3 * If client entry is deleted with active key agreement
4 session, abort the session.
6 The silc_client_abort_key_agreement now calls the completion
7 callback with new SILC_KEY_AGREEMENT_ABORTED status.
9 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
12 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
14 * Don't use __restrict in older GCC's. Affected file is
15 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
17 * silc_net_localhost now attempts to reverse lookup the
18 IP/hostname. Affected file lib/silcutil/silcnet.c.
20 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
21 command. It can be used to gain founder privileges at
22 the same time when joining the channel.
24 Defined that the SILC_NOTIFY_TYPE_KICKED send the
25 kicker's client ID as well. Updated protocol specs.
27 Defined that the server must send SILC_COMMAND_IDENTIFY
28 command reply with error status to client who sent
29 private message with invalid client ID.
31 Updated the protocol specification.
33 * Added silc_server_send_command_reply to send any
34 command reply. Affected file silcd/packet_send.[ch].
36 * Added silc_id_payload_encode_data to encode ID payload
37 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
39 * The server now send IDENTIFY command reply with error
40 status if client ID in private message is invalid. Affected
41 file silcd/packet_receive.c.
43 * Save the server key file with server's IP address in
44 the filename instead of hostname. The affected file is
45 irssi/src/silc/core/client_ops.c.
47 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
49 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
52 * Added libtool support for compiling shared objects in
53 lib/silcsim. Affected file configure.in.pre and

58 * Pid file configuration, and server's config file fixes
59 patch by toma. Updated CREDITS file.
61 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
63 * Fixed silc_client_channel_message to not try to decrypt
64 the message twice if it resolved the destination client
65 information. This could cause of dropping one channel
66 message. Affected file lib/silcclient/client_channel.c.
68 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
70 * Added silc_client_run_one into lib/silcclient/silcapi.h and
71 lib/silcclient/client.c. This function is used when the SILC
72 Client is run under some other scheduler, or event loop or
73 main loop. On GUI applications, for example this may be
74 desired to used to run the client under the GUI application's
75 main loop. Typically the GUI application would register an
76 idle task that calls this function multiple times in a second
77 to quickly process the SILC specific data.
79 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
81 * Fixed silc_server_drop() for dropping the supplementary
82 groups as well, this could cause a security hole on some
85 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>

94 * Fixed MOTD to return the MOTD file server name. Affected
97 * Added INFO command reply handling to the Irssi SILC Client.
98 Affected file irssi/src/silc/core/client_ops.c.
100 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Fixed the silc_idcache_list_* routines to really support
103 the dynamic list. Fixes a crash. Affected file is
104 lib/silccore/silcidcache.c.
106 * Fixed the LIST command reply to really call LIST command's
107 pending callbacks. Affected file silcd/command_reply.c.
109 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
111 * Update conn->local_entry->nickname after giving NICK
112 command. Affected file lib/silcclient/command.c.
114 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
116 * Added the [pid] option to the silcd configuration file
118 Affected files: serverconfig.[ch] and silcd.c

122 * Save fingerprint in WHOIS command reply in server.
123 Affected file silcd/command_reply.c.
125 * Fixed NICK commands pending callback registration.
126 Affected file lib/silcclient/command.c.
128 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Use ++server->cmd_ident when sending commands in server,
131 instead of random number. Affected file silcd/command.c.
133 * Fixed GETKEY command reply to call actually GETKEY pending
134 command callbacks. Affected file silcd/command_reply.c.
136 * A bit stricter check for nicknames. Check for same nickname
137 in NICK command also. Affected file silcd/command.c.
139 * Do not call INFO command everytime client ID changes, only
140 during first connecting. Affected file lib/silcclient/client.c.
142 * Set the new nickname only after successful command reply for
143 NICK command is returned by server. Affected file
144 lib/silcclient/command.c.
146 * Remove nicknames from nicklist during server_signoff notify.
147 Should fix /NAMES bit more. The affected file is
148 irssi/src/silc/core/silc-channels.c.
150 * Added `fingerprint' field to the SilcIDListData in the
151 silcd/idlist.h to hold the fingerprint of the client's
154 Send the fingerprint of the client's public key in WHOIS
157 Affected files silcd/command.c, and silcd/idlist.[ch].
159 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
160 create fingerprint from given data.
162 * Show the fingerprint of the client's public key in WHOIS.
163 Affected files irssi/src/module-formats.[ch] and
164 irssi/src/silc/core/client_ops.c.
166 * Format the multiple same nicknames also during JOIN and
167 NICK_CHANGE notifys. Affected file is
168 lib/silcclient/client_notify.c.
170 * Do not print error on screen for invalid private message
171 payload since it can come if someone is sending private
172 messages with wrong key. Affected file
173 lib/silccore/silcprivate.c.
175 * Fixed multiple concurrent /PING crash. Affected file
176 lib/silcclient/command.c.
178 * Changed the wrong ID encoding. All IP addresses must be
179 in MSB first order in encoded format. They were encoded
180 wrong and was in LSB format. Affected files are
181 silcd/serverid.c, lib/silcutil/silcutil.c.
183 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
185 * Call the `connect' client operation through the scheduler
186 in case of error. Affected file lib/silcclient/client.c.
188 * Call the `failure' client operation even if the error
189 occurred locally during a protocol. Affected file is
190 lib/silcclient/protocol.c.
192 * Added support of sending LIST command to router from normal
193 server. This way normal server can get list of all channels
194 in the network too. Fixed the channel list sending in the
195 server too. Affected files are silcd/command.c, and
196 silcd/command_reply.[ch].
198 * Added silc_server_update_channels_by_server and
199 silc_server_remove_channels_by_server. They are used during
200 disconnection of primary router and in backup router protocol.
201 Affected file silcd/server_util.[ch], silcd/server.c and
202 silcd/server_backup.c.
204 * Fixed channel adding to global list in IDENTIFY command
205 reply in server. Affected file silcd/command_reply.c.
207 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
209 * If the incoming packet type is REKEY or REKEY_DONE process
210 that packet always synchronously. Fixes yet another MAC
211 failed error on slow (dialup) connections. Affected file
212 lib/silcclient/client.c and silcd/server.c.
214 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
216 * Call check_version SKE callback for initiator too. Affected
217 file lib/silcske/silcske.c.
219 * Implemented fix for security hole found in the SKE that was
220 fixed in the specification few days back; the initiator's
221 public key is now added to the HASH value computation.
222 Added backwards support for the old way of doing it too, for
223 old clients and old servers. Affected file is
224 lib/silcske/silcske.c.
226 * Enabled mutual authentication by default in SKE. If initiator
227 is not providing mutual authentication the responder will
228 force it. This will provide the proof of posession of the
229 private key for responder. The affected files are
230 lib/silcclient/protocol.c and silcd/protocol.c.
232 * Do not cache anymore the server's public key during SKE.
233 We do mutual authentication so the proof of posession of
234 private key is done, and if the server is authenticated in
235 conn auth protocol with public key we must have the public
236 key already. Affected file silcd/protocol.c.
238 * Added new global debug variable: silc_debug_hexdump. If
239 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
240 file lib/silcutil/silclog.[ch].
242 * Fixed compilation warning due to char * -> const char *.
243 Affected files lib/silcutil/silcnet.h, and
244 lib/silccore/silcauth.[ch].
246 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Fixed CMODE command when new channel key was created. If
249 the creation failed the old key was removed. Next time giving
250 same command would crash the server since the old key was
251 freed already. Affected file silcd/command.c.
253 * Fixed the silc_server_announce_get_channels to not crash
254 on reconnect. Affected file silcd/server.c.
256 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
258 * Added silc_log_set_debug_string function to set a regex
259 string to match for debug output. Only the function names,
260 or filenames matching the given debug string is actually
261 printed. This way it is possible to filter out those debug
262 strings that user is not interested in.
264 Fixed a bug in silc_string_regexify.
266 Affected files lib/silcutil/silclog.[ch], and
267 lib/silcutil/unix/silcunixutil.c.
269 * Changed the -d options in both server and Irssi SILC client
270 to take the debug string as argument. Affected files
271 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
273 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
275 * Added silc_hash_babbleprint to create a Bubble Babble
276 Encoded fingerprint. The encoding is developed by Antti
277 Huima (draft-huima-babble-01.txt), and it creates human
278 readable strings out of binary data. Affected file
279 lib/silccrypt/silchash.[ch].
281 * Print the babble print now in addition of fingerprint as well
282 in Irssi SILC client. Affected files are
283 irssi/src/fe-common/silc/module-formats.[ch],
284 irssi/src/fe-common/silc/core/client_ops.c.
286 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
288 * Fixed a security problem found in SKE. The initiator's
289 public key too is now added to the HASH hash value creation
290 which is signed by the responder to create the SIGN value.
291 This will prevent anyone in the middle to lie to the responder
292 about the initiator's public key. If this is done now, the
293 man in the middle will get caught. Updated the protocol
296 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
298 * Better installation directory handling. Configure module
299 paths and other paths automatically to example_silc* files
300 in doc/. A patch by toma.
302 * Fixed compiler warning from MPI library, and from SILC RNG.
305 * Added SILC_SERVER_PID_FILE to define the pid file for server.
306 It can be configured with ./configure. A patch by toma.
308 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Find correct make to use in prepare-clean. A patch by
311 toma. Affected file prepare-clean.
313 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
315 * Added irssi variables use_auto_addr, auto_bind_ip,
316 auto_bind_port and auto_public_ip.
318 * Changed the interface for silc_client_send_key_agreement
319 in lib/silcclient/silcapi.h
323 irssi/src/silc/core/silc-core.c
325 lib/silcclient/silcapi.h
326 irssi/src/silc/core/silc-channels.c
327 lib/silcclient/client_keyagr.c
330 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
332 * Added silc_pkcs_public_key_compare to compare two
333 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
335 * Check that the client who set the founder mode on the
336 channel is the same client that is giving the founder
337 mode to itself. It is done by comparing the saved public
338 key (it is saved even in the authentication is passphrase).
339 Affected file silcd/command.c.
341 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
343 * Do not process packet for disconnected socket connection.
344 Affected file lib/silccore/silcpacket.c.
346 * Process the DISCONNECT packet through scheduler in the
347 client library. Affected file lib/silcclient/client.c.
349 * Fixed the silc_client_packet_parse to not to increase
350 the packet sequence number if the conn->sock and the
351 current socket connection is not same. This can happen
352 for example during key agreement when the conn includes
353 multiple socket connections (listeners). Affected file
354 lib/silcclient/client.c.
356 * The sender of the file transfer request now provides also
357 the pointer (listener) for the key exchange protocol. If
358 the listener cannot be created then it sends empty key
359 agreement and lets the receiver provide the listener.
361 Added `local_ip' and `local_port' arguments to the
362 silc_client_file_send. If they are provided they are used,
363 if not then it will attempt to find local IP address, if
364 not found or bind fails then the remote client will provide
367 Affected files are lib/silcclient/client_ftp.c and
368 lib/silcclient/silcapi.h.
370 * Extended the FILE SEND command to support defining the
371 local IP and port for key exchange listener. They are
372 optional. Affected file irssi/src/silc/core/silc-servers.c.
374 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
376 * Defined to WHOIS command reply the sending of fingerprint
377 of the client's public key (if the proof of posession of the
378 corresponding private key is verified by the server).
379 Updated to the protocol specification.
381 * Added support of receiving the client's public key's
382 fingerprint in command reply in client library. Affected
383 file is lib/silcclient/command_reply.c, and
384 lib/silcclient/idlist.[ch].
386 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Do not send over 128 chars long nickname to the server
389 in NICK command. Affected file lib/silcclient/command.c.
391 * Do not send over 256 chars long channel names to the server
392 in JOIN command. Affected file lib/silcclient/command.c.
394 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
396 * Assure that silc_server_close_connection cannot be called
397 twice for same socket context. Affected file is
400 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Send error message to application if opening file for
403 writing during file transfer fails. Affected file is
404 lib/silcclient/client_ftp.c.
406 Remove all file transfer sessions for a client that we're
407 removing from ID cache.
409 Affected file is lib/silcclient/client_ftp.c.
411 * Fixed silc_net_addr2bin to return correct address. Affected
412 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
414 * Fixed file transfer session removing on signoff notify.
415 Affected file irssi/src/silc/core/silc-servers.c.
417 * Added the SilcClientFileError to be returned in the monitor
418 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
419 Affected file lib/silcclient/silcapi.h.
421 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
423 * Fixed a crash in silc_client_ftp_free_sessions and
424 silc_client_ftp_session_free_client. Affected file
425 lib/silcclient/client_ftp.c.
427 * Added `disabled' field in the SilcChannelEntry in the server
428 to indicate if the server entry is disabled. Affected file
429 silcd/idlist.h, silcd/command[_reply].c.
431 * SILC server adds now /var/run/silcd.pid everytime it is
432 started. Affected file silcd/silcd.c.
434 * Added silc_server_packet_send_clients to send a packet to
435 the provided table of client entries. Affected file
436 silcd/packet_send.[ch].
438 * Fixed a crash in client resolving in client_prvmsg.c in
439 client library. Affected file lib/silcclient/client_prvmsg.c.
441 * Do not actually remove the client directly from ID cache
442 during SERVER_SIGNOFF, but invalidate it. This way we
443 preserve the WHOWAS info for the client. Affected file
446 * Fixed SERVER_SIGNOFF notify handling in the server. The
447 server is now able to process incoming SERVER_SIGNOFF notify
448 for a server that it doesn't even know about. It will remove
449 the clients provided in the notify. Affected file
450 silcd/packet_receive.c.
452 * Check for partial packet in data queue after every packet that
453 was found from the queue. Return and wait for more data if
454 there is partial data in queue. Affected file is
455 lib/silccore/silcpacket.c.
457 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

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

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

559 SEND, RECEIVE, SHOW and CLOSE. Affected files
560 irssi/src/silc/core/client_ops.c,
561 irssi/src/silc/core/silc-server.[ch].
563 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Relay the SILC_PACKET_FTP in the server. Affected files
566 silcd/server.c and silcd/packet_receive.c.
568 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
570 * Renamed silc_file_read and silc_file_write to functions
571 silc_file_readfile and silc_file_writefile. Added function
572 silc_file_open and silc_file_close. Affected files
573 lib/silcutil/silcutil.[ch].
575 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
577 * Resolve the client info when received private message or
578 channel message for a client which nickname we don't know.
579 Affected files lib/silcclient/client_prvmsg.c and
580 lib/silcclient/client_channel.c.
582 * Do not crash in /KEY if client is not connected. Affected
583 file irssi/src/silc/core/silc-channels.c.
585 * Added SilcClientStatus field to the SilcClientEntry in the
586 lib/silcclient/idlist.h.
588 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
589 is incomplete and is being resolved, it won't be resolved
592 Make sure also that USERS command reply does not resolve
593 twice information. Affected file is
594 lib/silcclient/command_reply.c.
596 Make sure that silc_client_get_clients_by_list does not
597 resolve twice same information.
599 * Check for valid client->id in the silc_server_free_client_data.
600 Affected file silcd/server.c.
602 * Fixed /GETKEY nick@server not to crash if the server entry
603 is not found. Affected file lib/silcclient/command.c.
605 * Fixed the silc_server_check_cmode_rights to check the
606 requested modes correctly. Affected file silcd/command.c.
608 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Better checks for non-printable chars in nick added.
611 Affected file silcd/command.c.
613 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
615 * Call the silc_server_udpate_servers_by_server in the
616 primary router that comes back online in the backup resuming
617 protocol. Otherwise it routes packets wrong. Affected file
618 silcd/server_util.[ch], silcd/server_backup.c.
620 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
622 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
623 lib/silcutil/silcbuffmt.[ch].
625 * Redefined the SILC packet header to include the padding
626 length. Affected file lib/silccore/silcpacket.[ch].
628 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
629 length for maximum padding up to 128 bytes). Affected
630 file lib/silccore/silcpacket.h.
632 * Removed all backwards support for old 0.5.x MAC thingies.
633 The SILC packet header change makes it impossible to be
634 backwards compatible.
636 * Send the ENDING packet with timeout in the backup resuming
637 protocol. This is to assure that all routers has connected
638 to the primary router. Affected file silcd/server_backup.c.
640 * Changed the RNG to take the first IV from random data. It
641 used to take it from zero actually. Changed the RNG also
642 to use /dev/urandom during session. /dev/random is used
643 in initialization. Affected file lib/silccrypt/silcrng.[ch].
645 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Changed the SILC packet header to have the first two bytes
648 (the packet length) encrypted. Affected files aroung the
649 code tree, lib/silccore/silcpacket.[ch]. Removed the
650 SilcPacketCheckDecrypt callback. It is not needed anymore
651 since the silc_packet_receive_process will determine now
652 whether the packet is normal or special.
654 * Implemented the unidirectional MAC keys. Affected files
655 lib/silcske/silcske.c, silcd/protocol.c and
656 lib/silcclient/protocol.c.
658 * Implemented the packet sequence number to the MAC computation.
659 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
660 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
661 lib/silcclient/protocol.c.
663 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Allow backup router to announce servers. All servers
666 announced by backup router are added to the global list
667 automatically. Update hte server's socket to our primary
668 router also when backup router announces a server.
669 Affected file silcd/packet_receive.c.
671 * Do not update the client->router in the function
672 silc_server_udpate_clients_by_server if the client is on
673 global list. We might fail to find any specific server
674 for locally connected clients and local cell clients. They
675 should still use the `from' and not `to' as client->router.
676 This fixes backup router resuming protocol. Affected file
679 * Decrease channel statistics count only if the channel
680 deletion worked. Affected files are silcd/server.c and
683 * Added silc_server_update_servers_by_server to update origin
684 of all server entries. Used during backup router protocol.
685 Affected files silcd/server_util.[ch], silcd/server.c. and
686 silcd/backup_router.c.
688 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
689 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
690 silc_hmac_get_hash and silc_hmac_get_name. Affected file
691 lib/silccrypt/silchmac.c.
693 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Assure that router cannot reroute the same channel message
696 to the sender. Affected file silcd/packet_receive.c.
698 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Made better checks that the channel message is not sent
701 to the router it came from. Affected file is
702 silcd/packet_send.c. Fixed memory leak too.
704 * Announce informations for incoming router connection, but
705 only after checking if it is replaced by backup router.
706 Affected file silcd/packet_receive.c.
708 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Fixed the backup resuming protocol to work in multiple
711 router environment. Affected file silcd/server_backup.c.
713 * Route packet only to one router in the function
714 silc_server_packet_send_to_channel. Affected file is
717 * Fixed silc_server_send_notify_dest to set the broadcast
718 flag. Fixed the silc_server_send_notify_topic to actually
719 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
720 Affected file silcd/packet_send.c.
722 * Changed the SFTP Filesystem interface. Changed the
723 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
724 the filesystem operation function. The SilcSFTPFilesystem
725 is now a context that is allocated by all filesystem allocation
726 functions and it already includes the operations structure
727 and filesystem specific context. It is given as argument
728 now to the silc_sftp_server_start. This made the interface
729 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
730 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
732 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
734 * Changed the backup router adding and getting interfaces
735 in the server. The router that will be replaced by the
736 specified backup router is now sent as argument. Affected
737 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
740 * Added silc_net_addr2bin_ne to return the binary form of
741 the IP address in network byte order. Affected files
742 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
744 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
746 * Check for existing server ID in silc_server_new_server
747 and in silc_server_connect_to_router_final and remove the
748 old entry if it exists. Affected file silcd/packet_receive.c,
751 * Send the channel message always to only one router, either
752 in upstream or downstream. Affected file is
755 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Wrote the definition of the backup resuming protocol to the
758 protocol specification.
760 * Removed one redundant channel key generation from normal
761 server during joining procedure. Removed one redundant
762 channel key sending from server to router during joining
763 procedure. Affected file silcd/command.c.
765 * Made minor bugfixes to the backup router resuming protocol.
766 Affected file silcd/server_backup.c, server.c.
768 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Added --disable-asm configuration option. Affected files
771 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
774 * Implemented the backup resuming protocol that is used to
775 resume the primary router position in the cell after the
776 primary router comes back online. Affected files
777 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
778 and silcd/server_util.[ch].
780 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Sleep two (2) seconds after sending QUIT command to server.
783 Affected file lib/silcclient/command.c.
785 * Assure that if outgoing data buffer is pending do not force
786 send any data. Affected file silcd/packet_send.c.
788 * Assure that if outgoing data buffer is pending do not force
789 send any data. Affected file lib/silcclient/client.c.
791 * Implemented the backup router support when the primary router
792 goes down. The servers and routers can now use the backup
793 router as new primary router without loosing connectivity.
795 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
797 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
798 in the server to indicate disabled entry. All data read
799 from the connection will be ignored and no data is sent
800 for entry that is disabled. Affected files are
801 silcd/idlist.h, silcd/server.c.
803 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Created SFTP client and server test programs in the
806 lib/silcsftp/tests directory.
808 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
810 * Implemented memory filesystem (virtual filesystem) for
811 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
814 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Implemented the SFTP (SSH File Transfer Protocol) to the
817 lib/silcsftp. It includes SFTP client and SFTP server
820 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
822 * Moved lib/silccore/silcprotocol.[ch] to the
823 lib/silcutil library.
825 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
826 take variable argument list pointer as argument. Affected
827 file lib/silcutil/silcbuffmt.[ch].
829 * Added silc_buffer_set function that is used to set data
830 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
831 Affected file lib/silcutil/silcbuffer.h.
833 * Changed various routines in the core library to use the new
834 silc_buffer_set instead of allocating new buffer only for
837 * Added 64-bit value formatting and unformatting support to the
838 silc_buffer_[un]format routines. Affected file is
839 lib/silcutil/silcbuffmt.[ch].
841 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
842 to includes/bitmove.h.
844 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Fixed channel user mode saving in client library. Affected
847 file lib/silcclient/command[_reply].c.
849 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Defined the file transfer to the SILC Protocol. Added
852 new packet type SILC_PACKET_FTP and defined File Transfer
853 Payload. The mandatory file transfer protocol is SFTP
854 (SSH File Transfer Protocol). Affected file in addition
855 of the internet draft is lib/silccore/silcpacket.h.
857 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
858 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
859 is used as part of backup router protocol when the primary
860 router of the cell is back online and wishes to resume
861 the position as primary router.
863 * Redefined the MAC generation keys in the protocol. The
864 same key is not used anymore in both direction. Both
865 direction will now use different keys for sending and
866 receiving. This fixes a potential security flaw. This
867 change causes incompatibilities in the protocol.
869 * Redefined also the MAC computation from the packet.
870 An packet sequence number is now added to the MAC
871 computation. This prevents possible replay attacks against
872 the protocol. This change too causes incompatibilities
875 Added `sequence' field to the SilcPacketContext to hold
876 the current sequence number for the packet.
878 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Added `created' field to the SilcIDListData in the file
881 silcd/idlist.h to indicate the time when the entry was
884 * Added `created' field to the SilcChannelEntry too. Affected
887 * Added `creation_time' aguments to all the announcement functions
888 in the server. If it is provided then only the entries that
889 was created after the provided time frame are actually
890 announced. Affected file silcd/server.[ch].
892 * The protocol says that the Channel ID's IP address must be
893 based on the router's IP address. Added check for this in
894 the silc_server_new_channel when processing incoming New Channel
895 Payload. Affected file silcd/packet_receive.c.
897 * Print out the correct version with --version in SILC client.
898 Affected file irssi/src/silc/core/silc-core.c.
900 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
902 * Fixed WHOWAS command to check for completnes of the client
903 entry always, not just when the command is coming from client.
