1 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed JOIN command parsing not to crash. Affected file
4 lib/silcclient/command.c.
6 * Fied the NICK_CHANGE notify to add the new client entry
7 even it is resolved. This removes an <[unknown]> nick
8 thingy bug in the client. Affected file is
9 lib/silcclient/client_notify.c.
11 * Do not try to allocate 0 bytes (efence does not like it)
12 in lib/silccore/silccomand.c when encoding payload.
14 * Do not take IRCNICK as nickname in Irssi SILC client since
15 it is not possible to set nickname before hand connecting
16 the server (TODO has an entry about adding auto-nicking
19 * Changed the silc_server_command_pending to check whether
20 there already exists an pending entry with the specified
21 command, command identifier and pending callback. This is
22 to fix IDENTIFY and WHOIS related crashes that may register
23 multiple pending commands with same identifier. Affected
26 * Fixed the server to reconnect to the router even if it
27 was already reconnecting and EOF was received. This to
28 fix a possibility that the server wouldn't ever try to
29 auto-reconnect to the router. Affected file silcd/server.c.
31 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
33 * Fixed the server's password authentication to use the
34 length of the locally saved password, and not the one
35 sent in the packet. Affected file silcd/protocol.c.
37 * Fixed same password authentication problem in the
38 Authentication Payload handling routines in
39 lib/silccore/silcauth.c.
41 * Yet another password authentication problem fixed with
42 channel password handling in silcd/command.c.
44 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
46 * If first character of string in silc_parse_userfqdn is '@'
47 then do not parse it. Affected file is
48 lib/silcutil/silcutil.c.
50 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
52 * Fixed minor bug in IDENTIFY command reply sending, which
53 caused various weird problems during JOIN when it was
54 resolving names for users. Affected file silcd/command.c.
56 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
58 * Fixed the IDENTIFY command reply sending to chech better valid
59 clients. It was possible to send incomplete list of replies.
60 Affected file silcd/command.c.
62 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
64 * Added silc_client_command[s]_[un]register functions now to
65 dynamically register the commands in client library. Removed
66 the static table of commands. This allows the client library
67 to call commands without causing the application to know about
68 what commands library has called.
70 Removed the INFO command reply kludge to detect when the command
71 was called by library. Now library use its own command reply
72 function for INFO command.
74 Added function silc_client_command_call to call a command.
75 Application can use it to call command, not access the structure
78 Now all commands that are sent by the client library (not
79 explicitly sent by application) use own command reply functions.
81 Affected files around lib/silcclient/ and in
84 * Fixed the WHOIS command reply sending to chech better valid
85 clients. It was possible to send incomplete list of replies.
87 Fixed the WHOIS and IDENTIFY to send the request to router
88 if normal server did not do it and did not find any results.
90 Affected file silcd/command.c.
92 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
94 * Moved the internal data from SilcClient context into its
95 own file, not accesible to application. Affected files
96 lib/silcclient/client.h and lib/silcclient/client_internal.h,
97 and other files in client library.
99 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
101 * Added doc/examples installation target in Makefile.am.pre.
104 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
106 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
107 commands the found client entry will be removed from the
108 cache, after notifying application about the error. Affected
109 file lib/silcclient/command_reply.c.
111 * Changed the /MSG to check for exact nickname user gave, and
112 not let `nick' match `nick@host' if it is only one found. Now,
113 user must type the exact nickname (like nick@host2) even if
114 there are no more than one same nicks found. This is to avoid
115 a possibility of sending nickname to wrong nickname since
116 `nick' could match `nick@host'. Affected file is
117 irssi/src/core/silc-servers.c.
119 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
121 * Do not print "you are now server operator" or similar when
122 giving /away command. Affected files are
123 irssi/src/silc/core/client_ops.c, silc-servers.h.
125 * Made the silc_server_command_pending_error_check to send
126 the same command reply payload it received back to the
127 original sender of the command. This way all arguments
128 that was received by the server will be received by the
129 client too. Affected file silcd/command.c.
131 * Added the silc_idcache_add to return the created cache entry
132 to a pointer. Affected file lib/silccore/silcidcache.[ch].
134 * Add global clients to expire if they are not on any channel.
135 This is because normal server will never know if they signoff
136 if they are not on any channel. The cache expiry will take
137 case of these entries. This is done by normal servers only.
138 The affected files are silcd/command_reply.c,
139 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
141 * If server receives invalid ID notification for WHOIS or
142 IDENTIFY and the ID exists in the lists, it is removed.
143 Affected file silcd/command_reply.c.
145 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
146 in client then client entry that it matches is searched and
147 the nickname is printed on the screen for user. Affected
148 file irssi/src/silc/core/client_ops.c.
150 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
152 * Use cache entry expire time in the LIST command reply to
153 purge old entries from the cache after the LIST command
154 reply has been received. This way we don't have non-existent
155 entries in the cache for too long. Affected file is
156 silcd/command_reply.c.
158 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
160 * If we are normal server, and we've not resolved client info
161 in WHOIS or IDENTIFY from router, and it is global client,
162 we'll check whether it is on some channel. If it is not
163 then we cannot be sure about its validity and will resolve it
164 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
165 file silcd/command.c.
167 * Search channel by name (if possible) rather than by ID
168 in IDENTIFY command's command reply. Affected file is
169 silcd/command_reply.c.
171 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
173 * Distribute to the channel passphrase in CMODE_CHANGE notify.
174 Updated specs and implemented it. Affected file silcd/command.c,
175 silcd/packet_send.c and silcd/packet_receive.c.
177 * Implemented the <founder auth> payload handling in the JOIN
178 command. If provided all conditions for channel joining
179 except requirement to provide correct passphrase can be
180 overrided by the channel founder. Updated the protocol specs.
181 Affected file silcd/command.c.
183 Added support for founder auth in JOIN command in client
184 library. Fixed the parsing of the JOIN command now to support
185 all options as they should be. The affected file is
186 lib/silcclient/command.c.
188 * Optimized the WHOIS and IDENTIFY commands to send the request
189 to router only if it includes nicknames or other names. If
190 they include only IDs then check the local cache first before
191 routing. Affected file is silcd/command.c.
193 * Added channels topic announcements. Affected file is
194 silcd/packet_receive.c and silcd/server.c.
196 * Fixed the silc_server_send_notify_topic_set to really destine
197 the packet to channel. Affected file silcd/packet_send.c.
199 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
200 library. Affected file lib/silcclient/client_notify.c.
202 * Added UMODE announcements. Affected file silcd/server.c.
204 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
206 * Memory leak fixes in:
208 lib/silcutil/silcsockconn.c
209 lib/silcske/silcske.c
212 lib/silccrypt/silcpkcs.c
213 lib/silccore/silccommand.c
214 lib/silccore/silcidcache.c
219 * ROBOdoc documented the lib/silcske/groups.h file and a
220 bit changed the interface for better.
222 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
224 * Update the client entry context in the ID cache after
225 nick change. Affected file lib/silcclient/command.c.
226 Fixes the CUMODE command when regaining founder privileges,
227 and a little WHOIS problem.
229 * Fixed silc_net_gethostbyname to correctly call the
230 inet_ntop. Affected file lib/silcutil/silcnet.c.
232 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
234 * Added IPv6 support checking to the configure.in.pre, added
235 also --enable-ipv6 option to override the check. Affected
236 file configure.in.pre.
238 * The silc_thread_create now calls the start function
239 directly if threads support is not compiled in. Removes
240 ugly #ifdef's from generic code. Affected files are
241 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
243 * Added silc_net_gethostby[name/addr]_async to asynchronously
244 resolve. Affected files are lib/silcutil/silcnet.[ch].
246 * Added support for rendering IPv6 based server, client and
247 channel IDs. Affected file lib/silcutil/silcutil.c.
249 * Added support for creating IPv6 based server IDs. Affected
250 file is silcd/serverid.c.
252 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
254 * Added silc_net_gethostby[addr/name] into the
255 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
256 routines. Added silc_net_is_ip[4/6]. Affected file is
257 lib/silcutil/unix/silcunixnet.c. All routines that take
258 address as argument now supports both IPv4 and IPv6 addresses.
260 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
262 * Fixed LIST command reply sending in server. Affected file
265 * Server now sends the kicker's client ID in the KICK notify
266 to the kicked client. Affected file silcd/command.c.
268 * The client library now parses the kickers client ID and
269 UI displays it. Affected files lib/silcclient/client_notify.c
270 and irssi/src/silc/core/silc-channels.c, module-formats.c.
272 * Made all payload parsing function prototypes consistent.
273 They all take now const unsigned char * and uint32 pair as
274 the payload data instead of SilcBuffer. Changes all around
275 the source tree. Other unsigned char* -> const unsigned char*
276 changes around the tree as well.
278 * Optimized SFTP client and server packet sending not to
279 allocate new buffer for each packet but to recycle the
280 first allocated buffer. Affected files are
281 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
283 * Optimized the SFTP client to use SilcList instead of
284 SilcDList for requests, because it is faster. Affected file
285 is lib/silcsftp/sftp_client.c.
287 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
288 into lib/silccore/silcid.[ch].
290 Renamed silcpayload.[ch] into silcargument.[ch].
292 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
294 * If client entry is deleted with active key agreement
295 session, abort the session.
297 The silc_client_abort_key_agreement now calls the completion
298 callback with new SILC_KEY_AGREEMENT_ABORTED status.
300 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
303 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Don't use __restrict in older GCC's. Affected file is
306 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
308 * silc_net_localhost now attempts to reverse lookup the
309 IP/hostname. Affected file lib/silcutil/silcnet.c.
311 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
312 command. It can be used to gain founder privileges at
313 the same time when joining the channel.
315 Defined that the SILC_NOTIFY_TYPE_KICKED send the
316 kicker's client ID as well. Updated protocol specs.
318 Defined that the server must send SILC_COMMAND_IDENTIFY
319 command reply with error status to client who sent
320 private message with invalid client ID.
322 Updated the protocol specification.
324 * Added silc_server_send_command_reply to send any
325 command reply. Affected file silcd/packet_send.[ch].
327 * Added silc_id_payload_encode_data to encode ID payload
328 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
330 * The server now send IDENTIFY command reply with error
331 status if client ID in private message is invalid. Affected
332 file silcd/packet_receive.c.
334 * Save the server key file with server's IP address in
335 the filename instead of hostname. The affected file is
336 irssi/src/silc/core/client_ops.c.
338 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
340 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
343 * Added libtool support for compiling shared objects in
344 lib/silcsim. Affected file configure.in.pre and
345 lib/silcsim/Makefile.am. Original patch by cras.
347 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
349 * Pid file configuration, and server's config file fixes
350 patch by toma. Updated CREDITS file.
352 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
354 * Fixed silc_client_channel_message to not try to decrypt
355 the message twice if it resolved the destination client
356 information. This could cause of dropping one channel
357 message. Affected file lib/silcclient/client_channel.c.
359 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
361 * Added silc_client_run_one into lib/silcclient/silcapi.h and
362 lib/silcclient/client.c. This function is used when the SILC
363 Client is run under some other scheduler, or event loop or
364 main loop. On GUI applications, for example this may be
365 desired to used to run the client under the GUI application's
366 main loop. Typically the GUI application would register an
367 idle task that calls this function multiple times in a second
368 to quickly process the SILC specific data.
370 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
372 * Fixed silc_server_drop() for dropping the supplementary
373 groups as well, this could cause a security hole on some
376 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
378 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
381 * Write PID file after dropping privileges. Added -F option
382 to run server on foreground. A patch by debolaz.
383 Affected files silcd/server.c, silcd/silcd.c.
385 * Fixed MOTD to return the MOTD file server name. Affected
386 file silcd/command.c.
388 * Added INFO command reply handling to the Irssi SILC Client.
389 Affected file irssi/src/silc/core/client_ops.c.
391 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
393 * Fixed the silc_idcache_list_* routines to really support
394 the dynamic list. Fixes a crash. Affected file is
395 lib/silccore/silcidcache.c.
397 * Fixed the LIST command reply to really call LIST command's
398 pending callbacks. Affected file silcd/command_reply.c.
400 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Update conn->local_entry->nickname after giving NICK
403 command. Affected file lib/silcclient/command.c.
405 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
407 * Added the [pid] option to the silcd configuration file
409 Affected files: serverconfig.[ch] and silcd.c
411 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
413 * Save fingerprint in WHOIS command reply in server.
414 Affected file silcd/command_reply.c.
416 * Fixed NICK commands pending callback registration.
417 Affected file lib/silcclient/command.c.
419 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Use ++server->cmd_ident when sending commands in server,
422 instead of random number. Affected file silcd/command.c.
424 * Fixed GETKEY command reply to call actually GETKEY pending
425 command callbacks. Affected file silcd/command_reply.c.
427 * A bit stricter check for nicknames. Check for same nickname
428 in NICK command also. Affected file silcd/command.c.
430 * Do not call INFO command everytime client ID changes, only
431 during first connecting. Affected file lib/silcclient/client.c.
433 * Set the new nickname only after successful command reply for
434 NICK command is returned by server. Affected file
435 lib/silcclient/command.c.
437 * Remove nicknames from nicklist during server_signoff notify.
438 Should fix /NAMES bit more. The affected file is
439 irssi/src/silc/core/silc-channels.c.
441 * Added `fingerprint' field to the SilcIDListData in the
442 silcd/idlist.h to hold the fingerprint of the client's
445 Send the fingerprint of the client's public key in WHOIS
448 Affected files silcd/command.c, and silcd/idlist.[ch].
450 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
451 create fingerprint from given data.
453 * Show the fingerprint of the client's public key in WHOIS.
454 Affected files irssi/src/module-formats.[ch] and
455 irssi/src/silc/core/client_ops.c.
457 * Format the multiple same nicknames also during JOIN and
458 NICK_CHANGE notifys. Affected file is
459 lib/silcclient/client_notify.c.
461 * Do not print error on screen for invalid private message
462 payload since it can come if someone is sending private
463 messages with wrong key. Affected file
464 lib/silccore/silcprivate.c.
466 * Fixed multiple concurrent /PING crash. Affected file
467 lib/silcclient/command.c.
469 * Changed the wrong ID encoding. All IP addresses must be
470 in MSB first order in encoded format. They were encoded
471 wrong and was in LSB format. Affected files are
472 silcd/serverid.c, lib/silcutil/silcutil.c.
474 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
476 * Call the `connect' client operation through the scheduler
477 in case of error. Affected file lib/silcclient/client.c.
479 * Call the `failure' client operation even if the error
480 occurred locally during a protocol. Affected file is
481 lib/silcclient/protocol.c.
483 * Added support of sending LIST command to router from normal
484 server. This way normal server can get list of all channels
485 in the network too. Fixed the channel list sending in the
486 server too. Affected files are silcd/command.c, and
487 silcd/command_reply.[ch].
489 * Added silc_server_update_channels_by_server and
490 silc_server_remove_channels_by_server. They are used during
491 disconnection of primary router and in backup router protocol.
492 Affected file silcd/server_util.[ch], silcd/server.c and
493 silcd/server_backup.c.
495 * Fixed channel adding to global list in IDENTIFY command
496 reply in server. Affected file silcd/command_reply.c.
498 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
500 * If the incoming packet type is REKEY or REKEY_DONE process
501 that packet always synchronously. Fixes yet another MAC
502 failed error on slow (dialup) connections. Affected file
503 lib/silcclient/client.c and silcd/server.c.
505 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Call check_version SKE callback for initiator too. Affected
508 file lib/silcske/silcske.c.
510 * Implemented fix for security hole found in the SKE that was
511 fixed in the specification few days back; the initiator's
512 public key is now added to the HASH value computation.
513 Added backwards support for the old way of doing it too, for
514 old clients and old servers. Affected file is
515 lib/silcske/silcske.c.
517 * Enabled mutual authentication by default in SKE. If initiator
518 is not providing mutual authentication the responder will
519 force it. This will provide the proof of posession of the
520 private key for responder. The affected files are
521 lib/silcclient/protocol.c and silcd/protocol.c.
523 * Do not cache anymore the server's public key during SKE.
524 We do mutual authentication so the proof of posession of
525 private key is done, and if the server is authenticated in
526 conn auth protocol with public key we must have the public
527 key already. Affected file silcd/protocol.c.
529 * Added new global debug variable: silc_debug_hexdump. If
530 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
531 file lib/silcutil/silclog.[ch].
533 * Fixed compilation warning due to char * -> const char *.
534 Affected files lib/silcutil/silcnet.h, and
535 lib/silccore/silcauth.[ch].
537 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
539 * Fixed CMODE command when new channel key was created. If
540 the creation failed the old key was removed. Next time giving
541 same command would crash the server since the old key was
542 freed already. Affected file silcd/command.c.
544 * Fixed the silc_server_announce_get_channels to not crash
545 on reconnect. Affected file silcd/server.c.
547 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Added silc_log_set_debug_string function to set a regex
550 string to match for debug output. Only the function names,
551 or filenames matching the given debug string is actually
552 printed. This way it is possible to filter out those debug
553 strings that user is not interested in.
555 Fixed a bug in silc_string_regexify.
557 Affected files lib/silcutil/silclog.[ch], and
558 lib/silcutil/unix/silcunixutil.c.
560 * Changed the -d options in both server and Irssi SILC client
561 to take the debug string as argument. Affected files
562 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
564 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Added silc_hash_babbleprint to create a Bubble Babble
567 Encoded fingerprint. The encoding is developed by Antti

577 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Fixed a security problem found in SKE. The initiator's
580 public key too is now added to the HASH hash value creation
581 which is signed by the responder to create the SIGN value.
582 This will prevent anyone in the middle to lie to the responder
583 about the initiator's public key. If this is done now, the
584 man in the middle will get caught. Updated the protocol
587 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
589 * Better installation directory handling. Configure module
590 paths and other paths automatically to example_silc* files
591 in doc/. A patch by toma.
593 * Fixed compiler warning from MPI library, and from SILC RNG.
596 * Added SILC_SERVER_PID_FILE to define the pid file for server.

640 * Fixed the silc_client_packet_parse to not to increase
641 the packet sequence number if the conn->sock and the
642 current socket connection is not same. This can happen
643 for example during key agreement when the conn includes
644 multiple socket connections (listeners). Affected file
645 lib/silcclient/client.c.
647 * The sender of the file transfer request now provides also
648 the pointer (listener) for the key exchange protocol. If
649 the listener cannot be created then it sends empty key
650 agreement and lets the receiver provide the listener.
652 Added `local_ip' and `local_port' arguments to the
653 silc_client_file_send. If they are provided they are used,
654 if not then it will attempt to find local IP address, if
655 not found or bind fails then the remote client will provide
658 Affected files are lib/silcclient/client_ftp.c and
659 lib/silcclient/silcapi.h.

668 of the client's public key (if the proof of posession of the
669 corresponding private key is verified by the server).
670 Updated to the protocol specification.
672 * Added support of receiving the client's public key's
673 fingerprint in command reply in client library. Affected
674 file is lib/silcclient/command_reply.c, and

733 during SERVER_SIGNOFF, but invalidate it. This way we
734 preserve the WHOWAS info for the client. Affected file
737 * Fixed SERVER_SIGNOFF notify handling in the server. The
738 server is now able to process incoming SERVER_SIGNOFF notify
739 for a server that it doesn't even know about. It will remove
740 the clients provided in the notify. Affected file
741 silcd/packet_receive.c.
743 * Check for partial packet in data queue after every packet that
744 was found from the queue. Return and wait for more data if
745 there is partial data in queue. Affected file is

770 available. It is used in padding generation. Affected file
771 lib/silccrypt/silcrng.[ch].
773 * All packets in client library are now processed synchronously.
774 Optimized packet processing a lot. Affected file
775 lib/silcclient/client.c.
777 * All server connection packets are processing synchronously
778 now in server, to optimize packet processing. Affected file
781 * Include files are installed now only in Toolkit distribution
782 if make install is given. Affected files: all Makefile.am's.
784 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
786 * Assure that silc_client_notify_by_server_resolve does not
787 resolve the client information multiple times. If it cannot
788 be found by the first it cannot be found at all. Affected
789 file lib/silcclient/client_notify.c.
791 * Fixed WHOWAS command reply calling. Affected file
792 lib/silcclient/command_reply.c.
794 * Removed all references to silc_idlist_get_client from the
795 Irssi SILC client since that call is internal call used by
796 the library. The Irssi SILC client will use now client
797 retrieval functions found in silcapi.h.
799 * Fixed a bug in resolving nickname info before sending
800 private message. It used freed memory. Affected file
801 irssi/src/silc/core/silc-servers.c.
803 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

822 * Added silc_net_localip to return local host's IP address.
823 Affected file lib/silcutil/silcnet.[ch].
825 * If key exchange or rekey protocol is active for a connection
826 parse all packets syncronously since there might be packets
827 in packet queue that we are not able to process without first
828 processing packets before them. Affected file silcd/server,
829 lib/silcclient/client.c.
831 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
832 whether library should continue processing the packet.

916 * Redefined the SILC packet header to include the padding
917 length. Affected file lib/silccore/silcpacket.[ch].
919 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
920 length for maximum padding up to 128 bytes). Affected
921 file lib/silccore/silcpacket.h.
923 * Removed all backwards support for old 0.5.x MAC thingies.
924 The SILC packet header change makes it impossible to be
925 backwards compatible.
927 * Send the ENDING packet with timeout in the backup resuming
928 protocol. This is to assure that all routers has connected
929 to the primary router. Affected file silcd/server_backup.c.
931 * Changed the RNG to take the first IV from random data. It
932 used to take it from zero actually. Changed the RNG also
933 to use /dev/urandom during session. /dev/random is used
934 in initialization. Affected file lib/silccrypt/silcrng.[ch].
936 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

939 (the packet length) encrypted. Affected files aroung the
940 code tree, lib/silccore/silcpacket.[ch]. Removed the
941 SilcPacketCheckDecrypt callback. It is not needed anymore
942 since the silc_packet_receive_process will determine now
943 whether the packet is normal or special.
945 * Implemented the unidirectional MAC keys. Affected files
946 lib/silcske/silcske.c, silcd/protocol.c and
947 lib/silcclient/protocol.c.

954 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Allow backup router to announce servers. All servers
957 announced by backup router are added to the global list
958 automatically. Update hte server's socket to our primary
959 router also when backup router announces a server.
960 Affected file silcd/packet_receive.c.
962 * Do not update the client->router in the function
963 silc_server_udpate_clients_by_server if the client is on
964 global list. We might fail to find any specific server
965 for locally connected clients and local cell clients. They
966 should still use the `from' and not `to' as client->router.
967 This fixes backup router resuming protocol. Affected file
970 * Decrease channel statistics count only if the channel
971 deletion worked. Affected files are silcd/server.c and
974 * Added silc_server_update_servers_by_server to update origin
975 of all server entries. Used during backup router protocol.

989 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Made better checks that the channel message is not sent
992 to the router it came from. Affected file is
993 silcd/packet_send.c. Fixed memory leak too.

1011 Affected file silcd/packet_send.c.
1013 * Changed the SFTP Filesystem interface. Changed the
1014 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1015 the filesystem operation function. The SilcSFTPFilesystem
1016 is now a context that is allocated by all filesystem allocation
1017 functions and it already includes the operations structure
1018 and filesystem specific context. It is given as argument
1019 now to the silc_sftp_server_start. This made the interface
1020 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1021 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1023 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * Changed the backup router adding and getting interfaces
1026 in the server. The router that will be replaced by the
1027 specified backup router is now sent as argument. Affected
1028 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1031 * Added silc_net_addr2bin_ne to return the binary form of
1032 the IP address in network byte order. Affected files

1088 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1089 in the server to indicate disabled entry. All data read
1090 from the connection will be ignored and no data is sent
1091 for entry that is disabled. Affected files are
1092 silcd/idlist.h, silcd/server.c.
1094 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1113 * Moved lib/silccore/silcprotocol.[ch] to the
1114 lib/silcutil library.
1116 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1117 take variable argument list pointer as argument. Affected
1118 file lib/silcutil/silcbuffmt.[ch].
