3 * If we are normal server, and we've not resolved client info
4 in WHOIS or IDENTIFY from router, and it is global client,
5 we'll check whether it is on some channel. If it is not
6 then we cannot be sure about its validity and will resolve it
7 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
10 * Search channel by name (if possible) rather than by ID
11 in IDENTIFY command's command reply. Affected file is
12 silcd/command_reply.c.
14 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
16 * Distribute to the channel passphrase in CMODE_CHANGE notify.
17 Updated specs and implemented it. Affected file silcd/command.c,
18 silcd/packet_send.c and silcd/packet_receive.c.
20 * Implemented the <founder auth> payload handling in the JOIN
21 command. If provided all conditions for channel joining
22 except requirement to provide correct passphrase can be
23 overrided by the channel founder. Updated the protocol specs.
24 Affected file silcd/command.c.
26 Added support for founder auth in JOIN command in client
27 library. Fixed the parsing of the JOIN command now to support
28 all options as they should be. The affected file is
29 lib/silcclient/command.c.
31 * Optimized the WHOIS and IDENTIFY commands to send the request
32 to router only if it includes nicknames or other names. If
33 they include only IDs then check the local cache first before
34 routing. Affected file is silcd/command.c.
36 * Added channels topic announcements. Affected file is
37 silcd/packet_receive.c and silcd/server.c.
39 * Fixed the silc_server_send_notify_topic_set to really destine
40 the packet to channel. Affected file silcd/packet_send.c.
42 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
43 library. Affected file lib/silcclient/client_notify.c.
45 * Added UMODE announcements. Affected file silcd/server.c.

49 * Memory leak fixes in:
51 lib/silcutil/silcsockconn.c
55 lib/silccrypt/silcpkcs.c
56 lib/silccore/silccommand.c
57 lib/silccore/silcidcache.c
62 * ROBOdoc documented the lib/silcske/groups.h file and a
63 bit changed the interface for better.
65 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
67 * Update the client entry context in the ID cache after
68 nick change. Affected file lib/silcclient/command.c.
69 Fixes the CUMODE command when regaining founder privileges,
70 and a little WHOIS problem.
72 * Fixed silc_net_gethostbyname to correctly call the
73 inet_ntop. Affected file lib/silcutil/silcnet.c.
75 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
77 * Added IPv6 support checking to the configure.in.pre, added
78 also --enable-ipv6 option to override the check. Affected
79 file configure.in.pre.
81 * The silc_thread_create now calls the start function
82 directly if threads support is not compiled in. Removes
83 ugly #ifdef's from generic code. Affected files are
84 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
86 * Added silc_net_gethostby[name/addr]_async to asynchronously

98 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
99 routines. Added silc_net_is_ip[4/6]. Affected file is
100 lib/silcutil/unix/silcunixnet.c. All routines that take
101 address as argument now supports both IPv4 and IPv6 addresses.
103 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
105 * Fixed LIST command reply sending in server. Affected file
108 * Server now sends the kicker's client ID in the KICK notify
109 to the kicked client. Affected file silcd/command.c.
111 * The client library now parses the kickers client ID and
112 UI displays it. Affected files lib/silcclient/client_notify.c
113 and irssi/src/silc/core/silc-channels.c, module-formats.c.
115 * Made all payload parsing function prototypes consistent.
116 They all take now const unsigned char * and uint32 pair as
117 the payload data instead of SilcBuffer. Changes all around
118 the source tree. Other unsigned char* -> const unsigned char*
119 changes around the tree as well.
121 * Optimized SFTP client and server packet sending not to
122 allocate new buffer for each packet but to recycle the
123 first allocated buffer. Affected files are
124 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
126 * Optimized the SFTP client to use SilcList instead of
127 SilcDList for requests, because it is faster. Affected file
128 is lib/silcsftp/sftp_client.c.
130 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
131 into lib/silccore/silcid.[ch].
133 Renamed silcpayload.[ch] into silcargument.[ch].
135 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
137 * If client entry is deleted with active key agreement
138 session, abort the session.
140 The silc_client_abort_key_agreement now calls the completion
141 callback with new SILC_KEY_AGREEMENT_ABORTED status.
143 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
146 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
148 * Don't use __restrict in older GCC's. Affected file is
149 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
151 * silc_net_localhost now attempts to reverse lookup the
152 IP/hostname. Affected file lib/silcutil/silcnet.c.
154 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
155 command. It can be used to gain founder privileges at
156 the same time when joining the channel.
158 Defined that the SILC_NOTIFY_TYPE_KICKED send the
159 kicker's client ID as well. Updated protocol specs.
161 Defined that the server must send SILC_COMMAND_IDENTIFY
162 command reply with error status to client who sent
163 private message with invalid client ID.
165 Updated the protocol specification.
167 * Added silc_server_send_command_reply to send any
168 command reply. Affected file silcd/packet_send.[ch].
170 * Added silc_id_payload_encode_data to encode ID payload
171 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
173 * The server now send IDENTIFY command reply with error
174 status if client ID in private message is invalid. Affected
175 file silcd/packet_receive.c.
177 * Save the server key file with server's IP address in
178 the filename instead of hostname. The affected file is
179 irssi/src/silc/core/client_ops.c.
181 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
183 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
186 * Added libtool support for compiling shared objects in
187 lib/silcsim. Affected file configure.in.pre and
188 lib/silcsim/Makefile.am. Original patch by cras.
190 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
192 * Pid file configuration, and server's config file fixes
193 patch by toma. Updated CREDITS file.
195 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed silc_client_channel_message to not try to decrypt
198 the message twice if it resolved the destination client
199 information. This could cause of dropping one channel
200 message. Affected file lib/silcclient/client_channel.c.
202 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
204 * Added silc_client_run_one into lib/silcclient/silcapi.h and
205 lib/silcclient/client.c. This function is used when the SILC
206 Client is run under some other scheduler, or event loop or
207 main loop. On GUI applications, for example this may be
208 desired to used to run the client under the GUI application's
209 main loop. Typically the GUI application would register an
210 idle task that calls this function multiple times in a second
211 to quickly process the SILC specific data.
213 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
215 * Fixed silc_server_drop() for dropping the supplementary
216 groups as well, this could cause a security hole on some
219 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
221 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

225 to run server on foreground. A patch by debolaz.
226 Affected files silcd/server.c, silcd/silcd.c.
228 * Fixed MOTD to return the MOTD file server name. Affected
229 file silcd/command.c.
231 * Added INFO command reply handling to the Irssi SILC Client.
232 Affected file irssi/src/silc/core/client_ops.c.
234 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
236 * Fixed the silc_idcache_list_* routines to really support
237 the dynamic list. Fixes a crash. Affected file is
238 lib/silccore/silcidcache.c.
240 * Fixed the LIST command reply to really call LIST command's
241 pending callbacks. Affected file silcd/command_reply.c.
243 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
245 * Update conn->local_entry->nickname after giving NICK
246 command. Affected file lib/silcclient/command.c.
248 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
250 * Added the [pid] option to the silcd configuration file
252 Affected files: serverconfig.[ch] and silcd.c

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

596 Affected files lib/silcclient/silcapi.h and
597 lib/silcclient/client_ftp.c.
599 * Check that newsize in silc_buffer_realloc is larger than
600 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
602 * Added better monitor of file transfers. It now monitors
603 key agreement protocol during the file transfer too. Added
604 error reporting too. Affected files
605 irssi/src/silc/core/silc-servers.c,
606 irssi/src/fe-common/silc/module-formats.[ch].
608 * Wrote a help file for FILE command.
610 * Added silc_rng_global_get_byte_fast to get not-so-secure
611 random data as fast as possible. Random data is read from
612 /dev/urandom if available and from the SILC RNG if not
613 available. It is used in padding generation. Affected file
614 lib/silccrypt/silcrng.[ch].
616 * All packets in client library are now processed synchronously.
617 Optimized packet processing a lot. Affected file
618 lib/silcclient/client.c.

621 now in server, to optimize packet processing. Affected file
624 * Include files are installed now only in Toolkit distribution
625 if make install is given. Affected files: all Makefile.am's.
627 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Assure that silc_client_notify_by_server_resolve does not
630 resolve the client information multiple times. If it cannot
631 be found by the first it cannot be found at all. Affected
632 file lib/silcclient/client_notify.c.
634 * Fixed WHOWAS command reply calling. Affected file
635 lib/silcclient/command_reply.c.
637 * Removed all references to silc_idlist_get_client from the
638 Irssi SILC client since that call is internal call used by
639 the library. The Irssi SILC client will use now client
640 retrieval functions found in silcapi.h.
642 * Fixed a bug in resolving nickname info before sending
643 private message. It used freed memory. Affected file
644 irssi/src/silc/core/silc-servers.c.
646 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

666 Affected file lib/silcutil/silcnet.[ch].
668 * If key exchange or rekey protocol is active for a connection
669 parse all packets syncronously since there might be packets
670 in packet queue that we are not able to process without first
671 processing packets before them. Affected file silcd/server,
672 lib/silcclient/client.c.
674 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
675 whether library should continue processing the packet.
676 Affected file lib/silccore/silcpacket.h.

707 lib/silcutil/silcutil.[ch].
709 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
711 * Resolve the client info when received private message or
712 channel message for a client which nickname we don't know.
713 Affected files lib/silcclient/client_prvmsg.c and
714 lib/silcclient/client_channel.c.
716 * Do not crash in /KEY if client is not connected. Affected
717 file irssi/src/silc/core/silc-channels.c.
719 * Added SilcClientStatus field to the SilcClientEntry in the
720 lib/silcclient/idlist.h.
722 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
723 is incomplete and is being resolved, it won't be resolved
726 Make sure also that USERS command reply does not resolve
727 twice information. Affected file is
728 lib/silcclient/command_reply.c.
730 Make sure that silc_client_get_clients_by_list does not
731 resolve twice same information.
733 * Check for valid client->id in the silc_server_free_client_data.
734 Affected file silcd/server.c.
736 * Fixed /GETKEY nick@server not to crash if the server entry
737 is not found. Affected file lib/silcclient/command.c.
739 * Fixed the silc_server_check_cmode_rights to check the
740 requested modes correctly. Affected file silcd/command.c.

744 * Better checks for non-printable chars in nick added.
745 Affected file silcd/command.c.
747 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
749 * Call the silc_server_udpate_servers_by_server in the
750 primary router that comes back online in the backup resuming
751 protocol. Otherwise it routes packets wrong. Affected file
752 silcd/server_util.[ch], silcd/server_backup.c.
754 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
757 lib/silcutil/silcbuffmt.[ch].
759 * Redefined the SILC packet header to include the padding
760 length. Affected file lib/silccore/silcpacket.[ch].
762 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
763 length for maximum padding up to 128 bytes). Affected
764 file lib/silccore/silcpacket.h.
766 * Removed all backwards support for old 0.5.x MAC thingies.
767 The SILC packet header change makes it impossible to be
768 backwards compatible.
770 * Send the ENDING packet with timeout in the backup resuming
771 protocol. This is to assure that all routers has connected
772 to the primary router. Affected file silcd/server_backup.c.
774 * Changed the RNG to take the first IV from random data. It
775 used to take it from zero actually. Changed the RNG also
776 to use /dev/urandom during session. /dev/random is used
777 in initialization. Affected file lib/silccrypt/silcrng.[ch].
779 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
781 * Changed the SILC packet header to have the first two bytes
782 (the packet length) encrypted. Affected files aroung the
783 code tree, lib/silccore/silcpacket.[ch]. Removed the
784 SilcPacketCheckDecrypt callback. It is not needed anymore
785 since the silc_packet_receive_process will determine now
786 whether the packet is normal or special.
788 * Implemented the unidirectional MAC keys. Affected files
789 lib/silcske/silcske.c, silcd/protocol.c and
790 lib/silcclient/protocol.c.
792 * Implemented the packet sequence number to the MAC computation.
793 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
794 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
795 lib/silcclient/protocol.c.
797 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Allow backup router to announce servers. All servers
800 announced by backup router are added to the global list
801 automatically. Update hte server's socket to our primary
802 router also when backup router announces a server.
803 Affected file silcd/packet_receive.c.
805 * Do not update the client->router in the function
806 silc_server_udpate_clients_by_server if the client is on
807 global list. We might fail to find any specific server
808 for locally connected clients and local cell clients. They
809 should still use the `from' and not `to' as client->router.
810 This fixes backup router resuming protocol. Affected file
813 * Decrease channel statistics count only if the channel
814 deletion worked. Affected files are silcd/server.c and
817 * Added silc_server_update_servers_by_server to update origin
818 of all server entries. Used during backup router protocol.
819 Affected files silcd/server_util.[ch], silcd/server.c. and
820 silcd/backup_router.c.
822 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
823 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
824 silc_hmac_get_hash and silc_hmac_get_name. Affected file
825 lib/silccrypt/silchmac.c.
827 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Assure that router cannot reroute the same channel message
830 to the sender. Affected file silcd/packet_receive.c.
832 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Made better checks that the channel message is not sent
835 to the router it came from. Affected file is
836 silcd/packet_send.c. Fixed memory leak too.
838 * Announce informations for incoming router connection, but
839 only after checking if it is replaced by backup router.
840 Affected file silcd/packet_receive.c.
842 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
844 * Fixed the backup resuming protocol to work in multiple
845 router environment. Affected file silcd/server_backup.c.
847 * Route packet only to one router in the function
848 silc_server_packet_send_to_channel. Affected file is
851 * Fixed silc_server_send_notify_dest to set the broadcast
852 flag. Fixed the silc_server_send_notify_topic to actually
853 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
854 Affected file silcd/packet_send.c.
856 * Changed the SFTP Filesystem interface. Changed the
857 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
858 the filesystem operation function. The SilcSFTPFilesystem
859 is now a context that is allocated by all filesystem allocation
860 functions and it already includes the operations structure
861 and filesystem specific context. It is given as argument
862 now to the silc_sftp_server_start. This made the interface
863 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
864 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
866 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
868 * Changed the backup router adding and getting interfaces
869 in the server. The router that will be replaced by the
870 specified backup router is now sent as argument. Affected
871 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
874 * Added silc_net_addr2bin_ne to return the binary form of
875 the IP address in network byte order. Affected files
876 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
878 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Check for existing server ID in silc_server_new_server
881 and in silc_server_connect_to_router_final and remove the
882 old entry if it exists. Affected file silcd/packet_receive.c,
885 * Send the channel message always to only one router, either
886 in upstream or downstream. Affected file is
889 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

920 send any data. Affected file silcd/packet_send.c.
922 * Assure that if outgoing data buffer is pending do not force
923 send any data. Affected file lib/silcclient/client.c.
925 * Implemented the backup router support when the primary router
926 goes down. The servers and routers can now use the backup
927 router as new primary router without loosing connectivity.
929 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
932 in the server to indicate disabled entry. All data read
933 from the connection will be ignored and no data is sent
934 for entry that is disabled. Affected files are
935 silcd/idlist.h, silcd/server.c.
937 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Created SFTP client and server test programs in the
940 lib/silcsftp/tests directory.
942 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
944 * Implemented memory filesystem (virtual filesystem) for
945 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
948 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Implemented the SFTP (SSH File Transfer Protocol) to the
951 lib/silcsftp. It includes SFTP client and SFTP server
954 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Moved lib/silccore/silcprotocol.[ch] to the
957 lib/silcutil library.
959 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
960 take variable argument list pointer as argument. Affected
961 file lib/silcutil/silcbuffmt.[ch].
963 * Added silc_buffer_set function that is used to set data
964 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
965 Affected file lib/silcutil/silcbuffer.h.
967 * Changed various routines in the core library to use the new
968 silc_buffer_set instead of allocating new buffer only for
971 * Added 64-bit value formatting and unformatting support to the
972 silc_buffer_[un]format routines. Affected file is
973 lib/silcutil/silcbuffmt.[ch].
975 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
976 to includes/bitmove.h.
978 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
980 * Fixed channel user mode saving in client library. Affected
981 file lib/silcclient/command[_reply].c.
983 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
985 * Defined the file transfer to the SILC Protocol. Added
986 new packet type SILC_PACKET_FTP and defined File Transfer
987 Payload. The mandatory file transfer protocol is SFTP
988 (SSH File Transfer Protocol). Affected file in addition
989 of the internet draft is lib/silccore/silcpacket.h.
991 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
992 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
993 is used as part of backup router protocol when the primary
994 router of the cell is back online and wishes to resume
995 the position as primary router.
997 * Redefined the MAC generation keys in the protocol. The
998 same key is not used anymore in both direction. Both
999 direction will now use different keys for sending and
1000 receiving. This fixes a potential security flaw. This
1001 change causes incompatibilities in the protocol.
1003 * Redefined also the MAC computation from the packet.
1004 An packet sequence number is now added to the MAC
1005 computation. This prevents possible replay attacks against
1006 the protocol. This change too causes incompatibilities
1009 Added `sequence' field to the SilcPacketContext to hold
1010 the current sequence number for the packet.
1012 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Added `created' field to the SilcIDListData in the file
1015 silcd/idlist.h to indicate the time when the entry was
1018 * Added `created' field to the SilcChannelEntry too. Affected
1019 file silcd/idlist.h.
1021 * Added `creation_time' aguments to all the announcement functions
1022 in the server. If it is provided then only the entries that
1023 was created after the provided time frame are actually
1024 announced. Affected file silcd/server.[ch].
1026 * The protocol says that the Channel ID's IP address must be
1027 based on the router's IP address. Added check for this in
1028 the silc_server_new_channel when processing incoming New Channel
1029 Payload. Affected file silcd/packet_receive.c.
1031 * Print out the correct version with --version in SILC client.
1032 Affected file irssi/src/silc/core/silc-core.c.
1034 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1037 entry always, not just when the command is coming from client.
1038 Affected file silcd/command.c.
1040 * Added new function silc_server_packet_queue_purge to purge the
1041 outgoing data queue to the network. After the function returns
1042 it is guaranteed that the outgoing packet queue is empty.
1043 Affected file silcd/packet_send.[ch].
1045 * Purge the outgoing packet queue in the rekey protocol's final
1046 callback to assure that all rekey packets go to the network
1047 before quitting the protocol. Affected file silcd/server.c.
1049 * Added silc_client_packet_queue_parse as similar function as
1050 in server to the client library. The affected file is
1051 lib/silcclient/client.c.
1053 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Splitted silcd/server.c and created silcd/server_util.[ch]
1056 for utility functions.
1058 * Added new socket flag SILC_SF_DISABLED to indicate that the
1059 connection is open but nothing can be sent to or received from
1060 the connection. Affected file lib/silcutil/silsockconn.[ch].
1061 The checking for disabled socket is checked in the low level
1062 silc_socket_write and silc_socket_read functions.
1064 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Allow only nicknames and channel names that fits into the
1067 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1069 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * When processing JOIN command reply in server check that if
1072 the channel exists in our global list we'll move it the local
1073 list. Affected file silcd/command_reply.c.
1075 * Fixed the check whether client is joined on the channel already
1076 in JOIN command. Affected file lib/silcclient/command.c.
1078 * Fixed the JOIN command reply to check whether the channel
1079 already exists. Affected file lib/silcclient/command_reply.c.
1081 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * Added silc_ske_status_string to map the SKE error numbers
1084 to readable strings. The affected files are
1085 lib/silcske/silcske[_status].[ch].
1087 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Do not show the private channels on the WHOIS channel list
1090 as it is not allowed by the protocol. The affected file is
1093 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Assure that the packet length digged from the actual packet
1096 is something sensible in the silc_packet_decrypt_rest_special
1097 in lib/silccrypt/silcpacket.c.
1099 * Free and NULL the allocated pointer in silc_hmac_alloc if
1100 the HMAC allocation fails. The affected file is
1101 lib/silccrypt/silchmac.c.
1103 * Print the selected security properties to the log files in
1104 the server. Affected file silcd/protocol.c.
1106 * Add SKE's reference counter even if calling the completion
1107 callback manually. Otherwise it goes negative, although it
1108 does not cause any problems. The affected file is
1109 lib/silcske/silcske.c.
1111 * Remove the client entry with short timeout after giving the
1112 KILL command. Affected file lib/silcclient/command.c.

1115 case all found clients are already disconnected (WHOWAS would
1116 found them) in the server. Affected file silcd/command.c.
1118 * Update the last_receive (time of last data received) to be
1119 updated only when received private or channel message so that
1120 the idle time showed in WHOIS makes more sense.
1122 * Added boolean field `valid' in to the SilcClientEntry in the
1123 client library to indicate whether the entry is valid or not.
1124 This fixes the nickname change bug on channel when changing
1125 the nickname to be same than the old (like nick to Nick) the
1126 nickname formatter doesn't set the new nick anymore to Nick@host.
1127 Affected file lib/silcclient/idlist.[ch].
1129 * Now actually fixed the nickname changing on disconnection.
1130 Added new function silc_change_nick to the Irssi SILC Client.
1131 Affected file irssi/src/silc/core/client_ops.c,
1132 irssi/src/silc/core/silc-nicklist.[ch].
1134 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1136 * Check that the public key exists in the GETKEY command before
1137 trying to encode it. Affected file silcd/command.c.
1139 * Print some notifications on received public keys with GETKEY
1140 command in the Irssi SILC Client. Affected files are
1141 irssi/src/fe-common/silc/module-formats.[ch],
1142 irssi/src/silc/core/client_ops.c.
1144 * Use IDENTIFY command to resolve the server information in the
1145 GETKEY command instead of INFO command. Affected file
1146 lib/silcclient/command.c.
1148 * All command reply functions in the client library now calls
1149 the pending command reply callbacks even if an error has
1150 occurred. The server has done this a long time and now it was
1151 time to move the client library to this as well. Now all
1152 errors can be delivered back to the pending command reply
1153 callbacks if necessary. Affected files are
1154 lib/silcclient/command[_reply].[ch].
1156 * Change the nickname on disconnection back to the username
1157 because in reconnect the server will enforce it to it anyway.
1158 Affected file irssi/src/silc/core/silc-servers.c.
1160 * Fixed a config file parsing bug in the Irssi SILC client.
1161 Affected file irssi/src/silc/core/clientconfig.c.
1163 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * When printing the channel mode on JOIN, verify that the
1166 channel key and channel's HMAC are valid. Affected file
1167 irssi/src/silc/core/client_ops.c.
1169 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1172 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1173 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1175 * Removed channel key rekey task deleting from the function
1176 silc_server_save_channel_key. Affected file silcd/server.c.
1177 Added explicit timeout task context instead that is used to
1178 delete the task if we are registering a new task before the
1179 new task has elapsed.
1181 * When channel key rekey occurs the client library now saves
1182 the old channel key for a short period of time (10 seconds) and
1183 is able to use it in case some is still sending channel
1184 messages encrypted with the old key after the rekey. Affected
1185 file lib/silcclient/[idlist.h|client_channel.c].
1187 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * Added check to the silc_server_new_id_real to not accept
1190 new ID if it is the sender's own ID. Affected file is
1191 silcd/packet_receive.c.
