1 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the IDENTIFY command reply sending to chech better valid
4 clients. It was possible to send incomplete list of replies.
5 Affected file silcd/command.c.
7 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Added silc_client_command[s]_[un]register functions now to
10 dynamically register the commands in client library. Removed
11 the static table of commands. This allows the client library
12 to call commands without causing the application to know about
13 what commands library has called.
15 Removed the INFO command reply kludge to detect when the command
16 was called by library. Now library use its own command reply
17 function for INFO command.
19 Added function silc_client_command_call to call a command.
20 Application can use it to call command, not access the structure
23 Now all commands that are sent by the client library (not
24 explicitly sent by application) use own command reply functions.
26 Affected files around lib/silcclient/ and in
29 * Fixed the WHOIS command reply sending to chech better valid
30 clients. It was possible to send incomplete list of replies.
32 Fixed the WHOIS and IDENTIFY to send the request to router
33 if normal server did not do it and did not find any results.
35 Affected file silcd/command.c.
37 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Moved the internal data from SilcClient context into its
40 own file, not accesible to application. Affected files
41 lib/silcclient/client.h and lib/silcclient/client_internal.h,
42 and other files in client library.
44 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
46 * Added doc/examples installation target in Makefile.am.pre.
49 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
51 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
52 commands the found client entry will be removed from the
53 cache, after notifying application about the error. Affected
54 file lib/silcclient/command_reply.c.
56 * Changed the /MSG to check for exact nickname user gave, and
57 not let `nick' match `nick@host' if it is only one found. Now,
58 user must type the exact nickname (like nick@host2) even if
59 there are no more than one same nicks found. This is to avoid
60 a possibility of sending nickname to wrong nickname since
61 `nick' could match `nick@host'. Affected file is
62 irssi/src/core/silc-servers.c.
64 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
66 * Do not print "you are now server operator" or similar when
67 giving /away command. Affected files are
68 irssi/src/silc/core/client_ops.c, silc-servers.h.
70 * Made the silc_server_command_pending_error_check to send
71 the same command reply payload it received back to the
72 original sender of the command. This way all arguments
73 that was received by the server will be received by the
74 client too. Affected file silcd/command.c.
76 * Added the silc_idcache_add to return the created cache entry
77 to a pointer. Affected file lib/silccore/silcidcache.[ch].
79 * Add global clients to expire if they are not on any channel.
80 This is because normal server will never know if they signoff
81 if they are not on any channel. The cache expiry will take
82 case of these entries. This is done by normal servers only.
83 The affected files are silcd/command_reply.c,
84 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
86 * If server receives invalid ID notification for WHOIS or
87 IDENTIFY and the ID exists in the lists, it is removed.
88 Affected file silcd/command_reply.c.
90 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
91 in client then client entry that it matches is searched and
92 the nickname is printed on the screen for user. Affected
93 file irssi/src/silc/core/client_ops.c.
95 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
97 * Use cache entry expire time in the LIST command reply to
98 purge old entries from the cache after the LIST command
99 reply has been received. This way we don't have non-existent
100 entries in the cache for too long. Affected file is
101 silcd/command_reply.c.
103 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
105 * If we are normal server, and we've not resolved client info
106 in WHOIS or IDENTIFY from router, and it is global client,
107 we'll check whether it is on some channel. If it is not
108 then we cannot be sure about its validity and will resolve it
109 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
110 file silcd/command.c.
112 * Search channel by name (if possible) rather than by ID
113 in IDENTIFY command's command reply. Affected file is
114 silcd/command_reply.c.
116 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
118 * Distribute to the channel passphrase in CMODE_CHANGE notify.
119 Updated specs and implemented it. Affected file silcd/command.c,
120 silcd/packet_send.c and silcd/packet_receive.c.
122 * Implemented the <founder auth> payload handling in the JOIN
123 command. If provided all conditions for channel joining
124 except requirement to provide correct passphrase can be
125 overrided by the channel founder. Updated the protocol specs.
126 Affected file silcd/command.c.
128 Added support for founder auth in JOIN command in client
129 library. Fixed the parsing of the JOIN command now to support
130 all options as they should be. The affected file is
131 lib/silcclient/command.c.
133 * Optimized the WHOIS and IDENTIFY commands to send the request
134 to router only if it includes nicknames or other names. If
135 they include only IDs then check the local cache first before
136 routing. Affected file is silcd/command.c.
138 * Added channels topic announcements. Affected file is
139 silcd/packet_receive.c and silcd/server.c.
141 * Fixed the silc_server_send_notify_topic_set to really destine
142 the packet to channel. Affected file silcd/packet_send.c.
144 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
145 library. Affected file lib/silcclient/client_notify.c.
147 * Added UMODE announcements. Affected file silcd/server.c.
149 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
151 * Memory leak fixes in:
153 lib/silcutil/silcsockconn.c
154 lib/silcske/silcske.c
157 lib/silccrypt/silcpkcs.c
158 lib/silccore/silccommand.c
159 lib/silccore/silcidcache.c
164 * ROBOdoc documented the lib/silcske/groups.h file and a
165 bit changed the interface for better.
167 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
169 * Update the client entry context in the ID cache after
170 nick change. Affected file lib/silcclient/command.c.
171 Fixes the CUMODE command when regaining founder privileges,
172 and a little WHOIS problem.
174 * Fixed silc_net_gethostbyname to correctly call the
175 inet_ntop. Affected file lib/silcutil/silcnet.c.
177 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
179 * Added IPv6 support checking to the configure.in.pre, added
180 also --enable-ipv6 option to override the check. Affected
181 file configure.in.pre.
183 * The silc_thread_create now calls the start function
184 directly if threads support is not compiled in. Removes
185 ugly #ifdef's from generic code. Affected files are
186 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
188 * Added silc_net_gethostby[name/addr]_async to asynchronously
189 resolve. Affected files are lib/silcutil/silcnet.[ch].
191 * Added support for rendering IPv6 based server, client and
192 channel IDs. Affected file lib/silcutil/silcutil.c.
194 * Added support for creating IPv6 based server IDs. Affected
195 file is silcd/serverid.c.
197 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
199 * Added silc_net_gethostby[addr/name] into the
200 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
201 routines. Added silc_net_is_ip[4/6]. Affected file is
202 lib/silcutil/unix/silcunixnet.c. All routines that take
203 address as argument now supports both IPv4 and IPv6 addresses.
205 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
207 * Fixed LIST command reply sending in server. Affected file
210 * Server now sends the kicker's client ID in the KICK notify
211 to the kicked client. Affected file silcd/command.c.
213 * The client library now parses the kickers client ID and
214 UI displays it. Affected files lib/silcclient/client_notify.c
215 and irssi/src/silc/core/silc-channels.c, module-formats.c.
217 * Made all payload parsing function prototypes consistent.
218 They all take now const unsigned char * and uint32 pair as
219 the payload data instead of SilcBuffer. Changes all around
220 the source tree. Other unsigned char* -> const unsigned char*
221 changes around the tree as well.
223 * Optimized SFTP client and server packet sending not to
224 allocate new buffer for each packet but to recycle the
225 first allocated buffer. Affected files are
226 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
228 * Optimized the SFTP client to use SilcList instead of
229 SilcDList for requests, because it is faster. Affected file
230 is lib/silcsftp/sftp_client.c.
232 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
233 into lib/silccore/silcid.[ch].
235 Renamed silcpayload.[ch] into silcargument.[ch].
237 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
239 * If client entry is deleted with active key agreement
240 session, abort the session.
242 The silc_client_abort_key_agreement now calls the completion
243 callback with new SILC_KEY_AGREEMENT_ABORTED status.
245 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
248 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
250 * Don't use __restrict in older GCC's. Affected file is
251 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
253 * silc_net_localhost now attempts to reverse lookup the
254 IP/hostname. Affected file lib/silcutil/silcnet.c.
256 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
257 command. It can be used to gain founder privileges at
258 the same time when joining the channel.
260 Defined that the SILC_NOTIFY_TYPE_KICKED send the
261 kicker's client ID as well. Updated protocol specs.
263 Defined that the server must send SILC_COMMAND_IDENTIFY
264 command reply with error status to client who sent
265 private message with invalid client ID.
267 Updated the protocol specification.
269 * Added silc_server_send_command_reply to send any
270 command reply. Affected file silcd/packet_send.[ch].
272 * Added silc_id_payload_encode_data to encode ID payload
273 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
275 * The server now send IDENTIFY command reply with error
276 status if client ID in private message is invalid. Affected
277 file silcd/packet_receive.c.
279 * Save the server key file with server's IP address in
280 the filename instead of hostname. The affected file is
281 irssi/src/silc/core/client_ops.c.
283 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
285 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
288 * Added libtool support for compiling shared objects in
289 lib/silcsim. Affected file configure.in.pre and
290 lib/silcsim/Makefile.am. Original patch by cras.
292 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
294 * Pid file configuration, and server's config file fixes
295 patch by toma. Updated CREDITS file.
297 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
299 * Fixed silc_client_channel_message to not try to decrypt
300 the message twice if it resolved the destination client
301 information. This could cause of dropping one channel
302 message. Affected file lib/silcclient/client_channel.c.
304 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
306 * Added silc_client_run_one into lib/silcclient/silcapi.h and
307 lib/silcclient/client.c. This function is used when the SILC
308 Client is run under some other scheduler, or event loop or
309 main loop. On GUI applications, for example this may be
310 desired to used to run the client under the GUI application's
311 main loop. Typically the GUI application would register an
312 idle task that calls this function multiple times in a second
313 to quickly process the SILC specific data.
315 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
317 * Fixed silc_server_drop() for dropping the supplementary
318 groups as well, this could cause a security hole on some
321 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
323 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
326 * Write PID file after dropping privileges. Added -F option
327 to run server on foreground. A patch by debolaz.
328 Affected files silcd/server.c, silcd/silcd.c.
330 * Fixed MOTD to return the MOTD file server name. Affected
331 file silcd/command.c.
333 * Added INFO command reply handling to the Irssi SILC Client.
334 Affected file irssi/src/silc/core/client_ops.c.
336 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
338 * Fixed the silc_idcache_list_* routines to really support
339 the dynamic list. Fixes a crash. Affected file is
340 lib/silccore/silcidcache.c.
342 * Fixed the LIST command reply to really call LIST command's
343 pending callbacks. Affected file silcd/command_reply.c.
345 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
347 * Update conn->local_entry->nickname after giving NICK
348 command. Affected file lib/silcclient/command.c.
350 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
352 * Added the [pid] option to the silcd configuration file
354 Affected files: serverconfig.[ch] and silcd.c
356 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Save fingerprint in WHOIS command reply in server.
359 Affected file silcd/command_reply.c.
361 * Fixed NICK commands pending callback registration.
362 Affected file lib/silcclient/command.c.
364 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Use ++server->cmd_ident when sending commands in server,
367 instead of random number. Affected file silcd/command.c.
369 * Fixed GETKEY command reply to call actually GETKEY pending
370 command callbacks. Affected file silcd/command_reply.c.
372 * A bit stricter check for nicknames. Check for same nickname
373 in NICK command also. Affected file silcd/command.c.
375 * Do not call INFO command everytime client ID changes, only
376 during first connecting. Affected file lib/silcclient/client.c.
378 * Set the new nickname only after successful command reply for
379 NICK command is returned by server. Affected file
380 lib/silcclient/command.c.
382 * Remove nicknames from nicklist during server_signoff notify.
383 Should fix /NAMES bit more. The affected file is
384 irssi/src/silc/core/silc-channels.c.
386 * Added `fingerprint' field to the SilcIDListData in the
387 silcd/idlist.h to hold the fingerprint of the client's
390 Send the fingerprint of the client's public key in WHOIS
393 Affected files silcd/command.c, and silcd/idlist.[ch].
395 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
396 create fingerprint from given data.
398 * Show the fingerprint of the client's public key in WHOIS.
399 Affected files irssi/src/module-formats.[ch] and
400 irssi/src/silc/core/client_ops.c.
402 * Format the multiple same nicknames also during JOIN and
403 NICK_CHANGE notifys. Affected file is
404 lib/silcclient/client_notify.c.
406 * Do not print error on screen for invalid private message
407 payload since it can come if someone is sending private
408 messages with wrong key. Affected file
409 lib/silccore/silcprivate.c.
411 * Fixed multiple concurrent /PING crash. Affected file
412 lib/silcclient/command.c.
414 * Changed the wrong ID encoding. All IP addresses must be
415 in MSB first order in encoded format. They were encoded
416 wrong and was in LSB format. Affected files are
417 silcd/serverid.c, lib/silcutil/silcutil.c.
419 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
421 * Call the `connect' client operation through the scheduler
422 in case of error. Affected file lib/silcclient/client.c.
424 * Call the `failure' client operation even if the error
425 occurred locally during a protocol. Affected file is
426 lib/silcclient/protocol.c.
428 * Added support of sending LIST command to router from normal
429 server. This way normal server can get list of all channels
430 in the network too. Fixed the channel list sending in the
431 server too. Affected files are silcd/command.c, and
432 silcd/command_reply.[ch].
434 * Added silc_server_update_channels_by_server and
435 silc_server_remove_channels_by_server. They are used during
436 disconnection of primary router and in backup router protocol.
437 Affected file silcd/server_util.[ch], silcd/server.c and
438 silcd/server_backup.c.
440 * Fixed channel adding to global list in IDENTIFY command
441 reply in server. Affected file silcd/command_reply.c.
443 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
445 * If the incoming packet type is REKEY or REKEY_DONE process
446 that packet always synchronously. Fixes yet another MAC
447 failed error on slow (dialup) connections. Affected file
448 lib/silcclient/client.c and silcd/server.c.
450 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Call check_version SKE callback for initiator too. Affected
453 file lib/silcske/silcske.c.
455 * Implemented fix for security hole found in the SKE that was
456 fixed in the specification few days back; the initiator's
457 public key is now added to the HASH value computation.
458 Added backwards support for the old way of doing it too, for
459 old clients and old servers. Affected file is
460 lib/silcske/silcske.c.
462 * Enabled mutual authentication by default in SKE. If initiator
463 is not providing mutual authentication the responder will
464 force it. This will provide the proof of posession of the
465 private key for responder. The affected files are
466 lib/silcclient/protocol.c and silcd/protocol.c.
468 * Do not cache anymore the server's public key during SKE.
469 We do mutual authentication so the proof of posession of
470 private key is done, and if the server is authenticated in
471 conn auth protocol with public key we must have the public
472 key already. Affected file silcd/protocol.c.
474 * Added new global debug variable: silc_debug_hexdump. If
475 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
476 file lib/silcutil/silclog.[ch].
478 * Fixed compilation warning due to char * -> const char *.
479 Affected files lib/silcutil/silcnet.h, and
480 lib/silccore/silcauth.[ch].
482 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
484 * Fixed CMODE command when new channel key was created. If
485 the creation failed the old key was removed. Next time giving
486 same command would crash the server since the old key was
487 freed already. Affected file silcd/command.c.
489 * Fixed the silc_server_announce_get_channels to not crash
490 on reconnect. Affected file silcd/server.c.
492 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
494 * Added silc_log_set_debug_string function to set a regex
495 string to match for debug output. Only the function names,
496 or filenames matching the given debug string is actually
497 printed. This way it is possible to filter out those debug
498 strings that user is not interested in.
500 Fixed a bug in silc_string_regexify.
502 Affected files lib/silcutil/silclog.[ch], and
503 lib/silcutil/unix/silcunixutil.c.
505 * Changed the -d options in both server and Irssi SILC client
506 to take the debug string as argument. Affected files
507 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
509 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
511 * Added silc_hash_babbleprint to create a Bubble Babble
512 Encoded fingerprint. The encoding is developed by Antti
513 Huima (draft-huima-babble-01.txt), and it creates human
514 readable strings out of binary data. Affected file
515 lib/silccrypt/silchash.[ch].
517 * Print the babble print now in addition of fingerprint as well
518 in Irssi SILC client. Affected files are
519 irssi/src/fe-common/silc/module-formats.[ch],
520 irssi/src/fe-common/silc/core/client_ops.c.
522 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
524 * Fixed a security problem found in SKE. The initiator's
525 public key too is now added to the HASH hash value creation
526 which is signed by the responder to create the SIGN value.
527 This will prevent anyone in the middle to lie to the responder
528 about the initiator's public key. If this is done now, the
529 man in the middle will get caught. Updated the protocol
532 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
534 * Better installation directory handling. Configure module
535 paths and other paths automatically to example_silc* files
536 in doc/. A patch by toma.
538 * Fixed compiler warning from MPI library, and from SILC RNG.
541 * Added SILC_SERVER_PID_FILE to define the pid file for server.
542 It can be configured with ./configure. A patch by toma.
544 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Find correct make to use in prepare-clean. A patch by
547 toma. Affected file prepare-clean.
549 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
551 * Added irssi variables use_auto_addr, auto_bind_ip,
552 auto_bind_port and auto_public_ip.
554 * Changed the interface for silc_client_send_key_agreement
555 in lib/silcclient/silcapi.h
559 irssi/src/silc/core/silc-core.c
561 lib/silcclient/silcapi.h
562 irssi/src/silc/core/silc-channels.c
563 lib/silcclient/client_keyagr.c
566 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Added silc_pkcs_public_key_compare to compare two
569 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
571 * Check that the client who set the founder mode on the
572 channel is the same client that is giving the founder
573 mode to itself. It is done by comparing the saved public
574 key (it is saved even in the authentication is passphrase).
575 Affected file silcd/command.c.
577 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Do not process packet for disconnected socket connection.
580 Affected file lib/silccore/silcpacket.c.
582 * Process the DISCONNECT packet through scheduler in the
583 client library. Affected file lib/silcclient/client.c.
585 * Fixed the silc_client_packet_parse to not to increase
586 the packet sequence number if the conn->sock and the
587 current socket connection is not same. This can happen
588 for example during key agreement when the conn includes
589 multiple socket connections (listeners). Affected file
590 lib/silcclient/client.c.
592 * The sender of the file transfer request now provides also
593 the pointer (listener) for the key exchange protocol. If
594 the listener cannot be created then it sends empty key
595 agreement and lets the receiver provide the listener.
597 Added `local_ip' and `local_port' arguments to the
598 silc_client_file_send. If they are provided they are used,
599 if not then it will attempt to find local IP address, if
600 not found or bind fails then the remote client will provide
603 Affected files are lib/silcclient/client_ftp.c and
604 lib/silcclient/silcapi.h.
606 * Extended the FILE SEND command to support defining the
607 local IP and port for key exchange listener. They are
608 optional. Affected file irssi/src/silc/core/silc-servers.c.

612 * Defined to WHOIS command reply the sending of fingerprint
613 of the client's public key (if the proof of posession of the
614 corresponding private key is verified by the server).
615 Updated to the protocol specification.
617 * Added support of receiving the client's public key's
618 fingerprint in command reply in client library. Affected
619 file is lib/silcclient/command_reply.c, and
620 lib/silcclient/idlist.[ch].

675 client library. Affected file lib/silcclient/client_prvmsg.c.
677 * Do not actually remove the client directly from ID cache
678 during SERVER_SIGNOFF, but invalidate it. This way we
679 preserve the WHOWAS info for the client. Affected file
682 * Fixed SERVER_SIGNOFF notify handling in the server. The
683 server is now able to process incoming SERVER_SIGNOFF notify
684 for a server that it doesn't even know about. It will remove
685 the clients provided in the notify. Affected file
686 silcd/packet_receive.c.
688 * Check for partial packet in data queue after every packet that
689 was found from the queue. Return and wait for more data if
690 there is partial data in queue. Affected file is
691 lib/silccore/silcpacket.c.

710 * Wrote a help file for FILE command.
712 * Added silc_rng_global_get_byte_fast to get not-so-secure
713 random data as fast as possible. Random data is read from
714 /dev/urandom if available and from the SILC RNG if not
715 available. It is used in padding generation. Affected file
716 lib/silccrypt/silcrng.[ch].
718 * All packets in client library are now processed synchronously.
719 Optimized packet processing a lot. Affected file
720 lib/silcclient/client.c.
722 * All server connection packets are processing synchronously
723 now in server, to optimize packet processing. Affected file
726 * Include files are installed now only in Toolkit distribution
727 if make install is given. Affected files: all Makefile.am's.
729 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
731 * Assure that silc_client_notify_by_server_resolve does not
732 resolve the client information multiple times. If it cannot
733 be found by the first it cannot be found at all. Affected
734 file lib/silcclient/client_notify.c.
736 * Fixed WHOWAS command reply calling. Affected file
737 lib/silcclient/command_reply.c.
739 * Removed all references to silc_idlist_get_client from the
740 Irssi SILC client since that call is internal call used by
741 the library. The Irssi SILC client will use now client
742 retrieval functions found in silcapi.h.
744 * Fixed a bug in resolving nickname info before sending
745 private message. It used freed memory. Affected file
746 irssi/src/silc/core/silc-servers.c.
748 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

767 * Added silc_net_localip to return local host's IP address.
768 Affected file lib/silcutil/silcnet.[ch].
770 * If key exchange or rekey protocol is active for a connection
771 parse all packets syncronously since there might be packets
772 in packet queue that we are not able to process without first
773 processing packets before them. Affected file silcd/server,
774 lib/silcclient/client.c.
776 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
777 whether library should continue processing the packet.
778 Affected file lib/silccore/silcpacket.h.

809 lib/silcutil/silcutil.[ch].
811 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Resolve the client info when received private message or
814 channel message for a client which nickname we don't know.
815 Affected files lib/silcclient/client_prvmsg.c and
816 lib/silcclient/client_channel.c.
818 * Do not crash in /KEY if client is not connected. Affected
819 file irssi/src/silc/core/silc-channels.c.
821 * Added SilcClientStatus field to the SilcClientEntry in the
822 lib/silcclient/idlist.h.
824 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
825 is incomplete and is being resolved, it won't be resolved
828 Make sure also that USERS command reply does not resolve
829 twice information. Affected file is
830 lib/silcclient/command_reply.c.
832 Make sure that silc_client_get_clients_by_list does not
833 resolve twice same information.
835 * Check for valid client->id in the silc_server_free_client_data.
836 Affected file silcd/server.c.
838 * Fixed /GETKEY nick@server not to crash if the server entry
839 is not found. Affected file lib/silcclient/command.c.

846 * Better checks for non-printable chars in nick added.
847 Affected file silcd/command.c.
849 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
851 * Call the silc_server_udpate_servers_by_server in the
852 primary router that comes back online in the backup resuming
853 protocol. Otherwise it routes packets wrong. Affected file
854 silcd/server_util.[ch], silcd/server_backup.c.
856 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
859 lib/silcutil/silcbuffmt.[ch].
861 * Redefined the SILC packet header to include the padding
862 length. Affected file lib/silccore/silcpacket.[ch].
864 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
865 length for maximum padding up to 128 bytes). Affected
866 file lib/silccore/silcpacket.h.
868 * Removed all backwards support for old 0.5.x MAC thingies.
869 The SILC packet header change makes it impossible to be
870 backwards compatible.
872 * Send the ENDING packet with timeout in the backup resuming
873 protocol. This is to assure that all routers has connected
874 to the primary router. Affected file silcd/server_backup.c.
876 * Changed the RNG to take the first IV from random data. It
877 used to take it from zero actually. Changed the RNG also
878 to use /dev/urandom during session. /dev/random is used
879 in initialization. Affected file lib/silccrypt/silcrng.[ch].
881 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Changed the SILC packet header to have the first two bytes
884 (the packet length) encrypted. Affected files aroung the
885 code tree, lib/silccore/silcpacket.[ch]. Removed the
886 SilcPacketCheckDecrypt callback. It is not needed anymore
887 since the silc_packet_receive_process will determine now
888 whether the packet is normal or special.
890 * Implemented the unidirectional MAC keys. Affected files
891 lib/silcske/silcske.c, silcd/protocol.c and
892 lib/silcclient/protocol.c.
894 * Implemented the packet sequence number to the MAC computation.
895 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
896 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
897 lib/silcclient/protocol.c.
899 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Allow backup router to announce servers. All servers
902 announced by backup router are added to the global list
903 automatically. Update hte server's socket to our primary
904 router also when backup router announces a server.
905 Affected file silcd/packet_receive.c.
907 * Do not update the client->router in the function
908 silc_server_udpate_clients_by_server if the client is on
909 global list. We might fail to find any specific server
910 for locally connected clients and local cell clients. They
911 should still use the `from' and not `to' as client->router.
912 This fixes backup router resuming protocol. Affected file
915 * Decrease channel statistics count only if the channel
916 deletion worked. Affected files are silcd/server.c and
919 * Added silc_server_update_servers_by_server to update origin
920 of all server entries. Used during backup router protocol.
