1 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * If first character of string in silc_parse_userfqdn is '@'
4 then do not parse it. Affected file is
5 lib/silcutil/silcutil.c.
7 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Fixed minor bug in IDENTIFY command reply sending, which
10 caused various weird problems during JOIN when it was
11 resolving names for users. Affected file silcd/command.c.
13 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
15 * Fixed the IDENTIFY command reply sending to chech better valid
16 clients. It was possible to send incomplete list of replies.
17 Affected file silcd/command.c.
19 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
21 * Added silc_client_command[s]_[un]register functions now to
22 dynamically register the commands in client library. Removed
23 the static table of commands. This allows the client library
24 to call commands without causing the application to know about
25 what commands library has called.
27 Removed the INFO command reply kludge to detect when the command
28 was called by library. Now library use its own command reply
29 function for INFO command.
31 Added function silc_client_command_call to call a command.
32 Application can use it to call command, not access the structure
35 Now all commands that are sent by the client library (not
36 explicitly sent by application) use own command reply functions.
38 Affected files around lib/silcclient/ and in
41 * Fixed the WHOIS command reply sending to chech better valid
42 clients. It was possible to send incomplete list of replies.
44 Fixed the WHOIS and IDENTIFY to send the request to router
45 if normal server did not do it and did not find any results.
47 Affected file silcd/command.c.
49 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
51 * Moved the internal data from SilcClient context into its
52 own file, not accesible to application. Affected files
53 lib/silcclient/client.h and lib/silcclient/client_internal.h,
54 and other files in client library.
56 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
58 * Added doc/examples installation target in Makefile.am.pre.
61 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
63 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
64 commands the found client entry will be removed from the
65 cache, after notifying application about the error. Affected
66 file lib/silcclient/command_reply.c.
68 * Changed the /MSG to check for exact nickname user gave, and
69 not let `nick' match `nick@host' if it is only one found. Now,
70 user must type the exact nickname (like nick@host2) even if
71 there are no more than one same nicks found. This is to avoid
72 a possibility of sending nickname to wrong nickname since
73 `nick' could match `nick@host'. Affected file is
74 irssi/src/core/silc-servers.c.
76 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
78 * Do not print "you are now server operator" or similar when
79 giving /away command. Affected files are
80 irssi/src/silc/core/client_ops.c, silc-servers.h.
82 * Made the silc_server_command_pending_error_check to send
83 the same command reply payload it received back to the
84 original sender of the command. This way all arguments
85 that was received by the server will be received by the
86 client too. Affected file silcd/command.c.
88 * Added the silc_idcache_add to return the created cache entry
89 to a pointer. Affected file lib/silccore/silcidcache.[ch].
91 * Add global clients to expire if they are not on any channel.
92 This is because normal server will never know if they signoff
93 if they are not on any channel. The cache expiry will take
94 case of these entries. This is done by normal servers only.
95 The affected files are silcd/command_reply.c,
96 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
98 * If server receives invalid ID notification for WHOIS or
99 IDENTIFY and the ID exists in the lists, it is removed.
100 Affected file silcd/command_reply.c.
102 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
103 in client then client entry that it matches is searched and
104 the nickname is printed on the screen for user. Affected
105 file irssi/src/silc/core/client_ops.c.
107 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
109 * Use cache entry expire time in the LIST command reply to
110 purge old entries from the cache after the LIST command
111 reply has been received. This way we don't have non-existent
112 entries in the cache for too long. Affected file is
113 silcd/command_reply.c.
115 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
117 * If we are normal server, and we've not resolved client info
118 in WHOIS or IDENTIFY from router, and it is global client,
119 we'll check whether it is on some channel. If it is not
120 then we cannot be sure about its validity and will resolve it
121 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
122 file silcd/command.c.
124 * Search channel by name (if possible) rather than by ID
125 in IDENTIFY command's command reply. Affected file is
126 silcd/command_reply.c.
128 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Distribute to the channel passphrase in CMODE_CHANGE notify.
131 Updated specs and implemented it. Affected file silcd/command.c,
132 silcd/packet_send.c and silcd/packet_receive.c.
134 * Implemented the <founder auth> payload handling in the JOIN
135 command. If provided all conditions for channel joining
136 except requirement to provide correct passphrase can be
137 overrided by the channel founder. Updated the protocol specs.
138 Affected file silcd/command.c.
140 Added support for founder auth in JOIN command in client
141 library. Fixed the parsing of the JOIN command now to support
142 all options as they should be. The affected file is
143 lib/silcclient/command.c.
145 * Optimized the WHOIS and IDENTIFY commands to send the request
146 to router only if it includes nicknames or other names. If
147 they include only IDs then check the local cache first before
148 routing. Affected file is silcd/command.c.
150 * Added channels topic announcements. Affected file is
151 silcd/packet_receive.c and silcd/server.c.
153 * Fixed the silc_server_send_notify_topic_set to really destine
154 the packet to channel. Affected file silcd/packet_send.c.
156 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
157 library. Affected file lib/silcclient/client_notify.c.
159 * Added UMODE announcements. Affected file silcd/server.c.
161 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
163 * Memory leak fixes in:
165 lib/silcutil/silcsockconn.c
166 lib/silcske/silcske.c
169 lib/silccrypt/silcpkcs.c
170 lib/silccore/silccommand.c
171 lib/silccore/silcidcache.c
176 * ROBOdoc documented the lib/silcske/groups.h file and a
177 bit changed the interface for better.
179 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
181 * Update the client entry context in the ID cache after
182 nick change. Affected file lib/silcclient/command.c.
183 Fixes the CUMODE command when regaining founder privileges,
184 and a little WHOIS problem.
186 * Fixed silc_net_gethostbyname to correctly call the
187 inet_ntop. Affected file lib/silcutil/silcnet.c.
189 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
191 * Added IPv6 support checking to the configure.in.pre, added
192 also --enable-ipv6 option to override the check. Affected
193 file configure.in.pre.
195 * The silc_thread_create now calls the start function
196 directly if threads support is not compiled in. Removes
197 ugly #ifdef's from generic code. Affected files are
198 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
200 * Added silc_net_gethostby[name/addr]_async to asynchronously
201 resolve. Affected files are lib/silcutil/silcnet.[ch].
203 * Added support for rendering IPv6 based server, client and
204 channel IDs. Affected file lib/silcutil/silcutil.c.
206 * Added support for creating IPv6 based server IDs. Affected
207 file is silcd/serverid.c.
209 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
211 * Added silc_net_gethostby[addr/name] into the
212 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
213 routines. Added silc_net_is_ip[4/6]. Affected file is
214 lib/silcutil/unix/silcunixnet.c. All routines that take
215 address as argument now supports both IPv4 and IPv6 addresses.
217 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
219 * Fixed LIST command reply sending in server. Affected file
222 * Server now sends the kicker's client ID in the KICK notify
223 to the kicked client. Affected file silcd/command.c.
225 * The client library now parses the kickers client ID and
226 UI displays it. Affected files lib/silcclient/client_notify.c
227 and irssi/src/silc/core/silc-channels.c, module-formats.c.
229 * Made all payload parsing function prototypes consistent.
230 They all take now const unsigned char * and uint32 pair as
231 the payload data instead of SilcBuffer. Changes all around
232 the source tree. Other unsigned char* -> const unsigned char*
233 changes around the tree as well.
235 * Optimized SFTP client and server packet sending not to
236 allocate new buffer for each packet but to recycle the
237 first allocated buffer. Affected files are
238 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
240 * Optimized the SFTP client to use SilcList instead of
241 SilcDList for requests, because it is faster. Affected file
242 is lib/silcsftp/sftp_client.c.
244 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
245 into lib/silccore/silcid.[ch].
247 Renamed silcpayload.[ch] into silcargument.[ch].
249 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
251 * If client entry is deleted with active key agreement
252 session, abort the session.
254 The silc_client_abort_key_agreement now calls the completion
255 callback with new SILC_KEY_AGREEMENT_ABORTED status.
257 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
260 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Don't use __restrict in older GCC's. Affected file is
263 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
265 * silc_net_localhost now attempts to reverse lookup the
266 IP/hostname. Affected file lib/silcutil/silcnet.c.
268 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
269 command. It can be used to gain founder privileges at
270 the same time when joining the channel.
272 Defined that the SILC_NOTIFY_TYPE_KICKED send the
273 kicker's client ID as well. Updated protocol specs.
275 Defined that the server must send SILC_COMMAND_IDENTIFY
276 command reply with error status to client who sent
277 private message with invalid client ID.
279 Updated the protocol specification.
281 * Added silc_server_send_command_reply to send any
282 command reply. Affected file silcd/packet_send.[ch].
284 * Added silc_id_payload_encode_data to encode ID payload
285 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
287 * The server now send IDENTIFY command reply with error
288 status if client ID in private message is invalid. Affected
289 file silcd/packet_receive.c.
291 * Save the server key file with server's IP address in
292 the filename instead of hostname. The affected file is
293 irssi/src/silc/core/client_ops.c.
295 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
297 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
300 * Added libtool support for compiling shared objects in
301 lib/silcsim. Affected file configure.in.pre and
302 lib/silcsim/Makefile.am. Original patch by cras.
304 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
306 * Pid file configuration, and server's config file fixes
307 patch by toma. Updated CREDITS file.
309 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
311 * Fixed silc_client_channel_message to not try to decrypt
312 the message twice if it resolved the destination client
313 information. This could cause of dropping one channel
314 message. Affected file lib/silcclient/client_channel.c.
316 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Added silc_client_run_one into lib/silcclient/silcapi.h and
319 lib/silcclient/client.c. This function is used when the SILC
320 Client is run under some other scheduler, or event loop or
321 main loop. On GUI applications, for example this may be
322 desired to used to run the client under the GUI application's
323 main loop. Typically the GUI application would register an
324 idle task that calls this function multiple times in a second
325 to quickly process the SILC specific data.
327 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
329 * Fixed silc_server_drop() for dropping the supplementary
330 groups as well, this could cause a security hole on some
333 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
335 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
338 * Write PID file after dropping privileges. Added -F option
339 to run server on foreground. A patch by debolaz.
340 Affected files silcd/server.c, silcd/silcd.c.
342 * Fixed MOTD to return the MOTD file server name. Affected
343 file silcd/command.c.
345 * Added INFO command reply handling to the Irssi SILC Client.
346 Affected file irssi/src/silc/core/client_ops.c.
348 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
350 * Fixed the silc_idcache_list_* routines to really support
351 the dynamic list. Fixes a crash. Affected file is
352 lib/silccore/silcidcache.c.
354 * Fixed the LIST command reply to really call LIST command's
355 pending callbacks. Affected file silcd/command_reply.c.
357 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
359 * Update conn->local_entry->nickname after giving NICK
360 command. Affected file lib/silcclient/command.c.
362 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
364 * Added the [pid] option to the silcd configuration file
366 Affected files: serverconfig.[ch] and silcd.c
368 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
370 * Save fingerprint in WHOIS command reply in server.
371 Affected file silcd/command_reply.c.
373 * Fixed NICK commands pending callback registration.
374 Affected file lib/silcclient/command.c.
376 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Use ++server->cmd_ident when sending commands in server,
379 instead of random number. Affected file silcd/command.c.
381 * Fixed GETKEY command reply to call actually GETKEY pending
382 command callbacks. Affected file silcd/command_reply.c.
384 * A bit stricter check for nicknames. Check for same nickname
385 in NICK command also. Affected file silcd/command.c.
387 * Do not call INFO command everytime client ID changes, only
388 during first connecting. Affected file lib/silcclient/client.c.
390 * Set the new nickname only after successful command reply for
391 NICK command is returned by server. Affected file
392 lib/silcclient/command.c.
394 * Remove nicknames from nicklist during server_signoff notify.
395 Should fix /NAMES bit more. The affected file is
396 irssi/src/silc/core/silc-channels.c.
398 * Added `fingerprint' field to the SilcIDListData in the
399 silcd/idlist.h to hold the fingerprint of the client's
402 Send the fingerprint of the client's public key in WHOIS
405 Affected files silcd/command.c, and silcd/idlist.[ch].
407 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
408 create fingerprint from given data.
410 * Show the fingerprint of the client's public key in WHOIS.
411 Affected files irssi/src/module-formats.[ch] and
412 irssi/src/silc/core/client_ops.c.
414 * Format the multiple same nicknames also during JOIN and
415 NICK_CHANGE notifys. Affected file is
416 lib/silcclient/client_notify.c.
418 * Do not print error on screen for invalid private message
419 payload since it can come if someone is sending private
420 messages with wrong key. Affected file
421 lib/silccore/silcprivate.c.
423 * Fixed multiple concurrent /PING crash. Affected file
424 lib/silcclient/command.c.
426 * Changed the wrong ID encoding. All IP addresses must be
427 in MSB first order in encoded format. They were encoded
428 wrong and was in LSB format. Affected files are
429 silcd/serverid.c, lib/silcutil/silcutil.c.
431 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
433 * Call the `connect' client operation through the scheduler
434 in case of error. Affected file lib/silcclient/client.c.
436 * Call the `failure' client operation even if the error
437 occurred locally during a protocol. Affected file is
438 lib/silcclient/protocol.c.
440 * Added support of sending LIST command to router from normal
441 server. This way normal server can get list of all channels
442 in the network too. Fixed the channel list sending in the
443 server too. Affected files are silcd/command.c, and
444 silcd/command_reply.[ch].
446 * Added silc_server_update_channels_by_server and
447 silc_server_remove_channels_by_server. They are used during
448 disconnection of primary router and in backup router protocol.
449 Affected file silcd/server_util.[ch], silcd/server.c and
450 silcd/server_backup.c.
452 * Fixed channel adding to global list in IDENTIFY command
453 reply in server. Affected file silcd/command_reply.c.
455 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
457 * If the incoming packet type is REKEY or REKEY_DONE process
458 that packet always synchronously. Fixes yet another MAC
459 failed error on slow (dialup) connections. Affected file
460 lib/silcclient/client.c and silcd/server.c.
462 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
464 * Call check_version SKE callback for initiator too. Affected
465 file lib/silcske/silcske.c.
467 * Implemented fix for security hole found in the SKE that was
468 fixed in the specification few days back; the initiator's
469 public key is now added to the HASH value computation.
470 Added backwards support for the old way of doing it too, for
471 old clients and old servers. Affected file is
472 lib/silcske/silcske.c.
474 * Enabled mutual authentication by default in SKE. If initiator
475 is not providing mutual authentication the responder will
476 force it. This will provide the proof of posession of the
477 private key for responder. The affected files are
478 lib/silcclient/protocol.c and silcd/protocol.c.
480 * Do not cache anymore the server's public key during SKE.
481 We do mutual authentication so the proof of posession of
482 private key is done, and if the server is authenticated in
483 conn auth protocol with public key we must have the public
484 key already. Affected file silcd/protocol.c.
486 * Added new global debug variable: silc_debug_hexdump. If
487 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
488 file lib/silcutil/silclog.[ch].
490 * Fixed compilation warning due to char * -> const char *.
491 Affected files lib/silcutil/silcnet.h, and
492 lib/silccore/silcauth.[ch].
494 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Fixed CMODE command when new channel key was created. If
497 the creation failed the old key was removed. Next time giving
498 same command would crash the server since the old key was
499 freed already. Affected file silcd/command.c.
501 * Fixed the silc_server_announce_get_channels to not crash
502 on reconnect. Affected file silcd/server.c.
504 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
506 * Added silc_log_set_debug_string function to set a regex
507 string to match for debug output. Only the function names,
508 or filenames matching the given debug string is actually
509 printed. This way it is possible to filter out those debug
510 strings that user is not interested in.
512 Fixed a bug in silc_string_regexify.
514 Affected files lib/silcutil/silclog.[ch], and
515 lib/silcutil/unix/silcunixutil.c.
517 * Changed the -d options in both server and Irssi SILC client
518 to take the debug string as argument. Affected files
519 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
521 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
523 * Added silc_hash_babbleprint to create a Bubble Babble
524 Encoded fingerprint. The encoding is developed by Antti
525 Huima (draft-huima-babble-01.txt), and it creates human
526 readable strings out of binary data. Affected file
527 lib/silccrypt/silchash.[ch].
529 * Print the babble print now in addition of fingerprint as well
530 in Irssi SILC client. Affected files are
531 irssi/src/fe-common/silc/module-formats.[ch],
532 irssi/src/fe-common/silc/core/client_ops.c.
534 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Fixed a security problem found in SKE. The initiator's
537 public key too is now added to the HASH hash value creation
538 which is signed by the responder to create the SIGN value.
539 This will prevent anyone in the middle to lie to the responder
540 about the initiator's public key. If this is done now, the
541 man in the middle will get caught. Updated the protocol
544 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
546 * Better installation directory handling. Configure module
547 paths and other paths automatically to example_silc* files
548 in doc/. A patch by toma.
550 * Fixed compiler warning from MPI library, and from SILC RNG.
553 * Added SILC_SERVER_PID_FILE to define the pid file for server.
554 It can be configured with ./configure. A patch by toma.
556 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
558 * Find correct make to use in prepare-clean. A patch by
559 toma. Affected file prepare-clean.
561 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
563 * Added irssi variables use_auto_addr, auto_bind_ip,
564 auto_bind_port and auto_public_ip.
566 * Changed the interface for silc_client_send_key_agreement
567 in lib/silcclient/silcapi.h

578 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
580 * Added silc_pkcs_public_key_compare to compare two
581 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
583 * Check that the client who set the founder mode on the
584 channel is the same client that is giving the founder
585 mode to itself. It is done by comparing the saved public
586 key (it is saved even in the authentication is passphrase).
587 Affected file silcd/command.c.

597 * Fixed the silc_client_packet_parse to not to increase
598 the packet sequence number if the conn->sock and the
599 current socket connection is not same. This can happen
600 for example during key agreement when the conn includes
601 multiple socket connections (listeners). Affected file
602 lib/silcclient/client.c.
604 * The sender of the file transfer request now provides also
605 the pointer (listener) for the key exchange protocol. If
606 the listener cannot be created then it sends empty key
607 agreement and lets the receiver provide the listener.
609 Added `local_ip' and `local_port' arguments to the
610 silc_client_file_send. If they are provided they are used,
611 if not then it will attempt to find local IP address, if
612 not found or bind fails then the remote client will provide
615 Affected files are lib/silcclient/client_ftp.c and
616 lib/silcclient/silcapi.h.

625 of the client's public key (if the proof of posession of the
626 corresponding private key is verified by the server).
627 Updated to the protocol specification.
629 * Added support of receiving the client's public key's
630 fingerprint in command reply in client library. Affected
631 file is lib/silcclient/command_reply.c, and

690 during SERVER_SIGNOFF, but invalidate it. This way we
691 preserve the WHOWAS info for the client. Affected file
694 * Fixed SERVER_SIGNOFF notify handling in the server. The
695 server is now able to process incoming SERVER_SIGNOFF notify
696 for a server that it doesn't even know about. It will remove
697 the clients provided in the notify. Affected file
698 silcd/packet_receive.c.
700 * Check for partial packet in data queue after every packet that
701 was found from the queue. Return and wait for more data if

727 available. It is used in padding generation. Affected file
728 lib/silccrypt/silcrng.[ch].
730 * All packets in client library are now processed synchronously.
731 Optimized packet processing a lot. Affected file
732 lib/silcclient/client.c.
734 * All server connection packets are processing synchronously
735 now in server, to optimize packet processing. Affected file
738 * Include files are installed now only in Toolkit distribution
739 if make install is given. Affected files: all Makefile.am's.
741 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Assure that silc_client_notify_by_server_resolve does not
744 resolve the client information multiple times. If it cannot
745 be found by the first it cannot be found at all. Affected
746 file lib/silcclient/client_notify.c.
748 * Fixed WHOWAS command reply calling. Affected file
749 lib/silcclient/command_reply.c.
751 * Removed all references to silc_idlist_get_client from the
752 Irssi SILC client since that call is internal call used by
753 the library. The Irssi SILC client will use now client
754 retrieval functions found in silcapi.h.
756 * Fixed a bug in resolving nickname info before sending
757 private message. It used freed memory. Affected file
758 irssi/src/silc/core/silc-servers.c.
760 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

784 in packet queue that we are not able to process without first
785 processing packets before them. Affected file silcd/server,
786 lib/silcclient/client.c.
788 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
789 whether library should continue processing the packet.

873 * Redefined the SILC packet header to include the padding
874 length. Affected file lib/silccore/silcpacket.[ch].
876 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
877 length for maximum padding up to 128 bytes). Affected
878 file lib/silccore/silcpacket.h.
880 * Removed all backwards support for old 0.5.x MAC thingies.
881 The SILC packet header change makes it impossible to be
882 backwards compatible.
884 * Send the ENDING packet with timeout in the backup resuming
885 protocol. This is to assure that all routers has connected
886 to the primary router. Affected file silcd/server_backup.c.
888 * Changed the RNG to take the first IV from random data. It
889 used to take it from zero actually. Changed the RNG also
890 to use /dev/urandom during session. /dev/random is used
891 in initialization. Affected file lib/silccrypt/silcrng.[ch].

896 (the packet length) encrypted. Affected files aroung the
897 code tree, lib/silccore/silcpacket.[ch]. Removed the
898 SilcPacketCheckDecrypt callback. It is not needed anymore
899 since the silc_packet_receive_process will determine now
900 whether the packet is normal or special.
902 * Implemented the unidirectional MAC keys. Affected files
903 lib/silcske/silcske.c, silcd/protocol.c and
904 lib/silcclient/protocol.c.
906 * Implemented the packet sequence number to the MAC computation.

911 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
913 * Allow backup router to announce servers. All servers
914 announced by backup router are added to the global list
915 automatically. Update hte server's socket to our primary
916 router also when backup router announces a server.
917 Affected file silcd/packet_receive.c.
919 * Do not update the client->router in the function
920 silc_server_udpate_clients_by_server if the client is on
921 global list. We might fail to find any specific server
922 for locally connected clients and local cell clients. They
923 should still use the `from' and not `to' as client->router.
924 This fixes backup router resuming protocol. Affected file
927 * Decrease channel statistics count only if the channel
928 deletion worked. Affected files are silcd/server.c and
931 * Added silc_server_update_servers_by_server to update origin
932 of all server entries. Used during backup router protocol.
933 Affected files silcd/server_util.[ch], silcd/server.c. and

967 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
968 Affected file silcd/packet_send.c.
970 * Changed the SFTP Filesystem interface. Changed the
971 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
972 the filesystem operation function. The SilcSFTPFilesystem
973 is now a context that is allocated by all filesystem allocation
974 functions and it already includes the operations structure
975 and filesystem specific context. It is given as argument
976 now to the silc_sftp_server_start. This made the interface
977 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
978 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
980 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Changed the backup router adding and getting interfaces
983 in the server. The router that will be replaced by the
984 specified backup router is now sent as argument. Affected

1045 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1046 in the server to indicate disabled entry. All data read
1047 from the connection will be ignored and no data is sent
1048 for entry that is disabled. Affected files are
1049 silcd/idlist.h, silcd/server.c.
1051 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Created SFTP client and server test programs in the

1109 the position as primary router.
1111 * Redefined the MAC generation keys in the protocol. The
1112 same key is not used anymore in both direction. Both
1113 direction will now use different keys for sending and
1114 receiving. This fixes a potential security flaw. This
1115 change causes incompatibilities in the protocol.
1117 * Redefined also the MAC computation from the packet.
1118 An packet sequence number is now added to the MAC
1119 computation. This prevents possible replay attacks against
1120 the protocol. This change too causes incompatibilities
1123 Added `sequence' field to the SilcPacketContext to hold
1124 the current sequence number for the packet.
1126 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Added `created' field to the SilcIDListData in the file
1129 silcd/idlist.h to indicate the time when the entry was
1132 * Added `created' field to the SilcChannelEntry too. Affected
1133 file silcd/idlist.h.