1193 * Assure that we do not announce ourself or the one we've
1194 sending our announcements when we're router and are announcing
1195 servers to our primary router. Affected file silcd/server.c.
1197 * Fixed silc_server_command_identify_check_client to assemble
1198 correct WHOIS packet. It send corrupted WHOIS packet and
1199 caused problem with router to router connections. Affected
1200 file silcd/command.c.
1202 Fixed also silc_server_command_whois_check the same way
1203 as for the IDENTIFY command.
1205 * Added new SilcIDListStatus to the server in the SilcIDListData
1206 structure. The status now includes the current status of
1207 the entry (like registered, resolved etc.). Affected file
1208 silcd/idlist.[ch]. Defined a bunch of different status types
1209 as well. This replaced the old boolean registered field as well.
1211 Added resolve_cmd_ident field to the SilcClientEntry structure
1212 too so that if the entry is for example being resolved so
1213 another command may attach to the same pending command reply
1214 without requiring to resolve the same entry again. This concept
1215 should optimize the WHOIS and the IDENTIFY resolving under
1216 heavy load by taking away unnecessary resolving for entries
1217 that are being resolved already.
1219 Added support for adding multiple pending commands for one
1220 command idenfier. Affected file silcd/command[_reply].[ch].
1222 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1223 before deleting the data. Otherwise the hash table will have
1224 freed data in comparison functions. Affected file is
1225 silcd/command_reply.c.
1227 * Fixed silc_idlist_replace_client_id to add the new entry to
1228 the cache with NULL nickname. Otherwise there will be invalid
1229 memory as the nickname after the nickname is freed. Affected
1230 file silcd/packet_receive.c.
1232 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1233 saved into wrong slots because the previous number of entries
1234 was not taken into account. Affected file silcd/idlist.c.
1235 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1237 * If we are router and we receive JOIN notify to a channel that
1238 does not have any users then notified client is marked as the
1239 channel founder, as it is it. The affected file is
1240 silcd/packet_receive.c
1242 * Added to the extended hash table API's table_del_*ext functions
1243 the destructor as argument too, so that the caller can decide
1244 which destructor to use or whether to use destructor at all.
1245 Affected file lib/silcutil/silchashtable.[ch].
1247 * Fixed ID Cache purging. It actually deleted the entries from
1248 the hash table after the data was freed. The hash table ended
1249 up comparing freed memory. The affected file is
1250 lib/silccore/silcidcache.c.
1252 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1254 * Fixed Irssi SILC client's KILL command's HELP syntax.
1256 * The USERS command now resolves the detailed user information
1257 if the userinfo field is missing. Affected file is
1258 lib/silcclient/command_reply.c.
1260 * Do not print error in silc_file_read if the read file does
1261 not exist. Just silently return NULL. Affected file is
1262 lib/silcutil/silcutil.c.
1264 * Fixed the silc_log_output to not wine about NULL filename
1265 and to not create some bogus " " filename. Affected file is
1266 lib/silcutil/silclog.c.
1268 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Fixed various printing bugs on the user interface in the
1271 Irssi SILC Client. Minor changes that were forgotten from
1274 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Fixed the configure.in.pre and the compilation and distribution
1277 environment to support the new autoconf 2.52. That version is
1278 now required to compile the CVS trunk.
1280 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1283 to generally parse user@fqdn format strings. Affected file
1284 lib/silcutil/silcutil.c.
1286 * Added nickname_format and nickname_force_format fields to the
1287 SilcClientParams structure. The first one defines the format
1288 for the nicknames that the library will enforce if the receives
1289 multiple same nicknames. The second one is boolean value and
1290 can be used to force the library to always enforce the format
1291 to the nicknames regardles whether there are multiple nicknames
1292 or not. This configurable formatting was employed to flexibly
1293 support accessing multiple nicknames from the user interface.
1294 The userinterface can now set the nicknames to what ever format
1295 they prefer. Affected file lib/silcclient/silcapi.h.
1297 Added function silc_client_nickname_format to the file
1298 lib/silcclient/idlist.c. It performs the nickname formatting.
1300 Added new field `hostname´ to the SilcClientEntry context.
1301 It holds the hostname of the client. Affected file is
1302 lib/silcclient/idlist.h.
1304 * Irssi SILC Client sets the nicknames in nick@hostn format.
1305 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1306 irssi/src/silc/core/silc-core.c.
1308 The WHOIS printing now also shows both the real nickname and
1309 the formatted nickname so that user knows how to access the
1310 user if there are multiple same nicknames cached. Affected
1311 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1312 printing formatting too to take the hostname now as a separate
1313 argument. The Affected file is
1314 irssi/src/fe-common/silc/modules-formats.[ch].
1316 * Changed the silc_client_get_clients_local to accept the formatted
1317 nickname as argument. It accepts the real nickname too but the
1318 formatted nickname can be used to find the true entry from
1319 multiple entries. Affected file lib/silcclient/silcapi.h and
1320 lib/silcclient/idlist.c.
1322 * Added nickname_format_parse field to the SilcClientParams.
1323 It is a callback function provided by the application to parse
1324 the nickname out of the formatted nickname string. The library
1325 calls it to get the nickname from the formatted string. Since
1326 the application generally knows better the format of the nickname
1327 string it parses it instead of the library, even though library
1328 encodes the formatted string. If the callback function is not
1329 provided then the library will use the string as is. The
1330 affected file is lib/silcclient/silcapi.h.
1332 * All the nickname strings passed to the client library in
1333 commands are now expected to be formatted nickname strings.
1334 If the command does not support the formatted nickname string
1335 it will assume that the sent string is the actual nickname.
1336 Affected file lib/silcclient/command.c.
1338 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Added public key authentication support to OPER and SILCOPER
1341 commands in the client library. Affected file is
1342 lib/silcclient/command.c.
1344 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Changed the get_auth_methdod client operation to be asynchronous.
1347 It can be async if the application resolves the authentication
1348 method from the server during the negotiation. Added new
1349 SilcGetAuthMeth completion callback that the application will
1350 call after resolving the authentication method.
1352 Added function silc_client_request_authentication_method that
1353 the application can use to resolve the authentication method
1354 from the server. Added also SilcConnectionAuthRequest callback
1355 that the library will call after the server has replied. The
1356 application can call this function if it does not know the
1357 current authentication method.
1359 Affected files are lib/silcclient/client.c and
1360 lib/silcclient/silcapi.h.
1362 * The Irssi SILC client now automatically resolves the authentication
1363 method incase any configuration information is not present (and
1364 currently there never is). The affected file is
1365 irssi/src/silc/core/client_ops.c.
1367 * Fixed public key authentication from the client library.
1368 Affected file lib/silcclient/protocol.c. Changed also the
1369 protocol specification about the public key authentication in
1370 the connection authentication protocol. The actual data to be
1371 signed is now computed with a hash function before signing.
1373 * Fixed the public key authentication from the server as well.
1374 Affected file silcd/protocol.c.
1376 * Removed the mlock()'s from the memory allocation routines.
1377 Affected file lib/silcutil/silcmemory.c. The ./configure does
1378 not check anymore for the mlock(). Affected file is
1381 * Fixed USERS command in server to allow the execution of the
1382 command for private and secret channels if the client sending
1383 the command is on the channel. Affected file silcd/command.c.
1385 * Fixed silc_client_get_clients_local to return the clients
1386 count correctly. It could return wrong value. Affected file
1387 lib/silcclient/idlist.c.
1389 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1392 types. The assembler optimizations seemed not to like 64-bit
1393 data types. The assmebler optimizations thus are now enabled
1394 also for BSD systems as opposed to only enable them for Linux.
1396 * Do not check for threads at all on BSD systems. Affected
1397 file configure.in.pre.
1399 * Removed -n and -h options from the Irssi SILC Client since
1400 they are not used in silc.
1402 * Fixed the prime generation to assure that the first digit
1403 of the generated random number is not zero since our conversion
1404 routines does not like number strings that starts with zero
1405 digit. If zero digit is seen the random number is regenerated.
1406 This caused some corrupted RSA keys when the zero first digit
1407 was met. Affected file lib/silcmath/silcprimegen.c.
1409 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Fixed WIN32 configuration in the ./configure script.
1412 Fixed to include xti.h on environments that has it.
1413 Patches by Carsten Ilchmann and andrew.
1415 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Changed the silc_id_create_client_id to be collision
1418 resistant. It is now assured that there cannot be created
1419 two same client ID's. I suspect that some weird bugs in
1420 the server were actually caused by duplicate Client IDs.
1421 Affected file silcd/serverid.[ch]. A router receiving
1422 new ID now also assures and informs the sending server
1423 if the ID caused collision.
1425 * Changed the silc_id_create_channel_id to also assure that
1426 there are no collisions.
1428 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Statement about ignoring the Mutual Authentication flag when
1431 performing rekey with PFS was a bit misleading. It is ignored
1432 if it was set in the initial negotiation, it cannot be even
1433 set in the rekey. Fixed in the ke-auth draft. Started the
1434 new versions of the protocol drafts in the doc/.
1436 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Fixed a bug in silc_client_command_identify_save when saving
1439 new channel information. The channel name was no duplicated
1440 and caused crash on exit. Affected file is
1441 lib/silcclient/command_reply.c.
1443 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Fixed the getkey command handling in the server. Send just
1446 empty OK reply to the sender if the key could not be fetched
1447 (but everything else was ok, like the key just was not available).
1448 Changed the public key parameter to optional in the protocol
1449 specs so that empty OK reply can be sent. Affected file
1452 Added a message to Irssi SILC client to tell to user if the
1453 server did not return a public key.
1455 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Fixed a channel key regeneration bug. It registered new
1458 timeout tasks exponentially until all system resources were
1459 used. Affected file silcd/server.c.
1461 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Added the SILC Document generator to the scripts/silcdoc.
1464 It can be used to generate the Toolkit Reference Manual out
1465 of the source tree. Internally it will also use the RoboDoc
1466 generator now imported in util/robodoc.
1468 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Added couple of return's in rekey protocol if error orccurred
1471 during the protocol. The execution must be terminated.
1472 Affected file silcd/protocol.c. Also, terminate the protocol
1473 always with timeout.
1475 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * The client's Client ID was created initally from the wrong
1478 nickname (it could have been in format nick@host) in the
1479 silc_server_new_client. Affected file silcd/packet_receive.c
1481 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * Added some SILC_LOG_ERROR's to various error conditions
1484 if client could not be added to ID cache. Affected files
1485 silcd/packet_receive.c and silcd/server.c.
1487 * When client's sock->user_data is freed, NULL also the
1488 client->router and client->connection pointers. Added check
1489 for these pointers being NULL to various places around the
1490 code. Affected file silcd/server.c.
1492 * Added client->data.registered == TRUE checks to various
1493 places around the code to assure that unregistered client's
1494 are not handled when it is not allowed. Affected file
1497 * Added `bool registered' fields to all
1498 silc_idlist_[server|client]_get_* routines to indicate whether
1499 the fetched client needs to be registered or not. Affected
1500 file silcd/idlist.[ch].
1502 * Add your own entry as registered to the ID cache in the
1503 server. Affected file server.c.
1505 * Fixed a bug in silc_server_new_server. The SilcServer was
1506 set as the new server's context instead of SilcServerEntry.
1507 This naturally caused some weird bugs.
1509 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Do not delete the channel rekey task when adding it
1512 for in silc_server_create_channel_key.
1514 * Changed the silc_server_create_channel_key to return
1515 TRUE or FALSE to indicate the success of the channel key
1518 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Fixed MSVC++ project files and added missing files to
1521 Makefiles under win32/.
1523 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Do not add TCP_NODELAY flag if the operating system
1526 does not have it defined. Affected files are
1527 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1529 * Fixed buffer overflow from Irssi SILC Client. Affected
1530 file irssi/src/fe-common/core/themes.c.
1532 * Fixed double free in client library in the file
1533 lib/silcclient/client.c when disconnecting from server.
1535 * Applied double free patch from cras to Irssi SILC client.
1536 Affected files irssi/src/core/[modules/expandos].c
1538 * Fixed the disconnection handling to Irssi SILC Client.
1539 The application must call silc_client_close_connection
1540 in ops->connect client operation in case of failure of
1541 the connection. Affected file is
1542 irssi/src/silc/core/client_ops.c.
1544 * Do not set sock->protocol to NULL in the function
1545 silc_client_close_connection after executing the protocol's
1546 final callback since the sock might not be valid anymore.
1547 Affected file lib/silcclient/client.c.
1549 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Do not enable SILC_THREADS if the linking with libpthread
1552 did not happen. Affected file configure.in.pre.
1554 * Added notion to protocol specification that server must
1555 verify the sent authentication payload with CMODE when
1556 setting the channel founder key. Implemented it to the
1557 server. Affected file silcd/command.c.
1559 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Added _EXTRA_DIST SILC distribution variable to the
1562 distributions file. It is used to conditionally add extra
1563 files or directories to the specific distribution. Affected
1564 files ./prepare, Makefile.am.pre and distributions.
1566 Removed the `_' from the start of the distribution names.
1569 * Added README.WIN32 for instructions to compile the Toolkit
1572 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Fixed a double free in disconnection in the server. Affected
1575 file is silcd/server.c.
1577 * Fixed the lib/silcske/groups.c to work now also with GMP
1578 MP library. The string conversion did not work when using
1579 specific base and the base is indicated in the string as well.
1581 * Created win32/ directory which now includes MSVC++ specific
1582 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1583 It will appear only in the toolkit distribution
1585 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Changed the key material distribution function in case when
1588 the hash output is too short. The data is now concatenated
1589 a bit differently than it used to. Made the change to the
1590 SKE protocol specification.
1592 * Added better GMP detection to configure.in.pre. A patch
1595 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Fixed a minor bug in SKE that might cause some problem on
1598 some platforms. Affected file lib/silcske/silcske.c.
1600 * Added the cookie checking for initiator in the SKE. It checks
1601 that the responder returns the sent cookie unmodified. The
1602 affected file is lib/silcske/silcske.c. Added new SKE
1603 error type INVALID_COOKIE that can be sent during the
1604 negotiation. Fixed some memory leaks as well.
1606 * Added the "invalid cookie" error message to Irssi SILC client's
1609 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Added `task_max' field to the SilcClientParams to indicate
1612 the maximum tasks the scheduler can handle. If set to zero,
1613 default values are used. Affected file lib/silcclient/silcapi.h.
1615 * Fixed memory leaks in silc_client_close_connection. Affected
1616 file lib/silcclient/client.c.
1618 * Added silc_client_del_client_entry to client library to free
1619 all memory of given client entry. Affected file is
1620 lib/silcclient/idlist.[ch].
1622 * Added new functions silc_client_del_channel and
1623 silc_client_del_server to delete channel and server entries.
1624 Affected file lib/silcclient/[silcapi.h/idlist.c].
1626 * Removed silc_client_del_client_by_id from silcapi.h.
1628 * Fixed the INFO command to return the server's own info
1629 correctly when querying by Server ID. Affected file is
1632 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * Removed the non-blocking settings in WIN32 code in the
1635 silc_sock_[read/write] and added SleepEx instead. Affected
1636 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1637 of input data is now checked with FIONREAD and ioctlsocket.
1639 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Call silc_schedule_task_del_by_context in the
1642 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1643 Affected file lib/silccore/silcprotocol.c.
1645 * Call silc_protocol_cancel for active protocols in the
1646 silc_server_close_connection if the funtion
1647 silc_server_free_sock_user_data has not been called.
1648 Affected file silcd/server.c.
1650 * Generic tasks cannot be deleted using the del_by_fd
1651 task deleting function since generic tasks does not match
1652 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1654 * Added a notion to SILCOPER help file that the SILCOPER works
1655 only on router server, not on normal server.
1657 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Added for WIN32 support for the new scheduler as well.
1660 Affected file lib/silcutil/win32/silcwin32schedule.c.
1662 * Fixed the SHA1 implementation to work on various platforms.
1664 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1667 API. It is part of the scheduler now. Everything else is
1668 as previously but some functions has changed their names.
1669 Checkout the lib/silcutil/silcschedule.h for the interface.
1670 Updated all applications to use the new interface. Affected
1671 files are lib/silcutil/silcschedule.[ch].
1673 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1675 * Found a bug in the SKE implementation. The HASH value,
1676 specified by the protocol, was not computed correctly. The
1677 public key of the responder was not added to the computation
1678 even though it is mandatory. Affected file lib/silcske/silcske.c.
1679 This unfortunately causes incompatibilities with older
1680 clients and servers.
1682 * Added WIN32 specific network init and uninit functions:
1683 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1684 the Winsock2. Affected file lib/silcutil/silcnet.h and
1685 lib/silcutil/win32/silcwin32net.c.
1687 * Set the socket always to nonblocking mode on WIN32 after
1688 reading data or writing data. Affected file is
1689 lib/silcutil/win32/silcwin32sockconn.c.
1691 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Fixed various compilation problems under WIN32. Affected
1694 files lib/silcutil/win32/silcwin32thread.c and
1695 lib/silcutil/win32/silcwin32schedule.c.
1697 * Removed all _internal.h #includes from public header
1698 files. Internal headers must never be included from
1701 Removed also the lib/silcske/payload_internal.h file.
1703 * All include files that may be needed (public and some others
1704 included by the public headers) by application developers are
1705 now copied to the ./includes directory. It does not copy any
1706 internal headers. Affected file Makefile.defines.pre and all
1707 Makefile.am's under lib/ and subdirs.
1709 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Do not change the ~/.silc directory's permissions automatically.
1712 Affected file irssi/src/silc/core/clientutil.c.
1714 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Do not cancel the protocol in silc_server_close_connection
1717 it might cause recursion. Now cancelled in the function
1718 silc_server_free_sock_user_data. Affected file silcd/server.c.
1720 * Fixed the silc_server_remove_clients_by_server to regenerate
1721 the channel keys correctly finally. Added also new function
1722 silc_server_remove_clients_channels to actually do it.
1723 Affected file silcd/server.c.
1725 * Fixed the silc_server_new_channel to not crash by giving
1726 wrong router to the new channel. Affected file is
1727 silcd/packet_receive.c.
1729 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1732 which is given as argument to the silc_client_alloc now.
1733 It can be used to configure the client and set various parameters
1734 that affect the function of the client.
1736 * The USERS command in server did not check whether the channel
1737 is private or secret. Affected file silcd/command.c.
1739 * Added new argument to the USERS command in protocol specification.
1740 The USERS command now can take the channel name as argument
1741 as well. Added support for this in client and server and
1742 updated the protocol specs.
1744 * Completed the GETKEY command in client. It can be now used
1745 to fetch also servers public key not only some clients.
1746 Affected files lib/silcclient/command[_reply].c.
1748 * Added silc_client_get_server to return server entry by the
1749 server name. Affected files lib/silcclient/silcapi.h and
1752 * Redefined the IDENTIFY command in protocol specification to be
1753 more generic. It now can be used to query information about
1754 any entity in the SILC Network, including clients, servers and
1755 channels. The query may be based either the entity's name
1756 or the ID. Added support for this in both client and server.
1758 Affected files silcd/command.c and lib/silcclient/command.c
1759 and command_reply.c.
1761 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1762 the _from_client and _from_server functions. Affected file
1765 * Added silc_client_get_channel_by_id_resolve to the file
1766 lib/silcclient/silcapi.h to resolve channel information by
1767 its ID. Added also silc_client_get_channel_by_id that
1768 does not resolve it from the server.
1770 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1772 * Added SilcServerEntry context into the client library
1773 to represent one server. The INFO command now allocates
1774 these to save the resolved server info. For now on the
1775 client library will also keep information about servers,
1776 connected and resolved with INFO.
1778 The INFO command now allocates the SilcServerEntry context
1779 and saves the server info there. The COMMAND_REPLY in
1780 the INFO now returns the parameters to application in
1781 same order as defined in the protocol specification.
1783 The entries are cached in the client->server_cache.
1785 * The INFO command is now issued after received the Client ID
1786 from the server. Affected file lib/silcclient/client.c.
1788 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1789 to the application as the mode changer might be server.
1790 It is guaranteed that NULL is not returned anymore to the
1791 application. Affected file lib/silcclient/client_notify.c.
1793 The ID Type is now also passed to the application so that
1794 it can check whether the returned entry is SilcClientEntry
1797 Added new function silc_client_get_server_by_id to return
1798 the server entry by ID. Affected files are the
1799 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1801 * Do not create the channel in the Irssi SILC Client when issuing
1802 the JOIN command but when received the sucessful JOIN command
1803 reply. Otherwise the channel might get created even though we
1804 could not join it. The Affected file is
1805 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1807 * Fixed a channel joining bug in router. The router must also
1808 check the channel modes, invite and ban lists etc. when serving
1809 the JOIN command sent by normal server. Affected file is
1810 silcd/command.c. The router now resolves the client's
1811 information from the server who sent the JOIN command if it
1812 does not know it, and processes the JOIN command only after
1815 * Changed the SilcCommandCb to take new argument; void *context2.
1816 Affected file lib/silccore/silccommand.h
1818 The second argument in the command callbacks in the server now
1819 includes the SilcServerCommandReplyContext if the command was
1820 called as pending command callback from the command reply.
1821 Otherwise it is NULL. When called as pending the status of the
1822 command reply will be checked and if it was erronous the
1823 error will be sent to the original sender of the command.
1824 This way the client always receives the error messages even
1825 though the server was actually the one who received the error
1826 when it resent the command to router, for example. Affected
1827 files silcd/command[_reply].[ch].
1829 * Fixed sending WHOWAS command's error message to client if
1830 the requested client could not be found. It was missing.
1833 * Changed the CMODE and CUMODE commands reply arguments in the
1834 protocol specification. The Channel ID is now sent in both
1835 of the commands to identify the channel. Implemented this
1836 new feature to the client and server. Affected files
1837 lib/silcclient/command_reply.c and silcd/command.c.
1839 * Made better checks for invite and ban lists in the JOIN
1840 command in server. Affected file silcd/command.c.
1842 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * The server now performs the incoming host IP/DNS lookup
1845 using the silc_socket_host_lookup and thus does not block
1846 the server anymore. Affected file silcd/server.c.
1848 * Completed the multi-thread support for SILC Scheduler in
1849 the lib/silcutil/silcschedule.c.
1851 * Fixed the configure.in.pre to detect the pthread correctly
1854 * Fixed a deadlock in silc_task_queue_wakeup in the file
1855 lib/silcutil/silctask.c.
1857 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Added new function silc_schedule_wakeup that is used in
1860 multi-threaded environment to wakeup the main thread's
1861 schduler. It needs to be used when a thread adds a new task
1862 or removes a task from task queues. After waking up, the
1863 scheduler will detect the task queue changes. If threads
1864 support is not compiled in this function has no effect.
1865 Implemented the wakeup mechanism to both Unix and WIN32
1866 systems. Affected files are lib/silcutil/silcschedule.[ch],
1867 lib/silcutil/unix/silcunixschedule.c and the
1868 lib/silcutil/win32/silcwin32schedule.c.
1870 * Added new function silc_task_queue_wakeup to wakeup the
1871 scheduler by the specified task queue. Affected file
1872 lib/silcutil/silctask.[ch].