1120 * Added silc_buffer_set function that is used to set data
1121 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1122 Affected file lib/silcutil/silcbuffer.h.
1124 * Changed various routines in the core library to use the new
1125 silc_buffer_set instead of allocating new buffer only for
1128 * Added 64-bit value formatting and unformatting support to the
1129 silc_buffer_[un]format routines. Affected file is
1130 lib/silcutil/silcbuffmt.[ch].
1132 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1133 to includes/bitmove.h.
1135 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1137 * Fixed channel user mode saving in client library. Affected
1138 file lib/silcclient/command[_reply].c.
1140 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Defined the file transfer to the SILC Protocol. Added
1143 new packet type SILC_PACKET_FTP and defined File Transfer
1144 Payload. The mandatory file transfer protocol is SFTP
1145 (SSH File Transfer Protocol). Affected file in addition
1146 of the internet draft is lib/silccore/silcpacket.h.
1148 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1149 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1150 is used as part of backup router protocol when the primary
1151 router of the cell is back online and wishes to resume
1152 the position as primary router.
1154 * Redefined the MAC generation keys in the protocol. The
1155 same key is not used anymore in both direction. Both
1156 direction will now use different keys for sending and
1157 receiving. This fixes a potential security flaw. This
1158 change causes incompatibilities in the protocol.
1160 * Redefined also the MAC computation from the packet.
1161 An packet sequence number is now added to the MAC
1162 computation. This prevents possible replay attacks against
1163 the protocol. This change too causes incompatibilities
1166 Added `sequence' field to the SilcPacketContext to hold
1167 the current sequence number for the packet.
1169 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Added `created' field to the SilcIDListData in the file
1172 silcd/idlist.h to indicate the time when the entry was
1175 * Added `created' field to the SilcChannelEntry too. Affected
1176 file silcd/idlist.h.
1178 * Added `creation_time' aguments to all the announcement functions
1179 in the server. If it is provided then only the entries that
1180 was created after the provided time frame are actually
1181 announced. Affected file silcd/server.[ch].
1183 * The protocol says that the Channel ID's IP address must be
1184 based on the router's IP address. Added check for this in
1185 the silc_server_new_channel when processing incoming New Channel
1186 Payload. Affected file silcd/packet_receive.c.
1188 * Print out the correct version with --version in SILC client.
1189 Affected file irssi/src/silc/core/silc-core.c.
1191 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1193 * Fixed WHOWAS command to check for completnes of the client
1194 entry always, not just when the command is coming from client.
1195 Affected file silcd/command.c.
1197 * Added new function silc_server_packet_queue_purge to purge the
1198 outgoing data queue to the network. After the function returns
1199 it is guaranteed that the outgoing packet queue is empty.
1200 Affected file silcd/packet_send.[ch].
1202 * Purge the outgoing packet queue in the rekey protocol's final
1203 callback to assure that all rekey packets go to the network
1204 before quitting the protocol. Affected file silcd/server.c.
1206 * Added silc_client_packet_queue_parse as similar function as
1207 in server to the client library. The affected file is
1208 lib/silcclient/client.c.
1210 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Splitted silcd/server.c and created silcd/server_util.[ch]
1213 for utility functions.
1215 * Added new socket flag SILC_SF_DISABLED to indicate that the
1216 connection is open but nothing can be sent to or received from
1217 the connection. Affected file lib/silcutil/silsockconn.[ch].
1218 The checking for disabled socket is checked in the low level
1219 silc_socket_write and silc_socket_read functions.
1221 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * Allow only nicknames and channel names that fits into the
1224 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1226 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * When processing JOIN command reply in server check that if
1229 the channel exists in our global list we'll move it the local
1230 list. Affected file silcd/command_reply.c.
1232 * Fixed the check whether client is joined on the channel already
1233 in JOIN command. Affected file lib/silcclient/command.c.
1235 * Fixed the JOIN command reply to check whether the channel
1236 already exists. Affected file lib/silcclient/command_reply.c.
1238 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Added silc_ske_status_string to map the SKE error numbers
1241 to readable strings. The affected files are
1242 lib/silcske/silcske[_status].[ch].
1244 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Do not show the private channels on the WHOIS channel list
1247 as it is not allowed by the protocol. The affected file is
1250 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Assure that the packet length digged from the actual packet
1253 is something sensible in the silc_packet_decrypt_rest_special
1254 in lib/silccrypt/silcpacket.c.
1256 * Free and NULL the allocated pointer in silc_hmac_alloc if
1257 the HMAC allocation fails. The affected file is
1258 lib/silccrypt/silchmac.c.
1260 * Print the selected security properties to the log files in
1261 the server. Affected file silcd/protocol.c.
1263 * Add SKE's reference counter even if calling the completion
1264 callback manually. Otherwise it goes negative, although it
1265 does not cause any problems. The affected file is
1266 lib/silcske/silcske.c.
1268 * Remove the client entry with short timeout after giving the
1269 KILL command. Affected file lib/silcclient/command.c.
1271 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1272 case all found clients are already disconnected (WHOWAS would
1273 found them) in the server. Affected file silcd/command.c.
1275 * Update the last_receive (time of last data received) to be
1276 updated only when received private or channel message so that
1277 the idle time showed in WHOIS makes more sense.
1279 * Added boolean field `valid' in to the SilcClientEntry in the
1280 client library to indicate whether the entry is valid or not.
1281 This fixes the nickname change bug on channel when changing
1282 the nickname to be same than the old (like nick to Nick) the
1283 nickname formatter doesn't set the new nick anymore to Nick@host.
1284 Affected file lib/silcclient/idlist.[ch].
1286 * Now actually fixed the nickname changing on disconnection.
1287 Added new function silc_change_nick to the Irssi SILC Client.
1288 Affected file irssi/src/silc/core/client_ops.c,
1289 irssi/src/silc/core/silc-nicklist.[ch].
1291 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Check that the public key exists in the GETKEY command before
1294 trying to encode it. Affected file silcd/command.c.
1296 * Print some notifications on received public keys with GETKEY
1297 command in the Irssi SILC Client. Affected files are
1298 irssi/src/fe-common/silc/module-formats.[ch],
1299 irssi/src/silc/core/client_ops.c.
1301 * Use IDENTIFY command to resolve the server information in the
1302 GETKEY command instead of INFO command. Affected file
1303 lib/silcclient/command.c.
1305 * All command reply functions in the client library now calls
1306 the pending command reply callbacks even if an error has
1307 occurred. The server has done this a long time and now it was
1308 time to move the client library to this as well. Now all
1309 errors can be delivered back to the pending command reply
1310 callbacks if necessary. Affected files are
1311 lib/silcclient/command[_reply].[ch].
1313 * Change the nickname on disconnection back to the username
1314 because in reconnect the server will enforce it to it anyway.
1315 Affected file irssi/src/silc/core/silc-servers.c.
1317 * Fixed a config file parsing bug in the Irssi SILC client.
1318 Affected file irssi/src/silc/core/clientconfig.c.
1320 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * When printing the channel mode on JOIN, verify that the
1323 channel key and channel's HMAC are valid. Affected file
1324 irssi/src/silc/core/client_ops.c.
1326 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1329 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1330 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1332 * Removed channel key rekey task deleting from the function
1333 silc_server_save_channel_key. Affected file silcd/server.c.
1334 Added explicit timeout task context instead that is used to
1335 delete the task if we are registering a new task before the
1336 new task has elapsed.
1338 * When channel key rekey occurs the client library now saves
1339 the old channel key for a short period of time (10 seconds) and
1340 is able to use it in case some is still sending channel
1341 messages encrypted with the old key after the rekey. Affected
1342 file lib/silcclient/[idlist.h|client_channel.c].
1344 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Added check to the silc_server_new_id_real to not accept
1347 new ID if it is the sender's own ID. Affected file is
1348 silcd/packet_receive.c.
1350 * Assure that we do not announce ourself or the one we've
1351 sending our announcements when we're router and are announcing
1352 servers to our primary router. Affected file silcd/server.c.
1354 * Fixed silc_server_command_identify_check_client to assemble
1355 correct WHOIS packet. It send corrupted WHOIS packet and
1356 caused problem with router to router connections. Affected
1357 file silcd/command.c.
1359 Fixed also silc_server_command_whois_check the same way
1360 as for the IDENTIFY command.
1362 * Added new SilcIDListStatus to the server in the SilcIDListData
1363 structure. The status now includes the current status of
1364 the entry (like registered, resolved etc.). Affected file
1365 silcd/idlist.[ch]. Defined a bunch of different status types
1366 as well. This replaced the old boolean registered field as well.
1368 Added resolve_cmd_ident field to the SilcClientEntry structure
1369 too so that if the entry is for example being resolved so
1370 another command may attach to the same pending command reply
1371 without requiring to resolve the same entry again. This concept
1372 should optimize the WHOIS and the IDENTIFY resolving under
1373 heavy load by taking away unnecessary resolving for entries
1374 that are being resolved already.
1376 Added support for adding multiple pending commands for one
1377 command idenfier. Affected file silcd/command[_reply].[ch].
1379 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1380 before deleting the data. Otherwise the hash table will have
1381 freed data in comparison functions. Affected file is
1382 silcd/command_reply.c.
1384 * Fixed silc_idlist_replace_client_id to add the new entry to
1385 the cache with NULL nickname. Otherwise there will be invalid
1386 memory as the nickname after the nickname is freed. Affected
1387 file silcd/packet_receive.c.
1389 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1390 saved into wrong slots because the previous number of entries
1391 was not taken into account. Affected file silcd/idlist.c.
1392 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1394 * If we are router and we receive JOIN notify to a channel that
1395 does not have any users then notified client is marked as the
1396 channel founder, as it is it. The affected file is
1397 silcd/packet_receive.c
1399 * Added to the extended hash table API's table_del_*ext functions
1400 the destructor as argument too, so that the caller can decide
1401 which destructor to use or whether to use destructor at all.
1402 Affected file lib/silcutil/silchashtable.[ch].
1404 * Fixed ID Cache purging. It actually deleted the entries from
1405 the hash table after the data was freed. The hash table ended
1406 up comparing freed memory. The affected file is
1407 lib/silccore/silcidcache.c.
1409 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Fixed Irssi SILC client's KILL command's HELP syntax.
1413 * The USERS command now resolves the detailed user information
1414 if the userinfo field is missing. Affected file is
1415 lib/silcclient/command_reply.c.
1417 * Do not print error in silc_file_read if the read file does
1418 not exist. Just silently return NULL. Affected file is
1419 lib/silcutil/silcutil.c.
1421 * Fixed the silc_log_output to not wine about NULL filename
1422 and to not create some bogus " " filename. Affected file is
1423 lib/silcutil/silclog.c.
1425 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Fixed various printing bugs on the user interface in the
1428 Irssi SILC Client. Minor changes that were forgotten from
1431 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Fixed the configure.in.pre and the compilation and distribution
1434 environment to support the new autoconf 2.52. That version is
1435 now required to compile the CVS trunk.
1437 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1440 to generally parse user@fqdn format strings. Affected file
1441 lib/silcutil/silcutil.c.
1443 * Added nickname_format and nickname_force_format fields to the
1444 SilcClientParams structure. The first one defines the format
1445 for the nicknames that the library will enforce if the receives
1446 multiple same nicknames. The second one is boolean value and
1447 can be used to force the library to always enforce the format
1448 to the nicknames regardles whether there are multiple nicknames
1449 or not. This configurable formatting was employed to flexibly
1450 support accessing multiple nicknames from the user interface.
1451 The userinterface can now set the nicknames to what ever format
1452 they prefer. Affected file lib/silcclient/silcapi.h.
1454 Added function silc_client_nickname_format to the file
1455 lib/silcclient/idlist.c. It performs the nickname formatting.
1457 Added new field `hostname´ to the SilcClientEntry context.
1458 It holds the hostname of the client. Affected file is
1459 lib/silcclient/idlist.h.
1461 * Irssi SILC Client sets the nicknames in nick@hostn format.
1462 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1463 irssi/src/silc/core/silc-core.c.
1465 The WHOIS printing now also shows both the real nickname and
1466 the formatted nickname so that user knows how to access the
1467 user if there are multiple same nicknames cached. Affected
1468 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1469 printing formatting too to take the hostname now as a separate
1470 argument. The Affected file is
1471 irssi/src/fe-common/silc/modules-formats.[ch].
1473 * Changed the silc_client_get_clients_local to accept the formatted
1474 nickname as argument. It accepts the real nickname too but the
1475 formatted nickname can be used to find the true entry from
1476 multiple entries. Affected file lib/silcclient/silcapi.h and
1477 lib/silcclient/idlist.c.
1479 * Added nickname_format_parse field to the SilcClientParams.
1480 It is a callback function provided by the application to parse
1481 the nickname out of the formatted nickname string. The library
1482 calls it to get the nickname from the formatted string. Since
1483 the application generally knows better the format of the nickname
1484 string it parses it instead of the library, even though library
1485 encodes the formatted string. If the callback function is not
1486 provided then the library will use the string as is. The
1487 affected file is lib/silcclient/silcapi.h.
1489 * All the nickname strings passed to the client library in
1490 commands are now expected to be formatted nickname strings.
1491 If the command does not support the formatted nickname string
1492 it will assume that the sent string is the actual nickname.
1493 Affected file lib/silcclient/command.c.
1495 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Added public key authentication support to OPER and SILCOPER
1498 commands in the client library. Affected file is
1499 lib/silcclient/command.c.
1501 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Changed the get_auth_methdod client operation to be asynchronous.
1504 It can be async if the application resolves the authentication
1505 method from the server during the negotiation. Added new
1506 SilcGetAuthMeth completion callback that the application will
1507 call after resolving the authentication method.
1509 Added function silc_client_request_authentication_method that
1510 the application can use to resolve the authentication method
1511 from the server. Added also SilcConnectionAuthRequest callback
1512 that the library will call after the server has replied. The
1513 application can call this function if it does not know the
1514 current authentication method.
1516 Affected files are lib/silcclient/client.c and
1517 lib/silcclient/silcapi.h.
1519 * The Irssi SILC client now automatically resolves the authentication
1520 method incase any configuration information is not present (and
1521 currently there never is). The affected file is
1522 irssi/src/silc/core/client_ops.c.
1524 * Fixed public key authentication from the client library.
1525 Affected file lib/silcclient/protocol.c. Changed also the
1526 protocol specification about the public key authentication in
1527 the connection authentication protocol. The actual data to be
1528 signed is now computed with a hash function before signing.
1530 * Fixed the public key authentication from the server as well.
1531 Affected file silcd/protocol.c.
1533 * Removed the mlock()'s from the memory allocation routines.
1534 Affected file lib/silcutil/silcmemory.c. The ./configure does
1535 not check anymore for the mlock(). Affected file is
1538 * Fixed USERS command in server to allow the execution of the
1539 command for private and secret channels if the client sending
1540 the command is on the channel. Affected file silcd/command.c.
1542 * Fixed silc_client_get_clients_local to return the clients
1543 count correctly. It could return wrong value. Affected file
1544 lib/silcclient/idlist.c.
1546 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1549 types. The assembler optimizations seemed not to like 64-bit
1550 data types. The assmebler optimizations thus are now enabled
1551 also for BSD systems as opposed to only enable them for Linux.
1553 * Do not check for threads at all on BSD systems. Affected
1554 file configure.in.pre.
1556 * Removed -n and -h options from the Irssi SILC Client since
1557 they are not used in silc.
1559 * Fixed the prime generation to assure that the first digit
1560 of the generated random number is not zero since our conversion
1561 routines does not like number strings that starts with zero
1562 digit. If zero digit is seen the random number is regenerated.
1563 This caused some corrupted RSA keys when the zero first digit
1564 was met. Affected file lib/silcmath/silcprimegen.c.
1566 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Fixed WIN32 configuration in the ./configure script.
1569 Fixed to include xti.h on environments that has it.
1570 Patches by Carsten Ilchmann and andrew.
1572 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Changed the silc_id_create_client_id to be collision
1575 resistant. It is now assured that there cannot be created
1576 two same client ID's. I suspect that some weird bugs in
1577 the server were actually caused by duplicate Client IDs.
1578 Affected file silcd/serverid.[ch]. A router receiving
1579 new ID now also assures and informs the sending server
1580 if the ID caused collision.
1582 * Changed the silc_id_create_channel_id to also assure that
1583 there are no collisions.
1585 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Statement about ignoring the Mutual Authentication flag when
1588 performing rekey with PFS was a bit misleading. It is ignored
1589 if it was set in the initial negotiation, it cannot be even
1590 set in the rekey. Fixed in the ke-auth draft. Started the
1591 new versions of the protocol drafts in the doc/.
1593 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Fixed a bug in silc_client_command_identify_save when saving
1596 new channel information. The channel name was no duplicated
1597 and caused crash on exit. Affected file is
1598 lib/silcclient/command_reply.c.
1600 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Fixed the getkey command handling in the server. Send just
1603 empty OK reply to the sender if the key could not be fetched
1604 (but everything else was ok, like the key just was not available).
1605 Changed the public key parameter to optional in the protocol
1606 specs so that empty OK reply can be sent. Affected file
1609 Added a message to Irssi SILC client to tell to user if the
1610 server did not return a public key.
1612 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1614 * Fixed a channel key regeneration bug. It registered new
1615 timeout tasks exponentially until all system resources were
1616 used. Affected file silcd/server.c.
1618 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Added the SILC Document generator to the scripts/silcdoc.
1621 It can be used to generate the Toolkit Reference Manual out
1622 of the source tree. Internally it will also use the RoboDoc
1623 generator now imported in util/robodoc.
1625 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Added couple of return's in rekey protocol if error orccurred
1628 during the protocol. The execution must be terminated.
1629 Affected file silcd/protocol.c. Also, terminate the protocol
1630 always with timeout.
1632 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * The client's Client ID was created initally from the wrong
1635 nickname (it could have been in format nick@host) in the
1636 silc_server_new_client. Affected file silcd/packet_receive.c
1638 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Added some SILC_LOG_ERROR's to various error conditions
1641 if client could not be added to ID cache. Affected files
1642 silcd/packet_receive.c and silcd/server.c.
1644 * When client's sock->user_data is freed, NULL also the
1645 client->router and client->connection pointers. Added check
1646 for these pointers being NULL to various places around the
1647 code. Affected file silcd/server.c.
1649 * Added client->data.registered == TRUE checks to various
1650 places around the code to assure that unregistered client's
1651 are not handled when it is not allowed. Affected file
1654 * Added `bool registered' fields to all
1655 silc_idlist_[server|client]_get_* routines to indicate whether
1656 the fetched client needs to be registered or not. Affected
1657 file silcd/idlist.[ch].
1659 * Add your own entry as registered to the ID cache in the
1660 server. Affected file server.c.
1662 * Fixed a bug in silc_server_new_server. The SilcServer was
1663 set as the new server's context instead of SilcServerEntry.
1664 This naturally caused some weird bugs.
1666 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Do not delete the channel rekey task when adding it
1669 for in silc_server_create_channel_key.
1671 * Changed the silc_server_create_channel_key to return
1672 TRUE or FALSE to indicate the success of the channel key
1675 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Fixed MSVC++ project files and added missing files to

1683 does not have it defined. Affected files are
1684 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1686 * Fixed buffer overflow from Irssi SILC Client. Affected
1687 file irssi/src/fe-common/core/themes.c.
1689 * Fixed double free in client library in the file
1690 lib/silcclient/client.c when disconnecting from server.
1692 * Applied double free patch from cras to Irssi SILC client.
1693 Affected files irssi/src/core/[modules/expandos].c
1695 * Fixed the disconnection handling to Irssi SILC Client.
1696 The application must call silc_client_close_connection
1697 in ops->connect client operation in case of failure of
1698 the connection. Affected file is
1699 irssi/src/silc/core/client_ops.c.
1701 * Do not set sock->protocol to NULL in the function
1702 silc_client_close_connection after executing the protocol's
1703 final callback since the sock might not be valid anymore.
1704 Affected file lib/silcclient/client.c.
1706 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Do not enable SILC_THREADS if the linking with libpthread
1709 did not happen. Affected file configure.in.pre.
1711 * Added notion to protocol specification that server must
1712 verify the sent authentication payload with CMODE when
1713 setting the channel founder key. Implemented it to the
1714 server. Affected file silcd/command.c.
1716 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Added _EXTRA_DIST SILC distribution variable to the
1719 distributions file. It is used to conditionally add extra
1720 files or directories to the specific distribution. Affected
1721 files ./prepare, Makefile.am.pre and distributions.
1723 Removed the `_' from the start of the distribution names.
1726 * Added README.WIN32 for instructions to compile the Toolkit
1729 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Fixed a double free in disconnection in the server. Affected
1732 file is silcd/server.c.
1734 * Fixed the lib/silcske/groups.c to work now also with GMP
1735 MP library. The string conversion did not work when using
1736 specific base and the base is indicated in the string as well.
1738 * Created win32/ directory which now includes MSVC++ specific
1739 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1740 It will appear only in the toolkit distribution
1742 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Changed the key material distribution function in case when
1745 the hash output is too short. The data is now concatenated
1746 a bit differently than it used to. Made the change to the
1747 SKE protocol specification.
1749 * Added better GMP detection to configure.in.pre. A patch
1752 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1754 * Fixed a minor bug in SKE that might cause some problem on
1755 some platforms. Affected file lib/silcske/silcske.c.
1757 * Added the cookie checking for initiator in the SKE. It checks
1758 that the responder returns the sent cookie unmodified. The
1759 affected file is lib/silcske/silcske.c. Added new SKE
1760 error type INVALID_COOKIE that can be sent during the
1761 negotiation. Fixed some memory leaks as well.
1763 * Added the "invalid cookie" error message to Irssi SILC client's
1766 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Added `task_max' field to the SilcClientParams to indicate
1769 the maximum tasks the scheduler can handle. If set to zero,
1770 default values are used. Affected file lib/silcclient/silcapi.h.
1772 * Fixed memory leaks in silc_client_close_connection. Affected
1773 file lib/silcclient/client.c.
1775 * Added silc_client_del_client_entry to client library to free
1776 all memory of given client entry. Affected file is
1777 lib/silcclient/idlist.[ch].
1779 * Added new functions silc_client_del_channel and
1780 silc_client_del_server to delete channel and server entries.
1781 Affected file lib/silcclient/[silcapi.h/idlist.c].
1783 * Removed silc_client_del_client_by_id from silcapi.h.
1785 * Fixed the INFO command to return the server's own info
1786 correctly when querying by Server ID. Affected file is
1789 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Removed the non-blocking settings in WIN32 code in the
1792 silc_sock_[read/write] and added SleepEx instead. Affected
1793 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1794 of input data is now checked with FIONREAD and ioctlsocket.
1796 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Call silc_schedule_task_del_by_context in the
1799 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1800 Affected file lib/silccore/silcprotocol.c.
1802 * Call silc_protocol_cancel for active protocols in the
1803 silc_server_close_connection if the funtion
1804 silc_server_free_sock_user_data has not been called.
1805 Affected file silcd/server.c.
1807 * Generic tasks cannot be deleted using the del_by_fd
1808 task deleting function since generic tasks does not match
1809 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1811 * Added a notion to SILCOPER help file that the SILCOPER works
1812 only on router server, not on normal server.
1814 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Added for WIN32 support for the new scheduler as well.
1817 Affected file lib/silcutil/win32/silcwin32schedule.c.
1819 * Fixed the SHA1 implementation to work on various platforms.
1821 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1824 API. It is part of the scheduler now. Everything else is
1825 as previously but some functions has changed their names.
1826 Checkout the lib/silcutil/silcschedule.h for the interface.
1827 Updated all applications to use the new interface. Affected
1828 files are lib/silcutil/silcschedule.[ch].
1830 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Found a bug in the SKE implementation. The HASH value,
1833 specified by the protocol, was not computed correctly. The
1834 public key of the responder was not added to the computation
1835 even though it is mandatory. Affected file lib/silcske/silcske.c.
1836 This unfortunately causes incompatibilities with older
1837 clients and servers.
1839 * Added WIN32 specific network init and uninit functions:
1840 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1841 the Winsock2. Affected file lib/silcutil/silcnet.h and
1842 lib/silcutil/win32/silcwin32net.c.