1135 * Added `creation_time' aguments to all the announcement functions
1136 in the server. If it is provided then only the entries that
1137 was created after the provided time frame are actually
1138 announced. Affected file silcd/server.[ch].
1140 * The protocol says that the Channel ID's IP address must be
1141 based on the router's IP address. Added check for this in
1142 the silc_server_new_channel when processing incoming New Channel
1143 Payload. Affected file silcd/packet_receive.c.
1145 * Print out the correct version with --version in SILC client.
1146 Affected file irssi/src/silc/core/silc-core.c.
1148 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * Fixed WHOWAS command to check for completnes of the client
1151 entry always, not just when the command is coming from client.
1152 Affected file silcd/command.c.
1154 * Added new function silc_server_packet_queue_purge to purge the
1155 outgoing data queue to the network. After the function returns
1156 it is guaranteed that the outgoing packet queue is empty.
1157 Affected file silcd/packet_send.[ch].
1159 * Purge the outgoing packet queue in the rekey protocol's final
1160 callback to assure that all rekey packets go to the network
1161 before quitting the protocol. Affected file silcd/server.c.
1163 * Added silc_client_packet_queue_parse as similar function as
1164 in server to the client library. The affected file is
1165 lib/silcclient/client.c.
1167 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1169 * Splitted silcd/server.c and created silcd/server_util.[ch]
1170 for utility functions.
1172 * Added new socket flag SILC_SF_DISABLED to indicate that the
1173 connection is open but nothing can be sent to or received from
1174 the connection. Affected file lib/silcutil/silsockconn.[ch].
1175 The checking for disabled socket is checked in the low level
1176 silc_socket_write and silc_socket_read functions.
1178 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Allow only nicknames and channel names that fits into the
1181 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1183 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * When processing JOIN command reply in server check that if
1186 the channel exists in our global list we'll move it the local
1187 list. Affected file silcd/command_reply.c.
1189 * Fixed the check whether client is joined on the channel already
1190 in JOIN command. Affected file lib/silcclient/command.c.
1192 * Fixed the JOIN command reply to check whether the channel
1193 already exists. Affected file lib/silcclient/command_reply.c.
1195 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Added silc_ske_status_string to map the SKE error numbers
1198 to readable strings. The affected files are
1199 lib/silcske/silcske[_status].[ch].
1201 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Do not show the private channels on the WHOIS channel list
1204 as it is not allowed by the protocol. The affected file is
1207 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Assure that the packet length digged from the actual packet
1210 is something sensible in the silc_packet_decrypt_rest_special
1211 in lib/silccrypt/silcpacket.c.
1213 * Free and NULL the allocated pointer in silc_hmac_alloc if
1214 the HMAC allocation fails. The affected file is
1215 lib/silccrypt/silchmac.c.
1217 * Print the selected security properties to the log files in
1218 the server. Affected file silcd/protocol.c.
1220 * Add SKE's reference counter even if calling the completion
1221 callback manually. Otherwise it goes negative, although it
1222 does not cause any problems. The affected file is
1223 lib/silcske/silcske.c.
1225 * Remove the client entry with short timeout after giving the
1226 KILL command. Affected file lib/silcclient/command.c.
1228 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1229 case all found clients are already disconnected (WHOWAS would
1230 found them) in the server. Affected file silcd/command.c.
1232 * Update the last_receive (time of last data received) to be
1233 updated only when received private or channel message so that
1234 the idle time showed in WHOIS makes more sense.
1236 * Added boolean field `valid' in to the SilcClientEntry in the
1237 client library to indicate whether the entry is valid or not.
1238 This fixes the nickname change bug on channel when changing
1239 the nickname to be same than the old (like nick to Nick) the
1240 nickname formatter doesn't set the new nick anymore to Nick@host.
1241 Affected file lib/silcclient/idlist.[ch].
1243 * Now actually fixed the nickname changing on disconnection.
1244 Added new function silc_change_nick to the Irssi SILC Client.
1245 Affected file irssi/src/silc/core/client_ops.c,
1246 irssi/src/silc/core/silc-nicklist.[ch].
1248 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Check that the public key exists in the GETKEY command before
1251 trying to encode it. Affected file silcd/command.c.
1253 * Print some notifications on received public keys with GETKEY
1254 command in the Irssi SILC Client. Affected files are
1255 irssi/src/fe-common/silc/module-formats.[ch],
1256 irssi/src/silc/core/client_ops.c.
1258 * Use IDENTIFY command to resolve the server information in the
1259 GETKEY command instead of INFO command. Affected file
1260 lib/silcclient/command.c.
1262 * All command reply functions in the client library now calls
1263 the pending command reply callbacks even if an error has
1264 occurred. The server has done this a long time and now it was
1265 time to move the client library to this as well. Now all
1266 errors can be delivered back to the pending command reply
1267 callbacks if necessary. Affected files are
1268 lib/silcclient/command[_reply].[ch].
1270 * Change the nickname on disconnection back to the username
1271 because in reconnect the server will enforce it to it anyway.
1272 Affected file irssi/src/silc/core/silc-servers.c.
1274 * Fixed a config file parsing bug in the Irssi SILC client.
1275 Affected file irssi/src/silc/core/clientconfig.c.
1277 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * When printing the channel mode on JOIN, verify that the
1280 channel key and channel's HMAC are valid. Affected file
1281 irssi/src/silc/core/client_ops.c.
1283 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1286 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1287 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1289 * Removed channel key rekey task deleting from the function
1290 silc_server_save_channel_key. Affected file silcd/server.c.
1291 Added explicit timeout task context instead that is used to
1292 delete the task if we are registering a new task before the
1293 new task has elapsed.
1295 * When channel key rekey occurs the client library now saves
1296 the old channel key for a short period of time (10 seconds) and
1297 is able to use it in case some is still sending channel
1298 messages encrypted with the old key after the rekey. Affected
1299 file lib/silcclient/[idlist.h|client_channel.c].
1301 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * Added check to the silc_server_new_id_real to not accept
1304 new ID if it is the sender's own ID. Affected file is
1305 silcd/packet_receive.c.
1307 * Assure that we do not announce ourself or the one we've
1308 sending our announcements when we're router and are announcing
1309 servers to our primary router. Affected file silcd/server.c.
1311 * Fixed silc_server_command_identify_check_client to assemble
1312 correct WHOIS packet. It send corrupted WHOIS packet and
1313 caused problem with router to router connections. Affected
1314 file silcd/command.c.
1316 Fixed also silc_server_command_whois_check the same way
1317 as for the IDENTIFY command.
1319 * Added new SilcIDListStatus to the server in the SilcIDListData
1320 structure. The status now includes the current status of
1321 the entry (like registered, resolved etc.). Affected file
1322 silcd/idlist.[ch]. Defined a bunch of different status types
1323 as well. This replaced the old boolean registered field as well.
1325 Added resolve_cmd_ident field to the SilcClientEntry structure
1326 too so that if the entry is for example being resolved so
1327 another command may attach to the same pending command reply
1328 without requiring to resolve the same entry again. This concept
1329 should optimize the WHOIS and the IDENTIFY resolving under
1330 heavy load by taking away unnecessary resolving for entries
1331 that are being resolved already.
1333 Added support for adding multiple pending commands for one
1334 command idenfier. Affected file silcd/command[_reply].[ch].
1336 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1337 before deleting the data. Otherwise the hash table will have
1338 freed data in comparison functions. Affected file is
1339 silcd/command_reply.c.
1341 * Fixed silc_idlist_replace_client_id to add the new entry to
1342 the cache with NULL nickname. Otherwise there will be invalid
1343 memory as the nickname after the nickname is freed. Affected
1344 file silcd/packet_receive.c.
1346 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1347 saved into wrong slots because the previous number of entries
1348 was not taken into account. Affected file silcd/idlist.c.
1349 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1351 * If we are router and we receive JOIN notify to a channel that
1352 does not have any users then notified client is marked as the
1353 channel founder, as it is it. The affected file is
1354 silcd/packet_receive.c
1356 * Added to the extended hash table API's table_del_*ext functions
1357 the destructor as argument too, so that the caller can decide
1358 which destructor to use or whether to use destructor at all.
1359 Affected file lib/silcutil/silchashtable.[ch].
1361 * Fixed ID Cache purging. It actually deleted the entries from
1362 the hash table after the data was freed. The hash table ended
1363 up comparing freed memory. The affected file is
1364 lib/silccore/silcidcache.c.
1366 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Fixed Irssi SILC client's KILL command's HELP syntax.
1370 * The USERS command now resolves the detailed user information
1371 if the userinfo field is missing. Affected file is
1372 lib/silcclient/command_reply.c.
1374 * Do not print error in silc_file_read if the read file does
1375 not exist. Just silently return NULL. Affected file is
1376 lib/silcutil/silcutil.c.
1378 * Fixed the silc_log_output to not wine about NULL filename
1379 and to not create some bogus " " filename. Affected file is
1380 lib/silcutil/silclog.c.
1382 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Fixed various printing bugs on the user interface in the
1385 Irssi SILC Client. Minor changes that were forgotten from
1388 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Fixed the configure.in.pre and the compilation and distribution
1391 environment to support the new autoconf 2.52. That version is
1392 now required to compile the CVS trunk.
1394 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1397 to generally parse user@fqdn format strings. Affected file
1398 lib/silcutil/silcutil.c.
1400 * Added nickname_format and nickname_force_format fields to the
1401 SilcClientParams structure. The first one defines the format
1402 for the nicknames that the library will enforce if the receives
1403 multiple same nicknames. The second one is boolean value and
1404 can be used to force the library to always enforce the format
1405 to the nicknames regardles whether there are multiple nicknames
1406 or not. This configurable formatting was employed to flexibly
1407 support accessing multiple nicknames from the user interface.
1408 The userinterface can now set the nicknames to what ever format
1409 they prefer. Affected file lib/silcclient/silcapi.h.
1411 Added function silc_client_nickname_format to the file
1412 lib/silcclient/idlist.c. It performs the nickname formatting.
1414 Added new field `hostname´ to the SilcClientEntry context.
1415 It holds the hostname of the client. Affected file is
1416 lib/silcclient/idlist.h.
1418 * Irssi SILC Client sets the nicknames in nick@hostn format.
1419 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1420 irssi/src/silc/core/silc-core.c.
1422 The WHOIS printing now also shows both the real nickname and
1423 the formatted nickname so that user knows how to access the
1424 user if there are multiple same nicknames cached. Affected
1425 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1426 printing formatting too to take the hostname now as a separate
1427 argument. The Affected file is
1428 irssi/src/fe-common/silc/modules-formats.[ch].
1430 * Changed the silc_client_get_clients_local to accept the formatted
1431 nickname as argument. It accepts the real nickname too but the
1432 formatted nickname can be used to find the true entry from
1433 multiple entries. Affected file lib/silcclient/silcapi.h and
1434 lib/silcclient/idlist.c.
1436 * Added nickname_format_parse field to the SilcClientParams.
1437 It is a callback function provided by the application to parse
1438 the nickname out of the formatted nickname string. The library
1439 calls it to get the nickname from the formatted string. Since
1440 the application generally knows better the format of the nickname
1441 string it parses it instead of the library, even though library
1442 encodes the formatted string. If the callback function is not
1443 provided then the library will use the string as is. The
1444 affected file is lib/silcclient/silcapi.h.
1446 * All the nickname strings passed to the client library in
1447 commands are now expected to be formatted nickname strings.
1448 If the command does not support the formatted nickname string
1449 it will assume that the sent string is the actual nickname.
1450 Affected file lib/silcclient/command.c.
1452 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * Added public key authentication support to OPER and SILCOPER
1455 commands in the client library. Affected file is
1456 lib/silcclient/command.c.
1458 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Changed the get_auth_methdod client operation to be asynchronous.
1461 It can be async if the application resolves the authentication
1462 method from the server during the negotiation. Added new
1463 SilcGetAuthMeth completion callback that the application will
1464 call after resolving the authentication method.
1466 Added function silc_client_request_authentication_method that
1467 the application can use to resolve the authentication method
1468 from the server. Added also SilcConnectionAuthRequest callback
1469 that the library will call after the server has replied. The
1470 application can call this function if it does not know the
1471 current authentication method.
1473 Affected files are lib/silcclient/client.c and
1474 lib/silcclient/silcapi.h.
1476 * The Irssi SILC client now automatically resolves the authentication
1477 method incase any configuration information is not present (and
1478 currently there never is). The affected file is
1479 irssi/src/silc/core/client_ops.c.
1481 * Fixed public key authentication from the client library.
1482 Affected file lib/silcclient/protocol.c. Changed also the
1483 protocol specification about the public key authentication in
1484 the connection authentication protocol. The actual data to be
1485 signed is now computed with a hash function before signing.
1487 * Fixed the public key authentication from the server as well.
1488 Affected file silcd/protocol.c.
1490 * Removed the mlock()'s from the memory allocation routines.
1491 Affected file lib/silcutil/silcmemory.c. The ./configure does
1492 not check anymore for the mlock(). Affected file is
1495 * Fixed USERS command in server to allow the execution of the
1496 command for private and secret channels if the client sending
1497 the command is on the channel. Affected file silcd/command.c.
1499 * Fixed silc_client_get_clients_local to return the clients
1500 count correctly. It could return wrong value. Affected file
1501 lib/silcclient/idlist.c.
1503 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1506 types. The assembler optimizations seemed not to like 64-bit
1507 data types. The assmebler optimizations thus are now enabled
1508 also for BSD systems as opposed to only enable them for Linux.
1510 * Do not check for threads at all on BSD systems. Affected
1511 file configure.in.pre.
1513 * Removed -n and -h options from the Irssi SILC Client since
1514 they are not used in silc.
1516 * Fixed the prime generation to assure that the first digit
1517 of the generated random number is not zero since our conversion
1518 routines does not like number strings that starts with zero
1519 digit. If zero digit is seen the random number is regenerated.
1520 This caused some corrupted RSA keys when the zero first digit
1521 was met. Affected file lib/silcmath/silcprimegen.c.
1523 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Fixed WIN32 configuration in the ./configure script.
1526 Fixed to include xti.h on environments that has it.
1527 Patches by Carsten Ilchmann and andrew.
1529 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Changed the silc_id_create_client_id to be collision
1532 resistant. It is now assured that there cannot be created
1533 two same client ID's. I suspect that some weird bugs in
1534 the server were actually caused by duplicate Client IDs.
1535 Affected file silcd/serverid.[ch]. A router receiving
1536 new ID now also assures and informs the sending server
1537 if the ID caused collision.
1539 * Changed the silc_id_create_channel_id to also assure that
1540 there are no collisions.
1542 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Statement about ignoring the Mutual Authentication flag when
1545 performing rekey with PFS was a bit misleading. It is ignored
1546 if it was set in the initial negotiation, it cannot be even
1547 set in the rekey. Fixed in the ke-auth draft. Started the
1548 new versions of the protocol drafts in the doc/.
1550 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Fixed a bug in silc_client_command_identify_save when saving
1553 new channel information. The channel name was no duplicated
1554 and caused crash on exit. Affected file is
1555 lib/silcclient/command_reply.c.
1557 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Fixed the getkey command handling in the server. Send just
1560 empty OK reply to the sender if the key could not be fetched
1561 (but everything else was ok, like the key just was not available).
1562 Changed the public key parameter to optional in the protocol
1563 specs so that empty OK reply can be sent. Affected file
1566 Added a message to Irssi SILC client to tell to user if the
1567 server did not return a public key.
1569 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Fixed a channel key regeneration bug. It registered new
1572 timeout tasks exponentially until all system resources were
1573 used. Affected file silcd/server.c.
1575 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Added the SILC Document generator to the scripts/silcdoc.
1578 It can be used to generate the Toolkit Reference Manual out
1579 of the source tree. Internally it will also use the RoboDoc
1580 generator now imported in util/robodoc.
1582 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Added couple of return's in rekey protocol if error orccurred
1585 during the protocol. The execution must be terminated.
1586 Affected file silcd/protocol.c. Also, terminate the protocol
1587 always with timeout.
1589 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * The client's Client ID was created initally from the wrong
1592 nickname (it could have been in format nick@host) in the
1593 silc_server_new_client. Affected file silcd/packet_receive.c
1595 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Added some SILC_LOG_ERROR's to various error conditions
1598 if client could not be added to ID cache. Affected files
1599 silcd/packet_receive.c and silcd/server.c.
1601 * When client's sock->user_data is freed, NULL also the
1602 client->router and client->connection pointers. Added check
1603 for these pointers being NULL to various places around the
1604 code. Affected file silcd/server.c.
1606 * Added client->data.registered == TRUE checks to various
1607 places around the code to assure that unregistered client's
1608 are not handled when it is not allowed. Affected file
1611 * Added `bool registered' fields to all
1612 silc_idlist_[server|client]_get_* routines to indicate whether
1613 the fetched client needs to be registered or not. Affected
1614 file silcd/idlist.[ch].
1616 * Add your own entry as registered to the ID cache in the
1617 server. Affected file server.c.
1619 * Fixed a bug in silc_server_new_server. The SilcServer was
1620 set as the new server's context instead of SilcServerEntry.
1621 This naturally caused some weird bugs.
1623 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Do not delete the channel rekey task when adding it
1626 for in silc_server_create_channel_key.
1628 * Changed the silc_server_create_channel_key to return
1629 TRUE or FALSE to indicate the success of the channel key
1632 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * Fixed MSVC++ project files and added missing files to

1643 * Fixed buffer overflow from Irssi SILC Client. Affected
1644 file irssi/src/fe-common/core/themes.c.
1646 * Fixed double free in client library in the file
1647 lib/silcclient/client.c when disconnecting from server.
1649 * Applied double free patch from cras to Irssi SILC client.
1650 Affected files irssi/src/core/[modules/expandos].c
1652 * Fixed the disconnection handling to Irssi SILC Client.
1653 The application must call silc_client_close_connection
1654 in ops->connect client operation in case of failure of
1655 the connection. Affected file is
1656 irssi/src/silc/core/client_ops.c.
1658 * Do not set sock->protocol to NULL in the function
1659 silc_client_close_connection after executing the protocol's
1660 final callback since the sock might not be valid anymore.
1661 Affected file lib/silcclient/client.c.
1663 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Do not enable SILC_THREADS if the linking with libpthread
1666 did not happen. Affected file configure.in.pre.
1668 * Added notion to protocol specification that server must
1669 verify the sent authentication payload with CMODE when
1670 setting the channel founder key. Implemented it to the
1671 server. Affected file silcd/command.c.
1673 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Added _EXTRA_DIST SILC distribution variable to the
1676 distributions file. It is used to conditionally add extra
1677 files or directories to the specific distribution. Affected
1678 files ./prepare, Makefile.am.pre and distributions.

1689 file is silcd/server.c.
1691 * Fixed the lib/silcske/groups.c to work now also with GMP
1692 MP library. The string conversion did not work when using
1693 specific base and the base is indicated in the string as well.
1695 * Created win32/ directory which now includes MSVC++ specific
1696 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1697 It will appear only in the toolkit distribution
1699 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Changed the key material distribution function in case when
1702 the hash output is too short. The data is now concatenated
1703 a bit differently than it used to. Made the change to the
1704 SKE protocol specification.
1706 * Added better GMP detection to configure.in.pre. A patch
1709 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Fixed a minor bug in SKE that might cause some problem on
1712 some platforms. Affected file lib/silcske/silcske.c.
1714 * Added the cookie checking for initiator in the SKE. It checks
1715 that the responder returns the sent cookie unmodified. The
1716 affected file is lib/silcske/silcske.c. Added new SKE
1717 error type INVALID_COOKIE that can be sent during the
1718 negotiation. Fixed some memory leaks as well.
1720 * Added the "invalid cookie" error message to Irssi SILC client's
1723 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Added `task_max' field to the SilcClientParams to indicate
1726 the maximum tasks the scheduler can handle. If set to zero,
1727 default values are used. Affected file lib/silcclient/silcapi.h.
1729 * Fixed memory leaks in silc_client_close_connection. Affected
1730 file lib/silcclient/client.c.
1732 * Added silc_client_del_client_entry to client library to free
1733 all memory of given client entry. Affected file is
1734 lib/silcclient/idlist.[ch].
1736 * Added new functions silc_client_del_channel and
1737 silc_client_del_server to delete channel and server entries.
1738 Affected file lib/silcclient/[silcapi.h/idlist.c].
1740 * Removed silc_client_del_client_by_id from silcapi.h.
1742 * Fixed the INFO command to return the server's own info
1743 correctly when querying by Server ID. Affected file is
1746 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Removed the non-blocking settings in WIN32 code in the
1749 silc_sock_[read/write] and added SleepEx instead. Affected
1750 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1751 of input data is now checked with FIONREAD and ioctlsocket.
1753 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Call silc_schedule_task_del_by_context in the
1756 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1757 Affected file lib/silccore/silcprotocol.c.
1759 * Call silc_protocol_cancel for active protocols in the
1760 silc_server_close_connection if the funtion
1761 silc_server_free_sock_user_data has not been called.
1762 Affected file silcd/server.c.
1764 * Generic tasks cannot be deleted using the del_by_fd
1765 task deleting function since generic tasks does not match
1766 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1768 * Added a notion to SILCOPER help file that the SILCOPER works
1769 only on router server, not on normal server.
1771 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Added for WIN32 support for the new scheduler as well.
1774 Affected file lib/silcutil/win32/silcwin32schedule.c.
1776 * Fixed the SHA1 implementation to work on various platforms.
1778 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1781 API. It is part of the scheduler now. Everything else is
1782 as previously but some functions has changed their names.
1783 Checkout the lib/silcutil/silcschedule.h for the interface.
1784 Updated all applications to use the new interface. Affected
1785 files are lib/silcutil/silcschedule.[ch].
1787 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1789 * Found a bug in the SKE implementation. The HASH value,
1790 specified by the protocol, was not computed correctly. The
1791 public key of the responder was not added to the computation
1792 even though it is mandatory. Affected file lib/silcske/silcske.c.
1793 This unfortunately causes incompatibilities with older
1794 clients and servers.
1796 * Added WIN32 specific network init and uninit functions:
1797 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1798 the Winsock2. Affected file lib/silcutil/silcnet.h and
1799 lib/silcutil/win32/silcwin32net.c.
1801 * Set the socket always to nonblocking mode on WIN32 after
1802 reading data or writing data. Affected file is
1803 lib/silcutil/win32/silcwin32sockconn.c.
1805 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Fixed various compilation problems under WIN32. Affected
1808 files lib/silcutil/win32/silcwin32thread.c and
1809 lib/silcutil/win32/silcwin32schedule.c.
1811 * Removed all _internal.h #includes from public header
1812 files. Internal headers must never be included from
1815 Removed also the lib/silcske/payload_internal.h file.
1817 * All include files that may be needed (public and some others
1818 included by the public headers) by application developers are
1819 now copied to the ./includes directory. It does not copy any
1820 internal headers. Affected file Makefile.defines.pre and all
1821 Makefile.am's under lib/ and subdirs.
1823 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Do not change the ~/.silc directory's permissions automatically.
1826 Affected file irssi/src/silc/core/clientutil.c.
1828 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * Do not cancel the protocol in silc_server_close_connection
1831 it might cause recursion. Now cancelled in the function
1832 silc_server_free_sock_user_data. Affected file silcd/server.c.
1834 * Fixed the silc_server_remove_clients_by_server to regenerate
1835 the channel keys correctly finally. Added also new function
1836 silc_server_remove_clients_channels to actually do it.
1837 Affected file silcd/server.c.
1839 * Fixed the silc_server_new_channel to not crash by giving
1840 wrong router to the new channel. Affected file is
1841 silcd/packet_receive.c.
1843 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1846 which is given as argument to the silc_client_alloc now.
1847 It can be used to configure the client and set various parameters
1848 that affect the function of the client.
1850 * The USERS command in server did not check whether the channel
1851 is private or secret. Affected file silcd/command.c.
