new function
5663 silc_client_replace_from_channels to replace old ID entry with
5664 new ID entry on all channels. Used when received NICK_CHANGE
5667 * Fixed ID Cache list handling in silc_idlist_get_client in
5668 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5669 to get (or query) client by ID.
5671 * Updated TODO list.
5673 * Added connection authentication status message defined by the
5674 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5675 support for these into the code in client and server side.
5677 * Added generic function silc_client_send_command to send any command
5678 with variable argument list. Application should use this function
5679 to send commands if the command functions provided by the library
5680 does not suite for the application's user interface needs.
5682 * Added new `failure' client operation. Application is notified about
5683 received failure packet if client is executing a protocol. In this
5684 case the protocol's execution has failed.
5686 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5687 is required by the protocol.
5689 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5690 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5693 * Added status flag to SilcSKE object to indicate realtime status
5694 of the SKE protocol.
5696 * Application receives now exactly same command reply arguments as
5697 the library receives from server. However, if ID is received the
5698 corresponding ID entry is returned to the application (eg. Client
5699 ID is mapped to correct SilcClientEntry entry and that is returned).
5700 Changed command_reply client operation due to this change.
5702 * Changed all ID's in commands and in command replys as ID Payloads.
5703 Change affected both client and server side codes.
5705 All ID's sent in SILC network (with execption of ID's in SILC
5706 Packet header) are sent in ID Payload to support variable length
5709 * Server now notifies nick changes and notifies all clients on
5710 the channels about the new nickname (about the new Client ID,
5713 * Implemented CMODE command to change channel modes. Supports all
5714 channel modes defined by the protocol specs except ban and invite
5715 lists. (Also, private channel key mode is supported but support for
5716 setting private channel key in client is missing, thus, this mode
5717 has no effect on client side (except that server requires that the
5718 client uses private channel key and normal channel traffic does not
5721 Also, invite mode works per se, but INVITE command does not work
5722 yet correctly, so you can set channel as invite only channel but
5723 inviting clients to the channel does not work (it is yet to be
5724 thought what's the best way to do it).
5726 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5727 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5728 Implemented CUMODE command to change user's mode on the channel.
5729 Supports all modes defined by the protocol specs.
5731 * Added NAMES command reply to return users modes on the channel.
5733 * Removed unnecessary and slow ciphers from lib/silccrypt.
5735 * Set SO_KEEPALIVE option to connection sockets by default.
5737 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5739 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5740 redefined the Notify Payload into protocol specs.
5742 * Added silc_id_payload_parse_id to get ID directly from raw
5745 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5748 accept searching by Client ID as well.
5750 * Added support for LEAVE and SIGNOFF notify types in client library.
5752 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5753 to parse ID Payload from raw data.
5755 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added flags parameter into silc_ske_assemble_security_properties
5758 function in lib/silcske/silcske.[ch].
5760 * Changed notify client operation to fit better for notify messages
5761 sent by server. The notify payload received from server is now
5762 passed to the application (after parsing it to SilcNotifyPayload).
5763 It is application's responsibility to retrieve the arguments
5764 from the payload and show the message the way it wants. The message
5765 sent by server is implementation specific.
5767 * Changed public keys to comply with the protocol specification.
5768 Old public keys are not supported anymore and are not compatible.
5770 * Removed nickname from Channel Payload as the latest draft removed
5771 it. The client must resolve the nickname from the NAMES command
5772 reply received when it joined the channel.
5774 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5776 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Fixed some errors in protocol specification drafts.
5780 * Created lib/silccore/silcnotify.c to implement Notify Payload
5781 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5782 generic payloads described by protocol specifications. The file
5783 includes implementations for ID Payload and Argument Payload.
5785 * Changed Command Payload implementation to use the new Argument
5786 Payload. Changed command_xxxx_payload to command_payload_xxxx
5787 to comply with SILC coding conventions.
5789 * Added suppport for Argument Payload handling in Notify Payload
5790 implementation as protocol requires it. Added the new support
5791 into server and client lib as well.