921 Affected files silcd/server_util.[ch], silcd/server.c. and
922 silcd/backup_router.c.
924 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
925 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
926 silc_hmac_get_hash and silc_hmac_get_name. Affected file
927 lib/silccrypt/silchmac.c.
929 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Assure that router cannot reroute the same channel message
932 to the sender. Affected file silcd/packet_receive.c.
934 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Made better checks that the channel message is not sent
937 to the router it came from. Affected file is
938 silcd/packet_send.c. Fixed memory leak too.
940 * Announce informations for incoming router connection, but
941 only after checking if it is replaced by backup router.
942 Affected file silcd/packet_receive.c.
944 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Fixed the backup resuming protocol to work in multiple
947 router environment. Affected file silcd/server_backup.c.
949 * Route packet only to one router in the function
950 silc_server_packet_send_to_channel. Affected file is
953 * Fixed silc_server_send_notify_dest to set the broadcast
954 flag. Fixed the silc_server_send_notify_topic to actually
955 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
956 Affected file silcd/packet_send.c.
958 * Changed the SFTP Filesystem interface. Changed the
959 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
960 the filesystem operation function. The SilcSFTPFilesystem
961 is now a context that is allocated by all filesystem allocation
962 functions and it already includes the operations structure
963 and filesystem specific context. It is given as argument
964 now to the silc_sftp_server_start. This made the interface
965 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
966 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
968 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
970 * Changed the backup router adding and getting interfaces
971 in the server. The router that will be replaced by the
972 specified backup router is now sent as argument. Affected
973 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
976 * Added silc_net_addr2bin_ne to return the binary form of
977 the IP address in network byte order. Affected files
978 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
980 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Check for existing server ID in silc_server_new_server
983 and in silc_server_connect_to_router_final and remove the
984 old entry if it exists. Affected file silcd/packet_receive.c,
987 * Send the channel message always to only one router, either
988 in upstream or downstream. Affected file is
991 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Wrote the definition of the backup resuming protocol to the
994 protocol specification.
996 * Removed one redundant channel key generation from normal
997 server during joining procedure. Removed one redundant
998 channel key sending from server to router during joining
999 procedure. Affected file silcd/command.c.
1001 * Made minor bugfixes to the backup router resuming protocol.
1002 Affected file silcd/server_backup.c, server.c.
1004 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Added --disable-asm configuration option. Affected files
1007 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1010 * Implemented the backup resuming protocol that is used to
1011 resume the primary router position in the cell after the
1012 primary router comes back online. Affected files
1013 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1014 and silcd/server_util.[ch].
1016 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Sleep two (2) seconds after sending QUIT command to server.
1019 Affected file lib/silcclient/command.c.
1021 * Assure that if outgoing data buffer is pending do not force
1022 send any data. Affected file silcd/packet_send.c.
1024 * Assure that if outgoing data buffer is pending do not force
1025 send any data. Affected file lib/silcclient/client.c.
1027 * Implemented the backup router support when the primary router
1028 goes down. The servers and routers can now use the backup
1029 router as new primary router without loosing connectivity.
1031 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1033 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1034 in the server to indicate disabled entry. All data read
1035 from the connection will be ignored and no data is sent
1036 for entry that is disabled. Affected files are
1037 silcd/idlist.h, silcd/server.c.
1039 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Created SFTP client and server test programs in the
1042 lib/silcsftp/tests directory.
1044 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * Implemented memory filesystem (virtual filesystem) for
1047 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1050 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Implemented the SFTP (SSH File Transfer Protocol) to the
1053 lib/silcsftp. It includes SFTP client and SFTP server
1056 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Moved lib/silccore/silcprotocol.[ch] to the
1059 lib/silcutil library.
1061 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1062 take variable argument list pointer as argument. Affected
1063 file lib/silcutil/silcbuffmt.[ch].
1065 * Added silc_buffer_set function that is used to set data
1066 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1067 Affected file lib/silcutil/silcbuffer.h.
1069 * Changed various routines in the core library to use the new
1070 silc_buffer_set instead of allocating new buffer only for
1073 * Added 64-bit value formatting and unformatting support to the
1074 silc_buffer_[un]format routines. Affected file is
1075 lib/silcutil/silcbuffmt.[ch].
1077 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1078 to includes/bitmove.h.
1080 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Fixed channel user mode saving in client library. Affected
1083 file lib/silcclient/command[_reply].c.
1085 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1087 * Defined the file transfer to the SILC Protocol. Added
1088 new packet type SILC_PACKET_FTP and defined File Transfer
1089 Payload. The mandatory file transfer protocol is SFTP
1090 (SSH File Transfer Protocol). Affected file in addition
1091 of the internet draft is lib/silccore/silcpacket.h.
1093 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1094 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1095 is used as part of backup router protocol when the primary
1096 router of the cell is back online and wishes to resume
1097 the position as primary router.
1099 * Redefined the MAC generation keys in the protocol. The
1100 same key is not used anymore in both direction. Both
1101 direction will now use different keys for sending and
1102 receiving. This fixes a potential security flaw. This
1103 change causes incompatibilities in the protocol.
1105 * Redefined also the MAC computation from the packet.
1106 An packet sequence number is now added to the MAC
1107 computation. This prevents possible replay attacks against
1108 the protocol. This change too causes incompatibilities
1111 Added `sequence' field to the SilcPacketContext to hold
1112 the current sequence number for the packet.

1116 * Added `created' field to the SilcIDListData in the file
1117 silcd/idlist.h to indicate the time when the entry was
1120 * Added `created' field to the SilcChannelEntry too. Affected
1121 file silcd/idlist.h.
1123 * Added `creation_time' aguments to all the announcement functions
1124 in the server. If it is provided then only the entries that
1125 was created after the provided time frame are actually
1126 announced. Affected file silcd/server.[ch].
1128 * The protocol says that the Channel ID's IP address must be
1129 based on the router's IP address. Added check for this in
1130 the silc_server_new_channel when processing incoming New Channel
1131 Payload. Affected file silcd/packet_receive.c.
1133 * Print out the correct version with --version in SILC client.
1134 Affected file irssi/src/silc/core/silc-core.c.
1136 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Fixed WHOWAS command to check for completnes of the client
1139 entry always, not just when the command is coming from client.
1140 Affected file silcd/command.c.
1142 * Added new function silc_server_packet_queue_purge to purge the
1143 outgoing data queue to the network. After the function returns
1144 it is guaranteed that the outgoing packet queue is empty.
1145 Affected file silcd/packet_send.[ch].
1147 * Purge the outgoing packet queue in the rekey protocol's final
1148 callback to assure that all rekey packets go to the network
1149 before quitting the protocol. Affected file silcd/server.c.
1151 * Added silc_client_packet_queue_parse as similar function as
1152 in server to the client library. The affected file is
1153 lib/silcclient/client.c.
1155 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Splitted silcd/server.c and created silcd/server_util.[ch]
1158 for utility functions.
1160 * Added new socket flag SILC_SF_DISABLED to indicate that the
1161 connection is open but nothing can be sent to or received from
1162 the connection. Affected file lib/silcutil/silsockconn.[ch].
1163 The checking for disabled socket is checked in the low level
1164 silc_socket_write and silc_socket_read functions.
1166 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Allow only nicknames and channel names that fits into the
1169 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1171 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * When processing JOIN command reply in server check that if
1174 the channel exists in our global list we'll move it the local
1175 list. Affected file silcd/command_reply.c.
1177 * Fixed the check whether client is joined on the channel already
1178 in JOIN command. Affected file lib/silcclient/command.c.
1180 * Fixed the JOIN command reply to check whether the channel
1181 already exists. Affected file lib/silcclient/command_reply.c.
1183 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Added silc_ske_status_string to map the SKE error numbers
1186 to readable strings. The affected files are
1187 lib/silcske/silcske[_status].[ch].
1189 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Do not show the private channels on the WHOIS channel list
1192 as it is not allowed by the protocol. The affected file is
1195 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Assure that the packet length digged from the actual packet
1198 is something sensible in the silc_packet_decrypt_rest_special
1199 in lib/silccrypt/silcpacket.c.
1201 * Free and NULL the allocated pointer in silc_hmac_alloc if
1202 the HMAC allocation fails. The affected file is
1203 lib/silccrypt/silchmac.c.
1205 * Print the selected security properties to the log files in
1206 the server. Affected file silcd/protocol.c.
1208 * Add SKE's reference counter even if calling the completion
1209 callback manually. Otherwise it goes negative, although it
1210 does not cause any problems. The affected file is
1211 lib/silcske/silcske.c.
1213 * Remove the client entry with short timeout after giving the
1214 KILL command. Affected file lib/silcclient/command.c.
1216 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1217 case all found clients are already disconnected (WHOWAS would
1218 found them) in the server. Affected file silcd/command.c.
1220 * Update the last_receive (time of last data received) to be
1221 updated only when received private or channel message so that
1222 the idle time showed in WHOIS makes more sense.
1224 * Added boolean field `valid' in to the SilcClientEntry in the
1225 client library to indicate whether the entry is valid or not.
1226 This fixes the nickname change bug on channel when changing
1227 the nickname to be same than the old (like nick to Nick) the
1228 nickname formatter doesn't set the new nick anymore to Nick@host.
1229 Affected file lib/silcclient/idlist.[ch].
1231 * Now actually fixed the nickname changing on disconnection.
1232 Added new function silc_change_nick to the Irssi SILC Client.
1233 Affected file irssi/src/silc/core/client_ops.c,
1234 irssi/src/silc/core/silc-nicklist.[ch].
1236 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1238 * Check that the public key exists in the GETKEY command before
1239 trying to encode it. Affected file silcd/command.c.
1241 * Print some notifications on received public keys with GETKEY
1242 command in the Irssi SILC Client. Affected files are
1243 irssi/src/fe-common/silc/module-formats.[ch],
1244 irssi/src/silc/core/client_ops.c.
1246 * Use IDENTIFY command to resolve the server information in the
1247 GETKEY command instead of INFO command. Affected file
1248 lib/silcclient/command.c.
1250 * All command reply functions in the client library now calls
1251 the pending command reply callbacks even if an error has
1252 occurred. The server has done this a long time and now it was
1253 time to move the client library to this as well. Now all
1254 errors can be delivered back to the pending command reply
1255 callbacks if necessary. Affected files are
1256 lib/silcclient/command[_reply].[ch].
1258 * Change the nickname on disconnection back to the username
1259 because in reconnect the server will enforce it to it anyway.
1260 Affected file irssi/src/silc/core/silc-servers.c.
1262 * Fixed a config file parsing bug in the Irssi SILC client.
1263 Affected file irssi/src/silc/core/clientconfig.c.
1265 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * When printing the channel mode on JOIN, verify that the
1268 channel key and channel's HMAC are valid. Affected file
1269 irssi/src/silc/core/client_ops.c.
1271 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1274 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1275 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1277 * Removed channel key rekey task deleting from the function
1278 silc_server_save_channel_key. Affected file silcd/server.c.
1279 Added explicit timeout task context instead that is used to
1280 delete the task if we are registering a new task before the
1281 new task has elapsed.
1283 * When channel key rekey occurs the client library now saves
1284 the old channel key for a short period of time (10 seconds) and
1285 is able to use it in case some is still sending channel
1286 messages encrypted with the old key after the rekey. Affected
1287 file lib/silcclient/[idlist.h|client_channel.c].
1289 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * Added check to the silc_server_new_id_real to not accept
1292 new ID if it is the sender's own ID. Affected file is
1293 silcd/packet_receive.c.
1295 * Assure that we do not announce ourself or the one we've
1296 sending our announcements when we're router and are announcing
1297 servers to our primary router. Affected file silcd/server.c.
1299 * Fixed silc_server_command_identify_check_client to assemble
1300 correct WHOIS packet. It send corrupted WHOIS packet and
1301 caused problem with router to router connections. Affected
1302 file silcd/command.c.
1304 Fixed also silc_server_command_whois_check the same way
1305 as for the IDENTIFY command.
1307 * Added new SilcIDListStatus to the server in the SilcIDListData
1308 structure. The status now includes the current status of
1309 the entry (like registered, resolved etc.). Affected file
1310 silcd/idlist.[ch]. Defined a bunch of different status types
1311 as well. This replaced the old boolean registered field as well.
1313 Added resolve_cmd_ident field to the SilcClientEntry structure
1314 too so that if the entry is for example being resolved so
1315 another command may attach to the same pending command reply
1316 without requiring to resolve the same entry again. This concept
1317 should optimize the WHOIS and the IDENTIFY resolving under
1318 heavy load by taking away unnecessary resolving for entries
1319 that are being resolved already.
1321 Added support for adding multiple pending commands for one
1322 command idenfier. Affected file silcd/command[_reply].[ch].
1324 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1325 before deleting the data. Otherwise the hash table will have
1326 freed data in comparison functions. Affected file is
1327 silcd/command_reply.c.
1329 * Fixed silc_idlist_replace_client_id to add the new entry to
1330 the cache with NULL nickname. Otherwise there will be invalid
1331 memory as the nickname after the nickname is freed. Affected
1332 file silcd/packet_receive.c.
1334 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1335 saved into wrong slots because the previous number of entries
1336 was not taken into account. Affected file silcd/idlist.c.
1337 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1339 * If we are router and we receive JOIN notify to a channel that
1340 does not have any users then notified client is marked as the
1341 channel founder, as it is it. The affected file is
1342 silcd/packet_receive.c
1344 * Added to the extended hash table API's table_del_*ext functions
1345 the destructor as argument too, so that the caller can decide
1346 which destructor to use or whether to use destructor at all.
1347 Affected file lib/silcutil/silchashtable.[ch].
1349 * Fixed ID Cache purging. It actually deleted the entries from
1350 the hash table after the data was freed. The hash table ended
1351 up comparing freed memory. The affected file is
1352 lib/silccore/silcidcache.c.
1354 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Fixed Irssi SILC client's KILL command's HELP syntax.
1358 * The USERS command now resolves the detailed user information
1359 if the userinfo field is missing. Affected file is
1360 lib/silcclient/command_reply.c.
1362 * Do not print error in silc_file_read if the read file does
1363 not exist. Just silently return NULL. Affected file is
1364 lib/silcutil/silcutil.c.
1366 * Fixed the silc_log_output to not wine about NULL filename
1367 and to not create some bogus " " filename. Affected file is
1368 lib/silcutil/silclog.c.
1370 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Fixed various printing bugs on the user interface in the
1373 Irssi SILC Client. Minor changes that were forgotten from
1376 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Fixed the configure.in.pre and the compilation and distribution
1379 environment to support the new autoconf 2.52. That version is
1380 now required to compile the CVS trunk.
1382 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1385 to generally parse user@fqdn format strings. Affected file
1386 lib/silcutil/silcutil.c.
1388 * Added nickname_format and nickname_force_format fields to the
1389 SilcClientParams structure. The first one defines the format
1390 for the nicknames that the library will enforce if the receives
1391 multiple same nicknames. The second one is boolean value and
1392 can be used to force the library to always enforce the format
1393 to the nicknames regardles whether there are multiple nicknames
1394 or not. This configurable formatting was employed to flexibly
1395 support accessing multiple nicknames from the user interface.
1396 The userinterface can now set the nicknames to what ever format
1397 they prefer. Affected file lib/silcclient/silcapi.h.
1399 Added function silc_client_nickname_format to the file
1400 lib/silcclient/idlist.c. It performs the nickname formatting.
1402 Added new field `hostname´ to the SilcClientEntry context.
1403 It holds the hostname of the client. Affected file is
1404 lib/silcclient/idlist.h.
1406 * Irssi SILC Client sets the nicknames in nick@hostn format.
1407 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1408 irssi/src/silc/core/silc-core.c.
1410 The WHOIS printing now also shows both the real nickname and
1411 the formatted nickname so that user knows how to access the
1412 user if there are multiple same nicknames cached. Affected
1413 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1414 printing formatting too to take the hostname now as a separate
1415 argument. The Affected file is
1416 irssi/src/fe-common/silc/modules-formats.[ch].
1418 * Changed the silc_client_get_clients_local to accept the formatted
1419 nickname as argument. It accepts the real nickname too but the
1420 formatted nickname can be used to find the true entry from
1421 multiple entries. Affected file lib/silcclient/silcapi.h and
1422 lib/silcclient/idlist.c.
1424 * Added nickname_format_parse field to the SilcClientParams.
1425 It is a callback function provided by the application to parse
1426 the nickname out of the formatted nickname string. The library
1427 calls it to get the nickname from the formatted string. Since
1428 the application generally knows better the format of the nickname
1429 string it parses it instead of the library, even though library
1430 encodes the formatted string. If the callback function is not
1431 provided then the library will use the string as is. The
1432 affected file is lib/silcclient/silcapi.h.
1434 * All the nickname strings passed to the client library in
1435 commands are now expected to be formatted nickname strings.
1436 If the command does not support the formatted nickname string
1437 it will assume that the sent string is the actual nickname.
1438 Affected file lib/silcclient/command.c.
1440 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Added public key authentication support to OPER and SILCOPER
1443 commands in the client library. Affected file is
1444 lib/silcclient/command.c.
1446 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Changed the get_auth_methdod client operation to be asynchronous.
1449 It can be async if the application resolves the authentication
1450 method from the server during the negotiation. Added new
1451 SilcGetAuthMeth completion callback that the application will
1452 call after resolving the authentication method.
1454 Added function silc_client_request_authentication_method that
1455 the application can use to resolve the authentication method
1456 from the server. Added also SilcConnectionAuthRequest callback
1457 that the library will call after the server has replied. The
1458 application can call this function if it does not know the
1459 current authentication method.
1461 Affected files are lib/silcclient/client.c and
1462 lib/silcclient/silcapi.h.
1464 * The Irssi SILC client now automatically resolves the authentication
1465 method incase any configuration information is not present (and
1466 currently there never is). The affected file is
1467 irssi/src/silc/core/client_ops.c.
1469 * Fixed public key authentication from the client library.
1470 Affected file lib/silcclient/protocol.c. Changed also the
1471 protocol specification about the public key authentication in
1472 the connection authentication protocol. The actual data to be
1473 signed is now computed with a hash function before signing.
1475 * Fixed the public key authentication from the server as well.
1476 Affected file silcd/protocol.c.
1478 * Removed the mlock()'s from the memory allocation routines.
1479 Affected file lib/silcutil/silcmemory.c. The ./configure does
1480 not check anymore for the mlock(). Affected file is
1483 * Fixed USERS command in server to allow the execution of the
1484 command for private and secret channels if the client sending
1485 the command is on the channel. Affected file silcd/command.c.
1487 * Fixed silc_client_get_clients_local to return the clients
1488 count correctly. It could return wrong value. Affected file
1489 lib/silcclient/idlist.c.
1491 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1494 types. The assembler optimizations seemed not to like 64-bit
1495 data types. The assmebler optimizations thus are now enabled
1496 also for BSD systems as opposed to only enable them for Linux.
1498 * Do not check for threads at all on BSD systems. Affected
1499 file configure.in.pre.
1501 * Removed -n and -h options from the Irssi SILC Client since
1502 they are not used in silc.
1504 * Fixed the prime generation to assure that the first digit
1505 of the generated random number is not zero since our conversion
1506 routines does not like number strings that starts with zero
1507 digit. If zero digit is seen the random number is regenerated.
1508 This caused some corrupted RSA keys when the zero first digit
1509 was met. Affected file lib/silcmath/silcprimegen.c.
1511 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Fixed WIN32 configuration in the ./configure script.
1514 Fixed to include xti.h on environments that has it.
1515 Patches by Carsten Ilchmann and andrew.
1517 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Changed the silc_id_create_client_id to be collision
1520 resistant. It is now assured that there cannot be created
1521 two same client ID's. I suspect that some weird bugs in
1522 the server were actually caused by duplicate Client IDs.
1523 Affected file silcd/serverid.[ch]. A router receiving
1524 new ID now also assures and informs the sending server
1525 if the ID caused collision.
1527 * Changed the silc_id_create_channel_id to also assure that
1528 there are no collisions.
1530 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Statement about ignoring the Mutual Authentication flag when
1533 performing rekey with PFS was a bit misleading. It is ignored
1534 if it was set in the initial negotiation, it cannot be even
1535 set in the rekey. Fixed in the ke-auth draft. Started the
1536 new versions of the protocol drafts in the doc/.
1538 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Fixed a bug in silc_client_command_identify_save when saving
1541 new channel information. The channel name was no duplicated
1542 and caused crash on exit. Affected file is
1543 lib/silcclient/command_reply.c.
1545 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Fixed the getkey command handling in the server. Send just
1548 empty OK reply to the sender if the key could not be fetched
1549 (but everything else was ok, like the key just was not available).
1550 Changed the public key parameter to optional in the protocol
1551 specs so that empty OK reply can be sent. Affected file
1554 Added a message to Irssi SILC client to tell to user if the
1555 server did not return a public key.
1557 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Fixed a channel key regeneration bug. It registered new
1560 timeout tasks exponentially until all system resources were
1561 used. Affected file silcd/server.c.
1563 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Added the SILC Document generator to the scripts/silcdoc.
1566 It can be used to generate the Toolkit Reference Manual out
1567 of the source tree. Internally it will also use the RoboDoc
1568 generator now imported in util/robodoc.
1570 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Added couple of return's in rekey protocol if error orccurred
1573 during the protocol. The execution must be terminated.
1574 Affected file silcd/protocol.c. Also, terminate the protocol
1575 always with timeout.
1577 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * The client's Client ID was created initally from the wrong
1580 nickname (it could have been in format nick@host) in the
1581 silc_server_new_client. Affected file silcd/packet_receive.c
1583 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Added some SILC_LOG_ERROR's to various error conditions
1586 if client could not be added to ID cache. Affected files
1587 silcd/packet_receive.c and silcd/server.c.
1589 * When client's sock->user_data is freed, NULL also the
1590 client->router and client->connection pointers. Added check
1591 for these pointers being NULL to various places around the
1592 code. Affected file silcd/server.c.
1594 * Added client->data.registered == TRUE checks to various
1595 places around the code to assure that unregistered client's
1596 are not handled when it is not allowed. Affected file
1599 * Added `bool registered' fields to all
1600 silc_idlist_[server|client]_get_* routines to indicate whether
1601 the fetched client needs to be registered or not. Affected
1602 file silcd/idlist.[ch].
1604 * Add your own entry as registered to the ID cache in the
1605 server. Affected file server.c.
1607 * Fixed a bug in silc_server_new_server. The SilcServer was
1608 set as the new server's context instead of SilcServerEntry.
1609 This naturally caused some weird bugs.
1611 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Do not delete the channel rekey task when adding it
1614 for in silc_server_create_channel_key.
1616 * Changed the silc_server_create_channel_key to return
1617 TRUE or FALSE to indicate the success of the channel key
1620 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Fixed MSVC++ project files and added missing files to
1623 Makefiles under win32/.
1625 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Do not add TCP_NODELAY flag if the operating system
1628 does not have it defined. Affected files are
1629 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1631 * Fixed buffer overflow from Irssi SILC Client. Affected
1632 file irssi/src/fe-common/core/themes.c.
1634 * Fixed double free in client library in the file
1635 lib/silcclient/client.c when disconnecting from server.
1637 * Applied double free patch from cras to Irssi SILC client.
1638 Affected files irssi/src/core/[modules/expandos].c
1640 * Fixed the disconnection handling to Irssi SILC Client.
1641 The application must call silc_client_close_connection
1642 in ops->connect client operation in case of failure of
1643 the connection. Affected file is
1644 irssi/src/silc/core/client_ops.c.
1646 * Do not set sock->protocol to NULL in the function
1647 silc_client_close_connection after executing the protocol's
1648 final callback since the sock might not be valid anymore.
1649 Affected file lib/silcclient/client.c.
1651 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Do not enable SILC_THREADS if the linking with libpthread
1654 did not happen. Affected file configure.in.pre.
1656 * Added notion to protocol specification that server must
1657 verify the sent authentication payload with CMODE when
1658 setting the channel founder key. Implemented it to the
1659 server. Affected file silcd/command.c.
1661 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Added _EXTRA_DIST SILC distribution variable to the
1664 distributions file. It is used to conditionally add extra
1665 files or directories to the specific distribution. Affected
1666 files ./prepare, Makefile.am.pre and distributions.

1671 * Added README.WIN32 for instructions to compile the Toolkit
1674 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Fixed a double free in disconnection in the server. Affected
1677 file is silcd/server.c.
1679 * Fixed the lib/silcske/groups.c to work now also with GMP
1680 MP library. The string conversion did not work when using
1681 specific base and the base is indicated in the string as well.
