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

118 to run server on foreground. A patch by debolaz.
119 Affected files silcd/server.c, silcd/silcd.c.
121 * Fixed MOTD to return the MOTD file server name. Affected
122 file silcd/command.c.
124 * Added INFO command reply handling to the Irssi SILC Client.
125 Affected file irssi/src/silc/core/client_ops.c.
127 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
129 * Fixed the silc_idcache_list_* routines to really support
130 the dynamic list. Fixes a crash. Affected file is
131 lib/silccore/silcidcache.c.
133 * Fixed the LIST command reply to really call LIST command's
134 pending callbacks. Affected file silcd/command_reply.c.
136 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
138 * Update conn->local_entry->nickname after giving NICK
139 command. Affected file lib/silcclient/command.c.
141 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
143 * Added the [pid] option to the silcd configuration file
145 Affected files: serverconfig.[ch] and silcd.c
147 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
149 * Save fingerprint in WHOIS command reply in server.
150 Affected file silcd/command_reply.c.
152 * Fixed NICK commands pending callback registration.
153 Affected file lib/silcclient/command.c.
155 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Use ++server->cmd_ident when sending commands in server,
158 instead of random number. Affected file silcd/command.c.
160 * Fixed GETKEY command reply to call actually GETKEY pending
161 command callbacks. Affected file silcd/command_reply.c.
163 * A bit stricter check for nicknames. Check for same nickname
164 in NICK command also. Affected file silcd/command.c.
166 * Do not call INFO command everytime client ID changes, only
167 during first connecting. Affected file lib/silcclient/client.c.
169 * Set the new nickname only after successful command reply for
170 NICK command is returned by server. Affected file
171 lib/silcclient/command.c.
173 * Remove nicknames from nicklist during server_signoff notify.
174 Should fix /NAMES bit more. The affected file is
175 irssi/src/silc/core/silc-channels.c.
177 * Added `fingerprint' field to the SilcIDListData in the
178 silcd/idlist.h to hold the fingerprint of the client's
181 Send the fingerprint of the client's public key in WHOIS
184 Affected files silcd/command.c, and silcd/idlist.[ch].
186 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
187 create fingerprint from given data.
189 * Show the fingerprint of the client's public key in WHOIS.
190 Affected files irssi/src/module-formats.[ch] and
191 irssi/src/silc/core/client_ops.c.
193 * Format the multiple same nicknames also during JOIN and
194 NICK_CHANGE notifys. Affected file is
195 lib/silcclient/client_notify.c.
197 * Do not print error on screen for invalid private message
198 payload since it can come if someone is sending private
199 messages with wrong key. Affected file
200 lib/silccore/silcprivate.c.
202 * Fixed multiple concurrent /PING crash. Affected file
203 lib/silcclient/command.c.
205 * Changed the wrong ID encoding. All IP addresses must be
206 in MSB first order in encoded format. They were encoded
207 wrong and was in LSB format. Affected files are
208 silcd/serverid.c, lib/silcutil/silcutil.c.
210 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
212 * Call the `connect' client operation through the scheduler
213 in case of error. Affected file lib/silcclient/client.c.
215 * Call the `failure' client operation even if the error
216 occurred locally during a protocol. Affected file is
217 lib/silcclient/protocol.c.
219 * Added support of sending LIST command to router from normal
220 server. This way normal server can get list of all channels
221 in the network too. Fixed the channel list sending in the
222 server too. Affected files are silcd/command.c, and
223 silcd/command_reply.[ch].
225 * Added silc_server_update_channels_by_server and
226 silc_server_remove_channels_by_server. They are used during
227 disconnection of primary router and in backup router protocol.
228 Affected file silcd/server_util.[ch], silcd/server.c and
229 silcd/server_backup.c.
231 * Fixed channel adding to global list in IDENTIFY command
232 reply in server. Affected file silcd/command_reply.c.
234 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
236 * If the incoming packet type is REKEY or REKEY_DONE process
237 that packet always synchronously. Fixes yet another MAC
238 failed error on slow (dialup) connections. Affected file
239 lib/silcclient/client.c and silcd/server.c.
241 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Call check_version SKE callback for initiator too. Affected
244 file lib/silcske/silcske.c.
246 * Implemented fix for security hole found in the SKE that was
247 fixed in the specification few days back; the initiator's
248 public key is now added to the HASH value computation.
249 Added backwards support for the old way of doing it too, for
250 old clients and old servers. Affected file is
251 lib/silcske/silcske.c.
253 * Enabled mutual authentication by default in SKE. If initiator
254 is not providing mutual authentication the responder will
255 force it. This will provide the proof of posession of the
256 private key for responder. The affected files are
257 lib/silcclient/protocol.c and silcd/protocol.c.
259 * Do not cache anymore the server's public key during SKE.
260 We do mutual authentication so the proof of posession of
261 private key is done, and if the server is authenticated in
262 conn auth protocol with public key we must have the public
263 key already. Affected file silcd/protocol.c.
265 * Added new global debug variable: silc_debug_hexdump. If
266 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
267 file lib/silcutil/silclog.[ch].
269 * Fixed compilation warning due to char * -> const char *.
270 Affected files lib/silcutil/silcnet.h, and
271 lib/silccore/silcauth.[ch].
273 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
275 * Fixed CMODE command when new channel key was created. If
276 the creation failed the old key was removed. Next time giving
277 same command would crash the server since the old key was
278 freed already. Affected file silcd/command.c.
280 * Fixed the silc_server_announce_get_channels to not crash
281 on reconnect. Affected file silcd/server.c.
283 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
285 * Added silc_log_set_debug_string function to set a regex
286 string to match for debug output. Only the function names,
287 or filenames matching the given debug string is actually
288 printed. This way it is possible to filter out those debug
289 strings that user is not interested in.
291 Fixed a bug in silc_string_regexify.
293 Affected files lib/silcutil/silclog.[ch], and
294 lib/silcutil/unix/silcunixutil.c.
296 * Changed the -d options in both server and Irssi SILC client
297 to take the debug string as argument. Affected files
298 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
300 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
302 * Added silc_hash_babbleprint to create a Bubble Babble
303 Encoded fingerprint. The encoding is developed by Antti
304 Huima (draft-huima-babble-01.txt), and it creates human
305 readable strings out of binary data. Affected file
306 lib/silccrypt/silchash.[ch].
308 * Print the babble print now in addition of fingerprint as well
309 in Irssi SILC client. Affected files are
310 irssi/src/fe-common/silc/module-formats.[ch],
311 irssi/src/fe-common/silc/core/client_ops.c.
313 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
315 * Fixed a security problem found in SKE. The initiator's
316 public key too is now added to the HASH hash value creation
317 which is signed by the responder to create the SIGN value.
318 This will prevent anyone in the middle to lie to the responder
319 about the initiator's public key. If this is done now, the
320 man in the middle will get caught. Updated the protocol
323 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
325 * Better installation directory handling. Configure module
326 paths and other paths automatically to example_silc* files
327 in doc/. A patch by toma.
329 * Fixed compiler warning from MPI library, and from SILC RNG.
332 * Added SILC_SERVER_PID_FILE to define the pid file for server.
333 It can be configured with ./configure. A patch by toma.
335 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Find correct make to use in prepare-clean. A patch by
338 toma. Affected file prepare-clean.
340 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
342 * Added irssi variables use_auto_addr, auto_bind_ip,
343 auto_bind_port and auto_public_ip.
345 * Changed the interface for silc_client_send_key_agreement
346 in lib/silcclient/silcapi.h
350 irssi/src/silc/core/silc-core.c
352 lib/silcclient/silcapi.h
353 irssi/src/silc/core/silc-channels.c
354 lib/silcclient/client_keyagr.c
357 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
359 * Added silc_pkcs_public_key_compare to compare two
360 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
362 * Check that the client who set the founder mode on the
363 channel is the same client that is giving the founder
364 mode to itself. It is done by comparing the saved public
365 key (it is saved even in the authentication is passphrase).
366 Affected file silcd/command.c.
368 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
370 * Do not process packet for disconnected socket connection.
371 Affected file lib/silccore/silcpacket.c.
373 * Process the DISCONNECT packet through scheduler in the
374 client library. Affected file lib/silcclient/client.c.
376 * Fixed the silc_client_packet_parse to not to increase
377 the packet sequence number if the conn->sock and the
378 current socket connection is not same. This can happen
379 for example during key agreement when the conn includes
380 multiple socket connections (listeners). Affected file
381 lib/silcclient/client.c.
383 * The sender of the file transfer request now provides also
384 the pointer (listener) for the key exchange protocol. If
385 the listener cannot be created then it sends empty key
386 agreement and lets the receiver provide the listener.
388 Added `local_ip' and `local_port' arguments to the
389 silc_client_file_send. If they are provided they are used,
390 if not then it will attempt to find local IP address, if
391 not found or bind fails then the remote client will provide
394 Affected files are lib/silcclient/client_ftp.c and
395 lib/silcclient/silcapi.h.
397 * Extended the FILE SEND command to support defining the
398 local IP and port for key exchange listener. They are
399 optional. Affected file irssi/src/silc/core/silc-servers.c.
401 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
403 * Defined to WHOIS command reply the sending of fingerprint
404 of the client's public key (if the proof of posession of the
405 corresponding private key is verified by the server).
406 Updated to the protocol specification.
408 * Added support of receiving the client's public key's
409 fingerprint in command reply in client library. Affected
410 file is lib/silcclient/command_reply.c, and
411 lib/silcclient/idlist.[ch].
413 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
415 * Do not send over 128 chars long nickname to the server
416 in NICK command. Affected file lib/silcclient/command.c.
418 * Do not send over 256 chars long channel names to the server
419 in JOIN command. Affected file lib/silcclient/command.c.
421 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
423 * Assure that silc_server_close_connection cannot be called
424 twice for same socket context. Affected file is
427 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
429 * Send error message to application if opening file for
430 writing during file transfer fails. Affected file is
431 lib/silcclient/client_ftp.c.
433 Remove all file transfer sessions for a client that we're
434 removing from ID cache.
436 Affected file is lib/silcclient/client_ftp.c.
438 * Fixed silc_net_addr2bin to return correct address. Affected
439 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
441 * Fixed file transfer session removing on signoff notify.
442 Affected file irssi/src/silc/core/silc-servers.c.
444 * Added the SilcClientFileError to be returned in the monitor
445 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
446 Affected file lib/silcclient/silcapi.h.
448 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
450 * Fixed a crash in silc_client_ftp_free_sessions and
451 silc_client_ftp_session_free_client. Affected file
452 lib/silcclient/client_ftp.c.
454 * Added `disabled' field in the SilcChannelEntry in the server
455 to indicate if the server entry is disabled. Affected file
456 silcd/idlist.h, silcd/command[_reply].c.
458 * SILC server adds now /var/run/silcd.pid everytime it is
459 started. Affected file silcd/silcd.c.
461 * Added silc_server_packet_send_clients to send a packet to
462 the provided table of client entries. Affected file
463 silcd/packet_send.[ch].
465 * Fixed a crash in client resolving in client_prvmsg.c in
466 client library. Affected file lib/silcclient/client_prvmsg.c.
468 * Do not actually remove the client directly from ID cache
469 during SERVER_SIGNOFF, but invalidate it. This way we
470 preserve the WHOWAS info for the client. Affected file
473 * Fixed SERVER_SIGNOFF notify handling in the server. The
474 server is now able to process incoming SERVER_SIGNOFF notify
475 for a server that it doesn't even know about. It will remove
476 the clients provided in the notify. Affected file
477 silcd/packet_receive.c.
479 * Check for partial packet in data queue after every packet that
480 was found from the queue. Return and wait for more data if
481 there is partial data in queue. Affected file is
482 lib/silccore/silcpacket.c.
484 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
486 * Added SilcClietFileError enum to indicate error in
487 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
488 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
489 Affected files lib/silcclient/silcapi.h and
490 lib/silcclient/client_ftp.c.
492 * Check that newsize in silc_buffer_realloc is larger than
493 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
495 * Added better monitor of file transfers. It now monitors
496 key agreement protocol during the file transfer too. Added
497 error reporting too. Affected files
498 irssi/src/silc/core/silc-servers.c,
499 irssi/src/fe-common/silc/module-formats.[ch].
501 * Wrote a help file for FILE command.
503 * Added silc_rng_global_get_byte_fast to get not-so-secure
504 random data as fast as possible. Random data is read from
505 /dev/urandom if available and from the SILC RNG if not
506 available. It is used in padding generation. Affected file
507 lib/silccrypt/silcrng.[ch].
509 * All packets in client library are now processed synchronously.
510 Optimized packet processing a lot. Affected file
511 lib/silcclient/client.c.
513 * All server connection packets are processing synchronously
514 now in server, to optimize packet processing. Affected file
517 * Include files are installed now only in Toolkit distribution
518 if make install is given. Affected files: all Makefile.am's.
520 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
522 * Assure that silc_client_notify_by_server_resolve does not
523 resolve the client information multiple times. If it cannot
524 be found by the first it cannot be found at all. Affected
525 file lib/silcclient/client_notify.c.
527 * Fixed WHOWAS command reply calling. Affected file
528 lib/silcclient/command_reply.c.
530 * Removed all references to silc_idlist_get_client from the
531 Irssi SILC client since that call is internal call used by
532 the library. The Irssi SILC client will use now client
533 retrieval functions found in silcapi.h.
535 * Fixed a bug in resolving nickname info before sending
536 private message. It used freed memory. Affected file
537 irssi/src/silc/core/silc-servers.c.
539 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
541 * Assure my_channels statistics cannot go negative in server.
542 Affected files silcd/server.c, silcd/server_util.c.
544 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
548 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Win32 Toolkit changes. Affected files
551 win32/silc.dsw, win32/libsilc/libsilc.def,
552 win32/libsilcclient/libsilc.def,
553 lib/silcutil/silcutil.c, and
554 lib/sftp/sftp_fs_memory.c.
556 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
558 * Added silc_net_localip to return local host's IP address.
559 Affected file lib/silcutil/silcnet.[ch].
561 * If key exchange or rekey protocol is active for a connection
562 parse all packets syncronously since there might be packets
563 in packet queue that we are not able to process without first
564 processing packets before them. Affected file silcd/server,
565 lib/silcclient/client.c.
567 * SilcPacketParserCallback now returns TRUE or FALSE to indicate

600 lib/silcutil/silcutil.[ch].
602 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Resolve the client info when received private message or
605 channel message for a client which nickname we don't know.
606 Affected files lib/silcclient/client_prvmsg.c and
607 lib/silcclient/client_channel.c.
609 * Do not crash in /KEY if client is not connected. Affected
610 file irssi/src/silc/core/silc-channels.c.
612 * Added SilcClientStatus field to the SilcClientEntry in the
613 lib/silcclient/idlist.h.
615 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
616 is incomplete and is being resolved, it won't be resolved
619 Make sure also that USERS command reply does not resolve
620 twice information. Affected file is
621 lib/silcclient/command_reply.c.
623 Make sure that silc_client_get_clients_by_list does not
624 resolve twice same information.
626 * Check for valid client->id in the silc_server_free_client_data.
627 Affected file silcd/server.c.
629 * Fixed /GETKEY nick@server not to crash if the server entry
630 is not found. Affected file lib/silcclient/command.c.
632 * Fixed the silc_server_check_cmode_rights to check the

642 * Call the silc_server_udpate_servers_by_server in the
643 primary router that comes back online in the backup resuming
644 protocol. Otherwise it routes packets wrong. Affected file
645 silcd/server_util.[ch], silcd/server_backup.c.
647 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
649 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
650 lib/silcutil/silcbuffmt.[ch].
652 * Redefined the SILC packet header to include the padding
653 length. Affected file lib/silccore/silcpacket.[ch].
655 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
656 length for maximum padding up to 128 bytes). Affected
657 file lib/silccore/silcpacket.h.
659 * Removed all backwards support for old 0.5.x MAC thingies.
660 The SILC packet header change makes it impossible to be
661 backwards compatible.
663 * Send the ENDING packet with timeout in the backup resuming
664 protocol. This is to assure that all routers has connected
665 to the primary router. Affected file silcd/server_backup.c.
667 * Changed the RNG to take the first IV from random data. It
668 used to take it from zero actually. Changed the RNG also
669 to use /dev/urandom during session. /dev/random is used
670 in initialization. Affected file lib/silccrypt/silcrng.[ch].
672 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
674 * Changed the SILC packet header to have the first two bytes
675 (the packet length) encrypted. Affected files aroung the
676 code tree, lib/silccore/silcpacket.[ch]. Removed the
677 SilcPacketCheckDecrypt callback. It is not needed anymore
678 since the silc_packet_receive_process will determine now
679 whether the packet is normal or special.
681 * Implemented the unidirectional MAC keys. Affected files
682 lib/silcske/silcske.c, silcd/protocol.c and
683 lib/silcclient/protocol.c.
685 * Implemented the packet sequence number to the MAC computation.
686 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
687 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
688 lib/silcclient/protocol.c.
690 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Allow backup router to announce servers. All servers
693 announced by backup router are added to the global list
694 automatically. Update hte server's socket to our primary
695 router also when backup router announces a server.
696 Affected file silcd/packet_receive.c.
698 * Do not update the client->router in the function
699 silc_server_udpate_clients_by_server if the client is on
700 global list. We might fail to find any specific server
701 for locally connected clients and local cell clients. They
702 should still use the `from' and not `to' as client->router.
703 This fixes backup router resuming protocol. Affected file
706 * Decrease channel statistics count only if the channel
707 deletion worked. Affected files are silcd/server.c and
710 * Added silc_server_update_servers_by_server to update origin
711 of all server entries. Used during backup router protocol.
712 Affected files silcd/server_util.[ch], silcd/server.c. and
713 silcd/backup_router.c.
715 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
716 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
717 silc_hmac_get_hash and silc_hmac_get_name. Affected file
718 lib/silccrypt/silchmac.c.
720 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Assure that router cannot reroute the same channel message
723 to the sender. Affected file silcd/packet_receive.c.
725 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
727 * Made better checks that the channel message is not sent
728 to the router it came from. Affected file is
729 silcd/packet_send.c. Fixed memory leak too.
731 * Announce informations for incoming router connection, but
732 only after checking if it is replaced by backup router.
733 Affected file silcd/packet_receive.c.
735 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Fixed the backup resuming protocol to work in multiple
738 router environment. Affected file silcd/server_backup.c.
740 * Route packet only to one router in the function
741 silc_server_packet_send_to_channel. Affected file is
744 * Fixed silc_server_send_notify_dest to set the broadcast
745 flag. Fixed the silc_server_send_notify_topic to actually
746 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
747 Affected file silcd/packet_send.c.
749 * Changed the SFTP Filesystem interface. Changed the
750 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
751 the filesystem operation function. The SilcSFTPFilesystem
752 is now a context that is allocated by all filesystem allocation
753 functions and it already includes the operations structure
754 and filesystem specific context. It is given as argument
755 now to the silc_sftp_server_start. This made the interface
756 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
757 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
759 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
761 * Changed the backup router adding and getting interfaces
762 in the server. The router that will be replaced by the
763 specified backup router is now sent as argument. Affected
764 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
767 * Added silc_net_addr2bin_ne to return the binary form of
768 the IP address in network byte order. Affected files
769 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
771 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
773 * Check for existing server ID in silc_server_new_server
774 and in silc_server_connect_to_router_final and remove the
775 old entry if it exists. Affected file silcd/packet_receive.c,
778 * Send the channel message always to only one router, either
779 in upstream or downstream. Affected file is
782 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
784 * Wrote the definition of the backup resuming protocol to the
785 protocol specification.
787 * Removed one redundant channel key generation from normal
788 server during joining procedure. Removed one redundant
789 channel key sending from server to router during joining
790 procedure. Affected file silcd/command.c.
792 * Made minor bugfixes to the backup router resuming protocol.
793 Affected file silcd/server_backup.c, server.c.
795 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
797 * Added --disable-asm configuration option. Affected files
798 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
801 * Implemented the backup resuming protocol that is used to
802 resume the primary router position in the cell after the
803 primary router comes back online. Affected files
804 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
805 and silcd/server_util.[ch].
807 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
809 * Sleep two (2) seconds after sending QUIT command to server.
810 Affected file lib/silcclient/command.c.
812 * Assure that if outgoing data buffer is pending do not force
813 send any data. Affected file silcd/packet_send.c.
815 * Assure that if outgoing data buffer is pending do not force
816 send any data. Affected file lib/silcclient/client.c.
818 * Implemented the backup router support when the primary router
819 goes down. The servers and routers can now use the backup
820 router as new primary router without loosing connectivity.
822 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
825 in the server to indicate disabled entry. All data read
826 from the connection will be ignored and no data is sent
827 for entry that is disabled. Affected files are
828 silcd/idlist.h, silcd/server.c.
830 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Created SFTP client and server test programs in the
833 lib/silcsftp/tests directory.
835 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Implemented memory filesystem (virtual filesystem) for
838 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
841 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Implemented the SFTP (SSH File Transfer Protocol) to the
844 lib/silcsftp. It includes SFTP client and SFTP server
847 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
849 * Moved lib/silccore/silcprotocol.[ch] to the
850 lib/silcutil library.
852 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
853 take variable argument list pointer as argument. Affected
854 file lib/silcutil/silcbuffmt.[ch].
856 * Added silc_buffer_set function that is used to set data
857 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
858 Affected file lib/silcutil/silcbuffer.h.
860 * Changed various routines in the core library to use the new
861 silc_buffer_set instead of allocating new buffer only for
864 * Added 64-bit value formatting and unformatting support to the
865 silc_buffer_[un]format routines. Affected file is
866 lib/silcutil/silcbuffmt.[ch].
868 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
869 to includes/bitmove.h.
871 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Fixed channel user mode saving in client library. Affected
874 file lib/silcclient/command[_reply].c.
876 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
878 * Defined the file transfer to the SILC Protocol. Added
879 new packet type SILC_PACKET_FTP and defined File Transfer
880 Payload. The mandatory file transfer protocol is SFTP
881 (SSH File Transfer Protocol). Affected file in addition
882 of the internet draft is lib/silccore/silcpacket.h.
884 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
885 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
886 is used as part of backup router protocol when the primary
887 router of the cell is back online and wishes to resume
888 the position as primary router.
890 * Redefined the MAC generation keys in the protocol. The
891 same key is not used anymore in both direction. Both
892 direction will now use different keys for sending and
893 receiving. This fixes a potential security flaw. This
894 change causes incompatibilities in the protocol.
896 * Redefined also the MAC computation from the packet.
897 An packet sequence number is now added to the MAC
898 computation. This prevents possible replay attacks against
899 the protocol. This change too causes incompatibilities
902 Added `sequence' field to the SilcPacketContext to hold
903 the current sequence number for the packet.
905 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Added `created' field to the SilcIDListData in the file
908 silcd/idlist.h to indicate the time when the entry was
911 * Added `created' field to the SilcChannelEntry too. Affected
914 * Added `creation_time' aguments to all the announcement functions
915 in the server. If it is provided then only the entries that
916 was created after the provided time frame are actually
917 announced. Affected file silcd/server.[ch].
919 * The protocol says that the Channel ID's IP address must be
920 based on the router's IP address. Added check for this in
921 the silc_server_new_channel when processing incoming New Channel
922 Payload. Affected file silcd/packet_receive.c.
924 * Print out the correct version with --version in SILC client.
925 Affected file irssi/src/silc/core/silc-core.c.
927 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Fixed WHOWAS command to check for completnes of the client
930 entry always, not just when the command is coming from client.
931 Affected file silcd/command.c.
933 * Added new function silc_server_packet_queue_purge to purge the
934 outgoing data queue to the network. After the function returns
935 it is guaranteed that the outgoing packet queue is empty.
