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

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

629 * Added silc_pkcs_public_key_compare to compare two
630 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
632 * Check that the client who set the founder mode on the
633 channel is the same client that is giving the founder
634 mode to itself. It is done by comparing the saved public
635 key (it is saved even in the authentication is passphrase).
636 Affected file silcd/command.c.

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

673 * Defined to WHOIS command reply the sending of fingerprint
674 of the client's public key (if the proof of posession of the
675 corresponding private key is verified by the server).
676 Updated to the protocol specification.
678 * Added support of receiving the client's public key's
679 fingerprint in command reply in client library. Affected
680 file is lib/silcclient/command_reply.c, and
681 lib/silcclient/idlist.[ch].

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

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

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

889 Make sure also that USERS command reply does not resolve
890 twice information. Affected file is
891 lib/silcclient/command_reply.c.
893 Make sure that silc_client_get_clients_by_list does not
894 resolve twice same information.

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

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

1008 router environment. Affected file silcd/server_backup.c.
1010 * Route packet only to one router in the function
1011 silc_server_packet_send_to_channel. Affected file is
1012 silcd/packet_send.c.
1014 * Fixed silc_server_send_notify_dest to set the broadcast
1015 flag. Fixed the silc_server_send_notify_topic to actually
1016 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1017 Affected file silcd/packet_send.c.
1019 * Changed the SFTP Filesystem interface. Changed the
1020 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1021 the filesystem operation function. The SilcSFTPFilesystem
1022 is now a context that is allocated by all filesystem allocation
1023 functions and it already includes the operations structure
1024 and filesystem specific context. It is given as argument
1025 now to the silc_sftp_server_start. This made the interface
1026 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1027 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1029 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Changed the backup router adding and getting interfaces
1032 in the server. The router that will be replaced by the
1033 specified backup router is now sent as argument. Affected
1034 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1037 * Added silc_net_addr2bin_ne to return the binary form of
1038 the IP address in network byte order. Affected files

1094 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1095 in the server to indicate disabled entry. All data read
1096 from the connection will be ignored and no data is sent
1097 for entry that is disabled. Affected files are
1098 silcd/idlist.h, silcd/server.c.
1100 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1111 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Implemented the SFTP (SSH File Transfer Protocol) to the
1114 lib/silcsftp. It includes SFTP client and SFTP server
1117 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Moved lib/silccore/silcprotocol.[ch] to the
1120 lib/silcutil library.
1122 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1123 take variable argument list pointer as argument. Affected
1124 file lib/silcutil/silcbuffmt.[ch].
1126 * Added silc_buffer_set function that is used to set data
1127 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1128 Affected file lib/silcutil/silcbuffer.h.
1130 * Changed various routines in the core library to use the new
1131 silc_buffer_set instead of allocating new buffer only for
1134 * Added 64-bit value formatting and unformatting support to the
1135 silc_buffer_[un]format routines. Affected file is
1136 lib/silcutil/silcbuffmt.[ch].
1138 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1139 to includes/bitmove.h.
1141 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * Fixed channel user mode saving in client library. Affected
1144 file lib/silcclient/command[_reply].c.
1146 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Defined the file transfer to the SILC Protocol. Added
1149 new packet type SILC_PACKET_FTP and defined File Transfer
1150 Payload. The mandatory file transfer protocol is SFTP
1151 (SSH File Transfer Protocol). Affected file in addition
1152 of the internet draft is lib/silccore/silcpacket.h.
1154 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1155 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1156 is used as part of backup router protocol when the primary
1157 router of the cell is back online and wishes to resume
1158 the position as primary router.
1160 * Redefined the MAC generation keys in the protocol. The
1161 same key is not used anymore in both direction. Both
1162 direction will now use different keys for sending and
1163 receiving. This fixes a potential security flaw. This
1164 change causes incompatibilities in the protocol.
1166 * Redefined also the MAC computation from the packet.
1167 An packet sequence number is now added to the MAC
1168 computation. This prevents possible replay attacks against
1169 the protocol. This change too causes incompatibilities
1172 Added `sequence' field to the SilcPacketContext to hold
1173 the current sequence number for the packet.
1175 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * Added `created' field to the SilcIDListData in the file
1178 silcd/idlist.h to indicate the time when the entry was
1181 * Added `created' field to the SilcChannelEntry too. Affected
1182 file silcd/idlist.h.
1184 * Added `creation_time' aguments to all the announcement functions
1185 in the server. If it is provided then only the entries that
1186 was created after the provided time frame are actually
1187 announced. Affected file silcd/server.[ch].
1189 * The protocol says that the Channel ID's IP address must be
1190 based on the router's IP address. Added check for this in
1191 the silc_server_new_channel when processing incoming New Channel
1192 Payload. Affected file silcd/packet_receive.c.
1194 * Print out the correct version with --version in SILC client.
1195 Affected file irssi/src/silc/core/silc-core.c.
1197 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Fixed WHOWAS command to check for completnes of the client
1200 entry always, not just when the command is coming from client.
1201 Affected file silcd/command.c.
1203 * Added new function silc_server_packet_queue_purge to purge the
1204 outgoing data queue to the network. After the function returns
1205 it is guaranteed that the outgoing packet queue is empty.
1206 Affected file silcd/packet_send.[ch].
1208 * Purge the outgoing packet queue in the rekey protocol's final
1209 callback to assure that all rekey packets go to the network
1210 before quitting the protocol. Affected file silcd/server.c.
1212 * Added silc_client_packet_queue_parse as similar function as
1213 in server to the client library. The affected file is
1214 lib/silcclient/client.c.
1216 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Splitted silcd/server.c and created silcd/server_util.[ch]
1219 for utility functions.
1221 * Added new socket flag SILC_SF_DISABLED to indicate that the
1222 connection is open but nothing can be sent to or received from
1223 the connection. Affected file lib/silcutil/silsockconn.[ch].
1224 The checking for disabled socket is checked in the low level
1225 silc_socket_write and silc_socket_read functions.
1227 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Allow only nicknames and channel names that fits into the
1230 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1232 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1234 * When processing JOIN command reply in server check that if
1235 the channel exists in our global list we'll move it the local
1236 list. Affected file silcd/command_reply.c.
1238 * Fixed the check whether client is joined on the channel already
1239 in JOIN command. Affected file lib/silcclient/command.c.
1241 * Fixed the JOIN command reply to check whether the channel
1242 already exists. Affected file lib/silcclient/command_reply.c.
1244 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * Added silc_ske_status_string to map the SKE error numbers
1247 to readable strings. The affected files are
1248 lib/silcske/silcske[_status].[ch].
1250 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Do not show the private channels on the WHOIS channel list
1253 as it is not allowed by the protocol. The affected file is
1256 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Assure that the packet length digged from the actual packet
1259 is something sensible in the silc_packet_decrypt_rest_special
1260 in lib/silccrypt/silcpacket.c.
1262 * Free and NULL the allocated pointer in silc_hmac_alloc if
1263 the HMAC allocation fails. The affected file is
1264 lib/silccrypt/silchmac.c.
1266 * Print the selected security properties to the log files in
1267 the server. Affected file silcd/protocol.c.
1269 * Add SKE's reference counter even if calling the completion
1270 callback manually. Otherwise it goes negative, although it
1271 does not cause any problems. The affected file is
1272 lib/silcske/silcske.c.
1274 * Remove the client entry with short timeout after giving the
1275 KILL command. Affected file lib/silcclient/command.c.
1277 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1278 case all found clients are already disconnected (WHOWAS would
1279 found them) in the server. Affected file silcd/command.c.
1281 * Update the last_receive (time of last data received) to be
1282 updated only when received private or channel message so that
1283 the idle time showed in WHOIS makes more sense.
1285 * Added boolean field `valid' in to the SilcClientEntry in the
1286 client library to indicate whether the entry is valid or not.
1287 This fixes the nickname change bug on channel when changing
1288 the nickname to be same than the old (like nick to Nick) the
1289 nickname formatter doesn't set the new nick anymore to Nick@host.
1290 Affected file lib/silcclient/idlist.[ch].
1292 * Now actually fixed the nickname changing on disconnection.
1293 Added new function silc_change_nick to the Irssi SILC Client.
1294 Affected file irssi/src/silc/core/client_ops.c,
1295 irssi/src/silc/core/silc-nicklist.[ch].
1297 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1299 * Check that the public key exists in the GETKEY command before
1300 trying to encode it. Affected file silcd/command.c.
1302 * Print some notifications on received public keys with GETKEY
1303 command in the Irssi SILC Client. Affected files are
1304 irssi/src/fe-common/silc/module-formats.[ch],
1305 irssi/src/silc/core/client_ops.c.
1307 * Use IDENTIFY command to resolve the server information in the
1308 GETKEY command instead of INFO command. Affected file
1309 lib/silcclient/command.c.
1311 * All command reply functions in the client library now calls
1312 the pending command reply callbacks even if an error has
1313 occurred. The server has done this a long time and now it was
1314 time to move the client library to this as well. Now all
1315 errors can be delivered back to the pending command reply
1316 callbacks if necessary. Affected files are
1317 lib/silcclient/command[_reply].[ch].
1319 * Change the nickname on disconnection back to the username
1320 because in reconnect the server will enforce it to it anyway.
1321 Affected file irssi/src/silc/core/silc-servers.c.
1323 * Fixed a config file parsing bug in the Irssi SILC client.
1324 Affected file irssi/src/silc/core/clientconfig.c.
1326 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * When printing the channel mode on JOIN, verify that the
1329 channel key and channel's HMAC are valid. Affected file
1330 irssi/src/silc/core/client_ops.c.
1332 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1334 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1335 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1336 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1338 * Removed channel key rekey task deleting from the function
1339 silc_server_save_channel_key. Affected file silcd/server.c.
1340 Added explicit timeout task context instead that is used to
1341 delete the task if we are registering a new task before the
1342 new task has elapsed.
1344 * When channel key rekey occurs the client library now saves
1345 the old channel key for a short period of time (10 seconds) and
1346 is able to use it in case some is still sending channel
1347 messages encrypted with the old key after the rekey. Affected
1348 file lib/silcclient/[idlist.h|client_channel.c].
1350 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Added check to the silc_server_new_id_real to not accept
1353 new ID if it is the sender's own ID. Affected file is
1354 silcd/packet_receive.c.
1356 * Assure that we do not announce ourself or the one we've
1357 sending our announcements when we're router and are announcing
1358 servers to our primary router. Affected file silcd/server.c.
1360 * Fixed silc_server_command_identify_check_client to assemble
1361 correct WHOIS packet. It send corrupted WHOIS packet and
1362 caused problem with router to router connections. Affected
1363 file silcd/command.c.
1365 Fixed also silc_server_command_whois_check the same way
1366 as for the IDENTIFY command.
1368 * Added new SilcIDListStatus to the server in the SilcIDListData
1369 structure. The status now includes the current status of
1370 the entry (like registered, resolved etc.). Affected file
1371 silcd/idlist.[ch]. Defined a bunch of different status types
1372 as well. This replaced the old boolean registered field as well.
1374 Added resolve_cmd_ident field to the SilcClientEntry structure
1375 too so that if the entry is for example being resolved so
1376 another command may attach to the same pending command reply
1377 without requiring to resolve the same entry again. This concept
1378 should optimize the WHOIS and the IDENTIFY resolving under
1379 heavy load by taking away unnecessary resolving for entries
1380 that are being resolved already.
1382 Added support for adding multiple pending commands for one
1383 command idenfier. Affected file silcd/command[_reply].[ch].
1385 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1386 before deleting the data. Otherwise the hash table will have
1387 freed data in comparison functions. Affected file is
1388 silcd/command_reply.c.
1390 * Fixed silc_idlist_replace_client_id to add the new entry to
1391 the cache with NULL nickname. Otherwise there will be invalid
1392 memory as the nickname after the nickname is freed. Affected
1393 file silcd/packet_receive.c.
1395 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1396 saved into wrong slots because the previous number of entries
1397 was not taken into account. Affected file silcd/idlist.c.
1398 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1400 * If we are router and we receive JOIN notify to a channel that
1401 does not have any users then notified client is marked as the
1402 channel founder, as it is it. The affected file is
1403 silcd/packet_receive.c
1405 * Added to the extended hash table API's table_del_*ext functions
1406 the destructor as argument too, so that the caller can decide
1407 which destructor to use or whether to use destructor at all.
1408 Affected file lib/silcutil/silchashtable.[ch].
1410 * Fixed ID Cache purging. It actually deleted the entries from
1411 the hash table after the data was freed. The hash table ended
1412 up comparing freed memory. The affected file is
1413 lib/silccore/silcidcache.c.
1415 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Fixed Irssi SILC client's KILL command's HELP syntax.
1419 * The USERS command now resolves the detailed user information
1420 if the userinfo field is missing. Affected file is
1421 lib/silcclient/command_reply.c.
1423 * Do not print error in silc_file_read if the read file does
1424 not exist. Just silently return NULL. Affected file is
1425 lib/silcutil/silcutil.c.
1427 * Fixed the silc_log_output to not wine about NULL filename
1428 and to not create some bogus " " filename. Affected file is
1429 lib/silcutil/silclog.c.
1431 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Fixed various printing bugs on the user interface in the
1434 Irssi SILC Client. Minor changes that were forgotten from
1437 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Fixed the configure.in.pre and the compilation and distribution
1440 environment to support the new autoconf 2.52. That version is
1441 now required to compile the CVS trunk.
1443 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1446 to generally parse user@fqdn format strings. Affected file
1447 lib/silcutil/silcutil.c.
1449 * Added nickname_format and nickname_force_format fields to the
1450 SilcClientParams structure. The first one defines the format
1451 for the nicknames that the library will enforce if the receives
1452 multiple same nicknames. The second one is boolean value and
1453 can be used to force the library to always enforce the format
1454 to the nicknames regardles whether there are multiple nicknames
1455 or not. This configurable formatting was employed to flexibly
1456 support accessing multiple nicknames from the user interface.
1457 The userinterface can now set the nicknames to what ever format
1458 they prefer. Affected file lib/silcclient/silcapi.h.
1460 Added function silc_client_nickname_format to the file
1461 lib/silcclient/idlist.c. It performs the nickname formatting.
1463 Added new field `hostname´ to the SilcClientEntry context.
1464 It holds the hostname of the client. Affected file is
1465 lib/silcclient/idlist.h.
1467 * Irssi SILC Client sets the nicknames in nick@hostn format.
1468 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1469 irssi/src/silc/core/silc-core.c.
1471 The WHOIS printing now also shows both the real nickname and
1472 the formatted nickname so that user knows how to access the
1473 user if there are multiple same nicknames cached. Affected
1474 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1475 printing formatting too to take the hostname now as a separate
1476 argument. The Affected file is
1477 irssi/src/fe-common/silc/modules-formats.[ch].
1479 * Changed the silc_client_get_clients_local to accept the formatted
1480 nickname as argument. It accepts the real nickname too but the
1481 formatted nickname can be used to find the true entry from
1482 multiple entries. Affected file lib/silcclient/silcapi.h and
1483 lib/silcclient/idlist.c.
1485 * Added nickname_format_parse field to the SilcClientParams.
1486 It is a callback function provided by the application to parse
1487 the nickname out of the formatted nickname string. The library
1488 calls it to get the nickname from the formatted string. Since
1489 the application generally knows better the format of the nickname
1490 string it parses it instead of the library, even though library
1491 encodes the formatted string. If the callback function is not
1492 provided then the library will use the string as is. The
1493 affected file is lib/silcclient/silcapi.h.
1495 * All the nickname strings passed to the client library in
1496 commands are now expected to be formatted nickname strings.
1497 If the command does not support the formatted nickname string
1498 it will assume that the sent string is the actual nickname.
1499 Affected file lib/silcclient/command.c.
1501 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Added public key authentication support to OPER and SILCOPER
1504 commands in the client library. Affected file is
1505 lib/silcclient/command.c.
1507 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Changed the get_auth_methdod client operation to be asynchronous.
1510 It can be async if the application resolves the authentication
1511 method from the server during the negotiation. Added new
1512 SilcGetAuthMeth completion callback that the application will
1513 call after resolving the authentication method.
1515 Added function silc_client_request_authentication_method that
1516 the application can use to resolve the authentication method
1517 from the server. Added also SilcConnectionAuthRequest callback
1518 that the library will call after the server has replied. The
1519 application can call this function if it does not know the
1520 current authentication method.
1522 Affected files are lib/silcclient/client.c and
1523 lib/silcclient/silcapi.h.
1525 * The Irssi SILC client now automatically resolves the authentication
1526 method incase any configuration information is not present (and
1527 currently there never is). The affected file is
1528 irssi/src/silc/core/client_ops.c.
1530 * Fixed public key authentication from the client library.
1531 Affected file lib/silcclient/protocol.c. Changed also the
1532 protocol specification about the public key authentication in
1533 the connection authentication protocol. The actual data to be
1534 signed is now computed with a hash function before signing.
1536 * Fixed the public key authentication from the server as well.
1537 Affected file silcd/protocol.c.
1539 * Removed the mlock()'s from the memory allocation routines.
1540 Affected file lib/silcutil/silcmemory.c. The ./configure does
1541 not check anymore for the mlock(). Affected file is
1544 * Fixed USERS command in server to allow the execution of the
1545 command for private and secret channels if the client sending
1546 the command is on the channel. Affected file silcd/command.c.
1548 * Fixed silc_client_get_clients_local to return the clients
1549 count correctly. It could return wrong value. Affected file
1550 lib/silcclient/idlist.c.
1552 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1555 types. The assembler optimizations seemed not to like 64-bit
1556 data types. The assmebler optimizations thus are now enabled
1557 also for BSD systems as opposed to only enable them for Linux.
1559 * Do not check for threads at all on BSD systems. Affected
1560 file configure.in.pre.
1562 * Removed -n and -h options from the Irssi SILC Client since
1563 they are not used in silc.
1565 * Fixed the prime generation to assure that the first digit
1566 of the generated random number is not zero since our conversion
1567 routines does not like number strings that starts with zero
1568 digit. If zero digit is seen the random number is regenerated.
1569 This caused some corrupted RSA keys when the zero first digit
1570 was met. Affected file lib/silcmath/silcprimegen.c.
1572 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Fixed WIN32 configuration in the ./configure script.
1575 Fixed to include xti.h on environments that has it.
1576 Patches by Carsten Ilchmann and andrew.
1578 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Changed the silc_id_create_client_id to be collision
1581 resistant. It is now assured that there cannot be created
1582 two same client ID's. I suspect that some weird bugs in
1583 the server were actually caused by duplicate Client IDs.
1584 Affected file silcd/serverid.[ch]. A router receiving
1585 new ID now also assures and informs the sending server
1586 if the ID caused collision.
1588 * Changed the silc_id_create_channel_id to also assure that
1589 there are no collisions.
1591 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Statement about ignoring the Mutual Authentication flag when
1594 performing rekey with PFS was a bit misleading. It is ignored
1595 if it was set in the initial negotiation, it cannot be even
1596 set in the rekey. Fixed in the ke-auth draft. Started the
1597 new versions of the protocol drafts in the doc/.
1599 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Fixed a bug in silc_client_command_identify_save when saving
1602 new channel information. The channel name was no duplicated
1603 and caused crash on exit. Affected file is
1604 lib/silcclient/command_reply.c.
1606 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1608 * Fixed the getkey command handling in the server. Send just
1609 empty OK reply to the sender if the key could not be fetched
1610 (but everything else was ok, like the key just was not available).
1611 Changed the public key parameter to optional in the protocol
1612 specs so that empty OK reply can be sent. Affected file
1615 Added a message to Irssi SILC client to tell to user if the
1616 server did not return a public key.
1618 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Fixed a channel key regeneration bug. It registered new
1621 timeout tasks exponentially until all system resources were
1622 used. Affected file silcd/server.c.
1624 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Added the SILC Document generator to the scripts/silcdoc.
1627 It can be used to generate the Toolkit Reference Manual out
1628 of the source tree. Internally it will also use the RoboDoc
1629 generator now imported in util/robodoc.
1631 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * Added couple of return's in rekey protocol if error orccurred
1634 during the protocol. The execution must be terminated.
1635 Affected file silcd/protocol.c. Also, terminate the protocol
1636 always with timeout.
1638 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * The client's Client ID was created initally from the wrong
1641 nickname (it could have been in format nick@host) in the
1642 silc_server_new_client. Affected file silcd/packet_receive.c
1644 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Added some SILC_LOG_ERROR's to various error conditions
1647 if client could not be added to ID cache. Affected files
1648 silcd/packet_receive.c and silcd/server.c.
1650 * When client's sock->user_data is freed, NULL also the
1651 client->router and client->connection pointers. Added check
1652 for these pointers being NULL to various places around the
1653 code. Affected file silcd/server.c.
1655 * Added client->data.registered == TRUE checks to various
1656 places around the code to assure that unregistered client's
1657 are not handled when it is not allowed. Affected file
1660 * Added `bool registered' fields to all
1661 silc_idlist_[server|client]_get_* routines to indicate whether
1662 the fetched client needs to be registered or not. Affected
1663 file silcd/idlist.[ch].
1665 * Add your own entry as registered to the ID cache in the
1666 server. Affected file server.c.
1668 * Fixed a bug in silc_server_new_server. The SilcServer was
1669 set as the new server's context instead of SilcServerEntry.