1683 * Created win32/ directory which now includes MSVC++ specific
1684 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1685 It will appear only in the toolkit distribution
1687 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1689 * Changed the key material distribution function in case when
1690 the hash output is too short. The data is now concatenated
1691 a bit differently than it used to. Made the change to the
1692 SKE protocol specification.
1694 * Added better GMP detection to configure.in.pre. A patch
1697 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Fixed a minor bug in SKE that might cause some problem on
1700 some platforms. Affected file lib/silcske/silcske.c.
1702 * Added the cookie checking for initiator in the SKE. It checks
1703 that the responder returns the sent cookie unmodified. The
1704 affected file is lib/silcske/silcske.c. Added new SKE
1705 error type INVALID_COOKIE that can be sent during the
1706 negotiation. Fixed some memory leaks as well.
1708 * Added the "invalid cookie" error message to Irssi SILC client's
1711 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1713 * Added `task_max' field to the SilcClientParams to indicate
1714 the maximum tasks the scheduler can handle. If set to zero,
1715 default values are used. Affected file lib/silcclient/silcapi.h.
1717 * Fixed memory leaks in silc_client_close_connection. Affected
1718 file lib/silcclient/client.c.
1720 * Added silc_client_del_client_entry to client library to free
1721 all memory of given client entry. Affected file is
1722 lib/silcclient/idlist.[ch].
1724 * Added new functions silc_client_del_channel and
1725 silc_client_del_server to delete channel and server entries.
1726 Affected file lib/silcclient/[silcapi.h/idlist.c].
1728 * Removed silc_client_del_client_by_id from silcapi.h.
1730 * Fixed the INFO command to return the server's own info
1731 correctly when querying by Server ID. Affected file is
1734 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Removed the non-blocking settings in WIN32 code in the
1737 silc_sock_[read/write] and added SleepEx instead. Affected
1738 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1739 of input data is now checked with FIONREAD and ioctlsocket.
1741 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Call silc_schedule_task_del_by_context in the
1744 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1745 Affected file lib/silccore/silcprotocol.c.
1747 * Call silc_protocol_cancel for active protocols in the
1748 silc_server_close_connection if the funtion
1749 silc_server_free_sock_user_data has not been called.
1750 Affected file silcd/server.c.
1752 * Generic tasks cannot be deleted using the del_by_fd
1753 task deleting function since generic tasks does not match
1754 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1756 * Added a notion to SILCOPER help file that the SILCOPER works
1757 only on router server, not on normal server.
1759 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Added for WIN32 support for the new scheduler as well.
1762 Affected file lib/silcutil/win32/silcwin32schedule.c.
1764 * Fixed the SHA1 implementation to work on various platforms.
1766 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1769 API. It is part of the scheduler now. Everything else is
1770 as previously but some functions has changed their names.
1771 Checkout the lib/silcutil/silcschedule.h for the interface.
1772 Updated all applications to use the new interface. Affected
1773 files are lib/silcutil/silcschedule.[ch].
1775 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Found a bug in the SKE implementation. The HASH value,
1778 specified by the protocol, was not computed correctly. The
1779 public key of the responder was not added to the computation
1780 even though it is mandatory. Affected file lib/silcske/silcske.c.
1781 This unfortunately causes incompatibilities with older
1782 clients and servers.
1784 * Added WIN32 specific network init and uninit functions:
1785 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1786 the Winsock2. Affected file lib/silcutil/silcnet.h and
1787 lib/silcutil/win32/silcwin32net.c.
1789 * Set the socket always to nonblocking mode on WIN32 after
1790 reading data or writing data. Affected file is
1791 lib/silcutil/win32/silcwin32sockconn.c.
1793 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Fixed various compilation problems under WIN32. Affected
1796 files lib/silcutil/win32/silcwin32thread.c and
1797 lib/silcutil/win32/silcwin32schedule.c.
1799 * Removed all _internal.h #includes from public header
1800 files. Internal headers must never be included from
1803 Removed also the lib/silcske/payload_internal.h file.
1805 * All include files that may be needed (public and some others
1806 included by the public headers) by application developers are
1807 now copied to the ./includes directory. It does not copy any
1808 internal headers. Affected file Makefile.defines.pre and all
1809 Makefile.am's under lib/ and subdirs.
1811 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Do not change the ~/.silc directory's permissions automatically.
1814 Affected file irssi/src/silc/core/clientutil.c.
1816 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Do not cancel the protocol in silc_server_close_connection
1819 it might cause recursion. Now cancelled in the function
1820 silc_server_free_sock_user_data. Affected file silcd/server.c.
1822 * Fixed the silc_server_remove_clients_by_server to regenerate
1823 the channel keys correctly finally. Added also new function
1824 silc_server_remove_clients_channels to actually do it.
1825 Affected file silcd/server.c.
1827 * Fixed the silc_server_new_channel to not crash by giving
1828 wrong router to the new channel. Affected file is
1829 silcd/packet_receive.c.
1831 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1834 which is given as argument to the silc_client_alloc now.
1835 It can be used to configure the client and set various parameters
1836 that affect the function of the client.
1838 * The USERS command in server did not check whether the channel
1839 is private or secret. Affected file silcd/command.c.
1841 * Added new argument to the USERS command in protocol specification.
1842 The USERS command now can take the channel name as argument
1843 as well. Added support for this in client and server and
1844 updated the protocol specs.
1846 * Completed the GETKEY command in client. It can be now used
1847 to fetch also servers public key not only some clients.
1848 Affected files lib/silcclient/command[_reply].c.
1850 * Added silc_client_get_server to return server entry by the
1851 server name. Affected files lib/silcclient/silcapi.h and
1854 * Redefined the IDENTIFY command in protocol specification to be
1855 more generic. It now can be used to query information about
1856 any entity in the SILC Network, including clients, servers and
1857 channels. The query may be based either the entity's name
1858 or the ID. Added support for this in both client and server.
1860 Affected files silcd/command.c and lib/silcclient/command.c
1861 and command_reply.c.
1863 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1864 the _from_client and _from_server functions. Affected file
1867 * Added silc_client_get_channel_by_id_resolve to the file
1868 lib/silcclient/silcapi.h to resolve channel information by
1869 its ID. Added also silc_client_get_channel_by_id that
1870 does not resolve it from the server.
1872 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Added SilcServerEntry context into the client library
1875 to represent one server. The INFO command now allocates
1876 these to save the resolved server info. For now on the
1877 client library will also keep information about servers,
1878 connected and resolved with INFO.
1880 The INFO command now allocates the SilcServerEntry context
1881 and saves the server info there. The COMMAND_REPLY in
1882 the INFO now returns the parameters to application in
1883 same order as defined in the protocol specification.
1885 The entries are cached in the client->server_cache.
1887 * The INFO command is now issued after received the Client ID
1888 from the server. Affected file lib/silcclient/client.c.
1890 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1891 to the application as the mode changer might be server.
1892 It is guaranteed that NULL is not returned anymore to the
1893 application. Affected file lib/silcclient/client_notify.c.
1895 The ID Type is now also passed to the application so that
1896 it can check whether the returned entry is SilcClientEntry
1899 Added new function silc_client_get_server_by_id to return
1900 the server entry by ID. Affected files are the
1901 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1903 * Do not create the channel in the Irssi SILC Client when issuing
1904 the JOIN command but when received the sucessful JOIN command
1905 reply. Otherwise the channel might get created even though we
1906 could not join it. The Affected file is
1907 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1909 * Fixed a channel joining bug in router. The router must also
1910 check the channel modes, invite and ban lists etc. when serving
1911 the JOIN command sent by normal server. Affected file is
1912 silcd/command.c. The router now resolves the client's
1913 information from the server who sent the JOIN command if it
1914 does not know it, and processes the JOIN command only after
1917 * Changed the SilcCommandCb to take new argument; void *context2.
1918 Affected file lib/silccore/silccommand.h
1920 The second argument in the command callbacks in the server now
1921 includes the SilcServerCommandReplyContext if the command was
1922 called as pending command callback from the command reply.
1923 Otherwise it is NULL. When called as pending the status of the
1924 command reply will be checked and if it was erronous the
1925 error will be sent to the original sender of the command.
1926 This way the client always receives the error messages even
1927 though the server was actually the one who received the error
1928 when it resent the command to router, for example. Affected
1929 files silcd/command[_reply].[ch].
1931 * Fixed sending WHOWAS command's error message to client if
1932 the requested client could not be found. It was missing.
1935 * Changed the CMODE and CUMODE commands reply arguments in the
1936 protocol specification. The Channel ID is now sent in both
1937 of the commands to identify the channel. Implemented this
1938 new feature to the client and server. Affected files
1939 lib/silcclient/command_reply.c and silcd/command.c.
1941 * Made better checks for invite and ban lists in the JOIN
1942 command in server. Affected file silcd/command.c.
1944 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * The server now performs the incoming host IP/DNS lookup
1947 using the silc_socket_host_lookup and thus does not block
1948 the server anymore. Affected file silcd/server.c.
1950 * Completed the multi-thread support for SILC Scheduler in
1951 the lib/silcutil/silcschedule.c.
1953 * Fixed the configure.in.pre to detect the pthread correctly
1956 * Fixed a deadlock in silc_task_queue_wakeup in the file
1957 lib/silcutil/silctask.c.
1959 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Added new function silc_schedule_wakeup that is used in
1962 multi-threaded environment to wakeup the main thread's
1963 schduler. It needs to be used when a thread adds a new task
1964 or removes a task from task queues. After waking up, the
1965 scheduler will detect the task queue changes. If threads
1966 support is not compiled in this function has no effect.
1967 Implemented the wakeup mechanism to both Unix and WIN32
1968 systems. Affected files are lib/silcutil/silcschedule.[ch],
1969 lib/silcutil/unix/silcunixschedule.c and the
1970 lib/silcutil/win32/silcwin32schedule.c.
1972 * Added new function silc_task_queue_wakeup to wakeup the
1973 scheduler by the specified task queue. Affected file
1974 lib/silcutil/silctask.[ch].
1976 * The silc_socket_host_lookup_start now wakes up the scheduler
1977 after adding the timeout task. Affected file is
1978 lib/silcutil/silcsockconn.c.
1980 * The silc_socket_host_lookup is synchronous now if the threads
1981 support is not compiled in. However, the callback is still
1982 called asyncronously through the scheduler, anyway. Affected
1983 file lib/silcutil/silcsockconn.c.
1985 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Added new function silc_socket_host_lookup to perform
1988 asynchronous IP and FQDN lookups for the socket connection.
1989 Affected files lib/silcutil/silcsockconn.[ch].
1991 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1994 that may or may not compile the mutex support in.
1996 Changed the silc_mutex_alloc interface. It allocates the
1997 mutex now to the sent pointer and returns TRUE or FALSE.
1999 Affected file lib/silcutil/silcmutex.h.
2001 * Wrote the SILC Task Queue interface to support multi-threads.
2002 Affected file lib/silcutil/silctask.[ch].
2004 * Wrote the SILC Scheduler to support multi-threads. Affected
2005 file lib/silcutil/silcschedule.c.
2007 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2010 in lib/silcutil/win32/.
2012 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Defined SILC Mutex API and SILC Thread API and implemented
2015 them for Unix. Affected files are
2016 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2017 lib/silcutil/unix/silcunixmutex.c and
2018 lib/silcutil/unix/silcunixthread.c.
2020 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Fixed the silc_server_remove_clients_by_server's channel
2023 key re-generation. The hash table handling was incorrect
2024 and would not work with many channels. Affected file is
2027 * Fixed some memory leaks around the server code.
2029 * Rewrote the silc_server_get_users_on_channel to support IPv6
2030 based Client ID's. Affected file silcd/server.c.
2032 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2033 specification. However, a separate document must be written
2034 to define the detailed signing procedure and the payload
2035 associated with the flag. Defined the flag to the
2036 lib/silccore/silcchannel.h as well.
2038 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Changed the dynamic tables to static size tables in the
2041 lib/silccrypt/silchmac.c.
2043 * Removed GCC dependencies from the code. A patch by cras.
2045 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Do not show the error "Error receiving packet bla bla"
2048 in server if it really was not an error (-2 means that reading
2049 is pending). Affected file silcd/server.c.
2051 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Fixed a possible crash in silc_server_remove_clients_by_server
2054 in silcd/server.c. Fixed there also some memory leaks.
2056 * Fixed the silc_idlist_replace_client_id. It could replace
2057 wrong key in the hash table. Affected file silcd/idlist.c.
2059 * Do not check whether there are global users on the channel
2060 if the channel->global_users is FALSE. Affected functions
2061 silc_server_remove_from_one_channel and
2062 silc_server_remove_from_channels in silcd/server.c. Also,
2063 do not check if the removed client is local as we can be
2064 sure that global client was not removed from the channel
2065 and checking for global users is not needed.
2067 * The silc_server_remove_clients_by_server now re-generates
2068 the channel keys correctly for those channels that had
2069 clients removed from them. Affected file silcd/server.c.
2071 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Found the reason of random crashes in the server. We weren't
2074 ignoring the SIGPIPE signal (which can be sent in write())
2075 and it crashed the server. Affected file silcd/silcd.c.
2077 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Assure that sock->user_data is not NULL in the function
2080 silc_server_packet_send in silcd/packet_send.c.
2082 * Disconnect the remote connection if it could not be added
2083 to any ID lists in the server. The affected file is
2086 * Check in silc_server_packet_send[_real/dest] that the
2087 socket is not disconnecting and ignore the data if it is.
2088 Affected file silcd/packet_send.c.
2090 * Define inline to __inline on native WIN32 compilation.
2091 Affected file includes/silcwin32.h.
2093 * Added some explicit type casts for inline code since MSVC
2094 require them. Affected files lib/silcutil/silcbuffer.h,
2095 lib/trq/silcdlist.h and lib/trq/silclist.h.
2097 * Print warning in log files from now on if the packet
2098 decryption fails. Affected file silcd/server.c.
2100 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Changed the `say' client operation's interface to accept
2103 new `type' argument to indicate the type of the message sent
2104 by the library. The application may filter the library's
2105 messages according the type. The affected file is the
2106 lib/silcclient/silcapi.h.
2108 * Added two new functions to lib/silcclient/silcapi.h:
2109 silc_client_del_client and silc_client_del_client_by_id.
2110 Affected file lib/silcclient/idlist.c.
2112 * Moved the clientincludes.h from includes/ to silc/ and
2113 serverincludes.h from includes/ to silcd/.
2115 * The modes for the CMODE and CUMODE are now passed as
2116 uint32 for application with COMMAND_REPLY. The affected
2117 file is lib/silcclient/command_reply.c.
2119 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2121 * /WHOIS without arguments shows client's own information.
2122 Affected file lib/silcclient/command.c.
2124 * Changed PING to not accept any arguments. The specs
2125 says that client can ping only the connected server so
2126 requiring an argument is not needed. Affected file is
2127 lib/silcclient/command.c.
2129 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Fixed a fatal bug in private message sending and reception
2132 encryption and decryption when using private message keys.
2133 The implementation was incorrect and did not follow the
2134 specification. It causd that some of the message were
2135 lost since it did not use the sending and receiving keys
2136 as the protocol suggests. This has been fixed and will cause
2137 incompatibilities with older clients when sending private
2138 message encrypted with private message keys. Affected files
2139 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2140 and various other in Irssi SILC Client.
2142 Added `responder' boolean argument to the functions
2143 silc_client_add_private_message_key[_ske] to indicate when
2144 the key is added as responder or initiator of the key
2147 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Removed the silc_ske_check_version function and created
2150 a SilcSKECheckVersion callback. Added also a function
2151 silc_ske_set_callbacks that is now used to set all SKE
2152 callbacks. The callback functions are not given to
2153 the SKE functions anymore, but this function is used to
2156 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2158 * Added `silc_version' argument to the silc_client_alloc
2159 to define the version of the application for the library.
2160 The library will use the version string to compare it
2161 against the remote host's (usually a server) version
2162 string. Affected file lib/silcclient/silcapi.h
2164 * Added the KE protocol context to Key Agreement context
2165 in client library so that we can abort the SKE if it
2166 is in process when we get timeout. Affected file is
2167 lib/silcclient/client_keyagr.c.
2169 * Do not resolve the client ID forever if it returns in the
2170 first time that such client does not exist. This was done
2171 for example with private message. Affected file is
2172 lib/silcclient/client_prvmsg.c.
2174 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Do not add regex.h for WIN32. The affected file
2177 includes/silcincludes.h.
2179 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2180 not work yet 100%. It generates the DLL's automatically
2181 when compiling with --with-win32 under cygwin.
2183 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2185 * lib/contrib/regex.c is not compiled on WIN32.
2187 * Added silc_net_get_socket_opt function to the
2188 lib/silcutil/silcnet.h.
2190 * Added includes/silcwin32.h for WIN32 specific includes
2193 * Do not use ptime structure or any of the posix process
2194 functions on WIN32 in lib/silccrypt/silrng.c.
2196 * Added silc_gettimeofday to provide generic function
2197 for struct timeval on all platforms. Added the function
2198 to lib/silcutil/silcutil.h.
2200 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2203 library as they clearly belong there. As a plus side we
2204 can make the actual socket connection routines platform
2207 Added also new generic function silc_socket_read and
2208 silc_socket_write (that used to be silc_packet_[read/write].
2209 The implementation of these are platform specific.
2211 * Added WIN32 specific routines of silc_socket_[read/write]
2212 to lib/silcutil/win32/silcwin32sockconn.c.
2214 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Added preliminary support for native WIN32 compilation under
2217 cygwin (using the -mno-cygwin option for GCC) to the
2218 ./configure.in.pre. The --with-win32 now prepares the
2219 compilation for native WIN32.
2221 * Rewrote the SILC Scheduler interface in the file
2222 lib/silcutil/silcschedule.h. The scheduler is now context
2223 based and does not have anymore any global static scheduler.
2224 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2225 and created lib/silcutil/win32 directory for WIN32 based
2228 * Added Unix specific network routines to the
2229 lib/silcutil/unix/silcunixnet.c and the old
2230 lib/silcutil/silcnet.c includes now only generic routines.
2232 Added WIN32 specific network routines to the
2233 lib/silcutil/win32/silcwin32net.c.
2235 * Added Unix specific utility functions from the
2236 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2238 * Added WIN32 SILC Scheduler to the file
2239 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2242 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Do not handle JOIN notify in the server if the target client
2245 is not registered (idata->registered == FALSE). The affected
2246 file is silcd/packet_receive.c.
2248 * Update the nickrec->founder in event_cumode in the Irssi SILC
2249 client. Affected file irssi/src/silc/core/silc-channels.c.
2251 * Fixed the CUMODE_CHANGE notify handling in the server when
2252 server and router are announcing their clients on channels.
2253 Now the mode changes are saved and notified correctly. The
2254 affected file is /silcd/packet_receive.c.
2256 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2257 They really did not replace the cache entry in the ID Cache.
2258 Now they do that. Affected file silcd/idlist.c.
2260 * Fixed the KICK notify handling in the Irssi SILC client to
2261 update the channel records so that the kicked client does not
2262 appear to be on the channel. The affected file is
2263 irssi/src/silc/core/silc-channels.c.
2265 * Always update the conn->current_channel when executing command
2266 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2268 * Fixed the KILL notify handling in Irssi SILC client to remove
2269 the killed client on all channels.
2271 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Fixed the silc_parse_command_line to remove extra spaces
2274 from the start and end of the arguments. Affected file is
2275 lib/silcutil/silcutil.c.
2277 * Cancel and free any active protocol in the function
2278 silc_server_close_connection. Affected file silcd/server.c.
2280 * Cancel and free any active protocol in the function
2281 silc_client_close_connction. Affected file is
2282 lib/silcclient/client.c.
2284 * Do not execute the KILL command for clients that are in
2285 history (ie. they are not in the network). Affected file is
2288 * Fixed KILL notify handling, client does not crash anymore.
2289 Affected file irssi/src/silc/core/silc-channels.c.
2291 * Reduced the default packet buffer size from 2048 to 1024 in
2292 lib/silccore/silcpacket.c.
2294 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2295 counter to the SKE context that is incresed when the SKE library
2296 performs async operation outside the library. If the outside
2297 process frees the SKE context and FREED status will be set
2298 and the library will detect after the sync operation that the
2299 libary is freed. The affected files are
2300 lib/silcske/silcske[_status].[ch].
2302 * Resolve the client entry information in the function
2303 silc_client_channel_message to assure that NULL pointer is not
2304 passed as client entry to the application. */
2306 * Fixed the task timeout calculation to assure that there is
2307 never negative timeouts. The affected file is
2308 lib/silcutil/silcschedule.c.
2310 * Fixed the channel user mode notification sending in server.
2311 It was sent point-to-point to the router (or to server by router)
2312 but it needs to be destined to a channel. The routines now
2313 supports sending the channel user mode notifys to the channels
2314 when announcing clients and channels. Affected files are
2315 silcd/server.c and silcd/packet_receive.c.
2317 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2318 It did not actually replace the old channel entry in the cache.
2319 Affected file lib/silcclient/client_notify.c.
2321 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Fixed a possible crash in silc_packet_send_prepare. It now
2324 assures always that there is enough space in the buffer and
2325 at the tail area of the buffer (for MAC).
2327 Fixed the inbound buffer reallocation in silc_packet_read.
2328 It was old code and did not handle the reallocation correctly.
2331 The affected file is lib/silccore/silcpacket.c.
2333 * Fixed buffer overflow in silc_parse_nickname in the file
2334 lib/silcutil/silcutil.c.
2336 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * make install generates new server keys only if there is not
2341 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2344 Added check that if the NOREPLY is set then we will not send
2345 the away message. This avoids infinite loop of away messages
2346 if both clients are away. The affected file is
2347 lib/silcclient/client_prvmsg.c.
2349 * Fixed client crash if /NICK was given without arguments.
2350 Affected file lib/silcclient/command.c.
2352 * Server does not send the invite list in INVITE command back
2353 to the client if the list was not altered. Added this notion
2354 to the protocol spec as well. Affected file silcd/command.c.
2356 Fixed possible crash in INVITE command by checking the
2357 value of silc_server_get_client_route command.
2359 * Fixed the INVITE notify type handling. The arguments are now
2360 taken in correct order and client does not crash. The affected
2361 file is irssi/src/silc/core/silc-channels.c.
2363 Removed the "Inviting xxx to channel" message from the
2364 client library away and let the application handle it.
2365 Affected file lib/silcclient/command.c. Added that message
2366 to Irssi SILC client's message formats.
2368 * Fixed CMODE command crash in client. It now checks the
2369 amount of arguments correctly and does not crash. The affected
2370 file is lib/silcclient/command.c.
2372 * Do not create new channel automatically in silc_channels_join
2373 but check whether the channel by that name already exists.
2374 Affected file irssi/silc/core/silc-channels.c.
2376 * Do not send the SERVER_SIGNOFF to router if the disconnected
2377 entity was the router. Affected file silcd/server.c.
2379 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2380 SILC client as it was missing from there.
2382 Added the handling of the KICK notify to the Irssi SILC client
2383 as it was missing. Added "you have been kicked" message to
2384 Irssi SILC client's message modules formats.
2386 Added the handing of the KILL notify to the Irssi SILC client
2387 as it was missing. Added the kill message module formats
2390 The affected file is irssi/src/silc/core/silc-channels.c.
2392 * The router did not save the channel mode the server announced.
2393 Affected file silcd/packet_receive.c.
2395 * Fixed a possible crash in INFO command in server. If the
2396 server did not provide the server info it crashed. Affected
2397 file silcd/command.c.
2399 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Fixed the GETKEY command in the server to check also the
2402 global list. Otherwise the GETKEY would not work correctly
2403 in normal SILC server. Affected file silcd/command.c.
2405 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Fixed GETKEY crash, it crashed if the command did not succseed.
2409 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2412 is now real and not just an macro interface to GMP.
2414 Removed the entire GMP from the source tree and imported new
2415 NSS MPI library instead. Reason for removing GMP is that it is
2416 extremely large and compiles extremely slow. The NSS MPI
2417 is only a few files and compiles in less than 10 seconds.
2418 The speed is also about the same as GMP. The MPI is imported
2419 to lib/silcmath/mpi.
2421 If the system has GMP installed we will still use the GMP.
2422 If it is not then the NSS MPI will be compiled.
2424 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Merged a long nickname (127 characters long) crash bugfix from
2427 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2429 * Merged a freed memory reference bugfix from Irssi CVS tree.
2430 Affected file irssi/src/core/commands.c.
2432 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Added the server's public key sving and verification to the
2435 server when performing the SKE. This was missing and the
2436 remote server's (or router's) public key was accepted without
2437 checking whether we have it previously or trust it at all.