936 Affected file silcd/packet_send.[ch].
938 * Purge the outgoing packet queue in the rekey protocol's final
939 callback to assure that all rekey packets go to the network
940 before quitting the protocol. Affected file silcd/server.c.
942 * Added silc_client_packet_queue_parse as similar function as
943 in server to the client library. The affected file is
944 lib/silcclient/client.c.
946 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
948 * Splitted silcd/server.c and created silcd/server_util.[ch]
949 for utility functions.
951 * Added new socket flag SILC_SF_DISABLED to indicate that the
952 connection is open but nothing can be sent to or received from
953 the connection. Affected file lib/silcutil/silsockconn.[ch].
954 The checking for disabled socket is checked in the low level
955 silc_socket_write and silc_socket_read functions.
957 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
959 * Allow only nicknames and channel names that fits into the
960 7-bit unsigned char ASCII set. Affected file silcd/command.c.
962 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * When processing JOIN command reply in server check that if
965 the channel exists in our global list we'll move it the local
966 list. Affected file silcd/command_reply.c.
968 * Fixed the check whether client is joined on the channel already
969 in JOIN command. Affected file lib/silcclient/command.c.
971 * Fixed the JOIN command reply to check whether the channel
972 already exists. Affected file lib/silcclient/command_reply.c.
974 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Added silc_ske_status_string to map the SKE error numbers
977 to readable strings. The affected files are
978 lib/silcske/silcske[_status].[ch].
980 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Do not show the private channels on the WHOIS channel list
983 as it is not allowed by the protocol. The affected file is
986 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Assure that the packet length digged from the actual packet
989 is something sensible in the silc_packet_decrypt_rest_special
990 in lib/silccrypt/silcpacket.c.
992 * Free and NULL the allocated pointer in silc_hmac_alloc if
993 the HMAC allocation fails. The affected file is
994 lib/silccrypt/silchmac.c.
996 * Print the selected security properties to the log files in
997 the server. Affected file silcd/protocol.c.
999 * Add SKE's reference counter even if calling the completion
1000 callback manually. Otherwise it goes negative, although it
1001 does not cause any problems. The affected file is
1002 lib/silcske/silcske.c.
1004 * Remove the client entry with short timeout after giving the
1005 KILL command. Affected file lib/silcclient/command.c.
1007 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1008 case all found clients are already disconnected (WHOWAS would
1009 found them) in the server. Affected file silcd/command.c.
1011 * Update the last_receive (time of last data received) to be
1012 updated only when received private or channel message so that
1013 the idle time showed in WHOIS makes more sense.
1015 * Added boolean field `valid' in to the SilcClientEntry in the
1016 client library to indicate whether the entry is valid or not.
1017 This fixes the nickname change bug on channel when changing
1018 the nickname to be same than the old (like nick to Nick) the
1019 nickname formatter doesn't set the new nick anymore to Nick@host.
1020 Affected file lib/silcclient/idlist.[ch].
1022 * Now actually fixed the nickname changing on disconnection.
1023 Added new function silc_change_nick to the Irssi SILC Client.
1024 Affected file irssi/src/silc/core/client_ops.c,
1025 irssi/src/silc/core/silc-nicklist.[ch].
1027 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Check that the public key exists in the GETKEY command before
1030 trying to encode it. Affected file silcd/command.c.
1032 * Print some notifications on received public keys with GETKEY
1033 command in the Irssi SILC Client. Affected files are
1034 irssi/src/fe-common/silc/module-formats.[ch],
1035 irssi/src/silc/core/client_ops.c.
1037 * Use IDENTIFY command to resolve the server information in the
1038 GETKEY command instead of INFO command. Affected file
1039 lib/silcclient/command.c.
1041 * All command reply functions in the client library now calls
1042 the pending command reply callbacks even if an error has
1043 occurred. The server has done this a long time and now it was
1044 time to move the client library to this as well. Now all
1045 errors can be delivered back to the pending command reply
1046 callbacks if necessary. Affected files are
1047 lib/silcclient/command[_reply].[ch].
1049 * Change the nickname on disconnection back to the username
1050 because in reconnect the server will enforce it to it anyway.
1051 Affected file irssi/src/silc/core/silc-servers.c.
1053 * Fixed a config file parsing bug in the Irssi SILC client.
1054 Affected file irssi/src/silc/core/clientconfig.c.
1056 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * When printing the channel mode on JOIN, verify that the
1059 channel key and channel's HMAC are valid. Affected file
1060 irssi/src/silc/core/client_ops.c.
1062 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1065 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1066 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1068 * Removed channel key rekey task deleting from the function
1069 silc_server_save_channel_key. Affected file silcd/server.c.
1070 Added explicit timeout task context instead that is used to
1071 delete the task if we are registering a new task before the
1072 new task has elapsed.
1074 * When channel key rekey occurs the client library now saves
1075 the old channel key for a short period of time (10 seconds) and
1076 is able to use it in case some is still sending channel
1077 messages encrypted with the old key after the rekey. Affected
1078 file lib/silcclient/[idlist.h|client_channel.c].
1080 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Added check to the silc_server_new_id_real to not accept
1083 new ID if it is the sender's own ID. Affected file is
1084 silcd/packet_receive.c.
1086 * Assure that we do not announce ourself or the one we've
1087 sending our announcements when we're router and are announcing
1088 servers to our primary router. Affected file silcd/server.c.
1090 * Fixed silc_server_command_identify_check_client to assemble
1091 correct WHOIS packet. It send corrupted WHOIS packet and
1092 caused problem with router to router connections. Affected
1093 file silcd/command.c.
1095 Fixed also silc_server_command_whois_check the same way
1096 as for the IDENTIFY command.
1098 * Added new SilcIDListStatus to the server in the SilcIDListData
1099 structure. The status now includes the current status of
1100 the entry (like registered, resolved etc.). Affected file
1101 silcd/idlist.[ch]. Defined a bunch of different status types
1102 as well. This replaced the old boolean registered field as well.
1104 Added resolve_cmd_ident field to the SilcClientEntry structure
1105 too so that if the entry is for example being resolved so
1106 another command may attach to the same pending command reply
1107 without requiring to resolve the same entry again. This concept
1108 should optimize the WHOIS and the IDENTIFY resolving under
1109 heavy load by taking away unnecessary resolving for entries
1110 that are being resolved already.
1112 Added support for adding multiple pending commands for one
1113 command idenfier. Affected file silcd/command[_reply].[ch].
1115 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1116 before deleting the data. Otherwise the hash table will have
1117 freed data in comparison functions. Affected file is
1118 silcd/command_reply.c.
1120 * Fixed silc_idlist_replace_client_id to add the new entry to
1121 the cache with NULL nickname. Otherwise there will be invalid
1122 memory as the nickname after the nickname is freed. Affected
1123 file silcd/packet_receive.c.
1125 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1126 saved into wrong slots because the previous number of entries
1127 was not taken into account. Affected file silcd/idlist.c.
1128 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1130 * If we are router and we receive JOIN notify to a channel that
1131 does not have any users then notified client is marked as the
1132 channel founder, as it is it. The affected file is
1133 silcd/packet_receive.c
1135 * Added to the extended hash table API's table_del_*ext functions
1136 the destructor as argument too, so that the caller can decide
1137 which destructor to use or whether to use destructor at all.
1138 Affected file lib/silcutil/silchashtable.[ch].
1140 * Fixed ID Cache purging. It actually deleted the entries from
1141 the hash table after the data was freed. The hash table ended
1142 up comparing freed memory. The affected file is
1143 lib/silccore/silcidcache.c.
1145 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Fixed Irssi SILC client's KILL command's HELP syntax.
1149 * The USERS command now resolves the detailed user information
1150 if the userinfo field is missing. Affected file is
1151 lib/silcclient/command_reply.c.
1153 * Do not print error in silc_file_read if the read file does
1154 not exist. Just silently return NULL. Affected file is
1155 lib/silcutil/silcutil.c.
1157 * Fixed the silc_log_output to not wine about NULL filename
1158 and to not create some bogus " " filename. Affected file is
1159 lib/silcutil/silclog.c.
1161 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1163 * Fixed various printing bugs on the user interface in the
1164 Irssi SILC Client. Minor changes that were forgotten from
1167 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Fixed the configure.in.pre and the compilation and distribution
1170 environment to support the new autoconf 2.52. That version is
1171 now required to compile the CVS trunk.
1173 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1176 to generally parse user@fqdn format strings. Affected file
1177 lib/silcutil/silcutil.c.
1179 * Added nickname_format and nickname_force_format fields to the
1180 SilcClientParams structure. The first one defines the format
1181 for the nicknames that the library will enforce if the receives
1182 multiple same nicknames. The second one is boolean value and
1183 can be used to force the library to always enforce the format
1184 to the nicknames regardles whether there are multiple nicknames
1185 or not. This configurable formatting was employed to flexibly
1186 support accessing multiple nicknames from the user interface.
1187 The userinterface can now set the nicknames to what ever format
1188 they prefer. Affected file lib/silcclient/silcapi.h.
1190 Added function silc_client_nickname_format to the file
1191 lib/silcclient/idlist.c. It performs the nickname formatting.
1193 Added new field `hostname´ to the SilcClientEntry context.
1194 It holds the hostname of the client. Affected file is
1195 lib/silcclient/idlist.h.
1197 * Irssi SILC Client sets the nicknames in nick@hostn format.
1198 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1199 irssi/src/silc/core/silc-core.c.
1201 The WHOIS printing now also shows both the real nickname and
1202 the formatted nickname so that user knows how to access the
1203 user if there are multiple same nicknames cached. Affected
1204 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1205 printing formatting too to take the hostname now as a separate
1206 argument. The Affected file is
1207 irssi/src/fe-common/silc/modules-formats.[ch].
1209 * Changed the silc_client_get_clients_local to accept the formatted
1210 nickname as argument. It accepts the real nickname too but the
1211 formatted nickname can be used to find the true entry from
1212 multiple entries. Affected file lib/silcclient/silcapi.h and
1213 lib/silcclient/idlist.c.
1215 * Added nickname_format_parse field to the SilcClientParams.
1216 It is a callback function provided by the application to parse
1217 the nickname out of the formatted nickname string. The library
1218 calls it to get the nickname from the formatted string. Since
1219 the application generally knows better the format of the nickname
1220 string it parses it instead of the library, even though library
1221 encodes the formatted string. If the callback function is not
1222 provided then the library will use the string as is. The
1223 affected file is lib/silcclient/silcapi.h.
1225 * All the nickname strings passed to the client library in
1226 commands are now expected to be formatted nickname strings.
1227 If the command does not support the formatted nickname string
1228 it will assume that the sent string is the actual nickname.
1229 Affected file lib/silcclient/command.c.
1231 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Added public key authentication support to OPER and SILCOPER
1234 commands in the client library. Affected file is
1235 lib/silcclient/command.c.
1237 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Changed the get_auth_methdod client operation to be asynchronous.
1240 It can be async if the application resolves the authentication
1241 method from the server during the negotiation. Added new
1242 SilcGetAuthMeth completion callback that the application will
1243 call after resolving the authentication method.
1245 Added function silc_client_request_authentication_method that
1246 the application can use to resolve the authentication method
1247 from the server. Added also SilcConnectionAuthRequest callback
1248 that the library will call after the server has replied. The
1249 application can call this function if it does not know the
1250 current authentication method.
1252 Affected files are lib/silcclient/client.c and
1253 lib/silcclient/silcapi.h.
1255 * The Irssi SILC client now automatically resolves the authentication
1256 method incase any configuration information is not present (and
1257 currently there never is). The affected file is
1258 irssi/src/silc/core/client_ops.c.
1260 * Fixed public key authentication from the client library.
1261 Affected file lib/silcclient/protocol.c. Changed also the
1262 protocol specification about the public key authentication in
1263 the connection authentication protocol. The actual data to be
1264 signed is now computed with a hash function before signing.
1266 * Fixed the public key authentication from the server as well.
1267 Affected file silcd/protocol.c.
1269 * Removed the mlock()'s from the memory allocation routines.
1270 Affected file lib/silcutil/silcmemory.c. The ./configure does
1271 not check anymore for the mlock(). Affected file is
1274 * Fixed USERS command in server to allow the execution of the
1275 command for private and secret channels if the client sending
1276 the command is on the channel. Affected file silcd/command.c.
1278 * Fixed silc_client_get_clients_local to return the clients
1279 count correctly. It could return wrong value. Affected file
1280 lib/silcclient/idlist.c.
1282 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1285 types. The assembler optimizations seemed not to like 64-bit
1286 data types. The assmebler optimizations thus are now enabled
1287 also for BSD systems as opposed to only enable them for Linux.
1289 * Do not check for threads at all on BSD systems. Affected
1290 file configure.in.pre.
1292 * Removed -n and -h options from the Irssi SILC Client since
1293 they are not used in silc.
1295 * Fixed the prime generation to assure that the first digit
1296 of the generated random number is not zero since our conversion
1297 routines does not like number strings that starts with zero
1298 digit. If zero digit is seen the random number is regenerated.
1299 This caused some corrupted RSA keys when the zero first digit
1300 was met. Affected file lib/silcmath/silcprimegen.c.
1302 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Fixed WIN32 configuration in the ./configure script.
1305 Fixed to include xti.h on environments that has it.
1306 Patches by Carsten Ilchmann and andrew.
1308 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Changed the silc_id_create_client_id to be collision
1311 resistant. It is now assured that there cannot be created
1312 two same client ID's. I suspect that some weird bugs in
1313 the server were actually caused by duplicate Client IDs.
1314 Affected file silcd/serverid.[ch]. A router receiving
1315 new ID now also assures and informs the sending server
1316 if the ID caused collision.
1318 * Changed the silc_id_create_channel_id to also assure that
1319 there are no collisions.
1321 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Statement about ignoring the Mutual Authentication flag when
1324 performing rekey with PFS was a bit misleading. It is ignored
1325 if it was set in the initial negotiation, it cannot be even
1326 set in the rekey. Fixed in the ke-auth draft. Started the
1327 new versions of the protocol drafts in the doc/.
1329 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1331 * Fixed a bug in silc_client_command_identify_save when saving
1332 new channel information. The channel name was no duplicated
1333 and caused crash on exit. Affected file is
1334 lib/silcclient/command_reply.c.
1336 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Fixed the getkey command handling in the server. Send just
1339 empty OK reply to the sender if the key could not be fetched
1340 (but everything else was ok, like the key just was not available).
1341 Changed the public key parameter to optional in the protocol
1342 specs so that empty OK reply can be sent. Affected file
1345 Added a message to Irssi SILC client to tell to user if the
1346 server did not return a public key.
1348 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Fixed a channel key regeneration bug. It registered new
1351 timeout tasks exponentially until all system resources were
1352 used. Affected file silcd/server.c.
1354 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Added the SILC Document generator to the scripts/silcdoc.
1357 It can be used to generate the Toolkit Reference Manual out
1358 of the source tree. Internally it will also use the RoboDoc
1359 generator now imported in util/robodoc.
1361 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Added couple of return's in rekey protocol if error orccurred
1364 during the protocol. The execution must be terminated.
1365 Affected file silcd/protocol.c. Also, terminate the protocol
1366 always with timeout.
1368 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * The client's Client ID was created initally from the wrong
1371 nickname (it could have been in format nick@host) in the
1372 silc_server_new_client. Affected file silcd/packet_receive.c
1374 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Added some SILC_LOG_ERROR's to various error conditions
1377 if client could not be added to ID cache. Affected files
1378 silcd/packet_receive.c and silcd/server.c.
1380 * When client's sock->user_data is freed, NULL also the
1381 client->router and client->connection pointers. Added check
1382 for these pointers being NULL to various places around the
1383 code. Affected file silcd/server.c.
1385 * Added client->data.registered == TRUE checks to various
1386 places around the code to assure that unregistered client's
1387 are not handled when it is not allowed. Affected file
1390 * Added `bool registered' fields to all
1391 silc_idlist_[server|client]_get_* routines to indicate whether
1392 the fetched client needs to be registered or not. Affected
1393 file silcd/idlist.[ch].
1395 * Add your own entry as registered to the ID cache in the
1396 server. Affected file server.c.
1398 * Fixed a bug in silc_server_new_server. The SilcServer was
1399 set as the new server's context instead of SilcServerEntry.
1400 This naturally caused some weird bugs.
1402 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Do not delete the channel rekey task when adding it
1405 for in silc_server_create_channel_key.
1407 * Changed the silc_server_create_channel_key to return
1408 TRUE or FALSE to indicate the success of the channel key
1411 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Fixed MSVC++ project files and added missing files to
1414 Makefiles under win32/.
1416 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Do not add TCP_NODELAY flag if the operating system
1419 does not have it defined. Affected files are
1420 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1422 * Fixed buffer overflow from Irssi SILC Client. Affected
1423 file irssi/src/fe-common/core/themes.c.
1425 * Fixed double free in client library in the file
1426 lib/silcclient/client.c when disconnecting from server.
1428 * Applied double free patch from cras to Irssi SILC client.
1429 Affected files irssi/src/core/[modules/expandos].c
1431 * Fixed the disconnection handling to Irssi SILC Client.
1432 The application must call silc_client_close_connection
1433 in ops->connect client operation in case of failure of
1434 the connection. Affected file is
1435 irssi/src/silc/core/client_ops.c.
1437 * Do not set sock->protocol to NULL in the function
1438 silc_client_close_connection after executing the protocol's
1439 final callback since the sock might not be valid anymore.
1440 Affected file lib/silcclient/client.c.
1442 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Do not enable SILC_THREADS if the linking with libpthread
1445 did not happen. Affected file configure.in.pre.
1447 * Added notion to protocol specification that server must
1448 verify the sent authentication payload with CMODE when
1449 setting the channel founder key. Implemented it to the
1450 server. Affected file silcd/command.c.
1452 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Added _EXTRA_DIST SILC distribution variable to the
1455 distributions file. It is used to conditionally add extra
1456 files or directories to the specific distribution. Affected
1457 files ./prepare, Makefile.am.pre and distributions.
1459 Removed the `_' from the start of the distribution names.
1462 * Added README.WIN32 for instructions to compile the Toolkit
1465 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Fixed a double free in disconnection in the server. Affected
1468 file is silcd/server.c.
1470 * Fixed the lib/silcske/groups.c to work now also with GMP
1471 MP library. The string conversion did not work when using
1472 specific base and the base is indicated in the string as well.
1474 * Created win32/ directory which now includes MSVC++ specific
1475 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1476 It will appear only in the toolkit distribution
1478 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1480 * Changed the key material distribution function in case when
1481 the hash output is too short. The data is now concatenated
1482 a bit differently than it used to. Made the change to the
1483 SKE protocol specification.
1485 * Added better GMP detection to configure.in.pre. A patch
1488 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1490 * Fixed a minor bug in SKE that might cause some problem on
1491 some platforms. Affected file lib/silcske/silcske.c.
1493 * Added the cookie checking for initiator in the SKE. It checks
1494 that the responder returns the sent cookie unmodified. The
1495 affected file is lib/silcske/silcske.c. Added new SKE
1496 error type INVALID_COOKIE that can be sent during the
1497 negotiation. Fixed some memory leaks as well.
1499 * Added the "invalid cookie" error message to Irssi SILC client's
1502 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Added `task_max' field to the SilcClientParams to indicate
1505 the maximum tasks the scheduler can handle. If set to zero,
1506 default values are used. Affected file lib/silcclient/silcapi.h.
1508 * Fixed memory leaks in silc_client_close_connection. Affected
1509 file lib/silcclient/client.c.
1511 * Added silc_client_del_client_entry to client library to free
1512 all memory of given client entry. Affected file is
1513 lib/silcclient/idlist.[ch].
1515 * Added new functions silc_client_del_channel and
1516 silc_client_del_server to delete channel and server entries.
1517 Affected file lib/silcclient/[silcapi.h/idlist.c].
1519 * Removed silc_client_del_client_by_id from silcapi.h.
1521 * Fixed the INFO command to return the server's own info
1522 correctly when querying by Server ID. Affected file is
1525 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1527 * Removed the non-blocking settings in WIN32 code in the
1528 silc_sock_[read/write] and added SleepEx instead. Affected
1529 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1530 of input data is now checked with FIONREAD and ioctlsocket.
1532 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1534 * Call silc_schedule_task_del_by_context in the
1535 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1536 Affected file lib/silccore/silcprotocol.c.
1538 * Call silc_protocol_cancel for active protocols in the
1539 silc_server_close_connection if the funtion
1540 silc_server_free_sock_user_data has not been called.
1541 Affected file silcd/server.c.
1543 * Generic tasks cannot be deleted using the del_by_fd
1544 task deleting function since generic tasks does not match
1545 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1547 * Added a notion to SILCOPER help file that the SILCOPER works
1548 only on router server, not on normal server.
1550 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Added for WIN32 support for the new scheduler as well.
1553 Affected file lib/silcutil/win32/silcwin32schedule.c.
1555 * Fixed the SHA1 implementation to work on various platforms.
1557 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1560 API. It is part of the scheduler now. Everything else is
1561 as previously but some functions has changed their names.
1562 Checkout the lib/silcutil/silcschedule.h for the interface.
1563 Updated all applications to use the new interface. Affected
1564 files are lib/silcutil/silcschedule.[ch].
1566 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Found a bug in the SKE implementation. The HASH value,
1569 specified by the protocol, was not computed correctly. The
1570 public key of the responder was not added to the computation
1571 even though it is mandatory. Affected file lib/silcske/silcske.c.
1572 This unfortunately causes incompatibilities with older
1573 clients and servers.
1575 * Added WIN32 specific network init and uninit functions:
1576 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1577 the Winsock2. Affected file lib/silcutil/silcnet.h and
1578 lib/silcutil/win32/silcwin32net.c.
1580 * Set the socket always to nonblocking mode on WIN32 after
1581 reading data or writing data. Affected file is
1582 lib/silcutil/win32/silcwin32sockconn.c.
1584 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Fixed various compilation problems under WIN32. Affected
1587 files lib/silcutil/win32/silcwin32thread.c and
1588 lib/silcutil/win32/silcwin32schedule.c.
1590 * Removed all _internal.h #includes from public header
1591 files. Internal headers must never be included from
1594 Removed also the lib/silcske/payload_internal.h file.
1596 * All include files that may be needed (public and some others
1597 included by the public headers) by application developers are
1598 now copied to the ./includes directory. It does not copy any
1599 internal headers. Affected file Makefile.defines.pre and all
1600 Makefile.am's under lib/ and subdirs.
1602 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Do not change the ~/.silc directory's permissions automatically.
1605 Affected file irssi/src/silc/core/clientutil.c.
1607 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Do not cancel the protocol in silc_server_close_connection
1610 it might cause recursion. Now cancelled in the function
1611 silc_server_free_sock_user_data. Affected file silcd/server.c.
1613 * Fixed the silc_server_remove_clients_by_server to regenerate
1614 the channel keys correctly finally. Added also new function
1615 silc_server_remove_clients_channels to actually do it.
1616 Affected file silcd/server.c.
1618 * Fixed the silc_server_new_channel to not crash by giving
1619 wrong router to the new channel. Affected file is
1620 silcd/packet_receive.c.
1622 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1625 which is given as argument to the silc_client_alloc now.
1626 It can be used to configure the client and set various parameters
1627 that affect the function of the client.
1629 * The USERS command in server did not check whether the channel
1630 is private or secret. Affected file silcd/command.c.
1632 * Added new argument to the USERS command in protocol specification.
1633 The USERS command now can take the channel name as argument
1634 as well. Added support for this in client and server and
1635 updated the protocol specs.