1670 This naturally caused some weird bugs.
1672 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Do not delete the channel rekey task when adding it
1675 for in silc_server_create_channel_key.
1677 * Changed the silc_server_create_channel_key to return
1678 TRUE or FALSE to indicate the success of the channel key
1681 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Fixed MSVC++ project files and added missing files to

1692 * Fixed buffer overflow from Irssi SILC Client. Affected
1693 file irssi/src/fe-common/core/themes.c.
1695 * Fixed double free in client library in the file
1696 lib/silcclient/client.c when disconnecting from server.
1698 * Applied double free patch from cras to Irssi SILC client.
1699 Affected files irssi/src/core/[modules/expandos].c
1701 * Fixed the disconnection handling to Irssi SILC Client.
1702 The application must call silc_client_close_connection
1703 in ops->connect client operation in case of failure of
1704 the connection. Affected file is
1705 irssi/src/silc/core/client_ops.c.
1707 * Do not set sock->protocol to NULL in the function
1708 silc_client_close_connection after executing the protocol's
1709 final callback since the sock might not be valid anymore.
1710 Affected file lib/silcclient/client.c.
1712 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Do not enable SILC_THREADS if the linking with libpthread
1715 did not happen. Affected file configure.in.pre.
1717 * Added notion to protocol specification that server must
1718 verify the sent authentication payload with CMODE when
1719 setting the channel founder key. Implemented it to the
1720 server. Affected file silcd/command.c.
1722 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Added _EXTRA_DIST SILC distribution variable to the
1725 distributions file. It is used to conditionally add extra
1726 files or directories to the specific distribution. Affected
1727 files ./prepare, Makefile.am.pre and distributions.
1729 Removed the `_' from the start of the distribution names.
1732 * Added README.WIN32 for instructions to compile the Toolkit
1735 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * Fixed a double free in disconnection in the server. Affected
1738 file is silcd/server.c.
1740 * Fixed the lib/silcske/groups.c to work now also with GMP
1741 MP library. The string conversion did not work when using
1742 specific base and the base is indicated in the string as well.
1744 * Created win32/ directory which now includes MSVC++ specific
1745 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1746 It will appear only in the toolkit distribution
1748 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Changed the key material distribution function in case when
1751 the hash output is too short. The data is now concatenated
1752 a bit differently than it used to. Made the change to the
1753 SKE protocol specification.
1755 * Added better GMP detection to configure.in.pre. A patch
1758 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Fixed a minor bug in SKE that might cause some problem on
1761 some platforms. Affected file lib/silcske/silcske.c.
1763 * Added the cookie checking for initiator in the SKE. It checks
1764 that the responder returns the sent cookie unmodified. The
1765 affected file is lib/silcske/silcske.c. Added new SKE
1766 error type INVALID_COOKIE that can be sent during the
1767 negotiation. Fixed some memory leaks as well.
1769 * Added the "invalid cookie" error message to Irssi SILC client's
1772 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Added `task_max' field to the SilcClientParams to indicate
1775 the maximum tasks the scheduler can handle. If set to zero,
1776 default values are used. Affected file lib/silcclient/silcapi.h.
1778 * Fixed memory leaks in silc_client_close_connection. Affected
1779 file lib/silcclient/client.c.
1781 * Added silc_client_del_client_entry to client library to free
1782 all memory of given client entry. Affected file is
1783 lib/silcclient/idlist.[ch].
1785 * Added new functions silc_client_del_channel and
1786 silc_client_del_server to delete channel and server entries.
1787 Affected file lib/silcclient/[silcapi.h/idlist.c].
1789 * Removed silc_client_del_client_by_id from silcapi.h.
1791 * Fixed the INFO command to return the server's own info
1792 correctly when querying by Server ID. Affected file is
1795 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Removed the non-blocking settings in WIN32 code in the
1798 silc_sock_[read/write] and added SleepEx instead. Affected
1799 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1800 of input data is now checked with FIONREAD and ioctlsocket.
1802 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Call silc_schedule_task_del_by_context in the
1805 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1806 Affected file lib/silccore/silcprotocol.c.
1808 * Call silc_protocol_cancel for active protocols in the
1809 silc_server_close_connection if the funtion
1810 silc_server_free_sock_user_data has not been called.
1811 Affected file silcd/server.c.
1813 * Generic tasks cannot be deleted using the del_by_fd
1814 task deleting function since generic tasks does not match
1815 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1817 * Added a notion to SILCOPER help file that the SILCOPER works
1818 only on router server, not on normal server.
1820 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Added for WIN32 support for the new scheduler as well.
1823 Affected file lib/silcutil/win32/silcwin32schedule.c.
1825 * Fixed the SHA1 implementation to work on various platforms.
1827 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1830 API. It is part of the scheduler now. Everything else is
1831 as previously but some functions has changed their names.
1832 Checkout the lib/silcutil/silcschedule.h for the interface.
1833 Updated all applications to use the new interface. Affected
1834 files are lib/silcutil/silcschedule.[ch].
1836 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Found a bug in the SKE implementation. The HASH value,
1839 specified by the protocol, was not computed correctly. The
1840 public key of the responder was not added to the computation
1841 even though it is mandatory. Affected file lib/silcske/silcske.c.
1842 This unfortunately causes incompatibilities with older
1843 clients and servers.
1845 * Added WIN32 specific network init and uninit functions:
1846 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1847 the Winsock2. Affected file lib/silcutil/silcnet.h and
1848 lib/silcutil/win32/silcwin32net.c.
1850 * Set the socket always to nonblocking mode on WIN32 after
1851 reading data or writing data. Affected file is
1852 lib/silcutil/win32/silcwin32sockconn.c.
1854 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed various compilation problems under WIN32. Affected
1857 files lib/silcutil/win32/silcwin32thread.c and
1858 lib/silcutil/win32/silcwin32schedule.c.
1860 * Removed all _internal.h #includes from public header
1861 files. Internal headers must never be included from
1864 Removed also the lib/silcske/payload_internal.h file.
1866 * All include files that may be needed (public and some others
1867 included by the public headers) by application developers are
1868 now copied to the ./includes directory. It does not copy any
1869 internal headers. Affected file Makefile.defines.pre and all
1870 Makefile.am's under lib/ and subdirs.
1872 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Do not change the ~/.silc directory's permissions automatically.
1875 Affected file irssi/src/silc/core/clientutil.c.
1877 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Do not cancel the protocol in silc_server_close_connection
1880 it might cause recursion. Now cancelled in the function
1881 silc_server_free_sock_user_data. Affected file silcd/server.c.
1883 * Fixed the silc_server_remove_clients_by_server to regenerate
1884 the channel keys correctly finally. Added also new function
1885 silc_server_remove_clients_channels to actually do it.
1886 Affected file silcd/server.c.
1888 * Fixed the silc_server_new_channel to not crash by giving
1889 wrong router to the new channel. Affected file is
1890 silcd/packet_receive.c.
1892 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1895 which is given as argument to the silc_client_alloc now.
1896 It can be used to configure the client and set various parameters
1897 that affect the function of the client.
1899 * The USERS command in server did not check whether the channel
1900 is private or secret. Affected file silcd/command.c.
1902 * Added new argument to the USERS command in protocol specification.
1903 The USERS command now can take the channel name as argument
1904 as well. Added support for this in client and server and
1905 updated the protocol specs.
1907 * Completed the GETKEY command in client. It can be now used
1908 to fetch also servers public key not only some clients.
1909 Affected files lib/silcclient/command[_reply].c.
1911 * Added silc_client_get_server to return server entry by the
1912 server name. Affected files lib/silcclient/silcapi.h and
1915 * Redefined the IDENTIFY command in protocol specification to be
1916 more generic. It now can be used to query information about
1917 any entity in the SILC Network, including clients, servers and
1918 channels. The query may be based either the entity's name
1919 or the ID. Added support for this in both client and server.
1921 Affected files silcd/command.c and lib/silcclient/command.c
1922 and command_reply.c.
1924 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1925 the _from_client and _from_server functions. Affected file
1928 * Added silc_client_get_channel_by_id_resolve to the file
1929 lib/silcclient/silcapi.h to resolve channel information by
1930 its ID. Added also silc_client_get_channel_by_id that
1931 does not resolve it from the server.
1933 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Added SilcServerEntry context into the client library
1936 to represent one server. The INFO command now allocates
1937 these to save the resolved server info. For now on the
1938 client library will also keep information about servers,
1939 connected and resolved with INFO.
1941 The INFO command now allocates the SilcServerEntry context
1942 and saves the server info there. The COMMAND_REPLY in
1943 the INFO now returns the parameters to application in
1944 same order as defined in the protocol specification.
1946 The entries are cached in the client->server_cache.
1948 * The INFO command is now issued after received the Client ID
1949 from the server. Affected file lib/silcclient/client.c.
1951 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1952 to the application as the mode changer might be server.
1953 It is guaranteed that NULL is not returned anymore to the
1954 application. Affected file lib/silcclient/client_notify.c.
1956 The ID Type is now also passed to the application so that
1957 it can check whether the returned entry is SilcClientEntry
1960 Added new function silc_client_get_server_by_id to return
1961 the server entry by ID. Affected files are the
1962 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1964 * Do not create the channel in the Irssi SILC Client when issuing
1965 the JOIN command but when received the sucessful JOIN command
1966 reply. Otherwise the channel might get created even though we
1967 could not join it. The Affected file is
1968 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1970 * Fixed a channel joining bug in router. The router must also
1971 check the channel modes, invite and ban lists etc. when serving
1972 the JOIN command sent by normal server. Affected file is
1973 silcd/command.c. The router now resolves the client's
1974 information from the server who sent the JOIN command if it
1975 does not know it, and processes the JOIN command only after
1978 * Changed the SilcCommandCb to take new argument; void *context2.
1979 Affected file lib/silccore/silccommand.h
1981 The second argument in the command callbacks in the server now
1982 includes the SilcServerCommandReplyContext if the command was
1983 called as pending command callback from the command reply.
1984 Otherwise it is NULL. When called as pending the status of the
1985 command reply will be checked and if it was erronous the
1986 error will be sent to the original sender of the command.
1987 This way the client always receives the error messages even
1988 though the server was actually the one who received the error
1989 when it resent the command to router, for example. Affected
1990 files silcd/command[_reply].[ch].
1992 * Fixed sending WHOWAS command's error message to client if
1993 the requested client could not be found. It was missing.
1996 * Changed the CMODE and CUMODE commands reply arguments in the
1997 protocol specification. The Channel ID is now sent in both
1998 of the commands to identify the channel. Implemented this
1999 new feature to the client and server. Affected files
2000 lib/silcclient/command_reply.c and silcd/command.c.
2002 * Made better checks for invite and ban lists in the JOIN
2003 command in server. Affected file silcd/command.c.
2005 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * The server now performs the incoming host IP/DNS lookup
2008 using the silc_socket_host_lookup and thus does not block
2009 the server anymore. Affected file silcd/server.c.
2011 * Completed the multi-thread support for SILC Scheduler in
2012 the lib/silcutil/silcschedule.c.
2014 * Fixed the configure.in.pre to detect the pthread correctly
2017 * Fixed a deadlock in silc_task_queue_wakeup in the file
2018 lib/silcutil/silctask.c.
2020 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Added new function silc_schedule_wakeup that is used in
2023 multi-threaded environment to wakeup the main thread's
2024 schduler. It needs to be used when a thread adds a new task
2025 or removes a task from task queues. After waking up, the
2026 scheduler will detect the task queue changes. If threads
2027 support is not compiled in this function has no effect.
2028 Implemented the wakeup mechanism to both Unix and WIN32
2029 systems. Affected files are lib/silcutil/silcschedule.[ch],
2030 lib/silcutil/unix/silcunixschedule.c and the
2031 lib/silcutil/win32/silcwin32schedule.c.
2033 * Added new function silc_task_queue_wakeup to wakeup the
2034 scheduler by the specified task queue. Affected file
2035 lib/silcutil/silctask.[ch].
2037 * The silc_socket_host_lookup_start now wakes up the scheduler
2038 after adding the timeout task. Affected file is
2039 lib/silcutil/silcsockconn.c.
2041 * The silc_socket_host_lookup is synchronous now if the threads
2042 support is not compiled in. However, the callback is still
2043 called asyncronously through the scheduler, anyway. Affected
2044 file lib/silcutil/silcsockconn.c.
2046 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Added new function silc_socket_host_lookup to perform
2049 asynchronous IP and FQDN lookups for the socket connection.
2050 Affected files lib/silcutil/silcsockconn.[ch].
2052 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2055 that may or may not compile the mutex support in.
2057 Changed the silc_mutex_alloc interface. It allocates the
2058 mutex now to the sent pointer and returns TRUE or FALSE.
2060 Affected file lib/silcutil/silcmutex.h.
2062 * Wrote the SILC Task Queue interface to support multi-threads.
2063 Affected file lib/silcutil/silctask.[ch].
2065 * Wrote the SILC Scheduler to support multi-threads. Affected
2066 file lib/silcutil/silcschedule.c.
2068 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2071 in lib/silcutil/win32/.
2073 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Defined SILC Mutex API and SILC Thread API and implemented
2076 them for Unix. Affected files are
2077 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2078 lib/silcutil/unix/silcunixmutex.c and
2079 lib/silcutil/unix/silcunixthread.c.
2081 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Fixed the silc_server_remove_clients_by_server's channel
2084 key re-generation. The hash table handling was incorrect
2085 and would not work with many channels. Affected file is
2088 * Fixed some memory leaks around the server code.
2090 * Rewrote the silc_server_get_users_on_channel to support IPv6
2091 based Client ID's. Affected file silcd/server.c.
2093 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2094 specification. However, a separate document must be written
2095 to define the detailed signing procedure and the payload
2096 associated with the flag. Defined the flag to the
2097 lib/silccore/silcchannel.h as well.
2099 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Changed the dynamic tables to static size tables in the
2102 lib/silccrypt/silchmac.c.
2104 * Removed GCC dependencies from the code. A patch by cras.
2106 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Do not show the error "Error receiving packet bla bla"
2109 in server if it really was not an error (-2 means that reading
2110 is pending). Affected file silcd/server.c.
2112 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Fixed a possible crash in silc_server_remove_clients_by_server
2115 in silcd/server.c. Fixed there also some memory leaks.
2117 * Fixed the silc_idlist_replace_client_id. It could replace
2118 wrong key in the hash table. Affected file silcd/idlist.c.
2120 * Do not check whether there are global users on the channel
2121 if the channel->global_users is FALSE. Affected functions
2122 silc_server_remove_from_one_channel and
2123 silc_server_remove_from_channels in silcd/server.c. Also,
2124 do not check if the removed client is local as we can be
2125 sure that global client was not removed from the channel
2126 and checking for global users is not needed.
2128 * The silc_server_remove_clients_by_server now re-generates
2129 the channel keys correctly for those channels that had
2130 clients removed from them. Affected file silcd/server.c.
2132 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Found the reason of random crashes in the server. We weren't
2135 ignoring the SIGPIPE signal (which can be sent in write())
2136 and it crashed the server. Affected file silcd/silcd.c.
2138 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Assure that sock->user_data is not NULL in the function
2141 silc_server_packet_send in silcd/packet_send.c.
2143 * Disconnect the remote connection if it could not be added
2144 to any ID lists in the server. The affected file is
2147 * Check in silc_server_packet_send[_real/dest] that the
2148 socket is not disconnecting and ignore the data if it is.
2149 Affected file silcd/packet_send.c.
2151 * Define inline to __inline on native WIN32 compilation.
2152 Affected file includes/silcwin32.h.
2154 * Added some explicit type casts for inline code since MSVC
2155 require them. Affected files lib/silcutil/silcbuffer.h,
2156 lib/trq/silcdlist.h and lib/trq/silclist.h.
2158 * Print warning in log files from now on if the packet
2159 decryption fails. Affected file silcd/server.c.
2161 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Changed the `say' client operation's interface to accept
2164 new `type' argument to indicate the type of the message sent
2165 by the library. The application may filter the library's
2166 messages according the type. The affected file is the
2167 lib/silcclient/silcapi.h.
2169 * Added two new functions to lib/silcclient/silcapi.h:
2170 silc_client_del_client and silc_client_del_client_by_id.
2171 Affected file lib/silcclient/idlist.c.
2173 * Moved the clientincludes.h from includes/ to silc/ and
2174 serverincludes.h from includes/ to silcd/.
2176 * The modes for the CMODE and CUMODE are now passed as
2177 uint32 for application with COMMAND_REPLY. The affected
2178 file is lib/silcclient/command_reply.c.
2180 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * /WHOIS without arguments shows client's own information.
2183 Affected file lib/silcclient/command.c.
2185 * Changed PING to not accept any arguments. The specs
2186 says that client can ping only the connected server so
2187 requiring an argument is not needed. Affected file is
2188 lib/silcclient/command.c.
2190 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Fixed a fatal bug in private message sending and reception
2193 encryption and decryption when using private message keys.
2194 The implementation was incorrect and did not follow the
2195 specification. It causd that some of the message were
2196 lost since it did not use the sending and receiving keys
2197 as the protocol suggests. This has been fixed and will cause
2198 incompatibilities with older clients when sending private
2199 message encrypted with private message keys. Affected files
2200 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2201 and various other in Irssi SILC Client.
2203 Added `responder' boolean argument to the functions
2204 silc_client_add_private_message_key[_ske] to indicate when
2205 the key is added as responder or initiator of the key
2208 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Removed the silc_ske_check_version function and created
2211 a SilcSKECheckVersion callback. Added also a function
2212 silc_ske_set_callbacks that is now used to set all SKE
2213 callbacks. The callback functions are not given to
2214 the SKE functions anymore, but this function is used to
2217 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2219 * Added `silc_version' argument to the silc_client_alloc
2220 to define the version of the application for the library.
2221 The library will use the version string to compare it
2222 against the remote host's (usually a server) version
2223 string. Affected file lib/silcclient/silcapi.h
2225 * Added the KE protocol context to Key Agreement context
2226 in client library so that we can abort the SKE if it
2227 is in process when we get timeout. Affected file is
2228 lib/silcclient/client_keyagr.c.
2230 * Do not resolve the client ID forever if it returns in the
2231 first time that such client does not exist. This was done
2232 for example with private message. Affected file is
2233 lib/silcclient/client_prvmsg.c.
2235 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Do not add regex.h for WIN32. The affected file
2238 includes/silcincludes.h.
2240 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2241 not work yet 100%. It generates the DLL's automatically
2242 when compiling with --with-win32 under cygwin.
2244 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * lib/contrib/regex.c is not compiled on WIN32.
2248 * Added silc_net_get_socket_opt function to the
2249 lib/silcutil/silcnet.h.
2251 * Added includes/silcwin32.h for WIN32 specific includes
2254 * Do not use ptime structure or any of the posix process
2255 functions on WIN32 in lib/silccrypt/silrng.c.
2257 * Added silc_gettimeofday to provide generic function
2258 for struct timeval on all platforms. Added the function
2259 to lib/silcutil/silcutil.h.
2261 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2264 library as they clearly belong there. As a plus side we
2265 can make the actual socket connection routines platform
2268 Added also new generic function silc_socket_read and
2269 silc_socket_write (that used to be silc_packet_[read/write].
2270 The implementation of these are platform specific.
2272 * Added WIN32 specific routines of silc_socket_[read/write]
2273 to lib/silcutil/win32/silcwin32sockconn.c.
2275 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Added preliminary support for native WIN32 compilation under
2278 cygwin (using the -mno-cygwin option for GCC) to the
2279 ./configure.in.pre. The --with-win32 now prepares the
2280 compilation for native WIN32.
2282 * Rewrote the SILC Scheduler interface in the file
2283 lib/silcutil/silcschedule.h. The scheduler is now context
2284 based and does not have anymore any global static scheduler.
2285 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2286 and created lib/silcutil/win32 directory for WIN32 based
2289 * Added Unix specific network routines to the
2290 lib/silcutil/unix/silcunixnet.c and the old
2291 lib/silcutil/silcnet.c includes now only generic routines.
2293 Added WIN32 specific network routines to the
2294 lib/silcutil/win32/silcwin32net.c.
2296 * Added Unix specific utility functions from the
2297 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2299 * Added WIN32 SILC Scheduler to the file
2300 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2303 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Do not handle JOIN notify in the server if the target client
2306 is not registered (idata->registered == FALSE). The affected
2307 file is silcd/packet_receive.c.
2309 * Update the nickrec->founder in event_cumode in the Irssi SILC
2310 client. Affected file irssi/src/silc/core/silc-channels.c.
2312 * Fixed the CUMODE_CHANGE notify handling in the server when
2313 server and router are announcing their clients on channels.
2314 Now the mode changes are saved and notified correctly. The
2315 affected file is /silcd/packet_receive.c.
2317 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2318 They really did not replace the cache entry in the ID Cache.
2319 Now they do that. Affected file silcd/idlist.c.
2321 * Fixed the KICK notify handling in the Irssi SILC client to
2322 update the channel records so that the kicked client does not
2323 appear to be on the channel. The affected file is
2324 irssi/src/silc/core/silc-channels.c.
2326 * Always update the conn->current_channel when executing command
2327 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2329 * Fixed the KILL notify handling in Irssi SILC client to remove
2330 the killed client on all channels.
2332 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Fixed the silc_parse_command_line to remove extra spaces
2335 from the start and end of the arguments. Affected file is
2336 lib/silcutil/silcutil.c.