1844 * Set the socket always to nonblocking mode on WIN32 after
1845 reading data or writing data. Affected file is
1846 lib/silcutil/win32/silcwin32sockconn.c.
1848 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Fixed various compilation problems under WIN32. Affected
1851 files lib/silcutil/win32/silcwin32thread.c and
1852 lib/silcutil/win32/silcwin32schedule.c.
1854 * Removed all _internal.h #includes from public header
1855 files. Internal headers must never be included from
1858 Removed also the lib/silcske/payload_internal.h file.
1860 * All include files that may be needed (public and some others
1861 included by the public headers) by application developers are
1862 now copied to the ./includes directory. It does not copy any
1863 internal headers. Affected file Makefile.defines.pre and all
1864 Makefile.am's under lib/ and subdirs.
1866 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Do not change the ~/.silc directory's permissions automatically.
1869 Affected file irssi/src/silc/core/clientutil.c.
1871 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Do not cancel the protocol in silc_server_close_connection
1874 it might cause recursion. Now cancelled in the function
1875 silc_server_free_sock_user_data. Affected file silcd/server.c.
1877 * Fixed the silc_server_remove_clients_by_server to regenerate
1878 the channel keys correctly finally. Added also new function
1879 silc_server_remove_clients_channels to actually do it.
1880 Affected file silcd/server.c.
1882 * Fixed the silc_server_new_channel to not crash by giving
1883 wrong router to the new channel. Affected file is
1884 silcd/packet_receive.c.
1886 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1889 which is given as argument to the silc_client_alloc now.
1890 It can be used to configure the client and set various parameters
1891 that affect the function of the client.
1893 * The USERS command in server did not check whether the channel
1894 is private or secret. Affected file silcd/command.c.
1896 * Added new argument to the USERS command in protocol specification.
1897 The USERS command now can take the channel name as argument
1898 as well. Added support for this in client and server and
1899 updated the protocol specs.
1901 * Completed the GETKEY command in client. It can be now used
1902 to fetch also servers public key not only some clients.
1903 Affected files lib/silcclient/command[_reply].c.
1905 * Added silc_client_get_server to return server entry by the
1906 server name. Affected files lib/silcclient/silcapi.h and
1909 * Redefined the IDENTIFY command in protocol specification to be
1910 more generic. It now can be used to query information about
1911 any entity in the SILC Network, including clients, servers and
1912 channels. The query may be based either the entity's name
1913 or the ID. Added support for this in both client and server.
1915 Affected files silcd/command.c and lib/silcclient/command.c
1916 and command_reply.c.
1918 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1919 the _from_client and _from_server functions. Affected file
1922 * Added silc_client_get_channel_by_id_resolve to the file
1923 lib/silcclient/silcapi.h to resolve channel information by
1924 its ID. Added also silc_client_get_channel_by_id that
1925 does not resolve it from the server.
1927 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Added SilcServerEntry context into the client library
1930 to represent one server. The INFO command now allocates
1931 these to save the resolved server info. For now on the
1932 client library will also keep information about servers,
1933 connected and resolved with INFO.
1935 The INFO command now allocates the SilcServerEntry context
1936 and saves the server info there. The COMMAND_REPLY in
1937 the INFO now returns the parameters to application in
1938 same order as defined in the protocol specification.
1940 The entries are cached in the client->server_cache.
1942 * The INFO command is now issued after received the Client ID
1943 from the server. Affected file lib/silcclient/client.c.
1945 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1946 to the application as the mode changer might be server.
1947 It is guaranteed that NULL is not returned anymore to the
1948 application. Affected file lib/silcclient/client_notify.c.
1950 The ID Type is now also passed to the application so that
1951 it can check whether the returned entry is SilcClientEntry
1954 Added new function silc_client_get_server_by_id to return
1955 the server entry by ID. Affected files are the
1956 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1958 * Do not create the channel in the Irssi SILC Client when issuing
1959 the JOIN command but when received the sucessful JOIN command
1960 reply. Otherwise the channel might get created even though we
1961 could not join it. The Affected file is
1962 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1964 * Fixed a channel joining bug in router. The router must also
1965 check the channel modes, invite and ban lists etc. when serving
1966 the JOIN command sent by normal server. Affected file is
1967 silcd/command.c. The router now resolves the client's
1968 information from the server who sent the JOIN command if it
1969 does not know it, and processes the JOIN command only after
1972 * Changed the SilcCommandCb to take new argument; void *context2.
1973 Affected file lib/silccore/silccommand.h
1975 The second argument in the command callbacks in the server now
1976 includes the SilcServerCommandReplyContext if the command was
1977 called as pending command callback from the command reply.
1978 Otherwise it is NULL. When called as pending the status of the
1979 command reply will be checked and if it was erronous the
1980 error will be sent to the original sender of the command.
1981 This way the client always receives the error messages even
1982 though the server was actually the one who received the error
1983 when it resent the command to router, for example. Affected
1984 files silcd/command[_reply].[ch].
1986 * Fixed sending WHOWAS command's error message to client if
1987 the requested client could not be found. It was missing.
1990 * Changed the CMODE and CUMODE commands reply arguments in the
1991 protocol specification. The Channel ID is now sent in both
1992 of the commands to identify the channel. Implemented this
1993 new feature to the client and server. Affected files
1994 lib/silcclient/command_reply.c and silcd/command.c.
1996 * Made better checks for invite and ban lists in the JOIN
1997 command in server. Affected file silcd/command.c.
1999 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * The server now performs the incoming host IP/DNS lookup
2002 using the silc_socket_host_lookup and thus does not block
2003 the server anymore. Affected file silcd/server.c.
2005 * Completed the multi-thread support for SILC Scheduler in
2006 the lib/silcutil/silcschedule.c.
2008 * Fixed the configure.in.pre to detect the pthread correctly
2011 * Fixed a deadlock in silc_task_queue_wakeup in the file
2012 lib/silcutil/silctask.c.
2014 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Added new function silc_schedule_wakeup that is used in
2017 multi-threaded environment to wakeup the main thread's
2018 schduler. It needs to be used when a thread adds a new task
2019 or removes a task from task queues. After waking up, the
2020 scheduler will detect the task queue changes. If threads
2021 support is not compiled in this function has no effect.
2022 Implemented the wakeup mechanism to both Unix and WIN32
2023 systems. Affected files are lib/silcutil/silcschedule.[ch],
2024 lib/silcutil/unix/silcunixschedule.c and the
2025 lib/silcutil/win32/silcwin32schedule.c.
2027 * Added new function silc_task_queue_wakeup to wakeup the
2028 scheduler by the specified task queue. Affected file
2029 lib/silcutil/silctask.[ch].
2031 * The silc_socket_host_lookup_start now wakes up the scheduler
2032 after adding the timeout task. Affected file is
2033 lib/silcutil/silcsockconn.c.
2035 * The silc_socket_host_lookup is synchronous now if the threads
2036 support is not compiled in. However, the callback is still
2037 called asyncronously through the scheduler, anyway. Affected
2038 file lib/silcutil/silcsockconn.c.
2040 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Added new function silc_socket_host_lookup to perform
2043 asynchronous IP and FQDN lookups for the socket connection.
2044 Affected files lib/silcutil/silcsockconn.[ch].
2046 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2049 that may or may not compile the mutex support in.
2051 Changed the silc_mutex_alloc interface. It allocates the
2052 mutex now to the sent pointer and returns TRUE or FALSE.
2054 Affected file lib/silcutil/silcmutex.h.
2056 * Wrote the SILC Task Queue interface to support multi-threads.
2057 Affected file lib/silcutil/silctask.[ch].
2059 * Wrote the SILC Scheduler to support multi-threads. Affected
2060 file lib/silcutil/silcschedule.c.
2062 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2064 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2065 in lib/silcutil/win32/.
2067 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Defined SILC Mutex API and SILC Thread API and implemented
2070 them for Unix. Affected files are
2071 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2072 lib/silcutil/unix/silcunixmutex.c and
2073 lib/silcutil/unix/silcunixthread.c.
2075 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Fixed the silc_server_remove_clients_by_server's channel
2078 key re-generation. The hash table handling was incorrect
2079 and would not work with many channels. Affected file is
2082 * Fixed some memory leaks around the server code.
2084 * Rewrote the silc_server_get_users_on_channel to support IPv6
2085 based Client ID's. Affected file silcd/server.c.
2087 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2088 specification. However, a separate document must be written
2089 to define the detailed signing procedure and the payload
2090 associated with the flag. Defined the flag to the
2091 lib/silccore/silcchannel.h as well.
2093 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Changed the dynamic tables to static size tables in the
2096 lib/silccrypt/silchmac.c.
2098 * Removed GCC dependencies from the code. A patch by cras.
2100 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Do not show the error "Error receiving packet bla bla"
2103 in server if it really was not an error (-2 means that reading
2104 is pending). Affected file silcd/server.c.
2106 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Fixed a possible crash in silc_server_remove_clients_by_server
2109 in silcd/server.c. Fixed there also some memory leaks.
2111 * Fixed the silc_idlist_replace_client_id. It could replace
2112 wrong key in the hash table. Affected file silcd/idlist.c.
2114 * Do not check whether there are global users on the channel
2115 if the channel->global_users is FALSE. Affected functions
2116 silc_server_remove_from_one_channel and
2117 silc_server_remove_from_channels in silcd/server.c. Also,
2118 do not check if the removed client is local as we can be
2119 sure that global client was not removed from the channel
2120 and checking for global users is not needed.
2122 * The silc_server_remove_clients_by_server now re-generates
2123 the channel keys correctly for those channels that had
2124 clients removed from them. Affected file silcd/server.c.
2126 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Found the reason of random crashes in the server. We weren't
2129 ignoring the SIGPIPE signal (which can be sent in write())
2130 and it crashed the server. Affected file silcd/silcd.c.
2132 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Assure that sock->user_data is not NULL in the function
2135 silc_server_packet_send in silcd/packet_send.c.
2137 * Disconnect the remote connection if it could not be added
2138 to any ID lists in the server. The affected file is
2141 * Check in silc_server_packet_send[_real/dest] that the
2142 socket is not disconnecting and ignore the data if it is.
2143 Affected file silcd/packet_send.c.
2145 * Define inline to __inline on native WIN32 compilation.
2146 Affected file includes/silcwin32.h.
2148 * Added some explicit type casts for inline code since MSVC
2149 require them. Affected files lib/silcutil/silcbuffer.h,
2150 lib/trq/silcdlist.h and lib/trq/silclist.h.
2152 * Print warning in log files from now on if the packet
2153 decryption fails. Affected file silcd/server.c.
2155 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * Changed the `say' client operation's interface to accept
2158 new `type' argument to indicate the type of the message sent
2159 by the library. The application may filter the library's
2160 messages according the type. The affected file is the
2161 lib/silcclient/silcapi.h.
2163 * Added two new functions to lib/silcclient/silcapi.h:
2164 silc_client_del_client and silc_client_del_client_by_id.
2165 Affected file lib/silcclient/idlist.c.
2167 * Moved the clientincludes.h from includes/ to silc/ and
2168 serverincludes.h from includes/ to silcd/.
2170 * The modes for the CMODE and CUMODE are now passed as
2171 uint32 for application with COMMAND_REPLY. The affected
2172 file is lib/silcclient/command_reply.c.
2174 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * /WHOIS without arguments shows client's own information.
2177 Affected file lib/silcclient/command.c.
2179 * Changed PING to not accept any arguments. The specs
2180 says that client can ping only the connected server so
2181 requiring an argument is not needed. Affected file is
2182 lib/silcclient/command.c.
2184 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * Fixed a fatal bug in private message sending and reception
2187 encryption and decryption when using private message keys.
2188 The implementation was incorrect and did not follow the
2189 specification. It causd that some of the message were
2190 lost since it did not use the sending and receiving keys
2191 as the protocol suggests. This has been fixed and will cause
2192 incompatibilities with older clients when sending private
2193 message encrypted with private message keys. Affected files
2194 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2195 and various other in Irssi SILC Client.
2197 Added `responder' boolean argument to the functions
2198 silc_client_add_private_message_key[_ske] to indicate when
2199 the key is added as responder or initiator of the key
2202 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Removed the silc_ske_check_version function and created
2205 a SilcSKECheckVersion callback. Added also a function
2206 silc_ske_set_callbacks that is now used to set all SKE
2207 callbacks. The callback functions are not given to
2208 the SKE functions anymore, but this function is used to
2211 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2213 * Added `silc_version' argument to the silc_client_alloc
2214 to define the version of the application for the library.
2215 The library will use the version string to compare it
2216 against the remote host's (usually a server) version
2217 string. Affected file lib/silcclient/silcapi.h
2219 * Added the KE protocol context to Key Agreement context
2220 in client library so that we can abort the SKE if it
2221 is in process when we get timeout. Affected file is
2222 lib/silcclient/client_keyagr.c.
2224 * Do not resolve the client ID forever if it returns in the
2225 first time that such client does not exist. This was done
2226 for example with private message. Affected file is
2227 lib/silcclient/client_prvmsg.c.
2229 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Do not add regex.h for WIN32. The affected file
2232 includes/silcincludes.h.
2234 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2235 not work yet 100%. It generates the DLL's automatically
2236 when compiling with --with-win32 under cygwin.
2238 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * lib/contrib/regex.c is not compiled on WIN32.
2242 * Added silc_net_get_socket_opt function to the
2243 lib/silcutil/silcnet.h.
2245 * Added includes/silcwin32.h for WIN32 specific includes
2248 * Do not use ptime structure or any of the posix process
2249 functions on WIN32 in lib/silccrypt/silrng.c.
2251 * Added silc_gettimeofday to provide generic function
2252 for struct timeval on all platforms. Added the function
2253 to lib/silcutil/silcutil.h.
2255 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2258 library as they clearly belong there. As a plus side we
2259 can make the actual socket connection routines platform
2262 Added also new generic function silc_socket_read and
2263 silc_socket_write (that used to be silc_packet_[read/write].
2264 The implementation of these are platform specific.
2266 * Added WIN32 specific routines of silc_socket_[read/write]
2267 to lib/silcutil/win32/silcwin32sockconn.c.
2269 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Added preliminary support for native WIN32 compilation under
2272 cygwin (using the -mno-cygwin option for GCC) to the
2273 ./configure.in.pre. The --with-win32 now prepares the
2274 compilation for native WIN32.
2276 * Rewrote the SILC Scheduler interface in the file
2277 lib/silcutil/silcschedule.h. The scheduler is now context
2278 based and does not have anymore any global static scheduler.
2279 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2280 and created lib/silcutil/win32 directory for WIN32 based
2283 * Added Unix specific network routines to the
2284 lib/silcutil/unix/silcunixnet.c and the old
2285 lib/silcutil/silcnet.c includes now only generic routines.
2287 Added WIN32 specific network routines to the
2288 lib/silcutil/win32/silcwin32net.c.
2290 * Added Unix specific utility functions from the
2291 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2293 * Added WIN32 SILC Scheduler to the file
2294 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2297 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Do not handle JOIN notify in the server if the target client
2300 is not registered (idata->registered == FALSE). The affected
2301 file is silcd/packet_receive.c.
2303 * Update the nickrec->founder in event_cumode in the Irssi SILC
2304 client. Affected file irssi/src/silc/core/silc-channels.c.
2306 * Fixed the CUMODE_CHANGE notify handling in the server when
2307 server and router are announcing their clients on channels.
2308 Now the mode changes are saved and notified correctly. The
2309 affected file is /silcd/packet_receive.c.
2311 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2312 They really did not replace the cache entry in the ID Cache.
2313 Now they do that. Affected file silcd/idlist.c.
2315 * Fixed the KICK notify handling in the Irssi SILC client to
2316 update the channel records so that the kicked client does not
2317 appear to be on the channel. The affected file is
2318 irssi/src/silc/core/silc-channels.c.
2320 * Always update the conn->current_channel when executing command
2321 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2323 * Fixed the KILL notify handling in Irssi SILC client to remove
2324 the killed client on all channels.
2326 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Fixed the silc_parse_command_line to remove extra spaces
2329 from the start and end of the arguments. Affected file is
2330 lib/silcutil/silcutil.c.
2332 * Cancel and free any active protocol in the function
2333 silc_server_close_connection. Affected file silcd/server.c.
2335 * Cancel and free any active protocol in the function
2336 silc_client_close_connction. Affected file is
2337 lib/silcclient/client.c.
2339 * Do not execute the KILL command for clients that are in
2340 history (ie. they are not in the network). Affected file is
2343 * Fixed KILL notify handling, client does not crash anymore.
2344 Affected file irssi/src/silc/core/silc-channels.c.
2346 * Reduced the default packet buffer size from 2048 to 1024 in
2347 lib/silccore/silcpacket.c.
2349 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2350 counter to the SKE context that is incresed when the SKE library
2351 performs async operation outside the library. If the outside
2352 process frees the SKE context and FREED status will be set
2353 and the library will detect after the sync operation that the
2354 libary is freed. The affected files are
2355 lib/silcske/silcske[_status].[ch].
2357 * Resolve the client entry information in the function
2358 silc_client_channel_message to assure that NULL pointer is not
2359 passed as client entry to the application. */
2361 * Fixed the task timeout calculation to assure that there is
2362 never negative timeouts. The affected file is
2363 lib/silcutil/silcschedule.c.
2365 * Fixed the channel user mode notification sending in server.
2366 It was sent point-to-point to the router (or to server by router)
2367 but it needs to be destined to a channel. The routines now
2368 supports sending the channel user mode notifys to the channels
2369 when announcing clients and channels. Affected files are
2370 silcd/server.c and silcd/packet_receive.c.
2372 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2373 It did not actually replace the old channel entry in the cache.
2374 Affected file lib/silcclient/client_notify.c.
2376 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Fixed a possible crash in silc_packet_send_prepare. It now
2379 assures always that there is enough space in the buffer and
2380 at the tail area of the buffer (for MAC).
2382 Fixed the inbound buffer reallocation in silc_packet_read.
2383 It was old code and did not handle the reallocation correctly.
2386 The affected file is lib/silccore/silcpacket.c.
2388 * Fixed buffer overflow in silc_parse_nickname in the file
2389 lib/silcutil/silcutil.c.
2391 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2393 * make install generates new server keys only if there is not
2396 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2399 Added check that if the NOREPLY is set then we will not send
2400 the away message. This avoids infinite loop of away messages
2401 if both clients are away. The affected file is
2402 lib/silcclient/client_prvmsg.c.
2404 * Fixed client crash if /NICK was given without arguments.
2405 Affected file lib/silcclient/command.c.
2407 * Server does not send the invite list in INVITE command back
2408 to the client if the list was not altered. Added this notion
2409 to the protocol spec as well. Affected file silcd/command.c.
2411 Fixed possible crash in INVITE command by checking the
2412 value of silc_server_get_client_route command.
2414 * Fixed the INVITE notify type handling. The arguments are now
2415 taken in correct order and client does not crash. The affected
2416 file is irssi/src/silc/core/silc-channels.c.
2418 Removed the "Inviting xxx to channel" message from the
2419 client library away and let the application handle it.
2420 Affected file lib/silcclient/command.c. Added that message
2421 to Irssi SILC client's message formats.
2423 * Fixed CMODE command crash in client. It now checks the
2424 amount of arguments correctly and does not crash. The affected
2425 file is lib/silcclient/command.c.
2427 * Do not create new channel automatically in silc_channels_join
2428 but check whether the channel by that name already exists.
2429 Affected file irssi/silc/core/silc-channels.c.
2431 * Do not send the SERVER_SIGNOFF to router if the disconnected
2432 entity was the router. Affected file silcd/server.c.
2434 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2435 SILC client as it was missing from there.
2437 Added the handling of the KICK notify to the Irssi SILC client
2438 as it was missing. Added "you have been kicked" message to
2439 Irssi SILC client's message modules formats.
2441 Added the handing of the KILL notify to the Irssi SILC client
2442 as it was missing. Added the kill message module formats
2445 The affected file is irssi/src/silc/core/silc-channels.c.
2447 * The router did not save the channel mode the server announced.
2448 Affected file silcd/packet_receive.c.
2450 * Fixed a possible crash in INFO command in server. If the
2451 server did not provide the server info it crashed. Affected
2452 file silcd/command.c.
2454 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Fixed the GETKEY command in the server to check also the
2457 global list. Otherwise the GETKEY would not work correctly
2458 in normal SILC server. Affected file silcd/command.c.
2460 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Fixed GETKEY crash, it crashed if the command did not succseed.
2464 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2467 is now real and not just an macro interface to GMP.
2469 Removed the entire GMP from the source tree and imported new
2470 NSS MPI library instead. Reason for removing GMP is that it is
2471 extremely large and compiles extremely slow. The NSS MPI
2472 is only a few files and compiles in less than 10 seconds.
2473 The speed is also about the same as GMP. The MPI is imported
2474 to lib/silcmath/mpi.
2476 If the system has GMP installed we will still use the GMP.
2477 If it is not then the NSS MPI will be compiled.
2479 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Merged a long nickname (127 characters long) crash bugfix from
2482 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2484 * Merged a freed memory reference bugfix from Irssi CVS tree.
2485 Affected file irssi/src/core/commands.c.
2487 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * Added the server's public key sving and verification to the
2490 server when performing the SKE. This was missing and the
2491 remote server's (or router's) public key was accepted without
2492 checking whether we have it previously or trust it at all.
2493 Affected file silcd/protocol.c.
2495 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Check in the silc_server_timeout_remote if protocol is active
2498 and make sure that the protocol's final callback is called so
2499 that all memory if freed. Affected file silcd/server.c.
2501 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * silc_server_whois_send_reply crashed the server if the nickname
2504 was 127 characters long. Affected file silcd/command.c.
2506 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Added sanity check to the silc_server_new_client. If the hostname
2509 is provided inside username then check that the provided hostname
2510 really is the same as the resolved one. If the hostname was not
2511 resolved then check it from the public key. Affected file is
2512 silcd/packet_receive.c.
2514 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2515 if the server disconnected us and the connection is not valid
2516 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2518 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2519 the library to the lib/silcutil/silcutil.[ch].
2521 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2523 * Close log file after open. Affected file
2524 lib/silcutil/silclog.c.
2526 * Check whether sock == NULL in silc_client_send_packet and return
2527 if it is. Affected file lib/silcclient/silcclient.c.
2529 * Check rec->entry == NULL in the Irssi SILC Client before
2530 sending the channel message. Affecte file is
2531 irssi/src/silc/core/silc-servers.c.
2533 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2535 * Merged a splitted window bugfix from Irssi CVS tree. The
2536 affected file is irssi/src/fe-text/textbuffer-view.c.
2538 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2539 It did not print nickname.
2541 * Improved the distributions system a bit.
2543 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2546 irssi/src/fe-text/gui-window.c.
2548 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2549 to in-active server. The affected file is
2550 irssi/src/silc/core/client_ops.c.
2552 * Resolve the client in USERS command reply if the entry does
2553 not have username resolved. The affected file is
2554 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2555 command to WHOIS command to really resolve stuff. The USERS
2556 is not used any more in any critical section so WHOIS can
2557 be used even though it might be slower than IDENTIFY.
2559 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2562 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Changed the protocol API a bit more consistent in the
2565 lib/silccore/silcprotocol.[ch].
2567 * Changed the following headers to ROBODoc format:
2569 lib/silccore/silcpayload.h
2570 lib/silccore/silcprotocol.h
2571 lib/silccore/silcsockconn.h
2573 All core library headers are now formatted.
2575 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Fixed a bug in Irssi SILC client; do not show that you are
2578 server/router operator if you really are not. Affected file is
2579 irssi/src/silc/core/client_ops.c.
2581 * Renamed silc_command_free_payload to silc_command_payload_free.