1637 * Completed the GETKEY command in client. It can be now used
1638 to fetch also servers public key not only some clients.
1639 Affected files lib/silcclient/command[_reply].c.
1641 * Added silc_client_get_server to return server entry by the
1642 server name. Affected files lib/silcclient/silcapi.h and
1645 * Redefined the IDENTIFY command in protocol specification to be
1646 more generic. It now can be used to query information about
1647 any entity in the SILC Network, including clients, servers and
1648 channels. The query may be based either the entity's name
1649 or the ID. Added support for this in both client and server.
1651 Affected files silcd/command.c and lib/silcclient/command.c
1652 and command_reply.c.
1654 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1655 the _from_client and _from_server functions. Affected file
1658 * Added silc_client_get_channel_by_id_resolve to the file
1659 lib/silcclient/silcapi.h to resolve channel information by
1660 its ID. Added also silc_client_get_channel_by_id that
1661 does not resolve it from the server.
1663 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Added SilcServerEntry context into the client library
1666 to represent one server. The INFO command now allocates
1667 these to save the resolved server info. For now on the
1668 client library will also keep information about servers,
1669 connected and resolved with INFO.
1671 The INFO command now allocates the SilcServerEntry context
1672 and saves the server info there. The COMMAND_REPLY in
1673 the INFO now returns the parameters to application in
1674 same order as defined in the protocol specification.
1676 The entries are cached in the client->server_cache.
1678 * The INFO command is now issued after received the Client ID
1679 from the server. Affected file lib/silcclient/client.c.
1681 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1682 to the application as the mode changer might be server.
1683 It is guaranteed that NULL is not returned anymore to the
1684 application. Affected file lib/silcclient/client_notify.c.
1686 The ID Type is now also passed to the application so that
1687 it can check whether the returned entry is SilcClientEntry
1690 Added new function silc_client_get_server_by_id to return
1691 the server entry by ID. Affected files are the
1692 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1694 * Do not create the channel in the Irssi SILC Client when issuing
1695 the JOIN command but when received the sucessful JOIN command
1696 reply. Otherwise the channel might get created even though we
1697 could not join it. The Affected file is
1698 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1700 * Fixed a channel joining bug in router. The router must also
1701 check the channel modes, invite and ban lists etc. when serving
1702 the JOIN command sent by normal server. Affected file is
1703 silcd/command.c. The router now resolves the client's
1704 information from the server who sent the JOIN command if it
1705 does not know it, and processes the JOIN command only after
1708 * Changed the SilcCommandCb to take new argument; void *context2.
1709 Affected file lib/silccore/silccommand.h
1711 The second argument in the command callbacks in the server now
1712 includes the SilcServerCommandReplyContext if the command was
1713 called as pending command callback from the command reply.
1714 Otherwise it is NULL. When called as pending the status of the
1715 command reply will be checked and if it was erronous the
1716 error will be sent to the original sender of the command.
1717 This way the client always receives the error messages even
1718 though the server was actually the one who received the error
1719 when it resent the command to router, for example. Affected
1720 files silcd/command[_reply].[ch].
1722 * Fixed sending WHOWAS command's error message to client if
1723 the requested client could not be found. It was missing.
1726 * Changed the CMODE and CUMODE commands reply arguments in the
1727 protocol specification. The Channel ID is now sent in both
1728 of the commands to identify the channel. Implemented this
1729 new feature to the client and server. Affected files
1730 lib/silcclient/command_reply.c and silcd/command.c.
1732 * Made better checks for invite and ban lists in the JOIN
1733 command in server. Affected file silcd/command.c.
1735 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * The server now performs the incoming host IP/DNS lookup
1738 using the silc_socket_host_lookup and thus does not block
1739 the server anymore. Affected file silcd/server.c.
1741 * Completed the multi-thread support for SILC Scheduler in
1742 the lib/silcutil/silcschedule.c.
1744 * Fixed the configure.in.pre to detect the pthread correctly
1747 * Fixed a deadlock in silc_task_queue_wakeup in the file
1748 lib/silcutil/silctask.c.
1750 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Added new function silc_schedule_wakeup that is used in
1753 multi-threaded environment to wakeup the main thread's
1754 schduler. It needs to be used when a thread adds a new task
1755 or removes a task from task queues. After waking up, the
1756 scheduler will detect the task queue changes. If threads
1757 support is not compiled in this function has no effect.
1758 Implemented the wakeup mechanism to both Unix and WIN32
1759 systems. Affected files are lib/silcutil/silcschedule.[ch],
1760 lib/silcutil/unix/silcunixschedule.c and the
1761 lib/silcutil/win32/silcwin32schedule.c.
1763 * Added new function silc_task_queue_wakeup to wakeup the
1764 scheduler by the specified task queue. Affected file
1765 lib/silcutil/silctask.[ch].
1767 * The silc_socket_host_lookup_start now wakes up the scheduler
1768 after adding the timeout task. Affected file is
1769 lib/silcutil/silcsockconn.c.
1771 * The silc_socket_host_lookup is synchronous now if the threads
1772 support is not compiled in. However, the callback is still
1773 called asyncronously through the scheduler, anyway. Affected
1774 file lib/silcutil/silcsockconn.c.
1776 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Added new function silc_socket_host_lookup to perform
1779 asynchronous IP and FQDN lookups for the socket connection.
1780 Affected files lib/silcutil/silcsockconn.[ch].
1782 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1785 that may or may not compile the mutex support in.
1787 Changed the silc_mutex_alloc interface. It allocates the
1788 mutex now to the sent pointer and returns TRUE or FALSE.
1790 Affected file lib/silcutil/silcmutex.h.
1792 * Wrote the SILC Task Queue interface to support multi-threads.
1793 Affected file lib/silcutil/silctask.[ch].
1795 * Wrote the SILC Scheduler to support multi-threads. Affected
1796 file lib/silcutil/silcschedule.c.
1798 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1801 in lib/silcutil/win32/.
1803 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Defined SILC Mutex API and SILC Thread API and implemented
1806 them for Unix. Affected files are
1807 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1808 lib/silcutil/unix/silcunixmutex.c and
1809 lib/silcutil/unix/silcunixthread.c.
1811 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Fixed the silc_server_remove_clients_by_server's channel
1814 key re-generation. The hash table handling was incorrect
1815 and would not work with many channels. Affected file is
1818 * Fixed some memory leaks around the server code.
1820 * Rewrote the silc_server_get_users_on_channel to support IPv6
1821 based Client ID's. Affected file silcd/server.c.
1823 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1824 specification. However, a separate document must be written
1825 to define the detailed signing procedure and the payload
1826 associated with the flag. Defined the flag to the
1827 lib/silccore/silcchannel.h as well.
1829 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Changed the dynamic tables to static size tables in the
1832 lib/silccrypt/silchmac.c.
1834 * Removed GCC dependencies from the code. A patch by cras.
1836 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Do not show the error "Error receiving packet bla bla"
1839 in server if it really was not an error (-2 means that reading
1840 is pending). Affected file silcd/server.c.
1842 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Fixed a possible crash in silc_server_remove_clients_by_server
1845 in silcd/server.c. Fixed there also some memory leaks.
1847 * Fixed the silc_idlist_replace_client_id. It could replace
1848 wrong key in the hash table. Affected file silcd/idlist.c.
1850 * Do not check whether there are global users on the channel
1851 if the channel->global_users is FALSE. Affected functions
1852 silc_server_remove_from_one_channel and
1853 silc_server_remove_from_channels in silcd/server.c. Also,
1854 do not check if the removed client is local as we can be
1855 sure that global client was not removed from the channel
1856 and checking for global users is not needed.
1858 * The silc_server_remove_clients_by_server now re-generates
1859 the channel keys correctly for those channels that had
1860 clients removed from them. Affected file silcd/server.c.
1862 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Found the reason of random crashes in the server. We weren't
1865 ignoring the SIGPIPE signal (which can be sent in write())
1866 and it crashed the server. Affected file silcd/silcd.c.
1868 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Assure that sock->user_data is not NULL in the function
1871 silc_server_packet_send in silcd/packet_send.c.
1873 * Disconnect the remote connection if it could not be added
1874 to any ID lists in the server. The affected file is
1877 * Check in silc_server_packet_send[_real/dest] that the
1878 socket is not disconnecting and ignore the data if it is.
1879 Affected file silcd/packet_send.c.
1881 * Define inline to __inline on native WIN32 compilation.
1882 Affected file includes/silcwin32.h.
1884 * Added some explicit type casts for inline code since MSVC
1885 require them. Affected files lib/silcutil/silcbuffer.h,
1886 lib/trq/silcdlist.h and lib/trq/silclist.h.
1888 * Print warning in log files from now on if the packet
1889 decryption fails. Affected file silcd/server.c.
1891 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Changed the `say' client operation's interface to accept
1894 new `type' argument to indicate the type of the message sent
1895 by the library. The application may filter the library's
1896 messages according the type. The affected file is the
1897 lib/silcclient/silcapi.h.
1899 * Added two new functions to lib/silcclient/silcapi.h:
1900 silc_client_del_client and silc_client_del_client_by_id.
1901 Affected file lib/silcclient/idlist.c.
1903 * Moved the clientincludes.h from includes/ to silc/ and
1904 serverincludes.h from includes/ to silcd/.
1906 * The modes for the CMODE and CUMODE are now passed as
1907 uint32 for application with COMMAND_REPLY. The affected
1908 file is lib/silcclient/command_reply.c.
1910 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * /WHOIS without arguments shows client's own information.
1913 Affected file lib/silcclient/command.c.
1915 * Changed PING to not accept any arguments. The specs
1916 says that client can ping only the connected server so
1917 requiring an argument is not needed. Affected file is
1918 lib/silcclient/command.c.
1920 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Fixed a fatal bug in private message sending and reception
1923 encryption and decryption when using private message keys.
1924 The implementation was incorrect and did not follow the
1925 specification. It causd that some of the message were
1926 lost since it did not use the sending and receiving keys
1927 as the protocol suggests. This has been fixed and will cause
1928 incompatibilities with older clients when sending private
1929 message encrypted with private message keys. Affected files
1930 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1931 and various other in Irssi SILC Client.
1933 Added `responder' boolean argument to the functions
1934 silc_client_add_private_message_key[_ske] to indicate when
1935 the key is added as responder or initiator of the key
1938 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Removed the silc_ske_check_version function and created
1941 a SilcSKECheckVersion callback. Added also a function
1942 silc_ske_set_callbacks that is now used to set all SKE
1943 callbacks. The callback functions are not given to
1944 the SKE functions anymore, but this function is used to
1947 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1949 * Added `silc_version' argument to the silc_client_alloc
1950 to define the version of the application for the library.
1951 The library will use the version string to compare it
1952 against the remote host's (usually a server) version
1953 string. Affected file lib/silcclient/silcapi.h
1955 * Added the KE protocol context to Key Agreement context
1956 in client library so that we can abort the SKE if it
1957 is in process when we get timeout. Affected file is
1958 lib/silcclient/client_keyagr.c.
1960 * Do not resolve the client ID forever if it returns in the
1961 first time that such client does not exist. This was done
1962 for example with private message. Affected file is
1963 lib/silcclient/client_prvmsg.c.
1965 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Do not add regex.h for WIN32. The affected file
1968 includes/silcincludes.h.
1970 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1971 not work yet 100%. It generates the DLL's automatically
1972 when compiling with --with-win32 under cygwin.
1974 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * lib/contrib/regex.c is not compiled on WIN32.
1978 * Added silc_net_get_socket_opt function to the
1979 lib/silcutil/silcnet.h.
1981 * Added includes/silcwin32.h for WIN32 specific includes
1984 * Do not use ptime structure or any of the posix process
1985 functions on WIN32 in lib/silccrypt/silrng.c.
1987 * Added silc_gettimeofday to provide generic function
1988 for struct timeval on all platforms. Added the function
1989 to lib/silcutil/silcutil.h.
1991 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1994 library as they clearly belong there. As a plus side we
1995 can make the actual socket connection routines platform
1998 Added also new generic function silc_socket_read and
1999 silc_socket_write (that used to be silc_packet_[read/write].
2000 The implementation of these are platform specific.
2002 * Added WIN32 specific routines of silc_socket_[read/write]
2003 to lib/silcutil/win32/silcwin32sockconn.c.
2005 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Added preliminary support for native WIN32 compilation under
2008 cygwin (using the -mno-cygwin option for GCC) to the
2009 ./configure.in.pre. The --with-win32 now prepares the
2010 compilation for native WIN32.
2012 * Rewrote the SILC Scheduler interface in the file
2013 lib/silcutil/silcschedule.h. The scheduler is now context
2014 based and does not have anymore any global static scheduler.
2015 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2016 and created lib/silcutil/win32 directory for WIN32 based
2019 * Added Unix specific network routines to the
2020 lib/silcutil/unix/silcunixnet.c and the old
2021 lib/silcutil/silcnet.c includes now only generic routines.
2023 Added WIN32 specific network routines to the
2024 lib/silcutil/win32/silcwin32net.c.
2026 * Added Unix specific utility functions from the
2027 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2029 * Added WIN32 SILC Scheduler to the file
2030 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2033 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Do not handle JOIN notify in the server if the target client
2036 is not registered (idata->registered == FALSE). The affected
2037 file is silcd/packet_receive.c.
2039 * Update the nickrec->founder in event_cumode in the Irssi SILC
2040 client. Affected file irssi/src/silc/core/silc-channels.c.
2042 * Fixed the CUMODE_CHANGE notify handling in the server when
2043 server and router are announcing their clients on channels.
2044 Now the mode changes are saved and notified correctly. The
2045 affected file is /silcd/packet_receive.c.
2047 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2048 They really did not replace the cache entry in the ID Cache.
2049 Now they do that. Affected file silcd/idlist.c.
2051 * Fixed the KICK notify handling in the Irssi SILC client to
2052 update the channel records so that the kicked client does not
2053 appear to be on the channel. The affected file is
2054 irssi/src/silc/core/silc-channels.c.
2056 * Always update the conn->current_channel when executing command
2057 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2059 * Fixed the KILL notify handling in Irssi SILC client to remove
2060 the killed client on all channels.
2062 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Fixed the silc_parse_command_line to remove extra spaces
2065 from the start and end of the arguments. Affected file is
2066 lib/silcutil/silcutil.c.
2068 * Cancel and free any active protocol in the function
2069 silc_server_close_connection. Affected file silcd/server.c.
2071 * Cancel and free any active protocol in the function
2072 silc_client_close_connction. Affected file is
2073 lib/silcclient/client.c.
2075 * Do not execute the KILL command for clients that are in
2076 history (ie. they are not in the network). Affected file is
2079 * Fixed KILL notify handling, client does not crash anymore.
2080 Affected file irssi/src/silc/core/silc-channels.c.
2082 * Reduced the default packet buffer size from 2048 to 1024 in
2083 lib/silccore/silcpacket.c.
2085 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2086 counter to the SKE context that is incresed when the SKE library
2087 performs async operation outside the library. If the outside
2088 process frees the SKE context and FREED status will be set
2089 and the library will detect after the sync operation that the
2090 libary is freed. The affected files are
2091 lib/silcske/silcske[_status].[ch].
2093 * Resolve the client entry information in the function
2094 silc_client_channel_message to assure that NULL pointer is not
2095 passed as client entry to the application. */
2097 * Fixed the task timeout calculation to assure that there is
2098 never negative timeouts. The affected file is
2099 lib/silcutil/silcschedule.c.
2101 * Fixed the channel user mode notification sending in server.
2102 It was sent point-to-point to the router (or to server by router)
2103 but it needs to be destined to a channel. The routines now
2104 supports sending the channel user mode notifys to the channels
2105 when announcing clients and channels. Affected files are
2106 silcd/server.c and silcd/packet_receive.c.
2108 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2109 It did not actually replace the old channel entry in the cache.
2110 Affected file lib/silcclient/client_notify.c.
2112 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2114 * Fixed a possible crash in silc_packet_send_prepare. It now
2115 assures always that there is enough space in the buffer and
2116 at the tail area of the buffer (for MAC).
2118 Fixed the inbound buffer reallocation in silc_packet_read.
2119 It was old code and did not handle the reallocation correctly.
2122 The affected file is lib/silccore/silcpacket.c.
2124 * Fixed buffer overflow in silc_parse_nickname in the file
2125 lib/silcutil/silcutil.c.
2127 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2129 * make install generates new server keys only if there is not
2132 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2135 Added check that if the NOREPLY is set then we will not send
2136 the away message. This avoids infinite loop of away messages
2137 if both clients are away. The affected file is
2138 lib/silcclient/client_prvmsg.c.
2140 * Fixed client crash if /NICK was given without arguments.
2141 Affected file lib/silcclient/command.c.
2143 * Server does not send the invite list in INVITE command back
2144 to the client if the list was not altered. Added this notion
2145 to the protocol spec as well. Affected file silcd/command.c.
2147 Fixed possible crash in INVITE command by checking the
2148 value of silc_server_get_client_route command.
2150 * Fixed the INVITE notify type handling. The arguments are now
2151 taken in correct order and client does not crash. The affected
2152 file is irssi/src/silc/core/silc-channels.c.
2154 Removed the "Inviting xxx to channel" message from the
2155 client library away and let the application handle it.
2156 Affected file lib/silcclient/command.c. Added that message
2157 to Irssi SILC client's message formats.
2159 * Fixed CMODE command crash in client. It now checks the
2160 amount of arguments correctly and does not crash. The affected
2161 file is lib/silcclient/command.c.
2163 * Do not create new channel automatically in silc_channels_join
2164 but check whether the channel by that name already exists.
2165 Affected file irssi/silc/core/silc-channels.c.
2167 * Do not send the SERVER_SIGNOFF to router if the disconnected
2168 entity was the router. Affected file silcd/server.c.
2170 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2171 SILC client as it was missing from there.
2173 Added the handling of the KICK notify to the Irssi SILC client
2174 as it was missing. Added "you have been kicked" message to
2175 Irssi SILC client's message modules formats.
2177 Added the handing of the KILL notify to the Irssi SILC client
2178 as it was missing. Added the kill message module formats
2181 The affected file is irssi/src/silc/core/silc-channels.c.
2183 * The router did not save the channel mode the server announced.
2184 Affected file silcd/packet_receive.c.
2186 * Fixed a possible crash in INFO command in server. If the
2187 server did not provide the server info it crashed. Affected
2188 file silcd/command.c.
2190 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Fixed the GETKEY command in the server to check also the
2193 global list. Otherwise the GETKEY would not work correctly
2194 in normal SILC server. Affected file silcd/command.c.
2196 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Fixed GETKEY crash, it crashed if the command did not succseed.
2200 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2203 is now real and not just an macro interface to GMP.
2205 Removed the entire GMP from the source tree and imported new
2206 NSS MPI library instead. Reason for removing GMP is that it is
2207 extremely large and compiles extremely slow. The NSS MPI
2208 is only a few files and compiles in less than 10 seconds.
2209 The speed is also about the same as GMP. The MPI is imported
2210 to lib/silcmath/mpi.
2212 If the system has GMP installed we will still use the GMP.
2213 If it is not then the NSS MPI will be compiled.
2215 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Merged a long nickname (127 characters long) crash bugfix from
2218 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2220 * Merged a freed memory reference bugfix from Irssi CVS tree.
2221 Affected file irssi/src/core/commands.c.
2223 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * Added the server's public key sving and verification to the
2226 server when performing the SKE. This was missing and the
2227 remote server's (or router's) public key was accepted without
2228 checking whether we have it previously or trust it at all.
2229 Affected file silcd/protocol.c.
2231 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Check in the silc_server_timeout_remote if protocol is active
2234 and make sure that the protocol's final callback is called so
2235 that all memory if freed. Affected file silcd/server.c.
2237 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * silc_server_whois_send_reply crashed the server if the nickname
2240 was 127 characters long. Affected file silcd/command.c.
2242 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Added sanity check to the silc_server_new_client. If the hostname
2245 is provided inside username then check that the provided hostname
2246 really is the same as the resolved one. If the hostname was not
2247 resolved then check it from the public key. Affected file is
2248 silcd/packet_receive.c.
2250 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2251 if the server disconnected us and the connection is not valid
2252 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2254 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2255 the library to the lib/silcutil/silcutil.[ch].
2257 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Close log file after open. Affected file
2260 lib/silcutil/silclog.c.
2262 * Check whether sock == NULL in silc_client_send_packet and return
2263 if it is. Affected file lib/silcclient/silcclient.c.
2265 * Check rec->entry == NULL in the Irssi SILC Client before
2266 sending the channel message. Affecte file is
2267 irssi/src/silc/core/silc-servers.c.
2269 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Merged a splitted window bugfix from Irssi CVS tree. The
2272 affected file is irssi/src/fe-text/textbuffer-view.c.
2274 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2275 It did not print nickname.
2277 * Improved the distributions system a bit.
2279 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2282 irssi/src/fe-text/gui-window.c.
2284 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2285 to in-active server. The affected file is
2286 irssi/src/silc/core/client_ops.c.
2288 * Resolve the client in USERS command reply if the entry does
2289 not have username resolved. The affected file is
2290 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2291 command to WHOIS command to really resolve stuff. The USERS
2292 is not used any more in any critical section so WHOIS can
2293 be used even though it might be slower than IDENTIFY.
2295 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2298 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Changed the protocol API a bit more consistent in the
2301 lib/silccore/silcprotocol.[ch].
2303 * Changed the following headers to ROBODoc format:
2305 lib/silccore/silcpayload.h
2306 lib/silccore/silcprotocol.h
2307 lib/silccore/silcsockconn.h
2309 All core library headers are now formatted.
2311 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Fixed a bug in Irssi SILC client; do not show that you are
2314 server/router operator if you really are not. Affected file is
2315 irssi/src/silc/core/client_ops.c.
2317 * Renamed silc_command_free_payload to silc_command_payload_free.
2318 Affected file lib/silccore/silccommand.h
2320 * Added silcmath.h to include the prototoypes of various routines
2321 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2324 * Changed the following headers to ROBODoc format:
2326 lib/silccore/silcchannel.h
2327 lib/silccore/silccommand.h
2328 lib/silccore/silcid.h
2329 lib/silccore/silcidcache.h
2330 lib/silccore/silcmode.h
2331 lib/silccore/silcnotify.h
2332 lib/silccore/silcpacket.h
2333 lib/silcmath/silcmath.h
2335 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Added checking to the server code not to start the server if
2338 ciphers and stuff are not configured properly. Affected files
2339 silcd/serverconfig.[h] and silcd/server.c.
2341 * Changed the layout of the header files of the public interfaces
2342 in the SILC libraries. The new layout supports ROBODoc
2343 documentation tool (and some others) so that it is easy to create
2344 a library reference manual. All the other headers and source
2345 code must still follow the CodingStyle document. Also source
2346 code must not include these ROBODoc stuffs, only the headers.
2347 Furthermore, all public interface headers must now be named
2348 by using `silc' prefix, example: silcapi.h, silccipher.h.
2349 Some files were renamed due to this. All the other headers
2350 must not be used as public interfaces. I will update the
2351 CodingStyle document later. Changed following headers, so far:
2353 lib/silcclient/silcapi.h
2354 lib/silccore/silcauth.h
2355 lib/silccore/silcprivate.h
2356 lib/silccrypt/silcdh.h
2358 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Removed silc_client_packet_send_flush from the client library
2363 as it is not needed. Affected file lib/silcclient/client.[ch].
2365 * Added printing of message of unresolved authentication method
2366 to the Irssi SILC client. Added it to the module formats.
2367 Removed the same message from the client library.
2369 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Added new distribution feature, DISTLABEL. Every distribution
2372 can define own preprocessor label that can be used in the
2373 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2374 file distributions, acconfig.h.pre and prepare.