2338 * Cancel and free any active protocol in the function
2339 silc_server_close_connection. Affected file silcd/server.c.
2341 * Cancel and free any active protocol in the function
2342 silc_client_close_connction. Affected file is
2343 lib/silcclient/client.c.
2345 * Do not execute the KILL command for clients that are in
2346 history (ie. they are not in the network). Affected file is
2349 * Fixed KILL notify handling, client does not crash anymore.
2350 Affected file irssi/src/silc/core/silc-channels.c.
2352 * Reduced the default packet buffer size from 2048 to 1024 in
2353 lib/silccore/silcpacket.c.
2355 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2356 counter to the SKE context that is incresed when the SKE library
2357 performs async operation outside the library. If the outside
2358 process frees the SKE context and FREED status will be set
2359 and the library will detect after the sync operation that the
2360 libary is freed. The affected files are
2361 lib/silcske/silcske[_status].[ch].
2363 * Resolve the client entry information in the function
2364 silc_client_channel_message to assure that NULL pointer is not
2365 passed as client entry to the application. */
2367 * Fixed the task timeout calculation to assure that there is
2368 never negative timeouts. The affected file is
2369 lib/silcutil/silcschedule.c.
2371 * Fixed the channel user mode notification sending in server.
2372 It was sent point-to-point to the router (or to server by router)
2373 but it needs to be destined to a channel. The routines now
2374 supports sending the channel user mode notifys to the channels
2375 when announcing clients and channels. Affected files are
2376 silcd/server.c and silcd/packet_receive.c.
2378 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2379 It did not actually replace the old channel entry in the cache.
2380 Affected file lib/silcclient/client_notify.c.
2382 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Fixed a possible crash in silc_packet_send_prepare. It now
2385 assures always that there is enough space in the buffer and
2386 at the tail area of the buffer (for MAC).
2388 Fixed the inbound buffer reallocation in silc_packet_read.
2389 It was old code and did not handle the reallocation correctly.
2392 The affected file is lib/silccore/silcpacket.c.
2394 * Fixed buffer overflow in silc_parse_nickname in the file
2395 lib/silcutil/silcutil.c.
2397 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * make install generates new server keys only if there is not
2402 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2405 Added check that if the NOREPLY is set then we will not send
2406 the away message. This avoids infinite loop of away messages
2407 if both clients are away. The affected file is
2408 lib/silcclient/client_prvmsg.c.
2410 * Fixed client crash if /NICK was given without arguments.
2411 Affected file lib/silcclient/command.c.
2413 * Server does not send the invite list in INVITE command back
2414 to the client if the list was not altered. Added this notion
2415 to the protocol spec as well. Affected file silcd/command.c.
2417 Fixed possible crash in INVITE command by checking the
2418 value of silc_server_get_client_route command.
2420 * Fixed the INVITE notify type handling. The arguments are now
2421 taken in correct order and client does not crash. The affected
2422 file is irssi/src/silc/core/silc-channels.c.
2424 Removed the "Inviting xxx to channel" message from the
2425 client library away and let the application handle it.
2426 Affected file lib/silcclient/command.c. Added that message
2427 to Irssi SILC client's message formats.
2429 * Fixed CMODE command crash in client. It now checks the
2430 amount of arguments correctly and does not crash. The affected
2431 file is lib/silcclient/command.c.
2433 * Do not create new channel automatically in silc_channels_join
2434 but check whether the channel by that name already exists.
2435 Affected file irssi/silc/core/silc-channels.c.
2437 * Do not send the SERVER_SIGNOFF to router if the disconnected
2438 entity was the router. Affected file silcd/server.c.
2440 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2441 SILC client as it was missing from there.
2443 Added the handling of the KICK notify to the Irssi SILC client
2444 as it was missing. Added "you have been kicked" message to
2445 Irssi SILC client's message modules formats.
2447 Added the handing of the KILL notify to the Irssi SILC client
2448 as it was missing. Added the kill message module formats
2451 The affected file is irssi/src/silc/core/silc-channels.c.
2453 * The router did not save the channel mode the server announced.
2454 Affected file silcd/packet_receive.c.
2456 * Fixed a possible crash in INFO command in server. If the
2457 server did not provide the server info it crashed. Affected
2458 file silcd/command.c.
2460 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Fixed the GETKEY command in the server to check also the
2463 global list. Otherwise the GETKEY would not work correctly
2464 in normal SILC server. Affected file silcd/command.c.
2466 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Fixed GETKEY crash, it crashed if the command did not succseed.
2470 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2473 is now real and not just an macro interface to GMP.
2475 Removed the entire GMP from the source tree and imported new
2476 NSS MPI library instead. Reason for removing GMP is that it is
2477 extremely large and compiles extremely slow. The NSS MPI
2478 is only a few files and compiles in less than 10 seconds.
2479 The speed is also about the same as GMP. The MPI is imported
2480 to lib/silcmath/mpi.
2482 If the system has GMP installed we will still use the GMP.
2483 If it is not then the NSS MPI will be compiled.
2485 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Merged a long nickname (127 characters long) crash bugfix from
2488 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2490 * Merged a freed memory reference bugfix from Irssi CVS tree.
2491 Affected file irssi/src/core/commands.c.
2493 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2495 * Added the server's public key sving and verification to the
2496 server when performing the SKE. This was missing and the
2497 remote server's (or router's) public key was accepted without
2498 checking whether we have it previously or trust it at all.
2499 Affected file silcd/protocol.c.
2501 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2503 * Check in the silc_server_timeout_remote if protocol is active
2504 and make sure that the protocol's final callback is called so
2505 that all memory if freed. Affected file silcd/server.c.
2507 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2509 * silc_server_whois_send_reply crashed the server if the nickname
2510 was 127 characters long. Affected file silcd/command.c.
2512 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added sanity check to the silc_server_new_client. If the hostname
2515 is provided inside username then check that the provided hostname
2516 really is the same as the resolved one. If the hostname was not
2517 resolved then check it from the public key. Affected file is
2518 silcd/packet_receive.c.
2520 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2521 if the server disconnected us and the connection is not valid
2522 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2524 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2525 the library to the lib/silcutil/silcutil.[ch].
2527 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2529 * Close log file after open. Affected file
2530 lib/silcutil/silclog.c.
2532 * Check whether sock == NULL in silc_client_send_packet and return
2533 if it is. Affected file lib/silcclient/silcclient.c.
2535 * Check rec->entry == NULL in the Irssi SILC Client before
2536 sending the channel message. Affecte file is
2537 irssi/src/silc/core/silc-servers.c.
2539 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2541 * Merged a splitted window bugfix from Irssi CVS tree. The
2542 affected file is irssi/src/fe-text/textbuffer-view.c.
2544 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2545 It did not print nickname.
2547 * Improved the distributions system a bit.
2549 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2552 irssi/src/fe-text/gui-window.c.
2554 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2555 to in-active server. The affected file is
2556 irssi/src/silc/core/client_ops.c.
2558 * Resolve the client in USERS command reply if the entry does
2559 not have username resolved. The affected file is
2560 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2561 command to WHOIS command to really resolve stuff. The USERS
2562 is not used any more in any critical section so WHOIS can
2563 be used even though it might be slower than IDENTIFY.
2565 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2568 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2570 * Changed the protocol API a bit more consistent in the
2571 lib/silccore/silcprotocol.[ch].
2573 * Changed the following headers to ROBODoc format:
2575 lib/silccore/silcpayload.h
2576 lib/silccore/silcprotocol.h
2577 lib/silccore/silcsockconn.h
2579 All core library headers are now formatted.
2581 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Fixed a bug in Irssi SILC client; do not show that you are
2584 server/router operator if you really are not. Affected file is
2585 irssi/src/silc/core/client_ops.c.
2587 * Renamed silc_command_free_payload to silc_command_payload_free.
2588 Affected file lib/silccore/silccommand.h
2590 * Added silcmath.h to include the prototoypes of various routines
2591 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2594 * Changed the following headers to ROBODoc format:
2596 lib/silccore/silcchannel.h
2597 lib/silccore/silccommand.h
2598 lib/silccore/silcid.h
2599 lib/silccore/silcidcache.h
2600 lib/silccore/silcmode.h
2601 lib/silccore/silcnotify.h
2602 lib/silccore/silcpacket.h
2603 lib/silcmath/silcmath.h
2605 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Added checking to the server code not to start the server if
2608 ciphers and stuff are not configured properly. Affected files
2609 silcd/serverconfig.[h] and silcd/server.c.
2611 * Changed the layout of the header files of the public interfaces
2612 in the SILC libraries. The new layout supports ROBODoc
2613 documentation tool (and some others) so that it is easy to create
2614 a library reference manual. All the other headers and source
2615 code must still follow the CodingStyle document. Also source
2616 code must not include these ROBODoc stuffs, only the headers.
2617 Furthermore, all public interface headers must now be named
2618 by using `silc' prefix, example: silcapi.h, silccipher.h.
2619 Some files were renamed due to this. All the other headers
2620 must not be used as public interfaces. I will update the
2621 CodingStyle document later. Changed following headers, so far:
2623 lib/silcclient/silcapi.h
2624 lib/silccore/silcauth.h
2625 lib/silccore/silcprivate.h
2626 lib/silccrypt/silcdh.h
2628 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Removed silc_client_packet_send_flush from the client library
2633 as it is not needed. Affected file lib/silcclient/client.[ch].
2635 * Added printing of message of unresolved authentication method
2636 to the Irssi SILC client. Added it to the module formats.
2637 Removed the same message from the client library.
2639 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2641 * Added new distribution feature, DISTLABEL. Every distribution
2642 can define own preprocessor label that can be used in the
2643 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2644 file distributions, acconfig.h.pre and prepare.
2646 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Added Makefile.defines_int to include the actual definitions
2649 for Makefile.defines.in. Tested the new distribution system,
2650 created distributions and tested installation.
2652 * Added AWAY message printing to the Irssi SILC client. Added
2653 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2655 * Added SCONNECT command to call the SILC's CONNECT command.
2656 Cannot use CONNECT directly since Irssi uses that internally.
2657 Affected file irssi/src/silc/core/silc-servers.c.
2659 Added ACTION local command. It is same as ME command but takes
2660 the channel as mandatory argument.
2662 Rewrote some of the Irssi's help files to suite for SILC
2665 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Added Makefile.defines[.in] that should for now on be included
2668 in all Makefile.am file in the source tree. That file includes
2669 all common compilation definitions for SILC source tree.
2671 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Minor changes to the ./prepare script to change the package
2674 name according the distribution name to the configure.in.
2676 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Created new distribution system. Added file `distributions'
2679 that defines all the distributions that can be created out of
2680 the SILC source tree. The ./prepare script now reads that
2681 file to determine how to prepare the distributions. The
2682 first argument to the ./prepare is the name of the distribution
2683 and second is the version of the distribution. If given
2684 without arguments it creates the default (toolkit) distribution
2685 with the default version (defined in ./prepare).
2687 All Makefile.am files that are subject to the distributions
2688 are now named as Makefile.am.pre. These are ./Makefile.am
2689 and lib/Makefile.am. Others may be changed later.
2691 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Added invite list, ban list, some key management and connection
2694 error message printing to module formats in the Irssi SILC client.
2696 * Added new silc_client_set_away_message to set the away message
2697 that is back to the person who sent private message. The
2698 affected file lib/silcclient/silcapi.h and the
2699 lib/silcclient/client_prvmsg.c.
2701 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2703 * Fixed the private message sending in the Irssi SILC client,
2704 added local command KEY to the Irssi SILC client.
2706 Added key management and key agreement message formats to the
2707 irssi/src/fe-common/silc/module-formats.[ch].
2709 Added USERS (alias WHO) printing, server/router operator
2710 indication and LIST command printing to the module formats.
2712 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Fixed channel joining notify handling, cumode notify handling
2715 from Irssi SILC client.
2717 * Added SILC specific module-formats to the Irssi SILC client so
2718 that SILC specific message hilighting, colors etc is possible.
2719 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2721 Added channel mode, channel user mode, actions, notices,
2722 whois and whowas printing to the the module-formats.c.
2724 * Fixed a bug in channel deletion in the server. The channel
2725 is not left to the cache even if the channel founder auth mode
2726 is set when there are no users anymore on the channel. Affected
2727 file silcd/server.c.
2729 * The silc_net_localhost now resolves the entire hostname including
2730 the domain name. Affected file lib/silcutil/silcnet.c.
2732 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Changed the ask_passphrase client operation to be ascynchronous.
2735 It has now a completion callback and a context that the
2736 application must call after it has got the passphrase from
2737 the user. Affected files lib/silcclient/silcapi.h,
2738 lib/silcclient/protocol.c, lib/silcclient/command.c and
2741 Added SilcAskPassphrase callback that the application calls
2742 to deliver the passphrase to the library.
2744 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2745 The public key verification and especially a certificate
2746 verification is asynchronous procedure.
2748 Added new SILC_SKE_STATUS_PENDING status to indicate the
2749 request is pending and a callback will be called to finalize
2752 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2753 indicate that remote end did not send its public key (or
2754 certificate), even though we require it. Added check for this
2755 condition in the SKE. This was a security bug, now fixed.
2757 Defined new SilcSKEVerifyCbCompletion callback that is called
2758 when the verification process is completed.
2760 The affected files lib/silcske/silcske_status.h and
2761 lib/silcske/silcske.[ch].
2763 * Changed the verify_public_key client operation to be async
2764 as well. Defined SilcVerifyPublicKey callback that is used to
2765 indicate the success of the public key verification process.
2767 Changed the server and client to use the new async client
2770 * Changed the Irssi SILC client's internal scheduler to be called
2771 twice as many times as it used to be. As a result the client
2772 should be a bit faster now. Affected file is
2773 irssi/src/silc/core/silc-core.c.
2775 * Added support to Irssi SILC client of asynchronous public key
2776 verification and passphrase inquiry. Affected file is
2777 irssi/src/silc/core/silc-core.c.
2779 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2781 * Do not say "You have left channel %s" in client library.
2782 Moved it to the application. Affected files are
2783 lib/silcclient/command.c and silc/client_ops.c.
2785 * Fixed silc_client_get_clients. Command context was not
2786 duplicated and was freed memory in the callback. Affected
2787 file lib/silcclient/idlist.c.
2789 * Do not say "you are now talking..." on JOIN command in the
2790 client library. The appliation must handle it.
2792 * Do not say ".. changed topic to" in command reply in the
2793 client libary. The application must handle it.
2795 * Fixed TOPIC command sending in the client library.
2797 * Fixed a memory leak in silc_client_command_free in the file
2798 lib/silcclient/command.c.
2800 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2802 * Imported a modified version of Irssi client to the source tree.
2803 The Irssi will be used to create a new client called
2804 Irssi SILC. Imported to irssi/.
2806 Added silc_core_init_finish function to the Irssi. Affected
2807 file irssi/configure.in.
2809 A lot changes in the Makefile.ams around the irssi tree.
2811 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Do not rehash if the new size is same as the old size of the
2814 hash table, in the silc_hash_table_rehash*. The affected file
2815 lib/silcutil/silchashtable.c.
2817 * Replaced hash_table_del_by_context calls from the server
2818 (when channel->user_list and client->channels) to the
2819 hash_table_del as it is sufficient and faster.
2821 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Added silc_hash_table_list, silc_hash_table_get and the
2824 SilcHashTableList structure to provide an alternative way to
2825 traverse the hash table. The affected files are
2826 lib/silcutil/silchashtable.[ch].
2828 * Changed the server's idlist routines to use the hash table
2829 routines to optimize the code.
2831 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Replaced the client entry's `channel' list and channel entry's
2834 `user_list' list to hash tables for optimized lookup. Changed
2835 the code to use the hash table interface around the code.
2836 Affected file lib/silcd/idlist.[ch].
2838 * Added `auto_rehash' boolean argument to the function
2839 silc_hash_table_alloc to indicate whether the hash table should
2840 auto-rehash when it thinks is appropriate time. It will
2841 increase the hash table size if the there is twice as much
2842 entries in the table than the size of the table, and will
2843 decrease the size if there are twice as less entries than
2844 the size of the table.
2846 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2850 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * silc_idcache_purge_by_context deletes the entry now by context
2853 as it is supposed to do. Affected file lib/silccore/idcache.c.
2855 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2856 client is not anymore valid (WHOWAS givens the info) and not
2857 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2859 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Removed the `data' and `data_len' arguments from the ID Cache
2862 interfaces and added `name' argument. ID Cache does not handle
2863 anymore the binary data only a names associated with given ID.
2865 * When hashing a Client ID with silc_hash_id the entire ID is
2866 not hashed anymore, instead only the hash of the Client ID is
2867 hashed. This way we can access the Client ID from the cache
2868 with Client ID but with the hash of the ID (which is a hash of
2869 the nickname) as well without any difference in performance.
2871 Added also silc_idcache_find_by_id_one_ext to do one on one
2872 searching when we have the actual ID. Added also function
2873 silc_hash_client_id_compare. The affected files are
2874 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2876 * When hashing the name associated with a ID it is always done
2877 in lowercase. This way we can access the cache without worrying
2878 about case-sensitivity, even though, for example nicknames are
2881 * Fixed a bug in server with channel message sending. It put
2882 wrong ID type as destination ID. The affected file
2883 silcd/packet_send.c.
2885 * silc_idcache_del_by_context now deletes from all hash tables
2886 by context. Affected file lib/silccore/idcache.c.
2888 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Changed the client library to use the new ID Cache interface.
2891 Changes around the source tree.
2893 * Added silc_hash_table_rehash_ext to rehash with specific
2894 hash function. Affected file lib/silcutil/silchashtable.[ch].
2896 * Added silc_hash_string_compare to compare two strings in the
2897 hash table. Affected file lib/silcutil/silcutil.[ch].
2899 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Added new function silc_idcache_del_by_context into the
2902 lib/silccore/idcache.[ch].
2904 * Changed the server's ID list routines to use the new ID Cache
2905 interface. Changes around the source tree.
2907 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2909 * Added silc_hash_table_del[_by_context]_ext functions in to the
2910 lib/silcutil/silchashtable.[ch].
2912 Removed silc_hash_table_find_all* routines and added new
2913 silc_hash_table_find_foreach to replace them.
2915 Added silc_hash_table_replace_ext function as extended
2916 replacing function. Separated the simple hash table interface
2917 from the extended hash table interface in the file
2918 lib/silcutil/silchashtable.h.
2920 * Fixed minor bugs and changed it to use some of the new
2921 hash table functions in lib/silccore/idcache.c
2923 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Added new function silc_hash_table_find_all to return all keys
2926 in the hash table by the specified key. As the hash table is
2927 collision resistant it also makes it possible to have several
2928 duplicate keys in the hash table. This function may be used to
2929 find all of the keys from the hash.
2931 Added user_context arguments to the SilcHashFunction,
2932 SilcHashCompare and SilcHashDestructor to deliver user specified
2935 Added new fuctions silc_hash_table_find[_all]_ext to do
2936 extended lookup with specified hash and compare functions and
2937 specified user contexts.
2939 Added new function silc_hash_table_add_ext to add the key
2940 with specified hash function and user context.
2942 Added new function silc_hash_table_foreach to traverse all
2943 entrys in the hash table. Added SilcHashForeach callback
2946 Added new function silc_hash_table_del_by_context to delete
2947 the entry only if the context associated with the key matches.
2949 Affected files are lib/silcutil/silchashtable.[ch].
2951 * Removed silc_hash_[server/client/channel]_id and added just
2952 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2953 silc_hash_id_compare to compare two ID's using as the hash table
2954 comparison function. Added also silc_hash_data to hash
2955 binary data and silc_hash_data_compare to compare it.
2957 * Removed silc_idlist_find_client_by_hash as it is not needed
2958 anymore. Affected file silcd/idlist.[ch].
2960 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2961 to use internally the SilcHashTable. The new ID Cache is a lot
2962 faster than the old one. Some of the ID Cache interface was also
2963 rewritten and obsolete and stupid functions were removed.
2965 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Added entry_count field to the SilcHashTable to keep the number
2968 of the entries in the table. Implemented the function
2969 silc_hash_table_rehash. Added new function
2970 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2972 Fixed a minor bug in silc_hash_table_free.
2974 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2975 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2976 into the lib/silcutil/silcutil.[ch].
2978 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2980 * Implemented a collision resistant hash table into the
2981 lib/silcutil/silchashtable[ch]. See the header and the source
2982 for the SilcHashTable API.
2984 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Merged dotconf version 1.0.2 into lib/dotconf.
2988 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2990 * Do not compile anything in lib/silcsim/* if the SIM support
2991 is not enabled. The tree should now compile without problems
2994 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Compiled the SILC under cygwin. Compiled and tested briefly
2997 without problems. More tests needed. The SIMs didn't compile
3000 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3002 * Fixed possible crash in silc_get_username in the
3003 lib/silcutil/silcutil.c.
3005 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed a va_arg in silc/client_ops.c.
3009 * Oops, RC5 routines were named AES and caused some problems
3010 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3012 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added new SilcIDIP structure into the lib/silccore/id.h and
3015 replaced the old `ip' fields from all SILC ID's to that type.
3016 This is a step towards IPv6 support.
3018 The silc_id_get_len takes now the ID as an extra argument.
3019 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3020 both IPv4 and IPv6 based ID's.
3022 The affected files are lib/silccore/id.[ch] and other files
3023 around the tree using these routines.