2582 Affected file lib/silccore/silccommand.h
2584 * Added silcmath.h to include the prototoypes of various routines
2585 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2588 * Changed the following headers to ROBODoc format:
2590 lib/silccore/silcchannel.h
2591 lib/silccore/silccommand.h
2592 lib/silccore/silcid.h
2593 lib/silccore/silcidcache.h
2594 lib/silccore/silcmode.h
2595 lib/silccore/silcnotify.h
2596 lib/silccore/silcpacket.h
2597 lib/silcmath/silcmath.h
2599 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added checking to the server code not to start the server if
2602 ciphers and stuff are not configured properly. Affected files
2603 silcd/serverconfig.[h] and silcd/server.c.
2605 * Changed the layout of the header files of the public interfaces
2606 in the SILC libraries. The new layout supports ROBODoc
2607 documentation tool (and some others) so that it is easy to create
2608 a library reference manual. All the other headers and source
2609 code must still follow the CodingStyle document. Also source
2610 code must not include these ROBODoc stuffs, only the headers.
2611 Furthermore, all public interface headers must now be named
2612 by using `silc' prefix, example: silcapi.h, silccipher.h.
2613 Some files were renamed due to this. All the other headers
2614 must not be used as public interfaces. I will update the
2615 CodingStyle document later. Changed following headers, so far:
2617 lib/silcclient/silcapi.h
2618 lib/silccore/silcauth.h
2619 lib/silccore/silcprivate.h
2620 lib/silccrypt/silcdh.h
2622 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Removed silc_client_packet_send_flush from the client library
2627 as it is not needed. Affected file lib/silcclient/client.[ch].
2629 * Added printing of message of unresolved authentication method
2630 to the Irssi SILC client. Added it to the module formats.
2631 Removed the same message from the client library.
2633 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Added new distribution feature, DISTLABEL. Every distribution
2636 can define own preprocessor label that can be used in the
2637 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2638 file distributions, acconfig.h.pre and prepare.
2640 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2642 * Added Makefile.defines_int to include the actual definitions
2643 for Makefile.defines.in. Tested the new distribution system,
2644 created distributions and tested installation.
2646 * Added AWAY message printing to the Irssi SILC client. Added
2647 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2649 * Added SCONNECT command to call the SILC's CONNECT command.
2650 Cannot use CONNECT directly since Irssi uses that internally.
2651 Affected file irssi/src/silc/core/silc-servers.c.
2653 Added ACTION local command. It is same as ME command but takes
2654 the channel as mandatory argument.
2656 Rewrote some of the Irssi's help files to suite for SILC
2659 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2661 * Added Makefile.defines[.in] that should for now on be included
2662 in all Makefile.am file in the source tree. That file includes
2663 all common compilation definitions for SILC source tree.
2665 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Minor changes to the ./prepare script to change the package
2668 name according the distribution name to the configure.in.
2670 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Created new distribution system. Added file `distributions'
2673 that defines all the distributions that can be created out of
2674 the SILC source tree. The ./prepare script now reads that
2675 file to determine how to prepare the distributions. The
2676 first argument to the ./prepare is the name of the distribution
2677 and second is the version of the distribution. If given
2678 without arguments it creates the default (toolkit) distribution
2679 with the default version (defined in ./prepare).
2681 All Makefile.am files that are subject to the distributions
2682 are now named as Makefile.am.pre. These are ./Makefile.am
2683 and lib/Makefile.am. Others may be changed later.
2685 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Added invite list, ban list, some key management and connection
2688 error message printing to module formats in the Irssi SILC client.
2690 * Added new silc_client_set_away_message to set the away message
2691 that is back to the person who sent private message. The
2692 affected file lib/silcclient/silcapi.h and the
2693 lib/silcclient/client_prvmsg.c.
2695 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Fixed the private message sending in the Irssi SILC client,
2698 added local command KEY to the Irssi SILC client.
2700 Added key management and key agreement message formats to the
2701 irssi/src/fe-common/silc/module-formats.[ch].
2703 Added USERS (alias WHO) printing, server/router operator
2704 indication and LIST command printing to the module formats.
2706 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Fixed channel joining notify handling, cumode notify handling
2709 from Irssi SILC client.
2711 * Added SILC specific module-formats to the Irssi SILC client so
2712 that SILC specific message hilighting, colors etc is possible.
2713 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2715 Added channel mode, channel user mode, actions, notices,
2716 whois and whowas printing to the the module-formats.c.
2718 * Fixed a bug in channel deletion in the server. The channel
2719 is not left to the cache even if the channel founder auth mode
2720 is set when there are no users anymore on the channel. Affected
2721 file silcd/server.c.
2723 * The silc_net_localhost now resolves the entire hostname including
2724 the domain name. Affected file lib/silcutil/silcnet.c.
2726 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Changed the ask_passphrase client operation to be ascynchronous.
2729 It has now a completion callback and a context that the
2730 application must call after it has got the passphrase from
2731 the user. Affected files lib/silcclient/silcapi.h,
2732 lib/silcclient/protocol.c, lib/silcclient/command.c and
2735 Added SilcAskPassphrase callback that the application calls
2736 to deliver the passphrase to the library.
2738 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2739 The public key verification and especially a certificate
2740 verification is asynchronous procedure.
2742 Added new SILC_SKE_STATUS_PENDING status to indicate the
2743 request is pending and a callback will be called to finalize
2746 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2747 indicate that remote end did not send its public key (or
2748 certificate), even though we require it. Added check for this
2749 condition in the SKE. This was a security bug, now fixed.
2751 Defined new SilcSKEVerifyCbCompletion callback that is called
2752 when the verification process is completed.
2754 The affected files lib/silcske/silcske_status.h and
2755 lib/silcske/silcske.[ch].
2757 * Changed the verify_public_key client operation to be async
2758 as well. Defined SilcVerifyPublicKey callback that is used to
2759 indicate the success of the public key verification process.
2761 Changed the server and client to use the new async client
2764 * Changed the Irssi SILC client's internal scheduler to be called
2765 twice as many times as it used to be. As a result the client
2766 should be a bit faster now. Affected file is
2767 irssi/src/silc/core/silc-core.c.
2769 * Added support to Irssi SILC client of asynchronous public key
2770 verification and passphrase inquiry. Affected file is
2771 irssi/src/silc/core/silc-core.c.
2773 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Do not say "You have left channel %s" in client library.
2776 Moved it to the application. Affected files are
2777 lib/silcclient/command.c and silc/client_ops.c.
2779 * Fixed silc_client_get_clients. Command context was not
2780 duplicated and was freed memory in the callback. Affected
2781 file lib/silcclient/idlist.c.
2783 * Do not say "you are now talking..." on JOIN command in the
2784 client library. The appliation must handle it.
2786 * Do not say ".. changed topic to" in command reply in the
2787 client libary. The application must handle it.
2789 * Fixed TOPIC command sending in the client library.
2791 * Fixed a memory leak in silc_client_command_free in the file
2792 lib/silcclient/command.c.
2794 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Imported a modified version of Irssi client to the source tree.
2797 The Irssi will be used to create a new client called
2798 Irssi SILC. Imported to irssi/.
2800 Added silc_core_init_finish function to the Irssi. Affected
2801 file irssi/configure.in.
2803 A lot changes in the Makefile.ams around the irssi tree.
2805 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Do not rehash if the new size is same as the old size of the
2808 hash table, in the silc_hash_table_rehash*. The affected file
2809 lib/silcutil/silchashtable.c.
2811 * Replaced hash_table_del_by_context calls from the server
2812 (when channel->user_list and client->channels) to the
2813 hash_table_del as it is sufficient and faster.
2815 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Added silc_hash_table_list, silc_hash_table_get and the
2818 SilcHashTableList structure to provide an alternative way to
2819 traverse the hash table. The affected files are
2820 lib/silcutil/silchashtable.[ch].
2822 * Changed the server's idlist routines to use the hash table
2823 routines to optimize the code.
2825 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Replaced the client entry's `channel' list and channel entry's
2828 `user_list' list to hash tables for optimized lookup. Changed
2829 the code to use the hash table interface around the code.
2830 Affected file lib/silcd/idlist.[ch].
2832 * Added `auto_rehash' boolean argument to the function
2833 silc_hash_table_alloc to indicate whether the hash table should
2834 auto-rehash when it thinks is appropriate time. It will
2835 increase the hash table size if the there is twice as much
2836 entries in the table than the size of the table, and will
2837 decrease the size if there are twice as less entries than
2838 the size of the table.
2840 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2844 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * silc_idcache_purge_by_context deletes the entry now by context
2847 as it is supposed to do. Affected file lib/silccore/idcache.c.
2849 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2850 client is not anymore valid (WHOWAS givens the info) and not
2851 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2853 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Removed the `data' and `data_len' arguments from the ID Cache
2856 interfaces and added `name' argument. ID Cache does not handle
2857 anymore the binary data only a names associated with given ID.
2859 * When hashing a Client ID with silc_hash_id the entire ID is
2860 not hashed anymore, instead only the hash of the Client ID is
2861 hashed. This way we can access the Client ID from the cache
2862 with Client ID but with the hash of the ID (which is a hash of
2863 the nickname) as well without any difference in performance.
2865 Added also silc_idcache_find_by_id_one_ext to do one on one
2866 searching when we have the actual ID. Added also function
2867 silc_hash_client_id_compare. The affected files are
2868 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2870 * When hashing the name associated with a ID it is always done
2871 in lowercase. This way we can access the cache without worrying
2872 about case-sensitivity, even though, for example nicknames are
2875 * Fixed a bug in server with channel message sending. It put
2876 wrong ID type as destination ID. The affected file
2877 silcd/packet_send.c.
2879 * silc_idcache_del_by_context now deletes from all hash tables
2880 by context. Affected file lib/silccore/idcache.c.
2882 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Changed the client library to use the new ID Cache interface.
2885 Changes around the source tree.
2887 * Added silc_hash_table_rehash_ext to rehash with specific
2888 hash function. Affected file lib/silcutil/silchashtable.[ch].
2890 * Added silc_hash_string_compare to compare two strings in the
2891 hash table. Affected file lib/silcutil/silcutil.[ch].
2893 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Added new function silc_idcache_del_by_context into the
2896 lib/silccore/idcache.[ch].
2898 * Changed the server's ID list routines to use the new ID Cache
2899 interface. Changes around the source tree.
2901 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Added silc_hash_table_del[_by_context]_ext functions in to the
2904 lib/silcutil/silchashtable.[ch].
2906 Removed silc_hash_table_find_all* routines and added new
2907 silc_hash_table_find_foreach to replace them.
2909 Added silc_hash_table_replace_ext function as extended
2910 replacing function. Separated the simple hash table interface
2911 from the extended hash table interface in the file
2912 lib/silcutil/silchashtable.h.
2914 * Fixed minor bugs and changed it to use some of the new
2915 hash table functions in lib/silccore/idcache.c
2917 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added new function silc_hash_table_find_all to return all keys
2920 in the hash table by the specified key. As the hash table is
2921 collision resistant it also makes it possible to have several
2922 duplicate keys in the hash table. This function may be used to
2923 find all of the keys from the hash.
2925 Added user_context arguments to the SilcHashFunction,
2926 SilcHashCompare and SilcHashDestructor to deliver user specified
2929 Added new fuctions silc_hash_table_find[_all]_ext to do
2930 extended lookup with specified hash and compare functions and
2931 specified user contexts.
2933 Added new function silc_hash_table_add_ext to add the key
2934 with specified hash function and user context.
2936 Added new function silc_hash_table_foreach to traverse all
2937 entrys in the hash table. Added SilcHashForeach callback
2940 Added new function silc_hash_table_del_by_context to delete
2941 the entry only if the context associated with the key matches.
2943 Affected files are lib/silcutil/silchashtable.[ch].
2945 * Removed silc_hash_[server/client/channel]_id and added just
2946 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2947 silc_hash_id_compare to compare two ID's using as the hash table
2948 comparison function. Added also silc_hash_data to hash
2949 binary data and silc_hash_data_compare to compare it.
2951 * Removed silc_idlist_find_client_by_hash as it is not needed
2952 anymore. Affected file silcd/idlist.[ch].
2954 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2955 to use internally the SilcHashTable. The new ID Cache is a lot
2956 faster than the old one. Some of the ID Cache interface was also
2957 rewritten and obsolete and stupid functions were removed.
2959 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Added entry_count field to the SilcHashTable to keep the number
2962 of the entries in the table. Implemented the function
2963 silc_hash_table_rehash. Added new function
2964 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2966 Fixed a minor bug in silc_hash_table_free.
2968 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2969 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2970 into the lib/silcutil/silcutil.[ch].
2972 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Implemented a collision resistant hash table into the
2975 lib/silcutil/silchashtable[ch]. See the header and the source
2976 for the SilcHashTable API.
2978 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Merged dotconf version 1.0.2 into lib/dotconf.
2982 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Do not compile anything in lib/silcsim/* if the SIM support
2985 is not enabled. The tree should now compile without problems
2988 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2990 * Compiled the SILC under cygwin. Compiled and tested briefly
2991 without problems. More tests needed. The SIMs didn't compile
2994 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2996 * Fixed possible crash in silc_get_username in the
2997 lib/silcutil/silcutil.c.
2999 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Fixed a va_arg in silc/client_ops.c.
3003 * Oops, RC5 routines were named AES and caused some problems
3004 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3006 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Added new SilcIDIP structure into the lib/silccore/id.h and
3009 replaced the old `ip' fields from all SILC ID's to that type.
3010 This is a step towards IPv6 support.
3012 The silc_id_get_len takes now the ID as an extra argument.
3013 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3014 both IPv4 and IPv6 based ID's.
3016 The affected files are lib/silccore/id.[ch] and other files
3017 around the tree using these routines.
3019 * Removed the ID length arguments in server from various
3020 silc_server_send_notify_* routines -> they are not needed
3023 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Fixed memory leak in silc_encode_pem_file in the file
3026 lib/silcutil/silcutil.c.
3028 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Check minor version as well in the SKE. Affected files are
3031 silcd/protocol.c and lib/silcclient/protocol.c.
3033 * Added --identifier option to the server so that an identifier
3034 can be when creating the public key for the server. Affected
3035 file is silcd/silcd.c.
3037 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3038 lib/silccrypt/silcpkcs.c.
3040 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Register default ciphers and stuff when using -C option with
3043 the server. Affected file sildc/silcd.c.
3045 * Put back the servers public key filename format, it is better
3046 than the new one. For now, the client keys are saved with the
3047 new filename format. The affected file silc/client_ops.c.
3049 * Implemented the Cipher API for the rest of the ciphers that
3050 did not implement it or implemented it the wrong way.
3052 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Register default ciphers and stuff when using the -S option
3055 in the client. Affected file silc/silc.c. Same also when
3056 creating new key pair with -C option.
3058 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Fixed the silc_verify_public_key client operation function to
3061 save the public keys differently. The fingerprint is now
3062 used as filename and not the hostname. This way also the
3063 client keys are saved uniquely and not with hostnames. The
3064 affected file is silc/client_ops.c.
3066 * Trimmed the silc_hash_fingerprint function to remove extra
3067 whitespaces from the end of the fingerprint. The affected
3068 file is lib/silccrypt/silchash.c.
3072 * Added silc_cipher_register_default function to register all
3073 default ciphers. It can be used when configuration files
3074 does not exist and the application does not want any specific
3075 ciphers in any specific order.
3077 The SilcDList is now used as silc_cipher_list dynamically
3078 allocated cipher list. Removed the static list all together
3079 and now all ciphers must be allocated to the dynamic list.
3080 The silc_cipher_alloc routine was changed to check only the
3083 All silc_cipher_* routines that used to return int returns
3086 The affected files lib/silccrypt/silccrypt.[ch].
3088 * The same thing was done to silc_hash_* as for silc_cipher_*
3089 routines. Affected files lib/silccrypt/silchash.[ch].
3091 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3092 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3093 Added also silc_pkcs_[un]register[_default] functions.
3094 Removed the data_context from the PKCS API.
3096 * Added silc_hmac_register_default function to register default
3097 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3098 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3099 to unregister all hmacs at once.
3101 * Register the default ciphers, hash functions, PKCSs and HMACs
3102 if client's configuration file does not exist. The affected
3105 * The client did not load the hash functions from the SIM
3106 modules at all. Added support for this. Affected file is
3107 silc/clientconfig.c.
3109 * When decoding public key with silc_pkcs_public_key_decode, check
3110 the supported algorithm only if PKCS are registered. Affected
3111 file lib/silccrypt/silcpkcs.c. The same was done with the
3112 silc_pkcs_private_key_decode.
3114 * Fixed the SILC List routines to keep the list always in order.
3115 It used to change the list's order when traversing the list but
3116 not it preserves the order. Affected file lib/trq/silclist.h.
3118 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added the client library to use the SilcSocketConnection's
3121 reference counter (by silc_socket_dup) to prevent the bug that
3122 the socket object may be freed underneath async operation.
3124 * The name resolv library checking fixes in the configure.in.pre.
3127 * Created new version of the protocol drafts for future
3128 development. The -03 drafts are the ones that will be changed
3129 in the trunk now and the -02 will remain as they are.
3131 * Send list of CUMODE notifys to the router when announcing
3132 the channel users to the router. Affected file silcd/server.c.
3133 If the router receiving channel founder CUMODE for a channel
3134 that already has channel founder it will send CUMODE notify
3135 to the sender to remove the channel founder rights from the
3136 announced client. Affected file silcd/packet_receive.c.
3138 * The CUMODE notify may now use Server ID as well as the entity
3139 who changes the mode. Updated protocool specs.
3141 * Updated INSTALL and README files.
3143 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * New web pages in the http://silc.pspt.fi. The pages was
3150 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Implemented the [DenyConnectin] config section in the server.
3153 Added silc_server_config_denied_conn to check whether incoming
3154 connection is denied. Affected file silcd/serverconfig.[ch].
3156 * Do not check the ports when checking the incoming configuration
3157 data if the port is 0, meaning any. Affected file is
3158 silcd/serverconfig.c.
3160 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Fixed buffer overflow in silc_string_compare in the file
3163 lib/silcutil/silcutil.c.
3165 * Fixed double free in silc_server_command_leave in the file
3168 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Fixed the version checking in the server. Affected file is
3173 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Fixed the configuration data fetching when accepting new
3176 connections in the server. Affected file silcd/server.c.
3178 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * Added `sender_entry' argument to the function
3181 silc_server_packet_relay_to_channel so that we can check
3182 whether some destination actually belongs to the same route
3183 the sender belongs (ie, we must not resend the packet to the
3184 sender). Affected file silcd/packet_send.[ch].
3186 * Added `servername' field to the SilcClientEntry in the server
3187 to hold the name of the server where client is from. Affected
3188 file is silcd/idlist.h.
3190 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3192 * Moved the channel message encrypting in the router betwen
3193 router connections from silc_server_channel_message to the
3194 silc_server_packet_relay_to_channel since we want to check
3195 whether we have anybody channel before encrypting anything.
3196 Affected files silcd/packet_[receive/send].c.
3198 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Fixed the [AdminConnection] server config section to support
3201 multiple entries. Affected file silcd/serverconfig.c.
3203 * Added support into the server to check the validity of the
3204 incoming connection before executing any KE or authentication
3207 * The connection configuration is now saved to the KE and
3208 connection auth protocol contexts and not fetched anymore in
3209 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3211 * The local hosts listenning address and port is also resolved
3212 now when starting the server. We want to have the socket object
3213 to include the real address and port for the listener. Added
3214 new function silc_net_check_local_by_sock into the files
3215 lib/silcutil/silcnet.[ch].
3217 * Fixed a broadcast bug in server -> do not broadcast if we
3220 * Fixed a routing bug. Do not route broadcast packets ever.
3221 Broadcast packets must be processed always and not routed since
3222 they may be destined to some other host than yourself and thus
3223 would get routed without no good reason. Affected file is
3226 * Added function silc_server_config_is_primary_route to check
3227 whether primary router connection has been configured (a router
3228 configuration that we are initiating). If there is not, we
3229 will assume that there is only two routers in the SILC network
3230 and we will use the incoming router connection as our primary
3231 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3233 * Changed the order of the broadcasting. Broadcast _after_ the
3234 packet has been processed not before. Affected file is
3237 * Fixed a [ClientConnection] parsing bug. The port was never
3238 parsed correctly thus resulting to port 0. Affected file
3239 silcd/serverconfig.c.
3241 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3242 argument and did not set the broadcast packet flag. Affected
3243 file silcd/packet_send.c. Fixed same bug in the function
3244 silc_server_send_notify as well.
3246 * If we receive NEW_ID packet for our own ID in the server, ignore
3249 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Removed the nickname from the Private Message Payload.
3254 Updated the code and the protocol specs.
3256 * Updated protocol specs for submitting to the IETF.
3258 * Tweaked the Random Number Generator a bit. Affected file
3259 lib/silccrypt/silcrng.c. Exported a new function
3260 silc_rng_[global]_add_noise which can be used to add more
3263 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3265 * Do not parse packets with different timeout when protocol
3266 is active -> may cause problem with rekey. Affected file
3269 * When server receives signoff notify it must not create
3270 new channel key if the client is on any channels since the
3271 sender of the signoff notify will create it.
3273 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Added printing of error messages during SKE protocol from the
3276 failure packet sent by server during SKE. Affected file
3279 * Removed the client's failure_callback handling with timeout
3280 and handle it immediately when received.
3282 * The SKE library returned wrong type in SUCCESS and FAILURE
3283 packets. They must be 32 bit MSB not 16 bit MSB.
3285 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Ok, rewrote the logic of the re-key and now it seems to work.
3288 I tested it on high traffic with frequent re-keys without
3289 problems. Added hmac_receive (and renamed hmac to hmac_send)
3290 in SilcClientConnection in lib/silcclient/client.h and
3291 in SilcIDListData in silcd/idlist.h. Also, removed the
3292 SilcPacketParserContext's cipher and hmac fields as they are
3293 not needed anymore and actually caused some problems when
3294 the ciphers and hmac's changed underneath the packet parser.
3296 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * If re-key protocol is active then process the incoming packets
3299 synchronously since we must assure that icoming packets encrypted
3300 with the old key is processed before the new keys is set to
3301 use. This is true other packets than for REKEY packets.
3302 Affected file silcd/server.c. The same was done to client library
3303 as well, affected file lib/silcclient/client.c.
3305 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Fixed bug in client and server to accept the force send if
3308 the packet is send from silc_[server/client]_packet_process
3309 function. Otherwise the packets are never delivered, oops.
3311 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Disable force sending of packets when REKEY protocol is active.
3314 We must assure that no packet is sent directly when rekey is
3315 performed. All packets must be sent through packet queue.
3316 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3317 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3318 function is silc_[server/client]_packet_send_real to check
3321 * Replaced the SIM paths from example config files to
3322 /usr/local/modules. Also, make install creates now
3323 /usr/local/silc/logs directory to hold all the SILC server
3326 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Made the configure.in.pre work on Solaris. Patch by salo.
3330 * Made all ciphers compatible with non-x86 machines. Defined
3331 CBC mode macros into lib/silccrypt/ciphers_def.h.
3333 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Fixed the make install.
3337 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * When MAC computation fails the silc_packet_decrypt returned 0
3340 even though it was supposed to return -1. Fixed this. The
3341 affected file is lib/silccore/silcpacket.c.
3343 * Do not replace the config files in /etc/silc (in make install)
3344 if they already exist. Affected file ./Makefile.am.
3346 * Do not send re-key packets immediately but through packet queue.
3347 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3349 * Changed silc_net_check_host_by_sock to return FALSE if the
3350 IP/DNS could not be resolved. Though, it returns the IP address
3351 now even if it could not resolve it (but returns also FALSE).
3352 Affected file lib/silcutil/silcnet.[ch].
3354 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Added silc_pkcs_decode_identifier to decode the public key's
3357 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3358 Added also silc_pkcs_free_identifier. Added also new context
3359 SilcPublicKeyIdentifier.
3361 * Added -S option to the silc client. It is used to dump the
3362 contents of the specified public key file.
3364 * Changed the PKCS api to return the public key length when
3365 setting the public key.
3367 * Fixed a fatal bug in the public and private key file loading.
3368 Affected file lib/silccrypt/silcpkcs.c.
3370 * Execute the packet parsing for client with zero (0) timeout
3371 if the protocol is active. Affected file silcd/server.c.
3373 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Made the key generation options to the silcd program. Added
3376 -C option, equivalent to client's option.
