1 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Do not print "you are now server operator" or similar when
4 giving /away command. Affected files are
5 irssi/src/silc/core/client_ops.c, silc-servers.h.
7 * Made the silc_server_command_pending_error_check to send
8 the same command reply payload it received back to the
9 original sender of the command. This way all arguments
10 that was received by the server will be received by the
11 client too. Affected file silcd/command.c.
13 * Added the silc_idcache_add to return the created cache entry
14 to a pointer. Affected file lib/silccore/silcidcache.[ch].
16 * Add global clients to expire if they are not on any channel.
17 This is because normal server will never know if they signoff
18 if they are not on any channel. The cache expiry will take
19 case of these entries. This is done by normal servers only.
20 The affected files are silcd/command_reply.c,
21 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
23 * If server receives invalid ID notification for WHOIS or
24 IDENTIFY and the ID exists in the lists, it is removed.
25 Affected file silcd/command_reply.c.
27 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
28 in client then client entry that it matches is searched and
29 the nickname is printed on the screen for user. Affected
30 file irssi/src/silc/core/client_ops.c.
32 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
34 * Use cache entry expire time in the LIST command reply to
35 purge old entries from the cache after the LIST command
36 reply has been received. This way we don't have non-existent
37 entries in the cache for too long. Affected file is
38 silcd/command_reply.c.
40 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
42 * If we are normal server, and we've not resolved client info
43 in WHOIS or IDENTIFY from router, and it is global client,
44 we'll check whether it is on some channel. If it is not
45 then we cannot be sure about its validity and will resolve it
46 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
49 * Search channel by name (if possible) rather than by ID
50 in IDENTIFY command's command reply. Affected file is
51 silcd/command_reply.c.
53 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
55 * Distribute to the channel passphrase in CMODE_CHANGE notify.
56 Updated specs and implemented it. Affected file silcd/command.c,
57 silcd/packet_send.c and silcd/packet_receive.c.
59 * Implemented the <founder auth> payload handling in the JOIN
60 command. If provided all conditions for channel joining
61 except requirement to provide correct passphrase can be
62 overrided by the channel founder. Updated the protocol specs.
63 Affected file silcd/command.c.
65 Added support for founder auth in JOIN command in client
66 library. Fixed the parsing of the JOIN command now to support
67 all options as they should be. The affected file is
68 lib/silcclient/command.c.
70 * Optimized the WHOIS and IDENTIFY commands to send the request
71 to router only if it includes nicknames or other names. If
72 they include only IDs then check the local cache first before
73 routing. Affected file is silcd/command.c.
75 * Added channels topic announcements. Affected file is
76 silcd/packet_receive.c and silcd/server.c.
78 * Fixed the silc_server_send_notify_topic_set to really destine
79 the packet to channel. Affected file silcd/packet_send.c.
81 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
82 library. Affected file lib/silcclient/client_notify.c.
84 * Added UMODE announcements. Affected file silcd/server.c.
86 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
88 * Memory leak fixes in:
90 lib/silcutil/silcsockconn.c
94 lib/silccrypt/silcpkcs.c
95 lib/silccore/silccommand.c
96 lib/silccore/silcidcache.c
101 * ROBOdoc documented the lib/silcske/groups.h file and a
102 bit changed the interface for better.
104 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
106 * Update the client entry context in the ID cache after
107 nick change. Affected file lib/silcclient/command.c.
108 Fixes the CUMODE command when regaining founder privileges,
109 and a little WHOIS problem.
111 * Fixed silc_net_gethostbyname to correctly call the
112 inet_ntop. Affected file lib/silcutil/silcnet.c.
114 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
116 * Added IPv6 support checking to the configure.in.pre, added
117 also --enable-ipv6 option to override the check. Affected
118 file configure.in.pre.
120 * The silc_thread_create now calls the start function
121 directly if threads support is not compiled in. Removes
122 ugly #ifdef's from generic code. Affected files are
123 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
125 * Added silc_net_gethostby[name/addr]_async to asynchronously
126 resolve. Affected files are lib/silcutil/silcnet.[ch].
128 * Added support for rendering IPv6 based server, client and
129 channel IDs. Affected file lib/silcutil/silcutil.c.
131 * Added support for creating IPv6 based server IDs. Affected
132 file is silcd/serverid.c.
134 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
136 * Added silc_net_gethostby[addr/name] into the
137 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
138 routines. Added silc_net_is_ip[4/6]. Affected file is
139 lib/silcutil/unix/silcunixnet.c. All routines that take
140 address as argument now supports both IPv4 and IPv6 addresses.
142 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
144 * Fixed LIST command reply sending in server. Affected file
147 * Server now sends the kicker's client ID in the KICK notify
148 to the kicked client. Affected file silcd/command.c.
150 * The client library now parses the kickers client ID and
151 UI displays it. Affected files lib/silcclient/client_notify.c
152 and irssi/src/silc/core/silc-channels.c, module-formats.c.
154 * Made all payload parsing function prototypes consistent.
155 They all take now const unsigned char * and uint32 pair as
156 the payload data instead of SilcBuffer. Changes all around
157 the source tree. Other unsigned char* -> const unsigned char*
158 changes around the tree as well.
160 * Optimized SFTP client and server packet sending not to
161 allocate new buffer for each packet but to recycle the
162 first allocated buffer. Affected files are
163 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
165 * Optimized the SFTP client to use SilcList instead of
166 SilcDList for requests, because it is faster. Affected file
167 is lib/silcsftp/sftp_client.c.
169 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
170 into lib/silccore/silcid.[ch].
172 Renamed silcpayload.[ch] into silcargument.[ch].
174 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
176 * If client entry is deleted with active key agreement
177 session, abort the session.
179 The silc_client_abort_key_agreement now calls the completion
180 callback with new SILC_KEY_AGREEMENT_ABORTED status.
182 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
185 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
187 * Don't use __restrict in older GCC's. Affected file is
188 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
190 * silc_net_localhost now attempts to reverse lookup the
191 IP/hostname. Affected file lib/silcutil/silcnet.c.
193 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
194 command. It can be used to gain founder privileges at
195 the same time when joining the channel.
197 Defined that the SILC_NOTIFY_TYPE_KICKED send the
198 kicker's client ID as well. Updated protocol specs.
200 Defined that the server must send SILC_COMMAND_IDENTIFY
201 command reply with error status to client who sent
202 private message with invalid client ID.
204 Updated the protocol specification.
206 * Added silc_server_send_command_reply to send any
207 command reply. Affected file silcd/packet_send.[ch].
209 * Added silc_id_payload_encode_data to encode ID payload
210 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
212 * The server now send IDENTIFY command reply with error
213 status if client ID in private message is invalid. Affected
214 file silcd/packet_receive.c.
216 * Save the server key file with server's IP address in
217 the filename instead of hostname. The affected file is
218 irssi/src/silc/core/client_ops.c.
220 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
222 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
225 * Added libtool support for compiling shared objects in
226 lib/silcsim. Affected file configure.in.pre and
227 lib/silcsim/Makefile.am. Original patch by cras.
229 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
231 * Pid file configuration, and server's config file fixes
232 patch by toma. Updated CREDITS file.
234 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
236 * Fixed silc_client_channel_message to not try to decrypt
237 the message twice if it resolved the destination client
238 information. This could cause of dropping one channel
239 message. Affected file lib/silcclient/client_channel.c.
241 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Added silc_client_run_one into lib/silcclient/silcapi.h and
244 lib/silcclient/client.c. This function is used when the SILC
245 Client is run under some other scheduler, or event loop or
246 main loop. On GUI applications, for example this may be
247 desired to used to run the client under the GUI application's
248 main loop. Typically the GUI application would register an
249 idle task that calls this function multiple times in a second
250 to quickly process the SILC specific data.
252 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
254 * Fixed silc_server_drop() for dropping the supplementary
255 groups as well, this could cause a security hole on some
258 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
260 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
263 * Write PID file after dropping privileges. Added -F option
264 to run server on foreground. A patch by debolaz.
265 Affected files silcd/server.c, silcd/silcd.c.
267 * Fixed MOTD to return the MOTD file server name. Affected
268 file silcd/command.c.
270 * Added INFO command reply handling to the Irssi SILC Client.
271 Affected file irssi/src/silc/core/client_ops.c.
273 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
275 * Fixed the silc_idcache_list_* routines to really support
276 the dynamic list. Fixes a crash. Affected file is
277 lib/silccore/silcidcache.c.
279 * Fixed the LIST command reply to really call LIST command's
280 pending callbacks. Affected file silcd/command_reply.c.
282 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
284 * Update conn->local_entry->nickname after giving NICK
285 command. Affected file lib/silcclient/command.c.
287 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
289 * Added the [pid] option to the silcd configuration file
291 Affected files: serverconfig.[ch] and silcd.c
293 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
295 * Save fingerprint in WHOIS command reply in server.
296 Affected file silcd/command_reply.c.
298 * Fixed NICK commands pending callback registration.
299 Affected file lib/silcclient/command.c.
301 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
303 * Use ++server->cmd_ident when sending commands in server,
304 instead of random number. Affected file silcd/command.c.
306 * Fixed GETKEY command reply to call actually GETKEY pending
307 command callbacks. Affected file silcd/command_reply.c.
309 * A bit stricter check for nicknames. Check for same nickname
310 in NICK command also. Affected file silcd/command.c.
312 * Do not call INFO command everytime client ID changes, only
313 during first connecting. Affected file lib/silcclient/client.c.
315 * Set the new nickname only after successful command reply for
316 NICK command is returned by server. Affected file
317 lib/silcclient/command.c.
319 * Remove nicknames from nicklist during server_signoff notify.
320 Should fix /NAMES bit more. The affected file is
321 irssi/src/silc/core/silc-channels.c.
323 * Added `fingerprint' field to the SilcIDListData in the
324 silcd/idlist.h to hold the fingerprint of the client's
327 Send the fingerprint of the client's public key in WHOIS
330 Affected files silcd/command.c, and silcd/idlist.[ch].
332 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
333 create fingerprint from given data.
335 * Show the fingerprint of the client's public key in WHOIS.
336 Affected files irssi/src/module-formats.[ch] and
337 irssi/src/silc/core/client_ops.c.
339 * Format the multiple same nicknames also during JOIN and
340 NICK_CHANGE notifys. Affected file is
341 lib/silcclient/client_notify.c.
343 * Do not print error on screen for invalid private message
344 payload since it can come if someone is sending private
345 messages with wrong key. Affected file
346 lib/silccore/silcprivate.c.
348 * Fixed multiple concurrent /PING crash. Affected file
349 lib/silcclient/command.c.
351 * Changed the wrong ID encoding. All IP addresses must be
352 in MSB first order in encoded format. They were encoded
353 wrong and was in LSB format. Affected files are
354 silcd/serverid.c, lib/silcutil/silcutil.c.
356 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
358 * Call the `connect' client operation through the scheduler
359 in case of error. Affected file lib/silcclient/client.c.
361 * Call the `failure' client operation even if the error
362 occurred locally during a protocol. Affected file is
363 lib/silcclient/protocol.c.
365 * Added support of sending LIST command to router from normal
366 server. This way normal server can get list of all channels
367 in the network too. Fixed the channel list sending in the
368 server too. Affected files are silcd/command.c, and
369 silcd/command_reply.[ch].
371 * Added silc_server_update_channels_by_server and
372 silc_server_remove_channels_by_server. They are used during
373 disconnection of primary router and in backup router protocol.
374 Affected file silcd/server_util.[ch], silcd/server.c and
375 silcd/server_backup.c.
377 * Fixed channel adding to global list in IDENTIFY command
378 reply in server. Affected file silcd/command_reply.c.
380 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
382 * If the incoming packet type is REKEY or REKEY_DONE process
383 that packet always synchronously. Fixes yet another MAC
384 failed error on slow (dialup) connections. Affected file
385 lib/silcclient/client.c and silcd/server.c.
387 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
389 * Call check_version SKE callback for initiator too. Affected
390 file lib/silcske/silcske.c.
392 * Implemented fix for security hole found in the SKE that was
393 fixed in the specification few days back; the initiator's
394 public key is now added to the HASH value computation.
395 Added backwards support for the old way of doing it too, for
396 old clients and old servers. Affected file is
397 lib/silcske/silcske.c.
399 * Enabled mutual authentication by default in SKE. If initiator
400 is not providing mutual authentication the responder will
401 force it. This will provide the proof of posession of the
402 private key for responder. The affected files are
403 lib/silcclient/protocol.c and silcd/protocol.c.
405 * Do not cache anymore the server's public key during SKE.
406 We do mutual authentication so the proof of posession of
407 private key is done, and if the server is authenticated in
408 conn auth protocol with public key we must have the public
409 key already. Affected file silcd/protocol.c.
411 * Added new global debug variable: silc_debug_hexdump. If
412 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
413 file lib/silcutil/silclog.[ch].
415 * Fixed compilation warning due to char * -> const char *.
416 Affected files lib/silcutil/silcnet.h, and
417 lib/silccore/silcauth.[ch].
419 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Fixed CMODE command when new channel key was created. If
422 the creation failed the old key was removed. Next time giving
423 same command would crash the server since the old key was
424 freed already. Affected file silcd/command.c.
426 * Fixed the silc_server_announce_get_channels to not crash
427 on reconnect. Affected file silcd/server.c.
429 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Added silc_log_set_debug_string function to set a regex
432 string to match for debug output. Only the function names,
433 or filenames matching the given debug string is actually
434 printed. This way it is possible to filter out those debug
435 strings that user is not interested in.
437 Fixed a bug in silc_string_regexify.
439 Affected files lib/silcutil/silclog.[ch], and
440 lib/silcutil/unix/silcunixutil.c.
442 * Changed the -d options in both server and Irssi SILC client
443 to take the debug string as argument. Affected files
444 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
446 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
448 * Added silc_hash_babbleprint to create a Bubble Babble
449 Encoded fingerprint. The encoding is developed by Antti
450 Huima (draft-huima-babble-01.txt), and it creates human
451 readable strings out of binary data. Affected file
452 lib/silccrypt/silchash.[ch].
454 * Print the babble print now in addition of fingerprint as well
455 in Irssi SILC client. Affected files are
456 irssi/src/fe-common/silc/module-formats.[ch],
457 irssi/src/fe-common/silc/core/client_ops.c.
459 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
461 * Fixed a security problem found in SKE. The initiator's
462 public key too is now added to the HASH hash value creation
463 which is signed by the responder to create the SIGN value.
464 This will prevent anyone in the middle to lie to the responder
465 about the initiator's public key. If this is done now, the
466 man in the middle will get caught. Updated the protocol
469 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
471 * Better installation directory handling. Configure module
472 paths and other paths automatically to example_silc* files
473 in doc/. A patch by toma.
475 * Fixed compiler warning from MPI library, and from SILC RNG.
478 * Added SILC_SERVER_PID_FILE to define the pid file for server.
479 It can be configured with ./configure. A patch by toma.
481 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Find correct make to use in prepare-clean. A patch by
484 toma. Affected file prepare-clean.
486 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
488 * Added irssi variables use_auto_addr, auto_bind_ip,
489 auto_bind_port and auto_public_ip.
491 * Changed the interface for silc_client_send_key_agreement
492 in lib/silcclient/silcapi.h
496 irssi/src/silc/core/silc-core.c
498 lib/silcclient/silcapi.h
499 irssi/src/silc/core/silc-channels.c
500 lib/silcclient/client_keyagr.c
503 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
505 * Added silc_pkcs_public_key_compare to compare two
506 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
508 * Check that the client who set the founder mode on the
509 channel is the same client that is giving the founder
510 mode to itself. It is done by comparing the saved public
511 key (it is saved even in the authentication is passphrase).
512 Affected file silcd/command.c.
514 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
516 * Do not process packet for disconnected socket connection.
517 Affected file lib/silccore/silcpacket.c.
519 * Process the DISCONNECT packet through scheduler in the
520 client library. Affected file lib/silcclient/client.c.
522 * Fixed the silc_client_packet_parse to not to increase
523 the packet sequence number if the conn->sock and the
524 current socket connection is not same. This can happen
525 for example during key agreement when the conn includes
526 multiple socket connections (listeners). Affected file
527 lib/silcclient/client.c.
529 * The sender of the file transfer request now provides also
530 the pointer (listener) for the key exchange protocol. If
531 the listener cannot be created then it sends empty key
532 agreement and lets the receiver provide the listener.
534 Added `local_ip' and `local_port' arguments to the
535 silc_client_file_send. If they are provided they are used,
536 if not then it will attempt to find local IP address, if
537 not found or bind fails then the remote client will provide
540 Affected files are lib/silcclient/client_ftp.c and
541 lib/silcclient/silcapi.h.
543 * Extended the FILE SEND command to support defining the
544 local IP and port for key exchange listener. They are
545 optional. Affected file irssi/src/silc/core/silc-servers.c.
547 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
549 * Defined to WHOIS command reply the sending of fingerprint
550 of the client's public key (if the proof of posession of the
551 corresponding private key is verified by the server).
552 Updated to the protocol specification.
554 * Added support of receiving the client's public key's
555 fingerprint in command reply in client library. Affected
556 file is lib/silcclient/command_reply.c, and
557 lib/silcclient/idlist.[ch].
559 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Do not send over 128 chars long nickname to the server
562 in NICK command. Affected file lib/silcclient/command.c.
564 * Do not send over 256 chars long channel names to the server
565 in JOIN command. Affected file lib/silcclient/command.c.
567 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>

615 during SERVER_SIGNOFF, but invalidate it. This way we
616 preserve the WHOWAS info for the client. Affected file
619 * Fixed SERVER_SIGNOFF notify handling in the server. The
620 server is now able to process incoming SERVER_SIGNOFF notify
621 for a server that it doesn't even know about. It will remove
622 the clients provided in the notify. Affected file
623 silcd/packet_receive.c.
625 * Check for partial packet in data queue after every packet that

664 if make install is given. Affected files: all Makefile.am's.
666 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
668 * Assure that silc_client_notify_by_server_resolve does not
669 resolve the client information multiple times. If it cannot
670 be found by the first it cannot be found at all. Affected
671 file lib/silcclient/client_notify.c.
673 * Fixed WHOWAS command reply calling. Affected file
674 lib/silcclient/command_reply.c.
676 * Removed all references to silc_idlist_get_client from the
677 Irssi SILC client since that call is internal call used by
678 the library. The Irssi SILC client will use now client
679 retrieval functions found in silcapi.h.
681 * Fixed a bug in resolving nickname info before sending
682 private message. It used freed memory. Affected file
683 irssi/src/silc/core/silc-servers.c.
685 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

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

798 * Redefined the SILC packet header to include the padding
799 length. Affected file lib/silccore/silcpacket.[ch].
801 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
802 length for maximum padding up to 128 bytes). Affected
803 file lib/silccore/silcpacket.h.
805 * Removed all backwards support for old 0.5.x MAC thingies.
806 The SILC packet header change makes it impossible to be
807 backwards compatible.
809 * Send the ENDING packet with timeout in the backup resuming
810 protocol. This is to assure that all routers has connected
811 to the primary router. Affected file silcd/server_backup.c.
813 * Changed the RNG to take the first IV from random data. It
814 used to take it from zero actually. Changed the RNG also
815 to use /dev/urandom during session. /dev/random is used
816 in initialization. Affected file lib/silccrypt/silcrng.[ch].
818 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
820 * Changed the SILC packet header to have the first two bytes
821 (the packet length) encrypted. Affected files aroung the
822 code tree, lib/silccore/silcpacket.[ch]. Removed the
823 SilcPacketCheckDecrypt callback. It is not needed anymore
824 since the silc_packet_receive_process will determine now
825 whether the packet is normal or special.
827 * Implemented the unidirectional MAC keys. Affected files
828 lib/silcske/silcske.c, silcd/protocol.c and
829 lib/silcclient/protocol.c.
831 * Implemented the packet sequence number to the MAC computation.
832 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
833 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
834 lib/silcclient/protocol.c.
836 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Allow backup router to announce servers. All servers
839 announced by backup router are added to the global list
840 automatically. Update hte server's socket to our primary
841 router also when backup router announces a server.
842 Affected file silcd/packet_receive.c.
844 * Do not update the client->router in the function
845 silc_server_udpate_clients_by_server if the client is on
846 global list. We might fail to find any specific server
847 for locally connected clients and local cell clients. They
848 should still use the `from' and not `to' as client->router.
849 This fixes backup router resuming protocol. Affected file
852 * Decrease channel statistics count only if the channel
853 deletion worked. Affected files are silcd/server.c and
856 * Added silc_server_update_servers_by_server to update origin
857 of all server entries. Used during backup router protocol.
858 Affected files silcd/server_util.[ch], silcd/server.c. and
859 silcd/backup_router.c.
861 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
862 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
863 silc_hmac_get_hash and silc_hmac_get_name. Affected file
864 lib/silccrypt/silchmac.c.
866 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
868 * Assure that router cannot reroute the same channel message
869 to the sender. Affected file silcd/packet_receive.c.
871 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
873 * Made better checks that the channel message is not sent
874 to the router it came from. Affected file is
875 silcd/packet_send.c. Fixed memory leak too.
877 * Announce informations for incoming router connection, but
878 only after checking if it is replaced by backup router.

884 router environment. Affected file silcd/server_backup.c.
886 * Route packet only to one router in the function
887 silc_server_packet_send_to_channel. Affected file is
890 * Fixed silc_server_send_notify_dest to set the broadcast
891 flag. Fixed the silc_server_send_notify_topic to actually
892 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
893 Affected file silcd/packet_send.c.
895 * Changed the SFTP Filesystem interface. Changed the
896 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
897 the filesystem operation function. The SilcSFTPFilesystem
898 is now a context that is allocated by all filesystem allocation
899 functions and it already includes the operations structure
900 and filesystem specific context. It is given as argument
901 now to the silc_sftp_server_start. This made the interface
902 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
903 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
905 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
907 * Changed the backup router adding and getting interfaces
908 in the server. The router that will be replaced by the
909 specified backup router is now sent as argument. Affected
910 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
913 * Added silc_net_addr2bin_ne to return the binary form of
914 the IP address in network byte order. Affected files
915 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
917 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
919 * Check for existing server ID in silc_server_new_server
920 and in silc_server_connect_to_router_final and remove the
921 old entry if it exists. Affected file silcd/packet_receive.c,

931 protocol specification.
933 * Removed one redundant channel key generation from normal
934 server during joining procedure. Removed one redundant
935 channel key sending from server to router during joining
936 procedure. Affected file silcd/command.c.
938 * Made minor bugfixes to the backup router resuming protocol.
939 Affected file silcd/server_backup.c, server.c.
941 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

961 * Assure that if outgoing data buffer is pending do not force
962 send any data. Affected file lib/silcclient/client.c.
964 * Implemented the backup router support when the primary router
965 goes down. The servers and routers can now use the backup
966 router as new primary router without loosing connectivity.
968 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
970 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
971 in the server to indicate disabled entry. All data read
972 from the connection will be ignored and no data is sent
973 for entry that is disabled. Affected files are
974 silcd/idlist.h, silcd/server.c.
976 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Created SFTP client and server test programs in the
979 lib/silcsftp/tests directory.
981 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
983 * Implemented memory filesystem (virtual filesystem) for
984 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
987 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Implemented the SFTP (SSH File Transfer Protocol) to the
990 lib/silcsftp. It includes SFTP client and SFTP server
993 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
995 * Moved lib/silccore/silcprotocol.[ch] to the
996 lib/silcutil library.
998 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
999 take variable argument list pointer as argument. Affected
1000 file lib/silcutil/silcbuffmt.[ch].
1002 * Added silc_buffer_set function that is used to set data
1003 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1004 Affected file lib/silcutil/silcbuffer.h.
1006 * Changed various routines in the core library to use the new
1007 silc_buffer_set instead of allocating new buffer only for
1010 * Added 64-bit value formatting and unformatting support to the
1011 silc_buffer_[un]format routines. Affected file is
1012 lib/silcutil/silcbuffmt.[ch].
1014 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1015 to includes/bitmove.h.