3025 * Removed the ID length arguments in server from various
3026 silc_server_send_notify_* routines -> they are not needed
3029 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Fixed memory leak in silc_encode_pem_file in the file
3032 lib/silcutil/silcutil.c.
3034 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Check minor version as well in the SKE. Affected files are
3037 silcd/protocol.c and lib/silcclient/protocol.c.
3039 * Added --identifier option to the server so that an identifier
3040 can be when creating the public key for the server. Affected
3041 file is silcd/silcd.c.
3043 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3044 lib/silccrypt/silcpkcs.c.
3046 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Register default ciphers and stuff when using -C option with
3049 the server. Affected file sildc/silcd.c.
3051 * Put back the servers public key filename format, it is better
3052 than the new one. For now, the client keys are saved with the
3053 new filename format. The affected file silc/client_ops.c.
3055 * Implemented the Cipher API for the rest of the ciphers that
3056 did not implement it or implemented it the wrong way.
3058 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Register default ciphers and stuff when using the -S option
3061 in the client. Affected file silc/silc.c. Same also when
3062 creating new key pair with -C option.
3064 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Fixed the silc_verify_public_key client operation function to
3067 save the public keys differently. The fingerprint is now
3068 used as filename and not the hostname. This way also the
3069 client keys are saved uniquely and not with hostnames. The
3070 affected file is silc/client_ops.c.
3072 * Trimmed the silc_hash_fingerprint function to remove extra
3073 whitespaces from the end of the fingerprint. The affected
3074 file is lib/silccrypt/silchash.c.
3078 * Added silc_cipher_register_default function to register all
3079 default ciphers. It can be used when configuration files
3080 does not exist and the application does not want any specific
3081 ciphers in any specific order.
3083 The SilcDList is now used as silc_cipher_list dynamically
3084 allocated cipher list. Removed the static list all together
3085 and now all ciphers must be allocated to the dynamic list.
3086 The silc_cipher_alloc routine was changed to check only the
3089 All silc_cipher_* routines that used to return int returns
3092 The affected files lib/silccrypt/silccrypt.[ch].
3094 * The same thing was done to silc_hash_* as for silc_cipher_*
3095 routines. Affected files lib/silccrypt/silchash.[ch].
3097 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3098 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3099 Added also silc_pkcs_[un]register[_default] functions.
3100 Removed the data_context from the PKCS API.
3102 * Added silc_hmac_register_default function to register default
3103 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3104 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3105 to unregister all hmacs at once.
3107 * Register the default ciphers, hash functions, PKCSs and HMACs
3108 if client's configuration file does not exist. The affected
3111 * The client did not load the hash functions from the SIM
3112 modules at all. Added support for this. Affected file is
3113 silc/clientconfig.c.
3115 * When decoding public key with silc_pkcs_public_key_decode, check
3116 the supported algorithm only if PKCS are registered. Affected
3117 file lib/silccrypt/silcpkcs.c. The same was done with the
3118 silc_pkcs_private_key_decode.
3120 * Fixed the SILC List routines to keep the list always in order.
3121 It used to change the list's order when traversing the list but
3122 not it preserves the order. Affected file lib/trq/silclist.h.
3124 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Added the client library to use the SilcSocketConnection's
3127 reference counter (by silc_socket_dup) to prevent the bug that
3128 the socket object may be freed underneath async operation.
3130 * The name resolv library checking fixes in the configure.in.pre.
3133 * Created new version of the protocol drafts for future
3134 development. The -03 drafts are the ones that will be changed
3135 in the trunk now and the -02 will remain as they are.
3137 * Send list of CUMODE notifys to the router when announcing
3138 the channel users to the router. Affected file silcd/server.c.
3139 If the router receiving channel founder CUMODE for a channel
3140 that already has channel founder it will send CUMODE notify
3141 to the sender to remove the channel founder rights from the
3142 announced client. Affected file silcd/packet_receive.c.
3144 * The CUMODE notify may now use Server ID as well as the entity
3145 who changes the mode. Updated protocool specs.
3147 * Updated INSTALL and README files.
3149 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * New web pages in the http://silc.pspt.fi. The pages was
3156 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Implemented the [DenyConnectin] config section in the server.
3159 Added silc_server_config_denied_conn to check whether incoming
3160 connection is denied. Affected file silcd/serverconfig.[ch].
3162 * Do not check the ports when checking the incoming configuration
3163 data if the port is 0, meaning any. Affected file is
3164 silcd/serverconfig.c.
3166 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Fixed buffer overflow in silc_string_compare in the file
3169 lib/silcutil/silcutil.c.
3171 * Fixed double free in silc_server_command_leave in the file
3174 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Fixed the version checking in the server. Affected file is
3179 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Fixed the configuration data fetching when accepting new
3182 connections in the server. Affected file silcd/server.c.
3184 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added `sender_entry' argument to the function
3187 silc_server_packet_relay_to_channel so that we can check
3188 whether some destination actually belongs to the same route
3189 the sender belongs (ie, we must not resend the packet to the
3190 sender). Affected file silcd/packet_send.[ch].
3192 * Added `servername' field to the SilcClientEntry in the server
3193 to hold the name of the server where client is from. Affected
3194 file is silcd/idlist.h.
3196 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Moved the channel message encrypting in the router betwen
3199 router connections from silc_server_channel_message to the
3200 silc_server_packet_relay_to_channel since we want to check
3201 whether we have anybody channel before encrypting anything.
3202 Affected files silcd/packet_[receive/send].c.
3204 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Fixed the [AdminConnection] server config section to support
3207 multiple entries. Affected file silcd/serverconfig.c.
3209 * Added support into the server to check the validity of the
3210 incoming connection before executing any KE or authentication
3213 * The connection configuration is now saved to the KE and
3214 connection auth protocol contexts and not fetched anymore in
3215 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3217 * The local hosts listenning address and port is also resolved
3218 now when starting the server. We want to have the socket object
3219 to include the real address and port for the listener. Added
3220 new function silc_net_check_local_by_sock into the files
3221 lib/silcutil/silcnet.[ch].
3223 * Fixed a broadcast bug in server -> do not broadcast if we
3226 * Fixed a routing bug. Do not route broadcast packets ever.
3227 Broadcast packets must be processed always and not routed since
3228 they may be destined to some other host than yourself and thus
3229 would get routed without no good reason. Affected file is
3232 * Added function silc_server_config_is_primary_route to check
3233 whether primary router connection has been configured (a router
3234 configuration that we are initiating). If there is not, we
3235 will assume that there is only two routers in the SILC network
3236 and we will use the incoming router connection as our primary
3237 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3239 * Changed the order of the broadcasting. Broadcast _after_ the
3240 packet has been processed not before. Affected file is
3243 * Fixed a [ClientConnection] parsing bug. The port was never
3244 parsed correctly thus resulting to port 0. Affected file
3245 silcd/serverconfig.c.
3247 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3248 argument and did not set the broadcast packet flag. Affected
3249 file silcd/packet_send.c. Fixed same bug in the function
3250 silc_server_send_notify as well.
3252 * If we receive NEW_ID packet for our own ID in the server, ignore
3255 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Removed the nickname from the Private Message Payload.
3260 Updated the code and the protocol specs.
3262 * Updated protocol specs for submitting to the IETF.
3264 * Tweaked the Random Number Generator a bit. Affected file
3265 lib/silccrypt/silcrng.c. Exported a new function
3266 silc_rng_[global]_add_noise which can be used to add more
3269 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Do not parse packets with different timeout when protocol
3272 is active -> may cause problem with rekey. Affected file
3275 * When server receives signoff notify it must not create
3276 new channel key if the client is on any channels since the
3277 sender of the signoff notify will create it.
3279 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Added printing of error messages during SKE protocol from the
3282 failure packet sent by server during SKE. Affected file
3285 * Removed the client's failure_callback handling with timeout
3286 and handle it immediately when received.
3288 * The SKE library returned wrong type in SUCCESS and FAILURE
3289 packets. They must be 32 bit MSB not 16 bit MSB.
3291 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3293 * Ok, rewrote the logic of the re-key and now it seems to work.
3294 I tested it on high traffic with frequent re-keys without
3295 problems. Added hmac_receive (and renamed hmac to hmac_send)
3296 in SilcClientConnection in lib/silcclient/client.h and
3297 in SilcIDListData in silcd/idlist.h. Also, removed the
3298 SilcPacketParserContext's cipher and hmac fields as they are
3299 not needed anymore and actually caused some problems when
3300 the ciphers and hmac's changed underneath the packet parser.
3302 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * If re-key protocol is active then process the incoming packets
3305 synchronously since we must assure that icoming packets encrypted
3306 with the old key is processed before the new keys is set to
3307 use. This is true other packets than for REKEY packets.
3308 Affected file silcd/server.c. The same was done to client library
3309 as well, affected file lib/silcclient/client.c.
3311 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Fixed bug in client and server to accept the force send if
3314 the packet is send from silc_[server/client]_packet_process
3315 function. Otherwise the packets are never delivered, oops.
3317 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Disable force sending of packets when REKEY protocol is active.
3320 We must assure that no packet is sent directly when rekey is
3321 performed. All packets must be sent through packet queue.
3322 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3323 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3324 function is silc_[server/client]_packet_send_real to check
3327 * Replaced the SIM paths from example config files to
3328 /usr/local/modules. Also, make install creates now
3329 /usr/local/silc/logs directory to hold all the SILC server
3332 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Made the configure.in.pre work on Solaris. Patch by salo.
3336 * Made all ciphers compatible with non-x86 machines. Defined
3337 CBC mode macros into lib/silccrypt/ciphers_def.h.
3339 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Fixed the make install.
3343 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * When MAC computation fails the silc_packet_decrypt returned 0
3346 even though it was supposed to return -1. Fixed this. The
3347 affected file is lib/silccore/silcpacket.c.
3349 * Do not replace the config files in /etc/silc (in make install)
3350 if they already exist. Affected file ./Makefile.am.
3352 * Do not send re-key packets immediately but through packet queue.
3353 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3355 * Changed silc_net_check_host_by_sock to return FALSE if the
3356 IP/DNS could not be resolved. Though, it returns the IP address
3357 now even if it could not resolve it (but returns also FALSE).
3358 Affected file lib/silcutil/silcnet.[ch].
3360 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added silc_pkcs_decode_identifier to decode the public key's
3363 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3364 Added also silc_pkcs_free_identifier. Added also new context
3365 SilcPublicKeyIdentifier.
3367 * Added -S option to the silc client. It is used to dump the
3368 contents of the specified public key file.
3370 * Changed the PKCS api to return the public key length when
3371 setting the public key.
3373 * Fixed a fatal bug in the public and private key file loading.
3374 Affected file lib/silccrypt/silcpkcs.c.
3376 * Execute the packet parsing for client with zero (0) timeout
3377 if the protocol is active. Affected file silcd/server.c.
3379 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Made the key generation options to the silcd program. Added
3382 -C option, equivalent to client's option.
3384 * Added new [ServerKeys] config section to the server. It
3385 configures the server's public and private key.
3387 * Defined generic Public Key Payload into the protocol
3388 specification to send specific type of public keys and
3391 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3392 public key or certificate.
3394 * Implemented the GETKEY command to the server and to the
3395 client library and on user interface.
3397 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Made preliminary `make install' work.
3401 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Added SilcServerRekey context into silcd/idlist.h.
3405 * Added the PFS support as defined in the specification to the
3406 SKE protocol. Affected files lib/silcske/*.c.
3408 * Added `ske_group' field to the SilcServerRekey context to hold
3409 the number of the SKE group that is used with PFS in re-key.
3410 Affected file silcd/idlist.h.
3412 * Added PFS re-key support to the server. Affected file is
3415 * Added silc_protocol_cancel to cancel execution of the next
3416 state of the protocol. Affected file is
3417 lib/silccore/silcprotocol.[ch].
3419 * Added the re-key support with and without PFS to the client
3420 library. Re-key is performed once in an hour, by default.
3422 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3423 Added silc_client_rekey_callback and silc_client_rekey_final.
3424 Affected files are lib/silcclient/protocol.[ch] and
3425 lib/silcclient/client.[ch].
3427 * Removed the `hmac_key' and `hmac_key_len' fields from the
3428 SilcClientConnection structure; not needed. Affected file is
3429 lib/silcclient/client.h.
3433 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Do not ask whether user wants to use the negotiated private key
3436 for private messages, just use it. Affected file is
3437 silc/local_command.c.
3439 * Added `send_enc_key' and `enc_key_len' fields to the
3440 SilcIDListData structure since they are needed in the re-key
3441 phase. Affected file is silcd/idlist.[ch].
3443 * Implemented the simple re-key protocol into the server.
3444 Affected files silcd/server.c and silcd/protocol.[ch]. The
3445 re-key will be performed once in an hour, by default.
3447 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3448 Added silc_server_rekey, silc_server_rekey_callback and
3449 silc_server_rekey_final.
3451 * Removed Tunneled flag from the protocol. Updated the code
3452 and the specifications.
3454 * Adde `pfs' field to the SilcIDListData to indicate whether
3455 the PFS is to be performed in the re-key. Affected file is
3458 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3461 int64 of at least the xintXX size. If void * is less that 4
3462 bytes uint32 * will be used. Defined bool as boolean.
3464 * Changed _ALL_ unsigned long and unsigned int to uint32,
3465 unsgined short to uint16 in the source tree.
3467 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3468 not handle clients that has entry->data.registered == FALSE.
3469 They are not in the network anymore. Affected file is
3472 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Implemented the sending of the SERVER_SIGNOFF notify in the
3475 server. Affected file is silcd/server.c.
3477 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3478 Added also silc_notify_payload_encode_args into the
3479 lib/silccore/silcnotify.[ch].
3481 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3482 Affected file silcd/packet_receive.c.
3484 * Implemented the SERVER_SIGNOFF notify handling in the client
3485 library. Affected file lib/silcclient/client_notify.c. Also,
3486 implemnted the printing of the SERVER_SIGNOFF info to the
3487 application. Affected file silc/client_ops.c.
3489 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3490 if the deleting was successful. Affected file silcd/idlist.[ch].
3492 * Added support for public key authentication in the connection
3493 authentication protocol in the client library. Affected file
3494 lib/silcclient/protocol.c.
3496 * Changed the server's silc_idlist_get_clients_by_* interface
3497 to support already allocated array so that new entries may be
3498 added to pre-allocated array. Affected file silcd/idlist.[ch].
3499 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3500 and command replies.
3502 * All command reply functions in the server now calls the
3503 pending command callback even if error occured. This way the
3504 error will be delivered to the client as well. Affected files
3505 silcd/command.c and silcd/command_reply.c.
3507 * Fixed INFO command to return local server's info if no server
3508 was provided. Affected file lib/silcclient/command.c.
3510 * Removed RESTART command for good. Updated the code and the
3513 * Rewrote parts of the task system. It is a bit simpler now.
3514 Removed unsued task priorities. The affected files are
3515 lib/silcutil/silctask.[ch].
3517 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Moved the USERS printing from the library to the application.
3520 Affected files lib/silcclient/command.c and silc/client_ops.c.
3522 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Added channel key re-key support. The re-key is perfomed
3527 only by the router and is done once in an hour. Added `rekey'
3528 field to the SilcChannelEntry in the server. Affected files
3529 silcd/server.c and silcd/idlist.h.
3531 * Added silc_task_unregister_by_context into the file
3532 lib/silcutil/silctask.[ch].
3534 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Added SILC_UMODE_GONE mode to indicate when the client is not
3537 present in the SILC network. Added also support to the local
3538 command AWAY that will set this mode. Added support of showing
3539 "xxx is gone" in WHOIS command. The USERS command shows the
3540 gone status as well.
3542 * Fixed setting server and router operator privileges in the
3543 server's UMODE command. Affected file silcd/command.c.
3545 * Merged the SKE KE1 and KE2 payloads into one payload. The
3546 new KE payload is equivalent to the old KE2 payload.
3548 Cleaned up the SKE Start Payload parsing. It now uses the
3549 simple buffer unformatting to do the parsing. A lot faster
3552 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3553 to the SKE that is used to indicate whether both of the SKE
3554 parties should perform authentication. By default only the
3555 responder performs authentication. By setting this flag also
3556 the initiator must do authentication. By default it is unset
3557 since in normal SKE case, client to server connection, only
3558 the responder should do authentication. When doing SKE between
3559 two clients both should perform authentication. Updated the
3560 code and the protocol specs.
3562 * A little fix to IDENTIFY command in the server. Search the
3563 client first by hash not nickname. Affected file is
3566 * Fixed the silc_client_close_connection to support closing
3567 the client to client connections wihtout deleting too much
3568 data. Affected file lib/silcclient/client.c.
3570 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3571 are received if protocol used to be active but is not anymore
3572 the application would crash due to NULL pointer dereference.
3573 Affected files silcd/server.c and lib/silcclient/client.c.
3575 * Added `hash' field to the SilcClientConnection to include
3576 the hash function negotiated in the SKE protocol.
3578 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3579 to set the channel founder authentication data. A client can
3580 claim the founder rights later by providing the authentication
3581 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3582 This way the channel founder can regain the channel founder
3583 privileges even it is left the channel. This works only on
3584 local server and the client must be connected to the same
3585 server to be able to regain the founder rights. Updated the
3586 protocol specs accordingly.
3588 Added support to the CMODE command in the client to set the
3589 founder auth data. Read the README to see how to set it.
3591 Added support to the CUMODE command to claim the founder
3592 rights. Read the README to see how to do it.
3594 Added support for the founder authentication to the Channel
3595 Entry in the server. Affected file silcd/idlist.h.
3597 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3598 server's CMODE command. Affected file silcd/command.c.
3600 * Added the following new functions into lib/silccore/silcauth.[ch]:
3601 silc_auth_get_method and silc_auth_get_data.
3603 * The server now saves the remote hosts public key to the
3604 SilcIDListData pointer. Affected file silcd/protocol.c.
3606 * The normal server now does not remove the channel entry from
3607 the cache if the founder authentication data is set. It used
3608 to remove it if the founder was the last one on the channel on
3609 the server and left the channel. The auth data is saved and
3610 if the channel is re-joined later the old entry is used with
3611 the old auth data. Affected files silcd/command_reply.c and
3614 * Removed the `pkcs' field from the SilcIDListData structure
3615 in the server; it is not used. Affected file silcd/idlist.h.
3617 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3619 * Fixed packet processing on slow links. Partial packets were
3620 never re-processed because the incoming data buffer was cleared
3621 by the application. Application must not directly clear the
3622 sock->inbuf, the packet processing routines handle it. Fixed
3623 this in client library and in server.
3625 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3627 * Fixed the WHOIS and IDENTIFY send reply function to really
3628 check whether to send list or just one entry. Affected file
3631 * Cleaned up the LEAVE command's channel key distribution. The
3632 affected file silcd/command.c.
3634 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3635 can enforce the channel mode as well. In that case the ID
3636 includes the ID of the server. The code now enforces the
3637 mode change if the router have different mode than the server.
3639 * The notify client operation with CMODE_CHANGE notify can now
3640 return NULL client_entry pointer if the CMODE was not changed
3641 by client. Application must check for this.
3643 * Added <Server ID> argument to INFO command to support server
3644 info fetching by Server ID.
3646 * Added silc_server_announce_get_channel_users to get assembled
3647 packets of channel users of the specified channel. Affected
3648 file silcd/server.[ch].
3650 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3651 was freed underneath the ID Cache.
3653 * Re-announce clients when the server received CHANNEL_CHANGE
3654 notify from the router. Affected file silcd/packet_send.c.
3656 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3659 crashed since it did not handle the fact that there is no cipher
3660 called "3" and didn't check the error condition. Now fixed.
3662 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3663 flag. It can be used to send message requests.
3665 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Implemented the RESTART command in the client.
3669 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3670 notice type messages. Added notice printing to the user
3673 * The channel keys are not re-generated if the channel's mode
3674 is PRIVKEY, ie private key on the channel exists. Affected
3675 files silcd/server.c and silcd/command.c.
3677 * Fixed a little bug in channel message delivery when channel
3678 private keys are set in the server. Affected file is
3679 silcd/packet_send.c.
3681 * Changed the setting on channel->on_channel = TRUE from the
3682 silc_client_save_channel_key to the JOIN command reply. The
3683 key payload is not received if the private channel key is set.
3684 Affected file lib/silcclient/command_reply.c and the
3685 lib/silcclient/client_channel.c.
3687 * When the CMODE_CHANGE notify is sent and the channel private
3688 key mode is removed the channel key must be re-generated in
3689 other cells as well. Added this support for the router in the
3690 silcd/packet_receive.c.
3692 * Added new local command NOTICE to send notice message on
3693 channel. Affected file silc/local_command.[ch].
3695 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Added new local command ME to the client. It is used to send
3698 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3699 some action. Affected file silc/local_command.[ch].
3701 * Changed channel_message and private_message client operations
3702 to deliver the message flags to the application. Added also
3703 the `flags' arguments to the silc_client_send_channel_message
3704 and silc_client_send_private_message functions. Affected file
3707 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Redefined the Private Message Payload to support private message
3710 keys and to support the new private message flags. Updated
3711 the protocol specs. Flags makes it possible to have for example
3712 CTCP style messages.
3714 * Added new type SilcPrivateMessagePayload and defined an API
3715 for it in the lib/silcclient/silcprivate.[ch].