904 Affected file silcd/command.c.
906 * Added new function silc_server_packet_queue_purge to purge the
907 outgoing data queue to the network. After the function returns
908 it is guaranteed that the outgoing packet queue is empty.
909 Affected file silcd/packet_send.[ch].
911 * Purge the outgoing packet queue in the rekey protocol's final
912 callback to assure that all rekey packets go to the network
913 before quitting the protocol. Affected file silcd/server.c.
915 * Added silc_client_packet_queue_parse as similar function as
916 in server to the client library. The affected file is
917 lib/silcclient/client.c.
919 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Splitted silcd/server.c and created silcd/server_util.[ch]
922 for utility functions.
924 * Added new socket flag SILC_SF_DISABLED to indicate that the
925 connection is open but nothing can be sent to or received from
926 the connection. Affected file lib/silcutil/silsockconn.[ch].
927 The checking for disabled socket is checked in the low level
928 silc_socket_write and silc_socket_read functions.
930 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Allow only nicknames and channel names that fits into the
933 7-bit unsigned char ASCII set. Affected file silcd/command.c.
935 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
937 * When processing JOIN command reply in server check that if
938 the channel exists in our global list we'll move it the local
939 list. Affected file silcd/command_reply.c.
941 * Fixed the check whether client is joined on the channel already
942 in JOIN command. Affected file lib/silcclient/command.c.
944 * Fixed the JOIN command reply to check whether the channel
945 already exists. Affected file lib/silcclient/command_reply.c.
947 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
949 * Added silc_ske_status_string to map the SKE error numbers
950 to readable strings. The affected files are
951 lib/silcske/silcske[_status].[ch].
953 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Do not show the private channels on the WHOIS channel list
956 as it is not allowed by the protocol. The affected file is
959 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Assure that the packet length digged from the actual packet
962 is something sensible in the silc_packet_decrypt_rest_special
963 in lib/silccrypt/silcpacket.c.
965 * Free and NULL the allocated pointer in silc_hmac_alloc if
966 the HMAC allocation fails. The affected file is
967 lib/silccrypt/silchmac.c.
969 * Print the selected security properties to the log files in
970 the server. Affected file silcd/protocol.c.
972 * Add SKE's reference counter even if calling the completion
973 callback manually. Otherwise it goes negative, although it
974 does not cause any problems. The affected file is
975 lib/silcske/silcske.c.
977 * Remove the client entry with short timeout after giving the
978 KILL command. Affected file lib/silcclient/command.c.
980 * Fixed to send error reply in WHOIS and IDENTIFY commands in
981 case all found clients are already disconnected (WHOWAS would
982 found them) in the server. Affected file silcd/command.c.
984 * Update the last_receive (time of last data received) to be
985 updated only when received private or channel message so that
986 the idle time showed in WHOIS makes more sense.
988 * Added boolean field `valid' in to the SilcClientEntry in the
989 client library to indicate whether the entry is valid or not.
990 This fixes the nickname change bug on channel when changing
991 the nickname to be same than the old (like nick to Nick) the
992 nickname formatter doesn't set the new nick anymore to Nick@host.
993 Affected file lib/silcclient/idlist.[ch].
995 * Now actually fixed the nickname changing on disconnection.
996 Added new function silc_change_nick to the Irssi SILC Client.
997 Affected file irssi/src/silc/core/client_ops.c,
998 irssi/src/silc/core/silc-nicklist.[ch].
1000 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Check that the public key exists in the GETKEY command before
1003 trying to encode it. Affected file silcd/command.c.
1005 * Print some notifications on received public keys with GETKEY
1006 command in the Irssi SILC Client. Affected files are
1007 irssi/src/fe-common/silc/module-formats.[ch],
1008 irssi/src/silc/core/client_ops.c.
1010 * Use IDENTIFY command to resolve the server information in the
1011 GETKEY command instead of INFO command. Affected file
1012 lib/silcclient/command.c.
1014 * All command reply functions in the client library now calls
1015 the pending command reply callbacks even if an error has
1016 occurred. The server has done this a long time and now it was
1017 time to move the client library to this as well. Now all
1018 errors can be delivered back to the pending command reply
1019 callbacks if necessary. Affected files are
1020 lib/silcclient/command[_reply].[ch].
1022 * Change the nickname on disconnection back to the username
1023 because in reconnect the server will enforce it to it anyway.
1024 Affected file irssi/src/silc/core/silc-servers.c.
1026 * Fixed a config file parsing bug in the Irssi SILC client.
1027 Affected file irssi/src/silc/core/clientconfig.c.
1029 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * When printing the channel mode on JOIN, verify that the
1032 channel key and channel's HMAC are valid. Affected file
1033 irssi/src/silc/core/client_ops.c.
1035 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1038 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1039 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1041 * Removed channel key rekey task deleting from the function
1042 silc_server_save_channel_key. Affected file silcd/server.c.
1043 Added explicit timeout task context instead that is used to
1044 delete the task if we are registering a new task before the
1045 new task has elapsed.
1047 * When channel key rekey occurs the client library now saves
1048 the old channel key for a short period of time (10 seconds) and
1049 is able to use it in case some is still sending channel
1050 messages encrypted with the old key after the rekey. Affected
1051 file lib/silcclient/[idlist.h|client_channel.c].
1053 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Added check to the silc_server_new_id_real to not accept
1056 new ID if it is the sender's own ID. Affected file is
1057 silcd/packet_receive.c.
1059 * Assure that we do not announce ourself or the one we've
1060 sending our announcements when we're router and are announcing
1061 servers to our primary router. Affected file silcd/server.c.
1063 * Fixed silc_server_command_identify_check_client to assemble
1064 correct WHOIS packet. It send corrupted WHOIS packet and
1065 caused problem with router to router connections. Affected
1066 file silcd/command.c.
1068 Fixed also silc_server_command_whois_check the same way
1069 as for the IDENTIFY command.
1071 * Added new SilcIDListStatus to the server in the SilcIDListData
1072 structure. The status now includes the current status of
1073 the entry (like registered, resolved etc.). Affected file
1074 silcd/idlist.[ch]. Defined a bunch of different status types
1075 as well. This replaced the old boolean registered field as well.
1077 Added resolve_cmd_ident field to the SilcClientEntry structure
1078 too so that if the entry is for example being resolved so
1079 another command may attach to the same pending command reply
1080 without requiring to resolve the same entry again. This concept
1081 should optimize the WHOIS and the IDENTIFY resolving under
1082 heavy load by taking away unnecessary resolving for entries
1083 that are being resolved already.
1085 Added support for adding multiple pending commands for one
1086 command idenfier. Affected file silcd/command[_reply].[ch].
1088 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1089 before deleting the data. Otherwise the hash table will have
1090 freed data in comparison functions. Affected file is
1091 silcd/command_reply.c.
1093 * Fixed silc_idlist_replace_client_id to add the new entry to
1094 the cache with NULL nickname. Otherwise there will be invalid
1095 memory as the nickname after the nickname is freed. Affected
1096 file silcd/packet_receive.c.
1098 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1099 saved into wrong slots because the previous number of entries
1100 was not taken into account. Affected file silcd/idlist.c.
1101 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1103 * If we are router and we receive JOIN notify to a channel that
1104 does not have any users then notified client is marked as the
1105 channel founder, as it is it. The affected file is
1106 silcd/packet_receive.c
1108 * Added to the extended hash table API's table_del_*ext functions
1109 the destructor as argument too, so that the caller can decide
1110 which destructor to use or whether to use destructor at all.
1111 Affected file lib/silcutil/silchashtable.[ch].
1113 * Fixed ID Cache purging. It actually deleted the entries from
1114 the hash table after the data was freed. The hash table ended
1115 up comparing freed memory. The affected file is
1116 lib/silccore/silcidcache.c.
1118 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1120 * Fixed Irssi SILC client's KILL command's HELP syntax.
1122 * The USERS command now resolves the detailed user information
1123 if the userinfo field is missing. Affected file is
1124 lib/silcclient/command_reply.c.
1126 * Do not print error in silc_file_read if the read file does
1127 not exist. Just silently return NULL. Affected file is
1128 lib/silcutil/silcutil.c.
1130 * Fixed the silc_log_output to not wine about NULL filename
1131 and to not create some bogus " " filename. Affected file is
1132 lib/silcutil/silclog.c.
1134 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1136 * Fixed various printing bugs on the user interface in the
1137 Irssi SILC Client. Minor changes that were forgotten from
1140 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Fixed the configure.in.pre and the compilation and distribution
1143 environment to support the new autoconf 2.52. That version is
1144 now required to compile the CVS trunk.
1146 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1149 to generally parse user@fqdn format strings. Affected file
1150 lib/silcutil/silcutil.c.
1152 * Added nickname_format and nickname_force_format fields to the
1153 SilcClientParams structure. The first one defines the format
1154 for the nicknames that the library will enforce if the receives
1155 multiple same nicknames. The second one is boolean value and
1156 can be used to force the library to always enforce the format
1157 to the nicknames regardles whether there are multiple nicknames
1158 or not. This configurable formatting was employed to flexibly
1159 support accessing multiple nicknames from the user interface.
1160 The userinterface can now set the nicknames to what ever format
1161 they prefer. Affected file lib/silcclient/silcapi.h.
1163 Added function silc_client_nickname_format to the file
1164 lib/silcclient/idlist.c. It performs the nickname formatting.
1166 Added new field `hostname´ to the SilcClientEntry context.
1167 It holds the hostname of the client. Affected file is
1168 lib/silcclient/idlist.h.
1170 * Irssi SILC Client sets the nicknames in nick@hostn format.
1171 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1172 irssi/src/silc/core/silc-core.c.
1174 The WHOIS printing now also shows both the real nickname and
1175 the formatted nickname so that user knows how to access the
1176 user if there are multiple same nicknames cached. Affected
1177 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1178 printing formatting too to take the hostname now as a separate
1179 argument. The Affected file is
1180 irssi/src/fe-common/silc/modules-formats.[ch].
1182 * Changed the silc_client_get_clients_local to accept the formatted
1183 nickname as argument. It accepts the real nickname too but the
1184 formatted nickname can be used to find the true entry from
1185 multiple entries. Affected file lib/silcclient/silcapi.h and
1186 lib/silcclient/idlist.c.
1188 * Added nickname_format_parse field to the SilcClientParams.
1189 It is a callback function provided by the application to parse
1190 the nickname out of the formatted nickname string. The library
1191 calls it to get the nickname from the formatted string. Since
1192 the application generally knows better the format of the nickname
1193 string it parses it instead of the library, even though library
1194 encodes the formatted string. If the callback function is not
1195 provided then the library will use the string as is. The
1196 affected file is lib/silcclient/silcapi.h.
1198 * All the nickname strings passed to the client library in
1199 commands are now expected to be formatted nickname strings.
1200 If the command does not support the formatted nickname string
1201 it will assume that the sent string is the actual nickname.
1202 Affected file lib/silcclient/command.c.
1204 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Added public key authentication support to OPER and SILCOPER
1207 commands in the client library. Affected file is
1208 lib/silcclient/command.c.
1210 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Changed the get_auth_methdod client operation to be asynchronous.
1213 It can be async if the application resolves the authentication
1214 method from the server during the negotiation. Added new
1215 SilcGetAuthMeth completion callback that the application will
1216 call after resolving the authentication method.
1218 Added function silc_client_request_authentication_method that
1219 the application can use to resolve the authentication method
1220 from the server. Added also SilcConnectionAuthRequest callback
1221 that the library will call after the server has replied. The
1222 application can call this function if it does not know the
1223 current authentication method.
1225 Affected files are lib/silcclient/client.c and
1226 lib/silcclient/silcapi.h.
1228 * The Irssi SILC client now automatically resolves the authentication
1229 method incase any configuration information is not present (and
1230 currently there never is). The affected file is
1231 irssi/src/silc/core/client_ops.c.
1233 * Fixed public key authentication from the client library.
1234 Affected file lib/silcclient/protocol.c. Changed also the
1235 protocol specification about the public key authentication in
1236 the connection authentication protocol. The actual data to be
1237 signed is now computed with a hash function before signing.
1239 * Fixed the public key authentication from the server as well.
1240 Affected file silcd/protocol.c.
1242 * Removed the mlock()'s from the memory allocation routines.
1243 Affected file lib/silcutil/silcmemory.c. The ./configure does
1244 not check anymore for the mlock(). Affected file is
1247 * Fixed USERS command in server to allow the execution of the
1248 command for private and secret channels if the client sending
1249 the command is on the channel. Affected file silcd/command.c.
1251 * Fixed silc_client_get_clients_local to return the clients
1252 count correctly. It could return wrong value. Affected file
1253 lib/silcclient/idlist.c.
1255 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1258 types. The assembler optimizations seemed not to like 64-bit
1259 data types. The assmebler optimizations thus are now enabled
1260 also for BSD systems as opposed to only enable them for Linux.
1262 * Do not check for threads at all on BSD systems. Affected
1263 file configure.in.pre.
1265 * Removed -n and -h options from the Irssi SILC Client since
1266 they are not used in silc.
1268 * Fixed the prime generation to assure that the first digit
1269 of the generated random number is not zero since our conversion
1270 routines does not like number strings that starts with zero
1271 digit. If zero digit is seen the random number is regenerated.
1272 This caused some corrupted RSA keys when the zero first digit
1273 was met. Affected file lib/silcmath/silcprimegen.c.
1275 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Fixed WIN32 configuration in the ./configure script.
1278 Fixed to include xti.h on environments that has it.
1279 Patches by Carsten Ilchmann and andrew.
1281 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Changed the silc_id_create_client_id to be collision
1284 resistant. It is now assured that there cannot be created
1285 two same client ID's. I suspect that some weird bugs in
1286 the server were actually caused by duplicate Client IDs.
1287 Affected file silcd/serverid.[ch]. A router receiving
1288 new ID now also assures and informs the sending server
1289 if the ID caused collision.
1291 * Changed the silc_id_create_channel_id to also assure that
1292 there are no collisions.
1294 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1296 * Statement about ignoring the Mutual Authentication flag when
1297 performing rekey with PFS was a bit misleading. It is ignored
1298 if it was set in the initial negotiation, it cannot be even
1299 set in the rekey. Fixed in the ke-auth draft. Started the
1300 new versions of the protocol drafts in the doc/.
1302 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Fixed a bug in silc_client_command_identify_save when saving
1305 new channel information. The channel name was no duplicated
1306 and caused crash on exit. Affected file is
1307 lib/silcclient/command_reply.c.
1309 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Fixed the getkey command handling in the server. Send just
1312 empty OK reply to the sender if the key could not be fetched
1313 (but everything else was ok, like the key just was not available).
1314 Changed the public key parameter to optional in the protocol
1315 specs so that empty OK reply can be sent. Affected file
1318 Added a message to Irssi SILC client to tell to user if the
1319 server did not return a public key.
1321 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Fixed a channel key regeneration bug. It registered new
1324 timeout tasks exponentially until all system resources were
1325 used. Affected file silcd/server.c.
1327 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1329 * Added the SILC Document generator to the scripts/silcdoc.
1330 It can be used to generate the Toolkit Reference Manual out
1331 of the source tree. Internally it will also use the RoboDoc
1332 generator now imported in util/robodoc.
1334 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1336 * Added couple of return's in rekey protocol if error orccurred
1337 during the protocol. The execution must be terminated.
1338 Affected file silcd/protocol.c. Also, terminate the protocol
1339 always with timeout.
1341 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1343 * The client's Client ID was created initally from the wrong
1344 nickname (it could have been in format nick@host) in the
1345 silc_server_new_client. Affected file silcd/packet_receive.c
1347 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * Added some SILC_LOG_ERROR's to various error conditions
1350 if client could not be added to ID cache. Affected files
1351 silcd/packet_receive.c and silcd/server.c.
1353 * When client's sock->user_data is freed, NULL also the
1354 client->router and client->connection pointers. Added check
1355 for these pointers being NULL to various places around the
1356 code. Affected file silcd/server.c.
1358 * Added client->data.registered == TRUE checks to various
1359 places around the code to assure that unregistered client's
1360 are not handled when it is not allowed. Affected file
1363 * Added `bool registered' fields to all
1364 silc_idlist_[server|client]_get_* routines to indicate whether
1365 the fetched client needs to be registered or not. Affected
1366 file silcd/idlist.[ch].
1368 * Add your own entry as registered to the ID cache in the
1369 server. Affected file server.c.
1371 * Fixed a bug in silc_server_new_server. The SilcServer was
1372 set as the new server's context instead of SilcServerEntry.
1373 This naturally caused some weird bugs.
1375 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Do not delete the channel rekey task when adding it
1378 for in silc_server_create_channel_key.
1380 * Changed the silc_server_create_channel_key to return
1381 TRUE or FALSE to indicate the success of the channel key
1384 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Fixed MSVC++ project files and added missing files to
1387 Makefiles under win32/.
1389 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Do not add TCP_NODELAY flag if the operating system
1392 does not have it defined. Affected files are
1393 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1395 * Fixed buffer overflow from Irssi SILC Client. Affected
1396 file irssi/src/fe-common/core/themes.c.
1398 * Fixed double free in client library in the file
1399 lib/silcclient/client.c when disconnecting from server.
1401 * Applied double free patch from cras to Irssi SILC client.
1402 Affected files irssi/src/core/[modules/expandos].c
1404 * Fixed the disconnection handling to Irssi SILC Client.
1405 The application must call silc_client_close_connection
1406 in ops->connect client operation in case of failure of
1407 the connection. Affected file is
1408 irssi/src/silc/core/client_ops.c.
1410 * Do not set sock->protocol to NULL in the function
1411 silc_client_close_connection after executing the protocol's
1412 final callback since the sock might not be valid anymore.
1413 Affected file lib/silcclient/client.c.
1415 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Do not enable SILC_THREADS if the linking with libpthread
1418 did not happen. Affected file configure.in.pre.
1420 * Added notion to protocol specification that server must
1421 verify the sent authentication payload with CMODE when
1422 setting the channel founder key. Implemented it to the
1423 server. Affected file silcd/command.c.
1425 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added _EXTRA_DIST SILC distribution variable to the
1428 distributions file. It is used to conditionally add extra
1429 files or directories to the specific distribution. Affected
1430 files ./prepare, Makefile.am.pre and distributions.
1432 Removed the `_' from the start of the distribution names.
1435 * Added README.WIN32 for instructions to compile the Toolkit
1438 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Fixed a double free in disconnection in the server. Affected
1441 file is silcd/server.c.
1443 * Fixed the lib/silcske/groups.c to work now also with GMP
1444 MP library. The string conversion did not work when using
1445 specific base and the base is indicated in the string as well.
1447 * Created win32/ directory which now includes MSVC++ specific
1448 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1449 It will appear only in the toolkit distribution
1451 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Changed the key material distribution function in case when
1454 the hash output is too short. The data is now concatenated
1455 a bit differently than it used to. Made the change to the
1456 SKE protocol specification.
1458 * Added better GMP detection to configure.in.pre. A patch
1461 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Fixed a minor bug in SKE that might cause some problem on
1464 some platforms. Affected file lib/silcske/silcske.c.
1466 * Added the cookie checking for initiator in the SKE. It checks
1467 that the responder returns the sent cookie unmodified. The
1468 affected file is lib/silcske/silcske.c. Added new SKE
1469 error type INVALID_COOKIE that can be sent during the
1470 negotiation. Fixed some memory leaks as well.
1472 * Added the "invalid cookie" error message to Irssi SILC client's
1475 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Added `task_max' field to the SilcClientParams to indicate
1478 the maximum tasks the scheduler can handle. If set to zero,
1479 default values are used. Affected file lib/silcclient/silcapi.h.
1481 * Fixed memory leaks in silc_client_close_connection. Affected
1482 file lib/silcclient/client.c.
1484 * Added silc_client_del_client_entry to client library to free
1485 all memory of given client entry. Affected file is
1486 lib/silcclient/idlist.[ch].
1488 * Added new functions silc_client_del_channel and
1489 silc_client_del_server to delete channel and server entries.
1490 Affected file lib/silcclient/[silcapi.h/idlist.c].
1492 * Removed silc_client_del_client_by_id from silcapi.h.
1494 * Fixed the INFO command to return the server's own info
1495 correctly when querying by Server ID. Affected file is
1498 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Removed the non-blocking settings in WIN32 code in the
1501 silc_sock_[read/write] and added SleepEx instead. Affected
1502 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1503 of input data is now checked with FIONREAD and ioctlsocket.
1505 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Call silc_schedule_task_del_by_context in the
1508 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1509 Affected file lib/silccore/silcprotocol.c.
1511 * Call silc_protocol_cancel for active protocols in the
1512 silc_server_close_connection if the funtion
1513 silc_server_free_sock_user_data has not been called.
1514 Affected file silcd/server.c.
1516 * Generic tasks cannot be deleted using the del_by_fd
1517 task deleting function since generic tasks does not match
1518 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1520 * Added a notion to SILCOPER help file that the SILCOPER works
1521 only on router server, not on normal server.
1523 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Added for WIN32 support for the new scheduler as well.
1526 Affected file lib/silcutil/win32/silcwin32schedule.c.
1528 * Fixed the SHA1 implementation to work on various platforms.
1530 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1533 API. It is part of the scheduler now. Everything else is
1534 as previously but some functions has changed their names.
1535 Checkout the lib/silcutil/silcschedule.h for the interface.
1536 Updated all applications to use the new interface. Affected
1537 files are lib/silcutil/silcschedule.[ch].
1539 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Found a bug in the SKE implementation. The HASH value,
1542 specified by the protocol, was not computed correctly. The
1543 public key of the responder was not added to the computation
1544 even though it is mandatory. Affected file lib/silcske/silcske.c.
1545 This unfortunately causes incompatibilities with older
1546 clients and servers.
1548 * Added WIN32 specific network init and uninit functions:
1549 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1550 the Winsock2. Affected file lib/silcutil/silcnet.h and
1551 lib/silcutil/win32/silcwin32net.c.
1553 * Set the socket always to nonblocking mode on WIN32 after
1554 reading data or writing data. Affected file is
1555 lib/silcutil/win32/silcwin32sockconn.c.
1557 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Fixed various compilation problems under WIN32. Affected
1560 files lib/silcutil/win32/silcwin32thread.c and
1561 lib/silcutil/win32/silcwin32schedule.c.
1563 * Removed all _internal.h #includes from public header
1564 files. Internal headers must never be included from
1567 Removed also the lib/silcske/payload_internal.h file.
1569 * All include files that may be needed (public and some others
1570 included by the public headers) by application developers are
1571 now copied to the ./includes directory. It does not copy any
1572 internal headers. Affected file Makefile.defines.pre and all
1573 Makefile.am's under lib/ and subdirs.
1575 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Do not change the ~/.silc directory's permissions automatically.
1578 Affected file irssi/src/silc/core/clientutil.c.
1580 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Do not cancel the protocol in silc_server_close_connection
1583 it might cause recursion. Now cancelled in the function
1584 silc_server_free_sock_user_data. Affected file silcd/server.c.
1586 * Fixed the silc_server_remove_clients_by_server to regenerate
1587 the channel keys correctly finally. Added also new function
1588 silc_server_remove_clients_channels to actually do it.
1589 Affected file silcd/server.c.
1591 * Fixed the silc_server_new_channel to not crash by giving
1592 wrong router to the new channel. Affected file is
1593 silcd/packet_receive.c.
1595 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1598 which is given as argument to the silc_client_alloc now.
1599 It can be used to configure the client and set various parameters
1600 that affect the function of the client.
1602 * The USERS command in server did not check whether the channel
1603 is private or secret. Affected file silcd/command.c.
1605 * Added new argument to the USERS command in protocol specification.