2376 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Added Makefile.defines_int to include the actual definitions
2379 for Makefile.defines.in. Tested the new distribution system,
2380 created distributions and tested installation.
2382 * Added AWAY message printing to the Irssi SILC client. Added
2383 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2385 * Added SCONNECT command to call the SILC's CONNECT command.
2386 Cannot use CONNECT directly since Irssi uses that internally.
2387 Affected file irssi/src/silc/core/silc-servers.c.
2389 Added ACTION local command. It is same as ME command but takes
2390 the channel as mandatory argument.
2392 Rewrote some of the Irssi's help files to suite for SILC
2395 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2397 * Added Makefile.defines[.in] that should for now on be included
2398 in all Makefile.am file in the source tree. That file includes
2399 all common compilation definitions for SILC source tree.
2401 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2403 * Minor changes to the ./prepare script to change the package
2404 name according the distribution name to the configure.in.
2406 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Created new distribution system. Added file `distributions'
2409 that defines all the distributions that can be created out of
2410 the SILC source tree. The ./prepare script now reads that
2411 file to determine how to prepare the distributions. The
2412 first argument to the ./prepare is the name of the distribution
2413 and second is the version of the distribution. If given
2414 without arguments it creates the default (toolkit) distribution
2415 with the default version (defined in ./prepare).
2417 All Makefile.am files that are subject to the distributions
2418 are now named as Makefile.am.pre. These are ./Makefile.am
2419 and lib/Makefile.am. Others may be changed later.
2421 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Added invite list, ban list, some key management and connection
2424 error message printing to module formats in the Irssi SILC client.
2426 * Added new silc_client_set_away_message to set the away message
2427 that is back to the person who sent private message. The
2428 affected file lib/silcclient/silcapi.h and the
2429 lib/silcclient/client_prvmsg.c.
2431 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2433 * Fixed the private message sending in the Irssi SILC client,
2434 added local command KEY to the Irssi SILC client.
2436 Added key management and key agreement message formats to the
2437 irssi/src/fe-common/silc/module-formats.[ch].
2439 Added USERS (alias WHO) printing, server/router operator
2440 indication and LIST command printing to the module formats.
2442 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Fixed channel joining notify handling, cumode notify handling
2445 from Irssi SILC client.
2447 * Added SILC specific module-formats to the Irssi SILC client so
2448 that SILC specific message hilighting, colors etc is possible.
2449 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2451 Added channel mode, channel user mode, actions, notices,
2452 whois and whowas printing to the the module-formats.c.
2454 * Fixed a bug in channel deletion in the server. The channel
2455 is not left to the cache even if the channel founder auth mode
2456 is set when there are no users anymore on the channel. Affected
2457 file silcd/server.c.
2459 * The silc_net_localhost now resolves the entire hostname including
2460 the domain name. Affected file lib/silcutil/silcnet.c.
2462 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Changed the ask_passphrase client operation to be ascynchronous.
2465 It has now a completion callback and a context that the
2466 application must call after it has got the passphrase from
2467 the user. Affected files lib/silcclient/silcapi.h,
2468 lib/silcclient/protocol.c, lib/silcclient/command.c and
2471 Added SilcAskPassphrase callback that the application calls
2472 to deliver the passphrase to the library.
2474 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2475 The public key verification and especially a certificate
2476 verification is asynchronous procedure.
2478 Added new SILC_SKE_STATUS_PENDING status to indicate the
2479 request is pending and a callback will be called to finalize
2482 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2483 indicate that remote end did not send its public key (or
2484 certificate), even though we require it. Added check for this
2485 condition in the SKE. This was a security bug, now fixed.
2487 Defined new SilcSKEVerifyCbCompletion callback that is called
2488 when the verification process is completed.
2490 The affected files lib/silcske/silcske_status.h and
2491 lib/silcske/silcske.[ch].
2493 * Changed the verify_public_key client operation to be async
2494 as well. Defined SilcVerifyPublicKey callback that is used to
2495 indicate the success of the public key verification process.
2497 Changed the server and client to use the new async client
2500 * Changed the Irssi SILC client's internal scheduler to be called
2501 twice as many times as it used to be. As a result the client
2502 should be a bit faster now. Affected file is
2503 irssi/src/silc/core/silc-core.c.
2505 * Added support to Irssi SILC client of asynchronous public key
2506 verification and passphrase inquiry. Affected file is
2507 irssi/src/silc/core/silc-core.c.
2509 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Do not say "You have left channel %s" in client library.
2512 Moved it to the application. Affected files are
2513 lib/silcclient/command.c and silc/client_ops.c.
2515 * Fixed silc_client_get_clients. Command context was not
2516 duplicated and was freed memory in the callback. Affected
2517 file lib/silcclient/idlist.c.
2519 * Do not say "you are now talking..." on JOIN command in the
2520 client library. The appliation must handle it.
2522 * Do not say ".. changed topic to" in command reply in the
2523 client libary. The application must handle it.
2525 * Fixed TOPIC command sending in the client library.
2527 * Fixed a memory leak in silc_client_command_free in the file
2528 lib/silcclient/command.c.
2530 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Imported a modified version of Irssi client to the source tree.
2533 The Irssi will be used to create a new client called
2534 Irssi SILC. Imported to irssi/.
2536 Added silc_core_init_finish function to the Irssi. Affected
2537 file irssi/configure.in.
2539 A lot changes in the Makefile.ams around the irssi tree.
2541 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Do not rehash if the new size is same as the old size of the
2544 hash table, in the silc_hash_table_rehash*. The affected file
2545 lib/silcutil/silchashtable.c.
2547 * Replaced hash_table_del_by_context calls from the server
2548 (when channel->user_list and client->channels) to the
2549 hash_table_del as it is sufficient and faster.
2551 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2553 * Added silc_hash_table_list, silc_hash_table_get and the
2554 SilcHashTableList structure to provide an alternative way to
2555 traverse the hash table. The affected files are
2556 lib/silcutil/silchashtable.[ch].
2558 * Changed the server's idlist routines to use the hash table
2559 routines to optimize the code.
2561 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Replaced the client entry's `channel' list and channel entry's
2564 `user_list' list to hash tables for optimized lookup. Changed
2565 the code to use the hash table interface around the code.
2566 Affected file lib/silcd/idlist.[ch].
2568 * Added `auto_rehash' boolean argument to the function
2569 silc_hash_table_alloc to indicate whether the hash table should
2570 auto-rehash when it thinks is appropriate time. It will
2571 increase the hash table size if the there is twice as much
2572 entries in the table than the size of the table, and will
2573 decrease the size if there are twice as less entries than
2574 the size of the table.
2576 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2580 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * silc_idcache_purge_by_context deletes the entry now by context
2583 as it is supposed to do. Affected file lib/silccore/idcache.c.
2585 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2586 client is not anymore valid (WHOWAS givens the info) and not
2587 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2589 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Removed the `data' and `data_len' arguments from the ID Cache
2592 interfaces and added `name' argument. ID Cache does not handle
2593 anymore the binary data only a names associated with given ID.
2595 * When hashing a Client ID with silc_hash_id the entire ID is
2596 not hashed anymore, instead only the hash of the Client ID is
2597 hashed. This way we can access the Client ID from the cache
2598 with Client ID but with the hash of the ID (which is a hash of
2599 the nickname) as well without any difference in performance.
2601 Added also silc_idcache_find_by_id_one_ext to do one on one
2602 searching when we have the actual ID. Added also function
2603 silc_hash_client_id_compare. The affected files are
2604 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2606 * When hashing the name associated with a ID it is always done
2607 in lowercase. This way we can access the cache without worrying
2608 about case-sensitivity, even though, for example nicknames are
2611 * Fixed a bug in server with channel message sending. It put
2612 wrong ID type as destination ID. The affected file
2613 silcd/packet_send.c.
2615 * silc_idcache_del_by_context now deletes from all hash tables
2616 by context. Affected file lib/silccore/idcache.c.
2618 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2620 * Changed the client library to use the new ID Cache interface.
2621 Changes around the source tree.
2623 * Added silc_hash_table_rehash_ext to rehash with specific
2624 hash function. Affected file lib/silcutil/silchashtable.[ch].
2626 * Added silc_hash_string_compare to compare two strings in the
2627 hash table. Affected file lib/silcutil/silcutil.[ch].
2629 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Added new function silc_idcache_del_by_context into the
2632 lib/silccore/idcache.[ch].
2634 * Changed the server's ID list routines to use the new ID Cache
2635 interface. Changes around the source tree.
2637 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Added silc_hash_table_del[_by_context]_ext functions in to the
2640 lib/silcutil/silchashtable.[ch].
2642 Removed silc_hash_table_find_all* routines and added new
2643 silc_hash_table_find_foreach to replace them.
2645 Added silc_hash_table_replace_ext function as extended
2646 replacing function. Separated the simple hash table interface
2647 from the extended hash table interface in the file
2648 lib/silcutil/silchashtable.h.
2650 * Fixed minor bugs and changed it to use some of the new
2651 hash table functions in lib/silccore/idcache.c
2653 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added new function silc_hash_table_find_all to return all keys
2656 in the hash table by the specified key. As the hash table is
2657 collision resistant it also makes it possible to have several
2658 duplicate keys in the hash table. This function may be used to
2659 find all of the keys from the hash.
2661 Added user_context arguments to the SilcHashFunction,
2662 SilcHashCompare and SilcHashDestructor to deliver user specified
2665 Added new fuctions silc_hash_table_find[_all]_ext to do
2666 extended lookup with specified hash and compare functions and
2667 specified user contexts.
2669 Added new function silc_hash_table_add_ext to add the key
2670 with specified hash function and user context.
2672 Added new function silc_hash_table_foreach to traverse all
2673 entrys in the hash table. Added SilcHashForeach callback
2676 Added new function silc_hash_table_del_by_context to delete
2677 the entry only if the context associated with the key matches.
2679 Affected files are lib/silcutil/silchashtable.[ch].
2681 * Removed silc_hash_[server/client/channel]_id and added just
2682 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2683 silc_hash_id_compare to compare two ID's using as the hash table
2684 comparison function. Added also silc_hash_data to hash
2685 binary data and silc_hash_data_compare to compare it.
2687 * Removed silc_idlist_find_client_by_hash as it is not needed
2688 anymore. Affected file silcd/idlist.[ch].
2690 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2691 to use internally the SilcHashTable. The new ID Cache is a lot
2692 faster than the old one. Some of the ID Cache interface was also
2693 rewritten and obsolete and stupid functions were removed.
2695 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Added entry_count field to the SilcHashTable to keep the number
2698 of the entries in the table. Implemented the function
2699 silc_hash_table_rehash. Added new function
2700 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2702 Fixed a minor bug in silc_hash_table_free.
2704 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2705 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2706 into the lib/silcutil/silcutil.[ch].
2708 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Implemented a collision resistant hash table into the
2711 lib/silcutil/silchashtable[ch]. See the header and the source
2712 for the SilcHashTable API.
2714 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2716 * Merged dotconf version 1.0.2 into lib/dotconf.
2718 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Do not compile anything in lib/silcsim/* if the SIM support
2721 is not enabled. The tree should now compile without problems
2724 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2726 * Compiled the SILC under cygwin. Compiled and tested briefly
2727 without problems. More tests needed. The SIMs didn't compile
2730 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2732 * Fixed possible crash in silc_get_username in the
2733 lib/silcutil/silcutil.c.
2735 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Fixed a va_arg in silc/client_ops.c.
2739 * Oops, RC5 routines were named AES and caused some problems
2740 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2742 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Added new SilcIDIP structure into the lib/silccore/id.h and
2745 replaced the old `ip' fields from all SILC ID's to that type.
2746 This is a step towards IPv6 support.
2748 The silc_id_get_len takes now the ID as an extra argument.
2749 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2750 both IPv4 and IPv6 based ID's.
2752 The affected files are lib/silccore/id.[ch] and other files
2753 around the tree using these routines.
2755 * Removed the ID length arguments in server from various
2756 silc_server_send_notify_* routines -> they are not needed
2759 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Fixed memory leak in silc_encode_pem_file in the file
2762 lib/silcutil/silcutil.c.
2764 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Check minor version as well in the SKE. Affected files are
2767 silcd/protocol.c and lib/silcclient/protocol.c.
2769 * Added --identifier option to the server so that an identifier
2770 can be when creating the public key for the server. Affected
2771 file is silcd/silcd.c.
2773 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2774 lib/silccrypt/silcpkcs.c.
2776 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Register default ciphers and stuff when using -C option with
2779 the server. Affected file sildc/silcd.c.
2781 * Put back the servers public key filename format, it is better
2782 than the new one. For now, the client keys are saved with the
2783 new filename format. The affected file silc/client_ops.c.
2785 * Implemented the Cipher API for the rest of the ciphers that
2786 did not implement it or implemented it the wrong way.
2788 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Register default ciphers and stuff when using the -S option
2791 in the client. Affected file silc/silc.c. Same also when
2792 creating new key pair with -C option.
2794 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Fixed the silc_verify_public_key client operation function to
2797 save the public keys differently. The fingerprint is now
2798 used as filename and not the hostname. This way also the
2799 client keys are saved uniquely and not with hostnames. The
2800 affected file is silc/client_ops.c.
2802 * Trimmed the silc_hash_fingerprint function to remove extra
2803 whitespaces from the end of the fingerprint. The affected
2804 file is lib/silccrypt/silchash.c.
2808 * Added silc_cipher_register_default function to register all
2809 default ciphers. It can be used when configuration files
2810 does not exist and the application does not want any specific
2811 ciphers in any specific order.
2813 The SilcDList is now used as silc_cipher_list dynamically
2814 allocated cipher list. Removed the static list all together
2815 and now all ciphers must be allocated to the dynamic list.
2816 The silc_cipher_alloc routine was changed to check only the
2819 All silc_cipher_* routines that used to return int returns
2822 The affected files lib/silccrypt/silccrypt.[ch].
2824 * The same thing was done to silc_hash_* as for silc_cipher_*
2825 routines. Affected files lib/silccrypt/silchash.[ch].
2827 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2828 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2829 Added also silc_pkcs_[un]register[_default] functions.
2830 Removed the data_context from the PKCS API.
2832 * Added silc_hmac_register_default function to register default
2833 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2834 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2835 to unregister all hmacs at once.
2837 * Register the default ciphers, hash functions, PKCSs and HMACs
2838 if client's configuration file does not exist. The affected
2841 * The client did not load the hash functions from the SIM
2842 modules at all. Added support for this. Affected file is
2843 silc/clientconfig.c.
2845 * When decoding public key with silc_pkcs_public_key_decode, check
2846 the supported algorithm only if PKCS are registered. Affected
2847 file lib/silccrypt/silcpkcs.c. The same was done with the
2848 silc_pkcs_private_key_decode.
2850 * Fixed the SILC List routines to keep the list always in order.
2851 It used to change the list's order when traversing the list but
2852 not it preserves the order. Affected file lib/trq/silclist.h.
2854 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Added the client library to use the SilcSocketConnection's
2857 reference counter (by silc_socket_dup) to prevent the bug that
2858 the socket object may be freed underneath async operation.
2860 * The name resolv library checking fixes in the configure.in.pre.
2863 * Created new version of the protocol drafts for future
2864 development. The -03 drafts are the ones that will be changed
2865 in the trunk now and the -02 will remain as they are.
2867 * Send list of CUMODE notifys to the router when announcing
2868 the channel users to the router. Affected file silcd/server.c.
2869 If the router receiving channel founder CUMODE for a channel
2870 that already has channel founder it will send CUMODE notify
2871 to the sender to remove the channel founder rights from the
2872 announced client. Affected file silcd/packet_receive.c.
2874 * The CUMODE notify may now use Server ID as well as the entity
2875 who changes the mode. Updated protocool specs.
2877 * Updated INSTALL and README files.
2879 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * New web pages in the http://silc.pspt.fi. The pages was
2886 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Implemented the [DenyConnectin] config section in the server.
2889 Added silc_server_config_denied_conn to check whether incoming
2890 connection is denied. Affected file silcd/serverconfig.[ch].
2892 * Do not check the ports when checking the incoming configuration
2893 data if the port is 0, meaning any. Affected file is
2894 silcd/serverconfig.c.
2896 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Fixed buffer overflow in silc_string_compare in the file
2899 lib/silcutil/silcutil.c.
2901 * Fixed double free in silc_server_command_leave in the file
2904 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Fixed the version checking in the server. Affected file is
2909 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Fixed the configuration data fetching when accepting new
2912 connections in the server. Affected file silcd/server.c.
2914 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Added `sender_entry' argument to the function
2917 silc_server_packet_relay_to_channel so that we can check
2918 whether some destination actually belongs to the same route
2919 the sender belongs (ie, we must not resend the packet to the
2920 sender). Affected file silcd/packet_send.[ch].
2922 * Added `servername' field to the SilcClientEntry in the server
2923 to hold the name of the server where client is from. Affected
2924 file is silcd/idlist.h.
2926 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Moved the channel message encrypting in the router betwen
2929 router connections from silc_server_channel_message to the
2930 silc_server_packet_relay_to_channel since we want to check
2931 whether we have anybody channel before encrypting anything.
2932 Affected files silcd/packet_[receive/send].c.
2934 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Fixed the [AdminConnection] server config section to support
2937 multiple entries. Affected file silcd/serverconfig.c.
2939 * Added support into the server to check the validity of the
2940 incoming connection before executing any KE or authentication
2943 * The connection configuration is now saved to the KE and
2944 connection auth protocol contexts and not fetched anymore in
2945 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2947 * The local hosts listenning address and port is also resolved
2948 now when starting the server. We want to have the socket object
2949 to include the real address and port for the listener. Added
2950 new function silc_net_check_local_by_sock into the files
2951 lib/silcutil/silcnet.[ch].
2953 * Fixed a broadcast bug in server -> do not broadcast if we
2956 * Fixed a routing bug. Do not route broadcast packets ever.
2957 Broadcast packets must be processed always and not routed since
2958 they may be destined to some other host than yourself and thus
2959 would get routed without no good reason. Affected file is
2962 * Added function silc_server_config_is_primary_route to check
2963 whether primary router connection has been configured (a router
2964 configuration that we are initiating). If there is not, we
2965 will assume that there is only two routers in the SILC network
2966 and we will use the incoming router connection as our primary
2967 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2969 * Changed the order of the broadcasting. Broadcast _after_ the
2970 packet has been processed not before. Affected file is
2973 * Fixed a [ClientConnection] parsing bug. The port was never
2974 parsed correctly thus resulting to port 0. Affected file
2975 silcd/serverconfig.c.
2977 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2978 argument and did not set the broadcast packet flag. Affected
2979 file silcd/packet_send.c. Fixed same bug in the function
2980 silc_server_send_notify as well.
2982 * If we receive NEW_ID packet for our own ID in the server, ignore
2985 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Removed the nickname from the Private Message Payload.
2990 Updated the code and the protocol specs.
2992 * Updated protocol specs for submitting to the IETF.
2994 * Tweaked the Random Number Generator a bit. Affected file
2995 lib/silccrypt/silcrng.c. Exported a new function
2996 silc_rng_[global]_add_noise which can be used to add more
2999 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Do not parse packets with different timeout when protocol
3002 is active -> may cause problem with rekey. Affected file
3005 * When server receives signoff notify it must not create
3006 new channel key if the client is on any channels since the
3007 sender of the signoff notify will create it.
3009 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Added printing of error messages during SKE protocol from the
3012 failure packet sent by server during SKE. Affected file
3015 * Removed the client's failure_callback handling with timeout
3016 and handle it immediately when received.
3018 * The SKE library returned wrong type in SUCCESS and FAILURE
3019 packets. They must be 32 bit MSB not 16 bit MSB.
3021 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Ok, rewrote the logic of the re-key and now it seems to work.
3024 I tested it on high traffic with frequent re-keys without
3025 problems. Added hmac_receive (and renamed hmac to hmac_send)
3026 in SilcClientConnection in lib/silcclient/client.h and
3027 in SilcIDListData in silcd/idlist.h. Also, removed the
3028 SilcPacketParserContext's cipher and hmac fields as they are
3029 not needed anymore and actually caused some problems when
3030 the ciphers and hmac's changed underneath the packet parser.
3032 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * If re-key protocol is active then process the incoming packets
3035 synchronously since we must assure that icoming packets encrypted
3036 with the old key is processed before the new keys is set to
3037 use. This is true other packets than for REKEY packets.
3038 Affected file silcd/server.c. The same was done to client library
3039 as well, affected file lib/silcclient/client.c.
3041 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Fixed bug in client and server to accept the force send if
3044 the packet is send from silc_[server/client]_packet_process
3045 function. Otherwise the packets are never delivered, oops.
3047 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Disable force sending of packets when REKEY protocol is active.
3050 We must assure that no packet is sent directly when rekey is
3051 performed. All packets must be sent through packet queue.
3052 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3053 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3054 function is silc_[server/client]_packet_send_real to check
3057 * Replaced the SIM paths from example config files to
3058 /usr/local/modules. Also, make install creates now
3059 /usr/local/silc/logs directory to hold all the SILC server
3062 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3064 * Made the configure.in.pre work on Solaris. Patch by salo.
3066 * Made all ciphers compatible with non-x86 machines. Defined
3067 CBC mode macros into lib/silccrypt/ciphers_def.h.
3069 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Fixed the make install.
3073 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * When MAC computation fails the silc_packet_decrypt returned 0
3076 even though it was supposed to return -1. Fixed this. The
3077 affected file is lib/silccore/silcpacket.c.
3079 * Do not replace the config files in /etc/silc (in make install)
3080 if they already exist. Affected file ./Makefile.am.
3082 * Do not send re-key packets immediately but through packet queue.
3083 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3085 * Changed silc_net_check_host_by_sock to return FALSE if the
3086 IP/DNS could not be resolved. Though, it returns the IP address
3087 now even if it could not resolve it (but returns also FALSE).
3088 Affected file lib/silcutil/silcnet.[ch].
3090 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Added silc_pkcs_decode_identifier to decode the public key's
3093 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3094 Added also silc_pkcs_free_identifier. Added also new context
3095 SilcPublicKeyIdentifier.
3097 * Added -S option to the silc client. It is used to dump the
3098 contents of the specified public key file.
3100 * Changed the PKCS api to return the public key length when
3101 setting the public key.
3103 * Fixed a fatal bug in the public and private key file loading.
3104 Affected file lib/silccrypt/silcpkcs.c.
3106 * Execute the packet parsing for client with zero (0) timeout
3107 if the protocol is active. Affected file silcd/server.c.
3109 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Made the key generation options to the silcd program. Added
3112 -C option, equivalent to client's option.
3114 * Added new [ServerKeys] config section to the server. It
3115 configures the server's public and private key.
3117 * Defined generic Public Key Payload into the protocol
3118 specification to send specific type of public keys and
3121 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3122 public key or certificate.
3124 * Implemented the GETKEY command to the server and to the
3125 client library and on user interface.
3127 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Made preliminary `make install' work.

3146 state of the protocol. Affected file is
3147 lib/silccore/silcprotocol.[ch].
3149 * Added the re-key support with and without PFS to the client
3150 library. Re-key is performed once in an hour, by default.
3152 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3153 Added silc_client_rekey_callback and silc_client_rekey_final.
3154 Affected files are lib/silcclient/protocol.[ch] and

3158 SilcClientConnection structure; not needed. Affected file is
3159 lib/silcclient/client.h.
3163 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Do not ask whether user wants to use the negotiated private key
3166 for private messages, just use it. Affected file is
3167 silc/local_command.c.
3169 * Added `send_enc_key' and `enc_key_len' fields to the
3170 SilcIDListData structure since they are needed in the re-key
3171 phase. Affected file is silcd/idlist.[ch].
