1 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Removed the command destructor entirely from the server's
4 command and command reply routines. It is not needed, and
5 its usage was buggy and caused crashes. Affected files are
6 silcd/command[_reply].[ch].
8 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
10 * Cancel protocol and NULL sock->protocol if timeout
11 occurred during protocol. Affected file silcd/server.c.
13 * Cancel protocol timeouts always before calling the final
14 callback, to assure that after final callback is called
15 no other state will be called for the protocol anymore.
16 Affected file silcd/protocol.c.
18 * Print error log if incoming connection configuration could
19 not be found. Affected file silcd/server.c.
21 * Fixed JOIN command to correctly save the founder mode
22 to the client on normal SILC server, when the channel
23 was created by the router. Affected file silcd/command.c.
25 * Fixed LIST command (hopefully) to send correct reply
26 packets. Affected file silcd/command.c.
28 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
30 * The silc_packet_receive_process now returns FALSE if the
31 read data was invalid packet, and TRUE if it was ok.
33 The server now checks that if unauthenticated connection
34 sends data and its processing fails the server will close
35 the connection since it could be a malicious flooder.
37 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
39 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
41 * Make sure the warning about error opening a log file is
42 printed only once and not everytime it fails (produces
43 too much useless log). Affected file lib/silcutil/silclog.c.
45 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
47 * Made the silc_server_daemonise() function more readable.
48 Affected file silcd/server.c.
50 * Pid file is now optional, the user may comment it out from
51 the config file. Removed define SILC_SERVER_PID_FILE, we
52 don't need a default any longer. Affected file
53 configure.in.pre, lib/Makefile.am.pre.
55 * Make some use of the pid file. The server now dies at startup
56 if it detects a valid pid file on his path. The server would
57 die anyway in this circumstance, because of the bind() failure.
58 Affected file silcd/silcd.c.
60 * No longer compiling lib/dotconf.
62 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
64 * Fixed JOIN command parsing not to crash. Affected file
65 lib/silcclient/command.c.
67 * Fied the NICK_CHANGE notify to add the new client entry
68 even it is resolved. This removes an <[unknown]> nick
69 thingy bug in the client. Affected file is
70 lib/silcclient/client_notify.c.
72 * Do not try to allocate 0 bytes (efence does not like it)
73 in lib/silccore/silccomand.c when encoding payload.
75 * Do not take IRCNICK as nickname in Irssi SILC client since
76 it is not possible to set nickname before hand connecting
77 the server (TODO has an entry about adding auto-nicking
80 * Changed the silc_server_command_pending to check whether
81 there already exists an pending entry with the specified
82 command, command identifier and pending callback. This is
83 to fix IDENTIFY and WHOIS related crashes that may register
84 multiple pending commands with same identifier. Affected
87 * Fixed the server to reconnect to the router even if it
88 was already reconnecting and EOF was received. This to
89 fix a possibility that the server wouldn't ever try to
90 auto-reconnect to the router. Affected file silcd/server.c.
92 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed the server's password authentication to use the
95 length of the locally saved password, and not the one
96 sent in the packet. Affected file silcd/protocol.c.
98 * Fixed same password authentication problem in the
99 Authentication Payload handling routines in
100 lib/silccore/silcauth.c.
102 * Yet another password authentication problem fixed with
103 channel password handling in silcd/command.c.
105 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
107 * If first character of string in silc_parse_userfqdn is '@'
108 then do not parse it. Affected file is
109 lib/silcutil/silcutil.c.
111 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
113 * Fixed minor bug in IDENTIFY command reply sending, which
114 caused various weird problems during JOIN when it was
115 resolving names for users. Affected file silcd/command.c.
117 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Fixed the IDENTIFY command reply sending to chech better valid
120 clients. It was possible to send incomplete list of replies.
121 Affected file silcd/command.c.
123 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
125 * Added silc_client_command[s]_[un]register functions now to
126 dynamically register the commands in client library. Removed
127 the static table of commands. This allows the client library
128 to call commands without causing the application to know about
129 what commands library has called.
131 Removed the INFO command reply kludge to detect when the command
132 was called by library. Now library use its own command reply
133 function for INFO command.
135 Added function silc_client_command_call to call a command.
136 Application can use it to call command, not access the structure
139 Now all commands that are sent by the client library (not
140 explicitly sent by application) use own command reply functions.
142 Affected files around lib/silcclient/ and in
143 irssi/src/silc/core/.
145 * Fixed the WHOIS command reply sending to chech better valid
146 clients. It was possible to send incomplete list of replies.
148 Fixed the WHOIS and IDENTIFY to send the request to router
149 if normal server did not do it and did not find any results.
151 Affected file silcd/command.c.
153 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
155 * Moved the internal data from SilcClient context into its
156 own file, not accesible to application. Affected files
157 lib/silcclient/client.h and lib/silcclient/client_internal.h,
158 and other files in client library.
160 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
162 * Added doc/examples installation target in Makefile.am.pre.
165 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
167 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
168 commands the found client entry will be removed from the
169 cache, after notifying application about the error. Affected
170 file lib/silcclient/command_reply.c.
172 * Changed the /MSG to check for exact nickname user gave, and
173 not let `nick' match `nick@host' if it is only one found. Now,
174 user must type the exact nickname (like nick@host2) even if
175 there are no more than one same nicks found. This is to avoid
176 a possibility of sending nickname to wrong nickname since
177 `nick' could match `nick@host'. Affected file is
178 irssi/src/core/silc-servers.c.
180 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
182 * Do not print "you are now server operator" or similar when
183 giving /away command. Affected files are
184 irssi/src/silc/core/client_ops.c, silc-servers.h.
186 * Made the silc_server_command_pending_error_check to send
187 the same command reply payload it received back to the
188 original sender of the command. This way all arguments
189 that was received by the server will be received by the
190 client too. Affected file silcd/command.c.
192 * Added the silc_idcache_add to return the created cache entry
193 to a pointer. Affected file lib/silccore/silcidcache.[ch].
195 * Add global clients to expire if they are not on any channel.
196 This is because normal server will never know if they signoff
197 if they are not on any channel. The cache expiry will take
198 case of these entries. This is done by normal servers only.
199 The affected files are silcd/command_reply.c,
200 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
202 * If server receives invalid ID notification for WHOIS or
203 IDENTIFY and the ID exists in the lists, it is removed.
204 Affected file silcd/command_reply.c.
206 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
207 in client then client entry that it matches is searched and
208 the nickname is printed on the screen for user. Affected
209 file irssi/src/silc/core/client_ops.c.
211 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
213 * Use cache entry expire time in the LIST command reply to
214 purge old entries from the cache after the LIST command
215 reply has been received. This way we don't have non-existent
216 entries in the cache for too long. Affected file is
217 silcd/command_reply.c.
219 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
221 * If we are normal server, and we've not resolved client info
222 in WHOIS or IDENTIFY from router, and it is global client,
223 we'll check whether it is on some channel. If it is not
224 then we cannot be sure about its validity and will resolve it
225 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
226 file silcd/command.c.
228 * Search channel by name (if possible) rather than by ID
229 in IDENTIFY command's command reply. Affected file is
230 silcd/command_reply.c.
232 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
234 * Distribute to the channel passphrase in CMODE_CHANGE notify.
235 Updated specs and implemented it. Affected file silcd/command.c,
236 silcd/packet_send.c and silcd/packet_receive.c.
238 * Implemented the <founder auth> payload handling in the JOIN
239 command. If provided all conditions for channel joining
240 except requirement to provide correct passphrase can be
241 overrided by the channel founder. Updated the protocol specs.
242 Affected file silcd/command.c.
244 Added support for founder auth in JOIN command in client
245 library. Fixed the parsing of the JOIN command now to support
246 all options as they should be. The affected file is
247 lib/silcclient/command.c.
249 * Optimized the WHOIS and IDENTIFY commands to send the request
250 to router only if it includes nicknames or other names. If
251 they include only IDs then check the local cache first before
252 routing. Affected file is silcd/command.c.
254 * Added channels topic announcements. Affected file is
255 silcd/packet_receive.c and silcd/server.c.
257 * Fixed the silc_server_send_notify_topic_set to really destine
258 the packet to channel. Affected file silcd/packet_send.c.
260 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
261 library. Affected file lib/silcclient/client_notify.c.
263 * Added UMODE announcements. Affected file silcd/server.c.
265 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
267 * Memory leak fixes in:
269 lib/silcutil/silcsockconn.c
270 lib/silcske/silcske.c
273 lib/silccrypt/silcpkcs.c
274 lib/silccore/silccommand.c
275 lib/silccore/silcidcache.c
280 * ROBOdoc documented the lib/silcske/groups.h file and a
281 bit changed the interface for better.
283 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
285 * Update the client entry context in the ID cache after
286 nick change. Affected file lib/silcclient/command.c.
287 Fixes the CUMODE command when regaining founder privileges,
288 and a little WHOIS problem.
290 * Fixed silc_net_gethostbyname to correctly call the
291 inet_ntop. Affected file lib/silcutil/silcnet.c.
293 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
295 * Added IPv6 support checking to the configure.in.pre, added
296 also --enable-ipv6 option to override the check. Affected
297 file configure.in.pre.
299 * The silc_thread_create now calls the start function
300 directly if threads support is not compiled in. Removes
301 ugly #ifdef's from generic code. Affected files are
302 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
304 * Added silc_net_gethostby[name/addr]_async to asynchronously
305 resolve. Affected files are lib/silcutil/silcnet.[ch].
307 * Added support for rendering IPv6 based server, client and
308 channel IDs. Affected file lib/silcutil/silcutil.c.
310 * Added support for creating IPv6 based server IDs. Affected
311 file is silcd/serverid.c.
313 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
315 * Added silc_net_gethostby[addr/name] into the
316 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
317 routines. Added silc_net_is_ip[4/6]. Affected file is
318 lib/silcutil/unix/silcunixnet.c. All routines that take
319 address as argument now supports both IPv4 and IPv6 addresses.
321 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
323 * Fixed LIST command reply sending in server. Affected file
326 * Server now sends the kicker's client ID in the KICK notify
327 to the kicked client. Affected file silcd/command.c.
329 * The client library now parses the kickers client ID and
330 UI displays it. Affected files lib/silcclient/client_notify.c
331 and irssi/src/silc/core/silc-channels.c, module-formats.c.
333 * Made all payload parsing function prototypes consistent.
334 They all take now const unsigned char * and uint32 pair as
335 the payload data instead of SilcBuffer. Changes all around
336 the source tree. Other unsigned char* -> const unsigned char*
337 changes around the tree as well.
339 * Optimized SFTP client and server packet sending not to
340 allocate new buffer for each packet but to recycle the
341 first allocated buffer. Affected files are
342 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
344 * Optimized the SFTP client to use SilcList instead of
345 SilcDList for requests, because it is faster. Affected file
346 is lib/silcsftp/sftp_client.c.
348 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
349 into lib/silccore/silcid.[ch].
351 Renamed silcpayload.[ch] into silcargument.[ch].
353 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
355 * If client entry is deleted with active key agreement
356 session, abort the session.
358 The silc_client_abort_key_agreement now calls the completion
359 callback with new SILC_KEY_AGREEMENT_ABORTED status.
361 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
364 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Don't use __restrict in older GCC's. Affected file is
367 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
369 * silc_net_localhost now attempts to reverse lookup the
370 IP/hostname. Affected file lib/silcutil/silcnet.c.
372 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
373 command. It can be used to gain founder privileges at
374 the same time when joining the channel.
376 Defined that the SILC_NOTIFY_TYPE_KICKED send the
377 kicker's client ID as well. Updated protocol specs.
379 Defined that the server must send SILC_COMMAND_IDENTIFY
380 command reply with error status to client who sent
381 private message with invalid client ID.
383 Updated the protocol specification.
385 * Added silc_server_send_command_reply to send any
386 command reply. Affected file silcd/packet_send.[ch].
388 * Added silc_id_payload_encode_data to encode ID payload
389 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
391 * The server now send IDENTIFY command reply with error
392 status if client ID in private message is invalid. Affected
393 file silcd/packet_receive.c.
395 * Save the server key file with server's IP address in
396 the filename instead of hostname. The affected file is
397 irssi/src/silc/core/client_ops.c.
399 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
401 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
404 * Added libtool support for compiling shared objects in
405 lib/silcsim. Affected file configure.in.pre and
406 lib/silcsim/Makefile.am. Original patch by cras.
408 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>

413 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
415 * Fixed silc_client_channel_message to not try to decrypt
416 the message twice if it resolved the destination client
417 information. This could cause of dropping one channel
418 message. Affected file lib/silcclient/client_channel.c.
420 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
422 * Added silc_client_run_one into lib/silcclient/silcapi.h and
423 lib/silcclient/client.c. This function is used when the SILC
424 Client is run under some other scheduler, or event loop or
425 main loop. On GUI applications, for example this may be
426 desired to used to run the client under the GUI application's
427 main loop. Typically the GUI application would register an
428 idle task that calls this function multiple times in a second
429 to quickly process the SILC specific data.
431 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
433 * Fixed silc_server_drop() for dropping the supplementary
434 groups as well, this could cause a security hole on some
437 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
439 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

443 to run server on foreground. A patch by debolaz.
444 Affected files silcd/server.c, silcd/silcd.c.
446 * Fixed MOTD to return the MOTD file server name. Affected
447 file silcd/command.c.
449 * Added INFO command reply handling to the Irssi SILC Client.
450 Affected file irssi/src/silc/core/client_ops.c.
452 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
454 * Fixed the silc_idcache_list_* routines to really support
455 the dynamic list. Fixes a crash. Affected file is
456 lib/silccore/silcidcache.c.
458 * Fixed the LIST command reply to really call LIST command's
459 pending callbacks. Affected file silcd/command_reply.c.
461 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
463 * Update conn->local_entry->nickname after giving NICK
464 command. Affected file lib/silcclient/command.c.
466 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
468 * Added the [pid] option to the silcd configuration file
470 Affected files: serverconfig.[ch] and silcd.c

474 * Save fingerprint in WHOIS command reply in server.
475 Affected file silcd/command_reply.c.
477 * Fixed NICK commands pending callback registration.
478 Affected file lib/silcclient/command.c.
480 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Use ++server->cmd_ident when sending commands in server,
483 instead of random number. Affected file silcd/command.c.
485 * Fixed GETKEY command reply to call actually GETKEY pending
486 command callbacks. Affected file silcd/command_reply.c.
488 * A bit stricter check for nicknames. Check for same nickname
489 in NICK command also. Affected file silcd/command.c.
491 * Do not call INFO command everytime client ID changes, only
492 during first connecting. Affected file lib/silcclient/client.c.
494 * Set the new nickname only after successful command reply for
495 NICK command is returned by server. Affected file
496 lib/silcclient/command.c.
498 * Remove nicknames from nicklist during server_signoff notify.
499 Should fix /NAMES bit more. The affected file is
500 irssi/src/silc/core/silc-channels.c.
502 * Added `fingerprint' field to the SilcIDListData in the
503 silcd/idlist.h to hold the fingerprint of the client's
506 Send the fingerprint of the client's public key in WHOIS
509 Affected files silcd/command.c, and silcd/idlist.[ch].
511 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
512 create fingerprint from given data.
514 * Show the fingerprint of the client's public key in WHOIS.
515 Affected files irssi/src/module-formats.[ch] and
516 irssi/src/silc/core/client_ops.c.
518 * Format the multiple same nicknames also during JOIN and
519 NICK_CHANGE notifys. Affected file is
520 lib/silcclient/client_notify.c.
522 * Do not print error on screen for invalid private message
523 payload since it can come if someone is sending private
524 messages with wrong key. Affected file
525 lib/silccore/silcprivate.c.
527 * Fixed multiple concurrent /PING crash. Affected file
528 lib/silcclient/command.c.
530 * Changed the wrong ID encoding. All IP addresses must be
531 in MSB first order in encoded format. They were encoded
532 wrong and was in LSB format. Affected files are
533 silcd/serverid.c, lib/silcutil/silcutil.c.
535 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
537 * Call the `connect' client operation through the scheduler
538 in case of error. Affected file lib/silcclient/client.c.
540 * Call the `failure' client operation even if the error
541 occurred locally during a protocol. Affected file is
542 lib/silcclient/protocol.c.
544 * Added support of sending LIST command to router from normal
545 server. This way normal server can get list of all channels
546 in the network too. Fixed the channel list sending in the
547 server too. Affected files are silcd/command.c, and
548 silcd/command_reply.[ch].
550 * Added silc_server_update_channels_by_server and
551 silc_server_remove_channels_by_server. They are used during
552 disconnection of primary router and in backup router protocol.
553 Affected file silcd/server_util.[ch], silcd/server.c and
554 silcd/server_backup.c.
556 * Fixed channel adding to global list in IDENTIFY command
557 reply in server. Affected file silcd/command_reply.c.
559 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
561 * If the incoming packet type is REKEY or REKEY_DONE process
562 that packet always synchronously. Fixes yet another MAC
563 failed error on slow (dialup) connections. Affected file
564 lib/silcclient/client.c and silcd/server.c.
566 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Call check_version SKE callback for initiator too. Affected
569 file lib/silcske/silcske.c.
571 * Implemented fix for security hole found in the SKE that was
572 fixed in the specification few days back; the initiator's
573 public key is now added to the HASH value computation.
574 Added backwards support for the old way of doing it too, for
575 old clients and old servers. Affected file is
576 lib/silcske/silcske.c.
578 * Enabled mutual authentication by default in SKE. If initiator
579 is not providing mutual authentication the responder will
580 force it. This will provide the proof of posession of the
581 private key for responder. The affected files are
582 lib/silcclient/protocol.c and silcd/protocol.c.
584 * Do not cache anymore the server's public key during SKE.
585 We do mutual authentication so the proof of posession of
586 private key is done, and if the server is authenticated in
587 conn auth protocol with public key we must have the public
588 key already. Affected file silcd/protocol.c.
590 * Added new global debug variable: silc_debug_hexdump. If
591 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
592 file lib/silcutil/silclog.[ch].
594 * Fixed compilation warning due to char * -> const char *.
595 Affected files lib/silcutil/silcnet.h, and
596 lib/silccore/silcauth.[ch].
598 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
600 * Fixed CMODE command when new channel key was created. If
601 the creation failed the old key was removed. Next time giving
602 same command would crash the server since the old key was
603 freed already. Affected file silcd/command.c.
605 * Fixed the silc_server_announce_get_channels to not crash
606 on reconnect. Affected file silcd/server.c.
608 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
610 * Added silc_log_set_debug_string function to set a regex
611 string to match for debug output. Only the function names,
612 or filenames matching the given debug string is actually
613 printed. This way it is possible to filter out those debug
614 strings that user is not interested in.
616 Fixed a bug in silc_string_regexify.
618 Affected files lib/silcutil/silclog.[ch], and
619 lib/silcutil/unix/silcunixutil.c.
621 * Changed the -d options in both server and Irssi SILC client
622 to take the debug string as argument. Affected files
623 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
625 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
627 * Added silc_hash_babbleprint to create a Bubble Babble
628 Encoded fingerprint. The encoding is developed by Antti
629 Huima (draft-huima-babble-01.txt), and it creates human
630 readable strings out of binary data. Affected file
631 lib/silccrypt/silchash.[ch].
633 * Print the babble print now in addition of fingerprint as well
634 in Irssi SILC client. Affected files are
635 irssi/src/fe-common/silc/module-formats.[ch],
636 irssi/src/fe-common/silc/core/client_ops.c.
638 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Fixed a security problem found in SKE. The initiator's
641 public key too is now added to the HASH hash value creation
642 which is signed by the responder to create the SIGN value.
643 This will prevent anyone in the middle to lie to the responder
644 about the initiator's public key. If this is done now, the
645 man in the middle will get caught. Updated the protocol
648 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
650 * Better installation directory handling. Configure module
651 paths and other paths automatically to example_silc* files
652 in doc/. A patch by toma.
654 * Fixed compiler warning from MPI library, and from SILC RNG.
657 * Added SILC_SERVER_PID_FILE to define the pid file for server.
658 It can be configured with ./configure. A patch by toma.
660 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Find correct make to use in prepare-clean. A patch by
663 toma. Affected file prepare-clean.
665 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
667 * Added irssi variables use_auto_addr, auto_bind_ip,
668 auto_bind_port and auto_public_ip.
670 * Changed the interface for silc_client_send_key_agreement
671 in lib/silcclient/silcapi.h
675 irssi/src/silc/core/silc-core.c
677 lib/silcclient/silcapi.h
678 irssi/src/silc/core/silc-channels.c
679 lib/silcclient/client_keyagr.c
682 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Added silc_pkcs_public_key_compare to compare two
685 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
687 * Check that the client who set the founder mode on the
688 channel is the same client that is giving the founder
689 mode to itself. It is done by comparing the saved public
690 key (it is saved even in the authentication is passphrase).
691 Affected file silcd/command.c.
693 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
695 * Do not process packet for disconnected socket connection.
696 Affected file lib/silccore/silcpacket.c.
698 * Process the DISCONNECT packet through scheduler in the
699 client library. Affected file lib/silcclient/client.c.
701 * Fixed the silc_client_packet_parse to not to increase
702 the packet sequence number if the conn->sock and the
703 current socket connection is not same. This can happen
704 for example during key agreement when the conn includes
705 multiple socket connections (listeners). Affected file
706 lib/silcclient/client.c.
708 * The sender of the file transfer request now provides also
709 the pointer (listener) for the key exchange protocol. If
710 the listener cannot be created then it sends empty key
711 agreement and lets the receiver provide the listener.
713 Added `local_ip' and `local_port' arguments to the
714 silc_client_file_send. If they are provided they are used,
715 if not then it will attempt to find local IP address, if
716 not found or bind fails then the remote client will provide
719 Affected files are lib/silcclient/client_ftp.c and
720 lib/silcclient/silcapi.h.
722 * Extended the FILE SEND command to support defining the
723 local IP and port for key exchange listener. They are
724 optional. Affected file irssi/src/silc/core/silc-servers.c.
726 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
728 * Defined to WHOIS command reply the sending of fingerprint
729 of the client's public key (if the proof of posession of the
730 corresponding private key is verified by the server).
731 Updated to the protocol specification.
733 * Added support of receiving the client's public key's
734 fingerprint in command reply in client library. Affected
735 file is lib/silcclient/command_reply.c, and
736 lib/silcclient/idlist.[ch].
738 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
740 * Do not send over 128 chars long nickname to the server
741 in NICK command. Affected file lib/silcclient/command.c.
743 * Do not send over 256 chars long channel names to the server
744 in JOIN command. Affected file lib/silcclient/command.c.
746 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
748 * Assure that silc_server_close_connection cannot be called
749 twice for same socket context. Affected file is
752 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
754 * Send error message to application if opening file for
755 writing during file transfer fails. Affected file is
756 lib/silcclient/client_ftp.c.
758 Remove all file transfer sessions for a client that we're
759 removing from ID cache.
761 Affected file is lib/silcclient/client_ftp.c.
763 * Fixed silc_net_addr2bin to return correct address. Affected
764 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
766 * Fixed file transfer session removing on signoff notify.
767 Affected file irssi/src/silc/core/silc-servers.c.
769 * Added the SilcClientFileError to be returned in the monitor
770 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
771 Affected file lib/silcclient/silcapi.h.
773 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Fixed a crash in silc_client_ftp_free_sessions and
776 silc_client_ftp_session_free_client. Affected file
777 lib/silcclient/client_ftp.c.
779 * Added `disabled' field in the SilcChannelEntry in the server
780 to indicate if the server entry is disabled. Affected file
781 silcd/idlist.h, silcd/command[_reply].c.
783 * SILC server adds now /var/run/silcd.pid everytime it is
784 started. Affected file silcd/silcd.c.
786 * Added silc_server_packet_send_clients to send a packet to
787 the provided table of client entries. Affected file
788 silcd/packet_send.[ch].
790 * Fixed a crash in client resolving in client_prvmsg.c in
791 client library. Affected file lib/silcclient/client_prvmsg.c.
793 * Do not actually remove the client directly from ID cache
794 during SERVER_SIGNOFF, but invalidate it. This way we
795 preserve the WHOWAS info for the client. Affected file
798 * Fixed SERVER_SIGNOFF notify handling in the server. The
799 server is now able to process incoming SERVER_SIGNOFF notify
800 for a server that it doesn't even know about. It will remove
801 the clients provided in the notify. Affected file
802 silcd/packet_receive.c.
804 * Check for partial packet in data queue after every packet that
805 was found from the queue. Return and wait for more data if
806 there is partial data in queue. Affected file is
807 lib/silccore/silcpacket.c.
809 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
811 * Added SilcClietFileError enum to indicate error in
812 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
813 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
814 Affected files lib/silcclient/silcapi.h and
815 lib/silcclient/client_ftp.c.
817 * Check that newsize in silc_buffer_realloc is larger than
818 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
820 * Added better monitor of file transfers. It now monitors
821 key agreement protocol during the file transfer too. Added
822 error reporting too. Affected files
823 irssi/src/silc/core/silc-servers.c,
824 irssi/src/fe-common/silc/module-formats.[ch].
826 * Wrote a help file for FILE command.
828 * Added silc_rng_global_get_byte_fast to get not-so-secure
829 random data as fast as possible. Random data is read from
830 /dev/urandom if available and from the SILC RNG if not
831 available. It is used in padding generation. Affected file
832 lib/silccrypt/silcrng.[ch].
834 * All packets in client library are now processed synchronously.
835 Optimized packet processing a lot. Affected file
836 lib/silcclient/client.c.
