1 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * The silc_packet_receive_process now returns FALSE if the
4 read data was invalid packet, and TRUE if it was ok.
6 The server now checks that if unauthenticated connection
7 sends data and its processing fails the server will close
8 the connection since it could be a malicious flooder.
10 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
12 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
14 * Make sure the warning about error opening a log file is
15 printed only once and not everytime it fails (produces
16 too much useless log). Affected file lib/silcutil/silclog.c.
18 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
20 * Fixed JOIN command parsing not to crash. Affected file
21 lib/silcclient/command.c.
23 * Fied the NICK_CHANGE notify to add the new client entry
24 even it is resolved. This removes an <[unknown]> nick
25 thingy bug in the client. Affected file is
26 lib/silcclient/client_notify.c.
28 * Do not try to allocate 0 bytes (efence does not like it)
29 in lib/silccore/silccomand.c when encoding payload.
31 * Do not take IRCNICK as nickname in Irssi SILC client since
32 it is not possible to set nickname before hand connecting
33 the server (TODO has an entry about adding auto-nicking
36 * Changed the silc_server_command_pending to check whether
37 there already exists an pending entry with the specified
38 command, command identifier and pending callback. This is
39 to fix IDENTIFY and WHOIS related crashes that may register
40 multiple pending commands with same identifier. Affected
43 * Fixed the server to reconnect to the router even if it
44 was already reconnecting and EOF was received. This to
45 fix a possibility that the server wouldn't ever try to
46 auto-reconnect to the router. Affected file silcd/server.c.
48 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
50 * Fixed the server's password authentication to use the
51 length of the locally saved password, and not the one
52 sent in the packet. Affected file silcd/protocol.c.
54 * Fixed same password authentication problem in the
55 Authentication Payload handling routines in
56 lib/silccore/silcauth.c.
58 * Yet another password authentication problem fixed with
59 channel password handling in silcd/command.c.
61 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
63 * If first character of string in silc_parse_userfqdn is '@'
64 then do not parse it. Affected file is
65 lib/silcutil/silcutil.c.
67 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
69 * Fixed minor bug in IDENTIFY command reply sending, which
70 caused various weird problems during JOIN when it was
71 resolving names for users. Affected file silcd/command.c.
73 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed the IDENTIFY command reply sending to chech better valid
76 clients. It was possible to send incomplete list of replies.
77 Affected file silcd/command.c.
79 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
81 * Added silc_client_command[s]_[un]register functions now to
82 dynamically register the commands in client library. Removed
83 the static table of commands. This allows the client library
84 to call commands without causing the application to know about
85 what commands library has called.
87 Removed the INFO command reply kludge to detect when the command
88 was called by library. Now library use its own command reply
89 function for INFO command.
91 Added function silc_client_command_call to call a command.
92 Application can use it to call command, not access the structure
95 Now all commands that are sent by the client library (not
96 explicitly sent by application) use own command reply functions.
98 Affected files around lib/silcclient/ and in
101 * Fixed the WHOIS command reply sending to chech better valid
102 clients. It was possible to send incomplete list of replies.
104 Fixed the WHOIS and IDENTIFY to send the request to router
105 if normal server did not do it and did not find any results.
107 Affected file silcd/command.c.
109 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
111 * Moved the internal data from SilcClient context into its
112 own file, not accesible to application. Affected files
113 lib/silcclient/client.h and lib/silcclient/client_internal.h,
114 and other files in client library.
116 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Added doc/examples installation target in Makefile.am.pre.
121 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
123 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
124 commands the found client entry will be removed from the
125 cache, after notifying application about the error. Affected
126 file lib/silcclient/command_reply.c.
128 * Changed the /MSG to check for exact nickname user gave, and
129 not let `nick' match `nick@host' if it is only one found. Now,
130 user must type the exact nickname (like nick@host2) even if
131 there are no more than one same nicks found. This is to avoid
132 a possibility of sending nickname to wrong nickname since
133 `nick' could match `nick@host'. Affected file is
134 irssi/src/core/silc-servers.c.
136 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
138 * Do not print "you are now server operator" or similar when
139 giving /away command. Affected files are
140 irssi/src/silc/core/client_ops.c, silc-servers.h.
142 * Made the silc_server_command_pending_error_check to send
143 the same command reply payload it received back to the
144 original sender of the command. This way all arguments
145 that was received by the server will be received by the
146 client too. Affected file silcd/command.c.
148 * Added the silc_idcache_add to return the created cache entry
149 to a pointer. Affected file lib/silccore/silcidcache.[ch].
151 * Add global clients to expire if they are not on any channel.
152 This is because normal server will never know if they signoff
153 if they are not on any channel. The cache expiry will take
154 case of these entries. This is done by normal servers only.
155 The affected files are silcd/command_reply.c,
156 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
158 * If server receives invalid ID notification for WHOIS or
159 IDENTIFY and the ID exists in the lists, it is removed.
160 Affected file silcd/command_reply.c.
162 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
163 in client then client entry that it matches is searched and
164 the nickname is printed on the screen for user. Affected
165 file irssi/src/silc/core/client_ops.c.
167 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
169 * Use cache entry expire time in the LIST command reply to
170 purge old entries from the cache after the LIST command
171 reply has been received. This way we don't have non-existent
172 entries in the cache for too long. Affected file is
173 silcd/command_reply.c.
175 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
177 * If we are normal server, and we've not resolved client info
178 in WHOIS or IDENTIFY from router, and it is global client,
179 we'll check whether it is on some channel. If it is not
180 then we cannot be sure about its validity and will resolve it
181 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
182 file silcd/command.c.
184 * Search channel by name (if possible) rather than by ID
185 in IDENTIFY command's command reply. Affected file is
186 silcd/command_reply.c.
188 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Distribute to the channel passphrase in CMODE_CHANGE notify.
191 Updated specs and implemented it. Affected file silcd/command.c,
192 silcd/packet_send.c and silcd/packet_receive.c.
194 * Implemented the <founder auth> payload handling in the JOIN
195 command. If provided all conditions for channel joining
196 except requirement to provide correct passphrase can be
197 overrided by the channel founder. Updated the protocol specs.
198 Affected file silcd/command.c.
200 Added support for founder auth in JOIN command in client
201 library. Fixed the parsing of the JOIN command now to support
202 all options as they should be. The affected file is
203 lib/silcclient/command.c.
205 * Optimized the WHOIS and IDENTIFY commands to send the request
206 to router only if it includes nicknames or other names. If
207 they include only IDs then check the local cache first before
208 routing. Affected file is silcd/command.c.
210 * Added channels topic announcements. Affected file is
211 silcd/packet_receive.c and silcd/server.c.
213 * Fixed the silc_server_send_notify_topic_set to really destine
214 the packet to channel. Affected file silcd/packet_send.c.
216 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
217 library. Affected file lib/silcclient/client_notify.c.
219 * Added UMODE announcements. Affected file silcd/server.c.
221 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
223 * Memory leak fixes in:
225 lib/silcutil/silcsockconn.c
226 lib/silcske/silcske.c
229 lib/silccrypt/silcpkcs.c
230 lib/silccore/silccommand.c
231 lib/silccore/silcidcache.c
236 * ROBOdoc documented the lib/silcske/groups.h file and a
237 bit changed the interface for better.
239 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
241 * Update the client entry context in the ID cache after
242 nick change. Affected file lib/silcclient/command.c.
243 Fixes the CUMODE command when regaining founder privileges,
244 and a little WHOIS problem.
246 * Fixed silc_net_gethostbyname to correctly call the
247 inet_ntop. Affected file lib/silcutil/silcnet.c.
249 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
251 * Added IPv6 support checking to the configure.in.pre, added
252 also --enable-ipv6 option to override the check. Affected
253 file configure.in.pre.
255 * The silc_thread_create now calls the start function
256 directly if threads support is not compiled in. Removes
257 ugly #ifdef's from generic code. Affected files are
258 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
260 * Added silc_net_gethostby[name/addr]_async to asynchronously
261 resolve. Affected files are lib/silcutil/silcnet.[ch].
263 * Added support for rendering IPv6 based server, client and
264 channel IDs. Affected file lib/silcutil/silcutil.c.
266 * Added support for creating IPv6 based server IDs. Affected
267 file is silcd/serverid.c.
269 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
271 * Added silc_net_gethostby[addr/name] into the
272 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
273 routines. Added silc_net_is_ip[4/6]. Affected file is
274 lib/silcutil/unix/silcunixnet.c. All routines that take
275 address as argument now supports both IPv4 and IPv6 addresses.
277 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
279 * Fixed LIST command reply sending in server. Affected file
282 * Server now sends the kicker's client ID in the KICK notify
283 to the kicked client. Affected file silcd/command.c.
285 * The client library now parses the kickers client ID and
286 UI displays it. Affected files lib/silcclient/client_notify.c
287 and irssi/src/silc/core/silc-channels.c, module-formats.c.
289 * Made all payload parsing function prototypes consistent.
290 They all take now const unsigned char * and uint32 pair as
291 the payload data instead of SilcBuffer. Changes all around
292 the source tree. Other unsigned char* -> const unsigned char*
293 changes around the tree as well.
295 * Optimized SFTP client and server packet sending not to
296 allocate new buffer for each packet but to recycle the
297 first allocated buffer. Affected files are
298 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
300 * Optimized the SFTP client to use SilcList instead of
301 SilcDList for requests, because it is faster. Affected file
302 is lib/silcsftp/sftp_client.c.
304 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
305 into lib/silccore/silcid.[ch].
307 Renamed silcpayload.[ch] into silcargument.[ch].
309 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
311 * If client entry is deleted with active key agreement
312 session, abort the session.
314 The silc_client_abort_key_agreement now calls the completion
315 callback with new SILC_KEY_AGREEMENT_ABORTED status.
317 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
320 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
322 * Don't use __restrict in older GCC's. Affected file is
323 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
325 * silc_net_localhost now attempts to reverse lookup the
326 IP/hostname. Affected file lib/silcutil/silcnet.c.
328 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
329 command. It can be used to gain founder privileges at
330 the same time when joining the channel.
332 Defined that the SILC_NOTIFY_TYPE_KICKED send the
333 kicker's client ID as well. Updated protocol specs.
335 Defined that the server must send SILC_COMMAND_IDENTIFY
336 command reply with error status to client who sent
337 private message with invalid client ID.
339 Updated the protocol specification.
341 * Added silc_server_send_command_reply to send any
342 command reply. Affected file silcd/packet_send.[ch].
344 * Added silc_id_payload_encode_data to encode ID payload
345 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
347 * The server now send IDENTIFY command reply with error
348 status if client ID in private message is invalid. Affected
349 file silcd/packet_receive.c.
351 * Save the server key file with server's IP address in
352 the filename instead of hostname. The affected file is
353 irssi/src/silc/core/client_ops.c.
355 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
357 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
360 * Added libtool support for compiling shared objects in
361 lib/silcsim. Affected file configure.in.pre and
362 lib/silcsim/Makefile.am. Original patch by cras.
364 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Pid file configuration, and server's config file fixes
367 patch by toma. Updated CREDITS file.
369 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Fixed silc_client_channel_message to not try to decrypt
372 the message twice if it resolved the destination client
373 information. This could cause of dropping one channel
374 message. Affected file lib/silcclient/client_channel.c.
376 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Added silc_client_run_one into lib/silcclient/silcapi.h and
379 lib/silcclient/client.c. This function is used when the SILC
380 Client is run under some other scheduler, or event loop or
381 main loop. On GUI applications, for example this may be
382 desired to used to run the client under the GUI application's
383 main loop. Typically the GUI application would register an
384 idle task that calls this function multiple times in a second
385 to quickly process the SILC specific data.
387 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
389 * Fixed silc_server_drop() for dropping the supplementary
390 groups as well, this could cause a security hole on some
393 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
395 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
398 * Write PID file after dropping privileges. Added -F option
399 to run server on foreground. A patch by debolaz.
400 Affected files silcd/server.c, silcd/silcd.c.
402 * Fixed MOTD to return the MOTD file server name. Affected
403 file silcd/command.c.
405 * Added INFO command reply handling to the Irssi SILC Client.
406 Affected file irssi/src/silc/core/client_ops.c.
408 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
410 * Fixed the silc_idcache_list_* routines to really support
411 the dynamic list. Fixes a crash. Affected file is
412 lib/silccore/silcidcache.c.
414 * Fixed the LIST command reply to really call LIST command's
415 pending callbacks. Affected file silcd/command_reply.c.
417 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Update conn->local_entry->nickname after giving NICK
420 command. Affected file lib/silcclient/command.c.
422 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
424 * Added the [pid] option to the silcd configuration file
426 Affected files: serverconfig.[ch] and silcd.c
428 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
430 * Save fingerprint in WHOIS command reply in server.
431 Affected file silcd/command_reply.c.
433 * Fixed NICK commands pending callback registration.
434 Affected file lib/silcclient/command.c.
436 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
438 * Use ++server->cmd_ident when sending commands in server,
439 instead of random number. Affected file silcd/command.c.
441 * Fixed GETKEY command reply to call actually GETKEY pending
442 command callbacks. Affected file silcd/command_reply.c.
444 * A bit stricter check for nicknames. Check for same nickname
445 in NICK command also. Affected file silcd/command.c.
447 * Do not call INFO command everytime client ID changes, only
448 during first connecting. Affected file lib/silcclient/client.c.
450 * Set the new nickname only after successful command reply for
451 NICK command is returned by server. Affected file
452 lib/silcclient/command.c.
454 * Remove nicknames from nicklist during server_signoff notify.
455 Should fix /NAMES bit more. The affected file is
456 irssi/src/silc/core/silc-channels.c.
458 * Added `fingerprint' field to the SilcIDListData in the
459 silcd/idlist.h to hold the fingerprint of the client's
462 Send the fingerprint of the client's public key in WHOIS
465 Affected files silcd/command.c, and silcd/idlist.[ch].
467 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
468 create fingerprint from given data.
470 * Show the fingerprint of the client's public key in WHOIS.
471 Affected files irssi/src/module-formats.[ch] and
472 irssi/src/silc/core/client_ops.c.
474 * Format the multiple same nicknames also during JOIN and
475 NICK_CHANGE notifys. Affected file is
476 lib/silcclient/client_notify.c.
478 * Do not print error on screen for invalid private message
479 payload since it can come if someone is sending private
480 messages with wrong key. Affected file
481 lib/silccore/silcprivate.c.
483 * Fixed multiple concurrent /PING crash. Affected file
484 lib/silcclient/command.c.
486 * Changed the wrong ID encoding. All IP addresses must be
487 in MSB first order in encoded format. They were encoded
488 wrong and was in LSB format. Affected files are
489 silcd/serverid.c, lib/silcutil/silcutil.c.
491 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
493 * Call the `connect' client operation through the scheduler
494 in case of error. Affected file lib/silcclient/client.c.
496 * Call the `failure' client operation even if the error
497 occurred locally during a protocol. Affected file is
498 lib/silcclient/protocol.c.
500 * Added support of sending LIST command to router from normal
501 server. This way normal server can get list of all channels
502 in the network too. Fixed the channel list sending in the
503 server too. Affected files are silcd/command.c, and
504 silcd/command_reply.[ch].
506 * Added silc_server_update_channels_by_server and
507 silc_server_remove_channels_by_server. They are used during
508 disconnection of primary router and in backup router protocol.
509 Affected file silcd/server_util.[ch], silcd/server.c and
510 silcd/server_backup.c.
512 * Fixed channel adding to global list in IDENTIFY command
513 reply in server. Affected file silcd/command_reply.c.
515 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
517 * If the incoming packet type is REKEY or REKEY_DONE process
518 that packet always synchronously. Fixes yet another MAC
519 failed error on slow (dialup) connections. Affected file
520 lib/silcclient/client.c and silcd/server.c.
522 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
524 * Call check_version SKE callback for initiator too. Affected
525 file lib/silcske/silcske.c.
527 * Implemented fix for security hole found in the SKE that was
528 fixed in the specification few days back; the initiator's
529 public key is now added to the HASH value computation.
530 Added backwards support for the old way of doing it too, for
531 old clients and old servers. Affected file is
532 lib/silcske/silcske.c.
534 * Enabled mutual authentication by default in SKE. If initiator
535 is not providing mutual authentication the responder will
536 force it. This will provide the proof of posession of the
537 private key for responder. The affected files are
538 lib/silcclient/protocol.c and silcd/protocol.c.
540 * Do not cache anymore the server's public key during SKE.
541 We do mutual authentication so the proof of posession of
542 private key is done, and if the server is authenticated in
543 conn auth protocol with public key we must have the public
544 key already. Affected file silcd/protocol.c.
546 * Added new global debug variable: silc_debug_hexdump. If
547 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
548 file lib/silcutil/silclog.[ch].
550 * Fixed compilation warning due to char * -> const char *.
551 Affected files lib/silcutil/silcnet.h, and
552 lib/silccore/silcauth.[ch].
554 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Fixed CMODE command when new channel key was created. If
557 the creation failed the old key was removed. Next time giving
558 same command would crash the server since the old key was
559 freed already. Affected file silcd/command.c.
561 * Fixed the silc_server_announce_get_channels to not crash
562 on reconnect. Affected file silcd/server.c.
564 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Added silc_log_set_debug_string function to set a regex
567 string to match for debug output. Only the function names,
568 or filenames matching the given debug string is actually
569 printed. This way it is possible to filter out those debug
570 strings that user is not interested in.
572 Fixed a bug in silc_string_regexify.
574 Affected files lib/silcutil/silclog.[ch], and
575 lib/silcutil/unix/silcunixutil.c.
577 * Changed the -d options in both server and Irssi SILC client
578 to take the debug string as argument. Affected files
579 silcd/silcd.c and irssi/src/silc/core/silc-core.c.

583 * Added silc_hash_babbleprint to create a Bubble Babble
584 Encoded fingerprint. The encoding is developed by Antti
585 Huima (draft-huima-babble-01.txt), and it creates human
586 readable strings out of binary data. Affected file
587 lib/silccrypt/silchash.[ch].
589 * Print the babble print now in addition of fingerprint as well
590 in Irssi SILC client. Affected files are
591 irssi/src/fe-common/silc/module-formats.[ch],
592 irssi/src/fe-common/silc/core/client_ops.c.
594 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
596 * Fixed a security problem found in SKE. The initiator's
597 public key too is now added to the HASH hash value creation
598 which is signed by the responder to create the SIGN value.
599 This will prevent anyone in the middle to lie to the responder
600 about the initiator's public key. If this is done now, the
601 man in the middle will get caught. Updated the protocol
604 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Better installation directory handling. Configure module
607 paths and other paths automatically to example_silc* files
608 in doc/. A patch by toma.
610 * Fixed compiler warning from MPI library, and from SILC RNG.
613 * Added SILC_SERVER_PID_FILE to define the pid file for server.
614 It can be configured with ./configure. A patch by toma.
616 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
618 * Find correct make to use in prepare-clean. A patch by
619 toma. Affected file prepare-clean.

640 * Added silc_pkcs_public_key_compare to compare two
641 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
643 * Check that the client who set the founder mode on the
644 channel is the same client that is giving the founder
645 mode to itself. It is done by comparing the saved public
646 key (it is saved even in the authentication is passphrase).
647 Affected file silcd/command.c.
649 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
651 * Do not process packet for disconnected socket connection.
652 Affected file lib/silccore/silcpacket.c.
654 * Process the DISCONNECT packet through scheduler in the
655 client library. Affected file lib/silcclient/client.c.
657 * Fixed the silc_client_packet_parse to not to increase
658 the packet sequence number if the conn->sock and the
659 current socket connection is not same. This can happen
660 for example during key agreement when the conn includes
661 multiple socket connections (listeners). Affected file
662 lib/silcclient/client.c.
664 * The sender of the file transfer request now provides also
665 the pointer (listener) for the key exchange protocol. If
666 the listener cannot be created then it sends empty key
667 agreement and lets the receiver provide the listener.
669 Added `local_ip' and `local_port' arguments to the
670 silc_client_file_send. If they are provided they are used,
671 if not then it will attempt to find local IP address, if
672 not found or bind fails then the remote client will provide
675 Affected files are lib/silcclient/client_ftp.c and
676 lib/silcclient/silcapi.h.
678 * Extended the FILE SEND command to support defining the
679 local IP and port for key exchange listener. They are

684 * Defined to WHOIS command reply the sending of fingerprint
685 of the client's public key (if the proof of posession of the
686 corresponding private key is verified by the server).
687 Updated to the protocol specification.
689 * Added support of receiving the client's public key's
690 fingerprint in command reply in client library. Affected
691 file is lib/silcclient/command_reply.c, and
692 lib/silcclient/idlist.[ch].
694 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

708 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
710 * Send error message to application if opening file for
711 writing during file transfer fails. Affected file is
712 lib/silcclient/client_ftp.c.
714 Remove all file transfer sessions for a client that we're
715 removing from ID cache.
717 Affected file is lib/silcclient/client_ftp.c.

747 client library. Affected file lib/silcclient/client_prvmsg.c.
749 * Do not actually remove the client directly from ID cache
750 during SERVER_SIGNOFF, but invalidate it. This way we
751 preserve the WHOWAS info for the client. Affected file
754 * Fixed SERVER_SIGNOFF notify handling in the server. The
755 server is now able to process incoming SERVER_SIGNOFF notify
756 for a server that it doesn't even know about. It will remove
757 the clients provided in the notify. Affected file
758 silcd/packet_receive.c.
760 * Check for partial packet in data queue after every packet that
761 was found from the queue. Return and wait for more data if
762 there is partial data in queue. Affected file is
763 lib/silccore/silcpacket.c.
765 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

780 irssi/src/fe-common/silc/module-formats.[ch].
782 * Wrote a help file for FILE command.
784 * Added silc_rng_global_get_byte_fast to get not-so-secure
785 random data as fast as possible. Random data is read from
786 /dev/urandom if available and from the SILC RNG if not
787 available. It is used in padding generation. Affected file
788 lib/silccrypt/silcrng.[ch].
790 * All packets in client library are now processed synchronously.
791 Optimized packet processing a lot. Affected file
792 lib/silcclient/client.c.
794 * All server connection packets are processing synchronously
795 now in server, to optimize packet processing. Affected file
798 * Include files are installed now only in Toolkit distribution
799 if make install is given. Affected files: all Makefile.am's.
801 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
803 * Assure that silc_client_notify_by_server_resolve does not
804 resolve the client information multiple times. If it cannot
805 be found by the first it cannot be found at all. Affected
806 file lib/silcclient/client_notify.c.
808 * Fixed WHOWAS command reply calling. Affected file
809 lib/silcclient/command_reply.c.
811 * Removed all references to silc_idlist_get_client from the
812 Irssi SILC client since that call is internal call used by
813 the library. The Irssi SILC client will use now client
814 retrieval functions found in silcapi.h.
816 * Fixed a bug in resolving nickname info before sending
817 private message. It used freed memory. Affected file
818 irssi/src/silc/core/silc-servers.c.
820 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

839 * Added silc_net_localip to return local host's IP address.
840 Affected file lib/silcutil/silcnet.[ch].
842 * If key exchange or rekey protocol is active for a connection
843 parse all packets syncronously since there might be packets
844 in packet queue that we are not able to process without first
845 processing packets before them. Affected file silcd/server,
846 lib/silcclient/client.c.
848 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
849 whether library should continue processing the packet.
850 Affected file lib/silccore/silcpacket.h.

896 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
897 is incomplete and is being resolved, it won't be resolved
900 Make sure also that USERS command reply does not resolve
901 twice information. Affected file is
902 lib/silcclient/command_reply.c.
904 Make sure that silc_client_get_clients_by_list does not
905 resolve twice same information.
907 * Check for valid client->id in the silc_server_free_client_data.

933 * Redefined the SILC packet header to include the padding
934 length. Affected file lib/silccore/silcpacket.[ch].
936 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
937 length for maximum padding up to 128 bytes). Affected
938 file lib/silccore/silcpacket.h.
940 * Removed all backwards support for old 0.5.x MAC thingies.
941 The SILC packet header change makes it impossible to be
942 backwards compatible.
944 * Send the ENDING packet with timeout in the backup resuming
945 protocol. This is to assure that all routers has connected
946 to the primary router. Affected file silcd/server_backup.c.
948 * Changed the RNG to take the first IV from random data. It
949 used to take it from zero actually. Changed the RNG also
950 to use /dev/urandom during session. /dev/random is used
951 in initialization. Affected file lib/silccrypt/silcrng.[ch].
