4 Updated specs and implemented it. Affected file silcd/command.c,
5 silcd/packet_send.c and silcd/packet_receive.c.
7 * Implemented the <founder auth> payload handling in the JOIN
8 command. If provided all conditions for channel joining
9 except requirement to provide correct passphrase can be
10 overrided by the channel founder. Updated the protocol specs.
11 Affected file silcd/command.c.
13 Added support for founder auth in JOIN command in client
14 library. Fixed the parsing of the JOIN command now to support
15 all options as they should be. The affected file is
16 lib/silcclient/command.c.
18 * Optimized the WHOIS and IDENTIFY commands to send the request
19 to router only if it includes nicknames or other names. If

21 routing. Affected file is silcd/command.c.
23 * Added channels topic announcements. Affected file is
24 silcd/packet_receive.c and silcd/server.c.
26 * Fixed the silc_server_send_notify_topic_set to really destine
27 the packet to channel. Affected file silcd/packet_send.c.

42 lib/silccrypt/silcpkcs.c
43 lib/silccore/silccommand.c
44 lib/silccore/silcidcache.c
49 * ROBOdoc documented the lib/silcske/groups.h file and a
50 bit changed the interface for better.
52 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
54 * Update the client entry context in the ID cache after
55 nick change. Affected file lib/silcclient/command.c.
56 Fixes the CUMODE command when regaining founder privileges,
57 and a little WHOIS problem.
59 * Fixed silc_net_gethostbyname to correctly call the
60 inet_ntop. Affected file lib/silcutil/silcnet.c.
62 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
64 * Added IPv6 support checking to the configure.in.pre, added
65 also --enable-ipv6 option to override the check. Affected
66 file configure.in.pre.

92 * Fixed LIST command reply sending in server. Affected file
95 * Server now sends the kicker's client ID in the KICK notify
96 to the kicked client. Affected file silcd/command.c.
98 * The client library now parses the kickers client ID and
99 UI displays it. Affected files lib/silcclient/client_notify.c
100 and irssi/src/silc/core/silc-channels.c, module-formats.c.
102 * Made all payload parsing function prototypes consistent.
103 They all take now const unsigned char * and uint32 pair as
104 the payload data instead of SilcBuffer. Changes all around
105 the source tree. Other unsigned char* -> const unsigned char*
106 changes around the tree as well.
108 * Optimized SFTP client and server packet sending not to
109 allocate new buffer for each packet but to recycle the
110 first allocated buffer. Affected files are
111 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
113 * Optimized the SFTP client to use SilcList instead of
114 SilcDList for requests, because it is faster. Affected file
115 is lib/silcsftp/sftp_client.c.
117 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
118 into lib/silccore/silcid.[ch].
120 Renamed silcpayload.[ch] into silcargument.[ch].
122 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
124 * If client entry is deleted with active key agreement
125 session, abort the session.
127 The silc_client_abort_key_agreement now calls the completion
128 callback with new SILC_KEY_AGREEMENT_ABORTED status.
130 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
133 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
135 * Don't use __restrict in older GCC's. Affected file is
136 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
138 * silc_net_localhost now attempts to reverse lookup the
139 IP/hostname. Affected file lib/silcutil/silcnet.c.
141 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
142 command. It can be used to gain founder privileges at
143 the same time when joining the channel.
145 Defined that the SILC_NOTIFY_TYPE_KICKED send the
146 kicker's client ID as well. Updated protocol specs.
148 Defined that the server must send SILC_COMMAND_IDENTIFY
149 command reply with error status to client who sent
150 private message with invalid client ID.
152 Updated the protocol specification.
154 * Added silc_server_send_command_reply to send any
155 command reply. Affected file silcd/packet_send.[ch].
157 * Added silc_id_payload_encode_data to encode ID payload
158 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
160 * The server now send IDENTIFY command reply with error
161 status if client ID in private message is invalid. Affected
162 file silcd/packet_receive.c.
164 * Save the server key file with server's IP address in
165 the filename instead of hostname. The affected file is
166 irssi/src/silc/core/client_ops.c.
168 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
170 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
173 * Added libtool support for compiling shared objects in
174 lib/silcsim. Affected file configure.in.pre and
175 lib/silcsim/Makefile.am. Original patch by cras.
177 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Pid file configuration, and server's config file fixes
180 patch by toma. Updated CREDITS file.
182 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Fixed silc_client_channel_message to not try to decrypt
185 the message twice if it resolved the destination client
186 information. This could cause of dropping one channel
187 message. Affected file lib/silcclient/client_channel.c.
189 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
191 * Added silc_client_run_one into lib/silcclient/silcapi.h and
192 lib/silcclient/client.c. This function is used when the SILC
193 Client is run under some other scheduler, or event loop or
194 main loop. On GUI applications, for example this may be
195 desired to used to run the client under the GUI application's
196 main loop. Typically the GUI application would register an
197 idle task that calls this function multiple times in a second
198 to quickly process the SILC specific data.
200 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
202 * Fixed silc_server_drop() for dropping the supplementary
203 groups as well, this could cause a security hole on some
206 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
208 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

212 to run server on foreground. A patch by debolaz.
213 Affected files silcd/server.c, silcd/silcd.c.
215 * Fixed MOTD to return the MOTD file server name. Affected
216 file silcd/command.c.
218 * Added INFO command reply handling to the Irssi SILC Client.
219 Affected file irssi/src/silc/core/client_ops.c.
221 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>

224 the dynamic list. Fixes a crash. Affected file is
225 lib/silccore/silcidcache.c.
227 * Fixed the LIST command reply to really call LIST command's
228 pending callbacks. Affected file silcd/command_reply.c.
230 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
232 * Update conn->local_entry->nickname after giving NICK
233 command. Affected file lib/silcclient/command.c.
235 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
237 * Added the [pid] option to the silcd configuration file
239 Affected files: serverconfig.[ch] and silcd.c

243 * Save fingerprint in WHOIS command reply in server.
244 Affected file silcd/command_reply.c.
246 * Fixed NICK commands pending callback registration.
247 Affected file lib/silcclient/command.c.
249 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
251 * Use ++server->cmd_ident when sending commands in server,
252 instead of random number. Affected file silcd/command.c.
254 * Fixed GETKEY command reply to call actually GETKEY pending
255 command callbacks. Affected file silcd/command_reply.c.
257 * A bit stricter check for nicknames. Check for same nickname
258 in NICK command also. Affected file silcd/command.c.
260 * Do not call INFO command everytime client ID changes, only
261 during first connecting. Affected file lib/silcclient/client.c.
263 * Set the new nickname only after successful command reply for
264 NICK command is returned by server. Affected file
265 lib/silcclient/command.c.
267 * Remove nicknames from nicklist during server_signoff notify.
268 Should fix /NAMES bit more. The affected file is
269 irssi/src/silc/core/silc-channels.c.
271 * Added `fingerprint' field to the SilcIDListData in the
272 silcd/idlist.h to hold the fingerprint of the client's
275 Send the fingerprint of the client's public key in WHOIS
278 Affected files silcd/command.c, and silcd/idlist.[ch].
280 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
281 create fingerprint from given data.
283 * Show the fingerprint of the client's public key in WHOIS.
284 Affected files irssi/src/module-formats.[ch] and
285 irssi/src/silc/core/client_ops.c.
287 * Format the multiple same nicknames also during JOIN and
288 NICK_CHANGE notifys. Affected file is
289 lib/silcclient/client_notify.c.
291 * Do not print error on screen for invalid private message
292 payload since it can come if someone is sending private
293 messages with wrong key. Affected file
294 lib/silccore/silcprivate.c.
296 * Fixed multiple concurrent /PING crash. Affected file
297 lib/silcclient/command.c.
299 * Changed the wrong ID encoding. All IP addresses must be
300 in MSB first order in encoded format. They were encoded
301 wrong and was in LSB format. Affected files are
302 silcd/serverid.c, lib/silcutil/silcutil.c.
304 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
306 * Call the `connect' client operation through the scheduler
307 in case of error. Affected file lib/silcclient/client.c.
309 * Call the `failure' client operation even if the error
310 occurred locally during a protocol. Affected file is
311 lib/silcclient/protocol.c.
313 * Added support of sending LIST command to router from normal
314 server. This way normal server can get list of all channels
315 in the network too. Fixed the channel list sending in the
316 server too. Affected files are silcd/command.c, and
317 silcd/command_reply.[ch].
319 * Added silc_server_update_channels_by_server and
320 silc_server_remove_channels_by_server. They are used during
321 disconnection of primary router and in backup router protocol.
322 Affected file silcd/server_util.[ch], silcd/server.c and
323 silcd/server_backup.c.
325 * Fixed channel adding to global list in IDENTIFY command
326 reply in server. Affected file silcd/command_reply.c.
328 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
330 * If the incoming packet type is REKEY or REKEY_DONE process
331 that packet always synchronously. Fixes yet another MAC
332 failed error on slow (dialup) connections. Affected file
333 lib/silcclient/client.c and silcd/server.c.
335 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Call check_version SKE callback for initiator too. Affected
338 file lib/silcske/silcske.c.
340 * Implemented fix for security hole found in the SKE that was
341 fixed in the specification few days back; the initiator's
342 public key is now added to the HASH value computation.
343 Added backwards support for the old way of doing it too, for
344 old clients and old servers. Affected file is
345 lib/silcske/silcske.c.
347 * Enabled mutual authentication by default in SKE. If initiator
348 is not providing mutual authentication the responder will
349 force it. This will provide the proof of posession of the
350 private key for responder. The affected files are
351 lib/silcclient/protocol.c and silcd/protocol.c.
353 * Do not cache anymore the server's public key during SKE.
354 We do mutual authentication so the proof of posession of
355 private key is done, and if the server is authenticated in
356 conn auth protocol with public key we must have the public
357 key already. Affected file silcd/protocol.c.
359 * Added new global debug variable: silc_debug_hexdump. If
360 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
361 file lib/silcutil/silclog.[ch].
363 * Fixed compilation warning due to char * -> const char *.
364 Affected files lib/silcutil/silcnet.h, and
365 lib/silccore/silcauth.[ch].
367 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Fixed CMODE command when new channel key was created. If
370 the creation failed the old key was removed. Next time giving
371 same command would crash the server since the old key was
372 freed already. Affected file silcd/command.c.
374 * Fixed the silc_server_announce_get_channels to not crash
375 on reconnect. Affected file silcd/server.c.
377 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
379 * Added silc_log_set_debug_string function to set a regex
380 string to match for debug output. Only the function names,
381 or filenames matching the given debug string is actually
382 printed. This way it is possible to filter out those debug
383 strings that user is not interested in.
385 Fixed a bug in silc_string_regexify.
387 Affected files lib/silcutil/silclog.[ch], and
388 lib/silcutil/unix/silcunixutil.c.
390 * Changed the -d options in both server and Irssi SILC client
391 to take the debug string as argument. Affected files
392 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
394 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
396 * Added silc_hash_babbleprint to create a Bubble Babble
397 Encoded fingerprint. The encoding is developed by Antti
398 Huima (draft-huima-babble-01.txt), and it creates human
399 readable strings out of binary data. Affected file
400 lib/silccrypt/silchash.[ch].
402 * Print the babble print now in addition of fingerprint as well
403 in Irssi SILC client. Affected files are
404 irssi/src/fe-common/silc/module-formats.[ch],
405 irssi/src/fe-common/silc/core/client_ops.c.
407 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
409 * Fixed a security problem found in SKE. The initiator's
410 public key too is now added to the HASH hash value creation
411 which is signed by the responder to create the SIGN value.
412 This will prevent anyone in the middle to lie to the responder
413 about the initiator's public key. If this is done now, the
414 man in the middle will get caught. Updated the protocol
417 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Better installation directory handling. Configure module
420 paths and other paths automatically to example_silc* files
421 in doc/. A patch by toma.
423 * Fixed compiler warning from MPI library, and from SILC RNG.
426 * Added SILC_SERVER_PID_FILE to define the pid file for server.
427 It can be configured with ./configure. A patch by toma.
429 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Find correct make to use in prepare-clean. A patch by
432 toma. Affected file prepare-clean.
434 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
436 * Added irssi variables use_auto_addr, auto_bind_ip,
437 auto_bind_port and auto_public_ip.
439 * Changed the interface for silc_client_send_key_agreement
440 in lib/silcclient/silcapi.h
444 irssi/src/silc/core/silc-core.c
446 lib/silcclient/silcapi.h
447 irssi/src/silc/core/silc-channels.c
448 lib/silcclient/client_keyagr.c
451 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
453 * Added silc_pkcs_public_key_compare to compare two
454 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
456 * Check that the client who set the founder mode on the
457 channel is the same client that is giving the founder
458 mode to itself. It is done by comparing the saved public
459 key (it is saved even in the authentication is passphrase).
460 Affected file silcd/command.c.
462 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
464 * Do not process packet for disconnected socket connection.
465 Affected file lib/silccore/silcpacket.c.
467 * Process the DISCONNECT packet through scheduler in the
468 client library. Affected file lib/silcclient/client.c.
470 * Fixed the silc_client_packet_parse to not to increase
471 the packet sequence number if the conn->sock and the
472 current socket connection is not same. This can happen
473 for example during key agreement when the conn includes
474 multiple socket connections (listeners). Affected file
475 lib/silcclient/client.c.
477 * The sender of the file transfer request now provides also
478 the pointer (listener) for the key exchange protocol. If
479 the listener cannot be created then it sends empty key
480 agreement and lets the receiver provide the listener.
482 Added `local_ip' and `local_port' arguments to the
483 silc_client_file_send. If they are provided they are used,
484 if not then it will attempt to find local IP address, if
485 not found or bind fails then the remote client will provide
488 Affected files are lib/silcclient/client_ftp.c and
489 lib/silcclient/silcapi.h.
491 * Extended the FILE SEND command to support defining the
492 local IP and port for key exchange listener. They are
493 optional. Affected file irssi/src/silc/core/silc-servers.c.
495 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
497 * Defined to WHOIS command reply the sending of fingerprint
498 of the client's public key (if the proof of posession of the
499 corresponding private key is verified by the server).
500 Updated to the protocol specification.
502 * Added support of receiving the client's public key's
503 fingerprint in command reply in client library. Affected
504 file is lib/silcclient/command_reply.c, and
505 lib/silcclient/idlist.[ch].
507 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
509 * Do not send over 128 chars long nickname to the server
510 in NICK command. Affected file lib/silcclient/command.c.
512 * Do not send over 256 chars long channel names to the server
513 in JOIN command. Affected file lib/silcclient/command.c.
515 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Assure that silc_server_close_connection cannot be called
518 twice for same socket context. Affected file is
521 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
523 * Send error message to application if opening file for
524 writing during file transfer fails. Affected file is
525 lib/silcclient/client_ftp.c.
527 Remove all file transfer sessions for a client that we're
528 removing from ID cache.
530 Affected file is lib/silcclient/client_ftp.c.
532 * Fixed silc_net_addr2bin to return correct address. Affected
533 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
535 * Fixed file transfer session removing on signoff notify.
536 Affected file irssi/src/silc/core/silc-servers.c.
538 * Added the SilcClientFileError to be returned in the monitor
539 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
540 Affected file lib/silcclient/silcapi.h.
542 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Fixed a crash in silc_client_ftp_free_sessions and
545 silc_client_ftp_session_free_client. Affected file
546 lib/silcclient/client_ftp.c.
548 * Added `disabled' field in the SilcChannelEntry in the server
549 to indicate if the server entry is disabled. Affected file
550 silcd/idlist.h, silcd/command[_reply].c.
552 * SILC server adds now /var/run/silcd.pid everytime it is
553 started. Affected file silcd/silcd.c.
555 * Added silc_server_packet_send_clients to send a packet to
556 the provided table of client entries. Affected file
557 silcd/packet_send.[ch].
559 * Fixed a crash in client resolving in client_prvmsg.c in
560 client library. Affected file lib/silcclient/client_prvmsg.c.
562 * Do not actually remove the client directly from ID cache
563 during SERVER_SIGNOFF, but invalidate it. This way we
564 preserve the WHOWAS info for the client. Affected file
567 * Fixed SERVER_SIGNOFF notify handling in the server. The
568 server is now able to process incoming SERVER_SIGNOFF notify
569 for a server that it doesn't even know about. It will remove
570 the clients provided in the notify. Affected file
571 silcd/packet_receive.c.
573 * Check for partial packet in data queue after every packet that
574 was found from the queue. Return and wait for more data if

586 * Check that newsize in silc_buffer_realloc is larger than
587 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
589 * Added better monitor of file transfers. It now monitors
590 key agreement protocol during the file transfer too. Added
591 error reporting too. Affected files
592 irssi/src/silc/core/silc-servers.c,
593 irssi/src/fe-common/silc/module-formats.[ch].
595 * Wrote a help file for FILE command.
597 * Added silc_rng_global_get_byte_fast to get not-so-secure
598 random data as fast as possible. Random data is read from

614 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
616 * Assure that silc_client_notify_by_server_resolve does not
617 resolve the client information multiple times. If it cannot
618 be found by the first it cannot be found at all. Affected
619 file lib/silcclient/client_notify.c.
621 * Fixed WHOWAS command reply calling. Affected file
622 lib/silcclient/command_reply.c.
624 * Removed all references to silc_idlist_get_client from the
625 Irssi SILC client since that call is internal call used by
626 the library. The Irssi SILC client will use now client
627 retrieval functions found in silcapi.h.
629 * Fixed a bug in resolving nickname info before sending
630 private message. It used freed memory. Affected file
631 irssi/src/silc/core/silc-servers.c.

657 in packet queue that we are not able to process without first
658 processing packets before them. Affected file silcd/server,
659 lib/silcclient/client.c.
661 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
662 whether library should continue processing the packet.
663 Affected file lib/silccore/silcpacket.h.

696 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Resolve the client info when received private message or
699 channel message for a client which nickname we don't know.
700 Affected files lib/silcclient/client_prvmsg.c and
701 lib/silcclient/client_channel.c.
703 * Do not crash in /KEY if client is not connected. Affected
704 file irssi/src/silc/core/silc-channels.c.
706 * Added SilcClientStatus field to the SilcClientEntry in the
707 lib/silcclient/idlist.h.
709 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
710 is incomplete and is being resolved, it won't be resolved
713 Make sure also that USERS command reply does not resolve
714 twice information. Affected file is
715 lib/silcclient/command_reply.c.
717 Make sure that silc_client_get_clients_by_list does not
718 resolve twice same information.
720 * Check for valid client->id in the silc_server_free_client_data.
721 Affected file silcd/server.c.

736 * Call the silc_server_udpate_servers_by_server in the
737 primary router that comes back online in the backup resuming
738 protocol. Otherwise it routes packets wrong. Affected file
739 silcd/server_util.[ch], silcd/server_backup.c.
741 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
744 lib/silcutil/silcbuffmt.[ch].
746 * Redefined the SILC packet header to include the padding
747 length. Affected file lib/silccore/silcpacket.[ch].
749 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
750 length for maximum padding up to 128 bytes). Affected
751 file lib/silccore/silcpacket.h.
753 * Removed all backwards support for old 0.5.x MAC thingies.
754 The SILC packet header change makes it impossible to be
755 backwards compatible.
757 * Send the ENDING packet with timeout in the backup resuming
758 protocol. This is to assure that all routers has connected
759 to the primary router. Affected file silcd/server_backup.c.
761 * Changed the RNG to take the first IV from random data. It
762 used to take it from zero actually. Changed the RNG also
763 to use /dev/urandom during session. /dev/random is used
764 in initialization. Affected file lib/silccrypt/silcrng.[ch].
766 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
768 * Changed the SILC packet header to have the first two bytes
769 (the packet length) encrypted. Affected files aroung the
770 code tree, lib/silccore/silcpacket.[ch]. Removed the
771 SilcPacketCheckDecrypt callback. It is not needed anymore
772 since the silc_packet_receive_process will determine now
773 whether the packet is normal or special.
775 * Implemented the unidirectional MAC keys. Affected files
776 lib/silcske/silcske.c, silcd/protocol.c and
777 lib/silcclient/protocol.c.
779 * Implemented the packet sequence number to the MAC computation.
780 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
781 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
782 lib/silcclient/protocol.c.
784 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
786 * Allow backup router to announce servers. All servers
787 announced by backup router are added to the global list
788 automatically. Update hte server's socket to our primary
789 router also when backup router announces a server.
790 Affected file silcd/packet_receive.c.
792 * Do not update the client->router in the function
793 silc_server_udpate_clients_by_server if the client is on
794 global list. We might fail to find any specific server
795 for locally connected clients and local cell clients. They
796 should still use the `from' and not `to' as client->router.
797 This fixes backup router resuming protocol. Affected file
800 * Decrease channel statistics count only if the channel
801 deletion worked. Affected files are silcd/server.c and
804 * Added silc_server_update_servers_by_server to update origin
805 of all server entries. Used during backup router protocol.
806 Affected files silcd/server_util.[ch], silcd/server.c. and
807 silcd/backup_router.c.
809 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
810 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
811 silc_hmac_get_hash and silc_hmac_get_name. Affected file
812 lib/silccrypt/silchmac.c.
814 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
816 * Assure that router cannot reroute the same channel message
817 to the sender. Affected file silcd/packet_receive.c.
819 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Made better checks that the channel message is not sent
822 to the router it came from. Affected file is
823 silcd/packet_send.c. Fixed memory leak too.
825 * Announce informations for incoming router connection, but
826 only after checking if it is replaced by backup router.
827 Affected file silcd/packet_receive.c.
829 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
831 * Fixed the backup resuming protocol to work in multiple
832 router environment. Affected file silcd/server_backup.c.
834 * Route packet only to one router in the function
835 silc_server_packet_send_to_channel. Affected file is
838 * Fixed silc_server_send_notify_dest to set the broadcast
839 flag. Fixed the silc_server_send_notify_topic to actually
840 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
841 Affected file silcd/packet_send.c.
843 * Changed the SFTP Filesystem interface. Changed the
844 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
845 the filesystem operation function. The SilcSFTPFilesystem
846 is now a context that is allocated by all filesystem allocation
847 functions and it already includes the operations structure
848 and filesystem specific context. It is given as argument
849 now to the silc_sftp_server_start. This made the interface
850 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
851 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
853 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
855 * Changed the backup router adding and getting interfaces
856 in the server. The router that will be replaced by the
857 specified backup router is now sent as argument. Affected
858 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
861 * Added silc_net_addr2bin_ne to return the binary form of
862 the IP address in network byte order. Affected files
863 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
865 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Check for existing server ID in silc_server_new_server
868 and in silc_server_connect_to_router_final and remove the
869 old entry if it exists. Affected file silcd/packet_receive.c,
872 * Send the channel message always to only one router, either
873 in upstream or downstream. Affected file is
876 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

909 * Assure that if outgoing data buffer is pending do not force
910 send any data. Affected file lib/silcclient/client.c.
912 * Implemented the backup router support when the primary router
913 goes down. The servers and routers can now use the backup
914 router as new primary router without loosing connectivity.
916 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
919 in the server to indicate disabled entry. All data read
920 from the connection will be ignored and no data is sent
921 for entry that is disabled. Affected files are
922 silcd/idlist.h, silcd/server.c.
924 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
926 * Created SFTP client and server test programs in the
927 lib/silcsftp/tests directory.
929 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Implemented memory filesystem (virtual filesystem) for
932 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
935 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Implemented the SFTP (SSH File Transfer Protocol) to the
938 lib/silcsftp. It includes SFTP client and SFTP server
941 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
943 * Moved lib/silccore/silcprotocol.[ch] to the
944 lib/silcutil library.
946 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
947 take variable argument list pointer as argument. Affected
948 file lib/silcutil/silcbuffmt.[ch].
950 * Added silc_buffer_set function that is used to set data
951 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
952 Affected file lib/silcutil/silcbuffer.h.
954 * Changed various routines in the core library to use the new
955 silc_buffer_set instead of allocating new buffer only for
958 * Added 64-bit value formatting and unformatting support to the
959 silc_buffer_[un]format routines. Affected file is
960 lib/silcutil/silcbuffmt.[ch].