838 * All server connection packets are processing synchronously
839 now in server, to optimize packet processing. Affected file
842 * Include files are installed now only in Toolkit distribution
843 if make install is given. Affected files: all Makefile.am's.
845 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Assure that silc_client_notify_by_server_resolve does not
848 resolve the client information multiple times. If it cannot
849 be found by the first it cannot be found at all. Affected
850 file lib/silcclient/client_notify.c.
852 * Fixed WHOWAS command reply calling. Affected file
853 lib/silcclient/command_reply.c.
855 * Removed all references to silc_idlist_get_client from the
856 Irssi SILC client since that call is internal call used by
857 the library. The Irssi SILC client will use now client
858 retrieval functions found in silcapi.h.
860 * Fixed a bug in resolving nickname info before sending
861 private message. It used freed memory. Affected file
862 irssi/src/silc/core/silc-servers.c.
864 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Assure my_channels statistics cannot go negative in server.
867 Affected files silcd/server.c, silcd/server_util.c.
869 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

879 lib/sftp/sftp_fs_memory.c.
881 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Added silc_net_localip to return local host's IP address.
884 Affected file lib/silcutil/silcnet.[ch].
886 * If key exchange or rekey protocol is active for a connection
887 parse all packets syncronously since there might be packets
888 in packet queue that we are not able to process without first
889 processing packets before them. Affected file silcd/server,
890 lib/silcclient/client.c.
892 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
893 whether library should continue processing the packet.
894 Affected file lib/silccore/silcpacket.h.
896 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
897 SilcSFTPMonitorData to SFTP server to monitor various
898 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
899 lib/silcsftp/sftp_server.c.
901 * Added silc_file_size to return file size. Affected file
902 lib/silcutil/silcutil.[ch].
904 * Implemented the file transfer support for the client library.
905 Added preliminary support for simple client to client one-file
906 transmission. Affected file lib/silcclient/client_ftp.c,
907 lib/silccilent/client.[ch].
909 * Added new local command FILE to the Irssi SILC Client.
910 It is used to perform the file transfer. It has subcommands
911 SEND, RECEIVE, SHOW and CLOSE. Affected files
912 irssi/src/silc/core/client_ops.c,
913 irssi/src/silc/core/silc-server.[ch].
915 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Relay the SILC_PACKET_FTP in the server. Affected files
918 silcd/server.c and silcd/packet_receive.c.
920 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
922 * Renamed silc_file_read and silc_file_write to functions
923 silc_file_readfile and silc_file_writefile. Added function
924 silc_file_open and silc_file_close. Affected files
925 lib/silcutil/silcutil.[ch].
927 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Resolve the client info when received private message or
930 channel message for a client which nickname we don't know.
931 Affected files lib/silcclient/client_prvmsg.c and
932 lib/silcclient/client_channel.c.
934 * Do not crash in /KEY if client is not connected. Affected
935 file irssi/src/silc/core/silc-channels.c.
937 * Added SilcClientStatus field to the SilcClientEntry in the
938 lib/silcclient/idlist.h.
940 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
941 is incomplete and is being resolved, it won't be resolved
944 Make sure also that USERS command reply does not resolve
945 twice information. Affected file is
946 lib/silcclient/command_reply.c.
948 Make sure that silc_client_get_clients_by_list does not
949 resolve twice same information.
951 * Check for valid client->id in the silc_server_free_client_data.
952 Affected file silcd/server.c.
954 * Fixed /GETKEY nick@server not to crash if the server entry
955 is not found. Affected file lib/silcclient/command.c.
957 * Fixed the silc_server_check_cmode_rights to check the
958 requested modes correctly. Affected file silcd/command.c.
960 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Better checks for non-printable chars in nick added.
963 Affected file silcd/command.c.
965 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Call the silc_server_udpate_servers_by_server in the
968 primary router that comes back online in the backup resuming
969 protocol. Otherwise it routes packets wrong. Affected file
970 silcd/server_util.[ch], silcd/server_backup.c.
972 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
974 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
975 lib/silcutil/silcbuffmt.[ch].
977 * Redefined the SILC packet header to include the padding
978 length. Affected file lib/silccore/silcpacket.[ch].
980 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
981 length for maximum padding up to 128 bytes). Affected
982 file lib/silccore/silcpacket.h.
984 * Removed all backwards support for old 0.5.x MAC thingies.
985 The SILC packet header change makes it impossible to be
986 backwards compatible.
988 * Send the ENDING packet with timeout in the backup resuming
989 protocol. This is to assure that all routers has connected
990 to the primary router. Affected file silcd/server_backup.c.
992 * Changed the RNG to take the first IV from random data. It
993 used to take it from zero actually. Changed the RNG also
994 to use /dev/urandom during session. /dev/random is used
995 in initialization. Affected file lib/silccrypt/silcrng.[ch].
997 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Changed the SILC packet header to have the first two bytes
1000 (the packet length) encrypted. Affected files aroung the
1001 code tree, lib/silccore/silcpacket.[ch]. Removed the
1002 SilcPacketCheckDecrypt callback. It is not needed anymore
1003 since the silc_packet_receive_process will determine now
1004 whether the packet is normal or special.
1006 * Implemented the unidirectional MAC keys. Affected files
1007 lib/silcske/silcske.c, silcd/protocol.c and
1008 lib/silcclient/protocol.c.
1010 * Implemented the packet sequence number to the MAC computation.

1012 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1013 lib/silcclient/protocol.c.
1015 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Allow backup router to announce servers. All servers
1018 announced by backup router are added to the global list
1019 automatically. Update hte server's socket to our primary
1020 router also when backup router announces a server.
1021 Affected file silcd/packet_receive.c.
1023 * Do not update the client->router in the function
1024 silc_server_udpate_clients_by_server if the client is on
1025 global list. We might fail to find any specific server
1026 for locally connected clients and local cell clients. They
1027 should still use the `from' and not `to' as client->router.
1028 This fixes backup router resuming protocol. Affected file
1029 silcd/server_util.c.
1031 * Decrease channel statistics count only if the channel
1032 deletion worked. Affected files are silcd/server.c and
1033 silcd/server_util.c.
1035 * Added silc_server_update_servers_by_server to update origin
1036 of all server entries. Used during backup router protocol.
1037 Affected files silcd/server_util.[ch], silcd/server.c. and
1038 silcd/backup_router.c.
1040 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1041 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1042 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1043 lib/silccrypt/silchmac.c.
1045 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Assure that router cannot reroute the same channel message
1048 to the sender. Affected file silcd/packet_receive.c.
1050 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Made better checks that the channel message is not sent
1053 to the router it came from. Affected file is
1054 silcd/packet_send.c. Fixed memory leak too.
1056 * Announce informations for incoming router connection, but
1057 only after checking if it is replaced by backup router.
1058 Affected file silcd/packet_receive.c.
1060 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Fixed the backup resuming protocol to work in multiple
1063 router environment. Affected file silcd/server_backup.c.
1065 * Route packet only to one router in the function
1066 silc_server_packet_send_to_channel. Affected file is
1067 silcd/packet_send.c.
1069 * Fixed silc_server_send_notify_dest to set the broadcast
1070 flag. Fixed the silc_server_send_notify_topic to actually
1071 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1072 Affected file silcd/packet_send.c.
1074 * Changed the SFTP Filesystem interface. Changed the
1075 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1076 the filesystem operation function. The SilcSFTPFilesystem
1077 is now a context that is allocated by all filesystem allocation
1078 functions and it already includes the operations structure
1079 and filesystem specific context. It is given as argument
1080 now to the silc_sftp_server_start. This made the interface
1081 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1082 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1084 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Changed the backup router adding and getting interfaces
1087 in the server. The router that will be replaced by the
1088 specified backup router is now sent as argument. Affected
1089 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1092 * Added silc_net_addr2bin_ne to return the binary form of
1093 the IP address in network byte order. Affected files
1094 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1096 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Check for existing server ID in silc_server_new_server
1099 and in silc_server_connect_to_router_final and remove the
1100 old entry if it exists. Affected file silcd/packet_receive.c,
1103 * Send the channel message always to only one router, either
1104 in upstream or downstream. Affected file is
1105 silcd/packet_send.c.
1107 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Wrote the definition of the backup resuming protocol to the
1110 protocol specification.
1112 * Removed one redundant channel key generation from normal
1113 server during joining procedure. Removed one redundant
1114 channel key sending from server to router during joining
1115 procedure. Affected file silcd/command.c.
1117 * Made minor bugfixes to the backup router resuming protocol.
1118 Affected file silcd/server_backup.c, server.c.
1120 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Added --disable-asm configuration option. Affected files
1123 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1126 * Implemented the backup resuming protocol that is used to
1127 resume the primary router position in the cell after the
1128 primary router comes back online. Affected files
1129 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1130 and silcd/server_util.[ch].
1132 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Sleep two (2) seconds after sending QUIT command to server.
1135 Affected file lib/silcclient/command.c.
1137 * Assure that if outgoing data buffer is pending do not force
1138 send any data. Affected file silcd/packet_send.c.
1140 * Assure that if outgoing data buffer is pending do not force
1141 send any data. Affected file lib/silcclient/client.c.
1143 * Implemented the backup router support when the primary router
1144 goes down. The servers and routers can now use the backup
1145 router as new primary router without loosing connectivity.
1147 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1150 in the server to indicate disabled entry. All data read
1151 from the connection will be ignored and no data is sent
1152 for entry that is disabled. Affected files are
1153 silcd/idlist.h, silcd/server.c.
1155 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Created SFTP client and server test programs in the
1158 lib/silcsftp/tests directory.
1160 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Implemented memory filesystem (virtual filesystem) for
1163 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1166 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Implemented the SFTP (SSH File Transfer Protocol) to the
1169 lib/silcsftp. It includes SFTP client and SFTP server
1172 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Moved lib/silccore/silcprotocol.[ch] to the
1175 lib/silcutil library.
1177 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1178 take variable argument list pointer as argument. Affected
1179 file lib/silcutil/silcbuffmt.[ch].
1181 * Added silc_buffer_set function that is used to set data
1182 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1183 Affected file lib/silcutil/silcbuffer.h.
1185 * Changed various routines in the core library to use the new
1186 silc_buffer_set instead of allocating new buffer only for
1189 * Added 64-bit value formatting and unformatting support to the
1190 silc_buffer_[un]format routines. Affected file is
1191 lib/silcutil/silcbuffmt.[ch].
1193 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1194 to includes/bitmove.h.
1196 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1198 * Fixed channel user mode saving in client library. Affected
1199 file lib/silcclient/command[_reply].c.
1201 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Defined the file transfer to the SILC Protocol. Added
1204 new packet type SILC_PACKET_FTP and defined File Transfer
1205 Payload. The mandatory file transfer protocol is SFTP
1206 (SSH File Transfer Protocol). Affected file in addition
1207 of the internet draft is lib/silccore/silcpacket.h.
1209 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1210 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1211 is used as part of backup router protocol when the primary
1212 router of the cell is back online and wishes to resume
1213 the position as primary router.
1215 * Redefined the MAC generation keys in the protocol. The
1216 same key is not used anymore in both direction. Both
1217 direction will now use different keys for sending and
1218 receiving. This fixes a potential security flaw. This
1219 change causes incompatibilities in the protocol.
1221 * Redefined also the MAC computation from the packet.
1222 An packet sequence number is now added to the MAC
1223 computation. This prevents possible replay attacks against
1224 the protocol. This change too causes incompatibilities
1227 Added `sequence' field to the SilcPacketContext to hold
1228 the current sequence number for the packet.
1230 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Added `created' field to the SilcIDListData in the file
1233 silcd/idlist.h to indicate the time when the entry was
1236 * Added `created' field to the SilcChannelEntry too. Affected
1237 file silcd/idlist.h.
1239 * Added `creation_time' aguments to all the announcement functions
1240 in the server. If it is provided then only the entries that
1241 was created after the provided time frame are actually
1242 announced. Affected file silcd/server.[ch].
1244 * The protocol says that the Channel ID's IP address must be
1245 based on the router's IP address. Added check for this in
1246 the silc_server_new_channel when processing incoming New Channel
1247 Payload. Affected file silcd/packet_receive.c.
1249 * Print out the correct version with --version in SILC client.
1250 Affected file irssi/src/silc/core/silc-core.c.
1252 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1254 * Fixed WHOWAS command to check for completnes of the client
1255 entry always, not just when the command is coming from client.
1256 Affected file silcd/command.c.
1258 * Added new function silc_server_packet_queue_purge to purge the
1259 outgoing data queue to the network. After the function returns
1260 it is guaranteed that the outgoing packet queue is empty.
1261 Affected file silcd/packet_send.[ch].
1263 * Purge the outgoing packet queue in the rekey protocol's final
1264 callback to assure that all rekey packets go to the network
1265 before quitting the protocol. Affected file silcd/server.c.
1267 * Added silc_client_packet_queue_parse as similar function as
1268 in server to the client library. The affected file is
1269 lib/silcclient/client.c.
1271 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Splitted silcd/server.c and created silcd/server_util.[ch]
1274 for utility functions.
1276 * Added new socket flag SILC_SF_DISABLED to indicate that the
1277 connection is open but nothing can be sent to or received from
1278 the connection. Affected file lib/silcutil/silsockconn.[ch].
1279 The checking for disabled socket is checked in the low level
1280 silc_socket_write and silc_socket_read functions.
1282 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Allow only nicknames and channel names that fits into the
1285 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1287 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * When processing JOIN command reply in server check that if
1290 the channel exists in our global list we'll move it the local
1291 list. Affected file silcd/command_reply.c.
1293 * Fixed the check whether client is joined on the channel already
1294 in JOIN command. Affected file lib/silcclient/command.c.
1296 * Fixed the JOIN command reply to check whether the channel
1297 already exists. Affected file lib/silcclient/command_reply.c.
1299 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Added silc_ske_status_string to map the SKE error numbers
1302 to readable strings. The affected files are
1303 lib/silcske/silcske[_status].[ch].
1305 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Do not show the private channels on the WHOIS channel list
1308 as it is not allowed by the protocol. The affected file is
1311 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Assure that the packet length digged from the actual packet
1314 is something sensible in the silc_packet_decrypt_rest_special
1315 in lib/silccrypt/silcpacket.c.
1317 * Free and NULL the allocated pointer in silc_hmac_alloc if
1318 the HMAC allocation fails. The affected file is
1319 lib/silccrypt/silchmac.c.
1321 * Print the selected security properties to the log files in
1322 the server. Affected file silcd/protocol.c.
1324 * Add SKE's reference counter even if calling the completion
1325 callback manually. Otherwise it goes negative, although it
1326 does not cause any problems. The affected file is
1327 lib/silcske/silcske.c.
1329 * Remove the client entry with short timeout after giving the
1330 KILL command. Affected file lib/silcclient/command.c.
1332 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1333 case all found clients are already disconnected (WHOWAS would
1334 found them) in the server. Affected file silcd/command.c.
1336 * Update the last_receive (time of last data received) to be
1337 updated only when received private or channel message so that
1338 the idle time showed in WHOIS makes more sense.
1340 * Added boolean field `valid' in to the SilcClientEntry in the
1341 client library to indicate whether the entry is valid or not.
1342 This fixes the nickname change bug on channel when changing
1343 the nickname to be same than the old (like nick to Nick) the
1344 nickname formatter doesn't set the new nick anymore to Nick@host.
1345 Affected file lib/silcclient/idlist.[ch].
1347 * Now actually fixed the nickname changing on disconnection.
1348 Added new function silc_change_nick to the Irssi SILC Client.
1349 Affected file irssi/src/silc/core/client_ops.c,
1350 irssi/src/silc/core/silc-nicklist.[ch].
1352 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Check that the public key exists in the GETKEY command before
1355 trying to encode it. Affected file silcd/command.c.
1357 * Print some notifications on received public keys with GETKEY
1358 command in the Irssi SILC Client. Affected files are
1359 irssi/src/fe-common/silc/module-formats.[ch],
1360 irssi/src/silc/core/client_ops.c.
1362 * Use IDENTIFY command to resolve the server information in the
1363 GETKEY command instead of INFO command. Affected file
1364 lib/silcclient/command.c.
1366 * All command reply functions in the client library now calls
1367 the pending command reply callbacks even if an error has
1368 occurred. The server has done this a long time and now it was
1369 time to move the client library to this as well. Now all
1370 errors can be delivered back to the pending command reply
1371 callbacks if necessary. Affected files are
1372 lib/silcclient/command[_reply].[ch].
1374 * Change the nickname on disconnection back to the username
1375 because in reconnect the server will enforce it to it anyway.
1376 Affected file irssi/src/silc/core/silc-servers.c.
1378 * Fixed a config file parsing bug in the Irssi SILC client.
1379 Affected file irssi/src/silc/core/clientconfig.c.
1381 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * When printing the channel mode on JOIN, verify that the
1384 channel key and channel's HMAC are valid. Affected file
1385 irssi/src/silc/core/client_ops.c.
1387 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1390 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1391 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1393 * Removed channel key rekey task deleting from the function
1394 silc_server_save_channel_key. Affected file silcd/server.c.
1395 Added explicit timeout task context instead that is used to
1396 delete the task if we are registering a new task before the
1397 new task has elapsed.
1399 * When channel key rekey occurs the client library now saves
1400 the old channel key for a short period of time (10 seconds) and
1401 is able to use it in case some is still sending channel
1402 messages encrypted with the old key after the rekey. Affected
1403 file lib/silcclient/[idlist.h|client_channel.c].
1405 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Added check to the silc_server_new_id_real to not accept
1408 new ID if it is the sender's own ID. Affected file is
1409 silcd/packet_receive.c.
1411 * Assure that we do not announce ourself or the one we've
1412 sending our announcements when we're router and are announcing
1413 servers to our primary router. Affected file silcd/server.c.
1415 * Fixed silc_server_command_identify_check_client to assemble
1416 correct WHOIS packet. It send corrupted WHOIS packet and
1417 caused problem with router to router connections. Affected
1418 file silcd/command.c.
1420 Fixed also silc_server_command_whois_check the same way
1421 as for the IDENTIFY command.
1423 * Added new SilcIDListStatus to the server in the SilcIDListData
1424 structure. The status now includes the current status of
1425 the entry (like registered, resolved etc.). Affected file
1426 silcd/idlist.[ch]. Defined a bunch of different status types
1427 as well. This replaced the old boolean registered field as well.
1429 Added resolve_cmd_ident field to the SilcClientEntry structure
1430 too so that if the entry is for example being resolved so
1431 another command may attach to the same pending command reply
1432 without requiring to resolve the same entry again. This concept
1433 should optimize the WHOIS and the IDENTIFY resolving under
1434 heavy load by taking away unnecessary resolving for entries
1435 that are being resolved already.
1437 Added support for adding multiple pending commands for one
1438 command idenfier. Affected file silcd/command[_reply].[ch].
1440 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1441 before deleting the data. Otherwise the hash table will have
1442 freed data in comparison functions. Affected file is
1443 silcd/command_reply.c.
1445 * Fixed silc_idlist_replace_client_id to add the new entry to
1446 the cache with NULL nickname. Otherwise there will be invalid
1447 memory as the nickname after the nickname is freed. Affected
1448 file silcd/packet_receive.c.
1450 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1451 saved into wrong slots because the previous number of entries
1452 was not taken into account. Affected file silcd/idlist.c.
1453 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1455 * If we are router and we receive JOIN notify to a channel that
1456 does not have any users then notified client is marked as the
1457 channel founder, as it is it. The affected file is
1458 silcd/packet_receive.c
1460 * Added to the extended hash table API's table_del_*ext functions
1461 the destructor as argument too, so that the caller can decide
1462 which destructor to use or whether to use destructor at all.
1463 Affected file lib/silcutil/silchashtable.[ch].
1465 * Fixed ID Cache purging. It actually deleted the entries from
1466 the hash table after the data was freed. The hash table ended
1467 up comparing freed memory. The affected file is
1468 lib/silccore/silcidcache.c.
1470 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Fixed Irssi SILC client's KILL command's HELP syntax.
1474 * The USERS command now resolves the detailed user information
1475 if the userinfo field is missing. Affected file is
1476 lib/silcclient/command_reply.c.
1478 * Do not print error in silc_file_read if the read file does
1479 not exist. Just silently return NULL. Affected file is
1480 lib/silcutil/silcutil.c.
1482 * Fixed the silc_log_output to not wine about NULL filename
1483 and to not create some bogus " " filename. Affected file is
1484 lib/silcutil/silclog.c.
1486 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Fixed various printing bugs on the user interface in the
1489 Irssi SILC Client. Minor changes that were forgotten from
1492 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * Fixed the configure.in.pre and the compilation and distribution
1495 environment to support the new autoconf 2.52. That version is
1496 now required to compile the CVS trunk.
1498 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1501 to generally parse user@fqdn format strings. Affected file
1502 lib/silcutil/silcutil.c.
1504 * Added nickname_format and nickname_force_format fields to the
1505 SilcClientParams structure. The first one defines the format
1506 for the nicknames that the library will enforce if the receives
1507 multiple same nicknames. The second one is boolean value and
1508 can be used to force the library to always enforce the format
1509 to the nicknames regardles whether there are multiple nicknames
1510 or not. This configurable formatting was employed to flexibly
1511 support accessing multiple nicknames from the user interface.
1512 The userinterface can now set the nicknames to what ever format
1513 they prefer. Affected file lib/silcclient/silcapi.h.
1515 Added function silc_client_nickname_format to the file
1516 lib/silcclient/idlist.c. It performs the nickname formatting.
1518 Added new field `hostname´ to the SilcClientEntry context.
1519 It holds the hostname of the client. Affected file is
1520 lib/silcclient/idlist.h.
1522 * Irssi SILC Client sets the nicknames in nick@hostn format.
1523 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1524 irssi/src/silc/core/silc-core.c.
1526 The WHOIS printing now also shows both the real nickname and
1527 the formatted nickname so that user knows how to access the
1528 user if there are multiple same nicknames cached. Affected
1529 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1530 printing formatting too to take the hostname now as a separate
1531 argument. The Affected file is
1532 irssi/src/fe-common/silc/modules-formats.[ch].
1534 * Changed the silc_client_get_clients_local to accept the formatted
1535 nickname as argument. It accepts the real nickname too but the
1536 formatted nickname can be used to find the true entry from
1537 multiple entries. Affected file lib/silcclient/silcapi.h and
1538 lib/silcclient/idlist.c.
1540 * Added nickname_format_parse field to the SilcClientParams.
1541 It is a callback function provided by the application to parse
1542 the nickname out of the formatted nickname string. The library
1543 calls it to get the nickname from the formatted string. Since
1544 the application generally knows better the format of the nickname
1545 string it parses it instead of the library, even though library
1546 encodes the formatted string. If the callback function is not
1547 provided then the library will use the string as is. The
1548 affected file is lib/silcclient/silcapi.h.
1550 * All the nickname strings passed to the client library in
1551 commands are now expected to be formatted nickname strings.
1552 If the command does not support the formatted nickname string
1553 it will assume that the sent string is the actual nickname.
1554 Affected file lib/silcclient/command.c.
1556 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1558 * Added public key authentication support to OPER and SILCOPER
1559 commands in the client library. Affected file is
1560 lib/silcclient/command.c.
1562 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Changed the get_auth_methdod client operation to be asynchronous.
1565 It can be async if the application resolves the authentication
1566 method from the server during the negotiation. Added new
1567 SilcGetAuthMeth completion callback that the application will
1568 call after resolving the authentication method.
1570 Added function silc_client_request_authentication_method that
1571 the application can use to resolve the authentication method
1572 from the server. Added also SilcConnectionAuthRequest callback
1573 that the library will call after the server has replied. The
1574 application can call this function if it does not know the
1575 current authentication method.
1577 Affected files are lib/silcclient/client.c and
1578 lib/silcclient/silcapi.h.
1580 * The Irssi SILC client now automatically resolves the authentication
1581 method incase any configuration information is not present (and
1582 currently there never is). The affected file is
1583 irssi/src/silc/core/client_ops.c.
1585 * Fixed public key authentication from the client library.
1586 Affected file lib/silcclient/protocol.c. Changed also the
1587 protocol specification about the public key authentication in
1588 the connection authentication protocol. The actual data to be
1589 signed is now computed with a hash function before signing.
1591 * Fixed the public key authentication from the server as well.
1592 Affected file silcd/protocol.c.
1594 * Removed the mlock()'s from the memory allocation routines.
1595 Affected file lib/silcutil/silcmemory.c. The ./configure does
1596 not check anymore for the mlock(). Affected file is
1599 * Fixed USERS command in server to allow the execution of the
1600 command for private and secret channels if the client sending
1601 the command is on the channel. Affected file silcd/command.c.
1603 * Fixed silc_client_get_clients_local to return the clients
1604 count correctly. It could return wrong value. Affected file
1605 lib/silcclient/idlist.c.
1607 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1610 types. The assembler optimizations seemed not to like 64-bit
1611 data types. The assmebler optimizations thus are now enabled
1612 also for BSD systems as opposed to only enable them for Linux.
1614 * Do not check for threads at all on BSD systems. Affected
1615 file configure.in.pre.
1617 * Removed -n and -h options from the Irssi SILC Client since
1618 they are not used in silc.
1620 * Fixed the prime generation to assure that the first digit
1621 of the generated random number is not zero since our conversion
1622 routines does not like number strings that starts with zero
1623 digit. If zero digit is seen the random number is regenerated.
1624 This caused some corrupted RSA keys when the zero first digit
1625 was met. Affected file lib/silcmath/silcprimegen.c.