3173 * Implemented the simple re-key protocol into the server.

3190 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3191 int64 of at least the xintXX size. If void * is less that 4
3192 bytes uint32 * will be used. Defined bool as boolean.
3194 * Changed _ALL_ unsigned long and unsigned int to uint32,
3195 unsgined short to uint16 in the source tree.
3197 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3198 not handle clients that has entry->data.registered == FALSE.
3199 They are not in the network anymore. Affected file is
3202 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3204 * Implemented the sending of the SERVER_SIGNOFF notify in the
3205 server. Affected file is silcd/server.c.
3207 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3208 Added also silc_notify_payload_encode_args into the

3211 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3212 Affected file silcd/packet_receive.c.
3214 * Implemented the SERVER_SIGNOFF notify handling in the client
3215 library. Affected file lib/silcclient/client_notify.c. Also,
3216 implemnted the printing of the SERVER_SIGNOFF info to the
3217 application. Affected file silc/client_ops.c.
3219 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3220 if the deleting was successful. Affected file silcd/idlist.[ch].
3222 * Added support for public key authentication in the connection
3223 authentication protocol in the client library. Affected file
3224 lib/silcclient/protocol.c.
3226 * Changed the server's silc_idlist_get_clients_by_* interface
3227 to support already allocated array so that new entries may be
3228 added to pre-allocated array. Affected file silcd/idlist.[ch].
3229 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3230 and command replies.
3232 * All command reply functions in the server now calls the
3233 pending command callback even if error occured. This way the
3234 error will be delivered to the client as well. Affected files
3235 silcd/command.c and silcd/command_reply.c.
3237 * Fixed INFO command to return local server's info if no server
3238 was provided. Affected file lib/silcclient/command.c.
3240 * Removed RESTART command for good. Updated the code and the
3243 * Rewrote parts of the task system. It is a bit simpler now.
3244 Removed unsued task priorities. The affected files are
3245 lib/silcutil/silctask.[ch].
3247 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3249 * Moved the USERS printing from the library to the application.
3250 Affected files lib/silcclient/command.c and silc/client_ops.c.
3252 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Added channel key re-key support. The re-key is perfomed
3257 only by the router and is done once in an hour. Added `rekey'
3258 field to the SilcChannelEntry in the server. Affected files
3259 silcd/server.c and silcd/idlist.h.
3261 * Added silc_task_unregister_by_context into the file
3262 lib/silcutil/silctask.[ch].
3264 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Added SILC_UMODE_GONE mode to indicate when the client is not
3267 present in the SILC network. Added also support to the local
3268 command AWAY that will set this mode. Added support of showing
3269 "xxx is gone" in WHOIS command. The USERS command shows the
3270 gone status as well.
3272 * Fixed setting server and router operator privileges in the
3273 server's UMODE command. Affected file silcd/command.c.
3275 * Merged the SKE KE1 and KE2 payloads into one payload. The
3276 new KE payload is equivalent to the old KE2 payload.
3278 Cleaned up the SKE Start Payload parsing. It now uses the
3279 simple buffer unformatting to do the parsing. A lot faster
3282 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3283 to the SKE that is used to indicate whether both of the SKE
3284 parties should perform authentication. By default only the
3285 responder performs authentication. By setting this flag also
3286 the initiator must do authentication. By default it is unset
3287 since in normal SKE case, client to server connection, only
3288 the responder should do authentication. When doing SKE between
3289 two clients both should perform authentication. Updated the
3290 code and the protocol specs.
3292 * A little fix to IDENTIFY command in the server. Search the
3293 client first by hash not nickname. Affected file is
3296 * Fixed the silc_client_close_connection to support closing
3297 the client to client connections wihtout deleting too much
3298 data. Affected file lib/silcclient/client.c.
3300 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3301 are received if protocol used to be active but is not anymore
3302 the application would crash due to NULL pointer dereference.
3303 Affected files silcd/server.c and lib/silcclient/client.c.
3305 * Added `hash' field to the SilcClientConnection to include
3306 the hash function negotiated in the SKE protocol.
3308 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3309 to set the channel founder authentication data. A client can
3310 claim the founder rights later by providing the authentication
3311 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3312 This way the channel founder can regain the channel founder
3313 privileges even it is left the channel. This works only on
3314 local server and the client must be connected to the same
3315 server to be able to regain the founder rights. Updated the
3316 protocol specs accordingly.
3318 Added support to the CMODE command in the client to set the
3319 founder auth data. Read the README to see how to set it.
3321 Added support to the CUMODE command to claim the founder
3322 rights. Read the README to see how to do it.
3324 Added support for the founder authentication to the Channel
3325 Entry in the server. Affected file silcd/idlist.h.
3327 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3328 server's CMODE command. Affected file silcd/command.c.
3330 * Added the following new functions into lib/silccore/silcauth.[ch]:
3331 silc_auth_get_method and silc_auth_get_data.
3333 * The server now saves the remote hosts public key to the
3334 SilcIDListData pointer. Affected file silcd/protocol.c.
3336 * The normal server now does not remove the channel entry from
3337 the cache if the founder authentication data is set. It used
3338 to remove it if the founder was the last one on the channel on
3339 the server and left the channel. The auth data is saved and
3340 if the channel is re-joined later the old entry is used with
3341 the old auth data. Affected files silcd/command_reply.c and
3344 * Removed the `pkcs' field from the SilcIDListData structure
3345 in the server; it is not used. Affected file silcd/idlist.h.
3347 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Fixed packet processing on slow links. Partial packets were
3350 never re-processed because the incoming data buffer was cleared
3351 by the application. Application must not directly clear the
3352 sock->inbuf, the packet processing routines handle it. Fixed
3353 this in client library and in server.
3355 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Fixed the WHOIS and IDENTIFY send reply function to really
3358 check whether to send list or just one entry. Affected file
3361 * Cleaned up the LEAVE command's channel key distribution. The
3362 affected file silcd/command.c.
3364 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3365 can enforce the channel mode as well. In that case the ID
3366 includes the ID of the server. The code now enforces the
3367 mode change if the router have different mode than the server.
3369 * The notify client operation with CMODE_CHANGE notify can now
3370 return NULL client_entry pointer if the CMODE was not changed
3371 by client. Application must check for this.
3373 * Added <Server ID> argument to INFO command to support server
3374 info fetching by Server ID.
3376 * Added silc_server_announce_get_channel_users to get assembled
3377 packets of channel users of the specified channel. Affected
3378 file silcd/server.[ch].
3380 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3381 was freed underneath the ID Cache.
3383 * Re-announce clients when the server received CHANNEL_CHANGE
3384 notify from the router. Affected file silcd/packet_send.c.
3386 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3389 crashed since it did not handle the fact that there is no cipher
3390 called "3" and didn't check the error condition. Now fixed.
3392 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3393 flag. It can be used to send message requests.
3395 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Implemented the RESTART command in the client.
3399 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3400 notice type messages. Added notice printing to the user
3403 * The channel keys are not re-generated if the channel's mode
3404 is PRIVKEY, ie private key on the channel exists. Affected
3405 files silcd/server.c and silcd/command.c.
3407 * Fixed a little bug in channel message delivery when channel
3408 private keys are set in the server. Affected file is
3409 silcd/packet_send.c.
3411 * Changed the setting on channel->on_channel = TRUE from the
3412 silc_client_save_channel_key to the JOIN command reply. The
3413 key payload is not received if the private channel key is set.
3414 Affected file lib/silcclient/command_reply.c and the
3415 lib/silcclient/client_channel.c.
3417 * When the CMODE_CHANGE notify is sent and the channel private
3418 key mode is removed the channel key must be re-generated in
3419 other cells as well. Added this support for the router in the
3420 silcd/packet_receive.c.
3422 * Added new local command NOTICE to send notice message on
3423 channel. Affected file silc/local_command.[ch].
3425 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Added new local command ME to the client. It is used to send
3428 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3429 some action. Affected file silc/local_command.[ch].
3431 * Changed channel_message and private_message client operations
3432 to deliver the message flags to the application. Added also
3433 the `flags' arguments to the silc_client_send_channel_message
3434 and silc_client_send_private_message functions. Affected file
3437 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Redefined the Private Message Payload to support private message
3440 keys and to support the new private message flags. Updated
3441 the protocol specs. Flags makes it possible to have for example
3442 CTCP style messages.
3444 * Added new type SilcPrivateMessagePayload and defined an API
3445 for it in the lib/silcclient/silcprivate.[ch].
3447 * Tested private message private keys successfully. Tested the
3448 private message key set, unset and list commands with the new
3451 * Redefined the Channel Message Payload to include the channel
3452 message flags (equal with private message flags) to support
3453 for example CTCP style messages.
3455 * Defined some of the message (for channel and private message)
3456 flags. Updated the protocol specs and added the flags to the
3457 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3459 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3461 * Added SilcKeyAgreementStatus type to the key agreement routines
3462 to indicate the current status and error if one occured.
3463 The status types are defined in the lib/silcclient/silcapi.h.
3465 * Added new local command KEY that is used to set and unset private
3466 keys for channels, set and unset private keys for private messages
3467 with remote clients and to send key agreement requests and
3468 negotiate the key agreement protocol with remote client. The
3469 key agreement is supported only to negotiate private message keys,
3470 it currently cannot be used to negotiate private keys for channels,
3471 as it is not convenient for that purpose.
3473 * Fixed a minor pending callback setting bug in the function
3474 silc_client_get_client_by_id_resolve, now the function works.
3475 Affected file lib/silcclient/idlist.c.
3477 * Added function silc_net_get_local_port to get local bound
3478 port by socket. Added to lib/silcutil/silcnet.[ch].
3480 * Added `sockets' and `sockets_count' fields to the SilcClient
3481 object. They hold the sockets of the listenning sockets in
3482 the client. Listenning sockets may be for example the key
3483 agreement server. Affected file lib/silcclient/client.[ch].
3484 Added functions the silc_client_add_socket and the
3485 silc_client_del_socket. They are exported to the application
3488 * Added ~./silc/clientkeys to support other client's public keys.
3490 * Renamed verify_server_key client operation to verify_public_key
3491 and added one argument to indicate the type of the connection
3492 (server, client etc.).
3494 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * Added silc_server_connection_auth_request to handle the
3497 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3498 silcd/packet_receive.[ch].
3500 * Added silc_server_send_connection_auth_request into the
3501 silcd/packet_send.c to send the connection auth request packet.
3503 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3506 * Fixed the public key authentication in responder side in the
3507 server. The `auth_data' pointer includes the SilcPublicKey
3508 not the path to the public key. Affected file silcd/protocol.c.
3510 * Implemented the public key authentication in the initiator side
3511 in the server. Affected file silcd/protocol.c.
3513 * Removed the [RedirectClient] config section from the server
3514 configuration. Is not needed and I don't want to implement it.
3516 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Cleaned up the CMODE command in the server. It now works
3519 correctly and supports all the modes defined in the protocol.
3520 Affected file is silcd/command.c.
3522 * Added `hmac_name' field to the SilcChannelEntry in the server
3523 to hold the default HMAC of the channel. It can be set when
3524 creating the channel (with JOIN command). Affected files
3527 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3528 type to indicate the change of the current cipher and hmac
3529 on the channel. Client can safely ignore the <cipher> argument
3530 (if it chooses to do so) since the CHANNEL_KEY packet will
3531 force the channel key change anyway. The <hmac> argument is
3532 important since the client is responsible of setting the new
3533 HMAC and the hmac key into use.
3535 * Fixed the CMODE command in the client library as well.
3537 * Tested CMODE command in router environment successfully.
3539 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Show the version of the remote client (or server) when connecting
3542 to the server. It is logged to the log file. Affected file
3543 is silcd/protocol.c.
3545 * Fixed the KILLED notify handling in the client library. The
3546 client must be removed from all channels when receiving the
3549 Also, do not remove the client entry when giving the KILL
3550 command but when the KILLED notify is received.
3552 * Removed silc_idlist_find_client_by_nickname from the server.
3553 Not needed anymore. Affected files silcd/idlist.[ch].
3555 * Implemented the CHANNEL_CHANGE notify type handling to the
3556 server. Affected file silcd/server.c.
3560 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Added silc_server_send_notify_invite to send the INVITE
3563 notify between routers.
3565 * Implemented the INVITE command correctly to the server.
3567 * Implemented the INVITE notify type handling in the server.
3569 * Implemented the INVITE command to the client library and on the
3572 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added function silc_server_get_client_resolve to find the
3575 client entry by ID from all ID lists and then resolve it
3576 (using WHOIS) if it cannot be found. Affected file is
3579 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Implemented the BAN command to the client library.
3583 * The JOIN command in the server now checks the invite list
3586 * Changed the silc_command_reply_payload_encode_va and the
3587 silc_command_payload_encode_va to support that if argument is
3588 NULL it ignores and checks the next argument. Affected file
3589 lib/silccore/silccommand.c.
3591 * Added silc_server_send_notify_ban to send the BAN notify
3592 type between routers.
3594 * Chaned the silc_notify_payload_encode to support that if
3595 argument is NULL it ignores and checks the next argument.
3596 Affected file lib/silccore/silcnotify.c.
3598 * Tested ban lists in router environment successfully.
3600 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Implemented BAN command to the server, in silcd/command.[ch].
3604 * Removed the BAN and INVITE_LIST modes from the CMODE command
3607 * Added function silc_string_match to regex match two strings.
3608 Affected files lib/silcutil/silcutil.[ch].
3610 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Redefined parts of the SilcChannelEntry in the server to support
3613 the new ban and invite lists.
3615 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Redefined the INVITE command. The same command can be used to
3618 invite individuals to the channel but also to manage the invite
3619 list of the channel (to add to and remove from the invite list).
3620 Updated the protocol specs.
3622 * Added new command SILC_COMMAND_BAN that can be used to manage
3623 the ban list of the channel. Updated the protocol specs.
3625 * Removed the channel modes: the SILC_CMODE_BAN and the
3626 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3627 in the CMODE command. The equivalent features are now available
3628 using INVITE and BAN commands. Updated the protocol specs.
3630 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3631 in the network about change in the current ban list. The notify
3632 type is not used by the client.
3634 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3635 support the invite lists.
3637 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Added new function silc_string_regexify that converts string
3640 including wildcard characters into regex string that can
3641 be used by the GNU regex library. Added into the file
3642 lib/silcutil/silcutil.[ch].
3644 Added silc_string_regex_combine to combine to regex strings
3645 into one so that they can be used as one regex string by
3646 the GNU regex library. Added into the file
3647 lib/silcutil/silcutil.[ch].
3649 Added silc_string_regex_match to match two strings. It returns
3650 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3652 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Imported GNU regex to the soruce tree into lib/contrib.
3655 Fixed some compiler warning from the regex.c.
3657 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Fixed MOTD command in the server to work in router environment.
3661 * Fixed the MOTD command in the client library to support
3662 the server argument in the command.
3664 * Added `nickname_len' argument to the silc_idlist_add_client
3665 in the server, as the `nickname' argument may be binary data
3668 * Added silc_idlist_get_channels to return all channels from
3671 * Implemented LIST command to the server. Affected file is
3674 * Implemented the LIST command to the client library and on the
3677 * Added [<user count>] argument to the LIST command reply.
3678 With private channels the user count is not shown.
3680 * Updated TODO and README.
3682 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * The client entry's data.registered must be TRUE even with
3685 global client entry on global client list. The data.registered
3686 is used to check whether the client is anymore in the network,
3687 for example with WHOWAS command so it must be valid.
3689 * Fixed the WHOWAS command in the server. It now actually works
3690 in router environment. Added function into silcd/command_reply.c
3691 silc_server_command_reply_whowas_save.
3693 * Added silc_idlist_purge function to the silcd/idlist.c
3694 to periodically purge the ID Cache.
3696 * Fixed INFO command in the server. It works now in router
3697 environment. Added <server name> argument to the INFO command
3698 reply. Updated the protocol specs.
3700 * Fixed minor bug in silc_idcache_purge to not purge if the
3701 expire value is zero.
3703 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3704 they were buggy because of the WHOWAS information.
3706 * Fixed local command MSG to handle the async resolving of
3707 the remote client properly. It used to fail the first MSG.
3708 Affected file silc/local_command.c.
3710 * Added `data_len' field to SilcIDCache context.
3712 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Update TODO. Todo in commands in the server.
3716 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3719 used by routers as broadcast packet to inform other routers
3720 about the changed user mode.
3722 Implemented the notify handling in the server. Affected file is
3723 silcd/packet_receive.c. Added the function
3724 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3726 * Added new generic Channel Payload and deprecated the New Channel
3727 Payload. The New Channel Payload is now the generic Channel
3730 * Added new argument `mode' to the silc_server_send_new_channel
3731 as it is required in the Channel Payload now.
3733 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3734 and created a new and real SilChannelPayload to represent the
3735 new generic Channel Payload. Implemented the encode/decode
3736 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3738 * Added silc_server_get_client_channel_list to return the list
3739 of channels the client has joined for WHOIS command reply.
3740 Affected file silcd/server.[ch].
3742 * Implemented the channel list sending in the WHOIS command reply
3743 in server and in the client.
3745 Implemented the channel list displaying on the user interface
3746 as well. Affected file silc/client_ops.c.
3748 * Added silc_channel_payload_parse_list to parse list of Channel
3749 Payloads. It returns SilcDList list of SilcChannelPayloads.
3750 Client for example can use this function to parse the list of
3751 channels it receives in the WHOIS command reply. The caller
3752 must free the list by calling silc_channel_payload_list_free.
3753 Affected files lib/silccore/silcchannel.[ch].
3755 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Added one new argument <user mode> to the WHOIS command reply
3758 to return the mode of the user in SILC. Updated the protocol
3761 Implemented it to the server and client.
3763 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Fixed the mode printing on the user interface on joining.
3766 Affected file silc/client_ops.c.
3768 * Implemented the UMODE command and user modes in general to the
3769 client library and to the user interface.
3771 * Implemented the UMODE command to the server.
3773 * The server now sends UNKNOWN_COMMAND error status if client sends
3774 unknown command. Affected file silcd/command.c.
3776 * All server commands now handle the command identifier the right
3777 way when sending the command reply to the client. The client can
3778 use to identify the command replies with the identifier.
3780 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Added silc_server_get_client_route to resolve the route to
3783 the client indicated by the client ID. Affected file is
3786 * Added silc_server_relay_packet as general function to relay
3787 packet to arbitrary destination. This deprecates functions
3788 like _send_private_message_key, _relay_notify etc. Affected
3789 file is silcd/packet_send.[ch].
3791 Removed silc_server_send_key_agreement,
3792 silc_server_send_private_message_key and
3793 silc_server_packet_relay_notify functions from the file
3794 silcd/packet_send.[ch].
3798 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3799 server. Affected file silcd/packet_receive.[ch].
3801 * Implemented the KILL command to the client. Implemented the
3802 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3803 Affected files lib/silcclient/command[_reply].c and
3804 lib/silcclient/client_notify.c. Implemented the KILL notify
3805 printing in the user inteface.
3807 * Fixed a lot silc_parse_nick memory leaks from the client
3808 library in the file lib/silcclient/command.c.
3810 * Changed the silc_server_send_notify_on_channels's `sender'
3811 argument from SilcSocketConnection to SilcClientEntry to
3812 check the sender as entry and not as connection object and not
3813 to send to the client provided as argument. The affected file
3814 is silcd/packet_send.[ch].
3816 * The notify packets that are destined directly to the client used
3817 to not to be processed by the server. Now changed that and the
3818 server processes all notify packets. After relaying the packet
3819 to the client the notify packet is processed in the server.
3821 * The silc_server_free_client_data now checks whether there is
3822 pending outgoing traffic for the client and purges the data to
3823 the network before removing the client entry.
3825 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3828 an client is killed from the SILC Network. Updated the protocol
3831 Added new function silc_server_send_notify_killed to the
3832 silcd/packet_send.[ch].
3834 * Added function silc_server_packet_relay_notify to relay notify
3835 packets that are destined directly to a client. In this case
3836 the server does not process the notify packets but merely relays
3837 it to the client. Affected file silcd/packet_send.[ch].
3839 Added also silc_server_packet_process_relay_notify to check
3840 whereto relay the notify. Affected file is
3841 silcd/packet_receive.[ch].
3843 * Implemented the KILL command to the server.
3847 * Added the backup schema desgined last fall to the protocol
3848 specs for everyone to see. The specification is in the
3849 *-spec-xx.txt draft and the packet type definitions for the
3850 backup routers is in *-pp-xx.txt draft. Thusly, added also
3851 new packet type SILC_PACKET_CELL_ROUTERS.
3853 * A big security problem in the implementation discovered. The
3854 signoff of an client did not cause new channel key generation
3855 which it of course should've done. The channel keys must be
3856 always re-generated when client leaves (or signoffs) the channel.
3857 The silc_server_remove_from_channels funtion now handles
3858 the channel key re-generation.
3860 * Added `sender' argument to the silc_server_send_notify_on_channels
3861 to not to send the client provided as argument. Affected file
3862 silcd/packet_send.[ch].
3864 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Implemented OPER and SILCOPER commands into the server and
3869 * Added silc_auth_verify and silc_auth_verify_data to verify
3870 the authentication directly from the authentication payload.
3871 It supports verifying both passphrase and public key based
3872 authentication. Affected file lib/silccore/silcauth.[ch].
3874 * Added `hash' field to the SilcIDListData structure. It is the
3875 hash negotiated in the SKE protocol. Affected file is
3878 * Slight redesigning of the SilcAuthPayload handling routines.
3879 Do not send SilcPKCS but SilcPublicKey as argument.
3881 * Implemented the public key authentication support to the
3882 serverconfig. The public key is loaded from the provided path
3883 and saved as authentication data to void * pointer. Thus,
3884 changed the unsigned char *auth_data to void *auth_data;
3886 * Fixed SHUTDOWN command to send the reply before the server
3887 is shutdown. :) Affected file silcd/command.c.
3889 * Fixed fatal bug in CONNECT command. The hostname was invalid
3890 memory and server crashed. Affected file silcd/command.c.
3892 * Fixed fatal bug in CLOSE command. The server_entry became
3893 invalid but was referenced later in the command. Affected file
3896 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Fixed fatal bug in failure packet handling. Server ignored
3899 the failure and thus crashed when it came.
3903 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3906 that the command may be executed only once in (about) 2 seconds.
3907 The old SILC_CF_LAG flag is same but allows command bursts up
3908 to five before limiting.
3910 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3911 server code. Various commands now includes the CF_LAG_STRICT
3912 flag to disallow any kind of miss-use of the command.
3914 * Fixed the silc_buffer_unformat to not to allocate any data
3915 if the length of the data is zero. It used to allocate the
3916 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3918 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Changed the format of AdminConnection configuration section
3921 in the server. Added username of the admin to the format.
3922 Affected files silcd/serverconfig.[ch].
3924 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3925 to return admin configuration data by host, username and/or
3928 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Implemented WHOWAS command to the server. Added the functions:
3932 silc_server_command_whowas_parse,
3933 silc_server_command_whowas_send_reply,
3934 silc_server_command_whowas_from_client and
3935 silc_server_command_whowas_from_server
3937 * Added <Client ID> argument to the WHOWAS command reply. Updated
3938 the protocol specs accordingly.
3940 * Implemented WHOWAS command and command_reply to the client
3943 Implemented the WHOWAS printing on the user interface.
3945 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Added new argument to the WHOWAS command reply, the real name.
3948 It is an optional argument. Updated the protocol specs.
3950 * Added SilcIDCacheDestructor callback that is registered when
3951 the SilcIDCache is allocated. The callback is called when
3952 an cache entry in the ID Cache expires, or is purged from the
3953 cache. Added into lib/silccore/idcache.[ch].