962 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
963 to includes/bitmove.h.
965 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Fixed channel user mode saving in client library. Affected
968 file lib/silcclient/command[_reply].c.
970 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
972 * Defined the file transfer to the SILC Protocol. Added
973 new packet type SILC_PACKET_FTP and defined File Transfer
974 Payload. The mandatory file transfer protocol is SFTP
975 (SSH File Transfer Protocol). Affected file in addition
976 of the internet draft is lib/silccore/silcpacket.h.
978 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
979 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
980 is used as part of backup router protocol when the primary
981 router of the cell is back online and wishes to resume
982 the position as primary router.
984 * Redefined the MAC generation keys in the protocol. The
985 same key is not used anymore in both direction. Both
986 direction will now use different keys for sending and
987 receiving. This fixes a potential security flaw. This
988 change causes incompatibilities in the protocol.
990 * Redefined also the MAC computation from the packet.
991 An packet sequence number is now added to the MAC
992 computation. This prevents possible replay attacks against
993 the protocol. This change too causes incompatibilities
996 Added `sequence' field to the SilcPacketContext to hold
997 the current sequence number for the packet.
999 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Added `created' field to the SilcIDListData in the file
1002 silcd/idlist.h to indicate the time when the entry was
1005 * Added `created' field to the SilcChannelEntry too. Affected
1006 file silcd/idlist.h.
1008 * Added `creation_time' aguments to all the announcement functions
1009 in the server. If it is provided then only the entries that
1010 was created after the provided time frame are actually
1011 announced. Affected file silcd/server.[ch].
1013 * The protocol says that the Channel ID's IP address must be
1014 based on the router's IP address. Added check for this in
1015 the silc_server_new_channel when processing incoming New Channel
1016 Payload. Affected file silcd/packet_receive.c.
1018 * Print out the correct version with --version in SILC client.
1019 Affected file irssi/src/silc/core/silc-core.c.
1021 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1024 entry always, not just when the command is coming from client.
1025 Affected file silcd/command.c.
1027 * Added new function silc_server_packet_queue_purge to purge the
1028 outgoing data queue to the network. After the function returns
1029 it is guaranteed that the outgoing packet queue is empty.
1030 Affected file silcd/packet_send.[ch].
1032 * Purge the outgoing packet queue in the rekey protocol's final
1033 callback to assure that all rekey packets go to the network
1034 before quitting the protocol. Affected file silcd/server.c.
1036 * Added silc_client_packet_queue_parse as similar function as
1037 in server to the client library. The affected file is
1038 lib/silcclient/client.c.
1040 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Splitted silcd/server.c and created silcd/server_util.[ch]
1043 for utility functions.
1045 * Added new socket flag SILC_SF_DISABLED to indicate that the
1046 connection is open but nothing can be sent to or received from
1047 the connection. Affected file lib/silcutil/silsockconn.[ch].
1048 The checking for disabled socket is checked in the low level
1049 silc_socket_write and silc_socket_read functions.
1051 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Allow only nicknames and channel names that fits into the
1054 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1056 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * When processing JOIN command reply in server check that if
1059 the channel exists in our global list we'll move it the local
1060 list. Affected file silcd/command_reply.c.
1062 * Fixed the check whether client is joined on the channel already
1063 in JOIN command. Affected file lib/silcclient/command.c.
1065 * Fixed the JOIN command reply to check whether the channel
1066 already exists. Affected file lib/silcclient/command_reply.c.
1068 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Added silc_ske_status_string to map the SKE error numbers
1071 to readable strings. The affected files are
1072 lib/silcske/silcske[_status].[ch].
1074 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * Do not show the private channels on the WHOIS channel list
1077 as it is not allowed by the protocol. The affected file is
1080 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Assure that the packet length digged from the actual packet
1083 is something sensible in the silc_packet_decrypt_rest_special
1084 in lib/silccrypt/silcpacket.c.
1086 * Free and NULL the allocated pointer in silc_hmac_alloc if
1087 the HMAC allocation fails. The affected file is
1088 lib/silccrypt/silchmac.c.
1090 * Print the selected security properties to the log files in
1091 the server. Affected file silcd/protocol.c.
1093 * Add SKE's reference counter even if calling the completion
1094 callback manually. Otherwise it goes negative, although it
1095 does not cause any problems. The affected file is
1096 lib/silcske/silcske.c.
1098 * Remove the client entry with short timeout after giving the
1099 KILL command. Affected file lib/silcclient/command.c.
1101 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1102 case all found clients are already disconnected (WHOWAS would
1103 found them) in the server. Affected file silcd/command.c.
1105 * Update the last_receive (time of last data received) to be
1106 updated only when received private or channel message so that
1107 the idle time showed in WHOIS makes more sense.
1109 * Added boolean field `valid' in to the SilcClientEntry in the
1110 client library to indicate whether the entry is valid or not.
1111 This fixes the nickname change bug on channel when changing
1112 the nickname to be same than the old (like nick to Nick) the
1113 nickname formatter doesn't set the new nick anymore to Nick@host.
1114 Affected file lib/silcclient/idlist.[ch].
1116 * Now actually fixed the nickname changing on disconnection.
1117 Added new function silc_change_nick to the Irssi SILC Client.
1118 Affected file irssi/src/silc/core/client_ops.c,
1119 irssi/src/silc/core/silc-nicklist.[ch].
1121 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Check that the public key exists in the GETKEY command before
1124 trying to encode it. Affected file silcd/command.c.
1126 * Print some notifications on received public keys with GETKEY
1127 command in the Irssi SILC Client. Affected files are
1128 irssi/src/fe-common/silc/module-formats.[ch],
1129 irssi/src/silc/core/client_ops.c.
1131 * Use IDENTIFY command to resolve the server information in the
1132 GETKEY command instead of INFO command. Affected file
1133 lib/silcclient/command.c.
1135 * All command reply functions in the client library now calls
1136 the pending command reply callbacks even if an error has
1137 occurred. The server has done this a long time and now it was
1138 time to move the client library to this as well. Now all
1139 errors can be delivered back to the pending command reply
1140 callbacks if necessary. Affected files are
1141 lib/silcclient/command[_reply].[ch].
1143 * Change the nickname on disconnection back to the username
1144 because in reconnect the server will enforce it to it anyway.
1145 Affected file irssi/src/silc/core/silc-servers.c.
1147 * Fixed a config file parsing bug in the Irssi SILC client.
1148 Affected file irssi/src/silc/core/clientconfig.c.
1150 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * When printing the channel mode on JOIN, verify that the
1153 channel key and channel's HMAC are valid. Affected file
1154 irssi/src/silc/core/client_ops.c.
1156 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1159 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1160 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1162 * Removed channel key rekey task deleting from the function
1163 silc_server_save_channel_key. Affected file silcd/server.c.
1164 Added explicit timeout task context instead that is used to
1165 delete the task if we are registering a new task before the
1166 new task has elapsed.
1168 * When channel key rekey occurs the client library now saves
1169 the old channel key for a short period of time (10 seconds) and
1170 is able to use it in case some is still sending channel
1171 messages encrypted with the old key after the rekey. Affected
1172 file lib/silcclient/[idlist.h|client_channel.c].
1174 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1176 * Added check to the silc_server_new_id_real to not accept
1177 new ID if it is the sender's own ID. Affected file is
1178 silcd/packet_receive.c.
1180 * Assure that we do not announce ourself or the one we've
1181 sending our announcements when we're router and are announcing
1182 servers to our primary router. Affected file silcd/server.c.
1184 * Fixed silc_server_command_identify_check_client to assemble
1185 correct WHOIS packet. It send corrupted WHOIS packet and
1186 caused problem with router to router connections. Affected
1187 file silcd/command.c.
1189 Fixed also silc_server_command_whois_check the same way
1190 as for the IDENTIFY command.
1192 * Added new SilcIDListStatus to the server in the SilcIDListData
1193 structure. The status now includes the current status of
1194 the entry (like registered, resolved etc.). Affected file
1195 silcd/idlist.[ch]. Defined a bunch of different status types
1196 as well. This replaced the old boolean registered field as well.
1198 Added resolve_cmd_ident field to the SilcClientEntry structure
1199 too so that if the entry is for example being resolved so
1200 another command may attach to the same pending command reply
1201 without requiring to resolve the same entry again. This concept
1202 should optimize the WHOIS and the IDENTIFY resolving under
1203 heavy load by taking away unnecessary resolving for entries
1204 that are being resolved already.
1206 Added support for adding multiple pending commands for one
1207 command idenfier. Affected file silcd/command[_reply].[ch].
1209 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1210 before deleting the data. Otherwise the hash table will have
1211 freed data in comparison functions. Affected file is
1212 silcd/command_reply.c.
1214 * Fixed silc_idlist_replace_client_id to add the new entry to
1215 the cache with NULL nickname. Otherwise there will be invalid
1216 memory as the nickname after the nickname is freed. Affected
1217 file silcd/packet_receive.c.
1219 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1220 saved into wrong slots because the previous number of entries
1221 was not taken into account. Affected file silcd/idlist.c.
1222 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1224 * If we are router and we receive JOIN notify to a channel that
1225 does not have any users then notified client is marked as the
1226 channel founder, as it is it. The affected file is
1227 silcd/packet_receive.c
1229 * Added to the extended hash table API's table_del_*ext functions
1230 the destructor as argument too, so that the caller can decide
1231 which destructor to use or whether to use destructor at all.
1232 Affected file lib/silcutil/silchashtable.[ch].
1234 * Fixed ID Cache purging. It actually deleted the entries from
1235 the hash table after the data was freed. The hash table ended
1236 up comparing freed memory. The affected file is
1237 lib/silccore/silcidcache.c.
1239 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * Fixed Irssi SILC client's KILL command's HELP syntax.
1243 * The USERS command now resolves the detailed user information
1244 if the userinfo field is missing. Affected file is
1245 lib/silcclient/command_reply.c.
1247 * Do not print error in silc_file_read if the read file does
1248 not exist. Just silently return NULL. Affected file is
1249 lib/silcutil/silcutil.c.
1251 * Fixed the silc_log_output to not wine about NULL filename
1252 and to not create some bogus " " filename. Affected file is
1253 lib/silcutil/silclog.c.
1255 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Fixed various printing bugs on the user interface in the
1258 Irssi SILC Client. Minor changes that were forgotten from
1261 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Fixed the configure.in.pre and the compilation and distribution
1264 environment to support the new autoconf 2.52. That version is
1265 now required to compile the CVS trunk.
1267 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1270 to generally parse user@fqdn format strings. Affected file
1271 lib/silcutil/silcutil.c.
1273 * Added nickname_format and nickname_force_format fields to the
1274 SilcClientParams structure. The first one defines the format
1275 for the nicknames that the library will enforce if the receives
1276 multiple same nicknames. The second one is boolean value and
1277 can be used to force the library to always enforce the format
1278 to the nicknames regardles whether there are multiple nicknames
1279 or not. This configurable formatting was employed to flexibly
1280 support accessing multiple nicknames from the user interface.
1281 The userinterface can now set the nicknames to what ever format
1282 they prefer. Affected file lib/silcclient/silcapi.h.
1284 Added function silc_client_nickname_format to the file
1285 lib/silcclient/idlist.c. It performs the nickname formatting.
1287 Added new field `hostname´ to the SilcClientEntry context.
1288 It holds the hostname of the client. Affected file is
1289 lib/silcclient/idlist.h.
1291 * Irssi SILC Client sets the nicknames in nick@hostn format.
1292 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1293 irssi/src/silc/core/silc-core.c.
1295 The WHOIS printing now also shows both the real nickname and
1296 the formatted nickname so that user knows how to access the
1297 user if there are multiple same nicknames cached. Affected
1298 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1299 printing formatting too to take the hostname now as a separate
1300 argument. The Affected file is
1301 irssi/src/fe-common/silc/modules-formats.[ch].
1303 * Changed the silc_client_get_clients_local to accept the formatted
1304 nickname as argument. It accepts the real nickname too but the
1305 formatted nickname can be used to find the true entry from
1306 multiple entries. Affected file lib/silcclient/silcapi.h and
1307 lib/silcclient/idlist.c.
1309 * Added nickname_format_parse field to the SilcClientParams.
1310 It is a callback function provided by the application to parse
1311 the nickname out of the formatted nickname string. The library
1312 calls it to get the nickname from the formatted string. Since
1313 the application generally knows better the format of the nickname
1314 string it parses it instead of the library, even though library
1315 encodes the formatted string. If the callback function is not
1316 provided then the library will use the string as is. The
1317 affected file is lib/silcclient/silcapi.h.
1319 * All the nickname strings passed to the client library in
1320 commands are now expected to be formatted nickname strings.
1321 If the command does not support the formatted nickname string
1322 it will assume that the sent string is the actual nickname.
1323 Affected file lib/silcclient/command.c.
1325 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Added public key authentication support to OPER and SILCOPER
1328 commands in the client library. Affected file is
1329 lib/silcclient/command.c.
1331 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1333 * Changed the get_auth_methdod client operation to be asynchronous.
1334 It can be async if the application resolves the authentication
1335 method from the server during the negotiation. Added new
1336 SilcGetAuthMeth completion callback that the application will
1337 call after resolving the authentication method.
1339 Added function silc_client_request_authentication_method that
1340 the application can use to resolve the authentication method
1341 from the server. Added also SilcConnectionAuthRequest callback
1342 that the library will call after the server has replied. The
1343 application can call this function if it does not know the
1344 current authentication method.
1346 Affected files are lib/silcclient/client.c and
1347 lib/silcclient/silcapi.h.
1349 * The Irssi SILC client now automatically resolves the authentication
1350 method incase any configuration information is not present (and
1351 currently there never is). The affected file is
1352 irssi/src/silc/core/client_ops.c.
1354 * Fixed public key authentication from the client library.
1355 Affected file lib/silcclient/protocol.c. Changed also the
1356 protocol specification about the public key authentication in
1357 the connection authentication protocol. The actual data to be
1358 signed is now computed with a hash function before signing.
1360 * Fixed the public key authentication from the server as well.
1361 Affected file silcd/protocol.c.
1363 * Removed the mlock()'s from the memory allocation routines.
1364 Affected file lib/silcutil/silcmemory.c. The ./configure does
1365 not check anymore for the mlock(). Affected file is
1368 * Fixed USERS command in server to allow the execution of the
1369 command for private and secret channels if the client sending
1370 the command is on the channel. Affected file silcd/command.c.
1372 * Fixed silc_client_get_clients_local to return the clients
1373 count correctly. It could return wrong value. Affected file
1374 lib/silcclient/idlist.c.
1376 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1379 types. The assembler optimizations seemed not to like 64-bit
1380 data types. The assmebler optimizations thus are now enabled
1381 also for BSD systems as opposed to only enable them for Linux.
1383 * Do not check for threads at all on BSD systems. Affected
1384 file configure.in.pre.
1386 * Removed -n and -h options from the Irssi SILC Client since
1387 they are not used in silc.
1389 * Fixed the prime generation to assure that the first digit
1390 of the generated random number is not zero since our conversion
1391 routines does not like number strings that starts with zero
1392 digit. If zero digit is seen the random number is regenerated.
1393 This caused some corrupted RSA keys when the zero first digit
1394 was met. Affected file lib/silcmath/silcprimegen.c.
1396 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Fixed WIN32 configuration in the ./configure script.
1399 Fixed to include xti.h on environments that has it.
1400 Patches by Carsten Ilchmann and andrew.
1402 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Changed the silc_id_create_client_id to be collision
1405 resistant. It is now assured that there cannot be created
1406 two same client ID's. I suspect that some weird bugs in
1407 the server were actually caused by duplicate Client IDs.
1408 Affected file silcd/serverid.[ch]. A router receiving
1409 new ID now also assures and informs the sending server
1410 if the ID caused collision.
1412 * Changed the silc_id_create_channel_id to also assure that
1413 there are no collisions.
1415 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Statement about ignoring the Mutual Authentication flag when
1418 performing rekey with PFS was a bit misleading. It is ignored
1419 if it was set in the initial negotiation, it cannot be even
1420 set in the rekey. Fixed in the ke-auth draft. Started the
1421 new versions of the protocol drafts in the doc/.
1423 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Fixed a bug in silc_client_command_identify_save when saving
1426 new channel information. The channel name was no duplicated
1427 and caused crash on exit. Affected file is
1428 lib/silcclient/command_reply.c.
1430 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Fixed the getkey command handling in the server. Send just
1433 empty OK reply to the sender if the key could not be fetched
1434 (but everything else was ok, like the key just was not available).
1435 Changed the public key parameter to optional in the protocol
1436 specs so that empty OK reply can be sent. Affected file
1439 Added a message to Irssi SILC client to tell to user if the
1440 server did not return a public key.
1442 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Fixed a channel key regeneration bug. It registered new
1445 timeout tasks exponentially until all system resources were
1446 used. Affected file silcd/server.c.
1448 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Added the SILC Document generator to the scripts/silcdoc.
1451 It can be used to generate the Toolkit Reference Manual out
1452 of the source tree. Internally it will also use the RoboDoc
1453 generator now imported in util/robodoc.
1455 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Added couple of return's in rekey protocol if error orccurred
1458 during the protocol. The execution must be terminated.
1459 Affected file silcd/protocol.c. Also, terminate the protocol
1460 always with timeout.
1462 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * The client's Client ID was created initally from the wrong
1465 nickname (it could have been in format nick@host) in the
1466 silc_server_new_client. Affected file silcd/packet_receive.c
1468 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Added some SILC_LOG_ERROR's to various error conditions
1471 if client could not be added to ID cache. Affected files
1472 silcd/packet_receive.c and silcd/server.c.
1474 * When client's sock->user_data is freed, NULL also the
1475 client->router and client->connection pointers. Added check
1476 for these pointers being NULL to various places around the
1477 code. Affected file silcd/server.c.
1479 * Added client->data.registered == TRUE checks to various
1480 places around the code to assure that unregistered client's
1481 are not handled when it is not allowed. Affected file
1484 * Added `bool registered' fields to all
1485 silc_idlist_[server|client]_get_* routines to indicate whether
1486 the fetched client needs to be registered or not. Affected
1487 file silcd/idlist.[ch].
1489 * Add your own entry as registered to the ID cache in the
1490 server. Affected file server.c.
1492 * Fixed a bug in silc_server_new_server. The SilcServer was
1493 set as the new server's context instead of SilcServerEntry.
1494 This naturally caused some weird bugs.
1496 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Do not delete the channel rekey task when adding it
1499 for in silc_server_create_channel_key.
1501 * Changed the silc_server_create_channel_key to return
1502 TRUE or FALSE to indicate the success of the channel key
1505 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Fixed MSVC++ project files and added missing files to
1508 Makefiles under win32/.
1510 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Do not add TCP_NODELAY flag if the operating system
1513 does not have it defined. Affected files are
1514 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1516 * Fixed buffer overflow from Irssi SILC Client. Affected
1517 file irssi/src/fe-common/core/themes.c.
1519 * Fixed double free in client library in the file
1520 lib/silcclient/client.c when disconnecting from server.
1522 * Applied double free patch from cras to Irssi SILC client.
1523 Affected files irssi/src/core/[modules/expandos].c
1525 * Fixed the disconnection handling to Irssi SILC Client.
1526 The application must call silc_client_close_connection
1527 in ops->connect client operation in case of failure of
1528 the connection. Affected file is
1529 irssi/src/silc/core/client_ops.c.
1531 * Do not set sock->protocol to NULL in the function
1532 silc_client_close_connection after executing the protocol's
1533 final callback since the sock might not be valid anymore.
1534 Affected file lib/silcclient/client.c.
1536 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Do not enable SILC_THREADS if the linking with libpthread
1539 did not happen. Affected file configure.in.pre.
1541 * Added notion to protocol specification that server must
1542 verify the sent authentication payload with CMODE when
1543 setting the channel founder key. Implemented it to the
1544 server. Affected file silcd/command.c.
1546 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Added _EXTRA_DIST SILC distribution variable to the
1549 distributions file. It is used to conditionally add extra
1550 files or directories to the specific distribution. Affected
1551 files ./prepare, Makefile.am.pre and distributions.
1553 Removed the `_' from the start of the distribution names.
1556 * Added README.WIN32 for instructions to compile the Toolkit
1559 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Fixed a double free in disconnection in the server. Affected
1562 file is silcd/server.c.
1564 * Fixed the lib/silcske/groups.c to work now also with GMP
1565 MP library. The string conversion did not work when using
1566 specific base and the base is indicated in the string as well.
1568 * Created win32/ directory which now includes MSVC++ specific
1569 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1570 It will appear only in the toolkit distribution
1572 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Changed the key material distribution function in case when
1575 the hash output is too short. The data is now concatenated
1576 a bit differently than it used to. Made the change to the
1577 SKE protocol specification.
1579 * Added better GMP detection to configure.in.pre. A patch
1582 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Fixed a minor bug in SKE that might cause some problem on
1585 some platforms. Affected file lib/silcske/silcske.c.
1587 * Added the cookie checking for initiator in the SKE. It checks
1588 that the responder returns the sent cookie unmodified. The
1589 affected file is lib/silcske/silcske.c. Added new SKE
1590 error type INVALID_COOKIE that can be sent during the
1591 negotiation. Fixed some memory leaks as well.
1593 * Added the "invalid cookie" error message to Irssi SILC client's
1596 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Added `task_max' field to the SilcClientParams to indicate
1599 the maximum tasks the scheduler can handle. If set to zero,
1600 default values are used. Affected file lib/silcclient/silcapi.h.
1602 * Fixed memory leaks in silc_client_close_connection. Affected
1603 file lib/silcclient/client.c.
1605 * Added silc_client_del_client_entry to client library to free
1606 all memory of given client entry. Affected file is
1607 lib/silcclient/idlist.[ch].
1609 * Added new functions silc_client_del_channel and
1610 silc_client_del_server to delete channel and server entries.
1611 Affected file lib/silcclient/[silcapi.h/idlist.c].
1613 * Removed silc_client_del_client_by_id from silcapi.h.
1615 * Fixed the INFO command to return the server's own info
1616 correctly when querying by Server ID. Affected file is
1619 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1621 * Removed the non-blocking settings in WIN32 code in the
1622 silc_sock_[read/write] and added SleepEx instead. Affected
1623 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1624 of input data is now checked with FIONREAD and ioctlsocket.
1626 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Call silc_schedule_task_del_by_context in the
1629 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1630 Affected file lib/silccore/silcprotocol.c.
1632 * Call silc_protocol_cancel for active protocols in the
1633 silc_server_close_connection if the funtion
1634 silc_server_free_sock_user_data has not been called.
1635 Affected file silcd/server.c.
1637 * Generic tasks cannot be deleted using the del_by_fd
1638 task deleting function since generic tasks does not match
1639 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1641 * Added a notion to SILCOPER help file that the SILCOPER works
1642 only on router server, not on normal server.
1644 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Added for WIN32 support for the new scheduler as well.
1647 Affected file lib/silcutil/win32/silcwin32schedule.c.
1649 * Fixed the SHA1 implementation to work on various platforms.
1651 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1654 API. It is part of the scheduler now. Everything else is
1655 as previously but some functions has changed their names.
1656 Checkout the lib/silcutil/silcschedule.h for the interface.
1657 Updated all applications to use the new interface. Affected
1658 files are lib/silcutil/silcschedule.[ch].
1660 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Found a bug in the SKE implementation. The HASH value,
1663 specified by the protocol, was not computed correctly. The
1664 public key of the responder was not added to the computation
1665 even though it is mandatory. Affected file lib/silcske/silcske.c.
1666 This unfortunately causes incompatibilities with older
1667 clients and servers.
1669 * Added WIN32 specific network init and uninit functions:
1670 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1671 the Winsock2. Affected file lib/silcutil/silcnet.h and
1672 lib/silcutil/win32/silcwin32net.c.
1674 * Set the socket always to nonblocking mode on WIN32 after
1675 reading data or writing data. Affected file is
1676 lib/silcutil/win32/silcwin32sockconn.c.
1678 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * Fixed various compilation problems under WIN32. Affected
1681 files lib/silcutil/win32/silcwin32thread.c and
1682 lib/silcutil/win32/silcwin32schedule.c.