1627 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Fixed WIN32 configuration in the ./configure script.
1630 Fixed to include xti.h on environments that has it.
1631 Patches by Carsten Ilchmann and andrew.
1633 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Changed the silc_id_create_client_id to be collision
1636 resistant. It is now assured that there cannot be created
1637 two same client ID's. I suspect that some weird bugs in
1638 the server were actually caused by duplicate Client IDs.
1639 Affected file silcd/serverid.[ch]. A router receiving
1640 new ID now also assures and informs the sending server
1641 if the ID caused collision.
1643 * Changed the silc_id_create_channel_id to also assure that
1644 there are no collisions.
1646 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Statement about ignoring the Mutual Authentication flag when
1649 performing rekey with PFS was a bit misleading. It is ignored
1650 if it was set in the initial negotiation, it cannot be even
1651 set in the rekey. Fixed in the ke-auth draft. Started the
1652 new versions of the protocol drafts in the doc/.
1654 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Fixed a bug in silc_client_command_identify_save when saving
1657 new channel information. The channel name was no duplicated
1658 and caused crash on exit. Affected file is
1659 lib/silcclient/command_reply.c.
1661 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Fixed the getkey command handling in the server. Send just
1664 empty OK reply to the sender if the key could not be fetched
1665 (but everything else was ok, like the key just was not available).
1666 Changed the public key parameter to optional in the protocol
1667 specs so that empty OK reply can be sent. Affected file
1670 Added a message to Irssi SILC client to tell to user if the
1671 server did not return a public key.
1673 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Fixed a channel key regeneration bug. It registered new
1676 timeout tasks exponentially until all system resources were
1677 used. Affected file silcd/server.c.
1679 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1681 * Added the SILC Document generator to the scripts/silcdoc.
1682 It can be used to generate the Toolkit Reference Manual out
1683 of the source tree. Internally it will also use the RoboDoc
1684 generator now imported in util/robodoc.
1686 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Added couple of return's in rekey protocol if error orccurred
1689 during the protocol. The execution must be terminated.
1690 Affected file silcd/protocol.c. Also, terminate the protocol
1691 always with timeout.
1693 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * The client's Client ID was created initally from the wrong
1696 nickname (it could have been in format nick@host) in the
1697 silc_server_new_client. Affected file silcd/packet_receive.c
1699 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Added some SILC_LOG_ERROR's to various error conditions
1702 if client could not be added to ID cache. Affected files
1703 silcd/packet_receive.c and silcd/server.c.
1705 * When client's sock->user_data is freed, NULL also the
1706 client->router and client->connection pointers. Added check
1707 for these pointers being NULL to various places around the
1708 code. Affected file silcd/server.c.
1710 * Added client->data.registered == TRUE checks to various
1711 places around the code to assure that unregistered client's
1712 are not handled when it is not allowed. Affected file
1715 * Added `bool registered' fields to all
1716 silc_idlist_[server|client]_get_* routines to indicate whether
1717 the fetched client needs to be registered or not. Affected
1718 file silcd/idlist.[ch].
1720 * Add your own entry as registered to the ID cache in the
1721 server. Affected file server.c.
1723 * Fixed a bug in silc_server_new_server. The SilcServer was
1724 set as the new server's context instead of SilcServerEntry.
1725 This naturally caused some weird bugs.
1727 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Do not delete the channel rekey task when adding it
1730 for in silc_server_create_channel_key.
1732 * Changed the silc_server_create_channel_key to return
1733 TRUE or FALSE to indicate the success of the channel key
1736 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Fixed MSVC++ project files and added missing files to
1739 Makefiles under win32/.
1741 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Do not add TCP_NODELAY flag if the operating system
1744 does not have it defined. Affected files are
1745 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1747 * Fixed buffer overflow from Irssi SILC Client. Affected
1748 file irssi/src/fe-common/core/themes.c.
1750 * Fixed double free in client library in the file
1751 lib/silcclient/client.c when disconnecting from server.
1753 * Applied double free patch from cras to Irssi SILC client.
1754 Affected files irssi/src/core/[modules/expandos].c
1756 * Fixed the disconnection handling to Irssi SILC Client.
1757 The application must call silc_client_close_connection
1758 in ops->connect client operation in case of failure of
1759 the connection. Affected file is
1760 irssi/src/silc/core/client_ops.c.
1762 * Do not set sock->protocol to NULL in the function
1763 silc_client_close_connection after executing the protocol's
1764 final callback since the sock might not be valid anymore.
1765 Affected file lib/silcclient/client.c.
1767 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Do not enable SILC_THREADS if the linking with libpthread
1770 did not happen. Affected file configure.in.pre.
1772 * Added notion to protocol specification that server must
1773 verify the sent authentication payload with CMODE when
1774 setting the channel founder key. Implemented it to the
1775 server. Affected file silcd/command.c.
1777 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1779 * Added _EXTRA_DIST SILC distribution variable to the
1780 distributions file. It is used to conditionally add extra
1781 files or directories to the specific distribution. Affected
1782 files ./prepare, Makefile.am.pre and distributions.
1784 Removed the `_' from the start of the distribution names.
1787 * Added README.WIN32 for instructions to compile the Toolkit
1790 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Fixed a double free in disconnection in the server. Affected
1793 file is silcd/server.c.
1795 * Fixed the lib/silcske/groups.c to work now also with GMP
1796 MP library. The string conversion did not work when using
1797 specific base and the base is indicated in the string as well.
1799 * Created win32/ directory which now includes MSVC++ specific
1800 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1801 It will appear only in the toolkit distribution
1803 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Changed the key material distribution function in case when
1806 the hash output is too short. The data is now concatenated
1807 a bit differently than it used to. Made the change to the
1808 SKE protocol specification.
1810 * Added better GMP detection to configure.in.pre. A patch
1813 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1815 * Fixed a minor bug in SKE that might cause some problem on
1816 some platforms. Affected file lib/silcske/silcske.c.
1818 * Added the cookie checking for initiator in the SKE. It checks
1819 that the responder returns the sent cookie unmodified. The
1820 affected file is lib/silcske/silcske.c. Added new SKE
1821 error type INVALID_COOKIE that can be sent during the
1822 negotiation. Fixed some memory leaks as well.
1824 * Added the "invalid cookie" error message to Irssi SILC client's
1827 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Added `task_max' field to the SilcClientParams to indicate
1830 the maximum tasks the scheduler can handle. If set to zero,
1831 default values are used. Affected file lib/silcclient/silcapi.h.
1833 * Fixed memory leaks in silc_client_close_connection. Affected
1834 file lib/silcclient/client.c.
1836 * Added silc_client_del_client_entry to client library to free
1837 all memory of given client entry. Affected file is
1838 lib/silcclient/idlist.[ch].
1840 * Added new functions silc_client_del_channel and
1841 silc_client_del_server to delete channel and server entries.
1842 Affected file lib/silcclient/[silcapi.h/idlist.c].
1844 * Removed silc_client_del_client_by_id from silcapi.h.
1846 * Fixed the INFO command to return the server's own info
1847 correctly when querying by Server ID. Affected file is
1850 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Removed the non-blocking settings in WIN32 code in the
1853 silc_sock_[read/write] and added SleepEx instead. Affected
1854 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1855 of input data is now checked with FIONREAD and ioctlsocket.
1857 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Call silc_schedule_task_del_by_context in the
1860 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1861 Affected file lib/silccore/silcprotocol.c.
1863 * Call silc_protocol_cancel for active protocols in the
1864 silc_server_close_connection if the funtion
1865 silc_server_free_sock_user_data has not been called.
1866 Affected file silcd/server.c.
1868 * Generic tasks cannot be deleted using the del_by_fd
1869 task deleting function since generic tasks does not match
1870 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1872 * Added a notion to SILCOPER help file that the SILCOPER works
1873 only on router server, not on normal server.
1875 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1877 * Added for WIN32 support for the new scheduler as well.
1878 Affected file lib/silcutil/win32/silcwin32schedule.c.
1880 * Fixed the SHA1 implementation to work on various platforms.
1882 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1885 API. It is part of the scheduler now. Everything else is
1886 as previously but some functions has changed their names.
1887 Checkout the lib/silcutil/silcschedule.h for the interface.
1888 Updated all applications to use the new interface. Affected
1889 files are lib/silcutil/silcschedule.[ch].
1891 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Found a bug in the SKE implementation. The HASH value,
1894 specified by the protocol, was not computed correctly. The
1895 public key of the responder was not added to the computation
1896 even though it is mandatory. Affected file lib/silcske/silcske.c.
1897 This unfortunately causes incompatibilities with older
1898 clients and servers.
1900 * Added WIN32 specific network init and uninit functions:
1901 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1902 the Winsock2. Affected file lib/silcutil/silcnet.h and
1903 lib/silcutil/win32/silcwin32net.c.
1905 * Set the socket always to nonblocking mode on WIN32 after
1906 reading data or writing data. Affected file is
1907 lib/silcutil/win32/silcwin32sockconn.c.
1909 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Fixed various compilation problems under WIN32. Affected
1912 files lib/silcutil/win32/silcwin32thread.c and
1913 lib/silcutil/win32/silcwin32schedule.c.
1915 * Removed all _internal.h #includes from public header
1916 files. Internal headers must never be included from
1919 Removed also the lib/silcske/payload_internal.h file.
1921 * All include files that may be needed (public and some others
1922 included by the public headers) by application developers are
1923 now copied to the ./includes directory. It does not copy any
1924 internal headers. Affected file Makefile.defines.pre and all
1925 Makefile.am's under lib/ and subdirs.
1927 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Do not change the ~/.silc directory's permissions automatically.
1930 Affected file irssi/src/silc/core/clientutil.c.
1932 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Do not cancel the protocol in silc_server_close_connection
1935 it might cause recursion. Now cancelled in the function
1936 silc_server_free_sock_user_data. Affected file silcd/server.c.
1938 * Fixed the silc_server_remove_clients_by_server to regenerate
1939 the channel keys correctly finally. Added also new function
1940 silc_server_remove_clients_channels to actually do it.
1941 Affected file silcd/server.c.
1943 * Fixed the silc_server_new_channel to not crash by giving
1944 wrong router to the new channel. Affected file is
1945 silcd/packet_receive.c.
1947 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1950 which is given as argument to the silc_client_alloc now.
1951 It can be used to configure the client and set various parameters
1952 that affect the function of the client.
1954 * The USERS command in server did not check whether the channel
1955 is private or secret. Affected file silcd/command.c.
1957 * Added new argument to the USERS command in protocol specification.
1958 The USERS command now can take the channel name as argument
1959 as well. Added support for this in client and server and
1960 updated the protocol specs.
1962 * Completed the GETKEY command in client. It can be now used
1963 to fetch also servers public key not only some clients.
1964 Affected files lib/silcclient/command[_reply].c.
1966 * Added silc_client_get_server to return server entry by the
1967 server name. Affected files lib/silcclient/silcapi.h and
1970 * Redefined the IDENTIFY command in protocol specification to be
1971 more generic. It now can be used to query information about
1972 any entity in the SILC Network, including clients, servers and
1973 channels. The query may be based either the entity's name
1974 or the ID. Added support for this in both client and server.
1976 Affected files silcd/command.c and lib/silcclient/command.c
1977 and command_reply.c.
1979 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1980 the _from_client and _from_server functions. Affected file
1983 * Added silc_client_get_channel_by_id_resolve to the file
1984 lib/silcclient/silcapi.h to resolve channel information by
1985 its ID. Added also silc_client_get_channel_by_id that
1986 does not resolve it from the server.
1988 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Added SilcServerEntry context into the client library
1991 to represent one server. The INFO command now allocates
1992 these to save the resolved server info. For now on the
1993 client library will also keep information about servers,
1994 connected and resolved with INFO.
1996 The INFO command now allocates the SilcServerEntry context
1997 and saves the server info there. The COMMAND_REPLY in
1998 the INFO now returns the parameters to application in
1999 same order as defined in the protocol specification.
2001 The entries are cached in the client->server_cache.
2003 * The INFO command is now issued after received the Client ID
2004 from the server. Affected file lib/silcclient/client.c.
2006 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2007 to the application as the mode changer might be server.
2008 It is guaranteed that NULL is not returned anymore to the
2009 application. Affected file lib/silcclient/client_notify.c.
2011 The ID Type is now also passed to the application so that
2012 it can check whether the returned entry is SilcClientEntry
2015 Added new function silc_client_get_server_by_id to return
2016 the server entry by ID. Affected files are the
2017 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2019 * Do not create the channel in the Irssi SILC Client when issuing
2020 the JOIN command but when received the sucessful JOIN command
2021 reply. Otherwise the channel might get created even though we
2022 could not join it. The Affected file is
2023 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2025 * Fixed a channel joining bug in router. The router must also
2026 check the channel modes, invite and ban lists etc. when serving
2027 the JOIN command sent by normal server. Affected file is
2028 silcd/command.c. The router now resolves the client's
2029 information from the server who sent the JOIN command if it
2030 does not know it, and processes the JOIN command only after
2033 * Changed the SilcCommandCb to take new argument; void *context2.
2034 Affected file lib/silccore/silccommand.h
2036 The second argument in the command callbacks in the server now
2037 includes the SilcServerCommandReplyContext if the command was
2038 called as pending command callback from the command reply.
2039 Otherwise it is NULL. When called as pending the status of the
2040 command reply will be checked and if it was erronous the
2041 error will be sent to the original sender of the command.
2042 This way the client always receives the error messages even
2043 though the server was actually the one who received the error
2044 when it resent the command to router, for example. Affected
2045 files silcd/command[_reply].[ch].
2047 * Fixed sending WHOWAS command's error message to client if
2048 the requested client could not be found. It was missing.
2051 * Changed the CMODE and CUMODE commands reply arguments in the
2052 protocol specification. The Channel ID is now sent in both
2053 of the commands to identify the channel. Implemented this
2054 new feature to the client and server. Affected files
2055 lib/silcclient/command_reply.c and silcd/command.c.
2057 * Made better checks for invite and ban lists in the JOIN
2058 command in server. Affected file silcd/command.c.
2060 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * The server now performs the incoming host IP/DNS lookup
2063 using the silc_socket_host_lookup and thus does not block
2064 the server anymore. Affected file silcd/server.c.
2066 * Completed the multi-thread support for SILC Scheduler in
2067 the lib/silcutil/silcschedule.c.
2069 * Fixed the configure.in.pre to detect the pthread correctly
2072 * Fixed a deadlock in silc_task_queue_wakeup in the file
2073 lib/silcutil/silctask.c.
2075 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Added new function silc_schedule_wakeup that is used in
2078 multi-threaded environment to wakeup the main thread's
2079 schduler. It needs to be used when a thread adds a new task
2080 or removes a task from task queues. After waking up, the
2081 scheduler will detect the task queue changes. If threads
2082 support is not compiled in this function has no effect.
2083 Implemented the wakeup mechanism to both Unix and WIN32
2084 systems. Affected files are lib/silcutil/silcschedule.[ch],
2085 lib/silcutil/unix/silcunixschedule.c and the
2086 lib/silcutil/win32/silcwin32schedule.c.
2088 * Added new function silc_task_queue_wakeup to wakeup the
2089 scheduler by the specified task queue. Affected file
2090 lib/silcutil/silctask.[ch].
2092 * The silc_socket_host_lookup_start now wakes up the scheduler
2093 after adding the timeout task. Affected file is
2094 lib/silcutil/silcsockconn.c.
2096 * The silc_socket_host_lookup is synchronous now if the threads
2097 support is not compiled in. However, the callback is still
2098 called asyncronously through the scheduler, anyway. Affected
2099 file lib/silcutil/silcsockconn.c.
2101 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Added new function silc_socket_host_lookup to perform
2104 asynchronous IP and FQDN lookups for the socket connection.
2105 Affected files lib/silcutil/silcsockconn.[ch].
2107 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2110 that may or may not compile the mutex support in.
2112 Changed the silc_mutex_alloc interface. It allocates the
2113 mutex now to the sent pointer and returns TRUE or FALSE.
2115 Affected file lib/silcutil/silcmutex.h.
2117 * Wrote the SILC Task Queue interface to support multi-threads.
2118 Affected file lib/silcutil/silctask.[ch].
2120 * Wrote the SILC Scheduler to support multi-threads. Affected
2121 file lib/silcutil/silcschedule.c.
2123 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2126 in lib/silcutil/win32/.
2128 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Defined SILC Mutex API and SILC Thread API and implemented
2131 them for Unix. Affected files are
2132 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2133 lib/silcutil/unix/silcunixmutex.c and
2134 lib/silcutil/unix/silcunixthread.c.
2136 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Fixed the silc_server_remove_clients_by_server's channel
2139 key re-generation. The hash table handling was incorrect
2140 and would not work with many channels. Affected file is
2143 * Fixed some memory leaks around the server code.
2145 * Rewrote the silc_server_get_users_on_channel to support IPv6
2146 based Client ID's. Affected file silcd/server.c.
2148 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2149 specification. However, a separate document must be written
2150 to define the detailed signing procedure and the payload
2151 associated with the flag. Defined the flag to the
2152 lib/silccore/silcchannel.h as well.
2154 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Changed the dynamic tables to static size tables in the
2157 lib/silccrypt/silchmac.c.
2159 * Removed GCC dependencies from the code. A patch by cras.
2161 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Do not show the error "Error receiving packet bla bla"
2164 in server if it really was not an error (-2 means that reading
2165 is pending). Affected file silcd/server.c.
2167 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Fixed a possible crash in silc_server_remove_clients_by_server
2170 in silcd/server.c. Fixed there also some memory leaks.
2172 * Fixed the silc_idlist_replace_client_id. It could replace
2173 wrong key in the hash table. Affected file silcd/idlist.c.
2175 * Do not check whether there are global users on the channel
2176 if the channel->global_users is FALSE. Affected functions
2177 silc_server_remove_from_one_channel and
2178 silc_server_remove_from_channels in silcd/server.c. Also,
2179 do not check if the removed client is local as we can be
2180 sure that global client was not removed from the channel
2181 and checking for global users is not needed.
2183 * The silc_server_remove_clients_by_server now re-generates
2184 the channel keys correctly for those channels that had
2185 clients removed from them. Affected file silcd/server.c.
2187 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Found the reason of random crashes in the server. We weren't
2190 ignoring the SIGPIPE signal (which can be sent in write())
2191 and it crashed the server. Affected file silcd/silcd.c.
2193 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Assure that sock->user_data is not NULL in the function
2196 silc_server_packet_send in silcd/packet_send.c.
2198 * Disconnect the remote connection if it could not be added
2199 to any ID lists in the server. The affected file is
2202 * Check in silc_server_packet_send[_real/dest] that the
2203 socket is not disconnecting and ignore the data if it is.
2204 Affected file silcd/packet_send.c.
2206 * Define inline to __inline on native WIN32 compilation.
2207 Affected file includes/silcwin32.h.
2209 * Added some explicit type casts for inline code since MSVC
2210 require them. Affected files lib/silcutil/silcbuffer.h,
2211 lib/trq/silcdlist.h and lib/trq/silclist.h.
2213 * Print warning in log files from now on if the packet
2214 decryption fails. Affected file silcd/server.c.
2216 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Changed the `say' client operation's interface to accept
2219 new `type' argument to indicate the type of the message sent
2220 by the library. The application may filter the library's
2221 messages according the type. The affected file is the
2222 lib/silcclient/silcapi.h.
2224 * Added two new functions to lib/silcclient/silcapi.h:
2225 silc_client_del_client and silc_client_del_client_by_id.
2226 Affected file lib/silcclient/idlist.c.
2228 * Moved the clientincludes.h from includes/ to silc/ and
2229 serverincludes.h from includes/ to silcd/.
2231 * The modes for the CMODE and CUMODE are now passed as
2232 uint32 for application with COMMAND_REPLY. The affected
2233 file is lib/silcclient/command_reply.c.
2235 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * /WHOIS without arguments shows client's own information.
2238 Affected file lib/silcclient/command.c.
2240 * Changed PING to not accept any arguments. The specs
2241 says that client can ping only the connected server so
2242 requiring an argument is not needed. Affected file is
2243 lib/silcclient/command.c.
2245 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Fixed a fatal bug in private message sending and reception
2248 encryption and decryption when using private message keys.
2249 The implementation was incorrect and did not follow the
2250 specification. It causd that some of the message were
2251 lost since it did not use the sending and receiving keys
2252 as the protocol suggests. This has been fixed and will cause
2253 incompatibilities with older clients when sending private
2254 message encrypted with private message keys. Affected files
2255 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2256 and various other in Irssi SILC Client.
2258 Added `responder' boolean argument to the functions
2259 silc_client_add_private_message_key[_ske] to indicate when
2260 the key is added as responder or initiator of the key
2263 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Removed the silc_ske_check_version function and created
2266 a SilcSKECheckVersion callback. Added also a function
2267 silc_ske_set_callbacks that is now used to set all SKE
2268 callbacks. The callback functions are not given to
2269 the SKE functions anymore, but this function is used to
2272 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2274 * Added `silc_version' argument to the silc_client_alloc
2275 to define the version of the application for the library.
2276 The library will use the version string to compare it
2277 against the remote host's (usually a server) version
2278 string. Affected file lib/silcclient/silcapi.h
2280 * Added the KE protocol context to Key Agreement context
2281 in client library so that we can abort the SKE if it
2282 is in process when we get timeout. Affected file is
2283 lib/silcclient/client_keyagr.c.
2285 * Do not resolve the client ID forever if it returns in the
2286 first time that such client does not exist. This was done
2287 for example with private message. Affected file is
2288 lib/silcclient/client_prvmsg.c.
2290 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Do not add regex.h for WIN32. The affected file
2293 includes/silcincludes.h.
2295 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2296 not work yet 100%. It generates the DLL's automatically
2297 when compiling with --with-win32 under cygwin.
2299 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * lib/contrib/regex.c is not compiled on WIN32.
2303 * Added silc_net_get_socket_opt function to the
2304 lib/silcutil/silcnet.h.
2306 * Added includes/silcwin32.h for WIN32 specific includes
2309 * Do not use ptime structure or any of the posix process
2310 functions on WIN32 in lib/silccrypt/silrng.c.
2312 * Added silc_gettimeofday to provide generic function
2313 for struct timeval on all platforms. Added the function
2314 to lib/silcutil/silcutil.h.
2316 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2319 library as they clearly belong there. As a plus side we
2320 can make the actual socket connection routines platform
2323 Added also new generic function silc_socket_read and
2324 silc_socket_write (that used to be silc_packet_[read/write].
2325 The implementation of these are platform specific.
2327 * Added WIN32 specific routines of silc_socket_[read/write]
2328 to lib/silcutil/win32/silcwin32sockconn.c.
2330 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Added preliminary support for native WIN32 compilation under
2333 cygwin (using the -mno-cygwin option for GCC) to the
2334 ./configure.in.pre. The --with-win32 now prepares the
2335 compilation for native WIN32.
2337 * Rewrote the SILC Scheduler interface in the file
2338 lib/silcutil/silcschedule.h. The scheduler is now context
2339 based and does not have anymore any global static scheduler.
2340 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2341 and created lib/silcutil/win32 directory for WIN32 based
2344 * Added Unix specific network routines to the
2345 lib/silcutil/unix/silcunixnet.c and the old
2346 lib/silcutil/silcnet.c includes now only generic routines.
2348 Added WIN32 specific network routines to the
2349 lib/silcutil/win32/silcwin32net.c.
2351 * Added Unix specific utility functions from the
2352 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2354 * Added WIN32 SILC Scheduler to the file
2355 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2358 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Do not handle JOIN notify in the server if the target client
2361 is not registered (idata->registered == FALSE). The affected
2362 file is silcd/packet_receive.c.
2364 * Update the nickrec->founder in event_cumode in the Irssi SILC
2365 client. Affected file irssi/src/silc/core/silc-channels.c.
2367 * Fixed the CUMODE_CHANGE notify handling in the server when
2368 server and router are announcing their clients on channels.
2369 Now the mode changes are saved and notified correctly. The
2370 affected file is /silcd/packet_receive.c.
2372 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2373 They really did not replace the cache entry in the ID Cache.
2374 Now they do that. Affected file silcd/idlist.c.
2376 * Fixed the KICK notify handling in the Irssi SILC client to
2377 update the channel records so that the kicked client does not
2378 appear to be on the channel. The affected file is
2379 irssi/src/silc/core/silc-channels.c.
2381 * Always update the conn->current_channel when executing command
2382 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2384 * Fixed the KILL notify handling in Irssi SILC client to remove
2385 the killed client on all channels.
2387 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2389 * Fixed the silc_parse_command_line to remove extra spaces
2390 from the start and end of the arguments. Affected file is
2391 lib/silcutil/silcutil.c.
2393 * Cancel and free any active protocol in the function
2394 silc_server_close_connection. Affected file silcd/server.c.
2396 * Cancel and free any active protocol in the function
2397 silc_client_close_connction. Affected file is
2398 lib/silcclient/client.c.
2400 * Do not execute the KILL command for clients that are in
2401 history (ie. they are not in the network). Affected file is
2404 * Fixed KILL notify handling, client does not crash anymore.
2405 Affected file irssi/src/silc/core/silc-channels.c.
2407 * Reduced the default packet buffer size from 2048 to 1024 in
2408 lib/silccore/silcpacket.c.
2410 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2411 counter to the SKE context that is incresed when the SKE library
2412 performs async operation outside the library. If the outside
2413 process frees the SKE context and FREED status will be set
2414 and the library will detect after the sync operation that the
2415 libary is freed. The affected files are
2416 lib/silcske/silcske[_status].[ch].