3378 * Added new [ServerKeys] config section to the server. It
3379 configures the server's public and private key.
3381 * Defined generic Public Key Payload into the protocol
3382 specification to send specific type of public keys and
3385 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3386 public key or certificate.
3388 * Implemented the GETKEY command to the server and to the
3389 client library and on user interface.
3391 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Made preliminary `make install' work.
3395 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Added SilcServerRekey context into silcd/idlist.h.
3399 * Added the PFS support as defined in the specification to the
3400 SKE protocol. Affected files lib/silcske/*.c.
3402 * Added `ske_group' field to the SilcServerRekey context to hold
3403 the number of the SKE group that is used with PFS in re-key.
3404 Affected file silcd/idlist.h.
3406 * Added PFS re-key support to the server. Affected file is
3409 * Added silc_protocol_cancel to cancel execution of the next
3410 state of the protocol. Affected file is
3411 lib/silccore/silcprotocol.[ch].
3413 * Added the re-key support with and without PFS to the client
3414 library. Re-key is performed once in an hour, by default.
3416 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3417 Added silc_client_rekey_callback and silc_client_rekey_final.
3418 Affected files are lib/silcclient/protocol.[ch] and
3419 lib/silcclient/client.[ch].
3421 * Removed the `hmac_key' and `hmac_key_len' fields from the
3422 SilcClientConnection structure; not needed. Affected file is
3423 lib/silcclient/client.h.
3427 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Do not ask whether user wants to use the negotiated private key
3430 for private messages, just use it. Affected file is
3431 silc/local_command.c.
3433 * Added `send_enc_key' and `enc_key_len' fields to the
3434 SilcIDListData structure since they are needed in the re-key
3435 phase. Affected file is silcd/idlist.[ch].
3437 * Implemented the simple re-key protocol into the server.
3438 Affected files silcd/server.c and silcd/protocol.[ch]. The
3439 re-key will be performed once in an hour, by default.
3441 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3442 Added silc_server_rekey, silc_server_rekey_callback and
3443 silc_server_rekey_final.
3445 * Removed Tunneled flag from the protocol. Updated the code
3446 and the specifications.
3448 * Adde `pfs' field to the SilcIDListData to indicate whether
3449 the PFS is to be performed in the re-key. Affected file is
3452 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3455 int64 of at least the xintXX size. If void * is less that 4
3456 bytes uint32 * will be used. Defined bool as boolean.
3458 * Changed _ALL_ unsigned long and unsigned int to uint32,
3459 unsgined short to uint16 in the source tree.
3461 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3462 not handle clients that has entry->data.registered == FALSE.
3463 They are not in the network anymore. Affected file is
3466 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Implemented the sending of the SERVER_SIGNOFF notify in the
3469 server. Affected file is silcd/server.c.
3471 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3472 Added also silc_notify_payload_encode_args into the
3473 lib/silccore/silcnotify.[ch].
3475 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3476 Affected file silcd/packet_receive.c.
3478 * Implemented the SERVER_SIGNOFF notify handling in the client
3479 library. Affected file lib/silcclient/client_notify.c. Also,
3480 implemnted the printing of the SERVER_SIGNOFF info to the
3481 application. Affected file silc/client_ops.c.
3483 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3484 if the deleting was successful. Affected file silcd/idlist.[ch].
3486 * Added support for public key authentication in the connection
3487 authentication protocol in the client library. Affected file
3488 lib/silcclient/protocol.c.
3490 * Changed the server's silc_idlist_get_clients_by_* interface
3491 to support already allocated array so that new entries may be
3492 added to pre-allocated array. Affected file silcd/idlist.[ch].
3493 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3494 and command replies.
3496 * All command reply functions in the server now calls the
3497 pending command callback even if error occured. This way the
3498 error will be delivered to the client as well. Affected files
3499 silcd/command.c and silcd/command_reply.c.
3501 * Fixed INFO command to return local server's info if no server
3502 was provided. Affected file lib/silcclient/command.c.
3504 * Removed RESTART command for good. Updated the code and the
3507 * Rewrote parts of the task system. It is a bit simpler now.
3508 Removed unsued task priorities. The affected files are
3509 lib/silcutil/silctask.[ch].
3511 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Moved the USERS printing from the library to the application.
3514 Affected files lib/silcclient/command.c and silc/client_ops.c.
3516 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Added channel key re-key support. The re-key is perfomed
3521 only by the router and is done once in an hour. Added `rekey'
3522 field to the SilcChannelEntry in the server. Affected files
3523 silcd/server.c and silcd/idlist.h.
3525 * Added silc_task_unregister_by_context into the file
3526 lib/silcutil/silctask.[ch].
3528 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Added SILC_UMODE_GONE mode to indicate when the client is not
3531 present in the SILC network. Added also support to the local
3532 command AWAY that will set this mode. Added support of showing
3533 "xxx is gone" in WHOIS command. The USERS command shows the
3534 gone status as well.
3536 * Fixed setting server and router operator privileges in the
3537 server's UMODE command. Affected file silcd/command.c.
3539 * Merged the SKE KE1 and KE2 payloads into one payload. The
3540 new KE payload is equivalent to the old KE2 payload.
3542 Cleaned up the SKE Start Payload parsing. It now uses the
3543 simple buffer unformatting to do the parsing. A lot faster
3546 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3547 to the SKE that is used to indicate whether both of the SKE
3548 parties should perform authentication. By default only the
3549 responder performs authentication. By setting this flag also
3550 the initiator must do authentication. By default it is unset
3551 since in normal SKE case, client to server connection, only
3552 the responder should do authentication. When doing SKE between
3553 two clients both should perform authentication. Updated the
3554 code and the protocol specs.
3556 * A little fix to IDENTIFY command in the server. Search the
3557 client first by hash not nickname. Affected file is
3560 * Fixed the silc_client_close_connection to support closing
3561 the client to client connections wihtout deleting too much
3562 data. Affected file lib/silcclient/client.c.
3564 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3565 are received if protocol used to be active but is not anymore
3566 the application would crash due to NULL pointer dereference.
3567 Affected files silcd/server.c and lib/silcclient/client.c.
3569 * Added `hash' field to the SilcClientConnection to include
3570 the hash function negotiated in the SKE protocol.
3572 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3573 to set the channel founder authentication data. A client can
3574 claim the founder rights later by providing the authentication
3575 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3576 This way the channel founder can regain the channel founder
3577 privileges even it is left the channel. This works only on
3578 local server and the client must be connected to the same
3579 server to be able to regain the founder rights. Updated the
3580 protocol specs accordingly.
3582 Added support to the CMODE command in the client to set the
3583 founder auth data. Read the README to see how to set it.
3585 Added support to the CUMODE command to claim the founder
3586 rights. Read the README to see how to do it.
3588 Added support for the founder authentication to the Channel
3589 Entry in the server. Affected file silcd/idlist.h.
3591 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3592 server's CMODE command. Affected file silcd/command.c.
3594 * Added the following new functions into lib/silccore/silcauth.[ch]:
3595 silc_auth_get_method and silc_auth_get_data.
3597 * The server now saves the remote hosts public key to the
3598 SilcIDListData pointer. Affected file silcd/protocol.c.
3600 * The normal server now does not remove the channel entry from
3601 the cache if the founder authentication data is set. It used
3602 to remove it if the founder was the last one on the channel on
3603 the server and left the channel. The auth data is saved and
3604 if the channel is re-joined later the old entry is used with
3605 the old auth data. Affected files silcd/command_reply.c and
3608 * Removed the `pkcs' field from the SilcIDListData structure
3609 in the server; it is not used. Affected file silcd/idlist.h.
3611 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Fixed packet processing on slow links. Partial packets were
3614 never re-processed because the incoming data buffer was cleared
3615 by the application. Application must not directly clear the
3616 sock->inbuf, the packet processing routines handle it. Fixed
3617 this in client library and in server.
3619 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Fixed the WHOIS and IDENTIFY send reply function to really
3622 check whether to send list or just one entry. Affected file
3625 * Cleaned up the LEAVE command's channel key distribution. The
3626 affected file silcd/command.c.
3628 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3629 can enforce the channel mode as well. In that case the ID
3630 includes the ID of the server. The code now enforces the
3631 mode change if the router have different mode than the server.
3633 * The notify client operation with CMODE_CHANGE notify can now
3634 return NULL client_entry pointer if the CMODE was not changed
3635 by client. Application must check for this.
3637 * Added <Server ID> argument to INFO command to support server
3638 info fetching by Server ID.
3640 * Added silc_server_announce_get_channel_users to get assembled
3641 packets of channel users of the specified channel. Affected
3642 file silcd/server.[ch].
3644 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3645 was freed underneath the ID Cache.
3647 * Re-announce clients when the server received CHANNEL_CHANGE
3648 notify from the router. Affected file silcd/packet_send.c.
3650 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3653 crashed since it did not handle the fact that there is no cipher
3654 called "3" and didn't check the error condition. Now fixed.
3656 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3657 flag. It can be used to send message requests.
3659 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Implemented the RESTART command in the client.
3663 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3664 notice type messages. Added notice printing to the user
3667 * The channel keys are not re-generated if the channel's mode
3668 is PRIVKEY, ie private key on the channel exists. Affected
3669 files silcd/server.c and silcd/command.c.
3671 * Fixed a little bug in channel message delivery when channel
3672 private keys are set in the server. Affected file is
3673 silcd/packet_send.c.
3675 * Changed the setting on channel->on_channel = TRUE from the
3676 silc_client_save_channel_key to the JOIN command reply. The
3677 key payload is not received if the private channel key is set.
3678 Affected file lib/silcclient/command_reply.c and the
3679 lib/silcclient/client_channel.c.
3681 * When the CMODE_CHANGE notify is sent and the channel private
3682 key mode is removed the channel key must be re-generated in
3683 other cells as well. Added this support for the router in the
3684 silcd/packet_receive.c.
3686 * Added new local command NOTICE to send notice message on
3687 channel. Affected file silc/local_command.[ch].
3689 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Added new local command ME to the client. It is used to send
3692 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3693 some action. Affected file silc/local_command.[ch].
3695 * Changed channel_message and private_message client operations
3696 to deliver the message flags to the application. Added also
3697 the `flags' arguments to the silc_client_send_channel_message
3698 and silc_client_send_private_message functions. Affected file
3701 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Redefined the Private Message Payload to support private message
3704 keys and to support the new private message flags. Updated
3705 the protocol specs. Flags makes it possible to have for example
3706 CTCP style messages.
3708 * Added new type SilcPrivateMessagePayload and defined an API
3709 for it in the lib/silcclient/silcprivate.[ch].
3711 * Tested private message private keys successfully. Tested the
3712 private message key set, unset and list commands with the new
3715 * Redefined the Channel Message Payload to include the channel
3716 message flags (equal with private message flags) to support
3717 for example CTCP style messages.
3719 * Defined some of the message (for channel and private message)
3720 flags. Updated the protocol specs and added the flags to the
3721 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3723 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Added SilcKeyAgreementStatus type to the key agreement routines
3726 to indicate the current status and error if one occured.
3727 The status types are defined in the lib/silcclient/silcapi.h.
3729 * Added new local command KEY that is used to set and unset private
3730 keys for channels, set and unset private keys for private messages
3731 with remote clients and to send key agreement requests and
3732 negotiate the key agreement protocol with remote client. The
3733 key agreement is supported only to negotiate private message keys,
3734 it currently cannot be used to negotiate private keys for channels,
3735 as it is not convenient for that purpose.
3737 * Fixed a minor pending callback setting bug in the function
3738 silc_client_get_client_by_id_resolve, now the function works.
3739 Affected file lib/silcclient/idlist.c.
3741 * Added function silc_net_get_local_port to get local bound
3742 port by socket. Added to lib/silcutil/silcnet.[ch].
3744 * Added `sockets' and `sockets_count' fields to the SilcClient
3745 object. They hold the sockets of the listenning sockets in
3746 the client. Listenning sockets may be for example the key
3747 agreement server. Affected file lib/silcclient/client.[ch].
3748 Added functions the silc_client_add_socket and the
3749 silc_client_del_socket. They are exported to the application
3752 * Added ~./silc/clientkeys to support other client's public keys.
3754 * Renamed verify_server_key client operation to verify_public_key
3755 and added one argument to indicate the type of the connection
3756 (server, client etc.).
3758 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Added silc_server_connection_auth_request to handle the
3761 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3762 silcd/packet_receive.[ch].
3764 * Added silc_server_send_connection_auth_request into the
3765 silcd/packet_send.c to send the connection auth request packet.
3767 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3770 * Fixed the public key authentication in responder side in the
3771 server. The `auth_data' pointer includes the SilcPublicKey
3772 not the path to the public key. Affected file silcd/protocol.c.
3774 * Implemented the public key authentication in the initiator side
3775 in the server. Affected file silcd/protocol.c.
3777 * Removed the [RedirectClient] config section from the server
3778 configuration. Is not needed and I don't want to implement it.
3780 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3782 * Cleaned up the CMODE command in the server. It now works
3783 correctly and supports all the modes defined in the protocol.
3784 Affected file is silcd/command.c.
3786 * Added `hmac_name' field to the SilcChannelEntry in the server
3787 to hold the default HMAC of the channel. It can be set when
3788 creating the channel (with JOIN command). Affected files
3791 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3792 type to indicate the change of the current cipher and hmac
3793 on the channel. Client can safely ignore the <cipher> argument
3794 (if it chooses to do so) since the CHANNEL_KEY packet will
3795 force the channel key change anyway. The <hmac> argument is
3796 important since the client is responsible of setting the new
3797 HMAC and the hmac key into use.
3799 * Fixed the CMODE command in the client library as well.
3801 * Tested CMODE command in router environment successfully.
3803 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Show the version of the remote client (or server) when connecting
3806 to the server. It is logged to the log file. Affected file
3807 is silcd/protocol.c.
3809 * Fixed the KILLED notify handling in the client library. The
3810 client must be removed from all channels when receiving the
3813 Also, do not remove the client entry when giving the KILL
3814 command but when the KILLED notify is received.
3816 * Removed silc_idlist_find_client_by_nickname from the server.
3817 Not needed anymore. Affected files silcd/idlist.[ch].
3819 * Implemented the CHANNEL_CHANGE notify type handling to the
3820 server. Affected file silcd/server.c.
3824 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Added silc_server_send_notify_invite to send the INVITE
3827 notify between routers.
3829 * Implemented the INVITE command correctly to the server.
3831 * Implemented the INVITE notify type handling in the server.
3833 * Implemented the INVITE command to the client library and on the
3836 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * Added function silc_server_get_client_resolve to find the
3839 client entry by ID from all ID lists and then resolve it
3840 (using WHOIS) if it cannot be found. Affected file is
3843 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Implemented the BAN command to the client library.
3847 * The JOIN command in the server now checks the invite list
3850 * Changed the silc_command_reply_payload_encode_va and the
3851 silc_command_payload_encode_va to support that if argument is
3852 NULL it ignores and checks the next argument. Affected file
3853 lib/silccore/silccommand.c.
3855 * Added silc_server_send_notify_ban to send the BAN notify
3856 type between routers.
3858 * Chaned the silc_notify_payload_encode to support that if
3859 argument is NULL it ignores and checks the next argument.
3860 Affected file lib/silccore/silcnotify.c.
3862 * Tested ban lists in router environment successfully.
3864 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Implemented BAN command to the server, in silcd/command.[ch].
3868 * Removed the BAN and INVITE_LIST modes from the CMODE command
3871 * Added function silc_string_match to regex match two strings.
3872 Affected files lib/silcutil/silcutil.[ch].
3874 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Redefined parts of the SilcChannelEntry in the server to support
3877 the new ban and invite lists.
3879 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Redefined the INVITE command. The same command can be used to
3882 invite individuals to the channel but also to manage the invite
3883 list of the channel (to add to and remove from the invite list).
3884 Updated the protocol specs.
3886 * Added new command SILC_COMMAND_BAN that can be used to manage
3887 the ban list of the channel. Updated the protocol specs.
3889 * Removed the channel modes: the SILC_CMODE_BAN and the
3890 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3891 in the CMODE command. The equivalent features are now available
3892 using INVITE and BAN commands. Updated the protocol specs.
3894 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3895 in the network about change in the current ban list. The notify
3896 type is not used by the client.
3898 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3899 support the invite lists.
3901 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Added new function silc_string_regexify that converts string
3904 including wildcard characters into regex string that can
3905 be used by the GNU regex library. Added into the file
3906 lib/silcutil/silcutil.[ch].
3908 Added silc_string_regex_combine to combine to regex strings
3909 into one so that they can be used as one regex string by
3910 the GNU regex library. Added into the file
3911 lib/silcutil/silcutil.[ch].
3913 Added silc_string_regex_match to match two strings. It returns
3914 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3916 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Imported GNU regex to the soruce tree into lib/contrib.
3919 Fixed some compiler warning from the regex.c.
3921 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Fixed MOTD command in the server to work in router environment.
3925 * Fixed the MOTD command in the client library to support
3926 the server argument in the command.
3928 * Added `nickname_len' argument to the silc_idlist_add_client
3929 in the server, as the `nickname' argument may be binary data
3932 * Added silc_idlist_get_channels to return all channels from
3935 * Implemented LIST command to the server. Affected file is
3938 * Implemented the LIST command to the client library and on the
3941 * Added [<user count>] argument to the LIST command reply.
3942 With private channels the user count is not shown.
3944 * Updated TODO and README.
3946 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * The client entry's data.registered must be TRUE even with
3949 global client entry on global client list. The data.registered
3950 is used to check whether the client is anymore in the network,
3951 for example with WHOWAS command so it must be valid.
3953 * Fixed the WHOWAS command in the server. It now actually works
3954 in router environment. Added function into silcd/command_reply.c
3955 silc_server_command_reply_whowas_save.
3957 * Added silc_idlist_purge function to the silcd/idlist.c
3958 to periodically purge the ID Cache.
3960 * Fixed INFO command in the server. It works now in router
3961 environment. Added <server name> argument to the INFO command
3962 reply. Updated the protocol specs.
3964 * Fixed minor bug in silc_idcache_purge to not purge if the
3965 expire value is zero.
3967 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3968 they were buggy because of the WHOWAS information.
3970 * Fixed local command MSG to handle the async resolving of
3971 the remote client properly. It used to fail the first MSG.
3972 Affected file silc/local_command.c.
3974 * Added `data_len' field to SilcIDCache context.
3976 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Update TODO. Todo in commands in the server.
3980 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3983 used by routers as broadcast packet to inform other routers
3984 about the changed user mode.
3986 Implemented the notify handling in the server. Affected file is
3987 silcd/packet_receive.c. Added the function
3988 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3990 * Added new generic Channel Payload and deprecated the New Channel
3991 Payload. The New Channel Payload is now the generic Channel
3994 * Added new argument `mode' to the silc_server_send_new_channel
3995 as it is required in the Channel Payload now.
3997 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3998 and created a new and real SilChannelPayload to represent the
3999 new generic Channel Payload. Implemented the encode/decode
4000 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4002 * Added silc_server_get_client_channel_list to return the list
4003 of channels the client has joined for WHOIS command reply.
4004 Affected file silcd/server.[ch].
4006 * Implemented the channel list sending in the WHOIS command reply
4007 in server and in the client.
4009 Implemented the channel list displaying on the user interface
4010 as well. Affected file silc/client_ops.c.
4012 * Added silc_channel_payload_parse_list to parse list of Channel
4013 Payloads. It returns SilcDList list of SilcChannelPayloads.
4014 Client for example can use this function to parse the list of
4015 channels it receives in the WHOIS command reply. The caller
4016 must free the list by calling silc_channel_payload_list_free.
4017 Affected files lib/silccore/silcchannel.[ch].
4019 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Added one new argument <user mode> to the WHOIS command reply
4022 to return the mode of the user in SILC. Updated the protocol
4025 Implemented it to the server and client.
4027 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Fixed the mode printing on the user interface on joining.
4030 Affected file silc/client_ops.c.
4032 * Implemented the UMODE command and user modes in general to the
4033 client library and to the user interface.
4035 * Implemented the UMODE command to the server.
4037 * The server now sends UNKNOWN_COMMAND error status if client sends
4038 unknown command. Affected file silcd/command.c.
4040 * All server commands now handle the command identifier the right
4041 way when sending the command reply to the client. The client can
4042 use to identify the command replies with the identifier.
4044 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Added silc_server_get_client_route to resolve the route to
4047 the client indicated by the client ID. Affected file is
4050 * Added silc_server_relay_packet as general function to relay
4051 packet to arbitrary destination. This deprecates functions
4052 like _send_private_message_key, _relay_notify etc. Affected
4053 file is silcd/packet_send.[ch].
4055 Removed silc_server_send_key_agreement,
4056 silc_server_send_private_message_key and
4057 silc_server_packet_relay_notify functions from the file
4058 silcd/packet_send.[ch].
4062 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4063 server. Affected file silcd/packet_receive.[ch].
4065 * Implemented the KILL command to the client. Implemented the
4066 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4067 Affected files lib/silcclient/command[_reply].c and
4068 lib/silcclient/client_notify.c. Implemented the KILL notify
4069 printing in the user inteface.
4071 * Fixed a lot silc_parse_nick memory leaks from the client
4072 library in the file lib/silcclient/command.c.
4074 * Changed the silc_server_send_notify_on_channels's `sender'
4075 argument from SilcSocketConnection to SilcClientEntry to
4076 check the sender as entry and not as connection object and not
4077 to send to the client provided as argument. The affected file
4078 is silcd/packet_send.[ch].
4080 * The notify packets that are destined directly to the client used
4081 to not to be processed by the server. Now changed that and the
4082 server processes all notify packets. After relaying the packet
4083 to the client the notify packet is processed in the server.
4085 * The silc_server_free_client_data now checks whether there is
4086 pending outgoing traffic for the client and purges the data to
4087 the network before removing the client entry.
4089 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4092 an client is killed from the SILC Network. Updated the protocol
4095 Added new function silc_server_send_notify_killed to the
4096 silcd/packet_send.[ch].
4098 * Added function silc_server_packet_relay_notify to relay notify
4099 packets that are destined directly to a client. In this case
4100 the server does not process the notify packets but merely relays
4101 it to the client. Affected file silcd/packet_send.[ch].
4103 Added also silc_server_packet_process_relay_notify to check
4104 whereto relay the notify. Affected file is
4105 silcd/packet_receive.[ch].
4107 * Implemented the KILL command to the server.
4111 * Added the backup schema desgined last fall to the protocol
4112 specs for everyone to see. The specification is in the
4113 *-spec-xx.txt draft and the packet type definitions for the
4114 backup routers is in *-pp-xx.txt draft. Thusly, added also
4115 new packet type SILC_PACKET_CELL_ROUTERS.
4117 * A big security problem in the implementation discovered. The
4118 signoff of an client did not cause new channel key generation
4119 which it of course should've done. The channel keys must be
4120 always re-generated when client leaves (or signoffs) the channel.
4121 The silc_server_remove_from_channels funtion now handles
4122 the channel key re-generation.
4124 * Added `sender' argument to the silc_server_send_notify_on_channels
4125 to not to send the client provided as argument. Affected file
4126 silcd/packet_send.[ch].
4128 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Implemented OPER and SILCOPER commands into the server and
4133 * Added silc_auth_verify and silc_auth_verify_data to verify
4134 the authentication directly from the authentication payload.
4135 It supports verifying both passphrase and public key based
4136 authentication. Affected file lib/silccore/silcauth.[ch].
4138 * Added `hash' field to the SilcIDListData structure. It is the
4139 hash negotiated in the SKE protocol. Affected file is
4142 * Slight redesigning of the SilcAuthPayload handling routines.
4143 Do not send SilcPKCS but SilcPublicKey as argument.
4145 * Implemented the public key authentication support to the
4146 serverconfig. The public key is loaded from the provided path
4147 and saved as authentication data to void * pointer. Thus,
4148 changed the unsigned char *auth_data to void *auth_data;
4150 * Fixed SHUTDOWN command to send the reply before the server
4151 is shutdown. :) Affected file silcd/command.c.