3717 * Tested private message private keys successfully. Tested the
3718 private message key set, unset and list commands with the new
3721 * Redefined the Channel Message Payload to include the channel
3722 message flags (equal with private message flags) to support
3723 for example CTCP style messages.
3725 * Defined some of the message (for channel and private message)
3726 flags. Updated the protocol specs and added the flags to the
3727 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3729 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Added SilcKeyAgreementStatus type to the key agreement routines
3732 to indicate the current status and error if one occured.
3733 The status types are defined in the lib/silcclient/silcapi.h.
3735 * Added new local command KEY that is used to set and unset private
3736 keys for channels, set and unset private keys for private messages
3737 with remote clients and to send key agreement requests and
3738 negotiate the key agreement protocol with remote client. The
3739 key agreement is supported only to negotiate private message keys,
3740 it currently cannot be used to negotiate private keys for channels,
3741 as it is not convenient for that purpose.
3743 * Fixed a minor pending callback setting bug in the function
3744 silc_client_get_client_by_id_resolve, now the function works.
3745 Affected file lib/silcclient/idlist.c.
3747 * Added function silc_net_get_local_port to get local bound
3748 port by socket. Added to lib/silcutil/silcnet.[ch].
3750 * Added `sockets' and `sockets_count' fields to the SilcClient
3751 object. They hold the sockets of the listenning sockets in
3752 the client. Listenning sockets may be for example the key
3753 agreement server. Affected file lib/silcclient/client.[ch].
3754 Added functions the silc_client_add_socket and the
3755 silc_client_del_socket. They are exported to the application
3758 * Added ~./silc/clientkeys to support other client's public keys.
3760 * Renamed verify_server_key client operation to verify_public_key
3761 and added one argument to indicate the type of the connection
3762 (server, client etc.).
3764 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added silc_server_connection_auth_request to handle the
3767 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3768 silcd/packet_receive.[ch].
3770 * Added silc_server_send_connection_auth_request into the
3771 silcd/packet_send.c to send the connection auth request packet.
3773 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3776 * Fixed the public key authentication in responder side in the
3777 server. The `auth_data' pointer includes the SilcPublicKey
3778 not the path to the public key. Affected file silcd/protocol.c.
3780 * Implemented the public key authentication in the initiator side
3781 in the server. Affected file silcd/protocol.c.
3783 * Removed the [RedirectClient] config section from the server
3784 configuration. Is not needed and I don't want to implement it.
3786 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Cleaned up the CMODE command in the server. It now works
3789 correctly and supports all the modes defined in the protocol.
3790 Affected file is silcd/command.c.
3792 * Added `hmac_name' field to the SilcChannelEntry in the server
3793 to hold the default HMAC of the channel. It can be set when
3794 creating the channel (with JOIN command). Affected files
3797 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3798 type to indicate the change of the current cipher and hmac
3799 on the channel. Client can safely ignore the <cipher> argument
3800 (if it chooses to do so) since the CHANNEL_KEY packet will
3801 force the channel key change anyway. The <hmac> argument is
3802 important since the client is responsible of setting the new
3803 HMAC and the hmac key into use.
3805 * Fixed the CMODE command in the client library as well.
3807 * Tested CMODE command in router environment successfully.
3809 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Show the version of the remote client (or server) when connecting
3812 to the server. It is logged to the log file. Affected file
3813 is silcd/protocol.c.
3815 * Fixed the KILLED notify handling in the client library. The
3816 client must be removed from all channels when receiving the
3819 Also, do not remove the client entry when giving the KILL
3820 command but when the KILLED notify is received.
3822 * Removed silc_idlist_find_client_by_nickname from the server.
3823 Not needed anymore. Affected files silcd/idlist.[ch].
3825 * Implemented the CHANNEL_CHANGE notify type handling to the
3826 server. Affected file silcd/server.c.
3830 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Added silc_server_send_notify_invite to send the INVITE
3833 notify between routers.
3835 * Implemented the INVITE command correctly to the server.
3837 * Implemented the INVITE notify type handling in the server.
3839 * Implemented the INVITE command to the client library and on the
3842 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Added function silc_server_get_client_resolve to find the
3845 client entry by ID from all ID lists and then resolve it
3846 (using WHOIS) if it cannot be found. Affected file is
3849 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Implemented the BAN command to the client library.
3853 * The JOIN command in the server now checks the invite list
3856 * Changed the silc_command_reply_payload_encode_va and the
3857 silc_command_payload_encode_va to support that if argument is
3858 NULL it ignores and checks the next argument. Affected file
3859 lib/silccore/silccommand.c.
3861 * Added silc_server_send_notify_ban to send the BAN notify
3862 type between routers.
3864 * Chaned the silc_notify_payload_encode to support that if
3865 argument is NULL it ignores and checks the next argument.
3866 Affected file lib/silccore/silcnotify.c.
3868 * Tested ban lists in router environment successfully.
3870 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Implemented BAN command to the server, in silcd/command.[ch].
3874 * Removed the BAN and INVITE_LIST modes from the CMODE command
3877 * Added function silc_string_match to regex match two strings.
3878 Affected files lib/silcutil/silcutil.[ch].
3880 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Redefined parts of the SilcChannelEntry in the server to support
3883 the new ban and invite lists.
3885 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Redefined the INVITE command. The same command can be used to
3888 invite individuals to the channel but also to manage the invite
3889 list of the channel (to add to and remove from the invite list).
3890 Updated the protocol specs.
3892 * Added new command SILC_COMMAND_BAN that can be used to manage
3893 the ban list of the channel. Updated the protocol specs.
3895 * Removed the channel modes: the SILC_CMODE_BAN and the
3896 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3897 in the CMODE command. The equivalent features are now available
3898 using INVITE and BAN commands. Updated the protocol specs.
3900 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3901 in the network about change in the current ban list. The notify
3902 type is not used by the client.
3904 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3905 support the invite lists.
3907 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Added new function silc_string_regexify that converts string
3910 including wildcard characters into regex string that can
3911 be used by the GNU regex library. Added into the file
3912 lib/silcutil/silcutil.[ch].
3914 Added silc_string_regex_combine to combine to regex strings
3915 into one so that they can be used as one regex string by
3916 the GNU regex library. Added into the file
3917 lib/silcutil/silcutil.[ch].
3919 Added silc_string_regex_match to match two strings. It returns
3920 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3922 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Imported GNU regex to the soruce tree into lib/contrib.
3925 Fixed some compiler warning from the regex.c.
3927 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Fixed MOTD command in the server to work in router environment.
3931 * Fixed the MOTD command in the client library to support
3932 the server argument in the command.
3934 * Added `nickname_len' argument to the silc_idlist_add_client
3935 in the server, as the `nickname' argument may be binary data
3938 * Added silc_idlist_get_channels to return all channels from
3941 * Implemented LIST command to the server. Affected file is
3944 * Implemented the LIST command to the client library and on the
3947 * Added [<user count>] argument to the LIST command reply.
3948 With private channels the user count is not shown.
3950 * Updated TODO and README.
3952 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * The client entry's data.registered must be TRUE even with
3955 global client entry on global client list. The data.registered
3956 is used to check whether the client is anymore in the network,
3957 for example with WHOWAS command so it must be valid.
3959 * Fixed the WHOWAS command in the server. It now actually works
3960 in router environment. Added function into silcd/command_reply.c
3961 silc_server_command_reply_whowas_save.
3963 * Added silc_idlist_purge function to the silcd/idlist.c
3964 to periodically purge the ID Cache.
3966 * Fixed INFO command in the server. It works now in router
3967 environment. Added <server name> argument to the INFO command
3968 reply. Updated the protocol specs.
3970 * Fixed minor bug in silc_idcache_purge to not purge if the
3971 expire value is zero.
3973 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3974 they were buggy because of the WHOWAS information.
3976 * Fixed local command MSG to handle the async resolving of
3977 the remote client properly. It used to fail the first MSG.
3978 Affected file silc/local_command.c.
3980 * Added `data_len' field to SilcIDCache context.
3982 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Update TODO. Todo in commands in the server.
3986 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3989 used by routers as broadcast packet to inform other routers
3990 about the changed user mode.
3992 Implemented the notify handling in the server. Affected file is
3993 silcd/packet_receive.c. Added the function
3994 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3996 * Added new generic Channel Payload and deprecated the New Channel
3997 Payload. The New Channel Payload is now the generic Channel
4000 * Added new argument `mode' to the silc_server_send_new_channel
4001 as it is required in the Channel Payload now.
4003 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4004 and created a new and real SilChannelPayload to represent the
4005 new generic Channel Payload. Implemented the encode/decode
4006 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4008 * Added silc_server_get_client_channel_list to return the list
4009 of channels the client has joined for WHOIS command reply.
4010 Affected file silcd/server.[ch].
4012 * Implemented the channel list sending in the WHOIS command reply
4013 in server and in the client.
4015 Implemented the channel list displaying on the user interface
4016 as well. Affected file silc/client_ops.c.
4018 * Added silc_channel_payload_parse_list to parse list of Channel
4019 Payloads. It returns SilcDList list of SilcChannelPayloads.
4020 Client for example can use this function to parse the list of
4021 channels it receives in the WHOIS command reply. The caller
4022 must free the list by calling silc_channel_payload_list_free.
4023 Affected files lib/silccore/silcchannel.[ch].
4025 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Added one new argument <user mode> to the WHOIS command reply
4028 to return the mode of the user in SILC. Updated the protocol
4031 Implemented it to the server and client.
4033 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Fixed the mode printing on the user interface on joining.
4036 Affected file silc/client_ops.c.
4038 * Implemented the UMODE command and user modes in general to the
4039 client library and to the user interface.
4041 * Implemented the UMODE command to the server.
4043 * The server now sends UNKNOWN_COMMAND error status if client sends
4044 unknown command. Affected file silcd/command.c.
4046 * All server commands now handle the command identifier the right
4047 way when sending the command reply to the client. The client can
4048 use to identify the command replies with the identifier.
4050 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Added silc_server_get_client_route to resolve the route to
4053 the client indicated by the client ID. Affected file is
4056 * Added silc_server_relay_packet as general function to relay
4057 packet to arbitrary destination. This deprecates functions
4058 like _send_private_message_key, _relay_notify etc. Affected
4059 file is silcd/packet_send.[ch].
4061 Removed silc_server_send_key_agreement,
4062 silc_server_send_private_message_key and
4063 silc_server_packet_relay_notify functions from the file
4064 silcd/packet_send.[ch].
4068 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4069 server. Affected file silcd/packet_receive.[ch].
4071 * Implemented the KILL command to the client. Implemented the
4072 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4073 Affected files lib/silcclient/command[_reply].c and
4074 lib/silcclient/client_notify.c. Implemented the KILL notify
4075 printing in the user inteface.
4077 * Fixed a lot silc_parse_nick memory leaks from the client
4078 library in the file lib/silcclient/command.c.
4080 * Changed the silc_server_send_notify_on_channels's `sender'
4081 argument from SilcSocketConnection to SilcClientEntry to
4082 check the sender as entry and not as connection object and not
4083 to send to the client provided as argument. The affected file
4084 is silcd/packet_send.[ch].
4086 * The notify packets that are destined directly to the client used
4087 to not to be processed by the server. Now changed that and the
4088 server processes all notify packets. After relaying the packet
4089 to the client the notify packet is processed in the server.
4091 * The silc_server_free_client_data now checks whether there is
4092 pending outgoing traffic for the client and purges the data to
4093 the network before removing the client entry.
4095 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4098 an client is killed from the SILC Network. Updated the protocol
4101 Added new function silc_server_send_notify_killed to the
4102 silcd/packet_send.[ch].
4104 * Added function silc_server_packet_relay_notify to relay notify
4105 packets that are destined directly to a client. In this case
4106 the server does not process the notify packets but merely relays
4107 it to the client. Affected file silcd/packet_send.[ch].
4109 Added also silc_server_packet_process_relay_notify to check
4110 whereto relay the notify. Affected file is
4111 silcd/packet_receive.[ch].
4113 * Implemented the KILL command to the server.
4117 * Added the backup schema desgined last fall to the protocol
4118 specs for everyone to see. The specification is in the
4119 *-spec-xx.txt draft and the packet type definitions for the
4120 backup routers is in *-pp-xx.txt draft. Thusly, added also
4121 new packet type SILC_PACKET_CELL_ROUTERS.
4123 * A big security problem in the implementation discovered. The
4124 signoff of an client did not cause new channel key generation
4125 which it of course should've done. The channel keys must be
4126 always re-generated when client leaves (or signoffs) the channel.
4127 The silc_server_remove_from_channels funtion now handles
4128 the channel key re-generation.
4130 * Added `sender' argument to the silc_server_send_notify_on_channels
4131 to not to send the client provided as argument. Affected file
4132 silcd/packet_send.[ch].
4134 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Implemented OPER and SILCOPER commands into the server and
4139 * Added silc_auth_verify and silc_auth_verify_data to verify
4140 the authentication directly from the authentication payload.
4141 It supports verifying both passphrase and public key based
4142 authentication. Affected file lib/silccore/silcauth.[ch].
4144 * Added `hash' field to the SilcIDListData structure. It is the
4145 hash negotiated in the SKE protocol. Affected file is
4148 * Slight redesigning of the SilcAuthPayload handling routines.
4149 Do not send SilcPKCS but SilcPublicKey as argument.
4151 * Implemented the public key authentication support to the
4152 serverconfig. The public key is loaded from the provided path
4153 and saved as authentication data to void * pointer. Thus,
4154 changed the unsigned char *auth_data to void *auth_data;
4156 * Fixed SHUTDOWN command to send the reply before the server
4157 is shutdown. :) Affected file silcd/command.c.
4159 * Fixed fatal bug in CONNECT command. The hostname was invalid
4160 memory and server crashed. Affected file silcd/command.c.
4162 * Fixed fatal bug in CLOSE command. The server_entry became
4163 invalid but was referenced later in the command. Affected file
4166 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed fatal bug in failure packet handling. Server ignored
4169 the failure and thus crashed when it came.
4173 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4176 that the command may be executed only once in (about) 2 seconds.
4177 The old SILC_CF_LAG flag is same but allows command bursts up
4178 to five before limiting.
4180 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4181 server code. Various commands now includes the CF_LAG_STRICT
4182 flag to disallow any kind of miss-use of the command.
4184 * Fixed the silc_buffer_unformat to not to allocate any data
4185 if the length of the data is zero. It used to allocate the
4186 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4188 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Changed the format of AdminConnection configuration section
4191 in the server. Added username of the admin to the format.
4192 Affected files silcd/serverconfig.[ch].
4194 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4195 to return admin configuration data by host, username and/or
4198 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Implemented WHOWAS command to the server. Added the functions:
4202 silc_server_command_whowas_parse,
4203 silc_server_command_whowas_send_reply,
4204 silc_server_command_whowas_from_client and
4205 silc_server_command_whowas_from_server
4207 * Added <Client ID> argument to the WHOWAS command reply. Updated
4208 the protocol specs accordingly.
4210 * Implemented WHOWAS command and command_reply to the client
4213 Implemented the WHOWAS printing on the user interface.
4215 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Added new argument to the WHOWAS command reply, the real name.
4218 It is an optional argument. Updated the protocol specs.
4220 * Added SilcIDCacheDestructor callback that is registered when
4221 the SilcIDCache is allocated. The callback is called when
4222 an cache entry in the ID Cache expires, or is purged from the
4223 cache. Added into lib/silccore/idcache.[ch].
4225 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4226 to destruct the client entries when the cache entry expires.
4227 Other ID Cache's in server and in the client library ignores
4230 * If the ID Cache entry's `expire' field is zero then the entry
4231 never expires. Added boolean `expire' argument to the
4232 silc_idcache_add function in the lib/silccore/idcache.[ch].
4233 If it is TRUE the default expiry value is used.
4235 * Added silc_server_free_client_data_timeout that is registered
4236 when client disconnects. By default for 5 minutes we preserve
4237 the client entry for history - for WHOWAS command.
4239 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Added support to the server to enforce that commands are not
4242 executed more than once in 2 seconds. If server receives
4243 commands from client more frequently, timeout is registered
4244 to process the commands. Affected file silcd/command.c.
4245 Added new function silc_server_command_process_timeout.
4247 * Changed NICK_NOTIFY handling in client library to check that
4248 if the client's nickname was changed, so there is no need to
4249 resolve anything from the server.
4251 * Removed error printing from the WHOIS and IDENTIFY commands.
4252 If error occurs then it is ignored silently in the client library.
4253 The application, however, may map the received error to
4254 human readable error string. The application currently maps
4255 the NO_SUCH_NICKNAME error to string.
4257 * Made the command status message public to the application. Moved
4258 them from lib/silcclient/command_reply.c to
4259 lib/silcclient/command_reply.h. The application can map the
4260 received command status to the string with the
4261 silc_client_command_status_message function.
4263 * Added check to the server to check that client's ID is same
4264 as the Source ID in the packet the client sent. They must
4267 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Added dist-bzip hook to the Makefile.am to make bzip2
4270 compressed distributions.
4272 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Server now enforces the maximum length for the nickname and
4275 the channel as protocol specification dictates. 128 bytes for
4276 nickname and 256 bytes for channel name.
4278 * Moved the WHOIS printing to the application. The client libary
4279 does not print out the WHOIS information anymore, the application
4280 must do it. Renamed silc_client_command_reply_whois_print to
4281 the silc_client_command_reply_whois_save.
4283 The client's idle time is also sent to the application now, and
4284 the idle is shown on screen.
4286 * Added silc_client_command_reply_identify_save to save the
4287 received IDENTIFY entries.
4289 * Do not check for channel private keys in message sending and
4290 reception if the channel does not have the PRIVKEY mode set.
4291 Affected file lib/silclient/client_channel.c.
4293 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4296 just surfaced after chaning the JOIN procedure.
4298 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Added silc_client_get_clients_by_list to get client entries
4301 from Client ID list, that is returned for example by JOIN
4302 and USERS command replies. The application should use this
4303 function for example when JOIN command reply is received to
4304 resolve the clients already on the channel (library does not
4305 do that anymore as USERS command reply is not used in the JOIN
4306 procedure anymore). Affected files lib/silcclient/silcapi.h and
4307 lib/silcclient/idlist.c.
4309 * JOIN command reply and USERS command reply returns now SilcBuffer
4310 pointers instead of unsigned char pointers when returning
4311 the client list and mode list.
4313 * Added <Client ID> argument to the JOIN command reply, mainly
4314 for the server to identify for which client the command was
4315 originally sent. Updated protocol specs accordingly.
4317 * Added SilcDlist private_key pointer to the SilcChannelEntry
4318 in the client to support the channel private keys. Affected
4319 file is lib/silcclient/idlist.h.
4321 * Added SilcChannelPrivateKey argument to the function
4322 silc_client_send_channel_message so that application can choose
4323 to use specific private ke if it wants to. If it is not provided,
4324 the normal channel key is used, unless private keys are set.
4325 In this case the first (key that was added first) is used
4326 as the encryption key.
4328 * Implemented the support for channel private key handling.
4329 Implemented the following functions:
4331 silc_client_add_channel_private_key,
4332 silc_client_del_channel_private_keys,
4333 silc_client_del_channel_private_key,
4334 silc_client_list_channel_private_keys and
4335 silc_client_free_channel_private_keys
4337 Affected file lib/silcclient/client_channel.c.
4339 * Added the support for the private keys in the channel message
4340 sending and encryption and in the message reception and
4341 decryption. Affected funtions are
4342 silc_client_send_channel_message and silc_client_channel_message.
4344 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Added SKE's key verify callback to the client library's
4347 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4349 * Removed the statement that server (or router) must send USERS
4350 command reply when joining to the channel so that the client
4351 knows who are on the channel. Instead, the client list and
4352 client's mode list is now sent in the JOIN command reply to the
4353 client who joined channel. This is better solution.
4355 * Added function silc_server_get_users_on_channel and function
4356 silc_server_save_users_on_channel to the silcd/server.[ch].
4358 * Removed function silc_server_command_send_users from the
4361 * Do not show topic on the client library anymore. The topic is
4362 sent in the command reply notify to the application and the
4363 application must show the topic now.
4365 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added client searching by nickname hash into the IDENTIFY and
4368 WHOIS commands in the server as they were clearly missing from
4369 them. Affected file is silcd/command.c.
4371 * Fixed a bug in private message receiving in the client library.
4372 The remote ID was freed and it wasn't supposed, now it is
4375 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Minor fix to the channel payload; allocate the data area, as it
4378 needs to be of specific length.
4380 * If the key agreement port is zero then the operating
4381 system will define the bound port. Affected files are
4382 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4384 * Added new function silc_channel_payload_decrypt into the file
4385 lib/silccore/silcchannel.[ch].
4387 * Moved the channel message etc, check from silc_packet_decrypt
4388 to applications. The library calls now a generic
4389 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4390 when the packet is either normal or special. This was done to
4391 allow more wide range of checking that was not allowed when
4392 the code was in library. Now applications can do virtually any
4393 checks to the packet and return to the library the decision how
4394 the packet should be processed. Affected files are
4395 lib/silccore/silcpacket.[ch].
4397 Added silc_server_packet_decrypt_check to the server and
4398 silc_client_packet_decrypt_check to the client library.
4400 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4401 to send with specified source and destination information.
4403 * Channel message delivery between routers was broken after the
4404 channel key distribution was fixed earlier. The channel key
4405 was used be to distributed to other routers as well which is not
4406 allowed by the protocol. Now this is fixed and channel keys
4407 really are cell specific and the channel message delivery between
4408 routers comply with the protocol specification.