2418 * Resolve the client entry information in the function
2419 silc_client_channel_message to assure that NULL pointer is not
2420 passed as client entry to the application. */
2422 * Fixed the task timeout calculation to assure that there is
2423 never negative timeouts. The affected file is
2424 lib/silcutil/silcschedule.c.
2426 * Fixed the channel user mode notification sending in server.
2427 It was sent point-to-point to the router (or to server by router)
2428 but it needs to be destined to a channel. The routines now
2429 supports sending the channel user mode notifys to the channels
2430 when announcing clients and channels. Affected files are
2431 silcd/server.c and silcd/packet_receive.c.
2433 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2434 It did not actually replace the old channel entry in the cache.
2435 Affected file lib/silcclient/client_notify.c.
2437 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Fixed a possible crash in silc_packet_send_prepare. It now
2440 assures always that there is enough space in the buffer and
2441 at the tail area of the buffer (for MAC).
2443 Fixed the inbound buffer reallocation in silc_packet_read.
2444 It was old code and did not handle the reallocation correctly.
2447 The affected file is lib/silccore/silcpacket.c.
2449 * Fixed buffer overflow in silc_parse_nickname in the file
2450 lib/silcutil/silcutil.c.
2452 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * make install generates new server keys only if there is not
2457 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2460 Added check that if the NOREPLY is set then we will not send
2461 the away message. This avoids infinite loop of away messages
2462 if both clients are away. The affected file is
2463 lib/silcclient/client_prvmsg.c.
2465 * Fixed client crash if /NICK was given without arguments.
2466 Affected file lib/silcclient/command.c.
2468 * Server does not send the invite list in INVITE command back
2469 to the client if the list was not altered. Added this notion
2470 to the protocol spec as well. Affected file silcd/command.c.
2472 Fixed possible crash in INVITE command by checking the
2473 value of silc_server_get_client_route command.
2475 * Fixed the INVITE notify type handling. The arguments are now
2476 taken in correct order and client does not crash. The affected
2477 file is irssi/src/silc/core/silc-channels.c.
2479 Removed the "Inviting xxx to channel" message from the
2480 client library away and let the application handle it.
2481 Affected file lib/silcclient/command.c. Added that message
2482 to Irssi SILC client's message formats.
2484 * Fixed CMODE command crash in client. It now checks the
2485 amount of arguments correctly and does not crash. The affected
2486 file is lib/silcclient/command.c.
2488 * Do not create new channel automatically in silc_channels_join
2489 but check whether the channel by that name already exists.
2490 Affected file irssi/silc/core/silc-channels.c.
2492 * Do not send the SERVER_SIGNOFF to router if the disconnected
2493 entity was the router. Affected file silcd/server.c.
2495 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2496 SILC client as it was missing from there.
2498 Added the handling of the KICK notify to the Irssi SILC client
2499 as it was missing. Added "you have been kicked" message to
2500 Irssi SILC client's message modules formats.
2502 Added the handing of the KILL notify to the Irssi SILC client
2503 as it was missing. Added the kill message module formats
2506 The affected file is irssi/src/silc/core/silc-channels.c.
2508 * The router did not save the channel mode the server announced.
2509 Affected file silcd/packet_receive.c.
2511 * Fixed a possible crash in INFO command in server. If the
2512 server did not provide the server info it crashed. Affected
2513 file silcd/command.c.
2515 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Fixed the GETKEY command in the server to check also the
2518 global list. Otherwise the GETKEY would not work correctly
2519 in normal SILC server. Affected file silcd/command.c.
2521 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2523 * Fixed GETKEY crash, it crashed if the command did not succseed.
2525 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2528 is now real and not just an macro interface to GMP.
2530 Removed the entire GMP from the source tree and imported new
2531 NSS MPI library instead. Reason for removing GMP is that it is
2532 extremely large and compiles extremely slow. The NSS MPI
2533 is only a few files and compiles in less than 10 seconds.
2534 The speed is also about the same as GMP. The MPI is imported
2535 to lib/silcmath/mpi.
2537 If the system has GMP installed we will still use the GMP.
2538 If it is not then the NSS MPI will be compiled.
2540 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * Merged a long nickname (127 characters long) crash bugfix from
2543 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2545 * Merged a freed memory reference bugfix from Irssi CVS tree.
2546 Affected file irssi/src/core/commands.c.
2548 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Added the server's public key sving and verification to the
2551 server when performing the SKE. This was missing and the
2552 remote server's (or router's) public key was accepted without
2553 checking whether we have it previously or trust it at all.
2554 Affected file silcd/protocol.c.
2556 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Check in the silc_server_timeout_remote if protocol is active
2559 and make sure that the protocol's final callback is called so
2560 that all memory if freed. Affected file silcd/server.c.
2562 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * silc_server_whois_send_reply crashed the server if the nickname
2565 was 127 characters long. Affected file silcd/command.c.
2567 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Added sanity check to the silc_server_new_client. If the hostname
2570 is provided inside username then check that the provided hostname
2571 really is the same as the resolved one. If the hostname was not
2572 resolved then check it from the public key. Affected file is
2573 silcd/packet_receive.c.
2575 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2576 if the server disconnected us and the connection is not valid
2577 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2579 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2580 the library to the lib/silcutil/silcutil.[ch].
2582 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Close log file after open. Affected file
2585 lib/silcutil/silclog.c.
2587 * Check whether sock == NULL in silc_client_send_packet and return
2588 if it is. Affected file lib/silcclient/silcclient.c.
2590 * Check rec->entry == NULL in the Irssi SILC Client before
2591 sending the channel message. Affecte file is
2592 irssi/src/silc/core/silc-servers.c.
2594 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Merged a splitted window bugfix from Irssi CVS tree. The
2597 affected file is irssi/src/fe-text/textbuffer-view.c.
2599 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2600 It did not print nickname.
2602 * Improved the distributions system a bit.
2604 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2607 irssi/src/fe-text/gui-window.c.
2609 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2610 to in-active server. The affected file is
2611 irssi/src/silc/core/client_ops.c.
2613 * Resolve the client in USERS command reply if the entry does
2614 not have username resolved. The affected file is
2615 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2616 command to WHOIS command to really resolve stuff. The USERS
2617 is not used any more in any critical section so WHOIS can
2618 be used even though it might be slower than IDENTIFY.
2620 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2623 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * Changed the protocol API a bit more consistent in the
2626 lib/silccore/silcprotocol.[ch].
2628 * Changed the following headers to ROBODoc format:
2630 lib/silccore/silcpayload.h
2631 lib/silccore/silcprotocol.h
2632 lib/silccore/silcsockconn.h
2634 All core library headers are now formatted.
2636 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Fixed a bug in Irssi SILC client; do not show that you are
2639 server/router operator if you really are not. Affected file is
2640 irssi/src/silc/core/client_ops.c.
2642 * Renamed silc_command_free_payload to silc_command_payload_free.
2643 Affected file lib/silccore/silccommand.h
2645 * Added silcmath.h to include the prototoypes of various routines
2646 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2649 * Changed the following headers to ROBODoc format:
2651 lib/silccore/silcchannel.h
2652 lib/silccore/silccommand.h
2653 lib/silccore/silcid.h
2654 lib/silccore/silcidcache.h
2655 lib/silccore/silcmode.h
2656 lib/silccore/silcnotify.h
2657 lib/silccore/silcpacket.h
2658 lib/silcmath/silcmath.h
2660 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2662 * Added checking to the server code not to start the server if
2663 ciphers and stuff are not configured properly. Affected files
2664 silcd/serverconfig.[h] and silcd/server.c.
2666 * Changed the layout of the header files of the public interfaces
2667 in the SILC libraries. The new layout supports ROBODoc
2668 documentation tool (and some others) so that it is easy to create
2669 a library reference manual. All the other headers and source
2670 code must still follow the CodingStyle document. Also source
2671 code must not include these ROBODoc stuffs, only the headers.
2672 Furthermore, all public interface headers must now be named
2673 by using `silc' prefix, example: silcapi.h, silccipher.h.
2674 Some files were renamed due to this. All the other headers
2675 must not be used as public interfaces. I will update the
2676 CodingStyle document later. Changed following headers, so far:
2678 lib/silcclient/silcapi.h
2679 lib/silccore/silcauth.h
2680 lib/silccore/silcprivate.h
2681 lib/silccrypt/silcdh.h
2683 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Removed silc_client_packet_send_flush from the client library
2688 as it is not needed. Affected file lib/silcclient/client.[ch].
2690 * Added printing of message of unresolved authentication method
2691 to the Irssi SILC client. Added it to the module formats.
2692 Removed the same message from the client library.
2694 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2696 * Added new distribution feature, DISTLABEL. Every distribution
2697 can define own preprocessor label that can be used in the
2698 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2699 file distributions, acconfig.h.pre and prepare.
2701 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Added Makefile.defines_int to include the actual definitions
2704 for Makefile.defines.in. Tested the new distribution system,
2705 created distributions and tested installation.
2707 * Added AWAY message printing to the Irssi SILC client. Added
2708 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2710 * Added SCONNECT command to call the SILC's CONNECT command.
2711 Cannot use CONNECT directly since Irssi uses that internally.
2712 Affected file irssi/src/silc/core/silc-servers.c.
2714 Added ACTION local command. It is same as ME command but takes
2715 the channel as mandatory argument.
2717 Rewrote some of the Irssi's help files to suite for SILC
2720 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Added Makefile.defines[.in] that should for now on be included
2723 in all Makefile.am file in the source tree. That file includes
2724 all common compilation definitions for SILC source tree.
2726 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Minor changes to the ./prepare script to change the package
2729 name according the distribution name to the configure.in.
2731 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Created new distribution system. Added file `distributions'
2734 that defines all the distributions that can be created out of
2735 the SILC source tree. The ./prepare script now reads that
2736 file to determine how to prepare the distributions. The
2737 first argument to the ./prepare is the name of the distribution
2738 and second is the version of the distribution. If given
2739 without arguments it creates the default (toolkit) distribution
2740 with the default version (defined in ./prepare).
2742 All Makefile.am files that are subject to the distributions
2743 are now named as Makefile.am.pre. These are ./Makefile.am
2744 and lib/Makefile.am. Others may be changed later.
2746 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2748 * Added invite list, ban list, some key management and connection
2749 error message printing to module formats in the Irssi SILC client.
2751 * Added new silc_client_set_away_message to set the away message
2752 that is back to the person who sent private message. The
2753 affected file lib/silcclient/silcapi.h and the
2754 lib/silcclient/client_prvmsg.c.
2756 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Fixed the private message sending in the Irssi SILC client,
2759 added local command KEY to the Irssi SILC client.
2761 Added key management and key agreement message formats to the
2762 irssi/src/fe-common/silc/module-formats.[ch].
2764 Added USERS (alias WHO) printing, server/router operator
2765 indication and LIST command printing to the module formats.
2767 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Fixed channel joining notify handling, cumode notify handling
2770 from Irssi SILC client.
2772 * Added SILC specific module-formats to the Irssi SILC client so
2773 that SILC specific message hilighting, colors etc is possible.
2774 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2776 Added channel mode, channel user mode, actions, notices,
2777 whois and whowas printing to the the module-formats.c.
2779 * Fixed a bug in channel deletion in the server. The channel
2780 is not left to the cache even if the channel founder auth mode
2781 is set when there are no users anymore on the channel. Affected
2782 file silcd/server.c.
2784 * The silc_net_localhost now resolves the entire hostname including
2785 the domain name. Affected file lib/silcutil/silcnet.c.
2787 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Changed the ask_passphrase client operation to be ascynchronous.
2790 It has now a completion callback and a context that the
2791 application must call after it has got the passphrase from
2792 the user. Affected files lib/silcclient/silcapi.h,
2793 lib/silcclient/protocol.c, lib/silcclient/command.c and
2796 Added SilcAskPassphrase callback that the application calls
2797 to deliver the passphrase to the library.
2799 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2800 The public key verification and especially a certificate
2801 verification is asynchronous procedure.
2803 Added new SILC_SKE_STATUS_PENDING status to indicate the
2804 request is pending and a callback will be called to finalize
2807 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2808 indicate that remote end did not send its public key (or
2809 certificate), even though we require it. Added check for this
2810 condition in the SKE. This was a security bug, now fixed.
2812 Defined new SilcSKEVerifyCbCompletion callback that is called
2813 when the verification process is completed.
2815 The affected files lib/silcske/silcske_status.h and
2816 lib/silcske/silcske.[ch].
2818 * Changed the verify_public_key client operation to be async
2819 as well. Defined SilcVerifyPublicKey callback that is used to
2820 indicate the success of the public key verification process.
2822 Changed the server and client to use the new async client
2825 * Changed the Irssi SILC client's internal scheduler to be called
2826 twice as many times as it used to be. As a result the client
2827 should be a bit faster now. Affected file is
2828 irssi/src/silc/core/silc-core.c.
2830 * Added support to Irssi SILC client of asynchronous public key
2831 verification and passphrase inquiry. Affected file is
2832 irssi/src/silc/core/silc-core.c.
2834 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Do not say "You have left channel %s" in client library.
2837 Moved it to the application. Affected files are
2838 lib/silcclient/command.c and silc/client_ops.c.
2840 * Fixed silc_client_get_clients. Command context was not
2841 duplicated and was freed memory in the callback. Affected
2842 file lib/silcclient/idlist.c.
2844 * Do not say "you are now talking..." on JOIN command in the
2845 client library. The appliation must handle it.
2847 * Do not say ".. changed topic to" in command reply in the
2848 client libary. The application must handle it.
2850 * Fixed TOPIC command sending in the client library.
2852 * Fixed a memory leak in silc_client_command_free in the file
2853 lib/silcclient/command.c.
2855 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Imported a modified version of Irssi client to the source tree.
2858 The Irssi will be used to create a new client called
2859 Irssi SILC. Imported to irssi/.
2861 Added silc_core_init_finish function to the Irssi. Affected
2862 file irssi/configure.in.
2864 A lot changes in the Makefile.ams around the irssi tree.
2866 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Do not rehash if the new size is same as the old size of the
2869 hash table, in the silc_hash_table_rehash*. The affected file
2870 lib/silcutil/silchashtable.c.
2872 * Replaced hash_table_del_by_context calls from the server
2873 (when channel->user_list and client->channels) to the
2874 hash_table_del as it is sufficient and faster.
2876 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2878 * Added silc_hash_table_list, silc_hash_table_get and the
2879 SilcHashTableList structure to provide an alternative way to
2880 traverse the hash table. The affected files are
2881 lib/silcutil/silchashtable.[ch].
2883 * Changed the server's idlist routines to use the hash table
2884 routines to optimize the code.
2886 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2888 * Replaced the client entry's `channel' list and channel entry's
2889 `user_list' list to hash tables for optimized lookup. Changed
2890 the code to use the hash table interface around the code.
2891 Affected file lib/silcd/idlist.[ch].
2893 * Added `auto_rehash' boolean argument to the function
2894 silc_hash_table_alloc to indicate whether the hash table should
2895 auto-rehash when it thinks is appropriate time. It will
2896 increase the hash table size if the there is twice as much
2897 entries in the table than the size of the table, and will
2898 decrease the size if there are twice as less entries than
2899 the size of the table.
2901 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2905 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * silc_idcache_purge_by_context deletes the entry now by context
2908 as it is supposed to do. Affected file lib/silccore/idcache.c.
2910 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2911 client is not anymore valid (WHOWAS givens the info) and not
2912 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2914 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Removed the `data' and `data_len' arguments from the ID Cache
2917 interfaces and added `name' argument. ID Cache does not handle
2918 anymore the binary data only a names associated with given ID.
2920 * When hashing a Client ID with silc_hash_id the entire ID is
2921 not hashed anymore, instead only the hash of the Client ID is
2922 hashed. This way we can access the Client ID from the cache
2923 with Client ID but with the hash of the ID (which is a hash of
2924 the nickname) as well without any difference in performance.
2926 Added also silc_idcache_find_by_id_one_ext to do one on one
2927 searching when we have the actual ID. Added also function
2928 silc_hash_client_id_compare. The affected files are
2929 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2931 * When hashing the name associated with a ID it is always done
2932 in lowercase. This way we can access the cache without worrying
2933 about case-sensitivity, even though, for example nicknames are
2936 * Fixed a bug in server with channel message sending. It put
2937 wrong ID type as destination ID. The affected file
2938 silcd/packet_send.c.
2940 * silc_idcache_del_by_context now deletes from all hash tables
2941 by context. Affected file lib/silccore/idcache.c.
2943 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Changed the client library to use the new ID Cache interface.
2946 Changes around the source tree.
2948 * Added silc_hash_table_rehash_ext to rehash with specific
2949 hash function. Affected file lib/silcutil/silchashtable.[ch].
2951 * Added silc_hash_string_compare to compare two strings in the
2952 hash table. Affected file lib/silcutil/silcutil.[ch].
2954 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Added new function silc_idcache_del_by_context into the
2957 lib/silccore/idcache.[ch].
2959 * Changed the server's ID list routines to use the new ID Cache
2960 interface. Changes around the source tree.
2962 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Added silc_hash_table_del[_by_context]_ext functions in to the
2965 lib/silcutil/silchashtable.[ch].
2967 Removed silc_hash_table_find_all* routines and added new
2968 silc_hash_table_find_foreach to replace them.
2970 Added silc_hash_table_replace_ext function as extended
2971 replacing function. Separated the simple hash table interface
2972 from the extended hash table interface in the file
2973 lib/silcutil/silchashtable.h.
2975 * Fixed minor bugs and changed it to use some of the new
2976 hash table functions in lib/silccore/idcache.c
2978 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Added new function silc_hash_table_find_all to return all keys
2981 in the hash table by the specified key. As the hash table is
2982 collision resistant it also makes it possible to have several
2983 duplicate keys in the hash table. This function may be used to
2984 find all of the keys from the hash.
2986 Added user_context arguments to the SilcHashFunction,
2987 SilcHashCompare and SilcHashDestructor to deliver user specified
2990 Added new fuctions silc_hash_table_find[_all]_ext to do
2991 extended lookup with specified hash and compare functions and
2992 specified user contexts.
2994 Added new function silc_hash_table_add_ext to add the key
2995 with specified hash function and user context.
2997 Added new function silc_hash_table_foreach to traverse all
2998 entrys in the hash table. Added SilcHashForeach callback
3001 Added new function silc_hash_table_del_by_context to delete
3002 the entry only if the context associated with the key matches.
3004 Affected files are lib/silcutil/silchashtable.[ch].
3006 * Removed silc_hash_[server/client/channel]_id and added just
3007 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3008 silc_hash_id_compare to compare two ID's using as the hash table
3009 comparison function. Added also silc_hash_data to hash
3010 binary data and silc_hash_data_compare to compare it.
3012 * Removed silc_idlist_find_client_by_hash as it is not needed
3013 anymore. Affected file silcd/idlist.[ch].
3015 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3016 to use internally the SilcHashTable. The new ID Cache is a lot
3017 faster than the old one. Some of the ID Cache interface was also
3018 rewritten and obsolete and stupid functions were removed.
3020 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Added entry_count field to the SilcHashTable to keep the number
3023 of the entries in the table. Implemented the function
3024 silc_hash_table_rehash. Added new function
3025 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3027 Fixed a minor bug in silc_hash_table_free.
3029 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3030 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3031 into the lib/silcutil/silcutil.[ch].
3033 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Implemented a collision resistant hash table into the
3036 lib/silcutil/silchashtable[ch]. See the header and the source
3037 for the SilcHashTable API.
3039 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Merged dotconf version 1.0.2 into lib/dotconf.
3043 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Do not compile anything in lib/silcsim/* if the SIM support
3046 is not enabled. The tree should now compile without problems
3049 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Compiled the SILC under cygwin. Compiled and tested briefly
3052 without problems. More tests needed. The SIMs didn't compile
3055 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3057 * Fixed possible crash in silc_get_username in the
3058 lib/silcutil/silcutil.c.
3060 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Fixed a va_arg in silc/client_ops.c.
3064 * Oops, RC5 routines were named AES and caused some problems
3065 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3067 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Added new SilcIDIP structure into the lib/silccore/id.h and
3070 replaced the old `ip' fields from all SILC ID's to that type.
3071 This is a step towards IPv6 support.
3073 The silc_id_get_len takes now the ID as an extra argument.
3074 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3075 both IPv4 and IPv6 based ID's.
3077 The affected files are lib/silccore/id.[ch] and other files
3078 around the tree using these routines.
3080 * Removed the ID length arguments in server from various
3081 silc_server_send_notify_* routines -> they are not needed
3084 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Fixed memory leak in silc_encode_pem_file in the file
3087 lib/silcutil/silcutil.c.
3089 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Check minor version as well in the SKE. Affected files are
3092 silcd/protocol.c and lib/silcclient/protocol.c.
3094 * Added --identifier option to the server so that an identifier
3095 can be when creating the public key for the server. Affected
3096 file is silcd/silcd.c.
3098 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3099 lib/silccrypt/silcpkcs.c.
3101 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Register default ciphers and stuff when using -C option with
3104 the server. Affected file sildc/silcd.c.
3106 * Put back the servers public key filename format, it is better
3107 than the new one. For now, the client keys are saved with the
3108 new filename format. The affected file silc/client_ops.c.
3110 * Implemented the Cipher API for the rest of the ciphers that
3111 did not implement it or implemented it the wrong way.
3113 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Register default ciphers and stuff when using the -S option
3116 in the client. Affected file silc/silc.c. Same also when
3117 creating new key pair with -C option.
3119 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Fixed the silc_verify_public_key client operation function to
3122 save the public keys differently. The fingerprint is now
3123 used as filename and not the hostname. This way also the
3124 client keys are saved uniquely and not with hostnames. The
3125 affected file is silc/client_ops.c.
3127 * Trimmed the silc_hash_fingerprint function to remove extra
3128 whitespaces from the end of the fingerprint. The affected
3129 file is lib/silccrypt/silchash.c.
3133 * Added silc_cipher_register_default function to register all
3134 default ciphers. It can be used when configuration files
3135 does not exist and the application does not want any specific
3136 ciphers in any specific order.
3138 The SilcDList is now used as silc_cipher_list dynamically
3139 allocated cipher list. Removed the static list all together
3140 and now all ciphers must be allocated to the dynamic list.
3141 The silc_cipher_alloc routine was changed to check only the
3144 All silc_cipher_* routines that used to return int returns
3147 The affected files lib/silccrypt/silccrypt.[ch].
3149 * The same thing was done to silc_hash_* as for silc_cipher_*
3150 routines. Affected files lib/silccrypt/silchash.[ch].
3152 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3153 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3154 Added also silc_pkcs_[un]register[_default] functions.
3155 Removed the data_context from the PKCS API.
3157 * Added silc_hmac_register_default function to register default
3158 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3159 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3160 to unregister all hmacs at once.
3162 * Register the default ciphers, hash functions, PKCSs and HMACs
3163 if client's configuration file does not exist. The affected
3166 * The client did not load the hash functions from the SIM
3167 modules at all. Added support for this. Affected file is
3168 silc/clientconfig.c.
3170 * When decoding public key with silc_pkcs_public_key_decode, check
3171 the supported algorithm only if PKCS are registered. Affected
3172 file lib/silccrypt/silcpkcs.c. The same was done with the
3173 silc_pkcs_private_key_decode.
3175 * Fixed the SILC List routines to keep the list always in order.
3176 It used to change the list's order when traversing the list but
3177 not it preserves the order. Affected file lib/trq/silclist.h.
3179 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Added the client library to use the SilcSocketConnection's
3182 reference counter (by silc_socket_dup) to prevent the bug that
3183 the socket object may be freed underneath async operation.
3185 * The name resolv library checking fixes in the configure.in.pre.
3188 * Created new version of the protocol drafts for future
3189 development. The -03 drafts are the ones that will be changed
3190 in the trunk now and the -02 will remain as they are.
3192 * Send list of CUMODE notifys to the router when announcing
3193 the channel users to the router. Affected file silcd/server.c.
3194 If the router receiving channel founder CUMODE for a channel
3195 that already has channel founder it will send CUMODE notify
3196 to the sender to remove the channel founder rights from the
3197 announced client. Affected file silcd/packet_receive.c.
3199 * The CUMODE notify may now use Server ID as well as the entity
3200 who changes the mode. Updated protocool specs.
3202 * Updated INSTALL and README files.
3204 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * New web pages in the http://silc.pspt.fi. The pages was
3211 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Implemented the [DenyConnectin] config section in the server.
3214 Added silc_server_config_denied_conn to check whether incoming
3215 connection is denied. Affected file silcd/serverconfig.[ch].
3217 * Do not check the ports when checking the incoming configuration
3218 data if the port is 0, meaning any. Affected file is
3219 silcd/serverconfig.c.
3221 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Fixed buffer overflow in silc_string_compare in the file
3224 lib/silcutil/silcutil.c.
3226 * Fixed double free in silc_server_command_leave in the file
3229 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Fixed the version checking in the server. Affected file is
3234 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Fixed the configuration data fetching when accepting new
3237 connections in the server. Affected file silcd/server.c.
3239 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Added `sender_entry' argument to the function
3242 silc_server_packet_relay_to_channel so that we can check
3243 whether some destination actually belongs to the same route
3244 the sender belongs (ie, we must not resend the packet to the
3245 sender). Affected file silcd/packet_send.[ch].
3247 * Added `servername' field to the SilcClientEntry in the server
3248 to hold the name of the server where client is from. Affected
3249 file is silcd/idlist.h.