2438 Affected file silcd/protocol.c.
2440 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2442 * Check in the silc_server_timeout_remote if protocol is active
2443 and make sure that the protocol's final callback is called so
2444 that all memory if freed. Affected file silcd/server.c.
2446 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * silc_server_whois_send_reply crashed the server if the nickname
2449 was 127 characters long. Affected file silcd/command.c.
2451 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Added sanity check to the silc_server_new_client. If the hostname
2454 is provided inside username then check that the provided hostname
2455 really is the same as the resolved one. If the hostname was not
2456 resolved then check it from the public key. Affected file is
2457 silcd/packet_receive.c.
2459 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2460 if the server disconnected us and the connection is not valid
2461 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2463 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2464 the library to the lib/silcutil/silcutil.[ch].
2466 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Close log file after open. Affected file
2469 lib/silcutil/silclog.c.
2471 * Check whether sock == NULL in silc_client_send_packet and return
2472 if it is. Affected file lib/silcclient/silcclient.c.
2474 * Check rec->entry == NULL in the Irssi SILC Client before
2475 sending the channel message. Affecte file is
2476 irssi/src/silc/core/silc-servers.c.
2478 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Merged a splitted window bugfix from Irssi CVS tree. The
2481 affected file is irssi/src/fe-text/textbuffer-view.c.
2483 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2484 It did not print nickname.
2486 * Improved the distributions system a bit.
2488 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2491 irssi/src/fe-text/gui-window.c.
2493 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2494 to in-active server. The affected file is
2495 irssi/src/silc/core/client_ops.c.
2497 * Resolve the client in USERS command reply if the entry does
2498 not have username resolved. The affected file is
2499 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2500 command to WHOIS command to really resolve stuff. The USERS
2501 is not used any more in any critical section so WHOIS can
2502 be used even though it might be slower than IDENTIFY.
2504 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2507 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2509 * Changed the protocol API a bit more consistent in the
2510 lib/silccore/silcprotocol.[ch].
2512 * Changed the following headers to ROBODoc format:
2514 lib/silccore/silcpayload.h
2515 lib/silccore/silcprotocol.h
2516 lib/silccore/silcsockconn.h
2518 All core library headers are now formatted.
2520 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2522 * Fixed a bug in Irssi SILC client; do not show that you are
2523 server/router operator if you really are not. Affected file is
2524 irssi/src/silc/core/client_ops.c.
2526 * Renamed silc_command_free_payload to silc_command_payload_free.
2527 Affected file lib/silccore/silccommand.h
2529 * Added silcmath.h to include the prototoypes of various routines
2530 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2533 * Changed the following headers to ROBODoc format:
2535 lib/silccore/silcchannel.h
2536 lib/silccore/silccommand.h
2537 lib/silccore/silcid.h
2538 lib/silccore/silcidcache.h
2539 lib/silccore/silcmode.h
2540 lib/silccore/silcnotify.h
2541 lib/silccore/silcpacket.h
2542 lib/silcmath/silcmath.h
2544 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Added checking to the server code not to start the server if
2547 ciphers and stuff are not configured properly. Affected files
2548 silcd/serverconfig.[h] and silcd/server.c.
2550 * Changed the layout of the header files of the public interfaces
2551 in the SILC libraries. The new layout supports ROBODoc
2552 documentation tool (and some others) so that it is easy to create
2553 a library reference manual. All the other headers and source
2554 code must still follow the CodingStyle document. Also source
2555 code must not include these ROBODoc stuffs, only the headers.
2556 Furthermore, all public interface headers must now be named
2557 by using `silc' prefix, example: silcapi.h, silccipher.h.
2558 Some files were renamed due to this. All the other headers
2559 must not be used as public interfaces. I will update the
2560 CodingStyle document later. Changed following headers, so far:
2562 lib/silcclient/silcapi.h
2563 lib/silccore/silcauth.h
2564 lib/silccore/silcprivate.h
2565 lib/silccrypt/silcdh.h
2567 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * Removed silc_client_packet_send_flush from the client library
2572 as it is not needed. Affected file lib/silcclient/client.[ch].
2574 * Added printing of message of unresolved authentication method
2575 to the Irssi SILC client. Added it to the module formats.
2576 Removed the same message from the client library.
2578 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2580 * Added new distribution feature, DISTLABEL. Every distribution
2581 can define own preprocessor label that can be used in the
2582 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2583 file distributions, acconfig.h.pre and prepare.
2585 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2587 * Added Makefile.defines_int to include the actual definitions
2588 for Makefile.defines.in. Tested the new distribution system,
2589 created distributions and tested installation.
2591 * Added AWAY message printing to the Irssi SILC client. Added
2592 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2594 * Added SCONNECT command to call the SILC's CONNECT command.
2595 Cannot use CONNECT directly since Irssi uses that internally.
2596 Affected file irssi/src/silc/core/silc-servers.c.
2598 Added ACTION local command. It is same as ME command but takes
2599 the channel as mandatory argument.
2601 Rewrote some of the Irssi's help files to suite for SILC
2604 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Added Makefile.defines[.in] that should for now on be included
2607 in all Makefile.am file in the source tree. That file includes
2608 all common compilation definitions for SILC source tree.
2610 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Minor changes to the ./prepare script to change the package
2613 name according the distribution name to the configure.in.
2615 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Created new distribution system. Added file `distributions'
2618 that defines all the distributions that can be created out of
2619 the SILC source tree. The ./prepare script now reads that
2620 file to determine how to prepare the distributions. The
2621 first argument to the ./prepare is the name of the distribution
2622 and second is the version of the distribution. If given
2623 without arguments it creates the default (toolkit) distribution
2624 with the default version (defined in ./prepare).
2626 All Makefile.am files that are subject to the distributions
2627 are now named as Makefile.am.pre. These are ./Makefile.am
2628 and lib/Makefile.am. Others may be changed later.
2630 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2632 * Added invite list, ban list, some key management and connection
2633 error message printing to module formats in the Irssi SILC client.
2635 * Added new silc_client_set_away_message to set the away message
2636 that is back to the person who sent private message. The
2637 affected file lib/silcclient/silcapi.h and the
2638 lib/silcclient/client_prvmsg.c.
2640 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2642 * Fixed the private message sending in the Irssi SILC client,
2643 added local command KEY to the Irssi SILC client.
2645 Added key management and key agreement message formats to the
2646 irssi/src/fe-common/silc/module-formats.[ch].
2648 Added USERS (alias WHO) printing, server/router operator
2649 indication and LIST command printing to the module formats.
2651 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Fixed channel joining notify handling, cumode notify handling
2654 from Irssi SILC client.
2656 * Added SILC specific module-formats to the Irssi SILC client so
2657 that SILC specific message hilighting, colors etc is possible.
2658 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2660 Added channel mode, channel user mode, actions, notices,
2661 whois and whowas printing to the the module-formats.c.
2663 * Fixed a bug in channel deletion in the server. The channel
2664 is not left to the cache even if the channel founder auth mode
2665 is set when there are no users anymore on the channel. Affected
2666 file silcd/server.c.
2668 * The silc_net_localhost now resolves the entire hostname including
2669 the domain name. Affected file lib/silcutil/silcnet.c.
2671 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2673 * Changed the ask_passphrase client operation to be ascynchronous.
2674 It has now a completion callback and a context that the
2675 application must call after it has got the passphrase from
2676 the user. Affected files lib/silcclient/silcapi.h,
2677 lib/silcclient/protocol.c, lib/silcclient/command.c and
2680 Added SilcAskPassphrase callback that the application calls
2681 to deliver the passphrase to the library.
2683 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2684 The public key verification and especially a certificate
2685 verification is asynchronous procedure.
2687 Added new SILC_SKE_STATUS_PENDING status to indicate the
2688 request is pending and a callback will be called to finalize
2691 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2692 indicate that remote end did not send its public key (or
2693 certificate), even though we require it. Added check for this
2694 condition in the SKE. This was a security bug, now fixed.
2696 Defined new SilcSKEVerifyCbCompletion callback that is called
2697 when the verification process is completed.
2699 The affected files lib/silcske/silcske_status.h and
2700 lib/silcske/silcske.[ch].
2702 * Changed the verify_public_key client operation to be async
2703 as well. Defined SilcVerifyPublicKey callback that is used to
2704 indicate the success of the public key verification process.
2706 Changed the server and client to use the new async client
2709 * Changed the Irssi SILC client's internal scheduler to be called
2710 twice as many times as it used to be. As a result the client
2711 should be a bit faster now. Affected file is
2712 irssi/src/silc/core/silc-core.c.
2714 * Added support to Irssi SILC client of asynchronous public key
2715 verification and passphrase inquiry. Affected file is
2716 irssi/src/silc/core/silc-core.c.
2718 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Do not say "You have left channel %s" in client library.
2721 Moved it to the application. Affected files are
2722 lib/silcclient/command.c and silc/client_ops.c.
2724 * Fixed silc_client_get_clients. Command context was not
2725 duplicated and was freed memory in the callback. Affected
2726 file lib/silcclient/idlist.c.
2728 * Do not say "you are now talking..." on JOIN command in the
2729 client library. The appliation must handle it.
2731 * Do not say ".. changed topic to" in command reply in the
2732 client libary. The application must handle it.
2734 * Fixed TOPIC command sending in the client library.
2736 * Fixed a memory leak in silc_client_command_free in the file
2737 lib/silcclient/command.c.
2739 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Imported a modified version of Irssi client to the source tree.
2742 The Irssi will be used to create a new client called
2743 Irssi SILC. Imported to irssi/.
2745 Added silc_core_init_finish function to the Irssi. Affected
2746 file irssi/configure.in.
2748 A lot changes in the Makefile.ams around the irssi tree.
2750 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * Do not rehash if the new size is same as the old size of the
2753 hash table, in the silc_hash_table_rehash*. The affected file
2754 lib/silcutil/silchashtable.c.
2756 * Replaced hash_table_del_by_context calls from the server
2757 (when channel->user_list and client->channels) to the
2758 hash_table_del as it is sufficient and faster.
2760 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Added silc_hash_table_list, silc_hash_table_get and the
2763 SilcHashTableList structure to provide an alternative way to
2764 traverse the hash table. The affected files are
2765 lib/silcutil/silchashtable.[ch].
2767 * Changed the server's idlist routines to use the hash table
2768 routines to optimize the code.
2770 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Replaced the client entry's `channel' list and channel entry's
2773 `user_list' list to hash tables for optimized lookup. Changed
2774 the code to use the hash table interface around the code.
2775 Affected file lib/silcd/idlist.[ch].
2777 * Added `auto_rehash' boolean argument to the function
2778 silc_hash_table_alloc to indicate whether the hash table should
2779 auto-rehash when it thinks is appropriate time. It will
2780 increase the hash table size if the there is twice as much
2781 entries in the table than the size of the table, and will
2782 decrease the size if there are twice as less entries than
2783 the size of the table.
2785 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2789 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * silc_idcache_purge_by_context deletes the entry now by context
2792 as it is supposed to do. Affected file lib/silccore/idcache.c.
2794 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2795 client is not anymore valid (WHOWAS givens the info) and not
2796 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2798 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2800 * Removed the `data' and `data_len' arguments from the ID Cache
2801 interfaces and added `name' argument. ID Cache does not handle
2802 anymore the binary data only a names associated with given ID.
2804 * When hashing a Client ID with silc_hash_id the entire ID is
2805 not hashed anymore, instead only the hash of the Client ID is
2806 hashed. This way we can access the Client ID from the cache
2807 with Client ID but with the hash of the ID (which is a hash of
2808 the nickname) as well without any difference in performance.
2810 Added also silc_idcache_find_by_id_one_ext to do one on one
2811 searching when we have the actual ID. Added also function
2812 silc_hash_client_id_compare. The affected files are
2813 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2815 * When hashing the name associated with a ID it is always done
2816 in lowercase. This way we can access the cache without worrying
2817 about case-sensitivity, even though, for example nicknames are
2820 * Fixed a bug in server with channel message sending. It put
2821 wrong ID type as destination ID. The affected file
2822 silcd/packet_send.c.
2824 * silc_idcache_del_by_context now deletes from all hash tables
2825 by context. Affected file lib/silccore/idcache.c.
2827 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Changed the client library to use the new ID Cache interface.
2830 Changes around the source tree.
2832 * Added silc_hash_table_rehash_ext to rehash with specific
2833 hash function. Affected file lib/silcutil/silchashtable.[ch].
2835 * Added silc_hash_string_compare to compare two strings in the
2836 hash table. Affected file lib/silcutil/silcutil.[ch].
2838 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added new function silc_idcache_del_by_context into the
2841 lib/silccore/idcache.[ch].
2843 * Changed the server's ID list routines to use the new ID Cache
2844 interface. Changes around the source tree.
2846 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Added silc_hash_table_del[_by_context]_ext functions in to the
2849 lib/silcutil/silchashtable.[ch].
2851 Removed silc_hash_table_find_all* routines and added new
2852 silc_hash_table_find_foreach to replace them.
2854 Added silc_hash_table_replace_ext function as extended
2855 replacing function. Separated the simple hash table interface
2856 from the extended hash table interface in the file
2857 lib/silcutil/silchashtable.h.
2859 * Fixed minor bugs and changed it to use some of the new
2860 hash table functions in lib/silccore/idcache.c
2862 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Added new function silc_hash_table_find_all to return all keys
2865 in the hash table by the specified key. As the hash table is
2866 collision resistant it also makes it possible to have several
2867 duplicate keys in the hash table. This function may be used to
2868 find all of the keys from the hash.
2870 Added user_context arguments to the SilcHashFunction,
2871 SilcHashCompare and SilcHashDestructor to deliver user specified
2874 Added new fuctions silc_hash_table_find[_all]_ext to do
2875 extended lookup with specified hash and compare functions and
2876 specified user contexts.
2878 Added new function silc_hash_table_add_ext to add the key
2879 with specified hash function and user context.
2881 Added new function silc_hash_table_foreach to traverse all
2882 entrys in the hash table. Added SilcHashForeach callback
2885 Added new function silc_hash_table_del_by_context to delete
2886 the entry only if the context associated with the key matches.
2888 Affected files are lib/silcutil/silchashtable.[ch].
2890 * Removed silc_hash_[server/client/channel]_id and added just
2891 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2892 silc_hash_id_compare to compare two ID's using as the hash table
2893 comparison function. Added also silc_hash_data to hash
2894 binary data and silc_hash_data_compare to compare it.
2896 * Removed silc_idlist_find_client_by_hash as it is not needed
2897 anymore. Affected file silcd/idlist.[ch].
2899 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2900 to use internally the SilcHashTable. The new ID Cache is a lot
2901 faster than the old one. Some of the ID Cache interface was also
2902 rewritten and obsolete and stupid functions were removed.
2904 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2906 * Added entry_count field to the SilcHashTable to keep the number
2907 of the entries in the table. Implemented the function
2908 silc_hash_table_rehash. Added new function
2909 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2911 Fixed a minor bug in silc_hash_table_free.
2913 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2914 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2915 into the lib/silcutil/silcutil.[ch].
2917 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Implemented a collision resistant hash table into the
2920 lib/silcutil/silchashtable[ch]. See the header and the source
2921 for the SilcHashTable API.
2923 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Merged dotconf version 1.0.2 into lib/dotconf.
2927 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Do not compile anything in lib/silcsim/* if the SIM support
2930 is not enabled. The tree should now compile without problems
2933 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2935 * Compiled the SILC under cygwin. Compiled and tested briefly
2936 without problems. More tests needed. The SIMs didn't compile
2939 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2941 * Fixed possible crash in silc_get_username in the
2942 lib/silcutil/silcutil.c.
2944 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Fixed a va_arg in silc/client_ops.c.
2948 * Oops, RC5 routines were named AES and caused some problems
2949 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2951 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Added new SilcIDIP structure into the lib/silccore/id.h and
2954 replaced the old `ip' fields from all SILC ID's to that type.
2955 This is a step towards IPv6 support.
2957 The silc_id_get_len takes now the ID as an extra argument.
2958 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2959 both IPv4 and IPv6 based ID's.
2961 The affected files are lib/silccore/id.[ch] and other files
2962 around the tree using these routines.
2964 * Removed the ID length arguments in server from various
2965 silc_server_send_notify_* routines -> they are not needed
2968 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Fixed memory leak in silc_encode_pem_file in the file
2971 lib/silcutil/silcutil.c.
2973 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * Check minor version as well in the SKE. Affected files are
2976 silcd/protocol.c and lib/silcclient/protocol.c.
2978 * Added --identifier option to the server so that an identifier
2979 can be when creating the public key for the server. Affected
2980 file is silcd/silcd.c.
2982 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2983 lib/silccrypt/silcpkcs.c.
2985 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Register default ciphers and stuff when using -C option with
2988 the server. Affected file sildc/silcd.c.
2990 * Put back the servers public key filename format, it is better
2991 than the new one. For now, the client keys are saved with the
2992 new filename format. The affected file silc/client_ops.c.
2994 * Implemented the Cipher API for the rest of the ciphers that
2995 did not implement it or implemented it the wrong way.
2997 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Register default ciphers and stuff when using the -S option
3000 in the client. Affected file silc/silc.c. Same also when
3001 creating new key pair with -C option.
3003 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Fixed the silc_verify_public_key client operation function to
3006 save the public keys differently. The fingerprint is now
3007 used as filename and not the hostname. This way also the
3008 client keys are saved uniquely and not with hostnames. The
3009 affected file is silc/client_ops.c.
3011 * Trimmed the silc_hash_fingerprint function to remove extra
3012 whitespaces from the end of the fingerprint. The affected
3013 file is lib/silccrypt/silchash.c.
3017 * Added silc_cipher_register_default function to register all
3018 default ciphers. It can be used when configuration files
3019 does not exist and the application does not want any specific
3020 ciphers in any specific order.
3022 The SilcDList is now used as silc_cipher_list dynamically
3023 allocated cipher list. Removed the static list all together
3024 and now all ciphers must be allocated to the dynamic list.
3025 The silc_cipher_alloc routine was changed to check only the
3028 All silc_cipher_* routines that used to return int returns
3031 The affected files lib/silccrypt/silccrypt.[ch].
3033 * The same thing was done to silc_hash_* as for silc_cipher_*
3034 routines. Affected files lib/silccrypt/silchash.[ch].
3036 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3037 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3038 Added also silc_pkcs_[un]register[_default] functions.
3039 Removed the data_context from the PKCS API.
3041 * Added silc_hmac_register_default function to register default
3042 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3043 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3044 to unregister all hmacs at once.
3046 * Register the default ciphers, hash functions, PKCSs and HMACs
3047 if client's configuration file does not exist. The affected
3050 * The client did not load the hash functions from the SIM
3051 modules at all. Added support for this. Affected file is
3052 silc/clientconfig.c.
3054 * When decoding public key with silc_pkcs_public_key_decode, check
3055 the supported algorithm only if PKCS are registered. Affected
3056 file lib/silccrypt/silcpkcs.c. The same was done with the
3057 silc_pkcs_private_key_decode.
3059 * Fixed the SILC List routines to keep the list always in order.
3060 It used to change the list's order when traversing the list but
3061 not it preserves the order. Affected file lib/trq/silclist.h.
3063 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Added the client library to use the SilcSocketConnection's
3066 reference counter (by silc_socket_dup) to prevent the bug that
3067 the socket object may be freed underneath async operation.
3069 * The name resolv library checking fixes in the configure.in.pre.
3072 * Created new version of the protocol drafts for future
3073 development. The -03 drafts are the ones that will be changed
3074 in the trunk now and the -02 will remain as they are.
3076 * Send list of CUMODE notifys to the router when announcing
3077 the channel users to the router. Affected file silcd/server.c.
3078 If the router receiving channel founder CUMODE for a channel
3079 that already has channel founder it will send CUMODE notify
3080 to the sender to remove the channel founder rights from the
3081 announced client. Affected file silcd/packet_receive.c.
3083 * The CUMODE notify may now use Server ID as well as the entity
3084 who changes the mode. Updated protocool specs.
3086 * Updated INSTALL and README files.
3088 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3090 * New web pages in the http://silc.pspt.fi. The pages was
3095 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Implemented the [DenyConnectin] config section in the server.
3098 Added silc_server_config_denied_conn to check whether incoming
3099 connection is denied. Affected file silcd/serverconfig.[ch].
3101 * Do not check the ports when checking the incoming configuration
3102 data if the port is 0, meaning any. Affected file is
3103 silcd/serverconfig.c.
3105 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Fixed buffer overflow in silc_string_compare in the file
3108 lib/silcutil/silcutil.c.
3110 * Fixed double free in silc_server_command_leave in the file
3113 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Fixed the version checking in the server. Affected file is
3118 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Fixed the configuration data fetching when accepting new
3121 connections in the server. Affected file silcd/server.c.
3123 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * Added `sender_entry' argument to the function
3126 silc_server_packet_relay_to_channel so that we can check
3127 whether some destination actually belongs to the same route
3128 the sender belongs (ie, we must not resend the packet to the
3129 sender). Affected file silcd/packet_send.[ch].
3131 * Added `servername' field to the SilcClientEntry in the server
3132 to hold the name of the server where client is from. Affected
3133 file is silcd/idlist.h.
3135 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Moved the channel message encrypting in the router betwen
3138 router connections from silc_server_channel_message to the
3139 silc_server_packet_relay_to_channel since we want to check
3140 whether we have anybody channel before encrypting anything.
3141 Affected files silcd/packet_[receive/send].c.
3143 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Fixed the [AdminConnection] server config section to support
3146 multiple entries. Affected file silcd/serverconfig.c.
3148 * Added support into the server to check the validity of the
3149 incoming connection before executing any KE or authentication
3152 * The connection configuration is now saved to the KE and
3153 connection auth protocol contexts and not fetched anymore in
3154 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3156 * The local hosts listenning address and port is also resolved
3157 now when starting the server. We want to have the socket object
3158 to include the real address and port for the listener. Added
3159 new function silc_net_check_local_by_sock into the files
3160 lib/silcutil/silcnet.[ch].
3162 * Fixed a broadcast bug in server -> do not broadcast if we
3165 * Fixed a routing bug. Do not route broadcast packets ever.
3166 Broadcast packets must be processed always and not routed since
3167 they may be destined to some other host than yourself and thus
3168 would get routed without no good reason. Affected file is
3171 * Added function silc_server_config_is_primary_route to check
3172 whether primary router connection has been configured (a router
3173 configuration that we are initiating). If there is not, we
3174 will assume that there is only two routers in the SILC network
3175 and we will use the incoming router connection as our primary
3176 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3178 * Changed the order of the broadcasting. Broadcast _after_ the
3179 packet has been processed not before. Affected file is
3182 * Fixed a [ClientConnection] parsing bug. The port was never
3183 parsed correctly thus resulting to port 0. Affected file
3184 silcd/serverconfig.c.
3186 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3187 argument and did not set the broadcast packet flag. Affected
3188 file silcd/packet_send.c. Fixed same bug in the function
3189 silc_server_send_notify as well.
3191 * If we receive NEW_ID packet for our own ID in the server, ignore
3194 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Removed the nickname from the Private Message Payload.
3199 Updated the code and the protocol specs.
3201 * Updated protocol specs for submitting to the IETF.
3203 * Tweaked the Random Number Generator a bit. Affected file
3204 lib/silccrypt/silcrng.c. Exported a new function
3205 silc_rng_[global]_add_noise which can be used to add more
3208 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Do not parse packets with different timeout when protocol
3211 is active -> may cause problem with rekey. Affected file
3214 * When server receives signoff notify it must not create
3215 new channel key if the client is on any channels since the
3216 sender of the signoff notify will create it.
3218 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Added printing of error messages during SKE protocol from the
3221 failure packet sent by server during SKE. Affected file
3224 * Removed the client's failure_callback handling with timeout
3225 and handle it immediately when received.
3227 * The SKE library returned wrong type in SUCCESS and FAILURE
3228 packets. They must be 32 bit MSB not 16 bit MSB.
3230 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Ok, rewrote the logic of the re-key and now it seems to work.
3233 I tested it on high traffic with frequent re-keys without
3234 problems. Added hmac_receive (and renamed hmac to hmac_send)
3235 in SilcClientConnection in lib/silcclient/client.h and
3236 in SilcIDListData in silcd/idlist.h. Also, removed the
3237 SilcPacketParserContext's cipher and hmac fields as they are
3238 not needed anymore and actually caused some problems when
3239 the ciphers and hmac's changed underneath the packet parser.
3241 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3243 * If re-key protocol is active then process the incoming packets
3244 synchronously since we must assure that icoming packets encrypted
3245 with the old key is processed before the new keys is set to
3246 use. This is true other packets than for REKEY packets.