1874 * The silc_socket_host_lookup_start now wakes up the scheduler
1875 after adding the timeout task. Affected file is
1876 lib/silcutil/silcsockconn.c.
1878 * The silc_socket_host_lookup is synchronous now if the threads
1879 support is not compiled in. However, the callback is still
1880 called asyncronously through the scheduler, anyway. Affected
1881 file lib/silcutil/silcsockconn.c.
1883 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Added new function silc_socket_host_lookup to perform
1886 asynchronous IP and FQDN lookups for the socket connection.
1887 Affected files lib/silcutil/silcsockconn.[ch].
1889 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1892 that may or may not compile the mutex support in.
1894 Changed the silc_mutex_alloc interface. It allocates the
1895 mutex now to the sent pointer and returns TRUE or FALSE.
1897 Affected file lib/silcutil/silcmutex.h.
1899 * Wrote the SILC Task Queue interface to support multi-threads.
1900 Affected file lib/silcutil/silctask.[ch].
1902 * Wrote the SILC Scheduler to support multi-threads. Affected
1903 file lib/silcutil/silcschedule.c.
1905 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1908 in lib/silcutil/win32/.
1910 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Defined SILC Mutex API and SILC Thread API and implemented
1913 them for Unix. Affected files are
1914 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1915 lib/silcutil/unix/silcunixmutex.c and
1916 lib/silcutil/unix/silcunixthread.c.
1918 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Fixed the silc_server_remove_clients_by_server's channel
1921 key re-generation. The hash table handling was incorrect
1922 and would not work with many channels. Affected file is
1925 * Fixed some memory leaks around the server code.
1927 * Rewrote the silc_server_get_users_on_channel to support IPv6
1928 based Client ID's. Affected file silcd/server.c.
1930 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1931 specification. However, a separate document must be written
1932 to define the detailed signing procedure and the payload
1933 associated with the flag. Defined the flag to the
1934 lib/silccore/silcchannel.h as well.
1936 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Changed the dynamic tables to static size tables in the
1939 lib/silccrypt/silchmac.c.
1941 * Removed GCC dependencies from the code. A patch by cras.
1943 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Do not show the error "Error receiving packet bla bla"
1946 in server if it really was not an error (-2 means that reading
1947 is pending). Affected file silcd/server.c.
1949 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1951 * Fixed a possible crash in silc_server_remove_clients_by_server
1952 in silcd/server.c. Fixed there also some memory leaks.
1954 * Fixed the silc_idlist_replace_client_id. It could replace
1955 wrong key in the hash table. Affected file silcd/idlist.c.
1957 * Do not check whether there are global users on the channel
1958 if the channel->global_users is FALSE. Affected functions
1959 silc_server_remove_from_one_channel and
1960 silc_server_remove_from_channels in silcd/server.c. Also,
1961 do not check if the removed client is local as we can be
1962 sure that global client was not removed from the channel
1963 and checking for global users is not needed.
1965 * The silc_server_remove_clients_by_server now re-generates
1966 the channel keys correctly for those channels that had
1967 clients removed from them. Affected file silcd/server.c.
1969 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Found the reason of random crashes in the server. We weren't
1972 ignoring the SIGPIPE signal (which can be sent in write())
1973 and it crashed the server. Affected file silcd/silcd.c.
1975 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Assure that sock->user_data is not NULL in the function
1978 silc_server_packet_send in silcd/packet_send.c.
1980 * Disconnect the remote connection if it could not be added
1981 to any ID lists in the server. The affected file is
1984 * Check in silc_server_packet_send[_real/dest] that the
1985 socket is not disconnecting and ignore the data if it is.
1986 Affected file silcd/packet_send.c.
1988 * Define inline to __inline on native WIN32 compilation.
1989 Affected file includes/silcwin32.h.
1991 * Added some explicit type casts for inline code since MSVC
1992 require them. Affected files lib/silcutil/silcbuffer.h,
1993 lib/trq/silcdlist.h and lib/trq/silclist.h.
1995 * Print warning in log files from now on if the packet
1996 decryption fails. Affected file silcd/server.c.
1998 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Changed the `say' client operation's interface to accept
2001 new `type' argument to indicate the type of the message sent
2002 by the library. The application may filter the library's
2003 messages according the type. The affected file is the
2004 lib/silcclient/silcapi.h.
2006 * Added two new functions to lib/silcclient/silcapi.h:
2007 silc_client_del_client and silc_client_del_client_by_id.
2008 Affected file lib/silcclient/idlist.c.
2010 * Moved the clientincludes.h from includes/ to silc/ and
2011 serverincludes.h from includes/ to silcd/.
2013 * The modes for the CMODE and CUMODE are now passed as
2014 uint32 for application with COMMAND_REPLY. The affected
2015 file is lib/silcclient/command_reply.c.
2017 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * /WHOIS without arguments shows client's own information.
2020 Affected file lib/silcclient/command.c.
2022 * Changed PING to not accept any arguments. The specs
2023 says that client can ping only the connected server so
2024 requiring an argument is not needed. Affected file is
2025 lib/silcclient/command.c.
2027 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2029 * Fixed a fatal bug in private message sending and reception
2030 encryption and decryption when using private message keys.
2031 The implementation was incorrect and did not follow the
2032 specification. It causd that some of the message were
2033 lost since it did not use the sending and receiving keys
2034 as the protocol suggests. This has been fixed and will cause
2035 incompatibilities with older clients when sending private
2036 message encrypted with private message keys. Affected files
2037 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2038 and various other in Irssi SILC Client.
2040 Added `responder' boolean argument to the functions
2041 silc_client_add_private_message_key[_ske] to indicate when
2042 the key is added as responder or initiator of the key
2045 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Removed the silc_ske_check_version function and created
2048 a SilcSKECheckVersion callback. Added also a function
2049 silc_ske_set_callbacks that is now used to set all SKE
2050 callbacks. The callback functions are not given to
2051 the SKE functions anymore, but this function is used to
2054 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2056 * Added `silc_version' argument to the silc_client_alloc
2057 to define the version of the application for the library.
2058 The library will use the version string to compare it
2059 against the remote host's (usually a server) version
2060 string. Affected file lib/silcclient/silcapi.h
2062 * Added the KE protocol context to Key Agreement context
2063 in client library so that we can abort the SKE if it
2064 is in process when we get timeout. Affected file is
2065 lib/silcclient/client_keyagr.c.
2067 * Do not resolve the client ID forever if it returns in the
2068 first time that such client does not exist. This was done
2069 for example with private message. Affected file is
2070 lib/silcclient/client_prvmsg.c.
2072 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2074 * Do not add regex.h for WIN32. The affected file
2075 includes/silcincludes.h.
2077 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2078 not work yet 100%. It generates the DLL's automatically
2079 when compiling with --with-win32 under cygwin.
2081 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * lib/contrib/regex.c is not compiled on WIN32.
2085 * Added silc_net_get_socket_opt function to the
2086 lib/silcutil/silcnet.h.
2088 * Added includes/silcwin32.h for WIN32 specific includes
2091 * Do not use ptime structure or any of the posix process
2092 functions on WIN32 in lib/silccrypt/silrng.c.
2094 * Added silc_gettimeofday to provide generic function
2095 for struct timeval on all platforms. Added the function
2096 to lib/silcutil/silcutil.h.
2098 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2101 library as they clearly belong there. As a plus side we
2102 can make the actual socket connection routines platform
2105 Added also new generic function silc_socket_read and
2106 silc_socket_write (that used to be silc_packet_[read/write].
2107 The implementation of these are platform specific.
2109 * Added WIN32 specific routines of silc_socket_[read/write]
2110 to lib/silcutil/win32/silcwin32sockconn.c.
2112 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Added preliminary support for native WIN32 compilation under
2115 cygwin (using the -mno-cygwin option for GCC) to the
2116 ./configure.in.pre. The --with-win32 now prepares the
2117 compilation for native WIN32.
2119 * Rewrote the SILC Scheduler interface in the file
2120 lib/silcutil/silcschedule.h. The scheduler is now context
2121 based and does not have anymore any global static scheduler.
2122 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2123 and created lib/silcutil/win32 directory for WIN32 based
2126 * Added Unix specific network routines to the
2127 lib/silcutil/unix/silcunixnet.c and the old
2128 lib/silcutil/silcnet.c includes now only generic routines.
2130 Added WIN32 specific network routines to the
2131 lib/silcutil/win32/silcwin32net.c.
2133 * Added Unix specific utility functions from the
2134 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2136 * Added WIN32 SILC Scheduler to the file
2137 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2140 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Do not handle JOIN notify in the server if the target client
2143 is not registered (idata->registered == FALSE). The affected
2144 file is silcd/packet_receive.c.
2146 * Update the nickrec->founder in event_cumode in the Irssi SILC
2147 client. Affected file irssi/src/silc/core/silc-channels.c.
2149 * Fixed the CUMODE_CHANGE notify handling in the server when
2150 server and router are announcing their clients on channels.
2151 Now the mode changes are saved and notified correctly. The
2152 affected file is /silcd/packet_receive.c.
2154 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2155 They really did not replace the cache entry in the ID Cache.
2156 Now they do that. Affected file silcd/idlist.c.
2158 * Fixed the KICK notify handling in the Irssi SILC client to
2159 update the channel records so that the kicked client does not
2160 appear to be on the channel. The affected file is
2161 irssi/src/silc/core/silc-channels.c.
2163 * Always update the conn->current_channel when executing command
2164 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2166 * Fixed the KILL notify handling in Irssi SILC client to remove
2167 the killed client on all channels.
2169 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Fixed the silc_parse_command_line to remove extra spaces
2172 from the start and end of the arguments. Affected file is
2173 lib/silcutil/silcutil.c.
2175 * Cancel and free any active protocol in the function
2176 silc_server_close_connection. Affected file silcd/server.c.
2178 * Cancel and free any active protocol in the function
2179 silc_client_close_connction. Affected file is
2180 lib/silcclient/client.c.
2182 * Do not execute the KILL command for clients that are in
2183 history (ie. they are not in the network). Affected file is
2186 * Fixed KILL notify handling, client does not crash anymore.
2187 Affected file irssi/src/silc/core/silc-channels.c.
2189 * Reduced the default packet buffer size from 2048 to 1024 in
2190 lib/silccore/silcpacket.c.
2192 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2193 counter to the SKE context that is incresed when the SKE library
2194 performs async operation outside the library. If the outside
2195 process frees the SKE context and FREED status will be set
2196 and the library will detect after the sync operation that the
2197 libary is freed. The affected files are
2198 lib/silcske/silcske[_status].[ch].
2200 * Resolve the client entry information in the function
2201 silc_client_channel_message to assure that NULL pointer is not
2202 passed as client entry to the application. */
2204 * Fixed the task timeout calculation to assure that there is
2205 never negative timeouts. The affected file is
2206 lib/silcutil/silcschedule.c.
2208 * Fixed the channel user mode notification sending in server.
2209 It was sent point-to-point to the router (or to server by router)
2210 but it needs to be destined to a channel. The routines now
2211 supports sending the channel user mode notifys to the channels
2212 when announcing clients and channels. Affected files are
2213 silcd/server.c and silcd/packet_receive.c.
2215 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2216 It did not actually replace the old channel entry in the cache.
2217 Affected file lib/silcclient/client_notify.c.
2219 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Fixed a possible crash in silc_packet_send_prepare. It now
2222 assures always that there is enough space in the buffer and
2223 at the tail area of the buffer (for MAC).
2225 Fixed the inbound buffer reallocation in silc_packet_read.
2226 It was old code and did not handle the reallocation correctly.
2229 The affected file is lib/silccore/silcpacket.c.
2231 * Fixed buffer overflow in silc_parse_nickname in the file
2232 lib/silcutil/silcutil.c.
2234 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * make install generates new server keys only if there is not
2239 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2242 Added check that if the NOREPLY is set then we will not send
2243 the away message. This avoids infinite loop of away messages
2244 if both clients are away. The affected file is
2245 lib/silcclient/client_prvmsg.c.
2247 * Fixed client crash if /NICK was given without arguments.
2248 Affected file lib/silcclient/command.c.
2250 * Server does not send the invite list in INVITE command back
2251 to the client if the list was not altered. Added this notion
2252 to the protocol spec as well. Affected file silcd/command.c.
2254 Fixed possible crash in INVITE command by checking the
2255 value of silc_server_get_client_route command.
2257 * Fixed the INVITE notify type handling. The arguments are now
2258 taken in correct order and client does not crash. The affected
2259 file is irssi/src/silc/core/silc-channels.c.
2261 Removed the "Inviting xxx to channel" message from the
2262 client library away and let the application handle it.
2263 Affected file lib/silcclient/command.c. Added that message
2264 to Irssi SILC client's message formats.
2266 * Fixed CMODE command crash in client. It now checks the
2267 amount of arguments correctly and does not crash. The affected
2268 file is lib/silcclient/command.c.
2270 * Do not create new channel automatically in silc_channels_join
2271 but check whether the channel by that name already exists.
2272 Affected file irssi/silc/core/silc-channels.c.
2274 * Do not send the SERVER_SIGNOFF to router if the disconnected
2275 entity was the router. Affected file silcd/server.c.
2277 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2278 SILC client as it was missing from there.
2280 Added the handling of the KICK notify to the Irssi SILC client
2281 as it was missing. Added "you have been kicked" message to
2282 Irssi SILC client's message modules formats.
2284 Added the handing of the KILL notify to the Irssi SILC client
2285 as it was missing. Added the kill message module formats
2288 The affected file is irssi/src/silc/core/silc-channels.c.
2290 * The router did not save the channel mode the server announced.
2291 Affected file silcd/packet_receive.c.
2293 * Fixed a possible crash in INFO command in server. If the
2294 server did not provide the server info it crashed. Affected
2295 file silcd/command.c.
2297 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Fixed the GETKEY command in the server to check also the
2300 global list. Otherwise the GETKEY would not work correctly
2301 in normal SILC server. Affected file silcd/command.c.
2303 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Fixed GETKEY crash, it crashed if the command did not succseed.
2307 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2310 is now real and not just an macro interface to GMP.
2312 Removed the entire GMP from the source tree and imported new
2313 NSS MPI library instead. Reason for removing GMP is that it is
2314 extremely large and compiles extremely slow. The NSS MPI
2315 is only a few files and compiles in less than 10 seconds.
2316 The speed is also about the same as GMP. The MPI is imported
2317 to lib/silcmath/mpi.
2319 If the system has GMP installed we will still use the GMP.
2320 If it is not then the NSS MPI will be compiled.
2322 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Merged a long nickname (127 characters long) crash bugfix from
2325 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2327 * Merged a freed memory reference bugfix from Irssi CVS tree.
2328 Affected file irssi/src/core/commands.c.
2330 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Added the server's public key sving and verification to the
2333 server when performing the SKE. This was missing and the
2334 remote server's (or router's) public key was accepted without
2335 checking whether we have it previously or trust it at all.
2336 Affected file silcd/protocol.c.
2338 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Check in the silc_server_timeout_remote if protocol is active
2341 and make sure that the protocol's final callback is called so
2342 that all memory if freed. Affected file silcd/server.c.
2344 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2346 * silc_server_whois_send_reply crashed the server if the nickname
2347 was 127 characters long. Affected file silcd/command.c.
2349 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2351 * Added sanity check to the silc_server_new_client. If the hostname
2352 is provided inside username then check that the provided hostname
2353 really is the same as the resolved one. If the hostname was not
2354 resolved then check it from the public key. Affected file is
2355 silcd/packet_receive.c.
2357 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2358 if the server disconnected us and the connection is not valid
2359 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2361 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2362 the library to the lib/silcutil/silcutil.[ch].
2364 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Close log file after open. Affected file
2367 lib/silcutil/silclog.c.
2369 * Check whether sock == NULL in silc_client_send_packet and return
2370 if it is. Affected file lib/silcclient/silcclient.c.
2372 * Check rec->entry == NULL in the Irssi SILC Client before
2373 sending the channel message. Affecte file is
2374 irssi/src/silc/core/silc-servers.c.
2376 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Merged a splitted window bugfix from Irssi CVS tree. The
2379 affected file is irssi/src/fe-text/textbuffer-view.c.
2381 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2382 It did not print nickname.
2384 * Improved the distributions system a bit.
2386 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2389 irssi/src/fe-text/gui-window.c.
2391 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2392 to in-active server. The affected file is
2393 irssi/src/silc/core/client_ops.c.
2395 * Resolve the client in USERS command reply if the entry does
2396 not have username resolved. The affected file is
2397 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2398 command to WHOIS command to really resolve stuff. The USERS
2399 is not used any more in any critical section so WHOIS can
2400 be used even though it might be slower than IDENTIFY.
2402 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2405 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Changed the protocol API a bit more consistent in the
2408 lib/silccore/silcprotocol.[ch].
2410 * Changed the following headers to ROBODoc format:
2412 lib/silccore/silcpayload.h
2413 lib/silccore/silcprotocol.h
2414 lib/silccore/silcsockconn.h
2416 All core library headers are now formatted.
2418 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * Fixed a bug in Irssi SILC client; do not show that you are
2421 server/router operator if you really are not. Affected file is
2422 irssi/src/silc/core/client_ops.c.
2424 * Renamed silc_command_free_payload to silc_command_payload_free.
2425 Affected file lib/silccore/silccommand.h
2427 * Added silcmath.h to include the prototoypes of various routines
2428 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2431 * Changed the following headers to ROBODoc format:
2433 lib/silccore/silcchannel.h
2434 lib/silccore/silccommand.h
2435 lib/silccore/silcid.h
2436 lib/silccore/silcidcache.h
2437 lib/silccore/silcmode.h
2438 lib/silccore/silcnotify.h
2439 lib/silccore/silcpacket.h
2440 lib/silcmath/silcmath.h
2442 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Added checking to the server code not to start the server if
2445 ciphers and stuff are not configured properly. Affected files
2446 silcd/serverconfig.[h] and silcd/server.c.
2448 * Changed the layout of the header files of the public interfaces
2449 in the SILC libraries. The new layout supports ROBODoc
2450 documentation tool (and some others) so that it is easy to create
2451 a library reference manual. All the other headers and source
2452 code must still follow the CodingStyle document. Also source
2453 code must not include these ROBODoc stuffs, only the headers.
2454 Furthermore, all public interface headers must now be named
2455 by using `silc' prefix, example: silcapi.h, silccipher.h.
2456 Some files were renamed due to this. All the other headers
2457 must not be used as public interfaces. I will update the
2458 CodingStyle document later. Changed following headers, so far:
2460 lib/silcclient/silcapi.h
2461 lib/silccore/silcauth.h
2462 lib/silccore/silcprivate.h
2463 lib/silccrypt/silcdh.h
2465 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Removed silc_client_packet_send_flush from the client library
2470 as it is not needed. Affected file lib/silcclient/client.[ch].
2472 * Added printing of message of unresolved authentication method
2473 to the Irssi SILC client. Added it to the module formats.
2474 Removed the same message from the client library.
2476 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Added new distribution feature, DISTLABEL. Every distribution
2479 can define own preprocessor label that can be used in the
2480 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2481 file distributions, acconfig.h.pre and prepare.
2483 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Added Makefile.defines_int to include the actual definitions
2486 for Makefile.defines.in. Tested the new distribution system,
2487 created distributions and tested installation.
2489 * Added AWAY message printing to the Irssi SILC client. Added
2490 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2492 * Added SCONNECT command to call the SILC's CONNECT command.
2493 Cannot use CONNECT directly since Irssi uses that internally.
2494 Affected file irssi/src/silc/core/silc-servers.c.
2496 Added ACTION local command. It is same as ME command but takes
2497 the channel as mandatory argument.
2499 Rewrote some of the Irssi's help files to suite for SILC
2502 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Added Makefile.defines[.in] that should for now on be included
2505 in all Makefile.am file in the source tree. That file includes
2506 all common compilation definitions for SILC source tree.
2508 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Minor changes to the ./prepare script to change the package
2511 name according the distribution name to the configure.in.
2513 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Created new distribution system. Added file `distributions'
2516 that defines all the distributions that can be created out of
2517 the SILC source tree. The ./prepare script now reads that
2518 file to determine how to prepare the distributions. The
2519 first argument to the ./prepare is the name of the distribution
2520 and second is the version of the distribution. If given
2521 without arguments it creates the default (toolkit) distribution
2522 with the default version (defined in ./prepare).
2524 All Makefile.am files that are subject to the distributions
2525 are now named as Makefile.am.pre. These are ./Makefile.am
2526 and lib/Makefile.am. Others may be changed later.
2528 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2530 * Added invite list, ban list, some key management and connection
2531 error message printing to module formats in the Irssi SILC client.
2533 * Added new silc_client_set_away_message to set the away message
2534 that is back to the person who sent private message. The
2535 affected file lib/silcclient/silcapi.h and the
2536 lib/silcclient/client_prvmsg.c.
2538 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2540 * Fixed the private message sending in the Irssi SILC client,
2541 added local command KEY to the Irssi SILC client.
2543 Added key management and key agreement message formats to the
2544 irssi/src/fe-common/silc/module-formats.[ch].
2546 Added USERS (alias WHO) printing, server/router operator
2547 indication and LIST command printing to the module formats.
2549 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Fixed channel joining notify handling, cumode notify handling
2552 from Irssi SILC client.
2554 * Added SILC specific module-formats to the Irssi SILC client so
2555 that SILC specific message hilighting, colors etc is possible.
2556 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2558 Added channel mode, channel user mode, actions, notices,
2559 whois and whowas printing to the the module-formats.c.
2561 * Fixed a bug in channel deletion in the server. The channel
2562 is not left to the cache even if the channel founder auth mode
2563 is set when there are no users anymore on the channel. Affected
2564 file silcd/server.c.
2566 * The silc_net_localhost now resolves the entire hostname including
2567 the domain name. Affected file lib/silcutil/silcnet.c.
2569 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * Changed the ask_passphrase client operation to be ascynchronous.
2572 It has now a completion callback and a context that the
2573 application must call after it has got the passphrase from
2574 the user. Affected files lib/silcclient/silcapi.h,
2575 lib/silcclient/protocol.c, lib/silcclient/command.c and
2578 Added SilcAskPassphrase callback that the application calls
2579 to deliver the passphrase to the library.
2581 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2582 The public key verification and especially a certificate
2583 verification is asynchronous procedure.
2585 Added new SILC_SKE_STATUS_PENDING status to indicate the
2586 request is pending and a callback will be called to finalize
2589 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2590 indicate that remote end did not send its public key (or
2591 certificate), even though we require it. Added check for this
2592 condition in the SKE. This was a security bug, now fixed.
2594 Defined new SilcSKEVerifyCbCompletion callback that is called
2595 when the verification process is completed.
2597 The affected files lib/silcske/silcske_status.h and
2598 lib/silcske/silcske.[ch].
2600 * Changed the verify_public_key client operation to be async
2601 as well. Defined SilcVerifyPublicKey callback that is used to
2602 indicate the success of the public key verification process.