953 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Changed the SILC packet header to have the first two bytes
956 (the packet length) encrypted. Affected files aroung the
957 code tree, lib/silccore/silcpacket.[ch]. Removed the
958 SilcPacketCheckDecrypt callback. It is not needed anymore
959 since the silc_packet_receive_process will determine now
960 whether the packet is normal or special.
962 * Implemented the unidirectional MAC keys. Affected files
963 lib/silcske/silcske.c, silcd/protocol.c and
964 lib/silcclient/protocol.c.

971 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Allow backup router to announce servers. All servers
974 announced by backup router are added to the global list
975 automatically. Update hte server's socket to our primary
976 router also when backup router announces a server.
977 Affected file silcd/packet_receive.c.
979 * Do not update the client->router in the function
980 silc_server_udpate_clients_by_server if the client is on
981 global list. We might fail to find any specific server
982 for locally connected clients and local cell clients. They
983 should still use the `from' and not `to' as client->router.
984 This fixes backup router resuming protocol. Affected file
987 * Decrease channel statistics count only if the channel
988 deletion worked. Affected files are silcd/server.c and
991 * Added silc_server_update_servers_by_server to update origin
992 of all server entries. Used during backup router protocol.
993 Affected files silcd/server_util.[ch], silcd/server.c. and

1006 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Made better checks that the channel message is not sent
1009 to the router it came from. Affected file is
1010 silcd/packet_send.c. Fixed memory leak too.
1012 * Announce informations for incoming router connection, but
1013 only after checking if it is replaced by backup router.
1014 Affected file silcd/packet_receive.c.
1016 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1019 router environment. Affected file silcd/server_backup.c.
1021 * Route packet only to one router in the function
1022 silc_server_packet_send_to_channel. Affected file is
1023 silcd/packet_send.c.
1025 * Fixed silc_server_send_notify_dest to set the broadcast
1026 flag. Fixed the silc_server_send_notify_topic to actually
1027 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1028 Affected file silcd/packet_send.c.
1030 * Changed the SFTP Filesystem interface. Changed the
1031 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1032 the filesystem operation function. The SilcSFTPFilesystem
1033 is now a context that is allocated by all filesystem allocation
1034 functions and it already includes the operations structure
1035 and filesystem specific context. It is given as argument
1036 now to the silc_sftp_server_start. This made the interface
1037 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1038 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1040 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Changed the backup router adding and getting interfaces
1043 in the server. The router that will be replaced by the
1044 specified backup router is now sent as argument. Affected
1045 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1048 * Added silc_net_addr2bin_ne to return the binary form of
1049 the IP address in network byte order. Affected files

1105 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1106 in the server to indicate disabled entry. All data read
1107 from the connection will be ignored and no data is sent
1108 for entry that is disabled. Affected files are
1109 silcd/idlist.h, silcd/server.c.
1111 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Created SFTP client and server test programs in the
1114 lib/silcsftp/tests directory.
1116 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Implemented memory filesystem (virtual filesystem) for
1119 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1122 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1124 * Implemented the SFTP (SSH File Transfer Protocol) to the
1125 lib/silcsftp. It includes SFTP client and SFTP server
1128 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Moved lib/silccore/silcprotocol.[ch] to the
1131 lib/silcutil library.
1133 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1134 take variable argument list pointer as argument. Affected
1135 file lib/silcutil/silcbuffmt.[ch].
1137 * Added silc_buffer_set function that is used to set data
1138 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1139 Affected file lib/silcutil/silcbuffer.h.
1141 * Changed various routines in the core library to use the new
1142 silc_buffer_set instead of allocating new buffer only for
1145 * Added 64-bit value formatting and unformatting support to the
1146 silc_buffer_[un]format routines. Affected file is
1147 lib/silcutil/silcbuffmt.[ch].
1149 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1150 to includes/bitmove.h.
1152 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1154 * Fixed channel user mode saving in client library. Affected
1155 file lib/silcclient/command[_reply].c.
1157 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1159 * Defined the file transfer to the SILC Protocol. Added
1160 new packet type SILC_PACKET_FTP and defined File Transfer
1161 Payload. The mandatory file transfer protocol is SFTP
1162 (SSH File Transfer Protocol). Affected file in addition
1163 of the internet draft is lib/silccore/silcpacket.h.
1165 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1166 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1167 is used as part of backup router protocol when the primary
1168 router of the cell is back online and wishes to resume
1169 the position as primary router.
1171 * Redefined the MAC generation keys in the protocol. The
1172 same key is not used anymore in both direction. Both
1173 direction will now use different keys for sending and
1174 receiving. This fixes a potential security flaw. This
1175 change causes incompatibilities in the protocol.
1177 * Redefined also the MAC computation from the packet.
1178 An packet sequence number is now added to the MAC
1179 computation. This prevents possible replay attacks against
1180 the protocol. This change too causes incompatibilities
1183 Added `sequence' field to the SilcPacketContext to hold
1184 the current sequence number for the packet.
1186 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Added `created' field to the SilcIDListData in the file
1189 silcd/idlist.h to indicate the time when the entry was
1192 * Added `created' field to the SilcChannelEntry too. Affected
1193 file silcd/idlist.h.
1195 * Added `creation_time' aguments to all the announcement functions
1196 in the server. If it is provided then only the entries that
1197 was created after the provided time frame are actually
1198 announced. Affected file silcd/server.[ch].
1200 * The protocol says that the Channel ID's IP address must be
1201 based on the router's IP address. Added check for this in
1202 the silc_server_new_channel when processing incoming New Channel
1203 Payload. Affected file silcd/packet_receive.c.
1205 * Print out the correct version with --version in SILC client.
1206 Affected file irssi/src/silc/core/silc-core.c.
1208 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Fixed WHOWAS command to check for completnes of the client
1211 entry always, not just when the command is coming from client.
1212 Affected file silcd/command.c.
1214 * Added new function silc_server_packet_queue_purge to purge the
1215 outgoing data queue to the network. After the function returns
1216 it is guaranteed that the outgoing packet queue is empty.
1217 Affected file silcd/packet_send.[ch].
1219 * Purge the outgoing packet queue in the rekey protocol's final
1220 callback to assure that all rekey packets go to the network
1221 before quitting the protocol. Affected file silcd/server.c.
1223 * Added silc_client_packet_queue_parse as similar function as
1224 in server to the client library. The affected file is
1225 lib/silcclient/client.c.
1227 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Splitted silcd/server.c and created silcd/server_util.[ch]
1230 for utility functions.
1232 * Added new socket flag SILC_SF_DISABLED to indicate that the
1233 connection is open but nothing can be sent to or received from
1234 the connection. Affected file lib/silcutil/silsockconn.[ch].
1235 The checking for disabled socket is checked in the low level
1236 silc_socket_write and silc_socket_read functions.
1238 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Allow only nicknames and channel names that fits into the
1241 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1243 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * When processing JOIN command reply in server check that if
1246 the channel exists in our global list we'll move it the local
1247 list. Affected file silcd/command_reply.c.
1249 * Fixed the check whether client is joined on the channel already
1250 in JOIN command. Affected file lib/silcclient/command.c.
1252 * Fixed the JOIN command reply to check whether the channel
1253 already exists. Affected file lib/silcclient/command_reply.c.
1255 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Added silc_ske_status_string to map the SKE error numbers
1258 to readable strings. The affected files are
1259 lib/silcske/silcske[_status].[ch].
1261 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Do not show the private channels on the WHOIS channel list
1264 as it is not allowed by the protocol. The affected file is
1267 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Assure that the packet length digged from the actual packet
1270 is something sensible in the silc_packet_decrypt_rest_special
1271 in lib/silccrypt/silcpacket.c.
1273 * Free and NULL the allocated pointer in silc_hmac_alloc if
1274 the HMAC allocation fails. The affected file is
1275 lib/silccrypt/silchmac.c.
1277 * Print the selected security properties to the log files in
1278 the server. Affected file silcd/protocol.c.
1280 * Add SKE's reference counter even if calling the completion
1281 callback manually. Otherwise it goes negative, although it
1282 does not cause any problems. The affected file is
1283 lib/silcske/silcske.c.
1285 * Remove the client entry with short timeout after giving the
1286 KILL command. Affected file lib/silcclient/command.c.
1288 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1289 case all found clients are already disconnected (WHOWAS would
1290 found them) in the server. Affected file silcd/command.c.
1292 * Update the last_receive (time of last data received) to be
1293 updated only when received private or channel message so that
1294 the idle time showed in WHOIS makes more sense.
1296 * Added boolean field `valid' in to the SilcClientEntry in the
1297 client library to indicate whether the entry is valid or not.
1298 This fixes the nickname change bug on channel when changing
1299 the nickname to be same than the old (like nick to Nick) the
1300 nickname formatter doesn't set the new nick anymore to Nick@host.
1301 Affected file lib/silcclient/idlist.[ch].
1303 * Now actually fixed the nickname changing on disconnection.
1304 Added new function silc_change_nick to the Irssi SILC Client.
1305 Affected file irssi/src/silc/core/client_ops.c,
1306 irssi/src/silc/core/silc-nicklist.[ch].
1308 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Check that the public key exists in the GETKEY command before
1311 trying to encode it. Affected file silcd/command.c.
1313 * Print some notifications on received public keys with GETKEY
1314 command in the Irssi SILC Client. Affected files are
1315 irssi/src/fe-common/silc/module-formats.[ch],
1316 irssi/src/silc/core/client_ops.c.
1318 * Use IDENTIFY command to resolve the server information in the
1319 GETKEY command instead of INFO command. Affected file
1320 lib/silcclient/command.c.
1322 * All command reply functions in the client library now calls
1323 the pending command reply callbacks even if an error has
1324 occurred. The server has done this a long time and now it was
1325 time to move the client library to this as well. Now all
1326 errors can be delivered back to the pending command reply
1327 callbacks if necessary. Affected files are
1328 lib/silcclient/command[_reply].[ch].
1330 * Change the nickname on disconnection back to the username
1331 because in reconnect the server will enforce it to it anyway.
1332 Affected file irssi/src/silc/core/silc-servers.c.
1334 * Fixed a config file parsing bug in the Irssi SILC client.
1335 Affected file irssi/src/silc/core/clientconfig.c.
1337 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * When printing the channel mode on JOIN, verify that the
1340 channel key and channel's HMAC are valid. Affected file
1341 irssi/src/silc/core/client_ops.c.
1343 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1346 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1347 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1349 * Removed channel key rekey task deleting from the function
1350 silc_server_save_channel_key. Affected file silcd/server.c.
1351 Added explicit timeout task context instead that is used to
1352 delete the task if we are registering a new task before the
1353 new task has elapsed.
1355 * When channel key rekey occurs the client library now saves
1356 the old channel key for a short period of time (10 seconds) and
1357 is able to use it in case some is still sending channel
1358 messages encrypted with the old key after the rekey. Affected
1359 file lib/silcclient/[idlist.h|client_channel.c].
1361 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Added check to the silc_server_new_id_real to not accept
1364 new ID if it is the sender's own ID. Affected file is
1365 silcd/packet_receive.c.
1367 * Assure that we do not announce ourself or the one we've
1368 sending our announcements when we're router and are announcing
1369 servers to our primary router. Affected file silcd/server.c.
1371 * Fixed silc_server_command_identify_check_client to assemble
1372 correct WHOIS packet. It send corrupted WHOIS packet and
1373 caused problem with router to router connections. Affected
1374 file silcd/command.c.
1376 Fixed also silc_server_command_whois_check the same way
1377 as for the IDENTIFY command.
1379 * Added new SilcIDListStatus to the server in the SilcIDListData
1380 structure. The status now includes the current status of
1381 the entry (like registered, resolved etc.). Affected file
1382 silcd/idlist.[ch]. Defined a bunch of different status types
1383 as well. This replaced the old boolean registered field as well.
1385 Added resolve_cmd_ident field to the SilcClientEntry structure
1386 too so that if the entry is for example being resolved so
1387 another command may attach to the same pending command reply
1388 without requiring to resolve the same entry again. This concept
1389 should optimize the WHOIS and the IDENTIFY resolving under
1390 heavy load by taking away unnecessary resolving for entries
1391 that are being resolved already.
1393 Added support for adding multiple pending commands for one
1394 command idenfier. Affected file silcd/command[_reply].[ch].
1396 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1397 before deleting the data. Otherwise the hash table will have
1398 freed data in comparison functions. Affected file is
1399 silcd/command_reply.c.
1401 * Fixed silc_idlist_replace_client_id to add the new entry to
1402 the cache with NULL nickname. Otherwise there will be invalid
1403 memory as the nickname after the nickname is freed. Affected
1404 file silcd/packet_receive.c.
1406 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1407 saved into wrong slots because the previous number of entries
1408 was not taken into account. Affected file silcd/idlist.c.
1409 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1411 * If we are router and we receive JOIN notify to a channel that
1412 does not have any users then notified client is marked as the
1413 channel founder, as it is it. The affected file is
1414 silcd/packet_receive.c
1416 * Added to the extended hash table API's table_del_*ext functions
1417 the destructor as argument too, so that the caller can decide
1418 which destructor to use or whether to use destructor at all.
1419 Affected file lib/silcutil/silchashtable.[ch].
1421 * Fixed ID Cache purging. It actually deleted the entries from
1422 the hash table after the data was freed. The hash table ended
1423 up comparing freed memory. The affected file is
1424 lib/silccore/silcidcache.c.
1426 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Fixed Irssi SILC client's KILL command's HELP syntax.
1430 * The USERS command now resolves the detailed user information
1431 if the userinfo field is missing. Affected file is
1432 lib/silcclient/command_reply.c.
1434 * Do not print error in silc_file_read if the read file does
1435 not exist. Just silently return NULL. Affected file is
1436 lib/silcutil/silcutil.c.
1438 * Fixed the silc_log_output to not wine about NULL filename
1439 and to not create some bogus " " filename. Affected file is
1440 lib/silcutil/silclog.c.
1442 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Fixed various printing bugs on the user interface in the
1445 Irssi SILC Client. Minor changes that were forgotten from
1448 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Fixed the configure.in.pre and the compilation and distribution
1451 environment to support the new autoconf 2.52. That version is
1452 now required to compile the CVS trunk.
1454 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1457 to generally parse user@fqdn format strings. Affected file
1458 lib/silcutil/silcutil.c.
1460 * Added nickname_format and nickname_force_format fields to the
1461 SilcClientParams structure. The first one defines the format
1462 for the nicknames that the library will enforce if the receives
1463 multiple same nicknames. The second one is boolean value and
1464 can be used to force the library to always enforce the format
1465 to the nicknames regardles whether there are multiple nicknames
1466 or not. This configurable formatting was employed to flexibly
1467 support accessing multiple nicknames from the user interface.
1468 The userinterface can now set the nicknames to what ever format
1469 they prefer. Affected file lib/silcclient/silcapi.h.
1471 Added function silc_client_nickname_format to the file
1472 lib/silcclient/idlist.c. It performs the nickname formatting.
1474 Added new field `hostname´ to the SilcClientEntry context.
1475 It holds the hostname of the client. Affected file is
1476 lib/silcclient/idlist.h.
1478 * Irssi SILC Client sets the nicknames in nick@hostn format.
1479 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1480 irssi/src/silc/core/silc-core.c.
1482 The WHOIS printing now also shows both the real nickname and
1483 the formatted nickname so that user knows how to access the
1484 user if there are multiple same nicknames cached. Affected
1485 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1486 printing formatting too to take the hostname now as a separate
1487 argument. The Affected file is
1488 irssi/src/fe-common/silc/modules-formats.[ch].
1490 * Changed the silc_client_get_clients_local to accept the formatted
1491 nickname as argument. It accepts the real nickname too but the
1492 formatted nickname can be used to find the true entry from
1493 multiple entries. Affected file lib/silcclient/silcapi.h and
1494 lib/silcclient/idlist.c.
1496 * Added nickname_format_parse field to the SilcClientParams.
1497 It is a callback function provided by the application to parse
1498 the nickname out of the formatted nickname string. The library
1499 calls it to get the nickname from the formatted string. Since
1500 the application generally knows better the format of the nickname
1501 string it parses it instead of the library, even though library
1502 encodes the formatted string. If the callback function is not
1503 provided then the library will use the string as is. The
1504 affected file is lib/silcclient/silcapi.h.
1506 * All the nickname strings passed to the client library in
1507 commands are now expected to be formatted nickname strings.
1508 If the command does not support the formatted nickname string
1509 it will assume that the sent string is the actual nickname.
1510 Affected file lib/silcclient/command.c.
1512 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Added public key authentication support to OPER and SILCOPER
1515 commands in the client library. Affected file is
1516 lib/silcclient/command.c.
1518 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Changed the get_auth_methdod client operation to be asynchronous.
1521 It can be async if the application resolves the authentication
1522 method from the server during the negotiation. Added new
1523 SilcGetAuthMeth completion callback that the application will
1524 call after resolving the authentication method.
1526 Added function silc_client_request_authentication_method that
1527 the application can use to resolve the authentication method
1528 from the server. Added also SilcConnectionAuthRequest callback
1529 that the library will call after the server has replied. The
1530 application can call this function if it does not know the
1531 current authentication method.
1533 Affected files are lib/silcclient/client.c and
1534 lib/silcclient/silcapi.h.
1536 * The Irssi SILC client now automatically resolves the authentication
1537 method incase any configuration information is not present (and
1538 currently there never is). The affected file is
1539 irssi/src/silc/core/client_ops.c.
1541 * Fixed public key authentication from the client library.
1542 Affected file lib/silcclient/protocol.c. Changed also the
1543 protocol specification about the public key authentication in
1544 the connection authentication protocol. The actual data to be
1545 signed is now computed with a hash function before signing.
1547 * Fixed the public key authentication from the server as well.
1548 Affected file silcd/protocol.c.
1550 * Removed the mlock()'s from the memory allocation routines.
1551 Affected file lib/silcutil/silcmemory.c. The ./configure does
1552 not check anymore for the mlock(). Affected file is
1555 * Fixed USERS command in server to allow the execution of the
1556 command for private and secret channels if the client sending
1557 the command is on the channel. Affected file silcd/command.c.
1559 * Fixed silc_client_get_clients_local to return the clients
1560 count correctly. It could return wrong value. Affected file
1561 lib/silcclient/idlist.c.
1563 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1566 types. The assembler optimizations seemed not to like 64-bit
1567 data types. The assmebler optimizations thus are now enabled
1568 also for BSD systems as opposed to only enable them for Linux.
1570 * Do not check for threads at all on BSD systems. Affected
1571 file configure.in.pre.
1573 * Removed -n and -h options from the Irssi SILC Client since
1574 they are not used in silc.
1576 * Fixed the prime generation to assure that the first digit
1577 of the generated random number is not zero since our conversion
1578 routines does not like number strings that starts with zero
1579 digit. If zero digit is seen the random number is regenerated.
1580 This caused some corrupted RSA keys when the zero first digit
1581 was met. Affected file lib/silcmath/silcprimegen.c.
1583 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Fixed WIN32 configuration in the ./configure script.
1586 Fixed to include xti.h on environments that has it.
1587 Patches by Carsten Ilchmann and andrew.
1589 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Changed the silc_id_create_client_id to be collision
1592 resistant. It is now assured that there cannot be created
1593 two same client ID's. I suspect that some weird bugs in
1594 the server were actually caused by duplicate Client IDs.
1595 Affected file silcd/serverid.[ch]. A router receiving
1596 new ID now also assures and informs the sending server
1597 if the ID caused collision.
1599 * Changed the silc_id_create_channel_id to also assure that
1600 there are no collisions.
1602 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1604 * Statement about ignoring the Mutual Authentication flag when
1605 performing rekey with PFS was a bit misleading. It is ignored
1606 if it was set in the initial negotiation, it cannot be even
1607 set in the rekey. Fixed in the ke-auth draft. Started the
1608 new versions of the protocol drafts in the doc/.
1610 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Fixed a bug in silc_client_command_identify_save when saving
1613 new channel information. The channel name was no duplicated
1614 and caused crash on exit. Affected file is
1615 lib/silcclient/command_reply.c.
1617 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Fixed the getkey command handling in the server. Send just
1620 empty OK reply to the sender if the key could not be fetched
1621 (but everything else was ok, like the key just was not available).
1622 Changed the public key parameter to optional in the protocol
1623 specs so that empty OK reply can be sent. Affected file
1626 Added a message to Irssi SILC client to tell to user if the
1627 server did not return a public key.
1629 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Fixed a channel key regeneration bug. It registered new
1632 timeout tasks exponentially until all system resources were
1633 used. Affected file silcd/server.c.
1635 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Added the SILC Document generator to the scripts/silcdoc.
1638 It can be used to generate the Toolkit Reference Manual out
1639 of the source tree. Internally it will also use the RoboDoc
1640 generator now imported in util/robodoc.
1642 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Added couple of return's in rekey protocol if error orccurred
1645 during the protocol. The execution must be terminated.
1646 Affected file silcd/protocol.c. Also, terminate the protocol
1647 always with timeout.
1649 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * The client's Client ID was created initally from the wrong
1652 nickname (it could have been in format nick@host) in the
1653 silc_server_new_client. Affected file silcd/packet_receive.c
1655 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Added some SILC_LOG_ERROR's to various error conditions
1658 if client could not be added to ID cache. Affected files
1659 silcd/packet_receive.c and silcd/server.c.
1661 * When client's sock->user_data is freed, NULL also the
1662 client->router and client->connection pointers. Added check
1663 for these pointers being NULL to various places around the
1664 code. Affected file silcd/server.c.
1666 * Added client->data.registered == TRUE checks to various
1667 places around the code to assure that unregistered client's
1668 are not handled when it is not allowed. Affected file
1671 * Added `bool registered' fields to all
1672 silc_idlist_[server|client]_get_* routines to indicate whether
1673 the fetched client needs to be registered or not. Affected
1674 file silcd/idlist.[ch].
1676 * Add your own entry as registered to the ID cache in the
1677 server. Affected file server.c.
1679 * Fixed a bug in silc_server_new_server. The SilcServer was
1680 set as the new server's context instead of SilcServerEntry.
1681 This naturally caused some weird bugs.
1683 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Do not delete the channel rekey task when adding it
1686 for in silc_server_create_channel_key.
1688 * Changed the silc_server_create_channel_key to return
1689 TRUE or FALSE to indicate the success of the channel key
1692 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Fixed MSVC++ project files and added missing files to

1700 does not have it defined. Affected files are
1701 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1703 * Fixed buffer overflow from Irssi SILC Client. Affected
1704 file irssi/src/fe-common/core/themes.c.
1706 * Fixed double free in client library in the file
1707 lib/silcclient/client.c when disconnecting from server.
1709 * Applied double free patch from cras to Irssi SILC client.
1710 Affected files irssi/src/core/[modules/expandos].c
1712 * Fixed the disconnection handling to Irssi SILC Client.
1713 The application must call silc_client_close_connection
1714 in ops->connect client operation in case of failure of
1715 the connection. Affected file is
1716 irssi/src/silc/core/client_ops.c.
1718 * Do not set sock->protocol to NULL in the function
1719 silc_client_close_connection after executing the protocol's
1720 final callback since the sock might not be valid anymore.
1721 Affected file lib/silcclient/client.c.
1723 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Do not enable SILC_THREADS if the linking with libpthread
1726 did not happen. Affected file configure.in.pre.
1728 * Added notion to protocol specification that server must
1729 verify the sent authentication payload with CMODE when
1730 setting the channel founder key. Implemented it to the
1731 server. Affected file silcd/command.c.
1733 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Added _EXTRA_DIST SILC distribution variable to the
1736 distributions file. It is used to conditionally add extra
1737 files or directories to the specific distribution. Affected
1738 files ./prepare, Makefile.am.pre and distributions.
1740 Removed the `_' from the start of the distribution names.
1743 * Added README.WIN32 for instructions to compile the Toolkit
1746 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Fixed a double free in disconnection in the server. Affected
1749 file is silcd/server.c.
1751 * Fixed the lib/silcske/groups.c to work now also with GMP
1752 MP library. The string conversion did not work when using
1753 specific base and the base is indicated in the string as well.
1755 * Created win32/ directory which now includes MSVC++ specific
1756 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1757 It will appear only in the toolkit distribution
1759 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Changed the key material distribution function in case when
1762 the hash output is too short. The data is now concatenated
1763 a bit differently than it used to. Made the change to the
1764 SKE protocol specification.
1766 * Added better GMP detection to configure.in.pre. A patch
1769 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Fixed a minor bug in SKE that might cause some problem on
1772 some platforms. Affected file lib/silcske/silcske.c.