1017 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Fixed channel user mode saving in client library. Affected
1020 file lib/silcclient/command[_reply].c.
1022 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Defined the file transfer to the SILC Protocol. Added
1025 new packet type SILC_PACKET_FTP and defined File Transfer
1026 Payload. The mandatory file transfer protocol is SFTP
1027 (SSH File Transfer Protocol). Affected file in addition
1028 of the internet draft is lib/silccore/silcpacket.h.
1030 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1031 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1032 is used as part of backup router protocol when the primary
1033 router of the cell is back online and wishes to resume
1034 the position as primary router.
1036 * Redefined the MAC generation keys in the protocol. The
1037 same key is not used anymore in both direction. Both
1038 direction will now use different keys for sending and
1039 receiving. This fixes a potential security flaw. This
1040 change causes incompatibilities in the protocol.
1042 * Redefined also the MAC computation from the packet.
1043 An packet sequence number is now added to the MAC
1044 computation. This prevents possible replay attacks against
1045 the protocol. This change too causes incompatibilities
1048 Added `sequence' field to the SilcPacketContext to hold
1049 the current sequence number for the packet.
1051 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Added `created' field to the SilcIDListData in the file
1054 silcd/idlist.h to indicate the time when the entry was
1057 * Added `created' field to the SilcChannelEntry too. Affected
1058 file silcd/idlist.h.
1060 * Added `creation_time' aguments to all the announcement functions
1061 in the server. If it is provided then only the entries that
1062 was created after the provided time frame are actually
1063 announced. Affected file silcd/server.[ch].
1065 * The protocol says that the Channel ID's IP address must be
1066 based on the router's IP address. Added check for this in
1067 the silc_server_new_channel when processing incoming New Channel
1068 Payload. Affected file silcd/packet_receive.c.
1070 * Print out the correct version with --version in SILC client.
1071 Affected file irssi/src/silc/core/silc-core.c.

1076 entry always, not just when the command is coming from client.
1077 Affected file silcd/command.c.
1079 * Added new function silc_server_packet_queue_purge to purge the
1080 outgoing data queue to the network. After the function returns
1081 it is guaranteed that the outgoing packet queue is empty.
1082 Affected file silcd/packet_send.[ch].
1084 * Purge the outgoing packet queue in the rekey protocol's final
1085 callback to assure that all rekey packets go to the network
1086 before quitting the protocol. Affected file silcd/server.c.
1088 * Added silc_client_packet_queue_parse as similar function as
1089 in server to the client library. The affected file is
1090 lib/silcclient/client.c.
1092 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Splitted silcd/server.c and created silcd/server_util.[ch]
1095 for utility functions.
1097 * Added new socket flag SILC_SF_DISABLED to indicate that the
1098 connection is open but nothing can be sent to or received from
1099 the connection. Affected file lib/silcutil/silsockconn.[ch].
1100 The checking for disabled socket is checked in the low level
1101 silc_socket_write and silc_socket_read functions.
1103 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Allow only nicknames and channel names that fits into the
1106 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1108 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1110 * When processing JOIN command reply in server check that if
1111 the channel exists in our global list we'll move it the local
1112 list. Affected file silcd/command_reply.c.
1114 * Fixed the check whether client is joined on the channel already
1115 in JOIN command. Affected file lib/silcclient/command.c.
1117 * Fixed the JOIN command reply to check whether the channel
1118 already exists. Affected file lib/silcclient/command_reply.c.
1120 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Added silc_ske_status_string to map the SKE error numbers
1123 to readable strings. The affected files are
1124 lib/silcske/silcske[_status].[ch].
1126 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Do not show the private channels on the WHOIS channel list
1129 as it is not allowed by the protocol. The affected file is
1132 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Assure that the packet length digged from the actual packet
1135 is something sensible in the silc_packet_decrypt_rest_special
1136 in lib/silccrypt/silcpacket.c.
1138 * Free and NULL the allocated pointer in silc_hmac_alloc if
1139 the HMAC allocation fails. The affected file is
1140 lib/silccrypt/silchmac.c.
1142 * Print the selected security properties to the log files in
1143 the server. Affected file silcd/protocol.c.
1145 * Add SKE's reference counter even if calling the completion
1146 callback manually. Otherwise it goes negative, although it
1147 does not cause any problems. The affected file is
1148 lib/silcske/silcske.c.
1150 * Remove the client entry with short timeout after giving the
1151 KILL command. Affected file lib/silcclient/command.c.
1153 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1154 case all found clients are already disconnected (WHOWAS would
1155 found them) in the server. Affected file silcd/command.c.
1157 * Update the last_receive (time of last data received) to be
1158 updated only when received private or channel message so that
1159 the idle time showed in WHOIS makes more sense.
1161 * Added boolean field `valid' in to the SilcClientEntry in the
1162 client library to indicate whether the entry is valid or not.
1163 This fixes the nickname change bug on channel when changing
1164 the nickname to be same than the old (like nick to Nick) the
1165 nickname formatter doesn't set the new nick anymore to Nick@host.
1166 Affected file lib/silcclient/idlist.[ch].
1168 * Now actually fixed the nickname changing on disconnection.
1169 Added new function silc_change_nick to the Irssi SILC Client.
1170 Affected file irssi/src/silc/core/client_ops.c,
1171 irssi/src/silc/core/silc-nicklist.[ch].
1173 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1175 * Check that the public key exists in the GETKEY command before
1176 trying to encode it. Affected file silcd/command.c.
1178 * Print some notifications on received public keys with GETKEY
1179 command in the Irssi SILC Client. Affected files are
1180 irssi/src/fe-common/silc/module-formats.[ch],
1181 irssi/src/silc/core/client_ops.c.
1183 * Use IDENTIFY command to resolve the server information in the
1184 GETKEY command instead of INFO command. Affected file
1185 lib/silcclient/command.c.
1187 * All command reply functions in the client library now calls
1188 the pending command reply callbacks even if an error has
1189 occurred. The server has done this a long time and now it was
1190 time to move the client library to this as well. Now all
1191 errors can be delivered back to the pending command reply
1192 callbacks if necessary. Affected files are
1193 lib/silcclient/command[_reply].[ch].
1195 * Change the nickname on disconnection back to the username
1196 because in reconnect the server will enforce it to it anyway.
1197 Affected file irssi/src/silc/core/silc-servers.c.
1199 * Fixed a config file parsing bug in the Irssi SILC client.
1200 Affected file irssi/src/silc/core/clientconfig.c.
1202 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * When printing the channel mode on JOIN, verify that the
1205 channel key and channel's HMAC are valid. Affected file
1206 irssi/src/silc/core/client_ops.c.
1208 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1211 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1212 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1214 * Removed channel key rekey task deleting from the function
1215 silc_server_save_channel_key. Affected file silcd/server.c.
1216 Added explicit timeout task context instead that is used to
1217 delete the task if we are registering a new task before the
1218 new task has elapsed.
1220 * When channel key rekey occurs the client library now saves
1221 the old channel key for a short period of time (10 seconds) and
1222 is able to use it in case some is still sending channel
1223 messages encrypted with the old key after the rekey. Affected
1224 file lib/silcclient/[idlist.h|client_channel.c].
1226 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Added check to the silc_server_new_id_real to not accept
1229 new ID if it is the sender's own ID. Affected file is
1230 silcd/packet_receive.c.
1232 * Assure that we do not announce ourself or the one we've
1233 sending our announcements when we're router and are announcing
1234 servers to our primary router. Affected file silcd/server.c.
1236 * Fixed silc_server_command_identify_check_client to assemble
1237 correct WHOIS packet. It send corrupted WHOIS packet and
1238 caused problem with router to router connections. Affected
1239 file silcd/command.c.
1241 Fixed also silc_server_command_whois_check the same way
1242 as for the IDENTIFY command.
1244 * Added new SilcIDListStatus to the server in the SilcIDListData
1245 structure. The status now includes the current status of
1246 the entry (like registered, resolved etc.). Affected file
1247 silcd/idlist.[ch]. Defined a bunch of different status types
1248 as well. This replaced the old boolean registered field as well.
1250 Added resolve_cmd_ident field to the SilcClientEntry structure
1251 too so that if the entry is for example being resolved so
1252 another command may attach to the same pending command reply
1253 without requiring to resolve the same entry again. This concept
1254 should optimize the WHOIS and the IDENTIFY resolving under
1255 heavy load by taking away unnecessary resolving for entries
1256 that are being resolved already.
1258 Added support for adding multiple pending commands for one
1259 command idenfier. Affected file silcd/command[_reply].[ch].
1261 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1262 before deleting the data. Otherwise the hash table will have
1263 freed data in comparison functions. Affected file is
1264 silcd/command_reply.c.
1266 * Fixed silc_idlist_replace_client_id to add the new entry to
1267 the cache with NULL nickname. Otherwise there will be invalid
1268 memory as the nickname after the nickname is freed. Affected
1269 file silcd/packet_receive.c.
1271 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1272 saved into wrong slots because the previous number of entries
1273 was not taken into account. Affected file silcd/idlist.c.
1274 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1276 * If we are router and we receive JOIN notify to a channel that
1277 does not have any users then notified client is marked as the
1278 channel founder, as it is it. The affected file is
1279 silcd/packet_receive.c
1281 * Added to the extended hash table API's table_del_*ext functions
1282 the destructor as argument too, so that the caller can decide
1283 which destructor to use or whether to use destructor at all.
1284 Affected file lib/silcutil/silchashtable.[ch].
1286 * Fixed ID Cache purging. It actually deleted the entries from
1287 the hash table after the data was freed. The hash table ended
1288 up comparing freed memory. The affected file is
1289 lib/silccore/silcidcache.c.
1291 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1293 * Fixed Irssi SILC client's KILL command's HELP syntax.
1295 * The USERS command now resolves the detailed user information
1296 if the userinfo field is missing. Affected file is
1297 lib/silcclient/command_reply.c.
1299 * Do not print error in silc_file_read if the read file does
1300 not exist. Just silently return NULL. Affected file is
1301 lib/silcutil/silcutil.c.
1303 * Fixed the silc_log_output to not wine about NULL filename
1304 and to not create some bogus " " filename. Affected file is
1305 lib/silcutil/silclog.c.
1307 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Fixed various printing bugs on the user interface in the
1310 Irssi SILC Client. Minor changes that were forgotten from
1313 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Fixed the configure.in.pre and the compilation and distribution
1316 environment to support the new autoconf 2.52. That version is
1317 now required to compile the CVS trunk.
1319 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1322 to generally parse user@fqdn format strings. Affected file
1323 lib/silcutil/silcutil.c.
1325 * Added nickname_format and nickname_force_format fields to the
1326 SilcClientParams structure. The first one defines the format
1327 for the nicknames that the library will enforce if the receives
1328 multiple same nicknames. The second one is boolean value and
1329 can be used to force the library to always enforce the format
1330 to the nicknames regardles whether there are multiple nicknames
1331 or not. This configurable formatting was employed to flexibly
1332 support accessing multiple nicknames from the user interface.
1333 The userinterface can now set the nicknames to what ever format
1334 they prefer. Affected file lib/silcclient/silcapi.h.
1336 Added function silc_client_nickname_format to the file
1337 lib/silcclient/idlist.c. It performs the nickname formatting.
1339 Added new field `hostname´ to the SilcClientEntry context.
1340 It holds the hostname of the client. Affected file is
1341 lib/silcclient/idlist.h.
1343 * Irssi SILC Client sets the nicknames in nick@hostn format.
1344 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1345 irssi/src/silc/core/silc-core.c.
1347 The WHOIS printing now also shows both the real nickname and
1348 the formatted nickname so that user knows how to access the
1349 user if there are multiple same nicknames cached. Affected
1350 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1351 printing formatting too to take the hostname now as a separate
1352 argument. The Affected file is
1353 irssi/src/fe-common/silc/modules-formats.[ch].
1355 * Changed the silc_client_get_clients_local to accept the formatted
1356 nickname as argument. It accepts the real nickname too but the
1357 formatted nickname can be used to find the true entry from
1358 multiple entries. Affected file lib/silcclient/silcapi.h and
1359 lib/silcclient/idlist.c.
1361 * Added nickname_format_parse field to the SilcClientParams.
1362 It is a callback function provided by the application to parse
1363 the nickname out of the formatted nickname string. The library
1364 calls it to get the nickname from the formatted string. Since
1365 the application generally knows better the format of the nickname
1366 string it parses it instead of the library, even though library
1367 encodes the formatted string. If the callback function is not
1368 provided then the library will use the string as is. The
1369 affected file is lib/silcclient/silcapi.h.
1371 * All the nickname strings passed to the client library in
1372 commands are now expected to be formatted nickname strings.
1373 If the command does not support the formatted nickname string
1374 it will assume that the sent string is the actual nickname.
1375 Affected file lib/silcclient/command.c.
1377 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Added public key authentication support to OPER and SILCOPER
1380 commands in the client library. Affected file is
1381 lib/silcclient/command.c.
1383 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Changed the get_auth_methdod client operation to be asynchronous.
1386 It can be async if the application resolves the authentication
1387 method from the server during the negotiation. Added new
1388 SilcGetAuthMeth completion callback that the application will
1389 call after resolving the authentication method.
1391 Added function silc_client_request_authentication_method that
1392 the application can use to resolve the authentication method
1393 from the server. Added also SilcConnectionAuthRequest callback
1394 that the library will call after the server has replied. The
1395 application can call this function if it does not know the
1396 current authentication method.
1398 Affected files are lib/silcclient/client.c and
1399 lib/silcclient/silcapi.h.
1401 * The Irssi SILC client now automatically resolves the authentication
1402 method incase any configuration information is not present (and
1403 currently there never is). The affected file is
1404 irssi/src/silc/core/client_ops.c.
1406 * Fixed public key authentication from the client library.
1407 Affected file lib/silcclient/protocol.c. Changed also the
1408 protocol specification about the public key authentication in
1409 the connection authentication protocol. The actual data to be
1410 signed is now computed with a hash function before signing.
1412 * Fixed the public key authentication from the server as well.
1413 Affected file silcd/protocol.c.
1415 * Removed the mlock()'s from the memory allocation routines.
1416 Affected file lib/silcutil/silcmemory.c. The ./configure does
1417 not check anymore for the mlock(). Affected file is
1420 * Fixed USERS command in server to allow the execution of the
1421 command for private and secret channels if the client sending
1422 the command is on the channel. Affected file silcd/command.c.
1424 * Fixed silc_client_get_clients_local to return the clients
1425 count correctly. It could return wrong value. Affected file
1426 lib/silcclient/idlist.c.
1428 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1431 types. The assembler optimizations seemed not to like 64-bit
1432 data types. The assmebler optimizations thus are now enabled
1433 also for BSD systems as opposed to only enable them for Linux.
1435 * Do not check for threads at all on BSD systems. Affected
1436 file configure.in.pre.
1438 * Removed -n and -h options from the Irssi SILC Client since
1439 they are not used in silc.
1441 * Fixed the prime generation to assure that the first digit
1442 of the generated random number is not zero since our conversion
1443 routines does not like number strings that starts with zero
1444 digit. If zero digit is seen the random number is regenerated.
1445 This caused some corrupted RSA keys when the zero first digit
1446 was met. Affected file lib/silcmath/silcprimegen.c.
1448 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Fixed WIN32 configuration in the ./configure script.
1451 Fixed to include xti.h on environments that has it.
1452 Patches by Carsten Ilchmann and andrew.
1454 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Changed the silc_id_create_client_id to be collision
1457 resistant. It is now assured that there cannot be created
1458 two same client ID's. I suspect that some weird bugs in
1459 the server were actually caused by duplicate Client IDs.
1460 Affected file silcd/serverid.[ch]. A router receiving
1461 new ID now also assures and informs the sending server
1462 if the ID caused collision.
1464 * Changed the silc_id_create_channel_id to also assure that
1465 there are no collisions.
1467 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Statement about ignoring the Mutual Authentication flag when
1470 performing rekey with PFS was a bit misleading. It is ignored
1471 if it was set in the initial negotiation, it cannot be even
1472 set in the rekey. Fixed in the ke-auth draft. Started the
1473 new versions of the protocol drafts in the doc/.
1475 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Fixed a bug in silc_client_command_identify_save when saving
1478 new channel information. The channel name was no duplicated
1479 and caused crash on exit. Affected file is
1480 lib/silcclient/command_reply.c.
1482 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Fixed the getkey command handling in the server. Send just
1485 empty OK reply to the sender if the key could not be fetched
1486 (but everything else was ok, like the key just was not available).
1487 Changed the public key parameter to optional in the protocol
1488 specs so that empty OK reply can be sent. Affected file
1491 Added a message to Irssi SILC client to tell to user if the
1492 server did not return a public key.
1494 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Fixed a channel key regeneration bug. It registered new
1497 timeout tasks exponentially until all system resources were
1498 used. Affected file silcd/server.c.
1500 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Added the SILC Document generator to the scripts/silcdoc.
1503 It can be used to generate the Toolkit Reference Manual out
1504 of the source tree. Internally it will also use the RoboDoc
1505 generator now imported in util/robodoc.
1507 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Added couple of return's in rekey protocol if error orccurred
1510 during the protocol. The execution must be terminated.
1511 Affected file silcd/protocol.c. Also, terminate the protocol
1512 always with timeout.
1514 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * The client's Client ID was created initally from the wrong
1517 nickname (it could have been in format nick@host) in the
1518 silc_server_new_client. Affected file silcd/packet_receive.c
1520 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1522 * Added some SILC_LOG_ERROR's to various error conditions
1523 if client could not be added to ID cache. Affected files
1524 silcd/packet_receive.c and silcd/server.c.
1526 * When client's sock->user_data is freed, NULL also the
1527 client->router and client->connection pointers. Added check
1528 for these pointers being NULL to various places around the
1529 code. Affected file silcd/server.c.
1531 * Added client->data.registered == TRUE checks to various
1532 places around the code to assure that unregistered client's
1533 are not handled when it is not allowed. Affected file
1536 * Added `bool registered' fields to all
1537 silc_idlist_[server|client]_get_* routines to indicate whether
1538 the fetched client needs to be registered or not. Affected
1539 file silcd/idlist.[ch].
1541 * Add your own entry as registered to the ID cache in the
1542 server. Affected file server.c.
1544 * Fixed a bug in silc_server_new_server. The SilcServer was
1545 set as the new server's context instead of SilcServerEntry.
1546 This naturally caused some weird bugs.
1548 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Do not delete the channel rekey task when adding it
1551 for in silc_server_create_channel_key.
1553 * Changed the silc_server_create_channel_key to return
1554 TRUE or FALSE to indicate the success of the channel key
1557 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Fixed MSVC++ project files and added missing files to
1560 Makefiles under win32/.
1562 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Do not add TCP_NODELAY flag if the operating system
1565 does not have it defined. Affected files are
1566 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1568 * Fixed buffer overflow from Irssi SILC Client. Affected
1569 file irssi/src/fe-common/core/themes.c.
1571 * Fixed double free in client library in the file
1572 lib/silcclient/client.c when disconnecting from server.
1574 * Applied double free patch from cras to Irssi SILC client.
1575 Affected files irssi/src/core/[modules/expandos].c
1577 * Fixed the disconnection handling to Irssi SILC Client.
1578 The application must call silc_client_close_connection
1579 in ops->connect client operation in case of failure of
1580 the connection. Affected file is
1581 irssi/src/silc/core/client_ops.c.
1583 * Do not set sock->protocol to NULL in the function
1584 silc_client_close_connection after executing the protocol's
1585 final callback since the sock might not be valid anymore.
1586 Affected file lib/silcclient/client.c.
1588 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1590 * Do not enable SILC_THREADS if the linking with libpthread
1591 did not happen. Affected file configure.in.pre.
1593 * Added notion to protocol specification that server must
1594 verify the sent authentication payload with CMODE when
1595 setting the channel founder key. Implemented it to the
1596 server. Affected file silcd/command.c.
1598 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Added _EXTRA_DIST SILC distribution variable to the
1601 distributions file. It is used to conditionally add extra
1602 files or directories to the specific distribution. Affected
1603 files ./prepare, Makefile.am.pre and distributions.
1605 Removed the `_' from the start of the distribution names.
1608 * Added README.WIN32 for instructions to compile the Toolkit
1611 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Fixed a double free in disconnection in the server. Affected
1614 file is silcd/server.c.
1616 * Fixed the lib/silcske/groups.c to work now also with GMP
1617 MP library. The string conversion did not work when using
1618 specific base and the base is indicated in the string as well.
1620 * Created win32/ directory which now includes MSVC++ specific
1621 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1622 It will appear only in the toolkit distribution
1624 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Changed the key material distribution function in case when
1627 the hash output is too short. The data is now concatenated
1628 a bit differently than it used to. Made the change to the
1629 SKE protocol specification.
1631 * Added better GMP detection to configure.in.pre. A patch
1634 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Fixed a minor bug in SKE that might cause some problem on
1637 some platforms. Affected file lib/silcske/silcske.c.
1639 * Added the cookie checking for initiator in the SKE. It checks
1640 that the responder returns the sent cookie unmodified. The
1641 affected file is lib/silcske/silcske.c. Added new SKE
1642 error type INVALID_COOKIE that can be sent during the
1643 negotiation. Fixed some memory leaks as well.
1645 * Added the "invalid cookie" error message to Irssi SILC client's
1648 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Added `task_max' field to the SilcClientParams to indicate
1651 the maximum tasks the scheduler can handle. If set to zero,
1652 default values are used. Affected file lib/silcclient/silcapi.h.
1654 * Fixed memory leaks in silc_client_close_connection. Affected
1655 file lib/silcclient/client.c.
1657 * Added silc_client_del_client_entry to client library to free
1658 all memory of given client entry. Affected file is
1659 lib/silcclient/idlist.[ch].
1661 * Added new functions silc_client_del_channel and
1662 silc_client_del_server to delete channel and server entries.
1663 Affected file lib/silcclient/[silcapi.h/idlist.c].
1665 * Removed silc_client_del_client_by_id from silcapi.h.
1667 * Fixed the INFO command to return the server's own info
1668 correctly when querying by Server ID. Affected file is
1671 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Removed the non-blocking settings in WIN32 code in the
1674 silc_sock_[read/write] and added SleepEx instead. Affected
1675 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1676 of input data is now checked with FIONREAD and ioctlsocket.
1678 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * Call silc_schedule_task_del_by_context in the
1681 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1682 Affected file lib/silccore/silcprotocol.c.
1684 * Call silc_protocol_cancel for active protocols in the
1685 silc_server_close_connection if the funtion
1686 silc_server_free_sock_user_data has not been called.
1687 Affected file silcd/server.c.
1689 * Generic tasks cannot be deleted using the del_by_fd
1690 task deleting function since generic tasks does not match
1691 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1693 * Added a notion to SILCOPER help file that the SILCOPER works
1694 only on router server, not on normal server.
1696 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Added for WIN32 support for the new scheduler as well.
1699 Affected file lib/silcutil/win32/silcwin32schedule.c.
1701 * Fixed the SHA1 implementation to work on various platforms.
1703 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1706 API. It is part of the scheduler now. Everything else is
1707 as previously but some functions has changed their names.
1708 Checkout the lib/silcutil/silcschedule.h for the interface.
1709 Updated all applications to use the new interface. Affected
1710 files are lib/silcutil/silcschedule.[ch].
1712 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1714 * Found a bug in the SKE implementation. The HASH value,
1715 specified by the protocol, was not computed correctly. The
1716 public key of the responder was not added to the computation
1717 even though it is mandatory. Affected file lib/silcske/silcske.c.
1718 This unfortunately causes incompatibilities with older
1719 clients and servers.
1721 * Added WIN32 specific network init and uninit functions:
1722 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1723 the Winsock2. Affected file lib/silcutil/silcnet.h and
1724 lib/silcutil/win32/silcwin32net.c.
1726 * Set the socket always to nonblocking mode on WIN32 after
1727 reading data or writing data. Affected file is
1728 lib/silcutil/win32/silcwin32sockconn.c.
1730 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Fixed various compilation problems under WIN32. Affected
1733 files lib/silcutil/win32/silcwin32thread.c and
1734 lib/silcutil/win32/silcwin32schedule.c.