2604 Changed the server and client to use the new async client
2607 * Changed the Irssi SILC client's internal scheduler to be called
2608 twice as many times as it used to be. As a result the client
2609 should be a bit faster now. Affected file is
2610 irssi/src/silc/core/silc-core.c.
2612 * Added support to Irssi SILC client of asynchronous public key
2613 verification and passphrase inquiry. Affected file is
2614 irssi/src/silc/core/silc-core.c.
2616 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Do not say "You have left channel %s" in client library.
2619 Moved it to the application. Affected files are
2620 lib/silcclient/command.c and silc/client_ops.c.
2622 * Fixed silc_client_get_clients. Command context was not
2623 duplicated and was freed memory in the callback. Affected
2624 file lib/silcclient/idlist.c.
2626 * Do not say "you are now talking..." on JOIN command in the
2627 client library. The appliation must handle it.
2629 * Do not say ".. changed topic to" in command reply in the
2630 client libary. The application must handle it.
2632 * Fixed TOPIC command sending in the client library.
2634 * Fixed a memory leak in silc_client_command_free in the file
2635 lib/silcclient/command.c.
2637 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Imported a modified version of Irssi client to the source tree.
2640 The Irssi will be used to create a new client called
2641 Irssi SILC. Imported to irssi/.
2643 Added silc_core_init_finish function to the Irssi. Affected
2644 file irssi/configure.in.
2646 A lot changes in the Makefile.ams around the irssi tree.
2648 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Do not rehash if the new size is same as the old size of the
2651 hash table, in the silc_hash_table_rehash*. The affected file
2652 lib/silcutil/silchashtable.c.
2654 * Replaced hash_table_del_by_context calls from the server
2655 (when channel->user_list and client->channels) to the
2656 hash_table_del as it is sufficient and faster.
2658 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Added silc_hash_table_list, silc_hash_table_get and the
2661 SilcHashTableList structure to provide an alternative way to
2662 traverse the hash table. The affected files are
2663 lib/silcutil/silchashtable.[ch].
2665 * Changed the server's idlist routines to use the hash table
2666 routines to optimize the code.
2668 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2670 * Replaced the client entry's `channel' list and channel entry's
2671 `user_list' list to hash tables for optimized lookup. Changed
2672 the code to use the hash table interface around the code.
2673 Affected file lib/silcd/idlist.[ch].
2675 * Added `auto_rehash' boolean argument to the function
2676 silc_hash_table_alloc to indicate whether the hash table should
2677 auto-rehash when it thinks is appropriate time. It will
2678 increase the hash table size if the there is twice as much
2679 entries in the table than the size of the table, and will
2680 decrease the size if there are twice as less entries than
2681 the size of the table.
2683 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2687 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2689 * silc_idcache_purge_by_context deletes the entry now by context
2690 as it is supposed to do. Affected file lib/silccore/idcache.c.
2692 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2693 client is not anymore valid (WHOWAS givens the info) and not
2694 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2696 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2698 * Removed the `data' and `data_len' arguments from the ID Cache
2699 interfaces and added `name' argument. ID Cache does not handle
2700 anymore the binary data only a names associated with given ID.
2702 * When hashing a Client ID with silc_hash_id the entire ID is
2703 not hashed anymore, instead only the hash of the Client ID is
2704 hashed. This way we can access the Client ID from the cache
2705 with Client ID but with the hash of the ID (which is a hash of
2706 the nickname) as well without any difference in performance.
2708 Added also silc_idcache_find_by_id_one_ext to do one on one
2709 searching when we have the actual ID. Added also function
2710 silc_hash_client_id_compare. The affected files are
2711 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2713 * When hashing the name associated with a ID it is always done
2714 in lowercase. This way we can access the cache without worrying
2715 about case-sensitivity, even though, for example nicknames are
2718 * Fixed a bug in server with channel message sending. It put
2719 wrong ID type as destination ID. The affected file
2720 silcd/packet_send.c.
2722 * silc_idcache_del_by_context now deletes from all hash tables
2723 by context. Affected file lib/silccore/idcache.c.
2725 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Changed the client library to use the new ID Cache interface.
2728 Changes around the source tree.
2730 * Added silc_hash_table_rehash_ext to rehash with specific
2731 hash function. Affected file lib/silcutil/silchashtable.[ch].
2733 * Added silc_hash_string_compare to compare two strings in the
2734 hash table. Affected file lib/silcutil/silcutil.[ch].
2736 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Added new function silc_idcache_del_by_context into the
2739 lib/silccore/idcache.[ch].
2741 * Changed the server's ID list routines to use the new ID Cache
2742 interface. Changes around the source tree.
2744 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * Added silc_hash_table_del[_by_context]_ext functions in to the
2747 lib/silcutil/silchashtable.[ch].
2749 Removed silc_hash_table_find_all* routines and added new
2750 silc_hash_table_find_foreach to replace them.
2752 Added silc_hash_table_replace_ext function as extended
2753 replacing function. Separated the simple hash table interface
2754 from the extended hash table interface in the file
2755 lib/silcutil/silchashtable.h.
2757 * Fixed minor bugs and changed it to use some of the new
2758 hash table functions in lib/silccore/idcache.c
2760 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * Added new function silc_hash_table_find_all to return all keys
2763 in the hash table by the specified key. As the hash table is
2764 collision resistant it also makes it possible to have several
2765 duplicate keys in the hash table. This function may be used to
2766 find all of the keys from the hash.
2768 Added user_context arguments to the SilcHashFunction,
2769 SilcHashCompare and SilcHashDestructor to deliver user specified
2772 Added new fuctions silc_hash_table_find[_all]_ext to do
2773 extended lookup with specified hash and compare functions and
2774 specified user contexts.
2776 Added new function silc_hash_table_add_ext to add the key
2777 with specified hash function and user context.
2779 Added new function silc_hash_table_foreach to traverse all
2780 entrys in the hash table. Added SilcHashForeach callback
2783 Added new function silc_hash_table_del_by_context to delete
2784 the entry only if the context associated with the key matches.
2786 Affected files are lib/silcutil/silchashtable.[ch].
2788 * Removed silc_hash_[server/client/channel]_id and added just
2789 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2790 silc_hash_id_compare to compare two ID's using as the hash table
2791 comparison function. Added also silc_hash_data to hash
2792 binary data and silc_hash_data_compare to compare it.
2794 * Removed silc_idlist_find_client_by_hash as it is not needed
2795 anymore. Affected file silcd/idlist.[ch].
2797 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2798 to use internally the SilcHashTable. The new ID Cache is a lot
2799 faster than the old one. Some of the ID Cache interface was also
2800 rewritten and obsolete and stupid functions were removed.
2802 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Added entry_count field to the SilcHashTable to keep the number
2805 of the entries in the table. Implemented the function
2806 silc_hash_table_rehash. Added new function
2807 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2809 Fixed a minor bug in silc_hash_table_free.
2811 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2812 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2813 into the lib/silcutil/silcutil.[ch].
2815 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Implemented a collision resistant hash table into the
2818 lib/silcutil/silchashtable[ch]. See the header and the source
2819 for the SilcHashTable API.
2821 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Merged dotconf version 1.0.2 into lib/dotconf.
2825 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2827 * Do not compile anything in lib/silcsim/* if the SIM support
2828 is not enabled. The tree should now compile without problems
2831 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Compiled the SILC under cygwin. Compiled and tested briefly
2834 without problems. More tests needed. The SIMs didn't compile
2837 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2839 * Fixed possible crash in silc_get_username in the
2840 lib/silcutil/silcutil.c.
2842 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Fixed a va_arg in silc/client_ops.c.
2846 * Oops, RC5 routines were named AES and caused some problems
2847 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2849 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Added new SilcIDIP structure into the lib/silccore/id.h and
2852 replaced the old `ip' fields from all SILC ID's to that type.
2853 This is a step towards IPv6 support.
2855 The silc_id_get_len takes now the ID as an extra argument.
2856 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2857 both IPv4 and IPv6 based ID's.
2859 The affected files are lib/silccore/id.[ch] and other files
2860 around the tree using these routines.
2862 * Removed the ID length arguments in server from various
2863 silc_server_send_notify_* routines -> they are not needed
2866 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Fixed memory leak in silc_encode_pem_file in the file
2869 lib/silcutil/silcutil.c.
2871 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Check minor version as well in the SKE. Affected files are
2874 silcd/protocol.c and lib/silcclient/protocol.c.
2876 * Added --identifier option to the server so that an identifier
2877 can be when creating the public key for the server. Affected
2878 file is silcd/silcd.c.
2880 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2881 lib/silccrypt/silcpkcs.c.
2883 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * Register default ciphers and stuff when using -C option with
2886 the server. Affected file sildc/silcd.c.
2888 * Put back the servers public key filename format, it is better
2889 than the new one. For now, the client keys are saved with the
2890 new filename format. The affected file silc/client_ops.c.
2892 * Implemented the Cipher API for the rest of the ciphers that
2893 did not implement it or implemented it the wrong way.
2895 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2897 * Register default ciphers and stuff when using the -S option
2898 in the client. Affected file silc/silc.c. Same also when
2899 creating new key pair with -C option.
2901 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Fixed the silc_verify_public_key client operation function to
2904 save the public keys differently. The fingerprint is now
2905 used as filename and not the hostname. This way also the
2906 client keys are saved uniquely and not with hostnames. The
2907 affected file is silc/client_ops.c.
2909 * Trimmed the silc_hash_fingerprint function to remove extra
2910 whitespaces from the end of the fingerprint. The affected
2911 file is lib/silccrypt/silchash.c.
2915 * Added silc_cipher_register_default function to register all
2916 default ciphers. It can be used when configuration files
2917 does not exist and the application does not want any specific
2918 ciphers in any specific order.
2920 The SilcDList is now used as silc_cipher_list dynamically
2921 allocated cipher list. Removed the static list all together
2922 and now all ciphers must be allocated to the dynamic list.
2923 The silc_cipher_alloc routine was changed to check only the
2926 All silc_cipher_* routines that used to return int returns
2929 The affected files lib/silccrypt/silccrypt.[ch].
2931 * The same thing was done to silc_hash_* as for silc_cipher_*
2932 routines. Affected files lib/silccrypt/silchash.[ch].
2934 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2935 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2936 Added also silc_pkcs_[un]register[_default] functions.
2937 Removed the data_context from the PKCS API.
2939 * Added silc_hmac_register_default function to register default
2940 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2941 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2942 to unregister all hmacs at once.
2944 * Register the default ciphers, hash functions, PKCSs and HMACs
2945 if client's configuration file does not exist. The affected
2948 * The client did not load the hash functions from the SIM
2949 modules at all. Added support for this. Affected file is
2950 silc/clientconfig.c.
2952 * When decoding public key with silc_pkcs_public_key_decode, check
2953 the supported algorithm only if PKCS are registered. Affected
2954 file lib/silccrypt/silcpkcs.c. The same was done with the
2955 silc_pkcs_private_key_decode.
2957 * Fixed the SILC List routines to keep the list always in order.
2958 It used to change the list's order when traversing the list but
2959 not it preserves the order. Affected file lib/trq/silclist.h.
2961 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2963 * Added the client library to use the SilcSocketConnection's
2964 reference counter (by silc_socket_dup) to prevent the bug that
2965 the socket object may be freed underneath async operation.
2967 * The name resolv library checking fixes in the configure.in.pre.
2970 * Created new version of the protocol drafts for future
2971 development. The -03 drafts are the ones that will be changed
2972 in the trunk now and the -02 will remain as they are.
2974 * Send list of CUMODE notifys to the router when announcing
2975 the channel users to the router. Affected file silcd/server.c.
2976 If the router receiving channel founder CUMODE for a channel
2977 that already has channel founder it will send CUMODE notify
2978 to the sender to remove the channel founder rights from the
2979 announced client. Affected file silcd/packet_receive.c.
2981 * The CUMODE notify may now use Server ID as well as the entity
2982 who changes the mode. Updated protocool specs.
2984 * Updated INSTALL and README files.
2986 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * New web pages in the http://silc.pspt.fi. The pages was
2993 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Implemented the [DenyConnectin] config section in the server.
2996 Added silc_server_config_denied_conn to check whether incoming
2997 connection is denied. Affected file silcd/serverconfig.[ch].
2999 * Do not check the ports when checking the incoming configuration
3000 data if the port is 0, meaning any. Affected file is
3001 silcd/serverconfig.c.
3003 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Fixed buffer overflow in silc_string_compare in the file
3006 lib/silcutil/silcutil.c.
3008 * Fixed double free in silc_server_command_leave in the file
3011 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Fixed the version checking in the server. Affected file is
3016 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed the configuration data fetching when accepting new
3019 connections in the server. Affected file silcd/server.c.
3021 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Added `sender_entry' argument to the function
3024 silc_server_packet_relay_to_channel so that we can check
3025 whether some destination actually belongs to the same route
3026 the sender belongs (ie, we must not resend the packet to the
3027 sender). Affected file silcd/packet_send.[ch].
3029 * Added `servername' field to the SilcClientEntry in the server
3030 to hold the name of the server where client is from. Affected
3031 file is silcd/idlist.h.
3033 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Moved the channel message encrypting in the router betwen
3036 router connections from silc_server_channel_message to the
3037 silc_server_packet_relay_to_channel since we want to check
3038 whether we have anybody channel before encrypting anything.
3039 Affected files silcd/packet_[receive/send].c.
3041 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Fixed the [AdminConnection] server config section to support
3044 multiple entries. Affected file silcd/serverconfig.c.
3046 * Added support into the server to check the validity of the
3047 incoming connection before executing any KE or authentication
3050 * The connection configuration is now saved to the KE and
3051 connection auth protocol contexts and not fetched anymore in
3052 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3054 * The local hosts listenning address and port is also resolved
3055 now when starting the server. We want to have the socket object
3056 to include the real address and port for the listener. Added
3057 new function silc_net_check_local_by_sock into the files
3058 lib/silcutil/silcnet.[ch].
3060 * Fixed a broadcast bug in server -> do not broadcast if we
3063 * Fixed a routing bug. Do not route broadcast packets ever.
3064 Broadcast packets must be processed always and not routed since
3065 they may be destined to some other host than yourself and thus
3066 would get routed without no good reason. Affected file is
3069 * Added function silc_server_config_is_primary_route to check
3070 whether primary router connection has been configured (a router
3071 configuration that we are initiating). If there is not, we
3072 will assume that there is only two routers in the SILC network
3073 and we will use the incoming router connection as our primary
3074 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3076 * Changed the order of the broadcasting. Broadcast _after_ the
3077 packet has been processed not before. Affected file is
3080 * Fixed a [ClientConnection] parsing bug. The port was never
3081 parsed correctly thus resulting to port 0. Affected file
3082 silcd/serverconfig.c.
3084 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3085 argument and did not set the broadcast packet flag. Affected
3086 file silcd/packet_send.c. Fixed same bug in the function
3087 silc_server_send_notify as well.
3089 * If we receive NEW_ID packet for our own ID in the server, ignore
3092 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Removed the nickname from the Private Message Payload.
3097 Updated the code and the protocol specs.
3099 * Updated protocol specs for submitting to the IETF.
3101 * Tweaked the Random Number Generator a bit. Affected file
3102 lib/silccrypt/silcrng.c. Exported a new function
3103 silc_rng_[global]_add_noise which can be used to add more
3106 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Do not parse packets with different timeout when protocol
3109 is active -> may cause problem with rekey. Affected file
3112 * When server receives signoff notify it must not create
3113 new channel key if the client is on any channels since the
3114 sender of the signoff notify will create it.
3116 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Added printing of error messages during SKE protocol from the
3119 failure packet sent by server during SKE. Affected file
3122 * Removed the client's failure_callback handling with timeout
3123 and handle it immediately when received.
3125 * The SKE library returned wrong type in SUCCESS and FAILURE
3126 packets. They must be 32 bit MSB not 16 bit MSB.
3128 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Ok, rewrote the logic of the re-key and now it seems to work.
3131 I tested it on high traffic with frequent re-keys without
3132 problems. Added hmac_receive (and renamed hmac to hmac_send)
3133 in SilcClientConnection in lib/silcclient/client.h and
3134 in SilcIDListData in silcd/idlist.h. Also, removed the
3135 SilcPacketParserContext's cipher and hmac fields as they are
3136 not needed anymore and actually caused some problems when
3137 the ciphers and hmac's changed underneath the packet parser.
3139 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * If re-key protocol is active then process the incoming packets
3142 synchronously since we must assure that icoming packets encrypted
3143 with the old key is processed before the new keys is set to
3144 use. This is true other packets than for REKEY packets.
3145 Affected file silcd/server.c. The same was done to client library
3146 as well, affected file lib/silcclient/client.c.
3148 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Fixed bug in client and server to accept the force send if
3151 the packet is send from silc_[server/client]_packet_process
3152 function. Otherwise the packets are never delivered, oops.
3154 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Disable force sending of packets when REKEY protocol is active.
3157 We must assure that no packet is sent directly when rekey is
3158 performed. All packets must be sent through packet queue.
3159 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3160 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3161 function is silc_[server/client]_packet_send_real to check
3164 * Replaced the SIM paths from example config files to
3165 /usr/local/modules. Also, make install creates now
3166 /usr/local/silc/logs directory to hold all the SILC server
3169 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Made the configure.in.pre work on Solaris. Patch by salo.
3173 * Made all ciphers compatible with non-x86 machines. Defined
3174 CBC mode macros into lib/silccrypt/ciphers_def.h.
3176 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Fixed the make install.
3180 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * When MAC computation fails the silc_packet_decrypt returned 0
3183 even though it was supposed to return -1. Fixed this. The
3184 affected file is lib/silccore/silcpacket.c.
3186 * Do not replace the config files in /etc/silc (in make install)
3187 if they already exist. Affected file ./Makefile.am.
3189 * Do not send re-key packets immediately but through packet queue.
3190 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3192 * Changed silc_net_check_host_by_sock to return FALSE if the
3193 IP/DNS could not be resolved. Though, it returns the IP address
3194 now even if it could not resolve it (but returns also FALSE).
3195 Affected file lib/silcutil/silcnet.[ch].
3197 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Added silc_pkcs_decode_identifier to decode the public key's
3200 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3201 Added also silc_pkcs_free_identifier. Added also new context
3202 SilcPublicKeyIdentifier.
3204 * Added -S option to the silc client. It is used to dump the
3205 contents of the specified public key file.
3207 * Changed the PKCS api to return the public key length when
3208 setting the public key.
3210 * Fixed a fatal bug in the public and private key file loading.
3211 Affected file lib/silccrypt/silcpkcs.c.
3213 * Execute the packet parsing for client with zero (0) timeout
3214 if the protocol is active. Affected file silcd/server.c.
3216 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Made the key generation options to the silcd program. Added
3219 -C option, equivalent to client's option.
3221 * Added new [ServerKeys] config section to the server. It
3222 configures the server's public and private key.
3224 * Defined generic Public Key Payload into the protocol
3225 specification to send specific type of public keys and
3228 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3229 public key or certificate.
3231 * Implemented the GETKEY command to the server and to the
3232 client library and on user interface.
3234 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Made preliminary `make install' work.
3238 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Added SilcServerRekey context into silcd/idlist.h.
3242 * Added the PFS support as defined in the specification to the
3243 SKE protocol. Affected files lib/silcske/*.c.
3245 * Added `ske_group' field to the SilcServerRekey context to hold
3246 the number of the SKE group that is used with PFS in re-key.
3247 Affected file silcd/idlist.h.
3249 * Added PFS re-key support to the server. Affected file is
3252 * Added silc_protocol_cancel to cancel execution of the next
3253 state of the protocol. Affected file is
3254 lib/silccore/silcprotocol.[ch].
3256 * Added the re-key support with and without PFS to the client
3257 library. Re-key is performed once in an hour, by default.
3259 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3260 Added silc_client_rekey_callback and silc_client_rekey_final.
3261 Affected files are lib/silcclient/protocol.[ch] and
3262 lib/silcclient/client.[ch].
3264 * Removed the `hmac_key' and `hmac_key_len' fields from the
3265 SilcClientConnection structure; not needed. Affected file is
3266 lib/silcclient/client.h.
3270 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Do not ask whether user wants to use the negotiated private key
3273 for private messages, just use it. Affected file is
3274 silc/local_command.c.
3276 * Added `send_enc_key' and `enc_key_len' fields to the
3277 SilcIDListData structure since they are needed in the re-key
3278 phase. Affected file is silcd/idlist.[ch].
3280 * Implemented the simple re-key protocol into the server.
3281 Affected files silcd/server.c and silcd/protocol.[ch]. The
3282 re-key will be performed once in an hour, by default.
3284 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3285 Added silc_server_rekey, silc_server_rekey_callback and
3286 silc_server_rekey_final.
3288 * Removed Tunneled flag from the protocol. Updated the code
3289 and the specifications.
3291 * Adde `pfs' field to the SilcIDListData to indicate whether
3292 the PFS is to be performed in the re-key. Affected file is
3295 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3298 int64 of at least the xintXX size. If void * is less that 4
3299 bytes uint32 * will be used. Defined bool as boolean.
3301 * Changed _ALL_ unsigned long and unsigned int to uint32,
3302 unsgined short to uint16 in the source tree.
3304 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3305 not handle clients that has entry->data.registered == FALSE.
3306 They are not in the network anymore. Affected file is
3309 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Implemented the sending of the SERVER_SIGNOFF notify in the
3312 server. Affected file is silcd/server.c.
3314 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3315 Added also silc_notify_payload_encode_args into the
3316 lib/silccore/silcnotify.[ch].
3318 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3319 Affected file silcd/packet_receive.c.
3321 * Implemented the SERVER_SIGNOFF notify handling in the client
3322 library. Affected file lib/silcclient/client_notify.c. Also,
3323 implemnted the printing of the SERVER_SIGNOFF info to the
3324 application. Affected file silc/client_ops.c.
3326 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3327 if the deleting was successful. Affected file silcd/idlist.[ch].
3329 * Added support for public key authentication in the connection
3330 authentication protocol in the client library. Affected file
3331 lib/silcclient/protocol.c.
3333 * Changed the server's silc_idlist_get_clients_by_* interface
3334 to support already allocated array so that new entries may be
3335 added to pre-allocated array. Affected file silcd/idlist.[ch].
3336 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3337 and command replies.
3339 * All command reply functions in the server now calls the
3340 pending command callback even if error occured. This way the
3341 error will be delivered to the client as well. Affected files
3342 silcd/command.c and silcd/command_reply.c.
3344 * Fixed INFO command to return local server's info if no server
3345 was provided. Affected file lib/silcclient/command.c.
3347 * Removed RESTART command for good. Updated the code and the
3350 * Rewrote parts of the task system. It is a bit simpler now.
3351 Removed unsued task priorities. The affected files are
3352 lib/silcutil/silctask.[ch].
3354 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Moved the USERS printing from the library to the application.
3357 Affected files lib/silcclient/command.c and silc/client_ops.c.
3359 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3363 * Added channel key re-key support. The re-key is perfomed
3364 only by the router and is done once in an hour. Added `rekey'
3365 field to the SilcChannelEntry in the server. Affected files
3366 silcd/server.c and silcd/idlist.h.