1774 * Added the cookie checking for initiator in the SKE. It checks
1775 that the responder returns the sent cookie unmodified. The
1776 affected file is lib/silcske/silcske.c. Added new SKE
1777 error type INVALID_COOKIE that can be sent during the
1778 negotiation. Fixed some memory leaks as well.
1780 * Added the "invalid cookie" error message to Irssi SILC client's
1783 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Added `task_max' field to the SilcClientParams to indicate
1786 the maximum tasks the scheduler can handle. If set to zero,
1787 default values are used. Affected file lib/silcclient/silcapi.h.
1789 * Fixed memory leaks in silc_client_close_connection. Affected
1790 file lib/silcclient/client.c.
1792 * Added silc_client_del_client_entry to client library to free
1793 all memory of given client entry. Affected file is
1794 lib/silcclient/idlist.[ch].
1796 * Added new functions silc_client_del_channel and
1797 silc_client_del_server to delete channel and server entries.
1798 Affected file lib/silcclient/[silcapi.h/idlist.c].
1800 * Removed silc_client_del_client_by_id from silcapi.h.
1802 * Fixed the INFO command to return the server's own info
1803 correctly when querying by Server ID. Affected file is
1806 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Removed the non-blocking settings in WIN32 code in the
1809 silc_sock_[read/write] and added SleepEx instead. Affected
1810 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1811 of input data is now checked with FIONREAD and ioctlsocket.
1813 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1815 * Call silc_schedule_task_del_by_context in the
1816 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1817 Affected file lib/silccore/silcprotocol.c.
1819 * Call silc_protocol_cancel for active protocols in the
1820 silc_server_close_connection if the funtion
1821 silc_server_free_sock_user_data has not been called.
1822 Affected file silcd/server.c.
1824 * Generic tasks cannot be deleted using the del_by_fd
1825 task deleting function since generic tasks does not match
1826 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1828 * Added a notion to SILCOPER help file that the SILCOPER works
1829 only on router server, not on normal server.
1831 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Added for WIN32 support for the new scheduler as well.
1834 Affected file lib/silcutil/win32/silcwin32schedule.c.
1836 * Fixed the SHA1 implementation to work on various platforms.
1838 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1841 API. It is part of the scheduler now. Everything else is
1842 as previously but some functions has changed their names.
1843 Checkout the lib/silcutil/silcschedule.h for the interface.
1844 Updated all applications to use the new interface. Affected
1845 files are lib/silcutil/silcschedule.[ch].
1847 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Found a bug in the SKE implementation. The HASH value,
1850 specified by the protocol, was not computed correctly. The
1851 public key of the responder was not added to the computation
1852 even though it is mandatory. Affected file lib/silcske/silcske.c.
1853 This unfortunately causes incompatibilities with older
1854 clients and servers.
1856 * Added WIN32 specific network init and uninit functions:
1857 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1858 the Winsock2. Affected file lib/silcutil/silcnet.h and
1859 lib/silcutil/win32/silcwin32net.c.
1861 * Set the socket always to nonblocking mode on WIN32 after
1862 reading data or writing data. Affected file is
1863 lib/silcutil/win32/silcwin32sockconn.c.
1865 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * Fixed various compilation problems under WIN32. Affected
1868 files lib/silcutil/win32/silcwin32thread.c and
1869 lib/silcutil/win32/silcwin32schedule.c.
1871 * Removed all _internal.h #includes from public header
1872 files. Internal headers must never be included from
1875 Removed also the lib/silcske/payload_internal.h file.
1877 * All include files that may be needed (public and some others
1878 included by the public headers) by application developers are
1879 now copied to the ./includes directory. It does not copy any
1880 internal headers. Affected file Makefile.defines.pre and all
1881 Makefile.am's under lib/ and subdirs.
1883 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Do not change the ~/.silc directory's permissions automatically.
1886 Affected file irssi/src/silc/core/clientutil.c.
1888 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Do not cancel the protocol in silc_server_close_connection
1891 it might cause recursion. Now cancelled in the function
1892 silc_server_free_sock_user_data. Affected file silcd/server.c.
1894 * Fixed the silc_server_remove_clients_by_server to regenerate
1895 the channel keys correctly finally. Added also new function
1896 silc_server_remove_clients_channels to actually do it.
1897 Affected file silcd/server.c.
1899 * Fixed the silc_server_new_channel to not crash by giving
1900 wrong router to the new channel. Affected file is
1901 silcd/packet_receive.c.
1903 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1905 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1906 which is given as argument to the silc_client_alloc now.
1907 It can be used to configure the client and set various parameters
1908 that affect the function of the client.
1910 * The USERS command in server did not check whether the channel
1911 is private or secret. Affected file silcd/command.c.
1913 * Added new argument to the USERS command in protocol specification.
1914 The USERS command now can take the channel name as argument
1915 as well. Added support for this in client and server and
1916 updated the protocol specs.
1918 * Completed the GETKEY command in client. It can be now used
1919 to fetch also servers public key not only some clients.
1920 Affected files lib/silcclient/command[_reply].c.
1922 * Added silc_client_get_server to return server entry by the
1923 server name. Affected files lib/silcclient/silcapi.h and
1926 * Redefined the IDENTIFY command in protocol specification to be
1927 more generic. It now can be used to query information about
1928 any entity in the SILC Network, including clients, servers and
1929 channels. The query may be based either the entity's name
1930 or the ID. Added support for this in both client and server.
1932 Affected files silcd/command.c and lib/silcclient/command.c
1933 and command_reply.c.
1935 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1936 the _from_client and _from_server functions. Affected file
1939 * Added silc_client_get_channel_by_id_resolve to the file
1940 lib/silcclient/silcapi.h to resolve channel information by
1941 its ID. Added also silc_client_get_channel_by_id that
1942 does not resolve it from the server.
1944 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Added SilcServerEntry context into the client library
1947 to represent one server. The INFO command now allocates
1948 these to save the resolved server info. For now on the
1949 client library will also keep information about servers,
1950 connected and resolved with INFO.
1952 The INFO command now allocates the SilcServerEntry context
1953 and saves the server info there. The COMMAND_REPLY in
1954 the INFO now returns the parameters to application in
1955 same order as defined in the protocol specification.
1957 The entries are cached in the client->server_cache.
1959 * The INFO command is now issued after received the Client ID
1960 from the server. Affected file lib/silcclient/client.c.
1962 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1963 to the application as the mode changer might be server.
1964 It is guaranteed that NULL is not returned anymore to the
1965 application. Affected file lib/silcclient/client_notify.c.
1967 The ID Type is now also passed to the application so that
1968 it can check whether the returned entry is SilcClientEntry
1971 Added new function silc_client_get_server_by_id to return
1972 the server entry by ID. Affected files are the
1973 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1975 * Do not create the channel in the Irssi SILC Client when issuing
1976 the JOIN command but when received the sucessful JOIN command
1977 reply. Otherwise the channel might get created even though we
1978 could not join it. The Affected file is
1979 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1981 * Fixed a channel joining bug in router. The router must also
1982 check the channel modes, invite and ban lists etc. when serving
1983 the JOIN command sent by normal server. Affected file is
1984 silcd/command.c. The router now resolves the client's
1985 information from the server who sent the JOIN command if it
1986 does not know it, and processes the JOIN command only after
1989 * Changed the SilcCommandCb to take new argument; void *context2.
1990 Affected file lib/silccore/silccommand.h
1992 The second argument in the command callbacks in the server now
1993 includes the SilcServerCommandReplyContext if the command was
1994 called as pending command callback from the command reply.
1995 Otherwise it is NULL. When called as pending the status of the
1996 command reply will be checked and if it was erronous the
1997 error will be sent to the original sender of the command.
1998 This way the client always receives the error messages even
1999 though the server was actually the one who received the error
2000 when it resent the command to router, for example. Affected
2001 files silcd/command[_reply].[ch].
2003 * Fixed sending WHOWAS command's error message to client if
2004 the requested client could not be found. It was missing.
2007 * Changed the CMODE and CUMODE commands reply arguments in the
2008 protocol specification. The Channel ID is now sent in both
2009 of the commands to identify the channel. Implemented this
2010 new feature to the client and server. Affected files
2011 lib/silcclient/command_reply.c and silcd/command.c.
2013 * Made better checks for invite and ban lists in the JOIN
2014 command in server. Affected file silcd/command.c.
2016 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2018 * The server now performs the incoming host IP/DNS lookup
2019 using the silc_socket_host_lookup and thus does not block
2020 the server anymore. Affected file silcd/server.c.
2022 * Completed the multi-thread support for SILC Scheduler in
2023 the lib/silcutil/silcschedule.c.
2025 * Fixed the configure.in.pre to detect the pthread correctly
2028 * Fixed a deadlock in silc_task_queue_wakeup in the file
2029 lib/silcutil/silctask.c.
2031 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Added new function silc_schedule_wakeup that is used in
2034 multi-threaded environment to wakeup the main thread's
2035 schduler. It needs to be used when a thread adds a new task
2036 or removes a task from task queues. After waking up, the
2037 scheduler will detect the task queue changes. If threads
2038 support is not compiled in this function has no effect.
2039 Implemented the wakeup mechanism to both Unix and WIN32
2040 systems. Affected files are lib/silcutil/silcschedule.[ch],
2041 lib/silcutil/unix/silcunixschedule.c and the
2042 lib/silcutil/win32/silcwin32schedule.c.
2044 * Added new function silc_task_queue_wakeup to wakeup the
2045 scheduler by the specified task queue. Affected file
2046 lib/silcutil/silctask.[ch].
2048 * The silc_socket_host_lookup_start now wakes up the scheduler
2049 after adding the timeout task. Affected file is
2050 lib/silcutil/silcsockconn.c.
2052 * The silc_socket_host_lookup is synchronous now if the threads
2053 support is not compiled in. However, the callback is still
2054 called asyncronously through the scheduler, anyway. Affected
2055 file lib/silcutil/silcsockconn.c.
2057 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Added new function silc_socket_host_lookup to perform
2060 asynchronous IP and FQDN lookups for the socket connection.
2061 Affected files lib/silcutil/silcsockconn.[ch].
2063 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2066 that may or may not compile the mutex support in.
2068 Changed the silc_mutex_alloc interface. It allocates the
2069 mutex now to the sent pointer and returns TRUE or FALSE.
2071 Affected file lib/silcutil/silcmutex.h.
2073 * Wrote the SILC Task Queue interface to support multi-threads.
2074 Affected file lib/silcutil/silctask.[ch].
2076 * Wrote the SILC Scheduler to support multi-threads. Affected
2077 file lib/silcutil/silcschedule.c.
2079 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2082 in lib/silcutil/win32/.
2084 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Defined SILC Mutex API and SILC Thread API and implemented
2087 them for Unix. Affected files are
2088 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2089 lib/silcutil/unix/silcunixmutex.c and
2090 lib/silcutil/unix/silcunixthread.c.
2092 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Fixed the silc_server_remove_clients_by_server's channel
2095 key re-generation. The hash table handling was incorrect
2096 and would not work with many channels. Affected file is
2099 * Fixed some memory leaks around the server code.
2101 * Rewrote the silc_server_get_users_on_channel to support IPv6
2102 based Client ID's. Affected file silcd/server.c.
2104 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2105 specification. However, a separate document must be written
2106 to define the detailed signing procedure and the payload
2107 associated with the flag. Defined the flag to the
2108 lib/silccore/silcchannel.h as well.
2110 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Changed the dynamic tables to static size tables in the
2113 lib/silccrypt/silchmac.c.
2115 * Removed GCC dependencies from the code. A patch by cras.
2117 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Do not show the error "Error receiving packet bla bla"
2120 in server if it really was not an error (-2 means that reading
2121 is pending). Affected file silcd/server.c.
2123 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Fixed a possible crash in silc_server_remove_clients_by_server
2126 in silcd/server.c. Fixed there also some memory leaks.
2128 * Fixed the silc_idlist_replace_client_id. It could replace
2129 wrong key in the hash table. Affected file silcd/idlist.c.
2131 * Do not check whether there are global users on the channel
2132 if the channel->global_users is FALSE. Affected functions
2133 silc_server_remove_from_one_channel and
2134 silc_server_remove_from_channels in silcd/server.c. Also,
2135 do not check if the removed client is local as we can be
2136 sure that global client was not removed from the channel
2137 and checking for global users is not needed.
2139 * The silc_server_remove_clients_by_server now re-generates
2140 the channel keys correctly for those channels that had
2141 clients removed from them. Affected file silcd/server.c.
2143 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Found the reason of random crashes in the server. We weren't
2146 ignoring the SIGPIPE signal (which can be sent in write())
2147 and it crashed the server. Affected file silcd/silcd.c.
2149 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2151 * Assure that sock->user_data is not NULL in the function
2152 silc_server_packet_send in silcd/packet_send.c.
2154 * Disconnect the remote connection if it could not be added
2155 to any ID lists in the server. The affected file is
2158 * Check in silc_server_packet_send[_real/dest] that the
2159 socket is not disconnecting and ignore the data if it is.
2160 Affected file silcd/packet_send.c.
2162 * Define inline to __inline on native WIN32 compilation.
2163 Affected file includes/silcwin32.h.
2165 * Added some explicit type casts for inline code since MSVC
2166 require them. Affected files lib/silcutil/silcbuffer.h,
2167 lib/trq/silcdlist.h and lib/trq/silclist.h.
2169 * Print warning in log files from now on if the packet
2170 decryption fails. Affected file silcd/server.c.
2172 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Changed the `say' client operation's interface to accept
2175 new `type' argument to indicate the type of the message sent
2176 by the library. The application may filter the library's
2177 messages according the type. The affected file is the
2178 lib/silcclient/silcapi.h.
2180 * Added two new functions to lib/silcclient/silcapi.h:
2181 silc_client_del_client and silc_client_del_client_by_id.
2182 Affected file lib/silcclient/idlist.c.
2184 * Moved the clientincludes.h from includes/ to silc/ and
2185 serverincludes.h from includes/ to silcd/.
2187 * The modes for the CMODE and CUMODE are now passed as
2188 uint32 for application with COMMAND_REPLY. The affected
2189 file is lib/silcclient/command_reply.c.
2191 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2193 * /WHOIS without arguments shows client's own information.
2194 Affected file lib/silcclient/command.c.
2196 * Changed PING to not accept any arguments. The specs
2197 says that client can ping only the connected server so
2198 requiring an argument is not needed. Affected file is
2199 lib/silcclient/command.c.
2201 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Fixed a fatal bug in private message sending and reception
2204 encryption and decryption when using private message keys.
2205 The implementation was incorrect and did not follow the
2206 specification. It causd that some of the message were
2207 lost since it did not use the sending and receiving keys
2208 as the protocol suggests. This has been fixed and will cause
2209 incompatibilities with older clients when sending private
2210 message encrypted with private message keys. Affected files
2211 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2212 and various other in Irssi SILC Client.
2214 Added `responder' boolean argument to the functions
2215 silc_client_add_private_message_key[_ske] to indicate when
2216 the key is added as responder or initiator of the key
2219 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Removed the silc_ske_check_version function and created
2222 a SilcSKECheckVersion callback. Added also a function
2223 silc_ske_set_callbacks that is now used to set all SKE
2224 callbacks. The callback functions are not given to
2225 the SKE functions anymore, but this function is used to
2228 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2230 * Added `silc_version' argument to the silc_client_alloc
2231 to define the version of the application for the library.
2232 The library will use the version string to compare it
2233 against the remote host's (usually a server) version
2234 string. Affected file lib/silcclient/silcapi.h
2236 * Added the KE protocol context to Key Agreement context
2237 in client library so that we can abort the SKE if it
2238 is in process when we get timeout. Affected file is
2239 lib/silcclient/client_keyagr.c.
2241 * Do not resolve the client ID forever if it returns in the
2242 first time that such client does not exist. This was done
2243 for example with private message. Affected file is
2244 lib/silcclient/client_prvmsg.c.
2246 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Do not add regex.h for WIN32. The affected file
2249 includes/silcincludes.h.
2251 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2252 not work yet 100%. It generates the DLL's automatically
2253 when compiling with --with-win32 under cygwin.
2255 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * lib/contrib/regex.c is not compiled on WIN32.
2259 * Added silc_net_get_socket_opt function to the
2260 lib/silcutil/silcnet.h.
2262 * Added includes/silcwin32.h for WIN32 specific includes
2265 * Do not use ptime structure or any of the posix process
2266 functions on WIN32 in lib/silccrypt/silrng.c.
2268 * Added silc_gettimeofday to provide generic function
2269 for struct timeval on all platforms. Added the function
2270 to lib/silcutil/silcutil.h.
2272 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2275 library as they clearly belong there. As a plus side we
2276 can make the actual socket connection routines platform
2279 Added also new generic function silc_socket_read and
2280 silc_socket_write (that used to be silc_packet_[read/write].
2281 The implementation of these are platform specific.
2283 * Added WIN32 specific routines of silc_socket_[read/write]
2284 to lib/silcutil/win32/silcwin32sockconn.c.
2286 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Added preliminary support for native WIN32 compilation under
2289 cygwin (using the -mno-cygwin option for GCC) to the
2290 ./configure.in.pre. The --with-win32 now prepares the
2291 compilation for native WIN32.
2293 * Rewrote the SILC Scheduler interface in the file
2294 lib/silcutil/silcschedule.h. The scheduler is now context
2295 based and does not have anymore any global static scheduler.
2296 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2297 and created lib/silcutil/win32 directory for WIN32 based
2300 * Added Unix specific network routines to the
2301 lib/silcutil/unix/silcunixnet.c and the old
2302 lib/silcutil/silcnet.c includes now only generic routines.
2304 Added WIN32 specific network routines to the
2305 lib/silcutil/win32/silcwin32net.c.
2307 * Added Unix specific utility functions from the
2308 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2310 * Added WIN32 SILC Scheduler to the file
2311 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2314 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Do not handle JOIN notify in the server if the target client
2317 is not registered (idata->registered == FALSE). The affected
2318 file is silcd/packet_receive.c.
2320 * Update the nickrec->founder in event_cumode in the Irssi SILC
2321 client. Affected file irssi/src/silc/core/silc-channels.c.
2323 * Fixed the CUMODE_CHANGE notify handling in the server when
2324 server and router are announcing their clients on channels.
2325 Now the mode changes are saved and notified correctly. The
2326 affected file is /silcd/packet_receive.c.
2328 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2329 They really did not replace the cache entry in the ID Cache.
2330 Now they do that. Affected file silcd/idlist.c.
2332 * Fixed the KICK notify handling in the Irssi SILC client to
2333 update the channel records so that the kicked client does not
2334 appear to be on the channel. The affected file is
2335 irssi/src/silc/core/silc-channels.c.
2337 * Always update the conn->current_channel when executing command
2338 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2340 * Fixed the KILL notify handling in Irssi SILC client to remove
2341 the killed client on all channels.
2343 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Fixed the silc_parse_command_line to remove extra spaces
2346 from the start and end of the arguments. Affected file is
2347 lib/silcutil/silcutil.c.
2349 * Cancel and free any active protocol in the function
2350 silc_server_close_connection. Affected file silcd/server.c.
2352 * Cancel and free any active protocol in the function
2353 silc_client_close_connction. Affected file is
2354 lib/silcclient/client.c.
2356 * Do not execute the KILL command for clients that are in
2357 history (ie. they are not in the network). Affected file is
2360 * Fixed KILL notify handling, client does not crash anymore.
2361 Affected file irssi/src/silc/core/silc-channels.c.
2363 * Reduced the default packet buffer size from 2048 to 1024 in
2364 lib/silccore/silcpacket.c.
2366 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2367 counter to the SKE context that is incresed when the SKE library
2368 performs async operation outside the library. If the outside
2369 process frees the SKE context and FREED status will be set
2370 and the library will detect after the sync operation that the
2371 libary is freed. The affected files are
2372 lib/silcske/silcske[_status].[ch].
2374 * Resolve the client entry information in the function
2375 silc_client_channel_message to assure that NULL pointer is not
2376 passed as client entry to the application. */
2378 * Fixed the task timeout calculation to assure that there is
2379 never negative timeouts. The affected file is
2380 lib/silcutil/silcschedule.c.
2382 * Fixed the channel user mode notification sending in server.
2383 It was sent point-to-point to the router (or to server by router)
2384 but it needs to be destined to a channel. The routines now
2385 supports sending the channel user mode notifys to the channels
2386 when announcing clients and channels. Affected files are
2387 silcd/server.c and silcd/packet_receive.c.
2389 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2390 It did not actually replace the old channel entry in the cache.
2391 Affected file lib/silcclient/client_notify.c.
2393 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Fixed a possible crash in silc_packet_send_prepare. It now
2396 assures always that there is enough space in the buffer and
2397 at the tail area of the buffer (for MAC).
2399 Fixed the inbound buffer reallocation in silc_packet_read.
2400 It was old code and did not handle the reallocation correctly.
2403 The affected file is lib/silccore/silcpacket.c.
2405 * Fixed buffer overflow in silc_parse_nickname in the file
2406 lib/silcutil/silcutil.c.
2408 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * make install generates new server keys only if there is not
2413 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2416 Added check that if the NOREPLY is set then we will not send
2417 the away message. This avoids infinite loop of away messages
2418 if both clients are away. The affected file is
2419 lib/silcclient/client_prvmsg.c.
2421 * Fixed client crash if /NICK was given without arguments.
2422 Affected file lib/silcclient/command.c.
2424 * Server does not send the invite list in INVITE command back
2425 to the client if the list was not altered. Added this notion
2426 to the protocol spec as well. Affected file silcd/command.c.
2428 Fixed possible crash in INVITE command by checking the
2429 value of silc_server_get_client_route command.
2431 * Fixed the INVITE notify type handling. The arguments are now
2432 taken in correct order and client does not crash. The affected
2433 file is irssi/src/silc/core/silc-channels.c.
2435 Removed the "Inviting xxx to channel" message from the
2436 client library away and let the application handle it.
2437 Affected file lib/silcclient/command.c. Added that message
2438 to Irssi SILC client's message formats.
2440 * Fixed CMODE command crash in client. It now checks the
2441 amount of arguments correctly and does not crash. The affected
2442 file is lib/silcclient/command.c.
2444 * Do not create new channel automatically in silc_channels_join
2445 but check whether the channel by that name already exists.
2446 Affected file irssi/silc/core/silc-channels.c.
2448 * Do not send the SERVER_SIGNOFF to router if the disconnected
2449 entity was the router. Affected file silcd/server.c.
2451 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2452 SILC client as it was missing from there.
2454 Added the handling of the KICK notify to the Irssi SILC client
2455 as it was missing. Added "you have been kicked" message to
2456 Irssi SILC client's message modules formats.
2458 Added the handing of the KILL notify to the Irssi SILC client
2459 as it was missing. Added the kill message module formats
2462 The affected file is irssi/src/silc/core/silc-channels.c.
2464 * The router did not save the channel mode the server announced.
2465 Affected file silcd/packet_receive.c.
2467 * Fixed a possible crash in INFO command in server. If the
2468 server did not provide the server info it crashed. Affected
2469 file silcd/command.c.
2471 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Fixed the GETKEY command in the server to check also the
2474 global list. Otherwise the GETKEY would not work correctly
2475 in normal SILC server. Affected file silcd/command.c.
2477 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Fixed GETKEY crash, it crashed if the command did not succseed.
2481 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2484 is now real and not just an macro interface to GMP.
2486 Removed the entire GMP from the source tree and imported new
2487 NSS MPI library instead. Reason for removing GMP is that it is
2488 extremely large and compiles extremely slow. The NSS MPI
2489 is only a few files and compiles in less than 10 seconds.
2490 The speed is also about the same as GMP. The MPI is imported
2491 to lib/silcmath/mpi.
2493 If the system has GMP installed we will still use the GMP.
2494 If it is not then the NSS MPI will be compiled.
2496 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Merged a long nickname (127 characters long) crash bugfix from
2499 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2501 * Merged a freed memory reference bugfix from Irssi CVS tree.
2502 Affected file irssi/src/core/commands.c.
2504 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Added the server's public key sving and verification to the
2507 server when performing the SKE. This was missing and the
2508 remote server's (or router's) public key was accepted without
2509 checking whether we have it previously or trust it at all.
2510 Affected file silcd/protocol.c.
2512 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Check in the silc_server_timeout_remote if protocol is active
2515 and make sure that the protocol's final callback is called so
2516 that all memory if freed. Affected file silcd/server.c.