1853 * Added new argument to the USERS command in protocol specification.
1854 The USERS command now can take the channel name as argument
1855 as well. Added support for this in client and server and
1856 updated the protocol specs.
1858 * Completed the GETKEY command in client. It can be now used
1859 to fetch also servers public key not only some clients.
1860 Affected files lib/silcclient/command[_reply].c.
1862 * Added silc_client_get_server to return server entry by the
1863 server name. Affected files lib/silcclient/silcapi.h and
1866 * Redefined the IDENTIFY command in protocol specification to be
1867 more generic. It now can be used to query information about
1868 any entity in the SILC Network, including clients, servers and
1869 channels. The query may be based either the entity's name
1870 or the ID. Added support for this in both client and server.
1872 Affected files silcd/command.c and lib/silcclient/command.c
1873 and command_reply.c.
1875 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1876 the _from_client and _from_server functions. Affected file
1879 * Added silc_client_get_channel_by_id_resolve to the file
1880 lib/silcclient/silcapi.h to resolve channel information by
1881 its ID. Added also silc_client_get_channel_by_id that
1882 does not resolve it from the server.
1884 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Added SilcServerEntry context into the client library
1887 to represent one server. The INFO command now allocates
1888 these to save the resolved server info. For now on the
1889 client library will also keep information about servers,
1890 connected and resolved with INFO.
1892 The INFO command now allocates the SilcServerEntry context
1893 and saves the server info there. The COMMAND_REPLY in
1894 the INFO now returns the parameters to application in
1895 same order as defined in the protocol specification.
1897 The entries are cached in the client->server_cache.
1899 * The INFO command is now issued after received the Client ID
1900 from the server. Affected file lib/silcclient/client.c.
1902 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1903 to the application as the mode changer might be server.
1904 It is guaranteed that NULL is not returned anymore to the
1905 application. Affected file lib/silcclient/client_notify.c.
1907 The ID Type is now also passed to the application so that
1908 it can check whether the returned entry is SilcClientEntry
1911 Added new function silc_client_get_server_by_id to return
1912 the server entry by ID. Affected files are the
1913 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1915 * Do not create the channel in the Irssi SILC Client when issuing
1916 the JOIN command but when received the sucessful JOIN command
1917 reply. Otherwise the channel might get created even though we
1918 could not join it. The Affected file is
1919 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1921 * Fixed a channel joining bug in router. The router must also
1922 check the channel modes, invite and ban lists etc. when serving
1923 the JOIN command sent by normal server. Affected file is
1924 silcd/command.c. The router now resolves the client's
1925 information from the server who sent the JOIN command if it
1926 does not know it, and processes the JOIN command only after
1929 * Changed the SilcCommandCb to take new argument; void *context2.
1930 Affected file lib/silccore/silccommand.h
1932 The second argument in the command callbacks in the server now
1933 includes the SilcServerCommandReplyContext if the command was
1934 called as pending command callback from the command reply.
1935 Otherwise it is NULL. When called as pending the status of the
1936 command reply will be checked and if it was erronous the
1937 error will be sent to the original sender of the command.
1938 This way the client always receives the error messages even
1939 though the server was actually the one who received the error
1940 when it resent the command to router, for example. Affected
1941 files silcd/command[_reply].[ch].
1943 * Fixed sending WHOWAS command's error message to client if
1944 the requested client could not be found. It was missing.
1947 * Changed the CMODE and CUMODE commands reply arguments in the
1948 protocol specification. The Channel ID is now sent in both
1949 of the commands to identify the channel. Implemented this
1950 new feature to the client and server. Affected files
1951 lib/silcclient/command_reply.c and silcd/command.c.
1953 * Made better checks for invite and ban lists in the JOIN
1954 command in server. Affected file silcd/command.c.
1956 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * The server now performs the incoming host IP/DNS lookup
1959 using the silc_socket_host_lookup and thus does not block
1960 the server anymore. Affected file silcd/server.c.
1962 * Completed the multi-thread support for SILC Scheduler in
1963 the lib/silcutil/silcschedule.c.
1965 * Fixed the configure.in.pre to detect the pthread correctly
1968 * Fixed a deadlock in silc_task_queue_wakeup in the file
1969 lib/silcutil/silctask.c.
1971 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Added new function silc_schedule_wakeup that is used in
1974 multi-threaded environment to wakeup the main thread's
1975 schduler. It needs to be used when a thread adds a new task
1976 or removes a task from task queues. After waking up, the
1977 scheduler will detect the task queue changes. If threads
1978 support is not compiled in this function has no effect.
1979 Implemented the wakeup mechanism to both Unix and WIN32
1980 systems. Affected files are lib/silcutil/silcschedule.[ch],
1981 lib/silcutil/unix/silcunixschedule.c and the
1982 lib/silcutil/win32/silcwin32schedule.c.
1984 * Added new function silc_task_queue_wakeup to wakeup the
1985 scheduler by the specified task queue. Affected file
1986 lib/silcutil/silctask.[ch].
1988 * The silc_socket_host_lookup_start now wakes up the scheduler
1989 after adding the timeout task. Affected file is
1990 lib/silcutil/silcsockconn.c.
1992 * The silc_socket_host_lookup is synchronous now if the threads
1993 support is not compiled in. However, the callback is still
1994 called asyncronously through the scheduler, anyway. Affected
1995 file lib/silcutil/silcsockconn.c.
1997 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Added new function silc_socket_host_lookup to perform
2000 asynchronous IP and FQDN lookups for the socket connection.
2001 Affected files lib/silcutil/silcsockconn.[ch].
2003 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2006 that may or may not compile the mutex support in.
2008 Changed the silc_mutex_alloc interface. It allocates the
2009 mutex now to the sent pointer and returns TRUE or FALSE.
2011 Affected file lib/silcutil/silcmutex.h.
2013 * Wrote the SILC Task Queue interface to support multi-threads.
2014 Affected file lib/silcutil/silctask.[ch].
2016 * Wrote the SILC Scheduler to support multi-threads. Affected
2017 file lib/silcutil/silcschedule.c.
2019 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2022 in lib/silcutil/win32/.
2024 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Defined SILC Mutex API and SILC Thread API and implemented
2027 them for Unix. Affected files are
2028 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2029 lib/silcutil/unix/silcunixmutex.c and
2030 lib/silcutil/unix/silcunixthread.c.
2032 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Fixed the silc_server_remove_clients_by_server's channel
2035 key re-generation. The hash table handling was incorrect
2036 and would not work with many channels. Affected file is
2039 * Fixed some memory leaks around the server code.
2041 * Rewrote the silc_server_get_users_on_channel to support IPv6
2042 based Client ID's. Affected file silcd/server.c.
2044 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2045 specification. However, a separate document must be written
2046 to define the detailed signing procedure and the payload
2047 associated with the flag. Defined the flag to the
2048 lib/silccore/silcchannel.h as well.
2050 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Changed the dynamic tables to static size tables in the
2053 lib/silccrypt/silchmac.c.
2055 * Removed GCC dependencies from the code. A patch by cras.
2057 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Do not show the error "Error receiving packet bla bla"
2060 in server if it really was not an error (-2 means that reading
2061 is pending). Affected file silcd/server.c.
2063 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Fixed a possible crash in silc_server_remove_clients_by_server
2066 in silcd/server.c. Fixed there also some memory leaks.
2068 * Fixed the silc_idlist_replace_client_id. It could replace
2069 wrong key in the hash table. Affected file silcd/idlist.c.
2071 * Do not check whether there are global users on the channel
2072 if the channel->global_users is FALSE. Affected functions
2073 silc_server_remove_from_one_channel and
2074 silc_server_remove_from_channels in silcd/server.c. Also,
2075 do not check if the removed client is local as we can be
2076 sure that global client was not removed from the channel
2077 and checking for global users is not needed.
2079 * The silc_server_remove_clients_by_server now re-generates
2080 the channel keys correctly for those channels that had
2081 clients removed from them. Affected file silcd/server.c.
2083 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Found the reason of random crashes in the server. We weren't
2086 ignoring the SIGPIPE signal (which can be sent in write())
2087 and it crashed the server. Affected file silcd/silcd.c.
2089 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Assure that sock->user_data is not NULL in the function
2092 silc_server_packet_send in silcd/packet_send.c.
2094 * Disconnect the remote connection if it could not be added
2095 to any ID lists in the server. The affected file is
2098 * Check in silc_server_packet_send[_real/dest] that the
2099 socket is not disconnecting and ignore the data if it is.
2100 Affected file silcd/packet_send.c.
2102 * Define inline to __inline on native WIN32 compilation.
2103 Affected file includes/silcwin32.h.
2105 * Added some explicit type casts for inline code since MSVC
2106 require them. Affected files lib/silcutil/silcbuffer.h,
2107 lib/trq/silcdlist.h and lib/trq/silclist.h.
2109 * Print warning in log files from now on if the packet
2110 decryption fails. Affected file silcd/server.c.
2112 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Changed the `say' client operation's interface to accept
2115 new `type' argument to indicate the type of the message sent
2116 by the library. The application may filter the library's
2117 messages according the type. The affected file is the
2118 lib/silcclient/silcapi.h.
2120 * Added two new functions to lib/silcclient/silcapi.h:
2121 silc_client_del_client and silc_client_del_client_by_id.
2122 Affected file lib/silcclient/idlist.c.
2124 * Moved the clientincludes.h from includes/ to silc/ and
2125 serverincludes.h from includes/ to silcd/.
2127 * The modes for the CMODE and CUMODE are now passed as
2128 uint32 for application with COMMAND_REPLY. The affected
2129 file is lib/silcclient/command_reply.c.
2131 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * /WHOIS without arguments shows client's own information.
2134 Affected file lib/silcclient/command.c.
2136 * Changed PING to not accept any arguments. The specs
2137 says that client can ping only the connected server so
2138 requiring an argument is not needed. Affected file is
2139 lib/silcclient/command.c.
2141 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Fixed a fatal bug in private message sending and reception
2144 encryption and decryption when using private message keys.
2145 The implementation was incorrect and did not follow the
2146 specification. It causd that some of the message were
2147 lost since it did not use the sending and receiving keys
2148 as the protocol suggests. This has been fixed and will cause
2149 incompatibilities with older clients when sending private
2150 message encrypted with private message keys. Affected files
2151 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2152 and various other in Irssi SILC Client.
2154 Added `responder' boolean argument to the functions
2155 silc_client_add_private_message_key[_ske] to indicate when
2156 the key is added as responder or initiator of the key
2159 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Removed the silc_ske_check_version function and created
2162 a SilcSKECheckVersion callback. Added also a function
2163 silc_ske_set_callbacks that is now used to set all SKE
2164 callbacks. The callback functions are not given to
2165 the SKE functions anymore, but this function is used to
2168 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2170 * Added `silc_version' argument to the silc_client_alloc
2171 to define the version of the application for the library.
2172 The library will use the version string to compare it
2173 against the remote host's (usually a server) version
2174 string. Affected file lib/silcclient/silcapi.h
2176 * Added the KE protocol context to Key Agreement context
2177 in client library so that we can abort the SKE if it
2178 is in process when we get timeout. Affected file is
2179 lib/silcclient/client_keyagr.c.
2181 * Do not resolve the client ID forever if it returns in the
2182 first time that such client does not exist. This was done
2183 for example with private message. Affected file is
2184 lib/silcclient/client_prvmsg.c.
2186 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Do not add regex.h for WIN32. The affected file
2189 includes/silcincludes.h.
2191 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2192 not work yet 100%. It generates the DLL's automatically
2193 when compiling with --with-win32 under cygwin.
2195 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * lib/contrib/regex.c is not compiled on WIN32.
2199 * Added silc_net_get_socket_opt function to the
2200 lib/silcutil/silcnet.h.
2202 * Added includes/silcwin32.h for WIN32 specific includes
2205 * Do not use ptime structure or any of the posix process
2206 functions on WIN32 in lib/silccrypt/silrng.c.
2208 * Added silc_gettimeofday to provide generic function
2209 for struct timeval on all platforms. Added the function
2210 to lib/silcutil/silcutil.h.
2212 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2215 library as they clearly belong there. As a plus side we
2216 can make the actual socket connection routines platform
2219 Added also new generic function silc_socket_read and
2220 silc_socket_write (that used to be silc_packet_[read/write].
2221 The implementation of these are platform specific.
2223 * Added WIN32 specific routines of silc_socket_[read/write]
2224 to lib/silcutil/win32/silcwin32sockconn.c.
2226 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Added preliminary support for native WIN32 compilation under
2229 cygwin (using the -mno-cygwin option for GCC) to the
2230 ./configure.in.pre. The --with-win32 now prepares the
2231 compilation for native WIN32.
2233 * Rewrote the SILC Scheduler interface in the file
2234 lib/silcutil/silcschedule.h. The scheduler is now context
2235 based and does not have anymore any global static scheduler.
2236 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2237 and created lib/silcutil/win32 directory for WIN32 based
2240 * Added Unix specific network routines to the
2241 lib/silcutil/unix/silcunixnet.c and the old
2242 lib/silcutil/silcnet.c includes now only generic routines.
2244 Added WIN32 specific network routines to the
2245 lib/silcutil/win32/silcwin32net.c.
2247 * Added Unix specific utility functions from the
2248 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2250 * Added WIN32 SILC Scheduler to the file
2251 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2254 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Do not handle JOIN notify in the server if the target client
2257 is not registered (idata->registered == FALSE). The affected
2258 file is silcd/packet_receive.c.
2260 * Update the nickrec->founder in event_cumode in the Irssi SILC
2261 client. Affected file irssi/src/silc/core/silc-channels.c.
2263 * Fixed the CUMODE_CHANGE notify handling in the server when
2264 server and router are announcing their clients on channels.
2265 Now the mode changes are saved and notified correctly. The
2266 affected file is /silcd/packet_receive.c.
2268 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2269 They really did not replace the cache entry in the ID Cache.
2270 Now they do that. Affected file silcd/idlist.c.
2272 * Fixed the KICK notify handling in the Irssi SILC client to
2273 update the channel records so that the kicked client does not
2274 appear to be on the channel. The affected file is
2275 irssi/src/silc/core/silc-channels.c.
2277 * Always update the conn->current_channel when executing command
2278 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2280 * Fixed the KILL notify handling in Irssi SILC client to remove
2281 the killed client on all channels.
2283 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Fixed the silc_parse_command_line to remove extra spaces
2286 from the start and end of the arguments. Affected file is
2287 lib/silcutil/silcutil.c.
2289 * Cancel and free any active protocol in the function
2290 silc_server_close_connection. Affected file silcd/server.c.
2292 * Cancel and free any active protocol in the function
2293 silc_client_close_connction. Affected file is
2294 lib/silcclient/client.c.
2296 * Do not execute the KILL command for clients that are in
2297 history (ie. they are not in the network). Affected file is
2300 * Fixed KILL notify handling, client does not crash anymore.
2301 Affected file irssi/src/silc/core/silc-channels.c.
2303 * Reduced the default packet buffer size from 2048 to 1024 in
2304 lib/silccore/silcpacket.c.
2306 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2307 counter to the SKE context that is incresed when the SKE library
2308 performs async operation outside the library. If the outside
2309 process frees the SKE context and FREED status will be set
2310 and the library will detect after the sync operation that the
2311 libary is freed. The affected files are
2312 lib/silcske/silcske[_status].[ch].
2314 * Resolve the client entry information in the function
2315 silc_client_channel_message to assure that NULL pointer is not
2316 passed as client entry to the application. */
2318 * Fixed the task timeout calculation to assure that there is
2319 never negative timeouts. The affected file is
2320 lib/silcutil/silcschedule.c.
2322 * Fixed the channel user mode notification sending in server.
2323 It was sent point-to-point to the router (or to server by router)
2324 but it needs to be destined to a channel. The routines now
2325 supports sending the channel user mode notifys to the channels
2326 when announcing clients and channels. Affected files are
2327 silcd/server.c and silcd/packet_receive.c.
2329 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2330 It did not actually replace the old channel entry in the cache.
2331 Affected file lib/silcclient/client_notify.c.
2333 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Fixed a possible crash in silc_packet_send_prepare. It now
2336 assures always that there is enough space in the buffer and
2337 at the tail area of the buffer (for MAC).
2339 Fixed the inbound buffer reallocation in silc_packet_read.
2340 It was old code and did not handle the reallocation correctly.
2343 The affected file is lib/silccore/silcpacket.c.
2345 * Fixed buffer overflow in silc_parse_nickname in the file
2346 lib/silcutil/silcutil.c.
2348 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2350 * make install generates new server keys only if there is not
2353 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2356 Added check that if the NOREPLY is set then we will not send
2357 the away message. This avoids infinite loop of away messages
2358 if both clients are away. The affected file is
2359 lib/silcclient/client_prvmsg.c.
2361 * Fixed client crash if /NICK was given without arguments.
2362 Affected file lib/silcclient/command.c.
2364 * Server does not send the invite list in INVITE command back
2365 to the client if the list was not altered. Added this notion
2366 to the protocol spec as well. Affected file silcd/command.c.
2368 Fixed possible crash in INVITE command by checking the
2369 value of silc_server_get_client_route command.
2371 * Fixed the INVITE notify type handling. The arguments are now
2372 taken in correct order and client does not crash. The affected
2373 file is irssi/src/silc/core/silc-channels.c.
2375 Removed the "Inviting xxx to channel" message from the
2376 client library away and let the application handle it.
2377 Affected file lib/silcclient/command.c. Added that message
2378 to Irssi SILC client's message formats.
2380 * Fixed CMODE command crash in client. It now checks the
2381 amount of arguments correctly and does not crash. The affected
2382 file is lib/silcclient/command.c.
2384 * Do not create new channel automatically in silc_channels_join
2385 but check whether the channel by that name already exists.
2386 Affected file irssi/silc/core/silc-channels.c.
2388 * Do not send the SERVER_SIGNOFF to router if the disconnected
2389 entity was the router. Affected file silcd/server.c.
2391 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2392 SILC client as it was missing from there.
2394 Added the handling of the KICK notify to the Irssi SILC client
2395 as it was missing. Added "you have been kicked" message to
2396 Irssi SILC client's message modules formats.
2398 Added the handing of the KILL notify to the Irssi SILC client
2399 as it was missing. Added the kill message module formats
2402 The affected file is irssi/src/silc/core/silc-channels.c.
2404 * The router did not save the channel mode the server announced.
2405 Affected file silcd/packet_receive.c.
2407 * Fixed a possible crash in INFO command in server. If the
2408 server did not provide the server info it crashed. Affected
2409 file silcd/command.c.
2411 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Fixed the GETKEY command in the server to check also the
2414 global list. Otherwise the GETKEY would not work correctly
2415 in normal SILC server. Affected file silcd/command.c.
2417 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Fixed GETKEY crash, it crashed if the command did not succseed.
2421 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2423 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2424 is now real and not just an macro interface to GMP.
2426 Removed the entire GMP from the source tree and imported new
2427 NSS MPI library instead. Reason for removing GMP is that it is
2428 extremely large and compiles extremely slow. The NSS MPI
2429 is only a few files and compiles in less than 10 seconds.
2430 The speed is also about the same as GMP. The MPI is imported
2431 to lib/silcmath/mpi.
2433 If the system has GMP installed we will still use the GMP.
2434 If it is not then the NSS MPI will be compiled.
2436 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Merged a long nickname (127 characters long) crash bugfix from
2439 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2441 * Merged a freed memory reference bugfix from Irssi CVS tree.
2442 Affected file irssi/src/core/commands.c.
2444 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Added the server's public key sving and verification to the
2447 server when performing the SKE. This was missing and the
2448 remote server's (or router's) public key was accepted without
2449 checking whether we have it previously or trust it at all.
2450 Affected file silcd/protocol.c.
2452 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Check in the silc_server_timeout_remote if protocol is active
2455 and make sure that the protocol's final callback is called so
2456 that all memory if freed. Affected file silcd/server.c.
2458 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * silc_server_whois_send_reply crashed the server if the nickname
2461 was 127 characters long. Affected file silcd/command.c.
2463 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Added sanity check to the silc_server_new_client. If the hostname
2466 is provided inside username then check that the provided hostname
2467 really is the same as the resolved one. If the hostname was not
2468 resolved then check it from the public key. Affected file is
2469 silcd/packet_receive.c.
2471 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2472 if the server disconnected us and the connection is not valid
2473 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2475 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2476 the library to the lib/silcutil/silcutil.[ch].
2478 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Close log file after open. Affected file
2481 lib/silcutil/silclog.c.
2483 * Check whether sock == NULL in silc_client_send_packet and return
2484 if it is. Affected file lib/silcclient/silcclient.c.
2486 * Check rec->entry == NULL in the Irssi SILC Client before
2487 sending the channel message. Affecte file is
2488 irssi/src/silc/core/silc-servers.c.
2490 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Merged a splitted window bugfix from Irssi CVS tree. The
2493 affected file is irssi/src/fe-text/textbuffer-view.c.
2495 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2496 It did not print nickname.
2498 * Improved the distributions system a bit.
2500 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2502 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2503 irssi/src/fe-text/gui-window.c.
2505 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2506 to in-active server. The affected file is
2507 irssi/src/silc/core/client_ops.c.
2509 * Resolve the client in USERS command reply if the entry does
2510 not have username resolved. The affected file is
2511 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2512 command to WHOIS command to really resolve stuff. The USERS
2513 is not used any more in any critical section so WHOIS can
2514 be used even though it might be slower than IDENTIFY.
2516 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2519 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Changed the protocol API a bit more consistent in the
2522 lib/silccore/silcprotocol.[ch].
2524 * Changed the following headers to ROBODoc format:
2526 lib/silccore/silcpayload.h
2527 lib/silccore/silcprotocol.h
2528 lib/silccore/silcsockconn.h
2530 All core library headers are now formatted.
2532 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Fixed a bug in Irssi SILC client; do not show that you are
2535 server/router operator if you really are not. Affected file is
2536 irssi/src/silc/core/client_ops.c.
2538 * Renamed silc_command_free_payload to silc_command_payload_free.
2539 Affected file lib/silccore/silccommand.h
2541 * Added silcmath.h to include the prototoypes of various routines
2542 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2545 * Changed the following headers to ROBODoc format:
2547 lib/silccore/silcchannel.h
2548 lib/silccore/silccommand.h
2549 lib/silccore/silcid.h
2550 lib/silccore/silcidcache.h
2551 lib/silccore/silcmode.h
2552 lib/silccore/silcnotify.h
2553 lib/silccore/silcpacket.h
2554 lib/silcmath/silcmath.h
2556 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Added checking to the server code not to start the server if
2559 ciphers and stuff are not configured properly. Affected files
2560 silcd/serverconfig.[h] and silcd/server.c.
2562 * Changed the layout of the header files of the public interfaces
2563 in the SILC libraries. The new layout supports ROBODoc
2564 documentation tool (and some others) so that it is easy to create
2565 a library reference manual. All the other headers and source
2566 code must still follow the CodingStyle document. Also source
2567 code must not include these ROBODoc stuffs, only the headers.
2568 Furthermore, all public interface headers must now be named
2569 by using `silc' prefix, example: silcapi.h, silccipher.h.
2570 Some files were renamed due to this. All the other headers
2571 must not be used as public interfaces. I will update the
2572 CodingStyle document later. Changed following headers, so far:
2574 lib/silcclient/silcapi.h
2575 lib/silccore/silcauth.h
2576 lib/silccore/silcprivate.h
2577 lib/silccrypt/silcdh.h
2579 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Removed silc_client_packet_send_flush from the client library
2584 as it is not needed. Affected file lib/silcclient/client.[ch].
2586 * Added printing of message of unresolved authentication method
2587 to the Irssi SILC client. Added it to the module formats.
2588 Removed the same message from the client library.
2590 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Added new distribution feature, DISTLABEL. Every distribution
2593 can define own preprocessor label that can be used in the
2594 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2595 file distributions, acconfig.h.pre and prepare.