3368 * Added silc_task_unregister_by_context into the file
3369 lib/silcutil/silctask.[ch].
3371 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Added SILC_UMODE_GONE mode to indicate when the client is not
3374 present in the SILC network. Added also support to the local
3375 command AWAY that will set this mode. Added support of showing
3376 "xxx is gone" in WHOIS command. The USERS command shows the
3377 gone status as well.
3379 * Fixed setting server and router operator privileges in the
3380 server's UMODE command. Affected file silcd/command.c.
3382 * Merged the SKE KE1 and KE2 payloads into one payload. The
3383 new KE payload is equivalent to the old KE2 payload.
3385 Cleaned up the SKE Start Payload parsing. It now uses the
3386 simple buffer unformatting to do the parsing. A lot faster
3389 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3390 to the SKE that is used to indicate whether both of the SKE
3391 parties should perform authentication. By default only the
3392 responder performs authentication. By setting this flag also
3393 the initiator must do authentication. By default it is unset
3394 since in normal SKE case, client to server connection, only
3395 the responder should do authentication. When doing SKE between
3396 two clients both should perform authentication. Updated the
3397 code and the protocol specs.
3399 * A little fix to IDENTIFY command in the server. Search the
3400 client first by hash not nickname. Affected file is
3403 * Fixed the silc_client_close_connection to support closing
3404 the client to client connections wihtout deleting too much
3405 data. Affected file lib/silcclient/client.c.
3407 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3408 are received if protocol used to be active but is not anymore
3409 the application would crash due to NULL pointer dereference.
3410 Affected files silcd/server.c and lib/silcclient/client.c.
3412 * Added `hash' field to the SilcClientConnection to include
3413 the hash function negotiated in the SKE protocol.
3415 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3416 to set the channel founder authentication data. A client can
3417 claim the founder rights later by providing the authentication
3418 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3419 This way the channel founder can regain the channel founder
3420 privileges even it is left the channel. This works only on
3421 local server and the client must be connected to the same
3422 server to be able to regain the founder rights. Updated the
3423 protocol specs accordingly.
3425 Added support to the CMODE command in the client to set the
3426 founder auth data. Read the README to see how to set it.
3428 Added support to the CUMODE command to claim the founder
3429 rights. Read the README to see how to do it.
3431 Added support for the founder authentication to the Channel
3432 Entry in the server. Affected file silcd/idlist.h.
3434 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3435 server's CMODE command. Affected file silcd/command.c.
3437 * Added the following new functions into lib/silccore/silcauth.[ch]:
3438 silc_auth_get_method and silc_auth_get_data.
3440 * The server now saves the remote hosts public key to the
3441 SilcIDListData pointer. Affected file silcd/protocol.c.
3443 * The normal server now does not remove the channel entry from
3444 the cache if the founder authentication data is set. It used
3445 to remove it if the founder was the last one on the channel on
3446 the server and left the channel. The auth data is saved and
3447 if the channel is re-joined later the old entry is used with
3448 the old auth data. Affected files silcd/command_reply.c and
3451 * Removed the `pkcs' field from the SilcIDListData structure
3452 in the server; it is not used. Affected file silcd/idlist.h.
3454 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3456 * Fixed packet processing on slow links. Partial packets were
3457 never re-processed because the incoming data buffer was cleared
3458 by the application. Application must not directly clear the
3459 sock->inbuf, the packet processing routines handle it. Fixed
3460 this in client library and in server.
3462 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Fixed the WHOIS and IDENTIFY send reply function to really
3465 check whether to send list or just one entry. Affected file
3468 * Cleaned up the LEAVE command's channel key distribution. The
3469 affected file silcd/command.c.
3471 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3472 can enforce the channel mode as well. In that case the ID
3473 includes the ID of the server. The code now enforces the
3474 mode change if the router have different mode than the server.
3476 * The notify client operation with CMODE_CHANGE notify can now
3477 return NULL client_entry pointer if the CMODE was not changed
3478 by client. Application must check for this.
3480 * Added <Server ID> argument to INFO command to support server
3481 info fetching by Server ID.
3483 * Added silc_server_announce_get_channel_users to get assembled
3484 packets of channel users of the specified channel. Affected
3485 file silcd/server.[ch].
3487 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3488 was freed underneath the ID Cache.
3490 * Re-announce clients when the server received CHANNEL_CHANGE
3491 notify from the router. Affected file silcd/packet_send.c.
3493 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3496 crashed since it did not handle the fact that there is no cipher
3497 called "3" and didn't check the error condition. Now fixed.
3499 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3500 flag. It can be used to send message requests.
3502 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Implemented the RESTART command in the client.
3506 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3507 notice type messages. Added notice printing to the user
3510 * The channel keys are not re-generated if the channel's mode
3511 is PRIVKEY, ie private key on the channel exists. Affected
3512 files silcd/server.c and silcd/command.c.
3514 * Fixed a little bug in channel message delivery when channel
3515 private keys are set in the server. Affected file is
3516 silcd/packet_send.c.
3518 * Changed the setting on channel->on_channel = TRUE from the
3519 silc_client_save_channel_key to the JOIN command reply. The
3520 key payload is not received if the private channel key is set.
3521 Affected file lib/silcclient/command_reply.c and the
3522 lib/silcclient/client_channel.c.
3524 * When the CMODE_CHANGE notify is sent and the channel private
3525 key mode is removed the channel key must be re-generated in
3526 other cells as well. Added this support for the router in the
3527 silcd/packet_receive.c.
3529 * Added new local command NOTICE to send notice message on
3530 channel. Affected file silc/local_command.[ch].
3532 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Added new local command ME to the client. It is used to send
3535 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3536 some action. Affected file silc/local_command.[ch].
3538 * Changed channel_message and private_message client operations
3539 to deliver the message flags to the application. Added also
3540 the `flags' arguments to the silc_client_send_channel_message
3541 and silc_client_send_private_message functions. Affected file
3544 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Redefined the Private Message Payload to support private message
3547 keys and to support the new private message flags. Updated
3548 the protocol specs. Flags makes it possible to have for example
3549 CTCP style messages.
3551 * Added new type SilcPrivateMessagePayload and defined an API
3552 for it in the lib/silcclient/silcprivate.[ch].
3554 * Tested private message private keys successfully. Tested the
3555 private message key set, unset and list commands with the new
3558 * Redefined the Channel Message Payload to include the channel
3559 message flags (equal with private message flags) to support
3560 for example CTCP style messages.
3562 * Defined some of the message (for channel and private message)
3563 flags. Updated the protocol specs and added the flags to the
3564 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3566 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Added SilcKeyAgreementStatus type to the key agreement routines
3569 to indicate the current status and error if one occured.
3570 The status types are defined in the lib/silcclient/silcapi.h.
3572 * Added new local command KEY that is used to set and unset private
3573 keys for channels, set and unset private keys for private messages
3574 with remote clients and to send key agreement requests and
3575 negotiate the key agreement protocol with remote client. The
3576 key agreement is supported only to negotiate private message keys,
3577 it currently cannot be used to negotiate private keys for channels,
3578 as it is not convenient for that purpose.
3580 * Fixed a minor pending callback setting bug in the function
3581 silc_client_get_client_by_id_resolve, now the function works.
3582 Affected file lib/silcclient/idlist.c.
3584 * Added function silc_net_get_local_port to get local bound
3585 port by socket. Added to lib/silcutil/silcnet.[ch].
3587 * Added `sockets' and `sockets_count' fields to the SilcClient
3588 object. They hold the sockets of the listenning sockets in
3589 the client. Listenning sockets may be for example the key
3590 agreement server. Affected file lib/silcclient/client.[ch].
3591 Added functions the silc_client_add_socket and the
3592 silc_client_del_socket. They are exported to the application
3595 * Added ~./silc/clientkeys to support other client's public keys.
3597 * Renamed verify_server_key client operation to verify_public_key
3598 and added one argument to indicate the type of the connection
3599 (server, client etc.).
3601 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Added silc_server_connection_auth_request to handle the
3604 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3605 silcd/packet_receive.[ch].
3607 * Added silc_server_send_connection_auth_request into the
3608 silcd/packet_send.c to send the connection auth request packet.
3610 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3613 * Fixed the public key authentication in responder side in the
3614 server. The `auth_data' pointer includes the SilcPublicKey
3615 not the path to the public key. Affected file silcd/protocol.c.
3617 * Implemented the public key authentication in the initiator side
3618 in the server. Affected file silcd/protocol.c.
3620 * Removed the [RedirectClient] config section from the server
3621 configuration. Is not needed and I don't want to implement it.
3623 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Cleaned up the CMODE command in the server. It now works
3626 correctly and supports all the modes defined in the protocol.
3627 Affected file is silcd/command.c.
3629 * Added `hmac_name' field to the SilcChannelEntry in the server
3630 to hold the default HMAC of the channel. It can be set when
3631 creating the channel (with JOIN command). Affected files
3634 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3635 type to indicate the change of the current cipher and hmac
3636 on the channel. Client can safely ignore the <cipher> argument
3637 (if it chooses to do so) since the CHANNEL_KEY packet will
3638 force the channel key change anyway. The <hmac> argument is
3639 important since the client is responsible of setting the new
3640 HMAC and the hmac key into use.
3642 * Fixed the CMODE command in the client library as well.
3644 * Tested CMODE command in router environment successfully.
3646 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Show the version of the remote client (or server) when connecting
3649 to the server. It is logged to the log file. Affected file
3650 is silcd/protocol.c.
3652 * Fixed the KILLED notify handling in the client library. The
3653 client must be removed from all channels when receiving the
3656 Also, do not remove the client entry when giving the KILL
3657 command but when the KILLED notify is received.
3659 * Removed silc_idlist_find_client_by_nickname from the server.
3660 Not needed anymore. Affected files silcd/idlist.[ch].
3662 * Implemented the CHANNEL_CHANGE notify type handling to the
3663 server. Affected file silcd/server.c.
3667 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Added silc_server_send_notify_invite to send the INVITE
3670 notify between routers.
3672 * Implemented the INVITE command correctly to the server.
3674 * Implemented the INVITE notify type handling in the server.
3676 * Implemented the INVITE command to the client library and on the
3679 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Added function silc_server_get_client_resolve to find the
3682 client entry by ID from all ID lists and then resolve it
3683 (using WHOIS) if it cannot be found. Affected file is
3686 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Implemented the BAN command to the client library.
3690 * The JOIN command in the server now checks the invite list
3693 * Changed the silc_command_reply_payload_encode_va and the
3694 silc_command_payload_encode_va to support that if argument is
3695 NULL it ignores and checks the next argument. Affected file
3696 lib/silccore/silccommand.c.
3698 * Added silc_server_send_notify_ban to send the BAN notify
3699 type between routers.
3701 * Chaned the silc_notify_payload_encode to support that if
3702 argument is NULL it ignores and checks the next argument.
3703 Affected file lib/silccore/silcnotify.c.
3705 * Tested ban lists in router environment successfully.
3707 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Implemented BAN command to the server, in silcd/command.[ch].
3711 * Removed the BAN and INVITE_LIST modes from the CMODE command
3714 * Added function silc_string_match to regex match two strings.
3715 Affected files lib/silcutil/silcutil.[ch].
3717 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Redefined parts of the SilcChannelEntry in the server to support
3720 the new ban and invite lists.
3722 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Redefined the INVITE command. The same command can be used to
3725 invite individuals to the channel but also to manage the invite
3726 list of the channel (to add to and remove from the invite list).
3727 Updated the protocol specs.
3729 * Added new command SILC_COMMAND_BAN that can be used to manage
3730 the ban list of the channel. Updated the protocol specs.
3732 * Removed the channel modes: the SILC_CMODE_BAN and the
3733 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3734 in the CMODE command. The equivalent features are now available
3735 using INVITE and BAN commands. Updated the protocol specs.
3737 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3738 in the network about change in the current ban list. The notify
3739 type is not used by the client.
3741 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3742 support the invite lists.
3744 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Added new function silc_string_regexify that converts string
3747 including wildcard characters into regex string that can
3748 be used by the GNU regex library. Added into the file
3749 lib/silcutil/silcutil.[ch].
3751 Added silc_string_regex_combine to combine to regex strings
3752 into one so that they can be used as one regex string by
3753 the GNU regex library. Added into the file
3754 lib/silcutil/silcutil.[ch].
3756 Added silc_string_regex_match to match two strings. It returns
3757 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3759 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Imported GNU regex to the soruce tree into lib/contrib.
3762 Fixed some compiler warning from the regex.c.
3764 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Fixed MOTD command in the server to work in router environment.
3768 * Fixed the MOTD command in the client library to support
3769 the server argument in the command.
3771 * Added `nickname_len' argument to the silc_idlist_add_client
3772 in the server, as the `nickname' argument may be binary data
3775 * Added silc_idlist_get_channels to return all channels from
3778 * Implemented LIST command to the server. Affected file is
3781 * Implemented the LIST command to the client library and on the
3784 * Added [<user count>] argument to the LIST command reply.
3785 With private channels the user count is not shown.
3787 * Updated TODO and README.
3789 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * The client entry's data.registered must be TRUE even with
3792 global client entry on global client list. The data.registered
3793 is used to check whether the client is anymore in the network,
3794 for example with WHOWAS command so it must be valid.
3796 * Fixed the WHOWAS command in the server. It now actually works
3797 in router environment. Added function into silcd/command_reply.c
3798 silc_server_command_reply_whowas_save.
3800 * Added silc_idlist_purge function to the silcd/idlist.c
3801 to periodically purge the ID Cache.
3803 * Fixed INFO command in the server. It works now in router
3804 environment. Added <server name> argument to the INFO command
3805 reply. Updated the protocol specs.
3807 * Fixed minor bug in silc_idcache_purge to not purge if the
3808 expire value is zero.
3810 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3811 they were buggy because of the WHOWAS information.
3813 * Fixed local command MSG to handle the async resolving of
3814 the remote client properly. It used to fail the first MSG.
3815 Affected file silc/local_command.c.
3817 * Added `data_len' field to SilcIDCache context.
3819 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Update TODO. Todo in commands in the server.
3823 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3826 used by routers as broadcast packet to inform other routers
3827 about the changed user mode.
3829 Implemented the notify handling in the server. Affected file is
3830 silcd/packet_receive.c. Added the function
3831 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3833 * Added new generic Channel Payload and deprecated the New Channel
3834 Payload. The New Channel Payload is now the generic Channel
3837 * Added new argument `mode' to the silc_server_send_new_channel
3838 as it is required in the Channel Payload now.
3840 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3841 and created a new and real SilChannelPayload to represent the
3842 new generic Channel Payload. Implemented the encode/decode
3843 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3845 * Added silc_server_get_client_channel_list to return the list
3846 of channels the client has joined for WHOIS command reply.
3847 Affected file silcd/server.[ch].
3849 * Implemented the channel list sending in the WHOIS command reply
3850 in server and in the client.
3852 Implemented the channel list displaying on the user interface
3853 as well. Affected file silc/client_ops.c.
3855 * Added silc_channel_payload_parse_list to parse list of Channel
3856 Payloads. It returns SilcDList list of SilcChannelPayloads.
3857 Client for example can use this function to parse the list of
3858 channels it receives in the WHOIS command reply. The caller
3859 must free the list by calling silc_channel_payload_list_free.
3860 Affected files lib/silccore/silcchannel.[ch].
3862 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added one new argument <user mode> to the WHOIS command reply
3865 to return the mode of the user in SILC. Updated the protocol
3868 Implemented it to the server and client.
3870 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Fixed the mode printing on the user interface on joining.
3873 Affected file silc/client_ops.c.
3875 * Implemented the UMODE command and user modes in general to the
3876 client library and to the user interface.
3878 * Implemented the UMODE command to the server.
3880 * The server now sends UNKNOWN_COMMAND error status if client sends
3881 unknown command. Affected file silcd/command.c.
3883 * All server commands now handle the command identifier the right
3884 way when sending the command reply to the client. The client can
3885 use to identify the command replies with the identifier.
3887 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Added silc_server_get_client_route to resolve the route to
3890 the client indicated by the client ID. Affected file is
3893 * Added silc_server_relay_packet as general function to relay
3894 packet to arbitrary destination. This deprecates functions
3895 like _send_private_message_key, _relay_notify etc. Affected
3896 file is silcd/packet_send.[ch].
3898 Removed silc_server_send_key_agreement,
3899 silc_server_send_private_message_key and
3900 silc_server_packet_relay_notify functions from the file
3901 silcd/packet_send.[ch].
3905 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3906 server. Affected file silcd/packet_receive.[ch].
3908 * Implemented the KILL command to the client. Implemented the
3909 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3910 Affected files lib/silcclient/command[_reply].c and
3911 lib/silcclient/client_notify.c. Implemented the KILL notify
3912 printing in the user inteface.
3914 * Fixed a lot silc_parse_nick memory leaks from the client
3915 library in the file lib/silcclient/command.c.
3917 * Changed the silc_server_send_notify_on_channels's `sender'
3918 argument from SilcSocketConnection to SilcClientEntry to
3919 check the sender as entry and not as connection object and not
3920 to send to the client provided as argument. The affected file
3921 is silcd/packet_send.[ch].
3923 * The notify packets that are destined directly to the client used
3924 to not to be processed by the server. Now changed that and the
3925 server processes all notify packets. After relaying the packet
3926 to the client the notify packet is processed in the server.
3928 * The silc_server_free_client_data now checks whether there is
3929 pending outgoing traffic for the client and purges the data to
3930 the network before removing the client entry.
3932 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3934 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3935 an client is killed from the SILC Network. Updated the protocol
3938 Added new function silc_server_send_notify_killed to the
3939 silcd/packet_send.[ch].
3941 * Added function silc_server_packet_relay_notify to relay notify
3942 packets that are destined directly to a client. In this case
3943 the server does not process the notify packets but merely relays
3944 it to the client. Affected file silcd/packet_send.[ch].
3946 Added also silc_server_packet_process_relay_notify to check
3947 whereto relay the notify. Affected file is
3948 silcd/packet_receive.[ch].
3950 * Implemented the KILL command to the server.
3954 * Added the backup schema desgined last fall to the protocol
3955 specs for everyone to see. The specification is in the
3956 *-spec-xx.txt draft and the packet type definitions for the
3957 backup routers is in *-pp-xx.txt draft. Thusly, added also
3958 new packet type SILC_PACKET_CELL_ROUTERS.
3960 * A big security problem in the implementation discovered. The
3961 signoff of an client did not cause new channel key generation
3962 which it of course should've done. The channel keys must be
3963 always re-generated when client leaves (or signoffs) the channel.
3964 The silc_server_remove_from_channels funtion now handles
3965 the channel key re-generation.
3967 * Added `sender' argument to the silc_server_send_notify_on_channels
3968 to not to send the client provided as argument. Affected file
3969 silcd/packet_send.[ch].
3971 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Implemented OPER and SILCOPER commands into the server and
3976 * Added silc_auth_verify and silc_auth_verify_data to verify
3977 the authentication directly from the authentication payload.
3978 It supports verifying both passphrase and public key based
3979 authentication. Affected file lib/silccore/silcauth.[ch].
3981 * Added `hash' field to the SilcIDListData structure. It is the
3982 hash negotiated in the SKE protocol. Affected file is
3985 * Slight redesigning of the SilcAuthPayload handling routines.
3986 Do not send SilcPKCS but SilcPublicKey as argument.
3988 * Implemented the public key authentication support to the
3989 serverconfig. The public key is loaded from the provided path
3990 and saved as authentication data to void * pointer. Thus,
3991 changed the unsigned char *auth_data to void *auth_data;
3993 * Fixed SHUTDOWN command to send the reply before the server
3994 is shutdown. :) Affected file silcd/command.c.
3996 * Fixed fatal bug in CONNECT command. The hostname was invalid
3997 memory and server crashed. Affected file silcd/command.c.
3999 * Fixed fatal bug in CLOSE command. The server_entry became
4000 invalid but was referenced later in the command. Affected file
4003 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Fixed fatal bug in failure packet handling. Server ignored
4006 the failure and thus crashed when it came.
4010 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4013 that the command may be executed only once in (about) 2 seconds.
4014 The old SILC_CF_LAG flag is same but allows command bursts up
4015 to five before limiting.
4017 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4018 server code. Various commands now includes the CF_LAG_STRICT
4019 flag to disallow any kind of miss-use of the command.
4021 * Fixed the silc_buffer_unformat to not to allocate any data
4022 if the length of the data is zero. It used to allocate the
4023 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4025 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Changed the format of AdminConnection configuration section
4028 in the server. Added username of the admin to the format.
4029 Affected files silcd/serverconfig.[ch].
4031 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4032 to return admin configuration data by host, username and/or
4035 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Implemented WHOWAS command to the server. Added the functions:
4039 silc_server_command_whowas_parse,
4040 silc_server_command_whowas_send_reply,
4041 silc_server_command_whowas_from_client and
4042 silc_server_command_whowas_from_server
4044 * Added <Client ID> argument to the WHOWAS command reply. Updated
4045 the protocol specs accordingly.
4047 * Implemented WHOWAS command and command_reply to the client
4050 Implemented the WHOWAS printing on the user interface.
4052 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Added new argument to the WHOWAS command reply, the real name.
4055 It is an optional argument. Updated the protocol specs.
4057 * Added SilcIDCacheDestructor callback that is registered when
4058 the SilcIDCache is allocated. The callback is called when
4059 an cache entry in the ID Cache expires, or is purged from the
4060 cache. Added into lib/silccore/idcache.[ch].
4062 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4063 to destruct the client entries when the cache entry expires.
4064 Other ID Cache's in server and in the client library ignores
4067 * If the ID Cache entry's `expire' field is zero then the entry
4068 never expires. Added boolean `expire' argument to the
4069 silc_idcache_add function in the lib/silccore/idcache.[ch].
4070 If it is TRUE the default expiry value is used.
4072 * Added silc_server_free_client_data_timeout that is registered
4073 when client disconnects. By default for 5 minutes we preserve
4074 the client entry for history - for WHOWAS command.
4076 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Added support to the server to enforce that commands are not
4079 executed more than once in 2 seconds. If server receives
4080 commands from client more frequently, timeout is registered
4081 to process the commands. Affected file silcd/command.c.
4082 Added new function silc_server_command_process_timeout.
4084 * Changed NICK_NOTIFY handling in client library to check that
4085 if the client's nickname was changed, so there is no need to
4086 resolve anything from the server.
4088 * Removed error printing from the WHOIS and IDENTIFY commands.
4089 If error occurs then it is ignored silently in the client library.
4090 The application, however, may map the received error to
4091 human readable error string. The application currently maps
4092 the NO_SUCH_NICKNAME error to string.
4094 * Made the command status message public to the application. Moved
4095 them from lib/silcclient/command_reply.c to
4096 lib/silcclient/command_reply.h. The application can map the
4097 received command status to the string with the
4098 silc_client_command_status_message function.
4100 * Added check to the server to check that client's ID is same
4101 as the Source ID in the packet the client sent. They must
4104 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Added dist-bzip hook to the Makefile.am to make bzip2
4107 compressed distributions.