1684 * Removed all _internal.h #includes from public header
1685 files. Internal headers must never be included from
1688 Removed also the lib/silcske/payload_internal.h file.
1690 * All include files that may be needed (public and some others
1691 included by the public headers) by application developers are
1692 now copied to the ./includes directory. It does not copy any
1693 internal headers. Affected file Makefile.defines.pre and all
1694 Makefile.am's under lib/ and subdirs.
1696 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Do not change the ~/.silc directory's permissions automatically.
1699 Affected file irssi/src/silc/core/clientutil.c.
1701 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Do not cancel the protocol in silc_server_close_connection
1704 it might cause recursion. Now cancelled in the function
1705 silc_server_free_sock_user_data. Affected file silcd/server.c.
1707 * Fixed the silc_server_remove_clients_by_server to regenerate
1708 the channel keys correctly finally. Added also new function
1709 silc_server_remove_clients_channels to actually do it.
1710 Affected file silcd/server.c.
1712 * Fixed the silc_server_new_channel to not crash by giving
1713 wrong router to the new channel. Affected file is
1714 silcd/packet_receive.c.
1716 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1719 which is given as argument to the silc_client_alloc now.
1720 It can be used to configure the client and set various parameters
1721 that affect the function of the client.
1723 * The USERS command in server did not check whether the channel
1724 is private or secret. Affected file silcd/command.c.
1726 * Added new argument to the USERS command in protocol specification.
1727 The USERS command now can take the channel name as argument
1728 as well. Added support for this in client and server and
1729 updated the protocol specs.
1731 * Completed the GETKEY command in client. It can be now used
1732 to fetch also servers public key not only some clients.
1733 Affected files lib/silcclient/command[_reply].c.
1735 * Added silc_client_get_server to return server entry by the
1736 server name. Affected files lib/silcclient/silcapi.h and
1739 * Redefined the IDENTIFY command in protocol specification to be
1740 more generic. It now can be used to query information about
1741 any entity in the SILC Network, including clients, servers and
1742 channels. The query may be based either the entity's name
1743 or the ID. Added support for this in both client and server.
1745 Affected files silcd/command.c and lib/silcclient/command.c
1746 and command_reply.c.
1748 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1749 the _from_client and _from_server functions. Affected file
1752 * Added silc_client_get_channel_by_id_resolve to the file
1753 lib/silcclient/silcapi.h to resolve channel information by
1754 its ID. Added also silc_client_get_channel_by_id that
1755 does not resolve it from the server.
1757 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Added SilcServerEntry context into the client library
1760 to represent one server. The INFO command now allocates
1761 these to save the resolved server info. For now on the
1762 client library will also keep information about servers,
1763 connected and resolved with INFO.
1765 The INFO command now allocates the SilcServerEntry context
1766 and saves the server info there. The COMMAND_REPLY in
1767 the INFO now returns the parameters to application in
1768 same order as defined in the protocol specification.
1770 The entries are cached in the client->server_cache.
1772 * The INFO command is now issued after received the Client ID
1773 from the server. Affected file lib/silcclient/client.c.
1775 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1776 to the application as the mode changer might be server.
1777 It is guaranteed that NULL is not returned anymore to the
1778 application. Affected file lib/silcclient/client_notify.c.
1780 The ID Type is now also passed to the application so that
1781 it can check whether the returned entry is SilcClientEntry
1784 Added new function silc_client_get_server_by_id to return
1785 the server entry by ID. Affected files are the
1786 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1788 * Do not create the channel in the Irssi SILC Client when issuing
1789 the JOIN command but when received the sucessful JOIN command
1790 reply. Otherwise the channel might get created even though we
1791 could not join it. The Affected file is
1792 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1794 * Fixed a channel joining bug in router. The router must also
1795 check the channel modes, invite and ban lists etc. when serving
1796 the JOIN command sent by normal server. Affected file is
1797 silcd/command.c. The router now resolves the client's
1798 information from the server who sent the JOIN command if it
1799 does not know it, and processes the JOIN command only after
1802 * Changed the SilcCommandCb to take new argument; void *context2.
1803 Affected file lib/silccore/silccommand.h
1805 The second argument in the command callbacks in the server now
1806 includes the SilcServerCommandReplyContext if the command was
1807 called as pending command callback from the command reply.
1808 Otherwise it is NULL. When called as pending the status of the
1809 command reply will be checked and if it was erronous the
1810 error will be sent to the original sender of the command.
1811 This way the client always receives the error messages even
1812 though the server was actually the one who received the error
1813 when it resent the command to router, for example. Affected
1814 files silcd/command[_reply].[ch].
1816 * Fixed sending WHOWAS command's error message to client if
1817 the requested client could not be found. It was missing.
1820 * Changed the CMODE and CUMODE commands reply arguments in the
1821 protocol specification. The Channel ID is now sent in both
1822 of the commands to identify the channel. Implemented this
1823 new feature to the client and server. Affected files
1824 lib/silcclient/command_reply.c and silcd/command.c.
1826 * Made better checks for invite and ban lists in the JOIN
1827 command in server. Affected file silcd/command.c.
1829 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * The server now performs the incoming host IP/DNS lookup
1832 using the silc_socket_host_lookup and thus does not block
1833 the server anymore. Affected file silcd/server.c.
1835 * Completed the multi-thread support for SILC Scheduler in
1836 the lib/silcutil/silcschedule.c.
1838 * Fixed the configure.in.pre to detect the pthread correctly
1841 * Fixed a deadlock in silc_task_queue_wakeup in the file
1842 lib/silcutil/silctask.c.
1844 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Added new function silc_schedule_wakeup that is used in
1847 multi-threaded environment to wakeup the main thread's
1848 schduler. It needs to be used when a thread adds a new task
1849 or removes a task from task queues. After waking up, the
1850 scheduler will detect the task queue changes. If threads
1851 support is not compiled in this function has no effect.
1852 Implemented the wakeup mechanism to both Unix and WIN32
1853 systems. Affected files are lib/silcutil/silcschedule.[ch],
1854 lib/silcutil/unix/silcunixschedule.c and the
1855 lib/silcutil/win32/silcwin32schedule.c.
1857 * Added new function silc_task_queue_wakeup to wakeup the
1858 scheduler by the specified task queue. Affected file
1859 lib/silcutil/silctask.[ch].
1861 * The silc_socket_host_lookup_start now wakes up the scheduler
1862 after adding the timeout task. Affected file is
1863 lib/silcutil/silcsockconn.c.
1865 * The silc_socket_host_lookup is synchronous now if the threads
1866 support is not compiled in. However, the callback is still
1867 called asyncronously through the scheduler, anyway. Affected
1868 file lib/silcutil/silcsockconn.c.
1870 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Added new function silc_socket_host_lookup to perform
1873 asynchronous IP and FQDN lookups for the socket connection.
1874 Affected files lib/silcutil/silcsockconn.[ch].
1876 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1879 that may or may not compile the mutex support in.
1881 Changed the silc_mutex_alloc interface. It allocates the
1882 mutex now to the sent pointer and returns TRUE or FALSE.
1884 Affected file lib/silcutil/silcmutex.h.
1886 * Wrote the SILC Task Queue interface to support multi-threads.
1887 Affected file lib/silcutil/silctask.[ch].
1889 * Wrote the SILC Scheduler to support multi-threads. Affected
1890 file lib/silcutil/silcschedule.c.
1892 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1895 in lib/silcutil/win32/.
1897 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Defined SILC Mutex API and SILC Thread API and implemented
1900 them for Unix. Affected files are
1901 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1902 lib/silcutil/unix/silcunixmutex.c and
1903 lib/silcutil/unix/silcunixthread.c.
1905 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed the silc_server_remove_clients_by_server's channel
1908 key re-generation. The hash table handling was incorrect
1909 and would not work with many channels. Affected file is
1912 * Fixed some memory leaks around the server code.
1914 * Rewrote the silc_server_get_users_on_channel to support IPv6
1915 based Client ID's. Affected file silcd/server.c.
1917 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1918 specification. However, a separate document must be written
1919 to define the detailed signing procedure and the payload
1920 associated with the flag. Defined the flag to the
1921 lib/silccore/silcchannel.h as well.
1923 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Changed the dynamic tables to static size tables in the
1926 lib/silccrypt/silchmac.c.
1928 * Removed GCC dependencies from the code. A patch by cras.
1930 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Do not show the error "Error receiving packet bla bla"
1933 in server if it really was not an error (-2 means that reading
1934 is pending). Affected file silcd/server.c.
1936 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Fixed a possible crash in silc_server_remove_clients_by_server
1939 in silcd/server.c. Fixed there also some memory leaks.
1941 * Fixed the silc_idlist_replace_client_id. It could replace
1942 wrong key in the hash table. Affected file silcd/idlist.c.
1944 * Do not check whether there are global users on the channel
1945 if the channel->global_users is FALSE. Affected functions
1946 silc_server_remove_from_one_channel and
1947 silc_server_remove_from_channels in silcd/server.c. Also,
1948 do not check if the removed client is local as we can be
1949 sure that global client was not removed from the channel
1950 and checking for global users is not needed.
1952 * The silc_server_remove_clients_by_server now re-generates
1953 the channel keys correctly for those channels that had
1954 clients removed from them. Affected file silcd/server.c.
1956 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Found the reason of random crashes in the server. We weren't
1959 ignoring the SIGPIPE signal (which can be sent in write())
1960 and it crashed the server. Affected file silcd/silcd.c.
1962 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Assure that sock->user_data is not NULL in the function
1965 silc_server_packet_send in silcd/packet_send.c.
1967 * Disconnect the remote connection if it could not be added
1968 to any ID lists in the server. The affected file is
1971 * Check in silc_server_packet_send[_real/dest] that the
1972 socket is not disconnecting and ignore the data if it is.
1973 Affected file silcd/packet_send.c.
1975 * Define inline to __inline on native WIN32 compilation.
1976 Affected file includes/silcwin32.h.
1978 * Added some explicit type casts for inline code since MSVC
1979 require them. Affected files lib/silcutil/silcbuffer.h,
1980 lib/trq/silcdlist.h and lib/trq/silclist.h.
1982 * Print warning in log files from now on if the packet
1983 decryption fails. Affected file silcd/server.c.
1985 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Changed the `say' client operation's interface to accept
1988 new `type' argument to indicate the type of the message sent
1989 by the library. The application may filter the library's
1990 messages according the type. The affected file is the
1991 lib/silcclient/silcapi.h.
1993 * Added two new functions to lib/silcclient/silcapi.h:
1994 silc_client_del_client and silc_client_del_client_by_id.
1995 Affected file lib/silcclient/idlist.c.
1997 * Moved the clientincludes.h from includes/ to silc/ and
1998 serverincludes.h from includes/ to silcd/.
2000 * The modes for the CMODE and CUMODE are now passed as
2001 uint32 for application with COMMAND_REPLY. The affected
2002 file is lib/silcclient/command_reply.c.
2004 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * /WHOIS without arguments shows client's own information.
2007 Affected file lib/silcclient/command.c.
2009 * Changed PING to not accept any arguments. The specs
2010 says that client can ping only the connected server so
2011 requiring an argument is not needed. Affected file is
2012 lib/silcclient/command.c.
2014 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Fixed a fatal bug in private message sending and reception
2017 encryption and decryption when using private message keys.
2018 The implementation was incorrect and did not follow the
2019 specification. It causd that some of the message were
2020 lost since it did not use the sending and receiving keys
2021 as the protocol suggests. This has been fixed and will cause
2022 incompatibilities with older clients when sending private
2023 message encrypted with private message keys. Affected files
2024 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2025 and various other in Irssi SILC Client.
2027 Added `responder' boolean argument to the functions
2028 silc_client_add_private_message_key[_ske] to indicate when
2029 the key is added as responder or initiator of the key
2032 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2034 * Removed the silc_ske_check_version function and created
2035 a SilcSKECheckVersion callback. Added also a function
2036 silc_ske_set_callbacks that is now used to set all SKE
2037 callbacks. The callback functions are not given to
2038 the SKE functions anymore, but this function is used to
2041 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2043 * Added `silc_version' argument to the silc_client_alloc
2044 to define the version of the application for the library.
2045 The library will use the version string to compare it
2046 against the remote host's (usually a server) version
2047 string. Affected file lib/silcclient/silcapi.h
2049 * Added the KE protocol context to Key Agreement context
2050 in client library so that we can abort the SKE if it
2051 is in process when we get timeout. Affected file is
2052 lib/silcclient/client_keyagr.c.
2054 * Do not resolve the client ID forever if it returns in the
2055 first time that such client does not exist. This was done
2056 for example with private message. Affected file is
2057 lib/silcclient/client_prvmsg.c.
2059 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2061 * Do not add regex.h for WIN32. The affected file
2062 includes/silcincludes.h.
2064 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2065 not work yet 100%. It generates the DLL's automatically
2066 when compiling with --with-win32 under cygwin.
2068 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * lib/contrib/regex.c is not compiled on WIN32.
2072 * Added silc_net_get_socket_opt function to the
2073 lib/silcutil/silcnet.h.
2075 * Added includes/silcwin32.h for WIN32 specific includes
2078 * Do not use ptime structure or any of the posix process
2079 functions on WIN32 in lib/silccrypt/silrng.c.
2081 * Added silc_gettimeofday to provide generic function
2082 for struct timeval on all platforms. Added the function
2083 to lib/silcutil/silcutil.h.
2085 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2088 library as they clearly belong there. As a plus side we
2089 can make the actual socket connection routines platform
2092 Added also new generic function silc_socket_read and
2093 silc_socket_write (that used to be silc_packet_[read/write].
2094 The implementation of these are platform specific.
2096 * Added WIN32 specific routines of silc_socket_[read/write]
2097 to lib/silcutil/win32/silcwin32sockconn.c.
2099 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Added preliminary support for native WIN32 compilation under
2102 cygwin (using the -mno-cygwin option for GCC) to the
2103 ./configure.in.pre. The --with-win32 now prepares the
2104 compilation for native WIN32.
2106 * Rewrote the SILC Scheduler interface in the file
2107 lib/silcutil/silcschedule.h. The scheduler is now context
2108 based and does not have anymore any global static scheduler.
2109 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2110 and created lib/silcutil/win32 directory for WIN32 based
2113 * Added Unix specific network routines to the
2114 lib/silcutil/unix/silcunixnet.c and the old
2115 lib/silcutil/silcnet.c includes now only generic routines.
2117 Added WIN32 specific network routines to the
2118 lib/silcutil/win32/silcwin32net.c.
2120 * Added Unix specific utility functions from the
2121 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2123 * Added WIN32 SILC Scheduler to the file
2124 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2127 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Do not handle JOIN notify in the server if the target client
2130 is not registered (idata->registered == FALSE). The affected
2131 file is silcd/packet_receive.c.
2133 * Update the nickrec->founder in event_cumode in the Irssi SILC
2134 client. Affected file irssi/src/silc/core/silc-channels.c.
2136 * Fixed the CUMODE_CHANGE notify handling in the server when
2137 server and router are announcing their clients on channels.
2138 Now the mode changes are saved and notified correctly. The
2139 affected file is /silcd/packet_receive.c.
2141 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2142 They really did not replace the cache entry in the ID Cache.
2143 Now they do that. Affected file silcd/idlist.c.
2145 * Fixed the KICK notify handling in the Irssi SILC client to
2146 update the channel records so that the kicked client does not
2147 appear to be on the channel. The affected file is
2148 irssi/src/silc/core/silc-channels.c.
2150 * Always update the conn->current_channel when executing command
2151 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2153 * Fixed the KILL notify handling in Irssi SILC client to remove
2154 the killed client on all channels.
2156 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Fixed the silc_parse_command_line to remove extra spaces
2159 from the start and end of the arguments. Affected file is
2160 lib/silcutil/silcutil.c.
2162 * Cancel and free any active protocol in the function
2163 silc_server_close_connection. Affected file silcd/server.c.
2165 * Cancel and free any active protocol in the function
2166 silc_client_close_connction. Affected file is
2167 lib/silcclient/client.c.
2169 * Do not execute the KILL command for clients that are in
2170 history (ie. they are not in the network). Affected file is
2173 * Fixed KILL notify handling, client does not crash anymore.
2174 Affected file irssi/src/silc/core/silc-channels.c.
2176 * Reduced the default packet buffer size from 2048 to 1024 in
2177 lib/silccore/silcpacket.c.
2179 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2180 counter to the SKE context that is incresed when the SKE library
2181 performs async operation outside the library. If the outside
2182 process frees the SKE context and FREED status will be set
2183 and the library will detect after the sync operation that the
2184 libary is freed. The affected files are
2185 lib/silcske/silcske[_status].[ch].
2187 * Resolve the client entry information in the function
2188 silc_client_channel_message to assure that NULL pointer is not
2189 passed as client entry to the application. */
2191 * Fixed the task timeout calculation to assure that there is
2192 never negative timeouts. The affected file is
2193 lib/silcutil/silcschedule.c.
2195 * Fixed the channel user mode notification sending in server.
2196 It was sent point-to-point to the router (or to server by router)
2197 but it needs to be destined to a channel. The routines now
2198 supports sending the channel user mode notifys to the channels
2199 when announcing clients and channels. Affected files are
2200 silcd/server.c and silcd/packet_receive.c.
2202 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2203 It did not actually replace the old channel entry in the cache.
2204 Affected file lib/silcclient/client_notify.c.
2206 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Fixed a possible crash in silc_packet_send_prepare. It now
2209 assures always that there is enough space in the buffer and
2210 at the tail area of the buffer (for MAC).
2212 Fixed the inbound buffer reallocation in silc_packet_read.
2213 It was old code and did not handle the reallocation correctly.
2216 The affected file is lib/silccore/silcpacket.c.
2218 * Fixed buffer overflow in silc_parse_nickname in the file
2219 lib/silcutil/silcutil.c.
2221 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * make install generates new server keys only if there is not
2226 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2229 Added check that if the NOREPLY is set then we will not send
2230 the away message. This avoids infinite loop of away messages
2231 if both clients are away. The affected file is
2232 lib/silcclient/client_prvmsg.c.
2234 * Fixed client crash if /NICK was given without arguments.
2235 Affected file lib/silcclient/command.c.
2237 * Server does not send the invite list in INVITE command back
2238 to the client if the list was not altered. Added this notion
2239 to the protocol spec as well. Affected file silcd/command.c.
2241 Fixed possible crash in INVITE command by checking the
2242 value of silc_server_get_client_route command.
2244 * Fixed the INVITE notify type handling. The arguments are now
2245 taken in correct order and client does not crash. The affected
2246 file is irssi/src/silc/core/silc-channels.c.
2248 Removed the "Inviting xxx to channel" message from the
2249 client library away and let the application handle it.
2250 Affected file lib/silcclient/command.c. Added that message
2251 to Irssi SILC client's message formats.
2253 * Fixed CMODE command crash in client. It now checks the
2254 amount of arguments correctly and does not crash. The affected
2255 file is lib/silcclient/command.c.
2257 * Do not create new channel automatically in silc_channels_join
2258 but check whether the channel by that name already exists.
2259 Affected file irssi/silc/core/silc-channels.c.
2261 * Do not send the SERVER_SIGNOFF to router if the disconnected
2262 entity was the router. Affected file silcd/server.c.
2264 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2265 SILC client as it was missing from there.
2267 Added the handling of the KICK notify to the Irssi SILC client
2268 as it was missing. Added "you have been kicked" message to
2269 Irssi SILC client's message modules formats.
2271 Added the handing of the KILL notify to the Irssi SILC client
2272 as it was missing. Added the kill message module formats
2275 The affected file is irssi/src/silc/core/silc-channels.c.
2277 * The router did not save the channel mode the server announced.
2278 Affected file silcd/packet_receive.c.
2280 * Fixed a possible crash in INFO command in server. If the
2281 server did not provide the server info it crashed. Affected
2282 file silcd/command.c.
2284 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Fixed the GETKEY command in the server to check also the
2287 global list. Otherwise the GETKEY would not work correctly
2288 in normal SILC server. Affected file silcd/command.c.
2290 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Fixed GETKEY crash, it crashed if the command did not succseed.
2294 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2297 is now real and not just an macro interface to GMP.
2299 Removed the entire GMP from the source tree and imported new
2300 NSS MPI library instead. Reason for removing GMP is that it is
2301 extremely large and compiles extremely slow. The NSS MPI
2302 is only a few files and compiles in less than 10 seconds.
2303 The speed is also about the same as GMP. The MPI is imported
2304 to lib/silcmath/mpi.
2306 If the system has GMP installed we will still use the GMP.
2307 If it is not then the NSS MPI will be compiled.
2309 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Merged a long nickname (127 characters long) crash bugfix from
2312 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2314 * Merged a freed memory reference bugfix from Irssi CVS tree.
2315 Affected file irssi/src/core/commands.c.
2317 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2319 * Added the server's public key sving and verification to the
2320 server when performing the SKE. This was missing and the
2321 remote server's (or router's) public key was accepted without
2322 checking whether we have it previously or trust it at all.
2323 Affected file silcd/protocol.c.
2325 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Check in the silc_server_timeout_remote if protocol is active
2328 and make sure that the protocol's final callback is called so
2329 that all memory if freed. Affected file silcd/server.c.
2331 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * silc_server_whois_send_reply crashed the server if the nickname
2334 was 127 characters long. Affected file silcd/command.c.
2336 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Added sanity check to the silc_server_new_client. If the hostname
2339 is provided inside username then check that the provided hostname
2340 really is the same as the resolved one. If the hostname was not
2341 resolved then check it from the public key. Affected file is
2342 silcd/packet_receive.c.
2344 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2345 if the server disconnected us and the connection is not valid
2346 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2348 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2349 the library to the lib/silcutil/silcutil.[ch].
2351 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Close log file after open. Affected file
2354 lib/silcutil/silclog.c.
2356 * Check whether sock == NULL in silc_client_send_packet and return
2357 if it is. Affected file lib/silcclient/silcclient.c.
2359 * Check rec->entry == NULL in the Irssi SILC Client before
2360 sending the channel message. Affecte file is
2361 irssi/src/silc/core/silc-servers.c.
2363 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2365 * Merged a splitted window bugfix from Irssi CVS tree. The
2366 affected file is irssi/src/fe-text/textbuffer-view.c.
2368 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2369 It did not print nickname.
2371 * Improved the distributions system a bit.
2373 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2375 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2376 irssi/src/fe-text/gui-window.c.
2378 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2379 to in-active server. The affected file is
2380 irssi/src/silc/core/client_ops.c.
2382 * Resolve the client in USERS command reply if the entry does
2383 not have username resolved. The affected file is
2384 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2385 command to WHOIS command to really resolve stuff. The USERS
2386 is not used any more in any critical section so WHOIS can
2387 be used even though it might be slower than IDENTIFY.
2389 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2392 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Changed the protocol API a bit more consistent in the
2395 lib/silccore/silcprotocol.[ch].
2397 * Changed the following headers to ROBODoc format:
2399 lib/silccore/silcpayload.h
2400 lib/silccore/silcprotocol.h
2401 lib/silccore/silcsockconn.h
2403 All core library headers are now formatted.
2405 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Fixed a bug in Irssi SILC client; do not show that you are
2408 server/router operator if you really are not. Affected file is
2409 irssi/src/silc/core/client_ops.c.
2411 * Renamed silc_command_free_payload to silc_command_payload_free.
2412 Affected file lib/silccore/silccommand.h
2414 * Added silcmath.h to include the prototoypes of various routines
2415 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2418 * Changed the following headers to ROBODoc format:
2420 lib/silccore/silcchannel.h
2421 lib/silccore/silccommand.h
2422 lib/silccore/silcid.h
2423 lib/silccore/silcidcache.h
2424 lib/silccore/silcmode.h
2425 lib/silccore/silcnotify.h
2426 lib/silccore/silcpacket.h
2427 lib/silcmath/silcmath.h
2429 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2431 * Added checking to the server code not to start the server if
2432 ciphers and stuff are not configured properly. Affected files
2433 silcd/serverconfig.[h] and silcd/server.c.