4153 * Fixed fatal bug in CONNECT command. The hostname was invalid
4154 memory and server crashed. Affected file silcd/command.c.
4156 * Fixed fatal bug in CLOSE command. The server_entry became
4157 invalid but was referenced later in the command. Affected file
4160 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Fixed fatal bug in failure packet handling. Server ignored
4163 the failure and thus crashed when it came.
4167 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4170 that the command may be executed only once in (about) 2 seconds.
4171 The old SILC_CF_LAG flag is same but allows command bursts up
4172 to five before limiting.
4174 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4175 server code. Various commands now includes the CF_LAG_STRICT
4176 flag to disallow any kind of miss-use of the command.
4178 * Fixed the silc_buffer_unformat to not to allocate any data
4179 if the length of the data is zero. It used to allocate the
4180 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4182 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Changed the format of AdminConnection configuration section
4185 in the server. Added username of the admin to the format.
4186 Affected files silcd/serverconfig.[ch].
4188 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4189 to return admin configuration data by host, username and/or
4192 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Implemented WHOWAS command to the server. Added the functions:
4196 silc_server_command_whowas_parse,
4197 silc_server_command_whowas_send_reply,
4198 silc_server_command_whowas_from_client and
4199 silc_server_command_whowas_from_server
4201 * Added <Client ID> argument to the WHOWAS command reply. Updated
4202 the protocol specs accordingly.
4204 * Implemented WHOWAS command and command_reply to the client
4207 Implemented the WHOWAS printing on the user interface.
4209 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Added new argument to the WHOWAS command reply, the real name.
4212 It is an optional argument. Updated the protocol specs.
4214 * Added SilcIDCacheDestructor callback that is registered when
4215 the SilcIDCache is allocated. The callback is called when
4216 an cache entry in the ID Cache expires, or is purged from the
4217 cache. Added into lib/silccore/idcache.[ch].
4219 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4220 to destruct the client entries when the cache entry expires.
4221 Other ID Cache's in server and in the client library ignores
4224 * If the ID Cache entry's `expire' field is zero then the entry
4225 never expires. Added boolean `expire' argument to the
4226 silc_idcache_add function in the lib/silccore/idcache.[ch].
4227 If it is TRUE the default expiry value is used.
4229 * Added silc_server_free_client_data_timeout that is registered
4230 when client disconnects. By default for 5 minutes we preserve
4231 the client entry for history - for WHOWAS command.
4233 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Added support to the server to enforce that commands are not
4236 executed more than once in 2 seconds. If server receives
4237 commands from client more frequently, timeout is registered
4238 to process the commands. Affected file silcd/command.c.
4239 Added new function silc_server_command_process_timeout.
4241 * Changed NICK_NOTIFY handling in client library to check that
4242 if the client's nickname was changed, so there is no need to
4243 resolve anything from the server.
4245 * Removed error printing from the WHOIS and IDENTIFY commands.
4246 If error occurs then it is ignored silently in the client library.
4247 The application, however, may map the received error to
4248 human readable error string. The application currently maps
4249 the NO_SUCH_NICKNAME error to string.
4251 * Made the command status message public to the application. Moved
4252 them from lib/silcclient/command_reply.c to
4253 lib/silcclient/command_reply.h. The application can map the
4254 received command status to the string with the
4255 silc_client_command_status_message function.
4257 * Added check to the server to check that client's ID is same
4258 as the Source ID in the packet the client sent. They must
4261 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added dist-bzip hook to the Makefile.am to make bzip2
4264 compressed distributions.
4266 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Server now enforces the maximum length for the nickname and
4269 the channel as protocol specification dictates. 128 bytes for
4270 nickname and 256 bytes for channel name.
4272 * Moved the WHOIS printing to the application. The client libary
4273 does not print out the WHOIS information anymore, the application
4274 must do it. Renamed silc_client_command_reply_whois_print to
4275 the silc_client_command_reply_whois_save.
4277 The client's idle time is also sent to the application now, and
4278 the idle is shown on screen.
4280 * Added silc_client_command_reply_identify_save to save the
4281 received IDENTIFY entries.
4283 * Do not check for channel private keys in message sending and
4284 reception if the channel does not have the PRIVKEY mode set.
4285 Affected file lib/silclient/client_channel.c.
4287 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4290 just surfaced after chaning the JOIN procedure.
4292 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Added silc_client_get_clients_by_list to get client entries
4295 from Client ID list, that is returned for example by JOIN
4296 and USERS command replies. The application should use this
4297 function for example when JOIN command reply is received to
4298 resolve the clients already on the channel (library does not
4299 do that anymore as USERS command reply is not used in the JOIN
4300 procedure anymore). Affected files lib/silcclient/silcapi.h and
4301 lib/silcclient/idlist.c.
4303 * JOIN command reply and USERS command reply returns now SilcBuffer
4304 pointers instead of unsigned char pointers when returning
4305 the client list and mode list.
4307 * Added <Client ID> argument to the JOIN command reply, mainly
4308 for the server to identify for which client the command was
4309 originally sent. Updated protocol specs accordingly.
4311 * Added SilcDlist private_key pointer to the SilcChannelEntry
4312 in the client to support the channel private keys. Affected
4313 file is lib/silcclient/idlist.h.
4315 * Added SilcChannelPrivateKey argument to the function
4316 silc_client_send_channel_message so that application can choose
4317 to use specific private ke if it wants to. If it is not provided,
4318 the normal channel key is used, unless private keys are set.
4319 In this case the first (key that was added first) is used
4320 as the encryption key.
4322 * Implemented the support for channel private key handling.
4323 Implemented the following functions:
4325 silc_client_add_channel_private_key,
4326 silc_client_del_channel_private_keys,
4327 silc_client_del_channel_private_key,
4328 silc_client_list_channel_private_keys and
4329 silc_client_free_channel_private_keys
4331 Affected file lib/silcclient/client_channel.c.
4333 * Added the support for the private keys in the channel message
4334 sending and encryption and in the message reception and
4335 decryption. Affected funtions are
4336 silc_client_send_channel_message and silc_client_channel_message.
4338 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Added SKE's key verify callback to the client library's
4341 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4343 * Removed the statement that server (or router) must send USERS
4344 command reply when joining to the channel so that the client
4345 knows who are on the channel. Instead, the client list and
4346 client's mode list is now sent in the JOIN command reply to the
4347 client who joined channel. This is better solution.
4349 * Added function silc_server_get_users_on_channel and function
4350 silc_server_save_users_on_channel to the silcd/server.[ch].
4352 * Removed function silc_server_command_send_users from the
4355 * Do not show topic on the client library anymore. The topic is
4356 sent in the command reply notify to the application and the
4357 application must show the topic now.
4359 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4361 * Added client searching by nickname hash into the IDENTIFY and
4362 WHOIS commands in the server as they were clearly missing from
4363 them. Affected file is silcd/command.c.
4365 * Fixed a bug in private message receiving in the client library.
4366 The remote ID was freed and it wasn't supposed, now it is
4369 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Minor fix to the channel payload; allocate the data area, as it
4372 needs to be of specific length.
4374 * If the key agreement port is zero then the operating
4375 system will define the bound port. Affected files are
4376 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4378 * Added new function silc_channel_payload_decrypt into the file
4379 lib/silccore/silcchannel.[ch].
4381 * Moved the channel message etc, check from silc_packet_decrypt
4382 to applications. The library calls now a generic
4383 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4384 when the packet is either normal or special. This was done to
4385 allow more wide range of checking that was not allowed when
4386 the code was in library. Now applications can do virtually any
4387 checks to the packet and return to the library the decision how
4388 the packet should be processed. Affected files are
4389 lib/silccore/silcpacket.[ch].
4391 Added silc_server_packet_decrypt_check to the server and
4392 silc_client_packet_decrypt_check to the client library.
4394 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4395 to send with specified source and destination information.
4397 * Channel message delivery between routers was broken after the
4398 channel key distribution was fixed earlier. The channel key
4399 was used be to distributed to other routers as well which is not
4400 allowed by the protocol. Now this is fixed and channel keys
4401 really are cell specific and the channel message delivery between
4402 routers comply with the protocol specification.
4404 * Fixed various commands in server to check also the global list
4405 for the channel entry and not just the local list. The affected
4406 file silcd/command.c.
4408 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Added assert()s to buffer formatting and unformatting routines
4411 to assert (if --enable-debug) when error occurs. Affected
4412 file: lib/silcutil/silcbuffmt.c.
4414 * Changed to auto-reconnect to check whether the remote host is
4415 router and register the re-connect timeout if it is. It used
4416 to check that whether we are normal server, but router must do
4417 auto-reconnect with another router as well. Affected file
4420 * Removed the [<key len>] option from CMODE command as the cipher
4421 name decides the key length, nowadays. See the defined ciphers
4422 from the protocol specification.
4424 * Added [<hmac>] option to the CMODE command to define the HMAC
4425 for the channel. Added SILC_CMODE_HMAC channel mode.
4427 * Added [<hmac>] option for the JOIN command so that user can
4428 select which HMAC is used to compute the MACs of the channel
4431 * Added Hmac field to the Channel Message Payload. The integrity
4432 of plaintext channel messages are now protected by computing
4433 MAC of the message and attaching the MAC to the payload. The
4434 MAC is encrypted. Now, it is clear that this causes some
4435 overhead to the size of the packet but rationale for this is that
4436 now the receiver can verify whether the channel message decrypted
4437 correctly and also when private keys are set for the channel the
4438 receiver can decrypt the packet with several keys and check from
4439 the MAC which key decrypted the message correctly.
4441 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4442 lib/silccrypt/silccipher.[ch].
4444 * Added silc_hash_len to return the digest length into the
4445 lib/silcrypt/silchash.[ch].
4447 * Rewrote parts of Silc Channel Payload interface in the
4448 lib/silccore/silcchannel.[ch]. The encode function now also
4449 encrypts the packet and parse function decrypts it.
4451 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Fixed a minor formatting bug in the SKE's key material processing.
4454 It actually might have processed the keys wrong way resulting
4457 * Redefined the mandatory HMAC algorithms and added new algorithms.
4458 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4459 and hmac-md5 truncated to 96 bits. The mandatory is now
4460 hmac-sha1-96. Rest are optional (including the one that used
4461 to be mandatory). Rationale for this is that the truncated HMAC
4462 length is sufficient from security point of view and can actually
4463 make the attack against the HMAC harder. Also, the truncated
4464 HMAC causes less overhead to the packets. See the RFC2104 for
4467 * Added new [hmac] configuration section. The SKE used to use
4468 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4469 is of course wrong. The official names that must be proposed in
4470 the SKE are the ones defined in the protocol specification
4471 (hmac-sha1-96 for example). The user can configure any hmac
4472 using any hash function configured in the [hash] section. At
4473 least, the mandatory must be configured.
4475 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4477 * Added HMAC list to the SKE proposal list. It has now both
4478 hash algorithm list and HMAC list. This makes the protocol
4479 incompatible with previous versions. The SKE now seems to work
4480 the way it is supposed to work, for the first time actually.
4482 * Defined plain Hash algorithms to the protocol specification.
4485 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Implemented support for key agreement packets into the server.
4488 Added functions silc_server_key_agreement and
4489 silc_server_send_key_agreement. Other than these functions,
4490 server has nothing to do with this packet.
4492 * Added support for private message key packets into the server.
4493 Added functions silc_server_private_message_key and
4494 silc_server_send_private_message_key.
4498 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4499 called in the protocol's final callback instead in the END
4500 protocol state. This makes a little more sense and in the same
4501 time in client we can use the same protocol routines for normal
4502 key exchange and to key agreement packet handling as well.
4504 * Added to both client's and server's KE protocol context the
4505 SilcSKEKeyMaterial pointer to save the key material. We will
4506 bring the key material to the protocol's final callback by doing
4507 this. The final callback must free the key material.
4509 * Added SKE's packet_send callback into client's KE protocol
4510 context so that the caller can choose what packet sending function
4511 is used. This way we can use different packet sending when
4512 doing normal SKE when doing key agreement packet handling (in
4513 the key agreement packet handling we do not want to encrypt
4516 * Implemented the responder side of the key agreement routines
4517 in the client. The client can now bind to specified port and
4518 accept incoming key negotiation. The key material is passed
4519 to the application after the protocol is over.
4521 * Implemented the processing of incoming Key Agreement packet
4522 in the client. Added function silc_client_key_agreement to
4525 * Implemented the intiator side of the key agreement routines
4526 in the client. The client can now initiate key agreement with
4527 another remote client. The key material is passed to the
4528 application after the protocol is over.
4530 * Created client_keyagr.c to include all the key agreement
4533 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4534 SILC_TASK_CALLBACK except that it is not static.
4536 * Created client_notify.c and moved the Notify packet handling
4537 from the client.[ch] into that file.
4539 * Created client_prvmsg.c and moved all private message and
4540 private message key routines from the client.[ch] into that file.
4542 * Create client_channel.c and moved all channel message and
4543 channel private key routines from the client.[ch] into that file.
4545 * Changed silc_client_get_client_by_id_resolve to resolve with
4546 WHOIS command instead of IDENTIFY command, in the file
4547 lib/silclient/idlist.c.
4549 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Implemented the SKE's responder side to the Client library.
4553 * When FAILURE is received to the protocol do not trust it
4554 blindly. Register a timeout to wait whether the remote closes
4555 the connection as it should do it, only after that process the
4556 actual failure. This was changed to both client and server.
4558 * Added client_internal.h to include some of the structures
4559 there instead of client.h in lib/silcclient/.
4561 * Added function silc_task_unregister_by_callback to unregister
4562 timeouts by the callback function.
4564 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Some "Incomplete WHOIS info" errors has been appearing on the
4567 log files. Took away the entry->userinfo check from WHOIS
4568 reply sending. The entry->userinfo is now " " if client did not
4569 provide one. I thought this was fixed earlier but something
4570 is wrong still. Let's see if the error still appears.
4572 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Fixed a minor bug in the login when the channel key is
4575 re-generated in the server. It used to generate the key in
4576 wrong order and thus caused problems in the channel traffic.
4578 * Fixed a minor bug in channel key distsribution after
4579 KICK command. The key was not sent to the router even though
4582 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Added silc_ske_process_key_material_data as generic routine
4585 to process any key material as the SILC protocol dictates. The
4586 function is used by the actual SKE library but can be used by
4587 applications as well. This relates to the private message keys
4588 and the channel private keys since they must be processed the
4589 same way the normal SILC session keys. The protocol dictates
4590 this. Affected files: lib/silcske/silcske.[ch].
4592 Added also silc_ske_free_key_material to free the
4593 SilcSKEKeyMaterial structure.
4595 * Defined silc_cipher_set_key function to set the key for
4596 cipher without using the object's method function. The affected
4597 files: lib/silccrypt/silccipher.[ch].
4599 * Implemented silc silc_client_add_private_message_key,
4600 silc_client_add_private_message_key_ske,
4601 silc_client_del_private_message_key,
4602 silc_client_list_private_message_keys and
4603 silc_client_free_private_message_keys functions in the
4606 Added functions silc_client_send_private_message_key to send
4607 the Private Message Key payload and silc_client_private_message_key
4608 to handle incoming Private Message Key payload.
4610 * Added Cipher field to the Private Message Key payload to set
4611 the cipher to be used. If ignored, the default cipher defined
4612 in the SILC protocol (aes-256-cbc) is used.
4614 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Removed lib/silcclient/ops.h file.
4618 Redefined parts of the SILC Client Library API. Created new
4619 file silcapi.h that deprecates the ops.h file and defines the
4620 published Client Library API. Defined also private message key
4621 API and channel private key API into the file.
4623 This is the file that the application must include from the
4624 SILC Client Library. Other files need not be included by
4625 the application anymore.
4627 * Added new key_agreement client operation callback and also
4628 defined the Key Agreement library API for the application.
4630 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4633 is used by clients to request key negotiation between another
4634 client in the SILC network. If the negotiation is started it
4635 is performed using the SKE protocol. The result of the
4636 negotiation, the secret key material, can be used for example
4637 as private message key.
4639 Implemented the Key Agreement payload into the files
4640 lib/silccore/silauth.[ch].
4642 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4644 * Redefined ciphers for the SILC protocol. Added some new ciphers
4645 and defined the key lengths for the algorithms. Changed the
4646 code accordingly. The default key length is now 256 bits.
4648 * Fixed SKE key distribution function silc_ske_process_key_material
4649 when the key length is more than 128 bits. The default key
4650 length in SILC is now 256 bits.
4652 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4653 to indicate unsupported algorithm.
4655 * Renamed rijndael.c to aes.c and all functions as well.
4657 * Fixed a long standing channel key setting bug in client library.
4658 Weird that it has never surfaced before.
4660 * Fixed bug in channel deletion. If the entire channel is removed
4661 then it must also delete the references of the channel entry
4662 from the client's channel list as the client's channel entry and
4663 the channel's client entry share same memory.
4665 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Implemented CONNECT and SHUTDOWN commands in the client.
4669 * Implemented CLOSE command to the client.
4671 * Added the function silc_idlist_find_server_by_name into the
4672 files silcd/idlist.[ch].
4674 Added the function silc_idlist_find_server_by_conn into the
4675 files silcd/idlist.[ch].
4677 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * DIE command was renamed to SHUTDOWN. Updated the both code
4682 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4683 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4685 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4688 * Added function silc_server_create_connection function to create
4689 connection to remote router. My server implementation actually
4690 does not allow router to connect to normal server (it expects
4691 that normal server always initiates the connection to the router)
4692 so the CONNECT command is only good for connecting to another
4695 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4698 or some other client was kicked from the channel.
4700 Implemented the handling of the notify type to both client
4703 Implemented silc_server_send_notify_kicked to send the KICKED
4704 notify. It is used to send it to the server's primary router.
4706 * Implemented the KICK command into server and client.
4708 * Added `query' argument to the silc_idlist_get_client function
4709 to indicate whether to query the client from server or not if
4712 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4713 to indicate that the client is not channel founder.
4717 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Removed the rng context from SilcPacketContext structure and
4720 changed that the packet routine uses the Global RNG API.
4722 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Added support for quit message that client can "leave" on the
4725 channel when it quits the SILC. It is ditributed inside the
4726 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4728 Added silc_server_free_client_data that will take the
4729 signoff message as argument.
4731 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4733 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Updated parts of the protocol specification to keep it up
4738 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4741 payloads in one packet.
4743 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4744 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4745 use now the new List flag.
4747 * Also deprecated the following packet types: REPLACE_ID,
4748 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4750 * Added list support for Notify packet in server.
4752 * Added silc_server_send_notify_channel_change to send the
4753 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4754 the silc_server_send_replace_id.
4756 * Added silc_server_send_notify_nick_change to send the
4757 NICK_CHANGE notify type. Deprecates the function
4758 silc_server_send_replace_id.
4760 * Added silc_server_send_notify_join to send the JOIN notify type.
4761 Deprecates the function silc_server_send_new_channel_user.
4763 * Added silc_server_send_notify_leave to send LEAVE notify type.
4764 Deprecates the function silc_server_send_remove_channel_user.
4766 * Added silc_server_send_notify_cmode and
4767 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4768 types. Deprecates the silc_server_send_set_mode function.
4770 * Added SERVER_SIGNOFF notify type to indicate that server has
4771 quit. This means that all clients on the channel from that
4772 server will drop. This can be also used when netsplit happens.
4774 Deprecated REMOVE_ID packet type since it is not needed anymore
4777 Added silc_server_send_notify_server_signoff to send the
4778 SERVER_SIGNOFF notify type. Deprecates the function
4779 silc_server_send_remove_id.
4781 Added also silc_server_send_notify_signoff to send the
4782 SIGNOFF notify type.
4784 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4785 SILC protocol from this day on. Changed the protocol
4786 specification as well.
4788 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4789 notify type. It is used between routers to notify about
4790 topic changes on a channel.
4792 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4795 * Partly updated the protocol specification to comply with the
4796 changes now made. It is still though a bit outdated.
4798 * The JOIN notify type now takes one extra argument <Channel ID>.
4799 The packet used to be destined to the channel but now the
4800 JOIN type may be sent as list thus it is impossible to
4801 destine it to any specific channel. By adding this argument
4802 it is again possible.
4804 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Added CREDITS file. The CHANGES and CREDITS file will appear
4807 in the distribution as well.
4809 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4812 types in the server's silcd/packet_receive.c.
4814 * Implemented CMODE and CUMODE to work in router environment.
4816 * Fixed minor encoding and decoding buglet from the
4817 lib/silccore/silcmode.c.
4819 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4822 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4824 * Changed all SilcConfigServer* and silc_config_server* to
4825 SilcServerConfig* and silc_server_config*, respectively.
4828 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Associated the ID (client or server ID) to the Authentication
4831 Payload to avoid any possibility of forging. Updated the
4832 protocol specification and the code accordingly.
4834 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * The RSA key length is now save to the RsaKey context in the
4837 key generation process in lib/silccrypt/rsa.c. The key length
4838 is now used to figure out the maximum size of the block allowed
4839 to be encrypted/signed.
4841 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4842 is equivalent to the silc_mp_mp2bin but does not allocate any
4845 * Changed silc_mp_mp2bin API to take length argument. If it is
4846 non-zero then the buffer is allocated that large. If zero, then
4847 the size is approximated using silc_mp_sizeinbase, which however
4850 * Created Global RNG API which is global RNG that application can
4851 initialize. After initializing, any routine anywhere in the
4852 code (including library) can use RNG without allocating a new
4853 RNG object. This was done to allow this sort of use of the
4854 RNG in code that has no chance to allocate RNG object. All
4855 applications currently allocate this and many routines in the
4856 library use this. Affected file lib/silccrypt/silcrng.[ch].
4858 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4859 it to use the Global RNG API.
4861 * Defined Authentication Payload into protocol specification that
4862 is used during SILC session to authenticate entities. It is
4863 used for example by client to authenticate itself to the server
4864 to obtain server operator privileges.
4866 Implemented this payload into the lib/silccore/silcauth.[ch].
4867 Implemented also routines for public key based authentication
4868 as the new protocol specification dictates.
4870 Moved definitions of different authentication methods from
4871 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4873 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4874 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4875 silc_pkcs_verify_with_hash functions into the file
4876 lib/silccrypt/silcpkcs.[ch].
4878 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * The client entry's userinfo pointer must be always valid.
4881 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4882 will fail since it requires the userinfo. Now, the userinfo
4883 is allocated as "" if actual userinfo does not exist. Actually,
4884 it must exist and it is totally Ok to drop client connections
4885 that does not announce the userinfo. However, we will make
4886 this workaround for now.
4888 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4889 to return the remote port by socket.
4891 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4894 SILC_SERVER_PENDING_EXEC and added an new macro
4895 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4896 data or when error occurs while processing the pending command.
4898 Added new argument `destructor' into silc_server_command_pending
4899 and to the SilcServerCommandPending object. This destructor is
4900 now called after calling the pending callback or if error occurs
4901 immediately. If error occurs the actual pending callback won't
4902 be called at all - only the destructor. The destructor may be
4903 NULL if destructor is not needed.
4905 All this applies for client library code as well. Similar
4906 changes were made there as well for the pending commands.
4908 In the client, the application must now allocate the
4909 SilcClientCommandContext with the silc_client_command_alloc
4912 * Added reference counter to the SilcServerCommandContext. Added
4913 function silc_server_command_alloc and silc_server_command_dup
4916 Same type of functions added to the client library for the same
4919 * Removed the cmd_ident from IDListData away since it is now
4920 global for all connections. It is the command identifier used
4921 in command sending and with pending commands. The affected file
4924 * Added reference counter to the SilcSocketConnection objecet to
4925 indicate the usage count of the object. The object won't be
4926 freed untill the reference counter hits zero. Currently only
4927 server uses this, and client ignores it. The client must be
4928 set to use this too later. The affected files are
4929 lib/silccore/silcsockconn.[ch]. Added also the function
4930 silc_socket_dup to increase the reference counter.
4932 This was mainly added because it is possible that the socket
4933 is removed underneath of pending command or other async
4934 operation. Now it won't be free'd and proper DISCONNECTING
4935 flags, etc. can be set to avoid sending data to connection that
4936 is not valid anymore.