3251 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Moved the channel message encrypting in the router betwen
3254 router connections from silc_server_channel_message to the
3255 silc_server_packet_relay_to_channel since we want to check
3256 whether we have anybody channel before encrypting anything.
3257 Affected files silcd/packet_[receive/send].c.
3259 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Fixed the [AdminConnection] server config section to support
3262 multiple entries. Affected file silcd/serverconfig.c.
3264 * Added support into the server to check the validity of the
3265 incoming connection before executing any KE or authentication
3268 * The connection configuration is now saved to the KE and
3269 connection auth protocol contexts and not fetched anymore in
3270 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3272 * The local hosts listenning address and port is also resolved
3273 now when starting the server. We want to have the socket object
3274 to include the real address and port for the listener. Added
3275 new function silc_net_check_local_by_sock into the files
3276 lib/silcutil/silcnet.[ch].
3278 * Fixed a broadcast bug in server -> do not broadcast if we
3281 * Fixed a routing bug. Do not route broadcast packets ever.
3282 Broadcast packets must be processed always and not routed since
3283 they may be destined to some other host than yourself and thus
3284 would get routed without no good reason. Affected file is
3287 * Added function silc_server_config_is_primary_route to check
3288 whether primary router connection has been configured (a router
3289 configuration that we are initiating). If there is not, we
3290 will assume that there is only two routers in the SILC network
3291 and we will use the incoming router connection as our primary
3292 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3294 * Changed the order of the broadcasting. Broadcast _after_ the
3295 packet has been processed not before. Affected file is
3298 * Fixed a [ClientConnection] parsing bug. The port was never
3299 parsed correctly thus resulting to port 0. Affected file
3300 silcd/serverconfig.c.
3302 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3303 argument and did not set the broadcast packet flag. Affected
3304 file silcd/packet_send.c. Fixed same bug in the function
3305 silc_server_send_notify as well.
3307 * If we receive NEW_ID packet for our own ID in the server, ignore
3310 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Removed the nickname from the Private Message Payload.
3315 Updated the code and the protocol specs.
3317 * Updated protocol specs for submitting to the IETF.
3319 * Tweaked the Random Number Generator a bit. Affected file
3320 lib/silccrypt/silcrng.c. Exported a new function
3321 silc_rng_[global]_add_noise which can be used to add more
3324 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Do not parse packets with different timeout when protocol
3327 is active -> may cause problem with rekey. Affected file
3330 * When server receives signoff notify it must not create
3331 new channel key if the client is on any channels since the
3332 sender of the signoff notify will create it.
3334 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Added printing of error messages during SKE protocol from the
3337 failure packet sent by server during SKE. Affected file
3340 * Removed the client's failure_callback handling with timeout
3341 and handle it immediately when received.
3343 * The SKE library returned wrong type in SUCCESS and FAILURE
3344 packets. They must be 32 bit MSB not 16 bit MSB.
3346 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Ok, rewrote the logic of the re-key and now it seems to work.
3349 I tested it on high traffic with frequent re-keys without
3350 problems. Added hmac_receive (and renamed hmac to hmac_send)
3351 in SilcClientConnection in lib/silcclient/client.h and
3352 in SilcIDListData in silcd/idlist.h. Also, removed the
3353 SilcPacketParserContext's cipher and hmac fields as they are
3354 not needed anymore and actually caused some problems when
3355 the ciphers and hmac's changed underneath the packet parser.
3357 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * If re-key protocol is active then process the incoming packets
3360 synchronously since we must assure that icoming packets encrypted
3361 with the old key is processed before the new keys is set to
3362 use. This is true other packets than for REKEY packets.
3363 Affected file silcd/server.c. The same was done to client library
3364 as well, affected file lib/silcclient/client.c.
3366 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Fixed bug in client and server to accept the force send if
3369 the packet is send from silc_[server/client]_packet_process
3370 function. Otherwise the packets are never delivered, oops.
3372 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Disable force sending of packets when REKEY protocol is active.
3375 We must assure that no packet is sent directly when rekey is
3376 performed. All packets must be sent through packet queue.
3377 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3378 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3379 function is silc_[server/client]_packet_send_real to check
3382 * Replaced the SIM paths from example config files to
3383 /usr/local/modules. Also, make install creates now
3384 /usr/local/silc/logs directory to hold all the SILC server
3387 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Made the configure.in.pre work on Solaris. Patch by salo.
3391 * Made all ciphers compatible with non-x86 machines. Defined
3392 CBC mode macros into lib/silccrypt/ciphers_def.h.
3394 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Fixed the make install.
3398 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * When MAC computation fails the silc_packet_decrypt returned 0
3401 even though it was supposed to return -1. Fixed this. The
3402 affected file is lib/silccore/silcpacket.c.
3404 * Do not replace the config files in /etc/silc (in make install)
3405 if they already exist. Affected file ./Makefile.am.
3407 * Do not send re-key packets immediately but through packet queue.
3408 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3410 * Changed silc_net_check_host_by_sock to return FALSE if the
3411 IP/DNS could not be resolved. Though, it returns the IP address
3412 now even if it could not resolve it (but returns also FALSE).
3413 Affected file lib/silcutil/silcnet.[ch].
3415 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Added silc_pkcs_decode_identifier to decode the public key's
3418 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3419 Added also silc_pkcs_free_identifier. Added also new context
3420 SilcPublicKeyIdentifier.
3422 * Added -S option to the silc client. It is used to dump the
3423 contents of the specified public key file.
3425 * Changed the PKCS api to return the public key length when
3426 setting the public key.
3428 * Fixed a fatal bug in the public and private key file loading.
3429 Affected file lib/silccrypt/silcpkcs.c.
3431 * Execute the packet parsing for client with zero (0) timeout
3432 if the protocol is active. Affected file silcd/server.c.
3434 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Made the key generation options to the silcd program. Added
3437 -C option, equivalent to client's option.
3439 * Added new [ServerKeys] config section to the server. It
3440 configures the server's public and private key.
3442 * Defined generic Public Key Payload into the protocol
3443 specification to send specific type of public keys and
3446 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3447 public key or certificate.
3449 * Implemented the GETKEY command to the server and to the
3450 client library and on user interface.
3452 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Made preliminary `make install' work.
3456 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added SilcServerRekey context into silcd/idlist.h.
3460 * Added the PFS support as defined in the specification to the
3461 SKE protocol. Affected files lib/silcske/*.c.
3463 * Added `ske_group' field to the SilcServerRekey context to hold
3464 the number of the SKE group that is used with PFS in re-key.
3465 Affected file silcd/idlist.h.
3467 * Added PFS re-key support to the server. Affected file is
3470 * Added silc_protocol_cancel to cancel execution of the next
3471 state of the protocol. Affected file is
3472 lib/silccore/silcprotocol.[ch].
3474 * Added the re-key support with and without PFS to the client
3475 library. Re-key is performed once in an hour, by default.
3477 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3478 Added silc_client_rekey_callback and silc_client_rekey_final.
3479 Affected files are lib/silcclient/protocol.[ch] and
3480 lib/silcclient/client.[ch].
3482 * Removed the `hmac_key' and `hmac_key_len' fields from the
3483 SilcClientConnection structure; not needed. Affected file is
3484 lib/silcclient/client.h.
3488 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3490 * Do not ask whether user wants to use the negotiated private key
3491 for private messages, just use it. Affected file is
3492 silc/local_command.c.
3494 * Added `send_enc_key' and `enc_key_len' fields to the
3495 SilcIDListData structure since they are needed in the re-key
3496 phase. Affected file is silcd/idlist.[ch].
3498 * Implemented the simple re-key protocol into the server.
3499 Affected files silcd/server.c and silcd/protocol.[ch]. The
3500 re-key will be performed once in an hour, by default.
3502 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3503 Added silc_server_rekey, silc_server_rekey_callback and
3504 silc_server_rekey_final.
3506 * Removed Tunneled flag from the protocol. Updated the code
3507 and the specifications.
3509 * Adde `pfs' field to the SilcIDListData to indicate whether
3510 the PFS is to be performed in the re-key. Affected file is
3513 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3516 int64 of at least the xintXX size. If void * is less that 4
3517 bytes uint32 * will be used. Defined bool as boolean.
3519 * Changed _ALL_ unsigned long and unsigned int to uint32,
3520 unsgined short to uint16 in the source tree.
3522 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3523 not handle clients that has entry->data.registered == FALSE.
3524 They are not in the network anymore. Affected file is
3527 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3529 * Implemented the sending of the SERVER_SIGNOFF notify in the
3530 server. Affected file is silcd/server.c.
3532 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3533 Added also silc_notify_payload_encode_args into the
3534 lib/silccore/silcnotify.[ch].
3536 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3537 Affected file silcd/packet_receive.c.
3539 * Implemented the SERVER_SIGNOFF notify handling in the client
3540 library. Affected file lib/silcclient/client_notify.c. Also,
3541 implemnted the printing of the SERVER_SIGNOFF info to the
3542 application. Affected file silc/client_ops.c.
3544 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3545 if the deleting was successful. Affected file silcd/idlist.[ch].
3547 * Added support for public key authentication in the connection
3548 authentication protocol in the client library. Affected file
3549 lib/silcclient/protocol.c.
3551 * Changed the server's silc_idlist_get_clients_by_* interface
3552 to support already allocated array so that new entries may be
3553 added to pre-allocated array. Affected file silcd/idlist.[ch].
3554 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3555 and command replies.
3557 * All command reply functions in the server now calls the
3558 pending command callback even if error occured. This way the
3559 error will be delivered to the client as well. Affected files
3560 silcd/command.c and silcd/command_reply.c.
3562 * Fixed INFO command to return local server's info if no server
3563 was provided. Affected file lib/silcclient/command.c.
3565 * Removed RESTART command for good. Updated the code and the
3568 * Rewrote parts of the task system. It is a bit simpler now.
3569 Removed unsued task priorities. The affected files are
3570 lib/silcutil/silctask.[ch].
3572 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Moved the USERS printing from the library to the application.
3575 Affected files lib/silcclient/command.c and silc/client_ops.c.
3577 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Added channel key re-key support. The re-key is perfomed
3582 only by the router and is done once in an hour. Added `rekey'
3583 field to the SilcChannelEntry in the server. Affected files
3584 silcd/server.c and silcd/idlist.h.
3586 * Added silc_task_unregister_by_context into the file
3587 lib/silcutil/silctask.[ch].
3589 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Added SILC_UMODE_GONE mode to indicate when the client is not
3592 present in the SILC network. Added also support to the local
3593 command AWAY that will set this mode. Added support of showing
3594 "xxx is gone" in WHOIS command. The USERS command shows the
3595 gone status as well.
3597 * Fixed setting server and router operator privileges in the
3598 server's UMODE command. Affected file silcd/command.c.
3600 * Merged the SKE KE1 and KE2 payloads into one payload. The
3601 new KE payload is equivalent to the old KE2 payload.
3603 Cleaned up the SKE Start Payload parsing. It now uses the
3604 simple buffer unformatting to do the parsing. A lot faster
3607 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3608 to the SKE that is used to indicate whether both of the SKE
3609 parties should perform authentication. By default only the
3610 responder performs authentication. By setting this flag also
3611 the initiator must do authentication. By default it is unset
3612 since in normal SKE case, client to server connection, only
3613 the responder should do authentication. When doing SKE between
3614 two clients both should perform authentication. Updated the
3615 code and the protocol specs.
3617 * A little fix to IDENTIFY command in the server. Search the
3618 client first by hash not nickname. Affected file is
3621 * Fixed the silc_client_close_connection to support closing
3622 the client to client connections wihtout deleting too much
3623 data. Affected file lib/silcclient/client.c.
3625 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3626 are received if protocol used to be active but is not anymore
3627 the application would crash due to NULL pointer dereference.
3628 Affected files silcd/server.c and lib/silcclient/client.c.
3630 * Added `hash' field to the SilcClientConnection to include
3631 the hash function negotiated in the SKE protocol.
3633 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3634 to set the channel founder authentication data. A client can
3635 claim the founder rights later by providing the authentication
3636 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3637 This way the channel founder can regain the channel founder
3638 privileges even it is left the channel. This works only on
3639 local server and the client must be connected to the same
3640 server to be able to regain the founder rights. Updated the
3641 protocol specs accordingly.
3643 Added support to the CMODE command in the client to set the
3644 founder auth data. Read the README to see how to set it.
3646 Added support to the CUMODE command to claim the founder
3647 rights. Read the README to see how to do it.
3649 Added support for the founder authentication to the Channel
3650 Entry in the server. Affected file silcd/idlist.h.
3652 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3653 server's CMODE command. Affected file silcd/command.c.
3655 * Added the following new functions into lib/silccore/silcauth.[ch]:
3656 silc_auth_get_method and silc_auth_get_data.
3658 * The server now saves the remote hosts public key to the
3659 SilcIDListData pointer. Affected file silcd/protocol.c.
3661 * The normal server now does not remove the channel entry from
3662 the cache if the founder authentication data is set. It used
3663 to remove it if the founder was the last one on the channel on
3664 the server and left the channel. The auth data is saved and
3665 if the channel is re-joined later the old entry is used with
3666 the old auth data. Affected files silcd/command_reply.c and
3669 * Removed the `pkcs' field from the SilcIDListData structure
3670 in the server; it is not used. Affected file silcd/idlist.h.
3672 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Fixed packet processing on slow links. Partial packets were
3675 never re-processed because the incoming data buffer was cleared
3676 by the application. Application must not directly clear the
3677 sock->inbuf, the packet processing routines handle it. Fixed
3678 this in client library and in server.
3680 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Fixed the WHOIS and IDENTIFY send reply function to really
3683 check whether to send list or just one entry. Affected file
3686 * Cleaned up the LEAVE command's channel key distribution. The
3687 affected file silcd/command.c.
3689 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3690 can enforce the channel mode as well. In that case the ID
3691 includes the ID of the server. The code now enforces the
3692 mode change if the router have different mode than the server.
3694 * The notify client operation with CMODE_CHANGE notify can now
3695 return NULL client_entry pointer if the CMODE was not changed
3696 by client. Application must check for this.
3698 * Added <Server ID> argument to INFO command to support server
3699 info fetching by Server ID.
3701 * Added silc_server_announce_get_channel_users to get assembled
3702 packets of channel users of the specified channel. Affected
3703 file silcd/server.[ch].
3705 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3706 was freed underneath the ID Cache.
3708 * Re-announce clients when the server received CHANNEL_CHANGE
3709 notify from the router. Affected file silcd/packet_send.c.
3711 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3714 crashed since it did not handle the fact that there is no cipher
3715 called "3" and didn't check the error condition. Now fixed.
3717 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3718 flag. It can be used to send message requests.
3720 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Implemented the RESTART command in the client.
3724 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3725 notice type messages. Added notice printing to the user
3728 * The channel keys are not re-generated if the channel's mode
3729 is PRIVKEY, ie private key on the channel exists. Affected
3730 files silcd/server.c and silcd/command.c.
3732 * Fixed a little bug in channel message delivery when channel
3733 private keys are set in the server. Affected file is
3734 silcd/packet_send.c.
3736 * Changed the setting on channel->on_channel = TRUE from the
3737 silc_client_save_channel_key to the JOIN command reply. The
3738 key payload is not received if the private channel key is set.
3739 Affected file lib/silcclient/command_reply.c and the
3740 lib/silcclient/client_channel.c.
3742 * When the CMODE_CHANGE notify is sent and the channel private
3743 key mode is removed the channel key must be re-generated in
3744 other cells as well. Added this support for the router in the
3745 silcd/packet_receive.c.
3747 * Added new local command NOTICE to send notice message on
3748 channel. Affected file silc/local_command.[ch].
3750 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Added new local command ME to the client. It is used to send
3753 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3754 some action. Affected file silc/local_command.[ch].
3756 * Changed channel_message and private_message client operations
3757 to deliver the message flags to the application. Added also
3758 the `flags' arguments to the silc_client_send_channel_message
3759 and silc_client_send_private_message functions. Affected file
3762 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Redefined the Private Message Payload to support private message
3765 keys and to support the new private message flags. Updated
3766 the protocol specs. Flags makes it possible to have for example
3767 CTCP style messages.
3769 * Added new type SilcPrivateMessagePayload and defined an API
3770 for it in the lib/silcclient/silcprivate.[ch].
3772 * Tested private message private keys successfully. Tested the
3773 private message key set, unset and list commands with the new
3776 * Redefined the Channel Message Payload to include the channel
3777 message flags (equal with private message flags) to support
3778 for example CTCP style messages.
3780 * Defined some of the message (for channel and private message)
3781 flags. Updated the protocol specs and added the flags to the
3782 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3784 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * Added SilcKeyAgreementStatus type to the key agreement routines
3787 to indicate the current status and error if one occured.
3788 The status types are defined in the lib/silcclient/silcapi.h.
3790 * Added new local command KEY that is used to set and unset private
3791 keys for channels, set and unset private keys for private messages
3792 with remote clients and to send key agreement requests and
3793 negotiate the key agreement protocol with remote client. The
3794 key agreement is supported only to negotiate private message keys,
3795 it currently cannot be used to negotiate private keys for channels,
3796 as it is not convenient for that purpose.
3798 * Fixed a minor pending callback setting bug in the function
3799 silc_client_get_client_by_id_resolve, now the function works.
3800 Affected file lib/silcclient/idlist.c.
3802 * Added function silc_net_get_local_port to get local bound
3803 port by socket. Added to lib/silcutil/silcnet.[ch].
3805 * Added `sockets' and `sockets_count' fields to the SilcClient
3806 object. They hold the sockets of the listenning sockets in
3807 the client. Listenning sockets may be for example the key
3808 agreement server. Affected file lib/silcclient/client.[ch].
3809 Added functions the silc_client_add_socket and the
3810 silc_client_del_socket. They are exported to the application
3813 * Added ~./silc/clientkeys to support other client's public keys.
3815 * Renamed verify_server_key client operation to verify_public_key
3816 and added one argument to indicate the type of the connection
3817 (server, client etc.).
3819 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Added silc_server_connection_auth_request to handle the
3822 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3823 silcd/packet_receive.[ch].
3825 * Added silc_server_send_connection_auth_request into the
3826 silcd/packet_send.c to send the connection auth request packet.
3828 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3831 * Fixed the public key authentication in responder side in the
3832 server. The `auth_data' pointer includes the SilcPublicKey
3833 not the path to the public key. Affected file silcd/protocol.c.
3835 * Implemented the public key authentication in the initiator side
3836 in the server. Affected file silcd/protocol.c.
3838 * Removed the [RedirectClient] config section from the server
3839 configuration. Is not needed and I don't want to implement it.
3841 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Cleaned up the CMODE command in the server. It now works
3844 correctly and supports all the modes defined in the protocol.
3845 Affected file is silcd/command.c.
3847 * Added `hmac_name' field to the SilcChannelEntry in the server
3848 to hold the default HMAC of the channel. It can be set when
3849 creating the channel (with JOIN command). Affected files
3852 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3853 type to indicate the change of the current cipher and hmac
3854 on the channel. Client can safely ignore the <cipher> argument
3855 (if it chooses to do so) since the CHANNEL_KEY packet will
3856 force the channel key change anyway. The <hmac> argument is
3857 important since the client is responsible of setting the new
3858 HMAC and the hmac key into use.
3860 * Fixed the CMODE command in the client library as well.
3862 * Tested CMODE command in router environment successfully.
3864 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3866 * Show the version of the remote client (or server) when connecting
3867 to the server. It is logged to the log file. Affected file
3868 is silcd/protocol.c.
3870 * Fixed the KILLED notify handling in the client library. The
3871 client must be removed from all channels when receiving the
3874 Also, do not remove the client entry when giving the KILL
3875 command but when the KILLED notify is received.
3877 * Removed silc_idlist_find_client_by_nickname from the server.
3878 Not needed anymore. Affected files silcd/idlist.[ch].
3880 * Implemented the CHANNEL_CHANGE notify type handling to the
3881 server. Affected file silcd/server.c.
3885 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Added silc_server_send_notify_invite to send the INVITE
3888 notify between routers.
3890 * Implemented the INVITE command correctly to the server.
3892 * Implemented the INVITE notify type handling in the server.
3894 * Implemented the INVITE command to the client library and on the
3897 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Added function silc_server_get_client_resolve to find the
3900 client entry by ID from all ID lists and then resolve it
3901 (using WHOIS) if it cannot be found. Affected file is
3904 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Implemented the BAN command to the client library.
3908 * The JOIN command in the server now checks the invite list
3911 * Changed the silc_command_reply_payload_encode_va and the
3912 silc_command_payload_encode_va to support that if argument is
3913 NULL it ignores and checks the next argument. Affected file
3914 lib/silccore/silccommand.c.
3916 * Added silc_server_send_notify_ban to send the BAN notify
3917 type between routers.
3919 * Chaned the silc_notify_payload_encode to support that if
3920 argument is NULL it ignores and checks the next argument.
3921 Affected file lib/silccore/silcnotify.c.
3923 * Tested ban lists in router environment successfully.
3925 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Implemented BAN command to the server, in silcd/command.[ch].
3929 * Removed the BAN and INVITE_LIST modes from the CMODE command
3932 * Added function silc_string_match to regex match two strings.
3933 Affected files lib/silcutil/silcutil.[ch].
3935 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Redefined parts of the SilcChannelEntry in the server to support
3938 the new ban and invite lists.
3940 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Redefined the INVITE command. The same command can be used to
3943 invite individuals to the channel but also to manage the invite
3944 list of the channel (to add to and remove from the invite list).
3945 Updated the protocol specs.
3947 * Added new command SILC_COMMAND_BAN that can be used to manage
3948 the ban list of the channel. Updated the protocol specs.
3950 * Removed the channel modes: the SILC_CMODE_BAN and the
3951 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3952 in the CMODE command. The equivalent features are now available
3953 using INVITE and BAN commands. Updated the protocol specs.
3955 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3956 in the network about change in the current ban list. The notify
3957 type is not used by the client.
3959 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3960 support the invite lists.
3962 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Added new function silc_string_regexify that converts string
3965 including wildcard characters into regex string that can
3966 be used by the GNU regex library. Added into the file
3967 lib/silcutil/silcutil.[ch].
3969 Added silc_string_regex_combine to combine to regex strings
3970 into one so that they can be used as one regex string by
3971 the GNU regex library. Added into the file
3972 lib/silcutil/silcutil.[ch].
3974 Added silc_string_regex_match to match two strings. It returns
3975 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3977 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Imported GNU regex to the soruce tree into lib/contrib.
3980 Fixed some compiler warning from the regex.c.
3982 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Fixed MOTD command in the server to work in router environment.
3986 * Fixed the MOTD command in the client library to support
3987 the server argument in the command.
3989 * Added `nickname_len' argument to the silc_idlist_add_client
3990 in the server, as the `nickname' argument may be binary data
3993 * Added silc_idlist_get_channels to return all channels from
3996 * Implemented LIST command to the server. Affected file is
3999 * Implemented the LIST command to the client library and on the
4002 * Added [<user count>] argument to the LIST command reply.
4003 With private channels the user count is not shown.
4005 * Updated TODO and README.
4007 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * The client entry's data.registered must be TRUE even with
4010 global client entry on global client list. The data.registered
4011 is used to check whether the client is anymore in the network,
4012 for example with WHOWAS command so it must be valid.
4014 * Fixed the WHOWAS command in the server. It now actually works
4015 in router environment. Added function into silcd/command_reply.c
4016 silc_server_command_reply_whowas_save.
4018 * Added silc_idlist_purge function to the silcd/idlist.c
4019 to periodically purge the ID Cache.
4021 * Fixed INFO command in the server. It works now in router
4022 environment. Added <server name> argument to the INFO command
4023 reply. Updated the protocol specs.
4025 * Fixed minor bug in silc_idcache_purge to not purge if the
4026 expire value is zero.
4028 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4029 they were buggy because of the WHOWAS information.
4031 * Fixed local command MSG to handle the async resolving of
4032 the remote client properly. It used to fail the first MSG.
4033 Affected file silc/local_command.c.
4035 * Added `data_len' field to SilcIDCache context.
4037 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Update TODO. Todo in commands in the server.
4041 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4044 used by routers as broadcast packet to inform other routers
4045 about the changed user mode.
4047 Implemented the notify handling in the server. Affected file is
4048 silcd/packet_receive.c. Added the function
4049 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4051 * Added new generic Channel Payload and deprecated the New Channel
4052 Payload. The New Channel Payload is now the generic Channel
4055 * Added new argument `mode' to the silc_server_send_new_channel
4056 as it is required in the Channel Payload now.
4058 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4059 and created a new and real SilChannelPayload to represent the
4060 new generic Channel Payload. Implemented the encode/decode
4061 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4063 * Added silc_server_get_client_channel_list to return the list
4064 of channels the client has joined for WHOIS command reply.
4065 Affected file silcd/server.[ch].
4067 * Implemented the channel list sending in the WHOIS command reply
4068 in server and in the client.
4070 Implemented the channel list displaying on the user interface
4071 as well. Affected file silc/client_ops.c.
4073 * Added silc_channel_payload_parse_list to parse list of Channel
4074 Payloads. It returns SilcDList list of SilcChannelPayloads.
4075 Client for example can use this function to parse the list of
4076 channels it receives in the WHOIS command reply. The caller
4077 must free the list by calling silc_channel_payload_list_free.
4078 Affected files lib/silccore/silcchannel.[ch].
4080 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Added one new argument <user mode> to the WHOIS command reply
4083 to return the mode of the user in SILC. Updated the protocol
4086 Implemented it to the server and client.
4088 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Fixed the mode printing on the user interface on joining.
