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

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

454 * Check that newsize in silc_buffer_realloc is larger than
455 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
457 * Added better monitor of file transfers. It now monitors
458 key agreement protocol during the file transfer too. Added
459 error reporting too. Affected files
460 irssi/src/silc/core/silc-servers.c,
461 irssi/src/fe-common/silc/module-formats.[ch].
463 * Wrote a help file for FILE command.
465 * Added silc_rng_global_get_byte_fast to get not-so-secure
466 random data as fast as possible. Random data is read from
467 /dev/urandom if available and from the SILC RNG if not
468 available. It is used in padding generation. Affected file
469 lib/silccrypt/silcrng.[ch].
471 * All packets in client library are now processed synchronously.
472 Optimized packet processing a lot. Affected file
473 lib/silcclient/client.c.
475 * All server connection packets are processing synchronously
476 now in server, to optimize packet processing. Affected file
479 * Include files are installed now only in Toolkit distribution
480 if make install is given. Affected files: all Makefile.am's.
482 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
484 * Assure that silc_client_notify_by_server_resolve does not
485 resolve the client information multiple times. If it cannot
486 be found by the first it cannot be found at all. Affected
487 file lib/silcclient/client_notify.c.
489 * Fixed WHOWAS command reply calling. Affected file
490 lib/silcclient/command_reply.c.
492 * Removed all references to silc_idlist_get_client from the
493 Irssi SILC client since that call is internal call used by
494 the library. The Irssi SILC client will use now client
495 retrieval functions found in silcapi.h.
497 * Fixed a bug in resolving nickname info before sending
498 private message. It used freed memory. Affected file
499 irssi/src/silc/core/silc-servers.c.
501 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
503 * Assure my_channels statistics cannot go negative in server.
504 Affected files silcd/server.c, silcd/server_util.c.
506 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
508 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
510 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
512 * Win32 Toolkit changes. Affected files
513 win32/silc.dsw, win32/libsilc/libsilc.def,
514 win32/libsilcclient/libsilc.def,
515 lib/silcutil/silcutil.c, and
516 lib/sftp/sftp_fs_memory.c.
518 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
520 * Added silc_net_localip to return local host's IP address.
521 Affected file lib/silcutil/silcnet.[ch].
523 * If key exchange or rekey protocol is active for a connection
524 parse all packets syncronously since there might be packets
525 in packet queue that we are not able to process without first
526 processing packets before them. Affected file silcd/server,
527 lib/silcclient/client.c.
529 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
530 whether library should continue processing the packet.
531 Affected file lib/silccore/silcpacket.h.
533 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
534 SilcSFTPMonitorData to SFTP server to monitor various
535 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
536 lib/silcsftp/sftp_server.c.
538 * Added silc_file_size to return file size. Affected file
539 lib/silcutil/silcutil.[ch].
541 * Implemented the file transfer support for the client library.
542 Added preliminary support for simple client to client one-file
543 transmission. Affected file lib/silcclient/client_ftp.c,
544 lib/silccilent/client.[ch].
546 * Added new local command FILE to the Irssi SILC Client.
547 It is used to perform the file transfer. It has subcommands
548 SEND, RECEIVE, SHOW and CLOSE. Affected files
549 irssi/src/silc/core/client_ops.c,
550 irssi/src/silc/core/silc-server.[ch].
552 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
554 * Relay the SILC_PACKET_FTP in the server. Affected files
555 silcd/server.c and silcd/packet_receive.c.
557 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
559 * Renamed silc_file_read and silc_file_write to functions
560 silc_file_readfile and silc_file_writefile. Added function
561 silc_file_open and silc_file_close. Affected files
562 lib/silcutil/silcutil.[ch].
564 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Resolve the client info when received private message or
567 channel message for a client which nickname we don't know.
568 Affected files lib/silcclient/client_prvmsg.c and
569 lib/silcclient/client_channel.c.
571 * Do not crash in /KEY if client is not connected. Affected
572 file irssi/src/silc/core/silc-channels.c.
574 * Added SilcClientStatus field to the SilcClientEntry in the
575 lib/silcclient/idlist.h.
577 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
578 is incomplete and is being resolved, it won't be resolved
581 Make sure also that USERS command reply does not resolve
582 twice information. Affected file is
583 lib/silcclient/command_reply.c.
585 Make sure that silc_client_get_clients_by_list does not
586 resolve twice same information.
588 * Check for valid client->id in the silc_server_free_client_data.
589 Affected file silcd/server.c.
591 * Fixed /GETKEY nick@server not to crash if the server entry
592 is not found. Affected file lib/silcclient/command.c.
594 * Fixed the silc_server_check_cmode_rights to check the
595 requested modes correctly. Affected file silcd/command.c.
597 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
599 * Better checks for non-printable chars in nick added.
600 Affected file silcd/command.c.
602 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Call the silc_server_udpate_servers_by_server in the
605 primary router that comes back online in the backup resuming
606 protocol. Otherwise it routes packets wrong. Affected file
607 silcd/server_util.[ch], silcd/server_backup.c.
609 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
611 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
612 lib/silcutil/silcbuffmt.[ch].
614 * Redefined the SILC packet header to include the padding
615 length. Affected file lib/silccore/silcpacket.[ch].
617 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
618 length for maximum padding up to 128 bytes). Affected
619 file lib/silccore/silcpacket.h.
621 * Removed all backwards support for old 0.5.x MAC thingies.
622 The SILC packet header change makes it impossible to be
623 backwards compatible.
625 * Send the ENDING packet with timeout in the backup resuming
626 protocol. This is to assure that all routers has connected
627 to the primary router. Affected file silcd/server_backup.c.
629 * Changed the RNG to take the first IV from random data. It
630 used to take it from zero actually. Changed the RNG also
631 to use /dev/urandom during session. /dev/random is used
632 in initialization. Affected file lib/silccrypt/silcrng.[ch].
634 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
636 * Changed the SILC packet header to have the first two bytes
637 (the packet length) encrypted. Affected files aroung the
638 code tree, lib/silccore/silcpacket.[ch]. Removed the
639 SilcPacketCheckDecrypt callback. It is not needed anymore
640 since the silc_packet_receive_process will determine now
641 whether the packet is normal or special.
643 * Implemented the unidirectional MAC keys. Affected files
644 lib/silcske/silcske.c, silcd/protocol.c and
645 lib/silcclient/protocol.c.
647 * Implemented the packet sequence number to the MAC computation.
648 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
649 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
650 lib/silcclient/protocol.c.
652 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
654 * Allow backup router to announce servers. All servers
655 announced by backup router are added to the global list
656 automatically. Update hte server's socket to our primary
657 router also when backup router announces a server.
658 Affected file silcd/packet_receive.c.
660 * Do not update the client->router in the function
661 silc_server_udpate_clients_by_server if the client is on
662 global list. We might fail to find any specific server
663 for locally connected clients and local cell clients. They
664 should still use the `from' and not `to' as client->router.
665 This fixes backup router resuming protocol. Affected file
668 * Decrease channel statistics count only if the channel
669 deletion worked. Affected files are silcd/server.c and
672 * Added silc_server_update_servers_by_server to update origin
673 of all server entries. Used during backup router protocol.
674 Affected files silcd/server_util.[ch], silcd/server.c. and
675 silcd/backup_router.c.
677 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
678 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
679 silc_hmac_get_hash and silc_hmac_get_name. Affected file
680 lib/silccrypt/silchmac.c.
682 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Assure that router cannot reroute the same channel message
685 to the sender. Affected file silcd/packet_receive.c.
687 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Made better checks that the channel message is not sent
690 to the router it came from. Affected file is
691 silcd/packet_send.c. Fixed memory leak too.
693 * Announce informations for incoming router connection, but
694 only after checking if it is replaced by backup router.
695 Affected file silcd/packet_receive.c.
697 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
699 * Fixed the backup resuming protocol to work in multiple
700 router environment. Affected file silcd/server_backup.c.
702 * Route packet only to one router in the function
703 silc_server_packet_send_to_channel. Affected file is
706 * Fixed silc_server_send_notify_dest to set the broadcast
707 flag. Fixed the silc_server_send_notify_topic to actually
708 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
709 Affected file silcd/packet_send.c.
711 * Changed the SFTP Filesystem interface. Changed the
712 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
713 the filesystem operation function. The SilcSFTPFilesystem
714 is now a context that is allocated by all filesystem allocation
715 functions and it already includes the operations structure
716 and filesystem specific context. It is given as argument
717 now to the silc_sftp_server_start. This made the interface
718 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
719 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
721 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
723 * Changed the backup router adding and getting interfaces
724 in the server. The router that will be replaced by the
725 specified backup router is now sent as argument. Affected
726 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
729 * Added silc_net_addr2bin_ne to return the binary form of
730 the IP address in network byte order. Affected files
731 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
733 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Check for existing server ID in silc_server_new_server
736 and in silc_server_connect_to_router_final and remove the
737 old entry if it exists. Affected file silcd/packet_receive.c,
740 * Send the channel message always to only one router, either
741 in upstream or downstream. Affected file is
744 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Wrote the definition of the backup resuming protocol to the
747 protocol specification.
749 * Removed one redundant channel key generation from normal
750 server during joining procedure. Removed one redundant
751 channel key sending from server to router during joining
752 procedure. Affected file silcd/command.c.
754 * Made minor bugfixes to the backup router resuming protocol.
755 Affected file silcd/server_backup.c, server.c.
757 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
759 * Added --disable-asm configuration option. Affected files
760 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
763 * Implemented the backup resuming protocol that is used to
764 resume the primary router position in the cell after the
765 primary router comes back online. Affected files
766 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
767 and silcd/server_util.[ch].
769 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Sleep two (2) seconds after sending QUIT command to server.
772 Affected file lib/silcclient/command.c.
774 * Assure that if outgoing data buffer is pending do not force
775 send any data. Affected file silcd/packet_send.c.
777 * Assure that if outgoing data buffer is pending do not force
778 send any data. Affected file lib/silcclient/client.c.
780 * Implemented the backup router support when the primary router
781 goes down. The servers and routers can now use the backup
782 router as new primary router without loosing connectivity.
784 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
786 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
787 in the server to indicate disabled entry. All data read
788 from the connection will be ignored and no data is sent
789 for entry that is disabled. Affected files are
790 silcd/idlist.h, silcd/server.c.
792 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Created SFTP client and server test programs in the
795 lib/silcsftp/tests directory.
797 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Implemented memory filesystem (virtual filesystem) for
800 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
803 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Implemented the SFTP (SSH File Transfer Protocol) to the
806 lib/silcsftp. It includes SFTP client and SFTP server
809 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
811 * Moved lib/silccore/silcprotocol.[ch] to the
812 lib/silcutil library.
814 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
815 take variable argument list pointer as argument. Affected
816 file lib/silcutil/silcbuffmt.[ch].
818 * Added silc_buffer_set function that is used to set data
819 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
820 Affected file lib/silcutil/silcbuffer.h.
822 * Changed various routines in the core library to use the new
823 silc_buffer_set instead of allocating new buffer only for
826 * Added 64-bit value formatting and unformatting support to the
827 silc_buffer_[un]format routines. Affected file is
828 lib/silcutil/silcbuffmt.[ch].
830 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
831 to includes/bitmove.h.
833 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
835 * Fixed channel user mode saving in client library. Affected
836 file lib/silcclient/command[_reply].c.
838 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Defined the file transfer to the SILC Protocol. Added
841 new packet type SILC_PACKET_FTP and defined File Transfer
842 Payload. The mandatory file transfer protocol is SFTP
843 (SSH File Transfer Protocol). Affected file in addition
844 of the internet draft is lib/silccore/silcpacket.h.
846 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
847 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
848 is used as part of backup router protocol when the primary
849 router of the cell is back online and wishes to resume
850 the position as primary router.
852 * Redefined the MAC generation keys in the protocol. The
853 same key is not used anymore in both direction. Both
854 direction will now use different keys for sending and
855 receiving. This fixes a potential security flaw. This
856 change causes incompatibilities in the protocol.
858 * Redefined also the MAC computation from the packet.
859 An packet sequence number is now added to the MAC
860 computation. This prevents possible replay attacks against
861 the protocol. This change too causes incompatibilities
864 Added `sequence' field to the SilcPacketContext to hold
865 the current sequence number for the packet.
867 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
869 * Added `created' field to the SilcIDListData in the file
870 silcd/idlist.h to indicate the time when the entry was
873 * Added `created' field to the SilcChannelEntry too. Affected
876 * Added `creation_time' aguments to all the announcement functions
877 in the server. If it is provided then only the entries that
878 was created after the provided time frame are actually
879 announced. Affected file silcd/server.[ch].
881 * The protocol says that the Channel ID's IP address must be
882 based on the router's IP address. Added check for this in
883 the silc_server_new_channel when processing incoming New Channel
884 Payload. Affected file silcd/packet_receive.c.
886 * Print out the correct version with --version in SILC client.
887 Affected file irssi/src/silc/core/silc-core.c.
889 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Fixed WHOWAS command to check for completnes of the client
892 entry always, not just when the command is coming from client.
893 Affected file silcd/command.c.
895 * Added new function silc_server_packet_queue_purge to purge the
896 outgoing data queue to the network. After the function returns
897 it is guaranteed that the outgoing packet queue is empty.
898 Affected file silcd/packet_send.[ch].
900 * Purge the outgoing packet queue in the rekey protocol's final
901 callback to assure that all rekey packets go to the network
902 before quitting the protocol. Affected file silcd/server.c.
904 * Added silc_client_packet_queue_parse as similar function as
905 in server to the client library. The affected file is
906 lib/silcclient/client.c.
908 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Splitted silcd/server.c and created silcd/server_util.[ch]
911 for utility functions.
913 * Added new socket flag SILC_SF_DISABLED to indicate that the
914 connection is open but nothing can be sent to or received from
915 the connection. Affected file lib/silcutil/silsockconn.[ch].
916 The checking for disabled socket is checked in the low level
917 silc_socket_write and silc_socket_read functions.
919 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Allow only nicknames and channel names that fits into the
922 7-bit unsigned char ASCII set. Affected file silcd/command.c.
924 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
926 * When processing JOIN command reply in server check that if
927 the channel exists in our global list we'll move it the local
928 list. Affected file silcd/command_reply.c.
930 * Fixed the check whether client is joined on the channel already
931 in JOIN command. Affected file lib/silcclient/command.c.
933 * Fixed the JOIN command reply to check whether the channel
934 already exists. Affected file lib/silcclient/command_reply.c.
936 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Added silc_ske_status_string to map the SKE error numbers
939 to readable strings. The affected files are
940 lib/silcske/silcske[_status].[ch].
942 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
944 * Do not show the private channels on the WHOIS channel list
945 as it is not allowed by the protocol. The affected file is
948 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Assure that the packet length digged from the actual packet
951 is something sensible in the silc_packet_decrypt_rest_special
952 in lib/silccrypt/silcpacket.c.
954 * Free and NULL the allocated pointer in silc_hmac_alloc if
955 the HMAC allocation fails. The affected file is
956 lib/silccrypt/silchmac.c.
958 * Print the selected security properties to the log files in
959 the server. Affected file silcd/protocol.c.
961 * Add SKE's reference counter even if calling the completion
962 callback manually. Otherwise it goes negative, although it
963 does not cause any problems. The affected file is
964 lib/silcske/silcske.c.
966 * Remove the client entry with short timeout after giving the
967 KILL command. Affected file lib/silcclient/command.c.
969 * Fixed to send error reply in WHOIS and IDENTIFY commands in
970 case all found clients are already disconnected (WHOWAS would
971 found them) in the server. Affected file silcd/command.c.
973 * Update the last_receive (time of last data received) to be
974 updated only when received private or channel message so that
975 the idle time showed in WHOIS makes more sense.
977 * Added boolean field `valid' in to the SilcClientEntry in the
978 client library to indicate whether the entry is valid or not.
979 This fixes the nickname change bug on channel when changing
980 the nickname to be same than the old (like nick to Nick) the
981 nickname formatter doesn't set the new nick anymore to Nick@host.
982 Affected file lib/silcclient/idlist.[ch].
984 * Now actually fixed the nickname changing on disconnection.
985 Added new function silc_change_nick to the Irssi SILC Client.
986 Affected file irssi/src/silc/core/client_ops.c,
987 irssi/src/silc/core/silc-nicklist.[ch].
989 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Check that the public key exists in the GETKEY command before
992 trying to encode it. Affected file silcd/command.c.
994 * Print some notifications on received public keys with GETKEY
995 command in the Irssi SILC Client. Affected files are
996 irssi/src/fe-common/silc/module-formats.[ch],
997 irssi/src/silc/core/client_ops.c.
999 * Use IDENTIFY command to resolve the server information in the
1000 GETKEY command instead of INFO command. Affected file
1001 lib/silcclient/command.c.
1003 * All command reply functions in the client library now calls
1004 the pending command reply callbacks even if an error has
1005 occurred. The server has done this a long time and now it was
1006 time to move the client library to this as well. Now all
1007 errors can be delivered back to the pending command reply
1008 callbacks if necessary. Affected files are
1009 lib/silcclient/command[_reply].[ch].
1011 * Change the nickname on disconnection back to the username
1012 because in reconnect the server will enforce it to it anyway.
1013 Affected file irssi/src/silc/core/silc-servers.c.
1015 * Fixed a config file parsing bug in the Irssi SILC client.
1016 Affected file irssi/src/silc/core/clientconfig.c.
1018 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * When printing the channel mode on JOIN, verify that the
1021 channel key and channel's HMAC are valid. Affected file
1022 irssi/src/silc/core/client_ops.c.
1024 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1027 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1028 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1030 * Removed channel key rekey task deleting from the function
1031 silc_server_save_channel_key. Affected file silcd/server.c.
1032 Added explicit timeout task context instead that is used to
1033 delete the task if we are registering a new task before the
1034 new task has elapsed.
1036 * When channel key rekey occurs the client library now saves
1037 the old channel key for a short period of time (10 seconds) and
1038 is able to use it in case some is still sending channel
1039 messages encrypted with the old key after the rekey. Affected
1040 file lib/silcclient/[idlist.h|client_channel.c].
1042 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Added check to the silc_server_new_id_real to not accept
1045 new ID if it is the sender's own ID. Affected file is
1046 silcd/packet_receive.c.
1048 * Assure that we do not announce ourself or the one we've
1049 sending our announcements when we're router and are announcing
1050 servers to our primary router. Affected file silcd/server.c.
1052 * Fixed silc_server_command_identify_check_client to assemble
1053 correct WHOIS packet. It send corrupted WHOIS packet and
1054 caused problem with router to router connections. Affected
1055 file silcd/command.c.
1057 Fixed also silc_server_command_whois_check the same way
1058 as for the IDENTIFY command.
1060 * Added new SilcIDListStatus to the server in the SilcIDListData
1061 structure. The status now includes the current status of
1062 the entry (like registered, resolved etc.). Affected file
1063 silcd/idlist.[ch]. Defined a bunch of different status types
1064 as well. This replaced the old boolean registered field as well.
1066 Added resolve_cmd_ident field to the SilcClientEntry structure
1067 too so that if the entry is for example being resolved so
1068 another command may attach to the same pending command reply
1069 without requiring to resolve the same entry again. This concept
1070 should optimize the WHOIS and the IDENTIFY resolving under
1071 heavy load by taking away unnecessary resolving for entries
1072 that are being resolved already.
1074 Added support for adding multiple pending commands for one
1075 command idenfier. Affected file silcd/command[_reply].[ch].
1077 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1078 before deleting the data. Otherwise the hash table will have
1079 freed data in comparison functions. Affected file is
1080 silcd/command_reply.c.
1082 * Fixed silc_idlist_replace_client_id to add the new entry to
1083 the cache with NULL nickname. Otherwise there will be invalid
1084 memory as the nickname after the nickname is freed. Affected
1085 file silcd/packet_receive.c.
1087 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1088 saved into wrong slots because the previous number of entries
1089 was not taken into account. Affected file silcd/idlist.c.
1090 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1092 * If we are router and we receive JOIN notify to a channel that
1093 does not have any users then notified client is marked as the
1094 channel founder, as it is it. The affected file is
1095 silcd/packet_receive.c
1097 * Added to the extended hash table API's table_del_*ext functions
1098 the destructor as argument too, so that the caller can decide
1099 which destructor to use or whether to use destructor at all.
1100 Affected file lib/silcutil/silchashtable.[ch].
1102 * Fixed ID Cache purging. It actually deleted the entries from
1103 the hash table after the data was freed. The hash table ended
1104 up comparing freed memory. The affected file is
1105 lib/silccore/silcidcache.c.
1107 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Fixed Irssi SILC client's KILL command's HELP syntax.
1111 * The USERS command now resolves the detailed user information
1112 if the userinfo field is missing. Affected file is
1113 lib/silcclient/command_reply.c.
1115 * Do not print error in silc_file_read if the read file does
1116 not exist. Just silently return NULL. Affected file is
1117 lib/silcutil/silcutil.c.
1119 * Fixed the silc_log_output to not wine about NULL filename
1120 and to not create some bogus " " filename. Affected file is
1121 lib/silcutil/silclog.c.
1123 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Fixed various printing bugs on the user interface in the
1126 Irssi SILC Client. Minor changes that were forgotten from
1129 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Fixed the configure.in.pre and the compilation and distribution
1132 environment to support the new autoconf 2.52. That version is
1133 now required to compile the CVS trunk.
1135 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1137 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1138 to generally parse user@fqdn format strings. Affected file
1139 lib/silcutil/silcutil.c.
1141 * Added nickname_format and nickname_force_format fields to the
1142 SilcClientParams structure. The first one defines the format
1143 for the nicknames that the library will enforce if the receives
1144 multiple same nicknames. The second one is boolean value and
1145 can be used to force the library to always enforce the format
1146 to the nicknames regardles whether there are multiple nicknames
1147 or not. This configurable formatting was employed to flexibly
1148 support accessing multiple nicknames from the user interface.
1149 The userinterface can now set the nicknames to what ever format
1150 they prefer. Affected file lib/silcclient/silcapi.h.
1152 Added function silc_client_nickname_format to the file
1153 lib/silcclient/idlist.c. It performs the nickname formatting.