4410 * Fixed various commands in server to check also the global list
4411 for the channel entry and not just the local list. The affected
4412 file silcd/command.c.
4414 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added assert()s to buffer formatting and unformatting routines
4417 to assert (if --enable-debug) when error occurs. Affected
4418 file: lib/silcutil/silcbuffmt.c.
4420 * Changed to auto-reconnect to check whether the remote host is
4421 router and register the re-connect timeout if it is. It used
4422 to check that whether we are normal server, but router must do
4423 auto-reconnect with another router as well. Affected file
4426 * Removed the [<key len>] option from CMODE command as the cipher
4427 name decides the key length, nowadays. See the defined ciphers
4428 from the protocol specification.
4430 * Added [<hmac>] option to the CMODE command to define the HMAC
4431 for the channel. Added SILC_CMODE_HMAC channel mode.
4433 * Added [<hmac>] option for the JOIN command so that user can
4434 select which HMAC is used to compute the MACs of the channel
4437 * Added Hmac field to the Channel Message Payload. The integrity
4438 of plaintext channel messages are now protected by computing
4439 MAC of the message and attaching the MAC to the payload. The
4440 MAC is encrypted. Now, it is clear that this causes some
4441 overhead to the size of the packet but rationale for this is that
4442 now the receiver can verify whether the channel message decrypted
4443 correctly and also when private keys are set for the channel the
4444 receiver can decrypt the packet with several keys and check from
4445 the MAC which key decrypted the message correctly.
4447 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4448 lib/silccrypt/silccipher.[ch].
4450 * Added silc_hash_len to return the digest length into the
4451 lib/silcrypt/silchash.[ch].
4453 * Rewrote parts of Silc Channel Payload interface in the
4454 lib/silccore/silcchannel.[ch]. The encode function now also
4455 encrypts the packet and parse function decrypts it.
4457 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Fixed a minor formatting bug in the SKE's key material processing.
4460 It actually might have processed the keys wrong way resulting
4463 * Redefined the mandatory HMAC algorithms and added new algorithms.
4464 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4465 and hmac-md5 truncated to 96 bits. The mandatory is now
4466 hmac-sha1-96. Rest are optional (including the one that used
4467 to be mandatory). Rationale for this is that the truncated HMAC
4468 length is sufficient from security point of view and can actually
4469 make the attack against the HMAC harder. Also, the truncated
4470 HMAC causes less overhead to the packets. See the RFC2104 for
4473 * Added new [hmac] configuration section. The SKE used to use
4474 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4475 is of course wrong. The official names that must be proposed in
4476 the SKE are the ones defined in the protocol specification
4477 (hmac-sha1-96 for example). The user can configure any hmac
4478 using any hash function configured in the [hash] section. At
4479 least, the mandatory must be configured.
4481 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4483 * Added HMAC list to the SKE proposal list. It has now both
4484 hash algorithm list and HMAC list. This makes the protocol
4485 incompatible with previous versions. The SKE now seems to work
4486 the way it is supposed to work, for the first time actually.
4488 * Defined plain Hash algorithms to the protocol specification.
4491 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Implemented support for key agreement packets into the server.
4494 Added functions silc_server_key_agreement and
4495 silc_server_send_key_agreement. Other than these functions,
4496 server has nothing to do with this packet.
4498 * Added support for private message key packets into the server.
4499 Added functions silc_server_private_message_key and
4500 silc_server_send_private_message_key.
4504 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4505 called in the protocol's final callback instead in the END
4506 protocol state. This makes a little more sense and in the same
4507 time in client we can use the same protocol routines for normal
4508 key exchange and to key agreement packet handling as well.
4510 * Added to both client's and server's KE protocol context the
4511 SilcSKEKeyMaterial pointer to save the key material. We will
4512 bring the key material to the protocol's final callback by doing
4513 this. The final callback must free the key material.
4515 * Added SKE's packet_send callback into client's KE protocol
4516 context so that the caller can choose what packet sending function
4517 is used. This way we can use different packet sending when
4518 doing normal SKE when doing key agreement packet handling (in
4519 the key agreement packet handling we do not want to encrypt
4522 * Implemented the responder side of the key agreement routines
4523 in the client. The client can now bind to specified port and
4524 accept incoming key negotiation. The key material is passed
4525 to the application after the protocol is over.
4527 * Implemented the processing of incoming Key Agreement packet
4528 in the client. Added function silc_client_key_agreement to
4531 * Implemented the intiator side of the key agreement routines
4532 in the client. The client can now initiate key agreement with
4533 another remote client. The key material is passed to the
4534 application after the protocol is over.
4536 * Created client_keyagr.c to include all the key agreement
4539 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4540 SILC_TASK_CALLBACK except that it is not static.
4542 * Created client_notify.c and moved the Notify packet handling
4543 from the client.[ch] into that file.
4545 * Created client_prvmsg.c and moved all private message and
4546 private message key routines from the client.[ch] into that file.
4548 * Create client_channel.c and moved all channel message and
4549 channel private key routines from the client.[ch] into that file.
4551 * Changed silc_client_get_client_by_id_resolve to resolve with
4552 WHOIS command instead of IDENTIFY command, in the file
4553 lib/silclient/idlist.c.
4555 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Implemented the SKE's responder side to the Client library.
4559 * When FAILURE is received to the protocol do not trust it
4560 blindly. Register a timeout to wait whether the remote closes
4561 the connection as it should do it, only after that process the
4562 actual failure. This was changed to both client and server.
4564 * Added client_internal.h to include some of the structures
4565 there instead of client.h in lib/silcclient/.
4567 * Added function silc_task_unregister_by_callback to unregister
4568 timeouts by the callback function.
4570 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Some "Incomplete WHOIS info" errors has been appearing on the
4573 log files. Took away the entry->userinfo check from WHOIS
4574 reply sending. The entry->userinfo is now " " if client did not
4575 provide one. I thought this was fixed earlier but something
4576 is wrong still. Let's see if the error still appears.
4578 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Fixed a minor bug in the login when the channel key is
4581 re-generated in the server. It used to generate the key in
4582 wrong order and thus caused problems in the channel traffic.
4584 * Fixed a minor bug in channel key distsribution after
4585 KICK command. The key was not sent to the router even though
4588 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added silc_ske_process_key_material_data as generic routine
4591 to process any key material as the SILC protocol dictates. The
4592 function is used by the actual SKE library but can be used by
4593 applications as well. This relates to the private message keys
4594 and the channel private keys since they must be processed the
4595 same way the normal SILC session keys. The protocol dictates
4596 this. Affected files: lib/silcske/silcske.[ch].
4598 Added also silc_ske_free_key_material to free the
4599 SilcSKEKeyMaterial structure.
4601 * Defined silc_cipher_set_key function to set the key for
4602 cipher without using the object's method function. The affected
4603 files: lib/silccrypt/silccipher.[ch].
4605 * Implemented silc silc_client_add_private_message_key,
4606 silc_client_add_private_message_key_ske,
4607 silc_client_del_private_message_key,
4608 silc_client_list_private_message_keys and
4609 silc_client_free_private_message_keys functions in the
4612 Added functions silc_client_send_private_message_key to send
4613 the Private Message Key payload and silc_client_private_message_key
4614 to handle incoming Private Message Key payload.
4616 * Added Cipher field to the Private Message Key payload to set
4617 the cipher to be used. If ignored, the default cipher defined
4618 in the SILC protocol (aes-256-cbc) is used.
4620 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Removed lib/silcclient/ops.h file.
4624 Redefined parts of the SILC Client Library API. Created new
4625 file silcapi.h that deprecates the ops.h file and defines the
4626 published Client Library API. Defined also private message key
4627 API and channel private key API into the file.
4629 This is the file that the application must include from the
4630 SILC Client Library. Other files need not be included by
4631 the application anymore.
4633 * Added new key_agreement client operation callback and also
4634 defined the Key Agreement library API for the application.
4636 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4639 is used by clients to request key negotiation between another
4640 client in the SILC network. If the negotiation is started it
4641 is performed using the SKE protocol. The result of the
4642 negotiation, the secret key material, can be used for example
4643 as private message key.
4645 Implemented the Key Agreement payload into the files
4646 lib/silccore/silauth.[ch].
4648 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Redefined ciphers for the SILC protocol. Added some new ciphers
4651 and defined the key lengths for the algorithms. Changed the
4652 code accordingly. The default key length is now 256 bits.
4654 * Fixed SKE key distribution function silc_ske_process_key_material
4655 when the key length is more than 128 bits. The default key
4656 length in SILC is now 256 bits.
4658 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4659 to indicate unsupported algorithm.
4661 * Renamed rijndael.c to aes.c and all functions as well.
4663 * Fixed a long standing channel key setting bug in client library.
4664 Weird that it has never surfaced before.
4666 * Fixed bug in channel deletion. If the entire channel is removed
4667 then it must also delete the references of the channel entry
4668 from the client's channel list as the client's channel entry and
4669 the channel's client entry share same memory.
4671 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Implemented CONNECT and SHUTDOWN commands in the client.
4675 * Implemented CLOSE command to the client.
4677 * Added the function silc_idlist_find_server_by_name into the
4678 files silcd/idlist.[ch].
4680 Added the function silc_idlist_find_server_by_conn into the
4681 files silcd/idlist.[ch].
4683 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * DIE command was renamed to SHUTDOWN. Updated the both code
4688 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4689 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4691 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4694 * Added function silc_server_create_connection function to create
4695 connection to remote router. My server implementation actually
4696 does not allow router to connect to normal server (it expects
4697 that normal server always initiates the connection to the router)
4698 so the CONNECT command is only good for connecting to another
4701 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4704 or some other client was kicked from the channel.
4706 Implemented the handling of the notify type to both client
4709 Implemented silc_server_send_notify_kicked to send the KICKED
4710 notify. It is used to send it to the server's primary router.
4712 * Implemented the KICK command into server and client.
4714 * Added `query' argument to the silc_idlist_get_client function
4715 to indicate whether to query the client from server or not if
4718 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4719 to indicate that the client is not channel founder.
4723 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Removed the rng context from SilcPacketContext structure and
4726 changed that the packet routine uses the Global RNG API.
4728 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Added support for quit message that client can "leave" on the
4731 channel when it quits the SILC. It is ditributed inside the
4732 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4734 Added silc_server_free_client_data that will take the
4735 signoff message as argument.
4737 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4739 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Updated parts of the protocol specification to keep it up
4744 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4747 payloads in one packet.
4749 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4750 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4751 use now the new List flag.
4753 * Also deprecated the following packet types: REPLACE_ID,
4754 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4756 * Added list support for Notify packet in server.
4758 * Added silc_server_send_notify_channel_change to send the
4759 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4760 the silc_server_send_replace_id.
4762 * Added silc_server_send_notify_nick_change to send the
4763 NICK_CHANGE notify type. Deprecates the function
4764 silc_server_send_replace_id.
4766 * Added silc_server_send_notify_join to send the JOIN notify type.
4767 Deprecates the function silc_server_send_new_channel_user.
4769 * Added silc_server_send_notify_leave to send LEAVE notify type.
4770 Deprecates the function silc_server_send_remove_channel_user.
4772 * Added silc_server_send_notify_cmode and
4773 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4774 types. Deprecates the silc_server_send_set_mode function.
4776 * Added SERVER_SIGNOFF notify type to indicate that server has
4777 quit. This means that all clients on the channel from that
4778 server will drop. This can be also used when netsplit happens.
4780 Deprecated REMOVE_ID packet type since it is not needed anymore
4783 Added silc_server_send_notify_server_signoff to send the
4784 SERVER_SIGNOFF notify type. Deprecates the function
4785 silc_server_send_remove_id.
4787 Added also silc_server_send_notify_signoff to send the
4788 SIGNOFF notify type.
4790 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4791 SILC protocol from this day on. Changed the protocol
4792 specification as well.
4794 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4795 notify type. It is used between routers to notify about
4796 topic changes on a channel.
4798 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4801 * Partly updated the protocol specification to comply with the
4802 changes now made. It is still though a bit outdated.
4804 * The JOIN notify type now takes one extra argument <Channel ID>.
4805 The packet used to be destined to the channel but now the
4806 JOIN type may be sent as list thus it is impossible to
4807 destine it to any specific channel. By adding this argument
4808 it is again possible.
4810 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Added CREDITS file. The CHANGES and CREDITS file will appear
4813 in the distribution as well.
4815 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4818 types in the server's silcd/packet_receive.c.
4820 * Implemented CMODE and CUMODE to work in router environment.
4822 * Fixed minor encoding and decoding buglet from the
4823 lib/silccore/silcmode.c.
4825 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4828 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4830 * Changed all SilcConfigServer* and silc_config_server* to
4831 SilcServerConfig* and silc_server_config*, respectively.
4834 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Associated the ID (client or server ID) to the Authentication
4837 Payload to avoid any possibility of forging. Updated the
4838 protocol specification and the code accordingly.
4840 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * The RSA key length is now save to the RsaKey context in the
4843 key generation process in lib/silccrypt/rsa.c. The key length
4844 is now used to figure out the maximum size of the block allowed
4845 to be encrypted/signed.
4847 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4848 is equivalent to the silc_mp_mp2bin but does not allocate any
4851 * Changed silc_mp_mp2bin API to take length argument. If it is
4852 non-zero then the buffer is allocated that large. If zero, then
4853 the size is approximated using silc_mp_sizeinbase, which however
4856 * Created Global RNG API which is global RNG that application can
4857 initialize. After initializing, any routine anywhere in the
4858 code (including library) can use RNG without allocating a new
4859 RNG object. This was done to allow this sort of use of the
4860 RNG in code that has no chance to allocate RNG object. All
4861 applications currently allocate this and many routines in the
4862 library use this. Affected file lib/silccrypt/silcrng.[ch].
4864 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4865 it to use the Global RNG API.
4867 * Defined Authentication Payload into protocol specification that
4868 is used during SILC session to authenticate entities. It is
4869 used for example by client to authenticate itself to the server
4870 to obtain server operator privileges.
4872 Implemented this payload into the lib/silccore/silcauth.[ch].
4873 Implemented also routines for public key based authentication
4874 as the new protocol specification dictates.
4876 Moved definitions of different authentication methods from
4877 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4879 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4880 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4881 silc_pkcs_verify_with_hash functions into the file
4882 lib/silccrypt/silcpkcs.[ch].
4884 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * The client entry's userinfo pointer must be always valid.
4887 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4888 will fail since it requires the userinfo. Now, the userinfo
4889 is allocated as "" if actual userinfo does not exist. Actually,
4890 it must exist and it is totally Ok to drop client connections
4891 that does not announce the userinfo. However, we will make
4892 this workaround for now.
4894 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4895 to return the remote port by socket.
4897 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4900 SILC_SERVER_PENDING_EXEC and added an new macro
4901 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4902 data or when error occurs while processing the pending command.
4904 Added new argument `destructor' into silc_server_command_pending
4905 and to the SilcServerCommandPending object. This destructor is
4906 now called after calling the pending callback or if error occurs
4907 immediately. If error occurs the actual pending callback won't
4908 be called at all - only the destructor. The destructor may be
4909 NULL if destructor is not needed.
4911 All this applies for client library code as well. Similar
4912 changes were made there as well for the pending commands.
4914 In the client, the application must now allocate the
4915 SilcClientCommandContext with the silc_client_command_alloc
4918 * Added reference counter to the SilcServerCommandContext. Added
4919 function silc_server_command_alloc and silc_server_command_dup
4922 Same type of functions added to the client library for the same
4925 * Removed the cmd_ident from IDListData away since it is now
4926 global for all connections. It is the command identifier used
4927 in command sending and with pending commands. The affected file
4930 * Added reference counter to the SilcSocketConnection objecet to
4931 indicate the usage count of the object. The object won't be
4932 freed untill the reference counter hits zero. Currently only
4933 server uses this, and client ignores it. The client must be
4934 set to use this too later. The affected files are
4935 lib/silccore/silcsockconn.[ch]. Added also the function
4936 silc_socket_dup to increase the reference counter.
4938 This was mainly added because it is possible that the socket
4939 is removed underneath of pending command or other async
4940 operation. Now it won't be free'd and proper DISCONNECTING
4941 flags, etc. can be set to avoid sending data to connection that
4942 is not valid anymore.
4944 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4945 the connection. After that it sets SILC_SET_DISCONNECTED.
4946 It is, however, possible that the socket data is not still freed.
4947 The silc_server_packet_process now checks that data is not
4948 read or written to connection that is DISCONNECTED. The socket
4949 get's freed when the reference counter hits zero.
4951 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Changed the client operation API: channel_message operation's
4954 `sender' is now the client entry of the sender, not the nickname
4955 and the `channel' is the channel entry, not the channel name.
4957 In the private_message operation the `sender' is now also the
4958 client entry of the sender not the nickname.
4960 Affected file is lib/silcclient/ops.h and all applications
4961 using the client operations.
4963 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Moved the calling of ops->connect() from connect_to_server_final
4966 into receive_new_id functin since that is the point when the
4967 client is actually allowed to send traffic to network. The
4968 affected file is lib/silcclient/client.c.
4970 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4973 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4974 (if needs broadcasting) instead of broadcasting the packets one
4975 by one which would make a burst in the network traffic.
4977 * Added `broadcast' argument to the functions in silcd/server.[ch]
4978 silc_server_create_new_channel[_with_id] to indicate whether
4979 to send New Channel packet to primary router.
4981 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Added new function into the silcd/server.[ch] files:
4984 silc_server_create_new_channel_with_id to create new channel with
4985 already existing Channel ID.
4987 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4988 lib/silccore/silcpacket.h. This packet is used t send list of
4989 Set Mode payloads inside one packet. Server uses this to set
4990 the modes for the channels and clients on those channels, that it
4991 announced to the router when it connected to it. The protocol
4992 specification has been updated accordingly.
4994 * The silc_server_new_channel did not handle the packet coming
4995 from normal server as it normally does not send that. However,
4996 when it announces its channels it does send it. Implemented
4997 the support for that.
4999 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5000 into the file lib/silccore/id.h.
5002 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Fixed memory leaks in the functions silc_idlist_del_client,
5005 silc_idlist_del_channel and silc_idlist_del_server in the file
5006 silcd/idlist.c. All of those leaked like a sieve.
5008 * Fixed some small memory leaks in the client's function
5009 silc_client_notify_by_server.
5011 * Added functions into silcd/server.c: silc_server_announce_clients,
5012 silc_server_announce_channels and silc_server_announce_server.
5013 These functions are used by normal and router server to announce
5014 to its primary router about clients, channels and servers (when
5015 router) that we own. This is done after we've connected to the
5018 These functions effectively implements the following packet types:
5019 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5020 and SILC_PACKET_NEW_ID_LIST.
5022 * Added new functions into the silcd/packet_receive.[ch]:
5023 silc_server_new_id_list, silc_server_new_channel_list and
5024 silc_server_new_channel_user_list to handle the incoming
5025 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5027 * Added support of changing Channel ID in the function
5028 silc_server_replace_id. If the server that announces a channel
5029 to the router already exists in the router (with same name but
5030 with different Channel ID), router is responsible to send
5031 Replace ID packet to the server and force the server to change
5032 the Channel ID to the one router has.
5034 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5035 client that the Channel ID has been changed by the router. The
5036 normal server sends this to the client. Client must start using
5037 the new Channel ID as the channel's ID.
5039 Implemented handling of this new type into lib/silcclient/client.c
5040 into the function silc_client_notify_by_server.
5042 * Added new function silc_idlist_replace_channel_id into the files
5043 silcd/idlist.[ch] to replace the Channel ID.
5045 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Call silc_server_command_identify_check always when processing
5048 the IDENTIFY command in silcd/command.c
5050 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5053 send keepalive packets. The packet can be sent by clients,
5054 servers and routers.
5056 Added function silc_socket_set_heartbeat into the file
5057 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5058 If not set, the heartbeat is not performed. The actual
5059 heartbeat is implemented in the low level socket connection
5060 library. However, application is responsible of actually
5063 Added silc_server_send_heartbeat to send the actual heartbeat
5064 packet into silcd/packet_send.[ch]. Server now performs
5065 keepalive with all connections.
5067 * Added silc_task_get_first function into lib/silcutil/silctask.c
5068 to return the timeout task with shortest timeout. There was a bug
5069 in task unregistration that caused problems. TODO has been
5070 updated to include that task system must be rewritten.
5072 * The client library will now resolve the client information when
5073 receiving JOIN notify from server for client that we know but
5074 have incomplete information.
5076 * Rewrote parts of silc_server_remove_from_channels and
5077 silc_server_remove_from_one_channel as they did not remove the
5078 channel in some circumstances even though they should've.
5080 * Encryption problem encountered in server:
5082 The LEAVE command used to send the Channel Key packet to the
5083 router immediately after generating it. However, the code
5084 had earlier sent Remove Channel user packet but not immediately,
5085 ie. it was put to queue. The order of packets in the router
5086 was that Channel Key packet was first and Remove Channel User
5087 packet was second, even though they were encrypted in the
5088 reverse order. For this reason, MAC check failed. Now, this
5089 is fixed by not sending the Channel Key packet immediately but
5090 putting it to queue. However, this is more fundamental problem:
5091 packets that are in queue should actually not be encrypted
5092 because packets that are sent immediately gets encrypted
5093 actually with wrong IV (and thus MAC check fails). So, packets
5094 that are in queue should be encrypted when they are sent to
5095 the wire and not when they put to the queue.