4091 Affected file silc/client_ops.c.
4093 * Implemented the UMODE command and user modes in general to the
4094 client library and to the user interface.
4096 * Implemented the UMODE command to the server.
4098 * The server now sends UNKNOWN_COMMAND error status if client sends
4099 unknown command. Affected file silcd/command.c.
4101 * All server commands now handle the command identifier the right
4102 way when sending the command reply to the client. The client can
4103 use to identify the command replies with the identifier.
4105 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Added silc_server_get_client_route to resolve the route to
4108 the client indicated by the client ID. Affected file is
4111 * Added silc_server_relay_packet as general function to relay
4112 packet to arbitrary destination. This deprecates functions
4113 like _send_private_message_key, _relay_notify etc. Affected
4114 file is silcd/packet_send.[ch].
4116 Removed silc_server_send_key_agreement,
4117 silc_server_send_private_message_key and
4118 silc_server_packet_relay_notify functions from the file
4119 silcd/packet_send.[ch].
4123 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4124 server. Affected file silcd/packet_receive.[ch].
4126 * Implemented the KILL command to the client. Implemented the
4127 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4128 Affected files lib/silcclient/command[_reply].c and
4129 lib/silcclient/client_notify.c. Implemented the KILL notify
4130 printing in the user inteface.
4132 * Fixed a lot silc_parse_nick memory leaks from the client
4133 library in the file lib/silcclient/command.c.
4135 * Changed the silc_server_send_notify_on_channels's `sender'
4136 argument from SilcSocketConnection to SilcClientEntry to
4137 check the sender as entry and not as connection object and not
4138 to send to the client provided as argument. The affected file
4139 is silcd/packet_send.[ch].
4141 * The notify packets that are destined directly to the client used
4142 to not to be processed by the server. Now changed that and the
4143 server processes all notify packets. After relaying the packet
4144 to the client the notify packet is processed in the server.
4146 * The silc_server_free_client_data now checks whether there is
4147 pending outgoing traffic for the client and purges the data to
4148 the network before removing the client entry.
4150 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4153 an client is killed from the SILC Network. Updated the protocol
4156 Added new function silc_server_send_notify_killed to the
4157 silcd/packet_send.[ch].
4159 * Added function silc_server_packet_relay_notify to relay notify
4160 packets that are destined directly to a client. In this case
4161 the server does not process the notify packets but merely relays
4162 it to the client. Affected file silcd/packet_send.[ch].
4164 Added also silc_server_packet_process_relay_notify to check
4165 whereto relay the notify. Affected file is
4166 silcd/packet_receive.[ch].
4168 * Implemented the KILL command to the server.
4172 * Added the backup schema desgined last fall to the protocol
4173 specs for everyone to see. The specification is in the
4174 *-spec-xx.txt draft and the packet type definitions for the
4175 backup routers is in *-pp-xx.txt draft. Thusly, added also
4176 new packet type SILC_PACKET_CELL_ROUTERS.
4178 * A big security problem in the implementation discovered. The
4179 signoff of an client did not cause new channel key generation
4180 which it of course should've done. The channel keys must be
4181 always re-generated when client leaves (or signoffs) the channel.
4182 The silc_server_remove_from_channels funtion now handles
4183 the channel key re-generation.
4185 * Added `sender' argument to the silc_server_send_notify_on_channels
4186 to not to send the client provided as argument. Affected file
4187 silcd/packet_send.[ch].
4189 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Implemented OPER and SILCOPER commands into the server and
4194 * Added silc_auth_verify and silc_auth_verify_data to verify
4195 the authentication directly from the authentication payload.
4196 It supports verifying both passphrase and public key based
4197 authentication. Affected file lib/silccore/silcauth.[ch].
4199 * Added `hash' field to the SilcIDListData structure. It is the
4200 hash negotiated in the SKE protocol. Affected file is
4203 * Slight redesigning of the SilcAuthPayload handling routines.
4204 Do not send SilcPKCS but SilcPublicKey as argument.
4206 * Implemented the public key authentication support to the
4207 serverconfig. The public key is loaded from the provided path
4208 and saved as authentication data to void * pointer. Thus,
4209 changed the unsigned char *auth_data to void *auth_data;
4211 * Fixed SHUTDOWN command to send the reply before the server
4212 is shutdown. :) Affected file silcd/command.c.
4214 * Fixed fatal bug in CONNECT command. The hostname was invalid
4215 memory and server crashed. Affected file silcd/command.c.
4217 * Fixed fatal bug in CLOSE command. The server_entry became
4218 invalid but was referenced later in the command. Affected file
4221 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * Fixed fatal bug in failure packet handling. Server ignored
4224 the failure and thus crashed when it came.
4228 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4231 that the command may be executed only once in (about) 2 seconds.
4232 The old SILC_CF_LAG flag is same but allows command bursts up
4233 to five before limiting.
4235 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4236 server code. Various commands now includes the CF_LAG_STRICT
4237 flag to disallow any kind of miss-use of the command.
4239 * Fixed the silc_buffer_unformat to not to allocate any data
4240 if the length of the data is zero. It used to allocate the
4241 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4243 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Changed the format of AdminConnection configuration section
4246 in the server. Added username of the admin to the format.
4247 Affected files silcd/serverconfig.[ch].
4249 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4250 to return admin configuration data by host, username and/or
4253 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Implemented WHOWAS command to the server. Added the functions:
4257 silc_server_command_whowas_parse,
4258 silc_server_command_whowas_send_reply,
4259 silc_server_command_whowas_from_client and
4260 silc_server_command_whowas_from_server
4262 * Added <Client ID> argument to the WHOWAS command reply. Updated
4263 the protocol specs accordingly.
4265 * Implemented WHOWAS command and command_reply to the client
4268 Implemented the WHOWAS printing on the user interface.
4270 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added new argument to the WHOWAS command reply, the real name.
4273 It is an optional argument. Updated the protocol specs.
4275 * Added SilcIDCacheDestructor callback that is registered when
4276 the SilcIDCache is allocated. The callback is called when
4277 an cache entry in the ID Cache expires, or is purged from the
4278 cache. Added into lib/silccore/idcache.[ch].
4280 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4281 to destruct the client entries when the cache entry expires.
4282 Other ID Cache's in server and in the client library ignores
4285 * If the ID Cache entry's `expire' field is zero then the entry
4286 never expires. Added boolean `expire' argument to the
4287 silc_idcache_add function in the lib/silccore/idcache.[ch].
4288 If it is TRUE the default expiry value is used.
4290 * Added silc_server_free_client_data_timeout that is registered
4291 when client disconnects. By default for 5 minutes we preserve
4292 the client entry for history - for WHOWAS command.
4294 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Added support to the server to enforce that commands are not
4297 executed more than once in 2 seconds. If server receives
4298 commands from client more frequently, timeout is registered
4299 to process the commands. Affected file silcd/command.c.
4300 Added new function silc_server_command_process_timeout.
4302 * Changed NICK_NOTIFY handling in client library to check that
4303 if the client's nickname was changed, so there is no need to
4304 resolve anything from the server.
4306 * Removed error printing from the WHOIS and IDENTIFY commands.
4307 If error occurs then it is ignored silently in the client library.
4308 The application, however, may map the received error to
4309 human readable error string. The application currently maps
4310 the NO_SUCH_NICKNAME error to string.
4312 * Made the command status message public to the application. Moved
4313 them from lib/silcclient/command_reply.c to
4314 lib/silcclient/command_reply.h. The application can map the
4315 received command status to the string with the
4316 silc_client_command_status_message function.
4318 * Added check to the server to check that client's ID is same
4319 as the Source ID in the packet the client sent. They must
4322 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Added dist-bzip hook to the Makefile.am to make bzip2
4325 compressed distributions.
4327 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Server now enforces the maximum length for the nickname and
4330 the channel as protocol specification dictates. 128 bytes for
4331 nickname and 256 bytes for channel name.
4333 * Moved the WHOIS printing to the application. The client libary
4334 does not print out the WHOIS information anymore, the application
4335 must do it. Renamed silc_client_command_reply_whois_print to
4336 the silc_client_command_reply_whois_save.
4338 The client's idle time is also sent to the application now, and
4339 the idle is shown on screen.
4341 * Added silc_client_command_reply_identify_save to save the
4342 received IDENTIFY entries.
4344 * Do not check for channel private keys in message sending and
4345 reception if the channel does not have the PRIVKEY mode set.
4346 Affected file lib/silclient/client_channel.c.
4348 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4351 just surfaced after chaning the JOIN procedure.
4353 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Added silc_client_get_clients_by_list to get client entries
4356 from Client ID list, that is returned for example by JOIN
4357 and USERS command replies. The application should use this
4358 function for example when JOIN command reply is received to
4359 resolve the clients already on the channel (library does not
4360 do that anymore as USERS command reply is not used in the JOIN
4361 procedure anymore). Affected files lib/silcclient/silcapi.h and
4362 lib/silcclient/idlist.c.
4364 * JOIN command reply and USERS command reply returns now SilcBuffer
4365 pointers instead of unsigned char pointers when returning
4366 the client list and mode list.
4368 * Added <Client ID> argument to the JOIN command reply, mainly
4369 for the server to identify for which client the command was
4370 originally sent. Updated protocol specs accordingly.
4372 * Added SilcDlist private_key pointer to the SilcChannelEntry
4373 in the client to support the channel private keys. Affected
4374 file is lib/silcclient/idlist.h.
4376 * Added SilcChannelPrivateKey argument to the function
4377 silc_client_send_channel_message so that application can choose
4378 to use specific private ke if it wants to. If it is not provided,
4379 the normal channel key is used, unless private keys are set.
4380 In this case the first (key that was added first) is used
4381 as the encryption key.
4383 * Implemented the support for channel private key handling.
4384 Implemented the following functions:
4386 silc_client_add_channel_private_key,
4387 silc_client_del_channel_private_keys,
4388 silc_client_del_channel_private_key,
4389 silc_client_list_channel_private_keys and
4390 silc_client_free_channel_private_keys
4392 Affected file lib/silcclient/client_channel.c.
4394 * Added the support for the private keys in the channel message
4395 sending and encryption and in the message reception and
4396 decryption. Affected funtions are
4397 silc_client_send_channel_message and silc_client_channel_message.
4399 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Added SKE's key verify callback to the client library's
4402 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4404 * Removed the statement that server (or router) must send USERS
4405 command reply when joining to the channel so that the client
4406 knows who are on the channel. Instead, the client list and
4407 client's mode list is now sent in the JOIN command reply to the
4408 client who joined channel. This is better solution.
4410 * Added function silc_server_get_users_on_channel and function
4411 silc_server_save_users_on_channel to the silcd/server.[ch].
4413 * Removed function silc_server_command_send_users from the
4416 * Do not show topic on the client library anymore. The topic is
4417 sent in the command reply notify to the application and the
4418 application must show the topic now.
4420 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added client searching by nickname hash into the IDENTIFY and
4423 WHOIS commands in the server as they were clearly missing from
4424 them. Affected file is silcd/command.c.
4426 * Fixed a bug in private message receiving in the client library.
4427 The remote ID was freed and it wasn't supposed, now it is
4430 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Minor fix to the channel payload; allocate the data area, as it
4433 needs to be of specific length.
4435 * If the key agreement port is zero then the operating
4436 system will define the bound port. Affected files are
4437 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4439 * Added new function silc_channel_payload_decrypt into the file
4440 lib/silccore/silcchannel.[ch].
4442 * Moved the channel message etc, check from silc_packet_decrypt
4443 to applications. The library calls now a generic
4444 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4445 when the packet is either normal or special. This was done to
4446 allow more wide range of checking that was not allowed when
4447 the code was in library. Now applications can do virtually any
4448 checks to the packet and return to the library the decision how
4449 the packet should be processed. Affected files are
4450 lib/silccore/silcpacket.[ch].
4452 Added silc_server_packet_decrypt_check to the server and
4453 silc_client_packet_decrypt_check to the client library.
4455 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4456 to send with specified source and destination information.
4458 * Channel message delivery between routers was broken after the
4459 channel key distribution was fixed earlier. The channel key
4460 was used be to distributed to other routers as well which is not
4461 allowed by the protocol. Now this is fixed and channel keys
4462 really are cell specific and the channel message delivery between
4463 routers comply with the protocol specification.
4465 * Fixed various commands in server to check also the global list
4466 for the channel entry and not just the local list. The affected
4467 file silcd/command.c.
4469 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Added assert()s to buffer formatting and unformatting routines
4472 to assert (if --enable-debug) when error occurs. Affected
4473 file: lib/silcutil/silcbuffmt.c.
4475 * Changed to auto-reconnect to check whether the remote host is
4476 router and register the re-connect timeout if it is. It used
4477 to check that whether we are normal server, but router must do
4478 auto-reconnect with another router as well. Affected file
4481 * Removed the [<key len>] option from CMODE command as the cipher
4482 name decides the key length, nowadays. See the defined ciphers
4483 from the protocol specification.
4485 * Added [<hmac>] option to the CMODE command to define the HMAC
4486 for the channel. Added SILC_CMODE_HMAC channel mode.
4488 * Added [<hmac>] option for the JOIN command so that user can
4489 select which HMAC is used to compute the MACs of the channel
4492 * Added Hmac field to the Channel Message Payload. The integrity
4493 of plaintext channel messages are now protected by computing
4494 MAC of the message and attaching the MAC to the payload. The
4495 MAC is encrypted. Now, it is clear that this causes some
4496 overhead to the size of the packet but rationale for this is that
4497 now the receiver can verify whether the channel message decrypted
4498 correctly and also when private keys are set for the channel the
4499 receiver can decrypt the packet with several keys and check from
4500 the MAC which key decrypted the message correctly.
4502 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4503 lib/silccrypt/silccipher.[ch].
4505 * Added silc_hash_len to return the digest length into the
4506 lib/silcrypt/silchash.[ch].
4508 * Rewrote parts of Silc Channel Payload interface in the
4509 lib/silccore/silcchannel.[ch]. The encode function now also
4510 encrypts the packet and parse function decrypts it.
4512 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Fixed a minor formatting bug in the SKE's key material processing.
4515 It actually might have processed the keys wrong way resulting
4518 * Redefined the mandatory HMAC algorithms and added new algorithms.
4519 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4520 and hmac-md5 truncated to 96 bits. The mandatory is now
4521 hmac-sha1-96. Rest are optional (including the one that used
4522 to be mandatory). Rationale for this is that the truncated HMAC
4523 length is sufficient from security point of view and can actually
4524 make the attack against the HMAC harder. Also, the truncated
4525 HMAC causes less overhead to the packets. See the RFC2104 for
4528 * Added new [hmac] configuration section. The SKE used to use
4529 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4530 is of course wrong. The official names that must be proposed in
4531 the SKE are the ones defined in the protocol specification
4532 (hmac-sha1-96 for example). The user can configure any hmac
4533 using any hash function configured in the [hash] section. At
4534 least, the mandatory must be configured.
4536 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4538 * Added HMAC list to the SKE proposal list. It has now both
4539 hash algorithm list and HMAC list. This makes the protocol
4540 incompatible with previous versions. The SKE now seems to work
4541 the way it is supposed to work, for the first time actually.
4543 * Defined plain Hash algorithms to the protocol specification.
4546 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Implemented support for key agreement packets into the server.
4549 Added functions silc_server_key_agreement and
4550 silc_server_send_key_agreement. Other than these functions,
4551 server has nothing to do with this packet.
4553 * Added support for private message key packets into the server.
4554 Added functions silc_server_private_message_key and
4555 silc_server_send_private_message_key.
4559 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4560 called in the protocol's final callback instead in the END
4561 protocol state. This makes a little more sense and in the same
4562 time in client we can use the same protocol routines for normal
4563 key exchange and to key agreement packet handling as well.
4565 * Added to both client's and server's KE protocol context the
4566 SilcSKEKeyMaterial pointer to save the key material. We will
4567 bring the key material to the protocol's final callback by doing
4568 this. The final callback must free the key material.
4570 * Added SKE's packet_send callback into client's KE protocol
4571 context so that the caller can choose what packet sending function
4572 is used. This way we can use different packet sending when
4573 doing normal SKE when doing key agreement packet handling (in
4574 the key agreement packet handling we do not want to encrypt
4577 * Implemented the responder side of the key agreement routines
4578 in the client. The client can now bind to specified port and
4579 accept incoming key negotiation. The key material is passed
4580 to the application after the protocol is over.
4582 * Implemented the processing of incoming Key Agreement packet
4583 in the client. Added function silc_client_key_agreement to
4586 * Implemented the intiator side of the key agreement routines
4587 in the client. The client can now initiate key agreement with
4588 another remote client. The key material is passed to the
4589 application after the protocol is over.
4591 * Created client_keyagr.c to include all the key agreement
4594 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4595 SILC_TASK_CALLBACK except that it is not static.
4597 * Created client_notify.c and moved the Notify packet handling
4598 from the client.[ch] into that file.
4600 * Created client_prvmsg.c and moved all private message and
4601 private message key routines from the client.[ch] into that file.
4603 * Create client_channel.c and moved all channel message and
4604 channel private key routines from the client.[ch] into that file.
4606 * Changed silc_client_get_client_by_id_resolve to resolve with
4607 WHOIS command instead of IDENTIFY command, in the file
4608 lib/silclient/idlist.c.
4610 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Implemented the SKE's responder side to the Client library.
4614 * When FAILURE is received to the protocol do not trust it
4615 blindly. Register a timeout to wait whether the remote closes
4616 the connection as it should do it, only after that process the
4617 actual failure. This was changed to both client and server.
4619 * Added client_internal.h to include some of the structures
4620 there instead of client.h in lib/silcclient/.
4622 * Added function silc_task_unregister_by_callback to unregister
4623 timeouts by the callback function.
4625 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Some "Incomplete WHOIS info" errors has been appearing on the
4628 log files. Took away the entry->userinfo check from WHOIS
4629 reply sending. The entry->userinfo is now " " if client did not
4630 provide one. I thought this was fixed earlier but something
4631 is wrong still. Let's see if the error still appears.
4633 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Fixed a minor bug in the login when the channel key is
4636 re-generated in the server. It used to generate the key in
4637 wrong order and thus caused problems in the channel traffic.
4639 * Fixed a minor bug in channel key distsribution after
4640 KICK command. The key was not sent to the router even though
4643 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added silc_ske_process_key_material_data as generic routine
4646 to process any key material as the SILC protocol dictates. The
4647 function is used by the actual SKE library but can be used by
4648 applications as well. This relates to the private message keys
4649 and the channel private keys since they must be processed the
4650 same way the normal SILC session keys. The protocol dictates
4651 this. Affected files: lib/silcske/silcske.[ch].
4653 Added also silc_ske_free_key_material to free the
4654 SilcSKEKeyMaterial structure.
4656 * Defined silc_cipher_set_key function to set the key for
4657 cipher without using the object's method function. The affected
4658 files: lib/silccrypt/silccipher.[ch].
4660 * Implemented silc silc_client_add_private_message_key,
4661 silc_client_add_private_message_key_ske,
4662 silc_client_del_private_message_key,
4663 silc_client_list_private_message_keys and
4664 silc_client_free_private_message_keys functions in the
4667 Added functions silc_client_send_private_message_key to send
4668 the Private Message Key payload and silc_client_private_message_key
4669 to handle incoming Private Message Key payload.
4671 * Added Cipher field to the Private Message Key payload to set
4672 the cipher to be used. If ignored, the default cipher defined
4673 in the SILC protocol (aes-256-cbc) is used.
4675 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Removed lib/silcclient/ops.h file.
4679 Redefined parts of the SILC Client Library API. Created new
4680 file silcapi.h that deprecates the ops.h file and defines the
4681 published Client Library API. Defined also private message key
4682 API and channel private key API into the file.
4684 This is the file that the application must include from the
4685 SILC Client Library. Other files need not be included by
4686 the application anymore.
4688 * Added new key_agreement client operation callback and also
4689 defined the Key Agreement library API for the application.
4691 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4694 is used by clients to request key negotiation between another
4695 client in the SILC network. If the negotiation is started it
4696 is performed using the SKE protocol. The result of the
4697 negotiation, the secret key material, can be used for example
4698 as private message key.
4700 Implemented the Key Agreement payload into the files
4701 lib/silccore/silauth.[ch].
4703 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Redefined ciphers for the SILC protocol. Added some new ciphers
4706 and defined the key lengths for the algorithms. Changed the
4707 code accordingly. The default key length is now 256 bits.
4709 * Fixed SKE key distribution function silc_ske_process_key_material
4710 when the key length is more than 128 bits. The default key
4711 length in SILC is now 256 bits.
4713 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4714 to indicate unsupported algorithm.
4716 * Renamed rijndael.c to aes.c and all functions as well.
4718 * Fixed a long standing channel key setting bug in client library.
4719 Weird that it has never surfaced before.
4721 * Fixed bug in channel deletion. If the entire channel is removed
4722 then it must also delete the references of the channel entry
4723 from the client's channel list as the client's channel entry and
4724 the channel's client entry share same memory.
4726 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Implemented CONNECT and SHUTDOWN commands in the client.
4730 * Implemented CLOSE command to the client.
4732 * Added the function silc_idlist_find_server_by_name into the
4733 files silcd/idlist.[ch].
4735 Added the function silc_idlist_find_server_by_conn into the
4736 files silcd/idlist.[ch].
4738 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * DIE command was renamed to SHUTDOWN. Updated the both code
4743 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4744 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4746 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4749 * Added function silc_server_create_connection function to create
4750 connection to remote router. My server implementation actually
4751 does not allow router to connect to normal server (it expects
4752 that normal server always initiates the connection to the router)
4753 so the CONNECT command is only good for connecting to another
4756 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4758 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4759 or some other client was kicked from the channel.
4761 Implemented the handling of the notify type to both client
4764 Implemented silc_server_send_notify_kicked to send the KICKED
4765 notify. It is used to send it to the server's primary router.
4767 * Implemented the KICK command into server and client.
4769 * Added `query' argument to the silc_idlist_get_client function
4770 to indicate whether to query the client from server or not if
4773 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4774 to indicate that the client is not channel founder.
4778 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Removed the rng context from SilcPacketContext structure and
4781 changed that the packet routine uses the Global RNG API.
4783 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Added support for quit message that client can "leave" on the
4786 channel when it quits the SILC. It is ditributed inside the
4787 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4789 Added silc_server_free_client_data that will take the
4790 signoff message as argument.
4792 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4794 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Updated parts of the protocol specification to keep it up
4799 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4802 payloads in one packet.
4804 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4805 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4806 use now the new List flag.
4808 * Also deprecated the following packet types: REPLACE_ID,
4809 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4811 * Added list support for Notify packet in server.
4813 * Added silc_server_send_notify_channel_change to send the
4814 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4815 the silc_server_send_replace_id.
4817 * Added silc_server_send_notify_nick_change to send the
4818 NICK_CHANGE notify type. Deprecates the function
4819 silc_server_send_replace_id.
4821 * Added silc_server_send_notify_join to send the JOIN notify type.
4822 Deprecates the function silc_server_send_new_channel_user.
4824 * Added silc_server_send_notify_leave to send LEAVE notify type.
4825 Deprecates the function silc_server_send_remove_channel_user.
4827 * Added silc_server_send_notify_cmode and
4828 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4829 types. Deprecates the silc_server_send_set_mode function.
4831 * Added SERVER_SIGNOFF notify type to indicate that server has
4832 quit. This means that all clients on the channel from that
4833 server will drop. This can be also used when netsplit happens.
4835 Deprecated REMOVE_ID packet type since it is not needed anymore
4838 Added silc_server_send_notify_server_signoff to send the
4839 SERVER_SIGNOFF notify type. Deprecates the function
4840 silc_server_send_remove_id.
4842 Added also silc_server_send_notify_signoff to send the
4843 SIGNOFF notify type.
4845 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4846 SILC protocol from this day on. Changed the protocol
4847 specification as well.
4849 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4850 notify type. It is used between routers to notify about
4851 topic changes on a channel.
4853 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4856 * Partly updated the protocol specification to comply with the
4857 changes now made. It is still though a bit outdated.
4859 * The JOIN notify type now takes one extra argument <Channel ID>.
4860 The packet used to be destined to the channel but now the
4861 JOIN type may be sent as list thus it is impossible to
4862 destine it to any specific channel. By adding this argument
4863 it is again possible.
4865 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Added CREDITS file. The CHANGES and CREDITS file will appear
4868 in the distribution as well.
4870 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4873 types in the server's silcd/packet_receive.c.
4875 * Implemented CMODE and CUMODE to work in router environment.
4877 * Fixed minor encoding and decoding buglet from the
4878 lib/silccore/silcmode.c.
4880 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4883 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4885 * Changed all SilcConfigServer* and silc_config_server* to
4886 SilcServerConfig* and silc_server_config*, respectively.
4889 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Associated the ID (client or server ID) to the Authentication
4892 Payload to avoid any possibility of forging. Updated the
4893 protocol specification and the code accordingly.
4895 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * The RSA key length is now save to the RsaKey context in the
4898 key generation process in lib/silccrypt/rsa.c. The key length
4899 is now used to figure out the maximum size of the block allowed
4900 to be encrypted/signed.
4902 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4903 is equivalent to the silc_mp_mp2bin but does not allocate any
4906 * Changed silc_mp_mp2bin API to take length argument. If it is
4907 non-zero then the buffer is allocated that large. If zero, then
4908 the size is approximated using silc_mp_sizeinbase, which however
4911 * Created Global RNG API which is global RNG that application can
4912 initialize. After initializing, any routine anywhere in the
4913 code (including library) can use RNG without allocating a new
4914 RNG object. This was done to allow this sort of use of the
4915 RNG in code that has no chance to allocate RNG object. All
4916 applications currently allocate this and many routines in the
4917 library use this. Affected file lib/silccrypt/silcrng.[ch].