1155 Added new field `hostname´ to the SilcClientEntry context.
1156 It holds the hostname of the client. Affected file is
1157 lib/silcclient/idlist.h.
1159 * Irssi SILC Client sets the nicknames in nick@hostn format.
1160 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1161 irssi/src/silc/core/silc-core.c.
1163 The WHOIS printing now also shows both the real nickname and
1164 the formatted nickname so that user knows how to access the
1165 user if there are multiple same nicknames cached. Affected
1166 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1167 printing formatting too to take the hostname now as a separate
1168 argument. The Affected file is
1169 irssi/src/fe-common/silc/modules-formats.[ch].
1171 * Changed the silc_client_get_clients_local to accept the formatted
1172 nickname as argument. It accepts the real nickname too but the
1173 formatted nickname can be used to find the true entry from
1174 multiple entries. Affected file lib/silcclient/silcapi.h and
1175 lib/silcclient/idlist.c.
1177 * Added nickname_format_parse field to the SilcClientParams.
1178 It is a callback function provided by the application to parse
1179 the nickname out of the formatted nickname string. The library
1180 calls it to get the nickname from the formatted string. Since
1181 the application generally knows better the format of the nickname
1182 string it parses it instead of the library, even though library
1183 encodes the formatted string. If the callback function is not
1184 provided then the library will use the string as is. The
1185 affected file is lib/silcclient/silcapi.h.
1187 * All the nickname strings passed to the client library in
1188 commands are now expected to be formatted nickname strings.
1189 If the command does not support the formatted nickname string
1190 it will assume that the sent string is the actual nickname.
1191 Affected file lib/silcclient/command.c.
1193 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1195 * Added public key authentication support to OPER and SILCOPER
1196 commands in the client library. Affected file is
1197 lib/silcclient/command.c.
1199 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Changed the get_auth_methdod client operation to be asynchronous.
1202 It can be async if the application resolves the authentication
1203 method from the server during the negotiation. Added new
1204 SilcGetAuthMeth completion callback that the application will
1205 call after resolving the authentication method.
1207 Added function silc_client_request_authentication_method that
1208 the application can use to resolve the authentication method
1209 from the server. Added also SilcConnectionAuthRequest callback
1210 that the library will call after the server has replied. The
1211 application can call this function if it does not know the
1212 current authentication method.
1214 Affected files are lib/silcclient/client.c and
1215 lib/silcclient/silcapi.h.
1217 * The Irssi SILC client now automatically resolves the authentication
1218 method incase any configuration information is not present (and
1219 currently there never is). The affected file is
1220 irssi/src/silc/core/client_ops.c.
1222 * Fixed public key authentication from the client library.
1223 Affected file lib/silcclient/protocol.c. Changed also the
1224 protocol specification about the public key authentication in
1225 the connection authentication protocol. The actual data to be
1226 signed is now computed with a hash function before signing.
1228 * Fixed the public key authentication from the server as well.
1229 Affected file silcd/protocol.c.
1231 * Removed the mlock()'s from the memory allocation routines.
1232 Affected file lib/silcutil/silcmemory.c. The ./configure does
1233 not check anymore for the mlock(). Affected file is
1236 * Fixed USERS command in server to allow the execution of the
1237 command for private and secret channels if the client sending
1238 the command is on the channel. Affected file silcd/command.c.
1240 * Fixed silc_client_get_clients_local to return the clients
1241 count correctly. It could return wrong value. Affected file
1242 lib/silcclient/idlist.c.
1244 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1247 types. The assembler optimizations seemed not to like 64-bit
1248 data types. The assmebler optimizations thus are now enabled
1249 also for BSD systems as opposed to only enable them for Linux.
1251 * Do not check for threads at all on BSD systems. Affected
1252 file configure.in.pre.
1254 * Removed -n and -h options from the Irssi SILC Client since
1255 they are not used in silc.
1257 * Fixed the prime generation to assure that the first digit
1258 of the generated random number is not zero since our conversion
1259 routines does not like number strings that starts with zero
1260 digit. If zero digit is seen the random number is regenerated.
1261 This caused some corrupted RSA keys when the zero first digit
1262 was met. Affected file lib/silcmath/silcprimegen.c.
1264 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Fixed WIN32 configuration in the ./configure script.
1267 Fixed to include xti.h on environments that has it.
1268 Patches by Carsten Ilchmann and andrew.
1270 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Changed the silc_id_create_client_id to be collision
1273 resistant. It is now assured that there cannot be created
1274 two same client ID's. I suspect that some weird bugs in
1275 the server were actually caused by duplicate Client IDs.
1276 Affected file silcd/serverid.[ch]. A router receiving
1277 new ID now also assures and informs the sending server
1278 if the ID caused collision.
1280 * Changed the silc_id_create_channel_id to also assure that
1281 there are no collisions.
1283 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Statement about ignoring the Mutual Authentication flag when
1286 performing rekey with PFS was a bit misleading. It is ignored
1287 if it was set in the initial negotiation, it cannot be even
1288 set in the rekey. Fixed in the ke-auth draft. Started the
1289 new versions of the protocol drafts in the doc/.
1291 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Fixed a bug in silc_client_command_identify_save when saving
1294 new channel information. The channel name was no duplicated
1295 and caused crash on exit. Affected file is
1296 lib/silcclient/command_reply.c.
1298 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1300 * Fixed the getkey command handling in the server. Send just
1301 empty OK reply to the sender if the key could not be fetched
1302 (but everything else was ok, like the key just was not available).
1303 Changed the public key parameter to optional in the protocol
1304 specs so that empty OK reply can be sent. Affected file
1307 Added a message to Irssi SILC client to tell to user if the
1308 server did not return a public key.
1310 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Fixed a channel key regeneration bug. It registered new
1313 timeout tasks exponentially until all system resources were
1314 used. Affected file silcd/server.c.
1316 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * Added the SILC Document generator to the scripts/silcdoc.
1319 It can be used to generate the Toolkit Reference Manual out
1320 of the source tree. Internally it will also use the RoboDoc
1321 generator now imported in util/robodoc.
1323 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Added couple of return's in rekey protocol if error orccurred
1326 during the protocol. The execution must be terminated.
1327 Affected file silcd/protocol.c. Also, terminate the protocol
1328 always with timeout.
1330 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * The client's Client ID was created initally from the wrong
1333 nickname (it could have been in format nick@host) in the
1334 silc_server_new_client. Affected file silcd/packet_receive.c
1336 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Added some SILC_LOG_ERROR's to various error conditions
1339 if client could not be added to ID cache. Affected files
1340 silcd/packet_receive.c and silcd/server.c.
1342 * When client's sock->user_data is freed, NULL also the
1343 client->router and client->connection pointers. Added check
1344 for these pointers being NULL to various places around the
1345 code. Affected file silcd/server.c.
1347 * Added client->data.registered == TRUE checks to various
1348 places around the code to assure that unregistered client's
1349 are not handled when it is not allowed. Affected file
1352 * Added `bool registered' fields to all
1353 silc_idlist_[server|client]_get_* routines to indicate whether
1354 the fetched client needs to be registered or not. Affected
1355 file silcd/idlist.[ch].
1357 * Add your own entry as registered to the ID cache in the
1358 server. Affected file server.c.
1360 * Fixed a bug in silc_server_new_server. The SilcServer was
1361 set as the new server's context instead of SilcServerEntry.
1362 This naturally caused some weird bugs.
1364 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Do not delete the channel rekey task when adding it
1367 for in silc_server_create_channel_key.
1369 * Changed the silc_server_create_channel_key to return
1370 TRUE or FALSE to indicate the success of the channel key
1373 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Fixed MSVC++ project files and added missing files to
1376 Makefiles under win32/.
1378 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Do not add TCP_NODELAY flag if the operating system
1381 does not have it defined. Affected files are
1382 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1384 * Fixed buffer overflow from Irssi SILC Client. Affected
1385 file irssi/src/fe-common/core/themes.c.
1387 * Fixed double free in client library in the file
1388 lib/silcclient/client.c when disconnecting from server.
1390 * Applied double free patch from cras to Irssi SILC client.
1391 Affected files irssi/src/core/[modules/expandos].c
1393 * Fixed the disconnection handling to Irssi SILC Client.
1394 The application must call silc_client_close_connection
1395 in ops->connect client operation in case of failure of
1396 the connection. Affected file is
1397 irssi/src/silc/core/client_ops.c.
1399 * Do not set sock->protocol to NULL in the function
1400 silc_client_close_connection after executing the protocol's
1401 final callback since the sock might not be valid anymore.
1402 Affected file lib/silcclient/client.c.
1404 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Do not enable SILC_THREADS if the linking with libpthread
1407 did not happen. Affected file configure.in.pre.
1409 * Added notion to protocol specification that server must
1410 verify the sent authentication payload with CMODE when
1411 setting the channel founder key. Implemented it to the
1412 server. Affected file silcd/command.c.
1414 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Added _EXTRA_DIST SILC distribution variable to the
1417 distributions file. It is used to conditionally add extra
1418 files or directories to the specific distribution. Affected
1419 files ./prepare, Makefile.am.pre and distributions.
1421 Removed the `_' from the start of the distribution names.
1424 * Added README.WIN32 for instructions to compile the Toolkit
1427 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Fixed a double free in disconnection in the server. Affected
1430 file is silcd/server.c.
1432 * Fixed the lib/silcske/groups.c to work now also with GMP
1433 MP library. The string conversion did not work when using
1434 specific base and the base is indicated in the string as well.
1436 * Created win32/ directory which now includes MSVC++ specific
1437 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1438 It will appear only in the toolkit distribution
1440 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Changed the key material distribution function in case when
1443 the hash output is too short. The data is now concatenated
1444 a bit differently than it used to. Made the change to the
1445 SKE protocol specification.
1447 * Added better GMP detection to configure.in.pre. A patch
1450 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Fixed a minor bug in SKE that might cause some problem on
1453 some platforms. Affected file lib/silcske/silcske.c.
1455 * Added the cookie checking for initiator in the SKE. It checks
1456 that the responder returns the sent cookie unmodified. The
1457 affected file is lib/silcske/silcske.c. Added new SKE
1458 error type INVALID_COOKIE that can be sent during the
1459 negotiation. Fixed some memory leaks as well.
1461 * Added the "invalid cookie" error message to Irssi SILC client's
1464 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Added `task_max' field to the SilcClientParams to indicate
1467 the maximum tasks the scheduler can handle. If set to zero,
1468 default values are used. Affected file lib/silcclient/silcapi.h.
1470 * Fixed memory leaks in silc_client_close_connection. Affected
1471 file lib/silcclient/client.c.
1473 * Added silc_client_del_client_entry to client library to free
1474 all memory of given client entry. Affected file is
1475 lib/silcclient/idlist.[ch].
1477 * Added new functions silc_client_del_channel and
1478 silc_client_del_server to delete channel and server entries.
1479 Affected file lib/silcclient/[silcapi.h/idlist.c].
1481 * Removed silc_client_del_client_by_id from silcapi.h.
1483 * Fixed the INFO command to return the server's own info
1484 correctly when querying by Server ID. Affected file is
1487 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Removed the non-blocking settings in WIN32 code in the
1490 silc_sock_[read/write] and added SleepEx instead. Affected
1491 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1492 of input data is now checked with FIONREAD and ioctlsocket.
1494 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Call silc_schedule_task_del_by_context in the
1497 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1498 Affected file lib/silccore/silcprotocol.c.
1500 * Call silc_protocol_cancel for active protocols in the
1501 silc_server_close_connection if the funtion
1502 silc_server_free_sock_user_data has not been called.
1503 Affected file silcd/server.c.
1505 * Generic tasks cannot be deleted using the del_by_fd
1506 task deleting function since generic tasks does not match
1507 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1509 * Added a notion to SILCOPER help file that the SILCOPER works
1510 only on router server, not on normal server.
1512 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Added for WIN32 support for the new scheduler as well.
1515 Affected file lib/silcutil/win32/silcwin32schedule.c.
1517 * Fixed the SHA1 implementation to work on various platforms.
1519 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1522 API. It is part of the scheduler now. Everything else is
1523 as previously but some functions has changed their names.
1524 Checkout the lib/silcutil/silcschedule.h for the interface.
1525 Updated all applications to use the new interface. Affected
1526 files are lib/silcutil/silcschedule.[ch].
1528 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Found a bug in the SKE implementation. The HASH value,
1531 specified by the protocol, was not computed correctly. The
1532 public key of the responder was not added to the computation
1533 even though it is mandatory. Affected file lib/silcske/silcske.c.
1534 This unfortunately causes incompatibilities with older
1535 clients and servers.
1537 * Added WIN32 specific network init and uninit functions:
1538 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1539 the Winsock2. Affected file lib/silcutil/silcnet.h and
1540 lib/silcutil/win32/silcwin32net.c.
1542 * Set the socket always to nonblocking mode on WIN32 after
1543 reading data or writing data. Affected file is
1544 lib/silcutil/win32/silcwin32sockconn.c.
1546 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Fixed various compilation problems under WIN32. Affected
1549 files lib/silcutil/win32/silcwin32thread.c and
1550 lib/silcutil/win32/silcwin32schedule.c.
1552 * Removed all _internal.h #includes from public header
1553 files. Internal headers must never be included from
1556 Removed also the lib/silcske/payload_internal.h file.
1558 * All include files that may be needed (public and some others
1559 included by the public headers) by application developers are
1560 now copied to the ./includes directory. It does not copy any
1561 internal headers. Affected file Makefile.defines.pre and all
1562 Makefile.am's under lib/ and subdirs.
1564 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Do not change the ~/.silc directory's permissions automatically.
1567 Affected file irssi/src/silc/core/clientutil.c.
1569 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Do not cancel the protocol in silc_server_close_connection
1572 it might cause recursion. Now cancelled in the function
1573 silc_server_free_sock_user_data. Affected file silcd/server.c.
1575 * Fixed the silc_server_remove_clients_by_server to regenerate
1576 the channel keys correctly finally. Added also new function
1577 silc_server_remove_clients_channels to actually do it.
1578 Affected file silcd/server.c.
1580 * Fixed the silc_server_new_channel to not crash by giving
1581 wrong router to the new channel. Affected file is
1582 silcd/packet_receive.c.
1584 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1587 which is given as argument to the silc_client_alloc now.
1588 It can be used to configure the client and set various parameters
1589 that affect the function of the client.
1591 * The USERS command in server did not check whether the channel
1592 is private or secret. Affected file silcd/command.c.
1594 * Added new argument to the USERS command in protocol specification.
1595 The USERS command now can take the channel name as argument
1596 as well. Added support for this in client and server and
1597 updated the protocol specs.
1599 * Completed the GETKEY command in client. It can be now used
1600 to fetch also servers public key not only some clients.
1601 Affected files lib/silcclient/command[_reply].c.
1603 * Added silc_client_get_server to return server entry by the
1604 server name. Affected files lib/silcclient/silcapi.h and
1607 * Redefined the IDENTIFY command in protocol specification to be
1608 more generic. It now can be used to query information about
1609 any entity in the SILC Network, including clients, servers and
1610 channels. The query may be based either the entity's name
1611 or the ID. Added support for this in both client and server.
1613 Affected files silcd/command.c and lib/silcclient/command.c
1614 and command_reply.c.
1616 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1617 the _from_client and _from_server functions. Affected file
1620 * Added silc_client_get_channel_by_id_resolve to the file
1621 lib/silcclient/silcapi.h to resolve channel information by
1622 its ID. Added also silc_client_get_channel_by_id that
1623 does not resolve it from the server.
1625 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Added SilcServerEntry context into the client library
1628 to represent one server. The INFO command now allocates
1629 these to save the resolved server info. For now on the
1630 client library will also keep information about servers,
1631 connected and resolved with INFO.
1633 The INFO command now allocates the SilcServerEntry context
1634 and saves the server info there. The COMMAND_REPLY in
1635 the INFO now returns the parameters to application in
1636 same order as defined in the protocol specification.
1638 The entries are cached in the client->server_cache.
1640 * The INFO command is now issued after received the Client ID
1641 from the server. Affected file lib/silcclient/client.c.
1643 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1644 to the application as the mode changer might be server.
1645 It is guaranteed that NULL is not returned anymore to the
1646 application. Affected file lib/silcclient/client_notify.c.
1648 The ID Type is now also passed to the application so that
1649 it can check whether the returned entry is SilcClientEntry
1652 Added new function silc_client_get_server_by_id to return
1653 the server entry by ID. Affected files are the
1654 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1656 * Do not create the channel in the Irssi SILC Client when issuing
1657 the JOIN command but when received the sucessful JOIN command
1658 reply. Otherwise the channel might get created even though we
1659 could not join it. The Affected file is
1660 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1662 * Fixed a channel joining bug in router. The router must also
1663 check the channel modes, invite and ban lists etc. when serving
1664 the JOIN command sent by normal server. Affected file is
1665 silcd/command.c. The router now resolves the client's
1666 information from the server who sent the JOIN command if it
1667 does not know it, and processes the JOIN command only after
1670 * Changed the SilcCommandCb to take new argument; void *context2.
1671 Affected file lib/silccore/silccommand.h
1673 The second argument in the command callbacks in the server now
1674 includes the SilcServerCommandReplyContext if the command was
1675 called as pending command callback from the command reply.
1676 Otherwise it is NULL. When called as pending the status of the
1677 command reply will be checked and if it was erronous the
1678 error will be sent to the original sender of the command.
1679 This way the client always receives the error messages even
1680 though the server was actually the one who received the error
1681 when it resent the command to router, for example. Affected
1682 files silcd/command[_reply].[ch].
1684 * Fixed sending WHOWAS command's error message to client if
1685 the requested client could not be found. It was missing.
1688 * Changed the CMODE and CUMODE commands reply arguments in the
1689 protocol specification. The Channel ID is now sent in both
1690 of the commands to identify the channel. Implemented this
1691 new feature to the client and server. Affected files
1692 lib/silcclient/command_reply.c and silcd/command.c.
1694 * Made better checks for invite and ban lists in the JOIN
1695 command in server. Affected file silcd/command.c.
1697 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * The server now performs the incoming host IP/DNS lookup
1700 using the silc_socket_host_lookup and thus does not block
1701 the server anymore. Affected file silcd/server.c.
1703 * Completed the multi-thread support for SILC Scheduler in
1704 the lib/silcutil/silcschedule.c.
1706 * Fixed the configure.in.pre to detect the pthread correctly
1709 * Fixed a deadlock in silc_task_queue_wakeup in the file
1710 lib/silcutil/silctask.c.
1712 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Added new function silc_schedule_wakeup that is used in
1715 multi-threaded environment to wakeup the main thread's
1716 schduler. It needs to be used when a thread adds a new task
1717 or removes a task from task queues. After waking up, the
1718 scheduler will detect the task queue changes. If threads
1719 support is not compiled in this function has no effect.
1720 Implemented the wakeup mechanism to both Unix and WIN32
1721 systems. Affected files are lib/silcutil/silcschedule.[ch],
1722 lib/silcutil/unix/silcunixschedule.c and the
1723 lib/silcutil/win32/silcwin32schedule.c.
1725 * Added new function silc_task_queue_wakeup to wakeup the
1726 scheduler by the specified task queue. Affected file
1727 lib/silcutil/silctask.[ch].
1729 * The silc_socket_host_lookup_start now wakes up the scheduler
1730 after adding the timeout task. Affected file is
1731 lib/silcutil/silcsockconn.c.
1733 * The silc_socket_host_lookup is synchronous now if the threads
1734 support is not compiled in. However, the callback is still
1735 called asyncronously through the scheduler, anyway. Affected
1736 file lib/silcutil/silcsockconn.c.
1738 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1740 * Added new function silc_socket_host_lookup to perform
1741 asynchronous IP and FQDN lookups for the socket connection.
1742 Affected files lib/silcutil/silcsockconn.[ch].
1744 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1747 that may or may not compile the mutex support in.
1749 Changed the silc_mutex_alloc interface. It allocates the
1750 mutex now to the sent pointer and returns TRUE or FALSE.
1752 Affected file lib/silcutil/silcmutex.h.
1754 * Wrote the SILC Task Queue interface to support multi-threads.
1755 Affected file lib/silcutil/silctask.[ch].
1757 * Wrote the SILC Scheduler to support multi-threads. Affected
1758 file lib/silcutil/silcschedule.c.
1760 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1763 in lib/silcutil/win32/.
1765 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Defined SILC Mutex API and SILC Thread API and implemented
1768 them for Unix. Affected files are
1769 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1770 lib/silcutil/unix/silcunixmutex.c and
1771 lib/silcutil/unix/silcunixthread.c.
1773 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1775 * Fixed the silc_server_remove_clients_by_server's channel
1776 key re-generation. The hash table handling was incorrect
1777 and would not work with many channels. Affected file is
1780 * Fixed some memory leaks around the server code.
1782 * Rewrote the silc_server_get_users_on_channel to support IPv6
1783 based Client ID's. Affected file silcd/server.c.
1785 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1786 specification. However, a separate document must be written
1787 to define the detailed signing procedure and the payload
1788 associated with the flag. Defined the flag to the
1789 lib/silccore/silcchannel.h as well.
1791 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Changed the dynamic tables to static size tables in the
1794 lib/silccrypt/silchmac.c.
1796 * Removed GCC dependencies from the code. A patch by cras.
1798 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Do not show the error "Error receiving packet bla bla"
1801 in server if it really was not an error (-2 means that reading
1802 is pending). Affected file silcd/server.c.
1804 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Fixed a possible crash in silc_server_remove_clients_by_server
1807 in silcd/server.c. Fixed there also some memory leaks.
1809 * Fixed the silc_idlist_replace_client_id. It could replace
1810 wrong key in the hash table. Affected file silcd/idlist.c.
1812 * Do not check whether there are global users on the channel
1813 if the channel->global_users is FALSE. Affected functions
1814 silc_server_remove_from_one_channel and
1815 silc_server_remove_from_channels in silcd/server.c. Also,
1816 do not check if the removed client is local as we can be
1817 sure that global client was not removed from the channel
1818 and checking for global users is not needed.
1820 * The silc_server_remove_clients_by_server now re-generates
1821 the channel keys correctly for those channels that had
1822 clients removed from them. Affected file silcd/server.c.