1736 * Removed all _internal.h #includes from public header
1737 files. Internal headers must never be included from
1740 Removed also the lib/silcske/payload_internal.h file.
1742 * All include files that may be needed (public and some others
1743 included by the public headers) by application developers are
1744 now copied to the ./includes directory. It does not copy any
1745 internal headers. Affected file Makefile.defines.pre and all
1746 Makefile.am's under lib/ and subdirs.
1748 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Do not change the ~/.silc directory's permissions automatically.
1751 Affected file irssi/src/silc/core/clientutil.c.
1753 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Do not cancel the protocol in silc_server_close_connection
1756 it might cause recursion. Now cancelled in the function
1757 silc_server_free_sock_user_data. Affected file silcd/server.c.
1759 * Fixed the silc_server_remove_clients_by_server to regenerate
1760 the channel keys correctly finally. Added also new function
1761 silc_server_remove_clients_channels to actually do it.
1762 Affected file silcd/server.c.
1764 * Fixed the silc_server_new_channel to not crash by giving
1765 wrong router to the new channel. Affected file is
1766 silcd/packet_receive.c.
1768 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1770 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1771 which is given as argument to the silc_client_alloc now.
1772 It can be used to configure the client and set various parameters
1773 that affect the function of the client.
1775 * The USERS command in server did not check whether the channel
1776 is private or secret. Affected file silcd/command.c.
1778 * Added new argument to the USERS command in protocol specification.
1779 The USERS command now can take the channel name as argument
1780 as well. Added support for this in client and server and
1781 updated the protocol specs.
1783 * Completed the GETKEY command in client. It can be now used
1784 to fetch also servers public key not only some clients.
1785 Affected files lib/silcclient/command[_reply].c.
1787 * Added silc_client_get_server to return server entry by the
1788 server name. Affected files lib/silcclient/silcapi.h and
1791 * Redefined the IDENTIFY command in protocol specification to be
1792 more generic. It now can be used to query information about
1793 any entity in the SILC Network, including clients, servers and
1794 channels. The query may be based either the entity's name
1795 or the ID. Added support for this in both client and server.
1797 Affected files silcd/command.c and lib/silcclient/command.c
1798 and command_reply.c.
1800 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1801 the _from_client and _from_server functions. Affected file
1804 * Added silc_client_get_channel_by_id_resolve to the file
1805 lib/silcclient/silcapi.h to resolve channel information by
1806 its ID. Added also silc_client_get_channel_by_id that
1807 does not resolve it from the server.
1809 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Added SilcServerEntry context into the client library
1812 to represent one server. The INFO command now allocates
1813 these to save the resolved server info. For now on the
1814 client library will also keep information about servers,
1815 connected and resolved with INFO.
1817 The INFO command now allocates the SilcServerEntry context
1818 and saves the server info there. The COMMAND_REPLY in
1819 the INFO now returns the parameters to application in
1820 same order as defined in the protocol specification.
1822 The entries are cached in the client->server_cache.
1824 * The INFO command is now issued after received the Client ID
1825 from the server. Affected file lib/silcclient/client.c.
1827 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1828 to the application as the mode changer might be server.
1829 It is guaranteed that NULL is not returned anymore to the
1830 application. Affected file lib/silcclient/client_notify.c.
1832 The ID Type is now also passed to the application so that
1833 it can check whether the returned entry is SilcClientEntry
1836 Added new function silc_client_get_server_by_id to return
1837 the server entry by ID. Affected files are the
1838 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1840 * Do not create the channel in the Irssi SILC Client when issuing
1841 the JOIN command but when received the sucessful JOIN command
1842 reply. Otherwise the channel might get created even though we
1843 could not join it. The Affected file is
1844 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1846 * Fixed a channel joining bug in router. The router must also
1847 check the channel modes, invite and ban lists etc. when serving
1848 the JOIN command sent by normal server. Affected file is
1849 silcd/command.c. The router now resolves the client's
1850 information from the server who sent the JOIN command if it
1851 does not know it, and processes the JOIN command only after
1854 * Changed the SilcCommandCb to take new argument; void *context2.
1855 Affected file lib/silccore/silccommand.h
1857 The second argument in the command callbacks in the server now
1858 includes the SilcServerCommandReplyContext if the command was
1859 called as pending command callback from the command reply.
1860 Otherwise it is NULL. When called as pending the status of the
1861 command reply will be checked and if it was erronous the
1862 error will be sent to the original sender of the command.
1863 This way the client always receives the error messages even
1864 though the server was actually the one who received the error
1865 when it resent the command to router, for example. Affected
1866 files silcd/command[_reply].[ch].
1868 * Fixed sending WHOWAS command's error message to client if
1869 the requested client could not be found. It was missing.
1872 * Changed the CMODE and CUMODE commands reply arguments in the
1873 protocol specification. The Channel ID is now sent in both
1874 of the commands to identify the channel. Implemented this
1875 new feature to the client and server. Affected files
1876 lib/silcclient/command_reply.c and silcd/command.c.
1878 * Made better checks for invite and ban lists in the JOIN
1879 command in server. Affected file silcd/command.c.
1881 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * The server now performs the incoming host IP/DNS lookup
1884 using the silc_socket_host_lookup and thus does not block
1885 the server anymore. Affected file silcd/server.c.
1887 * Completed the multi-thread support for SILC Scheduler in
1888 the lib/silcutil/silcschedule.c.
1890 * Fixed the configure.in.pre to detect the pthread correctly
1893 * Fixed a deadlock in silc_task_queue_wakeup in the file
1894 lib/silcutil/silctask.c.
1896 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Added new function silc_schedule_wakeup that is used in
1899 multi-threaded environment to wakeup the main thread's
1900 schduler. It needs to be used when a thread adds a new task
1901 or removes a task from task queues. After waking up, the
1902 scheduler will detect the task queue changes. If threads
1903 support is not compiled in this function has no effect.
1904 Implemented the wakeup mechanism to both Unix and WIN32
1905 systems. Affected files are lib/silcutil/silcschedule.[ch],
1906 lib/silcutil/unix/silcunixschedule.c and the
1907 lib/silcutil/win32/silcwin32schedule.c.
1909 * Added new function silc_task_queue_wakeup to wakeup the
1910 scheduler by the specified task queue. Affected file
1911 lib/silcutil/silctask.[ch].
1913 * The silc_socket_host_lookup_start now wakes up the scheduler
1914 after adding the timeout task. Affected file is
1915 lib/silcutil/silcsockconn.c.
1917 * The silc_socket_host_lookup is synchronous now if the threads
1918 support is not compiled in. However, the callback is still
1919 called asyncronously through the scheduler, anyway. Affected
1920 file lib/silcutil/silcsockconn.c.
1922 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Added new function silc_socket_host_lookup to perform
1925 asynchronous IP and FQDN lookups for the socket connection.
1926 Affected files lib/silcutil/silcsockconn.[ch].
1928 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1930 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1931 that may or may not compile the mutex support in.
1933 Changed the silc_mutex_alloc interface. It allocates the
1934 mutex now to the sent pointer and returns TRUE or FALSE.
1936 Affected file lib/silcutil/silcmutex.h.
1938 * Wrote the SILC Task Queue interface to support multi-threads.
1939 Affected file lib/silcutil/silctask.[ch].
1941 * Wrote the SILC Scheduler to support multi-threads. Affected
1942 file lib/silcutil/silcschedule.c.
1944 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1947 in lib/silcutil/win32/.
1949 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Defined SILC Mutex API and SILC Thread API and implemented
1952 them for Unix. Affected files are
1953 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1954 lib/silcutil/unix/silcunixmutex.c and
1955 lib/silcutil/unix/silcunixthread.c.
1957 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Fixed the silc_server_remove_clients_by_server's channel
1960 key re-generation. The hash table handling was incorrect
1961 and would not work with many channels. Affected file is
1964 * Fixed some memory leaks around the server code.
1966 * Rewrote the silc_server_get_users_on_channel to support IPv6
1967 based Client ID's. Affected file silcd/server.c.
1969 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1970 specification. However, a separate document must be written
1971 to define the detailed signing procedure and the payload
1972 associated with the flag. Defined the flag to the
1973 lib/silccore/silcchannel.h as well.
1975 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Changed the dynamic tables to static size tables in the
1978 lib/silccrypt/silchmac.c.
1980 * Removed GCC dependencies from the code. A patch by cras.
1982 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Do not show the error "Error receiving packet bla bla"
1985 in server if it really was not an error (-2 means that reading
1986 is pending). Affected file silcd/server.c.
1988 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Fixed a possible crash in silc_server_remove_clients_by_server
1991 in silcd/server.c. Fixed there also some memory leaks.
1993 * Fixed the silc_idlist_replace_client_id. It could replace
1994 wrong key in the hash table. Affected file silcd/idlist.c.
1996 * Do not check whether there are global users on the channel
1997 if the channel->global_users is FALSE. Affected functions
1998 silc_server_remove_from_one_channel and
1999 silc_server_remove_from_channels in silcd/server.c. Also,
2000 do not check if the removed client is local as we can be
2001 sure that global client was not removed from the channel
2002 and checking for global users is not needed.
2004 * The silc_server_remove_clients_by_server now re-generates
2005 the channel keys correctly for those channels that had
2006 clients removed from them. Affected file silcd/server.c.
2008 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Found the reason of random crashes in the server. We weren't
2011 ignoring the SIGPIPE signal (which can be sent in write())
2012 and it crashed the server. Affected file silcd/silcd.c.
2014 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Assure that sock->user_data is not NULL in the function
2017 silc_server_packet_send in silcd/packet_send.c.
2019 * Disconnect the remote connection if it could not be added
2020 to any ID lists in the server. The affected file is
2023 * Check in silc_server_packet_send[_real/dest] that the
2024 socket is not disconnecting and ignore the data if it is.
2025 Affected file silcd/packet_send.c.
2027 * Define inline to __inline on native WIN32 compilation.
2028 Affected file includes/silcwin32.h.
2030 * Added some explicit type casts for inline code since MSVC
2031 require them. Affected files lib/silcutil/silcbuffer.h,
2032 lib/trq/silcdlist.h and lib/trq/silclist.h.
2034 * Print warning in log files from now on if the packet
2035 decryption fails. Affected file silcd/server.c.
2037 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Changed the `say' client operation's interface to accept
2040 new `type' argument to indicate the type of the message sent
2041 by the library. The application may filter the library's
2042 messages according the type. The affected file is the
2043 lib/silcclient/silcapi.h.
2045 * Added two new functions to lib/silcclient/silcapi.h:
2046 silc_client_del_client and silc_client_del_client_by_id.
2047 Affected file lib/silcclient/idlist.c.
2049 * Moved the clientincludes.h from includes/ to silc/ and
2050 serverincludes.h from includes/ to silcd/.
2052 * The modes for the CMODE and CUMODE are now passed as
2053 uint32 for application with COMMAND_REPLY. The affected
2054 file is lib/silcclient/command_reply.c.
2056 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2058 * /WHOIS without arguments shows client's own information.
2059 Affected file lib/silcclient/command.c.
2061 * Changed PING to not accept any arguments. The specs
2062 says that client can ping only the connected server so
2063 requiring an argument is not needed. Affected file is
2064 lib/silcclient/command.c.
2066 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Fixed a fatal bug in private message sending and reception
2069 encryption and decryption when using private message keys.
2070 The implementation was incorrect and did not follow the
2071 specification. It causd that some of the message were
2072 lost since it did not use the sending and receiving keys
2073 as the protocol suggests. This has been fixed and will cause
2074 incompatibilities with older clients when sending private
2075 message encrypted with private message keys. Affected files
2076 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2077 and various other in Irssi SILC Client.
2079 Added `responder' boolean argument to the functions
2080 silc_client_add_private_message_key[_ske] to indicate when
2081 the key is added as responder or initiator of the key
2084 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2086 * Removed the silc_ske_check_version function and created
2087 a SilcSKECheckVersion callback. Added also a function
2088 silc_ske_set_callbacks that is now used to set all SKE
2089 callbacks. The callback functions are not given to
2090 the SKE functions anymore, but this function is used to
2093 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2095 * Added `silc_version' argument to the silc_client_alloc
2096 to define the version of the application for the library.
2097 The library will use the version string to compare it
2098 against the remote host's (usually a server) version
2099 string. Affected file lib/silcclient/silcapi.h
2101 * Added the KE protocol context to Key Agreement context
2102 in client library so that we can abort the SKE if it
2103 is in process when we get timeout. Affected file is
2104 lib/silcclient/client_keyagr.c.
2106 * Do not resolve the client ID forever if it returns in the
2107 first time that such client does not exist. This was done
2108 for example with private message. Affected file is
2109 lib/silcclient/client_prvmsg.c.
2111 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2113 * Do not add regex.h for WIN32. The affected file
2114 includes/silcincludes.h.
2116 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2117 not work yet 100%. It generates the DLL's automatically
2118 when compiling with --with-win32 under cygwin.
2120 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * lib/contrib/regex.c is not compiled on WIN32.
2124 * Added silc_net_get_socket_opt function to the
2125 lib/silcutil/silcnet.h.
2127 * Added includes/silcwin32.h for WIN32 specific includes
2130 * Do not use ptime structure or any of the posix process
2131 functions on WIN32 in lib/silccrypt/silrng.c.
2133 * Added silc_gettimeofday to provide generic function
2134 for struct timeval on all platforms. Added the function
2135 to lib/silcutil/silcutil.h.
2137 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2140 library as they clearly belong there. As a plus side we
2141 can make the actual socket connection routines platform
2144 Added also new generic function silc_socket_read and
2145 silc_socket_write (that used to be silc_packet_[read/write].
2146 The implementation of these are platform specific.
2148 * Added WIN32 specific routines of silc_socket_[read/write]
2149 to lib/silcutil/win32/silcwin32sockconn.c.
2151 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Added preliminary support for native WIN32 compilation under
2154 cygwin (using the -mno-cygwin option for GCC) to the
2155 ./configure.in.pre. The --with-win32 now prepares the
2156 compilation for native WIN32.
2158 * Rewrote the SILC Scheduler interface in the file
2159 lib/silcutil/silcschedule.h. The scheduler is now context
2160 based and does not have anymore any global static scheduler.
2161 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2162 and created lib/silcutil/win32 directory for WIN32 based
2165 * Added Unix specific network routines to the
2166 lib/silcutil/unix/silcunixnet.c and the old
2167 lib/silcutil/silcnet.c includes now only generic routines.
2169 Added WIN32 specific network routines to the
2170 lib/silcutil/win32/silcwin32net.c.
2172 * Added Unix specific utility functions from the
2173 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2175 * Added WIN32 SILC Scheduler to the file
2176 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2179 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Do not handle JOIN notify in the server if the target client
2182 is not registered (idata->registered == FALSE). The affected
2183 file is silcd/packet_receive.c.
2185 * Update the nickrec->founder in event_cumode in the Irssi SILC
2186 client. Affected file irssi/src/silc/core/silc-channels.c.
2188 * Fixed the CUMODE_CHANGE notify handling in the server when
2189 server and router are announcing their clients on channels.
2190 Now the mode changes are saved and notified correctly. The
2191 affected file is /silcd/packet_receive.c.
2193 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2194 They really did not replace the cache entry in the ID Cache.
2195 Now they do that. Affected file silcd/idlist.c.
2197 * Fixed the KICK notify handling in the Irssi SILC client to
2198 update the channel records so that the kicked client does not
2199 appear to be on the channel. The affected file is
2200 irssi/src/silc/core/silc-channels.c.
2202 * Always update the conn->current_channel when executing command
2203 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2205 * Fixed the KILL notify handling in Irssi SILC client to remove
2206 the killed client on all channels.
2208 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Fixed the silc_parse_command_line to remove extra spaces
2211 from the start and end of the arguments. Affected file is
2212 lib/silcutil/silcutil.c.
2214 * Cancel and free any active protocol in the function
2215 silc_server_close_connection. Affected file silcd/server.c.
2217 * Cancel and free any active protocol in the function
2218 silc_client_close_connction. Affected file is
2219 lib/silcclient/client.c.
2221 * Do not execute the KILL command for clients that are in
2222 history (ie. they are not in the network). Affected file is
2225 * Fixed KILL notify handling, client does not crash anymore.
2226 Affected file irssi/src/silc/core/silc-channels.c.
2228 * Reduced the default packet buffer size from 2048 to 1024 in
2229 lib/silccore/silcpacket.c.
2231 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2232 counter to the SKE context that is incresed when the SKE library
2233 performs async operation outside the library. If the outside
2234 process frees the SKE context and FREED status will be set
2235 and the library will detect after the sync operation that the
2236 libary is freed. The affected files are
2237 lib/silcske/silcske[_status].[ch].
2239 * Resolve the client entry information in the function
2240 silc_client_channel_message to assure that NULL pointer is not
2241 passed as client entry to the application. */
2243 * Fixed the task timeout calculation to assure that there is
2244 never negative timeouts. The affected file is
2245 lib/silcutil/silcschedule.c.
2247 * Fixed the channel user mode notification sending in server.
2248 It was sent point-to-point to the router (or to server by router)
2249 but it needs to be destined to a channel. The routines now
2250 supports sending the channel user mode notifys to the channels
2251 when announcing clients and channels. Affected files are
2252 silcd/server.c and silcd/packet_receive.c.
2254 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2255 It did not actually replace the old channel entry in the cache.
2256 Affected file lib/silcclient/client_notify.c.
2258 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Fixed a possible crash in silc_packet_send_prepare. It now
2261 assures always that there is enough space in the buffer and
2262 at the tail area of the buffer (for MAC).
2264 Fixed the inbound buffer reallocation in silc_packet_read.
2265 It was old code and did not handle the reallocation correctly.
2268 The affected file is lib/silccore/silcpacket.c.
2270 * Fixed buffer overflow in silc_parse_nickname in the file
2271 lib/silcutil/silcutil.c.
2273 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * make install generates new server keys only if there is not
2278 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2280 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2281 Added check that if the NOREPLY is set then we will not send
2282 the away message. This avoids infinite loop of away messages
2283 if both clients are away. The affected file is
2284 lib/silcclient/client_prvmsg.c.
2286 * Fixed client crash if /NICK was given without arguments.
2287 Affected file lib/silcclient/command.c.
2289 * Server does not send the invite list in INVITE command back
2290 to the client if the list was not altered. Added this notion
2291 to the protocol spec as well. Affected file silcd/command.c.
2293 Fixed possible crash in INVITE command by checking the
2294 value of silc_server_get_client_route command.
2296 * Fixed the INVITE notify type handling. The arguments are now
2297 taken in correct order and client does not crash. The affected
2298 file is irssi/src/silc/core/silc-channels.c.
2300 Removed the "Inviting xxx to channel" message from the
2301 client library away and let the application handle it.
2302 Affected file lib/silcclient/command.c. Added that message
2303 to Irssi SILC client's message formats.
2305 * Fixed CMODE command crash in client. It now checks the
2306 amount of arguments correctly and does not crash. The affected
2307 file is lib/silcclient/command.c.
2309 * Do not create new channel automatically in silc_channels_join
2310 but check whether the channel by that name already exists.
2311 Affected file irssi/silc/core/silc-channels.c.
2313 * Do not send the SERVER_SIGNOFF to router if the disconnected
2314 entity was the router. Affected file silcd/server.c.
2316 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2317 SILC client as it was missing from there.
2319 Added the handling of the KICK notify to the Irssi SILC client
2320 as it was missing. Added "you have been kicked" message to
2321 Irssi SILC client's message modules formats.
2323 Added the handing of the KILL notify to the Irssi SILC client
2324 as it was missing. Added the kill message module formats
2327 The affected file is irssi/src/silc/core/silc-channels.c.
2329 * The router did not save the channel mode the server announced.
2330 Affected file silcd/packet_receive.c.
2332 * Fixed a possible crash in INFO command in server. If the
2333 server did not provide the server info it crashed. Affected
2334 file silcd/command.c.
2336 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Fixed the GETKEY command in the server to check also the
2339 global list. Otherwise the GETKEY would not work correctly
2340 in normal SILC server. Affected file silcd/command.c.
2342 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Fixed GETKEY crash, it crashed if the command did not succseed.
2346 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2349 is now real and not just an macro interface to GMP.
2351 Removed the entire GMP from the source tree and imported new
2352 NSS MPI library instead. Reason for removing GMP is that it is
2353 extremely large and compiles extremely slow. The NSS MPI
2354 is only a few files and compiles in less than 10 seconds.
2355 The speed is also about the same as GMP. The MPI is imported
2356 to lib/silcmath/mpi.
2358 If the system has GMP installed we will still use the GMP.
2359 If it is not then the NSS MPI will be compiled.
2361 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2363 * Merged a long nickname (127 characters long) crash bugfix from
2364 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2366 * Merged a freed memory reference bugfix from Irssi CVS tree.
2367 Affected file irssi/src/core/commands.c.
2369 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Added the server's public key sving and verification to the
2372 server when performing the SKE. This was missing and the
2373 remote server's (or router's) public key was accepted without
2374 checking whether we have it previously or trust it at all.
2375 Affected file silcd/protocol.c.
2377 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Check in the silc_server_timeout_remote if protocol is active
2380 and make sure that the protocol's final callback is called so
2381 that all memory if freed. Affected file silcd/server.c.
2383 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2385 * silc_server_whois_send_reply crashed the server if the nickname
2386 was 127 characters long. Affected file silcd/command.c.
2388 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Added sanity check to the silc_server_new_client. If the hostname
2391 is provided inside username then check that the provided hostname
2392 really is the same as the resolved one. If the hostname was not
2393 resolved then check it from the public key. Affected file is
2394 silcd/packet_receive.c.
2396 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2397 if the server disconnected us and the connection is not valid
2398 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2400 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2401 the library to the lib/silcutil/silcutil.[ch].
2403 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Close log file after open. Affected file
2406 lib/silcutil/silclog.c.
2408 * Check whether sock == NULL in silc_client_send_packet and return
2409 if it is. Affected file lib/silcclient/silcclient.c.
2411 * Check rec->entry == NULL in the Irssi SILC Client before
2412 sending the channel message. Affecte file is
2413 irssi/src/silc/core/silc-servers.c.
2415 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Merged a splitted window bugfix from Irssi CVS tree. The
2418 affected file is irssi/src/fe-text/textbuffer-view.c.
2420 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2421 It did not print nickname.
2423 * Improved the distributions system a bit.
2425 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2427 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2428 irssi/src/fe-text/gui-window.c.
2430 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2431 to in-active server. The affected file is
2432 irssi/src/silc/core/client_ops.c.
2434 * Resolve the client in USERS command reply if the entry does
2435 not have username resolved. The affected file is
2436 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2437 command to WHOIS command to really resolve stuff. The USERS
2438 is not used any more in any critical section so WHOIS can
2439 be used even though it might be slower than IDENTIFY.
2441 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2444 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Changed the protocol API a bit more consistent in the
2447 lib/silccore/silcprotocol.[ch].
2449 * Changed the following headers to ROBODoc format:
2451 lib/silccore/silcpayload.h
2452 lib/silccore/silcprotocol.h
2453 lib/silccore/silcsockconn.h
2455 All core library headers are now formatted.
2457 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Fixed a bug in Irssi SILC client; do not show that you are
2460 server/router operator if you really are not. Affected file is
2461 irssi/src/silc/core/client_ops.c.
2463 * Renamed silc_command_free_payload to silc_command_payload_free.
2464 Affected file lib/silccore/silccommand.h
2466 * Added silcmath.h to include the prototoypes of various routines
2467 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2470 * Changed the following headers to ROBODoc format:
2472 lib/silccore/silcchannel.h
2473 lib/silccore/silccommand.h
2474 lib/silccore/silcid.h
2475 lib/silccore/silcidcache.h
2476 lib/silccore/silcmode.h
2477 lib/silccore/silcnotify.h
2478 lib/silccore/silcpacket.h
2479 lib/silcmath/silcmath.h
2481 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Added checking to the server code not to start the server if
2484 ciphers and stuff are not configured properly. Affected files
2485 silcd/serverconfig.[h] and silcd/server.c.