2435 * Changed the layout of the header files of the public interfaces
2436 in the SILC libraries. The new layout supports ROBODoc
2437 documentation tool (and some others) so that it is easy to create
2438 a library reference manual. All the other headers and source
2439 code must still follow the CodingStyle document. Also source
2440 code must not include these ROBODoc stuffs, only the headers.
2441 Furthermore, all public interface headers must now be named
2442 by using `silc' prefix, example: silcapi.h, silccipher.h.
2443 Some files were renamed due to this. All the other headers
2444 must not be used as public interfaces. I will update the
2445 CodingStyle document later. Changed following headers, so far:
2447 lib/silcclient/silcapi.h
2448 lib/silccore/silcauth.h
2449 lib/silccore/silcprivate.h
2450 lib/silccrypt/silcdh.h
2452 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Removed silc_client_packet_send_flush from the client library
2457 as it is not needed. Affected file lib/silcclient/client.[ch].
2459 * Added printing of message of unresolved authentication method
2460 to the Irssi SILC client. Added it to the module formats.
2461 Removed the same message from the client library.
2463 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Added new distribution feature, DISTLABEL. Every distribution
2466 can define own preprocessor label that can be used in the
2467 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2468 file distributions, acconfig.h.pre and prepare.
2470 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Added Makefile.defines_int to include the actual definitions
2473 for Makefile.defines.in. Tested the new distribution system,
2474 created distributions and tested installation.
2476 * Added AWAY message printing to the Irssi SILC client. Added
2477 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2479 * Added SCONNECT command to call the SILC's CONNECT command.
2480 Cannot use CONNECT directly since Irssi uses that internally.
2481 Affected file irssi/src/silc/core/silc-servers.c.
2483 Added ACTION local command. It is same as ME command but takes
2484 the channel as mandatory argument.
2486 Rewrote some of the Irssi's help files to suite for SILC
2489 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Added Makefile.defines[.in] that should for now on be included
2492 in all Makefile.am file in the source tree. That file includes
2493 all common compilation definitions for SILC source tree.
2495 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Minor changes to the ./prepare script to change the package
2498 name according the distribution name to the configure.in.
2500 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2502 * Created new distribution system. Added file `distributions'
2503 that defines all the distributions that can be created out of
2504 the SILC source tree. The ./prepare script now reads that
2505 file to determine how to prepare the distributions. The
2506 first argument to the ./prepare is the name of the distribution
2507 and second is the version of the distribution. If given
2508 without arguments it creates the default (toolkit) distribution
2509 with the default version (defined in ./prepare).
2511 All Makefile.am files that are subject to the distributions
2512 are now named as Makefile.am.pre. These are ./Makefile.am
2513 and lib/Makefile.am. Others may be changed later.
2515 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added invite list, ban list, some key management and connection
2518 error message printing to module formats in the Irssi SILC client.
2520 * Added new silc_client_set_away_message to set the away message
2521 that is back to the person who sent private message. The
2522 affected file lib/silcclient/silcapi.h and the
2523 lib/silcclient/client_prvmsg.c.
2525 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Fixed the private message sending in the Irssi SILC client,
2528 added local command KEY to the Irssi SILC client.
2530 Added key management and key agreement message formats to the
2531 irssi/src/fe-common/silc/module-formats.[ch].
2533 Added USERS (alias WHO) printing, server/router operator
2534 indication and LIST command printing to the module formats.
2536 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Fixed channel joining notify handling, cumode notify handling
2539 from Irssi SILC client.
2541 * Added SILC specific module-formats to the Irssi SILC client so
2542 that SILC specific message hilighting, colors etc is possible.
2543 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2545 Added channel mode, channel user mode, actions, notices,
2546 whois and whowas printing to the the module-formats.c.
2548 * Fixed a bug in channel deletion in the server. The channel
2549 is not left to the cache even if the channel founder auth mode
2550 is set when there are no users anymore on the channel. Affected
2551 file silcd/server.c.
2553 * The silc_net_localhost now resolves the entire hostname including
2554 the domain name. Affected file lib/silcutil/silcnet.c.
2556 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Changed the ask_passphrase client operation to be ascynchronous.
2559 It has now a completion callback and a context that the
2560 application must call after it has got the passphrase from
2561 the user. Affected files lib/silcclient/silcapi.h,
2562 lib/silcclient/protocol.c, lib/silcclient/command.c and
2565 Added SilcAskPassphrase callback that the application calls
2566 to deliver the passphrase to the library.
2568 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2569 The public key verification and especially a certificate
2570 verification is asynchronous procedure.
2572 Added new SILC_SKE_STATUS_PENDING status to indicate the
2573 request is pending and a callback will be called to finalize
2576 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2577 indicate that remote end did not send its public key (or
2578 certificate), even though we require it. Added check for this
2579 condition in the SKE. This was a security bug, now fixed.
2581 Defined new SilcSKEVerifyCbCompletion callback that is called
2582 when the verification process is completed.
2584 The affected files lib/silcske/silcske_status.h and
2585 lib/silcske/silcske.[ch].
2587 * Changed the verify_public_key client operation to be async
2588 as well. Defined SilcVerifyPublicKey callback that is used to
2589 indicate the success of the public key verification process.
2591 Changed the server and client to use the new async client
2594 * Changed the Irssi SILC client's internal scheduler to be called
2595 twice as many times as it used to be. As a result the client
2596 should be a bit faster now. Affected file is
2597 irssi/src/silc/core/silc-core.c.
2599 * Added support to Irssi SILC client of asynchronous public key
2600 verification and passphrase inquiry. Affected file is
2601 irssi/src/silc/core/silc-core.c.
2603 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Do not say "You have left channel %s" in client library.
2606 Moved it to the application. Affected files are
2607 lib/silcclient/command.c and silc/client_ops.c.
2609 * Fixed silc_client_get_clients. Command context was not
2610 duplicated and was freed memory in the callback. Affected
2611 file lib/silcclient/idlist.c.
2613 * Do not say "you are now talking..." on JOIN command in the
2614 client library. The appliation must handle it.
2616 * Do not say ".. changed topic to" in command reply in the
2617 client libary. The application must handle it.
2619 * Fixed TOPIC command sending in the client library.
2621 * Fixed a memory leak in silc_client_command_free in the file
2622 lib/silcclient/command.c.
2624 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Imported a modified version of Irssi client to the source tree.
2627 The Irssi will be used to create a new client called
2628 Irssi SILC. Imported to irssi/.
2630 Added silc_core_init_finish function to the Irssi. Affected
2631 file irssi/configure.in.
2633 A lot changes in the Makefile.ams around the irssi tree.
2635 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Do not rehash if the new size is same as the old size of the
2638 hash table, in the silc_hash_table_rehash*. The affected file
2639 lib/silcutil/silchashtable.c.
2641 * Replaced hash_table_del_by_context calls from the server
2642 (when channel->user_list and client->channels) to the
2643 hash_table_del as it is sufficient and faster.
2645 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Added silc_hash_table_list, silc_hash_table_get and the
2648 SilcHashTableList structure to provide an alternative way to
2649 traverse the hash table. The affected files are
2650 lib/silcutil/silchashtable.[ch].
2652 * Changed the server's idlist routines to use the hash table
2653 routines to optimize the code.
2655 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Replaced the client entry's `channel' list and channel entry's
2658 `user_list' list to hash tables for optimized lookup. Changed
2659 the code to use the hash table interface around the code.
2660 Affected file lib/silcd/idlist.[ch].
2662 * Added `auto_rehash' boolean argument to the function
2663 silc_hash_table_alloc to indicate whether the hash table should
2664 auto-rehash when it thinks is appropriate time. It will
2665 increase the hash table size if the there is twice as much
2666 entries in the table than the size of the table, and will
2667 decrease the size if there are twice as less entries than
2668 the size of the table.
2670 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2674 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2676 * silc_idcache_purge_by_context deletes the entry now by context
2677 as it is supposed to do. Affected file lib/silccore/idcache.c.
2679 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2680 client is not anymore valid (WHOWAS givens the info) and not
2681 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2683 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Removed the `data' and `data_len' arguments from the ID Cache
2686 interfaces and added `name' argument. ID Cache does not handle
2687 anymore the binary data only a names associated with given ID.
2689 * When hashing a Client ID with silc_hash_id the entire ID is
2690 not hashed anymore, instead only the hash of the Client ID is
2691 hashed. This way we can access the Client ID from the cache
2692 with Client ID but with the hash of the ID (which is a hash of
2693 the nickname) as well without any difference in performance.
2695 Added also silc_idcache_find_by_id_one_ext to do one on one
2696 searching when we have the actual ID. Added also function
2697 silc_hash_client_id_compare. The affected files are
2698 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2700 * When hashing the name associated with a ID it is always done
2701 in lowercase. This way we can access the cache without worrying
2702 about case-sensitivity, even though, for example nicknames are
2705 * Fixed a bug in server with channel message sending. It put
2706 wrong ID type as destination ID. The affected file
2707 silcd/packet_send.c.
2709 * silc_idcache_del_by_context now deletes from all hash tables
2710 by context. Affected file lib/silccore/idcache.c.
2712 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2714 * Changed the client library to use the new ID Cache interface.
2715 Changes around the source tree.
2717 * Added silc_hash_table_rehash_ext to rehash with specific
2718 hash function. Affected file lib/silcutil/silchashtable.[ch].
2720 * Added silc_hash_string_compare to compare two strings in the
2721 hash table. Affected file lib/silcutil/silcutil.[ch].
2723 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Added new function silc_idcache_del_by_context into the
2726 lib/silccore/idcache.[ch].
2728 * Changed the server's ID list routines to use the new ID Cache
2729 interface. Changes around the source tree.
2731 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Added silc_hash_table_del[_by_context]_ext functions in to the
2734 lib/silcutil/silchashtable.[ch].
2736 Removed silc_hash_table_find_all* routines and added new
2737 silc_hash_table_find_foreach to replace them.
2739 Added silc_hash_table_replace_ext function as extended
2740 replacing function. Separated the simple hash table interface
2741 from the extended hash table interface in the file
2742 lib/silcutil/silchashtable.h.
2744 * Fixed minor bugs and changed it to use some of the new
2745 hash table functions in lib/silccore/idcache.c
2747 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Added new function silc_hash_table_find_all to return all keys
2750 in the hash table by the specified key. As the hash table is
2751 collision resistant it also makes it possible to have several
2752 duplicate keys in the hash table. This function may be used to
2753 find all of the keys from the hash.
2755 Added user_context arguments to the SilcHashFunction,
2756 SilcHashCompare and SilcHashDestructor to deliver user specified
2759 Added new fuctions silc_hash_table_find[_all]_ext to do
2760 extended lookup with specified hash and compare functions and
2761 specified user contexts.
2763 Added new function silc_hash_table_add_ext to add the key
2764 with specified hash function and user context.
2766 Added new function silc_hash_table_foreach to traverse all
2767 entrys in the hash table. Added SilcHashForeach callback
2770 Added new function silc_hash_table_del_by_context to delete
2771 the entry only if the context associated with the key matches.
2773 Affected files are lib/silcutil/silchashtable.[ch].
2775 * Removed silc_hash_[server/client/channel]_id and added just
2776 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2777 silc_hash_id_compare to compare two ID's using as the hash table
2778 comparison function. Added also silc_hash_data to hash
2779 binary data and silc_hash_data_compare to compare it.
2781 * Removed silc_idlist_find_client_by_hash as it is not needed
2782 anymore. Affected file silcd/idlist.[ch].
2784 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2785 to use internally the SilcHashTable. The new ID Cache is a lot
2786 faster than the old one. Some of the ID Cache interface was also
2787 rewritten and obsolete and stupid functions were removed.
2789 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added entry_count field to the SilcHashTable to keep the number
2792 of the entries in the table. Implemented the function
2793 silc_hash_table_rehash. Added new function
2794 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2796 Fixed a minor bug in silc_hash_table_free.
2798 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2799 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2800 into the lib/silcutil/silcutil.[ch].
2802 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Implemented a collision resistant hash table into the
2805 lib/silcutil/silchashtable[ch]. See the header and the source
2806 for the SilcHashTable API.
2808 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Merged dotconf version 1.0.2 into lib/dotconf.
2812 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Do not compile anything in lib/silcsim/* if the SIM support
2815 is not enabled. The tree should now compile without problems
2818 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2820 * Compiled the SILC under cygwin. Compiled and tested briefly
2821 without problems. More tests needed. The SIMs didn't compile
2824 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2826 * Fixed possible crash in silc_get_username in the
2827 lib/silcutil/silcutil.c.
2829 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Fixed a va_arg in silc/client_ops.c.
2833 * Oops, RC5 routines were named AES and caused some problems
2834 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2836 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Added new SilcIDIP structure into the lib/silccore/id.h and
2839 replaced the old `ip' fields from all SILC ID's to that type.
2840 This is a step towards IPv6 support.
2842 The silc_id_get_len takes now the ID as an extra argument.
2843 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2844 both IPv4 and IPv6 based ID's.
2846 The affected files are lib/silccore/id.[ch] and other files
2847 around the tree using these routines.
2849 * Removed the ID length arguments in server from various
2850 silc_server_send_notify_* routines -> they are not needed
2853 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Fixed memory leak in silc_encode_pem_file in the file
2856 lib/silcutil/silcutil.c.
2858 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Check minor version as well in the SKE. Affected files are
2861 silcd/protocol.c and lib/silcclient/protocol.c.
2863 * Added --identifier option to the server so that an identifier
2864 can be when creating the public key for the server. Affected
2865 file is silcd/silcd.c.
2867 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2868 lib/silccrypt/silcpkcs.c.
2870 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Register default ciphers and stuff when using -C option with
2873 the server. Affected file sildc/silcd.c.
2875 * Put back the servers public key filename format, it is better
2876 than the new one. For now, the client keys are saved with the
2877 new filename format. The affected file silc/client_ops.c.
2879 * Implemented the Cipher API for the rest of the ciphers that
2880 did not implement it or implemented it the wrong way.
2882 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Register default ciphers and stuff when using the -S option
2885 in the client. Affected file silc/silc.c. Same also when
2886 creating new key pair with -C option.
2888 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Fixed the silc_verify_public_key client operation function to
2891 save the public keys differently. The fingerprint is now
2892 used as filename and not the hostname. This way also the
2893 client keys are saved uniquely and not with hostnames. The
2894 affected file is silc/client_ops.c.
2896 * Trimmed the silc_hash_fingerprint function to remove extra
2897 whitespaces from the end of the fingerprint. The affected
2898 file is lib/silccrypt/silchash.c.
2902 * Added silc_cipher_register_default function to register all
2903 default ciphers. It can be used when configuration files
2904 does not exist and the application does not want any specific
2905 ciphers in any specific order.
2907 The SilcDList is now used as silc_cipher_list dynamically
2908 allocated cipher list. Removed the static list all together
2909 and now all ciphers must be allocated to the dynamic list.
2910 The silc_cipher_alloc routine was changed to check only the
2913 All silc_cipher_* routines that used to return int returns
2916 The affected files lib/silccrypt/silccrypt.[ch].
2918 * The same thing was done to silc_hash_* as for silc_cipher_*
2919 routines. Affected files lib/silccrypt/silchash.[ch].
2921 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2922 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2923 Added also silc_pkcs_[un]register[_default] functions.
2924 Removed the data_context from the PKCS API.
2926 * Added silc_hmac_register_default function to register default
2927 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2928 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2929 to unregister all hmacs at once.
2931 * Register the default ciphers, hash functions, PKCSs and HMACs
2932 if client's configuration file does not exist. The affected
2935 * The client did not load the hash functions from the SIM
2936 modules at all. Added support for this. Affected file is
2937 silc/clientconfig.c.
2939 * When decoding public key with silc_pkcs_public_key_decode, check
2940 the supported algorithm only if PKCS are registered. Affected
2941 file lib/silccrypt/silcpkcs.c. The same was done with the
2942 silc_pkcs_private_key_decode.
2944 * Fixed the SILC List routines to keep the list always in order.
2945 It used to change the list's order when traversing the list but
2946 not it preserves the order. Affected file lib/trq/silclist.h.
2948 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Added the client library to use the SilcSocketConnection's
2951 reference counter (by silc_socket_dup) to prevent the bug that
2952 the socket object may be freed underneath async operation.
2954 * The name resolv library checking fixes in the configure.in.pre.
2957 * Created new version of the protocol drafts for future
2958 development. The -03 drafts are the ones that will be changed
2959 in the trunk now and the -02 will remain as they are.
2961 * Send list of CUMODE notifys to the router when announcing
2962 the channel users to the router. Affected file silcd/server.c.
2963 If the router receiving channel founder CUMODE for a channel
2964 that already has channel founder it will send CUMODE notify
2965 to the sender to remove the channel founder rights from the
2966 announced client. Affected file silcd/packet_receive.c.
2968 * The CUMODE notify may now use Server ID as well as the entity
2969 who changes the mode. Updated protocool specs.
2971 * Updated INSTALL and README files.
2973 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2975 * New web pages in the http://silc.pspt.fi. The pages was
2980 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2982 * Implemented the [DenyConnectin] config section in the server.
2983 Added silc_server_config_denied_conn to check whether incoming
2984 connection is denied. Affected file silcd/serverconfig.[ch].
2986 * Do not check the ports when checking the incoming configuration
2987 data if the port is 0, meaning any. Affected file is
2988 silcd/serverconfig.c.
2990 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Fixed buffer overflow in silc_string_compare in the file
2993 lib/silcutil/silcutil.c.
2995 * Fixed double free in silc_server_command_leave in the file
2998 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Fixed the version checking in the server. Affected file is
3003 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Fixed the configuration data fetching when accepting new
3006 connections in the server. Affected file silcd/server.c.
3008 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3010 * Added `sender_entry' argument to the function
3011 silc_server_packet_relay_to_channel so that we can check
3012 whether some destination actually belongs to the same route
3013 the sender belongs (ie, we must not resend the packet to the
3014 sender). Affected file silcd/packet_send.[ch].
3016 * Added `servername' field to the SilcClientEntry in the server
3017 to hold the name of the server where client is from. Affected
3018 file is silcd/idlist.h.
3020 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3022 * Moved the channel message encrypting in the router betwen
3023 router connections from silc_server_channel_message to the
3024 silc_server_packet_relay_to_channel since we want to check
3025 whether we have anybody channel before encrypting anything.
3026 Affected files silcd/packet_[receive/send].c.
3028 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Fixed the [AdminConnection] server config section to support
3031 multiple entries. Affected file silcd/serverconfig.c.
3033 * Added support into the server to check the validity of the
3034 incoming connection before executing any KE or authentication
3037 * The connection configuration is now saved to the KE and
3038 connection auth protocol contexts and not fetched anymore in
3039 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3041 * The local hosts listenning address and port is also resolved
3042 now when starting the server. We want to have the socket object
3043 to include the real address and port for the listener. Added
3044 new function silc_net_check_local_by_sock into the files
3045 lib/silcutil/silcnet.[ch].
3047 * Fixed a broadcast bug in server -> do not broadcast if we
3050 * Fixed a routing bug. Do not route broadcast packets ever.
3051 Broadcast packets must be processed always and not routed since
3052 they may be destined to some other host than yourself and thus
3053 would get routed without no good reason. Affected file is
3056 * Added function silc_server_config_is_primary_route to check
3057 whether primary router connection has been configured (a router
3058 configuration that we are initiating). If there is not, we
3059 will assume that there is only two routers in the SILC network
3060 and we will use the incoming router connection as our primary
3061 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3063 * Changed the order of the broadcasting. Broadcast _after_ the
3064 packet has been processed not before. Affected file is
3067 * Fixed a [ClientConnection] parsing bug. The port was never
3068 parsed correctly thus resulting to port 0. Affected file
3069 silcd/serverconfig.c.
3071 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3072 argument and did not set the broadcast packet flag. Affected
3073 file silcd/packet_send.c. Fixed same bug in the function
3074 silc_server_send_notify as well.
3076 * If we receive NEW_ID packet for our own ID in the server, ignore
3079 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Removed the nickname from the Private Message Payload.
3084 Updated the code and the protocol specs.
3086 * Updated protocol specs for submitting to the IETF.
3088 * Tweaked the Random Number Generator a bit. Affected file
3089 lib/silccrypt/silcrng.c. Exported a new function
3090 silc_rng_[global]_add_noise which can be used to add more
3093 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * Do not parse packets with different timeout when protocol
3096 is active -> may cause problem with rekey. Affected file
3099 * When server receives signoff notify it must not create
3100 new channel key if the client is on any channels since the
3101 sender of the signoff notify will create it.
3103 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Added printing of error messages during SKE protocol from the
3106 failure packet sent by server during SKE. Affected file
3109 * Removed the client's failure_callback handling with timeout
3110 and handle it immediately when received.
3112 * The SKE library returned wrong type in SUCCESS and FAILURE
3113 packets. They must be 32 bit MSB not 16 bit MSB.
3115 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Ok, rewrote the logic of the re-key and now it seems to work.
3118 I tested it on high traffic with frequent re-keys without
3119 problems. Added hmac_receive (and renamed hmac to hmac_send)
3120 in SilcClientConnection in lib/silcclient/client.h and
3121 in SilcIDListData in silcd/idlist.h. Also, removed the
3122 SilcPacketParserContext's cipher and hmac fields as they are
3123 not needed anymore and actually caused some problems when
3124 the ciphers and hmac's changed underneath the packet parser.
3126 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * If re-key protocol is active then process the incoming packets
3129 synchronously since we must assure that icoming packets encrypted
3130 with the old key is processed before the new keys is set to
3131 use. This is true other packets than for REKEY packets.
3132 Affected file silcd/server.c. The same was done to client library
3133 as well, affected file lib/silcclient/client.c.
3135 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Fixed bug in client and server to accept the force send if
3138 the packet is send from silc_[server/client]_packet_process
3139 function. Otherwise the packets are never delivered, oops.
3141 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3143 * Disable force sending of packets when REKEY protocol is active.
3144 We must assure that no packet is sent directly when rekey is
3145 performed. All packets must be sent through packet queue.
3146 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3147 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3148 function is silc_[server/client]_packet_send_real to check
3151 * Replaced the SIM paths from example config files to
3152 /usr/local/modules. Also, make install creates now
3153 /usr/local/silc/logs directory to hold all the SILC server
3156 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Made the configure.in.pre work on Solaris. Patch by salo.
3160 * Made all ciphers compatible with non-x86 machines. Defined
3161 CBC mode macros into lib/silccrypt/ciphers_def.h.
3163 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Fixed the make install.
3167 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * When MAC computation fails the silc_packet_decrypt returned 0
3170 even though it was supposed to return -1. Fixed this. The
3171 affected file is lib/silccore/silcpacket.c.
3173 * Do not replace the config files in /etc/silc (in make install)
3174 if they already exist. Affected file ./Makefile.am.
3176 * Do not send re-key packets immediately but through packet queue.
3177 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3179 * Changed silc_net_check_host_by_sock to return FALSE if the
3180 IP/DNS could not be resolved. Though, it returns the IP address
3181 now even if it could not resolve it (but returns also FALSE).
3182 Affected file lib/silcutil/silcnet.[ch].
3184 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added silc_pkcs_decode_identifier to decode the public key's
3187 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3188 Added also silc_pkcs_free_identifier. Added also new context
3189 SilcPublicKeyIdentifier.
3191 * Added -S option to the silc client. It is used to dump the
3192 contents of the specified public key file.
3194 * Changed the PKCS api to return the public key length when
3195 setting the public key.
3197 * Fixed a fatal bug in the public and private key file loading.
3198 Affected file lib/silccrypt/silcpkcs.c.
3200 * Execute the packet parsing for client with zero (0) timeout
3201 if the protocol is active. Affected file silcd/server.c.
3203 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Made the key generation options to the silcd program. Added
3206 -C option, equivalent to client's option.
3208 * Added new [ServerKeys] config section to the server. It
3209 configures the server's public and private key.
3211 * Defined generic Public Key Payload into the protocol
3212 specification to send specific type of public keys and
3215 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3216 public key or certificate.
3218 * Implemented the GETKEY command to the server and to the
3219 client library and on user interface.