1824 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Found the reason of random crashes in the server. We weren't
1827 ignoring the SIGPIPE signal (which can be sent in write())
1828 and it crashed the server. Affected file silcd/silcd.c.
1830 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Assure that sock->user_data is not NULL in the function
1833 silc_server_packet_send in silcd/packet_send.c.
1835 * Disconnect the remote connection if it could not be added
1836 to any ID lists in the server. The affected file is
1839 * Check in silc_server_packet_send[_real/dest] that the
1840 socket is not disconnecting and ignore the data if it is.
1841 Affected file silcd/packet_send.c.
1843 * Define inline to __inline on native WIN32 compilation.
1844 Affected file includes/silcwin32.h.
1846 * Added some explicit type casts for inline code since MSVC
1847 require them. Affected files lib/silcutil/silcbuffer.h,
1848 lib/trq/silcdlist.h and lib/trq/silclist.h.
1850 * Print warning in log files from now on if the packet
1851 decryption fails. Affected file silcd/server.c.
1853 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * Changed the `say' client operation's interface to accept
1856 new `type' argument to indicate the type of the message sent
1857 by the library. The application may filter the library's
1858 messages according the type. The affected file is the
1859 lib/silcclient/silcapi.h.
1861 * Added two new functions to lib/silcclient/silcapi.h:
1862 silc_client_del_client and silc_client_del_client_by_id.
1863 Affected file lib/silcclient/idlist.c.
1865 * Moved the clientincludes.h from includes/ to silc/ and
1866 serverincludes.h from includes/ to silcd/.
1868 * The modes for the CMODE and CUMODE are now passed as
1869 uint32 for application with COMMAND_REPLY. The affected
1870 file is lib/silcclient/command_reply.c.
1872 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * /WHOIS without arguments shows client's own information.
1875 Affected file lib/silcclient/command.c.
1877 * Changed PING to not accept any arguments. The specs
1878 says that client can ping only the connected server so
1879 requiring an argument is not needed. Affected file is
1880 lib/silcclient/command.c.
1882 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Fixed a fatal bug in private message sending and reception
1885 encryption and decryption when using private message keys.
1886 The implementation was incorrect and did not follow the
1887 specification. It causd that some of the message were
1888 lost since it did not use the sending and receiving keys
1889 as the protocol suggests. This has been fixed and will cause
1890 incompatibilities with older clients when sending private
1891 message encrypted with private message keys. Affected files
1892 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1893 and various other in Irssi SILC Client.
1895 Added `responder' boolean argument to the functions
1896 silc_client_add_private_message_key[_ske] to indicate when
1897 the key is added as responder or initiator of the key
1900 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * Removed the silc_ske_check_version function and created
1903 a SilcSKECheckVersion callback. Added also a function
1904 silc_ske_set_callbacks that is now used to set all SKE
1905 callbacks. The callback functions are not given to
1906 the SKE functions anymore, but this function is used to
1909 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1911 * Added `silc_version' argument to the silc_client_alloc
1912 to define the version of the application for the library.
1913 The library will use the version string to compare it
1914 against the remote host's (usually a server) version
1915 string. Affected file lib/silcclient/silcapi.h
1917 * Added the KE protocol context to Key Agreement context
1918 in client library so that we can abort the SKE if it
1919 is in process when we get timeout. Affected file is
1920 lib/silcclient/client_keyagr.c.
1922 * Do not resolve the client ID forever if it returns in the
1923 first time that such client does not exist. This was done
1924 for example with private message. Affected file is
1925 lib/silcclient/client_prvmsg.c.
1927 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Do not add regex.h for WIN32. The affected file
1930 includes/silcincludes.h.
1932 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1933 not work yet 100%. It generates the DLL's automatically
1934 when compiling with --with-win32 under cygwin.
1936 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * lib/contrib/regex.c is not compiled on WIN32.
1940 * Added silc_net_get_socket_opt function to the
1941 lib/silcutil/silcnet.h.
1943 * Added includes/silcwin32.h for WIN32 specific includes
1946 * Do not use ptime structure or any of the posix process
1947 functions on WIN32 in lib/silccrypt/silrng.c.
1949 * Added silc_gettimeofday to provide generic function
1950 for struct timeval on all platforms. Added the function
1951 to lib/silcutil/silcutil.h.
1953 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1956 library as they clearly belong there. As a plus side we
1957 can make the actual socket connection routines platform
1960 Added also new generic function silc_socket_read and
1961 silc_socket_write (that used to be silc_packet_[read/write].
1962 The implementation of these are platform specific.
1964 * Added WIN32 specific routines of silc_socket_[read/write]
1965 to lib/silcutil/win32/silcwin32sockconn.c.
1967 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Added preliminary support for native WIN32 compilation under
1970 cygwin (using the -mno-cygwin option for GCC) to the
1971 ./configure.in.pre. The --with-win32 now prepares the
1972 compilation for native WIN32.
1974 * Rewrote the SILC Scheduler interface in the file
1975 lib/silcutil/silcschedule.h. The scheduler is now context
1976 based and does not have anymore any global static scheduler.
1977 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1978 and created lib/silcutil/win32 directory for WIN32 based
1981 * Added Unix specific network routines to the
1982 lib/silcutil/unix/silcunixnet.c and the old
1983 lib/silcutil/silcnet.c includes now only generic routines.
1985 Added WIN32 specific network routines to the
1986 lib/silcutil/win32/silcwin32net.c.
1988 * Added Unix specific utility functions from the
1989 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1991 * Added WIN32 SILC Scheduler to the file
1992 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1995 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Do not handle JOIN notify in the server if the target client
1998 is not registered (idata->registered == FALSE). The affected
1999 file is silcd/packet_receive.c.
2001 * Update the nickrec->founder in event_cumode in the Irssi SILC
2002 client. Affected file irssi/src/silc/core/silc-channels.c.
2004 * Fixed the CUMODE_CHANGE notify handling in the server when
2005 server and router are announcing their clients on channels.
2006 Now the mode changes are saved and notified correctly. The
2007 affected file is /silcd/packet_receive.c.
2009 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2010 They really did not replace the cache entry in the ID Cache.
2011 Now they do that. Affected file silcd/idlist.c.
2013 * Fixed the KICK notify handling in the Irssi SILC client to
2014 update the channel records so that the kicked client does not
2015 appear to be on the channel. The affected file is
2016 irssi/src/silc/core/silc-channels.c.
2018 * Always update the conn->current_channel when executing command
2019 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2021 * Fixed the KILL notify handling in Irssi SILC client to remove
2022 the killed client on all channels.
2024 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Fixed the silc_parse_command_line to remove extra spaces
2027 from the start and end of the arguments. Affected file is
2028 lib/silcutil/silcutil.c.
2030 * Cancel and free any active protocol in the function
2031 silc_server_close_connection. Affected file silcd/server.c.
2033 * Cancel and free any active protocol in the function
2034 silc_client_close_connction. Affected file is
2035 lib/silcclient/client.c.
2037 * Do not execute the KILL command for clients that are in
2038 history (ie. they are not in the network). Affected file is
2041 * Fixed KILL notify handling, client does not crash anymore.
2042 Affected file irssi/src/silc/core/silc-channels.c.
2044 * Reduced the default packet buffer size from 2048 to 1024 in
2045 lib/silccore/silcpacket.c.
2047 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2048 counter to the SKE context that is incresed when the SKE library
2049 performs async operation outside the library. If the outside
2050 process frees the SKE context and FREED status will be set
2051 and the library will detect after the sync operation that the
2052 libary is freed. The affected files are
2053 lib/silcske/silcske[_status].[ch].
2055 * Resolve the client entry information in the function
2056 silc_client_channel_message to assure that NULL pointer is not
2057 passed as client entry to the application. */
2059 * Fixed the task timeout calculation to assure that there is
2060 never negative timeouts. The affected file is
2061 lib/silcutil/silcschedule.c.
2063 * Fixed the channel user mode notification sending in server.
2064 It was sent point-to-point to the router (or to server by router)
2065 but it needs to be destined to a channel. The routines now
2066 supports sending the channel user mode notifys to the channels
2067 when announcing clients and channels. Affected files are
2068 silcd/server.c and silcd/packet_receive.c.
2070 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2071 It did not actually replace the old channel entry in the cache.
2072 Affected file lib/silcclient/client_notify.c.
2074 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Fixed a possible crash in silc_packet_send_prepare. It now
2077 assures always that there is enough space in the buffer and
2078 at the tail area of the buffer (for MAC).
2080 Fixed the inbound buffer reallocation in silc_packet_read.
2081 It was old code and did not handle the reallocation correctly.
2084 The affected file is lib/silccore/silcpacket.c.
2086 * Fixed buffer overflow in silc_parse_nickname in the file
2087 lib/silcutil/silcutil.c.
2089 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * make install generates new server keys only if there is not
2094 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2097 Added check that if the NOREPLY is set then we will not send
2098 the away message. This avoids infinite loop of away messages
2099 if both clients are away. The affected file is
2100 lib/silcclient/client_prvmsg.c.
2102 * Fixed client crash if /NICK was given without arguments.
2103 Affected file lib/silcclient/command.c.
2105 * Server does not send the invite list in INVITE command back
2106 to the client if the list was not altered. Added this notion
2107 to the protocol spec as well. Affected file silcd/command.c.
2109 Fixed possible crash in INVITE command by checking the
2110 value of silc_server_get_client_route command.
2112 * Fixed the INVITE notify type handling. The arguments are now
2113 taken in correct order and client does not crash. The affected
2114 file is irssi/src/silc/core/silc-channels.c.
2116 Removed the "Inviting xxx to channel" message from the
2117 client library away and let the application handle it.
2118 Affected file lib/silcclient/command.c. Added that message
2119 to Irssi SILC client's message formats.
2121 * Fixed CMODE command crash in client. It now checks the
2122 amount of arguments correctly and does not crash. The affected
2123 file is lib/silcclient/command.c.
2125 * Do not create new channel automatically in silc_channels_join
2126 but check whether the channel by that name already exists.
2127 Affected file irssi/silc/core/silc-channels.c.
2129 * Do not send the SERVER_SIGNOFF to router if the disconnected
2130 entity was the router. Affected file silcd/server.c.
2132 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2133 SILC client as it was missing from there.
2135 Added the handling of the KICK notify to the Irssi SILC client
2136 as it was missing. Added "you have been kicked" message to
2137 Irssi SILC client's message modules formats.
2139 Added the handing of the KILL notify to the Irssi SILC client
2140 as it was missing. Added the kill message module formats
2143 The affected file is irssi/src/silc/core/silc-channels.c.
2145 * The router did not save the channel mode the server announced.
2146 Affected file silcd/packet_receive.c.
2148 * Fixed a possible crash in INFO command in server. If the
2149 server did not provide the server info it crashed. Affected
2150 file silcd/command.c.
2152 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Fixed the GETKEY command in the server to check also the
2155 global list. Otherwise the GETKEY would not work correctly
2156 in normal SILC server. Affected file silcd/command.c.
2158 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Fixed GETKEY crash, it crashed if the command did not succseed.
2162 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2165 is now real and not just an macro interface to GMP.
2167 Removed the entire GMP from the source tree and imported new
2168 NSS MPI library instead. Reason for removing GMP is that it is
2169 extremely large and compiles extremely slow. The NSS MPI
2170 is only a few files and compiles in less than 10 seconds.
2171 The speed is also about the same as GMP. The MPI is imported
2172 to lib/silcmath/mpi.
2174 If the system has GMP installed we will still use the GMP.
2175 If it is not then the NSS MPI will be compiled.
2177 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Merged a long nickname (127 characters long) crash bugfix from
2180 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2182 * Merged a freed memory reference bugfix from Irssi CVS tree.
2183 Affected file irssi/src/core/commands.c.
2185 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Added the server's public key sving and verification to the
2188 server when performing the SKE. This was missing and the
2189 remote server's (or router's) public key was accepted without
2190 checking whether we have it previously or trust it at all.
2191 Affected file silcd/protocol.c.
2193 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2195 * Check in the silc_server_timeout_remote if protocol is active
2196 and make sure that the protocol's final callback is called so
2197 that all memory if freed. Affected file silcd/server.c.
2199 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * silc_server_whois_send_reply crashed the server if the nickname
2202 was 127 characters long. Affected file silcd/command.c.
2204 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Added sanity check to the silc_server_new_client. If the hostname
2207 is provided inside username then check that the provided hostname
2208 really is the same as the resolved one. If the hostname was not
2209 resolved then check it from the public key. Affected file is
2210 silcd/packet_receive.c.
2212 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2213 if the server disconnected us and the connection is not valid
2214 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2216 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2217 the library to the lib/silcutil/silcutil.[ch].
2219 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Close log file after open. Affected file
2222 lib/silcutil/silclog.c.
2224 * Check whether sock == NULL in silc_client_send_packet and return
2225 if it is. Affected file lib/silcclient/silcclient.c.
2227 * Check rec->entry == NULL in the Irssi SILC Client before
2228 sending the channel message. Affecte file is
2229 irssi/src/silc/core/silc-servers.c.
2231 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Merged a splitted window bugfix from Irssi CVS tree. The
2234 affected file is irssi/src/fe-text/textbuffer-view.c.
2236 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2237 It did not print nickname.
2239 * Improved the distributions system a bit.
2241 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2244 irssi/src/fe-text/gui-window.c.
2246 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2247 to in-active server. The affected file is
2248 irssi/src/silc/core/client_ops.c.
2250 * Resolve the client in USERS command reply if the entry does
2251 not have username resolved. The affected file is
2252 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2253 command to WHOIS command to really resolve stuff. The USERS
2254 is not used any more in any critical section so WHOIS can
2255 be used even though it might be slower than IDENTIFY.
2257 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2260 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2262 * Changed the protocol API a bit more consistent in the
2263 lib/silccore/silcprotocol.[ch].
2265 * Changed the following headers to ROBODoc format:
2267 lib/silccore/silcpayload.h
2268 lib/silccore/silcprotocol.h
2269 lib/silccore/silcsockconn.h
2271 All core library headers are now formatted.
2273 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * Fixed a bug in Irssi SILC client; do not show that you are
2276 server/router operator if you really are not. Affected file is
2277 irssi/src/silc/core/client_ops.c.
2279 * Renamed silc_command_free_payload to silc_command_payload_free.
2280 Affected file lib/silccore/silccommand.h
2282 * Added silcmath.h to include the prototoypes of various routines
2283 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2286 * Changed the following headers to ROBODoc format:
2288 lib/silccore/silcchannel.h
2289 lib/silccore/silccommand.h
2290 lib/silccore/silcid.h
2291 lib/silccore/silcidcache.h
2292 lib/silccore/silcmode.h
2293 lib/silccore/silcnotify.h
2294 lib/silccore/silcpacket.h
2295 lib/silcmath/silcmath.h
2297 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Added checking to the server code not to start the server if
2300 ciphers and stuff are not configured properly. Affected files
2301 silcd/serverconfig.[h] and silcd/server.c.
2303 * Changed the layout of the header files of the public interfaces
2304 in the SILC libraries. The new layout supports ROBODoc
2305 documentation tool (and some others) so that it is easy to create
2306 a library reference manual. All the other headers and source
2307 code must still follow the CodingStyle document. Also source
2308 code must not include these ROBODoc stuffs, only the headers.
2309 Furthermore, all public interface headers must now be named
2310 by using `silc' prefix, example: silcapi.h, silccipher.h.
2311 Some files were renamed due to this. All the other headers
2312 must not be used as public interfaces. I will update the
2313 CodingStyle document later. Changed following headers, so far:
2315 lib/silcclient/silcapi.h
2316 lib/silccore/silcauth.h
2317 lib/silccore/silcprivate.h
2318 lib/silccrypt/silcdh.h
2320 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Removed silc_client_packet_send_flush from the client library
2325 as it is not needed. Affected file lib/silcclient/client.[ch].
2327 * Added printing of message of unresolved authentication method
2328 to the Irssi SILC client. Added it to the module formats.
2329 Removed the same message from the client library.
2331 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Added new distribution feature, DISTLABEL. Every distribution
2334 can define own preprocessor label that can be used in the
2335 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2336 file distributions, acconfig.h.pre and prepare.
2338 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added Makefile.defines_int to include the actual definitions
2341 for Makefile.defines.in. Tested the new distribution system,
2342 created distributions and tested installation.
2344 * Added AWAY message printing to the Irssi SILC client. Added
2345 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2347 * Added SCONNECT command to call the SILC's CONNECT command.
2348 Cannot use CONNECT directly since Irssi uses that internally.
2349 Affected file irssi/src/silc/core/silc-servers.c.
2351 Added ACTION local command. It is same as ME command but takes
2352 the channel as mandatory argument.
2354 Rewrote some of the Irssi's help files to suite for SILC
2357 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Added Makefile.defines[.in] that should for now on be included
2360 in all Makefile.am file in the source tree. That file includes
2361 all common compilation definitions for SILC source tree.
2363 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Minor changes to the ./prepare script to change the package
2366 name according the distribution name to the configure.in.
2368 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Created new distribution system. Added file `distributions'
2371 that defines all the distributions that can be created out of
2372 the SILC source tree. The ./prepare script now reads that
2373 file to determine how to prepare the distributions. The
2374 first argument to the ./prepare is the name of the distribution
2375 and second is the version of the distribution. If given
2376 without arguments it creates the default (toolkit) distribution
2377 with the default version (defined in ./prepare).
2379 All Makefile.am files that are subject to the distributions
2380 are now named as Makefile.am.pre. These are ./Makefile.am
2381 and lib/Makefile.am. Others may be changed later.
2383 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * Added invite list, ban list, some key management and connection
2386 error message printing to module formats in the Irssi SILC client.
2388 * Added new silc_client_set_away_message to set the away message
2389 that is back to the person who sent private message. The
2390 affected file lib/silcclient/silcapi.h and the
2391 lib/silcclient/client_prvmsg.c.
2393 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Fixed the private message sending in the Irssi SILC client,
2396 added local command KEY to the Irssi SILC client.
2398 Added key management and key agreement message formats to the
2399 irssi/src/fe-common/silc/module-formats.[ch].
2401 Added USERS (alias WHO) printing, server/router operator
2402 indication and LIST command printing to the module formats.
2404 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Fixed channel joining notify handling, cumode notify handling
2407 from Irssi SILC client.
2409 * Added SILC specific module-formats to the Irssi SILC client so
2410 that SILC specific message hilighting, colors etc is possible.
2411 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2413 Added channel mode, channel user mode, actions, notices,
2414 whois and whowas printing to the the module-formats.c.
2416 * Fixed a bug in channel deletion in the server. The channel
2417 is not left to the cache even if the channel founder auth mode
2418 is set when there are no users anymore on the channel. Affected
2419 file silcd/server.c.
2421 * The silc_net_localhost now resolves the entire hostname including
2422 the domain name. Affected file lib/silcutil/silcnet.c.
2424 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Changed the ask_passphrase client operation to be ascynchronous.
2427 It has now a completion callback and a context that the
2428 application must call after it has got the passphrase from
2429 the user. Affected files lib/silcclient/silcapi.h,
2430 lib/silcclient/protocol.c, lib/silcclient/command.c and
2433 Added SilcAskPassphrase callback that the application calls
2434 to deliver the passphrase to the library.
2436 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2437 The public key verification and especially a certificate
2438 verification is asynchronous procedure.
2440 Added new SILC_SKE_STATUS_PENDING status to indicate the
2441 request is pending and a callback will be called to finalize
2444 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2445 indicate that remote end did not send its public key (or
2446 certificate), even though we require it. Added check for this
2447 condition in the SKE. This was a security bug, now fixed.
2449 Defined new SilcSKEVerifyCbCompletion callback that is called
2450 when the verification process is completed.
2452 The affected files lib/silcske/silcske_status.h and
2453 lib/silcske/silcske.[ch].
2455 * Changed the verify_public_key client operation to be async
2456 as well. Defined SilcVerifyPublicKey callback that is used to
2457 indicate the success of the public key verification process.
2459 Changed the server and client to use the new async client
2462 * Changed the Irssi SILC client's internal scheduler to be called
2463 twice as many times as it used to be. As a result the client
2464 should be a bit faster now. Affected file is
2465 irssi/src/silc/core/silc-core.c.
2467 * Added support to Irssi SILC client of asynchronous public key
2468 verification and passphrase inquiry. Affected file is
2469 irssi/src/silc/core/silc-core.c.
2471 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Do not say "You have left channel %s" in client library.
2474 Moved it to the application. Affected files are
2475 lib/silcclient/command.c and silc/client_ops.c.
2477 * Fixed silc_client_get_clients. Command context was not
2478 duplicated and was freed memory in the callback. Affected
2479 file lib/silcclient/idlist.c.
2481 * Do not say "you are now talking..." on JOIN command in the
2482 client library. The appliation must handle it.
2484 * Do not say ".. changed topic to" in command reply in the
2485 client libary. The application must handle it.
2487 * Fixed TOPIC command sending in the client library.
2489 * Fixed a memory leak in silc_client_command_free in the file
2490 lib/silcclient/command.c.
2492 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Imported a modified version of Irssi client to the source tree.
2495 The Irssi will be used to create a new client called
2496 Irssi SILC. Imported to irssi/.
2498 Added silc_core_init_finish function to the Irssi. Affected
2499 file irssi/configure.in.
2501 A lot changes in the Makefile.ams around the irssi tree.
2503 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Do not rehash if the new size is same as the old size of the
2506 hash table, in the silc_hash_table_rehash*. The affected file
2507 lib/silcutil/silchashtable.c.
2509 * Replaced hash_table_del_by_context calls from the server
2510 (when channel->user_list and client->channels) to the
2511 hash_table_del as it is sufficient and faster.
2513 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Added silc_hash_table_list, silc_hash_table_get and the
2516 SilcHashTableList structure to provide an alternative way to
2517 traverse the hash table. The affected files are
2518 lib/silcutil/silchashtable.[ch].
2520 * Changed the server's idlist routines to use the hash table
2521 routines to optimize the code.
2523 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Replaced the client entry's `channel' list and channel entry's
2526 `user_list' list to hash tables for optimized lookup. Changed
2527 the code to use the hash table interface around the code.