3955 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3956 to destruct the client entries when the cache entry expires.
3957 Other ID Cache's in server and in the client library ignores
3960 * If the ID Cache entry's `expire' field is zero then the entry
3961 never expires. Added boolean `expire' argument to the
3962 silc_idcache_add function in the lib/silccore/idcache.[ch].
3963 If it is TRUE the default expiry value is used.
3965 * Added silc_server_free_client_data_timeout that is registered
3966 when client disconnects. By default for 5 minutes we preserve
3967 the client entry for history - for WHOWAS command.
3969 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added support to the server to enforce that commands are not
3972 executed more than once in 2 seconds. If server receives
3973 commands from client more frequently, timeout is registered
3974 to process the commands. Affected file silcd/command.c.
3975 Added new function silc_server_command_process_timeout.
3977 * Changed NICK_NOTIFY handling in client library to check that
3978 if the client's nickname was changed, so there is no need to
3979 resolve anything from the server.
3981 * Removed error printing from the WHOIS and IDENTIFY commands.
3982 If error occurs then it is ignored silently in the client library.
3983 The application, however, may map the received error to
3984 human readable error string. The application currently maps
3985 the NO_SUCH_NICKNAME error to string.
3987 * Made the command status message public to the application. Moved
3988 them from lib/silcclient/command_reply.c to
3989 lib/silcclient/command_reply.h. The application can map the
3990 received command status to the string with the
3991 silc_client_command_status_message function.
3993 * Added check to the server to check that client's ID is same
3994 as the Source ID in the packet the client sent. They must
3997 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Added dist-bzip hook to the Makefile.am to make bzip2
4000 compressed distributions.
4002 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Server now enforces the maximum length for the nickname and
4005 the channel as protocol specification dictates. 128 bytes for
4006 nickname and 256 bytes for channel name.
4008 * Moved the WHOIS printing to the application. The client libary
4009 does not print out the WHOIS information anymore, the application
4010 must do it. Renamed silc_client_command_reply_whois_print to
4011 the silc_client_command_reply_whois_save.
4013 The client's idle time is also sent to the application now, and
4014 the idle is shown on screen.
4016 * Added silc_client_command_reply_identify_save to save the
4017 received IDENTIFY entries.
4019 * Do not check for channel private keys in message sending and
4020 reception if the channel does not have the PRIVKEY mode set.
4021 Affected file lib/silclient/client_channel.c.
4023 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4026 just surfaced after chaning the JOIN procedure.
4028 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Added silc_client_get_clients_by_list to get client entries
4031 from Client ID list, that is returned for example by JOIN
4032 and USERS command replies. The application should use this
4033 function for example when JOIN command reply is received to
4034 resolve the clients already on the channel (library does not
4035 do that anymore as USERS command reply is not used in the JOIN
4036 procedure anymore). Affected files lib/silcclient/silcapi.h and
4037 lib/silcclient/idlist.c.
4039 * JOIN command reply and USERS command reply returns now SilcBuffer
4040 pointers instead of unsigned char pointers when returning
4041 the client list and mode list.
4043 * Added <Client ID> argument to the JOIN command reply, mainly
4044 for the server to identify for which client the command was
4045 originally sent. Updated protocol specs accordingly.
4047 * Added SilcDlist private_key pointer to the SilcChannelEntry
4048 in the client to support the channel private keys. Affected
4049 file is lib/silcclient/idlist.h.
4051 * Added SilcChannelPrivateKey argument to the function
4052 silc_client_send_channel_message so that application can choose
4053 to use specific private ke if it wants to. If it is not provided,
4054 the normal channel key is used, unless private keys are set.
4055 In this case the first (key that was added first) is used
4056 as the encryption key.
4058 * Implemented the support for channel private key handling.
4059 Implemented the following functions:
4061 silc_client_add_channel_private_key,
4062 silc_client_del_channel_private_keys,
4063 silc_client_del_channel_private_key,
4064 silc_client_list_channel_private_keys and
4065 silc_client_free_channel_private_keys
4067 Affected file lib/silcclient/client_channel.c.
4069 * Added the support for the private keys in the channel message
4070 sending and encryption and in the message reception and
4071 decryption. Affected funtions are
4072 silc_client_send_channel_message and silc_client_channel_message.
4074 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Added SKE's key verify callback to the client library's
4077 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4079 * Removed the statement that server (or router) must send USERS
4080 command reply when joining to the channel so that the client
4081 knows who are on the channel. Instead, the client list and
4082 client's mode list is now sent in the JOIN command reply to the
4083 client who joined channel. This is better solution.
4085 * Added function silc_server_get_users_on_channel and function
4086 silc_server_save_users_on_channel to the silcd/server.[ch].
4088 * Removed function silc_server_command_send_users from the
4091 * Do not show topic on the client library anymore. The topic is
4092 sent in the command reply notify to the application and the
4093 application must show the topic now.
4095 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Added client searching by nickname hash into the IDENTIFY and
4098 WHOIS commands in the server as they were clearly missing from
4099 them. Affected file is silcd/command.c.
4101 * Fixed a bug in private message receiving in the client library.
4102 The remote ID was freed and it wasn't supposed, now it is
4105 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Minor fix to the channel payload; allocate the data area, as it
4108 needs to be of specific length.
4110 * If the key agreement port is zero then the operating
4111 system will define the bound port. Affected files are
4112 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4114 * Added new function silc_channel_payload_decrypt into the file
4115 lib/silccore/silcchannel.[ch].
4117 * Moved the channel message etc, check from silc_packet_decrypt
4118 to applications. The library calls now a generic
4119 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4120 when the packet is either normal or special. This was done to
4121 allow more wide range of checking that was not allowed when
4122 the code was in library. Now applications can do virtually any
4123 checks to the packet and return to the library the decision how
4124 the packet should be processed. Affected files are
4125 lib/silccore/silcpacket.[ch].
4127 Added silc_server_packet_decrypt_check to the server and
4128 silc_client_packet_decrypt_check to the client library.
4130 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4131 to send with specified source and destination information.
4133 * Channel message delivery between routers was broken after the
4134 channel key distribution was fixed earlier. The channel key
4135 was used be to distributed to other routers as well which is not
4136 allowed by the protocol. Now this is fixed and channel keys
4137 really are cell specific and the channel message delivery between
4138 routers comply with the protocol specification.
4140 * Fixed various commands in server to check also the global list
4141 for the channel entry and not just the local list. The affected
4142 file silcd/command.c.
4144 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Added assert()s to buffer formatting and unformatting routines
4147 to assert (if --enable-debug) when error occurs. Affected
4148 file: lib/silcutil/silcbuffmt.c.
4150 * Changed to auto-reconnect to check whether the remote host is
4151 router and register the re-connect timeout if it is. It used
4152 to check that whether we are normal server, but router must do
4153 auto-reconnect with another router as well. Affected file
4156 * Removed the [<key len>] option from CMODE command as the cipher
4157 name decides the key length, nowadays. See the defined ciphers
4158 from the protocol specification.
4160 * Added [<hmac>] option to the CMODE command to define the HMAC
4161 for the channel. Added SILC_CMODE_HMAC channel mode.
4163 * Added [<hmac>] option for the JOIN command so that user can
4164 select which HMAC is used to compute the MACs of the channel
4167 * Added Hmac field to the Channel Message Payload. The integrity
4168 of plaintext channel messages are now protected by computing
4169 MAC of the message and attaching the MAC to the payload. The
4170 MAC is encrypted. Now, it is clear that this causes some
4171 overhead to the size of the packet but rationale for this is that
4172 now the receiver can verify whether the channel message decrypted
4173 correctly and also when private keys are set for the channel the
4174 receiver can decrypt the packet with several keys and check from
4175 the MAC which key decrypted the message correctly.
4177 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4178 lib/silccrypt/silccipher.[ch].
4180 * Added silc_hash_len to return the digest length into the
4181 lib/silcrypt/silchash.[ch].
4183 * Rewrote parts of Silc Channel Payload interface in the
4184 lib/silccore/silcchannel.[ch]. The encode function now also
4185 encrypts the packet and parse function decrypts it.
4187 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Fixed a minor formatting bug in the SKE's key material processing.
4190 It actually might have processed the keys wrong way resulting
4193 * Redefined the mandatory HMAC algorithms and added new algorithms.
4194 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4195 and hmac-md5 truncated to 96 bits. The mandatory is now
4196 hmac-sha1-96. Rest are optional (including the one that used
4197 to be mandatory). Rationale for this is that the truncated HMAC
4198 length is sufficient from security point of view and can actually
4199 make the attack against the HMAC harder. Also, the truncated
4200 HMAC causes less overhead to the packets. See the RFC2104 for
4203 * Added new [hmac] configuration section. The SKE used to use
4204 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4205 is of course wrong. The official names that must be proposed in
4206 the SKE are the ones defined in the protocol specification
4207 (hmac-sha1-96 for example). The user can configure any hmac
4208 using any hash function configured in the [hash] section. At
4209 least, the mandatory must be configured.
4211 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4213 * Added HMAC list to the SKE proposal list. It has now both
4214 hash algorithm list and HMAC list. This makes the protocol
4215 incompatible with previous versions. The SKE now seems to work
4216 the way it is supposed to work, for the first time actually.
4218 * Defined plain Hash algorithms to the protocol specification.
4221 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Implemented support for key agreement packets into the server.
4224 Added functions silc_server_key_agreement and
4225 silc_server_send_key_agreement. Other than these functions,
4226 server has nothing to do with this packet.
4228 * Added support for private message key packets into the server.
4229 Added functions silc_server_private_message_key and
4230 silc_server_send_private_message_key.
4234 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4235 called in the protocol's final callback instead in the END
4236 protocol state. This makes a little more sense and in the same
4237 time in client we can use the same protocol routines for normal
4238 key exchange and to key agreement packet handling as well.
4240 * Added to both client's and server's KE protocol context the
4241 SilcSKEKeyMaterial pointer to save the key material. We will
4242 bring the key material to the protocol's final callback by doing
4243 this. The final callback must free the key material.
4245 * Added SKE's packet_send callback into client's KE protocol
4246 context so that the caller can choose what packet sending function
4247 is used. This way we can use different packet sending when
4248 doing normal SKE when doing key agreement packet handling (in
4249 the key agreement packet handling we do not want to encrypt
4252 * Implemented the responder side of the key agreement routines
4253 in the client. The client can now bind to specified port and
4254 accept incoming key negotiation. The key material is passed
4255 to the application after the protocol is over.
4257 * Implemented the processing of incoming Key Agreement packet
4258 in the client. Added function silc_client_key_agreement to
4261 * Implemented the intiator side of the key agreement routines
4262 in the client. The client can now initiate key agreement with
4263 another remote client. The key material is passed to the
4264 application after the protocol is over.
4266 * Created client_keyagr.c to include all the key agreement
4269 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4270 SILC_TASK_CALLBACK except that it is not static.
4272 * Created client_notify.c and moved the Notify packet handling
4273 from the client.[ch] into that file.
4275 * Created client_prvmsg.c and moved all private message and
4276 private message key routines from the client.[ch] into that file.
4278 * Create client_channel.c and moved all channel message and
4279 channel private key routines from the client.[ch] into that file.
4281 * Changed silc_client_get_client_by_id_resolve to resolve with
4282 WHOIS command instead of IDENTIFY command, in the file
4283 lib/silclient/idlist.c.
4285 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Implemented the SKE's responder side to the Client library.
4289 * When FAILURE is received to the protocol do not trust it
4290 blindly. Register a timeout to wait whether the remote closes
4291 the connection as it should do it, only after that process the
4292 actual failure. This was changed to both client and server.
4294 * Added client_internal.h to include some of the structures
4295 there instead of client.h in lib/silcclient/.
4297 * Added function silc_task_unregister_by_callback to unregister
4298 timeouts by the callback function.
4300 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Some "Incomplete WHOIS info" errors has been appearing on the
4303 log files. Took away the entry->userinfo check from WHOIS
4304 reply sending. The entry->userinfo is now " " if client did not
4305 provide one. I thought this was fixed earlier but something
4306 is wrong still. Let's see if the error still appears.
4308 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Fixed a minor bug in the login when the channel key is
4311 re-generated in the server. It used to generate the key in
4312 wrong order and thus caused problems in the channel traffic.
4314 * Fixed a minor bug in channel key distsribution after
4315 KICK command. The key was not sent to the router even though
4318 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * Added silc_ske_process_key_material_data as generic routine
4321 to process any key material as the SILC protocol dictates. The
4322 function is used by the actual SKE library but can be used by
4323 applications as well. This relates to the private message keys
4324 and the channel private keys since they must be processed the
4325 same way the normal SILC session keys. The protocol dictates
4326 this. Affected files: lib/silcske/silcske.[ch].
4328 Added also silc_ske_free_key_material to free the
4329 SilcSKEKeyMaterial structure.
4331 * Defined silc_cipher_set_key function to set the key for
4332 cipher without using the object's method function. The affected
4333 files: lib/silccrypt/silccipher.[ch].
4335 * Implemented silc silc_client_add_private_message_key,
4336 silc_client_add_private_message_key_ske,
4337 silc_client_del_private_message_key,
4338 silc_client_list_private_message_keys and
4339 silc_client_free_private_message_keys functions in the
4342 Added functions silc_client_send_private_message_key to send
4343 the Private Message Key payload and silc_client_private_message_key
4344 to handle incoming Private Message Key payload.
4346 * Added Cipher field to the Private Message Key payload to set
4347 the cipher to be used. If ignored, the default cipher defined
4348 in the SILC protocol (aes-256-cbc) is used.
4350 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4352 * Removed lib/silcclient/ops.h file.
4354 Redefined parts of the SILC Client Library API. Created new
4355 file silcapi.h that deprecates the ops.h file and defines the
4356 published Client Library API. Defined also private message key
4357 API and channel private key API into the file.
4359 This is the file that the application must include from the
4360 SILC Client Library. Other files need not be included by
4361 the application anymore.
4363 * Added new key_agreement client operation callback and also
4364 defined the Key Agreement library API for the application.
4366 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4369 is used by clients to request key negotiation between another
4370 client in the SILC network. If the negotiation is started it
4371 is performed using the SKE protocol. The result of the
4372 negotiation, the secret key material, can be used for example
4373 as private message key.
4375 Implemented the Key Agreement payload into the files
4376 lib/silccore/silauth.[ch].
4378 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Redefined ciphers for the SILC protocol. Added some new ciphers
4381 and defined the key lengths for the algorithms. Changed the
4382 code accordingly. The default key length is now 256 bits.
4384 * Fixed SKE key distribution function silc_ske_process_key_material
4385 when the key length is more than 128 bits. The default key
4386 length in SILC is now 256 bits.
4388 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4389 to indicate unsupported algorithm.
4391 * Renamed rijndael.c to aes.c and all functions as well.
4393 * Fixed a long standing channel key setting bug in client library.
4394 Weird that it has never surfaced before.
4396 * Fixed bug in channel deletion. If the entire channel is removed
4397 then it must also delete the references of the channel entry
4398 from the client's channel list as the client's channel entry and
4399 the channel's client entry share same memory.
4401 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Implemented CONNECT and SHUTDOWN commands in the client.
4405 * Implemented CLOSE command to the client.
4407 * Added the function silc_idlist_find_server_by_name into the
4408 files silcd/idlist.[ch].
4410 Added the function silc_idlist_find_server_by_conn into the
4411 files silcd/idlist.[ch].
4413 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * DIE command was renamed to SHUTDOWN. Updated the both code
4418 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4419 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4421 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4424 * Added function silc_server_create_connection function to create
4425 connection to remote router. My server implementation actually
4426 does not allow router to connect to normal server (it expects
4427 that normal server always initiates the connection to the router)
4428 so the CONNECT command is only good for connecting to another
4431 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4434 or some other client was kicked from the channel.
4436 Implemented the handling of the notify type to both client
4439 Implemented silc_server_send_notify_kicked to send the KICKED
4440 notify. It is used to send it to the server's primary router.
4442 * Implemented the KICK command into server and client.
4444 * Added `query' argument to the silc_idlist_get_client function
4445 to indicate whether to query the client from server or not if
4448 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4449 to indicate that the client is not channel founder.
4453 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * Removed the rng context from SilcPacketContext structure and
4456 changed that the packet routine uses the Global RNG API.
4458 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added support for quit message that client can "leave" on the
4461 channel when it quits the SILC. It is ditributed inside the
4462 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4464 Added silc_server_free_client_data that will take the
4465 signoff message as argument.
4467 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4469 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Updated parts of the protocol specification to keep it up
4474 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4477 payloads in one packet.
4479 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4480 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4481 use now the new List flag.
4483 * Also deprecated the following packet types: REPLACE_ID,
4484 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4486 * Added list support for Notify packet in server.
4488 * Added silc_server_send_notify_channel_change to send the
4489 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4490 the silc_server_send_replace_id.
4492 * Added silc_server_send_notify_nick_change to send the
4493 NICK_CHANGE notify type. Deprecates the function
4494 silc_server_send_replace_id.
4496 * Added silc_server_send_notify_join to send the JOIN notify type.
4497 Deprecates the function silc_server_send_new_channel_user.
4499 * Added silc_server_send_notify_leave to send LEAVE notify type.
4500 Deprecates the function silc_server_send_remove_channel_user.
4502 * Added silc_server_send_notify_cmode and
4503 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4504 types. Deprecates the silc_server_send_set_mode function.
4506 * Added SERVER_SIGNOFF notify type to indicate that server has
4507 quit. This means that all clients on the channel from that
4508 server will drop. This can be also used when netsplit happens.
4510 Deprecated REMOVE_ID packet type since it is not needed anymore
4513 Added silc_server_send_notify_server_signoff to send the
4514 SERVER_SIGNOFF notify type. Deprecates the function
4515 silc_server_send_remove_id.
4517 Added also silc_server_send_notify_signoff to send the
4518 SIGNOFF notify type.
4520 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4521 SILC protocol from this day on. Changed the protocol
4522 specification as well.
4524 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4525 notify type. It is used between routers to notify about
4526 topic changes on a channel.
4528 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4531 * Partly updated the protocol specification to comply with the
4532 changes now made. It is still though a bit outdated.
4534 * The JOIN notify type now takes one extra argument <Channel ID>.
4535 The packet used to be destined to the channel but now the
4536 JOIN type may be sent as list thus it is impossible to
4537 destine it to any specific channel. By adding this argument
4538 it is again possible.
4540 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added CREDITS file. The CHANGES and CREDITS file will appear
4543 in the distribution as well.
4545 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4548 types in the server's silcd/packet_receive.c.
4550 * Implemented CMODE and CUMODE to work in router environment.
4552 * Fixed minor encoding and decoding buglet from the
4553 lib/silccore/silcmode.c.
4555 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4558 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4560 * Changed all SilcConfigServer* and silc_config_server* to
4561 SilcServerConfig* and silc_server_config*, respectively.
4564 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Associated the ID (client or server ID) to the Authentication
4567 Payload to avoid any possibility of forging. Updated the
4568 protocol specification and the code accordingly.
4570 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * The RSA key length is now save to the RsaKey context in the
4573 key generation process in lib/silccrypt/rsa.c. The key length
4574 is now used to figure out the maximum size of the block allowed
4575 to be encrypted/signed.
4577 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4578 is equivalent to the silc_mp_mp2bin but does not allocate any
4581 * Changed silc_mp_mp2bin API to take length argument. If it is
4582 non-zero then the buffer is allocated that large. If zero, then
4583 the size is approximated using silc_mp_sizeinbase, which however
4586 * Created Global RNG API which is global RNG that application can
4587 initialize. After initializing, any routine anywhere in the
4588 code (including library) can use RNG without allocating a new
4589 RNG object. This was done to allow this sort of use of the
4590 RNG in code that has no chance to allocate RNG object. All
4591 applications currently allocate this and many routines in the
4592 library use this. Affected file lib/silccrypt/silcrng.[ch].
4594 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4595 it to use the Global RNG API.
4597 * Defined Authentication Payload into protocol specification that
4598 is used during SILC session to authenticate entities. It is
4599 used for example by client to authenticate itself to the server
4600 to obtain server operator privileges.
4602 Implemented this payload into the lib/silccore/silcauth.[ch].
4603 Implemented also routines for public key based authentication
4604 as the new protocol specification dictates.
4606 Moved definitions of different authentication methods from
4607 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4609 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4610 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4611 silc_pkcs_verify_with_hash functions into the file
4612 lib/silccrypt/silcpkcs.[ch].
4614 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * The client entry's userinfo pointer must be always valid.
4617 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4618 will fail since it requires the userinfo. Now, the userinfo
4619 is allocated as "" if actual userinfo does not exist. Actually,
4620 it must exist and it is totally Ok to drop client connections
4621 that does not announce the userinfo. However, we will make
4622 this workaround for now.
4624 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4625 to return the remote port by socket.
4627 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4630 SILC_SERVER_PENDING_EXEC and added an new macro
4631 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4632 data or when error occurs while processing the pending command.
4634 Added new argument `destructor' into silc_server_command_pending
4635 and to the SilcServerCommandPending object. This destructor is
4636 now called after calling the pending callback or if error occurs
4637 immediately. If error occurs the actual pending callback won't
4638 be called at all - only the destructor. The destructor may be
4639 NULL if destructor is not needed.
4641 All this applies for client library code as well. Similar
4642 changes were made there as well for the pending commands.
4644 In the client, the application must now allocate the
4645 SilcClientCommandContext with the silc_client_command_alloc
4648 * Added reference counter to the SilcServerCommandContext. Added
4649 function silc_server_command_alloc and silc_server_command_dup
4652 Same type of functions added to the client library for the same
4655 * Removed the cmd_ident from IDListData away since it is now
4656 global for all connections. It is the command identifier used
4657 in command sending and with pending commands. The affected file
4660 * Added reference counter to the SilcSocketConnection objecet to
4661 indicate the usage count of the object. The object won't be
4662 freed untill the reference counter hits zero. Currently only
4663 server uses this, and client ignores it. The client must be
4664 set to use this too later. The affected files are
4665 lib/silccore/silcsockconn.[ch]. Added also the function
4666 silc_socket_dup to increase the reference counter.
4668 This was mainly added because it is possible that the socket
4669 is removed underneath of pending command or other async
4670 operation. Now it won't be free'd and proper DISCONNECTING
4671 flags, etc. can be set to avoid sending data to connection that
4672 is not valid anymore.
4674 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4675 the connection. After that it sets SILC_SET_DISCONNECTED.
4676 It is, however, possible that the socket data is not still freed.
4677 The silc_server_packet_process now checks that data is not
4678 read or written to connection that is DISCONNECTED. The socket
4679 get's freed when the reference counter hits zero.
4681 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Changed the client operation API: channel_message operation's
4684 `sender' is now the client entry of the sender, not the nickname
4685 and the `channel' is the channel entry, not the channel name.
4687 In the private_message operation the `sender' is now also the
4688 client entry of the sender not the nickname.
4690 Affected file is lib/silcclient/ops.h and all applications
4691 using the client operations.
4693 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4695 * Moved the calling of ops->connect() from connect_to_server_final
4696 into receive_new_id functin since that is the point when the
4697 client is actually allowed to send traffic to network. The
4698 affected file is lib/silcclient/client.c.
4700 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4703 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4704 (if needs broadcasting) instead of broadcasting the packets one
4705 by one which would make a burst in the network traffic.
4707 * Added `broadcast' argument to the functions in silcd/server.[ch]
4708 silc_server_create_new_channel[_with_id] to indicate whether
4709 to send New Channel packet to primary router.