1606 The USERS command now can take the channel name as argument
1607 as well. Added support for this in client and server and
1608 updated the protocol specs.
1610 * Completed the GETKEY command in client. It can be now used
1611 to fetch also servers public key not only some clients.
1612 Affected files lib/silcclient/command[_reply].c.
1614 * Added silc_client_get_server to return server entry by the
1615 server name. Affected files lib/silcclient/silcapi.h and
1618 * Redefined the IDENTIFY command in protocol specification to be
1619 more generic. It now can be used to query information about
1620 any entity in the SILC Network, including clients, servers and
1621 channels. The query may be based either the entity's name
1622 or the ID. Added support for this in both client and server.
1624 Affected files silcd/command.c and lib/silcclient/command.c
1625 and command_reply.c.
1627 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1628 the _from_client and _from_server functions. Affected file
1631 * Added silc_client_get_channel_by_id_resolve to the file
1632 lib/silcclient/silcapi.h to resolve channel information by
1633 its ID. Added also silc_client_get_channel_by_id that
1634 does not resolve it from the server.
1636 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Added SilcServerEntry context into the client library
1639 to represent one server. The INFO command now allocates
1640 these to save the resolved server info. For now on the
1641 client library will also keep information about servers,
1642 connected and resolved with INFO.
1644 The INFO command now allocates the SilcServerEntry context
1645 and saves the server info there. The COMMAND_REPLY in
1646 the INFO now returns the parameters to application in
1647 same order as defined in the protocol specification.
1649 The entries are cached in the client->server_cache.
1651 * The INFO command is now issued after received the Client ID
1652 from the server. Affected file lib/silcclient/client.c.
1654 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1655 to the application as the mode changer might be server.
1656 It is guaranteed that NULL is not returned anymore to the
1657 application. Affected file lib/silcclient/client_notify.c.
1659 The ID Type is now also passed to the application so that
1660 it can check whether the returned entry is SilcClientEntry
1663 Added new function silc_client_get_server_by_id to return
1664 the server entry by ID. Affected files are the
1665 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1667 * Do not create the channel in the Irssi SILC Client when issuing
1668 the JOIN command but when received the sucessful JOIN command
1669 reply. Otherwise the channel might get created even though we
1670 could not join it. The Affected file is
1671 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1673 * Fixed a channel joining bug in router. The router must also
1674 check the channel modes, invite and ban lists etc. when serving
1675 the JOIN command sent by normal server. Affected file is
1676 silcd/command.c. The router now resolves the client's
1677 information from the server who sent the JOIN command if it
1678 does not know it, and processes the JOIN command only after
1681 * Changed the SilcCommandCb to take new argument; void *context2.
1682 Affected file lib/silccore/silccommand.h
1684 The second argument in the command callbacks in the server now
1685 includes the SilcServerCommandReplyContext if the command was
1686 called as pending command callback from the command reply.
1687 Otherwise it is NULL. When called as pending the status of the
1688 command reply will be checked and if it was erronous the
1689 error will be sent to the original sender of the command.
1690 This way the client always receives the error messages even
1691 though the server was actually the one who received the error
1692 when it resent the command to router, for example. Affected
1693 files silcd/command[_reply].[ch].
1695 * Fixed sending WHOWAS command's error message to client if
1696 the requested client could not be found. It was missing.
1699 * Changed the CMODE and CUMODE commands reply arguments in the
1700 protocol specification. The Channel ID is now sent in both
1701 of the commands to identify the channel. Implemented this
1702 new feature to the client and server. Affected files
1703 lib/silcclient/command_reply.c and silcd/command.c.
1705 * Made better checks for invite and ban lists in the JOIN
1706 command in server. Affected file silcd/command.c.
1708 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * The server now performs the incoming host IP/DNS lookup
1711 using the silc_socket_host_lookup and thus does not block
1712 the server anymore. Affected file silcd/server.c.
1714 * Completed the multi-thread support for SILC Scheduler in
1715 the lib/silcutil/silcschedule.c.
1717 * Fixed the configure.in.pre to detect the pthread correctly
1720 * Fixed a deadlock in silc_task_queue_wakeup in the file
1721 lib/silcutil/silctask.c.
1723 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Added new function silc_schedule_wakeup that is used in
1726 multi-threaded environment to wakeup the main thread's
1727 schduler. It needs to be used when a thread adds a new task
1728 or removes a task from task queues. After waking up, the
1729 scheduler will detect the task queue changes. If threads
1730 support is not compiled in this function has no effect.
1731 Implemented the wakeup mechanism to both Unix and WIN32
1732 systems. Affected files are lib/silcutil/silcschedule.[ch],
1733 lib/silcutil/unix/silcunixschedule.c and the
1734 lib/silcutil/win32/silcwin32schedule.c.
1736 * Added new function silc_task_queue_wakeup to wakeup the
1737 scheduler by the specified task queue. Affected file
1738 lib/silcutil/silctask.[ch].
1740 * The silc_socket_host_lookup_start now wakes up the scheduler
1741 after adding the timeout task. Affected file is
1742 lib/silcutil/silcsockconn.c.
1744 * The silc_socket_host_lookup is synchronous now if the threads
1745 support is not compiled in. However, the callback is still
1746 called asyncronously through the scheduler, anyway. Affected
1747 file lib/silcutil/silcsockconn.c.
1749 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Added new function silc_socket_host_lookup to perform
1752 asynchronous IP and FQDN lookups for the socket connection.
1753 Affected files lib/silcutil/silcsockconn.[ch].
1755 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1758 that may or may not compile the mutex support in.
1760 Changed the silc_mutex_alloc interface. It allocates the
1761 mutex now to the sent pointer and returns TRUE or FALSE.
1763 Affected file lib/silcutil/silcmutex.h.
1765 * Wrote the SILC Task Queue interface to support multi-threads.
1766 Affected file lib/silcutil/silctask.[ch].
1768 * Wrote the SILC Scheduler to support multi-threads. Affected
1769 file lib/silcutil/silcschedule.c.
1771 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1774 in lib/silcutil/win32/.
1776 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Defined SILC Mutex API and SILC Thread API and implemented
1779 them for Unix. Affected files are
1780 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1781 lib/silcutil/unix/silcunixmutex.c and
1782 lib/silcutil/unix/silcunixthread.c.
1784 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Fixed the silc_server_remove_clients_by_server's channel
1787 key re-generation. The hash table handling was incorrect
1788 and would not work with many channels. Affected file is
1791 * Fixed some memory leaks around the server code.
1793 * Rewrote the silc_server_get_users_on_channel to support IPv6
1794 based Client ID's. Affected file silcd/server.c.
1796 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1797 specification. However, a separate document must be written
1798 to define the detailed signing procedure and the payload
1799 associated with the flag. Defined the flag to the
1800 lib/silccore/silcchannel.h as well.
1802 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Changed the dynamic tables to static size tables in the
1805 lib/silccrypt/silchmac.c.
1807 * Removed GCC dependencies from the code. A patch by cras.
1809 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Do not show the error "Error receiving packet bla bla"
1812 in server if it really was not an error (-2 means that reading
1813 is pending). Affected file silcd/server.c.
1815 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1817 * Fixed a possible crash in silc_server_remove_clients_by_server
1818 in silcd/server.c. Fixed there also some memory leaks.
1820 * Fixed the silc_idlist_replace_client_id. It could replace
1821 wrong key in the hash table. Affected file silcd/idlist.c.
1823 * Do not check whether there are global users on the channel
1824 if the channel->global_users is FALSE. Affected functions
1825 silc_server_remove_from_one_channel and
1826 silc_server_remove_from_channels in silcd/server.c. Also,
1827 do not check if the removed client is local as we can be
1828 sure that global client was not removed from the channel
1829 and checking for global users is not needed.
1831 * The silc_server_remove_clients_by_server now re-generates
1832 the channel keys correctly for those channels that had
1833 clients removed from them. Affected file silcd/server.c.
1835 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1837 * Found the reason of random crashes in the server. We weren't
1838 ignoring the SIGPIPE signal (which can be sent in write())
1839 and it crashed the server. Affected file silcd/silcd.c.
1841 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Assure that sock->user_data is not NULL in the function
1844 silc_server_packet_send in silcd/packet_send.c.
1846 * Disconnect the remote connection if it could not be added
1847 to any ID lists in the server. The affected file is
1850 * Check in silc_server_packet_send[_real/dest] that the
1851 socket is not disconnecting and ignore the data if it is.
1852 Affected file silcd/packet_send.c.
1854 * Define inline to __inline on native WIN32 compilation.
1855 Affected file includes/silcwin32.h.
1857 * Added some explicit type casts for inline code since MSVC
1858 require them. Affected files lib/silcutil/silcbuffer.h,
1859 lib/trq/silcdlist.h and lib/trq/silclist.h.
1861 * Print warning in log files from now on if the packet
1862 decryption fails. Affected file silcd/server.c.
1864 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Changed the `say' client operation's interface to accept
1867 new `type' argument to indicate the type of the message sent
1868 by the library. The application may filter the library's
1869 messages according the type. The affected file is the
1870 lib/silcclient/silcapi.h.
1872 * Added two new functions to lib/silcclient/silcapi.h:
1873 silc_client_del_client and silc_client_del_client_by_id.
1874 Affected file lib/silcclient/idlist.c.
1876 * Moved the clientincludes.h from includes/ to silc/ and
1877 serverincludes.h from includes/ to silcd/.
1879 * The modes for the CMODE and CUMODE are now passed as
1880 uint32 for application with COMMAND_REPLY. The affected
1881 file is lib/silcclient/command_reply.c.
1883 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * /WHOIS without arguments shows client's own information.
1886 Affected file lib/silcclient/command.c.
1888 * Changed PING to not accept any arguments. The specs
1889 says that client can ping only the connected server so
1890 requiring an argument is not needed. Affected file is
1891 lib/silcclient/command.c.
1893 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Fixed a fatal bug in private message sending and reception
1896 encryption and decryption when using private message keys.
1897 The implementation was incorrect and did not follow the
1898 specification. It causd that some of the message were
1899 lost since it did not use the sending and receiving keys
1900 as the protocol suggests. This has been fixed and will cause
1901 incompatibilities with older clients when sending private
1902 message encrypted with private message keys. Affected files
1903 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1904 and various other in Irssi SILC Client.
1906 Added `responder' boolean argument to the functions
1907 silc_client_add_private_message_key[_ske] to indicate when
1908 the key is added as responder or initiator of the key
1911 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Removed the silc_ske_check_version function and created
1914 a SilcSKECheckVersion callback. Added also a function
1915 silc_ske_set_callbacks that is now used to set all SKE
1916 callbacks. The callback functions are not given to
1917 the SKE functions anymore, but this function is used to
1920 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1922 * Added `silc_version' argument to the silc_client_alloc
1923 to define the version of the application for the library.
1924 The library will use the version string to compare it
1925 against the remote host's (usually a server) version
1926 string. Affected file lib/silcclient/silcapi.h
1928 * Added the KE protocol context to Key Agreement context
1929 in client library so that we can abort the SKE if it
1930 is in process when we get timeout. Affected file is
1931 lib/silcclient/client_keyagr.c.
1933 * Do not resolve the client ID forever if it returns in the
1934 first time that such client does not exist. This was done
1935 for example with private message. Affected file is
1936 lib/silcclient/client_prvmsg.c.
1938 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Do not add regex.h for WIN32. The affected file
1941 includes/silcincludes.h.
1943 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1944 not work yet 100%. It generates the DLL's automatically
1945 when compiling with --with-win32 under cygwin.
1947 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * lib/contrib/regex.c is not compiled on WIN32.
1951 * Added silc_net_get_socket_opt function to the
1952 lib/silcutil/silcnet.h.
1954 * Added includes/silcwin32.h for WIN32 specific includes
1957 * Do not use ptime structure or any of the posix process
1958 functions on WIN32 in lib/silccrypt/silrng.c.
1960 * Added silc_gettimeofday to provide generic function
1961 for struct timeval on all platforms. Added the function
1962 to lib/silcutil/silcutil.h.
1964 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1967 library as they clearly belong there. As a plus side we
1968 can make the actual socket connection routines platform
1971 Added also new generic function silc_socket_read and
1972 silc_socket_write (that used to be silc_packet_[read/write].
1973 The implementation of these are platform specific.
1975 * Added WIN32 specific routines of silc_socket_[read/write]
1976 to lib/silcutil/win32/silcwin32sockconn.c.
1978 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Added preliminary support for native WIN32 compilation under
1981 cygwin (using the -mno-cygwin option for GCC) to the
1982 ./configure.in.pre. The --with-win32 now prepares the
1983 compilation for native WIN32.
1985 * Rewrote the SILC Scheduler interface in the file
1986 lib/silcutil/silcschedule.h. The scheduler is now context
1987 based and does not have anymore any global static scheduler.
1988 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1989 and created lib/silcutil/win32 directory for WIN32 based
1992 * Added Unix specific network routines to the
1993 lib/silcutil/unix/silcunixnet.c and the old
1994 lib/silcutil/silcnet.c includes now only generic routines.
1996 Added WIN32 specific network routines to the
1997 lib/silcutil/win32/silcwin32net.c.
1999 * Added Unix specific utility functions from the
2000 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2002 * Added WIN32 SILC Scheduler to the file
2003 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2006 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Do not handle JOIN notify in the server if the target client
2009 is not registered (idata->registered == FALSE). The affected
2010 file is silcd/packet_receive.c.
2012 * Update the nickrec->founder in event_cumode in the Irssi SILC
2013 client. Affected file irssi/src/silc/core/silc-channels.c.
2015 * Fixed the CUMODE_CHANGE notify handling in the server when
2016 server and router are announcing their clients on channels.
2017 Now the mode changes are saved and notified correctly. The
2018 affected file is /silcd/packet_receive.c.
2020 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2021 They really did not replace the cache entry in the ID Cache.
2022 Now they do that. Affected file silcd/idlist.c.
2024 * Fixed the KICK notify handling in the Irssi SILC client to
2025 update the channel records so that the kicked client does not
2026 appear to be on the channel. The affected file is
2027 irssi/src/silc/core/silc-channels.c.
2029 * Always update the conn->current_channel when executing command
2030 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2032 * Fixed the KILL notify handling in Irssi SILC client to remove
2033 the killed client on all channels.
2035 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Fixed the silc_parse_command_line to remove extra spaces
2038 from the start and end of the arguments. Affected file is
2039 lib/silcutil/silcutil.c.
2041 * Cancel and free any active protocol in the function
2042 silc_server_close_connection. Affected file silcd/server.c.
2044 * Cancel and free any active protocol in the function
2045 silc_client_close_connction. Affected file is
2046 lib/silcclient/client.c.
2048 * Do not execute the KILL command for clients that are in
2049 history (ie. they are not in the network). Affected file is
2052 * Fixed KILL notify handling, client does not crash anymore.
2053 Affected file irssi/src/silc/core/silc-channels.c.
2055 * Reduced the default packet buffer size from 2048 to 1024 in
2056 lib/silccore/silcpacket.c.
2058 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2059 counter to the SKE context that is incresed when the SKE library
2060 performs async operation outside the library. If the outside
2061 process frees the SKE context and FREED status will be set
2062 and the library will detect after the sync operation that the
2063 libary is freed. The affected files are
2064 lib/silcske/silcske[_status].[ch].
2066 * Resolve the client entry information in the function
2067 silc_client_channel_message to assure that NULL pointer is not
2068 passed as client entry to the application. */
2070 * Fixed the task timeout calculation to assure that there is
2071 never negative timeouts. The affected file is
2072 lib/silcutil/silcschedule.c.
2074 * Fixed the channel user mode notification sending in server.
2075 It was sent point-to-point to the router (or to server by router)
2076 but it needs to be destined to a channel. The routines now
2077 supports sending the channel user mode notifys to the channels
2078 when announcing clients and channels. Affected files are
2079 silcd/server.c and silcd/packet_receive.c.
2081 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2082 It did not actually replace the old channel entry in the cache.
2083 Affected file lib/silcclient/client_notify.c.
2085 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * Fixed a possible crash in silc_packet_send_prepare. It now
2088 assures always that there is enough space in the buffer and
2089 at the tail area of the buffer (for MAC).
2091 Fixed the inbound buffer reallocation in silc_packet_read.
2092 It was old code and did not handle the reallocation correctly.
2095 The affected file is lib/silccore/silcpacket.c.
2097 * Fixed buffer overflow in silc_parse_nickname in the file
2098 lib/silcutil/silcutil.c.
2100 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * make install generates new server keys only if there is not
2105 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2108 Added check that if the NOREPLY is set then we will not send
2109 the away message. This avoids infinite loop of away messages
2110 if both clients are away. The affected file is
2111 lib/silcclient/client_prvmsg.c.
2113 * Fixed client crash if /NICK was given without arguments.
2114 Affected file lib/silcclient/command.c.
2116 * Server does not send the invite list in INVITE command back
2117 to the client if the list was not altered. Added this notion
2118 to the protocol spec as well. Affected file silcd/command.c.
2120 Fixed possible crash in INVITE command by checking the
2121 value of silc_server_get_client_route command.
2123 * Fixed the INVITE notify type handling. The arguments are now
2124 taken in correct order and client does not crash. The affected
2125 file is irssi/src/silc/core/silc-channels.c.
2127 Removed the "Inviting xxx to channel" message from the
2128 client library away and let the application handle it.
2129 Affected file lib/silcclient/command.c. Added that message
2130 to Irssi SILC client's message formats.
2132 * Fixed CMODE command crash in client. It now checks the
2133 amount of arguments correctly and does not crash. The affected
2134 file is lib/silcclient/command.c.
2136 * Do not create new channel automatically in silc_channels_join
2137 but check whether the channel by that name already exists.
2138 Affected file irssi/silc/core/silc-channels.c.
2140 * Do not send the SERVER_SIGNOFF to router if the disconnected
2141 entity was the router. Affected file silcd/server.c.
2143 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2144 SILC client as it was missing from there.
2146 Added the handling of the KICK notify to the Irssi SILC client
2147 as it was missing. Added "you have been kicked" message to
2148 Irssi SILC client's message modules formats.
2150 Added the handing of the KILL notify to the Irssi SILC client
2151 as it was missing. Added the kill message module formats
2154 The affected file is irssi/src/silc/core/silc-channels.c.
2156 * The router did not save the channel mode the server announced.
2157 Affected file silcd/packet_receive.c.
2159 * Fixed a possible crash in INFO command in server. If the
2160 server did not provide the server info it crashed. Affected
2161 file silcd/command.c.
2163 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Fixed the GETKEY command in the server to check also the
2166 global list. Otherwise the GETKEY would not work correctly
2167 in normal SILC server. Affected file silcd/command.c.
2169 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Fixed GETKEY crash, it crashed if the command did not succseed.
2173 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2176 is now real and not just an macro interface to GMP.
2178 Removed the entire GMP from the source tree and imported new
2179 NSS MPI library instead. Reason for removing GMP is that it is
2180 extremely large and compiles extremely slow. The NSS MPI
2181 is only a few files and compiles in less than 10 seconds.
2182 The speed is also about the same as GMP. The MPI is imported
2183 to lib/silcmath/mpi.
2185 If the system has GMP installed we will still use the GMP.
2186 If it is not then the NSS MPI will be compiled.
2188 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Merged a long nickname (127 characters long) crash bugfix from
2191 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2193 * Merged a freed memory reference bugfix from Irssi CVS tree.
2194 Affected file irssi/src/core/commands.c.
2196 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Added the server's public key sving and verification to the
2199 server when performing the SKE. This was missing and the
2200 remote server's (or router's) public key was accepted without
2201 checking whether we have it previously or trust it at all.
2202 Affected file silcd/protocol.c.
2204 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2206 * Check in the silc_server_timeout_remote if protocol is active
2207 and make sure that the protocol's final callback is called so
2208 that all memory if freed. Affected file silcd/server.c.
2210 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2212 * silc_server_whois_send_reply crashed the server if the nickname
2213 was 127 characters long. Affected file silcd/command.c.
2215 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Added sanity check to the silc_server_new_client. If the hostname
2218 is provided inside username then check that the provided hostname
2219 really is the same as the resolved one. If the hostname was not
2220 resolved then check it from the public key. Affected file is
2221 silcd/packet_receive.c.
2223 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2224 if the server disconnected us and the connection is not valid
2225 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2227 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2228 the library to the lib/silcutil/silcutil.[ch].
2230 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Close log file after open. Affected file
2233 lib/silcutil/silclog.c.
2235 * Check whether sock == NULL in silc_client_send_packet and return
2236 if it is. Affected file lib/silcclient/silcclient.c.
2238 * Check rec->entry == NULL in the Irssi SILC Client before
2239 sending the channel message. Affecte file is
2240 irssi/src/silc/core/silc-servers.c.
2242 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Merged a splitted window bugfix from Irssi CVS tree. The
2245 affected file is irssi/src/fe-text/textbuffer-view.c.
2247 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2248 It did not print nickname.
2250 * Improved the distributions system a bit.
2252 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2255 irssi/src/fe-text/gui-window.c.
2257 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2258 to in-active server. The affected file is
2259 irssi/src/silc/core/client_ops.c.
2261 * Resolve the client in USERS command reply if the entry does
2262 not have username resolved. The affected file is
2263 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2264 command to WHOIS command to really resolve stuff. The USERS
2265 is not used any more in any critical section so WHOIS can
2266 be used even though it might be slower than IDENTIFY.
2268 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2271 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Changed the protocol API a bit more consistent in the
2274 lib/silccore/silcprotocol.[ch].
2276 * Changed the following headers to ROBODoc format:
2278 lib/silccore/silcpayload.h
2279 lib/silccore/silcprotocol.h
2280 lib/silccore/silcsockconn.h
2282 All core library headers are now formatted.
2284 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Fixed a bug in Irssi SILC client; do not show that you are
2287 server/router operator if you really are not. Affected file is
2288 irssi/src/silc/core/client_ops.c.
2290 * Renamed silc_command_free_payload to silc_command_payload_free.
2291 Affected file lib/silccore/silccommand.h
2293 * Added silcmath.h to include the prototoypes of various routines
2294 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2297 * Changed the following headers to ROBODoc format:
2299 lib/silccore/silcchannel.h
2300 lib/silccore/silccommand.h
2301 lib/silccore/silcid.h
2302 lib/silccore/silcidcache.h
2303 lib/silccore/silcmode.h
2304 lib/silccore/silcnotify.h
2305 lib/silccore/silcpacket.h
2306 lib/silcmath/silcmath.h
2308 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Added checking to the server code not to start the server if
2311 ciphers and stuff are not configured properly. Affected files
2312 silcd/serverconfig.[h] and silcd/server.c.
2314 * Changed the layout of the header files of the public interfaces
2315 in the SILC libraries. The new layout supports ROBODoc
2316 documentation tool (and some others) so that it is easy to create
2317 a library reference manual. All the other headers and source
2318 code must still follow the CodingStyle document. Also source
2319 code must not include these ROBODoc stuffs, only the headers.
2320 Furthermore, all public interface headers must now be named
2321 by using `silc' prefix, example: silcapi.h, silccipher.h.
2322 Some files were renamed due to this. All the other headers
2323 must not be used as public interfaces. I will update the
2324 CodingStyle document later. Changed following headers, so far:
2326 lib/silcclient/silcapi.h
2327 lib/silccore/silcauth.h
2328 lib/silccore/silcprivate.h
2329 lib/silccrypt/silcdh.h
2331 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Removed silc_client_packet_send_flush from the client library
2336 as it is not needed. Affected file lib/silcclient/client.[ch].