2597 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Added Makefile.defines_int to include the actual definitions
2600 for Makefile.defines.in. Tested the new distribution system,
2601 created distributions and tested installation.
2603 * Added AWAY message printing to the Irssi SILC client. Added
2604 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2606 * Added SCONNECT command to call the SILC's CONNECT command.
2607 Cannot use CONNECT directly since Irssi uses that internally.
2608 Affected file irssi/src/silc/core/silc-servers.c.
2610 Added ACTION local command. It is same as ME command but takes
2611 the channel as mandatory argument.
2613 Rewrote some of the Irssi's help files to suite for SILC
2616 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Added Makefile.defines[.in] that should for now on be included
2619 in all Makefile.am file in the source tree. That file includes
2620 all common compilation definitions for SILC source tree.
2622 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Minor changes to the ./prepare script to change the package
2625 name according the distribution name to the configure.in.
2627 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Created new distribution system. Added file `distributions'
2630 that defines all the distributions that can be created out of
2631 the SILC source tree. The ./prepare script now reads that
2632 file to determine how to prepare the distributions. The
2633 first argument to the ./prepare is the name of the distribution
2634 and second is the version of the distribution. If given
2635 without arguments it creates the default (toolkit) distribution
2636 with the default version (defined in ./prepare).
2638 All Makefile.am files that are subject to the distributions
2639 are now named as Makefile.am.pre. These are ./Makefile.am
2640 and lib/Makefile.am. Others may be changed later.
2642 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Added invite list, ban list, some key management and connection
2645 error message printing to module formats in the Irssi SILC client.
2647 * Added new silc_client_set_away_message to set the away message
2648 that is back to the person who sent private message. The
2649 affected file lib/silcclient/silcapi.h and the
2650 lib/silcclient/client_prvmsg.c.
2652 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Fixed the private message sending in the Irssi SILC client,
2655 added local command KEY to the Irssi SILC client.
2657 Added key management and key agreement message formats to the
2658 irssi/src/fe-common/silc/module-formats.[ch].
2660 Added USERS (alias WHO) printing, server/router operator
2661 indication and LIST command printing to the module formats.
2663 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2665 * Fixed channel joining notify handling, cumode notify handling
2666 from Irssi SILC client.
2668 * Added SILC specific module-formats to the Irssi SILC client so
2669 that SILC specific message hilighting, colors etc is possible.
2670 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2672 Added channel mode, channel user mode, actions, notices,
2673 whois and whowas printing to the the module-formats.c.
2675 * Fixed a bug in channel deletion in the server. The channel
2676 is not left to the cache even if the channel founder auth mode
2677 is set when there are no users anymore on the channel. Affected
2678 file silcd/server.c.
2680 * The silc_net_localhost now resolves the entire hostname including
2681 the domain name. Affected file lib/silcutil/silcnet.c.
2683 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Changed the ask_passphrase client operation to be ascynchronous.
2686 It has now a completion callback and a context that the
2687 application must call after it has got the passphrase from
2688 the user. Affected files lib/silcclient/silcapi.h,
2689 lib/silcclient/protocol.c, lib/silcclient/command.c and
2692 Added SilcAskPassphrase callback that the application calls
2693 to deliver the passphrase to the library.
2695 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2696 The public key verification and especially a certificate
2697 verification is asynchronous procedure.
2699 Added new SILC_SKE_STATUS_PENDING status to indicate the
2700 request is pending and a callback will be called to finalize
2703 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2704 indicate that remote end did not send its public key (or
2705 certificate), even though we require it. Added check for this
2706 condition in the SKE. This was a security bug, now fixed.
2708 Defined new SilcSKEVerifyCbCompletion callback that is called
2709 when the verification process is completed.
2711 The affected files lib/silcske/silcske_status.h and
2712 lib/silcske/silcske.[ch].
2714 * Changed the verify_public_key client operation to be async
2715 as well. Defined SilcVerifyPublicKey callback that is used to
2716 indicate the success of the public key verification process.
2718 Changed the server and client to use the new async client
2721 * Changed the Irssi SILC client's internal scheduler to be called
2722 twice as many times as it used to be. As a result the client
2723 should be a bit faster now. Affected file is
2724 irssi/src/silc/core/silc-core.c.
2726 * Added support to Irssi SILC client of asynchronous public key
2727 verification and passphrase inquiry. Affected file is
2728 irssi/src/silc/core/silc-core.c.
2730 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * Do not say "You have left channel %s" in client library.
2733 Moved it to the application. Affected files are
2734 lib/silcclient/command.c and silc/client_ops.c.
2736 * Fixed silc_client_get_clients. Command context was not
2737 duplicated and was freed memory in the callback. Affected
2738 file lib/silcclient/idlist.c.
2740 * Do not say "you are now talking..." on JOIN command in the
2741 client library. The appliation must handle it.
2743 * Do not say ".. changed topic to" in command reply in the
2744 client libary. The application must handle it.
2746 * Fixed TOPIC command sending in the client library.
2748 * Fixed a memory leak in silc_client_command_free in the file
2749 lib/silcclient/command.c.
2751 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Imported a modified version of Irssi client to the source tree.
2754 The Irssi will be used to create a new client called
2755 Irssi SILC. Imported to irssi/.
2757 Added silc_core_init_finish function to the Irssi. Affected
2758 file irssi/configure.in.
2760 A lot changes in the Makefile.ams around the irssi tree.
2762 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Do not rehash if the new size is same as the old size of the
2765 hash table, in the silc_hash_table_rehash*. The affected file
2766 lib/silcutil/silchashtable.c.
2768 * Replaced hash_table_del_by_context calls from the server
2769 (when channel->user_list and client->channels) to the
2770 hash_table_del as it is sufficient and faster.
2772 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2774 * Added silc_hash_table_list, silc_hash_table_get and the
2775 SilcHashTableList structure to provide an alternative way to
2776 traverse the hash table. The affected files are
2777 lib/silcutil/silchashtable.[ch].
2779 * Changed the server's idlist routines to use the hash table
2780 routines to optimize the code.
2782 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Replaced the client entry's `channel' list and channel entry's
2785 `user_list' list to hash tables for optimized lookup. Changed
2786 the code to use the hash table interface around the code.
2787 Affected file lib/silcd/idlist.[ch].
2789 * Added `auto_rehash' boolean argument to the function
2790 silc_hash_table_alloc to indicate whether the hash table should
2791 auto-rehash when it thinks is appropriate time. It will
2792 increase the hash table size if the there is twice as much
2793 entries in the table than the size of the table, and will
2794 decrease the size if there are twice as less entries than
2795 the size of the table.
2797 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2799 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2801 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * silc_idcache_purge_by_context deletes the entry now by context
2804 as it is supposed to do. Affected file lib/silccore/idcache.c.
2806 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2807 client is not anymore valid (WHOWAS givens the info) and not
2808 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2810 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Removed the `data' and `data_len' arguments from the ID Cache
2813 interfaces and added `name' argument. ID Cache does not handle
2814 anymore the binary data only a names associated with given ID.
2816 * When hashing a Client ID with silc_hash_id the entire ID is
2817 not hashed anymore, instead only the hash of the Client ID is
2818 hashed. This way we can access the Client ID from the cache
2819 with Client ID but with the hash of the ID (which is a hash of
2820 the nickname) as well without any difference in performance.
2822 Added also silc_idcache_find_by_id_one_ext to do one on one
2823 searching when we have the actual ID. Added also function
2824 silc_hash_client_id_compare. The affected files are
2825 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2827 * When hashing the name associated with a ID it is always done
2828 in lowercase. This way we can access the cache without worrying
2829 about case-sensitivity, even though, for example nicknames are
2832 * Fixed a bug in server with channel message sending. It put
2833 wrong ID type as destination ID. The affected file
2834 silcd/packet_send.c.
2836 * silc_idcache_del_by_context now deletes from all hash tables
2837 by context. Affected file lib/silccore/idcache.c.
2839 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * Changed the client library to use the new ID Cache interface.
2842 Changes around the source tree.
2844 * Added silc_hash_table_rehash_ext to rehash with specific
2845 hash function. Affected file lib/silcutil/silchashtable.[ch].
2847 * Added silc_hash_string_compare to compare two strings in the
2848 hash table. Affected file lib/silcutil/silcutil.[ch].
2850 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added new function silc_idcache_del_by_context into the
2853 lib/silccore/idcache.[ch].
2855 * Changed the server's ID list routines to use the new ID Cache
2856 interface. Changes around the source tree.
2858 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Added silc_hash_table_del[_by_context]_ext functions in to the
2861 lib/silcutil/silchashtable.[ch].
2863 Removed silc_hash_table_find_all* routines and added new
2864 silc_hash_table_find_foreach to replace them.
2866 Added silc_hash_table_replace_ext function as extended
2867 replacing function. Separated the simple hash table interface
2868 from the extended hash table interface in the file
2869 lib/silcutil/silchashtable.h.
2871 * Fixed minor bugs and changed it to use some of the new
2872 hash table functions in lib/silccore/idcache.c
2874 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Added new function silc_hash_table_find_all to return all keys
2877 in the hash table by the specified key. As the hash table is
2878 collision resistant it also makes it possible to have several
2879 duplicate keys in the hash table. This function may be used to
2880 find all of the keys from the hash.
2882 Added user_context arguments to the SilcHashFunction,
2883 SilcHashCompare and SilcHashDestructor to deliver user specified
2886 Added new fuctions silc_hash_table_find[_all]_ext to do
2887 extended lookup with specified hash and compare functions and
2888 specified user contexts.
2890 Added new function silc_hash_table_add_ext to add the key
2891 with specified hash function and user context.
2893 Added new function silc_hash_table_foreach to traverse all
2894 entrys in the hash table. Added SilcHashForeach callback
2897 Added new function silc_hash_table_del_by_context to delete
2898 the entry only if the context associated with the key matches.
2900 Affected files are lib/silcutil/silchashtable.[ch].
2902 * Removed silc_hash_[server/client/channel]_id and added just
2903 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2904 silc_hash_id_compare to compare two ID's using as the hash table
2905 comparison function. Added also silc_hash_data to hash
2906 binary data and silc_hash_data_compare to compare it.
2908 * Removed silc_idlist_find_client_by_hash as it is not needed
2909 anymore. Affected file silcd/idlist.[ch].
2911 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2912 to use internally the SilcHashTable. The new ID Cache is a lot
2913 faster than the old one. Some of the ID Cache interface was also
2914 rewritten and obsolete and stupid functions were removed.
2916 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2918 * Added entry_count field to the SilcHashTable to keep the number
2919 of the entries in the table. Implemented the function
2920 silc_hash_table_rehash. Added new function
2921 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2923 Fixed a minor bug in silc_hash_table_free.
2925 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2926 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2927 into the lib/silcutil/silcutil.[ch].
2929 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Implemented a collision resistant hash table into the
2932 lib/silcutil/silchashtable[ch]. See the header and the source
2933 for the SilcHashTable API.
2935 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Merged dotconf version 1.0.2 into lib/dotconf.
2939 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Do not compile anything in lib/silcsim/* if the SIM support
2942 is not enabled. The tree should now compile without problems
2945 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Compiled the SILC under cygwin. Compiled and tested briefly
2948 without problems. More tests needed. The SIMs didn't compile
2951 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2953 * Fixed possible crash in silc_get_username in the
2954 lib/silcutil/silcutil.c.
2956 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Fixed a va_arg in silc/client_ops.c.
2960 * Oops, RC5 routines were named AES and caused some problems
2961 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2963 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Added new SilcIDIP structure into the lib/silccore/id.h and
2966 replaced the old `ip' fields from all SILC ID's to that type.
2967 This is a step towards IPv6 support.
2969 The silc_id_get_len takes now the ID as an extra argument.
2970 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2971 both IPv4 and IPv6 based ID's.
2973 The affected files are lib/silccore/id.[ch] and other files
2974 around the tree using these routines.
2976 * Removed the ID length arguments in server from various
2977 silc_server_send_notify_* routines -> they are not needed
2980 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Fixed memory leak in silc_encode_pem_file in the file
2983 lib/silcutil/silcutil.c.
2985 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Check minor version as well in the SKE. Affected files are
2988 silcd/protocol.c and lib/silcclient/protocol.c.
2990 * Added --identifier option to the server so that an identifier
2991 can be when creating the public key for the server. Affected
2992 file is silcd/silcd.c.
2994 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2995 lib/silccrypt/silcpkcs.c.
2997 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Register default ciphers and stuff when using -C option with
3000 the server. Affected file sildc/silcd.c.
3002 * Put back the servers public key filename format, it is better
3003 than the new one. For now, the client keys are saved with the
3004 new filename format. The affected file silc/client_ops.c.
3006 * Implemented the Cipher API for the rest of the ciphers that
3007 did not implement it or implemented it the wrong way.
3009 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Register default ciphers and stuff when using the -S option
3012 in the client. Affected file silc/silc.c. Same also when
3013 creating new key pair with -C option.
3015 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Fixed the silc_verify_public_key client operation function to
3018 save the public keys differently. The fingerprint is now
3019 used as filename and not the hostname. This way also the
3020 client keys are saved uniquely and not with hostnames. The
3021 affected file is silc/client_ops.c.
3023 * Trimmed the silc_hash_fingerprint function to remove extra
3024 whitespaces from the end of the fingerprint. The affected
3025 file is lib/silccrypt/silchash.c.
3029 * Added silc_cipher_register_default function to register all
3030 default ciphers. It can be used when configuration files
3031 does not exist and the application does not want any specific
3032 ciphers in any specific order.
3034 The SilcDList is now used as silc_cipher_list dynamically
3035 allocated cipher list. Removed the static list all together
3036 and now all ciphers must be allocated to the dynamic list.
3037 The silc_cipher_alloc routine was changed to check only the
3040 All silc_cipher_* routines that used to return int returns
3043 The affected files lib/silccrypt/silccrypt.[ch].
3045 * The same thing was done to silc_hash_* as for silc_cipher_*
3046 routines. Affected files lib/silccrypt/silchash.[ch].
3048 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3049 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3050 Added also silc_pkcs_[un]register[_default] functions.
3051 Removed the data_context from the PKCS API.
3053 * Added silc_hmac_register_default function to register default
3054 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3055 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3056 to unregister all hmacs at once.
3058 * Register the default ciphers, hash functions, PKCSs and HMACs
3059 if client's configuration file does not exist. The affected
3062 * The client did not load the hash functions from the SIM
3063 modules at all. Added support for this. Affected file is
3064 silc/clientconfig.c.
3066 * When decoding public key with silc_pkcs_public_key_decode, check
3067 the supported algorithm only if PKCS are registered. Affected
3068 file lib/silccrypt/silcpkcs.c. The same was done with the
3069 silc_pkcs_private_key_decode.
3071 * Fixed the SILC List routines to keep the list always in order.
3072 It used to change the list's order when traversing the list but
3073 not it preserves the order. Affected file lib/trq/silclist.h.
3075 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Added the client library to use the SilcSocketConnection's
3078 reference counter (by silc_socket_dup) to prevent the bug that
3079 the socket object may be freed underneath async operation.
3081 * The name resolv library checking fixes in the configure.in.pre.
3084 * Created new version of the protocol drafts for future
3085 development. The -03 drafts are the ones that will be changed
3086 in the trunk now and the -02 will remain as they are.
3088 * Send list of CUMODE notifys to the router when announcing
3089 the channel users to the router. Affected file silcd/server.c.
3090 If the router receiving channel founder CUMODE for a channel
3091 that already has channel founder it will send CUMODE notify
3092 to the sender to remove the channel founder rights from the
3093 announced client. Affected file silcd/packet_receive.c.
3095 * The CUMODE notify may now use Server ID as well as the entity
3096 who changes the mode. Updated protocool specs.
3098 * Updated INSTALL and README files.
3100 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * New web pages in the http://silc.pspt.fi. The pages was
3107 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Implemented the [DenyConnectin] config section in the server.
3110 Added silc_server_config_denied_conn to check whether incoming
3111 connection is denied. Affected file silcd/serverconfig.[ch].
3113 * Do not check the ports when checking the incoming configuration
3114 data if the port is 0, meaning any. Affected file is
3115 silcd/serverconfig.c.
3117 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Fixed buffer overflow in silc_string_compare in the file
3120 lib/silcutil/silcutil.c.
3122 * Fixed double free in silc_server_command_leave in the file
3125 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Fixed the version checking in the server. Affected file is
3130 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Fixed the configuration data fetching when accepting new
3133 connections in the server. Affected file silcd/server.c.
3135 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Added `sender_entry' argument to the function
3138 silc_server_packet_relay_to_channel so that we can check
3139 whether some destination actually belongs to the same route
3140 the sender belongs (ie, we must not resend the packet to the
3141 sender). Affected file silcd/packet_send.[ch].
3143 * Added `servername' field to the SilcClientEntry in the server
3144 to hold the name of the server where client is from. Affected
3145 file is silcd/idlist.h.
3147 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Moved the channel message encrypting in the router betwen
3150 router connections from silc_server_channel_message to the
3151 silc_server_packet_relay_to_channel since we want to check
3152 whether we have anybody channel before encrypting anything.
3153 Affected files silcd/packet_[receive/send].c.
3155 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Fixed the [AdminConnection] server config section to support
3158 multiple entries. Affected file silcd/serverconfig.c.
3160 * Added support into the server to check the validity of the
3161 incoming connection before executing any KE or authentication
3164 * The connection configuration is now saved to the KE and
3165 connection auth protocol contexts and not fetched anymore in
3166 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3168 * The local hosts listenning address and port is also resolved
3169 now when starting the server. We want to have the socket object
3170 to include the real address and port for the listener. Added
3171 new function silc_net_check_local_by_sock into the files
3172 lib/silcutil/silcnet.[ch].
3174 * Fixed a broadcast bug in server -> do not broadcast if we
3177 * Fixed a routing bug. Do not route broadcast packets ever.
3178 Broadcast packets must be processed always and not routed since
3179 they may be destined to some other host than yourself and thus
3180 would get routed without no good reason. Affected file is
3183 * Added function silc_server_config_is_primary_route to check
3184 whether primary router connection has been configured (a router
3185 configuration that we are initiating). If there is not, we
3186 will assume that there is only two routers in the SILC network
3187 and we will use the incoming router connection as our primary
3188 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3190 * Changed the order of the broadcasting. Broadcast _after_ the
3191 packet has been processed not before. Affected file is
3194 * Fixed a [ClientConnection] parsing bug. The port was never
3195 parsed correctly thus resulting to port 0. Affected file
3196 silcd/serverconfig.c.
3198 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3199 argument and did not set the broadcast packet flag. Affected
3200 file silcd/packet_send.c. Fixed same bug in the function
3201 silc_server_send_notify as well.
3203 * If we receive NEW_ID packet for our own ID in the server, ignore
3206 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Removed the nickname from the Private Message Payload.
3211 Updated the code and the protocol specs.
3213 * Updated protocol specs for submitting to the IETF.
3215 * Tweaked the Random Number Generator a bit. Affected file
3216 lib/silccrypt/silcrng.c. Exported a new function
3217 silc_rng_[global]_add_noise which can be used to add more
3220 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Do not parse packets with different timeout when protocol
3223 is active -> may cause problem with rekey. Affected file
3226 * When server receives signoff notify it must not create
3227 new channel key if the client is on any channels since the
3228 sender of the signoff notify will create it.
3230 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Added printing of error messages during SKE protocol from the
3233 failure packet sent by server during SKE. Affected file
3236 * Removed the client's failure_callback handling with timeout
3237 and handle it immediately when received.
3239 * The SKE library returned wrong type in SUCCESS and FAILURE
3240 packets. They must be 32 bit MSB not 16 bit MSB.
3242 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Ok, rewrote the logic of the re-key and now it seems to work.
3245 I tested it on high traffic with frequent re-keys without
3246 problems. Added hmac_receive (and renamed hmac to hmac_send)
3247 in SilcClientConnection in lib/silcclient/client.h and
3248 in SilcIDListData in silcd/idlist.h. Also, removed the
3249 SilcPacketParserContext's cipher and hmac fields as they are
3250 not needed anymore and actually caused some problems when
3251 the ciphers and hmac's changed underneath the packet parser.
3253 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * If re-key protocol is active then process the incoming packets
3256 synchronously since we must assure that icoming packets encrypted
3257 with the old key is processed before the new keys is set to
3258 use. This is true other packets than for REKEY packets.
3259 Affected file silcd/server.c. The same was done to client library
3260 as well, affected file lib/silcclient/client.c.
3262 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Fixed bug in client and server to accept the force send if
3265 the packet is send from silc_[server/client]_packet_process
3266 function. Otherwise the packets are never delivered, oops.
3268 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Disable force sending of packets when REKEY protocol is active.
3271 We must assure that no packet is sent directly when rekey is
3272 performed. All packets must be sent through packet queue.
3273 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3274 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3275 function is silc_[server/client]_packet_send_real to check
3278 * Replaced the SIM paths from example config files to
3279 /usr/local/modules. Also, make install creates now
3280 /usr/local/silc/logs directory to hold all the SILC server
3283 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3285 * Made the configure.in.pre work on Solaris. Patch by salo.
3287 * Made all ciphers compatible with non-x86 machines. Defined
3288 CBC mode macros into lib/silccrypt/ciphers_def.h.
3290 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Fixed the make install.
3294 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * When MAC computation fails the silc_packet_decrypt returned 0
3297 even though it was supposed to return -1. Fixed this. The
3298 affected file is lib/silccore/silcpacket.c.
3300 * Do not replace the config files in /etc/silc (in make install)
3301 if they already exist. Affected file ./Makefile.am.
3303 * Do not send re-key packets immediately but through packet queue.
3304 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3306 * Changed silc_net_check_host_by_sock to return FALSE if the
3307 IP/DNS could not be resolved. Though, it returns the IP address
3308 now even if it could not resolve it (but returns also FALSE).
3309 Affected file lib/silcutil/silcnet.[ch].
3311 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Added silc_pkcs_decode_identifier to decode the public key's
3314 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3315 Added also silc_pkcs_free_identifier. Added also new context
3316 SilcPublicKeyIdentifier.
3318 * Added -S option to the silc client. It is used to dump the
3319 contents of the specified public key file.
3321 * Changed the PKCS api to return the public key length when
3322 setting the public key.
3324 * Fixed a fatal bug in the public and private key file loading.
3325 Affected file lib/silccrypt/silcpkcs.c.
3327 * Execute the packet parsing for client with zero (0) timeout
3328 if the protocol is active. Affected file silcd/server.c.
3330 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3332 * Made the key generation options to the silcd program. Added
3333 -C option, equivalent to client's option.
3335 * Added new [ServerKeys] config section to the server. It
3336 configures the server's public and private key.
3338 * Defined generic Public Key Payload into the protocol
3339 specification to send specific type of public keys and
3342 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3343 public key or certificate.
3345 * Implemented the GETKEY command to the server and to the
3346 client library and on user interface.
3348 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Made preliminary `make install' work.
3352 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Added SilcServerRekey context into silcd/idlist.h.
3356 * Added the PFS support as defined in the specification to the
3357 SKE protocol. Affected files lib/silcske/*.c.
3359 * Added `ske_group' field to the SilcServerRekey context to hold
3360 the number of the SKE group that is used with PFS in re-key.
3361 Affected file silcd/idlist.h.
3363 * Added PFS re-key support to the server. Affected file is
3366 * Added silc_protocol_cancel to cancel execution of the next
3367 state of the protocol. Affected file is
3368 lib/silccore/silcprotocol.[ch].
3370 * Added the re-key support with and without PFS to the client
3371 library. Re-key is performed once in an hour, by default.
3373 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3374 Added silc_client_rekey_callback and silc_client_rekey_final.
3375 Affected files are lib/silcclient/protocol.[ch] and
3376 lib/silcclient/client.[ch].