5793 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Added support for multiple nicknames on same channel. [n] is
5796 added locally to the nickname if there are more than one same
5797 nicknames on the channel.
5799 * Server now sends all nicknames that matched WHOIS request.
5800 Client also shows the list received from server.
5802 * Added TOPIC command to client side. User can now set and show
5803 current topic on channel.
5805 * Added MOTD command to client and server. Also, server sends the
5806 motd when client connects to the server.
5808 * Changed version strings to comply ISO 8601.
5810 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Fixed protocol error handling in client library. It should now
5813 cope even if the SKE fails for some reason.
5815 * Made new protocol specification drafts for submitting to IETF.
5817 * Implemented TOPIC command to server in silcd/command.c.
5819 * Added two new notify types into lib/silccore/silcnotify.h:
5820 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5821 notify nickname change and topic setting/change on a channel.
5823 * API change of command_reply operation in client library. The
5824 application gets now the status type received from server as well.
5826 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5830 * Cras fixed and optimized the packet handling even further and
5831 it should work now. Minor change to the prototype of function
5832 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5834 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Added new function into lib/silcutil/silcschedule.[ch]:
5837 silc_schedule_with_fd to select() a specified fd. The function
5838 returns after timeout expires or data arrives or goes. The
5839 function is used by packet routines to wait that all data is
5840 received from network.
5842 * Fixed data reading from network in lib/silccore/silcpacket.c.
5843 The code now assures that all data is read from the fd and then
5844 continues packet processing. This was a bug fix since the code
5845 used to drop some data in some circumstances.
5847 * Added new function into lib/silcclient/client.[ch]:
5848 silc_client_start_key_exchange to start key exchange after
5849 connection has been established to server. The code internally
5850 now uses this funtion but its main purpose was to provide it
5851 for applications that perform their own connecting. After
5852 application has created a connection it merely calls this
5853 function to start the key exchange between client and server.
5854 The library takes care of everything else after that.
5856 Updated also lib/silcclient/README to explain the usage of
5859 * Do not send to application information that connection has
5860 been established. Application gets notified it by connect
5863 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Applied cras's patch to add silc_schedule_one function. The
5866 function runs scheduler once and returns.
5868 * Fixed the scheduler after cras messed it up. The timeout
5869 handling works now as it's supposed to work.
5871 * Added into lib/silccore/ silcnotify.h to include notify
5872 message types support. Changed silc_server_send_notify*
5873 functions, in server.[ch], to support those new notify types.
5874 Added the support for the notify types into client library,
5875 as well. Added new notify client operation into ops.h in
5878 * Changed silc_server_packet_send_to_channel to send normal
5879 packets instead of just channel message packets. The function
5880 is now used to send the notify packets to channels. It is not
5881 used to send channel message packets anymore, as server never
5884 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5885 va_arg()s as it seems to require it nowadays. I guess, if SILC
5886 is compiled with older va_arg() the new code should work anyway.
5888 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Splitted core library. Core library (lib/silccore) includes
5891 now only SILC protocol specific core (and common) components.
5892 Created new utility library (lib/silcutil) that includes more
5893 generic purpose stuff. The stuff for util library was taken
5894 from the old core library. This was minor and easy split.
5896 * Created SILC Client Library (lib/silcclient) that includes
5897 implementation of the SILC client without user interface. This
5898 was major move from silc/ directory. The code has been changed
5899 so that it is transparent towards the user interface. The
5900 silc/ directory includes now the same user interface as before
5901 and it uses the new client library. Read lib/silcclient/README.
5902 Basicly, the client library performs everything else related
5903 to SILC except user interface handling. Also, configuration
5904 files are considered to be part of user interface and library
5905 does not handle them.
5907 This change also changed a lot of structures, function naming etc.
5908 Most important change was that SilcClientWindow object was
5909 renamed to SilcClientConnection in the client library. Created
5910 also new file lib/silcclient/ops.h. Also added new files
5911 silc/local_command.[ch] and silc/client_ops.[ch].