2338 * Added printing of message of unresolved authentication method
2339 to the Irssi SILC client. Added it to the module formats.
2340 Removed the same message from the client library.
2342 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Added new distribution feature, DISTLABEL. Every distribution
2345 can define own preprocessor label that can be used in the
2346 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2347 file distributions, acconfig.h.pre and prepare.
2349 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Added Makefile.defines_int to include the actual definitions
2352 for Makefile.defines.in. Tested the new distribution system,
2353 created distributions and tested installation.
2355 * Added AWAY message printing to the Irssi SILC client. Added
2356 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2358 * Added SCONNECT command to call the SILC's CONNECT command.
2359 Cannot use CONNECT directly since Irssi uses that internally.
2360 Affected file irssi/src/silc/core/silc-servers.c.
2362 Added ACTION local command. It is same as ME command but takes
2363 the channel as mandatory argument.
2365 Rewrote some of the Irssi's help files to suite for SILC
2368 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Added Makefile.defines[.in] that should for now on be included
2371 in all Makefile.am file in the source tree. That file includes
2372 all common compilation definitions for SILC source tree.
2374 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Minor changes to the ./prepare script to change the package
2377 name according the distribution name to the configure.in.
2379 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Created new distribution system. Added file `distributions'
2382 that defines all the distributions that can be created out of
2383 the SILC source tree. The ./prepare script now reads that
2384 file to determine how to prepare the distributions. The
2385 first argument to the ./prepare is the name of the distribution
2386 and second is the version of the distribution. If given
2387 without arguments it creates the default (toolkit) distribution
2388 with the default version (defined in ./prepare).
2390 All Makefile.am files that are subject to the distributions
2391 are now named as Makefile.am.pre. These are ./Makefile.am
2392 and lib/Makefile.am. Others may be changed later.
2394 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Added invite list, ban list, some key management and connection
2397 error message printing to module formats in the Irssi SILC client.
2399 * Added new silc_client_set_away_message to set the away message
2400 that is back to the person who sent private message. The
2401 affected file lib/silcclient/silcapi.h and the
2402 lib/silcclient/client_prvmsg.c.
2404 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2406 * Fixed the private message sending in the Irssi SILC client,
2407 added local command KEY to the Irssi SILC client.
2409 Added key management and key agreement message formats to the
2410 irssi/src/fe-common/silc/module-formats.[ch].
2412 Added USERS (alias WHO) printing, server/router operator
2413 indication and LIST command printing to the module formats.
2415 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Fixed channel joining notify handling, cumode notify handling
2418 from Irssi SILC client.
2420 * Added SILC specific module-formats to the Irssi SILC client so
2421 that SILC specific message hilighting, colors etc is possible.
2422 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2424 Added channel mode, channel user mode, actions, notices,
2425 whois and whowas printing to the the module-formats.c.
2427 * Fixed a bug in channel deletion in the server. The channel
2428 is not left to the cache even if the channel founder auth mode
2429 is set when there are no users anymore on the channel. Affected
2430 file silcd/server.c.
2432 * The silc_net_localhost now resolves the entire hostname including
2433 the domain name. Affected file lib/silcutil/silcnet.c.
2435 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Changed the ask_passphrase client operation to be ascynchronous.
2438 It has now a completion callback and a context that the
2439 application must call after it has got the passphrase from
2440 the user. Affected files lib/silcclient/silcapi.h,
2441 lib/silcclient/protocol.c, lib/silcclient/command.c and
2444 Added SilcAskPassphrase callback that the application calls
2445 to deliver the passphrase to the library.
2447 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2448 The public key verification and especially a certificate
2449 verification is asynchronous procedure.
2451 Added new SILC_SKE_STATUS_PENDING status to indicate the
2452 request is pending and a callback will be called to finalize
2455 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2456 indicate that remote end did not send its public key (or
2457 certificate), even though we require it. Added check for this
2458 condition in the SKE. This was a security bug, now fixed.
2460 Defined new SilcSKEVerifyCbCompletion callback that is called
2461 when the verification process is completed.
2463 The affected files lib/silcske/silcske_status.h and
2464 lib/silcske/silcske.[ch].
2466 * Changed the verify_public_key client operation to be async
2467 as well. Defined SilcVerifyPublicKey callback that is used to
2468 indicate the success of the public key verification process.
2470 Changed the server and client to use the new async client
2473 * Changed the Irssi SILC client's internal scheduler to be called
2474 twice as many times as it used to be. As a result the client
2475 should be a bit faster now. Affected file is
2476 irssi/src/silc/core/silc-core.c.
2478 * Added support to Irssi SILC client of asynchronous public key
2479 verification and passphrase inquiry. Affected file is
2480 irssi/src/silc/core/silc-core.c.
2482 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Do not say "You have left channel %s" in client library.
2485 Moved it to the application. Affected files are
2486 lib/silcclient/command.c and silc/client_ops.c.
2488 * Fixed silc_client_get_clients. Command context was not
2489 duplicated and was freed memory in the callback. Affected
2490 file lib/silcclient/idlist.c.
2492 * Do not say "you are now talking..." on JOIN command in the
2493 client library. The appliation must handle it.
2495 * Do not say ".. changed topic to" in command reply in the
2496 client libary. The application must handle it.
2498 * Fixed TOPIC command sending in the client library.
2500 * Fixed a memory leak in silc_client_command_free in the file
2501 lib/silcclient/command.c.
2503 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2505 * Imported a modified version of Irssi client to the source tree.
2506 The Irssi will be used to create a new client called
2507 Irssi SILC. Imported to irssi/.
2509 Added silc_core_init_finish function to the Irssi. Affected
2510 file irssi/configure.in.
2512 A lot changes in the Makefile.ams around the irssi tree.
2514 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Do not rehash if the new size is same as the old size of the
2517 hash table, in the silc_hash_table_rehash*. The affected file
2518 lib/silcutil/silchashtable.c.
2520 * Replaced hash_table_del_by_context calls from the server
2521 (when channel->user_list and client->channels) to the
2522 hash_table_del as it is sufficient and faster.
2524 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Added silc_hash_table_list, silc_hash_table_get and the
2527 SilcHashTableList structure to provide an alternative way to
2528 traverse the hash table. The affected files are
2529 lib/silcutil/silchashtable.[ch].
2531 * Changed the server's idlist routines to use the hash table
2532 routines to optimize the code.
2534 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Replaced the client entry's `channel' list and channel entry's
2537 `user_list' list to hash tables for optimized lookup. Changed
2538 the code to use the hash table interface around the code.
2539 Affected file lib/silcd/idlist.[ch].
2541 * Added `auto_rehash' boolean argument to the function
2542 silc_hash_table_alloc to indicate whether the hash table should
2543 auto-rehash when it thinks is appropriate time. It will
2544 increase the hash table size if the there is twice as much
2545 entries in the table than the size of the table, and will
2546 decrease the size if there are twice as less entries than
2547 the size of the table.
2549 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2553 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2555 * silc_idcache_purge_by_context deletes the entry now by context
2556 as it is supposed to do. Affected file lib/silccore/idcache.c.
2558 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2559 client is not anymore valid (WHOWAS givens the info) and not
2560 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2562 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Removed the `data' and `data_len' arguments from the ID Cache
2565 interfaces and added `name' argument. ID Cache does not handle
2566 anymore the binary data only a names associated with given ID.
2568 * When hashing a Client ID with silc_hash_id the entire ID is
2569 not hashed anymore, instead only the hash of the Client ID is
2570 hashed. This way we can access the Client ID from the cache
2571 with Client ID but with the hash of the ID (which is a hash of
2572 the nickname) as well without any difference in performance.
2574 Added also silc_idcache_find_by_id_one_ext to do one on one
2575 searching when we have the actual ID. Added also function
2576 silc_hash_client_id_compare. The affected files are
2577 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2579 * When hashing the name associated with a ID it is always done
2580 in lowercase. This way we can access the cache without worrying
2581 about case-sensitivity, even though, for example nicknames are
2584 * Fixed a bug in server with channel message sending. It put
2585 wrong ID type as destination ID. The affected file
2586 silcd/packet_send.c.
2588 * silc_idcache_del_by_context now deletes from all hash tables
2589 by context. Affected file lib/silccore/idcache.c.
2591 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Changed the client library to use the new ID Cache interface.
2594 Changes around the source tree.
2596 * Added silc_hash_table_rehash_ext to rehash with specific
2597 hash function. Affected file lib/silcutil/silchashtable.[ch].
2599 * Added silc_hash_string_compare to compare two strings in the
2600 hash table. Affected file lib/silcutil/silcutil.[ch].
2602 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2604 * Added new function silc_idcache_del_by_context into the
2605 lib/silccore/idcache.[ch].
2607 * Changed the server's ID list routines to use the new ID Cache
2608 interface. Changes around the source tree.
2610 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Added silc_hash_table_del[_by_context]_ext functions in to the
2613 lib/silcutil/silchashtable.[ch].
2615 Removed silc_hash_table_find_all* routines and added new
2616 silc_hash_table_find_foreach to replace them.
2618 Added silc_hash_table_replace_ext function as extended
2619 replacing function. Separated the simple hash table interface
2620 from the extended hash table interface in the file
2621 lib/silcutil/silchashtable.h.
2623 * Fixed minor bugs and changed it to use some of the new
2624 hash table functions in lib/silccore/idcache.c
2626 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Added new function silc_hash_table_find_all to return all keys
2629 in the hash table by the specified key. As the hash table is
2630 collision resistant it also makes it possible to have several
2631 duplicate keys in the hash table. This function may be used to
2632 find all of the keys from the hash.
2634 Added user_context arguments to the SilcHashFunction,
2635 SilcHashCompare and SilcHashDestructor to deliver user specified
2638 Added new fuctions silc_hash_table_find[_all]_ext to do
2639 extended lookup with specified hash and compare functions and
2640 specified user contexts.
2642 Added new function silc_hash_table_add_ext to add the key
2643 with specified hash function and user context.
2645 Added new function silc_hash_table_foreach to traverse all
2646 entrys in the hash table. Added SilcHashForeach callback
2649 Added new function silc_hash_table_del_by_context to delete
2650 the entry only if the context associated with the key matches.
2652 Affected files are lib/silcutil/silchashtable.[ch].
2654 * Removed silc_hash_[server/client/channel]_id and added just
2655 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2656 silc_hash_id_compare to compare two ID's using as the hash table
2657 comparison function. Added also silc_hash_data to hash
2658 binary data and silc_hash_data_compare to compare it.
2660 * Removed silc_idlist_find_client_by_hash as it is not needed
2661 anymore. Affected file silcd/idlist.[ch].
2663 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2664 to use internally the SilcHashTable. The new ID Cache is a lot
2665 faster than the old one. Some of the ID Cache interface was also
2666 rewritten and obsolete and stupid functions were removed.
2668 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2670 * Added entry_count field to the SilcHashTable to keep the number
2671 of the entries in the table. Implemented the function
2672 silc_hash_table_rehash. Added new function
2673 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2675 Fixed a minor bug in silc_hash_table_free.
2677 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2678 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2679 into the lib/silcutil/silcutil.[ch].
2681 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * Implemented a collision resistant hash table into the
2684 lib/silcutil/silchashtable[ch]. See the header and the source
2685 for the SilcHashTable API.
2687 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Merged dotconf version 1.0.2 into lib/dotconf.
2691 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Do not compile anything in lib/silcsim/* if the SIM support
2694 is not enabled. The tree should now compile without problems
2697 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Compiled the SILC under cygwin. Compiled and tested briefly
2700 without problems. More tests needed. The SIMs didn't compile
2703 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2705 * Fixed possible crash in silc_get_username in the
2706 lib/silcutil/silcutil.c.
2708 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Fixed a va_arg in silc/client_ops.c.
2712 * Oops, RC5 routines were named AES and caused some problems
2713 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2715 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Added new SilcIDIP structure into the lib/silccore/id.h and
2718 replaced the old `ip' fields from all SILC ID's to that type.
2719 This is a step towards IPv6 support.
2721 The silc_id_get_len takes now the ID as an extra argument.
2722 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2723 both IPv4 and IPv6 based ID's.
2725 The affected files are lib/silccore/id.[ch] and other files
2726 around the tree using these routines.
2728 * Removed the ID length arguments in server from various
2729 silc_server_send_notify_* routines -> they are not needed
2732 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Fixed memory leak in silc_encode_pem_file in the file
2735 lib/silcutil/silcutil.c.
2737 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Check minor version as well in the SKE. Affected files are
2740 silcd/protocol.c and lib/silcclient/protocol.c.
2742 * Added --identifier option to the server so that an identifier
2743 can be when creating the public key for the server. Affected
2744 file is silcd/silcd.c.
2746 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2747 lib/silccrypt/silcpkcs.c.
2749 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2751 * Register default ciphers and stuff when using -C option with
2752 the server. Affected file sildc/silcd.c.
2754 * Put back the servers public key filename format, it is better
2755 than the new one. For now, the client keys are saved with the
2756 new filename format. The affected file silc/client_ops.c.
2758 * Implemented the Cipher API for the rest of the ciphers that
2759 did not implement it or implemented it the wrong way.
2761 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Register default ciphers and stuff when using the -S option
2764 in the client. Affected file silc/silc.c. Same also when
2765 creating new key pair with -C option.
2767 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Fixed the silc_verify_public_key client operation function to
2770 save the public keys differently. The fingerprint is now
2771 used as filename and not the hostname. This way also the
2772 client keys are saved uniquely and not with hostnames. The
2773 affected file is silc/client_ops.c.
2775 * Trimmed the silc_hash_fingerprint function to remove extra
2776 whitespaces from the end of the fingerprint. The affected
2777 file is lib/silccrypt/silchash.c.
2781 * Added silc_cipher_register_default function to register all
2782 default ciphers. It can be used when configuration files
2783 does not exist and the application does not want any specific
2784 ciphers in any specific order.
2786 The SilcDList is now used as silc_cipher_list dynamically
2787 allocated cipher list. Removed the static list all together
2788 and now all ciphers must be allocated to the dynamic list.
2789 The silc_cipher_alloc routine was changed to check only the
2792 All silc_cipher_* routines that used to return int returns
2795 The affected files lib/silccrypt/silccrypt.[ch].
2797 * The same thing was done to silc_hash_* as for silc_cipher_*
2798 routines. Affected files lib/silccrypt/silchash.[ch].
2800 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2801 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2802 Added also silc_pkcs_[un]register[_default] functions.
2803 Removed the data_context from the PKCS API.
2805 * Added silc_hmac_register_default function to register default
2806 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2807 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2808 to unregister all hmacs at once.
2810 * Register the default ciphers, hash functions, PKCSs and HMACs
2811 if client's configuration file does not exist. The affected
2814 * The client did not load the hash functions from the SIM
2815 modules at all. Added support for this. Affected file is
2816 silc/clientconfig.c.
2818 * When decoding public key with silc_pkcs_public_key_decode, check
2819 the supported algorithm only if PKCS are registered. Affected
2820 file lib/silccrypt/silcpkcs.c. The same was done with the
2821 silc_pkcs_private_key_decode.
2823 * Fixed the SILC List routines to keep the list always in order.
2824 It used to change the list's order when traversing the list but
2825 not it preserves the order. Affected file lib/trq/silclist.h.
2827 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Added the client library to use the SilcSocketConnection's
2830 reference counter (by silc_socket_dup) to prevent the bug that
2831 the socket object may be freed underneath async operation.
2833 * The name resolv library checking fixes in the configure.in.pre.
2836 * Created new version of the protocol drafts for future
2837 development. The -03 drafts are the ones that will be changed
2838 in the trunk now and the -02 will remain as they are.
2840 * Send list of CUMODE notifys to the router when announcing
2841 the channel users to the router. Affected file silcd/server.c.
2842 If the router receiving channel founder CUMODE for a channel
2843 that already has channel founder it will send CUMODE notify
2844 to the sender to remove the channel founder rights from the
2845 announced client. Affected file silcd/packet_receive.c.
2847 * The CUMODE notify may now use Server ID as well as the entity
2848 who changes the mode. Updated protocool specs.
2850 * Updated INSTALL and README files.
2852 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * New web pages in the http://silc.pspt.fi. The pages was
2859 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Implemented the [DenyConnectin] config section in the server.
2862 Added silc_server_config_denied_conn to check whether incoming
2863 connection is denied. Affected file silcd/serverconfig.[ch].
2865 * Do not check the ports when checking the incoming configuration
2866 data if the port is 0, meaning any. Affected file is
2867 silcd/serverconfig.c.
2869 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Fixed buffer overflow in silc_string_compare in the file
2872 lib/silcutil/silcutil.c.
2874 * Fixed double free in silc_server_command_leave in the file
2877 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Fixed the version checking in the server. Affected file is
2882 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Fixed the configuration data fetching when accepting new
2885 connections in the server. Affected file silcd/server.c.
2887 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Added `sender_entry' argument to the function
2890 silc_server_packet_relay_to_channel so that we can check
2891 whether some destination actually belongs to the same route
2892 the sender belongs (ie, we must not resend the packet to the
2893 sender). Affected file silcd/packet_send.[ch].
2895 * Added `servername' field to the SilcClientEntry in the server
2896 to hold the name of the server where client is from. Affected
2897 file is silcd/idlist.h.
2899 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Moved the channel message encrypting in the router betwen
2902 router connections from silc_server_channel_message to the
2903 silc_server_packet_relay_to_channel since we want to check
2904 whether we have anybody channel before encrypting anything.
2905 Affected files silcd/packet_[receive/send].c.
2907 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Fixed the [AdminConnection] server config section to support
2910 multiple entries. Affected file silcd/serverconfig.c.
2912 * Added support into the server to check the validity of the
2913 incoming connection before executing any KE or authentication
2916 * The connection configuration is now saved to the KE and
2917 connection auth protocol contexts and not fetched anymore in
2918 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2920 * The local hosts listenning address and port is also resolved
2921 now when starting the server. We want to have the socket object
2922 to include the real address and port for the listener. Added
2923 new function silc_net_check_local_by_sock into the files
2924 lib/silcutil/silcnet.[ch].
2926 * Fixed a broadcast bug in server -> do not broadcast if we
2929 * Fixed a routing bug. Do not route broadcast packets ever.
2930 Broadcast packets must be processed always and not routed since
2931 they may be destined to some other host than yourself and thus
2932 would get routed without no good reason. Affected file is
2935 * Added function silc_server_config_is_primary_route to check
2936 whether primary router connection has been configured (a router
2937 configuration that we are initiating). If there is not, we
2938 will assume that there is only two routers in the SILC network
2939 and we will use the incoming router connection as our primary
2940 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2942 * Changed the order of the broadcasting. Broadcast _after_ the
2943 packet has been processed not before. Affected file is
2946 * Fixed a [ClientConnection] parsing bug. The port was never
2947 parsed correctly thus resulting to port 0. Affected file
2948 silcd/serverconfig.c.
2950 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2951 argument and did not set the broadcast packet flag. Affected
2952 file silcd/packet_send.c. Fixed same bug in the function
2953 silc_server_send_notify as well.
2955 * If we receive NEW_ID packet for our own ID in the server, ignore
2958 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Removed the nickname from the Private Message Payload.
2963 Updated the code and the protocol specs.
2965 * Updated protocol specs for submitting to the IETF.
2967 * Tweaked the Random Number Generator a bit. Affected file
2968 lib/silccrypt/silcrng.c. Exported a new function
2969 silc_rng_[global]_add_noise which can be used to add more
2972 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Do not parse packets with different timeout when protocol
2975 is active -> may cause problem with rekey. Affected file
2978 * When server receives signoff notify it must not create
2979 new channel key if the client is on any channels since the
2980 sender of the signoff notify will create it.
2982 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Added printing of error messages during SKE protocol from the
2985 failure packet sent by server during SKE. Affected file
2988 * Removed the client's failure_callback handling with timeout
2989 and handle it immediately when received.
2991 * The SKE library returned wrong type in SUCCESS and FAILURE
2992 packets. They must be 32 bit MSB not 16 bit MSB.
2994 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Ok, rewrote the logic of the re-key and now it seems to work.
2997 I tested it on high traffic with frequent re-keys without
2998 problems. Added hmac_receive (and renamed hmac to hmac_send)
2999 in SilcClientConnection in lib/silcclient/client.h and
3000 in SilcIDListData in silcd/idlist.h. Also, removed the
3001 SilcPacketParserContext's cipher and hmac fields as they are
3002 not needed anymore and actually caused some problems when
3003 the ciphers and hmac's changed underneath the packet parser.
3005 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * If re-key protocol is active then process the incoming packets
3008 synchronously since we must assure that icoming packets encrypted
3009 with the old key is processed before the new keys is set to
3010 use. This is true other packets than for REKEY packets.
3011 Affected file silcd/server.c. The same was done to client library
3012 as well, affected file lib/silcclient/client.c.
3014 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3016 * Fixed bug in client and server to accept the force send if
3017 the packet is send from silc_[server/client]_packet_process
3018 function. Otherwise the packets are never delivered, oops.
3020 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Disable force sending of packets when REKEY protocol is active.
3023 We must assure that no packet is sent directly when rekey is
3024 performed. All packets must be sent through packet queue.
3025 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3026 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3027 function is silc_[server/client]_packet_send_real to check
3030 * Replaced the SIM paths from example config files to
3031 /usr/local/modules. Also, make install creates now
3032 /usr/local/silc/logs directory to hold all the SILC server
3035 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Made the configure.in.pre work on Solaris. Patch by salo.
3039 * Made all ciphers compatible with non-x86 machines. Defined
3040 CBC mode macros into lib/silccrypt/ciphers_def.h.
3042 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Fixed the make install.
3046 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * When MAC computation fails the silc_packet_decrypt returned 0
3049 even though it was supposed to return -1. Fixed this. The
3050 affected file is lib/silccore/silcpacket.c.
3052 * Do not replace the config files in /etc/silc (in make install)
3053 if they already exist. Affected file ./Makefile.am.
3055 * Do not send re-key packets immediately but through packet queue.
3056 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3058 * Changed silc_net_check_host_by_sock to return FALSE if the
3059 IP/DNS could not be resolved. Though, it returns the IP address
3060 now even if it could not resolve it (but returns also FALSE).
3061 Affected file lib/silcutil/silcnet.[ch].
3063 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added silc_pkcs_decode_identifier to decode the public key's
3066 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3067 Added also silc_pkcs_free_identifier. Added also new context
3068 SilcPublicKeyIdentifier.
3070 * Added -S option to the silc client. It is used to dump the
3071 contents of the specified public key file.
3073 * Changed the PKCS api to return the public key length when
3074 setting the public key.
3076 * Fixed a fatal bug in the public and private key file loading.
3077 Affected file lib/silccrypt/silcpkcs.c.
3079 * Execute the packet parsing for client with zero (0) timeout
3080 if the protocol is active. Affected file silcd/server.c.
3082 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Made the key generation options to the silcd program. Added
3085 -C option, equivalent to client's option.
3087 * Added new [ServerKeys] config section to the server. It
3088 configures the server's public and private key.
3090 * Defined generic Public Key Payload into the protocol
3091 specification to send specific type of public keys and
3094 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3095 public key or certificate.
3097 * Implemented the GETKEY command to the server and to the
3098 client library and on user interface.
3100 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Made preliminary `make install' work.

3131 SilcClientConnection structure; not needed. Affected file is
3132 lib/silcclient/client.h.
3136 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Do not ask whether user wants to use the negotiated private key
3139 for private messages, just use it. Affected file is
3140 silc/local_command.c.
3142 * Added `send_enc_key' and `enc_key_len' fields to the
3143 SilcIDListData structure since they are needed in the re-key
3144 phase. Affected file is silcd/idlist.[ch].