3378 * Removed the `hmac_key' and `hmac_key_len' fields from the
3379 SilcClientConnection structure; not needed. Affected file is
3380 lib/silcclient/client.h.
3384 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Do not ask whether user wants to use the negotiated private key
3387 for private messages, just use it. Affected file is
3388 silc/local_command.c.
3390 * Added `send_enc_key' and `enc_key_len' fields to the
3391 SilcIDListData structure since they are needed in the re-key
3392 phase. Affected file is silcd/idlist.[ch].
3394 * Implemented the simple re-key protocol into the server.
3395 Affected files silcd/server.c and silcd/protocol.[ch]. The
3396 re-key will be performed once in an hour, by default.
3398 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3399 Added silc_server_rekey, silc_server_rekey_callback and
3400 silc_server_rekey_final.
3402 * Removed Tunneled flag from the protocol. Updated the code
3403 and the specifications.
3405 * Adde `pfs' field to the SilcIDListData to indicate whether
3406 the PFS is to be performed in the re-key. Affected file is
3409 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3412 int64 of at least the xintXX size. If void * is less that 4
3413 bytes uint32 * will be used. Defined bool as boolean.
3415 * Changed _ALL_ unsigned long and unsigned int to uint32,
3416 unsgined short to uint16 in the source tree.
3418 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3419 not handle clients that has entry->data.registered == FALSE.
3420 They are not in the network anymore. Affected file is
3423 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Implemented the sending of the SERVER_SIGNOFF notify in the
3426 server. Affected file is silcd/server.c.
3428 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3429 Added also silc_notify_payload_encode_args into the
3430 lib/silccore/silcnotify.[ch].
3432 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3433 Affected file silcd/packet_receive.c.
3435 * Implemented the SERVER_SIGNOFF notify handling in the client
3436 library. Affected file lib/silcclient/client_notify.c. Also,
3437 implemnted the printing of the SERVER_SIGNOFF info to the
3438 application. Affected file silc/client_ops.c.
3440 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3441 if the deleting was successful. Affected file silcd/idlist.[ch].
3443 * Added support for public key authentication in the connection
3444 authentication protocol in the client library. Affected file
3445 lib/silcclient/protocol.c.
3447 * Changed the server's silc_idlist_get_clients_by_* interface
3448 to support already allocated array so that new entries may be
3449 added to pre-allocated array. Affected file silcd/idlist.[ch].
3450 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3451 and command replies.
3453 * All command reply functions in the server now calls the
3454 pending command callback even if error occured. This way the
3455 error will be delivered to the client as well. Affected files
3456 silcd/command.c and silcd/command_reply.c.
3458 * Fixed INFO command to return local server's info if no server
3459 was provided. Affected file lib/silcclient/command.c.
3461 * Removed RESTART command for good. Updated the code and the
3464 * Rewrote parts of the task system. It is a bit simpler now.
3465 Removed unsued task priorities. The affected files are
3466 lib/silcutil/silctask.[ch].
3468 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Moved the USERS printing from the library to the application.
3471 Affected files lib/silcclient/command.c and silc/client_ops.c.
3473 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Added channel key re-key support. The re-key is perfomed
3478 only by the router and is done once in an hour. Added `rekey'
3479 field to the SilcChannelEntry in the server. Affected files
3480 silcd/server.c and silcd/idlist.h.
3482 * Added silc_task_unregister_by_context into the file
3483 lib/silcutil/silctask.[ch].
3485 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Added SILC_UMODE_GONE mode to indicate when the client is not
3488 present in the SILC network. Added also support to the local
3489 command AWAY that will set this mode. Added support of showing
3490 "xxx is gone" in WHOIS command. The USERS command shows the
3491 gone status as well.
3493 * Fixed setting server and router operator privileges in the
3494 server's UMODE command. Affected file silcd/command.c.
3496 * Merged the SKE KE1 and KE2 payloads into one payload. The
3497 new KE payload is equivalent to the old KE2 payload.
3499 Cleaned up the SKE Start Payload parsing. It now uses the
3500 simple buffer unformatting to do the parsing. A lot faster
3503 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3504 to the SKE that is used to indicate whether both of the SKE
3505 parties should perform authentication. By default only the
3506 responder performs authentication. By setting this flag also
3507 the initiator must do authentication. By default it is unset
3508 since in normal SKE case, client to server connection, only
3509 the responder should do authentication. When doing SKE between
3510 two clients both should perform authentication. Updated the
3511 code and the protocol specs.
3513 * A little fix to IDENTIFY command in the server. Search the
3514 client first by hash not nickname. Affected file is
3517 * Fixed the silc_client_close_connection to support closing
3518 the client to client connections wihtout deleting too much
3519 data. Affected file lib/silcclient/client.c.
3521 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3522 are received if protocol used to be active but is not anymore
3523 the application would crash due to NULL pointer dereference.
3524 Affected files silcd/server.c and lib/silcclient/client.c.
3526 * Added `hash' field to the SilcClientConnection to include
3527 the hash function negotiated in the SKE protocol.
3529 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3530 to set the channel founder authentication data. A client can
3531 claim the founder rights later by providing the authentication
3532 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3533 This way the channel founder can regain the channel founder
3534 privileges even it is left the channel. This works only on
3535 local server and the client must be connected to the same
3536 server to be able to regain the founder rights. Updated the
3537 protocol specs accordingly.
3539 Added support to the CMODE command in the client to set the
3540 founder auth data. Read the README to see how to set it.
3542 Added support to the CUMODE command to claim the founder
3543 rights. Read the README to see how to do it.
3545 Added support for the founder authentication to the Channel
3546 Entry in the server. Affected file silcd/idlist.h.
3548 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3549 server's CMODE command. Affected file silcd/command.c.
3551 * Added the following new functions into lib/silccore/silcauth.[ch]:
3552 silc_auth_get_method and silc_auth_get_data.
3554 * The server now saves the remote hosts public key to the
3555 SilcIDListData pointer. Affected file silcd/protocol.c.
3557 * The normal server now does not remove the channel entry from
3558 the cache if the founder authentication data is set. It used
3559 to remove it if the founder was the last one on the channel on
3560 the server and left the channel. The auth data is saved and
3561 if the channel is re-joined later the old entry is used with
3562 the old auth data. Affected files silcd/command_reply.c and
3565 * Removed the `pkcs' field from the SilcIDListData structure
3566 in the server; it is not used. Affected file silcd/idlist.h.
3568 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Fixed packet processing on slow links. Partial packets were
3571 never re-processed because the incoming data buffer was cleared
3572 by the application. Application must not directly clear the
3573 sock->inbuf, the packet processing routines handle it. Fixed
3574 this in client library and in server.
3576 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Fixed the WHOIS and IDENTIFY send reply function to really
3579 check whether to send list or just one entry. Affected file
3582 * Cleaned up the LEAVE command's channel key distribution. The
3583 affected file silcd/command.c.
3585 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3586 can enforce the channel mode as well. In that case the ID
3587 includes the ID of the server. The code now enforces the
3588 mode change if the router have different mode than the server.
3590 * The notify client operation with CMODE_CHANGE notify can now
3591 return NULL client_entry pointer if the CMODE was not changed
3592 by client. Application must check for this.
3594 * Added <Server ID> argument to INFO command to support server
3595 info fetching by Server ID.
3597 * Added silc_server_announce_get_channel_users to get assembled
3598 packets of channel users of the specified channel. Affected
3599 file silcd/server.[ch].
3601 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3602 was freed underneath the ID Cache.
3604 * Re-announce clients when the server received CHANNEL_CHANGE
3605 notify from the router. Affected file silcd/packet_send.c.
3607 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3610 crashed since it did not handle the fact that there is no cipher
3611 called "3" and didn't check the error condition. Now fixed.
3613 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3614 flag. It can be used to send message requests.
3616 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Implemented the RESTART command in the client.
3620 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3621 notice type messages. Added notice printing to the user
3624 * The channel keys are not re-generated if the channel's mode
3625 is PRIVKEY, ie private key on the channel exists. Affected
3626 files silcd/server.c and silcd/command.c.
3628 * Fixed a little bug in channel message delivery when channel
3629 private keys are set in the server. Affected file is
3630 silcd/packet_send.c.
3632 * Changed the setting on channel->on_channel = TRUE from the
3633 silc_client_save_channel_key to the JOIN command reply. The
3634 key payload is not received if the private channel key is set.
3635 Affected file lib/silcclient/command_reply.c and the
3636 lib/silcclient/client_channel.c.
3638 * When the CMODE_CHANGE notify is sent and the channel private
3639 key mode is removed the channel key must be re-generated in
3640 other cells as well. Added this support for the router in the
3641 silcd/packet_receive.c.
3643 * Added new local command NOTICE to send notice message on
3644 channel. Affected file silc/local_command.[ch].
3646 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added new local command ME to the client. It is used to send
3649 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3650 some action. Affected file silc/local_command.[ch].
3652 * Changed channel_message and private_message client operations
3653 to deliver the message flags to the application. Added also
3654 the `flags' arguments to the silc_client_send_channel_message
3655 and silc_client_send_private_message functions. Affected file
3658 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Redefined the Private Message Payload to support private message
3661 keys and to support the new private message flags. Updated
3662 the protocol specs. Flags makes it possible to have for example
3663 CTCP style messages.
3665 * Added new type SilcPrivateMessagePayload and defined an API
3666 for it in the lib/silcclient/silcprivate.[ch].
3668 * Tested private message private keys successfully. Tested the
3669 private message key set, unset and list commands with the new
3672 * Redefined the Channel Message Payload to include the channel
3673 message flags (equal with private message flags) to support
3674 for example CTCP style messages.
3676 * Defined some of the message (for channel and private message)
3677 flags. Updated the protocol specs and added the flags to the
3678 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3680 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Added SilcKeyAgreementStatus type to the key agreement routines
3683 to indicate the current status and error if one occured.
3684 The status types are defined in the lib/silcclient/silcapi.h.
3686 * Added new local command KEY that is used to set and unset private
3687 keys for channels, set and unset private keys for private messages
3688 with remote clients and to send key agreement requests and
3689 negotiate the key agreement protocol with remote client. The
3690 key agreement is supported only to negotiate private message keys,
3691 it currently cannot be used to negotiate private keys for channels,
3692 as it is not convenient for that purpose.
3694 * Fixed a minor pending callback setting bug in the function
3695 silc_client_get_client_by_id_resolve, now the function works.
3696 Affected file lib/silcclient/idlist.c.
3698 * Added function silc_net_get_local_port to get local bound
3699 port by socket. Added to lib/silcutil/silcnet.[ch].
3701 * Added `sockets' and `sockets_count' fields to the SilcClient
3702 object. They hold the sockets of the listenning sockets in
3703 the client. Listenning sockets may be for example the key
3704 agreement server. Affected file lib/silcclient/client.[ch].
3705 Added functions the silc_client_add_socket and the
3706 silc_client_del_socket. They are exported to the application
3709 * Added ~./silc/clientkeys to support other client's public keys.
3711 * Renamed verify_server_key client operation to verify_public_key
3712 and added one argument to indicate the type of the connection
3713 (server, client etc.).
3715 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Added silc_server_connection_auth_request to handle the
3718 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3719 silcd/packet_receive.[ch].
3721 * Added silc_server_send_connection_auth_request into the
3722 silcd/packet_send.c to send the connection auth request packet.
3724 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3727 * Fixed the public key authentication in responder side in the
3728 server. The `auth_data' pointer includes the SilcPublicKey
3729 not the path to the public key. Affected file silcd/protocol.c.
3731 * Implemented the public key authentication in the initiator side
3732 in the server. Affected file silcd/protocol.c.
3734 * Removed the [RedirectClient] config section from the server
3735 configuration. Is not needed and I don't want to implement it.
3737 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Cleaned up the CMODE command in the server. It now works
3740 correctly and supports all the modes defined in the protocol.
3741 Affected file is silcd/command.c.
3743 * Added `hmac_name' field to the SilcChannelEntry in the server
3744 to hold the default HMAC of the channel. It can be set when
3745 creating the channel (with JOIN command). Affected files
3748 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3749 type to indicate the change of the current cipher and hmac
3750 on the channel. Client can safely ignore the <cipher> argument
3751 (if it chooses to do so) since the CHANNEL_KEY packet will
3752 force the channel key change anyway. The <hmac> argument is
3753 important since the client is responsible of setting the new
3754 HMAC and the hmac key into use.
3756 * Fixed the CMODE command in the client library as well.
3758 * Tested CMODE command in router environment successfully.
3760 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Show the version of the remote client (or server) when connecting
3763 to the server. It is logged to the log file. Affected file
3764 is silcd/protocol.c.
3766 * Fixed the KILLED notify handling in the client library. The
3767 client must be removed from all channels when receiving the
3770 Also, do not remove the client entry when giving the KILL
3771 command but when the KILLED notify is received.
3773 * Removed silc_idlist_find_client_by_nickname from the server.
3774 Not needed anymore. Affected files silcd/idlist.[ch].
3776 * Implemented the CHANNEL_CHANGE notify type handling to the
3777 server. Affected file silcd/server.c.
3781 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Added silc_server_send_notify_invite to send the INVITE
3784 notify between routers.
3786 * Implemented the INVITE command correctly to the server.
3788 * Implemented the INVITE notify type handling in the server.
3790 * Implemented the INVITE command to the client library and on the
3793 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Added function silc_server_get_client_resolve to find the
3796 client entry by ID from all ID lists and then resolve it
3797 (using WHOIS) if it cannot be found. Affected file is
3800 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Implemented the BAN command to the client library.
3804 * The JOIN command in the server now checks the invite list
3807 * Changed the silc_command_reply_payload_encode_va and the
3808 silc_command_payload_encode_va to support that if argument is
3809 NULL it ignores and checks the next argument. Affected file
3810 lib/silccore/silccommand.c.
3812 * Added silc_server_send_notify_ban to send the BAN notify
3813 type between routers.
3815 * Chaned the silc_notify_payload_encode to support that if
3816 argument is NULL it ignores and checks the next argument.
3817 Affected file lib/silccore/silcnotify.c.
3819 * Tested ban lists in router environment successfully.
3821 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Implemented BAN command to the server, in silcd/command.[ch].
3825 * Removed the BAN and INVITE_LIST modes from the CMODE command
3828 * Added function silc_string_match to regex match two strings.
3829 Affected files lib/silcutil/silcutil.[ch].
3831 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Redefined parts of the SilcChannelEntry in the server to support
3834 the new ban and invite lists.
3836 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * Redefined the INVITE command. The same command can be used to
3839 invite individuals to the channel but also to manage the invite
3840 list of the channel (to add to and remove from the invite list).
3841 Updated the protocol specs.
3843 * Added new command SILC_COMMAND_BAN that can be used to manage
3844 the ban list of the channel. Updated the protocol specs.
3846 * Removed the channel modes: the SILC_CMODE_BAN and the
3847 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3848 in the CMODE command. The equivalent features are now available
3849 using INVITE and BAN commands. Updated the protocol specs.
3851 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3852 in the network about change in the current ban list. The notify
3853 type is not used by the client.
3855 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3856 support the invite lists.
3858 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added new function silc_string_regexify that converts string
3861 including wildcard characters into regex string that can
3862 be used by the GNU regex library. Added into the file
3863 lib/silcutil/silcutil.[ch].
3865 Added silc_string_regex_combine to combine to regex strings
3866 into one so that they can be used as one regex string by
3867 the GNU regex library. Added into the file
3868 lib/silcutil/silcutil.[ch].
3870 Added silc_string_regex_match to match two strings. It returns
3871 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3873 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Imported GNU regex to the soruce tree into lib/contrib.
3876 Fixed some compiler warning from the regex.c.
3878 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Fixed MOTD command in the server to work in router environment.
3882 * Fixed the MOTD command in the client library to support
3883 the server argument in the command.
3885 * Added `nickname_len' argument to the silc_idlist_add_client
3886 in the server, as the `nickname' argument may be binary data
3889 * Added silc_idlist_get_channels to return all channels from
3892 * Implemented LIST command to the server. Affected file is
3895 * Implemented the LIST command to the client library and on the
3898 * Added [<user count>] argument to the LIST command reply.
3899 With private channels the user count is not shown.
3901 * Updated TODO and README.
3903 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * The client entry's data.registered must be TRUE even with
3906 global client entry on global client list. The data.registered
3907 is used to check whether the client is anymore in the network,
3908 for example with WHOWAS command so it must be valid.
3910 * Fixed the WHOWAS command in the server. It now actually works
3911 in router environment. Added function into silcd/command_reply.c
3912 silc_server_command_reply_whowas_save.
3914 * Added silc_idlist_purge function to the silcd/idlist.c
3915 to periodically purge the ID Cache.
3917 * Fixed INFO command in the server. It works now in router
3918 environment. Added <server name> argument to the INFO command
3919 reply. Updated the protocol specs.
3921 * Fixed minor bug in silc_idcache_purge to not purge if the
3922 expire value is zero.
3924 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3925 they were buggy because of the WHOWAS information.
3927 * Fixed local command MSG to handle the async resolving of
3928 the remote client properly. It used to fail the first MSG.
3929 Affected file silc/local_command.c.
3931 * Added `data_len' field to SilcIDCache context.
3933 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Update TODO. Todo in commands in the server.
3937 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3940 used by routers as broadcast packet to inform other routers
3941 about the changed user mode.
3943 Implemented the notify handling in the server. Affected file is
3944 silcd/packet_receive.c. Added the function
3945 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3947 * Added new generic Channel Payload and deprecated the New Channel
3948 Payload. The New Channel Payload is now the generic Channel
3951 * Added new argument `mode' to the silc_server_send_new_channel
3952 as it is required in the Channel Payload now.
3954 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3955 and created a new and real SilChannelPayload to represent the
3956 new generic Channel Payload. Implemented the encode/decode
3957 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3959 * Added silc_server_get_client_channel_list to return the list
3960 of channels the client has joined for WHOIS command reply.
3961 Affected file silcd/server.[ch].
3963 * Implemented the channel list sending in the WHOIS command reply
3964 in server and in the client.
3966 Implemented the channel list displaying on the user interface
3967 as well. Affected file silc/client_ops.c.
3969 * Added silc_channel_payload_parse_list to parse list of Channel
3970 Payloads. It returns SilcDList list of SilcChannelPayloads.
3971 Client for example can use this function to parse the list of
3972 channels it receives in the WHOIS command reply. The caller
3973 must free the list by calling silc_channel_payload_list_free.
3974 Affected files lib/silccore/silcchannel.[ch].
3976 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Added one new argument <user mode> to the WHOIS command reply
3979 to return the mode of the user in SILC. Updated the protocol
3982 Implemented it to the server and client.
3984 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Fixed the mode printing on the user interface on joining.
3987 Affected file silc/client_ops.c.
3989 * Implemented the UMODE command and user modes in general to the
3990 client library and to the user interface.
3992 * Implemented the UMODE command to the server.
3994 * The server now sends UNKNOWN_COMMAND error status if client sends
3995 unknown command. Affected file silcd/command.c.
3997 * All server commands now handle the command identifier the right
3998 way when sending the command reply to the client. The client can
3999 use to identify the command replies with the identifier.
4001 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Added silc_server_get_client_route to resolve the route to
4004 the client indicated by the client ID. Affected file is
4007 * Added silc_server_relay_packet as general function to relay
4008 packet to arbitrary destination. This deprecates functions
4009 like _send_private_message_key, _relay_notify etc. Affected
4010 file is silcd/packet_send.[ch].
4012 Removed silc_server_send_key_agreement,
4013 silc_server_send_private_message_key and
4014 silc_server_packet_relay_notify functions from the file
4015 silcd/packet_send.[ch].
4019 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4020 server. Affected file silcd/packet_receive.[ch].
4022 * Implemented the KILL command to the client. Implemented the
4023 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4024 Affected files lib/silcclient/command[_reply].c and
4025 lib/silcclient/client_notify.c. Implemented the KILL notify
4026 printing in the user inteface.
4028 * Fixed a lot silc_parse_nick memory leaks from the client
4029 library in the file lib/silcclient/command.c.
4031 * Changed the silc_server_send_notify_on_channels's `sender'
4032 argument from SilcSocketConnection to SilcClientEntry to
4033 check the sender as entry and not as connection object and not
4034 to send to the client provided as argument. The affected file
4035 is silcd/packet_send.[ch].
4037 * The notify packets that are destined directly to the client used
4038 to not to be processed by the server. Now changed that and the
4039 server processes all notify packets. After relaying the packet
4040 to the client the notify packet is processed in the server.
4042 * The silc_server_free_client_data now checks whether there is
4043 pending outgoing traffic for the client and purges the data to
4044 the network before removing the client entry.
4046 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4049 an client is killed from the SILC Network. Updated the protocol
4052 Added new function silc_server_send_notify_killed to the
4053 silcd/packet_send.[ch].
4055 * Added function silc_server_packet_relay_notify to relay notify
4056 packets that are destined directly to a client. In this case
4057 the server does not process the notify packets but merely relays
4058 it to the client. Affected file silcd/packet_send.[ch].
4060 Added also silc_server_packet_process_relay_notify to check
4061 whereto relay the notify. Affected file is
4062 silcd/packet_receive.[ch].
4064 * Implemented the KILL command to the server.
4068 * Added the backup schema desgined last fall to the protocol
4069 specs for everyone to see. The specification is in the
4070 *-spec-xx.txt draft and the packet type definitions for the
4071 backup routers is in *-pp-xx.txt draft. Thusly, added also
4072 new packet type SILC_PACKET_CELL_ROUTERS.
4074 * A big security problem in the implementation discovered. The
4075 signoff of an client did not cause new channel key generation
4076 which it of course should've done. The channel keys must be
4077 always re-generated when client leaves (or signoffs) the channel.
4078 The silc_server_remove_from_channels funtion now handles
4079 the channel key re-generation.
4081 * Added `sender' argument to the silc_server_send_notify_on_channels
4082 to not to send the client provided as argument. Affected file
4083 silcd/packet_send.[ch].
4085 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Implemented OPER and SILCOPER commands into the server and
4090 * Added silc_auth_verify and silc_auth_verify_data to verify
4091 the authentication directly from the authentication payload.
4092 It supports verifying both passphrase and public key based
4093 authentication. Affected file lib/silccore/silcauth.[ch].
4095 * Added `hash' field to the SilcIDListData structure. It is the
4096 hash negotiated in the SKE protocol. Affected file is
4099 * Slight redesigning of the SilcAuthPayload handling routines.
4100 Do not send SilcPKCS but SilcPublicKey as argument.
4102 * Implemented the public key authentication support to the
4103 serverconfig. The public key is loaded from the provided path
4104 and saved as authentication data to void * pointer. Thus,
4105 changed the unsigned char *auth_data to void *auth_data;
4107 * Fixed SHUTDOWN command to send the reply before the server
4108 is shutdown. :) Affected file silcd/command.c.
4110 * Fixed fatal bug in CONNECT command. The hostname was invalid
4111 memory and server crashed. Affected file silcd/command.c.
4113 * Fixed fatal bug in CLOSE command. The server_entry became
4114 invalid but was referenced later in the command. Affected file
4117 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Fixed fatal bug in failure packet handling. Server ignored
4120 the failure and thus crashed when it came.
4124 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4127 that the command may be executed only once in (about) 2 seconds.
4128 The old SILC_CF_LAG flag is same but allows command bursts up
4129 to five before limiting.
4131 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4132 server code. Various commands now includes the CF_LAG_STRICT
4133 flag to disallow any kind of miss-use of the command.
4135 * Fixed the silc_buffer_unformat to not to allocate any data
4136 if the length of the data is zero. It used to allocate the
4137 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4139 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Changed the format of AdminConnection configuration section
4142 in the server. Added username of the admin to the format.