4938 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4939 the connection. After that it sets SILC_SET_DISCONNECTED.
4940 It is, however, possible that the socket data is not still freed.
4941 The silc_server_packet_process now checks that data is not
4942 read or written to connection that is DISCONNECTED. The socket
4943 get's freed when the reference counter hits zero.
4945 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Changed the client operation API: channel_message operation's
4948 `sender' is now the client entry of the sender, not the nickname
4949 and the `channel' is the channel entry, not the channel name.
4951 In the private_message operation the `sender' is now also the
4952 client entry of the sender not the nickname.
4954 Affected file is lib/silcclient/ops.h and all applications
4955 using the client operations.
4957 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Moved the calling of ops->connect() from connect_to_server_final
4960 into receive_new_id functin since that is the point when the
4961 client is actually allowed to send traffic to network. The
4962 affected file is lib/silcclient/client.c.
4964 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4967 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4968 (if needs broadcasting) instead of broadcasting the packets one
4969 by one which would make a burst in the network traffic.
4971 * Added `broadcast' argument to the functions in silcd/server.[ch]
4972 silc_server_create_new_channel[_with_id] to indicate whether
4973 to send New Channel packet to primary router.
4975 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Added new function into the silcd/server.[ch] files:
4978 silc_server_create_new_channel_with_id to create new channel with
4979 already existing Channel ID.
4981 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4982 lib/silccore/silcpacket.h. This packet is used t send list of
4983 Set Mode payloads inside one packet. Server uses this to set
4984 the modes for the channels and clients on those channels, that it
4985 announced to the router when it connected to it. The protocol
4986 specification has been updated accordingly.
4988 * The silc_server_new_channel did not handle the packet coming
4989 from normal server as it normally does not send that. However,
4990 when it announces its channels it does send it. Implemented
4991 the support for that.
4993 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4994 into the file lib/silccore/id.h.
4996 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Fixed memory leaks in the functions silc_idlist_del_client,
4999 silc_idlist_del_channel and silc_idlist_del_server in the file
5000 silcd/idlist.c. All of those leaked like a sieve.
5002 * Fixed some small memory leaks in the client's function
5003 silc_client_notify_by_server.
5005 * Added functions into silcd/server.c: silc_server_announce_clients,
5006 silc_server_announce_channels and silc_server_announce_server.
5007 These functions are used by normal and router server to announce
5008 to its primary router about clients, channels and servers (when
5009 router) that we own. This is done after we've connected to the
5012 These functions effectively implements the following packet types:
5013 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5014 and SILC_PACKET_NEW_ID_LIST.
5016 * Added new functions into the silcd/packet_receive.[ch]:
5017 silc_server_new_id_list, silc_server_new_channel_list and
5018 silc_server_new_channel_user_list to handle the incoming
5019 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5021 * Added support of changing Channel ID in the function
5022 silc_server_replace_id. If the server that announces a channel
5023 to the router already exists in the router (with same name but
5024 with different Channel ID), router is responsible to send
5025 Replace ID packet to the server and force the server to change
5026 the Channel ID to the one router has.
5028 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5029 client that the Channel ID has been changed by the router. The
5030 normal server sends this to the client. Client must start using
5031 the new Channel ID as the channel's ID.
5033 Implemented handling of this new type into lib/silcclient/client.c
5034 into the function silc_client_notify_by_server.
5036 * Added new function silc_idlist_replace_channel_id into the files
5037 silcd/idlist.[ch] to replace the Channel ID.
5039 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Call silc_server_command_identify_check always when processing
5042 the IDENTIFY command in silcd/command.c
5044 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5047 send keepalive packets. The packet can be sent by clients,
5048 servers and routers.
5050 Added function silc_socket_set_heartbeat into the file
5051 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5052 If not set, the heartbeat is not performed. The actual
5053 heartbeat is implemented in the low level socket connection
5054 library. However, application is responsible of actually
5057 Added silc_server_send_heartbeat to send the actual heartbeat
5058 packet into silcd/packet_send.[ch]. Server now performs
5059 keepalive with all connections.
5061 * Added silc_task_get_first function into lib/silcutil/silctask.c
5062 to return the timeout task with shortest timeout. There was a bug
5063 in task unregistration that caused problems. TODO has been
5064 updated to include that task system must be rewritten.
5066 * The client library will now resolve the client information when
5067 receiving JOIN notify from server for client that we know but
5068 have incomplete information.
5070 * Rewrote parts of silc_server_remove_from_channels and
5071 silc_server_remove_from_one_channel as they did not remove the
5072 channel in some circumstances even though they should've.
5074 * Encryption problem encountered in server:
5076 The LEAVE command used to send the Channel Key packet to the
5077 router immediately after generating it. However, the code
5078 had earlier sent Remove Channel user packet but not immediately,
5079 ie. it was put to queue. The order of packets in the router
5080 was that Channel Key packet was first and Remove Channel User
5081 packet was second, even though they were encrypted in the
5082 reverse order. For this reason, MAC check failed. Now, this
5083 is fixed by not sending the Channel Key packet immediately but
5084 putting it to queue. However, this is more fundamental problem:
5085 packets that are in queue should actually not be encrypted
5086 because packets that are sent immediately gets encrypted
5087 actually with wrong IV (and thus MAC check fails). So, packets
5088 that are in queue should be encrypted when they are sent to
5089 the wire and not when they put to the queue.
5091 However, the problem is that the current system has not been
5092 designed to work that way. Instead, the packet is encrypted
5093 as soon as possible and left to the queue. The queue is then
5094 just purged into wire. There won't be any fixes for this
5095 any time soon. So, the current semantic for packet sending
5098 o If you send packet to remote host and do not force the send
5099 (the packet will be in queue) then all subsequent packets to the
5100 same remote host must also be put to the queue. Only after the
5101 queue has been purged is it safe again to force the packet
5104 o If you send all packets immediately then it safe to send
5105 any of subsequent packets through the queue, however, after
5106 the first packet is put to queue then any subsequent packets
5107 must also be put to the queue.
5109 Follow these rules and everything works fine.
5111 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Added new function silc_server_remove_clients_by_server to
5114 remove all client entries from ID list when the server connection
5115 is lost. In this case it is also important to invalidate all
5116 client entires as they hold the invalid server entry. This
5117 fixes fatal bug when server has lost connection and will reconnect
5120 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Made some sanity checks to silc_server_daemonise like to check
5123 whether the requested user and group actually exists.
5125 * Added sanity check to SKE's silc_ske_responder_finish to check
5126 that the public and private key actually is valid.
5128 * Invalidate the client's nickname when receiving Replace ID
5129 packet and the Client ID is being replaced. This means that the
5130 server will query the nickname if someone needs it (client)
5133 * Sort the ID Cache in client library when the ID Cache data
5134 has changed (needs sorting).
5136 * Do not allow for SILC client to create several connections to
5137 several servers. The client does not support windows right now
5138 and generating multiple connections causes weird behaviour.
5140 Irssi-silc client does support windows and can handle several
5141 connections without problems, see: www.irssi.org and SILC plugin.
5143 * Fixed some places where client was added to the IDList. The
5144 rule of thumb is following (in order to get everything right):
5145 If the client is directly connected local client then the
5146 `connection' argument must be set and `router' argument must be
5147 NULL to silc_idlist_add_client function. If the client is not
5148 directly connected client then the `router' argument must
5149 bet set and the `connection' argument must be NULL to the
5150 silc_idlist_add_client function.
5152 * The funtion silc_server_packet_send_local_channel actually did
5153 not check whether the client was locally connected or not. It
5154 does that now. Fixed a bug related to LEAVE command.
5156 * Fixed Remove Channel User payload parsing bug in server's
5157 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5159 * The server's silc_server_save_channel_key now checks also the
5160 global ID list for the channel as it might not be in the local
5161 list. Fixed a bug related to LEAVE command.
5163 * Is this the end of the [<unknown>] buglet that has been lurking
5164 around for a long time? A little for loop fix in server's
5165 silc_server_command_whois_parse that is used by both IDENTIFY
5166 and WHOIS command. At least, this was a clear bug and a cause
5167 of one type of [<unknown>] buglet.
5169 * WHOIS and IDENTIFY commands call the function
5170 silc_server_command_[whois/identify]_check function even if
5171 we are not router server.
5173 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Added --with-gmp configuration option. If set the GMP
5176 is always compiled in the SILC source tree. If not set then
5177 it is checked whether the system has the GMP3 installed. If
5178 it has then the GMP won't be compiled (the system's headers
5179 and library is used), if it doesn't have it then the GMP is
5180 compiled in the SILC source tree.
5182 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Changed RSA private exponent generation to what PKCS #1
5185 suggests. We try to find the smallest possible d by doing
5186 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5187 not security fix but optimization.
5189 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Added new config entry [Identity] to fork the server and run
5192 it as specific user and group. A patch from Bostik.
5194 * Imported Dotconf configuration library into lib/dotconf.
5195 This will be used to create the SILC configuration files later.
5196 It will appear in the distsribution after this commit.
5198 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * A big code auditing weekend happening. Auditing code for
5201 obvious mistakes, bugs and errors. Also, removing any code
5204 Removed files for being obsolete:
5206 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5207 inline in the file lib/silcutil/silcbuffer.h)
5209 o lib/silcutil/silcbufutil.c (the header has inline versions)
5211 Changed code to fix possible error conditions:
5213 o The buffer formatting routines now check that the destination
5214 buffer really has enough space to add the data. This applies for
5215 both buffer formatting and unformatting
5216 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5217 unformatting was changed to accomodate following rules:
5218 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5219 sent to the function while XXX_*STRING will not allocate or copy
5220 the data into the buffer. Instead it sets the pointer from the
5221 buffer into the pointer sent as argument (XXX_*STRING used to
5222 require that the pointer must be allocated already). This change
5223 makes this whole thing a bit more consistent and more optimized
5224 (note that the data returned in the unformatting with XXX_*STRING
5225 must not be freed now). The routines return now -1 on error.
5227 o Tried to find all code that use buffer_format and buffer_unformat
5228 and added return value checking to prevent formatting and
5229 especially unformatting errors and possible subsequent fatal
5232 o Changed ske->x and ske->KEY to mallocated pointers in
5233 lib/silcske/silcske.h. Fixed possible data and memory leak.
5235 o Added return value checking to all *_parse* functions. Fixed
5236 many memory leaks as well.
5238 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5239 so that buffer overflows would not happen. All code now also
5240 checks the return value as it can fail.
5242 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Added reconnection support to server if the normal server looses
5245 its connection to the router (for example if router is rebooted).
5246 The server performs normal reconnection strategy implemented
5247 to the server. Affected file silcd/server.c.
5249 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Added new packet type SILC_PACKET_SET_MODE that is used to
5252 distribute the information about changed modes (for clients,
5253 channels and clients channel modes) to all routers in the
5254 network. Updated the protocol specification accordingly.
5256 Added functions into silcd/packet_send.c and
5257 silcd/packet_receive.c: silc_server_send_set_mode,
5258 silc_server_set_mode.
5260 Added new files silcmode.[ch] into lib/silccore that implements
5261 the encoding and decoding of Set Mode Payload. Added new type
5262 SilcSetModePayload. Moved the definitions of different modes
5263 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5265 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Oops, a little mistake in server's connection authentication
5268 protocol. The protocol is not ended with FAILURE but with
5269 SUCCESS if the authentication is Ok. :) Affected file is
5272 * Implemented NICK_CHANGE notify handling in server in the file
5273 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5274 the local clients on the channel. After the changing nickname
5275 in router environment snhould work and the [<unknown>] nickname
5276 should appear no more.
5278 The silc_server_replace_id function that receives the Replace ID
5279 payload now sends the NICK_CHANGE notify type also in the file
5280 silcd/packet_receive.c
5282 * Changed WHOIS and IDENTIFY command to support the maximum amount
5283 of arguments defined in protocol specs (3328 arguments). This
5284 fixed a bug that caused problems when there were more than three
5287 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Added extra parameter, command identifier, to the
5290 silc_client_send_command so that explicit command identifier
5293 Changed that ID list routines uses specific command identifier
5294 when sending WHOIS/IDENTIFY requests to the server so that they
5295 can be identified when the reply comes back.
5297 Affected files lib/silcclient/command.[ch],
5298 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5300 * Added `sender' argument to silc_server_packet_send_to_channel
5301 to indicaet the sender who originally sent the packet to us
5302 that we are now re-sending. Ignored if NULL. Affected file
5303 silcd/packet_send.[ch].
5305 * Added some server statistics support in silcd/server_internal.h
5306 SilcServerStatistics structure and around the server code. Also
5307 send some nice statistics information when client is connecting
5310 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed channel ID decoding in server's JOIN command reply in
5313 silcd/command_reply.c
5315 * Fixed braodcasting of replace ID payload to not to send it if
5316 we are standalone server in silcd/packet_receive.c.
5318 * Fixed all channel message sending routines to not to send
5319 packets to clients that has router set, since they are routed
5320 separately in the same function earlier. Affects file
5321 silcd/packet_send.c and all channel packet sending functions.
5323 * In USERS reply, res_argv[i] are not allocated, the table
5324 is allocated. Thus changed that free the table, not its
5327 * In server's whois_check and identify_check if the client is
5328 locally connected do not send any WHOIS commands - they are not
5331 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Fixed some minor bugs in client when sending WHOIS command. The
5334 arguments was in wrong order.
5336 * Removed statis function add_to_channel from server in
5337 silcd/command.c that was previously used with the joining but
5340 * Tested USERS command in router environment successfully with two
5341 routers, two servers and two clients.
5343 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Reorganized the USERS command and command reply in client library
5346 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5347 When the command is given by user we register a pending command
5348 callback that will reprocess the command after the reply has been
5349 received from the server. When reprocessing the packet we then
5350 display the information. Thus, the USERS information is displayed
5351 now in the command callback instead of in the command reply
5352 callback. The processing of the command is same as previously
5353 when server has sent the command reply in the JOINing process.
5355 * Added to USERS command in silcd/command_reply.c to join the client,
5356 we didn't use to know about, to the channel after we've created
5357 a client entry for it. Also, for clienet we did know already still
5358 check whether it is on the channel or not and add it if not.
5360 * Removed silc_server_command_join_notify as the function and its
5363 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Changed the client's pending command handling to the same as the
5366 server's pending command handling. It is also now possible to
5367 execute command reply functions from other command reply
5368 function as the function callbacks for commands and command
5369 replies are one and same. The pending commands are not static
5370 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5371 in client connection context. Thus, pending commands are server
5372 connection specific as it is convenient.
5374 Changed the function silc_client_command_pending and
5375 silc_client_command_pending_del and added new function
5376 silc_client_command_pending_check. Removed the
5377 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5380 * Added cmd_ident, current command identifier, to the client
5381 connection context in lib/silcclient/client.h to keep track on
5382 command identifiers used in command sending. Client's command reply
5383 function handling now supports the mandatory command identifiers.
5385 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5386 funtions in client to fully support pending command callbacks.
5388 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5389 as one of the arguments to the application in the command reply
5392 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5393 before first releasing SILC but came back. Now it is removed again
5394 and should come back nomore. The FORWARDED flag was used only
5395 by the JOINing procedure by forwarding the command packet to router.
5396 Now, the JOINing procedure has been changed to more generic (due
5397 to various router environment issues) and FORWARDED is not needed
5398 anymore for anything. The protocol specification is yet to be
5401 Now, removed silc_server_packet_forward from server and the flag
5402 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5404 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Renamed NAMES command to USERS command. The NAMES was named that
5407 due to historical reasons. Now it is renamed. Also, rewrote
5408 parts of the USERS command. The nickname list is not sent anymore
5409 by the server. Only Client ID and mode lists are sent in the USERS
5410 command. Changed this also to the protocol specification.
5412 The client now resolves the names and stuff after it receives
5413 the USERS list from the server when joining to the channel.
5415 * WHOIS and IDENTIFY commands has been changed to support multiple
5416 Client ID's per command. One can now search for multiple users
5417 in the network by sending only one WHOIS or IDENTIFY command.
5418 Changed the code and the protocol specifications.
5420 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5421 uses silc_server_command_whois_parse to parse the request. */
5423 * If normal server, do not parse the WHOIS and IDENTIFY requests
5424 before sending it to the router. Saves some time.
5426 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Fixed JOIN command on client library. Wrong number of arguments
5429 used to crash the client.
5431 * Added silc_server_channel_has_global function to check whether
5432 channel has global users or not.
5434 * Added silc_server_channel_has_local function to check whether channel
5435 has locally connected clients on the channel.
5437 * The silc_server_remove_from_one_channel now checks whether the
5438 channel has global users or not after given client was removed from
5439 the channel. It also checks whether the channel has local clients
5440 on the channel anymore. If it does not have then the channel entry
5441 is removed as it is not needed anymore.
5443 * The silc_server_notify now checks on JOIN notify whether the joining
5444 client is one of locally connected or global. If it is global then
5445 the channel has now global users on the channel and that is marked
5446 to the channel entry. Also, it now saves the global client to
5447 global list who is joining and JOINs it to the channel. This is
5448 for normal server, that is.
5450 Changed silc_server_send_notify_on_channel,
5451 silc_server_packet_relay_to_channel and
5452 silc_server_packet_send_to_channel check if we are normal server
5453 and client has router set (ie. global client) do not send the
5454 message to that client, as it is already routed to our router.
5456 * Implemented LEAVE notify type handling in silc_server_notify
5459 * Tested LEAVE command in router environment successfully. Tested
5460 with two routers, two servers and two clients.
5464 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5466 * Implemented SIGNOFF notify type handling in silc_server_notify
5469 * silc_server_remove_id now removes the client entry from all channels
5470 it has joined and thusly sends SIGNOFF notify type.
5472 * Rewrote the NAMES list generation in server by removing two excess
5473 loops. The lists are created now inside one loop.
5475 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * silc_server_remove_channel_user checks now also global list
5478 for channel and client.
5480 * silc_server_new_channel_user checks now both local and global
5481 list for channel and client. Fixed a bug in client id decoding.
5482 Used to decode wrong buffer.
5484 * silc_server_channel_message checks now both local and global
5485 list for channel entry.
5487 * Tested channel joining (hence JOIN) in router environment
5488 successfully. Tested with two routers, two servers and two
5491 * Tested channel message sending in router environment successfully.
5493 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added silc_server_save_channel_key into server.[ch] to save the
5496 received channel key in Channel Key payload processing. It is
5497 also used in JOIN command reply handling.
5499 Equivalent function silc_client_save_channel_key added into
5500 client.[ch] into client library.
5502 * Changed JOIN command reply to send information whether the channel
5503 was created or not (is existing already) and the channel key
5504 payload. Changed protocol specs accordingly.
5506 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5507 the request was sent by ID and not by nickname. Crashed on
5510 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5513 now correctly save the received data.
5515 * silc_server_free_sock_user_data now notifies routers in the
5516 network about entities leaving the network.
5518 At the same time implemented functions silc_server_remove_id
5519 and silc_server_send_remove_id to receive and send REMOVE_ID
5520 packets. The packet is used to notify routers in the network
5521 about leaving entities. The ID removed will become invalid in
5524 * Added function silc_idlist_del_server into server. Removes and
5525 free's server entry from ID list.
5527 * silc_server_private_message function now checks, if we are router,
5528 that the destination ID really is valid ID, naturally.
5530 * In router when NEW_ID packet is received (for new client) the
5531 hash of the Client ID is saved in the ID Cache but the
5532 client->nickname is set to NULL, instead of putting the hash
5535 IDENTIFY command now also checks that client->nickname must be
5536 valid. If it is not if will request the data from the server who
5537 owns the client. Added new function
5538 silc_server_command_identify_check.
5540 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5541 to set the command to already allocated Command Payload.
5543 * Tested private message sending in router environment with two
5544 routers, two servers and two clients. Fixed minor bugs and now
5547 * Fixed segfault from client's NAMES command. Used to crash if
5550 * Forwarded packets must not be routed even if it is not destined
5551 to the receiver. Changed server code comply with this.
5553 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added `require_reverse_mapping' boolean value to ServerParams
5556 structure. If TRUE (not default) the server will require that
5557 the connecting host has fully qualified domain name.
5559 If the reverse mapping is not required and hostname could not be
5560 found the IP address is used as hostname.
5562 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Implemented version string checking to both client and server.
5565 The check is incomplete currently due to the abnormal version
5566 strings used in development version of SILC.
5568 * Changed all command functions in server to use the new
5571 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Changed char *data to unsigned char *data in ID Cache system to
5574 support binary data as ID Cache data. Changed code to support
5575 binary data in lib/silccore/idcache.c.
5577 * Renamed silc_server_packet_relay_command_reply to
5578 silc_server_command_reply as it is normal packet receiving
5579 function. Rewrote the function to accept command replys for
5580 servers and not only for clients.
5582 * Mark remote router always as registered server if we are connecting
5583 to it. Otherwise, commands sent by the router to us are ignored.
5585 * All ID List find routines now returns the ID Cache Entry pointer
5586 as well if requested.
5588 * WHOIS command works now in router environment, tested with two
5589 routers, two servers and two clients.
5591 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5592 in router environment (as it is almost equivalent to WHOIS) but
5593 hasn't been tested thoroughly. Added new functions:
5595 silc_server_command_identify_parse
5596 silc_server_command_identify_send_reply
5597 silc_server_command_identify_from_client
5598 silc_server_command_identify_from_server
5600 * Disabled route cache adding because adding two different ID's with
5601 same IP replaces the old cache entry thus giving wrong route.
5602 The entry->router->connection is always the fastest route anyway
5603 so route cache may not be needed. Of course, new routes maybe
5604 established after receiving the ID when the entry->router->connection
5605 might not be anymore the most optimal.
5607 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Add route cache for received ID for fast routing.
5611 * Added silc_server_packet_route to route received packet on router
5612 that is not destined to us.
5614 * Renamed silc_server_get_route to silc_server_route_get.
5616 * Added id_string and id_string_len fields into SilcServer to
5617 include encoded ServerID for fast comparing without excess
5618 encoding of the ID's.
5620 * Cleaned up WHOIS command on server side. Added following static
5623 silc_server_command_whois_parse
5624 silc_server_command_whois_check
5625 silc_server_command_whois_send_reply
5626 silc_server_command_whois_from_client
5627 silc_server_command_whois_from_server
5629 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5630 arguments in command replies. All command functions should be
5631 updated to use this macro.
5633 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Minor typo fixes on command reply handling on server.
5637 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Added silc_server_command_add_to_channel internal routine to add
5640 the client to the channel after router has created the channel and
5641 sent command reply to the server.
5643 * Added generic silc_server_send_command to send any command from
5646 * Use static buffer with ID rendering instead of duplicating data.
5648 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Fixed a channel user mode bug when joining to a channel server gave
5651 everybody channel founder rights, oops.
5653 * We mark ourselves as the router of the incoming server connection
5654 if we are router ourselves. This way we can check in some packet
5655 sending functions whether it is locally connected server. For
5656 incoming router connections we put NULL.
5658 * For router sending packets locally means now always sending the
5659 packet cell wide; to local clients and local servers. For normal
5660 server sending packet locally means sending it to only local
5663 * Fixed the JOIN command to really work in router environment. If the
5664 channel is created it is always created by the router. Router is
5665 also responsible of making the initial joining to the channel,
5666 sending JOIN notify to the sending server and distributing
5667 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5668 does not exist server doesn't do anything else but forward the
5669 command to the router which performs everything.
5671 * Added silc_server_send_channel_key function to send the Channel Key
5674 * Added silc_server_create_channel_key to create new channel key. The
5675 channel key is now re-generated everytime someone joins or leaves
5676 a channel, as protocol dictates. Note: channel->key_len is the
5679 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5682 packet_receive.[ch] to separate packet sending and receiving
5683 routines. The server.[ch] now includes everything else including
5684 actual packet processing (writing and reading data) and other
5687 Renamed silc_server_private_message_send_internal to
5688 silc_server_send_private_message. The routine is still though
5689 used only to relay private messages as server does not send
5690 private messages itself.