5913 All these changes were made to make it easier for user interface
5914 designers to create what ever user interface for the SILC client
5917 It is also expected that the server will be moved to lib
5918 directory as well and SILC Server Library will be created;
5919 sometimes in the future.
5921 * Removed Local commands from lib/silccore/silccommand.h as
5922 they are application specific and new client library does not
5923 handle any of those anymore.
5925 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5926 old client implementation in silc/.
5928 * Added support for callback functions in SILC_LOG_* macros.
5929 Application can now set its own callbacks that will be called
5930 instead of using the default functions that will always print
5931 the debug messages to stderr (or stdout). Also, debugging can
5932 now be disabled by setting silc_debug to FALSE and re-enabled by
5933 setting it to TRUE. Note, that logging will still work even
5934 if debugging is disabled.
5936 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5937 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5938 silc_log_reset_debug_callbacks.
5940 * To enable debugging in silc client one must give now -d
5941 option on command line.
5943 * Changed silc_schedule_init to automatically allocate task queues
5944 if they are not allocated before calling it.
5946 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Added GMP 3.1 into math library.
5950 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5953 a channel in SILC network. The packet is used by servers and
5954 routers to notify other routers that user has left a channel.
5955 This little feature was missing until now. Added the feature
5956 to protocol specification as well.
5958 Added functions: silc_server_send_remove_channel_user and
5959 silc_server_remove_channel_user into server.[ch].
5961 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5962 lib/silccore/silcpacket.h. However, they are not implemented
5965 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Fixed joining to a channel and sending channel messages
5968 between server and router. The channel message sending should
5969 now work inside a cell.
5971 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Fixed the private message sending between server and router.
5974 The private message sending should now work inside a cell.
5976 * Added silc_server_replace_id into server.[ch] to replace
5977 existing ID in the SILC network.
5979 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5980 and silc_idlist_replace_server_id into idlist.[ch] in server.
5982 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Fixed the server to server connections. Server can again now
5985 connect to router. Router to router connections probably does
5988 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added dynamic protocol registering support. Now protocols can
5991 registered and unregistered on the fly. Patch by cras.
5993 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Added lib/contrib directory to hold routines that some platforms
5996 don't have but are needed by SILC.
5998 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5999 into lin/contrib to provide getopt() and getopt_long() for
6000 those who don't have it.
6002 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Added AWAY command to client. When away message is set and
6005 client receives a private message packet the client automatically
6006 replies to the sender with the away message.
6008 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6009 bug seemed to be the cause of recent problems when compiling
6012 * Added version detection support to SKE protocol specification
6013 and added the new changes to the SKE implementation as well.
6014 There were other minor changes in the SKE protocol as well.
6016 Many changes in lib/silcske/silcske.[ch] and in
6017 lib/silcske/payload.[ch].
6019 * Added ^U functionality, clear input line. Patch from cras.
6021 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Mainly small bugfixes on core library. Fixed some debugging
6024 logging and buffer overflow in silclog.c.
6026 * Updated config.sub and config.guess on the distribution tree.
6028 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Added command lagging support in server. Client may execute
6031 commands now only once in two seconds.
6033 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Optimized packet reception. MAC computation and checking is now
6036 also more optimized. A lot previously duplicated code is now
6037 used as generic by both client and server.
6039 * Fixed key pair generation in clientutil.c
6041 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added into lib/silccore/silcbufutil.[ch] new function;
6044 silc_buffer_realloc.
6046 * Moved generic packet sending/encryption functions to
6047 lib/silccore/silcpacket.[ch] from client and server. Some
6048 rewriting of the functions.
6050 * Moved all generic packet reception/decryption functions to
6051 lib/silccore/silcpacket.[ch] from client and server. The
6052 packet processing is now much cleaner in both client and server.
6053 These were major changes in both client and server.
6055 * Created many common functions in server to do packet sending.