3247 Affected file silcd/server.c. The same was done to client library
3248 as well, affected file lib/silcclient/client.c.
3250 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * Fixed bug in client and server to accept the force send if
3253 the packet is send from silc_[server/client]_packet_process
3254 function. Otherwise the packets are never delivered, oops.
3256 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Disable force sending of packets when REKEY protocol is active.
3259 We must assure that no packet is sent directly when rekey is
3260 performed. All packets must be sent through packet queue.
3261 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3262 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3263 function is silc_[server/client]_packet_send_real to check
3266 * Replaced the SIM paths from example config files to
3267 /usr/local/modules. Also, make install creates now
3268 /usr/local/silc/logs directory to hold all the SILC server
3271 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Made the configure.in.pre work on Solaris. Patch by salo.
3275 * Made all ciphers compatible with non-x86 machines. Defined
3276 CBC mode macros into lib/silccrypt/ciphers_def.h.
3278 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Fixed the make install.
3282 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * When MAC computation fails the silc_packet_decrypt returned 0
3285 even though it was supposed to return -1. Fixed this. The
3286 affected file is lib/silccore/silcpacket.c.
3288 * Do not replace the config files in /etc/silc (in make install)
3289 if they already exist. Affected file ./Makefile.am.
3291 * Do not send re-key packets immediately but through packet queue.
3292 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3294 * Changed silc_net_check_host_by_sock to return FALSE if the
3295 IP/DNS could not be resolved. Though, it returns the IP address
3296 now even if it could not resolve it (but returns also FALSE).
3297 Affected file lib/silcutil/silcnet.[ch].
3299 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Added silc_pkcs_decode_identifier to decode the public key's
3302 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3303 Added also silc_pkcs_free_identifier. Added also new context
3304 SilcPublicKeyIdentifier.
3306 * Added -S option to the silc client. It is used to dump the
3307 contents of the specified public key file.
3309 * Changed the PKCS api to return the public key length when
3310 setting the public key.
3312 * Fixed a fatal bug in the public and private key file loading.
3313 Affected file lib/silccrypt/silcpkcs.c.
3315 * Execute the packet parsing for client with zero (0) timeout
3316 if the protocol is active. Affected file silcd/server.c.
3318 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Made the key generation options to the silcd program. Added
3321 -C option, equivalent to client's option.
3323 * Added new [ServerKeys] config section to the server. It
3324 configures the server's public and private key.
3326 * Defined generic Public Key Payload into the protocol
3327 specification to send specific type of public keys and
3330 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3331 public key or certificate.
3333 * Implemented the GETKEY command to the server and to the
3334 client library and on user interface.
3336 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * Made preliminary `make install' work.
3340 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added SilcServerRekey context into silcd/idlist.h.
3344 * Added the PFS support as defined in the specification to the
3345 SKE protocol. Affected files lib/silcske/*.c.
3347 * Added `ske_group' field to the SilcServerRekey context to hold
3348 the number of the SKE group that is used with PFS in re-key.
3349 Affected file silcd/idlist.h.
3351 * Added PFS re-key support to the server. Affected file is
3354 * Added silc_protocol_cancel to cancel execution of the next
3355 state of the protocol. Affected file is
3356 lib/silccore/silcprotocol.[ch].
3358 * Added the re-key support with and without PFS to the client
3359 library. Re-key is performed once in an hour, by default.
3361 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3362 Added silc_client_rekey_callback and silc_client_rekey_final.
3363 Affected files are lib/silcclient/protocol.[ch] and
3364 lib/silcclient/client.[ch].
3366 * Removed the `hmac_key' and `hmac_key_len' fields from the
3367 SilcClientConnection structure; not needed. Affected file is
3368 lib/silcclient/client.h.
3372 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3374 * Do not ask whether user wants to use the negotiated private key
3375 for private messages, just use it. Affected file is
3376 silc/local_command.c.
3378 * Added `send_enc_key' and `enc_key_len' fields to the
3379 SilcIDListData structure since they are needed in the re-key
3380 phase. Affected file is silcd/idlist.[ch].
3382 * Implemented the simple re-key protocol into the server.
3383 Affected files silcd/server.c and silcd/protocol.[ch]. The
3384 re-key will be performed once in an hour, by default.
3386 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3387 Added silc_server_rekey, silc_server_rekey_callback and
3388 silc_server_rekey_final.
3390 * Removed Tunneled flag from the protocol. Updated the code
3391 and the specifications.
3393 * Adde `pfs' field to the SilcIDListData to indicate whether
3394 the PFS is to be performed in the re-key. Affected file is
3397 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3400 int64 of at least the xintXX size. If void * is less that 4
3401 bytes uint32 * will be used. Defined bool as boolean.
3403 * Changed _ALL_ unsigned long and unsigned int to uint32,
3404 unsgined short to uint16 in the source tree.
3406 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3407 not handle clients that has entry->data.registered == FALSE.
3408 They are not in the network anymore. Affected file is
3411 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Implemented the sending of the SERVER_SIGNOFF notify in the
3414 server. Affected file is silcd/server.c.
3416 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3417 Added also silc_notify_payload_encode_args into the
3418 lib/silccore/silcnotify.[ch].
3420 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3421 Affected file silcd/packet_receive.c.
3423 * Implemented the SERVER_SIGNOFF notify handling in the client
3424 library. Affected file lib/silcclient/client_notify.c. Also,
3425 implemnted the printing of the SERVER_SIGNOFF info to the
3426 application. Affected file silc/client_ops.c.
3428 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3429 if the deleting was successful. Affected file silcd/idlist.[ch].
3431 * Added support for public key authentication in the connection
3432 authentication protocol in the client library. Affected file
3433 lib/silcclient/protocol.c.
3435 * Changed the server's silc_idlist_get_clients_by_* interface
3436 to support already allocated array so that new entries may be
3437 added to pre-allocated array. Affected file silcd/idlist.[ch].
3438 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3439 and command replies.
3441 * All command reply functions in the server now calls the
3442 pending command callback even if error occured. This way the
3443 error will be delivered to the client as well. Affected files
3444 silcd/command.c and silcd/command_reply.c.
3446 * Fixed INFO command to return local server's info if no server
3447 was provided. Affected file lib/silcclient/command.c.
3449 * Removed RESTART command for good. Updated the code and the
3452 * Rewrote parts of the task system. It is a bit simpler now.
3453 Removed unsued task priorities. The affected files are
3454 lib/silcutil/silctask.[ch].
3456 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Moved the USERS printing from the library to the application.
3459 Affected files lib/silcclient/command.c and silc/client_ops.c.
3461 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Added channel key re-key support. The re-key is perfomed
3466 only by the router and is done once in an hour. Added `rekey'
3467 field to the SilcChannelEntry in the server. Affected files
3468 silcd/server.c and silcd/idlist.h.
3470 * Added silc_task_unregister_by_context into the file
3471 lib/silcutil/silctask.[ch].
3473 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Added SILC_UMODE_GONE mode to indicate when the client is not
3476 present in the SILC network. Added also support to the local
3477 command AWAY that will set this mode. Added support of showing
3478 "xxx is gone" in WHOIS command. The USERS command shows the
3479 gone status as well.
3481 * Fixed setting server and router operator privileges in the
3482 server's UMODE command. Affected file silcd/command.c.
3484 * Merged the SKE KE1 and KE2 payloads into one payload. The
3485 new KE payload is equivalent to the old KE2 payload.
3487 Cleaned up the SKE Start Payload parsing. It now uses the
3488 simple buffer unformatting to do the parsing. A lot faster
3491 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3492 to the SKE that is used to indicate whether both of the SKE
3493 parties should perform authentication. By default only the
3494 responder performs authentication. By setting this flag also
3495 the initiator must do authentication. By default it is unset
3496 since in normal SKE case, client to server connection, only
3497 the responder should do authentication. When doing SKE between
3498 two clients both should perform authentication. Updated the
3499 code and the protocol specs.
3501 * A little fix to IDENTIFY command in the server. Search the
3502 client first by hash not nickname. Affected file is
3505 * Fixed the silc_client_close_connection to support closing
3506 the client to client connections wihtout deleting too much
3507 data. Affected file lib/silcclient/client.c.
3509 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3510 are received if protocol used to be active but is not anymore
3511 the application would crash due to NULL pointer dereference.
3512 Affected files silcd/server.c and lib/silcclient/client.c.
3514 * Added `hash' field to the SilcClientConnection to include
3515 the hash function negotiated in the SKE protocol.
3517 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3518 to set the channel founder authentication data. A client can
3519 claim the founder rights later by providing the authentication
3520 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3521 This way the channel founder can regain the channel founder
3522 privileges even it is left the channel. This works only on
3523 local server and the client must be connected to the same
3524 server to be able to regain the founder rights. Updated the
3525 protocol specs accordingly.
3527 Added support to the CMODE command in the client to set the
3528 founder auth data. Read the README to see how to set it.
3530 Added support to the CUMODE command to claim the founder
3531 rights. Read the README to see how to do it.
3533 Added support for the founder authentication to the Channel
3534 Entry in the server. Affected file silcd/idlist.h.
3536 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3537 server's CMODE command. Affected file silcd/command.c.
3539 * Added the following new functions into lib/silccore/silcauth.[ch]:
3540 silc_auth_get_method and silc_auth_get_data.
3542 * The server now saves the remote hosts public key to the
3543 SilcIDListData pointer. Affected file silcd/protocol.c.
3545 * The normal server now does not remove the channel entry from
3546 the cache if the founder authentication data is set. It used
3547 to remove it if the founder was the last one on the channel on
3548 the server and left the channel. The auth data is saved and
3549 if the channel is re-joined later the old entry is used with
3550 the old auth data. Affected files silcd/command_reply.c and
3553 * Removed the `pkcs' field from the SilcIDListData structure
3554 in the server; it is not used. Affected file silcd/idlist.h.
3556 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Fixed packet processing on slow links. Partial packets were
3559 never re-processed because the incoming data buffer was cleared
3560 by the application. Application must not directly clear the
3561 sock->inbuf, the packet processing routines handle it. Fixed
3562 this in client library and in server.
3564 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Fixed the WHOIS and IDENTIFY send reply function to really
3567 check whether to send list or just one entry. Affected file
3570 * Cleaned up the LEAVE command's channel key distribution. The
3571 affected file silcd/command.c.
3573 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3574 can enforce the channel mode as well. In that case the ID
3575 includes the ID of the server. The code now enforces the
3576 mode change if the router have different mode than the server.
3578 * The notify client operation with CMODE_CHANGE notify can now
3579 return NULL client_entry pointer if the CMODE was not changed
3580 by client. Application must check for this.
3582 * Added <Server ID> argument to INFO command to support server
3583 info fetching by Server ID.
3585 * Added silc_server_announce_get_channel_users to get assembled
3586 packets of channel users of the specified channel. Affected
3587 file silcd/server.[ch].
3589 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3590 was freed underneath the ID Cache.
3592 * Re-announce clients when the server received CHANNEL_CHANGE
3593 notify from the router. Affected file silcd/packet_send.c.
3595 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3598 crashed since it did not handle the fact that there is no cipher
3599 called "3" and didn't check the error condition. Now fixed.
3601 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3602 flag. It can be used to send message requests.
3604 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Implemented the RESTART command in the client.
3608 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3609 notice type messages. Added notice printing to the user
3612 * The channel keys are not re-generated if the channel's mode
3613 is PRIVKEY, ie private key on the channel exists. Affected
3614 files silcd/server.c and silcd/command.c.
3616 * Fixed a little bug in channel message delivery when channel
3617 private keys are set in the server. Affected file is
3618 silcd/packet_send.c.
3620 * Changed the setting on channel->on_channel = TRUE from the
3621 silc_client_save_channel_key to the JOIN command reply. The
3622 key payload is not received if the private channel key is set.
3623 Affected file lib/silcclient/command_reply.c and the
3624 lib/silcclient/client_channel.c.
3626 * When the CMODE_CHANGE notify is sent and the channel private
3627 key mode is removed the channel key must be re-generated in
3628 other cells as well. Added this support for the router in the
3629 silcd/packet_receive.c.
3631 * Added new local command NOTICE to send notice message on
3632 channel. Affected file silc/local_command.[ch].
3634 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Added new local command ME to the client. It is used to send
3637 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3638 some action. Affected file silc/local_command.[ch].
3640 * Changed channel_message and private_message client operations
3641 to deliver the message flags to the application. Added also
3642 the `flags' arguments to the silc_client_send_channel_message
3643 and silc_client_send_private_message functions. Affected file
3646 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Redefined the Private Message Payload to support private message
3649 keys and to support the new private message flags. Updated
3650 the protocol specs. Flags makes it possible to have for example
3651 CTCP style messages.
3653 * Added new type SilcPrivateMessagePayload and defined an API
3654 for it in the lib/silcclient/silcprivate.[ch].
3656 * Tested private message private keys successfully. Tested the
3657 private message key set, unset and list commands with the new
3660 * Redefined the Channel Message Payload to include the channel
3661 message flags (equal with private message flags) to support
3662 for example CTCP style messages.
3664 * Defined some of the message (for channel and private message)
3665 flags. Updated the protocol specs and added the flags to the
3666 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3668 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Added SilcKeyAgreementStatus type to the key agreement routines
3671 to indicate the current status and error if one occured.
3672 The status types are defined in the lib/silcclient/silcapi.h.
3674 * Added new local command KEY that is used to set and unset private
3675 keys for channels, set and unset private keys for private messages
3676 with remote clients and to send key agreement requests and
3677 negotiate the key agreement protocol with remote client. The
3678 key agreement is supported only to negotiate private message keys,
3679 it currently cannot be used to negotiate private keys for channels,
3680 as it is not convenient for that purpose.
3682 * Fixed a minor pending callback setting bug in the function
3683 silc_client_get_client_by_id_resolve, now the function works.
3684 Affected file lib/silcclient/idlist.c.
3686 * Added function silc_net_get_local_port to get local bound
3687 port by socket. Added to lib/silcutil/silcnet.[ch].
3689 * Added `sockets' and `sockets_count' fields to the SilcClient
3690 object. They hold the sockets of the listenning sockets in
3691 the client. Listenning sockets may be for example the key
3692 agreement server. Affected file lib/silcclient/client.[ch].
3693 Added functions the silc_client_add_socket and the
3694 silc_client_del_socket. They are exported to the application
3697 * Added ~./silc/clientkeys to support other client's public keys.
3699 * Renamed verify_server_key client operation to verify_public_key
3700 and added one argument to indicate the type of the connection
3701 (server, client etc.).
3703 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Added silc_server_connection_auth_request to handle the
3706 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3707 silcd/packet_receive.[ch].
3709 * Added silc_server_send_connection_auth_request into the
3710 silcd/packet_send.c to send the connection auth request packet.
3712 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3715 * Fixed the public key authentication in responder side in the
3716 server. The `auth_data' pointer includes the SilcPublicKey
3717 not the path to the public key. Affected file silcd/protocol.c.
3719 * Implemented the public key authentication in the initiator side
3720 in the server. Affected file silcd/protocol.c.
3722 * Removed the [RedirectClient] config section from the server
3723 configuration. Is not needed and I don't want to implement it.
3725 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Cleaned up the CMODE command in the server. It now works
3728 correctly and supports all the modes defined in the protocol.
3729 Affected file is silcd/command.c.
3731 * Added `hmac_name' field to the SilcChannelEntry in the server
3732 to hold the default HMAC of the channel. It can be set when
3733 creating the channel (with JOIN command). Affected files
3736 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3737 type to indicate the change of the current cipher and hmac
3738 on the channel. Client can safely ignore the <cipher> argument
3739 (if it chooses to do so) since the CHANNEL_KEY packet will
3740 force the channel key change anyway. The <hmac> argument is
3741 important since the client is responsible of setting the new
3742 HMAC and the hmac key into use.
3744 * Fixed the CMODE command in the client library as well.
3746 * Tested CMODE command in router environment successfully.
3748 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Show the version of the remote client (or server) when connecting
3751 to the server. It is logged to the log file. Affected file
3752 is silcd/protocol.c.
3754 * Fixed the KILLED notify handling in the client library. The
3755 client must be removed from all channels when receiving the
3758 Also, do not remove the client entry when giving the KILL
3759 command but when the KILLED notify is received.
3761 * Removed silc_idlist_find_client_by_nickname from the server.
3762 Not needed anymore. Affected files silcd/idlist.[ch].
3764 * Implemented the CHANNEL_CHANGE notify type handling to the
3765 server. Affected file silcd/server.c.
3769 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3783 * Added function silc_server_get_client_resolve to find the
3784 client entry by ID from all ID lists and then resolve it
3785 (using WHOIS) if it cannot be found. Affected file is
3788 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Implemented the BAN command to the client library.
3792 * The JOIN command in the server now checks the invite list
3795 * Changed the silc_command_reply_payload_encode_va and the
3796 silc_command_payload_encode_va to support that if argument is
3797 NULL it ignores and checks the next argument. Affected file
3798 lib/silccore/silccommand.c.
3800 * Added silc_server_send_notify_ban to send the BAN notify
3801 type between routers.
3803 * Chaned the silc_notify_payload_encode to support that if
3804 argument is NULL it ignores and checks the next argument.
3805 Affected file lib/silccore/silcnotify.c.
3807 * Tested ban lists in router environment successfully.
3809 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Implemented BAN command to the server, in silcd/command.[ch].
3813 * Removed the BAN and INVITE_LIST modes from the CMODE command
3816 * Added function silc_string_match to regex match two strings.
3817 Affected files lib/silcutil/silcutil.[ch].
3819 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Redefined parts of the SilcChannelEntry in the server to support
3822 the new ban and invite lists.
3824 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Redefined the INVITE command. The same command can be used to
3827 invite individuals to the channel but also to manage the invite
3828 list of the channel (to add to and remove from the invite list).
3829 Updated the protocol specs.
3831 * Added new command SILC_COMMAND_BAN that can be used to manage
3832 the ban list of the channel. Updated the protocol specs.
3834 * Removed the channel modes: the SILC_CMODE_BAN and the
3835 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3836 in the CMODE command. The equivalent features are now available
3837 using INVITE and BAN commands. Updated the protocol specs.
3839 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3840 in the network about change in the current ban list. The notify
3841 type is not used by the client.
3843 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3844 support the invite lists.
3846 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Added new function silc_string_regexify that converts string
3849 including wildcard characters into regex string that can
3850 be used by the GNU regex library. Added into the file
3851 lib/silcutil/silcutil.[ch].
3853 Added silc_string_regex_combine to combine to regex strings
3854 into one so that they can be used as one regex string by
3855 the GNU regex library. Added into the file
3856 lib/silcutil/silcutil.[ch].
3858 Added silc_string_regex_match to match two strings. It returns
3859 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3861 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Imported GNU regex to the soruce tree into lib/contrib.
3864 Fixed some compiler warning from the regex.c.
3866 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Fixed MOTD command in the server to work in router environment.
3870 * Fixed the MOTD command in the client library to support
3871 the server argument in the command.
3873 * Added `nickname_len' argument to the silc_idlist_add_client
3874 in the server, as the `nickname' argument may be binary data
3877 * Added silc_idlist_get_channels to return all channels from
3880 * Implemented LIST command to the server. Affected file is
3883 * Implemented the LIST command to the client library and on the
3886 * Added [<user count>] argument to the LIST command reply.
3887 With private channels the user count is not shown.
3889 * Updated TODO and README.
3891 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * The client entry's data.registered must be TRUE even with
3894 global client entry on global client list. The data.registered
3895 is used to check whether the client is anymore in the network,
3896 for example with WHOWAS command so it must be valid.
3898 * Fixed the WHOWAS command in the server. It now actually works
3899 in router environment. Added function into silcd/command_reply.c
3900 silc_server_command_reply_whowas_save.
3902 * Added silc_idlist_purge function to the silcd/idlist.c
3903 to periodically purge the ID Cache.
3905 * Fixed INFO command in the server. It works now in router
3906 environment. Added <server name> argument to the INFO command
3907 reply. Updated the protocol specs.
3909 * Fixed minor bug in silc_idcache_purge to not purge if the
3910 expire value is zero.
3912 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3913 they were buggy because of the WHOWAS information.
3915 * Fixed local command MSG to handle the async resolving of
3916 the remote client properly. It used to fail the first MSG.
3917 Affected file silc/local_command.c.
3919 * Added `data_len' field to SilcIDCache context.
3921 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3923 * Update TODO. Todo in commands in the server.
3925 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3928 used by routers as broadcast packet to inform other routers
3929 about the changed user mode.
3931 Implemented the notify handling in the server. Affected file is
3932 silcd/packet_receive.c. Added the function
3933 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3935 * Added new generic Channel Payload and deprecated the New Channel
3936 Payload. The New Channel Payload is now the generic Channel
3939 * Added new argument `mode' to the silc_server_send_new_channel
3940 as it is required in the Channel Payload now.
3942 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3943 and created a new and real SilChannelPayload to represent the
3944 new generic Channel Payload. Implemented the encode/decode
3945 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3947 * Added silc_server_get_client_channel_list to return the list
3948 of channels the client has joined for WHOIS command reply.
3949 Affected file silcd/server.[ch].
3951 * Implemented the channel list sending in the WHOIS command reply
3952 in server and in the client.
3954 Implemented the channel list displaying on the user interface
3955 as well. Affected file silc/client_ops.c.
3957 * Added silc_channel_payload_parse_list to parse list of Channel
3958 Payloads. It returns SilcDList list of SilcChannelPayloads.
3959 Client for example can use this function to parse the list of
3960 channels it receives in the WHOIS command reply. The caller
3961 must free the list by calling silc_channel_payload_list_free.
3962 Affected files lib/silccore/silcchannel.[ch].
3964 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Added one new argument <user mode> to the WHOIS command reply
3967 to return the mode of the user in SILC. Updated the protocol
3970 Implemented it to the server and client.
3972 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Fixed the mode printing on the user interface on joining.
3975 Affected file silc/client_ops.c.
3977 * Implemented the UMODE command and user modes in general to the
3978 client library and to the user interface.
3980 * Implemented the UMODE command to the server.
3982 * The server now sends UNKNOWN_COMMAND error status if client sends
3983 unknown command. Affected file silcd/command.c.
3985 * All server commands now handle the command identifier the right
3986 way when sending the command reply to the client. The client can
3987 use to identify the command replies with the identifier.
3989 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Added silc_server_get_client_route to resolve the route to
3992 the client indicated by the client ID. Affected file is
3995 * Added silc_server_relay_packet as general function to relay
3996 packet to arbitrary destination. This deprecates functions
3997 like _send_private_message_key, _relay_notify etc. Affected
3998 file is silcd/packet_send.[ch].
4000 Removed silc_server_send_key_agreement,
4001 silc_server_send_private_message_key and
4002 silc_server_packet_relay_notify functions from the file
4003 silcd/packet_send.[ch].
4007 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4008 server. Affected file silcd/packet_receive.[ch].
4010 * Implemented the KILL command to the client. Implemented the
4011 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4012 Affected files lib/silcclient/command[_reply].c and
4013 lib/silcclient/client_notify.c. Implemented the KILL notify
4014 printing in the user inteface.
4016 * Fixed a lot silc_parse_nick memory leaks from the client
4017 library in the file lib/silcclient/command.c.
4019 * Changed the silc_server_send_notify_on_channels's `sender'
4020 argument from SilcSocketConnection to SilcClientEntry to
4021 check the sender as entry and not as connection object and not
4022 to send to the client provided as argument. The affected file
4023 is silcd/packet_send.[ch].
4025 * The notify packets that are destined directly to the client used
4026 to not to be processed by the server. Now changed that and the
4027 server processes all notify packets. After relaying the packet
4028 to the client the notify packet is processed in the server.
4030 * The silc_server_free_client_data now checks whether there is
4031 pending outgoing traffic for the client and purges the data to
4032 the network before removing the client entry.
4034 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4037 an client is killed from the SILC Network. Updated the protocol
4040 Added new function silc_server_send_notify_killed to the
4041 silcd/packet_send.[ch].
4043 * Added function silc_server_packet_relay_notify to relay notify
4044 packets that are destined directly to a client. In this case
4045 the server does not process the notify packets but merely relays
4046 it to the client. Affected file silcd/packet_send.[ch].
4048 Added also silc_server_packet_process_relay_notify to check
4049 whereto relay the notify. Affected file is
4050 silcd/packet_receive.[ch].
4052 * Implemented the KILL command to the server.
4056 * Added the backup schema desgined last fall to the protocol
4057 specs for everyone to see. The specification is in the
4058 *-spec-xx.txt draft and the packet type definitions for the
4059 backup routers is in *-pp-xx.txt draft. Thusly, added also
4060 new packet type SILC_PACKET_CELL_ROUTERS.