5692 Renamed silc_server_new_channel to silc_server_create_new_channel
5693 and added new function sicl_server_new_channel that handles the
5694 incoming New Channel packet. Added also new sending function
5695 silc_server_send_new_channel to send New Channel Payload.
5697 * Added new function silc_server_notify to process incoming notify
5698 packet to the server/router. Server may then relay the notify
5699 to clients if needed.
5701 * Added new function silc_server_new_channel_user to process incoming
5702 New Channel User packet. Router will redistribute the packet and
5703 send JOIN notify to its local clients and locally connected servers
5704 if needed. Normal server will send JOIN notify to its local client
5705 on same channel when received this packet. Added also corresponding
5706 sending function silc_server_send_new_channel_user to sent the
5709 * Added boolean route argument to send_notif_to_channel and
5710 packet_send_to_channel functions to attempt to route the packet
5711 if it is TRUE and send only locally if it is FALSE.
5713 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * silc_server_replace_id now broadcasts the received replace ID
5716 packet if it is not broadcast packet already. The router must
5717 broadcast to inform other routers about changed ID.
5719 * Added backpointer to server's router into SilcServer context in
5720 silcd/server_internal.h.
5722 * Fixed silc_server_packet_broadcast to send correct broadcast
5725 * The channel key is now distributed to the local client as soon
5726 as it is received from the router (in router environment) so that
5727 no other packet may be sent for the channel until client has
5730 * silc_server_remove_channel_user now broadcasts the received
5731 Remove Channel User packet if it is not broadcast packet already.
5732 The router must broadcast to inform other routers about removed
5735 * Added users field into SilcPacketContext that is a reference count
5736 of the context. One can increase the reference count by calling
5737 silc_packet_context_dup which is now changed to just increase the
5738 reference count instead of duplicating the data. The reference
5739 count is decresed by calling silc_packet_context_free that will
5740 free the data after the reference count hits zero.
5742 For now on the packet context and everything allocated into it
5743 (including the raw packet from network) must be freed by calling
5744 the new silc_packet_context_free function. Added also new function
5745 silc_packet_context_alloc that must be used now to allocate the
5746 context. This also means that if a routine is asynchronous from
5747 silc_[client/server]_packet_parse_type the packet context must
5748 be duplicated by calling silc_packet_context_dup. Otherwise it
5749 gets free'd after silc_[client/server]_packet_parse_type returns.
5750 Also, one must remember that if packet is duplicated then its
5751 reference count must be decresed by calling the free function as
5752 many times as it was duplicated.
5754 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5755 from both client and server.
5757 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Made joining to a channel working in router environment.
5761 * Cleaned up JOIN command on server side and create function
5762 silc_server_command_join_channel internal routine to make the
5765 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Changed silc_command_pending list to SilcDList. Also, added
5768 `ident' field to SilcServerCommandPending structure to identify
5769 the reply and to call correct callback.
5771 Added silc_server_command_pending_check function to replace the
5772 corresnponding macro. The silc_command_pending list is not
5775 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5776 to set identifier to previously allocated Command Payload. It
5777 is used to set identifier for command when resending Command
5780 * Added silc_command_payload_encode_payload to encode Command
5781 Payload buffer from SilcCommandPayload structure.
5783 * Added silc_argument_payload_encode_payload to encode Argument
5784 payload buffer from SilcArgumentPayload structure.
5786 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Changed WHOIS command to support router connection on server side.
5789 The whois request is always sent to router unless the server is
5790 standalone server. After server has received the reply from the
5791 router will it send the reply to the client.
5793 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5794 broadcast received broadcast packet. The function is used only
5795 by router. The broadcast packet is always sent to the router's
5798 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5799 render given ID to printable string, for log files for example.
5801 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Made basic router to router connections working. At least they
5804 can now connect to each other but nothing really works the way
5805 they are supposed - yet.
5807 * Added new initiator token to RouterConnection configuration
5808 file in silcd/serverconfig.[ch]. It is used to tell whether we
5809 are the initiator to the remote router or whether we'll expect
5810 the other end to connect.
5812 * Moved registering of listener task to silc_server_init, hence
5813 the server starts listenning as soon as it is run, even if it
5814 does not have connections to other routers. Let's see how well
5817 * Changed default connection retry timeouts for more suitable in
5820 * Removed cipher and such arguments from silc_idlist_add_client
5821 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5822 Added new function silc_idlist_add_data to add the keys and stuff
5825 * Added SilcIDListData structure and added it to SilcClientEntry
5826 and SilcServerEntry as their first field in the structure. This
5827 way we can explicitly cast the ID entries to the SilcIDListData
5828 structure and get common data for the entries. In past, we had
5829 to first check what type of connection it is and then cast it to
5830 correct ID entry type. Now, we can directly cast the opaque
5831 pointer to the SilcIDListData (no matter what ID entry it actually
5832 is) and get the data needed.
5834 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5837 in some circumstances even if threre were timeout tasks, though not
5838 IO tasks, but tasks anyway. Now fixed.
5840 * Defined SilcServerConnection structure to hold connection specific
5841 stuff about directly connected servers and routers. The definition
5842 is currently in silcd/server_internal.h. I thought about having
5843 a bit more important role fro this struct but for now it is used
5844 only when connecting to other server (or router actually).
5846 * Added connecting retry support in server when connecting to
5847 router(s). The retry feature implement exponential backoff
5848 algorithm. Also, added SilcServerParams structure to hold default
5849 parameters for server. For now, it include these retry settings
5850 and are hard coded. After server is moded to be as Silc Server
5851 Library this structure will be more important.
5853 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Changed client librarys channel->clients table to SilcList and
5856 changed code accordingly.
5858 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Changed client's channel table to SilcList and changed code
5861 accordingly. Also changed SilcChannelClientEntry to include back-
5862 pointer to the channel so that client entry can use that structure
5863 as list as well and we have fast cross-reference to the channel.
5864 This change dramatically decreased the complexity of channel
5865 handling with client entry and vice versa (removed one extra
5866 loop when searching for channel entry from many functions).
5868 * Changed server->sim from table to SilcDList and changed code
5871 * NAMES command can now be used from user interface. It will show
5872 the user list on the channel, neatly.
5874 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5875 Code now saves realname of the user if it becomes available.
5877 * Renamed configure.in to configure.in.pre and made ./prepare
5878 script to automatically add correct version string to
5879 configure.in which it creates from configure.in.pre.
5881 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * NAMES command reply now shows users mode with the nickname when
5886 * Moved silc_client_ch[u]mode[_char] functions from
5887 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5888 place sucks, they are utility functions and should be in some
5891 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5893 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5896 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Added TRQ (efficient deque and list library) into lib/trq. This is
5901 a very good list library that is currently used in the SILC. Defined
5902 SilcList API over the library because I didn't like the API very
5903 much. See lib/trq/silclist.h for the API and examples of how to
5904 use the API. Fixed various places in the code to use the new
5905 SilcList API. The SilcList is meant for lists that has a structure
5906 already defined as a list. It is not suitable to add just some
5907 context to the list (in TRQ, the context is the list actually).
5909 So, I defined SilcDList that can be used for the purpose where
5910 predefined list structure does not exit. This can be used as
5911 such list. Now some context just can be added to the SilcDList.
5912 Currently this list is not used in the SILC just yet, though there
5913 are a lot places where this can replace dynamically allocated
5914 tables and I will fix these places, later, to use SilcDList.
5915 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5916 and use TRQ internally).
5918 Also fixed some annoying warning messages that the original TRQ
5919 code generated. Also minor changes to TRQ's Makefile.in.
5921 * Added support for querying by Client ID to both WHOIS and
5922 IDENTIFY commands into server, as required by the protocol.
5924 * Removed method function pointers from SilcBuffer structure. They
5925 weren't used to anything and just increased the context size for
5926 no good reason. This change also made silc_buffer_alloc and
5927 silc_buffer_free functions inline functions.
5929 * Disabled command flooding detection support until it's fixed so
5930 that it accepts commands in but does not execute them more than once
5933 * Added silc_net_localhost(), to return local hostname, into
5934 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5935 that must be initialized before calling silc_client_init.
5937 * Added new function: silc_server_send_notify_on_channels to send
5938 notify messages to all channels client has joined. It is assured
5939 that the message is sent only once per client.
5941 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5942 lib/silcutil/silcutil.[ch] as silc_format function. The new
5943 function is generic and is used by server as well, not only by
5944 the logging routines.
5946 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5947 the provided version string was not acceptable. Added new function:
5948 silc_ske_check_version into lib/silcske/silcske.h. The function
5949 must be implemented by the application (client or server) and it
5950 does not reside in the SKE library. The function checks the version
5951 string remote end sent.
5953 * Added back pointers (to opaque context and to SilcSocketConnection)
5954 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5956 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5957 duplicate packet context structure.
5959 * Changed `notify' client operation to send same arguments as client
5960 receives from server except for ID's. ID's are mapped to correct
5961 ID entry and that is returned. Also, if channel entry is not sent
5962 by server but the notify is for channel the channel entry is sent
5963 to application (otherwise application doesn't know that it is for
5964 channel (library gets it from packet's Destination ID)).
5966 * Added silc_client_remove_from_channels into client library to
5967 remove a client from all channels it has joined to. Used when
5968 received SIGNOFF notify from server. Added also new function
5969 silc_client_replace_from_channels to replace old ID entry with
5970 new ID entry on all channels. Used when received NICK_CHANGE
5973 * Fixed ID Cache list handling in silc_idlist_get_client in
5974 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5975 to get (or query) client by ID.
5977 * Updated TODO list.
5979 * Added connection authentication status message defined by the
5980 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5981 support for these into the code in client and server side.
5983 * Added generic function silc_client_send_command to send any command
5984 with variable argument list. Application should use this function
5985 to send commands if the command functions provided by the library
5986 does not suite for the application's user interface needs.
5988 * Added new `failure' client operation. Application is notified about
5989 received failure packet if client is executing a protocol. In this
5990 case the protocol's execution has failed.
5992 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5993 is required by the protocol.
5995 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5996 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5999 * Added status flag to SilcSKE object to indicate realtime status
6000 of the SKE protocol.
6002 * Application receives now exactly same command reply arguments as
6003 the library receives from server. However, if ID is received the
6004 corresponding ID entry is returned to the application (eg. Client
6005 ID is mapped to correct SilcClientEntry entry and that is returned).
6006 Changed command_reply client operation due to this change.
6008 * Changed all ID's in commands and in command replys as ID Payloads.
6009 Change affected both client and server side codes.
6011 All ID's sent in SILC network (with execption of ID's in SILC
6012 Packet header) are sent in ID Payload to support variable length
6015 * Server now notifies nick changes and notifies all clients on
6016 the channels about the new nickname (about the new Client ID,
6019 * Implemented CMODE command to change channel modes. Supports all
6020 channel modes defined by the protocol specs except ban and invite
6021 lists. (Also, private channel key mode is supported but support for
6022 setting private channel key in client is missing, thus, this mode
6023 has no effect on client side (except that server requires that the
6024 client uses private channel key and normal channel traffic does not
6027 Also, invite mode works per se, but INVITE command does not work
6028 yet correctly, so you can set channel as invite only channel but
6029 inviting clients to the channel does not work (it is yet to be
6030 thought what's the best way to do it).
6032 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6033 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6034 Implemented CUMODE command to change user's mode on the channel.
6035 Supports all modes defined by the protocol specs.
6037 * Added NAMES command reply to return users modes on the channel.
6039 * Removed unnecessary and slow ciphers from lib/silccrypt.
6041 * Set SO_KEEPALIVE option to connection sockets by default.
6043 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6045 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6046 redefined the Notify Payload into protocol specs.
6048 * Added silc_id_payload_parse_id to get ID directly from raw
6051 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6054 accept searching by Client ID as well.
6056 * Added support for LEAVE and SIGNOFF notify types in client library.
6058 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6059 to parse ID Payload from raw data.
6061 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Added flags parameter into silc_ske_assemble_security_properties
6064 function in lib/silcske/silcske.[ch].
6066 * Changed notify client operation to fit better for notify messages
6067 sent by server. The notify payload received from server is now
6068 passed to the application (after parsing it to SilcNotifyPayload).
6069 It is application's responsibility to retrieve the arguments
6070 from the payload and show the message the way it wants. The message
6071 sent by server is implementation specific.
6073 * Changed public keys to comply with the protocol specification.
6074 Old public keys are not supported anymore and are not compatible.
6076 * Removed nickname from Channel Payload as the latest draft removed
6077 it. The client must resolve the nickname from the NAMES command
6078 reply received when it joined the channel.
6080 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6082 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Fixed some errors in protocol specification drafts.
6086 * Created lib/silccore/silcnotify.c to implement Notify Payload
6087 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6088 generic payloads described by protocol specifications. The file
6089 includes implementations for ID Payload and Argument Payload.
6091 * Changed Command Payload implementation to use the new Argument
6092 Payload. Changed command_xxxx_payload to command_payload_xxxx
6093 to comply with SILC coding conventions.
6095 * Added suppport for Argument Payload handling in Notify Payload
6096 implementation as protocol requires it. Added the new support
6097 into server and client lib as well.
6099 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added support for multiple nicknames on same channel. [n] is
6102 added locally to the nickname if there are more than one same
6103 nicknames on the channel.
6105 * Server now sends all nicknames that matched WHOIS request.
6106 Client also shows the list received from server.
6108 * Added TOPIC command to client side. User can now set and show
6109 current topic on channel.
6111 * Added MOTD command to client and server. Also, server sends the
6112 motd when client connects to the server.
6114 * Changed version strings to comply ISO 8601.
6116 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Fixed protocol error handling in client library. It should now
6119 cope even if the SKE fails for some reason.
6121 * Made new protocol specification drafts for submitting to IETF.
6123 * Implemented TOPIC command to server in silcd/command.c.
6125 * Added two new notify types into lib/silccore/silcnotify.h:
6126 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6127 notify nickname change and topic setting/change on a channel.
6129 * API change of command_reply operation in client library. The
6130 application gets now the status type received from server as well.
6132 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6136 * Cras fixed and optimized the packet handling even further and
6137 it should work now. Minor change to the prototype of function
6138 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6140 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Added new function into lib/silcutil/silcschedule.[ch]:
6143 silc_schedule_with_fd to select() a specified fd. The function
6144 returns after timeout expires or data arrives or goes. The
6145 function is used by packet routines to wait that all data is
6146 received from network.
6148 * Fixed data reading from network in lib/silccore/silcpacket.c.
6149 The code now assures that all data is read from the fd and then
6150 continues packet processing. This was a bug fix since the code
6151 used to drop some data in some circumstances.
6153 * Added new function into lib/silcclient/client.[ch]:
6154 silc_client_start_key_exchange to start key exchange after
6155 connection has been established to server. The code internally
6156 now uses this funtion but its main purpose was to provide it
6157 for applications that perform their own connecting. After
6158 application has created a connection it merely calls this
6159 function to start the key exchange between client and server.
6160 The library takes care of everything else after that.
6162 Updated also lib/silcclient/README to explain the usage of
6165 * Do not send to application information that connection has
6166 been established. Application gets notified it by connect
6169 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Applied cras's patch to add silc_schedule_one function. The
6172 function runs scheduler once and returns.
6174 * Fixed the scheduler after cras messed it up. The timeout
6175 handling works now as it's supposed to work.
6177 * Added into lib/silccore/ silcnotify.h to include notify
6178 message types support. Changed silc_server_send_notify*
6179 functions, in server.[ch], to support those new notify types.
6180 Added the support for the notify types into client library,
6181 as well. Added new notify client operation into ops.h in
6184 * Changed silc_server_packet_send_to_channel to send normal
6185 packets instead of just channel message packets. The function
6186 is now used to send the notify packets to channels. It is not
6187 used to send channel message packets anymore, as server never
6190 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6191 va_arg()s as it seems to require it nowadays. I guess, if SILC
6192 is compiled with older va_arg() the new code should work anyway.
6194 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Splitted core library. Core library (lib/silccore) includes
6197 now only SILC protocol specific core (and common) components.
6198 Created new utility library (lib/silcutil) that includes more
6199 generic purpose stuff. The stuff for util library was taken
6200 from the old core library. This was minor and easy split.
6202 * Created SILC Client Library (lib/silcclient) that includes
6203 implementation of the SILC client without user interface. This
6204 was major move from silc/ directory. The code has been changed
6205 so that it is transparent towards the user interface. The
6206 silc/ directory includes now the same user interface as before
6207 and it uses the new client library. Read lib/silcclient/README.
6208 Basicly, the client library performs everything else related
6209 to SILC except user interface handling. Also, configuration
6210 files are considered to be part of user interface and library
6211 does not handle them.
6213 This change also changed a lot of structures, function naming etc.
6214 Most important change was that SilcClientWindow object was
6215 renamed to SilcClientConnection in the client library. Created
6216 also new file lib/silcclient/ops.h. Also added new files
6217 silc/local_command.[ch] and silc/client_ops.[ch].
6219 All these changes were made to make it easier for user interface
6220 designers to create what ever user interface for the SILC client
6223 It is also expected that the server will be moved to lib
6224 directory as well and SILC Server Library will be created;
6225 sometimes in the future.
6227 * Removed Local commands from lib/silccore/silccommand.h as
6228 they are application specific and new client library does not
6229 handle any of those anymore.
6231 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6232 old client implementation in silc/.
6234 * Added support for callback functions in SILC_LOG_* macros.
6235 Application can now set its own callbacks that will be called
6236 instead of using the default functions that will always print
6237 the debug messages to stderr (or stdout). Also, debugging can
6238 now be disabled by setting silc_debug to FALSE and re-enabled by
6239 setting it to TRUE. Note, that logging will still work even
6240 if debugging is disabled.
6242 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6243 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6244 silc_log_reset_debug_callbacks.
6246 * To enable debugging in silc client one must give now -d
6247 option on command line.
6249 * Changed silc_schedule_init to automatically allocate task queues
6250 if they are not allocated before calling it.
6252 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Added GMP 3.1 into math library.
6256 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6259 a channel in SILC network. The packet is used by servers and
6260 routers to notify other routers that user has left a channel.
6261 This little feature was missing until now. Added the feature
6262 to protocol specification as well.
6264 Added functions: silc_server_send_remove_channel_user and
6265 silc_server_remove_channel_user into server.[ch].
6267 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6268 lib/silccore/silcpacket.h. However, they are not implemented
6271 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Fixed joining to a channel and sending channel messages
6274 between server and router. The channel message sending should
6275 now work inside a cell.
6277 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Fixed the private message sending between server and router.
6280 The private message sending should now work inside a cell.
6282 * Added silc_server_replace_id into server.[ch] to replace
6283 existing ID in the SILC network.
6285 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6286 and silc_idlist_replace_server_id into idlist.[ch] in server.
6288 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Fixed the server to server connections. Server can again now
6291 connect to router. Router to router connections probably does
6294 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Added dynamic protocol registering support. Now protocols can
6297 registered and unregistered on the fly. Patch by cras.
6299 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Added lib/contrib directory to hold routines that some platforms
6302 don't have but are needed by SILC.
6304 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6305 into lin/contrib to provide getopt() and getopt_long() for
6306 those who don't have it.
6308 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Added AWAY command to client. When away message is set and
6311 client receives a private message packet the client automatically
6312 replies to the sender with the away message.
6314 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6315 bug seemed to be the cause of recent problems when compiling
6318 * Added version detection support to SKE protocol specification
6319 and added the new changes to the SKE implementation as well.
6320 There were other minor changes in the SKE protocol as well.
6322 Many changes in lib/silcske/silcske.[ch] and in
6323 lib/silcske/payload.[ch].
6325 * Added ^U functionality, clear input line. Patch from cras.
6327 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Mainly small bugfixes on core library. Fixed some debugging
6330 logging and buffer overflow in silclog.c.
6332 * Updated config.sub and config.guess on the distribution tree.
6334 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Added command lagging support in server. Client may execute
6337 commands now only once in two seconds.
6339 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6341 * Optimized packet reception. MAC computation and checking is now
6342 also more optimized. A lot previously duplicated code is now
6343 used as generic by both client and server.
6345 * Fixed key pair generation in clientutil.c
6347 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Added into lib/silccore/silcbufutil.[ch] new function;
6350 silc_buffer_realloc.
6352 * Moved generic packet sending/encryption functions to
6353 lib/silccore/silcpacket.[ch] from client and server. Some
6354 rewriting of the functions.
6356 * Moved all generic packet reception/decryption functions to
6357 lib/silccore/silcpacket.[ch] from client and server. The
6358 packet processing is now much cleaner in both client and server.
6359 These were major changes in both client and server.
6361 * Created many common functions in server to do packet sending.
6362 Previously code were duplicated a lot, this has been removed
6365 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Rewrote major parts of the ID cache system. Don't know
6368 whether it is better now or not but at least the API is more
6371 * Major rewrite on ID cache stuff on client because of the ID
6372 cache API changes. Added idlist.c to client.
6374 * Also major rewrite on ID cache stuff on server as well.
6375 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6376 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6377 in hand, instead they are all put into the ID cache system now.
6378 All server_idlist_* routines uses ID cache now instead of
6379 traversing its own lists (those lists does not exist anymore).
6380 SilcIDList though still exists. Also, SilcXXXEntry's are
6383 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Finally made the SKE implementation compliant to the protocol
6386 specification. All mp integers are now binary encoded as
6387 opposed being HEX encoded.
6389 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6392 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6393 functions: silc_[encode/decode]_pem. Also added function
6394 silc_encode_pem_file to PEM encode with newlines ('\n') for
6397 * SILC public keys are now encoded either PEM or binary. Same
6398 option is for private keys as well. By default private keys
6399 are binary encoded and public keys PEM encoded. Silly HEX
6400 encoding were removed.
6402 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6403 function to create fingerprints.
6405 * Fixed a bug in SHA1; does not change the original data anymore.
6407 * Partly implemented INFO command on client and server side.
6408 Fixed CLEAR command. Changes to SERVER command; show current
6409 server(s) when giving command without arguments. Added
6410 VERSION command to client.
6412 * Added check to server that unregistered connections cannot
6413 execute commands (unless it is specificly allowed).
6415 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Fixed screen refresh.
6419 * Fixed channel joining bug from client. On some circumstances
6420 client tried to join to a channel it had already joined.
6422 * Added public key verification process into client's protocol.c.
6423 The client now verifies the public key from user and saves
6424 it into ~./silc/serverkeys/ directory.
6426 Added into: clientutil.[ch]: silc_client_verify_server_key.
6428 * Changed SKE protocol's silc_ske_initiator_finish function
6429 to accept callback function that verifies the received public
6430 key. Removed old silc_ske_verify_public_key function.
6432 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6435 silc_pkcs_private_key[_data]_set.
6437 * Made the password and public authentication more cleaner in
6438 server's protocol.c.
6440 * Removed historic and obsolete protocol `channel_auth' from
6441 both client and server.
6443 * Removed wrong way of sending command status messages from
6444 server to client in server's command.c. The old way violated
6445 protocol specification.
6447 Changes to silccore/silccommand.[ch]: removed
6448 silc_command_encode_status_payload -> not needed anymore,
6449 changed silc_command_encode_payload_va to accept extra
6450 argument on variable argument list. The argument type must
6451 now be provided to the function. Also, added new function:
6452 silc_command_encode_reply_payload_va which is same as
6453 normal command_encode_payload_va except command status type
6454 is provided as extra argument.
6456 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6458 * Added ~./silc directory handling. The directory includes the
6459 public and private keys for the client.
6461 Added silc_client_check_silc_dir, silc_client_create_identifier
6462 and silc_client_load_keys.
6464 * Implemented SILC protocol compliant public key. Added public
6465 and private key saving to and loading from files.
6467 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6468 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6469 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6470 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6471 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6473 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6474 silc_pkcs_load_[public/private]_key.
6476 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Added silc_server_get_route (route.[ch]) to get connection
6479 data for the fastest route for given ID.
6481 * Implemented INVITE command on client and server. The command
6482 were re-defined in the SILC Protocol Specification and the
6483 implementation now complies with the specification.
6485 * Implemented PING command on client and server.
6487 * Implemented NAMES command on client and server. The server side