2487 * Changed the layout of the header files of the public interfaces
2488 in the SILC libraries. The new layout supports ROBODoc
2489 documentation tool (and some others) so that it is easy to create
2490 a library reference manual. All the other headers and source
2491 code must still follow the CodingStyle document. Also source
2492 code must not include these ROBODoc stuffs, only the headers.
2493 Furthermore, all public interface headers must now be named
2494 by using `silc' prefix, example: silcapi.h, silccipher.h.
2495 Some files were renamed due to this. All the other headers
2496 must not be used as public interfaces. I will update the
2497 CodingStyle document later. Changed following headers, so far:
2499 lib/silcclient/silcapi.h
2500 lib/silccore/silcauth.h
2501 lib/silccore/silcprivate.h
2502 lib/silccrypt/silcdh.h
2504 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Removed silc_client_packet_send_flush from the client library
2509 as it is not needed. Affected file lib/silcclient/client.[ch].
2511 * Added printing of message of unresolved authentication method
2512 to the Irssi SILC client. Added it to the module formats.
2513 Removed the same message from the client library.
2515 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added new distribution feature, DISTLABEL. Every distribution
2518 can define own preprocessor label that can be used in the
2519 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2520 file distributions, acconfig.h.pre and prepare.
2522 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Added Makefile.defines_int to include the actual definitions
2525 for Makefile.defines.in. Tested the new distribution system,
2526 created distributions and tested installation.
2528 * Added AWAY message printing to the Irssi SILC client. Added
2529 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2531 * Added SCONNECT command to call the SILC's CONNECT command.
2532 Cannot use CONNECT directly since Irssi uses that internally.
2533 Affected file irssi/src/silc/core/silc-servers.c.
2535 Added ACTION local command. It is same as ME command but takes
2536 the channel as mandatory argument.
2538 Rewrote some of the Irssi's help files to suite for SILC
2541 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2543 * Added Makefile.defines[.in] that should for now on be included
2544 in all Makefile.am file in the source tree. That file includes
2545 all common compilation definitions for SILC source tree.
2547 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Minor changes to the ./prepare script to change the package
2550 name according the distribution name to the configure.in.
2552 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2554 * Created new distribution system. Added file `distributions'
2555 that defines all the distributions that can be created out of
2556 the SILC source tree. The ./prepare script now reads that
2557 file to determine how to prepare the distributions. The
2558 first argument to the ./prepare is the name of the distribution
2559 and second is the version of the distribution. If given
2560 without arguments it creates the default (toolkit) distribution
2561 with the default version (defined in ./prepare).
2563 All Makefile.am files that are subject to the distributions
2564 are now named as Makefile.am.pre. These are ./Makefile.am
2565 and lib/Makefile.am. Others may be changed later.
2567 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Added invite list, ban list, some key management and connection
2570 error message printing to module formats in the Irssi SILC client.
2572 * Added new silc_client_set_away_message to set the away message
2573 that is back to the person who sent private message. The
2574 affected file lib/silcclient/silcapi.h and the
2575 lib/silcclient/client_prvmsg.c.
2577 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Fixed the private message sending in the Irssi SILC client,
2580 added local command KEY to the Irssi SILC client.
2582 Added key management and key agreement message formats to the
2583 irssi/src/fe-common/silc/module-formats.[ch].
2585 Added USERS (alias WHO) printing, server/router operator
2586 indication and LIST command printing to the module formats.
2588 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2590 * Fixed channel joining notify handling, cumode notify handling
2591 from Irssi SILC client.
2593 * Added SILC specific module-formats to the Irssi SILC client so
2594 that SILC specific message hilighting, colors etc is possible.
2595 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2597 Added channel mode, channel user mode, actions, notices,
2598 whois and whowas printing to the the module-formats.c.
2600 * Fixed a bug in channel deletion in the server. The channel
2601 is not left to the cache even if the channel founder auth mode
2602 is set when there are no users anymore on the channel. Affected
2603 file silcd/server.c.
2605 * The silc_net_localhost now resolves the entire hostname including
2606 the domain name. Affected file lib/silcutil/silcnet.c.
2608 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Changed the ask_passphrase client operation to be ascynchronous.
2611 It has now a completion callback and a context that the
2612 application must call after it has got the passphrase from
2613 the user. Affected files lib/silcclient/silcapi.h,
2614 lib/silcclient/protocol.c, lib/silcclient/command.c and
2617 Added SilcAskPassphrase callback that the application calls
2618 to deliver the passphrase to the library.
2620 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2621 The public key verification and especially a certificate
2622 verification is asynchronous procedure.
2624 Added new SILC_SKE_STATUS_PENDING status to indicate the
2625 request is pending and a callback will be called to finalize
2628 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2629 indicate that remote end did not send its public key (or
2630 certificate), even though we require it. Added check for this
2631 condition in the SKE. This was a security bug, now fixed.
2633 Defined new SilcSKEVerifyCbCompletion callback that is called
2634 when the verification process is completed.
2636 The affected files lib/silcske/silcske_status.h and
2637 lib/silcske/silcske.[ch].
2639 * Changed the verify_public_key client operation to be async
2640 as well. Defined SilcVerifyPublicKey callback that is used to
2641 indicate the success of the public key verification process.
2643 Changed the server and client to use the new async client
2646 * Changed the Irssi SILC client's internal scheduler to be called
2647 twice as many times as it used to be. As a result the client
2648 should be a bit faster now. Affected file is
2649 irssi/src/silc/core/silc-core.c.
2651 * Added support to Irssi SILC client of asynchronous public key
2652 verification and passphrase inquiry. Affected file is
2653 irssi/src/silc/core/silc-core.c.
2655 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Do not say "You have left channel %s" in client library.
2658 Moved it to the application. Affected files are
2659 lib/silcclient/command.c and silc/client_ops.c.
2661 * Fixed silc_client_get_clients. Command context was not
2662 duplicated and was freed memory in the callback. Affected
2663 file lib/silcclient/idlist.c.
2665 * Do not say "you are now talking..." on JOIN command in the
2666 client library. The appliation must handle it.
2668 * Do not say ".. changed topic to" in command reply in the
2669 client libary. The application must handle it.
2671 * Fixed TOPIC command sending in the client library.
2673 * Fixed a memory leak in silc_client_command_free in the file
2674 lib/silcclient/command.c.
2676 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Imported a modified version of Irssi client to the source tree.
2679 The Irssi will be used to create a new client called
2680 Irssi SILC. Imported to irssi/.
2682 Added silc_core_init_finish function to the Irssi. Affected
2683 file irssi/configure.in.
2685 A lot changes in the Makefile.ams around the irssi tree.
2687 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * Do not rehash if the new size is same as the old size of the
2690 hash table, in the silc_hash_table_rehash*. The affected file
2691 lib/silcutil/silchashtable.c.
2693 * Replaced hash_table_del_by_context calls from the server
2694 (when channel->user_list and client->channels) to the
2695 hash_table_del as it is sufficient and faster.
2697 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Added silc_hash_table_list, silc_hash_table_get and the
2700 SilcHashTableList structure to provide an alternative way to
2701 traverse the hash table. The affected files are
2702 lib/silcutil/silchashtable.[ch].
2704 * Changed the server's idlist routines to use the hash table
2705 routines to optimize the code.
2707 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Replaced the client entry's `channel' list and channel entry's
2710 `user_list' list to hash tables for optimized lookup. Changed
2711 the code to use the hash table interface around the code.
2712 Affected file lib/silcd/idlist.[ch].
2714 * Added `auto_rehash' boolean argument to the function
2715 silc_hash_table_alloc to indicate whether the hash table should
2716 auto-rehash when it thinks is appropriate time. It will
2717 increase the hash table size if the there is twice as much
2718 entries in the table than the size of the table, and will
2719 decrease the size if there are twice as less entries than
2720 the size of the table.
2722 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2726 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * silc_idcache_purge_by_context deletes the entry now by context
2729 as it is supposed to do. Affected file lib/silccore/idcache.c.
2731 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2732 client is not anymore valid (WHOWAS givens the info) and not
2733 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2735 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Removed the `data' and `data_len' arguments from the ID Cache
2738 interfaces and added `name' argument. ID Cache does not handle
2739 anymore the binary data only a names associated with given ID.
2741 * When hashing a Client ID with silc_hash_id the entire ID is
2742 not hashed anymore, instead only the hash of the Client ID is
2743 hashed. This way we can access the Client ID from the cache
2744 with Client ID but with the hash of the ID (which is a hash of
2745 the nickname) as well without any difference in performance.
2747 Added also silc_idcache_find_by_id_one_ext to do one on one
2748 searching when we have the actual ID. Added also function
2749 silc_hash_client_id_compare. The affected files are
2750 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2752 * When hashing the name associated with a ID it is always done
2753 in lowercase. This way we can access the cache without worrying
2754 about case-sensitivity, even though, for example nicknames are
2757 * Fixed a bug in server with channel message sending. It put
2758 wrong ID type as destination ID. The affected file
2759 silcd/packet_send.c.
2761 * silc_idcache_del_by_context now deletes from all hash tables
2762 by context. Affected file lib/silccore/idcache.c.
2764 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Changed the client library to use the new ID Cache interface.
2767 Changes around the source tree.
2769 * Added silc_hash_table_rehash_ext to rehash with specific
2770 hash function. Affected file lib/silcutil/silchashtable.[ch].
2772 * Added silc_hash_string_compare to compare two strings in the
2773 hash table. Affected file lib/silcutil/silcutil.[ch].
2775 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Added new function silc_idcache_del_by_context into the
2778 lib/silccore/idcache.[ch].
2780 * Changed the server's ID list routines to use the new ID Cache
2781 interface. Changes around the source tree.
2783 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2785 * Added silc_hash_table_del[_by_context]_ext functions in to the
2786 lib/silcutil/silchashtable.[ch].
2788 Removed silc_hash_table_find_all* routines and added new
2789 silc_hash_table_find_foreach to replace them.
2791 Added silc_hash_table_replace_ext function as extended
2792 replacing function. Separated the simple hash table interface
2793 from the extended hash table interface in the file
2794 lib/silcutil/silchashtable.h.
2796 * Fixed minor bugs and changed it to use some of the new
2797 hash table functions in lib/silccore/idcache.c
2799 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Added new function silc_hash_table_find_all to return all keys
2802 in the hash table by the specified key. As the hash table is
2803 collision resistant it also makes it possible to have several
2804 duplicate keys in the hash table. This function may be used to
2805 find all of the keys from the hash.
2807 Added user_context arguments to the SilcHashFunction,
2808 SilcHashCompare and SilcHashDestructor to deliver user specified
2811 Added new fuctions silc_hash_table_find[_all]_ext to do
2812 extended lookup with specified hash and compare functions and
2813 specified user contexts.
2815 Added new function silc_hash_table_add_ext to add the key
2816 with specified hash function and user context.
2818 Added new function silc_hash_table_foreach to traverse all
2819 entrys in the hash table. Added SilcHashForeach callback
2822 Added new function silc_hash_table_del_by_context to delete
2823 the entry only if the context associated with the key matches.
2825 Affected files are lib/silcutil/silchashtable.[ch].
2827 * Removed silc_hash_[server/client/channel]_id and added just
2828 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2829 silc_hash_id_compare to compare two ID's using as the hash table
2830 comparison function. Added also silc_hash_data to hash
2831 binary data and silc_hash_data_compare to compare it.
2833 * Removed silc_idlist_find_client_by_hash as it is not needed
2834 anymore. Affected file silcd/idlist.[ch].
2836 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2837 to use internally the SilcHashTable. The new ID Cache is a lot
2838 faster than the old one. Some of the ID Cache interface was also
2839 rewritten and obsolete and stupid functions were removed.
2841 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Added entry_count field to the SilcHashTable to keep the number
2844 of the entries in the table. Implemented the function
2845 silc_hash_table_rehash. Added new function
2846 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2848 Fixed a minor bug in silc_hash_table_free.
2850 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2851 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2852 into the lib/silcutil/silcutil.[ch].
2854 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Implemented a collision resistant hash table into the
2857 lib/silcutil/silchashtable[ch]. See the header and the source
2858 for the SilcHashTable API.
2860 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Merged dotconf version 1.0.2 into lib/dotconf.
2864 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Do not compile anything in lib/silcsim/* if the SIM support
2867 is not enabled. The tree should now compile without problems
2870 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Compiled the SILC under cygwin. Compiled and tested briefly
2873 without problems. More tests needed. The SIMs didn't compile
2876 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2878 * Fixed possible crash in silc_get_username in the
2879 lib/silcutil/silcutil.c.
2881 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Fixed a va_arg in silc/client_ops.c.
2885 * Oops, RC5 routines were named AES and caused some problems
2886 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2888 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Added new SilcIDIP structure into the lib/silccore/id.h and
2891 replaced the old `ip' fields from all SILC ID's to that type.
2892 This is a step towards IPv6 support.
2894 The silc_id_get_len takes now the ID as an extra argument.
2895 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2896 both IPv4 and IPv6 based ID's.
2898 The affected files are lib/silccore/id.[ch] and other files
2899 around the tree using these routines.
2901 * Removed the ID length arguments in server from various
2902 silc_server_send_notify_* routines -> they are not needed
2905 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Fixed memory leak in silc_encode_pem_file in the file
2908 lib/silcutil/silcutil.c.
2910 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * Check minor version as well in the SKE. Affected files are
2913 silcd/protocol.c and lib/silcclient/protocol.c.
2915 * Added --identifier option to the server so that an identifier
2916 can be when creating the public key for the server. Affected
2917 file is silcd/silcd.c.
2919 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2920 lib/silccrypt/silcpkcs.c.
2922 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Register default ciphers and stuff when using -C option with
2925 the server. Affected file sildc/silcd.c.
2927 * Put back the servers public key filename format, it is better
2928 than the new one. For now, the client keys are saved with the
2929 new filename format. The affected file silc/client_ops.c.
2931 * Implemented the Cipher API for the rest of the ciphers that
2932 did not implement it or implemented it the wrong way.
2934 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Register default ciphers and stuff when using the -S option
2937 in the client. Affected file silc/silc.c. Same also when
2938 creating new key pair with -C option.
2940 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2942 * Fixed the silc_verify_public_key client operation function to
2943 save the public keys differently. The fingerprint is now
2944 used as filename and not the hostname. This way also the
2945 client keys are saved uniquely and not with hostnames. The
2946 affected file is silc/client_ops.c.
2948 * Trimmed the silc_hash_fingerprint function to remove extra
2949 whitespaces from the end of the fingerprint. The affected
2950 file is lib/silccrypt/silchash.c.
2954 * Added silc_cipher_register_default function to register all
2955 default ciphers. It can be used when configuration files
2956 does not exist and the application does not want any specific
2957 ciphers in any specific order.
2959 The SilcDList is now used as silc_cipher_list dynamically
2960 allocated cipher list. Removed the static list all together
2961 and now all ciphers must be allocated to the dynamic list.
2962 The silc_cipher_alloc routine was changed to check only the
2965 All silc_cipher_* routines that used to return int returns
2968 The affected files lib/silccrypt/silccrypt.[ch].
2970 * The same thing was done to silc_hash_* as for silc_cipher_*
2971 routines. Affected files lib/silccrypt/silchash.[ch].
2973 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2974 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2975 Added also silc_pkcs_[un]register[_default] functions.
2976 Removed the data_context from the PKCS API.
2978 * Added silc_hmac_register_default function to register default
2979 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2980 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2981 to unregister all hmacs at once.
2983 * Register the default ciphers, hash functions, PKCSs and HMACs
2984 if client's configuration file does not exist. The affected
2987 * The client did not load the hash functions from the SIM
2988 modules at all. Added support for this. Affected file is
2989 silc/clientconfig.c.
2991 * When decoding public key with silc_pkcs_public_key_decode, check
2992 the supported algorithm only if PKCS are registered. Affected
2993 file lib/silccrypt/silcpkcs.c. The same was done with the
2994 silc_pkcs_private_key_decode.
2996 * Fixed the SILC List routines to keep the list always in order.
2997 It used to change the list's order when traversing the list but
2998 not it preserves the order. Affected file lib/trq/silclist.h.
3000 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Added the client library to use the SilcSocketConnection's
3003 reference counter (by silc_socket_dup) to prevent the bug that
3004 the socket object may be freed underneath async operation.
3006 * The name resolv library checking fixes in the configure.in.pre.
3009 * Created new version of the protocol drafts for future
3010 development. The -03 drafts are the ones that will be changed
3011 in the trunk now and the -02 will remain as they are.
3013 * Send list of CUMODE notifys to the router when announcing
3014 the channel users to the router. Affected file silcd/server.c.
3015 If the router receiving channel founder CUMODE for a channel
3016 that already has channel founder it will send CUMODE notify
3017 to the sender to remove the channel founder rights from the
3018 announced client. Affected file silcd/packet_receive.c.
3020 * The CUMODE notify may now use Server ID as well as the entity
3021 who changes the mode. Updated protocool specs.
3023 * Updated INSTALL and README files.
3025 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * New web pages in the http://silc.pspt.fi. The pages was
3032 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3034 * Implemented the [DenyConnectin] config section in the server.
3035 Added silc_server_config_denied_conn to check whether incoming
3036 connection is denied. Affected file silcd/serverconfig.[ch].
3038 * Do not check the ports when checking the incoming configuration
3039 data if the port is 0, meaning any. Affected file is
3040 silcd/serverconfig.c.
3042 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Fixed buffer overflow in silc_string_compare in the file
3045 lib/silcutil/silcutil.c.
3047 * Fixed double free in silc_server_command_leave in the file
3050 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Fixed the version checking in the server. Affected file is
3055 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Fixed the configuration data fetching when accepting new
3058 connections in the server. Affected file silcd/server.c.
3060 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3062 * Added `sender_entry' argument to the function
3063 silc_server_packet_relay_to_channel so that we can check
3064 whether some destination actually belongs to the same route
3065 the sender belongs (ie, we must not resend the packet to the
3066 sender). Affected file silcd/packet_send.[ch].
3068 * Added `servername' field to the SilcClientEntry in the server
3069 to hold the name of the server where client is from. Affected
3070 file is silcd/idlist.h.
3072 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * Moved the channel message encrypting in the router betwen
3075 router connections from silc_server_channel_message to the
3076 silc_server_packet_relay_to_channel since we want to check
3077 whether we have anybody channel before encrypting anything.
3078 Affected files silcd/packet_[receive/send].c.
3080 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Fixed the [AdminConnection] server config section to support
3083 multiple entries. Affected file silcd/serverconfig.c.
3085 * Added support into the server to check the validity of the
3086 incoming connection before executing any KE or authentication
3089 * The connection configuration is now saved to the KE and
3090 connection auth protocol contexts and not fetched anymore in
3091 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3093 * The local hosts listenning address and port is also resolved
3094 now when starting the server. We want to have the socket object
3095 to include the real address and port for the listener. Added
3096 new function silc_net_check_local_by_sock into the files
3097 lib/silcutil/silcnet.[ch].
3099 * Fixed a broadcast bug in server -> do not broadcast if we
3102 * Fixed a routing bug. Do not route broadcast packets ever.
3103 Broadcast packets must be processed always and not routed since
3104 they may be destined to some other host than yourself and thus
3105 would get routed without no good reason. Affected file is
3108 * Added function silc_server_config_is_primary_route to check
3109 whether primary router connection has been configured (a router
3110 configuration that we are initiating). If there is not, we
3111 will assume that there is only two routers in the SILC network
3112 and we will use the incoming router connection as our primary
3113 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3115 * Changed the order of the broadcasting. Broadcast _after_ the
3116 packet has been processed not before. Affected file is
3119 * Fixed a [ClientConnection] parsing bug. The port was never
3120 parsed correctly thus resulting to port 0. Affected file
3121 silcd/serverconfig.c.
3123 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3124 argument and did not set the broadcast packet flag. Affected
3125 file silcd/packet_send.c. Fixed same bug in the function
3126 silc_server_send_notify as well.
3128 * If we receive NEW_ID packet for our own ID in the server, ignore
3131 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Removed the nickname from the Private Message Payload.
3136 Updated the code and the protocol specs.
3138 * Updated protocol specs for submitting to the IETF.
3140 * Tweaked the Random Number Generator a bit. Affected file
3141 lib/silccrypt/silcrng.c. Exported a new function
3142 silc_rng_[global]_add_noise which can be used to add more
3145 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Do not parse packets with different timeout when protocol
3148 is active -> may cause problem with rekey. Affected file
3151 * When server receives signoff notify it must not create
3152 new channel key if the client is on any channels since the
3153 sender of the signoff notify will create it.
3155 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Added printing of error messages during SKE protocol from the
3158 failure packet sent by server during SKE. Affected file
3161 * Removed the client's failure_callback handling with timeout
3162 and handle it immediately when received.
3164 * The SKE library returned wrong type in SUCCESS and FAILURE
3165 packets. They must be 32 bit MSB not 16 bit MSB.
3167 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Ok, rewrote the logic of the re-key and now it seems to work.
3170 I tested it on high traffic with frequent re-keys without
3171 problems. Added hmac_receive (and renamed hmac to hmac_send)
3172 in SilcClientConnection in lib/silcclient/client.h and
3173 in SilcIDListData in silcd/idlist.h. Also, removed the
3174 SilcPacketParserContext's cipher and hmac fields as they are
3175 not needed anymore and actually caused some problems when
3176 the ciphers and hmac's changed underneath the packet parser.
3178 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * If re-key protocol is active then process the incoming packets
3181 synchronously since we must assure that icoming packets encrypted
3182 with the old key is processed before the new keys is set to
3183 use. This is true other packets than for REKEY packets.
3184 Affected file silcd/server.c. The same was done to client library
3185 as well, affected file lib/silcclient/client.c.
3187 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Fixed bug in client and server to accept the force send if
3190 the packet is send from silc_[server/client]_packet_process
3191 function. Otherwise the packets are never delivered, oops.
3193 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3195 * Disable force sending of packets when REKEY protocol is active.
3196 We must assure that no packet is sent directly when rekey is
3197 performed. All packets must be sent through packet queue.
3198 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3199 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3200 function is silc_[server/client]_packet_send_real to check
3203 * Replaced the SIM paths from example config files to
3204 /usr/local/modules. Also, make install creates now
3205 /usr/local/silc/logs directory to hold all the SILC server
3208 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3219 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * When MAC computation fails the silc_packet_decrypt returned 0
3222 even though it was supposed to return -1. Fixed this. The
3223 affected file is lib/silccore/silcpacket.c.
3225 * Do not replace the config files in /etc/silc (in make install)
3226 if they already exist. Affected file ./Makefile.am.
3228 * Do not send re-key packets immediately but through packet queue.
3229 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3231 * Changed silc_net_check_host_by_sock to return FALSE if the
3232 IP/DNS could not be resolved. Though, it returns the IP address
3233 now even if it could not resolve it (but returns also FALSE).
3234 Affected file lib/silcutil/silcnet.[ch].
3236 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Added silc_pkcs_decode_identifier to decode the public key's
3239 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3240 Added also silc_pkcs_free_identifier. Added also new context
3241 SilcPublicKeyIdentifier.
3243 * Added -S option to the silc client. It is used to dump the
3244 contents of the specified public key file.
3246 * Changed the PKCS api to return the public key length when
3247 setting the public key.
3249 * Fixed a fatal bug in the public and private key file loading.
3250 Affected file lib/silccrypt/silcpkcs.c.
3252 * Execute the packet parsing for client with zero (0) timeout
3253 if the protocol is active. Affected file silcd/server.c.
3255 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Made the key generation options to the silcd program. Added
3258 -C option, equivalent to client's option.
3260 * Added new [ServerKeys] config section to the server. It
3261 configures the server's public and private key.
3263 * Defined generic Public Key Payload into the protocol
3264 specification to send specific type of public keys and
3267 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3268 public key or certificate.
3270 * Implemented the GETKEY command to the server and to the
3271 client library and on user interface.
3273 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Made preliminary `make install' work.
3277 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Added SilcServerRekey context into silcd/idlist.h.