4062 * A big security problem in the implementation discovered. The
4063 signoff of an client did not cause new channel key generation
4064 which it of course should've done. The channel keys must be
4065 always re-generated when client leaves (or signoffs) the channel.
4066 The silc_server_remove_from_channels funtion now handles
4067 the channel key re-generation.
4069 * Added `sender' argument to the silc_server_send_notify_on_channels
4070 to not to send the client provided as argument. Affected file
4071 silcd/packet_send.[ch].
4073 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Implemented OPER and SILCOPER commands into the server and
4078 * Added silc_auth_verify and silc_auth_verify_data to verify
4079 the authentication directly from the authentication payload.
4080 It supports verifying both passphrase and public key based
4081 authentication. Affected file lib/silccore/silcauth.[ch].
4083 * Added `hash' field to the SilcIDListData structure. It is the
4084 hash negotiated in the SKE protocol. Affected file is
4087 * Slight redesigning of the SilcAuthPayload handling routines.
4088 Do not send SilcPKCS but SilcPublicKey as argument.
4090 * Implemented the public key authentication support to the
4091 serverconfig. The public key is loaded from the provided path
4092 and saved as authentication data to void * pointer. Thus,
4093 changed the unsigned char *auth_data to void *auth_data;
4095 * Fixed SHUTDOWN command to send the reply before the server
4096 is shutdown. :) Affected file silcd/command.c.
4098 * Fixed fatal bug in CONNECT command. The hostname was invalid
4099 memory and server crashed. Affected file silcd/command.c.
4101 * Fixed fatal bug in CLOSE command. The server_entry became
4102 invalid but was referenced later in the command. Affected file
4105 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Fixed fatal bug in failure packet handling. Server ignored
4108 the failure and thus crashed when it came.
4112 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4115 that the command may be executed only once in (about) 2 seconds.
4116 The old SILC_CF_LAG flag is same but allows command bursts up
4117 to five before limiting.
4119 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4120 server code. Various commands now includes the CF_LAG_STRICT
4121 flag to disallow any kind of miss-use of the command.
4123 * Fixed the silc_buffer_unformat to not to allocate any data
4124 if the length of the data is zero. It used to allocate the
4125 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4127 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Changed the format of AdminConnection configuration section
4130 in the server. Added username of the admin to the format.
4131 Affected files silcd/serverconfig.[ch].
4133 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4134 to return admin configuration data by host, username and/or
4137 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Implemented WHOWAS command to the server. Added the functions:
4141 silc_server_command_whowas_parse,
4142 silc_server_command_whowas_send_reply,
4143 silc_server_command_whowas_from_client and
4144 silc_server_command_whowas_from_server
4146 * Added <Client ID> argument to the WHOWAS command reply. Updated
4147 the protocol specs accordingly.
4149 * Implemented WHOWAS command and command_reply to the client
4152 Implemented the WHOWAS printing on the user interface.
4154 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Added new argument to the WHOWAS command reply, the real name.
4157 It is an optional argument. Updated the protocol specs.
4159 * Added SilcIDCacheDestructor callback that is registered when
4160 the SilcIDCache is allocated. The callback is called when
4161 an cache entry in the ID Cache expires, or is purged from the
4162 cache. Added into lib/silccore/idcache.[ch].
4164 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4165 to destruct the client entries when the cache entry expires.
4166 Other ID Cache's in server and in the client library ignores
4169 * If the ID Cache entry's `expire' field is zero then the entry
4170 never expires. Added boolean `expire' argument to the
4171 silc_idcache_add function in the lib/silccore/idcache.[ch].
4172 If it is TRUE the default expiry value is used.
4174 * Added silc_server_free_client_data_timeout that is registered
4175 when client disconnects. By default for 5 minutes we preserve
4176 the client entry for history - for WHOWAS command.
4178 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added support to the server to enforce that commands are not
4181 executed more than once in 2 seconds. If server receives
4182 commands from client more frequently, timeout is registered
4183 to process the commands. Affected file silcd/command.c.
4184 Added new function silc_server_command_process_timeout.
4186 * Changed NICK_NOTIFY handling in client library to check that
4187 if the client's nickname was changed, so there is no need to
4188 resolve anything from the server.
4190 * Removed error printing from the WHOIS and IDENTIFY commands.
4191 If error occurs then it is ignored silently in the client library.
4192 The application, however, may map the received error to
4193 human readable error string. The application currently maps
4194 the NO_SUCH_NICKNAME error to string.
4196 * Made the command status message public to the application. Moved
4197 them from lib/silcclient/command_reply.c to
4198 lib/silcclient/command_reply.h. The application can map the
4199 received command status to the string with the
4200 silc_client_command_status_message function.
4202 * Added check to the server to check that client's ID is same
4203 as the Source ID in the packet the client sent. They must
4206 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Added dist-bzip hook to the Makefile.am to make bzip2
4209 compressed distributions.
4211 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Server now enforces the maximum length for the nickname and
4214 the channel as protocol specification dictates. 128 bytes for
4215 nickname and 256 bytes for channel name.
4217 * Moved the WHOIS printing to the application. The client libary
4218 does not print out the WHOIS information anymore, the application
4219 must do it. Renamed silc_client_command_reply_whois_print to
4220 the silc_client_command_reply_whois_save.
4222 The client's idle time is also sent to the application now, and
4223 the idle is shown on screen.
4225 * Added silc_client_command_reply_identify_save to save the
4226 received IDENTIFY entries.
4228 * Do not check for channel private keys in message sending and
4229 reception if the channel does not have the PRIVKEY mode set.
4230 Affected file lib/silclient/client_channel.c.
4232 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4235 just surfaced after chaning the JOIN procedure.
4237 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Added silc_client_get_clients_by_list to get client entries
4240 from Client ID list, that is returned for example by JOIN
4241 and USERS command replies. The application should use this
4242 function for example when JOIN command reply is received to
4243 resolve the clients already on the channel (library does not
4244 do that anymore as USERS command reply is not used in the JOIN
4245 procedure anymore). Affected files lib/silcclient/silcapi.h and
4246 lib/silcclient/idlist.c.
4248 * JOIN command reply and USERS command reply returns now SilcBuffer
4249 pointers instead of unsigned char pointers when returning
4250 the client list and mode list.
4252 * Added <Client ID> argument to the JOIN command reply, mainly
4253 for the server to identify for which client the command was
4254 originally sent. Updated protocol specs accordingly.
4256 * Added SilcDlist private_key pointer to the SilcChannelEntry
4257 in the client to support the channel private keys. Affected
4258 file is lib/silcclient/idlist.h.
4260 * Added SilcChannelPrivateKey argument to the function
4261 silc_client_send_channel_message so that application can choose
4262 to use specific private ke if it wants to. If it is not provided,
4263 the normal channel key is used, unless private keys are set.
4264 In this case the first (key that was added first) is used
4265 as the encryption key.
4267 * Implemented the support for channel private key handling.
4268 Implemented the following functions:
4270 silc_client_add_channel_private_key,
4271 silc_client_del_channel_private_keys,
4272 silc_client_del_channel_private_key,
4273 silc_client_list_channel_private_keys and
4274 silc_client_free_channel_private_keys
4276 Affected file lib/silcclient/client_channel.c.
4278 * Added the support for the private keys in the channel message
4279 sending and encryption and in the message reception and
4280 decryption. Affected funtions are
4281 silc_client_send_channel_message and silc_client_channel_message.
4283 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added SKE's key verify callback to the client library's
4286 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4288 * Removed the statement that server (or router) must send USERS
4289 command reply when joining to the channel so that the client
4290 knows who are on the channel. Instead, the client list and
4291 client's mode list is now sent in the JOIN command reply to the
4292 client who joined channel. This is better solution.
4294 * Added function silc_server_get_users_on_channel and function
4295 silc_server_save_users_on_channel to the silcd/server.[ch].
4297 * Removed function silc_server_command_send_users from the
4300 * Do not show topic on the client library anymore. The topic is
4301 sent in the command reply notify to the application and the
4302 application must show the topic now.
4304 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Added client searching by nickname hash into the IDENTIFY and
4307 WHOIS commands in the server as they were clearly missing from
4308 them. Affected file is silcd/command.c.
4310 * Fixed a bug in private message receiving in the client library.
4311 The remote ID was freed and it wasn't supposed, now it is
4314 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Minor fix to the channel payload; allocate the data area, as it
4317 needs to be of specific length.
4319 * If the key agreement port is zero then the operating
4320 system will define the bound port. Affected files are
4321 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4323 * Added new function silc_channel_payload_decrypt into the file
4324 lib/silccore/silcchannel.[ch].
4326 * Moved the channel message etc, check from silc_packet_decrypt
4327 to applications. The library calls now a generic
4328 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4329 when the packet is either normal or special. This was done to
4330 allow more wide range of checking that was not allowed when
4331 the code was in library. Now applications can do virtually any
4332 checks to the packet and return to the library the decision how
4333 the packet should be processed. Affected files are
4334 lib/silccore/silcpacket.[ch].
4336 Added silc_server_packet_decrypt_check to the server and
4337 silc_client_packet_decrypt_check to the client library.
4339 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4340 to send with specified source and destination information.
4342 * Channel message delivery between routers was broken after the
4343 channel key distribution was fixed earlier. The channel key
4344 was used be to distributed to other routers as well which is not
4345 allowed by the protocol. Now this is fixed and channel keys
4346 really are cell specific and the channel message delivery between
4347 routers comply with the protocol specification.
4349 * Fixed various commands in server to check also the global list
4350 for the channel entry and not just the local list. The affected
4351 file silcd/command.c.
4353 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Added assert()s to buffer formatting and unformatting routines
4356 to assert (if --enable-debug) when error occurs. Affected
4357 file: lib/silcutil/silcbuffmt.c.
4359 * Changed to auto-reconnect to check whether the remote host is
4360 router and register the re-connect timeout if it is. It used
4361 to check that whether we are normal server, but router must do
4362 auto-reconnect with another router as well. Affected file
4365 * Removed the [<key len>] option from CMODE command as the cipher
4366 name decides the key length, nowadays. See the defined ciphers
4367 from the protocol specification.
4369 * Added [<hmac>] option to the CMODE command to define the HMAC
4370 for the channel. Added SILC_CMODE_HMAC channel mode.
4372 * Added [<hmac>] option for the JOIN command so that user can
4373 select which HMAC is used to compute the MACs of the channel
4376 * Added Hmac field to the Channel Message Payload. The integrity
4377 of plaintext channel messages are now protected by computing
4378 MAC of the message and attaching the MAC to the payload. The
4379 MAC is encrypted. Now, it is clear that this causes some
4380 overhead to the size of the packet but rationale for this is that
4381 now the receiver can verify whether the channel message decrypted
4382 correctly and also when private keys are set for the channel the
4383 receiver can decrypt the packet with several keys and check from
4384 the MAC which key decrypted the message correctly.
4386 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4387 lib/silccrypt/silccipher.[ch].
4389 * Added silc_hash_len to return the digest length into the
4390 lib/silcrypt/silchash.[ch].
4392 * Rewrote parts of Silc Channel Payload interface in the
4393 lib/silccore/silcchannel.[ch]. The encode function now also
4394 encrypts the packet and parse function decrypts it.
4396 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Fixed a minor formatting bug in the SKE's key material processing.
4399 It actually might have processed the keys wrong way resulting
4402 * Redefined the mandatory HMAC algorithms and added new algorithms.
4403 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4404 and hmac-md5 truncated to 96 bits. The mandatory is now
4405 hmac-sha1-96. Rest are optional (including the one that used
4406 to be mandatory). Rationale for this is that the truncated HMAC
4407 length is sufficient from security point of view and can actually
4408 make the attack against the HMAC harder. Also, the truncated
4409 HMAC causes less overhead to the packets. See the RFC2104 for
4412 * Added new [hmac] configuration section. The SKE used to use
4413 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4414 is of course wrong. The official names that must be proposed in
4415 the SKE are the ones defined in the protocol specification
4416 (hmac-sha1-96 for example). The user can configure any hmac
4417 using any hash function configured in the [hash] section. At
4418 least, the mandatory must be configured.
4420 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4422 * Added HMAC list to the SKE proposal list. It has now both
4423 hash algorithm list and HMAC list. This makes the protocol
4424 incompatible with previous versions. The SKE now seems to work
4425 the way it is supposed to work, for the first time actually.
4427 * Defined plain Hash algorithms to the protocol specification.
4430 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Implemented support for key agreement packets into the server.
4433 Added functions silc_server_key_agreement and
4434 silc_server_send_key_agreement. Other than these functions,
4435 server has nothing to do with this packet.
4437 * Added support for private message key packets into the server.
4438 Added functions silc_server_private_message_key and
4439 silc_server_send_private_message_key.
4443 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4444 called in the protocol's final callback instead in the END
4445 protocol state. This makes a little more sense and in the same
4446 time in client we can use the same protocol routines for normal
4447 key exchange and to key agreement packet handling as well.
4449 * Added to both client's and server's KE protocol context the
4450 SilcSKEKeyMaterial pointer to save the key material. We will
4451 bring the key material to the protocol's final callback by doing
4452 this. The final callback must free the key material.
4454 * Added SKE's packet_send callback into client's KE protocol
4455 context so that the caller can choose what packet sending function
4456 is used. This way we can use different packet sending when
4457 doing normal SKE when doing key agreement packet handling (in
4458 the key agreement packet handling we do not want to encrypt
4461 * Implemented the responder side of the key agreement routines
4462 in the client. The client can now bind to specified port and
4463 accept incoming key negotiation. The key material is passed
4464 to the application after the protocol is over.
4466 * Implemented the processing of incoming Key Agreement packet
4467 in the client. Added function silc_client_key_agreement to
4470 * Implemented the intiator side of the key agreement routines
4471 in the client. The client can now initiate key agreement with
4472 another remote client. The key material is passed to the
4473 application after the protocol is over.
4475 * Created client_keyagr.c to include all the key agreement
4478 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4479 SILC_TASK_CALLBACK except that it is not static.
4481 * Created client_notify.c and moved the Notify packet handling
4482 from the client.[ch] into that file.
4484 * Created client_prvmsg.c and moved all private message and
4485 private message key routines from the client.[ch] into that file.
4487 * Create client_channel.c and moved all channel message and
4488 channel private key routines from the client.[ch] into that file.
4490 * Changed silc_client_get_client_by_id_resolve to resolve with
4491 WHOIS command instead of IDENTIFY command, in the file
4492 lib/silclient/idlist.c.
4494 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Implemented the SKE's responder side to the Client library.
4498 * When FAILURE is received to the protocol do not trust it
4499 blindly. Register a timeout to wait whether the remote closes
4500 the connection as it should do it, only after that process the
4501 actual failure. This was changed to both client and server.
4503 * Added client_internal.h to include some of the structures
4504 there instead of client.h in lib/silcclient/.
4506 * Added function silc_task_unregister_by_callback to unregister
4507 timeouts by the callback function.
4509 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Some "Incomplete WHOIS info" errors has been appearing on the
4512 log files. Took away the entry->userinfo check from WHOIS
4513 reply sending. The entry->userinfo is now " " if client did not
4514 provide one. I thought this was fixed earlier but something
4515 is wrong still. Let's see if the error still appears.
4517 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Fixed a minor bug in the login when the channel key is
4520 re-generated in the server. It used to generate the key in
4521 wrong order and thus caused problems in the channel traffic.
4523 * Fixed a minor bug in channel key distsribution after
4524 KICK command. The key was not sent to the router even though
4527 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Added silc_ske_process_key_material_data as generic routine
4530 to process any key material as the SILC protocol dictates. The
4531 function is used by the actual SKE library but can be used by
4532 applications as well. This relates to the private message keys
4533 and the channel private keys since they must be processed the
4534 same way the normal SILC session keys. The protocol dictates
4535 this. Affected files: lib/silcske/silcske.[ch].
4537 Added also silc_ske_free_key_material to free the
4538 SilcSKEKeyMaterial structure.
4540 * Defined silc_cipher_set_key function to set the key for
4541 cipher without using the object's method function. The affected
4542 files: lib/silccrypt/silccipher.[ch].
4544 * Implemented silc silc_client_add_private_message_key,
4545 silc_client_add_private_message_key_ske,
4546 silc_client_del_private_message_key,
4547 silc_client_list_private_message_keys and
4548 silc_client_free_private_message_keys functions in the
4551 Added functions silc_client_send_private_message_key to send
4552 the Private Message Key payload and silc_client_private_message_key
4553 to handle incoming Private Message Key payload.
4555 * Added Cipher field to the Private Message Key payload to set
4556 the cipher to be used. If ignored, the default cipher defined
4557 in the SILC protocol (aes-256-cbc) is used.
4559 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Removed lib/silcclient/ops.h file.
4563 Redefined parts of the SILC Client Library API. Created new
4564 file silcapi.h that deprecates the ops.h file and defines the
4565 published Client Library API. Defined also private message key
4566 API and channel private key API into the file.
4568 This is the file that the application must include from the
4569 SILC Client Library. Other files need not be included by
4570 the application anymore.
4572 * Added new key_agreement client operation callback and also
4573 defined the Key Agreement library API for the application.
4575 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4578 is used by clients to request key negotiation between another
4579 client in the SILC network. If the negotiation is started it
4580 is performed using the SKE protocol. The result of the
4581 negotiation, the secret key material, can be used for example
4582 as private message key.
4584 Implemented the Key Agreement payload into the files
4585 lib/silccore/silauth.[ch].
4587 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Redefined ciphers for the SILC protocol. Added some new ciphers
4590 and defined the key lengths for the algorithms. Changed the
4591 code accordingly. The default key length is now 256 bits.
4593 * Fixed SKE key distribution function silc_ske_process_key_material
4594 when the key length is more than 128 bits. The default key
4595 length in SILC is now 256 bits.
4597 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4598 to indicate unsupported algorithm.
4600 * Renamed rijndael.c to aes.c and all functions as well.
4602 * Fixed a long standing channel key setting bug in client library.
4603 Weird that it has never surfaced before.
4605 * Fixed bug in channel deletion. If the entire channel is removed
4606 then it must also delete the references of the channel entry
4607 from the client's channel list as the client's channel entry and
4608 the channel's client entry share same memory.
4610 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Implemented CONNECT and SHUTDOWN commands in the client.
4614 * Implemented CLOSE command to the client.
4616 * Added the function silc_idlist_find_server_by_name into the
4617 files silcd/idlist.[ch].
4619 Added the function silc_idlist_find_server_by_conn into the
4620 files silcd/idlist.[ch].
4622 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * DIE command was renamed to SHUTDOWN. Updated the both code
4627 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4628 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4630 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4633 * Added function silc_server_create_connection function to create
4634 connection to remote router. My server implementation actually
4635 does not allow router to connect to normal server (it expects
4636 that normal server always initiates the connection to the router)
4637 so the CONNECT command is only good for connecting to another
4640 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4643 or some other client was kicked from the channel.
4645 Implemented the handling of the notify type to both client
4648 Implemented silc_server_send_notify_kicked to send the KICKED
4649 notify. It is used to send it to the server's primary router.
4651 * Implemented the KICK command into server and client.
4653 * Added `query' argument to the silc_idlist_get_client function
4654 to indicate whether to query the client from server or not if
4657 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4658 to indicate that the client is not channel founder.
4662 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Removed the rng context from SilcPacketContext structure and
4665 changed that the packet routine uses the Global RNG API.
4667 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added support for quit message that client can "leave" on the
4670 channel when it quits the SILC. It is ditributed inside the
4671 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4673 Added silc_server_free_client_data that will take the
4674 signoff message as argument.
4676 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4678 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Updated parts of the protocol specification to keep it up
4683 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4686 payloads in one packet.
4688 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4689 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4690 use now the new List flag.
4692 * Also deprecated the following packet types: REPLACE_ID,
4693 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4695 * Added list support for Notify packet in server.
4697 * Added silc_server_send_notify_channel_change to send the
4698 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4699 the silc_server_send_replace_id.
4701 * Added silc_server_send_notify_nick_change to send the
4702 NICK_CHANGE notify type. Deprecates the function
4703 silc_server_send_replace_id.
4705 * Added silc_server_send_notify_join to send the JOIN notify type.
4706 Deprecates the function silc_server_send_new_channel_user.
4708 * Added silc_server_send_notify_leave to send LEAVE notify type.
4709 Deprecates the function silc_server_send_remove_channel_user.
4711 * Added silc_server_send_notify_cmode and
4712 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4713 types. Deprecates the silc_server_send_set_mode function.
4715 * Added SERVER_SIGNOFF notify type to indicate that server has
4716 quit. This means that all clients on the channel from that
4717 server will drop. This can be also used when netsplit happens.
4719 Deprecated REMOVE_ID packet type since it is not needed anymore
4722 Added silc_server_send_notify_server_signoff to send the
4723 SERVER_SIGNOFF notify type. Deprecates the function
4724 silc_server_send_remove_id.
4726 Added also silc_server_send_notify_signoff to send the
4727 SIGNOFF notify type.
4729 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4730 SILC protocol from this day on. Changed the protocol
4731 specification as well.
4733 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4734 notify type. It is used between routers to notify about
4735 topic changes on a channel.
4737 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4740 * Partly updated the protocol specification to comply with the
4741 changes now made. It is still though a bit outdated.
4743 * The JOIN notify type now takes one extra argument <Channel ID>.
4744 The packet used to be destined to the channel but now the
4745 JOIN type may be sent as list thus it is impossible to
4746 destine it to any specific channel. By adding this argument
4747 it is again possible.
4749 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Added CREDITS file. The CHANGES and CREDITS file will appear
4752 in the distribution as well.
4754 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4757 types in the server's silcd/packet_receive.c.
4759 * Implemented CMODE and CUMODE to work in router environment.
4761 * Fixed minor encoding and decoding buglet from the
4762 lib/silccore/silcmode.c.
4764 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4767 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4769 * Changed all SilcConfigServer* and silc_config_server* to
4770 SilcServerConfig* and silc_server_config*, respectively.
4773 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Associated the ID (client or server ID) to the Authentication
4776 Payload to avoid any possibility of forging. Updated the
4777 protocol specification and the code accordingly.
4779 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * The RSA key length is now save to the RsaKey context in the
4782 key generation process in lib/silccrypt/rsa.c. The key length
4783 is now used to figure out the maximum size of the block allowed
4784 to be encrypted/signed.
4786 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4787 is equivalent to the silc_mp_mp2bin but does not allocate any
4790 * Changed silc_mp_mp2bin API to take length argument. If it is
4791 non-zero then the buffer is allocated that large. If zero, then
4792 the size is approximated using silc_mp_sizeinbase, which however
4795 * Created Global RNG API which is global RNG that application can
4796 initialize. After initializing, any routine anywhere in the
4797 code (including library) can use RNG without allocating a new
4798 RNG object. This was done to allow this sort of use of the
4799 RNG in code that has no chance to allocate RNG object. All
4800 applications currently allocate this and many routines in the
4801 library use this. Affected file lib/silccrypt/silcrng.[ch].
4803 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4804 it to use the Global RNG API.
4806 * Defined Authentication Payload into protocol specification that
4807 is used during SILC session to authenticate entities. It is
4808 used for example by client to authenticate itself to the server
4809 to obtain server operator privileges.
4811 Implemented this payload into the lib/silccore/silcauth.[ch].
4812 Implemented also routines for public key based authentication
4813 as the new protocol specification dictates.
4815 Moved definitions of different authentication methods from
4816 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4818 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4819 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4820 silc_pkcs_verify_with_hash functions into the file
4821 lib/silccrypt/silcpkcs.[ch].
4823 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * The client entry's userinfo pointer must be always valid.
4826 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4827 will fail since it requires the userinfo. Now, the userinfo
4828 is allocated as "" if actual userinfo does not exist. Actually,
4829 it must exist and it is totally Ok to drop client connections
4830 that does not announce the userinfo. However, we will make
4831 this workaround for now.
4833 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4834 to return the remote port by socket.
4836 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4839 SILC_SERVER_PENDING_EXEC and added an new macro
4840 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4841 data or when error occurs while processing the pending command.
4843 Added new argument `destructor' into silc_server_command_pending
4844 and to the SilcServerCommandPending object. This destructor is
4845 now called after calling the pending callback or if error occurs
4846 immediately. If error occurs the actual pending callback won't
4847 be called at all - only the destructor. The destructor may be
4848 NULL if destructor is not needed.
4850 All this applies for client library code as well. Similar
4851 changes were made there as well for the pending commands.