2528 Affected file lib/silcd/idlist.[ch].
2530 * Added `auto_rehash' boolean argument to the function
2531 silc_hash_table_alloc to indicate whether the hash table should
2532 auto-rehash when it thinks is appropriate time. It will
2533 increase the hash table size if the there is twice as much
2534 entries in the table than the size of the table, and will
2535 decrease the size if there are twice as less entries than
2536 the size of the table.
2538 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2542 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * silc_idcache_purge_by_context deletes the entry now by context
2545 as it is supposed to do. Affected file lib/silccore/idcache.c.
2547 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2548 client is not anymore valid (WHOWAS givens the info) and not
2549 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2551 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2553 * Removed the `data' and `data_len' arguments from the ID Cache
2554 interfaces and added `name' argument. ID Cache does not handle
2555 anymore the binary data only a names associated with given ID.
2557 * When hashing a Client ID with silc_hash_id the entire ID is
2558 not hashed anymore, instead only the hash of the Client ID is
2559 hashed. This way we can access the Client ID from the cache
2560 with Client ID but with the hash of the ID (which is a hash of
2561 the nickname) as well without any difference in performance.
2563 Added also silc_idcache_find_by_id_one_ext to do one on one
2564 searching when we have the actual ID. Added also function
2565 silc_hash_client_id_compare. The affected files are
2566 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2568 * When hashing the name associated with a ID it is always done
2569 in lowercase. This way we can access the cache without worrying
2570 about case-sensitivity, even though, for example nicknames are
2573 * Fixed a bug in server with channel message sending. It put
2574 wrong ID type as destination ID. The affected file
2575 silcd/packet_send.c.
2577 * silc_idcache_del_by_context now deletes from all hash tables
2578 by context. Affected file lib/silccore/idcache.c.
2580 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Changed the client library to use the new ID Cache interface.
2583 Changes around the source tree.
2585 * Added silc_hash_table_rehash_ext to rehash with specific
2586 hash function. Affected file lib/silcutil/silchashtable.[ch].
2588 * Added silc_hash_string_compare to compare two strings in the
2589 hash table. Affected file lib/silcutil/silcutil.[ch].
2591 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added new function silc_idcache_del_by_context into the
2594 lib/silccore/idcache.[ch].
2596 * Changed the server's ID list routines to use the new ID Cache
2597 interface. Changes around the source tree.
2599 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added silc_hash_table_del[_by_context]_ext functions in to the
2602 lib/silcutil/silchashtable.[ch].
2604 Removed silc_hash_table_find_all* routines and added new
2605 silc_hash_table_find_foreach to replace them.
2607 Added silc_hash_table_replace_ext function as extended
2608 replacing function. Separated the simple hash table interface
2609 from the extended hash table interface in the file
2610 lib/silcutil/silchashtable.h.
2612 * Fixed minor bugs and changed it to use some of the new
2613 hash table functions in lib/silccore/idcache.c
2615 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Added new function silc_hash_table_find_all to return all keys
2618 in the hash table by the specified key. As the hash table is
2619 collision resistant it also makes it possible to have several
2620 duplicate keys in the hash table. This function may be used to
2621 find all of the keys from the hash.
2623 Added user_context arguments to the SilcHashFunction,
2624 SilcHashCompare and SilcHashDestructor to deliver user specified
2627 Added new fuctions silc_hash_table_find[_all]_ext to do
2628 extended lookup with specified hash and compare functions and
2629 specified user contexts.
2631 Added new function silc_hash_table_add_ext to add the key
2632 with specified hash function and user context.
2634 Added new function silc_hash_table_foreach to traverse all
2635 entrys in the hash table. Added SilcHashForeach callback
2638 Added new function silc_hash_table_del_by_context to delete
2639 the entry only if the context associated with the key matches.
2641 Affected files are lib/silcutil/silchashtable.[ch].
2643 * Removed silc_hash_[server/client/channel]_id and added just
2644 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2645 silc_hash_id_compare to compare two ID's using as the hash table
2646 comparison function. Added also silc_hash_data to hash
2647 binary data and silc_hash_data_compare to compare it.
2649 * Removed silc_idlist_find_client_by_hash as it is not needed
2650 anymore. Affected file silcd/idlist.[ch].
2652 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2653 to use internally the SilcHashTable. The new ID Cache is a lot
2654 faster than the old one. Some of the ID Cache interface was also
2655 rewritten and obsolete and stupid functions were removed.
2657 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Added entry_count field to the SilcHashTable to keep the number
2660 of the entries in the table. Implemented the function
2661 silc_hash_table_rehash. Added new function
2662 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2664 Fixed a minor bug in silc_hash_table_free.
2666 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2667 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2668 into the lib/silcutil/silcutil.[ch].
2670 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Implemented a collision resistant hash table into the
2673 lib/silcutil/silchashtable[ch]. See the header and the source
2674 for the SilcHashTable API.
2676 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Merged dotconf version 1.0.2 into lib/dotconf.
2680 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Do not compile anything in lib/silcsim/* if the SIM support
2683 is not enabled. The tree should now compile without problems
2686 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Compiled the SILC under cygwin. Compiled and tested briefly
2689 without problems. More tests needed. The SIMs didn't compile
2692 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2694 * Fixed possible crash in silc_get_username in the
2695 lib/silcutil/silcutil.c.
2697 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Fixed a va_arg in silc/client_ops.c.
2701 * Oops, RC5 routines were named AES and caused some problems
2702 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2704 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Added new SilcIDIP structure into the lib/silccore/id.h and
2707 replaced the old `ip' fields from all SILC ID's to that type.
2708 This is a step towards IPv6 support.
2710 The silc_id_get_len takes now the ID as an extra argument.
2711 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2712 both IPv4 and IPv6 based ID's.
2714 The affected files are lib/silccore/id.[ch] and other files
2715 around the tree using these routines.
2717 * Removed the ID length arguments in server from various
2718 silc_server_send_notify_* routines -> they are not needed
2721 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2723 * Fixed memory leak in silc_encode_pem_file in the file
2724 lib/silcutil/silcutil.c.
2726 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Check minor version as well in the SKE. Affected files are
2729 silcd/protocol.c and lib/silcclient/protocol.c.
2731 * Added --identifier option to the server so that an identifier
2732 can be when creating the public key for the server. Affected
2733 file is silcd/silcd.c.
2735 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2736 lib/silccrypt/silcpkcs.c.
2738 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Register default ciphers and stuff when using -C option with
2741 the server. Affected file sildc/silcd.c.
2743 * Put back the servers public key filename format, it is better
2744 than the new one. For now, the client keys are saved with the
2745 new filename format. The affected file silc/client_ops.c.
2747 * Implemented the Cipher API for the rest of the ciphers that
2748 did not implement it or implemented it the wrong way.
2750 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Register default ciphers and stuff when using the -S option
2753 in the client. Affected file silc/silc.c. Same also when
2754 creating new key pair with -C option.
2756 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Fixed the silc_verify_public_key client operation function to
2759 save the public keys differently. The fingerprint is now
2760 used as filename and not the hostname. This way also the
2761 client keys are saved uniquely and not with hostnames. The
2762 affected file is silc/client_ops.c.
2764 * Trimmed the silc_hash_fingerprint function to remove extra
2765 whitespaces from the end of the fingerprint. The affected
2766 file is lib/silccrypt/silchash.c.
2770 * Added silc_cipher_register_default function to register all
2771 default ciphers. It can be used when configuration files
2772 does not exist and the application does not want any specific
2773 ciphers in any specific order.
2775 The SilcDList is now used as silc_cipher_list dynamically
2776 allocated cipher list. Removed the static list all together
2777 and now all ciphers must be allocated to the dynamic list.
2778 The silc_cipher_alloc routine was changed to check only the
2781 All silc_cipher_* routines that used to return int returns
2784 The affected files lib/silccrypt/silccrypt.[ch].
2786 * The same thing was done to silc_hash_* as for silc_cipher_*
2787 routines. Affected files lib/silccrypt/silchash.[ch].
2789 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2790 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2791 Added also silc_pkcs_[un]register[_default] functions.
2792 Removed the data_context from the PKCS API.
2794 * Added silc_hmac_register_default function to register default
2795 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2796 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2797 to unregister all hmacs at once.
2799 * Register the default ciphers, hash functions, PKCSs and HMACs
2800 if client's configuration file does not exist. The affected
2803 * The client did not load the hash functions from the SIM
2804 modules at all. Added support for this. Affected file is
2805 silc/clientconfig.c.
2807 * When decoding public key with silc_pkcs_public_key_decode, check
2808 the supported algorithm only if PKCS are registered. Affected
2809 file lib/silccrypt/silcpkcs.c. The same was done with the
2810 silc_pkcs_private_key_decode.
2812 * Fixed the SILC List routines to keep the list always in order.
2813 It used to change the list's order when traversing the list but
2814 not it preserves the order. Affected file lib/trq/silclist.h.
2816 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Added the client library to use the SilcSocketConnection's
2819 reference counter (by silc_socket_dup) to prevent the bug that
2820 the socket object may be freed underneath async operation.
2822 * The name resolv library checking fixes in the configure.in.pre.
2825 * Created new version of the protocol drafts for future
2826 development. The -03 drafts are the ones that will be changed
2827 in the trunk now and the -02 will remain as they are.
2829 * Send list of CUMODE notifys to the router when announcing
2830 the channel users to the router. Affected file silcd/server.c.
2831 If the router receiving channel founder CUMODE for a channel
2832 that already has channel founder it will send CUMODE notify
2833 to the sender to remove the channel founder rights from the
2834 announced client. Affected file silcd/packet_receive.c.
2836 * The CUMODE notify may now use Server ID as well as the entity
2837 who changes the mode. Updated protocool specs.
2839 * Updated INSTALL and README files.
2841 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * New web pages in the http://silc.pspt.fi. The pages was
2848 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Implemented the [DenyConnectin] config section in the server.
2851 Added silc_server_config_denied_conn to check whether incoming
2852 connection is denied. Affected file silcd/serverconfig.[ch].
2854 * Do not check the ports when checking the incoming configuration
2855 data if the port is 0, meaning any. Affected file is
2856 silcd/serverconfig.c.
2858 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Fixed buffer overflow in silc_string_compare in the file
2861 lib/silcutil/silcutil.c.
2863 * Fixed double free in silc_server_command_leave in the file
2866 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Fixed the version checking in the server. Affected file is
2871 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Fixed the configuration data fetching when accepting new
2874 connections in the server. Affected file silcd/server.c.
2876 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Added `sender_entry' argument to the function
2879 silc_server_packet_relay_to_channel so that we can check
2880 whether some destination actually belongs to the same route
2881 the sender belongs (ie, we must not resend the packet to the
2882 sender). Affected file silcd/packet_send.[ch].
2884 * Added `servername' field to the SilcClientEntry in the server
2885 to hold the name of the server where client is from. Affected
2886 file is silcd/idlist.h.
2888 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Moved the channel message encrypting in the router betwen
2891 router connections from silc_server_channel_message to the
2892 silc_server_packet_relay_to_channel since we want to check
2893 whether we have anybody channel before encrypting anything.
2894 Affected files silcd/packet_[receive/send].c.
2896 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Fixed the [AdminConnection] server config section to support
2899 multiple entries. Affected file silcd/serverconfig.c.
2901 * Added support into the server to check the validity of the
2902 incoming connection before executing any KE or authentication
2905 * The connection configuration is now saved to the KE and
2906 connection auth protocol contexts and not fetched anymore in
2907 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2909 * The local hosts listenning address and port is also resolved
2910 now when starting the server. We want to have the socket object
2911 to include the real address and port for the listener. Added
2912 new function silc_net_check_local_by_sock into the files
2913 lib/silcutil/silcnet.[ch].
2915 * Fixed a broadcast bug in server -> do not broadcast if we
2918 * Fixed a routing bug. Do not route broadcast packets ever.
2919 Broadcast packets must be processed always and not routed since
2920 they may be destined to some other host than yourself and thus
2921 would get routed without no good reason. Affected file is
2924 * Added function silc_server_config_is_primary_route to check
2925 whether primary router connection has been configured (a router
2926 configuration that we are initiating). If there is not, we
2927 will assume that there is only two routers in the SILC network
2928 and we will use the incoming router connection as our primary
2929 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2931 * Changed the order of the broadcasting. Broadcast _after_ the
2932 packet has been processed not before. Affected file is
2935 * Fixed a [ClientConnection] parsing bug. The port was never
2936 parsed correctly thus resulting to port 0. Affected file
2937 silcd/serverconfig.c.
2939 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2940 argument and did not set the broadcast packet flag. Affected
2941 file silcd/packet_send.c. Fixed same bug in the function
2942 silc_server_send_notify as well.
2944 * If we receive NEW_ID packet for our own ID in the server, ignore
2947 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Removed the nickname from the Private Message Payload.
2952 Updated the code and the protocol specs.
2954 * Updated protocol specs for submitting to the IETF.
2956 * Tweaked the Random Number Generator a bit. Affected file
2957 lib/silccrypt/silcrng.c. Exported a new function
2958 silc_rng_[global]_add_noise which can be used to add more
2961 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Do not parse packets with different timeout when protocol
2964 is active -> may cause problem with rekey. Affected file
2967 * When server receives signoff notify it must not create
2968 new channel key if the client is on any channels since the
2969 sender of the signoff notify will create it.
2971 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added printing of error messages during SKE protocol from the
2974 failure packet sent by server during SKE. Affected file
2977 * Removed the client's failure_callback handling with timeout
2978 and handle it immediately when received.
2980 * The SKE library returned wrong type in SUCCESS and FAILURE
2981 packets. They must be 32 bit MSB not 16 bit MSB.
2983 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2985 * Ok, rewrote the logic of the re-key and now it seems to work.
2986 I tested it on high traffic with frequent re-keys without
2987 problems. Added hmac_receive (and renamed hmac to hmac_send)
2988 in SilcClientConnection in lib/silcclient/client.h and
2989 in SilcIDListData in silcd/idlist.h. Also, removed the
2990 SilcPacketParserContext's cipher and hmac fields as they are
2991 not needed anymore and actually caused some problems when
2992 the ciphers and hmac's changed underneath the packet parser.
2994 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * If re-key protocol is active then process the incoming packets
2997 synchronously since we must assure that icoming packets encrypted
2998 with the old key is processed before the new keys is set to
2999 use. This is true other packets than for REKEY packets.
3000 Affected file silcd/server.c. The same was done to client library
3001 as well, affected file lib/silcclient/client.c.
3003 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Fixed bug in client and server to accept the force send if
3006 the packet is send from silc_[server/client]_packet_process
3007 function. Otherwise the packets are never delivered, oops.
3009 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Disable force sending of packets when REKEY protocol is active.
3012 We must assure that no packet is sent directly when rekey is
3013 performed. All packets must be sent through packet queue.
3014 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3015 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3016 function is silc_[server/client]_packet_send_real to check
3019 * Replaced the SIM paths from example config files to
3020 /usr/local/modules. Also, make install creates now
3021 /usr/local/silc/logs directory to hold all the SILC server
3024 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Made the configure.in.pre work on Solaris. Patch by salo.
3028 * Made all ciphers compatible with non-x86 machines. Defined
3029 CBC mode macros into lib/silccrypt/ciphers_def.h.
3031 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Fixed the make install.
3035 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * When MAC computation fails the silc_packet_decrypt returned 0
3038 even though it was supposed to return -1. Fixed this. The
3039 affected file is lib/silccore/silcpacket.c.
3041 * Do not replace the config files in /etc/silc (in make install)
3042 if they already exist. Affected file ./Makefile.am.
3044 * Do not send re-key packets immediately but through packet queue.
3045 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3047 * Changed silc_net_check_host_by_sock to return FALSE if the
3048 IP/DNS could not be resolved. Though, it returns the IP address
3049 now even if it could not resolve it (but returns also FALSE).
3050 Affected file lib/silcutil/silcnet.[ch].
3052 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Added silc_pkcs_decode_identifier to decode the public key's
3055 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3056 Added also silc_pkcs_free_identifier. Added also new context
3057 SilcPublicKeyIdentifier.
3059 * Added -S option to the silc client. It is used to dump the
3060 contents of the specified public key file.
3062 * Changed the PKCS api to return the public key length when
3063 setting the public key.
3065 * Fixed a fatal bug in the public and private key file loading.
3066 Affected file lib/silccrypt/silcpkcs.c.
3068 * Execute the packet parsing for client with zero (0) timeout
3069 if the protocol is active. Affected file silcd/server.c.
3071 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Made the key generation options to the silcd program. Added
3074 -C option, equivalent to client's option.
3076 * Added new [ServerKeys] config section to the server. It
3077 configures the server's public and private key.
3079 * Defined generic Public Key Payload into the protocol
3080 specification to send specific type of public keys and
3083 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3084 public key or certificate.
3086 * Implemented the GETKEY command to the server and to the
3087 client library and on user interface.
3089 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Made preliminary `make install' work.

3120 SilcClientConnection structure; not needed. Affected file is
3121 lib/silcclient/client.h.
3125 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Do not ask whether user wants to use the negotiated private key
3128 for private messages, just use it. Affected file is
3129 silc/local_command.c.
3131 * Added `send_enc_key' and `enc_key_len' fields to the
3132 SilcIDListData structure since they are needed in the re-key
3133 phase. Affected file is silcd/idlist.[ch].
3135 * Implemented the simple re-key protocol into the server.

3147 the PFS is to be performed in the re-key. Affected file is
3150 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3153 int64 of at least the xintXX size. If void * is less that 4
3154 bytes uint32 * will be used. Defined bool as boolean.
3156 * Changed _ALL_ unsigned long and unsigned int to uint32,
3157 unsgined short to uint16 in the source tree.
3159 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3160 not handle clients that has entry->data.registered == FALSE.
3161 They are not in the network anymore. Affected file is
3164 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Implemented the sending of the SERVER_SIGNOFF notify in the
3167 server. Affected file is silcd/server.c.
3169 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3170 Added also silc_notify_payload_encode_args into the

3178 implemnted the printing of the SERVER_SIGNOFF info to the
3179 application. Affected file silc/client_ops.c.
3181 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3182 if the deleting was successful. Affected file silcd/idlist.[ch].
3184 * Added support for public key authentication in the connection
3185 authentication protocol in the client library. Affected file
3186 lib/silcclient/protocol.c.
3188 * Changed the server's silc_idlist_get_clients_by_* interface
3189 to support already allocated array so that new entries may be
3190 added to pre-allocated array. Affected file silcd/idlist.[ch].
3191 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3192 and command replies.
3194 * All command reply functions in the server now calls the
3195 pending command callback even if error occured. This way the
3196 error will be delivered to the client as well. Affected files
3197 silcd/command.c and silcd/command_reply.c.
3199 * Fixed INFO command to return local server's info if no server
3200 was provided. Affected file lib/silcclient/command.c.
3202 * Removed RESTART command for good. Updated the code and the
3205 * Rewrote parts of the task system. It is a bit simpler now.
3206 Removed unsued task priorities. The affected files are
3207 lib/silcutil/silctask.[ch].
3209 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Moved the USERS printing from the library to the application.
3212 Affected files lib/silcclient/command.c and silc/client_ops.c.
3214 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Added channel key re-key support. The re-key is perfomed
3219 only by the router and is done once in an hour. Added `rekey'
3220 field to the SilcChannelEntry in the server. Affected files
3221 silcd/server.c and silcd/idlist.h.
3223 * Added silc_task_unregister_by_context into the file
3224 lib/silcutil/silctask.[ch].
3226 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Added SILC_UMODE_GONE mode to indicate when the client is not
3229 present in the SILC network. Added also support to the local
3230 command AWAY that will set this mode. Added support of showing
3231 "xxx is gone" in WHOIS command. The USERS command shows the
3232 gone status as well.
3234 * Fixed setting server and router operator privileges in the
3235 server's UMODE command. Affected file silcd/command.c.
3237 * Merged the SKE KE1 and KE2 payloads into one payload. The
3238 new KE payload is equivalent to the old KE2 payload.
3240 Cleaned up the SKE Start Payload parsing. It now uses the
3241 simple buffer unformatting to do the parsing. A lot faster
3244 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3245 to the SKE that is used to indicate whether both of the SKE
3246 parties should perform authentication. By default only the
3247 responder performs authentication. By setting this flag also
3248 the initiator must do authentication. By default it is unset
3249 since in normal SKE case, client to server connection, only
3250 the responder should do authentication. When doing SKE between
3251 two clients both should perform authentication. Updated the
3252 code and the protocol specs.
3254 * A little fix to IDENTIFY command in the server. Search the
3255 client first by hash not nickname. Affected file is
3258 * Fixed the silc_client_close_connection to support closing
3259 the client to client connections wihtout deleting too much
3260 data. Affected file lib/silcclient/client.c.
3262 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3263 are received if protocol used to be active but is not anymore
3264 the application would crash due to NULL pointer dereference.
3265 Affected files silcd/server.c and lib/silcclient/client.c.
3267 * Added `hash' field to the SilcClientConnection to include
3268 the hash function negotiated in the SKE protocol.
3270 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3271 to set the channel founder authentication data. A client can
3272 claim the founder rights later by providing the authentication
3273 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3274 This way the channel founder can regain the channel founder
3275 privileges even it is left the channel. This works only on
3276 local server and the client must be connected to the same
3277 server to be able to regain the founder rights. Updated the
3278 protocol specs accordingly.
3280 Added support to the CMODE command in the client to set the
3281 founder auth data. Read the README to see how to set it.
3283 Added support to the CUMODE command to claim the founder
3284 rights. Read the README to see how to do it.
3286 Added support for the founder authentication to the Channel
3287 Entry in the server. Affected file silcd/idlist.h.
3289 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3290 server's CMODE command. Affected file silcd/command.c.
3292 * Added the following new functions into lib/silccore/silcauth.[ch]:
3293 silc_auth_get_method and silc_auth_get_data.
3295 * The server now saves the remote hosts public key to the
3296 SilcIDListData pointer. Affected file silcd/protocol.c.
3298 * The normal server now does not remove the channel entry from
3299 the cache if the founder authentication data is set. It used
3300 to remove it if the founder was the last one on the channel on
3301 the server and left the channel. The auth data is saved and
3302 if the channel is re-joined later the old entry is used with
3303 the old auth data. Affected files silcd/command_reply.c and
3306 * Removed the `pkcs' field from the SilcIDListData structure
3307 in the server; it is not used. Affected file silcd/idlist.h.