3281 * Added the PFS support as defined in the specification to the
3282 SKE protocol. Affected files lib/silcske/*.c.
3284 * Added `ske_group' field to the SilcServerRekey context to hold
3285 the number of the SKE group that is used with PFS in re-key.
3286 Affected file silcd/idlist.h.
3288 * Added PFS re-key support to the server. Affected file is
3291 * Added silc_protocol_cancel to cancel execution of the next
3292 state of the protocol. Affected file is
3293 lib/silccore/silcprotocol.[ch].
3295 * Added the re-key support with and without PFS to the client
3296 library. Re-key is performed once in an hour, by default.
3298 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3299 Added silc_client_rekey_callback and silc_client_rekey_final.
3300 Affected files are lib/silcclient/protocol.[ch] and
3301 lib/silcclient/client.[ch].
3303 * Removed the `hmac_key' and `hmac_key_len' fields from the
3304 SilcClientConnection structure; not needed. Affected file is
3305 lib/silcclient/client.h.
3309 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Do not ask whether user wants to use the negotiated private key
3312 for private messages, just use it. Affected file is
3313 silc/local_command.c.
3315 * Added `send_enc_key' and `enc_key_len' fields to the
3316 SilcIDListData structure since they are needed in the re-key
3317 phase. Affected file is silcd/idlist.[ch].
3319 * Implemented the simple re-key protocol into the server.
3320 Affected files silcd/server.c and silcd/protocol.[ch]. The
3321 re-key will be performed once in an hour, by default.
3323 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3324 Added silc_server_rekey, silc_server_rekey_callback and
3325 silc_server_rekey_final.
3327 * Removed Tunneled flag from the protocol. Updated the code
3328 and the specifications.
3330 * Adde `pfs' field to the SilcIDListData to indicate whether
3331 the PFS is to be performed in the re-key. Affected file is
3334 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3336 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3337 int64 of at least the xintXX size. If void * is less that 4
3338 bytes uint32 * will be used. Defined bool as boolean.
3340 * Changed _ALL_ unsigned long and unsigned int to uint32,
3341 unsgined short to uint16 in the source tree.
3343 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3344 not handle clients that has entry->data.registered == FALSE.
3345 They are not in the network anymore. Affected file is
3348 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Implemented the sending of the SERVER_SIGNOFF notify in the
3351 server. Affected file is silcd/server.c.
3353 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3354 Added also silc_notify_payload_encode_args into the
3355 lib/silccore/silcnotify.[ch].
3357 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3358 Affected file silcd/packet_receive.c.
3360 * Implemented the SERVER_SIGNOFF notify handling in the client
3361 library. Affected file lib/silcclient/client_notify.c. Also,
3362 implemnted the printing of the SERVER_SIGNOFF info to the
3363 application. Affected file silc/client_ops.c.
3365 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3366 if the deleting was successful. Affected file silcd/idlist.[ch].
3368 * Added support for public key authentication in the connection
3369 authentication protocol in the client library. Affected file
3370 lib/silcclient/protocol.c.
3372 * Changed the server's silc_idlist_get_clients_by_* interface
3373 to support already allocated array so that new entries may be
3374 added to pre-allocated array. Affected file silcd/idlist.[ch].
3375 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3376 and command replies.
3378 * All command reply functions in the server now calls the
3379 pending command callback even if error occured. This way the
3380 error will be delivered to the client as well. Affected files
3381 silcd/command.c and silcd/command_reply.c.
3383 * Fixed INFO command to return local server's info if no server
3384 was provided. Affected file lib/silcclient/command.c.
3386 * Removed RESTART command for good. Updated the code and the
3389 * Rewrote parts of the task system. It is a bit simpler now.
3390 Removed unsued task priorities. The affected files are
3391 lib/silcutil/silctask.[ch].
3393 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Moved the USERS printing from the library to the application.
3396 Affected files lib/silcclient/command.c and silc/client_ops.c.
3398 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Added channel key re-key support. The re-key is perfomed
3403 only by the router and is done once in an hour. Added `rekey'
3404 field to the SilcChannelEntry in the server. Affected files
3405 silcd/server.c and silcd/idlist.h.
3407 * Added silc_task_unregister_by_context into the file
3408 lib/silcutil/silctask.[ch].
3410 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Added SILC_UMODE_GONE mode to indicate when the client is not
3413 present in the SILC network. Added also support to the local
3414 command AWAY that will set this mode. Added support of showing
3415 "xxx is gone" in WHOIS command. The USERS command shows the
3416 gone status as well.
3418 * Fixed setting server and router operator privileges in the
3419 server's UMODE command. Affected file silcd/command.c.
3421 * Merged the SKE KE1 and KE2 payloads into one payload. The
3422 new KE payload is equivalent to the old KE2 payload.
3424 Cleaned up the SKE Start Payload parsing. It now uses the
3425 simple buffer unformatting to do the parsing. A lot faster
3428 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3429 to the SKE that is used to indicate whether both of the SKE
3430 parties should perform authentication. By default only the
3431 responder performs authentication. By setting this flag also
3432 the initiator must do authentication. By default it is unset
3433 since in normal SKE case, client to server connection, only
3434 the responder should do authentication. When doing SKE between
3435 two clients both should perform authentication. Updated the
3436 code and the protocol specs.
3438 * A little fix to IDENTIFY command in the server. Search the
3439 client first by hash not nickname. Affected file is
3442 * Fixed the silc_client_close_connection to support closing
3443 the client to client connections wihtout deleting too much
3444 data. Affected file lib/silcclient/client.c.
3446 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3447 are received if protocol used to be active but is not anymore
3448 the application would crash due to NULL pointer dereference.
3449 Affected files silcd/server.c and lib/silcclient/client.c.
3451 * Added `hash' field to the SilcClientConnection to include
3452 the hash function negotiated in the SKE protocol.
3454 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3455 to set the channel founder authentication data. A client can
3456 claim the founder rights later by providing the authentication
3457 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3458 This way the channel founder can regain the channel founder
3459 privileges even it is left the channel. This works only on
3460 local server and the client must be connected to the same
3461 server to be able to regain the founder rights. Updated the
3462 protocol specs accordingly.
3464 Added support to the CMODE command in the client to set the
3465 founder auth data. Read the README to see how to set it.
3467 Added support to the CUMODE command to claim the founder
3468 rights. Read the README to see how to do it.
3470 Added support for the founder authentication to the Channel
3471 Entry in the server. Affected file silcd/idlist.h.
3473 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3474 server's CMODE command. Affected file silcd/command.c.
3476 * Added the following new functions into lib/silccore/silcauth.[ch]:
3477 silc_auth_get_method and silc_auth_get_data.
3479 * The server now saves the remote hosts public key to the
3480 SilcIDListData pointer. Affected file silcd/protocol.c.
3482 * The normal server now does not remove the channel entry from
3483 the cache if the founder authentication data is set. It used
3484 to remove it if the founder was the last one on the channel on
3485 the server and left the channel. The auth data is saved and
3486 if the channel is re-joined later the old entry is used with
3487 the old auth data. Affected files silcd/command_reply.c and
3490 * Removed the `pkcs' field from the SilcIDListData structure
3491 in the server; it is not used. Affected file silcd/idlist.h.
3493 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Fixed packet processing on slow links. Partial packets were
3496 never re-processed because the incoming data buffer was cleared
3497 by the application. Application must not directly clear the
3498 sock->inbuf, the packet processing routines handle it. Fixed
3499 this in client library and in server.
3501 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Fixed the WHOIS and IDENTIFY send reply function to really
3504 check whether to send list or just one entry. Affected file
3507 * Cleaned up the LEAVE command's channel key distribution. The
3508 affected file silcd/command.c.
3510 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3511 can enforce the channel mode as well. In that case the ID
3512 includes the ID of the server. The code now enforces the
3513 mode change if the router have different mode than the server.
3515 * The notify client operation with CMODE_CHANGE notify can now
3516 return NULL client_entry pointer if the CMODE was not changed
3517 by client. Application must check for this.
3519 * Added <Server ID> argument to INFO command to support server
3520 info fetching by Server ID.
3522 * Added silc_server_announce_get_channel_users to get assembled
3523 packets of channel users of the specified channel. Affected
3524 file silcd/server.[ch].
3526 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3527 was freed underneath the ID Cache.
3529 * Re-announce clients when the server received CHANNEL_CHANGE
3530 notify from the router. Affected file silcd/packet_send.c.
3532 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3535 crashed since it did not handle the fact that there is no cipher
3536 called "3" and didn't check the error condition. Now fixed.
3538 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3539 flag. It can be used to send message requests.
3541 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Implemented the RESTART command in the client.
3545 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3546 notice type messages. Added notice printing to the user
3549 * The channel keys are not re-generated if the channel's mode
3550 is PRIVKEY, ie private key on the channel exists. Affected
3551 files silcd/server.c and silcd/command.c.
3553 * Fixed a little bug in channel message delivery when channel
3554 private keys are set in the server. Affected file is
3555 silcd/packet_send.c.
3557 * Changed the setting on channel->on_channel = TRUE from the
3558 silc_client_save_channel_key to the JOIN command reply. The
3559 key payload is not received if the private channel key is set.
3560 Affected file lib/silcclient/command_reply.c and the
3561 lib/silcclient/client_channel.c.
3563 * When the CMODE_CHANGE notify is sent and the channel private
3564 key mode is removed the channel key must be re-generated in
3565 other cells as well. Added this support for the router in the
3566 silcd/packet_receive.c.
3568 * Added new local command NOTICE to send notice message on
3569 channel. Affected file silc/local_command.[ch].
3571 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Added new local command ME to the client. It is used to send
3574 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3575 some action. Affected file silc/local_command.[ch].
3577 * Changed channel_message and private_message client operations
3578 to deliver the message flags to the application. Added also
3579 the `flags' arguments to the silc_client_send_channel_message
3580 and silc_client_send_private_message functions. Affected file
3583 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Redefined the Private Message Payload to support private message
3586 keys and to support the new private message flags. Updated
3587 the protocol specs. Flags makes it possible to have for example
3588 CTCP style messages.
3590 * Added new type SilcPrivateMessagePayload and defined an API
3591 for it in the lib/silcclient/silcprivate.[ch].
3593 * Tested private message private keys successfully. Tested the
3594 private message key set, unset and list commands with the new
3597 * Redefined the Channel Message Payload to include the channel
3598 message flags (equal with private message flags) to support
3599 for example CTCP style messages.
3601 * Defined some of the message (for channel and private message)
3602 flags. Updated the protocol specs and added the flags to the
3603 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3605 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added SilcKeyAgreementStatus type to the key agreement routines
3608 to indicate the current status and error if one occured.
3609 The status types are defined in the lib/silcclient/silcapi.h.
3611 * Added new local command KEY that is used to set and unset private
3612 keys for channels, set and unset private keys for private messages
3613 with remote clients and to send key agreement requests and
3614 negotiate the key agreement protocol with remote client. The
3615 key agreement is supported only to negotiate private message keys,
3616 it currently cannot be used to negotiate private keys for channels,
3617 as it is not convenient for that purpose.
3619 * Fixed a minor pending callback setting bug in the function
3620 silc_client_get_client_by_id_resolve, now the function works.
3621 Affected file lib/silcclient/idlist.c.
3623 * Added function silc_net_get_local_port to get local bound
3624 port by socket. Added to lib/silcutil/silcnet.[ch].
3626 * Added `sockets' and `sockets_count' fields to the SilcClient
3627 object. They hold the sockets of the listenning sockets in
3628 the client. Listenning sockets may be for example the key
3629 agreement server. Affected file lib/silcclient/client.[ch].
3630 Added functions the silc_client_add_socket and the
3631 silc_client_del_socket. They are exported to the application
3634 * Added ~./silc/clientkeys to support other client's public keys.
3636 * Renamed verify_server_key client operation to verify_public_key
3637 and added one argument to indicate the type of the connection
3638 (server, client etc.).
3640 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Added silc_server_connection_auth_request to handle the
3643 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3644 silcd/packet_receive.[ch].
3646 * Added silc_server_send_connection_auth_request into the
3647 silcd/packet_send.c to send the connection auth request packet.
3649 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3652 * Fixed the public key authentication in responder side in the
3653 server. The `auth_data' pointer includes the SilcPublicKey
3654 not the path to the public key. Affected file silcd/protocol.c.
3656 * Implemented the public key authentication in the initiator side
3657 in the server. Affected file silcd/protocol.c.
3659 * Removed the [RedirectClient] config section from the server
3660 configuration. Is not needed and I don't want to implement it.
3662 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Cleaned up the CMODE command in the server. It now works
3665 correctly and supports all the modes defined in the protocol.
3666 Affected file is silcd/command.c.
3668 * Added `hmac_name' field to the SilcChannelEntry in the server
3669 to hold the default HMAC of the channel. It can be set when
3670 creating the channel (with JOIN command). Affected files
3673 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3674 type to indicate the change of the current cipher and hmac
3675 on the channel. Client can safely ignore the <cipher> argument
3676 (if it chooses to do so) since the CHANNEL_KEY packet will
3677 force the channel key change anyway. The <hmac> argument is
3678 important since the client is responsible of setting the new
3679 HMAC and the hmac key into use.
3681 * Fixed the CMODE command in the client library as well.
3683 * Tested CMODE command in router environment successfully.
3685 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Show the version of the remote client (or server) when connecting
3688 to the server. It is logged to the log file. Affected file
3689 is silcd/protocol.c.
3691 * Fixed the KILLED notify handling in the client library. The
3692 client must be removed from all channels when receiving the
3695 Also, do not remove the client entry when giving the KILL
3696 command but when the KILLED notify is received.
3698 * Removed silc_idlist_find_client_by_nickname from the server.
3699 Not needed anymore. Affected files silcd/idlist.[ch].
3701 * Implemented the CHANNEL_CHANGE notify type handling to the
3702 server. Affected file silcd/server.c.
3706 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added silc_server_send_notify_invite to send the INVITE
3709 notify between routers.
3711 * Implemented the INVITE command correctly to the server.
3713 * Implemented the INVITE notify type handling in the server.
3715 * Implemented the INVITE command to the client library and on the
3718 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Added function silc_server_get_client_resolve to find the
3721 client entry by ID from all ID lists and then resolve it
3722 (using WHOIS) if it cannot be found. Affected file is
3725 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Implemented the BAN command to the client library.
3729 * The JOIN command in the server now checks the invite list
3732 * Changed the silc_command_reply_payload_encode_va and the
3733 silc_command_payload_encode_va to support that if argument is
3734 NULL it ignores and checks the next argument. Affected file
3735 lib/silccore/silccommand.c.
3737 * Added silc_server_send_notify_ban to send the BAN notify
3738 type between routers.
3740 * Chaned the silc_notify_payload_encode to support that if
3741 argument is NULL it ignores and checks the next argument.
3742 Affected file lib/silccore/silcnotify.c.
3744 * Tested ban lists in router environment successfully.
3746 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Implemented BAN command to the server, in silcd/command.[ch].
3750 * Removed the BAN and INVITE_LIST modes from the CMODE command
3753 * Added function silc_string_match to regex match two strings.
3754 Affected files lib/silcutil/silcutil.[ch].
3756 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Redefined parts of the SilcChannelEntry in the server to support
3759 the new ban and invite lists.
3761 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Redefined the INVITE command. The same command can be used to
3764 invite individuals to the channel but also to manage the invite
3765 list of the channel (to add to and remove from the invite list).
3766 Updated the protocol specs.
3768 * Added new command SILC_COMMAND_BAN that can be used to manage
3769 the ban list of the channel. Updated the protocol specs.
3771 * Removed the channel modes: the SILC_CMODE_BAN and the
3772 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3773 in the CMODE command. The equivalent features are now available
3774 using INVITE and BAN commands. Updated the protocol specs.
3776 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3777 in the network about change in the current ban list. The notify
3778 type is not used by the client.
3780 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3781 support the invite lists.
3783 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added new function silc_string_regexify that converts string
3786 including wildcard characters into regex string that can
3787 be used by the GNU regex library. Added into the file
3788 lib/silcutil/silcutil.[ch].
3790 Added silc_string_regex_combine to combine to regex strings
3791 into one so that they can be used as one regex string by
3792 the GNU regex library. Added into the file
3793 lib/silcutil/silcutil.[ch].
3795 Added silc_string_regex_match to match two strings. It returns
3796 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3798 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Imported GNU regex to the soruce tree into lib/contrib.
3801 Fixed some compiler warning from the regex.c.
3803 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Fixed MOTD command in the server to work in router environment.
3807 * Fixed the MOTD command in the client library to support
3808 the server argument in the command.
3810 * Added `nickname_len' argument to the silc_idlist_add_client
3811 in the server, as the `nickname' argument may be binary data
3814 * Added silc_idlist_get_channels to return all channels from
3817 * Implemented LIST command to the server. Affected file is
3820 * Implemented the LIST command to the client library and on the
3823 * Added [<user count>] argument to the LIST command reply.
3824 With private channels the user count is not shown.
3826 * Updated TODO and README.
3828 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * The client entry's data.registered must be TRUE even with
3831 global client entry on global client list. The data.registered
3832 is used to check whether the client is anymore in the network,
3833 for example with WHOWAS command so it must be valid.
3835 * Fixed the WHOWAS command in the server. It now actually works
3836 in router environment. Added function into silcd/command_reply.c
3837 silc_server_command_reply_whowas_save.
3839 * Added silc_idlist_purge function to the silcd/idlist.c
3840 to periodically purge the ID Cache.
3842 * Fixed INFO command in the server. It works now in router
3843 environment. Added <server name> argument to the INFO command
3844 reply. Updated the protocol specs.
3846 * Fixed minor bug in silc_idcache_purge to not purge if the
3847 expire value is zero.
3849 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3850 they were buggy because of the WHOWAS information.
3852 * Fixed local command MSG to handle the async resolving of
3853 the remote client properly. It used to fail the first MSG.
3854 Affected file silc/local_command.c.
3856 * Added `data_len' field to SilcIDCache context.
3858 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Update TODO. Todo in commands in the server.
3862 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3865 used by routers as broadcast packet to inform other routers
3866 about the changed user mode.
3868 Implemented the notify handling in the server. Affected file is
3869 silcd/packet_receive.c. Added the function
3870 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3872 * Added new generic Channel Payload and deprecated the New Channel
3873 Payload. The New Channel Payload is now the generic Channel
3876 * Added new argument `mode' to the silc_server_send_new_channel
3877 as it is required in the Channel Payload now.
3879 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3880 and created a new and real SilChannelPayload to represent the
3881 new generic Channel Payload. Implemented the encode/decode
3882 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3884 * Added silc_server_get_client_channel_list to return the list
3885 of channels the client has joined for WHOIS command reply.
3886 Affected file silcd/server.[ch].
3888 * Implemented the channel list sending in the WHOIS command reply
3889 in server and in the client.
3891 Implemented the channel list displaying on the user interface
3892 as well. Affected file silc/client_ops.c.
3894 * Added silc_channel_payload_parse_list to parse list of Channel
3895 Payloads. It returns SilcDList list of SilcChannelPayloads.
3896 Client for example can use this function to parse the list of
3897 channels it receives in the WHOIS command reply. The caller
3898 must free the list by calling silc_channel_payload_list_free.
3899 Affected files lib/silccore/silcchannel.[ch].
3901 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Added one new argument <user mode> to the WHOIS command reply
3904 to return the mode of the user in SILC. Updated the protocol
3907 Implemented it to the server and client.
3909 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Fixed the mode printing on the user interface on joining.
3912 Affected file silc/client_ops.c.
3914 * Implemented the UMODE command and user modes in general to the
3915 client library and to the user interface.
3917 * Implemented the UMODE command to the server.
3919 * The server now sends UNKNOWN_COMMAND error status if client sends
3920 unknown command. Affected file silcd/command.c.
3922 * All server commands now handle the command identifier the right
3923 way when sending the command reply to the client. The client can
3924 use to identify the command replies with the identifier.
3926 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Added silc_server_get_client_route to resolve the route to
3929 the client indicated by the client ID. Affected file is
3932 * Added silc_server_relay_packet as general function to relay
3933 packet to arbitrary destination. This deprecates functions
3934 like _send_private_message_key, _relay_notify etc. Affected
3935 file is silcd/packet_send.[ch].
3937 Removed silc_server_send_key_agreement,
3938 silc_server_send_private_message_key and
3939 silc_server_packet_relay_notify functions from the file
3940 silcd/packet_send.[ch].
3944 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3945 server. Affected file silcd/packet_receive.[ch].
3947 * Implemented the KILL command to the client. Implemented the
3948 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3949 Affected files lib/silcclient/command[_reply].c and
3950 lib/silcclient/client_notify.c. Implemented the KILL notify
3951 printing in the user inteface.
3953 * Fixed a lot silc_parse_nick memory leaks from the client
3954 library in the file lib/silcclient/command.c.
3956 * Changed the silc_server_send_notify_on_channels's `sender'
3957 argument from SilcSocketConnection to SilcClientEntry to
3958 check the sender as entry and not as connection object and not
3959 to send to the client provided as argument. The affected file
3960 is silcd/packet_send.[ch].
3962 * The notify packets that are destined directly to the client used
3963 to not to be processed by the server. Now changed that and the
3964 server processes all notify packets. After relaying the packet
3965 to the client the notify packet is processed in the server.
3967 * The silc_server_free_client_data now checks whether there is
3968 pending outgoing traffic for the client and purges the data to
3969 the network before removing the client entry.
3971 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3974 an client is killed from the SILC Network. Updated the protocol
3977 Added new function silc_server_send_notify_killed to the
3978 silcd/packet_send.[ch].
3980 * Added function silc_server_packet_relay_notify to relay notify
3981 packets that are destined directly to a client. In this case
3982 the server does not process the notify packets but merely relays
3983 it to the client. Affected file silcd/packet_send.[ch].
3985 Added also silc_server_packet_process_relay_notify to check
3986 whereto relay the notify. Affected file is
3987 silcd/packet_receive.[ch].
3989 * Implemented the KILL command to the server.
3993 * Added the backup schema desgined last fall to the protocol
3994 specs for everyone to see. The specification is in the
3995 *-spec-xx.txt draft and the packet type definitions for the
3996 backup routers is in *-pp-xx.txt draft. Thusly, added also
3997 new packet type SILC_PACKET_CELL_ROUTERS.
3999 * A big security problem in the implementation discovered. The
4000 signoff of an client did not cause new channel key generation
4001 which it of course should've done. The channel keys must be
4002 always re-generated when client leaves (or signoffs) the channel.
4003 The silc_server_remove_from_channels funtion now handles
4004 the channel key re-generation.
4006 * Added `sender' argument to the silc_server_send_notify_on_channels
4007 to not to send the client provided as argument. Affected file
4008 silcd/packet_send.[ch].
4010 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Implemented OPER and SILCOPER commands into the server and
4015 * Added silc_auth_verify and silc_auth_verify_data to verify
4016 the authentication directly from the authentication payload.
4017 It supports verifying both passphrase and public key based
4018 authentication. Affected file lib/silccore/silcauth.[ch].
4020 * Added `hash' field to the SilcIDListData structure. It is the
4021 hash negotiated in the SKE protocol. Affected file is
4024 * Slight redesigning of the SilcAuthPayload handling routines.
4025 Do not send SilcPKCS but SilcPublicKey as argument.
4027 * Implemented the public key authentication support to the
4028 serverconfig. The public key is loaded from the provided path
4029 and saved as authentication data to void * pointer. Thus,
4030 changed the unsigned char *auth_data to void *auth_data;
4032 * Fixed SHUTDOWN command to send the reply before the server
4033 is shutdown. :) Affected file silcd/command.c.
4035 * Fixed fatal bug in CONNECT command. The hostname was invalid
4036 memory and server crashed. Affected file silcd/command.c.
4038 * Fixed fatal bug in CLOSE command. The server_entry became
4039 invalid but was referenced later in the command. Affected file
4042 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Fixed fatal bug in failure packet handling. Server ignored
4045 the failure and thus crashed when it came.
4049 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4052 that the command may be executed only once in (about) 2 seconds.