4853 In the client, the application must now allocate the
4854 SilcClientCommandContext with the silc_client_command_alloc
4857 * Added reference counter to the SilcServerCommandContext. Added
4858 function silc_server_command_alloc and silc_server_command_dup
4861 Same type of functions added to the client library for the same
4864 * Removed the cmd_ident from IDListData away since it is now
4865 global for all connections. It is the command identifier used
4866 in command sending and with pending commands. The affected file
4869 * Added reference counter to the SilcSocketConnection objecet to
4870 indicate the usage count of the object. The object won't be
4871 freed untill the reference counter hits zero. Currently only
4872 server uses this, and client ignores it. The client must be
4873 set to use this too later. The affected files are
4874 lib/silccore/silcsockconn.[ch]. Added also the function
4875 silc_socket_dup to increase the reference counter.
4877 This was mainly added because it is possible that the socket
4878 is removed underneath of pending command or other async
4879 operation. Now it won't be free'd and proper DISCONNECTING
4880 flags, etc. can be set to avoid sending data to connection that
4881 is not valid anymore.
4883 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4884 the connection. After that it sets SILC_SET_DISCONNECTED.
4885 It is, however, possible that the socket data is not still freed.
4886 The silc_server_packet_process now checks that data is not
4887 read or written to connection that is DISCONNECTED. The socket
4888 get's freed when the reference counter hits zero.
4890 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Changed the client operation API: channel_message operation's
4893 `sender' is now the client entry of the sender, not the nickname
4894 and the `channel' is the channel entry, not the channel name.
4896 In the private_message operation the `sender' is now also the
4897 client entry of the sender not the nickname.
4899 Affected file is lib/silcclient/ops.h and all applications
4900 using the client operations.
4902 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Moved the calling of ops->connect() from connect_to_server_final
4905 into receive_new_id functin since that is the point when the
4906 client is actually allowed to send traffic to network. The
4907 affected file is lib/silcclient/client.c.
4909 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4912 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4913 (if needs broadcasting) instead of broadcasting the packets one
4914 by one which would make a burst in the network traffic.
4916 * Added `broadcast' argument to the functions in silcd/server.[ch]
4917 silc_server_create_new_channel[_with_id] to indicate whether
4918 to send New Channel packet to primary router.
4920 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Added new function into the silcd/server.[ch] files:
4923 silc_server_create_new_channel_with_id to create new channel with
4924 already existing Channel ID.
4926 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4927 lib/silccore/silcpacket.h. This packet is used t send list of
4928 Set Mode payloads inside one packet. Server uses this to set
4929 the modes for the channels and clients on those channels, that it
4930 announced to the router when it connected to it. The protocol
4931 specification has been updated accordingly.
4933 * The silc_server_new_channel did not handle the packet coming
4934 from normal server as it normally does not send that. However,
4935 when it announces its channels it does send it. Implemented
4936 the support for that.
4938 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4939 into the file lib/silccore/id.h.
4941 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Fixed memory leaks in the functions silc_idlist_del_client,
4944 silc_idlist_del_channel and silc_idlist_del_server in the file
4945 silcd/idlist.c. All of those leaked like a sieve.
4947 * Fixed some small memory leaks in the client's function
4948 silc_client_notify_by_server.
4950 * Added functions into silcd/server.c: silc_server_announce_clients,
4951 silc_server_announce_channels and silc_server_announce_server.
4952 These functions are used by normal and router server to announce
4953 to its primary router about clients, channels and servers (when
4954 router) that we own. This is done after we've connected to the
4957 These functions effectively implements the following packet types:
4958 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4959 and SILC_PACKET_NEW_ID_LIST.
4961 * Added new functions into the silcd/packet_receive.[ch]:
4962 silc_server_new_id_list, silc_server_new_channel_list and
4963 silc_server_new_channel_user_list to handle the incoming
4964 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4966 * Added support of changing Channel ID in the function
4967 silc_server_replace_id. If the server that announces a channel
4968 to the router already exists in the router (with same name but
4969 with different Channel ID), router is responsible to send
4970 Replace ID packet to the server and force the server to change
4971 the Channel ID to the one router has.
4973 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4974 client that the Channel ID has been changed by the router. The
4975 normal server sends this to the client. Client must start using
4976 the new Channel ID as the channel's ID.
4978 Implemented handling of this new type into lib/silcclient/client.c
4979 into the function silc_client_notify_by_server.
4981 * Added new function silc_idlist_replace_channel_id into the files
4982 silcd/idlist.[ch] to replace the Channel ID.
4984 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Call silc_server_command_identify_check always when processing
4987 the IDENTIFY command in silcd/command.c
4989 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4992 send keepalive packets. The packet can be sent by clients,
4993 servers and routers.
4995 Added function silc_socket_set_heartbeat into the file
4996 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4997 If not set, the heartbeat is not performed. The actual
4998 heartbeat is implemented in the low level socket connection
4999 library. However, application is responsible of actually
5002 Added silc_server_send_heartbeat to send the actual heartbeat
5003 packet into silcd/packet_send.[ch]. Server now performs
5004 keepalive with all connections.
5006 * Added silc_task_get_first function into lib/silcutil/silctask.c
5007 to return the timeout task with shortest timeout. There was a bug
5008 in task unregistration that caused problems. TODO has been
5009 updated to include that task system must be rewritten.
5011 * The client library will now resolve the client information when
5012 receiving JOIN notify from server for client that we know but
5013 have incomplete information.
5015 * Rewrote parts of silc_server_remove_from_channels and
5016 silc_server_remove_from_one_channel as they did not remove the
5017 channel in some circumstances even though they should've.
5019 * Encryption problem encountered in server:
5021 The LEAVE command used to send the Channel Key packet to the
5022 router immediately after generating it. However, the code
5023 had earlier sent Remove Channel user packet but not immediately,
5024 ie. it was put to queue. The order of packets in the router
5025 was that Channel Key packet was first and Remove Channel User
5026 packet was second, even though they were encrypted in the
5027 reverse order. For this reason, MAC check failed. Now, this
5028 is fixed by not sending the Channel Key packet immediately but
5029 putting it to queue. However, this is more fundamental problem:
5030 packets that are in queue should actually not be encrypted
5031 because packets that are sent immediately gets encrypted
5032 actually with wrong IV (and thus MAC check fails). So, packets
5033 that are in queue should be encrypted when they are sent to
5034 the wire and not when they put to the queue.
5036 However, the problem is that the current system has not been
5037 designed to work that way. Instead, the packet is encrypted
5038 as soon as possible and left to the queue. The queue is then
5039 just purged into wire. There won't be any fixes for this
5040 any time soon. So, the current semantic for packet sending
5043 o If you send packet to remote host and do not force the send
5044 (the packet will be in queue) then all subsequent packets to the
5045 same remote host must also be put to the queue. Only after the
5046 queue has been purged is it safe again to force the packet
5049 o If you send all packets immediately then it safe to send
5050 any of subsequent packets through the queue, however, after
5051 the first packet is put to queue then any subsequent packets
5052 must also be put to the queue.
5054 Follow these rules and everything works fine.
5056 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added new function silc_server_remove_clients_by_server to
5059 remove all client entries from ID list when the server connection
5060 is lost. In this case it is also important to invalidate all
5061 client entires as they hold the invalid server entry. This
5062 fixes fatal bug when server has lost connection and will reconnect
5065 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Made some sanity checks to silc_server_daemonise like to check
5068 whether the requested user and group actually exists.
5070 * Added sanity check to SKE's silc_ske_responder_finish to check
5071 that the public and private key actually is valid.
5073 * Invalidate the client's nickname when receiving Replace ID
5074 packet and the Client ID is being replaced. This means that the
5075 server will query the nickname if someone needs it (client)
5078 * Sort the ID Cache in client library when the ID Cache data
5079 has changed (needs sorting).
5081 * Do not allow for SILC client to create several connections to
5082 several servers. The client does not support windows right now
5083 and generating multiple connections causes weird behaviour.
5085 Irssi-silc client does support windows and can handle several
5086 connections without problems, see: www.irssi.org and SILC plugin.
5088 * Fixed some places where client was added to the IDList. The
5089 rule of thumb is following (in order to get everything right):
5090 If the client is directly connected local client then the
5091 `connection' argument must be set and `router' argument must be
5092 NULL to silc_idlist_add_client function. If the client is not
5093 directly connected client then the `router' argument must
5094 bet set and the `connection' argument must be NULL to the
5095 silc_idlist_add_client function.
5097 * The funtion silc_server_packet_send_local_channel actually did
5098 not check whether the client was locally connected or not. It
5099 does that now. Fixed a bug related to LEAVE command.
5101 * Fixed Remove Channel User payload parsing bug in server's
5102 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5104 * The server's silc_server_save_channel_key now checks also the
5105 global ID list for the channel as it might not be in the local
5106 list. Fixed a bug related to LEAVE command.
5108 * Is this the end of the [<unknown>] buglet that has been lurking
5109 around for a long time? A little for loop fix in server's
5110 silc_server_command_whois_parse that is used by both IDENTIFY
5111 and WHOIS command. At least, this was a clear bug and a cause
5112 of one type of [<unknown>] buglet.
5114 * WHOIS and IDENTIFY commands call the function
5115 silc_server_command_[whois/identify]_check function even if
5116 we are not router server.
5118 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Added --with-gmp configuration option. If set the GMP
5121 is always compiled in the SILC source tree. If not set then
5122 it is checked whether the system has the GMP3 installed. If
5123 it has then the GMP won't be compiled (the system's headers
5124 and library is used), if it doesn't have it then the GMP is
5125 compiled in the SILC source tree.
5127 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Changed RSA private exponent generation to what PKCS #1
5130 suggests. We try to find the smallest possible d by doing
5131 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5132 not security fix but optimization.
5134 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Added new config entry [Identity] to fork the server and run
5137 it as specific user and group. A patch from Bostik.
5139 * Imported Dotconf configuration library into lib/dotconf.
5140 This will be used to create the SILC configuration files later.
5141 It will appear in the distsribution after this commit.
5143 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * A big code auditing weekend happening. Auditing code for
5146 obvious mistakes, bugs and errors. Also, removing any code
5149 Removed files for being obsolete:
5151 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5152 inline in the file lib/silcutil/silcbuffer.h)
5154 o lib/silcutil/silcbufutil.c (the header has inline versions)
5156 Changed code to fix possible error conditions:
5158 o The buffer formatting routines now check that the destination
5159 buffer really has enough space to add the data. This applies for
5160 both buffer formatting and unformatting
5161 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5162 unformatting was changed to accomodate following rules:
5163 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5164 sent to the function while XXX_*STRING will not allocate or copy
5165 the data into the buffer. Instead it sets the pointer from the
5166 buffer into the pointer sent as argument (XXX_*STRING used to
5167 require that the pointer must be allocated already). This change
5168 makes this whole thing a bit more consistent and more optimized
5169 (note that the data returned in the unformatting with XXX_*STRING
5170 must not be freed now). The routines return now -1 on error.
5172 o Tried to find all code that use buffer_format and buffer_unformat
5173 and added return value checking to prevent formatting and
5174 especially unformatting errors and possible subsequent fatal
5177 o Changed ske->x and ske->KEY to mallocated pointers in
5178 lib/silcske/silcske.h. Fixed possible data and memory leak.
5180 o Added return value checking to all *_parse* functions. Fixed
5181 many memory leaks as well.
5183 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5184 so that buffer overflows would not happen. All code now also
5185 checks the return value as it can fail.
5187 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added reconnection support to server if the normal server looses
5190 its connection to the router (for example if router is rebooted).
5191 The server performs normal reconnection strategy implemented
5192 to the server. Affected file silcd/server.c.
5194 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Added new packet type SILC_PACKET_SET_MODE that is used to
5197 distribute the information about changed modes (for clients,
5198 channels and clients channel modes) to all routers in the
5199 network. Updated the protocol specification accordingly.
5201 Added functions into silcd/packet_send.c and
5202 silcd/packet_receive.c: silc_server_send_set_mode,
5203 silc_server_set_mode.
5205 Added new files silcmode.[ch] into lib/silccore that implements
5206 the encoding and decoding of Set Mode Payload. Added new type
5207 SilcSetModePayload. Moved the definitions of different modes
5208 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5210 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5212 * Oops, a little mistake in server's connection authentication
5213 protocol. The protocol is not ended with FAILURE but with
5214 SUCCESS if the authentication is Ok. :) Affected file is
5217 * Implemented NICK_CHANGE notify handling in server in the file
5218 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5219 the local clients on the channel. After the changing nickname
5220 in router environment snhould work and the [<unknown>] nickname
5221 should appear no more.
5223 The silc_server_replace_id function that receives the Replace ID
5224 payload now sends the NICK_CHANGE notify type also in the file
5225 silcd/packet_receive.c
5227 * Changed WHOIS and IDENTIFY command to support the maximum amount
5228 of arguments defined in protocol specs (3328 arguments). This
5229 fixed a bug that caused problems when there were more than three
5232 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Added extra parameter, command identifier, to the
5235 silc_client_send_command so that explicit command identifier
5238 Changed that ID list routines uses specific command identifier
5239 when sending WHOIS/IDENTIFY requests to the server so that they
5240 can be identified when the reply comes back.
5242 Affected files lib/silcclient/command.[ch],
5243 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5245 * Added `sender' argument to silc_server_packet_send_to_channel
5246 to indicaet the sender who originally sent the packet to us
5247 that we are now re-sending. Ignored if NULL. Affected file
5248 silcd/packet_send.[ch].
5250 * Added some server statistics support in silcd/server_internal.h
5251 SilcServerStatistics structure and around the server code. Also
5252 send some nice statistics information when client is connecting
5255 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Fixed channel ID decoding in server's JOIN command reply in
5258 silcd/command_reply.c
5260 * Fixed braodcasting of replace ID payload to not to send it if
5261 we are standalone server in silcd/packet_receive.c.
5263 * Fixed all channel message sending routines to not to send
5264 packets to clients that has router set, since they are routed
5265 separately in the same function earlier. Affects file
5266 silcd/packet_send.c and all channel packet sending functions.
5268 * In USERS reply, res_argv[i] are not allocated, the table
5269 is allocated. Thus changed that free the table, not its
5272 * In server's whois_check and identify_check if the client is
5273 locally connected do not send any WHOIS commands - they are not
5276 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Fixed some minor bugs in client when sending WHOIS command. The
5279 arguments was in wrong order.
5281 * Removed statis function add_to_channel from server in
5282 silcd/command.c that was previously used with the joining but
5285 * Tested USERS command in router environment successfully with two
5286 routers, two servers and two clients.
5288 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Reorganized the USERS command and command reply in client library
5291 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5292 When the command is given by user we register a pending command
5293 callback that will reprocess the command after the reply has been
5294 received from the server. When reprocessing the packet we then
5295 display the information. Thus, the USERS information is displayed
5296 now in the command callback instead of in the command reply
5297 callback. The processing of the command is same as previously
5298 when server has sent the command reply in the JOINing process.
5300 * Added to USERS command in silcd/command_reply.c to join the client,
5301 we didn't use to know about, to the channel after we've created
5302 a client entry for it. Also, for clienet we did know already still
5303 check whether it is on the channel or not and add it if not.
5305 * Removed silc_server_command_join_notify as the function and its
5308 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Changed the client's pending command handling to the same as the
5311 server's pending command handling. It is also now possible to
5312 execute command reply functions from other command reply
5313 function as the function callbacks for commands and command
5314 replies are one and same. The pending commands are not static
5315 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5316 in client connection context. Thus, pending commands are server
5317 connection specific as it is convenient.
5319 Changed the function silc_client_command_pending and
5320 silc_client_command_pending_del and added new function
5321 silc_client_command_pending_check. Removed the
5322 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5325 * Added cmd_ident, current command identifier, to the client
5326 connection context in lib/silcclient/client.h to keep track on
5327 command identifiers used in command sending. Client's command reply
5328 function handling now supports the mandatory command identifiers.
5330 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5331 funtions in client to fully support pending command callbacks.
5333 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5334 as one of the arguments to the application in the command reply
5337 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5338 before first releasing SILC but came back. Now it is removed again
5339 and should come back nomore. The FORWARDED flag was used only
5340 by the JOINing procedure by forwarding the command packet to router.
5341 Now, the JOINing procedure has been changed to more generic (due
5342 to various router environment issues) and FORWARDED is not needed
5343 anymore for anything. The protocol specification is yet to be
5346 Now, removed silc_server_packet_forward from server and the flag
5347 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5349 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Renamed NAMES command to USERS command. The NAMES was named that
5352 due to historical reasons. Now it is renamed. Also, rewrote
5353 parts of the USERS command. The nickname list is not sent anymore
5354 by the server. Only Client ID and mode lists are sent in the USERS
5355 command. Changed this also to the protocol specification.
5357 The client now resolves the names and stuff after it receives
5358 the USERS list from the server when joining to the channel.
5360 * WHOIS and IDENTIFY commands has been changed to support multiple
5361 Client ID's per command. One can now search for multiple users
5362 in the network by sending only one WHOIS or IDENTIFY command.
5363 Changed the code and the protocol specifications.
5365 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5366 uses silc_server_command_whois_parse to parse the request. */
5368 * If normal server, do not parse the WHOIS and IDENTIFY requests
5369 before sending it to the router. Saves some time.
5371 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Fixed JOIN command on client library. Wrong number of arguments
5374 used to crash the client.
5376 * Added silc_server_channel_has_global function to check whether
5377 channel has global users or not.
5379 * Added silc_server_channel_has_local function to check whether channel
5380 has locally connected clients on the channel.
5382 * The silc_server_remove_from_one_channel now checks whether the
5383 channel has global users or not after given client was removed from
5384 the channel. It also checks whether the channel has local clients
5385 on the channel anymore. If it does not have then the channel entry
5386 is removed as it is not needed anymore.
5388 * The silc_server_notify now checks on JOIN notify whether the joining
5389 client is one of locally connected or global. If it is global then
5390 the channel has now global users on the channel and that is marked
5391 to the channel entry. Also, it now saves the global client to
5392 global list who is joining and JOINs it to the channel. This is
5393 for normal server, that is.
5395 Changed silc_server_send_notify_on_channel,
5396 silc_server_packet_relay_to_channel and
5397 silc_server_packet_send_to_channel check if we are normal server
5398 and client has router set (ie. global client) do not send the
5399 message to that client, as it is already routed to our router.
5401 * Implemented LEAVE notify type handling in silc_server_notify
5404 * Tested LEAVE command in router environment successfully. Tested
5405 with two routers, two servers and two clients.
5409 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5411 * Implemented SIGNOFF notify type handling in silc_server_notify
5414 * silc_server_remove_id now removes the client entry from all channels
5415 it has joined and thusly sends SIGNOFF notify type.
5417 * Rewrote the NAMES list generation in server by removing two excess
5418 loops. The lists are created now inside one loop.
5420 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * silc_server_remove_channel_user checks now also global list
5423 for channel and client.
5425 * silc_server_new_channel_user checks now both local and global
5426 list for channel and client. Fixed a bug in client id decoding.
5427 Used to decode wrong buffer.
5429 * silc_server_channel_message checks now both local and global
5430 list for channel entry.
5432 * Tested channel joining (hence JOIN) in router environment
5433 successfully. Tested with two routers, two servers and two
5436 * Tested channel message sending in router environment successfully.
5438 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Added silc_server_save_channel_key into server.[ch] to save the
5441 received channel key in Channel Key payload processing. It is
5442 also used in JOIN command reply handling.
5444 Equivalent function silc_client_save_channel_key added into
5445 client.[ch] into client library.
5447 * Changed JOIN command reply to send information whether the channel
5448 was created or not (is existing already) and the channel key
5449 payload. Changed protocol specs accordingly.
5451 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5452 the request was sent by ID and not by nickname. Crashed on
5455 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5458 now correctly save the received data.
5460 * silc_server_free_sock_user_data now notifies routers in the
5461 network about entities leaving the network.
5463 At the same time implemented functions silc_server_remove_id
5464 and silc_server_send_remove_id to receive and send REMOVE_ID
5465 packets. The packet is used to notify routers in the network
5466 about leaving entities. The ID removed will become invalid in
5469 * Added function silc_idlist_del_server into server. Removes and
5470 free's server entry from ID list.
5472 * silc_server_private_message function now checks, if we are router,
5473 that the destination ID really is valid ID, naturally.
5475 * In router when NEW_ID packet is received (for new client) the
5476 hash of the Client ID is saved in the ID Cache but the
5477 client->nickname is set to NULL, instead of putting the hash
5480 IDENTIFY command now also checks that client->nickname must be
5481 valid. If it is not if will request the data from the server who
5482 owns the client. Added new function
5483 silc_server_command_identify_check.
5485 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5486 to set the command to already allocated Command Payload.
5488 * Tested private message sending in router environment with two
5489 routers, two servers and two clients. Fixed minor bugs and now
5492 * Fixed segfault from client's NAMES command. Used to crash if
5495 * Forwarded packets must not be routed even if it is not destined
5496 to the receiver. Changed server code comply with this.
5498 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added `require_reverse_mapping' boolean value to ServerParams
5501 structure. If TRUE (not default) the server will require that
5502 the connecting host has fully qualified domain name.
5504 If the reverse mapping is not required and hostname could not be
5505 found the IP address is used as hostname.
5507 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5509 * Implemented version string checking to both client and server.
5510 The check is incomplete currently due to the abnormal version
5511 strings used in development version of SILC.
5513 * Changed all command functions in server to use the new
5516 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Changed char *data to unsigned char *data in ID Cache system to
5519 support binary data as ID Cache data. Changed code to support
5520 binary data in lib/silccore/idcache.c.
5522 * Renamed silc_server_packet_relay_command_reply to
5523 silc_server_command_reply as it is normal packet receiving
5524 function. Rewrote the function to accept command replys for
5525 servers and not only for clients.
5527 * Mark remote router always as registered server if we are connecting
5528 to it. Otherwise, commands sent by the router to us are ignored.
5530 * All ID List find routines now returns the ID Cache Entry pointer
5531 as well if requested.
5533 * WHOIS command works now in router environment, tested with two
5534 routers, two servers and two clients.
5536 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5537 in router environment (as it is almost equivalent to WHOIS) but
5538 hasn't been tested thoroughly. Added new functions:
5540 silc_server_command_identify_parse
5541 silc_server_command_identify_send_reply
5542 silc_server_command_identify_from_client
5543 silc_server_command_identify_from_server
5545 * Disabled route cache adding because adding two different ID's with
5546 same IP replaces the old cache entry thus giving wrong route.
5547 The entry->router->connection is always the fastest route anyway
5548 so route cache may not be needed. Of course, new routes maybe
5549 established after receiving the ID when the entry->router->connection
5550 might not be anymore the most optimal.
5552 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Add route cache for received ID for fast routing.
5556 * Added silc_server_packet_route to route received packet on router
5557 that is not destined to us.
5559 * Renamed silc_server_get_route to silc_server_route_get.
5561 * Added id_string and id_string_len fields into SilcServer to
5562 include encoded ServerID for fast comparing without excess
5563 encoding of the ID's.
5565 * Cleaned up WHOIS command on server side. Added following static
5568 silc_server_command_whois_parse
5569 silc_server_command_whois_check
5570 silc_server_command_whois_send_reply
5571 silc_server_command_whois_from_client
5572 silc_server_command_whois_from_server
5574 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5575 arguments in command replies. All command functions should be
5576 updated to use this macro.
5578 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Minor typo fixes on command reply handling on server.
5582 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Added silc_server_command_add_to_channel internal routine to add
5585 the client to the channel after router has created the channel and
5586 sent command reply to the server.
5588 * Added generic silc_server_send_command to send any command from
5591 * Use static buffer with ID rendering instead of duplicating data.
5593 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Fixed a channel user mode bug when joining to a channel server gave
5596 everybody channel founder rights, oops.
5598 * We mark ourselves as the router of the incoming server connection
5599 if we are router ourselves. This way we can check in some packet
5600 sending functions whether it is locally connected server. For
5601 incoming router connections we put NULL.
5603 * For router sending packets locally means now always sending the
5604 packet cell wide; to local clients and local servers. For normal
5605 server sending packet locally means sending it to only local
5608 * Fixed the JOIN command to really work in router environment. If the
5609 channel is created it is always created by the router. Router is
5610 also responsible of making the initial joining to the channel,
5611 sending JOIN notify to the sending server and distributing
5612 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5613 does not exist server doesn't do anything else but forward the
5614 command to the router which performs everything.
5616 * Added silc_server_send_channel_key function to send the Channel Key
5619 * Added silc_server_create_channel_key to create new channel key. The
5620 channel key is now re-generated everytime someone joins or leaves
5621 a channel, as protocol dictates. Note: channel->key_len is the
5624 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5627 packet_receive.[ch] to separate packet sending and receiving
5628 routines. The server.[ch] now includes everything else including
5629 actual packet processing (writing and reading data) and other
5632 Renamed silc_server_private_message_send_internal to
5633 silc_server_send_private_message. The routine is still though
5634 used only to relay private messages as server does not send
5635 private messages itself.