4143 Affected files silcd/serverconfig.[ch].
4145 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4146 to return admin configuration data by host, username and/or
4149 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Implemented WHOWAS command to the server. Added the functions:
4153 silc_server_command_whowas_parse,
4154 silc_server_command_whowas_send_reply,
4155 silc_server_command_whowas_from_client and
4156 silc_server_command_whowas_from_server
4158 * Added <Client ID> argument to the WHOWAS command reply. Updated
4159 the protocol specs accordingly.
4161 * Implemented WHOWAS command and command_reply to the client
4164 Implemented the WHOWAS printing on the user interface.
4166 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Added new argument to the WHOWAS command reply, the real name.
4169 It is an optional argument. Updated the protocol specs.
4171 * Added SilcIDCacheDestructor callback that is registered when
4172 the SilcIDCache is allocated. The callback is called when
4173 an cache entry in the ID Cache expires, or is purged from the
4174 cache. Added into lib/silccore/idcache.[ch].
4176 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4177 to destruct the client entries when the cache entry expires.
4178 Other ID Cache's in server and in the client library ignores
4181 * If the ID Cache entry's `expire' field is zero then the entry
4182 never expires. Added boolean `expire' argument to the
4183 silc_idcache_add function in the lib/silccore/idcache.[ch].
4184 If it is TRUE the default expiry value is used.
4186 * Added silc_server_free_client_data_timeout that is registered
4187 when client disconnects. By default for 5 minutes we preserve
4188 the client entry for history - for WHOWAS command.
4190 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Added support to the server to enforce that commands are not
4193 executed more than once in 2 seconds. If server receives
4194 commands from client more frequently, timeout is registered
4195 to process the commands. Affected file silcd/command.c.
4196 Added new function silc_server_command_process_timeout.
4198 * Changed NICK_NOTIFY handling in client library to check that
4199 if the client's nickname was changed, so there is no need to
4200 resolve anything from the server.
4202 * Removed error printing from the WHOIS and IDENTIFY commands.
4203 If error occurs then it is ignored silently in the client library.
4204 The application, however, may map the received error to
4205 human readable error string. The application currently maps
4206 the NO_SUCH_NICKNAME error to string.
4208 * Made the command status message public to the application. Moved
4209 them from lib/silcclient/command_reply.c to
4210 lib/silcclient/command_reply.h. The application can map the
4211 received command status to the string with the
4212 silc_client_command_status_message function.
4214 * Added check to the server to check that client's ID is same
4215 as the Source ID in the packet the client sent. They must
4218 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Added dist-bzip hook to the Makefile.am to make bzip2
4221 compressed distributions.
4223 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Server now enforces the maximum length for the nickname and
4226 the channel as protocol specification dictates. 128 bytes for
4227 nickname and 256 bytes for channel name.
4229 * Moved the WHOIS printing to the application. The client libary
4230 does not print out the WHOIS information anymore, the application
4231 must do it. Renamed silc_client_command_reply_whois_print to
4232 the silc_client_command_reply_whois_save.
4234 The client's idle time is also sent to the application now, and
4235 the idle is shown on screen.
4237 * Added silc_client_command_reply_identify_save to save the
4238 received IDENTIFY entries.
4240 * Do not check for channel private keys in message sending and
4241 reception if the channel does not have the PRIVKEY mode set.
4242 Affected file lib/silclient/client_channel.c.
4244 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4247 just surfaced after chaning the JOIN procedure.
4249 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added silc_client_get_clients_by_list to get client entries
4252 from Client ID list, that is returned for example by JOIN
4253 and USERS command replies. The application should use this
4254 function for example when JOIN command reply is received to
4255 resolve the clients already on the channel (library does not
4256 do that anymore as USERS command reply is not used in the JOIN
4257 procedure anymore). Affected files lib/silcclient/silcapi.h and
4258 lib/silcclient/idlist.c.
4260 * JOIN command reply and USERS command reply returns now SilcBuffer
4261 pointers instead of unsigned char pointers when returning
4262 the client list and mode list.
4264 * Added <Client ID> argument to the JOIN command reply, mainly
4265 for the server to identify for which client the command was
4266 originally sent. Updated protocol specs accordingly.
4268 * Added SilcDlist private_key pointer to the SilcChannelEntry
4269 in the client to support the channel private keys. Affected
4270 file is lib/silcclient/idlist.h.
4272 * Added SilcChannelPrivateKey argument to the function
4273 silc_client_send_channel_message so that application can choose
4274 to use specific private ke if it wants to. If it is not provided,
4275 the normal channel key is used, unless private keys are set.
4276 In this case the first (key that was added first) is used
4277 as the encryption key.
4279 * Implemented the support for channel private key handling.
4280 Implemented the following functions:
4282 silc_client_add_channel_private_key,
4283 silc_client_del_channel_private_keys,
4284 silc_client_del_channel_private_key,
4285 silc_client_list_channel_private_keys and
4286 silc_client_free_channel_private_keys
4288 Affected file lib/silcclient/client_channel.c.
4290 * Added the support for the private keys in the channel message
4291 sending and encryption and in the message reception and
4292 decryption. Affected funtions are
4293 silc_client_send_channel_message and silc_client_channel_message.
4295 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Added SKE's key verify callback to the client library's
4298 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4300 * Removed the statement that server (or router) must send USERS
4301 command reply when joining to the channel so that the client
4302 knows who are on the channel. Instead, the client list and
4303 client's mode list is now sent in the JOIN command reply to the
4304 client who joined channel. This is better solution.
4306 * Added function silc_server_get_users_on_channel and function
4307 silc_server_save_users_on_channel to the silcd/server.[ch].
4309 * Removed function silc_server_command_send_users from the
4312 * Do not show topic on the client library anymore. The topic is
4313 sent in the command reply notify to the application and the
4314 application must show the topic now.
4316 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Added client searching by nickname hash into the IDENTIFY and
4319 WHOIS commands in the server as they were clearly missing from
4320 them. Affected file is silcd/command.c.
4322 * Fixed a bug in private message receiving in the client library.
4323 The remote ID was freed and it wasn't supposed, now it is
4326 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Minor fix to the channel payload; allocate the data area, as it
4329 needs to be of specific length.
4331 * If the key agreement port is zero then the operating
4332 system will define the bound port. Affected files are
4333 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4335 * Added new function silc_channel_payload_decrypt into the file
4336 lib/silccore/silcchannel.[ch].
4338 * Moved the channel message etc, check from silc_packet_decrypt
4339 to applications. The library calls now a generic
4340 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4341 when the packet is either normal or special. This was done to
4342 allow more wide range of checking that was not allowed when
4343 the code was in library. Now applications can do virtually any
4344 checks to the packet and return to the library the decision how
4345 the packet should be processed. Affected files are
4346 lib/silccore/silcpacket.[ch].
4348 Added silc_server_packet_decrypt_check to the server and
4349 silc_client_packet_decrypt_check to the client library.
4351 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4352 to send with specified source and destination information.
4354 * Channel message delivery between routers was broken after the
4355 channel key distribution was fixed earlier. The channel key
4356 was used be to distributed to other routers as well which is not
4357 allowed by the protocol. Now this is fixed and channel keys
4358 really are cell specific and the channel message delivery between
4359 routers comply with the protocol specification.
4361 * Fixed various commands in server to check also the global list
4362 for the channel entry and not just the local list. The affected
4363 file silcd/command.c.
4365 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Added assert()s to buffer formatting and unformatting routines
4368 to assert (if --enable-debug) when error occurs. Affected
4369 file: lib/silcutil/silcbuffmt.c.
4371 * Changed to auto-reconnect to check whether the remote host is
4372 router and register the re-connect timeout if it is. It used
4373 to check that whether we are normal server, but router must do
4374 auto-reconnect with another router as well. Affected file
4377 * Removed the [<key len>] option from CMODE command as the cipher
4378 name decides the key length, nowadays. See the defined ciphers
4379 from the protocol specification.
4381 * Added [<hmac>] option to the CMODE command to define the HMAC
4382 for the channel. Added SILC_CMODE_HMAC channel mode.
4384 * Added [<hmac>] option for the JOIN command so that user can
4385 select which HMAC is used to compute the MACs of the channel
4388 * Added Hmac field to the Channel Message Payload. The integrity
4389 of plaintext channel messages are now protected by computing
4390 MAC of the message and attaching the MAC to the payload. The
4391 MAC is encrypted. Now, it is clear that this causes some
4392 overhead to the size of the packet but rationale for this is that
4393 now the receiver can verify whether the channel message decrypted
4394 correctly and also when private keys are set for the channel the
4395 receiver can decrypt the packet with several keys and check from
4396 the MAC which key decrypted the message correctly.
4398 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4399 lib/silccrypt/silccipher.[ch].
4401 * Added silc_hash_len to return the digest length into the
4402 lib/silcrypt/silchash.[ch].
4404 * Rewrote parts of Silc Channel Payload interface in the
4405 lib/silccore/silcchannel.[ch]. The encode function now also
4406 encrypts the packet and parse function decrypts it.
4408 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Fixed a minor formatting bug in the SKE's key material processing.
4411 It actually might have processed the keys wrong way resulting
4414 * Redefined the mandatory HMAC algorithms and added new algorithms.
4415 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4416 and hmac-md5 truncated to 96 bits. The mandatory is now
4417 hmac-sha1-96. Rest are optional (including the one that used
4418 to be mandatory). Rationale for this is that the truncated HMAC
4419 length is sufficient from security point of view and can actually
4420 make the attack against the HMAC harder. Also, the truncated
4421 HMAC causes less overhead to the packets. See the RFC2104 for
4424 * Added new [hmac] configuration section. The SKE used to use
4425 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4426 is of course wrong. The official names that must be proposed in
4427 the SKE are the ones defined in the protocol specification
4428 (hmac-sha1-96 for example). The user can configure any hmac
4429 using any hash function configured in the [hash] section. At
4430 least, the mandatory must be configured.
4432 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4434 * Added HMAC list to the SKE proposal list. It has now both
4435 hash algorithm list and HMAC list. This makes the protocol
4436 incompatible with previous versions. The SKE now seems to work
4437 the way it is supposed to work, for the first time actually.
4439 * Defined plain Hash algorithms to the protocol specification.
4442 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Implemented support for key agreement packets into the server.
4445 Added functions silc_server_key_agreement and
4446 silc_server_send_key_agreement. Other than these functions,
4447 server has nothing to do with this packet.
4449 * Added support for private message key packets into the server.
4450 Added functions silc_server_private_message_key and
4451 silc_server_send_private_message_key.
4455 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4456 called in the protocol's final callback instead in the END
4457 protocol state. This makes a little more sense and in the same
4458 time in client we can use the same protocol routines for normal
4459 key exchange and to key agreement packet handling as well.
4461 * Added to both client's and server's KE protocol context the
4462 SilcSKEKeyMaterial pointer to save the key material. We will
4463 bring the key material to the protocol's final callback by doing
4464 this. The final callback must free the key material.
4466 * Added SKE's packet_send callback into client's KE protocol
4467 context so that the caller can choose what packet sending function
4468 is used. This way we can use different packet sending when
4469 doing normal SKE when doing key agreement packet handling (in
4470 the key agreement packet handling we do not want to encrypt
4473 * Implemented the responder side of the key agreement routines
4474 in the client. The client can now bind to specified port and
4475 accept incoming key negotiation. The key material is passed
4476 to the application after the protocol is over.
4478 * Implemented the processing of incoming Key Agreement packet
4479 in the client. Added function silc_client_key_agreement to
4482 * Implemented the intiator side of the key agreement routines
4483 in the client. The client can now initiate key agreement with
4484 another remote client. The key material is passed to the
4485 application after the protocol is over.
4487 * Created client_keyagr.c to include all the key agreement
4490 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4491 SILC_TASK_CALLBACK except that it is not static.
4493 * Created client_notify.c and moved the Notify packet handling
4494 from the client.[ch] into that file.
4496 * Created client_prvmsg.c and moved all private message and
4497 private message key routines from the client.[ch] into that file.
4499 * Create client_channel.c and moved all channel message and
4500 channel private key routines from the client.[ch] into that file.
4502 * Changed silc_client_get_client_by_id_resolve to resolve with
4503 WHOIS command instead of IDENTIFY command, in the file
4504 lib/silclient/idlist.c.
4506 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Implemented the SKE's responder side to the Client library.
4510 * When FAILURE is received to the protocol do not trust it
4511 blindly. Register a timeout to wait whether the remote closes
4512 the connection as it should do it, only after that process the
4513 actual failure. This was changed to both client and server.
4515 * Added client_internal.h to include some of the structures
4516 there instead of client.h in lib/silcclient/.
4518 * Added function silc_task_unregister_by_callback to unregister
4519 timeouts by the callback function.
4521 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Some "Incomplete WHOIS info" errors has been appearing on the
4524 log files. Took away the entry->userinfo check from WHOIS
4525 reply sending. The entry->userinfo is now " " if client did not
4526 provide one. I thought this was fixed earlier but something
4527 is wrong still. Let's see if the error still appears.
4529 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Fixed a minor bug in the login when the channel key is
4532 re-generated in the server. It used to generate the key in
4533 wrong order and thus caused problems in the channel traffic.
4535 * Fixed a minor bug in channel key distsribution after
4536 KICK command. The key was not sent to the router even though
4539 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Added silc_ske_process_key_material_data as generic routine
4542 to process any key material as the SILC protocol dictates. The
4543 function is used by the actual SKE library but can be used by
4544 applications as well. This relates to the private message keys
4545 and the channel private keys since they must be processed the
4546 same way the normal SILC session keys. The protocol dictates
4547 this. Affected files: lib/silcske/silcske.[ch].
4549 Added also silc_ske_free_key_material to free the
4550 SilcSKEKeyMaterial structure.
4552 * Defined silc_cipher_set_key function to set the key for
4553 cipher without using the object's method function. The affected
4554 files: lib/silccrypt/silccipher.[ch].
4556 * Implemented silc silc_client_add_private_message_key,
4557 silc_client_add_private_message_key_ske,
4558 silc_client_del_private_message_key,
4559 silc_client_list_private_message_keys and
4560 silc_client_free_private_message_keys functions in the
4563 Added functions silc_client_send_private_message_key to send
4564 the Private Message Key payload and silc_client_private_message_key
4565 to handle incoming Private Message Key payload.
4567 * Added Cipher field to the Private Message Key payload to set
4568 the cipher to be used. If ignored, the default cipher defined
4569 in the SILC protocol (aes-256-cbc) is used.
4571 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Removed lib/silcclient/ops.h file.
4575 Redefined parts of the SILC Client Library API. Created new
4576 file silcapi.h that deprecates the ops.h file and defines the
4577 published Client Library API. Defined also private message key
4578 API and channel private key API into the file.
4580 This is the file that the application must include from the
4581 SILC Client Library. Other files need not be included by
4582 the application anymore.
4584 * Added new key_agreement client operation callback and also
4585 defined the Key Agreement library API for the application.
4587 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4590 is used by clients to request key negotiation between another
4591 client in the SILC network. If the negotiation is started it
4592 is performed using the SKE protocol. The result of the
4593 negotiation, the secret key material, can be used for example
4594 as private message key.
4596 Implemented the Key Agreement payload into the files
4597 lib/silccore/silauth.[ch].
4599 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Redefined ciphers for the SILC protocol. Added some new ciphers
4602 and defined the key lengths for the algorithms. Changed the
4603 code accordingly. The default key length is now 256 bits.
4605 * Fixed SKE key distribution function silc_ske_process_key_material
4606 when the key length is more than 128 bits. The default key
4607 length in SILC is now 256 bits.
4609 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4610 to indicate unsupported algorithm.
4612 * Renamed rijndael.c to aes.c and all functions as well.
4614 * Fixed a long standing channel key setting bug in client library.
4615 Weird that it has never surfaced before.
4617 * Fixed bug in channel deletion. If the entire channel is removed
4618 then it must also delete the references of the channel entry
4619 from the client's channel list as the client's channel entry and
4620 the channel's client entry share same memory.
4622 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Implemented CONNECT and SHUTDOWN commands in the client.
4626 * Implemented CLOSE command to the client.
4628 * Added the function silc_idlist_find_server_by_name into the
4629 files silcd/idlist.[ch].
4631 Added the function silc_idlist_find_server_by_conn into the
4632 files silcd/idlist.[ch].
4634 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * DIE command was renamed to SHUTDOWN. Updated the both code
4639 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4640 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4642 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4645 * Added function silc_server_create_connection function to create
4646 connection to remote router. My server implementation actually
4647 does not allow router to connect to normal server (it expects
4648 that normal server always initiates the connection to the router)
4649 so the CONNECT command is only good for connecting to another
4652 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4655 or some other client was kicked from the channel.
4657 Implemented the handling of the notify type to both client
4660 Implemented silc_server_send_notify_kicked to send the KICKED
4661 notify. It is used to send it to the server's primary router.
4663 * Implemented the KICK command into server and client.
4665 * Added `query' argument to the silc_idlist_get_client function
4666 to indicate whether to query the client from server or not if
4669 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4670 to indicate that the client is not channel founder.
4674 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Removed the rng context from SilcPacketContext structure and
4677 changed that the packet routine uses the Global RNG API.
4679 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Added support for quit message that client can "leave" on the
4682 channel when it quits the SILC. It is ditributed inside the
4683 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4685 Added silc_server_free_client_data that will take the
4686 signoff message as argument.
4688 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4690 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Updated parts of the protocol specification to keep it up
4695 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4698 payloads in one packet.
4700 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4701 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4702 use now the new List flag.
4704 * Also deprecated the following packet types: REPLACE_ID,
4705 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4707 * Added list support for Notify packet in server.
4709 * Added silc_server_send_notify_channel_change to send the
4710 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4711 the silc_server_send_replace_id.
4713 * Added silc_server_send_notify_nick_change to send the
4714 NICK_CHANGE notify type. Deprecates the function
4715 silc_server_send_replace_id.
4717 * Added silc_server_send_notify_join to send the JOIN notify type.
4718 Deprecates the function silc_server_send_new_channel_user.
4720 * Added silc_server_send_notify_leave to send LEAVE notify type.
4721 Deprecates the function silc_server_send_remove_channel_user.
4723 * Added silc_server_send_notify_cmode and
4724 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4725 types. Deprecates the silc_server_send_set_mode function.
4727 * Added SERVER_SIGNOFF notify type to indicate that server has
4728 quit. This means that all clients on the channel from that
4729 server will drop. This can be also used when netsplit happens.
4731 Deprecated REMOVE_ID packet type since it is not needed anymore
4734 Added silc_server_send_notify_server_signoff to send the
4735 SERVER_SIGNOFF notify type. Deprecates the function
4736 silc_server_send_remove_id.
4738 Added also silc_server_send_notify_signoff to send the
4739 SIGNOFF notify type.
4741 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4742 SILC protocol from this day on. Changed the protocol
4743 specification as well.
4745 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4746 notify type. It is used between routers to notify about
4747 topic changes on a channel.
4749 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4752 * Partly updated the protocol specification to comply with the
4753 changes now made. It is still though a bit outdated.
4755 * The JOIN notify type now takes one extra argument <Channel ID>.
4756 The packet used to be destined to the channel but now the
4757 JOIN type may be sent as list thus it is impossible to
4758 destine it to any specific channel. By adding this argument
4759 it is again possible.
4761 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Added CREDITS file. The CHANGES and CREDITS file will appear
4764 in the distribution as well.
4766 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4769 types in the server's silcd/packet_receive.c.
4771 * Implemented CMODE and CUMODE to work in router environment.
4773 * Fixed minor encoding and decoding buglet from the
4774 lib/silccore/silcmode.c.
4776 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4779 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4781 * Changed all SilcConfigServer* and silc_config_server* to
4782 SilcServerConfig* and silc_server_config*, respectively.
4785 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Associated the ID (client or server ID) to the Authentication
4788 Payload to avoid any possibility of forging. Updated the
4789 protocol specification and the code accordingly.
4791 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * The RSA key length is now save to the RsaKey context in the
4794 key generation process in lib/silccrypt/rsa.c. The key length
4795 is now used to figure out the maximum size of the block allowed
4796 to be encrypted/signed.
4798 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4799 is equivalent to the silc_mp_mp2bin but does not allocate any
4802 * Changed silc_mp_mp2bin API to take length argument. If it is
4803 non-zero then the buffer is allocated that large. If zero, then
4804 the size is approximated using silc_mp_sizeinbase, which however
4807 * Created Global RNG API which is global RNG that application can
4808 initialize. After initializing, any routine anywhere in the
4809 code (including library) can use RNG without allocating a new
4810 RNG object. This was done to allow this sort of use of the
4811 RNG in code that has no chance to allocate RNG object. All
4812 applications currently allocate this and many routines in the
4813 library use this. Affected file lib/silccrypt/silcrng.[ch].
4815 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4816 it to use the Global RNG API.
4818 * Defined Authentication Payload into protocol specification that
4819 is used during SILC session to authenticate entities. It is
4820 used for example by client to authenticate itself to the server
4821 to obtain server operator privileges.
4823 Implemented this payload into the lib/silccore/silcauth.[ch].
4824 Implemented also routines for public key based authentication
4825 as the new protocol specification dictates.
4827 Moved definitions of different authentication methods from
4828 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4830 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4831 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4832 silc_pkcs_verify_with_hash functions into the file
4833 lib/silccrypt/silcpkcs.[ch].
4835 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * The client entry's userinfo pointer must be always valid.
4838 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4839 will fail since it requires the userinfo. Now, the userinfo
4840 is allocated as "" if actual userinfo does not exist. Actually,
4841 it must exist and it is totally Ok to drop client connections
4842 that does not announce the userinfo. However, we will make
4843 this workaround for now.
4845 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4846 to return the remote port by socket.
4848 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4851 SILC_SERVER_PENDING_EXEC and added an new macro
4852 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4853 data or when error occurs while processing the pending command.
4855 Added new argument `destructor' into silc_server_command_pending
4856 and to the SilcServerCommandPending object. This destructor is
4857 now called after calling the pending callback or if error occurs
4858 immediately. If error occurs the actual pending callback won't
4859 be called at all - only the destructor. The destructor may be
4860 NULL if destructor is not needed.
4862 All this applies for client library code as well. Similar
4863 changes were made there as well for the pending commands.
4865 In the client, the application must now allocate the
4866 SilcClientCommandContext with the silc_client_command_alloc
4869 * Added reference counter to the SilcServerCommandContext. Added
4870 function silc_server_command_alloc and silc_server_command_dup
4873 Same type of functions added to the client library for the same
4876 * Removed the cmd_ident from IDListData away since it is now
4877 global for all connections. It is the command identifier used
4878 in command sending and with pending commands. The affected file
4881 * Added reference counter to the SilcSocketConnection objecet to
4882 indicate the usage count of the object. The object won't be
4883 freed untill the reference counter hits zero. Currently only
4884 server uses this, and client ignores it. The client must be
4885 set to use this too later. The affected files are
4886 lib/silccore/silcsockconn.[ch]. Added also the function
4887 silc_socket_dup to increase the reference counter.
4889 This was mainly added because it is possible that the socket
4890 is removed underneath of pending command or other async
4891 operation. Now it won't be free'd and proper DISCONNECTING
4892 flags, etc. can be set to avoid sending data to connection that
4893 is not valid anymore.
4895 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4896 the connection. After that it sets SILC_SET_DISCONNECTED.
4897 It is, however, possible that the socket data is not still freed.
4898 The silc_server_packet_process now checks that data is not
4899 read or written to connection that is DISCONNECTED. The socket
4900 get's freed when the reference counter hits zero.
4902 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Changed the client operation API: channel_message operation's
4905 `sender' is now the client entry of the sender, not the nickname
4906 and the `channel' is the channel entry, not the channel name.
4908 In the private_message operation the `sender' is now also the
4909 client entry of the sender not the nickname.
4911 Affected file is lib/silcclient/ops.h and all applications
4912 using the client operations.
4914 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Moved the calling of ops->connect() from connect_to_server_final
4917 into receive_new_id functin since that is the point when the
4918 client is actually allowed to send traffic to network. The
4919 affected file is lib/silcclient/client.c.