4053 The old SILC_CF_LAG flag is same but allows command bursts up
4054 to five before limiting.
4056 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4057 server code. Various commands now includes the CF_LAG_STRICT
4058 flag to disallow any kind of miss-use of the command.
4060 * Fixed the silc_buffer_unformat to not to allocate any data
4061 if the length of the data is zero. It used to allocate the
4062 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4064 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Changed the format of AdminConnection configuration section
4067 in the server. Added username of the admin to the format.
4068 Affected files silcd/serverconfig.[ch].
4070 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4071 to return admin configuration data by host, username and/or
4074 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Implemented WHOWAS command to the server. Added the functions:
4078 silc_server_command_whowas_parse,
4079 silc_server_command_whowas_send_reply,
4080 silc_server_command_whowas_from_client and
4081 silc_server_command_whowas_from_server
4083 * Added <Client ID> argument to the WHOWAS command reply. Updated
4084 the protocol specs accordingly.
4086 * Implemented WHOWAS command and command_reply to the client
4089 Implemented the WHOWAS printing on the user interface.
4091 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Added new argument to the WHOWAS command reply, the real name.
4094 It is an optional argument. Updated the protocol specs.
4096 * Added SilcIDCacheDestructor callback that is registered when
4097 the SilcIDCache is allocated. The callback is called when
4098 an cache entry in the ID Cache expires, or is purged from the
4099 cache. Added into lib/silccore/idcache.[ch].
4101 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4102 to destruct the client entries when the cache entry expires.
4103 Other ID Cache's in server and in the client library ignores
4106 * If the ID Cache entry's `expire' field is zero then the entry
4107 never expires. Added boolean `expire' argument to the
4108 silc_idcache_add function in the lib/silccore/idcache.[ch].
4109 If it is TRUE the default expiry value is used.
4111 * Added silc_server_free_client_data_timeout that is registered
4112 when client disconnects. By default for 5 minutes we preserve
4113 the client entry for history - for WHOWAS command.
4115 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Added support to the server to enforce that commands are not
4118 executed more than once in 2 seconds. If server receives
4119 commands from client more frequently, timeout is registered
4120 to process the commands. Affected file silcd/command.c.
4121 Added new function silc_server_command_process_timeout.
4123 * Changed NICK_NOTIFY handling in client library to check that
4124 if the client's nickname was changed, so there is no need to
4125 resolve anything from the server.
4127 * Removed error printing from the WHOIS and IDENTIFY commands.
4128 If error occurs then it is ignored silently in the client library.
4129 The application, however, may map the received error to
4130 human readable error string. The application currently maps
4131 the NO_SUCH_NICKNAME error to string.
4133 * Made the command status message public to the application. Moved
4134 them from lib/silcclient/command_reply.c to
4135 lib/silcclient/command_reply.h. The application can map the
4136 received command status to the string with the
4137 silc_client_command_status_message function.
4139 * Added check to the server to check that client's ID is same
4140 as the Source ID in the packet the client sent. They must
4143 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Added dist-bzip hook to the Makefile.am to make bzip2
4146 compressed distributions.
4148 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Server now enforces the maximum length for the nickname and
4151 the channel as protocol specification dictates. 128 bytes for
4152 nickname and 256 bytes for channel name.
4154 * Moved the WHOIS printing to the application. The client libary
4155 does not print out the WHOIS information anymore, the application
4156 must do it. Renamed silc_client_command_reply_whois_print to
4157 the silc_client_command_reply_whois_save.
4159 The client's idle time is also sent to the application now, and
4160 the idle is shown on screen.
4162 * Added silc_client_command_reply_identify_save to save the
4163 received IDENTIFY entries.
4165 * Do not check for channel private keys in message sending and
4166 reception if the channel does not have the PRIVKEY mode set.
4167 Affected file lib/silclient/client_channel.c.
4169 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4172 just surfaced after chaning the JOIN procedure.
4174 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added silc_client_get_clients_by_list to get client entries
4177 from Client ID list, that is returned for example by JOIN
4178 and USERS command replies. The application should use this
4179 function for example when JOIN command reply is received to
4180 resolve the clients already on the channel (library does not
4181 do that anymore as USERS command reply is not used in the JOIN
4182 procedure anymore). Affected files lib/silcclient/silcapi.h and
4183 lib/silcclient/idlist.c.
4185 * JOIN command reply and USERS command reply returns now SilcBuffer
4186 pointers instead of unsigned char pointers when returning
4187 the client list and mode list.
4189 * Added <Client ID> argument to the JOIN command reply, mainly
4190 for the server to identify for which client the command was
4191 originally sent. Updated protocol specs accordingly.
4193 * Added SilcDlist private_key pointer to the SilcChannelEntry
4194 in the client to support the channel private keys. Affected
4195 file is lib/silcclient/idlist.h.
4197 * Added SilcChannelPrivateKey argument to the function
4198 silc_client_send_channel_message so that application can choose
4199 to use specific private ke if it wants to. If it is not provided,
4200 the normal channel key is used, unless private keys are set.
4201 In this case the first (key that was added first) is used
4202 as the encryption key.
4204 * Implemented the support for channel private key handling.
4205 Implemented the following functions:
4207 silc_client_add_channel_private_key,
4208 silc_client_del_channel_private_keys,
4209 silc_client_del_channel_private_key,
4210 silc_client_list_channel_private_keys and
4211 silc_client_free_channel_private_keys
4213 Affected file lib/silcclient/client_channel.c.
4215 * Added the support for the private keys in the channel message
4216 sending and encryption and in the message reception and
4217 decryption. Affected funtions are
4218 silc_client_send_channel_message and silc_client_channel_message.
4220 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Added SKE's key verify callback to the client library's
4223 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4225 * Removed the statement that server (or router) must send USERS
4226 command reply when joining to the channel so that the client
4227 knows who are on the channel. Instead, the client list and
4228 client's mode list is now sent in the JOIN command reply to the
4229 client who joined channel. This is better solution.
4231 * Added function silc_server_get_users_on_channel and function
4232 silc_server_save_users_on_channel to the silcd/server.[ch].
4234 * Removed function silc_server_command_send_users from the
4237 * Do not show topic on the client library anymore. The topic is
4238 sent in the command reply notify to the application and the
4239 application must show the topic now.
4241 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Added client searching by nickname hash into the IDENTIFY and
4244 WHOIS commands in the server as they were clearly missing from
4245 them. Affected file is silcd/command.c.
4247 * Fixed a bug in private message receiving in the client library.
4248 The remote ID was freed and it wasn't supposed, now it is
4251 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Minor fix to the channel payload; allocate the data area, as it
4254 needs to be of specific length.
4256 * If the key agreement port is zero then the operating
4257 system will define the bound port. Affected files are
4258 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4260 * Added new function silc_channel_payload_decrypt into the file
4261 lib/silccore/silcchannel.[ch].
4263 * Moved the channel message etc, check from silc_packet_decrypt
4264 to applications. The library calls now a generic
4265 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4266 when the packet is either normal or special. This was done to
4267 allow more wide range of checking that was not allowed when
4268 the code was in library. Now applications can do virtually any
4269 checks to the packet and return to the library the decision how
4270 the packet should be processed. Affected files are
4271 lib/silccore/silcpacket.[ch].
4273 Added silc_server_packet_decrypt_check to the server and
4274 silc_client_packet_decrypt_check to the client library.
4276 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4277 to send with specified source and destination information.
4279 * Channel message delivery between routers was broken after the
4280 channel key distribution was fixed earlier. The channel key
4281 was used be to distributed to other routers as well which is not
4282 allowed by the protocol. Now this is fixed and channel keys
4283 really are cell specific and the channel message delivery between
4284 routers comply with the protocol specification.
4286 * Fixed various commands in server to check also the global list
4287 for the channel entry and not just the local list. The affected
4288 file silcd/command.c.
4290 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Added assert()s to buffer formatting and unformatting routines
4293 to assert (if --enable-debug) when error occurs. Affected
4294 file: lib/silcutil/silcbuffmt.c.
4296 * Changed to auto-reconnect to check whether the remote host is
4297 router and register the re-connect timeout if it is. It used
4298 to check that whether we are normal server, but router must do
4299 auto-reconnect with another router as well. Affected file
4302 * Removed the [<key len>] option from CMODE command as the cipher
4303 name decides the key length, nowadays. See the defined ciphers
4304 from the protocol specification.
4306 * Added [<hmac>] option to the CMODE command to define the HMAC
4307 for the channel. Added SILC_CMODE_HMAC channel mode.
4309 * Added [<hmac>] option for the JOIN command so that user can
4310 select which HMAC is used to compute the MACs of the channel
4313 * Added Hmac field to the Channel Message Payload. The integrity
4314 of plaintext channel messages are now protected by computing
4315 MAC of the message and attaching the MAC to the payload. The
4316 MAC is encrypted. Now, it is clear that this causes some
4317 overhead to the size of the packet but rationale for this is that
4318 now the receiver can verify whether the channel message decrypted
4319 correctly and also when private keys are set for the channel the
4320 receiver can decrypt the packet with several keys and check from
4321 the MAC which key decrypted the message correctly.
4323 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4324 lib/silccrypt/silccipher.[ch].
4326 * Added silc_hash_len to return the digest length into the
4327 lib/silcrypt/silchash.[ch].
4329 * Rewrote parts of Silc Channel Payload interface in the
4330 lib/silccore/silcchannel.[ch]. The encode function now also
4331 encrypts the packet and parse function decrypts it.
4333 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Fixed a minor formatting bug in the SKE's key material processing.
4336 It actually might have processed the keys wrong way resulting
4339 * Redefined the mandatory HMAC algorithms and added new algorithms.
4340 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4341 and hmac-md5 truncated to 96 bits. The mandatory is now
4342 hmac-sha1-96. Rest are optional (including the one that used
4343 to be mandatory). Rationale for this is that the truncated HMAC
4344 length is sufficient from security point of view and can actually
4345 make the attack against the HMAC harder. Also, the truncated
4346 HMAC causes less overhead to the packets. See the RFC2104 for
4349 * Added new [hmac] configuration section. The SKE used to use
4350 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4351 is of course wrong. The official names that must be proposed in
4352 the SKE are the ones defined in the protocol specification
4353 (hmac-sha1-96 for example). The user can configure any hmac
4354 using any hash function configured in the [hash] section. At
4355 least, the mandatory must be configured.
4357 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4359 * Added HMAC list to the SKE proposal list. It has now both
4360 hash algorithm list and HMAC list. This makes the protocol
4361 incompatible with previous versions. The SKE now seems to work
4362 the way it is supposed to work, for the first time actually.
4364 * Defined plain Hash algorithms to the protocol specification.
4367 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Implemented support for key agreement packets into the server.
4370 Added functions silc_server_key_agreement and
4371 silc_server_send_key_agreement. Other than these functions,
4372 server has nothing to do with this packet.
4374 * Added support for private message key packets into the server.
4375 Added functions silc_server_private_message_key and
4376 silc_server_send_private_message_key.
4380 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4381 called in the protocol's final callback instead in the END
4382 protocol state. This makes a little more sense and in the same
4383 time in client we can use the same protocol routines for normal
4384 key exchange and to key agreement packet handling as well.
4386 * Added to both client's and server's KE protocol context the
4387 SilcSKEKeyMaterial pointer to save the key material. We will
4388 bring the key material to the protocol's final callback by doing
4389 this. The final callback must free the key material.
4391 * Added SKE's packet_send callback into client's KE protocol
4392 context so that the caller can choose what packet sending function
4393 is used. This way we can use different packet sending when
4394 doing normal SKE when doing key agreement packet handling (in
4395 the key agreement packet handling we do not want to encrypt
4398 * Implemented the responder side of the key agreement routines
4399 in the client. The client can now bind to specified port and
4400 accept incoming key negotiation. The key material is passed
4401 to the application after the protocol is over.
4403 * Implemented the processing of incoming Key Agreement packet
4404 in the client. Added function silc_client_key_agreement to
4407 * Implemented the intiator side of the key agreement routines
4408 in the client. The client can now initiate key agreement with
4409 another remote client. The key material is passed to the
4410 application after the protocol is over.
4412 * Created client_keyagr.c to include all the key agreement
4415 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4416 SILC_TASK_CALLBACK except that it is not static.
4418 * Created client_notify.c and moved the Notify packet handling
4419 from the client.[ch] into that file.
4421 * Created client_prvmsg.c and moved all private message and
4422 private message key routines from the client.[ch] into that file.
4424 * Create client_channel.c and moved all channel message and
4425 channel private key routines from the client.[ch] into that file.
4427 * Changed silc_client_get_client_by_id_resolve to resolve with
4428 WHOIS command instead of IDENTIFY command, in the file
4429 lib/silclient/idlist.c.
4431 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Implemented the SKE's responder side to the Client library.
4435 * When FAILURE is received to the protocol do not trust it
4436 blindly. Register a timeout to wait whether the remote closes
4437 the connection as it should do it, only after that process the
4438 actual failure. This was changed to both client and server.
4440 * Added client_internal.h to include some of the structures
4441 there instead of client.h in lib/silcclient/.
4443 * Added function silc_task_unregister_by_callback to unregister
4444 timeouts by the callback function.
4446 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Some "Incomplete WHOIS info" errors has been appearing on the
4449 log files. Took away the entry->userinfo check from WHOIS
4450 reply sending. The entry->userinfo is now " " if client did not
4451 provide one. I thought this was fixed earlier but something
4452 is wrong still. Let's see if the error still appears.
4454 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Fixed a minor bug in the login when the channel key is
4457 re-generated in the server. It used to generate the key in
4458 wrong order and thus caused problems in the channel traffic.
4460 * Fixed a minor bug in channel key distsribution after
4461 KICK command. The key was not sent to the router even though
4464 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added silc_ske_process_key_material_data as generic routine
4467 to process any key material as the SILC protocol dictates. The
4468 function is used by the actual SKE library but can be used by
4469 applications as well. This relates to the private message keys
4470 and the channel private keys since they must be processed the
4471 same way the normal SILC session keys. The protocol dictates
4472 this. Affected files: lib/silcske/silcske.[ch].
4474 Added also silc_ske_free_key_material to free the
4475 SilcSKEKeyMaterial structure.
4477 * Defined silc_cipher_set_key function to set the key for
4478 cipher without using the object's method function. The affected
4479 files: lib/silccrypt/silccipher.[ch].
4481 * Implemented silc silc_client_add_private_message_key,
4482 silc_client_add_private_message_key_ske,
4483 silc_client_del_private_message_key,
4484 silc_client_list_private_message_keys and
4485 silc_client_free_private_message_keys functions in the
4488 Added functions silc_client_send_private_message_key to send
4489 the Private Message Key payload and silc_client_private_message_key
4490 to handle incoming Private Message Key payload.
4492 * Added Cipher field to the Private Message Key payload to set
4493 the cipher to be used. If ignored, the default cipher defined
4494 in the SILC protocol (aes-256-cbc) is used.
4496 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Removed lib/silcclient/ops.h file.
4500 Redefined parts of the SILC Client Library API. Created new
4501 file silcapi.h that deprecates the ops.h file and defines the
4502 published Client Library API. Defined also private message key
4503 API and channel private key API into the file.
4505 This is the file that the application must include from the
4506 SILC Client Library. Other files need not be included by
4507 the application anymore.
4509 * Added new key_agreement client operation callback and also
4510 defined the Key Agreement library API for the application.
4512 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4515 is used by clients to request key negotiation between another
4516 client in the SILC network. If the negotiation is started it
4517 is performed using the SKE protocol. The result of the
4518 negotiation, the secret key material, can be used for example
4519 as private message key.
4521 Implemented the Key Agreement payload into the files
4522 lib/silccore/silauth.[ch].
4524 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Redefined ciphers for the SILC protocol. Added some new ciphers
4527 and defined the key lengths for the algorithms. Changed the
4528 code accordingly. The default key length is now 256 bits.
4530 * Fixed SKE key distribution function silc_ske_process_key_material
4531 when the key length is more than 128 bits. The default key
4532 length in SILC is now 256 bits.
4534 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4535 to indicate unsupported algorithm.
4537 * Renamed rijndael.c to aes.c and all functions as well.
4539 * Fixed a long standing channel key setting bug in client library.
4540 Weird that it has never surfaced before.
4542 * Fixed bug in channel deletion. If the entire channel is removed
4543 then it must also delete the references of the channel entry
4544 from the client's channel list as the client's channel entry and
4545 the channel's client entry share same memory.
4547 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Implemented CONNECT and SHUTDOWN commands in the client.
4551 * Implemented CLOSE command to the client.
4553 * Added the function silc_idlist_find_server_by_name into the
4554 files silcd/idlist.[ch].
4556 Added the function silc_idlist_find_server_by_conn into the
4557 files silcd/idlist.[ch].
4559 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * DIE command was renamed to SHUTDOWN. Updated the both code
4564 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4565 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4567 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4570 * Added function silc_server_create_connection function to create
4571 connection to remote router. My server implementation actually
4572 does not allow router to connect to normal server (it expects
4573 that normal server always initiates the connection to the router)
4574 so the CONNECT command is only good for connecting to another
4577 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4580 or some other client was kicked from the channel.
4582 Implemented the handling of the notify type to both client
4585 Implemented silc_server_send_notify_kicked to send the KICKED
4586 notify. It is used to send it to the server's primary router.
4588 * Implemented the KICK command into server and client.
4590 * Added `query' argument to the silc_idlist_get_client function
4591 to indicate whether to query the client from server or not if
4594 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4595 to indicate that the client is not channel founder.
4599 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Removed the rng context from SilcPacketContext structure and
4602 changed that the packet routine uses the Global RNG API.
4604 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Added support for quit message that client can "leave" on the
4607 channel when it quits the SILC. It is ditributed inside the
4608 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4610 Added silc_server_free_client_data that will take the
4611 signoff message as argument.
4613 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4615 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Updated parts of the protocol specification to keep it up
4620 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4623 payloads in one packet.
4625 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4626 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4627 use now the new List flag.
4629 * Also deprecated the following packet types: REPLACE_ID,
4630 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4632 * Added list support for Notify packet in server.
4634 * Added silc_server_send_notify_channel_change to send the
4635 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4636 the silc_server_send_replace_id.
4638 * Added silc_server_send_notify_nick_change to send the
4639 NICK_CHANGE notify type. Deprecates the function
4640 silc_server_send_replace_id.
4642 * Added silc_server_send_notify_join to send the JOIN notify type.
4643 Deprecates the function silc_server_send_new_channel_user.
4645 * Added silc_server_send_notify_leave to send LEAVE notify type.
4646 Deprecates the function silc_server_send_remove_channel_user.
4648 * Added silc_server_send_notify_cmode and
4649 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4650 types. Deprecates the silc_server_send_set_mode function.
4652 * Added SERVER_SIGNOFF notify type to indicate that server has
4653 quit. This means that all clients on the channel from that
4654 server will drop. This can be also used when netsplit happens.
4656 Deprecated REMOVE_ID packet type since it is not needed anymore
4659 Added silc_server_send_notify_server_signoff to send the
4660 SERVER_SIGNOFF notify type. Deprecates the function
4661 silc_server_send_remove_id.
4663 Added also silc_server_send_notify_signoff to send the
4664 SIGNOFF notify type.
4666 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4667 SILC protocol from this day on. Changed the protocol
4668 specification as well.
4670 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4671 notify type. It is used between routers to notify about
4672 topic changes on a channel.
4674 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4677 * Partly updated the protocol specification to comply with the
4678 changes now made. It is still though a bit outdated.
4680 * The JOIN notify type now takes one extra argument <Channel ID>.
4681 The packet used to be destined to the channel but now the
4682 JOIN type may be sent as list thus it is impossible to
4683 destine it to any specific channel. By adding this argument
4684 it is again possible.
4686 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added CREDITS file. The CHANGES and CREDITS file will appear
4689 in the distribution as well.
4691 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4694 types in the server's silcd/packet_receive.c.
4696 * Implemented CMODE and CUMODE to work in router environment.
4698 * Fixed minor encoding and decoding buglet from the
4699 lib/silccore/silcmode.c.
4701 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4704 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4706 * Changed all SilcConfigServer* and silc_config_server* to
4707 SilcServerConfig* and silc_server_config*, respectively.
4710 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Associated the ID (client or server ID) to the Authentication
4713 Payload to avoid any possibility of forging. Updated the
4714 protocol specification and the code accordingly.
4716 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * The RSA key length is now save to the RsaKey context in the
4719 key generation process in lib/silccrypt/rsa.c. The key length
4720 is now used to figure out the maximum size of the block allowed
4721 to be encrypted/signed.
4723 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4724 is equivalent to the silc_mp_mp2bin but does not allocate any
4727 * Changed silc_mp_mp2bin API to take length argument. If it is
4728 non-zero then the buffer is allocated that large. If zero, then
4729 the size is approximated using silc_mp_sizeinbase, which however
4732 * Created Global RNG API which is global RNG that application can
4733 initialize. After initializing, any routine anywhere in the
4734 code (including library) can use RNG without allocating a new
4735 RNG object. This was done to allow this sort of use of the
4736 RNG in code that has no chance to allocate RNG object. All
4737 applications currently allocate this and many routines in the
4738 library use this. Affected file lib/silccrypt/silcrng.[ch].
4740 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4741 it to use the Global RNG API.
4743 * Defined Authentication Payload into protocol specification that
4744 is used during SILC session to authenticate entities. It is
4745 used for example by client to authenticate itself to the server
4746 to obtain server operator privileges.
4748 Implemented this payload into the lib/silccore/silcauth.[ch].
4749 Implemented also routines for public key based authentication
4750 as the new protocol specification dictates.
4752 Moved definitions of different authentication methods from
4753 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4755 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4756 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4757 silc_pkcs_verify_with_hash functions into the file
4758 lib/silccrypt/silcpkcs.[ch].
4760 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * The client entry's userinfo pointer must be always valid.
4763 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4764 will fail since it requires the userinfo. Now, the userinfo
4765 is allocated as "" if actual userinfo does not exist. Actually,
4766 it must exist and it is totally Ok to drop client connections
4767 that does not announce the userinfo. However, we will make
4768 this workaround for now.
4770 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4771 to return the remote port by socket.
4773 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4776 SILC_SERVER_PENDING_EXEC and added an new macro
4777 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4778 data or when error occurs while processing the pending command.
4780 Added new argument `destructor' into silc_server_command_pending
4781 and to the SilcServerCommandPending object. This destructor is
4782 now called after calling the pending callback or if error occurs
4783 immediately. If error occurs the actual pending callback won't
4784 be called at all - only the destructor. The destructor may be
4785 NULL if destructor is not needed.
4787 All this applies for client library code as well. Similar
4788 changes were made there as well for the pending commands.
4790 In the client, the application must now allocate the
4791 SilcClientCommandContext with the silc_client_command_alloc
4794 * Added reference counter to the SilcServerCommandContext. Added
4795 function silc_server_command_alloc and silc_server_command_dup
4798 Same type of functions added to the client library for the same
4801 * Removed the cmd_ident from IDListData away since it is now
4802 global for all connections. It is the command identifier used
4803 in command sending and with pending commands. The affected file
4806 * Added reference counter to the SilcSocketConnection objecet to
4807 indicate the usage count of the object. The object won't be
4808 freed untill the reference counter hits zero. Currently only
4809 server uses this, and client ignores it. The client must be
4810 set to use this too later. The affected files are
4811 lib/silccore/silcsockconn.[ch]. Added also the function
4812 silc_socket_dup to increase the reference counter.
4814 This was mainly added because it is possible that the socket
4815 is removed underneath of pending command or other async
4816 operation. Now it won't be free'd and proper DISCONNECTING
4817 flags, etc. can be set to avoid sending data to connection that
4818 is not valid anymore.
4820 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4821 the connection. After that it sets SILC_SET_DISCONNECTED.
4822 It is, however, possible that the socket data is not still freed.
4823 The silc_server_packet_process now checks that data is not
4824 read or written to connection that is DISCONNECTED. The socket
4825 get's freed when the reference counter hits zero.