5637 Renamed silc_server_new_channel to silc_server_create_new_channel
5638 and added new function sicl_server_new_channel that handles the
5639 incoming New Channel packet. Added also new sending function
5640 silc_server_send_new_channel to send New Channel Payload.
5642 * Added new function silc_server_notify to process incoming notify
5643 packet to the server/router. Server may then relay the notify
5644 to clients if needed.
5646 * Added new function silc_server_new_channel_user to process incoming
5647 New Channel User packet. Router will redistribute the packet and
5648 send JOIN notify to its local clients and locally connected servers
5649 if needed. Normal server will send JOIN notify to its local client
5650 on same channel when received this packet. Added also corresponding
5651 sending function silc_server_send_new_channel_user to sent the
5654 * Added boolean route argument to send_notif_to_channel and
5655 packet_send_to_channel functions to attempt to route the packet
5656 if it is TRUE and send only locally if it is FALSE.
5658 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * silc_server_replace_id now broadcasts the received replace ID
5661 packet if it is not broadcast packet already. The router must
5662 broadcast to inform other routers about changed ID.
5664 * Added backpointer to server's router into SilcServer context in
5665 silcd/server_internal.h.
5667 * Fixed silc_server_packet_broadcast to send correct broadcast
5670 * The channel key is now distributed to the local client as soon
5671 as it is received from the router (in router environment) so that
5672 no other packet may be sent for the channel until client has
5675 * silc_server_remove_channel_user now broadcasts the received
5676 Remove Channel User packet if it is not broadcast packet already.
5677 The router must broadcast to inform other routers about removed
5680 * Added users field into SilcPacketContext that is a reference count
5681 of the context. One can increase the reference count by calling
5682 silc_packet_context_dup which is now changed to just increase the
5683 reference count instead of duplicating the data. The reference
5684 count is decresed by calling silc_packet_context_free that will
5685 free the data after the reference count hits zero.
5687 For now on the packet context and everything allocated into it
5688 (including the raw packet from network) must be freed by calling
5689 the new silc_packet_context_free function. Added also new function
5690 silc_packet_context_alloc that must be used now to allocate the
5691 context. This also means that if a routine is asynchronous from
5692 silc_[client/server]_packet_parse_type the packet context must
5693 be duplicated by calling silc_packet_context_dup. Otherwise it
5694 gets free'd after silc_[client/server]_packet_parse_type returns.
5695 Also, one must remember that if packet is duplicated then its
5696 reference count must be decresed by calling the free function as
5697 many times as it was duplicated.
5699 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5700 from both client and server.
5702 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Made joining to a channel working in router environment.
5706 * Cleaned up JOIN command on server side and create function
5707 silc_server_command_join_channel internal routine to make the
5710 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Changed silc_command_pending list to SilcDList. Also, added
5713 `ident' field to SilcServerCommandPending structure to identify
5714 the reply and to call correct callback.
5716 Added silc_server_command_pending_check function to replace the
5717 corresnponding macro. The silc_command_pending list is not
5720 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5721 to set identifier to previously allocated Command Payload. It
5722 is used to set identifier for command when resending Command
5725 * Added silc_command_payload_encode_payload to encode Command
5726 Payload buffer from SilcCommandPayload structure.
5728 * Added silc_argument_payload_encode_payload to encode Argument
5729 payload buffer from SilcArgumentPayload structure.
5731 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Changed WHOIS command to support router connection on server side.
5734 The whois request is always sent to router unless the server is
5735 standalone server. After server has received the reply from the
5736 router will it send the reply to the client.
5738 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5739 broadcast received broadcast packet. The function is used only
5740 by router. The broadcast packet is always sent to the router's
5743 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5744 render given ID to printable string, for log files for example.
5746 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Made basic router to router connections working. At least they
5749 can now connect to each other but nothing really works the way
5750 they are supposed - yet.
5752 * Added new initiator token to RouterConnection configuration
5753 file in silcd/serverconfig.[ch]. It is used to tell whether we
5754 are the initiator to the remote router or whether we'll expect
5755 the other end to connect.
5757 * Moved registering of listener task to silc_server_init, hence
5758 the server starts listenning as soon as it is run, even if it
5759 does not have connections to other routers. Let's see how well
5762 * Changed default connection retry timeouts for more suitable in
5765 * Removed cipher and such arguments from silc_idlist_add_client
5766 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5767 Added new function silc_idlist_add_data to add the keys and stuff
5770 * Added SilcIDListData structure and added it to SilcClientEntry
5771 and SilcServerEntry as their first field in the structure. This
5772 way we can explicitly cast the ID entries to the SilcIDListData
5773 structure and get common data for the entries. In past, we had
5774 to first check what type of connection it is and then cast it to
5775 correct ID entry type. Now, we can directly cast the opaque
5776 pointer to the SilcIDListData (no matter what ID entry it actually
5777 is) and get the data needed.
5779 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5782 in some circumstances even if threre were timeout tasks, though not
5783 IO tasks, but tasks anyway. Now fixed.
5785 * Defined SilcServerConnection structure to hold connection specific
5786 stuff about directly connected servers and routers. The definition
5787 is currently in silcd/server_internal.h. I thought about having
5788 a bit more important role fro this struct but for now it is used
5789 only when connecting to other server (or router actually).
5791 * Added connecting retry support in server when connecting to
5792 router(s). The retry feature implement exponential backoff
5793 algorithm. Also, added SilcServerParams structure to hold default
5794 parameters for server. For now, it include these retry settings
5795 and are hard coded. After server is moded to be as Silc Server
5796 Library this structure will be more important.
5798 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Changed client librarys channel->clients table to SilcList and
5801 changed code accordingly.
5803 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Changed client's channel table to SilcList and changed code
5806 accordingly. Also changed SilcChannelClientEntry to include back-
5807 pointer to the channel so that client entry can use that structure
5808 as list as well and we have fast cross-reference to the channel.
5809 This change dramatically decreased the complexity of channel
5810 handling with client entry and vice versa (removed one extra
5811 loop when searching for channel entry from many functions).
5813 * Changed server->sim from table to SilcDList and changed code
5816 * NAMES command can now be used from user interface. It will show
5817 the user list on the channel, neatly.
5819 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5820 Code now saves realname of the user if it becomes available.
5822 * Renamed configure.in to configure.in.pre and made ./prepare
5823 script to automatically add correct version string to
5824 configure.in which it creates from configure.in.pre.
5826 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * NAMES command reply now shows users mode with the nickname when
5831 * Moved silc_client_ch[u]mode[_char] functions from
5832 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5833 place sucks, they are utility functions and should be in some
5836 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5838 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5841 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added TRQ (efficient deque and list library) into lib/trq. This is
5846 a very good list library that is currently used in the SILC. Defined
5847 SilcList API over the library because I didn't like the API very
5848 much. See lib/trq/silclist.h for the API and examples of how to
5849 use the API. Fixed various places in the code to use the new
5850 SilcList API. The SilcList is meant for lists that has a structure
5851 already defined as a list. It is not suitable to add just some
5852 context to the list (in TRQ, the context is the list actually).
5854 So, I defined SilcDList that can be used for the purpose where
5855 predefined list structure does not exit. This can be used as
5856 such list. Now some context just can be added to the SilcDList.
5857 Currently this list is not used in the SILC just yet, though there
5858 are a lot places where this can replace dynamically allocated
5859 tables and I will fix these places, later, to use SilcDList.
5860 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5861 and use TRQ internally).
5863 Also fixed some annoying warning messages that the original TRQ
5864 code generated. Also minor changes to TRQ's Makefile.in.
5866 * Added support for querying by Client ID to both WHOIS and
5867 IDENTIFY commands into server, as required by the protocol.
5869 * Removed method function pointers from SilcBuffer structure. They
5870 weren't used to anything and just increased the context size for
5871 no good reason. This change also made silc_buffer_alloc and
5872 silc_buffer_free functions inline functions.
5874 * Disabled command flooding detection support until it's fixed so
5875 that it accepts commands in but does not execute them more than once
5878 * Added silc_net_localhost(), to return local hostname, into
5879 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5880 that must be initialized before calling silc_client_init.
5882 * Added new function: silc_server_send_notify_on_channels to send
5883 notify messages to all channels client has joined. It is assured
5884 that the message is sent only once per client.
5886 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5887 lib/silcutil/silcutil.[ch] as silc_format function. The new
5888 function is generic and is used by server as well, not only by
5889 the logging routines.
5891 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5892 the provided version string was not acceptable. Added new function:
5893 silc_ske_check_version into lib/silcske/silcske.h. The function
5894 must be implemented by the application (client or server) and it
5895 does not reside in the SKE library. The function checks the version
5896 string remote end sent.
5898 * Added back pointers (to opaque context and to SilcSocketConnection)
5899 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5901 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5902 duplicate packet context structure.
5904 * Changed `notify' client operation to send same arguments as client
5905 receives from server except for ID's. ID's are mapped to correct
5906 ID entry and that is returned. Also, if channel entry is not sent
5907 by server but the notify is for channel the channel entry is sent
5908 to application (otherwise application doesn't know that it is for
5909 channel (library gets it from packet's Destination ID)).
5911 * Added silc_client_remove_from_channels into client library to
5912 remove a client from all channels it has joined to. Used when
5913 received SIGNOFF notify from server. Added also new function
5914 silc_client_replace_from_channels to replace old ID entry with
5915 new ID entry on all channels. Used when received NICK_CHANGE
5918 * Fixed ID Cache list handling in silc_idlist_get_client in
5919 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5920 to get (or query) client by ID.
5922 * Updated TODO list.
5924 * Added connection authentication status message defined by the
5925 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5926 support for these into the code in client and server side.
5928 * Added generic function silc_client_send_command to send any command
5929 with variable argument list. Application should use this function
5930 to send commands if the command functions provided by the library
5931 does not suite for the application's user interface needs.
5933 * Added new `failure' client operation. Application is notified about
5934 received failure packet if client is executing a protocol. In this
5935 case the protocol's execution has failed.
5937 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5938 is required by the protocol.
5940 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5941 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5944 * Added status flag to SilcSKE object to indicate realtime status
5945 of the SKE protocol.
5947 * Application receives now exactly same command reply arguments as
5948 the library receives from server. However, if ID is received the
5949 corresponding ID entry is returned to the application (eg. Client
5950 ID is mapped to correct SilcClientEntry entry and that is returned).
5951 Changed command_reply client operation due to this change.
5953 * Changed all ID's in commands and in command replys as ID Payloads.
5954 Change affected both client and server side codes.
5956 All ID's sent in SILC network (with execption of ID's in SILC
5957 Packet header) are sent in ID Payload to support variable length
5960 * Server now notifies nick changes and notifies all clients on
5961 the channels about the new nickname (about the new Client ID,
5964 * Implemented CMODE command to change channel modes. Supports all
5965 channel modes defined by the protocol specs except ban and invite
5966 lists. (Also, private channel key mode is supported but support for
5967 setting private channel key in client is missing, thus, this mode
5968 has no effect on client side (except that server requires that the
5969 client uses private channel key and normal channel traffic does not
5972 Also, invite mode works per se, but INVITE command does not work
5973 yet correctly, so you can set channel as invite only channel but
5974 inviting clients to the channel does not work (it is yet to be
5975 thought what's the best way to do it).
5977 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5978 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5979 Implemented CUMODE command to change user's mode on the channel.
5980 Supports all modes defined by the protocol specs.
5982 * Added NAMES command reply to return users modes on the channel.
5984 * Removed unnecessary and slow ciphers from lib/silccrypt.
5986 * Set SO_KEEPALIVE option to connection sockets by default.
5988 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5990 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5991 redefined the Notify Payload into protocol specs.
5993 * Added silc_id_payload_parse_id to get ID directly from raw
5996 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5999 accept searching by Client ID as well.
6001 * Added support for LEAVE and SIGNOFF notify types in client library.
6003 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6004 to parse ID Payload from raw data.
6006 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added flags parameter into silc_ske_assemble_security_properties
6009 function in lib/silcske/silcske.[ch].
6011 * Changed notify client operation to fit better for notify messages
6012 sent by server. The notify payload received from server is now
6013 passed to the application (after parsing it to SilcNotifyPayload).
6014 It is application's responsibility to retrieve the arguments
6015 from the payload and show the message the way it wants. The message
6016 sent by server is implementation specific.
6018 * Changed public keys to comply with the protocol specification.
6019 Old public keys are not supported anymore and are not compatible.
6021 * Removed nickname from Channel Payload as the latest draft removed
6022 it. The client must resolve the nickname from the NAMES command
6023 reply received when it joined the channel.
6025 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6027 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Fixed some errors in protocol specification drafts.
6031 * Created lib/silccore/silcnotify.c to implement Notify Payload
6032 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6033 generic payloads described by protocol specifications. The file
6034 includes implementations for ID Payload and Argument Payload.
6036 * Changed Command Payload implementation to use the new Argument
6037 Payload. Changed command_xxxx_payload to command_payload_xxxx
6038 to comply with SILC coding conventions.
6040 * Added suppport for Argument Payload handling in Notify Payload
6041 implementation as protocol requires it. Added the new support
6042 into server and client lib as well.
6044 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added support for multiple nicknames on same channel. [n] is
6047 added locally to the nickname if there are more than one same
6048 nicknames on the channel.
6050 * Server now sends all nicknames that matched WHOIS request.
6051 Client also shows the list received from server.
6053 * Added TOPIC command to client side. User can now set and show
6054 current topic on channel.
6056 * Added MOTD command to client and server. Also, server sends the
6057 motd when client connects to the server.
6059 * Changed version strings to comply ISO 8601.
6061 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Fixed protocol error handling in client library. It should now
6064 cope even if the SKE fails for some reason.
6066 * Made new protocol specification drafts for submitting to IETF.
6068 * Implemented TOPIC command to server in silcd/command.c.
6070 * Added two new notify types into lib/silccore/silcnotify.h:
6071 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6072 notify nickname change and topic setting/change on a channel.
6074 * API change of command_reply operation in client library. The
6075 application gets now the status type received from server as well.
6077 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6081 * Cras fixed and optimized the packet handling even further and
6082 it should work now. Minor change to the prototype of function
6083 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6085 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Added new function into lib/silcutil/silcschedule.[ch]:
6088 silc_schedule_with_fd to select() a specified fd. The function
6089 returns after timeout expires or data arrives or goes. The
6090 function is used by packet routines to wait that all data is
6091 received from network.
6093 * Fixed data reading from network in lib/silccore/silcpacket.c.
6094 The code now assures that all data is read from the fd and then
6095 continues packet processing. This was a bug fix since the code
6096 used to drop some data in some circumstances.
6098 * Added new function into lib/silcclient/client.[ch]:
6099 silc_client_start_key_exchange to start key exchange after
6100 connection has been established to server. The code internally
6101 now uses this funtion but its main purpose was to provide it
6102 for applications that perform their own connecting. After
6103 application has created a connection it merely calls this
6104 function to start the key exchange between client and server.
6105 The library takes care of everything else after that.
6107 Updated also lib/silcclient/README to explain the usage of
6110 * Do not send to application information that connection has
6111 been established. Application gets notified it by connect
6114 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Applied cras's patch to add silc_schedule_one function. The
6117 function runs scheduler once and returns.
6119 * Fixed the scheduler after cras messed it up. The timeout
6120 handling works now as it's supposed to work.
6122 * Added into lib/silccore/ silcnotify.h to include notify
6123 message types support. Changed silc_server_send_notify*
6124 functions, in server.[ch], to support those new notify types.
6125 Added the support for the notify types into client library,
6126 as well. Added new notify client operation into ops.h in
6129 * Changed silc_server_packet_send_to_channel to send normal
6130 packets instead of just channel message packets. The function
6131 is now used to send the notify packets to channels. It is not
6132 used to send channel message packets anymore, as server never
6135 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6136 va_arg()s as it seems to require it nowadays. I guess, if SILC
6137 is compiled with older va_arg() the new code should work anyway.
6139 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Splitted core library. Core library (lib/silccore) includes
6142 now only SILC protocol specific core (and common) components.
6143 Created new utility library (lib/silcutil) that includes more
6144 generic purpose stuff. The stuff for util library was taken
6145 from the old core library. This was minor and easy split.
6147 * Created SILC Client Library (lib/silcclient) that includes
6148 implementation of the SILC client without user interface. This
6149 was major move from silc/ directory. The code has been changed
6150 so that it is transparent towards the user interface. The
6151 silc/ directory includes now the same user interface as before
6152 and it uses the new client library. Read lib/silcclient/README.
6153 Basicly, the client library performs everything else related
6154 to SILC except user interface handling. Also, configuration
6155 files are considered to be part of user interface and library
6156 does not handle them.
6158 This change also changed a lot of structures, function naming etc.
6159 Most important change was that SilcClientWindow object was
6160 renamed to SilcClientConnection in the client library. Created
6161 also new file lib/silcclient/ops.h. Also added new files
6162 silc/local_command.[ch] and silc/client_ops.[ch].
6164 All these changes were made to make it easier for user interface
6165 designers to create what ever user interface for the SILC client
6168 It is also expected that the server will be moved to lib
6169 directory as well and SILC Server Library will be created;
6170 sometimes in the future.
6172 * Removed Local commands from lib/silccore/silccommand.h as
6173 they are application specific and new client library does not
6174 handle any of those anymore.
6176 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6177 old client implementation in silc/.
6179 * Added support for callback functions in SILC_LOG_* macros.
6180 Application can now set its own callbacks that will be called
6181 instead of using the default functions that will always print
6182 the debug messages to stderr (or stdout). Also, debugging can
6183 now be disabled by setting silc_debug to FALSE and re-enabled by
6184 setting it to TRUE. Note, that logging will still work even
6185 if debugging is disabled.
6187 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6188 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6189 silc_log_reset_debug_callbacks.
6191 * To enable debugging in silc client one must give now -d
6192 option on command line.
6194 * Changed silc_schedule_init to automatically allocate task queues
6195 if they are not allocated before calling it.
6197 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Added GMP 3.1 into math library.
6201 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6204 a channel in SILC network. The packet is used by servers and
6205 routers to notify other routers that user has left a channel.
6206 This little feature was missing until now. Added the feature
6207 to protocol specification as well.
6209 Added functions: silc_server_send_remove_channel_user and
6210 silc_server_remove_channel_user into server.[ch].
6212 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6213 lib/silccore/silcpacket.h. However, they are not implemented
6216 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Fixed joining to a channel and sending channel messages
6219 between server and router. The channel message sending should
6220 now work inside a cell.
6222 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Fixed the private message sending between server and router.
6225 The private message sending should now work inside a cell.
6227 * Added silc_server_replace_id into server.[ch] to replace
6228 existing ID in the SILC network.
6230 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6231 and silc_idlist_replace_server_id into idlist.[ch] in server.
6233 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Fixed the server to server connections. Server can again now
6236 connect to router. Router to router connections probably does
6239 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Added dynamic protocol registering support. Now protocols can
6242 registered and unregistered on the fly. Patch by cras.
6244 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added lib/contrib directory to hold routines that some platforms
6247 don't have but are needed by SILC.
6249 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6250 into lin/contrib to provide getopt() and getopt_long() for
6251 those who don't have it.
6253 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Added AWAY command to client. When away message is set and
6256 client receives a private message packet the client automatically
6257 replies to the sender with the away message.
6259 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6260 bug seemed to be the cause of recent problems when compiling
6263 * Added version detection support to SKE protocol specification
6264 and added the new changes to the SKE implementation as well.
6265 There were other minor changes in the SKE protocol as well.
6267 Many changes in lib/silcske/silcske.[ch] and in
6268 lib/silcske/payload.[ch].
6270 * Added ^U functionality, clear input line. Patch from cras.
6272 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Mainly small bugfixes on core library. Fixed some debugging
6275 logging and buffer overflow in silclog.c.
6277 * Updated config.sub and config.guess on the distribution tree.
6279 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Added command lagging support in server. Client may execute
6282 commands now only once in two seconds.
6284 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Optimized packet reception. MAC computation and checking is now
6287 also more optimized. A lot previously duplicated code is now
6288 used as generic by both client and server.
6290 * Fixed key pair generation in clientutil.c
6292 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6294 * Added into lib/silccore/silcbufutil.[ch] new function;
6295 silc_buffer_realloc.
6297 * Moved generic packet sending/encryption functions to
6298 lib/silccore/silcpacket.[ch] from client and server. Some
6299 rewriting of the functions.
6301 * Moved all generic packet reception/decryption functions to
6302 lib/silccore/silcpacket.[ch] from client and server. The
6303 packet processing is now much cleaner in both client and server.
6304 These were major changes in both client and server.
6306 * Created many common functions in server to do packet sending.
6307 Previously code were duplicated a lot, this has been removed
6310 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Rewrote major parts of the ID cache system. Don't know
6313 whether it is better now or not but at least the API is more
6316 * Major rewrite on ID cache stuff on client because of the ID
6317 cache API changes. Added idlist.c to client.
6319 * Also major rewrite on ID cache stuff on server as well.
6320 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6321 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6322 in hand, instead they are all put into the ID cache system now.
6323 All server_idlist_* routines uses ID cache now instead of
6324 traversing its own lists (those lists does not exist anymore).
6325 SilcIDList though still exists. Also, SilcXXXEntry's are
6328 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Finally made the SKE implementation compliant to the protocol
6331 specification. All mp integers are now binary encoded as
6332 opposed being HEX encoded.
6334 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6337 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6338 functions: silc_[encode/decode]_pem. Also added function
6339 silc_encode_pem_file to PEM encode with newlines ('\n') for
6342 * SILC public keys are now encoded either PEM or binary. Same
6343 option is for private keys as well. By default private keys
6344 are binary encoded and public keys PEM encoded. Silly HEX
6345 encoding were removed.
6347 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6348 function to create fingerprints.
6350 * Fixed a bug in SHA1; does not change the original data anymore.
6352 * Partly implemented INFO command on client and server side.
6353 Fixed CLEAR command. Changes to SERVER command; show current
6354 server(s) when giving command without arguments. Added
6355 VERSION command to client.
6357 * Added check to server that unregistered connections cannot
6358 execute commands (unless it is specificly allowed).
6360 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Fixed screen refresh.
6364 * Fixed channel joining bug from client. On some circumstances
6365 client tried to join to a channel it had already joined.
6367 * Added public key verification process into client's protocol.c.
6368 The client now verifies the public key from user and saves
6369 it into ~./silc/serverkeys/ directory.
6371 Added into: clientutil.[ch]: silc_client_verify_server_key.
6373 * Changed SKE protocol's silc_ske_initiator_finish function
6374 to accept callback function that verifies the received public
6375 key. Removed old silc_ske_verify_public_key function.
6377 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6380 silc_pkcs_private_key[_data]_set.
6382 * Made the password and public authentication more cleaner in
6383 server's protocol.c.
6385 * Removed historic and obsolete protocol `channel_auth' from
6386 both client and server.
6388 * Removed wrong way of sending command status messages from
6389 server to client in server's command.c. The old way violated
6390 protocol specification.
6392 Changes to silccore/silccommand.[ch]: removed
6393 silc_command_encode_status_payload -> not needed anymore,
6394 changed silc_command_encode_payload_va to accept extra
6395 argument on variable argument list. The argument type must
6396 now be provided to the function. Also, added new function:
6397 silc_command_encode_reply_payload_va which is same as
6398 normal command_encode_payload_va except command status type
6399 is provided as extra argument.
6401 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added ~./silc directory handling. The directory includes the
6404 public and private keys for the client.
6406 Added silc_client_check_silc_dir, silc_client_create_identifier
6407 and silc_client_load_keys.
6409 * Implemented SILC protocol compliant public key. Added public
6410 and private key saving to and loading from files.
6412 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6413 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6414 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6415 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6416 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6418 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6419 silc_pkcs_load_[public/private]_key.
6421 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Added silc_server_get_route (route.[ch]) to get connection
6424 data for the fastest route for given ID.
6426 * Implemented INVITE command on client and server. The command
6427 were re-defined in the SILC Protocol Specification and the
6428 implementation now complies with the specification.
6430 * Implemented PING command on client and server.
6432 * Implemented NAMES command on client and server. The server side
6433 supports currently only normal server not router server yet.
6434 Some changes to NAMES definition in SILC protocol specification.
6436 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6438 * Implemented LEAVE command on client and server.
6440 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6441 again. This change was made to the protocol as well. Server
6442 should not violate the protocol specification anymore.
6444 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6447 was tested. SOCKS4 was not but should work anyway.