3221 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Made preliminary `make install' work.
3225 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added SilcServerRekey context into silcd/idlist.h.
3229 * Added the PFS support as defined in the specification to the
3230 SKE protocol. Affected files lib/silcske/*.c.
3232 * Added `ske_group' field to the SilcServerRekey context to hold
3233 the number of the SKE group that is used with PFS in re-key.
3234 Affected file silcd/idlist.h.
3236 * Added PFS re-key support to the server. Affected file is
3239 * Added silc_protocol_cancel to cancel execution of the next
3240 state of the protocol. Affected file is
3241 lib/silccore/silcprotocol.[ch].
3243 * Added the re-key support with and without PFS to the client
3244 library. Re-key is performed once in an hour, by default.
3246 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3247 Added silc_client_rekey_callback and silc_client_rekey_final.
3248 Affected files are lib/silcclient/protocol.[ch] and
3249 lib/silcclient/client.[ch].
3251 * Removed the `hmac_key' and `hmac_key_len' fields from the
3252 SilcClientConnection structure; not needed. Affected file is
3253 lib/silcclient/client.h.
3257 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Do not ask whether user wants to use the negotiated private key
3260 for private messages, just use it. Affected file is
3261 silc/local_command.c.
3263 * Added `send_enc_key' and `enc_key_len' fields to the
3264 SilcIDListData structure since they are needed in the re-key
3265 phase. Affected file is silcd/idlist.[ch].
3267 * Implemented the simple re-key protocol into the server.
3268 Affected files silcd/server.c and silcd/protocol.[ch]. The
3269 re-key will be performed once in an hour, by default.
3271 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3272 Added silc_server_rekey, silc_server_rekey_callback and
3273 silc_server_rekey_final.
3275 * Removed Tunneled flag from the protocol. Updated the code
3276 and the specifications.
3278 * Adde `pfs' field to the SilcIDListData to indicate whether
3279 the PFS is to be performed in the re-key. Affected file is
3282 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3285 int64 of at least the xintXX size. If void * is less that 4
3286 bytes uint32 * will be used. Defined bool as boolean.
3288 * Changed _ALL_ unsigned long and unsigned int to uint32,
3289 unsgined short to uint16 in the source tree.
3291 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3292 not handle clients that has entry->data.registered == FALSE.
3293 They are not in the network anymore. Affected file is
3296 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Implemented the sending of the SERVER_SIGNOFF notify in the
3299 server. Affected file is silcd/server.c.
3301 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3302 Added also silc_notify_payload_encode_args into the
3303 lib/silccore/silcnotify.[ch].
3305 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3306 Affected file silcd/packet_receive.c.
3308 * Implemented the SERVER_SIGNOFF notify handling in the client
3309 library. Affected file lib/silcclient/client_notify.c. Also,
3310 implemnted the printing of the SERVER_SIGNOFF info to the
3311 application. Affected file silc/client_ops.c.
3313 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3314 if the deleting was successful. Affected file silcd/idlist.[ch].
3316 * Added support for public key authentication in the connection
3317 authentication protocol in the client library. Affected file
3318 lib/silcclient/protocol.c.
3320 * Changed the server's silc_idlist_get_clients_by_* interface
3321 to support already allocated array so that new entries may be
3322 added to pre-allocated array. Affected file silcd/idlist.[ch].
3323 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3324 and command replies.
3326 * All command reply functions in the server now calls the
3327 pending command callback even if error occured. This way the
3328 error will be delivered to the client as well. Affected files
3329 silcd/command.c and silcd/command_reply.c.
3331 * Fixed INFO command to return local server's info if no server
3332 was provided. Affected file lib/silcclient/command.c.
3334 * Removed RESTART command for good. Updated the code and the
3337 * Rewrote parts of the task system. It is a bit simpler now.
3338 Removed unsued task priorities. The affected files are
3339 lib/silcutil/silctask.[ch].
3341 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Moved the USERS printing from the library to the application.
3344 Affected files lib/silcclient/command.c and silc/client_ops.c.
3346 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Added channel key re-key support. The re-key is perfomed
3351 only by the router and is done once in an hour. Added `rekey'
3352 field to the SilcChannelEntry in the server. Affected files
3353 silcd/server.c and silcd/idlist.h.
3355 * Added silc_task_unregister_by_context into the file
3356 lib/silcutil/silctask.[ch].
3358 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Added SILC_UMODE_GONE mode to indicate when the client is not
3361 present in the SILC network. Added also support to the local
3362 command AWAY that will set this mode. Added support of showing
3363 "xxx is gone" in WHOIS command. The USERS command shows the
3364 gone status as well.
3366 * Fixed setting server and router operator privileges in the
3367 server's UMODE command. Affected file silcd/command.c.
3369 * Merged the SKE KE1 and KE2 payloads into one payload. The
3370 new KE payload is equivalent to the old KE2 payload.
3372 Cleaned up the SKE Start Payload parsing. It now uses the
3373 simple buffer unformatting to do the parsing. A lot faster
3376 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3377 to the SKE that is used to indicate whether both of the SKE
3378 parties should perform authentication. By default only the
3379 responder performs authentication. By setting this flag also
3380 the initiator must do authentication. By default it is unset
3381 since in normal SKE case, client to server connection, only
3382 the responder should do authentication. When doing SKE between
3383 two clients both should perform authentication. Updated the
3384 code and the protocol specs.
3386 * A little fix to IDENTIFY command in the server. Search the
3387 client first by hash not nickname. Affected file is
3390 * Fixed the silc_client_close_connection to support closing
3391 the client to client connections wihtout deleting too much
3392 data. Affected file lib/silcclient/client.c.
3394 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3395 are received if protocol used to be active but is not anymore
3396 the application would crash due to NULL pointer dereference.
3397 Affected files silcd/server.c and lib/silcclient/client.c.
3399 * Added `hash' field to the SilcClientConnection to include
3400 the hash function negotiated in the SKE protocol.
3402 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3403 to set the channel founder authentication data. A client can
3404 claim the founder rights later by providing the authentication
3405 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3406 This way the channel founder can regain the channel founder
3407 privileges even it is left the channel. This works only on
3408 local server and the client must be connected to the same
3409 server to be able to regain the founder rights. Updated the
3410 protocol specs accordingly.
3412 Added support to the CMODE command in the client to set the
3413 founder auth data. Read the README to see how to set it.
3415 Added support to the CUMODE command to claim the founder
3416 rights. Read the README to see how to do it.
3418 Added support for the founder authentication to the Channel
3419 Entry in the server. Affected file silcd/idlist.h.
3421 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3422 server's CMODE command. Affected file silcd/command.c.
3424 * Added the following new functions into lib/silccore/silcauth.[ch]:
3425 silc_auth_get_method and silc_auth_get_data.
3427 * The server now saves the remote hosts public key to the
3428 SilcIDListData pointer. Affected file silcd/protocol.c.
3430 * The normal server now does not remove the channel entry from
3431 the cache if the founder authentication data is set. It used
3432 to remove it if the founder was the last one on the channel on
3433 the server and left the channel. The auth data is saved and
3434 if the channel is re-joined later the old entry is used with
3435 the old auth data. Affected files silcd/command_reply.c and
3438 * Removed the `pkcs' field from the SilcIDListData structure
3439 in the server; it is not used. Affected file silcd/idlist.h.
3441 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Fixed packet processing on slow links. Partial packets were
3444 never re-processed because the incoming data buffer was cleared
3445 by the application. Application must not directly clear the
3446 sock->inbuf, the packet processing routines handle it. Fixed
3447 this in client library and in server.
3449 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3451 * Fixed the WHOIS and IDENTIFY send reply function to really
3452 check whether to send list or just one entry. Affected file
3455 * Cleaned up the LEAVE command's channel key distribution. The
3456 affected file silcd/command.c.
3458 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3459 can enforce the channel mode as well. In that case the ID
3460 includes the ID of the server. The code now enforces the
3461 mode change if the router have different mode than the server.
3463 * The notify client operation with CMODE_CHANGE notify can now
3464 return NULL client_entry pointer if the CMODE was not changed
3465 by client. Application must check for this.
3467 * Added <Server ID> argument to INFO command to support server
3468 info fetching by Server ID.
3470 * Added silc_server_announce_get_channel_users to get assembled
3471 packets of channel users of the specified channel. Affected
3472 file silcd/server.[ch].
3474 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3475 was freed underneath the ID Cache.
3477 * Re-announce clients when the server received CHANNEL_CHANGE
3478 notify from the router. Affected file silcd/packet_send.c.
3480 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3483 crashed since it did not handle the fact that there is no cipher
3484 called "3" and didn't check the error condition. Now fixed.
3486 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3487 flag. It can be used to send message requests.
3489 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Implemented the RESTART command in the client.
3493 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3494 notice type messages. Added notice printing to the user
3497 * The channel keys are not re-generated if the channel's mode
3498 is PRIVKEY, ie private key on the channel exists. Affected
3499 files silcd/server.c and silcd/command.c.
3501 * Fixed a little bug in channel message delivery when channel
3502 private keys are set in the server. Affected file is
3503 silcd/packet_send.c.
3505 * Changed the setting on channel->on_channel = TRUE from the
3506 silc_client_save_channel_key to the JOIN command reply. The
3507 key payload is not received if the private channel key is set.
3508 Affected file lib/silcclient/command_reply.c and the
3509 lib/silcclient/client_channel.c.
3511 * When the CMODE_CHANGE notify is sent and the channel private
3512 key mode is removed the channel key must be re-generated in
3513 other cells as well. Added this support for the router in the
3514 silcd/packet_receive.c.
3516 * Added new local command NOTICE to send notice message on
3517 channel. Affected file silc/local_command.[ch].
3519 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Added new local command ME to the client. It is used to send
3522 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3523 some action. Affected file silc/local_command.[ch].
3525 * Changed channel_message and private_message client operations
3526 to deliver the message flags to the application. Added also
3527 the `flags' arguments to the silc_client_send_channel_message
3528 and silc_client_send_private_message functions. Affected file
3531 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Redefined the Private Message Payload to support private message
3534 keys and to support the new private message flags. Updated
3535 the protocol specs. Flags makes it possible to have for example
3536 CTCP style messages.
3538 * Added new type SilcPrivateMessagePayload and defined an API
3539 for it in the lib/silcclient/silcprivate.[ch].
3541 * Tested private message private keys successfully. Tested the
3542 private message key set, unset and list commands with the new
3545 * Redefined the Channel Message Payload to include the channel
3546 message flags (equal with private message flags) to support
3547 for example CTCP style messages.
3549 * Defined some of the message (for channel and private message)
3550 flags. Updated the protocol specs and added the flags to the
3551 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3553 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added SilcKeyAgreementStatus type to the key agreement routines
3556 to indicate the current status and error if one occured.
3557 The status types are defined in the lib/silcclient/silcapi.h.
3559 * Added new local command KEY that is used to set and unset private
3560 keys for channels, set and unset private keys for private messages
3561 with remote clients and to send key agreement requests and
3562 negotiate the key agreement protocol with remote client. The
3563 key agreement is supported only to negotiate private message keys,
3564 it currently cannot be used to negotiate private keys for channels,
3565 as it is not convenient for that purpose.
3567 * Fixed a minor pending callback setting bug in the function
3568 silc_client_get_client_by_id_resolve, now the function works.
3569 Affected file lib/silcclient/idlist.c.
3571 * Added function silc_net_get_local_port to get local bound
3572 port by socket. Added to lib/silcutil/silcnet.[ch].
3574 * Added `sockets' and `sockets_count' fields to the SilcClient
3575 object. They hold the sockets of the listenning sockets in
3576 the client. Listenning sockets may be for example the key
3577 agreement server. Affected file lib/silcclient/client.[ch].
3578 Added functions the silc_client_add_socket and the
3579 silc_client_del_socket. They are exported to the application
3582 * Added ~./silc/clientkeys to support other client's public keys.
3584 * Renamed verify_server_key client operation to verify_public_key
3585 and added one argument to indicate the type of the connection
3586 (server, client etc.).
3588 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * Added silc_server_connection_auth_request to handle the
3591 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3592 silcd/packet_receive.[ch].
3594 * Added silc_server_send_connection_auth_request into the
3595 silcd/packet_send.c to send the connection auth request packet.
3597 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3600 * Fixed the public key authentication in responder side in the
3601 server. The `auth_data' pointer includes the SilcPublicKey
3602 not the path to the public key. Affected file silcd/protocol.c.
3604 * Implemented the public key authentication in the initiator side
3605 in the server. Affected file silcd/protocol.c.
3607 * Removed the [RedirectClient] config section from the server
3608 configuration. Is not needed and I don't want to implement it.
3610 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Cleaned up the CMODE command in the server. It now works
3613 correctly and supports all the modes defined in the protocol.
3614 Affected file is silcd/command.c.
3616 * Added `hmac_name' field to the SilcChannelEntry in the server
3617 to hold the default HMAC of the channel. It can be set when
3618 creating the channel (with JOIN command). Affected files
3621 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3622 type to indicate the change of the current cipher and hmac
3623 on the channel. Client can safely ignore the <cipher> argument
3624 (if it chooses to do so) since the CHANNEL_KEY packet will
3625 force the channel key change anyway. The <hmac> argument is
3626 important since the client is responsible of setting the new
3627 HMAC and the hmac key into use.
3629 * Fixed the CMODE command in the client library as well.
3631 * Tested CMODE command in router environment successfully.
3633 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Show the version of the remote client (or server) when connecting
3636 to the server. It is logged to the log file. Affected file
3637 is silcd/protocol.c.
3639 * Fixed the KILLED notify handling in the client library. The
3640 client must be removed from all channels when receiving the
3643 Also, do not remove the client entry when giving the KILL
3644 command but when the KILLED notify is received.
3646 * Removed silc_idlist_find_client_by_nickname from the server.
3647 Not needed anymore. Affected files silcd/idlist.[ch].
3649 * Implemented the CHANNEL_CHANGE notify type handling to the
3650 server. Affected file silcd/server.c.
3654 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Added silc_server_send_notify_invite to send the INVITE
3657 notify between routers.
3659 * Implemented the INVITE command correctly to the server.
3661 * Implemented the INVITE notify type handling in the server.
3663 * Implemented the INVITE command to the client library and on the
3666 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Added function silc_server_get_client_resolve to find the
3669 client entry by ID from all ID lists and then resolve it
3670 (using WHOIS) if it cannot be found. Affected file is
3673 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Implemented the BAN command to the client library.
3677 * The JOIN command in the server now checks the invite list
3680 * Changed the silc_command_reply_payload_encode_va and the
3681 silc_command_payload_encode_va to support that if argument is
3682 NULL it ignores and checks the next argument. Affected file
3683 lib/silccore/silccommand.c.
3685 * Added silc_server_send_notify_ban to send the BAN notify
3686 type between routers.
3688 * Chaned the silc_notify_payload_encode to support that if
3689 argument is NULL it ignores and checks the next argument.
3690 Affected file lib/silccore/silcnotify.c.
3692 * Tested ban lists in router environment successfully.
3694 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Implemented BAN command to the server, in silcd/command.[ch].
3698 * Removed the BAN and INVITE_LIST modes from the CMODE command
3701 * Added function silc_string_match to regex match two strings.
3702 Affected files lib/silcutil/silcutil.[ch].
3704 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Redefined parts of the SilcChannelEntry in the server to support
3707 the new ban and invite lists.
3709 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Redefined the INVITE command. The same command can be used to
3712 invite individuals to the channel but also to manage the invite
3713 list of the channel (to add to and remove from the invite list).
3714 Updated the protocol specs.
3716 * Added new command SILC_COMMAND_BAN that can be used to manage
3717 the ban list of the channel. Updated the protocol specs.
3719 * Removed the channel modes: the SILC_CMODE_BAN and the
3720 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3721 in the CMODE command. The equivalent features are now available
3722 using INVITE and BAN commands. Updated the protocol specs.
3724 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3725 in the network about change in the current ban list. The notify
3726 type is not used by the client.
3728 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3729 support the invite lists.
3731 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Added new function silc_string_regexify that converts string
3734 including wildcard characters into regex string that can
3735 be used by the GNU regex library. Added into the file
3736 lib/silcutil/silcutil.[ch].
3738 Added silc_string_regex_combine to combine to regex strings
3739 into one so that they can be used as one regex string by
3740 the GNU regex library. Added into the file
3741 lib/silcutil/silcutil.[ch].
3743 Added silc_string_regex_match to match two strings. It returns
3744 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3746 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Imported GNU regex to the soruce tree into lib/contrib.
3749 Fixed some compiler warning from the regex.c.
3751 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Fixed MOTD command in the server to work in router environment.
3755 * Fixed the MOTD command in the client library to support
3756 the server argument in the command.
3758 * Added `nickname_len' argument to the silc_idlist_add_client
3759 in the server, as the `nickname' argument may be binary data
3762 * Added silc_idlist_get_channels to return all channels from
3765 * Implemented LIST command to the server. Affected file is
3768 * Implemented the LIST command to the client library and on the
3771 * Added [<user count>] argument to the LIST command reply.
3772 With private channels the user count is not shown.
3774 * Updated TODO and README.
3776 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * The client entry's data.registered must be TRUE even with
3779 global client entry on global client list. The data.registered
3780 is used to check whether the client is anymore in the network,
3781 for example with WHOWAS command so it must be valid.
3783 * Fixed the WHOWAS command in the server. It now actually works
3784 in router environment. Added function into silcd/command_reply.c
3785 silc_server_command_reply_whowas_save.
3787 * Added silc_idlist_purge function to the silcd/idlist.c
3788 to periodically purge the ID Cache.
3790 * Fixed INFO command in the server. It works now in router
3791 environment. Added <server name> argument to the INFO command
3792 reply. Updated the protocol specs.
3794 * Fixed minor bug in silc_idcache_purge to not purge if the
3795 expire value is zero.
3797 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3798 they were buggy because of the WHOWAS information.
3800 * Fixed local command MSG to handle the async resolving of
3801 the remote client properly. It used to fail the first MSG.
3802 Affected file silc/local_command.c.
3804 * Added `data_len' field to SilcIDCache context.
3806 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Update TODO. Todo in commands in the server.
3810 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3813 used by routers as broadcast packet to inform other routers
3814 about the changed user mode.
3816 Implemented the notify handling in the server. Affected file is
3817 silcd/packet_receive.c. Added the function
3818 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3820 * Added new generic Channel Payload and deprecated the New Channel
3821 Payload. The New Channel Payload is now the generic Channel
3824 * Added new argument `mode' to the silc_server_send_new_channel
3825 as it is required in the Channel Payload now.
3827 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3828 and created a new and real SilChannelPayload to represent the
3829 new generic Channel Payload. Implemented the encode/decode
3830 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3832 * Added silc_server_get_client_channel_list to return the list
3833 of channels the client has joined for WHOIS command reply.
3834 Affected file silcd/server.[ch].
3836 * Implemented the channel list sending in the WHOIS command reply
3837 in server and in the client.
3839 Implemented the channel list displaying on the user interface
3840 as well. Affected file silc/client_ops.c.
3842 * Added silc_channel_payload_parse_list to parse list of Channel
3843 Payloads. It returns SilcDList list of SilcChannelPayloads.
3844 Client for example can use this function to parse the list of
3845 channels it receives in the WHOIS command reply. The caller
3846 must free the list by calling silc_channel_payload_list_free.
3847 Affected files lib/silccore/silcchannel.[ch].
3849 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Added one new argument <user mode> to the WHOIS command reply
3852 to return the mode of the user in SILC. Updated the protocol
3855 Implemented it to the server and client.
3857 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Fixed the mode printing on the user interface on joining.
3860 Affected file silc/client_ops.c.
3862 * Implemented the UMODE command and user modes in general to the
3863 client library and to the user interface.
3865 * Implemented the UMODE command to the server.
3867 * The server now sends UNKNOWN_COMMAND error status if client sends
3868 unknown command. Affected file silcd/command.c.
3870 * All server commands now handle the command identifier the right
3871 way when sending the command reply to the client. The client can
3872 use to identify the command replies with the identifier.
3874 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added silc_server_get_client_route to resolve the route to
3877 the client indicated by the client ID. Affected file is
3880 * Added silc_server_relay_packet as general function to relay
3881 packet to arbitrary destination. This deprecates functions
3882 like _send_private_message_key, _relay_notify etc. Affected
3883 file is silcd/packet_send.[ch].
3885 Removed silc_server_send_key_agreement,
3886 silc_server_send_private_message_key and
3887 silc_server_packet_relay_notify functions from the file
3888 silcd/packet_send.[ch].
3892 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3893 server. Affected file silcd/packet_receive.[ch].
3895 * Implemented the KILL command to the client. Implemented the
3896 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3897 Affected files lib/silcclient/command[_reply].c and
3898 lib/silcclient/client_notify.c. Implemented the KILL notify
3899 printing in the user inteface.
3901 * Fixed a lot silc_parse_nick memory leaks from the client
3902 library in the file lib/silcclient/command.c.
3904 * Changed the silc_server_send_notify_on_channels's `sender'
3905 argument from SilcSocketConnection to SilcClientEntry to
3906 check the sender as entry and not as connection object and not
3907 to send to the client provided as argument. The affected file
3908 is silcd/packet_send.[ch].
3910 * The notify packets that are destined directly to the client used
3911 to not to be processed by the server. Now changed that and the
3912 server processes all notify packets. After relaying the packet
3913 to the client the notify packet is processed in the server.
3915 * The silc_server_free_client_data now checks whether there is
3916 pending outgoing traffic for the client and purges the data to
3917 the network before removing the client entry.
3919 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3922 an client is killed from the SILC Network. Updated the protocol
3925 Added new function silc_server_send_notify_killed to the
3926 silcd/packet_send.[ch].
3928 * Added function silc_server_packet_relay_notify to relay notify
3929 packets that are destined directly to a client. In this case
3930 the server does not process the notify packets but merely relays
3931 it to the client. Affected file silcd/packet_send.[ch].
3933 Added also silc_server_packet_process_relay_notify to check
3934 whereto relay the notify. Affected file is
3935 silcd/packet_receive.[ch].
3937 * Implemented the KILL command to the server.
3941 * Added the backup schema desgined last fall to the protocol
3942 specs for everyone to see. The specification is in the
3943 *-spec-xx.txt draft and the packet type definitions for the
3944 backup routers is in *-pp-xx.txt draft. Thusly, added also
3945 new packet type SILC_PACKET_CELL_ROUTERS.
3947 * A big security problem in the implementation discovered. The
3948 signoff of an client did not cause new channel key generation
3949 which it of course should've done. The channel keys must be
3950 always re-generated when client leaves (or signoffs) the channel.
3951 The silc_server_remove_from_channels funtion now handles
3952 the channel key re-generation.
3954 * Added `sender' argument to the silc_server_send_notify_on_channels
3955 to not to send the client provided as argument. Affected file
3956 silcd/packet_send.[ch].
3958 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Implemented OPER and SILCOPER commands into the server and
3963 * Added silc_auth_verify and silc_auth_verify_data to verify
3964 the authentication directly from the authentication payload.
3965 It supports verifying both passphrase and public key based
3966 authentication. Affected file lib/silccore/silcauth.[ch].
3968 * Added `hash' field to the SilcIDListData structure. It is the
3969 hash negotiated in the SKE protocol. Affected file is
3972 * Slight redesigning of the SilcAuthPayload handling routines.
3973 Do not send SilcPKCS but SilcPublicKey as argument.
3975 * Implemented the public key authentication support to the
3976 serverconfig. The public key is loaded from the provided path
3977 and saved as authentication data to void * pointer. Thus,
3978 changed the unsigned char *auth_data to void *auth_data;
3980 * Fixed SHUTDOWN command to send the reply before the server
3981 is shutdown. :) Affected file silcd/command.c.
3983 * Fixed fatal bug in CONNECT command. The hostname was invalid
3984 memory and server crashed. Affected file silcd/command.c.
3986 * Fixed fatal bug in CLOSE command. The server_entry became
3987 invalid but was referenced later in the command. Affected file
3990 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Fixed fatal bug in failure packet handling. Server ignored
3993 the failure and thus crashed when it came.