2518 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2520 * silc_server_whois_send_reply crashed the server if the nickname
2521 was 127 characters long. Affected file silcd/command.c.
2523 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Added sanity check to the silc_server_new_client. If the hostname
2526 is provided inside username then check that the provided hostname
2527 really is the same as the resolved one. If the hostname was not
2528 resolved then check it from the public key. Affected file is
2529 silcd/packet_receive.c.
2531 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2532 if the server disconnected us and the connection is not valid
2533 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2535 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2536 the library to the lib/silcutil/silcutil.[ch].
2538 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Close log file after open. Affected file
2541 lib/silcutil/silclog.c.
2543 * Check whether sock == NULL in silc_client_send_packet and return
2544 if it is. Affected file lib/silcclient/silcclient.c.
2546 * Check rec->entry == NULL in the Irssi SILC Client before
2547 sending the channel message. Affecte file is
2548 irssi/src/silc/core/silc-servers.c.
2550 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Merged a splitted window bugfix from Irssi CVS tree. The
2553 affected file is irssi/src/fe-text/textbuffer-view.c.
2555 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2556 It did not print nickname.
2558 * Improved the distributions system a bit.
2560 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2563 irssi/src/fe-text/gui-window.c.
2565 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2566 to in-active server. The affected file is
2567 irssi/src/silc/core/client_ops.c.
2569 * Resolve the client in USERS command reply if the entry does
2570 not have username resolved. The affected file is
2571 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2572 command to WHOIS command to really resolve stuff. The USERS
2573 is not used any more in any critical section so WHOIS can
2574 be used even though it might be slower than IDENTIFY.
2576 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2579 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Changed the protocol API a bit more consistent in the
2582 lib/silccore/silcprotocol.[ch].
2584 * Changed the following headers to ROBODoc format:
2586 lib/silccore/silcpayload.h
2587 lib/silccore/silcprotocol.h
2588 lib/silccore/silcsockconn.h
2590 All core library headers are now formatted.
2592 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Fixed a bug in Irssi SILC client; do not show that you are
2595 server/router operator if you really are not. Affected file is
2596 irssi/src/silc/core/client_ops.c.
2598 * Renamed silc_command_free_payload to silc_command_payload_free.
2599 Affected file lib/silccore/silccommand.h
2601 * Added silcmath.h to include the prototoypes of various routines
2602 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2605 * Changed the following headers to ROBODoc format:
2607 lib/silccore/silcchannel.h
2608 lib/silccore/silccommand.h
2609 lib/silccore/silcid.h
2610 lib/silccore/silcidcache.h
2611 lib/silccore/silcmode.h
2612 lib/silccore/silcnotify.h
2613 lib/silccore/silcpacket.h
2614 lib/silcmath/silcmath.h
2616 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Added checking to the server code not to start the server if
2619 ciphers and stuff are not configured properly. Affected files
2620 silcd/serverconfig.[h] and silcd/server.c.
2622 * Changed the layout of the header files of the public interfaces
2623 in the SILC libraries. The new layout supports ROBODoc
2624 documentation tool (and some others) so that it is easy to create
2625 a library reference manual. All the other headers and source
2626 code must still follow the CodingStyle document. Also source
2627 code must not include these ROBODoc stuffs, only the headers.
2628 Furthermore, all public interface headers must now be named
2629 by using `silc' prefix, example: silcapi.h, silccipher.h.
2630 Some files were renamed due to this. All the other headers
2631 must not be used as public interfaces. I will update the
2632 CodingStyle document later. Changed following headers, so far:
2634 lib/silcclient/silcapi.h
2635 lib/silccore/silcauth.h
2636 lib/silccore/silcprivate.h
2637 lib/silccrypt/silcdh.h
2639 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Removed silc_client_packet_send_flush from the client library
2644 as it is not needed. Affected file lib/silcclient/client.[ch].
2646 * Added printing of message of unresolved authentication method
2647 to the Irssi SILC client. Added it to the module formats.
2648 Removed the same message from the client library.
2650 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added new distribution feature, DISTLABEL. Every distribution
2653 can define own preprocessor label that can be used in the
2654 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2655 file distributions, acconfig.h.pre and prepare.
2657 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Added Makefile.defines_int to include the actual definitions
2660 for Makefile.defines.in. Tested the new distribution system,
2661 created distributions and tested installation.
2663 * Added AWAY message printing to the Irssi SILC client. Added
2664 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2666 * Added SCONNECT command to call the SILC's CONNECT command.
2667 Cannot use CONNECT directly since Irssi uses that internally.
2668 Affected file irssi/src/silc/core/silc-servers.c.
2670 Added ACTION local command. It is same as ME command but takes
2671 the channel as mandatory argument.
2673 Rewrote some of the Irssi's help files to suite for SILC
2676 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Added Makefile.defines[.in] that should for now on be included
2679 in all Makefile.am file in the source tree. That file includes
2680 all common compilation definitions for SILC source tree.
2682 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * Minor changes to the ./prepare script to change the package
2685 name according the distribution name to the configure.in.
2687 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Created new distribution system. Added file `distributions'
2690 that defines all the distributions that can be created out of
2691 the SILC source tree. The ./prepare script now reads that
2692 file to determine how to prepare the distributions. The
2693 first argument to the ./prepare is the name of the distribution
2694 and second is the version of the distribution. If given
2695 without arguments it creates the default (toolkit) distribution
2696 with the default version (defined in ./prepare).
2698 All Makefile.am files that are subject to the distributions
2699 are now named as Makefile.am.pre. These are ./Makefile.am
2700 and lib/Makefile.am. Others may be changed later.
2702 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Added invite list, ban list, some key management and connection
2705 error message printing to module formats in the Irssi SILC client.
2707 * Added new silc_client_set_away_message to set the away message
2708 that is back to the person who sent private message. The
2709 affected file lib/silcclient/silcapi.h and the
2710 lib/silcclient/client_prvmsg.c.
2712 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Fixed the private message sending in the Irssi SILC client,
2715 added local command KEY to the Irssi SILC client.
2717 Added key management and key agreement message formats to the
2718 irssi/src/fe-common/silc/module-formats.[ch].
2720 Added USERS (alias WHO) printing, server/router operator
2721 indication and LIST command printing to the module formats.
2723 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Fixed channel joining notify handling, cumode notify handling
2726 from Irssi SILC client.
2728 * Added SILC specific module-formats to the Irssi SILC client so
2729 that SILC specific message hilighting, colors etc is possible.
2730 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2732 Added channel mode, channel user mode, actions, notices,
2733 whois and whowas printing to the the module-formats.c.
2735 * Fixed a bug in channel deletion in the server. The channel
2736 is not left to the cache even if the channel founder auth mode
2737 is set when there are no users anymore on the channel. Affected
2738 file silcd/server.c.
2740 * The silc_net_localhost now resolves the entire hostname including
2741 the domain name. Affected file lib/silcutil/silcnet.c.
2743 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Changed the ask_passphrase client operation to be ascynchronous.
2746 It has now a completion callback and a context that the
2747 application must call after it has got the passphrase from
2748 the user. Affected files lib/silcclient/silcapi.h,
2749 lib/silcclient/protocol.c, lib/silcclient/command.c and
2752 Added SilcAskPassphrase callback that the application calls
2753 to deliver the passphrase to the library.
2755 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2756 The public key verification and especially a certificate
2757 verification is asynchronous procedure.
2759 Added new SILC_SKE_STATUS_PENDING status to indicate the
2760 request is pending and a callback will be called to finalize
2763 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2764 indicate that remote end did not send its public key (or
2765 certificate), even though we require it. Added check for this
2766 condition in the SKE. This was a security bug, now fixed.
2768 Defined new SilcSKEVerifyCbCompletion callback that is called
2769 when the verification process is completed.
2771 The affected files lib/silcske/silcske_status.h and
2772 lib/silcske/silcske.[ch].
2774 * Changed the verify_public_key client operation to be async
2775 as well. Defined SilcVerifyPublicKey callback that is used to
2776 indicate the success of the public key verification process.
2778 Changed the server and client to use the new async client
2781 * Changed the Irssi SILC client's internal scheduler to be called
2782 twice as many times as it used to be. As a result the client
2783 should be a bit faster now. Affected file is
2784 irssi/src/silc/core/silc-core.c.
2786 * Added support to Irssi SILC client of asynchronous public key
2787 verification and passphrase inquiry. Affected file is
2788 irssi/src/silc/core/silc-core.c.
2790 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Do not say "You have left channel %s" in client library.
2793 Moved it to the application. Affected files are
2794 lib/silcclient/command.c and silc/client_ops.c.
2796 * Fixed silc_client_get_clients. Command context was not
2797 duplicated and was freed memory in the callback. Affected
2798 file lib/silcclient/idlist.c.
2800 * Do not say "you are now talking..." on JOIN command in the
2801 client library. The appliation must handle it.
2803 * Do not say ".. changed topic to" in command reply in the
2804 client libary. The application must handle it.
2806 * Fixed TOPIC command sending in the client library.
2808 * Fixed a memory leak in silc_client_command_free in the file
2809 lib/silcclient/command.c.
2811 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Imported a modified version of Irssi client to the source tree.
2814 The Irssi will be used to create a new client called
2815 Irssi SILC. Imported to irssi/.
2817 Added silc_core_init_finish function to the Irssi. Affected
2818 file irssi/configure.in.
2820 A lot changes in the Makefile.ams around the irssi tree.
2822 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Do not rehash if the new size is same as the old size of the
2825 hash table, in the silc_hash_table_rehash*. The affected file
2826 lib/silcutil/silchashtable.c.
2828 * Replaced hash_table_del_by_context calls from the server
2829 (when channel->user_list and client->channels) to the
2830 hash_table_del as it is sufficient and faster.
2832 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Added silc_hash_table_list, silc_hash_table_get and the
2835 SilcHashTableList structure to provide an alternative way to
2836 traverse the hash table. The affected files are
2837 lib/silcutil/silchashtable.[ch].
2839 * Changed the server's idlist routines to use the hash table
2840 routines to optimize the code.
2842 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Replaced the client entry's `channel' list and channel entry's
2845 `user_list' list to hash tables for optimized lookup. Changed
2846 the code to use the hash table interface around the code.
2847 Affected file lib/silcd/idlist.[ch].
2849 * Added `auto_rehash' boolean argument to the function
2850 silc_hash_table_alloc to indicate whether the hash table should
2851 auto-rehash when it thinks is appropriate time. It will
2852 increase the hash table size if the there is twice as much
2853 entries in the table than the size of the table, and will
2854 decrease the size if there are twice as less entries than
2855 the size of the table.
2857 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2861 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * silc_idcache_purge_by_context deletes the entry now by context
2864 as it is supposed to do. Affected file lib/silccore/idcache.c.
2866 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2867 client is not anymore valid (WHOWAS givens the info) and not
2868 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2870 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Removed the `data' and `data_len' arguments from the ID Cache
2873 interfaces and added `name' argument. ID Cache does not handle
2874 anymore the binary data only a names associated with given ID.
2876 * When hashing a Client ID with silc_hash_id the entire ID is
2877 not hashed anymore, instead only the hash of the Client ID is
2878 hashed. This way we can access the Client ID from the cache
2879 with Client ID but with the hash of the ID (which is a hash of
2880 the nickname) as well without any difference in performance.
2882 Added also silc_idcache_find_by_id_one_ext to do one on one
2883 searching when we have the actual ID. Added also function
2884 silc_hash_client_id_compare. The affected files are
2885 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2887 * When hashing the name associated with a ID it is always done
2888 in lowercase. This way we can access the cache without worrying
2889 about case-sensitivity, even though, for example nicknames are
2892 * Fixed a bug in server with channel message sending. It put
2893 wrong ID type as destination ID. The affected file
2894 silcd/packet_send.c.
2896 * silc_idcache_del_by_context now deletes from all hash tables
2897 by context. Affected file lib/silccore/idcache.c.
2899 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Changed the client library to use the new ID Cache interface.
2902 Changes around the source tree.
2904 * Added silc_hash_table_rehash_ext to rehash with specific
2905 hash function. Affected file lib/silcutil/silchashtable.[ch].
2907 * Added silc_hash_string_compare to compare two strings in the
2908 hash table. Affected file lib/silcutil/silcutil.[ch].
2910 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Added new function silc_idcache_del_by_context into the
2913 lib/silccore/idcache.[ch].
2915 * Changed the server's ID list routines to use the new ID Cache
2916 interface. Changes around the source tree.
2918 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Added silc_hash_table_del[_by_context]_ext functions in to the
2921 lib/silcutil/silchashtable.[ch].
2923 Removed silc_hash_table_find_all* routines and added new
2924 silc_hash_table_find_foreach to replace them.
2926 Added silc_hash_table_replace_ext function as extended
2927 replacing function. Separated the simple hash table interface
2928 from the extended hash table interface in the file
2929 lib/silcutil/silchashtable.h.
2931 * Fixed minor bugs and changed it to use some of the new
2932 hash table functions in lib/silccore/idcache.c
2934 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Added new function silc_hash_table_find_all to return all keys
2937 in the hash table by the specified key. As the hash table is
2938 collision resistant it also makes it possible to have several
2939 duplicate keys in the hash table. This function may be used to
2940 find all of the keys from the hash.
2942 Added user_context arguments to the SilcHashFunction,
2943 SilcHashCompare and SilcHashDestructor to deliver user specified
2946 Added new fuctions silc_hash_table_find[_all]_ext to do
2947 extended lookup with specified hash and compare functions and
2948 specified user contexts.
2950 Added new function silc_hash_table_add_ext to add the key
2951 with specified hash function and user context.
2953 Added new function silc_hash_table_foreach to traverse all
2954 entrys in the hash table. Added SilcHashForeach callback
2957 Added new function silc_hash_table_del_by_context to delete
2958 the entry only if the context associated with the key matches.
2960 Affected files are lib/silcutil/silchashtable.[ch].
2962 * Removed silc_hash_[server/client/channel]_id and added just
2963 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2964 silc_hash_id_compare to compare two ID's using as the hash table
2965 comparison function. Added also silc_hash_data to hash
2966 binary data and silc_hash_data_compare to compare it.
2968 * Removed silc_idlist_find_client_by_hash as it is not needed
2969 anymore. Affected file silcd/idlist.[ch].
2971 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2972 to use internally the SilcHashTable. The new ID Cache is a lot
2973 faster than the old one. Some of the ID Cache interface was also
2974 rewritten and obsolete and stupid functions were removed.
2976 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Added entry_count field to the SilcHashTable to keep the number
2979 of the entries in the table. Implemented the function
2980 silc_hash_table_rehash. Added new function
2981 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2983 Fixed a minor bug in silc_hash_table_free.
2985 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2986 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2987 into the lib/silcutil/silcutil.[ch].
2989 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2991 * Implemented a collision resistant hash table into the
2992 lib/silcutil/silchashtable[ch]. See the header and the source
2993 for the SilcHashTable API.
2995 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Merged dotconf version 1.0.2 into lib/dotconf.
2999 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Do not compile anything in lib/silcsim/* if the SIM support
3002 is not enabled. The tree should now compile without problems
3005 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Compiled the SILC under cygwin. Compiled and tested briefly
3008 without problems. More tests needed. The SIMs didn't compile
3011 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3013 * Fixed possible crash in silc_get_username in the
3014 lib/silcutil/silcutil.c.
3016 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed a va_arg in silc/client_ops.c.
3020 * Oops, RC5 routines were named AES and caused some problems
3021 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3023 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Added new SilcIDIP structure into the lib/silccore/id.h and
3026 replaced the old `ip' fields from all SILC ID's to that type.
3027 This is a step towards IPv6 support.
3029 The silc_id_get_len takes now the ID as an extra argument.
3030 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3031 both IPv4 and IPv6 based ID's.
3033 The affected files are lib/silccore/id.[ch] and other files
3034 around the tree using these routines.
3036 * Removed the ID length arguments in server from various
3037 silc_server_send_notify_* routines -> they are not needed
3040 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3042 * Fixed memory leak in silc_encode_pem_file in the file
3043 lib/silcutil/silcutil.c.
3045 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Check minor version as well in the SKE. Affected files are
3048 silcd/protocol.c and lib/silcclient/protocol.c.
3050 * Added --identifier option to the server so that an identifier
3051 can be when creating the public key for the server. Affected
3052 file is silcd/silcd.c.
3054 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3055 lib/silccrypt/silcpkcs.c.
3057 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Register default ciphers and stuff when using -C option with
3060 the server. Affected file sildc/silcd.c.
3062 * Put back the servers public key filename format, it is better
3063 than the new one. For now, the client keys are saved with the
3064 new filename format. The affected file silc/client_ops.c.
3066 * Implemented the Cipher API for the rest of the ciphers that
3067 did not implement it or implemented it the wrong way.
3069 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Register default ciphers and stuff when using the -S option
3072 in the client. Affected file silc/silc.c. Same also when
3073 creating new key pair with -C option.
3075 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Fixed the silc_verify_public_key client operation function to
3078 save the public keys differently. The fingerprint is now
3079 used as filename and not the hostname. This way also the
3080 client keys are saved uniquely and not with hostnames. The
3081 affected file is silc/client_ops.c.
3083 * Trimmed the silc_hash_fingerprint function to remove extra
3084 whitespaces from the end of the fingerprint. The affected
3085 file is lib/silccrypt/silchash.c.
3089 * Added silc_cipher_register_default function to register all
3090 default ciphers. It can be used when configuration files
3091 does not exist and the application does not want any specific
3092 ciphers in any specific order.
3094 The SilcDList is now used as silc_cipher_list dynamically
3095 allocated cipher list. Removed the static list all together
3096 and now all ciphers must be allocated to the dynamic list.
3097 The silc_cipher_alloc routine was changed to check only the
3100 All silc_cipher_* routines that used to return int returns
3103 The affected files lib/silccrypt/silccrypt.[ch].
3105 * The same thing was done to silc_hash_* as for silc_cipher_*
3106 routines. Affected files lib/silccrypt/silchash.[ch].
3108 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3109 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3110 Added also silc_pkcs_[un]register[_default] functions.
3111 Removed the data_context from the PKCS API.
3113 * Added silc_hmac_register_default function to register default
3114 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3115 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3116 to unregister all hmacs at once.
3118 * Register the default ciphers, hash functions, PKCSs and HMACs
3119 if client's configuration file does not exist. The affected
3122 * The client did not load the hash functions from the SIM
3123 modules at all. Added support for this. Affected file is
3124 silc/clientconfig.c.
3126 * When decoding public key with silc_pkcs_public_key_decode, check
3127 the supported algorithm only if PKCS are registered. Affected
3128 file lib/silccrypt/silcpkcs.c. The same was done with the
3129 silc_pkcs_private_key_decode.
3131 * Fixed the SILC List routines to keep the list always in order.
3132 It used to change the list's order when traversing the list but
3133 not it preserves the order. Affected file lib/trq/silclist.h.
3135 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Added the client library to use the SilcSocketConnection's
3138 reference counter (by silc_socket_dup) to prevent the bug that
3139 the socket object may be freed underneath async operation.
3141 * The name resolv library checking fixes in the configure.in.pre.
3144 * Created new version of the protocol drafts for future
3145 development. The -03 drafts are the ones that will be changed
3146 in the trunk now and the -02 will remain as they are.
3148 * Send list of CUMODE notifys to the router when announcing
3149 the channel users to the router. Affected file silcd/server.c.
3150 If the router receiving channel founder CUMODE for a channel
3151 that already has channel founder it will send CUMODE notify
3152 to the sender to remove the channel founder rights from the
3153 announced client. Affected file silcd/packet_receive.c.
3155 * The CUMODE notify may now use Server ID as well as the entity
3156 who changes the mode. Updated protocool specs.
3158 * Updated INSTALL and README files.
3160 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * New web pages in the http://silc.pspt.fi. The pages was
3167 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Implemented the [DenyConnectin] config section in the server.
3170 Added silc_server_config_denied_conn to check whether incoming
3171 connection is denied. Affected file silcd/serverconfig.[ch].
3173 * Do not check the ports when checking the incoming configuration
3174 data if the port is 0, meaning any. Affected file is
3175 silcd/serverconfig.c.
3177 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Fixed buffer overflow in silc_string_compare in the file
3180 lib/silcutil/silcutil.c.
3182 * Fixed double free in silc_server_command_leave in the file
3185 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Fixed the version checking in the server. Affected file is
3190 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3192 * Fixed the configuration data fetching when accepting new
3193 connections in the server. Affected file silcd/server.c.
3195 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Added `sender_entry' argument to the function
3198 silc_server_packet_relay_to_channel so that we can check
3199 whether some destination actually belongs to the same route
3200 the sender belongs (ie, we must not resend the packet to the
3201 sender). Affected file silcd/packet_send.[ch].
3203 * Added `servername' field to the SilcClientEntry in the server
3204 to hold the name of the server where client is from. Affected
3205 file is silcd/idlist.h.
3207 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Moved the channel message encrypting in the router betwen
3210 router connections from silc_server_channel_message to the
3211 silc_server_packet_relay_to_channel since we want to check
3212 whether we have anybody channel before encrypting anything.
3213 Affected files silcd/packet_[receive/send].c.
3215 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Fixed the [AdminConnection] server config section to support
3218 multiple entries. Affected file silcd/serverconfig.c.
3220 * Added support into the server to check the validity of the
3221 incoming connection before executing any KE or authentication
3224 * The connection configuration is now saved to the KE and
3225 connection auth protocol contexts and not fetched anymore in
3226 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3228 * The local hosts listenning address and port is also resolved
3229 now when starting the server. We want to have the socket object
3230 to include the real address and port for the listener. Added
3231 new function silc_net_check_local_by_sock into the files
3232 lib/silcutil/silcnet.[ch].
3234 * Fixed a broadcast bug in server -> do not broadcast if we
3237 * Fixed a routing bug. Do not route broadcast packets ever.
3238 Broadcast packets must be processed always and not routed since
3239 they may be destined to some other host than yourself and thus
3240 would get routed without no good reason. Affected file is
3243 * Added function silc_server_config_is_primary_route to check
3244 whether primary router connection has been configured (a router
3245 configuration that we are initiating). If there is not, we
3246 will assume that there is only two routers in the SILC network
3247 and we will use the incoming router connection as our primary
3248 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3250 * Changed the order of the broadcasting. Broadcast _after_ the
3251 packet has been processed not before. Affected file is
3254 * Fixed a [ClientConnection] parsing bug. The port was never
3255 parsed correctly thus resulting to port 0. Affected file
3256 silcd/serverconfig.c.
3258 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3259 argument and did not set the broadcast packet flag. Affected
3260 file silcd/packet_send.c. Fixed same bug in the function
3261 silc_server_send_notify as well.
3263 * If we receive NEW_ID packet for our own ID in the server, ignore
3266 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Removed the nickname from the Private Message Payload.
3271 Updated the code and the protocol specs.
3273 * Updated protocol specs for submitting to the IETF.
3275 * Tweaked the Random Number Generator a bit. Affected file
3276 lib/silccrypt/silcrng.c. Exported a new function
3277 silc_rng_[global]_add_noise which can be used to add more
3280 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Do not parse packets with different timeout when protocol
3283 is active -> may cause problem with rekey. Affected file
3286 * When server receives signoff notify it must not create
3287 new channel key if the client is on any channels since the
3288 sender of the signoff notify will create it.
3290 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added printing of error messages during SKE protocol from the
3293 failure packet sent by server during SKE. Affected file
3296 * Removed the client's failure_callback handling with timeout
3297 and handle it immediately when received.
3299 * The SKE library returned wrong type in SUCCESS and FAILURE
3300 packets. They must be 32 bit MSB not 16 bit MSB.
3302 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Ok, rewrote the logic of the re-key and now it seems to work.
3305 I tested it on high traffic with frequent re-keys without
3306 problems. Added hmac_receive (and renamed hmac to hmac_send)
3307 in SilcClientConnection in lib/silcclient/client.h and
3308 in SilcIDListData in silcd/idlist.h. Also, removed the
3309 SilcPacketParserContext's cipher and hmac fields as they are
3310 not needed anymore and actually caused some problems when
3311 the ciphers and hmac's changed underneath the packet parser.
3313 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * If re-key protocol is active then process the incoming packets
3316 synchronously since we must assure that icoming packets encrypted
3317 with the old key is processed before the new keys is set to
3318 use. This is true other packets than for REKEY packets.
3319 Affected file silcd/server.c. The same was done to client library
3320 as well, affected file lib/silcclient/client.c.