4827 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Changed the client operation API: channel_message operation's
4830 `sender' is now the client entry of the sender, not the nickname
4831 and the `channel' is the channel entry, not the channel name.
4833 In the private_message operation the `sender' is now also the
4834 client entry of the sender not the nickname.
4836 Affected file is lib/silcclient/ops.h and all applications
4837 using the client operations.
4839 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Moved the calling of ops->connect() from connect_to_server_final
4842 into receive_new_id functin since that is the point when the
4843 client is actually allowed to send traffic to network. The
4844 affected file is lib/silcclient/client.c.
4846 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4849 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4850 (if needs broadcasting) instead of broadcasting the packets one
4851 by one which would make a burst in the network traffic.
4853 * Added `broadcast' argument to the functions in silcd/server.[ch]
4854 silc_server_create_new_channel[_with_id] to indicate whether
4855 to send New Channel packet to primary router.
4857 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Added new function into the silcd/server.[ch] files:
4860 silc_server_create_new_channel_with_id to create new channel with
4861 already existing Channel ID.
4863 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4864 lib/silccore/silcpacket.h. This packet is used t send list of
4865 Set Mode payloads inside one packet. Server uses this to set
4866 the modes for the channels and clients on those channels, that it
4867 announced to the router when it connected to it. The protocol
4868 specification has been updated accordingly.
4870 * The silc_server_new_channel did not handle the packet coming
4871 from normal server as it normally does not send that. However,
4872 when it announces its channels it does send it. Implemented
4873 the support for that.
4875 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4876 into the file lib/silccore/id.h.
4878 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Fixed memory leaks in the functions silc_idlist_del_client,
4881 silc_idlist_del_channel and silc_idlist_del_server in the file
4882 silcd/idlist.c. All of those leaked like a sieve.
4884 * Fixed some small memory leaks in the client's function
4885 silc_client_notify_by_server.
4887 * Added functions into silcd/server.c: silc_server_announce_clients,
4888 silc_server_announce_channels and silc_server_announce_server.
4889 These functions are used by normal and router server to announce
4890 to its primary router about clients, channels and servers (when
4891 router) that we own. This is done after we've connected to the
4894 These functions effectively implements the following packet types:
4895 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4896 and SILC_PACKET_NEW_ID_LIST.
4898 * Added new functions into the silcd/packet_receive.[ch]:
4899 silc_server_new_id_list, silc_server_new_channel_list and
4900 silc_server_new_channel_user_list to handle the incoming
4901 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4903 * Added support of changing Channel ID in the function
4904 silc_server_replace_id. If the server that announces a channel
4905 to the router already exists in the router (with same name but
4906 with different Channel ID), router is responsible to send
4907 Replace ID packet to the server and force the server to change
4908 the Channel ID to the one router has.
4910 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4911 client that the Channel ID has been changed by the router. The
4912 normal server sends this to the client. Client must start using
4913 the new Channel ID as the channel's ID.
4915 Implemented handling of this new type into lib/silcclient/client.c
4916 into the function silc_client_notify_by_server.
4918 * Added new function silc_idlist_replace_channel_id into the files
4919 silcd/idlist.[ch] to replace the Channel ID.
4921 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Call silc_server_command_identify_check always when processing
4924 the IDENTIFY command in silcd/command.c
4926 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4929 send keepalive packets. The packet can be sent by clients,
4930 servers and routers.
4932 Added function silc_socket_set_heartbeat into the file
4933 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4934 If not set, the heartbeat is not performed. The actual
4935 heartbeat is implemented in the low level socket connection
4936 library. However, application is responsible of actually
4939 Added silc_server_send_heartbeat to send the actual heartbeat
4940 packet into silcd/packet_send.[ch]. Server now performs
4941 keepalive with all connections.
4943 * Added silc_task_get_first function into lib/silcutil/silctask.c
4944 to return the timeout task with shortest timeout. There was a bug
4945 in task unregistration that caused problems. TODO has been
4946 updated to include that task system must be rewritten.
4948 * The client library will now resolve the client information when
4949 receiving JOIN notify from server for client that we know but
4950 have incomplete information.
4952 * Rewrote parts of silc_server_remove_from_channels and
4953 silc_server_remove_from_one_channel as they did not remove the
4954 channel in some circumstances even though they should've.
4956 * Encryption problem encountered in server:
4958 The LEAVE command used to send the Channel Key packet to the
4959 router immediately after generating it. However, the code
4960 had earlier sent Remove Channel user packet but not immediately,
4961 ie. it was put to queue. The order of packets in the router
4962 was that Channel Key packet was first and Remove Channel User
4963 packet was second, even though they were encrypted in the
4964 reverse order. For this reason, MAC check failed. Now, this
4965 is fixed by not sending the Channel Key packet immediately but
4966 putting it to queue. However, this is more fundamental problem:
4967 packets that are in queue should actually not be encrypted
4968 because packets that are sent immediately gets encrypted
4969 actually with wrong IV (and thus MAC check fails). So, packets
4970 that are in queue should be encrypted when they are sent to
4971 the wire and not when they put to the queue.
4973 However, the problem is that the current system has not been
4974 designed to work that way. Instead, the packet is encrypted
4975 as soon as possible and left to the queue. The queue is then
4976 just purged into wire. There won't be any fixes for this
4977 any time soon. So, the current semantic for packet sending
4980 o If you send packet to remote host and do not force the send
4981 (the packet will be in queue) then all subsequent packets to the
4982 same remote host must also be put to the queue. Only after the
4983 queue has been purged is it safe again to force the packet
4986 o If you send all packets immediately then it safe to send
4987 any of subsequent packets through the queue, however, after
4988 the first packet is put to queue then any subsequent packets
4989 must also be put to the queue.
4991 Follow these rules and everything works fine.
4993 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added new function silc_server_remove_clients_by_server to
4996 remove all client entries from ID list when the server connection
4997 is lost. In this case it is also important to invalidate all
4998 client entires as they hold the invalid server entry. This
4999 fixes fatal bug when server has lost connection and will reconnect
5002 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Made some sanity checks to silc_server_daemonise like to check
5005 whether the requested user and group actually exists.
5007 * Added sanity check to SKE's silc_ske_responder_finish to check
5008 that the public and private key actually is valid.
5010 * Invalidate the client's nickname when receiving Replace ID
5011 packet and the Client ID is being replaced. This means that the
5012 server will query the nickname if someone needs it (client)
5015 * Sort the ID Cache in client library when the ID Cache data
5016 has changed (needs sorting).
5018 * Do not allow for SILC client to create several connections to
5019 several servers. The client does not support windows right now
5020 and generating multiple connections causes weird behaviour.
5022 Irssi-silc client does support windows and can handle several
5023 connections without problems, see: www.irssi.org and SILC plugin.
5025 * Fixed some places where client was added to the IDList. The
5026 rule of thumb is following (in order to get everything right):
5027 If the client is directly connected local client then the
5028 `connection' argument must be set and `router' argument must be
5029 NULL to silc_idlist_add_client function. If the client is not
5030 directly connected client then the `router' argument must
5031 bet set and the `connection' argument must be NULL to the
5032 silc_idlist_add_client function.
5034 * The funtion silc_server_packet_send_local_channel actually did
5035 not check whether the client was locally connected or not. It
5036 does that now. Fixed a bug related to LEAVE command.
5038 * Fixed Remove Channel User payload parsing bug in server's
5039 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5041 * The server's silc_server_save_channel_key now checks also the
5042 global ID list for the channel as it might not be in the local
5043 list. Fixed a bug related to LEAVE command.
5045 * Is this the end of the [<unknown>] buglet that has been lurking
5046 around for a long time? A little for loop fix in server's
5047 silc_server_command_whois_parse that is used by both IDENTIFY
5048 and WHOIS command. At least, this was a clear bug and a cause
5049 of one type of [<unknown>] buglet.
5051 * WHOIS and IDENTIFY commands call the function
5052 silc_server_command_[whois/identify]_check function even if
5053 we are not router server.
5055 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Added --with-gmp configuration option. If set the GMP
5058 is always compiled in the SILC source tree. If not set then
5059 it is checked whether the system has the GMP3 installed. If
5060 it has then the GMP won't be compiled (the system's headers
5061 and library is used), if it doesn't have it then the GMP is
5062 compiled in the SILC source tree.
5064 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Changed RSA private exponent generation to what PKCS #1
5067 suggests. We try to find the smallest possible d by doing
5068 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5069 not security fix but optimization.
5071 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Added new config entry [Identity] to fork the server and run
5074 it as specific user and group. A patch from Bostik.
5076 * Imported Dotconf configuration library into lib/dotconf.
5077 This will be used to create the SILC configuration files later.
5078 It will appear in the distsribution after this commit.
5080 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * A big code auditing weekend happening. Auditing code for
5083 obvious mistakes, bugs and errors. Also, removing any code
5086 Removed files for being obsolete:
5088 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5089 inline in the file lib/silcutil/silcbuffer.h)
5091 o lib/silcutil/silcbufutil.c (the header has inline versions)
5093 Changed code to fix possible error conditions:
5095 o The buffer formatting routines now check that the destination
5096 buffer really has enough space to add the data. This applies for
5097 both buffer formatting and unformatting
5098 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5099 unformatting was changed to accomodate following rules:
5100 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5101 sent to the function while XXX_*STRING will not allocate or copy
5102 the data into the buffer. Instead it sets the pointer from the
5103 buffer into the pointer sent as argument (XXX_*STRING used to
5104 require that the pointer must be allocated already). This change
5105 makes this whole thing a bit more consistent and more optimized
5106 (note that the data returned in the unformatting with XXX_*STRING
5107 must not be freed now). The routines return now -1 on error.
5109 o Tried to find all code that use buffer_format and buffer_unformat
5110 and added return value checking to prevent formatting and
5111 especially unformatting errors and possible subsequent fatal
5114 o Changed ske->x and ske->KEY to mallocated pointers in
5115 lib/silcske/silcske.h. Fixed possible data and memory leak.
5117 o Added return value checking to all *_parse* functions. Fixed
5118 many memory leaks as well.
5120 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5121 so that buffer overflows would not happen. All code now also
5122 checks the return value as it can fail.
5124 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * Added reconnection support to server if the normal server looses
5127 its connection to the router (for example if router is rebooted).
5128 The server performs normal reconnection strategy implemented
5129 to the server. Affected file silcd/server.c.
5131 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Added new packet type SILC_PACKET_SET_MODE that is used to
5134 distribute the information about changed modes (for clients,
5135 channels and clients channel modes) to all routers in the
5136 network. Updated the protocol specification accordingly.
5138 Added functions into silcd/packet_send.c and
5139 silcd/packet_receive.c: silc_server_send_set_mode,
5140 silc_server_set_mode.
5142 Added new files silcmode.[ch] into lib/silccore that implements
5143 the encoding and decoding of Set Mode Payload. Added new type
5144 SilcSetModePayload. Moved the definitions of different modes
5145 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5147 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Oops, a little mistake in server's connection authentication
5150 protocol. The protocol is not ended with FAILURE but with
5151 SUCCESS if the authentication is Ok. :) Affected file is
5154 * Implemented NICK_CHANGE notify handling in server in the file
5155 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5156 the local clients on the channel. After the changing nickname
5157 in router environment snhould work and the [<unknown>] nickname
5158 should appear no more.
5160 The silc_server_replace_id function that receives the Replace ID
5161 payload now sends the NICK_CHANGE notify type also in the file
5162 silcd/packet_receive.c
5164 * Changed WHOIS and IDENTIFY command to support the maximum amount
5165 of arguments defined in protocol specs (3328 arguments). This
5166 fixed a bug that caused problems when there were more than three
5169 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Added extra parameter, command identifier, to the
5172 silc_client_send_command so that explicit command identifier
5175 Changed that ID list routines uses specific command identifier
5176 when sending WHOIS/IDENTIFY requests to the server so that they
5177 can be identified when the reply comes back.
5179 Affected files lib/silcclient/command.[ch],
5180 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5182 * Added `sender' argument to silc_server_packet_send_to_channel
5183 to indicaet the sender who originally sent the packet to us
5184 that we are now re-sending. Ignored if NULL. Affected file
5185 silcd/packet_send.[ch].
5187 * Added some server statistics support in silcd/server_internal.h
5188 SilcServerStatistics structure and around the server code. Also
5189 send some nice statistics information when client is connecting
5192 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5194 * Fixed channel ID decoding in server's JOIN command reply in
5195 silcd/command_reply.c
5197 * Fixed braodcasting of replace ID payload to not to send it if
5198 we are standalone server in silcd/packet_receive.c.
5200 * Fixed all channel message sending routines to not to send
5201 packets to clients that has router set, since they are routed
5202 separately in the same function earlier. Affects file
5203 silcd/packet_send.c and all channel packet sending functions.
5205 * In USERS reply, res_argv[i] are not allocated, the table
5206 is allocated. Thus changed that free the table, not its
5209 * In server's whois_check and identify_check if the client is
5210 locally connected do not send any WHOIS commands - they are not
5213 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Fixed some minor bugs in client when sending WHOIS command. The
5216 arguments was in wrong order.
5218 * Removed statis function add_to_channel from server in
5219 silcd/command.c that was previously used with the joining but
5222 * Tested USERS command in router environment successfully with two
5223 routers, two servers and two clients.
5225 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Reorganized the USERS command and command reply in client library
5228 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5229 When the command is given by user we register a pending command
5230 callback that will reprocess the command after the reply has been
5231 received from the server. When reprocessing the packet we then
5232 display the information. Thus, the USERS information is displayed
5233 now in the command callback instead of in the command reply
5234 callback. The processing of the command is same as previously
5235 when server has sent the command reply in the JOINing process.
5237 * Added to USERS command in silcd/command_reply.c to join the client,
5238 we didn't use to know about, to the channel after we've created
5239 a client entry for it. Also, for clienet we did know already still
5240 check whether it is on the channel or not and add it if not.
5242 * Removed silc_server_command_join_notify as the function and its
5245 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Changed the client's pending command handling to the same as the
5248 server's pending command handling. It is also now possible to
5249 execute command reply functions from other command reply
5250 function as the function callbacks for commands and command
5251 replies are one and same. The pending commands are not static
5252 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5253 in client connection context. Thus, pending commands are server
5254 connection specific as it is convenient.
5256 Changed the function silc_client_command_pending and
5257 silc_client_command_pending_del and added new function
5258 silc_client_command_pending_check. Removed the
5259 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5262 * Added cmd_ident, current command identifier, to the client
5263 connection context in lib/silcclient/client.h to keep track on
5264 command identifiers used in command sending. Client's command reply
5265 function handling now supports the mandatory command identifiers.
5267 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5268 funtions in client to fully support pending command callbacks.
5270 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5271 as one of the arguments to the application in the command reply
5274 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5275 before first releasing SILC but came back. Now it is removed again
5276 and should come back nomore. The FORWARDED flag was used only
5277 by the JOINing procedure by forwarding the command packet to router.
5278 Now, the JOINing procedure has been changed to more generic (due
5279 to various router environment issues) and FORWARDED is not needed
5280 anymore for anything. The protocol specification is yet to be
5283 Now, removed silc_server_packet_forward from server and the flag
5284 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5286 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Renamed NAMES command to USERS command. The NAMES was named that
5289 due to historical reasons. Now it is renamed. Also, rewrote
5290 parts of the USERS command. The nickname list is not sent anymore
5291 by the server. Only Client ID and mode lists are sent in the USERS
5292 command. Changed this also to the protocol specification.
5294 The client now resolves the names and stuff after it receives
5295 the USERS list from the server when joining to the channel.
5297 * WHOIS and IDENTIFY commands has been changed to support multiple
5298 Client ID's per command. One can now search for multiple users
5299 in the network by sending only one WHOIS or IDENTIFY command.
5300 Changed the code and the protocol specifications.
5302 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5303 uses silc_server_command_whois_parse to parse the request. */
5305 * If normal server, do not parse the WHOIS and IDENTIFY requests
5306 before sending it to the router. Saves some time.
5308 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Fixed JOIN command on client library. Wrong number of arguments
5311 used to crash the client.
5313 * Added silc_server_channel_has_global function to check whether
5314 channel has global users or not.
5316 * Added silc_server_channel_has_local function to check whether channel
5317 has locally connected clients on the channel.
5319 * The silc_server_remove_from_one_channel now checks whether the
5320 channel has global users or not after given client was removed from
5321 the channel. It also checks whether the channel has local clients
5322 on the channel anymore. If it does not have then the channel entry
5323 is removed as it is not needed anymore.
5325 * The silc_server_notify now checks on JOIN notify whether the joining
5326 client is one of locally connected or global. If it is global then
5327 the channel has now global users on the channel and that is marked
5328 to the channel entry. Also, it now saves the global client to
5329 global list who is joining and JOINs it to the channel. This is
5330 for normal server, that is.
5332 Changed silc_server_send_notify_on_channel,
5333 silc_server_packet_relay_to_channel and
5334 silc_server_packet_send_to_channel check if we are normal server
5335 and client has router set (ie. global client) do not send the
5336 message to that client, as it is already routed to our router.
5338 * Implemented LEAVE notify type handling in silc_server_notify
5341 * Tested LEAVE command in router environment successfully. Tested
5342 with two routers, two servers and two clients.
5346 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5348 * Implemented SIGNOFF notify type handling in silc_server_notify
5351 * silc_server_remove_id now removes the client entry from all channels
5352 it has joined and thusly sends SIGNOFF notify type.
5354 * Rewrote the NAMES list generation in server by removing two excess
5355 loops. The lists are created now inside one loop.
5357 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * silc_server_remove_channel_user checks now also global list
5360 for channel and client.
5362 * silc_server_new_channel_user checks now both local and global
5363 list for channel and client. Fixed a bug in client id decoding.
5364 Used to decode wrong buffer.
5366 * silc_server_channel_message checks now both local and global
5367 list for channel entry.
5369 * Tested channel joining (hence JOIN) in router environment
5370 successfully. Tested with two routers, two servers and two
5373 * Tested channel message sending in router environment successfully.
5375 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Added silc_server_save_channel_key into server.[ch] to save the
5378 received channel key in Channel Key payload processing. It is
5379 also used in JOIN command reply handling.
5381 Equivalent function silc_client_save_channel_key added into
5382 client.[ch] into client library.
5384 * Changed JOIN command reply to send information whether the channel
5385 was created or not (is existing already) and the channel key
5386 payload. Changed protocol specs accordingly.
5388 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5389 the request was sent by ID and not by nickname. Crashed on
5392 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5395 now correctly save the received data.
5397 * silc_server_free_sock_user_data now notifies routers in the
5398 network about entities leaving the network.
5400 At the same time implemented functions silc_server_remove_id
5401 and silc_server_send_remove_id to receive and send REMOVE_ID
5402 packets. The packet is used to notify routers in the network
5403 about leaving entities. The ID removed will become invalid in
5406 * Added function silc_idlist_del_server into server. Removes and
5407 free's server entry from ID list.
5409 * silc_server_private_message function now checks, if we are router,
5410 that the destination ID really is valid ID, naturally.
5412 * In router when NEW_ID packet is received (for new client) the
5413 hash of the Client ID is saved in the ID Cache but the
5414 client->nickname is set to NULL, instead of putting the hash
5417 IDENTIFY command now also checks that client->nickname must be
5418 valid. If it is not if will request the data from the server who
5419 owns the client. Added new function
5420 silc_server_command_identify_check.
5422 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5423 to set the command to already allocated Command Payload.
5425 * Tested private message sending in router environment with two
5426 routers, two servers and two clients. Fixed minor bugs and now
5429 * Fixed segfault from client's NAMES command. Used to crash if
5432 * Forwarded packets must not be routed even if it is not destined
5433 to the receiver. Changed server code comply with this.
5435 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Added `require_reverse_mapping' boolean value to ServerParams
5438 structure. If TRUE (not default) the server will require that
5439 the connecting host has fully qualified domain name.
5441 If the reverse mapping is not required and hostname could not be
5442 found the IP address is used as hostname.
5444 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Implemented version string checking to both client and server.
5447 The check is incomplete currently due to the abnormal version
5448 strings used in development version of SILC.
5450 * Changed all command functions in server to use the new
5453 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Changed char *data to unsigned char *data in ID Cache system to
5456 support binary data as ID Cache data. Changed code to support
5457 binary data in lib/silccore/idcache.c.
5459 * Renamed silc_server_packet_relay_command_reply to
5460 silc_server_command_reply as it is normal packet receiving
5461 function. Rewrote the function to accept command replys for
5462 servers and not only for clients.
5464 * Mark remote router always as registered server if we are connecting
5465 to it. Otherwise, commands sent by the router to us are ignored.
5467 * All ID List find routines now returns the ID Cache Entry pointer
5468 as well if requested.
5470 * WHOIS command works now in router environment, tested with two
5471 routers, two servers and two clients.
5473 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5474 in router environment (as it is almost equivalent to WHOIS) but
5475 hasn't been tested thoroughly. Added new functions:
5477 silc_server_command_identify_parse
5478 silc_server_command_identify_send_reply
5479 silc_server_command_identify_from_client
5480 silc_server_command_identify_from_server
5482 * Disabled route cache adding because adding two different ID's with
5483 same IP replaces the old cache entry thus giving wrong route.
5484 The entry->router->connection is always the fastest route anyway
5485 so route cache may not be needed. Of course, new routes maybe
5486 established after receiving the ID when the entry->router->connection
5487 might not be anymore the most optimal.
5489 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Add route cache for received ID for fast routing.
5493 * Added silc_server_packet_route to route received packet on router
5494 that is not destined to us.
5496 * Renamed silc_server_get_route to silc_server_route_get.
5498 * Added id_string and id_string_len fields into SilcServer to
5499 include encoded ServerID for fast comparing without excess
5500 encoding of the ID's.
5502 * Cleaned up WHOIS command on server side. Added following static
5505 silc_server_command_whois_parse
5506 silc_server_command_whois_check
5507 silc_server_command_whois_send_reply
5508 silc_server_command_whois_from_client
5509 silc_server_command_whois_from_server
5511 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5512 arguments in command replies. All command functions should be
5513 updated to use this macro.
5515 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Minor typo fixes on command reply handling on server.
5519 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Added silc_server_command_add_to_channel internal routine to add
5522 the client to the channel after router has created the channel and
5523 sent command reply to the server.
5525 * Added generic silc_server_send_command to send any command from
5528 * Use static buffer with ID rendering instead of duplicating data.
5530 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Fixed a channel user mode bug when joining to a channel server gave
5533 everybody channel founder rights, oops.
5535 * We mark ourselves as the router of the incoming server connection
5536 if we are router ourselves. This way we can check in some packet
5537 sending functions whether it is locally connected server. For
5538 incoming router connections we put NULL.
5540 * For router sending packets locally means now always sending the
5541 packet cell wide; to local clients and local servers. For normal
5542 server sending packet locally means sending it to only local
5545 * Fixed the JOIN command to really work in router environment. If the
5546 channel is created it is always created by the router. Router is
5547 also responsible of making the initial joining to the channel,
5548 sending JOIN notify to the sending server and distributing
5549 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5550 does not exist server doesn't do anything else but forward the
5551 command to the router which performs everything.
5553 * Added silc_server_send_channel_key function to send the Channel Key
5556 * Added silc_server_create_channel_key to create new channel key. The
5557 channel key is now re-generated everytime someone joins or leaves
5558 a channel, as protocol dictates. Note: channel->key_len is the
5561 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5564 packet_receive.[ch] to separate packet sending and receiving
5565 routines. The server.[ch] now includes everything else including
5566 actual packet processing (writing and reading data) and other
5569 Renamed silc_server_private_message_send_internal to
5570 silc_server_send_private_message. The routine is still though
5571 used only to relay private messages as server does not send
5572 private messages itself.
5574 Renamed silc_server_new_channel to silc_server_create_new_channel
5575 and added new function sicl_server_new_channel that handles the
5576 incoming New Channel packet. Added also new sending function
5577 silc_server_send_new_channel to send New Channel Payload.
5579 * Added new function silc_server_notify to process incoming notify
5580 packet to the server/router. Server may then relay the notify
5581 to clients if needed.