3997 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4000 that the command may be executed only once in (about) 2 seconds.
4001 The old SILC_CF_LAG flag is same but allows command bursts up
4002 to five before limiting.
4004 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4005 server code. Various commands now includes the CF_LAG_STRICT
4006 flag to disallow any kind of miss-use of the command.
4008 * Fixed the silc_buffer_unformat to not to allocate any data
4009 if the length of the data is zero. It used to allocate the
4010 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4012 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Changed the format of AdminConnection configuration section
4015 in the server. Added username of the admin to the format.
4016 Affected files silcd/serverconfig.[ch].
4018 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4019 to return admin configuration data by host, username and/or
4022 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Implemented WHOWAS command to the server. Added the functions:
4026 silc_server_command_whowas_parse,
4027 silc_server_command_whowas_send_reply,
4028 silc_server_command_whowas_from_client and
4029 silc_server_command_whowas_from_server
4031 * Added <Client ID> argument to the WHOWAS command reply. Updated
4032 the protocol specs accordingly.
4034 * Implemented WHOWAS command and command_reply to the client
4037 Implemented the WHOWAS printing on the user interface.
4039 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Added new argument to the WHOWAS command reply, the real name.
4042 It is an optional argument. Updated the protocol specs.
4044 * Added SilcIDCacheDestructor callback that is registered when
4045 the SilcIDCache is allocated. The callback is called when
4046 an cache entry in the ID Cache expires, or is purged from the
4047 cache. Added into lib/silccore/idcache.[ch].
4049 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4050 to destruct the client entries when the cache entry expires.
4051 Other ID Cache's in server and in the client library ignores
4054 * If the ID Cache entry's `expire' field is zero then the entry
4055 never expires. Added boolean `expire' argument to the
4056 silc_idcache_add function in the lib/silccore/idcache.[ch].
4057 If it is TRUE the default expiry value is used.
4059 * Added silc_server_free_client_data_timeout that is registered
4060 when client disconnects. By default for 5 minutes we preserve
4061 the client entry for history - for WHOWAS command.
4063 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Added support to the server to enforce that commands are not
4066 executed more than once in 2 seconds. If server receives
4067 commands from client more frequently, timeout is registered
4068 to process the commands. Affected file silcd/command.c.
4069 Added new function silc_server_command_process_timeout.
4071 * Changed NICK_NOTIFY handling in client library to check that
4072 if the client's nickname was changed, so there is no need to
4073 resolve anything from the server.
4075 * Removed error printing from the WHOIS and IDENTIFY commands.
4076 If error occurs then it is ignored silently in the client library.
4077 The application, however, may map the received error to
4078 human readable error string. The application currently maps
4079 the NO_SUCH_NICKNAME error to string.
4081 * Made the command status message public to the application. Moved
4082 them from lib/silcclient/command_reply.c to
4083 lib/silcclient/command_reply.h. The application can map the
4084 received command status to the string with the
4085 silc_client_command_status_message function.
4087 * Added check to the server to check that client's ID is same
4088 as the Source ID in the packet the client sent. They must
4091 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Added dist-bzip hook to the Makefile.am to make bzip2
4094 compressed distributions.
4096 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Server now enforces the maximum length for the nickname and
4099 the channel as protocol specification dictates. 128 bytes for
4100 nickname and 256 bytes for channel name.
4102 * Moved the WHOIS printing to the application. The client libary
4103 does not print out the WHOIS information anymore, the application
4104 must do it. Renamed silc_client_command_reply_whois_print to
4105 the silc_client_command_reply_whois_save.
4107 The client's idle time is also sent to the application now, and
4108 the idle is shown on screen.
4110 * Added silc_client_command_reply_identify_save to save the
4111 received IDENTIFY entries.
4113 * Do not check for channel private keys in message sending and
4114 reception if the channel does not have the PRIVKEY mode set.
4115 Affected file lib/silclient/client_channel.c.
4117 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4120 just surfaced after chaning the JOIN procedure.
4122 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Added silc_client_get_clients_by_list to get client entries
4125 from Client ID list, that is returned for example by JOIN
4126 and USERS command replies. The application should use this
4127 function for example when JOIN command reply is received to
4128 resolve the clients already on the channel (library does not
4129 do that anymore as USERS command reply is not used in the JOIN
4130 procedure anymore). Affected files lib/silcclient/silcapi.h and
4131 lib/silcclient/idlist.c.
4133 * JOIN command reply and USERS command reply returns now SilcBuffer
4134 pointers instead of unsigned char pointers when returning
4135 the client list and mode list.
4137 * Added <Client ID> argument to the JOIN command reply, mainly
4138 for the server to identify for which client the command was
4139 originally sent. Updated protocol specs accordingly.
4141 * Added SilcDlist private_key pointer to the SilcChannelEntry
4142 in the client to support the channel private keys. Affected
4143 file is lib/silcclient/idlist.h.
4145 * Added SilcChannelPrivateKey argument to the function
4146 silc_client_send_channel_message so that application can choose
4147 to use specific private ke if it wants to. If it is not provided,
4148 the normal channel key is used, unless private keys are set.
4149 In this case the first (key that was added first) is used
4150 as the encryption key.
4152 * Implemented the support for channel private key handling.
4153 Implemented the following functions:
4155 silc_client_add_channel_private_key,
4156 silc_client_del_channel_private_keys,
4157 silc_client_del_channel_private_key,
4158 silc_client_list_channel_private_keys and
4159 silc_client_free_channel_private_keys
4161 Affected file lib/silcclient/client_channel.c.
4163 * Added the support for the private keys in the channel message
4164 sending and encryption and in the message reception and
4165 decryption. Affected funtions are
4166 silc_client_send_channel_message and silc_client_channel_message.
4168 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Added SKE's key verify callback to the client library's
4171 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4173 * Removed the statement that server (or router) must send USERS
4174 command reply when joining to the channel so that the client
4175 knows who are on the channel. Instead, the client list and
4176 client's mode list is now sent in the JOIN command reply to the
4177 client who joined channel. This is better solution.
4179 * Added function silc_server_get_users_on_channel and function
4180 silc_server_save_users_on_channel to the silcd/server.[ch].
4182 * Removed function silc_server_command_send_users from the
4185 * Do not show topic on the client library anymore. The topic is
4186 sent in the command reply notify to the application and the
4187 application must show the topic now.
4189 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Added client searching by nickname hash into the IDENTIFY and
4192 WHOIS commands in the server as they were clearly missing from
4193 them. Affected file is silcd/command.c.
4195 * Fixed a bug in private message receiving in the client library.
4196 The remote ID was freed and it wasn't supposed, now it is
4199 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Minor fix to the channel payload; allocate the data area, as it
4202 needs to be of specific length.
4204 * If the key agreement port is zero then the operating
4205 system will define the bound port. Affected files are
4206 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4208 * Added new function silc_channel_payload_decrypt into the file
4209 lib/silccore/silcchannel.[ch].
4211 * Moved the channel message etc, check from silc_packet_decrypt
4212 to applications. The library calls now a generic
4213 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4214 when the packet is either normal or special. This was done to
4215 allow more wide range of checking that was not allowed when
4216 the code was in library. Now applications can do virtually any
4217 checks to the packet and return to the library the decision how
4218 the packet should be processed. Affected files are
4219 lib/silccore/silcpacket.[ch].
4221 Added silc_server_packet_decrypt_check to the server and
4222 silc_client_packet_decrypt_check to the client library.
4224 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4225 to send with specified source and destination information.
4227 * Channel message delivery between routers was broken after the
4228 channel key distribution was fixed earlier. The channel key
4229 was used be to distributed to other routers as well which is not
4230 allowed by the protocol. Now this is fixed and channel keys
4231 really are cell specific and the channel message delivery between
4232 routers comply with the protocol specification.
4234 * Fixed various commands in server to check also the global list
4235 for the channel entry and not just the local list. The affected
4236 file silcd/command.c.
4238 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Added assert()s to buffer formatting and unformatting routines
4241 to assert (if --enable-debug) when error occurs. Affected
4242 file: lib/silcutil/silcbuffmt.c.
4244 * Changed to auto-reconnect to check whether the remote host is
4245 router and register the re-connect timeout if it is. It used
4246 to check that whether we are normal server, but router must do
4247 auto-reconnect with another router as well. Affected file
4250 * Removed the [<key len>] option from CMODE command as the cipher
4251 name decides the key length, nowadays. See the defined ciphers
4252 from the protocol specification.
4254 * Added [<hmac>] option to the CMODE command to define the HMAC
4255 for the channel. Added SILC_CMODE_HMAC channel mode.
4257 * Added [<hmac>] option for the JOIN command so that user can
4258 select which HMAC is used to compute the MACs of the channel
4261 * Added Hmac field to the Channel Message Payload. The integrity
4262 of plaintext channel messages are now protected by computing
4263 MAC of the message and attaching the MAC to the payload. The
4264 MAC is encrypted. Now, it is clear that this causes some
4265 overhead to the size of the packet but rationale for this is that
4266 now the receiver can verify whether the channel message decrypted
4267 correctly and also when private keys are set for the channel the
4268 receiver can decrypt the packet with several keys and check from
4269 the MAC which key decrypted the message correctly.
4271 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4272 lib/silccrypt/silccipher.[ch].
4274 * Added silc_hash_len to return the digest length into the
4275 lib/silcrypt/silchash.[ch].
4277 * Rewrote parts of Silc Channel Payload interface in the
4278 lib/silccore/silcchannel.[ch]. The encode function now also
4279 encrypts the packet and parse function decrypts it.
4281 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Fixed a minor formatting bug in the SKE's key material processing.
4284 It actually might have processed the keys wrong way resulting
4287 * Redefined the mandatory HMAC algorithms and added new algorithms.
4288 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4289 and hmac-md5 truncated to 96 bits. The mandatory is now
4290 hmac-sha1-96. Rest are optional (including the one that used
4291 to be mandatory). Rationale for this is that the truncated HMAC
4292 length is sufficient from security point of view and can actually
4293 make the attack against the HMAC harder. Also, the truncated
4294 HMAC causes less overhead to the packets. See the RFC2104 for
4297 * Added new [hmac] configuration section. The SKE used to use
4298 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4299 is of course wrong. The official names that must be proposed in
4300 the SKE are the ones defined in the protocol specification
4301 (hmac-sha1-96 for example). The user can configure any hmac
4302 using any hash function configured in the [hash] section. At
4303 least, the mandatory must be configured.
4305 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4307 * Added HMAC list to the SKE proposal list. It has now both
4308 hash algorithm list and HMAC list. This makes the protocol
4309 incompatible with previous versions. The SKE now seems to work
4310 the way it is supposed to work, for the first time actually.
4312 * Defined plain Hash algorithms to the protocol specification.
4315 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Implemented support for key agreement packets into the server.
4318 Added functions silc_server_key_agreement and
4319 silc_server_send_key_agreement. Other than these functions,
4320 server has nothing to do with this packet.
4322 * Added support for private message key packets into the server.
4323 Added functions silc_server_private_message_key and
4324 silc_server_send_private_message_key.
4328 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4329 called in the protocol's final callback instead in the END
4330 protocol state. This makes a little more sense and in the same
4331 time in client we can use the same protocol routines for normal
4332 key exchange and to key agreement packet handling as well.
4334 * Added to both client's and server's KE protocol context the
4335 SilcSKEKeyMaterial pointer to save the key material. We will
4336 bring the key material to the protocol's final callback by doing
4337 this. The final callback must free the key material.
4339 * Added SKE's packet_send callback into client's KE protocol
4340 context so that the caller can choose what packet sending function
4341 is used. This way we can use different packet sending when
4342 doing normal SKE when doing key agreement packet handling (in
4343 the key agreement packet handling we do not want to encrypt
4346 * Implemented the responder side of the key agreement routines
4347 in the client. The client can now bind to specified port and
4348 accept incoming key negotiation. The key material is passed
4349 to the application after the protocol is over.
4351 * Implemented the processing of incoming Key Agreement packet
4352 in the client. Added function silc_client_key_agreement to
4355 * Implemented the intiator side of the key agreement routines
4356 in the client. The client can now initiate key agreement with
4357 another remote client. The key material is passed to the
4358 application after the protocol is over.
4360 * Created client_keyagr.c to include all the key agreement
4363 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4364 SILC_TASK_CALLBACK except that it is not static.
4366 * Created client_notify.c and moved the Notify packet handling
4367 from the client.[ch] into that file.
4369 * Created client_prvmsg.c and moved all private message and
4370 private message key routines from the client.[ch] into that file.
4372 * Create client_channel.c and moved all channel message and
4373 channel private key routines from the client.[ch] into that file.
4375 * Changed silc_client_get_client_by_id_resolve to resolve with
4376 WHOIS command instead of IDENTIFY command, in the file
4377 lib/silclient/idlist.c.
4379 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Implemented the SKE's responder side to the Client library.
4383 * When FAILURE is received to the protocol do not trust it
4384 blindly. Register a timeout to wait whether the remote closes
4385 the connection as it should do it, only after that process the
4386 actual failure. This was changed to both client and server.
4388 * Added client_internal.h to include some of the structures
4389 there instead of client.h in lib/silcclient/.
4391 * Added function silc_task_unregister_by_callback to unregister
4392 timeouts by the callback function.
4394 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Some "Incomplete WHOIS info" errors has been appearing on the
4397 log files. Took away the entry->userinfo check from WHOIS
4398 reply sending. The entry->userinfo is now " " if client did not
4399 provide one. I thought this was fixed earlier but something
4400 is wrong still. Let's see if the error still appears.
4402 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Fixed a minor bug in the login when the channel key is
4405 re-generated in the server. It used to generate the key in
4406 wrong order and thus caused problems in the channel traffic.
4408 * Fixed a minor bug in channel key distsribution after
4409 KICK command. The key was not sent to the router even though
4412 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Added silc_ske_process_key_material_data as generic routine
4415 to process any key material as the SILC protocol dictates. The
4416 function is used by the actual SKE library but can be used by
4417 applications as well. This relates to the private message keys
4418 and the channel private keys since they must be processed the
4419 same way the normal SILC session keys. The protocol dictates
4420 this. Affected files: lib/silcske/silcske.[ch].
4422 Added also silc_ske_free_key_material to free the
4423 SilcSKEKeyMaterial structure.
4425 * Defined silc_cipher_set_key function to set the key for
4426 cipher without using the object's method function. The affected
4427 files: lib/silccrypt/silccipher.[ch].
4429 * Implemented silc silc_client_add_private_message_key,
4430 silc_client_add_private_message_key_ske,
4431 silc_client_del_private_message_key,
4432 silc_client_list_private_message_keys and
4433 silc_client_free_private_message_keys functions in the
4436 Added functions silc_client_send_private_message_key to send
4437 the Private Message Key payload and silc_client_private_message_key
4438 to handle incoming Private Message Key payload.
4440 * Added Cipher field to the Private Message Key payload to set
4441 the cipher to be used. If ignored, the default cipher defined
4442 in the SILC protocol (aes-256-cbc) is used.
4444 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Removed lib/silcclient/ops.h file.
4448 Redefined parts of the SILC Client Library API. Created new
4449 file silcapi.h that deprecates the ops.h file and defines the
4450 published Client Library API. Defined also private message key
4451 API and channel private key API into the file.
4453 This is the file that the application must include from the
4454 SILC Client Library. Other files need not be included by
4455 the application anymore.
4457 * Added new key_agreement client operation callback and also
4458 defined the Key Agreement library API for the application.
4460 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4463 is used by clients to request key negotiation between another
4464 client in the SILC network. If the negotiation is started it
4465 is performed using the SKE protocol. The result of the
4466 negotiation, the secret key material, can be used for example
4467 as private message key.
4469 Implemented the Key Agreement payload into the files
4470 lib/silccore/silauth.[ch].
4472 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Redefined ciphers for the SILC protocol. Added some new ciphers
4475 and defined the key lengths for the algorithms. Changed the
4476 code accordingly. The default key length is now 256 bits.
4478 * Fixed SKE key distribution function silc_ske_process_key_material
4479 when the key length is more than 128 bits. The default key
4480 length in SILC is now 256 bits.
4482 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4483 to indicate unsupported algorithm.
4485 * Renamed rijndael.c to aes.c and all functions as well.
4487 * Fixed a long standing channel key setting bug in client library.
4488 Weird that it has never surfaced before.
4490 * Fixed bug in channel deletion. If the entire channel is removed
4491 then it must also delete the references of the channel entry
4492 from the client's channel list as the client's channel entry and
4493 the channel's client entry share same memory.
4495 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Implemented CONNECT and SHUTDOWN commands in the client.
4499 * Implemented CLOSE command to the client.
4501 * Added the function silc_idlist_find_server_by_name into the
4502 files silcd/idlist.[ch].
4504 Added the function silc_idlist_find_server_by_conn into the
4505 files silcd/idlist.[ch].
4507 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * DIE command was renamed to SHUTDOWN. Updated the both code
4512 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4513 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4515 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4518 * Added function silc_server_create_connection function to create
4519 connection to remote router. My server implementation actually
4520 does not allow router to connect to normal server (it expects
4521 that normal server always initiates the connection to the router)
4522 so the CONNECT command is only good for connecting to another
4525 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4528 or some other client was kicked from the channel.
4530 Implemented the handling of the notify type to both client
4533 Implemented silc_server_send_notify_kicked to send the KICKED
4534 notify. It is used to send it to the server's primary router.
4536 * Implemented the KICK command into server and client.
4538 * Added `query' argument to the silc_idlist_get_client function
4539 to indicate whether to query the client from server or not if
4542 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4543 to indicate that the client is not channel founder.
4547 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Removed the rng context from SilcPacketContext structure and
4550 changed that the packet routine uses the Global RNG API.
4552 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added support for quit message that client can "leave" on the
4555 channel when it quits the SILC. It is ditributed inside the
4556 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4558 Added silc_server_free_client_data that will take the
4559 signoff message as argument.
4561 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4563 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Updated parts of the protocol specification to keep it up
4568 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4571 payloads in one packet.
4573 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4574 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4575 use now the new List flag.
4577 * Also deprecated the following packet types: REPLACE_ID,
4578 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4580 * Added list support for Notify packet in server.
4582 * Added silc_server_send_notify_channel_change to send the
4583 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4584 the silc_server_send_replace_id.
4586 * Added silc_server_send_notify_nick_change to send the
4587 NICK_CHANGE notify type. Deprecates the function
4588 silc_server_send_replace_id.
4590 * Added silc_server_send_notify_join to send the JOIN notify type.
4591 Deprecates the function silc_server_send_new_channel_user.
4593 * Added silc_server_send_notify_leave to send LEAVE notify type.
4594 Deprecates the function silc_server_send_remove_channel_user.
4596 * Added silc_server_send_notify_cmode and
4597 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4598 types. Deprecates the silc_server_send_set_mode function.
4600 * Added SERVER_SIGNOFF notify type to indicate that server has
4601 quit. This means that all clients on the channel from that
4602 server will drop. This can be also used when netsplit happens.
4604 Deprecated REMOVE_ID packet type since it is not needed anymore
4607 Added silc_server_send_notify_server_signoff to send the
4608 SERVER_SIGNOFF notify type. Deprecates the function
4609 silc_server_send_remove_id.
4611 Added also silc_server_send_notify_signoff to send the
4612 SIGNOFF notify type.
4614 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4615 SILC protocol from this day on. Changed the protocol
4616 specification as well.
4618 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4619 notify type. It is used between routers to notify about
4620 topic changes on a channel.
4622 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4625 * Partly updated the protocol specification to comply with the
4626 changes now made. It is still though a bit outdated.
4628 * The JOIN notify type now takes one extra argument <Channel ID>.
4629 The packet used to be destined to the channel but now the
4630 JOIN type may be sent as list thus it is impossible to
4631 destine it to any specific channel. By adding this argument
4632 it is again possible.
4634 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Added CREDITS file. The CHANGES and CREDITS file will appear
4637 in the distribution as well.
4639 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4642 types in the server's silcd/packet_receive.c.
4644 * Implemented CMODE and CUMODE to work in router environment.
4646 * Fixed minor encoding and decoding buglet from the
4647 lib/silccore/silcmode.c.
4649 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4652 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4654 * Changed all SilcConfigServer* and silc_config_server* to
4655 SilcServerConfig* and silc_server_config*, respectively.
4658 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Associated the ID (client or server ID) to the Authentication
4661 Payload to avoid any possibility of forging. Updated the
4662 protocol specification and the code accordingly.
4664 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * The RSA key length is now save to the RsaKey context in the
4667 key generation process in lib/silccrypt/rsa.c. The key length
4668 is now used to figure out the maximum size of the block allowed
4669 to be encrypted/signed.
4671 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4672 is equivalent to the silc_mp_mp2bin but does not allocate any
4675 * Changed silc_mp_mp2bin API to take length argument. If it is
4676 non-zero then the buffer is allocated that large. If zero, then
4677 the size is approximated using silc_mp_sizeinbase, which however
4680 * Created Global RNG API which is global RNG that application can
4681 initialize. After initializing, any routine anywhere in the
4682 code (including library) can use RNG without allocating a new
4683 RNG object. This was done to allow this sort of use of the
4684 RNG in code that has no chance to allocate RNG object. All
4685 applications currently allocate this and many routines in the
4686 library use this. Affected file lib/silccrypt/silcrng.[ch].
4688 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4689 it to use the Global RNG API.
4691 * Defined Authentication Payload into protocol specification that
4692 is used during SILC session to authenticate entities. It is
4693 used for example by client to authenticate itself to the server
4694 to obtain server operator privileges.
4696 Implemented this payload into the lib/silccore/silcauth.[ch].
4697 Implemented also routines for public key based authentication
4698 as the new protocol specification dictates.
4700 Moved definitions of different authentication methods from
4701 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4703 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4704 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4705 silc_pkcs_verify_with_hash functions into the file
4706 lib/silccrypt/silcpkcs.[ch].
4708 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * The client entry's userinfo pointer must be always valid.
4711 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4712 will fail since it requires the userinfo. Now, the userinfo
4713 is allocated as "" if actual userinfo does not exist. Actually,
4714 it must exist and it is totally Ok to drop client connections
4715 that does not announce the userinfo. However, we will make
4716 this workaround for now.
4718 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4719 to return the remote port by socket.
4721 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4724 SILC_SERVER_PENDING_EXEC and added an new macro
4725 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4726 data or when error occurs while processing the pending command.
4728 Added new argument `destructor' into silc_server_command_pending
4729 and to the SilcServerCommandPending object. This destructor is
4730 now called after calling the pending callback or if error occurs
4731 immediately. If error occurs the actual pending callback won't
4732 be called at all - only the destructor. The destructor may be
4733 NULL if destructor is not needed.
4735 All this applies for client library code as well. Similar
4736 changes were made there as well for the pending commands.
4738 In the client, the application must now allocate the
4739 SilcClientCommandContext with the silc_client_command_alloc
4742 * Added reference counter to the SilcServerCommandContext. Added
4743 function silc_server_command_alloc and silc_server_command_dup
4746 Same type of functions added to the client library for the same
4749 * Removed the cmd_ident from IDListData away since it is now
4750 global for all connections. It is the command identifier used
4751 in command sending and with pending commands. The affected file
4754 * Added reference counter to the SilcSocketConnection objecet to
4755 indicate the usage count of the object. The object won't be
4756 freed untill the reference counter hits zero. Currently only
4757 server uses this, and client ignores it. The client must be
4758 set to use this too later. The affected files are
4759 lib/silccore/silcsockconn.[ch]. Added also the function
4760 silc_socket_dup to increase the reference counter.
4762 This was mainly added because it is possible that the socket
4763 is removed underneath of pending command or other async
4764 operation. Now it won't be free'd and proper DISCONNECTING
4765 flags, etc. can be set to avoid sending data to connection that
4766 is not valid anymore.
4768 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4769 the connection. After that it sets SILC_SET_DISCONNECTED.
4770 It is, however, possible that the socket data is not still freed.
4771 The silc_server_packet_process now checks that data is not
4772 read or written to connection that is DISCONNECTED. The socket
4773 get's freed when the reference counter hits zero.