3146 * Implemented the simple re-key protocol into the server.

3158 the PFS is to be performed in the re-key. Affected file is
3161 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3164 int64 of at least the xintXX size. If void * is less that 4
3165 bytes uint32 * will be used. Defined bool as boolean.
3167 * Changed _ALL_ unsigned long and unsigned int to uint32,
3168 unsgined short to uint16 in the source tree.
3170 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3171 not handle clients that has entry->data.registered == FALSE.
3172 They are not in the network anymore. Affected file is
3175 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Implemented the sending of the SERVER_SIGNOFF notify in the
3178 server. Affected file is silcd/server.c.
3180 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3181 Added also silc_notify_payload_encode_args into the

3184 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3185 Affected file silcd/packet_receive.c.
3187 * Implemented the SERVER_SIGNOFF notify handling in the client
3188 library. Affected file lib/silcclient/client_notify.c. Also,
3189 implemnted the printing of the SERVER_SIGNOFF info to the
3190 application. Affected file silc/client_ops.c.
3192 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3193 if the deleting was successful. Affected file silcd/idlist.[ch].
3195 * Added support for public key authentication in the connection
3196 authentication protocol in the client library. Affected file
3197 lib/silcclient/protocol.c.
3199 * Changed the server's silc_idlist_get_clients_by_* interface
3200 to support already allocated array so that new entries may be
3201 added to pre-allocated array. Affected file silcd/idlist.[ch].
3202 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3203 and command replies.
3205 * All command reply functions in the server now calls the
3206 pending command callback even if error occured. This way the
3207 error will be delivered to the client as well. Affected files
3208 silcd/command.c and silcd/command_reply.c.
3210 * Fixed INFO command to return local server's info if no server
3211 was provided. Affected file lib/silcclient/command.c.
3213 * Removed RESTART command for good. Updated the code and the
3216 * Rewrote parts of the task system. It is a bit simpler now.
3217 Removed unsued task priorities. The affected files are
3218 lib/silcutil/silctask.[ch].
3220 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Moved the USERS printing from the library to the application.
3223 Affected files lib/silcclient/command.c and silc/client_ops.c.
3225 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Added channel key re-key support. The re-key is perfomed
3230 only by the router and is done once in an hour. Added `rekey'
3231 field to the SilcChannelEntry in the server. Affected files
3232 silcd/server.c and silcd/idlist.h.
3234 * Added silc_task_unregister_by_context into the file
3235 lib/silcutil/silctask.[ch].
3237 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Added SILC_UMODE_GONE mode to indicate when the client is not
3240 present in the SILC network. Added also support to the local
3241 command AWAY that will set this mode. Added support of showing
3242 "xxx is gone" in WHOIS command. The USERS command shows the
3243 gone status as well.
3245 * Fixed setting server and router operator privileges in the
3246 server's UMODE command. Affected file silcd/command.c.
3248 * Merged the SKE KE1 and KE2 payloads into one payload. The
3249 new KE payload is equivalent to the old KE2 payload.
3251 Cleaned up the SKE Start Payload parsing. It now uses the
3252 simple buffer unformatting to do the parsing. A lot faster
3255 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3256 to the SKE that is used to indicate whether both of the SKE
3257 parties should perform authentication. By default only the
3258 responder performs authentication. By setting this flag also
3259 the initiator must do authentication. By default it is unset
3260 since in normal SKE case, client to server connection, only
3261 the responder should do authentication. When doing SKE between
3262 two clients both should perform authentication. Updated the
3263 code and the protocol specs.
3265 * A little fix to IDENTIFY command in the server. Search the
3266 client first by hash not nickname. Affected file is
3269 * Fixed the silc_client_close_connection to support closing
3270 the client to client connections wihtout deleting too much
3271 data. Affected file lib/silcclient/client.c.
3273 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3274 are received if protocol used to be active but is not anymore
3275 the application would crash due to NULL pointer dereference.
3276 Affected files silcd/server.c and lib/silcclient/client.c.
3278 * Added `hash' field to the SilcClientConnection to include
3279 the hash function negotiated in the SKE protocol.
3281 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3282 to set the channel founder authentication data. A client can
3283 claim the founder rights later by providing the authentication
3284 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3285 This way the channel founder can regain the channel founder
3286 privileges even it is left the channel. This works only on
3287 local server and the client must be connected to the same
3288 server to be able to regain the founder rights. Updated the
3289 protocol specs accordingly.
3291 Added support to the CMODE command in the client to set the
3292 founder auth data. Read the README to see how to set it.
3294 Added support to the CUMODE command to claim the founder
3295 rights. Read the README to see how to do it.
3297 Added support for the founder authentication to the Channel
3298 Entry in the server. Affected file silcd/idlist.h.
3300 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3301 server's CMODE command. Affected file silcd/command.c.
3303 * Added the following new functions into lib/silccore/silcauth.[ch]:
3304 silc_auth_get_method and silc_auth_get_data.
3306 * The server now saves the remote hosts public key to the
3307 SilcIDListData pointer. Affected file silcd/protocol.c.
3309 * The normal server now does not remove the channel entry from
3310 the cache if the founder authentication data is set. It used
3311 to remove it if the founder was the last one on the channel on
3312 the server and left the channel. The auth data is saved and
3313 if the channel is re-joined later the old entry is used with
3314 the old auth data. Affected files silcd/command_reply.c and
3317 * Removed the `pkcs' field from the SilcIDListData structure
3318 in the server; it is not used. Affected file silcd/idlist.h.
3320 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Fixed packet processing on slow links. Partial packets were
3323 never re-processed because the incoming data buffer was cleared
3324 by the application. Application must not directly clear the
3325 sock->inbuf, the packet processing routines handle it. Fixed
3326 this in client library and in server.
3328 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Fixed the WHOIS and IDENTIFY send reply function to really
3331 check whether to send list or just one entry. Affected file
3334 * Cleaned up the LEAVE command's channel key distribution. The
3335 affected file silcd/command.c.
3337 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3338 can enforce the channel mode as well. In that case the ID
3339 includes the ID of the server. The code now enforces the
3340 mode change if the router have different mode than the server.
3342 * The notify client operation with CMODE_CHANGE notify can now
3343 return NULL client_entry pointer if the CMODE was not changed
3344 by client. Application must check for this.
3346 * Added <Server ID> argument to INFO command to support server
3347 info fetching by Server ID.
3349 * Added silc_server_announce_get_channel_users to get assembled
3350 packets of channel users of the specified channel. Affected
3351 file silcd/server.[ch].
3353 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3354 was freed underneath the ID Cache.
3356 * Re-announce clients when the server received CHANNEL_CHANGE
3357 notify from the router. Affected file silcd/packet_send.c.
3359 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3362 crashed since it did not handle the fact that there is no cipher
3363 called "3" and didn't check the error condition. Now fixed.
3365 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3366 flag. It can be used to send message requests.
3368 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Implemented the RESTART command in the client.
3372 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3373 notice type messages. Added notice printing to the user
3376 * The channel keys are not re-generated if the channel's mode
3377 is PRIVKEY, ie private key on the channel exists. Affected
3378 files silcd/server.c and silcd/command.c.
3380 * Fixed a little bug in channel message delivery when channel
3381 private keys are set in the server. Affected file is
3382 silcd/packet_send.c.
3384 * Changed the setting on channel->on_channel = TRUE from the
3385 silc_client_save_channel_key to the JOIN command reply. The
3386 key payload is not received if the private channel key is set.
3387 Affected file lib/silcclient/command_reply.c and the
3388 lib/silcclient/client_channel.c.
3390 * When the CMODE_CHANGE notify is sent and the channel private
3391 key mode is removed the channel key must be re-generated in
3392 other cells as well. Added this support for the router in the
3393 silcd/packet_receive.c.
3395 * Added new local command NOTICE to send notice message on
3396 channel. Affected file silc/local_command.[ch].
3398 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Added new local command ME to the client. It is used to send
3401 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3402 some action. Affected file silc/local_command.[ch].
3404 * Changed channel_message and private_message client operations
3405 to deliver the message flags to the application. Added also
3406 the `flags' arguments to the silc_client_send_channel_message
3407 and silc_client_send_private_message functions. Affected file
3410 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Redefined the Private Message Payload to support private message
3413 keys and to support the new private message flags. Updated
3414 the protocol specs. Flags makes it possible to have for example
3415 CTCP style messages.
3417 * Added new type SilcPrivateMessagePayload and defined an API
3418 for it in the lib/silcclient/silcprivate.[ch].
3420 * Tested private message private keys successfully. Tested the
3421 private message key set, unset and list commands with the new
3424 * Redefined the Channel Message Payload to include the channel
3425 message flags (equal with private message flags) to support
3426 for example CTCP style messages.
3428 * Defined some of the message (for channel and private message)
3429 flags. Updated the protocol specs and added the flags to the
3430 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3432 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Added SilcKeyAgreementStatus type to the key agreement routines
3435 to indicate the current status and error if one occured.
3436 The status types are defined in the lib/silcclient/silcapi.h.
3438 * Added new local command KEY that is used to set and unset private
3439 keys for channels, set and unset private keys for private messages
3440 with remote clients and to send key agreement requests and
3441 negotiate the key agreement protocol with remote client. The
3442 key agreement is supported only to negotiate private message keys,
3443 it currently cannot be used to negotiate private keys for channels,
3444 as it is not convenient for that purpose.
3446 * Fixed a minor pending callback setting bug in the function
3447 silc_client_get_client_by_id_resolve, now the function works.
3448 Affected file lib/silcclient/idlist.c.
3450 * Added function silc_net_get_local_port to get local bound
3451 port by socket. Added to lib/silcutil/silcnet.[ch].
3453 * Added `sockets' and `sockets_count' fields to the SilcClient
3454 object. They hold the sockets of the listenning sockets in
3455 the client. Listenning sockets may be for example the key
3456 agreement server. Affected file lib/silcclient/client.[ch].
3457 Added functions the silc_client_add_socket and the
3458 silc_client_del_socket. They are exported to the application
3461 * Added ~./silc/clientkeys to support other client's public keys.
3463 * Renamed verify_server_key client operation to verify_public_key
3464 and added one argument to indicate the type of the connection
3465 (server, client etc.).
3467 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * Added silc_server_connection_auth_request to handle the
3470 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3471 silcd/packet_receive.[ch].
3473 * Added silc_server_send_connection_auth_request into the
3474 silcd/packet_send.c to send the connection auth request packet.
3476 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3479 * Fixed the public key authentication in responder side in the
3480 server. The `auth_data' pointer includes the SilcPublicKey
3481 not the path to the public key. Affected file silcd/protocol.c.
3483 * Implemented the public key authentication in the initiator side
3484 in the server. Affected file silcd/protocol.c.
3486 * Removed the [RedirectClient] config section from the server
3487 configuration. Is not needed and I don't want to implement it.
3489 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Cleaned up the CMODE command in the server. It now works
3492 correctly and supports all the modes defined in the protocol.
3493 Affected file is silcd/command.c.
3495 * Added `hmac_name' field to the SilcChannelEntry in the server
3496 to hold the default HMAC of the channel. It can be set when
3497 creating the channel (with JOIN command). Affected files
3500 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3501 type to indicate the change of the current cipher and hmac
3502 on the channel. Client can safely ignore the <cipher> argument
3503 (if it chooses to do so) since the CHANNEL_KEY packet will
3504 force the channel key change anyway. The <hmac> argument is
3505 important since the client is responsible of setting the new
3506 HMAC and the hmac key into use.
3508 * Fixed the CMODE command in the client library as well.
3510 * Tested CMODE command in router environment successfully.
3512 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Show the version of the remote client (or server) when connecting
3515 to the server. It is logged to the log file. Affected file
3516 is silcd/protocol.c.
3518 * Fixed the KILLED notify handling in the client library. The
3519 client must be removed from all channels when receiving the
3522 Also, do not remove the client entry when giving the KILL
3523 command but when the KILLED notify is received.
3525 * Removed silc_idlist_find_client_by_nickname from the server.
3526 Not needed anymore. Affected files silcd/idlist.[ch].
3528 * Implemented the CHANNEL_CHANGE notify type handling to the
3529 server. Affected file silcd/server.c.
3533 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Added silc_server_send_notify_invite to send the INVITE
3536 notify between routers.
3538 * Implemented the INVITE command correctly to the server.

3547 * Added function silc_server_get_client_resolve to find the
3548 client entry by ID from all ID lists and then resolve it
3549 (using WHOIS) if it cannot be found. Affected file is
3552 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Implemented the BAN command to the client library.
3556 * The JOIN command in the server now checks the invite list
3559 * Changed the silc_command_reply_payload_encode_va and the
3560 silc_command_payload_encode_va to support that if argument is
3561 NULL it ignores and checks the next argument. Affected file
3562 lib/silccore/silccommand.c.
3564 * Added silc_server_send_notify_ban to send the BAN notify
3565 type between routers.
3567 * Chaned the silc_notify_payload_encode to support that if
3568 argument is NULL it ignores and checks the next argument.
3569 Affected file lib/silccore/silcnotify.c.
3571 * Tested ban lists in router environment successfully.
3573 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Implemented BAN command to the server, in silcd/command.[ch].
3577 * Removed the BAN and INVITE_LIST modes from the CMODE command
3580 * Added function silc_string_match to regex match two strings.
3581 Affected files lib/silcutil/silcutil.[ch].
3583 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Redefined parts of the SilcChannelEntry in the server to support
3586 the new ban and invite lists.
3588 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Redefined the INVITE command. The same command can be used to
3591 invite individuals to the channel but also to manage the invite
3592 list of the channel (to add to and remove from the invite list).
3593 Updated the protocol specs.
3595 * Added new command SILC_COMMAND_BAN that can be used to manage
3596 the ban list of the channel. Updated the protocol specs.
3598 * Removed the channel modes: the SILC_CMODE_BAN and the
3599 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3600 in the CMODE command. The equivalent features are now available
3601 using INVITE and BAN commands. Updated the protocol specs.
3603 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3604 in the network about change in the current ban list. The notify
3605 type is not used by the client.
3607 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3608 support the invite lists.
3610 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Added new function silc_string_regexify that converts string
3613 including wildcard characters into regex string that can
3614 be used by the GNU regex library. Added into the file
3615 lib/silcutil/silcutil.[ch].
3617 Added silc_string_regex_combine to combine to regex strings
3618 into one so that they can be used as one regex string by
3619 the GNU regex library. Added into the file
3620 lib/silcutil/silcutil.[ch].
3622 Added silc_string_regex_match to match two strings. It returns
3623 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3625 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3627 * Imported GNU regex to the soruce tree into lib/contrib.
3628 Fixed some compiler warning from the regex.c.
3630 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Fixed MOTD command in the server to work in router environment.
3634 * Fixed the MOTD command in the client library to support
3635 the server argument in the command.
3637 * Added `nickname_len' argument to the silc_idlist_add_client
3638 in the server, as the `nickname' argument may be binary data
3641 * Added silc_idlist_get_channels to return all channels from
3644 * Implemented LIST command to the server. Affected file is
3647 * Implemented the LIST command to the client library and on the
3650 * Added [<user count>] argument to the LIST command reply.
3651 With private channels the user count is not shown.
3653 * Updated TODO and README.
3655 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * The client entry's data.registered must be TRUE even with
3658 global client entry on global client list. The data.registered
3659 is used to check whether the client is anymore in the network,
3660 for example with WHOWAS command so it must be valid.
3662 * Fixed the WHOWAS command in the server. It now actually works
3663 in router environment. Added function into silcd/command_reply.c
3664 silc_server_command_reply_whowas_save.
3666 * Added silc_idlist_purge function to the silcd/idlist.c
3667 to periodically purge the ID Cache.
3669 * Fixed INFO command in the server. It works now in router
3670 environment. Added <server name> argument to the INFO command
3671 reply. Updated the protocol specs.
3673 * Fixed minor bug in silc_idcache_purge to not purge if the
3674 expire value is zero.

3677 they were buggy because of the WHOWAS information.
3679 * Fixed local command MSG to handle the async resolving of
3680 the remote client properly. It used to fail the first MSG.
3681 Affected file silc/local_command.c.
3683 * Added `data_len' field to SilcIDCache context.
3685 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Update TODO. Todo in commands in the server.
3689 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3692 used by routers as broadcast packet to inform other routers
3693 about the changed user mode.
3695 Implemented the notify handling in the server. Affected file is
3696 silcd/packet_receive.c. Added the function
3697 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3699 * Added new generic Channel Payload and deprecated the New Channel
3700 Payload. The New Channel Payload is now the generic Channel
3703 * Added new argument `mode' to the silc_server_send_new_channel
3704 as it is required in the Channel Payload now.
3706 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3707 and created a new and real SilChannelPayload to represent the
3708 new generic Channel Payload. Implemented the encode/decode
3709 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3711 * Added silc_server_get_client_channel_list to return the list
3712 of channels the client has joined for WHOIS command reply.
3713 Affected file silcd/server.[ch].
3715 * Implemented the channel list sending in the WHOIS command reply
3716 in server and in the client.
3718 Implemented the channel list displaying on the user interface
3719 as well. Affected file silc/client_ops.c.
3721 * Added silc_channel_payload_parse_list to parse list of Channel
3722 Payloads. It returns SilcDList list of SilcChannelPayloads.
3723 Client for example can use this function to parse the list of
3724 channels it receives in the WHOIS command reply. The caller
3725 must free the list by calling silc_channel_payload_list_free.
3726 Affected files lib/silccore/silcchannel.[ch].
3728 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Added one new argument <user mode> to the WHOIS command reply
3731 to return the mode of the user in SILC. Updated the protocol
3734 Implemented it to the server and client.
3736 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3741 * Implemented the UMODE command and user modes in general to the
3742 client library and to the user interface.
3744 * Implemented the UMODE command to the server.
3746 * The server now sends UNKNOWN_COMMAND error status if client sends
3747 unknown command. Affected file silcd/command.c.
3749 * All server commands now handle the command identifier the right
3750 way when sending the command reply to the client. The client can
3751 use to identify the command replies with the identifier.
3753 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Added silc_server_get_client_route to resolve the route to
3756 the client indicated by the client ID. Affected file is
3759 * Added silc_server_relay_packet as general function to relay
3760 packet to arbitrary destination. This deprecates functions
3761 like _send_private_message_key, _relay_notify etc. Affected
3762 file is silcd/packet_send.[ch].
3764 Removed silc_server_send_key_agreement,
3765 silc_server_send_private_message_key and
3766 silc_server_packet_relay_notify functions from the file
3767 silcd/packet_send.[ch].
3771 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3772 server. Affected file silcd/packet_receive.[ch].
3774 * Implemented the KILL command to the client. Implemented the
3775 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3776 Affected files lib/silcclient/command[_reply].c and
3777 lib/silcclient/client_notify.c. Implemented the KILL notify
3778 printing in the user inteface.
3780 * Fixed a lot silc_parse_nick memory leaks from the client
3781 library in the file lib/silcclient/command.c.
3783 * Changed the silc_server_send_notify_on_channels's `sender'
3784 argument from SilcSocketConnection to SilcClientEntry to
3785 check the sender as entry and not as connection object and not
3786 to send to the client provided as argument. The affected file
3787 is silcd/packet_send.[ch].
3789 * The notify packets that are destined directly to the client used
3790 to not to be processed by the server. Now changed that and the
3791 server processes all notify packets. After relaying the packet
3792 to the client the notify packet is processed in the server.
3794 * The silc_server_free_client_data now checks whether there is
3795 pending outgoing traffic for the client and purges the data to
3796 the network before removing the client entry.
3798 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3801 an client is killed from the SILC Network. Updated the protocol
3804 Added new function silc_server_send_notify_killed to the
3805 silcd/packet_send.[ch].
3807 * Added function silc_server_packet_relay_notify to relay notify
3808 packets that are destined directly to a client. In this case
3809 the server does not process the notify packets but merely relays
3810 it to the client. Affected file silcd/packet_send.[ch].
3812 Added also silc_server_packet_process_relay_notify to check
3813 whereto relay the notify. Affected file is
3814 silcd/packet_receive.[ch].
3816 * Implemented the KILL command to the server.
3820 * Added the backup schema desgined last fall to the protocol
3821 specs for everyone to see. The specification is in the
3822 *-spec-xx.txt draft and the packet type definitions for the
3823 backup routers is in *-pp-xx.txt draft. Thusly, added also
3824 new packet type SILC_PACKET_CELL_ROUTERS.
3826 * A big security problem in the implementation discovered. The
3827 signoff of an client did not cause new channel key generation
3828 which it of course should've done. The channel keys must be
3829 always re-generated when client leaves (or signoffs) the channel.
3830 The silc_server_remove_from_channels funtion now handles
3831 the channel key re-generation.
3833 * Added `sender' argument to the silc_server_send_notify_on_channels
3834 to not to send the client provided as argument. Affected file
3835 silcd/packet_send.[ch].
3837 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Implemented OPER and SILCOPER commands into the server and
3842 * Added silc_auth_verify and silc_auth_verify_data to verify
3843 the authentication directly from the authentication payload.
3844 It supports verifying both passphrase and public key based
3845 authentication. Affected file lib/silccore/silcauth.[ch].
3847 * Added `hash' field to the SilcIDListData structure. It is the
3848 hash negotiated in the SKE protocol. Affected file is
3851 * Slight redesigning of the SilcAuthPayload handling routines.
3852 Do not send SilcPKCS but SilcPublicKey as argument.
3854 * Implemented the public key authentication support to the
3855 serverconfig. The public key is loaded from the provided path
3856 and saved as authentication data to void * pointer. Thus,
3857 changed the unsigned char *auth_data to void *auth_data;
3859 * Fixed SHUTDOWN command to send the reply before the server
3860 is shutdown. :) Affected file silcd/command.c.
3862 * Fixed fatal bug in CONNECT command. The hostname was invalid
3863 memory and server crashed. Affected file silcd/command.c.
3865 * Fixed fatal bug in CLOSE command. The server_entry became
3866 invalid but was referenced later in the command. Affected file
3869 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Fixed fatal bug in failure packet handling. Server ignored
3872 the failure and thus crashed when it came.
3876 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3879 that the command may be executed only once in (about) 2 seconds.
3880 The old SILC_CF_LAG flag is same but allows command bursts up
3881 to five before limiting.
3883 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3884 server code. Various commands now includes the CF_LAG_STRICT
3885 flag to disallow any kind of miss-use of the command.
3887 * Fixed the silc_buffer_unformat to not to allocate any data
3888 if the length of the data is zero. It used to allocate the
3889 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3891 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Changed the format of AdminConnection configuration section
3894 in the server. Added username of the admin to the format.
3895 Affected files silcd/serverconfig.[ch].
3897 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3898 to return admin configuration data by host, username and/or
3901 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Implemented WHOWAS command to the server. Added the functions:
3905 silc_server_command_whowas_parse,
3906 silc_server_command_whowas_send_reply,
3907 silc_server_command_whowas_from_client and
3908 silc_server_command_whowas_from_server
3910 * Added <Client ID> argument to the WHOWAS command reply. Updated
3911 the protocol specs accordingly.
3913 * Implemented WHOWAS command and command_reply to the client
3916 Implemented the WHOWAS printing on the user interface.
3918 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Added new argument to the WHOWAS command reply, the real name.
3921 It is an optional argument. Updated the protocol specs.
3923 * Added SilcIDCacheDestructor callback that is registered when
3924 the SilcIDCache is allocated. The callback is called when
3925 an cache entry in the ID Cache expires, or is purged from the
3926 cache. Added into lib/silccore/idcache.[ch].