4711 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Added new function into the silcd/server.[ch] files:
4714 silc_server_create_new_channel_with_id to create new channel with
4715 already existing Channel ID.
4717 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4718 lib/silccore/silcpacket.h. This packet is used t send list of
4719 Set Mode payloads inside one packet. Server uses this to set
4720 the modes for the channels and clients on those channels, that it
4721 announced to the router when it connected to it. The protocol
4722 specification has been updated accordingly.
4724 * The silc_server_new_channel did not handle the packet coming
4725 from normal server as it normally does not send that. However,
4726 when it announces its channels it does send it. Implemented
4727 the support for that.
4729 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4730 into the file lib/silccore/id.h.
4732 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Fixed memory leaks in the functions silc_idlist_del_client,
4735 silc_idlist_del_channel and silc_idlist_del_server in the file
4736 silcd/idlist.c. All of those leaked like a sieve.
4738 * Fixed some small memory leaks in the client's function
4739 silc_client_notify_by_server.
4741 * Added functions into silcd/server.c: silc_server_announce_clients,
4742 silc_server_announce_channels and silc_server_announce_server.
4743 These functions are used by normal and router server to announce
4744 to its primary router about clients, channels and servers (when
4745 router) that we own. This is done after we've connected to the
4748 These functions effectively implements the following packet types:
4749 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4750 and SILC_PACKET_NEW_ID_LIST.
4752 * Added new functions into the silcd/packet_receive.[ch]:
4753 silc_server_new_id_list, silc_server_new_channel_list and
4754 silc_server_new_channel_user_list to handle the incoming
4755 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4757 * Added support of changing Channel ID in the function
4758 silc_server_replace_id. If the server that announces a channel
4759 to the router already exists in the router (with same name but
4760 with different Channel ID), router is responsible to send
4761 Replace ID packet to the server and force the server to change
4762 the Channel ID to the one router has.
4764 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4765 client that the Channel ID has been changed by the router. The
4766 normal server sends this to the client. Client must start using
4767 the new Channel ID as the channel's ID.
4769 Implemented handling of this new type into lib/silcclient/client.c
4770 into the function silc_client_notify_by_server.
4772 * Added new function silc_idlist_replace_channel_id into the files
4773 silcd/idlist.[ch] to replace the Channel ID.
4775 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Call silc_server_command_identify_check always when processing
4778 the IDENTIFY command in silcd/command.c
4780 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4783 send keepalive packets. The packet can be sent by clients,
4784 servers and routers.
4786 Added function silc_socket_set_heartbeat into the file
4787 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4788 If not set, the heartbeat is not performed. The actual
4789 heartbeat is implemented in the low level socket connection
4790 library. However, application is responsible of actually
4793 Added silc_server_send_heartbeat to send the actual heartbeat
4794 packet into silcd/packet_send.[ch]. Server now performs
4795 keepalive with all connections.
4797 * Added silc_task_get_first function into lib/silcutil/silctask.c
4798 to return the timeout task with shortest timeout. There was a bug
4799 in task unregistration that caused problems. TODO has been
4800 updated to include that task system must be rewritten.
4802 * The client library will now resolve the client information when
4803 receiving JOIN notify from server for client that we know but
4804 have incomplete information.
4806 * Rewrote parts of silc_server_remove_from_channels and
4807 silc_server_remove_from_one_channel as they did not remove the
4808 channel in some circumstances even though they should've.
4810 * Encryption problem encountered in server:
4812 The LEAVE command used to send the Channel Key packet to the
4813 router immediately after generating it. However, the code
4814 had earlier sent Remove Channel user packet but not immediately,
4815 ie. it was put to queue. The order of packets in the router
4816 was that Channel Key packet was first and Remove Channel User
4817 packet was second, even though they were encrypted in the
4818 reverse order. For this reason, MAC check failed. Now, this
4819 is fixed by not sending the Channel Key packet immediately but
4820 putting it to queue. However, this is more fundamental problem:
4821 packets that are in queue should actually not be encrypted
4822 because packets that are sent immediately gets encrypted
4823 actually with wrong IV (and thus MAC check fails). So, packets
4824 that are in queue should be encrypted when they are sent to
4825 the wire and not when they put to the queue.
4827 However, the problem is that the current system has not been
4828 designed to work that way. Instead, the packet is encrypted
4829 as soon as possible and left to the queue. The queue is then
4830 just purged into wire. There won't be any fixes for this
4831 any time soon. So, the current semantic for packet sending
4834 o If you send packet to remote host and do not force the send
4835 (the packet will be in queue) then all subsequent packets to the
4836 same remote host must also be put to the queue. Only after the
4837 queue has been purged is it safe again to force the packet
4840 o If you send all packets immediately then it safe to send
4841 any of subsequent packets through the queue, however, after
4842 the first packet is put to queue then any subsequent packets
4843 must also be put to the queue.
4845 Follow these rules and everything works fine.
4847 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Added new function silc_server_remove_clients_by_server to
4850 remove all client entries from ID list when the server connection
4851 is lost. In this case it is also important to invalidate all
4852 client entires as they hold the invalid server entry. This
4853 fixes fatal bug when server has lost connection and will reconnect
4856 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Made some sanity checks to silc_server_daemonise like to check
4859 whether the requested user and group actually exists.
4861 * Added sanity check to SKE's silc_ske_responder_finish to check
4862 that the public and private key actually is valid.
4864 * Invalidate the client's nickname when receiving Replace ID
4865 packet and the Client ID is being replaced. This means that the
4866 server will query the nickname if someone needs it (client)
4869 * Sort the ID Cache in client library when the ID Cache data
4870 has changed (needs sorting).
4872 * Do not allow for SILC client to create several connections to
4873 several servers. The client does not support windows right now
4874 and generating multiple connections causes weird behaviour.
4876 Irssi-silc client does support windows and can handle several
4877 connections without problems, see: www.irssi.org and SILC plugin.
4879 * Fixed some places where client was added to the IDList. The
4880 rule of thumb is following (in order to get everything right):
4881 If the client is directly connected local client then the
4882 `connection' argument must be set and `router' argument must be
4883 NULL to silc_idlist_add_client function. If the client is not
4884 directly connected client then the `router' argument must
4885 bet set and the `connection' argument must be NULL to the
4886 silc_idlist_add_client function.
4888 * The funtion silc_server_packet_send_local_channel actually did
4889 not check whether the client was locally connected or not. It
4890 does that now. Fixed a bug related to LEAVE command.
4892 * Fixed Remove Channel User payload parsing bug in server's
4893 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4895 * The server's silc_server_save_channel_key now checks also the
4896 global ID list for the channel as it might not be in the local
4897 list. Fixed a bug related to LEAVE command.
4899 * Is this the end of the [<unknown>] buglet that has been lurking
4900 around for a long time? A little for loop fix in server's
4901 silc_server_command_whois_parse that is used by both IDENTIFY
4902 and WHOIS command. At least, this was a clear bug and a cause
4903 of one type of [<unknown>] buglet.
4905 * WHOIS and IDENTIFY commands call the function
4906 silc_server_command_[whois/identify]_check function even if
4907 we are not router server.
4909 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Added --with-gmp configuration option. If set the GMP
4912 is always compiled in the SILC source tree. If not set then
4913 it is checked whether the system has the GMP3 installed. If
4914 it has then the GMP won't be compiled (the system's headers
4915 and library is used), if it doesn't have it then the GMP is
4916 compiled in the SILC source tree.
4918 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Changed RSA private exponent generation to what PKCS #1
4921 suggests. We try to find the smallest possible d by doing
4922 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4923 not security fix but optimization.
4925 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Added new config entry [Identity] to fork the server and run
4928 it as specific user and group. A patch from Bostik.
4930 * Imported Dotconf configuration library into lib/dotconf.
4931 This will be used to create the SILC configuration files later.
4932 It will appear in the distsribution after this commit.
4934 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * A big code auditing weekend happening. Auditing code for
4937 obvious mistakes, bugs and errors. Also, removing any code
4940 Removed files for being obsolete:
4942 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4943 inline in the file lib/silcutil/silcbuffer.h)
4945 o lib/silcutil/silcbufutil.c (the header has inline versions)
4947 Changed code to fix possible error conditions:
4949 o The buffer formatting routines now check that the destination
4950 buffer really has enough space to add the data. This applies for
4951 both buffer formatting and unformatting
4952 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4953 unformatting was changed to accomodate following rules:
4954 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4955 sent to the function while XXX_*STRING will not allocate or copy
4956 the data into the buffer. Instead it sets the pointer from the
4957 buffer into the pointer sent as argument (XXX_*STRING used to
4958 require that the pointer must be allocated already). This change
4959 makes this whole thing a bit more consistent and more optimized
4960 (note that the data returned in the unformatting with XXX_*STRING
4961 must not be freed now). The routines return now -1 on error.
4963 o Tried to find all code that use buffer_format and buffer_unformat
4964 and added return value checking to prevent formatting and
4965 especially unformatting errors and possible subsequent fatal
4968 o Changed ske->x and ske->KEY to mallocated pointers in
4969 lib/silcske/silcske.h. Fixed possible data and memory leak.
4971 o Added return value checking to all *_parse* functions. Fixed
4972 many memory leaks as well.
4974 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4975 so that buffer overflows would not happen. All code now also
4976 checks the return value as it can fail.
4978 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added reconnection support to server if the normal server looses
4981 its connection to the router (for example if router is rebooted).
4982 The server performs normal reconnection strategy implemented
4983 to the server. Affected file silcd/server.c.
4985 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Added new packet type SILC_PACKET_SET_MODE that is used to
4988 distribute the information about changed modes (for clients,
4989 channels and clients channel modes) to all routers in the
4990 network. Updated the protocol specification accordingly.
4992 Added functions into silcd/packet_send.c and
4993 silcd/packet_receive.c: silc_server_send_set_mode,
4994 silc_server_set_mode.
4996 Added new files silcmode.[ch] into lib/silccore that implements
4997 the encoding and decoding of Set Mode Payload. Added new type
4998 SilcSetModePayload. Moved the definitions of different modes
4999 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5001 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Oops, a little mistake in server's connection authentication
5004 protocol. The protocol is not ended with FAILURE but with
5005 SUCCESS if the authentication is Ok. :) Affected file is
5008 * Implemented NICK_CHANGE notify handling in server in the file
5009 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5010 the local clients on the channel. After the changing nickname
5011 in router environment snhould work and the [<unknown>] nickname
5012 should appear no more.
5014 The silc_server_replace_id function that receives the Replace ID
5015 payload now sends the NICK_CHANGE notify type also in the file
5016 silcd/packet_receive.c
5018 * Changed WHOIS and IDENTIFY command to support the maximum amount
5019 of arguments defined in protocol specs (3328 arguments). This
5020 fixed a bug that caused problems when there were more than three
5023 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Added extra parameter, command identifier, to the
5026 silc_client_send_command so that explicit command identifier
5029 Changed that ID list routines uses specific command identifier
5030 when sending WHOIS/IDENTIFY requests to the server so that they
5031 can be identified when the reply comes back.
5033 Affected files lib/silcclient/command.[ch],
5034 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5036 * Added `sender' argument to silc_server_packet_send_to_channel
5037 to indicaet the sender who originally sent the packet to us
5038 that we are now re-sending. Ignored if NULL. Affected file
5039 silcd/packet_send.[ch].
5041 * Added some server statistics support in silcd/server_internal.h
5042 SilcServerStatistics structure and around the server code. Also
5043 send some nice statistics information when client is connecting
5046 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Fixed channel ID decoding in server's JOIN command reply in
5049 silcd/command_reply.c
5051 * Fixed braodcasting of replace ID payload to not to send it if
5052 we are standalone server in silcd/packet_receive.c.
5054 * Fixed all channel message sending routines to not to send
5055 packets to clients that has router set, since they are routed
5056 separately in the same function earlier. Affects file
5057 silcd/packet_send.c and all channel packet sending functions.
5059 * In USERS reply, res_argv[i] are not allocated, the table
5060 is allocated. Thus changed that free the table, not its
5063 * In server's whois_check and identify_check if the client is
5064 locally connected do not send any WHOIS commands - they are not
5067 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Fixed some minor bugs in client when sending WHOIS command. The
5070 arguments was in wrong order.
5072 * Removed statis function add_to_channel from server in
5073 silcd/command.c that was previously used with the joining but
5076 * Tested USERS command in router environment successfully with two
5077 routers, two servers and two clients.
5079 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Reorganized the USERS command and command reply in client library
5082 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5083 When the command is given by user we register a pending command
5084 callback that will reprocess the command after the reply has been
5085 received from the server. When reprocessing the packet we then
5086 display the information. Thus, the USERS information is displayed
5087 now in the command callback instead of in the command reply
5088 callback. The processing of the command is same as previously
5089 when server has sent the command reply in the JOINing process.
5091 * Added to USERS command in silcd/command_reply.c to join the client,
5092 we didn't use to know about, to the channel after we've created
5093 a client entry for it. Also, for clienet we did know already still
5094 check whether it is on the channel or not and add it if not.
5096 * Removed silc_server_command_join_notify as the function and its
5099 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Changed the client's pending command handling to the same as the
5102 server's pending command handling. It is also now possible to
5103 execute command reply functions from other command reply
5104 function as the function callbacks for commands and command
5105 replies are one and same. The pending commands are not static
5106 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5107 in client connection context. Thus, pending commands are server
5108 connection specific as it is convenient.
5110 Changed the function silc_client_command_pending and
5111 silc_client_command_pending_del and added new function
5112 silc_client_command_pending_check. Removed the
5113 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5116 * Added cmd_ident, current command identifier, to the client
5117 connection context in lib/silcclient/client.h to keep track on
5118 command identifiers used in command sending. Client's command reply
5119 function handling now supports the mandatory command identifiers.
5121 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5122 funtions in client to fully support pending command callbacks.
5124 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5125 as one of the arguments to the application in the command reply
5128 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5129 before first releasing SILC but came back. Now it is removed again
5130 and should come back nomore. The FORWARDED flag was used only
5131 by the JOINing procedure by forwarding the command packet to router.
5132 Now, the JOINing procedure has been changed to more generic (due
5133 to various router environment issues) and FORWARDED is not needed
5134 anymore for anything. The protocol specification is yet to be
5137 Now, removed silc_server_packet_forward from server and the flag
5138 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5140 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Renamed NAMES command to USERS command. The NAMES was named that
5143 due to historical reasons. Now it is renamed. Also, rewrote
5144 parts of the USERS command. The nickname list is not sent anymore
5145 by the server. Only Client ID and mode lists are sent in the USERS
5146 command. Changed this also to the protocol specification.
5148 The client now resolves the names and stuff after it receives
5149 the USERS list from the server when joining to the channel.
5151 * WHOIS and IDENTIFY commands has been changed to support multiple
5152 Client ID's per command. One can now search for multiple users
5153 in the network by sending only one WHOIS or IDENTIFY command.
5154 Changed the code and the protocol specifications.
5156 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5157 uses silc_server_command_whois_parse to parse the request. */
5159 * If normal server, do not parse the WHOIS and IDENTIFY requests
5160 before sending it to the router. Saves some time.
5162 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Fixed JOIN command on client library. Wrong number of arguments
5165 used to crash the client.
5167 * Added silc_server_channel_has_global function to check whether
5168 channel has global users or not.
5170 * Added silc_server_channel_has_local function to check whether channel
5171 has locally connected clients on the channel.
5173 * The silc_server_remove_from_one_channel now checks whether the
5174 channel has global users or not after given client was removed from
5175 the channel. It also checks whether the channel has local clients
5176 on the channel anymore. If it does not have then the channel entry
5177 is removed as it is not needed anymore.
5179 * The silc_server_notify now checks on JOIN notify whether the joining
5180 client is one of locally connected or global. If it is global then
5181 the channel has now global users on the channel and that is marked
5182 to the channel entry. Also, it now saves the global client to
5183 global list who is joining and JOINs it to the channel. This is
5184 for normal server, that is.
5186 Changed silc_server_send_notify_on_channel,
5187 silc_server_packet_relay_to_channel and
5188 silc_server_packet_send_to_channel check if we are normal server
5189 and client has router set (ie. global client) do not send the
5190 message to that client, as it is already routed to our router.
5192 * Implemented LEAVE notify type handling in silc_server_notify
5195 * Tested LEAVE command in router environment successfully. Tested
5196 with two routers, two servers and two clients.
5200 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5202 * Implemented SIGNOFF notify type handling in silc_server_notify
5205 * silc_server_remove_id now removes the client entry from all channels
5206 it has joined and thusly sends SIGNOFF notify type.
5208 * Rewrote the NAMES list generation in server by removing two excess
5209 loops. The lists are created now inside one loop.
5211 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * silc_server_remove_channel_user checks now also global list
5214 for channel and client.
5216 * silc_server_new_channel_user checks now both local and global
5217 list for channel and client. Fixed a bug in client id decoding.
5218 Used to decode wrong buffer.
5220 * silc_server_channel_message checks now both local and global
5221 list for channel entry.
5223 * Tested channel joining (hence JOIN) in router environment
5224 successfully. Tested with two routers, two servers and two
5227 * Tested channel message sending in router environment successfully.
5229 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Added silc_server_save_channel_key into server.[ch] to save the
5232 received channel key in Channel Key payload processing. It is
5233 also used in JOIN command reply handling.
5235 Equivalent function silc_client_save_channel_key added into
5236 client.[ch] into client library.
5238 * Changed JOIN command reply to send information whether the channel
5239 was created or not (is existing already) and the channel key
5240 payload. Changed protocol specs accordingly.
5242 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5243 the request was sent by ID and not by nickname. Crashed on
5246 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5249 now correctly save the received data.
5251 * silc_server_free_sock_user_data now notifies routers in the
5252 network about entities leaving the network.
5254 At the same time implemented functions silc_server_remove_id
5255 and silc_server_send_remove_id to receive and send REMOVE_ID
5256 packets. The packet is used to notify routers in the network
5257 about leaving entities. The ID removed will become invalid in
5260 * Added function silc_idlist_del_server into server. Removes and
5261 free's server entry from ID list.
5263 * silc_server_private_message function now checks, if we are router,
5264 that the destination ID really is valid ID, naturally.
5266 * In router when NEW_ID packet is received (for new client) the
5267 hash of the Client ID is saved in the ID Cache but the
5268 client->nickname is set to NULL, instead of putting the hash
5271 IDENTIFY command now also checks that client->nickname must be
5272 valid. If it is not if will request the data from the server who
5273 owns the client. Added new function
5274 silc_server_command_identify_check.
5276 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5277 to set the command to already allocated Command Payload.
5279 * Tested private message sending in router environment with two
5280 routers, two servers and two clients. Fixed minor bugs and now
5283 * Fixed segfault from client's NAMES command. Used to crash if
5286 * Forwarded packets must not be routed even if it is not destined
5287 to the receiver. Changed server code comply with this.
5289 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Added `require_reverse_mapping' boolean value to ServerParams
5292 structure. If TRUE (not default) the server will require that
5293 the connecting host has fully qualified domain name.
5295 If the reverse mapping is not required and hostname could not be
5296 found the IP address is used as hostname.
5298 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Implemented version string checking to both client and server.
5301 The check is incomplete currently due to the abnormal version
5302 strings used in development version of SILC.
5304 * Changed all command functions in server to use the new
5307 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Changed char *data to unsigned char *data in ID Cache system to
5310 support binary data as ID Cache data. Changed code to support
5311 binary data in lib/silccore/idcache.c.
5313 * Renamed silc_server_packet_relay_command_reply to
5314 silc_server_command_reply as it is normal packet receiving
5315 function. Rewrote the function to accept command replys for
5316 servers and not only for clients.
5318 * Mark remote router always as registered server if we are connecting
5319 to it. Otherwise, commands sent by the router to us are ignored.
5321 * All ID List find routines now returns the ID Cache Entry pointer
5322 as well if requested.
5324 * WHOIS command works now in router environment, tested with two
5325 routers, two servers and two clients.
5327 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5328 in router environment (as it is almost equivalent to WHOIS) but
5329 hasn't been tested thoroughly. Added new functions:
5331 silc_server_command_identify_parse
5332 silc_server_command_identify_send_reply
5333 silc_server_command_identify_from_client
5334 silc_server_command_identify_from_server
5336 * Disabled route cache adding because adding two different ID's with
5337 same IP replaces the old cache entry thus giving wrong route.
5338 The entry->router->connection is always the fastest route anyway
5339 so route cache may not be needed. Of course, new routes maybe
5340 established after receiving the ID when the entry->router->connection
5341 might not be anymore the most optimal.
5343 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Add route cache for received ID for fast routing.
5347 * Added silc_server_packet_route to route received packet on router
5348 that is not destined to us.
5350 * Renamed silc_server_get_route to silc_server_route_get.
5352 * Added id_string and id_string_len fields into SilcServer to
5353 include encoded ServerID for fast comparing without excess
5354 encoding of the ID's.
5356 * Cleaned up WHOIS command on server side. Added following static
5359 silc_server_command_whois_parse
5360 silc_server_command_whois_check
5361 silc_server_command_whois_send_reply
5362 silc_server_command_whois_from_client
5363 silc_server_command_whois_from_server
5365 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5366 arguments in command replies. All command functions should be
5367 updated to use this macro.
5369 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Minor typo fixes on command reply handling on server.
5373 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Added silc_server_command_add_to_channel internal routine to add
5376 the client to the channel after router has created the channel and
5377 sent command reply to the server.
5379 * Added generic silc_server_send_command to send any command from
5382 * Use static buffer with ID rendering instead of duplicating data.
5384 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Fixed a channel user mode bug when joining to a channel server gave
5387 everybody channel founder rights, oops.
5389 * We mark ourselves as the router of the incoming server connection
5390 if we are router ourselves. This way we can check in some packet
5391 sending functions whether it is locally connected server. For
5392 incoming router connections we put NULL.
5394 * For router sending packets locally means now always sending the
5395 packet cell wide; to local clients and local servers. For normal
5396 server sending packet locally means sending it to only local
5399 * Fixed the JOIN command to really work in router environment. If the
5400 channel is created it is always created by the router. Router is
5401 also responsible of making the initial joining to the channel,
5402 sending JOIN notify to the sending server and distributing
5403 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5404 does not exist server doesn't do anything else but forward the
5405 command to the router which performs everything.
5407 * Added silc_server_send_channel_key function to send the Channel Key
5410 * Added silc_server_create_channel_key to create new channel key. The
5411 channel key is now re-generated everytime someone joins or leaves
5412 a channel, as protocol dictates. Note: channel->key_len is the
5415 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5418 packet_receive.[ch] to separate packet sending and receiving
5419 routines. The server.[ch] now includes everything else including
5420 actual packet processing (writing and reading data) and other
5423 Renamed silc_server_private_message_send_internal to
5424 silc_server_send_private_message. The routine is still though
5425 used only to relay private messages as server does not send
5426 private messages itself.
5428 Renamed silc_server_new_channel to silc_server_create_new_channel
5429 and added new function sicl_server_new_channel that handles the
5430 incoming New Channel packet. Added also new sending function
5431 silc_server_send_new_channel to send New Channel Payload.
5433 * Added new function silc_server_notify to process incoming notify
5434 packet to the server/router. Server may then relay the notify
5435 to clients if needed.
5437 * Added new function silc_server_new_channel_user to process incoming
5438 New Channel User packet. Router will redistribute the packet and
5439 send JOIN notify to its local clients and locally connected servers
5440 if needed. Normal server will send JOIN notify to its local client
5441 on same channel when received this packet. Added also corresponding
5442 sending function silc_server_send_new_channel_user to sent the
5445 * Added boolean route argument to send_notif_to_channel and
5446 packet_send_to_channel functions to attempt to route the packet
5447 if it is TRUE and send only locally if it is FALSE.