3322 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Fixed bug in client and server to accept the force send if
3325 the packet is send from silc_[server/client]_packet_process
3326 function. Otherwise the packets are never delivered, oops.
3328 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Disable force sending of packets when REKEY protocol is active.
3331 We must assure that no packet is sent directly when rekey is
3332 performed. All packets must be sent through packet queue.
3333 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3334 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3335 function is silc_[server/client]_packet_send_real to check
3338 * Replaced the SIM paths from example config files to
3339 /usr/local/modules. Also, make install creates now
3340 /usr/local/silc/logs directory to hold all the SILC server
3343 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Made the configure.in.pre work on Solaris. Patch by salo.
3347 * Made all ciphers compatible with non-x86 machines. Defined
3348 CBC mode macros into lib/silccrypt/ciphers_def.h.
3350 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Fixed the make install.
3354 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * When MAC computation fails the silc_packet_decrypt returned 0
3357 even though it was supposed to return -1. Fixed this. The
3358 affected file is lib/silccore/silcpacket.c.
3360 * Do not replace the config files in /etc/silc (in make install)
3361 if they already exist. Affected file ./Makefile.am.
3363 * Do not send re-key packets immediately but through packet queue.
3364 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3366 * Changed silc_net_check_host_by_sock to return FALSE if the
3367 IP/DNS could not be resolved. Though, it returns the IP address
3368 now even if it could not resolve it (but returns also FALSE).
3369 Affected file lib/silcutil/silcnet.[ch].
3371 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Added silc_pkcs_decode_identifier to decode the public key's
3374 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3375 Added also silc_pkcs_free_identifier. Added also new context
3376 SilcPublicKeyIdentifier.
3378 * Added -S option to the silc client. It is used to dump the
3379 contents of the specified public key file.
3381 * Changed the PKCS api to return the public key length when
3382 setting the public key.
3384 * Fixed a fatal bug in the public and private key file loading.
3385 Affected file lib/silccrypt/silcpkcs.c.
3387 * Execute the packet parsing for client with zero (0) timeout
3388 if the protocol is active. Affected file silcd/server.c.
3390 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * Made the key generation options to the silcd program. Added
3393 -C option, equivalent to client's option.
3395 * Added new [ServerKeys] config section to the server. It
3396 configures the server's public and private key.
3398 * Defined generic Public Key Payload into the protocol
3399 specification to send specific type of public keys and
3402 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3403 public key or certificate.
3405 * Implemented the GETKEY command to the server and to the
3406 client library and on user interface.
3408 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Made preliminary `make install' work.
3412 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Added SilcServerRekey context into silcd/idlist.h.
3416 * Added the PFS support as defined in the specification to the
3417 SKE protocol. Affected files lib/silcske/*.c.
3419 * Added `ske_group' field to the SilcServerRekey context to hold
3420 the number of the SKE group that is used with PFS in re-key.
3421 Affected file silcd/idlist.h.
3423 * Added PFS re-key support to the server. Affected file is
3426 * Added silc_protocol_cancel to cancel execution of the next
3427 state of the protocol. Affected file is
3428 lib/silccore/silcprotocol.[ch].
3430 * Added the re-key support with and without PFS to the client
3431 library. Re-key is performed once in an hour, by default.
3433 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3434 Added silc_client_rekey_callback and silc_client_rekey_final.
3435 Affected files are lib/silcclient/protocol.[ch] and
3436 lib/silcclient/client.[ch].
3438 * Removed the `hmac_key' and `hmac_key_len' fields from the
3439 SilcClientConnection structure; not needed. Affected file is
3440 lib/silcclient/client.h.
3444 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Do not ask whether user wants to use the negotiated private key
3447 for private messages, just use it. Affected file is
3448 silc/local_command.c.
3450 * Added `send_enc_key' and `enc_key_len' fields to the
3451 SilcIDListData structure since they are needed in the re-key
3452 phase. Affected file is silcd/idlist.[ch].
3454 * Implemented the simple re-key protocol into the server.
3455 Affected files silcd/server.c and silcd/protocol.[ch]. The
3456 re-key will be performed once in an hour, by default.
3458 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3459 Added silc_server_rekey, silc_server_rekey_callback and
3460 silc_server_rekey_final.
3462 * Removed Tunneled flag from the protocol. Updated the code
3463 and the specifications.
3465 * Adde `pfs' field to the SilcIDListData to indicate whether
3466 the PFS is to be performed in the re-key. Affected file is
3469 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3472 int64 of at least the xintXX size. If void * is less that 4
3473 bytes uint32 * will be used. Defined bool as boolean.
3475 * Changed _ALL_ unsigned long and unsigned int to uint32,
3476 unsgined short to uint16 in the source tree.
3478 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3479 not handle clients that has entry->data.registered == FALSE.
3480 They are not in the network anymore. Affected file is
3483 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Implemented the sending of the SERVER_SIGNOFF notify in the
3486 server. Affected file is silcd/server.c.
3488 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3489 Added also silc_notify_payload_encode_args into the
3490 lib/silccore/silcnotify.[ch].
3492 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3493 Affected file silcd/packet_receive.c.
3495 * Implemented the SERVER_SIGNOFF notify handling in the client
3496 library. Affected file lib/silcclient/client_notify.c. Also,
3497 implemnted the printing of the SERVER_SIGNOFF info to the
3498 application. Affected file silc/client_ops.c.
3500 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3501 if the deleting was successful. Affected file silcd/idlist.[ch].
3503 * Added support for public key authentication in the connection
3504 authentication protocol in the client library. Affected file
3505 lib/silcclient/protocol.c.
3507 * Changed the server's silc_idlist_get_clients_by_* interface
3508 to support already allocated array so that new entries may be
3509 added to pre-allocated array. Affected file silcd/idlist.[ch].
3510 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3511 and command replies.
3513 * All command reply functions in the server now calls the
3514 pending command callback even if error occured. This way the
3515 error will be delivered to the client as well. Affected files
3516 silcd/command.c and silcd/command_reply.c.
3518 * Fixed INFO command to return local server's info if no server
3519 was provided. Affected file lib/silcclient/command.c.
3521 * Removed RESTART command for good. Updated the code and the
3524 * Rewrote parts of the task system. It is a bit simpler now.
3525 Removed unsued task priorities. The affected files are
3526 lib/silcutil/silctask.[ch].
3528 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Moved the USERS printing from the library to the application.
3531 Affected files lib/silcclient/command.c and silc/client_ops.c.
3533 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Added channel key re-key support. The re-key is perfomed
3538 only by the router and is done once in an hour. Added `rekey'
3539 field to the SilcChannelEntry in the server. Affected files
3540 silcd/server.c and silcd/idlist.h.
3542 * Added silc_task_unregister_by_context into the file
3543 lib/silcutil/silctask.[ch].
3545 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added SILC_UMODE_GONE mode to indicate when the client is not
3548 present in the SILC network. Added also support to the local
3549 command AWAY that will set this mode. Added support of showing
3550 "xxx is gone" in WHOIS command. The USERS command shows the
3551 gone status as well.
3553 * Fixed setting server and router operator privileges in the
3554 server's UMODE command. Affected file silcd/command.c.
3556 * Merged the SKE KE1 and KE2 payloads into one payload. The
3557 new KE payload is equivalent to the old KE2 payload.
3559 Cleaned up the SKE Start Payload parsing. It now uses the
3560 simple buffer unformatting to do the parsing. A lot faster
3563 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3564 to the SKE that is used to indicate whether both of the SKE
3565 parties should perform authentication. By default only the
3566 responder performs authentication. By setting this flag also
3567 the initiator must do authentication. By default it is unset
3568 since in normal SKE case, client to server connection, only
3569 the responder should do authentication. When doing SKE between
3570 two clients both should perform authentication. Updated the
3571 code and the protocol specs.
3573 * A little fix to IDENTIFY command in the server. Search the
3574 client first by hash not nickname. Affected file is
3577 * Fixed the silc_client_close_connection to support closing
3578 the client to client connections wihtout deleting too much
3579 data. Affected file lib/silcclient/client.c.
3581 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3582 are received if protocol used to be active but is not anymore
3583 the application would crash due to NULL pointer dereference.
3584 Affected files silcd/server.c and lib/silcclient/client.c.
3586 * Added `hash' field to the SilcClientConnection to include
3587 the hash function negotiated in the SKE protocol.
3589 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3590 to set the channel founder authentication data. A client can
3591 claim the founder rights later by providing the authentication
3592 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3593 This way the channel founder can regain the channel founder
3594 privileges even it is left the channel. This works only on
3595 local server and the client must be connected to the same
3596 server to be able to regain the founder rights. Updated the
3597 protocol specs accordingly.
3599 Added support to the CMODE command in the client to set the
3600 founder auth data. Read the README to see how to set it.
3602 Added support to the CUMODE command to claim the founder
3603 rights. Read the README to see how to do it.
3605 Added support for the founder authentication to the Channel
3606 Entry in the server. Affected file silcd/idlist.h.
3608 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3609 server's CMODE command. Affected file silcd/command.c.
3611 * Added the following new functions into lib/silccore/silcauth.[ch]:
3612 silc_auth_get_method and silc_auth_get_data.
3614 * The server now saves the remote hosts public key to the
3615 SilcIDListData pointer. Affected file silcd/protocol.c.
3617 * The normal server now does not remove the channel entry from
3618 the cache if the founder authentication data is set. It used
3619 to remove it if the founder was the last one on the channel on
3620 the server and left the channel. The auth data is saved and
3621 if the channel is re-joined later the old entry is used with
3622 the old auth data. Affected files silcd/command_reply.c and
3625 * Removed the `pkcs' field from the SilcIDListData structure
3626 in the server; it is not used. Affected file silcd/idlist.h.
3628 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Fixed packet processing on slow links. Partial packets were
3631 never re-processed because the incoming data buffer was cleared
3632 by the application. Application must not directly clear the
3633 sock->inbuf, the packet processing routines handle it. Fixed
3634 this in client library and in server.
3636 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Fixed the WHOIS and IDENTIFY send reply function to really
3639 check whether to send list or just one entry. Affected file
3642 * Cleaned up the LEAVE command's channel key distribution. The
3643 affected file silcd/command.c.
3645 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3646 can enforce the channel mode as well. In that case the ID
3647 includes the ID of the server. The code now enforces the
3648 mode change if the router have different mode than the server.
3650 * The notify client operation with CMODE_CHANGE notify can now
3651 return NULL client_entry pointer if the CMODE was not changed
3652 by client. Application must check for this.
3654 * Added <Server ID> argument to INFO command to support server
3655 info fetching by Server ID.
3657 * Added silc_server_announce_get_channel_users to get assembled
3658 packets of channel users of the specified channel. Affected
3659 file silcd/server.[ch].
3661 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3662 was freed underneath the ID Cache.
3664 * Re-announce clients when the server received CHANNEL_CHANGE
3665 notify from the router. Affected file silcd/packet_send.c.
3667 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3670 crashed since it did not handle the fact that there is no cipher
3671 called "3" and didn't check the error condition. Now fixed.
3673 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3674 flag. It can be used to send message requests.
3676 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Implemented the RESTART command in the client.
3680 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3681 notice type messages. Added notice printing to the user
3684 * The channel keys are not re-generated if the channel's mode
3685 is PRIVKEY, ie private key on the channel exists. Affected
3686 files silcd/server.c and silcd/command.c.
3688 * Fixed a little bug in channel message delivery when channel
3689 private keys are set in the server. Affected file is
3690 silcd/packet_send.c.
3692 * Changed the setting on channel->on_channel = TRUE from the
3693 silc_client_save_channel_key to the JOIN command reply. The
3694 key payload is not received if the private channel key is set.
3695 Affected file lib/silcclient/command_reply.c and the
3696 lib/silcclient/client_channel.c.
3698 * When the CMODE_CHANGE notify is sent and the channel private
3699 key mode is removed the channel key must be re-generated in
3700 other cells as well. Added this support for the router in the
3701 silcd/packet_receive.c.
3703 * Added new local command NOTICE to send notice message on
3704 channel. Affected file silc/local_command.[ch].
3706 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added new local command ME to the client. It is used to send
3709 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3710 some action. Affected file silc/local_command.[ch].
3712 * Changed channel_message and private_message client operations
3713 to deliver the message flags to the application. Added also
3714 the `flags' arguments to the silc_client_send_channel_message
3715 and silc_client_send_private_message functions. Affected file
3718 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Redefined the Private Message Payload to support private message
3721 keys and to support the new private message flags. Updated
3722 the protocol specs. Flags makes it possible to have for example
3723 CTCP style messages.
3725 * Added new type SilcPrivateMessagePayload and defined an API
3726 for it in the lib/silcclient/silcprivate.[ch].
3728 * Tested private message private keys successfully. Tested the
3729 private message key set, unset and list commands with the new
3732 * Redefined the Channel Message Payload to include the channel
3733 message flags (equal with private message flags) to support
3734 for example CTCP style messages.
3736 * Defined some of the message (for channel and private message)
3737 flags. Updated the protocol specs and added the flags to the
3738 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3740 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Added SilcKeyAgreementStatus type to the key agreement routines
3743 to indicate the current status and error if one occured.
3744 The status types are defined in the lib/silcclient/silcapi.h.
3746 * Added new local command KEY that is used to set and unset private
3747 keys for channels, set and unset private keys for private messages
3748 with remote clients and to send key agreement requests and
3749 negotiate the key agreement protocol with remote client. The
3750 key agreement is supported only to negotiate private message keys,
3751 it currently cannot be used to negotiate private keys for channels,
3752 as it is not convenient for that purpose.
3754 * Fixed a minor pending callback setting bug in the function
3755 silc_client_get_client_by_id_resolve, now the function works.
3756 Affected file lib/silcclient/idlist.c.
3758 * Added function silc_net_get_local_port to get local bound
3759 port by socket. Added to lib/silcutil/silcnet.[ch].
3761 * Added `sockets' and `sockets_count' fields to the SilcClient
3762 object. They hold the sockets of the listenning sockets in
3763 the client. Listenning sockets may be for example the key
3764 agreement server. Affected file lib/silcclient/client.[ch].
3765 Added functions the silc_client_add_socket and the
3766 silc_client_del_socket. They are exported to the application
3769 * Added ~./silc/clientkeys to support other client's public keys.
3771 * Renamed verify_server_key client operation to verify_public_key
3772 and added one argument to indicate the type of the connection
3773 (server, client etc.).
3775 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Added silc_server_connection_auth_request to handle the
3778 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3779 silcd/packet_receive.[ch].
3781 * Added silc_server_send_connection_auth_request into the
3782 silcd/packet_send.c to send the connection auth request packet.
3784 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3787 * Fixed the public key authentication in responder side in the
3788 server. The `auth_data' pointer includes the SilcPublicKey
3789 not the path to the public key. Affected file silcd/protocol.c.
3791 * Implemented the public key authentication in the initiator side
3792 in the server. Affected file silcd/protocol.c.
3794 * Removed the [RedirectClient] config section from the server
3795 configuration. Is not needed and I don't want to implement it.
3797 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Cleaned up the CMODE command in the server. It now works
3800 correctly and supports all the modes defined in the protocol.
3801 Affected file is silcd/command.c.
3803 * Added `hmac_name' field to the SilcChannelEntry in the server
3804 to hold the default HMAC of the channel. It can be set when
3805 creating the channel (with JOIN command). Affected files
3808 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3809 type to indicate the change of the current cipher and hmac
3810 on the channel. Client can safely ignore the <cipher> argument
3811 (if it chooses to do so) since the CHANNEL_KEY packet will
3812 force the channel key change anyway. The <hmac> argument is
3813 important since the client is responsible of setting the new
3814 HMAC and the hmac key into use.
3816 * Fixed the CMODE command in the client library as well.
3818 * Tested CMODE command in router environment successfully.
3820 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Show the version of the remote client (or server) when connecting
3823 to the server. It is logged to the log file. Affected file
3824 is silcd/protocol.c.
3826 * Fixed the KILLED notify handling in the client library. The
3827 client must be removed from all channels when receiving the
3830 Also, do not remove the client entry when giving the KILL
3831 command but when the KILLED notify is received.
3833 * Removed silc_idlist_find_client_by_nickname from the server.
3834 Not needed anymore. Affected files silcd/idlist.[ch].
3836 * Implemented the CHANNEL_CHANGE notify type handling to the
3837 server. Affected file silcd/server.c.
3841 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Added silc_server_send_notify_invite to send the INVITE
3844 notify between routers.
3846 * Implemented the INVITE command correctly to the server.
3848 * Implemented the INVITE notify type handling in the server.
3850 * Implemented the INVITE command to the client library and on the
3853 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3855 * Added function silc_server_get_client_resolve to find the
3856 client entry by ID from all ID lists and then resolve it
3857 (using WHOIS) if it cannot be found. Affected file is
3860 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Implemented the BAN command to the client library.
3864 * The JOIN command in the server now checks the invite list
3867 * Changed the silc_command_reply_payload_encode_va and the
3868 silc_command_payload_encode_va to support that if argument is
3869 NULL it ignores and checks the next argument. Affected file
3870 lib/silccore/silccommand.c.
3872 * Added silc_server_send_notify_ban to send the BAN notify
3873 type between routers.
3875 * Chaned the silc_notify_payload_encode to support that if
3876 argument is NULL it ignores and checks the next argument.
3877 Affected file lib/silccore/silcnotify.c.
3879 * Tested ban lists in router environment successfully.
3881 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Implemented BAN command to the server, in silcd/command.[ch].
3885 * Removed the BAN and INVITE_LIST modes from the CMODE command
3888 * Added function silc_string_match to regex match two strings.
3889 Affected files lib/silcutil/silcutil.[ch].
3891 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Redefined parts of the SilcChannelEntry in the server to support
3894 the new ban and invite lists.
3896 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Redefined the INVITE command. The same command can be used to
3899 invite individuals to the channel but also to manage the invite
3900 list of the channel (to add to and remove from the invite list).
3901 Updated the protocol specs.
3903 * Added new command SILC_COMMAND_BAN that can be used to manage
3904 the ban list of the channel. Updated the protocol specs.
3906 * Removed the channel modes: the SILC_CMODE_BAN and the
3907 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3908 in the CMODE command. The equivalent features are now available
3909 using INVITE and BAN commands. Updated the protocol specs.
3911 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3912 in the network about change in the current ban list. The notify
3913 type is not used by the client.
3915 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3916 support the invite lists.
3918 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Added new function silc_string_regexify that converts string
3921 including wildcard characters into regex string that can
3922 be used by the GNU regex library. Added into the file
3923 lib/silcutil/silcutil.[ch].
3925 Added silc_string_regex_combine to combine to regex strings
3926 into one so that they can be used as one regex string by
3927 the GNU regex library. Added into the file
3928 lib/silcutil/silcutil.[ch].
3930 Added silc_string_regex_match to match two strings. It returns
3931 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3933 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Imported GNU regex to the soruce tree into lib/contrib.
3936 Fixed some compiler warning from the regex.c.
3938 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Fixed MOTD command in the server to work in router environment.
3942 * Fixed the MOTD command in the client library to support
3943 the server argument in the command.
3945 * Added `nickname_len' argument to the silc_idlist_add_client
3946 in the server, as the `nickname' argument may be binary data
3949 * Added silc_idlist_get_channels to return all channels from
3952 * Implemented LIST command to the server. Affected file is
3955 * Implemented the LIST command to the client library and on the
3958 * Added [<user count>] argument to the LIST command reply.
3959 With private channels the user count is not shown.
3961 * Updated TODO and README.
3963 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * The client entry's data.registered must be TRUE even with
3966 global client entry on global client list. The data.registered
3967 is used to check whether the client is anymore in the network,
3968 for example with WHOWAS command so it must be valid.
3970 * Fixed the WHOWAS command in the server. It now actually works
3971 in router environment. Added function into silcd/command_reply.c
3972 silc_server_command_reply_whowas_save.
3974 * Added silc_idlist_purge function to the silcd/idlist.c
3975 to periodically purge the ID Cache.
3977 * Fixed INFO command in the server. It works now in router
3978 environment. Added <server name> argument to the INFO command
3979 reply. Updated the protocol specs.
3981 * Fixed minor bug in silc_idcache_purge to not purge if the
3982 expire value is zero.
3984 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3985 they were buggy because of the WHOWAS information.
3987 * Fixed local command MSG to handle the async resolving of
3988 the remote client properly. It used to fail the first MSG.
3989 Affected file silc/local_command.c.
3991 * Added `data_len' field to SilcIDCache context.
3993 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Update TODO. Todo in commands in the server.
3997 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4000 used by routers as broadcast packet to inform other routers
4001 about the changed user mode.
4003 Implemented the notify handling in the server. Affected file is
4004 silcd/packet_receive.c. Added the function
4005 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4007 * Added new generic Channel Payload and deprecated the New Channel
4008 Payload. The New Channel Payload is now the generic Channel
4011 * Added new argument `mode' to the silc_server_send_new_channel
4012 as it is required in the Channel Payload now.
4014 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4015 and created a new and real SilChannelPayload to represent the
4016 new generic Channel Payload. Implemented the encode/decode
4017 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4019 * Added silc_server_get_client_channel_list to return the list
4020 of channels the client has joined for WHOIS command reply.
4021 Affected file silcd/server.[ch].
4023 * Implemented the channel list sending in the WHOIS command reply
4024 in server and in the client.
4026 Implemented the channel list displaying on the user interface
4027 as well. Affected file silc/client_ops.c.
4029 * Added silc_channel_payload_parse_list to parse list of Channel
4030 Payloads. It returns SilcDList list of SilcChannelPayloads.
4031 Client for example can use this function to parse the list of
4032 channels it receives in the WHOIS command reply. The caller
4033 must free the list by calling silc_channel_payload_list_free.
4034 Affected files lib/silccore/silcchannel.[ch].
4036 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Added one new argument <user mode> to the WHOIS command reply
4039 to return the mode of the user in SILC. Updated the protocol
4042 Implemented it to the server and client.
4044 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Fixed the mode printing on the user interface on joining.
4047 Affected file silc/client_ops.c.
4049 * Implemented the UMODE command and user modes in general to the
4050 client library and to the user interface.
4052 * Implemented the UMODE command to the server.
4054 * The server now sends UNKNOWN_COMMAND error status if client sends
4055 unknown command. Affected file silcd/command.c.
4057 * All server commands now handle the command identifier the right
4058 way when sending the command reply to the client. The client can
4059 use to identify the command replies with the identifier.
4061 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Added silc_server_get_client_route to resolve the route to
4064 the client indicated by the client ID. Affected file is
4067 * Added silc_server_relay_packet as general function to relay
4068 packet to arbitrary destination. This deprecates functions
4069 like _send_private_message_key, _relay_notify etc. Affected
4070 file is silcd/packet_send.[ch].
4072 Removed silc_server_send_key_agreement,
4073 silc_server_send_private_message_key and
4074 silc_server_packet_relay_notify functions from the file
4075 silcd/packet_send.[ch].
4079 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4080 server. Affected file silcd/packet_receive.[ch].
4082 * Implemented the KILL command to the client. Implemented the
4083 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4084 Affected files lib/silcclient/command[_reply].c and
4085 lib/silcclient/client_notify.c. Implemented the KILL notify
4086 printing in the user inteface.
4088 * Fixed a lot silc_parse_nick memory leaks from the client
4089 library in the file lib/silcclient/command.c.
4091 * Changed the silc_server_send_notify_on_channels's `sender'
4092 argument from SilcSocketConnection to SilcClientEntry to
4093 check the sender as entry and not as connection object and not
4094 to send to the client provided as argument. The affected file
4095 is silcd/packet_send.[ch].
4097 * The notify packets that are destined directly to the client used
4098 to not to be processed by the server. Now changed that and the
4099 server processes all notify packets. After relaying the packet
4100 to the client the notify packet is processed in the server.
4102 * The silc_server_free_client_data now checks whether there is
4103 pending outgoing traffic for the client and purges the data to
4104 the network before removing the client entry.
4106 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4109 an client is killed from the SILC Network. Updated the protocol
4112 Added new function silc_server_send_notify_killed to the
4113 silcd/packet_send.[ch].
4115 * Added function silc_server_packet_relay_notify to relay notify
4116 packets that are destined directly to a client. In this case
4117 the server does not process the notify packets but merely relays
4118 it to the client. Affected file silcd/packet_send.[ch].
4120 Added also silc_server_packet_process_relay_notify to check
4121 whereto relay the notify. Affected file is
4122 silcd/packet_receive.[ch].
4124 * Implemented the KILL command to the server.