4919 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4920 it to use the Global RNG API.
4922 * Defined Authentication Payload into protocol specification that
4923 is used during SILC session to authenticate entities. It is
4924 used for example by client to authenticate itself to the server
4925 to obtain server operator privileges.
4927 Implemented this payload into the lib/silccore/silcauth.[ch].
4928 Implemented also routines for public key based authentication
4929 as the new protocol specification dictates.
4931 Moved definitions of different authentication methods from
4932 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4934 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4935 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4936 silc_pkcs_verify_with_hash functions into the file
4937 lib/silccrypt/silcpkcs.[ch].
4939 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * The client entry's userinfo pointer must be always valid.
4942 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4943 will fail since it requires the userinfo. Now, the userinfo
4944 is allocated as "" if actual userinfo does not exist. Actually,
4945 it must exist and it is totally Ok to drop client connections
4946 that does not announce the userinfo. However, we will make
4947 this workaround for now.
4949 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4950 to return the remote port by socket.
4952 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4955 SILC_SERVER_PENDING_EXEC and added an new macro
4956 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4957 data or when error occurs while processing the pending command.
4959 Added new argument `destructor' into silc_server_command_pending
4960 and to the SilcServerCommandPending object. This destructor is
4961 now called after calling the pending callback or if error occurs
4962 immediately. If error occurs the actual pending callback won't
4963 be called at all - only the destructor. The destructor may be
4964 NULL if destructor is not needed.
4966 All this applies for client library code as well. Similar
4967 changes were made there as well for the pending commands.
4969 In the client, the application must now allocate the
4970 SilcClientCommandContext with the silc_client_command_alloc
4973 * Added reference counter to the SilcServerCommandContext. Added
4974 function silc_server_command_alloc and silc_server_command_dup
4977 Same type of functions added to the client library for the same
4980 * Removed the cmd_ident from IDListData away since it is now
4981 global for all connections. It is the command identifier used
4982 in command sending and with pending commands. The affected file
4985 * Added reference counter to the SilcSocketConnection objecet to
4986 indicate the usage count of the object. The object won't be
4987 freed untill the reference counter hits zero. Currently only
4988 server uses this, and client ignores it. The client must be
4989 set to use this too later. The affected files are
4990 lib/silccore/silcsockconn.[ch]. Added also the function
4991 silc_socket_dup to increase the reference counter.
4993 This was mainly added because it is possible that the socket
4994 is removed underneath of pending command or other async
4995 operation. Now it won't be free'd and proper DISCONNECTING
4996 flags, etc. can be set to avoid sending data to connection that
4997 is not valid anymore.
4999 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5000 the connection. After that it sets SILC_SET_DISCONNECTED.
5001 It is, however, possible that the socket data is not still freed.
5002 The silc_server_packet_process now checks that data is not
5003 read or written to connection that is DISCONNECTED. The socket
5004 get's freed when the reference counter hits zero.
5006 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Changed the client operation API: channel_message operation's
5009 `sender' is now the client entry of the sender, not the nickname
5010 and the `channel' is the channel entry, not the channel name.
5012 In the private_message operation the `sender' is now also the
5013 client entry of the sender not the nickname.
5015 Affected file is lib/silcclient/ops.h and all applications
5016 using the client operations.
5018 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Moved the calling of ops->connect() from connect_to_server_final
5021 into receive_new_id functin since that is the point when the
5022 client is actually allowed to send traffic to network. The
5023 affected file is lib/silcclient/client.c.
5025 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5028 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5029 (if needs broadcasting) instead of broadcasting the packets one
5030 by one which would make a burst in the network traffic.
5032 * Added `broadcast' argument to the functions in silcd/server.[ch]
5033 silc_server_create_new_channel[_with_id] to indicate whether
5034 to send New Channel packet to primary router.
5036 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Added new function into the silcd/server.[ch] files:
5039 silc_server_create_new_channel_with_id to create new channel with
5040 already existing Channel ID.
5042 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5043 lib/silccore/silcpacket.h. This packet is used t send list of
5044 Set Mode payloads inside one packet. Server uses this to set
5045 the modes for the channels and clients on those channels, that it
5046 announced to the router when it connected to it. The protocol
5047 specification has been updated accordingly.
5049 * The silc_server_new_channel did not handle the packet coming
5050 from normal server as it normally does not send that. However,
5051 when it announces its channels it does send it. Implemented
5052 the support for that.
5054 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5055 into the file lib/silccore/id.h.
5057 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Fixed memory leaks in the functions silc_idlist_del_client,
5060 silc_idlist_del_channel and silc_idlist_del_server in the file
5061 silcd/idlist.c. All of those leaked like a sieve.
5063 * Fixed some small memory leaks in the client's function
5064 silc_client_notify_by_server.
5066 * Added functions into silcd/server.c: silc_server_announce_clients,
5067 silc_server_announce_channels and silc_server_announce_server.
5068 These functions are used by normal and router server to announce
5069 to its primary router about clients, channels and servers (when
5070 router) that we own. This is done after we've connected to the
5073 These functions effectively implements the following packet types:
5074 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5075 and SILC_PACKET_NEW_ID_LIST.
5077 * Added new functions into the silcd/packet_receive.[ch]:
5078 silc_server_new_id_list, silc_server_new_channel_list and
5079 silc_server_new_channel_user_list to handle the incoming
5080 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5082 * Added support of changing Channel ID in the function
5083 silc_server_replace_id. If the server that announces a channel
5084 to the router already exists in the router (with same name but
5085 with different Channel ID), router is responsible to send
5086 Replace ID packet to the server and force the server to change
5087 the Channel ID to the one router has.
5089 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5090 client that the Channel ID has been changed by the router. The
5091 normal server sends this to the client. Client must start using
5092 the new Channel ID as the channel's ID.
5094 Implemented handling of this new type into lib/silcclient/client.c
5095 into the function silc_client_notify_by_server.
5097 * Added new function silc_idlist_replace_channel_id into the files
5098 silcd/idlist.[ch] to replace the Channel ID.
5100 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Call silc_server_command_identify_check always when processing
5103 the IDENTIFY command in silcd/command.c
5105 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5108 send keepalive packets. The packet can be sent by clients,
5109 servers and routers.
5111 Added function silc_socket_set_heartbeat into the file
5112 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5113 If not set, the heartbeat is not performed. The actual
5114 heartbeat is implemented in the low level socket connection
5115 library. However, application is responsible of actually
5118 Added silc_server_send_heartbeat to send the actual heartbeat
5119 packet into silcd/packet_send.[ch]. Server now performs
5120 keepalive with all connections.
5122 * Added silc_task_get_first function into lib/silcutil/silctask.c
5123 to return the timeout task with shortest timeout. There was a bug
5124 in task unregistration that caused problems. TODO has been
5125 updated to include that task system must be rewritten.
5127 * The client library will now resolve the client information when
5128 receiving JOIN notify from server for client that we know but
5129 have incomplete information.
5131 * Rewrote parts of silc_server_remove_from_channels and
5132 silc_server_remove_from_one_channel as they did not remove the
5133 channel in some circumstances even though they should've.
5135 * Encryption problem encountered in server:
5137 The LEAVE command used to send the Channel Key packet to the
5138 router immediately after generating it. However, the code
5139 had earlier sent Remove Channel user packet but not immediately,
5140 ie. it was put to queue. The order of packets in the router
5141 was that Channel Key packet was first and Remove Channel User
5142 packet was second, even though they were encrypted in the
5143 reverse order. For this reason, MAC check failed. Now, this
5144 is fixed by not sending the Channel Key packet immediately but
5145 putting it to queue. However, this is more fundamental problem:
5146 packets that are in queue should actually not be encrypted
5147 because packets that are sent immediately gets encrypted
5148 actually with wrong IV (and thus MAC check fails). So, packets
5149 that are in queue should be encrypted when they are sent to
5150 the wire and not when they put to the queue.
5152 However, the problem is that the current system has not been
5153 designed to work that way. Instead, the packet is encrypted
5154 as soon as possible and left to the queue. The queue is then
5155 just purged into wire. There won't be any fixes for this
5156 any time soon. So, the current semantic for packet sending
5159 o If you send packet to remote host and do not force the send
5160 (the packet will be in queue) then all subsequent packets to the
5161 same remote host must also be put to the queue. Only after the
5162 queue has been purged is it safe again to force the packet
5165 o If you send all packets immediately then it safe to send
5166 any of subsequent packets through the queue, however, after
5167 the first packet is put to queue then any subsequent packets
5168 must also be put to the queue.
5170 Follow these rules and everything works fine.
5172 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Added new function silc_server_remove_clients_by_server to
5175 remove all client entries from ID list when the server connection
5176 is lost. In this case it is also important to invalidate all
5177 client entires as they hold the invalid server entry. This
5178 fixes fatal bug when server has lost connection and will reconnect
5181 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Made some sanity checks to silc_server_daemonise like to check
5184 whether the requested user and group actually exists.
5186 * Added sanity check to SKE's silc_ske_responder_finish to check
5187 that the public and private key actually is valid.
5189 * Invalidate the client's nickname when receiving Replace ID
5190 packet and the Client ID is being replaced. This means that the
5191 server will query the nickname if someone needs it (client)
5194 * Sort the ID Cache in client library when the ID Cache data
5195 has changed (needs sorting).
5197 * Do not allow for SILC client to create several connections to
5198 several servers. The client does not support windows right now
5199 and generating multiple connections causes weird behaviour.
5201 Irssi-silc client does support windows and can handle several
5202 connections without problems, see: www.irssi.org and SILC plugin.
5204 * Fixed some places where client was added to the IDList. The
5205 rule of thumb is following (in order to get everything right):
5206 If the client is directly connected local client then the
5207 `connection' argument must be set and `router' argument must be
5208 NULL to silc_idlist_add_client function. If the client is not
5209 directly connected client then the `router' argument must
5210 bet set and the `connection' argument must be NULL to the
5211 silc_idlist_add_client function.
5213 * The funtion silc_server_packet_send_local_channel actually did
5214 not check whether the client was locally connected or not. It
5215 does that now. Fixed a bug related to LEAVE command.
5217 * Fixed Remove Channel User payload parsing bug in server's
5218 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5220 * The server's silc_server_save_channel_key now checks also the
5221 global ID list for the channel as it might not be in the local
5222 list. Fixed a bug related to LEAVE command.
5224 * Is this the end of the [<unknown>] buglet that has been lurking
5225 around for a long time? A little for loop fix in server's
5226 silc_server_command_whois_parse that is used by both IDENTIFY
5227 and WHOIS command. At least, this was a clear bug and a cause
5228 of one type of [<unknown>] buglet.
5230 * WHOIS and IDENTIFY commands call the function
5231 silc_server_command_[whois/identify]_check function even if
5232 we are not router server.
5234 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added --with-gmp configuration option. If set the GMP
5237 is always compiled in the SILC source tree. If not set then
5238 it is checked whether the system has the GMP3 installed. If
5239 it has then the GMP won't be compiled (the system's headers
5240 and library is used), if it doesn't have it then the GMP is
5241 compiled in the SILC source tree.
5243 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Changed RSA private exponent generation to what PKCS #1
5246 suggests. We try to find the smallest possible d by doing
5247 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5248 not security fix but optimization.
5250 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Added new config entry [Identity] to fork the server and run
5253 it as specific user and group. A patch from Bostik.
5255 * Imported Dotconf configuration library into lib/dotconf.
5256 This will be used to create the SILC configuration files later.
5257 It will appear in the distsribution after this commit.
5259 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * A big code auditing weekend happening. Auditing code for
5262 obvious mistakes, bugs and errors. Also, removing any code
5265 Removed files for being obsolete:
5267 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5268 inline in the file lib/silcutil/silcbuffer.h)
5270 o lib/silcutil/silcbufutil.c (the header has inline versions)
5272 Changed code to fix possible error conditions:
5274 o The buffer formatting routines now check that the destination
5275 buffer really has enough space to add the data. This applies for
5276 both buffer formatting and unformatting
5277 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5278 unformatting was changed to accomodate following rules:
5279 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5280 sent to the function while XXX_*STRING will not allocate or copy
5281 the data into the buffer. Instead it sets the pointer from the
5282 buffer into the pointer sent as argument (XXX_*STRING used to
5283 require that the pointer must be allocated already). This change
5284 makes this whole thing a bit more consistent and more optimized
5285 (note that the data returned in the unformatting with XXX_*STRING
5286 must not be freed now). The routines return now -1 on error.
5288 o Tried to find all code that use buffer_format and buffer_unformat
5289 and added return value checking to prevent formatting and
5290 especially unformatting errors and possible subsequent fatal
5293 o Changed ske->x and ske->KEY to mallocated pointers in
5294 lib/silcske/silcske.h. Fixed possible data and memory leak.
5296 o Added return value checking to all *_parse* functions. Fixed
5297 many memory leaks as well.
5299 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5300 so that buffer overflows would not happen. All code now also
5301 checks the return value as it can fail.
5303 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Added reconnection support to server if the normal server looses
5306 its connection to the router (for example if router is rebooted).
5307 The server performs normal reconnection strategy implemented
5308 to the server. Affected file silcd/server.c.
5310 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added new packet type SILC_PACKET_SET_MODE that is used to
5313 distribute the information about changed modes (for clients,
5314 channels and clients channel modes) to all routers in the
5315 network. Updated the protocol specification accordingly.
5317 Added functions into silcd/packet_send.c and
5318 silcd/packet_receive.c: silc_server_send_set_mode,
5319 silc_server_set_mode.
5321 Added new files silcmode.[ch] into lib/silccore that implements
5322 the encoding and decoding of Set Mode Payload. Added new type
5323 SilcSetModePayload. Moved the definitions of different modes
5324 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5326 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Oops, a little mistake in server's connection authentication
5329 protocol. The protocol is not ended with FAILURE but with
5330 SUCCESS if the authentication is Ok. :) Affected file is
5333 * Implemented NICK_CHANGE notify handling in server in the file
5334 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5335 the local clients on the channel. After the changing nickname
5336 in router environment snhould work and the [<unknown>] nickname
5337 should appear no more.
5339 The silc_server_replace_id function that receives the Replace ID
5340 payload now sends the NICK_CHANGE notify type also in the file
5341 silcd/packet_receive.c
5343 * Changed WHOIS and IDENTIFY command to support the maximum amount
5344 of arguments defined in protocol specs (3328 arguments). This
5345 fixed a bug that caused problems when there were more than three
5348 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Added extra parameter, command identifier, to the
5351 silc_client_send_command so that explicit command identifier
5354 Changed that ID list routines uses specific command identifier
5355 when sending WHOIS/IDENTIFY requests to the server so that they
5356 can be identified when the reply comes back.
5358 Affected files lib/silcclient/command.[ch],
5359 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5361 * Added `sender' argument to silc_server_packet_send_to_channel
5362 to indicaet the sender who originally sent the packet to us
5363 that we are now re-sending. Ignored if NULL. Affected file
5364 silcd/packet_send.[ch].
5366 * Added some server statistics support in silcd/server_internal.h
5367 SilcServerStatistics structure and around the server code. Also
5368 send some nice statistics information when client is connecting
5371 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Fixed channel ID decoding in server's JOIN command reply in
5374 silcd/command_reply.c
5376 * Fixed braodcasting of replace ID payload to not to send it if
5377 we are standalone server in silcd/packet_receive.c.
5379 * Fixed all channel message sending routines to not to send
5380 packets to clients that has router set, since they are routed
5381 separately in the same function earlier. Affects file
5382 silcd/packet_send.c and all channel packet sending functions.
5384 * In USERS reply, res_argv[i] are not allocated, the table
5385 is allocated. Thus changed that free the table, not its
5388 * In server's whois_check and identify_check if the client is
5389 locally connected do not send any WHOIS commands - they are not
5392 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Fixed some minor bugs in client when sending WHOIS command. The
5395 arguments was in wrong order.
5397 * Removed statis function add_to_channel from server in
5398 silcd/command.c that was previously used with the joining but
5401 * Tested USERS command in router environment successfully with two
5402 routers, two servers and two clients.
5404 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Reorganized the USERS command and command reply in client library
5407 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5408 When the command is given by user we register a pending command
5409 callback that will reprocess the command after the reply has been
5410 received from the server. When reprocessing the packet we then
5411 display the information. Thus, the USERS information is displayed
5412 now in the command callback instead of in the command reply
5413 callback. The processing of the command is same as previously
5414 when server has sent the command reply in the JOINing process.
5416 * Added to USERS command in silcd/command_reply.c to join the client,
5417 we didn't use to know about, to the channel after we've created
5418 a client entry for it. Also, for clienet we did know already still
5419 check whether it is on the channel or not and add it if not.
5421 * Removed silc_server_command_join_notify as the function and its
5424 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Changed the client's pending command handling to the same as the
5427 server's pending command handling. It is also now possible to
5428 execute command reply functions from other command reply
5429 function as the function callbacks for commands and command
5430 replies are one and same. The pending commands are not static
5431 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5432 in client connection context. Thus, pending commands are server
5433 connection specific as it is convenient.
5435 Changed the function silc_client_command_pending and
5436 silc_client_command_pending_del and added new function
5437 silc_client_command_pending_check. Removed the
5438 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5441 * Added cmd_ident, current command identifier, to the client
5442 connection context in lib/silcclient/client.h to keep track on
5443 command identifiers used in command sending. Client's command reply
5444 function handling now supports the mandatory command identifiers.
5446 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5447 funtions in client to fully support pending command callbacks.
5449 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5450 as one of the arguments to the application in the command reply
5453 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5454 before first releasing SILC but came back. Now it is removed again
5455 and should come back nomore. The FORWARDED flag was used only
5456 by the JOINing procedure by forwarding the command packet to router.
5457 Now, the JOINing procedure has been changed to more generic (due
5458 to various router environment issues) and FORWARDED is not needed
5459 anymore for anything. The protocol specification is yet to be
5462 Now, removed silc_server_packet_forward from server and the flag
5463 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5465 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Renamed NAMES command to USERS command. The NAMES was named that
5468 due to historical reasons. Now it is renamed. Also, rewrote
5469 parts of the USERS command. The nickname list is not sent anymore
5470 by the server. Only Client ID and mode lists are sent in the USERS
5471 command. Changed this also to the protocol specification.
5473 The client now resolves the names and stuff after it receives
5474 the USERS list from the server when joining to the channel.
5476 * WHOIS and IDENTIFY commands has been changed to support multiple
5477 Client ID's per command. One can now search for multiple users
5478 in the network by sending only one WHOIS or IDENTIFY command.
5479 Changed the code and the protocol specifications.
5481 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5482 uses silc_server_command_whois_parse to parse the request. */
5484 * If normal server, do not parse the WHOIS and IDENTIFY requests
5485 before sending it to the router. Saves some time.
5487 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Fixed JOIN command on client library. Wrong number of arguments
5490 used to crash the client.
5492 * Added silc_server_channel_has_global function to check whether
5493 channel has global users or not.
5495 * Added silc_server_channel_has_local function to check whether channel
5496 has locally connected clients on the channel.
5498 * The silc_server_remove_from_one_channel now checks whether the
5499 channel has global users or not after given client was removed from
5500 the channel. It also checks whether the channel has local clients
5501 on the channel anymore. If it does not have then the channel entry
5502 is removed as it is not needed anymore.
5504 * The silc_server_notify now checks on JOIN notify whether the joining
5505 client is one of locally connected or global. If it is global then
5506 the channel has now global users on the channel and that is marked
5507 to the channel entry. Also, it now saves the global client to
5508 global list who is joining and JOINs it to the channel. This is
5509 for normal server, that is.
5511 Changed silc_server_send_notify_on_channel,
5512 silc_server_packet_relay_to_channel and
5513 silc_server_packet_send_to_channel check if we are normal server
5514 and client has router set (ie. global client) do not send the
5515 message to that client, as it is already routed to our router.
5517 * Implemented LEAVE notify type handling in silc_server_notify
5520 * Tested LEAVE command in router environment successfully. Tested
5521 with two routers, two servers and two clients.
5525 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5527 * Implemented SIGNOFF notify type handling in silc_server_notify
5530 * silc_server_remove_id now removes the client entry from all channels
5531 it has joined and thusly sends SIGNOFF notify type.
5533 * Rewrote the NAMES list generation in server by removing two excess
5534 loops. The lists are created now inside one loop.
5536 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * silc_server_remove_channel_user checks now also global list
5539 for channel and client.
5541 * silc_server_new_channel_user checks now both local and global
5542 list for channel and client. Fixed a bug in client id decoding.
5543 Used to decode wrong buffer.
5545 * silc_server_channel_message checks now both local and global
5546 list for channel entry.
5548 * Tested channel joining (hence JOIN) in router environment
5549 successfully. Tested with two routers, two servers and two
5552 * Tested channel message sending in router environment successfully.
5554 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Added silc_server_save_channel_key into server.[ch] to save the
5557 received channel key in Channel Key payload processing. It is
5558 also used in JOIN command reply handling.
5560 Equivalent function silc_client_save_channel_key added into
5561 client.[ch] into client library.
5563 * Changed JOIN command reply to send information whether the channel
5564 was created or not (is existing already) and the channel key
5565 payload. Changed protocol specs accordingly.
5567 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5568 the request was sent by ID and not by nickname. Crashed on
5571 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5574 now correctly save the received data.
5576 * silc_server_free_sock_user_data now notifies routers in the
5577 network about entities leaving the network.
5579 At the same time implemented functions silc_server_remove_id
5580 and silc_server_send_remove_id to receive and send REMOVE_ID
5581 packets. The packet is used to notify routers in the network
5582 about leaving entities. The ID removed will become invalid in
5585 * Added function silc_idlist_del_server into server. Removes and
5586 free's server entry from ID list.
5588 * silc_server_private_message function now checks, if we are router,
5589 that the destination ID really is valid ID, naturally.
5591 * In router when NEW_ID packet is received (for new client) the
5592 hash of the Client ID is saved in the ID Cache but the
5593 client->nickname is set to NULL, instead of putting the hash
5596 IDENTIFY command now also checks that client->nickname must be
5597 valid. If it is not if will request the data from the server who
5598 owns the client. Added new function
5599 silc_server_command_identify_check.
5601 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5602 to set the command to already allocated Command Payload.
5604 * Tested private message sending in router environment with two
5605 routers, two servers and two clients. Fixed minor bugs and now
5608 * Fixed segfault from client's NAMES command. Used to crash if
5611 * Forwarded packets must not be routed even if it is not destined
5612 to the receiver. Changed server code comply with this.
5614 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added `require_reverse_mapping' boolean value to ServerParams
5617 structure. If TRUE (not default) the server will require that
5618 the connecting host has fully qualified domain name.
5620 If the reverse mapping is not required and hostname could not be
5621 found the IP address is used as hostname.
5623 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Implemented version string checking to both client and server.
5626 The check is incomplete currently due to the abnormal version
5627 strings used in development version of SILC.
5629 * Changed all command functions in server to use the new
5632 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Changed char *data to unsigned char *data in ID Cache system to
5635 support binary data as ID Cache data. Changed code to support
5636 binary data in lib/silccore/idcache.c.
5638 * Renamed silc_server_packet_relay_command_reply to
5639 silc_server_command_reply as it is normal packet receiving
5640 function. Rewrote the function to accept command replys for
5641 servers and not only for clients.
5643 * Mark remote router always as registered server if we are connecting
5644 to it. Otherwise, commands sent by the router to us are ignored.
5646 * All ID List find routines now returns the ID Cache Entry pointer
5647 as well if requested.
5649 * WHOIS command works now in router environment, tested with two
5650 routers, two servers and two clients.
5652 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5653 in router environment (as it is almost equivalent to WHOIS) but
5654 hasn't been tested thoroughly. Added new functions:
5656 silc_server_command_identify_parse
5657 silc_server_command_identify_send_reply
5658 silc_server_command_identify_from_client
5659 silc_server_command_identify_from_server
5661 * Disabled route cache adding because adding two different ID's with
5662 same IP replaces the old cache entry thus giving wrong route.
5663 The entry->router->connection is always the fastest route anyway
5664 so route cache may not be needed. Of course, new routes maybe
5665 established after receiving the ID when the entry->router->connection
5666 might not be anymore the most optimal.
5668 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Add route cache for received ID for fast routing.
5672 * Added silc_server_packet_route to route received packet on router
5673 that is not destined to us.
5675 * Renamed silc_server_get_route to silc_server_route_get.
5677 * Added id_string and id_string_len fields into SilcServer to
5678 include encoded ServerID for fast comparing without excess
5679 encoding of the ID's.
5681 * Cleaned up WHOIS command on server side. Added following static
5684 silc_server_command_whois_parse
5685 silc_server_command_whois_check
5686 silc_server_command_whois_send_reply
5687 silc_server_command_whois_from_client
5688 silc_server_command_whois_from_server
5690 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5691 arguments in command replies. All command functions should be
5692 updated to use this macro.
5694 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Minor typo fixes on command reply handling on server.
5698 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Added silc_server_command_add_to_channel internal routine to add
5701 the client to the channel after router has created the channel and
5702 sent command reply to the server.
5704 * Added generic silc_server_send_command to send any command from
5707 * Use static buffer with ID rendering instead of duplicating data.
5709 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Fixed a channel user mode bug when joining to a channel server gave
5712 everybody channel founder rights, oops.