4109 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Server now enforces the maximum length for the nickname and
4112 the channel as protocol specification dictates. 128 bytes for
4113 nickname and 256 bytes for channel name.
4115 * Moved the WHOIS printing to the application. The client libary
4116 does not print out the WHOIS information anymore, the application
4117 must do it. Renamed silc_client_command_reply_whois_print to
4118 the silc_client_command_reply_whois_save.
4120 The client's idle time is also sent to the application now, and
4121 the idle is shown on screen.
4123 * Added silc_client_command_reply_identify_save to save the
4124 received IDENTIFY entries.
4126 * Do not check for channel private keys in message sending and
4127 reception if the channel does not have the PRIVKEY mode set.
4128 Affected file lib/silclient/client_channel.c.
4130 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4133 just surfaced after chaning the JOIN procedure.
4135 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added silc_client_get_clients_by_list to get client entries
4138 from Client ID list, that is returned for example by JOIN
4139 and USERS command replies. The application should use this
4140 function for example when JOIN command reply is received to
4141 resolve the clients already on the channel (library does not
4142 do that anymore as USERS command reply is not used in the JOIN
4143 procedure anymore). Affected files lib/silcclient/silcapi.h and
4144 lib/silcclient/idlist.c.
4146 * JOIN command reply and USERS command reply returns now SilcBuffer
4147 pointers instead of unsigned char pointers when returning
4148 the client list and mode list.
4150 * Added <Client ID> argument to the JOIN command reply, mainly
4151 for the server to identify for which client the command was
4152 originally sent. Updated protocol specs accordingly.
4154 * Added SilcDlist private_key pointer to the SilcChannelEntry
4155 in the client to support the channel private keys. Affected
4156 file is lib/silcclient/idlist.h.
4158 * Added SilcChannelPrivateKey argument to the function
4159 silc_client_send_channel_message so that application can choose
4160 to use specific private ke if it wants to. If it is not provided,
4161 the normal channel key is used, unless private keys are set.
4162 In this case the first (key that was added first) is used
4163 as the encryption key.
4165 * Implemented the support for channel private key handling.
4166 Implemented the following functions:
4168 silc_client_add_channel_private_key,
4169 silc_client_del_channel_private_keys,
4170 silc_client_del_channel_private_key,
4171 silc_client_list_channel_private_keys and
4172 silc_client_free_channel_private_keys
4174 Affected file lib/silcclient/client_channel.c.
4176 * Added the support for the private keys in the channel message
4177 sending and encryption and in the message reception and
4178 decryption. Affected funtions are
4179 silc_client_send_channel_message and silc_client_channel_message.
4181 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Added SKE's key verify callback to the client library's
4184 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4186 * Removed the statement that server (or router) must send USERS
4187 command reply when joining to the channel so that the client
4188 knows who are on the channel. Instead, the client list and
4189 client's mode list is now sent in the JOIN command reply to the
4190 client who joined channel. This is better solution.
4192 * Added function silc_server_get_users_on_channel and function
4193 silc_server_save_users_on_channel to the silcd/server.[ch].
4195 * Removed function silc_server_command_send_users from the
4198 * Do not show topic on the client library anymore. The topic is
4199 sent in the command reply notify to the application and the
4200 application must show the topic now.
4202 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Added client searching by nickname hash into the IDENTIFY and
4205 WHOIS commands in the server as they were clearly missing from
4206 them. Affected file is silcd/command.c.
4208 * Fixed a bug in private message receiving in the client library.
4209 The remote ID was freed and it wasn't supposed, now it is
4212 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Minor fix to the channel payload; allocate the data area, as it
4215 needs to be of specific length.
4217 * If the key agreement port is zero then the operating
4218 system will define the bound port. Affected files are
4219 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4221 * Added new function silc_channel_payload_decrypt into the file
4222 lib/silccore/silcchannel.[ch].
4224 * Moved the channel message etc, check from silc_packet_decrypt
4225 to applications. The library calls now a generic
4226 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4227 when the packet is either normal or special. This was done to
4228 allow more wide range of checking that was not allowed when
4229 the code was in library. Now applications can do virtually any
4230 checks to the packet and return to the library the decision how
4231 the packet should be processed. Affected files are
4232 lib/silccore/silcpacket.[ch].
4234 Added silc_server_packet_decrypt_check to the server and
4235 silc_client_packet_decrypt_check to the client library.
4237 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4238 to send with specified source and destination information.
4240 * Channel message delivery between routers was broken after the
4241 channel key distribution was fixed earlier. The channel key
4242 was used be to distributed to other routers as well which is not
4243 allowed by the protocol. Now this is fixed and channel keys
4244 really are cell specific and the channel message delivery between
4245 routers comply with the protocol specification.
4247 * Fixed various commands in server to check also the global list
4248 for the channel entry and not just the local list. The affected
4249 file silcd/command.c.
4251 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Added assert()s to buffer formatting and unformatting routines
4254 to assert (if --enable-debug) when error occurs. Affected
4255 file: lib/silcutil/silcbuffmt.c.
4257 * Changed to auto-reconnect to check whether the remote host is
4258 router and register the re-connect timeout if it is. It used
4259 to check that whether we are normal server, but router must do
4260 auto-reconnect with another router as well. Affected file
4263 * Removed the [<key len>] option from CMODE command as the cipher
4264 name decides the key length, nowadays. See the defined ciphers
4265 from the protocol specification.
4267 * Added [<hmac>] option to the CMODE command to define the HMAC
4268 for the channel. Added SILC_CMODE_HMAC channel mode.
4270 * Added [<hmac>] option for the JOIN command so that user can
4271 select which HMAC is used to compute the MACs of the channel
4274 * Added Hmac field to the Channel Message Payload. The integrity
4275 of plaintext channel messages are now protected by computing
4276 MAC of the message and attaching the MAC to the payload. The
4277 MAC is encrypted. Now, it is clear that this causes some
4278 overhead to the size of the packet but rationale for this is that
4279 now the receiver can verify whether the channel message decrypted
4280 correctly and also when private keys are set for the channel the
4281 receiver can decrypt the packet with several keys and check from
4282 the MAC which key decrypted the message correctly.
4284 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4285 lib/silccrypt/silccipher.[ch].
4287 * Added silc_hash_len to return the digest length into the
4288 lib/silcrypt/silchash.[ch].
4290 * Rewrote parts of Silc Channel Payload interface in the
4291 lib/silccore/silcchannel.[ch]. The encode function now also
4292 encrypts the packet and parse function decrypts it.
4294 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Fixed a minor formatting bug in the SKE's key material processing.
4297 It actually might have processed the keys wrong way resulting
4300 * Redefined the mandatory HMAC algorithms and added new algorithms.
4301 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4302 and hmac-md5 truncated to 96 bits. The mandatory is now
4303 hmac-sha1-96. Rest are optional (including the one that used
4304 to be mandatory). Rationale for this is that the truncated HMAC
4305 length is sufficient from security point of view and can actually
4306 make the attack against the HMAC harder. Also, the truncated
4307 HMAC causes less overhead to the packets. See the RFC2104 for
4310 * Added new [hmac] configuration section. The SKE used to use
4311 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4312 is of course wrong. The official names that must be proposed in
4313 the SKE are the ones defined in the protocol specification
4314 (hmac-sha1-96 for example). The user can configure any hmac
4315 using any hash function configured in the [hash] section. At
4316 least, the mandatory must be configured.
4318 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4320 * Added HMAC list to the SKE proposal list. It has now both
4321 hash algorithm list and HMAC list. This makes the protocol
4322 incompatible with previous versions. The SKE now seems to work
4323 the way it is supposed to work, for the first time actually.
4325 * Defined plain Hash algorithms to the protocol specification.
4328 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Implemented support for key agreement packets into the server.
4331 Added functions silc_server_key_agreement and
4332 silc_server_send_key_agreement. Other than these functions,
4333 server has nothing to do with this packet.
4335 * Added support for private message key packets into the server.
4336 Added functions silc_server_private_message_key and
4337 silc_server_send_private_message_key.
4341 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4342 called in the protocol's final callback instead in the END
4343 protocol state. This makes a little more sense and in the same
4344 time in client we can use the same protocol routines for normal
4345 key exchange and to key agreement packet handling as well.
4347 * Added to both client's and server's KE protocol context the
4348 SilcSKEKeyMaterial pointer to save the key material. We will
4349 bring the key material to the protocol's final callback by doing
4350 this. The final callback must free the key material.
4352 * Added SKE's packet_send callback into client's KE protocol
4353 context so that the caller can choose what packet sending function
4354 is used. This way we can use different packet sending when
4355 doing normal SKE when doing key agreement packet handling (in
4356 the key agreement packet handling we do not want to encrypt
4359 * Implemented the responder side of the key agreement routines
4360 in the client. The client can now bind to specified port and
4361 accept incoming key negotiation. The key material is passed
4362 to the application after the protocol is over.
4364 * Implemented the processing of incoming Key Agreement packet
4365 in the client. Added function silc_client_key_agreement to
4368 * Implemented the intiator side of the key agreement routines
4369 in the client. The client can now initiate key agreement with
4370 another remote client. The key material is passed to the
4371 application after the protocol is over.
4373 * Created client_keyagr.c to include all the key agreement
4376 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4377 SILC_TASK_CALLBACK except that it is not static.
4379 * Created client_notify.c and moved the Notify packet handling
4380 from the client.[ch] into that file.
4382 * Created client_prvmsg.c and moved all private message and
4383 private message key routines from the client.[ch] into that file.
4385 * Create client_channel.c and moved all channel message and
4386 channel private key routines from the client.[ch] into that file.
4388 * Changed silc_client_get_client_by_id_resolve to resolve with
4389 WHOIS command instead of IDENTIFY command, in the file
4390 lib/silclient/idlist.c.
4392 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Implemented the SKE's responder side to the Client library.
4396 * When FAILURE is received to the protocol do not trust it
4397 blindly. Register a timeout to wait whether the remote closes
4398 the connection as it should do it, only after that process the
4399 actual failure. This was changed to both client and server.
4401 * Added client_internal.h to include some of the structures
4402 there instead of client.h in lib/silcclient/.
4404 * Added function silc_task_unregister_by_callback to unregister
4405 timeouts by the callback function.
4407 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Some "Incomplete WHOIS info" errors has been appearing on the
4410 log files. Took away the entry->userinfo check from WHOIS
4411 reply sending. The entry->userinfo is now " " if client did not
4412 provide one. I thought this was fixed earlier but something
4413 is wrong still. Let's see if the error still appears.
4415 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Fixed a minor bug in the login when the channel key is
4418 re-generated in the server. It used to generate the key in
4419 wrong order and thus caused problems in the channel traffic.
4421 * Fixed a minor bug in channel key distsribution after
4422 KICK command. The key was not sent to the router even though
4425 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Added silc_ske_process_key_material_data as generic routine
4428 to process any key material as the SILC protocol dictates. The
4429 function is used by the actual SKE library but can be used by
4430 applications as well. This relates to the private message keys
4431 and the channel private keys since they must be processed the
4432 same way the normal SILC session keys. The protocol dictates
4433 this. Affected files: lib/silcske/silcske.[ch].
4435 Added also silc_ske_free_key_material to free the
4436 SilcSKEKeyMaterial structure.
4438 * Defined silc_cipher_set_key function to set the key for
4439 cipher without using the object's method function. The affected
4440 files: lib/silccrypt/silccipher.[ch].
4442 * Implemented silc silc_client_add_private_message_key,
4443 silc_client_add_private_message_key_ske,
4444 silc_client_del_private_message_key,
4445 silc_client_list_private_message_keys and
4446 silc_client_free_private_message_keys functions in the
4449 Added functions silc_client_send_private_message_key to send
4450 the Private Message Key payload and silc_client_private_message_key
4451 to handle incoming Private Message Key payload.
4453 * Added Cipher field to the Private Message Key payload to set
4454 the cipher to be used. If ignored, the default cipher defined
4455 in the SILC protocol (aes-256-cbc) is used.
4457 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Removed lib/silcclient/ops.h file.
4461 Redefined parts of the SILC Client Library API. Created new
4462 file silcapi.h that deprecates the ops.h file and defines the
4463 published Client Library API. Defined also private message key
4464 API and channel private key API into the file.
4466 This is the file that the application must include from the
4467 SILC Client Library. Other files need not be included by
4468 the application anymore.
4470 * Added new key_agreement client operation callback and also
4471 defined the Key Agreement library API for the application.
4473 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4476 is used by clients to request key negotiation between another
4477 client in the SILC network. If the negotiation is started it
4478 is performed using the SKE protocol. The result of the
4479 negotiation, the secret key material, can be used for example
4480 as private message key.
4482 Implemented the Key Agreement payload into the files
4483 lib/silccore/silauth.[ch].
4485 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Redefined ciphers for the SILC protocol. Added some new ciphers
4488 and defined the key lengths for the algorithms. Changed the
4489 code accordingly. The default key length is now 256 bits.
4491 * Fixed SKE key distribution function silc_ske_process_key_material
4492 when the key length is more than 128 bits. The default key
4493 length in SILC is now 256 bits.
4495 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4496 to indicate unsupported algorithm.
4498 * Renamed rijndael.c to aes.c and all functions as well.
4500 * Fixed a long standing channel key setting bug in client library.
4501 Weird that it has never surfaced before.
4503 * Fixed bug in channel deletion. If the entire channel is removed
4504 then it must also delete the references of the channel entry
4505 from the client's channel list as the client's channel entry and
4506 the channel's client entry share same memory.
4508 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Implemented CONNECT and SHUTDOWN commands in the client.
4512 * Implemented CLOSE command to the client.
4514 * Added the function silc_idlist_find_server_by_name into the
4515 files silcd/idlist.[ch].
4517 Added the function silc_idlist_find_server_by_conn into the
4518 files silcd/idlist.[ch].
4520 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * DIE command was renamed to SHUTDOWN. Updated the both code
4525 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4526 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4528 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4531 * Added function silc_server_create_connection function to create
4532 connection to remote router. My server implementation actually
4533 does not allow router to connect to normal server (it expects
4534 that normal server always initiates the connection to the router)
4535 so the CONNECT command is only good for connecting to another
4538 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4541 or some other client was kicked from the channel.
4543 Implemented the handling of the notify type to both client
4546 Implemented silc_server_send_notify_kicked to send the KICKED
4547 notify. It is used to send it to the server's primary router.
4549 * Implemented the KICK command into server and client.
4551 * Added `query' argument to the silc_idlist_get_client function
4552 to indicate whether to query the client from server or not if
4555 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4556 to indicate that the client is not channel founder.
4560 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Removed the rng context from SilcPacketContext structure and
4563 changed that the packet routine uses the Global RNG API.
4565 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added support for quit message that client can "leave" on the
4568 channel when it quits the SILC. It is ditributed inside the
4569 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4571 Added silc_server_free_client_data that will take the
4572 signoff message as argument.
4574 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4576 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Updated parts of the protocol specification to keep it up
4581 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4584 payloads in one packet.
4586 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4587 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4588 use now the new List flag.
4590 * Also deprecated the following packet types: REPLACE_ID,
4591 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4593 * Added list support for Notify packet in server.
4595 * Added silc_server_send_notify_channel_change to send the
4596 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4597 the silc_server_send_replace_id.
4599 * Added silc_server_send_notify_nick_change to send the
4600 NICK_CHANGE notify type. Deprecates the function
4601 silc_server_send_replace_id.
4603 * Added silc_server_send_notify_join to send the JOIN notify type.
4604 Deprecates the function silc_server_send_new_channel_user.
4606 * Added silc_server_send_notify_leave to send LEAVE notify type.
4607 Deprecates the function silc_server_send_remove_channel_user.
4609 * Added silc_server_send_notify_cmode and
4610 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4611 types. Deprecates the silc_server_send_set_mode function.
4613 * Added SERVER_SIGNOFF notify type to indicate that server has
4614 quit. This means that all clients on the channel from that
4615 server will drop. This can be also used when netsplit happens.
4617 Deprecated REMOVE_ID packet type since it is not needed anymore
4620 Added silc_server_send_notify_server_signoff to send the
4621 SERVER_SIGNOFF notify type. Deprecates the function
4622 silc_server_send_remove_id.
4624 Added also silc_server_send_notify_signoff to send the
4625 SIGNOFF notify type.
4627 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4628 SILC protocol from this day on. Changed the protocol
4629 specification as well.
4631 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4632 notify type. It is used between routers to notify about
4633 topic changes on a channel.
4635 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4638 * Partly updated the protocol specification to comply with the
4639 changes now made. It is still though a bit outdated.
4641 * The JOIN notify type now takes one extra argument <Channel ID>.
4642 The packet used to be destined to the channel but now the
4643 JOIN type may be sent as list thus it is impossible to
4644 destine it to any specific channel. By adding this argument
4645 it is again possible.
4647 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Added CREDITS file. The CHANGES and CREDITS file will appear
4650 in the distribution as well.
4652 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4655 types in the server's silcd/packet_receive.c.
4657 * Implemented CMODE and CUMODE to work in router environment.
4659 * Fixed minor encoding and decoding buglet from the
4660 lib/silccore/silcmode.c.
4662 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4665 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4667 * Changed all SilcConfigServer* and silc_config_server* to
4668 SilcServerConfig* and silc_server_config*, respectively.
4671 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Associated the ID (client or server ID) to the Authentication
4674 Payload to avoid any possibility of forging. Updated the
4675 protocol specification and the code accordingly.
4677 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * The RSA key length is now save to the RsaKey context in the
4680 key generation process in lib/silccrypt/rsa.c. The key length
4681 is now used to figure out the maximum size of the block allowed
4682 to be encrypted/signed.
4684 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4685 is equivalent to the silc_mp_mp2bin but does not allocate any
4688 * Changed silc_mp_mp2bin API to take length argument. If it is
4689 non-zero then the buffer is allocated that large. If zero, then
4690 the size is approximated using silc_mp_sizeinbase, which however
4693 * Created Global RNG API which is global RNG that application can
4694 initialize. After initializing, any routine anywhere in the
4695 code (including library) can use RNG without allocating a new
4696 RNG object. This was done to allow this sort of use of the
4697 RNG in code that has no chance to allocate RNG object. All
4698 applications currently allocate this and many routines in the
4699 library use this. Affected file lib/silccrypt/silcrng.[ch].
4701 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4702 it to use the Global RNG API.
4704 * Defined Authentication Payload into protocol specification that
4705 is used during SILC session to authenticate entities. It is
4706 used for example by client to authenticate itself to the server
4707 to obtain server operator privileges.
4709 Implemented this payload into the lib/silccore/silcauth.[ch].
4710 Implemented also routines for public key based authentication
4711 as the new protocol specification dictates.
4713 Moved definitions of different authentication methods from
4714 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4716 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4717 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4718 silc_pkcs_verify_with_hash functions into the file
4719 lib/silccrypt/silcpkcs.[ch].
4721 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * The client entry's userinfo pointer must be always valid.
4724 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4725 will fail since it requires the userinfo. Now, the userinfo
4726 is allocated as "" if actual userinfo does not exist. Actually,
4727 it must exist and it is totally Ok to drop client connections
4728 that does not announce the userinfo. However, we will make
4729 this workaround for now.
4731 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4732 to return the remote port by socket.
4734 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4737 SILC_SERVER_PENDING_EXEC and added an new macro
4738 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4739 data or when error occurs while processing the pending command.
4741 Added new argument `destructor' into silc_server_command_pending
4742 and to the SilcServerCommandPending object. This destructor is
4743 now called after calling the pending callback or if error occurs
4744 immediately. If error occurs the actual pending callback won't
4745 be called at all - only the destructor. The destructor may be
4746 NULL if destructor is not needed.
4748 All this applies for client library code as well. Similar
4749 changes were made there as well for the pending commands.
4751 In the client, the application must now allocate the
4752 SilcClientCommandContext with the silc_client_command_alloc
4755 * Added reference counter to the SilcServerCommandContext. Added
4756 function silc_server_command_alloc and silc_server_command_dup
4759 Same type of functions added to the client library for the same
4762 * Removed the cmd_ident from IDListData away since it is now
4763 global for all connections. It is the command identifier used
4764 in command sending and with pending commands. The affected file
4767 * Added reference counter to the SilcSocketConnection objecet to
4768 indicate the usage count of the object. The object won't be
4769 freed untill the reference counter hits zero. Currently only
4770 server uses this, and client ignores it. The client must be
4771 set to use this too later. The affected files are
4772 lib/silccore/silcsockconn.[ch]. Added also the function
4773 silc_socket_dup to increase the reference counter.
4775 This was mainly added because it is possible that the socket
4776 is removed underneath of pending command or other async
4777 operation. Now it won't be free'd and proper DISCONNECTING
4778 flags, etc. can be set to avoid sending data to connection that
4779 is not valid anymore.
4781 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4782 the connection. After that it sets SILC_SET_DISCONNECTED.
4783 It is, however, possible that the socket data is not still freed.
4784 The silc_server_packet_process now checks that data is not
4785 read or written to connection that is DISCONNECTED. The socket
4786 get's freed when the reference counter hits zero.
4788 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Changed the client operation API: channel_message operation's
4791 `sender' is now the client entry of the sender, not the nickname
4792 and the `channel' is the channel entry, not the channel name.
4794 In the private_message operation the `sender' is now also the
4795 client entry of the sender not the nickname.
4797 Affected file is lib/silcclient/ops.h and all applications
4798 using the client operations.
4800 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Moved the calling of ops->connect() from connect_to_server_final
4803 into receive_new_id functin since that is the point when the
4804 client is actually allowed to send traffic to network. The
4805 affected file is lib/silcclient/client.c.
4807 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4810 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4811 (if needs broadcasting) instead of broadcasting the packets one
4812 by one which would make a burst in the network traffic.
4814 * Added `broadcast' argument to the functions in silcd/server.[ch]
4815 silc_server_create_new_channel[_with_id] to indicate whether
4816 to send New Channel packet to primary router.
4818 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Added new function into the silcd/server.[ch] files:
4821 silc_server_create_new_channel_with_id to create new channel with
4822 already existing Channel ID.
4824 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4825 lib/silccore/silcpacket.h. This packet is used t send list of
4826 Set Mode payloads inside one packet. Server uses this to set
4827 the modes for the channels and clients on those channels, that it
4828 announced to the router when it connected to it. The protocol
4829 specification has been updated accordingly.
4831 * The silc_server_new_channel did not handle the packet coming
4832 from normal server as it normally does not send that. However,
4833 when it announces its channels it does send it. Implemented
4834 the support for that.
4836 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4837 into the file lib/silccore/id.h.
4839 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Fixed memory leaks in the functions silc_idlist_del_client,
4842 silc_idlist_del_channel and silc_idlist_del_server in the file
4843 silcd/idlist.c. All of those leaked like a sieve.
4845 * Fixed some small memory leaks in the client's function
4846 silc_client_notify_by_server.
4848 * Added functions into silcd/server.c: silc_server_announce_clients,
4849 silc_server_announce_channels and silc_server_announce_server.