3928 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3929 to destruct the client entries when the cache entry expires.
3930 Other ID Cache's in server and in the client library ignores
3933 * If the ID Cache entry's `expire' field is zero then the entry
3934 never expires. Added boolean `expire' argument to the
3935 silc_idcache_add function in the lib/silccore/idcache.[ch].
3936 If it is TRUE the default expiry value is used.
3938 * Added silc_server_free_client_data_timeout that is registered
3939 when client disconnects. By default for 5 minutes we preserve
3940 the client entry for history - for WHOWAS command.
3942 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Added support to the server to enforce that commands are not
3945 executed more than once in 2 seconds. If server receives
3946 commands from client more frequently, timeout is registered
3947 to process the commands. Affected file silcd/command.c.
3948 Added new function silc_server_command_process_timeout.
3950 * Changed NICK_NOTIFY handling in client library to check that
3951 if the client's nickname was changed, so there is no need to
3952 resolve anything from the server.
3954 * Removed error printing from the WHOIS and IDENTIFY commands.
3955 If error occurs then it is ignored silently in the client library.
3956 The application, however, may map the received error to
3957 human readable error string. The application currently maps
3958 the NO_SUCH_NICKNAME error to string.
3960 * Made the command status message public to the application. Moved
3961 them from lib/silcclient/command_reply.c to
3962 lib/silcclient/command_reply.h. The application can map the
3963 received command status to the string with the
3964 silc_client_command_status_message function.
3966 * Added check to the server to check that client's ID is same
3967 as the Source ID in the packet the client sent. They must
3970 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Added dist-bzip hook to the Makefile.am to make bzip2
3973 compressed distributions.
3975 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Server now enforces the maximum length for the nickname and
3978 the channel as protocol specification dictates. 128 bytes for
3979 nickname and 256 bytes for channel name.
3981 * Moved the WHOIS printing to the application. The client libary
3982 does not print out the WHOIS information anymore, the application
3983 must do it. Renamed silc_client_command_reply_whois_print to
3984 the silc_client_command_reply_whois_save.
3986 The client's idle time is also sent to the application now, and
3987 the idle is shown on screen.
3989 * Added silc_client_command_reply_identify_save to save the
3990 received IDENTIFY entries.
3992 * Do not check for channel private keys in message sending and
3993 reception if the channel does not have the PRIVKEY mode set.
3994 Affected file lib/silclient/client_channel.c.
3996 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3999 just surfaced after chaning the JOIN procedure.
4001 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Added silc_client_get_clients_by_list to get client entries
4004 from Client ID list, that is returned for example by JOIN
4005 and USERS command replies. The application should use this
4006 function for example when JOIN command reply is received to
4007 resolve the clients already on the channel (library does not
4008 do that anymore as USERS command reply is not used in the JOIN
4009 procedure anymore). Affected files lib/silcclient/silcapi.h and
4010 lib/silcclient/idlist.c.
4012 * JOIN command reply and USERS command reply returns now SilcBuffer
4013 pointers instead of unsigned char pointers when returning
4014 the client list and mode list.
4016 * Added <Client ID> argument to the JOIN command reply, mainly
4017 for the server to identify for which client the command was
4018 originally sent. Updated protocol specs accordingly.
4020 * Added SilcDlist private_key pointer to the SilcChannelEntry
4021 in the client to support the channel private keys. Affected
4022 file is lib/silcclient/idlist.h.
4024 * Added SilcChannelPrivateKey argument to the function
4025 silc_client_send_channel_message so that application can choose
4026 to use specific private ke if it wants to. If it is not provided,
4027 the normal channel key is used, unless private keys are set.
4028 In this case the first (key that was added first) is used
4029 as the encryption key.
4031 * Implemented the support for channel private key handling.
4032 Implemented the following functions:
4034 silc_client_add_channel_private_key,
4035 silc_client_del_channel_private_keys,
4036 silc_client_del_channel_private_key,
4037 silc_client_list_channel_private_keys and
4038 silc_client_free_channel_private_keys
4040 Affected file lib/silcclient/client_channel.c.
4042 * Added the support for the private keys in the channel message
4043 sending and encryption and in the message reception and
4044 decryption. Affected funtions are
4045 silc_client_send_channel_message and silc_client_channel_message.
4047 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Added SKE's key verify callback to the client library's
4050 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4052 * Removed the statement that server (or router) must send USERS
4053 command reply when joining to the channel so that the client
4054 knows who are on the channel. Instead, the client list and
4055 client's mode list is now sent in the JOIN command reply to the
4056 client who joined channel. This is better solution.
4058 * Added function silc_server_get_users_on_channel and function
4059 silc_server_save_users_on_channel to the silcd/server.[ch].
4061 * Removed function silc_server_command_send_users from the
4064 * Do not show topic on the client library anymore. The topic is
4065 sent in the command reply notify to the application and the
4066 application must show the topic now.
4068 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Added client searching by nickname hash into the IDENTIFY and
4071 WHOIS commands in the server as they were clearly missing from
4072 them. Affected file is silcd/command.c.
4074 * Fixed a bug in private message receiving in the client library.
4075 The remote ID was freed and it wasn't supposed, now it is
4078 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Minor fix to the channel payload; allocate the data area, as it
4081 needs to be of specific length.
4083 * If the key agreement port is zero then the operating
4084 system will define the bound port. Affected files are
4085 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4087 * Added new function silc_channel_payload_decrypt into the file
4088 lib/silccore/silcchannel.[ch].
4090 * Moved the channel message etc, check from silc_packet_decrypt
4091 to applications. The library calls now a generic
4092 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4093 when the packet is either normal or special. This was done to
4094 allow more wide range of checking that was not allowed when
4095 the code was in library. Now applications can do virtually any
4096 checks to the packet and return to the library the decision how
4097 the packet should be processed. Affected files are
4098 lib/silccore/silcpacket.[ch].
4100 Added silc_server_packet_decrypt_check to the server and
4101 silc_client_packet_decrypt_check to the client library.
4103 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4104 to send with specified source and destination information.
4106 * Channel message delivery between routers was broken after the
4107 channel key distribution was fixed earlier. The channel key
4108 was used be to distributed to other routers as well which is not
4109 allowed by the protocol. Now this is fixed and channel keys
4110 really are cell specific and the channel message delivery between
4111 routers comply with the protocol specification.
4113 * Fixed various commands in server to check also the global list
4114 for the channel entry and not just the local list. The affected
4115 file silcd/command.c.
4117 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Added assert()s to buffer formatting and unformatting routines
4120 to assert (if --enable-debug) when error occurs. Affected
4121 file: lib/silcutil/silcbuffmt.c.
4123 * Changed to auto-reconnect to check whether the remote host is
4124 router and register the re-connect timeout if it is. It used
4125 to check that whether we are normal server, but router must do
4126 auto-reconnect with another router as well. Affected file
4129 * Removed the [<key len>] option from CMODE command as the cipher
4130 name decides the key length, nowadays. See the defined ciphers
4131 from the protocol specification.
4133 * Added [<hmac>] option to the CMODE command to define the HMAC
4134 for the channel. Added SILC_CMODE_HMAC channel mode.
4136 * Added [<hmac>] option for the JOIN command so that user can
4137 select which HMAC is used to compute the MACs of the channel
4140 * Added Hmac field to the Channel Message Payload. The integrity
4141 of plaintext channel messages are now protected by computing
4142 MAC of the message and attaching the MAC to the payload. The
4143 MAC is encrypted. Now, it is clear that this causes some
4144 overhead to the size of the packet but rationale for this is that
4145 now the receiver can verify whether the channel message decrypted
4146 correctly and also when private keys are set for the channel the
4147 receiver can decrypt the packet with several keys and check from
4148 the MAC which key decrypted the message correctly.
4150 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4151 lib/silccrypt/silccipher.[ch].
4153 * Added silc_hash_len to return the digest length into the
4154 lib/silcrypt/silchash.[ch].
4156 * Rewrote parts of Silc Channel Payload interface in the
4157 lib/silccore/silcchannel.[ch]. The encode function now also
4158 encrypts the packet and parse function decrypts it.
4160 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Fixed a minor formatting bug in the SKE's key material processing.
4163 It actually might have processed the keys wrong way resulting
4166 * Redefined the mandatory HMAC algorithms and added new algorithms.
4167 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4168 and hmac-md5 truncated to 96 bits. The mandatory is now
4169 hmac-sha1-96. Rest are optional (including the one that used
4170 to be mandatory). Rationale for this is that the truncated HMAC
4171 length is sufficient from security point of view and can actually
4172 make the attack against the HMAC harder. Also, the truncated
4173 HMAC causes less overhead to the packets. See the RFC2104 for
4176 * Added new [hmac] configuration section. The SKE used to use
4177 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4178 is of course wrong. The official names that must be proposed in
4179 the SKE are the ones defined in the protocol specification
4180 (hmac-sha1-96 for example). The user can configure any hmac
4181 using any hash function configured in the [hash] section. At
4182 least, the mandatory must be configured.
4184 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4186 * Added HMAC list to the SKE proposal list. It has now both
4187 hash algorithm list and HMAC list. This makes the protocol
4188 incompatible with previous versions. The SKE now seems to work
4189 the way it is supposed to work, for the first time actually.
4191 * Defined plain Hash algorithms to the protocol specification.
4194 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Implemented support for key agreement packets into the server.
4197 Added functions silc_server_key_agreement and
4198 silc_server_send_key_agreement. Other than these functions,
4199 server has nothing to do with this packet.
4201 * Added support for private message key packets into the server.
4202 Added functions silc_server_private_message_key and
4203 silc_server_send_private_message_key.
4207 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4208 called in the protocol's final callback instead in the END
4209 protocol state. This makes a little more sense and in the same
4210 time in client we can use the same protocol routines for normal
4211 key exchange and to key agreement packet handling as well.
4213 * Added to both client's and server's KE protocol context the
4214 SilcSKEKeyMaterial pointer to save the key material. We will
4215 bring the key material to the protocol's final callback by doing
4216 this. The final callback must free the key material.
4218 * Added SKE's packet_send callback into client's KE protocol
4219 context so that the caller can choose what packet sending function
4220 is used. This way we can use different packet sending when
4221 doing normal SKE when doing key agreement packet handling (in
4222 the key agreement packet handling we do not want to encrypt
4225 * Implemented the responder side of the key agreement routines
4226 in the client. The client can now bind to specified port and
4227 accept incoming key negotiation. The key material is passed
4228 to the application after the protocol is over.
4230 * Implemented the processing of incoming Key Agreement packet
4231 in the client. Added function silc_client_key_agreement to
4234 * Implemented the intiator side of the key agreement routines
4235 in the client. The client can now initiate key agreement with
4236 another remote client. The key material is passed to the
4237 application after the protocol is over.
4239 * Created client_keyagr.c to include all the key agreement
4242 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4243 SILC_TASK_CALLBACK except that it is not static.
4245 * Created client_notify.c and moved the Notify packet handling
4246 from the client.[ch] into that file.
4248 * Created client_prvmsg.c and moved all private message and
4249 private message key routines from the client.[ch] into that file.
4251 * Create client_channel.c and moved all channel message and
4252 channel private key routines from the client.[ch] into that file.
4254 * Changed silc_client_get_client_by_id_resolve to resolve with
4255 WHOIS command instead of IDENTIFY command, in the file
4256 lib/silclient/idlist.c.
4258 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Implemented the SKE's responder side to the Client library.
4262 * When FAILURE is received to the protocol do not trust it
4263 blindly. Register a timeout to wait whether the remote closes
4264 the connection as it should do it, only after that process the
4265 actual failure. This was changed to both client and server.
4267 * Added client_internal.h to include some of the structures
4268 there instead of client.h in lib/silcclient/.
4270 * Added function silc_task_unregister_by_callback to unregister
4271 timeouts by the callback function.
4273 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Some "Incomplete WHOIS info" errors has been appearing on the
4276 log files. Took away the entry->userinfo check from WHOIS
4277 reply sending. The entry->userinfo is now " " if client did not
4278 provide one. I thought this was fixed earlier but something
4279 is wrong still. Let's see if the error still appears.
4281 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Fixed a minor bug in the login when the channel key is
4284 re-generated in the server. It used to generate the key in
4285 wrong order and thus caused problems in the channel traffic.
4287 * Fixed a minor bug in channel key distsribution after
4288 KICK command. The key was not sent to the router even though
4291 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Added silc_ske_process_key_material_data as generic routine
4294 to process any key material as the SILC protocol dictates. The
4295 function is used by the actual SKE library but can be used by
4296 applications as well. This relates to the private message keys
4297 and the channel private keys since they must be processed the
4298 same way the normal SILC session keys. The protocol dictates
4299 this. Affected files: lib/silcske/silcske.[ch].
4301 Added also silc_ske_free_key_material to free the
4302 SilcSKEKeyMaterial structure.
4304 * Defined silc_cipher_set_key function to set the key for
4305 cipher without using the object's method function. The affected
4306 files: lib/silccrypt/silccipher.[ch].
4308 * Implemented silc silc_client_add_private_message_key,
4309 silc_client_add_private_message_key_ske,
4310 silc_client_del_private_message_key,
4311 silc_client_list_private_message_keys and
4312 silc_client_free_private_message_keys functions in the
4315 Added functions silc_client_send_private_message_key to send
4316 the Private Message Key payload and silc_client_private_message_key
4317 to handle incoming Private Message Key payload.
4319 * Added Cipher field to the Private Message Key payload to set
4320 the cipher to be used. If ignored, the default cipher defined
4321 in the SILC protocol (aes-256-cbc) is used.
4323 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Removed lib/silcclient/ops.h file.
4327 Redefined parts of the SILC Client Library API. Created new
4328 file silcapi.h that deprecates the ops.h file and defines the
4329 published Client Library API. Defined also private message key
4330 API and channel private key API into the file.
4332 This is the file that the application must include from the
4333 SILC Client Library. Other files need not be included by
4334 the application anymore.
4336 * Added new key_agreement client operation callback and also
4337 defined the Key Agreement library API for the application.
4339 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4342 is used by clients to request key negotiation between another
4343 client in the SILC network. If the negotiation is started it
4344 is performed using the SKE protocol. The result of the
4345 negotiation, the secret key material, can be used for example
4346 as private message key.
4348 Implemented the Key Agreement payload into the files
4349 lib/silccore/silauth.[ch].
4351 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Redefined ciphers for the SILC protocol. Added some new ciphers
4354 and defined the key lengths for the algorithms. Changed the
4355 code accordingly. The default key length is now 256 bits.
4357 * Fixed SKE key distribution function silc_ske_process_key_material
4358 when the key length is more than 128 bits. The default key
4359 length in SILC is now 256 bits.
4361 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4362 to indicate unsupported algorithm.
4364 * Renamed rijndael.c to aes.c and all functions as well.
4366 * Fixed a long standing channel key setting bug in client library.
4367 Weird that it has never surfaced before.
4369 * Fixed bug in channel deletion. If the entire channel is removed
4370 then it must also delete the references of the channel entry
4371 from the client's channel list as the client's channel entry and
4372 the channel's client entry share same memory.
4374 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Implemented CONNECT and SHUTDOWN commands in the client.
4378 * Implemented CLOSE command to the client.
4380 * Added the function silc_idlist_find_server_by_name into the
4381 files silcd/idlist.[ch].
4383 Added the function silc_idlist_find_server_by_conn into the
4384 files silcd/idlist.[ch].
4386 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * DIE command was renamed to SHUTDOWN. Updated the both code
4391 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4392 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4394 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4397 * Added function silc_server_create_connection function to create
4398 connection to remote router. My server implementation actually
4399 does not allow router to connect to normal server (it expects
4400 that normal server always initiates the connection to the router)
4401 so the CONNECT command is only good for connecting to another
4404 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4407 or some other client was kicked from the channel.
4409 Implemented the handling of the notify type to both client
4412 Implemented silc_server_send_notify_kicked to send the KICKED
4413 notify. It is used to send it to the server's primary router.
4415 * Implemented the KICK command into server and client.
4417 * Added `query' argument to the silc_idlist_get_client function
4418 to indicate whether to query the client from server or not if
4421 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4422 to indicate that the client is not channel founder.
4426 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * Removed the rng context from SilcPacketContext structure and
4429 changed that the packet routine uses the Global RNG API.
4431 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Added support for quit message that client can "leave" on the
4434 channel when it quits the SILC. It is ditributed inside the
4435 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4437 Added silc_server_free_client_data that will take the
4438 signoff message as argument.
4440 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4442 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Updated parts of the protocol specification to keep it up
4447 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4450 payloads in one packet.
4452 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4453 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4454 use now the new List flag.
4456 * Also deprecated the following packet types: REPLACE_ID,
4457 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4459 * Added list support for Notify packet in server.
4461 * Added silc_server_send_notify_channel_change to send the
4462 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4463 the silc_server_send_replace_id.
4465 * Added silc_server_send_notify_nick_change to send the
4466 NICK_CHANGE notify type. Deprecates the function
4467 silc_server_send_replace_id.
4469 * Added silc_server_send_notify_join to send the JOIN notify type.
4470 Deprecates the function silc_server_send_new_channel_user.
4472 * Added silc_server_send_notify_leave to send LEAVE notify type.
4473 Deprecates the function silc_server_send_remove_channel_user.
4475 * Added silc_server_send_notify_cmode and
4476 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4477 types. Deprecates the silc_server_send_set_mode function.
4479 * Added SERVER_SIGNOFF notify type to indicate that server has
4480 quit. This means that all clients on the channel from that
4481 server will drop. This can be also used when netsplit happens.
4483 Deprecated REMOVE_ID packet type since it is not needed anymore
4486 Added silc_server_send_notify_server_signoff to send the
4487 SERVER_SIGNOFF notify type. Deprecates the function
4488 silc_server_send_remove_id.
4490 Added also silc_server_send_notify_signoff to send the
4491 SIGNOFF notify type.
4493 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4494 SILC protocol from this day on. Changed the protocol
4495 specification as well.
4497 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4498 notify type. It is used between routers to notify about
4499 topic changes on a channel.
4501 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4504 * Partly updated the protocol specification to comply with the
4505 changes now made. It is still though a bit outdated.
4507 * The JOIN notify type now takes one extra argument <Channel ID>.
4508 The packet used to be destined to the channel but now the
4509 JOIN type may be sent as list thus it is impossible to
4510 destine it to any specific channel. By adding this argument
4511 it is again possible.
4513 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Added CREDITS file. The CHANGES and CREDITS file will appear
4516 in the distribution as well.
4518 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4521 types in the server's silcd/packet_receive.c.
4523 * Implemented CMODE and CUMODE to work in router environment.
4525 * Fixed minor encoding and decoding buglet from the
4526 lib/silccore/silcmode.c.
4528 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4531 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4533 * Changed all SilcConfigServer* and silc_config_server* to
4534 SilcServerConfig* and silc_server_config*, respectively.
4537 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Associated the ID (client or server ID) to the Authentication
4540 Payload to avoid any possibility of forging. Updated the
4541 protocol specification and the code accordingly.
4543 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * The RSA key length is now save to the RsaKey context in the
4546 key generation process in lib/silccrypt/rsa.c. The key length
4547 is now used to figure out the maximum size of the block allowed
4548 to be encrypted/signed.
4550 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4551 is equivalent to the silc_mp_mp2bin but does not allocate any
4554 * Changed silc_mp_mp2bin API to take length argument. If it is
4555 non-zero then the buffer is allocated that large. If zero, then
4556 the size is approximated using silc_mp_sizeinbase, which however
4559 * Created Global RNG API which is global RNG that application can
4560 initialize. After initializing, any routine anywhere in the
4561 code (including library) can use RNG without allocating a new
4562 RNG object. This was done to allow this sort of use of the
4563 RNG in code that has no chance to allocate RNG object. All
4564 applications currently allocate this and many routines in the
4565 library use this. Affected file lib/silccrypt/silcrng.[ch].
4567 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4568 it to use the Global RNG API.
4570 * Defined Authentication Payload into protocol specification that
4571 is used during SILC session to authenticate entities. It is
4572 used for example by client to authenticate itself to the server
4573 to obtain server operator privileges.
4575 Implemented this payload into the lib/silccore/silcauth.[ch].
4576 Implemented also routines for public key based authentication
4577 as the new protocol specification dictates.
4579 Moved definitions of different authentication methods from
4580 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4582 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4583 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4584 silc_pkcs_verify_with_hash functions into the file
4585 lib/silccrypt/silcpkcs.[ch].
4587 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * The client entry's userinfo pointer must be always valid.
4590 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4591 will fail since it requires the userinfo. Now, the userinfo
4592 is allocated as "" if actual userinfo does not exist. Actually,
4593 it must exist and it is totally Ok to drop client connections
4594 that does not announce the userinfo. However, we will make
4595 this workaround for now.
4597 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4598 to return the remote port by socket.
4600 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4603 SILC_SERVER_PENDING_EXEC and added an new macro
4604 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4605 data or when error occurs while processing the pending command.
4607 Added new argument `destructor' into silc_server_command_pending
4608 and to the SilcServerCommandPending object. This destructor is
4609 now called after calling the pending callback or if error occurs
4610 immediately. If error occurs the actual pending callback won't
4611 be called at all - only the destructor. The destructor may be
4612 NULL if destructor is not needed.
4614 All this applies for client library code as well. Similar
4615 changes were made there as well for the pending commands.
4617 In the client, the application must now allocate the
4618 SilcClientCommandContext with the silc_client_command_alloc
4621 * Added reference counter to the SilcServerCommandContext. Added
4622 function silc_server_command_alloc and silc_server_command_dup
4625 Same type of functions added to the client library for the same
4628 * Removed the cmd_ident from IDListData away since it is now
4629 global for all connections. It is the command identifier used
4630 in command sending and with pending commands. The affected file
4633 * Added reference counter to the SilcSocketConnection objecet to
4634 indicate the usage count of the object. The object won't be
4635 freed untill the reference counter hits zero. Currently only
4636 server uses this, and client ignores it. The client must be
4637 set to use this too later. The affected files are
4638 lib/silccore/silcsockconn.[ch]. Added also the function
4639 silc_socket_dup to increase the reference counter.
4641 This was mainly added because it is possible that the socket
4642 is removed underneath of pending command or other async
4643 operation. Now it won't be free'd and proper DISCONNECTING
4644 flags, etc. can be set to avoid sending data to connection that
4645 is not valid anymore.
4647 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4648 the connection. After that it sets SILC_SET_DISCONNECTED.
4649 It is, however, possible that the socket data is not still freed.
4650 The silc_server_packet_process now checks that data is not
4651 read or written to connection that is DISCONNECTED. The socket
4652 get's freed when the reference counter hits zero.
4654 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Changed the client operation API: channel_message operation's
4657 `sender' is now the client entry of the sender, not the nickname
4658 and the `channel' is the channel entry, not the channel name.
4660 In the private_message operation the `sender' is now also the
4661 client entry of the sender not the nickname.
4663 Affected file is lib/silcclient/ops.h and all applications
4664 using the client operations.
4666 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Moved the calling of ops->connect() from connect_to_server_final
4669 into receive_new_id functin since that is the point when the
4670 client is actually allowed to send traffic to network. The
4671 affected file is lib/silcclient/client.c.
4673 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4676 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4677 (if needs broadcasting) instead of broadcasting the packets one
4678 by one which would make a burst in the network traffic.
4680 * Added `broadcast' argument to the functions in silcd/server.[ch]
4681 silc_server_create_new_channel[_with_id] to indicate whether
4682 to send New Channel packet to primary router.
4684 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added new function into the silcd/server.[ch] files:
4687 silc_server_create_new_channel_with_id to create new channel with
4688 already existing Channel ID.