4921 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4924 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4925 (if needs broadcasting) instead of broadcasting the packets one
4926 by one which would make a burst in the network traffic.
4928 * Added `broadcast' argument to the functions in silcd/server.[ch]
4929 silc_server_create_new_channel[_with_id] to indicate whether
4930 to send New Channel packet to primary router.
4932 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Added new function into the silcd/server.[ch] files:
4935 silc_server_create_new_channel_with_id to create new channel with
4936 already existing Channel ID.
4938 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4939 lib/silccore/silcpacket.h. This packet is used t send list of
4940 Set Mode payloads inside one packet. Server uses this to set
4941 the modes for the channels and clients on those channels, that it
4942 announced to the router when it connected to it. The protocol
4943 specification has been updated accordingly.
4945 * The silc_server_new_channel did not handle the packet coming
4946 from normal server as it normally does not send that. However,
4947 when it announces its channels it does send it. Implemented
4948 the support for that.
4950 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4951 into the file lib/silccore/id.h.
4953 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Fixed memory leaks in the functions silc_idlist_del_client,
4956 silc_idlist_del_channel and silc_idlist_del_server in the file
4957 silcd/idlist.c. All of those leaked like a sieve.
4959 * Fixed some small memory leaks in the client's function
4960 silc_client_notify_by_server.
4962 * Added functions into silcd/server.c: silc_server_announce_clients,
4963 silc_server_announce_channels and silc_server_announce_server.
4964 These functions are used by normal and router server to announce
4965 to its primary router about clients, channels and servers (when
4966 router) that we own. This is done after we've connected to the
4969 These functions effectively implements the following packet types:
4970 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4971 and SILC_PACKET_NEW_ID_LIST.
4973 * Added new functions into the silcd/packet_receive.[ch]:
4974 silc_server_new_id_list, silc_server_new_channel_list and
4975 silc_server_new_channel_user_list to handle the incoming
4976 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4978 * Added support of changing Channel ID in the function
4979 silc_server_replace_id. If the server that announces a channel
4980 to the router already exists in the router (with same name but
4981 with different Channel ID), router is responsible to send
4982 Replace ID packet to the server and force the server to change
4983 the Channel ID to the one router has.
4985 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4986 client that the Channel ID has been changed by the router. The
4987 normal server sends this to the client. Client must start using
4988 the new Channel ID as the channel's ID.
4990 Implemented handling of this new type into lib/silcclient/client.c
4991 into the function silc_client_notify_by_server.
4993 * Added new function silc_idlist_replace_channel_id into the files
4994 silcd/idlist.[ch] to replace the Channel ID.
4996 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Call silc_server_command_identify_check always when processing
4999 the IDENTIFY command in silcd/command.c
5001 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5004 send keepalive packets. The packet can be sent by clients,
5005 servers and routers.
5007 Added function silc_socket_set_heartbeat into the file
5008 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5009 If not set, the heartbeat is not performed. The actual
5010 heartbeat is implemented in the low level socket connection
5011 library. However, application is responsible of actually
5014 Added silc_server_send_heartbeat to send the actual heartbeat
5015 packet into silcd/packet_send.[ch]. Server now performs
5016 keepalive with all connections.
5018 * Added silc_task_get_first function into lib/silcutil/silctask.c
5019 to return the timeout task with shortest timeout. There was a bug
5020 in task unregistration that caused problems. TODO has been
5021 updated to include that task system must be rewritten.
5023 * The client library will now resolve the client information when
5024 receiving JOIN notify from server for client that we know but
5025 have incomplete information.
5027 * Rewrote parts of silc_server_remove_from_channels and
5028 silc_server_remove_from_one_channel as they did not remove the
5029 channel in some circumstances even though they should've.
5031 * Encryption problem encountered in server:
5033 The LEAVE command used to send the Channel Key packet to the
5034 router immediately after generating it. However, the code
5035 had earlier sent Remove Channel user packet but not immediately,
5036 ie. it was put to queue. The order of packets in the router
5037 was that Channel Key packet was first and Remove Channel User
5038 packet was second, even though they were encrypted in the
5039 reverse order. For this reason, MAC check failed. Now, this
5040 is fixed by not sending the Channel Key packet immediately but
5041 putting it to queue. However, this is more fundamental problem:
5042 packets that are in queue should actually not be encrypted
5043 because packets that are sent immediately gets encrypted
5044 actually with wrong IV (and thus MAC check fails). So, packets
5045 that are in queue should be encrypted when they are sent to
5046 the wire and not when they put to the queue.
5048 However, the problem is that the current system has not been
5049 designed to work that way. Instead, the packet is encrypted
5050 as soon as possible and left to the queue. The queue is then
5051 just purged into wire. There won't be any fixes for this
5052 any time soon. So, the current semantic for packet sending
5055 o If you send packet to remote host and do not force the send
5056 (the packet will be in queue) then all subsequent packets to the
5057 same remote host must also be put to the queue. Only after the
5058 queue has been purged is it safe again to force the packet
5061 o If you send all packets immediately then it safe to send
5062 any of subsequent packets through the queue, however, after
5063 the first packet is put to queue then any subsequent packets
5064 must also be put to the queue.
5066 Follow these rules and everything works fine.
5068 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Added new function silc_server_remove_clients_by_server to
5071 remove all client entries from ID list when the server connection
5072 is lost. In this case it is also important to invalidate all
5073 client entires as they hold the invalid server entry. This
5074 fixes fatal bug when server has lost connection and will reconnect
5077 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Made some sanity checks to silc_server_daemonise like to check
5080 whether the requested user and group actually exists.
5082 * Added sanity check to SKE's silc_ske_responder_finish to check
5083 that the public and private key actually is valid.
5085 * Invalidate the client's nickname when receiving Replace ID
5086 packet and the Client ID is being replaced. This means that the
5087 server will query the nickname if someone needs it (client)
5090 * Sort the ID Cache in client library when the ID Cache data
5091 has changed (needs sorting).
5093 * Do not allow for SILC client to create several connections to
5094 several servers. The client does not support windows right now
5095 and generating multiple connections causes weird behaviour.
5097 Irssi-silc client does support windows and can handle several
5098 connections without problems, see: www.irssi.org and SILC plugin.
5100 * Fixed some places where client was added to the IDList. The
5101 rule of thumb is following (in order to get everything right):
5102 If the client is directly connected local client then the
5103 `connection' argument must be set and `router' argument must be
5104 NULL to silc_idlist_add_client function. If the client is not
5105 directly connected client then the `router' argument must
5106 bet set and the `connection' argument must be NULL to the
5107 silc_idlist_add_client function.
5109 * The funtion silc_server_packet_send_local_channel actually did
5110 not check whether the client was locally connected or not. It
5111 does that now. Fixed a bug related to LEAVE command.
5113 * Fixed Remove Channel User payload parsing bug in server's
5114 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5116 * The server's silc_server_save_channel_key now checks also the
5117 global ID list for the channel as it might not be in the local
5118 list. Fixed a bug related to LEAVE command.
5120 * Is this the end of the [<unknown>] buglet that has been lurking
5121 around for a long time? A little for loop fix in server's
5122 silc_server_command_whois_parse that is used by both IDENTIFY
5123 and WHOIS command. At least, this was a clear bug and a cause
5124 of one type of [<unknown>] buglet.
5126 * WHOIS and IDENTIFY commands call the function
5127 silc_server_command_[whois/identify]_check function even if
5128 we are not router server.
5130 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Added --with-gmp configuration option. If set the GMP
5133 is always compiled in the SILC source tree. If not set then
5134 it is checked whether the system has the GMP3 installed. If
5135 it has then the GMP won't be compiled (the system's headers
5136 and library is used), if it doesn't have it then the GMP is
5137 compiled in the SILC source tree.
5139 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Changed RSA private exponent generation to what PKCS #1
5142 suggests. We try to find the smallest possible d by doing
5143 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5144 not security fix but optimization.
5146 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Added new config entry [Identity] to fork the server and run
5149 it as specific user and group. A patch from Bostik.
5151 * Imported Dotconf configuration library into lib/dotconf.
5152 This will be used to create the SILC configuration files later.
5153 It will appear in the distsribution after this commit.
5155 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * A big code auditing weekend happening. Auditing code for
5158 obvious mistakes, bugs and errors. Also, removing any code
5161 Removed files for being obsolete:
5163 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5164 inline in the file lib/silcutil/silcbuffer.h)
5166 o lib/silcutil/silcbufutil.c (the header has inline versions)
5168 Changed code to fix possible error conditions:
5170 o The buffer formatting routines now check that the destination
5171 buffer really has enough space to add the data. This applies for
5172 both buffer formatting and unformatting
5173 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5174 unformatting was changed to accomodate following rules:
5175 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5176 sent to the function while XXX_*STRING will not allocate or copy
5177 the data into the buffer. Instead it sets the pointer from the
5178 buffer into the pointer sent as argument (XXX_*STRING used to
5179 require that the pointer must be allocated already). This change
5180 makes this whole thing a bit more consistent and more optimized
5181 (note that the data returned in the unformatting with XXX_*STRING
5182 must not be freed now). The routines return now -1 on error.
5184 o Tried to find all code that use buffer_format and buffer_unformat
5185 and added return value checking to prevent formatting and
5186 especially unformatting errors and possible subsequent fatal
5189 o Changed ske->x and ske->KEY to mallocated pointers in
5190 lib/silcske/silcske.h. Fixed possible data and memory leak.
5192 o Added return value checking to all *_parse* functions. Fixed
5193 many memory leaks as well.
5195 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5196 so that buffer overflows would not happen. All code now also
5197 checks the return value as it can fail.
5199 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Added reconnection support to server if the normal server looses
5202 its connection to the router (for example if router is rebooted).
5203 The server performs normal reconnection strategy implemented
5204 to the server. Affected file silcd/server.c.
5206 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Added new packet type SILC_PACKET_SET_MODE that is used to
5209 distribute the information about changed modes (for clients,
5210 channels and clients channel modes) to all routers in the
5211 network. Updated the protocol specification accordingly.
5213 Added functions into silcd/packet_send.c and
5214 silcd/packet_receive.c: silc_server_send_set_mode,
5215 silc_server_set_mode.
5217 Added new files silcmode.[ch] into lib/silccore that implements
5218 the encoding and decoding of Set Mode Payload. Added new type
5219 SilcSetModePayload. Moved the definitions of different modes
5220 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5222 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Oops, a little mistake in server's connection authentication
5225 protocol. The protocol is not ended with FAILURE but with
5226 SUCCESS if the authentication is Ok. :) Affected file is
5229 * Implemented NICK_CHANGE notify handling in server in the file
5230 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5231 the local clients on the channel. After the changing nickname
5232 in router environment snhould work and the [<unknown>] nickname
5233 should appear no more.
5235 The silc_server_replace_id function that receives the Replace ID
5236 payload now sends the NICK_CHANGE notify type also in the file
5237 silcd/packet_receive.c
5239 * Changed WHOIS and IDENTIFY command to support the maximum amount
5240 of arguments defined in protocol specs (3328 arguments). This
5241 fixed a bug that caused problems when there were more than three
5244 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Added extra parameter, command identifier, to the
5247 silc_client_send_command so that explicit command identifier
5250 Changed that ID list routines uses specific command identifier
5251 when sending WHOIS/IDENTIFY requests to the server so that they
5252 can be identified when the reply comes back.
5254 Affected files lib/silcclient/command.[ch],
5255 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5257 * Added `sender' argument to silc_server_packet_send_to_channel
5258 to indicaet the sender who originally sent the packet to us
5259 that we are now re-sending. Ignored if NULL. Affected file
5260 silcd/packet_send.[ch].
5262 * Added some server statistics support in silcd/server_internal.h
5263 SilcServerStatistics structure and around the server code. Also
5264 send some nice statistics information when client is connecting
5267 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Fixed channel ID decoding in server's JOIN command reply in
5270 silcd/command_reply.c
5272 * Fixed braodcasting of replace ID payload to not to send it if
5273 we are standalone server in silcd/packet_receive.c.
5275 * Fixed all channel message sending routines to not to send
5276 packets to clients that has router set, since they are routed
5277 separately in the same function earlier. Affects file
5278 silcd/packet_send.c and all channel packet sending functions.
5280 * In USERS reply, res_argv[i] are not allocated, the table
5281 is allocated. Thus changed that free the table, not its
5284 * In server's whois_check and identify_check if the client is
5285 locally connected do not send any WHOIS commands - they are not
5288 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Fixed some minor bugs in client when sending WHOIS command. The
5291 arguments was in wrong order.
5293 * Removed statis function add_to_channel from server in
5294 silcd/command.c that was previously used with the joining but
5297 * Tested USERS command in router environment successfully with two
5298 routers, two servers and two clients.
5300 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Reorganized the USERS command and command reply in client library
5303 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5304 When the command is given by user we register a pending command
5305 callback that will reprocess the command after the reply has been
5306 received from the server. When reprocessing the packet we then
5307 display the information. Thus, the USERS information is displayed
5308 now in the command callback instead of in the command reply
5309 callback. The processing of the command is same as previously
5310 when server has sent the command reply in the JOINing process.
5312 * Added to USERS command in silcd/command_reply.c to join the client,
5313 we didn't use to know about, to the channel after we've created
5314 a client entry for it. Also, for clienet we did know already still
5315 check whether it is on the channel or not and add it if not.
5317 * Removed silc_server_command_join_notify as the function and its
5320 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Changed the client's pending command handling to the same as the
5323 server's pending command handling. It is also now possible to
5324 execute command reply functions from other command reply
5325 function as the function callbacks for commands and command
5326 replies are one and same. The pending commands are not static
5327 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5328 in client connection context. Thus, pending commands are server
5329 connection specific as it is convenient.
5331 Changed the function silc_client_command_pending and
5332 silc_client_command_pending_del and added new function
5333 silc_client_command_pending_check. Removed the
5334 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5337 * Added cmd_ident, current command identifier, to the client
5338 connection context in lib/silcclient/client.h to keep track on
5339 command identifiers used in command sending. Client's command reply
5340 function handling now supports the mandatory command identifiers.
5342 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5343 funtions in client to fully support pending command callbacks.
5345 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5346 as one of the arguments to the application in the command reply
5349 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5350 before first releasing SILC but came back. Now it is removed again
5351 and should come back nomore. The FORWARDED flag was used only
5352 by the JOINing procedure by forwarding the command packet to router.
5353 Now, the JOINing procedure has been changed to more generic (due
5354 to various router environment issues) and FORWARDED is not needed
5355 anymore for anything. The protocol specification is yet to be
5358 Now, removed silc_server_packet_forward from server and the flag
5359 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5361 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Renamed NAMES command to USERS command. The NAMES was named that
5364 due to historical reasons. Now it is renamed. Also, rewrote
5365 parts of the USERS command. The nickname list is not sent anymore
5366 by the server. Only Client ID and mode lists are sent in the USERS
5367 command. Changed this also to the protocol specification.
5369 The client now resolves the names and stuff after it receives
5370 the USERS list from the server when joining to the channel.
5372 * WHOIS and IDENTIFY commands has been changed to support multiple
5373 Client ID's per command. One can now search for multiple users
5374 in the network by sending only one WHOIS or IDENTIFY command.
5375 Changed the code and the protocol specifications.
5377 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5378 uses silc_server_command_whois_parse to parse the request. */
5380 * If normal server, do not parse the WHOIS and IDENTIFY requests
5381 before sending it to the router. Saves some time.
5383 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Fixed JOIN command on client library. Wrong number of arguments
5386 used to crash the client.
5388 * Added silc_server_channel_has_global function to check whether
5389 channel has global users or not.
5391 * Added silc_server_channel_has_local function to check whether channel
5392 has locally connected clients on the channel.
5394 * The silc_server_remove_from_one_channel now checks whether the
5395 channel has global users or not after given client was removed from
5396 the channel. It also checks whether the channel has local clients
5397 on the channel anymore. If it does not have then the channel entry
5398 is removed as it is not needed anymore.
5400 * The silc_server_notify now checks on JOIN notify whether the joining
5401 client is one of locally connected or global. If it is global then
5402 the channel has now global users on the channel and that is marked
5403 to the channel entry. Also, it now saves the global client to
5404 global list who is joining and JOINs it to the channel. This is
5405 for normal server, that is.
5407 Changed silc_server_send_notify_on_channel,
5408 silc_server_packet_relay_to_channel and
5409 silc_server_packet_send_to_channel check if we are normal server
5410 and client has router set (ie. global client) do not send the
5411 message to that client, as it is already routed to our router.
5413 * Implemented LEAVE notify type handling in silc_server_notify
5416 * Tested LEAVE command in router environment successfully. Tested
5417 with two routers, two servers and two clients.
5421 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5423 * Implemented SIGNOFF notify type handling in silc_server_notify
5426 * silc_server_remove_id now removes the client entry from all channels
5427 it has joined and thusly sends SIGNOFF notify type.
5429 * Rewrote the NAMES list generation in server by removing two excess
5430 loops. The lists are created now inside one loop.
5432 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * silc_server_remove_channel_user checks now also global list
5435 for channel and client.
5437 * silc_server_new_channel_user checks now both local and global
5438 list for channel and client. Fixed a bug in client id decoding.
5439 Used to decode wrong buffer.
5441 * silc_server_channel_message checks now both local and global
5442 list for channel entry.
5444 * Tested channel joining (hence JOIN) in router environment
5445 successfully. Tested with two routers, two servers and two
5448 * Tested channel message sending in router environment successfully.
5450 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added silc_server_save_channel_key into server.[ch] to save the
5453 received channel key in Channel Key payload processing. It is
5454 also used in JOIN command reply handling.
5456 Equivalent function silc_client_save_channel_key added into
5457 client.[ch] into client library.
5459 * Changed JOIN command reply to send information whether the channel
5460 was created or not (is existing already) and the channel key
5461 payload. Changed protocol specs accordingly.
5463 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5464 the request was sent by ID and not by nickname. Crashed on
5467 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5470 now correctly save the received data.
5472 * silc_server_free_sock_user_data now notifies routers in the
5473 network about entities leaving the network.
5475 At the same time implemented functions silc_server_remove_id
5476 and silc_server_send_remove_id to receive and send REMOVE_ID
5477 packets. The packet is used to notify routers in the network
5478 about leaving entities. The ID removed will become invalid in
5481 * Added function silc_idlist_del_server into server. Removes and
5482 free's server entry from ID list.
5484 * silc_server_private_message function now checks, if we are router,
5485 that the destination ID really is valid ID, naturally.
5487 * In router when NEW_ID packet is received (for new client) the
5488 hash of the Client ID is saved in the ID Cache but the
5489 client->nickname is set to NULL, instead of putting the hash
5492 IDENTIFY command now also checks that client->nickname must be
5493 valid. If it is not if will request the data from the server who
5494 owns the client. Added new function
5495 silc_server_command_identify_check.
5497 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5498 to set the command to already allocated Command Payload.
5500 * Tested private message sending in router environment with two
5501 routers, two servers and two clients. Fixed minor bugs and now
5504 * Fixed segfault from client's NAMES command. Used to crash if
5507 * Forwarded packets must not be routed even if it is not destined
5508 to the receiver. Changed server code comply with this.
5510 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Added `require_reverse_mapping' boolean value to ServerParams
5513 structure. If TRUE (not default) the server will require that
5514 the connecting host has fully qualified domain name.
5516 If the reverse mapping is not required and hostname could not be
5517 found the IP address is used as hostname.
5519 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Implemented version string checking to both client and server.
5522 The check is incomplete currently due to the abnormal version
5523 strings used in development version of SILC.
5525 * Changed all command functions in server to use the new
5528 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Changed char *data to unsigned char *data in ID Cache system to
5531 support binary data as ID Cache data. Changed code to support
5532 binary data in lib/silccore/idcache.c.
5534 * Renamed silc_server_packet_relay_command_reply to
5535 silc_server_command_reply as it is normal packet receiving
5536 function. Rewrote the function to accept command replys for
5537 servers and not only for clients.
5539 * Mark remote router always as registered server if we are connecting
5540 to it. Otherwise, commands sent by the router to us are ignored.
5542 * All ID List find routines now returns the ID Cache Entry pointer
5543 as well if requested.
5545 * WHOIS command works now in router environment, tested with two
5546 routers, two servers and two clients.
5548 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5549 in router environment (as it is almost equivalent to WHOIS) but
5550 hasn't been tested thoroughly. Added new functions:
5552 silc_server_command_identify_parse
5553 silc_server_command_identify_send_reply
5554 silc_server_command_identify_from_client
5555 silc_server_command_identify_from_server
5557 * Disabled route cache adding because adding two different ID's with
5558 same IP replaces the old cache entry thus giving wrong route.
5559 The entry->router->connection is always the fastest route anyway
5560 so route cache may not be needed. Of course, new routes maybe
5561 established after receiving the ID when the entry->router->connection
5562 might not be anymore the most optimal.
5564 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Add route cache for received ID for fast routing.
5568 * Added silc_server_packet_route to route received packet on router
5569 that is not destined to us.
5571 * Renamed silc_server_get_route to silc_server_route_get.
5573 * Added id_string and id_string_len fields into SilcServer to
5574 include encoded ServerID for fast comparing without excess
5575 encoding of the ID's.
5577 * Cleaned up WHOIS command on server side. Added following static
5580 silc_server_command_whois_parse
5581 silc_server_command_whois_check
5582 silc_server_command_whois_send_reply
5583 silc_server_command_whois_from_client
5584 silc_server_command_whois_from_server
5586 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5587 arguments in command replies. All command functions should be
5588 updated to use this macro.
5590 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Minor typo fixes on command reply handling on server.
5594 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Added silc_server_command_add_to_channel internal routine to add
5597 the client to the channel after router has created the channel and
5598 sent command reply to the server.
5600 * Added generic silc_server_send_command to send any command from
5603 * Use static buffer with ID rendering instead of duplicating data.
5605 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Fixed a channel user mode bug when joining to a channel server gave
5608 everybody channel founder rights, oops.
5610 * We mark ourselves as the router of the incoming server connection
5611 if we are router ourselves. This way we can check in some packet
5612 sending functions whether it is locally connected server. For
5613 incoming router connections we put NULL.
5615 * For router sending packets locally means now always sending the
5616 packet cell wide; to local clients and local servers. For normal
5617 server sending packet locally means sending it to only local
5620 * Fixed the JOIN command to really work in router environment. If the
5621 channel is created it is always created by the router. Router is
5622 also responsible of making the initial joining to the channel,
5623 sending JOIN notify to the sending server and distributing
5624 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5625 does not exist server doesn't do anything else but forward the
5626 command to the router which performs everything.
5628 * Added silc_server_send_channel_key function to send the Channel Key
5631 * Added silc_server_create_channel_key to create new channel key. The
5632 channel key is now re-generated everytime someone joins or leaves
5633 a channel, as protocol dictates. Note: channel->key_len is the
5636 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5639 packet_receive.[ch] to separate packet sending and receiving
5640 routines. The server.[ch] now includes everything else including
5641 actual packet processing (writing and reading data) and other
5644 Renamed silc_server_private_message_send_internal to
5645 silc_server_send_private_message. The routine is still though
5646 used only to relay private messages as server does not send
5647 private messages itself.
5649 Renamed silc_server_new_channel to silc_server_create_new_channel
5650 and added new function sicl_server_new_channel that handles the
5651 incoming New Channel packet. Added also new sending function
5652 silc_server_send_new_channel to send New Channel Payload.
5654 * Added new function silc_server_notify to process incoming notify
5655 packet to the server/router. Server may then relay the notify
5656 to clients if needed.