4850 These functions are used by normal and router server to announce
4851 to its primary router about clients, channels and servers (when
4852 router) that we own. This is done after we've connected to the
4855 These functions effectively implements the following packet types:
4856 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4857 and SILC_PACKET_NEW_ID_LIST.
4859 * Added new functions into the silcd/packet_receive.[ch]:
4860 silc_server_new_id_list, silc_server_new_channel_list and
4861 silc_server_new_channel_user_list to handle the incoming
4862 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4864 * Added support of changing Channel ID in the function
4865 silc_server_replace_id. If the server that announces a channel
4866 to the router already exists in the router (with same name but
4867 with different Channel ID), router is responsible to send
4868 Replace ID packet to the server and force the server to change
4869 the Channel ID to the one router has.
4871 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4872 client that the Channel ID has been changed by the router. The
4873 normal server sends this to the client. Client must start using
4874 the new Channel ID as the channel's ID.
4876 Implemented handling of this new type into lib/silcclient/client.c
4877 into the function silc_client_notify_by_server.
4879 * Added new function silc_idlist_replace_channel_id into the files
4880 silcd/idlist.[ch] to replace the Channel ID.
4882 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Call silc_server_command_identify_check always when processing
4885 the IDENTIFY command in silcd/command.c
4887 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4890 send keepalive packets. The packet can be sent by clients,
4891 servers and routers.
4893 Added function silc_socket_set_heartbeat into the file
4894 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4895 If not set, the heartbeat is not performed. The actual
4896 heartbeat is implemented in the low level socket connection
4897 library. However, application is responsible of actually
4900 Added silc_server_send_heartbeat to send the actual heartbeat
4901 packet into silcd/packet_send.[ch]. Server now performs
4902 keepalive with all connections.
4904 * Added silc_task_get_first function into lib/silcutil/silctask.c
4905 to return the timeout task with shortest timeout. There was a bug
4906 in task unregistration that caused problems. TODO has been
4907 updated to include that task system must be rewritten.
4909 * The client library will now resolve the client information when
4910 receiving JOIN notify from server for client that we know but
4911 have incomplete information.
4913 * Rewrote parts of silc_server_remove_from_channels and
4914 silc_server_remove_from_one_channel as they did not remove the
4915 channel in some circumstances even though they should've.
4917 * Encryption problem encountered in server:
4919 The LEAVE command used to send the Channel Key packet to the
4920 router immediately after generating it. However, the code
4921 had earlier sent Remove Channel user packet but not immediately,
4922 ie. it was put to queue. The order of packets in the router
4923 was that Channel Key packet was first and Remove Channel User
4924 packet was second, even though they were encrypted in the
4925 reverse order. For this reason, MAC check failed. Now, this
4926 is fixed by not sending the Channel Key packet immediately but
4927 putting it to queue. However, this is more fundamental problem:
4928 packets that are in queue should actually not be encrypted
4929 because packets that are sent immediately gets encrypted
4930 actually with wrong IV (and thus MAC check fails). So, packets
4931 that are in queue should be encrypted when they are sent to
4932 the wire and not when they put to the queue.
4934 However, the problem is that the current system has not been
4935 designed to work that way. Instead, the packet is encrypted
4936 as soon as possible and left to the queue. The queue is then
4937 just purged into wire. There won't be any fixes for this
4938 any time soon. So, the current semantic for packet sending
4941 o If you send packet to remote host and do not force the send
4942 (the packet will be in queue) then all subsequent packets to the
4943 same remote host must also be put to the queue. Only after the
4944 queue has been purged is it safe again to force the packet
4947 o If you send all packets immediately then it safe to send
4948 any of subsequent packets through the queue, however, after
4949 the first packet is put to queue then any subsequent packets
4950 must also be put to the queue.
4952 Follow these rules and everything works fine.
4954 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Added new function silc_server_remove_clients_by_server to
4957 remove all client entries from ID list when the server connection
4958 is lost. In this case it is also important to invalidate all
4959 client entires as they hold the invalid server entry. This
4960 fixes fatal bug when server has lost connection and will reconnect
4963 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Made some sanity checks to silc_server_daemonise like to check
4966 whether the requested user and group actually exists.
4968 * Added sanity check to SKE's silc_ske_responder_finish to check
4969 that the public and private key actually is valid.
4971 * Invalidate the client's nickname when receiving Replace ID
4972 packet and the Client ID is being replaced. This means that the
4973 server will query the nickname if someone needs it (client)
4976 * Sort the ID Cache in client library when the ID Cache data
4977 has changed (needs sorting).
4979 * Do not allow for SILC client to create several connections to
4980 several servers. The client does not support windows right now
4981 and generating multiple connections causes weird behaviour.
4983 Irssi-silc client does support windows and can handle several
4984 connections without problems, see: www.irssi.org and SILC plugin.
4986 * Fixed some places where client was added to the IDList. The
4987 rule of thumb is following (in order to get everything right):
4988 If the client is directly connected local client then the
4989 `connection' argument must be set and `router' argument must be
4990 NULL to silc_idlist_add_client function. If the client is not
4991 directly connected client then the `router' argument must
4992 bet set and the `connection' argument must be NULL to the
4993 silc_idlist_add_client function.
4995 * The funtion silc_server_packet_send_local_channel actually did
4996 not check whether the client was locally connected or not. It
4997 does that now. Fixed a bug related to LEAVE command.
4999 * Fixed Remove Channel User payload parsing bug in server's
5000 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5002 * The server's silc_server_save_channel_key now checks also the
5003 global ID list for the channel as it might not be in the local
5004 list. Fixed a bug related to LEAVE command.
5006 * Is this the end of the [<unknown>] buglet that has been lurking
5007 around for a long time? A little for loop fix in server's
5008 silc_server_command_whois_parse that is used by both IDENTIFY
5009 and WHOIS command. At least, this was a clear bug and a cause
5010 of one type of [<unknown>] buglet.
5012 * WHOIS and IDENTIFY commands call the function
5013 silc_server_command_[whois/identify]_check function even if
5014 we are not router server.
5016 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Added --with-gmp configuration option. If set the GMP
5019 is always compiled in the SILC source tree. If not set then
5020 it is checked whether the system has the GMP3 installed. If
5021 it has then the GMP won't be compiled (the system's headers
5022 and library is used), if it doesn't have it then the GMP is
5023 compiled in the SILC source tree.
5025 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Changed RSA private exponent generation to what PKCS #1
5028 suggests. We try to find the smallest possible d by doing
5029 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5030 not security fix but optimization.
5032 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5034 * Added new config entry [Identity] to fork the server and run
5035 it as specific user and group. A patch from Bostik.
5037 * Imported Dotconf configuration library into lib/dotconf.
5038 This will be used to create the SILC configuration files later.
5039 It will appear in the distsribution after this commit.
5041 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * A big code auditing weekend happening. Auditing code for
5044 obvious mistakes, bugs and errors. Also, removing any code
5047 Removed files for being obsolete:
5049 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5050 inline in the file lib/silcutil/silcbuffer.h)
5052 o lib/silcutil/silcbufutil.c (the header has inline versions)
5054 Changed code to fix possible error conditions:
5056 o The buffer formatting routines now check that the destination
5057 buffer really has enough space to add the data. This applies for
5058 both buffer formatting and unformatting
5059 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5060 unformatting was changed to accomodate following rules:
5061 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5062 sent to the function while XXX_*STRING will not allocate or copy
5063 the data into the buffer. Instead it sets the pointer from the
5064 buffer into the pointer sent as argument (XXX_*STRING used to
5065 require that the pointer must be allocated already). This change
5066 makes this whole thing a bit more consistent and more optimized
5067 (note that the data returned in the unformatting with XXX_*STRING
5068 must not be freed now). The routines return now -1 on error.
5070 o Tried to find all code that use buffer_format and buffer_unformat
5071 and added return value checking to prevent formatting and
5072 especially unformatting errors and possible subsequent fatal
5075 o Changed ske->x and ske->KEY to mallocated pointers in
5076 lib/silcske/silcske.h. Fixed possible data and memory leak.
5078 o Added return value checking to all *_parse* functions. Fixed
5079 many memory leaks as well.
5081 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5082 so that buffer overflows would not happen. All code now also
5083 checks the return value as it can fail.
5085 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added reconnection support to server if the normal server looses
5088 its connection to the router (for example if router is rebooted).
5089 The server performs normal reconnection strategy implemented
5090 to the server. Affected file silcd/server.c.
5092 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Added new packet type SILC_PACKET_SET_MODE that is used to
5095 distribute the information about changed modes (for clients,
5096 channels and clients channel modes) to all routers in the
5097 network. Updated the protocol specification accordingly.
5099 Added functions into silcd/packet_send.c and
5100 silcd/packet_receive.c: silc_server_send_set_mode,
5101 silc_server_set_mode.
5103 Added new files silcmode.[ch] into lib/silccore that implements
5104 the encoding and decoding of Set Mode Payload. Added new type
5105 SilcSetModePayload. Moved the definitions of different modes
5106 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5108 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Oops, a little mistake in server's connection authentication
5111 protocol. The protocol is not ended with FAILURE but with
5112 SUCCESS if the authentication is Ok. :) Affected file is
5115 * Implemented NICK_CHANGE notify handling in server in the file
5116 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5117 the local clients on the channel. After the changing nickname
5118 in router environment snhould work and the [<unknown>] nickname
5119 should appear no more.
5121 The silc_server_replace_id function that receives the Replace ID
5122 payload now sends the NICK_CHANGE notify type also in the file
5123 silcd/packet_receive.c
5125 * Changed WHOIS and IDENTIFY command to support the maximum amount
5126 of arguments defined in protocol specs (3328 arguments). This
5127 fixed a bug that caused problems when there were more than three
5130 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Added extra parameter, command identifier, to the
5133 silc_client_send_command so that explicit command identifier
5136 Changed that ID list routines uses specific command identifier
5137 when sending WHOIS/IDENTIFY requests to the server so that they
5138 can be identified when the reply comes back.
5140 Affected files lib/silcclient/command.[ch],
5141 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5143 * Added `sender' argument to silc_server_packet_send_to_channel
5144 to indicaet the sender who originally sent the packet to us
5145 that we are now re-sending. Ignored if NULL. Affected file
5146 silcd/packet_send.[ch].
5148 * Added some server statistics support in silcd/server_internal.h
5149 SilcServerStatistics structure and around the server code. Also
5150 send some nice statistics information when client is connecting
5153 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Fixed channel ID decoding in server's JOIN command reply in
5156 silcd/command_reply.c
5158 * Fixed braodcasting of replace ID payload to not to send it if
5159 we are standalone server in silcd/packet_receive.c.
5161 * Fixed all channel message sending routines to not to send
5162 packets to clients that has router set, since they are routed
5163 separately in the same function earlier. Affects file
5164 silcd/packet_send.c and all channel packet sending functions.
5166 * In USERS reply, res_argv[i] are not allocated, the table
5167 is allocated. Thus changed that free the table, not its
5170 * In server's whois_check and identify_check if the client is
5171 locally connected do not send any WHOIS commands - they are not
5174 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Fixed some minor bugs in client when sending WHOIS command. The
5177 arguments was in wrong order.
5179 * Removed statis function add_to_channel from server in
5180 silcd/command.c that was previously used with the joining but
5183 * Tested USERS command in router environment successfully with two
5184 routers, two servers and two clients.
5186 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Reorganized the USERS command and command reply in client library
5189 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5190 When the command is given by user we register a pending command
5191 callback that will reprocess the command after the reply has been
5192 received from the server. When reprocessing the packet we then
5193 display the information. Thus, the USERS information is displayed
5194 now in the command callback instead of in the command reply
5195 callback. The processing of the command is same as previously
5196 when server has sent the command reply in the JOINing process.
5198 * Added to USERS command in silcd/command_reply.c to join the client,
5199 we didn't use to know about, to the channel after we've created
5200 a client entry for it. Also, for clienet we did know already still
5201 check whether it is on the channel or not and add it if not.
5203 * Removed silc_server_command_join_notify as the function and its
5206 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Changed the client's pending command handling to the same as the
5209 server's pending command handling. It is also now possible to
5210 execute command reply functions from other command reply
5211 function as the function callbacks for commands and command
5212 replies are one and same. The pending commands are not static
5213 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5214 in client connection context. Thus, pending commands are server
5215 connection specific as it is convenient.
5217 Changed the function silc_client_command_pending and
5218 silc_client_command_pending_del and added new function
5219 silc_client_command_pending_check. Removed the
5220 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5223 * Added cmd_ident, current command identifier, to the client
5224 connection context in lib/silcclient/client.h to keep track on
5225 command identifiers used in command sending. Client's command reply
5226 function handling now supports the mandatory command identifiers.
5228 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5229 funtions in client to fully support pending command callbacks.
5231 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5232 as one of the arguments to the application in the command reply
5235 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5236 before first releasing SILC but came back. Now it is removed again
5237 and should come back nomore. The FORWARDED flag was used only
5238 by the JOINing procedure by forwarding the command packet to router.
5239 Now, the JOINing procedure has been changed to more generic (due
5240 to various router environment issues) and FORWARDED is not needed
5241 anymore for anything. The protocol specification is yet to be
5244 Now, removed silc_server_packet_forward from server and the flag
5245 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5247 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Renamed NAMES command to USERS command. The NAMES was named that
5250 due to historical reasons. Now it is renamed. Also, rewrote
5251 parts of the USERS command. The nickname list is not sent anymore
5252 by the server. Only Client ID and mode lists are sent in the USERS
5253 command. Changed this also to the protocol specification.
5255 The client now resolves the names and stuff after it receives
5256 the USERS list from the server when joining to the channel.
5258 * WHOIS and IDENTIFY commands has been changed to support multiple
5259 Client ID's per command. One can now search for multiple users
5260 in the network by sending only one WHOIS or IDENTIFY command.
5261 Changed the code and the protocol specifications.
5263 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5264 uses silc_server_command_whois_parse to parse the request. */
5266 * If normal server, do not parse the WHOIS and IDENTIFY requests
5267 before sending it to the router. Saves some time.
5269 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Fixed JOIN command on client library. Wrong number of arguments
5272 used to crash the client.
5274 * Added silc_server_channel_has_global function to check whether
5275 channel has global users or not.
5277 * Added silc_server_channel_has_local function to check whether channel
5278 has locally connected clients on the channel.
5280 * The silc_server_remove_from_one_channel now checks whether the
5281 channel has global users or not after given client was removed from
5282 the channel. It also checks whether the channel has local clients
5283 on the channel anymore. If it does not have then the channel entry
5284 is removed as it is not needed anymore.
5286 * The silc_server_notify now checks on JOIN notify whether the joining
5287 client is one of locally connected or global. If it is global then
5288 the channel has now global users on the channel and that is marked
5289 to the channel entry. Also, it now saves the global client to
5290 global list who is joining and JOINs it to the channel. This is
5291 for normal server, that is.
5293 Changed silc_server_send_notify_on_channel,
5294 silc_server_packet_relay_to_channel and
5295 silc_server_packet_send_to_channel check if we are normal server
5296 and client has router set (ie. global client) do not send the
5297 message to that client, as it is already routed to our router.
5299 * Implemented LEAVE notify type handling in silc_server_notify
5302 * Tested LEAVE command in router environment successfully. Tested
5303 with two routers, two servers and two clients.
5307 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5309 * Implemented SIGNOFF notify type handling in silc_server_notify
5312 * silc_server_remove_id now removes the client entry from all channels
5313 it has joined and thusly sends SIGNOFF notify type.
5315 * Rewrote the NAMES list generation in server by removing two excess
5316 loops. The lists are created now inside one loop.
5318 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * silc_server_remove_channel_user checks now also global list
5321 for channel and client.
5323 * silc_server_new_channel_user checks now both local and global
5324 list for channel and client. Fixed a bug in client id decoding.
5325 Used to decode wrong buffer.
5327 * silc_server_channel_message checks now both local and global
5328 list for channel entry.
5330 * Tested channel joining (hence JOIN) in router environment
5331 successfully. Tested with two routers, two servers and two
5334 * Tested channel message sending in router environment successfully.
5336 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Added silc_server_save_channel_key into server.[ch] to save the
5339 received channel key in Channel Key payload processing. It is
5340 also used in JOIN command reply handling.
5342 Equivalent function silc_client_save_channel_key added into
5343 client.[ch] into client library.
5345 * Changed JOIN command reply to send information whether the channel
5346 was created or not (is existing already) and the channel key
5347 payload. Changed protocol specs accordingly.
5349 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5350 the request was sent by ID and not by nickname. Crashed on
5353 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5356 now correctly save the received data.
5358 * silc_server_free_sock_user_data now notifies routers in the
5359 network about entities leaving the network.
5361 At the same time implemented functions silc_server_remove_id
5362 and silc_server_send_remove_id to receive and send REMOVE_ID
5363 packets. The packet is used to notify routers in the network
5364 about leaving entities. The ID removed will become invalid in
5367 * Added function silc_idlist_del_server into server. Removes and
5368 free's server entry from ID list.
5370 * silc_server_private_message function now checks, if we are router,
5371 that the destination ID really is valid ID, naturally.
5373 * In router when NEW_ID packet is received (for new client) the
5374 hash of the Client ID is saved in the ID Cache but the
5375 client->nickname is set to NULL, instead of putting the hash
5378 IDENTIFY command now also checks that client->nickname must be
5379 valid. If it is not if will request the data from the server who
5380 owns the client. Added new function
5381 silc_server_command_identify_check.
5383 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5384 to set the command to already allocated Command Payload.
5386 * Tested private message sending in router environment with two
5387 routers, two servers and two clients. Fixed minor bugs and now
5390 * Fixed segfault from client's NAMES command. Used to crash if
5393 * Forwarded packets must not be routed even if it is not destined
5394 to the receiver. Changed server code comply with this.
5396 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Added `require_reverse_mapping' boolean value to ServerParams
5399 structure. If TRUE (not default) the server will require that
5400 the connecting host has fully qualified domain name.
5402 If the reverse mapping is not required and hostname could not be
5403 found the IP address is used as hostname.
5405 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Implemented version string checking to both client and server.
5408 The check is incomplete currently due to the abnormal version
5409 strings used in development version of SILC.
5411 * Changed all command functions in server to use the new
5414 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Changed char *data to unsigned char *data in ID Cache system to
5417 support binary data as ID Cache data. Changed code to support
5418 binary data in lib/silccore/idcache.c.
5420 * Renamed silc_server_packet_relay_command_reply to
5421 silc_server_command_reply as it is normal packet receiving
5422 function. Rewrote the function to accept command replys for
5423 servers and not only for clients.
5425 * Mark remote router always as registered server if we are connecting
5426 to it. Otherwise, commands sent by the router to us are ignored.
5428 * All ID List find routines now returns the ID Cache Entry pointer
5429 as well if requested.
5431 * WHOIS command works now in router environment, tested with two
5432 routers, two servers and two clients.
5434 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5435 in router environment (as it is almost equivalent to WHOIS) but
5436 hasn't been tested thoroughly. Added new functions:
5438 silc_server_command_identify_parse
5439 silc_server_command_identify_send_reply
5440 silc_server_command_identify_from_client
5441 silc_server_command_identify_from_server
5443 * Disabled route cache adding because adding two different ID's with
5444 same IP replaces the old cache entry thus giving wrong route.
5445 The entry->router->connection is always the fastest route anyway
5446 so route cache may not be needed. Of course, new routes maybe
5447 established after receiving the ID when the entry->router->connection
5448 might not be anymore the most optimal.
5450 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Add route cache for received ID for fast routing.
5454 * Added silc_server_packet_route to route received packet on router
5455 that is not destined to us.
5457 * Renamed silc_server_get_route to silc_server_route_get.
5459 * Added id_string and id_string_len fields into SilcServer to
5460 include encoded ServerID for fast comparing without excess
5461 encoding of the ID's.
5463 * Cleaned up WHOIS command on server side. Added following static
5466 silc_server_command_whois_parse
5467 silc_server_command_whois_check
5468 silc_server_command_whois_send_reply
5469 silc_server_command_whois_from_client
5470 silc_server_command_whois_from_server
5472 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5473 arguments in command replies. All command functions should be
5474 updated to use this macro.
5476 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Minor typo fixes on command reply handling on server.
5480 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added silc_server_command_add_to_channel internal routine to add
5483 the client to the channel after router has created the channel and
5484 sent command reply to the server.
5486 * Added generic silc_server_send_command to send any command from
5489 * Use static buffer with ID rendering instead of duplicating data.
5491 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Fixed a channel user mode bug when joining to a channel server gave
5494 everybody channel founder rights, oops.
5496 * We mark ourselves as the router of the incoming server connection
5497 if we are router ourselves. This way we can check in some packet
5498 sending functions whether it is locally connected server. For
5499 incoming router connections we put NULL.
5501 * For router sending packets locally means now always sending the
5502 packet cell wide; to local clients and local servers. For normal
5503 server sending packet locally means sending it to only local
5506 * Fixed the JOIN command to really work in router environment. If the
5507 channel is created it is always created by the router. Router is
5508 also responsible of making the initial joining to the channel,
5509 sending JOIN notify to the sending server and distributing
5510 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5511 does not exist server doesn't do anything else but forward the
5512 command to the router which performs everything.
5514 * Added silc_server_send_channel_key function to send the Channel Key
5517 * Added silc_server_create_channel_key to create new channel key. The
5518 channel key is now re-generated everytime someone joins or leaves
5519 a channel, as protocol dictates. Note: channel->key_len is the
5522 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5525 packet_receive.[ch] to separate packet sending and receiving
5526 routines. The server.[ch] now includes everything else including
5527 actual packet processing (writing and reading data) and other
5530 Renamed silc_server_private_message_send_internal to
5531 silc_server_send_private_message. The routine is still though
5532 used only to relay private messages as server does not send
5533 private messages itself.
5535 Renamed silc_server_new_channel to silc_server_create_new_channel
5536 and added new function sicl_server_new_channel that handles the
5537 incoming New Channel packet. Added also new sending function
5538 silc_server_send_new_channel to send New Channel Payload.
5540 * Added new function silc_server_notify to process incoming notify
5541 packet to the server/router. Server may then relay the notify
5542 to clients if needed.
5544 * Added new function silc_server_new_channel_user to process incoming
5545 New Channel User packet. Router will redistribute the packet and
5546 send JOIN notify to its local clients and locally connected servers
5547 if needed. Normal server will send JOIN notify to its local client
5548 on same channel when received this packet. Added also corresponding
5549 sending function silc_server_send_new_channel_user to sent the
5552 * Added boolean route argument to send_notif_to_channel and
5553 packet_send_to_channel functions to attempt to route the packet
5554 if it is TRUE and send only locally if it is FALSE.
5556 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * silc_server_replace_id now broadcasts the received replace ID
5559 packet if it is not broadcast packet already. The router must
5560 broadcast to inform other routers about changed ID.
5562 * Added backpointer to server's router into SilcServer context in
5563 silcd/server_internal.h.