4128 * Added the backup schema desgined last fall to the protocol
4129 specs for everyone to see. The specification is in the
4130 *-spec-xx.txt draft and the packet type definitions for the
4131 backup routers is in *-pp-xx.txt draft. Thusly, added also
4132 new packet type SILC_PACKET_CELL_ROUTERS.
4134 * A big security problem in the implementation discovered. The
4135 signoff of an client did not cause new channel key generation
4136 which it of course should've done. The channel keys must be
4137 always re-generated when client leaves (or signoffs) the channel.
4138 The silc_server_remove_from_channels funtion now handles
4139 the channel key re-generation.
4141 * Added `sender' argument to the silc_server_send_notify_on_channels
4142 to not to send the client provided as argument. Affected file
4143 silcd/packet_send.[ch].
4145 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Implemented OPER and SILCOPER commands into the server and
4150 * Added silc_auth_verify and silc_auth_verify_data to verify
4151 the authentication directly from the authentication payload.
4152 It supports verifying both passphrase and public key based
4153 authentication. Affected file lib/silccore/silcauth.[ch].
4155 * Added `hash' field to the SilcIDListData structure. It is the
4156 hash negotiated in the SKE protocol. Affected file is
4159 * Slight redesigning of the SilcAuthPayload handling routines.
4160 Do not send SilcPKCS but SilcPublicKey as argument.
4162 * Implemented the public key authentication support to the
4163 serverconfig. The public key is loaded from the provided path
4164 and saved as authentication data to void * pointer. Thus,
4165 changed the unsigned char *auth_data to void *auth_data;
4167 * Fixed SHUTDOWN command to send the reply before the server
4168 is shutdown. :) Affected file silcd/command.c.
4170 * Fixed fatal bug in CONNECT command. The hostname was invalid
4171 memory and server crashed. Affected file silcd/command.c.
4173 * Fixed fatal bug in CLOSE command. The server_entry became
4174 invalid but was referenced later in the command. Affected file
4177 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Fixed fatal bug in failure packet handling. Server ignored
4180 the failure and thus crashed when it came.
4184 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4187 that the command may be executed only once in (about) 2 seconds.
4188 The old SILC_CF_LAG flag is same but allows command bursts up
4189 to five before limiting.
4191 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4192 server code. Various commands now includes the CF_LAG_STRICT
4193 flag to disallow any kind of miss-use of the command.
4195 * Fixed the silc_buffer_unformat to not to allocate any data
4196 if the length of the data is zero. It used to allocate the
4197 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4199 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Changed the format of AdminConnection configuration section
4202 in the server. Added username of the admin to the format.
4203 Affected files silcd/serverconfig.[ch].
4205 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4206 to return admin configuration data by host, username and/or
4209 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Implemented WHOWAS command to the server. Added the functions:
4213 silc_server_command_whowas_parse,
4214 silc_server_command_whowas_send_reply,
4215 silc_server_command_whowas_from_client and
4216 silc_server_command_whowas_from_server
4218 * Added <Client ID> argument to the WHOWAS command reply. Updated
4219 the protocol specs accordingly.
4221 * Implemented WHOWAS command and command_reply to the client
4224 Implemented the WHOWAS printing on the user interface.
4226 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Added new argument to the WHOWAS command reply, the real name.
4229 It is an optional argument. Updated the protocol specs.
4231 * Added SilcIDCacheDestructor callback that is registered when
4232 the SilcIDCache is allocated. The callback is called when
4233 an cache entry in the ID Cache expires, or is purged from the
4234 cache. Added into lib/silccore/idcache.[ch].
4236 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4237 to destruct the client entries when the cache entry expires.
4238 Other ID Cache's in server and in the client library ignores
4241 * If the ID Cache entry's `expire' field is zero then the entry
4242 never expires. Added boolean `expire' argument to the
4243 silc_idcache_add function in the lib/silccore/idcache.[ch].
4244 If it is TRUE the default expiry value is used.
4246 * Added silc_server_free_client_data_timeout that is registered
4247 when client disconnects. By default for 5 minutes we preserve
4248 the client entry for history - for WHOWAS command.
4250 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Added support to the server to enforce that commands are not
4253 executed more than once in 2 seconds. If server receives
4254 commands from client more frequently, timeout is registered
4255 to process the commands. Affected file silcd/command.c.
4256 Added new function silc_server_command_process_timeout.
4258 * Changed NICK_NOTIFY handling in client library to check that
4259 if the client's nickname was changed, so there is no need to
4260 resolve anything from the server.
4262 * Removed error printing from the WHOIS and IDENTIFY commands.
4263 If error occurs then it is ignored silently in the client library.
4264 The application, however, may map the received error to
4265 human readable error string. The application currently maps
4266 the NO_SUCH_NICKNAME error to string.
4268 * Made the command status message public to the application. Moved
4269 them from lib/silcclient/command_reply.c to
4270 lib/silcclient/command_reply.h. The application can map the
4271 received command status to the string with the
4272 silc_client_command_status_message function.
4274 * Added check to the server to check that client's ID is same
4275 as the Source ID in the packet the client sent. They must
4278 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Added dist-bzip hook to the Makefile.am to make bzip2
4281 compressed distributions.
4283 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Server now enforces the maximum length for the nickname and
4286 the channel as protocol specification dictates. 128 bytes for
4287 nickname and 256 bytes for channel name.
4289 * Moved the WHOIS printing to the application. The client libary
4290 does not print out the WHOIS information anymore, the application
4291 must do it. Renamed silc_client_command_reply_whois_print to
4292 the silc_client_command_reply_whois_save.
4294 The client's idle time is also sent to the application now, and
4295 the idle is shown on screen.
4297 * Added silc_client_command_reply_identify_save to save the
4298 received IDENTIFY entries.
4300 * Do not check for channel private keys in message sending and
4301 reception if the channel does not have the PRIVKEY mode set.
4302 Affected file lib/silclient/client_channel.c.
4304 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4307 just surfaced after chaning the JOIN procedure.
4309 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Added silc_client_get_clients_by_list to get client entries
4312 from Client ID list, that is returned for example by JOIN
4313 and USERS command replies. The application should use this
4314 function for example when JOIN command reply is received to
4315 resolve the clients already on the channel (library does not
4316 do that anymore as USERS command reply is not used in the JOIN
4317 procedure anymore). Affected files lib/silcclient/silcapi.h and
4318 lib/silcclient/idlist.c.
4320 * JOIN command reply and USERS command reply returns now SilcBuffer
4321 pointers instead of unsigned char pointers when returning
4322 the client list and mode list.
4324 * Added <Client ID> argument to the JOIN command reply, mainly
4325 for the server to identify for which client the command was
4326 originally sent. Updated protocol specs accordingly.
4328 * Added SilcDlist private_key pointer to the SilcChannelEntry
4329 in the client to support the channel private keys. Affected
4330 file is lib/silcclient/idlist.h.
4332 * Added SilcChannelPrivateKey argument to the function
4333 silc_client_send_channel_message so that application can choose
4334 to use specific private ke if it wants to. If it is not provided,
4335 the normal channel key is used, unless private keys are set.
4336 In this case the first (key that was added first) is used
4337 as the encryption key.
4339 * Implemented the support for channel private key handling.
4340 Implemented the following functions:
4342 silc_client_add_channel_private_key,
4343 silc_client_del_channel_private_keys,
4344 silc_client_del_channel_private_key,
4345 silc_client_list_channel_private_keys and
4346 silc_client_free_channel_private_keys
4348 Affected file lib/silcclient/client_channel.c.
4350 * Added the support for the private keys in the channel message
4351 sending and encryption and in the message reception and
4352 decryption. Affected funtions are
4353 silc_client_send_channel_message and silc_client_channel_message.
4355 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Added SKE's key verify callback to the client library's
4358 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4360 * Removed the statement that server (or router) must send USERS
4361 command reply when joining to the channel so that the client
4362 knows who are on the channel. Instead, the client list and
4363 client's mode list is now sent in the JOIN command reply to the
4364 client who joined channel. This is better solution.
4366 * Added function silc_server_get_users_on_channel and function
4367 silc_server_save_users_on_channel to the silcd/server.[ch].
4369 * Removed function silc_server_command_send_users from the
4372 * Do not show topic on the client library anymore. The topic is
4373 sent in the command reply notify to the application and the
4374 application must show the topic now.
4376 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Added client searching by nickname hash into the IDENTIFY and
4379 WHOIS commands in the server as they were clearly missing from
4380 them. Affected file is silcd/command.c.
4382 * Fixed a bug in private message receiving in the client library.
4383 The remote ID was freed and it wasn't supposed, now it is
4386 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Minor fix to the channel payload; allocate the data area, as it
4389 needs to be of specific length.
4391 * If the key agreement port is zero then the operating
4392 system will define the bound port. Affected files are
4393 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4395 * Added new function silc_channel_payload_decrypt into the file
4396 lib/silccore/silcchannel.[ch].
4398 * Moved the channel message etc, check from silc_packet_decrypt
4399 to applications. The library calls now a generic
4400 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4401 when the packet is either normal or special. This was done to
4402 allow more wide range of checking that was not allowed when
4403 the code was in library. Now applications can do virtually any
4404 checks to the packet and return to the library the decision how
4405 the packet should be processed. Affected files are
4406 lib/silccore/silcpacket.[ch].
4408 Added silc_server_packet_decrypt_check to the server and
4409 silc_client_packet_decrypt_check to the client library.
4411 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4412 to send with specified source and destination information.
4414 * Channel message delivery between routers was broken after the
4415 channel key distribution was fixed earlier. The channel key
4416 was used be to distributed to other routers as well which is not
4417 allowed by the protocol. Now this is fixed and channel keys
4418 really are cell specific and the channel message delivery between
4419 routers comply with the protocol specification.
4421 * Fixed various commands in server to check also the global list
4422 for the channel entry and not just the local list. The affected
4423 file silcd/command.c.
4425 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added assert()s to buffer formatting and unformatting routines
4428 to assert (if --enable-debug) when error occurs. Affected
4429 file: lib/silcutil/silcbuffmt.c.
4431 * Changed to auto-reconnect to check whether the remote host is
4432 router and register the re-connect timeout if it is. It used
4433 to check that whether we are normal server, but router must do
4434 auto-reconnect with another router as well. Affected file
4437 * Removed the [<key len>] option from CMODE command as the cipher
4438 name decides the key length, nowadays. See the defined ciphers
4439 from the protocol specification.
4441 * Added [<hmac>] option to the CMODE command to define the HMAC
4442 for the channel. Added SILC_CMODE_HMAC channel mode.
4444 * Added [<hmac>] option for the JOIN command so that user can
4445 select which HMAC is used to compute the MACs of the channel
4448 * Added Hmac field to the Channel Message Payload. The integrity
4449 of plaintext channel messages are now protected by computing
4450 MAC of the message and attaching the MAC to the payload. The
4451 MAC is encrypted. Now, it is clear that this causes some
4452 overhead to the size of the packet but rationale for this is that
4453 now the receiver can verify whether the channel message decrypted
4454 correctly and also when private keys are set for the channel the
4455 receiver can decrypt the packet with several keys and check from
4456 the MAC which key decrypted the message correctly.
4458 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4459 lib/silccrypt/silccipher.[ch].
4461 * Added silc_hash_len to return the digest length into the
4462 lib/silcrypt/silchash.[ch].
4464 * Rewrote parts of Silc Channel Payload interface in the
4465 lib/silccore/silcchannel.[ch]. The encode function now also
4466 encrypts the packet and parse function decrypts it.
4468 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Fixed a minor formatting bug in the SKE's key material processing.
4471 It actually might have processed the keys wrong way resulting
4474 * Redefined the mandatory HMAC algorithms and added new algorithms.
4475 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4476 and hmac-md5 truncated to 96 bits. The mandatory is now
4477 hmac-sha1-96. Rest are optional (including the one that used
4478 to be mandatory). Rationale for this is that the truncated HMAC
4479 length is sufficient from security point of view and can actually
4480 make the attack against the HMAC harder. Also, the truncated
4481 HMAC causes less overhead to the packets. See the RFC2104 for
4484 * Added new [hmac] configuration section. The SKE used to use
4485 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4486 is of course wrong. The official names that must be proposed in
4487 the SKE are the ones defined in the protocol specification
4488 (hmac-sha1-96 for example). The user can configure any hmac
4489 using any hash function configured in the [hash] section. At
4490 least, the mandatory must be configured.
4492 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4494 * Added HMAC list to the SKE proposal list. It has now both
4495 hash algorithm list and HMAC list. This makes the protocol
4496 incompatible with previous versions. The SKE now seems to work
4497 the way it is supposed to work, for the first time actually.
4499 * Defined plain Hash algorithms to the protocol specification.
4502 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Implemented support for key agreement packets into the server.
4505 Added functions silc_server_key_agreement and
4506 silc_server_send_key_agreement. Other than these functions,
4507 server has nothing to do with this packet.
4509 * Added support for private message key packets into the server.
4510 Added functions silc_server_private_message_key and
4511 silc_server_send_private_message_key.
4515 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4516 called in the protocol's final callback instead in the END
4517 protocol state. This makes a little more sense and in the same
4518 time in client we can use the same protocol routines for normal
4519 key exchange and to key agreement packet handling as well.
4521 * Added to both client's and server's KE protocol context the
4522 SilcSKEKeyMaterial pointer to save the key material. We will
4523 bring the key material to the protocol's final callback by doing
4524 this. The final callback must free the key material.
4526 * Added SKE's packet_send callback into client's KE protocol
4527 context so that the caller can choose what packet sending function
4528 is used. This way we can use different packet sending when
4529 doing normal SKE when doing key agreement packet handling (in
4530 the key agreement packet handling we do not want to encrypt
4533 * Implemented the responder side of the key agreement routines
4534 in the client. The client can now bind to specified port and
4535 accept incoming key negotiation. The key material is passed
4536 to the application after the protocol is over.
4538 * Implemented the processing of incoming Key Agreement packet
4539 in the client. Added function silc_client_key_agreement to
4542 * Implemented the intiator side of the key agreement routines
4543 in the client. The client can now initiate key agreement with
4544 another remote client. The key material is passed to the
4545 application after the protocol is over.
4547 * Created client_keyagr.c to include all the key agreement
4550 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4551 SILC_TASK_CALLBACK except that it is not static.
4553 * Created client_notify.c and moved the Notify packet handling
4554 from the client.[ch] into that file.
4556 * Created client_prvmsg.c and moved all private message and
4557 private message key routines from the client.[ch] into that file.
4559 * Create client_channel.c and moved all channel message and
4560 channel private key routines from the client.[ch] into that file.
4562 * Changed silc_client_get_client_by_id_resolve to resolve with
4563 WHOIS command instead of IDENTIFY command, in the file
4564 lib/silclient/idlist.c.
4566 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Implemented the SKE's responder side to the Client library.
4570 * When FAILURE is received to the protocol do not trust it
4571 blindly. Register a timeout to wait whether the remote closes
4572 the connection as it should do it, only after that process the
4573 actual failure. This was changed to both client and server.
4575 * Added client_internal.h to include some of the structures
4576 there instead of client.h in lib/silcclient/.
4578 * Added function silc_task_unregister_by_callback to unregister
4579 timeouts by the callback function.
4581 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Some "Incomplete WHOIS info" errors has been appearing on the
4584 log files. Took away the entry->userinfo check from WHOIS
4585 reply sending. The entry->userinfo is now " " if client did not
4586 provide one. I thought this was fixed earlier but something
4587 is wrong still. Let's see if the error still appears.
4589 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Fixed a minor bug in the login when the channel key is
4592 re-generated in the server. It used to generate the key in
4593 wrong order and thus caused problems in the channel traffic.
4595 * Fixed a minor bug in channel key distsribution after
4596 KICK command. The key was not sent to the router even though
4599 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Added silc_ske_process_key_material_data as generic routine
4602 to process any key material as the SILC protocol dictates. The
4603 function is used by the actual SKE library but can be used by
4604 applications as well. This relates to the private message keys
4605 and the channel private keys since they must be processed the
4606 same way the normal SILC session keys. The protocol dictates
4607 this. Affected files: lib/silcske/silcske.[ch].
4609 Added also silc_ske_free_key_material to free the
4610 SilcSKEKeyMaterial structure.
4612 * Defined silc_cipher_set_key function to set the key for
4613 cipher without using the object's method function. The affected
4614 files: lib/silccrypt/silccipher.[ch].
4616 * Implemented silc silc_client_add_private_message_key,
4617 silc_client_add_private_message_key_ske,
4618 silc_client_del_private_message_key,
4619 silc_client_list_private_message_keys and
4620 silc_client_free_private_message_keys functions in the
4623 Added functions silc_client_send_private_message_key to send
4624 the Private Message Key payload and silc_client_private_message_key
4625 to handle incoming Private Message Key payload.
4627 * Added Cipher field to the Private Message Key payload to set
4628 the cipher to be used. If ignored, the default cipher defined
4629 in the SILC protocol (aes-256-cbc) is used.
4631 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Removed lib/silcclient/ops.h file.
4635 Redefined parts of the SILC Client Library API. Created new
4636 file silcapi.h that deprecates the ops.h file and defines the
4637 published Client Library API. Defined also private message key
4638 API and channel private key API into the file.
4640 This is the file that the application must include from the
4641 SILC Client Library. Other files need not be included by
4642 the application anymore.
4644 * Added new key_agreement client operation callback and also
4645 defined the Key Agreement library API for the application.
4647 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4650 is used by clients to request key negotiation between another
4651 client in the SILC network. If the negotiation is started it
4652 is performed using the SKE protocol. The result of the
4653 negotiation, the secret key material, can be used for example
4654 as private message key.
4656 Implemented the Key Agreement payload into the files
4657 lib/silccore/silauth.[ch].
4659 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Redefined ciphers for the SILC protocol. Added some new ciphers
4662 and defined the key lengths for the algorithms. Changed the
4663 code accordingly. The default key length is now 256 bits.
4665 * Fixed SKE key distribution function silc_ske_process_key_material
4666 when the key length is more than 128 bits. The default key
4667 length in SILC is now 256 bits.
4669 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4670 to indicate unsupported algorithm.
4672 * Renamed rijndael.c to aes.c and all functions as well.
4674 * Fixed a long standing channel key setting bug in client library.
4675 Weird that it has never surfaced before.
4677 * Fixed bug in channel deletion. If the entire channel is removed
4678 then it must also delete the references of the channel entry
4679 from the client's channel list as the client's channel entry and
4680 the channel's client entry share same memory.
4682 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Implemented CONNECT and SHUTDOWN commands in the client.
4686 * Implemented CLOSE command to the client.
4688 * Added the function silc_idlist_find_server_by_name into the
4689 files silcd/idlist.[ch].
4691 Added the function silc_idlist_find_server_by_conn into the
4692 files silcd/idlist.[ch].
4694 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * DIE command was renamed to SHUTDOWN. Updated the both code
4699 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4700 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4702 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4705 * Added function silc_server_create_connection function to create
4706 connection to remote router. My server implementation actually
4707 does not allow router to connect to normal server (it expects
4708 that normal server always initiates the connection to the router)
4709 so the CONNECT command is only good for connecting to another
4712 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4715 or some other client was kicked from the channel.
4717 Implemented the handling of the notify type to both client
4720 Implemented silc_server_send_notify_kicked to send the KICKED
4721 notify. It is used to send it to the server's primary router.
4723 * Implemented the KICK command into server and client.
4725 * Added `query' argument to the silc_idlist_get_client function
4726 to indicate whether to query the client from server or not if
4729 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4730 to indicate that the client is not channel founder.
4734 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Removed the rng context from SilcPacketContext structure and
4737 changed that the packet routine uses the Global RNG API.
4739 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Added support for quit message that client can "leave" on the
4742 channel when it quits the SILC. It is ditributed inside the
4743 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4745 Added silc_server_free_client_data that will take the
4746 signoff message as argument.
4748 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4750 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Updated parts of the protocol specification to keep it up
4755 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4758 payloads in one packet.
4760 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4761 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4762 use now the new List flag.
4764 * Also deprecated the following packet types: REPLACE_ID,
4765 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4767 * Added list support for Notify packet in server.
4769 * Added silc_server_send_notify_channel_change to send the
4770 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4771 the silc_server_send_replace_id.
4773 * Added silc_server_send_notify_nick_change to send the
4774 NICK_CHANGE notify type. Deprecates the function
4775 silc_server_send_replace_id.
4777 * Added silc_server_send_notify_join to send the JOIN notify type.
4778 Deprecates the function silc_server_send_new_channel_user.
4780 * Added silc_server_send_notify_leave to send LEAVE notify type.
4781 Deprecates the function silc_server_send_remove_channel_user.
4783 * Added silc_server_send_notify_cmode and
4784 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4785 types. Deprecates the silc_server_send_set_mode function.
4787 * Added SERVER_SIGNOFF notify type to indicate that server has
4788 quit. This means that all clients on the channel from that
4789 server will drop. This can be also used when netsplit happens.
4791 Deprecated REMOVE_ID packet type since it is not needed anymore
4794 Added silc_server_send_notify_server_signoff to send the
4795 SERVER_SIGNOFF notify type. Deprecates the function
4796 silc_server_send_remove_id.
4798 Added also silc_server_send_notify_signoff to send the
4799 SIGNOFF notify type.
4801 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4802 SILC protocol from this day on. Changed the protocol
4803 specification as well.
4805 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4806 notify type. It is used between routers to notify about
4807 topic changes on a channel.
4809 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4812 * Partly updated the protocol specification to comply with the
4813 changes now made. It is still though a bit outdated.
4815 * The JOIN notify type now takes one extra argument <Channel ID>.
4816 The packet used to be destined to the channel but now the
4817 JOIN type may be sent as list thus it is impossible to
4818 destine it to any specific channel. By adding this argument
4819 it is again possible.
4821 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Added CREDITS file. The CHANGES and CREDITS file will appear
4824 in the distribution as well.
4826 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4829 types in the server's silcd/packet_receive.c.
4831 * Implemented CMODE and CUMODE to work in router environment.
4833 * Fixed minor encoding and decoding buglet from the
4834 lib/silccore/silcmode.c.
4836 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4839 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4841 * Changed all SilcConfigServer* and silc_config_server* to
4842 SilcServerConfig* and silc_server_config*, respectively.
4845 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Associated the ID (client or server ID) to the Authentication
4848 Payload to avoid any possibility of forging. Updated the
4849 protocol specification and the code accordingly.
4851 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * The RSA key length is now save to the RsaKey context in the
4854 key generation process in lib/silccrypt/rsa.c. The key length
4855 is now used to figure out the maximum size of the block allowed
4856 to be encrypted/signed.
4858 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4859 is equivalent to the silc_mp_mp2bin but does not allocate any
4862 * Changed silc_mp_mp2bin API to take length argument. If it is
4863 non-zero then the buffer is allocated that large. If zero, then
4864 the size is approximated using silc_mp_sizeinbase, which however
4867 * Created Global RNG API which is global RNG that application can
4868 initialize. After initializing, any routine anywhere in the
4869 code (including library) can use RNG without allocating a new
4870 RNG object. This was done to allow this sort of use of the
4871 RNG in code that has no chance to allocate RNG object. All
4872 applications currently allocate this and many routines in the
4873 library use this. Affected file lib/silccrypt/silcrng.[ch].
4875 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4876 it to use the Global RNG API.
4878 * Defined Authentication Payload into protocol specification that
4879 is used during SILC session to authenticate entities. It is
4880 used for example by client to authenticate itself to the server
4881 to obtain server operator privileges.
4883 Implemented this payload into the lib/silccore/silcauth.[ch].
4884 Implemented also routines for public key based authentication
4885 as the new protocol specification dictates.
4887 Moved definitions of different authentication methods from
4888 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4890 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4891 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4892 silc_pkcs_verify_with_hash functions into the file
4893 lib/silccrypt/silcpkcs.[ch].
4895 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * The client entry's userinfo pointer must be always valid.
4898 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4899 will fail since it requires the userinfo. Now, the userinfo
4900 is allocated as "" if actual userinfo does not exist. Actually,
4901 it must exist and it is totally Ok to drop client connections
4902 that does not announce the userinfo. However, we will make
4903 this workaround for now.
4905 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4906 to return the remote port by socket.
4908 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4911 SILC_SERVER_PENDING_EXEC and added an new macro
4912 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4913 data or when error occurs while processing the pending command.