4690 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4691 lib/silccore/silcpacket.h. This packet is used t send list of
4692 Set Mode payloads inside one packet. Server uses this to set
4693 the modes for the channels and clients on those channels, that it
4694 announced to the router when it connected to it. The protocol
4695 specification has been updated accordingly.
4697 * The silc_server_new_channel did not handle the packet coming
4698 from normal server as it normally does not send that. However,
4699 when it announces its channels it does send it. Implemented
4700 the support for that.
4702 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4703 into the file lib/silccore/id.h.
4705 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Fixed memory leaks in the functions silc_idlist_del_client,
4708 silc_idlist_del_channel and silc_idlist_del_server in the file
4709 silcd/idlist.c. All of those leaked like a sieve.
4711 * Fixed some small memory leaks in the client's function
4712 silc_client_notify_by_server.
4714 * Added functions into silcd/server.c: silc_server_announce_clients,
4715 silc_server_announce_channels and silc_server_announce_server.
4716 These functions are used by normal and router server to announce
4717 to its primary router about clients, channels and servers (when
4718 router) that we own. This is done after we've connected to the
4721 These functions effectively implements the following packet types:
4722 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4723 and SILC_PACKET_NEW_ID_LIST.
4725 * Added new functions into the silcd/packet_receive.[ch]:
4726 silc_server_new_id_list, silc_server_new_channel_list and
4727 silc_server_new_channel_user_list to handle the incoming
4728 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4730 * Added support of changing Channel ID in the function
4731 silc_server_replace_id. If the server that announces a channel
4732 to the router already exists in the router (with same name but
4733 with different Channel ID), router is responsible to send
4734 Replace ID packet to the server and force the server to change
4735 the Channel ID to the one router has.
4737 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4738 client that the Channel ID has been changed by the router. The
4739 normal server sends this to the client. Client must start using
4740 the new Channel ID as the channel's ID.
4742 Implemented handling of this new type into lib/silcclient/client.c
4743 into the function silc_client_notify_by_server.
4745 * Added new function silc_idlist_replace_channel_id into the files
4746 silcd/idlist.[ch] to replace the Channel ID.
4748 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Call silc_server_command_identify_check always when processing
4751 the IDENTIFY command in silcd/command.c
4753 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4756 send keepalive packets. The packet can be sent by clients,
4757 servers and routers.
4759 Added function silc_socket_set_heartbeat into the file
4760 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4761 If not set, the heartbeat is not performed. The actual
4762 heartbeat is implemented in the low level socket connection
4763 library. However, application is responsible of actually
4766 Added silc_server_send_heartbeat to send the actual heartbeat
4767 packet into silcd/packet_send.[ch]. Server now performs
4768 keepalive with all connections.
4770 * Added silc_task_get_first function into lib/silcutil/silctask.c
4771 to return the timeout task with shortest timeout. There was a bug
4772 in task unregistration that caused problems. TODO has been
4773 updated to include that task system must be rewritten.
4775 * The client library will now resolve the client information when
4776 receiving JOIN notify from server for client that we know but
4777 have incomplete information.
4779 * Rewrote parts of silc_server_remove_from_channels and
4780 silc_server_remove_from_one_channel as they did not remove the
4781 channel in some circumstances even though they should've.
4783 * Encryption problem encountered in server:
4785 The LEAVE command used to send the Channel Key packet to the
4786 router immediately after generating it. However, the code
4787 had earlier sent Remove Channel user packet but not immediately,
4788 ie. it was put to queue. The order of packets in the router
4789 was that Channel Key packet was first and Remove Channel User
4790 packet was second, even though they were encrypted in the
4791 reverse order. For this reason, MAC check failed. Now, this
4792 is fixed by not sending the Channel Key packet immediately but
4793 putting it to queue. However, this is more fundamental problem:
4794 packets that are in queue should actually not be encrypted
4795 because packets that are sent immediately gets encrypted
4796 actually with wrong IV (and thus MAC check fails). So, packets
4797 that are in queue should be encrypted when they are sent to
4798 the wire and not when they put to the queue.
4800 However, the problem is that the current system has not been
4801 designed to work that way. Instead, the packet is encrypted
4802 as soon as possible and left to the queue. The queue is then
4803 just purged into wire. There won't be any fixes for this
4804 any time soon. So, the current semantic for packet sending
4807 o If you send packet to remote host and do not force the send
4808 (the packet will be in queue) then all subsequent packets to the
4809 same remote host must also be put to the queue. Only after the
4810 queue has been purged is it safe again to force the packet
4813 o If you send all packets immediately then it safe to send
4814 any of subsequent packets through the queue, however, after
4815 the first packet is put to queue then any subsequent packets
4816 must also be put to the queue.
4818 Follow these rules and everything works fine.
4820 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Added new function silc_server_remove_clients_by_server to
4823 remove all client entries from ID list when the server connection
4824 is lost. In this case it is also important to invalidate all
4825 client entires as they hold the invalid server entry. This
4826 fixes fatal bug when server has lost connection and will reconnect
4829 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Made some sanity checks to silc_server_daemonise like to check
4832 whether the requested user and group actually exists.
4834 * Added sanity check to SKE's silc_ske_responder_finish to check
4835 that the public and private key actually is valid.
4837 * Invalidate the client's nickname when receiving Replace ID
4838 packet and the Client ID is being replaced. This means that the
4839 server will query the nickname if someone needs it (client)
4842 * Sort the ID Cache in client library when the ID Cache data
4843 has changed (needs sorting).
4845 * Do not allow for SILC client to create several connections to
4846 several servers. The client does not support windows right now
4847 and generating multiple connections causes weird behaviour.
4849 Irssi-silc client does support windows and can handle several
4850 connections without problems, see: www.irssi.org and SILC plugin.
4852 * Fixed some places where client was added to the IDList. The
4853 rule of thumb is following (in order to get everything right):
4854 If the client is directly connected local client then the
4855 `connection' argument must be set and `router' argument must be
4856 NULL to silc_idlist_add_client function. If the client is not
4857 directly connected client then the `router' argument must
4858 bet set and the `connection' argument must be NULL to the
4859 silc_idlist_add_client function.
4861 * The funtion silc_server_packet_send_local_channel actually did
4862 not check whether the client was locally connected or not. It
4863 does that now. Fixed a bug related to LEAVE command.
4865 * Fixed Remove Channel User payload parsing bug in server's
4866 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4868 * The server's silc_server_save_channel_key now checks also the
4869 global ID list for the channel as it might not be in the local
4870 list. Fixed a bug related to LEAVE command.
4872 * Is this the end of the [<unknown>] buglet that has been lurking
4873 around for a long time? A little for loop fix in server's
4874 silc_server_command_whois_parse that is used by both IDENTIFY
4875 and WHOIS command. At least, this was a clear bug and a cause
4876 of one type of [<unknown>] buglet.
4878 * WHOIS and IDENTIFY commands call the function
4879 silc_server_command_[whois/identify]_check function even if
4880 we are not router server.
4882 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added --with-gmp configuration option. If set the GMP
4885 is always compiled in the SILC source tree. If not set then
4886 it is checked whether the system has the GMP3 installed. If
4887 it has then the GMP won't be compiled (the system's headers
4888 and library is used), if it doesn't have it then the GMP is
4889 compiled in the SILC source tree.
4891 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Changed RSA private exponent generation to what PKCS #1
4894 suggests. We try to find the smallest possible d by doing
4895 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4896 not security fix but optimization.
4898 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Added new config entry [Identity] to fork the server and run
4901 it as specific user and group. A patch from Bostik.
4903 * Imported Dotconf configuration library into lib/dotconf.
4904 This will be used to create the SILC configuration files later.
4905 It will appear in the distsribution after this commit.
4907 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * A big code auditing weekend happening. Auditing code for
4910 obvious mistakes, bugs and errors. Also, removing any code
4913 Removed files for being obsolete:
4915 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4916 inline in the file lib/silcutil/silcbuffer.h)
4918 o lib/silcutil/silcbufutil.c (the header has inline versions)
4920 Changed code to fix possible error conditions:
4922 o The buffer formatting routines now check that the destination
4923 buffer really has enough space to add the data. This applies for
4924 both buffer formatting and unformatting
4925 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4926 unformatting was changed to accomodate following rules:
4927 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4928 sent to the function while XXX_*STRING will not allocate or copy
4929 the data into the buffer. Instead it sets the pointer from the
4930 buffer into the pointer sent as argument (XXX_*STRING used to
4931 require that the pointer must be allocated already). This change
4932 makes this whole thing a bit more consistent and more optimized
4933 (note that the data returned in the unformatting with XXX_*STRING
4934 must not be freed now). The routines return now -1 on error.
4936 o Tried to find all code that use buffer_format and buffer_unformat
4937 and added return value checking to prevent formatting and
4938 especially unformatting errors and possible subsequent fatal
4941 o Changed ske->x and ske->KEY to mallocated pointers in
4942 lib/silcske/silcske.h. Fixed possible data and memory leak.
4944 o Added return value checking to all *_parse* functions. Fixed
4945 many memory leaks as well.
4947 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4948 so that buffer overflows would not happen. All code now also
4949 checks the return value as it can fail.
4951 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Added reconnection support to server if the normal server looses
4954 its connection to the router (for example if router is rebooted).
4955 The server performs normal reconnection strategy implemented
4956 to the server. Affected file silcd/server.c.
4958 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Added new packet type SILC_PACKET_SET_MODE that is used to
4961 distribute the information about changed modes (for clients,
4962 channels and clients channel modes) to all routers in the
4963 network. Updated the protocol specification accordingly.
4965 Added functions into silcd/packet_send.c and
4966 silcd/packet_receive.c: silc_server_send_set_mode,
4967 silc_server_set_mode.
4969 Added new files silcmode.[ch] into lib/silccore that implements
4970 the encoding and decoding of Set Mode Payload. Added new type
4971 SilcSetModePayload. Moved the definitions of different modes
4972 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4974 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Oops, a little mistake in server's connection authentication
4977 protocol. The protocol is not ended with FAILURE but with
4978 SUCCESS if the authentication is Ok. :) Affected file is
4981 * Implemented NICK_CHANGE notify handling in server in the file
4982 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4983 the local clients on the channel. After the changing nickname
4984 in router environment snhould work and the [<unknown>] nickname
4985 should appear no more.
4987 The silc_server_replace_id function that receives the Replace ID
4988 payload now sends the NICK_CHANGE notify type also in the file
4989 silcd/packet_receive.c
4991 * Changed WHOIS and IDENTIFY command to support the maximum amount
4992 of arguments defined in protocol specs (3328 arguments). This
4993 fixed a bug that caused problems when there were more than three
4996 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Added extra parameter, command identifier, to the
4999 silc_client_send_command so that explicit command identifier
5002 Changed that ID list routines uses specific command identifier
5003 when sending WHOIS/IDENTIFY requests to the server so that they
5004 can be identified when the reply comes back.
5006 Affected files lib/silcclient/command.[ch],
5007 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5009 * Added `sender' argument to silc_server_packet_send_to_channel
5010 to indicaet the sender who originally sent the packet to us
5011 that we are now re-sending. Ignored if NULL. Affected file
5012 silcd/packet_send.[ch].
5014 * Added some server statistics support in silcd/server_internal.h
5015 SilcServerStatistics structure and around the server code. Also
5016 send some nice statistics information when client is connecting
5019 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Fixed channel ID decoding in server's JOIN command reply in
5022 silcd/command_reply.c
5024 * Fixed braodcasting of replace ID payload to not to send it if
5025 we are standalone server in silcd/packet_receive.c.
5027 * Fixed all channel message sending routines to not to send
5028 packets to clients that has router set, since they are routed
5029 separately in the same function earlier. Affects file
5030 silcd/packet_send.c and all channel packet sending functions.
5032 * In USERS reply, res_argv[i] are not allocated, the table
5033 is allocated. Thus changed that free the table, not its
5036 * In server's whois_check and identify_check if the client is
5037 locally connected do not send any WHOIS commands - they are not
5040 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Fixed some minor bugs in client when sending WHOIS command. The
5043 arguments was in wrong order.
5045 * Removed statis function add_to_channel from server in
5046 silcd/command.c that was previously used with the joining but
5049 * Tested USERS command in router environment successfully with two
5050 routers, two servers and two clients.
5052 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Reorganized the USERS command and command reply in client library
5055 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5056 When the command is given by user we register a pending command
5057 callback that will reprocess the command after the reply has been
5058 received from the server. When reprocessing the packet we then
5059 display the information. Thus, the USERS information is displayed
5060 now in the command callback instead of in the command reply
5061 callback. The processing of the command is same as previously
5062 when server has sent the command reply in the JOINing process.
5064 * Added to USERS command in silcd/command_reply.c to join the client,
5065 we didn't use to know about, to the channel after we've created
5066 a client entry for it. Also, for clienet we did know already still
5067 check whether it is on the channel or not and add it if not.
5069 * Removed silc_server_command_join_notify as the function and its
5072 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Changed the client's pending command handling to the same as the
5075 server's pending command handling. It is also now possible to
5076 execute command reply functions from other command reply
5077 function as the function callbacks for commands and command
5078 replies are one and same. The pending commands are not static
5079 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5080 in client connection context. Thus, pending commands are server
5081 connection specific as it is convenient.
5083 Changed the function silc_client_command_pending and
5084 silc_client_command_pending_del and added new function
5085 silc_client_command_pending_check. Removed the
5086 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5089 * Added cmd_ident, current command identifier, to the client
5090 connection context in lib/silcclient/client.h to keep track on
5091 command identifiers used in command sending. Client's command reply
5092 function handling now supports the mandatory command identifiers.
5094 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5095 funtions in client to fully support pending command callbacks.
5097 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5098 as one of the arguments to the application in the command reply
5101 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5102 before first releasing SILC but came back. Now it is removed again
5103 and should come back nomore. The FORWARDED flag was used only
5104 by the JOINing procedure by forwarding the command packet to router.
5105 Now, the JOINing procedure has been changed to more generic (due
5106 to various router environment issues) and FORWARDED is not needed
5107 anymore for anything. The protocol specification is yet to be
5110 Now, removed silc_server_packet_forward from server and the flag
5111 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5113 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Renamed NAMES command to USERS command. The NAMES was named that
5116 due to historical reasons. Now it is renamed. Also, rewrote
5117 parts of the USERS command. The nickname list is not sent anymore
5118 by the server. Only Client ID and mode lists are sent in the USERS
5119 command. Changed this also to the protocol specification.
5121 The client now resolves the names and stuff after it receives
5122 the USERS list from the server when joining to the channel.
5124 * WHOIS and IDENTIFY commands has been changed to support multiple
5125 Client ID's per command. One can now search for multiple users
5126 in the network by sending only one WHOIS or IDENTIFY command.
5127 Changed the code and the protocol specifications.
5129 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5130 uses silc_server_command_whois_parse to parse the request. */
5132 * If normal server, do not parse the WHOIS and IDENTIFY requests
5133 before sending it to the router. Saves some time.
5135 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Fixed JOIN command on client library. Wrong number of arguments
5138 used to crash the client.
5140 * Added silc_server_channel_has_global function to check whether
5141 channel has global users or not.
5143 * Added silc_server_channel_has_local function to check whether channel
5144 has locally connected clients on the channel.
5146 * The silc_server_remove_from_one_channel now checks whether the
5147 channel has global users or not after given client was removed from
5148 the channel. It also checks whether the channel has local clients
5149 on the channel anymore. If it does not have then the channel entry
5150 is removed as it is not needed anymore.
5152 * The silc_server_notify now checks on JOIN notify whether the joining
5153 client is one of locally connected or global. If it is global then
5154 the channel has now global users on the channel and that is marked
5155 to the channel entry. Also, it now saves the global client to
5156 global list who is joining and JOINs it to the channel. This is
5157 for normal server, that is.
5159 Changed silc_server_send_notify_on_channel,
5160 silc_server_packet_relay_to_channel and
5161 silc_server_packet_send_to_channel check if we are normal server
5162 and client has router set (ie. global client) do not send the
5163 message to that client, as it is already routed to our router.
5165 * Implemented LEAVE notify type handling in silc_server_notify
5168 * Tested LEAVE command in router environment successfully. Tested
5169 with two routers, two servers and two clients.
5173 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5175 * Implemented SIGNOFF notify type handling in silc_server_notify
5178 * silc_server_remove_id now removes the client entry from all channels
5179 it has joined and thusly sends SIGNOFF notify type.
5181 * Rewrote the NAMES list generation in server by removing two excess
5182 loops. The lists are created now inside one loop.
5184 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * silc_server_remove_channel_user checks now also global list
5187 for channel and client.
5189 * silc_server_new_channel_user checks now both local and global
5190 list for channel and client. Fixed a bug in client id decoding.
5191 Used to decode wrong buffer.
5193 * silc_server_channel_message checks now both local and global
5194 list for channel entry.
5196 * Tested channel joining (hence JOIN) in router environment
5197 successfully. Tested with two routers, two servers and two
5200 * Tested channel message sending in router environment successfully.
5202 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Added silc_server_save_channel_key into server.[ch] to save the
5205 received channel key in Channel Key payload processing. It is
5206 also used in JOIN command reply handling.
5208 Equivalent function silc_client_save_channel_key added into
5209 client.[ch] into client library.
5211 * Changed JOIN command reply to send information whether the channel
5212 was created or not (is existing already) and the channel key
5213 payload. Changed protocol specs accordingly.
5215 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5216 the request was sent by ID and not by nickname. Crashed on
5219 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5222 now correctly save the received data.
5224 * silc_server_free_sock_user_data now notifies routers in the
5225 network about entities leaving the network.
5227 At the same time implemented functions silc_server_remove_id
5228 and silc_server_send_remove_id to receive and send REMOVE_ID
5229 packets. The packet is used to notify routers in the network
5230 about leaving entities. The ID removed will become invalid in
5233 * Added function silc_idlist_del_server into server. Removes and
5234 free's server entry from ID list.
5236 * silc_server_private_message function now checks, if we are router,
5237 that the destination ID really is valid ID, naturally.
5239 * In router when NEW_ID packet is received (for new client) the
5240 hash of the Client ID is saved in the ID Cache but the
5241 client->nickname is set to NULL, instead of putting the hash
5244 IDENTIFY command now also checks that client->nickname must be
5245 valid. If it is not if will request the data from the server who
5246 owns the client. Added new function
5247 silc_server_command_identify_check.
5249 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5250 to set the command to already allocated Command Payload.
5252 * Tested private message sending in router environment with two
5253 routers, two servers and two clients. Fixed minor bugs and now
5256 * Fixed segfault from client's NAMES command. Used to crash if
5259 * Forwarded packets must not be routed even if it is not destined
5260 to the receiver. Changed server code comply with this.
5262 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added `require_reverse_mapping' boolean value to ServerParams
5265 structure. If TRUE (not default) the server will require that
5266 the connecting host has fully qualified domain name.
5268 If the reverse mapping is not required and hostname could not be
5269 found the IP address is used as hostname.
5271 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Implemented version string checking to both client and server.
5274 The check is incomplete currently due to the abnormal version
5275 strings used in development version of SILC.
5277 * Changed all command functions in server to use the new
5280 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Changed char *data to unsigned char *data in ID Cache system to
5283 support binary data as ID Cache data. Changed code to support
5284 binary data in lib/silccore/idcache.c.
5286 * Renamed silc_server_packet_relay_command_reply to
5287 silc_server_command_reply as it is normal packet receiving
5288 function. Rewrote the function to accept command replys for
5289 servers and not only for clients.
5291 * Mark remote router always as registered server if we are connecting
5292 to it. Otherwise, commands sent by the router to us are ignored.
5294 * All ID List find routines now returns the ID Cache Entry pointer
5295 as well if requested.
5297 * WHOIS command works now in router environment, tested with two
5298 routers, two servers and two clients.
5300 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5301 in router environment (as it is almost equivalent to WHOIS) but
5302 hasn't been tested thoroughly. Added new functions:
5304 silc_server_command_identify_parse
5305 silc_server_command_identify_send_reply
5306 silc_server_command_identify_from_client
5307 silc_server_command_identify_from_server
5309 * Disabled route cache adding because adding two different ID's with
5310 same IP replaces the old cache entry thus giving wrong route.
5311 The entry->router->connection is always the fastest route anyway
5312 so route cache may not be needed. Of course, new routes maybe
5313 established after receiving the ID when the entry->router->connection
5314 might not be anymore the most optimal.
5316 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Add route cache for received ID for fast routing.
5320 * Added silc_server_packet_route to route received packet on router
5321 that is not destined to us.
5323 * Renamed silc_server_get_route to silc_server_route_get.
5325 * Added id_string and id_string_len fields into SilcServer to
5326 include encoded ServerID for fast comparing without excess
5327 encoding of the ID's.
5329 * Cleaned up WHOIS command on server side. Added following static
5332 silc_server_command_whois_parse
5333 silc_server_command_whois_check
5334 silc_server_command_whois_send_reply
5335 silc_server_command_whois_from_client
5336 silc_server_command_whois_from_server
5338 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5339 arguments in command replies. All command functions should be
5340 updated to use this macro.
5342 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Minor typo fixes on command reply handling on server.
5346 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Added silc_server_command_add_to_channel internal routine to add
5349 the client to the channel after router has created the channel and
5350 sent command reply to the server.
5352 * Added generic silc_server_send_command to send any command from
5355 * Use static buffer with ID rendering instead of duplicating data.
5357 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Fixed a channel user mode bug when joining to a channel server gave
5360 everybody channel founder rights, oops.
5362 * We mark ourselves as the router of the incoming server connection
5363 if we are router ourselves. This way we can check in some packet
5364 sending functions whether it is locally connected server. For
5365 incoming router connections we put NULL.
5367 * For router sending packets locally means now always sending the
5368 packet cell wide; to local clients and local servers. For normal
5369 server sending packet locally means sending it to only local
5372 * Fixed the JOIN command to really work in router environment. If the
5373 channel is created it is always created by the router. Router is
5374 also responsible of making the initial joining to the channel,
5375 sending JOIN notify to the sending server and distributing
5376 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5377 does not exist server doesn't do anything else but forward the
5378 command to the router which performs everything.
5380 * Added silc_server_send_channel_key function to send the Channel Key
5383 * Added silc_server_create_channel_key to create new channel key. The
5384 channel key is now re-generated everytime someone joins or leaves
5385 a channel, as protocol dictates. Note: channel->key_len is the
5388 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5391 packet_receive.[ch] to separate packet sending and receiving
5392 routines. The server.[ch] now includes everything else including
5393 actual packet processing (writing and reading data) and other
5396 Renamed silc_server_private_message_send_internal to
5397 silc_server_send_private_message. The routine is still though
5398 used only to relay private messages as server does not send
5399 private messages itself.
5401 Renamed silc_server_new_channel to silc_server_create_new_channel
5402 and added new function sicl_server_new_channel that handles the
5403 incoming New Channel packet. Added also new sending function
5404 silc_server_send_new_channel to send New Channel Payload.
5406 * Added new function silc_server_notify to process incoming notify
5407 packet to the server/router. Server may then relay the notify
5408 to clients if needed.
5410 * Added new function silc_server_new_channel_user to process incoming
5411 New Channel User packet. Router will redistribute the packet and
5412 send JOIN notify to its local clients and locally connected servers
5413 if needed. Normal server will send JOIN notify to its local client
5414 on same channel when received this packet. Added also corresponding
5415 sending function silc_server_send_new_channel_user to sent the
5418 * Added boolean route argument to send_notif_to_channel and
5419 packet_send_to_channel functions to attempt to route the packet
5420 if it is TRUE and send only locally if it is FALSE.