5714 * We mark ourselves as the router of the incoming server connection
5715 if we are router ourselves. This way we can check in some packet
5716 sending functions whether it is locally connected server. For
5717 incoming router connections we put NULL.
5719 * For router sending packets locally means now always sending the
5720 packet cell wide; to local clients and local servers. For normal
5721 server sending packet locally means sending it to only local
5724 * Fixed the JOIN command to really work in router environment. If the
5725 channel is created it is always created by the router. Router is
5726 also responsible of making the initial joining to the channel,
5727 sending JOIN notify to the sending server and distributing
5728 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5729 does not exist server doesn't do anything else but forward the
5730 command to the router which performs everything.
5732 * Added silc_server_send_channel_key function to send the Channel Key
5735 * Added silc_server_create_channel_key to create new channel key. The
5736 channel key is now re-generated everytime someone joins or leaves
5737 a channel, as protocol dictates. Note: channel->key_len is the
5740 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5743 packet_receive.[ch] to separate packet sending and receiving
5744 routines. The server.[ch] now includes everything else including
5745 actual packet processing (writing and reading data) and other
5748 Renamed silc_server_private_message_send_internal to
5749 silc_server_send_private_message. The routine is still though
5750 used only to relay private messages as server does not send
5751 private messages itself.
5753 Renamed silc_server_new_channel to silc_server_create_new_channel
5754 and added new function sicl_server_new_channel that handles the
5755 incoming New Channel packet. Added also new sending function
5756 silc_server_send_new_channel to send New Channel Payload.
5758 * Added new function silc_server_notify to process incoming notify
5759 packet to the server/router. Server may then relay the notify
5760 to clients if needed.
5762 * Added new function silc_server_new_channel_user to process incoming
5763 New Channel User packet. Router will redistribute the packet and
5764 send JOIN notify to its local clients and locally connected servers
5765 if needed. Normal server will send JOIN notify to its local client
5766 on same channel when received this packet. Added also corresponding
5767 sending function silc_server_send_new_channel_user to sent the
5770 * Added boolean route argument to send_notif_to_channel and
5771 packet_send_to_channel functions to attempt to route the packet
5772 if it is TRUE and send only locally if it is FALSE.
5774 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * silc_server_replace_id now broadcasts the received replace ID
5777 packet if it is not broadcast packet already. The router must
5778 broadcast to inform other routers about changed ID.
5780 * Added backpointer to server's router into SilcServer context in
5781 silcd/server_internal.h.
5783 * Fixed silc_server_packet_broadcast to send correct broadcast
5786 * The channel key is now distributed to the local client as soon
5787 as it is received from the router (in router environment) so that
5788 no other packet may be sent for the channel until client has
5791 * silc_server_remove_channel_user now broadcasts the received
5792 Remove Channel User packet if it is not broadcast packet already.
5793 The router must broadcast to inform other routers about removed
5796 * Added users field into SilcPacketContext that is a reference count
5797 of the context. One can increase the reference count by calling
5798 silc_packet_context_dup which is now changed to just increase the
5799 reference count instead of duplicating the data. The reference
5800 count is decresed by calling silc_packet_context_free that will
5801 free the data after the reference count hits zero.
5803 For now on the packet context and everything allocated into it
5804 (including the raw packet from network) must be freed by calling
5805 the new silc_packet_context_free function. Added also new function
5806 silc_packet_context_alloc that must be used now to allocate the
5807 context. This also means that if a routine is asynchronous from
5808 silc_[client/server]_packet_parse_type the packet context must
5809 be duplicated by calling silc_packet_context_dup. Otherwise it
5810 gets free'd after silc_[client/server]_packet_parse_type returns.
5811 Also, one must remember that if packet is duplicated then its
5812 reference count must be decresed by calling the free function as
5813 many times as it was duplicated.
5815 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5816 from both client and server.
5818 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Made joining to a channel working in router environment.
5822 * Cleaned up JOIN command on server side and create function
5823 silc_server_command_join_channel internal routine to make the
5826 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Changed silc_command_pending list to SilcDList. Also, added
5829 `ident' field to SilcServerCommandPending structure to identify
5830 the reply and to call correct callback.
5832 Added silc_server_command_pending_check function to replace the
5833 corresnponding macro. The silc_command_pending list is not
5836 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5837 to set identifier to previously allocated Command Payload. It
5838 is used to set identifier for command when resending Command
5841 * Added silc_command_payload_encode_payload to encode Command
5842 Payload buffer from SilcCommandPayload structure.
5844 * Added silc_argument_payload_encode_payload to encode Argument
5845 payload buffer from SilcArgumentPayload structure.
5847 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Changed WHOIS command to support router connection on server side.
5850 The whois request is always sent to router unless the server is
5851 standalone server. After server has received the reply from the
5852 router will it send the reply to the client.
5854 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5855 broadcast received broadcast packet. The function is used only
5856 by router. The broadcast packet is always sent to the router's
5859 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5860 render given ID to printable string, for log files for example.
5862 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Made basic router to router connections working. At least they
5865 can now connect to each other but nothing really works the way
5866 they are supposed - yet.
5868 * Added new initiator token to RouterConnection configuration
5869 file in silcd/serverconfig.[ch]. It is used to tell whether we
5870 are the initiator to the remote router or whether we'll expect
5871 the other end to connect.
5873 * Moved registering of listener task to silc_server_init, hence
5874 the server starts listenning as soon as it is run, even if it
5875 does not have connections to other routers. Let's see how well
5878 * Changed default connection retry timeouts for more suitable in
5881 * Removed cipher and such arguments from silc_idlist_add_client
5882 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5883 Added new function silc_idlist_add_data to add the keys and stuff
5886 * Added SilcIDListData structure and added it to SilcClientEntry
5887 and SilcServerEntry as their first field in the structure. This
5888 way we can explicitly cast the ID entries to the SilcIDListData
5889 structure and get common data for the entries. In past, we had
5890 to first check what type of connection it is and then cast it to
5891 correct ID entry type. Now, we can directly cast the opaque
5892 pointer to the SilcIDListData (no matter what ID entry it actually
5893 is) and get the data needed.
5895 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5898 in some circumstances even if threre were timeout tasks, though not
5899 IO tasks, but tasks anyway. Now fixed.
5901 * Defined SilcServerConnection structure to hold connection specific
5902 stuff about directly connected servers and routers. The definition
5903 is currently in silcd/server_internal.h. I thought about having
5904 a bit more important role fro this struct but for now it is used
5905 only when connecting to other server (or router actually).
5907 * Added connecting retry support in server when connecting to
5908 router(s). The retry feature implement exponential backoff
5909 algorithm. Also, added SilcServerParams structure to hold default
5910 parameters for server. For now, it include these retry settings
5911 and are hard coded. After server is moded to be as Silc Server
5912 Library this structure will be more important.
5914 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Changed client librarys channel->clients table to SilcList and
5917 changed code accordingly.
5919 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Changed client's channel table to SilcList and changed code
5922 accordingly. Also changed SilcChannelClientEntry to include back-
5923 pointer to the channel so that client entry can use that structure
5924 as list as well and we have fast cross-reference to the channel.
5925 This change dramatically decreased the complexity of channel
5926 handling with client entry and vice versa (removed one extra
5927 loop when searching for channel entry from many functions).
5929 * Changed server->sim from table to SilcDList and changed code
5932 * NAMES command can now be used from user interface. It will show
5933 the user list on the channel, neatly.
5935 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5936 Code now saves realname of the user if it becomes available.
5938 * Renamed configure.in to configure.in.pre and made ./prepare
5939 script to automatically add correct version string to
5940 configure.in which it creates from configure.in.pre.
5942 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * NAMES command reply now shows users mode with the nickname when
5947 * Moved silc_client_ch[u]mode[_char] functions from
5948 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5949 place sucks, they are utility functions and should be in some
5952 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5954 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5957 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Added TRQ (efficient deque and list library) into lib/trq. This is
5962 a very good list library that is currently used in the SILC. Defined
5963 SilcList API over the library because I didn't like the API very
5964 much. See lib/trq/silclist.h for the API and examples of how to
5965 use the API. Fixed various places in the code to use the new
5966 SilcList API. The SilcList is meant for lists that has a structure
5967 already defined as a list. It is not suitable to add just some
5968 context to the list (in TRQ, the context is the list actually).
5970 So, I defined SilcDList that can be used for the purpose where
5971 predefined list structure does not exit. This can be used as
5972 such list. Now some context just can be added to the SilcDList.
5973 Currently this list is not used in the SILC just yet, though there
5974 are a lot places where this can replace dynamically allocated
5975 tables and I will fix these places, later, to use SilcDList.
5976 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5977 and use TRQ internally).
5979 Also fixed some annoying warning messages that the original TRQ
5980 code generated. Also minor changes to TRQ's Makefile.in.
5982 * Added support for querying by Client ID to both WHOIS and
5983 IDENTIFY commands into server, as required by the protocol.
5985 * Removed method function pointers from SilcBuffer structure. They
5986 weren't used to anything and just increased the context size for
5987 no good reason. This change also made silc_buffer_alloc and
5988 silc_buffer_free functions inline functions.
5990 * Disabled command flooding detection support until it's fixed so
5991 that it accepts commands in but does not execute them more than once
5994 * Added silc_net_localhost(), to return local hostname, into
5995 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5996 that must be initialized before calling silc_client_init.
5998 * Added new function: silc_server_send_notify_on_channels to send
5999 notify messages to all channels client has joined. It is assured
6000 that the message is sent only once per client.
6002 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6003 lib/silcutil/silcutil.[ch] as silc_format function. The new
6004 function is generic and is used by server as well, not only by
6005 the logging routines.
6007 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6008 the provided version string was not acceptable. Added new function:
6009 silc_ske_check_version into lib/silcske/silcske.h. The function
6010 must be implemented by the application (client or server) and it
6011 does not reside in the SKE library. The function checks the version
6012 string remote end sent.
6014 * Added back pointers (to opaque context and to SilcSocketConnection)
6015 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6017 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6018 duplicate packet context structure.
6020 * Changed `notify' client operation to send same arguments as client
6021 receives from server except for ID's. ID's are mapped to correct
6022 ID entry and that is returned. Also, if channel entry is not sent
6023 by server but the notify is for channel the channel entry is sent
6024 to application (otherwise application doesn't know that it is for
6025 channel (library gets it from packet's Destination ID)).
6027 * Added silc_client_remove_from_channels into client library to
6028 remove a client from all channels it has joined to. Used when
6029 received SIGNOFF notify from server. Added also new function
6030 silc_client_replace_from_channels to replace old ID entry with
6031 new ID entry on all channels. Used when received NICK_CHANGE
6034 * Fixed ID Cache list handling in silc_idlist_get_client in
6035 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6036 to get (or query) client by ID.
6038 * Updated TODO list.
6040 * Added connection authentication status message defined by the
6041 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6042 support for these into the code in client and server side.
6044 * Added generic function silc_client_send_command to send any command
6045 with variable argument list. Application should use this function
6046 to send commands if the command functions provided by the library
6047 does not suite for the application's user interface needs.
6049 * Added new `failure' client operation. Application is notified about
6050 received failure packet if client is executing a protocol. In this
6051 case the protocol's execution has failed.
6053 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6054 is required by the protocol.
6056 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6057 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6060 * Added status flag to SilcSKE object to indicate realtime status
6061 of the SKE protocol.
6063 * Application receives now exactly same command reply arguments as
6064 the library receives from server. However, if ID is received the
6065 corresponding ID entry is returned to the application (eg. Client
6066 ID is mapped to correct SilcClientEntry entry and that is returned).
6067 Changed command_reply client operation due to this change.
6069 * Changed all ID's in commands and in command replys as ID Payloads.
6070 Change affected both client and server side codes.
6072 All ID's sent in SILC network (with execption of ID's in SILC
6073 Packet header) are sent in ID Payload to support variable length
6076 * Server now notifies nick changes and notifies all clients on
6077 the channels about the new nickname (about the new Client ID,
6080 * Implemented CMODE command to change channel modes. Supports all
6081 channel modes defined by the protocol specs except ban and invite
6082 lists. (Also, private channel key mode is supported but support for
6083 setting private channel key in client is missing, thus, this mode
6084 has no effect on client side (except that server requires that the
6085 client uses private channel key and normal channel traffic does not
6088 Also, invite mode works per se, but INVITE command does not work
6089 yet correctly, so you can set channel as invite only channel but
6090 inviting clients to the channel does not work (it is yet to be
6091 thought what's the best way to do it).
6093 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6094 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6095 Implemented CUMODE command to change user's mode on the channel.
6096 Supports all modes defined by the protocol specs.
6098 * Added NAMES command reply to return users modes on the channel.
6100 * Removed unnecessary and slow ciphers from lib/silccrypt.
6102 * Set SO_KEEPALIVE option to connection sockets by default.
6104 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6106 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6107 redefined the Notify Payload into protocol specs.
6109 * Added silc_id_payload_parse_id to get ID directly from raw
6112 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6115 accept searching by Client ID as well.
6117 * Added support for LEAVE and SIGNOFF notify types in client library.
6119 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6120 to parse ID Payload from raw data.
6122 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Added flags parameter into silc_ske_assemble_security_properties
6125 function in lib/silcske/silcske.[ch].
6127 * Changed notify client operation to fit better for notify messages
6128 sent by server. The notify payload received from server is now
6129 passed to the application (after parsing it to SilcNotifyPayload).
6130 It is application's responsibility to retrieve the arguments
6131 from the payload and show the message the way it wants. The message
6132 sent by server is implementation specific.
6134 * Changed public keys to comply with the protocol specification.
6135 Old public keys are not supported anymore and are not compatible.
6137 * Removed nickname from Channel Payload as the latest draft removed
6138 it. The client must resolve the nickname from the NAMES command
6139 reply received when it joined the channel.
6141 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6143 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Fixed some errors in protocol specification drafts.
6147 * Created lib/silccore/silcnotify.c to implement Notify Payload
6148 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6149 generic payloads described by protocol specifications. The file
6150 includes implementations for ID Payload and Argument Payload.
6152 * Changed Command Payload implementation to use the new Argument
6153 Payload. Changed command_xxxx_payload to command_payload_xxxx
6154 to comply with SILC coding conventions.
6156 * Added suppport for Argument Payload handling in Notify Payload
6157 implementation as protocol requires it. Added the new support
6158 into server and client lib as well.
6160 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Added support for multiple nicknames on same channel. [n] is
6163 added locally to the nickname if there are more than one same
6164 nicknames on the channel.
6166 * Server now sends all nicknames that matched WHOIS request.
6167 Client also shows the list received from server.
6169 * Added TOPIC command to client side. User can now set and show
6170 current topic on channel.
6172 * Added MOTD command to client and server. Also, server sends the
6173 motd when client connects to the server.
6175 * Changed version strings to comply ISO 8601.
6177 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Fixed protocol error handling in client library. It should now
6180 cope even if the SKE fails for some reason.
6182 * Made new protocol specification drafts for submitting to IETF.
6184 * Implemented TOPIC command to server in silcd/command.c.
6186 * Added two new notify types into lib/silccore/silcnotify.h:
6187 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6188 notify nickname change and topic setting/change on a channel.
6190 * API change of command_reply operation in client library. The
6191 application gets now the status type received from server as well.
6193 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6197 * Cras fixed and optimized the packet handling even further and
6198 it should work now. Minor change to the prototype of function
6199 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6201 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added new function into lib/silcutil/silcschedule.[ch]:
6204 silc_schedule_with_fd to select() a specified fd. The function
6205 returns after timeout expires or data arrives or goes. The
6206 function is used by packet routines to wait that all data is
6207 received from network.
6209 * Fixed data reading from network in lib/silccore/silcpacket.c.
6210 The code now assures that all data is read from the fd and then
6211 continues packet processing. This was a bug fix since the code
6212 used to drop some data in some circumstances.
6214 * Added new function into lib/silcclient/client.[ch]:
6215 silc_client_start_key_exchange to start key exchange after
6216 connection has been established to server. The code internally
6217 now uses this funtion but its main purpose was to provide it
6218 for applications that perform their own connecting. After
6219 application has created a connection it merely calls this
6220 function to start the key exchange between client and server.
6221 The library takes care of everything else after that.
6223 Updated also lib/silcclient/README to explain the usage of
6226 * Do not send to application information that connection has
6227 been established. Application gets notified it by connect
6230 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Applied cras's patch to add silc_schedule_one function. The
6233 function runs scheduler once and returns.
6235 * Fixed the scheduler after cras messed it up. The timeout
6236 handling works now as it's supposed to work.
6238 * Added into lib/silccore/ silcnotify.h to include notify
6239 message types support. Changed silc_server_send_notify*
6240 functions, in server.[ch], to support those new notify types.
6241 Added the support for the notify types into client library,
6242 as well. Added new notify client operation into ops.h in
6245 * Changed silc_server_packet_send_to_channel to send normal
6246 packets instead of just channel message packets. The function
6247 is now used to send the notify packets to channels. It is not
6248 used to send channel message packets anymore, as server never
6251 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6252 va_arg()s as it seems to require it nowadays. I guess, if SILC
6253 is compiled with older va_arg() the new code should work anyway.
6255 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Splitted core library. Core library (lib/silccore) includes
6258 now only SILC protocol specific core (and common) components.
6259 Created new utility library (lib/silcutil) that includes more
6260 generic purpose stuff. The stuff for util library was taken
6261 from the old core library. This was minor and easy split.
6263 * Created SILC Client Library (lib/silcclient) that includes
6264 implementation of the SILC client without user interface. This
6265 was major move from silc/ directory. The code has been changed
6266 so that it is transparent towards the user interface. The
6267 silc/ directory includes now the same user interface as before
6268 and it uses the new client library. Read lib/silcclient/README.
6269 Basicly, the client library performs everything else related
6270 to SILC except user interface handling. Also, configuration
6271 files are considered to be part of user interface and library
6272 does not handle them.
6274 This change also changed a lot of structures, function naming etc.
6275 Most important change was that SilcClientWindow object was
6276 renamed to SilcClientConnection in the client library. Created
6277 also new file lib/silcclient/ops.h. Also added new files
6278 silc/local_command.[ch] and silc/client_ops.[ch].
6280 All these changes were made to make it easier for user interface
6281 designers to create what ever user interface for the SILC client
6284 It is also expected that the server will be moved to lib
6285 directory as well and SILC Server Library will be created;
6286 sometimes in the future.
6288 * Removed Local commands from lib/silccore/silccommand.h as
6289 they are application specific and new client library does not
6290 handle any of those anymore.
6292 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6293 old client implementation in silc/.
6295 * Added support for callback functions in SILC_LOG_* macros.
6296 Application can now set its own callbacks that will be called
6297 instead of using the default functions that will always print
6298 the debug messages to stderr (or stdout). Also, debugging can
6299 now be disabled by setting silc_debug to FALSE and re-enabled by
6300 setting it to TRUE. Note, that logging will still work even
6301 if debugging is disabled.
6303 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6304 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6305 silc_log_reset_debug_callbacks.
6307 * To enable debugging in silc client one must give now -d
6308 option on command line.
6310 * Changed silc_schedule_init to automatically allocate task queues
6311 if they are not allocated before calling it.
6313 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6315 * Added GMP 3.1 into math library.
6317 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6320 a channel in SILC network. The packet is used by servers and
6321 routers to notify other routers that user has left a channel.
6322 This little feature was missing until now. Added the feature
6323 to protocol specification as well.
6325 Added functions: silc_server_send_remove_channel_user and
6326 silc_server_remove_channel_user into server.[ch].
6328 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6329 lib/silccore/silcpacket.h. However, they are not implemented
6332 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Fixed joining to a channel and sending channel messages
6335 between server and router. The channel message sending should
6336 now work inside a cell.
6338 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Fixed the private message sending between server and router.
6341 The private message sending should now work inside a cell.
6343 * Added silc_server_replace_id into server.[ch] to replace
6344 existing ID in the SILC network.
6346 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6347 and silc_idlist_replace_server_id into idlist.[ch] in server.
6349 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Fixed the server to server connections. Server can again now
6352 connect to router. Router to router connections probably does
6355 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Added dynamic protocol registering support. Now protocols can
6358 registered and unregistered on the fly. Patch by cras.
6360 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Added lib/contrib directory to hold routines that some platforms
6363 don't have but are needed by SILC.
6365 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6366 into lin/contrib to provide getopt() and getopt_long() for
6367 those who don't have it.
6369 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Added AWAY command to client. When away message is set and
6372 client receives a private message packet the client automatically
6373 replies to the sender with the away message.
6375 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6376 bug seemed to be the cause of recent problems when compiling
6379 * Added version detection support to SKE protocol specification
6380 and added the new changes to the SKE implementation as well.
6381 There were other minor changes in the SKE protocol as well.
6383 Many changes in lib/silcske/silcske.[ch] and in
6384 lib/silcske/payload.[ch].
6386 * Added ^U functionality, clear input line. Patch from cras.
6388 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Mainly small bugfixes on core library. Fixed some debugging
6391 logging and buffer overflow in silclog.c.
6393 * Updated config.sub and config.guess on the distribution tree.
6395 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Added command lagging support in server. Client may execute
6398 commands now only once in two seconds.
6400 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Optimized packet reception. MAC computation and checking is now
6403 also more optimized. A lot previously duplicated code is now
6404 used as generic by both client and server.
6406 * Fixed key pair generation in clientutil.c
6408 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added into lib/silccore/silcbufutil.[ch] new function;
6411 silc_buffer_realloc.
6413 * Moved generic packet sending/encryption functions to
6414 lib/silccore/silcpacket.[ch] from client and server. Some
6415 rewriting of the functions.
6417 * Moved all generic packet reception/decryption functions to
6418 lib/silccore/silcpacket.[ch] from client and server. The
6419 packet processing is now much cleaner in both client and server.
6420 These were major changes in both client and server.
6422 * Created many common functions in server to do packet sending.
6423 Previously code were duplicated a lot, this has been removed
6426 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Rewrote major parts of the ID cache system. Don't know
6429 whether it is better now or not but at least the API is more
6432 * Major rewrite on ID cache stuff on client because of the ID
6433 cache API changes. Added idlist.c to client.
6435 * Also major rewrite on ID cache stuff on server as well.
6436 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6437 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6438 in hand, instead they are all put into the ID cache system now.
6439 All server_idlist_* routines uses ID cache now instead of
6440 traversing its own lists (those lists does not exist anymore).
6441 SilcIDList though still exists. Also, SilcXXXEntry's are
6444 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Finally made the SKE implementation compliant to the protocol
6447 specification. All mp integers are now binary encoded as
6448 opposed being HEX encoded.
6450 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6453 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6454 functions: silc_[encode/decode]_pem. Also added function
6455 silc_encode_pem_file to PEM encode with newlines ('\n') for
6458 * SILC public keys are now encoded either PEM or binary. Same
6459 option is for private keys as well. By default private keys
6460 are binary encoded and public keys PEM encoded. Silly HEX
6461 encoding were removed.
6463 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6464 function to create fingerprints.
6466 * Fixed a bug in SHA1; does not change the original data anymore.
6468 * Partly implemented INFO command on client and server side.
6469 Fixed CLEAR command. Changes to SERVER command; show current
6470 server(s) when giving command without arguments. Added
6471 VERSION command to client.
6473 * Added check to server that unregistered connections cannot
6474 execute commands (unless it is specificly allowed).
6476 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Fixed screen refresh.
6480 * Fixed channel joining bug from client. On some circumstances
6481 client tried to join to a channel it had already joined.
6483 * Added public key verification process into client's protocol.c.
6484 The client now verifies the public key from user and saves
6485 it into ~./silc/serverkeys/ directory.
6487 Added into: clientutil.[ch]: silc_client_verify_server_key.
6489 * Changed SKE protocol's silc_ske_initiator_finish function
6490 to accept callback function that verifies the received public
6491 key. Removed old silc_ske_verify_public_key function.
6493 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6496 silc_pkcs_private_key[_data]_set.
6498 * Made the password and public authentication more cleaner in
6499 server's protocol.c.
6501 * Removed historic and obsolete protocol `channel_auth' from
6502 both client and server.
6504 * Removed wrong way of sending command status messages from
6505 server to client in server's command.c. The old way violated
6506 protocol specification.
6508 Changes to silccore/silccommand.[ch]: removed
6509 silc_command_encode_status_payload -> not needed anymore,
6510 changed silc_command_encode_payload_va to accept extra
6511 argument on variable argument list. The argument type must
6512 now be provided to the function. Also, added new function:
6513 silc_command_encode_reply_payload_va which is same as
6514 normal command_encode_payload_va except command status type
6515 is provided as extra argument.
6517 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Added ~./silc directory handling. The directory includes the
6520 public and private keys for the client.
6522 Added silc_client_check_silc_dir, silc_client_create_identifier
6523 and silc_client_load_keys.
6525 * Implemented SILC protocol compliant public key. Added public
6526 and private key saving to and loading from files.
6528 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6529 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6530 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6531 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6532 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6534 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6535 silc_pkcs_load_[public/private]_key.
6537 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * Added silc_server_get_route (route.[ch]) to get connection
6540 data for the fastest route for given ID.
6542 * Implemented INVITE command on client and server. The command
6543 were re-defined in the SILC Protocol Specification and the
6544 implementation now complies with the specification.
6546 * Implemented PING command on client and server.
6548 * Implemented NAMES command on client and server. The server side
6549 supports currently only normal server not router server yet.

6552 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6554 * Implemented LEAVE command on client and server.
6556 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6557 again. This change was made to the protocol as well. Server
6558 should not violate the protocol specification anymore.
6560 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6562 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6563 was tested. SOCKS4 was not but should work anyway.