5097 However, the problem is that the current system has not been
5098 designed to work that way. Instead, the packet is encrypted
5099 as soon as possible and left to the queue. The queue is then
5100 just purged into wire. There won't be any fixes for this
5101 any time soon. So, the current semantic for packet sending
5104 o If you send packet to remote host and do not force the send
5105 (the packet will be in queue) then all subsequent packets to the
5106 same remote host must also be put to the queue. Only after the
5107 queue has been purged is it safe again to force the packet
5110 o If you send all packets immediately then it safe to send
5111 any of subsequent packets through the queue, however, after
5112 the first packet is put to queue then any subsequent packets
5113 must also be put to the queue.
5115 Follow these rules and everything works fine.
5117 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Added new function silc_server_remove_clients_by_server to
5120 remove all client entries from ID list when the server connection
5121 is lost. In this case it is also important to invalidate all
5122 client entires as they hold the invalid server entry. This
5123 fixes fatal bug when server has lost connection and will reconnect
5126 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Made some sanity checks to silc_server_daemonise like to check
5129 whether the requested user and group actually exists.
5131 * Added sanity check to SKE's silc_ske_responder_finish to check
5132 that the public and private key actually is valid.
5134 * Invalidate the client's nickname when receiving Replace ID
5135 packet and the Client ID is being replaced. This means that the
5136 server will query the nickname if someone needs it (client)
5139 * Sort the ID Cache in client library when the ID Cache data
5140 has changed (needs sorting).
5142 * Do not allow for SILC client to create several connections to
5143 several servers. The client does not support windows right now
5144 and generating multiple connections causes weird behaviour.
5146 Irssi-silc client does support windows and can handle several
5147 connections without problems, see: www.irssi.org and SILC plugin.
5149 * Fixed some places where client was added to the IDList. The
5150 rule of thumb is following (in order to get everything right):
5151 If the client is directly connected local client then the
5152 `connection' argument must be set and `router' argument must be
5153 NULL to silc_idlist_add_client function. If the client is not
5154 directly connected client then the `router' argument must
5155 bet set and the `connection' argument must be NULL to the
5156 silc_idlist_add_client function.
5158 * The funtion silc_server_packet_send_local_channel actually did
5159 not check whether the client was locally connected or not. It
5160 does that now. Fixed a bug related to LEAVE command.
5162 * Fixed Remove Channel User payload parsing bug in server's
5163 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5165 * The server's silc_server_save_channel_key now checks also the
5166 global ID list for the channel as it might not be in the local
5167 list. Fixed a bug related to LEAVE command.
5169 * Is this the end of the [<unknown>] buglet that has been lurking
5170 around for a long time? A little for loop fix in server's
5171 silc_server_command_whois_parse that is used by both IDENTIFY
5172 and WHOIS command. At least, this was a clear bug and a cause
5173 of one type of [<unknown>] buglet.
5175 * WHOIS and IDENTIFY commands call the function
5176 silc_server_command_[whois/identify]_check function even if
5177 we are not router server.
5179 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Added --with-gmp configuration option. If set the GMP
5182 is always compiled in the SILC source tree. If not set then
5183 it is checked whether the system has the GMP3 installed. If
5184 it has then the GMP won't be compiled (the system's headers
5185 and library is used), if it doesn't have it then the GMP is
5186 compiled in the SILC source tree.
5188 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Changed RSA private exponent generation to what PKCS #1
5191 suggests. We try to find the smallest possible d by doing
5192 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5193 not security fix but optimization.
5195 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Added new config entry [Identity] to fork the server and run
5198 it as specific user and group. A patch from Bostik.
5200 * Imported Dotconf configuration library into lib/dotconf.
5201 This will be used to create the SILC configuration files later.
5202 It will appear in the distsribution after this commit.
5204 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * A big code auditing weekend happening. Auditing code for
5207 obvious mistakes, bugs and errors. Also, removing any code
5210 Removed files for being obsolete:
5212 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5213 inline in the file lib/silcutil/silcbuffer.h)
5215 o lib/silcutil/silcbufutil.c (the header has inline versions)
5217 Changed code to fix possible error conditions:
5219 o The buffer formatting routines now check that the destination
5220 buffer really has enough space to add the data. This applies for
5221 both buffer formatting and unformatting
5222 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5223 unformatting was changed to accomodate following rules:
5224 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5225 sent to the function while XXX_*STRING will not allocate or copy
5226 the data into the buffer. Instead it sets the pointer from the
5227 buffer into the pointer sent as argument (XXX_*STRING used to
5228 require that the pointer must be allocated already). This change
5229 makes this whole thing a bit more consistent and more optimized
5230 (note that the data returned in the unformatting with XXX_*STRING
5231 must not be freed now). The routines return now -1 on error.
5233 o Tried to find all code that use buffer_format and buffer_unformat
5234 and added return value checking to prevent formatting and
5235 especially unformatting errors and possible subsequent fatal
5238 o Changed ske->x and ske->KEY to mallocated pointers in
5239 lib/silcske/silcske.h. Fixed possible data and memory leak.
5241 o Added return value checking to all *_parse* functions. Fixed
5242 many memory leaks as well.
5244 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5245 so that buffer overflows would not happen. All code now also
5246 checks the return value as it can fail.
5248 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Added reconnection support to server if the normal server looses
5251 its connection to the router (for example if router is rebooted).
5252 The server performs normal reconnection strategy implemented
5253 to the server. Affected file silcd/server.c.
5255 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Added new packet type SILC_PACKET_SET_MODE that is used to
5258 distribute the information about changed modes (for clients,
5259 channels and clients channel modes) to all routers in the
5260 network. Updated the protocol specification accordingly.
5262 Added functions into silcd/packet_send.c and
5263 silcd/packet_receive.c: silc_server_send_set_mode,
5264 silc_server_set_mode.
5266 Added new files silcmode.[ch] into lib/silccore that implements
5267 the encoding and decoding of Set Mode Payload. Added new type
5268 SilcSetModePayload. Moved the definitions of different modes
5269 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5271 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Oops, a little mistake in server's connection authentication
5274 protocol. The protocol is not ended with FAILURE but with
5275 SUCCESS if the authentication is Ok. :) Affected file is
5278 * Implemented NICK_CHANGE notify handling in server in the file
5279 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5280 the local clients on the channel. After the changing nickname
5281 in router environment snhould work and the [<unknown>] nickname
5282 should appear no more.
5284 The silc_server_replace_id function that receives the Replace ID
5285 payload now sends the NICK_CHANGE notify type also in the file
5286 silcd/packet_receive.c
5288 * Changed WHOIS and IDENTIFY command to support the maximum amount
5289 of arguments defined in protocol specs (3328 arguments). This
5290 fixed a bug that caused problems when there were more than three
5293 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Added extra parameter, command identifier, to the
5296 silc_client_send_command so that explicit command identifier
5299 Changed that ID list routines uses specific command identifier
5300 when sending WHOIS/IDENTIFY requests to the server so that they
5301 can be identified when the reply comes back.
5303 Affected files lib/silcclient/command.[ch],
5304 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5306 * Added `sender' argument to silc_server_packet_send_to_channel
5307 to indicaet the sender who originally sent the packet to us
5308 that we are now re-sending. Ignored if NULL. Affected file
5309 silcd/packet_send.[ch].
5311 * Added some server statistics support in silcd/server_internal.h
5312 SilcServerStatistics structure and around the server code. Also
5313 send some nice statistics information when client is connecting
5316 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Fixed channel ID decoding in server's JOIN command reply in
5319 silcd/command_reply.c
5321 * Fixed braodcasting of replace ID payload to not to send it if
5322 we are standalone server in silcd/packet_receive.c.
5324 * Fixed all channel message sending routines to not to send
5325 packets to clients that has router set, since they are routed
5326 separately in the same function earlier. Affects file
5327 silcd/packet_send.c and all channel packet sending functions.
5329 * In USERS reply, res_argv[i] are not allocated, the table
5330 is allocated. Thus changed that free the table, not its
5333 * In server's whois_check and identify_check if the client is
5334 locally connected do not send any WHOIS commands - they are not
5337 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Fixed some minor bugs in client when sending WHOIS command. The
5340 arguments was in wrong order.
5342 * Removed statis function add_to_channel from server in
5343 silcd/command.c that was previously used with the joining but
5346 * Tested USERS command in router environment successfully with two
5347 routers, two servers and two clients.
5349 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Reorganized the USERS command and command reply in client library
5352 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5353 When the command is given by user we register a pending command
5354 callback that will reprocess the command after the reply has been
5355 received from the server. When reprocessing the packet we then
5356 display the information. Thus, the USERS information is displayed
5357 now in the command callback instead of in the command reply
5358 callback. The processing of the command is same as previously
5359 when server has sent the command reply in the JOINing process.
5361 * Added to USERS command in silcd/command_reply.c to join the client,
5362 we didn't use to know about, to the channel after we've created
5363 a client entry for it. Also, for clienet we did know already still
5364 check whether it is on the channel or not and add it if not.
5366 * Removed silc_server_command_join_notify as the function and its
5369 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Changed the client's pending command handling to the same as the
5372 server's pending command handling. It is also now possible to
5373 execute command reply functions from other command reply
5374 function as the function callbacks for commands and command
5375 replies are one and same. The pending commands are not static
5376 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5377 in client connection context. Thus, pending commands are server
5378 connection specific as it is convenient.
5380 Changed the function silc_client_command_pending and
5381 silc_client_command_pending_del and added new function
5382 silc_client_command_pending_check. Removed the
5383 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5386 * Added cmd_ident, current command identifier, to the client
5387 connection context in lib/silcclient/client.h to keep track on
5388 command identifiers used in command sending. Client's command reply
5389 function handling now supports the mandatory command identifiers.
5391 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5392 funtions in client to fully support pending command callbacks.
5394 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5395 as one of the arguments to the application in the command reply
5398 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5399 before first releasing SILC but came back. Now it is removed again
5400 and should come back nomore. The FORWARDED flag was used only
5401 by the JOINing procedure by forwarding the command packet to router.
5402 Now, the JOINing procedure has been changed to more generic (due
5403 to various router environment issues) and FORWARDED is not needed
5404 anymore for anything. The protocol specification is yet to be
5407 Now, removed silc_server_packet_forward from server and the flag
5408 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5410 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Renamed NAMES command to USERS command. The NAMES was named that
5413 due to historical reasons. Now it is renamed. Also, rewrote
5414 parts of the USERS command. The nickname list is not sent anymore
5415 by the server. Only Client ID and mode lists are sent in the USERS
5416 command. Changed this also to the protocol specification.
5418 The client now resolves the names and stuff after it receives
5419 the USERS list from the server when joining to the channel.
5421 * WHOIS and IDENTIFY commands has been changed to support multiple
5422 Client ID's per command. One can now search for multiple users
5423 in the network by sending only one WHOIS or IDENTIFY command.
5424 Changed the code and the protocol specifications.
5426 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5427 uses silc_server_command_whois_parse to parse the request. */
5429 * If normal server, do not parse the WHOIS and IDENTIFY requests
5430 before sending it to the router. Saves some time.
5432 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Fixed JOIN command on client library. Wrong number of arguments
5435 used to crash the client.
5437 * Added silc_server_channel_has_global function to check whether
5438 channel has global users or not.
5440 * Added silc_server_channel_has_local function to check whether channel
5441 has locally connected clients on the channel.
5443 * The silc_server_remove_from_one_channel now checks whether the
5444 channel has global users or not after given client was removed from
5445 the channel. It also checks whether the channel has local clients
5446 on the channel anymore. If it does not have then the channel entry
5447 is removed as it is not needed anymore.
5449 * The silc_server_notify now checks on JOIN notify whether the joining
5450 client is one of locally connected or global. If it is global then
5451 the channel has now global users on the channel and that is marked
5452 to the channel entry. Also, it now saves the global client to
5453 global list who is joining and JOINs it to the channel. This is
5454 for normal server, that is.
5456 Changed silc_server_send_notify_on_channel,
5457 silc_server_packet_relay_to_channel and
5458 silc_server_packet_send_to_channel check if we are normal server
5459 and client has router set (ie. global client) do not send the
5460 message to that client, as it is already routed to our router.
5462 * Implemented LEAVE notify type handling in silc_server_notify
5465 * Tested LEAVE command in router environment successfully. Tested
5466 with two routers, two servers and two clients.
5470 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5472 * Implemented SIGNOFF notify type handling in silc_server_notify
5475 * silc_server_remove_id now removes the client entry from all channels
5476 it has joined and thusly sends SIGNOFF notify type.
5478 * Rewrote the NAMES list generation in server by removing two excess
5479 loops. The lists are created now inside one loop.
5481 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * silc_server_remove_channel_user checks now also global list
5484 for channel and client.
5486 * silc_server_new_channel_user checks now both local and global
5487 list for channel and client. Fixed a bug in client id decoding.
5488 Used to decode wrong buffer.
5490 * silc_server_channel_message checks now both local and global
5491 list for channel entry.
5493 * Tested channel joining (hence JOIN) in router environment
5494 successfully. Tested with two routers, two servers and two
5497 * Tested channel message sending in router environment successfully.
5499 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Added silc_server_save_channel_key into server.[ch] to save the
5502 received channel key in Channel Key payload processing. It is
5503 also used in JOIN command reply handling.
5505 Equivalent function silc_client_save_channel_key added into
5506 client.[ch] into client library.
5508 * Changed JOIN command reply to send information whether the channel
5509 was created or not (is existing already) and the channel key
5510 payload. Changed protocol specs accordingly.
5512 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5513 the request was sent by ID and not by nickname. Crashed on
5516 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5519 now correctly save the received data.
5521 * silc_server_free_sock_user_data now notifies routers in the
5522 network about entities leaving the network.
5524 At the same time implemented functions silc_server_remove_id
5525 and silc_server_send_remove_id to receive and send REMOVE_ID
5526 packets. The packet is used to notify routers in the network
5527 about leaving entities. The ID removed will become invalid in
5530 * Added function silc_idlist_del_server into server. Removes and
5531 free's server entry from ID list.
5533 * silc_server_private_message function now checks, if we are router,
5534 that the destination ID really is valid ID, naturally.
5536 * In router when NEW_ID packet is received (for new client) the
5537 hash of the Client ID is saved in the ID Cache but the
5538 client->nickname is set to NULL, instead of putting the hash
5541 IDENTIFY command now also checks that client->nickname must be
5542 valid. If it is not if will request the data from the server who
5543 owns the client. Added new function
5544 silc_server_command_identify_check.
5546 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5547 to set the command to already allocated Command Payload.
5549 * Tested private message sending in router environment with two
5550 routers, two servers and two clients. Fixed minor bugs and now
5553 * Fixed segfault from client's NAMES command. Used to crash if
5556 * Forwarded packets must not be routed even if it is not destined
5557 to the receiver. Changed server code comply with this.
5559 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Added `require_reverse_mapping' boolean value to ServerParams
5562 structure. If TRUE (not default) the server will require that
5563 the connecting host has fully qualified domain name.
5565 If the reverse mapping is not required and hostname could not be
5566 found the IP address is used as hostname.
5568 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Implemented version string checking to both client and server.
5571 The check is incomplete currently due to the abnormal version
5572 strings used in development version of SILC.
5574 * Changed all command functions in server to use the new
5577 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Changed char *data to unsigned char *data in ID Cache system to
5580 support binary data as ID Cache data. Changed code to support
5581 binary data in lib/silccore/idcache.c.
5583 * Renamed silc_server_packet_relay_command_reply to
5584 silc_server_command_reply as it is normal packet receiving
5585 function. Rewrote the function to accept command replys for
5586 servers and not only for clients.
5588 * Mark remote router always as registered server if we are connecting
5589 to it. Otherwise, commands sent by the router to us are ignored.
5591 * All ID List find routines now returns the ID Cache Entry pointer
5592 as well if requested.
5594 * WHOIS command works now in router environment, tested with two
5595 routers, two servers and two clients.
5597 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5598 in router environment (as it is almost equivalent to WHOIS) but
5599 hasn't been tested thoroughly. Added new functions:
5601 silc_server_command_identify_parse
5602 silc_server_command_identify_send_reply
5603 silc_server_command_identify_from_client
5604 silc_server_command_identify_from_server
5606 * Disabled route cache adding because adding two different ID's with
5607 same IP replaces the old cache entry thus giving wrong route.
5608 The entry->router->connection is always the fastest route anyway
5609 so route cache may not be needed. Of course, new routes maybe
5610 established after receiving the ID when the entry->router->connection
5611 might not be anymore the most optimal.
5613 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Add route cache for received ID for fast routing.
5617 * Added silc_server_packet_route to route received packet on router
5618 that is not destined to us.
5620 * Renamed silc_server_get_route to silc_server_route_get.
5622 * Added id_string and id_string_len fields into SilcServer to
5623 include encoded ServerID for fast comparing without excess
5624 encoding of the ID's.
5626 * Cleaned up WHOIS command on server side. Added following static
5629 silc_server_command_whois_parse
5630 silc_server_command_whois_check
5631 silc_server_command_whois_send_reply
5632 silc_server_command_whois_from_client
5633 silc_server_command_whois_from_server
5635 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5636 arguments in command replies. All command functions should be
5637 updated to use this macro.
5639 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Minor typo fixes on command reply handling on server.
5643 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added silc_server_command_add_to_channel internal routine to add
5646 the client to the channel after router has created the channel and
5647 sent command reply to the server.
5649 * Added generic silc_server_send_command to send any command from
5652 * Use static buffer with ID rendering instead of duplicating data.
5654 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5656 * Fixed a channel user mode bug when joining to a channel server gave
5657 everybody channel founder rights, oops.
5659 * We mark ourselves as the router of the incoming server connection
5660 if we are router ourselves. This way we can check in some packet
5661 sending functions whether it is locally connected server. For
5662 incoming router connections we put NULL.
5664 * For router sending packets locally means now always sending the
5665 packet cell wide; to local clients and local servers. For normal
5666 server sending packet locally means sending it to only local
5669 * Fixed the JOIN command to really work in router environment. If the
5670 channel is created it is always created by the router. Router is
5671 also responsible of making the initial joining to the channel,
5672 sending JOIN notify to the sending server and distributing
5673 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5674 does not exist server doesn't do anything else but forward the
5675 command to the router which performs everything.
5677 * Added silc_server_send_channel_key function to send the Channel Key
5680 * Added silc_server_create_channel_key to create new channel key. The
5681 channel key is now re-generated everytime someone joins or leaves
5682 a channel, as protocol dictates. Note: channel->key_len is the
5685 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5688 packet_receive.[ch] to separate packet sending and receiving
5689 routines. The server.[ch] now includes everything else including
5690 actual packet processing (writing and reading data) and other
5693 Renamed silc_server_private_message_send_internal to
5694 silc_server_send_private_message. The routine is still though
5695 used only to relay private messages as server does not send
5696 private messages itself.
5698 Renamed silc_server_new_channel to silc_server_create_new_channel
5699 and added new function sicl_server_new_channel that handles the
5700 incoming New Channel packet. Added also new sending function
5701 silc_server_send_new_channel to send New Channel Payload.
5703 * Added new function silc_server_notify to process incoming notify
5704 packet to the server/router. Server may then relay the notify
5705 to clients if needed.
5707 * Added new function silc_server_new_channel_user to process incoming
5708 New Channel User packet. Router will redistribute the packet and
5709 send JOIN notify to its local clients and locally connected servers
5710 if needed. Normal server will send JOIN notify to its local client
5711 on same channel when received this packet. Added also corresponding
5712 sending function silc_server_send_new_channel_user to sent the
5715 * Added boolean route argument to send_notif_to_channel and
5716 packet_send_to_channel functions to attempt to route the packet
5717 if it is TRUE and send only locally if it is FALSE.
5719 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * silc_server_replace_id now broadcasts the received replace ID
5722 packet if it is not broadcast packet already. The router must
5723 broadcast to inform other routers about changed ID.
5725 * Added backpointer to server's router into SilcServer context in
5726 silcd/server_internal.h.
5728 * Fixed silc_server_packet_broadcast to send correct broadcast
5731 * The channel key is now distributed to the local client as soon
5732 as it is received from the router (in router environment) so that
5733 no other packet may be sent for the channel until client has
5736 * silc_server_remove_channel_user now broadcasts the received
5737 Remove Channel User packet if it is not broadcast packet already.
5738 The router must broadcast to inform other routers about removed
5741 * Added users field into SilcPacketContext that is a reference count
5742 of the context. One can increase the reference count by calling
5743 silc_packet_context_dup which is now changed to just increase the
5744 reference count instead of duplicating the data. The reference
5745 count is decresed by calling silc_packet_context_free that will
5746 free the data after the reference count hits zero.
5748 For now on the packet context and everything allocated into it
5749 (including the raw packet from network) must be freed by calling
5750 the new silc_packet_context_free function. Added also new function
5751 silc_packet_context_alloc that must be used now to allocate the
5752 context. This also means that if a routine is asynchronous from
5753 silc_[client/server]_packet_parse_type the packet context must
5754 be duplicated by calling silc_packet_context_dup. Otherwise it
5755 gets free'd after silc_[client/server]_packet_parse_type returns.
5756 Also, one must remember that if packet is duplicated then its
5757 reference count must be decresed by calling the free function as
5758 many times as it was duplicated.