4775 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Changed the client operation API: channel_message operation's
4778 `sender' is now the client entry of the sender, not the nickname
4779 and the `channel' is the channel entry, not the channel name.
4781 In the private_message operation the `sender' is now also the
4782 client entry of the sender not the nickname.
4784 Affected file is lib/silcclient/ops.h and all applications
4785 using the client operations.
4787 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Moved the calling of ops->connect() from connect_to_server_final
4790 into receive_new_id functin since that is the point when the
4791 client is actually allowed to send traffic to network. The
4792 affected file is lib/silcclient/client.c.
4794 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4797 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4798 (if needs broadcasting) instead of broadcasting the packets one
4799 by one which would make a burst in the network traffic.
4801 * Added `broadcast' argument to the functions in silcd/server.[ch]
4802 silc_server_create_new_channel[_with_id] to indicate whether
4803 to send New Channel packet to primary router.
4805 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added new function into the silcd/server.[ch] files:
4808 silc_server_create_new_channel_with_id to create new channel with
4809 already existing Channel ID.
4811 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4812 lib/silccore/silcpacket.h. This packet is used t send list of
4813 Set Mode payloads inside one packet. Server uses this to set
4814 the modes for the channels and clients on those channels, that it
4815 announced to the router when it connected to it. The protocol
4816 specification has been updated accordingly.
4818 * The silc_server_new_channel did not handle the packet coming
4819 from normal server as it normally does not send that. However,
4820 when it announces its channels it does send it. Implemented
4821 the support for that.
4823 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4824 into the file lib/silccore/id.h.
4826 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Fixed memory leaks in the functions silc_idlist_del_client,
4829 silc_idlist_del_channel and silc_idlist_del_server in the file
4830 silcd/idlist.c. All of those leaked like a sieve.
4832 * Fixed some small memory leaks in the client's function
4833 silc_client_notify_by_server.
4835 * Added functions into silcd/server.c: silc_server_announce_clients,
4836 silc_server_announce_channels and silc_server_announce_server.
4837 These functions are used by normal and router server to announce
4838 to its primary router about clients, channels and servers (when
4839 router) that we own. This is done after we've connected to the
4842 These functions effectively implements the following packet types:
4843 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4844 and SILC_PACKET_NEW_ID_LIST.
4846 * Added new functions into the silcd/packet_receive.[ch]:
4847 silc_server_new_id_list, silc_server_new_channel_list and
4848 silc_server_new_channel_user_list to handle the incoming
4849 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4851 * Added support of changing Channel ID in the function
4852 silc_server_replace_id. If the server that announces a channel
4853 to the router already exists in the router (with same name but
4854 with different Channel ID), router is responsible to send
4855 Replace ID packet to the server and force the server to change
4856 the Channel ID to the one router has.
4858 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4859 client that the Channel ID has been changed by the router. The
4860 normal server sends this to the client. Client must start using
4861 the new Channel ID as the channel's ID.
4863 Implemented handling of this new type into lib/silcclient/client.c
4864 into the function silc_client_notify_by_server.
4866 * Added new function silc_idlist_replace_channel_id into the files
4867 silcd/idlist.[ch] to replace the Channel ID.
4869 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Call silc_server_command_identify_check always when processing
4872 the IDENTIFY command in silcd/command.c
4874 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4877 send keepalive packets. The packet can be sent by clients,
4878 servers and routers.
4880 Added function silc_socket_set_heartbeat into the file
4881 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4882 If not set, the heartbeat is not performed. The actual
4883 heartbeat is implemented in the low level socket connection
4884 library. However, application is responsible of actually
4887 Added silc_server_send_heartbeat to send the actual heartbeat
4888 packet into silcd/packet_send.[ch]. Server now performs
4889 keepalive with all connections.
4891 * Added silc_task_get_first function into lib/silcutil/silctask.c
4892 to return the timeout task with shortest timeout. There was a bug
4893 in task unregistration that caused problems. TODO has been
4894 updated to include that task system must be rewritten.
4896 * The client library will now resolve the client information when
4897 receiving JOIN notify from server for client that we know but
4898 have incomplete information.
4900 * Rewrote parts of silc_server_remove_from_channels and
4901 silc_server_remove_from_one_channel as they did not remove the
4902 channel in some circumstances even though they should've.
4904 * Encryption problem encountered in server:
4906 The LEAVE command used to send the Channel Key packet to the
4907 router immediately after generating it. However, the code
4908 had earlier sent Remove Channel user packet but not immediately,
4909 ie. it was put to queue. The order of packets in the router
4910 was that Channel Key packet was first and Remove Channel User
4911 packet was second, even though they were encrypted in the
4912 reverse order. For this reason, MAC check failed. Now, this
4913 is fixed by not sending the Channel Key packet immediately but
4914 putting it to queue. However, this is more fundamental problem:
4915 packets that are in queue should actually not be encrypted
4916 because packets that are sent immediately gets encrypted
4917 actually with wrong IV (and thus MAC check fails). So, packets
4918 that are in queue should be encrypted when they are sent to
4919 the wire and not when they put to the queue.
4921 However, the problem is that the current system has not been
4922 designed to work that way. Instead, the packet is encrypted
4923 as soon as possible and left to the queue. The queue is then
4924 just purged into wire. There won't be any fixes for this
4925 any time soon. So, the current semantic for packet sending
4928 o If you send packet to remote host and do not force the send
4929 (the packet will be in queue) then all subsequent packets to the
4930 same remote host must also be put to the queue. Only after the
4931 queue has been purged is it safe again to force the packet
4934 o If you send all packets immediately then it safe to send
4935 any of subsequent packets through the queue, however, after
4936 the first packet is put to queue then any subsequent packets
4937 must also be put to the queue.
4939 Follow these rules and everything works fine.
4941 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Added new function silc_server_remove_clients_by_server to
4944 remove all client entries from ID list when the server connection
4945 is lost. In this case it is also important to invalidate all
4946 client entires as they hold the invalid server entry. This
4947 fixes fatal bug when server has lost connection and will reconnect
4950 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Made some sanity checks to silc_server_daemonise like to check
4953 whether the requested user and group actually exists.
4955 * Added sanity check to SKE's silc_ske_responder_finish to check
4956 that the public and private key actually is valid.
4958 * Invalidate the client's nickname when receiving Replace ID
4959 packet and the Client ID is being replaced. This means that the
4960 server will query the nickname if someone needs it (client)
4963 * Sort the ID Cache in client library when the ID Cache data
4964 has changed (needs sorting).
4966 * Do not allow for SILC client to create several connections to
4967 several servers. The client does not support windows right now
4968 and generating multiple connections causes weird behaviour.
4970 Irssi-silc client does support windows and can handle several
4971 connections without problems, see: www.irssi.org and SILC plugin.
4973 * Fixed some places where client was added to the IDList. The
4974 rule of thumb is following (in order to get everything right):
4975 If the client is directly connected local client then the
4976 `connection' argument must be set and `router' argument must be
4977 NULL to silc_idlist_add_client function. If the client is not
4978 directly connected client then the `router' argument must
4979 bet set and the `connection' argument must be NULL to the
4980 silc_idlist_add_client function.
4982 * The funtion silc_server_packet_send_local_channel actually did
4983 not check whether the client was locally connected or not. It
4984 does that now. Fixed a bug related to LEAVE command.
4986 * Fixed Remove Channel User payload parsing bug in server's
4987 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4989 * The server's silc_server_save_channel_key now checks also the
4990 global ID list for the channel as it might not be in the local
4991 list. Fixed a bug related to LEAVE command.
4993 * Is this the end of the [<unknown>] buglet that has been lurking
4994 around for a long time? A little for loop fix in server's
4995 silc_server_command_whois_parse that is used by both IDENTIFY
4996 and WHOIS command. At least, this was a clear bug and a cause
4997 of one type of [<unknown>] buglet.
4999 * WHOIS and IDENTIFY commands call the function
5000 silc_server_command_[whois/identify]_check function even if
5001 we are not router server.
5003 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Added --with-gmp configuration option. If set the GMP
5006 is always compiled in the SILC source tree. If not set then
5007 it is checked whether the system has the GMP3 installed. If
5008 it has then the GMP won't be compiled (the system's headers
5009 and library is used), if it doesn't have it then the GMP is
5010 compiled in the SILC source tree.
5012 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Changed RSA private exponent generation to what PKCS #1
5015 suggests. We try to find the smallest possible d by doing
5016 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5017 not security fix but optimization.
5019 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Added new config entry [Identity] to fork the server and run
5022 it as specific user and group. A patch from Bostik.
5024 * Imported Dotconf configuration library into lib/dotconf.
5025 This will be used to create the SILC configuration files later.
5026 It will appear in the distsribution after this commit.
5028 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * A big code auditing weekend happening. Auditing code for
5031 obvious mistakes, bugs and errors. Also, removing any code
5034 Removed files for being obsolete:
5036 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5037 inline in the file lib/silcutil/silcbuffer.h)
5039 o lib/silcutil/silcbufutil.c (the header has inline versions)
5041 Changed code to fix possible error conditions:
5043 o The buffer formatting routines now check that the destination
5044 buffer really has enough space to add the data. This applies for
5045 both buffer formatting and unformatting
5046 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5047 unformatting was changed to accomodate following rules:
5048 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5049 sent to the function while XXX_*STRING will not allocate or copy
5050 the data into the buffer. Instead it sets the pointer from the
5051 buffer into the pointer sent as argument (XXX_*STRING used to
5052 require that the pointer must be allocated already). This change
5053 makes this whole thing a bit more consistent and more optimized
5054 (note that the data returned in the unformatting with XXX_*STRING
5055 must not be freed now). The routines return now -1 on error.
5057 o Tried to find all code that use buffer_format and buffer_unformat
5058 and added return value checking to prevent formatting and
5059 especially unformatting errors and possible subsequent fatal
5062 o Changed ske->x and ske->KEY to mallocated pointers in
5063 lib/silcske/silcske.h. Fixed possible data and memory leak.
5065 o Added return value checking to all *_parse* functions. Fixed
5066 many memory leaks as well.
5068 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5069 so that buffer overflows would not happen. All code now also
5070 checks the return value as it can fail.
5072 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Added reconnection support to server if the normal server looses
5075 its connection to the router (for example if router is rebooted).
5076 The server performs normal reconnection strategy implemented
5077 to the server. Affected file silcd/server.c.
5079 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Added new packet type SILC_PACKET_SET_MODE that is used to
5082 distribute the information about changed modes (for clients,
5083 channels and clients channel modes) to all routers in the
5084 network. Updated the protocol specification accordingly.
5086 Added functions into silcd/packet_send.c and
5087 silcd/packet_receive.c: silc_server_send_set_mode,
5088 silc_server_set_mode.
5090 Added new files silcmode.[ch] into lib/silccore that implements
5091 the encoding and decoding of Set Mode Payload. Added new type
5092 SilcSetModePayload. Moved the definitions of different modes
5093 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5095 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Oops, a little mistake in server's connection authentication
5098 protocol. The protocol is not ended with FAILURE but with
5099 SUCCESS if the authentication is Ok. :) Affected file is
5102 * Implemented NICK_CHANGE notify handling in server in the file
5103 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5104 the local clients on the channel. After the changing nickname
5105 in router environment snhould work and the [<unknown>] nickname
5106 should appear no more.
5108 The silc_server_replace_id function that receives the Replace ID
5109 payload now sends the NICK_CHANGE notify type also in the file
5110 silcd/packet_receive.c
5112 * Changed WHOIS and IDENTIFY command to support the maximum amount
5113 of arguments defined in protocol specs (3328 arguments). This
5114 fixed a bug that caused problems when there were more than three
5117 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Added extra parameter, command identifier, to the
5120 silc_client_send_command so that explicit command identifier
5123 Changed that ID list routines uses specific command identifier
5124 when sending WHOIS/IDENTIFY requests to the server so that they
5125 can be identified when the reply comes back.
5127 Affected files lib/silcclient/command.[ch],
5128 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5130 * Added `sender' argument to silc_server_packet_send_to_channel
5131 to indicaet the sender who originally sent the packet to us
5132 that we are now re-sending. Ignored if NULL. Affected file
5133 silcd/packet_send.[ch].
5135 * Added some server statistics support in silcd/server_internal.h
5136 SilcServerStatistics structure and around the server code. Also
5137 send some nice statistics information when client is connecting
5140 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Fixed channel ID decoding in server's JOIN command reply in
5143 silcd/command_reply.c
5145 * Fixed braodcasting of replace ID payload to not to send it if
5146 we are standalone server in silcd/packet_receive.c.
5148 * Fixed all channel message sending routines to not to send
5149 packets to clients that has router set, since they are routed
5150 separately in the same function earlier. Affects file
5151 silcd/packet_send.c and all channel packet sending functions.
5153 * In USERS reply, res_argv[i] are not allocated, the table
5154 is allocated. Thus changed that free the table, not its
5157 * In server's whois_check and identify_check if the client is
5158 locally connected do not send any WHOIS commands - they are not
5161 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Fixed some minor bugs in client when sending WHOIS command. The
5164 arguments was in wrong order.
5166 * Removed statis function add_to_channel from server in
5167 silcd/command.c that was previously used with the joining but
5170 * Tested USERS command in router environment successfully with two
5171 routers, two servers and two clients.
5173 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Reorganized the USERS command and command reply in client library
5176 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5177 When the command is given by user we register a pending command
5178 callback that will reprocess the command after the reply has been
5179 received from the server. When reprocessing the packet we then
5180 display the information. Thus, the USERS information is displayed
5181 now in the command callback instead of in the command reply
5182 callback. The processing of the command is same as previously
5183 when server has sent the command reply in the JOINing process.
5185 * Added to USERS command in silcd/command_reply.c to join the client,
5186 we didn't use to know about, to the channel after we've created
5187 a client entry for it. Also, for clienet we did know already still
5188 check whether it is on the channel or not and add it if not.
5190 * Removed silc_server_command_join_notify as the function and its
5193 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Changed the client's pending command handling to the same as the
5196 server's pending command handling. It is also now possible to
5197 execute command reply functions from other command reply
5198 function as the function callbacks for commands and command
5199 replies are one and same. The pending commands are not static
5200 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5201 in client connection context. Thus, pending commands are server
5202 connection specific as it is convenient.
5204 Changed the function silc_client_command_pending and
5205 silc_client_command_pending_del and added new function
5206 silc_client_command_pending_check. Removed the
5207 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5210 * Added cmd_ident, current command identifier, to the client
5211 connection context in lib/silcclient/client.h to keep track on
5212 command identifiers used in command sending. Client's command reply
5213 function handling now supports the mandatory command identifiers.
5215 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5216 funtions in client to fully support pending command callbacks.
5218 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5219 as one of the arguments to the application in the command reply
5222 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5223 before first releasing SILC but came back. Now it is removed again
5224 and should come back nomore. The FORWARDED flag was used only
5225 by the JOINing procedure by forwarding the command packet to router.
5226 Now, the JOINing procedure has been changed to more generic (due
5227 to various router environment issues) and FORWARDED is not needed
5228 anymore for anything. The protocol specification is yet to be
5231 Now, removed silc_server_packet_forward from server and the flag
5232 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5234 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Renamed NAMES command to USERS command. The NAMES was named that
5237 due to historical reasons. Now it is renamed. Also, rewrote
5238 parts of the USERS command. The nickname list is not sent anymore
5239 by the server. Only Client ID and mode lists are sent in the USERS
5240 command. Changed this also to the protocol specification.
5242 The client now resolves the names and stuff after it receives
5243 the USERS list from the server when joining to the channel.
5245 * WHOIS and IDENTIFY commands has been changed to support multiple
5246 Client ID's per command. One can now search for multiple users
5247 in the network by sending only one WHOIS or IDENTIFY command.
5248 Changed the code and the protocol specifications.
5250 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5251 uses silc_server_command_whois_parse to parse the request. */
5253 * If normal server, do not parse the WHOIS and IDENTIFY requests
5254 before sending it to the router. Saves some time.
5256 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Fixed JOIN command on client library. Wrong number of arguments
5259 used to crash the client.
5261 * Added silc_server_channel_has_global function to check whether
5262 channel has global users or not.
5264 * Added silc_server_channel_has_local function to check whether channel
5265 has locally connected clients on the channel.
5267 * The silc_server_remove_from_one_channel now checks whether the
5268 channel has global users or not after given client was removed from
5269 the channel. It also checks whether the channel has local clients
5270 on the channel anymore. If it does not have then the channel entry
5271 is removed as it is not needed anymore.
5273 * The silc_server_notify now checks on JOIN notify whether the joining
5274 client is one of locally connected or global. If it is global then
5275 the channel has now global users on the channel and that is marked
5276 to the channel entry. Also, it now saves the global client to
5277 global list who is joining and JOINs it to the channel. This is
5278 for normal server, that is.
5280 Changed silc_server_send_notify_on_channel,
5281 silc_server_packet_relay_to_channel and
5282 silc_server_packet_send_to_channel check if we are normal server
5283 and client has router set (ie. global client) do not send the
5284 message to that client, as it is already routed to our router.
5286 * Implemented LEAVE notify type handling in silc_server_notify
5289 * Tested LEAVE command in router environment successfully. Tested
5290 with two routers, two servers and two clients.
5294 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5296 * Implemented SIGNOFF notify type handling in silc_server_notify
5299 * silc_server_remove_id now removes the client entry from all channels
5300 it has joined and thusly sends SIGNOFF notify type.
5302 * Rewrote the NAMES list generation in server by removing two excess
5303 loops. The lists are created now inside one loop.
5305 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * silc_server_remove_channel_user checks now also global list
5308 for channel and client.
5310 * silc_server_new_channel_user checks now both local and global
5311 list for channel and client. Fixed a bug in client id decoding.
5312 Used to decode wrong buffer.
5314 * silc_server_channel_message checks now both local and global
5315 list for channel entry.
5317 * Tested channel joining (hence JOIN) in router environment
5318 successfully. Tested with two routers, two servers and two
5321 * Tested channel message sending in router environment successfully.
5323 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Added silc_server_save_channel_key into server.[ch] to save the
5326 received channel key in Channel Key payload processing. It is
5327 also used in JOIN command reply handling.
5329 Equivalent function silc_client_save_channel_key added into
5330 client.[ch] into client library.
5332 * Changed JOIN command reply to send information whether the channel
5333 was created or not (is existing already) and the channel key
5334 payload. Changed protocol specs accordingly.
5336 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5337 the request was sent by ID and not by nickname. Crashed on
5340 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5342 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5343 now correctly save the received data.
5345 * silc_server_free_sock_user_data now notifies routers in the
5346 network about entities leaving the network.
5348 At the same time implemented functions silc_server_remove_id
5349 and silc_server_send_remove_id to receive and send REMOVE_ID
5350 packets. The packet is used to notify routers in the network
5351 about leaving entities. The ID removed will become invalid in
5354 * Added function silc_idlist_del_server into server. Removes and
5355 free's server entry from ID list.
5357 * silc_server_private_message function now checks, if we are router,
5358 that the destination ID really is valid ID, naturally.
5360 * In router when NEW_ID packet is received (for new client) the
5361 hash of the Client ID is saved in the ID Cache but the
5362 client->nickname is set to NULL, instead of putting the hash
5365 IDENTIFY command now also checks that client->nickname must be
5366 valid. If it is not if will request the data from the server who
5367 owns the client. Added new function
5368 silc_server_command_identify_check.
5370 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5371 to set the command to already allocated Command Payload.
5373 * Tested private message sending in router environment with two
5374 routers, two servers and two clients. Fixed minor bugs and now
5377 * Fixed segfault from client's NAMES command. Used to crash if
5380 * Forwarded packets must not be routed even if it is not destined
5381 to the receiver. Changed server code comply with this.
5383 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Added `require_reverse_mapping' boolean value to ServerParams
5386 structure. If TRUE (not default) the server will require that
5387 the connecting host has fully qualified domain name.
5389 If the reverse mapping is not required and hostname could not be
5390 found the IP address is used as hostname.
5392 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Implemented version string checking to both client and server.
5395 The check is incomplete currently due to the abnormal version
5396 strings used in development version of SILC.
5398 * Changed all command functions in server to use the new
5401 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Changed char *data to unsigned char *data in ID Cache system to
5404 support binary data as ID Cache data. Changed code to support
5405 binary data in lib/silccore/idcache.c.
5407 * Renamed silc_server_packet_relay_command_reply to
5408 silc_server_command_reply as it is normal packet receiving
5409 function. Rewrote the function to accept command replys for
5410 servers and not only for clients.
5412 * Mark remote router always as registered server if we are connecting
5413 to it. Otherwise, commands sent by the router to us are ignored.
5415 * All ID List find routines now returns the ID Cache Entry pointer
5416 as well if requested.
5418 * WHOIS command works now in router environment, tested with two
5419 routers, two servers and two clients.
5421 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5422 in router environment (as it is almost equivalent to WHOIS) but
5423 hasn't been tested thoroughly. Added new functions:
5425 silc_server_command_identify_parse
5426 silc_server_command_identify_send_reply
5427 silc_server_command_identify_from_client
5428 silc_server_command_identify_from_server
5430 * Disabled route cache adding because adding two different ID's with
5431 same IP replaces the old cache entry thus giving wrong route.
5432 The entry->router->connection is always the fastest route anyway
5433 so route cache may not be needed. Of course, new routes maybe
5434 established after receiving the ID when the entry->router->connection
5435 might not be anymore the most optimal.
5437 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Add route cache for received ID for fast routing.
5441 * Added silc_server_packet_route to route received packet on router
5442 that is not destined to us.
5444 * Renamed silc_server_get_route to silc_server_route_get.
5446 * Added id_string and id_string_len fields into SilcServer to
5447 include encoded ServerID for fast comparing without excess
5448 encoding of the ID's.
5450 * Cleaned up WHOIS command on server side. Added following static
5453 silc_server_command_whois_parse
5454 silc_server_command_whois_check
5455 silc_server_command_whois_send_reply
5456 silc_server_command_whois_from_client
5457 silc_server_command_whois_from_server
5459 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5460 arguments in command replies. All command functions should be
5461 updated to use this macro.
5463 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Minor typo fixes on command reply handling on server.
5467 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Added silc_server_command_add_to_channel internal routine to add
5470 the client to the channel after router has created the channel and
5471 sent command reply to the server.
5473 * Added generic silc_server_send_command to send any command from
5476 * Use static buffer with ID rendering instead of duplicating data.
5478 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Fixed a channel user mode bug when joining to a channel server gave
5481 everybody channel founder rights, oops.
5483 * We mark ourselves as the router of the incoming server connection
5484 if we are router ourselves. This way we can check in some packet
5485 sending functions whether it is locally connected server. For
5486 incoming router connections we put NULL.
5488 * For router sending packets locally means now always sending the
5489 packet cell wide; to local clients and local servers. For normal
5490 server sending packet locally means sending it to only local
5493 * Fixed the JOIN command to really work in router environment. If the
5494 channel is created it is always created by the router. Router is
5495 also responsible of making the initial joining to the channel,
5496 sending JOIN notify to the sending server and distributing
5497 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5498 does not exist server doesn't do anything else but forward the
5499 command to the router which performs everything.
5501 * Added silc_server_send_channel_key function to send the Channel Key
5504 * Added silc_server_create_channel_key to create new channel key. The
5505 channel key is now re-generated everytime someone joins or leaves
5506 a channel, as protocol dictates. Note: channel->key_len is the
5509 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5512 packet_receive.[ch] to separate packet sending and receiving
5513 routines. The server.[ch] now includes everything else including
5514 actual packet processing (writing and reading data) and other
5517 Renamed silc_server_private_message_send_internal to
5518 silc_server_send_private_message. The routine is still though
5519 used only to relay private messages as server does not send
5520 private messages itself.
5522 Renamed silc_server_new_channel to silc_server_create_new_channel
5523 and added new function sicl_server_new_channel that handles the
5524 incoming New Channel packet. Added also new sending function
5525 silc_server_send_new_channel to send New Channel Payload.
5527 * Added new function silc_server_notify to process incoming notify
5528 packet to the server/router. Server may then relay the notify
5529 to clients if needed.