5422 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * silc_server_replace_id now broadcasts the received replace ID
5425 packet if it is not broadcast packet already. The router must
5426 broadcast to inform other routers about changed ID.
5428 * Added backpointer to server's router into SilcServer context in
5429 silcd/server_internal.h.
5431 * Fixed silc_server_packet_broadcast to send correct broadcast
5434 * The channel key is now distributed to the local client as soon
5435 as it is received from the router (in router environment) so that
5436 no other packet may be sent for the channel until client has
5439 * silc_server_remove_channel_user now broadcasts the received
5440 Remove Channel User packet if it is not broadcast packet already.
5441 The router must broadcast to inform other routers about removed
5444 * Added users field into SilcPacketContext that is a reference count
5445 of the context. One can increase the reference count by calling
5446 silc_packet_context_dup which is now changed to just increase the
5447 reference count instead of duplicating the data. The reference
5448 count is decresed by calling silc_packet_context_free that will
5449 free the data after the reference count hits zero.
5451 For now on the packet context and everything allocated into it
5452 (including the raw packet from network) must be freed by calling
5453 the new silc_packet_context_free function. Added also new function
5454 silc_packet_context_alloc that must be used now to allocate the
5455 context. This also means that if a routine is asynchronous from
5456 silc_[client/server]_packet_parse_type the packet context must
5457 be duplicated by calling silc_packet_context_dup. Otherwise it
5458 gets free'd after silc_[client/server]_packet_parse_type returns.
5459 Also, one must remember that if packet is duplicated then its
5460 reference count must be decresed by calling the free function as
5461 many times as it was duplicated.
5463 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5464 from both client and server.
5466 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Made joining to a channel working in router environment.
5470 * Cleaned up JOIN command on server side and create function
5471 silc_server_command_join_channel internal routine to make the
5474 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Changed silc_command_pending list to SilcDList. Also, added
5477 `ident' field to SilcServerCommandPending structure to identify
5478 the reply and to call correct callback.
5480 Added silc_server_command_pending_check function to replace the
5481 corresnponding macro. The silc_command_pending list is not
5484 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5485 to set identifier to previously allocated Command Payload. It
5486 is used to set identifier for command when resending Command
5489 * Added silc_command_payload_encode_payload to encode Command
5490 Payload buffer from SilcCommandPayload structure.
5492 * Added silc_argument_payload_encode_payload to encode Argument
5493 payload buffer from SilcArgumentPayload structure.
5495 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Changed WHOIS command to support router connection on server side.
5498 The whois request is always sent to router unless the server is
5499 standalone server. After server has received the reply from the
5500 router will it send the reply to the client.
5502 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5503 broadcast received broadcast packet. The function is used only
5504 by router. The broadcast packet is always sent to the router's
5507 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5508 render given ID to printable string, for log files for example.
5510 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Made basic router to router connections working. At least they
5513 can now connect to each other but nothing really works the way
5514 they are supposed - yet.
5516 * Added new initiator token to RouterConnection configuration
5517 file in silcd/serverconfig.[ch]. It is used to tell whether we
5518 are the initiator to the remote router or whether we'll expect
5519 the other end to connect.
5521 * Moved registering of listener task to silc_server_init, hence
5522 the server starts listenning as soon as it is run, even if it
5523 does not have connections to other routers. Let's see how well
5526 * Changed default connection retry timeouts for more suitable in
5529 * Removed cipher and such arguments from silc_idlist_add_client
5530 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5531 Added new function silc_idlist_add_data to add the keys and stuff
5534 * Added SilcIDListData structure and added it to SilcClientEntry
5535 and SilcServerEntry as their first field in the structure. This
5536 way we can explicitly cast the ID entries to the SilcIDListData
5537 structure and get common data for the entries. In past, we had
5538 to first check what type of connection it is and then cast it to
5539 correct ID entry type. Now, we can directly cast the opaque
5540 pointer to the SilcIDListData (no matter what ID entry it actually
5541 is) and get the data needed.
5543 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5546 in some circumstances even if threre were timeout tasks, though not
5547 IO tasks, but tasks anyway. Now fixed.
5549 * Defined SilcServerConnection structure to hold connection specific
5550 stuff about directly connected servers and routers. The definition
5551 is currently in silcd/server_internal.h. I thought about having
5552 a bit more important role fro this struct but for now it is used
5553 only when connecting to other server (or router actually).
5555 * Added connecting retry support in server when connecting to
5556 router(s). The retry feature implement exponential backoff
5557 algorithm. Also, added SilcServerParams structure to hold default
5558 parameters for server. For now, it include these retry settings
5559 and are hard coded. After server is moded to be as Silc Server
5560 Library this structure will be more important.
5562 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Changed client librarys channel->clients table to SilcList and
5565 changed code accordingly.
5567 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Changed client's channel table to SilcList and changed code
5570 accordingly. Also changed SilcChannelClientEntry to include back-
5571 pointer to the channel so that client entry can use that structure
5572 as list as well and we have fast cross-reference to the channel.
5573 This change dramatically decreased the complexity of channel
5574 handling with client entry and vice versa (removed one extra
5575 loop when searching for channel entry from many functions).
5577 * Changed server->sim from table to SilcDList and changed code
5580 * NAMES command can now be used from user interface. It will show
5581 the user list on the channel, neatly.
5583 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5584 Code now saves realname of the user if it becomes available.
5586 * Renamed configure.in to configure.in.pre and made ./prepare
5587 script to automatically add correct version string to
5588 configure.in which it creates from configure.in.pre.
5590 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * NAMES command reply now shows users mode with the nickname when
5595 * Moved silc_client_ch[u]mode[_char] functions from
5596 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5597 place sucks, they are utility functions and should be in some
5600 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5602 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5605 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added TRQ (efficient deque and list library) into lib/trq. This is
5610 a very good list library that is currently used in the SILC. Defined
5611 SilcList API over the library because I didn't like the API very
5612 much. See lib/trq/silclist.h for the API and examples of how to
5613 use the API. Fixed various places in the code to use the new
5614 SilcList API. The SilcList is meant for lists that has a structure
5615 already defined as a list. It is not suitable to add just some
5616 context to the list (in TRQ, the context is the list actually).
5618 So, I defined SilcDList that can be used for the purpose where
5619 predefined list structure does not exit. This can be used as
5620 such list. Now some context just can be added to the SilcDList.
5621 Currently this list is not used in the SILC just yet, though there
5622 are a lot places where this can replace dynamically allocated
5623 tables and I will fix these places, later, to use SilcDList.
5624 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5625 and use TRQ internally).
5627 Also fixed some annoying warning messages that the original TRQ
5628 code generated. Also minor changes to TRQ's Makefile.in.
5630 * Added support for querying by Client ID to both WHOIS and
5631 IDENTIFY commands into server, as required by the protocol.
5633 * Removed method function pointers from SilcBuffer structure. They
5634 weren't used to anything and just increased the context size for
5635 no good reason. This change also made silc_buffer_alloc and
5636 silc_buffer_free functions inline functions.
5638 * Disabled command flooding detection support until it's fixed so
5639 that it accepts commands in but does not execute them more than once
5642 * Added silc_net_localhost(), to return local hostname, into
5643 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5644 that must be initialized before calling silc_client_init.
5646 * Added new function: silc_server_send_notify_on_channels to send
5647 notify messages to all channels client has joined. It is assured
5648 that the message is sent only once per client.
5650 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5651 lib/silcutil/silcutil.[ch] as silc_format function. The new
5652 function is generic and is used by server as well, not only by
5653 the logging routines.
5655 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5656 the provided version string was not acceptable. Added new function:
5657 silc_ske_check_version into lib/silcske/silcske.h. The function
5658 must be implemented by the application (client or server) and it
5659 does not reside in the SKE library. The function checks the version
5660 string remote end sent.
5662 * Added back pointers (to opaque context and to SilcSocketConnection)
5663 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5665 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5666 duplicate packet context structure.
5668 * Changed `notify' client operation to send same arguments as client
5669 receives from server except for ID's. ID's are mapped to correct
5670 ID entry and that is returned. Also, if channel entry is not sent
5671 by server but the notify is for channel the channel entry is sent
5672 to application (otherwise application doesn't know that it is for
5673 channel (library gets it from packet's Destination ID)).
5675 * Added silc_client_remove_from_channels into client library to
5676 remove a client from all channels it has joined to. Used when
5677 received SIGNOFF notify from server. Added also new function
5678 silc_client_replace_from_channels to replace old ID entry with
5679 new ID entry on all channels. Used when received NICK_CHANGE
5682 * Fixed ID Cache list handling in silc_idlist_get_client in
5683 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5684 to get (or query) client by ID.
5686 * Updated TODO list.
5688 * Added connection authentication status message defined by the
5689 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5690 support for these into the code in client and server side.
5692 * Added generic function silc_client_send_command to send any command
5693 with variable argument list. Application should use this function
5694 to send commands if the command functions provided by the library
5695 does not suite for the application's user interface needs.
5697 * Added new `failure' client operation. Application is notified about
5698 received failure packet if client is executing a protocol. In this
5699 case the protocol's execution has failed.
5701 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5702 is required by the protocol.
5704 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5705 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5708 * Added status flag to SilcSKE object to indicate realtime status
5709 of the SKE protocol.
5711 * Application receives now exactly same command reply arguments as
5712 the library receives from server. However, if ID is received the
5713 corresponding ID entry is returned to the application (eg. Client
5714 ID is mapped to correct SilcClientEntry entry and that is returned).
5715 Changed command_reply client operation due to this change.
5717 * Changed all ID's in commands and in command replys as ID Payloads.
5718 Change affected both client and server side codes.
5720 All ID's sent in SILC network (with execption of ID's in SILC
5721 Packet header) are sent in ID Payload to support variable length
5724 * Server now notifies nick changes and notifies all clients on
5725 the channels about the new nickname (about the new Client ID,
5728 * Implemented CMODE command to change channel modes. Supports all
5729 channel modes defined by the protocol specs except ban and invite
5730 lists. (Also, private channel key mode is supported but support for
5731 setting private channel key in client is missing, thus, this mode
5732 has no effect on client side (except that server requires that the
5733 client uses private channel key and normal channel traffic does not
5736 Also, invite mode works per se, but INVITE command does not work
5737 yet correctly, so you can set channel as invite only channel but
5738 inviting clients to the channel does not work (it is yet to be
5739 thought what's the best way to do it).
5741 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5742 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5743 Implemented CUMODE command to change user's mode on the channel.
5744 Supports all modes defined by the protocol specs.
5746 * Added NAMES command reply to return users modes on the channel.
5748 * Removed unnecessary and slow ciphers from lib/silccrypt.
5750 * Set SO_KEEPALIVE option to connection sockets by default.
5752 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5754 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5755 redefined the Notify Payload into protocol specs.
5757 * Added silc_id_payload_parse_id to get ID directly from raw
5760 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5762 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5763 accept searching by Client ID as well.
5765 * Added support for LEAVE and SIGNOFF notify types in client library.
5767 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5768 to parse ID Payload from raw data.
5770 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Added flags parameter into silc_ske_assemble_security_properties
5773 function in lib/silcske/silcske.[ch].
5775 * Changed notify client operation to fit better for notify messages
5776 sent by server. The notify payload received from server is now
5777 passed to the application (after parsing it to SilcNotifyPayload).
5778 It is application's responsibility to retrieve the arguments
5779 from the payload and show the message the way it wants. The message
5780 sent by server is implementation specific.
5782 * Changed public keys to comply with the protocol specification.
5783 Old public keys are not supported anymore and are not compatible.
5785 * Removed nickname from Channel Payload as the latest draft removed
5786 it. The client must resolve the nickname from the NAMES command
5787 reply received when it joined the channel.
5789 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5791 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed some errors in protocol specification drafts.
5795 * Created lib/silccore/silcnotify.c to implement Notify Payload
5796 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5797 generic payloads described by protocol specifications. The file
5798 includes implementations for ID Payload and Argument Payload.
5800 * Changed Command Payload implementation to use the new Argument
5801 Payload. Changed command_xxxx_payload to command_payload_xxxx
5802 to comply with SILC coding conventions.
5804 * Added suppport for Argument Payload handling in Notify Payload
5805 implementation as protocol requires it. Added the new support
5806 into server and client lib as well.
5808 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Added support for multiple nicknames on same channel. [n] is
5811 added locally to the nickname if there are more than one same
5812 nicknames on the channel.
5814 * Server now sends all nicknames that matched WHOIS request.
5815 Client also shows the list received from server.
5817 * Added TOPIC command to client side. User can now set and show
5818 current topic on channel.
5820 * Added MOTD command to client and server. Also, server sends the
5821 motd when client connects to the server.
5823 * Changed version strings to comply ISO 8601.
5825 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Fixed protocol error handling in client library. It should now
5828 cope even if the SKE fails for some reason.
5830 * Made new protocol specification drafts for submitting to IETF.
5832 * Implemented TOPIC command to server in silcd/command.c.
5834 * Added two new notify types into lib/silccore/silcnotify.h:
5835 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5836 notify nickname change and topic setting/change on a channel.
5838 * API change of command_reply operation in client library. The
5839 application gets now the status type received from server as well.
5841 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5845 * Cras fixed and optimized the packet handling even further and
5846 it should work now. Minor change to the prototype of function
5847 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5849 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added new function into lib/silcutil/silcschedule.[ch]:
5852 silc_schedule_with_fd to select() a specified fd. The function
5853 returns after timeout expires or data arrives or goes. The
5854 function is used by packet routines to wait that all data is
5855 received from network.
5857 * Fixed data reading from network in lib/silccore/silcpacket.c.
5858 The code now assures that all data is read from the fd and then
5859 continues packet processing. This was a bug fix since the code
5860 used to drop some data in some circumstances.
5862 * Added new function into lib/silcclient/client.[ch]:
5863 silc_client_start_key_exchange to start key exchange after
5864 connection has been established to server. The code internally
5865 now uses this funtion but its main purpose was to provide it
5866 for applications that perform their own connecting. After
5867 application has created a connection it merely calls this
5868 function to start the key exchange between client and server.
5869 The library takes care of everything else after that.
5871 Updated also lib/silcclient/README to explain the usage of
5874 * Do not send to application information that connection has
5875 been established. Application gets notified it by connect
5878 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Applied cras's patch to add silc_schedule_one function. The
5881 function runs scheduler once and returns.
5883 * Fixed the scheduler after cras messed it up. The timeout
5884 handling works now as it's supposed to work.
5886 * Added into lib/silccore/ silcnotify.h to include notify
5887 message types support. Changed silc_server_send_notify*
5888 functions, in server.[ch], to support those new notify types.
5889 Added the support for the notify types into client library,
5890 as well. Added new notify client operation into ops.h in
5893 * Changed silc_server_packet_send_to_channel to send normal
5894 packets instead of just channel message packets. The function
5895 is now used to send the notify packets to channels. It is not
5896 used to send channel message packets anymore, as server never
5899 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5900 va_arg()s as it seems to require it nowadays. I guess, if SILC
5901 is compiled with older va_arg() the new code should work anyway.
5903 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Splitted core library. Core library (lib/silccore) includes
5906 now only SILC protocol specific core (and common) components.
5907 Created new utility library (lib/silcutil) that includes more
5908 generic purpose stuff. The stuff for util library was taken
5909 from the old core library. This was minor and easy split.
5911 * Created SILC Client Library (lib/silcclient) that includes
5912 implementation of the SILC client without user interface. This
5913 was major move from silc/ directory. The code has been changed
5914 so that it is transparent towards the user interface. The
5915 silc/ directory includes now the same user interface as before
5916 and it uses the new client library. Read lib/silcclient/README.
5917 Basicly, the client library performs everything else related
5918 to SILC except user interface handling. Also, configuration
5919 files are considered to be part of user interface and library
5920 does not handle them.
5922 This change also changed a lot of structures, function naming etc.
5923 Most important change was that SilcClientWindow object was
5924 renamed to SilcClientConnection in the client library. Created
5925 also new file lib/silcclient/ops.h. Also added new files
5926 silc/local_command.[ch] and silc/client_ops.[ch].
5928 All these changes were made to make it easier for user interface
5929 designers to create what ever user interface for the SILC client
5932 It is also expected that the server will be moved to lib
5933 directory as well and SILC Server Library will be created;
5934 sometimes in the future.
5936 * Removed Local commands from lib/silccore/silccommand.h as
5937 they are application specific and new client library does not
5938 handle any of those anymore.
5940 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5941 old client implementation in silc/.
5943 * Added support for callback functions in SILC_LOG_* macros.
5944 Application can now set its own callbacks that will be called
5945 instead of using the default functions that will always print
5946 the debug messages to stderr (or stdout). Also, debugging can
5947 now be disabled by setting silc_debug to FALSE and re-enabled by
5948 setting it to TRUE. Note, that logging will still work even
5949 if debugging is disabled.
5951 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5952 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5953 silc_log_reset_debug_callbacks.
5955 * To enable debugging in silc client one must give now -d
5956 option on command line.
5958 * Changed silc_schedule_init to automatically allocate task queues
5959 if they are not allocated before calling it.
5961 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Added GMP 3.1 into math library.
5965 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5968 a channel in SILC network. The packet is used by servers and
5969 routers to notify other routers that user has left a channel.
5970 This little feature was missing until now. Added the feature
5971 to protocol specification as well.
5973 Added functions: silc_server_send_remove_channel_user and
5974 silc_server_remove_channel_user into server.[ch].
5976 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5977 lib/silccore/silcpacket.h. However, they are not implemented
5980 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5982 * Fixed joining to a channel and sending channel messages
5983 between server and router. The channel message sending should
5984 now work inside a cell.
5986 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Fixed the private message sending between server and router.
5989 The private message sending should now work inside a cell.
5991 * Added silc_server_replace_id into server.[ch] to replace
5992 existing ID in the SILC network.
5994 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5995 and silc_idlist_replace_server_id into idlist.[ch] in server.
5997 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Fixed the server to server connections. Server can again now
6000 connect to router. Router to router connections probably does
6003 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Added dynamic protocol registering support. Now protocols can
6006 registered and unregistered on the fly. Patch by cras.
6008 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Added lib/contrib directory to hold routines that some platforms
6011 don't have but are needed by SILC.
6013 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6014 into lin/contrib to provide getopt() and getopt_long() for
6015 those who don't have it.
6017 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Added AWAY command to client. When away message is set and
6020 client receives a private message packet the client automatically
6021 replies to the sender with the away message.
6023 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6024 bug seemed to be the cause of recent problems when compiling
6027 * Added version detection support to SKE protocol specification
6028 and added the new changes to the SKE implementation as well.
6029 There were other minor changes in the SKE protocol as well.
6031 Many changes in lib/silcske/silcske.[ch] and in
6032 lib/silcske/payload.[ch].
6034 * Added ^U functionality, clear input line. Patch from cras.
6036 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Mainly small bugfixes on core library. Fixed some debugging
6039 logging and buffer overflow in silclog.c.
6041 * Updated config.sub and config.guess on the distribution tree.
6043 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Added command lagging support in server. Client may execute
6046 commands now only once in two seconds.
6048 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Optimized packet reception. MAC computation and checking is now
6051 also more optimized. A lot previously duplicated code is now
6052 used as generic by both client and server.
6054 * Fixed key pair generation in clientutil.c
6056 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added into lib/silccore/silcbufutil.[ch] new function;
6059 silc_buffer_realloc.
6061 * Moved generic packet sending/encryption functions to
6062 lib/silccore/silcpacket.[ch] from client and server. Some
6063 rewriting of the functions.
6065 * Moved all generic packet reception/decryption functions to
6066 lib/silccore/silcpacket.[ch] from client and server. The
6067 packet processing is now much cleaner in both client and server.
6068 These were major changes in both client and server.
6070 * Created many common functions in server to do packet sending.
6071 Previously code were duplicated a lot, this has been removed
6074 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Rewrote major parts of the ID cache system. Don't know
6077 whether it is better now or not but at least the API is more
6080 * Major rewrite on ID cache stuff on client because of the ID
6081 cache API changes. Added idlist.c to client.
6083 * Also major rewrite on ID cache stuff on server as well.
6084 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6085 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6086 in hand, instead they are all put into the ID cache system now.
6087 All server_idlist_* routines uses ID cache now instead of
6088 traversing its own lists (those lists does not exist anymore).
6089 SilcIDList though still exists. Also, SilcXXXEntry's are
6092 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Finally made the SKE implementation compliant to the protocol
6095 specification. All mp integers are now binary encoded as
6096 opposed being HEX encoded.
6098 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6101 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6102 functions: silc_[encode/decode]_pem. Also added function
6103 silc_encode_pem_file to PEM encode with newlines ('\n') for
6106 * SILC public keys are now encoded either PEM or binary. Same
6107 option is for private keys as well. By default private keys
6108 are binary encoded and public keys PEM encoded. Silly HEX
6109 encoding were removed.
6111 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6112 function to create fingerprints.
6114 * Fixed a bug in SHA1; does not change the original data anymore.
6116 * Partly implemented INFO command on client and server side.
6117 Fixed CLEAR command. Changes to SERVER command; show current
6118 server(s) when giving command without arguments. Added
6119 VERSION command to client.
6121 * Added check to server that unregistered connections cannot
6122 execute commands (unless it is specificly allowed).
6124 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Fixed screen refresh.
6128 * Fixed channel joining bug from client. On some circumstances
6129 client tried to join to a channel it had already joined.
6131 * Added public key verification process into client's protocol.c.
6132 The client now verifies the public key from user and saves
6133 it into ~./silc/serverkeys/ directory.
6135 Added into: clientutil.[ch]: silc_client_verify_server_key.
6137 * Changed SKE protocol's silc_ske_initiator_finish function
6138 to accept callback function that verifies the received public
6139 key. Removed old silc_ske_verify_public_key function.
6141 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6143 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6144 silc_pkcs_private_key[_data]_set.
6146 * Made the password and public authentication more cleaner in
6147 server's protocol.c.
6149 * Removed historic and obsolete protocol `channel_auth' from
6150 both client and server.
6152 * Removed wrong way of sending command status messages from
6153 server to client in server's command.c. The old way violated
6154 protocol specification.
6156 Changes to silccore/silccommand.[ch]: removed
6157 silc_command_encode_status_payload -> not needed anymore,
6158 changed silc_command_encode_payload_va to accept extra
6159 argument on variable argument list. The argument type must
6160 now be provided to the function. Also, added new function:
6161 silc_command_encode_reply_payload_va which is same as
6162 normal command_encode_payload_va except command status type
6163 is provided as extra argument.
6165 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Added ~./silc directory handling. The directory includes the
6168 public and private keys for the client.
6170 Added silc_client_check_silc_dir, silc_client_create_identifier
6171 and silc_client_load_keys.
6173 * Implemented SILC protocol compliant public key. Added public
6174 and private key saving to and loading from files.
6176 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6177 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6178 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6179 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6180 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6182 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6183 silc_pkcs_load_[public/private]_key.
6185 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Added silc_server_get_route (route.[ch]) to get connection
6188 data for the fastest route for given ID.
6190 * Implemented INVITE command on client and server. The command
6191 were re-defined in the SILC Protocol Specification and the
6192 implementation now complies with the specification.
6194 * Implemented PING command on client and server.
6196 * Implemented NAMES command on client and server. The server side
6197 supports currently only normal server not router server yet.
6198 Some changes to NAMES definition in SILC protocol specification.
6200 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Implemented LEAVE command on client and server.
6204 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6205 again. This change was made to the protocol as well. Server
6206 should not violate the protocol specification anymore.
6208 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6211 was tested. SOCKS4 was not but should work anyway.