5449 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * silc_server_replace_id now broadcasts the received replace ID
5452 packet if it is not broadcast packet already. The router must
5453 broadcast to inform other routers about changed ID.
5455 * Added backpointer to server's router into SilcServer context in
5456 silcd/server_internal.h.
5458 * Fixed silc_server_packet_broadcast to send correct broadcast
5461 * The channel key is now distributed to the local client as soon
5462 as it is received from the router (in router environment) so that
5463 no other packet may be sent for the channel until client has
5466 * silc_server_remove_channel_user now broadcasts the received
5467 Remove Channel User packet if it is not broadcast packet already.
5468 The router must broadcast to inform other routers about removed
5471 * Added users field into SilcPacketContext that is a reference count
5472 of the context. One can increase the reference count by calling
5473 silc_packet_context_dup which is now changed to just increase the
5474 reference count instead of duplicating the data. The reference
5475 count is decresed by calling silc_packet_context_free that will
5476 free the data after the reference count hits zero.
5478 For now on the packet context and everything allocated into it
5479 (including the raw packet from network) must be freed by calling
5480 the new silc_packet_context_free function. Added also new function
5481 silc_packet_context_alloc that must be used now to allocate the
5482 context. This also means that if a routine is asynchronous from
5483 silc_[client/server]_packet_parse_type the packet context must
5484 be duplicated by calling silc_packet_context_dup. Otherwise it
5485 gets free'd after silc_[client/server]_packet_parse_type returns.
5486 Also, one must remember that if packet is duplicated then its
5487 reference count must be decresed by calling the free function as
5488 many times as it was duplicated.
5490 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5491 from both client and server.
5493 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Made joining to a channel working in router environment.
5497 * Cleaned up JOIN command on server side and create function
5498 silc_server_command_join_channel internal routine to make the
5501 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Changed silc_command_pending list to SilcDList. Also, added
5504 `ident' field to SilcServerCommandPending structure to identify
5505 the reply and to call correct callback.
5507 Added silc_server_command_pending_check function to replace the
5508 corresnponding macro. The silc_command_pending list is not
5511 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5512 to set identifier to previously allocated Command Payload. It
5513 is used to set identifier for command when resending Command
5516 * Added silc_command_payload_encode_payload to encode Command
5517 Payload buffer from SilcCommandPayload structure.
5519 * Added silc_argument_payload_encode_payload to encode Argument
5520 payload buffer from SilcArgumentPayload structure.
5522 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Changed WHOIS command to support router connection on server side.
5525 The whois request is always sent to router unless the server is
5526 standalone server. After server has received the reply from the
5527 router will it send the reply to the client.
5529 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5530 broadcast received broadcast packet. The function is used only
5531 by router. The broadcast packet is always sent to the router's
5534 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5535 render given ID to printable string, for log files for example.
5537 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Made basic router to router connections working. At least they
5540 can now connect to each other but nothing really works the way
5541 they are supposed - yet.
5543 * Added new initiator token to RouterConnection configuration
5544 file in silcd/serverconfig.[ch]. It is used to tell whether we
5545 are the initiator to the remote router or whether we'll expect
5546 the other end to connect.
5548 * Moved registering of listener task to silc_server_init, hence
5549 the server starts listenning as soon as it is run, even if it
5550 does not have connections to other routers. Let's see how well
5553 * Changed default connection retry timeouts for more suitable in
5556 * Removed cipher and such arguments from silc_idlist_add_client
5557 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5558 Added new function silc_idlist_add_data to add the keys and stuff
5561 * Added SilcIDListData structure and added it to SilcClientEntry
5562 and SilcServerEntry as their first field in the structure. This
5563 way we can explicitly cast the ID entries to the SilcIDListData
5564 structure and get common data for the entries. In past, we had
5565 to first check what type of connection it is and then cast it to
5566 correct ID entry type. Now, we can directly cast the opaque
5567 pointer to the SilcIDListData (no matter what ID entry it actually
5568 is) and get the data needed.
5570 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5573 in some circumstances even if threre were timeout tasks, though not
5574 IO tasks, but tasks anyway. Now fixed.
5576 * Defined SilcServerConnection structure to hold connection specific
5577 stuff about directly connected servers and routers. The definition
5578 is currently in silcd/server_internal.h. I thought about having
5579 a bit more important role fro this struct but for now it is used
5580 only when connecting to other server (or router actually).
5582 * Added connecting retry support in server when connecting to
5583 router(s). The retry feature implement exponential backoff
5584 algorithm. Also, added SilcServerParams structure to hold default
5585 parameters for server. For now, it include these retry settings
5586 and are hard coded. After server is moded to be as Silc Server
5587 Library this structure will be more important.
5589 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Changed client librarys channel->clients table to SilcList and
5592 changed code accordingly.
5594 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Changed client's channel table to SilcList and changed code
5597 accordingly. Also changed SilcChannelClientEntry to include back-
5598 pointer to the channel so that client entry can use that structure
5599 as list as well and we have fast cross-reference to the channel.
5600 This change dramatically decreased the complexity of channel
5601 handling with client entry and vice versa (removed one extra
5602 loop when searching for channel entry from many functions).
5604 * Changed server->sim from table to SilcDList and changed code
5607 * NAMES command can now be used from user interface. It will show
5608 the user list on the channel, neatly.
5610 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5611 Code now saves realname of the user if it becomes available.
5613 * Renamed configure.in to configure.in.pre and made ./prepare
5614 script to automatically add correct version string to
5615 configure.in which it creates from configure.in.pre.
5617 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5619 * NAMES command reply now shows users mode with the nickname when
5622 * Moved silc_client_ch[u]mode[_char] functions from
5623 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5624 place sucks, they are utility functions and should be in some
5627 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5629 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5632 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Added TRQ (efficient deque and list library) into lib/trq. This is
5637 a very good list library that is currently used in the SILC. Defined
5638 SilcList API over the library because I didn't like the API very
5639 much. See lib/trq/silclist.h for the API and examples of how to
5640 use the API. Fixed various places in the code to use the new
5641 SilcList API. The SilcList is meant for lists that has a structure
5642 already defined as a list. It is not suitable to add just some
5643 context to the list (in TRQ, the context is the list actually).
5645 So, I defined SilcDList that can be used for the purpose where
5646 predefined list structure does not exit. This can be used as
5647 such list. Now some context just can be added to the SilcDList.
5648 Currently this list is not used in the SILC just yet, though there
5649 are a lot places where this can replace dynamically allocated
5650 tables and I will fix these places, later, to use SilcDList.
5651 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5652 and use TRQ internally).
5654 Also fixed some annoying warning messages that the original TRQ
5655 code generated. Also minor changes to TRQ's Makefile.in.
5657 * Added support for querying by Client ID to both WHOIS and
5658 IDENTIFY commands into server, as required by the protocol.
5660 * Removed method function pointers from SilcBuffer structure. They
5661 weren't used to anything and just increased the context size for
5662 no good reason. This change also made silc_buffer_alloc and
5663 silc_buffer_free functions inline functions.
5665 * Disabled command flooding detection support until it's fixed so
5666 that it accepts commands in but does not execute them more than once
5669 * Added silc_net_localhost(), to return local hostname, into
5670 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5671 that must be initialized before calling silc_client_init.
5673 * Added new function: silc_server_send_notify_on_channels to send
5674 notify messages to all channels client has joined. It is assured
5675 that the message is sent only once per client.
5677 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5678 lib/silcutil/silcutil.[ch] as silc_format function. The new
5679 function is generic and is used by server as well, not only by
5680 the logging routines.
5682 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5683 the provided version string was not acceptable. Added new function:
5684 silc_ske_check_version into lib/silcske/silcske.h. The function
5685 must be implemented by the application (client or server) and it
5686 does not reside in the SKE library. The function checks the version
5687 string remote end sent.
5689 * Added back pointers (to opaque context and to SilcSocketConnection)
5690 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5692 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5693 duplicate packet context structure.
5695 * Changed `notify' client operation to send same arguments as client
5696 receives from server except for ID's. ID's are mapped to correct
5697 ID entry and that is returned. Also, if channel entry is not sent
5698 by server but the notify is for channel the channel entry is sent
5699 to application (otherwise application doesn't know that it is for
5700 channel (library gets it from packet's Destination ID)).
5702 * Added silc_client_remove_from_channels into client library to
5703 remove a client from all channels it has joined to. Used when
5704 received SIGNOFF notify from server. Added also new function
5705 silc_client_replace_from_channels to replace old ID entry with
5706 new ID entry on all channels. Used when received NICK_CHANGE
5709 * Fixed ID Cache list handling in silc_idlist_get_client in
5710 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5711 to get (or query) client by ID.
5713 * Updated TODO list.
5715 * Added connection authentication status message defined by the
5716 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5717 support for these into the code in client and server side.
5719 * Added generic function silc_client_send_command to send any command
5720 with variable argument list. Application should use this function
5721 to send commands if the command functions provided by the library
5722 does not suite for the application's user interface needs.
5724 * Added new `failure' client operation. Application is notified about
5725 received failure packet if client is executing a protocol. In this
5726 case the protocol's execution has failed.
5728 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5729 is required by the protocol.
5731 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5732 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5735 * Added status flag to SilcSKE object to indicate realtime status
5736 of the SKE protocol.
5738 * Application receives now exactly same command reply arguments as
5739 the library receives from server. However, if ID is received the
5740 corresponding ID entry is returned to the application (eg. Client
5741 ID is mapped to correct SilcClientEntry entry and that is returned).
5742 Changed command_reply client operation due to this change.
5744 * Changed all ID's in commands and in command replys as ID Payloads.
5745 Change affected both client and server side codes.
5747 All ID's sent in SILC network (with execption of ID's in SILC
5748 Packet header) are sent in ID Payload to support variable length
5751 * Server now notifies nick changes and notifies all clients on
5752 the channels about the new nickname (about the new Client ID,
5755 * Implemented CMODE command to change channel modes. Supports all
5756 channel modes defined by the protocol specs except ban and invite
5757 lists. (Also, private channel key mode is supported but support for
5758 setting private channel key in client is missing, thus, this mode
5759 has no effect on client side (except that server requires that the
5760 client uses private channel key and normal channel traffic does not
5763 Also, invite mode works per se, but INVITE command does not work
5764 yet correctly, so you can set channel as invite only channel but
5765 inviting clients to the channel does not work (it is yet to be
5766 thought what's the best way to do it).
5768 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5769 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5770 Implemented CUMODE command to change user's mode on the channel.
5771 Supports all modes defined by the protocol specs.
5773 * Added NAMES command reply to return users modes on the channel.
5775 * Removed unnecessary and slow ciphers from lib/silccrypt.
5777 * Set SO_KEEPALIVE option to connection sockets by default.
5779 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5781 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5782 redefined the Notify Payload into protocol specs.
5784 * Added silc_id_payload_parse_id to get ID directly from raw
5787 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5790 accept searching by Client ID as well.
5792 * Added support for LEAVE and SIGNOFF notify types in client library.
5794 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5795 to parse ID Payload from raw data.
5797 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Added flags parameter into silc_ske_assemble_security_properties
5800 function in lib/silcske/silcske.[ch].
5802 * Changed notify client operation to fit better for notify messages
5803 sent by server. The notify payload received from server is now
5804 passed to the application (after parsing it to SilcNotifyPayload).
5805 It is application's responsibility to retrieve the arguments
5806 from the payload and show the message the way it wants. The message
5807 sent by server is implementation specific.
5809 * Changed public keys to comply with the protocol specification.
5810 Old public keys are not supported anymore and are not compatible.
5812 * Removed nickname from Channel Payload as the latest draft removed
5813 it. The client must resolve the nickname from the NAMES command
5814 reply received when it joined the channel.
5816 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5818 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Fixed some errors in protocol specification drafts.
5822 * Created lib/silccore/silcnotify.c to implement Notify Payload
5823 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5824 generic payloads described by protocol specifications. The file
5825 includes implementations for ID Payload and Argument Payload.
5827 * Changed Command Payload implementation to use the new Argument
5828 Payload. Changed command_xxxx_payload to command_payload_xxxx
5829 to comply with SILC coding conventions.
5831 * Added suppport for Argument Payload handling in Notify Payload
5832 implementation as protocol requires it. Added the new support
5833 into server and client lib as well.
5835 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added support for multiple nicknames on same channel. [n] is
5838 added locally to the nickname if there are more than one same
5839 nicknames on the channel.
5841 * Server now sends all nicknames that matched WHOIS request.
5842 Client also shows the list received from server.
5844 * Added TOPIC command to client side. User can now set and show
5845 current topic on channel.
5847 * Added MOTD command to client and server. Also, server sends the
5848 motd when client connects to the server.
5850 * Changed version strings to comply ISO 8601.
5852 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Fixed protocol error handling in client library. It should now
5855 cope even if the SKE fails for some reason.
5857 * Made new protocol specification drafts for submitting to IETF.
5859 * Implemented TOPIC command to server in silcd/command.c.
5861 * Added two new notify types into lib/silccore/silcnotify.h:
5862 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5863 notify nickname change and topic setting/change on a channel.
5865 * API change of command_reply operation in client library. The
5866 application gets now the status type received from server as well.
5868 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5872 * Cras fixed and optimized the packet handling even further and
5873 it should work now. Minor change to the prototype of function
5874 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5876 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added new function into lib/silcutil/silcschedule.[ch]:
5879 silc_schedule_with_fd to select() a specified fd. The function
5880 returns after timeout expires or data arrives or goes. The
5881 function is used by packet routines to wait that all data is
5882 received from network.
5884 * Fixed data reading from network in lib/silccore/silcpacket.c.
5885 The code now assures that all data is read from the fd and then
5886 continues packet processing. This was a bug fix since the code
5887 used to drop some data in some circumstances.
5889 * Added new function into lib/silcclient/client.[ch]:
5890 silc_client_start_key_exchange to start key exchange after
5891 connection has been established to server. The code internally
5892 now uses this funtion but its main purpose was to provide it
5893 for applications that perform their own connecting. After
5894 application has created a connection it merely calls this
5895 function to start the key exchange between client and server.
5896 The library takes care of everything else after that.
5898 Updated also lib/silcclient/README to explain the usage of
5901 * Do not send to application information that connection has
5902 been established. Application gets notified it by connect
5905 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Applied cras's patch to add silc_schedule_one function. The
5908 function runs scheduler once and returns.
5910 * Fixed the scheduler after cras messed it up. The timeout
5911 handling works now as it's supposed to work.
5913 * Added into lib/silccore/ silcnotify.h to include notify
5914 message types support. Changed silc_server_send_notify*
5915 functions, in server.[ch], to support those new notify types.
5916 Added the support for the notify types into client library,
5917 as well. Added new notify client operation into ops.h in
5920 * Changed silc_server_packet_send_to_channel to send normal
5921 packets instead of just channel message packets. The function
5922 is now used to send the notify packets to channels. It is not
5923 used to send channel message packets anymore, as server never
5926 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5927 va_arg()s as it seems to require it nowadays. I guess, if SILC
5928 is compiled with older va_arg() the new code should work anyway.
5930 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Splitted core library. Core library (lib/silccore) includes
5933 now only SILC protocol specific core (and common) components.
5934 Created new utility library (lib/silcutil) that includes more
5935 generic purpose stuff. The stuff for util library was taken
5936 from the old core library. This was minor and easy split.
5938 * Created SILC Client Library (lib/silcclient) that includes
5939 implementation of the SILC client without user interface. This
5940 was major move from silc/ directory. The code has been changed
5941 so that it is transparent towards the user interface. The
5942 silc/ directory includes now the same user interface as before
5943 and it uses the new client library. Read lib/silcclient/README.
5944 Basicly, the client library performs everything else related
5945 to SILC except user interface handling. Also, configuration
5946 files are considered to be part of user interface and library
5947 does not handle them.
5949 This change also changed a lot of structures, function naming etc.
5950 Most important change was that SilcClientWindow object was
5951 renamed to SilcClientConnection in the client library. Created
5952 also new file lib/silcclient/ops.h. Also added new files
5953 silc/local_command.[ch] and silc/client_ops.[ch].
5955 All these changes were made to make it easier for user interface
5956 designers to create what ever user interface for the SILC client
5959 It is also expected that the server will be moved to lib
5960 directory as well and SILC Server Library will be created;
5961 sometimes in the future.
5963 * Removed Local commands from lib/silccore/silccommand.h as
5964 they are application specific and new client library does not
5965 handle any of those anymore.
5967 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5968 old client implementation in silc/.
5970 * Added support for callback functions in SILC_LOG_* macros.
5971 Application can now set its own callbacks that will be called
5972 instead of using the default functions that will always print
5973 the debug messages to stderr (or stdout). Also, debugging can
5974 now be disabled by setting silc_debug to FALSE and re-enabled by
5975 setting it to TRUE. Note, that logging will still work even
5976 if debugging is disabled.
5978 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5979 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5980 silc_log_reset_debug_callbacks.
5982 * To enable debugging in silc client one must give now -d
5983 option on command line.
5985 * Changed silc_schedule_init to automatically allocate task queues
5986 if they are not allocated before calling it.
5988 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added GMP 3.1 into math library.
5992 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5995 a channel in SILC network. The packet is used by servers and
5996 routers to notify other routers that user has left a channel.
5997 This little feature was missing until now. Added the feature
5998 to protocol specification as well.
6000 Added functions: silc_server_send_remove_channel_user and
6001 silc_server_remove_channel_user into server.[ch].
6003 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6004 lib/silccore/silcpacket.h. However, they are not implemented
6007 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6009 * Fixed joining to a channel and sending channel messages
6010 between server and router. The channel message sending should
6011 now work inside a cell.
6013 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6015 * Fixed the private message sending between server and router.
6016 The private message sending should now work inside a cell.
6018 * Added silc_server_replace_id into server.[ch] to replace
6019 existing ID in the SILC network.
6021 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6022 and silc_idlist_replace_server_id into idlist.[ch] in server.
6024 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Fixed the server to server connections. Server can again now
6027 connect to router. Router to router connections probably does
6030 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Added dynamic protocol registering support. Now protocols can
6033 registered and unregistered on the fly. Patch by cras.
6035 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Added lib/contrib directory to hold routines that some platforms
6038 don't have but are needed by SILC.
6040 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6041 into lin/contrib to provide getopt() and getopt_long() for
6042 those who don't have it.
6044 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added AWAY command to client. When away message is set and
6047 client receives a private message packet the client automatically
6048 replies to the sender with the away message.
6050 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6051 bug seemed to be the cause of recent problems when compiling
6054 * Added version detection support to SKE protocol specification
6055 and added the new changes to the SKE implementation as well.
6056 There were other minor changes in the SKE protocol as well.
6058 Many changes in lib/silcske/silcske.[ch] and in
6059 lib/silcske/payload.[ch].
6061 * Added ^U functionality, clear input line. Patch from cras.
6063 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Mainly small bugfixes on core library. Fixed some debugging
6066 logging and buffer overflow in silclog.c.
6068 * Updated config.sub and config.guess on the distribution tree.
6070 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Added command lagging support in server. Client may execute
6073 commands now only once in two seconds.
6075 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Optimized packet reception. MAC computation and checking is now
6078 also more optimized. A lot previously duplicated code is now
6079 used as generic by both client and server.
6081 * Fixed key pair generation in clientutil.c
6083 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added into lib/silccore/silcbufutil.[ch] new function;
6086 silc_buffer_realloc.
6088 * Moved generic packet sending/encryption functions to
6089 lib/silccore/silcpacket.[ch] from client and server. Some
6090 rewriting of the functions.
6092 * Moved all generic packet reception/decryption functions to
6093 lib/silccore/silcpacket.[ch] from client and server. The
6094 packet processing is now much cleaner in both client and server.
6095 These were major changes in both client and server.
6097 * Created many common functions in server to do packet sending.
6098 Previously code were duplicated a lot, this has been removed
6101 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Rewrote major parts of the ID cache system. Don't know
6104 whether it is better now or not but at least the API is more
6107 * Major rewrite on ID cache stuff on client because of the ID
6108 cache API changes. Added idlist.c to client.
6110 * Also major rewrite on ID cache stuff on server as well.
6111 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6112 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6113 in hand, instead they are all put into the ID cache system now.
6114 All server_idlist_* routines uses ID cache now instead of
6115 traversing its own lists (those lists does not exist anymore).
6116 SilcIDList though still exists. Also, SilcXXXEntry's are
6119 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Finally made the SKE implementation compliant to the protocol
6122 specification. All mp integers are now binary encoded as
6123 opposed being HEX encoded.
6125 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6128 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6129 functions: silc_[encode/decode]_pem. Also added function
6130 silc_encode_pem_file to PEM encode with newlines ('\n') for
6133 * SILC public keys are now encoded either PEM or binary. Same
6134 option is for private keys as well. By default private keys
6135 are binary encoded and public keys PEM encoded. Silly HEX
6136 encoding were removed.
6138 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6139 function to create fingerprints.
6141 * Fixed a bug in SHA1; does not change the original data anymore.
6143 * Partly implemented INFO command on client and server side.
6144 Fixed CLEAR command. Changes to SERVER command; show current
6145 server(s) when giving command without arguments. Added
6146 VERSION command to client.
6148 * Added check to server that unregistered connections cannot
6149 execute commands (unless it is specificly allowed).
6151 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Fixed screen refresh.
6155 * Fixed channel joining bug from client. On some circumstances
6156 client tried to join to a channel it had already joined.
6158 * Added public key verification process into client's protocol.c.
6159 The client now verifies the public key from user and saves
6160 it into ~./silc/serverkeys/ directory.
6162 Added into: clientutil.[ch]: silc_client_verify_server_key.
6164 * Changed SKE protocol's silc_ske_initiator_finish function
6165 to accept callback function that verifies the received public
6166 key. Removed old silc_ske_verify_public_key function.
6168 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6171 silc_pkcs_private_key[_data]_set.
6173 * Made the password and public authentication more cleaner in
6174 server's protocol.c.
6176 * Removed historic and obsolete protocol `channel_auth' from
6177 both client and server.
6179 * Removed wrong way of sending command status messages from
6180 server to client in server's command.c. The old way violated
6181 protocol specification.
6183 Changes to silccore/silccommand.[ch]: removed
6184 silc_command_encode_status_payload -> not needed anymore,
6185 changed silc_command_encode_payload_va to accept extra
6186 argument on variable argument list. The argument type must
6187 now be provided to the function. Also, added new function:
6188 silc_command_encode_reply_payload_va which is same as
6189 normal command_encode_payload_va except command status type
6190 is provided as extra argument.
6192 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Added ~./silc directory handling. The directory includes the
6195 public and private keys for the client.
6197 Added silc_client_check_silc_dir, silc_client_create_identifier
6198 and silc_client_load_keys.
6200 * Implemented SILC protocol compliant public key. Added public
6201 and private key saving to and loading from files.
6203 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6204 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6205 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6206 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6207 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6209 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6210 silc_pkcs_load_[public/private]_key.
6212 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Added silc_server_get_route (route.[ch]) to get connection
6215 data for the fastest route for given ID.
6217 * Implemented INVITE command on client and server. The command
6218 were re-defined in the SILC Protocol Specification and the
6219 implementation now complies with the specification.
6221 * Implemented PING command on client and server.
6223 * Implemented NAMES command on client and server. The server side
6224 supports currently only normal server not router server yet.
6225 Some changes to NAMES definition in SILC protocol specification.
6227 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Implemented LEAVE command on client and server.
6231 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6232 again. This change was made to the protocol as well. Server
6233 should not violate the protocol specification anymore.
6235 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6238 was tested. SOCKS4 was not but should work anyway.