5565 * Fixed silc_server_packet_broadcast to send correct broadcast
5568 * The channel key is now distributed to the local client as soon
5569 as it is received from the router (in router environment) so that
5570 no other packet may be sent for the channel until client has
5573 * silc_server_remove_channel_user now broadcasts the received
5574 Remove Channel User packet if it is not broadcast packet already.
5575 The router must broadcast to inform other routers about removed
5578 * Added users field into SilcPacketContext that is a reference count
5579 of the context. One can increase the reference count by calling
5580 silc_packet_context_dup which is now changed to just increase the
5581 reference count instead of duplicating the data. The reference
5582 count is decresed by calling silc_packet_context_free that will
5583 free the data after the reference count hits zero.
5585 For now on the packet context and everything allocated into it
5586 (including the raw packet from network) must be freed by calling
5587 the new silc_packet_context_free function. Added also new function
5588 silc_packet_context_alloc that must be used now to allocate the
5589 context. This also means that if a routine is asynchronous from
5590 silc_[client/server]_packet_parse_type the packet context must
5591 be duplicated by calling silc_packet_context_dup. Otherwise it
5592 gets free'd after silc_[client/server]_packet_parse_type returns.
5593 Also, one must remember that if packet is duplicated then its
5594 reference count must be decresed by calling the free function as
5595 many times as it was duplicated.
5597 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5598 from both client and server.
5600 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Made joining to a channel working in router environment.
5604 * Cleaned up JOIN command on server side and create function
5605 silc_server_command_join_channel internal routine to make the
5608 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Changed silc_command_pending list to SilcDList. Also, added
5611 `ident' field to SilcServerCommandPending structure to identify
5612 the reply and to call correct callback.
5614 Added silc_server_command_pending_check function to replace the
5615 corresnponding macro. The silc_command_pending list is not
5618 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5619 to set identifier to previously allocated Command Payload. It
5620 is used to set identifier for command when resending Command
5623 * Added silc_command_payload_encode_payload to encode Command
5624 Payload buffer from SilcCommandPayload structure.
5626 * Added silc_argument_payload_encode_payload to encode Argument
5627 payload buffer from SilcArgumentPayload structure.
5629 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Changed WHOIS command to support router connection on server side.
5632 The whois request is always sent to router unless the server is
5633 standalone server. After server has received the reply from the
5634 router will it send the reply to the client.
5636 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5637 broadcast received broadcast packet. The function is used only
5638 by router. The broadcast packet is always sent to the router's
5641 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5642 render given ID to printable string, for log files for example.
5644 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Made basic router to router connections working. At least they
5647 can now connect to each other but nothing really works the way
5648 they are supposed - yet.
5650 * Added new initiator token to RouterConnection configuration
5651 file in silcd/serverconfig.[ch]. It is used to tell whether we
5652 are the initiator to the remote router or whether we'll expect
5653 the other end to connect.
5655 * Moved registering of listener task to silc_server_init, hence
5656 the server starts listenning as soon as it is run, even if it
5657 does not have connections to other routers. Let's see how well
5660 * Changed default connection retry timeouts for more suitable in
5663 * Removed cipher and such arguments from silc_idlist_add_client
5664 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5665 Added new function silc_idlist_add_data to add the keys and stuff
5668 * Added SilcIDListData structure and added it to SilcClientEntry
5669 and SilcServerEntry as their first field in the structure. This
5670 way we can explicitly cast the ID entries to the SilcIDListData
5671 structure and get common data for the entries. In past, we had
5672 to first check what type of connection it is and then cast it to
5673 correct ID entry type. Now, we can directly cast the opaque
5674 pointer to the SilcIDListData (no matter what ID entry it actually
5675 is) and get the data needed.
5677 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5680 in some circumstances even if threre were timeout tasks, though not
5681 IO tasks, but tasks anyway. Now fixed.
5683 * Defined SilcServerConnection structure to hold connection specific
5684 stuff about directly connected servers and routers. The definition
5685 is currently in silcd/server_internal.h. I thought about having
5686 a bit more important role fro this struct but for now it is used
5687 only when connecting to other server (or router actually).
5689 * Added connecting retry support in server when connecting to
5690 router(s). The retry feature implement exponential backoff
5691 algorithm. Also, added SilcServerParams structure to hold default
5692 parameters for server. For now, it include these retry settings
5693 and are hard coded. After server is moded to be as Silc Server
5694 Library this structure will be more important.
5696 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Changed client librarys channel->clients table to SilcList and
5699 changed code accordingly.
5701 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Changed client's channel table to SilcList and changed code
5704 accordingly. Also changed SilcChannelClientEntry to include back-
5705 pointer to the channel so that client entry can use that structure
5706 as list as well and we have fast cross-reference to the channel.
5707 This change dramatically decreased the complexity of channel
5708 handling with client entry and vice versa (removed one extra
5709 loop when searching for channel entry from many functions).
5711 * Changed server->sim from table to SilcDList and changed code
5714 * NAMES command can now be used from user interface. It will show
5715 the user list on the channel, neatly.
5717 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5718 Code now saves realname of the user if it becomes available.
5720 * Renamed configure.in to configure.in.pre and made ./prepare
5721 script to automatically add correct version string to
5722 configure.in which it creates from configure.in.pre.
5724 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * NAMES command reply now shows users mode with the nickname when
5729 * Moved silc_client_ch[u]mode[_char] functions from
5730 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5731 place sucks, they are utility functions and should be in some
5734 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5736 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5739 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added TRQ (efficient deque and list library) into lib/trq. This is
5744 a very good list library that is currently used in the SILC. Defined
5745 SilcList API over the library because I didn't like the API very
5746 much. See lib/trq/silclist.h for the API and examples of how to
5747 use the API. Fixed various places in the code to use the new
5748 SilcList API. The SilcList is meant for lists that has a structure
5749 already defined as a list. It is not suitable to add just some
5750 context to the list (in TRQ, the context is the list actually).
5752 So, I defined SilcDList that can be used for the purpose where
5753 predefined list structure does not exit. This can be used as
5754 such list. Now some context just can be added to the SilcDList.
5755 Currently this list is not used in the SILC just yet, though there
5756 are a lot places where this can replace dynamically allocated
5757 tables and I will fix these places, later, to use SilcDList.
5758 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5759 and use TRQ internally).
5761 Also fixed some annoying warning messages that the original TRQ
5762 code generated. Also minor changes to TRQ's Makefile.in.
5764 * Added support for querying by Client ID to both WHOIS and
5765 IDENTIFY commands into server, as required by the protocol.
5767 * Removed method function pointers from SilcBuffer structure. They
5768 weren't used to anything and just increased the context size for
5769 no good reason. This change also made silc_buffer_alloc and
5770 silc_buffer_free functions inline functions.
5772 * Disabled command flooding detection support until it's fixed so
5773 that it accepts commands in but does not execute them more than once
5776 * Added silc_net_localhost(), to return local hostname, into
5777 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5778 that must be initialized before calling silc_client_init.
5780 * Added new function: silc_server_send_notify_on_channels to send
5781 notify messages to all channels client has joined. It is assured
5782 that the message is sent only once per client.
5784 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5785 lib/silcutil/silcutil.[ch] as silc_format function. The new
5786 function is generic and is used by server as well, not only by
5787 the logging routines.
5789 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5790 the provided version string was not acceptable. Added new function:
5791 silc_ske_check_version into lib/silcske/silcske.h. The function
5792 must be implemented by the application (client or server) and it
5793 does not reside in the SKE library. The function checks the version
5794 string remote end sent.
5796 * Added back pointers (to opaque context and to SilcSocketConnection)
5797 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5799 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5800 duplicate packet context structure.
5802 * Changed `notify' client operation to send same arguments as client
5803 receives from server except for ID's. ID's are mapped to correct
5804 ID entry and that is returned. Also, if channel entry is not sent
5805 by server but the notify is for channel the channel entry is sent
5806 to application (otherwise application doesn't know that it is for
5807 channel (library gets it from packet's Destination ID)).
5809 * Added silc_client_remove_from_channels into client library to
5810 remove a client from all channels it has joined to. Used when
5811 received SIGNOFF notify from server. Added also new function
5812 silc_client_replace_from_channels to replace old ID entry with
5813 new ID entry on all channels. Used when received NICK_CHANGE
5816 * Fixed ID Cache list handling in silc_idlist_get_client in
5817 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5818 to get (or query) client by ID.
5820 * Updated TODO list.
5822 * Added connection authentication status message defined by the
5823 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5824 support for these into the code in client and server side.
5826 * Added generic function silc_client_send_command to send any command
5827 with variable argument list. Application should use this function
5828 to send commands if the command functions provided by the library
5829 does not suite for the application's user interface needs.
5831 * Added new `failure' client operation. Application is notified about
5832 received failure packet if client is executing a protocol. In this
5833 case the protocol's execution has failed.
5835 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5836 is required by the protocol.
5838 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5839 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5842 * Added status flag to SilcSKE object to indicate realtime status
5843 of the SKE protocol.
5845 * Application receives now exactly same command reply arguments as
5846 the library receives from server. However, if ID is received the
5847 corresponding ID entry is returned to the application (eg. Client
5848 ID is mapped to correct SilcClientEntry entry and that is returned).
5849 Changed command_reply client operation due to this change.
5851 * Changed all ID's in commands and in command replys as ID Payloads.
5852 Change affected both client and server side codes.
5854 All ID's sent in SILC network (with execption of ID's in SILC
5855 Packet header) are sent in ID Payload to support variable length
5858 * Server now notifies nick changes and notifies all clients on
5859 the channels about the new nickname (about the new Client ID,
5862 * Implemented CMODE command to change channel modes. Supports all
5863 channel modes defined by the protocol specs except ban and invite
5864 lists. (Also, private channel key mode is supported but support for
5865 setting private channel key in client is missing, thus, this mode
5866 has no effect on client side (except that server requires that the
5867 client uses private channel key and normal channel traffic does not
5870 Also, invite mode works per se, but INVITE command does not work
5871 yet correctly, so you can set channel as invite only channel but
5872 inviting clients to the channel does not work (it is yet to be
5873 thought what's the best way to do it).
5875 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5876 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5877 Implemented CUMODE command to change user's mode on the channel.
5878 Supports all modes defined by the protocol specs.
5880 * Added NAMES command reply to return users modes on the channel.
5882 * Removed unnecessary and slow ciphers from lib/silccrypt.
5884 * Set SO_KEEPALIVE option to connection sockets by default.
5886 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5888 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5889 redefined the Notify Payload into protocol specs.
5891 * Added silc_id_payload_parse_id to get ID directly from raw
5894 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5897 accept searching by Client ID as well.
5899 * Added support for LEAVE and SIGNOFF notify types in client library.
5901 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5902 to parse ID Payload from raw data.
5904 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added flags parameter into silc_ske_assemble_security_properties
5907 function in lib/silcske/silcske.[ch].
5909 * Changed notify client operation to fit better for notify messages
5910 sent by server. The notify payload received from server is now
5911 passed to the application (after parsing it to SilcNotifyPayload).
5912 It is application's responsibility to retrieve the arguments
5913 from the payload and show the message the way it wants. The message
5914 sent by server is implementation specific.
5916 * Changed public keys to comply with the protocol specification.
5917 Old public keys are not supported anymore and are not compatible.
5919 * Removed nickname from Channel Payload as the latest draft removed
5920 it. The client must resolve the nickname from the NAMES command
5921 reply received when it joined the channel.
5923 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5925 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Fixed some errors in protocol specification drafts.
5929 * Created lib/silccore/silcnotify.c to implement Notify Payload
5930 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5931 generic payloads described by protocol specifications. The file
5932 includes implementations for ID Payload and Argument Payload.
5934 * Changed Command Payload implementation to use the new Argument
5935 Payload. Changed command_xxxx_payload to command_payload_xxxx
5936 to comply with SILC coding conventions.
5938 * Added suppport for Argument Payload handling in Notify Payload
5939 implementation as protocol requires it. Added the new support
5940 into server and client lib as well.
5942 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Added support for multiple nicknames on same channel. [n] is
5945 added locally to the nickname if there are more than one same
5946 nicknames on the channel.
5948 * Server now sends all nicknames that matched WHOIS request.
5949 Client also shows the list received from server.
5951 * Added TOPIC command to client side. User can now set and show
5952 current topic on channel.
5954 * Added MOTD command to client and server. Also, server sends the
5955 motd when client connects to the server.
5957 * Changed version strings to comply ISO 8601.
5959 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Fixed protocol error handling in client library. It should now
5962 cope even if the SKE fails for some reason.
5964 * Made new protocol specification drafts for submitting to IETF.
5966 * Implemented TOPIC command to server in silcd/command.c.
5968 * Added two new notify types into lib/silccore/silcnotify.h:
5969 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5970 notify nickname change and topic setting/change on a channel.
5972 * API change of command_reply operation in client library. The
5973 application gets now the status type received from server as well.
5975 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5979 * Cras fixed and optimized the packet handling even further and
5980 it should work now. Minor change to the prototype of function
5981 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5983 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added new function into lib/silcutil/silcschedule.[ch]:
5986 silc_schedule_with_fd to select() a specified fd. The function
5987 returns after timeout expires or data arrives or goes. The
5988 function is used by packet routines to wait that all data is
5989 received from network.
5991 * Fixed data reading from network in lib/silccore/silcpacket.c.
5992 The code now assures that all data is read from the fd and then
5993 continues packet processing. This was a bug fix since the code
5994 used to drop some data in some circumstances.
5996 * Added new function into lib/silcclient/client.[ch]:
5997 silc_client_start_key_exchange to start key exchange after
5998 connection has been established to server. The code internally
5999 now uses this funtion but its main purpose was to provide it
6000 for applications that perform their own connecting. After
6001 application has created a connection it merely calls this
6002 function to start the key exchange between client and server.
6003 The library takes care of everything else after that.
6005 Updated also lib/silcclient/README to explain the usage of
6008 * Do not send to application information that connection has
6009 been established. Application gets notified it by connect
6012 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Applied cras's patch to add silc_schedule_one function. The
6015 function runs scheduler once and returns.
6017 * Fixed the scheduler after cras messed it up. The timeout
6018 handling works now as it's supposed to work.
6020 * Added into lib/silccore/ silcnotify.h to include notify
6021 message types support. Changed silc_server_send_notify*
6022 functions, in server.[ch], to support those new notify types.
6023 Added the support for the notify types into client library,
6024 as well. Added new notify client operation into ops.h in
6027 * Changed silc_server_packet_send_to_channel to send normal
6028 packets instead of just channel message packets. The function
6029 is now used to send the notify packets to channels. It is not
6030 used to send channel message packets anymore, as server never
6033 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6034 va_arg()s as it seems to require it nowadays. I guess, if SILC
6035 is compiled with older va_arg() the new code should work anyway.
6037 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Splitted core library. Core library (lib/silccore) includes
6040 now only SILC protocol specific core (and common) components.
6041 Created new utility library (lib/silcutil) that includes more
6042 generic purpose stuff. The stuff for util library was taken
6043 from the old core library. This was minor and easy split.
6045 * Created SILC Client Library (lib/silcclient) that includes
6046 implementation of the SILC client without user interface. This
6047 was major move from silc/ directory. The code has been changed
6048 so that it is transparent towards the user interface. The
6049 silc/ directory includes now the same user interface as before
6050 and it uses the new client library. Read lib/silcclient/README.
6051 Basicly, the client library performs everything else related
6052 to SILC except user interface handling. Also, configuration
6053 files are considered to be part of user interface and library
6054 does not handle them.
6056 This change also changed a lot of structures, function naming etc.
6057 Most important change was that SilcClientWindow object was
6058 renamed to SilcClientConnection in the client library. Created
6059 also new file lib/silcclient/ops.h. Also added new files
6060 silc/local_command.[ch] and silc/client_ops.[ch].
6062 All these changes were made to make it easier for user interface
6063 designers to create what ever user interface for the SILC client
6066 It is also expected that the server will be moved to lib
6067 directory as well and SILC Server Library will be created;
6068 sometimes in the future.
6070 * Removed Local commands from lib/silccore/silccommand.h as
6071 they are application specific and new client library does not
6072 handle any of those anymore.
6074 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6075 old client implementation in silc/.
6077 * Added support for callback functions in SILC_LOG_* macros.
6078 Application can now set its own callbacks that will be called
6079 instead of using the default functions that will always print
6080 the debug messages to stderr (or stdout). Also, debugging can
6081 now be disabled by setting silc_debug to FALSE and re-enabled by
6082 setting it to TRUE. Note, that logging will still work even
6083 if debugging is disabled.
6085 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6086 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6087 silc_log_reset_debug_callbacks.
6089 * To enable debugging in silc client one must give now -d
6090 option on command line.
6092 * Changed silc_schedule_init to automatically allocate task queues
6093 if they are not allocated before calling it.
6095 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Added GMP 3.1 into math library.
6099 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6102 a channel in SILC network. The packet is used by servers and
6103 routers to notify other routers that user has left a channel.
6104 This little feature was missing until now. Added the feature
6105 to protocol specification as well.
6107 Added functions: silc_server_send_remove_channel_user and
6108 silc_server_remove_channel_user into server.[ch].
6110 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6111 lib/silccore/silcpacket.h. However, they are not implemented
6114 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Fixed joining to a channel and sending channel messages
6117 between server and router. The channel message sending should
6118 now work inside a cell.
6120 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Fixed the private message sending between server and router.
6123 The private message sending should now work inside a cell.
6125 * Added silc_server_replace_id into server.[ch] to replace
6126 existing ID in the SILC network.
6128 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6129 and silc_idlist_replace_server_id into idlist.[ch] in server.
6131 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * Fixed the server to server connections. Server can again now
6134 connect to router. Router to router connections probably does
6137 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Added dynamic protocol registering support. Now protocols can
6140 registered and unregistered on the fly. Patch by cras.
6142 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Added lib/contrib directory to hold routines that some platforms
6145 don't have but are needed by SILC.
6147 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6148 into lin/contrib to provide getopt() and getopt_long() for
6149 those who don't have it.
6151 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Added AWAY command to client. When away message is set and
6154 client receives a private message packet the client automatically
6155 replies to the sender with the away message.
6157 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6158 bug seemed to be the cause of recent problems when compiling
6161 * Added version detection support to SKE protocol specification
6162 and added the new changes to the SKE implementation as well.
6163 There were other minor changes in the SKE protocol as well.
6165 Many changes in lib/silcske/silcske.[ch] and in
6166 lib/silcske/payload.[ch].
6168 * Added ^U functionality, clear input line. Patch from cras.
6170 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Mainly small bugfixes on core library. Fixed some debugging
6173 logging and buffer overflow in silclog.c.
6175 * Updated config.sub and config.guess on the distribution tree.
6177 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added command lagging support in server. Client may execute
6180 commands now only once in two seconds.
6182 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Optimized packet reception. MAC computation and checking is now
6185 also more optimized. A lot previously duplicated code is now
6186 used as generic by both client and server.
6188 * Fixed key pair generation in clientutil.c
6190 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Added into lib/silccore/silcbufutil.[ch] new function;
6193 silc_buffer_realloc.
6195 * Moved generic packet sending/encryption functions to
6196 lib/silccore/silcpacket.[ch] from client and server. Some
6197 rewriting of the functions.
6199 * Moved all generic packet reception/decryption functions to
6200 lib/silccore/silcpacket.[ch] from client and server. The
6201 packet processing is now much cleaner in both client and server.
6202 These were major changes in both client and server.
6204 * Created many common functions in server to do packet sending.
6205 Previously code were duplicated a lot, this has been removed
6208 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Rewrote major parts of the ID cache system. Don't know
6211 whether it is better now or not but at least the API is more
6214 * Major rewrite on ID cache stuff on client because of the ID
6215 cache API changes. Added idlist.c to client.
6217 * Also major rewrite on ID cache stuff on server as well.
6218 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6219 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6220 in hand, instead they are all put into the ID cache system now.
6221 All server_idlist_* routines uses ID cache now instead of
6222 traversing its own lists (those lists does not exist anymore).
6223 SilcIDList though still exists. Also, SilcXXXEntry's are
6226 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Finally made the SKE implementation compliant to the protocol
6229 specification. All mp integers are now binary encoded as
6230 opposed being HEX encoded.
6232 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6235 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6236 functions: silc_[encode/decode]_pem. Also added function
6237 silc_encode_pem_file to PEM encode with newlines ('\n') for
6240 * SILC public keys are now encoded either PEM or binary. Same
6241 option is for private keys as well. By default private keys
6242 are binary encoded and public keys PEM encoded. Silly HEX
6243 encoding were removed.
6245 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6246 function to create fingerprints.
6248 * Fixed a bug in SHA1; does not change the original data anymore.
6250 * Partly implemented INFO command on client and server side.
6251 Fixed CLEAR command. Changes to SERVER command; show current
6252 server(s) when giving command without arguments. Added
6253 VERSION command to client.
6255 * Added check to server that unregistered connections cannot
6256 execute commands (unless it is specificly allowed).
6258 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Fixed screen refresh.
6262 * Fixed channel joining bug from client. On some circumstances
6263 client tried to join to a channel it had already joined.
6265 * Added public key verification process into client's protocol.c.
6266 The client now verifies the public key from user and saves
6267 it into ~./silc/serverkeys/ directory.
6269 Added into: clientutil.[ch]: silc_client_verify_server_key.
6271 * Changed SKE protocol's silc_ske_initiator_finish function
6272 to accept callback function that verifies the received public
6273 key. Removed old silc_ske_verify_public_key function.
6275 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6278 silc_pkcs_private_key[_data]_set.
6280 * Made the password and public authentication more cleaner in
6281 server's protocol.c.
6283 * Removed historic and obsolete protocol `channel_auth' from
6284 both client and server.
6286 * Removed wrong way of sending command status messages from
6287 server to client in server's command.c. The old way violated
6288 protocol specification.
6290 Changes to silccore/silccommand.[ch]: removed
6291 silc_command_encode_status_payload -> not needed anymore,
6292 changed silc_command_encode_payload_va to accept extra
6293 argument on variable argument list. The argument type must
6294 now be provided to the function. Also, added new function:
6295 silc_command_encode_reply_payload_va which is same as
6296 normal command_encode_payload_va except command status type
6297 is provided as extra argument.
6299 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Added ~./silc directory handling. The directory includes the
6302 public and private keys for the client.
6304 Added silc_client_check_silc_dir, silc_client_create_identifier
6305 and silc_client_load_keys.
6307 * Implemented SILC protocol compliant public key. Added public
6308 and private key saving to and loading from files.
6310 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6311 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6312 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6313 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6314 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6316 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6317 silc_pkcs_load_[public/private]_key.
6319 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Added silc_server_get_route (route.[ch]) to get connection
6322 data for the fastest route for given ID.
6324 * Implemented INVITE command on client and server. The command
6325 were re-defined in the SILC Protocol Specification and the
6326 implementation now complies with the specification.
6328 * Implemented PING command on client and server.
6330 * Implemented NAMES command on client and server. The server side
6331 supports currently only normal server not router server yet.
6332 Some changes to NAMES definition in SILC protocol specification.
6334 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Implemented LEAVE command on client and server.
6338 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6339 again. This change was made to the protocol as well. Server
6340 should not violate the protocol specification anymore.
6342 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6345 was tested. SOCKS4 was not but should work anyway.