3309 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Fixed packet processing on slow links. Partial packets were
3312 never re-processed because the incoming data buffer was cleared
3313 by the application. Application must not directly clear the
3314 sock->inbuf, the packet processing routines handle it. Fixed
3315 this in client library and in server.
3317 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Fixed the WHOIS and IDENTIFY send reply function to really
3320 check whether to send list or just one entry. Affected file
3323 * Cleaned up the LEAVE command's channel key distribution. The
3324 affected file silcd/command.c.
3326 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3327 can enforce the channel mode as well. In that case the ID
3328 includes the ID of the server. The code now enforces the
3329 mode change if the router have different mode than the server.
3331 * The notify client operation with CMODE_CHANGE notify can now
3332 return NULL client_entry pointer if the CMODE was not changed
3333 by client. Application must check for this.
3335 * Added <Server ID> argument to INFO command to support server
3336 info fetching by Server ID.
3338 * Added silc_server_announce_get_channel_users to get assembled
3339 packets of channel users of the specified channel. Affected
3340 file silcd/server.[ch].
3342 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3343 was freed underneath the ID Cache.
3345 * Re-announce clients when the server received CHANNEL_CHANGE
3346 notify from the router. Affected file silcd/packet_send.c.
3348 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3351 crashed since it did not handle the fact that there is no cipher
3352 called "3" and didn't check the error condition. Now fixed.
3354 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3355 flag. It can be used to send message requests.
3357 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Implemented the RESTART command in the client.
3361 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3362 notice type messages. Added notice printing to the user
3365 * The channel keys are not re-generated if the channel's mode
3366 is PRIVKEY, ie private key on the channel exists. Affected
3367 files silcd/server.c and silcd/command.c.
3369 * Fixed a little bug in channel message delivery when channel
3370 private keys are set in the server. Affected file is
3371 silcd/packet_send.c.
3373 * Changed the setting on channel->on_channel = TRUE from the
3374 silc_client_save_channel_key to the JOIN command reply. The
3375 key payload is not received if the private channel key is set.
3376 Affected file lib/silcclient/command_reply.c and the
3377 lib/silcclient/client_channel.c.
3379 * When the CMODE_CHANGE notify is sent and the channel private
3380 key mode is removed the channel key must be re-generated in
3381 other cells as well. Added this support for the router in the
3382 silcd/packet_receive.c.
3384 * Added new local command NOTICE to send notice message on
3385 channel. Affected file silc/local_command.[ch].
3387 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Added new local command ME to the client. It is used to send
3390 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3391 some action. Affected file silc/local_command.[ch].
3393 * Changed channel_message and private_message client operations
3394 to deliver the message flags to the application. Added also
3395 the `flags' arguments to the silc_client_send_channel_message
3396 and silc_client_send_private_message functions. Affected file
3399 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Redefined the Private Message Payload to support private message
3402 keys and to support the new private message flags. Updated
3403 the protocol specs. Flags makes it possible to have for example
3404 CTCP style messages.
3406 * Added new type SilcPrivateMessagePayload and defined an API
3407 for it in the lib/silcclient/silcprivate.[ch].
3409 * Tested private message private keys successfully. Tested the
3410 private message key set, unset and list commands with the new
3413 * Redefined the Channel Message Payload to include the channel
3414 message flags (equal with private message flags) to support
3415 for example CTCP style messages.
3417 * Defined some of the message (for channel and private message)
3418 flags. Updated the protocol specs and added the flags to the
3419 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3421 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Added SilcKeyAgreementStatus type to the key agreement routines
3424 to indicate the current status and error if one occured.
3425 The status types are defined in the lib/silcclient/silcapi.h.
3427 * Added new local command KEY that is used to set and unset private
3428 keys for channels, set and unset private keys for private messages
3429 with remote clients and to send key agreement requests and
3430 negotiate the key agreement protocol with remote client. The
3431 key agreement is supported only to negotiate private message keys,
3432 it currently cannot be used to negotiate private keys for channels,
3433 as it is not convenient for that purpose.
3435 * Fixed a minor pending callback setting bug in the function
3436 silc_client_get_client_by_id_resolve, now the function works.
3437 Affected file lib/silcclient/idlist.c.
3439 * Added function silc_net_get_local_port to get local bound
3440 port by socket. Added to lib/silcutil/silcnet.[ch].
3442 * Added `sockets' and `sockets_count' fields to the SilcClient
3443 object. They hold the sockets of the listenning sockets in
3444 the client. Listenning sockets may be for example the key
3445 agreement server. Affected file lib/silcclient/client.[ch].
3446 Added functions the silc_client_add_socket and the
3447 silc_client_del_socket. They are exported to the application
3450 * Added ~./silc/clientkeys to support other client's public keys.
3452 * Renamed verify_server_key client operation to verify_public_key
3453 and added one argument to indicate the type of the connection
3454 (server, client etc.).
3456 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added silc_server_connection_auth_request to handle the
3459 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3460 silcd/packet_receive.[ch].
3462 * Added silc_server_send_connection_auth_request into the
3463 silcd/packet_send.c to send the connection auth request packet.
3465 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3468 * Fixed the public key authentication in responder side in the
3469 server. The `auth_data' pointer includes the SilcPublicKey
3470 not the path to the public key. Affected file silcd/protocol.c.
3472 * Implemented the public key authentication in the initiator side
3473 in the server. Affected file silcd/protocol.c.
3475 * Removed the [RedirectClient] config section from the server
3476 configuration. Is not needed and I don't want to implement it.
3478 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Cleaned up the CMODE command in the server. It now works
3481 correctly and supports all the modes defined in the protocol.
3482 Affected file is silcd/command.c.
3484 * Added `hmac_name' field to the SilcChannelEntry in the server
3485 to hold the default HMAC of the channel. It can be set when
3486 creating the channel (with JOIN command). Affected files
3489 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3490 type to indicate the change of the current cipher and hmac
3491 on the channel. Client can safely ignore the <cipher> argument
3492 (if it chooses to do so) since the CHANNEL_KEY packet will
3493 force the channel key change anyway. The <hmac> argument is
3494 important since the client is responsible of setting the new
3495 HMAC and the hmac key into use.
3497 * Fixed the CMODE command in the client library as well.
3499 * Tested CMODE command in router environment successfully.
3501 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Show the version of the remote client (or server) when connecting
3504 to the server. It is logged to the log file. Affected file
3505 is silcd/protocol.c.
3507 * Fixed the KILLED notify handling in the client library. The
3508 client must be removed from all channels when receiving the
3511 Also, do not remove the client entry when giving the KILL
3512 command but when the KILLED notify is received.
3514 * Removed silc_idlist_find_client_by_nickname from the server.
3515 Not needed anymore. Affected files silcd/idlist.[ch].
3517 * Implemented the CHANNEL_CHANGE notify type handling to the
3518 server. Affected file silcd/server.c.
3522 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added silc_server_send_notify_invite to send the INVITE
3525 notify between routers.
3527 * Implemented the INVITE command correctly to the server.

3536 * Added function silc_server_get_client_resolve to find the
3537 client entry by ID from all ID lists and then resolve it
3538 (using WHOIS) if it cannot be found. Affected file is
3541 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Implemented the BAN command to the client library.
3545 * The JOIN command in the server now checks the invite list
3548 * Changed the silc_command_reply_payload_encode_va and the
3549 silc_command_payload_encode_va to support that if argument is
3550 NULL it ignores and checks the next argument. Affected file
3551 lib/silccore/silccommand.c.
3553 * Added silc_server_send_notify_ban to send the BAN notify
3554 type between routers.
3556 * Chaned the silc_notify_payload_encode to support that if
3557 argument is NULL it ignores and checks the next argument.
3558 Affected file lib/silccore/silcnotify.c.
3560 * Tested ban lists in router environment successfully.
3562 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Implemented BAN command to the server, in silcd/command.[ch].
3566 * Removed the BAN and INVITE_LIST modes from the CMODE command
3569 * Added function silc_string_match to regex match two strings.
3570 Affected files lib/silcutil/silcutil.[ch].
3572 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Redefined parts of the SilcChannelEntry in the server to support
3575 the new ban and invite lists.
3577 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Redefined the INVITE command. The same command can be used to
3580 invite individuals to the channel but also to manage the invite
3581 list of the channel (to add to and remove from the invite list).
3582 Updated the protocol specs.
3584 * Added new command SILC_COMMAND_BAN that can be used to manage
3585 the ban list of the channel. Updated the protocol specs.
3587 * Removed the channel modes: the SILC_CMODE_BAN and the
3588 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3589 in the CMODE command. The equivalent features are now available
3590 using INVITE and BAN commands. Updated the protocol specs.
3592 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3593 in the network about change in the current ban list. The notify
3594 type is not used by the client.
3596 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3597 support the invite lists.
3599 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Added new function silc_string_regexify that converts string
3602 including wildcard characters into regex string that can
3603 be used by the GNU regex library. Added into the file
3604 lib/silcutil/silcutil.[ch].
3606 Added silc_string_regex_combine to combine to regex strings
3607 into one so that they can be used as one regex string by
3608 the GNU regex library. Added into the file
3609 lib/silcutil/silcutil.[ch].
3611 Added silc_string_regex_match to match two strings. It returns
3612 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3614 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Imported GNU regex to the soruce tree into lib/contrib.
3617 Fixed some compiler warning from the regex.c.
3619 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3623 * Fixed the MOTD command in the client library to support
3624 the server argument in the command.
3626 * Added `nickname_len' argument to the silc_idlist_add_client
3627 in the server, as the `nickname' argument may be binary data
3630 * Added silc_idlist_get_channels to return all channels from
3633 * Implemented LIST command to the server. Affected file is
3636 * Implemented the LIST command to the client library and on the
3639 * Added [<user count>] argument to the LIST command reply.
3640 With private channels the user count is not shown.
3642 * Updated TODO and README.
3644 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * The client entry's data.registered must be TRUE even with
3647 global client entry on global client list. The data.registered
3648 is used to check whether the client is anymore in the network,
3649 for example with WHOWAS command so it must be valid.
3651 * Fixed the WHOWAS command in the server. It now actually works
3652 in router environment. Added function into silcd/command_reply.c
3653 silc_server_command_reply_whowas_save.
3655 * Added silc_idlist_purge function to the silcd/idlist.c
3656 to periodically purge the ID Cache.

3666 they were buggy because of the WHOWAS information.
3668 * Fixed local command MSG to handle the async resolving of
3669 the remote client properly. It used to fail the first MSG.
3670 Affected file silc/local_command.c.
3672 * Added `data_len' field to SilcIDCache context.
3674 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Update TODO. Todo in commands in the server.
3678 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3681 used by routers as broadcast packet to inform other routers
3682 about the changed user mode.
3684 Implemented the notify handling in the server. Affected file is
3685 silcd/packet_receive.c. Added the function
3686 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3688 * Added new generic Channel Payload and deprecated the New Channel
3689 Payload. The New Channel Payload is now the generic Channel
3692 * Added new argument `mode' to the silc_server_send_new_channel
3693 as it is required in the Channel Payload now.
3695 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3696 and created a new and real SilChannelPayload to represent the
3697 new generic Channel Payload. Implemented the encode/decode
3698 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3700 * Added silc_server_get_client_channel_list to return the list
3701 of channels the client has joined for WHOIS command reply.
3702 Affected file silcd/server.[ch].
3704 * Implemented the channel list sending in the WHOIS command reply
3705 in server and in the client.
3707 Implemented the channel list displaying on the user interface
3708 as well. Affected file silc/client_ops.c.
3710 * Added silc_channel_payload_parse_list to parse list of Channel
3711 Payloads. It returns SilcDList list of SilcChannelPayloads.
3712 Client for example can use this function to parse the list of
3713 channels it receives in the WHOIS command reply. The caller
3714 must free the list by calling silc_channel_payload_list_free.
3715 Affected files lib/silccore/silcchannel.[ch].
3717 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Added one new argument <user mode> to the WHOIS command reply
3720 to return the mode of the user in SILC. Updated the protocol

3736 unknown command. Affected file silcd/command.c.
3738 * All server commands now handle the command identifier the right
3739 way when sending the command reply to the client. The client can
3740 use to identify the command replies with the identifier.
3742 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Added silc_server_get_client_route to resolve the route to
3745 the client indicated by the client ID. Affected file is
3748 * Added silc_server_relay_packet as general function to relay
3749 packet to arbitrary destination. This deprecates functions
3750 like _send_private_message_key, _relay_notify etc. Affected
3751 file is silcd/packet_send.[ch].
3753 Removed silc_server_send_key_agreement,
3754 silc_server_send_private_message_key and
3755 silc_server_packet_relay_notify functions from the file
3756 silcd/packet_send.[ch].
3760 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3761 server. Affected file silcd/packet_receive.[ch].
3763 * Implemented the KILL command to the client. Implemented the
3764 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3765 Affected files lib/silcclient/command[_reply].c and
3766 lib/silcclient/client_notify.c. Implemented the KILL notify
3767 printing in the user inteface.
3769 * Fixed a lot silc_parse_nick memory leaks from the client
3770 library in the file lib/silcclient/command.c.
3772 * Changed the silc_server_send_notify_on_channels's `sender'
3773 argument from SilcSocketConnection to SilcClientEntry to
3774 check the sender as entry and not as connection object and not
3775 to send to the client provided as argument. The affected file
3776 is silcd/packet_send.[ch].
3778 * The notify packets that are destined directly to the client used
3779 to not to be processed by the server. Now changed that and the
3780 server processes all notify packets. After relaying the packet
3781 to the client the notify packet is processed in the server.
3783 * The silc_server_free_client_data now checks whether there is
3784 pending outgoing traffic for the client and purges the data to
3785 the network before removing the client entry.
3787 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3790 an client is killed from the SILC Network. Updated the protocol
3793 Added new function silc_server_send_notify_killed to the
3794 silcd/packet_send.[ch].
3796 * Added function silc_server_packet_relay_notify to relay notify
3797 packets that are destined directly to a client. In this case
3798 the server does not process the notify packets but merely relays
3799 it to the client. Affected file silcd/packet_send.[ch].
3801 Added also silc_server_packet_process_relay_notify to check
3802 whereto relay the notify. Affected file is
3803 silcd/packet_receive.[ch].
3805 * Implemented the KILL command to the server.
3809 * Added the backup schema desgined last fall to the protocol
3810 specs for everyone to see. The specification is in the
3811 *-spec-xx.txt draft and the packet type definitions for the
3812 backup routers is in *-pp-xx.txt draft. Thusly, added also
3813 new packet type SILC_PACKET_CELL_ROUTERS.
3815 * A big security problem in the implementation discovered. The
3816 signoff of an client did not cause new channel key generation
3817 which it of course should've done. The channel keys must be
3818 always re-generated when client leaves (or signoffs) the channel.
3819 The silc_server_remove_from_channels funtion now handles
3820 the channel key re-generation.
3822 * Added `sender' argument to the silc_server_send_notify_on_channels
3823 to not to send the client provided as argument. Affected file
3824 silcd/packet_send.[ch].
3826 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Implemented OPER and SILCOPER commands into the server and
3831 * Added silc_auth_verify and silc_auth_verify_data to verify
3832 the authentication directly from the authentication payload.
3833 It supports verifying both passphrase and public key based
3834 authentication. Affected file lib/silccore/silcauth.[ch].
3836 * Added `hash' field to the SilcIDListData structure. It is the
3837 hash negotiated in the SKE protocol. Affected file is
3840 * Slight redesigning of the SilcAuthPayload handling routines.
3841 Do not send SilcPKCS but SilcPublicKey as argument.
3843 * Implemented the public key authentication support to the
3844 serverconfig. The public key is loaded from the provided path
3845 and saved as authentication data to void * pointer. Thus,
3846 changed the unsigned char *auth_data to void *auth_data;
3848 * Fixed SHUTDOWN command to send the reply before the server
3849 is shutdown. :) Affected file silcd/command.c.
3851 * Fixed fatal bug in CONNECT command. The hostname was invalid
3852 memory and server crashed. Affected file silcd/command.c.
3854 * Fixed fatal bug in CLOSE command. The server_entry became
3855 invalid but was referenced later in the command. Affected file
3858 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Fixed fatal bug in failure packet handling. Server ignored
3861 the failure and thus crashed when it came.
3865 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3868 that the command may be executed only once in (about) 2 seconds.
3869 The old SILC_CF_LAG flag is same but allows command bursts up
3870 to five before limiting.
3872 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3873 server code. Various commands now includes the CF_LAG_STRICT
3874 flag to disallow any kind of miss-use of the command.
3876 * Fixed the silc_buffer_unformat to not to allocate any data
3877 if the length of the data is zero. It used to allocate the
3878 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3880 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Changed the format of AdminConnection configuration section
3883 in the server. Added username of the admin to the format.
3884 Affected files silcd/serverconfig.[ch].
3886 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3887 to return admin configuration data by host, username and/or
3890 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Implemented WHOWAS command to the server. Added the functions:
3894 silc_server_command_whowas_parse,
3895 silc_server_command_whowas_send_reply,
3896 silc_server_command_whowas_from_client and
3897 silc_server_command_whowas_from_server
3899 * Added <Client ID> argument to the WHOWAS command reply. Updated
3900 the protocol specs accordingly.
3902 * Implemented WHOWAS command and command_reply to the client
3905 Implemented the WHOWAS printing on the user interface.
3907 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Added new argument to the WHOWAS command reply, the real name.
3910 It is an optional argument. Updated the protocol specs.
3912 * Added SilcIDCacheDestructor callback that is registered when
3913 the SilcIDCache is allocated. The callback is called when
3914 an cache entry in the ID Cache expires, or is purged from the
3915 cache. Added into lib/silccore/idcache.[ch].
3917 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3918 to destruct the client entries when the cache entry expires.
3919 Other ID Cache's in server and in the client library ignores
3922 * If the ID Cache entry's `expire' field is zero then the entry
3923 never expires. Added boolean `expire' argument to the
3924 silc_idcache_add function in the lib/silccore/idcache.[ch].
3925 If it is TRUE the default expiry value is used.
3927 * Added silc_server_free_client_data_timeout that is registered
3928 when client disconnects. By default for 5 minutes we preserve
3929 the client entry for history - for WHOWAS command.
3931 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added support to the server to enforce that commands are not
3934 executed more than once in 2 seconds. If server receives
3935 commands from client more frequently, timeout is registered
3936 to process the commands. Affected file silcd/command.c.
3937 Added new function silc_server_command_process_timeout.
3939 * Changed NICK_NOTIFY handling in client library to check that
3940 if the client's nickname was changed, so there is no need to
3941 resolve anything from the server.
3943 * Removed error printing from the WHOIS and IDENTIFY commands.
3944 If error occurs then it is ignored silently in the client library.
3945 The application, however, may map the received error to
3946 human readable error string. The application currently maps
3947 the NO_SUCH_NICKNAME error to string.
3949 * Made the command status message public to the application. Moved
3950 them from lib/silcclient/command_reply.c to
3951 lib/silcclient/command_reply.h. The application can map the
3952 received command status to the string with the
3953 silc_client_command_status_message function.
3955 * Added check to the server to check that client's ID is same
3956 as the Source ID in the packet the client sent. They must
3959 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Added dist-bzip hook to the Makefile.am to make bzip2
3962 compressed distributions.
3964 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Server now enforces the maximum length for the nickname and
3967 the channel as protocol specification dictates. 128 bytes for
3968 nickname and 256 bytes for channel name.
3970 * Moved the WHOIS printing to the application. The client libary
3971 does not print out the WHOIS information anymore, the application
3972 must do it. Renamed silc_client_command_reply_whois_print to
3973 the silc_client_command_reply_whois_save.
3975 The client's idle time is also sent to the application now, and
3976 the idle is shown on screen.
3978 * Added silc_client_command_reply_identify_save to save the
3979 received IDENTIFY entries.
3981 * Do not check for channel private keys in message sending and
3982 reception if the channel does not have the PRIVKEY mode set.
3983 Affected file lib/silclient/client_channel.c.
3985 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3988 just surfaced after chaning the JOIN procedure.
3990 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Added silc_client_get_clients_by_list to get client entries
3993 from Client ID list, that is returned for example by JOIN
3994 and USERS command replies. The application should use this
3995 function for example when JOIN command reply is received to
3996 resolve the clients already on the channel (library does not
3997 do that anymore as USERS command reply is not used in the JOIN
3998 procedure anymore). Affected files lib/silcclient/silcapi.h and
3999 lib/silcclient/idlist.c.
4001 * JOIN command reply and USERS command reply returns now SilcBuffer
4002 pointers instead of unsigned char pointers when returning
4003 the client list and mode list.
4005 * Added <Client ID> argument to the JOIN command reply, mainly
4006 for the server to identify for which client the command was
4007 originally sent. Updated protocol specs accordingly.
4009 * Added SilcDlist private_key pointer to the SilcChannelEntry
4010 in the client to support the channel private keys. Affected
4011 file is lib/silcclient/idlist.h.
4013 * Added SilcChannelPrivateKey argument to the function
4014 silc_client_send_channel_message so that application can choose
4015 to use specific private ke if it wants to. If it is not provided,
4016 the normal channel key is used, unless private keys are set.
4017 In this case the first (key that was added first) is used
4018 as the encryption key.
4020 * Implemented the support for channel private key handling.
4021 Implemented the following functions:
4023 silc_client_add_channel_private_key,
4024 silc_client_del_channel_private_keys,
4025 silc_client_del_channel_private_key,
4026 silc_client_list_channel_private_keys and
4027 silc_client_free_channel_private_keys
4029 Affected file lib/silcclient/client_channel.c.
4031 * Added the support for the private keys in the channel message
4032 sending and encryption and in the message reception and
4033 decryption. Affected funtions are
4034 silc_client_send_channel_message and silc_client_channel_message.
4036 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Added SKE's key verify callback to the client library's
4039 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4041 * Removed the statement that server (or router) must send USERS
4042 command reply when joining to the channel so that the client
4043 knows who are on the channel. Instead, the client list and
4044 client's mode list is now sent in the JOIN command reply to the
4045 client who joined channel. This is better solution.