5531 * Added new function silc_server_new_channel_user to process incoming
5532 New Channel User packet. Router will redistribute the packet and
5533 send JOIN notify to its local clients and locally connected servers
5534 if needed. Normal server will send JOIN notify to its local client
5535 on same channel when received this packet. Added also corresponding
5536 sending function silc_server_send_new_channel_user to sent the
5539 * Added boolean route argument to send_notif_to_channel and
5540 packet_send_to_channel functions to attempt to route the packet
5541 if it is TRUE and send only locally if it is FALSE.
5543 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * silc_server_replace_id now broadcasts the received replace ID
5546 packet if it is not broadcast packet already. The router must
5547 broadcast to inform other routers about changed ID.
5549 * Added backpointer to server's router into SilcServer context in
5550 silcd/server_internal.h.
5552 * Fixed silc_server_packet_broadcast to send correct broadcast
5555 * The channel key is now distributed to the local client as soon
5556 as it is received from the router (in router environment) so that
5557 no other packet may be sent for the channel until client has
5560 * silc_server_remove_channel_user now broadcasts the received
5561 Remove Channel User packet if it is not broadcast packet already.
5562 The router must broadcast to inform other routers about removed
5565 * Added users field into SilcPacketContext that is a reference count
5566 of the context. One can increase the reference count by calling
5567 silc_packet_context_dup which is now changed to just increase the
5568 reference count instead of duplicating the data. The reference
5569 count is decresed by calling silc_packet_context_free that will
5570 free the data after the reference count hits zero.
5572 For now on the packet context and everything allocated into it
5573 (including the raw packet from network) must be freed by calling
5574 the new silc_packet_context_free function. Added also new function
5575 silc_packet_context_alloc that must be used now to allocate the
5576 context. This also means that if a routine is asynchronous from
5577 silc_[client/server]_packet_parse_type the packet context must
5578 be duplicated by calling silc_packet_context_dup. Otherwise it
5579 gets free'd after silc_[client/server]_packet_parse_type returns.
5580 Also, one must remember that if packet is duplicated then its
5581 reference count must be decresed by calling the free function as
5582 many times as it was duplicated.
5584 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5585 from both client and server.
5587 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Made joining to a channel working in router environment.
5591 * Cleaned up JOIN command on server side and create function
5592 silc_server_command_join_channel internal routine to make the
5595 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Changed silc_command_pending list to SilcDList. Also, added
5598 `ident' field to SilcServerCommandPending structure to identify
5599 the reply and to call correct callback.
5601 Added silc_server_command_pending_check function to replace the
5602 corresnponding macro. The silc_command_pending list is not
5605 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5606 to set identifier to previously allocated Command Payload. It
5607 is used to set identifier for command when resending Command
5610 * Added silc_command_payload_encode_payload to encode Command
5611 Payload buffer from SilcCommandPayload structure.
5613 * Added silc_argument_payload_encode_payload to encode Argument
5614 payload buffer from SilcArgumentPayload structure.
5616 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Changed WHOIS command to support router connection on server side.
5619 The whois request is always sent to router unless the server is
5620 standalone server. After server has received the reply from the
5621 router will it send the reply to the client.
5623 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5624 broadcast received broadcast packet. The function is used only
5625 by router. The broadcast packet is always sent to the router's
5628 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5629 render given ID to printable string, for log files for example.
5631 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Made basic router to router connections working. At least they
5634 can now connect to each other but nothing really works the way
5635 they are supposed - yet.
5637 * Added new initiator token to RouterConnection configuration
5638 file in silcd/serverconfig.[ch]. It is used to tell whether we
5639 are the initiator to the remote router or whether we'll expect
5640 the other end to connect.
5642 * Moved registering of listener task to silc_server_init, hence
5643 the server starts listenning as soon as it is run, even if it
5644 does not have connections to other routers. Let's see how well
5647 * Changed default connection retry timeouts for more suitable in
5650 * Removed cipher and such arguments from silc_idlist_add_client
5651 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5652 Added new function silc_idlist_add_data to add the keys and stuff
5655 * Added SilcIDListData structure and added it to SilcClientEntry
5656 and SilcServerEntry as their first field in the structure. This
5657 way we can explicitly cast the ID entries to the SilcIDListData
5658 structure and get common data for the entries. In past, we had
5659 to first check what type of connection it is and then cast it to
5660 correct ID entry type. Now, we can directly cast the opaque
5661 pointer to the SilcIDListData (no matter what ID entry it actually
5662 is) and get the data needed.
5664 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5666 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5667 in some circumstances even if threre were timeout tasks, though not
5668 IO tasks, but tasks anyway. Now fixed.
5670 * Defined SilcServerConnection structure to hold connection specific
5671 stuff about directly connected servers and routers. The definition
5672 is currently in silcd/server_internal.h. I thought about having
5673 a bit more important role fro this struct but for now it is used
5674 only when connecting to other server (or router actually).
5676 * Added connecting retry support in server when connecting to
5677 router(s). The retry feature implement exponential backoff
5678 algorithm. Also, added SilcServerParams structure to hold default
5679 parameters for server. For now, it include these retry settings
5680 and are hard coded. After server is moded to be as Silc Server
5681 Library this structure will be more important.
5683 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Changed client librarys channel->clients table to SilcList and
5686 changed code accordingly.
5688 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Changed client's channel table to SilcList and changed code
5691 accordingly. Also changed SilcChannelClientEntry to include back-
5692 pointer to the channel so that client entry can use that structure
5693 as list as well and we have fast cross-reference to the channel.
5694 This change dramatically decreased the complexity of channel
5695 handling with client entry and vice versa (removed one extra
5696 loop when searching for channel entry from many functions).
5698 * Changed server->sim from table to SilcDList and changed code
5701 * NAMES command can now be used from user interface. It will show
5702 the user list on the channel, neatly.
5704 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5705 Code now saves realname of the user if it becomes available.
5707 * Renamed configure.in to configure.in.pre and made ./prepare
5708 script to automatically add correct version string to
5709 configure.in which it creates from configure.in.pre.
5711 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * NAMES command reply now shows users mode with the nickname when
5716 * Moved silc_client_ch[u]mode[_char] functions from
5717 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5718 place sucks, they are utility functions and should be in some
5721 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5723 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5726 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Added TRQ (efficient deque and list library) into lib/trq. This is
5731 a very good list library that is currently used in the SILC. Defined
5732 SilcList API over the library because I didn't like the API very
5733 much. See lib/trq/silclist.h for the API and examples of how to
5734 use the API. Fixed various places in the code to use the new
5735 SilcList API. The SilcList is meant for lists that has a structure
5736 already defined as a list. It is not suitable to add just some
5737 context to the list (in TRQ, the context is the list actually).
5739 So, I defined SilcDList that can be used for the purpose where
5740 predefined list structure does not exit. This can be used as
5741 such list. Now some context just can be added to the SilcDList.
5742 Currently this list is not used in the SILC just yet, though there
5743 are a lot places where this can replace dynamically allocated
5744 tables and I will fix these places, later, to use SilcDList.
5745 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5746 and use TRQ internally).
5748 Also fixed some annoying warning messages that the original TRQ
5749 code generated. Also minor changes to TRQ's Makefile.in.
5751 * Added support for querying by Client ID to both WHOIS and
5752 IDENTIFY commands into server, as required by the protocol.
5754 * Removed method function pointers from SilcBuffer structure. They
5755 weren't used to anything and just increased the context size for
5756 no good reason. This change also made silc_buffer_alloc and
5757 silc_buffer_free functions inline functions.
5759 * Disabled command flooding detection support until it's fixed so
5760 that it accepts commands in but does not execute them more than once
5763 * Added silc_net_localhost(), to return local hostname, into
5764 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5765 that must be initialized before calling silc_client_init.
5767 * Added new function: silc_server_send_notify_on_channels to send
5768 notify messages to all channels client has joined. It is assured
5769 that the message is sent only once per client.
5771 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5772 lib/silcutil/silcutil.[ch] as silc_format function. The new
5773 function is generic and is used by server as well, not only by
5774 the logging routines.
5776 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5777 the provided version string was not acceptable. Added new function:
5778 silc_ske_check_version into lib/silcske/silcske.h. The function
5779 must be implemented by the application (client or server) and it
5780 does not reside in the SKE library. The function checks the version
5781 string remote end sent.
5783 * Added back pointers (to opaque context and to SilcSocketConnection)
5784 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5786 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5787 duplicate packet context structure.
5789 * Changed `notify' client operation to send same arguments as client
5790 receives from server except for ID's. ID's are mapped to correct
5791 ID entry and that is returned. Also, if channel entry is not sent
5792 by server but the notify is for channel the channel entry is sent
5793 to application (otherwise application doesn't know that it is for
5794 channel (library gets it from packet's Destination ID)).
5796 * Added silc_client_remove_from_channels into client library to
5797 remove a client from all channels it has joined to. Used when
5798 received SIGNOFF notify from server. Added also new function
5799 silc_client_replace_from_channels to replace old ID entry with
5800 new ID entry on all channels. Used when received NICK_CHANGE
5803 * Fixed ID Cache list handling in silc_idlist_get_client in
5804 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5805 to get (or query) client by ID.
5807 * Updated TODO list.
5809 * Added connection authentication status message defined by the
5810 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5811 support for these into the code in client and server side.
5813 * Added generic function silc_client_send_command to send any command
5814 with variable argument list. Application should use this function
5815 to send commands if the command functions provided by the library
5816 does not suite for the application's user interface needs.
5818 * Added new `failure' client operation. Application is notified about
5819 received failure packet if client is executing a protocol. In this
5820 case the protocol's execution has failed.
5822 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5823 is required by the protocol.
5825 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5826 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5829 * Added status flag to SilcSKE object to indicate realtime status
5830 of the SKE protocol.
5832 * Application receives now exactly same command reply arguments as
5833 the library receives from server. However, if ID is received the
5834 corresponding ID entry is returned to the application (eg. Client
5835 ID is mapped to correct SilcClientEntry entry and that is returned).
5836 Changed command_reply client operation due to this change.
5838 * Changed all ID's in commands and in command replys as ID Payloads.
5839 Change affected both client and server side codes.
5841 All ID's sent in SILC network (with execption of ID's in SILC
5842 Packet header) are sent in ID Payload to support variable length
5845 * Server now notifies nick changes and notifies all clients on
5846 the channels about the new nickname (about the new Client ID,
5849 * Implemented CMODE command to change channel modes. Supports all
5850 channel modes defined by the protocol specs except ban and invite
5851 lists. (Also, private channel key mode is supported but support for
5852 setting private channel key in client is missing, thus, this mode
5853 has no effect on client side (except that server requires that the
5854 client uses private channel key and normal channel traffic does not
5857 Also, invite mode works per se, but INVITE command does not work
5858 yet correctly, so you can set channel as invite only channel but
5859 inviting clients to the channel does not work (it is yet to be
5860 thought what's the best way to do it).
5862 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5863 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5864 Implemented CUMODE command to change user's mode on the channel.
5865 Supports all modes defined by the protocol specs.
5867 * Added NAMES command reply to return users modes on the channel.
5869 * Removed unnecessary and slow ciphers from lib/silccrypt.
5871 * Set SO_KEEPALIVE option to connection sockets by default.
5873 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5875 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5876 redefined the Notify Payload into protocol specs.
5878 * Added silc_id_payload_parse_id to get ID directly from raw
5881 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5884 accept searching by Client ID as well.
5886 * Added support for LEAVE and SIGNOFF notify types in client library.
5888 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5889 to parse ID Payload from raw data.
5891 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Added flags parameter into silc_ske_assemble_security_properties
5894 function in lib/silcske/silcske.[ch].
5896 * Changed notify client operation to fit better for notify messages
5897 sent by server. The notify payload received from server is now
5898 passed to the application (after parsing it to SilcNotifyPayload).
5899 It is application's responsibility to retrieve the arguments
5900 from the payload and show the message the way it wants. The message
5901 sent by server is implementation specific.
5903 * Changed public keys to comply with the protocol specification.
5904 Old public keys are not supported anymore and are not compatible.
5906 * Removed nickname from Channel Payload as the latest draft removed
5907 it. The client must resolve the nickname from the NAMES command
5908 reply received when it joined the channel.
5910 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5912 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Fixed some errors in protocol specification drafts.
5916 * Created lib/silccore/silcnotify.c to implement Notify Payload
5917 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5918 generic payloads described by protocol specifications. The file
5919 includes implementations for ID Payload and Argument Payload.
5921 * Changed Command Payload implementation to use the new Argument
5922 Payload. Changed command_xxxx_payload to command_payload_xxxx
5923 to comply with SILC coding conventions.
5925 * Added suppport for Argument Payload handling in Notify Payload
5926 implementation as protocol requires it. Added the new support
5927 into server and client lib as well.
5929 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added support for multiple nicknames on same channel. [n] is
5932 added locally to the nickname if there are more than one same
5933 nicknames on the channel.
5935 * Server now sends all nicknames that matched WHOIS request.
5936 Client also shows the list received from server.
5938 * Added TOPIC command to client side. User can now set and show
5939 current topic on channel.
5941 * Added MOTD command to client and server. Also, server sends the
5942 motd when client connects to the server.
5944 * Changed version strings to comply ISO 8601.
5946 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Fixed protocol error handling in client library. It should now
5949 cope even if the SKE fails for some reason.
5951 * Made new protocol specification drafts for submitting to IETF.
5953 * Implemented TOPIC command to server in silcd/command.c.
5955 * Added two new notify types into lib/silccore/silcnotify.h:
5956 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5957 notify nickname change and topic setting/change on a channel.
5959 * API change of command_reply operation in client library. The
5960 application gets now the status type received from server as well.
5962 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5966 * Cras fixed and optimized the packet handling even further and
5967 it should work now. Minor change to the prototype of function
5968 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5970 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Added new function into lib/silcutil/silcschedule.[ch]:
5973 silc_schedule_with_fd to select() a specified fd. The function
5974 returns after timeout expires or data arrives or goes. The
5975 function is used by packet routines to wait that all data is
5976 received from network.
5978 * Fixed data reading from network in lib/silccore/silcpacket.c.
5979 The code now assures that all data is read from the fd and then
5980 continues packet processing. This was a bug fix since the code
5981 used to drop some data in some circumstances.
5983 * Added new function into lib/silcclient/client.[ch]:
5984 silc_client_start_key_exchange to start key exchange after
5985 connection has been established to server. The code internally
5986 now uses this funtion but its main purpose was to provide it
5987 for applications that perform their own connecting. After
5988 application has created a connection it merely calls this
5989 function to start the key exchange between client and server.
5990 The library takes care of everything else after that.
5992 Updated also lib/silcclient/README to explain the usage of
5995 * Do not send to application information that connection has
5996 been established. Application gets notified it by connect
5999 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Applied cras's patch to add silc_schedule_one function. The
6002 function runs scheduler once and returns.
6004 * Fixed the scheduler after cras messed it up. The timeout
6005 handling works now as it's supposed to work.
6007 * Added into lib/silccore/ silcnotify.h to include notify
6008 message types support. Changed silc_server_send_notify*
6009 functions, in server.[ch], to support those new notify types.
6010 Added the support for the notify types into client library,
6011 as well. Added new notify client operation into ops.h in
6014 * Changed silc_server_packet_send_to_channel to send normal
6015 packets instead of just channel message packets. The function
6016 is now used to send the notify packets to channels. It is not
6017 used to send channel message packets anymore, as server never
6020 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6021 va_arg()s as it seems to require it nowadays. I guess, if SILC
6022 is compiled with older va_arg() the new code should work anyway.
6024 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Splitted core library. Core library (lib/silccore) includes
6027 now only SILC protocol specific core (and common) components.
6028 Created new utility library (lib/silcutil) that includes more
6029 generic purpose stuff. The stuff for util library was taken
6030 from the old core library. This was minor and easy split.
6032 * Created SILC Client Library (lib/silcclient) that includes
6033 implementation of the SILC client without user interface. This
6034 was major move from silc/ directory. The code has been changed
6035 so that it is transparent towards the user interface. The
6036 silc/ directory includes now the same user interface as before
6037 and it uses the new client library. Read lib/silcclient/README.
6038 Basicly, the client library performs everything else related
6039 to SILC except user interface handling. Also, configuration
6040 files are considered to be part of user interface and library
6041 does not handle them.
6043 This change also changed a lot of structures, function naming etc.
6044 Most important change was that SilcClientWindow object was
6045 renamed to SilcClientConnection in the client library. Created
6046 also new file lib/silcclient/ops.h. Also added new files
6047 silc/local_command.[ch] and silc/client_ops.[ch].
6049 All these changes were made to make it easier for user interface
6050 designers to create what ever user interface for the SILC client
6053 It is also expected that the server will be moved to lib
6054 directory as well and SILC Server Library will be created;
6055 sometimes in the future.
6057 * Removed Local commands from lib/silccore/silccommand.h as
6058 they are application specific and new client library does not
6059 handle any of those anymore.
6061 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6062 old client implementation in silc/.
6064 * Added support for callback functions in SILC_LOG_* macros.
6065 Application can now set its own callbacks that will be called
6066 instead of using the default functions that will always print
6067 the debug messages to stderr (or stdout). Also, debugging can
6068 now be disabled by setting silc_debug to FALSE and re-enabled by
6069 setting it to TRUE. Note, that logging will still work even
6070 if debugging is disabled.
6072 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6073 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6074 silc_log_reset_debug_callbacks.
6076 * To enable debugging in silc client one must give now -d
6077 option on command line.
6079 * Changed silc_schedule_init to automatically allocate task queues
6080 if they are not allocated before calling it.
6082 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * Added GMP 3.1 into math library.
6086 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6089 a channel in SILC network. The packet is used by servers and
6090 routers to notify other routers that user has left a channel.
6091 This little feature was missing until now. Added the feature
6092 to protocol specification as well.
6094 Added functions: silc_server_send_remove_channel_user and
6095 silc_server_remove_channel_user into server.[ch].
6097 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6098 lib/silccore/silcpacket.h. However, they are not implemented
6101 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6103 * Fixed joining to a channel and sending channel messages
6104 between server and router. The channel message sending should
6105 now work inside a cell.
6107 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * Fixed the private message sending between server and router.
6110 The private message sending should now work inside a cell.
6112 * Added silc_server_replace_id into server.[ch] to replace
6113 existing ID in the SILC network.
6115 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6116 and silc_idlist_replace_server_id into idlist.[ch] in server.
6118 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Fixed the server to server connections. Server can again now
6121 connect to router. Router to router connections probably does
6124 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Added dynamic protocol registering support. Now protocols can
6127 registered and unregistered on the fly. Patch by cras.
6129 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Added lib/contrib directory to hold routines that some platforms
6132 don't have but are needed by SILC.
6134 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6135 into lin/contrib to provide getopt() and getopt_long() for
6136 those who don't have it.
6138 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added AWAY command to client. When away message is set and
6141 client receives a private message packet the client automatically
6142 replies to the sender with the away message.
6144 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6145 bug seemed to be the cause of recent problems when compiling
6148 * Added version detection support to SKE protocol specification
6149 and added the new changes to the SKE implementation as well.
6150 There were other minor changes in the SKE protocol as well.
6152 Many changes in lib/silcske/silcske.[ch] and in
6153 lib/silcske/payload.[ch].
6155 * Added ^U functionality, clear input line. Patch from cras.
6157 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Mainly small bugfixes on core library. Fixed some debugging
6160 logging and buffer overflow in silclog.c.
6162 * Updated config.sub and config.guess on the distribution tree.
6164 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Added command lagging support in server. Client may execute
6167 commands now only once in two seconds.
6169 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Optimized packet reception. MAC computation and checking is now
6172 also more optimized. A lot previously duplicated code is now
6173 used as generic by both client and server.
6175 * Fixed key pair generation in clientutil.c
6177 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added into lib/silccore/silcbufutil.[ch] new function;
6180 silc_buffer_realloc.
6182 * Moved generic packet sending/encryption functions to
6183 lib/silccore/silcpacket.[ch] from client and server. Some
6184 rewriting of the functions.
6186 * Moved all generic packet reception/decryption functions to
6187 lib/silccore/silcpacket.[ch] from client and server. The
6188 packet processing is now much cleaner in both client and server.
6189 These were major changes in both client and server.
6191 * Created many common functions in server to do packet sending.
6192 Previously code were duplicated a lot, this has been removed
6195 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Rewrote major parts of the ID cache system. Don't know
6198 whether it is better now or not but at least the API is more
6201 * Major rewrite on ID cache stuff on client because of the ID
6202 cache API changes. Added idlist.c to client.
6204 * Also major rewrite on ID cache stuff on server as well.
6205 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6206 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6207 in hand, instead they are all put into the ID cache system now.
6208 All server_idlist_* routines uses ID cache now instead of
6209 traversing its own lists (those lists does not exist anymore).
6210 SilcIDList though still exists. Also, SilcXXXEntry's are
6213 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Finally made the SKE implementation compliant to the protocol
6216 specification. All mp integers are now binary encoded as
6217 opposed being HEX encoded.
6219 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6222 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6223 functions: silc_[encode/decode]_pem. Also added function
6224 silc_encode_pem_file to PEM encode with newlines ('\n') for
6227 * SILC public keys are now encoded either PEM or binary. Same
6228 option is for private keys as well. By default private keys
6229 are binary encoded and public keys PEM encoded. Silly HEX
6230 encoding were removed.
6232 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6233 function to create fingerprints.
6235 * Fixed a bug in SHA1; does not change the original data anymore.
6237 * Partly implemented INFO command on client and server side.
6238 Fixed CLEAR command. Changes to SERVER command; show current
6239 server(s) when giving command without arguments. Added
6240 VERSION command to client.
6242 * Added check to server that unregistered connections cannot
6243 execute commands (unless it is specificly allowed).
6245 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Fixed screen refresh.
6249 * Fixed channel joining bug from client. On some circumstances
6250 client tried to join to a channel it had already joined.
6252 * Added public key verification process into client's protocol.c.
6253 The client now verifies the public key from user and saves
6254 it into ~./silc/serverkeys/ directory.
6256 Added into: clientutil.[ch]: silc_client_verify_server_key.
6258 * Changed SKE protocol's silc_ske_initiator_finish function
6259 to accept callback function that verifies the received public
6260 key. Removed old silc_ske_verify_public_key function.
6262 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6264 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6265 silc_pkcs_private_key[_data]_set.
6267 * Made the password and public authentication more cleaner in
6268 server's protocol.c.
6270 * Removed historic and obsolete protocol `channel_auth' from
6271 both client and server.
6273 * Removed wrong way of sending command status messages from
6274 server to client in server's command.c. The old way violated
6275 protocol specification.
6277 Changes to silccore/silccommand.[ch]: removed
6278 silc_command_encode_status_payload -> not needed anymore,
6279 changed silc_command_encode_payload_va to accept extra
6280 argument on variable argument list. The argument type must
6281 now be provided to the function. Also, added new function:
6282 silc_command_encode_reply_payload_va which is same as
6283 normal command_encode_payload_va except command status type
6284 is provided as extra argument.
6286 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Added ~./silc directory handling. The directory includes the
6289 public and private keys for the client.
6291 Added silc_client_check_silc_dir, silc_client_create_identifier
6292 and silc_client_load_keys.
6294 * Implemented SILC protocol compliant public key. Added public
6295 and private key saving to and loading from files.
6297 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6298 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6299 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6300 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6301 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6303 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6304 silc_pkcs_load_[public/private]_key.
6306 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Added silc_server_get_route (route.[ch]) to get connection
6309 data for the fastest route for given ID.
6311 * Implemented INVITE command on client and server. The command
6312 were re-defined in the SILC Protocol Specification and the
6313 implementation now complies with the specification.
6315 * Implemented PING command on client and server.
6317 * Implemented NAMES command on client and server. The server side
6318 supports currently only normal server not router server yet.
6319 Some changes to NAMES definition in SILC protocol specification.
6321 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Implemented LEAVE command on client and server.
6325 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6326 again. This change was made to the protocol as well. Server
6327 should not violate the protocol specification anymore.
6329 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6332 was tested. SOCKS4 was not but should work anyway.