4915 Added new argument `destructor' into silc_server_command_pending
4916 and to the SilcServerCommandPending object. This destructor is
4917 now called after calling the pending callback or if error occurs
4918 immediately. If error occurs the actual pending callback won't
4919 be called at all - only the destructor. The destructor may be
4920 NULL if destructor is not needed.
4922 All this applies for client library code as well. Similar
4923 changes were made there as well for the pending commands.
4925 In the client, the application must now allocate the
4926 SilcClientCommandContext with the silc_client_command_alloc
4929 * Added reference counter to the SilcServerCommandContext. Added
4930 function silc_server_command_alloc and silc_server_command_dup
4933 Same type of functions added to the client library for the same
4936 * Removed the cmd_ident from IDListData away since it is now
4937 global for all connections. It is the command identifier used
4938 in command sending and with pending commands. The affected file
4941 * Added reference counter to the SilcSocketConnection objecet to
4942 indicate the usage count of the object. The object won't be
4943 freed untill the reference counter hits zero. Currently only
4944 server uses this, and client ignores it. The client must be
4945 set to use this too later. The affected files are
4946 lib/silccore/silcsockconn.[ch]. Added also the function
4947 silc_socket_dup to increase the reference counter.
4949 This was mainly added because it is possible that the socket
4950 is removed underneath of pending command or other async
4951 operation. Now it won't be free'd and proper DISCONNECTING
4952 flags, etc. can be set to avoid sending data to connection that
4953 is not valid anymore.
4955 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4956 the connection. After that it sets SILC_SET_DISCONNECTED.
4957 It is, however, possible that the socket data is not still freed.
4958 The silc_server_packet_process now checks that data is not
4959 read or written to connection that is DISCONNECTED. The socket
4960 get's freed when the reference counter hits zero.
4962 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Changed the client operation API: channel_message operation's
4965 `sender' is now the client entry of the sender, not the nickname
4966 and the `channel' is the channel entry, not the channel name.
4968 In the private_message operation the `sender' is now also the
4969 client entry of the sender not the nickname.
4971 Affected file is lib/silcclient/ops.h and all applications
4972 using the client operations.
4974 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Moved the calling of ops->connect() from connect_to_server_final
4977 into receive_new_id functin since that is the point when the
4978 client is actually allowed to send traffic to network. The
4979 affected file is lib/silcclient/client.c.
4981 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4984 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4985 (if needs broadcasting) instead of broadcasting the packets one
4986 by one which would make a burst in the network traffic.
4988 * Added `broadcast' argument to the functions in silcd/server.[ch]
4989 silc_server_create_new_channel[_with_id] to indicate whether
4990 to send New Channel packet to primary router.
4992 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Added new function into the silcd/server.[ch] files:
4995 silc_server_create_new_channel_with_id to create new channel with
4996 already existing Channel ID.
4998 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4999 lib/silccore/silcpacket.h. This packet is used t send list of
5000 Set Mode payloads inside one packet. Server uses this to set
5001 the modes for the channels and clients on those channels, that it
5002 announced to the router when it connected to it. The protocol
5003 specification has been updated accordingly.
5005 * The silc_server_new_channel did not handle the packet coming
5006 from normal server as it normally does not send that. However,
5007 when it announces its channels it does send it. Implemented
5008 the support for that.
5010 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5011 into the file lib/silccore/id.h.
5013 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Fixed memory leaks in the functions silc_idlist_del_client,
5016 silc_idlist_del_channel and silc_idlist_del_server in the file
5017 silcd/idlist.c. All of those leaked like a sieve.
5019 * Fixed some small memory leaks in the client's function
5020 silc_client_notify_by_server.
5022 * Added functions into silcd/server.c: silc_server_announce_clients,
5023 silc_server_announce_channels and silc_server_announce_server.
5024 These functions are used by normal and router server to announce
5025 to its primary router about clients, channels and servers (when
5026 router) that we own. This is done after we've connected to the
5029 These functions effectively implements the following packet types:
5030 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5031 and SILC_PACKET_NEW_ID_LIST.
5033 * Added new functions into the silcd/packet_receive.[ch]:
5034 silc_server_new_id_list, silc_server_new_channel_list and
5035 silc_server_new_channel_user_list to handle the incoming
5036 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5038 * Added support of changing Channel ID in the function
5039 silc_server_replace_id. If the server that announces a channel
5040 to the router already exists in the router (with same name but
5041 with different Channel ID), router is responsible to send
5042 Replace ID packet to the server and force the server to change
5043 the Channel ID to the one router has.
5045 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5046 client that the Channel ID has been changed by the router. The
5047 normal server sends this to the client. Client must start using
5048 the new Channel ID as the channel's ID.
5050 Implemented handling of this new type into lib/silcclient/client.c
5051 into the function silc_client_notify_by_server.
5053 * Added new function silc_idlist_replace_channel_id into the files
5054 silcd/idlist.[ch] to replace the Channel ID.
5056 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Call silc_server_command_identify_check always when processing
5059 the IDENTIFY command in silcd/command.c
5061 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5064 send keepalive packets. The packet can be sent by clients,
5065 servers and routers.
5067 Added function silc_socket_set_heartbeat into the file
5068 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5069 If not set, the heartbeat is not performed. The actual
5070 heartbeat is implemented in the low level socket connection
5071 library. However, application is responsible of actually
5074 Added silc_server_send_heartbeat to send the actual heartbeat
5075 packet into silcd/packet_send.[ch]. Server now performs
5076 keepalive with all connections.
5078 * Added silc_task_get_first function into lib/silcutil/silctask.c
5079 to return the timeout task with shortest timeout. There was a bug
5080 in task unregistration that caused problems. TODO has been
5081 updated to include that task system must be rewritten.
5083 * The client library will now resolve the client information when
5084 receiving JOIN notify from server for client that we know but
5085 have incomplete information.
5087 * Rewrote parts of silc_server_remove_from_channels and
5088 silc_server_remove_from_one_channel as they did not remove the
5089 channel in some circumstances even though they should've.
5091 * Encryption problem encountered in server:
5093 The LEAVE command used to send the Channel Key packet to the
5094 router immediately after generating it. However, the code
5095 had earlier sent Remove Channel user packet but not immediately,
5096 ie. it was put to queue. The order of packets in the router
5097 was that Channel Key packet was first and Remove Channel User
5098 packet was second, even though they were encrypted in the
5099 reverse order. For this reason, MAC check failed. Now, this
5100 is fixed by not sending the Channel Key packet immediately but
5101 putting it to queue. However, this is more fundamental problem:
5102 packets that are in queue should actually not be encrypted
5103 because packets that are sent immediately gets encrypted
5104 actually with wrong IV (and thus MAC check fails). So, packets
5105 that are in queue should be encrypted when they are sent to
5106 the wire and not when they put to the queue.
5108 However, the problem is that the current system has not been
5109 designed to work that way. Instead, the packet is encrypted
5110 as soon as possible and left to the queue. The queue is then
5111 just purged into wire. There won't be any fixes for this
5112 any time soon. So, the current semantic for packet sending
5115 o If you send packet to remote host and do not force the send
5116 (the packet will be in queue) then all subsequent packets to the
5117 same remote host must also be put to the queue. Only after the
5118 queue has been purged is it safe again to force the packet
5121 o If you send all packets immediately then it safe to send
5122 any of subsequent packets through the queue, however, after
5123 the first packet is put to queue then any subsequent packets
5124 must also be put to the queue.
5126 Follow these rules and everything works fine.
5128 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Added new function silc_server_remove_clients_by_server to
5131 remove all client entries from ID list when the server connection
5132 is lost. In this case it is also important to invalidate all
5133 client entires as they hold the invalid server entry. This
5134 fixes fatal bug when server has lost connection and will reconnect
5137 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Made some sanity checks to silc_server_daemonise like to check
5140 whether the requested user and group actually exists.
5142 * Added sanity check to SKE's silc_ske_responder_finish to check
5143 that the public and private key actually is valid.
5145 * Invalidate the client's nickname when receiving Replace ID
5146 packet and the Client ID is being replaced. This means that the
5147 server will query the nickname if someone needs it (client)
5150 * Sort the ID Cache in client library when the ID Cache data
5151 has changed (needs sorting).
5153 * Do not allow for SILC client to create several connections to
5154 several servers. The client does not support windows right now
5155 and generating multiple connections causes weird behaviour.
5157 Irssi-silc client does support windows and can handle several
5158 connections without problems, see: www.irssi.org and SILC plugin.
5160 * Fixed some places where client was added to the IDList. The
5161 rule of thumb is following (in order to get everything right):
5162 If the client is directly connected local client then the
5163 `connection' argument must be set and `router' argument must be
5164 NULL to silc_idlist_add_client function. If the client is not
5165 directly connected client then the `router' argument must
5166 bet set and the `connection' argument must be NULL to the
5167 silc_idlist_add_client function.
5169 * The funtion silc_server_packet_send_local_channel actually did
5170 not check whether the client was locally connected or not. It
5171 does that now. Fixed a bug related to LEAVE command.
5173 * Fixed Remove Channel User payload parsing bug in server's
5174 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5176 * The server's silc_server_save_channel_key now checks also the
5177 global ID list for the channel as it might not be in the local
5178 list. Fixed a bug related to LEAVE command.
5180 * Is this the end of the [<unknown>] buglet that has been lurking
5181 around for a long time? A little for loop fix in server's
5182 silc_server_command_whois_parse that is used by both IDENTIFY
5183 and WHOIS command. At least, this was a clear bug and a cause
5184 of one type of [<unknown>] buglet.
5186 * WHOIS and IDENTIFY commands call the function
5187 silc_server_command_[whois/identify]_check function even if
5188 we are not router server.
5190 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Added --with-gmp configuration option. If set the GMP
5193 is always compiled in the SILC source tree. If not set then
5194 it is checked whether the system has the GMP3 installed. If
5195 it has then the GMP won't be compiled (the system's headers
5196 and library is used), if it doesn't have it then the GMP is
5197 compiled in the SILC source tree.
5199 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Changed RSA private exponent generation to what PKCS #1
5202 suggests. We try to find the smallest possible d by doing
5203 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5204 not security fix but optimization.
5206 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added new config entry [Identity] to fork the server and run
5209 it as specific user and group. A patch from Bostik.
5211 * Imported Dotconf configuration library into lib/dotconf.
5212 This will be used to create the SILC configuration files later.
5213 It will appear in the distsribution after this commit.
5215 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5217 * A big code auditing weekend happening. Auditing code for
5218 obvious mistakes, bugs and errors. Also, removing any code
5221 Removed files for being obsolete:
5223 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5224 inline in the file lib/silcutil/silcbuffer.h)
5226 o lib/silcutil/silcbufutil.c (the header has inline versions)
5228 Changed code to fix possible error conditions:
5230 o The buffer formatting routines now check that the destination
5231 buffer really has enough space to add the data. This applies for
5232 both buffer formatting and unformatting
5233 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5234 unformatting was changed to accomodate following rules:
5235 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5236 sent to the function while XXX_*STRING will not allocate or copy
5237 the data into the buffer. Instead it sets the pointer from the
5238 buffer into the pointer sent as argument (XXX_*STRING used to
5239 require that the pointer must be allocated already). This change
5240 makes this whole thing a bit more consistent and more optimized
5241 (note that the data returned in the unformatting with XXX_*STRING
5242 must not be freed now). The routines return now -1 on error.
5244 o Tried to find all code that use buffer_format and buffer_unformat
5245 and added return value checking to prevent formatting and
5246 especially unformatting errors and possible subsequent fatal
5249 o Changed ske->x and ske->KEY to mallocated pointers in
5250 lib/silcske/silcske.h. Fixed possible data and memory leak.
5252 o Added return value checking to all *_parse* functions. Fixed
5253 many memory leaks as well.
5255 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5256 so that buffer overflows would not happen. All code now also
5257 checks the return value as it can fail.
5259 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Added reconnection support to server if the normal server looses
5262 its connection to the router (for example if router is rebooted).
5263 The server performs normal reconnection strategy implemented
5264 to the server. Affected file silcd/server.c.
5266 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Added new packet type SILC_PACKET_SET_MODE that is used to
5269 distribute the information about changed modes (for clients,
5270 channels and clients channel modes) to all routers in the
5271 network. Updated the protocol specification accordingly.
5273 Added functions into silcd/packet_send.c and
5274 silcd/packet_receive.c: silc_server_send_set_mode,
5275 silc_server_set_mode.
5277 Added new files silcmode.[ch] into lib/silccore that implements
5278 the encoding and decoding of Set Mode Payload. Added new type
5279 SilcSetModePayload. Moved the definitions of different modes
5280 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5282 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Oops, a little mistake in server's connection authentication
5285 protocol. The protocol is not ended with FAILURE but with
5286 SUCCESS if the authentication is Ok. :) Affected file is
5289 * Implemented NICK_CHANGE notify handling in server in the file
5290 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5291 the local clients on the channel. After the changing nickname
5292 in router environment snhould work and the [<unknown>] nickname
5293 should appear no more.
5295 The silc_server_replace_id function that receives the Replace ID
5296 payload now sends the NICK_CHANGE notify type also in the file
5297 silcd/packet_receive.c
5299 * Changed WHOIS and IDENTIFY command to support the maximum amount
5300 of arguments defined in protocol specs (3328 arguments). This
5301 fixed a bug that caused problems when there were more than three
5304 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Added extra parameter, command identifier, to the
5307 silc_client_send_command so that explicit command identifier
5310 Changed that ID list routines uses specific command identifier
5311 when sending WHOIS/IDENTIFY requests to the server so that they
5312 can be identified when the reply comes back.
5314 Affected files lib/silcclient/command.[ch],
5315 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5317 * Added `sender' argument to silc_server_packet_send_to_channel
5318 to indicaet the sender who originally sent the packet to us
5319 that we are now re-sending. Ignored if NULL. Affected file
5320 silcd/packet_send.[ch].
5322 * Added some server statistics support in silcd/server_internal.h
5323 SilcServerStatistics structure and around the server code. Also
5324 send some nice statistics information when client is connecting
5327 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Fixed channel ID decoding in server's JOIN command reply in
5330 silcd/command_reply.c
5332 * Fixed braodcasting of replace ID payload to not to send it if
5333 we are standalone server in silcd/packet_receive.c.
5335 * Fixed all channel message sending routines to not to send
5336 packets to clients that has router set, since they are routed
5337 separately in the same function earlier. Affects file
5338 silcd/packet_send.c and all channel packet sending functions.
5340 * In USERS reply, res_argv[i] are not allocated, the table
5341 is allocated. Thus changed that free the table, not its
5344 * In server's whois_check and identify_check if the client is
5345 locally connected do not send any WHOIS commands - they are not
5348 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Fixed some minor bugs in client when sending WHOIS command. The
5351 arguments was in wrong order.
5353 * Removed statis function add_to_channel from server in
5354 silcd/command.c that was previously used with the joining but
5357 * Tested USERS command in router environment successfully with two
5358 routers, two servers and two clients.
5360 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Reorganized the USERS command and command reply in client library
5363 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5364 When the command is given by user we register a pending command
5365 callback that will reprocess the command after the reply has been
5366 received from the server. When reprocessing the packet we then
5367 display the information. Thus, the USERS information is displayed
5368 now in the command callback instead of in the command reply
5369 callback. The processing of the command is same as previously
5370 when server has sent the command reply in the JOINing process.
5372 * Added to USERS command in silcd/command_reply.c to join the client,
5373 we didn't use to know about, to the channel after we've created
5374 a client entry for it. Also, for clienet we did know already still
5375 check whether it is on the channel or not and add it if not.
5377 * Removed silc_server_command_join_notify as the function and its
5380 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5382 * Changed the client's pending command handling to the same as the
5383 server's pending command handling. It is also now possible to
5384 execute command reply functions from other command reply
5385 function as the function callbacks for commands and command
5386 replies are one and same. The pending commands are not static
5387 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5388 in client connection context. Thus, pending commands are server
5389 connection specific as it is convenient.
5391 Changed the function silc_client_command_pending and
5392 silc_client_command_pending_del and added new function
5393 silc_client_command_pending_check. Removed the
5394 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5397 * Added cmd_ident, current command identifier, to the client
5398 connection context in lib/silcclient/client.h to keep track on
5399 command identifiers used in command sending. Client's command reply
5400 function handling now supports the mandatory command identifiers.
5402 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5403 funtions in client to fully support pending command callbacks.
5405 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5406 as one of the arguments to the application in the command reply
5409 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5410 before first releasing SILC but came back. Now it is removed again
5411 and should come back nomore. The FORWARDED flag was used only
5412 by the JOINing procedure by forwarding the command packet to router.
5413 Now, the JOINing procedure has been changed to more generic (due
5414 to various router environment issues) and FORWARDED is not needed
5415 anymore for anything. The protocol specification is yet to be
5418 Now, removed silc_server_packet_forward from server and the flag
5419 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5421 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Renamed NAMES command to USERS command. The NAMES was named that
5424 due to historical reasons. Now it is renamed. Also, rewrote
5425 parts of the USERS command. The nickname list is not sent anymore
5426 by the server. Only Client ID and mode lists are sent in the USERS
5427 command. Changed this also to the protocol specification.
5429 The client now resolves the names and stuff after it receives
5430 the USERS list from the server when joining to the channel.
5432 * WHOIS and IDENTIFY commands has been changed to support multiple
5433 Client ID's per command. One can now search for multiple users
5434 in the network by sending only one WHOIS or IDENTIFY command.
5435 Changed the code and the protocol specifications.
5437 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5438 uses silc_server_command_whois_parse to parse the request. */
5440 * If normal server, do not parse the WHOIS and IDENTIFY requests
5441 before sending it to the router. Saves some time.
5443 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Fixed JOIN command on client library. Wrong number of arguments
5446 used to crash the client.
5448 * Added silc_server_channel_has_global function to check whether
5449 channel has global users or not.
5451 * Added silc_server_channel_has_local function to check whether channel
5452 has locally connected clients on the channel.
5454 * The silc_server_remove_from_one_channel now checks whether the
5455 channel has global users or not after given client was removed from
5456 the channel. It also checks whether the channel has local clients
5457 on the channel anymore. If it does not have then the channel entry
5458 is removed as it is not needed anymore.
5460 * The silc_server_notify now checks on JOIN notify whether the joining
5461 client is one of locally connected or global. If it is global then
5462 the channel has now global users on the channel and that is marked
5463 to the channel entry. Also, it now saves the global client to
5464 global list who is joining and JOINs it to the channel. This is
5465 for normal server, that is.
5467 Changed silc_server_send_notify_on_channel,
5468 silc_server_packet_relay_to_channel and
5469 silc_server_packet_send_to_channel check if we are normal server
5470 and client has router set (ie. global client) do not send the
5471 message to that client, as it is already routed to our router.
5473 * Implemented LEAVE notify type handling in silc_server_notify
5476 * Tested LEAVE command in router environment successfully. Tested
5477 with two routers, two servers and two clients.
5481 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5483 * Implemented SIGNOFF notify type handling in silc_server_notify
5486 * silc_server_remove_id now removes the client entry from all channels
5487 it has joined and thusly sends SIGNOFF notify type.
5489 * Rewrote the NAMES list generation in server by removing two excess
5490 loops. The lists are created now inside one loop.
5492 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * silc_server_remove_channel_user checks now also global list
5495 for channel and client.
5497 * silc_server_new_channel_user checks now both local and global
5498 list for channel and client. Fixed a bug in client id decoding.
5499 Used to decode wrong buffer.
5501 * silc_server_channel_message checks now both local and global
5502 list for channel entry.
5504 * Tested channel joining (hence JOIN) in router environment
5505 successfully. Tested with two routers, two servers and two
5508 * Tested channel message sending in router environment successfully.
5510 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Added silc_server_save_channel_key into server.[ch] to save the
5513 received channel key in Channel Key payload processing. It is
5514 also used in JOIN command reply handling.
5516 Equivalent function silc_client_save_channel_key added into
5517 client.[ch] into client library.
5519 * Changed JOIN command reply to send information whether the channel
5520 was created or not (is existing already) and the channel key
5521 payload. Changed protocol specs accordingly.
5523 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5524 the request was sent by ID and not by nickname. Crashed on
5527 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5530 now correctly save the received data.
5532 * silc_server_free_sock_user_data now notifies routers in the
5533 network about entities leaving the network.
5535 At the same time implemented functions silc_server_remove_id
5536 and silc_server_send_remove_id to receive and send REMOVE_ID
5537 packets. The packet is used to notify routers in the network
5538 about leaving entities. The ID removed will become invalid in
5541 * Added function silc_idlist_del_server into server. Removes and
5542 free's server entry from ID list.
5544 * silc_server_private_message function now checks, if we are router,
5545 that the destination ID really is valid ID, naturally.
5547 * In router when NEW_ID packet is received (for new client) the
5548 hash of the Client ID is saved in the ID Cache but the
5549 client->nickname is set to NULL, instead of putting the hash
5552 IDENTIFY command now also checks that client->nickname must be
5553 valid. If it is not if will request the data from the server who
5554 owns the client. Added new function
5555 silc_server_command_identify_check.
5557 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5558 to set the command to already allocated Command Payload.
5560 * Tested private message sending in router environment with two
5561 routers, two servers and two clients. Fixed minor bugs and now
5564 * Fixed segfault from client's NAMES command. Used to crash if
5567 * Forwarded packets must not be routed even if it is not destined
5568 to the receiver. Changed server code comply with this.
5570 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Added `require_reverse_mapping' boolean value to ServerParams
5573 structure. If TRUE (not default) the server will require that
5574 the connecting host has fully qualified domain name.
5576 If the reverse mapping is not required and hostname could not be
5577 found the IP address is used as hostname.
5579 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Implemented version string checking to both client and server.
5582 The check is incomplete currently due to the abnormal version
5583 strings used in development version of SILC.
5585 * Changed all command functions in server to use the new
5588 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Changed char *data to unsigned char *data in ID Cache system to
5591 support binary data as ID Cache data. Changed code to support
5592 binary data in lib/silccore/idcache.c.
5594 * Renamed silc_server_packet_relay_command_reply to
5595 silc_server_command_reply as it is normal packet receiving
5596 function. Rewrote the function to accept command replys for
5597 servers and not only for clients.
5599 * Mark remote router always as registered server if we are connecting
5600 to it. Otherwise, commands sent by the router to us are ignored.
5602 * All ID List find routines now returns the ID Cache Entry pointer
5603 as well if requested.
5605 * WHOIS command works now in router environment, tested with two
5606 routers, two servers and two clients.
5608 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5609 in router environment (as it is almost equivalent to WHOIS) but
5610 hasn't been tested thoroughly. Added new functions:
5612 silc_server_command_identify_parse
5613 silc_server_command_identify_send_reply
5614 silc_server_command_identify_from_client
5615 silc_server_command_identify_from_server
5617 * Disabled route cache adding because adding two different ID's with
5618 same IP replaces the old cache entry thus giving wrong route.
5619 The entry->router->connection is always the fastest route anyway
5620 so route cache may not be needed. Of course, new routes maybe
5621 established after receiving the ID when the entry->router->connection
5622 might not be anymore the most optimal.
5624 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Add route cache for received ID for fast routing.
5628 * Added silc_server_packet_route to route received packet on router
5629 that is not destined to us.
5631 * Renamed silc_server_get_route to silc_server_route_get.
5633 * Added id_string and id_string_len fields into SilcServer to
5634 include encoded ServerID for fast comparing without excess
5635 encoding of the ID's.
5637 * Cleaned up WHOIS command on server side. Added following static
5640 silc_server_command_whois_parse
5641 silc_server_command_whois_check
5642 silc_server_command_whois_send_reply
5643 silc_server_command_whois_from_client
5644 silc_server_command_whois_from_server
5646 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5647 arguments in command replies. All command functions should be
5648 updated to use this macro.
5650 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Minor typo fixes on command reply handling on server.
5654 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Added silc_server_command_add_to_channel internal routine to add
5657 the client to the channel after router has created the channel and
5658 sent command reply to the server.
5660 * Added generic silc_server_send_command to send any command from
5663 * Use static buffer with ID rendering instead of duplicating data.
5665 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Fixed a channel user mode bug when joining to a channel server gave
5668 everybody channel founder rights, oops.
5670 * We mark ourselves as the router of the incoming server connection
5671 if we are router ourselves. This way we can check in some packet
5672 sending functions whether it is locally connected server. For
5673 incoming router connections we put NULL.
5675 * For router sending packets locally means now always sending the
5676 packet cell wide; to local clients and local servers. For normal
5677 server sending packet locally means sending it to only local
5680 * Fixed the JOIN command to really work in router environment. If the
5681 channel is created it is always created by the router. Router is
5682 also responsible of making the initial joining to the channel,
5683 sending JOIN notify to the sending server and distributing
5684 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5685 does not exist server doesn't do anything else but forward the
5686 command to the router which performs everything.