4047 * Added function silc_server_get_users_on_channel and function
4048 silc_server_save_users_on_channel to the silcd/server.[ch].
4050 * Removed function silc_server_command_send_users from the
4053 * Do not show topic on the client library anymore. The topic is
4054 sent in the command reply notify to the application and the
4055 application must show the topic now.
4057 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Added client searching by nickname hash into the IDENTIFY and
4060 WHOIS commands in the server as they were clearly missing from
4061 them. Affected file is silcd/command.c.
4063 * Fixed a bug in private message receiving in the client library.
4064 The remote ID was freed and it wasn't supposed, now it is
4067 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Minor fix to the channel payload; allocate the data area, as it
4070 needs to be of specific length.
4072 * If the key agreement port is zero then the operating
4073 system will define the bound port. Affected files are
4074 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4076 * Added new function silc_channel_payload_decrypt into the file
4077 lib/silccore/silcchannel.[ch].
4079 * Moved the channel message etc, check from silc_packet_decrypt
4080 to applications. The library calls now a generic
4081 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4082 when the packet is either normal or special. This was done to
4083 allow more wide range of checking that was not allowed when
4084 the code was in library. Now applications can do virtually any
4085 checks to the packet and return to the library the decision how
4086 the packet should be processed. Affected files are
4087 lib/silccore/silcpacket.[ch].
4089 Added silc_server_packet_decrypt_check to the server and
4090 silc_client_packet_decrypt_check to the client library.
4092 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4093 to send with specified source and destination information.
4095 * Channel message delivery between routers was broken after the
4096 channel key distribution was fixed earlier. The channel key
4097 was used be to distributed to other routers as well which is not
4098 allowed by the protocol. Now this is fixed and channel keys
4099 really are cell specific and the channel message delivery between
4100 routers comply with the protocol specification.
4102 * Fixed various commands in server to check also the global list
4103 for the channel entry and not just the local list. The affected
4104 file silcd/command.c.
4106 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Added assert()s to buffer formatting and unformatting routines
4109 to assert (if --enable-debug) when error occurs. Affected
4110 file: lib/silcutil/silcbuffmt.c.
4112 * Changed to auto-reconnect to check whether the remote host is
4113 router and register the re-connect timeout if it is. It used
4114 to check that whether we are normal server, but router must do
4115 auto-reconnect with another router as well. Affected file
4118 * Removed the [<key len>] option from CMODE command as the cipher
4119 name decides the key length, nowadays. See the defined ciphers
4120 from the protocol specification.
4122 * Added [<hmac>] option to the CMODE command to define the HMAC
4123 for the channel. Added SILC_CMODE_HMAC channel mode.
4125 * Added [<hmac>] option for the JOIN command so that user can
4126 select which HMAC is used to compute the MACs of the channel
4129 * Added Hmac field to the Channel Message Payload. The integrity
4130 of plaintext channel messages are now protected by computing
4131 MAC of the message and attaching the MAC to the payload. The
4132 MAC is encrypted. Now, it is clear that this causes some
4133 overhead to the size of the packet but rationale for this is that
4134 now the receiver can verify whether the channel message decrypted
4135 correctly and also when private keys are set for the channel the
4136 receiver can decrypt the packet with several keys and check from
4137 the MAC which key decrypted the message correctly.
4139 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4140 lib/silccrypt/silccipher.[ch].
4142 * Added silc_hash_len to return the digest length into the
4143 lib/silcrypt/silchash.[ch].
4145 * Rewrote parts of Silc Channel Payload interface in the
4146 lib/silccore/silcchannel.[ch]. The encode function now also
4147 encrypts the packet and parse function decrypts it.
4149 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Fixed a minor formatting bug in the SKE's key material processing.
4152 It actually might have processed the keys wrong way resulting
4155 * Redefined the mandatory HMAC algorithms and added new algorithms.
4156 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4157 and hmac-md5 truncated to 96 bits. The mandatory is now
4158 hmac-sha1-96. Rest are optional (including the one that used
4159 to be mandatory). Rationale for this is that the truncated HMAC
4160 length is sufficient from security point of view and can actually
4161 make the attack against the HMAC harder. Also, the truncated
4162 HMAC causes less overhead to the packets. See the RFC2104 for
4165 * Added new [hmac] configuration section. The SKE used to use
4166 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4167 is of course wrong. The official names that must be proposed in
4168 the SKE are the ones defined in the protocol specification
4169 (hmac-sha1-96 for example). The user can configure any hmac
4170 using any hash function configured in the [hash] section. At
4171 least, the mandatory must be configured.
4173 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4175 * Added HMAC list to the SKE proposal list. It has now both
4176 hash algorithm list and HMAC list. This makes the protocol
4177 incompatible with previous versions. The SKE now seems to work
4178 the way it is supposed to work, for the first time actually.
4180 * Defined plain Hash algorithms to the protocol specification.
4183 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Implemented support for key agreement packets into the server.
4186 Added functions silc_server_key_agreement and
4187 silc_server_send_key_agreement. Other than these functions,
4188 server has nothing to do with this packet.
4190 * Added support for private message key packets into the server.
4191 Added functions silc_server_private_message_key and
4192 silc_server_send_private_message_key.
4196 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4197 called in the protocol's final callback instead in the END
4198 protocol state. This makes a little more sense and in the same
4199 time in client we can use the same protocol routines for normal
4200 key exchange and to key agreement packet handling as well.
4202 * Added to both client's and server's KE protocol context the
4203 SilcSKEKeyMaterial pointer to save the key material. We will
4204 bring the key material to the protocol's final callback by doing
4205 this. The final callback must free the key material.
4207 * Added SKE's packet_send callback into client's KE protocol
4208 context so that the caller can choose what packet sending function
4209 is used. This way we can use different packet sending when
4210 doing normal SKE when doing key agreement packet handling (in
4211 the key agreement packet handling we do not want to encrypt
4214 * Implemented the responder side of the key agreement routines
4215 in the client. The client can now bind to specified port and
4216 accept incoming key negotiation. The key material is passed
4217 to the application after the protocol is over.
4219 * Implemented the processing of incoming Key Agreement packet
4220 in the client. Added function silc_client_key_agreement to
4223 * Implemented the intiator side of the key agreement routines
4224 in the client. The client can now initiate key agreement with
4225 another remote client. The key material is passed to the
4226 application after the protocol is over.
4228 * Created client_keyagr.c to include all the key agreement
4231 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4232 SILC_TASK_CALLBACK except that it is not static.
4234 * Created client_notify.c and moved the Notify packet handling
4235 from the client.[ch] into that file.
4237 * Created client_prvmsg.c and moved all private message and
4238 private message key routines from the client.[ch] into that file.
4240 * Create client_channel.c and moved all channel message and
4241 channel private key routines from the client.[ch] into that file.
4243 * Changed silc_client_get_client_by_id_resolve to resolve with
4244 WHOIS command instead of IDENTIFY command, in the file
4245 lib/silclient/idlist.c.
4247 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Implemented the SKE's responder side to the Client library.
4251 * When FAILURE is received to the protocol do not trust it
4252 blindly. Register a timeout to wait whether the remote closes
4253 the connection as it should do it, only after that process the
4254 actual failure. This was changed to both client and server.
4256 * Added client_internal.h to include some of the structures
4257 there instead of client.h in lib/silcclient/.
4259 * Added function silc_task_unregister_by_callback to unregister
4260 timeouts by the callback function.
4262 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4264 * Some "Incomplete WHOIS info" errors has been appearing on the
4265 log files. Took away the entry->userinfo check from WHOIS
4266 reply sending. The entry->userinfo is now " " if client did not
4267 provide one. I thought this was fixed earlier but something
4268 is wrong still. Let's see if the error still appears.
4270 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Fixed a minor bug in the login when the channel key is
4273 re-generated in the server. It used to generate the key in
4274 wrong order and thus caused problems in the channel traffic.
4276 * Fixed a minor bug in channel key distsribution after
4277 KICK command. The key was not sent to the router even though
4280 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Added silc_ske_process_key_material_data as generic routine
4283 to process any key material as the SILC protocol dictates. The
4284 function is used by the actual SKE library but can be used by
4285 applications as well. This relates to the private message keys
4286 and the channel private keys since they must be processed the
4287 same way the normal SILC session keys. The protocol dictates
4288 this. Affected files: lib/silcske/silcske.[ch].
4290 Added also silc_ske_free_key_material to free the
4291 SilcSKEKeyMaterial structure.
4293 * Defined silc_cipher_set_key function to set the key for
4294 cipher without using the object's method function. The affected
4295 files: lib/silccrypt/silccipher.[ch].
4297 * Implemented silc silc_client_add_private_message_key,
4298 silc_client_add_private_message_key_ske,
4299 silc_client_del_private_message_key,
4300 silc_client_list_private_message_keys and
4301 silc_client_free_private_message_keys functions in the
4304 Added functions silc_client_send_private_message_key to send
4305 the Private Message Key payload and silc_client_private_message_key
4306 to handle incoming Private Message Key payload.
4308 * Added Cipher field to the Private Message Key payload to set
4309 the cipher to be used. If ignored, the default cipher defined
4310 in the SILC protocol (aes-256-cbc) is used.
4312 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Removed lib/silcclient/ops.h file.
4316 Redefined parts of the SILC Client Library API. Created new
4317 file silcapi.h that deprecates the ops.h file and defines the
4318 published Client Library API. Defined also private message key
4319 API and channel private key API into the file.
4321 This is the file that the application must include from the
4322 SILC Client Library. Other files need not be included by
4323 the application anymore.
4325 * Added new key_agreement client operation callback and also
4326 defined the Key Agreement library API for the application.
4328 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4331 is used by clients to request key negotiation between another
4332 client in the SILC network. If the negotiation is started it
4333 is performed using the SKE protocol. The result of the
4334 negotiation, the secret key material, can be used for example
4335 as private message key.
4337 Implemented the Key Agreement payload into the files
4338 lib/silccore/silauth.[ch].
4340 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Redefined ciphers for the SILC protocol. Added some new ciphers
4343 and defined the key lengths for the algorithms. Changed the
4344 code accordingly. The default key length is now 256 bits.
4346 * Fixed SKE key distribution function silc_ske_process_key_material
4347 when the key length is more than 128 bits. The default key
4348 length in SILC is now 256 bits.
4350 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4351 to indicate unsupported algorithm.
4353 * Renamed rijndael.c to aes.c and all functions as well.
4355 * Fixed a long standing channel key setting bug in client library.
4356 Weird that it has never surfaced before.
4358 * Fixed bug in channel deletion. If the entire channel is removed
4359 then it must also delete the references of the channel entry
4360 from the client's channel list as the client's channel entry and
4361 the channel's client entry share same memory.
4363 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Implemented CONNECT and SHUTDOWN commands in the client.
4367 * Implemented CLOSE command to the client.
4369 * Added the function silc_idlist_find_server_by_name into the
4370 files silcd/idlist.[ch].
4372 Added the function silc_idlist_find_server_by_conn into the
4373 files silcd/idlist.[ch].
4375 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * DIE command was renamed to SHUTDOWN. Updated the both code
4380 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4381 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4383 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4386 * Added function silc_server_create_connection function to create
4387 connection to remote router. My server implementation actually
4388 does not allow router to connect to normal server (it expects
4389 that normal server always initiates the connection to the router)
4390 so the CONNECT command is only good for connecting to another
4393 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4396 or some other client was kicked from the channel.
4398 Implemented the handling of the notify type to both client
4401 Implemented silc_server_send_notify_kicked to send the KICKED
4402 notify. It is used to send it to the server's primary router.
4404 * Implemented the KICK command into server and client.
4406 * Added `query' argument to the silc_idlist_get_client function
4407 to indicate whether to query the client from server or not if
4410 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4411 to indicate that the client is not channel founder.
4415 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Removed the rng context from SilcPacketContext structure and
4418 changed that the packet routine uses the Global RNG API.
4420 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added support for quit message that client can "leave" on the
4423 channel when it quits the SILC. It is ditributed inside the
4424 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4426 Added silc_server_free_client_data that will take the
4427 signoff message as argument.
4429 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4431 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Updated parts of the protocol specification to keep it up
4436 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4439 payloads in one packet.
4441 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4442 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4443 use now the new List flag.
4445 * Also deprecated the following packet types: REPLACE_ID,
4446 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4448 * Added list support for Notify packet in server.
4450 * Added silc_server_send_notify_channel_change to send the
4451 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4452 the silc_server_send_replace_id.
4454 * Added silc_server_send_notify_nick_change to send the
4455 NICK_CHANGE notify type. Deprecates the function
4456 silc_server_send_replace_id.
4458 * Added silc_server_send_notify_join to send the JOIN notify type.
4459 Deprecates the function silc_server_send_new_channel_user.
4461 * Added silc_server_send_notify_leave to send LEAVE notify type.
4462 Deprecates the function silc_server_send_remove_channel_user.
4464 * Added silc_server_send_notify_cmode and
4465 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4466 types. Deprecates the silc_server_send_set_mode function.
4468 * Added SERVER_SIGNOFF notify type to indicate that server has
4469 quit. This means that all clients on the channel from that
4470 server will drop. This can be also used when netsplit happens.
4472 Deprecated REMOVE_ID packet type since it is not needed anymore
4475 Added silc_server_send_notify_server_signoff to send the
4476 SERVER_SIGNOFF notify type. Deprecates the function
4477 silc_server_send_remove_id.
4479 Added also silc_server_send_notify_signoff to send the
4480 SIGNOFF notify type.
4482 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4483 SILC protocol from this day on. Changed the protocol
4484 specification as well.
4486 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4487 notify type. It is used between routers to notify about
4488 topic changes on a channel.
4490 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4493 * Partly updated the protocol specification to comply with the
4494 changes now made. It is still though a bit outdated.
4496 * The JOIN notify type now takes one extra argument <Channel ID>.
4497 The packet used to be destined to the channel but now the
4498 JOIN type may be sent as list thus it is impossible to
4499 destine it to any specific channel. By adding this argument
4500 it is again possible.
4502 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Added CREDITS file. The CHANGES and CREDITS file will appear
4505 in the distribution as well.
4507 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4510 types in the server's silcd/packet_receive.c.
4512 * Implemented CMODE and CUMODE to work in router environment.
4514 * Fixed minor encoding and decoding buglet from the
4515 lib/silccore/silcmode.c.
4517 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4520 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4522 * Changed all SilcConfigServer* and silc_config_server* to
4523 SilcServerConfig* and silc_server_config*, respectively.
4526 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Associated the ID (client or server ID) to the Authentication
4529 Payload to avoid any possibility of forging. Updated the
4530 protocol specification and the code accordingly.
4532 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * The RSA key length is now save to the RsaKey context in the
4535 key generation process in lib/silccrypt/rsa.c. The key length
4536 is now used to figure out the maximum size of the block allowed
4537 to be encrypted/signed.
4539 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4540 is equivalent to the silc_mp_mp2bin but does not allocate any
4543 * Changed silc_mp_mp2bin API to take length argument. If it is
4544 non-zero then the buffer is allocated that large. If zero, then
4545 the size is approximated using silc_mp_sizeinbase, which however
4548 * Created Global RNG API which is global RNG that application can
4549 initialize. After initializing, any routine anywhere in the
4550 code (including library) can use RNG without allocating a new
4551 RNG object. This was done to allow this sort of use of the
4552 RNG in code that has no chance to allocate RNG object. All
4553 applications currently allocate this and many routines in the
4554 library use this. Affected file lib/silccrypt/silcrng.[ch].
4556 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4557 it to use the Global RNG API.
4559 * Defined Authentication Payload into protocol specification that
4560 is used during SILC session to authenticate entities. It is
4561 used for example by client to authenticate itself to the server
4562 to obtain server operator privileges.
4564 Implemented this payload into the lib/silccore/silcauth.[ch].
4565 Implemented also routines for public key based authentication
4566 as the new protocol specification dictates.
4568 Moved definitions of different authentication methods from
4569 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4571 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4572 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4573 silc_pkcs_verify_with_hash functions into the file
4574 lib/silccrypt/silcpkcs.[ch].
4576 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * The client entry's userinfo pointer must be always valid.
4579 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4580 will fail since it requires the userinfo. Now, the userinfo
4581 is allocated as "" if actual userinfo does not exist. Actually,
4582 it must exist and it is totally Ok to drop client connections
4583 that does not announce the userinfo. However, we will make
4584 this workaround for now.
4586 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4587 to return the remote port by socket.
4589 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4592 SILC_SERVER_PENDING_EXEC and added an new macro
4593 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4594 data or when error occurs while processing the pending command.
4596 Added new argument `destructor' into silc_server_command_pending
4597 and to the SilcServerCommandPending object. This destructor is
4598 now called after calling the pending callback or if error occurs
4599 immediately. If error occurs the actual pending callback won't
4600 be called at all - only the destructor. The destructor may be
4601 NULL if destructor is not needed.
4603 All this applies for client library code as well. Similar
4604 changes were made there as well for the pending commands.
4606 In the client, the application must now allocate the
4607 SilcClientCommandContext with the silc_client_command_alloc
4610 * Added reference counter to the SilcServerCommandContext. Added
4611 function silc_server_command_alloc and silc_server_command_dup
4614 Same type of functions added to the client library for the same
4617 * Removed the cmd_ident from IDListData away since it is now
4618 global for all connections. It is the command identifier used
4619 in command sending and with pending commands. The affected file
4622 * Added reference counter to the SilcSocketConnection objecet to
4623 indicate the usage count of the object. The object won't be
4624 freed untill the reference counter hits zero. Currently only
4625 server uses this, and client ignores it. The client must be
4626 set to use this too later. The affected files are
4627 lib/silccore/silcsockconn.[ch]. Added also the function
4628 silc_socket_dup to increase the reference counter.
4630 This was mainly added because it is possible that the socket
4631 is removed underneath of pending command or other async
4632 operation. Now it won't be free'd and proper DISCONNECTING
4633 flags, etc. can be set to avoid sending data to connection that
4634 is not valid anymore.
4636 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4637 the connection. After that it sets SILC_SET_DISCONNECTED.
4638 It is, however, possible that the socket data is not still freed.
4639 The silc_server_packet_process now checks that data is not
4640 read or written to connection that is DISCONNECTED. The socket
4641 get's freed when the reference counter hits zero.
4643 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Changed the client operation API: channel_message operation's
4646 `sender' is now the client entry of the sender, not the nickname
4647 and the `channel' is the channel entry, not the channel name.
4649 In the private_message operation the `sender' is now also the
4650 client entry of the sender not the nickname.
4652 Affected file is lib/silcclient/ops.h and all applications
4653 using the client operations.
4655 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Moved the calling of ops->connect() from connect_to_server_final
4658 into receive_new_id functin since that is the point when the
4659 client is actually allowed to send traffic to network. The
4660 affected file is lib/silcclient/client.c.
4662 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4665 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4666 (if needs broadcasting) instead of broadcasting the packets one
4667 by one which would make a burst in the network traffic.
4669 * Added `broadcast' argument to the functions in silcd/server.[ch]
4670 silc_server_create_new_channel[_with_id] to indicate whether
4671 to send New Channel packet to primary router.
4673 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Added new function into the silcd/server.[ch] files:
4676 silc_server_create_new_channel_with_id to create new channel with
4677 already existing Channel ID.
4679 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4680 lib/silccore/silcpacket.h. This packet is used t send list of
4681 Set Mode payloads inside one packet. Server uses this to set
4682 the modes for the channels and clients on those channels, that it
4683 announced to the router when it connected to it. The protocol
4684 specification has been updated accordingly.
4686 * The silc_server_new_channel did not handle the packet coming
4687 from normal server as it normally does not send that. However,
4688 when it announces its channels it does send it. Implemented
4689 the support for that.
4691 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4692 into the file lib/silccore/id.h.
4694 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Fixed memory leaks in the functions silc_idlist_del_client,
4697 silc_idlist_del_channel and silc_idlist_del_server in the file
4698 silcd/idlist.c. All of those leaked like a sieve.
4700 * Fixed some small memory leaks in the client's function
4701 silc_client_notify_by_server.
4703 * Added functions into silcd/server.c: silc_server_announce_clients,
4704 silc_server_announce_channels and silc_server_announce_server.
4705 These functions are used by normal and router server to announce
4706 to its primary router about clients, channels and servers (when
4707 router) that we own. This is done after we've connected to the
4710 These functions effectively implements the following packet types:
4711 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4712 and SILC_PACKET_NEW_ID_LIST.
4714 * Added new functions into the silcd/packet_receive.[ch]:
4715 silc_server_new_id_list, silc_server_new_channel_list and
4716 silc_server_new_channel_user_list to handle the incoming
4717 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4719 * Added support of changing Channel ID in the function
4720 silc_server_replace_id. If the server that announces a channel
4721 to the router already exists in the router (with same name but
4722 with different Channel ID), router is responsible to send
4723 Replace ID packet to the server and force the server to change
4724 the Channel ID to the one router has.
4726 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4727 client that the Channel ID has been changed by the router. The
4728 normal server sends this to the client. Client must start using
4729 the new Channel ID as the channel's ID.
4731 Implemented handling of this new type into lib/silcclient/client.c
4732 into the function silc_client_notify_by_server.
4734 * Added new function silc_idlist_replace_channel_id into the files
4735 silcd/idlist.[ch] to replace the Channel ID.
4737 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Call silc_server_command_identify_check always when processing
4740 the IDENTIFY command in silcd/command.c
4742 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4745 send keepalive packets. The packet can be sent by clients,
4746 servers and routers.
4748 Added function silc_socket_set_heartbeat into the file
4749 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4750 If not set, the heartbeat is not performed. The actual
4751 heartbeat is implemented in the low level socket connection
4752 library. However, application is responsible of actually
4755 Added silc_server_send_heartbeat to send the actual heartbeat
4756 packet into silcd/packet_send.[ch]. Server now performs
4757 keepalive with all connections.
4759 * Added silc_task_get_first function into lib/silcutil/silctask.c
4760 to return the timeout task with shortest timeout. There was a bug
4761 in task unregistration that caused problems. TODO has been
4762 updated to include that task system must be rewritten.