5760 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5761 from both client and server.
5763 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Made joining to a channel working in router environment.
5767 * Cleaned up JOIN command on server side and create function
5768 silc_server_command_join_channel internal routine to make the
5771 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Changed silc_command_pending list to SilcDList. Also, added
5774 `ident' field to SilcServerCommandPending structure to identify
5775 the reply and to call correct callback.
5777 Added silc_server_command_pending_check function to replace the
5778 corresnponding macro. The silc_command_pending list is not
5781 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5782 to set identifier to previously allocated Command Payload. It
5783 is used to set identifier for command when resending Command
5786 * Added silc_command_payload_encode_payload to encode Command
5787 Payload buffer from SilcCommandPayload structure.
5789 * Added silc_argument_payload_encode_payload to encode Argument
5790 payload buffer from SilcArgumentPayload structure.
5792 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Changed WHOIS command to support router connection on server side.
5795 The whois request is always sent to router unless the server is
5796 standalone server. After server has received the reply from the
5797 router will it send the reply to the client.
5799 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5800 broadcast received broadcast packet. The function is used only
5801 by router. The broadcast packet is always sent to the router's
5804 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5805 render given ID to printable string, for log files for example.
5807 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Made basic router to router connections working. At least they
5810 can now connect to each other but nothing really works the way
5811 they are supposed - yet.
5813 * Added new initiator token to RouterConnection configuration
5814 file in silcd/serverconfig.[ch]. It is used to tell whether we
5815 are the initiator to the remote router or whether we'll expect
5816 the other end to connect.
5818 * Moved registering of listener task to silc_server_init, hence
5819 the server starts listenning as soon as it is run, even if it
5820 does not have connections to other routers. Let's see how well
5823 * Changed default connection retry timeouts for more suitable in
5826 * Removed cipher and such arguments from silc_idlist_add_client
5827 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5828 Added new function silc_idlist_add_data to add the keys and stuff
5831 * Added SilcIDListData structure and added it to SilcClientEntry
5832 and SilcServerEntry as their first field in the structure. This
5833 way we can explicitly cast the ID entries to the SilcIDListData
5834 structure and get common data for the entries. In past, we had
5835 to first check what type of connection it is and then cast it to
5836 correct ID entry type. Now, we can directly cast the opaque
5837 pointer to the SilcIDListData (no matter what ID entry it actually
5838 is) and get the data needed.
5840 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5843 in some circumstances even if threre were timeout tasks, though not
5844 IO tasks, but tasks anyway. Now fixed.
5846 * Defined SilcServerConnection structure to hold connection specific
5847 stuff about directly connected servers and routers. The definition
5848 is currently in silcd/server_internal.h. I thought about having
5849 a bit more important role fro this struct but for now it is used
5850 only when connecting to other server (or router actually).
5852 * Added connecting retry support in server when connecting to
5853 router(s). The retry feature implement exponential backoff
5854 algorithm. Also, added SilcServerParams structure to hold default
5855 parameters for server. For now, it include these retry settings
5856 and are hard coded. After server is moded to be as Silc Server
5857 Library this structure will be more important.
5859 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Changed client librarys channel->clients table to SilcList and
5862 changed code accordingly.
5864 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Changed client's channel table to SilcList and changed code
5867 accordingly. Also changed SilcChannelClientEntry to include back-
5868 pointer to the channel so that client entry can use that structure
5869 as list as well and we have fast cross-reference to the channel.
5870 This change dramatically decreased the complexity of channel
5871 handling with client entry and vice versa (removed one extra
5872 loop when searching for channel entry from many functions).
5874 * Changed server->sim from table to SilcDList and changed code
5877 * NAMES command can now be used from user interface. It will show
5878 the user list on the channel, neatly.
5880 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5881 Code now saves realname of the user if it becomes available.
5883 * Renamed configure.in to configure.in.pre and made ./prepare
5884 script to automatically add correct version string to
5885 configure.in which it creates from configure.in.pre.
5887 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * NAMES command reply now shows users mode with the nickname when
5892 * Moved silc_client_ch[u]mode[_char] functions from
5893 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5894 place sucks, they are utility functions and should be in some
5897 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5899 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5902 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added TRQ (efficient deque and list library) into lib/trq. This is
5907 a very good list library that is currently used in the SILC. Defined
5908 SilcList API over the library because I didn't like the API very
5909 much. See lib/trq/silclist.h for the API and examples of how to
5910 use the API. Fixed various places in the code to use the new
5911 SilcList API. The SilcList is meant for lists that has a structure
5912 already defined as a list. It is not suitable to add just some
5913 context to the list (in TRQ, the context is the list actually).
5915 So, I defined SilcDList that can be used for the purpose where
5916 predefined list structure does not exit. This can be used as
5917 such list. Now some context just can be added to the SilcDList.
5918 Currently this list is not used in the SILC just yet, though there
5919 are a lot places where this can replace dynamically allocated
5920 tables and I will fix these places, later, to use SilcDList.
5921 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5922 and use TRQ internally).
5924 Also fixed some annoying warning messages that the original TRQ
5925 code generated. Also minor changes to TRQ's Makefile.in.
5927 * Added support for querying by Client ID to both WHOIS and
5928 IDENTIFY commands into server, as required by the protocol.
5930 * Removed method function pointers from SilcBuffer structure. They
5931 weren't used to anything and just increased the context size for
5932 no good reason. This change also made silc_buffer_alloc and
5933 silc_buffer_free functions inline functions.
5935 * Disabled command flooding detection support until it's fixed so
5936 that it accepts commands in but does not execute them more than once
5939 * Added silc_net_localhost(), to return local hostname, into
5940 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5941 that must be initialized before calling silc_client_init.
5943 * Added new function: silc_server_send_notify_on_channels to send
5944 notify messages to all channels client has joined. It is assured
5945 that the message is sent only once per client.
5947 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5948 lib/silcutil/silcutil.[ch] as silc_format function. The new
5949 function is generic and is used by server as well, not only by
5950 the logging routines.
5952 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5953 the provided version string was not acceptable. Added new function:
5954 silc_ske_check_version into lib/silcske/silcske.h. The function
5955 must be implemented by the application (client or server) and it
5956 does not reside in the SKE library. The function checks the version
5957 string remote end sent.
5959 * Added back pointers (to opaque context and to SilcSocketConnection)
5960 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5962 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5963 duplicate packet context structure.
5965 * Changed `notify' client operation to send same arguments as client
5966 receives from server except for ID's. ID's are mapped to correct
5967 ID entry and that is returned. Also, if channel entry is not sent
5968 by server but the notify is for channel the channel entry is sent
5969 to application (otherwise application doesn't know that it is for
5970 channel (library gets it from packet's Destination ID)).
5972 * Added silc_client_remove_from_channels into client library to
5973 remove a client from all channels it has joined to. Used when
5974 received SIGNOFF notify from server. Added also new function
5975 silc_client_replace_from_channels to replace old ID entry with
5976 new ID entry on all channels. Used when received NICK_CHANGE
5979 * Fixed ID Cache list handling in silc_idlist_get_client in
5980 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5981 to get (or query) client by ID.
5983 * Updated TODO list.
5985 * Added connection authentication status message defined by the
5986 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5987 support for these into the code in client and server side.
5989 * Added generic function silc_client_send_command to send any command
5990 with variable argument list. Application should use this function
5991 to send commands if the command functions provided by the library
5992 does not suite for the application's user interface needs.
5994 * Added new `failure' client operation. Application is notified about
5995 received failure packet if client is executing a protocol. In this
5996 case the protocol's execution has failed.
5998 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5999 is required by the protocol.
6001 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6002 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6005 * Added status flag to SilcSKE object to indicate realtime status
6006 of the SKE protocol.
6008 * Application receives now exactly same command reply arguments as
6009 the library receives from server. However, if ID is received the
6010 corresponding ID entry is returned to the application (eg. Client
6011 ID is mapped to correct SilcClientEntry entry and that is returned).
6012 Changed command_reply client operation due to this change.
6014 * Changed all ID's in commands and in command replys as ID Payloads.
6015 Change affected both client and server side codes.
6017 All ID's sent in SILC network (with execption of ID's in SILC
6018 Packet header) are sent in ID Payload to support variable length
6021 * Server now notifies nick changes and notifies all clients on
6022 the channels about the new nickname (about the new Client ID,
6025 * Implemented CMODE command to change channel modes. Supports all
6026 channel modes defined by the protocol specs except ban and invite
6027 lists. (Also, private channel key mode is supported but support for
6028 setting private channel key in client is missing, thus, this mode
6029 has no effect on client side (except that server requires that the
6030 client uses private channel key and normal channel traffic does not
6033 Also, invite mode works per se, but INVITE command does not work
6034 yet correctly, so you can set channel as invite only channel but
6035 inviting clients to the channel does not work (it is yet to be
6036 thought what's the best way to do it).
6038 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6039 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6040 Implemented CUMODE command to change user's mode on the channel.
6041 Supports all modes defined by the protocol specs.
6043 * Added NAMES command reply to return users modes on the channel.
6045 * Removed unnecessary and slow ciphers from lib/silccrypt.
6047 * Set SO_KEEPALIVE option to connection sockets by default.
6049 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6051 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6052 redefined the Notify Payload into protocol specs.
6054 * Added silc_id_payload_parse_id to get ID directly from raw
6057 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6060 accept searching by Client ID as well.
6062 * Added support for LEAVE and SIGNOFF notify types in client library.
6064 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6065 to parse ID Payload from raw data.
6067 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Added flags parameter into silc_ske_assemble_security_properties
6070 function in lib/silcske/silcske.[ch].
6072 * Changed notify client operation to fit better for notify messages
6073 sent by server. The notify payload received from server is now
6074 passed to the application (after parsing it to SilcNotifyPayload).
6075 It is application's responsibility to retrieve the arguments
6076 from the payload and show the message the way it wants. The message
6077 sent by server is implementation specific.
6079 * Changed public keys to comply with the protocol specification.
6080 Old public keys are not supported anymore and are not compatible.
6082 * Removed nickname from Channel Payload as the latest draft removed
6083 it. The client must resolve the nickname from the NAMES command
6084 reply received when it joined the channel.
6086 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6088 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Fixed some errors in protocol specification drafts.
6092 * Created lib/silccore/silcnotify.c to implement Notify Payload
6093 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6094 generic payloads described by protocol specifications. The file
6095 includes implementations for ID Payload and Argument Payload.
6097 * Changed Command Payload implementation to use the new Argument
6098 Payload. Changed command_xxxx_payload to command_payload_xxxx
6099 to comply with SILC coding conventions.
6101 * Added suppport for Argument Payload handling in Notify Payload
6102 implementation as protocol requires it. Added the new support
6103 into server and client lib as well.
6105 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Added support for multiple nicknames on same channel. [n] is
6108 added locally to the nickname if there are more than one same
6109 nicknames on the channel.
6111 * Server now sends all nicknames that matched WHOIS request.
6112 Client also shows the list received from server.
6114 * Added TOPIC command to client side. User can now set and show
6115 current topic on channel.
6117 * Added MOTD command to client and server. Also, server sends the
6118 motd when client connects to the server.
6120 * Changed version strings to comply ISO 8601.
6122 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Fixed protocol error handling in client library. It should now
6125 cope even if the SKE fails for some reason.
6127 * Made new protocol specification drafts for submitting to IETF.
6129 * Implemented TOPIC command to server in silcd/command.c.
6131 * Added two new notify types into lib/silccore/silcnotify.h:
6132 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6133 notify nickname change and topic setting/change on a channel.
6135 * API change of command_reply operation in client library. The
6136 application gets now the status type received from server as well.
6138 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6142 * Cras fixed and optimized the packet handling even further and
6143 it should work now. Minor change to the prototype of function
6144 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6146 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Added new function into lib/silcutil/silcschedule.[ch]:
6149 silc_schedule_with_fd to select() a specified fd. The function
6150 returns after timeout expires or data arrives or goes. The
6151 function is used by packet routines to wait that all data is
6152 received from network.
6154 * Fixed data reading from network in lib/silccore/silcpacket.c.
6155 The code now assures that all data is read from the fd and then
6156 continues packet processing. This was a bug fix since the code
6157 used to drop some data in some circumstances.
6159 * Added new function into lib/silcclient/client.[ch]:
6160 silc_client_start_key_exchange to start key exchange after
6161 connection has been established to server. The code internally
6162 now uses this funtion but its main purpose was to provide it
6163 for applications that perform their own connecting. After
6164 application has created a connection it merely calls this
6165 function to start the key exchange between client and server.
6166 The library takes care of everything else after that.
6168 Updated also lib/silcclient/README to explain the usage of
6171 * Do not send to application information that connection has
6172 been established. Application gets notified it by connect
6175 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Applied cras's patch to add silc_schedule_one function. The
6178 function runs scheduler once and returns.
6180 * Fixed the scheduler after cras messed it up. The timeout
6181 handling works now as it's supposed to work.
6183 * Added into lib/silccore/ silcnotify.h to include notify
6184 message types support. Changed silc_server_send_notify*
6185 functions, in server.[ch], to support those new notify types.
6186 Added the support for the notify types into client library,
6187 as well. Added new notify client operation into ops.h in
6190 * Changed silc_server_packet_send_to_channel to send normal
6191 packets instead of just channel message packets. The function
6192 is now used to send the notify packets to channels. It is not
6193 used to send channel message packets anymore, as server never
6196 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6197 va_arg()s as it seems to require it nowadays. I guess, if SILC
6198 is compiled with older va_arg() the new code should work anyway.
6200 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Splitted core library. Core library (lib/silccore) includes
6203 now only SILC protocol specific core (and common) components.
6204 Created new utility library (lib/silcutil) that includes more
6205 generic purpose stuff. The stuff for util library was taken
6206 from the old core library. This was minor and easy split.
6208 * Created SILC Client Library (lib/silcclient) that includes
6209 implementation of the SILC client without user interface. This
6210 was major move from silc/ directory. The code has been changed
6211 so that it is transparent towards the user interface. The
6212 silc/ directory includes now the same user interface as before
6213 and it uses the new client library. Read lib/silcclient/README.
6214 Basicly, the client library performs everything else related
6215 to SILC except user interface handling. Also, configuration
6216 files are considered to be part of user interface and library
6217 does not handle them.
6219 This change also changed a lot of structures, function naming etc.
6220 Most important change was that SilcClientWindow object was
6221 renamed to SilcClientConnection in the client library. Created
6222 also new file lib/silcclient/ops.h. Also added new files
6223 silc/local_command.[ch] and silc/client_ops.[ch].
6225 All these changes were made to make it easier for user interface
6226 designers to create what ever user interface for the SILC client
6229 It is also expected that the server will be moved to lib
6230 directory as well and SILC Server Library will be created;
6231 sometimes in the future.
6233 * Removed Local commands from lib/silccore/silccommand.h as
6234 they are application specific and new client library does not
6235 handle any of those anymore.
6237 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6238 old client implementation in silc/.
6240 * Added support for callback functions in SILC_LOG_* macros.
6241 Application can now set its own callbacks that will be called
6242 instead of using the default functions that will always print
6243 the debug messages to stderr (or stdout). Also, debugging can
6244 now be disabled by setting silc_debug to FALSE and re-enabled by
6245 setting it to TRUE. Note, that logging will still work even
6246 if debugging is disabled.
6248 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6249 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6250 silc_log_reset_debug_callbacks.
6252 * To enable debugging in silc client one must give now -d
6253 option on command line.
6255 * Changed silc_schedule_init to automatically allocate task queues
6256 if they are not allocated before calling it.
6258 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Added GMP 3.1 into math library.
6262 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6265 a channel in SILC network. The packet is used by servers and
6266 routers to notify other routers that user has left a channel.
6267 This little feature was missing until now. Added the feature
6268 to protocol specification as well.
6270 Added functions: silc_server_send_remove_channel_user and
6271 silc_server_remove_channel_user into server.[ch].
6273 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6274 lib/silccore/silcpacket.h. However, they are not implemented
6277 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Fixed joining to a channel and sending channel messages
6280 between server and router. The channel message sending should
6281 now work inside a cell.
6283 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Fixed the private message sending between server and router.
6286 The private message sending should now work inside a cell.
6288 * Added silc_server_replace_id into server.[ch] to replace
6289 existing ID in the SILC network.
6291 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6292 and silc_idlist_replace_server_id into idlist.[ch] in server.
6294 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Fixed the server to server connections. Server can again now
6297 connect to router. Router to router connections probably does
6300 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Added dynamic protocol registering support. Now protocols can
6303 registered and unregistered on the fly. Patch by cras.
6305 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Added lib/contrib directory to hold routines that some platforms
6308 don't have but are needed by SILC.
6310 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6311 into lin/contrib to provide getopt() and getopt_long() for
6312 those who don't have it.
6314 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Added AWAY command to client. When away message is set and
6317 client receives a private message packet the client automatically
6318 replies to the sender with the away message.
6320 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6321 bug seemed to be the cause of recent problems when compiling
6324 * Added version detection support to SKE protocol specification
6325 and added the new changes to the SKE implementation as well.
6326 There were other minor changes in the SKE protocol as well.
6328 Many changes in lib/silcske/silcske.[ch] and in
6329 lib/silcske/payload.[ch].
6331 * Added ^U functionality, clear input line. Patch from cras.
6333 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Mainly small bugfixes on core library. Fixed some debugging
6336 logging and buffer overflow in silclog.c.
6338 * Updated config.sub and config.guess on the distribution tree.
6340 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Added command lagging support in server. Client may execute
6343 commands now only once in two seconds.
6345 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Optimized packet reception. MAC computation and checking is now
6348 also more optimized. A lot previously duplicated code is now
6349 used as generic by both client and server.
6351 * Fixed key pair generation in clientutil.c
6353 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Added into lib/silccore/silcbufutil.[ch] new function;
6356 silc_buffer_realloc.
6358 * Moved generic packet sending/encryption functions to
6359 lib/silccore/silcpacket.[ch] from client and server. Some
6360 rewriting of the functions.
6362 * Moved all generic packet reception/decryption functions to
6363 lib/silccore/silcpacket.[ch] from client and server. The
6364 packet processing is now much cleaner in both client and server.
6365 These were major changes in both client and server.
6367 * Created many common functions in server to do packet sending.
6368 Previously code were duplicated a lot, this has been removed
6371 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6373 * Rewrote major parts of the ID cache system. Don't know
6374 whether it is better now or not but at least the API is more
6377 * Major rewrite on ID cache stuff on client because of the ID
6378 cache API changes. Added idlist.c to client.
6380 * Also major rewrite on ID cache stuff on server as well.
6381 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6382 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6383 in hand, instead they are all put into the ID cache system now.
6384 All server_idlist_* routines uses ID cache now instead of
6385 traversing its own lists (those lists does not exist anymore).
6386 SilcIDList though still exists. Also, SilcXXXEntry's are
6389 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6391 * Finally made the SKE implementation compliant to the protocol
6392 specification. All mp integers are now binary encoded as
6393 opposed being HEX encoded.
6395 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6398 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6399 functions: silc_[encode/decode]_pem. Also added function
6400 silc_encode_pem_file to PEM encode with newlines ('\n') for
6403 * SILC public keys are now encoded either PEM or binary. Same
6404 option is for private keys as well. By default private keys
6405 are binary encoded and public keys PEM encoded. Silly HEX
6406 encoding were removed.
6408 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6409 function to create fingerprints.
6411 * Fixed a bug in SHA1; does not change the original data anymore.
6413 * Partly implemented INFO command on client and server side.
6414 Fixed CLEAR command. Changes to SERVER command; show current
6415 server(s) when giving command without arguments. Added
6416 VERSION command to client.
6418 * Added check to server that unregistered connections cannot
6419 execute commands (unless it is specificly allowed).
6421 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Fixed screen refresh.
6425 * Fixed channel joining bug from client. On some circumstances
6426 client tried to join to a channel it had already joined.
6428 * Added public key verification process into client's protocol.c.
6429 The client now verifies the public key from user and saves
6430 it into ~./silc/serverkeys/ directory.
6432 Added into: clientutil.[ch]: silc_client_verify_server_key.
6434 * Changed SKE protocol's silc_ske_initiator_finish function
6435 to accept callback function that verifies the received public
6436 key. Removed old silc_ske_verify_public_key function.
6438 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6441 silc_pkcs_private_key[_data]_set.
6443 * Made the password and public authentication more cleaner in
6444 server's protocol.c.
6446 * Removed historic and obsolete protocol `channel_auth' from
6447 both client and server.
6449 * Removed wrong way of sending command status messages from
6450 server to client in server's command.c. The old way violated
6451 protocol specification.
6453 Changes to silccore/silccommand.[ch]: removed
6454 silc_command_encode_status_payload -> not needed anymore,
6455 changed silc_command_encode_payload_va to accept extra
6456 argument on variable argument list. The argument type must
6457 now be provided to the function. Also, added new function:
6458 silc_command_encode_reply_payload_va which is same as
6459 normal command_encode_payload_va except command status type
6460 is provided as extra argument.
6462 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added ~./silc directory handling. The directory includes the
6465 public and private keys for the client.
6467 Added silc_client_check_silc_dir, silc_client_create_identifier
6468 and silc_client_load_keys.
6470 * Implemented SILC protocol compliant public key. Added public
6471 and private key saving to and loading from files.
6473 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6474 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6475 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6476 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6477 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6479 Implemented: silc_pkcs_save_[public/private]_key[_data] and