5688 * Added silc_server_send_channel_key function to send the Channel Key
5691 * Added silc_server_create_channel_key to create new channel key. The
5692 channel key is now re-generated everytime someone joins or leaves
5693 a channel, as protocol dictates. Note: channel->key_len is the
5696 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5699 packet_receive.[ch] to separate packet sending and receiving
5700 routines. The server.[ch] now includes everything else including
5701 actual packet processing (writing and reading data) and other
5704 Renamed silc_server_private_message_send_internal to
5705 silc_server_send_private_message. The routine is still though
5706 used only to relay private messages as server does not send
5707 private messages itself.
5709 Renamed silc_server_new_channel to silc_server_create_new_channel
5710 and added new function sicl_server_new_channel that handles the
5711 incoming New Channel packet. Added also new sending function
5712 silc_server_send_new_channel to send New Channel Payload.
5714 * Added new function silc_server_notify to process incoming notify
5715 packet to the server/router. Server may then relay the notify
5716 to clients if needed.
5718 * Added new function silc_server_new_channel_user to process incoming
5719 New Channel User packet. Router will redistribute the packet and
5720 send JOIN notify to its local clients and locally connected servers
5721 if needed. Normal server will send JOIN notify to its local client
5722 on same channel when received this packet. Added also corresponding
5723 sending function silc_server_send_new_channel_user to sent the
5726 * Added boolean route argument to send_notif_to_channel and
5727 packet_send_to_channel functions to attempt to route the packet
5728 if it is TRUE and send only locally if it is FALSE.
5730 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * silc_server_replace_id now broadcasts the received replace ID
5733 packet if it is not broadcast packet already. The router must
5734 broadcast to inform other routers about changed ID.
5736 * Added backpointer to server's router into SilcServer context in
5737 silcd/server_internal.h.
5739 * Fixed silc_server_packet_broadcast to send correct broadcast
5742 * The channel key is now distributed to the local client as soon
5743 as it is received from the router (in router environment) so that
5744 no other packet may be sent for the channel until client has
5747 * silc_server_remove_channel_user now broadcasts the received
5748 Remove Channel User packet if it is not broadcast packet already.
5749 The router must broadcast to inform other routers about removed
5752 * Added users field into SilcPacketContext that is a reference count
5753 of the context. One can increase the reference count by calling
5754 silc_packet_context_dup which is now changed to just increase the
5755 reference count instead of duplicating the data. The reference
5756 count is decresed by calling silc_packet_context_free that will
5757 free the data after the reference count hits zero.
5759 For now on the packet context and everything allocated into it
5760 (including the raw packet from network) must be freed by calling
5761 the new silc_packet_context_free function. Added also new function
5762 silc_packet_context_alloc that must be used now to allocate the
5763 context. This also means that if a routine is asynchronous from
5764 silc_[client/server]_packet_parse_type the packet context must
5765 be duplicated by calling silc_packet_context_dup. Otherwise it
5766 gets free'd after silc_[client/server]_packet_parse_type returns.
5767 Also, one must remember that if packet is duplicated then its
5768 reference count must be decresed by calling the free function as
5769 many times as it was duplicated.
5771 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5772 from both client and server.
5774 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Made joining to a channel working in router environment.
5778 * Cleaned up JOIN command on server side and create function
5779 silc_server_command_join_channel internal routine to make the
5782 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Changed silc_command_pending list to SilcDList. Also, added
5785 `ident' field to SilcServerCommandPending structure to identify
5786 the reply and to call correct callback.
5788 Added silc_server_command_pending_check function to replace the
5789 corresnponding macro. The silc_command_pending list is not
5792 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5793 to set identifier to previously allocated Command Payload. It
5794 is used to set identifier for command when resending Command
5797 * Added silc_command_payload_encode_payload to encode Command
5798 Payload buffer from SilcCommandPayload structure.
5800 * Added silc_argument_payload_encode_payload to encode Argument
5801 payload buffer from SilcArgumentPayload structure.
5803 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Changed WHOIS command to support router connection on server side.
5806 The whois request is always sent to router unless the server is
5807 standalone server. After server has received the reply from the
5808 router will it send the reply to the client.
5810 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5811 broadcast received broadcast packet. The function is used only
5812 by router. The broadcast packet is always sent to the router's
5815 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5816 render given ID to printable string, for log files for example.
5818 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Made basic router to router connections working. At least they
5821 can now connect to each other but nothing really works the way
5822 they are supposed - yet.
5824 * Added new initiator token to RouterConnection configuration
5825 file in silcd/serverconfig.[ch]. It is used to tell whether we
5826 are the initiator to the remote router or whether we'll expect
5827 the other end to connect.
5829 * Moved registering of listener task to silc_server_init, hence
5830 the server starts listenning as soon as it is run, even if it
5831 does not have connections to other routers. Let's see how well
5834 * Changed default connection retry timeouts for more suitable in
5837 * Removed cipher and such arguments from silc_idlist_add_client
5838 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5839 Added new function silc_idlist_add_data to add the keys and stuff
5842 * Added SilcIDListData structure and added it to SilcClientEntry
5843 and SilcServerEntry as their first field in the structure. This
5844 way we can explicitly cast the ID entries to the SilcIDListData
5845 structure and get common data for the entries. In past, we had
5846 to first check what type of connection it is and then cast it to
5847 correct ID entry type. Now, we can directly cast the opaque
5848 pointer to the SilcIDListData (no matter what ID entry it actually
5849 is) and get the data needed.
5851 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5854 in some circumstances even if threre were timeout tasks, though not
5855 IO tasks, but tasks anyway. Now fixed.
5857 * Defined SilcServerConnection structure to hold connection specific
5858 stuff about directly connected servers and routers. The definition
5859 is currently in silcd/server_internal.h. I thought about having
5860 a bit more important role fro this struct but for now it is used
5861 only when connecting to other server (or router actually).
5863 * Added connecting retry support in server when connecting to
5864 router(s). The retry feature implement exponential backoff
5865 algorithm. Also, added SilcServerParams structure to hold default
5866 parameters for server. For now, it include these retry settings
5867 and are hard coded. After server is moded to be as Silc Server
5868 Library this structure will be more important.
5870 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Changed client librarys channel->clients table to SilcList and
5873 changed code accordingly.
5875 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Changed client's channel table to SilcList and changed code
5878 accordingly. Also changed SilcChannelClientEntry to include back-
5879 pointer to the channel so that client entry can use that structure
5880 as list as well and we have fast cross-reference to the channel.
5881 This change dramatically decreased the complexity of channel
5882 handling with client entry and vice versa (removed one extra
5883 loop when searching for channel entry from many functions).
5885 * Changed server->sim from table to SilcDList and changed code
5888 * NAMES command can now be used from user interface. It will show
5889 the user list on the channel, neatly.
5891 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5892 Code now saves realname of the user if it becomes available.
5894 * Renamed configure.in to configure.in.pre and made ./prepare
5895 script to automatically add correct version string to
5896 configure.in which it creates from configure.in.pre.
5898 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * NAMES command reply now shows users mode with the nickname when
5903 * Moved silc_client_ch[u]mode[_char] functions from
5904 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5905 place sucks, they are utility functions and should be in some
5908 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5910 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5913 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Added TRQ (efficient deque and list library) into lib/trq. This is
5918 a very good list library that is currently used in the SILC. Defined
5919 SilcList API over the library because I didn't like the API very
5920 much. See lib/trq/silclist.h for the API and examples of how to
5921 use the API. Fixed various places in the code to use the new
5922 SilcList API. The SilcList is meant for lists that has a structure
5923 already defined as a list. It is not suitable to add just some
5924 context to the list (in TRQ, the context is the list actually).
5926 So, I defined SilcDList that can be used for the purpose where
5927 predefined list structure does not exit. This can be used as
5928 such list. Now some context just can be added to the SilcDList.
5929 Currently this list is not used in the SILC just yet, though there
5930 are a lot places where this can replace dynamically allocated
5931 tables and I will fix these places, later, to use SilcDList.
5932 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5933 and use TRQ internally).
5935 Also fixed some annoying warning messages that the original TRQ
5936 code generated. Also minor changes to TRQ's Makefile.in.
5938 * Added support for querying by Client ID to both WHOIS and
5939 IDENTIFY commands into server, as required by the protocol.
5941 * Removed method function pointers from SilcBuffer structure. They
5942 weren't used to anything and just increased the context size for
5943 no good reason. This change also made silc_buffer_alloc and
5944 silc_buffer_free functions inline functions.
5946 * Disabled command flooding detection support until it's fixed so
5947 that it accepts commands in but does not execute them more than once
5950 * Added silc_net_localhost(), to return local hostname, into
5951 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5952 that must be initialized before calling silc_client_init.
5954 * Added new function: silc_server_send_notify_on_channels to send
5955 notify messages to all channels client has joined. It is assured
5956 that the message is sent only once per client.
5958 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5959 lib/silcutil/silcutil.[ch] as silc_format function. The new
5960 function is generic and is used by server as well, not only by
5961 the logging routines.
5963 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5964 the provided version string was not acceptable. Added new function:
5965 silc_ske_check_version into lib/silcske/silcske.h. The function
5966 must be implemented by the application (client or server) and it
5967 does not reside in the SKE library. The function checks the version
5968 string remote end sent.
5970 * Added back pointers (to opaque context and to SilcSocketConnection)
5971 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5973 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5974 duplicate packet context structure.
5976 * Changed `notify' client operation to send same arguments as client
5977 receives from server except for ID's. ID's are mapped to correct
5978 ID entry and that is returned. Also, if channel entry is not sent
5979 by server but the notify is for channel the channel entry is sent
5980 to application (otherwise application doesn't know that it is for
5981 channel (library gets it from packet's Destination ID)).
5983 * Added silc_client_remove_from_channels into client library to
5984 remove a client from all channels it has joined to. Used when
5985 received SIGNOFF notify from server. Added also new function
5986 silc_client_replace_from_channels to replace old ID entry with
5987 new ID entry on all channels. Used when received NICK_CHANGE
5990 * Fixed ID Cache list handling in silc_idlist_get_client in
5991 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5992 to get (or query) client by ID.
5994 * Updated TODO list.
5996 * Added connection authentication status message defined by the
5997 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5998 support for these into the code in client and server side.
6000 * Added generic function silc_client_send_command to send any command
6001 with variable argument list. Application should use this function
6002 to send commands if the command functions provided by the library
6003 does not suite for the application's user interface needs.
6005 * Added new `failure' client operation. Application is notified about
6006 received failure packet if client is executing a protocol. In this
6007 case the protocol's execution has failed.
6009 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6010 is required by the protocol.
6012 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6013 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6016 * Added status flag to SilcSKE object to indicate realtime status
6017 of the SKE protocol.
6019 * Application receives now exactly same command reply arguments as
6020 the library receives from server. However, if ID is received the
6021 corresponding ID entry is returned to the application (eg. Client
6022 ID is mapped to correct SilcClientEntry entry and that is returned).
6023 Changed command_reply client operation due to this change.
6025 * Changed all ID's in commands and in command replys as ID Payloads.
6026 Change affected both client and server side codes.
6028 All ID's sent in SILC network (with execption of ID's in SILC
6029 Packet header) are sent in ID Payload to support variable length
6032 * Server now notifies nick changes and notifies all clients on
6033 the channels about the new nickname (about the new Client ID,
6036 * Implemented CMODE command to change channel modes. Supports all
6037 channel modes defined by the protocol specs except ban and invite
6038 lists. (Also, private channel key mode is supported but support for
6039 setting private channel key in client is missing, thus, this mode
6040 has no effect on client side (except that server requires that the
6041 client uses private channel key and normal channel traffic does not
6044 Also, invite mode works per se, but INVITE command does not work
6045 yet correctly, so you can set channel as invite only channel but
6046 inviting clients to the channel does not work (it is yet to be
6047 thought what's the best way to do it).
6049 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6050 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6051 Implemented CUMODE command to change user's mode on the channel.
6052 Supports all modes defined by the protocol specs.
6054 * Added NAMES command reply to return users modes on the channel.
6056 * Removed unnecessary and slow ciphers from lib/silccrypt.
6058 * Set SO_KEEPALIVE option to connection sockets by default.
6060 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6062 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6063 redefined the Notify Payload into protocol specs.
6065 * Added silc_id_payload_parse_id to get ID directly from raw
6068 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6070 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6071 accept searching by Client ID as well.
6073 * Added support for LEAVE and SIGNOFF notify types in client library.
6075 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6076 to parse ID Payload from raw data.
6078 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added flags parameter into silc_ske_assemble_security_properties
6081 function in lib/silcske/silcske.[ch].
6083 * Changed notify client operation to fit better for notify messages
6084 sent by server. The notify payload received from server is now
6085 passed to the application (after parsing it to SilcNotifyPayload).
6086 It is application's responsibility to retrieve the arguments
6087 from the payload and show the message the way it wants. The message
6088 sent by server is implementation specific.
6090 * Changed public keys to comply with the protocol specification.
6091 Old public keys are not supported anymore and are not compatible.
6093 * Removed nickname from Channel Payload as the latest draft removed
6094 it. The client must resolve the nickname from the NAMES command
6095 reply received when it joined the channel.
6097 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6099 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Fixed some errors in protocol specification drafts.
6103 * Created lib/silccore/silcnotify.c to implement Notify Payload
6104 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6105 generic payloads described by protocol specifications. The file
6106 includes implementations for ID Payload and Argument Payload.
6108 * Changed Command Payload implementation to use the new Argument
6109 Payload. Changed command_xxxx_payload to command_payload_xxxx
6110 to comply with SILC coding conventions.
6112 * Added suppport for Argument Payload handling in Notify Payload
6113 implementation as protocol requires it. Added the new support
6114 into server and client lib as well.
6116 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Added support for multiple nicknames on same channel. [n] is
6119 added locally to the nickname if there are more than one same
6120 nicknames on the channel.
6122 * Server now sends all nicknames that matched WHOIS request.
6123 Client also shows the list received from server.
6125 * Added TOPIC command to client side. User can now set and show
6126 current topic on channel.
6128 * Added MOTD command to client and server. Also, server sends the
6129 motd when client connects to the server.
6131 * Changed version strings to comply ISO 8601.
6133 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed protocol error handling in client library. It should now
6136 cope even if the SKE fails for some reason.
6138 * Made new protocol specification drafts for submitting to IETF.
6140 * Implemented TOPIC command to server in silcd/command.c.
6142 * Added two new notify types into lib/silccore/silcnotify.h:
6143 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6144 notify nickname change and topic setting/change on a channel.
6146 * API change of command_reply operation in client library. The
6147 application gets now the status type received from server as well.
6149 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6153 * Cras fixed and optimized the packet handling even further and
6154 it should work now. Minor change to the prototype of function
6155 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6157 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Added new function into lib/silcutil/silcschedule.[ch]:
6160 silc_schedule_with_fd to select() a specified fd. The function
6161 returns after timeout expires or data arrives or goes. The
6162 function is used by packet routines to wait that all data is
6163 received from network.
6165 * Fixed data reading from network in lib/silccore/silcpacket.c.
6166 The code now assures that all data is read from the fd and then
6167 continues packet processing. This was a bug fix since the code
6168 used to drop some data in some circumstances.
6170 * Added new function into lib/silcclient/client.[ch]:
6171 silc_client_start_key_exchange to start key exchange after
6172 connection has been established to server. The code internally
6173 now uses this funtion but its main purpose was to provide it
6174 for applications that perform their own connecting. After
6175 application has created a connection it merely calls this
6176 function to start the key exchange between client and server.
6177 The library takes care of everything else after that.
6179 Updated also lib/silcclient/README to explain the usage of
6182 * Do not send to application information that connection has
6183 been established. Application gets notified it by connect
6186 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Applied cras's patch to add silc_schedule_one function. The
6189 function runs scheduler once and returns.
6191 * Fixed the scheduler after cras messed it up. The timeout
6192 handling works now as it's supposed to work.
6194 * Added into lib/silccore/ silcnotify.h to include notify
6195 message types support. Changed silc_server_send_notify*
6196 functions, in server.[ch], to support those new notify types.
6197 Added the support for the notify types into client library,
6198 as well. Added new notify client operation into ops.h in
6201 * Changed silc_server_packet_send_to_channel to send normal
6202 packets instead of just channel message packets. The function
6203 is now used to send the notify packets to channels. It is not
6204 used to send channel message packets anymore, as server never
6207 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6208 va_arg()s as it seems to require it nowadays. I guess, if SILC
6209 is compiled with older va_arg() the new code should work anyway.
6211 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Splitted core library. Core library (lib/silccore) includes
6214 now only SILC protocol specific core (and common) components.
6215 Created new utility library (lib/silcutil) that includes more
6216 generic purpose stuff. The stuff for util library was taken
6217 from the old core library. This was minor and easy split.
6219 * Created SILC Client Library (lib/silcclient) that includes
6220 implementation of the SILC client without user interface. This
6221 was major move from silc/ directory. The code has been changed
6222 so that it is transparent towards the user interface. The
6223 silc/ directory includes now the same user interface as before
6224 and it uses the new client library. Read lib/silcclient/README.
6225 Basicly, the client library performs everything else related
6226 to SILC except user interface handling. Also, configuration
6227 files are considered to be part of user interface and library
6228 does not handle them.
6230 This change also changed a lot of structures, function naming etc.
6231 Most important change was that SilcClientWindow object was
6232 renamed to SilcClientConnection in the client library. Created
6233 also new file lib/silcclient/ops.h. Also added new files
6234 silc/local_command.[ch] and silc/client_ops.[ch].
6236 All these changes were made to make it easier for user interface
6237 designers to create what ever user interface for the SILC client
6240 It is also expected that the server will be moved to lib
6241 directory as well and SILC Server Library will be created;
6242 sometimes in the future.
6244 * Removed Local commands from lib/silccore/silccommand.h as
6245 they are application specific and new client library does not
6246 handle any of those anymore.
6248 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6249 old client implementation in silc/.
6251 * Added support for callback functions in SILC_LOG_* macros.
6252 Application can now set its own callbacks that will be called
6253 instead of using the default functions that will always print
6254 the debug messages to stderr (or stdout). Also, debugging can
6255 now be disabled by setting silc_debug to FALSE and re-enabled by
6256 setting it to TRUE. Note, that logging will still work even
6257 if debugging is disabled.
6259 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6260 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6261 silc_log_reset_debug_callbacks.
6263 * To enable debugging in silc client one must give now -d
6264 option on command line.
6266 * Changed silc_schedule_init to automatically allocate task queues
6267 if they are not allocated before calling it.
6269 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Added GMP 3.1 into math library.
6273 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6276 a channel in SILC network. The packet is used by servers and
6277 routers to notify other routers that user has left a channel.
6278 This little feature was missing until now. Added the feature
6279 to protocol specification as well.
6281 Added functions: silc_server_send_remove_channel_user and
6282 silc_server_remove_channel_user into server.[ch].
6284 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6285 lib/silccore/silcpacket.h. However, they are not implemented
6288 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Fixed joining to a channel and sending channel messages
6291 between server and router. The channel message sending should
6292 now work inside a cell.
6294 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Fixed the private message sending between server and router.
6297 The private message sending should now work inside a cell.
6299 * Added silc_server_replace_id into server.[ch] to replace
6300 existing ID in the SILC network.
6302 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6303 and silc_idlist_replace_server_id into idlist.[ch] in server.
6305 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Fixed the server to server connections. Server can again now
6308 connect to router. Router to router connections probably does
6311 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Added dynamic protocol registering support. Now protocols can
6314 registered and unregistered on the fly. Patch by cras.
6316 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Added lib/contrib directory to hold routines that some platforms
6319 don't have but are needed by SILC.
6321 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6322 into lin/contrib to provide getopt() and getopt_long() for
6323 those who don't have it.
6325 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Added AWAY command to client. When away message is set and
6328 client receives a private message packet the client automatically
6329 replies to the sender with the away message.
6331 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6332 bug seemed to be the cause of recent problems when compiling
6335 * Added version detection support to SKE protocol specification
6336 and added the new changes to the SKE implementation as well.
6337 There were other minor changes in the SKE protocol as well.
6339 Many changes in lib/silcske/silcske.[ch] and in
6340 lib/silcske/payload.[ch].
6342 * Added ^U functionality, clear input line. Patch from cras.
6344 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Mainly small bugfixes on core library. Fixed some debugging
6347 logging and buffer overflow in silclog.c.
6349 * Updated config.sub and config.guess on the distribution tree.
6351 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Added command lagging support in server. Client may execute
6354 commands now only once in two seconds.
6356 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Optimized packet reception. MAC computation and checking is now
6359 also more optimized. A lot previously duplicated code is now
6360 used as generic by both client and server.
6362 * Fixed key pair generation in clientutil.c
6364 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6366 * Added into lib/silccore/silcbufutil.[ch] new function;
6367 silc_buffer_realloc.
6369 * Moved generic packet sending/encryption functions to
6370 lib/silccore/silcpacket.[ch] from client and server. Some
6371 rewriting of the functions.
6373 * Moved all generic packet reception/decryption functions to
6374 lib/silccore/silcpacket.[ch] from client and server. The
6375 packet processing is now much cleaner in both client and server.
6376 These were major changes in both client and server.
6378 * Created many common functions in server to do packet sending.
6379 Previously code were duplicated a lot, this has been removed
6382 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Rewrote major parts of the ID cache system. Don't know
6385 whether it is better now or not but at least the API is more
6388 * Major rewrite on ID cache stuff on client because of the ID
6389 cache API changes. Added idlist.c to client.
6391 * Also major rewrite on ID cache stuff on server as well.
6392 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6393 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6394 in hand, instead they are all put into the ID cache system now.
6395 All server_idlist_* routines uses ID cache now instead of
6396 traversing its own lists (those lists does not exist anymore).
6397 SilcIDList though still exists. Also, SilcXXXEntry's are
6400 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Finally made the SKE implementation compliant to the protocol
6403 specification. All mp integers are now binary encoded as
6404 opposed being HEX encoded.
6406 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6409 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6410 functions: silc_[encode/decode]_pem. Also added function
6411 silc_encode_pem_file to PEM encode with newlines ('\n') for
6414 * SILC public keys are now encoded either PEM or binary. Same
6415 option is for private keys as well. By default private keys
6416 are binary encoded and public keys PEM encoded. Silly HEX
6417 encoding were removed.
6419 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6420 function to create fingerprints.
6422 * Fixed a bug in SHA1; does not change the original data anymore.
6424 * Partly implemented INFO command on client and server side.
6425 Fixed CLEAR command. Changes to SERVER command; show current
6426 server(s) when giving command without arguments. Added
6427 VERSION command to client.
6429 * Added check to server that unregistered connections cannot
6430 execute commands (unless it is specificly allowed).
6432 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Fixed screen refresh.
6436 * Fixed channel joining bug from client. On some circumstances
6437 client tried to join to a channel it had already joined.
6439 * Added public key verification process into client's protocol.c.
6440 The client now verifies the public key from user and saves
6441 it into ~./silc/serverkeys/ directory.
6443 Added into: clientutil.[ch]: silc_client_verify_server_key.
6445 * Changed SKE protocol's silc_ske_initiator_finish function
6446 to accept callback function that verifies the received public
6447 key. Removed old silc_ske_verify_public_key function.
6449 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6452 silc_pkcs_private_key[_data]_set.
6454 * Made the password and public authentication more cleaner in
6455 server's protocol.c.
6457 * Removed historic and obsolete protocol `channel_auth' from
6458 both client and server.
6460 * Removed wrong way of sending command status messages from
6461 server to client in server's command.c. The old way violated
6462 protocol specification.
6464 Changes to silccore/silccommand.[ch]: removed
6465 silc_command_encode_status_payload -> not needed anymore,
6466 changed silc_command_encode_payload_va to accept extra
6467 argument on variable argument list. The argument type must
6468 now be provided to the function. Also, added new function:
6469 silc_command_encode_reply_payload_va which is same as
6470 normal command_encode_payload_va except command status type
6471 is provided as extra argument.
6473 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Added ~./silc directory handling. The directory includes the
6476 public and private keys for the client.
6478 Added silc_client_check_silc_dir, silc_client_create_identifier
6479 and silc_client_load_keys.
6481 * Implemented SILC protocol compliant public key. Added public
6482 and private key saving to and loading from files.
6484 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