4764 * The client library will now resolve the client information when
4765 receiving JOIN notify from server for client that we know but
4766 have incomplete information.
4768 * Rewrote parts of silc_server_remove_from_channels and
4769 silc_server_remove_from_one_channel as they did not remove the
4770 channel in some circumstances even though they should've.
4772 * Encryption problem encountered in server:
4774 The LEAVE command used to send the Channel Key packet to the
4775 router immediately after generating it. However, the code
4776 had earlier sent Remove Channel user packet but not immediately,
4777 ie. it was put to queue. The order of packets in the router
4778 was that Channel Key packet was first and Remove Channel User
4779 packet was second, even though they were encrypted in the
4780 reverse order. For this reason, MAC check failed. Now, this
4781 is fixed by not sending the Channel Key packet immediately but
4782 putting it to queue. However, this is more fundamental problem:
4783 packets that are in queue should actually not be encrypted
4784 because packets that are sent immediately gets encrypted
4785 actually with wrong IV (and thus MAC check fails). So, packets
4786 that are in queue should be encrypted when they are sent to
4787 the wire and not when they put to the queue.
4789 However, the problem is that the current system has not been
4790 designed to work that way. Instead, the packet is encrypted
4791 as soon as possible and left to the queue. The queue is then
4792 just purged into wire. There won't be any fixes for this
4793 any time soon. So, the current semantic for packet sending
4796 o If you send packet to remote host and do not force the send
4797 (the packet will be in queue) then all subsequent packets to the
4798 same remote host must also be put to the queue. Only after the
4799 queue has been purged is it safe again to force the packet
4802 o If you send all packets immediately then it safe to send
4803 any of subsequent packets through the queue, however, after
4804 the first packet is put to queue then any subsequent packets
4805 must also be put to the queue.
4807 Follow these rules and everything works fine.
4809 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added new function silc_server_remove_clients_by_server to
4812 remove all client entries from ID list when the server connection
4813 is lost. In this case it is also important to invalidate all
4814 client entires as they hold the invalid server entry. This
4815 fixes fatal bug when server has lost connection and will reconnect
4818 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Made some sanity checks to silc_server_daemonise like to check
4821 whether the requested user and group actually exists.
4823 * Added sanity check to SKE's silc_ske_responder_finish to check
4824 that the public and private key actually is valid.
4826 * Invalidate the client's nickname when receiving Replace ID
4827 packet and the Client ID is being replaced. This means that the
4828 server will query the nickname if someone needs it (client)
4831 * Sort the ID Cache in client library when the ID Cache data
4832 has changed (needs sorting).
4834 * Do not allow for SILC client to create several connections to
4835 several servers. The client does not support windows right now
4836 and generating multiple connections causes weird behaviour.
4838 Irssi-silc client does support windows and can handle several
4839 connections without problems, see: www.irssi.org and SILC plugin.
4841 * Fixed some places where client was added to the IDList. The
4842 rule of thumb is following (in order to get everything right):
4843 If the client is directly connected local client then the
4844 `connection' argument must be set and `router' argument must be
4845 NULL to silc_idlist_add_client function. If the client is not
4846 directly connected client then the `router' argument must
4847 bet set and the `connection' argument must be NULL to the
4848 silc_idlist_add_client function.
4850 * The funtion silc_server_packet_send_local_channel actually did
4851 not check whether the client was locally connected or not. It
4852 does that now. Fixed a bug related to LEAVE command.
4854 * Fixed Remove Channel User payload parsing bug in server's
4855 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4857 * The server's silc_server_save_channel_key now checks also the
4858 global ID list for the channel as it might not be in the local
4859 list. Fixed a bug related to LEAVE command.
4861 * Is this the end of the [<unknown>] buglet that has been lurking
4862 around for a long time? A little for loop fix in server's
4863 silc_server_command_whois_parse that is used by both IDENTIFY
4864 and WHOIS command. At least, this was a clear bug and a cause
4865 of one type of [<unknown>] buglet.
4867 * WHOIS and IDENTIFY commands call the function
4868 silc_server_command_[whois/identify]_check function even if
4869 we are not router server.
4871 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Added --with-gmp configuration option. If set the GMP
4874 is always compiled in the SILC source tree. If not set then
4875 it is checked whether the system has the GMP3 installed. If
4876 it has then the GMP won't be compiled (the system's headers
4877 and library is used), if it doesn't have it then the GMP is
4878 compiled in the SILC source tree.
4880 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Changed RSA private exponent generation to what PKCS #1
4883 suggests. We try to find the smallest possible d by doing
4884 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4885 not security fix but optimization.
4887 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added new config entry [Identity] to fork the server and run
4890 it as specific user and group. A patch from Bostik.
4892 * Imported Dotconf configuration library into lib/dotconf.
4893 This will be used to create the SILC configuration files later.
4894 It will appear in the distsribution after this commit.
4896 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * A big code auditing weekend happening. Auditing code for
4899 obvious mistakes, bugs and errors. Also, removing any code
4902 Removed files for being obsolete:
4904 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4905 inline in the file lib/silcutil/silcbuffer.h)
4907 o lib/silcutil/silcbufutil.c (the header has inline versions)
4909 Changed code to fix possible error conditions:
4911 o The buffer formatting routines now check that the destination
4912 buffer really has enough space to add the data. This applies for
4913 both buffer formatting and unformatting
4914 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4915 unformatting was changed to accomodate following rules:
4916 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4917 sent to the function while XXX_*STRING will not allocate or copy
4918 the data into the buffer. Instead it sets the pointer from the
4919 buffer into the pointer sent as argument (XXX_*STRING used to
4920 require that the pointer must be allocated already). This change
4921 makes this whole thing a bit more consistent and more optimized
4922 (note that the data returned in the unformatting with XXX_*STRING
4923 must not be freed now). The routines return now -1 on error.
4925 o Tried to find all code that use buffer_format and buffer_unformat
4926 and added return value checking to prevent formatting and
4927 especially unformatting errors and possible subsequent fatal
4930 o Changed ske->x and ske->KEY to mallocated pointers in
4931 lib/silcske/silcske.h. Fixed possible data and memory leak.
4933 o Added return value checking to all *_parse* functions. Fixed
4934 many memory leaks as well.
4936 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4937 so that buffer overflows would not happen. All code now also
4938 checks the return value as it can fail.
4940 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Added reconnection support to server if the normal server looses
4943 its connection to the router (for example if router is rebooted).
4944 The server performs normal reconnection strategy implemented
4945 to the server. Affected file silcd/server.c.
4947 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added new packet type SILC_PACKET_SET_MODE that is used to
4950 distribute the information about changed modes (for clients,
4951 channels and clients channel modes) to all routers in the
4952 network. Updated the protocol specification accordingly.
4954 Added functions into silcd/packet_send.c and
4955 silcd/packet_receive.c: silc_server_send_set_mode,
4956 silc_server_set_mode.
4958 Added new files silcmode.[ch] into lib/silccore that implements
4959 the encoding and decoding of Set Mode Payload. Added new type
4960 SilcSetModePayload. Moved the definitions of different modes
4961 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4963 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Oops, a little mistake in server's connection authentication
4966 protocol. The protocol is not ended with FAILURE but with
4967 SUCCESS if the authentication is Ok. :) Affected file is
4970 * Implemented NICK_CHANGE notify handling in server in the file
4971 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4972 the local clients on the channel. After the changing nickname
4973 in router environment snhould work and the [<unknown>] nickname
4974 should appear no more.
4976 The silc_server_replace_id function that receives the Replace ID
4977 payload now sends the NICK_CHANGE notify type also in the file
4978 silcd/packet_receive.c
4980 * Changed WHOIS and IDENTIFY command to support the maximum amount
4981 of arguments defined in protocol specs (3328 arguments). This
4982 fixed a bug that caused problems when there were more than three
4985 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Added extra parameter, command identifier, to the
4988 silc_client_send_command so that explicit command identifier
4991 Changed that ID list routines uses specific command identifier
4992 when sending WHOIS/IDENTIFY requests to the server so that they
4993 can be identified when the reply comes back.
4995 Affected files lib/silcclient/command.[ch],
4996 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4998 * Added `sender' argument to silc_server_packet_send_to_channel
4999 to indicaet the sender who originally sent the packet to us
5000 that we are now re-sending. Ignored if NULL. Affected file
5001 silcd/packet_send.[ch].
5003 * Added some server statistics support in silcd/server_internal.h
5004 SilcServerStatistics structure and around the server code. Also
5005 send some nice statistics information when client is connecting
5008 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Fixed channel ID decoding in server's JOIN command reply in
5011 silcd/command_reply.c
5013 * Fixed braodcasting of replace ID payload to not to send it if
5014 we are standalone server in silcd/packet_receive.c.
5016 * Fixed all channel message sending routines to not to send
5017 packets to clients that has router set, since they are routed
5018 separately in the same function earlier. Affects file
5019 silcd/packet_send.c and all channel packet sending functions.
5021 * In USERS reply, res_argv[i] are not allocated, the table
5022 is allocated. Thus changed that free the table, not its
5025 * In server's whois_check and identify_check if the client is
5026 locally connected do not send any WHOIS commands - they are not
5029 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Fixed some minor bugs in client when sending WHOIS command. The
5032 arguments was in wrong order.
5034 * Removed statis function add_to_channel from server in
5035 silcd/command.c that was previously used with the joining but
5038 * Tested USERS command in router environment successfully with two
5039 routers, two servers and two clients.
5041 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Reorganized the USERS command and command reply in client library
5044 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5045 When the command is given by user we register a pending command
5046 callback that will reprocess the command after the reply has been
5047 received from the server. When reprocessing the packet we then
5048 display the information. Thus, the USERS information is displayed
5049 now in the command callback instead of in the command reply
5050 callback. The processing of the command is same as previously
5051 when server has sent the command reply in the JOINing process.
5053 * Added to USERS command in silcd/command_reply.c to join the client,
5054 we didn't use to know about, to the channel after we've created
5055 a client entry for it. Also, for clienet we did know already still
5056 check whether it is on the channel or not and add it if not.
5058 * Removed silc_server_command_join_notify as the function and its
5061 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Changed the client's pending command handling to the same as the
5064 server's pending command handling. It is also now possible to
5065 execute command reply functions from other command reply
5066 function as the function callbacks for commands and command
5067 replies are one and same. The pending commands are not static
5068 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5069 in client connection context. Thus, pending commands are server
5070 connection specific as it is convenient.
5072 Changed the function silc_client_command_pending and
5073 silc_client_command_pending_del and added new function
5074 silc_client_command_pending_check. Removed the
5075 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5078 * Added cmd_ident, current command identifier, to the client
5079 connection context in lib/silcclient/client.h to keep track on
5080 command identifiers used in command sending. Client's command reply
5081 function handling now supports the mandatory command identifiers.
5083 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5084 funtions in client to fully support pending command callbacks.
5086 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5087 as one of the arguments to the application in the command reply
5090 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5091 before first releasing SILC but came back. Now it is removed again
5092 and should come back nomore. The FORWARDED flag was used only
5093 by the JOINing procedure by forwarding the command packet to router.
5094 Now, the JOINing procedure has been changed to more generic (due
5095 to various router environment issues) and FORWARDED is not needed
5096 anymore for anything. The protocol specification is yet to be
5099 Now, removed silc_server_packet_forward from server and the flag
5100 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5102 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Renamed NAMES command to USERS command. The NAMES was named that
5105 due to historical reasons. Now it is renamed. Also, rewrote
5106 parts of the USERS command. The nickname list is not sent anymore
5107 by the server. Only Client ID and mode lists are sent in the USERS
5108 command. Changed this also to the protocol specification.
5110 The client now resolves the names and stuff after it receives
5111 the USERS list from the server when joining to the channel.
5113 * WHOIS and IDENTIFY commands has been changed to support multiple
5114 Client ID's per command. One can now search for multiple users
5115 in the network by sending only one WHOIS or IDENTIFY command.
5116 Changed the code and the protocol specifications.
5118 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5119 uses silc_server_command_whois_parse to parse the request. */
5121 * If normal server, do not parse the WHOIS and IDENTIFY requests
5122 before sending it to the router. Saves some time.
5124 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Fixed JOIN command on client library. Wrong number of arguments
5127 used to crash the client.
5129 * Added silc_server_channel_has_global function to check whether
5130 channel has global users or not.
5132 * Added silc_server_channel_has_local function to check whether channel
5133 has locally connected clients on the channel.
5135 * The silc_server_remove_from_one_channel now checks whether the
5136 channel has global users or not after given client was removed from
5137 the channel. It also checks whether the channel has local clients
5138 on the channel anymore. If it does not have then the channel entry
5139 is removed as it is not needed anymore.
5141 * The silc_server_notify now checks on JOIN notify whether the joining
5142 client is one of locally connected or global. If it is global then
5143 the channel has now global users on the channel and that is marked
5144 to the channel entry. Also, it now saves the global client to
5145 global list who is joining and JOINs it to the channel. This is
5146 for normal server, that is.
5148 Changed silc_server_send_notify_on_channel,
5149 silc_server_packet_relay_to_channel and
5150 silc_server_packet_send_to_channel check if we are normal server
5151 and client has router set (ie. global client) do not send the
5152 message to that client, as it is already routed to our router.
5154 * Implemented LEAVE notify type handling in silc_server_notify
5157 * Tested LEAVE command in router environment successfully. Tested
5158 with two routers, two servers and two clients.
5162 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5164 * Implemented SIGNOFF notify type handling in silc_server_notify
5167 * silc_server_remove_id now removes the client entry from all channels
5168 it has joined and thusly sends SIGNOFF notify type.
5170 * Rewrote the NAMES list generation in server by removing two excess
5171 loops. The lists are created now inside one loop.
5173 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * silc_server_remove_channel_user checks now also global list
5176 for channel and client.
5178 * silc_server_new_channel_user checks now both local and global
5179 list for channel and client. Fixed a bug in client id decoding.
5180 Used to decode wrong buffer.
5182 * silc_server_channel_message checks now both local and global
5183 list for channel entry.
5185 * Tested channel joining (hence JOIN) in router environment
5186 successfully. Tested with two routers, two servers and two
5189 * Tested channel message sending in router environment successfully.
5191 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added silc_server_save_channel_key into server.[ch] to save the
5194 received channel key in Channel Key payload processing. It is
5195 also used in JOIN command reply handling.
5197 Equivalent function silc_client_save_channel_key added into
5198 client.[ch] into client library.
5200 * Changed JOIN command reply to send information whether the channel
5201 was created or not (is existing already) and the channel key
5202 payload. Changed protocol specs accordingly.
5204 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5205 the request was sent by ID and not by nickname. Crashed on
5208 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5211 now correctly save the received data.
5213 * silc_server_free_sock_user_data now notifies routers in the
5214 network about entities leaving the network.
5216 At the same time implemented functions silc_server_remove_id
5217 and silc_server_send_remove_id to receive and send REMOVE_ID
5218 packets. The packet is used to notify routers in the network
5219 about leaving entities. The ID removed will become invalid in
5222 * Added function silc_idlist_del_server into server. Removes and
5223 free's server entry from ID list.
5225 * silc_server_private_message function now checks, if we are router,
5226 that the destination ID really is valid ID, naturally.
5228 * In router when NEW_ID packet is received (for new client) the
5229 hash of the Client ID is saved in the ID Cache but the
5230 client->nickname is set to NULL, instead of putting the hash
5233 IDENTIFY command now also checks that client->nickname must be
5234 valid. If it is not if will request the data from the server who
5235 owns the client. Added new function
5236 silc_server_command_identify_check.
5238 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5239 to set the command to already allocated Command Payload.
5241 * Tested private message sending in router environment with two
5242 routers, two servers and two clients. Fixed minor bugs and now
5245 * Fixed segfault from client's NAMES command. Used to crash if
5248 * Forwarded packets must not be routed even if it is not destined
5249 to the receiver. Changed server code comply with this.
5251 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Added `require_reverse_mapping' boolean value to ServerParams
5254 structure. If TRUE (not default) the server will require that
5255 the connecting host has fully qualified domain name.
5257 If the reverse mapping is not required and hostname could not be
5258 found the IP address is used as hostname.
5260 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Implemented version string checking to both client and server.
5263 The check is incomplete currently due to the abnormal version
5264 strings used in development version of SILC.
5266 * Changed all command functions in server to use the new
5269 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Changed char *data to unsigned char *data in ID Cache system to
5272 support binary data as ID Cache data. Changed code to support
5273 binary data in lib/silccore/idcache.c.
5275 * Renamed silc_server_packet_relay_command_reply to
5276 silc_server_command_reply as it is normal packet receiving
5277 function. Rewrote the function to accept command replys for
5278 servers and not only for clients.
5280 * Mark remote router always as registered server if we are connecting
5281 to it. Otherwise, commands sent by the router to us are ignored.
5283 * All ID List find routines now returns the ID Cache Entry pointer
5284 as well if requested.
5286 * WHOIS command works now in router environment, tested with two
5287 routers, two servers and two clients.
5289 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5290 in router environment (as it is almost equivalent to WHOIS) but
5291 hasn't been tested thoroughly. Added new functions:
5293 silc_server_command_identify_parse
5294 silc_server_command_identify_send_reply
5295 silc_server_command_identify_from_client
5296 silc_server_command_identify_from_server
5298 * Disabled route cache adding because adding two different ID's with
5299 same IP replaces the old cache entry thus giving wrong route.
5300 The entry->router->connection is always the fastest route anyway
5301 so route cache may not be needed. Of course, new routes maybe
5302 established after receiving the ID when the entry->router->connection
5303 might not be anymore the most optimal.
5305 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Add route cache for received ID for fast routing.
5309 * Added silc_server_packet_route to route received packet on router
5310 that is not destined to us.
5312 * Renamed silc_server_get_route to silc_server_route_get.
5314 * Added id_string and id_string_len fields into SilcServer to
5315 include encoded ServerID for fast comparing without excess
5316 encoding of the ID's.
5318 * Cleaned up WHOIS command on server side. Added following static
5321 silc_server_command_whois_parse
5322 silc_server_command_whois_check
5323 silc_server_command_whois_send_reply
5324 silc_server_command_whois_from_client
5325 silc_server_command_whois_from_server
5327 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5328 arguments in command replies. All command functions should be
5329 updated to use this macro.
5331 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Minor typo fixes on command reply handling on server.
5335 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added silc_server_command_add_to_channel internal routine to add
5338 the client to the channel after router has created the channel and
5339 sent command reply to the server.
5341 * Added generic silc_server_send_command to send any command from
5344 * Use static buffer with ID rendering instead of duplicating data.
5346 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Fixed a channel user mode bug when joining to a channel server gave
5349 everybody channel founder rights, oops.
5351 * We mark ourselves as the router of the incoming server connection
5352 if we are router ourselves. This way we can check in some packet
5353 sending functions whether it is locally connected server. For
5354 incoming router connections we put NULL.
5356 * For router sending packets locally means now always sending the
5357 packet cell wide; to local clients and local servers. For normal
5358 server sending packet locally means sending it to only local
5361 * Fixed the JOIN command to really work in router environment. If the
5362 channel is created it is always created by the router. Router is
5363 also responsible of making the initial joining to the channel,
5364 sending JOIN notify to the sending server and distributing
5365 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5366 does not exist server doesn't do anything else but forward the
5367 command to the router which performs everything.
5369 * Added silc_server_send_channel_key function to send the Channel Key
5372 * Added silc_server_create_channel_key to create new channel key. The
5373 channel key is now re-generated everytime someone joins or leaves
5374 a channel, as protocol dictates. Note: channel->key_len is the
5377 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5380 packet_receive.[ch] to separate packet sending and receiving
5381 routines. The server.[ch] now includes everything else including
5382 actual packet processing (writing and reading data) and other
5385 Renamed silc_server_private_message_send_internal to
5386 silc_server_send_private_message. The routine is still though
5387 used only to relay private messages as server does not send
5388 private messages itself.
5390 Renamed silc_server_new_channel to silc_server_create_new_channel
5391 and added new function sicl_server_new_channel that handles the
5392 incoming New Channel packet. Added also new sending function
5393 silc_server_send_new_channel to send New Channel Payload.
5395 * Added new function silc_server_notify to process incoming notify
5396 packet to the server/router. Server may then relay the notify
5397 to clients if needed.
5399 * Added new function silc_server_new_channel_user to process incoming
5400 New Channel User packet. Router will redistribute the packet and
5401 send JOIN notify to its local clients and locally connected servers
5402 if needed. Normal server will send JOIN notify to its local client
5403 on same channel when received this packet. Added also corresponding
5404 sending function silc_server_send_new_channel_user to sent the
5407 * Added boolean route argument to send_notif_to_channel and
5408 packet_send_to_channel functions to attempt to route the packet
5409 if it is TRUE and send only locally if it is FALSE.
5411 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * silc_server_replace_id now broadcasts the received replace ID
5414 packet if it is not broadcast packet already. The router must
5415 broadcast to inform other routers about changed ID.
5417 * Added backpointer to server's router into SilcServer context in
5418 silcd/server_internal.h.
5420 * Fixed silc_server_packet_broadcast to send correct broadcast
5423 * The channel key is now distributed to the local client as soon
5424 as it is received from the router (in router environment) so that
5425 no other packet may be sent for the channel until client has
5428 * silc_server_remove_channel_user now broadcasts the received
5429 Remove Channel User packet if it is not broadcast packet already.
5430 The router must broadcast to inform other routers about removed
5433 * Added users field into SilcPacketContext that is a reference count
5434 of the context. One can increase the reference count by calling
5435 silc_packet_context_dup which is now changed to just increase the
5436 reference count instead of duplicating the data. The reference
5437 count is decresed by calling silc_packet_context_free that will
5438 free the data after the reference count hits zero.
5440 For now on the packet context and everything allocated into it
5441 (including the raw packet from network) must be freed by calling
5442 the new silc_packet_context_free function. Added also new function
5443 silc_packet_context_alloc that must be used now to allocate the
5444 context. This also means that if a routine is asynchronous from
5445 silc_[client/server]_packet_parse_type the packet context must
5446 be duplicated by calling silc_packet_context_dup. Otherwise it
5447 gets free'd after silc_[client/server]_packet_parse_type returns.