6056 Previously code were duplicated a lot, this has been removed
6059 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Rewrote major parts of the ID cache system. Don't know
6062 whether it is better now or not but at least the API is more
6065 * Major rewrite on ID cache stuff on client because of the ID
6066 cache API changes. Added idlist.c to client.
6068 * Also major rewrite on ID cache stuff on server as well.
6069 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6070 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6071 in hand, instead they are all put into the ID cache system now.
6072 All server_idlist_* routines uses ID cache now instead of
6073 traversing its own lists (those lists does not exist anymore).
6074 SilcIDList though still exists. Also, SilcXXXEntry's are
6077 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Finally made the SKE implementation compliant to the protocol
6080 specification. All mp integers are now binary encoded as
6081 opposed being HEX encoded.
6083 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6086 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6087 functions: silc_[encode/decode]_pem. Also added function
6088 silc_encode_pem_file to PEM encode with newlines ('\n') for
6091 * SILC public keys are now encoded either PEM or binary. Same
6092 option is for private keys as well. By default private keys
6093 are binary encoded and public keys PEM encoded. Silly HEX
6094 encoding were removed.
6096 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6097 function to create fingerprints.
6099 * Fixed a bug in SHA1; does not change the original data anymore.
6101 * Partly implemented INFO command on client and server side.
6102 Fixed CLEAR command. Changes to SERVER command; show current
6103 server(s) when giving command without arguments. Added
6104 VERSION command to client.
6106 * Added check to server that unregistered connections cannot
6107 execute commands (unless it is specificly allowed).
6109 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Fixed screen refresh.
6113 * Fixed channel joining bug from client. On some circumstances
6114 client tried to join to a channel it had already joined.
6116 * Added public key verification process into client's protocol.c.
6117 The client now verifies the public key from user and saves
6118 it into ~./silc/serverkeys/ directory.
6120 Added into: clientutil.[ch]: silc_client_verify_server_key.
6122 * Changed SKE protocol's silc_ske_initiator_finish function
6123 to accept callback function that verifies the received public
6124 key. Removed old silc_ske_verify_public_key function.
6126 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6129 silc_pkcs_private_key[_data]_set.
6131 * Made the password and public authentication more cleaner in
6132 server's protocol.c.
6134 * Removed historic and obsolete protocol `channel_auth' from
6135 both client and server.
6137 * Removed wrong way of sending command status messages from
6138 server to client in server's command.c. The old way violated
6139 protocol specification.
6141 Changes to silccore/silccommand.[ch]: removed
6142 silc_command_encode_status_payload -> not needed anymore,
6143 changed silc_command_encode_payload_va to accept extra
6144 argument on variable argument list. The argument type must
6145 now be provided to the function. Also, added new function:
6146 silc_command_encode_reply_payload_va which is same as
6147 normal command_encode_payload_va except command status type
6148 is provided as extra argument.
6150 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added ~./silc directory handling. The directory includes the
6153 public and private keys for the client.
6155 Added silc_client_check_silc_dir, silc_client_create_identifier
6156 and silc_client_load_keys.
6158 * Implemented SILC protocol compliant public key. Added public
6159 and private key saving to and loading from files.
6161 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6162 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6163 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6164 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6165 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6167 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6168 silc_pkcs_load_[public/private]_key.
6170 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Added silc_server_get_route (route.[ch]) to get connection
6173 data for the fastest route for given ID.
6175 * Implemented INVITE command on client and server. The command
6176 were re-defined in the SILC Protocol Specification and the
6177 implementation now complies with the specification.
6179 * Implemented PING command on client and server.
6181 * Implemented NAMES command on client and server. The server side
6182 supports currently only normal server not router server yet.
6183 Some changes to NAMES definition in SILC protocol specification.
6185 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Implemented LEAVE command on client and server.
6189 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6190 again. This change was made to the protocol as well. Server
6191 should not violate the protocol specification anymore.
6193 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6196 was tested. SOCKS4 was not but should work anyway.