5658 * Added new function silc_server_new_channel_user to process incoming
5659 New Channel User packet. Router will redistribute the packet and
5660 send JOIN notify to its local clients and locally connected servers
5661 if needed. Normal server will send JOIN notify to its local client
5662 on same channel when received this packet. Added also corresponding
5663 sending function silc_server_send_new_channel_user to sent the
5666 * Added boolean route argument to send_notif_to_channel and
5667 packet_send_to_channel functions to attempt to route the packet
5668 if it is TRUE and send only locally if it is FALSE.
5670 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * silc_server_replace_id now broadcasts the received replace ID
5673 packet if it is not broadcast packet already. The router must
5674 broadcast to inform other routers about changed ID.
5676 * Added backpointer to server's router into SilcServer context in
5677 silcd/server_internal.h.
5679 * Fixed silc_server_packet_broadcast to send correct broadcast
5682 * The channel key is now distributed to the local client as soon
5683 as it is received from the router (in router environment) so that
5684 no other packet may be sent for the channel until client has
5687 * silc_server_remove_channel_user now broadcasts the received
5688 Remove Channel User packet if it is not broadcast packet already.
5689 The router must broadcast to inform other routers about removed
5692 * Added users field into SilcPacketContext that is a reference count
5693 of the context. One can increase the reference count by calling
5694 silc_packet_context_dup which is now changed to just increase the
5695 reference count instead of duplicating the data. The reference
5696 count is decresed by calling silc_packet_context_free that will
5697 free the data after the reference count hits zero.
5699 For now on the packet context and everything allocated into it
5700 (including the raw packet from network) must be freed by calling
5701 the new silc_packet_context_free function. Added also new function
5702 silc_packet_context_alloc that must be used now to allocate the
5703 context. This also means that if a routine is asynchronous from
5704 silc_[client/server]_packet_parse_type the packet context must
5705 be duplicated by calling silc_packet_context_dup. Otherwise it
5706 gets free'd after silc_[client/server]_packet_parse_type returns.
5707 Also, one must remember that if packet is duplicated then its
5708 reference count must be decresed by calling the free function as
5709 many times as it was duplicated.
5711 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5712 from both client and server.
5714 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Made joining to a channel working in router environment.
5718 * Cleaned up JOIN command on server side and create function
5719 silc_server_command_join_channel internal routine to make the
5722 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5724 * Changed silc_command_pending list to SilcDList. Also, added
5725 `ident' field to SilcServerCommandPending structure to identify
5726 the reply and to call correct callback.
5728 Added silc_server_command_pending_check function to replace the
5729 corresnponding macro. The silc_command_pending list is not
5732 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5733 to set identifier to previously allocated Command Payload. It
5734 is used to set identifier for command when resending Command
5737 * Added silc_command_payload_encode_payload to encode Command
5738 Payload buffer from SilcCommandPayload structure.
5740 * Added silc_argument_payload_encode_payload to encode Argument
5741 payload buffer from SilcArgumentPayload structure.
5743 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Changed WHOIS command to support router connection on server side.
5746 The whois request is always sent to router unless the server is
5747 standalone server. After server has received the reply from the
5748 router will it send the reply to the client.
5750 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5751 broadcast received broadcast packet. The function is used only
5752 by router. The broadcast packet is always sent to the router's
5755 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5756 render given ID to printable string, for log files for example.
5758 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Made basic router to router connections working. At least they
5761 can now connect to each other but nothing really works the way
5762 they are supposed - yet.
5764 * Added new initiator token to RouterConnection configuration
5765 file in silcd/serverconfig.[ch]. It is used to tell whether we
5766 are the initiator to the remote router or whether we'll expect
5767 the other end to connect.
5769 * Moved registering of listener task to silc_server_init, hence
5770 the server starts listenning as soon as it is run, even if it
5771 does not have connections to other routers. Let's see how well
5774 * Changed default connection retry timeouts for more suitable in
5777 * Removed cipher and such arguments from silc_idlist_add_client
5778 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5779 Added new function silc_idlist_add_data to add the keys and stuff
5782 * Added SilcIDListData structure and added it to SilcClientEntry
5783 and SilcServerEntry as their first field in the structure. This
5784 way we can explicitly cast the ID entries to the SilcIDListData
5785 structure and get common data for the entries. In past, we had
5786 to first check what type of connection it is and then cast it to
5787 correct ID entry type. Now, we can directly cast the opaque
5788 pointer to the SilcIDListData (no matter what ID entry it actually
5789 is) and get the data needed.
5791 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5794 in some circumstances even if threre were timeout tasks, though not
5795 IO tasks, but tasks anyway. Now fixed.
5797 * Defined SilcServerConnection structure to hold connection specific
5798 stuff about directly connected servers and routers. The definition
5799 is currently in silcd/server_internal.h. I thought about having
5800 a bit more important role fro this struct but for now it is used
5801 only when connecting to other server (or router actually).
5803 * Added connecting retry support in server when connecting to
5804 router(s). The retry feature implement exponential backoff
5805 algorithm. Also, added SilcServerParams structure to hold default
5806 parameters for server. For now, it include these retry settings
5807 and are hard coded. After server is moded to be as Silc Server
5808 Library this structure will be more important.
5810 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Changed client librarys channel->clients table to SilcList and
5813 changed code accordingly.
5815 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Changed client's channel table to SilcList and changed code
5818 accordingly. Also changed SilcChannelClientEntry to include back-
5819 pointer to the channel so that client entry can use that structure
5820 as list as well and we have fast cross-reference to the channel.
5821 This change dramatically decreased the complexity of channel
5822 handling with client entry and vice versa (removed one extra
5823 loop when searching for channel entry from many functions).
5825 * Changed server->sim from table to SilcDList and changed code
5828 * NAMES command can now be used from user interface. It will show
5829 the user list on the channel, neatly.
5831 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5832 Code now saves realname of the user if it becomes available.
5834 * Renamed configure.in to configure.in.pre and made ./prepare
5835 script to automatically add correct version string to
5836 configure.in which it creates from configure.in.pre.
5838 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * NAMES command reply now shows users mode with the nickname when
5843 * Moved silc_client_ch[u]mode[_char] functions from
5844 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5845 place sucks, they are utility functions and should be in some
5848 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5850 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5853 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Added TRQ (efficient deque and list library) into lib/trq. This is
5858 a very good list library that is currently used in the SILC. Defined
5859 SilcList API over the library because I didn't like the API very
5860 much. See lib/trq/silclist.h for the API and examples of how to
5861 use the API. Fixed various places in the code to use the new
5862 SilcList API. The SilcList is meant for lists that has a structure
5863 already defined as a list. It is not suitable to add just some
5864 context to the list (in TRQ, the context is the list actually).
5866 So, I defined SilcDList that can be used for the purpose where
5867 predefined list structure does not exit. This can be used as
5868 such list. Now some context just can be added to the SilcDList.
5869 Currently this list is not used in the SILC just yet, though there
5870 are a lot places where this can replace dynamically allocated
5871 tables and I will fix these places, later, to use SilcDList.
5872 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5873 and use TRQ internally).
5875 Also fixed some annoying warning messages that the original TRQ
5876 code generated. Also minor changes to TRQ's Makefile.in.
5878 * Added support for querying by Client ID to both WHOIS and
5879 IDENTIFY commands into server, as required by the protocol.
5881 * Removed method function pointers from SilcBuffer structure. They
5882 weren't used to anything and just increased the context size for
5883 no good reason. This change also made silc_buffer_alloc and
5884 silc_buffer_free functions inline functions.
5886 * Disabled command flooding detection support until it's fixed so
5887 that it accepts commands in but does not execute them more than once
5890 * Added silc_net_localhost(), to return local hostname, into
5891 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5892 that must be initialized before calling silc_client_init.
5894 * Added new function: silc_server_send_notify_on_channels to send
5895 notify messages to all channels client has joined. It is assured
5896 that the message is sent only once per client.
5898 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5899 lib/silcutil/silcutil.[ch] as silc_format function. The new
5900 function is generic and is used by server as well, not only by
5901 the logging routines.
5903 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5904 the provided version string was not acceptable. Added new function:
5905 silc_ske_check_version into lib/silcske/silcske.h. The function
5906 must be implemented by the application (client or server) and it
5907 does not reside in the SKE library. The function checks the version
5908 string remote end sent.
5910 * Added back pointers (to opaque context and to SilcSocketConnection)
5911 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5913 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5914 duplicate packet context structure.
5916 * Changed `notify' client operation to send same arguments as client
5917 receives from server except for ID's. ID's are mapped to correct
5918 ID entry and that is returned. Also, if channel entry is not sent
5919 by server but the notify is for channel the channel entry is sent
5920 to application (otherwise application doesn't know that it is for
5921 channel (library gets it from packet's Destination ID)).
5923 * Added silc_client_remove_from_channels into client library to
5924 remove a client from all channels it has joined to. Used when
5925 received SIGNOFF notify from server. Added also new function
5926 silc_client_replace_from_channels to replace old ID entry with
5927 new ID entry on all channels. Used when received NICK_CHANGE
5930 * Fixed ID Cache list handling in silc_idlist_get_client in
5931 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5932 to get (or query) client by ID.
5934 * Updated TODO list.
5936 * Added connection authentication status message defined by the
5937 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5938 support for these into the code in client and server side.
5940 * Added generic function silc_client_send_command to send any command
5941 with variable argument list. Application should use this function
5942 to send commands if the command functions provided by the library
5943 does not suite for the application's user interface needs.
5945 * Added new `failure' client operation. Application is notified about
5946 received failure packet if client is executing a protocol. In this
5947 case the protocol's execution has failed.
5949 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5950 is required by the protocol.
5952 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5953 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5956 * Added status flag to SilcSKE object to indicate realtime status
5957 of the SKE protocol.
5959 * Application receives now exactly same command reply arguments as
5960 the library receives from server. However, if ID is received the
5961 corresponding ID entry is returned to the application (eg. Client
5962 ID is mapped to correct SilcClientEntry entry and that is returned).
5963 Changed command_reply client operation due to this change.
5965 * Changed all ID's in commands and in command replys as ID Payloads.
5966 Change affected both client and server side codes.
5968 All ID's sent in SILC network (with execption of ID's in SILC
5969 Packet header) are sent in ID Payload to support variable length
5972 * Server now notifies nick changes and notifies all clients on
5973 the channels about the new nickname (about the new Client ID,
5976 * Implemented CMODE command to change channel modes. Supports all
5977 channel modes defined by the protocol specs except ban and invite
5978 lists. (Also, private channel key mode is supported but support for
5979 setting private channel key in client is missing, thus, this mode
5980 has no effect on client side (except that server requires that the
5981 client uses private channel key and normal channel traffic does not
5984 Also, invite mode works per se, but INVITE command does not work
5985 yet correctly, so you can set channel as invite only channel but
5986 inviting clients to the channel does not work (it is yet to be
5987 thought what's the best way to do it).
5989 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5990 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5991 Implemented CUMODE command to change user's mode on the channel.
5992 Supports all modes defined by the protocol specs.
5994 * Added NAMES command reply to return users modes on the channel.
5996 * Removed unnecessary and slow ciphers from lib/silccrypt.
5998 * Set SO_KEEPALIVE option to connection sockets by default.
6000 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6002 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6003 redefined the Notify Payload into protocol specs.
6005 * Added silc_id_payload_parse_id to get ID directly from raw
6008 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6011 accept searching by Client ID as well.
6013 * Added support for LEAVE and SIGNOFF notify types in client library.
6015 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6016 to parse ID Payload from raw data.
6018 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Added flags parameter into silc_ske_assemble_security_properties
6021 function in lib/silcske/silcske.[ch].
6023 * Changed notify client operation to fit better for notify messages
6024 sent by server. The notify payload received from server is now
6025 passed to the application (after parsing it to SilcNotifyPayload).
6026 It is application's responsibility to retrieve the arguments
6027 from the payload and show the message the way it wants. The message
6028 sent by server is implementation specific.
6030 * Changed public keys to comply with the protocol specification.
6031 Old public keys are not supported anymore and are not compatible.
6033 * Removed nickname from Channel Payload as the latest draft removed
6034 it. The client must resolve the nickname from the NAMES command
6035 reply received when it joined the channel.
6037 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6039 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Fixed some errors in protocol specification drafts.
6043 * Created lib/silccore/silcnotify.c to implement Notify Payload
6044 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6045 generic payloads described by protocol specifications. The file
6046 includes implementations for ID Payload and Argument Payload.
6048 * Changed Command Payload implementation to use the new Argument
6049 Payload. Changed command_xxxx_payload to command_payload_xxxx
6050 to comply with SILC coding conventions.
6052 * Added suppport for Argument Payload handling in Notify Payload
6053 implementation as protocol requires it. Added the new support
6054 into server and client lib as well.
6056 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added support for multiple nicknames on same channel. [n] is
6059 added locally to the nickname if there are more than one same
6060 nicknames on the channel.
6062 * Server now sends all nicknames that matched WHOIS request.
6063 Client also shows the list received from server.
6065 * Added TOPIC command to client side. User can now set and show
6066 current topic on channel.
6068 * Added MOTD command to client and server. Also, server sends the
6069 motd when client connects to the server.
6071 * Changed version strings to comply ISO 8601.
6073 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Fixed protocol error handling in client library. It should now
6076 cope even if the SKE fails for some reason.
6078 * Made new protocol specification drafts for submitting to IETF.
6080 * Implemented TOPIC command to server in silcd/command.c.
6082 * Added two new notify types into lib/silccore/silcnotify.h:
6083 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6084 notify nickname change and topic setting/change on a channel.
6086 * API change of command_reply operation in client library. The
6087 application gets now the status type received from server as well.
6089 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6093 * Cras fixed and optimized the packet handling even further and
6094 it should work now. Minor change to the prototype of function
6095 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6097 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * Added new function into lib/silcutil/silcschedule.[ch]:
6100 silc_schedule_with_fd to select() a specified fd. The function
6101 returns after timeout expires or data arrives or goes. The
6102 function is used by packet routines to wait that all data is
6103 received from network.
6105 * Fixed data reading from network in lib/silccore/silcpacket.c.
6106 The code now assures that all data is read from the fd and then
6107 continues packet processing. This was a bug fix since the code
6108 used to drop some data in some circumstances.
6110 * Added new function into lib/silcclient/client.[ch]:
6111 silc_client_start_key_exchange to start key exchange after
6112 connection has been established to server. The code internally
6113 now uses this funtion but its main purpose was to provide it
6114 for applications that perform their own connecting. After
6115 application has created a connection it merely calls this
6116 function to start the key exchange between client and server.
6117 The library takes care of everything else after that.
6119 Updated also lib/silcclient/README to explain the usage of
6122 * Do not send to application information that connection has
6123 been established. Application gets notified it by connect
6126 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Applied cras's patch to add silc_schedule_one function. The
6129 function runs scheduler once and returns.
6131 * Fixed the scheduler after cras messed it up. The timeout
6132 handling works now as it's supposed to work.
6134 * Added into lib/silccore/ silcnotify.h to include notify
6135 message types support. Changed silc_server_send_notify*
6136 functions, in server.[ch], to support those new notify types.
6137 Added the support for the notify types into client library,
6138 as well. Added new notify client operation into ops.h in
6141 * Changed silc_server_packet_send_to_channel to send normal
6142 packets instead of just channel message packets. The function
6143 is now used to send the notify packets to channels. It is not
6144 used to send channel message packets anymore, as server never
6147 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6148 va_arg()s as it seems to require it nowadays. I guess, if SILC
6149 is compiled with older va_arg() the new code should work anyway.
6151 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Splitted core library. Core library (lib/silccore) includes
6154 now only SILC protocol specific core (and common) components.
6155 Created new utility library (lib/silcutil) that includes more
6156 generic purpose stuff. The stuff for util library was taken
6157 from the old core library. This was minor and easy split.
6159 * Created SILC Client Library (lib/silcclient) that includes
6160 implementation of the SILC client without user interface. This
6161 was major move from silc/ directory. The code has been changed
6162 so that it is transparent towards the user interface. The
6163 silc/ directory includes now the same user interface as before
6164 and it uses the new client library. Read lib/silcclient/README.
6165 Basicly, the client library performs everything else related
6166 to SILC except user interface handling. Also, configuration
6167 files are considered to be part of user interface and library
6168 does not handle them.
6170 This change also changed a lot of structures, function naming etc.
6171 Most important change was that SilcClientWindow object was
6172 renamed to SilcClientConnection in the client library. Created
6173 also new file lib/silcclient/ops.h. Also added new files
6174 silc/local_command.[ch] and silc/client_ops.[ch].
6176 All these changes were made to make it easier for user interface
6177 designers to create what ever user interface for the SILC client
6180 It is also expected that the server will be moved to lib
6181 directory as well and SILC Server Library will be created;
6182 sometimes in the future.
6184 * Removed Local commands from lib/silccore/silccommand.h as
6185 they are application specific and new client library does not
6186 handle any of those anymore.
6188 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6189 old client implementation in silc/.
6191 * Added support for callback functions in SILC_LOG_* macros.
6192 Application can now set its own callbacks that will be called
6193 instead of using the default functions that will always print
6194 the debug messages to stderr (or stdout). Also, debugging can
6195 now be disabled by setting silc_debug to FALSE and re-enabled by
6196 setting it to TRUE. Note, that logging will still work even
6197 if debugging is disabled.
6199 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6200 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6201 silc_log_reset_debug_callbacks.
6203 * To enable debugging in silc client one must give now -d
6204 option on command line.
6206 * Changed silc_schedule_init to automatically allocate task queues
6207 if they are not allocated before calling it.
6209 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Added GMP 3.1 into math library.
6213 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6216 a channel in SILC network. The packet is used by servers and
6217 routers to notify other routers that user has left a channel.
6218 This little feature was missing until now. Added the feature
6219 to protocol specification as well.
6221 Added functions: silc_server_send_remove_channel_user and
6222 silc_server_remove_channel_user into server.[ch].
6224 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6225 lib/silccore/silcpacket.h. However, they are not implemented
6228 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Fixed joining to a channel and sending channel messages
6231 between server and router. The channel message sending should
6232 now work inside a cell.
6234 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Fixed the private message sending between server and router.
6237 The private message sending should now work inside a cell.
6239 * Added silc_server_replace_id into server.[ch] to replace
6240 existing ID in the SILC network.
6242 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6243 and silc_idlist_replace_server_id into idlist.[ch] in server.
6245 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Fixed the server to server connections. Server can again now
6248 connect to router. Router to router connections probably does
6251 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Added dynamic protocol registering support. Now protocols can
6254 registered and unregistered on the fly. Patch by cras.
6256 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Added lib/contrib directory to hold routines that some platforms
6259 don't have but are needed by SILC.
6261 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6262 into lin/contrib to provide getopt() and getopt_long() for
6263 those who don't have it.
6265 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Added AWAY command to client. When away message is set and
6268 client receives a private message packet the client automatically
6269 replies to the sender with the away message.
6271 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6272 bug seemed to be the cause of recent problems when compiling
6275 * Added version detection support to SKE protocol specification
6276 and added the new changes to the SKE implementation as well.
6277 There were other minor changes in the SKE protocol as well.
6279 Many changes in lib/silcske/silcske.[ch] and in
6280 lib/silcske/payload.[ch].
6282 * Added ^U functionality, clear input line. Patch from cras.
6284 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Mainly small bugfixes on core library. Fixed some debugging
6287 logging and buffer overflow in silclog.c.
6289 * Updated config.sub and config.guess on the distribution tree.
6291 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Added command lagging support in server. Client may execute
6294 commands now only once in two seconds.
6296 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Optimized packet reception. MAC computation and checking is now
6299 also more optimized. A lot previously duplicated code is now
6300 used as generic by both client and server.
6302 * Fixed key pair generation in clientutil.c
6304 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Added into lib/silccore/silcbufutil.[ch] new function;
6307 silc_buffer_realloc.
6309 * Moved generic packet sending/encryption functions to
6310 lib/silccore/silcpacket.[ch] from client and server. Some
6311 rewriting of the functions.
6313 * Moved all generic packet reception/decryption functions to
6314 lib/silccore/silcpacket.[ch] from client and server. The
6315 packet processing is now much cleaner in both client and server.
6316 These were major changes in both client and server.
6318 * Created many common functions in server to do packet sending.
6319 Previously code were duplicated a lot, this has been removed
6322 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Rewrote major parts of the ID cache system. Don't know
6325 whether it is better now or not but at least the API is more
6328 * Major rewrite on ID cache stuff on client because of the ID
6329 cache API changes. Added idlist.c to client.
6331 * Also major rewrite on ID cache stuff on server as well.
6332 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6333 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6334 in hand, instead they are all put into the ID cache system now.
6335 All server_idlist_* routines uses ID cache now instead of
6336 traversing its own lists (those lists does not exist anymore).
6337 SilcIDList though still exists. Also, SilcXXXEntry's are
6340 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Finally made the SKE implementation compliant to the protocol
6343 specification. All mp integers are now binary encoded as
6344 opposed being HEX encoded.
6346 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6349 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6350 functions: silc_[encode/decode]_pem. Also added function
6351 silc_encode_pem_file to PEM encode with newlines ('\n') for
6354 * SILC public keys are now encoded either PEM or binary. Same
6355 option is for private keys as well. By default private keys
6356 are binary encoded and public keys PEM encoded. Silly HEX
6357 encoding were removed.
6359 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6360 function to create fingerprints.
6362 * Fixed a bug in SHA1; does not change the original data anymore.
6364 * Partly implemented INFO command on client and server side.
6365 Fixed CLEAR command. Changes to SERVER command; show current
6366 server(s) when giving command without arguments. Added
6367 VERSION command to client.
6369 * Added check to server that unregistered connections cannot
6370 execute commands (unless it is specificly allowed).
6372 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Fixed screen refresh.
6376 * Fixed channel joining bug from client. On some circumstances
6377 client tried to join to a channel it had already joined.
6379 * Added public key verification process into client's protocol.c.
6380 The client now verifies the public key from user and saves
6381 it into ~./silc/serverkeys/ directory.
6383 Added into: clientutil.[ch]: silc_client_verify_server_key.
6385 * Changed SKE protocol's silc_ske_initiator_finish function
6386 to accept callback function that verifies the received public
6387 key. Removed old silc_ske_verify_public_key function.
6389 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6391 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6392 silc_pkcs_private_key[_data]_set.
6394 * Made the password and public authentication more cleaner in
6395 server's protocol.c.
6397 * Removed historic and obsolete protocol `channel_auth' from
6398 both client and server.
6400 * Removed wrong way of sending command status messages from
6401 server to client in server's command.c. The old way violated
6402 protocol specification.
6404 Changes to silccore/silccommand.[ch]: removed
6405 silc_command_encode_status_payload -> not needed anymore,
6406 changed silc_command_encode_payload_va to accept extra
6407 argument on variable argument list. The argument type must
6408 now be provided to the function. Also, added new function:
6409 silc_command_encode_reply_payload_va which is same as
6410 normal command_encode_payload_va except command status type
6411 is provided as extra argument.
6413 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6415 * Added ~./silc directory handling. The directory includes the
6416 public and private keys for the client.
6418 Added silc_client_check_silc_dir, silc_client_create_identifier
6419 and silc_client_load_keys.
6421 * Implemented SILC protocol compliant public key. Added public
6422 and private key saving to and loading from files.
6424 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6425 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6426 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6427 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6428 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6430 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6431 silc_pkcs_load_[public/private]_key.
6433 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Added silc_server_get_route (route.[ch]) to get connection
6436 data for the fastest route for given ID.
6438 * Implemented INVITE command on client and server. The command
6439 were re-defined in the SILC Protocol Specification and the
6440 implementation now complies with the specification.
6442 * Implemented PING command on client and server.
6444 * Implemented NAMES command on client and server. The server side
6445 supports currently only normal server not router server yet.
6446 Some changes to NAMES definition in SILC protocol specification.
6448 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Implemented LEAVE command on client and server.
6452 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6453 again. This change was made to the protocol as well. Server
6454 should not violate the protocol specification anymore.
6456 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6458 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6459 was tested. SOCKS4 was not but should work anyway.