5448 Also, one must remember that if packet is duplicated then its
5449 reference count must be decresed by calling the free function as
5450 many times as it was duplicated.
5452 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5453 from both client and server.
5455 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Made joining to a channel working in router environment.
5459 * Cleaned up JOIN command on server side and create function
5460 silc_server_command_join_channel internal routine to make the
5463 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Changed silc_command_pending list to SilcDList. Also, added
5466 `ident' field to SilcServerCommandPending structure to identify
5467 the reply and to call correct callback.
5469 Added silc_server_command_pending_check function to replace the
5470 corresnponding macro. The silc_command_pending list is not
5473 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5474 to set identifier to previously allocated Command Payload. It
5475 is used to set identifier for command when resending Command
5478 * Added silc_command_payload_encode_payload to encode Command
5479 Payload buffer from SilcCommandPayload structure.
5481 * Added silc_argument_payload_encode_payload to encode Argument
5482 payload buffer from SilcArgumentPayload structure.
5484 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Changed WHOIS command to support router connection on server side.
5487 The whois request is always sent to router unless the server is
5488 standalone server. After server has received the reply from the
5489 router will it send the reply to the client.
5491 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5492 broadcast received broadcast packet. The function is used only
5493 by router. The broadcast packet is always sent to the router's
5496 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5497 render given ID to printable string, for log files for example.
5499 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Made basic router to router connections working. At least they
5502 can now connect to each other but nothing really works the way
5503 they are supposed - yet.
5505 * Added new initiator token to RouterConnection configuration
5506 file in silcd/serverconfig.[ch]. It is used to tell whether we
5507 are the initiator to the remote router or whether we'll expect
5508 the other end to connect.
5510 * Moved registering of listener task to silc_server_init, hence
5511 the server starts listenning as soon as it is run, even if it
5512 does not have connections to other routers. Let's see how well
5515 * Changed default connection retry timeouts for more suitable in
5518 * Removed cipher and such arguments from silc_idlist_add_client
5519 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5520 Added new function silc_idlist_add_data to add the keys and stuff
5523 * Added SilcIDListData structure and added it to SilcClientEntry
5524 and SilcServerEntry as their first field in the structure. This
5525 way we can explicitly cast the ID entries to the SilcIDListData
5526 structure and get common data for the entries. In past, we had
5527 to first check what type of connection it is and then cast it to
5528 correct ID entry type. Now, we can directly cast the opaque
5529 pointer to the SilcIDListData (no matter what ID entry it actually
5530 is) and get the data needed.
5532 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5535 in some circumstances even if threre were timeout tasks, though not
5536 IO tasks, but tasks anyway. Now fixed.
5538 * Defined SilcServerConnection structure to hold connection specific
5539 stuff about directly connected servers and routers. The definition
5540 is currently in silcd/server_internal.h. I thought about having
5541 a bit more important role fro this struct but for now it is used
5542 only when connecting to other server (or router actually).
5544 * Added connecting retry support in server when connecting to
5545 router(s). The retry feature implement exponential backoff
5546 algorithm. Also, added SilcServerParams structure to hold default
5547 parameters for server. For now, it include these retry settings
5548 and are hard coded. After server is moded to be as Silc Server
5549 Library this structure will be more important.
5551 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Changed client librarys channel->clients table to SilcList and
5554 changed code accordingly.
5556 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Changed client's channel table to SilcList and changed code
5559 accordingly. Also changed SilcChannelClientEntry to include back-
5560 pointer to the channel so that client entry can use that structure
5561 as list as well and we have fast cross-reference to the channel.
5562 This change dramatically decreased the complexity of channel
5563 handling with client entry and vice versa (removed one extra
5564 loop when searching for channel entry from many functions).
5566 * Changed server->sim from table to SilcDList and changed code
5569 * NAMES command can now be used from user interface. It will show
5570 the user list on the channel, neatly.
5572 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5573 Code now saves realname of the user if it becomes available.
5575 * Renamed configure.in to configure.in.pre and made ./prepare
5576 script to automatically add correct version string to
5577 configure.in which it creates from configure.in.pre.
5579 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * NAMES command reply now shows users mode with the nickname when
5584 * Moved silc_client_ch[u]mode[_char] functions from
5585 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5586 place sucks, they are utility functions and should be in some
5589 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5591 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5594 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added TRQ (efficient deque and list library) into lib/trq. This is
5599 a very good list library that is currently used in the SILC. Defined
5600 SilcList API over the library because I didn't like the API very
5601 much. See lib/trq/silclist.h for the API and examples of how to
5602 use the API. Fixed various places in the code to use the new
5603 SilcList API. The SilcList is meant for lists that has a structure
5604 already defined as a list. It is not suitable to add just some
5605 context to the list (in TRQ, the context is the list actually).
5607 So, I defined SilcDList that can be used for the purpose where
5608 predefined list structure does not exit. This can be used as
5609 such list. Now some context just can be added to the SilcDList.
5610 Currently this list is not used in the SILC just yet, though there
5611 are a lot places where this can replace dynamically allocated
5612 tables and I will fix these places, later, to use SilcDList.
5613 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5614 and use TRQ internally).
5616 Also fixed some annoying warning messages that the original TRQ
5617 code generated. Also minor changes to TRQ's Makefile.in.
5619 * Added support for querying by Client ID to both WHOIS and
5620 IDENTIFY commands into server, as required by the protocol.
5622 * Removed method function pointers from SilcBuffer structure. They
5623 weren't used to anything and just increased the context size for
5624 no good reason. This change also made silc_buffer_alloc and
5625 silc_buffer_free functions inline functions.
5627 * Disabled command flooding detection support until it's fixed so
5628 that it accepts commands in but does not execute them more than once
5631 * Added silc_net_localhost(), to return local hostname, into
5632 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5633 that must be initialized before calling silc_client_init.
5635 * Added new function: silc_server_send_notify_on_channels to send
5636 notify messages to all channels client has joined. It is assured
5637 that the message is sent only once per client.
5639 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5640 lib/silcutil/silcutil.[ch] as silc_format function. The new
5641 function is generic and is used by server as well, not only by
5642 the logging routines.
5644 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5645 the provided version string was not acceptable. Added new function:
5646 silc_ske_check_version into lib/silcske/silcske.h. The function
5647 must be implemented by the application (client or server) and it
5648 does not reside in the SKE library. The function checks the version
5649 string remote end sent.
5651 * Added back pointers (to opaque context and to SilcSocketConnection)
5652 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5654 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5655 duplicate packet context structure.
5657 * Changed `notify' client operation to send same arguments as client
5658 receives from server except for ID's. ID's are mapped to correct
5659 ID entry and that is returned. Also, if channel entry is not sent
5660 by server but the notify is for channel the channel entry is sent
5661 to application (otherwise application doesn't know that it is for
5662 channel (library gets it from packet's Destination ID)).
5664 * Added silc_client_remove_from_channels into client library to
5665 remove a client from all channels it has joined to. Used when
5666 received SIGNOFF notify from server. Added also new function
5667 silc_client_replace_from_channels to replace old ID entry with
5668 new ID entry on all channels. Used when received NICK_CHANGE
5671 * Fixed ID Cache list handling in silc_idlist_get_client in
5672 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5673 to get (or query) client by ID.
5675 * Updated TODO list.
5677 * Added connection authentication status message defined by the
5678 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5679 support for these into the code in client and server side.
5681 * Added generic function silc_client_send_command to send any command
5682 with variable argument list. Application should use this function
5683 to send commands if the command functions provided by the library
5684 does not suite for the application's user interface needs.
5686 * Added new `failure' client operation. Application is notified about
5687 received failure packet if client is executing a protocol. In this
5688 case the protocol's execution has failed.
5690 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5691 is required by the protocol.
5693 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5694 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5697 * Added status flag to SilcSKE object to indicate realtime status
5698 of the SKE protocol.
5700 * Application receives now exactly same command reply arguments as
5701 the library receives from server. However, if ID is received the
5702 corresponding ID entry is returned to the application (eg. Client
5703 ID is mapped to correct SilcClientEntry entry and that is returned).
5704 Changed command_reply client operation due to this change.
5706 * Changed all ID's in commands and in command replys as ID Payloads.
5707 Change affected both client and server side codes.
5709 All ID's sent in SILC network (with execption of ID's in SILC
5710 Packet header) are sent in ID Payload to support variable length
5713 * Server now notifies nick changes and notifies all clients on
5714 the channels about the new nickname (about the new Client ID,
5717 * Implemented CMODE command to change channel modes. Supports all
5718 channel modes defined by the protocol specs except ban and invite
5719 lists. (Also, private channel key mode is supported but support for
5720 setting private channel key in client is missing, thus, this mode
5721 has no effect on client side (except that server requires that the
5722 client uses private channel key and normal channel traffic does not
5725 Also, invite mode works per se, but INVITE command does not work
5726 yet correctly, so you can set channel as invite only channel but
5727 inviting clients to the channel does not work (it is yet to be
5728 thought what's the best way to do it).
5730 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5731 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5732 Implemented CUMODE command to change user's mode on the channel.
5733 Supports all modes defined by the protocol specs.
5735 * Added NAMES command reply to return users modes on the channel.
5737 * Removed unnecessary and slow ciphers from lib/silccrypt.
5739 * Set SO_KEEPALIVE option to connection sockets by default.
5741 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5743 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5744 redefined the Notify Payload into protocol specs.
5746 * Added silc_id_payload_parse_id to get ID directly from raw
5749 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5752 accept searching by Client ID as well.
5754 * Added support for LEAVE and SIGNOFF notify types in client library.
5756 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5757 to parse ID Payload from raw data.
5759 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added flags parameter into silc_ske_assemble_security_properties
5762 function in lib/silcske/silcske.[ch].
5764 * Changed notify client operation to fit better for notify messages
5765 sent by server. The notify payload received from server is now
5766 passed to the application (after parsing it to SilcNotifyPayload).
5767 It is application's responsibility to retrieve the arguments
5768 from the payload and show the message the way it wants. The message
5769 sent by server is implementation specific.
5771 * Changed public keys to comply with the protocol specification.
5772 Old public keys are not supported anymore and are not compatible.
5774 * Removed nickname from Channel Payload as the latest draft removed
5775 it. The client must resolve the nickname from the NAMES command
5776 reply received when it joined the channel.
5778 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5780 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Fixed some errors in protocol specification drafts.
5784 * Created lib/silccore/silcnotify.c to implement Notify Payload
5785 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5786 generic payloads described by protocol specifications. The file
5787 includes implementations for ID Payload and Argument Payload.
5789 * Changed Command Payload implementation to use the new Argument
5790 Payload. Changed command_xxxx_payload to command_payload_xxxx
5791 to comply with SILC coding conventions.
5793 * Added suppport for Argument Payload handling in Notify Payload
5794 implementation as protocol requires it. Added the new support
5795 into server and client lib as well.
5797 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Added support for multiple nicknames on same channel. [n] is
5800 added locally to the nickname if there are more than one same
5801 nicknames on the channel.
5803 * Server now sends all nicknames that matched WHOIS request.
5804 Client also shows the list received from server.
5806 * Added TOPIC command to client side. User can now set and show
5807 current topic on channel.
5809 * Added MOTD command to client and server. Also, server sends the
5810 motd when client connects to the server.
5812 * Changed version strings to comply ISO 8601.
5814 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Fixed protocol error handling in client library. It should now
5817 cope even if the SKE fails for some reason.
5819 * Made new protocol specification drafts for submitting to IETF.
5821 * Implemented TOPIC command to server in silcd/command.c.
5823 * Added two new notify types into lib/silccore/silcnotify.h:
5824 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5825 notify nickname change and topic setting/change on a channel.
5827 * API change of command_reply operation in client library. The
5828 application gets now the status type received from server as well.
5830 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5834 * Cras fixed and optimized the packet handling even further and
5835 it should work now. Minor change to the prototype of function
5836 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5838 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Added new function into lib/silcutil/silcschedule.[ch]:
5841 silc_schedule_with_fd to select() a specified fd. The function
5842 returns after timeout expires or data arrives or goes. The
5843 function is used by packet routines to wait that all data is
5844 received from network.
5846 * Fixed data reading from network in lib/silccore/silcpacket.c.
5847 The code now assures that all data is read from the fd and then
5848 continues packet processing. This was a bug fix since the code
5849 used to drop some data in some circumstances.
5851 * Added new function into lib/silcclient/client.[ch]:
5852 silc_client_start_key_exchange to start key exchange after
5853 connection has been established to server. The code internally
5854 now uses this funtion but its main purpose was to provide it
5855 for applications that perform their own connecting. After
5856 application has created a connection it merely calls this
5857 function to start the key exchange between client and server.
5858 The library takes care of everything else after that.
5860 Updated also lib/silcclient/README to explain the usage of
5863 * Do not send to application information that connection has
5864 been established. Application gets notified it by connect
5867 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * Applied cras's patch to add silc_schedule_one function. The
5870 function runs scheduler once and returns.
5872 * Fixed the scheduler after cras messed it up. The timeout
5873 handling works now as it's supposed to work.
5875 * Added into lib/silccore/ silcnotify.h to include notify
5876 message types support. Changed silc_server_send_notify*
5877 functions, in server.[ch], to support those new notify types.
5878 Added the support for the notify types into client library,
5879 as well. Added new notify client operation into ops.h in
5882 * Changed silc_server_packet_send_to_channel to send normal
5883 packets instead of just channel message packets. The function
5884 is now used to send the notify packets to channels. It is not
5885 used to send channel message packets anymore, as server never
5888 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5889 va_arg()s as it seems to require it nowadays. I guess, if SILC
5890 is compiled with older va_arg() the new code should work anyway.
5892 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Splitted core library. Core library (lib/silccore) includes
5895 now only SILC protocol specific core (and common) components.
5896 Created new utility library (lib/silcutil) that includes more
5897 generic purpose stuff. The stuff for util library was taken
5898 from the old core library. This was minor and easy split.
5900 * Created SILC Client Library (lib/silcclient) that includes
5901 implementation of the SILC client without user interface. This
5902 was major move from silc/ directory. The code has been changed
5903 so that it is transparent towards the user interface. The
5904 silc/ directory includes now the same user interface as before
5905 and it uses the new client library. Read lib/silcclient/README.
5906 Basicly, the client library performs everything else related
5907 to SILC except user interface handling. Also, configuration
5908 files are considered to be part of user interface and library
5909 does not handle them.
5911 This change also changed a lot of structures, function naming etc.
5912 Most important change was that SilcClientWindow object was
5913 renamed to SilcClientConnection in the client library. Created
5914 also new file lib/silcclient/ops.h. Also added new files
5915 silc/local_command.[ch] and silc/client_ops.[ch].
5917 All these changes were made to make it easier for user interface
5918 designers to create what ever user interface for the SILC client
5921 It is also expected that the server will be moved to lib
5922 directory as well and SILC Server Library will be created;
5923 sometimes in the future.
5925 * Removed Local commands from lib/silccore/silccommand.h as
5926 they are application specific and new client library does not
5927 handle any of those anymore.
5929 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5930 old client implementation in silc/.
5932 * Added support for callback functions in SILC_LOG_* macros.
5933 Application can now set its own callbacks that will be called
5934 instead of using the default functions that will always print
5935 the debug messages to stderr (or stdout). Also, debugging can
5936 now be disabled by setting silc_debug to FALSE and re-enabled by
5937 setting it to TRUE. Note, that logging will still work even
5938 if debugging is disabled.
5940 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5941 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5942 silc_log_reset_debug_callbacks.
5944 * To enable debugging in silc client one must give now -d
5945 option on command line.
5947 * Changed silc_schedule_init to automatically allocate task queues
5948 if they are not allocated before calling it.
5950 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Added GMP 3.1 into math library.
5954 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5957 a channel in SILC network. The packet is used by servers and
5958 routers to notify other routers that user has left a channel.
5959 This little feature was missing until now. Added the feature
5960 to protocol specification as well.
5962 Added functions: silc_server_send_remove_channel_user and
5963 silc_server_remove_channel_user into server.[ch].
5965 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5966 lib/silccore/silcpacket.h. However, they are not implemented
5969 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Fixed joining to a channel and sending channel messages
5972 between server and router. The channel message sending should
5973 now work inside a cell.
5975 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Fixed the private message sending between server and router.
5978 The private message sending should now work inside a cell.
5980 * Added silc_server_replace_id into server.[ch] to replace
5981 existing ID in the SILC network.
5983 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5984 and silc_idlist_replace_server_id into idlist.[ch] in server.
5986 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Fixed the server to server connections. Server can again now
5989 connect to router. Router to router connections probably does
5992 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Added dynamic protocol registering support. Now protocols can
5995 registered and unregistered on the fly. Patch by cras.
5997 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added lib/contrib directory to hold routines that some platforms
6000 don't have but are needed by SILC.
6002 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6003 into lin/contrib to provide getopt() and getopt_long() for
6004 those who don't have it.
6006 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added AWAY command to client. When away message is set and
6009 client receives a private message packet the client automatically
6010 replies to the sender with the away message.
6012 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6013 bug seemed to be the cause of recent problems when compiling
6016 * Added version detection support to SKE protocol specification
6017 and added the new changes to the SKE implementation as well.
6018 There were other minor changes in the SKE protocol as well.
6020 Many changes in lib/silcske/silcske.[ch] and in
6021 lib/silcske/payload.[ch].
6023 * Added ^U functionality, clear input line. Patch from cras.
6025 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Mainly small bugfixes on core library. Fixed some debugging
6028 logging and buffer overflow in silclog.c.
6030 * Updated config.sub and config.guess on the distribution tree.
6032 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added command lagging support in server. Client may execute
6035 commands now only once in two seconds.
6037 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Optimized packet reception. MAC computation and checking is now
6040 also more optimized. A lot previously duplicated code is now
6041 used as generic by both client and server.
6043 * Fixed key pair generation in clientutil.c
6045 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added into lib/silccore/silcbufutil.[ch] new function;
6048 silc_buffer_realloc.
6050 * Moved generic packet sending/encryption functions to
6051 lib/silccore/silcpacket.[ch] from client and server. Some
6052 rewriting of the functions.
6054 * Moved all generic packet reception/decryption functions to
6055 lib/silccore/silcpacket.[ch] from client and server. The
6056 packet processing is now much cleaner in both client and server.
6057 These were major changes in both client and server.
6059 * Created many common functions in server to do packet sending.
6060 Previously code were duplicated a lot, this has been removed
6063 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Rewrote major parts of the ID cache system. Don't know
6066 whether it is better now or not but at least the API is more
6069 * Major rewrite on ID cache stuff on client because of the ID
6070 cache API changes. Added idlist.c to client.
6072 * Also major rewrite on ID cache stuff on server as well.
6073 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6074 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6075 in hand, instead they are all put into the ID cache system now.
6076 All server_idlist_* routines uses ID cache now instead of
6077 traversing its own lists (those lists does not exist anymore).
6078 SilcIDList though still exists. Also, SilcXXXEntry's are
6081 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Finally made the SKE implementation compliant to the protocol
6084 specification. All mp integers are now binary encoded as
6085 opposed being HEX encoded.
6087 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6090 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6091 functions: silc_[encode/decode]_pem. Also added function
6092 silc_encode_pem_file to PEM encode with newlines ('\n') for
6095 * SILC public keys are now encoded either PEM or binary. Same
6096 option is for private keys as well. By default private keys
6097 are binary encoded and public keys PEM encoded. Silly HEX
6098 encoding were removed.
6100 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6101 function to create fingerprints.
6103 * Fixed a bug in SHA1; does not change the original data anymore.
6105 * Partly implemented INFO command on client and server side.
6106 Fixed CLEAR command. Changes to SERVER command; show current
6107 server(s) when giving command without arguments. Added
6108 VERSION command to client.
6110 * Added check to server that unregistered connections cannot
6111 execute commands (unless it is specificly allowed).
6113 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Fixed screen refresh.
6117 * Fixed channel joining bug from client. On some circumstances
6118 client tried to join to a channel it had already joined.
6120 * Added public key verification process into client's protocol.c.
6121 The client now verifies the public key from user and saves
6122 it into ~./silc/serverkeys/ directory.
6124 Added into: clientutil.[ch]: silc_client_verify_server_key.
6126 * Changed SKE protocol's silc_ske_initiator_finish function
6127 to accept callback function that verifies the received public
6128 key. Removed old silc_ske_verify_public_key function.
6130 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6133 silc_pkcs_private_key[_data]_set.
6135 * Made the password and public authentication more cleaner in
6136 server's protocol.c.
6138 * Removed historic and obsolete protocol `channel_auth' from
6139 both client and server.
6141 * Removed wrong way of sending command status messages from
6142 server to client in server's command.c. The old way violated
6143 protocol specification.
6145 Changes to silccore/silccommand.[ch]: removed
6146 silc_command_encode_status_payload -> not needed anymore,
6147 changed silc_command_encode_payload_va to accept extra
6148 argument on variable argument list. The argument type must
6149 now be provided to the function. Also, added new function:
6150 silc_command_encode_reply_payload_va which is same as
6151 normal command_encode_payload_va except command status type
6152 is provided as extra argument.
6154 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6156 * Added ~./silc directory handling. The directory includes the
6157 public and private keys for the client.
6159 Added silc_client_check_silc_dir, silc_client_create_identifier
6160 and silc_client_load_keys.
6162 * Implemented SILC protocol compliant public key. Added public
6163 and private key saving to and loading from files.
6165 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6166 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6167 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6168 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6169 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6171 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6172 silc_pkcs_load_[public/private]_key.
6174 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Added silc_server_get_route (route.[ch]) to get connection
6177 data for the fastest route for given ID.
6179 * Implemented INVITE command on client and server. The command
6180 were re-defined in the SILC Protocol Specification and the
6181 implementation now complies with the specification.
6183 * Implemented PING command on client and server.
6185 * Implemented NAMES command on client and server. The server side
6186 supports currently only normal server not router server yet.
6187 Some changes to NAMES definition in SILC protocol specification.
6189 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * Implemented LEAVE command on client and server.
6193 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6194 again. This change was made to the protocol as well. Server
6195 should not violate the protocol specification anymore.
6197 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6200 was tested. SOCKS4 was not but should work anyway.