5583 * Added new function silc_server_new_channel_user to process incoming
5584 New Channel User packet. Router will redistribute the packet and
5585 send JOIN notify to its local clients and locally connected servers
5586 if needed. Normal server will send JOIN notify to its local client
5587 on same channel when received this packet. Added also corresponding
5588 sending function silc_server_send_new_channel_user to sent the
5591 * Added boolean route argument to send_notif_to_channel and
5592 packet_send_to_channel functions to attempt to route the packet
5593 if it is TRUE and send only locally if it is FALSE.
5595 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * silc_server_replace_id now broadcasts the received replace ID
5598 packet if it is not broadcast packet already. The router must
5599 broadcast to inform other routers about changed ID.
5601 * Added backpointer to server's router into SilcServer context in
5602 silcd/server_internal.h.
5604 * Fixed silc_server_packet_broadcast to send correct broadcast
5607 * The channel key is now distributed to the local client as soon
5608 as it is received from the router (in router environment) so that
5609 no other packet may be sent for the channel until client has
5612 * silc_server_remove_channel_user now broadcasts the received
5613 Remove Channel User packet if it is not broadcast packet already.
5614 The router must broadcast to inform other routers about removed
5617 * Added users field into SilcPacketContext that is a reference count
5618 of the context. One can increase the reference count by calling
5619 silc_packet_context_dup which is now changed to just increase the
5620 reference count instead of duplicating the data. The reference
5621 count is decresed by calling silc_packet_context_free that will
5622 free the data after the reference count hits zero.
5624 For now on the packet context and everything allocated into it
5625 (including the raw packet from network) must be freed by calling
5626 the new silc_packet_context_free function. Added also new function
5627 silc_packet_context_alloc that must be used now to allocate the
5628 context. This also means that if a routine is asynchronous from
5629 silc_[client/server]_packet_parse_type the packet context must
5630 be duplicated by calling silc_packet_context_dup. Otherwise it
5631 gets free'd after silc_[client/server]_packet_parse_type returns.
5632 Also, one must remember that if packet is duplicated then its
5633 reference count must be decresed by calling the free function as
5634 many times as it was duplicated.
5636 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5637 from both client and server.
5639 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Made joining to a channel working in router environment.
5643 * Cleaned up JOIN command on server side and create function
5644 silc_server_command_join_channel internal routine to make the
5647 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Changed silc_command_pending list to SilcDList. Also, added
5650 `ident' field to SilcServerCommandPending structure to identify
5651 the reply and to call correct callback.
5653 Added silc_server_command_pending_check function to replace the
5654 corresnponding macro. The silc_command_pending list is not
5657 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5658 to set identifier to previously allocated Command Payload. It
5659 is used to set identifier for command when resending Command
5662 * Added silc_command_payload_encode_payload to encode Command
5663 Payload buffer from SilcCommandPayload structure.
5665 * Added silc_argument_payload_encode_payload to encode Argument
5666 payload buffer from SilcArgumentPayload structure.
5668 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Changed WHOIS command to support router connection on server side.
5671 The whois request is always sent to router unless the server is
5672 standalone server. After server has received the reply from the
5673 router will it send the reply to the client.
5675 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5676 broadcast received broadcast packet. The function is used only
5677 by router. The broadcast packet is always sent to the router's
5680 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5681 render given ID to printable string, for log files for example.
5683 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Made basic router to router connections working. At least they
5686 can now connect to each other but nothing really works the way
5687 they are supposed - yet.
5689 * Added new initiator token to RouterConnection configuration
5690 file in silcd/serverconfig.[ch]. It is used to tell whether we
5691 are the initiator to the remote router or whether we'll expect
5692 the other end to connect.
5694 * Moved registering of listener task to silc_server_init, hence
5695 the server starts listenning as soon as it is run, even if it
5696 does not have connections to other routers. Let's see how well
5699 * Changed default connection retry timeouts for more suitable in
5702 * Removed cipher and such arguments from silc_idlist_add_client
5703 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5704 Added new function silc_idlist_add_data to add the keys and stuff
5707 * Added SilcIDListData structure and added it to SilcClientEntry
5708 and SilcServerEntry as their first field in the structure. This
5709 way we can explicitly cast the ID entries to the SilcIDListData
5710 structure and get common data for the entries. In past, we had
5711 to first check what type of connection it is and then cast it to
5712 correct ID entry type. Now, we can directly cast the opaque
5713 pointer to the SilcIDListData (no matter what ID entry it actually
5714 is) and get the data needed.
5716 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5719 in some circumstances even if threre were timeout tasks, though not
5720 IO tasks, but tasks anyway. Now fixed.
5722 * Defined SilcServerConnection structure to hold connection specific
5723 stuff about directly connected servers and routers. The definition
5724 is currently in silcd/server_internal.h. I thought about having
5725 a bit more important role fro this struct but for now it is used
5726 only when connecting to other server (or router actually).
5728 * Added connecting retry support in server when connecting to
5729 router(s). The retry feature implement exponential backoff
5730 algorithm. Also, added SilcServerParams structure to hold default
5731 parameters for server. For now, it include these retry settings
5732 and are hard coded. After server is moded to be as Silc Server
5733 Library this structure will be more important.
5735 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Changed client librarys channel->clients table to SilcList and
5738 changed code accordingly.
5740 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Changed client's channel table to SilcList and changed code
5743 accordingly. Also changed SilcChannelClientEntry to include back-
5744 pointer to the channel so that client entry can use that structure
5745 as list as well and we have fast cross-reference to the channel.
5746 This change dramatically decreased the complexity of channel
5747 handling with client entry and vice versa (removed one extra
5748 loop when searching for channel entry from many functions).
5750 * Changed server->sim from table to SilcDList and changed code
5753 * NAMES command can now be used from user interface. It will show
5754 the user list on the channel, neatly.
5756 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5757 Code now saves realname of the user if it becomes available.
5759 * Renamed configure.in to configure.in.pre and made ./prepare
5760 script to automatically add correct version string to
5761 configure.in which it creates from configure.in.pre.
5763 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * NAMES command reply now shows users mode with the nickname when
5768 * Moved silc_client_ch[u]mode[_char] functions from
5769 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5770 place sucks, they are utility functions and should be in some
5773 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5775 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5778 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Added TRQ (efficient deque and list library) into lib/trq. This is
5783 a very good list library that is currently used in the SILC. Defined
5784 SilcList API over the library because I didn't like the API very
5785 much. See lib/trq/silclist.h for the API and examples of how to
5786 use the API. Fixed various places in the code to use the new
5787 SilcList API. The SilcList is meant for lists that has a structure
5788 already defined as a list. It is not suitable to add just some
5789 context to the list (in TRQ, the context is the list actually).
5791 So, I defined SilcDList that can be used for the purpose where
5792 predefined list structure does not exit. This can be used as
5793 such list. Now some context just can be added to the SilcDList.
5794 Currently this list is not used in the SILC just yet, though there
5795 are a lot places where this can replace dynamically allocated
5796 tables and I will fix these places, later, to use SilcDList.
5797 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5798 and use TRQ internally).
5800 Also fixed some annoying warning messages that the original TRQ
5801 code generated. Also minor changes to TRQ's Makefile.in.
5803 * Added support for querying by Client ID to both WHOIS and
5804 IDENTIFY commands into server, as required by the protocol.
5806 * Removed method function pointers from SilcBuffer structure. They
5807 weren't used to anything and just increased the context size for
5808 no good reason. This change also made silc_buffer_alloc and
5809 silc_buffer_free functions inline functions.
5811 * Disabled command flooding detection support until it's fixed so
5812 that it accepts commands in but does not execute them more than once
5815 * Added silc_net_localhost(), to return local hostname, into
5816 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5817 that must be initialized before calling silc_client_init.
5819 * Added new function: silc_server_send_notify_on_channels to send
5820 notify messages to all channels client has joined. It is assured
5821 that the message is sent only once per client.
5823 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5824 lib/silcutil/silcutil.[ch] as silc_format function. The new
5825 function is generic and is used by server as well, not only by
5826 the logging routines.
5828 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5829 the provided version string was not acceptable. Added new function:
5830 silc_ske_check_version into lib/silcske/silcske.h. The function
5831 must be implemented by the application (client or server) and it
5832 does not reside in the SKE library. The function checks the version
5833 string remote end sent.
5835 * Added back pointers (to opaque context and to SilcSocketConnection)
5836 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5838 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5839 duplicate packet context structure.
5841 * Changed `notify' client operation to send same arguments as client
5842 receives from server except for ID's. ID's are mapped to correct
5843 ID entry and that is returned. Also, if channel entry is not sent
5844 by server but the notify is for channel the channel entry is sent
5845 to application (otherwise application doesn't know that it is for
5846 channel (library gets it from packet's Destination ID)).
5848 * Added silc_client_remove_from_channels into client library to
5849 remove a client from all channels it has joined to. Used when
5850 received SIGNOFF notify from server. Added also new function
5851 silc_client_replace_from_channels to replace old ID entry with
5852 new ID entry on all channels. Used when received NICK_CHANGE
5855 * Fixed ID Cache list handling in silc_idlist_get_client in
5856 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5857 to get (or query) client by ID.
5859 * Updated TODO list.
5861 * Added connection authentication status message defined by the
5862 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5863 support for these into the code in client and server side.
5865 * Added generic function silc_client_send_command to send any command
5866 with variable argument list. Application should use this function
5867 to send commands if the command functions provided by the library
5868 does not suite for the application's user interface needs.
5870 * Added new `failure' client operation. Application is notified about
5871 received failure packet if client is executing a protocol. In this
5872 case the protocol's execution has failed.
5874 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5875 is required by the protocol.
5877 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5878 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5881 * Added status flag to SilcSKE object to indicate realtime status
5882 of the SKE protocol.
5884 * Application receives now exactly same command reply arguments as
5885 the library receives from server. However, if ID is received the
5886 corresponding ID entry is returned to the application (eg. Client
5887 ID is mapped to correct SilcClientEntry entry and that is returned).
5888 Changed command_reply client operation due to this change.
5890 * Changed all ID's in commands and in command replys as ID Payloads.
5891 Change affected both client and server side codes.
5893 All ID's sent in SILC network (with execption of ID's in SILC
5894 Packet header) are sent in ID Payload to support variable length
5897 * Server now notifies nick changes and notifies all clients on
5898 the channels about the new nickname (about the new Client ID,
5901 * Implemented CMODE command to change channel modes. Supports all
5902 channel modes defined by the protocol specs except ban and invite
5903 lists. (Also, private channel key mode is supported but support for
5904 setting private channel key in client is missing, thus, this mode
5905 has no effect on client side (except that server requires that the
5906 client uses private channel key and normal channel traffic does not
5909 Also, invite mode works per se, but INVITE command does not work
5910 yet correctly, so you can set channel as invite only channel but
5911 inviting clients to the channel does not work (it is yet to be
5912 thought what's the best way to do it).
5914 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5915 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5916 Implemented CUMODE command to change user's mode on the channel.
5917 Supports all modes defined by the protocol specs.
5919 * Added NAMES command reply to return users modes on the channel.
5921 * Removed unnecessary and slow ciphers from lib/silccrypt.
5923 * Set SO_KEEPALIVE option to connection sockets by default.
5925 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5927 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5928 redefined the Notify Payload into protocol specs.
5930 * Added silc_id_payload_parse_id to get ID directly from raw
5933 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5936 accept searching by Client ID as well.
5938 * Added support for LEAVE and SIGNOFF notify types in client library.
5940 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5941 to parse ID Payload from raw data.
5943 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Added flags parameter into silc_ske_assemble_security_properties
5946 function in lib/silcske/silcske.[ch].
5948 * Changed notify client operation to fit better for notify messages
5949 sent by server. The notify payload received from server is now
5950 passed to the application (after parsing it to SilcNotifyPayload).
5951 It is application's responsibility to retrieve the arguments
5952 from the payload and show the message the way it wants. The message
5953 sent by server is implementation specific.
5955 * Changed public keys to comply with the protocol specification.
5956 Old public keys are not supported anymore and are not compatible.
5958 * Removed nickname from Channel Payload as the latest draft removed
5959 it. The client must resolve the nickname from the NAMES command
5960 reply received when it joined the channel.
5962 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5964 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Fixed some errors in protocol specification drafts.
5968 * Created lib/silccore/silcnotify.c to implement Notify Payload
5969 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5970 generic payloads described by protocol specifications. The file
5971 includes implementations for ID Payload and Argument Payload.
5973 * Changed Command Payload implementation to use the new Argument
5974 Payload. Changed command_xxxx_payload to command_payload_xxxx
5975 to comply with SILC coding conventions.
5977 * Added suppport for Argument Payload handling in Notify Payload
5978 implementation as protocol requires it. Added the new support
5979 into server and client lib as well.
5981 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added support for multiple nicknames on same channel. [n] is
5984 added locally to the nickname if there are more than one same
5985 nicknames on the channel.
5987 * Server now sends all nicknames that matched WHOIS request.
5988 Client also shows the list received from server.
5990 * Added TOPIC command to client side. User can now set and show
5991 current topic on channel.
5993 * Added MOTD command to client and server. Also, server sends the
5994 motd when client connects to the server.
5996 * Changed version strings to comply ISO 8601.
5998 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Fixed protocol error handling in client library. It should now
6001 cope even if the SKE fails for some reason.
6003 * Made new protocol specification drafts for submitting to IETF.
6005 * Implemented TOPIC command to server in silcd/command.c.
6007 * Added two new notify types into lib/silccore/silcnotify.h:
6008 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6009 notify nickname change and topic setting/change on a channel.
6011 * API change of command_reply operation in client library. The
6012 application gets now the status type received from server as well.
6014 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6018 * Cras fixed and optimized the packet handling even further and
6019 it should work now. Minor change to the prototype of function
6020 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6022 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Added new function into lib/silcutil/silcschedule.[ch]:
6025 silc_schedule_with_fd to select() a specified fd. The function
6026 returns after timeout expires or data arrives or goes. The
6027 function is used by packet routines to wait that all data is
6028 received from network.
6030 * Fixed data reading from network in lib/silccore/silcpacket.c.
6031 The code now assures that all data is read from the fd and then
6032 continues packet processing. This was a bug fix since the code
6033 used to drop some data in some circumstances.
6035 * Added new function into lib/silcclient/client.[ch]:
6036 silc_client_start_key_exchange to start key exchange after
6037 connection has been established to server. The code internally
6038 now uses this funtion but its main purpose was to provide it
6039 for applications that perform their own connecting. After
6040 application has created a connection it merely calls this
6041 function to start the key exchange between client and server.
6042 The library takes care of everything else after that.
6044 Updated also lib/silcclient/README to explain the usage of
6047 * Do not send to application information that connection has
6048 been established. Application gets notified it by connect
6051 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Applied cras's patch to add silc_schedule_one function. The
6054 function runs scheduler once and returns.
6056 * Fixed the scheduler after cras messed it up. The timeout
6057 handling works now as it's supposed to work.
6059 * Added into lib/silccore/ silcnotify.h to include notify
6060 message types support. Changed silc_server_send_notify*
6061 functions, in server.[ch], to support those new notify types.
6062 Added the support for the notify types into client library,
6063 as well. Added new notify client operation into ops.h in
6066 * Changed silc_server_packet_send_to_channel to send normal
6067 packets instead of just channel message packets. The function
6068 is now used to send the notify packets to channels. It is not
6069 used to send channel message packets anymore, as server never
6072 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6073 va_arg()s as it seems to require it nowadays. I guess, if SILC
6074 is compiled with older va_arg() the new code should work anyway.
6076 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Splitted core library. Core library (lib/silccore) includes
6079 now only SILC protocol specific core (and common) components.
6080 Created new utility library (lib/silcutil) that includes more
6081 generic purpose stuff. The stuff for util library was taken
6082 from the old core library. This was minor and easy split.
6084 * Created SILC Client Library (lib/silcclient) that includes
6085 implementation of the SILC client without user interface. This
6086 was major move from silc/ directory. The code has been changed
6087 so that it is transparent towards the user interface. The
6088 silc/ directory includes now the same user interface as before
6089 and it uses the new client library. Read lib/silcclient/README.
6090 Basicly, the client library performs everything else related
6091 to SILC except user interface handling. Also, configuration
6092 files are considered to be part of user interface and library
6093 does not handle them.
6095 This change also changed a lot of structures, function naming etc.
6096 Most important change was that SilcClientWindow object was
6097 renamed to SilcClientConnection in the client library. Created
6098 also new file lib/silcclient/ops.h. Also added new files
6099 silc/local_command.[ch] and silc/client_ops.[ch].
6101 All these changes were made to make it easier for user interface
6102 designers to create what ever user interface for the SILC client
6105 It is also expected that the server will be moved to lib
6106 directory as well and SILC Server Library will be created;
6107 sometimes in the future.
6109 * Removed Local commands from lib/silccore/silccommand.h as
6110 they are application specific and new client library does not
6111 handle any of those anymore.
6113 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6114 old client implementation in silc/.
6116 * Added support for callback functions in SILC_LOG_* macros.
6117 Application can now set its own callbacks that will be called
6118 instead of using the default functions that will always print
6119 the debug messages to stderr (or stdout). Also, debugging can
6120 now be disabled by setting silc_debug to FALSE and re-enabled by
6121 setting it to TRUE. Note, that logging will still work even
6122 if debugging is disabled.
6124 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6125 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6126 silc_log_reset_debug_callbacks.
6128 * To enable debugging in silc client one must give now -d
6129 option on command line.
6131 * Changed silc_schedule_init to automatically allocate task queues
6132 if they are not allocated before calling it.
6134 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Added GMP 3.1 into math library.
6138 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6141 a channel in SILC network. The packet is used by servers and
6142 routers to notify other routers that user has left a channel.
6143 This little feature was missing until now. Added the feature
6144 to protocol specification as well.
6146 Added functions: silc_server_send_remove_channel_user and
6147 silc_server_remove_channel_user into server.[ch].
6149 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6150 lib/silccore/silcpacket.h. However, they are not implemented
6153 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Fixed joining to a channel and sending channel messages
6156 between server and router. The channel message sending should
6157 now work inside a cell.
6159 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Fixed the private message sending between server and router.
6162 The private message sending should now work inside a cell.
6164 * Added silc_server_replace_id into server.[ch] to replace
6165 existing ID in the SILC network.
6167 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6168 and silc_idlist_replace_server_id into idlist.[ch] in server.
6170 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Fixed the server to server connections. Server can again now
6173 connect to router. Router to router connections probably does
6176 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Added dynamic protocol registering support. Now protocols can
6179 registered and unregistered on the fly. Patch by cras.
6181 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Added lib/contrib directory to hold routines that some platforms
6184 don't have but are needed by SILC.
6186 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6187 into lin/contrib to provide getopt() and getopt_long() for
6188 those who don't have it.
6190 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Added AWAY command to client. When away message is set and
6193 client receives a private message packet the client automatically
6194 replies to the sender with the away message.
6196 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6197 bug seemed to be the cause of recent problems when compiling
6200 * Added version detection support to SKE protocol specification
6201 and added the new changes to the SKE implementation as well.
6202 There were other minor changes in the SKE protocol as well.
6204 Many changes in lib/silcske/silcske.[ch] and in
6205 lib/silcske/payload.[ch].
6207 * Added ^U functionality, clear input line. Patch from cras.
6209 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Mainly small bugfixes on core library. Fixed some debugging
6212 logging and buffer overflow in silclog.c.
6214 * Updated config.sub and config.guess on the distribution tree.
6216 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Added command lagging support in server. Client may execute
6219 commands now only once in two seconds.
6221 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Optimized packet reception. MAC computation and checking is now
6224 also more optimized. A lot previously duplicated code is now
6225 used as generic by both client and server.
6227 * Fixed key pair generation in clientutil.c
6229 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Added into lib/silccore/silcbufutil.[ch] new function;
6232 silc_buffer_realloc.
6234 * Moved generic packet sending/encryption functions to
6235 lib/silccore/silcpacket.[ch] from client and server. Some
6236 rewriting of the functions.
6238 * Moved all generic packet reception/decryption functions to
6239 lib/silccore/silcpacket.[ch] from client and server. The
6240 packet processing is now much cleaner in both client and server.
6241 These were major changes in both client and server.
6243 * Created many common functions in server to do packet sending.
6244 Previously code were duplicated a lot, this has been removed
6247 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Rewrote major parts of the ID cache system. Don't know
6250 whether it is better now or not but at least the API is more
6253 * Major rewrite on ID cache stuff on client because of the ID
6254 cache API changes. Added idlist.c to client.
6256 * Also major rewrite on ID cache stuff on server as well.
6257 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6258 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6259 in hand, instead they are all put into the ID cache system now.
6260 All server_idlist_* routines uses ID cache now instead of
6261 traversing its own lists (those lists does not exist anymore).
6262 SilcIDList though still exists. Also, SilcXXXEntry's are
6265 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Finally made the SKE implementation compliant to the protocol
6268 specification. All mp integers are now binary encoded as
6269 opposed being HEX encoded.
6271 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6274 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6275 functions: silc_[encode/decode]_pem. Also added function
6276 silc_encode_pem_file to PEM encode with newlines ('\n') for
6279 * SILC public keys are now encoded either PEM or binary. Same
6280 option is for private keys as well. By default private keys
6281 are binary encoded and public keys PEM encoded. Silly HEX
6282 encoding were removed.
6284 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6285 function to create fingerprints.
6287 * Fixed a bug in SHA1; does not change the original data anymore.
6289 * Partly implemented INFO command on client and server side.
6290 Fixed CLEAR command. Changes to SERVER command; show current
6291 server(s) when giving command without arguments. Added
6292 VERSION command to client.
6294 * Added check to server that unregistered connections cannot
6295 execute commands (unless it is specificly allowed).
6297 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Fixed screen refresh.
6301 * Fixed channel joining bug from client. On some circumstances
6302 client tried to join to a channel it had already joined.
6304 * Added public key verification process into client's protocol.c.
6305 The client now verifies the public key from user and saves
6306 it into ~./silc/serverkeys/ directory.
6308 Added into: clientutil.[ch]: silc_client_verify_server_key.
6310 * Changed SKE protocol's silc_ske_initiator_finish function
6311 to accept callback function that verifies the received public
6312 key. Removed old silc_ske_verify_public_key function.
6314 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6317 silc_pkcs_private_key[_data]_set.
6319 * Made the password and public authentication more cleaner in
6320 server's protocol.c.
6322 * Removed historic and obsolete protocol `channel_auth' from
6323 both client and server.
6325 * Removed wrong way of sending command status messages from
6326 server to client in server's command.c. The old way violated
6327 protocol specification.
6329 Changes to silccore/silccommand.[ch]: removed
6330 silc_command_encode_status_payload -> not needed anymore,
6331 changed silc_command_encode_payload_va to accept extra
6332 argument on variable argument list. The argument type must
6333 now be provided to the function. Also, added new function:
6334 silc_command_encode_reply_payload_va which is same as
6335 normal command_encode_payload_va except command status type
6336 is provided as extra argument.
6338 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Added ~./silc directory handling. The directory includes the
6341 public and private keys for the client.
6343 Added silc_client_check_silc_dir, silc_client_create_identifier
6344 and silc_client_load_keys.
6346 * Implemented SILC protocol compliant public key. Added public
6347 and private key saving to and loading from files.
6349 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6350 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6351 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6352 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6353 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6355 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6356 silc_pkcs_load_[public/private]_key.
6358 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Added silc_server_get_route (route.[ch]) to get connection
6361 data for the fastest route for given ID.
6363 * Implemented INVITE command on client and server. The command
6364 were re-defined in the SILC Protocol Specification and the
6365 implementation now complies with the specification.
6367 * Implemented PING command on client and server.
6369 * Implemented NAMES command on client and server. The server side
6370 supports currently only normal server not router server yet.
6371 Some changes to NAMES definition in SILC protocol specification.
6373 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Implemented LEAVE command on client and server.
6377 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6378 again. This change was made to the protocol as well. Server
6379 should not violate the protocol specification anymore.
6381 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6384 was tested. SOCKS4 was not but should work anyway.
